    Full Text Available Over diagnosis of acute rheumatic fever (ARF based on a raised antistreptolysin O titer (ASOT is not uncommon in endemic areas. In this study, 660 children (aged 9.2 ±1.7 years were recruited consecutively and classified as: G1 (control group, n=200 healthy children, G2 (n=20 with ARF 1st attack, G3 (n=40 with recurrent ARF, G4 (n=100 with rheumatic heart disease (RHD on long acting penicillin (LAP, G5 (n=100 with acute follicular tonsillitis, and G6 (n=200 healthy children with history of repeated follicular tonsillitis more than three times a year. Serum ASOT was measured by latex agglutination. Upper limit of normal (ULN ASOT (80th percentile was 400 IU in G1, 200 IU in G4, and 1600 IU in G6. Significantly high levels were seen in ARF 1st attack when compared to groups 1 and 5 (P<0.001 and P<0.05, respectively. ASOT was significantly high in children over ten years of age, during winter and in those with acute rheumatic carditis. ASOT showed significant direct correlation with the number of attacks of tonsillitis (P<0.05. Egyptian children have high ULN ASOT reaching 400 IU. This has to be taken into consideration when interpreting its values in suspected ARF. A rise in ASOT is less prominent in recurrent ARF compared to 1st attack, and acute and recurrent tonsillitis. Basal levels of ASOT increase with age but the pattern of increase during infection is not age dependent

  2. Is raised helicobacter pylori antibody titre enough to decide retreatment

    International Nuclear Information System (INIS)

    Background: Helicobacter pylori infection causes a rise in its antibodies which take almost a year to come to baseline following successful eradication treatment. Checking these values in between a year may give falsely high values and many patients may thus be over treated. Aims: To serially determine Helicobacter pylori antibody titres in patients after giving them triple therapy for H. pylori eradication and see how these values drop over time. Study type, Settings and duration: Longitudinal study conducted in Department of Gastroenterology and Hepatology, Pakistan Medical Research Council, Research Centre, Jinnah Post Graduate Medical Centre, Karachi, from May 2006 to April 2010. Subjects and Methods: Over the period of four years, 186 patients who were found positive for campylobacter like organism test during endoscopy were further tested for anti H. pylori IgG titre before being treated for H. pylori. Patients were given triple therapy comprising of Omeprazole (20 mg twice daily), Amoxicillin (1 gm twice daily) and Clarythromycin (500 mg twice daily) for a week and were followed at 1, 3, 6 and 12 months to check symptomatic relief and they were tested again for H.Pylori antibody titres. Data was collected on pre-designed proforma which included patient's demography, symptoms and diagnosis. Results: Out of 186 patients who had a positive campylobacter like organism test, 173 patients consented to participate in the study. Serology for H.Pylori was positive in 119(68%) cases. A decline in mean antibody titres was observed as 11%, 21.5%, 54.7% and 59.2% at 1, 3, 6 and 12 months respectively. Conclusions: Sensitivity of serology for diagnosing H. pylori infection is good but using these as a tool for monitoring response to treatment is doubtful. A slow drop in H.pylori antibodies was seen over 12 months and therefore, physicians are cautioned not to retreat the already treated cases till about one year post treatment. Policy message: H. pylori antibodies should

    A new compact-type latex photometric immunoassay system, SPOTCHEM IM SI-3510 (ARKRAY, Inc., Kyoto, Japan), which assays three kinds of inflammatory markers-neutrophil count (NPC), C-reactive protein (CRP), and anti-streptolysin O (ASO)-was evaluated. Hemoglobin (Hb), which is a good marker for anemia, can also be measured with it. NPC and CRP are measured using antibodies against neutrophilic elastase and CRP, purified streptolysin O was used for ASO determination, and Hb was measured by an azide-methemoglobin method. Whole blood, serum, and plasma specimens can be used as samples with this system. In this study, whole blood treated with dipotassium ethylenediamine tetraacetic acid was used for evaluation. Linearity and reproducibility were good for all of the items studied. Good correlations were observed between the results obtained by this system and those obtained by routine methods. Since NPC exhibited a high correlation with the routine white blood cell (WBC) counts, it was judged to be useful as a substitute for WBC counting. Since this system is small and easy to operate, and evaluation revealed reliable results, it was judged to be practical for small laboratories, and satellite testing in hospitals and physicians' office laboratories for patients suspected to have acute inflammation.

    Objective: To observe the changes and the diagnostic values of anti - Dnase B and Antistreptolysin O in serum of rheumatic disease patients caused by group A streptococcal (GAS) infection. Methods: Thirty patients with acute rheumatic fever (ARF) and 30 patients with Rheumatic activity heart disease and 30 patients with Rheumatic arthritis were included in the present study. Immune scatter nephelometry test was used to detect the level of anti - Dnase B and ASO in serum. Results: The positive rates of ASO in patients with ARF, Rheumatic activity heart disease and Rheumatic arthritis were 80%, 57.3% and 53.3%, respectively. The positive rates of anti -Dnase B in patients with ARF, Rheumatic activity heart disease and Rheumatic arthritis were 70%, 85.7% and 60%, respectively. Other than the group of Rheumatic activity heart disease, there was no statistical difference between the positive rates of ASO and anti - Dnase B in patients with ARF and Rheumatic arthritis. The positive rates of the joint detection of anti - Dnase B and ASO in patients with ARF, Rheumatic activity heart disease and Rheumatic arthritis were 90%, 92.8% and 80%, respectively. There was statistically significant difference in the positive rate between joint detection and any single test. Conclusion: The joint detection of anti - Dnase B and ASO could improve the diagnosis of Rheumatic disease and should be of important clinical value in the diagnosis of rheumatic disease.%目的:研究溶血性链球菌感染引起的风湿病患者抗DNA酶B和ASO的血清学变化及意义.方法:收集30例急性风湿热、30例活动期风湿性心脏病、30例风湿性关节炎患者血清,免疫散射比浊法检测其抗DNA酶B和ASO水平.结果:三组患者的ASO阳性率分别为80%、57.3%、53.3%,抗DNA酶B检测阳性率分别为70%、85.7%、60%.除活动期风湿性心脏病组外,其余两组患者的ASO阳性率与抗DNA酶B检测阳性率间的差异无统计学意义(P>0.05).

    Full Text Available The aim of this study was to define an estimated antibody titre which was considered to be protective against Newcastle disease (ND virus infection in ostriches. Eighteen young ostriches of 4 days of age were divided into two groups each containing 9 birds. The first group was unvaccinated and the second group was vaccinated against ND virus twice at 4 and 14 days of age. Antibody titres were monitored at 1, 14, 28, 42, 56, 70 and 85 days of age by haemagglutination inhibition (HI test. All birds were then challenged with a velogenic strain of ND virus, Ita strain, at 42 days of age. The excretion of the challenge virus were monitored daily after challenge up to the end of this experiment. Several organs such as brain, trachea, lungs and spleen were collected from died birds for re-isolation of the challenged virus. Results indicated that all unvaccinated birds succumbed to the challenged virus, except one bird that survived challenged. In contrast to the unvaccinated birds, all vaccinated birds survived challenged, except two birds with low antibody titres succumbed challenged. All birds with antibody titres of 4 (HI-log2 or greater survived challenged. All challenged birds excreted the challenged virus through out their oropharyngs. Moreover, challenged virus can be successfully re-isolated from most organs of the died birds. This study concludes that : (a the estimated protective titre against ND in ostriches is 4 (HI-log2, (b the immune status for ostrich with antibody titre less the 4 (HI-log2 could not be defined, and (c vaccination against Newcastle disease in ostriches could successfully prevent birds from sick and died of ND, but unable to prevent virus infection and unable to stop carrier status after infection.

Quelle que soit leur valeur précise, ces titres permettent de revisiter un problème maintes fois soulevé par les musicologues et les sémioticiens: celui de savoir si la musique « réfère », et à quoi. Dans le cas des disques Blue Note, la question se pose d’une manière particulièrement aiguë à propos de certains enregistrements des années 1960, dont les titres (It’s Time, Right Now, Let Freedom Ring, etc. peuvent référer aux structures du jazz ou à la situation des noirs dans la société américaine, qu’il s’agit tous deux de transformer dans le sens d’une liberté accrue.The titles on the jackets of the records of the label Blue Note can denote the musical content of the album (Boogie-Woogie Classics, connote it (Blue Hour, or function strictly as indexes (Speak No Evil. Whatever their exact value might be, those titles make it possible to revisit a problem frequently raised in semiotics and musicology: the problem of knowing whether music « refers », and to what exactly. The question is especially acute in the case of some of the records released by Blue Note in the1960s, whose titles (It’s Time, Right Now, Let Freedom Ring may refer to musical structures or to the situation of African-Americans in American sociey, which have both to be changed in the sense of more freedom.

    Full Text Available A total of 200 chicks were raised upto 43 days of age under controlled experimental conditions. The birds were randomly divided into four groups A, B, C and D of 50 birds each at the age of day one. Birds of groups A and B were not supplemented with selenium, while those of groups C and D were given selenium @ 0.06 mg/Kg of feed from day one to day 43. The birds of groups B and D were vaccinated against infectious bursal disease (IBD at the age of day 10 and boosted at the age of day 25. The effect of selenium on humoral immune response was evaluated by recording weekly serum antibody titres against IBD through indirect haemagglutination (IHA test. The cumulative mean titres (CMT recorded in groups A, B, C and D were 15, 53, 16 and 61, respectively (P<0.05. These results indicate that selenium supplementation may help to increase post vaccination humoral immune response against IBD in broiler chicks.

    Effective gene therapy for haemophilia A necessitates a vector system that is not subject to a pre-existing immune response, has adequate coding capacity, gives long-term expression and preferably can target non-dividing cells. Vector systems based on lentiviruses such as equine infectious anaemia virus (EIAV) fulfil these criteria for the delivery of factor VIII (FVIII). We have found that B domain-deleted (BDD) FVIII protein inhibits functional viral particle production when co-expressed with the EIAV vector system. Although particle numbers (as measured by reverse transcriptase activity) are near normal, RNA genome levels are reduced and measurement of integrated copies revealed the virus is severely defective in its ability to transduce target cells. This is due to the absence of sufficient vesicular stomatitis virus glycoprotein (VSV-G) envelope on viral particles derived from cells expressing FVIII. By using an internal tissue-specific promoter, that has low activity in the producer cells, to drive expression of FVIII we have overcome this inhibitory effect allowing us to generate titres approaching those obtained with vector genomes encoding reporter genes. Furthermore, we report that codon optimization of the full-length FVIII gene increased vector titres approximately 10-fold in addition to substantially improving expression per integrated vector copy.

    A retrospective study was performed to determine if there is an association between serological Coccidioides immitis antibody titres (IgG) and form/severity of coccidioidal disease in horses, and to identify trends in survival and treatment success based on the form of the disease. Data were obtained on horses with positive serological titres tested at the Coccidioidomycosis Serology Laboratory, School of Medicine, University of California, Davis from 1981 to 2004. Thirty-nine cases in which a diagnosis of coccidioidomycosis had been made were selected for inclusion. Six distinct categories were identified including abortion (n=6), miliary/interstitial pneumonia (n=6), pneumonia with thoracic effusion (pleural or pericardial) (n=11), disseminated (n=10), osteomyelitis (n=3) and external abscessation (n=3) both without pulmonary disease. Statistical differences in titre distribution were found between the abortion category and the pulmonary category (P=0.003), the abortion category and pneumonia with thoracic effusion (P=0.001), the abortion category and disseminated disease (P=0.001), and the pulmonary form and pneumonia with effusion (P=0.001). The other categories had overlapping titre results. Higher serological antibody titres seemed to be associated with a poorer prognosis for survival. Categories with the highest titres, disseminated (geometric mean titre=104) and pneumonia with thoracic effusion (geometric mean titre=226), were overwhelmingly fatal (19/21 known deaths) due to severe clinical disease. The categories with lower titres, abortion (geometric mean titre=4), bone involvement only (geometric mean titre=13) and cutaneous (geometric mean titre=5), had a better survival rate (10/12 known survivors) and less severe clinical disease. Measurement of serological titre may be a useful diagnostic aid in establishing form and severity of disease and thus inform prognosis. PMID:16249106

    After a single injection of purified Vi polysaccharide vaccine against typhoid fever, serum titres were followed in student volunteers by passive haemagglutination assay and by radioimmunoassay. Elevated Vi antibody titres were still present after 36 months. This preliminary study should be followed by further investigations on the extent and duration of protection provided by Vi vaccine, and on volunteers in endemic areas.

    Most influenza virus infections are associated with mild disease. One approach to estimate the occurrence of influenza virus infections in individuals is via repeated measurement of humoral antibody titres. We used baseline and convalescent antibody titres measured by haemagglutination inhibition (HI) and viral neutralization (VN) assays against influenza A(H1N1), A(H3N2) and B viruses to investigate the characteristics of antibody rises following virologically confirmed influenza virus infections in participants in a community-based study. Multivariate models were fitted in a Bayesian framework to characterize the distribution of changes in antibody titres following influenza A virus infections. In 122 participants with PCR-confirmed influenza A virus infection, homologous antibody titres rose by geometric means of 1·2- to 10·2-fold after infection with A(H1N1), A(H3N2) and A(H1N1)pdm09. Significant cross-reactions were observed between A(H1N1)pdm09 and seasonal A(H1N1). Antibody titre rises for some subtypes and assays varied by age, receipt of oseltamivir treatment, and recent receipt of influenza vaccination. In conclusion, we provided a quantitative description of the mean and variation in rises in influenza virus antibody titres following influenza virus infection. The multivariate patterns in boosting of antibody titres following influenza virus infection could be taken into account to improve estimates of cumulative incidence of infection in seroepidemiological studies.

    Full Text Available Introduction: The interpretation of Widal test depends upon the baseline titre which is prevalent amongst healthy individuals in a particular geographical area. Aim and Objective: The aim of this study was to determine the baseline Widal titre of the apparently healthy population of a tertiary care centre of Uttarakhand. Material and Methods: Blood samples were collected from healthy blood donors (n=500 of the age group of 18-60 years, of both the sexes, who attended our blood bank from September 2013 to November 2013 and were analyzed for the presence of Salmonella antibodies by carrying out the Widal tube agglutination test. Results: Of the 500 serum samples which were tested, 255 (51% serum samples were positive for agglutinins (≥ 1:20 and 245 were negative. The most frequently recorded titre of the reactive sera was 1:40 for the anti-O antibodies and 1:80 for the anti-H antibodies for Salmonella enterica serotype typhi and this was the baseline titre. While the baseline titre of the ‘H’ agglutinins of Salmonella enterica serotype paratyphi A was 1:20 and of paratyphi B was also1:20. Conclusions: Based on the results of our study, it has been recommended that the significant titre of 1:80 for the anti-O antibodies and of 1:160 for the anti-H antibodies may be considered as diagnostic for enteric fever in the region of Uttarakhand, India.

    Intrauterine blood transfusion is the mainstay of managing foetuses with severe anemia. It may however result in fetomaternal hemorrhage, which in cases of Rh isoimmunisation may increase the severity of the disease by enhancing the maternal immunological response to fetal antigens. This study was conducted to determine the frequency, specificity and origin of additional red cell antibodies which developed after IUT. The change in the titre of allo anti-D following IUT was also determined. Antibody detection and titration was done on the blood samples of all the patients before and after intrauterine blood transfusion to check for the development of additional antibody and change in the titre of existing anti-D. Severe anemia was found in 17 (58.6 %) fetuses who received a total of 42 ultrasound-guided IUTs. Development of antibodies additional to anti-D in maternal serum was seen in 5 (29.4 %) cases. The specificity of additional alloantibodies was anti-C in four cases whereas it was anti-E in one case. Four fold or greater increase in existing allo-anti D titre was seen in 6 (35.3 %) cases after IUT. Enhancement of maternal sensitisation leading to an increase in maternal antibody titre is particularly seen after the first IUT. Matching of the donor RBCs particularly for Rh antigens might prevent the induction of additional alloantibodies against these antigens. IUT as a treatment modality should be given judiciously and only when the need is inevitable. PMID:26855513

    In contrast to many regions of the world where rabies is endemic in terrestrial wildlife species, wildlife rabies has been controlled in Israel by oral rabies vaccination programs, but canine rabies is re-emerging in the northern area of the Golan Heights. From 2009 to 2014 there were 208 animal rabies cases in Israel; 96 (46%) were considered introduced primary cases in dogs, triggering 112 secondary cases. One third (37/112) of the secondary cases were in cattle. Rabies vaccination is voluntary for cattle in Israel, except those on public exhibit. Rabies vaccination schedules for cattle vary based on farm practices and perception of risk. In this study 59 cattle from a dairy farm which routinely vaccinates against rabies were assigned into six groups according to age and vaccination histories. Four groups contained adult cows which had received one previous rabies vaccination, one group of adults had received two previous vaccinations, and one group was unvaccinated calves. Serum samples were collected and the cows were vaccinated with a commercial rabies vaccine. Sera were again collected 39 days later and the calf group re-vaccinated and re-sampled 18 days later. Sera were analyzed for the presence of rabies virus neutralizing antibodies using the rapid immunofluorescent antibody test. Cattle with antibody titres ≥ 0.5 IU/ml were considered to be protected against rabies. Twenty-six of 27 adult cattle (96%) vaccinated once at less than five months old did not have protective titres. Sixty percent (6/10) cattle vaccinated once at around six months of age did have adequate titres. Cattle previously vaccinated twice (n=10; 100%) with an 18 month interval between inoculations, had protective titres and protective antibody titres following booster vaccination (n=51; 100%). The anamnestic response of cattle to a killed rabies vaccine was not affected by the time interval between vaccinations, which ranged from 12 to 36 months. These results suggest that calves from

    A solid-phase radioimmunoassay for the measurement of circulating antibody titres to wheat gliadin is described. Using this assay, the authors have measured antibody titres to unfractionated gliadin in normal healthy controls, in coeliac patients on a gluten-free or a normal diet, and in patients with ulcerative colitis and Crohn's disease. High titres of antibodies to unfractionated gliadin were observed only in the patients with untreated coeliac disease. Antibody titres to ..cap alpha.., ..beta.., ..gamma.. and ..omega.. gliadin subfractions were measured in patients with untreated coeliac disease and compared with titres in normal controls. Patients with untreated coeliac disease had higher antibody titres to the gliadin subfractions. No specific pattern of circulating antibody titres to gliadin subfractions was observed in the untreated coeliac patients which would provide a diagnostic profile. These results suggest shared antigenicity between the gliadin subfractions.

    Lentiviruses are the vectors of choice for many preclinical studies and clinical applications of gene therapy. Accurate measurement of biological vector titre before treatment is a prerequisite for vector dosing, and the calculation of vector integration sites per cell after treatment is as critical to the characterisation of modified cell products as it is to long-term follow-up and the assessment of risk and therapeutic efficiency in patients. These analyses are typically based on quantitative real-time PCR (qPCR), but as yet compromise accuracy and comparability between laboratories and experimental systems, the former by using separate simplex reactions for the detection of endogene and lentiviral sequences and the latter by designing different PCR assays for analyses in human cells and animal disease models. In this study, we validate in human and murine cells a qPCR system for the single-tube assessment of lentiviral vector copy numbers that is suitable for analyses in at least 33 different mammalian species, including human and other primates, mouse, pig, cat and domestic ruminants. The established assay combines the accuracy of single-tube quantitation by duplex qPCR with the convenience of one-off assay optimisation for cross-species analyses and with the direct comparability of lentiviral transduction efficiencies in different species.

    Full Text Available Leiomyosarcoma Rhesus (Rh isoimmunization is the development of maternal IgG antibodies against fetal Rh Red Blood Cell (RBC antigens. Transplacental passage of maternal Rh antibody (IgG anti-D may result in Hemolytic Disease of the Newborn (HDN, a condition characterized by hemolysis, severe fetal anemia and generalized fetal edema (hydrops fetalis. The severity of Rh hemolytic disease may be assessed in the Immunized patient by several different means which include: past obstetric history, maternal antibody titer, ultrasonography, amniotic fluid bilirubin quantification, and percutaneous umbilical blood sampling. A past history of fetal demise, hydrops fetalis, intrauterine transfusion or neonatal exchange transfusion implies that the present pregnancy is or will be severely affected because Rh disease effects on the fetus generally recur or present progressively earlier or more severely with each successive Rh positive pregnancy. We present here a rare case of Rh sensitized pregnancy with high ICT titre who had normal fetal outcome. [Int J Reprod Contracept Obstet Gynecol 2015; 4(5.000: 1574-1576

    Full Text Available In this paper, the antibody titre to Salmonella enteritidis (SE was examined by the ELISA method in two flocks of laying hens, where during routine bacteriological investigations Salmonellae was never isolated, and in one flock where Colysepticemia was diagnosed and Salmonella isolated accidentally. In the flocks were Salmonellae were not isolated, a titre with a high level of specific antibodies to SE was discovered (15 and 45%, while the flock with accidental findings of SE was poorly positive (5%. These results point to the necessity of introducing serological monitoring to SE so that the infection of salmonella may be discovered early and the prevalence in the flock determined, and also for the purpose of applying adequate measures that could reduce the possibility of secretion of SE through eggs.

    The treponemal haemagglutination (THA) test has been used for 11 years as a routine test for syphilis at a central serology laboratory. Among patients with untreated early syphilis the antibodies detected by the THA test usually appeared later or were of relatively lower titre than those detected by the reagin tests. This finding was confirmed by follow up of patients and by replies to questionnaires and has been incorporated in a computer program. During 1981, using the results obtained on u...

    Full Text Available Background: Adhesion can actually be considered as a part of both a powerful survival mechanism and a virulence mechanism for bacterial pathogens. Bacterial adhesin is an instrument for bacteria to do invasion to host. Bacterial adhesin depends on ligand interaction as a signaling mediator that will influence invasion and increase pro and anti-inflammatory because of the influence of the receptors of innate immune response. Aggregatibacter actimycetemcomitans has fimbriae included in type IV pili containing mostly with protein weighed 6.5 kDa and at least with protein weighed 54 kDa. Purpose: The purpose of this research is to analyze the influence of the induction of adhesin protein derived from A. actinomycetemcomitans on IL-8 and MMP-8 titre of Wistar rats. Methods: Adhesin protein derived from A. actinomycetemcomitans weighed 24 kDa was induced on the maxillary first molar sulcus of Wistar rats to prove that adhesin protein could affect IL-8 and MMP-8 titre. Next, to determine its influence, Elisa technique was conducted. Results: It is known that the levels of IL-8 and MMP-8 titre were increased in the group induced with adhesin protein derived from A. actinomycetemcomitans compared with the control group. Conclusion: It can be concluded that adhesin protein derived from A. actinomycetemcomitans can cause alveolar bone damage through the increasing levels of IL-8 and MMP-8 in aggressive periodontitis.

    Full Text Available Abstract Background Antibodies directed against haemagglutinin, measured by the haemagglutination inhibition (HI assay are essential to protective immunity against influenza infection. An HI titre of 1:40 is generally accepted to correspond to a 50% reduction in the risk of contracting influenza in a susceptible population, but limited attempts have been made to further quantify the association between HI titre and protective efficacy. Methods We present a model, using a meta-analytical approach, that estimates the level of clinical protection against influenza at any HI titre level. Source data were derived from a systematic literature review that identified 15 studies, representing a total of 5899 adult subjects and 1304 influenza cases with interval-censored information on HI titre. The parameters of the relationship between HI titre and clinical protection were estimated using Bayesian inference with a consideration of random effects and censorship in the available information. Results A significant and positive relationship between HI titre and clinical protection against influenza was observed in all tested models. This relationship was found to be similar irrespective of the type of viral strain (A or B and the vaccination status of the individuals. Conclusion Although limitations in the data used should not be overlooked, the relationship derived in this analysis provides a means to predict the efficacy of inactivated influenza vaccines when only immunogenicity data are available. This relationship can also be useful for comparing the efficacy of different influenza vaccines based on their immunological profile.

  13. The role of antibody affinity and titre in immunity to Schistosoma mansoni following vaccination with highly irradiated cercariae

    1990-02-01

    Sera from rabbits and rats vaccinated with highly irradiated cercariae of Schistosoma mansoni (VRabS, VRatS) were found to be of substantially higher affinity than sera from CBA mice vaccinated four times (4 x CVMS), single sex sera (SSS) or chronic infection sera (CIS). In contrast, immunoprecipitation studies demonstrated that sera from vaccinated LA mice (LVMS) recognized {sup 125}I-labelled schistosomular surface antigens more intensely than sera from vaccinated HA mice (HVMS). However, peritoneal macrophages from HA and LA mice in the presence of HVMS, LVMS or 4 x CVMS, and naive macrophages activated in vitro with interferon-gamma (IFN-{gamma})/lipopolysaccharide (LPS) mediated comparable levels of schistosomula killing in vitro. The experiments described here provide evidence that the titre of antibody rather than its affinity may be a more critical factor in the development of optimal immunity to S. mansoni. (author).

This is especially true in the postmenopausal state, where lipid profiles and CHD risk mimic that of age-matched men. Thus, interventions designed to reduce CHD risk by raising HDL-C levels may have particular significance during the transition to menopause. This review discusses HDL-C-raising therapies and the role of HDL in the primary prevention of CHD in women. Lifestyle-based interventions such as dietary change, aerobic exercise regimens, and smoking cessation are initial steps that are effective in raising HDL-C, and available data suggest women respond similarly to men with these interventions. When combined with pharmacotherapy, the effects of these lifestyle alterations are further amplified. Though studies demonstrating gender-specific differences in therapy are limited, niacin continues to be the most effective agent in raising HDL-C levels, especially when used in combination with fibrate or statin therapy. Emerging treatments such as HDL mimetic therapy show much promise in further raising HDL-C levels and improving cardiovascular outcomes.Keywords: high-density lipoprotein, HDL, women, cholesterol, heart disease

    This study investigated the conversion of Lemna minor biomass to bioethanol. The biomass was pre-treated by steam explosion (SE, 210°C, 10 min) and then subjected to simultaneous saccharification and fermentation (SSF) using Cellic® CTec 2 (20 U or 0.87 FPU g(-1) substrate) cellulase plus β-glucosidase (2 U g(-1) substrate) and a yeast inoculum of 10% (v/v or 8.0×10(7) cells mL(-1)). At a substrate concentration of 1% (w/v) an ethanol yield of 80% (w/w, theoretical) was achieved. However at a substrate concentration of 20% (w/v), the ethanol yield was lowered to 18.8% (w/w, theoretical). Yields were considerably improved by increasing the yeast titre in the inoculum or preconditioning the yeast on steam exploded liquor. These approaches enhanced the ethanol yield up to 70% (w/w, theoretical) at a substrate concentration of 20% (w/v) by metabolising fermentation inhibitors. PMID:26210138

  19. Prion subcellular fractionation reveals infectivity spectrum, with a high titre-low PrPres level disparity

    Directory of Open Access Journals (Sweden)

    2012-04-01

    Full Text Available Abstract Background Prion disease transmission and pathogenesis are linked to misfolded, typically protease resistant (PrPres conformers of the normal cellular prion protein (PrPC, with the former posited to be the principal constituent of the infectious 'prion'. Unexplained discrepancies observed between detectable PrPres and infectivity levels exemplify the complexity in deciphering the exact biophysical nature of prions and those host cell factors, if any, which contribute to transmission efficiency. In order to improve our understanding of these important issues, this study utilized a bioassay validated cell culture model of prion infection to investigate discordance between PrPres levels and infectivity titres at a subcellular resolution. Findings Subcellular fractions enriched in lipid rafts or endoplasmic reticulum/mitochondrial marker proteins were equally highly efficient at prion transmission, despite lipid raft fractions containing up to eight times the levels of detectable PrPres. Brain homogenate infectivity was not differentially enhanced by subcellular fraction-specific co-factors, and proteinase K pre-treatment of selected fractions modestly, but equally reduced infectivity. Only lipid raft associated infectivity was enhanced by sonication. Conclusions This study authenticates a subcellular disparity in PrPres and infectivity levels, and eliminates simultaneous divergence of prion strains as the explanation for this phenomenon. On balance, the results align best with the concept that transmission efficiency is influenced more by intrinsic characteristics of the infectious prion, rather than cellular microenvironment conditions or absolute PrPres levels.

RESULTADOS: os títulos de ASO na fase aguda da FRA apresentaram elevação significante até o intervalo de 2- 4 meses (p 960 UI/ml. CONCLUSÃO: esta reavaliação do perfil da ASO indicou uma resposta exuberante na fase aguda da febre reumática indicou ainda que os seus níveis séricos podem diferenciá-la de outras afecções que também cursam com níveis elevados de ASO, como as infecções orofaringeanas recorrentes ou as artrites idiopáticas juvenis em atividade.OBJECTIVE: to determine ASO titer profile by establishing ARF differential diagnoses of other diseases with high levels of ASO antibodies. METHODS: we investigated 78 patients with ARF at onset and follow-up, 22 with isolated chorea at onset, 45 with recurrent oropharyngeal tonsillitis, and 23 with recent flare of juvenile idiopathic arthritis. We tested ASO with automated particle-enhanced immunonephelometric assay (Behring®-Germany. The ASO (IU/ml titers were assessed at the following time intervals: 0-7 days, 1-2 weeks, 2-4 weeks, 1-2 months, 2-4 months, 4-6 months, 6-12 months, 1-2 years, 2-3 years, 3-4 years, and 4-5 years after onset of ARF. RESULTS: ASO titers in patients diagnosed with ARF had a significant increase up to the 2-4-month time interval (P < 0.0001. Baseline levels were observed afterwards in patients under regular penicillin prophylaxis. The levels of ASO in ARF were also significantly higher than in patients with isolated chorea, recurrent oropharyngeal infections or juvenile idiopathic arthritis (P = 0.0025, when age-matched samples of these groups were compared. The test’s sensitivity was 73.3% and the specificity was 57.6%, and it was calculated taking into account the upper limit of normality at 320 IU/ml, as well as the established diagnosis of ARF. The test’s specificity and positive predictive value increased with rising or higher titers, being higher with titers above 960 UI/ml. CONCLUSION: this reappraisal of ASO profile in ARF patients indicates a remarkable response during the acute phase, and that points to the extent to which ASO levels may differentiate ARF from other diseases with high levels of ASO antibodies, as coincidental but unrelated streptococcal infection or chronic arthritis flareup.

  19. Haematopoietic depletion in vaccine-induced neonatal pancytopenia depends on both the titre and specificity of alloantibody and levels of MHC I expression.

    Bell, Charlotte R; MacHugh, Niall D; Connelley, Timothy K; Degnan, Kathryn; Morrison, W Ivan

    2015-07-01

    Bovine Neonatal Pancytopenia (BNP) is a disease of calves characterised by haematopoietic depletion, mediated by ingestion of alloantibodies in colostrum. It has been linked epidemiologically to vaccination of the dams of affected calves with a particular vaccine (Pregsure) containing a novel adjuvant. Evidence suggests that BNP-alloantibodies are directed against MHC I molecules, induced by contaminant bovine cellular material from Madin-Darby Bovine Kidney (MDBK) cells used in the vaccine's production. We aimed to investigate the specificity of BNP-alloantibody for bovine MHC I alleles, particularly those expressed by MDBK cells, and whether depletion of particular cell types is due to differential MHC I expression levels. A complement-mediated cytotoxicity assay was used to assess functional serum alloantibody titres in BNP-dams, Pregsure-vaccinated dams with healthy calves, cows vaccinated with an alternative product and unvaccinated controls. Alloantibody specificity was investigated using transfected mouse lines expressing the individual MHC I alleles identified from MDBK cells and MHC I-defined bovine leukocyte lines. All BNP-dams and 50% of Pregsure-vaccinated cows were shown to have MDBK-MHC I specific alloantibodies, which cross-reacted to varying degrees with other MHC I genotypes. MHC I expression levels on different blood cell types, assessed by flow cytometry, were found to correlate with levels of alloantibody-mediated damage in vitro and in vivo. Alloantibody-killed bone marrow cells were shown to express higher levels of MHC I than undamaged cells. The results provide evidence that MHC I-specific alloantibodies play a dominant role in the pathogenesis of BNP. Haematopoietic depletion was shown to be dependent on the titre and specificity of alloantibody produced by individual cows and the density of surface MHC I expression by different cell types. Collectively, the results support the hypothesis that MHC I molecules originating from MDBK cells

    Raising venture capital (VC) is both an art and a science. Future entrepreneurs should carefully consider the various issues of VC financing that have a strong impact on the success of their business. In addition to attracting the best venture capital firms, these issues include such subtle but important points as the timing of financing (especially of the first round), external support sources, desirable qualities of a VC firm, amount to be raised, establishing a productive interface between the founders and the venture capitalists, and most importantly the effects of well-executed VC funding on hiring senior executives and scientific leaders.

