    We describe a case of stump appendicitis with the formation of abdominal abscesses in a 41-year-old patient 10 years prior appendectomy. The patient consulted with fever (38.1 °C) and abdominal pain, located at the right iliac fossa. Imaging studies showed signs of abscesses, located at the right iliac fossa, without clear origin of these abscesses. The abscesses were drained through diagnostic laparoscopy, no bowel perforation or clear origin of the abscedation was found during laparoscopy. During postoperative stay, the inflammatory parameters rose and the abscesses reoccurred. Re-laparoscopy was performed, the abscesses were drained and on careful inspection and adhesiolysis, a perforated stump appendicitis was revealed, covered underneath layers of fibrous tissue. Stump appendicitis is a rare complication seen after appendectomy and is generally not considered a possible etiology in patients presenting with fever and right iliac fossa abdominal pain with a history of appendectomy. This often delays the correct diagnosis and results in an associated increased incidence of complications. We describe a case of stump appendicitis occurring 10 years after initial appendectomy.

    Full Text Available Abstract Background Allergy is a serious and apparently increasing public health problem yet relatively little is known about the types of allergy seen in routine tertiary practice, including their spatial distribution, co-occurrence or referral patterns. This study reviewed referrals over an eleven year period to a regional allergy clinic that had a well defined geographical boundary. For those patients confirmed as having an allergy we explored: (i differences over time and by demographics, (ii types of allergy, (iii co-occurrence, and (iv spatial distributions. Methods Data were extracted from consultant letters to GPs, from September 1998 to September 2009, for patients confirmed as having an allergy. Other data included referral statistics and population data by postcode. Simple descriptive analysis was used to describe types of allergy. We calculated 11 year standardised morbidity ratios for postcode districts and checked for spatial clustering. We present maps showing 11 year rates by postcode, and 'difference' maps which try to separate referral effect from possible environmental effect. Results Of 5778 referrals, 961 patients were diagnosed with an allergy. These were referred by a total of 672 different GPs. There were marked differences in referral patterns between GP practices and also individual GPs. The mean age of patients was 35 and there were considerably more females (65% than males. Airborne allergies were the most frequent (623, and there were very high rates of co-occurrence of pollen, house dust mite, and animal hair allergies. Less than half (410 patients had a food allergy, with nuts, fruit, and seafood being the most common allergens. Fifteen percent (142 had both a food and a non-food allergy. Certain food allergies were more likely to co-occur, for example, patients allergic to dairy products were more likely to be allergic to egg. There were age differences by types of allergy; people referred with food allergies were

    PURPOSE OF THE STUDY Total joint replacement is one of the options in surgical treatment of advanced ankle arthritis. It allows the ankle to remain mobile but, unfortunately, it does not provide the same longevity as total knee or hip replacements. Therefore, decisions concerning the kind of treatment are very individual and depend on the clinical status and opinion of each patient. MATERIAL AND METHODS A total of 132 total ankle replacements were carried out in the period from 2004 to 2015. The prostheses used included the Ankle Evolutive System (AES) in 52 patients, Mobility Total Ankle System (DePuy) in 24 patients and, recently, Rebalance Total Ankle Replacement implant in 53 patients. Three patients allergic to metal received the Taric prosthesis. Revision arthroplasty using the Hintegra prosthesis was carried out in four patients. The outcome of arthroplasty was evaluated on the American Orthopaedic Foot and Ankle Society (AOFAS) scoring scale. Indications for total ankle arthroplasty included post-traumatic arthritis in 83 patients, rheumatoid arthritis in 37 and primary arthritis in 12 patients. There were 78 women and 54 men, with an average age of 55.6 years at the time of surgery. RESULTS The average follow-up was 6.1 years (1-11 years). The average AOFAS score of the whole group increased from 33.2 before surgery to 82.5 after it. The primary indication had an important role. Arthroplasty outcomes were poorer in patients with post-traumatic arthritis than in those with rheumatoid arthritis or primary arthritis. In patients with post-traumatic arthritis, the average AOFAS score rose to 78.6 due to restricted motion of the ankle, and some patients continued to have pain when walking. The average AOFAS score in a total of 49 patients who had rheumatoid arthritis or primary arthritis reached a value of 86.4. Post-operative complications were recorded in ten patients (7.6%) in whom part of the wound was healing by second intention. Ossification was also a

    Full Text Available The aim of this study is to establish the time and period of development of Analogical Reasoning (AR and evaluate its independence and performance with respect to the age. We performed a longitudinal cohort study of two age groups and six annual follow-up phases from each one (2000-2005, 2001-2006 in six to eleven years-old children in the city of Huanuco (Peru with a sample of 167 children (first stage, and N=121 (sixth stage. The Raven’s progressive matrices test, coloured version, was applied individually without time limits. Results indicate that AR development occurs in a constant and late way from seven to eleven years-old children, and also that there is independence between the ability of AR and the children age. We discuss the importance of knowledge in the relationships between analogies topics, adjusted to the age, as a mediating factor in the development of AR.

    In the Netherlands, first permanent molars with idiopathic enamel disturbances (IED) are called cheese molars. Though concern is expressed about their prevalence, adequate figures on the subject are missing. The porous enamel of cheese molars can be very sensitive to cold air and can decay rapidly. The aim of the present study was to investigate the prevalence in eleven-year-old Dutch children of cheese molars (IED). During an epidemiological study performed in four cities in the Netherlands, the first permanent molars and central incisors of eleven-year-old children were examined for hypoplasia, opacities, posteruptive enamel loss, premature extraction, and atypical restorations. The observation of a hypoplasia excluded the possibility of cheese molar. A total of 497 children were examined. Six percent (n = 128) of the molars (n = 1988) showed signs of IED (cheese molars), 10 percent of the children had cheese molars of which 8 percent two or more. Incisors (4 percent) with opacities were found in 3 percent in combination with two or more cheese molars. Among the four cities, no significant differences in occurrence were found. The results of this study showed that in 10 percent of the Dutch children eleven years of age, cheese molars (IED) were found. The cause for the phenomenon called cheese molars appears to be child centered. Further studies on prevalence, causes and prevention are mandatory.

    Changes in ozone, temperature, and other minor constituents resulting from eleven year variations in the solar flux between 180 and 340 nm are presented. Results were computed using a one-dimensional time dependent model that allows for all major feedbacks and time delays which may result from changing photolysis rates in the O/sub x/--NO/sub x/--HO/sub x/--ClO/sub x/ system. Since the 1950's the chlorine content of the stratosphere has been increasing. The effect of this increase on ozone variability during the last two solar cycles is analyzed. Expected variations in O 3 and temperature resulting from changes in the uv flux are compared to available measurements

    627 cases of gastric cancer treated surgically during the last 5 years, at the Hospital Nacional "Edgardo Rebagliati Martins" from Instituto Peruano de Seguridad Social (Lima-Perú) were revised. 4 of the patients had been operated before of hemigastrectomy or antrectomy with pyloroplasty for peptic ulcer. The time between the first operation and diagnosis of cancer of the gastric stump was more than 20 years. 3 of these cases were able to be resected. The international incidence of cancer in the gastric stump is 1.1% to 9.2% according to different authors. The risk is higher after 15 years. In the pathogenesis are advocated the lower gastric acidity, biliary reflux, the presence of bacteria, the formation of nitrosamines, intestinal metaplasia, etc. Is necessary to perform periodic endoscopic survey in patients who were treated surgically of peptic ulcer with antrectomy or hemigastrectomy with more than 15 years of evolution.

    : gastric ulcer in 855 (21.5%); duodenal ulcer in 878 (22.1%); gastric and duodenal ulcer in 124 (3.1%), erosive, atrophic gastritis and functional dyspepsia in 2055 (51.8%); and other findings (e.g., MALToma, patients who wanted to receive the therapy even though they had no abnormal endoscopic finding) in 57 (0.5%). The overall eradication rate of the 2 wk standard first-line triple regimen was 86.5%. The annual eradication rates from 2000 to 2010 were 86.7%, 85.4%, 86.5%, 83.3%, 89.9%, 90.5%, 88.4%, 84.5%, 89.1%, 85.8%, and 88.3%, sequentially (P = 0.06). No definite evidence of a significant change in the eradication rate was seen during the past eleven years. The eradication rates of second-line therapy were 88.9%, 82.4%, 85%, 83.9%, 77.3%, 85.7%, 84.4%, 87.3%, 83.3%, 88.9%, and 84% (P = 0.77). The overall eradication rate of 1 wk quadruple second-line therapy was 84.7%. There was no significant difference in the eradication rate according to the H. pylori associated diseases. CONCLUSION: This study showed that there was no trend change in the H. pylori eradication rate over the most recent 11 years in our institution. PMID:23236238

    The use of stump and root wood chips has increased very rapidly in the 21st century in Finland: in the year 2000, the total consumption of stump wood chips for energy generation was 10 GWh, while in 2008 it was around 1.2 TWh. Metsaeteho Oy and TTS Research tested two new stump-lifting devices for lifting stumps in a final felling Norway spruce (picea abies) stand. In the time study with the Vaekevae Stump Processor lifting head, the productivity of stump lifting was 7,5 m3 / E{sub 0}-hour when lifting spruce stumps with a diameter of 30 cm from clayey soil, and 8.3 m3 /E{sub 0}-hour when lifting spruce stumps from sandy soil. When lifting stumps with a diameter of 40 cm, the stump-lifting productivity was 9.0 m3 /E{sub 0}-h (clay) and 10,5 m3 / E{sub 0}-h (sand). The results of this relatively restricted test indicated that the Vaekevae Stump Processor is s reliable and effective stump-lifting head that enables the harvesting of high-quality stump raw material for energy generation. The stump lifting productivity of the other lifting head (Jaervinen) was lower than that of the Vaekevae Strump Processor. Some development suggestions for the Jaervinen lifting head were presented and discussed. (orig.)

    During a period of 17 years, between 1961 and 1977, 59 cases of the cervical stump cancer were treated at NIRS Hospital. We could not epidemically find the difference between the cervical stump cancer and the cervical cancer. 5-year survival rate of cervical stump cancer was 90% in stage I, 86% in stage II, and 63% in stage III, respectively. These results show higher 5-year survival rates, compared with those of cervical cancer. The frequencies of radiation complication in rectum and bladder were lower in the case of cervical stump cancer than in cervical cancer. It was suggested that the optimal radiation dose for cervical stump cancer was 80 - 90 TDF at point A. (author)

    Research on the long-term persistence of effects of interventions aimed at smoking cessation is limited. This paper examined the quitting behavior of individuals who were randomized to a smoking cessation intervention (SI) or to usual care (UC), at a point approximately 11 years later. The initial sample consisted of 5,887 adult smokers in 10 clinics who had evidence of airways obstruction. Two-thirds of the original participants were offered an intensive 12-week smoking cessation intervention. Of these, 4,517 were enrolled in the long-term follow-up study. Randomized group assignment was a strong predictor of smoking behavior after 11 years, in that 21.9% of SI participants and only 6.0% of UC participants maintained abstinence throughout the interval. Logistic regressions identified covariates associated with abstinence. A higher proportion of abstinence was observed in participants that had been assigned to SI (OR = 4.45), were older (OR = 1.11, increment 5 years), had more years of education (OR = 1.05), and fewer cigarettes/day at baseline (OR = 0.90, increment 10 cigarettes). Smokers exposed to an aggressive smoking intervention program and who sustain abstinence for a five-year period are very likely to still be abstinent after 11 years.

    2012-01-01

    Trends in concentration and loads of acetochlor, alachlor, and metolachlor and their ethanasulfonic (ESA) and oxanilic (OXA) acid degradates were studied from 1996 through 2006 in the main stem of the Iowa River, Iowa and in the South Fork Iowa River, a small tributary near the headwaters of the Iowa River. Concentration trends were determined using the parametric regression model SEAWAVE-Q, which accounts for seasonal and flow-related variability. Daily estimated concentrations generated from the model were used with daily streamflow to calculate daily and yearly loads. Acetochlor, alachlor, metolachlor, and their ESA and OXA degradates were generally present in >50% of the samples collected from both sites throughout the study. Their concentrations generally decreased from 1996 through 2006, although the rate of decrease was slower after 2001. Concentrations of the ESA and OXA degradates decreased from 3 to about 23% yr. The concentration trend was related to the decreasing use of these compounds during the study period. Decreasing concentrations and constant runoff resulted in an average reduction of 10 to >3000 kg per year of alachlor and metolachlor ESA and OXA degradates being transported out of the Iowa River watershed. Transport of acetochlor and metolachlor parent compounds and their degradates from the Iowa River watershed ranged from <1% to about 6% of the annual application. These trends were related to the decreasing use of these compounds during the study period, but the year-to-year variability cannot explain changes in loads based on herbicide use alone. The trends were also affected by the timing and amount of precipitation. As expected, increased amounts of water moving through the watershed moved a greater percentage of the applied herbicides, especially the relatively soluble degradates, from the soils into the rivers through surface runoff, shallow groundwater inflow, and subsurface drainage.

    Based on measurements of GOME on ESA ERS-2, SCIAMACHY on ESA-ENVISAT, and Ozone Monitoring Instrument (OMI) on the NASA EOS-Aura satellite there is now a unique 11-year dataset of global tropospheric nitrogen dioxide measurements from space. The retrieval approach consists of two steps. The first step is an application of the DOAS (Differential Optical Absorption Spectroscopy) approach which delivers the total absorption optical thickness along the light path (the slant column). For GOME and SCIAMACHY this is based on the DOAS implementation developed by BIRA/IASB. For OMI the DOAS implementation was developed in a collaboration between KNMI and NASA. The second retrieval step, developed at KNMI, estimates the tropospheric vertical column of NO2 based on the slant column, cloud fraction and cloud top height retrieval, stratospheric column estimates derived from a data assimilation approach and vertical profile estimates from space-time collocated profiles from the TM chemistry-transport model. The second step was applied with only minor modifications to all three instruments to generate a uniform 11-year data set. In our talk we will address the following topics: - A short summary of the retrieval approach and results - Comparisons with other retrievals - Comparisons with global and regional-scale models - OMI-SCIAMACHY and SCIAMACHY-GOME comparisons - Validation with independent measurements - Trend studies of NO2 for the past 11 years

    Full Text Available Background Prolonged use of computers can lead to complications such as eye strain, eye and head aches, double and blurred vision, tired eyes, irritation, burning and itching eyes, eye redness, light sensitivity, dry eyes, muscle strains, and other problems. Objectives The aim of the present study was to evaluate visual problems and major symptoms, and their associations among computer users, aged between 11 and 18 years old, residing in the Qazvin city of Iran, during year 2010. Patients and Methods This cross-sectional study was done on 642 secondary to pre university students who had referred to the eye clinic of Buali hospital of Qazvin during year 2013. A questionnaire consisting of demographic information and 26 questions on visual effects of the computer was used to gather information. Participants answered all questions and then underwent complete eye examinations and in some cases cycloplegic refraction. Visual acuity (VA was measured with a logMAR in six meters. Refraction errors were determined using an auto refractometer (Potece and Heine retinoscope. The collected data was then analyzed using the SPSS statistical software. Results The results of this study indicated that 63.86% of the subjects had refractive errors. Refractive errors were significantly different in children of different genders (P < 0.05. The most common complaints associated with the continuous use of computers were eyestrain, eye pain, eye redness, headache, and blurred vision. The most prevalent (81.8% eye-related problem in computer users was eyestrain and the least prevalent was dry eyes (7.84%. In order to reduce computer related problems 54.2% of the participants suggested taking enough rest, 37.9% recommended use of computers only for necessary tasks, while 24.4% and 19.1% suggested the use of monitor shields and proper working distance, respectively. Conclusions Our findings revealed that using computers for prolonged periods of time can lead to eye

    The purpose of this survey was to identify the number and characteristics of caries risk assessment/treatment (CRA/ Tx) programs in U.S. dental schools in 2009 and compare the results to those of the 1998 survey. A survey of U.S. dental schools was conducted in 2009 using the same eleven-question survey instrument as in 1998. Results were analyzed using stratified random sampling and chi-square tests for six of the questions. Additionally, data from the other questions were directly compared. Two questions showed a statistically significant difference: an increase in programs supervised by one school department and the number of schools using CRA as a graduation requirement. Positive changes are occurring in the development of CRA/Tx programs in U.S. dental schools. A wide variety of approaches to teaching this subject, including use of terminology and treatment philosophies, is evident. The evolution of this subject has been slow and varied over the past eleven years. Changing from a mainly surgical approach model to a medical model is occurring, but a more integrated method is needed to clarify terminology, diagnosis, treatment, and communications with researchers, clinicians, teachers, patients, and third-party payers.

  3. A retrospective study of the epidemiology of leprosy in Cebu: an eleven-year profile.

    Full Text Available Cebu has been one of the most leprosy endemic areas in the Philippines. Despite the high coverage rates of multiple drug therapy (MDT and high BCG-vaccine coverage in children, leprosy control authorities believe that leprosy transmission and incidence (as evidence by continuing new case detection in both adults and children have not declined as expected, once leprosy had been eliminated. In response to the concerns communicated by the authorities regarding ongoing leprosy transmission in Cebu, this study aims to examine the evidence for the hypothesized ongoing transmission, both in children and adults. Furthermore, it will be assessed which groups and areas are experiencing a continuing risk of leprosy infection; this can form a starting point for more targeted approaches to leprosy control.Case records from 2000-2010 were retrospectively collected from the Leonard Wood Memorial Clinic archives, and all other clinics on the island where leprosy was treated. Between 2000 and 2010, 3288 leprosy cases were detected. The overall five year case notification rate (CNR dropped significantly from 47.35 (2001-2005 to 29.21 cases (2006-2010 per 100.000 population. Smaller CNRs were reported for children; however the decline in child-CNR over the same period was minimal. Furthermore, no increase in median age of notification in children or adults was found between 2000 and 2010. Population-adjusted clustering of leprosy cases was mainly detected in urban and peri-urban areas.Although the overall CNR declined significantly, CNR seems to be rather static in lower risk populations and areas. Cases are mainly found in urban areas, however CNRs in these areas decline at a much faster rate than in the lower endemic rural areas. A similar situation was found when comparing adults and children: CNRs observed in children were lower than in adults, but further decline (and elimination of these childhood CNRs was found to be difficult. Moreover, the median age of

This study aims to analyze the monitoring of area to exposure rate from 2002 to 2012, comparing periods of suspended operation of OTU and identifying the influences of CTM and of the radioactive waste deposit, from other facilities of OTU. A total of 22,294 samples were analyzed for area dose rates; average values were obtained of 6.74 μSv h{sup -1} with an amplitude from 0 to 420 μSv h{sup -1}. 92% of the monitoring were below the derivative limit for workers, and 1,702 monitoring samples showed values above this limit. Ignoring the monitoring that was realized at CTM and at the deposit of radioactive waste, the number of monitoring samples were reduced to 1,341. In this case, the average reduces to 0.96 μSv h{sup -1}, going from 0 to 25 μSv h{sup -1}, only 15 samples remained above the threshold for workers and 675 samples were below the limit for individual public. It can be concluded that the OTU is an installation with nearly 99% of monitoring area safe for workers and 50% for individual public. The inclusion of new practices (CTM) and the deposit of radioactive waste coming from other facilities alter this picture dramatically, increased the dose rates. (author)

  6. Wood-inhabiting beetles in low stumps, high stumps and logs on boreal clear-cuts: implications for dead wood management.

    Directory of Open Access Journals (Sweden)

    Jon Andersson

    Full Text Available The increasing demand for biofuels from logging residues require serious attention on the importance of dead wood substrates on clear-cuts for the many forestry-intolerant saproxylic (wood-inhabiting species. In particular, the emerging harvest of low stumps motivates further study of these substrates. On ten clear-cuts we compared the species richness, abundance and species composition of saproxylic beetles hatching from four to nine year old low stumps, high stumps and logs of Norway spruce. By using emergence traps we collected a total of 2,670 saproxylic beetles among 195 species during the summers of 2006, 2007 and 2009. We found that the species assemblages differed significantly between high stumps and logs all three years. The species assemblages of low stumps, on the other hand, were intermediate to those found in logs and high stumps. There were also significant difference in species richness between the three examined years, and we found significant effect of substrate type on richness of predators and fungivores. As shown in previous studies of low stumps on clear-cuts they can sustain large numbers of different saproxylic beetles, including red-listed species. Our study does, in addition to this fact, highlight a possible problem in creating just one type of substrate as a tool for conservation in forestry. Species assemblages in high stumps did not differ significantly from those found in low stumps. Instead logs, which constitute a scarcer substrate type on clear-cuts, provided habitat for a more distinct assemblage of saproxylic species than high stumps. It can therefore be questioned whether high stumps are an optimal tool for nature conservation in clear-cutting forestry. Our results also indicate that low stumps constitute an equally important substrate as high stumps and logs, and we therefore suggest that stump harvesting is done after carefully evaluating measures to provide habitat for saproxylic organisms.

    The increasing demand for forest-derived bio-fuel may decrease the amount of dead wood and hence also the amount of available substrate for saproxylic ( = dead-wood dependent) organisms. Cut stumps constitute a large portion of dead wood in managed boreal forests. The lichen flora of such stumps has received little interest. Therefore, we investigated which lichens that occur on stumps in young (4-19 years), managed forests and analyzed how species richness and occurrence of individual species were related to stump and stand characteristics. We performed lichen inventories of 576 Norway spruce stumps in 48 forest stands in two study areas in Central Sweden, recording in total 77 lichen species. Of these, 14 were obligately lignicolous, while the remaining were generalists that also grow on bark, soil or rocks. We tested the effect of characteristics reflecting successional stage, microclimate, substrate patch size, and the species pool in the surrounding area on (1) total lichen species richness, (2) species richness of obligately lignicolous lichens and (3) the occurrence of four obligately lignicolous lichen species. The most important variables were stump age, with more species on old stumps, and study area, with similar total species richness but differences in occupancy for individual species. Responses for total lichen species richness and species richness of obligately lignicolous lichens were overall similar, indicating similar ecological requirements of these two groups. Our results indicate that species richness measurements serve as poor proxies for the responses of individual, obligately lignicolous lichen species.

    Full Text Available Depression is common, especially in women of child-bearing age; prevalence estimates for this group range from 8% to 12%, and there is robust evidence that maternal depression is associated with mental health problems in offspring. Suicidal behaviour is a growing concern amongst young people and those exposed to maternal depression are likely to be especially at high risk. The aim of this study was to utilise a large, prospective population cohort to examine the relationship between depression symptom trajectories in mothers over the first eleven years of their child's life and subsequent adolescent suicidal ideation. An additional aim was to test if associations were explained by maternal suicide attempt and offspring depressive disorder. Data were utilised from a population-based birth cohort: the Avon Longitudinal Study of Parents and Children. Maternal depression symptoms were assessed repeatedly from pregnancy to child age 11 years. Offspring suicidal ideation was assessed at age 16 years. Using multiple imputation, data for 10,559 families were analysed. Using latent class growth analysis, five distinct classes of maternal depression symptoms were identified (minimal, mild, increasing, sub-threshold, chronic-severe. The prevalence of past-year suicidal ideation at age 16 years was 15% (95% CI: 14-17%. Compared to offspring of mothers with minimal symptoms, the greatest risk of suicidal ideation was found for offspring of mothers with chronic-severe symptoms [OR 3.04 (95% CI 2.19, 4.21], with evidence for smaller increases in risk of suicidal ideation in offspring of mothers with sub-threshold, increasing and mild symptoms. These associations were not fully accounted for by maternal suicide attempt or offspring depression diagnosis. Twenty-six percent of non-depressed offspring of mothers with chronic-severe depression symptoms reported suicidal ideation. Risk for suicidal ideation should be considered in young people whose mothers have a

    Highlights: ► First study on torrefaction of stump for bioenergy application. ► Stump can achieve higher energy densification factors. ► Torrefied stump requires longer grinding time than torrefied wood. - Abstract: A fixed bed reactor has been developed for study of biomass torrefaction, followed by thermogravimetric (TG) analyses. Norway spruce stump was used as feedstock. Two other types of biomass, poplar and fuel chips were also included in the study for comparison. Effects of feedstock types and process parameters such as torrefaction temperature and reaction time on fuel properties of torrefied solid product were investigated. The study has demonstrated that fuel properties, including heating values and grindability of the investigated biomasses were improved by torrefaction. Both torrefaction temperature and reaction time had strong effects on the torrefaction process, but temperature effects are stronger than effects of reaction time. At the same torrefaction temperature, the longer reaction time, the better fuel qualities for the solid product were obtained. However, too long reaction times and/or too higher torrefaction temperatures would decrease the solid product yield. The torrefaction conditions of 300 °C for 35 min resulted in the energy densification factor of 1.219 for the stump, which is higher than that of 1.162 for the poplar wood samples and 1.145 for the fuel chips. It appears that torrefied stump requires much longer time for grinding, while its particle size distribution is only slightly better than the others. In addition, the TG analyses have shown that untreated biomass was more reactive than its torrefaction products. The stump has less hemicelluloses than the two other biomass types. SEM analyses indicated that the wood surface structure was broken and destroyed by torrefaction process

    Background The purpose of this study was to estimate the incidence of fatal and non-fatal Low Speed Vehicle Run Over (LSVRO) events among children aged 0–15 years in Queensland, Australia, at a population level. Methods Fatal and non-fatal LSVRO events that occurred in children resident in Queensland over eleven calendar years (1999-2009) were identified using ICD codes, text description, word searches and medical notes clarification, obtained from five health related data bases across the continuum of care (pre-hospital to fatality). Data were manually linked. Population data provided by the Australian Bureau of Statistics were used to calculate crude incidence rates for fatal and non-fatal LSVRO events. Results There were 1611 LSVROs between 1999–2009 (IR = 16.87/100,000/annum). Incidence of non-fatal events (IR = 16.60/100,000/annum) was 61.5 times higher than fatal events (IR = 0.27/100,000/annum). LSVRO events were more common in boys (IR = 20.97/100,000/annum) than girls (IR = 12.55/100,000/annum), and among younger children aged 0–4 years (IR = 21.45/100000/annum; 39% or all events) than older children (5–9 years: IR = 16.47/100,000/annum; 10–15 years IR = 13.59/100,000/annum). A total of 896 (56.8%) children were admitted to hospital for 24 hours of more following an LSVRO event (IR = 9.38/100,000/annum). Total LSVROs increased from 1999 (IR = 14.79/100,000) to 2009 (IR = 18.56/100,000), but not significantly. Over the 11 year period, there was a slight (non –significant) increase in fatalities (IR = 0.37-0.42/100,000/annum); a significant decrease in admissions (IR = 12.39–5.36/100,000/annum), and significant increase in non-admissions (IR = 2.02-12.77/100,000/annum). Trends over time differed by age, gender and severity. Conclusion This is the most comprehensive, population-based epidemiological study on fatal and non-fatal LSVRO events to date. Results from this study indicate

    Full Text Available We report a case of tinea corporis on amputated leg stump caused by Trichophyton rubrum. The patient, a 54-year-old male, experienced a serious traffic accident, resulted his right leg amputated 3 years ago. Since then prosthesis was fitted and protective equipment of silicone stocking was worn for the stump. He consulted with circular, patchy and scaly erythemas with itching on his right below knee amputation stump for 2 months. The diagnoses of tinea corporis on the stump was made based on a positive KOH direct microscopic examination, morphologic characteristics and sequencing of the internal transcribed spacers (ITS 1 and 4, confirmed that the isolate from the scales was T. rubrum. The patient was cured with oral terbinafine and topical naftifine-ketaconazole cream following 2% ketaconazole shampoo wash for 3 weeks. Long times using prosthesis together with protective equipment of silicone stocking, leading to the local environment of airtight and humid within the prosthesis favors T. rubrum infection of the stump could be considered as the precipitating factors.

A 36-year-old Japanese man with osteogenesis imperfecta type I who had frequently experienced painful fragility fractures consulted our clinic because of chronic back pain. The patient had multiple morphometric vertebral fractures and a low bone mineral density (BMD at the lumbar spine. The patient was treated with cyclical etidronate 200 mg, for 2 weeks every 3 months, plus alfacalcidol 1 µg daily, for 2 years; and alendronate 5 mg daily or 35 mg weekly, plus alfacalcidol 1 µg daily for 9 years. After 11 years of treatment, BMD at the lumbar spine increased by 6.4%, following a 20.3% reduction in serum alkaline phosphatase. Serum calcium, phosphorus, and intact parathyroid hormone levels remained within the normal ranges. Three clinical fractures occurred at two ribs and the metacarpus, and two morphometric vertebral fractures occurred at the thoracic spine during the 11-year treatment period, but the patient experienced no adverse effects.

    A pilot trial of telemedicine in primary care began in the village of Letham in 1998. The service provided conventional consultations with the district nurse, plus teleconsultations with a general practitioner (GP) at the health centre in Forfar, a few km away. In the first year, the videoconferencing link was used by 14 patients, all aged over 65 years. The telemedicine service was judged to be successful and subsequently expanded to patients of any age. It was used for a wide range of health matters, including postnatal care, mental health problems, physical ailments, receiving test results and discussions with the doctor. During the 11-year study period, a total of 646 teleconsultations were conducted, a median rate of 65 per year. A qualitative evaluation of the service was conducted in 1999. Although the GPs involved expressed some reservations about the limited video quality, all three user groups were positive about the service. Nonetheless, the telemedicine service was not adopted as a routine method of health-care delivery by the NHS. To enable any telemedicine application to move from the pilot trial stage to routine service requires several things to happen at an organisational and contractual level. Ultimately an organizational decision about adoption is required, followed by appropriate mechanisms to enable diffusion.

    The Edwards Lifesciences Prima Plus stentless valve (ELSV) is a bioprosthesis manufactured from a porcine aortic root. The study aim was to evaluate late clinical outcomes after aortic valve replacement (AVR) with ELSV implanted as a miniroot in patients with aortic valve disease. Between 1993 and 2004, 318 patients (232 males, 86 females; mean age 69 +/- 9 years; range: 37-83 years) underwent AVR with the ELSV. Preoperatively, 102 patients (32%), 162 (51%) and 54 (17%) were in NYHA classes I/II, III and IV, respectively. Aortic stenosis, aortic regurgitation and combined lesions were present in 124 patients (39%), 114 (36%) and 41 (13%), respectively. Twenty patients (6%) were referred for an acute aortic dissection, 20 (6%) for an aortic root aneurysm, and 139 (44%) had an associated aneurysmal dilatation of the ascending aorta. The ascending aorta was replaced in 159 patients (50%); aortic arch replacement was required in 10 (3%). Coronary artery bypass graft was performed in 86 patients (27%). The follow up was based on clinical data. Operative mortality was 5% (n = 17). There were 49 late deaths (5.2%/pt-yr). Valve-related mortality occurred in 10 patients (1%/pt-yr). Actuarial survival at five and 10 years was 78% and 33%, respectively. Actuarial freedom from valve reoperation and structural valve deterioration at 10 years were 100% and 64%. Actuarial freedom from embolic events and endocarditis at 10 years were 84% and 81%, respectively. The ELSV, when implanted as a miniroot, provided good early and long-term results in terms of survival and freedom from major complications.

    Tillage methods and crop rotation are probably the two most important cropping factors affecting weed communities, particularly when herbicide use is restricted. This study examined weed dynamics following eleven years of different tillage and crop rotation treatments. The aboveground grass weed...... flora was recorded each year and the content and vertical location of individual weed seeds within the plough layer (0–20 cm) were determined after 11 years of continuous mouldboard ploughing (P), pre-sowing tine cultivation to 8–10 cm soil depth (H8-10) and direct drilling (D). The content of weed...... seeds, especially grass weeds, was determined for three distinct soil layers (0–5, 5–10 and 10–20 cm), reflecting the cultivation depths of the tillage treatments. The annual grass weeds, Apera spica-venti and Vulpia myuros, were promoted by non-inversion tillage and in the case of V. myuros also...

    Full Text Available Introduction: The integrated counseling and testing centre (ICTC has proved to be an essential human immunodeficiency virus (HIV infection prevention intervention, especially in nations where poverty, social inequality, and weak health infrastructure exist. Objectives : The study was conducted to (i assess the performance of ICTC in a referral hospital over a period of 11 years (ii understand the regional risk determinants of HIV-positive clients. Materials and Methods : In this record based hospital study, data from January 2000 to December 2010 of all ICTC attendees and HIV-positive clients (excluding pregnant women; surveillance in this group is being conducted routinely was collected by reviewing the records, compiled, and analyzed. Results : A total of 19,234 clients were counseled, of which 17,411 were tested and 970 were detected positive for HIV. The HIV seropositivity amongst the total tested clients was 5.57%. The intake of clients attending ICTC consistently increased from 781 clients in 2000 to 5574 clients in 2010. Amongst the total 970 HIV positives the ratio between male and female positives was 3:2 (m = 584; f = 386. Of these, 42.1% were in the age group of 25-44 years and children (<15 years accounted for 7.8%. The heterosexual route of transmission was documented in 77.4%. In 13.6% (n = 132 HIV-positive clients, the route of transmission was not identified. The provider initiated client visits increased significantly from 4.85% in 2006 to 82.05% in 2010 than the direct walk-in clients (P < 0.0000001. However, the HIV-positive clients were three times more in the direct walk-in clients than in the provider initiated clients (P < 0. 0000001. Conclusion : Increased utilization of ICTC reflects the overall attitudinal changes in behavior and heterosexual high risk behavior continues to be the major route of HIV transmission.

    It is difficult to predict whether a particular attack of neuromyelitis optica spectrum disorder (NMOSD) will affect the optic nerve [optic neuritis (ON): unilateral or bilateral], spinal cord (myelitis), brain or brainstem, or a combination of the above. We report an interesting case of recurrent ON of the same eye for a total of 11 episodes in a Chinese woman. Over a period of 22 years, the attacks only involved the left eye, and never the right eye and also no myelitis. For a prolonged duration, she was diagnosed as recurrent idiopathic ON. Only until she was tested positive for aquaporin 4 antibody that her diagnosis was revised to NMOSD. Optical coherence tomography revealed thinning of the retinal nerve fibre layer (RNFL) for the affected left eye, while the RNFL thickness was within normal range for the unaffected right eye. The disability accrual in NMOSD is generally considered to be attack-related - without a clinical attack of ON, there shall be no visual impairment, and no significant subclinical thinning of RNFL. Our case is in agreement with this notion. This is in contrast to multiple sclerosis where subclinical RNFL thinning does occur. This case highlights the importance of revisiting and questioning a diagnosis of recurrent idiopathic ON particularly when new diagnostic tools are available. Copyright © 2016 Elsevier B.V.

    Purpose: This study was designed to evaluate retrospectively the safety and efficacy of the percutaneous management of duodenal stump leakage with a Foley catheter after subtotal gastrectomy. Methods: Ten consecutive patients (M:F = 9:1, median age: 64 years) were included in this retrospective study. The duodenal stump leakages were diagnosed in all the patients within a median of 10 days (range, 6–20). At first, the patients underwent percutaneous drainage on the day of or the day after confirmation of the presence of duodenal stump leakage, and then the Foley catheters were replaced at a median of 9 days (range, 6–38) after the percutaneous drainage. Results: Foley catheters were placed successfully in the duodenal lumen of all the patients under a fluoroscopic guide. No complication was observed during and after the procedures in all the patients. All of the patients started a regular diet 1 day after the Foley catheter placement. The patients were discharged at a median of 7 days (range, 5–14) after the Foley catheter placement. The catheters were removed in an outpatient clinic 10–58 days (median, 28) after the Foley catheter placement. Conclusions: Fluoroscopy-guided percutaneous Foley catheter placement may be a safe and effective treatment option for postoperative duodenal stump leakage and may allow for shorter hospital stays, earlier oral intake, and more effective control of leakage sites

    Full Text Available Background. In 2005, Nigeria changed its policy on prevention of malaria in pregnancy to intermittent preventive treatment with sulphadoxine-pyrimethamine (IPTp-SP. Indicators of impact of effective prevention and control of malaria on pregnancy (MIP are low birth weight (LBW and maternal anaemia by parity. This study determined the prevalence of LBW for different gravidity groups during periods of pre- and postpolicy change to IPTp-SP. Methods. Eleven-year data were abstracted from the delivery registers of two hospitals. Study outcomes calculated for both pre- (2000–2004 and post-IPTp-SP-policy (2005–2010 years were prevalence of LBW for different gravidity groups and risk of LBW in primigravidae compared to multigravidae. Results. Out of the 11,496 singleton deliveries recorded within the 11-year period, the prevalence of LBW was significantly higher in primigravidae than in multigravidae for both prepolicy (6.3% versus 4% and postpolicy (8.6% versus 5.1% years. The risk of LBW in primigravidae compared to multigravidae increased from 1.62 (1.17–2.23 in the prepolicy years to 1.74 (1.436–2.13 during the postpolicy years. Conclusion. The study demonstrated that both the prevalence and risk of LBW remained significantly higher in primigravidae even after the change in policy to IPTp-SP.

