    Standardized inspections of food premises are part of environmental health systems implemented worldwide. The food safety strategy for the 2004 Olympic Games included standardized inspections to ensure uniformity and consistency of procedures and effective electronic management of data. Inspections were carried out by 196 inspectors in the five Olympic cities: Athens, Thessalonica, Volos, Iraklio, and Patra. From January 2003 to September 2004, a total of 1,249 food premises were inspected. An unsatisfactory inspection result (C grade) was received by 347 (27.8%) food premises, a relatively satisfactory result (B grade) was received by 332 (26.6%), and a satisfactory result (A grade) was received by 570 (45.6%). About 16% of inspected premises did not hold a valid permit. Unsatisfactory inspection results were more frequent for premises located in the two largest Greek cities in comparison with the other smaller cities (relative risk = 1.95, 95% confidence interval [CI] = 1.36 to 2.80). Based on logistic regression analysis, unsatisfactory inspection results were positively associated with food premises that were not located on a ground floor (odds ratio [OR] = 2.56, 95% CI = 1.39 to 4.73) and negatively associated with application of hazard analysis critical control point (HACCP) principles (OR = 0.27, 95% CI = 0.10 to 0.71). Food hygiene education through formal training programs should be encouraged to improve compliance of food premises. Food premises located on hotel floors and serving buffet meals are at higher risk for unsatisfactory conditions. Businesses that implemented a HACCP system within their operations to ensure food safety operated under more hygienic conditions. Future inspections by Public Health Authorities should involve elements of audit after the legislation for the application of HACCP principles.

    BACKGROUND Some myopia patients with unsatisfactory corneas consider corneal refractive surgery for different reasons. Accelerated corneal collagen crosslinking (ACXL) is an effective method to enhance the resistance of the cornea. The present investigation was designed to evaluate the changes of biomechanical properties in patients with myopia and thin corneas after femtosecond-laser in situ keratomileusis (FS-LASIK) concurrent with ACXL. MATERIAL AND METHODS A prospective study was designed. A total of 22 eyes of 11 myopia astigmatism patients with unsatisfactory corneas were enrolled. The patients were assigned to femtosecond-laser in situ keratomileusis concurrent with accelerated corneal collagen crosslinking (FS-LASIK-ACXL). The follow-up duration was 24 months. Manifest refraction, uncorrected (UDVA), and corrected distance visual acuity (CDVA), ultra-high-speed camera (Corvis-ST), corneal topography, anterior segment OCT (AS-OCT), Pentacam, and endothelial cell density (ECD) were examined before and after the operation. The corneal biomechanical and refractive data was analyzed using SAS9.3. Data were analyzed through normal distribution test and variance of analysis. The difference was considered as statistically significant when pLASIK-ACXL operation. The values of first applanation length (A1L), the second applanation length (A2L), the first applanation velocity (A1V), the second applanation velocity (A2V), deformation amplitude (DA), highest concavity peak distance (PD), and radius of curvature at the time of highest concavity (HCR) did not show significant difference after the operation. CONCLUSIONS FS-LASIK-ACXL is an effective and safe surgery for improving visual acuity for myopic patients with thin corneas, and it does not increase the risk of iatrogenic keratectasia.