    2008-07-01

    Full Text Available Background: Cholera, an infectious disease caused by Vibrio cholerae, is primarily transmitted by ingestion of contaminated food or water. In severe cases, cholera may lead to severe dehydration, metabolic acidosis, and ultimately, hypovolemic shock and death. Methods: In this study V.cholerae non-O1 was cultured in suitable media. LPS was extracted from the surface of  bacteria by hot phenol-water method and then purified by high-speed centrifugation. For production of specific antibody against LPS, white newzeland rabbits were first immunized by whole cell bacteria and then immunized with highly purified LPS. The titre of the antiserum was determined by ELISA for each serogroup. Results: Results presented in this study indicate that serum anti-LPS antibodies raised against purified LPS of V.cholerae non-O1 can detect V.cholerae non-O1 .Conclusion: This antibody had low cross reactivity with V.cholerae O1, serotype Inaba or Ogawa. So, this antibody can be used for for detection of V. cholerae non-O1.

    Background The relationship between cell-bound complement activation products (CB-CAPs: EC4d, EC3d), anti-C1q, soluble complement C3/C4 and disease activity in systemic lupus erythematosus (SLE) was evaluated. Methods Per protocol, at baseline all SLE subjects enrolled in this longitudinal study presented with active disease and elevated CB-CAPs. At each monthly visit, the non-serological (ns) Safety of Estrogens in Lupus Erythematosus: National Assessment (SELENA-SLEDAI) and the British Isles Lupus Assessment Group (BILAG)-2004 index scores were determined as was a random urinary protein to creatinine ratio (uPCR). Short-form 36 (SF-36) questionnaires were also collected. All soluble markers were determined using immunoassays, while EC4d and EC3d were determined using flow cytometry. Statistical analysis consisted of linear mixed models with random intercept and fixed slopes. Results A total of 36 SLE subjects (mean age 34 years; 94% female) were enrolled and evaluated monthly for an average 11 visits per subject. Clinical improvements were observed during the study, with significant decreases in ns-SELENA-SLEDAI scores, BILAG-2004 index scores and uPCR, and increases in all domains of SF-36 (p<0.01). The longitudinal decrease in ns-SELENA-SLEDAI and BILAG-2004 index scores was significantly associated with reduced EC4d and EC3d levels, reduced anti-C1q titres and increased serum complement C3/C4 (p<0.05). The changes in uPCR significantly correlated with C3, C4, anti-C1q and EC4d, with EC4d outperforming C3/C4 by a multivariate analysis. The reduced EC4d or EC3d was associated with improvements in at least six out of the eight domains of SF-36 and outperformed C3/C4. Anti-dsDNA titres did not correlate with changes in disease activity. Conclusions These data indicate that CB-CAPs and anti-C1q are helpful in monitoring patients with SLE. PMID:27752336

    The present study describes the effects of sow and/or piglet porcine circovirus type 2 (PCV2) vaccination on viraemia, antibody response and production parameters (average daily weight gain [ADWG] and mortality) of piglets from a PCV2 subclinically infected farm. Four hundred seventy-six piglets born from vaccinated (V) or non-vaccinated (NV) sows were further subdivided in a total of four groups: NV sows-NV pigs (NV-NV, n=134), NV sows-V pigs (NV-V, n=135);V sows-NV pigs (V-NV, n=104) and V sows-V pigs (V-V, n=103). A single vaccination of sows before mating was able to confer significantly higher antibody titres to their piglets at 4 weeks of age and a different PCV2 dynamics infection compared to piglets coming from NV sows. Piglet vaccination (independently of sow treatment) caused an earlier seroconversion and lower percentages of PCV2 infected pigs compared to the NV ones throughout their life. The double PCV2 vaccination strategy was able to reduce PCV2 infection but apparently caused some interference in piglet humoral response development. PCV2 vaccination was able to overcome this interference since the ADWG was improved in both groups of vaccinated piglets, independently of the sow treatment, being the highest ones obtained in the double vaccination group.

Fund-raising is, also, an increasingly important part of religious organizations life. Almost each of them engages in some kind of fund-raising activity, with the purpose of generating income to sustain the organization’s programs and activities. The present study analyzes the relationship between religious organizations and fund-raising activities: a correlation that always existed, but now calls for consolidation and improvement in order to allow religious organizations to achieve economic sustainability. Therefore, religious organizations should develop competency and capacity to design and implement fund-raising activities, through appropriate policies, tools and methodologies. In this perspective, the author examines all the facets of fund-raising activities related to the religious organizations sector and, more in general, the possible applications of business administration principles to the management of religious bodies (so-called “church management”.Parole chiave: enti religiosi; fund raising; sostenibilità economica; management

    Science.gov (United States)

    Hadfield, Jessica C

    2014-04-01

    Around the world, an increasing number of grandparents are raising grandchildren in households without a biological parent. This is no less true in the United States, where grandparents raising grandchildren are at increased risk for depression and declining physical health. The purpose of this article is to explore the recent literature as it relates to the psychological and/or physical health of grandparents raising grandchildren. On reviewing 19 articles from the past 10 years, it is clear that the literature consistently verifies the health risks, especially depression, for grandparents raising grandchildren; however, the lack of research regarding grandfathers and non-African American caregivers is apparent. The factors influencing grandparents raising grandchildren are numerous, which calls for care providers to assess the needs, situations, and perceptions of grandparents individually. Finally, a need has arisen for more research suggesting and validating interventions that health care providers can use to support this population of older adults. PMID:24568146

  18. Vowel Raising in Nkpor Dialect: A Pattern of Sound Change

    Directory of Open Access Journals (Sweden)

    Mbah, Evelyn Ezinwanne

    2013-01-01

    Full Text Available This paper explores a pattern of phonological change known as vowel raising in the Nkpor dialect of the Igbo language. Using a corpus of conversational Nkpor speech collected from the respondents through tape-recording, we presented data from an authority analysis of the vowels and auditory data of vowel raising. The data support three main claims. First, the voiced palatal nasal /ɲ/ is elided. It claims that in a word consisting of two root verbs, the initial verb root contains any consonant and any vowel, and the second verb root contains the voiced palatal nasal /ɲ/ and a mid front vowel /e/, then, the voiced palatal nasal is elided. Second, after the elision, the mid vowel /e/ of the second verb is raised to a high front vowel /i/ or /ɪ/, agreeing with the vowel harmony rule. Third, Nkpor dialect goes beyond the raising of only vowels of the second verb. It further raises vowels of the first verb which are not high. The much more rapid loss of the voiced palatal nasal /ɲ/ and the consequent raising of the vowels are plausibly attributed to rapid speech, especially in construction and some sociolinguistic factors.

  19. Raising awareness of climate change: Experience in Lithuania

    Energy Technology Data Exchange (ETDEWEB)

    Bukantis, A.; Kliucininkas, L.; Rimkus, E.; Talockaite, E.

    2007-07-01

    Climate change is getting increased political attention all over the world. Academic research and studies, as well as formal and informal education are prominent participants in the public debate on climate change. Results of the public opinion poll show that although most people in Lithuania are aware of climate change and its threats, additional reliable information is highly required. Awareness-raising activities on climate change issues are foreseen in several national strategic documents. However, awareness-raising activities implemented in Lithuania in recent years could be considered to be isolated instances with a lack of monitoring of implementation and achieved results, lessons learnt, as well as a lack of continuity and coordination between different activities. New awareness-raising methods have to be created and used in order to attract as many target groups as possible. This chapter gives an overview of the main outcomes of the survey of public opinion on climate change issues in Lithuania. Recommendations for awareness-raising in different target groups, as well as several good examples of awareness raising on climate change in engineering studies and activities carried out by non-governmental organizations are presented.

  20. Raised intracranial pressure in Crouzon syndrome: incidence, causes, and management.

    Science.gov (United States)

    Abu-Sittah, Ghassan S; Jeelani, Owase; Dunaway, David; Hayward, Richard

    2016-04-01

    OBJECT Patients with Crouzon syndrome (CS) are at risk for developing raised intracranial pressure (ICP), which has the potential to impair both vision and neurocognitive development. For this reason, some experts recommend early prophylactic cranial vault expansion on the basis that if ICP is not currently raised, it is likely to become so. The aim of this study was to examine the justification for such a policy. This was done by analyzing the incidence, causes, and subsequent risk of recurrence in a series of patients with CS, in whom raised ICP was treated only after it had been diagnosed. METHODS This study was a retrospective review of the medical records and imaging data of patients with a clinical diagnosis of CS. RESULTS There were 49 patients in the study, of whom 30 (61.2%) developed at least 1 episode of raised ICP. First episodes occurred at an average age of 1.42 years and were attributable to craniocerebral disproportion/venous hypertension (19 patients), hydrocephalus (8 patients), and airway obstruction (3 patients). They were managed, respectively, by vault expansion, ventriculoperitoneal shunt insertion, and airway improvement. Fourteen of the 30 patients developed a second episode of raised ICP an average of 1.42 years after treatment for their initial episode, and 3 patients developed a third episode an average of 3.15 years after that. Causes of subsequent episodes of raised ICP often differed from previous episodes and required different management. Patients who were < 1 year old when the first episode was diagnosed were at increased risk of recurrence. CONCLUSIONS Although the incidence of raised ICP in CS is high, it did not occur in nearly 40% of children during the course of this study. The several possible causes of CS require different management and may vary from episode to episode. The authors recommend an expectant policy toward these children with careful clinical, ophthalmological, respiratory, and radiological monitoring for raised

    2015-12-01

    The interactions that pig raisers in Bangladesh have with their pigs could increase the risk of zoonotic disease transmission. Since raising pigs is a cultural taboo to Muslims, we aimed at understanding the motivation for raising pigs and resulting practices that could pose the risk of transmitting disease from pigs to humans in Bangladesh, a predominantly Muslim country. These understandings could help identify acceptable strategies to reduce the risk of disease transmission from pigs to people. To achieve this objective, we conducted 34 in-depth interviews among pig herders and backyard pig raisers in eight districts of Bangladesh. Informants explained that pig raising is an old tradition, embedded in cultural and religious beliefs and practices, the primary livelihood of pig herders, and a supplemental income of backyard pig raisers. To secure additional income, pig raisers sell feces, liver, bile, and other pig parts often used as traditional medicine. Pig raisers have limited economic ability to change the current practices that may put them at risk of exposure to diseases from their pigs. An intervention that improves their financial situation and reduces the risk of zoonotic disease may be of interest to pig raisers.

  18. Raise boring through an artificially-frozen overburden in Canada

    Energy Technology Data Exchange (ETDEWEB)

    Roesner, E.

    1987-04-23

    The boring of ventilation shafts in solid ground by means of the raise-boring method has become standard procedure over the past twenty years. Also, raise boring through the permafrost has taken place, without any difficulties, at several mines in the Arctic. Thyssen Mining Construction of Canada Ltd. (TMCC) therefore felt that it would be a perfectly feasible proposition to bore through an artificially frozen overburden. In the autumn of 1984 the administration of the Pine Point mine invited tenders for the sinking of a small ventilation shaft; this was to have a diameter of 2.5 m and a depth of 60 m, going through 20 m of aquiferous overburden and 40 m of solid ground, on a site in a swampy area. The TMCC tender was for the artificial freezing of the overburden, prior to creating the ventilation shaft by raise boring. The shaft was successfully constructed according to the above method in the summer of 1985. The concrete lining was set with slide shuttering under the protection of the ice wall.

  19. Raising consciousness about the nuclear threat through music

    Energy Technology Data Exchange (ETDEWEB)

    Ungerleider, J.H.

    1987-01-01

    This dissertation examines the use of music, in particular topical collaborative group song writing, as a tool for raising consciousness about the threat of nuclear war. Consciousness raising is one way to overcome the phenomenon of denial and to increase discussion and social action in response to the nuclear threat. This dissertation measures the impact of a group song writing workshop on developing critical problem-solving in adult groups; it reviews how music is applied in psychological research and clinical work, has been used historically as a tool in social-change movements in America, and is used in the contemporary field of peace education. The perspectives of several theorists who discuss the potential of music to contribute to social change are presented. It is concluded that consciousness about the nuclear threat - in terms of naming and analyzing - can be raised by working with music's potential for developing affective, expressive, and collaborative capabilities in individuals and groups. Potential applications of the group song writing workshop are in schools, with peace organizations, music groups, and in relation to other social issues.

    This paper questions the view that a rise of the retirement age does not reduce the financial problems of a pay-as-you-go public pension system if individuals receive compensations for additional years spent in the labor force. It is shown that rather utility compensation is required than actuarial compensation. As the former is lower it creates an opportunity to raise the retirement age in a Pareto-improving way. By performing a dynamic CGE analysis for Germany, a compensation scheme is deri...

  5. Raised Relief Mars Globe Brings the Red Planet Closer

    Science.gov (United States)

    2006-01-01

    The Mars Globe 20x is the first digitally produced raised relief globe to be sold at retail establishments. The rises and dips of the Martian landscape have been multiplied by 20 to make the shapes more noticeable to human touch and sight. They make this globe, with its over 1 million elevation points, a visually stunning introduction to the planet. Spectrum 3D used the NASA digital land elevation data to aim lasers that then shaped and defined the master globe s surface. Subsequent copies were then made by creating a master globe mold. The molded copies are hand finished by workers who remove errant edges or lines that may appear on the raw globes and then paint the surfaces. The result is a globe that measures in at 18 inches in diameter, roughly 1:15,729,473 scale of the actual planet. The exaggerated raised relief is like having a 3-D digital microscope for planetary shapes. This makes the landmarks easier to learn and understand, as it provides easy visuals for orientation. People have a natural propensity for understanding 3-D shapes more easily than numbers or words. The 3-D globes appeal to both the kinetic and visual learning aspects of the brain, making it easy for people to readily memorize the landmarks and to make a mental model that they will remember for a long time.

  6. Civil engineering work to raise the level of Route Goward

    CERN Multimedia

    2013-01-01

    Civil engineering work to raise the level of Route Goward will take place during Long Shutdown 1. The work will begin on 18 March 2013 and is expected to last around 5 months.   Route Goward runs over the top of the PS tunnel and is the only access route to the inside of the ring. The layer of shielding backfill beneath this road is the thinnest anywhere on the PS ring. As the purpose of this shielding is to protect against the ionising radiation emitted by the accelerator when in operation, this road has been classified as a “supervised radiation area” according to radiation protection regulations. This classification was merely a temporary solution and, on the recommendation of the PS Radiation Working Group (PSRWG), the decision has been taken to raise the surface level permanently by around 2 m in order to increase the thickness of the shielding and thus lower the dose rate to that of a non-designated area. As the PS tunnel itself is unable to withstand the weight of t...

    Full Text Available Increasingly, all kinds of organizations and institutions are adopting the E-business model to conduct theiractivities and provide E-Services for their customers. In the process, whether they know it or not, thoseorganizations are also opening themselves up to the risk of information security breaches. Thereforeprotecting an organization’s ICT infrastructure, IT systems, and Data is a vital issue that is oftenunderestimated. Research has shown that one of the most significant threats to information security comesnot from external attack but rather from the system's users, because they are familiar with theinfrastructure and have access to its resources, but may be unaware of the risks. Moreover, using onlytechnological solutions to protect an organization’s assets is not enough; there is a need to consider thehuman factor by raising users’ security awareness. Our contribution to this problem is to propose anInformation Security Awareness Program that aims at raising and maintaining the level of users’ securityawareness. This paper puts forward a general model for an information security awareness program anddescribes how it could be incorporated into an organization’s website through the process of developmentlife cycle.

  8. Soil nitrogen and carbon impacts of raising chickens on pasture

    Science.gov (United States)

    Ryals, R.; Leach, A.; Tang, J.; Hastings, M. G.; Galloway, J. N.

    2014-12-01

    Chicken is the most consumed meat in the US, and production continues to intensify rapidly around the world. Chicken manure from confined feeding operations is typically applied in its raw form to nearby croplands, resulting in hotspots of soil nitrous oxide (N2O) emissions. Pasture-raised chicken is an alternative to industrial production and is growing in popularity with rising consumer demand for more humanely raised protein sources. In this agricultural model, manure is deposited directly onto grassland soils where it is thought to increase pools of soil carbon and nitrogen. The fate of manure nitrogen from pasture-raised chicken production remains poorly understood. We conducted a controlled, replicated experiment on a permaculture farm in Charlottesville, Virginia (Timbercreek Organics) in which small chicken coops (10 ft x 12 ft) were moved daily in a pasture. We measured manure deposition rates, soil inorganic nitrogen pools, soil moisture, and soil N2O and CO2 emissions. Measurements were made for the 28-day pasture life of three separate flocks of chickens in the spring, summer, and fall. Each flock consisted of approximately 200-300 chickens occupying three to five coops (~65 chickens/coop). Measurements were also made in paired ungrazed control plots. Manure deposition rates were similar across flocks and averaged 1.5 kgdrywt ha-1 during the spring grazing event and 4.0 kgdrywt ha-1 during the summer and fall grazing events. Manure deposition was relatively constant over the four weeks pasture-lifetime of the chickens. Compared to control plots, grazed areas exhibited higher soil N2O and CO2 fluxes. The magnitude of these fluxes diminished significantly over the four-week span. Soil gas fluxes significantly increased following rainfall events. For a given rainfall event, higher fluxes were observed from transects that were grazed more recently. Soil gaseous reactive nitrogen losses were less in this pasture system compared to cultivated field amended

  9. RAISING STUDENT’S AWARENESS ABOUT WRITING IN ENGLISH

    Institute of Scientific and Technical Information of China (English)

    2001-01-01

    In recent years, although college students have acquired ahigh level of proficiency in English reading, they have made verylittle advancement in English writing. This is due to the factthat inadequate importance is attached to writing in the teachingof English, and that students have rather vague ideas about therole of writing in foreign language learning and about the differ-ent discourse patterns existing between English and Chinese.Thus, this paper suggests that, in order to improve students’writing ability, two ways be adopted to raise students’ awarenessof learning to write: 1) integrating the product-oriented ap-proach with the process-oriented approach; 2) using students’reading as a writing source.

  10. Raising Relational Critical Consciousness to Enhance Empathy in Clinical Hypnosis.

    Science.gov (United States)

    Vargas, H Luis

    2016-01-01

    Empathic involvement theory suggests that a trance-like experience occurs when a cross-relational empathic connection is achieved. The empathically-laden relational phenomenon is thought to enhance hypnosis. Empathic involvement theory suggests hypnotizables are highly empathic. By the same token, the relational empathic connection necessitates a highly empathic practitioner of hypnosis. In the United States, where values of individualism are thought to be socially embedded and internalized, practitioners of hypnosis and clients alike may be impeded by an individually oriented worldview to empathically connect with others. Raising a relational critical consciousness is promoted as a way to increase sensitivity to the marginalization of relationships, limit empathic-effort burn-out, and promote cross-relational empathic connection.

  11. Saltation Impact as a Means for Raising Dust on Mars

    Science.gov (United States)

    Greeley, Ronald

    2002-01-01

    Experiments were conducted under atmospheric pressures appropriate for Earth and Mars to determine the efficiency of sand in saltation as a means for raising dust into the atmosphere under wind speeds which would otherwise be too low for dust entrainment. Experiments involving intimate mixtures of sand and dust (1:1 ratio by mass) showed that after an initial flurry of activity of a few seconds duration, the bed stabilized with little movement of either sand or dust. In contrast, sands set into saltation upwind fro= dust beds were efficient in injecting the dust into suspension, with low-pressure Martian conditions being some five times more efficient than terrestrial conditions. This result is attributed to the higher kinetic energies of the saltating grains on Mars, which is a consequence of the higher velocities of the grains. These results suggest that sands saltating across dust beds on Mars are an effective means for setting dust into suspension.

  12. THE CHALLENGES OF RAISING REVENUES AND RESTRUCTURING SUBSIDIES IN MALAYSIA

    Directory of Open Access Journals (Sweden)

    Suresh Narayanan

    2007-01-01

    Full Text Available Malaysia has run deficit budgets in all but five years since 1970 but past deficits have been managed thanks to substantial oil revenues and high domestic savings. However, the slow growth or decline of several traditional sources of revenue and the rising subsidy bill since 2007 have given pause for reflection on the traditional approach to fiscal management. In this paper, it is argued that fiscal management must not only centre around reducing non-productive expenditures and wasteful leakages but must also confront the problem of reducing and restructuring subsidies, particularly to petrol and petroleum-related products. The global dip in petroleum process has fortuitously provided the respite needed for such an exercise and should not lull policy makersinto complacency. When the economy recovers from the currentdownswing, a solid revenue raising instrument such as the value-addedtax must be introduced in order to wean the economy away from thecurrent over reliance on petroleum-based taxes.

    Louis Braille was born on January 4th 1809 in Coupvray, France. An injury to his eye at the age of three, resulted in total loss of vision. In 1819 he entered the Institute for Blind Youth in Paris. There he would live, study, and later teach. When he was fifteen, he developed system of reading and writing by means of raised dots, which is known today as Braille. The basis of the Braille system is known as a Braille cell. The cell is comprised of six dots numbered in a specific order. Each dot or combination of dots represents a letter of the alphabet. This Braille system has established itself internationally and formed the basic Braille for all languages.

    We consider the first-order finite-difference expression of the commutator between d / dx and x. This is the appropriate setting in which to propose commutators and time operators for a quantum system with an arbitrary potential function and a discrete energy spectrum. The resulting commutators are identified as universal lowering and raising operators. We also find time operators which are finite-difference derivations with respect to the energy. The matrix elements of the commutator in the energy representation are analyzed, and we find consistency with the equality [hat{T},hat{H}]=ihbar . We apply the theory to the particle in an infinite well and for the Harmonic oscillator as examples.

    2013-01-01

    Full Text Available This study compared the effectiveness of three techniques for teaching English vocabulary to Persian native speakers: a traditional procedure, the classical cloze procedure, and an innovative procedure, which is dubbed here as vicinity technique, based on incidental learning, noticing and consciousness-raising. To do the comparison, 51 students, registered at a private language institute, were randomly assigned to three groups and were taught 40 vocabulary items in five sessions in the three procedures. To evaluate the vocabulary gain in the three conditions, immediate and delayed post-tests were administered and the obtained data were analyzed using ANOVA. The results revealed that the vicinity technique was more effective than the traditional procedure; both in immediate and delayed evaluations. It was also revealed that, although there was no significant difference between the vicinity technique and the classical cloze technique in short-term, the vicinity technique was more effective than the classical cloze one for long-term retention.

    2004-10-01

    A trade off between conventional liquid apogee engines used for orbit raising applications and hybrid rocket engines (HRE) has been performed using a case study approach. Current requirements for lower cost and enhanced safety places hybrid propulsion systems in the spotlight. For evaluating and design of a hybrid rocket engine a parametric engineering code is developed, based on the combustion chamber characteristics of selected propellants. A single port cylindrical section of fuel grain is considered. Polyethylene (PE) and hydroxyl-terminated polybutadiene (HTPB) represents the fuels investigated. The engine design is optimized to minimize the propulsion system volume and mass, while keeping the system as simple as possible. It is found that the fuel grain L/D ratio boundary condition has a major impact on the overall hybrid rocket engine design.

    Full Text Available Background: Premature rupture of membrane (PROM is one of the common complications of pregnancy that has major impact on fetal and neonatal outcome. It is the commonest clinical event where a normal pregnancy becomes suddenly a high-risk one for mother and fetus or neonate. Objective: The study was undertaken to investigate whether raised fibronectin level in vaginal fluid may indicate premature rupture of membrane. Materials and Methods: This cross sectional study was conducted in the department of Obstetrics and Gynecology in Sir Salimullah Medical College & Mitford Hospital, Dhaka during the period of January 2006 to December 2007. A total of 114 pregnant women with gestational age 28th week up to 40th week were included. Sixty were PROM (Group I and 54 were non-PROM (Group II subjects. Fibronectin in vaginal fluid was measured by an immunochemical reaction by nephelometer. Statistical analysis was done by SPSS version 10.0. Results: The PROM patients had significantly higher concentration of fibronectin (225.77 ± 115.18 ng/mL compared to that in non-PROM subjects (8.04 ± 16.17 ng/mL (p < 0.001. Conclusion: It can be concluded that in cases of unequivocal rupture or intactness of the membranes, the result of the fibronectin test corresponds well with the clinical situation. So fibronectin is a sensitive test for detection of amniotic fluid in the vagina.

    2013-01-01

    Our environment is under constant pressure and threat from various sources of pollution. Science students, in particular chemistry students, must not only be made aware of these issues, but also be taught that chemistry (and science) can provide solutions to such real-life issues. To this end, a newly developed biochemistry laboratory experiment is described that guides students to learn about the applicability of peroxidase enzymes to degrade organic dyes (as model pollutants) in simulated waste water. In addition to showing how enzymes can potentially be used for waste water remediation, various factors than can affect enzyme-based reactions such as pH, temperature, concentration of substrates/enzymes, and denaturants can also be tested. This "applied biotechnology" experiment was successfully implemented in an undergraduate biochemistry laboratory course to enhance students' learning of environmental issues as well important biochemistry concepts. Student survey confirmed that this laboratory experiment was successful in achieving the objectives of raising environmental awareness in students and illustrating the usefulness of chemistry in solving real-life problems. This experiment can be easily adopted in an introductory biochemistry laboratory course and taught as an inquiry-guided exercise.

  1. Toward raising the higher level of radiological nursing

    International Nuclear Information System (INIS)

    The role and purpose of nursing in the radiological field are discussed with essentials of radiological nursing for raising its higher level and needed fundamental education. The discussion is from the thought that, at Fukushima Nuclear Power Plant Accident (Mar. 2011), general medical staff including nurses are rather insufficient of radiological knowledge like the exposure, radiation effect and risk. In the medical radiological field, nurses are expected to play roles of arranging the circumstance for patient's ease like explanation about health effect/risk, appropriate nursing of them after radiological diagnosis, radiation protection of nurses themselves, and of environment. At such an emergency as the Accident, care for the acutely exposed victims, their decontamination and responding to patient's concern are necessary. At the later phase, also needed are nursing of victims undergoing health management done by authorities and of radiological workers concerned as well as the third item above. Therefore, fundamentals of radiological knowledge such as physics, exposure, health effects, protection, contamination, legal rules and risk communication are required in the education of nurses. Otherwise, this education can be conducted as a part of safety security and physical assessment. The Accident also gives us the importance of radiological risk communication with its victims. (T.T.)

    Full Text Available  Purpose: To determine the parenting stress and its determinants among parents of children with disabling conditions in India.Methods: The Parenting Stress Index – short form and a few open ended questions were administered to a convenience sample of sixty-six patient families in July, 2009 in the cities of New Delhi and Faridabad regions of Northern India through six non- governmental organizations (NGOs that serve children with disabling conditions. Results: Female sex of the child was associated with higher stress related to failure of the child to meet parent’s expectations and to satisfy the parents in their parenting role. Parents engaged in more lucrative and prestigious occupations had more stress than parents engaged in less prestigious and lucrative occupations irrespective of their income. Many parents reported receiving little support from their extended families in taking care of their child. Religion was found to be a common coping resource used by the parents.Conclusion and Implications: Higher parenting stress in parents of girls raises the possibility of abuse and neglect. Little support from informal family resources underscores the need for developing formal resources for supporting the parents. The specific resources of parenting stress among parents of different socioeconomic status should be explored in future studies so that appropriate interventions can be planned.doi 10.5463/DCID.v23i2.119

    Full Text Available In the first experiment 360 Pannon White kits from 45 litters were divided into 3 groups. The kits in group SS were suckled once a day during the first 35 days of life (traditional method of nursing. Group DD was raised by 2 does and the kits were suckled both in the morning and in the evening until 35 days of age. The kits of the 3 rd group (D0 were suckled twice a day for 23 days, after which they were weaned. Rabbits which were suckled twice a day consumed 89 % more milk until 23 days of age than those of the SS kits. In the second experiment authors used different management systems, to investigate the possibilities of “double-suckling”. Both nulliparous as multiparous does were treated to induce pseudopregnancy (by means of GnRH. They were used as second doe and suckled the kits in the afternoon. Pseudopregnant does produced milk (nulliparous does less than does which had previously produced litters, but in conditions of controlled suckling they were not willing to suckle the young. In a third experiment, does (n=44 were inseminated 11 days after kindling. Weaning was performed at the age of 21 days and does could systematically serve as second mother for the litters born at the same day. The “additional” does that nursed the young in the afternoon produced 65 % of the milk quantity produced by the natural mother between days 0 and 21.

    Based on (1) the epimerization of L:isoleucine to D:alloisoleucine ( {D}/{L} ratios) in Patella vulgata, Littorina littorea, L. littoralis, L. saxatilis, Littorina species and Nucella lapillus from raised beaches in south west Britain, (2) statistical analysis of the {D}/{L} ratios, and (3) lithostratigraphic and geomorphic evaluation, three ( {D}/{L}) Stages are proposed. The {D}/{L} ratios for all the species measured are converted to a Patella vulgata standard. The three ( {D}/{L}) Stages are: (1) The Minchin Hole ( {D}/{L}) Stage, {D}/{L} ratios 0.175 ± 0.014, defined at a stratotype in Minchin Hole Cave, Gower, Wales. (2) A provisionally defined, but as yet, unamed ( {D}/{L}) Stage, because of the current unavailability of a suitable stratotype, with {D}/{L} ratios of 0.135 ± 0.014 (3) The Pennard ( {D}/{L}) Stage, {D}/{L} ratios 0.105 ± 0.016, defined at a stratotype in Minchin Hole Cave, Gower, Wales. Two geochronological models of the three high sea-level events representing the {D}/{L} Stages are constrained by uranium-series age determinations on stalagmite interbedded with marine beds in Minchin Hole and Bacon Hole Caves, Gower, Wales. A potential 'fixed point' in model evaluation is an age determination which is equivalent to Oxygen Isotope Sub-stage 5e (122 ka). The two models are:

  5. The Potential of Book Floods for Raising Literacy Levels

    Elley, Warwick B.

    2000-07-01

    The problem of raising literacy levels in developing countries is particularly challenging when pupils have their schooling in a non-native language. One promising strategy which has been tried and evaluated in the schools of several developing countries is the Book Flood approach. This article summarises the findings of Book Flood studies in Niue, Fiji, Singapore, Sri Lanka, South Africa, Solomon Islands, and several other countries. The evidence is now strong that it is possible to double the rate of reading acquisition of Third World primary school pupils with a "Book Flood" of about 100 high-interest books, per class, and short teacher training sessions. The benefits for reading skill and enthusiasm are consistent across diverse cultures, mother tongues and age levels, and they appear to generate corresponding improvements in children's writing, listening comprehension, and related language skills. Such skills are typically found to develop very slowly under traditional textbook styles of teaching. The problems of cost per school and cultural suitability of imported books are addressed. Several countries have adopted Book Flood programmes on a national scale, and others are currently planning to do so.

    2014-01-01

    Soluble P-selectin (sP-selectin), a biomarker of inflammatory related pathologies including cardiovascular and peripheral vascular diseases, also has pro-atherosclerotic effects including the ability to increase leukocyte recruitment and modulate thrombotic responses in vivo. The current study explores its role in progressing atherosclerotic plaque disease. Apoe-/- mice placed on a high fat diet (HFD) were given daily injections of recombinant dimeric murine P-selectin (22.5 µg/kg/day) for 8 or 16 weeks. Saline or sE-selectin injections were used as negative controls. In order to assess the role of sP-selectin on atherothrombosis an experimental plaque remodelling murine model, with sm22α-hDTR Apoe-/- mice on a HFD in conjunction with delivery of diphtheria toxin to induce targeted vascular smooth muscle apoptosis, was used. These mice were similarly given daily injections of sP-selectin for 8 or 16 weeks. While plaque mass and aortic lipid content did not change with sP-selectin treatment in Apoe-/- or SM22α-hDTR Apoe-/- mice on HFD, increased plasma MCP-1 and a higher plaque CD45 content in Apoe-/- HFD mice was observed. As well, a significant shift towards a more unstable plaque phenotype in the SM22α-hDTR Apoe-/- HFD mice, with increased macrophage accumulation and lower collagen content, leading to a lower plaque stability index, was observed. These results demonstrate that chronically raised sP-selectin favours progression of an unstable atherosclerotic plaque phenotype.