    Stump removal is becoming increasingly important in as demand for renewable energy is increasing. Nutrient concentrations in stumps are applied when evaluating the environmental effect of stump removal on acidification and nutrient balances in forest soil. The objectives of this study was to evaluate concentrations of nutrients in stumps in Sweden, Finland and Denmark, and to evaluate how nutrient concentrations vary with site characteristics, stand age and deposition level. Concentrations of N, P, Ca, K, Mg and Na in spruce, pine and birch stumps were assessed in eight sites across Scandinavia. The results of this study indicate that the concentration of nutrients are higher in birch stumps compared with spruce and pine. In Sweden and Finland, the nutrient concentrations were generally higher in the southern sites compared with northern sites in the country, except for P. Nutrient concentrations were significantly higher in the bark of the stump and the roots compared to the wood for all nutrients. Furthermore nutrients concentration increased significantly with decreasing root diameter. In Jaedraaas, Sweden, nutrient concentration of N, K, Mg and P in pine decreased with age of the stump harvested tree, for stumps < 65 years. This relation was not evident for other age spans or sites. Further studies are needed to provide a broader picture of how the nutrient concentrations vary with site characteristics, stand age and forestry management to get a better foundation when setting up recommendations for stump removal

    Depression is common, especially in women of child-bearing age; prevalence estimates for this group range from 8% to 12%, and there is robust evidence that maternal depression is associated with mental health problems in offspring. Suicidal behaviour is a growing concern amongst young people and those exposed to maternal depression are likely to be especially at high risk. The aim of this study was to utilise a large, prospective population cohort to examine the relationship between depression symptom trajectories in mothers over the first eleven years of their child’s life and subsequent adolescent suicidal ideation. An additional aim was to test if associations were explained by maternal suicide attempt and offspring depressive disorder. Data were utilised from a population-based birth cohort: the Avon Longitudinal Study of Parents and Children. Maternal depression symptoms were assessed repeatedly from pregnancy to child age 11 years. Offspring suicidal ideation was assessed at age 16 years. Using multiple imputation, data for 10,559 families were analysed. Using latent class growth analysis, five distinct classes of maternal depression symptoms were identified (minimal, mild, increasing, sub-threshold, chronic-severe). The prevalence of past-year suicidal ideation at age 16 years was 15% (95% CI: 14-17%). Compared to offspring of mothers with minimal symptoms, the greatest risk of suicidal ideation was found for offspring of mothers with chronic-severe symptoms [OR 3.04 (95% CI 2.19, 4.21)], with evidence for smaller increases in risk of suicidal ideation in offspring of mothers with sub-threshold, increasing and mild symptoms. These associations were not fully accounted for by maternal suicide attempt or offspring depression diagnosis. Twenty-six percent of non-depressed offspring of mothers with chronic-severe depression symptoms reported suicidal ideation. Risk for suicidal ideation should be considered in young people whose mothers have a history of

    Presents a historical review of the utilization of stump- and rot-wood in Finland, based on Finnish literature from the mid 19th century until to-day. Pine stumps were used for tar production to a small extent during the 19th century, and on a much larger scale during the two World Wars. Other industrial uses of stumpwood have hitherto been of minor importance, but stumps are now beginning to be used in the pulp industry. The largest quantity of stumpwood used has always been that taken by the rural population for fuel; it amounted to >200 000 m/sup 3/ solid measure in the 1930's, and was still >100 000 m/sup 3/ in the 1960's.

    Full Text Available The current annual increment (CAIdbh and the mean annual increment (MAIdbh both for the diameter at breast height (1.3 m were investigated to compare the differences between coppice and stump-planted teak in Mae Moh Plantation. Forty-eight sample cores were collected from a 9 yr-old teak plantation using an increment borer; annual increments were analyzed using dendrochronological techniques. The results indicated that there was no significant (p > 0.05 difference in the average diameter at breast height (DBH between the coppice and stump-planted teak, whereas the total height of stump planting was significantly greater than that of coppice teak. The CAIdbh of coppice teak was in the range 0.316–2.371 cm and continuously decreased throughout the 9 yr period. The CAIdbh of stump planting was in the range 0.162–1.982 cm and continuously increased from the beginning of growth for 5 yr followed by a decline thereafter for 4 yr. The CAIdbh of coppice showed rapid growth in the years 1–4 and was greater than for the stump-planted teak even in years 5–8 after planting; however, the growth of the stump-planted teak in the ninth year was higher than for the coppice. The MAIdbh values of coppice and stump-planted teak were not significantly (p > 0.05 different. The results showed that CAIdbh at age 5 yr can be used as a silvicultural guide to increase the yield of teak coppice.

    Full Text Available Studies of secondary aerosol-particle formation depend on identifying days in which new particle formation occurs and, by comparing them to days with no signs of particle formation, identifying the conditions favourable for formation. Continuous aerosol size distribution data has been collected at the SMEAR II station in a boreal forest in Hyytiälä, Finland, since 1996, making it the longest time series of aerosol size distributions available worldwide. In previous studies, the data have been classified as particle-formation event, nonevent, and undefined days, with almost 40% of the dataset classified as undefined. In the present study, eleven years (1996–2006 of undefined days (1630 days were reanalyzed and subdivided into three new classes: failed events (37% of all previously undefined days, ultrafine-mode concentration peaks (34%, and pollution-related concentration peaks (19%. Unclassified days (10% comprised the rest of the previously undefined days. The failed events were further subdivided into tail events (21%, where a tail of a formation event presumed to be advected to Hyytiälä from elsewhere, and quasi events (16% where new particles appeared at sizes 3–10 nm, but showed unclear growth, the mode persisted for less than an hour, or both. The ultrafine concentration peaks days were further subdivided into nucleation-mode peaks (24% and Aitken-mode peaks (10%, depending on the size range where the particles occurred. The mean annual distribution of the failed events has a maximum during summer, whereas the two peak classes have maxima during winter. The summer minimum previously found in the seasonal distribution of event days partially offsets a summer maximum in failed-event days. Daily-mean relative humidity and condensation sink values are useful in discriminating the new classes from each other. Specifically, event days had low values of relative humidity and condensation sink relative to nonevent days. Failed-event days

    Between 1986 and 1990, a series of thinnings were made in previously unthinned first rotation stands on former arable land located in the southern half of Sweden. The aim was to evaluate the effects of season and urea treatment on the frequency of infection of stumps of Norway spruce (Picea abies (L.) Karst.) by the root-rot fungus Heterobasidion annosum (Fr.) Bref. Untreated stumps, resulting from 60 thinnings (22-100 stumps each, altogether ca 3000 stumps) made at different times of year, were investigated 3-24 months after cutting to determine whether they were infected with H. annosum. On average only 2% of the stumps from thinnings made in November-February were infected, whereas the incidence of infection among stumps thinned in June-July was 34%. Two methods of treating stumps with urea to prevent stump infection by H. annosum after thinning were evaluated in terms of effectiveness. The freshly cut stumps were treated with a 20% urea solution, transformed to a gel by adding 0.2% carboxymethyl cellulose, or with a 30% urea solution. On average, the reduction in infection rate obtained was 62% with the first method and 85% with the latter. In a separate study involving a concentration series of urea, there was a considerable drop in protection efficiency, from 89% to 58%, when the concentration was decreased from 30% to 15%. 38 refs, 3 figs, 1 tab

    Eleven patients with T1 and small T2 breast cancer were treated by a combination of quadrantectomy, axillary dissection and radiotherapy. The mean age of the patients was 44.6 years. Mean follow-up period was 7.1 months. Six patients had clinical stage I, and five patients had clinical stage II. Four patients had involvement of axillary content (36.3%) on histological examination. There were eight scirrhous carcinomas and three papillotubular carcinomas. The incidence of local and distant recurrence was none in our group. The multifocality of breast cancer based on pathologic studies had been shown. On the basis of these findings we concluded that the patients undergoing breast conservation should be subjected to postoperative radiotherapy. Psychological morbidity was compared in 10 patients treated by breast conservation and 23 patients treated by mastectomy. There were no statistically significant differences between two groups in the estimation of adjustment disorder, depression, anxiety and stress. The patients in breast conservation group had a significant excess or nervousness and the patients of the mastectomy group had an anger. (author)

    Resin-storing plant species such as conifer trees can release substantial amounts of volatile organic compounds (VOCs) into the atmosphere under stress circumstances that cause resin flow. Wounding can be induced by animals, pathogens, wind or direct mechanical damage e.g. during harvesting. In atmospheric modelling of biogenic VOCs, actively growing vegetation has been mostly considered as the source of emissions. Root systems and stumps of resin-storing conifer trees could constitute a significant store of resin after tree cutting. Therefore, we assessed the VOC emission rates from the cut surface of Scots pine stumps and estimated the average emission rates for an area with a density of 2000 stumps per ha. The experiment was conducted with trees of one Estonian and three Finnish Scots pine provenances covering a 1200 km gradient at a common garden established in central Finland in 1991. VOC emissions were dominated by monoterpenes and less than 0.1% of the total emission was sesquiterpenes. α-Pinene (7-92% of the total emissions) and 3-carene (0-76% of the total emissions) were the dominant monoterpenes. Proportions of α-pinene and camphene were significantly lower and proportions of 3-carene, sabinene, γ-terpinene and terpinolene higher in the southernmost Saaremaa provenance compared to the other provenances. Total terpene emission rates (standardised to +20 °C) from stumps varied from 27 to 1582 mg h-1 m-2 when measured within 2-3 h after tree cutting. Emission rates decreased rapidly to between 2 and 79 mg h-1 m-2 at 50 days after cutting. The estimated daily terpene emission rates on a hectare basis from freshly cut stumps at a cut tree density of 2000 per ha varied depending on provenance. Estimated emission ranges were 100-710 g ha-1 d-1 and 137-970 g ha-1 d-1 in 40 and in 60 year-old forest stands, respectively. Our result suggests that emission directly from stump surfaces could be a significant source of monoterpene emissions for a few weeks after

    The narrow-line Seyfert 1 galaxy (NLS1) Mrk 335 has been continuously monitored with Swift since May 2007 when it fell into a long-lasting, X-ray low-flux interval. Results from the nearly 11 years of monitoring are presented here. Structure functions are used to measure the UV-optical and X-ray power spectra. The X-ray structure function measured between 10 - 100 days is consistent with the flat, low-frequency part of the power spectrum measured previously in Mrk 335. The UV-optical structure functions of Mrk 335 are comparable with those of other Seyfert 1 galaxies and of Mrk 335 itself when it was in a normal bright state. There is no indication that the current X-ray low-flux state is attributed to changes in the accretion disc structure of Mrk 335. The characteristic timescales measured in the structure functions can be attributed to thermal (for the UV) and dynamic (for the optical) timescales in a standard accretion disc. The high-quality UVW2 (˜1800 Å in the source frame) structure function appears to have two breaks and two different slopes between 10 - 160 days. Correlations between the X-ray and other bands are not highly significant when considering the entire 11-year light curves, but more significant behaviour is present when considering segments of the light curves. A correlation between the X-ray and UVW2 in 2014 (Year-8) may be predominately caused by an giant X-ray flare that was interpreted as jet-like emission. In 2008 (Year-2), possible lags between the UVW2 emission and other UV-optical waveband may be consistent with reprocessing of X-ray or UV emission in the accretion disc.

    Purpose: This retrospective review was conducted to determine if delay in the start of radiotherapy after conservative breast surgery had any detrimental effect on local recurrence or disease-free survival in node-negative breast cancer patients. Methods and Materials: A total of 568 patients with T1 and T2, N0 breast cancer were treated with breast-conserving surgery and breast irradiation, without adjuvant systemic therapy, between January 1, 1985 and December 31, 1992 at the London Regional Cancer Centre. The time intervals from definitive breast surgery to breast irradiation used for analysis were 0 to 8 weeks (201 patients), greater than 8 to 12 weeks (235 patients), greater than 12 to 16 weeks (91 patients), and greater than 16 weeks (41 patients). Kaplan-Meier estimates of time to local-recurrence and disease-free survival rates were calculated. Results: Median follow-up was 11.2 years. Patients in all 4 time intervals were similar in terms of age and pathologic features. No statistically significant difference was seen between the 4 groups in local recurrence or disease-free survival with surgery radiotherapy interval (p = 0.521 and p = 0.222, respectively). The overall local-recurrence rate at 5 and 10 years was 4.6% and 11.3%, respectively. The overall disease-free survival at 5 and 10 years was 79.6% and 67.0%, respectively. Conclusion: This retrospective study suggests that delay in the start of breast irradiation of up to 16 weeks from definitive surgery does not increase the risk of recurrence in node-negative breast cancer patients. The certainty of these results is limited by the retrospective nature of this analysis

In this study, we present our 11-year experience in the management and clinical outcome of 888 chest trauma cases as a result of blunt and penetrating injuries in our university hospital in Damascus, Syria. Methods We reviewed files of 888 consequent cases of chest trauma between January 2000 and January 2011. The mean age of our patients was 31 ± 17 years mostly males with blunt injuries. Patients were evaluated and compared according to age, gender, etiology of trauma, thoracic and extra-thoracic injuries, complications, and mortality. Results The leading cause of the trauma was violence (41% followed by traffic accidents (33%. Pneumothorax (51%, Hemothorax (38%, rib fractures (34%, and lung contusion (15% were the most common types of injury. Associated injuries were documented in 36% of patients (extremities 19%, abdomen 13%, head 8%. A minority of the patients required thoracotomy (5.7%, and tube thoracostomy (56% was sufficient to manage the majority of cases. Mean hospital LOS was 4.5 ± 4.6 days. The overall mortoality rate was 1.8%, and morbidity (n = 78, 8.7%. Conclusions New traffic laws (including seat belt enforcement reduced incidence and severity of chest trauma in Syria. Violence was the most common cause of chest trauma rather than road traffic accidents in this series, this necessitates epidemiologic or multi-institutional studies to know to which degree violence contributes to chest trauma in Syria. The number of fractured ribs can be used as simple indicator of the severity of trauma. And we believe that significant neurotrauma, traffic accidents, hemodynamic status and GCS upon arrival, ICU admission, ventilator use, and complication of therapy are predictors of dismal prognosis.

    Parathyroid venous sampling (PAVS) is usually reserved for patients with persistent or recurrent hyperparathyroidism after parathyroidectomy with inconclusive noninvasive imaging studies. A retrospective study was performed to evaluate the diagnostic efficacy of super-selective PAVS (SSVS) in patients needing revision neck surgery with inconclusive imaging. Patients undergoing PAVS between 2005 and 2016 due to persistent or recurrent hyperparathyroidism following surgery were reviewed. PAVS was performed in all patients using super-selective technique. Single-value measurements within central neck veins performed as part of super-selective PAVS were used to simulate selective venous sampling (SVS) and allow for comparison to data, which might be obtained in a non-super-selective approach. 32 patients (mean age 51 ± 15 years; 8 men and 24 women) met inclusion and exclusion criteria. The sensitivity and positive predictive value (PPV) of SSVS for localizing the source of elevated PTH to a limited area in the neck or chest was 96 and 84%, respectively. Simulated SVS, on the other hand, had a sensitivity of 28% and a PPV of 89% based on the predefined gold standard. SSVS had a significantly higher sensitivity compared to simulated SVS (p localizing the source of hyperparathyroidism in patients undergoing revision surgery for hyperparathyroidism in whom noninvasive imaging studies are inconclusive. SSVS data had also markedly higher sensitivity for localizing disease in these patients compared to simulated SVS.

    Up-to-date epidemiological data on depressive disorders is needed to understand changes in population health and health care utilization. This study aims to assess the prevalence of major depressive disorder (MDD) and dysthymia in the Finnish population and possible changes during the past 11 years. In a nationally representative sample of Finns aged 30 and above (BRIF8901), depressive disorders were diagnosed with the Composite International Diagnostic Interview (M-CIDI) in 2000 and 2011. To account for nonresponse, two methods were compared: multiple imputation (MI) utilizing data from the hospital discharge register and from the interview in 2000 and statistical weighting. The MI-corrected 12-month prevalence of MDD was 7.4% (95% CI 5.7-9.0) and of dysthymia was 4.5% (95% CI 3.1-5.9), whereas the corresponding figures using weights were 5.4% (95% CI 4.7-6.1) for MDD and 2.0% (95% CI 1.6-2.4) for dysthymia. Women (OR 2.33, 95% CI 1.6-3.4) and unmarried people (OR 1.54, 95% CI 1.2-2.0) had a higher risk of depressive disorders. There was a significant increase in the prevalence of depressive disorders during the follow-up period from 7.3% in 2000 to 9.6% in 2011. Prevalences were two percentage points higher, on average, when using MI compared to weighting. Hospital treatments for depressive disorders and other mental disorders were strongly associated with nonparticipation. The CIDI response rate dropped from 75% in 2000 to 57% in 2011, but this was accounted for by MI and weighting. Depressive disorders are a growing public health concern in Finland. Non-participation of persons with severe mental disorders may bias the prevalence estimates of mental disorders in population-based studies. Copyright © 2014 Elsevier B.V. All rights reserved.

    Provision of constant and safe blood has been a public health challenge in Sub-Saharan Africa with high prevalence of transfusion-transmissible infections (TTIs). This study was aimed at determining the trend and seroprevalence of HBV, HCV, syphilis and HIV across the years within study among prospective blood donors at blood bank in University of Calabar Teaching Hospital (UCTH), Calabar, Nigeria. A retrospective analysis of blood donor data from January 2005 to December 2016 was conducted in Blood Bank/Donor Clinic of University of Calabar Teaching Hospital, Calabar, Nigeria. Sera samples were screened for hepatitis B surface antigen (HBsAg), antibodies to hepatitis C virus (HCV), human immunodeficiency virus (HIV) 1 and 2 and Treponema pallidum using commercially available immunochromatic based kits. Out of the 24,979 screened prospective donors in the 2005-2016 study period, 3739 (14.96%) were infected with at least one infective agent. The overall prevalence of HBV, HCV, syphilis and HIV were 4.1, 3.6, 3.1 and 4.2%, respectively. During the period of study, the percentage of all transfusion-transmissible infections declined significantly with remarkable decline in HIV. The study showed male dominated donor pool (98.7%) with higher prevalence (4.2%) of transfusion-transmissible infections than in female donors (0.0%). Commercial donors constituted majority (62.0%) of the donors and as well had the highest prevalence of transfusion-transmissible infections. Majority (62.9%) of the donors were repeat donors. HBV, HCV, syphilis and HIV have remained a big threat to safe blood transfusion in Nigeria and Sub-Saharan Africa at large. Strict adherence to selection criteria and algorithm of donor screening are recommended.

    Phenocryst assemblages of lavas from the long-lived Aucanquilcha Volcanic Cluster (AVC) have been probed to assess pressure and temperature conditions of pre-eruptive arc magmas. Andesite to dacite lavas of the AVC erupted throughout an 11-million-year, arc magmatic cycle in the central Andes in northern Chile. Phases targeted for thermobarometry include amphibole, plagioclase, pyroxenes, and Fe-Ti oxides. Overall, crystallization is documented over 1-7.5 kbar (~25 km) of pressure and ~680-1,110 °C of temperature. Pressure estimates range from ~1 to 5 kbar for amphiboles and from ~3 to 7.5 kbar for pyroxenes. Pyroxene temperatures are tightly clustered from ~1,000-1,100 °C, Fe-Ti oxide temperatures range from ~750-1,000 °C, and amphibole temperatures range from ~780-1,050 °C. Although slightly higher, these temperatures correspond well with previously published zircon temperatures ranging from ~670-900 °C. Two different Fe-Ti oxide thermometers (Andersen and Lindsley 1985; Ghiorso and Evans 2008) are compared and agree well. We also compare amphibole and amphibole-plagioclase thermobarometers (Ridolfi et al. 2010; Holland and Blundy 1994; Anderson and Smith 1995), the solutions from which do not agree well. In samples where we employ multiple thermometers, pyroxene temperature estimates are always highest, zircon temperature estimates are lowest, and Fe-Ti oxide and amphibole temperature estimates fall in between. Maximum Fe-Ti oxide and zircon temperatures are observed during the middle stage of AVC activity (~5-3 Ma), a time associated with increased eruption rates. Amphibole temperatures during this time are relatively restricted (~850-1,000 °C). The crystal record presented here offers a time-transgressive view of an evolving, multi-tiered subvolcanic reservoir. Some crystals in AVC lavas are likely to be true phenocrysts, but the diversity of crystallization temperatures and pressures recorded by phases in individual AVC lavas suggests erupting magma

    Eighty-nine patients with previously untreated invasive carcinoma of the cervical stump were seen at Yale-New Haven Hospital from 1953 through 1977. This represented 9.4% of the carcinomas of the cervix seen during this time period. Eighty-five of the 89 patients (95.5%) had ''true'' cancers of the cervical stump diagnosed 2 years or more after subtotal hysterectomy, while 4 of the 89 patients (4.5%) had ''coincident'' cancers diagnosed within 2 years of the subtotal hysterectomy. All cervical cancers were staged by the F.I.G.O. classification. Patient characteristics, methods of management, failure sites and survival of patients with carcinoma of the cervical stump were compared to those patients with carcinoma in the intact uterus. Patients with cervical stump cancers were treated in a similar manner to those with carcinomas of the intact uterus, using a combination of external beam irradiation and intracavitary radium. The stump cancer patients had a similar stage distribution to the patients with cancers of the intact uterus but, on the average, they were older and received less irradiation. The patterns of failure were similar on a stage for stage basis, but the survival and disease-free survival for stump cancer patients were superior to those of the patients with carcinoma of the intact uterus

Nine unilateral BKA were chosen and divided into three groups comprising patients with short, medium, and long stump length. Each of them underwent gait analysis test by Computer Dynography (CDG system to measure the gait parameters. It was found that the ground reaction force is higher in the patients with medium stump length whereas the velocity, step length both for the prosthetic and sound limb and cadence were high in longer stump length. Statistical analysis shows a significant difference (p<0.05 between the gait parameters of BKA with medium and longer stump length. The patients with longer stump length were more efficient than medium and short stump patients as they consumed comparatively lesser energy while walking with self-selected velocity and conventional (Solid ankle cushioned heel SACH foot.

  1. Testing Open-Air Storage of Stumps to Provide Clean Biomass for Energy Production

    Full Text Available When orchards reach the end of the productive cycle, the stumps removal becomes a mandatory operation to allow new soil preparation and to establish new cultivations. The exploitation of the removed stump biomass seems a valuable option, especially in the growing energy market of the biofuels; however, the scarce quality of the material obtained after the extraction compromises its marketability, making this product a costly waste to be disposed. In this regard, the identification of affordable strategies for the extraction and the cleaning of the material will be crucial in order to provide to plantation owners the chance to sell the biomass and offset the extraction costs. Mechanical extraction and cleaning technologies have been already tested on forest stumps, but these systems work on the singular piece and would be inefficient in the conditions of an intensive orchard, where stumps are small and numerous. The objective of this study was to test the possibility to exploit a natural stumps cleaning system through open-air storage. The tested stumps were obtained from two different vineyards, extracted with an innovative stump puller specifically designed for continuous stump removal in intensively-planted orchards. The effects of weathering were evaluated to determine the fuel quality immediately after the extraction and after a storage period of six months with respect to moisture content, ash content, and heating value. Results indicated interesting storage performance, showing also different dynamics depending on the stumps utilized.

    The purpose of this study is to develop a procedure for eradicative brachytherapy that can deliver a curative boost dose to bulky (>4 cm) vaginal stump recurrence of uterine cancer without risk of damaging surrounding organs. We separated risk organs (the rectum and sigmoid) from the target during brachytherapy, with a hyaluronate gel injection into the pararectal space via the percutaneous paraperineal approach under local anesthesia. The rectum anchored to the sacrum by native ligament was expected to shift posteriorly. We encountered a patient with bulky stump recurrence of uterine cancer, approximately 8 cm in maximum diameter. She was complaining of abdominal pain and constipation due to bowel encasement. Following 50 Gy of external beam radiotherapy, we applied a single fraction of brachytherapy under gel separation and delivered 14.5 Gy (50.8 GyE: equivalent dose in 2-Gy fraction calculated with linear quadratic model at α/β=3) to the target. The gel injection procedure was completed in 30 min without complications. A total irradiation dose of 100.8 GyE was delivered to the target and the cumulative minimum dose to the most irradiated rectosigmoidal volume of 2 cc (cumulative D 2cc ) was calculated as 58.5 GyE with gel injection, and was estimated to be 96 GyE without. Over three years, the local stump tumor has completely disappeared, with no complications. Brachytherapy with a pararectal gel injection can be a safe and effective eradicative option for bulky vaginal stump recurrence. (author)

    Carotid stump, the blind remnant of an occluded internal carotid artery, can be a potential source of microemboli, and warrants its exclusion from the vascular lumen to prevent the recurrence of a microembolism. In a 69-year-old male with a symptomatic carotid stump and acute angle between left common carotid artery and aortic arch, a 7-Fr. shuttle sheath was scarcely placed into the left carotid artery but the 7-mm-diameter stent-graft-loading balloon could not be inserted into the 7-Fr. shuttle sheath. With the mounting a stent graft over a 5-mm balloon, the balloon-expandable stent graft was unfolded. The self-expandable stent was placed over the stent graft, and an 8-mm balloon was subsequently expanded. Self-expanding stenting can be useful for troubleshooting in a case of device incompatibility coming from the different calibers of the external and common carotid arteries for the successful exclusion of a symptomatic carotid stump.

    We characterized the sulfur deposition history over the period of industrialization in Japan based on the sulfur isotope ratio (δ(34)S) in tree rings of Japanese cedar (Cryptomeria japonica D. Don) stumps. We analyzed and compared δ(34)S values in the rings from two types of disk samples from 170-year-old stumps that had been cut 5 years earlier (older forest stand) and from 40-year-old living trees (younger forest stand) in order to confirm the validity of using stump disks for δ(34)S analysis. No differences in δ(34)S values by age were found between the sample types, indicating that stump disks can be used for δ(34)S analysis. The δ(34)S profile in tree rings was significantly correlated with anthropogenic SO2 emissions in Japan (r = -0.76, p tree rings serve as a record of anthropogenic sulfur emissions. In addition, the values did not change largely from pre-industrialization to the 1940s (+4.2 to +6.1‰). The values before the 1940s are expected to reflect the background sulfur conditions in Japan and, thus, disks containing rings formed before the 1940s contain information about the natural environmental sulfur, which is useful for biogeochemical studies.

  6. Short-term responses of decomposers and vegetation to stump removal

    Kataja-aho, S.

    2011-07-01

    Stump removal has become a common practice to produce raw material for bioenergy production. It was hypothesized that stump removal is an extensive and more intense disturbance for forest ecosystems (soil decomposer organisms and vegetation) compared to traditional site preparation after clear cutting. Therefore, the effects of stump harvesting on forest soil decomposers, vegetation and nutrient dynamics in undisturbed patches of the forest soil and in exposed mineral soil were compared to the effects of the traditional site preparation method, mounding. Nematodes and enchytraeids were the only decomposer groups that were directly affected (negatively) by the stump removal. Regardless of the treatment, the abundances of most of the decomposer groups were consistently lower in the exposed mineral soil than in the intact forest soil. There was 2-3 times more exposed mineral soil in stump removal sites compared to mounding sites. When this was taken into account, the decomposer community was negatively affected by the stump removal at the forest stand level. However, the greater soil disturbance at the stump harvesting sites enhanced CO{sub 2} production, net nitrogen mineralisation and nitrification. The increased N availability and the changes in microclimate due to the disturbance probably explained the vegetation increase at the stump harvested sites. Planted Norway spruce seedlings grew faster during the first two growing periods at the stump removal sites than at the mounding sites. The seedlings had high and similar ectomycorrhizal colonization rate in both treatments. In the short-term, it is probably not the resources removed in the stumps themselves, but the degree and amount of soil disturbance during the stump harvesting procedure that affects the decomposer community and its function in the clear-felled stands.

    Full Text Available 7-Eleven, a Japanese retailer is very popular and loved in Jakarta. 7-Eleven or commonly abbreviated to Sevel is now reaping a lot of fans because of the concept of 7-Eleven Indonesia, found only in Indonesia. With the rising middle classes in Indonesia, 7-Eleven becomes a luxurious place for hanging-out but affordable. Consequently, it is attracting the interest of investors to make such a kind of convenience store like Sevel, and it is likely the competition in this sector will be increasingly fierce. PT. Modern’s initial plans are to focus onopening stores in Jakarta, targeting densely-populated commercial and office areas, to offer Indonesian workersa convenient place to shop for lunch, snacks, and emergency items. The company’s goal is to focus on opening stores in Jakarta in its first years of operation. Other major cities, such as Bandung, Semarang, and Surabaya offer for future expansion opportunities. The objective of this article is to describe the competitive condition in convenience store industries using Porter’s Five Forces model. Although the competition is fierce andunfavorable industry condition, Sevel is still leading and dominating the convenience store market in Indonesia.

    Full Text Available Bixin Zheng, Li Song, Hui Liu Department of Pain Management, West China Hospital of Sichuan University, Chengdu, China Abstract: The post-amputation (pain syndrome, including stump pain, phantom limb sensation, and phantom limb pain is common but difficult to treat. Refractory stump pain in the syndrome is an extremely challenging and troublesome clinical condition. Patients respond poorly to drugs, nerve blocks, and other effective treatments like spinal cord stimulation and surgery. Pulsed radiofrequency (PRF technique has been shown to be effective in reducing neuropathic pain. This report describes a patient with persistent and refractory upper limb stump pain being successfully relieved with PRF of brachial plexus under ultrasound guidance after a 6-month follow-up period, suggesting that PRF may be considered as an alternative treatment for refractory stump-neuroma pain.

    Full Text Available Background: Coverage of the bronchial stumps (BSs with adjacent tissues can improve healing and reduce bronchial complications in complex thoracic surgery. There is no evidence for the application of human amnion allograft for prevention of air leak from the BS. The comparison of the amniotic membrane (AM and pleural patch for BS healing after lobectomy in dogs was our aim in this study. Materials and Methods: A total of eight males and females 12-24-month-old dogs between 17 and 22 kg body-weight were used in this study in 2010, Isfahan University of Medical Sciences. Animals were separated into two groups: group A (n = 4; amniotic membrane and group P (n = 4; pleural patch according to the BS closure technique performed. After lobectomy of the right middle lobe, the BS was closed, while a small bronchopleural fistula (BPF was created by inserting a catheter via edges of closed stump. Then, it was covered with a piece of AM3 × 3 cm in group A and with a pedicle graft of pleura in group P. Rethoracotomy was performed after 15 days of observation, and the BS was removed for histological examination. Histological healing was classified as complete or incomplete healing. Neoangiogenesis was measured by Von Willebrand expression using immunohistochemistry (IHC. Data were analyzed by SPSS version 15 using Fisher′s exact test, Mann-Whitney test, and T tests. Results: BPF complications were not seen during observation period. There was no significant difference in histological healing between two groups. Similarly, no significant difference was observed between the groups in terms of neoangiogenesis based on IHC examination (P value = 0.69. Conclusion: Human amnion allograft could be as effective as pleural patch for BS wrapping following pulmonary resections.

    To observe clinical efficacy in treating cutaneous deficiency of traumatic shank amputation stump with full-thickness skin graft combined with vacuum sealing drainage. From September 2009 to December 2012, 15 patients with cutaneous deficiency of traumatic shank amputation stump were treated with full-thickness skin graft combined with vacuum sealing drainage. Among patients, there were 11 males and 4 females with an average age of 41.5 (ranged from 25 to 62) years old. Ten cases were caused by traffic accident and 5 cases were caused by heavy object, 9 cases on left and 6 cases on right. Six patients with smashed wound were treated with debridement and amputation, combined with vacuum aspiration in-emergency; 9 patients caused by infection and necrosis were treated with debridement and amputation, combined with vacuum aspiration, and full-thickness skin graft were performed at stage II. The skin defect area of residual limbs ranged from 40 cm x 20 cm to 25 cm x 15 cm. All patients were followed up from 3 months to 1 year. Full-thickness skin graft of residual limbs were survived,and obtained satisfactory walking function with prosthetic. Residual skin increased thicken, wearproof without rupture and pain. Full-thickness skin graft combined with vacuum sealing drainage in treating cutaneous deficiency of traumatic shank amputation stump could reserve the length of residual limbs, increase survival rate of skin graft with less scar of survival skin, get good wearability and it is conducive to prosthetic wear. It is a simple and easy treatment method.

    The authors assessed the outcome in 252 patients with small-cell lung cancer 5 to 11 years after treatment with combination chemotherapy, with or without chest and cranial irradiation, in National Cancer Institute therapeutic trials from 1973 through 1978. Twenty-eight patients (11%) survived free of cancer for 30 months or more. Fourteen patients remain alive without evidence of cancer beyond 5 years, and 7 patients have returned to a lifestyle similar to that before diagnosis. The other 14 patients who were cancer-free at 30 months have developed cancer or died. A few patients with small-cell lung cancer (5.6%) may be cured. Thirty-month, cancer-free survival is insufficient to show a cure. Although late toxicities are troublesome, they do not outweigh the benefits of prolonged survival and potential for cure with modern aggressive therapy in small-cell lung cancer

    This thesis summarises and discusses results from two studies on mechanized stump treatment to control the root rot fungus Heterobasidion annosum (Fr.) Bref. In Sweden, stump treatment is at present carried out with two chemical compounds, urea and disodium octaborate tetrahydrate (DOT), and a biological control agent, Phlebiopsis gigantea (Fr.) Juel. The first study investigated the H. annosum colonization of Norway spruce (Picea abies (L.) Karst) stumps following mechanized thinning and stump treatment with the three control agents mentioned. The stumps were treated in the summer and were compared with untreated stumps, cut in the summer and winter, respectively. Experimental plots were established in 12 first thinning stands of Norway spruce. Six to seven weeks after thinning and treatment, sample discs were collected (N=1246) and examined for presence of H. annosum. Stump treatment with any of the control agents reduced the colonized stump area 6-7 weeks after thinning by 88-98% as compared with untreated stumps cut in the summer. The effects of the different treatments differed neither from each other nor from the effect of winter thinning. The variation between the stands was considerable, but mechanized stump treatment provided as good protection as manual treatment against H. annosum infections. Study II examined the survival of P. gigantea oidiospores in aqueous suspension when exposed to high temperature or pressure, which are potential problems in mechanized application. In the laboratory, temperatures of 20, 30 or 35 deg C did not affect the survival. The spores could withstand 40 deg C for a short period, but died at 60 deg C. Pressure of up to 2 200 kPa for 24 h did not affect P. gigantea spore germination. In the field, temperatures of the working suspension (10{sup 7} spores I{sup -1}) was assessed during practical operations. Spore viability was maintained through the applicator system. As long as the prescriptions are followed up to the time of

    Frölke, Jan Paul M; van de Meent, Henk

    2010-01-01

    Following lower limb amputation, quality of life is highly related to the ability to use a prosthetic limb. The conventional way to attach a prosthetic limb to the body is with a socket. Many patients experience serious discomfort wearing a conventional prosthesis because of pain, instability during walking, pressure sores, bad smell or skin irritation. In addition, sitting is uncomfortable and pelvic and lower back pain due to unstable gait is often seen in these patients. The main disadvantage of the current prosthesis is the attachment of a rigid prosthesis socket to a soft and variable body. The socket must fit tightly for stability during walking but should also be comfortable for sitting. The implantation of an osseointegrated, intramedullary, transcutaneously conducted prosthesis is a new procedure for attaching a limb prosthesis to the human body without the disadvantages of the conventional prosthesis. The intramedullary prosthesis is designed with a rough surface resembling cancellous bone to enable a secure solid integration with the long bone. We treated two patients with this new prosthesis, a 44-year-old man after a transfemoral amputation, and a 32-year-old woman after a lower leg amputation; both amputations were necessary because of trauma. Those two patients are now, more than one year after the operation, showing excellent functional results without infectious complications. We assume that endo-exo prosthesis may be a promising option for selected patients unable to use a conventional prosthesis because of a problematic amputation stump.

    Epidemiological register of Chernobyl child victims was created in 1986 in Scientific Centre for Radiation Medicine. It includes most important, risk groups: evacuated children from Chernobyl's zone; children who were exposed with doses on thyroid gland more than 2 Gy; children who were exposed in utero; children who were born from clean-up workers. The annual clinical observation program includes: physical examination, biochemical and hematological analysis, ultrasound of thyroid gland and abdomen, psychological tests for children, social observation for parents. For coding ICD-9 was used. The observations indicate a deterioration of health status among the children victims of the Chernobyl disaster. The healthy children's number decreased from 31 % in 1987 to 8 % in 1997. The number of the invalids more than 4 times higher in comparison Ukrainian children. The annual prevalence all diseases including incidence, new cases, dramatically increased (from 5890.6 0/00 in 1989 to 9148.3 0/00 in 1997). The annual amount all diseases increased from 27100 0/00 in 1989 to 51971 0/00 in 1997. Most important increasing was in such part as digestive tract (from 5294 0/00 in 1989 to 10782 0/00 in 1997), blood diseases (from 927 0/00 in 1989 to 1471 0/00 in 1997), diseases nervous system (from 2373 0/00 in 1989 to 4152 0/00 in 1997). Relative risk was calculated in comparison with same age Ukrainian children for most important disorders: peptic (6.4), cardiovascular (5.3), nervous system (6.2), immune (5.3). Such diseases as digestion organ diseases, nervous system, skin and cardiovascular diseases are more prevalent among victims with psychological impact. All children victims Chernobyl disaster are at risk for psychosomatic disorders. Psychosomatic health promotion program will minimize significantly population health impact after Chernobyl as for children as for Ukrainian adult people. (authors)

  10. LEP shuts down after eleven years of forefront research

    2000-01-01

    After extended consultation with the appropriate scientific committees, CERN’s Director-General Luciano Maiani announced today that the LEP accelerator had been switched off for the last time. LEP was scheduled to close at the end of September 2000 but tantalising signs of possible new physics led to LEP’s run being extended until 2 November. At the end of this extra period, the four LEP experiments had produced a number of collisions compatible with the production of Higgs particles with a mass of around 115 GeV. These events were also compatible with other known processes. The new data was not sufficiently conclusive to justify running LEP in 2001, which would have inevitable impact on LHC construction and CERN’s scientific programme. The CERN Management decided that the best policy for the Laboratory is to proceed full-speed ahead with the Large Hadron Collider (LHC) project.

    Various forms of cancer are rising all over the world, requiring newer therapy. The quest of anticancer drugs both from natural and synthetic sources is the demand of time. In this study, fourteen extracts of different parts of eleven Bangladeshi medicinal plants which have been traditionally used for the treatment of different types of carcinoma, tumor, leprosy, and diseases associated with cancer were evaluated for their cytotoxicity for the first time. Extraction was conceded using methanol. Phytochemical groups like reducing sugars, tannins, saponins, steroids, gums, flavonoids, and alkaloids were tested using standard chromogenic reagents. Plants were evaluated for cytotoxicity by brine shrimp lethality bioassay using Artemia salina comparing with standard anticancer drug vincristine sulphate. All the extracts showed potent to moderate cytotoxicity ranging from LC50 2 to 115 µg/mL. The highest toxicity was shown by Hygrophila spinosa seeds (LC50 = 2.93 µg/mL) and the lowest by Litsea glutinosa leaves (LC50 = 114.71 µg/mL) in comparison with standard vincristine sulphate (LC50 = 2.04 µg/mL). Among the plants, the plants traditionally used in different cancer and microbial treatments showed highest cytotoxicity. The results support their ethnomedicinal uses and require advanced investigation to elucidate responsible compounds as well as their mode of action.

