    Efforts to suppress an invasive weed are often undertaken with the goal of facilitating the recovery of a diverse native plant community. In some cases, however, reduction in the abundance of the target weed results in an increase in other exotic weeds. Mile-a-minute weed (Persicaria perfoliata (L.) H. Gross (Polygonaceae)) is an annual vine from...

    Rhinoncomimus latipes (Coleoptera: Curculionidae) is a major biological control agent against the invasive plant Persicaria perfoliata. Release of R. latipes is challenging with the current visit-and-hand release approach because P. perfoliata shows a high degree of patchiness in the landscape, possesses recurved barbs on its stems, and often spreads into hard-to-access areas. This 3-year study developed and evaluated unmanned aerial systems (UAS) for precise aerial release of R. latipes to control P. perfoliata. We have developed two UAS (i.e. quad-rotor and tri-rotor) and an aerial release system to disseminate R. latipes. These include pods containing R. latipes and a dispenser to accommodate eight pods. Results of field tests to evaluate the systems showed no significant (P > 0.05) effects on survivorship and feeding ability of R. latipes after aerial release. Our study demonstrates the potential of UAS for precision aerial release of biological control agents to control invasive plants. The aerial deployment systems we have developed, including both pods and a dispenser, are low cost, logistically practical, and effective with no negative effects on aerially released R. latipes. © 2017 Society of Chemical Industry. © 2017 Society of Chemical Industry.

    Cancer is one of the most important causes of mortality worldwide. It includes approximately 13% of death cases. This study aimed to investigate the incidence trend of common cancers in Iran during 2004-2008 to improve reporting distribution the disease. This was a retrospective study. The study population was all cases of cancer diagnosed in Iran during 2004-2008. The crude incidence rate of cancers was calculated per 100 000 people by age groups and sex. Age-standardised incidence rates (ASRs) were calculated using direct standardisation and the world standard population. Data were analysed using SPSS (version 17) and Microsoft Office Excel 2007. In this study, a total of 301 055 cases of cancer were diagnosed. ASRs were 60.51 and 84.51 in women and men respectively. Most common cancers in men were skin (ASR = 18.85), stomach (15.02), bladder (ASR = 11.25), prostate (ASR = 8.93) and colorectal (ASR = 8.29). Most common cancers in women were breast (ASR = 18.24), skin (ASR = 12.01), colorectal (ASR = 7.75), stomach (ASR = 7.05) and haematocyte (ASR = 4.01). A significant increase was observed in the incidence of cancers in the country. Therefore, it is necessary to perform screening, early diagnosis and treatment in early stages of cancers. © 2016 John Wiley & Sons Ltd.

    Full Text Available Abstract Background In 2004, as an extension of the Enhanced Primary Care (EPC program, the Australian Government introduced a policy of providing Medicare rebates for allied health services provided to patients with chronic or complex health conditions. The objective of this study was to evaluate the utilisation of podiatry services provided under this scheme between 2004 and 2008. Methods Data pertaining to the Medicare item 10962 for the calendar years 2004-2008 were extracted from the Australian Medicare Benefits Schedule (MBS database and cross-tabulated by sex and age. Descriptive analyses were undertaken to assess sex and age differences in the number of consultations provided and to assess for temporal trends over the five-year assessment period. The total cost to Medicare over this period was also determined. Results During the 2004-2008 period, a total of 1,338,044 EPC consultations were provided by podiatrists in Australia. Females exhibited higher utilisation than males (63 versus 37%, and those aged over 65 years accounted for 75% of consultations. There was a marked increase in the number of consultations provided from 2004 to 2008, and the total cost of providing EPC podiatry services during this period was $62.9 M. Conclusion Podiatry services have been extensively utilised under the EPC program by primary care patients, particularly older women, and the number of services provided has increased dramatically between 2004 and 2008. Further research is required to determine whether the EPC program enhances clinical outcomes compared to standard practice.

    The 2004-2008 eruption of Mount St. Helens (MSH), Washington, was preceded by a swarm of shallow volcano-tectonic earthquakes (VTs) that began on September 23, 2004. We calculated locations and fault-plane solutions (FPS) for shallow VTs recorded during a background period (January 1999 to July 2004) and during the early vent-clearing phase (September 23 to 29, 2004) of the 2004-2008 eruption. FPS show normal and strike-slip faulting during the background period and on September 23; strike-slip and reverse faulting on September 24; and a mixture of strike-slip, reverse, and normal faulting on September 25-29. The orientation of ??1 beneath MSH, as estimated from stress tensor inversions, was found to be sub-horizontal for all periods and oriented NE-SW during the background period, NW-SE on September 24, and NE-SW on September 25-29. We suggest that the ephemeral ~90?? change in ??1 orientation was due to intrusion and inflation of a NE-SW-oriented dike in the shallow crust prior to the eruption onset. ?? 2010 Elsevier B.V.

    Exposure to secondhand smoke increases risk for infant illness and death. The objective of this study was to estimate the prevalence of complete smoke-free-home rules (smoking not allowed anywhere in the home) among women with infants in the United States. We analyzed 2004-2008 data from the Pregnancy Risk Assessment Monitoring System on 41,535 women who had recent live births in 5 states (Arkansas, Maine, New Jersey, Oregon, and Washington). We calculated the prevalence of complete smoke-free-home rules and partial or no rules by maternal smoking status, demographic characteristics, delivery year, and state of residence. We used adjusted prevalence ratios (APRs) to estimate associations between complete rules and partial or no rules and variables. During 2004-2008, the overall prevalence of complete rules was 94.6% (95% confidence interval [CI], 94.4-94.9), ranging from 85.4% (Arkansas) to 98.1% (Oregon). The prevalence of complete rules increased significantly in 3 states from 2004 to 2008. It was lowest among women who smoked during pregnancy and postpartum, women younger than 20 years, non-Hispanic black women, women with fewer than 12 years of education, women who had an annual household income of less than $10,000, unmarried women, and women enrolled in Medicaid during pregnancy. The prevalence of complete smoke-free-home rules among women with infants was high overall and increased in 3 of 5 states, signifying a public health success. Sustained and targeted efforts among groups of women who are least likely to have complete smoke-free-home rules are needed to protect infants from exposure to secondhand smoke.

    Atmospheric tritium activity is measured regularly around Narora Atomic Power Station (NAPS) since gaseous waste, which contains tritium, is being released through a 145 m high stack at NAPS site. Atmospheric data collected during 2004-2008 shows a large variation of 3 H concentration in air, fluctuating in the range of ≤0.2-91.6 Bq.m -3 . Significantly, higher tritium levels were measured in samples near the site boundary (1.6 km) of NAPS compared to off-site locations. The atmospheric dilution factor was found to be in the range of 1.1x10 -7 -7.3x10 -7 s.m -3 . The scavenging of NAPS site was found to be varying from 0.2x10 4 to 14.1x10 4 (Bq.m -3 rain water per Bqm -3 air). The inhalation dose to a member of general public at different distances (1.6-30 km) from NAPS site was found to be in the range of 0.21 μSv.y -1 . (author)

    In the past 5 years the Icelandic Medical Journal has undergone many changes during a period of flourishing research in Iceland. The process of reviewing and editing scientific articles has been revised since the Journal joined the Medline database in 2005 and the proportion of rejected articles has risen. New columns have been launched covering medical history, professionalism, ethics and hobbies of the medical profession. We categorized all scientific articles from the period 2004-2008, that is research articles, review articles, case reports and clinical guidelines, according to types of articles and to which medical speciality or subspeciality the publication should belong. The number of scientific articles rose during the period but the number of research articles remained around 20 most years during the period. The relative proportion of research articles therefore fell whereas the number and proportion of review articles and case reports increased. Clinical guidelines ceased to appear in the Journal. The contribution of individual specialities to the Journal varied widely. Researchers amongst doctors and related professions need be encouraged to submit scientific articles to the Journal. The publication of scientific articles in English in the web-based form of the Journal may prove to be stimulating in this regard for Icelandic doctors abroad as well as for some researchers in Iceland.

    Full Text Available The pollen of mugwort, plantain, sorrel, nettle and pigweed is an important airborne allergen source worldwide. The occurrence of pollen grains in the air is a seasonal phenomenon and estimation of seasonal variability in the pollen count permits evaluation of the threat posed by allergens over a given area. The aim of the study was to analyse the dynamics of Artemisia, Plantago, Rumex, Urticaceae and Chenopodiaceae pollen season in Szczecin (western Poland in 2004-2008 and to establish a relationship between the meteorological parameters versus the pollen count of the taxa studied. Measurements were performed by the Hirst volumetric trap (model Lanzoni VPPS 2000. Consecutive phases during the pollen season were defined for each taxon (1, 5, 25, 50, 75, 95, 99% of annual total and duration of the season was determined using the 98% method. On the basis of this analysis, temporary differences in the dynamics of the seasons were most evident for Artemisia. Correlation analysis with weather parameters demonstrated that the maximum wind speed, mean and maximum air temperature, relative humidity and dew point are the main factors influencing the average daily pollen concentrations in the atmosphere.

    A case-control study was performed to investigate the association between colic of all types in Swedish horses and infection with the equine tapeworm Anoplocephala perfoliata. Colic cases were defined by clinical signs consistent with the presence of abdominal pain, and the control horses had no signs of colic within the last year but attended a clinic for other reasons. Blood and fecal samples were collected by veterinarian from 67 horses with signs of colic and 67 control horses. The sera were analyzed using serodiagnostic assay anti-12/13 kDa IgG(T) ELISA. The fecal samples, 30 g from each horse, were analyzed with a modified sugar salt flotation method with a density of 1.280. A significant association was found between the presence of A. perfoliata eggs in feces and colic with a 16 times higher risk of colic if eggs had been observed in fecal samples. However, there was no significant association between colic and the median OD-values in the serological diagnosis, nor when recommended cut-offs were used. The study concludes that A. perfoliata is a risk factor for colic in Swedish horses and it suggests that the modified flotation method can be used as a diagnostic tool for identifying horses at risk.

    Does the risk of adverse outcomes at the time of ectopic pregnancy vary by race/ethnicity among women receiving Medicaid, the public health insurance program for low-income people in the USA? Among Medicaid beneficiaries with ectopic pregnancy, 11% experienced at least one complication, and women from all racial/ethnic minority groups were significantly more likely than whites to experience complications. In this population of Medicaid recipients, African American women are significantly more likely than whites to experience ectopic pregnancy, but the risk of adverse outcomes has not previously been assessed. We conducted a cross-sectional observational study of all women (n = 19 135 106) ages 15-44 enrolled in Medicaid for any amount of time during 2004-2008 who lived in one of the following 14 US states: Arizona; California; Colorado; Florida; Illinois; Indiana; Iowa; Louisiana; Massachusetts; Michigan; Minnesota; Mississippi; New York; and Texas. We analyzed Medicaid claims records for inpatient and outpatient encounters and identified ectopic pregnancies with a principal diagnosis code for ectopic pregnancy from 2004-2008. We calculated the ectopic pregnancy complication rate as the number of ectopic pregnancies with at least one complication (blood transfusion, hysterectomy, any sterilization, or length-of-stay (LOS) > 2 days) divided by the total number of ectopic pregnancies. We used Poisson regression to assess the risk of ectopic pregnancy complication by race/ethnicity. Secondary outcomes were each individual complication, and ectopic pregnancy-related death. We calculated the ectopic pregnancy mortality ratio as the number of deaths divided by live births. Ectopic pregnancy-associated complications occurred in 11% of cases. Controlling for age and state, the risk of any complication was significantly higher among women who were black (incidence risk ratio [IRR] 1.47, 95% CI 1.43-1.53, P American Indian/Alaskan Native (IRR 1.34 95% CI 1.16-1.55, P white

    The antispasmodic activity of extracts from the aerial parts of Buddleja scordioides and Buddleja perfoliata (family: Scrophulariaceae) was studied on isolated tissue preparations from rabbit and guinea pig intestine. The chloroformic extract from the plants exhibited a significant relaxation on the spontaneous contraction of isolated rabbit jejunum at concentrations ranging from 1 to 400 microg/ml, and also caused an inhibitory effect on both K+ and Ca2+ induced contractions in the same tissue. The extracts at moderate doses (50 microg/ml) reduced 5-hydroxytryptamine (5-HT), acetylcholine and histamine induced contractions on isolated guinea pig ileum. Therefore, B. scordioides and B. perfoliata possess similar relaxant mechanism of action, in view of the fact that both inhibit K+ induce contraction and act through serotoninic, muscarinic and histaminic receptors. So, these data support the idea that the extracts may interfere either with calcium mobilization from intracellular stores, or with calcium interaction with regulatory proteins (e.g., calmodulin), or in other steps in the calcium signaling pathway. This leads us to suggest that the spasmolytic effect of both Buddleja species on smooth muscular contractility are due to the same or similar compounds occurring in these two species, which might be present in similar quantities.

    Equine Anoplocephalosis constitute a significant problem in horses worldwide. The aim of this study was to analyse intrinsic (host age and sex) and extrinsic (management type, pasture type and moisture) factors that influence the prevalence and FEC of A. perfoliata infections. Faecal samples were collected from 994 horses managed in studs or individually between 2012 and 2014. The Sedimentation-flotation method was applied for coproscopic analysis, and faecal egg counts were calculated. The overall prevalence was 25.1% (21.4-29.0) with the highest prevalence (36.1% [28.1-44.8]) found in horses 10-20 years old. The individuals kept in studs showed three times higher A. perfoliata prevalence compared to the ones managed individually. The prevalence significantly differed between pasture types, with individuals kept in studs (37.6% [34.3-40.9]) showing four times higher prevalence than horses kept individually (9.2% [4.8-16.5]). More horses kept on watery (42.0% [36.6-47.6]) and semi-watery (35.9% [31.3-40.7]) pastures were infected than those on dry (6.6% [4.6-9.2]) pastures. The overall A. perfoliata FEC in all examined individual was 2.67 and differed within sex, with mares showing 4.3 - times higher FEC of infection than stallions. Horses bred in studs (3.65±0.289) showed higher FEC than these bred individually (1.28±0.198). There was the effect of pasture type on A. perfoliata FEC, with horses kept on joint pastures (4.06±0.29) showing higher FEC than individuals kept individually (0.88±0.23). Pasture moisture significantly affected A. perfoliata FEC with the highest FECs in horses from watery pastures. Horses bred on dry pastures showed 16 times lower FEC than horses bred on watery pastures. Host age also significantly affected A. perfoliata FEC, with the oldest individuals showing the highest mean FEC. The presented analysis of intrinsic and extrinsic factors may help to overcome A. perfoliata infections in horses in different breeding systems

    Full Text Available Amino acids belong to the primary synthesis substances that are found in above-ground and underground organs of almost all flowering plants, are synthesized from simple inorganic compounds and are involved in the synthesis of proteins, coenzymes, flavonoids, steroidal compounds, polyphenols, complex carbohydrates, fats, vitamins and pigments. They are present in plants in easily digestible complexes and biologically available concentrations for a human body, and therefore have higher physiological activity comparing with synthetic analogues. Plant amino acids play an important role in the functioning of various systems and organs of the human body and are characterized by distinct pharmacological properties, as well as contribute to more rapid absorption and potentiate the effect of other biologically active compounds present in plants. Thisdetermines the relevance of selecting most valuable species of plants that contain amino acids complex. The aim of research is to study the qualitative composition and quantitative content of free and bound amino acids in the protein in Polygonum hydropiper L. and Polygonum persicaria L. herbs of Ukrainian flora. Materials and methods. Polygonum hydropiper L. and Polygonum persicaria L. herbs were collected in the summer during the phase of mass flowering (July - August 2013,VolodymyrivkaVillage, Zaporozhye Region. To confirm the qualitative composition and to detect the quantitative content of free and bound amino an acid in protein a methodology proposed by Stein and Moore, has been used; a high-performance liquid chromatograph, Model AAA 881 (Czech Republic has been used. Results. In conducting the research the content of free and bound 15 amino acids, of which 9 are essentialhas been established. Qualitative composition of the substances in both studied species was fully identified. During the experiment the content of the total amount of free and bound amino acids was established.

    Water scarcity and drought are particularly relevant phenomena in Spain, a country with a Mediterranean climate and intense pressure on existing water resources. Spain's drought management policies have evolved significantly over time, and today Spain is at the forefront of drought management and mitigation planning in Europe. However, drought management policies are not informed by comprehensive or accurate estimations of the socioeconomic impacts of drought, nor by the efficiency or efficacy of drought management and mitigation measures. Previous studies attempting to estimate on the impacts of drought are based on direct economic users of water, primarily irrigated agriculture and hydropower. Existing analyses do not take into consideration the impacts on other economic sectors, such as recreational uses, which have a growing importance from a socioeconomic perspective. Additionally, the intangible or non-market impacts (on social welfare and wellbeing and on the environment) are not considered or measured, although they can be significant. This paper presents the mid-point results of the PREEMPT project (Policy relevant assessment of the socioeconomic effects of droughts and floods, ECHO - grant agreement # 070401/2010/579119/SUB/C4), an effort to provide a comprehensive assessment of the socioeconomic impacts of the 2004-2008 drought in the Ebro river basin. The study gathers existing information on direct and indirect economic impacts of drought on different sectors, completing existing gaps and comparing the results of studies that use different methodologies. It also estimates the welfare losses resulting from domestic water use restrictions and environmental degradation as a result of the drought using a value transfer approach from results derived from value choice experiments developed for other Spanish and international river basins. Results indicate that there is a clear need to improve our knowledge of the direct and indirect impacts of drought and to

    Full Text Available Context: Vegetal extracts represent an alternative to control against agricultural pests that have become resistant to pesticides. Using natural products is considered to be more friendly to the environment and safe. Aims: To determine the insecticidal and antifeedant activity of Polygonum persicaria extracts of two differents populations in Chile (Valparaiso and Curico against Nomophila indistinctalis larvae. Methods: Insecticide Resistance Action Committee (IRAC susceptibility test was used to evaluate the insecticidal activity of the extracts at concentrations of 100, 250, 500 and 1000 mg/L; against first instar larvae of Nomophila indistinctalis. The antifeedant activity was evaluated to determine the percentage of consumption in third instar larvae on treatment. Results: When comparing the control and the treatment groups in the antifeedant activity assay, significant differences (p<0.05 were observed after 90 minutes of exposure. With respect to the insecticidal activity, all extracts showed significant effects at the applied concentrations compared to the negative control. Moreover, the dichloromethane extracts of Curico and Valparaiso at concentrations greater than 500 mg/L showed a similar insecticidal activity as compared to the commercial formulation Neem. Conclusions: This work presents for the first time the results of the anti-feeding and insecticide activity of ethanol, methanol, and dichloromethane extracts from Polygonum persicaria on Nomophila indistinctalis. The results show that the extracts of this species can be used as an alternative for biological control. In addition, the results obtained allow a bioguided fractionation for the identification of secondary metabolites present in these extracts.

    Full Text Available Proteomics is often hindered by the lack of protein sequence database particularly for non-model species such as Persicaria minor herbs. An integrative approach called proteomics informed by transcriptomics is possible [1], in which translated transcriptome sequence database is used as the protein sequence database. In this current study, the proteome profile were profiled using SWATH-MS technology complemented with documented transcriptome profiling [2], the first such report in this tropical herb. The plant was also elicited using a phytohormone, methyl jasmonate (MeJA and protein changes were elucidated using label-free quantification of SWATH-MS to understand the role of such signal molecule in this herbal species.

    Full Text Available The genus Sideritis L. belonging to Lamiaceae family is represented with more than 150 species worldwide.. The genus is represented in Turkey by 46 species and 53 taxon within two sections among which 39 are endemic. Endemism rate (79.5% in Turkey is quite high because Turkey is one of the two major gene centers of the genus. Sideritis species are known among people with different local names such as mountain tea, highland tea, sage, sarıkız tea and tail tea. According to some recent researches, extracts obtained from Sideritis species were shown to have antistress, antiulcer, analgesic, antioxidant, antibacterial, anti-inflammatory and insecticidal effects. The interest in and the demand for this plant species has increased particularly due to its antioxidant effect. Seed germination studies of this species have great importance on determination of production strategies of medical and aromatic plants. This study was conducted to determine the effects of some pre-treatments (ethylene, gibberellin, mannitol, seaweed and cold pre-treatment on germination of Sideritis perfoliata L. which is naturally grown in western Anatolia. The study was carried out at 25/15oC day/night temperature conditions. The experiments were performed according to completely randomized design with 3 replications at Adnan Menderes University, Faculty of Agriculture, Field Crops Laboratory. Significant differences were determined between applications with respect to germination rates and germination vigor values.

    Salinity affects seed germination of halophytes by inducing ionic toxicity, osmotic constraint or both. Information about the effects of salinity on seed germination of a large number of halophytes exists, but generally little is known about the basis of salinity-induced germination inhibition. In order to partition salinity effects, we studied seed germination and recovery responses of a coastal salt marsh halophyte halopeplis perfoliata to different isotonic treatments (Psi/sub S/: -0.5, -1.0, -1.5, -2.0 and -2.5, MPa) of various salts and polythylene glycol (PEG) under two light regimes (12-h light photo period and 24-h complete darkness). Highest seed germination was observed in distilled water under 12-h light photo period and reduction in osmotic potential of the solution decreased seed germination. However, some seeds of H. perfoliata could germinate in as low as -2.5 MPa (600 mM NaCl), which is equivalent to seawater salinity. Sea-salt treatment was more inhibitory than isotonic NaCl at the lowest osmotic potential (Psi/sub S/ -2.5 MPa). Generally, chloride salts with lowest Psi/sub S/ inhibited germination more than the isotonic sulfate salts. Comparable germination responses of the seeds in NaCl and isotonic PEG treatments as well as high recovery of germination in un-germinated seeds after alleviation of NaCl salinity indicated prevalence of osmotic constraint. These results thus indicate that the seeds of H. perfoliata could tolerate high levels of a wide variety of salts found in soil. (author)

    The impact on health and safety of the combination of chronic sleep deficits and extended working hours has received worldwide attention. Using the National Health Interview Survey (NHIS), an in-person household survey using a multistage, stratified, clustered sample design representing the US civilian, non-institutionalized population, the authors estimated the effect of total daily self-reported sleep time and weekly working hours on the risk of a work-related injury. During the survey period 2004-2008, 177,576 persons (ages 18-74) sampled within households reported that they worked at a paid job the previous week and reported their total weekly work hours. A randomly selected adult in each household (n = 75,718) was asked to report his/her usual (average) total daily sleep hours the prior week; complete responses were obtained for 74,415 (98.3%) workers. Weighted annualized work-related injury rates were then estimated across a priori defined categories of both average total daily sleep hours and weekly working hours. To account for the complex sampling design, weighted multiple logistic regression was used to independently estimate the risk of a work-related injury for categories of usual daily sleep duration and weekly working hours, controlling for important covariates and potential confounders of age, sex, race/ethnicity, education, type of pay, industry, occupation (proxy for job risk), body mass index, and the interaction between sleep duration and work hours. Based on the inclusion criteria, there were an estimated 129,950,376 workers annually at risk and 3,634,446 work-related medically treated injury episodes (overall injury rate 2.80/100 workers). Unadjusted annualized injury rates/100 workers across weekly work hours were 2.03 (60 h). With regards to self-reported daily sleep time, the estimated annualized injury rates/100 workers were 7.89 (10 h). After controlling for weekly work hours, and aforementioned covariates, significant increases in risk/1

    The chemical composition and antifungal activity of essential oils extracted from Buddleja perfoliata and Pelargonium graveolens were analysed to assess their efficacy as a potential alternative to synthetic chemical fungicides to protect stored grain. Essential oils were obtained by hydrodistillation, while GC-MS were used to characterize the components of theses oils. The main components identified from the essential oil of B. perfoliata were cubenol, eudesmol, germacrene D-4-ol and cis-verbenol; whereas (-)-aristolene, β-citronellol and geraniol, were identified in P. graveolens. These essential oils were tested against a panel of fungal strains isolated from stored grains. Toxicity of the essential oils was assessed using two models represented by human-derived macrophages and the brine shrimp assay. Moreover, inflammatory response of the oils was assessed by measuring secretion of the pro-inflammatory cytokines IL-6 and TNF-α using a human-derived macrophage cell line. Results show potent antifungal activity against a collection of fungi, with minimal inhibitory concentrations ranging from 0·3 to 50 μg ml(-1) for both plants. A moderated cytotoxicity was observed, but no inflammatory responses. These oils can be used as an alternative for synthetic chemical fungicides used to protect stored grains. Synthetic chemical fungicides are used to protect stored grains, but their broad use raises concerns about effects on the environment and human health. The impact of the present report is that the use of essential oils is an eco-friendly alternative for fungal control in postharvest grains with a low impact to the environment. © 2016 The Society for Applied Microbiology.

    Sesquiterpene synthase (SS) catalyzes the formation of sesquiterpenes from farnesyl diphosphate (FDP) via carbocation intermediates. In this study, the promoter region of sesquiterpene synthase was isolated from Persicaria minor to identify possible cis-acting elements in the promoter. The full-length PmSS promoter of P. minor is 1824-bp sequences. The sequence was analyzed and several putative cis-acting regulatory elements were identified. Three cis-acting regulatory elements were selected for deletion analysis which are cis-acting element involved in wound responsiveness (WUN), cis - acting element involved in defense and stress responsiveness (TC) and cis-acting element involved in ABA responsiveness (ABRE). Series of deletions were conducted to assess the promoter activity producing three truncated fragments promoter; Prom 2 1606-bp, Prom 3 1144- bp, and Prom 4 921-bp. The full-length promoter and its deletion series were cloned into the pBGWFS7 vector which contain β-glucuronidase (GUS) gene and green fluorescent protein (GFP) as the reporter gene. All constructs were successfully transformed into Arabidopsis thaliana based on PCR of positive BASTA resistance plants.

    Full Text Available In traditional Chinese medicine, Persicaria chinensis L. has been prescribed to cure numerous inflammatory disorders. We previously analyzed the bioactivity of the methanol extract of this plant (Pc-ME against LPS-induced NO and PGE2 in RAW264.7 macrophages and found that it prevented HCl/EtOH-induced gastric ulcers in mice. The purpose of the current study was to explore the molecular mechanism by which Pc-ME inhibits activator protein- (AP- 1 activation pathway and mediates its hepatoprotective activity. To investigate the putative therapeutic properties of Pc-ME against AP-1-mediated inflammation and hepatotoxicity, lipopolysaccharide- (LPS- stimulated RAW264.7 and U937 cells, a monocyte-like human cell line, and an LPS/D-galactosamine- (D-GalN- induced acute hepatitis mouse model were employed. The expression of LPS-induced proinflammatory cytokines including interleukin- (IL- 1β, IL-6, and tumor necrosis factor-α (TNF-α was significantly diminished by Pc-ME. Moreover, Pc-ME reduced AP-1 activation and mitogen-activated protein kinase (MAPK phosphorylation in both LPS-stimulated RAW264.7 cells and differentiated U937 cells. Additionally, we highlighted the hepatoprotective and curative effects of Pc-ME pretreated orally in a mouse model of LPS/D-GalN-intoxicated acute liver injury by demonstrating the significant reduction in elevated serum AST and ALT levels and histological damage. Therefore, these results strongly suggest that Pc-ME could function as an antihepatitis remedy suppressing MAPK/AP-1-mediated inflammatory events.

    A recent discovery showed small non-coding RNA known as microRNA has a crucial role in plant development and plant survival in extreme condition. In the past few years, researchers have managed to identify the various families of transcription factors that play a crucial role in regulating plant development and plant responses to stresses. This study focuses on the expression pattern of miRNA targeted transcription factor under biotic stress in a plant rich with secondary metabolite, Persicaria minor. A pathogenic fungus, Fusarium oxysporum was used in the biotic stress treatment since the previous study revealed this fungus could trigger plant defense system. Two small RNA libraries were constructed which consist of control and treated samples. In order to identify the potential target, psRobot target prediction software was used for each miRNA that shows significant change due to the infection. The result showed miR156b/c, miR172a, miR319, miR858, and miR894 were found to be targeting a wide range of transcription factors that involve in plant development and plant response towards stresses. The expression of miR156b/c and miR172 were up-regulated while the expression of miR319, miR858, and miR894 was found to be down-regulated. These results may provide a certain level of networking between those two regulatory molecules in plant genetic system under biotic stress.

    Chinese knotweed (Persicaria chinensis) is of ecological and economic importance as a high-risk invasive species and a traditional medicinal herb. However, the insects associated with P. chinensis pollination have received scant attention. As a widespread invasive plant we would expect P. chinensis to be associated with a diverse group of insect pollinators, but lack of taxonomic identification capacity is an impediment to confirm this expectation. In the present study we aimed to elucidate the insect pollinators of P. chinensis in peninsular Malaysia using DNA barcoding. Forty flower visitors, representing the range of morphological diversity observed, were captured at flowers at Ulu Kali, Pahang, Malaysia. Using Automated Barcode Gap Discovery, 17 morphospecies were assigned to 23 species representing at least ten families and four orders. Using the DNA barcode library (BOLD) 30% of the species could be assigned a species name, and 70% could be assigned a genus name. The insects visiting P. chinensis were broadly similar to those previously reported as visiting Persicaria japonica, including honey bees (Apis), droneflies (Eristalis), blowflies (Lucilia) and potter wasps (Eumedes), but also included thrips and ants.

    A review, focusing on emotion, was conducted of reported studies on the information behaviour of healthcare professionals (2004-2008). Findings were intended to offer guidelines on information services and information literacy training, to note gaps in research and to raise research interest. Databases were searched for literature published from January 2004 to December 2008 and indexed on eric, Library and Information Science Abstracts, medline, PsycINFO, Social Services Abstracts, Sociological Abstracts, Health Source: Nursing/Academic Edition; Library, Information Science & Technology Abstracts; Psychology and Behavioral Sciences Collection; Social Work Abstracts; SocINDEX with Full Text; SPORTDiscus; cinhal; and the ISI Web of Knowledge databases. Key journals were manually scanned and citations followed. Literature was included if reporting on issues concerning emotion. Emotion in information behaviour in healthcare contexts is scantily addressed. This review, however, offers some insight into the difficulty in identifying and expressing information needs; sense making and the need to fill knowledge gaps; uncertainty; personality and coping skills; motivation to seeking information; emotional experiences during information seeking; self-confidence and attitude; emotional factors in the selection of information channels; and seeking information for psychological or emotional reasons. Suggestions following findings, address information literacy programs, information services and research gaps.

    Results from chemical and isotopic analyses of water and gas collected between 2002 and 2016 from sites on and around Mount St. Helens are used to assess magmatic degassing related to the 2004-2008 eruption. During 2005 the chemistry of hot springs in The Breach of Mount St. Helens showed no obvious response to the eruption, and over the next few years, changes were subtle, giving only slight indications of perturbations in the system. By 2010 however, water chemistry, temperatures, and isotope compositions (δD and δ18O) clearly indicated some inputs of volatiles and heat associated with the eruption, but the changes were such that they could be attributed to a pre-existing, gas depleted magma. An increase of ~ 1.5‰ in the δ13C values of dissolved carbon in the springs was noted in 2006 and continued through 2009, a change that was mirrored by a similar shift in δ13C-CO2 in bubble gas emissions. These changes require input of a new source of carbon to the hydrothermal system and provide clear evidence of CO2 from an undegassed body of magma. Rising trends in 3He/4He ratios in gas also accompanied the increases in δ13C. Since 2011 maximum RC/RA values are ≥ 6.4 and are distinctly higher than 5 samples collected between 1986 and 2002, and provide additional evidence for some involvement of new magma as early as 2006, and possibly earlier, given the unknown time needed for CO2 and He to traverse the system and arrive at the springs.

    Ryan, Amy G.; Russell, James K.; Heap, Michael J.

    2017-04-01

    We present results from an experimental program designed to investigate the timescales, conditions and mechanisms responsible for the densification and lithification of volcanic gouge at Mount St. Helens (MSH). From 2004-2008, MSH produced a series of lava domes/spines that were mantled by thick layers of gouge resulting from fracturing and cataclasis at the conduit-wall rock interface. The gouge comprises fine crystal-rich rock powder containing little to no glass. The erupted gouge carapace is texturally diverse, and varies from loose granular material to moderately indurated coherent rock to fine-grained cataclasite within tens of centimeters. The spatial association of these materials suggests that the originally unconsolidated conduit-fault gouge is densified and lithified during ascent to the surface. At present the conditions, timescales and mechanisms for lithification of the glass-poor materials are unknown. Here, we present results from a series of high-temperature (T) uniaxial deformation experiments performed on natural gouge collected from MSH (spine 5). The experiments are intended to (1) establish the feasibility of experimentally densifying/lithifying natural gouge materials at laboratory conditions approximating those within the MSH conduit, and to (2) constrain the effects of T, load and time on the extents, rates and mechanisms of densification. Our experimental conditions include T up to 800°C (Tmelting), axial differential stresses up to 25 MPa and experimental times up to 90 hours. Experimental results will be compared to the physical properties (density, porosity, permeability, compressive strength and particle size distribution) of variably densified gouge samples from spines 4, 5 and 7 at MSH, tying the results from the lab to the natural system. Initial results show an increase in the amount and rate of densification with increasing experimental T, with an increase in sample shortening (axial strain) between experiments completed at 650

But what means political decision-making process? There are many theories which explain this concept: from the Game Theory to the Decision Theory and various types of Computational Agent Based Modeling. After a review of these theories, more interesting will be to follow the way of a legislative project to an adopted law in the Romanian Parliament, the way from theory to practice, the real manifestation of the concept of political decision-making. Our research is focused on women’s position in political decision-making in Romania along the 2004-2008 legislature. We opted for this legislature due to its importance derived from the necessity of adopting the EU accession legislation until 2007. This new legislation contained many provisions concerning the status of Romanian women. Our analysis starts by asking the following questions: Are the women in the Romanian Parliament involved in the political decision-making process? Can they influence the destiny of a law? In order to clarify those queries we analyze (quantitatively and qualitatively the paper registrations, but also the video records of any legislative debate which took place in the mentioned legislatures.

    The genus Persicaria is known to include species accumulating drimane sesquiterpenoids, but a comparative analysis highlighting the compositional differences has not been done. In this study, the secondary metabolites of both flowers and leaves of Persicariahydropiper, Persicariamaculosa and Persicariaminor, three species which occur in the same habitat, were compared. Using gas chromatography-mass spectrometry (GC-MS) analysis of extracts, overall 21/29 identified compounds in extracts were sesquiterpenoids and 5/29 were drimanes. Polygodial was detected in all species, though not in every sample of P. maculosa. On average, P. hydropiper flowers contained about 6.2 mg g FW(-1) of polygodial, but P. minor flowers had 200-fold, and P. maculosa 100,000 fold lower concentrations. Comparatively, also other sesquiterpenes were much lower in those species, suggesting the fitness benefit to depend on either investing a lot or not at all in terpenoid-based secondary defences. For P. hydropiper, effects of flower and leaf development and headspace volatiles were analysed as well. The flower stage immediately after fertilisation was the one with the highest content of drimane sesquiterpenoids and leaves contained about 10-fold less of these compounds compared to flowers. The headspace of P. hydropiper contained 8 compounds: one monoterpene, one alkyl aldehyde and six sesquiterpenes, but none were drimanes. The potential ecological significance of the presence or absence of drimane sesquiterpenoids and other metabolites for these plant species are discussed. Copyright © 2014 Elsevier Ltd.

    2009-01-01

    The electricity sector has entered into a phase of both challenges and opportunities. Challenges include workforce retirement, labour shortages, and increased competition from other employers to attract and retain the skilled people required to deliver on the increasing demand for electricity in Canada. The electricity sector in Canada is also moving into a new phase, whereby much of the existing infrastructure is either due for significant upgrades, or complete replacement. The increasing demand for electricity means that increased investment and capital expenditure will need to be put toward building new infrastructure altogether. The opportunities for the electricity industry will lie in its ability to effectively and efficiently react to these challenges. The purpose of this report was to provide employers and stakeholders in the sector with relevant and current trend data to help them make appropriate policy and human resource decisions. The report presented a comparative analysis of a 2004 Canadian Electricity Association employer survey with a 2008 Electricity Sector Council employer survey. The comparative analysis highlighted trends and changes that emerged between the 2004 and 2008 studies. Specific topics that were addressed included overall employment trends; employment diversity in the sector; age of non-support staff; recruitment; and retirements and pension eligibility. Recommendations were also offered. It was concluded that the electricity sector could benefit greatly from implementing on-going recruitment campaigns. refs., tabs., figs

    2013-01-01

    After 5 y of collecting data on diagnostic reference levels (DRLs), the Nuclear Safety and Radiation Protection French Inst. (IRSN) presents the analyses of this data. The analyses of the collected data for radiology, computed tomography (CT) and nuclear medicine allow IRSN to estimate the level of regulatory application by health professionals and the representativeness of current DRL in terms of relevant examinations, dosimetric quantities, numerical values and patient morphologies. Since 2004, the involvement of professionals has highly increased, especially in nuclear medicine, followed by CT and then by radiology. Analyses show some discordance between regulatory examinations and clinical practice. Some of the dosimetric quantities used for the DRL setting are insufficient or not relevant enough, and some numerical values should also be reviewed. On the basis of these findings, IRSN formulates recommendations to update regulatory DRL with current and relevant examination lists, dosimetric quantities and numerical values. (authors)

    For Freidson [(1985). The reorganisation of the medical profession. Medical Care Review, 42(1), 11-35], collegiality, or ostensible equal status amongst members of the medical profession, serves a dual purpose. It socialises members into an attitude of loyalty to colleagues and presents an image to those outside the profession that all its members are competent and trustworthy. However, Freidson saw the use of formal standards developed by one (knowledge) elite within medicine and enforced by another (administrative) elite as threatening collegiality and professional unity. Drawing on two studies in English primary medical care this paper reports the emergence of new strata or elites, with groups of doctors involved in surveillance of others and action to improve compliance in deficient individuals and organizations. Early indications are that these developments have not led to the consequences which Freidson predicted. The increasing acceptance of the legitimacy of professional scrutiny and accountability that we identify suggests that new norms are emerging in English primary medical care, the possibility of which Freidson's analysis fails to take account.

    This study aims at identifying any local trend in the appeal process and to determine if we are complying with the MHA 1983 and the Code of Practice by reviewing all the appeals to Mental Health Review Tribunals in a psychiatric hospital in South Wales for the period from 2004 to 2008. The total numbers of sections and appeals remain steady over the years. Men are slightly more detained than women mainly under Sections 2 and 3 of the MH Act 1983. The main diagnoses for detention were: bipolar affective disorder, schizophrenia and psychosis. 95% of cases had appeals and 5% referrals. A hearing was held in 52% of cases (n=60), the RMO discharged 38% of patients and the patient withdrew appeal in 10% of cases. 95% of cases were British White ethnicity. Single men tended to appeal more than women 68% vs. 32%. There was no observed trend in the result of the appeals and the proportions of appeal discharged by the hearing remained unchanged. The results of the appeals were not associated with gender, ethnicity, marital status, age or the type of section involved. The patients who were previously detained tend to appeal more, i.e. the more number of detentions, the more number of appeals. In only 12% of cases who had the hearings, the appeal was successful and the patients were discharged from their sections. The study shows steady volume of sections and appeals and the appeals are no more likely to result in discharge. The amendments of the Act 2007 also attract an increase in the appeal process especially in relation to the Community Treatment Orders and the Deprivation of Liberty. The use of both the Act and the Mental Capacity Act 2005 will increase workload for all involved practitioners. 2009 Elsevier Ltd and Faculty of Forensic and Legal Medicine.

  2. Innovative and adaptive technologies in decommissioning of nuclear facilities. Final report of a coordinated research project 2004-2008

    International Nuclear Information System (INIS)

    2008-10-01

    There are dozens of old reactors and other nuclear facilities worldwide that are either being actively dismantled or are candidates for decommissioning in the near term. A significant proportion of these facilities are situated in Member States or institutions that do not have adequate expertise and technologies for planning and implementing state of the art decommissioning projects. The technology selection process is critical in that regard. The main objective of the IAEA technical activities on decommissioning is to promote the exchange of lessons learned in order to improve the technologies, thereby contributing to successful planning and implementation of decommissioning. This should be achieved through a better understanding of the decision making process in technology comparison and selection and relevant issues affecting the entire decommissioning process. The specific objectives of the Coordinated Research Project (CRP) on Innovative and Adaptive Technologies in Decommissioning of Nuclear Facilities include the following general aspects: (a) To establish methodologies and data needs for developing concepts and approaches relevant to technology comparison and selection in decommissioning; (b) To improve and expand the database on applications and performance of various types of decommissioning technologies; (c) To address specific issues for individual decommissioning technologies and generate data relevant to their comparison and selection. It is also expected that this project, and in particular the papers collected in this TECDOC, will draw Member States' attention to the practicality and achievability of timely planning and implementation of decommissioning, especially for many smaller projects. Concluding reports that summarized the work undertaken under the aegis of the CRP were presented at the third and final research coordination meeting held in Rez, Czech Republic, 3-7 December 2007, and collected in this technical publication. Operating experience and lessons learned in full-scale applications, as well as key results in laboratory scale or pilot scale research and mathematical models, are among the most significant achievements of the CRP and have been highlighted

    The results of the laboratory studies performed by CIEMAT with the FEBEX bentonite in the context of WP3.2 of the NF-PRO Project and of the Agreement ENRESA-CIEMAT Anexo V are presented and analysed in this report. They refer to the effect of the hydraulic gradient on the permeability of bentonite, the effect of the thermal gradient on the hydration kinetics of bentonite, and the repercussion of temperature on the hydro-mechanical properties of bentonite (swelling, permeability and water retention capacity). In all the cases the bentonite has been used compacted to densities expected in the engineered barrier of a high-level radioactive waste repository. The existence of threshold and critical hydraulic gradients has been observed, both of them dependent on bentonite density and water pressures. After more than seven years of hydration, the 40-cm high bentonite columns are far from full saturation, the thermal gradient additionally delaying the process, which is very slow. Temperatures below 100 degree centigrade slightly decrease the swelling and the water retention capacity of the bentonite and increase its permeability. The information obtained improves the knowledge on the behaviour of expansive clay and will help the development of constitutive models and the interpretation of the results obtained in the mock-up and the in situ tests.

  4. Monitoring lava-dome growth during the 2004-2008 Mount St. Helens, Washington, eruption using oblique terrestrial photography

    2009-01-01

    We present an analysis of lava dome growth during the 2004–2008 eruption of Mount St. Helens using oblique terrestrial images from a network of remotely placed cameras. This underutilized monitoring tool augmented more traditional monitoring techniques, and was used to provide a robust assessment of the nature, pace, and state of the eruption and to quantify the kinematics of dome growth. Eruption monitoring using terrestrial photography began with a single camera deployed at the mouth of the volcano's crater during the first year of activity. Analysis of those images indicates that the average lineal extrusion rate decayed approximately logarithmically from about 8 m/d to about 2 m/d (± 2 m/d) from November 2004 through December 2005, and suggests that the extrusion rate fluctuated on time scales of days to weeks. From May 2006 through September 2007, imagery from multiple cameras deployed around the volcano allowed determination of 3-dimensional motion across the dome complex. Analysis of the multi-camera imagery shows spatially differential, but remarkably steady to gradually slowing, motion, from about 1–2 m/d from May through October 2006, to about 0.2–1.0 m/d from May through September 2007. In contrast to the fluctuations in lineal extrusion rate documented during the first year of eruption, dome motion from May 2006 through September 2007 was monotonic (± 0.10 m/d) to gradually slowing on time scales of weeks to months. The ability to measure spatial and temporal rates of motion of the effusing lava dome from oblique terrestrial photographs provided a significant, and sometimes the sole, means of identifying and quantifying dome growth during the eruption, and it demonstrates the utility of using frequent, long-term terrestrial photography to monitor and study volcanic eruptions.

    Local school districts are often one of the largest, if not the largest, employers in their respective communities. Like many large employers, school districts offer health insurance to their employees. There is a lack of information about the rate of health insurance premiums in US school districts relative to other employers. To assess the change in the costs of healthcare insurance in the 5 largest public school districts in the United States, between 2004 and 2008, as representative of large public employers in the country. Data for this study were drawn exclusively from a survey sent to the 5 largest public school districts in the United States. The survey requested responses on 3 data elements for each benefit plan offered from 2004 through 2008; these included enrollment, employee costs, and employer costs. The premium growth for the 5 largest school districts has slowed down and is consistent with other purchasers-Kaiser/Health Research & Educational Trust and the Federal Employee Health Benefit Program. The average increase in health insurance premium for the schools was 5.9% in 2008, and the average annual growth rate over the study period was 7.5%. For family coverage, these schools provide the most generous employer contribution (80.8%) compared with the employer contribution reported by other employers (73.5%) for 2008. Often the largest employers in their communities, school districts demonstrate a commitment to provide choice of benefits and affordability for employees and their families. Despite constraints typical of public employers, the 5 largest school districts in the United States have decelerated in premium growth consistent with other purchasers, albeit at a slower pace.

In 2004 the Advisory for Diversity and Support to Quota Holders was created. Faced with the demands of the social movement for a support room for students, the Black Conviviality Center was developed, a space opened to the entire academic community. This article presents the experience of the Advisory to 2008 and analyzes the challenges of conviviality between quota students and academic space, through a qualitative research on perceptions, feelings and expectations about the Center, in the form of questionnaires which contained an evocation question to the Center, applied to 35 college students from the System of Quotas for Blacks who attended the Center. The evocation data were analyzed using the software Evoc. The results indicate that the Center, in the analyzed period, was recognized by its users as a welcoming space, compared to a heterogeneous academic organization, marked by prejudices. The limitations and possibilities of interventions for the use of CCN are discussed, and an agenda for the Advisory is proposed, with a focus on diversity management.

  9. Concentrations, loads, and yields of select constituents from major tributaries of the Mississippi and Missouri Rivers in Iowa, water years 2004-2008

    Excess nutrients, suspended-sediment loads, and the presence of pesticides in Iowa rivers can have deleterious effects on water quality in State streams, downstream major rivers, and the Gulf of Mexico. Fertilizer and pesticides are used to support crop growth on Iowa's highly productive agricultural landscape and for household and commercial lawns and gardens. Water quality was characterized near the mouths of 10 major Iowa tributaries to the Mississippi and Missouri Rivers from March 2004 through September 2008. Stream loads were calculated for select ions, nutrients, and sediment using approximately monthly samples, and samples from storm and snowmelt events. Water-quality samples collected using standard streamflow-integrated protocols were analyzed for major ions, nutrients, carbon, pesticides, and suspended sediment. Statistical data summaries of sample data used parametric and nonparametric techniques to address potential bias related to censored data and multiple levels of censoring of data below analytical detection limits. Constituent stream loads were computed using standard pre-defined models in S-LOADEST that include streamflow and time terms plus additional terms for streamflow variability and streamflow anomalies. Streamflow variability terms describe the difference in streamflow from recent average conditions, whereas streamflow anomaly terms account for deviations from average conditions from long- to short-term sequentially. Streamflow variability or anomaly terms were included in 44 of 80 site/constituent individual models, demonstrating the usefulness of these terms in increasing accuracy of the load estimates. Constituent concentrations in Iowa streams exhibit streamflow, seasonal, and spatial patterns related to the landform and climate gradients across the studied basins. The streamflow-concentration relation indicated dilution for ions such as chloride and sulfate. Other constituent concentrations, such as dissolved organic carbon and suspended sediment, increased with streamflow. Nitrogen concentrations (total nitrogen and nitrate plus nitrite) increased with low and moderate streamflows, but decreased with high streamflows. Seasonal patterns observed in constituent concentrations were affected by streamflow, algae blooms, and pesticide application. The various landform regions produced different water-quality responses across the study basins; for example, total phosphorus, suspended sediment, and turbidity were greatest from the steep, loess-dominated southwestern Iowa basins. Nutrient concentrations, though not regulated for drinking water at the study sites, were high compared to drinking-water limits and criteria for protection of aquatic life proposed for other Midwestern states (Iowa criteria for aquatic life have not been proposed). Nitrate plus nitrite concentrations exceeded the drinking-water limit [10 milligrams per liter (mg/L)] in 11 percent of all samples at the 10 sites, and exceeded Minnesota's proposed aquatic life criteria (4.9 mg/L) in 68 percent of samples. The Wisconsin standard for total phosphorus (0.1 mg/L) was exceeded in 92 percent of samples. Ammonia standards, current during sample collection and at publication of this report, for protection of aquatic life were met for all samples, but draft criteria proposed in 2009 to protect more sensitive species like mussels, were exceeded at three sites. Loads and yields also differed among sites and years. The Big Sioux, Little Sioux, and Des Moines Rivers produced the greatest sulfate yields. Mississippi River tributaries had greater chloride yields than Missouri River tributaries. The Big Sioux River also had the lowest silica yields and total nitrogen and nitrate yields, whereas nitrogen yields were greater in the northeastern rivers. The Boyer and Nishnabotna River total phosphorus yields were the greatest in the study. The Boyer River orthophosphate yields were greatest except in 2008, when the Maquoketa River produced the greatest yield. Rivers in southwestern Iowa's Western Loess Hills and Steeply Rolling Loess Prairie ecoregions had the greatest suspended-sediment yields, whereas the smallest yields were in the Big Sioux and Wapsipinicon Rivers. In the 10 Iowa rivers studied, combined annual total nitrogen stream transport ranged from 3.68 to 9.95 tons per square mile per year, and total phosphorus transport ranged from 0.138 to 0.570 tons per square mile per year. Six-month loads relative to fertilizer use ranged from 8 to 56 percent for nitrogen, and 1.0 to 11.1 percent for phosphorus. The smallest loads relative to fertilizer use for both nitrogen and phosphorus occurred in July-December of dry years, and the largest nitrogen and phosphorus loads relative to use were in wet years from January-June.