    universidades, sociedades científicas y organismos gubernamentales, que permitan cuantificar las secuelas de este tipo de cirugía para clasificarlas y ofrecer alternativas de solución a las mismas.A series of patients with unsatisfactory results after a breast augmentation surgery with silicone implants is presented in this report. The aim is to identify the most frequent problems and to offer alternatives for their solution. From an universal group of 230 patients with aesthetic breast augmentation surgery done from 2004 to 2009, a selective group of 15 patients is presented; out of these, 12 had a surgical procedure done for the first time by another medical team and 3 done by the first author of this paper. After medical evaluation 13 patients had a secondary breast augmentation surgery in order to correct the problems with satisfactory results one year postoperative. Nevertheless, 2 patients had breast stretch marks as first problem in the postoperative period which does not have a definitive solution by now. The possible reasons of the problems are: inadequate or not indicated line of access in 60 %; implant size was excessive in 12 patients (80 %, out of these, 10 patients requested implants with smaller size and 2 did not agree to get new implants; 2 patients (13.3 % suffered implant rupture before the first postoperative year and 1 patient had rupture after 25 years of the surgical procedure; in 12 patients (80 % there was asymptomatic capsular contracture grade I and II and grade III in 3 patients (20 %. There was no information about the manufacturer of the implants in 6 patients (40 % and 10 patients (66 % did not have any information about the importance of having a certificate of guarantee on the implants. We conclude that there is a lack of unified criteria to face the secondary problems after breast augmentation surgery using silicone implants, therefore it is necessary to encourage scientific studies by universities, professional societies and governmental

    To evaluate impact of a performance improvement (PI) plan implemented after initial analysis, comparing 7 gynecologists working in 2 clinics. From January to October 2005, unsatisfactory rates for gynecologists and clinics were calculated. A PI plan was instituted at the end of the first quarter of 2006. Unsatisfactory rates for each quarter of 2006 and the first quarter of 2007 were calculated. Poisson regression analyzed results. A total of 100 ThinPrep Pap smears initially deemed unsatisfactory underwent reprocessing and revaluation. The study's first part evaluated 2890 smears. Clinic unsatisfactory rates, 2.7% and 2.6%, were similar (p > 0.05). Gynecologists' unsatisfactory rates were 4.8-0.6%; differences between each of the highest 2 and lowest rates were significant (p improvement. Reprocessing ThinPrep smears is an important means of reducing unsatisfactory rates but should not be a substitute for attention to quality in sampling.

    Full Text Available Background Cervical cytology for uterine cervical cancer screening has transitioned from conventional smear (CS to liquid-based cytology (LBC, which has many advantages. The aim of this study was to compare the proportion of unsatisfactory specimens from CS versus LBC at multiple institutions including general hospitals and commercial laboratories. Methods Each participating institution provided a minimum of 500 Papanicolaou (Pap test results for analysis. Pap tests were classified according to the participating institution (commercial laboratory or general hospital and the processing method (CS, ThinPrep, SurePath, or CellPrep. The causes of unsatisfactory results were classified as technical problems, scant cellularity, or complete obscuring factors. Results A total of 38,956 Pap test results from eight general hospitals and three commercial laboratories were analyzed. The mean unsatisfactory rate of LBC was significantly lower than that of CS (1.26% and 3.31%, p = .018. In the LBC method, samples from general hospitals had lower unsatisfactory rates than those from commercial laboratories (0.65% vs 2.89%, p = .006. The reasons for unsatisfactory results were heterogeneous in CS. On the other hand, 66.2% of unsatisfactory results in LBC were due to the scant cellularity. Conclusions Unsatisfactory rate of cervical cancer screening test results varies according to the institution and the processing method. LBC has a significantly lower unsatisfactory rate than CS.

    Highlights: • The methodology of numerical simulation of 3D heat-flux visualization is proposed. • A full-scale model of prototype office for each influential factor was set up. • The simulation results were compared with the indoor occupant comfort levels. • The contrast of average temperature increase due to user behavior was presented. - Abstract: In areas of China that have hot summers and cold winters, the overall performance of HVAC systems in the poorly-insulated existing office buildings is generally not satisfactory, especially in extreme weather conditions. The reasons for the unsatisfactory indoor thermal environment were deduced, and to validate the findings, a methodology of numerical simulation for 3D heat-flux visualization was proposed. A full-scale model of a prototype office room was created, with representative working conditions for the characteristics of particular building. The results of the heat-flux visualization and temperature distribution showed that the overall effect was resulted from merged reasons, and that significance ranking of each reason varied when the outside environmental conditions changed. The simulation results were compared with the indoor occupant comfort levels of the volunteers who worked in the target room. Models of possible influential factors such as the outdoor temperature, opening or closing windows, and the effect of window shading devices (WSD) were set up. The influence of user behavior on indoor temperature in opening window, or not using WSD was proven to be significant in causing unfavorable indoor conditions. According to the visualized evaluation and analysis of the various factors, corresponding methods for both improving indoor thermal conditions and saving energy are proposed