    Eleven cases of neonatal intracranial hemorrhage were diagnosed and followed up by CT scanning. By CT, hemorrhagic lesions were shown as high density areas in an acute stage and imaged as low density areas after the hemorrhage was absorbed. The time of absorption varies depending upon the site and the severity of hemorrhage. Intraventricular hemorrhage, petechial hemorrhage and subdural hematoma were absorbed rapidly in more than 70% of the exanimed cases, CT scanning 1 - 2 weeks after the onset revealed absorption of hemorrhage. However, the absorption delayed in intracerebral hematoma; CT scan taken after one month showed hemorrhagic lesions remaining in 75% of the cases. In nine cases who survived, following the absorption of the hemorrhagic lesions, cerebral atrophy was observed in 4 cases (44%), ventricular enlargement in 3 cases (33%), and complete recovery in 2 cases (22%). From these results, CT scanning for diagnosis of neonatal intracranial hemorrhage should be done before the hemorrhagic lesion is absorbed (within 7 days of the onset). Follow-up study by CT is important for observing changes and predicting prognosis of intracranial hemorrhage. (Ueda, J.)

    The C5-C6 nerve roots are usually spared from avulsion after brachial plexus injury (BPI) and thus can be used as donors for nerve grafting. To date, there are no appropriate animal models to evaluate spared nerve root stumps. Hence, the aim of this study was to establish and evaluate a rat model with spared nerve root stumps in BPI. In rupture group, the proximal parts of C5-T1 nerve roots were held with the surrounding muscles and the distal parts were pulled by a sudden force after the brachial plexus was fully exposed, and the results were compared with those of sham group. To validate the model, the lengths of C5-T1 spared nerve root stumps were measured and the histologies of the shortest one and the corresponding spinal cord were evaluated. C5 nerve root stump was found to be the shortest. Histology findings demonstrated that the nerve fibers became more irregular and the continuity decreased; numbers and diameters of myelinated axons and thickness of myelin sheaths significantly decreased over time. The survival of motoneurons was reduced, and the death of motoneurons may be related to the apoptotic process. Our model could successfully create BPI model with nerve root stumps by traction, which could simulate injury mechanisms. While other models involve root avulsion or rupturing by distal nerve transection. This model would be suitable for evaluating nerve root stumps and testing new therapeutic strategies for neuroprotection through nerve root stumps in the future. Copyright © 2017.

    Full Text Available The crown of tree is the centre of physiological activity which gives an indication of the potential photosynthetic capacity on a tree. Though, its measurement remains a challenge in forest inventory task. The ability to predict crown diameter from stump diameter provides an effective technique of obtaining its estimate. This helps in detecting the excessive tree felling than actual requirements and wildlife suitability.The main objective of this study was to develop and test crown diameter prediction models for silvicultural management of naturally grown Parkia biglobosa within the University of Agriculture, Makurdi. Nine 100 m x 100 m temporary sample plots were established using simple random sampling method. Crown diameter and stump diameter were measured in all living P. biglobosa trees with stump diameter ≥10.0 cm. Least square method was used to convert the counted stumps into harvested crown dimension. Three linear and three non-linear models using stump diameter as the exploratory variable were developed and evaluated using the adjusted coefficient of determination (Adj.R2, standard error of estimate (SEE, prediction error sum of squares (PRESS and Akaike information criterion (AIC. The crown-stump diameter relationship was best described by the double logarithmic function with .The result showed that Crown diameter estimation was feasible even when the only information available is stump diameter.The resulting equation was tested for validation with independent data obtained from additional plots and was found to be desirable for estimating the crown diameter for Parkia biglobosa in Makurdi, Benue State, Nigeria.

    Full Text Available Heterobasidion spp. root rot causes severe damage to forests throughout the northern temperate zone. In order to prevent Heterobasidion infection in summertime cuttings, stumps can be treated with urea or Phlebiopsis gigantea. In this study, the consumption of stump treatment materials and the quality of stump treatment work were investigated. A total of 46 harvesters were examined in May–November 2016 in Finland. The average stem size of softwood removal and softwood removal per hectare explained the consumption of stump treatment material. The quality of stump treatment work was good in the study. The best coverage was achieved with the stumps of 20–39 cm diameter at stump height (d0. It can be recommended that the harvester operator self-monitors and actively controls his/her treatment result in cutting work and sets the stump treatment equipment in a harvester if needed. The results also suggested that when cutting mostly small- and medium-diameter (d0 ≤ 39 cm conifers, the stump treatment guide bars with relatively few (<18 open holes are used, and at the harvesting sites of large-diameter trees, the guide bars with a relatively great (>27 number of open holes are applied.

    This is the first update of a Cochrane review published in Issue 5, 2010 on transcutaneous electrical nerve stimulation (TENS) for phantom pain and stump pain following amputation in adults. Pain may present in a body part that has been amputated (phantom pain) or at the site of amputation (stump pain), or both. Phantom pain and stump pain are complex and multidimensional and the underlying pathophysiology remains unclear. The condition remains a severe burden for those who are affected by it. The mainstay treatments are predominately pharmacological, with increasing acknowledgement of the need for non-drug interventions. TENS has been recommended as a treatment option but there has been no systematic review of available evidence. Hence, the effectiveness of TENS for phantom pain and stump pain is currently unknown. To assess the analgesic effectiveness of TENS for the treatment of phantom pain and stump pain following amputation in adults. For the original version of the review we searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, PsycINFO, AMED, CINAHL, PEDRO and SPORTDiscus (February 2010). For this update, we searched the same databases for relevant randomised controlled trials (RCTs) from 2010 to 25 March 2015. We only included RCTs investigating the use of TENS for the management of phantom pain and stump pain following an amputation in adults. Two review authors independently assessed trial quality and extracted data. We planned that where available and appropriate, data from outcome measures were to be pooled and presented as an overall estimate of the effectiveness of TENS. In the original review there were no RCTs that examined the effectiveness of TENS for the treatment of phantom pain and stump pain in adults. For this update, we did not identify any additional RCTs for inclusion. There were no RCTs to judge the effectiveness of TENS for the management of phantom pain and stump pain.

    In this study, we analysed and compared costs, primary energy use and CO{sub 2} benefits of recovering stumps and small roundwood from thinnings, together with logging residues. Small roundwood, chipped at a terminal or end-user, has a cost comparable to the chip system and a primary energy use comparable to the bundle system used for recovery of logging residues. The small roundwood system with roadside chipping is more expensive. As productivity in the cutting process improves, the small roundwood alternatives become more cost-effective. The stump system has costs in the same range as or lower than the chip and bundle systems. Forestry operations for stump and small roundwood recovery require considerable primary energy, but net recovery per hectare is much greater than for the chip and bundle systems, which means that more fossil fuel can be displaced per hectare of clearcut than with a chip or a bundle system. Stumps and small roundwood from thinnings can become as cost-effective as logging residues in the near future. Furthermore, when stumps and small roundwood from thinnings are also used to replace fossil fuels, the potential CO{sub 2} reduction will be about four times as great as when only logging residues are used with a traditional chip system.

    First, we review a result in our previous paper, of how a ten-dimensional superparticle, taken off-shell, has a hidden eleven-dimensional super Poincare symmetry. Then, we show that the physical sector is defined by three first-class constraints which preserve the full eleven-dimensional symmetry. Applying the same concepts to the eleven-dimensional superparticle, taken off-shell, we discover a hidden twelve-dimensional super Poincare symmetry that governs the theory

    Full Text Available Abstract The present report describes a case where typical findings of traumatic glenohumeral interposition of rotator cuff stumps were surgically confirmed. This condition is a rare complication of shoulder trauma. Generally, it occurs in high-energy trauma, frequently in association with glenohumeral joint dislocation. Radiography demonstrated increased joint space, internal rotation of the humerus and coracoid process fracture. In addition to the mentioned findings, magnetic resonance imaging showed massive rotator cuff tear with interposition of the supraspinatus, infraspinatus and subscapularis stumps within the glenohumeral joint. Surgical treatment was performed confirming the injury and the rotator cuff stumps interposition. It is important that radiologists and orthopedic surgeons become familiar with this entity which, because of its rarity, might be neglected in cases of shoulder trauma.

    Displacement of a portion of the torn anterior cruciate ligament (ACL) into the intercondylar notch can cause a focal fibrotic reaction similar to that seen following ACL reconstruction. This displacement, which can result in locking or limitation of knee extension, is termed stump entrapment and is described in adult MR imaging literature. We present a pictorial essay of the etiology and appearance of stump entrapment on MR imaging of the knee in an older child and adolescents and review the significance of this finding. (orig.)

    Amputation injuries in children occur in motor vehicle, farming and, importantly, lawn mower accidents. Treatment of lawn mower related injuries is complicated by gross wound contamination, avascular tissue, soft tissue defects and exposed bone. Many treatment options exist and often an adequate prosthetic supply is needed for rehabilitation. We report on an 8-year old boy who got under a ride-on lawn mower and sustained a subtotal amputation of his right foot. After initial surgery an amputation was subsequently necessary. For this, it had to be taken into account that the traumatic loss of the talus, calcaneus and parts of the cuboid bone would result in a length shortening of the right leg and so far not injured metatarsal and tarsal bones had to be sacrificed. Thus, we aimed to develop a new operation technique to optimize stump length as well as preserve tarsal bones and the possibility of limb growth. In order to achieve this, we performed a new stump forming operation in which we integrated uninjured tarsal and metatarsal bones. First a Lisfranc's amputation was performed and a metatarsal bone was kept aside. The talus, calcaneus as well as the cuboid bone were either completely or almost completely destroyed and were removed. The remaining cuneiform bones were transfixed by a notched metatarsal bone, thus achieving a tarsal arthrodesis, and the cartilages of the proximal joint surfaces were removed. The cartilage of the cranial and caudal navicular as well as the distal tibial joint surface was also removed and an arthrodesis between the distal tibia and the navicular bone was achieved by crossed Kirschner wires. Finally the cuneiform bones were placed inferior to the navicular bone. Further stump coverage was managed by skin and muscle flaps as well as split skin graft. Our patient was discharged on day 34. A fluent gait without crutches as well as sports activities were possible again as early as 6 1/2 months after the injury. Using our stump forming

King Saud University, Riyadh, Saudi Arabia, from October 2013 to January 2014. Arabbit model was developed and studied tendon retraction and histological changes in the proximal and distal stumps following transection of the Achilles tendon. Over a period of 12 weeks, retraction of the distal tendon stump was minimal (2 - 3 mm). In contrast, retraction of the proximal tendon stump peaked to reach 6 mm at 4 weeks post-injury and plateaued to reach 7 - 8 mm at the 12-week interval. Following complete transection of the Achilles tendon, tendon retraction correlated with the density of myofibroblast expression within the tendon stump. Further research is needed to investigate the pathophysiology of these findings.

    The transition from the last Ice Age to the early Holocene 15'000-10'000 BP represents a close natural analog to the ongoing and predicted rates of anthropogenic climate change. A reduced quality and quantity of high-resolution proxy archives during this period, however, limits our understanding of the magnitude and pace of Late Glacial (LG) environmental variability. Here, we present the world's best preserved, most replicated and oldest forest remains: A total of 253 subfossil pine stumps were recently discovered in Zurich. The combined approach of tree-ring and radiocarbon (14C) measurements results in an absolutely dated Preboreal Swiss tree-ring width chronology and eight floating chronologies. With tree ages ranging between 41 and 506 years, often including pith and bark, and a mean segment length of 163 years, this exceptional find is distributed over nearly 2'000 years between the Allerød and the Preboreal. Together with 200 previously collected LG pines from the greater Zurich region, this study sets a benchmark in terms of sample replication and dating precision for stable more dynamic climatic periods such as the Laacher See eruption, the Older and Younger Dryas. The paleoenvironmental significance would even increase when annually resolved 14C-measurements help fixing a major, Northern Hemispheric gap in the absolutely dated dendro time series during the Younger Dryas. While overcoming this interlude, our results further emphasize the importance of interdisciplinary research on these striking LG climatic shifts to better understand and assess their ecological and environmental impact.

    The investigated northwest German mire site at Totes Moor is densely covered with subfossil pine stumps (Pinus sylvestris L.) from the fen-bog transition. This facilitates the spatio-temporal reconstruction of mire development, which is based on 212 in situ tree stumps in the case study presented here. Six dendrochronologically dated site chronologies together cover 2345 years between 6703 and 3403 BC. The gaps in between are 6 to 550 years long. Additionally, a floating chronology of 309 years, containing 30 trees, was radiocarbon-dated to the beginning of the 7th millennium cal BC. Peat-stratigraphical survey was carried out additionally, and elevations a.s.l. were determined at several locations. Tree dying-off phases, which indicate water level rise at the site, mostly in context of the local fen-bog transition, are evident for ca. 6600-6450, ca. 6350-5750, ca. 5300-4900, ca. 4700-4550, ca. 3900-3850, ca. 3700-3600, ca. 3500-3450 and ca. 3400 BC. The spatial distribution of the dated in situ trees illustrates the phase-wise expansion of raised bog over fen peat at the site. The documented bog expansion pulses likely correspond to climatic wet sifts.

    Duodenal stump insufficiency after surgery for penetrating gastroduodenal ulcer is associated with substantial mortality. "Classical" technique of closing a difficult duodenal stump (Nissen-Bsteh) has, up to now, not been compared with duodenojejunostomy (DJ) in larger patient sets. This also refers to the potential benefit of a gastric and biliary diversion under such conditions. The aim of the present study was to compare classical duodenal closure (CC) with DJ and to evaluate the impact of gastric and biliary diversion on postoperative outcome after surgery for penetrating, high-risk duodenal ulcer in a matched control study. Out of 321 patients, treated for penetrating duodenal ulcer disease, the perioperative outcome of 62 DJ patients was compared with 62 patients undergoing CC matched for age, gender, biliary diversion, and the operating surgeon collective. A total of 70 patients, equally distributed between DJ and CC subsets, received temporary biliary diversion. Overall perioperative mortality was 10.5%. However, DJ significantly reduced the mortality rate (4.8%) associated with penetrating duodenal ulcer compared to CC (16.1%, P management of penetrating duodenal ulcer.

    We report on the utility of the modified Breen method in addition to the Sauve-Kapandji operation for the treatment of instability and pain in the proximal ulnar stump in rheumatoid arthrities (RA) wrist. We treated a total of 15 hands in 12 patients with disturbances due to instability and pain at the proximal ulnar stump. The average follow-up period was 47 months. We evaluated the range of motion, grip strength, radioulnar distance, and the radioulnar distance at the stump using CT during pronation, supination, and neutral positions of the forearm in 11 of the 15 operated hands. We observed that none of the patients showed any signs of pain at the proximal ulnar stump and no scallop sign was observed. In all the cases, the line connecting the center of the radial head to the proximal ulnar stump served as the axis of rotation for the forearm; this was confirmed by the CT images. We concluded that our operative method resulted in stabilization of the proximal ulnar stump and recovery of powerful grip without pain during forearm rotation. (author)

    Eleven-dimensional supergravity can be formulated in superspaces locally of the form X × Y where X is 4D N = 1 conformal superspace and Y is an arbitrary 7-manifold admitting a G 2-structure. The eleven-dimensional 3-form and the stable 3-form on Y define the lowest component of a gauge superfield on X × Y that is chiral as a superfield on X. This chiral field is part of a tensor hierarchy giving rise to a superspace Chern-Simons action and its real field strength defines a lifting of the Hitchin functional on Y to the G 2 superspace X × Y . These terms are those of lowest order in a superspace Noether expansion in seven N = 1 conformal gravitino superfields Ψ. In this paper, we compute the O(Ψ) action to all orders in the remaining fields. The eleven-dimensional origin of the resulting non-linear structures is parameterized by the choice of a complex spinor on Y encoding the off-shell 4D N = 1 subalgebra of the eleven-dimensional super-Poincaré algebra.

    Severe post-operative complications after pancreaticoduodenectomy (PD) are largely due to pancreatic fistula onset. The occlusion of the main pancreatic duct using synthetic glue may prevent these complications. Aim of this study is to describe this technique and to report short- and long-term results as well as the post-operative endocrine and exocrine insufficiency. Two hundred and four patients who underwent PD with occlusion of the main pancreatic duct in a period of 15 years were retrospectively analyzed. Post-operative complications and their management were the main aim of the study with particular focus on pancreatic fistula incidence and its treatment. At 1-year follow-up endocrine and exocrine functions were analyzed. We observed a 54 % pancreatic fistula incidence, most of which (77/204 patients) were a grade A fistula with little change in medical management. Twenty-eight patients developed a grade B fistula while only 2 % of patients (5/204) developed a grade C fistula. Nine patients required re-operation, 5 of whom had a post-operative grade C fistula. Post-operative mortality was 3.4 %. At 1-year follow-up, 31 % of patients developed a post-operative diabetes while exocrine insufficiency was encountered in 88 % of patients. The occlusion of the main pancreatic duct after PD can be considered a relatively safe and easy-to-perform procedure. It should be reserved to selected patients, especially in case of soft pancreatic texture and small pancreatic duct and in elderly patients with comorbidities, in whom pancreatic fistula-related complications could be life threatening.

    Interfacing an amputee's upper-extremity stump nerves to control a robotic hand requires training of the individual and algorithms to process interactions between cortical and peripheral signals. To evaluate for the first time whether EEG-driven analysis of peripheral neural signals as an amputee practices could improve the classification of motor commands. Four thin-film longitudinal intrafascicular electrodes (tf-LIFEs-4) were implanted in the median and ulnar nerves of the stump in the distal upper arm for 4 weeks. Artificial intelligence classifiers were implemented to analyze LIFE signals recorded while the participant tried to perform 3 different hand and finger movements as pictures representing these tasks were randomly presented on a screen. In the final week, the participant was trained to perform the same movements with a robotic hand prosthesis through modulation of tf-LIFE-4 signals. To improve the classification performance, an event-related desynchronization/synchronization (ERD/ERS) procedure was applied to EEG data to identify the exact timing of each motor command. Real-time control of neural (motor) output was achieved by the participant. By focusing electroneurographic (ENG) signal analysis in an EEG-driven time window, movement classification performance improved. After training, the participant regained normal modulation of background rhythms for movement preparation (α/β band desynchronization) in the sensorimotor area contralateral to the missing limb. Moreover, coherence analysis found a restored α band synchronization of Rolandic area with frontal and parietal ipsilateral regions, similar to that observed in the opposite hemisphere for movement of the intact hand. Of note, phantom limb pain (PLP) resolved for several months. Combining information from both cortical (EEG) and stump nerve (ENG) signals improved the classification performance compared with tf-LIFE signals processing alone; training led to cortical reorganization and

    Various fingertip reconstructions have been reported for situations where microsurgical finger replantation is impossible. One method is the digital artery perforator (DAP) flap. Herein we report 13 DAP flaps for fingertip and finger stump reconstruction following traumatic finger amputations, highlighting modifications to the originally described DAP flap. From October 1998 to December 2007, a total of 13 fingers (11 patients) underwent fingertip and finger stump reconstruction with modified DAP flaps following traumatic finger amputations. We performed six adipocutaneous flaps, three adipose-only flaps, two supercharged flaps and two extended flaps. Flap size ranged from 1.44 to 8 cm(2) (average 3.25 cm(2)). All flaps survived completely with the exception of partial skin necrosis in two cases. One of these cases required debridement and skin grafting. Our initial three cases used donor-site skin grafting. The donor site was closed primarily in the 10 subsequent cases. No patients showed postoperative hypersensitivity of repaired fingertips. Semmes-Weinstein (SW) test result for flaps including a digital nerve branch did not differ from those without (average 4.07 vs. 3.92). Modified DAP flaps allow for preservation of digital length, volume and finger function. They can be raised as adiposal-only flaps or extended flaps and supercharged through perforator-to-perforator anastomoses. The donor defect on the lateral pulp can be closed primarily or by skin grafting. For traumatic fingertip and finger stump reconstructions, DAP flaps deliver consistent aesthetic and functional results.

    The reduction of the eleven-dimensional pure gravity to the field theory in the four-dimensional Minkowski space-time by means of the spontaneous compactification of the extra dimensions is investigated. The contribution of the quantum fluctuations of the eleven-dimen-- sonal second rank symmetric tensor field to the curvatures of the space-time and the compactified space of the extra dimensions are calculated in the one-loop approximation. It is shown that there exist the values of the cosmological constant for which tachions are absent. As a result, self-consistent quantum field theory is obtained in spontaneous compactified Minkowski space M 4 xS 7 ,is where M 4 is Minkowski space-time, and S 7 is seven-dimensional sphere

    The aim was to investigate first-care procedures for the newborn's umbilical cord at maternity hospitals in Slovenia and Croatia. The study was based on an empirical survey research approach and quantitative research paradigms and included all Slovenian (n=14) and all Croatian (n=35) maternity hospitals. Leaders of midwifery team of 14 Slovenian and 35 Croatian labor wards were invited to participate. The study was conducted in 2013, with 67% of Slovenian and 66% of Croatian maternity hospitals having responded. A causal and non-experimental method of empirical research was used. The research instrument was a questionnaire. Descriptive statistics was used on data analysis. The independence hypothesis was tested with the χ2-test or Kullback 2Î-test. A vast ma-jority of study wards employed delayed umbilical cord clamping, i.e. clamping the cord after pulsa-tion had ceased. Only 10% of Slovenian in comparison with 36.4% of Croatian maternity hospitals practiced dry cord care. Others applied disinfectant on the cord, in Slovenia most frequently 6% po-tassium permanganate, and in Croatia a combination of octenidine and phenoxyethanol. Most Croa-tian -maternity wards (95.7%) still covered the stump, while it was not regular practice in Slovenia. The authors estimate that the prevailing Slovenian and Croatian practices in regard to cord clamping are in accordance with the evidence, while improvements could be made regarding stump care, since dry cord care is the recommended method.

    Lung suppurative diseases in children are usually responsive to medical treatment or percutaneous drainage. Rarely, pulmonary resection is required for lung abscess in childhood, particularly in presence of co-morbidities. In these cases, a lobectomy is usually performed through an open thoracotomy, with a reported incidence of bronco-pleural fistula up to 9.1% of pediatric series. This consequence is mainly due to the inflammatory condition; however the lack of knowledge of pediatric and thoracic surgeons with this rare condition in childhood can also play a role. In adults with lung cancer, the buttressing of bronchial stump with the additional support of an intercostal muscle (ICM) flap has proved to prevent this complication, as well as to reduce post-operative pain. We report the first pediatric experience of ICM flap used in 2 immunocompetent children requiring lobectomy for suppurative lung conditions. Our preliminary experience confirms the feasibility of protecting the bronchial stump after lobectomy in children, especially in conditions at risk for bronco-pleural fistula development.

    An 18-month-old, neutered male beagle presented with acute abdominal signs and a suppurative infection of the urogenital tract. Chromosomal sex was female (78, XX), gonadal sex was male (testicles), and phenotypic sex was ambiguous, with evidence of both male and female duct systems. The internal and external genitalia consisted of epididymides, an underdeveloped uterus with an immature spermatic cord, communication between the uterus or cranial vagina and the membranous urethra, a urethrographically male urethra, a hypoplastic os penis, and a hypoplastic penis with hypospadia. Based on these findings and the familial history of a similarly affected litter mate, the dog was diagnosed as having the XX male syndrome with pyovagina and uterine stump pyometra. Radiographic and ultrasonographic investigations are described, and abnormalities of chromosomal sex, gonadal sex, and phenotypic sex are discussed

    Full Text Available Eleven Hevea brasiliensis clones were evaluated for clonal stability of latex yield. A randomized complete block design was used with four replicates, two locations, seven years and three periods per year. Stability analysis was based on clone x year and clone x year x location interactions. Five stability parameters viz environmental variance, shukla's stability variance, regression of clonal latex yield on environmental index, variance due to regression and variance due to deviation from regression were applied. There was significant clone x environment effect at the two levels of interaction. Among the eleven clones, C 162 was outstanding for clonal stability and it can serve as donor parent for stability alleles. Three clones (C 76, C 150 and C 154 were also stable. The four stable clones (C 76, C 150, C 154 and C 162 are suitable for broad-spectrum recommendation for latex yield. Five clones (C 83, C 143, C 163, C 202 and RRIM 600 will require environment-specific recommendation because of their unstable phenotype. The stability feature of two clones (C 145 and C 159 was not clear and this will be investigated in subsequent studies.

    We probe in some depth into the structure of eleven-dimensional, osp(32|1)-based Chern-Simons supergravity, as put forward by Troncoso and Zanelli (TZ) in 1997. We find that the TZ Lagrangian may be cast as a polynomial in 1/l, where l is a length, and compute explicitly the first three dominant terms. The term proportional to 1/l{sup 9} turns out to be essentially the Lagrangian of the standard 1978 supergravity theory of Cremmer, Julia and Scherk, thus establishing a previously unknown relation between the two theories. The computation is nontrivial because, when written in a sufficiently explicit way, the TZ Lagrangian has roughly one thousand non-explicitly Lorentz-covariant terms. Specially designed algebraic techniques are used to accomplish the results.

    Restorative proctocolectomy with ileopouch-anal anastomosis (IPAA) is the treatment of choice for intractable or complicated ulcerative colitis(UC). Elderly patients often present with acute colitis requiring emergent subtotal colectomy(SC). Frail patients are at risk of developing septic complications related to the closed rectosigmoidal stump, often requiring formation of a second stoma to be reversed at the time of completion proctectomy. This carries nuisance to such exhausted patients. We propose a simple and inexpensive trick to avoid the need for creating a mucous fistula. IPAA was performed as a 3-stage procedure in emergency settings. The rectosigmoidal stump was closed and placed subcutaneously; skin was closed over it. After SC, if patients showed signs of stump-related pelvic sepsis, a lavage of the rectal stump with povidone iodine solution and with saline was carried out as a rescue treatment aiming to avoid the need of opening the rectal stump to drain sepsis. Thirty-five patients underwent SC for UC between 1987 and 2012. The skin was closed over the closed stump in the 20. Seven patients out of these 20 experienced early stump-related septic complication. In five cases, we were able to avoid opening of the rectal stump, and a second stoma was unnecessary. After opening the closed stump in the remaining ones, a prompt improving of symptoms was observed. Rectal washout was well tolerated and avoided a second stoma in five out of seven patients, with better quality of life and body perception after IPAA surgery. This is relevant when dealing with geriatric patients, needing to completely recover before undergoing completion proctectomy.

    Full Text Available Summary: The reconstruction of defects around the knee often poses a challenge due to the limited availability of local soft tissues. Indeed, this same problem is encountered when attempting to revise a below-knee amputation stump. Moreover, due to a paucity of recipient vessels in those who have undergone previous amputation secondary to trauma, free-flap reconstruction is often challenging and not always successful. We report a case of a reverse anterolateral thigh (ALT flap used to revise a long below-knee amputation stump. Previous reports in the literature attest to the versatility of the reverse ALT to cover defects around the knee and proximal tibia, but to our knowledge, this is the first report of a reverse ALT reaching to the mid-tibial level.

    To assess the chronological changes in urinary incontinence and urethral function before and after radical prostatectomy (RP), and to compare the findings of pelvic magnetic resonance imaging (MRI) before and after RP to evaluate the anatomical changes. In total, 185 patients were evaluated with regard to the position of the distal end of the membranous urethra (DMU) on a mid-sagittal MRI slice and urethral sphincter function using the urethral pressure profilometry. The patients also underwent an abdominal leak point pressure test before RP and at 10 days and 12 months after RP. The results were then compared with the chronological changes in urinary incontinence. The MRI results showed that the DMU shifted proximally to an average distance of 4 mm at 10 days after RP and returned to the preoperative position at 12 months after RP. Urethral sphincter function also worsened 10 days after RP, with recovery after 12 months. The residual length of the urethral stump and urinary incontinence were significantly associated with the migration length of the DMU at 10 days after RP. The residual length of the urethral stump was a significant predictor of urinary incontinence after RP. This is the first study to elucidate that the slight vertical repositioning of the membranous urethra after RP causes chronological changes in urinary incontinence. A long urethral residual stump reduces urinary incontinence after RP. © 2018 The Authors BJU International © 2018 BJU International Published by John Wiley & Sons Ltd.

    Full Text Available This study presents the first investigation into the capability of fiber Bragg grating (FBG sensors to measure interface pressure between the stump and the prosthetic sockets of a trans-tibial amputee. FBG element(s were recoated with and embedded in a thin layer of epoxy material to form a sensing pad, which was in turn embedded in a silicone polymer material to form a pressure sensor. The sensor was tested in real time by inserting a heavy-duty balloon into the socket and inflating it by using an air compressor. This test was conducted to examine the sensitivity and repeatability of the sensor when subjected to pressure from the stump of the trans-tibial amputee and to mimic the actual environment of the amputee’s Patellar Tendon (PT bar. The sensor exhibited a sensitivity of 127 pm/N and a maximum FSO hysteresis of around ~0.09 in real-time operation. Very good reliability was achieved when the sensor was utilized for in situ measurements. This study may lead to smart FBG-based amputee stump/socket structures for pressure monitoring in amputee socket systems, which will result in better-designed prosthetic sockets that ensure improved patient satisfaction.

    The main objective of surgery, once amputation is inevitable, is to preserve a functional stump. This report describes the immediate reconstruction of 16 leg stumps in children by transfer of a functional calcaneo-plantar unit. Of these, 3 were thigh and 13 were lower leg reconstructions. Amputation was performed for tumor in 4 cases, and was due to accidents in the remaining twelve. The main technical features of flap preparation are preservation of the calcaneum branch and attachment of the heel skin to the greater tuberosity of the calcaneum. One case resulted in failure due to vascular thrombosis. The other 15 cases resulted in bone consolidation after an average of 45 days, sensitive protection by 70 days, and very good trophic and protective results. The provision of good distal pressure area encourages overall development of the child. There was no morbidity at the donor site, and because there is no major muscle mass in the distal fragment, the overall risk is very low compared to that of total proximal leg replantation. The transfer of functional calcaneo-plantar tissue as a single unit is the best strategy for one-step restoration of good distal support area for the stump. All surgeons liable to perform leg amputations should be aware of this technical approach.

    To determine the prevalence of arterial stump thrombosis (AST) after pulmonary resection surgery for lung cancer and to describe subsequent radiological follow-up and treatment. Observational, descriptive study of AST detected by computerized tomography angiography (CT) using intravenous contrast. Clinical and radiological variables were compared and a survival analysis using Kaplan-Meier curves was performed after dividing patients into 3 groups: patients with AST, patients with pulmonary embolism (PE), and patients without AST or PE. Nine cases of AST were detected after a total of 473 surgeries (1.9%), 6 of them in right-sided surgeries (67% of AST cases). Median time to detection after surgery was 11.3 months (interquartile range 2.7-42.2 months), and range 67.5 months (1.4-69.0 months). Statistically significant differences were found only in the number of CTs performed in AST patients compared to those without AST or PE, and in tumor recurrence in PE patients compared to the other 2 groups. No differences were found in baseline or oncological characteristics, nor in the survival analysis. In this series, AST prevalence was low and tended to occur in right-sided surgeries. Detection over time was variable, and unrelated to risk factors previous to surgery, histopathology, and tumor stage or recurrence. AST had no impact on patient survival. Copyright © 2016 SEPAR.

    2013-01-01

    A bioimpedance system for the continuous measurement of non-invasive physiological parameters in lower-limb amputees is presented. The aim of the system is to monitor as many physiological parameters as possible from a single bioimpedance electrode configuration. In this way, a simple, low-cost and low-size autonomous system is developed that is able to continuously monitor the amputee in different environments (home, work, etc). The system measures both electrical impedance myography and electrical impedance plethysmography in the stump with electrodes placed in the inside face of a silicone interface. Such a system allows for the monitoring of a patient's muscle activity, and heart and breath rate, thus enabling the study and continuous monitoring of prosthesis adaptation and improvement of patient's gait to reduce physiological stress. Additionally, it can prevent cardiovascular problems due to the effort involved in the use of prostheses, which can decrease the life expectancy of amputees with previous vascular diseases. Experimental results obtained from different amputees' test validate the purpose of the system. (paper)

    The aim of this clinical trial is to evaluate the influence of high and low ligation of the inferior mesenteric artery with apical lymph node dissection on the anastomotic blood supply, lymph node retrieval rate, operative time and anastomotic leakage rate in rectal cancer surgery. A total of 57 Chinese patients were randomly distributed into group A and group B and underwent radical resection of rectal cancer. Patients in group A underwent high ligation of the inferior mesenteric artery, and patients in group B underwent apical lymph node resection around the root of the inferior mesenteric artery with preservation of the left colic artery. The marginal artery stump pressure was measured after colon and artery reconstruction. Systemic pressure, distal colon length, operative time and lymph node retrieval rate were measured and recorded. The results were analysed and related to patient characteristics and post-operative complications. The anastomotic blood supply negatively and linearly correlated with age and distal colon length and showed a positive linear correlation with systemic pressure. Patients who received low ligation with apical lymph node dissection had a better anastomotic blood supply than those who received high ligation. No differences were found in lymph node retrieval rate, operative time and anastomotic leakage rate. Anastomotic leakage was associated with a worse anastomotic blood supply. Low ligation with apical lymph node dissection in rectal cancer treatment provides better anastomotic blood supply but is not associated with differences in node retrieval rate or operation time. © 2015 Royal Australasian College of Surgeons.

    2012-01-01

    One of the objectives of designing feature selection learning algorithms is to obtain classifiers that depend on a small number of attributes and have verifiable future performance guarantees. There are few, if any, approaches that successfully address the two goals simultaneously. To the best of our knowledge, such algorithms that give theoretical bounds on the future performance have not been proposed so far in the context of the classification of gene expression data. In this work, we investigate the premise of learning a conjunction (or disjunction) of decision stumps in Occam's Razor, Sample Compression, and PAC-Bayes learning settings for identifying a small subset of attributes that can be used to perform reliable classification tasks. We apply the proposed approaches for gene identification from DNA microarray data and compare our results to those of the well-known successful approaches proposed for the task. We show that our algorithm not only finds hypotheses with a much smaller number of genes while giving competitive classification accuracy but also having tight risk guarantees on future performance, unlike other approaches. The proposed approaches are general and extensible in terms of both designing novel algorithms and application to other domains.

    First, we review a result in our previous paper, of how a ten-dimensional superparticle, taken off-shell, has a hidden eleven-dimensional superPoincare symmetry. Then, we show that the physical sector is defined by three first-class constraints which preserve the full eleven-dimensional symmetry. Applying the same concepts to the eleven dimensional superparticle, taken off-shell, we discover a hidden twelve dimensional superPoincare symmetry that governs the theory.

    Full Text Available Ectodermal dysplasia represents a rare syndrome affecting two or more ectodermally derived structures. The condition is thought to occur in approximately 1 in every 100,000 live births. It affects men more frequently and severely, while women being the carriers and heterozygote usually show minor defects. There are more than 150 different variants of ectodermal dysplasia (ED reported in the literature. Most commonly encountered among them is hypohidrotic ED which frequently exhibits the most severe dental anomalies like hypodontia or anodontia along with hypohidrosis and hypotrichosis. Here we make an attempt to collectively report and discuss eleven South Indian patients who reported to our department during the year 1998 to 2004. An added emphasis is laid on family history of consanguineous marriage among the parents of these patients.

    Speech is unique to humans and characterized by facial actions of ∼5 Hz oscillations of lip, mouth or jaw movements. Lip-smacking, a facial display of primates characterized by oscillatory actions involving the vertical opening and closing of the jaw and lips, exhibits stable 5-Hz oscillation patterns, matching that of speech, suggesting that lip-smacking is a precursor of speech. We tested if facial or vocal actions exhibiting the same rate of oscillation are found in wide forms of facial or vocal displays in various social contexts, exhibiting diversity among species. We observed facial and vocal actions of wild stump-tailed macaques (Macaca arctoides), and selected video clips including facial displays (teeth chattering; TC), panting calls, and feeding. Ten open-to-open mouth durations during TC and feeding and five amplitude peak-to-peak durations in panting were analyzed. Facial display (TC) and vocalization (panting) oscillated within 5.74 ± 1.19 and 6.71 ± 2.91 Hz, respectively, similar to the reported lip-smacking of long-tailed macaques and the speech of humans. These results indicated a common mechanism for the central pattern generator underlying orofacial movements, which would evolve to speech. Similar oscillations in panting, which evolved from different muscular control than the orofacial action, suggested the sensory foundations for perceptual saliency particular to 5-Hz rhythms in macaques. This supports the pre-adaptation hypothesis of speech evolution, which states a central pattern generator for 5-Hz facial oscillation and perceptual background tuned to 5-Hz actions existed in common ancestors of macaques and humans, before the emergence of speech. © 2017 Wiley Periodicals, Inc.

    Full Text Available OBJETIVO: Apresentação do perfil epidemiológico das patologias fonoaudiológicas de fala e linguagem, de causa idiopática, especificamente relacionado à prevalência dessas desordens na população infantil de 1 a 11 anos de idade. MÉTODO: As crianças foram avaliadas nos aspectos de fala, linguagem e sistema miofuncional oral. Estabelecido o diagnóstico fonoaudiológico, foram os mesmos classificados segundo a manifestação predominante. Após agrupadas as categorias das desordens, foram diferenciadas as idades e aplicados os cálculos de prevalência. RESULTADOS: De um total de 2.980 crianças, 125 delas eram portadoras de desordens fonoaudiológicas (prevalência de 4,19. A prevalência geral mais elevada foi referente à faixa etária de 3 a 8 anos, sendo a fase crítica dos 4 aos 5 anos. As patologias de manifestação primária mais prevalentes foram, em ordem de freqüência: distúrbios articulatórios, defasagens na aquisição e desenvolvimento da linguagem oral e desordens miofuncionais orais e de funções neuro vegetativas. CONCLUSÃO: As desordens fonoaudiológicas constituem importante segmento nos agravos à saúde infantil, sendo necessário que sejam urgentemente estruturados programas fonoaudiológicos preventivos e curativos. Em sua precariedade, o sistema de saúde brasileiro não oferece uma rede de apoio para o atendimento aos portadores de patologias da comunicação, existindo apenas esforços isolados em algumas unidades de saúde.OBJECTIVE: The study of the epidemiological aspect of speech-language idiopathic disorders.