    The association between overweight/obesity and dental caries in children is contentious with studies variously reporting positive or negative associations between the two conditions. Since 1995, Australia has experienced a rise in the prevalence of both conditions in its children. This study investigated the association between child weight, diet and dental problems in a nationally representative sample. Data from 4149 children (51.5% male) participating in the Longitudinal Study of Australian Children (LSAC) were used. The LSAC is a longitudinal study collecting data from a large representative cohort of Australian children; data from the first three waves were included with children aged 4-5 years, 6-7 years, and 8-9 years. Multivariate cross-sectional and prospective analyses were conducted to determine the relationships between child weight, diet and dental problems. Overweight/obesity was associated with sweet drink consumption and dental problems associated with consumption of fatty foods and sweet drinks. Underweight was associated with dental problems cross-sectionally, but both underweight and overweight at age 6-7 years predicted dental problems at age 8-9 years. Dental caries and body weight are influenced by diet. Overweight children may be consuming less fatty food but appear to be consuming more sweet drinks than normal-weight children, which can lead to both increased weight and dental caries. Dietary interventions designed to reduce the development of dental caries may also reduce the development and maintenance of overweight. © 2012 The Authors.

    Mumps is a contagious vaccine-preventable viral disease that is experiencing a revival in students attending second and third level colleges. Large mumps outbreaks have been reported in several countries despite the presence of childhood immunisation programmes over many years, including measles, mumps, and rubella (MMR) vaccination. In 2008, 1,377 cases of mumps were notified in Ireland and 1,734 in the first three months of 2009 (provisional data). This paper reviews the recent epidemiology of mumps in the Mid-West region of Ireland and highlights preventive measures. A substantial proportion of cases were not laboratory-confirmed and it is important that doctors continue to notify suspected cases. In the Irish Mid-West, data from enhanced surveillance shows a high proportion of mumps in the age group 15-24 years. Complications were uncommon and rarely severe. Where data were available, over half of the cases did not recall having received two doses of MMR, but most recalled one dose. Parents should continue to ensure children receive both MMR vaccinations so that uptake is optimal for protection. Steps were taken to increase awareness of the disease in the school, college and university settings. Preventive measures implemented to limit mumps transmission in the school\\/college setting over recent years included vaccination of close contacts, isolation for five days and hand hygiene.

  14. Concentrations and loads of nutrients in the tributaries of the Lake Okeechobee watershed, south-central Florida, water years 2004-2008

    Lake Okeechobee in south-central Florida is the second largest freshwater lake in the contiguous United States. Excessive phosphorus loading, harmful high and low water levels, and rapid expansion of non-native vegetation have threatened the health of the lake in recent decades. A study was conducted to monitor discharge and nutrient concentrations from selected tributaries into Lake Okeechobee and to evaluate nutrient loads. The data analysis was performed at 16 monitoring stations from December 2003 to September 2008. Annual and seasonal discharge measured at monitoring stations is affected by rainfall. Hurricanes affected three wet years (2004, 2005, and the latter part of 2008) and resulted in substantially greater discharge than the drought years of 2006, 2007, and the early part of 2008. Rainfall supplies about 50 percent of the water to Lake Okeechobee, discharge from the Kissimmee River supplies about 25 percent, and discharge from tributaries and groundwater seepage along the lake perimeter collectively provide the remaining 25 percent. Annually, tributary discharge from basins located on the west side of the Kissimmee River is about 5 to 6 times greater than that from basins located on the east side. For the purposes of this study, the basins on the east side of the Kissimmee River are called "priority basins" because of elevated phosphorus concentrations, while those on the west side are called "nonpriority" basins. Total annual discharge in the non-priority basins ranged from 245,000 acre-feet (acre-ft) in 2007 to 1,322,000 acre-ft in 2005, while annual discharge from the priority basins ranged from 41,000 acre-ft in 2007 to 219,000 acre-ft in 2005. Mean total phosphorus concentrations ranged from 0.10 to 0.54 milligrams per liter (mg/L) at the 16 tributaries during 2004–2008. Mean concentrations were significantly higher at priority basin sites than at non-priority basin sites, particularly at Arbuckle Creek and C 41A Canal. Concentrations of organic nitrogen plus ammonia ranged from 1.27 to 2.96 mg/L at the 16 tributaries during 2004–2008. Mean concentrations were highest at Fisheating Creek at Lake Placid (a non-priority site), and lowest at Wolff Creek, Taylor Creek near Grassy Island, and Otter Creek (three priority basin sites), and at Arbuckle Creek (a non-priority basin site). Mean concentrations of nitrite plus nitrate ranged from 0.01 to 0.55 mg/L at the 16 tributaries during 2004–2008. Mean concentrations measured in priority basins were significantly higher than those measured in non-priority basins. Nutrient concentrations were substantially lower in the non-priority basins; however, total loads were substantially higher due to discharge that was 5 to 6 times greater than from the priority basins. Total phosphorus, organic nitrogen plus ammonia, and nitrite plus nitrate loads from the non-priority basins were 1.5, 4.5, and 3.5 times greater, respectively, than were loads from the priority basins. In the non-priority basins, total phosphorus loads ranged from 35 metric tons (MT) in 2007 to 247 MT in 2005. In the priority basins, the loads ranged from 18 MT in 2007 to 136 MT in 2005. In the non-priority basins, organic nitrogen plus ammonia loads ranged from 337 MT in 2007 to 2,817 MT in 2005. In the priority basins, organic nitrogen plus ammonia loads ranged from 85 MT in 2007 to 503 MT in 2005. In the non-priority basins, nitrite plus nitrate loads ranged from 34 MT in 2007 to 143 MT in 2005. In the priority basins, nitrite plus nitrate loads ranged from 4 MT in 2007 to 27 MT in 2005.

    We examined the association between perceived discrimination and smoking status and whether psychological distress mediated this relationship in a large, multiethnic sample. We used 2004 through 2008 data from the Behavioral Risk Factor Surveillance System Reactions to Race module to conduct multivariate logistic regression analyses and tests of mediation examining associations between perceived discrimination in health care and workplace settings, psychological distress, and current smoking status. Regardless of race/ethnicity, perceived discrimination was associated with increased odds of current smoking. Psychological distress was also a significant mediator of the discrimination-smoking association. Our results indicate that individuals who report discriminatory treatment in multiple domains may be more likely to smoke, in part, because of the psychological distress associated with such treatment.

  17. Constraining the Magmatic System at Mount St. Helens (2004-2008) Using Bayesian Inversion With Physics-Based Models Including Gas Escape and Crystallization

    Physics-based models of volcanic eruptions track conduit processes as functions of depth and time. When used in inversions, these models permit integration of diverse geological and geophysical data sets to constrain important parameters of magmatic systems. We develop a 1-D steady state conduit model for effusive eruptions including equilibrium crystallization and gas transport through the conduit and compare with the quasi-steady dome growth phase of Mount St. Helens in 2005. Viscosity increase resulting from pressure-dependent crystallization leads to a natural transition from viscous flow to frictional sliding on the conduit margin. Erupted mass flux depends strongly on wall rock and magma permeabilities due to their impact on magma density. Including both lateral and vertical gas transport reveals competing effects that produce nonmonotonic behavior in the mass flux when increasing magma permeability. Using this physics-based model in a Bayesian inversion, we link data sets from Mount St. Helens such as extrusion flux and earthquake depths with petrological data to estimate unknown model parameters, including magma chamber pressure and water content, magma permeability constants, conduit radius, and friction along the conduit walls. Even with this relatively simple model and limited data, we obtain improved constraints on important model parameters. We find that the magma chamber had low (<5 wt %) total volatiles and that the magma permeability scale is well constrained at ~10 –11.4 m 2 to reproduce observed dome rock porosities. Here, compared with previous results, higher magma overpressure and lower wall friction are required to compensate for increased viscous resistance while keeping extrusion rate at the observed value.

  18. Better constraints on the size and volatile content of the Mount St. Helens magma reservoir following the end of the 2004-2008 eruption

    The October 2004-January 2008 eruption of Mount St. Helens produced about 93 million cubic meters dense-rock equivalent (DRE) lava at a continuous rate that decreased monotonically from ~6 m3 s-1 to zero over its duration. From late October 2004 through the end of the eruption, continuous GPS stations around the mountain recorded inward deflation at a rate that dropped monotonically below the noise level by early 2007. The geodetic signal is consistent with a volume change Δ Vc of ~16-25M m3 in an ellipsoidal reservoir of volume Vc centered at ~9-14 km depth beneath the crater. Throughout the eruption we used physically based models to extrapolate trends in lava-dome volume and deflation, and to forecast the duration and final erupted volume, Ve, using assumed or geologically constrained values of Vc, average recharge rate R into the reservoir, and compressibilities of magma (Km = ( 1/ρ m )( ∂ ρ m /∂ p )) and of the reservoir (Kc = ( 1/Vc )( ∂ Vc /∂ p )), where ρ m is magma density and p is pressure). Curves that neglected recharge consistently under-predicted both the final duration and volume, while those that assumed a constant recharge rate predicted indefinite duration and volume. The fact that the eruption ended several months after deflation stopped suggests that the long-term average recharge was close to zero, or at least much less than the average eruption rate. The discrepancy between Ve (93M m3) and Δ VC (16-25M m3) can be accounted for by the elastic relation Ve /Δ Vc = ( 1 + Km /Kc ), with Km = 3 - 4 × 10- 10 Pa-1 calculated for reservoir magma with 1- 1.5% bubbles (constrained from gas studies of the erupted lava), and Kc = 1.1 - 1.5 × 10 - 10 Pa-1. Assuming that the pressure drop dp in the reservoir was only slightly greater than the ~5 MPa increase in pressure at the 2004 vent elevation due to growth of the 220-m-high lava dome, the elastic relation Ve = VC dp( Kc + Km ) suggests that the eruption could have been fed by a reservoir of volume Vc =20-30 km3. This is substantially larger than the 10-20 km3 reservoir size inferred from our earlier calculations that assumed 0.5-1.5 m3/s average recharge rate. A smaller, 10-20 km3 reservoir could have fed this eruption if it contained magma with substantially more bubbles (2-4 vol %) and higher compressibility (5-9× 10-10 Pa-1) than suggested by gas studies; more pressure drop (8-12 MPa); or was fed by some recharge. Theoretically, the effusion rate would have decreased exponentially with time if the reservoir had been fed from an elastically relaxing magma body through a conduit in which the flow rate varied linearly with reservoir pressure. Instead, the measured effusion rate was roughly constant during the second and third years of the eruption. Possible explanations are (a) changes in vent geometry with time; (b) an effusion rate controlled by rate-strengthening frictional properties on the conduit walls; (c) gradual breakage of septa within the magma reservoir, integrating different parts of the reservoir into a single larger mechanical body over time; or (d) transient recharge. Now that geodetic monitoring of Mount St. Helens includes additional Plate Boundary Observatory GPS stations, tiltmeters, and borehole strainmeters, it may be possible to distinguish among these mechanisms should the eruption resume.

    We analyze a group of 6073 low-frequency earthquakes recorded during a week-long temporary deployment of broadband seismometers at distances of less than 3 km from the crater at Mount St. Helens in September of 2006. We estimate the seismic moment (M0) and spectral corner frequency (f0) using a spectral ratio approach for events with a high signal-to-noise (SNR) ratio that have a cross-correlation coefficient of 0.8 or greater with at least five other events. A cluster analysis of cross-correlation values indicates that the group of 421 events meeting the SNR and cross-correlation criteria forms eight event families that exhibit largely self-similar scaling. We estimate the M0 and f0 values of the 421 events and calculate their static stress drop and scaled energy (ER/M0) values. The estimated values suggest self-similar scaling within families, as well as between five of eight families (i.e.,  and  constant). We speculate that differences in scaled energy values for the two families with variable scaling may result from a lack of resolution in the velocity model. The observation of self-similar scaling is the first of its kind for such a large group of low-frequency volcanic tectonic events occurring during a single active dome extrusion eruption.

    Physics-based models of volcanic eruptions can directly link magmatic processes with diverse, time-varying geophysical observations, and when used in an inverse procedure make it possible to bring all available information to bear on estimating properties of the volcanic system. We develop a technique for inverting geodetic, extrusive flux, and other types of data using a physics-based model of an effusive silicic volcanic eruption to estimate the geometry, pressure, depth, and volatile content of a magma chamber, and properties of the conduit linking the chamber to the surface. A Bayesian inverse formulation makes it possible to easily incorporate independent information into the inversion, such as petrologic estimates of melt water content, and yields probabilistic estimates for model parameters and other properties of the volcano. Probability distributions are sampled using a Markov-Chain Monte Carlo algorithm. We apply the technique using GPS and extrusion data from the 2004–2008 eruption of Mount St. Helens. In contrast to more traditional inversions such as those involving geodetic data alone in combination with kinematic forward models, this technique is able to provide constraint on properties of the magma, including its volatile content, and on the absolute volume and pressure of the magma chamber. Results suggest a large chamber of >40 km3 with a centroid depth of 11–18 km and a dissolved water content at the top of the chamber of 2.6–4.9 wt%.

    Background and Objectives: The examination of the research attractions in developed counties, and deficiencies and constraints in conducting researches can reveal invaluable implications. The researches carried out in recent decades are indicative of the fact that there have always been major constraints during the research conduction. Those countries which aspire to compete in the world should remove all the constraints and barriers, and attract the necessary attention on researches. Thus, the current study was intended to find the problems and limitations, and offer the needed interventions so as to overcome those problems.

    Methods: This study was a quasi-experimental (pre and post one. The participants of the study included those faculty members and researchers who had conducted at least a project as an administrator or a major contributor before and after intervention. In order to gather data, a self-designed questionnaire was filled in two phases; before and after the interventions. The questionnaire included demographics and information about research problems in the four areas of Research Project Preparation (RPP, Research Project Conduct (RPC, Administrative-Management and Personal Problems. Descriptive statistics and various statistical procedures tests were utilized to analyze the data.

    Results: The findings revealed that the mean of the magnitude of the research problems in RPP, RPC, administrative management and personal problems was a significant difference (P<0.001 before and after intervention. In RPP, lack of beneficial database bank in university, in RPC lack of budget, in Administrative-Management lack of knowledge accountant about corresponding activity and in Personal Problems lack of enough motivation for research were all having the highest intensity. Thus, after intervention the magnitude of the problem was reduced.

    Full Text Available AbstractBackground and Objectives: The examination of the research attractions in developed counties, and deficiencies and constraints in conducting researches can reveal invaluable implications. The researches carried out in recent decades are indicative of the fact that there have always been major constraints during the research conduction. Those countries which aspire to compete in the world should remove all the constraints and barriers, and attract the necessary attention on researches. Thus, the current study was intended to find the problems and limitations, and offer the needed interventions so as to overcome those problems.Methods: This study was a quasi-experimental (pre and post one. The participants of the study included those faculty members and researchers who had conducted at least a project as an administrator or a major contributor before and after intervention. In order to gather data, a self-designed questionnaire was filled in two phases; before and after the interventions. The questionnaire included demographics and information about research problems in the four areas of Research Project Preparation (RPP, Research Project Conduct (RPC, Administrative-Management and Personal Problems. Descriptive statistics and various statistical procedures tests were utilized to analyze the data.Results: The findings revealed that the mean of the magnitude of the research problems in RPP, RPC, administrative management and personal problems was a significant difference (P<0.001 before and after intervention. In RPP, lack of beneficial database bank in university, in RPC lack of budget, in Administrative-Management lack of knowledge accountant about corresponding activity and in Personal Problems lack of enough motivation for research were all having the highest intensity. Thus, after intervention the magnitude of the problem was reduced. Conclusion: In conclusion, it seems that bureaucratic rules, shortage of research budget, heavy work load, lack of motivation, and personal skills are the reasons which hinder doing research activities. But the findings of this current study reveal that through reforming the administrative-management procedures and appropriate planning with regard to the current problems we can overcome the barriers and ameliorate the magnitude of the problems.Keywords: Intervention Studies; Organization and Administration; Operations Research; Research Personnel; Faculty; Universities; Qom, Iran.

    Full Text Available The asymmetric unit of the title compound, C20H34O2, contains two crystallographically independent molecules (1 and 2 with similar conformations. In both molecules, the cyclohexane rings adopt a chair conformation, while the oxane rings are also puckered. In the crystal, O—H...O hydrogen bonds connect adjacent molecules, forming C(6 helical chains located around a 21 screw axis and running along the crystallographic a axis. The packing of these chains is governed only by van der Waals interactions. Semi-empirical PM3 quantum chemical calculations are in a satisfactory agreement with the structural results of the X-ray structure analysis. The absolute structure was indeterminate in the present experiment.

    Niche distribution models accurately predict the potential distribution range of invasive plants into new habitats based on their climatic requirements in the native regions. However, these models usually ignore the marginal habitats which can limit the distribution of exotic plants. We therefore tested the seedling survival, growth and nutrient acquisition capabilities of two co-occurring invasive vines [Persicaria perfoliata (L.) H. Gross and Sicyos angulatus L.] in three different manipulative greenhouse experiments to infer their range expansion potential to marginal habitats in Turkey. First experiment included five different moisture availability regimes (100, 75, 50, 25 and 12.5% available water), second experiment consisted of four different salinity levels (0, 3, 6 and 12 dSm-1 soil salinity) and third experiment had four different soil textures (clay-1, clay-2, sandy loam and silt-clay-loam). Seedling mortality was only observed under extreme moisture deficiency in both plant species, while most of the transplanted seedlings of both species did not survive under 6 and 12 dSm-1 salinity levels. Soil textures had no effect on seedling survival. POLPE better tolerated low moisture availability and high salinity compared to SIYAN. Biomass production in both plant species was linearly reduced with increasing salinity and moisture deficiency. SIYAN invested more resources towards shoot, accumulated higher K and P, whereas POLPE maintained higher root-to-shoot ratio under all experimental conditions. Both plant species employed different strategies to cope with adverse environmental conditions, but failed to persist under high soil salinity and moisture deficiency. Our study suggest that both plant species have limited potential of range expansion to marginal habitats and will be limited to moist and humid areas only. Therefore, further research activities should be concentrated in these regions to develop effective management strategies against both species.

La Ley estableció que la contratación de los PCD sería de carácter indefinido y con dedicación a tiempo completo, determinó que dichos profesores tenían plena capacidad docente e investigadora, reconoció su condición de elegibles para los órganos unipersonales de gobierno (salvo para el cargo de rector, les atribuyó voto ponderado en la constitución del claustro universitario y en la elección de rector y, mediante modificación de la Ley General de Sanidad, determinó que podría establecerse vinculación de plazas asistenciales con plazas de PCD. Por lo que respecta a los requisitos para acceder a una plaza de PCD, la LOMLOU suprimió la necesidad de acreditar tres años de actividad docente e investigadora, establecida por la LOU, pero mantuvo como requisito una evaluación positiva por parte de un órgano externo (acreditación. En este artículo se analizan comparativamente los procesos de acreditación desarrollados por la Agencia Nacional de Evaluación de la Calidad y Acreditación (ANECA y por los órganos de evaluación establecidos por las diversas comunidades autónomas, así como los concursos de acceso a las plazas convocadas por las universidades.

Determined that these professors had full autonomy in teaching and research, recognized their condition of eligible for the individual organs of government (save for the charge of Rector and attributed them balanced vote in the University Cloister and in the election of Rector. Furthermore, by means of modification of the General Law of Health, the LOMLOU determined that could be established linking of welfare positions with positions of PCD. For which it concerns to the requirements to achieve to a position of PCD, the Law suppressed the need to accredit three years of teaching and researcher, established by the previous Law of Universities; but maintained as requirement a positive evaluation of teaching and research by an external assessment body (accreditation.

    We examined whether the relative importance of facilitation and competition effects by an unpalatable perennial ( Urtica thunbergiana) on a palatable annual ( Persicaria longiseta) change with the spatial distance between them in a long-term deer-grazing habitat. Survivorship, growth, size, and fecundity of Persicaria were recorded at 1-2-month intervals during growing seasons in 2 successive years and were compared among individuals located in different positions relative to the canopy of Urtica: at the centre, internal edge, external edge, and far from the canopy. Survivorship of Persicaria was significantly higher at the centre of the Urtica canopy than outside the canopy early in the growing season in both years. No significant differences in Persicaria growth were observed among the four positions in most periods, except in one when growth was significantly higher at the centre, internal, and external edges of the canopy compared to outside the canopy. We found spatial shifts in the net effects of Urtica on Persicaria fecundity, from positive effects under the canopy centre to negative effects under the external edge of the canopy in the first year, and from negative effects under the centre to positive effects under the external edge in the second year. These results demonstrate that the relative importance of positive and negative effects of Urtica on Persicaria vary temporally within and among years and spatially around a single Urtica plant. Spatiotemporal variation in plant interactions may be attributable to annual and seasonal variation in vegetation productivity and grazing pressure.

    The complete ITS (internal transcribed spacer) region coding the ITS1, the ITS2 and the 5.8S rDNA was amplified by polymerase chain reaction from two strains of Gilbertella persicaria, six strains in the Mucoraceae (Mucor piriformis, M. rouxii, M. circinelloides, Rhizomucor miehei, R. pusillus and R. tauricus) and four strains representing three species of the Choanephoraceae (Blakeslea trispora, Choanephora infundibulifera and Poitrasia circinans). Sequences of the amplified DNA fragments were determined and analysed. G. persicaria belongs to the monogeneric family (Gilbertellaceae), however, originally it was described as Choanephora persicaria. The goal of this study was to reveal the phylogenetic relationship among fungi belonging to Gilbertellaceae, Choanephoraceae and Mucoraceae. Our results support that the "intermediate" position of this family is between Choanephoraceae and Mucoraceae.

    Seeds are either stored in a soil seed bank or retained on maternal plants until they are released (aerial seed bank). Though there are extensive studies on the germination requirements of seeds in soil banks of saline habitats, studies conducted for halophytes with aerial seed banks are rare. We assessed the impact of aerial and room-temperature storages on the light and temperature requirements during germination in two small-seeded halophytes: Halocnmum strobilaceum having a short-term aerial seed bank (less than one year) and Halopeplis perfoliata having a longer term aerial seed bank (up to two years). Seed storage in the aerial bank reduced the germination in H. strobilaceum, but either increased it (5-months storage) or had no effect (17-months storage) in H. perfoliata. Seeds of both species that were stored in aerial bank germinated to higher percentages in light than in darkness, indicating that considerable portions of the seed populations are light sensitive. Seeds of H. perfoliata attained less than 5.0 percentage germination in darkness at higher temperatures, compared to more than 90.0 percentage in light. The results support the hypothesis that the aerial seed bank is an adaptive strategy for survival in the saline habitats of the two species. (author)

  13. Contrasting patterns of transgenerational plasticity in ecologically distinct congeners.

    Science.gov (United States)

    Sultan, Sonia E; Barton, Kasey; Wilczek, Amity M

    2009-07-01

    Stressful parental environments can influence offspring size and development either adaptively or maladaptively, yet little is known about species' differences in this complex aspect of phenotypic plasticity. We performed a reciprocal split-brood experiment to compare transgenerational plasticity in response to drought stress in two closely related annual plant species. We raised inbred replicate parent plants of eight genotypes per species in dry vs. moist soil to generate offspring of each genetic line that differed only in parental environment, then monitored seedling development in both dry and moist conditions. Individuals of the two species expressed contrasting patterns of transgenerational plasticity for traits important to seedling drought tolerance. In Polygonum persicaria, a weedy generalist found in moist, dry, and variably dry sites, drought-stressed plants produced offspring with longer and more rapidly extending root systems and greater biomass when growing in dry soil. In contrast, in P. hydropiper, a non-weedy congener restricted to moist habitats, the offspring of drought-stressed parents had reduced root system development and seedling biomass in dry soil. In P. persicaria, transgenerational and immediate adaptive plasticity combined to produce drought-adapted seedling phenotypes. These results make clear that characteristic patterns of transgenerational plasticity can contribute to ecological diversity among species.

  14. VEGETATION BEHAVIOR AND ITS HABITAT REGION AGAINST FLOOD FLOW IN URBAN STREAMS

    Directory of Open Access Journals (Sweden)

    IL-KI CHOI

    2013-06-01

    Full Text Available Hydraulic effects on the vegetation behavior and on its habitat region against flood flow in the urban streams were analysed in this paper. Vegetation behavior was classified into stable, recovered, damaged and swept away stages. Criteria between recovered and damaged status were determined by the bending angle of the aquatic plants. Aquatic plants whose bending angle is lower than 30~50 degree is recovered, but they were damaged and cannot be recovered when the bending angle is higher than 30~50 degree. Phragmites japonica was inhabited in the hydraulic condition of high Froude number which shows that it was inhabited in the upstream reaches. Phragmites communis was inhabited in the relatively low Froude number compared with Phragmites japonica. This shows that it was inhabited in the downstream reaches. Persicaria blumei was found in the relatively wide range of flow velocity and flow depth, which shows that it was inhabited in the middle and downstream reaches. Criterion on the vegetation behavior of Persicaria thunbergii was not clear, which implies that it may be affected by the flow turbulence rather than flow velocity and flow depth.

    Full Text Available A review of the genera Othonna and Senecio undertaken for the forthcoming Greater Cape plants 2: Namaqualand-southern Namib and western Karoo (Manning in prep. led to a re-examination of the taxonomic status of several species. This was facilitated by the recent availability of high-resolution digital images on the Aluka website (www.aluka.org of the Drege isotypes in the Paris Herbarium that formed the basis of many species described by De Candolle in his Prodromus systematis naturalis regni vegetabilis. These images made it possible to identify several names whose application had remained uncertain until now. Each case is briefly discussed, with citation of additional relevant herbarium specimens. The following species are reduced to synonomy: O. incisa Harv. is included in O. rosea Harv.; O. spektakelensis Compton and O. zeyheri Sond. ex Harv. are included in O. retrorsa DC.; S. maydae Merxm. is included in S. albopunctatus Bolus, which is now considered to include forms with radiate and discoid capitula; S. cakilefolius DC. is included in  O. arenarius Thunb.; S. pearsonii Hutch, is included in O. aspertdus DC.; S. parvifolius DC. is included in S. carroensis DC.; S. eriobasis DC. is included in S. erosus L.f.; and S. lobelioides DC. is included in S. flavus (Decne.

  16. The evaluation of the trends of Polish farms incomes in the FADN regions after the integration with the EU

    2011-01-01

    Full Text Available The main aim of this article was to identify trends regarding income changes in the period of 2004-2008 in Poland between the regions of FADN. In 2004-2008 we noticed the processes of convergence in range of income situation of farms among the FADN regions. It was noticed that the convergence of beta type and the sigma were in place. This situation appears for general group of farms, as well as in farms with mixed production. Although, exclusion of the subsidies would initiate the divergence processes. This means that direct payments make up a kind of catalytic situation in range of levelling incomes situation in farms among these regions. We could initially signal that instruments of the CAP favour getting differences of incomes smaller in spatial range, what would indicate some kind of strategy in the aims of the EU policy with reference to sustainable growth in spatial range.

    The anterior mesenteric arteries of 138 horses slaughtered in southern Queensland were examined for the presence of S. vulgaris larvae. Seasonal differences were noted in the size of arterial populations of this parasite, with higher mean monthly numbers of worms per horse occurring in winter. There was an equally high incidence of severe verminous arteritis during the winter months of June, July and August, compared to arteries examined during the warmer months, when there were smaller numbers of larvae. It was concluded that more infective larvae were available on pasture during the warmer months, with subsequently large arterial populations some 3 to 4 months later. The parasite was encountered in 121 arteries (88%). The prevalence of adult helminths in the caeca of the same group of horses was S. vulgaris 88%; S. equinus 70%; S. edentatus 18%; Triodontophorus spp. 23%; A. perfoliata 62%. The overall prevalence of S. vulgaris was 93%, when the results of arterial and caecal observations were combined.

    Research carried out during the last 4 years (1996-1999) of an 11-year study of the prevalence of internal parasites naturally transmitted to horse foals born on the same pasture on a farm in central Kentucky is presented here. Horses in this herd were not treated with any antiparasitic compound for over 20 years except for a replacement stallion in 1994. A total of 22 species, including 12 species of small strongyles, were recovered in the 4-year period. Transmission patterns of all species (n=35) of endoparasites recovered are compared for the 11-year study. Some of the changes were an increase in number of Thelazia lacrymalis and Anoplocephala perfoliata and a decrease in Gasterophilus intestinalis, Parascaris equorum, and Strongylus vulgaris. Clinical problems associated with parasitism were not observed in any of the 92 foals in the long-term investigation.

    Full Text Available The present research is a continuation of studies conducted periodically over 40 years on transmission of natural infections of internal parasites in the same horse herd on pasture (Field 10 on a farm in Central Kentucky. It included 12 mixed light horse foals born in 2013 and euthanatized between July, 2013 and April, 2014 for collection of internal parasites. Parasites found: Gasterophilus intestinalis, Strongyloides westeri, Parascaris equorum, Anoplocephala perfoliata, small strongyles (cyathostomes, Strongylus vulgaris, Strongylus edentatus and Thelazia lacrymalis. Prevalence generally was related to age of the foals. Overall prevalence and number of specimens were lower than in earlier studies except for P. equorum. There were 15 species (much fewer than previously of small strongyles found and recorded by location in the large intestines. All stages of small strongyles encysted in the mucosa of the large intestine were recovered by artificial digestion and in significantly lower numbers in older foals

    Full Text Available Natural habitats on the territory of Novi Sad are almost fully destroyed today, as well as their characteristic plant taxa. The reason for disappearance of natural habitats is the development of suburban communities, which is an irreversible process. Plant taxa, specific for wet, salty, and sandy ecosystems grew on those habitats twenty years ago and earlier. This paper presents the overview of 9 taxa (Suaeda maritima subsp. maritima, Androsace elongata subsp. elongata, Cirsium boujartii subsp. boujartii, Aster sedifolius subsp. canus, Blackstonia perfoliata subsp. serotina, Plantago maritima subsp. maritima, Salvia nutans, Allium angulosum, and Typha schuttleworthii. These taxa presented integral parts of autochthonous flora of Novi Sad. Since some of these taxa were found in the field 21 years ago and some even 93 years ago, they are extinct from the flora of Novi Sad.

    Full Text Available With the aim of studying the endoparasite fauna of horses from the Formiga city, located in center-west region of the state of Minas Gerais, 25 animals that were naturally infected with helminths were evaluated. By means of parasitological necropsies, different endoparasites were found. The subfamily Cyathostominae presented the highest incidence, followed by Trichostrongylus axei, Oxyuris equi, Triodontophorus serratus, Strongyloides westeri, Strongylus edentatus, Habronema muscae, Parascaris equorum, Probstmayria vivipara, Strongylus vulgaris, Gasterophilus nasalis, Anoplocephala magna and Anoplocephala perfoliata. In the present study, if the species Probstmayria vivipara was not considered in the prevalence, the frequency of Cyathostominae was equivalent to 94.85%. The results obtained in this study allowed us to detect and identify different species of helminths in horses, and confirmed the high incidence of nematodes belonging to the subfamily Cyathostominae in the center-west region of Minas Gerais.

    Full Text Available The aim of the field study performed in 2006 was to investigate the occurrence and distribution of intestinal helminths in horses based on pre-treatment faecal egg counts. In total, 948 horses bred on 37 farms were tested. Thirty six (97.2% farms tested were positive for cyathostomins; horses in 9 (24.3%, 6 (16.2% and 1 (2.7% different herds tested were positive for Parascaris equorum, Anoplocephala perfoliata and Strongyloides westeri, respectively. In 21 herds, 344 horses with values exceeding 100 eggs per gram were included in the trial for the presence of drug resistant cyathostomins by a faecal egg count reduction test. Horses were treated orally with recommended doses of fenbendazole and ivermectin. Resistance to fenbendazole was detected on 20 farms (95.24% with values of faecal egg count reduction test ranging from 0 to 90%. Ivermectin remained effective in all tested herds with the value of faecal egg count reduction test 96–100%. In autumn 2008, 178 horses on 10 farms were examined. Of these, only seven horses tested were negative for cyathostomins. One farm was tested positively for Anoplocephala perfoliata, and one for Parascaris equorum. In spring 2009, six farms were examined, four of which were the same farms as in 2006. We found a decreased number of eggs per gram in all horses, but an increase in benzimidazole resistance, which was found in 5 farms out of 6 (faecal egg count reduction test 15.2–84.6%. This is the first wide survey in horses from the Czech Republic. Based on this study, we can conclude that benzimidazole resistant cyathostomins in horses are widespread but ivermectin is still fully effective.

    A population survey of phytoseiid mites and spider mites was conducted on peach leaves and wild plants in Japanese peach orchards having different pesticide practices. The phytoseiid mite species composition on peach leaves and wild plants, as estimated using quantitative sequencing, changed during the survey period. Moreover, it varied among study sites. The phytoseiid mite species compositions were similar between peach leaves and some wild plants, such as Veronica persica, Paederia foetida, Persicaria longiseta, and Oxalis corniculata with larger quantities of phytoseiid mites, especially after mid-summer. A PCR-based method to detect the ribosomal ITS sequences of Tetranychus kanzawai and Panonychus mori from phytoseiid mites was developed. Results showed that Euseius sojaensis (specialized pollen feeder/generalist predator) uses both spider mites as prey in the field.

  16. Pulsed growth of fungal hyphal tips.

    1994-12-06

    Somatic fungal hyphae are generally assumed to elongate at steady linear rates when grown under constant environmental conditions with ample nutrients. However, patterns of pulsed hyphal elongation were detected during apparent steady growth of hyphal tips in fungi from several major taxonomic groups (Oomycetes, Pythium aphanidermatum and Saprolegnia ferax; Zygomycetes, Gilbertella persicaria; Deuteromycetes, Trichoderma viride; Ascomycetes, Neurospora crassa and Fusarium culmorum; Basidiomycetes, Rhizoctonia solani). Growing hyphal tips were recorded with video-enhanced phase-contrast microscopy at high magnification, and digital images were measured at very short time intervals (1-5 s). In all fungi tested, the hyphal elongation rate was never perfectly steady but fluctuated continuously with alternating periods of fast and slow growth at more or less regular intervals. Pulsed growth was observed in fungi differing in cell diameter, overall growth rate, taxonomic position, and presence and pattern of Spitzenkörper organization, suggesting that this is a general phenomenon. Frequency and amplitude of the pulses varied among the test organisms. T. viride and N. crassa showed the most frequent pulses (average of 13-14 per min), and F. culmorum the least frequent (2.7 per min). Average pulse amplitude varied from 0.012 microns/s for F. culmorum to 0.068 microns/s for G. persicaria. In F. culmorum and T. viride, the fast phase of the growth pulses was correlated with the merger of satellite Spitzenkörper with the main Spitzenkörper. These findings are consistent with a causal relationship between fluctuations in the overall rate of secretory vesicle delivery/discharge at the hyphal apex and the fluctuations in hyphal elongation rate.

  17. Field-based insights to the evolution of specialization: plasticity and fitness across habitats in a specialist/generalist species pair.

    Griffith, Timothy; Sultan, Sonia E

    2012-04-01

    Factors promoting the evolution of specialists versus generalists have been little studied in ecological context. In a large-scale comparative field experiment, we studied genotypes from naturally evolved populations of a closely related generalist/specialist species pair (Polygonum persicaria and P. hydropiper), reciprocally transplanting replicates of multiple lines into open and partially shaded sites where the species naturally co-occur. We measured relative fitness, individual plasticity, herbivory, and genetic variance expressed in the contrasting light habitats at both low and high densities. Fitness data confirmed that the putative specialist out-performed the generalist in only one environment, the favorable full sun/low-density environment to which it is largely restricted in nature, while the generalist had higher lifetime reproduction in both canopy and dense neighbor shade. The generalist, P. persicaria, also expressed greater adaptive plasticity for biomass allocation and leaf size in shaded conditions than the specialist. We found no evidence that the ecological specialization of P. hydropiper reflects either genetically based fitness trade-offs or maintenance costs of plasticity, two types of genetic constraint often invoked to prevent the evolution of broadly adaptive genotypes. However, the patterns of fitness variance and herbivore damage revealed how release from herbivory in a new range can cause an introduced species to evolve as a specialist in that range, a surprising finding with important implications for invasion biology. Patterns of fitness variance between and within sites are also consistent with a possible role for the process of mutation accumulation (in this case, mutations affecting shade-expressed phenotypes) in the evolution and/or maintenance of specialization in P. hydropiper.

    Full Text Available Os eqüinos apresentam uma grande variedade de parasitas em sua fauna helmíntica, e algumas espécies/gêneros são de relevada importância, como: Parascaris equorum, Anoplocephala perfoliata, Oxyuris equi, Cyathostomum spp. e Strongylus spp. O controle destas infecções depende principalmente da utilização de produtos antiparasitários de forma supressiva ou estratégica e, em menor escala, de forma curativa. O tratamento supressivo é o fator mais importante na promoção da seleção de organismos resistentes, prejudicando a sustentabilidade de qualquer programa sanitário. As formas de detecção da resistência parasitária são onerosas e as mais comuns expressam resultados imprecisos. Entretanto, estas técnicas servem para monitorar a evolução e determinar os organismos envolvidos. A combinação de drogas é uma ferramenta que deve ser utilizada com muita cautela, pois esta alternativa não garante uma redução significativa de organismos resistentes aos compostos envolvidos. O objetivo deste artigo é apresentar formas de planejamento que auxiliem a melhorar a condição sanitária, o bem-estar dos animais e preserve o efeito tóxico dos produtos antiparasitários.Equines harbour a variety of parasitic organisms on their helminth fauna and there are a few species/genus of interest, such as: Parascaris equorum, Anoplocephala perfoliata, Oxyuris equi, Cyathostomum spp. and Strongylus spp. The control of these infections relies mostly on the suppressive or strategic usage of antiparasitic compounds, and to a less extent on curative/salvage treatments. Suppressive treatment is the most important factor regarding the selection of resistant organisms, causing the impairment of sanitary programs. Detection methods of parasite resistance are expensive and the most common ones express variable results.

    In industrial countries, a number of factors put indigenous peoples at increased risk of HIV infection. National surveillance data between 1999 and 2008 provided diagnoses for Aboriginal and Torres Strait Islanders (Australia), First Nations, Inuit and Métis (Canada excluding Ontario and Quebec) and Māori (New Zealand). Each country provided similar data for a non-indigenous comparison population. Direct standardisation used the 2001 Canadian Aboriginal male population for comparison of five-year diagnosis rates in 1999-2003 and 2004-2008. Using the general population as denominators, we report diagnosis ratios for presumed heterosexual transmission, men who have sex with men (MSM) and intravenous drug users (IDU). Age standardised HIV diagnosis rates in indigenous peoples in Canada in 2004-2008 (178.1 and 178.4/100 000 for men and women respectively) were higher than in Australia (48.5 and 12.9/100 000) and New Zealand (41.9 and 4.3/100 000). Higher HIV diagnosis rates related to heterosexual contact among Aboriginal peoples, especially women, in Canada confirm a widening epidemic beyond the conventional risk groups. This potential of a generalised epidemic requires urgent attention in Aboriginal communities; available evidence can inform policy and action by all stakeholders. Although less striking in Australia and New Zealand, these findings may be relevant to indigenous peoples in other countries.

    Full Text Available Out of 92 donkeys examined for gastrointestinal parasites, 90 animals were found infected by one or more gastrointestinal parasites with an overall prevalence rate of 97.78%. The distributions of the recovered parasites in the different parts of the body were as follows: stomach, 92.4%, small intestine, 19.6%, caecum, 88%, colon, 80.4%, rectum, 73.9%, and cranial mesenteric artery, 64.1%. A significant difference was found between mean parasite counts and seasons. Hot wet season had higher mean parasites count (5411.5±1694.4 in comparison with hot dry (1795.9±399.6 and cool dry (1719.9±522.4 seasons. Although there was no significant difference between age and mean parasite count, animals more than four years old had high mean count (3361.3±921.8 in comparison with 2330±744.3 and 2030.2±873.1 for young and adults animals, respectively. No significant positive or negative correlation was found between total parasite counts of infected animals and any of the climatic factors.

    Full Text Available Bistorta macrophylla, B.vaccinifolia and Persicaria polystachya are used for the treatment and prevention of many ailments including tuberculosis, inflammation, pyretic, fever, flue, lungs disorders, diarrhea, vomiting, arthritis, gout, kidney stones or hyperacidity and hypertension. This study was aimed to evaluate the possible in vitro antioxidant activity and phytochemical screening of B. macrophylla, B.vaccinifolia and P. polystachya. The results of antioxidant activity study of B. macrophylla showed maximum activity in the methanolic extracts at different concentration of 20, 40, 60, 80 and 100 µg/ml. The percent inhibition of writhing response by the extract was 36.18%, 44.72%, 59.21%. 67.08% and 83.39% respectively. In the present work a potent anti-oxidant activity of methanolic extract of the whole plants of B. macrophylla were demonstrated, validating the ethno pharmacological claims. These experimental findings would further establish the scientific basis of the traditional uses of the plant in the management of different conditions as well as control of different disease.

    Full Text Available The paper presents the results of research of plant macrofossils from the grain deposit deriving from the 18th/19th centuries. The analysed material included 24760 diaspores representing 73 taxa. The majority were cultivated cereal crop species, and there was also abundance of accompanying segetal weed species. About 95% of the gathered crop material was Secale cereale. Another important crop was Hordeum vulgare and there were also some remains of Avena sativa, Triticum aestivum, Fagopyrum esculentum. Cannabis sativa and Linum usitatissimum were found as well. Weeds competing with these crops were, among others, the following species: Agrostemma githago, Raphanus raphanistrum, Apera spica-venti, Bromus secalinus, Centaurea cyanus, Spergula arvensis, Thlaspi arvense, Viola arvensis/tricolor, Fallopia convolvulus, Polygonum persicaria, Mentha arvensis, Anthemis arvensis, Papaver rhoeas, Rumex acetosella, Scleranthus annuus, Aphanes arvensis, Setaria pumila, Setaria viridis/verticilata. Extremely large presence of wild plant diaspores in the material allowed conducting economic and environmental interpretations. Reconstruction methods applied, used primarily in the case of macroremains from granaries, were fully applicable to the analysed plant residues. Weed species composition in the analysed material showed that they were mostly typical for the main winter crop. Some amount of species typical for other habitats were also found and they probably came from the near-by rye field. The presence of perennial diaspores indicated that the field was probably set aside

    This study evaluates the effects of the triazine herbicide simazine in an outdoor pond microcosm test system that contained two submerged rooted species (Myriophyllum spicatum and Elodea canadensis) and two emergent rooted species (Persicaria amphibia and Glyceria maxima) over a period of 84 days. Simazine was applied to the microcosms at nominal concentrations of 0.05, 0.5 and 5 mg/L. General biological endpoints and physiological endpoints were used to evaluate herbicide toxicity on macrophytes and the algae developing naturally in the system. Concentration-related responses of macrophytes and algae were obtained for the endpoints selected, resulting in a no observed ecologically adverse effect concentration (NOEAEC) at simazine concentrations of 0.05 mg active ingredient/L after 84 days. E. canadensis was the most negatively affected species based on length increase, which was consistently a very sensitive parameter for all macrophytes. The experimental design presented might constitute a suitable alternative to conventional laboratory single-species testing. - Simazine at concentrations of 0.05 mg/L does not cause long-term negative effects to aquatic macrophytes or algae.

    Environmental stresses experienced by individual parents can influence offspring phenotypes in ways that enhance survival under similar conditions. Although such adaptive transgenerational plasticity is well documented, its transmission mechanisms are generally unknown. One possible mechanism is environmentally induced DNA methylation changes. We tested this hypothesis in the annual plant Polygonum persicaria, a species known to express adaptive transgenerational plasticity in response to parental drought stress. Replicate plants of 12 genetic lines (sampled from natural populations) were grown in dry versus moist soil. Their offspring were exposed to the demethylating agent zebularine or to control conditions during germination and then grown in dry soil. Under control germination conditions, the offspring of drought-stressed parents grew longer root systems and attained greater biomass compared with offspring of well-watered parents of the same genetic lines. Demethylation removed these adaptive developmental effects of parental drought, but did not significantly alter phenotypic expression in offspring of well-watered parents. The effect of demethylation on the expression of the parental drought effect varied among genetic lines. Differential seed provisioning did not contribute to the effect of parental drought on offspring phenotypes. These results demonstrate that DNA methylation can mediate adaptive, genotype-specific effects of parental stress on offspring phenotypes. © 2016 The Author(s).

Concentration of H2O2, MDA and TAA were higher in the three plants collected from polluted sites as compared with those of plants grown in control Nile site (Site1. The opposite was true for Asc A, SS and SP where their concentrations reduced significantly in response to water pollution. Leaf membrane was more damaged (high injury % in plants exposed to wastes from different sources than in plants growing at control site. The results of this study indicated that water pollution reduced the oxidative defense abilities in the three plants through reduction of Asc A activities, enhancement of H2O2 production and increasing MDA accumulation. In addition it impaired the metabolic activity through lowering the SS and SP contents and enhancement of TAA accumulation and increase membrane injury. The over production of hydrogen peroxide by the studied aquatic plants under water pollution could be used as an oxygen source needed to oxidize the more resistant organic and inorganic pollutants and used for pollution control and municipal and industrial wastewater treatment.

    Full Text Available Isoprenoids are a large and diverse group of metabolites with interesting properties such as flavour, fragrance and therapeutic properties. They are produced via two pathways, the mevalonate pathway or the 2-C-methyl-D-erythritol-4-phosphate (MEP pathway. While plants are the richest source of isoprenoids, they are not the most efficient producers. Escherichia coli and yeasts have been extensively studied as heterologous hosts for plant isoprenoids production. In the current study, we describe the usage of the food grade Lactococcus lactis as a potential heterologous host for the production of sesquiterpenes from a local herbaceous Malaysian plant, Persicaria minor (synonym Polygonum minus. A sesquiterpene synthase gene from P. minor was successfully cloned and expressed in L. lactis. The expressed protein was identified to be a β-sesquiphellandrene synthase as it was demonstrated to be functional in producing β-sesquiphellandrene at 85.4% of the total sesquiterpenes produced based on in vitro enzymatic assays. The recombinant L. lactis strain developed in this study was also capable of producing β-sesquiphellandrene in vivo without exogenous substrates supplementation. In addition, overexpression of the strain's endogenous 3-hydroxy-3-methylglutaryl coenzyme-A reductase (HMGR, an established rate-limiting enzyme in the eukaryotic mevalonate pathway, increased the production level of β-sesquiphellandrene by 1.25-1.60 fold. The highest amount achieved was 33 nM at 2 h post-induction.

    Full Text Available In this paper we analyse the impact of financial liberalization and reforms on the banking performance in 17 countries from CEE for the period 2004-2008 using a two-stage empirical model that involves estimating bank performance in the first stage and assessing its determinants in the second one. From our analysis it results that banks from CEE countries with higher level of liberalization and openness are able to increase cost efficiency and eventually to offer cheaper services to clients. Banks from non-member EU countries are less cost efficient but experienced much higher total productivity growth level, and large sized banks are much more cost efficient than medium and small banks, while small sized banks show the highest growth in terms of productivity.

  5. Danish wind power export and cost

    2010-02-15

    In a normal wind year, Danish wind turbines generate the equivalent of approx. 20 percent of the Danish electricity demand. This paper argues that only approx. 1 percent of the wind power production is exported. The rest is used to meet domestic Danish electricity demands. The cost of wind power is paid solely by the electricity consumers and the net influence on consumer prices was as low as 1-3 percent on average in the period 2004-2008. In 2008, the net influence even decreased the average consumer price, although only slightly. In Denmark, 20 percent wind power is integrated by using both local resources and international market mechanisms. This is done in a way which makes it possible for our neighbouring countries to follow a similar path. Moreover, Denmark has a strategy to raise this share to 50 percent and the necessary measures are in the process of being implemented. Recently, a study made by the Danish think tank CEPOS claimed the opposite, i.e. that most of the Danish wind power has been exported in recent years. However, this claim is based on an incorrect interpretation of statistics and a lack of understanding of how the international electricity markets operate. Consequently, the results of the CEPOS study are in general not correct. Moreover, the CEPOS study claims that using wind turbines in Denmark is a very expensive way of reducing CO{sub 2} emissions and that this is the reason for the high energy taxes for private consumers in Denmark. These claims are also misleading. The cost of CO{sub 2} reduction by use of wind power in the period 2004-2008 was only 20 EUR/ton. Furthermore, the Danish wind turbines are not paid for by energy taxes. Danish wind turbines are given a subsidy via the electricity price which is paid by the electricity consumers. In the recent years of 2004-2008, such subsidy has increased consumer prices by 0.54 EURO/kWh on average. On the other hand, however, the same electricity consumers also benefitted from the wind

    Prior to the launch of the EU Emissions Trading System (EU ETS) in 2005, the electricity sector was widely proclaimed to have more low-cost emission abatement opportunities than other sectors. If this were true, effects of the EU ETS on carbon dioxide (CO{sub 2}) emissions would likely be visible in the electricity sector. Our study looks at the effect of the price of emission allowances (EUA) on CO{sub 2} emissions from Swedish electricity generation, using an econometric time series analysis for the period 2004-2008. We control for effects of other input prices and hydropower reservoir levels. Our results do not indicate any link between the price of EUA and the CO{sub 2} emissions of Swedish electricity production. A number of reasons may explain this result and we conclude that other determinants of fossil fuel use in Swedish electricity generation probably diminished the effects of the EU ETS

    In this paper we focus on the application of transferable, object-based image analysis algorithms for dwelling extraction in a camp for internally displaced people (IDP) in Darfur, Sudan along with innovative means for scientific visualisation of the results. Three very high spatial resolution satellite images (QuickBird: 2002, 2004, 2008) were used for: (1) extracting different types of dwellings and (2) calculating and visualizing added-value products such as dwelling density and camp structure. The results were visualized on virtual globes (Google Earth and ArcGIS Explorer) revealing the analysis results (analytical 3D views,) transformed into the third dimension (z-value). Data formats depend on virtual globe software including KML/KMZ (keyhole mark-up language) and ESRI 3D shapefiles streamed as ArcGIS Server-based globe service. In addition, means for improving overall performance of automated dwelling structures using grid computing techniques are discussed using examples from a similar study.