  9. An under-met and over-met expectations model of employee reactions to merit raises.

    Science.gov (United States)

    Schaubroeck, John; Shaw, Jason D; Duffy, Michelle K; Mitra, Atul

    2008-03-01

    The authors developed a model of how raise expectations influence the relationship between merit pay raises and employee reactions and tested it using a sample of hospital employees. Pay-for-performance (PFP) perceptions were consistently related to personal reactions (e.g., pay raise happiness, pay-level satisfaction, and turnover intentions). Merit pay raises were strongly related to reactions only among employees with high raise expectations and high PFP perceptions. The interactive effects of under-met/over-met expectations and PFP perceptions were mediated by the extent to which participants saw the raise as generous and they were happy with the raises they received. The authors discuss the implications of these findings for expectation-fulfillment theories, merit pay research, and the administration of incentives.

    Full Text Available A brief description of the nanotechnological inventions is given. The inventions in the area of nanotechnologies and nanomaterials produce a profound effect in construction, housing and communal services and adjacent economic fields as they allow us: to obtain high strength and durability of surfaces of the details, to provide different materials with hydrophil properties, to increase efficiency of transformation of light energy into electrical one etc., and in general – to raise competitive ability of the products. For example, the method of production of solar element and a unit of solar elements (RU 2532137 comprises following stages: formation of pn-transfer in semiconductor base plate, formation of passivating layer on the light-receptive surface and/or non light-receptive surface of semiconductor base plate and formation of power robbing electrodes on the light-receptive surface and non light-receptive. A film of aluminium oxide is formed as passivating layer, its thickness is up to 40 nm, and lectrode is formed by baking conductive paste under the temperature 500–900ͦͦ°C for 1 second – 30 inutes with formation of sintered product. The sintered product penetrates through passivating layer setting electric contact between electrode and base plate. The formation of aluminium ide with specified thickness on the surface of base plate makes it possible to achieve good passivating characteristics and good electric contact between silica and electrode only by eans of baking conductive paste, that is standard technology. Moreover the baking stage which was necessary to get the effect of film passivation for aluminium oxide in the past now can be cancelled to decrease costs. The specialists may be also interested in the following nanotechnological inventions: reinforced flaked element made of natural or conglomerate stone and its multilayer protective coating (RU 2520193; fine organic suspension of carbon metal-containing nanostructures

  11. Chandra's Find of Lonely Halo Raises Questions About Dark Matter

    Science.gov (United States)

    2004-10-01

    Dark matter continues to confound astronomers, as NASA's Chandra X-ray Observatory demonstrated with the detection of an extensive envelope of dark matter around an isolated elliptical galaxy. This discovery conflicts with optical data that suggest a dearth of dark matter around similar galaxies, and raises questions about how galaxies acquire and keep such dark matter halos. The observed galaxy, known as NGC 4555, is unusual in that it is a fairly large, elliptical galaxy that is not part of a group or cluster of galaxies. In a paper to be published in the November 1, 2004 issue of the Monthly Notices of the Royal Astronomical Society, Ewan O'Sullivan of the Harvard-Smithsonian Center for Astrophysics in Cambridge, MA and Trevor Ponman of the University of Birmingham, United Kingdom, use the Chandra data to show that the galaxy is embedded in a cloud of 10-million-degree-Celsius gas. X-ray/Optical Composite of NGC 4555 X-ray/Optical Composite of NGC 4555 This hot gas cloud has a diameter of about 400,000 light years, about twice that of the visible galaxy. An enormous envelope, or halo, of dark matter is needed to confine the hot cloud to the galaxy. The total mass of the dark matter halo is about ten times the combined mass of the stars in the galaxy, and 300 times the mass of the hot gas cloud. A growing body of evidence indicates that dark matter - which interacts with itself and "normal" matter only through gravity - is the dominant form of matter in the universe. According to the popular "cold dark matter" theory, dark matter consists of mysterious particles left over from the dense early universe that were moving slowly when galaxies and galaxy clusters began to form. "The observed properties of NGC 4555 confirm that elliptical galaxies can posses dark matter halos of their own, regardless of their environment," said O'Sullivan. "This raises an important question: what determines whether elliptical galaxies have dark matter halos?" DSS Optical Image of NGC

  12. Raising public awareness of nuclear science in action

    International Nuclear Information System (INIS)

    Nobel Prize for Maria Skodowska-Curie), the schools - after visiting us - try to organise their own minisymposia on the radioactivity, the visitors seem to receive proper message about the real risk connected with nuclear radiation. The latter is judged by the fact that very seldom we encounter typical symptoms of radio phobia after the visit to our Department. We are strongly convinced that our work will result in an increased interest of students in physics, and may regain the popularity of nuclear physics among the students. This is necessary if the nuclear energy is going to be developed and used safely in the country. We also believe that similar educational centres, if wherever absent, should be organised in other nuclear centres in Europe and all of them should form a network in which new didactical methods would be worked out and the experience could be easily evaluated and exchanged between the network's partners. The paper presents motivation, present status, methodology and results of our more than 5-years experience in raising public awareness of nuclear problems in various social groups. (author)

    Kazakhstan is one of the nine largest countries of the world and not only has significant mineral resources but rich geological heritage. However, to date geology is considered only as a way to search for minerals due to the established traditions. Faced with a geologist, we usually ask: "What are you looking for?". But the man with the hammer must answer the more important question - about the future of the Planet and Humanity. But it is necessary to save and to study the stone chronicle page for this. Only history of the Earth, recorded in the annals of rock sheets, gives a scientific answer on the fate of Planet and Mankind, and allows realistically assess the risk of disasters, floods, global warming, etc. During 20 years we are trying to give a push to protection and use of geological heritage of Kazakhstan. In our country this new direction gets accustomed with large labor. The spread of the world experience on geoconservation, the databases created of the geological heritage of Kazakhstan, numerous performances in the scientific press and the media has not lead to real steps to preserve and use geodiversity in our country. Today we are trying to raise the idea of geoconservation in Kazakhstan based on Geoparks. A project "Geological study of the geoparks development in Kazakhstan" is developed. 12 representative areas were selected on a background of the database that includes 500 sites of geological heritage, embracing a large variety of geological processes in all regions of Kazakhstan. On October 31st, 2012 in Astana the "Kazakh Geographical Society" held an international conference including "Geoparks" section. At the conference reports of all the regions of Kazakhstan representatives were presented, as well as European countries with extensive experience in geoconservation and geoparks creation (Portugal, Bulgaria, Turkey). The conference was supported by UNESCO. Album "Millions of years before the Silk Road", which represents the future Kazakhstan

  14. Seismic monitoring experiment of raise boring in 2014

    2015-01-15

    In Olkiluoto, Posiva Oy has operated a local seismic network since February 2002. The purpose of the microearthquake measurements at Olkiluoto is to improve understanding of the structure, behaviour and long term stability of the bedrock. The studies include both tectonic and excavation-induced microearthquakes. An additional task of monitoring is related to safeguarding of ONKALO. The possibility to excavate an illegal access to ONKALO has been concerned when the safeguards are discussed. Therefore all recorded explosions in the Olkiluoto area and in ONKALO are located. If a concentration of explosions is observed, the origin of that is found out. Also a concept of hidden illegal explosions, detonated at the same time as the real excavation blasts, has been examined. According to the experience gained in Olkiluoto, it can be concluded that, as long the seismic network is in operation and the results are analysed by a skilled person, it is practically impossible to do illegal undetected excavation by blasting within the Olkiluoto seismic network area. In this report a possibility of seismic monitoring of undeclared excavation done by tunnel boring machine (TBM) has been investigated. In the earlier investigations the instruments were at the ground surface and the sensors were triaxial short period (1 Hz) geophones or broadband geophones. The characteristics (frequency content, polarity and amplitude) of the continuous seismic vibration generated by TMB were studied. The onset time of the seismic signal were not distinguished. Altogether 16 new 10 kHz accelerometers were installed in boreholes inside ONKALO March 2012. The sensors comprised a new subnetwork that monitored the raise boring of two shafts done 2014, from the level -455 m to the level -290 m. The aim was to record the seismic signal generated when the drill bit hits the rock at the moment the tunnel boring begins. Altogether 113 seismic signals generated by the drill bit were located during the

  16. [Being raised by lesbian parents or in a single-parent family is no risk factor for problem behavior, however being raised as an adopted child is].

    Verhulst, F C; Versluis-den Bieman, H O; Balmus, N C

    1997-03-01

    Modern reproductive techniques and alternative family structures (with single or homosexual parents and adoption situations) raise questions about the consequences for the growing children involved. Genetic links appear to be less important for the functioning of a family than a strong wish for parenthood; parents who have become parents only through great efforts display a better quality of parenthood than average natural parents. Characteristics of the parent/parents, such as paedagogic qualities, and the quality of the parent-child relationship appear more important than the type of family. Published results of research reveal no reason why lesbian families should be judged differently from heterosexual ones as family types for the raising of children. The main negative factor for the functioning of the child growing up in a single-parent family is the marriage conflicts that have led to the single-parent situation; being raised by a single parent in itself has no adverse effect. Raising adopted children from other countries makes far greater demands on the adoptive parents than parents of biological children have to meet. The raising of a foreign adopted child by a single parent entails additional risks for the child's development. Data on the development of children in alternative family structures frequently concern exceptionally competent parents, which may have biased the findings.

    A new identity is proved that represents the kth order B-splines as linear combinations of the (k + 1) th order B-splines A new method for degree-raising of B-spline curves is presented based on the identity. The new method can be used for all kinds of B-spline curves, that is, both uniform and arbitrarily nonuniform B-spline curves. When used for degree-raising of a segment of a uniform B-spline curve of degree k - 1, it can help obtain a segment of curve of degree k that is still a uniform B-spline curve without raising the multiplicity of any knot. The method for degree-raising of Bezier curves can be regarded as the special case of the new method presented. Moreover, the conventional theory for degree-raising, whose shortcoming has been found, is discussed.

    2016-07-01

    Pre-Columbian raised field agriculture in the tropical lowlands of South America has received increasing attention and been the focus of heated debates regarding its function, productivity, and role in the development of pre-Columbian societies. Even though raised fields are all associated to permanent or semi-permanent high water levels, they occur in different environmental contexts. Very few field-based studies on raised fields have been carried out in the tropical lowlands and little is known about their use and past management. Based on topographic surveying and mapping, soil physical and chemical analysis and OSL and radiocarbon dating, this paper provides insight into the morphology, functioning and time frame of the use of raised fields in the south-western Llanos de Moxos, Bolivian Amazon. We have studied raised fields of different sizes that were built in an area near the town of San Borja, with a complex fluvial history. The results show that differences in field size and height are the result of an adaptation to a site where soil properties vary significantly on a scale of tens to hundreds of metres. The analysis and dating of the raised fields sediments point towards an extensive and rather brief use of the raised fields, for about 100-200 years at the beginning of the 2nd millennium.

    2012-01-01

    Full Text Available This study investigated how CLT (Communicative Language Teaching and awareness-raising enhanced Thai learners’ awareness of their local wisdom in a tour-related project work with three specific purposes, which were to explore how the learners interacted with textual representations of their local wisdom to create their project, what extent CLT and awareness-raising tasks developed their communicative competence of the target language, and what object of awareness that the tasks could help the learners realize while working on their projects. This study was triangulated. The elicitation instruments were project instructions, CLT and awareness-raising tasks, pretests and posttests based on TOEIC (Test of English for International Communication, learner logs, interviews, and observation notes. The study revealed that, first, on the awareness of local wisdom in a tour-related project work, the learners interacted with textual representations of their local wisdom through theme-centered learning process. Second, on the enhancement of CLT and awareness-raising, CLT allowed the learners to deal with interactive, spontaneous, and more meaningful communication actively while awareness-raising helped the learners consciously focus on semantic, linguistic, and pragmatic aspects of the target language. Lastly, on object of awareness, CLT and awareness-raising tasks could lead the learners to realize these objects of awareness: nature of experiential learning, subject content, and skill content. For pedagogical implications, project-based teaching with the support of CLT and awareness-raising tasks can raise learner awareness of local wisdom in tour-related topics effectively. Pedagogical implications illustrated some practical applications of CLT and awareness-raising tasks for enhancing learner awareness in ESP project work in a Thai classroom. Future inquiry should replicate this study or apply to business or other ESP project instructions.

  17. California gull chicks raised near colony edges have elevated stress levels

    Science.gov (United States)

    Herring, Garth; Ackerman, Joshua T.

    2011-01-01

    Coloniality in nesting birds represents an important life history strategy for maximizing reproductive success. Birds nesting near the edge of colonies tend to have lower reproductive success than individuals nesting near colony centers, and offspring of edge-nesting parents may be impaired relative to those of central-nesting parents. We used fecal corticosterone metabolites in California gull chicks (Larus californicus) to examine whether colony size or location within the colony influenced a chick's physiological condition. We found that chicks being raised near colony edges had higher fecal corticosterone metabolite concentrations than chicks raised near colony centers, but that colony size (ranging from 150 to 11,554 nests) had no influence on fecal corticosterone levels. Fecal corticosterone metabolite concentrations also increased with chick age. Our results suggest that similarly aged California gull chicks raised near colony edges may be more physiologically stressed, as indicated by corticosterone metabolites, than chicks raised near colony centers.

    Old World monkeys solicit allo-grooming from conspecifics. However, there are relatively few studies of allo-grooming among spider monkeys, and descriptions of allo-grooming solicitation among spider monkeys are anecdotal. In this study, eighty-one hours of video, shot over eight weeks, captured 271 allo-grooming bouts among small groups of captive spider monkeys. Six of eight monkeys made heretofore unreported arm-raises that solicited higher than normal rates of allo-grooming. Allo-grooming bout durations following arm-raises also tended to be longer than bouts not preceded by arm-raises. The efficacy of the arm-raise at soliciting allo-grooming suggests spider monkeys are capable of intentional communication.

  11. The processing of raising and nominal control: An eye-tracking study

    Directory of Open Access Journals (Sweden)

    Patrick eSturt

    2015-03-01

    Full Text Available According to some views of sentence processing, the memory retrieval processes involved in dependency formation may differ as a function of the type of dependency involved. For example, using closely matched materials in a single experiment Dillon et al (2013 found evidence for retrieval interference in subject-verb agreement, but not in reflexive-antecedent agreement. We report four eye-tracking experiments that examine examine reflexive-antecedent dependencies, combined with raising (e.g. ``John seemed to Tom to be kind to himself...'', or nominal control (e.g. ``John’s agreement with Tom to be kind to himself...''. We hypothesized that dependencies involving raising would (a be processed more quickly, and (b be less subject to retrieval interference, relative to those involving nominal control. This is due to the fact that the interpretation of raising is structurally constrained, while the interpretation of nominal control depends crucially on lexical properties of the control nominal. The results showed evidence of interference when the reflexive-antecedent dependency was mediated by raising or nominal control, but very little evidence that could be interpreted in terms of interference for direct reflexive-antecedent dependencies that did not involve raising or control. However, there was no evidence either for greater interference, or for quicker dependency formation, for raising than for nominal control.

  12. Pre-Columbian Agriculture: Construction history of raised fields in Bermeo, in the Bolivian Lowlands

    Rodrigues, Leonor; Fehr, Seraina; Lombardo, Umberto; Veit, Heinz

    2013-04-01

    Since the beginning of the 1960s, research in the Amazon has revealed that in Pre-Columbian times, landscapes that were viewed as challenging living environments were nevertheless altered in several ways. Raised fields agriculture is one of the most impressive phenomena that can be found in South-eastern Amazonia. Pre-Columbian raised fields are earth platforms of differing shape and dimension that are elevated above the landscape's natural surface. The Llanos de Moxos, situated in the Bolivian Lowlands is one of the areas with the highest density of raised fields. In spite of the high interest in raised field agriculture, very few field-based investigations have been performed. As a result, there remains little explanation as to how they were constructed, managed or for what time frame they were in use. Recently, more detailed investigations have been performed on raised fields located in the indigenous community of Bermeo, in the vicinity of San Ignacio de Moxos. Combined data from fieldwork and laboratory analysis including particle size distribution, thin section micromorphology and radiocarbon analyses as well as optically stimulated luminescence analysis has given an insight into the history of their construction. Applied to the Bolivian Lowlands, the current study provides for the first time data showing aspects of the Pre-Columbian management of the raised fields, and a chronological sequence of utilization and abandonment of these fields. Radiocarbon dating has shown that the raised fields had been in use since as early as 900 AD. Two distinct paleosols identified in the field sequence point to the existence of two separate prolonged soil formation periods. The paleosols are characterized by initial stages of Bt-horizons. Each soil sequence indicates therefore a particular stable period of the field during which no new earth was heaped up. This suggests that contrary to the well supported theory that raised fields were managed through continuous

    The disturbance of Pre Columbian populations on Amazonian ecosystems is being actively debated. The traditional view of amazon being an untouched landscape because of its poor soils and harsh climate has been challenged and the extreme opposite idea of highly modified landscapes with complex societies is growing. Recent research has led to new impulses and issues requesting about the agricultural strategies people developed to survive in this climate. The Llanos de Moxos, situated in the Bolivian Lowlands in south-eastern Amazonia is one important region which was densely altered and where a great variety of earthworks can be found. One of the most impressive earth works are the raised fields, which are earth platforms for cultivation of differing shape and dimension that are elevated above the landscapes natural surface. In contrast to the "terra preta" formation where artefacts and amendments like charcoal and kitchen waste have been clearly identified, raised fields have shown to be artefact poor and studies up till now couldn't find any evidence of additional amendments which could have improved soil quality in the long term. As a result the function and productivity of raised fields is still not well understood and is being actively discussed. Detailed investigations on raised fields located in the indigenous community of Bermeo, in the vicinity of San Ignacio de Moxos provides data showing a novel explanation of the Pre-Columbian management of raised fields, and a chronological sequence of their utilization and abandonment. OSL dating has shown that the raised fields had been in use since as early as 600 AD. Comparison of Geochemistry with a reference profile, away from raised fields, showed that there is no evidence for manure amendments deriving from kitchen waste or animal residues suggesting a rather extensive use of those fields.

    Full Text Available This article considers issues in Old English sociolinguistics, in relation to specific changes affecting the low front vowels in ninth-century Kentish, as manifest in spelling variation in charters of the time. This change is referred to as Kentish Raising (Hogg 1988. It is suggested that variationist sociolinguistics is not an appropriate framework within which to explain Kentish Raising, since the nature of the data is such that a variationist approach is untenable. A reconstruction of the social, political and cultural situation in ninth-century Kent is provided, which examines Mercian influence in the period, and suggests that a Mercian-driven change from above (Second Fronting cannot be the source of Kentish Raising. Finally, it is proposed that recent work in genetic anthropology, which seeks to discover more about the nature and extent of the continental migrations, may be useful in understanding the social context in which the varieties of Old English existed and developed.

    Seven children with drained hydrocephalus are described who showed increasingly severe and frequent episodes of intermittently raised intracranial pressure. CT examinations during symptom-free intervals, or after conservative treatment, showed collapsed slit-like ventricles. Examination during attacks of raised pressure showed relative dilatation of the ventricles as compared with earlier examinations. Children with ventricular shunts of long duration may develop a shunt-dependent syndrome; CT may show normal or narrow ventricles and this does not exclude the possibility of a rise of intracranial pressure. These findings may help in making the diagnosis by means of CT without any further invasive procedure.

    objective: To assess the cytogenetic toxicological safety of fish raised in water containing effluent. Methods: Three experimental groups of fish were raised in water that contained effluent. Both fish samples and water samples were collected and analyzed. One group of fish raised in YuQiao reservoir (The source of drinking-water for Tianjin) and a reservoir water sample were collected at the same time as the clean control group. The mutagenicity of organic extracts of the fish was detected using the mice bone marrow micronucleus test and the mutagenicity of the water samples was detected using the micronucleus test of vicia faba root tip cells. Results: The results of the mice bone marrow micronucleus test on organic extracts of the fish showed that the micronucleus rates of the three experimental groups were significantly higher than that of the negative control group (peanut oil) and the clean control group (P0.05) Conclusions: The results indicate that the water containing effluent and the fish raised in this kind of water contain some kinds of organic mutagenic compounds, which might have some potentially hazardous effects on human beings through the food chains.

    1998-01-01

    We examined the respiratory behaviours and swimming kinematics of Xenopus laevis tadpoles hatched in microgravity (Space Shuttle), simulated microgravity (clinostat) and hypergravity (3 g centrifuge). All observations were made in the normal 1 g environment. Previous research has shown that X. laevis raised in microgravity exhibit abnormalities in their lungs and vestibular system upon return to 1 g. The tadpoles raised in true microgravity exhibited a significantly lower tailbeat frequency than onboard 1 g centrifuge controls on the day of landing (day0), but this behaviour normalized within 9 days. The two groups did not differ significantly in buccal pumping rates. Altered buoyancy in the space-flight microgravity tadpoles was indicated by an increased swimming angle on the day after landing (day1). Tadpoles raised in simulated microgravity differed to a greater extent in swimming behaviours from their 1 g controls. The tadpoles raised in hypergravity showed no substantive effects on the development of swimming or respiratory behaviours, except swimming angle. Together, these results show that microgravity has a transient effect on the development of locomotion in X. laevis tadpoles, most notably on swimming angle, indicative of stunted lung development. On the basis of the behaviours we studied, there is no indication of neuromuscular retardation in amphibians associated with embryogenesis in microgravity.

  16. mRAISE: an alternative algorithmic approach to ligand-based virtual screening.

    2016-08-01

    Ligand-based virtual screening is a well established method to find new lead molecules in todays drug discovery process. In order to be applicable in day to day practice, such methods have to face multiple challenges. The most important part is the reliability of the results, which can be shown and compared in retrospective studies. Furthermore, in the case of 3D methods, they need to provide biologically relevant molecular alignments of the ligands, that can be further investigated by a medicinal chemist. Last but not least, they have to be able to screen large databases in reasonable time. Many algorithms for ligand-based virtual screening have been proposed in the past, most of them based on pairwise comparisons. Here, a new method is introduced called mRAISE. Based on structural alignments, it uses a descriptor-based bitmap search engine (RAISE) to achieve efficiency. Alignments created on the fly by the search engine get evaluated with an independent shape-based scoring function also used for ranking of compounds. The correct ranking as well as the alignment quality of the method are evaluated and compared to other state of the art methods. On the commonly used Directory of Useful Decoys dataset mRAISE achieves an average area under the ROC curve of 0.76, an average enrichment factor at 1 % of 20.2 and an average hit rate at 1 % of 55.5. With these results, mRAISE is always among the top performing methods with available data for comparison. To access the quality of the alignments calculated by ligand-based virtual screening methods, we introduce a new dataset containing 180 prealigned ligands for 11 diverse targets. Within the top ten ranked conformations, the alignment closest to X-ray structure calculated with mRAISE has a root-mean-square deviation of less than 2.0 Å for 80.8 % of alignment pairs and achieves a median of less than 2.0 Å for eight of the 11 cases. The dataset used to rate the quality of the calculated alignments is freely available

  17. Three-dimensional evaluation of heel raise test in pediatric planovalgus feet and normal feet.

    2016-07-01

    Planovalgus foot is a common pediatric deformity which may be associated with pain. To evaluate flexibility of the foot, the heel raise test is used. During this test the arch and hindfoot are assessed. Several studies have described planovalgus foot based on 3D gait and standing analysis. However, no studies have evaluated foot flexibility during heel raise using an objective 3D analysis. Therefore, the purpose of this study is to evaluate the flexibility of planovalgus feet during the heel raise test using an objective 3D assessment and to determine whether any hypotheses can be generated about potential differences between painful and painless flexible planovalgus feet and reference feet. Here, 3D foot analysis was conducted in 33 children (7 reference feet, 16 painless, and 10 painful flexible planovalgus feet) during the heel raise test. To identify the characteristics of planovalgus foot, the concept of 3D projection angles was used as introduced in the Heidelberg Foot Measurement Method (HFMM), with a modified marker set. All feet showed dynamic movements of the medial arch and hindfoot from valgus to varus position during heel raise. Reference feet had the smallest range of motion, perhaps due to joint stability and absence of foot deformity. Painful and painless flexible planovalgus feet demonstrated similar movements. No significant differences were found between the painful and painless groups. However, the kinematics of the pain group seemed to differ more from those of the reference group than did kinematics of the painless group. This assessment is a new, practical, and objective method to measure the flexibility of small children's feet. PMID:27262407

    Full Text Available The article looks at raising environmental awareness of students in the course of research performed at the university museum. The author assumes that environmental museum of a university can become the space for innovation and exploration that could raise environmental awareness of students. In order to ensure proper pedagogical conditions there was elaborated a concept of raising environmental awareness of students with the help of a university museum. The article follows the main stages of creation of the exposition by the students, which was devoted to the 5th year of environmental disaster, which was the result of a series of shipwrecks on the ‘black Sunday’ of 11 November, 2007 in the Kerch Strait.The author assumes that the exposition is essential to shed light on real events, present them more vividly, follow the history of certain exhibits and emphasize the unbearable living conditions for the birds dying in the oil slick. The exposition unveils core problems of oil contamination of the world ocean. The exhibits prove the actual fact and foster deeper understanding of the situation. They help to picture the tragic events of the black Sunday more vividly and evoke feelings and emotions, which make the students their witnesses and participants.The author follows the process of raising environmental awareness of students and looks at the results before and after their involvement in research at the environmental museum with the help of the method by E.V. Asafova and concludes that engaging students in research through creating ecological exposition can considerably raise their environmental awareness.DOI: http://dx.doi.org/10.12731/2218-7405-2013-8-24

    Recombinant fusion protein is widely used as an antigen to raise antibodies against the epitope of a target protein. However, the concomitant anticarrier antibody in resulting antiserum reduces the production of the desired antibody and brings about unwanted non-specific immune reactions. It is proposed that the carrier protein transgenic animal could be used to solve this problem. To validate this hypothesis, enhanced green fluorescent protein (EGFP) transgenic mice were produced. By immunizing the mice with fusion protein His6HAtag-EGFP, we showed that the antiserum from the transgenic mice had higher titer antibody against His6HA tag and lower titer antibody against EGFP compared with that from wild-type mice. Therefore, this report describes an improved method to raise high titer antipeptide polyclonal antibody using EGFP transgenic mice that could have application potential in antibodypreparation.

    Data presented here contains metagenomic analysis regarding the sequential conventionalization of germ-free zebrafish embryos. Zebrafish embryos that underwent a germ-free sterilization process immediately after fertilization were promptly exposed to and raised to larval stage in conventional fish water. At 6 days postfertilization (dpf), these "conventionalized" larvae were compared to zebrafish larvae that were raised in conventional fish water never undergoing the initial sterilization process. Bacterial 16S rRNA amplicon sequencing was performed on DNA isolated from homogenates of the larvae revealing distinct microbiota variations between the two groups. The dataset described here is also related to the research article entitled "Microbial modulation of behavior and stress responses in zebrafish larvae" (Davis et al., 2016) [1]. PMID:27508247

    Raised and transitional bogs are one of the most threatened types of ecosystem, due to high specialisation of biota, associated with adaptations to severe environmental conditions. The aim of the study was to characterize the relationships between functional diversity (reflecting ecosystem-shaping processes) of raised bog plant communities and successional gradients (expressed as tree dimensions) and to show how impacts of former clear cuts may alter these relationships in two raised bogs in 'Bory Tucholskie' National Park (N Poland). Herbaceous layers of the plant communities were examined by floristic relevés (25m(2)) on systematically established transects. We also assessed patterns of tree ring widths. There were no relationships between vegetation functional diversity components and successional progress: only functional dispersion was negatively, but weakly, correlated with median DBH. Lack of these relationships may be connected with lack of prevalence of habitat filtering and low level of competition over all the successional phases. Former clear cuts, indicated by peaks of tree ring width, influenced the growth of trees in the bogs studied. In the bog with more intensive clear cuts we found more species with higher trophic requirements, which may indicate nutrient influx. However, we did not observe differences in vegetation patterns, functional traits or functional diversity indices between the two bogs studied. We also did not find an influence of clear cut intensity on relationships between functional diversity indices and successional progress. Thus, we found that alteration of the ecosystems studied by neighbourhood clear cuts did not affect the bogs strongly, as the vegetation was resilient to these impacts. Knowledge of vegetation resilience after clear cuts may be crucial for conservation planning in raised bog ecosystems.

    2007-09-01

    An error was discovered in the ALGEBBRA script used to calculate the disturbed rock zone around the disposal room and the shear failure zone in the anhydrite layers in the original version. To correct the error, a memorandum of correction was submitted according to the Waste Isolation Pilot Plant (WIPP) Quality Assurance program. The recommended course of action was to correct the error, to repeat the post-process, and to rewrite Section 7.4, 7.5, 8, and Appendix B in the original report. The sections and appendix revised by the post-process using the corrected ALGEBRA scripts are provided in this revision. The original report summarizes a series of structural calculations that examine effects of raising the WIPP repository horizon from the original design level upward 2.43 meters. Calculations were then repeated for grid changes appropriate for the new horizon raised to Clay Seam G. Results are presented in three main areas: (1) Disposal room porosity, (2) Disturbed rock zone characteristics, and (3) Anhydrite marker bed failure. No change to the porosity surface for the compliance re-certification application is necessary to account for raising the repository horizon, because the new porosity surface is essentially identical. The disturbed rock zone evolution and devolution are charted in terms of a stress invariant criterion over the regulatory period. This model shows that the propagation of the DRZ into the surrounding rock salt does not penetrate through MB 139 in the case of both the original horizon and the raised room. Damaged salt would be expected to heal in nominally 150 years. The shear failure does not occur in either the upper or lower anhydrite layers at the moment of excavation, but appears above and below the middle of the pillar one day after the excavation. The damaged anhydrite is not expected to heal as the salt in the DRZ is expected to.

    Raised and transitional bogs are one of the most threatened types of ecosystem, due to high specialisation of biota, associated with adaptations to severe environmental conditions. The aim of the study was to characterize the relationships between functional diversity (reflecting ecosystem-shaping processes) of raised bog plant communities and successional gradients (expressed as tree dimensions) and to show how impacts of former clear cuts may alter these relationships in two raised bogs in 'Bory Tucholskie' National Park (N Poland). Herbaceous layers of the plant communities were examined by floristic relevés (25m(2)) on systematically established transects. We also assessed patterns of tree ring widths. There were no relationships between vegetation functional diversity components and successional progress: only functional dispersion was negatively, but weakly, correlated with median DBH. Lack of these relationships may be connected with lack of prevalence of habitat filtering and low level of competition over all the successional phases. Former clear cuts, indicated by peaks of tree ring width, influenced the growth of trees in the bogs studied. In the bog with more intensive clear cuts we found more species with higher trophic requirements, which may indicate nutrient influx. However, we did not observe differences in vegetation patterns, functional traits or functional diversity indices between the two bogs studied. We also did not find an influence of clear cut intensity on relationships between functional diversity indices and successional progress. Thus, we found that alteration of the ecosystems studied by neighbourhood clear cuts did not affect the bogs strongly, as the vegetation was resilient to these impacts. Knowledge of vegetation resilience after clear cuts may be crucial for conservation planning in raised bog ecosystems. PMID:27110977

  20. Mitigation of greenhouse gas fluxes from cultivated organic soils by raised water table

    2010-01-01

    Cultivated organic soils are a remarkable source of greenhouse gases (GHG) in some countries and raised ground water table has been suggested as a mitigation measure on these soils. Drainage of the peat increases mineralization of the organic matter and causes high emissions of carbon dioxide (CO2) and nitrous oxide (N2O) while emissions of methane (CH4) are lowered compared to pristine peatlands. In countries with a large area of organic soils these GHG emissions can be remarkable. In ...

    2014-06-01

    Full Text Available Adaptation to extreme weather is often considered as having a low urgency and being a low priority governance option, even though the intensity of extreme weather events is expected to increase as a result of climate change. An important issue is how to raise an adequate level of concern among individuals, policy makers, and broader decision makers in companies and organizations so that adaptation to extreme events becomes mainstream practice. We conducted 40 indepth interviews with individuals from different sectors in The Netherlands to identify the different types of experiences with extreme events, as well as the relationship between such experiences and the level of concern about extreme weather. Our results indicate that individuals who have experienced an intense, life-threatening event have a significantly higher level of concern than those without such an experience. Professional experience and secondhand experience through participating in information events do not significantly affect the level of concern about extreme events. This suggests limited intervention possibilities for communication of adaptation, as well as for raising support for adaptation measures. Framing adaptation measures in relation to personal circumstances and emotions during extreme events could help raise concern about extreme weather events, as well as societal support for adaptation measures.