    Postoperative pancreatic fistula (POPF) is the most common cause of morbidity and mortality after distal pancreatectomy (DP). The aim of the present study is to determine the risk factors that can lead to POPF. The study was conducted between January 2008 and December 2012. A total of 96 patients who underwent DP were retrospectively analyzed. Overall, 24 patients (25%) underwent laparoscopic distal pancreatectomy (LDP) and 72 patients (75%) open surgery. The overall morbidity rate was 51% (49/96). POPF (32/96, 33.3%) was the most common postoperative complication. Grade B fistula (18/32, 56.2%) was the most common fistula type according to the International Study Group on Pancreatic Fistula definition. POPF rate was significantly higher in the minimally invasive surgery group (50%, p=0.046). POPF rate was 58.6% (17/29) in patients whose pancreatic stump closure was performed with only stapler, whereas POPF rate was 3.6% (1/28) in the group where the stump was closed with stapler plus oversewing sutures. Both minimally invasive surgery (OR: 0.286, 95% CI: 0.106-0.776, p=0.014) and intraoperative blood transfusion (OR: 4.210, 95% CI: 1.155-15.354, p=0.029) were detected as independent risk factors for POPF in multi-variety analysis. LDP is associated with a higher risk of POPF when stump closure is performed with only staplers. Intraoperative blood transfusion is another risk factor for POPF. On the other hand, oversewing sutures to the stapler line reduces the risk of POPF.

    Full Text Available Introduction: The phantom limb pain (PLP and phantom limb sensation (PLS are very common among amputated cancer patients, and they lead to considerable morbidity. In spite of this, there is a lack of epidemiological data of this phenomenon among the Asian population. This study was done to provide the data from Indian population. Methods: The prevalence of PLP, stump pain (SP, and PLS was prospectively analyzed from the amputated cancer patients over a period of 2 years in Dr. B.R.A. Institute Rotary Cancer Hospital, All India Institute of Medical Sciences, New Delhi. The risk factors and the impact of phantom phenomenon on patients were also noted. Results: The prevalence of PLP was 41% at 3 and 12 months and 45.3% at 6 months, whereas that of SP and PLS was 14.4% and 71.2% at 3 months, 18.75% and 37.1% at 6 months, 15.8% and 32.4% at 12 months, respectively. There was higher prevalence of PLP and PLS among the patients with history of preamputation pain, smoking with proximal level of amputation, receiving general anesthesia, receiving intravenous (IV opioid postoperative analgesia, and developing neuroma or infection. Conclusion: The prevalence of PLP and PLS was higher among the cancer amputees as compared to SP, and a few risk factors responsible for their higher prevalence were found in our study. The PLP and PLS lead to considerable morbidity in terms of sleep disturbance and depression.

  12. Reading Very Well for Our Age: Hyperobject Metadata and Global Warming in Emily St. John Mandel’s Station Eleven

    Directory of Open Access Journals (Sweden)

    2018-02-01

    Full Text Available In recent years, the practices of symptomatic reading have been called into question by scholars such as Stephen Best, Sharon Marcus, Cathy N. Davidson, David Theo Goldberg, Rita Felski and Bruno Latour. It is claimed that such reading has become either formulaic or politically inefficacious. This article argues, against such thinking, that Emily St. John Mandel’s Arthur C. Clarke award–winning novel 'Station Eleven' (2014 presents several challenges for an age of so-called post-critical reading. Given that this novel is, in some ways, about how the future will ‘read’ our present, I use the metaphor of ‘metadata’ here to think through the series of ruined objects in 'Station Eleven' that project a hyperobject-like extent across two epistemic contexts. I argue that this is a comment on interpretative reading practices and an invitation for politicised symptomatic readings of the novel. Using this approach, I show that 'Station Eleven' is a novel that is deeply concerned with global warming and with colonial nationalist legacies, even while such concerns appear buried—or even absent—within the novel. If one takes the novel’s surface instruction to look for ‘another world just out sight’, these concerns of the early twenty-first century emerge as central to the forking futures of Mandel’s work.

    Full Text Available When dealing with gastric cancer with duodenal invasion, gastrectomy with distal resection of the duodenum is necessary to achieve negative distal margin. However, rupture of an ultralow duodenal stump necessitates advanced surgical skills and close postoperative observation. The present study reports a case of an early duodenal stump rupture after subtotal gastrectomy with resection of the whole first part of the duodenum, complete omentectomy, bursectomy, and D2+ lymphadenectomy performed for a pT3pN2pM1 (+ number 13 lymph nodes adenocarcinoma of the antrum. Duodenal stump rupture was managed successfully by end tube duodenostomy, without omental patching, and tube cholangiostomy. Close assessment of clinical, physical, and radiological signs, output volume, and enzyme concentration of the tube duodenostomy, T-tube, and closed suction drain, which was placed near the tube duodenostomy site to drain the leak around the catheter, dictated postoperative management of the external duodenal fistula.

  2. On the appearance of acetylcholine receptors in denervated rat diaphragm, and its dependence on nerve stump length

    International Nuclear Information System (INIS)

    Uchitel, O.; Robbins, N.

    1978-01-01

    Acetylcholine (ACh) sensitivity and extrajunctional receptor distribution of the rat diaphragm were closely monitored during the early period following denervation. Both contracture in response to 10 μg/ml of ACh and extrajunctional binding of [ 125 I]alpha-bungarotoxin ([ 125 I]α-BTX) were first detectable 30 h after cutting the phrenic nerve in the thorax. If the nerve were cut more proximally, leaving a 3.5 cm distal nerve stump, the same level of ACh contracture and [ 125 I]α-BTX binding did not appear until 40 h after operation. This 10-h delay was far longer than the 3-h delay in transmission failure reportedly dependent on stump length. The earliest detectable extrajunctional [ 125 I]α-BTX binding appeared throughout the entire muscle fiber, and was not localized to the endplate region as would be expected if degeneration in the nerve terminal induced new receptors. However, later significant increases in [ 125 I]α-BTX binding at the endplate region could have resulted from such degeneration. All these results are consistent with neurotrophic regulation of muscle ACh receptors, working via a mechanism involving axonal transport. (Auth.)

    Osteogenesis imperfecta (OI) type V is a rare inherited disease characterized by multiple fractures, intraosseous membrane calcification, and hypercallus formation. We investigate the causative gene, phenotype and also observe the effects of zoledronic acid in Chinese OI type V patients. The clinical phenotype and causative gene mutation was investigated in eleven patients with type V OI. Patients were given a dose of zoledronic acid 5mg intravenously. Fracture incidence and Z-score of bone mineral density (BMD) were evaluated. Serum levels of biomarkers such as cross linked C-telopeptide of type I collagen (β-CTX) and safety parameters were assessed. The c.-14C>T mutation in the 5' untranslated region of IFITM5 was detected in all patients. The phenotype was largely variable, and no significant correlation of genotype and phenotype was found. After one dose of zoledronic acid infusion, fracture incidence significantly dropped from 2fractures/year before treatment to 0fracture/year after treatment (P=0.01). Z score of lumbar spine BMD elevated from -2.6 to -1.3 (P<0.001). Serum β-CTX level decreased by 50% (P<0.05). No serious adverse event was found. No obvious correlation was found between the genotype and phenotype. Zoledronic acid had significantly skeletal protective effects in OI of type V. Copyright © 2016 Elsevier B.V.

    Full Text Available Safety of either LigaSure or rubber band in closing inflamed appendiceal stump in acute appendicitis has been less investigated. In this study, cecal ligation followed by resecting inflamed cecum was performed to mimic appendectomy in a rat model of acute appendicitis. Rats were sacrificed immediately (Group A and 7 days (Group B after cecal resection, respectively. The cecal stumps were closed by silk ligature (S, 5 mm LigaSure (L, or rubber band (R. Seven days after cecal resection, the LigaSure (BL and silk subgroups (BS had significantly less intra-abdominal adhesion and better laparotomy wound healing than rubber band subgroup (BR. The initial bursting pressure at cecal stump was comparable among the three methods; along with tissue healing process, both BL and BS provided a higher bursting pressure than BR 7 days after appendectomy. BL subgroup had more abundant hydroxyproline deposition than BS and BR subgroup. Furthermore, serum TNF-α in BR group kept persistently increasing along with time after cecal resection. Thus, the finding that LigaSure but not rubber band is safe in sealing off the inflamed cecal stump in rat model of acute appendicitis suggests the possibility of applying LigaSure for appendectomy via single port procedure or natural orifice transluminal endoscopic surgery (NOTES.

    This study aimed to find out whether preoperative diffusion tensor imaging (DTI) and probabilistic tractography could help with surgical planning for deep brain stimulation in the periaqueductal/periventricular grey area (PAG/PVG) in a patient with lower leg stump pain. A preoperative DTI was obtained from the patient, who then received DBS surgery in the PAG/PVG area with good pain relief. The postoperative MRI scan showing electrode placement was used to calculate four seed areas to represent the contacts on the Medtronic 3387 electrode. Probabilistic tractography was then performed from the pre-operative DTI image. Tracts were seen to connect to many areas within the pain network from the four different contacts. These initial findings suggest that preoperative DTI scanning and probabilistic tractography may be able to assist surgical planning in the future.

    Participation and performance trends in age group athletes have been investigated in endurance and ultraendurance races in swimming, cycling, running, and triathlon, but not in long-distance inline skating. The aim of this study was to investigate trends in participation, age, and performance in the longest inline race in Europe, the Inline One-Eleven over 111 km, held between 1998 and 2009. The total number, age distribution, age at the time of the competition, and race times of male and female finishers at the Inline One-Eleven were analyzed. Overall participation increased until 2003 but decreased thereafter. During the 12-year period, the relative participation in skaters younger than 40 years old decreased while relative participation increased for skaters older than 40 years. The mean top ten skating time was 199 ± 9 minutes (range: 189-220 minutes) for men and 234 ± 17 minutes (range: 211-271 minutes) for women, respectively. The gender difference in performance remained stable at 17% ± 5% across years. To summarize, although the participation of master long-distance inline skaters increased, the overall participation decreased across years in the Inline One-Eleven. The race times of the best female and male skaters stabilized across years with a gender difference in performance of 17% ± 5%. Further studies should focus on the participation in the international World Inline Cup races.

    Full Text Available Background: Acute disseminated encephalomyelitis (ADEM is an inflammatory demyelinating disorder. The pathogenesis is unclear, but it is thought to be immune-mediated. The prognosis is favorable, with most children making a full recovery. Objectives: The present report analyzed different clinical presentations, response to treatment and outcome in a series of 11 patients with ADEM who referred to our tertiary center in north of Iran from 2010 to 2014. Materials and Methods: In this retrospective simple descriptive review, eleven cases with ADEM admitted in the neurology ward from 2010 to 2014 were enrolled. The clinical findings and laboratory and imaging results of patients were reviewed. All of these cases were evaluated with neurological examination, serologic tests for bacterial meningitis and viral encephalitis (especially, herpes simplex virus and brain MRI without contrast. After discharge, patients were followed for at least six months (6 to 12 months clinically and radiologically. Results: Of 11 children, 8 were male and 3 female. Their ages ranged between 4 and 10 years. The mean interval between the preceding infection and symptoms of encephalomyelitis was nine days. The most common presenting symptoms were ataxia in 45.4%, fever and headache in 36.4% and altered consciousness in 18.2% of patients. Neurological examination revealed pyramidal motor signs such as brisk deep tendon reflexes (hyperreflexia (81.8%, cranial nerve involvement (18.2%, dysarthria (9.1% and abnormal movements (9.1%. We followed up these patients in long-term for 6 to 12 months. Only in 1 child who received IVIG, mild ataxia had reminded. Conclusions: The prognosis of acute disseminated encephalomyelitis (ADEM is favorable. Early diagnosis and prompt treatment of ADEM would probably reduce morbidity.

    Depression is one of the most prevalent mental disorders in later life. However, despite considerable research attention, great confusion remains regarding the association between ageing and depression. There is doubt as to whether a depression scale performs identically for different age groups and countries. Although measurement equivalence is a crucial prerequisite for valid comparisons across age groups and countries, it has not been established for the eight-item version of the Centre for Epidemiological Studies Depression Scale (CES-D8). Using multi-group confirmatory factor analysis, we assess configural, metric, and scalar measurement equivalence across two age groups (50-64 years of age and 65 or older) in eleven European countries, employing data from the Survey of Health, Ageing, and Retirement (SHARE). Results indicate that the construct of depression is comparable across age and country groups, allowing the substantive interpretation of correlates and mean levels of depressive symptoms.

    Dystrophic epidermolysis bullosa is a rare disease characterized by widespread blistering of the skin and mucous membranes, which may ultimately prompt limb amputation. In this context, the outcome of fitting a prosthesis to a chronically wounded stump is not well known. Our patient's experience (with 15 years of follow-up) should contribute to better knowledge of this topic. A 37-year-old man presented with severe dystrophic epidermolysis bullosa. Recurrent skin carcinoma had led to an amputation below the knee. Despite incessant development of blisters on the stump and the need for wound dressing and padding, the patient has been able to walk freely with a prosthesis and a cane. A large number of skin sarcomas were excised over the 15-year period of prosthesis use. Two falls have resulted in limb fractures. A new sarcoma on the stump marked the end of the use of the prosthesis. Despite the constant presence of wounds on the stump, amputees with dystrophic epidermolysis bullosa can successfully be fitted with a prosthesis.

  3. Performance Evaluation of Eleven-Phase Induction Machine with Different PWM Techniques

    Full Text Available Multiphase induction machines are used extensively in low and medium voltage (MV drives. In MV drives, power switches have a limitation associated with switching frequency. This paper is a comparative study of the eleven-phase induction machine’s performance when used as a prototype and fed sinusoidal pulse-width-modulation (SPWM with a low switching frequency, selective harmonic elimination (SHE, and single pulse modulation (SPM techniques. The comparison depends on voltage/frequency controls for the same phase of voltage applied on the machine terminals for all previous techniques. The comparative study covers torque ripple, stator and harmonic currents, and motor efficiency.

  4. Renewable energy clusters recurring barriers to cluster development in eleven countries

    2017-01-01

    Taking eleven countries in Europe, Canada, South Africa, America, Latin America and Australia, this book discusses recurring barriers to cluster development in the renewable energy sector. The authors look at the real-world dynamics and tensions between stakeholders on the ground, with a particular focus on the relationships between SMEs and other actors. This trans-regional study is unique in its scale and scope, drawing on a decade of field research to show how by learning from the successes and failures of other clusters, costs and risk can be reduced. The book fills a significant gap in the literature for policymakers, managers and economic developers in a key market.

    1979-01-01

    Spectrophotometry of eleven HgMn stars is presented for the optical region. As found in Paper I, the HgMn stars have systematically larger Δiota* and Δa values than the normal main sequence stars due to differences with respect to the mean continuum particularly of the lambda4464 values and the lambda5200 region, respectively. The HgMn stars exhibit a continuous range in the behavior of both the lambda4200 and lambda5200 regions between those stars that have index values larger than the appropriate criterion of presence and present definite evidence for the features to those stars with only a slight possibility of such features. The strengths of the lambda4200 and lambda5200 features appear not to be correlated. In the HgMn stars, both features may be due to differential line blocking. In the energy distribution of all eleven stars, the Balmer jump regions best fit the predictions of slightly hotter solar composition, log g=4.0, fully line blanketed model atmospheres than do the corresponding Paschen continua

    These lectures are intended to be an introduction to the physics of the quark-gluon plasma, and were presented at a workshop on The Physics of the Quark-Gluon Plasma held at Hua-Zhong Normal University in Wuhan, People's Republic of China in September, 1983. The lectures cover perturbation theory of the plasma at high temperature as well as the non-perturbative methods and results of lattice gauge theory computations. Physical models of the confinement-deconfinement phase transition and the modes of chiral symmetry breaking are presented. The possibility that a quark-gluon plasma might be produced in ultra-relativistic nuclear collisions is analyzed. Separate entries were prepared for the data base for the eleven lectures

    Eleven species of wild mushrooms which belong to Boletaceae and Russulaceae families were examined by gas chromatography (GC) and gas chromatography-mass spectrometry (GC/MS) analysis for the presence of fatty acids. As far as we know, the fatty acid profiles of B. purpureus and B. rhodoxanthus were described for the first time. Twenty-six fatty acids were determined. Linoleic (19.5 - 72%), oleic (0.11 - 64%), palmitic (5.9 - 22%) and stearic acids (0.81 - 57%) were present in the highest contents. In all samples, unsaturated fatty acids dominate. Agglomerative hierarchical clustering was used to display the correlation between the fatty acids and their relationships with the mushroom species. Based on the fatty acids profile in the samples, the mushrooms can be divided into two families: Boletaceae and Russulaceae families, using cluster analysis. © 2018 Wiley-VHCA AG, Zurich, Switzerland.

    Pay for success (PFS) is a type of social impact investing that uses private capital to finance proven prevention programs that help a government reduce public expenditures or achieve greater value. We conducted an analysis of the first eleven PFS projects in the United States to investigate the potential of PFS as a strategy for financing and disseminating interventions aimed at improving population health and health equity. The PFS approach has significant potential for bringing private-sector resources to interventions regarding social determinants of health. Nonetheless, a number of challenges remain, including structuring PFS initiatives so that optimal prevention benefits can be achieved and ensuring that PFS interventions and evaluation designs are based on rigorous research principles. In addition, increased policy attention regarding key PFS payout issues is needed, including the "wrong pockets" problem and legal barriers to using federal Medicaid funds as an investor payout source.

  9. Teaching Process Simulation in Eleven Easy Lessons Using Excel and Its Tools

    Science.gov (United States)

    Morris, Arthur E.

    The primary market driver for improving process technology is innovation, which requires a skilled and educated workforce. However, many Materials Science and Engineering departments have eliminated extractive metallurgy and chemical thermodynamics from their curricula, yet these topics contain the necessary fundamentals for process innovation. As a result, most MS&E students are ill-prepared for careers in processing. The dearth of process-oriented MS&E curricula has prompted some Universities to develop a "shared" effort to offer distance education between multiple institutions [1]. A target audience for a shared process simulation course would not only benefit students, but also be a basis for an on-line course for practicing engineers faced with new or changing career choices. To fill the gap, the basics of a process simulation course was developed in an abbreviated form as series of eleven articles and Excel workbooks published in Industrial Heating magazine between July 2012 and July 2013.

  10. Characterization of potential zones of dust generation at eleven stations in the southern Sahara

    Clark, I.; Assamoi, P.; Bertrand, J.; Giorgi, F.

    Synoptic wind data for multi-decadal periods at eleven stations located in the southern Sahara region (Agadez, Atar, Bilma, Dori, Gao, Kayes, Nema, Niamey, Nouadhibou, Ouagadougou and Tessalit) are used to study the monthly dust deflation power over the region. We found that, regardless of the conditions of the soil, the deflation power (or wind efficiency) is not sufficient to generate significant amounts of aerosols south of 15°N. North of this latitude, the deflation power is much larger, with potential zones of either very strong deflation (Nouadhibou and Bilma) or severe deflation (Gao, Tessalit, Nema, Atar, Agadez). Stations in the Sahel region such as Gao, Agadez and Tessalit are characterized by a gradual reinforcement of the deflation power between 1970 and 1984 in correspondence of increasing desertification over the region. During this same period, Bilma, a well know region of dust source, experienced a major reduction in deflation power due to shifts in large scale wind patterns.

    1973-01-01

    Eleven plant species were exposed to ozone and/or sulfur dioxide to determine if a mixture of the two gases enhanced foliar injury. Tobacco, radish, and alfalfa developed more injury that the additive injury of the single gases. In other species, such as cabbage, broccoli, and tomato, the foliar injury from mixed-gas exposures was additive or less than additive. Leaf injury from the ozone/sulfur dioxide mixture appeared as upper surface flecking, stipple, bifacial necrosis, and lower surface glazing and, in general, appeared similar to injury from oxidant or ozone. The concentrations of ozone and sulfur dioxide that caused plant injury were similar to those found in urban areas. These concentrations may result in yield losses to plants grown under field conditions.

    Smoking among university students represents a formidable and global public health challenge. We assessed the associations between socio-demographic, health and wellbeing variables as independent variables, with daily smoking, attempts to quit smoking, and agreement with smoking ban as dependent variables. A sample of 3258 undergraduate students from eleven faculties at Assiut University, Assiut, Egypt, completed a general health questionnaire. Overall daily or occasional smoking in last three months prior to the survey was about 9% (8% occasional and 1% daily smokers), and smoking was generally more prevalent among males (male=17%, female=0.6%, P non-smoking policies on university premises, as well as regular up-to-date information on, and the periodic/yearly monitoring of tobacco use by university students employing standardised data collection instruments and reference periods. In addition, it would be valuable to develop campus-based educational/ awareness campaigns designed to counteract tobacco advertisement directed towards young people in Middle East countries. Otherwise, the danger could be that the current relatively low smoking prevalence among university students may escalate in the future.

  13. Health care usage among immigrants and native-born elderly populations in eleven European countries: results from SHARE

    2013-01-01

    Differences in health care utilization of immigrants 50 years of age and older relative to the native-born populations in eleven European countries are investigated. Negative binomial and zero-inflated Poisson regression are used to examine differences between immigrants and native-borns in number of doctor visits, visits to general practitioners, and hospital stays using the 2004 Survey of Health, Ageing, and Retirement in Europe database. In the pooled European sample and in some individual countries, older immigrants use from 13 to 20% more health services than native-borns after demographic characteristics are controlled. After controlling for the need for health care, differences between immigrants and native-borns in the use of physicians, but not hospitals, are reduced by about half. These are not changed much with the incorporation of indicators of socioeconomic status and extra insurance coverage. Higher country-level relative expenditures on health, paying physicians a fee-for-service, and physician density are associated with higher usage of physician services among immigrants.

    Full Text Available Background: Although gracilis muscle transposition for faecal incontinence has been well-described method, its literature for use in obstetric perineal tear without colostomy is sparse. In this study, we have tried to analyse its use in fourth-degree obstetric perineal tears. Patients and Methods: A total of 30 patients with recto-vaginal fistula with faecal incontinence secondary to obstetric perineal tear were retrospectively studied between February 2003 and May 2014. The recto-vaginal fistula was explored, dissected and identification of sphincters was done using muscle stimulator. Fistula closure was done followed by sphincter repair, vaginal tightening procedure and single gracilis transposition. None of the patients had covering colostomy. Faecal incontinence was assessed pre- and post-operatively by digital rectal examination (single examiner, Park's score and Corman's score in all cases and using barium hold and transperineal ultrasonography, manometric studies in a few cases. The outcome was measured at an average follow-up of 8.8 months (7–24 months. Results: As per Park's score 26 patients had Grade I continence, two had Grade II and two patients had Grade III continence. Corman's score improved from fair to excellent in 26 patients. The patients in whom manometry was performed showed a remarkable rise in both resting and squeeze pressures. Two patients developed post-operative infections in upper 1/3 thigh incision site and three patients at gluteal region scar site. Conclusion: Satisfactory continence following gracilis muscle could be achieved.

    The paper deals with the multilevel converters control strategy for photovoltaic system integrated in distribution grids. The objective of the proposed work is to design multilevel inverters for solar energy applications so as to reduce the Total Harmonic Distortion (THD) and to improve the power quality. The multilevel inverter power structure plays a vital role in every aspect of the power system. It is easier to produce a high-power, high-voltage inverter with the multilevel structure. The topologies of multilevel inverter have several advantages such as high output voltage, lower total harmonic distortion (THD) and reduction of voltage ratings of the power semiconductor switching devices. The proposed control strategy ensures an implementation of selective harmonic elimination (SHE) modulation for eleven levels. SHE is a very important and efficient strategy of eliminating selected harmonics by judicious selection of the firing angles of the inverter. Harmonics elimination technique eliminates the need of the expensive low pass filters in the system. Previous research considered that constant and equal DC sources with invariant behavior; however, this research extends earlier work to include variant DC sources, which are typical of lead-acid batteries when used in system PV. This Study also investigates methods to minimize the total harmonic distortion of the synthesized multilevel waveform and to help balance the battery voltage. The harmonic elimination method was used to eliminate selected lower dominant harmonics resulting from the inverter switching action.

    Endoscopic placement of self-expandable metallic stents is reportedly effective for gastric outlet obstructions due to advanced gastric cancer, and is less invasive than gastrojejunostomy. For patients who have good performance status, we administer chemotherapy after stent placement, although the safety and feasibility of this chemotherapy have not yet been discussed in full. Between 2011 and 2015, 15 patients at our institution underwent endoscopic gastroduodenal stent placement for gastric outlet obstruction due to gastric cancer. Eleven of these patients were administered chemotherapy after stent placement. In our case series, we did not observe any specific adverse event caused by stent placement plus chemotherapy. Adverse events after chemotherapy included anemia of CTCAE Grade 3 in 7 patients. Stent-in-stent placement was needed in 2 patients. Neither stent migration nor perforation was observed. Therefore, chemotherapy after stent placement for gastric outlet obstruction due to gastric cancer was considered safe and feasible. Stent placement is useful not only as palliative care for patients with terminal-stage disease, but also as one of the multimodal therapeutic strategies for gastric cancer.

  1. Analysis of uranium urinalysis and in vivo measurement results from eleven participating uranium mills

    1984-05-01

    Uranium urinalysis and in vivo examination results obtained from workers at eleven uranium mills between 1978 and 1980 were evaluated. The main purpose was to determine the degree of the mills' compliance with bioassay monitoring recommendations given in the draft NRC Regulatory Guide 8.22 (USNRC 1978). The effect of anticipated changes in the draft regulatory guidance, as expressed to PNL in May 1982, was also studied. Statistical analyses of the data showed that the bioassay results did not reliably meet the limited performance criteria given in the draft regulatory guide. Furthermore, quality control measurements of uranium in urine indicated that detection limits at α = β = 0.05 ranged from 13 μg/l to 29 μg/l, whereas the draft regulatory guidance suggests 5 μg/l as the detection limit. Recommendations for monitoring frequencies given in the draft guide were not followed consistently from mill to mill. The results of these statistical analyses indicate a need to include performance criteria for accuracy, precision, and confidence in revisions of the draft Regulatory Guide 8.22. Revised guidance should also emphasize the need for each mill to continually test the laboratory performing urinalyses by submitting quality control samples (i.e., blank and spiked urine samples as open and blind test) to insure that the performance criteria are being met. Recommendations for a bioassay audit program are also given. 25 references, 15 figures, 17 tables

    Full Text Available Six Sigma combines managerial factors with statistical tools and is deployed in many enterprises today. Rio Grande do Sul is a Brazilian state that has a great industrialization, especially in the metropolitan area of Porto Alegre. Some of these industries have deployed the Six Sigma program. The aim of this paper is to present characteristics of the Six Sigma program in companies located in this region, through an exploratory study. A literature review subsidized the development of the questionnaire. Eleven companies participated of research in July and August 2008. It used statistical tools and qualitative analysis to analyze the results. Most of the companies that participated is classified as large and uses the DMAIC method to implement Six Sigma. The principal cause of program implementation was process improvement. In only one company the Six Sigma is implemented in all sectors, including administrative areas. Another result is the lack of clearly criteria for defining the career of Belts and the discrepancy of academic formation of these specialists.

  3. Human locognosic acuity on the arm varies with explicit and implicit manipulations of attention: implications for interpreting elevated tactile acuity on an amputation stump.

    2001-06-01

    In Experiment 1, normal subjects' ability to localize tactile stimuli (locognosia) delivered to the upper arm was significantly higher when they were instructed explicitly to direct their attention selectively to that segment than when they were instructed explicitly to distribute their attention across the whole arm. This elevation of acuity was eliminated when subjects' attentional resources were divided by superimposition of an effortful, secondary task during stimulation. In Experiment 2, in the absence of explicit attentional instruction, subjects' locognosic acuity on one of three arm segments was significantly higher when stimulation of that segment was 2.5 times more probable than that of stimulation of the other two segments. We surmise that the attentional mechanisms responsible for such modulations of locognosic acuity in normal subjects may contribute to the elevated sensory acuity observed on the stumps of amputees.

    The discovery of fossil rooted tree stumps in lowermost Lower Bed I from the western Olduvai Basin, Tanzania, age-bracketed by the Naabi Ignimbrite (2.038 ± 0.005 Ma) and Tuff IA (1.88 ± 0.05 Ma), provides the first direct, in situ, and to date oldest evidence of living trees at Olduvai Gorge. The tree relicts occur in an interval dominated by low-viscosity mass flow and braided fluvial sediments, deposited at the toe of a largely Ngorongoro Volcano-sourced volcaniclastic fan apron that comprised a widely spaced network of ephemeral braided streams draining northward into the Olduvai Basin. Preservation of the trees occurred through their engulfment by mass flows, post-mortem mold formation resulting from differential decay of woody tissues, and subsequent fluvially-related sediment infill, calcite precipitation, and cast formation. Rhizolith preservation was triggered by the interaction of root-induced organic and inorganic processes to form rhizocretionary calcareous root casts. Phytolith analyses were carried out to complete the paleoenvironmental reconstruction. They imply a pronounced seasonality and indicate a wooded landscape with grasses, shrubs, and sedges growing nearby, comparable to the low, open riverine woodland (unit 4c) along the Garusi River and tributaries in the Laetoli area. Among the tree stump cluster were found outsized lithic clasts and those consisting of quartzite were identified as Oldowan stone tool artifacts. In the context of hominin activity, the identification of wooded grassland in association with nearby freshwater drainages and Oldowan artifacts significantly extends our paleoenvironmental purview on the basal parts of Lower Bed I, and highlights the hitherto underrated role of the yet poorly explored western Olduvai Gorge area as a potential ecologically attractive setting and habitat for early hominins.

    Background Participation and performance trends in age group athletes have been investigated in endurance and ultraendurance races in swimming, cycling, running, and triathlon, but not in long-distance inline skating. The aim of this study was to investigate trends in participation, age, and performance in the longest inline race in Europe, the Inline One-Eleven over 111 km, held between 1998 and 2009. Methods The total number, age distribution, age at the time of the competition, and race times of male and female finishers at the Inline One-Eleven were analyzed. Results Overall participation increased until 2003 but decreased thereafter. During the 12-year period, the relative participation in skaters younger than 40 years old decreased while relative participation increased for skaters older than 40 years. The mean top ten skating time was 199 ± 9 minutes (range: 189–220 minutes) for men and 234 ± 17 minutes (range: 211–271 minutes) for women, respectively. The gender difference in performance remained stable at 17% ± 5% across years. Conclusion To summarize, although the participation of master long-distance inline skaters increased, the overall participation decreased across years in the Inline One-Eleven. The race times of the best female and male skaters stabilized across years with a gender difference in performance of 17% ± 5%. Further studies should focus on the participation in the international World Inline Cup races. PMID:23690697

  7. Otolith Length-Fish Length Relationships of Eleven US Arctic Fish Species and Their Application to Ice Seal Diet Studies

    2016-02-01

    The Arctic ecosystem has moved into the spotlight of scientific research in recent years due to increased climate change and oil and gas exploration. Arctic fishes and Arctic marine mammals represent key parts of this ecosystem, with fish being a common part of ice seal diets in the Arctic. Determining sizes of fish consumed by ice seals is difficult because otoliths are often the only part left of the fish after digestion. Otolith length is known to be positively related to fish length. By developing species-specific otolith-body morphometric relationships for Arctic marine fishes, fish length can be determined for fish prey found in seal stomachs. Fish were collected during ice free months in the Beaufort and Chukchi seas 2009 - 2014, and the most prevalent species captured were chosen for analysis. Otoliths from eleven fish species from seven families were measured. All species had strong linear relationships between otolith length and fish total length. Nine species had coefficient of determination values over 0.75, indicating that most of the variability in the otolith to fish length relationship was explained by the linear regression. These relationships will be applied to otoliths found in stomachs of three species of ice seals (spotted Phoca largha, ringed Pusa hispida, and bearded Erignathus barbatus) and used to estimate fish total length at time of consumption. Fish lengths can in turn be used to calculate fish weight, enabling further investigation into ice seal energetic demands. This application will aid in understanding how ice seals interact with fish communities in the US Arctic and directly contribute to diet comparisons among and within ice seal species. A better understanding of predator-prey interactions in the US Arctic will aid in predicting how ice seal and fish species will adapt to a changing Arctic.

    The utilisation of good design practices in the development of complex health services is essential to improving quality. Healthcare organisations, however, are often seriously out of step with modern design thinking and practice. As a starting point to encourage the uptake of good design practices, it is important to understand the context of their intended use. This study aims to do that by articulating current health service development practices. Eleven service development projects carried out in a large mental health service were investigated through in-depth interviews with six operation managers. The critical decision method in conjunction with diagrammatic elicitation was used to capture descriptions of these projects. Stage-gate design models were then formed to visually articulate, classify and characterise different service development practices. Projects were grouped into three categories according to design process patterns: new service introduction and service integration; service improvement; service closure. Three common design stages: problem exploration, idea generation and solution evaluation - were then compared across the design process patterns. Consistent across projects were a top-down, policy-driven approach to exploration, underexploited idea generation and implementation-based evaluation. This study provides insight into where and how good design practices can contribute to the improvement of current service development practices. Specifically, the following suggestions for future service development practices are made: genuine user needs analysis for exploration; divergent thinking and innovative culture for idea generation; and fail-safe evaluation prior to implementation. Better training for managers through partnership working with design experts and researchers could be beneficial.

    The penis is the reproductive organ that ensures efficient copulation and success of internal fertilization in all species of mammals, with special challenges for bats, where copulation can occur during flight. Comparative anatomical analyses of different species of bats can contribute to a better understanding of morphological diversity of this organ, concerning organization and function. In this study, we describe the external morphology and histomorphology of the penis and baculum in eleven species of molossid bats. The present study showed that penile organization in these species displayed the basic vascular mammalian pattern and had a similar pattern concerning the presence of the tissues constituting the penis, exhibiting three types of erectile tissue (the corpus cavernosum, accessory cavernous tissue, and corpus spongiosum) around the urethra. However, certain features varied among the species, demonstrating that most species are distinguishable by glans and baculum morphology and glans histological organization. Major variations in glans morphology were genus-specific, and the greatest similarities were shared by Eumops species and N. laticaudatus. The greatest interspecific similarities occurred between M. molossus and M. rufus and between Eumops species. Save for M. molossus and M. rufus, morphology of the baculum was species-specific; and in E. perotis, it did not occur in all specimens, indicating that it is probably under selection. In the histological organization, the most evident differences were number of septa and localization of the corpora cavernosa. In species with a baculum (Molossus, Eumops and Nyctinomops species), the corpora cavernosa predominantly occupied the dorsal region of the penile glans and is associated with the proximal (basal) portion of the baculum. In species that do not have a baculum (Cynomops, Molossops and Neoplatymops species), the corpora cavernosa predominantly occupied the ventro-lateral region of the glans

    Full Text Available Screening of household contacts of tuberculosis (TB patients is a recommended strategy to improve early case detection. While it has been widely implemented in low prevalence countries, the most optimal protocols for contact investigation in high prevalence, low resource settings is yet to be determined. This study evaluated contact investigation interventions in eleven lower and middle income countries and reviewed the association between context or program-related factors and the yield of cases among contacts.We reviewed data from nineteen first wave TB REACH funded projects piloting innovations to improve case detection. These nineteen had fulfilled the eligibility criteria: contact investigation implementation and complete data reporting. We performed a cross-sectional analysis of the percentage yield and case notifications for each project. Implementation strategies were delineated and the association between independent variables and yield was analyzed by fitting a random effects logistic regression.Overall, the nineteen interventions screened 139,052 household contacts, showing great heterogeneity in the percentage yield of microscopy confirmed cases (SS+, ranging from 0.1% to 6.2%. Compared to the most restrictive testing criteria (at least two weeks of cough the aOR's for lesser (any TB related symptom and least (all contacts restrictive testing criteria were 1.71 (95%CI 0.94-3.13 and 6.90 (95% CI 3.42-13.93 respectively. The aOR for inclusion of SS- and extra-pulmonary TB was 0.31 (95% CI 0.15-0.62 compared to restricting index cases to SS+ TB. Contact investigation contributed between <1% and 14% to all SS+ cases diagnosed in the intervention areas.This study confirms that high numbers of active TB cases can be identified through contact investigation in a variety of contexts. However, design and program implementation factors appear to influence the yield of contact investigation and its concomitant contribution to TB case detection.

    Total small-intestinal volvulus with malrotation (TSIVM) classically presents in the neonatal period; it occurs much less frequently in the adult and is often misdiagnosed. Prognosis is directly related to the degree and duration of intestinal ischemia. Our goal is to describe our experience with TSIVM in the adult, to identify any specific findings and to discuss its management. Eleven patients who had undergone surgery for TSIVM at three centers between 1992 and 2012 were included. Surgery was performed as an emergency for five patients and surgery was elective for six. Mean follow-up was 63 months (range: 12-270). Six patients had had previous abdominal surgery. In nine cases, the diagnosis of TSIVM was made preoperatively, mainly by CT scan in eight cases. Seven patients had associated congenital failure of retroperitoneal fixation of the right colon and all of these underwent a Ladd procedure. The mortality rate was zero. Of the five patients who underwent emergency surgery, three required intestinal resections, one of whom developed a short bowel syndrome. The six patients who underwent surgery electively had no surgical complications. TSIVM is a very unusual finding in adult patients. The diagnosis can be made by CT scan with IV and oral contrast, but it often comes to light only at the time of surgery, even though the patients have often had recurrent episodes of abdominal symptomatology that dated back to childhood. The Ladd procedure, consisting of division of Ladd's bands, widening of the mesentery, and incidental appendectomy, remains the standard surgical repair. Digestive surgeons who care for adults should be familiar with this procedure, and it should be performed, as often as possible, with the assistance of a pediatric surgeon. Copyright © 2016.

    Full Text Available Abstract Background Following the World Health Organization Forum in November 2007, the Beijing Declaration recognized the importance of food safety along with the rights of all individuals to a safe and adequate diet. The aim of this study is to retrospectively analyze the patterns in food alert and recall by countries to identify the principal hazard generators and gatekeepers of food safety in the eleven months leading up to the Declaration. Methods The food recall data set was collected by the Laboratory of the Government Chemist (LGC, UK over the period from January to November 2007. Statistics were computed with the focus reporting patterns by the 117 countries. The complexity of the recorded interrelations was depicted as a network constructed from structural properties contained in the data. The analysed network properties included degrees, weighted degrees, modularity and k-core decomposition. Network analyses of the reports, based on 'country making report' (detector and 'country reported on' (transgressor, revealed that the network is organized around a dominant core. Results Ten countries were reported for sixty per cent of all faulty products marketed, with the top 5 countries having received between 100 to 281 reports. Further analysis of the dominant core revealed that out of the top five transgressors three made no reports (in the order China > Turkey > Iran. The top ten detectors account for three quarters of reports with three > 300 (Italy: 406, Germany: 340, United Kingdom: 322. Conclusion Of the 117 countries studied, the vast majority of food reports are made by 10 countries, with EU countries predominating. The majority of the faulty foodstuffs originate in ten countries with four major producers making no reports. This pattern is very distant from that proposed by the Beijing Declaration which urges all countries to take responsibility for the provision of safe and adequate diets for their nationals.