    The incidence of anal carcinoma has risen in recent decades. Exfoliative cytology screening of selected high risk patients is performed in many centers. Unsatisfactory cytology results are frustrating to patients, clinicians, and laboratorians. The aim of this study is to ascertain outcomes of patients with non-diagnostic anal cytology. A retrospective review of anal cytology testing performed at the Cleveland Clinic between 01/01/2001 and 12/31/2015 was performed. All cases were received as liquid-based samples and processed as ThinPreps (Hologic, Marlborough, MA). Co-testing for HR-HPV DNA was performed using Hybrid Capture 2® (Qiagen, Germantown, MD) in the majority of patients. Of 1,276 ThinPrep anal cytology samples, 130 (10%) were deemed unsatisfactory. 77% of patients were HIV positive. 85% were males. Of the unsatisfactory cases, 116 (89%) were co-tested for HR-HPV DNA. Of those, 40 patients (34%) had a simultaneous positive HR-HPV DNA. Adequate follow up cytology within a one year and a two year period revealed that 18/130 (14%) and 26/130 (20%) of patients had ASC or SIL respectively. Histologic follow-up within one and two years showed 3 patients (2%) and 8 patients (6%) with HSIL or worse. High risk patients with unsatisfactory anal cytology are not "negative". At least one-third proved to be concomitantly HR-HPV DNA positive with one-fifth showing subsequent cytologic squamous abnormalities and with more than 5% being diagnosed with a high grade intraepithelial lesion within two years. Prompt repeat cytology and/or HR-HPV DNA is recommended for high risk patients with non-diagnostic cytology. © 2017 Wiley Periodicals, Inc.

    The Bethesda system (TBS) has been used for cervical cytological diagnosis in Japan since 2008. Evaluation of specimen adequacy is the most important aspect of quality assurance and for precise diagnosis in TBS. A systematic review and meta-analysis were carried out to assess the unsatisfactory specimen rate in the primary cervical cancer screening setting in Japan. Ovid Medline and Ichushi-Web databases were searched from inception through to May 2017. Prospective and retrospective studies that reported the proportion of unsatisfactory specimens in healthy asymptomatic Japanese women in a cervical cancer screening program were eligible for inclusion; 17 studies were included in the meta-analysis. The random-effects model meta-analysis calculated summary estimates of the unsatisfactory rate of 0.60% (95% confidence interval [CI], 0.18-1.96%; I 2 = 99%) for conventional cytology and 0.04% (95% CI, 0.00-0.35%; I 2 = 99%) for liquid-based cytology (LBC). However, comparative results between conventional and liquid-based cytology, based on four direct and nine comparative studies, showed no significant difference (summary odds ratio = 3.5 × 10 -2 favoring LBC [95% CI, 6.9 × 10 -4 -1.7]; I 2 = 98%). In the subgroup analyses and meta-regressions, use of non-cotton devices for conventional cytology and use of a particular platform for LBC were associated with lower unsatisfactory rates. Meta-regression also suggested chronological improvement in unsatisfactory rates for both tests. In Japanese cervical cancer screening programs, conventional cytology remains prevalent. Future research needs to focus on evaluating the impact of screening programs using LBC by comparing the accuracy, performance, and cost-effectiveness with conventional cytology in the Japanese population. © 2018 The Authors.