    2004-01-01

    This report summarizes a series of structural calculations that examine effects of raising the Waste Isolation Pilot Plant repository horizon from the original design level upward 2.43 meters. These calculations allow evaluation of various features incorporated in conceptual models used for performance assessment. Material presented in this report supports the regulatory compliance re-certification, and therefore begins by replicating the calculations used in the initial compliance certification application. Calculations are then repeated for grid changes appropriate for the new horizon raised to Clay Seam G. Results are presented in three main areas: 1. Disposal room porosity, 2. Disturbed rock zone characteristics, and 3. Anhydrite marker bed failure. No change to the porosity surface for the compliance re-certification application is necessary to account for raising the repository horizon, because the new porosity surface is essentially identical. The disturbed rock zone evolution and devolution are charted in terms of a stress invariant criterion over the regulatory period. This model shows that the damage zone does not extend upward to MB 138, but does reach MB 139 below the repository. Damaged salt would be expected to heal in nominally 100 years. The anhydrite marker beds sustain states of stress that promote failure and substantial marker bed deformation into the room assures fractured anhydrite will sustain in the proximity of the disposal rooms.

    The collared peccary (Tayassu tajacu) is widely distributed over the American continent, being found from the south of the USA to the north of Argentina. In Brazil, it is spread all over the country, being one of the potential species to be raised in captivity. Therefore, the cytogenetic techniques could be a potential tool for reproductive monitoring of animals raised in captivity, mainly when destined for commercial purposes. This study had the objective of determining the chromosome number of two populations raised in captivity and characterizing them by GTG banding. For this purpose, an analysis was made of mitotic metaphases obtained from lymphocyte cultures made from blood samples of 11 animals, six of which from the Northeast and five from the North of Brazil. The results of this analysis showed the same karyotype pattern for the species (2n=30 chromosomes and NF=48), besides corresponding to the South American pattern of the species, i.e., without a translocation between autosomes 1 and 8, chromosome X acrocentric, and no differences were found between the two populations studied. However, chromosomal polymorphisms were observed compared to data from the literature on populations from North and South America.

    The AC-AC conversion circuit is generally a system to convert AC power into DC power, and then converts the DC power into AC power. However, an electrolytic capacitor to store DC power is a large obstacle for reducing the size and weight and extending the life of the equipment. Fuji Electric is promoting development of a direct conversion circuit to covert AC power into AC power having different frequencies and amplitudes without using an electrolytic capacitor. The figure shows the configuration of a voltage raising and dropping type direct conversion circuit (three-phase to three-phase). Making this type of circuitry makes direct AC-AC conversion and voltage raising and dropping operation possible, and reducing the size and weight and extending the life of the equipment may be expected. Therefore, high-frequency switching technology (15.6 kHz) was used to verify the operation of a functional prototype ( 10 kVA). As a result, voltage raising and dropping operation from input voltage of 100V AC to and from zero and 200V AC of the output voltage was realized with input current distortion of 5.9% and output voltage distortion of 3.7%.

    Full Text Available The objective of this study was to use morphometric and ultrasound evaluations to estimate the growth curve of the Pantaneiro cattle breed, raised in its natural habitat, aiming at the re-insertion of this breed in production systems. One hundred and three females, aging from months to 11 years, and raised on native pastures, were evaluated. The animals belonged to the Conservation Nucleus of Embrapa Pantanal, located in the Pantanal of Mato Grosso do Sul (Brazil. Weight, thoracic perimeter (TP, body length (BL, rump height (RH, height at withers (HW, hip height (HH, depth (DP, distance between the ilia (DI (cm and rib-eye area (REA were measured. To relate the measurements with the age of the animals, the univariate regression model was used, assigning the variable response to gamma distribution. The Pearson correlation between variables was also estimated. The inflection point of the growth curve was 37 months for HH; between 38 and 39 months for TP and HW; between 40 and 41 months for DI, HH and DP; and 45 months for BL. The REA results could not fit in a statistical model. The majority of the variables presented a correlation above 60% among themselves, except for REA × Age, of 15.81%; REA × HW, of 34.44%; HH × Age, of 46.19; HH × DI, of 58.07%; REA × HH, of 24.57%; and REA × TP, of 39.9%. The cows showed maturity age at 40 months, which may have occurred because they were raised in natural farming conditions. In Pantaneiro cows reared in extensive systems only on natural pastures, the use of ultrasound is not effective to estimate the curve of muscular development, perhaps because this breed was not selected for weight gain.

  17. A large blood pressure-raising effect of nitric oxide synthase inhibition in humans

    In experimental animals, systemic administration of nitric oxide synthase (NOS) inhibitors causes large increases in blood pressure that are in part sympathetically mediated. The aim of this study was to determine the extent to which these conclusions can be extrapolated to humans. In healthy normotensive humans, we measured blood pressure in response to two NOS inhibitors, NG-monomethyl-L-arginine (L-NMMA) and NG-nitro-L-arginine methyl ester (L-NAME), the latter of which recently became available for use in humans. The major new findings are 3-fold. First, L-NAME produced robust increases in blood pressure that were more than 2 times larger than those previously reported in humans with L-NMMA and approximated those seen in experimental animals. L-NAME (4 mg/kg) raised mean arterial pressure by 24+/-2 mm Hg (n=27, P<0.001), whereas in subjects who received both inhibitors, a 12-fold higher dose of L-NMMA (50 mg/kg) raised mean arterial pressure by 15+/-2 mm Hg (n=4, P<0.05 vs L-NAME). Second, the L-NAME-induced increases in blood pressure were caused specifically by NOS inhibition because they were reversed by L-arginine (200 mg/kg, n=12) but not D-arginine (200 mg/kg, n=6) and because NG-nitro-D-arginine methyl ester (4 mg/kg, n=5) had no effect on blood pressure. Third, in humans, there is an important sympathetic component to the blood pressure-raising effect of NOS inhibition. alpha-Adrenergic blockade with phentolamine (0.2 mg/kg, n=9) attenuated the L-NAME-induced increase in blood pressure by 40% (P<0.05). From these data, we conclude that pharmacological inhibition of NOS causes large increases in blood pressure that are in part sympathetically mediated in humans as well as experimental animals.

  18. Passive Leg Raising Correlates with Future Exercise Capacity after Coronary Revascularization.

    Shu-Chun Huang

    Full Text Available Hemodynamic properties affected by the passive leg raise test (PLRT reflect cardiac pumping efficiency. In the present study, we aimed to further explore whether PLRT predicts exercise intolerance/capacity following coronary revascularization. Following coronary bypass/percutaneous coronary intervention, 120 inpatients underwent a PLRT and a cardiopulmonary exercise test (CPET 2-12 days during post-surgery hospitalization and 3-5 weeks after hospital discharge. The PLRT included head-up, leg raise, and supine rest postures. The end point of the first CPET during admission was the supra-ventilatory anaerobic threshold, whereas that during the second CPET in the outpatient stage was maximal performance. Bio-reactance-based non-invasive cardiac output monitoring was employed during PLRT to measure real-time stroke volume and cardiac output. A correlation matrix showed that stroke volume during leg raise (SVLR during the first PLRT was positively correlated (R = 0.653 with the anaerobic threshold during the first CPET. When exercise intolerance was defined as an anaerobic threshold < 3 metabolic equivalents, SVLR / body weight had an area under curve value of 0.822, with sensitivity of 0.954, specificity of 0.593, and cut-off value of 1504·10-3mL/kg (positive predictive value 0.72; negative predictive value 0.92. Additionally, cardiac output during leg raise (COLR during the first PLRT was related to peak oxygen consumption during the second CPET (R = 0.678. When poor aerobic fitness was defined as peak oxygen consumption < 5 metabolic equivalents, COLR / body weight had an area under curve value of 0.814, with sensitivity of 0.781, specificity of 0.773, and a cut-off value of 68.3 mL/min/kg (positive predictive value 0.83; negative predictive value 0.71. Therefore, we conclude that PLRT during hospitalization has a good screening and predictive power for exercise intolerance/capacity in inpatients and early outpatients following coronary

    The use of solar electric propulsion to raise a high-power communication satellite from a low altitude, inclined circular orbit of the geosynchronous orbit is evaluated. Since the satellite ascends through the high intensity radiation belts, the power available from the solar array and therefore to the ion thrusters degrades. The performance of the solar electric stage in combination with the thrust augmented Thor/Delta launch vehicle is evaluated for two thrust steering programs. The transfer times and solar array requirements are presented for total geosynchronous payloads from 450 to 1100 kg.

    International Nuclear Information System (INIS)

    The public is concerned about how the shipping and handling of radioactive materials affects them and their environment. Through exhibit showings doing professional education conferences and smaller, focussed workshops, the United States Department of Energy (DOE) has found teachers and students to be an especially interested audience for hazardous and radioactive materials transportation information. DOE recognizes the importance of presenting educational opportunities to students about scientific and societal issues associated with planning for and safely transporting these types of materials. Raising students' and educators' awareness of hazardous and radioactive materials transport through creative classroom materials and exhibits may help them make informed decisions as adults about this often controversial and difficult issue

    Full Text Available Mothers are viewed as the people who are raising future citizens of Canada; therefore, their parenting practices are being targeted for intervention by civic organizations funded by the state. In this article, I argue that modernity narratives and neoliberalism approaches to mothering inform parenting education classes for Somali refugee women to Canada. Thus, Somali women are often seen as victims. Stereotyped identities conceal their social and historical agency. This research draws on 15 individual interviews with Somali mothers and participant- observation in two parenting education classes in Canada.

  9. Technique improvement of thoracoabdominal CT scan for patients with arm-raising disability

    International Nuclear Information System (INIS)

    Objective: To explore a new scanning technique to reduce and avoid image artifacts of thoracoabdominal CT and improve image quality for patients who cannot raise their arms. Methods: Sixty-one patients with arm-raising disability between March 2004 and May 2009 were enrolled in the study. Thirty-one cases before June 2007 were scanned with their arms beside their body (control group), 30 cases after June 2007 were scanned with their arms shifting to different imaging planes of the spine (study group), and another 30 patients who can raising their arms were taken as routine group. The images artifacts were blindly evaluated by 5-points scale (severe, less severe, moderate, minimum and no artifact) by 2 experienced CT technologists and one radiologist and compared between the three groups (X2 test). CT values and its noise of the liver with or without artifact of the three groups were measured and analyzed by one-way ANOVA test. Results: In the control group, 11 cases had severe, 15 cases had less severe, 5 cases had moderate. In the study group, 6 cases had moderate, 15 cases had minimum, 9 cases had no artifact. In the routine group, 8 cases minimum and 22 cases had no artifact. Image quality was significantly improved in the study group compared to the conventional group where X2=95.32 and P<0.01. CT value and the noise of the liver without artifact were (54.5 ± 3.0) HU and 10.7 ± 2.4 in the control group, (52.0 ± 3.5) HU and 10.7 ± 0.5 in the study group, (53.7 ± 3.1) HU and 9.9 ± 0.5 in the routine group, respectively. CT value and noise of the liver with artifact were (41.7 ± 8.4) HU and 17.9 ± 2.6 in control group, (53.1 ± 6.9) HU and 11.0 ± 0.7 in the study group, (54.1 ± 2.4) HU and 9.9 ± 0.5 in the routine group, respectively. The CT value and its noise variation with artifact were significantly higher in the control group than the study group and the control group, where F=36.352, 235.848, respectively and P<0.01.

We find that raising the ERA increased employment by 9.75 percentage points among affected men and by 11 percentage points among affected women. The reforms had large spillover effects on the unemployment insurance program but negligible effects on disability insurance claims. Specifically, unemployment increased by 12.5 percentage points among men and by 11.8 percenta...

    A healthy and productive life depends upon the balance between work, leisure, and activities of daily living. Gaining or regaining that balance is a core concept within occupational therapy. Raising a child with special needs is one factor that challenges parents in achieving a balance. The purpose of this research was to describe factors that affect the leisure occupations of these parents. A qualitative approach was used in which in-depth interviews and the adapted Barth Time Construction were administered to four married couples that were raising children with Down syndrome who were between seven and nine years of age. Data was examined through content analysis. Results indicated that the parents of children with Down syndrome had limitations in time available for leisure, changes in types of leisure engaged in, and an increase in planning for leisure activities. Despite overall satisfaction with the manner in which they allocated their time, parents frequently noted the potential benefits of incorporating more leisure into their daily lives. Limitations of the study include type and size of sample.

    Humans form impressions of others by associating persons (faces) with negative or positive social outcomes. This learning process has been referred to as social conditioning. In everyday life, affective nonverbal gestures may constitute important social signals cueing threat or safety, which therefore may support aforementioned learning processes. In conventional aversive conditioning, studies using electroencephalography to investigate visuocortical processing of visual stimuli paired with danger cues such as aversive noise have demonstrated facilitated processing and enhanced sensory gain in visual cortex. The present study aimed at extending this line of research to the field of social conditioning by pairing neutral face stimuli with affective nonverbal gestures. To this end, electro-cortical processing of faces serving as different conditioned stimuli was investigated in a differential social conditioning paradigm. Behavioral ratings and visually evoked steady-state potentials (ssVEP) were recorded in twenty healthy human participants, who underwent a differential conditioning procedure in which three neutral faces were paired with pictures of negative (raised middle finger), neutral (pointing), or positive (thumbs-up) gestures. As expected, faces associated with the aversive hand gesture (raised middle finger) elicited larger ssVEP amplitudes during conditioning. Moreover, theses faces were rated as to be more arousing and unpleasant. These results suggest that cortical engagement in response to faces aversively conditioned with nonverbal gestures is facilitated in order to establish persistent vigilance for social threat-related cues. This form of social conditioning allows to establish a predictive relationship between social stimuli and motivationally relevant outcomes. PMID:25054341

    Laryngeal cancer has poorer outcomes if diagnosed at a later stage. Improving awareness could encourage earlier presentation and improve outcomes. This study aimed to evaluate a public engagement campaign targeted at raising awareness of laryngeal cancer. An epidemiological study identified high-risk populations in the region. A target population as well as a matched control population was selected. A cancer awareness survey combined with focus groups guided the design of a 3-month multimedia campaign. The survey was repeated post-campaign to evaluate the campaign effectiveness. The study identified populations with the highest rates of laryngeal cancer and late stage disease at presentation. The surveys performed revealed a limited effect of the multimedia campaign in raising awareness of the signs and symptoms of laryngeal cancer. Recall of the campaign also faded rapidly. This is the first public awareness campaign aimed at laryngeal cancer carried out in the UK. The results suggest that short-term campaigns have a limited effect and a more prolonged approach should be considered. PMID:26573156

    Whole genome and exome sequencing (WGS/WES) techniques raise hope for a new scale of diagnosis, prevention, and prediction of genetic conditions, and improved care for children. For these hopes to materialize, extensive genomic research with children will be needed. However, the use of WGS/WES in pediatric research settings raises considerable challenges for families, researchers, and policy development. In particular, the possibility that these techniques will generate genetic findings unrelated to the primary goal of sequencing has stirred intense debate about whether, which, how, and when these secondary or incidental findings (SFs) should be returned to parents and minors. The debate is even more pronounced when the subjects are adolescents, for whom decisions about return of SFs may have particular implications. In this paper, we consider the rise of "genomic citizenship" and the main challenges that arise for these stakeholders: adolescents' involvement in decisions relating to return of genomic SFs, the types of SFs that should be offered, privacy protections, and communication between researchers and adolescents about SFs. We argue that adolescents' involvement in genomic SF-related decisions acknowledges their status as valuable stakeholders without detracting from broader familial interests, and promotes more informed genomic citizens.

    Full Text Available The paper aimed to analyze the economic efficiency in two farms dealing with Carabasa Breed raising as follows:Farm1-86 sheep flock, of which 62 ewes, producing in average 146 liters milk/head/year and Farm 2-297 sheepstock, of which 255 ewes, with 140 liters/head milk yield. Economic efficiency was comparatively analyzed basedon: gross product, production cost, variable and fixed cost, gross margin, profit, profit rate, farm economic size. Theboth farms registered profit, but Farm 2, the largest one taking into account the number of sheep, recorded a highereconomic efficiency: 1.5 lambs/ewe, 22.50 kg cottage cheese/ewe, 1.17 Easter lambs/ewe, Euro 148 feedingcost/sheep, Euro 0.30/liter milk cost, Euro 233 income/ewe, Euro 61 profit/ewe, Euro 68 gross margin/ewe and a35.55% profit rate. With Euro 17,274 profit at farm level, Farm 2 was considered a commercial middle sized farm,ESU 7.19 and Farm 1 a very small farm, ESU 1.04. As a conclusion, breeders raising Carabasa Breed, an excellentbiological resource for milk and meat for Romanian sheep farming, have to increase farm size in order to go up theprofitability and competitiveness of their farms.

    The expansions or the compressions of the ideal gas in the quasi-static Carnot cycle, can be performed (on adiabatic or isothermal way) by slowly increasing or decreasing the external pressure by means of small weights acting on the piston of the vessel containing the gas. We call them shortly the ``driving weights'' (dw). Let N be their number, a large one. To determine the work performed by the ideal gas in the cycle the ``driving weights'' must be handled carefully. If we let them move on-off the piston only horizontally, their vertical motions will be due only to the gas. Here we show that, at the end, while some of them will have moved down (will have negative raising) the remaining ones (the majority) will have moved up (will have positive raising) so that the total work performed by the ideal gas equals the total variation of the gravitational potential energy of the ``driving weghts''. The cycle is performed in 2N time-steps. For each step t_i, with i in 1,..,2N, we give H(t_i), and DH(t_{i-1},t_i), r...

    Migratory birds can use a variety of environmental cues for orientation. A primary calibration between the celestial and magnetic compasses seems to be fundamental prior to a bird's first autumn migration. Releasing hand-raised or rescued young birds back into the wild might therefore be a problem because they might not have established a functional orientation system during their first calendar year. Here, we test whether hand-raised European robins that did not develop any functional compass before or during their first autumn migration could relearn to orient if they were exposed to natural celestial cues during the subsequent winter and spring. When tested in the geomagnetic field without access to celestial cues, these birds could orient in their species-specific spring migratory direction. In contrast, control birds that were deprived of any natural celestial cues throughout remained unable to orient. Our experiments suggest that European robins are still capable of establishing a functional orientation system after their first autumn. Although the external reference remains speculative, most likely, natural celestial cues enabled our birds to calibrate their magnetic compass. Our data suggest that avian compass systems are more flexible than previously believed and have implications for the release of hand-reared migratory birds.

    To feed the increasing world population, more food needs to be produced from agricultural land systems. Solutions to produce more food with fewer resources while minimizing adverse environmental and ecological consequences require sustainable agricultural land use practices as supplementary to advanced biotechnology and agronomy. This review paper, from a land system perspective, systematically proposed and analyzed three interactive strategies that could possibly raise future food production under global change. By reviewing the current literatures, we suggest that cropland expansion is less possible amid iferce land competition, and it is likely to do less in increasing food production. Moreover, properly allocating crops in space and time is a practical way to ensure food production. Climate change, dietary shifts, and other socio-economic drivers, which would shape the demand and supply side of food systems, should be taken into consideration during the decision-making on rational land management in respect of sustainable crop choice and allocation. And ifnally, crop-speciifc agricultural intensiifcation would play a bigger role in raising future food production either by increasing the yield per unit area of individual crops or by increasing the number of crops sown on a particular area of land. Yet, only when it is done sustainably is this a much more effective strategy to maximize food production by closing yield and harvest gaps.

  3. A RAISED PANEL METHOD BASED ON NURBS FOR FREE-SURFACE POTENTIAL FLOWS WITH FORWARD SPEED

    2003-01-01

    A raised panel method based on NURBS (Non-Uniform Rational B-Splines) for free-surface flows with forward speed is presented. In this generalized panel method, NURBS are employed to represent the body geometry, disturbed free surface, and to express the unknown source strength distribution, on the body surface and above the free surface. Compared with common higher-order panel methods, it has no need of adopting local coordinates. NURBS make the geometry representation of the body shape and the wave pattern more precise. Raised panels above the free surface produce less numerical dispersion error, need less CPU consumption and are helpful and combined with collocation-point shifting up-stream, can satisfy the radiation condition numerically. By using continuous and discrete Fourier analysis, numerical errors of this method are discussed and a general expression for the errors of numerical damping and dispersion, including the effects of the vertical distance of singularities to the free surface, the order of singularity distribution represented by B-splines in panels, and collocation-point shifting is derived.

    Market based instruments (MBIs) for maritime transport have the potential to reduce emissions while at the same time raising funds for climate policies in developing countries. GHG emissions from international aviation and maritime transport accounted for approximately 5% of global anthropogenic emissions in 2005 and are rising rapidly. There is a clear need to address these emissions in order not to undermine policies for mitigating land based emissions. Developing countries need financial support to carry out climate policies, both adaptation and mitigation. The UN Framework Convention on Climate Change (UNFCCC) makes policies by developing countries conditional on climate finance. In the current economic and financial circumstances, there is a need for new sources of finance. The governance of such MBIs should ensure that they are neither an international tax nor require hypothecation of fiscal revenues, while they should provide new and additional finance. MBIs which are in fact an international tax would not be politically feasible, and likewise hypothecation would be opposed by many states. This report finds that an emissions trading scheme (ETS) can satisfy these criteria, provided that: (1) it transfers a share of allowances directly to developing countries in order to ensure there is no net incidence on them; developing countries could auction these allowances in order to raise revenue; (2) it transfers allowances to the Green Climate Fund to support climate policies; auctioning these allowances would provide revenues for the Fund; (3) it transfers allowances to IMO or another organisation in order to finance fuel-efficiency improvements in international transport.

  5. Raising the Dead without a Red Sea-Dead Sea project? Hydro-economics and governance

    2011-04-01

    Full Text Available Seven decades of extractions have dramatically reduced Jordan River flows, lowered the Dead Sea level, opened sink holes, and caused other environmental problems. The fix Jordan, Israel, and the Palestinians propose would build an expensive multipurpose conveyance project from the Red Sea to the Dead Sea that would also generate hydropower and desalinate water. This paper compares the Red-Dead project to alternatives that may also raise the Dead Sea level. Hydro-economic model results for the Jordan-Israel-Palestinian inter-tied water systems show two restoration alternatives are more economically viable than the proposed Red-Dead project. Many decentralized new supply, wastewater reuse, conveyance, conservation, and leak reduction projects and programs in each country can together increase economic benefits and reliably deliver up to 900 MCM yr−1 to the Dead Sea. Similarly, a smaller Red-Dead project that only generates hydropower can deliver large flows to the Dead Sea when the sale price of generated electricity is sufficiently high. However, for all restoration options, net benefits fall and water scarcity rises as flows to the Dead Sea increase. This finding suggests (i each country has no individual incentive to return water to the Dead Sea, and (ii outside institutions that seek to raise the Dead must also offer countries direct incentives to deliver water to the Sea besides building the countries new infrastructure.

    Full Text Available Background: Chronic low back pain is a common problem in the present time. It is commonly associated with altered mechanical tension in the peripheral nerves as tested by straight leg raising or slump tests. These maneuvers are used for treatment of such disorders. Both the straight leg raise and slump stretching techniques have been found to be beneficial in the treatment of low back pain with distal symptoms. A comparison of the two techniques will determine if one technique is better than the other. Also, it will add to the evidence for their effectiveness in managing symptoms in patients with low back pain. Objective: To evaluate the comparative effectiveness of straight leg raise and slump stretching on pain and range of passive straight leg raise in subjects with low back pain. Methods and measures: 50 patients with low back pain, satisfying the inclusion and exclusion criteria were randomly assigned to three groups. Group 1 was the straight leg raise group (n=15. Group 2 was the slump group (n=13. Group 3 was the control group (n=12. Baseline measurements of pain intensity as measured by the Numeric Pain Rating Scale (NPRS and range of passive straight leg raise (PSLR were taken. Group 1 received 6 sessions of straight leg raise stretching and lumbar stabilization exercises. Group 2 received 6 sessions of slump stretching and lumbar stabilization exercises. Group 3 received 6 sessions of lumbar stabilization exercises only. Statistical analysis: Paired t-test was used for within group analysis of NPRS and PSLR. ANOVA followed by post hoc analysis was employed for between group comparisons. Results: No significant difference was found in NPRS between straight leg raise and slump groups (p > 0.05 while they differed significantly in PSLR (p < 0.05. Both the groups showed significantly better results in PSLR when compared to the control group (P<0.05. Statistically significant improvements were found in all the 3 groups for both the outcome

    Full Text Available Purpose. The study was aimed at raising young-of-the-year European grayling and improving the industrial technology with the use of specialized artificial feeds. Methodology. The work on raising young-of-the-year European grayling was carried out in 2014 at the fish hatchery “Lopushno”, Chernivtsi region, during five months (May – September. YOY were obtained from 22 age-3–4 brood fish, which were kept in ponds of the natural reserve “Synevir”. Culture-biological parameters of brood fish were determined based on Pravdin (1966 method for salmonids. To avoid traumatization of fish, they were kept in the anesthetic “Propiscin” before the collection of sexual products. The condition factor was determined by Fulton’s formula. Findings. The mean weight of brood fish used for spawning was 110 g with the mean body length of 22 cm. Fulton’s condition factor of European grayling was: 1.1 in females and 1.0 in males. Feeding of larvae was as follows: starting feeds — live feeds (Cyclops, Moina, then the alternation of live feeds and a specialized starting feed for 30 days, and the artificial feed after. Raising European grayling from larvae to young-of-the-year was carried out in trays of different sizes from 0.5 m2 to 4.5 m2, water level in trays was increased according to fish growth from 20 cm to 42 cm. Water supply was 60 L/min, thus the rate of water exchange was from 0.5 to 1.7 times/hour that corresponded to technical norms for salmonids. Mean weight of the young-of-the-year on September 10 was 17.1 g, mean length was 11.8 cm. Originality. Consists in the comprehensive assessment and development of an integral mechanism of scientific principles and methodical recommendations on artificial reproduction of European grayling. Practical value. The results of the work will be used for the works on the reproduction of valuable fish species in aquaculture facilities of the Carpathian region.

  9. Reduction of emissions from Brazilian cattle raising and the generation of energy: Intensification and confinement potentials

    International Nuclear Information System (INIS)

    The identification of the main sources of anthropic greenhouse gas emissions (GHG) associated with the mitigation and removal of these emissions has become an important instrument in the attenuation of the climatic changes predicted by the IPCC. The largest emission source in Brazil is forest conversion. This land use change has always had a strong relationship with the expansion of agriculture, an activity of great importance in the country, which has the largest commercial cattle herd in the planet. Following the considerable reduction in emissions from deforestation, agriculture has been since 2010 the most important source (MCTI (Ministério da Ciência, Tecnologia e Inovação), 2013. Brasília: Ministério daCiência, Tecnologia e Inovação, Brasil). Seeking to discover the possibilities of altering the emissions profile in the agricultural sector, four scenarios were developed related to how this is dealt with in the beef cattle sector, calculating the potential removal of carbon from the atmosphere through natural regeneration of biomes. The results suggest that picketing and rotation scenario has the greatest potential, with a carbon reduction of 17.7 Gt CO2eq, while the shared raising with grain legumes scenario has the lowest calculated reduction potential of 7.1 Gt CO2eq was calculated. The animal confinement scenario had an intermediary reduction potential of 8.3 Gt CO2eq. The mosaic of methods scenario, in which it is attempted to simulate the parallel adoption of the measures proposed in all other scenarios, had a reduction potential of 13.1 Gt CO2eq. In the scenarios where animal confinement occurs, the treatment of waste with biodigestion allows the generation of biogas and biofertilizers, contributing to an increase in the potential carbon reduction. - Highlights: • We identify one main source of anthropic GHG in Brazil after forest conversion (deforestation), the beef cattle raising. • Four scenarios to mitigate emissions from cattle raising

    Organic agriculture is developing worldwide, and organic rabbit production has developed within this context. It entails raising rabbits in moving cages or paddocks, which enables them to graze grasslands. As organic farmers currently lack basic technical information, the objective of this article is to characterize herbage intake, feed intake and the growth rate of rabbits raised on grasslands in different environmental and management contexts (weather conditions, grassland type and complete feed supplementation). Three experiments were performed with moving cages at an experimental station. From weaning, rabbits grazed a natural grassland, a tall fescue grassland and a sainfoin grassland in experiments 1, 2 and 3, respectively. Rabbit diets were supplemented with a complete pelleted feed limited to 69 g dry matter (DM)/rabbit per day in experiment 1 and 52 g DM/rabbit per day in experiments 2 and 3. Herbage allowance and fiber, DM and protein contents, as well as rabbit intake and live weight, were measured weekly. Mean herbage DM intake per rabbit per day differed significantly (P<0.001) between experiments. It was highest in experiment 1 (78.5 g DM/day) and was 43.9 and 51.2 g DM/day in experiments 2 and 3, respectively. Herbage allowance was the most significant determinant of herbage DM intake during grazing, followed by rabbit metabolic weight (live weight0.75) and herbage protein and fiber contents. Across experiments, a 10 g DM increase in herbage allowance and a 100 g increase in rabbit metabolic weight corresponded to a mean increase of 6.8 and 9.6 g of herbage DM intake, respectively. When including complete feed, daily mean DM intakes differed significantly among experiments (P<0.001), ranging from 96.1 g DM/rabbit per day in experiment 2 to 163.6 g DM/rabbit per day in experiment 1. Metabolic weight of rabbits raised on grasslands increased linearly over time in all three experiments, yielding daily mean growth rates of 26.2, 19.2 and 28.5 g/day in

    The dynamics of the green space in urban areas are key components for the urban environment monitoring options and of the urban planning strategies. In the European Union, specific regulations provide the quantitative measures for green space areas necessary for each inhabitant of a city. To assess the situation in the case of Bucharest, we used the multitemporal analysis of remotely sensed imagery based on Landsat archive available. This enabled us to characterize the possibility to monitor and assess the changes in the vegetation cover over a quarter of a century, and raised a series of issues based on the remote sensing observations and image processing. The quantitative assessment of the green spaces is further developed into proposals related to the green space provisions in urban planning, but also revisions of the quantitative measures used in regulations.

    Grandparent caregivers are vital to the survival of grandchildren who are orphaned and who have been affected by HIV/AIDS. The purpose of this qualitative study was to understand the meaning of HIV as a disease among grandparents raising grandchildren orphaned by HIV/AIDS in northern Vietnam and to gain insight into how this understanding affected grandparents' relationships and health-seeking decisions. Results indicated that grandparents had knowledge deficits about the biomedical aspects of the disease and often hid their grandchildren's HIV status or preferred not to seek testing. Effective interventions must address stigma reduction, family relationships, and access to health care to increase testing and treatment of grandchildren. PMID:27218419

NAI was acknowledged by 91.3 per cent (95 per cent confidence interval, 88.2 to 93.9 per cent) of the 404 respondents who returned questionnaires, of whom 48.3 per cent (95 per cent confidence interval, 43.4 to 53.1 per cent) had either suspected or seen NAI. Four hundred and forty-eight cases were documented, predominantly in dogs (243) and cats (182). Factors either raising suspicion, or facilitating recognition, of NAI included: implication of a particular person, features of the history, referral agency involvement, behaviour of the owner and/or the animal, nature of the injuries, and socioeconomic class of owners. Additionally, sexual abuse and suspected cases of Munchausen syndrome by proxy were recorded.