    The main clinical, morphological, cytochemical, immunological features and therapy results of eleven patients diagnosed as acute myeloblastic leukemia M0 (AML-M0) are reported here. There were no clinical characteristics, abnormalities on physical examination or initial laboratory parameters that distinguished these eleven patients. Bone marrow aspirates were hypocellular in four patients. The leukemic cells were undifferentiated by light microscopy and myeloperoxidase (MPO) and/or Sudan Black B (SBB) stains were negative in all cases. Myeloid differentiation antigens were present on the leukemic cells of all eleven patients, whereas B and T cell markers were clearly negative except for CD4 and CD7 antigens. Whatever the treatment employed survival was very short. Eight of the eleven patients were treated and two achieved complete remission (CR) but only one of them is alive in continuous CR. Our results like those previously reported, suggest that AML-M0 patients have a very poor prognosis with standard induction therapies and should perhaps be considered for experimental therapeutic approaches.

    Full Text Available Kai Bai,* Qiucheng Cai,* Yi Jiang, Lizhi Lv Department of Hepatobiliary Surgery, Fuzong Clinical College, Fujian Medical University, Fuzhou, People’s Republic of China *These authors contributed equally to this work Abstract: Growing evidence has shown that coffee consumption is inversely related with the risk of hepatocellular carcinoma. It is suggested that caffeine maintains strong antioxidative activity. With this property, coffee intake may lead to the inhibition of cell proliferation of liver cancer cells; also, some compounds contained in coffee can reduce the genotoxicity of aflatoxin B1 in vitro and lower the damage caused by some carcinogens. A computerized search was performed in PubMed to identify relevant articles published before August 2015. Eleven relevant studies were included with a total of 2,795 cases and 340,749 control subjects. According to the meta-analysis we performed, the pooled odds ratio (OR from all included studies was 0.49 (95% confidence interval [CI] =0.46–0.52. The subgroup analysis indicated that the pooled ORs for Asian studies and other populations were 0.27 (95% CI =0.23–0.31 and 0.82 (95% CI =0.77–0.87, respectively. The overall pooled OR for high consumption was decreased to 0.21 (95% CI =0.18–0.25 and significance was observed. Among other populations, the pooled OR of subjects with high coffee consumption was 0.65 (95% CI =0.56–0.73 compared to the nondrinker. The corresponding OR of five Asian studies was 0.13 (95% CI =0.09–0.17. The findings from this meta-analysis further confirmed the inverse association between the coffee consumption and hepatocellular carcinoma risk with quantitative evidence. The protective effect can be detected among healthy population and patients with chronic liver diseases, and the consumption can also prevent the development of liver cirrhosis.

    Full Text Available Korpus er en type digitale språkressurser (maskinlesbare tekstsamlinger som er mye brukt i moderne lingvistikk som empirisk støtte for studiet av ulike språklige fenomener. Korpus kan med hell brukes i fremmedspråkundervisningen, men er frem til nå ikke i tilstrekkelig grad blitt tatt i bruk i norsk skole og høyere utdanning. I denne artikkelen gir vi en gjennomgang av eksisterende forskningslitteratur på feltet, med hovedvekt på bidrag fra det angloamerikanske språkområdet. Deretter går vi gjennom to korpus som er tilgjengelige for norske brukere, Norwegian-Spanish Parallel Corpus og Oslo Multilingual Corpus. Vi viser hvordan disse korpusene kan brukes i undervisningen av ulike språklige fenomener, fra vokabular til sosiolingvistiske fenomener. På grunnlag av eksisterende forskning på pedagogiske applikasjoner av korpus samt våre egne forslag til undervisningsopplegg er det grunn til å tro at bruk av korpus vil kunne være et verdifullt bidrag til fremmedspråkundervisningen i norske klasserom. Likevel finnes visse utfordringer som hindrer at korpus tas i bruk. Både mangel på tid, gruppestørrelser og teknologiske hindre kan stå i veien. Bruk av korpus i fremtidens klasserom er også nært knyttet til ulike trender, både innenfor teknologi og forskning. For det først blir datateknologi stadig mer tilgjengelig, parallelt med at elevenes og studentenes digitale kompetanse øker. Dette er fenomener som begge skulle tilsi økt bruk av korpus. Videre er det en sterk bevegelse for å åpne opp tilgang til forskningsdata og –ressurser (Open Access og denne bølgen kan også brukes til å åpne opp forskningsressurser, herunder korpus, for læringsformål. Til syvende og sist er spørsmålet om bruk av korpus i klasserommet imidlertid avhengig av en tettere dialog mellom lærere og korpuslingvister, både i lærerutdanningen så vel som gjennom faglig oppdatering underveis i yrkeslivet.

    Full Text Available The goal of this study was to evaluate the sensory profile of eleven peach cultivars grown in an experimental orchard located in the city of Lapa (PR, Brazil in two seasons. The peach cultivars analyzed were Aurora I, Chimarrita, Chiripá, Coral, Eldorado, Granada, Leonense, Maciel, Marli, Premier, and Vanguarda. The sensory analysis was performed by previously trained panelists; 20 of them in the first season and 10 in the second season. The sensory evaluation was performed using Quantitative Descriptive Analysis, in which the following attributes were measured: appearance, aroma, flesh color, flesh firmness, flavor, and juiciness. The results showed preference for sweet, soft, and juicy fruits. Chimarrita, Chiripá, and Coral fruits showed better sensorial performance than the other peach cultivars. It was also verified that the analysis of the attributes aroma, flesh firmness, and flavor is enough for performing the sensory profile of peach fruits for in natura consumption.Este trabalho teve como objetivo avaliar o perfil sensorial de onze cultivares de pêssego produzidos em duas safras em um pomar experimental implantado na Lapa (PR, Brasil.

    This study examined the relationships between perceived stress and a range of self reported symptoms and health complaints in a representative sample of students at one university in Egypt. The data (3,271 students) was collected during the academic year 2009-2010 at eleven faculties at the university of Assiut city, Egypt. A self-administered questionnaire measured health complaints (22 symptoms) and Cohen's Perceived Stress Scale. Socio-demographic and lifestyle data were also collected. Factor analysis generated four groups of health complaints: psychological, circulatory/breathing, gastrointestinal, and pains/aches, and the internal consistency of each group of symptoms was computed using reliability analyses (Cronbach's alpha). Perceived stress was categorized into four levels based on quartiles. Multiple binomial or multinomial logistic regression analyses analysed the relationship between each of the four groups of symptoms and other students' general characteristics adjusted for the effect of all other groups of symptoms. The symptoms most often reported as having occurred sometimes/very often in the last 12 months were fatigue (85.3%), difficulties to concentrate (78.1%), headache (77.9%), and mood swings (74.5%), while nervousness/anxiety (63.2%) and sleep disorder (63.7%) affected many students. Multinominal logistic regression revealed a clear association and a linear trend between increasing level of stress and a higher frequency of psychological symptoms that remained significant after adjustment for other groups of symptoms. There were no associations between perceived stress and circulatory/breathing symptoms, gastrointestinal symptoms, or for pains/aches. Poor health was consistently associated with higher frequency of symptoms across all symptom groups except for gastrointestinal symptoms. Higher health awareness was associated with lower frequency of psychological and circulatory/breathing symptoms but not for the other two symptom groups. Better

    This study records length-weight relationships (LWRs) for eleven commercially important marine catfish species of the family Ariidae (sea catfishes) and Plotosidae (eel catfishes) from the northern Arabian Sea coast of Pakistan. The specimens were sampled from December 2014 to November 2015, using bottom trawls with various mesh sizes by commercial vessels. The species were Nemapteryx caelatus, Sciades sona, Arius gagora, Batrachocephalus mino, Netuma thalassina, N. bilineata, Osteogeneiosus militaris, Plicofollis dussumieri, P. tenuispinis, Plotosus limbatus, and P. lineatus. Of the eleven species, two species A. gagora and N. bilineata were recorded for the first time and LWRs for four species A. gagora, N. bilineata, S. sona, and B. mino still have no data in the FishBase database. In addition, new maximum length for each of the three species N. bilineata, O. militaris and B. mino was also found.

  2. Elevated bark temperature in unremoved stumps after disturbances facilitates multi-voltinism in Ips typographus population in a mountainous forest

    2016-03-01

    Full Text Available The number of Ips typographus generations developed in a year might be indicative of its population size and of risk to Norway spruce forests. Warm weather and unremoved fallen trees after natural disturbances are thought of as key factors initiating large population increase. We studied I. typographus development in a spruce forest of the Tatra National Park, which was heavily affected by large-scale disturbances in the last decade. Repeated windthrows and consequent bark beetle outbreaks have damaged almost 20,000 hectares of mature Norway spruce forests, what is a half of the National Park forest area. Current I. typographus population size and its response to the environment and to forestry defense measures attract attention of all stakeholders involved in natural resource management, including public. In this paper we analyse the potential I. typographus population size in two consecutive years 2014 and 2015, which represented a climatologically normal year and an extremely hot year, respectively. We used bark temperature and phenology models to estimate the number of generations developed in each year. In 2014, the average bark temperature of standing living trees at study sites was 14.5 °C, in 2015 it increased to 15.7 °C. The bark temperature of fallen logs was 17.7 °C in 2014, and 19.5 °C in 2015. The bark temperature of standing living trees allowed to develop one and two generations in 2014 and 2015, respectively. The elevated bark temperature of fallen logs allowed to develop two generations in 2014 and three generations in 2015. The good match between the predicted and observed timing of each generation emergence as well as the large increase in the number of catches in pheromone traps in 2015 indicated a dramatic increase of the I. typographus population in the extremely warm year, especially at the unmanaged windthrown site.

The aim of this study was to investigate trends in participation, age, and performance in the longest inline race in Europe, the Inline One-Eleven over 111 km, held between 1998 and 2009.Methods: The total number, age distribution, age at the time of the competition, and race times of male and female finishers at the Inline One-Eleven were analyzed.Results: Overall participation increased until 2003 but decreased thereafter. During the 12-year period, the relative participation in skaters younger than 40 years old decreased while relative participation increased for skaters older than 40 years. The mean top ten skating time was 199 ± 9 minutes (range: 189–220 minutes for men and 234 ± 17 minutes (range: 211–271 minutes for women, respectively. The gender difference in performance remained stable at 17% ± 5% across years.Conclusion: To summarize, although the participation of master long-distance inline skaters increased, the overall participation decreased across years in the Inline One-Eleven. The race times of the best female and male skaters stabilized across years with a gender difference in performance of 17% ± 5%. Further studies should focus on the participation in the international World Inline Cup races.Keywords: endurance, men, women, gender

    Enterocolic lymphocytic phlebitis (ELP) is an uncommon cause of bowel pathology and most frequently results in ischaemia. It is characterised by an artery-sparing, venulocentric lymphoid infiltrate that causes a phlebitis and vascular compromise. Rare cases of ELP have been encountered with lymphocytic colitis in the absence of ischaemic bowel change. The present study examined the occurrence of ELP in the setting of diversion colitis and inflammatory bowel disease, as well as in random colectomy specimens. The study cohort comprised the following: 26 completion proctectomy specimens for ulcerative colitis with superimposed diversion colitis in the rectal stump; 3 colectomy specimens for Crohn disease with diversion colitis; 6 colectomy specimens for adenocarcinoma and/or diverticular disease with diversion colitis; 34 resection specimens with ulcerative colitis only; 19 with Crohn disease only; and 100 random colon resection specimens for adenocarcinoma, adenoma, diverticular disease and ischaemia. ELP was present in 18 of the 26 ulcerative colitis cases with diversion colitis, 3/3 Crohn disease cases with diversion colitis, 1/6 cases of diverticular disease with diversion colitis, 6/34 cases of ulcerative colitis without diversion, 2/19 Crohn disease cases without diversion colitis, and only 1 of 100 colectomy cases without inflammatory bowel disease or diversion colitis. ELP occurs most frequently in cases that have been diverted for inflammatory bowel disease. Fewer cases of ELP were noted in cases of inflammatory bowel disease in the absence of diversion colitis. It is postulated that altered bowel flora and immune dysregulation may be pivotal in the causation of this association.

    Postoperative pancreatic fistula (POPF) causes significant morbidity and mortality after distal pancreatectomy. Patch coverage of the pancreatic stump is often used with the intention to prevent POPF. Despite numerous investigations, the effects of patch coverage remain unclear. The present meta-analysis aims to clarify the effects of patch coverage in distal pancreatectomy on the incidence of POPF. A systematic search of MEDLINE/PubMed and the Cochrane Database according to the PRISMA Statement was performed. Subsequently a meta-analysis on rates and overall incidence of POPF and length of hospital stay was carried out. By applying the inverse variance weighting method, the combined effect size and 95 % confidence interval were calculated. Heterogeneity was assessed using I 2 statistics. Five randomized controlled trials and six observational clinical studies were included for final analysis. A cumulative incidence of 43 % of POPF grades A-C was identified. Patch coverage in distal pancreatectomy is significantly associated with a decreased rate of POPF grade C (p = 0.006). Patches of autologous vascularized tissue significantly reduce the overall incidence of POPF (p = 0.04) and clinically relevant POPF grade B and C (p = 0.002). Fibrin sealant patches do not influence rates of POPF after distal pancreatectomy. None of the outcomes evaluated showed adverse results for the patch group. Patch coverage after distal pancreatectomy can reduce the rate of POPF. Patch coverage with autologous vascularized tissue but not fibrin sealant patches may be used to reduce clinically relevant POPF and postoperative morbidity in distal pancreatectomy.

  8. The E-pistolary Novel: Print Screens of Media-driven Thoughts in David Llewellyn’s Eleven

    Full Text Available Contemporary literature seems to have reconciled the idea that everything valuable has already been said and done and, as such, has wilfully inscribed itself in a never-ending cycle of narratives about narratives, in a process of recycling and updating the past, which some love to name postmodernist. What is left at stake is simply the consumerist need to produce an oxymoronic ‘original copy’: to launch that piece of literature unseen and unheard of before on a crowded book market. A recipe for success seems to be the ability to combine the novelty of the architectural design – the formal innovation – with the thematisation of the present. It is precisely what the young Welsh novelist and scriptwriter, David Llewellyn, achieves with his debut novel, Eleven. In an attempt to translate the old into the new, Eleven is constructed following the design of the early modern epistolary novels, yet making use of a contemporary mode of writing: the email. Thematically, it is an exploration of patterns of individual thinking shaped by the media, against the background of an event with global consequences, which is, nevertheless, viewed from afar, without the inherent trauma so visible in American post-9/11 fiction. The present paper aims at analysing the construction of the novel, including the linguistic transformations it employs, and at accounting for the identitaryrevolt that transpires from the e mails exchanged between various character-narrators on an apparently ordinary day: September 11, 2001.

    For many years patients with chronic kidney disease have been advised to control the protein content of their diet. This advice has been given on the basis of a number of reported metabolic effects of lowering protein intake, such as lowering serum urea nitrogen levels, improving phosphocalcic metabolism and insulin resistance and, more recently, ameliorating proteinuria (independent of antiproteinuric medications). The effects on the progression of kidney disease, although spectacular in experimental studies, have been less convincing in humans. It is possible that flawed design of clinical trials is responsible for this discrepancy. In this Review, we comment on experimental findings that indicate that limiting protein intake protects the kidney and ameliorates uremic symptoms, outline how the body adapts to a reduction in protein intake, and describe the metabolic benefits to the patient. We then review the evidence from randomized controlled trials and meta-analyses that pertains to the effects of low-protein diets in adults with chronic kidney disease.

    Quality control of the magnetic resonance imagers of different vendors in the clinical environment is non-harmonised, and comparing the performance is difficult. The purpose of this study was to develop and apply a harmonised long-term quality control protocol for the six imagers in our organisation in order to assure that they fulfil the same basic image quality requirements. The same Eurospin phantom set and identical imaging parameters were used with each imager. Values of 11 comparable parameters describing the image quality were measured. Automatic image analysis software was developed to objectively analyse the images. The results proved that the imagers were operating at a performance level adequate for clinical imaging. Some deficiencies were detected in image uniformity and geometry. The automated analysis of the Eurospin phantom images was successful. The measurements were successfully repeated after 2 weeks on one imager and after half a year on all imagers. As an objective way of examining the image quality, this kind of comparable and objective quality control of different imagers is considered as an essential step towards harmonisation of the clinical MRI studies through a large hospital organisation.

    Sternal wound infection with Mycobacterium tuberculosis is an uncommon yet highly challenging disease that can be quite insidious with various presentations. We hereby provide a review of 10 cases in current literature and describe an additional case which illustrates the difficulties associated with diagnosis. We used PubMed and Google search engine to search the literature for all published papers reporting on cases of sternal M. tuberculosis infections post open-heart surgeries. A total of 11 cases were presented, including a case of our own. The majority were males and were exposed to endemic areas. The average age was 59.6 ± 15.5 years. Coronary artery bypass surgery accounted for 73% of procedures and the average time to symptoms onset was 12.2 ± 16.6 months. Diabetes was the most reported non-cardiac comorbidity. Presenting symptoms varied and only 5 patients had other organs involved. Blood tests and radiographic studies were neither sensitive nor specific. M. tuberculosis culture on debrided tissues was the most sensitive test but often forgotten initially. Diagnostic delay was seen in almost all cases, often leading to unnecessary courses of antibiotics and aggressive surgical interventions. Finally, all patients responded well to anti-tuberculosis treatment, with reported treatment duration ranging from 9 to 12 months. M. tuberculosis infection of the sternum should be suspected in late-onset sternal wound infections post open-heart surgery especially when the course is chronic and indolent.

To analyze eating behaviors, nutritional status and history of previous diseases, in students of higher education. Cross-sectional study in students of 54 higher education centers across the country. They answered a survey about dietary habits, physical activity, smoking, previous diseases and opinion of their nutritional condition. Weight and height were measured under standardized conditions and nutritional status classified according to body mass index. We studied 6,823 students aged 17 to 29 years. Forty seven percent did not have breakfast and 35% did not have lunch every day. A low proportion had a daily consumption of vegetables (51.2%), fruits (39.4%) and dairy products (57.5%). There was a high frequency of soft drinks, chips, cakes and sweets consumption. Seventy six percent were sedentary, 40.3% smokers and 27.4% overweight or obese. The latter had a significantly higher frequency of diabetes, hypertension and hypercholesterolemia. There was a poor agreement between actual nutritional status and self-perception, especially in males (Kappa index 0.38). Recipients of a food scholarship provided by the Ministry of Education ate lunch usually with a higher frequency (p food scholarship has some positive effects, although differences in socioeconomic levels limited comparisons.

    Full Text Available Seven species of amphibians and reptiles were observed in eleven Sites of Community Importance (SCI of the Lodi Province (NW Italy. Distribution and relative abundance of amphibians appeared more variable than reptiles. Some species of conservation concern as R. latastei were influenced by habitat physiognomy, i.e. the surface of wooded areas are important in predict presence and relative abundance of this species. SCI with wider surfaces and higher habitat heterogeneity included higher number of species. Species richness, here considered as a raw index of biodiversity value and community quality, was significantly related to SCI area and habitat heterogeneity; since this significant positive relation is confirmed both for amphibians and reptiles we suggest that, in planning of natural areas, priority must be retained for biotopes able to host the higher number of species.

    Eating out has been linked to the current obesity epidemic, but the evaluation of the extent to which out of home (OH) dietary intakes are different from those at home (AH) is limited. Data collected among 8849 men and 14,277 women aged 35-64 years from the general population of eleven European countries through 24-h dietary recalls or food diaries were analysed to: (1) compare food consumption OH to those AH; (2) describe the characteristics of substantial OH eaters, defined as those who consumed 25 % or more of their total daily energy intake at OH locations. Logistic regression models were fit to identify personal characteristics associated with eating out. In both sexes, beverages, sugar, desserts, sweet and savoury bakery products were consumed more OH than AH. In some countries, men reported higher intakes of fish OH than AH. Overall, substantial OH eating was more common among men, the younger and the more educated participants, but was weakly associated with total energy intake. The substantial OH eaters reported similar dietary intakes OH and AH. Individuals who were not identified as substantial OH eaters reported consuming proportionally higher quantities of sweet and savoury bakery products, soft drinks, juices and other non-alcoholic beverages OH than AH. The OH intakes were different from the AH ones, only among individuals who reported a relatively small contribution of OH eating to their daily intakes and this may partly explain the inconsistent findings relating eating out to the current obesity epidemic.

    Full Text Available Eleven Brazilian hexaploid triticale cultivars (2n = 6x = 42, from three breeding programs, were evaluated for theirability of self-fertilization in 2006 and for meiotic behavior, meiotic index and pollen viability at two sowing dates in 2007. Highpotential of self-fertilization was observed, with values up to 89.52 %. Many irregularities were found in the meiotic analysis, suchas the presence of univalents, laggard chromosomes and micronuclei in tetrads, which compromised both meiotic behavior andmeiotic index. At the first sowing date, more suitable for normal plant development, overall mean values of 52.68 % for normal cellsand 64.95 % for meiotic index were observed. At the second sowing date, less appropriate for the crop, overall means of 52.23 %for normal cells and 58.24 % for meiotic index were obtained. Despite all the irregularities, considerable pollen viability wasobserved, reaching overall means of 92.08 % and 91.07 % for the first and second sowing dates, respectively.

    The purpose of this study was to determine the failure mechanism of clinically failed Gates Glidden (GG) drills. Eleven retrieved GG drills (sizes #1 to #3) which fractured during root canal preparation were collected and the fracture location was recorded based on macroscopic observation. All fracture surfaces were investigated by a SEM. Then the fractured parts were embedded in acrylic resin and after metallographic preparation, the microstructure and elemental composition was evaluated by SEM and EDS. The Vickers hardness (HV) of all specimens was also determined. Macroscopic examination and SEM analysis showed that the drills failed near the hand piece end by torsional fatigue with fatigue cracks initiating at several locations around the circumference and propagating toward the center. Final fracture followed by a tensile overloading at the central region of cross section. Microstructural analysis, hardness measurements and EDS show that the drills are made of a martensitic stainless steel like AISI 440C. Based on the findings of this study, clinicians should expect fatigue fracture of GG drills that have small size during root canal preparation. Selection of a more fatigue resistant stainless steel alloy and enhancing the instrument design might reduce the incidence of quasi-cleavage fracture on GG drills.

    Dendrobium huoshanense (Orchidaceae) is a perennial herb and a widely used medicinal plant in Traditional Chinese medicine (TCM) endemic to Huoshan County town in Anhui province in Southeast China. A microsatellite-enriched genomic DNA library of D. huoshanense was developed and screened to identify marker loci. Eleven polymorphic loci were isolated and analyzed by screening 25 individuals collected from a natural population. The number of alleles per locus ranged from 2 to 5. The observed and expected heterozygosities ranged from 0.227 to 0.818 and from 0.317 to 0.757, respectively. Two loci showed significant deviations from Hardy-Weinberg equilibrium and four of the pairwise comparisons of loci revealed linkage disequilibrium (p < 0.05). These microsatellite loci were cross-amplified for five congeneric species and seven loci can be amplified in all species. These simple sequence repeats (SSR) markers are useful in genetic studies of D. huoshanense and other related species and in conservation decision-making. PMID:23222682

    Secondary compounds in fruit mediate interactions with natural enemies and seed dispersers, influencing plant survival and species distributions. The functions of secondary metabolites in plant defenses have been well-studied in green tissues, but not in reproductive structures of plants. In this study, the distribution of toxicity within plants was quantified and its influence on seed survival was determined in Central Panama. To investigate patterns of allocation to chemical defenses and shifts in allocation with fruit development, I quantified variation in toxicity between immature and mature fruit and between the seed and pericarp for eleven species. Toxicity of seed and pericarp was compared to leaf toxicity for five species. Toxicity was measured as reduced hyphal growth of two fungal pathogens, Phoma sp. and Fusarium sp., and reduced survivorship of brine shrimp, Artemia franciscana, across a range of concentrations of crude extract. I used these measures of potential toxicity against generalist natural enemies to examine the effect of fruit toxicity on reductions of fruit development and seed survival by vertebrates, invertebrates, and pathogens measured for seven species in a natural enemy removal experiment. The seed or pericarp of all vertebrate- and wind-dispersed species reduced Artemia survivorship and hyphal growth of Fusarium during the immature and mature stages. Only mature fruit of two vertebrate-dispersed species reduced hyphal growth of Phoma. Predispersal seed survival increased with toxicity of immature fruit to Artemia during germination and decreased with toxicity to fungi during fruit development. This study suggests that fruit toxicity against generalist natural enemies may be common in Central Panama. These results support the hypothesis that secondary metabolites in fruit have adaptive value and are important in the evolution of fruit-frugivore interactions.

    Police enrolled in the World Trade Center Health Registry (WTCHR) demonstrated increased probable posttraumatic stress disorder (PTSD) after the terrorist attack of 9/11/2001. Police enrollees without pre-9/11 PTSD were studied. Probable PTSD was assessed by Posttraumatic Stress Check List (PCL). Risk factors for chronic, new onset or resolved PTSD were assessed using multinomial logistic regression. Half of police with probable PTSD in 2003-2007 continued to have probable PTSD in 2011-2012. Women had higher prevalence of PTSD than men (15.5% vs. 10.3%, P = 0.008). Risk factors for chronic PTSD included decreased social support, unemployment, 2+ life stressors in last 12 months, 2+ life-threatening events since 9/11, 2+ injuries during the 9/11 attacks, and unmet mental health needs. Police responders to the WTC attacks continue to bear a high mental health burden. Improved early access to mental health treatment for police exposed to disasters may be needed. © 2015 Wiley Periodicals, Inc.

    Previous research investigating the relationship between parents' and children's diets has focused on single foods or nutrients, and not on global diet, which may be more important for good health. The aim of the study was to investigate the relationship between parental diet quality and child dietary patterns. A cross-sectional survey was conducted in 17 primary schools in Dunedin, New Zealand. Information on food consumption and related factors in children and their primary caregiver/parent were collected. Principal component analysis (PCA) was used to investigate dietary patterns in children and diet quality index (DQI) scores were calculated in parents. Relationships between parental DQI and child dietary patterns were examined in 401 child-parent pairs using mixed regression models. PCA generated two patterns; 'Fruit and Vegetables' and 'Snacks'. A one unit higher parental DQI score was associated with a 0.03SD (CI: 0.02, 0.04) lower child 'Snacks' score. There was no significant relationship between 'Fruit and Vegetables' score and parental diet quality. Higher parental diet quality was associated with a lower dietary pattern score in children that was characterised by a lower consumption frequency of confectionery, chocolate, cakes, biscuits and savoury snacks. These results highlight the importance of parental modelling, in terms of their dietary choices, on the diet of children.

    This study was designed to provide typical descriptive statistics, score distributions and percentile ranks of the Jefferson Scale of Empathy-Medical Student version (JSE-S) of male and female medical school matriculants to serve as proxy norm data and tentative cutoff scores. The participants were 2,637 students (1,336 women and 1,301 men) who matriculated at Sidney Kimmel (formerly Jefferson) Medical College between 2002 and 2012, and completed the JSE at the beginning of medical school. Information extracted from descriptive statistics, score distributions and percentile ranks for male and female matriculants were used to develop proxy norm data and tentative cutoff scores. The score distributions of the JSE tended to be moderately skewed and platykurtic. Women obtained a significantly higher mean score (116.2 ± 9.7) than men (112.3 ± 10.8) on the JSE-S (t2,635 = 9.9, p norm data. The tentative cutoff score to identify low scorers was ≤ 95 for men and ≤ 100 for women.

    Full Text Available Previous research investigating the relationship between parents’ and children’s diets has focused on single foods or nutrients, and not on global diet, which may be more important for good health. The aim of the study was to investigate the relationship between parental diet quality and child dietary patterns. A cross-sectional survey was conducted in 17 primary schools in Dunedin, New Zealand. Information on food consumption and related factors in children and their primary caregiver/parent were collected. Principal component analysis (PCA was used to investigate dietary patterns in children and diet quality index (DQI scores were calculated in parents. Relationships between parental DQI and child dietary patterns were examined in 401 child-parent pairs using mixed regression models. PCA generated two patterns; ‘Fruit and Vegetables’ and ‘Snacks’. A one unit higher parental DQI score was associated with a 0.03SD (CI: 0.02, 0.04 lower child ‘Snacks’ score. There was no significant relationship between ‘Fruit and Vegetables’ score and parental diet quality. Higher parental diet quality was associated with a lower dietary pattern score in children that was characterised by a lower consumption frequency of confectionery, chocolate, cakes, biscuits and savoury snacks. These results highlight the importance of parental modelling, in terms of their dietary choices, on the diet of children.

    Full Text Available Abstract Background In cancer cells the three-dimensional (3D telomere organization of interphase nuclei into a telomeric disk is heavily distorted and aggregates are found. In Hodgkin's lymphoma quantitative FISH (3D Q-FISH reveals a major impact of nuclear telomere dynamics during the transition form mononuclear Hodgkin (H to diagnostic multinuclear Reed-Sternberg (RS cells. In vitro and in vivo formation of RS-cells is associated with the increase of very short telomeres including "t-stumps", telomere loss, telomeric aggregate formation and the generation of "ghost nuclei". Results Here we analyze the 3D telomere dynamics by Q-FISH in the novel Hodgkin cell line U-HO1 and its non-receptor protein-tyrosine phosphatase N1 (PTPN1 stable transfectant U-HO1-PTPN1, derived from a primary refractory Hodgkin's lymphoma. Both cell lines show equally high telomerase activity but U-HO1-PTPN differs from U-HO1 by a three times longer doubling time, low STAT5A expression, accumulation of RS-cells (p As expected, multinuclear U-HO1-RS-cells and multinuclear U-HO1-PTPN1-RS-cells differ from their mononuclear H-precursors by their nuclear volume (p Conclusion Abundant RS-cells without additional very short telomeres including "t-stumps", high rate of apoptosis, but low STAT5A expression, are hallmarks of the U-HO1-PTPN1 cell line. These characteristics are independent of telomerase activity. Thus, PTPN1 induced dephosphorylation of STAT5 with consecutive lack of Akt/PKB activation and cellular arrest in G2, promoting induction of apoptosis, appears as a possible pathogenetic mechanism deserving further experimental investigation.

    Gossypium anomalum (BB genome) possesses the desirable characteristics of drought tolerance, resistance to diseases and insect pests, and the potential for high quality fibers. However, it is difficult to transfer the genes associated with these desirable traits into cultivated cotton (G. hirsutum, AADD genome). Monosomic alien addition lines (MAALs) can be used as a bridge to transfer desired genes from wild species into G. hirsutum. In cotton, however, the high number and smaller size of the chromosomes has resulted in difficulties in discriminating chromosomes from wild species in cultivated cotton background, the development of cotton MAALs has lagged far behind many other crops. To date, no set of G. hirsutum-G. anomalum MAALs was reported. Here the amphiploid (AADDBB genome) derived from G. hirsutum × G. anomalum was used to generate a set of G. hirsutum-G. anomalum MAALs through a combination of consecutive backcrossing, genomic in situ hybridization (GISH), morphological survey and microsatellite marker identification. We improved the GISH technique used in our previous research by using a mixture of two probes from G. anomalum and G. herbaceum (AA genome). The results indicate that a ratio of 4:3 (G. anomalum : G. herbaceum) is the most suitable for discrimination of chromosomes from G. anomalum and the At-subgenome of G. hirsutum. Using this improved GISH technique, 108 MAAL individuals were isolated. Next, 170 G. hirsutum- and G. anomalum-specific codominant markers were obtained and employed for characterization of these MAAL individuals. Finally, eleven out of 13 MAALs were identified. Unfortunately, we were unable to isolate Chrs. 1B a and 5B a due to their very low incidences in backcrossing generation, as these remained in a condition of multiple additions. The characterized lines can be employed as bridges for the transfer of desired genes from G. anomalum into G. hirsutum, as well as for gene assignment, isolation of chromosome

    Paleoecological data provide estimates of response rates to past climate changes. Fossil Pinus sylvestris stumps in far northern Scotland demonstrate former presence of pine trees where conventional pollen evidence of pine forests is lacking. Radiocarbon, dendrochronological, and fine temporal-resolution palynological data show that pine forest were present for about four centuries some 4,000 years ago; the forests expanded and then retreated rapidly some 70 to 80 kilometers. Despite the rapidity of this response to climate change, it occurred at rates slower by an order of magnitude than those necessary to maintain equilibrium with forecast climate changes attributed to the greenhouse effect

    A pancreatic fistula is one of the most serious complications in distal pancreatectomy with en bloc celiac axis resection (DP-CAR), because the pancreatic transection is performed on the right side of the portal vein, which results in a large cross-section surface, and because post-pancreatectomy hemorrhage is hard to treat by interventional radiology. Therefore, a procedure to decrease the incidence of postoperative pancreatic fistula is urgently needed. Twenty-six consecutive patients who underwent DP-CAR between April 2008 and August 2012 were reviewed retrospectively. The first 13 consecutive patients underwent DP-CAR with no anastomosis, and the subsequent 13 consecutive patients were treated with Roux-en-Y pancreaticojejunostomy (PJ) in a duct-to-mucosa fashion. Extremely high amylase levels (>4000 IU/l) of all drainage fluid specimens on postoperative day (POD) 1, 3 and 4 were detected more frequently in cases with no anastomosis (n = 7) compared to those with PJ (n = 1) (P = 0.056). The incidence of grade B/C pancreatic fistulas was 15.4% in cases with isolated Roux-en-Y anastomosis of the pancreatic stump performed in a duct-to-mucosa fashion, and we are currently examining whether this anastomosis method reduces the pancreatic fistula rate in a multicenter, randomized controlled trial for distal pancreatectomy patients (ClinicalTrials.gov NCT01384617). © 2013 Japanese Society of Hepato-Biliary-Pancreatic Surgery.

    A new Lagrangian realizing the symmetry of the M-algebra in eleven-dimensional space-time is presented. By means of the novel technique of Abelian semigroup expansion, a link between the M-algebra and the orthosymplectic algebra osp(32 vertical stroke 1) is established, and an M-algebra-invariant symmetric tensor of rank six is computed. This symmetric invariant tensor is a key ingredient in the construction of the new Lagrangian. The gauge-invariant Lagrangian is displayed in an explicitly Lorentz-invariant way by means of a subspace separation method based on the extended Cartan homotopy formula. (orig.)

    Full Text Available De norske PISA-resultatene i 2015 viste en framgang i lesing for norske 15-åringer, men andelen elever på det laveste nivået var fortsatt uendret. Denne artikkelen studerer de norske elevene i denne kategorien når det gjelder hvilke tekst- og oppgavetyper de har særlige problemer med og hva som kjennetegner deres lesevaner og kunnskap om lesestrategier. Datagrunnlaget stammer i hovedsak fra PISA 2009, da lesing hadde hovedfokus. Resultatene viser at de svakeste leserne relativt sett har størst problemer med komplekse fagtekster og minst problemer med skjønnlitterære tekster, og at de mangler kunnskap om lesestrategier. Samtidig er de mer interessert i å lese aviser og nettbaserte tekster enn skjønnlitteratur. Vi peker på elevenes leseinteresser, samt viktigheten av å arbeide med leseforståelse i alle fag, også i videregående skole, som utgangspunkt for å bidra til å redusere andelen svake lesere.

    Eleven obligate or facultative anaerobe strains were seeded successively in the alimentary tracts of 'gnotoxenic' mice. The animals were divided into four groups which received a commercially available diet sterilized by autoclaving or by irradiation (4Mrad) or treated with the two methods in succession and supplemented or not supplemented in vitamins. A series of quantitative differential analyses carried out over a period of seven months on the faeces of the animals did not reveal any significant differences in the equilibrium that became established among the eleven strains in the faecal flora of the four groups of animals. At the end of the experiment quantitative differential analyses were performed of the stomachal and caecal flora of two animals from each group; again no differences were found in the equilibrium of the flora in the animals from the different groups. Any radiolytic products that may have been in the radiation-sterilized diet therefore had no detectable effect on the equilibrium of the microflora that the authors had chosen to establish in the alimentary tract of the 'gnotoxenic' animals.