    Full Text Available The paper analyses the impact of the economic crisis on the insurance industries of the ex-Yugoslavia region. The analysis encompasses five countries: Slovenia, Croatia, Serbia, Bosnia and Herzegovina, and FYR Macedonia. We examine insurance industry specifics separately for each country for the period 2004-2008 and for the first six months of 2009. While the impact of the crisis varies between countries, the research results indicate that the global financial crisis has had limited overall impact on the regional insurance industry. However the current recession resulted in negative premium growth in Serbia, Croatia and FYR Macedonia while the growth in Slovenia and Bosnia and Herzegovina declined. At the same time investment returns have declined and claims have risen in all countries. The crisis had more pronounced impact on non-life insurance premium growth in less developed insurance markets. In developed markets, namely Slovenia and Croatia, the crisis had greater impact on life insurance premium growth.

    2016-12-01

    Full Text Available The Sub-Saharan Africa belongs to the most underdeveloped regions in the world economy. This region consists of forty nine countries but it’s world GDP share is only a small percentage. There are some very resource rich countries in this region. One of them is Angola. This former Portuguese colony has one of the largest inventories of oil among all African countries. Angola recorded one of the highest growth of GDP between 2004-2008 from all countries in the world economy and nowadays is the third biggest economy in Sub-Saharan Africa after Nigeria and South Africa. The essential problem of Angola is the one-way oriented economy on oil and general on natural resources. Angola will be forced to change their one-way oriented economy to be more diversified and competitive in the future.

  1. Meta-analyzing dependent correlations: an SPSS macro and an R script.

    Science.gov (United States)

    Cheung, Shu Fai; Chan, Darius K-S

    2014-06-01

    The presence of dependent correlation is a common problem in meta-analysis. Cheung and Chan (2004, 2008) have shown that samplewise-adjusted procedures perform better than the more commonly adopted simple within-sample mean procedures. However, samplewise-adjusted procedures have rarely been applied in meta-analytic reviews, probably due to the lack of suitable ready-to-use programs. In this article, we compare the samplewise-adjusted procedures with existing procedures to handle dependent effect sizes, and present the samplewise-adjusted procedures in a way that will make them more accessible to researchers conducting meta-analysis. We also introduce two tools, an SPSS macro and an R script, that researchers can apply to their meta-analyses; these tools are compatible with existing meta-analysis software packages.

    This paper analyzes ownership and unobserved managerial ability as factors affecting the performance of a representative sample of Portuguese wind farms by means of frontier models. These farms are ranked according to their technical efficiency during the period 2004-2008 and homogenous and heterogeneous variables are disentangled in the cost function, which leads us to advise the implementation of common policies as well as policies by segments. Economic implications arising from the study are also considered. - Research highlights: → Wind farms are heterogeneous displaying distinct ownership and managerial characteristics that affect efficiency. → Managerial practices has a positive impact on the efficiency. → Ownership has a positive impact on the efficiency. Large wind farms are more efficient.

    Full Text Available South latitude and household economic control by Peruvian women Southern women’s greater autonomy versus northern women’s more traditional submission to the husband were hypothesized in 1984 to explain variations in Peruvian women’s fertility desires. An analysis of data from Peru 2004-2008 Continuous Demographic and Family Health Survey supports this hypothesis by showing a significant north-to-south growth of women’s control upon husband’s income and, less consistently, household purchasing decisions. These relationships are not explained by variables also correlated with meridionality, such as aboriginal ethnicity, women’s material/informational power, age difference with the husband’s, or working for cash. Findings suggest new hypotheses, concerning the distribution of assertiveness and warmth in the Peruvian territory.

    Full Text Available The exercise of legal authority over subsidies by Public Authorities has beena permanent source of jurisdictional controversies on a constitutional scale.The persistence of conflicts relating to this is better understood at timeswhen a decrease in the number of general conflicts between the CentralGovernment and the Autonomous Communities occurs. To take an obviousexample, this is true for the VIII Legislature (2004-2008, in which the notablereduction in the total number of jurisdictional controversies formally broughtbefore the Constitutional Court is in stark contrast with the increased numberof conflicts relating to public subsidies. In recent years several pieces ofnew legislation have been passed, themselves not exempt from questions regardingtheir constitutionality, which may contribute to reducing the numberof these conflicts. For this objective to be achieved, it will be necessaryboth for the various involved regional governments to be loyal, and for theprocedural instruments that the Constitutional Court has at its disposal to bebetter used.

    The distribution of tritium in water vapour and precipitation with discharge of tritiated water vapour and meteorological factors was studied around the Wolsung nuclear power plant (NPP) site during the period 2004-2008. The tritium concentrations in atmospheric water vapour and precipitation had a temporal variation with relatively high values in the early summer. Spatial distribution of tritium concentrations was affected by various factors such as distance from the NPP site, wind direction, tritium discharge into the atmosphere and atmospheric dispersion factor. The annual mean concentrations of atmospheric HTO and precipitation were correlated with the amount of gaseous tritium released from the Wolsung NPP. The tritium concentrations in precipitation decrease exponentially with an increase of the distance from the Wolsung NPP site.

    Full Text Available Estonia and other Baltic countries experienced speculative boom in years 2004-2008. The boom resulted in rapidly rising relative price level or real exchange rate. Euro wages are used as proxies for bilateral real exchange rates. Rapid reversal of capital inflow created instantly short-term real exchange rate overvaluation. The data shows that some other developing countries, like Poland and Russia let their price level to adjust through depreciation of nominal exchange rate. Estonia and other Baltic countries decided to go through adjustment with deflation of prices and wages. This contributed to higher unemployment rate and GDP loss. The most positive way out appears to be restoration of foreign investors interest in local economy and raising equilibrium real exchange rate reducing likely real exchange rate overvaluation. The other important implication was that local businessmen and other individuals were too much risk-takers for volatile emerging market economy.

    Full Text Available The objective of this paper is to test empirical validity of Fear of Floating hypothesis for Turkey after the adoption of Inflation Targeting. We start applying methodologies developed by Calvo and Reinhart (2002 and Ball and Reyes (2004, 2008 to check the probabilities of changes in exchange rate and monetary policy instruments before and after inflation targeting regime. We then use a VAR model to estimate exchange rate pass-through and response of monetary policy instruments to exchange rate shocks before and after inflation targeting regime. VAR model helps to understand the impacts of switch in monetary policy regime on exchange rate pass-through and foreign exchange market interventions. The paper concludes that after the adoption of inflation targeting regime, the exchange rate pass-through still matters for the attainment of inflation targets and the monetary policy do not exhibit a fear of floating practices.

    2010-01-01

    In this paper, we use publicly available data from the Medical Expenditure Panel Survey - Insurance Component (MEPS-IC) to investigate the effect of Massachusetts' health reform plan on employer-sponsored insurance premiums. We tabulate premium growth for private-sector employers in Massachusetts and the United States as a whole for 2004 - 2008. We estimate the effect of the plan as the difference in premium growth between Massachusetts and the United States between 2006 and 2008-that is, before versus after the plan-over and above the difference in premium growth for 2004 to 2006. We find that health reform in Massachusetts increased single-coverage employer-sponsored insurance premiums by about 6 percent, or $262. Although our research design has important limitations, it does suggest that policy makers should be concerned about the consequences of health reform for the cost of private insurance.

    The analysis of drought impacts is essential to define efficient and sustainable management and mitigation. In this paper we present a detailed analysis of the impacts of the 2004-2008 drought in the agricultural sector in the Ebro river basin (Spain). An econometric model is applied in order to determine the magnitude of the economic loss attributable to water scarcity. Both the direct impacts of drought on agricultural productivity and the indirect impacts of drought on agricultural employment and agroindustry in the Ebro basin are evaluated. The econometric model measures losses in the economic value of irrigated and rainfed agricultural production, of agricultural employment and of Gross Value Added both from the agricultural sector and the agro-industrial sector. The explanatory variables include an index of water availability (reservoir storage levels for irrigated agriculture and accumulated rainfall for rainfed agriculture), a price index representative of the mix of crops grown in each region, and a time variable. The model allows for differentiating the impacts due to water scarcity from other sources of economic losses. Results show how the impacts diminish as we approach the macro-economic indicators from those directly dependent on water abstractions and precipitation. Sectors directly dependent on water are the most affected with identifiable economic losses resulting from the lack of water. From the management perspective implications of these findings are key to develop mitigation measures to reduce drought risk exposure. These results suggest that more open agricultural markets, and wider and more flexible procurement strategies of the agro-industry reduces the socio-economic exposure to drought cycles. This paper presents the results of research conducted under PREEMPT project (Policy relevant assessment of the socioeconomic effects of droughts and floods, ECHO - grant agreement # 070401/2010/579119/SUB/C4), which constitutes an effort to provide

    Two closed horse herds (Old Lot 4 and Field 24), infected since 1966 with Population B small strongyles resistant to thiabendazole (TBZ) and phenothiazine (PTZ), were terminated in February, March, and May, 2005. At necropsy, only the large endoparasites were identified and counted. The number of horses on pasture was 14 (239 days of age to 23 years old) for Old Lot 4 and two (3 to 20 years old) for Field 24. The time of the last antiparasitic treatment, relative to the year (2005) of necropsy, was 26 years for Old Lot 4 and 9 years for Field 24 horses. Gasterophilus intestinalis third instars (three to 113 specimens/horse) were found in all 16 horses and second instars (one to two) in two horses. Gasterophilus nasalis third instars (one to three) were recovered from five horses. Parascaris equorum infections (23 to 144) were in four horses (239 days to 4 years old). Strongylus vulgaris were present in the large intestine (one to 155) of 13 horses from 239 days to 23 years old and in the cranial mesenteric artery (two to 79) in 10 horses from 239 days to 23 years old. Strongylus edentatus were in the large intestine (two to 101) of 12 horses, ranging in age from 2.5 to 23 years old and in the ventral abdominal wall (one to 53) of six horses from 239 days to 21 years old. Specimens (seven to 872) of Anoplocephala perfoliata were in all horses. Oxyuris equi (one to 129) were recovered from seven horses (330 days to 23 years old). Thelazia lacrymalis (one to 85) infected the eyes of five horses (317 days to 11 years old).

    Abeer M. El Sayed

    Full Text Available Abstract Genus Aloe, Xanthorrhoeaceae, is well distributed all over Egypt, and many species have been used as medicinal plants; mainly reported to prevent cardiovascular diseases, cancer and diabetes. This study attempts to analyze the secondary metabolites in the methanol extract of the leaves of eight Aloe species; A. vera (L. Burm. f., A. arborescens Mill., A. eru A. Berger, A. grandidentata Salm-Dyck, A. perfoliata L., A. brevifolia Mill., A. saponaria Haw. and A. ferox Mill. growing in Egypt. For this aim HPLC–DAD–MS/MS in negative ion mode was used. Although belonging to the same genus, the composition of each species presented different particularities. Seventy one compounds were identified in the investigated Aloe species, of which cis-p-coumaric acid derivaties, 3,4-O-(E caffeoylferuloylquinic acid and caffeoyl quinic acid hexoside were the most common phenolic acids identified. Aloeresin E and isoaloeresin D, 2'-O-feruloylaloesin were the common anthraquinones identified. Lucenin II, vicenin II, and orientin were the common identified flavonoids in the investigated Aloe species. 6'-Malonylnataloin, aloe-emodin-8-O-glucoside, flavone-6,8-di-C-glucosides could be considered as chemotaxonomic markers for the investigated Aloe species. The eight Aloe species had significant anti-inflammatory activity, in addition to the significant acceleration of diabetic wound healing in rats following topical application of the methanol extracts of their leaves. This is the first simultaneous characterization and qualitative determination of multiple phenolic compounds in Aloe species from locally grown cultivars in Egypt using HPLC–DAD–MS/MS, which can be applied to standardize the quality of different Aloe species and the future design of nutraceuticals and cosmetic preparations.

It is a detailed study of this group of plants, conducted for the first time in the Ukraine. The checklist of alien vascular plants contains 345 species, of which 27 species are ephemerophytes (or 8%: Adonis aestivalis, A. annua, Papaver albiflorum, Urtica cannabina, Gypsophila perfoliata, Atriplex micrantha, Chenopodium × preissmannii, Ch. × thellungii, Rumex longifolius, Sisymbrium polymorphum, Euphorbia humifusa, Malus sylvestris, Onobrychis viciifolia, Astrodaucus orientalis, Datura tatula, Solanum schultesii, Lindernia procumbens, Melampyrum cristatum, Helianthus annuus, Petasites spurius, Xanthium ripicola × Xanthium albinum, Echinochloa tzvelevii, Panicum capillare, Panicum capillare L. subsp. barvipulvinatum, Phalaris canariensis, Setaria ×ambigua, Sorghum halepense. The basis of this work is original data of the author obtained during field studies, and a critical study of the literature, archival, cartographic materials and herbarium collections, and the use of classical methods of botanical classification. Complex research of this group of plants was conducted and as a result of these investigations the following characteristics were established: a predominance of kenophytes of Mediterranean origin in this group, species of arid areas, cosmopolitan species with a diffuse type of space structure, therophytes, herbaceous monocarpic plants, mesotrophes, heliophytes and xeromesophytes, with an insignificant degree of impact on native plant communities and with a limited distribution within the study region. The combination of these results indicates that ephemerophytes comprise a temporary, unstable component of the flora of this region of the Ukraine. The paper provides maps of the distribution of these 27 species.

  19. Comparative Genomics of Smut Pathogens: Insights From Orphans and Positively Selected Genes Into Host Specialization

    Directory of Open Access Journals (Sweden)

    Juliana Benevenuto

    2018-04-01

    Full Text Available Host specialization is a key evolutionary process for the diversification and emergence of new pathogens. However, the molecular determinants of host range are poorly understood. Smut fungi are biotrophic pathogens that have distinct and narrow host ranges based on largely unknown genetic determinants. Hence, we aimed to expand comparative genomics analyses of smut fungi by including more species infecting different hosts and to define orphans and positively selected genes to gain further insights into the genetics basis of host specialization. We analyzed nine lineages of smut fungi isolated from eight crop and non-crop hosts: maize, barley, sugarcane, wheat, oats, Zizania latifolia (Manchurian rice, Echinochloa colona (a wild grass, and Persicaria sp. (a wild dicot plant. We assembled two new genomes: Ustilago hordei (strain Uhor01 isolated from oats and U. tritici (strain CBS 119.19 isolated from wheat. The smut genomes were of small sizes, ranging from 18.38 to 24.63 Mb. U. hordei species experienced genome expansions due to the proliferation of transposable elements and the amount of these elements varied among the two strains. Phylogenetic analysis confirmed that Ustilago is not a monophyletic genus and, furthermore, detected misclassification of the U. tritici specimen. The comparison between smut pathogens of crop and non-crop hosts did not reveal distinct signatures, suggesting that host domestication did not play a dominant role in shaping the evolution of smuts. We found that host specialization in smut fungi likely has a complex genetic basis: different functional categories were enriched in orphans and lineage-specific selected genes. The diversification and gain/loss of effector genes are probably the most important determinants of host specificity.

  20. Susceptibility of riparian wetland plants to perfluorooctanoic acid (PFOA) accumulation.

    As plants have been shown to accumulate organic compounds from contaminated sediments, there is a potential for long-lasting ecological impact as a result of contaminant accumulation in riparian areas of wetlands, particularly the accumulation of non-biodegradable contaminants such as perfluorooctanoic acid (PFOA). In this study, commonly found riparian wetland plants including reeds, i.e., Xanthium strumarium, Phragmites australis, Schoenoplectus corymbosus, Ruppia maritime; Populus canescens, Polygonum salicifolium, Cyperus congestus; Persicaria amphibian, Ficus carica, Artemisia schmidtiana, Eichhornia crassipes, were studied to determine their susceptibility to PFOA accumulation from PFOA contaminated riparian sediment with a known PFOA concentration, using liquid chromatography/tandem mass spectrometry (LC/MS/MS). The bioconcentration factor (BCF) indicated that the plants affinity to PFOA accumulation was; E. crassipes, > P. sali-cifolium, > C. congestus, > P. x canescens, > P. amphibian, > F. carica, > A. schmidtiana, > X. strumarium,> P. australis, > R. maritime, > S. corymbosus. The concentration of PFOA in the plants and/or reeds was in the range 11.7 to 38 ng/g, with a BCF range of 0.05 to 0.37. The highest BCF was observed in sediment for which its core water had a high salinity, total organic carbon and a pH which was near neutral. As the studied plants had a higher affinity for PFOA, the resultant effect is that riparian plants such as E. crassipes, X. strumarium, and P. salicifolium, typified by a fibrous rooting system, which grow closer to the water edge, exacerbate the accumulation of PFOA in riparian wetlands.

  1. Carbon isotopes of C3 herbs correlate with temperature on removing the influence of precipitation across a temperature transect in the agro-pastoral ecotone of northern China.

    Plant δ 13 C-temperature (δ-T) relation has been established in many systems and is often used as paleotemperature transfer function. However, it is still unclear about the exact contributions of temperature variation to plant 13 C discrimination because of covariation between temperature and precipitation (aridity), which reduces confidence in reconstruction of paleoclimate. In this study, we measured carbon isotope composition (δ 13 C) of 173 samples of C3 perennial herbs from 22 sites across a temperature gradient along the 400 mm isohyet in the farming-pastoral zone of North China. The results showed that precipitation obviously affected the correlations of temperatures and foliar δ 13 C. After removing the influence of precipitation by analysis of covariance (ANCOVA), a more strongly positive relationship was obtained between site-mean foliar δ 13 C and annual mean temperature (AMT), with a regression coefficient of 0.1636‰/°C ( p  =   .0024). For widespread species, Artemisia lavandulaefolia and Artemisia capillaries , the slopes (or coefficients) of foliar δ 13 C and AMT were significantly steeper (larger) than those of foliar δ 13 C and AMT where the precipitation influence was not excluded, whereas the δ-T coefficients of Polygonum persicaria and Leymus chinensis showed little change across the transect after deducting the precipitation effect. Moreover, the positive relationship between temperature and δ 13 C over the transect could be explained by soil moisture availability related to temperature. Our results may afford new opportunities for investigating the nature of past climate variability.

  2. Anti-caries activity of selected Sudanese medicinal plants with emphasis on Terminalia laxiflora

    Ebtihal Abdalla M. Mohieldin

    Full Text Available Abstract In Sudan, some medicinal plants, such as Acacia seyal, Calotropis procera and Balanites aegyptiaca have been used to prevent or treat oral health problems. The stem and stem bark of Terminalia laxiflora Engl., Combretaceae, are used as antiseptics for mouthwash to prevent gingivitis and thrush in Africa. Methanol and 50% hydroethanolic extracts of 25 plants that are used in traditional Sudanese medicine for several diseases and cavity disorders were screened for anti-cavity activities. T. laxiflora methanolic wood extracts, which exhibited such activity, were investigated. The crude extracts were assayed for their antimicrobial activities against Streptococcus sobrinus in terms of minimum inhibitory concentration and glucosyltransferase inhibition. The active extract of T. laxiflora wood was subsequently fractionated by different chromatographic techniques. Isolated compounds were identified by spectroscopic methods and assessed for S. sobrinus and glucosyltransferase inhibitory effects. Methanolic extracts of Terminalia brownii (bark, T. laxiflora (wood, A. seyal (bark, Persicaria glabra (leaves and Tamarix nilotica (stem showed good activities against both S. sobrinus and glucosyltransferase (MIC ≤ 1 mg/ml, IC50 values <50 µg/ml. Over all plant extracts, T. laxiflora demonstrated the good combined activities (MIC 0.5 mg/ml, glucosyltransferase, IC50 10.3 µg/ml; therefore, its methanolic wood extracts were selected for further phytochemical studies. Four constituents were isolated by chromatographic techniques and identified by spectroscopic techniques. Pharmacological evaluation of the obtained compounds showed that flavogallonic acid dilactone had comparatively good antibacterial activity. In the glucosyltransferase inhibitory test, terchebulin displayed potent activity with an IC50 of 7.5 µM. The screening presented in this study showed that methanol extracts of T. laxiflora wood possessed promising anti-cavity effects.

    Full Text Available Segetal flora of cereal crop agrocenoses in the Suwałki Landscape Park was studied in between the years 2012 and 2013. One hundred phytosociological Braun-Blanquet releves were taken, documenting the occurrence of 152 species of vascular plants that represented 29 botanic families. Analysis of the contributions of geographic-historical groups revealed the dominance of the native species, apophytes (87 species, making 57.2%, over anthropophytes (65 species, 42.8%. The number of short-lived species was twice greater (103 species, 67.8% than the perennial ones (49 species, 32.2%. As regards the lifeforms, the therophytes were dominant (96 species, 63.2% over hemicryptophytes (44 species, 28.9% and geophytes (12 species, 7.9%. Among the species of segetal flora in the area studied, 23 valuable species classified to different categories of protection, were identified. The presence of Consolida regalis, Centaurea cyanus and Bromus secalinus, belonging to threatened species in other regions of Poland, was abundant. Also the species: Anthemis tinctoria, Echium vulgare and Anchusa officinalis were met with high frequency. The species: Agrostemma githago, Papaver argemone and Papaver dubium were represented by single plants, which can suggest their dying out. In the Park area, expansive species, threatening the biodiversity, such as Myosotis arvensis, Viola arvensis, Galeopsis tetraehit, Stellaria media, Artemisia vulgaris, Galinsoga parviflora, Elymus repens, Capsella bursa pastoris, Erodium cicutarium, Chamomilla recutita, Matricaria maritima subsp. inodora, Convolvulus arvensis, Polygonum persicaria, Polygonum lapathifolium subsp. pallidum and Polygonum lapathifolium subsp. lapathifolium, were commonly seen in the crop land.

    Full Text Available Weed communities of organically cropped spring cereal stands in the southern and the northwestern coastal regions of Finland (= south and northwest, respectively were compared with respect to number of species, frequency of occurrence, density and dry weight. Regional specialization of agricultural production along with differences in climate and soil properties were expected to generate differences in weed communities between south and northwest. Total and average numbers of species were higher in the south than in the northwest (33 vs. 26 and 15.6 vs. 10.0, respectively. Some rare species (e.g. Papaver dubium were found in the south. Fumaria officinalis and Lamium spp. were found only in the south. The densities and dry weights of Lapsana communis, Myosotis arvensis, Polygonum aviculare, Tripleurospermum inodorum and Vicia spp. were higher in the south, while the densities and dry weights of Elymus repens, Persicaria spp. and Spergula arvensis were higher in the northwest. Total density of weeds did not differ between south and northwest (average = 565 vs. 570 shoots m-2, respectively. Total dry weight of weeds was higher in the northwest compared with the south (average = 1594 vs. 697 kg ha-1, respectively, mainly due to the high dry weight of E. repens. The only variable that was dependent on the duration of organic farming was weed density in the south. The abundance of nitrophilous in relation to non-nitrophilous weed species was higher while the abundance of perennial ruderal and grassland weed species was lower compared with previous weed surveys. This can be regarded as the result of increasing cropping intensity on organic farms in Finland. Different weed communities call for the application of specific target-oriented weed management in the respective coastal regions.;

    Full Text Available Field studies were carried out in 1989–1995 and 2006–2012 on plantations of sugar beet (Beta vulgaris L. subsp. vulgaris. During this period, 542 phytosociological relevés were made using the Braun-Blanquet method. In total, 46 weed species were found. In 1989–1995, the occurrence of 36 segetal species was reported. The highest cover indices were determined for Chenopodium album and Amaranthus retroflexus. Galium aparine, Echinochloa crus-galli, and Elymus repens were the dominant species, as well. Analysis of the frequency of occurrence revealed one constant species (Chenopodium album, two frequent species (Amaranthus retroflexus and Galium aparine, and two medium-frequent species (Echinochloa crus-galli and Matricaria maritima ssp. inodora. In 2006–2012, the occurrence of 40 weed species on the sugar beet plantations was recorded. The plantations were clearly dominated by Chenopodium album, accompanied by Polygonum persicaria and Polygonum lapathifolium ssp. lapathifolium. Other dominant species comprised Setaria viridis, Galinsoga parviflora, Brassica napus ssp. napus, and Fallopia convolvulus. The Chenopodium album was a constant component of the sugar beet plantations. In turn, no frequent species were observed and six medium-frequent species were found (Setaria viridis, Galinsoga parviflora, Brassica napus ssp. napus, Echinochloa crus-galli, Amaranthus retroflexus, and Capsella bursa-pastoris. Noteworthy, the presence of previously unreported species, e.g., Abutilon theophrasti, Hyoscyamus niger, or Artemisia vulgaris, was revealed. These species are rare components in sugar beet crops. A reverse phenomenon, i.e., the disappearance of some species such as Euphorbia helioscopia, Malva neglecta, Rumex acetosella, Sinapis arvensis, or Sisymbrium officinale, was also observed.

    Full Text Available Increasing maize cultivation and changed cropping practices promote the selection of typical maize weeds that may also profit strongly from climate change. Predicting potential weed problems is of high interest for plant production. Within the project KLIFF, experiments were combined with species distribution modelling for this task in the region of Lower Saxony, Germany. For our study, we modelled ecological and damage niches of nine weed species that are significant and wide spread in maize cropping in a number of European countries. Species distribution models describe the ecological niche of a species, these are the environmental conditions under which a species can maintain a vital population. It is also possible to estimate a damage niche, i.e. the conditions under which a species causes damage in agricultural crops. For this, we combined occurrence data of European national data bases with high resolution climate, soil and land use data. Models were also projected to simulated climate conditions for the time horizon 2070 - 2100 in order to estimate climate change effects. Modelling results indicate favourable conditions for typical maize weed occurrence virtually all over the study region, but only a few species are important in maize cropping. This is in good accordance with the findings of an earlier maize weed monitoring. Reaction to changing climate conditions is species-specific, for some species neutral (E. crus-galli, other species may gain (Polygonum persicaria or loose (Viola arvensis large areas of suitable habitats. All species with damage potential under present conditions will remain important in maize cropping, some more species will gain regional importance (Calystegia sepium, Setara viridis.

    Preliminary phytochemical and flavonoid compounds of aqueous and ethanolic extracts of 6 aromatic Malaysian herbs were screened and quantified using Reverse-Phase High Performance Liquid Chromatography (RP-HPLC). The herbal extracts were tested for their antimicrobial activity against 10 food-borne pathogenic and food spoilage microorganisms using disk diffusion assay. The minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC)/minimum fungicidal concentration (MFC) of herbal extracts were determined. In the phytochemical screening process, both aqueous and ethanolic extracts of P. hydropiper exhibited presence of all 7 tested phytochemical compounds. Among all herbal extracts, the aqueous P. hydropiper and E. elatior extracts demonstrated the highest antibacterial activity against 7 tested Gram-positive and Gram-negative bacteria with diameter ranging from 7.0 to 18.5 mm and 6.5 to 19 mm, respectively. The MIC values for aqueous and ethanolic extracts ranged from 18.75 to 175 mg/mL and 0.391 to 200 mg/mL, respectively while the MBC/MFC values for aqueous and ethanolic extracts ranged from 25 to 200 mg/mL and 3.125 to 50 mg/mL, respectively. Major types of bioactive compounds in aqueous P. hydropiper and E. elatior extracts were identified using RP-HPLC instrument. Flavonoids found in these plants were epi-catechin, quercetin, and kaempferol. The ability of aqueous Persicaria hydropiper (L.) H. Gross and Etlingera elatior (Jack) R.M. Sm. extracts to inhibit the growth of bacteria is an indication of its broad spectrum antimicrobial potential. Hence these herbal extracts may be used as natural preservative to improve the safety and shelf-life of food and pharmaceutical products. © 2014 Institute of Food Technologists®

    Acute myocardial infarction is one of the leading causes of death in the world. This is also true in Cuba, where no national-level epidemiologic studies of related mortality have been published in recent years. Describe acute myocardial infarction mortality in Cuba from 1999 through 2008. A descriptive study was conducted of persons aged ≥25 years with a diagnosis of acute myocardial infarction from 1999 through 2008. Data were obtained from the Ministry of Public Health's National Statistics Division database for variables: age; sex; site (out of hospital, in hospital or in hospital emergency room) and location (jurisdiction) of death. Proportions, age- and sex-specific rates and age-standardized overall rates per 100,000 population were calculated and compared over time, using the two five-year time frames within the study period. A total of 145,808 persons who had suffered acute myocardial infarction were recorded, 75,512 of whom died, for a case-fatality rate of 51.8% (55.1% in 1999-2003 and 49.7% in 2004-2008). In the first five-year period, mortality was 98.9 per 100,000 population, falling to 81.8 per 100,000 in the second; most affected were people aged ≥75 years and men. Of Cuba's 14 provinces and special municipality, Havana, Havana City and Camagüey provinces, and the Isle of Youth Special Municipality showed the highest mortality; Holguín, Ciego de Ávila and Granma provinces the lowest. Out-of-hospital deaths accounted for the greatest proportion of deaths in both five-year periods (54.8% and 59.2% in 1999-2003 and 2004-2008, respectively). Although risk of death from acute myocardial infarction decreased through the study period, it remains a major health problem in Cuba. A national acute myocardial infarction case registry is needed. Also required is further research to help elucidate possible causes of Cuba's high acute myocardial infarction mortality: cardiovascular risk studies, studies of out-of-hospital mortality and quality of care

    Full Text Available El análisis jerárquico de intensidad de cambio de cobertura/uso de suelo es un  marco cuantitativo de análisis espacial anidado que permite estimar los cambios en tres niveles de orden,  intervalo de tiempo, categoría y transición, a partir de una matriz de cambio. Presentamos su aplicación  para dos periodos de tiempo 2000-2004 y 2004-2008 en la Reserva de la Biosfera Sierra de Manantlán, área de estudio altamente heterogénea en términos de los tipos de vegetación y usos del suelo. Se usó cartografía del INEGI a escala 1:50 000 actualizada mediante una imagen Landsat ETM+ del 2000 e imágenes SPOT para 2004 y 2008. El análisis permitió conocer en qué intervalo de tiempo la tasa anual general de cambio es más rápida, cuáles son las categorías más activas y cuáles son latentes; cuáles son las categorías objetivo para las transiciones activas, y si el patrón de cambio es estable en el tiempo. Se observó una mayor tasa anual de cambio entre 2000 y 2004 en comparación con el periodo 2004-2008. A nivel de categorías, se encontraron altas tasas de deforestación de las selvas tropicales hacia usos agropecuarios, y latencia en bosques templados con baja intensidad de transición hacia usos agropecuarios. En particular la actividad ganadera arraigada en la región aparece como factor promotor del proceso de deforestación, que en la praxis sobre el terreno se expresa diferencialmente en selvas y bosques.

La gestión se estudió desde los objetivos y estrategias; prácticas directivas; estructura y organización; métodos, instrumentos y herramientas, y cultura y personalidad. Se trabajó bajo un enfoque cualitativo, la recolección de la información se hizo a través de observación, realización de entrevistas y revisión documental utilizando como herramienta de análisis la hermenéutica. Se seleccionaron cuatro unidades de análisis, atendiendo al criterio de liderazgo en investigación en el ámbito nacional, éstas son: Universidad de los Andes (ULA, Universidad Central de Venezuela (UCV, Universidad Simón Bolívar (USB y Universidad del Zulia (LUZ. Por otro lado, el período 2004-2008 obedece a que es la última gestión rectoral finalizada y por tanto susceptible de ser analizada. Los resultados revelan que 1 De las universidades estudiadas, ULA; UCV y LUZ manejan modelos de gestión burocráticos y centralizados, con ciertas particularidades, mientras que, el de la USB es flexible y menos centralizado. 2 Aun cuando la USB exhibe mayor fortaleza general en investigación, se evidenciaron prácticas puntuales en ULA, LUZ y UCV que convendría replicar en el resto de las universidades. Se concluye, en primer lugar, que para las universidades tradicionales, es un imperativo cambiar el modelo de gestión dominante que frena el desarrollo de la investigación; en segundo lugar, si las universidades hacen sinergia entre las mejores prácticas de cada una, podrían catapultar la investigación universitaria venezolana y colocarla en el mapa mundial, haciéndola más independiente del gobierno de turno desde el punto de vista financiero.

    The Food and Drug Administration approved pre-exposure prophylaxis (PrEP) to prevent HIV infection, and the Centers for Disease Control and Prevention has presented PrEP as a prevention option for groups at high risk such as men who have sex with men (MSM). Intervention data provide some information on how PrEP affects sexual behavior of MSM in trials, open label extensions, or clinics. However, it is unclear whether sexual risk and preventive behavioral patterns are changing in the population as a whole as PrEP becomes more widely available, whether due to PrEP use or other factors. We examined trends in PrEP use, numbers of condomless anal sex partners, consistent condom use, and seroadaptive strategies in San Francisco-a city which has actively promoted PrEP-using data from National HIV Behavioral Surveillance (NHBS). NHBS recruited 1211, 383, 373, and 268 HIV-negative MSM in 2004, 2008, 2011, and 2014, respectively. PrEP use increased from zero in 2004, 2008, and 2011 to 9.6 % in 2014. The proportion of men with no condomless anal sex partners dropped from 60.6 % in 2004, to 58.2 % in 2008, to 54.2 % in 2011, to 40.2 % in 2014. Consistent condom use decreased from 36.8 % in 2004, and 30.5 % in 2008 and 2011, to 18.3 % in 2014. PrEP's introduction and scale-up enters in a pre-existing trend of decreasing condom use and increasing sexually transmitted infections among MSM which may be accelerating in recent years. While PrEP use should be scaled up as a prevention option among those who would benefit most, we believe that public health officials need to be realistic about the possibility that condom use could very well continue to decline as PrEP use increases, and to an extent that may not be directly or indirectly offset by PrEP.

    Area-based socioeconomic measures are widely used in health research. In theory, the larger the area used the more individual misclassification is introduced, thus biasing the association between such area level measures and health outcomes. In this study, we examined the socioeconomic disparities in cancer survival using two geographic area-based measures to see if the size of the area matters. We used population-based cancer registry data for patients diagnosed with one of 10 major cancers in New South Wales (NSW), Australia during 2004-2008. Patients were assigned index measures of socioeconomic status (SES) based on two area-level units, census Collection District (CD) and Local Government Area (LGA) of their address at diagnosis. Five-year relative survival was estimated using the period approach for patients alive during 2004-2008, for each socioeconomic quintile at each area-level for each cancer. Poisson-regression modelling was used to adjust for socioeconomic quintile, sex, age-group at diagnosis and disease stage at diagnosis. The relative excess risk of death (RER) by socioeconomic quintile derived from this modelling was compared between area-units. We found extensive disagreement in SES classification between CD and LGA levels across all socioeconomic quintiles, particularly for more disadvantaged groups. In general, more disadvantaged patients had significantly lower survival than the least disadvantaged group for both CD and LGA classifications. The socioeconomic survival disparities detected by CD classification were larger than those detected by LGA. Adjusted RER estimates by SES were similar for most cancers when measured at both area levels. We found that classifying patient SES by the widely used Australian geographic unit LGA results in underestimation of survival disparities for several cancers compared to when SES is classified at the geographically smaller CD level. Despite this, our RER of death estimates derived from these survival

    2012-12-01

    The explosivity of silicic eruptions depends on the interplay between magma rheology, exsolution kinetics, and degassing. Magma degassing is governed by the competing effects of vertical transport within the conduit and the lateral flux of gas out of the conduit (Diller et al., 2006; Jaupart and Allegre, 1991). We combine a simplified treatment of these degassing processes with thermodynamic modeling to examine the conditions present at Mount St. Helens during the spine extruding eruption from 2004 to 2008. We find that two parameters are primarily responsible for controlling the eruptive style: the magma chamber temperature, and a dimensionless parameter that gauges the efficiency of lateral degassing. Together, these parameters determine whether and where magma can solidify at depth to form a dense solid plug that is gradually extruded as a volcanic spine. We show that the small (50 oC) decrease in magma chamber temperature between eruptive activity in the 1980s and that of 2004-2008, combined with a modest increase in degassing efficiency associated with lower volumetric flux, can explain the observed change in erupted material from viscous lava flows to solidified spines. More generally, we suggest that similar threshold behavior may explain observed abrupt transitions in effusive eruptive styles at other intermediate composition volcanoes. Finally, we extrapolate our results to suggest that the increase in degassing efficiency accompanying decreasing magma supply rates may have caused the transition from explosive to effusive activity in late 1980.

    Motorcycles are the most popular means of transportation in northern Ghana, and their accidents are major causes of out-patient attendance and admissions in the Bolgatanga Municipality. This paper estimates the economic burden of motorcycle accidents in the Bolgatanga Municipality in Northern Ghana. Retrospective cross-sectional cost study. Data were collected from Drivers and Vehicle Licensing Authority, the Police, health facilities and motorcycle accident victims. Both quantitative and qualitative approaches were used for data collection. Cost analysis was based on the standard road accident cost conceptual framework. Ninety-eight percent of vehicles registered in the municipality in 2004 - 2008 were motorcycles. The motorcycles were significantly more than the cars registered. The economic burden of motorcycle accidents was estimated to be about US$1.2 million, of which, 52% were accident-related costs (i.e. property damage and administration) and 48% casualty-related costs (i.e. medical costs, out-of-pocket expenses, lost labour outputs, intangible costs and funeral expenses). Most motorcycle accident victims were in their productive ages and were males. Only a third of the motorcycles were insured. Majority of the riders (71%) did not possess valid driving license and would want to avoid the police. Main motorcycle injuries were head injuries, fractures, lacerations and contusions. Majority of the accidents were caused by lack of formal motorcycle riding training, abuse of alcohol, unrestrained animals and donkey carts. Motorcycle accidents could be reduced through law enforcement, continuous mass education and helmet use.

    Full Text Available The aim of this study was to investigate inequalities in survival for non-Hodgkin's lymphoma (NHL, distinguishing between direct and indirect effects of patient, social and process-of-care factors.All cases of NHL diagnosed in Ireland in 2004-2008 were included. Variables describing patient, cancer, stage and process of care were included in a discrete-time model of survival using Structural Equation Modelling software.Emergency admissions were more common in patients with co-morbid conditions or with more aggressive cancers, and less frequent for patients from more affluent areas. Aggressive morphology, female sex, emergency admission, increasing age, comorbidity, treatment in a high caseload hospital and late stage were associated with increased hazard of mortality. Private patients had a reduced hazard of mortality, mediated by systemic therapy, admission to high caseload hospitals and fewer emergency admissions.The higher rate of emergency presentation, and consequent poorer survival, of uninsured patients, suggests they face barriers to early presentation. Social, educational and cultural factors may also discourage disadvantaged patients from consulting with early symptoms of NHL. Non-insured patients, who present later and have more emergency admissions would benefit from better access to diagnostic services. Older patients remain disadvantaged by sub-optimal treatment, treatment in non-specialist centres and emergency admission.

We retrospectively identified 1,721 adults with blunt splenic injury (American Association for the Surgery of Trauma splenic injury scale grades III-V) from the 2004-2014 Japan Trauma Data Bank. We grouped the records of these patients into 3 time phases: phase I (2004-2008), phase II (2009-2012), and phase III (2013-2014). Over the 3 phases, we analysed 30-day mortality rates and investigated their association with the prevalence of certain initial interventions (Mantel-Haenszel trend test). We further performed multiple imputation and multivariable analyses for comparing the characteristics and outcomes of patients who underwent TAE or splenectomy/splenorrhaphy, adjusting for known potential confounders and for within-hospital clustering using generalised estimating equation. Over time, there was a significant decrease in 30-day mortality after splenic injury (p splenic injury between 2004 and 2014, even after adjustment for within-hospital clustering and other factors independently associated with mortality. Over time, mortality rates decreased significantly after splenectomy/splenorrhaphy, but not after non-operative management. This information is useful for clinicians when making decisions about treatments for patients with blunt splenic injury.

    Full Text Available Objective: Assessment of preoperative and postoperative outcomes of patients that were performed hysterescopic intrauterine adhesiolysis. Material and method: We reviewed 24 patients that underwent hysterescopy with the complaints of amenorrhea, hypomenorrhea, recurrent pregnancy loss between 2004-2008. The most complaints of patients were infertilty amenorrhea. Results: Adhesions occurs mainly as a result of trauma to the gravid uterine cavity in 14 patients. When classifying patients with their intrauterine adhesions, Grade 3 was the most frequently seen. Adhesiolisis was performed with hysteresopic scissors in all patients. In postoperative period following synechiolysis, 10 patients were treated with estrogen and progestogen, 11 of them used intrauterine device with estrogen and progestogen therapy, foley catheter was used in 3 patients. Hysterescopy was performed in 5 patients for second time because of adhesion suspicions. The re-adhesiolysis performed to 3 patients because of determined to mild adhesion. Conclusion: After hysterescopic adhesiolysis, all patients with the complaint of amenorrhea had regular menstruation. Pregnancy after treatment occured in 4 patients but live birth rate was 75%.

    Dynamic change in soil erosion is an important focus of regional ecological restoration research. Here, the dynamic changes of soil erosion and its driving forces in the Dahei Mountain ecological restoration area of northern China were analyzed by LANDSAT TM remote sensing captured via geographic information system (GIS) technologies during three typical periods in 2004, 2008 and 2013. The results showed the following: (1) a decrease in intensive erosion and moderate erosion areas, as well as an increase in light erosion areas, was observed during two periods: one from 2004 to 2008 and the other from 2008 to 2013. (2) Between 2004 and 2008, the variation in the range of slight erosion was the largest (24.28%), followed by light erosion and intensive erosion; between 2008 and 2013, the variation in the range of intensive erosion area was the largest (9.89%), followed by slight erosion and moderate erosion. (3) Socioeconomic impact, accompanied by natural environmental factors, was the main driving force underlying the change in soil erosion within the ecological restoration area. In particular, the socioeconomic factors of per capita forest area and land reclamation rate, as well as the natural environmental factor of terrain slope, significantly influenced soil erosion changes within the ecological restoration area.

    To test whether there are general patterns in biomass partitioning in relation to environmental variation when stand biomass is considered, we investigated biomass allocation in leaves, stems, and roots in China's forests using both the national forest inventory data (2004-2008) and our field measurements (2011-2012). Distribution patterns of leaf, stem, and root biomass showed significantly different trends according to latitude, longitude, and altitude, and were positively and significantly correlated with stand age and mean annual precipitation. Trade-offs among leaves, stems, and roots varied with forest type and origin and were mainly explained by stand biomass. Based on the constraints of stand biomass, biomass allocation was also influenced by forest type, origin, stand age, stand density, mean annual temperature, precipitation, and maximum temperature in the growing season. Therefore, after stand biomass was accounted for, the residual variation in biomass allocation could be partially explained by stand characteristics and environmental factors, which may aid in quantifying carbon cycling in forest ecosystems and assessing the impacts of climate change on forest carbon dynamics in China.

    Neural tube defects are largely preventable by the maternal periconceptual consumption of folic acid. The aim of this study was to examine the levels of synthetic folic acid in foods and the range of food stuffs with added folic acid available to consumers in Ireland at the current time. Three audits of fortified foods available in supermarkets in the Republic of Ireland were conducted. Researchers visited supermarkets and obtained folic acid levels from nutrition labels in 2004, 2008 and 2013/4. Levels were compared using MS Excel. The profile of foods fortified with folic acid in 2013/4 has changed since 2004. The percentage of foods fortified with folic acid has decreased as has the level of added folic acid in some food staples, such as fat/dairy spreads. Bread, milk and spreads no longer contain as much folic acid as previously (2004 and 2008). This may contribute to a decrease in folate intake and therefore may contribute to an increase in NTD rates. Research on current blood concentrations of folate status markers is now warranted. © The Author 2015. Published by Oxford University Press on behalf of Faculty of Public Health. All rights reserved.

    Because Vital Statistics data do not include information on Inuit identity in all jurisdictions, mortality rates cannot be calculated specifically for Inuit. However, Inuit in Canada are geographically concentrated--78% live in Inuit Nunangat, and 82% of the area's total population identify as Inuit. While there are limitations, geographic approaches can be employed to calculate mortality for the population of that area. The Vital Statistics Database (1994 to 2008) and population estimates were used to calculate age-standardized mortality rates (ASMRs) in five-year intervals around the 1996 and 2006 Census years. Mortality rates were calculated for 1- to 19-year-olds living in Inuit Nunangat and those living elsewhere in Canada. The ASMR in 2004-2008 for 1- to 19-year-olds in Inuit Nunangat was 188.0 deaths per 100,000 person-years at risk, five times the rate (35.3) elsewhere in Canada. The disparity had not narrowed over the previous decade. In Inuit Nunangat, injuries were responsible for 64% of deaths of children and teenagers, compared with 36% in the rest of Canada. The persistently high mortality rates for children and teenagers living in Inuit Nunangat, compared with the rest of Canada, are important in understanding the health and socio-economic situation of residents of this region.

    Full Text Available Abstract Background The HIV epidemic in Russia has increasingly involved reproductive-aged women, which may increase perinatal HIV transmission. Methods Standard HIV case-reporting and enhanced perinatal HIV surveillance systems were used for prospective assessment of HIV-infected women giving birth in St. Petersburg, Russia, during 2004-2008. Trends in social, perinatal, and clinical factors influencing mother-to-child HIV transmission stratified by history of injection drug use, and rates of perinatal HIV transmission were assessed using two-sided χ2 or Cochran-Armitage tests. Results Among HIV-infected women who gave birth, the proportion of women who self-reported ever using injection drugs (IDUs decreased from 62% in 2004 to 41% in 2008 (P P P P for trend Conclusions Reduced proportion of IDUs and improved clinical services among HIV-infected women giving birth were accompanied by decreased perinatal HIV transmission, which can be further reduced by increasing outreach and HIV testing of women before and during pregnancy.

    Epidemiologic and health impact studies are inhibited by the paucity of global, long-term measurements of the chemical composition of fine particulate matter. We inferred PM2.5 chemical composition at 0.1° × 0.1° spatial resolution for 2004-2008 by combining aerosol optical depth retrieved from the MODIS and MISR satellite instruments, with coincident profile and composition information from the GEOS-Chem global chemical transport model. Evaluation of the satellite-model PM2.5 composition data set with North American in situ measurements indicated significant spatial agreement for secondary inorganic aerosol, particulate organic mass, black carbon, mineral dust, and sea salt. We found that global population-weighted PM2.5 concentrations were dominated by particulate organic mass (11.9 ± 7.3 μg/m(3)), secondary inorganic aerosol (11.1 ± 5.0 μg/m(3)), and mineral dust (11.1 ± 7.9 μg/m(3)). Secondary inorganic PM2.5 concentrations exceeded 30 μg/m(3) over East China. Sensitivity simulations suggested that population-weighted ambient PM2.5 from biofuel burning (11 μg/m(3)) could be almost as large as from fossil fuel combustion sources (17 μg/m(3)). These estimates offer information about global population exposure to the chemical components and sources of PM2.5.

    Based on a pluridisciplinary research programme on New Caledonia's lagoon (2004-2008), this paper addresses economic, ecological and political issues in order to implement integrated coastal zone management (ICZM) in this French Pacific territory. The nickel mining industry constitutes the core of the re-balancing economic and social strategy between the Northern and Southern provinces. But major impacts on the coastal environment of metal-processing plants, harbours, and decades of mine exploitation have released a controversy. A short diachronic analysis suggests that such environmental concerns prompted the emergence of collective actions to among civil society, customary and institutional stakeholders. The inscription of New Caledonia lagoon and reef areas in the UNESCO World Heritage List in 2008 would be both an outcome and a catalyst of this on-going process. Looking beyond the reefs towards the mainland and watersheds for the construction of local socio-ecological systems, we assume that the current stakes could result in the initiation of ICZM in New Caledonia.

    This dissertation presents the results of a search for supersymmetry in protonantiproton collisions with a center of mass energy of 1.96 TeV studied with the Collider Detector at Fermilab. Our strategy is to select collisions with two photons in the nal state that have the properties of being the decays of very massive supersymmetric particles. This includes looking for large total energy from the decayed particles as well as for the presence of particles that leave the detector without interacting. We nd no events using 2.6 fb-1 of data collected during the 2004-2008 collider run of the Fermilab Tevatron which is consistent with the background estimate of 1.4 0.4 events. Since there is no evidence of new particles we set cross section limits in a gaugemediated supersymmetry model with X$\\tilde{o}$1→ eG, where the X$\\tilde{o}$1 and eG are the lightest neutralino and the gravitino (the lightest supersymmetric particle), respectively. We set limits on models as a function of the X$\\tilde{o}$1 mass and lifetime, producing the world's most sensitive search for X$\\tilde{o}$1 by excluding masses up to 149 GeV=c2 for X$\\tilde{o}$1 lifetimes much less than 1 ns.