    Fernanda Rangel da Veiga

    Full Text Available CONTEXT AND OBJECTIVE: Cervical cancer is a serious public health problem in Brazil. For patients with unsatisfactory colposcopic examinations without visible lesions, but with cervical cytological tests suggesting high-grade squamous intraepithelial lesion (HSIL, the national recommendation is to repeat cervical cytological tests after three months. Our aim was to assess the prevalence of HSIL and cancer among patients with initial cervical cytological tests suggestive of HSIL but with unsatisfactory colposcopic examinations without visible lesions, in order to contribute towards the discussion regarding a more effective clinical approach that might diminish the likelihood of patient abandonment of follow-up before appropriate diagnosis and treatment. DESIGN AND SETTING: Cross-sectional study in Colposcopy Clinic of IFF/Fiocruz. METHOD: Patients admitted between December 1989 and April 2007 with cytological diagnoses of HSIL but with unsatisfactory colposcopic examinations without visible lesions underwent cervical cone biopsy. RESULTS: Sixty-five such patients were included, comprising 33.8% with HSIL and 4.6% with cancer, confirmed histologically. The other patients presented low-grade squamous intraepithelial lesion (26.1%, glandular dysplasia (1.5% and absence of disease (33.8%. CONCLUSION: The observed prevalence of cancer and HSIL does not seem to be enough to justify immediate referral for cone biopsies to investigate the cervical canal in these cases. The findings suggest that the recommendation of repeated cytological tests following an initial one with HSIL, among patients with unsatisfactory colposcopic examinations without visible lesions, is appropriate in our setting. Efforts are needed to ensure adherence to follow-up protocols in order to reduce the chances of losses.

    To perform a derivation study to determine in which subcompetencies marginal/unsatisfactory pediatric residents had the greatest deficits compared with their satisfactorily performing peers and which subcompetencies best discriminated between marginal/unsatisfactory and satisfactorily performing residents. Multi-institutional cohort study of all 21 milestones (rated on four or five levels) reported to the Accreditation Council for Graduate Medical Education, and global marginal/unsatisfactory versus satisfactory performance reported to the American Board of Pediatrics. Data were gathered in 2013-2014. For each level of training (postgraduate year [PGY] 1, 2, and 3), mean differences between milestone levels of residents with marginal/unsatisfactory and satisfactory performance adjusted for clustering by program and C-statistics (area under receiver operating characteristic curve) were calculated. A Bonferroni-corrected significance threshold of .0007963 was used to account for multiple comparisons. Milestone and overall performance evaluations for 1,704 pediatric residents in 41 programs were obtained. For PGY1s, two subcompetencies had almost a one-point difference in milestone levels between marginal/unsatisfactory and satisfactory trainees and outstanding discrimination (≥ 0.90): organize/prioritize (0.93; C-statistic: 0.91) and transfer of care (0.97; C-statistic: 0.90). The largest difference between marginal/unsatisfactory and satisfactory PGY2s was trustworthiness (0.78). The largest differences between marginal/unsatisfactory and satisfactory PGY3s were ethical behavior (1.17), incorporating feedback (1.03), and professionalization (0.96). For PGY2s and PGY3s, no subcompetencies had outstanding discrimination. Marginal/unsatisfactory pediatric residents had different subcompetency gaps at different training levels. While PGY1s may have global deficits, senior residents may have different performance deficiencies requiring individualized counseling and

    A method for psychosocial evaluation of potentially stressful or unsatisfactory situations in manual work was developed. It focuses on subjective responses regarding specific situations and is based on interactive worker assessment when viewing video recordings of oneself. The worker is first video-recorded during work. The video is then displayed on the computer terminal, and the filmed worker clicks on virtual controls on the screen whenever an unsatisfactory psychosocial situation appears; a window of questions regarding psychological demands, mental strain and job control is then opened. A library with pictorial information and comments on the selected situations is formed in the computer. The evaluation system, called PSIDAR, was applied in two case studies, one of manual materials handling in an automotive workshop and one of a group of workers producing and testing instrument panels. The findings indicate that PSIDAR can provide data that are useful in a participatory ergonomic process of change.