    Each year over five million people develop chronic non-malignant pain and can experience healthcare as an adversarial struggle. The aims of this study were: (1) to bring together qualitative evidence syntheses that explore patients' experience of living with chronic non-malignant pain and develop conceptual understanding of what it is like to live with chronic non-malignant pain for improved healthcare; (2) to undertake the first mega-ethnography of qualitative evidence syntheses using the methods of meta-ethnography. We used the seven stages of meta-ethnography refined for large studies. The innovation of mega-ethnography is to use conceptual findings from qualitative evidence syntheses as primary data. We searched 7 bibliographic databases from inception until February 2016 to identify qualitative evidence syntheses that explored patients' experience of living with chronic non-malignant pain. We identified 82 potential studies from 556 titles, screened 34 full text articles and included 11 qualitative evidence syntheses synthesising a total of 187 qualitative studies reporting more than 5000 international participants living with chronic pain. We abstracted concepts into 7 conceptual categories: (1) my life is impoverished and confined; (2) struggling against my body to be me; (3) the quest for the diagnostic 'holy grail'; (4) lost personal credibility; (5) trying to keep up appearances; (6) need to be treated with dignity; and (7) deciding to end the quest for the grail is not easy. Each conceptual category was supported by at least 7 of the 11 qualitative evidence syntheses. This is the first mega-ethnography, or synthesis of qualitative evidence syntheses using the methods of meta-ethnography. Findings help us to understand that the decision to end the quest for a diagnosis can leave patients feeling vulnerable and this may contribute to the adversarial nature of the clinical encounter. This knowledge demonstrates that treating a patient with a sense that they

    Full Text Available Polarized (POL training intensity distribution (TID emphasizes high-volume low-intensity exercise in zone (Z1 (< first lactate threshold with a greater proportion of high-intensity Z3 (>second lactate threshold compared to Z2 (between first and second lactate threshold. In highly trained rowers there is a lack of prospective controlled evidence whether POL is superior to pyramidal (PYR; i.e., greater volume in Z1 vs. Z2 vs. Z3 TID. The aim of the study was to compare the effect of POL vs. PYR TID in rowers during an 11-wk preparation period. Fourteen national elite male rowers participated (age: 20 ± 2 years, maximal oxygen uptake (V˙O2max: 66 ± 5 mL/min/kg. The sample was split into PYR and POL by varying the percentage spent in Z2 and Z3 while Z1 was clamped to ~93% and matched for total and rowing volume. Actual TIDs were based on time within heart rate zones (Z1 and Z2 and duration of Z3-intervals. The main outcome variables were average power in 2,000 m ergometer-test (P2,000 m, power associated with 4 mmol/L [blood lactate] (P4[BLa], and V˙O2max. To quantify the level of polarization, we calculated a Polarization-Index as log (%Z1 × %Z3 / %Z2. PYR and POL did not significantly differ regarding rowing or total volume, but POL had a higher percentage of Z3 intensities (6 ± 3 vs. 2 ± 1%; p < 0.005 while Z2 was lower (1 ± 1 vs. 3 ± 2%; p < 0.05 and Z1 was similar (94 ± 3 vs. 93 ± 2%, p = 0.37. Consequently, Polarization-Index was significantly higher in POL (3.0 ± 0.7 vs. 1.9 ± 0.4 a.u.; p < 0.01. P2,000 m did not significantly change with PYR (1.5 ± 1.7%, p = 0.06 nor POL (1.5 ± 2.6%, p = 0.26. V˙O2max did not change (1.7 ± 5.6%, p = 0.52 or 0.6 ± 2.6, p = 0.67 and a small increase in P4[BLa] was observed in PYR only (1.9 ± 4.8%, p = 0.37 or −0.5 ± 4.1%, p = 0.77. Changes from pre to post were not significantly different between groups in any performance measure. POL did not prove to be superior to PYR, possibly due to

    Do the socio-demographic and fertility-related characteristics and motivations of oocyte donors differ in European countries? The socio-demographic and fertility-related characteristics and motivations of oocyte donors differ considerably across countries. There have been no other international studies comparing the characteristics of oocyte donors. Regarding their motivations, most studies indicate mixed motives. The proposed study was a transversal epidemiological study. Data were collected from 63 voluntarily participating assisted reproduction technology centres practising oocyte donation in 11 European countries (Belgium, Czech Republic, Finland, France, Greece, Poland, Portugal, Russia, Spain, UK and Ukraine). The survey was conducted between September 2011 and June 2012 and ran for 1-6 calendar months depending on the number of cycles of oocyte donation performed at the centre. The sample size was computed in order to allow an estimate of the percentage of a relatively rare characteristic (∼2%) with a precision (95% confidence interval) of 1%. The calculation gave 1118 donors. In total, 1423 forms were obtained from oocyte donors. All consecutive donors in these centres filled out an anonymous questionnaire when they started their hormonal stimulation, asking for their socio-demographic and fertility-related characteristics, their motivations and compensation. Population characteristics were described and compared by country of donation. Motives for donation and mean amount of money were compared between countries and according to the donors characteristics. The socio-demographic and fertility-related characteristics and motivations of oocyte donors varied enormously across European countries. The number of received forms corresponded with a participation rate of 61.9% of the cycles performed by the participating centres. Mean age was 27.4 years. About 49% of donors were fully employed, 16% unemployed and 15% student. The motivation in the total group of

    In the last two decades, thyroglobulin autoantibodies (TgAb) measurement has progressively switched from marker of thyroid autoimmunity to test associated with thyroglobulin (Tg) to verify the presence or absence of TgAb interference in the follow-up of patients with differentiated thyroid cancer. Of note, TgAb measurement is cumbersome: despite standardization against the International Reference Preparation MRC 65/93, several studies demonstrated high inter-method variability and wide variation in limits of detection and in reference intervals. Taking into account the above considerations, the main aim of the present study was the determination of TgAb upper reference limit (URL), according to the National Academy of Clinical Biochemistry guidelines, through the comparison of eleven commercial automated immunoassay platforms. The sera of 120 healthy males, selected from a population survey in the province of Verona, Italy, were tested for TgAb concentration using eleven IMA applied on as many automated analyzers: AIA-2000 (AIA) and AIA-CL2400 (CL2), Tosoh Bioscience; Architect (ARC), Abbott Diagnostics; Advia Centaur XP (CEN) and Immulite 2000 XPi (IMM), Siemens Healthineers; Cobas 6000 (COB), Roche Diagnostics; Kryptor (KRY), Thermo Fisher Scientific BRAHMS, Liaison XL (LIA), Diasorin; Lumipulse G (LUM), Fujirebio; Maglumi 2000 Plus (MAG), Snibe and Phadia 250 (PHA), Phadia AB, Thermo Fisher Scientific.

Since TgAb values were not normally distributed, the experimental URL (e-URL) was established at 97.5 percentile according to the non-parametric method. TgAb e-URLs showed a significant inter-method variability. Considering the same method, e-URL was much lower than that suggested by manufacturers (m

    This map covers the drainage basins of the upper Current River and the Eleven Point River in the Ozark Plateaus physiographic province of southeastern Missouri. The two surface drainage basins are contiguous in their headwaters regions, but are separated in their lower reaches by the lower Black River basin in the southeast corner of the map area. Numerous dye-trace studies demonstrate that in the contiguous headwaters areas, groundwater flows from the Eleven Point River basin into the Current River basin. Much of the groundwater discharge of the Eleven Point River basin emanates from Big Spring, located on the Current River. This geologic map and cross sections were produced to help fulfill a need to understand the geologic framework of the region in which this subsurface flow occurs.

    In the present study, 11 4,4'-diaminostilbene-2,2'-disulfonic acid based fluorescent whitening agents with different numbers of sulfonic acid groups were separated by using an ionic liquid as a mobile phase additive in high-performance liquid chromatography with fluorescence detection. The effects of ionic liquid concentration, pH of mobile phase B, and composition of mobile phase A on the separation of fluorescent whitening agents were systematically investigated. The ionic liquid tetrabutylammonium tetrafluoroborate is superior to tetrabutylammomnium bromide for the separation of the fluorescent whitening agents. The optimal separation conditions were an ionic liquid concentration at 8 mM and the pH of mobile phase B at 8.5 with methanol as mobile phase A. The established method exhibited low limits of detection (0.04-0.07 ng/mL) and wide linearity ranges (0.30-20 ng/mL) with high linear correlation coefficients from 0.9994 to 0.9998. The optimized procedure was applied to analyze target analytes in paper samples with satisfactory results. Eleven target analytes were quantified, and the recoveries of spiked paper samples were in the range of 85-105% with the relative standard deviations from 2.1 to 5.1%. The obtained results indicated that the method was efficient for detection of 11 fluorescent whitening agents. © 2016 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

    One of the major functions of DNA methylation is the repression of transposable elements, such as the long-interspersed nuclear element 1 (L1). The underlying mechanism(s), however, are unclear. Here, we addressed how retrotransposon activation and mobilization are regulated by methyl-cytosine modifying ten-eleven-translocation (Tet) proteins and how this is modulated by methyl-CpG binding domain (MBD) proteins. We show that Tet1 activates both, endogenous and engineered L1 retrotransposons. Furthermore, we found that Mecp2 and Mbd2 repress Tet1-mediated activation of L1 by preventing 5hmC formation at the L1 promoter. Finally, we demonstrate that the methyl-CpG binding domain, as well as the adjacent non-sequence specific DNA binding domain of Mecp2 are each sufficient to mediate repression of Tet1-induced L1 mobilization. Our study reveals a mechanism how L1 elements get activated in the absence of Mecp2 and suggests that Tet1 may contribute to Mecp2/Mbd2-deficiency phenotypes, such as the Rett syndrome. We propose that the balance between methylation "reader" and "eraser/writer" controls L1 retrotransposition.

    Full Text Available Immediate treatment with an automated external defibrillator (AED increases out-of-hospital cardiac arrest (OHCA patient survival potential. While considerable attention has been given to determining optimal public AED locations, spatial and temporal factors such as time of day and distance from emergency medical services (EMSs are understudied. Here we describe a geocomputational genetic algorithm with a new stirring operator (GANSO that considers spatial and temporal cardiac arrest occurrence factors when assessing the feasibility of using Taipei 7-Eleven stores as installation locations for AEDs. Our model is based on two AED conveyance modes, walking/running and driving, involving service distances of 100 and 300 meters, respectively. Our results suggest different AED allocation strategies involving convenience stores in urban settings. In commercial areas, such installations can compensate for temporal gaps in EMS locations when responding to nighttime OHCA incidents. In residential areas, store installations can compensate for long distances from fire stations, where AEDs are currently held in Taipei.

    Recently, hydroxylated polybrominated diphenyl ethers (OH-PBDEs) have emerged as environmentally relevant pollutants due to recent reports of their natural production and metabolism. Recent mechanistic studies in human and rats have shown that some OH-PBDEs are more potent than parent compounds (PBDEs) and may contribute substantially to neurodevelopmental disorders by direct neurotoxicity, or indirectly through altered thyroid disruption. However, analytical methodologies for determination of OH-PBDEs are currently limited. In this study a robust liquid chromatography-electrospray tandem triple quadrupole-linear ion trap mass spectrometer (LC-ESI-QqLIT-MS-MS) in negative mode method was developed for the determination of eleven OH-tri- to OH-hexa-PBDEs. Two different columns were tested and compared for chromatographic separation: a C18 BetaBasic and a Purospher STAR RP 18, working at pH 8 and 10, respectively. Mobile phase (acetonitrile:water) was optimized by changing the pH of the aqueous phase and the concentration of the organic modifier (methanol). The MS-MS parameters (declustering potential (DP), collision energy (CE) and cell exit potential (CXP)) were optimized. Selected reaction monitoring (SRM) was used in order to increase sensitivity. Two SRM transitions ([M-H](-)>[Br](-)) were selected for each OH-PBDE, one for quantification and the second one for confirmation. Under the optimized conditions, the instrumental limits of detection were between 0.17 and 0.72injectedpg. The method provided good linearity (r>0.99 for a concentration range of 0.30-100ng/mL), accuracy and precision (%Dev and %RSD≤20% for intra- and inter-assays). Copyright © 2013 Elsevier B.V.

    Dental pulp inflammation is a bacterially driven inflammation process characterized by the local accumulation of cytokines/chemokines that participate in destructive processes in the pulp. Multiple mechanisms are involved in dental pulp inflammation, including epigenetic events, such as DNA methylation/demethylation. Ten-eleven translocation 2 (TET2) is a recently discovered DNA methylcytosine dioxygenase that plays important roles in inflammatory disease. However, its role in the inflammatory response of dental pulp is unknown. We observed elevated mRNA and protein levels of TET2 after lipopolysaccharide (LPS) stimulation in human dental pulp cells (hDPCs). To identify the effects of TET2 on cytokine expression, TET2 was knocked down and cytokines were detected using a cytokine antibody array after LPS stimulation. The protein expression of GM-CSF, IL-6, IL-8 and RANTES decreased in the LPS-induced hDPCs following TET2 knockdown. The downregulated expression levels of IL-6 and IL-8 were further confirmed by real-time quantitative polymerase chain reaction (qRT-PCR) and enzyme-linked immunosorbent assay (ELISA). Additionally, the phosphorylation levels of IKK-α/β, p65 and IκBα of the NF-κB signaling pathway were decreased in the TET2-silenced group. Furthermore, the global 5-hydroxymethylcytosine (5hmC) level was significantly decreased and the genomic 5-methylcytosine (5mC) level was increased in the TET2-deficient hDPCs; TET2 depletion resulted in a decrease in the 5hmC level of the MyD88 promoter following LPS stimulation. These findings indicate that TET2 knockdown inhibits LPS-induced inflammatory response in hDPCs by downregulating MyD88 hydroxymethylation. Thus, TET2-dependent DNA demethylation might play an important role in dental pulp inflammation as an epigenetic regulator.

    Extracapsular spread (ECS) is an important prognostic factor for oral squamous cell carcinoma (OSCC) and is used to guide management. In this study, we aimed to identify an expression profile signature for ECS in node-positive OSCC using data derived from two different sources: a cohort of OSCC patients from our institution (National Cancer Centre Singapore) and The Cancer Genome Atlas (TCGA) head and neck squamous cell carcinoma (HNSCC) cohort. We also sought to determine if this signature could serve as a prognostic factor in node negative cancers. Patients with a histological diagnosis of OSCC were identified from an institutional database and fresh tumor samples were retrieved. RNA was extracted and gene expression profiling was performed using the Affymetrix GeneChip Human Genome U133 Plus 2.0 microarray platform. RNA sequence data and corresponding clinical data for the TCGA HNSCC cohort were downloaded from the TCGA Data Portal. All data analyses were conducted using R package and SPSS. We identified an 11 gene signature (GGH, MTFR1, CDKN3, PSRC1, SMIM3, CA9, IRX4, CPA3, ZSCAN16, CBX7 and ZFP3) which was robust in segregating tumors by ECS status. In node negative patients, patients harboring this ECS signature had a significantly worse overall survival (p=0.04). An eleven gene signature for ECS was derived. Our results also suggest that this signature is prognostic in a separate subset of patients with no nodal metastasis Further validation of this signature on other datasets and immunohistochemical studies are required to establish utility of this signature in stratifying early stage OSCC patients.

  18. Aerial radiological and photographic survey of eleven atolls and two islands within the Northern Marshall Islands. Dates of surveys, July-November 1978

    International Nuclear Information System (INIS)

    An aerial radiological survey was conducted over eleven atolls and two islands within the northern Marshall Islands between September and November 1978. This survey was part of a comprehensive radiological survey, which included extensive terrestrial and marine sampling, to determine possible residual contamination which might remain as a result of the United States nuclear testing program conducted at Bikini Enewetak Atolls between 1946 and 1958. A similar survey was conducted at Enewetak Atoll in 1972. The present survey covered those atolls known to have received direct fallout from the Bravo event, conducted in March 1954 at Bikini Atoll. These included Bikini, Rongelap, Rongerik, Ailinginae, Bikar, Taka, and Utirik Atolls. In addition, several atolls and islands which might have been at the fringes of the Bravo fallout were also surveyed, including Likiep and Ailuk Atolls, Jemo and Mejit Islands, and Wotho Atoll. Ujelang Atoll, which lies approximately 200 km southwest of Enewetak, was also surveyed. Island-averaged terrestrial exposure rates in the range of 30 to 50 μR/h were observed over parts of Bikini Atoll, including Bikini Island, and over the northern part of Rongelap Atoll. Levels over southern Rongelap and over Rongerik Atoll ranged from 4 to 7 μR/h. Levels were somewhat lower at Ailinginae Atoll (approximately 2 μR/h) and at Utirik Atoll (approximately 0.7 μR/h). The variations observed were consistent with what might be expected from the fallout pattern of the Bravo event. Levels at Ailuk, Likiep, Wotho and Ujelang Atolls and at Mejit and Jemo Islands were consistent with 137 Cs activity, due to worldwide fallout, observed within the United States and at other locations in the central Pacific. These four atolls and the two islands, therefore, do not appear to have recieved any significant direct contamination from the Bravo event or the other tests conducted at Bikini and Enewetak Atolls

    Full Text Available Storage of potato tubers at low temperature affects their metabolism and may alter their phytochemical properties. There is a need to elucidate the changes in antioxidant compounds, activity and enzymes during storage of tubers. Eleven Indian potato varieties were evaluated for antioxidant parameters, after 0, 30, 60 and 90 days of storage at room temperature, 15 °C and 4 °C. Total phenolics (0.0786–0.1546 mg gallic acid equivalents⋅g−1 FW and vitamin C content (0.0828–0.2416 mg⋅g−1 FW varied among the varieties and were different with storage temperature; their levels fluctuated during storage but remained above the initial level until the last day of observation. Phenolic acid profiling by UPLC identified 12 compounds among which the most abundant was chlorogenic acid followed by gallic acid, sinapic acid and ellagic acid. Except para-coumaric acid which decreased at 4 °C, all the phenolic acids increased with storage. Caffeic acid, chlorogenic acid, protocatechuic acid and gallic acid mostly correlated with total phenolic content (r = 0.456, 0.482, 0.588 and 0.620, respectively. Antioxidant activity against both DPPH and ABTS radicals increased during the initial days of storage and then dropped to a level comparable or lower than the original value, irrespective of the storage temperature. Correlation study revealed that chlorogenic acid, gallic acid and ferulic acid mostly contributed to antioxidant activity. Activity of both antioxidant enzymes, superoxide dismutase and ascorbate peroxidase, increased initially but then decreased to values lower than the initial level and were not influenced by storage temperature. Correlation with antioxidant activity indicated that the enhancement of reactive oxygen scavenging species in cold stored tubers could result mainly from ascorbate peroxidase activity. Our results demonstrate that storage temperature adversely influences the metabolism and the content of

    Accumulating evidence indicates that microRNAs are able to act as oncogenes or tumor suppressor genes in human cancer. We previously reported that miR-520b was down-regulated in hepatocellular carcinoma (HCC) and its deregulation was involved in hepatocarcinogenesis. In the present study, we report that miR-520b suppresses cell proliferation in HCC through targeting the ten-eleven translocation 1 (TET1) mRNA. Notably, we identified that miR-520b was able to target 3′-untranslated region (3′UTR) of TET1 mRNA by luciferase reporter gene assays. Then, we revealed that miR-520b was able to reduce the expression of TET1 at the levels of mRNA and protein using reverse transcription-polymerase chain reaction and Western blotting analysis. In terms of function, 5-ethynyl-2-deoxyuridine (EdU) incorporation and colony formation assays demonstrated that the forced miR-520b expression remarkably inhibited proliferation of hepatoma cells, but TET1 overexpression could rescue the inhibition of cell proliferation mediated by miR-520b. Furthermore, anti-miR-520b enhanced proliferation of hepatoma cells, whereas silencing of TET1 abolished anti-miR-520b-induced acceleration of cell proliferation. Then, we validated that the expression levels of miR-520b were negatively related to those of TET1 mRNA in clinical HCC tissues. Thus, we conclude that miR-520b depresses proliferation of liver cancer cells through targeting 3′UTR of TET1 mRNA. Our finding provides new insights into the mechanism of hepatocarcinogenesis. - Highlights: • TET1 is a novel target gene of miR-520b. • TET1 is upregulated in clinical HCC tissues. • MiR-520b is negatively correlated with TET1 in clinical HCC tissues. • MiR-520b depresses the proliferation of HCC cells through targeting TET1 mRNA.

    It is now commonly accepted that there exists a form of drug supply, that involves the non-commercial supply of drugs to friends and acquaintances for little or no profit, which is qualitatively different from profit motivated 'drug dealing proper'. 'Social supply', as it has become known, has a strong conceptual footprint in the United Kingdom, shaped by empirical research, policy discussion and its accommodation in legal frameworks. Though scholarship has emerged in a number of contexts outside the UK, the extent to which social supply has developed as an internationally recognised concept in criminal justice contexts is still unclear. Drawing on an established international social supply research network across eleven nations, this paper provides the first assessment of social supply as an internationally relevant concept. Data derives from individual and team research stemming from Australia, Belgium, Canada, Czech Republic, Finland, Germany, Hong Kong, the Netherlands, England and Wales, and the United States, supported by expert reflection on research evidence and analysis of sentencing and media reporting in each context. In situ social supply experts addressed a common set of questions regarding the nature of social supply for their particular context including: an overview of social supply research activity, reflection on the extent that differentiation is accommodated in drug supply sentencing frameworks; evaluating the extent to which social supply is recognised in legal discourse and in sentencing practices and more broadly by e.g. criminal justice professionals in the public sphere. A thematic analysis of these scripts was undertaken and emergent themes were developed. Whilst having an absence of local research, New Zealand is also included in the analysis as there exists a genuine discursive presence of social supply in the drug control and sentencing policy contexts in that country. Findings suggest that while social supply has been found to exist as

    Full Text Available Knowledge on variations in vertical, horizontal and temporal characteristics of the soil chemical properties under eucalyptus stumps left in the soil is of fundamental importance for the management of subsequent crops. The objective of this work was to evaluate the effect of eucalyptus stumps (ES left after cutting on the spatial variability of chemical characteristics in a dystrophic Yellow Argisol in the eastern coastal plain region of Brazil. For this purpose, ES left for 31 and 54 months were selected in two experimental areas with similar characteristics, to assess the decomposition effects of the stumps on soil chemical attributes. Soil samples were collected directly around these ES, and at distances of 30, 60, 90, 120 and 150 cm away from them, in the layers 0-10, 10-20 and 20-40 cm along the row of ES, which is in-between the rows of eucalyptus trees of a new plantation, grown at a spacing of 3 x 3 m. The soil was sampled in five replications in plots of 900 m² each and the samples analyzed for pH, available P and K (Mehlich-1, exchangeable Al, Ca and Mg, total organic carbon (TOC and C content in humic substances (HS and in the free light fraction. The pH values and P, K, Ca2+, Mg2+ and Al3+ contents varied between the soil layers with increasing distance from the 31 and 54-monthold stumps. The highest pH, P, K, Ca2+ and Mg2+ values and the lowest Al3+ content were found in the surface soil layer. The TOC of the various fractions of soil organic matter decreased with increasing distance from the 31 and 54-month-old ES in the 0-10 and 10-20 cm layers, indicating that the root (and stump cycling and rhizodeposition contribute to maintain soil organic matter. The C contents of the free light fraction, of the HS and TOC fractions were higher in the topsoil layer under the ES left for 31 months due to the higher clay levels of this layer, than in those found under the 54-month-old stumps. However, highest C levels of the different

    A critical feature of highly pathogenic avian influenza viruses (H5N1 and H7N7) is the efficient intracellular cleavage of the hemagglutinin (HA) protein. H7N7 viruses also exist in equine species, and a unique feature of the equine H7N7 HA is the presence of an eleven amino acid insertion directly N-terminal to a tetrabasic cleavage site. Here, we show that three histidine residues within the unique insertion of the equine H7N7 HA are essential for intracellular cleavage. An asparagine residue within the insertion-derived glycosylation site was also found to be essential for intracellular cleavage. The presence of the histidine residues also appear to be involved in triggering fusion, since mutation of the histidine residues resulted in a destabilizing effect. Importantly, the addition of a tetrabasic site and the eleven amino acid insertion conferred efficient intracellular cleavage to the HA of an H7N3 low pathogenicity avian influenza virus. Our studies show that acquisition of the eleven amino acid insertion offers an alternative mechanism for intracellular cleavage of influenza HA.

The indication for endoprosthesis implantation was no signs of extrabulbar growth. A modified 17–19 mm silicone implant covered with strips from a dura mater graft and medical mesh fabric was used as an orbital implant. The follow-up was 3 to 72 months (mean 32.5 months. All the patients achieved a satisfactory cosmetic effect. None patient was found to have a recurrent orbital tumor. Out of the complications, anterior implant surface denudation was noted in 4 patients. Two patients developed metastases. The absence of recurrent orbital UM at a 6-year follow-up enables primary endoprosthetic replacement of the orbit for UM to be regarded as a safe and reasonable method for patient cosmetic rehabilitation.

    2006-01-01

    We report and review herein our 10-year experience with classic intrafascial supracervical hysterectomy focusing on our long-term experience, evolution of the operative technique, and increased use of this technique. We performed a parallel, observational study with retrospective data to evaluate classic intrafascial supracervical hysterectomy, a laparoscopic hysterectomy technique, at Fayette Medical Center, a community hospital in Northwestern Alabama, USA. Patients comprised a consecutive series of 579 over a 10-year period from November 1992 through November 2002. The classic intrafascial supracervical hysterectomy technique, similar to standard supracervical hysterectomy, leaves the cardinal ligament, uterosacral ligament, vascular supply, and innervation to the upper vagina and cervix intact, but unlike supracervical hysterectomy removes the transition zone and endocervical canal. For 579 patients, the average age was 45.4 years (range, 22 to 92), follow-up was 75.3 months (range, 17 to 137), operating room time was 69 minutes (range, 44 to 370), blood loss was 72 mL (range, 10 to 765), length of hospital stay was 23.2 hours (range, 14 hours to 5 days), time to return to work was 13.2 days (range, 3 to 28). Complications include 11 cervical bleedings, 1 uterine artery bleeding, 1 pelvic hematoma, 1 postoperative ileus, and 16 mucoceles of the cervical stump. Three patients were converted from a laparoscopic to an open procedure (0.52%). Long-term follow-up of up to 137 months shows no adverse events thus far. Classic intrafascial supracervical hysterectomy is a safe procedure with a low short- and long-term complication rate. It has a short recuperation period and high patient satisfaction. It is the procedure of choice when hysterectomy is indicated for benign disease.

    It has become a new lifestyle of using social media (SM) to acquire all kinds of information. The objectives of this study were to determine general practitioner (GP) trainers' current use of SM and their beliefs and attitudes regarding use of SM. A cross-sectional questionnaire survey was taken during a 1-week GP trainers' training program. Data probing GP trainers' use of SM and attitudes toward SM use in clinical work and education were collected and analyzed. Four hundred seven respondents participated in the survey, and the response rate was 61.4%. All the respondents reported that they have at least an SM account. A total of 99.3% of respondents replied that they would add a colleague as a friend via SM; however, only 68.6% of them would add a patient. More than half of the respondents have been contacted by a patient more than five times per year, whereas 67.2% of them attempted to contact a patient by SM less than three times per year. One hundred forty of 407 (34.4%) respondents used SM daily to explore medical information, whereas 42 of 407 (10.3%) contributed new information via SM on a daily basis. Nearly 50% of respondents believed that SM was useful and beneficial. SM is widely used among GP trainers from 11 provinces of China. Most of the participants believed that SM is useful and beneficial to their work. However, there are still some problems for them to use SM in healthcare and medical education, including separating personal and professional use of SM, SM policy, and the quality of information from SM.

  14. 5 years survival after radiotherapy for lung cancer

    Radiotherapy was applied to 256 patients with lung cancer treated in the Institute of Oncology in Krakow in the years 1959-1967. Malignancy had been confirmed throughout in organs of the chest cavity, and diagnosed by microscopic examination. Eleven patients, i.e. 4%, survived 5 years. Survival rate was related to the stage of the disease and the microscopic pattern. Some patients were cured after irradiation of lung cancer, using nominal doses lower than the lethal dose for squamous cell cancer. The specific physical conditions of radiation absorption in the chest cavity evidently made the effective dose inside the cavity much higher than the nominal dose.

    Barriers linked to drug control systems are considered to contribute to inequitable access to controlled medicines, leaving millions of people in pain and suffering. Most studies focus on access to opioids for the treatment of severe (cancer) pain. This study aims to identify specific access barriers for patients with opioid dependence in legislation and regulations of 11 central and eastern European countries. This study builds on a previous analysis of legislation and regulations as part of the EU 7th Framework Access To Opioid Medication in Europe (ATOME) project. An in-depth analysis was undertaken to determine specific barriers for patients with opioid dependence in need of opioid analgesics or opioid agonist therapy (OAT). For each country, the number and nature of specific potential barriers for these patients were assessed according to eight categories: prescribing; dispensing; manufacturing; usage; trade and distribution; affordability; penalties; and other. An additional keyword search was conducted to minimize the omission of barriers. Barriers in an additional category, language, were recorded qualitatively. Countries included Bulgaria, Cyprus, Estonia, Greece, Hungary, Latvia, Lithuania, Serbia, Slovakia, Slovenia and Turkey. Ten of the 11 countries (all except Estonia) showed specific potential barriers in their legislation and regulations. The total number of barriers varied from two (Slovenia) to 46 (Lithuania); the number of categories varied from one (Slovenia) to five (Lithuania). Most specific potential barriers were shown in the categories 'prescribing', 'usage' and 'other'. The total number in a single category varied from one to 18 (Lithuania, prescribing). Individual differences between countries in the same specific potential barrier were shown; for example, variation in minimum age criteria for admission to OAT ranging from 15 (Lithuania, in special cases) to 20 years (Greece). All countries had stigmatizing language in their legislation

    With over 1 million HIV-related deaths annually, quality end-of-life care remains a priority. Given strong public preference for home death, place of death is an important consideration for quality care. This 11 country study aimed to i) describe the number, proportion of all deaths, and demographics of HIV-related deaths; ii) identify place of death; iii) compare place of death to cancer patients iv), determine patient/health system factors associated with place of HIV-related death. In this retrospective analysis of death certification, data were extracted for the full population (ICD-10 codes B20-B24) for 1-year period: deceased's demographic characteristics, place of death, healthcare supply. i) 19,739 deaths were attributed to HIV. The highest proportion (per 1000 deaths) was for Mexico (9.8‰), and the lowest Sweden (0.2‰). The majority of deaths were among men (75%), and those aged <50 (69.1%). ii) Hospital was most common place of death in all countries: from 56.6% in the Netherlands to 90.9% in South Korea. The least common places were hospice facility (3.3%-5.7%), nursing home (0%-17.6%) and home (5.9%-26.3%).iii) Age-standardised relative risks found those with HIV less likely to die at home and more likely to die in hospital compared with cancer patients, and in most countries more likely to die in a nursing home. iv) Multivariate analysis found that men were more likely to die at home in UK, Canada, USA and Mexico; a greater number of hospital beds reduced the likelihood of dying at home in Italy and Mexico; a higher number of GPs was associated with home death in Italy and Mexico. With increasing comorbidity among people ageing with HIV, it is essential that end-of-life preferences are established and met. Differences in place of death according to country and diagnosis demonstrate the importance of ensuring a "good death" for people with HIV, alongside efforts to optimise treatment.

    The present document continues the report CEA-R--2979 - EUR--2768-f. The processing of the data given by the family food enquiry carried out in eleven regions of the European Community, has permitted to determine the food consumption of individuals classified in nine age-groups, in order to study the radioactive contamination levels in the food-chain. The used statistical method is described, and the obtained results are presented in form of double-entry tables giving for each region and for each age-group the mean weekly food-consumption and the contribution of each diet in nutrition principles, in minerals, vitamins, trace elements and calories.

    Chromatographic background drift correction has been an important field of research in chromatographic analysis. In the present work, orthogonal spectral space projection for background drift correction of three-dimensional chromatographic data was described in detail and combined with parallel factor analysis (PARAFAC) to resolve overlapped chromatographic peaks and obtain the second-order advantage. This strategy was verified by simulated chromatographic data and afforded significant improvement in quantitative results. Finally, this strategy was successfully utilized to quantify eleven antibiotics in tap water samples. Compared with the traditional methodology of introducing excessive factors for the PARAFAC model to eliminate the effect of background drift, clear improvement in the quantitative performance of PARAFAC was observed after background drift correction by orthogonal spectral space projection.

    2005-01-01

    We derive, for spacetimes admitting a Spin(7) structure, the general local bosonic solution of the Killing spinor equation of 11-dimensional supergravity. The metric, four-form, and Killing spinors are determined explicitly, up to an arbitrary eight-manifold of Spin(7) holonomy. It is sufficient to impose the Bianchi identity and one particular component of the four-form field equation to ensure that the solution of the Killing spinor equation also satisfies all the field equations, and we give these conditions explicitly

    2006-01-01

    We classify all the structure groups which arise as subgroups of the isotropy group (Spin(7)xR 8 )xR, of a single null Killing spinor in 11 dimensions. We construct the spaces of spinors fixed by these groups. We determine the conditions under which structure subgroups of the maximal null structure group (Spin(7)xR 8 )xR may also be embedded in SU(5), and hence the conditions under which a supersymmetric spacetime admits only null, or both timelike and null, Killing spinors. We discuss how this purely algebraic material will facilitate the direct analysis of the Killing spinor equation of 11 dimensional supergravity, and the classification of supersymmetric spacetimes therein

    This research documents and demonstrates viable approaches using existing materials, tools and technologies in owner-conducted deep energy retrofits (DERs). These retrofits are meant to reduce energy use by 70% or more, and include extensive upgrades to the building enclosure, heating, cooling and hot water equipment, and often incorporate appliance and lighting upgrades as well as the addition of renewable energy. In this report, 11 Northern California (IECC climate zone 3) DER case studies are described and analyzed in detail, including building diagnostic tests and end-use energy monitoring results. All projects recognized the need to improve the home and its systems approximately to current building code-levels, and then pursued deeper energy reductions through either enhanced technology/ building enclosure measures, or through occupant conservation efforts, both of which achieved impressive energy performance and reductions. The beyond-code incremental DER costs averaged $25,910 for the six homes where cost data were available. DERs were affordable when these incremental costs were financed as part of a remodel, averaging a $30 per month increase in the net-cost of home ownership.

    We study in detail the structure of the Lorentz covariant, spacetime supersymmetric 11-dimensional supermembrane theory. We show that for a flat spacetime background, the spacetime supersymmetry becomes an N=8 world volume (rigid) supersymmetry in a ''physical'' gauge; we also present the field equations and transformation rules in a ''lightcone'' gauge. We semiclassically quantize the closed toroidal supermembrane on a spacetime (Minkowski) 4 x (flat 7-torus), and review some mathematical results that are relevant for path integral quantization.

  6. Eleven Colors That Are Almost Never Confused

    1.1. Three functions of color vision. Setting aside the complex psychological effects of color, related to esthetics, fashion, and mood, three relatively basic functions of color vision, which can be examined scientifically, are discernable. (1) With the eye in a given state of adaptation, color vision allows the perception of signals that otherwise would be below threshold, and therefore lost to perception. Evidence for this comes from a variety of two-color threshold experiments. (2) Visible contours can be maintained by color differences alone, regardless of the relative radiances of the two parts of the field whose junction defines the border. For achromatic vision, contour disappears at the isoluminant point. (3) Color specifies what seems to be an absolute property of a surface, one that enhances its recognizability and allows a clearer separation and classification of non-contiguous elements in the visual field.

    Full Text Available Background: Minimally invasive surgery is the current approach to perform heminephroureterectomy (HN in children. This can be obtained through a transperitoneal (TP or a retroperitoneal approach. Here, we report our experience using a TP approach. Materials and Methods: From 2005 to 2014, 22 TP laparoscopic upper poles HN were performed at our institution. There were nine girls and 13 boys aged between 20 months and 6 years (mean age 3.9. Eight patients were diagnosed prenatally, 17 patients presented with urinary tract infection (UTI and three with vomiting and failure to thrive. The indication for HN was reflux nephropathy and UTI in non-functioning upper pole in 19 patients and cystic dysplasia in 1 patient. The surgical technique involved the following steps: Cystoscopic recognition; positioning of 3-4 trocar (right HN; identification of the kidney (detachment of the colon; isolation and low ligation of the dilated ureter; decrossing from renal vessels; section of the parenchyma by LigaSure; haemostasis with clips and LigaSure; drain. Results: The mean operative time was 154 min (range: 81-220 min. All patients were discharged from the 2 nd to 4 th day. Neither major complication nor conversion was recorded. 1 patient presented leakage of urine for 7 days from the drainage which resolved spontaneously. At ultrasound follow-up, 5 patients showed a secondary perirenal cyst, 2-5 cm diameter that resolved spontaneously. Conclusion: The results indicate that laparoscopic upper pole heminephrectomy is the treatment of choice in cases of non-functioning dilated lower segments of duplicated kidneys. The use of laparoscopic approach offers a good working space, a good visual control of the vessels and allows a very low isolation of the ureteral stump which counterbalance the peritoneal violation.

  8. Lean years

    The author attempts to take stock of five critical systems of resources: Energy, mineral resources, food, water, and human abilities. All five systems have been integrated, to an ever-increasing extent in global control systems. These control systems determine how many people, in what parts of the world, will be faced with hunger, cold, or unemployment. The author tries to find out who is in charge of these control systems, how they have come into existence, and on what strategies they are based. In the final chapter, ''Policy of survival'', the author states that the secret of survival in the lean years to come is still in the dark. Man's most fundamental desire is to be human, i.e. to be in harmony with nature both psychologically and biologically. Politics should take account of this and provide us with the means for doing what is necessary.

    Many Lamiaceae species are consumed in the Lebanese cuisine as food or condiment and are largely used in the traditional medicine of Lebanon to treat various diseases, including microbial infections. In this article we report the traditional medicinal uses of eleven Lamiaceae species: Coridothymus capitatus L., Lavandula stoechas L., Lavandula angustifolia Mill., Mentha spicata L. subsp. condensata , Origanum syriacum L., Rosmarinus officinalis , Salvia fruticosa Miller., Satureja cuneifolia Ten., Satureja thymbra L., Thymbra spicata L., and Vitex agnus-castus L. and study the chemical composition and antimicrobial activity of their essential oils (EOs). Our survey showed that Lamiaceae species are mainly used against gastrointestinal disorders and microbial infections. Chemical analysis of the EOs obtained from these plants allowed us to identify seventy-five compounds describing more than 90% of the relative composition of each EO. Essential oils with high amounts of thymol and carvacrol possessed the strongest antimicrobial activity. As expected, these two compounds demonstrated an interesting antifungal efficacy against the filamentous fungus T. rubrum . Our results confirmed that some of the Lamiaceae species used in Lebanon ethnopharmacological practices as antimicrobial agents do possess antibacterial and antifungal potential consistent with their use in alternative or complementary medicine.

    The results of radiotherapy of 374 cases of cancer of the cervix uteri, 163 cases of carcinoma of the endometrium, 24 cases of cancer of the cervival stump and 16 cases of sarkoma of the uterus carried out during the years 1967 to 1972 are shown. The absolute 5-year cure rates in our case material were 60,4 % for cancer of the cervix uteri and 73,0 % for carcinoma of the endometrium. In comparison with the treatment results reported in the years 1962 to 1966 an increase in radiotherapeutical efficiency was found, amounting to 8,8 % in case of cancer of the cervix uteri and 13,2 % in case of carcinoma of the endometrium. We also compared and analysed the different cure rates in case of primary irradiation (52,6 % resp. 55,8 %) as opposed to postoperative radiotherapy '76,9 % resp. 81,1 % cure rates). The frequency of radiation injuries and the rate of recurrence or metastases, as well as the incidence of concomitant diseases and complications have been reported and compared with those of other clinics.

    The crude major lower limb amputation procedure rate is 8.8 per 100,000 of the population per year in Taiwan. From January 2002 to October 2006, patients that received major lower limb amputation in our department were enrolled in this study. Retrospective chart reviews concerning different factors that can affect the eventual postoperative functional status were investigated. Factors that affected the length of hospital stay included duration before amputation (P usage time were initial infection status (P = 0.021), renal function (P = 0.01), patient educational level (P = 0.016), and pretraining waiting time (P = 0.003). The duration of prosthetic training was affected by patient educational level (P = 0.004) and marital status (P = 0.024). In addition, subjective satisfaction about the usage of prosthesis was affected by pretraining waiting time (P = 0.001) and daily prosthesis usage time (P usage time was closely related to life quality improvement (P usage (P usage time of the prosthesis. Surgeons can make some contribution to accelerate amputation wound healing and stump maturation by choosing the correct operating procedure, delicately managing the soft tissue, and ascertaining proper wound care to improve the outcome.