    2011-12-01

    According to the Seventh National Forest Inventory (2004-2008), China's forests cover an area of 195.45 million ha, or 20.36% of the total land area. China has the most rapidly increasing forest resources in the world. However, China is also a country with serious forest pest problems. There are more than 8,000 species of potential forest pests in China, including insects, plant diseases, rodents and lagomorphs, and hazardous plants. Among them, 300 species are considered as economically or ecologically important, and half of these are serious pests, including 86 species of insects. Forest management and utilization have a considerable influence on the stability and sustainability of forest ecosystems. At the national level, forestry policies always play a major role in forest resource management and forest health protection. In this paper, we present a comprehensive overview of both achievements and challenges in forest management and insect pest control in China. First, we summarize the current status of forest resources and their pests in China. Second, we address the theories, policies, practices and major national actions on forestry and forest insect pest management, including the Engineering Pest Management of China, the National Key Forestry Programs, the Classified Forest Management system, and the Collective Forest Tenure Reform. We analyze and discuss three representative plantations— Eucalyptus, poplar and Masson pine plantations—with respect to their insect diversity, pest problems and pest management measures.

  11. Real Economic Convergence in Western Europe from 1995 to 2013

    Full Text Available The aim of the paper is to analyze the economic convergence of real per capita GDP in the Western European countries with two types of measurement methodology. The first is sigma convergence, based on the coefficient of variation of real per capita GDP. The second is beta convergence, absolute/unconditional and conditional, including economic and socio-political variables, based on the neoclassical growth theory. The hypothesis of the paper is that there has been real economic convergence in Western Europe in at least one analyzed sub-period. The relationships between selected macroeconomic variables and the rate of economic growth are econometrically tested. Both sigma and beta convergence are estimated for the period 1995-2013 and four sub-periods: 1995-2003, 2004-2013, pre-crisis sub-period 2004-2008 and the crisis sub-period 2009-2013. The empirical findings support the hypothesis of economic convergence, i.e. that the poorer countries tend to grow faster than the rich ones in per capita terms, for some periods. However, the countries had a tendency to diverge, confiriming the negative effects of the crisis on per capita GDP growth. Sigma convergence is consistent with beta convergence. According to the results, the half-life of real convergence may take from 12 to 1078 years. Significant dissimilarities between the growth patterns among individual countries show the considerable heterogeneity of growth, i.e. the convergence clubs.

  12. Race, space, place: notes on the racialisation and spatialisation of commercial sex work in Dubai, UAE.

    This paper focuses on the perceived racialisation and resultant spatialisation of commercial sex in Dubai. In recent years, the sex industry in Dubai has grown to include women from the Middle East, Eastern Europe, East Asia and Africa. With the increase in sex workers of different nationalities has come a form of localised racism that is embedded in structures and desires seen within specific locations. The physical spatialisation of sex work hinges on perceived race and produces distinct income generating potential for women engaged in the sex industry in Dubai. The social and physical topography of Dubai is important in marginalising or privileging these various groups of sex workers, which correlates race, space and place with rights and assistance. I begin with a description of the multidirectional flows of causality between race, space, place and demand. I then discuss how these various groups are inversely spatialised within the discourse on assistance, protection and rights. The findings presented here are based on ethnographic research conducted with transnational migrants in the UAE in 2004, 2008 and 2009.

    In this paper, a statistical procedure to construct a control chart for monitoring air quality (PM10) using functional data is proposed. A set of daily indices that represent the daily PM10 curves were obtained using Functional Principal Component Analysis (FPCA). By means of an iterative charting procedure, a reference data set that represented a stable PM10 process was obtained. The data were then used as a reference for monitoring future data. The application of the procedure was conducted using seven-year (2004-2010) period of recorded data from the Klang air quality monitoring station located in the Klang Valley region of Peninsular Malaysia. The study showed that the control chart provided a useful visualization tool for monitoring air quality and was capable in detecting abnormality in the process system. As in the case of Klang station, the results showed that with reference to 2004-2008, the air quality (PM10) in 2010 was better than that in 2009.

    the aim of this study was to report a ten years experience in the electronic medical record (EMR) use. An estimated 80% of healthcare transactions are still paper-based. an EMR system was built at the end of 1998 in an Italian tertiary care center to achieve total integration among different human and instrumental sources, eliminating paper-based medical records. Physicians and nurses who used EMR system reported their opinions. In particular the hospital activity supported electronically, regarding 4,911 adult patients hospitalized in the 2004- 2008 period, was examined. the final EMR product integrated multimedia document (text, images, signals). EMR presented for the most part advantages and was well adopted by the personnel. Appropriateness evaluation was also possible for some procedures. Some disadvantages were encountered, such as start-up costs, long time required to learn how to use the tool, little to no standardization between systems and the EMR technology. the EMR is a strategic goal for clinical system integration to allow a better health care quality. The advantages of the EMR overcome the disadvantages, yielding a positive return on investment to health care organization.

The purpose of this article is to highlight the evolution of FDI during 2000-2010 for 7countries of Central and Eastern Europe, precisely: Poland, Hungary, Czech Republic, Slovakia, Slovenia,Romania and Bulgaria (CEE-7 and the changes in the patterns of the FDI received. There are large differencesamong these countries regarding the investments received and we tried to identity the determinants thatcontributed to this uneven distribution of FDI .We analyzed the boom of FDI registered by these countriesduring 2000-2008 and the structure and dynamics of FDI after the break out of the crisis in 2008. FDI inCentral and Eastern Europe experienced a collapse in 2009, after 8 year of impressive increase, which followeda strong economic growth. Poland was the most attractive country of the region, even during the financial crisis.Romania and Bulgaria, which experienced an impressive increase of FDI during 2004-2008, were severelyaffected by the crisis. The collapse of FDI, which coincides with the economic recession, brought also somechanges in the structure and form of the FDI received.

    2009-07-01

    Pupal surveys of Aedes aegypti (L.) are useful indicators of risk for dengue transmission, although sample sizes for reliable estimations can be large. This study explores two methods for making pupal surveys more practical yet reliable and used data from 10 pupal surveys conducted in Puerto Rico during 2004-2008. The number of pupae per person for each sampling followed a negative binomial distribution, thus showing aggregation. One method found a common aggregation parameter (k) for the negative binomial distribution, a finding that enabled the application of a sequential sampling method requiring few samples to determine whether the number of pupae/person was above a vector density threshold for dengue transmission. A second approach used the finding that the mean number of pupae/person is correlated with the proportion of pupa-infested households and calculated equivalent threshold proportions of pupa-positive households. A sequential sampling program was also developed for this method to determine whether observed proportions of infested households were above threshold levels. These methods can be used to validate entomological thresholds for dengue transmission.

    Describing the development of PHC policy as promoted by Rosario Municipality (Argentina). A case-study was carried out during 2007 and 2008. Data was collected from secondary and primary sources (interviews, organisational census and observations). PHC development stages were identified by recognising the social norms which produced institutional change and transformation in municipal health services structure and health care and management models. The prevailing modes of governance in each stage were reconognised and characterised (clan, hierarchy and/or incentives). Four stages were identified between 1990 and 2008: 1990-1995/hierarchical mode: primary health care level organisation autonomied from hospitals. 1995-2000/ clan mode: developing of participatory managerial boards and community participation. 2000-2004/ clan mode: maturation of the "PHC movement" in competition with hospitals. 2004-2008/ clan-hierarchical mode: "movement's" crisis and constructions of norms tending towards enhancing an integrated network. Strengthening and empowering first-level health-care produced innovation favouring: the consolidation of a "PHC movement" having strong social commitment and improved services performance. The clan governance mode (regulating collective action via voluntary adhesion to shared values) was crucial for developing PHC between 1995 and 2004. Later on, the movement's fragmentation and the challenges of integrating the health system required developing hierarchical regulation mechanisms to complement the governance clan mode regulation.

    Multiplets, or groups of earthquakes with similar waveforms, are commonly observed at volcanoes, particularly those exhibiting unrest. Using triggered seismic data from the 1980-1986 Mount St. Helens (MSH) eruption, we have constructed a catalog of multiplet occurrence. Our analysis reveals that the occurrence of multiplets is related, at least in part, to the viscosity of the magma. We also constructed catalogs of multiplet occurrence using continuous seismic data from the 2004 eruption at MSH and 2007 eruption at Bezymianny Volcano, Russia. Prior to explosions at MSH in 2004 and Bezymianny in 2007, the multiplet proportion of total seismicity (MPTS) declined, while the average amplitudes and standard deviations of the average amplitude increased. The life spans of multiplets (time between the first and last event) were also shorter prior to explosions than during passive lava extrusion. Dome-forming eruptions that include a partially solidified plug, like MSH (1983-1986 and 2004-2008), often possess multiplets with longer life spans and MPTS values exceeding 50%. Conceptually, the relatively unstable environment prior to explosions is characterized by large and variable stress gradients brought about by rapidly changing overpressures within the conduit. We infer that such complex stress fields affect the number of concurrent families, MPTS, average amplitude, and standard deviation of the amplitude of the multiplets. We also argue that multiplet detection may be an important new monitoring tool for determining the timing of explosions and in forecasting the type of eruption.

Historical cohort study. Database linkage analysis. Live or stillborn deliveries. None. ART deliveries were linked to live birth or fetal death certificates. Length of gestation in 7,171 deliveries from fresh autologous ART cycles (2004-2008) was calculated and compared with that of SART CORS with the use of methods: M1 = outcome date - cycle start date; M2 = outcome date - transfer date + 17 days; and M3 = outcome date - transfer date + 14 days + day of transfer. Generalized estimating equation models were used to compare methods. Singleton and multiple deliveries were included. Overall prematurity (delivery 45% of deliveries and by more than 1 week in >22% of deliveries. Each method differed from each other. Estimates of preterm birth in ART vary depending on source of data and method of calculation. Some estimates may overestimate preterm birth rates for ART conceptions.

Low-birth-weight (LBW) children are not given BCG at birth in Guinea-Bissau; we conducted a randomized trial of BCG at birth (early BCG) vs delayed BCG. In the period 2004-2008 we recruited 2320 LBW children in Bissau. The children were visited at home at 2, 6, and 12 months of age. With a pretrial infant mortality of 250 per 1000, we hypothesized a 25% reduction in infant mortality for LBW children. Infant mortality was only 101 per 1000 during the trial. In the primary analysis, infant mortality was reduced insignificantly by 17% (mortality rate ratio [MRR] = .83 [.63-1.08]). In secondary analyses, early BCG vaccine was safe with an MRR of .49 (.21-1.15) after 3 days and .55 (.34-.89) after 4 weeks. The reduction in neonatal mortality was mainly due to fewer cases of neonatal sepsis, respiratory infection, and fever. The impact of early BCG on infant mortality was marked for children weighing <1.5 kg (MRR = .43 [.21-.85]) who had lower coverage for diphtheria-tetanus-pertussis vaccinations. Though early BCG did not reduce infant mortality significantly, it may have a beneficial effect in the neonatal period. This could be important for public health because BCG is often delayed in low-income countries.

    Full Text Available Intellectual capital is believed to be a contributing factor to companies’ performances and values. Several studies have been carried out on the influence of this capital to a company’s performance. However, the results still show some inconsistencies. Therefore, this study aims at re-evaluating the influence of intellectual capital through the addition of ownership structure as a control variable. Ownership structure needs to be controlled since, in Indonesia, it is likely to be concentrated due to the low rate of investor protection. Intellectual capital is measured by the VAICTM method, while the market performance is determined by the price to book value ratio. The sample is financial companies listed on Indonesian Stock Market during the 2004-2008 periods. The result of the analysis fails to support the hypothesis that intellectual capital is associated with firm’s values. The result probably is an indication that market is incapable to assess the value of a company’s intellectual capital because it has no standardized measure and the limited quantitative disclosure regarding intellectual capital.

    Starting point of the title memorandum is environmental sound operational management of the Ministry of Defence. In the memorandum 26 policy targets are formulated for the period 2004-2008 in the fields of climate and energy, noise, hazardous materials, environmental care, and biological diversity and nature. One of the projects concerns the participation in a wind turbine farm in the Dutch province Drenthe. [Dutch] Uitgangspunt van de nota is een milieuverantwoorde bedrijfsvoering. Na een grondige evaluatie van de Defensie Milieubeleidsnota (DMB) 2000 zijn in de DMB 2004 zo'n 26 doelstellingen geformuleerd tot en met het jaar 2008. De belangrijkste doelstellingen liggen op het gebied van klimaat en energie, geluid, gevaarlijke stoffen, afval, milieuzorg, en biodiversiteit en natuur. Een van de opvallendste projecten uit DMB 2004 is een windturbinepark in Drenthe. Defensie gaat daarbij deelnemen aan een provinciaal project op en naast het magazijnencomplex te Coevorden. Van acht a negen te plaatsen turbines, die elk 2 MegaWatt elektriciteit gaan opwekken, zal het ministerie van Defensie er zes voor zijn rekening nemen. Dat betekent een investering van ruim 19 miljoen euro. Deze investering wordt echter binnen tien jaar geheel terugverdiend. Het turbinepark past in de doelstelling dat bij Defensie, conform het Rijksbeleid, eind 2008 zo'n 75% van het elektriciteitsverbruik duurzaam wordt opgewekt.

    The present study examines the impact of Health Bucks, a farmers' market incentive programme, on awareness of and access to farmers' markets, and fruit and vegetable purchase and consumption in low-income New York City neighbourhoods. The evaluation used two primary data collection methods: (i) an on-site point-of-purchase survey of farmers' market shoppers; and (ii) a random-digit-dial telephone survey of residents in neighbourhoods where the programme operates. Additionally, we conducted a quasi-experimental analysis examining differential time trends in consumption before and after programme introduction using secondary Community Health Survey (CHS) data. New York City farmers' markets and communities. Farmers' market shoppers (n 2287) completing point-of-purchase surveys in a representative sample of New York City farmers' markets in 2010; residents (n 1025) completing random-digit-dial telephone survey interviews in 2010; and respondents (n 35 606) completing CHS interviews in 2002, 2004, 2008 and 2009. Greater Health Bucks exposure was associated with: (i) greater awareness of farmers' markets; (ii) increased frequency and amount of farmers' market purchases; and (iii) greater likelihood of a self-reported year-over-year increase in fruit and vegetable consumption. However, our CHS analysis did not detect impacts on consumption. While our study provides promising evidence that use of farmers' market incentives is associated with increased awareness and use of farmers' markets, additional research is needed to better understand impacts on fruit and vegetable consumption.

    This paper evaluates the productivity of municipal solid waste incinerators (MSWIs) by addressing the following questions: (1) to what extent should one further increase the production of power generation while maintaining the emission of noxious air at the current level?; (2) To what extent should one further decrease the emission of noxious air while maintaining the production of power generation at the current level?; and (3) To what extent should one increase the production of power generation and decrease the emission of noxious air simultaneously? To effectively address these questions to improve performance, the power generation and pollution control efficiencies are evaluated using TODEA (two-objective data envelopment analysis), as well as the overall efficiency evaluated using Tone's NS-overall model (slacks-based measure with non-separable desirable and undesirable outputs for evaluating overall efficiency). A MSWI case study in Taiwan with the panel data covering the period of 2004-2008 reveals that the power generation and overall efficiencies of build-operate-transfer are more efficient, on average, than those of public-own-operate and build-own-operate. However, the three building and operation types do not significantly differ in pollution control efficiency. (author)

    Emamectin benzoate has been used to treat sea lice, Lepeophtheirus salmonis, infestations on farmed Atlantic salmon, Salmo salar. Recent evidence suggests a reduction in effectiveness in some locations. A major challenge in the detection of tolerance emergence can be the typically low proportion of resistant individuals in a population during the early phases. The objectives of this study were to develop a method for determining differences in temporal development of tolerance between sea lice life stages and to explore how these differences might be used to improve the monitoring of treatment effectiveness in a clinical setting. This study examined two data sets based on records of sea lice abundance following emamectin benzoate treatments from the west coast of Scotland (2002-2006) and from New Brunswick, Canada (2004-2008). Life stages were categorized into two groups (adult females and the remaining mobile stages) to examine the trends in mean abundance and treatment effectiveness. Differences in emamectin benzoate effectiveness were found between the two groups by year and location, suggesting that an important part of monitoring drug resistance development in aquatic ectoparasites may be the need to focus on key life stages. © 2013 Blackwell Publishing Ltd.

    To describe volatile anesthesia (VA) use for pediatric asthma, including complications and outcomes. Retrospective cohort study. Children's hospitals contributing to the Pediatric Health Information System between 2004-2008. Children 2-18 years old with a primary diagnosis code for asthma supported with mechanical ventilation. Those treated with VA were compared to those not treated with VA or extracorporeal membrane oxygenation. Hospital VA use was grouped as none, 10% among intubated children. One thousand five hundred and fifty-eight patients received mechanical ventilation at 40 hospitals for asthma: 47 (3%) received VA treatment at 11 (28%) hospitals. Those receiving a VA were significantly less likely to receive inhaled b-agonists, ipratropium bromide, and heliox, but more likely to receive neuromuscular blocking agents than patients treated without VA. Length of mechanical ventilation, hospital stay (length of stay [LOS]) and charges were significantly greater for those treated with VA. Aspiration was more common but death and air leak did not differ. Patients at hospitals with VA use >10% were significantly less likely to receive inhaled b agonist, ipratropium bromide, methylxanthines, and heliox, but more likely to receive systemic b agonist, neuromuscular blocking agents compared to those treated at hospitals not using VA. LOS, duration of ventilation, and hospital charges were significantly greater for patients treated at centers with high VA use. Mortality does not differ between centers that use VA or not. Patients treated at centers with high VA use had significantly increased hospital charges and increased LOS.

    The study aims at describing the achievements and challenges of Leprosy control in Kaduna State using appropriate indicators. The study was a five year (2004-2008) retrospective review of the Leprosy records and annual reports of all the twenty three LGAs in Kaduna State. Various Leprosy indicators were calculated and presented in different graphic presentations. Focus group discussions were organised with the aim of identifying current challenges of Leprosy control in the State. There was a decline in the new Leprosy cases detected annually from 226 cases in 2004 to 140 cases in 2008. The prevalence rate ranged between 0.3-0.4 per 10,000 population within the five year period. The proportion of children among new cases dropped from 12% in 2004 to 5% in 2007 and increased to 9% in 2008. Grade 2 disability among new cases was very high (between 21%-27%) within the same period. Leprosy elimination target has been achieved in Kaduna State, but new cases with high proportion of children and WHO grade 2 disability were still been reported.

    Full Text Available Abstract Objectives: to measure food expenditure for children living in a favela in Rio de Janeiro, and compare this expenditure to the cost of a healthy diet, based on local prices. Methods: panel study, with three collection dates – 2004, 2008 and 2012 – conducted in children (5 to 9 years old in Manguinhos. Food prices were collected by way of a sample of local food stores in 2013 and deflated using indicators specific to food prices. Twenty-four hour diet recall, qualitative food frequency and the Brazilian food pyramid adequate for the age group were used to estimate the observed expenditure and the cost of a healthy diet. Results: in 2004, 49.2% of the families interviewed lived on less than US$1 per person/day and 9.7% in 2012.In the same period, the percentage of students eating free school meals dropped from 73% to 49%. Money spent on food was concentrated on sugary products (32.4% and snacks (12.5%. The estimated monthly cost of a healthy diet (US$142 was lower than the observed expenditure (US$176. Conclusions: increased purchasing power has not led to healthier food choices. The common belief that poor people choose food based on prices was rejected by the present study. Other factors certainly play an important role in food purchasing decisions.

    Data are presented for polychlorinated biphenyls (PCBs) and polybrominated diphenyls ethers (PBDEs) in passive air samplers (PAS) collected along a rural/remote latitudinal transect from southern UK to northern Norway during 2004-2008. This study is part of an ongoing campaign, using semipermeable membrane devices (SPMDs) as PAS over two year intervals since 1994. Absolute sequestered amounts of selected PCB congeners have decreased in a first order fashion between 1994-2008, with the average time of 8.4+/-3.2 years for atmospheric concentrations to decline by 50%. PCBs have continued to fractionate with latitude during this period. PBDE concentrations declined by 50% between 2000 and 2008 every 2.2+/-0.4 years. Results are discussed in terms of sources, long-range atmospheric transport, global fractionation, and clearance processes. It is concluded that the spatial and temporal trends in background European air mainly reflect the strength of primary diffusive emissions of these compounds and subsequently their ongoing declines. The direct evidence for this is similar rates of decline at all the sites; similar rates of decline for all congeners; no systematic change in the fractionation pattern since 1994. The latest results indicate a reduction in the rate of decline for PCBs (and hence in primary emissions).

    Training surgeons adds time to the duration of procedures and operation lists. This is not accounted for in the finance received to perform the operation by the hospital in the Payment by Results (PbR) system. To find out: 1. The effect on the duration of a procedure and the number of procedures performed on the list when a trainee is involved. 2. The percentage of orthopaedic cases with trainee involvement. 3. The effect of European working time directive (EWTD) on the trainee involvement in cases from theatre data in 2008 versus logbook data from 2004 - 2008. Data was taken from two different sources. Firstly, the Operating Room Information System (ORMIS) and patient operation notes. The second source was a consultant's logbook comprising 227 primary total knee replacements performed between 2004 and 2008. The data produced trends suggesting trainees took longer to perform procedures than consultants. In orthopaedic operations, 92% of cases had trainees present and of these 17% of cases were performed by trainees in 2008. Before the implementation of the EWTD, trainees performed more procedures when compared with current logbook data (38% versus 17% cases). Time taken by a trainee to perform the procedure under direct consultant supervision was significantly higher in comparison to procedures performed by a consultant alone (P = < 0.0001). Analysing the ORMIS and logbook data gave similar conclusions. Hospitals should be given financial recognition for training. In this debate, we should remain focused on the provision of quality training for the next generation of surgeons.

    Social dynamics within social participation is a crucial issue for the accomplishment of forest conservation. In order to contribute to this field, a study of 31 institutional and community organized actors' cooperative practices, within forest conservation processes in Paipa and Duitama, located at the oak forests conservation corridor Guantiva, La Rusia, Iguaque in Colombia, was made, applying Social Network Analysis (SNA). Particularly, this article inquiry is about models of participation of these actors within the period of 2004-2008, looking at their projects and actions as management practices of forest conservation. The research questions were how social participation is included and understood in the conservation of these oak forests, observing cooperative practices amongst this set of actors, at local level. The results are related with the structural patterns of co-participation established amongst these actors within each other's projects and actions and the impact of those in the aim of forest conservation at local level, regarding power relations and its impact on forest conservation.

    Markedly increased red meat consumption is a cancer risk factor, while dietary flavonoids may help prevent the disease. The purpose of this study was to investigate the associations of red meat and flavonoid consumption with cancer risk, based on data from 8024 subjects, drawn from the 2004-2008 Cancer Screening Examination Cohort of the Korean National Cancer Center. Hazard ratios (HRs) were obtained by using a Cox proportional hazard model. During the mean follow-up period of 10.1 years, 443 cases were newly diagnosed with cancer. After adjusting for age, there was a significant correlation between cancer risk and the daily intake of ≥43 g of red meat per day (HR 1.31; 95% CI 1.01, 1.71; p = 0.045), and total flavonoid intake tended to decrease cancer risk (HR 0.70; 95% CI 0.49, 0.99; highest vs. lowest quartile; p -trend = 0.073) in men. Following multivariable adjustment, there were no statistically significant associations between flavonoid intake and overall cancer risk in individuals with high levels of red meat intake. Men with low daily red meat intake exhibited an inverse association between flavonoid consumption and cancer incidence (HR 0.41; 95% CI 0.21, 0.80; highest vs. lowest; p -trend = 0.017). Additional research is necessary to clarify the effects of flavonoid consumption on specific cancer incidence, relative to daily red meat intake.

    Atmospheric tritium activity is measured regularly around Narora Atomic Power Station (NAPS) since gaseous waste, which contains tritium, is being released through a 145 m high stack at NAPS site. Atmospheric data collected during 2004-2008 shows a large variation of 3 H concentration in air, fluctuating in the range of ≤0.2-91.6 Bq m -3 . Significantly, higher tritium levels were measured in samples near the site boundary (1.6 km) of NAPS compared to off-site locations. The atmospheric dilution factor was found to be in the range of 1.1 x 10 -7 -7.3 x 10 -7 s m -3 . The scavenging ratio of NAPS site was found to be varying from 0.2 x 10 4 to 14.1 x 10 4 (Bq m -3 rain water per Bq m -3 air). The inhalation dose to a member of general public at different distances (1.6-30 km) from NAPS site was found to be ranged from 0.08-0.21 μSv year -1 . (author)

  19. Effects of wave energy converters on the surrounding soft-bottom macrofauna (west coast of Sweden).

    2010-06-01

    Offshore wave energy conversion is expected to develop, thus contributing to an increase in submerged constructions on the seabed. An essential concern related to the deployment of wave energy converters (WECs) is their possible impact on the surrounding soft-bottom habitats. In this study, the macrofaunal assemblages in the seabed around the wave energy converters in the Lysekil research site on the Swedish west coast and a neighbouring reference site were examined yearly during a period of 5 years (2004-2008). Macrobenthic communities living in the WECs' surrounding seabed were mainly composed by organisms typical for the area and depth off the Swedish west coast. At both sites the number of individuals, number of species and biodiversity were low, and were mostly small, juvenile organisms. The species assemblages during the first years of sampling were significantly different between the Lysekil research site and the nearby reference site with higher species abundance in the research site. The high contribution to dissimilarities was mostly due to polychaetes. Sparse macrofaunal densities can be explained by strong hydrodynamic forces and/or earlier trawling. WECs may alter the surrounding seabed with an accumulation of organic matter inside the research area. This indicates that the deployment of WECs in the Lysekil research site tends to have rather minor direct ecological impacts on the surrounding benthic community relative to the natural high variances.

    Sensorineural hearing loss (SNHL) is one of the major long term side effects from radiation therapy (RT) in nasopharyngeal cancer (NPC) patients. This study aims to review the incidences of SNHL when treating with different radiation techniques. The additional objective is to determine the relationship of the SNHL with the radiation doses delivered to the inner ear. A retrospective cohort study of 134 individual ears from 68 NPC patients, treated with conventional RT and IMRT in combination with chemotherapy from 2004-2008 was performed. Dosimetric data of the cochlea were analyzed. Significant SNHL was defined as > 15 dB increase in bone conduction threshold at 4 kHz and PTA (pure tone average of 0.5, 1, 2 kHz). Relative risk (RR) was used to determine the associated factors with the hearing threshold changes at 4 kHz and PTA. Median audiological follow up time was 14 months. The incidence of high frequency (4 kHz) SNHL was 44% for the whole group (48.75% in the conventional RT, 37% with IMRT). Internal auditory canal mean dose of > 50 Gy had shown a trend to increase the risk of high frequency SNHL (RR 2.02 with 95% CI 1.01-4.03, p = 0.047). IMRT and radiation dose limitation to the inner ear appeared to decrease SNHL

    We investigated the association of individual-level ambient exposure to black carbon (spatiotemporal model-based estimate for latitude and longitude of residential address) with individual, household, and census tract socioeconomic measures among a study sample comprised of 1757 US urban working class white, black and Latino adults (age 25–64) recruited for two studies conducted in Boston, MA (2003–2004; 2008–2010). Controlling for age, study, and exam date, the estimated average annual black carbon exposure for the year prior to study enrollment at the participants' residential address was directly associated with census tract poverty (beta = 0.373; 95% confidence interval (CI) 0.322, 0.423) but not with annual household income or education; null associations with race/ethnicity became significant only after controlling for socioeconomic position. - Highlights: • The study included 1757 black, Latino, and white working class adults in Boston, MA. • Census tract poverty was associated with annual average black carbon exposure. • Annual household income was not associated with black carbon exposure. • Individual-level education was not associated with black carbon exposure. • The observed socioeconomic patterns varied by race/ethnicity. - In a US multiethnic urban working adult population, exposure to black carbon was more strongly associated with census tract as compared to household- or individual-level socioeconomic measures

    Full Text Available SummaryObjectives:the aim of this study was to report a ten years experience in the electronic medical record (EMR use. An estimated 80% of healthcare transactions are still paper-based.Methods:an EMR system was built at the end of 1998 in an Italian tertiary care center to achieve total integration among different human and instrumental sources, eliminating paper-based medical records. Physicians and nurses who used EMR system reported their opinions. In particular the hospital activity supported electronically, regarding 4,911 adult patients hospitalized in the 2004- 2008 period, was examined.Results:the final EMR product integrated multimedia document (text, images, signals. EMR presented for the most part advantages and was well adopted by the personnel. Appropriateness evaluation was also possible for some procedures. Some disadvantages were encountered, such as start-up costs, long time required to learn how to use the tool, little to no standardization between systems and the EMR technology.Conclusion:the EMR is a strategic goal for clinical system integration to allow a better health care quality. The advantages of the EMR overcome the disadvantages, yielding a positive return on investment to health care organization.

    This article describes the prevalence of laryngeal pathology in a treatment-seeking population with dysphonia in the Flemish part of Belgium. Retrospective investigation. During a period of 5 years (2004-2008), data were collected from 882 patients who consulted with dysphonia at the ear, nose, and throat department of the University Hospital in Ghent (Belgium). Laryngeal pathology was diagnosed using videostroboscopy. Ages ranged from 4 years to 90 years. Functional voice disorders were most frequently diagnosed (30%), followed by vocal fold nodule (15%), and pharyngolaryngeal reflux (9%). The role of age, gender, and occupation was investigated. Pathologies were significantly more common in females than in males, representing 63.8% and 36.2% of the population, respectively. Professional voice users accounted for 41% of the workforce population, with teachers as main subgroup. In professional voice users, functional dysphonia occurred in 41%, vocal fold nodules in 15%, and pharyngolaryngeal reflux in 11%. Our data were compared with data from other countries. Functional voice disorders were overall the most common cause of voice disorders (except in childhood), followed by vocal fold nodules and pharyngolaryngeal reflux. Professional voice users accounted for almost one half of the active population, with functional voice disorders as the main cause of dysphonia.

    This study estimated the relative influence of age/generation and tenure on job satisfaction and workplace climate perceptions. Data from the 2004, 2008, and 2012 Veterans Health Administration All Employee Survey (sample sizes >100 000) were examined in general linear models, with demographic characteristics simultaneously included as independent variables. Ten dependent variables represented a broad range of employee attitudes. Age/generation and tenure effects were compared through partial η(2) (95% confidence interval), P value of F statistic, and overall model R(2). Demographic variables taken together were only weakly related to employee attitudes, accounting for less than 10% of the variance. Consistently across survey years, for all dependent variables, age and age-squared had very weak to no effects, whereas tenure and tenure-squared had meaningfully greater partial η(2) values. Except for 1 independent variable in 1 year, none of the partial η(2) confidence intervals for age and age-squared overlapped those of tenure and tenure-squared. Much has been made in the popular and professional press of the importance of generational differences in workplace attitudes. Empirical studies have been contradictory and therefore inconclusive. The findings reported here suggest that age/generational differences might not influence employee perceptions to the extent that human resource and management practitioners have been led to believe.

    The present paper describes the logistics of the 2004-2008 Australasian Level III Dosimetry Intercomparison. Dosimetric intercomparisons (or 'audits') can be used in radiotherapy to evaluate the accuracy and quality of radiation delivery. An intercomparison was undertaken in New Zealand and Australia to evaluate the feasibility and logistics of ongoing dosimetric intercomparisons that evaluate all steps in the radiotherapy treatment process, known as a 'Level III' intercomparison. The study commenced in 2002 with the establishment of a study team, definition of the study protocol, acquisition of appropriate equipment and recruitment of participating radiotherapy centres. Measurements were undertaken between October 2004 and March 2008, and included collation of data on time, costs and logistics of the study. Forty independent Australian and New Zealand radiotherapy centres agreed to participate. Measurement visits were made to 37 of these centres. Data is presented on the costs of the study and the level of support required. The study involved the participation of 16 staff at the study centre who invested over 4000 hours in the study, and of over 200 professionals at participating centres. Recommendations are provided for future phantom-based intercomparisons. It is hoped that the present paper will be of benefit to any centres or groups contemplating similar activities by identifying the processes involved in establishing the study, the potential hazards and pitfalls, and expected resource requirements.

    A secondary data analysis of a prospective cohort study was conducted to explore how different definitions of injury affect the results of risk factor analyses. Modern circus artists (n=1281) were followed for 828,547 performances over a period of 49 months (2004-2008). A univariate risk factor analysis (age, sex, nationality, artist role) estimating incidence rate ratios (IRR) with 95% confidence intervals (95% CI) was conducted using three injury definitions: (1) medical attention injuries, (2) time-loss injuries resulting in ≥1 missed performances (TL-1) and (3) time-loss injuries resulting in >15 missed performances (TL-15). Results of the risk factor analysis were dependent on the injury definition. Sex (females to male; IRR=1.13, 95% CI; 1.02-1.25) and age over 30 (30 years; IRR=1.37, 95% CI; 1.07-1.79) were risk factors for medical attention injuries only. Risk of injury for Europeans compared with North Americans was higher for TL-1 and TL-15 injuries compared with medical attention injuries. Finally, non-sudden load artists (low-impact acts) were less likely than sudden load artists (high-impact acts) to have TL-1 injuries, but the risk of medical attention injuries was similar. The choice of injury definition can have effects on the magnitude and direction of risk factor analyses. © 2010 John Wiley & Sons A/S.

    To examine the sources of family income dynamics leading to movement into and out of Medicaid expansion and subsidy eligibility under the Affordable Care Act. Survey of Income and Program Participation (SIPP): 1996, 2001, 2004, 2008 panels. Considering four broad subsidy eligibility categories for monthly Modified Adjusted Gross Income (MAGI) (400 percent FPL), I use duration analysis to examine determinants of movements between categories over the course of a year. Using detailed monthly data, I determine the members of tax-filing units and calculate an approximation of MAGI at the monthly level. The analysis sample is adults ages 22-64 years. Incomes are highly variable within a year, particularly at the lower end of the income distribution. Employment transitions, including transitions not involving a period of nonemployment, and family structure changes strongly predict sufficient income volatility to trigger a change in subsidy category. Income volatility arising from employment and family structure changes is likely to trigger changes in subsidy eligibility within the year, but the sources and effects of the volatility differ substantially depending on the individual's position in the income distribution. © Health Research and Educational Trust.

    The treatment of elderly cancer patients is complicated by many factors. We sought to assess the uptake and tolerance of chemotherapy among patients 75 years and older diagnosed with small cell lung cancer (SCLC) in years 2004-2008 in Alberta, Canada, and assess their survival. All patients who met the above criteria and had an oncologist-consult were included. Data were obtained from the Alberta Cancer Registry and chart review. A total of 171 patients were included in the study, 117 (68%) of whom began chemotherapy. Of those, 52% completed all cycles, 66% did not have any dose reductions, and 31% completed all cycles at the recommended dose. The risk of death for patients who did not complete all cycles of chemotherapy was 2.72 (95% CI: 1.52-4.87) and for those who completed all cycles but with a reduced dose was 1.02 (95% CI: 0.57-1.82) relative to those who completed chemotherapy at full dose after adjusting for several demographic/clinical factors. Our results suggest that a significant proportion of elderly patients are able to tolerate chemotherapy and receive a survival benefit from it while those who experience toxicity may receive a survival benefit from a reduction in chemotherapy dose as opposed to stopping treatment.

    The focus of water quality modeling of Korean streams needs to be shifted from dissolved oxygen to algae or organic matter. In particular, the structure of water quality models should be modified to simulate the biochemical oxygen demand (BOD), which is a key factor in calculating total maximum daily loads (TMDLs) in Korea, using 5-day BOD determined in the laboratory (Bottle BOD(5)). Considering the limitations in simulating organic matter under domestic conditions, we attempted to model total organic carbon (TOC) as well as BOD by using a watershed model. For this purpose, the Soil and Water Assessment Tool (SWAT) model was modified and extended to achieve better correspondence between the measured and simulated BOD and TOC concentrations. For simulated BOD in the period 2004-2008, the Nash-Sutcliffe model efficiency coefficient increased from a value of -2.54 to 0.61. Another indicator of organic matter, namely, the simulated TOC concentration showed that the modified SWAT adequately reflected the observed values. The improved model can be used to predict organic matter and hence, may be a potential decision-making tool for TMDLs. However, it needs further testing for longer simulation periods and other catchments.

    The present study aimed at assessing bioelectric activity and cognitive functions in the workers on the conversion project of the "Shelter" object (SO) of the Chernobyl nuclear power plant into an environmentally safe system. A total of 196 men were included and examined before (t0) and after (t1) working on the SO in the period 2004-2008. They underwent a qEEG and a battery of neuropsychological and psychiatric assessments. At t1, the organized type of qEEG shifted towards the disorganized one. An increase of spectral δ-power in the left frontotemporal area, of θ- and α-power in the left temporal area, with redistribution of α-activity to the front and reduction of dominant frequency in the left temporal area, were registered. Further, neurocognitive tests revealed the presence of mild cognitive disorders at t1. Interestingly, those subjects previously exposed to radiation with no consequences, were more resistant to these detrimental effects. Taken together, the disturbances observed may be considered as cognitive symptoms of a chronic fatigue syndrome resulting from the exposure to ionizing radiation. Simple and non-invasive assessments, such as those performed by us, may be helpful to detect early brain changes caused by the presence of radiological risk factors.

    Full Text Available This paper analyses the performances of lower-limb amputees in the 100, 200 and 400 m running events from the 2004, 2008 and 2012 Paralympic Games. In this paper, four hypotheses are pursued. In the first, it investigates whether the running performance of lower-limb amputees over three consecutive Paralympic Games has changed. In the second, it asks whether a bi-lateral amputee has a competitive advantage over a uni-lateral amputee. In the third, the effect of blade classification has been considered and we attempt to see whether amputees in various classifications have different level of performance. Finally, it is considered whether the final round of competition obtains different levels of performance in comparison to the qualification heats. Based on the outcomes of these investigations, it is proposed that future amputee-based running events should be undertaken with separate and not combined events for the T42, T43 and T44 classifications at the Paralympic Games.

    The Hudson Bay Lowlands (HBL) is the second largest boreal wetland ecosystem in the world and an important natural source of global atmospheric methane. We quantify the HBL methane emissions by using the GEOS-Chem chemical transport model to simulate aircraft measurements over the HBL from the ARCTAS and pre-HIPPO campaigns in May-July 2008, together with continuous 2004-2008 surface observations at Fraserdale (southern edge of HBL) and Alert (Arctic background). The difference in methane concentrations between Fraserdale and Alert is shown to be a good indicator of HBL emissions, and implies a sharp seasonal onset of emissions in late May (consistent with the aircraft data), a peak in July-August, and a seasonal shut-off in September. The model, in which seasonal variation of emission is mainly driven by surface temperature, reproduces well the observations in summer but its seasonal shoulders are too broad. We suggest that this reflects the suppression of emissions by snow cover and greatly improve the model simulation by accounting for this effect. Our resulting best estimate for HBL methane emissions is 2.3 Tg/a, several-fold higher than previous estimates (Roulet et al., 1994; Worthy et al., 2000).

    Pre-prepared commercial foods (convenience foods, CFs) are one aspect of modern dietary habits. The present paper examines the association between CF consumption and dietary quality or body weight status in a sample of German children and adolescents. Linear mixed-effect regression analyses using data from 586 participants (296 boys, 3-18 years) in the Dortmund Nutritional Anthropometric Longitudinally Designed Study, who yearly completed 1890 3-day dietary records and anthropometric measurements in 2004-2008, was used. CF intake (percent total food intake) showed no significant association with macronutrient intakes (%E), with exception of a significant positive association with polyunsaturated fatty acid (PUFA) intake (Ptrend with increased consumption of CF (P=0.0013). No significant association between baseline or change in consumption of CF and baseline or change in parameters of body weight (standard deviation score of body mass index (weight/height(2)) or percentage body fat (%BF) estimated from skinfolds) was found. Among boys, baseline consumption of high-ED-CF significantly predicted change in %BF during the study period (β 0.104, P=0.0098). Our results point to an impairment of dietary quality with high consumption of CF and to a small but positive association between consumption of high-ED-CF in boys and weight.

    Valuation of health effects of air pollution is becoming a critical component of the performance of cost-benefit analysis of pollution control measures, which provides a basis for setting priorities for action. Beijing has focused on control of transport emission as vehicular emissions have recently become an important source of air pollution, particularly during Olympic games and Post-games. In this paper, we conducted an estimation of health effects and economic cost caused by road transport-related air pollution using an integrated assessment approach which utilizes air quality model, engineering, epidemiology, and economics. The results show that the total economic cost of health impacts due to air pollution contributed from transport in Beijing during 2004-2008 was 272, 297, 310, 323, 298 million US (mean value), respectively. The economic costs of road transport accounted for 0.52, 0.57, 0.60, 0.62, and 0.58% of annual Beijing GDP from 2004 to 2008. Average cost per vehicle and per ton of PM 10 emission from road transport can also be estimated as 106 US /number and 3584 US $ t -1, respectively. These findings illustrate that the impact of road transport contributed particulate air pollution on human health could be substantial in Beijing, whether in physical and economic terms. Therefore, some control measures to reduce transport emissions could lead to considerable economic benefit.

    2011-01-01

    This paper evaluates the productivity of municipal solid waste incinerators (MSWIs) by addressing the following questions: (1) to what extent should one further increase the production of power generation while maintaining the emission of noxious air at the current level?; (2) To what extent should one further decrease the emission of noxious air while maintaining the production of power generation at the current level?; and (3) To what extent should one increase the production of power generation and decrease the emission of noxious air simultaneously? To effectively address these questions to improve performance, the power generation and pollution control efficiencies are evaluated using TODEA (two-objective data envelopment analysis), as well as the overall efficiency evaluated using Tone's NS-overall model (slacks-based measure with non-separable desirable and undesirable outputs for evaluating overall efficiency). A MSWI case study in Taiwan with the panel data covering the period of 2004-2008 reveals that the power generation and overall efficiencies of build-operate-transfer are more efficient, on average, than those of public-own-operate and build-own-operate. However, the three building and operation types do not significantly differ in pollution control efficiency. - Research highlights: → The MSWIs implemented by private sectors are more effective than that by public sectors. → Policy makers should pay more attention to the reduction of CO during waste incineration. → Three alternatives for improving the performance of MSWIs can be made available.

    The objective of this study is to explore the extent to which managed care market penetration in the United States is associated with the presence of chronic disease. Diabetes was selected as the chronic disease of interest due to its increasing prevalence as well as the disease management protocols that can lessen disease complications. We hypothesized that greater managed care market penetration would be associated with (1) lower prevalence of diabetes and (2) lower prevalence of diabetes-related comorbidities (DRCs) among diabetics. Data for this analysis came from two sources. We merged Medicare Advantage (MA) market penetration data from the Centers for Medicare and Medicaid Services (CMS) with data from the Medical Expenditure Panel Survey (MEPS) (2004-2008). Results suggest that county-level MA market penetration is not significantly associated with prevalence of diabetes or DRCs. That finding is quite interesting in that managed care market penetration has been shown to have an effect on utilization of inpatient services. It may be that managed care protocols do not offer the same benefits beyond the inpatient setting.

    Large scale investment in the National Rural Health Mission is expected to increase the utilization and reduce the cost of maternal care in public health centres in India. The objective of this paper is to examine recent trends in the utilization and cost of hospital based delivery care in the Empowered Action Group (EAG) states of India. The unit data from the District Level Household Survey 3, 2007-2008 is used in the analyses. The coverage and the cost of hospital based delivery at constant price is analyzed for five consecutive years preceding the survey. Descriptive and multivariate analyses are used to understand the socio-economic differentials in cost and utilization of delivery care. During 2004-2008, the utilization of delivery care from public health centres has increased in all the eight EAG states. Adjusting for inflation, the household cost of delivery care has declined for the poor, less educated and in public health centres in the EAG states. The cost of delivery care in private health centres has not shown any significant changes across the states. Results of the multivariate analyses suggest that time, state, place of residence, economic status; educational attainment and delivery characteristics of mother are significant predictors of hospital based delivery care in India. The study demonstrates the utility of public spending on health care and provides a thrust to the ongoing debate on universal health coverage in India.

  1. Agentive reflexive clitics and transitive 'se' constructions in Spanish

    2013-11-01

    Full Text Available This paper investigates the structure of transitive sentences that contain a non-doubling reflexive clitic such as Juan se lavó todos los platos and María se leyó un libro. Though these are traditionally labelled unselected (non-core agreeing datives or aspectual datives, I argue that this label obscures a relevant difference between two classes of constructions. agentive reflexive clitic (= ARC constructions are characterized by a uniform set of effects on the external argument (= it must be an agent and the aspectual interpretation of the VP (= it must be an accomplishment. On the other hand, transitive se clitic (= TSC constructions do not impose any type of uniform restrictions on the kind of external argument they take or on the aspectual interpretation of the VP. I propose that the difference between these two constructions may be captured by treating se in the ARC construction as the realization of a special vDO head, based on an idea in Folli & Harley (2005, while se in the TSC construction is generated in the complement position of the verb and incorporates into V, forming a complex predicate, following work by De Cuyper (2006, MacDonald (2004, 2008 and MacDonald & Huidobro (2010. It is shown that many of the empirical and theoretical disagreements that plague the literature on the role of non-doubling se in transitive sentences have a simple solution given the new division established here

    Few studies have investigated international variations in the gestational age (GA) distribution of births. While preterm births (22-36 weeks GA) and early term births (37-38 weeks) are at greater risk of adverse health outcomes compared to full term births (39-40 weeks), it is not known if countries with high preterm birth rates also have high early term birth rates. We examined rate associations between preterm and early term births and mean term GA by mode of delivery onset. We used routine aggregate data on the GA distribution of singleton live births from up to 34 high-income countries/regions in 1996, 2000, 2004, 2008 and 2010 to study preterm and early term births overall and by spontaneous or indicated onset. Pearson correlation coefficients were adjusted for clustering in time trend analyses. Preterm and early term births ranged from 4.1% to 8.2% (median 5.5%) and 15.6% to 30.8% (median 22.2%) of live births in 2010, respectively. Countries with higher preterm birth rates in 2004-2010 had higher early term birth rates (r > 0.50, P birth rates suggest that common risk factors could underpin shifts in the GA distribution. Targeting modifiable population risk factors for delivery before 39 weeks GA may provide a useful preterm birth prevention paradigm.

    Rosser, Timothy G.

    Civilian pilot training has followed a traditional path for several decades. With a potential pilot shortage approaching, ICAO proposed a new paradigm in pilot training methodology called the Multi-Crew Pilot License. This new methodology puts a pilot in the cockpit of an airliner with significantly less flight time experience than the traditional methodology. The purpose of this study was to determine to what extent gender, country of origin and pilot training methodology effect an aviation consumer's willingness to fly. Additionally, this study attempted to determine what emotions mediate a consumer's decision. This study surveyed participants from India and the United States to measure their willingness to fly using the Willingness to Fly Scale shown to be valid and reliable by Rice et al. (2015). The scale uses a five point Likert-type scale. In order to determine the mediating emotions, Ekman and Friesen's (1979) universal emotions, which are happiness, surprise, fear, disgust, anger, and sadness were used. Data were analyzed using SPSS. Descriptive statistics are provided for respondent's age and willingness to fly values. An ANOVA was conducted to test the first four hypotheses and Hayes (2004, 2008) bootstrapping process was used for the mediation analysis. Results indicated a significant main effect for training, F(1,972) = 227.76, p . .001, etap 2 = 0.190, country of origin, F(1, 972) = 28.86, p relationship between training and country of origin, and training. The findings of this study are important to designers of MPL training programs and airline marketers.

    Ganoderma sp. is an airborne fungal spore type known to trigger respiratory allergy symptoms in sensitive patients. Aiming to reduce the risk for allergic individuals, we analysed fungal spore circulation in Szczecin, Poland, and its dependence on meteorological conditions. Statistical models for the airborne spore concentrations of Ganoderma sp.—one of the most abundant fungal taxa in the area—were developed. Aerobiological sampling was conducted over 2004-2008 using a volumetric Lanzoni trap. Simultaneously, the following meteorological parameters were recorded: daily level of precipitation, maximum and average wind speed, relative humidity and maximum, minimum, average and dew point temperatures. These data were used as the explaining variables. Due to the non-linearity and non-normality of the data set, the applied modelling techniques were artificial neural networks (ANN) and mutlivariate regression trees (MRT). The obtained classification and MRT models predicted threshold conditions above which Ganoderma sp. appeared in the air. It turned out that dew point temperature was the main factor influencing the presence or absence of Ganoderma sp. spores. Further analysis of spore seasons revealed that the airborne fungal spore concentration depended only slightly on meteorological factors.

    Deep long-period (DLP) earthquakes are an enigmatic type of seismicity occurring near or beneath volcanoes. They are commonly associated with the presence of magma, and found in some cases to correlate with eruptive activity. To more thoroughly understand and characterize DLP occurrence near volcanoes in Washington and Oregon, we systematically searched the Pacific Northwest Seismic Network (PNSN) triggered earthquake catalog for DLPs occurring between 1980 (when PNSN began collecting digital data) and October 2009. Through our analysis we identified 60 DLPs beneath six Cascade volcanic centers. No DLPs were associated with volcanic activity, including the 1980-1986 and 2004-2008 eruptions at Mount St. Helens. More than half of the events occurred near Mount Baker, where the background flux of magmatic gases is greatest among Washington and Oregon volcanoes. The six volcanoes with DLPs (counts in parentheses) are Mount Baker (31), Glacier Peak (9), Mount Rainier (9), Mount St. Helens (9), Three Sisters (1), and Crater Lake (1). No DLPs were identified beneath Mount Adams, Mount Hood, Mount Jefferson, or Newberry Volcano, although (except at Hood) that may be due in part to poorer network coverage. In cases where the DLPs do not occur directly beneath the volcanic edifice, the locations coincide with large structural faults that extend into the deep crust. Our observations suggest the occurrence of DLPs in these areas could represent fluid and/or magma transport along pre-existing tectonic structures in the middle crust. ?? 2010 Elsevier B.V.