  14. Bog discharge from different viewpoints: comparison of Ingram's theory with observations from an Estonian raised bog

    Raised bogs are typically dome shaped and have a groundwater level located close to the soil surface. Besides their typical dome shape, these peatlands are often characterized by a pronounced surface topography consisting of pools, wet depressions (hollows), stretches of Sphagnum species (lawns), drier mounds (hummocks) and higher drier areas with terrestrial vegetation (ridges). These peat bodies drain laterally by gravity to adjacent areas with lower groundwater levels. The integrity of these bogs is only ascertained when water is stored in the peat body in periods of precipitation deficit and efficiently removed in wet periods. This is realized by the fact that the bog's top layer, often called acrotelm, has a variable hydraulic conductivity. In response to precipitation its hydraulic conductivity increases, whereas, under evaporative demand the water table lowers and therefore also the hydraulic conductivity decreases. Ingram proposed a model based on the Dupuit-Forchheimer approximation for Darcy's law that assumes vertical flow is negligible, and the slope of the water table is equal to the hydraulic gradient. U- Hm2- K = L2 (1) where U is net recharge (P-ET), K is horizontal hydraulic conductivity, Hm is hydraulic head above a flat bottom at the centre of the bog, L is half the width of the bog along the cross section. This model incorporates the assumption that all net rainfall reaching the water table will be discharged to the stream. Ingram's model does not consider local heterogeneities in surface topography, like pool-ridge patterns. We hypothesize that under drier conditions it is likely that pool-ridge patterning will inhibit water from flowing along the surface gradient. Under wet conditions, however, pools can become connected and water can move through the upper highly permeable layer of ridges. In this study, we investigated the influence of ridge-pool patterning on the horizontal water flow through a raised bog and compared it with Ingram

  15. Radioactivity studies on farm raised and wild catfish produced in Mississippi, USA

    International Nuclear Information System (INIS)

    To understand the contribution of radiation dose to human from consumption of catfish, a comparative radiological assessment study was performed on farm and river raised fish. Gamma spectroscopic analyses of catfish indicated the presence of isotopes of 40K, 226Ra, and 228Ra with activity values of 99.4 ± 14.5, 0.41 ± 0.05, and 0.89 ± 0.08 Bq kg-1 respectively in farm catfish and 101 ± 15.7, 0.47 ± 0.05, and 0.97 ± 0.050 Bq kg-1 respectively in river catfish. The measured activities in two sets of samples were statistically compared using a two-tailed t test at 95 % confidence interval and results indicated that activities of 226Ra and 228Ra were significantly different.

    In light of the growing emphasis on community engagement in the literature on renewable energy planning, and given the acknowledgement of the complexity of community engagement as a concept, we conducted an empirical review of practice relating to community engagement with onshore wind farms...... in the UK, exploring what is actually happening in terms of community engagement relating to onshore wind farms, and examining the rationales underpinning approaches to community engagement. We found that a wide range of engagement methods are being used in relation to onshore wind farms across the UK......-hierarchical classification of community engagement approaches: awareness raising; consultation and empowerment. This provides a useful tool for reflecting on practices and rationales of community engagement. By considering the three approaches non-hierarchically, this model allows for an examination of how such rationales...

    Full Text Available The maintenance of animals in captivity is one of the many ways of species preservation and allows studies that are often unattainable under natural conditions. Primate’s behavior and ecology studies supply tools for the development of conservation and management strategies. Consequently, the current research aimed to describe the patterns of behavior of a capuchin monkey, Sapajus nigritus, group raised in captivity at the Biodiversity Center of Associação Esportiva e Recreativa at Ipatinga, MG, Brazil. The Scan Sample was used with five minutes intervals. Ad libitum and Focal Animal were the complementary sampling. Twenty-three behavioral categories were recorded; this is considered average when compared to other ethograms. The behavioral class with greater prominence was foraging, however the different categories of behavior suggest a complex capacity of intra-specific interaction. The information serves as basic tools for the formulation of conservation strategies, management and to the comprehension of ecological interactions.

    How high the temperature of a liquid be raised beyond its boiling point without vaporizing (known as the limit of superheat) is an interesting subject of investigation. A new method of finding the limit of superheat of liquids is presented here. The superheated liquids are taken in the form of drops suspended in visco elastic gel. The nucleation is detected acoustically by a sensitive piezo-electric transducer, coupled to a multi channel scaler and the nucleation is observed as a funtion of time and with increase of temperature. The limit of superheat measured by the present method supersedes all other measurements and theoretical predictions in reaching closest to the critical temperature and warrants improved theoretical predictions.

    Chytridiomycosis (Bd) is contributing to amphibian extinctions worldwide but has so far not been detected in Madagascar. The high likelihood for Bd to spread to the island and efface this amphibian diversity and endemism hotspot requires respective conservation policies to be developed. Bd could be introduced by the large number of tourists that visit protected areas; therefore, increasing awareness among tourists and encouraging them to participate in safety measures should be a priority conservation action. However, concerns have been raised that tourists would not be able to distinguish between an amphibian disease harmless to humans and emerging diseases that would imply a danger for human health, invoking a negative image of Madagascar as an ecotourism destination. We evaluated whether informing tourists about this infectious animal disease would cause health scare and diminish trip satisfaction. Based on 659 respondents we found that most ecotourists favored to be informed about Bd and were proactive about participating in prevention measures, refuting previous concerns. PMID:20517634

    2015-08-01

    This article examines the interrelations between psychology and feminism in the work of feminist psychologists and radical feminists in Toronto in the early 1970s. For Canadian feminist psychology as well as for second-wave activism, Toronto was a particular hotspot. It was the academic home of some of the first Canadian feminist psychologists, and was the site of a lively scene of feminists working in established women's organizations along with younger socialist and radical feminists. This article analyzes the interrelations of academic feminist psychology and feminist activism by focusing on consciousness-raising, a practice that promised to bridge tensions between the personal and the political, psychological and social liberation, everyday knowledge and institutionalized knowledge production, theory and practice, as well as the women's movement and other spheres of women's lives.

    Full Text Available The first purpose of this study was to investigate the effect of consciousness-raising (C-R activities on learning grammatical structures by Iranian EFL learners. The second one was to investigate the effect of gender through C-R activities and tasks. Finally, this study wanted to investigate the Iranian students’ attitudes toward learning English prior to and after applying the C-R activities. An attitude questionnaire was use to investigate the participants' attitudes toward learning English before and after applying C-R activities. Data analysis indicated that using C-R activities in is significantly more effective than the traditional approaches. Regarding gender, male outperformed females. Therefore, it is recommended that other teachers consider C-R activities as useful options in teaching other aspects of language.  Based on the statistics and findings, Iranian students’ attitudes toward learning English language were not much different prior to and after applying C-R activities.

    2012-01-01

    Policymakers have proposed increases to the early eligibility age (EEA) and/or full retirement age (FRA) to address increasing life expectancy and Social Security solvency issues. This analysis uses the Social Security Administration's Modeling Income in the Near Term, version 6 (MINT6) model to compare three retirement-age increases suggested by the Social Security Advisory Board: increase the gap between the EEA and FRA by raising only the FRA, increase both the EEA and FRA to maintain a 4-year gap between them, and increase both the EEA and FRA to maintain a 5-year gap between them. Although all three options would improve system solvency by similar proportions, their effect on individual beneficiaries in the future would vary. Benefit reductions are greater under the proposals with more months between the EEA and FRA, while the option that maintains a 4-year gap results in benefit increases for some beneficiaries compared with current law.

    Charles H. Earnshaw

    2016-01-01

    Full Text Available A Caucasian male in his early twenties suffering from treatment resistant schizophrenia was started on clozapine. After three days he developed tachycardia, a common side effect of clozapine induction. He had one temperature spike (38.9°C on day ten after induction but remained clinically well. An ECG and blood tests were normal. Due to persistent tachycardia and an episode of collapse whilst seated on day 12, he was admitted to hospital for further investigation. A diagnosis of myocarditis was confirmed as a result of elevated cardiac enzyme levels and an echocardiogram. Following withdrawal of clozapine, supportive management, and initiation of cardiac medication, the patient made a successful recovery. He will be followed up with the cardiology team to ensure that his heart function returns to normal. Given the incidence of clozapine-induced myocarditis, the associated mortality risk, and diagnostic difficulties, this case raises questions about whether a formal system for identifying myocarditis should be adopted.

    Roberto FRATINI

    2014-07-01

    Full Text Available This study aims to highlight the importance of a cattle race native in an area of the territory of Tuscany. The Maremmana breed is a valuable breed raised in the pastures that stretch between southern Tuscany and northern Lazio. A sample of 12 farms was analyzed through direct interview, carried out at the farm. The farms surveyed implement organic farming, according to precise rules. The aspect that mostly catches in the interviews is that the only livestock activity is not sufficient for economic development of this rural area; in fact most of the farms perform multi-functional, practicing agritourism activities. In terms of remuneration of the factors of production used in animal husbandry it seems that especially farms with few animals require the integration of agricultural income with other business activities.

    The Tokai 1 gas cooled reactor 166 MW(e) reactor went into service in 1966 and was shut down in 1998. Since that date the Japan Atomic Power Company, the owner of the plant has been planning and implementing an ambitious programme which will lead to the first Level 3 decommissioning of a commercial power reactor in Japan. JPC's basic strategy is to manage and perform the decommissioning work with in-house resources, calling on the support of specialist companies as and when required. This paper describes the JPC programme and in particular the dismantling of the 4 steam raising units (SRU) which is to be performed using remotely controlled equipment. (authors)

  9. Raising money with tax incentives: an overview of how U.S. tax credits are marketed

    International Nuclear Information System (INIS)

    This article outlines a method for using certain U.S. income tax credits to raise investment capital. With proper structuring, these tax credits can essentially be ''sold'' to outside investors. A project which may not have sufficient income to take advantage of tax benefits, such as the 29 alternative fuel credit, may sell an interest in the project to commercial investors who can use tax credits. The investors provide cash for the project in return for the tax credits, as well as a portion of the income generated by the project. This article outlines how this type of arrangement can be structured and which tax credits are available for ''sale''. It also identifies possible sources of investment money, issues that an investor will likely consider before investing in such a project, and the potential pitfalls of such a project. (author)

    Epigenetic testing is one of the most significant new technologies to provide insight into the behavioral and environmental factors that influence the development and reconfiguration of the human genetic code. This technology allows us to identify structural changes in the genome that occur due to exposure to a wide variety of substances including alcohol, tobacco, and cannabis. The information gained can be used to promote health but it also raises a variety of ethical, legal, and social issues. As society progresses in understanding the epigenetic mechanisms of substance use and addiction, there is an opportunity to use these use this knowledge to enable medical, behavioral, and environmental interventions to alleviate the burden of addiction. This article describes the ethical issues associated with use of epigenetic testing for alcohol, tobacco, and cannabis and the implications of this technology. A further review of the scientific basis for the relevance of epigenetics is found in the accompanying article by Philibert and Erwin in this issue.

    Directory of Open Access Journals (Sweden)

    Anais Thouin

    Full Text Available Leber Hereditary Optic Neuropathy (LHON is an important cause of inherited mitochondrial blindness among young adults. The majority of patients carry one of three mitochondrial DNA (mtDNA point mutations: m.3460G>A, m.11778G>A and m.14484T>C, all of which affect critical complex I subunits of the mitochondrial respiratory chain. LHON is characterised by marked incomplete penetrance, clearly implying that the mtDNA mutation is insufficient on its own to trigger retinal ganglion cell dysfunction and visual loss. In this case series of three affected patients harbouring the m.11778G>A mutation, we provide evidence suggesting that raised intraocular pressure could be a risk factor triggering visual loss in at-risk LHON carriers.

    Rice husks, coffee bean skins, sugar cane bagasse, maize cobs, saw dust and fine charcoal dust were evaluated as filters for the removal of heavy metals (Cu and Zn) from the waste water of swine raising installations. The specific mass, pH and the sum of bases and removable acids were determined to characterize each of the filter materials. Each filtering material was placed in a 100 mm diameter, 600 mm long, PVC column to a height of 500 mm under 12,500 N m(-2) of compression. Chemical and physical analyses were determined on effluent samples collected for each 1.5 l up to a total of 15 l. The organic materials reduced the concentration of sediment solids (> 90%), total solids (up to 33%) and Cu (up to 43.6%) of the inffluent but had little or no effect on Zn concentration.

    Full Text Available This article deals with main issues concerning bilingualism and bilingual first language acquisition (BFLA. A review of the literature is presented on how children learn languages. In addition, this paper summarizes what bilingualism is and addresses how the One-parent One-language (OPOL and the Minority Language at Home (ML@H methods work. The paper includes sample testimonies of Itzel, a three-year-old child, raised with these methods. It also illustrates samples of her code-switching and code-mixing as part of her evolution in bilingual first language acquisition. Based on this evolution, there is some evidence that a child can become bilingual under foreign language conditions. Finally, the article reflects on the decisive role that dedication, consistency and effort have as crucial components to accomplish BFLA.

    1997-05-01

    Bufonid frogs of the genus Atelopus contain two classes of skin toxins, namely the steroidal bufadienolides and the water-soluble tetrodotoxins. Frogs of the Panamanian species Atelopus varius have now been raised in captivity and levels in skin extracts of bufadienolides and of tetrodotoxin-like compounds assessed, using inhibition of [3H]ouabain binding and inhibition of [3H]saxitoxin binding, respectively. Levels of ouabain equivalents, corresponding to bufadienolides, were comparable to those found in wild-caught frogs from the same population in Panama, while tetrodotoxin-like activity was undetectable. The results strongly implicate environmental factors, perhaps symbiotic microorganisms, in the genesis of tetrodotoxins in the skin of frogs of the genus Atelopus, while indicating that the frog itself produces the skin bufadienolides.

    2006-09-01

    This study evaluated the impact of two targeted family sessions focused on driving issues delivered within the context of the Raising Healthy Children project. The Raising Healthy Children project began in the fall of 1993, drawing students in the 1st or 2nd grades from 10 schools. Schools were assigned to an intervention or control condition, and the school-wide, family- and student-focused preventive intervention to address developmentally salient risk and protective factors was delivered during elementary and middle school. The family driving sessions were administered to families in the intervention condition prior to and after teenagers received their driver's license. The first session consisted of a home visit with families designed to help parents and their children improve decision-making skills concerning driving and to develop clear standards and expectations regarding driving-related behavior. A second session, at the time of licensure, was designed to help parents and teens develop a written contract that stated family expectations, a plan for monitoring compliance with these expectations, and consequences for compliance or non-compliance. Consistent with the study's group-randomized design, intervention effects were assessed with multi-level logistic regression models in which students were grouped by their original school assignment. These models assessed specific effects of the driving sessions by adjusting for control variables measured when students were in 8th grade, prior to the driving sessions. Results indicated that students in the intervention group were more likely than students in the control group to report that they had a written driving contract (p = .003, OR = 4.98), and had participated in making the driving rules in the family (p = .025, OR = 1.70). Further, students in the intervention group reported significantly fewer risky behaviors including driving under the influence of alcohol (p = .021, OR = .45) and driving with someone who

  2. Importance of the horse and financial impact of equine trypanosomiasis on cattle raising in Venezuela.

    2013-11-01

    In Venezuela, horses are indispensable for extensive cattle raising, and extensive cattle raising prevails in all regions. This determines the numerical relationship between horses and cattle (r = 0.93) to be relatively constant nationwide. At regional level, the average extension of cattle ranches varies greatly. However, in relation to the area covered by pastures, the numbers of horses (r = 0.95) and cattle (r = 0.93) are relatively uniform nationwide. Water buffalo occupy small fractions of the territory; therefore, their numbers are related to the area of pastures less strongly (r = 0.56). There is no information on the numerical relationship between the numbers of horses and water buffalo. In the Llanos region of the country, equine trypanosomiasis is responsible for a high mortality in horses, causing considerable financial losses to cattle ranches. So far, such losses have not been assessed. For this region, in 2008, it can be calculated that: (1) with no treatment, losses owing to horse mortality caused by this hemoparasitosis would have amounted to US$7,486,000; (2) the diagnosis and treatment of affected horses would have required an investment of US$805,000; and (3) in terms of horses saved, this investment would have resulted in benefit of US$6,232,000. Therefore, for every monetary unit invested, there would be a benefit 7.75 times greater, this ratio being applicable to any year and all regions of the country. It follows that the profitability of investing in the diagnosis and treatment of equine trypanosomiasis is guaranteed.

    Full Text Available BACKGROUND: Asymmetric dimethylarginine (ADMA is a naturally occurring inhibitor of nitric oxide synthesis that accumulates in a wide range of diseases associated with endothelial dysfunction and enhanced atherosclerosis. Clinical studies implicate plasma ADMA as a major novel cardiovascular risk factor, but the mechanisms by which low concentrations of ADMA produce adverse effects on the cardiovascular system are unclear. METHODS AND FINDINGS: We treated human coronary artery endothelial cells with pathophysiological concentrations of ADMA and assessed the effects on gene expression using U133A GeneChips (Affymetrix. Changes in several genes, including bone morphogenetic protein 2 inducible kinase (BMP2K, SMA-related protein 5 (Smad5, bone morphogenetic protein receptor 1A, and protein arginine methyltransferase 3 (PRMT3; also known as HRMT1L3, were confirmed by Northern blotting, quantitative PCR, and in some instances Western blotting analysis to detect changes in protein expression. To determine whether these changes also occurred in vivo, tissue from gene deletion mice with raised ADMA levels was examined. More than 50 genes were significantly altered in endothelial cells after treatment with pathophysiological concentrations of ADMA (2 microM. We detected specific patterns of changes that identify pathways involved in processes relevant to cardiovascular risk and pulmonary hypertension. Changes in BMP2K and PRMT3 were confirmed at mRNA and protein levels, in vitro and in vivo. CONCLUSION: Pathophysiological concentrations of ADMA are sufficient to elicit significant changes in coronary artery endothelial cell gene expression. Changes in bone morphogenetic protein signalling, and in enzymes involved in arginine methylation, may be particularly relevant to understanding the pathophysiological significance of raised ADMA levels. This study identifies the mechanisms by which increased ADMA may contribute to common cardiovascular diseases and

    利用气相色谱质谱联用技术(GC—MS),研究甘肃甘南藏族自治州舍饲(谷物饲料)与放养(天然草料)6月龄蕨麻猪背最长肌中的挥发性风味化合物。两者的差异主要体现在醛类化合物上(舍饲组38.33%,放养组25.19%)。对于来源于美拉德反应的挥发性化合物而言,甲硫基丙醛(呈肉香)与苯并噻唑(呈肉汤味)在舍饲组的含量分别比放养组多23%和122%。舍饲组脂肪氧化产物总相对含量显著高于放养组(P〈0.05),且两组肉样中脂肪氧化产物的种类差异很大。放养组蕨麻猪肉中的萜类含量显著高于舍饲组(P〈0.05)。结果表明,%The volatile compounds in longissimus dorsi muscles from 6 month-old Tibetan miniature pigs raised in feedlot with cereal and on natural pasture from Gannan Tibetan Autonomous Prefecture, Gansu province were investigated by gas chromatography-mass spectrometry (GC-MS). Feedlot-raised and pasture-raised Tibetan miniature pigs mostly varied in their aldehyde contents (38.33% and 25.19%, respectively). Methylthiopropanal (meaty flavor) and benzothiazole (gravy flavor) that can be derived from Mailard reaction in feedlot-raised pork were 23% and 122% more than that in pasture-raised pork, respectively. Lipid oxidation products showed a significant increase in feedlot-raised pork as compared with their pasture-raised pork (P 〈 0.05), and a significant difference in the types of lipid oxidation products was also found. Pasture-raised pork exhibited significantly higher terpene content than feedlot-raised pork (P 〈 0.05). From these results, we concluded that raising methods can affect volatile compounds in pork from Tibetan miniature pig and therefore might affect pork flavor.

  9. Hydrophobicity of 43 potting media: Its implications for raising seedlings in revegetation programs

    Gautam, Resham; Ashwath, Nanjappa

    2012-04-01

    SummaryThe practice of using nursery-raised seedlings is becoming popular in revegetation programs, as this will allow rapid establishment of plants. However, this practice often results in low survival of seedlings in the field, especially in the tropics under rain fed conditions. Part of this can be attributed to hydrophobicity of the media being used in raising the seedlings. Hydrophobicity is the property of potting media which make the media not able to readily absorb water from the surrounding soil once the media dry out. Thus, 41 commercially available potting media and media components and two soil samples (Control) were assessed for hydrophobicity at different moisture levels via Water Droplet Penetration Test (WDPT). At the driest state (oven dried samples), the tested media were classified into five hydrophobicity classes, viz., extremely hydrophobic (WDP time >3600 s, 28% of the tested media), severely hydrophobic (WDP time 600-3600 s, 35%), strongly hydrophobic (WDP time 60-600 s, 21%), slightly hydrophobic (WDP time 5-60 s, 12%) and non-hydrophobic (WDP time increase in moisture content of the media. For example, when samples were oven dried, 63% of the media were found severely to extremely hydrophobic whereas only 14% of the media remained in these categories when moisture content increased to 15%. Significant (P capacity (P adapted from a "Sheen Screen" method suggested that the number of wax degrading bacteria were similar amongst the non-hydrophobic and hydrophobic media. This indicates that the bacterial number may not be an important factor for breaking down hydrophobicity but most likely it is the bacterial activity that plays an important role in this process. Since the majority of the tested potting media were hydrophobic in nature (under dry conditions), and hydrophobicity affects survival of seedlings in the field, we recommend testing of potting media for hydrophobicity as a complimentary requirement of the Australian Standards.

    This study intended to compare the productive performance of three different layer raising systems; conventional cage (CC), barn (BR) and aviary (AV). The AV is welfare bestowed housing that allows free locomotion for birds within the BR. The BR allows bird's free locomotion inside BR but without multilevel structures. Both pullets and cockerels were housed together in both AV and BR, but only pullets in CC. Seventeen weeks old Lohmann Brown Lite (n = 800) pullets were housed in AV during this study. The same age layer pullets were simultaneously assigned to either at CC or BR to compare egg production performance with AV. The duration of experiment was 40 weeks (from 21st to 60th week). There were no remarkable differences in egg production, hen day egg production (HDEP) and average egg weight among three rearing systems. First 20 weeks (phase-1) average HDEP (%) of AV, CC, and BR were 85.9, 88.8, 87.1 and average egg weights (g) were 57.5, 59.9, and 56.9 respectively. Those of the remaining 20 weeks (phase-2) were 87.1, 87.9, 85.5 and 64.2, 63.0 62.1, respectively. Daily feed intakes (122 g, 110 g, 125 g); feed conversion ratio (2.4, 2.1, 2.5) and daily egg mass (53.9 g, 54.4 g, 52.8 g) data from AV, CC, and BR were not influenced significantly by the respective raising systems. Daily feed intake of layers in both AV (124 g) and BR (127 g) tended to be higher than that in CC (113 g) during phase-2. Overall, exterior egg quality (dirty and cracked eggs) in both phases was superior in BR compared with AV and CC, whereas CC generated intermediate results. This study indicated that the HDEP per se in AV and BR were not significantly different from that in CC. The study implied that the facility depreciation cost for AV and cost for increased feed intake in AV compared to CC are believed to be critical to evaluate the cost effectiveness of egg production in AV.

    Organ donation rates have continued to fall seriously short of needs worldwide, with the lowest rates recorded among developing economies. This study seeks to analyze evidence from a developing economy to explore the usefulness of social psychological theory to solve the problem. The study deployed a large survey (n = 10 412) using a convenience sampling procedure targeted at increasing the number of Malaysians registered with the Ministry of Health, Malaysia who are willing to donate organs upon death. Structural equation modeling was deployed to estimate simultaneously the relative influence of cognitive and noncognitive variables on willingness to donate deceased organs. The cognitive factors of donation perception, socioeconomic status and financial incentives, and the noncognitive factors of demography and fear showed a high statistically significant (1%) relationship with willingness to donate organs after death. While financial incentives were significant, cash rewards showed the least impact. Donation perception showed the highest impact, which shows that the development of effective pedagogic programs with simultaneous improvements to the quality of services provided by medical personnel engaged in retrieving and transplanting deceased donor organs can help raise organ donation rates.

    We investigate a non-equilibrium one-dimensional model known as the raise and peel model describing a growing surface which grows locally and has non-local desorption. For specific values of adsorption (ua) and desorption (ud) rates, the model shows interesting features. At ua = ud, the model is described by a conformal field theory (with conformal charge c = 0) and its stationary probability can be mapped onto the ground state of the XXZ quantum chain. Moreover, for the regime ua ⩾ ud, the model shows a phase in which the avalanche distribution is scale-invariant. In this work, we study the surface dynamics by looking at avalanche distributions using a finite-sized scaling formalism and explore the effect of adding a wall to the model. The model shows the same universality for the cases with and without a wall for an odd number of tiles removed, but we find a new exponent in the presence of a wall for an even number of tiles released in an avalanche. New insights into the effect of parity on avalanche distributions are discussed and we provide a new conjecture for the probability distribution of avalanches with a wall obtained by using an exact diagonalization of small lattices and Monte Carlo simulations.

    There have been exponential gains in immuno-oncology in recent times through the development of immune checkpoint inhibitors. Already approved by the U.S. Food and Drug Administration for advanced melanoma and non-small cell lung cancer, immune checkpoint inhibitors also appears to have significant antitumor activity in multiple other tumor types. An exciting component of immunotherapy is the durability of antitumor responses observed, with some patients achieving disease control for many years. Nevertheless, not all patients benefit, and efforts should thus now focus on improving the efficacy of immunotherapy through the use of combination approaches and predictive biomarkers of response and resistance. There are multiple potential rational combinations using an immunotherapy backbone, including existing treatments such as radiotherapy, chemotherapy or molecularly targeted agents, as well as other immunotherapeutics. The aim of such antitumor strategies will be to raise the tail on the survival curve by increasing the number of long term survivors, while managing any additive or synergistic toxicities that may arise with immunotherapy combinations. Rational trial designs based on a clear understanding of tumor biology and drug pharmacology remain paramount. This article reviews the biology underpinning immuno-oncology, discusses existing and novel immunotherapeutic combinations currently in development, the challenges of predictive biomarkers of response and resistance and the impact of immuno-oncology on early phase clinical trial design.

    To engage students of all ages and raise awareness with the general public of seismic activity in Idaho and beyond, we have established a program that starts with building cheap seismometers, followed by learning how to record and analyze seismic events. Every step along the way is performed and documented by the students of Geophysics 201: "Seeing the Unseen". Our class website provides building instructions, part lists, live data, and processed data from earthquakes from around the globe. Three sensors are recording and displayed in a clear case in the lobby of our building, and a touch screen computer with IRIS-provided software on earthquakes completes the setup. As a result, we have increased awareness and interest in seismicity on a number of levels. Boise State University students in the class are hands-on involved. Steady increase in enrollment in this class, and the recent inclusion of the class in the sophomore core curriculum for BSU Geoscience majors indicate the seismology program is working. In addition, BSU students -- not enrolled in GEOPH201 -- who just walk past the display also show great interest: the display is well visited. Off campus, our project draws a lot of attention, and our data is routinely displayed on the Idaho local news. Now we have a three-component system in the lobby of our building, we are reaching out to local K-12 institutions to place our instruments.

  15. Root Raised Cosine (RRC) Filters and Pulse Shaping in Communication Systems

    Cubukcu, Erkin

    2012-01-01

    This presentation briefly discusses application of the Root Raised Cosine (RRC) pulse shaping in the space telecommunication. Use of the RRC filtering (i.e., pulse shaping) is adopted in commercial communications, such as cellular technology, and used extensively. However, its use in space communication is still relatively new. This will possibly change as the crowding of the frequency spectrum used in the space communication becomes a problem. The two conflicting requirements in telecommunication are the demand for high data rates per channel (or user) and need for more channels, i.e., more users. Theoretically as the channel bandwidth is increased to provide higher data rates the number of channels allocated in a fixed spectrum must be reduced. Tackling these two conflicting requirements at the same time led to the development of the RRC filters. More channels with wider bandwidth might be tightly packed in the frequency spectrum achieving the desired goals. A link model with the RRC filters has been developed and simulated. Using 90% power Bandwidth (BW) measurement definition showed that the RRC filtering might improve spectrum efficiency by more than 75%. Furthermore using the matching RRC filters both in the transmitter and receiver provides the improved Bit Error Rate (BER) performance. In this presentation the theory of three related concepts, namely pulse shaping, Inter Symbol Interference (ISI), and Bandwidth (BW) will be touched upon. Additionally the concept of the RRC filtering and some facts about the RRC filters will be presented

    Bread from the bioactivated grain of wheat differs in high content of dietary fibers, minerals and vitamins compared to traditional types of bread, but, despite this, it has low protein and lysine content. The aim of the study was the development of bread with the raised nutritional value from the bioactivated wheat grain by use of flour from cake of wheat germ (6.5%). It has been established that the flour from wheat germ has protein biological value (77.4%) and the amino acid score according to lysine (100.3%) above 12 and 40.5%, respectively, compared with those from bioactivated wheat. During calculation of nutritive, biological and energy value of products from the bioactivated wheat grain it is revealed that the biological value of bread from wheat germ flour slightly exceeded the biological value of the bread without its addition and amounted to 70.80%, due to a high protein content and a balanced amino acid composition. The protein content in the test sample of bakery products was 19.0% higher than the control, phosphorus - 13.0%, zinc - 50.0%. PMID:27455607

    The chemical properties of liquid fermented products (LFP) as probiotics substance for alternative uses of antibiotic were studied. The LFP of 235 were sampling from markets and farmers during 2005-2006. The total count of bacteria, fungi, lactic acid bacteria (LAB), Actinomyces and coliform bacteria were conducted. Chemical analysis of LFP showed medium nitrogen (0.01- 0.55%), maximum sugar contents (0.02 - 19.40%), high lactic acid contents (0.34 - 13.01%) and low pH (2.9-5.0). LFPs were free from fecal coliform and Escherichia coil (Ec); but in LAB (1.0 - 1.25x107 cfu/ml) and high Actinomyces (1.0 - 7.5 x 106 cfu/ml). LFPs inhibited Staphylococcus aureus (Sa), Samonella typhimurium (STM), Escherichia coil (Ec) and Ec 0157 at maximum yield by using Minimal Inhibition Concentration (MIC). But Pseudomonas aeruginosa (Pa) could medium inhibited. Therefore LFP samples are suitable as probiotics for alternative use of antibiotic for animal raising.

  18. Studies on the reproductive performance of indigenous beef cattle breeds raised on-farm in Ghana

    International Nuclear Information System (INIS)

    Studies were undertaken to investigate the reproductive performance of a mixture of N'dama and West African Shorthorn (N'dama/WASH) and Sanga cattle raised under traditional management conditions on four privately owned small-holder farms. The first study involved an analysis of reproductive records and the measurement of plasma progesterone concentration to delineate the onset of various reproductive phenomena, including age at puberty and first calving, post-partum resumption of ovarian activity and other abnormal events like abortions. The second study investigated the influence of dry-season feed supplementation on reproductive performance. In study 1 the ages at first plasma progesterone rise (puberty), first mating and first calving for N'dama/WASH cattle on three farms averaged 981, 1016 and 1296 days respectively. The calving interval, calving-to-progesterone rise and calving-to-mating averaged 412, 129 and 114 days respectively. Significant differences existed among farms with Farms 1 and 2 out-performing Farm 3. The respective mean ages at first progesterone elevation, first mating and first calving for Sanga cattle (Farm 4) were 964, 990 and 1271 days while calving-to-progesterone rise, calving-to-mating and calving intervals averaged 107, 150 and 431 days. In study 2, dry-season feed supplementation generally reduced ages at puberty and first calving as well as the interval of post-partum acyclicity. (author). 18 refs, 3 figs, 9 tabs

    The Raising Sexually Healthy Children (RSHC) program is a peer-to-peer leadership training program for immigrant parents in Toronto, Canada. It was established in 1998 with the goal of promoting family sex education and parent-child communication. This evaluative study examined the developmental processes and outcomes of the RSHC program to identify the strengths, challenges and insights that can be used to improve the program. It employed a multi-case study approach to compare the RSHC programs delivered in the Chinese, Portuguese and Tamil communities. Data collection methods included focus groups, individual interviews and document analysis. The cross-case analysis identified both common and unique capacity building processes and outcomes in the three communities. In this paper, we report factors that have enhanced and hindered sustainable capacity building at the individual, group/organizational and community levels, and the strategies used by these communities to address challenges common to immigrant families. We will discuss the ecological and synergetic, but time-consuming processes of capacity building, which contributed to the sustainability of RSHC as an empowering health promotion program for immigrant communities. We conclude the paper by noting the implications of using a capacity building approach to promote family health in ethno-racial-linguistic minority communities.

    With free movement for citizens within the European Union and with distant parts of our globe becoming more accessible, cultural awareness and cultural competence are becoming important skills for nurses. Internationalisation and raising awareness of other cultural contexts are essential elements in Swedish higher education, thus explaining the variety of student exchange programmes that are available. The aim of this study was to explore Swedish nursing students' perceptions of student exchange and their experiences. Data were collected through group interviews and then analysed following the principles of content analysis. Our analysis resulted in three categories: Preparing to go abroad, Reasons for going abroad and From expectation to experience. Cultural aspects and cultural awareness were emphasised as strong motivational factors, both personal and professional, behind participation in student exchange programmes. Information was also highlighted as a crucial means of reaching potential students as well as the power of knowledge through personal experience. This study highlights the importance of student exchange in expanding the individual student's personal and professional horizons. It also stresses the importance of including a transcultural nursing element in nursing curricula.