    Full Text Available Este trabalho objetivou isolar fungos causadores da podridão-branca da madeira, a partir de basidiocarpos e de fragmentos de madeira de eucalipto coletados em várias regiões do país, bem como testar seu potencial de degradação de cepas e raízes mortas em plantios comerciais de eucalipto, após o corte raso. Para o isolamento dos fungos foi desenvolvido um meio de cultura de serragem de eucalipto-ágar. Dentre 292 isolados obtidos e submetidos ao teste de Bavendamm, 144 foram classificados como causadores de podridão-branca, capazes de produzir fenoloxidases. Dentre as nove relações C/N testadas, observou-se uma tendência de ocorrer maior degradação de cavacos naquelas iguais a 60 : 1, 200 : 1 e 300 : 1. Utilizando a relação C/N igual a 60 : 1, realizaram-se dois experimentos para avaliar a degradação de cavacos de Eucalyptus saligna por isolados fúngicos de podridão-branca. No primeiro experimento, avaliado aos 90 dias de incubação, foram selecionados sete isolados, que causaram perda de peso em cavacos superior ou igual à causada por Trametes versicolor, usado para comparação. No segundo experimento foram testados 46 isolados fúngicos. Dentre os mais eficientes estavam os sete isolados selecionados no primeiro teste, além de outros quatro isolados. Baseado na análise de DNA, seis isolados foram identificados, sendo três pertencentes à espécie Pycnoporus sanguineus, um ao gênero Peniophora sp., um ao gênero Pestalotiopsis sp. e um ao gênero Ganoderma sp.The aim of this work was to isolate native wood white-rot fungi from fungal fruit-bodies and eucalyptus wood fragments from different regions of Brazil and to test their potential for degrading dead stumps and roots in Eucalyptus plantings after harvest. Fungi isolates were obtained in a culture medium composed by Eucalyptus sawdust and agar. Among 292 isolates submitted to the Banvedamm test, 144 were classified as phenoloxidases producing isolates.

    Full Text Available Most Eucalyptus plantations in Brazil aim the production of paper and charcoal, but the use of the species for lumbering, construction and extraction of essential oil has increased. Eleven species of Eucalyptus were assessed in regard to their essential oil production potential, nine never used before for commercial, essential oil extraction. Assessements were compared with Eucalyptus citriodora and Eucalyptus globulus, already explored in oil production for perfume and medical purposes, aiming to increase the availability of commercial species and the relationship between oil production and climatic conditions. Eucalyptus leaves were seasonally sampled (three months interval for distillation and determination of productivity and chemical composition of oil - contents of oils main components. Eucalyptus viminalis showed the highest potential for cineol, and standed out among the species not yet used commercially. Influenced by soil moisture contents and air temperature, the lowest and the highest oil production happened respectively in Spring and Summer. Water deficiency in Spring caused the lowest oil production. In the Summer, on the other hand, the highest oil production was observed when temperatures were higher and no water deficiency registered. There was no climatic influence on the main oil chemical component.A maioria das plantações de Eucalyptus brasileiras tem como objetivo a produção de papel e carvão, mas o uso das espécies para madeira, construção e extração de óleo essencial tem aumentado.

    The purpose of this study was to determine the best wound infection prophylaxis in pediatric acute appendicitis. From 1969 to 1995 inclusive, 453 consecutive pediatric patients at the same children's hospital had an appendix with acute inflammation (acute appendicitis) removed by the same staff surgeon and his resident. The stump was not inverted, and chromic catgut was used throughout. No intraperitoneal antibiotics, irrigation, or drains were used, and the skin closure was with silk sutures initially and then with staples since 1986. The infants and children were divided into 6 consecutive groups of 52 to 96 patients, with each group lasting 2 to 5 years. The wound treatment groups were as follows: no treatment, drain or pack, drain or pack plus antibiotic powder, antibiotic powder, preoperative intravenous antibiotic plus antibiotic powder, and preoperative intravenous antibiotic. The wound Penrose drain, one half-inch gauze pack, and/or antibiotic powder (ampicillin, 1977-1981; cefoxitin, 1982-1995) were all placed in the subcutaneous space. There were a total of 50 (11%) wound infections (pus) that occurred between 4 and 40 days when no antibiotic powder was used and 2 to 14 days with antibiotic powder. In all 6 groups of patients, no organism was grown in most (80%) infections and Escherichia coli was the second commonest (12%). The serous ooze, which occurred only with the use of antibiotic powder (8%), was seen between 6 and 18 days, and no organism was ever cultured. The patients with preoperative (or intraoperative) intravenous antibiotics (cefoxitin) plus wound antibiotic powder (cefoxitin) had the lowest infection rate (2.5%). When this group was compared with the baseline group 1 (no treatment), it was the only group in which wound treatment made a significant difference (P = .003).

    Forty-two patients with traumatic blunt splenic injuries were admitted over a six year period. Vehicular-related collisions and fall from height accounted for the injuries in 38 (90.5%) of them. Eleven (26.2%) underwent immediate surgery (7 splenectomy and 4 splenorrhaphy), while the remaining 31 patients were treated nonoperatively of which 3 underwent angio-embolisation. Twenty seven patients had either grade III or IV splenic injuries. Operative management was more likely in patients with lower haemoglobin or with more severe splenic injury. Nonoperative management can be adopted in patients with blunt isolated splenic injuries but operative management is still indispensable in certain instances.

    A 448-year teak chronology from northwestern Thailand is used to assess past changes in the strength of the summer monsoon. The chronology is based on 30 living trees that extend from 1604 to 2005, and a 47-stump chronology that spans from 1558 to 1903. We used methods of cross dating and chronology building that address problems specifically found in teak. The result is a robust chronology with strong signal strength back to 1600 ad, and with variability retained at the multi-decadal scale. Variability in annual growth in teak from this area is dependent on rainfall and soil moisture availability at both the beginning and end of the monsoon season as confirmed by comparisons with temperature, rainfall and PDSI data. These correlation analyses confirm that our record is a proxy for summer monsoon strength and/or duration, and highlight the importance of soil moisture availability in the seasons of transition. The chronology reveals two prominent periods of decadal-scale drought in the early and mid 1700s that correspond to persistently warm sea surface temperature anomalies in the tropical Pacific as derived from Galapagos Island coral records. Speleothem data from central India also indicate protracted periods of drought for the 1700s. While these broad-scale eighteenth-century persistent droughts may be related to protracted El Nino-like conditions in the tropical Pacific, regional climate forcing over the Indian Ocean and western Pacific sectors appears to be a strong contributor as well. Spectral analyses reveal power in the ENSO range of variability from 2.2 to 4 years, and at the multi-decadal scale at 48.5 years. (orig.)

    Management of craniopharyngioma in children is challenging, and their quality of life can be significantly affected. Series describing this from low-middle income countries (LMIC) are few. The study provides a retrospective chart review of pediatric patients craniopharyngioma between 2003 and 2014, and treated at King Hussein Cancer Center, Jordan. Twenty-four patients (12 males) were identified. Median age at diagnosis was 7.4 years (0.9-16.4 years). Commonest symptoms were visual impairment and headache (71%). Review of seventeen preoperative MRIs showed hypothalamic involvement in 88% and hydrocephalus in 76%. Thirteen patients (54%) had multiple surgical interventions. Five patients (21%) had initial gross total resection. Eleven patients (46%) received radiotherapy and six (25%) intra-cystic interferon. Five years' survival was 87 ± 7% with a median follow-up of 4.5 years (0.3-12.3 years). Four patients (17%) died; one after post-operative cerebral infarction and three secondary to hypothalamic damage. At their last evaluation, all but one patient required multiple hormonal supplements. Ten patients (42%) had best eye visual acuity (VA) >20/40, and four (16%) were legally blind. Eleven patients (46%) were overweight/obese; one had gastric bypass surgery. Seven patients had hyperlipidemia, and eight developed fatty liver infiltration. Eleven patients (65%) were attending schools and one at college. Nine of the living patients (53%) expressed difficulty to engage in the community. Management of pediatric craniopharyngioma is particularly complex and demanding in LMIC. Multidisciplinary care is integral to optimize the care and minimize the morbidities. A management outline for LMIC is proposed.

    Full Text Available The construction of reservoirs and hydropower plants was accelerated in the past century due to the increasing aridity in many parts of the world. The effect of water regulations on the abundance of mosquito vectors is controversial. In this paper, the habitat preference of mosquitoes was investigated based on a 30-years long collection of the mosquito data in Hungary and military maps and satellite images. Three time phases of the analyzed section in the Danube River were analyzed in order to characterize the impact of human influence on mosquito habitats: the semi-natural phase, the post channelization phase and the post hydropower dam state. Geographical data referring to the years 1790, 1820, 1830, 1870, 1946 and 1955 were based on military maps, whereas the years 2004 and 2013 were analyzed by satellite imagery. The Amoros-like eupotamon A - plesiopotamon line represents an increasing gradient of habitat-suitability for mosquitoes. The habitat-preference of different mosquitoes to the Amoros-classified water habitats was based on a monographic collection data. This dataset contains the collecting and trapping results from the 1960s to the early 2000s in Hungary. We found that human-induced changes had prolonged impact on mosquito-suitable habitats, although the effect can be different for diverse mosquito species. The increase of the evenness of the mosquito fauna was seen since the mid-20th century, after the primary river regulation. The increasing areal extension of relatively warm and nutrient-rich water habitats had positive effects on the more rare members of the mosquito fauna, such as the potential malaria vector mosquito Anopheles algeriensis according to the model results. Summarizing, we found a strong, positive link between anthropogenic interventions and the mosquito diversity in water ecosystems.

    Full Text Available This article is written in memory of Professor Björn Andersson (1939-2013, the pioneer in the emerging field of science education research in Sweden. In 1976 he was the first to present a PhD in the field of science education in the Nordic countries, and later he became the first to hold a chair in this field in Sweden. The article lifts his PhD (Andersson, 1976 as an example for how a PhD should be written and argues that it should be re-read today. The theses has a clear purpose and research agenda, a well-argued theoretical foundation, a solid anchoring to classroom context, sound choices of methods, excellent analysis of empirical data, both qualitative and qualitative, and a clear presentation of findings and implications. In the decades that followed, Björn was the key person to build the field of science education research in Sweden. This article presents just a few aspects of his wide scope of interests and activities as they have unfolded on the national as well as on the international scene. Björn brought international perspectives to Sweden, and he also represented Sweden abroad. Now, nearly 40 years after Björn graduated, the field of science education in Sweden and the other Nordic countries is well established and flourishing. Björn combined a series of qualities and can serve as a model for new generations: a concern for the learner, teachers and their classroom activities, and a care for coworkers. He provides an example of how to combine an academic activity with a devotion to improve the quality of teaching and learning.

    Later this year or early next year site construction work is due to start on two new nuclear power projects in Britain. There has been a gap of ten years since the last start of construction on a nuclear project in the country. Coupled with this is a, long overdue, rationalisation of the complicated management structure of the National Nuclear Corporation and its operating subsidary, the Nuclear Power Company, with a new Chairman, Denis Rooney, taking up his duties on July 1. At the end of last year the Government announced a program of nuclear power plant construction which will involve the ordering of at least one new station per year for a ten year period starting in 1982 and both nationally and internationally the Prime Minister, Margret Thatcher, has declared her conviction in the need for the industrialised nations of the world to develop further the use of nuclear energy as an alternative to oil.

    This report presents the Danish Design Reference Year based on observed data from 2001 - 2010. In various sectors - i.e. building and construction, energy, etc. - the climate and weather usually plays a part in a given project. The Danish Design Reference Year dataset is a collection of data series for eleven specific parameters, that each represents a typical year in Denmark. The uses of the dataset may vary from simulations to statistical analysis, graphical overviews etc. The Danish land areas have been sectionalised into five to six climatological zones depending on the parameter, each characterized by distinct diurnal and yearly variations. The dataset consists of observed data from one station located within and representing each zone. In addition to the complete Danish Design Reference Year dataset, a subset specifically selected to be used for energy performance calculations for obtaining a building permit is included. (Author)

    Full Text Available We present two parallel and 32 000 years long trajectories of episodic ceramic technology use in Eurasian pre-Neolithic hunter-gatherer societies. In eastern, Asian trajectory the pottery was produced from the beginning. Ceramic figurines mark the western, European trajectory. The western predates the eastern for about eleven millennia. While ceramic cones and figurines first appeared in Central Europe at c. 31 000 cal BC the earliest vessels in eastern Asia was dated at c. 20 000 cal BC. We discuss women’s agency, perception of containment, ‘cross-craft interactions’, and evolution of private property that that may influenced the inventions of ceramic (pyrotechnology.

    The aim of this study was to determine the incidence rate and clinical features of second primary pancreatic ductal carcinoma (SPPDC) in the remnant pancreas after pancreatectomy for pancreatic ductal carcinoma (PDC). Data of patients undergoing R0 resection for PDC at a single high-volume center were reviewed. SPPDC was defined as a tumor in the remnant pancreas after R0 resection for PDC, and SPPDC met at least one of the following conditions: 1) the time interval between initial pancreatectomy and development of a new tumor was 3 years or more; 2) the new tumor was not located in contact with the pancreatic stump. We investigated the clinical features and treatment outcomes of patients with SPPDC. This study included 130 patients who underwent surgical resection for PDC between 2005 and 2014. Six (4.6%) patients developed SPPDC. The cumulative 3- and 5-year incidence rates were 3.1% and 17.7%, respectively. Four patients underwent remnant pancreatectomy for SPPDC. They were diagnosed with the disease in stage IIA or higher and developed recurrence within 6 months after remnant pancreatectomy. One patient received carbon ion radiotherapy and survived 45 months. One patient refused treatment and died 19 months after the diagnosis of SPPDC. The incidence rate of SPPDC is not negligible, and the cumulative 5-year incidence rate of SPPDC is markedly high. Post-operative surveillance of the remnant pancreas is critical for the early detection of SPPDC, even in long-term survivors after PDC resection. Copyright © 2016 IAP and EPC.

    The Ecological Monitoring and Compliance program, funded through the U.S. Department of Energy, National Nuclear Security Administration Nevada Operations Office, monitors the ecosystem of the Nevada Test Site (NTS) and ensures compliance with laws and regulations pertaining to NTS biota. This report summarizes the program's activities conducted by Bechtel Nevada during fiscal year 2001. Program activities included: (1) biological surveys at proposed construction sites, (2) desert tortoise compliance, (3) ecosystem mapping and data management, (4) sensitive species and unique habitat monitoring, and (5) biological monitoring at the HAZMAT Spill Center. Biological surveys for the presence of sensitive species were conducted for 23 NTS projects. Eleven sites were in desert tortoise habitat. These projects have the potential to disturb a total of 588 acres, where 568 acres of disturbance would be off-road driving. No tortoises were found in or displaced from project areas, and no tortoise s were accidentally injured or killed at project areas. One tortoise was crushed by a vehicle on a paved road. A topical report describing the classification of habitat types on the NTS was completed and distributed. The report is the culmination of three years of field vegetation mapping and the analysis of vegetation data from over 1,500 ecological landform units. Compilation of historical wildlife data was initiated. A long-term monitoring plan for important plant species that occur on the NTS was completed. Site-wide monitoring was conducted for the western burrowing owl, bat species of concern, wild horses, and raptor nests. Sixty-nine of 77 known owl burrows were monitored. As in previous years, some owls were present year round on the NTS. An overall decrease in active owl burrows was observed within all three ecoregions (Mojave Desert, Transition, Great Basin Desert) from October through January. An increase in active owl burrows was observed from mid March to early April. A

    To compare the microtensile bond strength (microTBS) to enamel of 10 contemporary adhesives, including three one-step self-etch systems, four two-step self-etch systems and three two-step total-etch systems, with that of a conventional three-step total-etch adhesive. Resin composite (Z100, 3M) was bonded to flat, #600-grit wet-sanded enamel surfaces of 18 extracted human third molars using the adhesives strictly according to the respective manufacturer's instructions. After storage overnight in 37 degrees C water, the bonded specimens were sectioned into 2-4 thin slabs of approximately 1 mm thickness and 2.5 mm width. They were then trimmed into an hourglass shape with an interface area of approximately 1 mm2, and subsequently subjected to microTBS-testing with a cross-head speed of 1 mm/minute. The microTBS to enamel varied from 3.2 MPa for the experimental one-step self-etch adhesive PQ/Universal (self-etch) to 43.9 MPa for the two-step total-etch adhesive Scotchbond 1. When compared with the conventional three-step total-etch adhesive OptiBond FL, the bond strengths of most adhesives with simplified application procedures were not significantly different, except for two one-step self-etch adhesives, experimental PQ/Universal (self-etch) and One-up Bond F, that showed lower bond strengths. Specimen failures during sample preparation were recorded for the latter adhesives as well.

    We report the results of a medium-narrowband 2 μm line survey covering 5.8 deg 2 near the Galactic plane. We confirm 11 new field Wolf-Rayet stars along three lines of sight probing the inner Galaxy, demonstrating the capability to uncover distant and highly reddened populations of Galactic wind-borne emission-line stars suffering extinction as high as A V ∼ 40 and as distant as 9 kpc down to modest magnitude limits of K s ∼ 12.5. All stars are of subtype WC7-8, with median distance d = 6 kpc and median extinction A K s = 2.5. Over the fields surveyed, the density of Wolf-Rayet stars to limiting magnitude K s ∼ 12.5 was found to be 1.9 deg –2 . We compare this to models which predict their distribution within the Galaxy and find that, even neglecting survey and subtype incompleteness, they consistently underpredict the number of newly discovered stars along the surveyed lines of sight.

  4. Comparative embryology of eleven species of stony corals (Scleractinia.

    Directory of Open Access Journals (Sweden)

    Nami Okubo

    Full Text Available A comprehensive understanding of coral reproduction and development is needed because corals are threatened in many ways by human activity. Major threats include the loss of their photosynthetic symbionts (Symbiodinium caused by rising temperatures (bleaching, reduced ability to calcify caused by ocean acidification, increased storm severity associated with global climate change and an increase in predators caused by runoff from human agricultural activity. In spite of these threats, detailed descriptions of embryonic development are not available for many coral species. The current consensus is that there are two major groups of stony corals, the "complex" and the "robust". In this paper we describe the embryonic development of four "complex" species, Pseudosiderastrea tayamai, Galaxea fascicularis, Montipora hispida, and Pavona Decussata, and seven "robust" species, Oulastrea crispata, Platygyra contorta, Favites abdita, Echinophyllia aspera, Goniastrea favulus, Dipsastraea speciosa (previously Favia speciosa, and Phymastrea valenciennesi (previously Montastrea valenciennesi. Data from both histologically sectioned embryos and whole mounts are presented. One apparent difference between these two major groups is that before gastrulation the cells of the complex corals thus far described (mainly Acropora species spread and flatten to produce the so-called prawn chip, which lacks a blastocoel. Our present broad survey of robust and complex corals reveals that prawn chip formation is not a synapomorphy of complex corals, as Pavona Decussata does not form a prawn chip and has a well-developed blastocoel. Although prawn chip formation cannot be used to separate the two clades, none of the robust corals which we surveyed has such a stage. Many robust coral embryos pass through two periods of invagination, separated by a return to a spherical shape. However, only the second of these periods is associated with endoderm formation. We have therefore termed the first invagination a pseudo-blastopore.

    Roeda, D.

    1982-01-01

    This thesis deals with some applications of the short lived cyclotron produced radioisotope carbon-11 (half life 20.4 min.) For medical use. Both chemical manipulation of highly radioactive gamma emitting material in order to prepare suitable 11 C-labelled radiopharmaceuticals and two clinical studies are discussed. The first chapter comprises a general introduction concerning the application of the ''tracer principle'' to the short lived positron emitting radionuclides 18 F, 11 C, 13 N and 15 O in medicine. Chapter two deals with the synthesis of 11 COCl 2 . This product is a useful new 11 C-synthon with many potential applications. In chapter three the synthesis of 11 C-urea from 11 C-phosgene for medical use is described. The method uses the reaction of 11 COCl 2 with aqueous ammonia. Chapter four deals with the synthesis of 11 C-barbituric acids and 11 C-hydantoins and presents a clinical study on epilepsy, using 2- 11 C-5,5-diphenylhydantoin ( 11 C-DPH). Patients having intractable epilepsy and patients having no epilepsy were given intravenously a single dose of 11 C-DPH after which the accumulation of the radioactivity in the brain was followed by positron emission tomography. No regional concentration differences could be found near epileptic foci. There was a faint indication that there are some differences in uptake for whole brain between the two categories of patients. (Auth.)

Dry matter (DM accumulation was measured repeatedly, and contents of minerals N, P, K, Ca and Mg at maturity. Annual crops accumulated above-ground biomass faster than perennials, while perennials had higher DM accumulation rates below ground. Seeds had high concentrations of N and P, while green biomass had high concentrations of K and Ca. Stems and roots had low concentrations of minerals. Concentrations of K and P were high in quinoa and caraway, and that of P in buckwheat. Hemp and nettle had high Ca concentrations, and quinoa had high Mg concentration. N and P were efficiently harvested with seed, Ca and K with the whole biomass. Perennials could prevent soil erosion and add carbon to the soil in the long term, while annuals compete better with weeds and prevent erosion during early growth. Nutrient balances in a field could be modified and nutrient leaching reduced by careful selection of the crop and management practices.;

    Full Text Available Abstract Background Brucellosis is an endemic disease present in many countries worldwide, but it is rare in Europe and North America. Nevertheless brucella is included in the bacteria potentially used for bioterrorism. The aim of this study was the investigation of the antibiotic susceptibility profile of brucella isolates from areas of the eastern Mediterranean where it has been endemic. Methods The susceptibilities of 74 Brucella melitensis isolates derived from clinical samples (57 and animal products (17 were tested in vitro. The strains originate from Crete (59, Cyprus (10, and Syria (5. MICs of tetracycline, rifampicin, streptomycin, gentamicin, norfloxacin, ciprofloxacin, levofloxacin, trimethoprim/sulfamethoxazole, ampicillin, amoxicillin/clavulanic acid, and erythromycin were detected by E-test method. The NCCLS criteria for slow growing bacteria were considered to interpret the results. Results All the isolates were susceptible to tetracycline, streptomycin, gentamicin, ciprofloxacin, norfloxacin, and levofloxacin. Two isolates presented reduced susceptibility to rifampicin (MIC value: 1.5 mg/l and eight to SXT (MIC values: 0.75–1.5 mg/l. Erythromycin had the highest (4 mg/l MIC90value and both norfloxacin and erythromycin the highest (1.5 mg/l MIC50 value. Conclusion Brucella isolates remain susceptible in vitro to most antibiotics used for treatment of brucellosis. The establishment of a standardized antibiotic susceptibility method for Brucella spp would be useful for resistance determination in these bacteria and possible evaluation of bioterorism risks.

    1988-01-01

    We study in detail the structure of the Lorentz covariant, spacetime supersymmetric 11-dimensional supermembrane theory. We show that for a flate spacetime background, the spacetime supersymmetry becomes an N = 8 world volume (rigid) supersymmetry in a ''physical'' gauge; we also present the field equations and transformation rules in a ''lightcone'' gauge. We semiclassically quantize the closed torodial supermembrane on a spactime (Minkowski) 4 x (flat 7-torus), and review some mathematical results that are relevant for path integral quantization. copyright 1988 Academic Press, Inc

  16. Eleven essential steps to purchasing or selling a medical practice.

    Science.gov (United States)

    Barrett, William

    2014-01-01

    Based on our experience in representing more than 100 doctors and medical specialists in practice sales and acquisitions, we have identified 11 key considerations important to a deal. There are several issues to consider while going through the process of buying or selling a practice including the implementation of a "letter of intent" as a first step rather than drafting a contract, securing a lease, and verifying the property is not in violation of the local zoning requirements. There are also considerations with regard to the patients, which range from how will the accounts receivable at the time of the closing be handled to who is responsible for the handling of continued treatment in an ongoing case after a deal is finalized. This article details these considerations and more.

  17. New compactifications in seven and eleven dimensional supergravity theories

    International Nuclear Information System (INIS)

    Pernici, M.; Sezgin, E.

    1984-08-01

    It is found that the N=4 gauged supergravity in d=7 spontaneously compactifies on direct product of anti-deSitter space (AdS) with a 3-sphere (non-supersymmetric: N=0), or with 3-hyperboloid (N=2). Similarly the N=2 gauged supergravity in d=7 compactifies on AdSxH 3 (N=1). The possibility of σ-model induced compactification of ungauged d=7 N=2 supergravity coupled to one vector multiplet on (Minkowski) 4 x Tear Drop x S 1 is discussed. The case of d=11 supergravity is also studied, and two new compactifications are found: AdS x non-Einstein squashed S 7 (n=0) and AdS x non-Einstein SU(2) bundle over CP 2 (N=0). (author)

START finalists were selected based on the clarity of their requests for technical assistance and the ability of START to successfully work with their projects or community. Technical experts from DOE and its National Renewable Energy Laboratory (NREL) will work directly with community-based project teams to analyze local energy issues and assist the Tribes in moving their projects forward. In Alaska, the effort will be bolstered by DOE-IE's partnership with the Denali Commission, which will provide additional assistance and expertise, as well as funding to fuel the Alaska START initiative.

    Full Text Available Perspectives on Federalism starts off its ninth year with this issue which gathers, as usual, a series of multi-disciplinary pieces. Almost two years have passed since we started our collaboration with De Gruyter, and our journal has since then enjoyed continued growth and has been acquiring international visibility. 2017 is going to be rich in surprises for our readers, with a wealth of interesting projects and special issues which will increase the already high standard of the journal. 2016 was also a very challenging year for scholars interested in federalism; the start of the Trump Presidency and the results of the referendum on Brexit held on 23 June 2016 are just two examples.

  2. Emergent technologies: 25 years

    Rising, Hawley K.

    2013-03-01

    This paper will talk about the technologies that have been emerging over the 25 years since the Human Vision and Electronic Imaging conference began that the conference has been a part of, and that have been a part of the conference, and will look at those technologies that are emerging today, such as social networks, haptic technologies, and still emerging imaging technologies, and what we might look at for the future.Twenty-five years is a long time, and it is not without difficulty that we remember what was emerging in the late 1980s. Yet to be developed: The first commercial digital still camera was not yet on the market, although there were hand held electronic cameras. Personal computers were not displaying standardized images, and image quality was not something that could be talked about in a standardized fashion, if only because image compression algorithms were not standardized yet for several years hence. Even further away were any standards for movie compression standards, there was no personal computer even on the horizon which could display them. What became an emergent technology and filled many sessions later, image comparison and search, was not possible, nor the current emerging technology of social networks- the world wide web was still several years away. Printer technology was still devising dithers and image size manipulations which would consume many years, as would scanning technology, and image quality for both was a major issue for dithers and Fourier noise.From these humble beginnings to the current moves that are changing computing and the meaning of both electronic devices and human interaction with them, we will see a course through the changing technology that holds some features constant for many years, while others come and go.

    This year marks the 50th anniversary of one of the major landmarks of modern physics - the discovery of the positron, the antimatter counterpart of the electron. This provided the first evidence for antimatter, and it was also unprecedented for the existence of a new particle to have been predicted by theory. The positron and the concepts behind it were to radically change our picture of Nature. It led to the rapid advancement or our understanding, culminating some fifteen years later with the formulation of quantum electrodynamics as we now know it. (orig./HSI).

  3. Toward the year 2000.

    Science.gov (United States)

    1973-12-01

    If the world population continues to grow at its present rate, in only about 35 more years there will be an additional 3.5 billion people. Although it is likely that the growth rate will slow down in the future, there will be an increase of between 2.3-3.5 billion people by the year 2000. At that time the Asian, African, and Latin American regions of the world will account for between 81-84% of world population, regardless of whether there is a fertility decline. Simultaneously, the populations of Europe and North America will decrease from 26 to between 16-19%. The People's Republic of China is now working to contain population increase, but despite the efforts for every 10 Chinese alive in 1970 there will be 15 in the year 2000. For the other 9 most populous less developed countries, there will be nearly 20 persons for every 10. As this figure is 12 in the year 2000 for every 10 Russians or Americans in 1970, a significant reduction in the growth rate of population in the 10 largest less developed countries would do much to reduce the world's population problems. The number of children born between now and the year 2000 depends on the fertility of all women in the childbearing ages during that period. Finally, as the population of the world continues to increase, there will be a marked concentration of the world's children in the poorer nations, and this will be a major problem in these developing countries.

    Events in the Canadian nuclear industry from June 1990 to June 1991 are highlighted, with emphasis on the role of the Canadian Nuclear Association and its committees. The sale of a second 600 MW CANDU reactor to Korea by AECL was finalized in December 1990. Scoping hearings for the review of the Canadian fuel waste disposal concept were completed during the year. In September 1990 the New Democratic Party came to power in Ontario, and announced a moratorium on construction of new nuclear plants pending hearings, except that all four reactors of Darlington A are to be completed. Despite excellent performance by the newer CANDU units, Ontario Hydro has found it necessary to devote increased resources to improving the performance of its older reactors. Possibilities of reactor sales in Saskatchewan and New Brunswick were under discussion at the time of writing.

    A third waste incineration plant, which will conform to new United Kingdom emission standards is currently under construction at Tyseley in Birmingham. The plant will generate 25MW of electricity for 25,000 households by burning 350,000 t of municipal wastes per year. The site has been used for such energy from waste schemes since 1926. The new plant includes the latest air pollution abatement equipment designed to absorb mercury vapour and dioxins together with fabric filters. Other improvements at the Tyseley site include a new purpose built public waste disposal facility, clinical waste and animal carcass incineration and the recovery of 16,000t of ferrous metals per year for recycling. Because these waste products are incinerated it also therefore reduce`s Birmingham`s need for landfill sites. (UK)

    The article discusses Einstein's famous papers of 1905-his miraculous year-and deals with their physical and historical context as well as their fundamental impact on modern physics. It shows that the papers are not isolated, but connected with each other by Einstein's deep-seated conviction of physical atomism and his criticism of an ether. They are concerned with specific problems that can be characterized as 'borderline problems' since they go beyond the traditional divisions between mechanics, electrodynamics, and thermodynamics

    The technique of functional endoscopic sinus surgery (FESS) has been widely accepted and applied to inflammatory diseases of the paranasal sinuses with internationally reported results of this technique having been very good. Our objective was to find out outcome after FESS at our centre. Two hundred patients who had undergone FESS during a two year period with an average follow-up period of eleven months were evaluated subjectively regarding the outcome of their endoscopic sinus surgery. An overall subjective improvement of about 94% was documented, with improvement in specific symptoms such as headache, nasal congestion, change in sense of smell, nasal discharge and recurrent infections ranging from 52% to 97%. Our center reports a subjective improvement of symptoms following FESS compatible with results attained internationally. (author)

    Full Text Available The objective of this investigation was to establish the correlation between selected motor dimensions and personal dimension of neuroticism of children between seven and eleven years of age. The subject sample consisted of 92 schoolboys, attending the first five grades of the elementary school Kette-Murn in Ljubljana. Motor abilities were measured with a battery of 20 motor tasks (flexibility, speed, balance, strength and co-ordination and neuroticism with the Big Five Questionnaire. The association between variables was analysed with correlation analysis. Personal dimension of neuroticism showed high correlation with the tests of coordination and speed in case of the children in lower classes and with the motor tests of flexibility in case of the children in higher classes of primary school.

  2. Nuclear power: Year 2000

    International Nuclear Information System (INIS)

    Siegel, J.R.

    1984-01-01

    This paper offers a contrary view on the future of nuclear power in the U.S. Contrarian, in that it argues that it is quite possible that the installed U.S. nuclear capacity in the year 2000 will be in the range of 250GWe. This projection is based on the longer view - a 20-30 year picture - of the price trends of the fuels commercially available to make electricity. And on the belief that other projections of nuclear capacity for the year 2000, while generally acknowledging the need to add significant amounts of new electricity capacity, are essentially discounting nuclear power. And thus, are ignoring fundamental economics. The logic for the projected 250 GWe follows: The demand for electricity is continuing to grow, albeit at a slower rate than that experienced prior to 1973; The excess generating capacity in the construction pipeline, which developed during the 1970s as economic growth rates came in at half the projections made in 1973, has been worked off; in fact, the pendulum has swung past the mid-point; U.S. utilities need to order an additional 200-350 GWe of capacity for service between 1992 and 2000; The real capital costs of plants, particularly nuclear plants, ordered in the 1980s will be less than that being completed today, as this new plant will be completed on a more expedient basis for reliability reasons, and built in an improved financial climate for utilities; Owing primarily to more favorable economics, but also to environmental considerations, at least half of new generating capacity will be nuclear

    The astonishing range of plants and animals of Central America's 7 countries (Guatemala, Belize, Honduras, El Salvador, Nicaragua, Costa Rica and Panama) is disappearing, as 60% of its forests have been cut for lumber and firewood as well as for cotton, cattle, or subsistence crops. Up to 5 million Mayans lived sustainably for thousands of years in an area now being destroyed by a few hundred thousand inhabitants. The Spanish colonization that started 500 years ago was concentrated in Panama, Nicaragua, and Guatemala. The majority of the English-speaking country of Belize are descended from the black slave population whose culture spread down the coast to Central America. Panama's service economy is based on the Panama Canal and trade and finance. Costa Rica benefits from a tourist industry based on its natural beauty, however, it also has the highest rate of deforestation and its fast population growth could jeopardize earlier social and economic progress. In El Salvador and Guatemala long periods of civil conflict have taken their toll on the economy and the environment. El Salvador has a mountainous territory and limited natural resources and industrialization, while the best land is in the hands of a few families. Honduras and Nicaragua retain the highest proportion of forest cover of the countries in the region, despite Nicaragua's years of tyranny, then revolution and the Contra war, and Honduras's own turmoils. Belize has achieved some stability, and is now strengthening its Central American links. Its coral reefs and coastal areas offer potential for sustainable development through fishing and tourism. Central American countries face the challenges of their fragile environments and major social problems.

    Wilhelm Conrad Roentgen, as was his custom, was working alone in his laboratory on Friday, November 8. 1895, when he first made a discovery that would have an enormous impact on physical and medical science and, indeed, upon all mankind. Let us have a short look on the personal record of Roentgen. His discovery of X-Ray and its applications in various areas has led to the need for radiation protection against its harmful effects. Later on a significant amount of publications from ICRP, ICRU, NCRP, UNSCEAR and IAEA giving new directions, directives, guidelines and recommendations for Radiation Protection every year was produced

    At 3:42 a.m on July 28, 1976, the now infamous Tangshan earthquake struck that heavily industrialized city in eastern China killing, by official count, 240,000 people. During the first 2 years after the earthquake, estimates of casualties ranged from 650,000 to 800,000. Almost certainly the exact number will never be known. The earthquake was measured at magntiude 7.8, and intensities that registered XI on teh Modified Mercalli Intensity Scale occurred throughout the city of Tangshan.

    The PA profession is 50 years young. Practicing PAs and current students hail from several generational categories ranging from Builders to Generation Z. This article reviews how different generations may have experienced PA program expansion, professional identity, state licensing, and prescription delegation. The authors sampled a cohort of PA program applicants about their views on what evokes optimism and concern for the PA profession. These themes mirror the recently paved professional road, while posing the all-important question: What construction lies on the horizon?

    It is now one year since the accident which destroyed the fourth unit of the Chernobyl nuclear power station in the Ukrainian Soviet Socialist Republic. Its principal cause was a flagrant disregard by operating personnel of well-established operating rules and procedures, which placed Unit 4 in an unstable state. This booklet reviews some aspects of what had already been done before the accident, and what has taken place since. It describes, in particular, the Agency's programmes in the field of nuclear safety

    A rotator cuff tear is a relatively frequent cause of pain and restricted motion of the shoulder. Some orthopaedists believe that any attempt at rotator cuff reconstruction will fail. The aim of this paper is to present our experience with arthroscopic reconstruction of rotator cuff tears. Between January 1998 and December 2008, 319 patients with an early diagnosis of rotator cuff rupture were treated. The group included 67 women and 252 men, with an average age of 37 years (range, 24 to 71 years) at the time of surgery. The patients indicated for arthroscopic reconstruction had to show free motion of the shoulder, had a full thickness tear up to 3 cm in size in the sagittal plane and a Patte stage 2 tear in the frontal plane at the maximum. The outcome of surgery was evaluated at one year of follow-up and included the patient's self-assessment, modified UCLA score and incidence of complications. The probability of failure was calculated as an odds ratio of an implant failure to failure of the other implants and the probability of repeat surgery in a given implant was calculated as a relative risk in relation to the other implants. The average operative time was 52 minutes (range, 25 to 85); the average UCLA score increased from 10 to 31 points (pRC anchors had the odds ratio for mechanical failure equal to 0.55 (95 % CI, 0.25 to 1.24) and the relative risk of repeat surgery equal to 0.41 (95% CI, 0.12 to 1.43). In addition, 18 complications were recorded. The frequency of deep wound infection was 0.7% (2/319). Six patients (2.1%) required repeat surgery for symptomatic bursitis and adhesive capsulitis. A recent meta-analysis has found no significant difference between the results of surgical rotator cuff reconstruction and its conservative treatment. We do not support this view but present here evidence that, when certain conditions are fulfilled, arthroscopic reconstruction can produce a very good clinical outcome.

    Cereal fields are central to balancing food production and environmental health in the face of climate change. Within them, invertebrates provide key ecosystem services. Using 42 years of monitoring data collected in southern England, we investigated the sensitivity and resilience of invertebrates in cereal fields to extreme weather events and examined the effect of long-term changes in temperature, rainfall and pesticide use on invertebrate abundance. Of the 26 invertebrate groups examined, eleven proved sensitive to extreme weather events. Average abundance increased in hot/dry years and decreased in cold/wet years for Araneae, Cicadellidae, adult Heteroptera, Thysanoptera, Braconidae, Enicmus and Lathridiidae. The average abundance of Delphacidae, Cryptophagidae and Mycetophilidae increased in both hot/dry and cold/wet years relative to other years. The abundance of all 10 groups usually returned to their long-term trend within a year after the extreme event. For five of them, sensitivity to cold/wet events was lowest (translating into higher abundances) at locations with a westerly aspect. Some long-term trends in invertebrate abundance correlated with temperature and rainfall, indicating that climate change may affect them. However, pesticide use was more important in explaining the trends, suggesting that reduced pesticide use would mitigate the effects of climate change. © 2015 John Wiley & Sons Ltd.