    Since 2004, the French National Reference Laboratory for classical swine fever (CSF) has conducted an annual proficiency test (PT) to evaluate the ability of local veterinary laboratories to perform real-time polymerase chain reaction (PCR) for CSF virus. The results of five years of testing (2004-2008) are described here. The PT was conducted under blind conditions on 20 samples. The same batch of samples was used for all five years. The number of laboratories that analysed the samples increased from four in 2004 to 13 in 2008. The results of the PT showed the following: cross-contamination between samples and deficiencies in RNA preparation can occur even in experienced laboratories; sample homogeneity should be checked carefully before selection; samples stored at-80 degrees C for several years remain stable; and poor shipment conditions do not damage the samples with regard to detection of CSF virus genome. These results will enable redesign of the panel to improve the overall quality of the PT, which will encourage laboratories to check and improve their PCR procedures and expertise. This is an excellent way to determine laboratory performance.

    The Atlantic Meridional Overturning Circulation (AMOC) is responsible for a variable and climatically important northward transport of heat. Using data from an array of instruments that span the Atlantic at 26°N, we show that the AMOC has been in a state of reduced overturning since 2008 as compared to 2004-2008. This change of AMOC state is concurrent with other changes in the North Atlantic such as a northward shift and broadening of the Gulf Stream and altered patterns of heat content and sea surface temperature. These changes resemble the response to a declining AMOC predicted by coupled climate models. Concurrent changes in air-sea fluxes close to the western boundary reveal that the changes in ocean heat transport and sea surface temperature have altered the pattern of ocean-atmosphere heat exchange over the North Atlantic. These results provide strong observational evidence that the AMOC is a major factor in decadal-scale variability of North Atlantic climate.

    Aim To present the activities of the Agency for Medicinal Products and Medical Devices in the first 5 years of its existence and to define its future challenges. Methods Main activities within the scope of the Agency as a regulatory authority were retrospectively analyzed for the period from 2004-2008. Data were collected from the Agency’s database and analyzed by descriptive statistics. Results The number of issued medicine authorizations rose from 240 in 2004 to 580 in 2008. The greatest number of new chemical and biological entities was approved in 2005. The greatest number of regular quality controls (n = 5833) and special quality controls was performed in 2008 (n = 589), while the greatest number of off-shelf quality controls (n = 132) was performed in 2007. The greatest number of medicine labeling irregularities was found in 2007 (n = 19) and of quality irregularities in 2004 (n = 9). The greatest number of adverse reactions was reported in 2008 (n = 1393). The number of registered medical devices rose from 213 in 2004 to 565 in 2008. Conclusion Over its 5 years of existence, the Agency has successfully coped with the constant increase in workload. In the future, as Croatia enters the European Union, the Agency will have to face the challenge of joining the integrated European regulatory framework. PMID:20401952

    To study the trend pattern of the incidence of thyroid cancer. We selected incident cases of thyroid cancer occurring in the Region of Murcia (Spain) in 1984-2008. The variables gathered were age, sex, date of diagnosis, and morphology. We calculated incidence rates and the annual percentage of change using Bayesian age-period-cohort models. During the study period, 1414 cases were diagnosed, representing an increase in adjusted rates from 2.9/100000 in 1984-1988 to 7.3 in 2004-2008. The incidence was 3.5 times higher in women than in men and the most frequent morphology was papillary carcinoma (67.7%). An increasing trend was found in both genders; these increments were more pronounced in papillary carcinoma. In women, the incidence increased with age, calendar year, and in those born in 1945-1963. The incidence of papillary microcarcinoma increased four-fold in women. Thyroid cancer used to be a rare cancer but has become an emerging tumor. The greatest changes were found in papillary thyroid cancer, including a gradual increase in the proportion of microcarcinoma. Copyright © 2014 SESPAS. Published by Elsevier Espana.

    Despite substantial progress in the delivery of HIV prevention programs, some communities continue to experience high rates of HIV infection. We report on temporal trends in HIV prevalence in pregnant women in a community in rural KwaZulu-Natal in South Africa. Annual, anonymous cross-sectional HIV sero-prevalence surveys were conducted between 2001 and 2013 among first visit prenatal clinic attendees. The time periods 2001 to 2003 were defined as pre-antiretroviral therapy (ART), 2004 to 2008 as early ART, and 2009 to 2013 as contemporary ART roll-out, to correspond with the substantial scale-up of ART program. Overall, HIV prevalence rose from 35.3% [95% confidence interval (CI): 32.3 to 38.3] pre-ART (2001-2003) to 39.0% (95% CI: 36.8 to 41.1) in the early ART (2004-2008) to 39.3% (95% CI: 37.2 to 41.4) in the contemporary ART (2009-2013) roll-out periods. In teenage women (age 20-24 and ≥ 25 years had a 1.7-fold (95% CI: 1.3-2.4; P = 0.001) and 3-fold (95% CI: 2.1 to 4.3; P age-disparate relationships, are needed to impact this HIV epidemic trajectory.

    Avian metapneumovirus (aMPV) causes upper respiratory tract infections in chickens and turkeys. Although the swollen head syndrome (SHS) associated with aMPV in chickens has been reported in Korea since 1992, this is the study isolating aMPV from chickens in this country. We examined 780 oropharyngeal swab or nasal turbinate samples collected from 130 chicken flocks to investigate the prevalence of aMPV and to isolate aMPV from chickens from 2004-2008. Twelve aMPV subtype A and 13 subtype B strains were detected from clinical samples by the aMPV subtype A and B multiplex real-time reverse transcription polymerase chain reaction (RRT-PCR). Partial sequence analysis of the G glycoprotein gene confirmed that the detected aMPVs belonged to subtypes A and B. Two aMPVs subtype A out of the 25 detected aMPVs were isolated by Vero cell passage. In animal experiments with an aMPV isolate, viral RNA was detected in nasal discharge, although no clinical signs of SHS were observed in chickens. In contrast to chickens, turkeys showed severe nasal discharge and a relatively higher titer of viral excretion than chickens. Here, we reveal the co-circulation of aMPV subtypes A and B, and isolate aMPVs from chicken flocks in Korea.

    Ca Mau at the southern tip of Vietnam supports a large area of mangroves and has a high value for biodiversity and scenic beauty. This area is affected by erosion along the East Sea and accretion along the Gulf of Thailand, leading to the loss of huge stretches of mangroves along the East Sea and, in some cases, loss of ecosystems services provided by mangroves. In this study, we used remotely sensed aerial (1953), Landsat (1979, 1988, and 2000) and SPOT (1992, 1995, 2004, 2008 and 2009, and 2011) images and the Digital Shoreline Analysis System (DSAS) to quantify the rate of mangrove shoreline change for a 58 yr period. There were 1129 transects sampled at 100 m intervals along the mangrove shoreline and two statistical methods, namely End Point Rate (EPR) and Linear Regression Rate (LRR), were used to calculate the rate of change of mangrove shorelines and distance from 1953 to 2011. The study confirms erosion and accretion respectively are significant at the Eastern and Western Sea sides of the Ca Mau tip. The East Sea side had a mean erosion LRR of 33.24 m yr-1. For the accretion trend at the Gulf of Thailand side averaged at rate of 40.65 m yr-1. The results are important in predicting changes of coastal ecosystem boundaries and enable advanced planning for specific sections of coastline, to minimize or neutralize losses, to inform provincial rehabilitation efforts and reduce threats to coastal development and human safety.

    Full Text Available Abstract Background Brucellosis is an endemic infection in Georgia. We conducted a review of patient records with a suspected or confirmed diagnosis of brucellosis over three decades at the central referral hospital for brucellosis cases, the Institute of Parasitology and Tropical Medicine (IPTM in Tbilisi. The purpose was to describe the demographic profile and clinical characteristics as well as diagnostic and treatment strategies in patients with brucellosis. Methods Data were abstracted from randomly selected patient records at the IPTM. In total, 300 records were reviewed from three time periods: 1970-73, 1988-89, and 2004-2008. Results The age distribution of patients shifted from a median age of 40 years in the first time period to 20 years in the third time period. Azeri ethnicity was an increasing proportion of the total number of cases. The frequency of relapsed infection was 14.7% (44 cases. A total of 50 patients received vaccine therapy, and although the vaccine produced immune responses, demonstrated by an increase in agglutination titers, it was not associated with improved outcome. Conclusion The demographics of brucellosis in Georgia fit a profile of persons that tend sheep. Osteoarticular complications were commonly detected, especially in children. The changing pattern of brucellosis in Georgia suggests clinicians should be updated about different trends in brucellosis in their country.

    2009-01-01

    NASA s Neutral Buoyancy Laboratory (NBL) contains a 6.2 million gallon, 12-meter deep pool where astronauts prepare for space missions involving space walks (extravehicular activity EVA). Training is conducted in a space suit (extravehicular mobility unit EMU) pressurized to 4.0 - 4.3 PSI for up to 6.5 hours while breathing a 46% NITROX mix. Since the facility opened in 1997, over 30,000 hours of suited training has been completed with no occurrence of decompression sickness (DCS) or oxygen toxicity. This study examines the last 5 years of astronaut suited training runs. All suited runs are computer monitored and data is recorded in the Environmental Control System (ECS) database. Astronaut training runs from 2004 - 2008 were reviewed and specific data including total run time, maximum depth and average depth were analyzed. One hundred twenty seven astronauts and cosmonauts completed 2,231 training runs totaling 12,880 exposure hours. Data was available for 96% of the runs. It was revealed that the suit configuration produces a maximum equivalent air depth of 7 meters, essentially eliminating the risk of DCS. Based on average run depth and time, approximately 17% of the training runs exceeded the NOAA oxygen maximum single exposure limits, with no resulting oxygen toxicity. The NBL suited training protocols are safe and time tested. Consideration should be given to reevaluate the NOAA oxygen exposure limits for PO2 levels at or below 1 ATA.

    Stressful parental (usually maternal) environments can dramatically influence expression of traits in offspring, in some cases resulting in phenotypes that are adaptive to the inducing stress. The ecological and evolutionary impact of such transgenerational plasticity depends on both its persistence across generations and its adaptive value. Few studies have examined both aspects of transgenerational plasticity within a given system. Here we report the results of a growth-chamber study of adaptive transgenerational plasticity across two generations, using the widespread annual plant Polygonum persicaria as a naturally evolved model system. We grew five inbred Polygonum genetic lines in controlled dry vs. moist soil environments for two generations in a fully factorial design, producing replicate individuals of each genetic line with all permutations of grandparental and parental environment. We then measured the effects of these two-generational stress histories on traits critical for functioning in dry soil, in a third (grandchild) generation of seedling offspring raised in the dry treatment. Both grandparental and parental moisture environment significantly influenced seedling development: seedlings of drought-stressed grandparents or parents produced longer root systems that extended deeper and faster into dry soil compared with seedlings of the same genetic lines whose grandparents and/or parents had been amply watered. Offspring of stressed individuals also grew to a greater biomass than offspring of nonstressed parents and grandparents. Importantly, the effects of drought were cumulative over the course of two generations: when both grandparents and parents were drought-stressed, offspring had the greatest provisioning, germinated earliest, and developed into the largest seedlings with the most extensive root systems. Along with these functionally appropriate developmental effects, seedlings produced after two previous drought-stressed generations had

    Amphibole has the capability of incorporating a wide variety of trace elements resulting from a range of magmatic processes. Prior studies have used trace elements such as Li and Cu in amphibole to investigate volatile mobility associated with magma ascent regarding the 2004-2008 eruption of Mount St. Helens (Rowe et al. 2008). In order to investigate magmatic processes associated with the 2004-2008 eruption of Mount St. Helens we have measured a range of fluid-mobile trace elements in conjunction with major element compositions of amphibole phenocrysts in dacite lava. Major elements and volatiles (Cl, F) were measured by electron microprobe analysis at Washington State University and trace elements (Li, Sc, Co, Cu, Zn, Sr, Y, Zr, Mo, Ag, Sn, Sb, Te, Ba, Ce, W, and Pb) were analyzed by laser ablation (LA)-ICP-MS at Oregon State University. Amphibole crystallization temperatures were calculated after Ridolfi et al. (2010). Core to rim transects were measured by electron microprobe to evaluate volatile concentrations and temperature profiles across individual phenocrysts. Core temperatures from 17 days and 226 days post eruption are consistently hotter than the rim temperatures 997 to 881 degrees C, respectively. Amphiboles from the end of the eruption (811 days post eruption) appear to be more complex, with phenocrysts having both increasing and decreasing temperatures toward the rims. The overall calculated temperature range of the amphiboles at the end of the eruption is 1022 to 919 degrees C. There is much diversity in the concentrations of Li and Cu within the phenocrysts in both the samples and throughout the eruption. Concentrations steadily increase in the beginning of the eruption then drop dramatically toward the middle, slowly increase toward the end eruption. Overall concentrations of Sr, Sb, Co, Sn, Mo, Ba, Ce, Sc, and Y do not change over the course of the eruption but do vary sample to sample. Preliminary data for Zn, Sb, Ag, and W suggest the

    Lava domes are frequently subjected to cyclic heating and pressurisation, which may weaken the dome rocks, leading to renewed extrusion, explosions or collapse. These heating and loading cycles can be recreated in the laboratory, allowing the level of crack damage caused by these cycles to be established through analysing elastic moduli. Acoustic emissions (AEs) indicate the timing of cracking, and can also be used to interpret precursory seismicity for eruption prediction. Experiment samples are from Mount St. Helens, USA: 3 dacites from the Pine Creek eruptive period (2.9-2.55 ka), a Castle Creek age basalt (2.55-1.895 ka), and 4 dacites from the 2004-2008 eruption. Each sample was cut into several cylindrical cores (25 mm diameter and 62.5-70 mm long). Some samples were then heated and cooled at 1˚C/ minute to a target temperature of 600o C or 900o C, and held for 2 hours to achieve thermal equilibrium. This heating can cause cracking due to contrasts in thermal expansion of different minerals. Dynamic elastic moduli were calculated for each sample using ultrasonic wave velocity, density and porosity for later comparison to static elastic moduli gathered during deformation. One core of each sample was loaded to failure in uniaxial compression in order to find the short term strength of the sample. For all cyclic loading tests, conducted on pre-heated and unheated cores, samples were loaded at 10-5 s-1 strain rate then unloaded to 5MPa. Subsequent cycles had an increasing peak load. Most had the same rate for unloading, with a few samples unloaded instantaneously. Axial, radial and volumetric strain were determined from the recorded displacement throughout the experiment and used with the axial stress measurements to calculate static elastic moduli. Samples loaded to failure with no cycling generally failed at higher stresses than their cyclically loaded counter-parts, whilst rapid unloading increased their strength.

    Urinary incontinence (UI) is common and the relationship among its subtypes complex. Our objective was to describe the natural history and predictors of the incontinence subtypes stress, urgency, and mixed, in middle-aged and older US women. We tested our hypothesis that UI subtype history predicted future occurrence, evaluating subtype incidence/remission over multiple time points in a stable cohort of women. We analyzed longitudinal urinary incontinence data in 10,572 community-dwelling women aged ≥50 in the 2004-2010 Health and Retirement Study. Mixed, stress, and urgency incontinence prevalence (2004, 2006, 2008, 2010) and 2-year cumulative incidence and remissions (2004-2006, 2006-2008, 2008-2010) were estimated. Patient characteristics and incontinence subtype status 2004-2008 were entered into a multivariable, transition model to determine predictors for incontinence subtype occurrence in 2010. The prevalence of each subtype in this population (median age 63-66) was 2.6-8.9 %. Subtype incidence equaled 2.1-3.5 % and remissions for each varied between 22.3 and 48.7 %. Incontinence subtype incidence predictors included ethnicity/race, age, body mass index, and functional limitations. Compared with white women, black women had decreased odds of incident stress incontinence and Hispanic women had increased odds of stress incontinence remission. The age range 80-90 and severe obesity predicted incident mixed incontinence. Functional limitations predicted mixed and urgency incontinence. The strongest predictor of incontinence subtype was subtype history. The presence of the respective incontinence subtypes in 2004 and 2006 strongly predicted 2010 recurrence (odds ratio [OR] stress incontinence = 30.7, urgency OR = 47.4, mixed OR = 42.1). Although the number of remissions was high, a previous history of incontinence subtypes predicted recurrence. Incontinence status is dynamic, but tends to recur over the longer term.

    Motor vehicle crashes involving rural drivers aged 75 years and over are more than twice as likely to result in a serious or fatal injury as those involving their urban counterparts. The current study examined some of the reasons for this using a database of police-reported crashes (2004-2008) to identify the environmental (lighting, road and weather conditions, road layout, road surface, speed limit), driver (driver error, crash type), and vehicle (vehicle age) factors that are associated with the crashes of older rural drivers. It also determined whether these same factors are associated with an increased likelihood of serious or fatal injury in younger drivers for whom frailty does not contribute to the resulting injury severity. A number of environmental (i.e., undivided, unsealed, curved and inclined roads, and areas with a speed limit of 100km/h or greater) and driver (i.e., collision with a fixed object and rolling over) factors were more frequent in the crashes of older rural drivers and additionally associated with increased injury severity in younger drivers. Moreover, when these environmental factors were entered into a logistic regression model to predict whether older drivers who were involved in crashes did or did not sustain a serious or fatal injury, it was found that each factor independently increased the likelihood of a serious or fatal injury. Changes, such as the provision of divided and sealed roads, greater protection from fixed roadside objects, and reduced speed limits, appear to be indicated in order to improve the safety of the rural driving environment for drivers of all ages. Additionally, older rural drivers should be encouraged to reduce their exposure to these risky circumstances. Copyright © 2012 Elsevier Ltd. All rights reserved.

    Canine distemper virus (CDV) infects a variety of carnivores, including wild and domestic Canidae. Genetic/antigenic heterogeneity has been observed among the various CDV strains, notably in the haemagglutinin (H) gene, that appears as a good target to gather epidemiological information. Based on sequence analysis of the H gene, wild-type CDV strains cluster into distinct geographic lineages (genotypes), irrespective of the species of isolation. The sequence of the H gene of 28 CDV strains detected from both vaccinated and non-vaccinated breeding foxes, raccoon dogs and minks from different geographical areas of China during the years 2004-2008 was determined. All the CDV strains but two (strains HL and HLJ2) were characterized as Asia-1 genotype and were highly similar to each other (96.2-99.7% at the amino acid [aa] level) and to other Asia-1 strains (96.1-99.5% aa) previously detected in China. The CDV strains HL and HLJ2 were both collected from foxes in Heilongjiang province in 2005. Strain HL resembled CDVs of the Arctic genotype (GR88-like) and displayed high aa identity (98.0%) to the Chinese canine strain Liu. By converse, strain HLJ2 was barely related to CDVs of the Asia-2 genotype (88.7-90.3% aa identity), and could represent a novel CDV genotype, tentatively proposed as Asia-3. These results suggest that at least three different CDV genotypes, distantly related (81.8-91.6% aa identity) to the vaccine strains, Onderstepoort-like (America-1 genotype), are currently circulating in breeding foxes, raccoon dogs and minks in China, and that the genotype Asia-1 is predominant. Whether the diversity between wild-type CDVs and the vaccine strains may affect, to some extent, the efficacy of the vaccines deserves further investigations.

    In Nigeria, infertility is a social for the childless couple due to the high premium placed on propagating oneself. To determine the pattern of infertility among women attending the gynaecological clinic of university of Nigeria Teaching Hospital, Enugu and to examine the outcome of management. A descriptive retrospective design study based on findings from the folders of infertile couples presenting at the gynaecological clinic of University of Nigeria Teaching Hospital over a five year period (2004 - 2008). The data were collected from all documented and laboratory findings. The data extracted from the case records were the socio-demographic characteristics of the patients, the type of infertility whether primary or secondary, the causes, and the treatment in the years under review. The outcome of management was also evaluated. These were analyzed using SPSS 12.0.1 for window version. The mean age of the women was 34.1 +/- 4.9 range 21 - 46) years. The prevalence of infertility was 5.5% of all outpatient gynaecological consultations. The cause of infertility could not be determined in 39.4% of cases, female factors were identified as the sole causes in 28.7% of cases, male factors as sole causes in 11.5% of cases, and combined male/female factors in 20.4% of cases. Secondary infertility accounted for 76.8% of infertility and primary infertility 23.2%. The age of the women and the educational level did not significantly influence the type of infertility the women presented with (P > 0.05). Tubal factor was identified in majority of cases and pregnancy was recorded in only 17.0% of the women. Secondary infertility is more prevalent in Enugu with tubal factor accounting for majority of the cases with identifiable causes. The outcome of treatment of infertility is poor. There is need to improve infertility diagnostic and treatment facilities and approaches in Enugu, Nigeria.

    Extended-spectrum β-lactamases (ESBLs) are increasingly prevalent in Enterobacter spp., posing a challenge to the treatment of infections caused by this microorganism. The purpose of this retrospective study was to evaluate the prevalence, risk factors, and clinical outcomes of inpatients with bacteremia caused by ESBL and non ESBL-producing Enterobacter spp. in a tertiary hospital over the period 2004-2008. The presence of blaCTX-M, blaTEM, blaSHV, and blaPER genes was detected by polymerase chain reaction (PCR) and nucleotide sequence analysis. Genetic similarity between strains was defined by pulsed-field gel electrophoresis (PFGE). Enterobacter spp. was identified in 205 of 4907 of the patients who had positive blood cultures during hospitalization. Of those cases, 41 (20%) were ESBL-producing Enterobacter spp. Nosocomial pneumonia was the main source of bacteremia caused by ESBL-producing Enterobacter spp. The presence of this microorganism was associated with longer hospital stays. The ESBL genes detected were: CTX-M-2 (23), CTX-M-59 (10), CTX-M-15 (1), SHV-12 (5), and PER-2 (2). While Enterobacter aerogenes strains showed mainly a clonal profile, Enterobacter cloacae strains were polyclonal. Although no difference in clinical outcomes was observed between patients with infections by ESBL-producing and non-ESBL-producing strains, the detection of ESBL in Enterobacter spp. resulted in the change of antimicrobials in 75% of cases, having important implications in the decision-making regarding adequate antimicrobial therapy.

    Intimate partner violence (IPV) is a major problem that could affect reproductive decision making. The aim of this study is to examine the association between IPV and contraceptive use and assess whether the association varies by receipt of prenatal birth control counseling and race/ethnicity. This study analyzed the 2004-2008 national Pregnancy Risk Assessment Monitoring System (PRAMS) that included 193,310 women with live births in the United States. IPV was determined by questions that asked about physical abuse by a current or former partner in the 12 months before or during pregnancy. The outcome was postpartum contraceptive use (yes vs. no). Multiple logistic regression analyses were conducted to assess the influence of experiencing IPV at different periods (preconception IPV, prenatal IPV, both preconception and prenatal IPV, preconception and/or prenatal IPV). Data were stratified to assess differential effects by race/ethnicity and receipt of birth control counseling. Approximately 6.2% of women reported IPV, and 15.5% reported no postpartum contraceptive use. Regardless of the timing of abuse, IPV-exposed women were significantly less likely to report contraceptive use after delivery. This was particularly true for Hispanic women who reported no prenatal birth control counseling and women of all other racial/ethnic groups who received prenatal birth control counseling. IPV victimization adversely affects the use of contraceptive methods following delivery in women with live births. Birth control counseling by health providers may mitigate these effects; however, the quality of counseling needs further investigation. Better integration of violence prevention services and family planning programs is greatly needed. Consistent with national recommendations by the U.S. Preventive Service Task Force, clinicians and public health workers are strongly encouraged to screen for IPV. Health providers should educate women on effective contraceptive options and

    Emergency presentation of rectal cancer carries a relatively poor prognosis, but the roles and interactions of causative factors remain unclear. We describe an innovative statistical approach which distinguishes between direct and indirect effects of a number of contextual, patient and tumour factors on emergency presentation and outcome of rectal cancer. All patients diagnosed with rectal cancer in Ireland 2004-2008 were included. Registry information, linked to hospital discharge data, provided data on patient demographics, comorbidity and health insurance; population density and deprivation of area of residence; tumour type, site, grade and stage; treatment type and optimality; and emergency presentation and hospital caseload. Data were modelled using a structural equation model with a discrete-time survival outcome, allowing us to estimate direct and mediated effects of the above factors on hazard, and their inter-relationships. Two thousand seven hundred and fifty patients were included in the analysis. Around 12% had emergency presentations, which increased hazard by 80%. Affluence, private patient status and being married reduced hazard indirectly by reducing emergency presentation. Older patients had more emergency presentations, while married patients, private patients or those living in less deprived areas had fewer than expected. Patients presenting as an emergency were less likely to receive optimal treatment or to have this in a high caseload hospital. Apart from stage, emergency admission was the strongest determinant of poor survival. The factors contributing to emergency admission in this study are similar to those associated with diagnostic delay. The socio-economic gradient found suggests that patient education and earlier access to endoscopic investigation for public patients could reduce emergency presentation. © 2016 UICC.

    Full Text Available Background: Colorectal cancers often arise from benign polyps. Adenomatous polyps and serrated polyps progress step by step to adenocarcinoma and change into malignant cancers. Genetic and epigenetic changes have correlation with specific stages of polyp-adenocarcinoma progression and colorectal cancer histopathological changes. Aims: In this study we used immunohistochemistry (IHC staining in sporadic colorectal polyps to assay functional status of MLH1, MSH2, MSH6, and PMS2 proteins, to track genetic/epigenetic roles of this issue in our patients. Materials and Methods: In this cross-sectional study we assessed all patients who were admitted with sporadic colorectal polyps and underwent polypectomy in endoscopy department during 2004-2008. Result: IHC results were abnormal in 6.8% cases for MLH1, in 4.5% cases for MSH2, in 3% for MSH6, and in 4.8% for PMS2. In all cases with abnormal PMS2, MLH1 was also reported as abnormal. Same results were reported for abnormal MSH2, which is accompanied with abnormal MSH6 in all cases (P values < 0.001. There is no significant difference between IHC staining results, gender, dysplasia grade, adenomatous type, and invasion. On the other hand, there was significant difference between IHC staining results, polyp location, and mean age of patients. The same significant difference was between adenomatous polyps and serrated adenoma polyps by MLH1 and PMS2 (P values < 0.05. Conclusion: According to our findings, maybe MMR dysfunction is the cause of sporadic colorectal polyps in younger age and its increasing risk of dysplasia progression and malignancy progression is only in serrated adenoma. Sporadic polyps in left colon had a higher risk to progress to malignancies, and abnormal IHC staining for MLH1 and PMS2 in serrated polyps is much more than in other adenomatous polyps.

    The main aim of the New-type Rural Cooperative Medical System (NRCMS) put into effect in 2003 was to reduce financial barriers in accessing health care services among vulnerable populations. The aim of this study was to assess the association between NRCMS and income related inequality in hospital utilization among rural inhabitants in Jiangxi Province, China. A multistage stratified random cluster sampling method was adopted to select 1838, 1879, and 1890 households as participants in 2003/2004, 2008 and 2014, respectively. The Erreygers Concentration index (EI) of two measures of hospital inpatient care including admission to hospital and hospital avoidance, were calculated to measure income-related inequality. The decomposition of the EI was performed to characterize the contributions of socioeconomic and need factors to the measured inequality. An affluent-focused (pro-rich) inequity was observed for hospital admission adjusting for need factors over time. The level of inequity for hospital admission decreased dramatically, while hospital avoidance decreased marginally, and with a high value (EI, -0.0176) in 2008. The implementation of the NRCMS was associated with decreased inequity in 2008 and in 2014, but the associations were limited. Income contributed the most to the inequality of hospital utilization each year. The coverage of the NRCMS expanded to cover nearly all rural inhabitants in Jiangxi province by 2014 and was associated with a very small reduction in inequalities in admission to hospital. In order to increase equitable access to health care, additional financial protections for vulnerable populations are needed. Improving the relatively low level of medical services in township hospitals, and low rate of reimbursement and financial assistance with the NRCMS is recommended. © The Author 2017.

    Full Text Available The importance of estimation of a firm's probability of default increased significantly during the economic and financial crisis for financial institutions, which can be explained by the fact that the share of nonperforming loans increased in this period. The probability of default can be estimated with structural models, which have on base the methodology developed by Merton (1974, methodology used by Moody's Corporation (known as KMV Merton model. The aim of this study is to estimate the probability of default of companies listed on Bucharest Stock Exchange using this methodology. This approach was widely used in the literature by many researchers (i.e., Kealhofer and Kurbat (2000, Crosbie and Bohn (2002, Duffie and Wang (2004, Bharath and Shumway (2004, 2008. In Romania this methodology was empirically tested by Codirlaşu (2007, who estimated using Merton's methodology the probability of default of companies listed on the Bucharest Stock Exchange, respectively by Bobircă et al. (2008, where the probabilities of default were estimated in case of 42 companies listed on the Bucharest Stock Exchange for 2000-2008 time period. In this paper we used Merton's model, which assumes that a company defaults if the value of its assets is less than the promised dept repayment at time T. The process of estimating the probability of default starts from the following firm specific variables: the market value of the firm's assets, the share prices, the value of the liabilities and the risk-free rate. The analyzed period is 2003-2010, containing the economic and financial crisis period, too. Analyzing the financial statements of the companies listed on the Bucharest Stock Exchange, we determined the input parameters of the model and calculated the quarterly probabilities of default of each analyzed company. According to our results the probabilities of default have a reduced value in the majority of the cases.

    Due to the increasing urbanization, people spend more and more time in cities. Because of that fact during the last century the human bioclimatological approach had an important influence on the applied urban bioclimatology. The aim of the study was to analyze chosen thermal bioclimatic conditions in urban area of Upper Silesian Industrial Region in connection with the atmospheric circulation and air masses. The study was focused on the thermal conditions that are important for the bioclimatological research on human thermal comfort. They were the basis for making study on how to show the influence of the air masses and circulations types on frequency and variability of the chosen bioclimate indexes. That research was based on data (2004 - 2008) acquired by the Silesian University (Faculty of Earth Sciences) meteorological station located in the city of Sosnowiec (50°17'N, 19°08'E, h=263 m a.s.l.). The temperature measurements were made automatically every 10 minutes on the 2 meters above the ground level. Previous research showed that the station is a good representation of the local urban climate conditions in Upper Silesian Industrial Region. In the study the following air temperatures were taken into consideration: average day temperature, maximum day temperature, minimum day temperature and the average air temperature at 12 UTC. They were associated with atmospheric circulation types and masses typical for the region. Using the data mentioned above I conducted a classification to divide days into following objective categories: cool, cold, comfortable, hot, warm and very hot in the seasonal depiction. The final stage of the work was to find the answer to the following question: "When and how do the strong air masses and air circulations types modify bioclimatic conditions in the study area?" Answer to that question together with further results of the research will be presented on my poster.

    The objective of this study is to estimate the prevalence of congenital heart defects (CHD) in the Comunitat Valenciana (CV) in children less than one year old and identify whether there are temporal and geographic variations within this prevalence. The minimum basic data set from hospital discharge reports was used to select patients, who were born between 1999-2008, were less than one year old, and who lived in the CV with at least one hospital admission in which the primary diagnosis and/or any of the events were coded as CHD (codes 745-747 of the International Classification of Diseases 9th Revision Clinical Modification). The first hospital discharge report with CHD was selected, using the health card number to detect duplication. The prevalence and 95% confidence intervals were calculated, and the prevalence ratio (PR) and smoothed PR was obtained for each municipality to identify geographic patterns. In the period 1999-2008 there were 6.377 patients younger than one year with some CHD, representing the 43.2% of cases of congenital anomalies. The prevalence was 134.3 per 10.000 live births (95% CI: 131.1-137.6). There was a significant increase in the prevalence, from 115.8 in the 1999-2003 period to 149.5 in the 2004-2008 period. A higher risk was identified in the north of the CV, and in some municipalities of the province of Alicante, in the south. The observed increase in CHD agrees with the findings in other countries and it can be explained, at least in part, by improved diagnostic techniques. The geographic pattern identified requires a more detailed analysis that could explain the geographic variations found. Copyright © 2012 Asociación Española de Pediatría.

    Full Text Available 16S rRNA methylase and QepA, a fluoroquinolone efflux pump, are new mechanisms of resistance against aminoglycosides and fluoroquinolone, respectively. One of 16S rRNA methylase genes, rmtB, was found to be associated with qepA, were both located on the same transposable element. In this study, we intended to determine the current prevalence and characteristics of the 16S rRNA methylase genes and qepA, and to study the association between rmtB and qepA. A total of 892 Escherichia coli isolates were collected from various diseased food-producing animals in China from 2004-2008 and screened by PCR for 16S rRNA methylase genes and qepA. About 12.6% (112/892 and 0.1% (1/892 of isolates that were highly resistant to amikacin were positive for rmtB and armA, respectively. The remaining five 16S rRNA methlyase genes were not detected. Thirty-six (4.0% strains carried qepA. About 32.1% of rmtB-positive strains harbored qepA, which was not detected in rmtB-negative strains. Most strains were clonally unrelated, while identical PFGE profiles of rmtB-positive isolates were found in the same farm indicating clonal transmission. Conjugation experiments showed that rmtB was transfered to the recipients, and qepA also cotransfered with rmtB in some cases. The spread of E. coli of food animal origin harboring both rmtB and qepA suggests that surveillance for antimicrobial resistance of animal origin as well as the study of the mechanisms of resistance should be undertaken.

    Zooplankton species diversity and distribution are important measures of environmental change in the Arctic Ocean, and may serve as 'rapid-responders' of climate-induced changes in this fragile ecosystem. The scarcity of taxonomists hampers detailed and up-to-date monitoring of these patterns for the rarer and more problematic species. DNA barcodes (short DNA sequences for species recognition and discovery) provide an alternative approach to accurate identification of known species, and can speed routine analysis of zooplankton samples. During 2004-2008, zooplankton samples were collected during cruises to the central Arctic Ocean and Chukchi Sea. A ˜700 base-pair region of the mitochondrial cytochrome oxidase I (mtCOI) gene was amplified and sequenced for 82 identified specimens of 41 species, including cnidarians (six hydrozoans, one scyphozoan), arthropod crustaceans (five amphipods, 24 copepods, one decapod, and one euphausiid); two chaetognaths; and one nemertean. Phylogenetic analysis used the Neighbor-Joining algorithm with Kimura-2-Parameter (K-2-P) distances, with 1000-fold bootstrapping. K-2-P genetic distances between individuals of the same species ranged from 0.0 to 0.2; genetic distances between species ranged widely from 0.1 to 0.7. The mtCOI gene tree showed monophyly (at 100% bootstrap value) for each of the 26 species for which more than one individual was analyzed. Of seven genera for which more than one species was analyzed, four were shown to be monophyletic; three genera were not resolved. At higher taxonomic levels, only the crustacean order Copepoda was resolved, with bootstrap value of 83%. The mtCOI barcodes accurately discriminated and identified known species of 10 taxonomic groups of Arctic Ocean holozooplankton. A comprehensive DNA barcode database for the estimated 300 described species of Arctic holozooplankton will allow rapid assessment of species diversity and distribution in this climate-vulnerable ocean ecosystem.

    To facilitate preparing Biological Assessments of proposed channel maintenance projects, the Portland District of the U.S. Army Corps of Engineers contracted the Pacific Northwest National Laboratory to consolidate and synthesize available information about the use of the lower Columbia River and estuary by juvenile anadromous salmonids. The information to be synthesized included existing published documents as well as data from five years (2004-2008) of acoustic telemetry studies conducted in the Columbia River estuary using the Juvenile Salmon Acoustic Telemetry System. For this synthesis, the Columbia River estuary includes the section of the Columbia River from Bonneville Dam at river kilometer (Rkm) 235 downstream to the mouth where it enters the Pacific Ocean. In this report, we summarize the seasonal salmonid presence and migration patterns in the Columbia River estuary based on information from published studies as well as relevant data from acoustic telemetry studies conducted by NOAA Fisheries and the Pacific Northwest National Laboratory (PNNL) between 2004 and 2008. Recent acoustic telemetry studies, conducted using the Juvenile Salmon Acoustic Telemetry System (JSATS; developed by the Portland District of the U.S. Army Corps of Engineers), provided information on the migratory behavior of juvenile steelhead (O. mykiss) and Chinook salmon in the Columbia River from Bonneville Dam to the Pacific Ocean. In this report, Section 2 provides a summary of information from published literature on the seasonal presence and migratory behavior of juvenile salmonids in the Columbia River estuary and plume. Section 3 presents a detailed synthesis of juvenile Chinook salmon and steelhead migratory behavior based on use of the JSATS between 2004 and 2008. Section 4 provides a discussion of the information summarized in the report as well as information drawn from literature reviews on potential effects of channel maintenance activities to juvenile salmonids rearing in

    Semiarid forests are very sensitive to climatic change and among the most difficult ecosystems to accurately model. We tested the performance of the Biome-BGC model against eddy flux data taken from young (years 2004-2008), mature (years 2002-2008), and old-growth (year 2000) ponderosa pine stands at Metolius, Oregon, and subsequently examined several potential causes for model-data mismatch. We used the Generalized Likelihood Uncertainty Estimation methodology, which involved 500,000 model runs for each stand (1,500,000 total). Each simulation was run with randomly generated parameter values from a uniform distribution based on published parameter ranges, resulting in modeled estimates of net ecosystem CO2 exchange (NEE) that were compared to measured eddy flux data. Simulations for the young stand exhibited the highest level of performance, though they overestimated ecosystem C accumulation (-NEE) 99% of the time. Among the simulations for the mature and old-growth stands, 100% and 99% of the simulations underestimated ecosystem C accumulation. One obvious area of model-data mismatch is soil moisture, which was overestimated by the model in the young and old-growth stands yet underestimated in the mature stand. However, modeled estimates of soil water content and associated water deficits did not appear to be the primary cause of model-data mismatch; our analysis indicated that gross primary production can be accurately modeled even if soil moisture content is not. Instead, difficulties in adequately modeling ecosystem respiration, mainly autotrophic respiration, appeared to be the fundamental cause of model-data mismatch.

    Full Text Available Within the CRENODAT project (Biodiversity assessment and integrity evaluation of springs of Trentino - Italian Alps - and longterm ecological research, 2004-2008 we studied a total of 90 springs in Trentino (south-eastern Alps, Italy, 75 of which were used for statistical analysis. The springs were grouped into seven different types and represented all the available lithologies in the study area. Macrozoobenthos (Ephemeroptera, Plecoptera and Trichoptera; EPT was collected from stones, bryophytes and sediments. We investigated which physical, chemical or environmental features were important in determining EPT assemblage metrics at sites, by calculating the Shannon-Wiener diversity index, and applying a one-way ANOVA test, ANOSIM and SIMPER analyses. Statistical results highlighted the island character of the springs, each spring having its specific history and abiotic characteristics, which select for unique community patterns. For the faunistic analyses, we considered all springs where EPT taxa were recorded; a total of 88 taxa. Highest species richness was recorded among the Trichoptera, followed by the Plecoptera and Ephemeroptera, with 52, 30 and 6 taxa respectively. Fifteen Trichoptera and three Plecoptera species were recorded as new for the Autonomous Province of Trento. Our results confirm that, in the harsh environment of the Alps, the mild and stable ecological conditions that characterize spring-fed brooks contribute to maintaining and enhancing the regional biodiversity. Springs act as refuge areas for stream biota, providing more favourable conditions during spates or droughts (common in Alpine headwaters, or for particular stages of the insect life cycles. Springs also provide specific habitats for strictly crenobiontic species.

    The testing of products of wheat cereal (310 samples), vegetable (418 samples), confectionery (439 samples) and 952 samples of products for infants and children has initiated the 5-years cycle of monitoring investigations on food contamination with elements noxious to human health planned to perform in 2004-2008. The parties involved in testing were: laboratories of State Sanitary Inspection collecting samples on all over the territory of Poland, both from retail market (of domestic origin as well as imported) and directly from producers; the national reference laboratory of the Department of Food and Consumer Articles Research of National Institute of Public Health - National Institute of Hygiene responsible for elaboration of official food control and monitoring plans to be approved by Chief Sanitary Inspectorate and for the substantive supervising of tests performance. The reported metals contents were not of health concern and generally below the levels set forth in food legislation. The health hazard assessment was performed taking into account the mean contamination obtained and average domestic consumption of these food products groups in Poland. The highest intake expressed as the percentage of provisional tolerable weekly intake (PTWI) was obtained for cadmium, which has reached 9.4% PTWI for cereal based products and 4.7% PTWI for vegetables. The cadmium content in chocolate and derived products due to contamination of cocoa beans and the levels of this element in products for infants and children originated from contamination of cereal and soybeans row materials should not be ignored. The decrease of lead contamination comparing to those reported in 1990 studies was observed.

    The entry of the Cassini-Huygens spacecraft into orbit around Saturn in July 2004 marked the start of a golden era in the exploration of Titan, Saturn's giant moon. During the Prime Mission (2004-2008), ground-breaking discoveries were made by the Cassini orbiter including the equatorial dune fields (flyby T3, 2005), northern lakes and seas (T16, 2006), and the large positive and negative ions (T16 & T18, 2006), to name a few. In 2005 the Huygens probe descended through Titan's atmosphere, taking the first close-up pictures of the surface, including large networks of dendritic channels leading to a dried-up seabed, and also obtaining detailed profiles of temperature and gas composition during the atmospheric descent. The discoveries continued through the Equinox Mission (2008-2010) and Solstice Mission (2010-2017) totaling 127 targeted flybys of Titan in all. Now at the end of the mission, we are able to look back on the high-level scientific questions from the start of the mission, and assess the progress that has been made towards answering these. At the same time, new scientific questions regarding Titan have emerged from the discoveries that have been made. In this paper we review a cross-section of important scientific questions that remain partially or completely unanswered, ranging from Titan's deep interior to the exosphere. Our intention is to help formulate the science goals for the next generation of planetary missions to Titan, and to stimulate new experimental, observational and theoretical investigations in the interim.

  12. Gefinex 400S (SAMPO) EM-soundings at Olkiluoto 2009

    2009-09-01

    In the beginning of June 2009 Geological Survey of Finland (GTK) carried out electromagnetic (EM) frequency soundings with Gefinex 400S equipment (Sampo) in the vicinity of ONKALO at the Olkiluoto site investigation area. The EM-monitoring sounding program started in 2004 and has been repeated since yearly in the same season. The aim of the study is to monitor the variations of the groundwater properties down to 500 m depth by the changes of the electric conductivity of the earth at ONKALO and repository area. The original measurement grid was based on two 1400 m long broadside profiles, which have 200 m mutual distance and 200 m station separation. The receiver and transmitter sites are marked with stakes and the profiles were measured using 200, 500, and 800 m coil separations. The measurement program was revised in 2007 and then again in 2009. Now 15 noisy soundings were removed from the program and 3 new points were selected from the area to the east from ONKALO. The new receiver/transmitter sites, called ABC-points were marked with stakes and the points were measured using transmitter-receiver separations 200, 400 and 800 meters. In 2009 the new EM-Sampo monitoring program included 28+9 soundings. The numerous power lines and cables in the area generate local disturbances on the sounding curves, but the SN (signal to noise) ratio and the repeatability of the results is reasonably good even with long coil separations. However, most suitable for monitoring purposes are the sites without strong shallow 3D effects. Comparison of the new results to old 2004-2008 surveys shows differences on some ARD (apparent resistivity-depth) curves. Those are mainly results of the modified shallow structures. The changes in groundwater conditions based on the monitoring results seem insignificant. (orig.)

    The seventh cholera pandemic caused by Vibrio cholerae O1 El Tor (ET) has been superseded in Asia and Africa by altered ET possessing the cholera toxin (CTX) gene of classical (CL) biotype. The CL biotype of V. cholerae was isolated, along with prototypic and altered ET, during the 1991 cholera epidemic in Mexico and subsequently remained endemic until 1997. Microbiological, molecular, and phylogenetic analyses of clinical and environmental V. cholerae isolated in Mexico between 1998 and 2008 revealed important genetic events favoring predominance of ET over CL and altered ET. V. cholerae altered ET was predominant after 1991 but not after 2000. V. cholerae strains isolated between 2001 and 2003 and a majority isolated in 2004 lacked CTX prophage (Φ) genes encoding CTX subunits A and B and repeat sequence transcriptional regulators of ET and CL biotypes: i.e., CTXΦ(-). Most CTXΦ(-) V. cholerae isolated in Mexico between 2001 and 2003 also lacked toxin coregulated pili tcpA whereas some carried either tcpA(ET) or a variant tcpA with noticeable sequence dissimilarity from tcpA(CL). The tcpA variants were not detected in 2005 after CTXΦ(+) ET became dominant. All clinical and environmental V. cholerae O1 strains isolated during 2005-2008 in Mexico were CTXΦ(+) ET, carrying an additional truncated CTXΦ instead of RS1 satellite phage. Despite V. cholerae CTXΦ(-) ET exhibiting heterogeneity in pulsed-field gel electrophoresis patterns, CTXΦ(+) ET isolated during 2004-2008 displayed homogeneity and clonal relationship with V. cholerae ET N16961 and V. cholerae ET isolated in Peru.

  14. Do flexible alcohol trading hours reduce violence? A theory-based natural experiment in alcohol policy.

    Science.gov (United States)

    Humphreys, David K; Eisner, Manuel P

    2014-02-01

    Alcohol-related violence is a pressing public health concern. In 2005, the government of England and Wales took a controversial approach to preventing violence by removing restrictions on opening hours for alcohol outlets, thus increasing the availability of alcohol. The policy aimed to remove fixed closing times, which it claimed was contributing to urban violence occurring at peak closing times. It proposed to reduce violence and disorder by installing systems of 'staggered closing times'. This policy was criticised for overlooking established public health principles prioritising the control of alcohol availability in the prevention of alcohol-related harm. In this study, we treated the removal of trading hour restrictions as a natural experiment to test competing theoretical principles about the relationship between alcohol availability and violence. Our study took place in the City of Manchester over a four-year period 2004-2008. Detailed trading records for over 600 alcohol outlets were obtained, as were police records for all violent incidents. We found considerable variation in the implementation of extended trading hours across the city, which affected area-level exposure of changes in alcohol availability and staggered closing times. To isolate the effect of these changes on violence, we performed a dose-response analysis to examine whether improved staggering of closing hours (or increased alcohol availability) was associated with decreases in violence. We found no evidence to support the government-proposed hypothesis that staggered closing reduces violence. We also found no support for the alternative hypothesis; that increase alcohol availability would result in increased violence. This study provides an example of how better evidence can be generated from natural experiments by placing added emphasis on theory, causal mechanisms and implementation science.

    2014-03-01

    A wide variety of atomic, molecular, radiative and plasma-wall interaction processes involving a mixture of atoms, ions and molecules occur in the plasmas produced in nuclear fusion experiments. In the low temperature divertor and near wall region, molecules and molecular ions are formed. The plasma particles react with electrons and with each other. Plasma modelling requires cross-sections and rate coefficients for all these processes, and in addition spectral signatures to support interpretation of data from fusion experiments. The mission of the International Atomic Energy Agency Nuclear Data Section (IAEA/NDS) in the area of atomic and molecular data is to enhance the competencies of Member States in their research into nuclear fusion through the provision of internationally recommended atomic, molecular, plasma-material interaction and material properties databases. One mechanism by which the IAEA pursues this mission is the Coordinated Research Project (CRP). The present volume of Atomic and Plasma-Material Interaction Data for Fusion contains contributions from participants in the CRP 'Atomic and Molecular Data for Plasma Modelling' (2004-2008). This CRP was concerned with data for processes in the near wall and divertor plasma and plasma-wall interaction in fusion experiments, with focus on cross-sections for molecular reactions. Participants in the CRP came from 14 different institutes, many with strong ties to fusion plasma modelling and experiment. D. Humbert of the Nuclear Data Section was scientific secretary of the CRP. Participants' contributions for this volume were collected and refereed after the conclusion of the CRP

    To investigate the difference between nurses and the general population regarding seasonal variations in sleep disorders during 2004-2008. The effects of season and group interaction on sleep disorders with regard to different comorbidities were also examined. Studies on seasonal variations in sleep disorders were mainly conducted in Norway for the general population. Furthermore, whether different comorbidities cause seasonal variations in sleep disorders in nurses remains unknown. A retrospective study. Data from the Taiwan National Health Insurance Research Database were used in generalised estimating equation Poisson distribution models to investigate the differences in sleep disorders between nurses and the general population diagnosed with sleep disorders (each n = 7643) as well as the interaction effects of sleep disorders between the groups with respect to different seasons. Furthermore, the interaction effects between groups and seasons on sleep disorders in the subgroups of comorbid anxiety disorders and depressive disorders were studied. Both the nurses and the general population had fewer outpatient visits for sleep disorders in winter than in other seasons. The nurses had fewer outpatient visits for sleep disorders than the general population did in each season. The nurses had more outpatient visits for sleep disorders in winter than in summer compared with the general population in the comorbid depressive disorder subgroup but not in the comorbid anxiety disorder subgroup. Nurses and the general population exhibited similar seasonal patterns of sleep disorders, but nurses had fewer outpatient visits for sleep disorders than the general population did in each season. For nurses with comorbid depressive disorders, outpatient visits for sleep disorders were more numerous in winter than in summer, potentially because nurses with comorbid depressive disorders are affected by shorter daylight exposure during winter. Depression and daylight exposure may

    To improve the fuel cycle economics and to further increase the VVER fuel usability the work programme is under way to design novel improved fuel, fuel rods and fuel assemblies. Longer FA operation time that is needed to increase the fuel burnup and the related design developments of novel fuel assemblies resulted not only in changing types and sizes of Zirconium items and fuel assembly components but also altered the requirements placed on their technical characteristics. To use fuel rods having a larger charge of fuel, to improve their behaviour in LOCA, to reduce fuel rod damage ability during assembling the work was carried out to perfect the characteristics of both the cladding (reduced wall thickness and more rigid tolerances for geometry) and its material. To meet the more rigid requirements for the geometry dimensions of cladding tubes an improved process flow sheet has been designed and employed for their fabrication and also the finishing treatment of tube surfaces has been improved. The higher and stable properties of the cladding materials were managed through using the special purity in terms of Hafnium Zirconium (not higher than 100 ppm Hf) as a base of the E110 alloy and maintaining within the valid specifications for the alloy the optimized contents of Oxygen and Iron at the levels of (600 - 990) ppm and (250 - 700) ppm, respectively. The work was under way in 2004 - 2008 years; during this period the technology and materials science solutions were mastered that were phased-in introduced into the production of the cladding tubes for the fuels loaded into the of the Kalinin NPP Unit 1

    Full Text Available Resumo Este artigo analisa a trajetória dos prefeitos das 26 capitais estaduais brasileiras eleitos no período 1996-2008 após chegarem ao cargo. Busca identificar se procuraram novos postos eletivos e, em caso positivo, quais foram eles e os resultados alcançados, de modo a verificar a presença de algum padrão predominante nessas decisões com vistas a dar continuidade à carreira. O universo da pesquisa é formado por 77 indivíduos, quatro disputas de âmbito municipal (2000, 2004, 2008 e 2012 e outras cinco de âmbitos estadual e nacional (1998, 2002, 2006, 2010 e 2014, tendo o TSE como fonte principal. O fato de tais atores ocuparem o cargo de chefe do Executivo de um município com grande visibilidade e importância política e econômica no seu respectivo estado foi o ponto de partida do artigo, pois tais condições abrem a perspectiva de que possam alcançar outros postos eletivos relevantes na hierarquia política. Ao considerar as situações específicas desses prefeitos (reeleitos, desistentes da reeleição, derrotados e renunciantes em meio ao mandato, os resultados apontam que a ampla maioria pretende continuar na carreira política, inicialmente ao renovar o mandato e, na sequência, buscar outro posto eletivo, com preferência aos cargos legislativos. A taxa de sucesso na busca da reeleição é elevada, mas, ao ambicionar um cargo distinto, preponderam as derrotas, sendo que o posto mais seguro a ser alcançado é o de deputado federal.