    One hundred nineteen pen-raised wild turkeys (Meleagris gallopavo) from 12 locations in nine states in the United States were examined for coccidia by sugar flotation of intestinal contents and mucosa or by subinoculating the contents into uninfected domestic turkeys. Seventy-eight (66%) of the turkeys were positive for coccidia. There were no differences in the frequency of coccidia among adult, sub-adult or juvenile turkeys. More females (75%) were infected than males (48%). The species of coccidia from 30 of the turkeys were identified based on microscopic examination of oocysts, fresh scrapings, stained sections and inoculations of bobwhites (Colinus virginianus). The frequency of each species was Eimeria meleagrimitis (97%), E. gallopavonis (47%), E. meleagridis (27%), E. dispersa (17%), E. innocua-E. subrotunda (13%), E. adenoeides (7%) and an undescribed species (3%). Of the 30 turkeys in which the species of coccidia was determined, 30% had a single species infection, 40% had two species, 20% had three species and 10% had four species.

  3. Does Raising the Early Retirement Age Increase Employment of Older Workers?

    2013-12-01

    Two pension reforms in Austria increased the early retirement age (ERA) from 60 to 62 for men and from 55 to 58.25 for women. We find that raising the ERA increased employment by 9.75 percentage points among affected men and by 11 percentage points among affected women. The reforms had large spillover effects on the unemployment insurance program but negligible effects on disability insurance claims. Specifically, unemployment increased by 12.5 percentage points among men and by 11.8 percentage points among women. The employment response was largest among high-wage and healthy workers, while low-wage and less healthy workers either continued to retire early via disability benefits or bridged the gap to the ERA via unemployment benefits. Taking spillover effects and additional tax revenues into account, we find that for a typical birth-year cohort a one year increase in the ERA resulted in a reduction of net government expenditures of 107 million euros for men and of 122 million euros for women.

  4. Rope NDT as means to raise safety of crane and elevator use

    International Nuclear Information System (INIS)

    Steel rope NDT by magnetic flaw detectors is usual for mine hoist inspection through the world. But it is no ordinary by crane and especially by elevator inspection. However, magnetic NDT statistic data of 60 crane and 227 elevator ropes in use shows that about 23% of crane and 9% of elevator ropes should be discarded in accordance with actual discarding criterion in Russia. Russian State Rules for crane safe exploitation require the magnetic NDT while periodically inspection. But not all the inspecting companies meet it in Russia, contenting themselves by visual inspection only. This is not objective and does not provide rope inner faults detection. That is a reason of rope break rather high percentage in general statistics of crane accidents and damages. Investigation of accidents with crane ropes in Moscow region in 2001 shows that they would de prevented by the magnetic NDT fulfilled timely. The elevator rope NDT problem is not so sharp but attention should de attracted to it to raise safety of elevators. (author)

  5. Challenges of raising road maintenance funds in developing countries: An analysis of road tolling in Zimbabwe

    Directory of Open Access Journals (Sweden)

    T. C. Mbara

    2010-11-01

    Full Text Available The condition of Zimbabwe's roads has been declining due to insufficient maintenance and rehabilitation. Year on year, budget allocations have compared unfavourably with funding considered adequate to maintain highway networks and conduct modest construction work. Road infrastructure shortcomings have manifested themselves in the form of high vehicle operating costs and rampant potholes, leading to a decline in road safety and a deterioration of service levels for those who use roads to deliver goods or connect to international markets. In order to try and stop this vicious cycle of decline, the Government of Zimbabwe, on 8 August 2009, introduced a new policy of road-user charges, which involved the setting-up of 22 toll gates on the trunk road network. The overall objective was to raise revenue in order to close the funding gap, blamed for declining road quality. Although alternative methods of financing road maintenance have been debated for years, a generally accepted understanding is that road users should pay costs for road provisioning. This paper assesses the implementation of a road tolling system in Zimbabwe and describes matters relating to, inter alia, implementation strategy, initial performance outcomes and sustainability.

The objective of the present study was to parameterize and assess models of organic nitrogen mineralization in soil treated with swine raising wastewater (SRW at different temperatures and water contents. Samples of 57.3 cm3 of dystrophic Red-Yellow Latosol were mixed with SRW at the application dose of 400 kg ha-1 nitrogen, placed in plastic cups and incubated at four different temperatures (15, 20, 25 and 35°C and water contents corresponding to tensions of 10, 30, 200 and 1500 kPa. Samples were removed from the incubated soil after 3, 6, 12, 24, 48 and 96 days to quantify the ammonium and nitrate concentrations. The parameters of the soil organic nitrogen mineralization models were determined from the organic nitrogen mineralization values obtained over the different incubation periods. The value of the potentially mineralizable nitrogen (N0 in soil with application of SRW was superior that of the soil without application of SRW. The mineralization constant (k in soil with application of SRW was always superior that of the soil without application of SRW. There was a tendency for the simple exponential model to underestimate the values of the mineralized nitrogen concentration. In most of the situations the potential model was more efficient than the simple exponential model to predict the mineralization of the organic nitrogen.

    Ascaridia galli is one of the most common nematode affecting chickens. This study characterized A. galli parasites collected from South African village chickens of Limpopo (n=18) and KwaZulu-Natal (n=22) provinces using the 510bp sequences of cytochrome C oxidase subunit 1 gene of the mitochondrial DNA. Fourteen and 12 polymorphic sites were observed for Limpopo and KwaZulu-Natal sequences, respectively. Six haplotypes were observed in total. Haplotype diversity was high and ranged from 0.749 for Limpopo province to 0.758 for KwaZulu-Natal province isolates. There was no genetic differentiation between A. galli from Limpopo and KwaZulu-Natal provinces. The six South African haplotypes were unique compared to those published in the GeneBank sampled from Hy-line chickens raised under organic farming in Denmark. The utility of cytochrome C oxidase subunit 1 gene as a potential genetic marker for studying A. galli in village chicken populations is presented.

    Full Text Available The urgency of counteraction to counterfeit goods trafficking is shown. Annual loss due to counterfeit goods producing and trafficking reaches several billion dollars. There remains a danger of buying low-quality and counterfeit goods despite implementing new producing techniques and protective elements. Measures, taken by law enforcement agencies, state authorities and public human rights organizations have not led to systematic suppression of producing and trafficking of such goods. Creation of new information and reference resource, containing information blocks of protective symbols on goods and packages and illustrated materials comprising patterns of discovered counterfeit goods, can assist to increase public awareness and to give necessary information to law enforcement agencies. Organizations, realizing state and social protection of consumers and entrepreneurs, along with producers, rightholders’ representatives and law enforcement bodies can accept the responsibility of creating and functioning this information and reference system in the Internet. Such level of cooperation of all interested organizations will allow to raise efficiency of measures for counteraction to trafficking goods with violated consumer properties. The author proves the necessity to organize functioning of information and reference resource for a wide range of users. Operation of such resource should comply with main principles of generating any information resource, notably full scale, authenticity and relevance of information. The author proposes the algorithm of creating such system which provides cooperation of law enforcement agencies, producers and consumers for the purpose of preventing counterfeit goods trafficking and investigating committed crimes.

    User Experience Theory (UXT) provides us with criteria for designing products and technical systems for everyday activities (playing, learning, working,…) so as to satisfy users. Living Labs (LL), are plateforms used for the design and evaluation of technical systems. As such, they constitute tools that bring to this process some constraints., However these constraints have to be articulated to the UXT. In other words, UXT should specify the place, the role and function LL should play in the design of new products, how it should contribute to satisfying UX, and how the methods and techniques should be conceived or borrowed from other disciplines. UXT also raises ethical issues: impartiality (independent, public, replicable) of research models in the context of economical constraints (dependant, private, secret prototypes) and of industrial pressure, the use of intrusive and persuasive techniques, even with the prior informed consent of participants, ergo-marketing, deontology codes, the use of specific participants, belonging of an UX innovative solution, confidentiality with ICT, and so on. Because the UX, as well as LL literature, have shown little concerns for ethical considerations, till now, we define LL-UX ethical issues as a new research topic, and we list a number of problems to be solved in order to have an ethical LL-UX methodology for open innovation.

    Full Text Available Advances in spoken corpora analysis have brought about new insights into language pedagogy and have led to an awareness of the characteristics of spoken language. Current findings have shown that grammar of spoken language is different from written language. However, most listening and speaking materials are concocted based on written grammar and lack core spoken language features. The aim of the present study was to explore the question whether awareness of spoken grammar features could affect learners’ comprehension of real-life conversations. To this end, 45 university students in two intact classes participated in a listening course employing corpus-based materials. The instruction of the spoken grammar features to the experimental group was done overtly through awareness raising tasks, whereas the control group, though exposed to the same materials, was not provided with such tasks for learning the features. The results of the independent samples t tests revealed that the learners in the experimental group comprehended everyday conversations much better than those in the control group. Additionally, the highly positive views of spoken grammar held by the learners, which was elicited by means of a retrospective questionnaire, were generally comparable to those reported in the literature.

    Full Text Available This study focuses on the alternations of mid vowels /e/ and /o/ in the pretonic context, respectively, present in the XIX century manuscripts belonging to Castro - Paraná. As this kind of oscillation, called raising, is not a recent process in the Portuguese language, we seek for evidences of Labov uniformitarianism when describing the cases found in XIX century formal documents in comparison to the data of orality, made available by Bisol (1981 Viegas (1987, 2001 Bortoni et. al (1992, Kailer (2008. For this, we use the precepts of Historical Linguistics, joined to the Varionist theory, since we associate the qualitative approach to quantitative one, based on the structural perspective to the historical-social. The results indicated the vowel harmonization process as the main context for the application of the rule, followed by initial nasal context according to the data of orality. The precedent labiodental consonant and the next bilabial following the pretonic were more productive for /e/ and the precedent alveolar for /o/. Not all words fit into the structural rules, then, the individual investigation directed us to the realization that both neogrammarian position as the diffusionist one have importance in the investigation of variation and language change.

    Full Text Available This article describes the development and dissemination of an ecological footprint tool that provides a concise and scientifically grounded summary of the environmental impact of personal food choices. Developed to be easy to use and available to consumers via online social networking platforms, the tool aims to raise awareness and to provide an impetus for behavior change. The foodprint tool communicates scientifically informed and customized practical advice on how individuals can reduce their ecological footprint (EF (or “foodprint”. The first part of the article describes the process of developing this tool, the choice of indicator, the goals, and the results. Among other aspects, the tool enables users to understand that the largest contributors to their foodprint are sources of animal protein: dairy, meat, and fish. The second part of the article describes the strategy guiding the tool’s design and implementation, which is based on a combination of contextual communication, feedback from peers, and intrinsic motivation. In this footprint tool, a focus on food patterns, interactive feedback, and social media plays a key role. The tool consists of a survey with fifteen questions about personal food choice that allow users to receive individualized feedback, including five suggestions for reducing personal foodprints. Users can also share their results through customary social media. Due to an effective outreach campaign, a total of 90,000 Dutch consumers used this tool over a period of four months, with 1% indicating that they intended to change behavior.

  13. Me, Myself and My Brain Implant: Deep Brain Stimulation Raises Questions of Personal Authenticity and Alienation.

    2013-01-01

    In this article, I explore select case studies of Parkinson patients treated with deep brain stimulation (DBS) in light of the notions of alienation and authenticity. While the literature on DBS has so far neglected the issues of authenticity and alienation, I argue that interpreting these cases in terms of these concepts raises new issues for not only the philosophical discussion of neuro-ethics of DBS, but also for the psychological and medical approach to patients under DBS. In particular, I suggest that the experience of alienation and authenticity varies from patient to patient with DBS. For some, alienation can be brought about by neurointerventions because patients no longer feel like themselves. But, on the other hand, it seems alienation can also be cured by DBS as other patients experience their state of mind as authentic under treatment and retrospectively regard their former lives without stimulation as alienated. I argue that we must do further research on the relevance of authenticity and alienation to patients treated with DBS in order to gain a deeper philosophical understanding, and to develop the best evaluative criterion for the behavior of DBS patients.

  14. Dams and Displacement: Raising the Standards and Broadening the Research Agenda

    2010-06-01

    Full Text Available The World Commission on Dams provided an analytical overview of the cumulative effects of years of dam development. A lack of commitment or capacity to cope with displacement or to consider the civil rights of, or risks to, displaced people led to the impoverishment and suffering of tens of millions and growing opposition to dams by affected communities worldwide. However, after the WCD, little has changed for the better in terms of resettlement policies. In fact, the standards of key agencies, like the Asian Development Bank, have been lowered and diluted compared to prior policies. Dam-induced development and displacement are stifled by a 'managerialist' approach to planning, in which solutions are sought internally and subordinated to the economics that underpins the existence of the project. The aim of successful resettlement is to prevent impoverishment and to enable displaced people to share in the project’s benefits. Within the field of dam-induced resettlement, this is a lofty goal rarely achieved. However, in other fields of resettlement, such as refugee studies and adaptation to environmental change, such a goal is regarded as a minimum standard. In this paper we seek to broaden the research agenda on dam-induced resettlement and to raise the standards of development projects that entail resettlement. We do this by importing some of the considerations and concerns from practice and research from the fields of refugee studies and adaptation to environmental change.

  15. Raising New Zealand’s Terrorism Threat Level: Is Transparency Important in National Security?

    Full Text Available In mid-October 2014, ten years after the New Zealand Government confirmed the establishment of a Combined Threat Assessment Group (CTAG to advise it on a range of potential threats, the prime minister announced, for the first time, the raising of New Zealand’s domestic terrorism threat level. Unfortunately, the assessment that gave rise to the threat level’s change (or a version of it was not made public. Therefore, how were New Zealanders or others expected to properly understand the environment giving rise to the threat changes, and to judge whether the assessors got the setting right. This paper argues increased public transparency is appropriate when additional security measures resulting from a change in threat perception impact citizens’ lives and cost tax-payers more money. In presenting this argument, the paper briefly describes the role of threat assessments and how threat levels are set. In the absence of a public version of New Zealand’s threat assessment giving a cohesive, concise and transparent outline of the threat environment, the paper presents publicly available information from well-informed high office holders to see if that provides alternative and suitable transparency. Finally, the paper compares New Zealand’s terrorism threat assessment transparency processes with those of four countries with similar characteristics to New Zealand to see if alternative models of public transparency are available for consideration.

    2016-01-01

    There have been exponential gains in immuno-oncology in recent times through the development of immune checkpoint inhibitors. Already approved by the U.S. Food and Drug Administration for advanced melanoma and non-small cell lung cancer, immune checkpoint inhibitors also appear to have significant antitumor activity in multiple other tumor types. An exciting component of immunotherapy is the durability of antitumor responses observed, with some patients achieving disease control for many years. Nevertheless, not all patients benefit, and efforts should thus now focus on improving the efficacy of immunotherapy through the use of combination approaches and predictive biomarkers of response and resistance. There are multiple potential rational combinations using an immunotherapy backbone, including existing treatments such as radiotherapy, chemotherapy or molecularly targeted agents, as well as other immunotherapeutics. The aim of such antitumor strategies will be to raise the tail on the survival curve by increasing the number of long term survivors, while managing any additive or synergistic toxicities that may arise with immunotherapy combinations. Rational trial designs based on a clear understanding of tumor biology and drug pharmacology remain paramount. This article reviews the biology underpinning immuno-oncology, discusses existing and novel immunotherapeutic combinations currently in development, the challenges of predictive biomarkers of response and resistance and the impact of immuno-oncology on early phase clinical trial design.

    Full Text Available This study investigated the potential impact of e-learning on raising overseas students' cultural awareness and explored the possibility of creating an interactive learning environment for them to improve their English academic writing. The study was based on a comparison of Chinese and English rhetoric in academic writing, including a comparison of Chinese students' writings in Chinese with native English speakers' writings in English and Chinese students' writings in English with the help of an e-course and Chinese students' writings in English without the help of an e-course. Five features of contrastive rhetoric were used as criteria for the comparison. The experimental results show that the group using the e-course was successful in learning about defined aspects of English rhetoric in academic writing, reaching a level of performance that equalled that of native English speakers. Data analysis also revealed that e-learning resources helped students to compare rhetorical styles across cultures and that the interactive learning environment was effective in improving overseas students' English academic writing.

    Globodera spp. are under strict quarantine in many countries. Suppressiveness to cyst nematodes can evolve under monoculture of susceptible hosts. Females developing in potato monoculture soil infested with G. pallida populations Chavornay or Delmsen were examined for inherent microbial communities. In the greenhouse, nonheated and heat-treated (134°C for 10 min) portions of this soil were placed in root observation chambers, planted with Solanum tuberosum 'Selma', and inoculated with G. pallida Pa3 Chavornay. At harvest in Delmsen soil, cysts had fewer eggs in nonheated than heat-treated soil. In denaturing gradient gel electrophoresis analysis, bacterial and fungal fingerprints were characterized by a high variability between replicates; nonheated soils displayed more dominant bands than heated soils, indicating more bacterial and fungal populations. In amplicon pyrosequencing, females from nonheated portions frequently contained internal transcribed spacer sequences of the fungus Malassezia. Specific for the Chavornay and Delmsen population, ribosomal sequences of the bacteria Burkolderia and Ralstonia were abundant on eggs. In this first report of microbial communities in G. pallida raised in potato monoculture, candidate microorganisms perhaps associated with the health status of the eggs of G. pallida were identified. If pathologies on cyst nematodes can be ascertained, these organisms could improve the sustainability of production systems. PMID:26863445

    We show that by marrying the elementary-Goldstone-Higgs scenario and supersymmetry it is possible to raise the scale of supersymmetry breaking to several TeVs while keeping the relevant features of a natural supersymmetric extension of the Standard Model. This is achieved by first enhancing the global symmetries of the super-Higgs sector to SU(4) and then embedding the electroweak sector and the Standard-Model fermions. We determine the conditions under which the model achieves a vacuum such that the resulting Higgs is a pseudo-Goldstone boson. The main results are: the supersymmetry-breaking scale is identified with the spontaneous-symmetry-breaking scale of SU(4) which is several TeVs above the radiatively induced electroweak scale; intriguingly the global symmetry of the Higgs sector predicts the existence of two super-Higgs multiplets with one mass eigenstate playing the role of the pseudo-Goldstone Higgs; the symmetry-breaking dynamics fixes $\\tan\\beta = 1$ and requires a supplementary singlet chiral sup...

  1. Analysis of the stress raising action of flaws in laser clad deposits

    International Nuclear Information System (INIS)

    Highlights: ► Laser clad defects are 0D-pores/inclusions, 1D-clad waviness or 2D-planar defects. ► Surface pore of laser clad bar initiates fatigue cracks. ► Side edge surface pores are more critical than in-clad surface pores. ► Smaller notch radius and angle of as-laser clad surface raises stress significantly. ► Planar inner defects grow faster towards surface. - Abstract: Fatigue cracking of laser clad cylindrical and square section bars depends upon a variety of factors. This paper presents Finite Element Analysis (FEA) of the different macro stress fields generated as well as stress raisers created by laser cladding defects for four different fatigue load conditions. As important as the defect types are their locations and orientations, categorized into zero-, one- and two-dimensional defects. Pores and inclusions become critical close to surfaces. The performance of as-clad surfaces can be governed by the sharpness of surface notches and planar defects like hot cracks or lack-of-fusion (LOF) are most critical if oriented vertically, transverse to the bar axis. The combination of the macro stress field with the defect type and its position and orientation determines whether it is the most critical stress raiser. Based on calculated cases, quantitative and qualitative charts were developed as guidelines to visualize the trends of different combinations

    Although cattle movement and commingling play an important role in the inter-herd transmission of pathogens, little is known about the effect of commingling of heifers at raising operations. The objective of this study was to compare the resistance of E. coli and prevalence of Salmonella from pooled faecal pats of heifers raised off-farm at multi-source raisers (MULTI) that raised heifers from at least two farms compared with on-farm raisers (HOME), with heifers from only that farm. MULTI faecal pat samples were collected from pens with animals that had arrived at the farm within the previous 2 months (AP) and from animals that would be departing the heifer raiser in 2-3 months (DP). Corresponding age sampling was conducted at HOME raisers. Odds of ampicillin resistance were 3·0 times greater in E. coli collected from MULTI compared to HOME raisers. E. coli from AP pens had significantly (P Salmonella recovery was not significantly different between heifer-raising systems (P = 0·3). Heifer-raising system did not have a major overall impact on selection of resistant E. coli, which was strongly affected by the age of the animals sampled.

  5. Courses for "Soil Practitioner" and other measures for raising soil awareness

    Hartl, Wilfried

    2014-05-01

    Today, unfortunately, little use is made of the findings of rhizosphere research in practice. Therefore the author, together with the organic farmers` associations Distelverein and Bio Austria, developed the education programme "Soil Practitioner" for organic farmers. The 9-days` course focuses on the topics nutrient dynamics in soil, plant-root interactions, soil management, humus management and practical evaluation of soil functions. A second series of courses developed by Bio Forschung Austria aims at improving organic matter management on farm level. In order to enable the farmers to estimate if the humus content of their fields is increasing or decreasing, they are familiarized with the humus balancing method. In a second step, humus balances of farmers' fields are calculated and the results are discussed together. Another activity to raise soil awareness is the "Mobile Soil Laboratory", which is presented at various events. The soil functions are demonstrated to the public using special exhibits, which illustrate for example infiltration rate in soils with and without earthworms, or water holding capacity of soils with and without earthworms or erosion intensity on soil blocks from adjacent plots which had been cultivated with different crop rotations. The habitat function of soil is illustrated with portable rhizotrons, which show the ability of plants to root surprisingly deep and to penetrate compacted soil layers. Another exhibit shows a habitat preference test between differently fertilized soils with earthworms as indicator organisms. In the "Mobile Soil Laboratory", visitors are also invited to watch live soil animals through the binocular microscope. They are supplied with information on the soil animals` habitat and behaviour and on how agriculture benefits from biologically active soil. And last but not least, the "Root Demonstration Arena" at our institute features a 3-m-deep excavation lined with large viewing windows into the soil profile, where

  6. Raising voices: How sixth graders construct authority and knowledge in argumentative essays

    Science.gov (United States)

    Monahan, Mary Elizabeth

    This qualitative classroom-based study documents one teacher-researcher's response to the "voice" debate in composition studies and to the opposing views expressed by Elbow and Bartholomae. The author uses Bakhtin's principle of dialogism, Hymes's theory of communicative competence, as well as Ivanic's discussion of discoursally constructed identities to reconceptualize voice and to redesign writing instruction in her sixth grade classroom. This study shows how students, by redefining and then acting on that voice pedagogy in terms that made sense to them, shaped the author's understanding of what counts as "voiced" writing in non-narrative discourse. Based on a grounded-theory analysis of the twenty-six sixth graders' argumentative essays in science, the author explains voice, not as a property of writers or of texts, but as a process of "knowing together"---a collaborative, but not entirely congenial, exercise of establishing one's authority by talking with, against, and through other voices on the issue. As the results of this study show, the students' "I-Ness" or authorial presence within their texts, was born in a nexus of relationships with "rivals," "allies" and "readers." Given their teacher's injunctions to project confidence and authority in argumentative writing, the students assumed fairly adversarial stances toward these conversational partners throughout their essays. Exaggerating the terms for voiced writing built into the curriculum, the sixth graders produced essays that read more like caricatures than examples of argumentation. Their displays of rhetorical bravado and intellectual aggressiveness, however offsetting to the reader, still enabled these sixth graders to composed voiced essays. This study raises doubts about the value of urging students to sound like their "true selves" or to adopt the formal registers of academe. Students, it seems clear, stand to gain by experimenting with a range of textual identities. The author suggests that voice

  7. Gonadal differentiation in frogs, Rana japonica and R. brevipoda, raised from UV irradiated eggs

    International Nuclear Information System (INIS)

    The gonadal differentiation of anurans, Rana japonica and R. brevipoda, was examined in animals raised from eggs which had been irradiated at the vegetal hemisphere with UV (9300 erg/mm2) at the 2-cell stage. In R. japonica about 70% of the larvae at stage I from the pressed and UV-irradiated eggs were germ cell free, but at a stage immediately after metamorphosis all animals had at least some germ cells, although their gonads often were extremely small and poorly differentiated. When male animals matured sexually, many of them had abnormal gonads. However, all of them were shown by artificial means to be capable of fertilization. In the nonpressed and irradiated group, no larvae were germ cell free and the animals immediately after metamorphosis showed nearly normal gonadal differentiation except for the presence of a few degenerate oocytes in the ovaries. The results in R. brevipoda were basically similar to those in R. japonica. In both species, sex ratios were determined at two stages, the first immediately after metamorphosis and the other when the animals matured, as based on gonad morphology and histology and on external sexually dimorphic characters as well. Sex ratios at these two stages in frogs from the pressed and irradiated eggs differed markedly in R. brevipoda. The ratio was normal at metamorphosis but high M/F ratios occurred when animals became mature. That sex reversal took place in this species as well as in R. japonica (in which sex-ratio deviation was not statistically significant) was supported by the sex ratios of the progenies of these supernumerary males

  8. Raising the temperature of the UK heat pump market: Learning lessons from Finland

    International Nuclear Information System (INIS)

    Heat pumps play a central role in decarbonising the UK's buildings sector as part of the Committee on Climate Change's (CCC) updated abatement scenario for meeting the UK's fourth carbon budget. However, the UK has one of the least developed heat pump markets in Europe and renewable heat output from heat pumps will need to increase by a factor of 50 over the next 15 years to be in line with the scenario. Therefore, this paper explores what lessons the UK might learn from Finland to achieve this aim considering that its current level of heat pump penetration is comparable with that outlined in the CCC scenario for 2030. Despite the two countries’ characteristic differences we argue they share sufficient similarities for the UK to usefully draw some policy-based lessons from Finland including: stimulating new-build construction and renovation of existing stock; incorporating renewable heat solutions in building energy performance standards; and bringing the cost of heat pumps in-line with gas fired heating via a combination of subsidies, taxes and energy RD&D. Finally, preliminary efforts to grow the heat pump market could usefully focus on properties unconnected to the gas-grid, considering these are typically heated by relatively expensive oil or electric heating technologies. -- Highlights: •Heat pumps are expected to play a key role in meeting the UK's 4th carbon budget. •Today, heat pump deployment per capita in the UK is one of the lowest in Europe. •Finland offers some policy lessons given its high level of heat pump deployment. •Policies: raising build rates, building standards and heat pump cost-effectiveness. •Deployment efforts should focus on buildings not heated by relatively low-cost gas

    Full Text Available Objective: This article provides a non-technical introduction to analyses of fertility which are based on a rational-choice paradigm and which acknowledge that raising children may have a strong impact on the well-being of parents that can be described in terms of costs and benefits. It surveys different types of economic fertility models which can be used to address a variety of research questions, and it also discusses some basic strengths and weaknesses of applying economic analyses in this particular field. Results: Starting from a seminal contribution by Becker (1960 which may have been of little use for applied research or for interdisciplinary work, the economic theory of fertility has unfolded a differentiated research programme with indispensable contributions to the broader field of fertility research. Important features are the inclusion of (i different bargaining positions and differing incentives of partners interacting in fertility choices; (ii simultaneous decisions regarding labour force participation (as well as education and fertility, and the role played by employers, labour market institutions, and other public interventions; (iii the idea that children (or their "human capital" are investment goods with various kinds of returns that may be dispersed over an extremely long period of time, are subject to enormous uncertainties, and are strongly influenced by the social context and, again, by public policies. Conclusions: Economic aspects and elements of economic models should be included in any large-scale attempt at understanding fertility behaviour through interdisciplinary research. Improvements in the data infrastructure, which are only partly underway thus far, would be an important pre-requisite.

    It is likely that the Phanerozoic biosphere has been exposed to recurrent episodes of elevated UV-B radiation caused by ozone depletion events. Natural phenomena that have the potential to disrupt the stratospheric ozone balance include asteroid or comet impacts and large-scale volcanism. However, while UV-B exposure has long been known to be damaging to life, no distinctive UV-B effects have so far been detected in the fossil record of terrestrial and aquatic organisms. Notably land plants display a wide variety of biochemical and morphological responses to enhanced UV-B exposure. Adverse effects of UV-B stress on photosynthesis, growth and development of plants are largely due to altered gene action. Progressive increase in mutation rates indicates that UV-B enhancement can generate genomic instability of plant populations. Among fossil remains of land plants, only successive assemblages of dispersed spores and pollen may provide the sample size and stratigraphic spacing needed to recognize morphological traits that could indicate enhanced mutation. In spores and pollen of recent plants, mutational effects can be reflected morphologically by abnormal variation in overall shape and size, disorganized wall structure and/or the presence of permanent tetrads in which individual microspores have failed to separate from one another during sporogenesis. On the basis of spore/pollen records from Europe, North America, Asia and Africa, we document the worldwide proliferation of dispersed tetrads of microspores of heterosporous lycopsids that occurred in conjunction with the dramatic end-Permian biosphere crisis. This conspicuous `tetrad event' may reflect an episode of raised UV-B stress, resulting from ozone depletion induced by outgassing of volatile halocarbons at the time of emplacement of voluminous doleritic intrusives in organic-rich Paleozoic deposits in Siberia.

    Full Text Available Gender identity and gender role are expected to be consistent with gender assignment for optimal DSD management outcome. To our knowledge, our study is the first to attempt evaluation of gender related outcomes in Turkish DSD patients.After receiving institutional ethical board approval and subject (or parent informed consent, subjects with DSD raised as girls (22 patients 46 XX DSD,11 patients 46XY DSD answered 566 questions of the Minnesota Multiphasic Personality Inventory (MMPI questionnaire including 60- item Masculinity-Femininity (MF subscale which was the focus in this study. Controls (n:50 were females similar to the probands in age, level of education, relationship status and having a job or not also answered all questions. The answers were evaluated by a trained psychologist(D.I. on MMPI .For statistical purposes, 7 findings were obtained from the data related to the MF subscale from the patients and controls. Of these 7 findings (S1-S7, two were associated with masculinity (S3-S4 and another two were associated with femininity (S5-S6In DSD patients, the percentages of masculinity findings were significantly higher when compared to controls (p< 0.001 and p< 0.001 for S3 and S4 respectively. In controls, the percentages of femininity findings were significantly higher when compared to DSD females (p< 0.001 and p< 0.001 for S5 and S6 respectively.There was no significant difference between 46XX DSD patients and 46XY DSD patients with respect to the percentage of any of the 7 findings. Two patients requested gender change to male;only these two patients had the finding stating that sexual impulses could come to existence as actions(S7.In conclusion efforts to identify modifiable factors with negative impact and thus modifying them, and professional guidance may be important in minimizing the encountered gender related problems in DSD patients

    The Utah Geological Survey's (UGS) Geologic Hazards Program has partnered with the U.S. Army Corps of Engineers to create geologically derived web-based flood hazard maps. Flooding in Utah communities has historically been one of the most damaging geologic hazards. The most serious floods in Utah have generally occurred in the Great Salt Lake basin, particularly in the Weber River drainage on the western slopes of the Wasatch Range, in areas of high population density. With a growing population of 2.9 million, the state of Utah is motivated to raise awareness about the potential for flooding. The process of increasing community resiliency to flooding begins with identification and characterization of flood hazards. Many small communities in areas experiencing rapid growth have not been mapped completely by the Federal Emergency Management Agency (FEMA) Flood Insurance Rate Maps (FIRM). Existing FIRM maps typically only consider drainage areas that are greater than one square mile in determining flood zones and do not incorporate geologic data, such as the presence of young, geologically active alluvial fans that indicate a high potential for debris flows and sheet flooding. Our new flood hazard mapping combines and expands on FEMA data by incorporating mapping derived from 1:24,000-scale UGS geologic maps, LiDAR data, digital elevation models, and historical aerial photography. Our flood hazard maps are intended to supplement the FIRM maps to provide local governments and the public with additional flood hazard information so they may make informed decisions, ultimately reducing the risk to life and property from flooding hazards. Flooding information must be widely available and easily accessed. One of the most effective ways to inform the public is through web-based maps. Web-based flood hazard maps will not only supply the public with the flood information they need, but also provides a platform to add additional geologic hazards to an easily accessible format.