    Ten years ago, on 25 January 1983, the discovery of the W particle at CERN's proton-antiproton collider was announced to the world. The W, the electrically charged carrier of the weak nuclear force, had been predicted 24 years earlier in the classic formulations of modern weak interaction theory by Feynman and Gell- Mann and by Marshak and Sudarshan, and went on to play an important role in the subsequent electroweak unification of electromagnetism and the weak nuclear force. Following the discovery of the neutral current at CERN in 1973, it became clear that the W was an extremely heavy particle, some 80 times heavier than the proton, too heavy to be detected by any accelerator in operation at the time. Pushed by Carlo Rubbia, the CERN proton-antiproton collider was built to find the W and its electrically neutral companion, the Z. Collider operations at CERN in 1982 had been compressed into a two month run, from October to December. The teams at the big UA1 and UA2 experiments eagerly sifting through their 1982 data noticed the first signs of Ws. The initial candidate W events were announced in CERN seminars by Carlo Rubbia, for UA1, on 20 January 1983*, and the following day by Luigi Di Leila for UA2. As well as new science, these two seminars also set a trend for packing the CERN auditorium to overflowing

    Albert Einstein left Germany, the country of his birth, in 1894 and moved to Switzerland in 1895. He studied, worked and taught there, except for a year's stay in Prague, until1914. That year he returned to Germany, where he lived until his emigration to the United States in 1933. In 1905, while living with his wife Mileva and their first son Hans Albert in Bern and working as a technical expert at the Swiss Patent Office, he published his dissertation on the determination of molecular dimensions, his papers on Brownian Motion that helped to establish the Kinetic Theory of Heat and on the Photo-Electric Effect that validated the Quantum Theory of Light, and the two papers introducing the Special Theory of Relativity. How the young Einstein could help to lay the foundations of these theories while still working on his dissertation, holding a full-time job and helping to raise a family has evoked much discussion among his biographers. In this contribution, the extent to which living within Swiss society and culture could have made this feat possible will be examined. Old and recent photos of places in Switzerland where Einstein has lived and worked will be shown.

    This is an annual report, regularly issued by IPSN, that presents the ecological and health consequences of the Chernobyl Nuclear Accident. The present status of the Chernobyl Nuclear Plant, which Ukraine engaged to stop definitively in year 2000, is summarized. The only reactor unit now in operation is Chernobylsk-3 Reactor which poses two safety questions: evolution of cracks in part of the tubing and behaviour of the pressure tubes. Although, some improvements in the RBMK reactor types were introduced, problems remain that make IPSN to stress the requirement of stopping this NPP completely. In the contaminated territories surrounding Chernobyl incidence rate of infant thyroid cancers continues to grow, reaching values 10 to 100 times higher than the natural rate. In France the IPSN analyzed 60,000 records carried out in 17 sites during May 1986 and April 1989. It was estimated that the individual dose received during 60 years (1986-2046) by the inhabitants of the most affected zone (eastern France) is lower than 1.5 mSv, a value lower than 1% of the natural cosmic and telluric radioactivity exposure for the same period. For the persons assumed to live in the most attacked forests (from eastern France) and nourishing daily with venison and mushrooms the highest estimate is 1 mSv a year. Concerning the 'hot spots', identified in mountains by IPSN and CRIIRAD, the doses received by excursionists are around 0.015 mSv. For an average inhabitant of the country the dose piled up in the thyroid due to iodine-131 fallout is estimated to 0.5-2 mSv for an adult and 6.5-16 mSv for an infant. These doses are 100 to 1000 times lower than the ones to which the infants living in the neighbourhood of Chernobyl are exposed to. The contents of the report is displayed in the following six chapters: 1. Chernobyl in some figures; 2. The 'sarcophagus' and the reactors of the Chernobyl NPP; 3. Health consequences of the Chernobyl accident;. 4. The impact of Chernobyl fallout in France

    Do you remember punched paper tape? That’s how many INIS Member States sent their input to the database in the early years of the system. And you had to be careful with that tape; a torn paper tape was a nuisance. Of course the rolls of paper came by post, how else? And if it took two weeks to get a postal package with paper tape in it from somewhere in Asia to Vienna, so be it! Of course the more sophisticated INIS imputing centers used magnetic tapes. Yes, magnetic tapes were also shipped by post from the ends of the earth to Vienna and that also sometimes took weeks. I recall the total thesaurus revision that we undertook in 1971. INIS had taken over the nuclear terminology contained in the thesaurus of the ENDS system (European Nuclear Documentation System of the European Community) but soon decided on a total revision, total in the sense that we decided to revise both the terminological content of the thesaurus AND the structure (interrelationships) that was given to the terminology. Who were the “we” who carried out the revision? Staff at the national INIS centres of Czechoslovakia (as it was at the time), France, the U.S.A. and staff at the University of California in Berkley, California, plus of course the INIS staff in Vienna. Magnetic tapes were naturally the support used for the exchange of data. Can you imagine the crisscrossing of tapes around the globe during that one year of work? Almost incredible by today’s standards, where the tip of a key will send immeasurably vaster quantities of data anywhere on earth within a fraction of a second! But apart from its technological aspects and the continuous developments that these were subjected to and from which the system profited, it was the human aspect of the system, that is, the people that made INIS work, that was so interesting, challenging and finally rewarding for all those involved. And here we must immediately stress that what made the system such a success over these past 45 years, was

    Inhaled drugs are deposited directly in the respiratory tract. They therefore achieve higher concentrations with faster onset of action and fewer side effects than when used systemically. Nebulized drugs are mainly recommended for patients that require high doses of bronchodilators, when they need to inhale drugs that only exist in this form (antibiotics or dornase alfa) or when they are unable to use other inhalation devices. Technological development in recent years has led to new devices that optimize pulmonary deposits and reduce the time needed for treatment. In this review we focus solely on drugs currently used, or under investigation, for nebulization in adult patients; basically bronchodilators, inhaled steroids, antibiotics, antifungals, mucolytics and others such as anticoagulants, prostanoids and lidocaine.

    In 1895, exactly one hundred years, ago, a chance discovery in Wurzburg, Germany, marked the dawn of a new science - atomic physics. Other discoveries and new insights followed quickly. Apart from interruptions for two World Wars, this rapid succession of breakthroughs continued for 88 years. A new series of occasional articles in the CERN Courier will look back to what was happening one century ago. In Wurzburg on 8 November 1895, Wilhelm Conrad Rôntgen became an immortal legend. Interested in the effects of ultra-violet radiation, he covered a cathode-ray discharge tube with black paper and darkened the room. With the glow from the tube hidden, Rôntgen was surprised to see a fluorescent screen two metres away light up. For several weeks, Rôntgen hid in his laboratory, finding out more about the mysterious penetrating 'X' rays, produced when the cathode rays hit the end of the discharge tube. Since the time of Faraday, the glow produced in an evacuated tube when an electric current was passed through had intrigued physicists and entertained the public. Nobody understood what these cathode rays were. William Crookes in the UK, who had narrowly missed making the Rôntgen discovery, surmised they were a new 'fourth state' of matter. Some scientists said the phenomena were due to radiation, others said particles. Also in 1895, a young physics student named Ernest Rutherford arrived in Britain from New Zealand with a scholarship for further study. The scholarship, awarded to a New Zealand student only once every few years, had initially been given to a young chemist, but who decided at the last minute to get married and stay in New Zealand. The scholarship passed to Rutherford, who, thanks to a change in regulations, was able to use it at the Cavendish Laboratory in Cambridge, under J.J. Thomson. In New Zealand, Rutherford had carried out experiments on radio telegraphy. He took his transmitter to Britain and at Cambridge continued his pioneer

    Any discussion of the nuclear-proliferation regime in the post-Cold War era, its present role and expected function in the future must take into account the outcome of the New York Non-proliferation Treaty Review Conference held in 1995, and the four factors that shaped the twentieth century: fascism and communism, nuclear energy and environmental concerns, as well as the interaction between them. none of the factors can be handled within the boundaries of a single state. After fifty years of nuclear competition both for military and energy generation purposes, international conferences on disarmament, Non-proliferation Treaty, Comprehensive Test Ban Treaty, START negotiations and agreements, there are still remaining nuclear issues. Population growth, energy demands and supplies, all related to global environmental changes must be taken into account

    The steps that Enbridge Consumer Gas Company has taken to prepare for year 2000 were highlighted in a series of overhead viewgraphs which accompanied this presentation. The company's Y2K program was initiated early in 1998 with an initial assessment of the true magnitude of the problem. The transportation and distribution divisions of the company are running separate but coordinated programs. The methodology is to perform an inventory of all components, conduct risk assessments and to determine a compliance strategy to remediate any problems so that all critical systems can be Y2K ready by June, 1999. The second part of this presentation reviewed the company's business continuity planning.

    Full Text Available Orbital - The Electronic Journal of Chemistry is entering its 4th year of existence which is a reason to celebrate. A great work has been devoted to preserve a scientific journal of international reputation. This work was not always without mistakes or any trouble. However, these very adversities stimulate additional efforts in order to overcome our errors and, continuing with our serious proposal of editing a journal which scientists from all over the world can submit online their original works manuscripts to be published in peer review and open-access style. Beginning this year, Orbital was classified by the Chemistry Coordination Area on the B5 rank of CAPES Qualis (Brazil and, leveled as B4 by Coordination Areas of Materials and Engineering II. These important details demonstrate that Orbital is progressively attaining the acknowledgment of the Brazilian scientific community. The recognition by CAPES Qualis is crucial as the system evaluates the generation of knowledge in the Brazilian universities and the method by which this same knowledge disseminated to society. Not all these were possible without endeavoring of editors and volunteer assistance of advisors from several national and international institutions. Recently, the young Professors Kleber Thiago de Oliveira (UFSCAR, Grégoire Demetz (USP-RP and Amilcar Machulek Júnior (UFMS have joined us to share the idea and philosophy of Orbital by accepting our invitation to be associated editors. The tasks and challenges are enormous and, we are sure that new participants will support us on the way to achieve indexation in new Databases systems as SCOPUS, ISI and Scielo. Consequently, the international success of this electronic journal will be assured. We sincerely hope that in the academic Brazilian scenario, Orbital can figure as a solid bridge to interchange real creative science that is happening in various locations around the world.

    CERN, the European organization for nuclear research, has just celebrated its fifty years of existence. Its first goal was to counterbalance the migration of physics scientists towards the USA by the creation of a physics laboratory gathering scientists from the different European countries. Today, the CERN's mission has changed and has overcome all the expectations of its founders. In 2008, it will become, with the LHC (Large Hadron Collider), the biggest particle accelerator in the world. The CERN employs about 3000 physicists, engineers, technicians and workers. There is also 6500 people from 80 different countries who use the CERN's facilities during the year. The CERN is controlled by 20 European member states and 6 observer countries, and 20 non-member countries participate to the programs in progress. The CERN's power comes from its international and cosmopolitan spirit. The whole most famous physicists of the world can work together for the progress of science and for a better understanding of matter, of its interactions and of our universe. Two Nobel prices of physics come from the CERN: C. Rubbia and S. Van der Meer in 1983 for the discovery of W + , W - and Z 0 bosons, and G. Charpak for the development of particle detectors. One can foresee that the LHC will allow new scientific achievements, like for instance, during experiments for the quest of the famous Higgs boson. It is important also to mention that the CERN has been at the origin of several technological innovations in all technical and engineering domains in the framework of its fundamental physics researches.

    Since the first course of instruction twenty-five years ago 2085 foremen of power plants and district heating systems have by now received their certificates of a Chamber of Commerce and Industry. They are acting as unit operators and shift foremen and enjoy esteem and respect in their plants. Moreover, 3232 power plant operators have meanwhile finished their education and received the certificates for power plant operators from the 'KRAFTWERKSSCHULE E.V.' (power plant school). Power plant foremen and operators have proved in practice; their education will also in future be an essential part of the acitvities of the 'Kraftwerksschule e.V.'. With the peaceful utilization of nuclear energy new tasks have arisen to the 'Kraftwerksschule e.V.' They satisfied this development and and are since 1969 also educating nuclear power plant foremen. As the profound training in nuclear reactors themselves is only possible with a lot of reservations, the 'Kraftwerksschule e.V.' began in 1974 to build a nuclear power plant simulator center. One simulator each for nuclear power plants with pressurized water reactors and boiling water reactors have been available for four years. Operators of nuclear power plants who already have profound theoretical and practical knowledge are by this means receiving a complementary education on the dynamic operation behaviour of the plant and they learn to judge operating orders and to control the process with a high degree of safety and availability by means of performance-directed control measures. The good experiences made since 1978 with the use of simulators in the nuclear education have led to the decision to build in addition a simulator for fossil-fired power plants. Late in 1981 the orders for delivery of the simulator hardware and software were placed. The simulator will be available for primary and advanced training by the end of 1984. (orig./GL) [de

    This report provides summary results of the Calendar Year (CY) 1994 As Low As Reasonably Achievable (ALARA) Program performance at the Pacific Northwest Laboratory (PNL). This report includes data regarding performance in the area of personnel exposures to radiation, skin contaminations, control of contaminated areas, minimization of radioactive waste, and control of radioactive releases. In CY 1994: (1) The collective total effective dose equivalent to PNL employees during 1994 was 55 person-rem. The Field Dosimetry Services of the Radiological Control Department, Technical Support Section, projected that no PNL employee's dose would exceed 2 rem based on dosimeters processed during the year; no worker actually exceeded the projection-by the end of CY 1994. The maximum dose to any individual was 1.11 rem. (2) There were 34 instances of skin and personal-clothing contamination events for PNL employees during 1994. Eighteen of these contamination events occurred at the 324 Building; eleven occurred at the 325 Building; two occurred in the 327 Building; one occurred in the 326 Building; one occurred in the 3708 Building; and one occurred in the RTL Building. (3) PNL facilities contained 12 Airborne Radioactivity Areas, and 60 Contamination Areas and High Contamination Areas. The area of the Airborne Radioactivity Areas was 383 m 2 (4125 ft 2 ). The area of the Contamination Areas was 5290 m 2 (56,947 ft 2 ). The area of the High Contamination Areas was 266 m 2 (2863 ft 2 ). (4) PNL disposed of 10.5 m 3 (371 ft 3 ) of compacted low level waste. Also disposed was 423 m 3 (14,949 ft 3 ) of noncompacted low level and mixed waste that was not subject to volume reduction. The total radioactivity of the disposed waste was 1217 Ci. (5) PNL facilities released 165.2 Ci of noble gas, 3.0E-5 Ci of airborne particulate radioactive material, and 12.2 Ci of tritium to the environment

    Full text: On May 12, Hans J. Specht, Scientific Director of the Geseilschaft fur Schwerionenforschung (GSI), welcomed an audience of more than 500 to celebrate the 25th anniversary of the Darmstadt heavy ion research Laboratory. Warm greetings and best wishes from Jürgen Ruttgers, Federal Minister for Education, Science, Research and Technology were presented by Hartmut Grubei, Chairman of the GSI Board. The Hessian Minister for Science and Art, Christine Hohmann-Dennhardt, pointed out that the promotion of various fields of research cannot be judged only by the expected return for everyday life. Joachim Treusch, the Chairman of the Association of National Research Centres, went further by stating that basic research, driven by curiosity and not aiming at short term applications, is a necessity. Darmstadt Mayor Peter Benz expressed his pride in having such a prestigious Laboratory in the city and looked forward to a new element named after it. CERN Director General Chris Llewellyn Smith underlined the growing importance of international and inter-regional scientific collaboration and paid tribute to the role of German physicists in general and GSI in particular in CERN's work. GSI is a major partner in the international lead ion programme at CERN which came into operation last year, a scientific and technological success which provides a useful role model for future international partnerships. After pointing to interesting parallels between the two Laboratories - both basing new projects on existing facilities, and both serving large user communities - he thanked GSI for its valuable contributions to CERN. Highlights from the 25 years of GSI were summarized in a talk by Dirk Schwalm, Managing Director of the Max Planck Institute for Nuclear Physics in Heidelberg. Among other points he presented the unique accelerator facility and the discovery of the five heaviest elements. He stated that many dreams from the founding period of GSI had become a reality, and

    On July 1st of twenty years ago we launched the first issue of JHEP. It was a real challenge to try the adventure of a scientific journal thought and managed by scientists, independent of private or institutional publishers. The idea was that physicists who were performing the work, writing the papers, and refereeing those of their peers, could also edit them in an electronic format. Thus, at a limited cost which could be handled by academic or scientific institutions, giving open access to the published information, and avoiding the heavy burden at that time placed on our libraries. In order to avoid the failure that - as we well remember was predicted to us by publishing companies and institutions, we needed the active support of the scientific community. A support in collaborating to the scrutiny of papers and scientific policies but, mainly, in sending to us their good papers. We contacted in that sense several of our most active and renowned colleagues, restricting of course to our high energy physics field. We received many enthusiastic responses as can be specifically seen from the papers that appear in the first issues of the journal, as well as the respected names listed in the advisory and in the editorial boards featuring in the opening page of the first issue of JHEP attached to this letter. We were optimists, but perhaps not as much as to foresee the success of the journal, which, in his first 20 years, turned out to be one of the most (if not the most) prestigious one in our field. Success for which --- as first project chairman and executive editor - we must essentially thank the scientific community who supported JHEP by considering it ''their journal'', as was our intention from the start. In this occasion we would like to recall the important contribution of Marco Fabbrichesi who designed the software on which the journal is based, and the technical personnel who implemented it and made it work. It is our pleasure to mention

    2014-10-01

    The TraumaRegister DGU(®) organisational and technical development has undergone an evolution process, which started 20 years ago. Currently, the management of the registry is under the management of the "AUC - Academy for Trauma Surgery" (infrastructure) and the "Sektion NIS" (scientific responsibility). The aim of the registry was to establish an inter-hospital quality assessment tool with the option to use the increasing database for scientific evaluations of acute care. Year after year and most recently with the obligatory participation of certified hospitals the number of participating hospitals has grown as well as the registered cases per annum. Recently, even hospitals from other countries joined the registry too. Starting with six German hospitals and 260 cases in 1993, 20 years later more than 600 hospitals from eleven countries deliver over 30,000 trauma cases per year resulting in over 150,000 reported cases until 2013. In this article a historical perspective is presented of the evolution and current status of the TraumaRegister DGU(®). Copyright © 2014 Elsevier Ltd. All rights reserved.

    After completing her university studies in Italy, where it was not all that rare to come across female physicists, Maria Fidecaro arrived at CERN in 1956. Although men were certainly in the majority, they were all just colleagues and gender was irrelevant.    Giuseppe and Maria Fidecaro in 1963, surrounded by spark chambers, inside the detector for the experiment on the decay of a rho meson into a pi meson and a photon. Maria Fidecaro is no stranger to CERN and the field of research, having watched them develop over many years. "In the early days we worked in small teams of no more than two or three people", she recalls. "As in Italy, I was not the only woman involved in research at CERN. Men and women alike, our common goal was to understand physics and conduct experiments." Clearly, juggling an exciting job and looking after a family of four children didn't make for an easy life.

    This publication proposes an overview of the situation in Fukushima (in the plant and in its region), 5 years after the accident. As far as the plant is concerned, several issues are addressed: the withdrawal of fuel from decay pools, the management of contaminated waters, and the situation of reactors 1, 2 and 3. The radiological impact for operators is discussed in terms of radioactivity level, of occurrence of leukaemia, and of storage of radioactive wastes. The next part comments the slow return of populations and the recovery of agriculture, notably with respect to decontamination advances, and to waste management. Current perspectives for the Japanese nuclear industry are then addressed: creation of a new and stronger safety authority, and situation of the various other reactors (some are planned to be restarted, some will be dismantled, and new reactors are still being built). The last part addresses the rehabilitation of areas devastated by the tsunami, with temporary housing, urban planning comprising possibilities for the population to quickly find a shelter, and works on the coast for a better protection against tsunamis

    The legal dilemma that the year 2000 (Y2K) problem presents with regard to disclosure requirements is examined. In particular, this paper reviews the complexities involved for customers, suppliers and business partners to communicate about Y2K issues. The review prominently features the many levels of statutory, regulatory and legal overlay that must be considered before any communication takes place . One of the major barriers to disclosure is the threat that any statements made by one company or individual to another may give rise to various forms of liability, including limitation, defamation, misrepresentation, detrimental reliance, collateral contracts and warranties or representations. The paper also describes recent Canadian and U.S. Y2K disclosure requirements for public companies. While the legislation is intended to promote the voluntary sharing of Y2K information, it also sets out conditions limiting the extent to which Y2K statements can be used as the basis for liability. Canadian regulatory bodies also have several policies in effect that compel issuers of new securities to emphasize uncertainties which are likely to be factors in Y2K, and public companies to discuss and analyze risks, events and uncertainties within the management discussion and analysis section of their annual reports that would cause reported financial information to be not necessarily indicative of future operating results or conditions, should those uncertainties materialize. 8 refs.

Earlier this year, ESA turned 50, and last week it was the turn of the Abdus Salam International Centre for Theoretical Physics, ICTP, to blow out its 50 candles. I had the pleasure to be there for the occasion, and to take part in the first day of a four-day scientific celebration in which the true value of ICTP came to the fore.   Nobel Prize winning Pakistani physicist Abdus Salam established the ICTP in 1964, and went on to become its first director. The Centre’s mission was and remains to foster the development of international scientific cooperation and to promote scientific excellence with an emphasis on the developing world. Established outside Trieste, Italy, and operated under a tripartite agreement between the Italian government, the IAEA and UNESCO, the ICTP has proven itself true to that mandate and become a driving force for advancing scientific expertise around the globe....

    The Consortium for Risk Evaluation with Stakeholder Participation (CRESP) is a university-based consortium led by the Environmental and Occupational Health Sciences Institute (EOHSI) in New Jersey and the School of Public Health and Community Medicine of the University of Washington (UW) in Seattle. Designed to be an independent, outside integrating institution on risk, CRESP was selected in DOE's 1994 Notice of Proposed Interest competition and awarded a five-year cooperative agreement on March 13, 1995. CRESP's mission is to inform protective and cost-effective cleanup and enhance stakeholder understanding of the nation's nuclear weapons production waste sites by improving the scientific and technical basis of environmental management decisions. Eight separate task groups, drawn from the two universities, have been established to organize research and operations for CRESP. One senior researcher from one of the two schools directs the overall CRESP effort for that task group. Each university is currently focusing its site-specific research on issues and concerns raised at either Hanford or Savannah River. CRESP's Independent Peer Review group, peer reviews CRESP's work and has agreed to provide a review of major risk-evaluation processes within Environmental Management at DOE

    As reported in our previous issue (page 27), on 28 February Volker Soergel stepped down after serving as Chairman of the Board of the DESY Laboratory in Hamburg since January 1981, when the previous chairman, Herwig Schopper, moved to become Director General of CERN. DESY is now headed by Bjorn Wiik. During the twelve years of Soergel's mandate, DESY substantially evolved and progressed. Dominating the landscape was the big HERA electron-proton collider - the world's first - proposed, approved, constructed and commissioned under Soergel's leadership. As well as pioneering electron-proton collisions, HERA also broke new ground in international collaboration. At the approval of the project by the German government, it had already been made clear that both the machine and its experiments had to be built with full international cooperation, using material contributions from foreign institutes. With the difficult task of transforming these requirements into hard reality, Volker Soergel succeeded brilliantly. The 'HERA model', with interested countries pledging contributions in equipment and/or manpower, established a new route to major project involvement. For HERA, the substantial Italian contribution, organized by Antonino Zichichi, was vital to the success of the project

    The European Coordination Action on HELio- and ASteroseismology (HELAS) has completed its fourth and final year of initial funding by the European Commission. Set up as a network which combines solar and stellar physics communities in the important and vigorously evolving field of seismology, HELAS has been able to coordinate the efforts of European astronomers with remarkable success. Four large international conferences including the HELAS-IV conference on Lanzarote as well as many workshops were organized with a substantial contribution from HELAS. About a dozen workshops, addressing specialized questions in global and local helioseismology and asteroseismology were entirely organized by HELAS. Data analysis tools to prepare the European communities for the upcoming influx of data from new missions have been prepared, tested and demonstrated. Lecture notes and outreach material have been assembled and prepared for general access. As a result, HELAS has an important impact on the scientific output of the astrophysics seismology communities and significantly increased the visibility of European research in this field. This paper summarizes the activities and accomplishments of HELAS.

  1. One hundred years on..

    2014-01-01

    One hundred years on from the 'war to end all wars', the face of war has profoundly changed. Inter-State conflicts still exist, but are spatially limited; world war is no longer on the agenda. And if a major power is involved, conflict now has every chance of being both violent (given modern strike capabilities) and short (given the cost of strikes). At least three factors explain this shift, starting with the de-legitimising of war. The horrors of the world wars; a European edifice built on a rejection of war; a neo-pacifism born, in Europe, of wealth, ageing, and economic crisis; and finally, the delusions of the past twenty years, resulting from commitments 'that do not amount to war': all downgrade the war hypothesis. The second factor is the nuclear mortgage, which devalues escalation to extremes. The reality of the first industrial and total war created an initial wave of pacifism in the 1920's. Today, the prospect of unmanageable escalation, the hypothesis, beyond a certain level of violence, of a post-total war curbs different forms of aggression. The image of war remains useful for peace. The third is the relative pacification of relations between major powers in the post-Cold War era. It is yet to be called into question by the re-distribution of power promised by the emergence of new major actors, at either the regional or global level. These three factors must continually be re-appraised. The de-legitimising of war is a cultural phenomenon and can thus evolve, either in a certain climate (as the U.S. 'folly' after 9/11 demonstrates), or in the long term (with a re-evaluation of confrontations between 'sides'). A subsidiary issue concerns how Europe, which is largely unable to psychologically and materially deal with the war hypothesis, would react to a re-brutalization of the world. The nuclear mortgage depends on the viability of the system that manages both nuclear power-projection and non-proliferation. In this respect the negotiations with Iran are

  2. Expected years ever married

    Full Text Available Background: In the second half of the 20th century, remarkable marriage changes were seen: a great proportion of never married population, high average age at first marriage, and large variance in first marriage timing. Although it is theoretically possible to separate these three elements, disentangling them analytically remains a challenge. Objective: This study's goal is to answer the following questions: Which of the three effects, nonmarriage, delayed marriage, or expansion, has the most impact on nuptiality changes? How does the most influential factor differ by time periods, birth cohorts, and countries? Methods: To quantify nuptiality changes over time, we define the measure 'expected years ever married' (EYEM. We illustrate the use of EYEM, looking at time trends in 15 countries (six countries for cohort analysis and decompose these trends into three components: scale (the changes in the proportion of never married - nonmarriage, location (the changes in timing of first marriage - delayed marriage, and variance (the changes in the standard deviation of first marriage age - expansion. We used population counts by sex, age, and marital status from national statistical offices and the United Nations database. Results: Results show that delayed marriage is the most influential factor on period EYEM's changes, while nonmarriage has recently begun to contribute to the change in North and West Europe and Canada. Period and cohort analysis complement each other. Conclusions: This study introduces a new index of nuptiality and decomposes its change into the contribution of three components: scale, location, and variance. The decomposition steps presented here offer an open possibility for more elaborate parametric marriage models.

    This Energy & Environmental Research Center (EERC) Year 2 Biomass Utilization Final Technical Report summarizes multiple projects in biopower or bioenergy, transportation biofuels, and bioproducts. A prototype of a novel advanced power system, termed the high-temperature air furnace (HITAF), was tested for performance while converting biomass and coal blends to energy. Three biomass fuels--wood residue or hog fuel, corn stover, and switchgrass--and Wyoming subbituminous coal were acquired for combustion tests in the 3-million-Btu/hr system. Blend levels were 20% biomass--80% coal on a heat basis. Hog fuel was prepared for the upcoming combustion test by air-drying and processing through a hammer mill and screen. A K-Tron biomass feeder capable of operating in both gravimetric and volumetric modes was selected as the HITAF feed system. Two oxide dispersion-strengthened (ODS) alloys that would be used in the HITAF high-temperature heat exchanger were tested for slag corrosion rates. An alumina layer formed on one particular alloy, which was more corrosion-resistant than a chromia layer that formed on the other alloy. Research activities were completed in the development of an atmospheric pressure, fluidized-bed pyrolysis-type system called the controlled spontaneous reactor (CSR), which is used to process and condition biomass. Tree trimmings were physically and chemically altered by the CSR process, resulting in a fuel that was very suitable for feeding into a coal combustion or gasification system with little or no feed system modifications required. Experimental procedures were successful for producing hydrogen from biomass using the bacteria Thermotoga, a deep-ocean thermal vent organism. Analytical procedures for hydrogen were evaluated, a gas chromatography (GC) method was derived for measuring hydrogen yields, and adaptation culturing and protocols for mutagenesis were initiated to better develop strains that can use biomass cellulose.

    To describe the support needs of parents caring for a child with an intellectual disability in the first year of life. Parents of children with intellectual disabilities face significant challenges during the first year of their child's life which is an important developmental period not previously addressed in the literature. The provision of support by health professionals, particularly nurses and midwives, during this crucial period can impact on parental well-being and on the health and developmental outcomes of their children. However, parents often feel unsupported. The study used a qualitative descriptive methodology. Semi-structured interviews were conducted with parents of eleven children with an intellectual disability in Victoria, Australia, during 2014. Interviews were digitally recorded, transcribed verbatim and analysed using thematic data analysis. Three key areas of support need were identified to assist parents to provide effective care for their child with an intellectual disability in the first year of life: (1) emotional support as parents adjusted to their role of caring for a child with an intellectual disability; (2) information support as they embarked on a quest for knowledge; and (3) support to facilitate their connection to peer networks. The findings highlighted inconsistent provision of support for parents. This study informs health professionals about how to provide holistic, timely support to parents of children with intellectual disabilities in the first year of life. There is an urgent need to review how nurses and midwives can provide relevant support that is responsive to parents' needs. © 2016 John Wiley & Sons Ltd.

Besides that, participants' hearing thresholds were within normal limits and their verbal recognition in the dichotic test of digits was equal or superior to 95% of hits. All were submitted to the Gap in Noise test. The statistical analysis was performed by non-parametric tests with significance level of 0.05 (5%). the average of the gap thresholds was 5.05 ms, and the average percentage of correct answers was 71.70%. There was no significant statistical difference between the responses by age (eleven and twelve years), by ear (right and left), by gender (male and female). However, when comparing the tests, it was observed that the 1st test showed a higher percentage of identifications of gap, statistically significant than the 2nd test. in 78.27% of the population of this study, the gap thresholds were up to 5 ms, response recommended as normality reference for the age group searched.

    Eighty-six children diagnosed as child abuse and/or neglect were admitted to the Paediatric wards of the General Hospital, Kuala Lumpur during 1985 and 1986. Of these cases, 62 were of physical abuse, six of sexual abuse, one case of both physical and sexual abuse and 17 of neglect. There were 25 boys and 61 girls. Thirty-four of these children were Malays, 16 Chinese, 26 Indians, three mixed and seven illegal immigrants. Twenty-one were below the age of one year, 24 from one to four years, 25 from five to nine years and 16 were ten years and above. The abusers were mainly close members of the family. Of these children, 24 were sent back to their parents and 11 to their relatives home. Twenty-seven were taken into care by the Ministry of Social Welfare and the remaining seven children who were illegal immigrants, were deported with their parents. Only one child was successfully fostered. Eleven children were taken away from the hospital by their parents or guardians without the knowledge of the health staff. There were five deaths in the series.

Germany as a traditional coal country and as a land of energy transition can no longer avoid this debate. After all, the climate targets that have been adopted several times for 2030, 2040 and 2050 will ultimately mean the end of coal-fired power generation. In January 2016, Agora Energiewende presented a proposal with the eleven cornerstones for a coal consensus on how such an exit from coal-fired power generation could look like. We are concerned with a cross-party consensus that is broadly anchored in society, which gives all parties involved planning security and reliability and at the same time paves the way for a socially balanced and fairly structured transition to the new energy system. The impacts are particularly relevant for the brown coal regions concerned. In order to make the gradual phasing out of coal-fired power generation socially and economically compatible, special attention must be paid to open-cast brown coal mines and power plants as well as to regional structural change. This publication therefore takes a closer look at precisely these aspects. [German] Seit dem historischen Klimaabkommen von Paris ist klar: Die Energieversorgung wird von nun an weltweit unter der Praemisse der Dekarbonisierung diskutiert. Deutschland als traditionelles Kohleland und als Land der Energiewende kann dieser Debatte nicht laenger ausweichen. Denn die fuer 2030, 2040 und 2050 mehrfach beschlossenen Klimaziele bedeuten letztlich den Ausstieg aus der Kohleverstromung. Agora Energiewende hat im Januar 2016 mit den Elf Eckpunkten fuer einen Kohlekonsens einen Vorschlag vorgelegt, wie ein solcher Ausstieg aus der Kohleverstromung aussehen koennte. Uns geht es um einen parteiuebergreifenden, gesellschaftlich breit verankerten Konsens, der allen Beteiligten Planungssicherheit und Verlaesslichkeit gibt und

    We discuss the high skill of real-time forecasts of global surface temperature a year ahead issued by the UK Met Office, and their scientific background. Although this is a forecasting and not a formal attribution study, we show that the main instrumental global annual surface temperature data sets since 1891 are structured consistently with a set of five physical forcing factors except during and just after the second World War. Reconstructions use a multiple application of cross validated linear regression to minimise artificial skill allowing time-varying uncertainties in the contribution of each forcing factor to global temperature to be assessed. Mean cross validated reconstructions for the data sets have total correlations in the range 0.93-0.95,interannual correlations in the range 0.72-0.75 and root mean squared errors near 0.06oC, consistent with observational uncertainties.Three transient runs of the HadCM3 coupled model for 1888-2002 demonstrate quite similar reconstruction skill from similar forcing factors defined appropriately for the model, showing that skilful use of our technique is not confined to observations. The observed reconstructions show that the Atlantic Multidecadal Oscillation (AMO) likely contributed to the re-commencement of global warming between 1976 and 2010 and to global cooling observed immediately beforehand in 1965-1976. The slowing of global warming in the last decade is likely to be largely due to a phase-delayed response to the downturn in the solar cycle since 2001-2, with no net ENSO contribution. The much reduced trend in 2001-10 is similar in size to other weak decadal temperature trends observed since global warming resumed in the 1970s. The causes of variations in decadal trends can be mostly explained by variations in the strength of the forcing factors. Eleven real-time forecasts of global mean surface temperature for the year ahead for 2000-2010, based on broadly similar methods, provide an independent test of the

    The Spent Fuel Test - Climax (SFT-C) is located 420 m below surface in the Climax stock granite on the Nevada Test Site. The test is being conducted for the US Department of Energy (DOE) under the technical direction of the Lawrence Livermore National Laboratory (LLNL). Eleven canisters of spent nuclear reactor fuel were emplaced, and six electrical simulators were energized April to May 1980, thus initiating a test with a planned 3- to 5-year fuel storage phase. The SFT-C operational objective of demonstrating the feasibility of packaging, transporting, storing, and retrieving highly radioactive fuel assemblies in a safe and reliable manner has been met. Three exchanges of spent fuel between the SFT-C and a surface storage facility furthered this demonstration. Technical objectives of the test led to development of a technical measurements program, which is the subject of this and two previous interim reports. Geotechnical, seismological, and test status data have been recorded on a continuing basis for the first 2-1/2 years of the test on more than 900 channels. Data continue to be acquired from the test. Some data are now available for analysis and are presented here. Highlights of activities this year include analysis of fracture data obtained during site characterization, laboratory studies of radiation effects and drilling damage in Climax granite, improved calculations of near-field heat transfer and thermomechanical response, a ventilation effects study, and further development of the data acquisition and management systems

    Systematic data regarding early neurodevelopmental functioning in Smith-Magenis syndrome are limited. Eleven children with Smith-Magenis syndrome less than 3 years of age (mean, 19 months; range, 5-34 months) received prospective multidisciplinary assessments using standardized measures. The total sample scored in the moderately to severely delayed range in cognitive functioning, expressive language, and motor skills and exhibited generalized hypotonia, oral-motor abnormalities, and middle ear dysfunction. Socialization skills were average, and significantly higher than daily living, communication, and motor abilities, which were below average. Mean behavior ratings were in the nonautistic range. According to exploratory analyses, the toddler subgroup scored significantly lower than the infant subgroup in cognition, expressive language, and adaptive behavior, suggesting that the toddlers were more delayed than the infants relative to their respective peers. Infants aged approximately 1 year or younger exhibited cognitive, language, and motor skills that ranged from average to delayed, but with age-appropriate social skills and minimal maladaptive behaviors. At ages 2 to 3 years, the toddlers consistently exhibited cognitive, expressive language, adaptive behavior, and motor delays and mildly to moderately autistic behaviors. Combining age groups in studies may mask developmental and behavioral differences. Increased knowledge of these early neurodevelopmental characteristics should facilitate diagnosis and appropriate intervention.

    Metabolomics technology has enabled an important method for the identification and quality control of Traditional Chinese Medical materials. In this study, we isolated metabolites from cultivated Dendrobium officinale and Dendrobium huoshanense stems of different growth years in the methanol/water phase and identified them using gas chromatography coupled with mass spectrometry (GC-MS). First, a metabolomics technology platform for Dendrobium was constructed. The metabolites in the Dendrobium methanol/water phase were mainly sugars and glycosides, amino acids, organic acids, alcohols. D. officinale and D. huoshanense and their growth years were distinguished by cluster analysis in combination with multivariate statistical analysis, including principal component analysis (PCA) and orthogonal partial least squares discriminant analysis (OPLS-DA). Eleven metabolites that contributed significantly to this differentiation were subjected to t-tests (PDendrobium species revealed that the polysaccharide content of D. huoshanense was higher than that of D. officinale, indicating that the D. huoshanense was of higher quality. Based on the accumulation of Dendrobium metabolites, the optimal harvest time for Dendrobium was in the third year. This initial metabolic profiling platform for Dendrobium provides an important foundation for the further study of secondary metabolites (pharmaceutical active ingredients) and metabolic pathways.