  20. Exploring Pacific Climate Variability and Its Impacts on East African Water Resources and Food Security

    In 8 out the past 15 boreal springs (1999, 2000, 2004, 2008, 2009, 2011, 2012, and 2013), substantial parts of eastern East Africa experienced very low boreal spring rains. These rainfall deficits have triggered widespread food insecurity, and even contributed to the outbreak of famine conditions in Somalia in 2011. At both seasonal and decadal time scales, new science supported by the USAID Famine Early Warning Systems Network seeks to understand the mechanisms producing these droughts. We present research suggesting that the ultimate and proximate causes of these increases in aridity are i) stronger equatorial Pacific SST gradients and ii) associated increases in the strength of the Indo-Pacific Walker circulation. Using observations and new modeling ensembles, we explore the relative contributions of Pacific Decadal Variability (PDV) and global warming under warm and cold east Pacific Ocean states. This question is addressed in two ways: by using atmospheric GCMs forced with full and ENSO-only SSTs, and ii) by decomposing coupled ocean-atmosphere climate simulations into PDV and non-PDV components. These analyses allow us to explore the Walker circulation's sensitivity to climate change under various PDV states, and inform a tentative bracketing of 2030 climate conditions. We conclude by discussing links to East African development. Regions of high rainfall sensitivity are delineated and intersected with recent changes in population and land cover/land use. The interaction of elevation and climate is shown to create climatically secure regions that are likely to remain viable even under drier and warmer conditions; such regions may be logical targets for agricultural intensification. Conversely, arid low elevation regions are likely to experience substantial temperature impacts. Continued expansion into these areas may effectively create more 'drought' even if rainfall increases.

  1. Final Progress Report: Collaborative Research: Decadal-to-Centennial Climate & Climate Change Studies with Enhanced Variable and Uniform Resolution GCMs Using Advanced Numerical Techniques

    The joint U.S-Canadian project has been devoted to: (a) decadal climate studies using developed state-of-the-art GCMs (General Circulation Models) with enhanced variable and uniform resolution; (b) development and implementation of advanced numerical techniques; (c) research in parallel computing and associated numerical methods; (d) atmospheric chemistry experiments related to climate issues; (e) validation of regional climate modeling strategies for nested- and stretched-grid models. The variable-resolution stretched-grid (SG) GCMs produce accurate and cost-efficient regional climate simulations with mesoscale resolution. The advantage of the stretched grid approach is that it allows us to preserve the high quality of both global and regional circulations while providing consistent interactions between global and regional scales and phenomena. The major accomplishment for the project has been the successful international SGMIP-1 and SGMIP-2 (Stretched-Grid Model Intercomparison Project, phase-1 and phase-2) based on this research developments and activities. The SGMIP provides unique high-resolution regional and global multi-model ensembles beneficial for regional climate modeling and broader modeling community. The U.S SGMIP simulations have been produced using SciDAC ORNL supercomputers. Collaborations with other international participants M. Deque (Meteo-France) and J. McGregor (CSIRO, Australia) and their centers and groups have been beneficial for the strong joint effort, especially for the SGMIP activities. The WMO/WCRP/WGNE endorsed the SGMIP activities in 2004-2008. This project reflects a trend in the modeling and broader communities to move towards regional and sub-regional assessments and applications important for the U.S. and Canadian public, business and policy decision makers, as well as for international collaborations on regional, and especially climate related issues.

    Measurements of mesospheric carbon monoxide, CO, provide important information about the dynamics in the mesosphere region since CO has a long lifetime at these altitudes. Ground-based measurements of mesospheric CO made at the Onsala Space Observatory, OSO, (57° N, 12° E) are presented. The dataset covers the period 2002-2008 and is hence uniquely long for ground-based observations. The simple and stable 115 GHz frequency-switched radiometer, calibration method, retrieval procedure and error characterization are described. A comparison between our measurements and co-located CO measurements from the satellite sensors ACE-FTS on Scisat (v2.2), MLS on Aura (v3-3), MIPAS on Envisat (V3O_CO_12 + 13 and V4O_CO_200) and SMR on Odin (v225 and v021) is carried out. Our instrument, OSO, and the four satellite instruments show the same general variation of the vertical distribution of mesospheric CO in both the annual cycle and in shorter time period events, with high CO mixing ratios during winter and very low amounts during summer in the observed 55-100 km altitude range. During 2004-2008 the agreement of the OSO instrument and the satellite sensors ACE-FTS, MLS and MIPAS (200) is good in the altitude range 55-70 km. Above 70 km, OSO shows up to 25% higher CO column values compared to both ACE and MLS. For the time period 2002-2004, CO from MIPAS (12 + 13) is up to 50% lower than OSO between 55 and 70 km. Mesospheric CO from the two versions of SMR deviates up to ±65% when compared to OSO, but the analysis is based on only a few co-locations.

    Fish contain nutrients essential to the developing fetal brain, but they are contaminated with methylmercury. The Tohoku Study of Child Development, now underway in the Sanriku coastal area of Miyagi prefecture, Japan, follows mother-child pairs to examine the risks and benefits of fish consumption during pregnancy, especially the effects of prenatal exposures to methylmercury, selenium, and docosahexaenoic acid (DHA) on child neurodevelopment. Children aged 18 months were administered the Bayley Scales of Infant Development second edition (BSID-II) and Kyoto Scale of Psychological Development (KSPD) in 2004-2008. Complete data of cord-blood total mercury (THg), cord-plasma selenium, maternal-plasma DHA, the above test scores, and confounders for 566 mother-child pairs were available. The median cord-blood THg level was 15.7 (range, 2.7-96.1) ng/g. Since the BSID-II and KSPD scores were significantly lower in the 285 boys than in the 281 girls, analyses were conducted separately. The Psychomotor Development Index (PDI) of BSID-II was significantly correlated with cord-blood THg only in the boys, and significance of the association remained unchanged after adjusting for possible confounders; i.e., a 10-fold increase in cord-blood THg was associated with a 8.3-point decrease in the score of the PDI. Other significant correlations of THg were not seen in the boys or girls. Selenium and DHA showed no significant correlations with the BSID-II or KSPD scores in either sex. In conclusion, intrauterine methylmercury exposure may affect psychomotor development, and boys appear to be more vulnerable to the exposure than girls.

    Full Text Available Double expression of MYC and BCL2 proteins (DE and double-hit MYC+BCL2/BCL6 translocations (DH were established as important biomarkers in patients with diffuse large B-cell lymphoma (DLBCL by the 2016 revision of the World Health Organization classification of lymphoid neoplasms. Whether this applies to the subgroup of young patients with high risk DLBCL is not known. We previously found that in a uniform retrospective population-based cohort of patients aged 18-60 years with high-risk DLBCL, the addition of etoposide to R-CHOP chemotherapy (R-CHOEP resulted in improved survival mainly in patients with germinal center B-cell like (GCB immunophenotype. The aim of this study was to investigate the prognostic and predictive value of DE and DH in this patient cohort.Data on all young Danish patients diagnosed with de novo high-risk DLBCL 2004-2008 and treated with R-CHOP or R-CHOEP were obtained from the Danish Lymphoma database (n = 159.

MYC-, BCL2- and BCL6-translocations were examined with fluorescent in situ hybridization (FISH.DE with MYC>75% and BCL2>85% was an independent negative prognostic marker of progression free survival (PFS in patients treated with R-CHOP but not R-CHOEP (p<0.001, also after exclusion of patients with DH. A predictive effect of DE for response (PFS to R-CHOEP vs. R-CHOP was almost significant (p = 0.07. DH was not prognostic in this patient cohort.In young patients with high-risk DLBCL, treatment with R-CHOEP may overcome the negative prognostic impact of DE observed in patients treated with R-CHOP.

    Locally abundant feral horses (Equus caballus) can rapidly deplete available resources. Fertility control agents present promising nonlethal tools for reducing their population growth rates. We tested the effect of 2 forms of the immunocontraceptive porcine zona pellucida (PZP) on foaling rates in 3 populations of feral horses in the western United States. A liquid form requiring annual boosters was administered at Little Book Cliffs Wild Horse Range, Mesa County (CO), and Pryor Mountain Wild Horse Range, Bighorn County (WY) and Carbon County (MT), and a time-release pellet form designed to produce 2 yr of infertility was administered at McCullough Peaks Herd Management Area, Park County (WY). Average foaling rates (foals born/mare-yr) from direct observation of untreated and treated female horses (mares), 2004-2008, were 60.1% (n = 153 mare-yr) versus 6.6% (n = 91 mare-yr) at Little Book Cliffs, and 62.8% (n = 129 mare-yr) versus 17.7% (n = 79 mare-yr) at Pryor Mountain, respectively. At McCullough Peaks, mean annual foaling rates from 2006 to 2008 were 75.0% (n = 48 mare-yr) for untreated mares and 31.7% (n = 101 mare-yr) for treated mares. Controlling for age of mares and pretreatment differences in fertility, PZP reduced foaling rates in all 3 herds. The pellets used at McCullough Peaks (produced by cold evaporation) were less effective than pellets used in a previous trial and produced by heat extrusion. Immunocontraception with PZP may be a useful tool in reducing fertility rates in some western United States feral horse herds, but population growth reduction will depend on timely access to mares for inoculation and the proportion of mares that can be successfully treated. ?? 2011 The Wildlife Society.

    Increasing numbers of individuals are choosing to opt out of population-based sampling frames due to privacy concerns. This is especially a problem in the selection of controls for case-control studies, as the cases often arise from relatively complete population-based registries, whereas control selection requires a sampling frame. If opt out is also related to risk factors, bias can arise. We linked breast cancer cases who reported having a valid driver's license from the 2004-2008 Wisconsin women's health study (N = 2,988) with a master list of licensed drivers from the Wisconsin Department of Transportation (WDOT). This master list excludes Wisconsin drivers that requested their information not be sold by the state. Multivariate-adjusted selection probability ratios (SPR) were calculated to estimate potential bias when using this driver's license sampling frame to select controls. A total of 962 cases (32%) had opted out of the WDOT sampling frame. Cases age <40 (SPR = 0.90), income either unreported (SPR = 0.89) or greater than $50,000 (SPR = 0.94), lower parity (SPR = 0.96 per one-child decrease), and hormone use (SPR = 0.93) were significantly less likely to be covered by the WDOT sampling frame (α = 0.05 level). Our results indicate the potential for selection bias due to differential opt out between various demographic and behavioral subgroups of controls. As selection bias may differ by exposure and study base, the assessment of potential bias needs to be ongoing. SPRs can be used to predict the direction of bias when cases and controls stem from different sampling frames in population-based case-control studies.

  8. Mechanisms of time-based figure-ground segregation.

    Kandil, Farid I; Fahle, Manfred

    2003-11-01

    Figure-ground segregation can rely on purely temporal information, that is, on short temporal delays between positional changes of elements in figure and ground (Kandil, F.I. & Fahle, M. (2001) Eur. J. Neurosci., 13, 2004-2008). Here, we investigate the underlying mechanisms by measuring temporal segregation thresholds for various kinds of motion cues. Segregation can rely on monocular first-order motion (based on luminance modulation) and second-order motion cues (contrast modulation) with a high temporal resolution of approximately 20 ms. The mechanism can also use isoluminant motion with a reduced temporal resolution of 60 ms. Figure-ground segregation can be achieved even at presentation frequencies too high for human subjects to inspect successive frames individually. In contrast, when stimuli are presented dichoptically, i.e. separately to both eyes, subjects are unable to perceive any segregation, irrespective of temporal frequency. We propose that segregation in these displays is detected by a mechanism consisting of at least two stages. On the first level, standard motion or flicker detectors signal local positional changes (flips). On the second level, a segregation mechanism combines the local activities of the low-level detectors with high temporal precision. Our findings suggest that the segregation mechanism can rely on monocular detectors but not on binocular mechanisms. Moreover, the results oppose the idea that segregation in these displays is achieved by motion detectors of a higher order (motion-from-motion), but favour mechanisms sensitive to short temporal delays even without activation of higher-order motion detectors.

    2017-12-01

    The floods event in the north of Java was largely due to persistent of rainfall that occurred in the morning which indicated of deviation of diurnal pattern of rainfall. The shift of the phase of diurnal rainfall cycle using TRMM satellite hourly data of 3B41RT on the rainy period of 2000-2016 exhibits over land from Late Afternoon-Early Midnight (LA-EM) to morning. The peak of the cycle changes from diurnal to semidiurnal with a peak occurring in LA-EM and morning. Location of rainfall which usually occurs in the oceans shifted into near coastal area. The classification of diurnal rainfall cycles based on composite analysis shows four types: Normal (N) Type (45.6%) with one peak rainfall occurring in the afternoon until night, Diurnal (D) Type (26%) with one peak and phase opposite to normal type, Semidiurnal (SD) Type (6.5 %) with two peaks and the main peak occurring in the afternoon until night, Third Diurnal (TD) Type (21.7%) with three peaks and the main peak occurs in the morning. The classification was confirmed using the objective method of Empirical Mode Decomposition (EMD) and obtained three IMFs representing three diurnal cycle modes of Type TD (67.8%) with the main rain peak taking place in the afternoon, Type D with rain peak occurring in the early hours (18.9%), and SD type (9.9%) with the first peak occurred in the afternoon. For D Type, the results also prove that the diurnal cycle with significant deviations in amplitude occurred in February 2002, 2004, 2008, 2014, wich is the maximum rainfall occurs in the EM. It also seems that in those years, rainfall intensity is concentrated on the northern coast of West Java while in the Java Sea rainfall was minimum.

    To determine if a sentinel lymph node (SLN) mapping algorithm will detect metastatic nodal disease in patients with intermediate-/high-risk endometrial carcinoma. Patients were identified and surgically staged at two collaborating institutions. The historical cohort (2004-2008) at one institution included patients undergoing complete pelvic and paraaortic lymphadenectomy to the renal veins (LND cohort). At the second institution an SLN mapping algorithm, including pathologic ultra-staging, was performed (2006-2013) (SLN cohort). Intermediate-risk was defined as endometrioid histology (any grade), ≥50% myometrial invasion; high-risk as serous or clear cell histology (any myometrial invasion). Patients with gross peritoneal disease were excluded. Isolated tumor cells, micro-metastases, and macro-metastases were considered node-positive. We identified 210 patients in the LND cohort, 202 in the SLN cohort. Nodal assessment was performed for most patients. In the intermediate-risk group, stage IIIC disease was diagnosed in 30/107 (28.0%) (LND), 29/82 (35.4%) (SLN) (P=0.28). In the high-risk group, stage IIIC disease was diagnosed in 20/103 (19.4%) (LND), 26 (21.7%) (SLN) (P=0.68). Paraaortic lymph node (LN) assessment was performed significantly more often in intermediate-/high-risk groups in the LND cohort (P<0.001). In the intermediate-risk group, paraaortic LN metastases were detected in 20/96 (20.8%) (LND) vs. 3/28 (10.7%) (SLN) (P=0.23). In the high-risk group, paraaortic LN metastases were detected in 13/82 (15.9%) (LND) and 10/56 (17.9%) (SLN) (%, P=0.76). SLN mapping algorithm provides similar detection rates of stage IIIC endometrial cancer. The SLN algorithm does not compromise overall detection compared to standard LND.

    Full Text Available El volumen de la copa bien iluminada es uno de los factores clave en la productividad de árboles de nogal pecanero. Cuando las huertas de nogal pecanero con densidades de plantación al menos de 100 árboles por hectárea presentan problemas de sombreo, la penetración de luz dentro de la copa del árbol y entre árboles, el crecimiento y la producción son negativamente afectadas. La investigación realizada para estudiar el efecto del aclareo de árboles de nogal pecanero sobre la disponibilidad de la luz y productividad de la huerta es limitada. El objetivo del presente estudio fue determinar el efecto del aclareo de árboles sobre la disponibilidad de radiación fotosintéticamente activa (RFA dentro de árboles permanentes, crecimiento del brote, producción y calidad de la nuez. Este estudio se llevó a cabo en una huerta madura de nogal pecanero con aclareo de árboles de 25 a 50 % durante el periodo 2004-2008. La disponibilidad de RFA dentro de árboles, longitud de brotes y la producción de nuez fueron afectadas por los tratamientos de aclareo; sin embargo, la calidad (porcentaje de almendra por árbol durante el periodo de tres años de estudio no fue significativamente afectada. Los resultados de este estudio indican que un gradual aclareo en huertas con problemas de sombreo debe realizarse para recuperar el crecimiento y componentes de producción.

    Based on the remote sensing data and with the help of geographic information system, an integrated assessment was conducted on the eco-environmental vulnerability of Pearl River Delta in 2004-2008. Spatial principal component analysis was used to generate the evaluation indicators, and analytic hierarchy process (AHP) was applied to determine the weights of the evaluation factors. The reasons causing the vulnerability of the eco- environment in Pearl River Delta were discussed. In the study area, its middle part was the most vulnerable region, occupying 34.0% of the total, eastern part was the moderately vulnerable region, accounting for 25.5%, and western part was the lightly and slightly vulnerable areas, accounting for 28.7 and 11.8%, respectively. Totally, the moderately and lightly vulnerable areas occupied 54.2%, indicating that a majority of the Delta was under moderate and light vulnerability. The natural factors affecting the eco-environmental vulnerability of the Delta were altitude, heavy rain days, water and soil erosion rate, flooded infield rate, normalized difference vegetation index (ND VI) and landscape diversity index, whereas the human factors were population density, waste discharge per unit area, exhaust emission per unit area, land use change, chemical fertilization intensity, pesticide application intensity, amount of motor vehicles possessed by ten thousands people, and index of environmental protection investment. The main characteristics of the extremely and heavily vulnerable regions were low altitude, high frequency of flood disaster, large flooded infield, serious vegetation degradation, high pollution level and low environment protection investment index.

Flight diversions due to medical emergencies carry a significant financial and legal cost. The purpose of this study was to determine the causes of in-flight medical diversions from Air Canada. This was a review of in-flight medical emergencies from 2004-2008. Both telemedicine and Air Canada databases were crossreferenced to capture all incidents. Presenting complaints were categorized by systems. Descriptive statistics were used to analyze the data. Over the 5 yr, there were 220 diversions, of which 91 (41.4%) of the decisions were made by pilots or onboard medical personnel. During this period there were 5386 telemedicine contacts with ground support providers, who on average recommended 2.4 diversions per 100 calls. The rate for diversions almost doubled from 2006 to 2007, with a sharp drop in telemedicine contacts during the same period. The four most common categories resulting in diversions were cardiac (58 diversions, 26.4%), neurological (43 diversions, 19.5%), gastrointestinal (GI) (25 diversions, 11.4%), and syncope (22 diversions, 10.0%). Only 6.8% of all diversions were due to cardiac arrest. Medical conditions most commonly leading to diversions were cardiac, neurological, gastrointestinal, and syncope. Our study showed that a decrease in telemedicine contact during this period was accompanied by an increase in diversions, while increased pre-screening of passengers did not prove effective in decreasing diversion rates.

    Definition of a Krsko Periodic Safety Review (PSR) project is a comprehensive safety review of a plant after last ten years of operation. The objective is a verification by means of a comprehensive review using current methods that Krsko NPP remains safety when judged against current safety objectives and practices and that adequate arrangements are in place to maintain plant safety. This objective encompasses the three main criteria or goals: confirmation that the plant is as safe as originally intended, determination if there are any structures, systems or components that could limit the life of the plant in the foreseeable future, and comparison the plant against modern safety standards and to identify where improvements would be beneficial at justifiable cost. Krsko PSR project is structured in the three phases: Phase 1: Preparation of Detailed 10-years PSR Program, Phase 2: Performing of 10-years PSR Program and preparing of associated documents (2001-2003), and Phase 3: Implementation of the prioritized compensatory measures and modifications (development of associated EEAR, DMP, etc.) after agreement with the SNSA on the design, procedures and time-scales (2004-2008). This paper presents the NEK PSR results of work performed under Phase 2 focused on the ranking of safety issues and prioritization of corrective measures needed for establishing an efficient action plan. Safety issues were identified in Phase 2 during the following review processes: Periodic Safety Review (PSR) task; Krsko NPP Regulatory Compliance Program (RCP) review; Westinghouse Owner Group (WOG) catalog items screening/review; SNSA recommendations (including IAEA RAMP mission suggestions/recommendations).(author)

    Childhood adversities are strong predictors of psychopathology and suicidality. However, specific adversities are associated with different outcomes, with cross-national variations reported. The current study examined rates of adversities reported in Northern Ireland (NI), and associations between adverse childhood experiences and psychopathology and suicidal behaviour were explored. Data was obtained from the Northern Ireland Study of Health and Stress (NISHS), conducted as part of the World Mental Health (WMH) survey initiative (2004-2008); response rate 68.4% (n = 1,986). The on-line survey used, the WHO Composite International Diagnostic Interview (CIDI) to examine psychopathology and associated risk factors in the NI population. Prevalence rates of retrospectively reported childhood adversities were calculated, with gender and age variations explored. Females were more likely to experience sexual abuse. Individuals who grew up during the worst years of the civil conflict in NI experienced elevated levels of childhood adversities. Participants who endured childhood adversities were more likely to have mental health problems but variations in risk factors were found for different disorders. Parental mental illness was associated with all disorders however, with ORs ranging from 2.20 for mood disorders to 4.07 for anxiety disorders. Population attributable fractions (PAF) estimated the reduction in psychopathology and suicidal behaviour in the population if exposure to adverse childhood events had not occurred. The highest PAF values were revealed for parental mental illness and sexual abuse. The findings indicate that a substantial proportion of psychopathology and suicide risk in NI are attributable to childhood adversities, providing support for early intervention and prevention initiatives.

    Full Text Available BACKGROUND: Migrations allow animals to find food resources, rearing habitats, or mates, but often impose considerable predation risk. Several behavioural strategies may reduce this risk, including faster travel speed and taking routes with shorter total distance. Descriptions of the natural range of variation in migration strategies among individuals and populations is necessary before the ecological consequences of such variation can be established. METHODOLOGY/PRINCIPAL FINDINGS: Movements of tagged juvenile coho, steelhead, sockeye, and Chinook salmon were quantified using a large-scale acoustic tracking array in southern British Columbia, Canada. Smolts from 13 watersheds (49 watershed/species/year combinations were tagged between 2004-2008 and combined into a mixed-effects model analysis of travel speed. During the downstream migration, steelhead were slower on average than other species, possibly related to freshwater residualization. During the migration through the Strait of Georgia, coho were slower than steelhead and sockeye, likely related to some degree of inshore summer residency. Hatchery-reared smolts were slower than wild smolts during the downstream migration, but after ocean entry, average speeds were similar. In small rivers, downstream travel speed increased with body length, but in the larger Fraser River and during the coastal migration, average speed was independent of body length. Smolts leaving rivers located towards the northern end of the Strait of Georgia ecosystem migrated strictly northwards after ocean entry, but those from rivers towards the southern end displayed split-route migration patterns within populations, with some moving southward. CONCLUSIONS/SIGNIFICANCE: Our results reveal a tremendous diversity of behavioural migration strategies used by juvenile salmon, across species, rearing histories, and habitats, as well as within individual populations. During the downstream migration, factors that had strong

    In the present paper, occurrence of post noon F3 layers over Thiruvananthapuram (8.5°N; 77°E; dip latitude ∼ 1.5 °N), a dip equatorial station in India have been investigated. F3 layers that occur beyond 13 IST and as observed using ground based ionosonde, for the years 2004-2008 have been studied. Our analysis shows that post noon F3 layers occur mostly on CEJ days around 16 IST to 18 IST. It is found that the time of the ionospheric E-region electric field reversal as inferred from collocated ground based magnetometer observations plays a crucial role in the generation of post noon F3 layers. In fact an early reversal of electric field emerged to be the necessary condition for the formation of post noon F3 layers. A time delay of three to 4 h is observed between the electric field reversal and the formation of F3 layer. It is proposed that this early reversal causes enhanced ionization over dip equatorial region, providing an additional ion drag to the flow of thermospheric zonal wind. This leads to accumulation of more ionization and neutrals culminating in the generation of post noon F3 layers as in the case of pre noon F3 layers. These results reveal that the generation of post noon F3 layers over the dip equatorial region is a natural consequence of the variability associated with the spatio-temporal evolution of EIA and prevailing thermospheric and ionospheric dynamics, and adds a new perspective to the present understanding.

    We examine the financial and time burdens associated with caring for children with chronic conditions, focusing on disparities across types of conditions. Using linked data from the 2003 to 2006 National Health Interview Survey and 2004-2008 Medical Expenditure Panel Survey, we created measures of financial burden (out-of-pocket healthcare costs, the ratio of out-of-pocket healthcare costs to family income, healthcare costs paid by insurance, and total healthcare costs) and time burden (missed school time due to illness or injury and the number of doctor visits) associated with 14 groups of children's chronic conditions. We used the two-part model to assess the effect of condition on financial burden and finite mixture/latent class model to analyze the time burden of caregiving. Controlling for the influences of other socio-demographic characteristics on caregiving burden, children with chronic conditions have higher financial and time burdens relative to caregiving burdens for healthy children. Levels of financial burden and burden sharing between families and insurance system also vary by type of condition. For example, children with pervasive developmental disorder or heart disease have a relatively low financial burden for families, while imposing a high cost on the insurance system. In contrast, vision difficulties are associated with a high financial burden for families relative to the costs borne by others. With respect to time burden, conditions such as cerebral palsy and heart disease impose a low time burden, while conditions such as pervasive developmental disorder are associated with a high time burden. This study demonstrates that differences exist in caregiving burden for children by type of chronic condition. Each condition has a unique profile of time and financial cost burden for families and the insurance system. These results have implications for policymakers and for families' savings and employment decisions.

    Activity restriction is extensively prescribed for pregnant women with major comorbidities despite the lack of evidence to support its effectiveness in preventing preterm birth or low birth weight. To determine the moderation effect of home activity restriction for more than a week on infant's birth weight and gestational age at birth for high-risk women with obstetrical and medical comorbidities. A secondary analysis of 2004-2008 New York Pregnancy Risk Assessment Monitoring System was conducted with 1426 high-risk women. High-risk group included 41% of women treated with activity restriction and 59% of those not treated with activity restriction. Women with preterm premature rupture of membrane (PPROM) who were treated with activity restriction had a lower infant birth weight ( b = -202.85, p = ≤.001) and gestational age at birth ( b = -.91, p = ≤.001) than those without activity restriction. However, women with preterm labor and hypertensive disorders of pregnancy who were not treated with activity restriction had lower infant gestational age at birth ( b = -96, p = ≤.01) and ( b = -92, p = ≤.001), respectively, compared to those who were treated with activity restriction. Findings suggest a contrary effect of activity restriction on infants born to women with PPROM, which is a major reason for prescribing activity restriction. The current study results may trigger the need to conduct randomized control trials to determine the effect of severity of activity restriction on maternal and infant outcomes.

    2013-01-01

    Recent scholarship argues that successful international medical collaboration depends crucially on improving cross-cultural understanding. To this end, this study analyzes recent writings on medical ethics by physicians in two countries actively participating in global medicine, Thailand and the United States. Articles (133; published 2004-2008) from JAMA, the New England Journal of Medicine, and the Journal of the Medical Association of Thailand are analyzed to inductively build a portrait of two discursive ethical cultures. Frameworks of moral reasoning are identified across and within the two groups, with a focus on what authority (religion, law, etc.) is invoked to define and evaluate ethical problems. How might similarities and differences in ethical paradigms reflect the countries' historical "semicolonial" relationship, shed light on debates about Eastern vs. Western bioethics, and facilitate or hinder contemporary cross-national communication? Findings demonstrate substantial overlap in Thai and American doctors' vocabulary, points of reference, and topics covered, though only Thai doctors emphasize national interests and identity. American authors display a striking homogeneity in styles of moral reasoning, embracing a secular, legalistic, deontological ethics that generally eschews discussion of religion, personal character, or national culture. Among Thai authors, there is a schism in ethical styles: while some hew closely to the secular, deontological model, others embrace a virtue ethics that liberally cites Buddhist principles and emphasizes the role of doctors' good character. These two approaches may represent opposing reactions-assimilation and resistance, respectively-to Western influence. The current findings undermine the stereotype of Western individualism versus Eastern collectivism. Implications for cross-national dialog are discussed. Copyright © 2012 Elsevier Ltd.

    Gout commonly involves joint inflammation, and clinical epidemiological studies on involved tendons are scant. Rotator cuff tears are the most common cause of shoulder disability, and surgery is one of the choices often adopted to regain previous function. To investigate the risk of receiving rotator cuff repair surgery among patients with gout and to analyze possible risk factors to design an effective prevention strategy. Cohort study; Level of evidence, 3. The authors studied a 7-year longitudinal follow-up of patients from the Taiwan Longitudinal Health Insurance Database 2005 (LHID2005). This included a cohort of patients who received a diagnosis of gout during 2004-2008 (gout cohort) and a cohort matched by propensity scores (control cohort). A 2-stage approach that used the National Health Interview Survey 2005 was used to obtain missing confounding variables from the LHID2005. The crude hazard ratio (HR) and adjusted HR were estimated between the gout and control cohorts. The gout and control cohorts comprised 32,723 patients with gout and 65,446 people matched at a ratio of 1:2. The incidence of rotator cuff repair was 31 and 18 per 100,000 person-years in the gout and control cohorts, respectively. The crude HR for rotator cuff repair in the gout cohort was 1.73 (95% confidence interval [CI], 1.23-2.44; P gout cohort. Further analysis revealed that the adjusted HR was 1.73 (95% CI, 1.20-2.50; P gout who did not take hypouricemic medication and 2.70 (95% CI, 1.31-5.59; P gout aged 50 years or younger. Patients with gout, particularly those aged 50 years or younger and without hypouricemic medication control, are at a relatively higher risk of receiving rotator cuff repair surgery. Strict control of uric acid levels with hypouricemic medication may effectively reduce the risk of rotator cuff repair.

    The year 2004 was characterized by achievement of the quantitative goals established early in the year and by consolidation of the differential objectives derived from the Corporate Project, a reference framework on which we have been basing our operations for some years and that we have used to establish an Operating Plan that sets the most important objectives for the five-year period of 2004-2008. In this plan, we try to maintain the results considered as good and succeed in keeping them among those obtained by the best plants with our technology. The load factor obtained in 2004 (98.9%) is the best historical result of our plant. Likewise, the collective dose indicator (226 mSvxh) is the best historical datum. This result allows us to maintain a position of leadership in the group of plants similar to ours. All this is the result of ALARA action improvement studies developed during job preparation and planning and of the upgrading and modernization of equipment and installations. A planned maintenance outage during the month of April has helped to achieve these results. A detailed job planning made it possible to satisfactory complete different activities on schedule, including servicing of the mechanical pressure regulator, maintenance of a main steam isolation valve, and replacement of the two primary recirculation pumps. The figure of operating indicator correspond to the month of December summarizes the results achieved during 2004. The graphic includes the three differential follow-up objectives: Strengthening of the Safety Culture, Operating License Renewal and Improvement In-Plant Task Management. (Author)

    To present a case study on how to compare various matching methods applying different measures of balance and to point out some pitfalls involved in relying on such measures. Administrative claims data from a German statutory health insurance fund covering the years 2004-2008. We applied three different covariance balance diagnostics to a choice of 12 different matching methods used to evaluate the effectiveness of the German disease management program for type 2 diabetes (DMPDM2). We further compared the effect estimates resulting from applying these different matching techniques in the evaluation of the DMPDM2. The choice of balance measure leads to different results on the performance of the applied matching methods. Exact matching methods performed well across all measures of balance, but resulted in the exclusion of many observations, leading to a change of the baseline characteristics of the study sample and also the effect estimate of the DMPDM2. All PS-based methods showed similar effect estimates. Applying a higher matching ratio and using a larger variable set generally resulted in better balance. Using a generalized boosted instead of a logistic regression model showed slightly better performance for balance diagnostics taking into account imbalances at higher moments. Best practice should include the application of several matching methods and thorough balance diagnostics. Applying matching techniques can provide a useful preprocessing step to reveal areas of the data that lack common support. The use of different balance diagnostics can be helpful for the interpretation of different effect estimates found with different matching methods. © Health Research and Educational Trust.

    Full Text Available The precise and accurate quantitative evaluation of the temporal and spatial pattern of carbon (C storage in forest ecosystems is critical for understanding the role of forests in the global terrestrial C cycle and is essential for formulating forest management policies to combat climate change. In this study, we examined the C dynamics of forest ecosystems in Shaanxi, northwest China, based on four forest inventories (1989-1993, 1994-1998, 1999-2003, and 2004-2008 and field-sampling measurements (2012. The results indicate that the total C storage of forest ecosystems in Shaanxi increased by approximately 29.3%, from 611.72 Tg in 1993 to 790.75 Tg in 2008, partially as a result of ecological restoration projects. The spatial pattern of C storage in forest ecosystems mainly exhibited a latitude-zonal distribution across the province, increasing from north (high latitude to south (low latitude generally, which signifies the effect of environmental conditions, chiefly water and heat related factors, on forest growth and C sequestration. In addition, different data sources and estimation methods had a significant effect on the results obtained, with the C stocks in 2008 being considerably overestimated (864.55 Tg and slightly underestimated (778.07 Tg when measured using the mean C density method and integrated method, respectively. Overall, our results demonstrated that the forest ecosystem in Shaanxi acted as a C sink over the last few decades. However, further studies should be carried out with a focus on adaption of plants to environmental factors along with forest management for vegetation restoration to maximize the C sequestration potential and to better cope with climate change.

    This paper presents a novel and simple method of seismic envelope analysis that can be applied at multiple scales, e.g. field, m to km scale and laboratory, mm to cm scale, and utilises the diffusive approximation of the seismic wavefield (Wegler, 2003). Coefficient values for diffusion and attenuation are obtained from seismic coda energies and are used to describe the rate at which seismic energy is scattered and attenuated into the local medium around a receiver. Values are acquired by performing a linear least squares inversion of coda energies calculated in successive time windows along a seismic trace. Acoustic emission data were taken from piezoelectric transducers (PZT) with typical resonance frequency of 1-5MHz glued around rock samples during deformation laboratory experiments carried out using a servo-controlled triaxial testing machine, where a shear/damage zone is generated under compression after the nucleation, growth and coalescence of microcracks. Passive field data were collected from conventional geophones during the 2004-2008 eruption of Mount St. Helens volcano (MSH), USA where a sudden reawakening of the volcanic activity and a new dome growth has occurred. The laboratory study shows a strong correlation between variations of the coefficients over time and the increase of differential stress as the experiment progresses. The field study links structural variations present in the near-surface geology, including those seen in previous geophysical studies of the area, to these same coefficients. Both studies show a correlation between frequency and structural feature size, i.e. landslide slip-planes and microcracks, with higher frequencies being much more sensitive to smaller scale features and vice-versa.

  7. Assessment of wastewater treatment facility compliance with decreasing ammonia discharge limits using a regression tree model.

    2017-11-15

    A regression tree-based diagnostic approach is developed to evaluate factors affecting US wastewater treatment plant compliance with ammonia discharge permit limits using Discharge Monthly Report (DMR) data from a sample of 106 municipal treatment plants for the period of 2004-2008. Predictor variables used to fit the regression tree are selected using random forests, and consist of the previous month's effluent ammonia, influent flow rates and plant capacity utilization. The tree models are first used to evaluate compliance with existing ammonia discharge standards at each facility and then applied assuming more stringent discharge limits, under consideration in many states. The model predicts that the ability to meet both current and future limits depends primarily on the previous month's treatment performance. With more stringent discharge limits predicted ammonia concentration relative to the discharge limit, increases. In-sample validation shows that the regression trees can provide a median classification accuracy of >70%. The regression tree model is validated using ammonia discharge data from an operating wastewater treatment plant and is able to accurately predict the observed ammonia discharge category approximately 80% of the time, indicating that the regression tree model can be applied to predict compliance for individual treatment plants providing practical guidance for utilities and regulators with an interest in controlling ammonia discharges. The proposed methodology is also used to demonstrate how to delineate reliable sources of demand and supply in a point source-to-point source nutrient credit trading scheme, as well as how planners and decision makers can set reasonable discharge limits in future.

    Decision-making on invasive intervention in patients with clinical signs of infected necrotizing pancreatitis is often related to the presence of gas configurations and the degree of encapsulation in necrotic collections on imaging. Data on the natural history of gas configurations and encapsulation in necrotizing pancreatitis are, however, lacking. A post hoc analysis was performed of a previously described prospective cohort in 21 Dutch hospitals (2004-2008). All computed tomography scans (CTs) performed during hospitalization for necrotizing pancreatitis were categorized per week (1 to 8, and thereafter) and re-assessed by an abdominal radiologist. A total of 639 patients with necrotizing pancreatitis were included, with median four (IQR 2-7) CTs per patient. The incidence of first onset of gas configurations varied per week without a linear correlation: 2-3-13-11-10-19-12-21-12%, respectively. Overall, gas configurations were found in 113/639 (18%) patients and in 113/202 (56%) patients with infected necrosis. The incidence of walled-off necrosis increased per week: 0-3-12-39-62-76-93-97-100% for weeks 1-8 and thereafter respectively. Clinically relevant walled-off necrosis (largely or fully encapsulated necrotic collections) was seen in 162/379 (43%) patients within the first 3 weeks. Gas configurations occur in every phase of the disease and develop in half of the patients with infected necrotizing pancreatitis. Opposed to traditional views, clinically relevant walled-off necrosis occurs frequently within the first 3 weeks.

    The purpose of this paper was to describe the epidemiology of foodborne outbreaks in Poland in 2010. The evaluation of the epidemiological situation was based on data from outbreak investigation forms, reported by Sanitary and Epidemiological Stations to the Department of Epidemiology, NIPH-NIH. In 2010 a notable increase in the number of cases reported with a bacterial infection was observed. This increase however did not exceeded the median number of cases reported in 2004-2008. In 2010 392 foodborne infections and food poisoning involving 6994 cases (outbreaks involving 4 person or more) and 145 foodborne outbreaks (where 2-3 persons became ill were reported. S. Enteritidis was the most frequently etiological agent in outbreaks associated with bacterial infection (32.9% of outbreaks 22.4% cases). Viruses caused 26% of outbreaks affected 30% of cases. In 38.3% outbreaks the etiological agent could not be established. The main vehicle of foodborne outbreaks were meals prepared from (> 3) raw meats (4.6% of outbreaks, 10.9% cases) and meals prepared using milk and eggs (9.9% of outbreaks 5.7% cases). The most frequent places of contamination included farms who produced goods for human consumption (11.5% of outbreaks, 5.0% of cases). Private residences (113 outbreaks with 745 cases) and hospitals were the most common place where food poisoning outbreaks occurred. In 2010 there were 6 outbreaks where more than 100 people were affected in these settings. Like in previous years, in 2010 the etiological agents, vehicle and sources of infection were not identified in most foodborne outbreaks. In order to decrease the number of outbreaks with undetermined etiological agent, the spectrum of routine laboratory tests of samples taken in outbreaks should be broaden.

    One of the most striking features of the ongoing conflict in the Democratic Republic of Congo (DRC) is the use of sexual violence. In spite of the brutality of these crimes, the experiences of women affected by sexual violence in Eastern DRC remain poorly characterized. This analysis aimed to (1) provide detailed demographics of sexual violence survivors presenting to Panzi Hospital; (2) examine how demographic factors might impact patterns of sexual violence; and (3) describe care-seeking behavior among sexual violence survivors. The demographics and care-seeking behavior of sexual violence survivors in South Kivu Province were described from a retrospective registry-based study of sexual violence survivors presenting to Panzi Hospital (2004-2008). A total of 4311 records were reviewed. The mean age of survivors was 35 years. Most women (53%) were married, self-identified with the Bashi tribe (65%), and reported agriculture as their livelihood (74%). The mean time delay between sexual assault and seeking care was 10.4 months. Five reasons were identified to help explain the lengthy delays to seeking care: waiting for physical symptoms to develop or worsen before seeking medical attention, lack of means to access medical care, concerns that family would find out about the sexual assault, stigma surrounding sexual violence, and being abducted into sexual slavery for prolonged periods of time. Many sexual assault survivors have very delayed presentations to medical attention. Promoting timely access of medical care may best be facilitated by reducing stigma and by educating women about the benefits of early medical care, even in the absence of injuries or symptoms.

    Sand dune migration is documented with a readily-available tool (Google Earth) near Chott El Gharsa, just north-west of Tozeur, Tunisia. As fiducial markers we employ a set of buildings used to portray the fictional city Mos Espa. This set of ~ 20 buildings over roughly a hectare was constructed in 1997 for the movie Star Wars Episode 1 - The Phantom Menace. The site now lies between the arms of a large “pudgy” barchan dune, which has been documented via satellite imaging in 2002, 2004, 2008 and 2009 to have moved from ~ 140 m away to only ~ 10 m away. Visits by the authors to the site in 2009 and 2011 confirm the barchan to be in a threatening position: a smaller set nearby was substantially damaged by being overrun by dunes circa 2004. The migration rate of ~ 15 m/yr decreases over the observation period, possibly as a result of increased local rainfall, and is consistent with barchan migration rates observed at other locations worldwide. The migration rate of this and two other barchans suggests sand transport of ~ 50 m3/m/yr, somewhat higher than would be suggested by traditional wind rose calculations: we explore possible reasons for this discrepancy. Because of the link to popular science fiction, the site may be of pedagogical interest in teaching remote sensing and geomorphic change. We also note that nearby playa surfaces and agricultural areas have a time-variable appearance. The site's popularity as a destination for Star Wars enthusiasts results in many photographs being posted on the internet, providing a rich set of in-situ imagery for continued monitoring in the absence of dedicated field visits.

    Approximately 0.04% of the general population will present with a complication related to Meckel diverticulum. The classic teaching is that symptomatic children with Meckel diverticulum present with painless rectal bleeding and are evaluated with a radionuclide scan. Our subjective experience is that we see children with Meckel diverticulum who present with abdominal pain and are evaluated by CT. We reviewed the findings on CT in children with pathologically proven Meckel diverticulum to identify characteristic patterns of presentation. Databases were searched (2004-2008) for all children who had a pathologic diagnosis of Meckel diverticulum and a CT scan performed prior to surgery. Demographics, pathology, and CT features were reviewed. CT features reviewed included: soft-tissue stranding, abnormal calcifications, bowel obstruction, free air, free peritoneal fluid, cystic mass, intussusception, obvious lead point, location, and whether a normal appendix was identified. The frequency of Meckel diverticulum encountered on CT scans was compared to that found during the same period of time on technetium pertechnetate studies. The review identified 16 subjects (mean age 9.5 years, M:F 9:7). CT findings included: soft-tissue stranding in nine (56%), small-bowel obstruction (SBO) in nine (56%), intussusception in three (19%), free fluid in ten (63%), cystic mass in four (25%), calcification in none (0%), free air in one (6%), and no abnormalities in two (13%). A normal appendix was identified in only five children (31%). There were three basic patterns of presentation of abnormalities: SBO only in five, intussusception with SBO in three, or cystic mass with inflammatory stranding in four (one with SBO). Also, 2.3 times more Meckel diverticulum was encountered on CT than on technetium pertechnetate studies. Meckel diverticulum is currently more commonly encountered in children on CT performed for abdominal pain than on technetium pertechnetate studies. There are three

    Opium use, particularly in low doses, is a common practice among adults in northeastern Iran. We aimed to investigate the association between opium use and subsequent mortality from disorders of the digestive tract. We used data from the Golestan Cohort Study, a prospective cohort study in northeastern Iran, with detailed, validated data on opium use and several other exposures. A total of 50,045 adults were enrolled during a 4-year period (2004-2008) and followed annually until December 2012, with a follow-up success rate of 99%. We used Cox proportional hazard regression models to evaluate the association between opium use and outcomes of interest. In all, 8,487 (17%) participants reported opium use, with a mean duration of 12.7 years. During the follow-up period 474 deaths from digestive diseases were reported (387 due to gastrointestinal cancers and 87 due to nonmalignant etiologies). Opium use was associated with an increased risk of death from any digestive disease (adjusted hazard ratio (HR)=1.55, 95% confidence interval (CI)=1.24-1.93). The association was dose dependent, with a HR of 2.21 (1.57-3.31) for the highest quintile of cumulative opium use vs. no use (Ptrend=0.037). The HRs (95% CI) for the associations between opium use and malignant and nonmalignant causes of digestive mortality were 1.38 (1.07-1.76) and 2.60 (1.57-4.31), respectively. Increased risks were seen both for smoking opium and for ingestion of opium. Long-term opium use, even in low doses, is associated with increased risk of death from both malignant and nonmalignant digestive diseases.

    Cereals provide 50 % of protein and calorie essential for nutrition. Cereals contribution to total daily food consumption can go up to 3/4, if their role in animal feeding has also been considered. Of the 41 % of crop plants are cereals and their share in food production is as high as 98 %. Combination of high yielding cultivars and adequate management techniques is primary to increase yield in unit area. Crossing is the most common breeding method to develop new cultivars. Mutation has been important as a direct or complemental technique to crossing in plant breeding. Mutation is an effective method to expand existent gene pools for breeding purposes. It has been proved as a successful and effectual method by widely grown mutant cereal varieties. Considering these successful examples, Saraykoey Nuclear Research and Training Center started a durum wheat mutation breeding program in 2002. Main goal of the program is to develop durum wheat lines/varieties with high adaptation to drought and cold, high yield and quality, and short length. Kunduru 1149 has been used as parent cultivar. Kunduru 1149 had 11 % seed moisture content and 98 % germination rate. Seeds were irradiated with 50, 150, 250 Gy of gamma rays from a 6 0Co source and 0,002-0,004 EMS doses of individual and bulk applications for growth rooms and field experiments, respectfully. M1 plants of field experiment had been transplanted to the several field days after the treatment. M2 generation seeds were harvested from fertile spikes of M1 plants and planted to field in the next growing season in 2003. Selections based on the program goals were made throughout M3-M6 generations in 2004-2008. Preliminary field yield trials have been in progress with selected mutant lines of M6 generation based on their quality analysis.

    51 organizations network in SARNET (Severe Accident Research NETwork of Excellence) their capacities of research in order to resolve the most important remaining uncertainties for enhancing, in regard of Severe Accidents (SA), the safety of existing and future Nuclear Power Plants (NPPs). This project, co-funded by the European Commission (EC), has been defined in order to optimise the use of the available means and to constitute sustainable research groups in the European Union. SARNET tackles the fragmentation that exists between the different R and D national programmes, in defining common research programmes and developing common computer tools and methodologies for safety assessment. SARNET comprises most of the actors involved in SA research in Europe (plus Canada). To reach these objectives, all the organizations networked in SARNET contribute to a so-called Joint Programme of Activities (JPA), which consists in: Implementing an advanced communication tool for accessing all project information, fostering exchange of information, and managing documents; Harmonizing and re-orienting the research programmes; Jointly analysing the experimental results provided by research programmes in order to elaborate a common understanding of relevant phenomena; Developing the ASTEC code (integral computer code used to predict the NPP behaviour during a postulated SA), which capitalizes in terms of physical models the knowledge produced within SARNET; Developing Scientific Databases, in which all the results of research programmes are stored in a common format (DATANET); Developing a common methodology for Probabilistic Safety Assessment (PSA) of NPPs; Developing courses and writing a text book on SA for students and researchers; Promoting personnel mobility between various European organizations. After the first period (2004-2008), co-funded by the EC, the network will progressively evolve toward self-sustainability. The bases for such an evolution, still under discussion

    Hourly air quality data covering the period 2004-2008 was obtained from the Air Quality Division, the Department of Environment (DOE) through long-term monitoring by Alam Sekitar Sdn. Bhd. (ASMA) were analysed to investigate the variations of surface ozone (O3) in the Klang Valley, Malaysia. A total of nine monitoring stations were selected for analysis in this study and the results show that there are distinct seasonal patterns in the surface O3 across the Klang Valley. A high surface O3 concentration is usually observed between January and April, while a low surface O3 concentration is found between June and August. Analysis of daily variations in surface O3 and the precursors - NO, NO2, CO, NMHC and UVb, indicate that the surface O3 photochemistry in this study area exhibits a positive response to the intensity and wavelength in UVb while being influenced by the concentration of NOx, particularly through tritration processes. Although results from our study suggested that NMHCs may influence the maximum O3 concentration, further investigation is required. Wind direction during different monsoons was found to influence the concentration of O3 around the Klang Valley. HYSPLIT back trajectories (-72 h) were used to indicate the air-mass transport patterns on days with high concentrations of surface O3 in the study area. Results show that 47% of the high O3 days was associated with the localized circulation. The remaining 32% and 22% were associated with mid-range and long-range transport across the South China Sea from the northeast.