    Full Text Available Each four young bulls of Madura cattle and Ongole Crossbred (OC cattle were used to study theefficiency of ruminal fermentation by comparing the proportion of Volatile Fatty Acid (VFA of thesetwo breeds which were raised under intensive feeding. All the cattle were in about 1.5 years-old with anaverage body weight of 147.75 ± 14.57 kg and 167 ± 22.57 kg, for Madura and OC cattle, respectively.They were fed Napier grass (Pennisetum purpureum hay, and concentrate feeding consists of pollard,soybean meal and rice bran for 10 weeks. Parameters measured were concentration of VFA at 0, 3 and 6h post-feeding and pH. The concentration of VFA in both Madura and OC cattle was peaked at 3 h postfeeding,being 136.1 mmol and 158.9 mmol, respectively, and then were decreased at 6 h post-feeding ata level of 58.1 and 98.2 mmol, respectively. The proportion of acetic acid in Madura and OC cattle were53.33% and 52.0% of total VFA, respectively, while the proportion of propionic acid and butyric acidwere 28.80% and 17.87% for Madura cattle, and 30.71% and 17.28% for OC cattle, respectively. Inaddition, the Acetic/Propionic ratios were 1.85 and 1.69 for Madura and OC cattle, respectively. RumenpH conditions of both cattle breeds tended to be basic, i.e. Madura cattle was ranged at 8.0-8.4, while thePO cattle was ranged at 7.6-8.4. In conclusion, both cattle breeds (Madura and OC cattle have a similarefficiency to utilize the feeds in the rumen.

    Transmission of Oesophagostomum dentatum and Trichuris suis was studied in outdoor reared pigs. Six farrowing paddocks were naturally contaminated in May to mid-June 2001 by experimentally infected seeder pigs. In early July 1 sow farrowed on each paddock and starting at week 3 post-partum (p.p.) the offspring was slaughtered serially every 2 weeks for parasite recovery. Faeces were collected regularly for parasite egg counts and acid-insoluble ash (AIA) content as an indicator of geophagy. Weaning took place at week 7 p.p. by removing the sow. Paddock infection levels were estimated in mid-June (O. dentatum) and late November (O. dentatum and T. suis) using helminth-naïve tracer pigs. Soil and vegetation samples were collected regularly. Despite a high initial contamination by the seeder pigs, O. dentatum paddock infectivity was negligible to low throughout the raising of the experimental piglets, which had a slow accumulation of nodular worms ending with a mean of 422 worms/pig at week 19 p.p. As only few eggs developed to infectivity overall T. suis transmission was minimal. The first T. suis were recovered at week 11 p.p. and the highest mean burden of 21 worms/pig was recorded at week 19 p.p. The experimental pigs initially had a high faecal level of AIA although it decreased over time. The results are discussed in relation to the biological characteristics of the 2 parasites and their occurrence in organic pig production. PMID:16740181

    The aim of the present study was to characterize ovarian follicular development and steroid concentrations during postpartum and the estrous cycle of Brangus Ibagé cows (3/8 Nelore + 5/8 Aberdeen Angus) with different levels of fertility. Cows were classified as having high or low fertility according to the calving interval (CI). The average CI of the herd from which cows used in this study were selected was 404.6+/-5.44 and 711.2+/-20.89 days for the high and low fertility groups, respectively. Four cows of high fertility and five cows of low fertility had calves removed between 70 and 100 days after parturition. Ovarian activity was monitored daily by ultrasound for 16 days after calf removal. Days to emergency of the first follicular wave after calf removal, number of follicles with diameter >9 mm, growth rate of largest follicle, maximum diameter of largest follicle, length (days) and number of follicular waves were recorded. During this period, blood was collected daily for measurements of serum progesterone (P(4)) and estradiol (E(2)) concentrations. In another experiment, ovarian activity and P(4) and E(2) concentrations were examined during estrous cycle in five cows of high fertility and four cows of low fertility. Ovarian activity and steroid concentrations were assessed from the day prior to estrus to the 15th day of the estrous cycle (estrus = day 0). In postpartum cows of high fertility, the total number of follicles >5mm and the maximum diameter of the largest follicle were higher than in cows of low fertility (P 5mm, but the day effect was significant (P < 0.01). Plasma concentrations of P(4) and E(2) were similar in both groups. These data suggest that cows, from a population raised in the same environment have different fertility as a consequence of individual physiological characteristics. PMID:12220814

    2007-12-01

    "Dark Skies as a Universal Resource” is one of 7 themes targeted for the International Year of Astronomy in 2009. The theme's goal is to raise public awareness of the impact of artificial lighting on local environments and the ongoing loss of a dark night sky as a natural resource for much of the world's population. To reach this goal, activities are being developed which highlight dark skies preservation issues 1) through new technology (e.g., programs at planetaria, blogging, podcasting); 2) at events such as star parties and observatory open houses; 3) in arts, entertainment and storytelling (e.g., art competitions, documentaries, lectures, native American traditions); 4) through unaided-eye and digital-meter star count programs involving citizen-scientists; and 5) by relating them to public health, economic issues, ecological consequences, energy conservation, safety and security. A centerpiece of the Dark Skies theme is the unaided-eye and digital-meter versions of the GLOBE at Night program. The unaided-eye version directs citizen-scientists on how to observe and record the brightness of the night sky by matching its appearance toward the constellation of Orion with one of 7 stellar maps of different limiting magnitudes. For the "digital” version, low-cost meters are used by citizen-scientists to measure the integrated sky brightness. Data sets and maps of both versions are supplied on-line for further capstone activities. In the presentation, we will outline the activities being developed as well as plans for funding, implementation, marketing and the connections to the global cornerstone IYA project, "Dark Skies Awareness".

    The development of 2-phenylbenzoxazoles as inhibitors of cholesteryl ester transfer protein (CETP) is described. Initial efforts aimed at engineering replacements for the aniline substructures in the benchmark molecule. Reversing the connectivity of the central aniline lead to a new class of 2-(4-carbonylphenyl)benzoxazoles. Structure-activity studies at the C-7 and terminal pyridine ring allowed for the optimization of potency and HDLc-raising efficacy in this new class of inhibitors. These efforts lead to the discovery of benzoxazole 11v, which raised HDLc by 24 mg/dl in our transgenic mouse PD model.

  19. Seven steps to raise world security. Op-Ed, published in the Finanical Times

    International Nuclear Information System (INIS)

    In recent years, three phenomena have radically altered the security landscape. They are the emergence of a nuclear black market, the determined efforts by more countries to acquire technology to produce the fissile material usable in nuclear weapons and the clear desire of terrorists to acquire weapons of mass destruction. The IAEA has been trying to solve these new problems with existing tools. But for every step forward, we have exposed vulnerabilities in the system. The system itself - the regime that implements non-proliferation treaty needs reinforcement. Some of the necessary remedies can be taken in New York at the Meeting to be held in May, but only if governments are ready to act. With seven straightforward steps, and without amending the treaty, this conference could reach a milestone in strengthening world security. The first step: put a five-year hold on additional facilities for uranium enrichment and plutonium separation. Second, speed up existing efforts, led by the US global threat reduction initiative and others, to modify the research reactors worldwide operating with highly enriched uranium - particularly those with metal fuel that could be readily employed as bomb material. Third, raise the bar for inspection standards by establishing the 'additional protocol' as the norm for verifying compliance with the NPT. Fourth, call on the United Nations Security Council to act swiftly and decisively in the case of any country that withdraws from the NPT, in terms of the threat the withdrawal poses to international peace and security. Fifth, urge states to act on the Security Council's recent resolution 1540, to pursue and prosecute any illicit trading in nuclear material and technology. Sixth, call on the five nuclear weapon states party to the NPT to accelerate implementation of their 'unequivocal commitment' to nuclear disarmament, building on efforts such as the 2002 Moscow treaty between Russia and the US. Last, acknowledge the volatility of

  20. Normal inter-limb differences during the straight leg raise neurodynamic test: a cross sectional study

    2012-12-01

    Full Text Available Abstract Background The straight leg raise (SLR neurodynamic test is commonly used to examine the sensitivity of the lower quarter nervous system to movement. Range of motion during the SLR varies considerably, due to factors such as age, sex and activity level. Knowing intra-individual, inter-limb differences may provide a normative measure that is not influenced by such demographic characteristics. This study aimed to determine normal asymmetries between limbs in healthy, asymptomatic individuals during SLR testing and the relationship of various demographic characteristics. Methods The limb elevation angle was measured using an inclinometer during SLR neurodynamic testing that involved pre-positioning the ankle in plantar flexion (PF/SLR and neutral dorsiflexion (DF/SLR. Phase 1 of the study included 20 participants where the ankle was positioned using an ankle brace replicating research testing conditions. Phase 2 included 20 additional participants where the ankle was manually positioned to replicate clinical testing conditions. Results The group average range of motion during PF/SLR was 57.1 degrees (SD: 16.8 degrees on the left and 56.7 degrees (SD: 17.2 degrees on the right while during DF/SLR the group average was 48.5 degrees (SD: 16.1 degrees on the left and 48.9 degrees (SD: 16.4 degrees on the right. The range of motion during SLR was moderately correlated to weight (−0.40 to −0.52, body mass index (−0.41 to −0.52, sex (0.40 to 0.42 and self-reported activity level (0.50 to 0.57. Intra-individual differences between limbs for range of motion during PF/SLR averaged 5.0 degrees (SD: 3.5 degrees (95% CI: 3.8 degrees, 6.1 degrees and during DF/SLR averaged 4.1 degrees (SD: 3.2 degrees (95% CI: 3.1 degrees, 5.1 degrees but were not correlated with any demographic characteristic. There were no significant differences between Phase 1 and Phase 2. Conclusions Overall range of motion during SLR was related to sex, weight, BMI and

    A conference to raise awareness In the Netherlands, little research on earth walls has been done. To improve attention for earth walls, a number of organisations, including Geoheritage NL, organized a conference at the RCE, the Cultural Heritage Agency of the Netherlands. The conference* presented a state-of-the-art of research done. The book with the presentations, and extra case studies added, was published in December 2012. The book concludes with a research action list, including earth science research, and can be downloaded freely from the internet. It has English summaries. The earth science aspects Historical earth walls do not only add cultural value to a landscape, but also geodiversity value. Apart from geomorphological aspects, the walls contain information about past land- and climate conditions: - They cover up a former topography, a past landscape. A relevant source of scientific information where lands are levelled, as is the case in many parts of The Netherlands; - The soil formation under the earth wall is a reference soil. The soil formation in the top of the wall gives insight in the rate of soil formation in relationship with the age and parent material of the wall; - The soil profiles of different age have ecological significance. Older walls with a more pronounced soil formation often hold forest flora that has disappeared from the surrounding environment, such as historical bush or tree species, autogenetic DNA material or a specific soil fauna; - The materials in the earth walls tell about the process of wall-building. Paleosols and sedimentary structures in the earth walls, in the gullies and colluvial fans along the walls contain information about past land management and climate. - The eroded appearance of the earth walls is part of their history, and contain information about past management and land conditions, has ecological relevance, for example for insects, and is often visually more interesting. Insight in the rates of erosion are

    During the past century, drought has caused substantial social, economic, and ecological changes in North America. Semi-arid regions of the western United States have been particularly vulnerable to drought and drought impacts. However, drought has been less frequent and severe in humid regions of North America during the past century, leading to the perception that these regions are not particularly vulnerable to hydroclimatic change. Although the tree-ring record provides a detailed perspective on drought frequency and duration for the past millennium in the western US, much less is known about the long-term history of water balance in humid regions like the Northeast. To better understand the long-term history of moisture variability in this region, we developed records of past hydroclimate variability spanning the past 3000 years from three raised bogs in Maine. We used testate amoeba-inferred water table depths and measurements of the degree of peat decomposition to reconstruct the paleohydrology at each site. Proxy hydroclimate records from these bogs were combined (stacked), creating a single, regional record of hydroclimate variability. Our results reveal that droughts longer or more severe than any recorded during the 20th century have been common in the region, with particularly prominent multidecadal-to-centennial scale droughts centered on ~1800 yr BP, ~1650 yr BP, ~850 yr BP, and ~550 yr BP. Hydroclimate variability was greatest during the Medieval Climate Anomaly, a time period of relative warmth in much of the Northern Hemisphere. Droughts in Maine during the past century have been associated with northerly wind anomalies and anomalously cool sea surface temperatures in the adjacent northwestern North Atlantic, patterns that are likely associated with broader circulation features such as those associated with the North Atlantic Oscillation. Droughts of the past 3000 years may have been characterized by similar responses to the coupled ocean

    Cuttlefish are known for their ability to quickly alter their total appearance, or body pattern, to camouflage or to communicate with predators, prey and conspecifics. The body patterns of some species have been extensively documented to gain a better understanding of their behaviors. However, the flamboyant cuttlefish (Metasepia pfefferi) is largely unstudied. Recently, aquarists have been able to breed, house and display M. pfefferi, giving researchers ample opportunities to study their behavior under those conditions. This study aimed to identify the dorsally-visible components of the body patterns used by 5 sexually-mature, freely-behaving, F5 generation M. pfefferi in their home aquarium at The Seas in Epcot at Walt Disney World Resorts(®), Lake Buena Vista, FL, USA. Furthermore, we aimed to determine the most probable patterns used by this population of animals and to create a database of components that can be used in future behavioral studies. We found that this population of M. pfefferi use a combination of 7 textural, 14 postural, 7 locomotor and between 42 and 75 chromatic components in their home aquarium. Using maximum likelihood analysis and AutoClass@IJM software, we found that these components combine to generate 11 distinct body patterns. The software was able to sort 98% of the live animal observations into one of the 11 patterns with 90% confidence and 88% of observations with 99% confidence. Unusually for cuttlefish, 8 of the 11 identified patterns contained at least one "traveling" component (i.e., traveling waves or blinking spots) in which the colors on the skin appeared to travel on the animal's mantle. In other species, these components are generally seen during hunting or aggression, but this population of M. pfefferi uses them frequently during a variety of contexts in their home aquarium. With few published data on the behavior of M. pfefferi in their natural environment, we cannot compare the behavior of the tank-raised individuals in

    Full Text Available How can we address the teaching of English as a second language in South African secondary schools given what we know about the nature of language acquisition, learners' lack of exposure to mother tongue English speakers and their widely divergent language experience at primary school/eve!? This paper argues that grammatical consciousness-raising should be the basis of the secondary school syllabus. Current syllabuses do not adequately consider language acquisition processes. Although their aims are defined as 'communicative: syllabuses continue to focus on what language should be taught, with the result that they remain essentially lists of structures and functions. Syllabuses should be completely redesigned to develop a coherent process-focused, problemsolving approach to second language teaching. At the moment there is a distinct reluctance to make any definitive pronouncements about the place of language instruction in the classroom. This has a detrimental effect on both teachers and learners. The only way to cope with the developing language needs of the learner in the secondary school is through a more conscious study of how language is used in natural discourse. A more deliberate language control on the part of the learner will enhance the efficacy of extensive listening, speaking, reading and writing activities designed to supply input which is a necessary but not sufficient criterion for acquisition at this leveL Hoe kan ons die onderrig van Engels as 'n tweede taal in Suid-Afrikaanse sekondere skole aanspreek, gegee ons kennis van die aard van taalverwerwing, die leerders se gebrek aan blootstelling aan Engels-moederlaalsprekers en hul uiteenlopende taalondervinding op laerskoolvlak?

    2010-12-01

    With half of the world’s population now living in cities, many urban dwellers have never experienced the wonderment of pristinely dark skies and maybe never will. Light pollution is obscuring people’s long-standing natural heritage to view stars. The GLOBE at Night program (www.globeatnight.org) is an international citizen-science campaign to raise public awareness of the impact of light pollution by encouraging everyone everywhere to measure local levels of night sky brightness and contribute observations online to a world map. In the last 5 years, GLOBE at Night has been the most productive public light pollution monitoring campaign, collecting over 52,000 observations in a two-week period annually. This year, during the moonless two weeks in March, the campaign set a record high of over 17,800 measurements from people in 86 countries. Foundational resources are available to facilitate the public’s participation in promoting dark skies awareness. The GLOBE at Night website explains clearly the simple-to-participate-in 5 step program and offers background information and interactive games on key concepts. The program has been expanded to include trainings of the general public, but especially educators in schools, museums and science centers, in unique ways. Education kits for dark skies awareness have been distributed at the training workshops. The kit includes material for a light shielding demonstration, a digital Sky Quality Meter and “Dark Skies Rangers” activities. The activities are on how unshielded light wastes energy, how light pollution affects wildlife and how you can participate in a citizen-science star-hunt like GLOBE at Night. In addition, projects are being developed for what to do with the data once it is taken. The GLOBE at Night data from different years can be compared to look for trends over time or with population density maps. The data can also be used to search for dark sky oases or to monitor lighting ordinance compliance. Most

    Full Text Available Abstract Background Brazil holds the largest commercial cattle populations worldwide. Local cattle breeds can be classified according to their origin, as exotic or Creole. Exotic breeds imported in the last 100 years, both zebuine and taurine, currently make up the bulk of the intensively managed populations. Locally adapted Creole breeds, originated from cattle introduced by the European conquerors derive from natural selection and events of breed admixture. While historical knowledge exists on the Brazilian Creole breeds very little is known on their genetic composition. The objective of this study was to assess the levels of genetic diversity, phylogenetic relationships and patterns of taurine/zebuine admixture among ten cattle breeds raised in Brazil. Results Significant reduction of heterozygosity exists due both to within-population inbreeding and to breed differentiation in both subspecies (taurine and zebuine. For taurine breeds the number of markers that contribute to breed differentiation is larger than for zebuine. A consistently similar number of alleles was seen in both subspecies for all microsatellites. Four Creole breeds were the most genetically diverse followed by the zebuine breeds, the two specialized taurine breeds and the Creole Caracu. Pairwise genetic differentiation were all significant indicating that all breeds can be considered as genetically independent entities. A STRUCTURE based diagram indicated introgression of indicine genes in the local Creole breeds and suggested that occasional Creole introgression can be detected in some Zebuine animals. Conclusion This study reports on a comprehensive study of the genetic structure and diversity of cattle breeds in Brazil. A significant amount of genetic variation is maintained in the local cattle populations. The genetic data show that Brazilian Creole breeds constitute an important and diverse reservoir of genetic diversity for bovine breeding and conservation. The

    This study assessed milk yield and composition of Angus and Angus-cross beef cows raised in southern Brazil. A total of 128 records were collected in 2 consecutive calving seasons from cows between 3 and 5 yr of age of 4 breed compositions: Angus (ANAN), Caracu × Angus (CRAN), Hereford × Angus (HHAN), and Nelore × Angus (NEAN). These cows were mated to Brangus (BN) or Braford (BO) bulls and managed under extensive grazing conditions in southern Brazil. Milk production of these cows was assessed by 2 procedures: indirectly by the calf weigh-suckle-weigh procedure (WD) and directly by machine milking (MM). Lactation curves were estimated using nonlinear regression and the following related traits were derived: peak yield (PY), peak week (PW), total yield at 210 d (TY210), and lactation persistence (PERS). Milk composition and calf weaning weight adjusted to 210 d (WW210) were also determined. The MM technique was considered more accurate because of lower standard errors of estimated means, greater statistical power, and greater correlation between TY210 and WW210 (0.50) compared to WD (0.36). Considering the more precise evaluation by MM, the CRAN and NEAN cows had greater TY210 (1070 and 1116 kg, respectively) and PY (8.1 and 7.8 kg, respectively) compared to ANAN and HHAN cows, which had 858 and 842 kg for TY210 and 6.6 and 6.3 kg for PY, respectively. The NEAN cows had the latest PW at 10.8 wk. Late-calving cows had 21% lower TY210 compared to cows that calved earlier. Milk composition was influenced by cow genotype, with CRAN and NEAN cows producing milk with greater fat (3.8 and 3.9%, respectively) and protein (3.2 and 3.1%, respectively) content compared to ANAN and HHAN cows. Regardless of the genotype, fat, protein, and total solids increased in concentration from beginning to end of lactation, while lactose content decreased. Crossbreeding of Angus with adapted breeds of taurine or indicine origin can be effective in increasing milk yield and nutrient

    Wetland ecosystems play a significant role in the global carbon (C) cycle. Wetlands act as a major long-term storage of carbon by sequestrating carbon-dioxide (CO2) from the atmosphere. Meanwhile, they can emit significant amounts of methane (CH4) due to anaerobic microbial decomposition. The Burns Bog Ecological Conservancy Area (BBECA) is recognized as one of Canada's largest undeveloped natural areas retained within an urban area. Historically, it has been substantially reduced in size and degraded by peat mining and agriculture. Since 2005, the bog has been declared a conservancy area, and the restoration efforts in BBECA focus on rewetting the disturbed ecosystems to promote a transition back to a raised bog. A pilot study measured CH4, CO2 and N2O exchanges in 2014 and concluded to monitor CO2, CH4 fluxes continuously. From the perspective of greenhouse gas (GHG) emissions, CO2 sequestered in bog needs to be protected and additional CO2 and CH4 emissions due to land-cover change need to be reduced by wise management. In this study, we measured the growing-season (June-September) fluxes of CO2 and CH4 exchange using eddy covariance (EC). A floating platform with an EC system for both CO2 (closed-path) and CH4 (open-path) began operation in June 2015. During the growing-season, gross ecosystem photosynthesis (GEP) and ecosystem respiration (Re) averaged 5.87 g C m-2 day-1 and 2.02 g C m-2 day-1, respectively. The magnitude of GEP and Re were lower than in previous studies of pristine northern peatlands. The daily average CH4 emission was 0.99 (±1.14) g C m-2 day-1 and it was higher than in most previous studies. We also characterized how environmental factors affected the seasonal dynamics of these exchanges in this disturbed peatland. Our measurements showed that soil temperature and soil water content were major drivers of seasonal changes of GHG fluxes. The daily average GHG warming potential (GWP) of the emissions in the growing seasons (from CO2 and CH4

  11. Compromised metamorphosis and thyroid hormone changes in wood frogs (Lithobates sylvaticus) raised on reclaimed wetlands on the Athabasca oil sands

    International Nuclear Information System (INIS)

    The wet landscape approach to oil sands tailings reclamation in the Athabasca Oil Sands region involves creating wetlands from fluid tailings in mined-out pits. We measured time to metamorphosis, thyroid hormone status, and detoxification enzyme (EROD) induction in Wood frog (Lithobates sylvaticus) tadpoles raised on reclaimed oil sands wetlands of different ages [young (≤7 yr) vs. old (>7 yr)] and compared data with tadpoles raised on reference (control) wetlands. Metamorphosis was delayed or never occurred in tadpoles raised in young tailings; those exposed to older tailings developed similarly to those in reference wetlands. Thyroid hormone disruption likely played an important role in the metamorphosis delay as the T3:T4 ratio was lowest in tadpoles raised in young, tailings-affected wetlands. Our findings suggest tailings wetlands become less toxic with age, and that these amphibians will be able to complete their life cycle in tailing wetlands that have sufficiently detoxified with age. - This work provides guidance for reclamation of oil sands tailings and shows the usefulness of frogs and caging studies in environmental toxicology.

    Stephanie C Gordts

    Full Text Available BACKGROUND: Hypercholesterolemia and low high density lipoprotein (HDL cholesterol contribute to coronary heart disease but little is known about their direct effects on myocardial function. Low HDL and raised non-HDL cholesterol levels carried increased risk for heart failure development in the Framingham study, independent of any association with myocardial infarction. The objective of this study was to test the hypothesis that increased endothelial progenitor cell (EPC number and function after lipid lowering or HDL raising gene transfer in C57BL/6 low density lipoprotein receptor deficient (LDLr(-/- mice may be associated with an enhanced relative vascularity in the myocardium and an improved cardiac function. METHODOLOGY/PRINCIPAL FINDINGS: Lipid lowering and HDL raising gene transfer were performed using the E1E3E4-deleted LDLr expressing adenoviral vector AdLDLr and the human apolipoprotein A-I expressing vector AdA-I, respectively. AdLDLr transfer in C57BL/6 LDLr(-/- mice resulted in a 2.0-fold (p<0.05 increase of the circulating number of EPCs and in an improvement of EPC function as assessed by ex vivo EPC migration and EPC adhesion. Capillary density and relative vascularity in the myocardium were 28% (p<0.01 and 22% (p<0.05 higher, respectively, in AdLDLr mice compared to control mice. The peak rate of isovolumetric relaxation was increased by 12% (p<0.05 and the time constant of isovolumetric relaxation was decreased by 14% (p<0.05 after AdLDLr transfer. Similarly, HDL raising gene transfer increased EPC number and function and raised both capillary density and relative vascularity in the myocardium by 24% (p<0.05. The peak rate of isovolumetric relaxation was increased by 16% (p<0.05 in AdA-I mice compared to control mice. CONCLUSIONS/SIGNIFICANCE: Both lipid lowering and HDL raising gene transfer have beneficial effects on EPC biology, relative myocardial vascularity, and diastolic function. These findings raise concerns over the

    Purpose Mitochondria are essential for energy production in the muscle cell and for this they are dependent upon a sufficient supply of oxygen by the circulation. Exercise training has shown to be a potent stimulus for physiological adaptations and mitochondria play a central role. Whether changes in mitochondrial respiration are seen after exercise in patients with a reduced circulation is unknown. The aim of the study was to evaluate the time course and whether one session of calf raise exercise stimulates mitochondrial respiration in the calf muscle of patients with peripheral vascular disease. Methods One group of patients with peripheral vascular disease (n = 11) and one group of healthy older adults (n = 11) were included. Patients performed one session of continuous calf raises followed by 5 extra repetitions after initiation of pain. Healthy older adults performed 100 continuous calf raises. Gastrocnemius muscle biopsies were collected at baseline and 15 minutes, one hour, three hours and 24 hours after one session of calf raise exercise. A multi substrate (octanoylcarnitine, malate, adp, glutamate, succinate, FCCP, rotenone) approach was used to analyze mitochondrial respiration in permeabilized fibers. Mixed-linear model for repeated measures was used for statistical analyses. Results Patients with peripheral vascular disease have a lower baseline respiration supported by complex I and they increase respiration supported by complex II at one hour post-exercise. Healthy older adults increase respiration supported by electron transfer flavoprotein and complex I at one hour and 24 hours post-exercise. Conclusion Our results indicate a shift towards mitochondrial respiration supported by complex II as being a pathophysiological component of peripheral vascular disease. Furthermore exercise stimulates mitochondrial respiration already after one session of calf raise exercise in patients with peripheral vascular disease and healthy older adults. Trial

    The Project "Black Sea Earthquake Safety Net(work)" ESNET has the intention to educate and raise awareness of seismic risk in the Black Sea Basin in four countries: Moldova, Romania, Bulgaria and Turkey. The project is financed through "The Black Sea Basin Joint Operational Programme", an EU operational programmes under European Neighborhood & Partnership Instrument (ENPI). The programme is financed by ENPI. The participation of Turkey is financed by Instrument for Pre-accession Assistance. It is implemented during the period 2007 - 2013. The project wants to contribute to the prevention of natural disasters generated by earthquakes in Black Sea Basin by developing a joint monitoring and intervention concept. All the countries involved in the project have their own studies, strategies, prevention and intervention systems in case of earthquakes, but until now there has not been an integrated approach so far in the Black Sea Basin. Given the cross-border character of seismic activity, it is necessary to have a cross-border approach on prevention, monitoring and intervention in case of earthquakes. Main objectives : 1. The assessment of the disaster potential, with accent on the seismic risk degree and the earthquakes effects in the intervention area. For achieving the main objective is to have an accurate and up-to-date assessment of the potential of disasters provoked by earthquakes in the project area/regions. This assessment will be carried out at national level and will be used in designing the common concept/approach for dealing with earthquakes at regional level, thus ensuring the cross-border character of the objective. 2.To develop an integrated seismic monitoring and intervention concept. This integrated concept, built on the basis of the previous objective, will have a cross-border relevance and is at the core of the action. The monitoring and intervention in case of earthquakes will be coordinated among the participating countries based on this, thus a

    Muscle force production and power output in active males, regardless of the site of measurement (hand, leg, or back), are higher in the evening than in the morning. This diurnal variation is attributed to motivational, peripheral and central factors, and higher core and, possibly, muscle temperatures in the evening. This study investigated whether increasing morning rectal temperatures to evening resting values, by active or passive warm-ups, leads to muscle force production and power output becoming equal to evening values in motivated subjects. Ten healthy active males (mean ± SD: age, 21.2 ± 1.9 yrs; body mass, 75.4 ± 8 kg; height, 1.76 ± .06 m) completed the study, which was approved by the University Ethics Committee. The subjects were familiarized with the techniques and protocol and then completed four sessions (separated by at least 48 h): control morning (07:30 h) and evening (17:30 h) sessions (with an active 5-min warm-up) and then two further sessions at 07:30 h but proceeded by an extended active or passive warm-up to raise rectal temperature to evening values. These last two sessions were counterbalanced in order of administration. During each trial, three measures of handgrip strength, isokinetic leg strength measurements (of knee flexion and extension at 1.05 and 4.19 rad.s(-1) through a 90° range of motion), and four measures of maximal voluntary contraction (MVC) on an isometric ergometer (utilizing the twitch-interpolation technique) were performed. Rectal and intra-aural temperatures, ratings of perceived exertion (RPE) and thermal comfort (TC) were measured. Measurements were made after the subjects had reclined for 30 min and after the warm-ups and prior to the measurement of handgrip and isokinetic and isometric ergometry. Muscle temperature was taken after the warm-up and immediately before the isokinetic and MVC measurements. Warm-ups were either active (cycle ergometer at 150 W) or passive (resting in a room at 35 °C, relative

    The richness of African soil resources need to be protected for future generations. A number of threats are affecting the functioning of African soils, not only for the purpose of agricultural production, but also for other important environmental services that soil delivers to all of us. This is of particular importance once we know that many health-related problems in Africa are indirectly related to the services of soils. To raise the awareness of the general public, policy makers and other scientists to the importance of soil in Africa, the Joint Research Centre of the European Commission is to produce the first ever Soil Atlas of Africa. This is in collaboration with the African Union Commission, the Food and Agriculture Organization of the United Nations (FAO), the Africa Soil Science Society, ISRIC - World Soil Information and scientists from both Europe and Africa. The Atlas compiles existing information on different soil types as easily understandable maps (both at regional and continental scale) covering the African continent. The Soil Atlas of Africa intends to produce derived maps at continental scale with descriptive text (e.g. vulnerability to desertification, soil nutrient status, carbon stocks and sequestration potential, irrigable areas and water resources) as well as specific maps to illustrate threats such as soil erosion for instance. For each regional overview, large scale examples of soil maps and derived products are presented too. The Atlas will be published as a hardcover book containing 174 A3 pages, which will allow soils maps to be displayed at the A2 scale. Both French and English versions of the Atlas will be edited. The Atlas will be sold at a low cost and will be for free for educational purpose (Schools and Universities). A digital version on CD and eventually freely downloadable on internet will also be available. Together with the publication of the Atlas, associated datasets on soil characteristics for Africa will be made

    Publications on the human impact on peat bogs pay a lot of attention to peat erosion, peat burning and changes in the physical and chemical properties of peat deposits that indicate pollution in the environment, but a more detailed analysis of current changes in the peat bog relief as a result of peat deposit extraction and drying is omitted. Compared to other areas of the world, the level of knowledge on anthropogenic changes in the relief of peat bogs in some areas of Poland may be considered advanced. This applies not only to peat bogs in northern Poland but also southern Poland, where peat bogs in the Carpathians and the Sudetes are also found. The best analyzed peat bogs in southern Poland are the raised bogs in the Orawsko-Nowotarska Basin (Western Carpathians) and in valleys in the Bieszczady Mts. (Eastern Carpathians). Both areas are impacted by deep precipitation shadow. The purpose of this paper is: (1) to assess the rate of shrinkage in the surface area of peat domes in the mentioned areas, (2) to describe the rate of growth in the surface area of older and younger post-peat areas, (3) to explain current changes in peat bogs morphology, (4) to explain changes in water retention in peat deposit, (5) to separate phases in peat bogs relief changes. With that in mind, the direction and rate of change of landforms typical of younger post-peat areas, such as peat extraction scarps, post-extraction hollows, drainage systems including ditches and regulated stream channels, were analyzed. A special emphasis was placed on the period of time when the restoration of such areas has taken place. The paper is based on an analysis of maps produced over the last 230 years as well as on aerial photographs taken since 1965 and on LiDAR data. Fieldwork included the geomorphological and hydrographic mapping of specified landforms within peat bogs using GPS methods. In period prior to human activity peat domes were larger than today and were surrounded by lagg fens and were

    Chufa (Cyperus esculentus L. var. sativus), also known as tiger nut, is a typical crop in the Region of Valencia (Spain). Its tubers are used to produce a beverage called horchata. Chufa has been cultivated traditionally in ridges and furrow irrigated. Currently, the quality of water used is acceptable, there are no limitations on supply, and water is not expensive; therefore, large amounts of water are used. The European Water Framework Directive 2000/60 is based on the precautionary principle, considering preventive action for measures to be taken; thus, water use is an issue to improve. Moreover, drought periods are becoming more frequent and extended, and water is being diverted to other uses. In this two year study (2007-2008), we analysed how yield and irrigation water use efficiency (IWUE) are affected by two cultivation factors: planting strategy and irrigation system. Three planting strategies were analysed: ridges (R) and flat raised beds, with two (B2) and three (B3) plant rows along them, while two irrigation systems were compared, furrow (FI) and drip irrigation (DI). Within the beds, the effect of the position of the plant row was considered, differing among plants grown in the north (n), central (c), and south (s) rows. Distances between ridge and bed axes were 60, 80 and 120 cm for R, B2 and B3, respectively. Irrigation was based on the Volumetric Soil Water Content (VSWC), which was continuously monitored with capacitance sensors (ECH2O EC-5 in FI and multidepth capacitance sensors C-Probe in DI). Each irrigation session started when the VSWC in R dropped to 60% and 80% of field capacity in FI and DI, respectively. Each DI session lasted 60 min in 2007; while in 2008 the installation was automated, stopping each session when the sum of the VSWC at 10, 20, and 30 cm soil depth reached its corresponding field capacity value. With both irrigation systems, beds were irrigated simultaneously with ridges and with the same irrigation duration. Plants from

    Full Text Available El ciclo reproductor de hembras de Tupinambis merianae criadas en ambiente templado consiste de tres fases gonadales: previtelogénica, vitelogénica y postovulatoria o lútea. Durante la fase previtelogénica, que ocupa gran parte del verano, el otoño e invierno, los ovarios son pequeños, pesan menos de 4 g y contienen solamente folículos no vitelogénicos, los cuales se desarrollan lentamente a partir de los nidos germinales, alcanzando unos 5 mm de diámetro. Debido a una maduración gonadal asincrónica entre ambos sexos, las cópulas acontecen cuando los ovarios son aún previtelogénicos. Luego sobreviene una corta e intensa vitelogénesis, durante la cual los folículos crecen uniformemente incrementando unas 6 veces su diámetro (cerca de 30 mm, mientras que la masa ovárica total alcanza unos 400 g. El proceso culmina entre los 15 y 20 días, con una ovulación generalizada y la subsiguiente oviposición. Como consecuencia, los ovarios postovulatorios aparecen reducidos a unos 5 g, con una superficie casi enteramente cubierta de cicatrices foliculares, las cuales pronto desarrollan cuerpos lúteos. La detención del ciclo ovárico, con atresia folicular previtelogénica masiva, como resultado del aislamiento de las hembras, permite concluir sobre la existencia de estímulos sexuales promotores de la vitelogénesis. The reproductive cycle of Tupinambis merianae females raised in a temperate environment consists of three gonadal phases: previtellogenic, vitellogenic and postovulatory or luteal phases. During the previtellogenic phase, which takes great part of the summer, autumn and winter, the ovaries are small, weigh less than 4 g, and contain only nonvitellogenic follicles, which develop slowly from germinal beds, until they are almost 5 mm diameter. Due to an asynchronous gonadal maturation in both sexes, matings occur when ovaries are still previtellogenic. Then comes a short and intense vitellogenesis, during which follicles grow

    Full Text Available This paper argues against the suggestion that governments should push for gender equality more aggressively in order to raise fertility. The paper presents a threefold "no" to this proposal. It takes issue with the goal of raising fertility, arguing that the claims that fertility must be increased are based on myths. It rejects a more aggressive pursuit of gender equality for demographic purposes, maintaining that this method preserves inequality. It warns against using gender equality for fertility purposes, stating that this narrows the realm of gender equality. The paper is based on a debate held at the Max Planck Institute for Demographic Research in Rostock, at which the author was asked to argue against the gender equality-fertility proposal. The other participants in the debate were Laurent Toulemon ("yes", Dimiter Philipov ("no", and Livia Oláh ("yes".