    Sauropterygians form the largest and most diverse group of ancient marine reptiles that lived throughout nearly the entire Mesozoic era (from 250 to 65 million years ago). Although thousands of specimens of this group have been collected around the world since the description of the first plesiosaur in 1821 (ref. 3), no direct evidence has been found to determine whether any sauropterygians came on shore to lay eggs (oviparity) like sea turtles, or gave birth in the water to live young (viviparity) as ichthyosaurs and mosasauroids (marine lizards) did. Viviparity has been proposed for plesiosaur, pachypleurosaur and nothosaur sauropterygians, but until now no concrete evidence has been advanced. Here we report two gravid specimens of Keichousaurus hui Young from the Middle Triassic of China. These exquisitely preserved specimens not only provide the first unequivocal evidence of reproductive mode and sexual dimorphism in sauropterygians, but also indicate that viviparity could have been expedited by the evolution of a movable pelvis in pachypleurosaurs. By extension, this has implications for the reproductive pattern of other sauropterygians and Mesozoic marine reptiles that possessed a movable pelvis.

    Clinical signs of malnutrition, starvation, cachexia and sarcopenia overlap, as they all imply muscle wasting to a various extent. However, the underlying mechanisms differ fundamentally and therefore distinction between these phenomena has therapeutic and prognostic implications. We aimed to determine whether dietitians in selected European countries have 'sufficient knowledge' regarding malnutrition, starvation, cachexia and sarcopenia, and use these terms in their daily clinical work. An anonymous online survey was performed among dietitians in Belgium, the Netherlands, Norway and Sweden. 'Sufficient knowledge' was defined as having mentioned at least two of the three common domains of malnutrition according to ESPEN definition of malnutrition (2011): 'nutritional balance', 'body composition' and 'functionality and clinical outcome', and a correct answer to three cases on starvation, cachexia and sarcopenia. Chi-square test was used to analyse differences in experience, work place and number of malnourished patients treated between dietitians with 'sufficient knowledge' vs. 'less sufficient knowledge'. 712/7186 responded to the questionnaire, of which data of 369 dietitians were included in the analysis (5%). The term 'malnutrition' is being used in clinical practice by 88% of the respondents. Starvation, cachexia and sarcopenia is being used by 3%, 30% and 12% respectively. The cases on starvation, cachexia and sarcopenia were correctly identified by 58%, 43% and 74% respectively. 13% of the respondents had 'sufficient knowledge'. 31% of the respondents identified all cases correctly. The proportion of respondents with 'sufficient knowledge' was significantly higher in those working in a hospital or in municipality (16%, P four European countries show that the percentage of dietitians with 'sufficient knowledge' regarding malnutrition, starvation, cachexia and sarcopenia is unsatisfactory (13%). The terms starvation, cachexia and sarcopenia are not often used

    The focus is on GAVE as an integral multi-actor process, as a collaboration process in which the parties have to find each other. The reason for this multi-actor approach is that the parties themselves have to realise the importance of sustainable energy. A multi-actor approach uses this crucial fact as the starting point. By means of the use of specific multi-actor methods and insights, it is possible during the collaboration process to develop a clear idea of the content of the joint path and the intended collaborative future, while paying specific attention to the individual roles of the players. Based on this, a well- considered and promising realisation path can be followed. The objective of this study is to illustrate - on the basis of two GAVE options - how the multi-actor approach can support the GAVE programme. In doing this, emphasis is placed on examples, the demonstration of added value of such an approach, and making recommendations for the future. Two experiments have been carried out on the basis of the Trinity approach. The Trinity approach is a set of methods specifically developed for supporting change processes which involve many parties (i.e. multi-actor processes). Trinity helps those involved to obtain a clear picture of both the route to be followed and the future situation to be aimed at. The term 'picture' must be understood literally: an important aspect of Trinity is the collaboration and communication with multi-actor models (also referred to as actorprints). By means of a diagram technique (figures and arrows) these models demonstrate the cohesion between the roles and activities of the various parties involved. The modelling process is instrumental in this; the actual result is that the image that is developed is formed and backed up by the participants in the process. Within these experiments, we have, so far, worked mainly in the shadow of the current GAVE process. A forceful participative use of the actor approach is