    Full text: Soybean variety improvement for high seed protein using induced mutation was initiated. Approximately 5,000 seeds of soybean variety Chiang Mai 60 were irradiated with gamma rays at the dose of 200 Grays at Kasetsart University. High-protein seed mutants in M2 to M4 generations were selected at Nakhon Ratchasima Field Crops Research Center during 2004-2008. The Pedigree method of selection was used. Kjeldahl method was used to analyze seed protein percentages. The M2 seeds protein content of the M2 generation was 45.2% while that of the original parent was 43.0%. M3s were seeded plant to row. In each row, the best four plants were selected for protein analysis. The average protein content of selected mutant lines was 3.9% while the check variety had average protein content of 42.4%. In the M4 generation, the result showed that the average protein contents of the selected mutant lines and the check variety were 42.8% and 42.0%, respectively. In the 2007-2008 trials, four promising mutants had and average protein content of 428%, while the check variety had and average protein content of 41.1%. The four mutants produced the mean grain yield of 2.20-2.42 t/Ha, which was 10.21% higher than that of Chiang Mai 60. The mutant lines produced both a high grain protein content and a high grain yield. They will be further tested their adaptability in the research centers and farmer fields

    Recent studies suggest that prevalence of diagnosed diabetes in the United States reached a plateau or slowed around 2008, and that this change coincided with obesity plateaus and increases in physical activity. However, national estimates can obscure important variations in geographic subgroups. We examine whether a slowing or leveling off in diagnosed diabetes, obesity, and leisure time physical inactivity prevalence is also evident across the 3143 counties of the United States. We used publicly available county estimates of the age-adjusted prevalence of diagnosed diabetes, obesity, and leisure-time physical inactivity, which were generated by the Centers for Disease Control and Prevention (CDC). Using a Bayesian multilevel regression that included random effects by county and year and applied cubic splines to smooth these estimates over time, we estimated the average annual percentage point change (APPC) from 2004 to 2008 and from 2008 to 2012 for diabetes, obesity, and physical inactivity prevalence in each county. Compared to 2004-2008, the median APPCs for diabetes, obesity, and physical inactivity were lower in 2008-2012 (diabetes APPC difference = 0.16, 95%CI 0.14, 0.18; obesity APPC difference = 0.65, 95%CI 0.59, 0.70; physical inactivity APPC difference = 0.43, 95%CI 0.37, 0.48). APPCs and APPC differences between time periods varied among counties and U.S. regions. Despite improvements, levels of these risk factors remained high with most counties merely slowing rather than reversing, which suggests that all counties would likely benefit from reductions in these risk factors. The diversity of trajectories in the prevalence of these risk factors across counties underscores the continued need to identify high risk areas and populations for preventive interventions. Awareness of how these factors are changing might assist local policy makers in targeting and tracking the impact of efforts to reduce diabetes, obesity and physical inactivity.

    Analyse mortality differences between self-employed and paid employees with a focus on industrial sector, educational level and gender using Swedish register data. A cohort of the total working population (4 776 135 individuals; 7.2% self-employed; 18-100 years of age at baseline 2003) in Sweden with a 5-year follow-up (2004-2008) for all-cause and cause-specific mortality (57 743 deaths). Self-employed individuals were categorised as sole proprietors or limited liability company (LLC) owners according to their enterprise's legal form. Cox proportional hazards models were applied to compare mortality rates between sole proprietors, LLC owners and paid employees, adjusted for sociodemographic confounders. Mortality from cardiovascular diseases was 16% lower and from suicide 26% lower among LLC owners than among paid employees, adjusted for confounders. Within the industrial category, all-cause mortality was 13-15% lower among sole proprietors and LLC owners compared with employees in manufacturing and mining (MM) as well as personal and cultural services (PCS), and 11-20% higher in sole proprietors in trade, transport and communication and the welfare industry (W). A significant three-way interaction indicated 17-23% lower all-cause mortality among male LLC owners in MM and female sole proprietors in PCS, and 50% higher mortality in female sole proprietors in W than in employees in the same industries. Mortality differences between self-employed individuals and paid employees vary by the legal form of self-employment, across industries, and by gender. Differences in work environment exposures and working conditions, varying market competition across industries and gender segregation in the labour market are potential mechanisms underlying these findings.

    Interest in improving quality and effectiveness is the primary driver for health information exchange efforts across a health care system to improve the provision of public health care services. The aim here was to describe and identify the impact of a regional health information exchange (HIE) using quantitative statistics for 2004-2008 in one hospital district in Finland. We conducted a comparative, longitudinal 5-year follow-up study to evaluate the utilization rates of HIE, and the impact on health care delivery outcomes. The selected outcomes were total laboratory tests, radiology examinations, appointments, emergency visits, and referrals. The HIE utilization rates increased annually in all 10 federations of municipalities, and the viewing of reference information increased steadily in each professional group over the 5-year study period. In these federations, a significant connection was found to the number of laboratory tests and radiology examinations, with a statistically significant increase in the number of viewed references and use of HIE. The higher the numbers of emergency visits and appointments, the higher the numbers of emergency referrals to specialized care, viewed references, and HIE usage among the groups of different health care professionals. There is increasing interest in HIE usage through regional health information system among health professionals to improve health care delivery regionally and bring information on the patient directly to care delivery. It will be important to study which changes in working methods in the service system are explained by RHIS. Also, the experiences of the change that has taken place should be studied among the different stakeholders, administrative representatives, and patients.

    Although a number of new species of Babesia/Theileria have been described recently, there are still relatively few reports of species from Africa. In this study based on the evaluation of morphology and phylogenetic relationships, we describe a novel species from Wagner's gerbil, Babesia behnkei n. sp. Rodents (n = 1021) were sampled in four montane valleys (wadies) in 2000, 2004, 2008 and 2012 in the Sinai Mountains, Egypt. The overall prevalence of Babesia spp. was highest in the Wagner's gerbil (Dipodillus dasyurus; 38.7%) in comparison to the prevalence in the spiny mice species, Acomys dimidiatus and A. russatus. Morphological investigations were conducted for the comparison of trophozoites of the novel species of Babesia with the B. microti King's 67 reference strain. Thirty-two isolates derived from D. dasyurus over a 9 year period (2004-2012) from two wadies (29 isolates from Wadi Gebel and 3 from Wadi El-Arbaein) were investigated by microscopic, molecular and phylogenetic analysis. A near-full-length sequence of the 18S rRNA gene and the second internal transcribed spacer (ITS2) region were amplified, sequenced and used for the construction of phylogenetic trees. A novel species of Babesia was identified in two isolated populations of D. dasyurus. Phylogenetic analysis of 18S rDNA and ITS2 sequences revealed that B. behnkei n. sp. is most closely related to B. lengau from cheetahs from South Africa and to Nearctic species found only in North America (the pathogenic B. duncani and B. conradae) and that it is more distant to the cosmopolitan rodent parasite B. microti. Trophozoites of B. behnkei were smaller and less polymorphic than trophozoites of B. microti. Babesia behnkei n. sp. is a novel species of the 'Duncani group' maintained in isolated populations of Dipodillus dasyurus occurring in the Sinai Mountains of Egypt.

    Using data from the China Kadoorie Biobank study, we conducted a prospective investigation on the association between type 2 diabetes mellitus (T2DM) and cancer risk in Chinese adults. A total of 508,892 participants (mean (standard deviation) age = 51.5 (10.7) years) without prior cancer diagnosis at baseline (2004-2008) were included. We documented 17,463 incident cancer cases during follow-up until December 31, 2013. Participants with T2DM had increased risks of total and certain site-specific cancers, and the hazard ratio (HR) was 1.13 (95% confidence interval (CI): 1.07, 1.19) for total cancer, 1.51 (1.29, 1.76) for liver cancer, 1.86 (1.43, 2.41) for pancreatic cancer, and 1.21 (1.01, 1.47) for female breast cancer. The associations were largely consistent when doctor-diagnosed and screen-detected T2DM were analyzed separately, except for colorectal cancer (HR = 0.91 (95% CI: 0.73, 1.13) for doctor-diagnosed T2DM, and HR = 1.44 (95% CI: 1.18, 1.77) for screen-detected T2DM). In participants without prior diagnosis of T2DM, higher random blood glucose levels were positively associated with risk of total cancer, liver cancer, and female breast cancer (all P for trend ≤0.02). In conclusion, T2DM is associated with an increased risk of new-onset cancer in China, particularly cancers of the liver, pancreas, and female breast. © The Author(s) 2018.

    Full Text Available The paper deals with the psychological issues of the Russian sport in general (including internal and external, objective and subjective ones. The attitudes of the most authoritative sports experts are analyzed. Various media discuss the performance of Russians in the Olympics of the third Millennium, the role and importance of psychology in modern sport and also in preparation of elite sport athletes for such important tournaments as the Olympic Games. The paper discusses fundamental differences of psychological preparation of the Russian and foreign athletes, comparative analysis of national team performances of Russia in the summer Olympics and Paralympic Games over the past 20 years, i.e. in 1996, 2000, 2004, 2008 and 2012. The paper analyses the strongest team performances on the global level in the latest Summer Olympic games and the probabilistic prediction of the performance results in the Summer Olympics in Brazil in reference with November doping scandal in the Russian Athletics Federation associated with charges of the Russian athletes in the mass doping followed by a loud dismissal of a number of sports officials and coaches, with two Russian athletes to be disqualified and stripped of their medals of London Olympics-2012, and also a RAF member in the IAAF to be suspended, which puts into question the possibility of Russian national athletics team participating in the next Olympics. The paper outlines current problematic issues the solution of which is urgent for the 21st Summer Olympics 2016 in Rio de Janeiro, Brazil, and should contribute to a fundamental change in the psychological, spiritual, moral atmosphere not only of an individual athlete, but for all Russian sport in general.

    Full Text Available In general, the Mediterranean forests have suffered high levels of fragmentation, mainly by anthropogenic action, as result of the productive activities of agriculture and livestock, human settlements and forest plantations of fast growing exotic species, leading to loss of continuity of natural forests, and thus a decrease of biodiversity. In this context, the objective of this study was to evaluate the potential use of satellite images and Geographic Information Systems (GIS to quantify and characterize the spatial evolution of native forests in a semi-arid landscape area at the Region of Maule, Chile. The study was conducted with Landsat-5 TM images of 2004 and 2008, which were classified by the supervised method where it was previously necessary to apply the atmospheric and the geometric corrections to reduce errors of interpretation and measurement. Within the analysis, it was incorporated digital thematic information of land use of the National Forestry Corporation (CONAF and also it was joined one of the latest techniques derived from remote sensing for studying changes in land cover, that is called Radiometric Rotation Controlled by No-Change Axis (RCNA. Finally, the fragmentation indexes were estimated for characterizing the spatial configuration of landscape. From the results of the digital classification it was possible to estimate landscape metrics that show significant differences in the structure of the study area between the two periods. In addition, it was generated an image of change 2004/2008 that allowed to evaluate the consistency of the RCEN technique, demonstrating the feasibility of using this alternative methodology for the detection of changes in terms of degradation and recovery of woodlands.

    Sylvia Cardoso Leão

    Full Text Available BACKGROUND: An extended outbreak of mycobacterial surgical infections occurred in Brazil during 2004-2008. Most infections were caused by a single strain of Mycobacterium abscessus subsp. bolletii, which was characterized by a specific rpoB sequevar and two highly similar pulsed-field gel electrophoresis (PFGE patterns differentiated by the presence of a ∼50 kb band. The nature of this band was investigated. METHODOLOGY/PRINCIPAL FINDINGS: Genomic sequencing of the prototype outbreak isolate INCQS 00594 using the SOLiD platform demonstrated the presence of a 56,267-bp [corrected] circular plasmid, designated pMAB01. Identity matrices, genetic distances and phylogeny analyses indicated that pMAB01 belongs to the broad-host-range plasmid subgroup IncP-1β and is highly related to BRA100, pJP4, pAKD33 and pB10. The presence of pMAB01-derived sequences in 41 M. abscessus subsp. bolletii isolates was evaluated using PCR, PFGE and Southern blot hybridization. Sixteen of the 41 isolates showed the presence of the plasmid. The plasmid was visualized as a ∼50-kb band using PFGE and Southern blot hybridization in 12 isolates. The remaining 25 isolates did not exhibit any evidence of this plasmid. The plasmid was successfully transferred to Escherichia coli by conjugation and transformation. Lateral transfer of pMAB01 to the high efficient plasmid transformation strain Mycobacterium smegmatis mc(2155 could not be demonstrated. CONCLUSIONS/SIGNIFICANCE: The occurrence of a broad-host-range IncP-1β plasmid in mycobacteria is reported for the first time. Thus, genetic exchange could result in the emergence of specific strains that might be better adapted to cause human disease.

    While the progressive improvement of hygiene situations in the workplaces has taken to a reduction of chemical carcinogens exposure, in recent years in Italy the number of compensated occupational cancer resulting from carcinogens exposures of distant decades, has been increasing. Nevertheless, several experiences suggest that the proportion of occupational cancers unrecognised and not notified, as required by law, still remains important. This contribution concerns some experiences, performed between 2004-2008 by the Local Occupational Health Service (SPSAL) located in a highly industrialised province, on the working sector of rubber, iron and steel industry, the asphalt working and the poultry stock-breeders. This work concerns the following issues: - the evaluation of carcinogens exposure; - technical preventive measures and personal protection; - the level of workers' information and formation and the registration of exposed workers; - the characterization of work-related cancer. The results of the 5 years of activity allow us to underline that, in the most of 49 plants involved in the study, the carcinogens exposure evaluation and the prevention and protection measures were lacking. Information of workers was largely deficient and the registration of exposed workers was absent. A major attention to detect and to evaluate the work-related cancer has allowed us to recognize 50 new cases in the iron-steel industries and 21 new cases in a rubber industry. Although this experience concerns only few occupational fields, it provides the basis to call for a greater commitment of SPSAL addressed to companies and general practitioners to both, the promotion and surveillance of the correct procedures of carcinogens exposure evaluation and his prevention, and the active detection of occupational cancer, still missing.

    The authors applied a time-series approach to assess the temporal trend of racial disparity in chlamydia prevalence between young, socioeconomically disadvantaged blacks and whites entering the US National Job Training Program. Racial disparity was defined as the arithmetic difference between age group-, specimen type-, and region of residence-standardized chlamydia prevalences in blacks and whites. A regression with autoregressive moving average errors model was employed to adjust for serial correlation. Data from 46,849 women (2006-2008) and 136,892 men (2004-2008) were analyzed. Racial disparity significantly decreased among women (by an average of 0.122% per 2-month interval; P < 0.05) but not among men (-0.010%, P = 0.57). Chlamydia prevalence significantly declined for black women (-0.139% per 2-month interval; P = 0.004), black men (-0.045%, P < 0.001), and white men (-0.035%, P = 0.002) but not for white women (-0.028%, P = 0.413). Despite the decreases among black women and black men, the black-white disparities remained high for both sexes; in 2008, the racial disparity was 8.1% (95% confidence interval: 6.8, 9.3) for women and 9.0% (95% confidence interval: 8.4, 9.6) for men. These findings suggest that current chlamydia control efforts may be reaching young black men and women but need to be scaled up or modified to address the excess risk among blacks.

    Colonoscopy plays a critical role in colorectal cancer (CRC) screening and has been widely regarded as the gold standard. Cecal intubation rate (CIR) is one of the well-defined quality indicators used to assess colonoscopy. To assess the impact of new technologies on the quality of colonoscopy by assessing completion rates. This was a dual-center study at the 2 nd Department of Surgery at Jagiellonian University Medical College and at the Specialist Center "Medicina" in Krakow, Poland. The CIR and cecal intubation time (CIT) in three different eras of technological advancement were determined. The study enrolled 27 463 patients who underwent colonoscopy as part of a national CRC screening program. The patients were divided into three groups: group I - 3408 patients examined between 2000 and 2003 (optical endoscopes); group II - 10 405 patients examined between 2004 and 2008 (standard electronic endoscopes); and group III - 13 650 patients examined between 2009 and 2014 (modern endoscopes). There were statistically significant differences in the CIR between successive eras. The CIR in group I (2000-2003) was 69.75%, in group II (2004-2008) was 92.32%, and in group III (2009-2014) was 95.17%. The mean CIT was significantly reduced in group III. Our study shows that the technological innovation of novel endoscopy devices has a great influence on the effectiveness of the CRC screening program. The new era of endoscopic technological development has the potential to reduce examination-related patient discomfort, obviate the need for sedation and increase diagnostic yields.

    The talk addresses the feasibility and difficulties of research projects to reach out and to integrate a sufficient number of stakeholders (vgl. Carrada, 2006; Poulsen, 2007; Zikos et al. 2012; Lee & Belohlav, 2014). With "stakeholders" we understand end-users, policy makers, students for capacity building, administrators and interested general public. The design and later the implementation of stakeholder integration and public engagement strongly depend on the priority-setting and requirements of funding agencies (EU [1], DFG, BMBF and the regional ministries in Germany). They affect the size and constellation of consortia as well as the longevity and continuity of research community; on the other hand they also determine the weighting of communication, dissemination, outreach (and networking) activities within the project. For instance by public engagement of EU funded projects a share of 10% for communication and outreach activities was rated as best practices in 2014 [2]. On the national level there is no such appointment so far. In our talk we will quantify and compare activities among selected EU and nationally funded collaborative projects in Germany, address the hurdles, investigate the communication tools, examine the outreach channels and dissemination tactics, reflect the performances and the results achieved so far, with the objective to answer the following questions: - What tools/channels have been applied so far? Were they efficient and expedient? - What can be count as best practices? - Are such activities sustainable at all? The goal of this talk is to show the complexity of the stakeholder integration and public engagement in research projects, to critically assess our experiences gained in past and running projects, and to subsequently have an interactive exchange with other project professionals at EGU.

    We assessed the prevalence and characteristics of prescription drug misuse among youth ages 15-25 to examine differences by student and employment status, and associations with workplace antidrug policies and programs. Multivariate logistic regressions analyzed associations in weighted data on the 20,457 young adults in the combined 2004-2008 National Surveys on Drug Use and Health. Demographic controls included sex, race, community size, and age group. After we accounted for demographic controls, at ages 15-25, students were less likely than nonstudents to misuse prescription drugs. Segmenting student from nonstudent groups, working consistently was associated with a further reduction in misuse for those ages 18-25. When we controlled for demographics and substance use history, both Employee Assistance Program (EAP) services and awareness that one's employer had a drug-free workplace policy were associated with significantly lower misuse of prescription drugs (OR = 0.85 for each program, 95% CI [0.73, 1.00] and [0.72, 1.00]). Associations of workplace antidrug policies and programs with marijuana use and with Diagnostic and Statistical Manual for Mental Disorders, Fourth Edition, criteria for alcohol abuse and dependence contrasted sharply with these patterns. All four aspects were significantly associated with lower marijuana use. None was associated with problem drinking. Protective effects of drug-free workplace policy and EAPs persist after other substance use was controlled for. Comparing the effects of workplace programs on illicit drug use and problem drinking versus prescription misuse suggests that those protective associations do not result from selection bias. Thus, drug-free workplace policies and EAPs appear to help protect younger workers against prescription misuse. If workplace substance use disorder programs focused prevention messages and interventions on prescription drug misuse, their impact on misuse might increase.

Dynamic relationship among vegetable oils and crude oil is investigated using vector error correction model (VECM. The data is monthly price data from January 1980 to December 2008, consist of price of the most produced vegetable oils, i.e. palm oil, soyabean oil and rapeseed oil. Crude oil price (CPO was taken into account since biodiesel converted from vegetable oils has become an important alternative of fuel. To get picture of dynamic interrelationship among vegetable oils and crude oil during commodity price soar period, this study was divided into period of investigation, which is period 1980-2003 (before commodity price soar and period 2004-2008 (during commodity price soar.  This study indicates that there is cointegration between vegetable oils and crude oil, and vegetable oils were influenced by crude oil especially in commodity price soar period.

    Full Text Available Mountain forests in National park Bohemian Forest (Czech Republic were affected by bark beetle attack and windthrows in 2004-2008, followed by an extensive tree dieback. We evaluated changes in the biochemistry of the uppermost soil horizons with the emphasis on carbon (C and nitrogen (N cycling in a near-natural spruce (Picea abies mountain forest after the forest dieback, and compared it with an undisturbed control plot of similar age, climate, elevation, deposition, N-saturation level, and land use history. We hypothesised that the high litter input after forest dieback at the disturbed plot and its consequent decomposition might influence the availability of C for microorganisms, and consequently, N transformations in the soil. The concentrations of dissolved organic C (DOC and N (DON in soil water extracts rapidly increased at the disturbed plot for 3 yeas and then continually decreased. Net ammonification exhibited a similar trend as DOC and DON, indicating elevated mineralization. Despite the high ammonium concentrations found after the forest dieback (an increase from 0.5 mmol kg-1 to 2-3 mmol kg-1, net nitrification was stable and low during these 3 years. After the DOC depletion and decrease in microbial biomass 5 years after the forest dieback, net nitrification started to rise, and nitrate concentrations increased from 0.2-1 mmol kg-1 to 2-3 mmol kg-1. Our results emphasize the key role of the availability of organic C in microbial N transformations, which probably promoted microbial heterotrophic activity at the expense of slow-growing nitrifiers.

    The present study analysed data derived from the 2004-2008 Nutrition and Health Survey in Taiwan, conducted by the Ministry of Health and Welfare, to understand the relationship among eating-out behaviour, related non-nutritional factors and osteopenia in the Taiwanese population. Design/Setting/Subjects Data of 1140 adults who had been evaluated with dual-energy X-ray absorptiometry in June 2007 were included. The data were analysed through descriptive and inferential statistics to determine the association of osteopenia with the frequency of eating out, demographic variables (i.e. age, sex, level of education, marital status and place of birth), BMI, waist circumference and food consumption. Gender, age, education level, personal income and waist circumference were all factors found to be significantly associated with eating-out frequency and the incidence of osteopenia. Eating-out frequency was negatively associated with the incidence of osteopenia. Individuals with BMI>27 kg/m2 had a lower frequency of eating out and a lower incidence of osteopenia. Individuals with a lower monthly income had a significantly greater chance of developing osteopenia. Men living without spouses had significantly higher chances of osteopenia. Ca intake was negatively associated with breakfast eating-out frequency. Eating-out frequency was not associated with an increasing incidence of osteopenia, but affected the Ca intake in the Taiwanese population. Having a balanced selection of food is crucial to reduce the incidence of osteopenia. Improving nutritional knowledge for those under higher risk of osteopenia is necessary to prevent osteopenia and Ca deficiency.

Debido a esta grave problemática, desde el año 2008 se ha venido utilizando un sistema de alerta temprana por movimientos en masa inducidos por lluvia soportado en umbrales de lluvia empíricos. Estos sistemas proporcionan un rápido medio para monitorear y comunicar información sobre amenazas a una comunidad vulnerable, por lo que se usan para proteger vidas, señalando con anterioridad la posibilidad de un evento, lo que proporciona tiempo para tomar acciones que pueden reducir las condiciones de riesgo. Este artículo describe la definición y ajuste del modelo, al igual que presenta los resultados de la validación de los umbrales para el periodo 2004-2008. Los resultados encontrados indican que, aunque el modelo ajustado predice la ocurrencia de un alto porcentaje de eventos para la ciudad de Medellín, existe aún un gran número de eventos que se presentan en condiciones normales, lo cual indica que se requiere la definición de umbrales que se ajusten a las condiciones locales del valle y reduzcan los niveles de incertidumbre propios de un modelo estocástico.No vale de Aburrá as complexas condições físicas do território, somadas aos altos índices de vulnerabilidade, propiciaram cenários com um alto potencial de perdas humanas e econômicas ante a ocorrência de fenômenos de origem natural tais como movimentos em massa, os quais representam 35 % dos eventos que ocorrem no vale e 77 % das vítimas fatais.

    Full Text Available OBJETIVO: Diseñar un instrumento para elaborar corredores o canales endémicos mediante cálculos sencillos y, en el caso de enfermedades transmisibles, identificar y estimar parámetros relacionados con la dinámica de la transmisión. MÉTODOS: Se obtuvieron parámetros para elaborar una curva teórica de incidencia esperada, basada en el modelo logístico de crecimiento. Los parámetros se estimaron por medio de una regresión no lineal, a partir de datos de incidencia acumulada de los cinco años anteriores. Se tomó como ejemplo la incidencia semanal acumulada de casos de enfermedad tipo influenza para Argentina en 2009 y se la comparó con la serie de casos de 2004 a 2008 para construir los canales endémicos acumulados y no acumulados. RESULTADOS: De acuerdo a los canales endémicos acumulados obtenidos, el país entró en zona de brote a partir de la semana dos. El máximo número esperado de casos o capacidad de carga (K de acuerdo a los datos de años previos fue de 1 090 660. Considerando los corredores no acumulados, la situación de brote se presentó en 34 de las 51 semanas. Se estimó un rango para la tasa básica de reproducción (R0 de 1,05 a 1,13 para el período no epidémico 2004-2008. CONCLUSIONES: El nuevo método permitió elaborar canales endémicos de una manera sencilla, con la obtención de parámetros importantes para la transmisión. Si bien tiene limitaciones, entre ellas que la ecuación utilizada es más útil para evaluar enfermedades con un ciclo anual marcado y menos exacta para ciclos menores de un año, puede ser considerado como una alternativa valiosa para elaborar corredores endémicos y una nueva contribución al estudio de brotes epidémicos en los niveles locales de vigilancia de la salud.OBJECTIVE: Design an instrument for determining endemic levels or ranges using simple calculations; identify and estimate the parameters related to the dynamic transmission of communicable diseases.

    Full Text Available Purpose: The library of Henrik Tuma, kept at the Research Station ZRC SAZU (Raziskovalna postaja ZRC SAZU in Nova Gorica, is nowadays considered to be one of the best preserved private libraries arising in the region of Gorica at the turn of the 19th century. The article tries to evaluate and encompass all the richness of the collection thus giving an insight in the reading culture and book production in Gorica and in the wider Slovenia. It also points out to the fact that the library was closely connected to the European cultural and ideological trends as the books were supplied by all important publishing centres in Europe.Methodology/approaach: The article gives an analysis of the library catalogue created in the period 2004-2008 (electronic version was published in 2013. The overview of the major subject areas of the collection defines the place (the Goriška region and time (from the end of the 19th century to the thirties of the 20th century of building the collection.Results: The evaluation of the subject areas and the analysis of the catalogue give an insight in the present state of the collection which differs from Tuma’s inventory of the collection. It is evident that it is one of the best preserved private libraries arising in the region of Gorica at the turn of the 19th century.Research limitation: Many publications (monographs, periodicals inventoried in the old Tuma’s register were excluded from the 2008 catalogue as they were proved to be missing or lost.

    Full Text Available BACKGROUND: Recent decades have witnessed an increase in mean maternal age at childbirth in most high-resourced countries. Advanced maternal age has been associated with several adverse maternal and perinatal outcomes. Although there are many studies on this topic, data from large contemporary population-based cohorts that controls for demographic variables known to influence perinatal outcomes is limited. METHODS: We performed a population-based cohort study using data on all singleton births in 2004-2008 from the North Western Perinatal Survey based at The University of Manchester, UK. We compared pregnancy outcomes in women aged 30-34, 35-39 and ≥40 years with women aged 20-29 years using log-linear binomial regression. Models were adjusted for parity, ethnicity, social deprivation score and body mass index. RESULTS: The final study cohort consisted of 215,344 births; 122,307 mothers (54.19% were aged 20-29 years, 62,371(27.63% were aged 30-34 years, 33,966(15.05% were aged 35-39 years and 7,066(3.13% were aged ≥40 years. Women aged 40+ at delivery were at increased risk of stillbirth (RR = 1.83, [95% CI 1.37-2.43], pre-term (RR = 1.25, [95% CI: 1.14-1.36] and very pre-term birth (RR = 1.29, [95% CI:1.08-1.55], Macrosomia (RR = 1.31, [95% CI: 1.12-1.54], extremely large for gestational age (RR = 1.40, [95% CI: 1.25-1.58] and Caesarean delivery (RR = 1.83, [95% CI: 1.77-1.90]. CONCLUSIONS: Advanced maternal age is associated with a range of adverse pregnancy outcomes. These risks are independent of parity and remain after adjusting for the ameliorating effects of higher socioeconomic status. The data from this large contemporary cohort will be of interest to healthcare providers and women and will facilitate evidence based counselling of older expectant mothers.

    To study the clinical characteristics, pathogenic bacteria, and antibiotics resistance of neonatal purulent meningitis in order to provide the guide for early diagnosis and appropriate treatment. A retrospective review was performed and a total of 112 cases of neonatal purulent meningitis (male 64, female 58) were identified in the neonatal intensive care unit of Yuying Children's Hospital of Wenzhou Medical University seen from January 1, 2004 to December 31, 2013. The clinical information including pathogenic bacterial distribution, drug sensitivity, head imageology and therapeutic outcome were analyzed. Numeration data were shown in ratio and chi square test was applied for group comparison. Among 112 cases, 46 were admitted from 2004 to 2008 and 66 from 2009 to 2013, 23 patients were preterm and 89 were term, 20 were early onset (occurring within 3 days of life) and 92 were late onset meningitis (occurring after 3 days of life). In 62 (55.4%) cases the pathogens were Gram-positive bacteria and in 50 (44.6%) were Gram-negative bacteria. The five most frequently isolated pathogens were Escherichia coli (32 cases, 28.6%), coagulase-negative staphylococcus (CNS, 20 cases, 17.9%), Streptococcus (18 cases, 16.1%, Streptococcus agalactiae 15 cases), Enterococci (13 cases, 11.6%), Staphylococcus aureus (9 cases, 8.0%). Comparison of pathogenic bacterial distribution between 2004-2008 and 2009-2013 showed that Gram-positive bacteria accounted for more than 50% in both period. Escherichia coli was the most common bacterium, followed by Streptococcus in last five years which was higher than the first five years (22.7% (15/66) vs. 6.5% (3/46), χ(2) = 5.278, P bacteria in early onset meningitis and higher than those in late onset meningitis (35.0% (7/20) vs. 12.0% (11/92), χ(2) = 4.872, P pathogens responsible for neonatal purulent meningitis over the past ten years. There were increasing numbers of cases with Streptococcus meningitis which are more common in early onset

    Ethiopia joined the Global Polio Eradication Initiative (GPEI) in 1996, and by the end of December 2001 circulation of indigenous Wild Polio Virus (WPV) had been interrupted. Nonetheless, the country experienced multiple importations during 2004-2008, and in 2013. We characterize the 2013 outbreak investigations and response activities, and document lessons learned. The data were pulled from different field investigation reports and from the national surveillance database for Acute Flaccid Paralysis (AFP). In 2013, a WPV1 outbreak was confirmed following importation in Dollo zone of the Somali region, which affected three Woredas (Warder, Geladi and Bokh). Between July 10, 2013, and January 5, 2014, there were 10 children paralyzed due to WPV1 infection. The majorities (7 of 10) were male and below 5 years of age, and 7 of 10 cases was not vaccinated, and 72% (92/129) of < 5 years of old children living in close proximity with WPV cases had zero doses of oral polio vaccine (OPV). The travel history of the cases showed that seven of the 10 cases had contact with someone who had traveled or had a travel history prior to the onset of paralysis. Underserved and inaccessibility of routine immunization service, suboptimal surveillance sensitivity, poor quality and inadequate supplemental immunization were the most crucial gaps identified during the outbreak investigations. Prior to the 2013 outbreak, Ethiopia experienced multiple imported polio outbreaks following the interruption of indigenous WPV in December 2001. The 2013 outbreak erupted due to massive population movement and was fueled by low population immunity as a result of low routine immunization and supplemental Immunization coverage and quality. In order to avert future outbreaks, it is critical that surveillance sensitivity be improved by establishing community-based surveillance systems and by assigning surveillance focal points at all level particularly in border areas. In addition, it is vital to set

Diante do exposto este trabalho teve o objetivo realizar um levantamento retrospectivo sobre a ocorrência da cisticercose bovina, diagnosticada através do exame post-mortem pelo Serviço de Inspeção Federal do Estado do Paraná entre os anos de 2004 a 2008, além de determinar a distribuição dos casos no Estado, identificar as regiões com maiores chances de apresentarem casos da doença e analisar a perda econômica do Estado por conta das condenações por esta parasitose. Foi constatada prevalência de 2,23% cisticercose bovina no estado do Paraná. Durante o período analisado ocorreu uma redução estatisticamente significante (p<0,05 da prevalência de cisticercose bovina no estado. Nos anos de 2004-2008 foram condenadas 29.708.550 kg de carne bovina por cisticercose, acarretando prejuízos de ordem econômica. O estado do Paraná está conseguindo através da implantação do programa de controle do complexo teníase-cisticercose, uma evolução positiva já que conseguiu durante o período analisado diminuir a prevalência desta parasitose nos bovinos e consequentemente diminuir as perdas econômicas.

    Previous studies have reported associations between prenatal cell phone use and child behavioral problems, but findings have been inconsistent and based on retrospective assessment of cell phone use. This study aimed to assess this association in a multi-national analysis, using data from three cohorts with prospective data on prenatal cell phone use, together with previously published data from two cohorts with retrospectively collected cell phone use data. We used individual participant data from 83,884 mother-child pairs in the five cohorts from Denmark (1996-2002), Korea (2006-2011), the Netherlands (2003-2004), Norway (2004-2008), and Spain (2003-2008). We categorized cell phone use into none, low, medium, and high, based on frequency of calls during pregnancy reported by the mothers. Child behavioral problems (reported by mothers using the Strengths and Difficulties Questionnaire or Child Behavior Checklist) were classified in the borderline/clinical and clinical ranges using validated cut-offs in children aged 5-7years. Cohort specific risk estimates were meta-analyzed. Overall, 38.8% of mothers, mostly from the Danish cohort, reported no cell phone use during pregnancy and these mothers were less likely to have a child with overall behavioral, hyperactivity/inattention or emotional problems. Evidence for a trend of increasing risk of child behavioral problems through the maternal cell phone use categories was observed for hyperactivity/inattention problems (OR for problems in the clinical range: 1.11, 95%CI 1.01, 1.22; 1.28, 95%CI 1.12, 1.48, among children of medium and high users, respectively). This association was fairly consistent across cohorts and between cohorts with retrospectively and prospectively collected cell phone use data. Maternal cell phone use during pregnancy may be associated with an increased risk for behavioral problems, particularly hyperactivity/inattention problems, in the offspring. The interpretation of these results is unclear

We hypothesized that participants in D:A:D at high (>5% predicted risk for both CVD and CKD would be at even greater risk for CVD and CKD events.We included all participants with complete risk factor (covariate data, baseline eGFR > 60 ml/min/1.73 m2, and a confirmed (>3 months apart eGFR 1%-5%, >5% and fitted Poisson models to assess whether CVD and CKD risk group effects were multiplicative.

Participants' CVD and CKD risk groups had multiplicative predictive effects, with no evidence of an interaction (p = 0.329 and p = 0.291 for CKD and CVD, respectively. The main study limitation is the difference in the ascertainment of the clinically defined CVD endpoints and the laboratory-defined CKD endpoints.We found that people at high predicted risk for both CVD and CKD have substantially greater risks for both CVD and CKD events compared with those at low predicted risk for both outcomes, and compared to those at high predicted risk for only CVD or CKD events.

    The aim was to study road-related injuries and fatalities in under 15 year olds in two time periods (1996-2000 and 2004-2008 inclusive) to assess whether progress has been made via cross-sectoral efforts to reduce this injury toll in Ireland. For pedestrian and car-related accidents, police assistance is required and at the time a detailed CT 68 form is completed by the attending officer and sent to the Road Safety Authority for analysis. Details re the severity of injury, light and road conditions and safety measures such as seat belt or car restraint use, seat position and helmet use if a cyclist were recorded. Injuries were sub-classified as fatalities, serious (detained in hospital, fractures, severe head injury, severe internal injuries or shock requiring treatment) or minor. All data for the two time periods was entered onto an SPSS database. A concerted national campaign re road safety media campaign allied to random breath testing, penalty points for driving offences, on the spot fines for speeding and far greater police enforcement took place between the two time frames and continues to this day. When looked at as most likely estimates of death ratios the results were found to be statistically significant with an overall p value of < 0.0001 CI [0.39, 0.69]. When broken down into specific age ranges all were significant apart from the 0-3 age range with a p value of 0.69 CI [0.26, 1.1]. The most significant changes were found in the 7-9 years, 10-12 and 13-15 year age ranges with p values of < 0.0001, 0.0002 and 0.0007 respectively. When results were compared between the two cohorts, car occupant fatalities between both groups dropped by 36%. Pedestrian injuries dropped from 1719 to 1232, pedestrian fatalities decreased by almost 50% as did serious pedestrian injuries from 261 down to 129. Cyclist fatalities saw the most significant fall (76%) with a dramatic reduction in cyclist injuries from 25 down to 6 (63%). The 13-15 year old age group had the highest

    Full Text Available Abstract Background Methicillin-resistant Staphylococcus aureus (MRSA has emerged as a prevalent pathogen of necrotizing fasciitis (NF in Taiwan. A four-year NF cases and clinical and genetic differences between hospital acquired (HA- and community-acquired (CA-MRSA infection and isolates were investigated. Methods A retrospective study of 247 NF cases in 2004-2008 and antimicrobial susceptibilities, staphylococcal chromosomal cassette mec (SCCmec types, pulsed field gel electrophoresis (PFGE patterns, virulence factors, and multilocus sequence typing (MLST of 16 NF-associated MRSA in 2008 were also evaluated. Results In 247 cases, 42 microbial species were identified. S. aureus was the major prevalent pathogen and MRSA accounted for 19.8% of NF cases. Most patients had many coexisting medical conditions, including diabetes mellitus, followed by hypertension, chronic azotemia and chronic hepatic disease in order of decreasing prevalence. Patients with MRSA infection tended to have more severe clinical outcomes in terms of amputation rate (p S. aureus or non-S. aureus infection. NF patients infected by HA-MRSA had a significantly higher amputation rate, comorbidity, C-reactive protein level, and involvement of lower extremity than those infected by CA-MRSA. In addition to over 90% of MRSA resistant to erythromycin and clindamycin, HA-MRSA was more resistant than CA-MRSA to trimethoprim-sulfamethoxazole (45.8% vs. 4%. ST59/pulsotype C/SCCmec IV and ST239/pulsotype A/SCCmec III isolates were the most prevalent CA- and HA-MRSA, respectively in 16 isolates obtained in 2008. In contrast to the gene for γ-hemolysin found in all MRSA, the gene for Panton-Valentine leukocidin was only identified in ST59 MRSA isolates. Other three virulence factors TSST-1, ETA, and ETB were occasionally identified in MRSA isolates tested. Conclusion NF patients with MRSA infection, especially HA-MRSA infection, had more severe clinical outcomes than those infected by

    The Italian National Law 281 of 1991 forbids the euthanatization of free-ranging dogs, unless they have an incurable illness or are proved to be dangerous. Without neglecting the undeniable benefits of the "no-kill" policy, nevertheless it has brought about a chronic overpopulation in shelters and, as a result, higher costs of management and welfare problems since some dogs remain in the shelter for life. In 2004-2008, the Istituto Zooprofilattico Sperimentale of the Lazio and Tuscany regions carried out a survey in the Lazio Region to verify the effects of the Italian National Law 281/91 on free-ranging dog management following 15 years from its implementation. One of the aims of the study was an assessment of the welfare of dogs in a shelter sample (8 shelters out of 47 censused in the Lazio Region). 97 mixed-breed dogs were selected, their behaviour was studied and a blood sample was taken for each dog in order to determine the individual blood concentration of cortisol and the amount of oxidative damage (level of dRoms), as well as the amount of antioxidants to cope with it. Moreover, the total leukocyte count (leukogram) was accomplished. We ran general backward stepwise regression models using "level of antioxidant", "level of dRoms" and "level of serum cortisol" as dependent variables respectively. The results showed that the most important variable that improved the level of welfare of dogs consisted in having the opportunity to regularly go out of the cage for a walk, whereas other variables like gender, size of the cage (small, medium, large), being alone in the cage, and being neutered/entire, had no significant effect on the physiological indicators of welfare. Dogs that enjoyed the regular walk had a higher total antioxidant capacity, and performed a lower frequency of displacing activities and stereotyped behaviour. Moreover, oxidative stress parameters seem to be indicators well matched with behavioural indicators of stress. Thus, for the first time

    European Framework Research Projects have recently added a lot of meaning to the building process of the ERA - the European Research Area. Inside this, the accelerator technology plays an essential role. Accelerator technology includes large infrastructure and intelligent, modern instrumentation embracing mechatronics, electronics, photonics and ICT. During the realization of the European research and infrastructure project FP6 CARE 2004-2008 (Coordinated Accelerator Research in Europe), concerning the development of large accelerator infrastructure in Europe, it was decided that a scientific editorial series of peer-reviewed monographs from this research area will be published in close relation with the projects. It was a completely new and quite brave idea to combine a kind of a strictly research publisher with a transient project, lasting only four or five years. Till then nobody did something like that. The idea turned out to be a real success. The publications now known and valued in the accelerator world, as the (CERN-WUT) Editorial Series on Accelerator Science and Technology, is successfully continued in already the third European project EuCARD2 and has logistic guarantees, for the moment, till the 2017, when it will mature to its first decade. During the realization of the European projects EuCARD (European Coordination for Accelerator R&D 2009-2013 and TIARA (Test Infrastructure of Accelerator Research Area in Europe) there were published 18 volumes in this series. The ambitious plans for the nearest years is to publish, hopefully, a few tens of new volumes. Accelerator science and technology is one of a key enablers of the developments in the particle physic, photon physics and also applications in medicine and industry. The paper presents a digest of the research results in the domain of accelerator science and technology in Europe, published in the monographs of the European Framework Projects (FP) on accelerator technology.

    To investigate the associations of major depressive disorder with coronary heart disease (CHD) and stroke in Chinese adults aged 30-79 years. In 2004-2008, China Kadoorie Biobank was conducted in 10 geographically defined regions (5 urban and 5 rural) of China. A total number of 512 891 participants aged 30-79 years were recruited in the baseline survey. A laptop-based electronic questionnaire was administrated face-to-face by trained health workers, collecting the general demographic and socio-economic status, dietary and other lifestyle behaviours (e.g. smoking, alcohol drinking, physical activity), medical history and family history of common chronic diseases. Major depressive episodes (MDE) in the past 12 months were assessed with the World Health Organization composite international diagnostic interview-short form (CIDI-SF). The physical measurements included the heights and weights, which were used to calculate the body mass indexes (BMI).Chi squared and t test were used to compare the differences in participants characteristics according to their major depressive disorder. Logistic models were employed to estimate the odds ratios (OR) and 95% CI of their major depressive disorder with prevalent coronary heart disease and stroke. Among the 512 891 participants, 3 281 (0.6%) showed an MDE in the preceding 12 months, 15 472 (3.0%) reported prevalent CHD, and 8 884 (1.7%) reported prevalent stroke. Major depressive disorder was significantly associated with an increased risk of CHD and risk of stroke. Age- and gender-adjusted ORs (95% CI) were 1.80 (1.53-2.12) for CHD and 2.53 (2.09-3.05) for stroke. The associations were significant after further adjustment for potential confounders, such as other socio-demographic status, smoking, alcohol drinking, physical activity, and BMI, prevalent hypertension, diabetes as well as family history of cardiovascular diseases (OR=1.83, 95% CI=1.54-2.18 for CHD; OR=2.19, 95% CI=1.79-2.69 for stroke).

    The joint U.S-Canadian project has been devoted to: (a) decadal climate studies using developed state-of-the-art GCMs (General Circulation Models) with enhanced variable and uniform resolution; (b) development and implementation of advanced numerical techniques; (c) research in parallel computing and associated numerical methods; (d) atmospheric chemistry experiments related to climate issues; (e) validation of regional climate modeling strategies for nested- and stretched-grid models. The variable-resolution stretched-grid (SG) GCMs produce accurate and cost-efficient regional climate simulations with mesoscale resolution. The advantage of the stretched grid approach is that it allows us to preserve the high quality of both global and regional circulations while providing consistent interactions between global and regional scales and phenomena. The major accomplishment for the project has been the successful international SGMIP-1 and SGMIP-2 (Stretched-Grid Model Intercomparison Project, phase-1 and phase-2) based on this research developments and activities. The SGMIP provides unique high-resolution regional and global multi-model ensembles beneficial for regional climate modeling and broader modeling community. The U.S SGMIP simulations have been produced using SciDAC ORNL supercomputers. The results of the successful SGMIP multi-model ensemble simulations of the U.S. climate are available at the SGMIP web site (http://essic.umd.edu/~foxrab/sgmip.html) and through the link to the WMO/WCRP/WGNE web site: http://collaboration.cmc.ec.gc.ca/science/wgne. Collaborations with other international participants M. Deque (Meteo-France) and J.

  14. Regional nitrous oxide flux in Amazon basin

    Nitrous oxide (N 2 O) is the third most important anthropogenic greenhouse gas. Globally, the main sources of N 2 O are nitrification and denitrification in soils. About two thirds of the soil emissions occur in the tropics and approximately 20% originate in wet rain forest ecosystems, like the Amazon forest. The work presented here involves aircraft vertical profiles of N 2 O from the surface to 4 km over two sites in the Eastern and Central Amazon: Tapajos National Forest (2000-2009) and Cuieiras Biologic Reserve (2004-2007), and the estimation of N 2 O fluxes for regions upwind of these sites using two methods: Column Integration Technique and Inversion Model - FLEXPART. To our knowledge, these regional scale N 2 O measurements in Amazonia are unique and represent a new approach to looking regional scale emissions. For the both methods, the fluxes upwind of Cuieiras Biologic Reserve exhibited little seasonality, and the annual mean was 1.9 ±1.6 mgN 2 Om -2 day -1 for the Column Integration Technique and 2.3±0.9 mgN 2 Om -2 day -1 for Inversion Model - FLEXPART. For fluxes upwind of Tapajos Nacional Forest, the Inversion Model - FLEXPART presented about half (0.9±1.7 mgN 2 Om -2 day -1 ) of the Column Integration Technique (2.0±1.1 mgN 2 Om -2 day -1 ) for the same period (2004-2008). One reason could be because the inversion model does not consider anthropic activities, once it had a good representation for less impacted area. Both regions presented similar emission during wet season. By Column Integration Technique, fluxes upwind Tapajos Nacional Forest were similar for dry and wet seasons. The dry season N 2 O fluxes exhibit significant correlations with CO fluxes, indicating a larger than expected source of N 2 O from biomass burning. The average CO:N 2 O ratio for all 38 profiles sampled during the dry season was 82±69 mol CO:molN 2 O and suggests a larger biomass burning contribution to the global N 2 O budget than previously reported.