    Computed Tomography Angiogram (CTA) has become a routine part of pre-operative assessment of vascular anatomy and design in perforator flaps. We conducted a retrospective cohort study of flap raised on the deep inferior epigastric system (DIES) at our institution in order to identify CTA signs that might predict venous congestion in these flaps. 98 consecutive patients who had 124 DIES flaps raised from 2008 to 2012 were studied. Of these 124 flaps, four (3.2%) developed venous congestion. Our results showed that a Superficial Inferior Epigastric Vein (SIEV) that is larger than the DIEV at origin is highly predictive of congestion (5.2 vs 3.5 mm, p = 0.007).

    Camponotus is the second largest ant genus and known to harbor the primary endosymbiotic bacteria of the genus Blochmannia. However, little is known about the effect of diet and environment changes on the gut bacterial communities of these ants. We investigated the intestinal bacterial communities in the lab-raised and field-collected ants of Camponotus fragilis which is found in the southwestern United States and northern reaches of Mexico. We determined the difference of gut bacterial composition and distribution among the crop, midgut, and hindgut of the two types of colonies. Number of bacterial species varied with the methods of detection and the source of the ants. Lab-raised ants yielded 12 and 11 species using classical microbial culture methods and small-subunit rRNA genes (16S rRNAs) polymerase chain reaction-restriction fragment-length polymorphism analysis, respectively. Field-collected ants yielded just 4 and 1-3 species using the same methods. Most gut bacterial species from the lab-raised ants were unevenly distributed among the crop, midgut, and hindgut, and each section had its own dominant bacterial species. Acetobacter was the prominent bacteria group in crop, accounting for about 55 % of the crop clone library. Blochmannia was the dominant species in midgut, nearly reaching 90 % of the midgut clone library. Pseudomonas aeruginosa dominated the hindgut, accounting for over 98 % of the hindgut clone library. P. aeruginosa was the only species common to all three sections. A comparison between lab-raised and field-collected ants, and comparison with other species, shows that gut bacterial communities vary with local environment and diet. The bacterial species identified here were most likely commensals with little effect on their hosts or mild pathogens deleterious to colony health. PMID:24748441

    Palawan has the highest malaria endemicity in the Philippines, and malaria remains a major health burden in the region. In 1999, 344 microscopists were trained in Palawan. This allowed for early diagnosis and prompt treatment throughout the island. To take a significant step toward the elimination of malaria on the island, microscopists implemented community awareness-raising activities aimed at preventing transmission of malaria. The objective of the present study was to determine the impact of these activities on the self-implemented preventive measures against malaria by the ex-patients of the microscopists. Structured interviews were carried out from January to February in 2012, in 20 remote malaria-endemic villages throughout Palawan. In total, 141 ex-patients who had previously been diagnosed malaria-positive by the microscopists, volunteered to participate in the present study. Structural equation modeling was conducted to determine factors associated with self-implemented preventive measures against malaria, which included: (1) place of residence; (2) socio-demographic characteristics; (3) knowledge on malaria; (4) participation in community awareness-raising activities for malaria prevention; and (5) satisfaction with microscopists. Structural equation modeling identified six significant factors independently associated with self-implemented preventive measures against malaria; ethnicity, knowledge on malaria transmission, knowledge on vector species, knowledge on vector's most active time, participation in awareness-raising activities for malaria prevention by microscopists, and satisfaction with microscopists. Tagalog ethnicity (the predominant ethnic group) was positively related to better self-implemented preventive measures. In conclusion, aside from providing early diagnosis and treatment, microscopists played a significant role in self-implemented preventive measures against malaria.

  4. Multiple stressors in agricultural streams: a mesocosm study of interactions among raised water temperature, sediment addition and nutrient enrichment.

    Directory of Open Access Journals (Sweden)

    Jeremy J Piggott

    Full Text Available Changes to land use affect streams through nutrient enrichment, increased inputs of sediment and, where riparian vegetation has been removed, raised water temperature. We manipulated all three stressors in experimental streamside channels for 30 days and determined the individual and pair-wise combined effects on benthic invertebrate and algal communities and on leaf decay, a measure of ecosystem functioning. We added nutrients (phosphorus+nitrogen; high, intermediate, natural and/or sediment (grain size 0.2 mm; high, intermediate, natural to 18 channels supplied with water from a nearby stream. Temperature was increased by 1.4°C in half the channels, simulating the loss of upstream and adjacent riparian shade. Sediment affected 93% of all biological response variables (either as an individual effect or via an interaction with another stressor generally in a negative manner, while nutrient enrichment affected 59% (mostly positive and raised temperature 59% (mostly positive. More of the algal components of the community responded to stressors acting individually than did invertebrate components, whereas pair-wise stressor interactions were more common in the invertebrate community. Stressors interacted often and in a complex manner, with interactions between sediment and temperature most common. Thus, the negative impact of high sediment on taxon richness of both algae and invertebrates was stronger at raised temperature, further reducing biodiversity. In addition, the decay rate of leaf material (strength loss accelerated with nutrient enrichment at ambient but not at raised temperature. A key implication of our findings for resource managers is that the removal of riparian shading from streams already subjected to high sediment inputs, or land-use changes that increase erosion or nutrient runoff in a landscape without riparian buffers, may have unexpected effects on stream health. We highlight the likely importance of intact or restored buffer

    Full Text Available Hand-raised rhinos would preferentially settle at sites close to areas where human activity was significant. Hand-raised rhinos that attached themselves to sites of human activity tended to move less widely and to have smaller seasonal ranges than those that moved away from human settlements. These rhinos had no fear of humans and some animals would move along established roads into hostile areas outside the park. These factors made hand-raised rhinos more vulnerable to poaching than their wild counterparts. Management of hand-raised rhinos with regards to ranging behaviour is discussed in the text.

    The successful reintroduction program being run by the Whooping Crane Eastern Partnership using whooping cranes (Grus americana) trained to fly behind ultralight aircraft depends on a supply of these trained crane colts each year. The crane colts are hatched from eggs contributed by the various partners and trained to follow costume clad humans and ultralight aircraft at USGS Patuxent Wildlife Research Center, Laurel, Maryland, USA. After several seasons of raising small numbers of crane colts (7-14), we wanted to increase the number of birds being trained, but were restrained by limits in our facilities. By altering the established husbandry and training program to allow the use of a recently modified facility, we have increased the number of colts raised for this release program. However, we did not know whether the new facility and husbandry regime would significantly alter the behavior of the colts. Therefore, we have begun a two year study to determine if there are differences in the behavior of cranes raised by the two methods, and if any of the differences discovered relate directly to whooping crane survival and migration skills in the release program.

Setting: Armed Forces Hospital, Southern Region, Kingdom of Saudi Arabia. Patients: Adult patients (12 years and older admitted acutely with a sickle cell crisis who consent to taking part in the study. Candidates may re-participate if they are readmitted with a further acute painful crisis. Results: 36 patients with homozygous sickle cell disease consented to take part in the study. D-dimer levels were raised in 31 (68.9% of 45 episodes of painful crisis of whom 13 had an abnormal chest X-ray. Of those with a normal chest X-ray only one patient had a raised D-dimer level: sensitivity of 92.3%, specificity 40.6%, positive predictive value 38.7% and negative predictive value of 92.9% for an abnormal chest X-ray. Conclusion: D-dimer levels are frequently raised during an acute painful crisis. A normal level has a high negative predictive value for an abnormal chest X-ray.

    2007-02-01

    How do seabirds acquire diving skills after fledging? This is an important issue to complete our basic knowledge of life history in seabirds, but the mobility of juveniles obstructs the continuous recording of the development of diving behaviour. In this study, we raised hatchling brown boobies, Sula leucogaster, which are known to have a long post-fledging period. Once boobies began to fly, they made round trips between the sea and the nest, and begged for food from us, their surrogate parents. During this post-fledging care period, the development of diving behaviour was recorded using data loggers. In addition, we attached data loggers to adult brown boobies in the field and compared their diving performance with that of juveniles. The hand-raised juveniles had relatively slow development of diving ability during the first month after fledging. This slow development of behaviour with ontogeny might be the proximate cause for the extended post-fledging care period in this species. This study shows that the combination of bio-logging and hand raising of seabirds is a useful tool for assessing the ontogeny of diving behaviour in these animals.

    Full Text Available Together with three colleagues, I have been asked by the MPIDR to debate the following question: "Should governments in Europe be more aggressive in pushing for gender equality to raise fertility? Setting aside the "lighthearted" side of this "Rostocker Debate," (12 minutes for each speech, one minute for each comment, I saw this as a good opportunity to think about the stakes behind the question. In order to address this complex issue, it is necessary to think about the many "preliminary questions" that we have to ponder before responding: Why should fertility be raised? Are political measures legitimate? Are they efficient? On what basis are we qualified to give "expert" opinions on such a topic? When the question comes to the fore, we as scholars are sometimes asked to provide an answer. It would, of course, be more comfortable not to answer, but our interlocutors (politicians, journalists, teachers, and also funding agencies often want a definite response one way or the other. Even though our position may be a matter of politics as well as a matter of science, we must give an answer. The empirical evidence shows that European countries where gender inequality is lower are also the countries where fertility is the highest. This is the evidence-based response that we can give to that question. European countries need to find a new equilibrium after the end of the baby boom period, when gender equality was very low. In all countries, the empowerment of women is underway, thanks to the economic independence given by work-related income. Increasing gender equality is an efficient way to reduce the opportunity costs of having and raising children, and thus to increase fertility. Finally, "pushing for gender equality" may have many positive effects other than raising fertility, and has few negative side effects. Gender equality is thus a convenient political aim per se; an institutional goal which leaves many political questions open. So, yes, we

    A wide spread disease, which may lead the patient to severe outcomes e.g. pain, loss of joint motion, inflexibility and even disability, is Knee osteoarthritis (OA). It is most common among adults of older age and should not be ignored at all. Literature does not show any clear pathogenesis for occurrence of Knee OA, but most of the indications point toward biomechanical stresses which may influence the articular cartilage and sub chondral bone. Objective: The Aim of this study is to become aware of the effects of physical therapy with and without laterally raised footwear in the management of medial knee osteoarthritis. Methodology: We have used experimental comparative study in 35 patients which were randomly selected from Department of Physiotherapy, Fatima Memorial Hospital, Shadman, Lahore. The study consisted of 2 groups, Group I (Experimental Group): In experimental group, patients were treated with laterally raised foot wear and physical therapy both. Group II (Control Group): Whereas in control group patients were treated by physical therapy alone. Kellgren and Lawrence (KL) scale was used to assess radiograph of the knee joints after an anteroposterior weight-bearing standing. The assessment of disease in patients was done by using the Western Ontario and McMaster Universities (WOMAC) Index, Muscle flexibility, Muscle strengthening and Tolerance scales. Results: In group-I the mean age of patients observed was 59.52+-13.66 years and 65+-12.87 years in Group-II. In Group-I, 9 (52.9%) patients were males and 8 (47.1%) patients were females while in Group-II, 9 patients (50%) were male and 9 (50%) were female. In Group-I 2 (11.8%) patients used flat and open shoes, 6 (35.3%) used flat and close shoe, 3 (17.6%) patients used dress shoes and 2 (11.8%) used flat shoes. In Group-I, the frequency of patients wearing laterally raised foot wear in terms of duration was; 5 (29.4%) patients for 20 days, 4 (23.5%) for 24 days, 4 (23.5%) for 25 days, whilst 2 patients

    A wide range of swine husbandry practices prevail in Romania: pork for human consumption is derived from hunting wild boar, from household rearing of small numbers of backyard pigs, and from indoor, industrial production of swine raised in confinement indoors. Romania thus represents an instructive place for evaluating the influence of animal management on the exposure risk of the zoonotic parasite, Toxoplasma gondii. The fact that many Romanians eat uncooked or undercooked pork, especially when raised for household consumption, elevates the public health imperative to understand these risks. The aim of the study, therefore, was to evaluate the seroprevalence of T. gondii in pigs and wild boars from Romania. During 2008-2010, we collected 3,595 serum samples from pigs (fattening pigs, sows, backyard pigs) and 150 serum samples from wild boars. The sera were assayed by immunofluorescence antibody test (cutoff, 1:32) for antibodies against T. gondii. The overall seroprevalence of T. gondii infection was 23.1 % (829/3,595) in pigs and 16 % (24/150) in wild boars. The seroprevalence was significantly higher (p pigs (30.5 %; 783/2,564) than in sows (12.4 %; 46/371) or fattening pigs (none of the sera was positive). The management system (indoor pigs versus backyard pigs) represented the most important factor in the epidemiology of T. gondii infection. The proximity of backyard pigs to the definitive host of this parasite (cats), as well as their access to contaminated meat products, elevated their exposure risk well above that of pigs raised in confinement, and even above that of wild boars inhabiting sylvatic environments.

    Plastic tarps are commonly used in raised bed strawberry production to minimize emissions of preplant soil fumigants and are left in place throughout the growing season as part of the standard cultural practices. Soil amendments with chemicals such as thiosulfate (S2O3(2-)) can reduce fumigant emissions. A field study was conducted near Santa Maria, CA to determine the effects of low density polyethylene (LDPE) and virtually impermeable film (VIF) over raised-beds and applying potassium thiosulfate (KTS) in furrows on reducing chloropicrin (CP) emissions from a strawberry field. Four fields (or treatments) were tested with 224 kg ha(-1) CP drip-applied threecm under the soil surface. The CP flux from bed tops and furrows and gas-phase concentrations under the tarps were monitored for five d. The CP emission flux and concentration under tarp were highest immediately following application. Diurnal temperature change affected CP concentration and emission fluxes (higher values during the day and lower at night). Slightly higher CP cumulative emission occurred using LDPE tarp (19%) compared to VIF (17%). Normalized flux (CP emission flux from the beds divided by CP concentration under the tarp) being estimated from field measurement was slightly higher for LDPE than VIF indicating different tarp permeability in the field. Because of extremely low emissions from the furrows (emission loss), KTS application to furrow treatments did not show further emission reductions than non-KTS treatments. This indicates that emission reduction should focus on the tarp above raised-beds when fumigant was drip-applied near bed-surface.

    Full Text Available This study was conducted to determine the effect of microbial or antimicrobial additives on the performance and organ morphology of broilers raised in batteries or in floor pens. The effect of microbial additives on the presence of oocysts in the litter was also studied. Experiments 1 and 2 consisted of four treatments (non-supplemented control diet or diet supplemented with avilamycin, bacitracin methylene disalicylate or enramycin and six repetitions in a randomized block design. In Experiment 1, 288 day-old chicks were housed in heated batteries in a environmentally controlled room, 12 chicks per cage; in Experiment 2, 1,200 day-old chicks were housed in a curtain-sided experimental house, with concrete floor and rice hulls as litter material, 50 chicks per pen. Experiments 3 and 4 were carried out similarly to Experiments 1 and 2, respectively, but the treatments consisted of microbial additives (non-supplemented control diet or Bacillus subtilis added to the feed plus Lactobacillus reuteri and Lactobacillus johnsonii added to the water, undefined microflora added to the water or live yeast added to the feed. The antibiotics did not affect the performance of birds raised in batteries, but improved feed conversion, weight gain and live weight when chickens were kept on the floor pens. Microbial additives did not affect bird performance in any environment; however, treatments affected liver weight. Microbial agents increased intestinal weight in floor-raised broilers. No relationship was seen between the use of microbial additives and the presence of oocysts in the litter.

    In the present study, we investigated the effect of age in the haptic horizontal-vertical curvature illusion from adolescence to old age. Blindfolded participants explored raised-line convex curves with one finger and two fingers (Experiment 1). They judged the size of the curves (horizontal/vertical), using two sliding rulers. The results suggest that young and older haptic explorers overestimated the vertical. Adolescents did not show the haptic illusion. In Experiment 2, adolescents performed the task visually showing a stronger horizontal-vertical illusion. The findings suggest that the illusion develops later in touch than in vision. The theoretical implications of the results are discussed.

    High ambient temperature is a major problem in commercial broiler production in the humid tropics because high producing broiler birds consume more feed, have higher metabolic activity, and thus higher body heat production. To evaluate the effects of two previously isolated potential probiotic strains ( Lactobacillus pentosus ITA23 and Lactobacillus acidophilus ITA44) on broilers growing under heat stress condition, a total of 192 chicks were randomly allocated into four treatment groups of 48 chickens each as follows: CL, birds fed with basal diet raised in 24 °C; PL, birds fed with basal diet plus 0.1 % probiotic mixture raised in 24 °C; CH, birds fed with basal diet raised in 35 °C; and PH, birds fed with basal diet plus 0.1 % probiotic mixture raised in 35 °C. The effects of probiotic mixture on the performance, expression of nutrient absorption genes of the small intestine, volatile fatty acids (VFA) and microbial population of cecal contents, antioxidant capacity of liver, and fatty acid composition of breast muscle were investigated. Results showed that probiotic positively affected the final body weight under both temperature conditions (PL and PH groups) compared to their respective control groups (CL and CH). Probiotic supplementation numerically improved the average daily gain (ADG) under lower temperature, but significantly improved ADG under the higher temperature ( P Lactobacillus strains significantly increased the expression of the four sugar transporter genes tested (GLUT2, GLUT5, SGLT1, and SGLT4) indicating probiotic enhances the absorption of this nutrient. Similar but less pronounced effect was also observed under higher temperature (35 °C) condition. In addition, the probiotic mixture improved bacterial population of the cecal contents, by increasing beneficial bacteria and decreasing Escherichia coli population, which could be because of higher production of VFA in the cecum, especially at heat stress condition.

    Background Pulmonary arterial systolic pressure (PASP) can be estimated with transthoracic echocardiography. However, the significance of raised PASP on routine echocardiography is uncertain. In this study, we evaluated the mortality and hospitalization rates of subjects with raised PASP in a cohort of patients referred directly by their general practitioners for routine outpatient (open access)echocardiography for further analysis of suspected heart failure. Results A total of 485 subjects were referred for open access echocardiography at our hospital in 2002. A cohort of 209/485 (43%) consecutive subjects with measurable tricuspid regurgitation were followed for a minimum of five years investigating hospitalization rates and survival. Some 62 of 209 (30%) subjects had pulmonary hypertension (PH). Subjects with PH were significantly more likely to have four or more hospital admissions (22% vs. 8%; P 30 days of cumulative hospital stay over five years (29% vs. 13%; P < 0.01). PH was significantly associated with mortality (P = 0.003),Records from the Office of National Statistics revealed that subjects with PH were more likely to have chronic lung diseases recorded as immediate or contributory causes of death (50% vs. 14%; P < 0.05). Conclusions PASP ≥ 36 mmHg on routine echocardiography is associated with recurrent hospital admissions, prolonged hospitalizations and increased cause of mortality. Therefore, the diagnosis of PH on echocardiography deserves further clinical evaluation, with future studies designed at defining a suitable diagnostic strategy.

    In Swiss mice sustained energy intake (SusEI during peak lactation has been previously suggested to be constrained by the capacity of the mammary glands to produce milk, supporting the “peripheral limitation” hypothesis. Here we experimentally examined if SusEI in these mice was not only limited peripherally but also constrained by the ability to dissipate heat. Female Swiss mice were provided with additional offspring above their natural litter sizes and were maintained during lactation either in warm (23°C or cold (5°C conditions. Food intake, thermogenesis, litter size and mass, and the weight of the mammary glands were measured. No differences were observed in asymptotic food intake at peak lactation, litter mass and thermogenesis between females raising litters of different size. Cold-exposed females increased food intake and thermogenic capacity, but weaned significantly smaller and lighter litters with smaller pup sizes compared with females in warm conditions. The weight of the mammary glands did not differ between warm and cold-exposed females, but within temperatures was positively related to litter mass. These data suggested that cold exposure increased food intake, but had no effect on the capacity of the mammary glands to secret milk because they were already working maximally in the females raising larger litters. The factors causing this limit in the mammary capacity remain elusive.

    Full Text Available Theatre, which has served certain ends since it came into existence, mostly strives to make changes in the traditional structure through its effective power of expression. This branch of art has acquired a privilege with its educational priority in the realisation of smooth and natural flow of the social transition which takes place during the journey from the traditional to the universal with political, religious as well as economic concerns.From the ancient times to the present, attempts to educate society through theatre have assumed a considerably potential role as a means employed in circumstances where dominant systems of thought were intended to be disseminated into broad areas. However, in spite of its unifying role within the social life, theatre has not only undertaken the appropriate messages, but it has also served the ends to impose some tendencies aimed to meet interests, leading to social hesitations against arts. This artistic activity, which has been sacrificed for the sake of conflicts of interest, has been isolated from the social life by the minds that regard enlightenment of the society through awareness-raising as a threat.This study, through “The Model of Vital Quality Acquisition by Investing in Arts”, puts an emphasis on the social tendency to display sensitivity to arts as a result of the communication between educational awareness and investment in arts as well as the development of understanding on aesthetic arts, and dwells on the role and importance of theatre in raising social awareness.dissemine [disseminated

    Ambiguous findings during external examination of a deceased in combination with dubious autopsy findings can raise doubts concerning the manner and cause of death. We report the case of a 35-year-old female deceased who had suffered from a borderline personality and depressive disorder with suicidal ideation. At the death scene, the body showed massive facial swelling accompanied by complete reddening of the skin of the face, with patchy skin abrasions on the forehead and neck, and purple bruise-like discolorations distributed symmetrically over both shoulders, elbows, hands, hips, knees, lower legs, and feet, raising the suspicion of underlying massive external blunt force injury. Police investigators strongly suspected sexual homicide. At autopsy, dissection in layers revealed massive subcutaneous hemorrhages as the cause of the reddish skin discolorations. Toxicological analyses showed fatal levels of lamotrigine with additional proof of zopiclone, zolpidem, diphenhydramine, O-desmethylvenlafaxine, pregabalin, tramadol, and modafinil in venous blood. Histologically, both the macroscopically impressive purple skin changes with underlying bleeding into the subcutaneous tissue and the skin abrasions were due to leukocytoclastic vasculitis, a form of acute hypersensitivity vasculitis that was a reaction to the multiple therapeutic drugs that the woman had taken shortly before death. The manner of death was classified as suicide, and sexual homicide was ruled out. PMID:25957602

  5. Reproductive status and synchronization of oestrus for predetermined insemination of Philippine carabaos (swamp buffalo) raised by smallholder farmers

    International Nuclear Information System (INIS)

    There is an urgent need to improve size, and meat and milk productivity of the Philippine carabao, a swamp type of water buffalo (Bubalus bubalis), through crossbreeding with the riverine type. Studies were conducted to assess the reproductive status of carabaos raised by smallholder farmers, determine conception rates of buffaloes to artificial insemination (AI) through oestrus synchronization, and examine the patterns of plasma progesterone in cyclic and acyclic carabao heifers. Approximately 20% of carabaos raised by smallholder farmers were diagnosed pregnant by rectal palpation. This low pregnancy rate may be due to a combination of factors such as the failure to submit for examination carabaos exhibiting external signs of pregnancy, the deliberate postponement of breeding for working females, the inability of bulls to gain access to carabaos in oestrus which are tethered at night, or the high incidence of anoestrus or suboestrus. The reproductive problems in non-pregnant animals were cystic (19.5%), infantile (25.7%), and dormant ovaries (51.3%), and pathology of the uterus and cervix (3.5%). Both feeding and management practices in different locations influenced the nutritional status of female carabaos examined. Animals in good body condition were either cycling or pregnant. A 30-40% conception rate was achieved by synchronization of oestrus and insemination with frozen semen at 72 and 96 h later. Based on progesterone radioimmunoassay and rectal palpation of the ovaries, anoestrus in carabao heifers was due either to a failure of cycling animals to exhibit oestrus or those with inactive ovaries.

    At local level, public support has proven crucial to the implementation of CO2 capture and storage (CCS) demonstration projects. Whereas no method exists to guarantee public acceptability of any project, a constructive stakeholder and community engagement process does increase the likelihood thereof. This deliverable is a follow-up to deliverable D8.1 'Social site characterisation'. Social site characterisation can be used as an instrument to explore, plan and evaluate a process of active and constructive local stakeholder and citizen engagement in a prospective CCS project as a parallel activity to technical site characterisation. It serves as an analytical tool to describe the local social circumstances in the area and to design and evaluate stakeholder and community engagement efforts with the aims of building trust and raising public awareness. Using results from the social site characterisation of the area, the present deliverable focuses on the second purpose. It presents results from public engagement activities designed to raise public awareness and inform public opinion of a prospective CCS site in Poland (onshore) and the UK (offshore): focus conferences. Furthermore, by initiating an enhanced cooperation in planning of new storage sites between project developers, authorities and the local public, focus conferences aim to serve as a 'hinge' between social site characterisation as a research effort and application to real-life project settings. The focus conferences are part of a range of public engagement activities including the setup of public information websites on generic and site-specific CCS, information meetings. A second survey eventually shall evaluate the results of the public engagement activities. The aim of the focus conferences was to raise public awareness and assist public opinion forming processes of a prospective CCS site in Poland (onshore) and the UK (offshore). At the same time, it aimed to present and test a

    Oxygen uptake kinetics (τVO2) are slowed when exercise is initiated from a raised metabolic rate. Whether this reflects the recruitment of muscle fibres differing in oxidative capacity, or slowed blood flow (Q) kinetics is unclear. This study determined τVO2 in canine muscle in situ, with experimental control over muscle activation and Q during contractions initiated from rest and a raised metabolic rate. The gastrocnemius complex of nine anaesthetised, ventilated dogs was isolated and attached to a force transducer. Isometric tetanic contractions (50 Hz; 200 ms duration) via supramaximal sciatic nerve stimulation were used to manipulate metabolic rate: 3 min stimulation at 0.33 Hz (S1), followed by 3 min at 0.67 Hz (S2). Circulation was initially intact (SPON), and subsequently isolated for pump-perfusion (PUMP) above the greatest value in SPON. Muscle VO2 was determined contraction-by-contraction using an ultrasonic flowmeter and venous oximeter, and normalised to tension-time integral (TTI). τVO2/TTI and τQ were less in S1SPON (mean ± s.d.: 13 ± 3 s and 12 ± 4 s, respectively) than in S2SPON (29 ± 19 s and 31 ± 13 s, respectively; P < 0.05). τVO2/TTI was unchanged by pump-perfusion (S1PUMP, 12 ± 4 s; S2PUMP, 24 ± 6 s; P < 0.001) despite increased O2 delivery; at S2 onset, venous O2 saturation was 21 ± 4% and 65 ± 5% in SPON and PUMP, respectively. VO2 kinetics remained slowed when contractions were initiated from a raised metabolic rate despite uniform muscle stimulation and increased O2 delivery. The intracellular mechanism may relate to a falling energy state, approaching saturating ADP concentration, and/or slowed mitochondrial activation; but further study is required. These data add to the evidence that muscle VO2 control is more complex than previously suggested. PMID:24469073

    In July 2002, Catholic Health West (CHW) established a policy that called for a uniform measurement and improvement of community benefit work that would preserve the flexibility of each facility to respond to the needs of its particular community. CHW's 40 member hospitals were asked to submit two community benefit goals that would be monitored for outcomes over the subsequent two years. The system's corporate office helped staff members at each facility determine the baseline for performance improvement, set realistic goals, establish measurable outcomes, and develop an effective intervention strategy for the health issue addressed. The goals, set forth in CHW's Community Benefit Policy and its Standards for Mission Integration, were included as part of each hospital president's annual performance evaluation. At the end of the third year of CHW's effort to apply greater scientific rigor to community benefit programming, more than 85 percent of its hospitals met or exceeded their stated goals.

  20. Optimization of the procedure of cholecystography per os in children as a method of raising its diagnostic informative value

    International Nuclear Information System (INIS)

    Methods of performance of unified cholecystograhy per os were developed on the basis of the results of X-ray and ultrasonic investigations of the gall bladder in 168 children. A method of contrast medium dosage to raise the informative value of cholecystography was proposed. A procedure of taking pictures with a patient lying in a prone position, an X-ray tube being turned in accordance with an angle of gall bladder inclination to the anterior abdominal wall, was worked out, making it possible to detect, with a high degree of reliability, the most common development defects of the gall bladder and to define its true sizes on the basis of X-ray findings