    Nonspecific ST-segment and T-wave (ST-T) changes represent one of the most prevalent electrocardiographic abnormalities in hypertensive patients. However, a limited number of studies have investigated the association between nonspecific ST-T changes and unsatisfactory blood pressure (BP) control in adults with hypertension.The study population comprised 15,038 hypertensive patients, who were selected from 20,702 participants in the China Stroke Primary Prevention Trial. The subjects were examined with electrocardiogram test at the initial visit in order to monitor baseline heart activity. According to the results of the electrocardiogram (defined by Minnesota coding), the subjects were divided into 2 groups: ST-T abnormal and ST-T normal. Unsatisfactory BP control was defined as systolic BP ≥140 mm Hg or diastolic BP ≥90 mm Hg following antihypertensive treatment during the 4.5-year follow-up period. Multivariate analysis was used to analyze the association between nonspecific ST-T abnormalities and unsatisfactory BP control.Nonspecific ST-T changes were common in hypertensive adults (approximately 8.5% in the study), and more prevalent in women (10.3%) and diabetic patients (13.9%). The unsatisfactory BP control rate was high in the total population (47.0%), notably in the ST-T abnormal group (55.5%). The nonspecific ST-T abnormal group exhibited a significantly greater rate of unsatisfactory BP control (odds ratio [OR] 1.20, 95% confidence interval [CI] [1.06, 1.36], P = 0.005]), independent of traditional risk factors, as demonstrated by multivariate regression analysis. Notable differences were further observed in male subjects (OR 1.51, 95% CI [1.17, 1.94], P = 0.002) and in patients with comorbid diabetes (OR 1.47, 95% CI [1.04, 2.07], P = 0.029).Greater rates of unsatisfactory BP control in hypertensive patients with electrocardiographic nonspecific ST-T abnormalities were observed, notably in the subcategories of the male subjects

    Complete perfusion limited to the liver is essential to the success of regional chemotherapy for hepatic malignancy. Thirty-three patients with unsatisfactory hepatic artery perfusion scintigrams after surgical placement of a pump and catheter system were evaluated with selective angiography (31 cases) or digital subtraction angiography (DSA) via the pump side port (six cases). The cause of the perfusion defect was hepatic artery thrombosis (14 cases), extrahepatic flow through collaterals (13 cases), misplaced catheter (three cases), short proper hepatic artery without adequate length for mixing (two cases), and undefined (one case). DSA findings were diagnostic in only two cases. Angiographic findings directed attempted correction in 22 of 33 cases

    This research is an extension of earlier studies that examined Assertiveness and Aggressiveness as potential moderators of verbal intentions. A sample of 127 women and 137 men participated in the survey which used random residential telephone numbers. Respondents ranged in age from 18 to 71 years (M=33.2, SD= 12.4), with men making up 51.9% of the total sample. Those respondents classified as having an Aggressive interaction style were least likely to have discussed their unsatisfactory service encounters. The nature of the verbal communications was negative for all four interaction styles investigated. Similar to previous findings, men and women were equally Assertive, but men were more likely to be Aggressive when engaging in marketplace interactions.

    The purpose of the present study was to extend the external validity of an earlier longitudinal study of school leavers by including participants from a representative sample of secondary schools. Questionnaires were administered annually to a sample of South Australian school leavers over a 10-year period. At Time 1 participants were in the last compulsory year of high school aged around 15 years and at Time 10 they were aged around 25 years. Results confirmed those from an earlier longitudinal study showing that the transition from school to satisfactory employment was associated with significant improvements in psychological well-being, whereas transition from school to unemployment or unsatisfactory employment showed no change in psychological well-being. The current findings extended the external validity of the earlier study because whereas participants in the earlier study were sampled from co-educational metropolitan public high schools, the current study included participants from every kind of high school: single sex as well as co-educational, rural as well as metropolitan, and private as well as public.