    Most of the malaria burden in the Americas is concentrated in the Brazilian Amazon but a detailed spatial characterization of malaria risk has yet to be undertaken. Utilizing 2004-2008 malaria incidence data collected from six Brazilian Amazon states, large-scale spatial patterns of malaria risk were characterized with a novel Bayesian multi-pathogen geospatial model. Data included 2.4 million malaria cases spread across 3.6 million sq km. Remotely sensed variables (deforestation rate, forest cover, rainfall, dry season length, and proximity to large water bodies), socio-economic variables (rural population size, income, and literacy rate, mortality rate for children age under five, and migration patterns), and GIS variables (proximity to roads, hydro-electric dams and gold mining operations) were incorporated as covariates. Borrowing information across pathogens allowed for better spatial predictions of malaria caused by Plasmodium falciparum, as evidenced by a ten-fold cross-validation. Malaria incidence for both Plasmodium vivax and P. falciparum tended to be higher in areas with greater forest cover. Proximity to gold mining operations was another important risk factor, corroborated by a positive association between migration rates and malaria incidence. Finally, areas with a longer dry season and areas with higher average rural income tended to have higher malaria risk. Risk maps reveal striking spatial heterogeneity in malaria risk across the region, yet these mean disease risk surface maps can be misleading if uncertainty is ignored. By combining mean spatial predictions with their associated uncertainty, several sites were consistently classified as hotspots, suggesting their importance as priority areas for malaria prevention and control. This article provides several contributions. From a methodological perspective, the benefits of jointly modelling multiple pathogens for spatial predictions were illustrated. In addition, maps of mean disease risk were

    2009-01-01

    The Belgian Nuclear Research Centre (SCK-CEN) has a long-standing expertise in research concerning the compatibility of waste forms with the final disposal environment, in collaboration with NIRAS/ONDRAS. For high level waste, most attention goes to two waste forms that are relevant for Belgium, namely (1) vitrified HLW (High Level Waste) from the reprocessing of spent fuel, and (2) spent fuel as such, referring to the direct disposal scenario. The expertise lies especially in the study of the chemical interactions between the waste forms and the disposal environment. This is done by laboratory experiments, supported by modeling. Until 2004, the reference disposal design for HLW glass and spent fuel in Belgium was based on the use of a bentonite buffer. The experiments performed in that period therefore involved mostly the study of the influence of clay on the waste form behaviour. Since 2004 the Supercontainer design with Ordinary Portland Cement as buffer material (without bentonite) has been selected as the reference. The experiments related to this new design are therefore predominant now. Clay based disposal designs are still the reference in several other European countries. For this reason, the study of clay-waste interactions was not completely abandoned in the period 2004-2008, but continued in the framework of EC programmes. The first experiments focused on the Supercontainer design were started in 2006 (HLW) and 2007 (spent fuel). The first results are available now for HLW glass. Most results generated recently are, however, still related to the bentonite concept. The objectives of the present study were to evaluate the minimum guaranteed durability of the waste form, which will be used as input in the safety assessment. The objective is not to obtain an absolute value for the durability or an interval of values, which will always be subject to caution, but rather to determine a lower limit for the life time of the waste form, which is conservative

    Full Text Available Purpose: Functionality of feedback in pedagogical processes has been broadly analyzed in face-to-face learning, although to a lesser extent than in the on-line learning. Narciss (2004, 2008 distinguishes two dimensions within the feedback, the semantic dimension and the structural dimension. This article aims to analyze, from the student’s perspective, the semantic dimension of feedback in a virtual learning environment (VLE. Firstly, we analyze the importance that VLE students give to feedback and its degree of personalization. Later, the usefulness that students deem feedback should have, paying special attention to each of its semantic subdimensions (Narciss, 2004. Design/methodology/approach: A survey was conducted among students of Business Administration degree of the Universitat Oberta de Catalunya (UOC. 182 students took part, separated into two groups (pilot and control. Findings: It has been proved that 90% of students give a great or very great importance to reception of feedback from their tutors, a relevance they consider to be higher than the one within a face-to-face environment. This percentage is around 75% with regard to the importance given to the level of personalization of feedback. The development of a factor analysis has revealed that usefulness of personalized feedback perceived by the students can be subsumed under two large dimensions: the one that facilitates learning (related to its semantic dimension and the motivational one (by allowing an easier and more fluid communication with the tutor, contributing not to leave the course, etc. The latter dimension has been also proved to be key in order to attain improvements in the students’ satisfaction with the learning process. This research was funded by the Catalan government and the UOC, within the framework of projects to Improve Teaching Quality (ITQ. Originality/value: Implementing personalized feedback has a relevant impact on the student, who values it because

    To examine the associations between egg consumption and cardiovascular disease (CVD), ischaemic heart disease (IHD), major coronary events (MCE), haemorrhagic stroke as well as ischaemic stroke. During 2004-2008, over 0.5 million adults aged 30-79 years were recruited from 10 diverse survey sites in China. Participants were asked about the frequency of egg consumption and were followed up via linkages to multiple registries and active investigation. Among 461 213 participants free of prior cancer, CVD and diabetes, a total of 83 977 CVD incident cases and 9985 CVD deaths were documented, as well as 5103 MCE. Stratified Cox regression was performed to yield adjusted hazard ratios for CVD endpoints associated with egg consumption. At baseline, 13.1% of participants reported daily consumption (usual amount 0.76 egg/day) and 9.1% reported never or very rare consumption (usual amount 0.29 egg/day). Compared with non-consumers, daily egg consumption was associated with lower risk of CVD (HR 0.89, 95% CI 0.87 to 0.92). Corresponding multivariate-adjusted HRs (95% CI) for IHD, MCE, haemorrhagic stroke and ischaemic stroke were 0.88 (0.84 to 0.93), 0.86 (0.76 to 0.97), 0.74 (0.67 to 0.82) and 0.90 (0.85 to 0.95), respectively. There were significant dose-response relationships of egg consumption with morbidity of all CVD endpoints (P for linear trend <0.05). Daily consumers also had an 18% lower risk of CVD death and a 28% lower risk of haemorrhagic stroke death compared to non-consumers. Among Chinese adults, a moderate level of egg consumption (up to <1 egg/day) was significantly associated with lower risk of CVD, largely independent of other risk factors. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

    Background In the aftermath of the global spread of 2009 influenza A (pH1N1) virus, still very little is known of the early stages of the outbreak in Mexico during the early months of the year, before the virus was identified. Methodology/Main Findings We fit a simple mathematical model, the Richards model, to the number of excess laboratory-confirmed influenza cases in Mexico and Mexico City during the first 15 weeks in 2009 over the average influenza case number of the previous five baseline years of 2004-2008 during the same period to ascertain the turning point (or the peak incidence) of a wave of early influenza infections, and to estimate the transmissibility of the virus during these early months in terms of its basic reproduction number. The results indicate that there may have been an early epidemic in Mexico City as well as in all of Mexico during February/March. Based on excess influenza cases, the estimated basic reproduction number R0 for the early outbreak was 1.59 (0.55 to 2.62) for Mexico City during weeks 5–9, and 1.25 (0.76, 1.74) for all of Mexico during weeks 5–14. Conclusions We established the existence of an early epidemic in Mexico City and in all of Mexico during February/March utilizing the routine influenza surveillance data, although the location of seeding is unknown. Moreover, estimates of R0 as well as the time of peak incidence (the turning point) for Mexico City and all of Mexico indicate that the early epidemic in Mexico City in February/March had been more transmissible (larger R0) and peaked earlier than the rest of the country. Our conclusion lends support to the possibility that the virus could have already spread to other continents prior to the identification of the virus and the reporting of lab-confirmed pH1N1 cases in North America in April.

    The Aerosol Index (AI) observations derived from the Ozone Monitoring Instrument (OMI) on board the Dutch-Finnish Aura satellite are analyzed over Greece covering the whole period of the OMI available data, from September 2004 to August 2008. The objective of this study was to analyze the spatial, seasonal and inter-annual variability of AI over Greece, detected by OMI during 2004-2008, with an evaluation of potential contributing factors, including precipitation and long-range transport (Sahara dust and European pollution). The AI data cover the whole Greek territory (34o-42oN, 20o-28oE) with a spatial resolution of 0.25o x 0.25o (13 km x 24 km at nadir). The results show significant spatial and temporal variability of the seasonal and monthly mean AI, with higher values at the southern parts and lower values over northern Greece. On the other hand, the AI values do not show significant differences between the western and eastern parts and, therefore, the longitude-averaged AI values can be utilized to reveal the strong south-to-north gradient. This gradient significantly changes from season to season being more intense in spring and summer, while it is minimized in winter. Another significant remark is the dominance of negative AI values over northern Greece in the summer months, indicating the presence of non-UV absorbing aerosols, such as sulfate and sea-salt particles. The great geographical extent of the negative AI values in the summer months is indicative of long-range transport of such aerosols. In contrast, the high positive AI values over south Greece, mainly in spring, clearly reveal the UV-absorbing nature of desert-dust particles affecting the area during Saharan dust events. Synoptically, the spatial distribution in OMI-AI values was related to the Saharan dust events mainly over southern Greece and to the trans-boundary-pollution transport, consisting mainly of sulfate particles, in northern Greece. The annual variation of spatial-averaged AI values

    Full Text Available Lifestyle factors are well-known important modifiable risk factors for obesity; the association between tobacco smoking and central obesity, however, is largely unknown in the Chinese population. This study examined the relationship between smoking and central obesity in 0.5 million Chinese adults, a population with a low prevalence of general obesity, but a high prevalence of central obesity.A total of 487,527 adults (200,564 males and 286,963 females, aged 30-79 years, were enrolled in the baseline survey of the China Kadoorie Biobank (CKB Study conducted during 2004-2008. Waist circumference (WC and WC/height ratio (WHtR were used as measures of central obesity.The prevalence of regular smokers was significantly higher among males (60.6% than among females (2.2%. The prevalence of central obesity increased with age and BMI levels, with a significant gender difference (females>males. Of note, almost all obese adults (99.4% were centrally obese regardless of gender. In multivariable regression analyses, adjusting for age, education, physical activity, alcohol use and survey site, regular smoking was inversely associated with BMI in males (standardized regression coefficients, β= -0.093, p<0.001 and females (β= -0.025, p<0.001. Of interest, in the BMI stratification analyses in 18 groups, all βs of regular smoking for WHtR were positive in both genders; the βs showed a significantly greater increasing trend with increasing BMI in males than in females. In the analyses with model adjustment for BMI, the positive associations between regular smoking and WHtR were stronger in males (β= 0.021, p<0.001 than in females (β= 0.008, p<0.001 (p<0.001 for gender difference. WC showed considerably consistent results.The data indicate that tobacco smoking is an important risk factor for central obesity, but the association is gender-specific and depends on the adjustment for general obesity.

    The aim was to study road-related injuries and fatalities in under 15-year-olds in three time periods (1996-2000, 2004-2008 and 2009 -2013 respectively) to assess whether progress has been made via cross-sectoral efforts (legislation, public awareness campaigns and police enforcement) to reduce this injury toll in Ireland. For road traffic collisions where an injury has occurred, police assistance is required and at the time a detailed CT 68 form is completed by the attending police officer and sent to the Road Safety Authority for analysis. Details regarding the severity of injury, light and road conditions and safety measures such as seat belt or car restraint use, seat position and helmet use if a cyclist is involved are recorded. Injuries were sub-classified as fatalities, serious (detained in hospital, fractures, severe head injury, severe internal injuries or shock requiring treatment) or minor. All data for the three time periods was entered onto an SPSS database. A concerted national campaign re road safety media campaign allied to random breath testing, penalty points for driving offences, on the spot fines for speeding and greater police enforcement took place over the 17-year timeframe and continues to this day. When results were compared between the three cohorts, total injuries dropped from 5928 (1996-2000) to 3903 (2009-2013).Fatal injuries dropped from 163 to 43 with car occupant fatalities fell from 69 to 17 between 1996-2000 and 2009-2013. Serious injuries dropped from 347 in the first cohort to 201 in the third cohort. Minor injuries fell from 5,063 to 3,659 between first and last cohort. Pedestrian injuries dropped from 1719 to 1258 with pedestrian fatalities decreased from 61 (1996-2000) to 21 (2009-2013) and serious pedestrian injuries decreased from 261 down to 129. Cyclist fatalities saw the most significant fall (76%) with a dramatic reduction in fatalities from 25 down to 6. A national road safety campaign, greater police enforcement and a

    Dysentery as infective and contagious disease is registered by all EU and EFTA countries only as shigellosis according to etiological classification of the infectious diseases. The cases are also registered by ECDC. According to ECDC Report for 2006-2008 the incidence rate in Poland Sanitary Stations, send to the National Register of Infectious Diseases, evaluated, calculated and published by Department of Epidemiology National Institute of Public Health (NIZP-PZH) in Annual Bulletin "Infections and Intoxications in Poland in 2010", Warsaw NIZP-PZH and GIS (Chief Sanitary Inspectorate ) 2010. Laboratory data were collected as reports from all Regional Sanitary Laboratories send to NIZP-PZH Department of Bacteriology, data from epidemiological investigation of outbreaks including data from identification of Shigella strains obtained from the Reference Laboratory for Gram-negative Bacilli of NIZP-PZH Bacteriology Department. In 2010 thirty cases of shigellosis were registered (incidence was 0.08/100 000 inhabitants) the same number of cases and incidence was observed in 2009, nearly the same in 2008 - 33 cases (incidence 0.09). The numbers were lower than the median in 2004-2008 (64 cases, incidence 0.17/100 000). According to laboratory reports in all 16 Regional Sanitary Stations only 14 persons were Shigella positive, in spite that more than 600 000 were examined: 10 persons were infected by S. sonnei, 4 by S. flexneri. Only one strain of S. sonnei was isolated from a patient with diarrhea. It was in the Regional Sanitary Station laboratory of the małopolskie voievodeshaft. No one strain of S. boydii or S. dysenteriae was isolated. Most of the dysentery cases were examined by other laboratories than laboratories of sanitary epidemiological service. The obligation of private payment for bacteriological examination of suspected cases is one of reason that patient is treated with antibacterial drugs without determination of etiological agent of the infection.

    In order to improve the wave predictions provided in the Black Sea by a wave modelling system based on the SWAN (Simulating Waves Nearshore) spectral model, a technique for assimilating the satellite data has been implemented and evaluated. For this purpose, an approach based on the Optimal Interpolation method has been considered and its results are discussed in the present work. As a first step, SWAN model simulations have been carried out for a 5-year interval (2004-2008). The assimilation is made in terms of the significant wave height (Hs) for each 24 hours considering data coming from 4 satellites (ERS-2, JASON-1, JASON-2, GEOSAT Follow-On). Subsequently, data provided by two other satellites (ENVISAT and TOPEX) are used for validations. To assess the improvement brought in the model predictions by the assimilation scheme, a comparison has been performed between the model results with and without assimilation. The statistical parameters evaluated are: bias, mean absolute error, RMS error, scatter index, correlation coefficient and symmetric slope. The results show that the data assimilation procedure induces a significant improvement of the statistical parameters (lower values for bias, errors and scatter index and values closer to the unity of the correlation coefficient and for the symmetric slope). It was found also that an important factor in improving the wave predictions is represented by the value of the correlation length accounted for the Hs prediction errors (Lmax). Previous studies indicate for this length a value around four degrees in the vicinity of 45 degrees latitude (which corresponds also to the basin of the Black Sea). This value was first considered in the assimilation technique. On the other hand, taking also into account the fact that in the Black Sea the wind-sea waves are dominant, lower values for the parameter Lmax were tested as well and it seems that the most appropriate value for this parameter is between three and four degrees

    There is limited information about the hazards of cigarettes, smokeless tobacco and waterpipe in the Middle East. The aim of this study was to determine the association between different types of tobacco use and earlier death in the Golestan Cohort Study. The Study includes 50 045 adults (aged 40-75 years) from north eastern Iran. The baseline questionnaire (2004-2008) assessed information about use of cigarettes, chewing tobacco (nass) and waterpipe. To assess the use of each type of tobacco compared with never tobacco users, we used Cox regression models adjusted for age, socioeconomic status, area of residence, education and other tobacco used, and stratified by sex, ethnicity and opium use. 17% of participants reported a history of cigarette smoking, 7.5% chewing tobacco (nass) and 1.1% smoking waterpipe, and these figures declined in the later birth cohorts. During a median follow-up of 8 years, 4524 deaths occurred (mean age 64.8+9.9 years). Current (HR=1.44; 95% CI 1.28 to 1.61) and former (HR=1.35; 95% CI 1.16 to 1.56) cigarette smokers had higher overall mortality relative to never tobacco users. The highest cigarette-associated risk was for cancer death among current heavy smokers (HR=2.32; 95% CI 1.66 to 3.24). Current nass chewing was associated with overall mortality (HR=1.16; 95% CI 1.01 to 1.34), and there was a 61% higher risk of cancer death in people chewing nass more than five times a day. We observed an association between the cumulative lifetime waterpipe use (waterpipe-years≥28) and both overall (HR=1.66; 95% CI 1.11 to 2.47), and cancer mortality (HR=2.82; 95% CI 1.30 to 6.11). Regular use of cigarettes, smokeless tobacco and waterpipe were associated with the risk of earlier death (particularly from cancer) in our cohort. Published by the BMJ Publishing Group Limited.

    Aim: To evaluate the breast cancer diagnostic performance after the settlement of a clinical breast and Fine-Needle Aspiration service at the histopathology department of Carlos Manuel Cespedes provincial Hospital in Bayamo (Cuba). Two breast cancer case-series occurred in the period 1992-1995 (127 cases) and 2004-2008 (307 cases) in the 'Carlos Manuel de Cespedes' hospital were compared in order to evaluate the following indicators: proportion of in situ and pT1 cancers, number of lymph nodes from axillary dissection mentioned in the histopathological report, sensitivity of the cytological diagnoses and proportion of conservative surgery in the pT1 tumours . Data were imputed in the software QT (Quality Treatment audit system of breast cancer diagnoses) which includes outcome measures defined by the European Society Of Mastology (EUSOMA); QT was developed by a multidisciplinary team from the European Breast Cancer Network and provided by CPO-Piedmont, Turin (Italy). The Italian NGO Patologi Oltre Frontiera (APOF) was in charge of the improvement of the cytological laboratory and local pathologist's training for breast fine needle aspiration procedures. For the descriptive statistics the QT software was used. No is situ breast cancers were accounted among the 127 patients diagnosed in 1992-95, whereas in the period 2004-08 they were 15 on 307 cases (4.8%). In the latter period lump's mean diameter was mm 27.3 and 158 cases (51.5%) were pT1 cancers; in 1992-95 the mean diameter was mm 29.7 and the pT1 tumours were 60 on 127 (47.2%). In 2004-08 96 on 156 pT1 cancers (63.2%) were treated with conservative surgery which accounted for 17 on the 55 pT1 cases (30.9%) diagnosed in 1992-95 . A number of 9 or more lymph nodes were mentioned in 146 on 250 reports of the period 2004-08 (58.4%); they were 59 on 118 reports of the period 1992-95 (50.0%). The sensitivity of FNA diagnoses in 2004-08 was 72.7%; it was 69.4% in the period 1992-95. There is some evidence that the

    During the early stages of the 2004-2008 Mount St. Helens eruption, the source process that produced a sustained sequence of repetitive long-period (LP) seismic events also produced impulsive broadband infrasonic signals in the atmosphere. To assess whether the signals could be generated simply by seismic-acoustic coupling from the shallow LP events, we perform finite difference simulation of the seismo-acoustic wavefield using a single numerical scheme for the elastic ground and atmosphere. The effects of topography, velocity structure, wind, and source configuration are considered. The simulations show that a shallow source buried in a homogeneous elastic solid produces a complex wave train in the atmosphere consisting of P/SV and Rayleigh wave energy converted locally along the propagation path, and acoustic energy originating from , the source epicenter. Although the horizontal acoustic velocity of the latter is consistent with our data, the modeled amplitude ratios of pressure to vertical seismic velocity are too low in comparison with observations, and the characteristic differences in seismic and acoustic waveforms and spectra cannot be reproduced from a common point source. The observations therefore require a more complex source process in which the infrasonic signals are a record of only the broadband pressure excitation mechanism of the seismic LP events. The observations and numerical results can be explained by a model involving the repeated rapid pressure loss from a hydrothermal crack by venting into a shallow layer of loosely consolidated, highly permeable material. Heating by magmatic activity causes pressure to rise, periodically reaching the pressure threshold for rupture of the "valve" sealing the crack. Sudden opening of the valve generates the broadband infrasonic signal and simultaneously triggers the collapse of the crack, initiating resonance of the remaining fluid. Subtle waveform and amplitude variability of the infrasonic signals as

    Flux towers provide essential terrestrial climate, water, and radiation budget information needed for environmental monitoring and evaluation of climate change impacts on ecosystems and society in general. They are also intended for calibration and validation of satellite-based Earth observation and monitoring efforts, such as assessment of evapotranspiration from land and vegetation surfaces using surface energy balance approaches. In this paper, 15 years of Skukuza eddy covariance data, i.e. from 2000 to 2014, were analysed for surface energy balance closure (EBC) and partitioning. The surface energy balance closure was evaluated using the ordinary least squares regression (OLS) of turbulent energy fluxes (sensible (H) and latent heat (LE)) against available energy (net radiation (Rn) less soil heat (G)), and the energy balance ratio (EBR). Partitioning of the surface energy during the wet and dry seasons was also investigated, as well as how it is affected by atmospheric vapour pressure deficit (VPD), and net radiation. After filtering years with low-quality data (2004-2008), our results show an overall mean EBR of 0.93. Seasonal variations of EBR also showed the wet season with 1.17 and spring (1.02) being closest to unity, with the dry season (0.70) having the highest imbalance. Nocturnal surface energy closure was very low at 0.26, and this was linked to low friction velocity during night-time, with results showing an increase in closure with increase in friction velocity. The energy partition analysis showed that sensible heat flux is the dominant portion of net radiation, especially between March and October, followed by latent heat flux, and lastly the soil heat flux, and during the wet season where latent heat flux dominated sensible heat flux. An increase in net radiation was characterized by an increase in both LE and H, with LE showing a higher rate of increase than H in the wet season, and the reverse happening during the dry season. An increase in

    Thermomechanical pulp (TMP) processes are high energy demanding. This together with the high energy prices of nowadays results in significant costs, why less energy demanding processes are wished. This project has evaluated the potential for energy reductions in a TMP process by a mechanical pre-treatment of the wood chips combined with an enzymatic modification based on a cellulase mixture. The structure of the wood was opened up by the mechanical pre-treatment making it easier for the enzymes to penetrate into the pre-treated wood material. The enzymatic treatment was then run at optimum standard conditions. The EU project - Ecotarget 2004-2008 (www.ecotarget.com) have studied different types of enzymes that could be used for pre-treatment of wood chips in order to save energy during TMP processes. Based on these studies cellulose enzyme was recommended to be used at pre-treatment experiment performed by the Vaermeforsk project. Due to the fact that the Ecotarget-project has also been run during 2008 with activities involving enzymes, the steering board of the Vaermeforsk project took the decision to co-ordinate the experiments from both of the projects. This co-operation increased the funds and also the number of experiments for both of the projects. The experimental results from this project showed that energy reductions at a given tensile index could be achieved if gently mechanical pre-treated wood chips were enzymatically treated. An intensive mechanical pre-treatment gave negative effects on both fibre length and tear index while the light scattering coefficient was promoted, probably due to the fibre shortening. Enzymatic modification of mechanically pre-treated chips showed a favourable modification of the fibres, even regarding the fibre shortening, if compared to mechanical pre-treated chips only. The effects of cellulases was however not as expected, why a high amount of cellulases was used. Other types of enzymes which could attack the primary wall of

  12. Spatial Data Mining for Estimating Cover Management Factor of Universal Soil Loss Equation

    2016-12-01

    Universal Soil Loss Equation (USLE) is a widely used mathematical model that describes long-term soil erosion processes. Among the six different soil erosion risk factors of USLE, the cover-management factor (C-factor) is related to land-cover/land-use. The value of C-factor ranges from 0.001 to 1, so it alone might cause a thousandfold difference in a soil erosion analysis using USLE. The traditional methods for the estimation of USLE C-factor include in situ experiments, soil physical parameter models, USLE look-up tables with land use maps, and regression models between vegetation indices and C-factors. However, these methods are either difficult or too expensive to implement in large areas. In addition, the values of C-factor obtained using these methods can not be updated frequently, either. To address this issue, this research developed a spatial data mining approach to estimate the values of C-factor with assorted spatial datasets for a multi-temporal (2004 to 2008) annual soil loss analysis of a reservoir watershed in northern Taiwan. The idea is to establish the relationship between the USLE C-factor and spatial data consisting of vegetation indices and texture features extracted from satellite images, soil and geology attributes, digital elevation model, road and river distribution etc. A decision tree classifier was used to rank influential conditional attributes in the preliminary data mining. Then, factor simplification and separation were considered to optimize the model and the random forest classifier was used to analyze 9 simplified factor groups. Experimental results indicate that the overall accuracy of the data mining model is about 79% with a kappa value of 0.76. The estimated soil erosion amounts in 2004-2008 according to the data mining results are about 50.39 - 74.57 ton/ha-year after applying the sediment delivery ratio and correction coefficient.

    Full Text Available The study was carried out in sessile oak forests and beech forests in the region central Serbia. The stands are classified as pure stands with the percentage of other species up to 10% per tree number, mixed forests of sessile oak with other species, and mixed forests of beech with other species, whose percentage does not exceed 50%. Altogether 257 stands were monitored - 202 beech stands and 55 sessile oak stands. By the applied method of defining the local heat potential (Lujić, 1960, modified by Ratknić et al. (2001 and Krstić (2004, 2008, which represents possibility of soil heating without vegetation, were determined. In this way, a scale of 162 possible combinations of local heat potential was obtained, which explains more precisely the dependence of beech stands and sessile oak stands on the topographic conditions. By applying the weighted values of the thermal co-ordinates of aspect and slope (E for each altitudinal belt of 100 m, it was concluded that pure stands have the widest ecological range. Pure beech stands occur at the sites with 34 combinations of thermal co-ordinates E.V=4.6 to 8.12. Pure sessile oak stands occur at the sites with 12 combinations of thermal co-ordinates E.V=5.10 to 8.11. The percentage of mixed beech stands with other broadleaf species is the highest at the sites with the co-ordinate V=10-11 (at the altitudes between 700 and 900 m is about 60 %. Mixed stands of sessile oak and beech are located on the terrains with combinations of thermal co-ordinates E.V=7.9 to 8.12. By using the local heat potential of a region, it can be identified which sites, i.e. which combinations of exposure, slope and altitude belong to the particular tree species. Consequently, a more reliable selection of tree species can be done for the bio-reclamation of barrens and other deforested terrains.

    The aim was to study road-related injuries and fatalities in under 15 year olds in two time periods (1996-2000 and 2004-2008 inclusive) to assess whether progress has been made via cross-sectoral efforts to reduce this injury toll in Ireland. For pedestrian and car-related accidents, police assistance is required and at the time a detailed CT 68 form is completed by the attending officer and sent to the Road Safety Authority for analysis. Details re the severity of injury, light and road conditions and safety measures such as seat belt or car restraint use, seat position and helmet use if a cyclist were recorded. Injuries were sub-classified as fatalities, serious (detained in hospital, fractures, severe head injury, severe internal injuries or shock requiring treatment) or minor. All data for the two time periods was entered onto an SPSS database. A concerted national campaign re road safety media campaign allied to random breath testing, penalty points for driving offences, on the spot fines for speeding and far greater police enforcement took place between the two time frames and continues to this day. When looked at as most likely estimates of death ratios the results were found to be statistically significant with an overall p value of < 0.0001 CI [0.39, 0.69]. When broken down into specific age ranges all were significant apart from the 0-3 age range with a p value of 0.69 CI [0.26, 1.1]. The most significant changes were found in the 7-9 years, 10-12 and 13-15 year age ranges with p values of < 0.0001, 0.0002 and 0.0007 respectively. When results were compared between the two cohorts, car occupant fatalities between both groups dropped by 36%. Pedestrian injuries dropped from 1719 to 1232, pedestrian fatalities decreased by almost 50% as did serious pedestrian injuries from 261 down to 129. Cyclist fatalities saw the most significant fall (76%) with a dramatic reduction in cyclist injuries from 25 down to 6 (63%). The 13-15 year old age group had the highest

    As part of the program for the final disposal of the nuclear fuel waste, Posiva Oy investigates the hydrological conditions at the Olkiluoto Island. The hydraulic conductivity in the shallow holes OL-PP36, OL-PP39, OL-PVP4A, OL-PVP4B, OL-PVP6A, OL-PVP6B, OL-PVP14, OL-PVP30, OL-PVP31A, OL-PVP31B, OLPVP32, OL-PVP33, OL-PVP34A, OL-PVP34B, OL-HP1, OL-HP2, OL-HP3 and OLHP4 was measured in summer 2009. The length of PP-holes was between 12 and 14 m, and the test sections (1 m) are located in the bedrock. PVP-tubes have an average length between 3 - 11 m, and the test sections (mostly 2 m) are located in the overburden. The measurements were done using the slug-test technique. In the slug-test, the hydraulic head in the borehole is abruptly changed either by pouring water into the borehole or by lowering the pressure sensor. The hydraulic conductivity is interpreted from the recovery of the water level. This report presents the field measurements and their interpretation. The interpretation has been done using the Hvorslev's method, and for reference, conductivity has also been calculated according to Thiem's equation. According to the results, hydraulic conductivity in PP-holes ranges from 10 -1 0 m/s to 10 -6 m/s and in PVP-tubes from 10 -8 m/s to 10 -5 m/s. The observed range is quite similar as in the previous measurements in 2002 and 2004 - 2008. In general, the results are consistent with the results obtained in earlier measurements. In OL-PVP14, there seems to be a lowering trend of the conductivity. Also, the results agree relatively well with hydraulic conductivity interpreted from the pre-pumping done in connection with the groundwater sampling. (orig.)

    In sub-Saharan Africa, many patients initiate antiretroviral therapy (ART) at CD4 cell counts much lower than those recommended in national guidelines. We examined program-level and contextual-level factors associated with low median CD4 cell count at ART initiation in populations initiating ART. Multilevel analysis of aggregate and program-level service delivery data. We examined data on 1690 cohorts of patients initiating ART during 2004-2008 in eight sub-Saharan African countries. Cohorts with median CD4 less than 111 cells/μl (the lowest quartile) were classified as having low median CD4 cell count at ART initiation. Cohort information was combined with time-updated program-level data and subnational contextual-level data, and analyzed using multilevel models. The 1690 cohorts had median CD4 cell count of 136 cells/μl and included 121,504 patients initiating ART at 267 clinics. Program-level factors associated with low cohort median CD4 cell count included urban setting [adjusted odds ratio (AOR) 2.1; 95% confidence interval (CI) 1.3-3.3], lower provider-to-patient ratio (AOR 2.2; 95% CI 1.3-4.0), no PMTCT program (AOR 3.6; 95% CI 1.0-12.8), outreach services for ART patients only vs. both pre-ART and ART patients (AOR 2.4; 95% CI 1.5-3.9), fewer vs. more adherence support services (AOR 1.6; 95% CI 1.0-2.5), and smaller cohort size (AOR 2.5; 95% CI 1.4-4.5). Contextual-level factors associated with low cohort median CD4 cell count included initiating ART in areas where a lower proportion of the population heard of AIDS, tested for HIV recently, and a higher proportion believed 'limiting themselves to one HIV-uninfected sexual partner reduces HIV risk'. Determinants of CD4 cell count at ART initiation in populations initiating ART operate at multiple levels. Structural interventions targeting points upstream from ART initiation along the continuum from infection to diagnosis to care engagement are needed.

EAACI/GA(2)LEN/EDF/WAO Guideline: definition, classification and diagnosis of urticaria. Allergy 2009;64: 1417-1426), is the result of a consensus reached during a panel discussion at the Third International Consensus Meeting on Urticaria, Urticaria 2008, a joint initiative of the Dermatology Section of the European Academy of Allergology and Clinical Immunology (EAACI), the EU-funded network of excellence, the Global Allergy and Asthma European Network (GA(2)LEN), the European Dermatology Forum (EDF) and the World Allergy Organization (WAO). As members of the panel, the authors had prepared their suggestions regarding management of urticaria before the meeting. The draft of the guideline took into account all available evidence in the literature (including Medline and Embase searches and hand searches of abstracts at international allergy congresses in 2004-2008) and was based on the existing consensus reports of the first and the second symposia in 2000 and 2004. These suggestions were then discussed in detail among the panel members and with the over 200 international specialists of the meeting to achieve a consensus using a simple voting system where appropriate. Urticaria has a profound impact on the quality of life and effective treatment is, therefore, required. The recommended first line treatment is new generation, nonsedating H(1)-antihistamines. If standard dosing is not effective, increasing the dosage up to four-fold is recommended. For patients who do not respond to a four-fold increase in dosage of nonsedating H(1)-antihistamines, it is recommended that second-line therapies should be added to the antihistamine treatment. In the choice of second-line treatment, both their costs and risk/benefit profiles are most important to consider. Corticosteroids are not recommended for

    Hospital-discharged patients with schizoaffective disorder have a high risk of re-hospitalization. However, limited data exist evaluating critical post-discharge periods during which the risk of re-hospitalization is significant. Among hospital-discharged patients with schizoaffective disorder, we assessed pharmacotherapy adherence and healthcare utilization and costs during sequential 60-day clinical periods before schizoaffective disorder-related hospitalization and post-hospital discharge. From the MarketScan(®) Medicaid database (2004-2008), we identified patients (≥18 years) with a schizoaffective disorder-related inpatient admission. Study measures including medication adherence and healthcare utilization and costs were assessed during sequential preadmission and post-discharge periods. We conducted univariate and multivariable regression analyses to compare schizoaffective disorder-related and all-cause healthcare utilization and costs (in 2010 US dollars) between each adjacent 60-day post-discharge periods. No adjustment was made for multiplicity. We identified 1,193 hospital-discharged patients with a mean age of 41 years. The mean medication adherence rate was 46% during the 60-day period prior to index inpatient admission, which improved to 80% during the 60-day post-discharge period. Following hospital discharge, schizoaffective disorder-related healthcare costs were significantly greater during the initial 60-day period compared with the 61- to 120-day post-discharge period (mean US$2,370 vs US$1,765; p schizoaffective disorder-related costs declined during the 61- to 120-day post-discharge period and remained stable for the remaining post-discharge periods (days 121-365). We observed considerably lower (46%) adherence during 60 days prior to the inpatient admission; in comparison, adherence for the overall 6-month period was 8% (54%) higher. Our study findings suggest that both short-term (e.g., 60 days) and long-term (e.g., 6-12 months) medication

    Full Text Available Variability in animal migratory behavior is expected to influence fitness, but few empirical examples demonstrating this relationship exist. The initial marine phase in the migration of juvenile salmon smolts has been identified as a potentially critical life history stage to overall population productivity, yet how fine-scale migration routes may influence survival are unknown. Large-scale acoustic telemetry studies have estimated survival rates of outmigrant Pacific salmon smolts through the Strait of Georgia (SOG along the British Columbian coastline to the Pacific Ocean, but these data have not been used to identify and characterize fine-scale movements. Data collected on over 850 sockeye salmon (Oncorhynchus nerka and steelhead (Oncorhynchus mykiss smolts detected at an array in the Strait of Georgia in 2004-2008 and 2010-2013 were analyzed to characterize migration routes and link movements to subsequent survival at an array 250 km further along the marine migration pathway. Both species exhibited disproportionate use of the most eastern route in the Strait of Georgia (Malaspina Strait. While many smolts moved across the northern Strait of Georgia acoustic array with no indication of long-term milling or large-scale east-to-west movements, large proportions (20-40% of sockeye and 30-50% of steelhead exhibited a different behavior, apparently moving in a westward or counterclockwise pattern. Variability in migratory behavior for both species was linked to subsequent survival through the Strait of Georgia. Survival for both species was influenced by initial east-to-west location, and sockeye were further influenced by migration timing and duration of time spent near the northern Strait of Georgia array. Westward movements result in a net transport of smolts from Malaspina Strait to the Strait of Georgia, particularly for steelhead. Counterclockwise movements may be due to the currents in this area during the time of outmigration, and the

Estudio de tipo descriptivo, transversal, que analiza la morbilidad atendida en consulta externa, hospitalización y urgencias en Colombia durante el quinquenio 2004-2008. MÉTODOS: Se utilizaron los "Registros individuales de prestación de servicios" (RIPS de Colombia, clasificándose los diagnósticos según los grupos de causas definidos por la Organización Mundial de la Salud. Cada grupo de causas para utilización de servicios se discriminó por región geográfica, género y régimen de afiliación al sistema de salud. RESULTADOS: Los diagnósticos de enfermedades transmisibles se encontraron más concentrados en los grupos de edad inferiores, mientras que las no transmisibles fueron más frecuentes en los grupos etarios superiores. Las externalidades (accidentes, lesiones autoinfligidas y violencia fueron una causa importante de morbilidad y afectaron con más fuerza a la población de entre 5 y 44 años de edad. Las patologías transmisibles fueron más prevalentes en mujeres (39,98% que en hombres (28%, en tanto que los hombres se vieron más afectados por las externalidades que las mujeres (18,5 y 7,3%, respectivamente. CONCLUSIONES: Si bien en Colombia han aumentado los diagnósticos de enfermedades no transmisibles, las infecciones siguen teniendo una presencia relevante en todos los grupos de edad y escenarios de prestación de servicios de salud. Tal situación exige revisar las políticas sanitarias para orientarlas no solo a mejorar la salud de la población sino también a reducir la brecha de servicios que existe entre las diferentes regiones del país.

    The assessment of socio-ecological systems can reflect the effects of nature,social economics,and human activities on the ecological environment,which is helpful to understand the context of complex social-ecological systems.Desert areas are ideal for socio-ecological system assessments because the land cover of deserts seriously influences the improvement of the local ecological environment and social economy.Yanchi County in the Ningxia Hui Autonomous Region is a typical desertification area where the ecological environment is very fragile.The government has implemented the Grain for Green Project and a prohibited-grazing policy to suppress and reverse desertification since 2000,and these ecological policies have positive effects on ecological restoration of desert areas.Therefore,it is very important to control desertification and maintain the normal function of local social-ecological systems.In this paper,the social-ecological system disturbance in Yanchi County was analyzed to understand the changes of the local social-ecological system.The MODIS (Moderate resolution Imaging Spectrometer) normalized difference vegetation index (NDVI) data of the study region was applied to investigate the spatial distribution of the existing social-ecological system disturbance during 2000-2015.In addition,moving window computational algorithms were used to calculate social-ecological system disturbance intensity and connectivity at different spatial scales.The results showed that (1) the disturbance had different spatial distributions over different periods,and strong disturbances were mainly distributed in southern Yanchi County during 2000-2004,whereas strong disturbances were distributed in the northern and central areas during 2004-2008.Furthermore,strong disturbances were detected in three small areas:southeastern,central,and western Yanchi County during 2008-2012.Moreover,the proportion of strong disturbances in the North showed an increasing trend.Strong disturbances

    Full Text Available Stachys maritima is a species typical of the coastal dunes, with a wide distribution within the Mediterranean Basin. In spite of this, the species shows a clear regression. In Catalonia, it has been observed an important reduction of its populations since early 20th century, where it has disappeared from several localities in which it was relatively common (Tarragonès, Barcelonès. Herein we present the results of the demographic monitoring of the species during the last 10 years (2001-2010 in the known localities in Catalonia. Besides corroborating the disappearance (northern Sant Martí d’Empúries, the re-discovering (Llobregat Delta beach and the detection of new populations (inner dunes of the Montgrí, a large year-to-year fluctuation of the monitored populations is stated; the possible reasons are discussed. In addition, the present work also includes the results of the allozyme diversity analysis of the new detected populations as well as the rediscoveries of the period 2004-2008, which were not included in a former study of genetic diversity carried out in 2002-2003. It is necessary to emphasize that the contribution of the new populations to the genetic diversity of Stachys maritima is very small, which can be attributed to their limited population size and /or to founder effects. Despite that the species is included in the Annex 2 (“En Perill d’Extinció” within the Catàleg de Flora Amenaçada de Catalunya (Catalogue of Endangered Flora of Catalonia, and some “soft” conservation measures have been applied at local level (signposting of the beach accesses, environmental education, etc. coupled with other more significant measures (e.g. translocation of individuals discovered in an artificial sandbank, it would be necessary the coordinated action and the scientific support of any initiative of conservation that could be carried out.

    Cyclic behaviour on a range of timescales is a well-documented feature of many dome-forming volcanoes. Previous work on Soufrière Hills volcano (Montserrat) and Volcán de Colima (Mexico) revealed broad-scale similarities in behaviour implying the potential to develop general physical models of sub-surface processes [1]. Using volcano-seismic data from Mt St Helens (USA) and Mt Unzen (Japan) this study explores parallels in long-term behaviour of seismicity at two dome-forming systems. Within the last twenty years both systems underwent extended dome-forming episodes accompanied by large Vulcanian explosions or dome collapses. This study uses a suite of quantitative and analytical techniques which can highlight differences or similarities in volcano seismic behaviour, and compare the behaviour to changes in activity during the eruptive episodes. Seismic events were automatically detected and characterized on a single short-period seismometer station located 1.5km from the 2004-2008 vent at Mt St Helens. A total of 714 826 individual events were identified from continuous recording of seismic data from 22 October 2004 to 28 February 2006 (average 60.2 events per hour) using a short-term/long-term average algorithm. An equivalent count will be produced from seismometer recordings over the later stages of the 1991-1995 eruption at MT Unzen. The event count time-series from Mt St Helens is then analysed using Multi-taper Method and the Short-Term Fourier Transform to explore temporal variations in activity. Preliminary analysis of seismicity from Mt St Helens suggests cyclic behaviour of subannual timescale, similar to that described at Volcán de Colima and Soufrière Hills volcano [1]. Frequency Index and waveform correlation tools will be implemented to analyse changes in the frequency content of the seismicity and to explore their relations to different phases of activity at the volcano. A single station approach is used to gain a fine-scale view of variations in

    Objective: To investigate the combined impact of lifestyle factors on stomach cancer risk. Methods: We analyzed the data from the Shanghai Men's Health Study (SMHS) (2002-2013). The SMHS was conducted in eight neighborhood communities of urban Shanghai. From 2002 through June 2006, 61 480 residents aged 40 to 74 years old with no history of cancer were recruited. Failure time was the date of stomach cancer incidence, death or date of the last follow-up (December 31, 2013). The first two in-person follow-up surveys were conducted in 2004-2008, and 2008-2011, respectively. Using data on lifestyle, the healthy lifestyle index (HLI) was developed. The following lifestyle factors were included: smoking, alcohol consumption, diet habit, overweighted and physical activity. Cox proportional hazard models were used to evaluate the association of stomach cancer risk with lifestyle factors and HLI. Results: Over 9.28 years' follow-up, 477 incident cases of stomach cancer were identified from 59 503 study participants. Participants with zero, one, two, three, four, and five favorable lifestyle behaviors accounted for 3.44% ( n= 2 045), 18.14% ( n= 10 793), 33.68% ( n= 20 041), 29.43% ( n= 17 511), 12.82% ( n= 7 627), and 2.50% ( n= 1 486), respectively. Among all the five lifestyle factors, smoking and alcohol use were significantly related to stomach cancer risk. The relative risk of stomach cancer was 0.71 (95 %CI : 0.57-0.87) for those who never smoked or quitted smoking for no less than 10 years and 0.70 (95 %CI : 0.55-0.90) for those who consumed alcohol no more than 14 drinks per week. For each increment of healthy lifestyle index, the relative risk of stomach cancer was 0.86 (95 %CI : 0.79-0.95). Compared to men with none or one healthy lifestyle factor, the relative risk for those with four or five was 0.62 (95 %CI : 0.46-0.83). When we rebuilt HLI using more categories of each lifestyle factors, the HLI ranged from 0 to 11. For each point increase, the relative risk

The forest investigations form a part of the monitoring programme being carried out on Olkiluoto Island under the management of Posiva Oy. This report focuses on activities performed on bulk deposition and forest intensive monitoring plots (MRK and FIP plots) in 2010. In general, the deposition levels in 2010 in the open area and in stand throughfall were quite comparable to those in earlier years, although sulphur and calcium depositions were somewhat higher in the open area than in earlier years (2004-2008). The soil solution quality in 2010 was also quite comparable to that in earlier years. The NH 4 -N and NO 3 -N concentrations were low at all depths in the mineral soil of the FIP plots 4, 10 and 11. Instead, nitrate concentrations were high in the soil solution on FIP14. There appeared to be a clear overall increase in sulphate concentrations with increasing depth on FIP4 and FIP10. Chloride concentrations in the soil solution were extremely high at all depths on all FIP plots throughout the monitoring period; it is clear that there is a considerable input of NaCl in the deposition derived from the sea. The concentrations of heavy metals (Cd, Cr, Ni, Pb) in the soil solution at all depths at Olkiluoto during 2004-2010 continued in many cases to be close to or below the limit of quantification. In 2010 the monthly level of transpiration in the Scots pine dominated stand was smaller in May and bigger in July than during previous years (2007-2009). Monthly transpiration in the Norway spruce dominated stand was clearly lower in 2010 than in 2007-2009, and there is a decreasing

    Full Text Available We present a strategy (MIR-GBM v1.0 for the retrieval of column-averaged dry-air mole fractions of methane (XCH4 with a precision <0.3% (1-σ diurnal variation, 7-min integration and a seasonal bias <0.14% from mid-infrared ground-based solar FTIR measurements of the Network for the Detection of Atmospheric Composition Change (NDACC, comprising 22 FTIR stations. This makes NDACC methane data useful for satellite validation and for the inversion of regional-scale sources and sinks in addition to long-term trend analysis. Such retrievals complement the high accuracy and precision near-infrared observations of the younger Total Carbon Column Observing Network (TCCON with time series dating back 15 years or so before TCCON operations began.

    MIR-GBM v1.0 is using HITRAN 2000 (including the 2001 update release and 3 spectral micro windows (2613.70–2615.40 cm−1, 2835.50–2835.80 cm−1, 2921.00–2921.60 cm−1. A first-order Tikhonov constraint is applied to the state vector given in units of per cent of volume mixing ratio. It is tuned to achieve minimum diurnal variation without damping seasonality. Final quality selection of the retrievals uses a threshold for the goodness of fit (χ2 < 1 as well as for the ratio of root-mean-square spectral noise and information content (<0.15%. Column-averaged dry-air mole fractions are calculated using the retrieved methane profiles and four-times-daily pressure-temperature-humidity profiles from National Center for Environmental Prediction (NCEP interpolated to the time of measurement.

    MIR-GBM v1.0 is the optimum of 24 tested retrieval strategies (8 different spectral micro-window selections, 3 spectroscopic line lists: HITRAN 2000, 2004, 2008. Dominant errors of the non-optimum retrieval strategies are systematic HDO/H2O-CH4 interference errors leading to a seasonal bias up to ≈5%. Therefore interference

    The recovery of young allopatric brown trout (Salmo trutta) grouped into YoY (age 0+) and older parr (age ≥1+) fish, was studied in acid-sensitive streams in a Norwegian watershed during a 24-year-period (1987-2010). Their abundance was assessed by electrofishing. Most sites typically had 5.0-5.5 in pH, 0.4-0.7 mg L-1 Ca, 10-20 μg L-1 inorganic toxic aluminum (Ali) and acid-neutralizing capacity adjusted for organic acids (ANCOAA) of - 15 to +25 μeq L-1. Densities of both YoY and older parr increased significantly during the study period. Water quality also improved in recent years with respect to pH (5.8-6.0), Ali (5-15 μg L-1) and ANCOAA (10-20 μeq L-1). However, some negative trends in both fish density and water chemistry were found during both the first (1987-1993) and last years (2004-2008) of the study. Initially, YoY densities remained at about 16-20 specimens 100 m-2 (1987-1990), declined to 10-15 specimens 100 m-2 in the early/mid 1990s, and rosed to 30-50 specimens 100 m-2 in recent years (1997-2010). Their densities correlated significantly with ANCOAA, and at least three stages in the recovery process were recognised: (i) Low density with 10-20 specimens 100 m-2 at -18 to -5 μeq L-1, (ii) medium and unstable density with 20-30 specimens 100 m-2 at -5 to 10 μeq L-1, and (iii) increasing density to 40-50 specimens 100 m-2 at 10-25 μeq L-1. The decline in brown trout density in the early-mid 1990s coincided with high sea salt depositions, which caused increased acidification. Component 1 in a PCA explained 51% of the variation in fish densities, including conductivity, Mg, Ca, Na, alkalinity and TOC. Component 2 explained an additional 31% of the variation, including pH, Ali and ANCOAA. Multiple regression analysis coefficients showed that the two components explained 41% of the variance in total fish density. Young brown trout suffered a high mortality during the initial phase of the study in spite of relative low levels of Ali. This is

    Changes in municipal and industrial point-source discharges over time have been an important factor affecting nutrient trends in many of the Nation’s streams and rivers. This report documents how three U.S. Environmental Protection Agency (EPA) national datasets—the Permit Compliance System, the Integrated Compliance Information System, and the Clean Watersheds Needs Survey—were evaluated for use in the U.S. Geological Survey National Water-Quality Assessment project to assess the causes of nutrient trends. This report also describes how a database of total nitrogen load and total phosphorous load was generated for select wastewater treatment facilities in the United States based on information reported in the EPA Clean Watersheds Needs Survey. Nutrient loads were calculated for the years 1978, 1980, 1982, 1984, 1986, 1988, 1990, 1992, 1996, 2000, 2004, 2008, and 2012 based on average nitrogen and phosphorous concentrations for reported treatment levels and on annual reported flow values.The EPA Permit Compliance System (PCS) and Integrated Compliance Information System (ICIS), which monitor point-source facility discharges, together are the Nation’s most spatially comprehensive dataset for nutrients released to surface waters. However, datasets for many individual facilities are incomplete, the PCS/ICIS historical data date back only to 1989, and historical data are available for only a limited number of facilities. Additionally, inconsistencies in facility reporting make it difficult to track or identify changes in nutrient discharges over time. Previous efforts made by the U.S. Geological Survey to “fill in” gaps in the PCS/ICIS data were based on statistical methods—missing data were filled in through the use of a statistical model based on the Standard Industrial Classification code, size, and flow class of the facility and on seasonal nutrient discharges of similar facilities. This approach was used to estimate point-source loads for a single

    period of 2003-2010. Ecosystem heterotrophic respiration (RH) was negatively affected by the aerosol loading. These results support previous conclusions of the advantage of aerosol light scattering effect on plant productions in other studies but suggest there is strong spatial variation. This study finds indirect aerosol effects on terrestrial ecosystem carbon dynamics through affecting plant phenology, thermal and hydrological environments. All these evidences suggested that the aerosol direct radiative effect on global terrestrial ecosystem carbon dynamics should be considered to better understand the global carbon cycle and climate change. An ozone sub-model is developed in this dissertation and fully coupled with iTem. The coupled model, named iTemO3 considers the processes of ozone stomatal deposition, plant defense to ozone influx, ozone damage and plant repairing mechanism. By using a global atmospheric chemical transport model (GACTM) estimated ground-level ozone concentration data, the model estimated global annual stomatal ozone deposition is 234.0 Tg O3 yr-1 and indicates which regions have high ozone damage risk. Different plant functional types, sunlit and shaded leaves are shown to have different responses to ozone. The model predictions suggest that ozone has caused considerable change on global terrestrial ecosystem carbon storage and carbon exchanges over the study period 2004-2008. The study suggests that uncertainty of the key parameters in iTemO3 could result in large errors in model predictions. Thus more experimental data for better model parameterization is highly needed.