    Psychosocial stress and pain may relate to educational selection. At the end of primary school (International Standard Classification of Education: ISCED level 1) children are recommended for one of three performance-based lower secondary level types of school (ISCED level 2). The study examines the association of educational selection and other risk factors with pain in the upper back (UBP), lower back pain (LBP), peripheral (limb) pain (PP), and abdominal pain (AP). Teacher reports of unsatisfactory grades in mathematics, and official school-type recommendation are included as objective psychosocial risk factors. One hundred and ninety-two schoolchildren, aged between 10 and 13 from 11 classes of 7 schools in Switzerland participated in the cross-sectional study. In logistic regression analysis, predictor variables included age, sex, BMI, participation in sport, physical mobility, weight of satchel, hours of daily TV, video, and computer use, pupils' back pain reported by the mother and father, psychosocial strain, unsatisfactory grade in mathematics, and school-type recommendation. Analysis of pain drawings was highly reliable and revealed high prevalence rates of musculoskeletal pain in the last 4 weeks (UBP 15.3%, LBP 13:8%, PP 33.9%, AP 20.1%). Psychosocial risk factors were uniquely significant predictors of UBP (psychosocial strain), LBP (psychosocial strain, unsatisfactory grade in mathematics, school-type recommendation), and AP (school-type recommendation). In conclusion, selection in terms of educational school system was uniquely associated with LBP in schoolchildren. Stress caused by educational selection should be addressed in primary prevention of musculoskeletal pain in schoolchildren.

    For the last 15 years contract policy has been one of the top priorities of CERN staff, as expressed in successive surveys initiated by the Staff Association. In one’s professional life, having some forward vision of one’s career prospects is the key to loyalty and motivation. On the contrary, instability about the future is always at the root of anxiety, conflicts, or even health problems. A good employer must therefore balance the needs of the Company and those of its employees. CERN’s current contract policy, as described in the Administrative Circular No 2, states that staff members should first obtain a limited duration (LD) contract of up to five years. Then, if they want to stay in the Organization, staff members must apply, usually once a year, and before the end of their LD contract, for an indefinite contract (IC) post. All candidates for an IC post are considered by the Review Board for the award of indefinite contracts (Review Board) which will choose the most suita...

    Full Text Available Conjunctival injection and tearing with unilateral short lasting neuralgiform headache syndrome is called as SUNCT. Even though these headaches are reported seldomly, the prevalence is possibly higher than known. It is of importance to recognize these uncommon disorder, since its management differs from common primary headaches. Until today, it was reported to be treated with different types of drugs. We here reported a 30 years old male patient with normal neurological examination, blood examination and neuroimaging. Our patient gave no response to indomethacin, gabapentine and carbamazepine treatments. This case is an example of SUNCT case treated with steroid

    Femoral head and neck ostectomy (FHNO) is a salvage surgical procedure intended to eliminate hip joint laxity associated pain in the immature dog, or pain due to secondary osteoarthritis in the mature dog. The outcome of the procedure is associated with the size of the dog but the cause of a generally poorer outcome in larger breeds has not been determined. The objective of this study was to assess the long-term results of FHNO associated with unsatisfactory functional outcome by means of clinical examination and computed tomography (CT) scanning. Four large mixed breed dogs underwent FHNO in different veterinary clinics. Clinical and CT scanning evaluations were carried out long time after the procedures had been done. Hip pain, muscle atrophy, decreased range of motion and chronic lameness were observed at clinical examination. Extensive remodelling, unacceptable bone-on-bone contact with bony proliferation involving the femoral neck and acetabulum, but also excessive removal with bone lysis were observed by CT scanning. Revision osteotomy was performed in one dog. Deep gluteal muscle interposition was used, but no improvements were observed postoperatively. This is the first report on the evaluation of three-dimensional CT reconstructions of the late bone remodelling associated with poor clinical outcome in large dogs. The study shows that FHNO could lead to severe functional deficits in large breed dogs. An extensive follow-study is necessary to more accurately determine the frequency of such complications.

    Community-based advocacy services are important in enabling victims to escape domestic abuse and rebuild their lives. This study evaluated a domestic abuse service. Two phases of research were conducted following case-file analysis (n = 86): surveys (n = 22) and interviews (n = 12) with victims, and interviews with key individuals (n = 12) based in related statutory and community organizations. The findings revealed the holistic model of legal, practical, mental health-related, and advocacy components resulted in a range of benefits to victims and enhanced interagency partnership working. Core elements of a successful needs-led, victim-centered service could be distilled. © The Author(s) 2015.

    Objective: To determine the thyroid status of mother's of newborns with primary congenital hypothyroidism. Methodology: Thyroid function tests were carried out on 80 mothers of hypothyroid newborns and 80 mothers of non-hypothyroid newborns as control. Results: The mean difference of the tests revealed that mothers of congenitally hypothyroid infants had a lower triiodothyronine resin uptake (T3RU) concentrations compared with the control population. The higher value of free thyroxin index (FTI) in case group showed a tendency to significance. The proportional frequency distribution showed; T3RU and triiodothyronine (T3) had a significant difference, and FTI showed a tendency to significance. There were no significant differences between; thyroid-stimulating hormone (TSH), thyroxine (T4) and anti-thyroid peroxidase antibodies (anti-TPO) in two groups. Conclusions: These results indicated that at least some cases of primary congenital hypothyroidism were attributable to the maternal thyroid disease. Therefore, we recommend that each pregnant woman should be assessed for thyroid function in region with a high prevalence of thyroid disease. (author)

    Context. The Orion A molecular complex is a nearby (420 pc), very well studied stellar nursery that is believed to contain examples of triggered star formation. Aims: As part of the Herschel guaranteed time key programme CHESS, we present the discovery of a diffuse gas component in the foreground of the intermediate-mass protostar OMC-2 FIR 4, located in the Orion A region. Methods: Making use of the full HIFI spectrum of OMC-2 FIR 4 obtained in CHESS, we detected several ground-state lines from OH+, H2O+, HF, and CH+, all of them seen in absorption against the dust continuum emission of the protostar's envelope. We derived column densities for each species, as well as an upper limit to the column density of the undetected H3O+. In order to model and characterise the foreground cloud, we used the Meudon PDR code to run a homogeneous grid of models that spans a reasonable range of densities, visual extinctions, cosmic ray ionisation rates and far-ultraviolet (FUV) radiation fields, and studied the implications of adopting the Orion Nebula extinction properties instead of the standard interstellar medium ones. Results: The detected absorption lines peak at a velocity of 9 km s-1, which is blue-shifted by 2 km s-1 with respect to the systemic velocity of OMC-2 FIR 4 (VLSR = 11.4 km s-1). The results of our modelling indicate that the foreground cloud is composed of predominantly neutral diffuse gas (nH = 100 cm-3) and is heavily irradiated by an external source of FUV that most likely arises from the nearby Trapezium OB association. The cloud is 6 pc thick and bears many similarities with the so-called C+ interface between Orion-KL and the Trapezium cluster, 2 pc south of OMC-2 FIR 4. Conclusions: We conclude that the foreground cloud we detected is an extension of the C+ interface seen in the direction of Orion KL, and interpret it to be the remains of the parental cloud of OMC-1, which extends from OMC-1 up to OMC-2.

    Facing the increasing prevalence of gestational diabetes mellitus (GDM), this study aimed to evaluate the management of GDM and its association with adverse pregnancy outcomes. The data of 996 inpatients with GDM who terminated pregnancies in our hospital from January 2011 to December 2015 were collected. Treatments during pregnancy and the last hospital admission before delivery were analyzed. Pregnancy outcomes of the GDM patients were compared with 996 nondiabetic subjects matched by delivery year and gestational age. The association between fasting plasma glucose (FPG) and adverse pregnancy outcomes was examined by logistic regression analyses. The average prevalence of GDM over the 5 years was 4.4% (1330/30,191). Within the GDM patients, 42.8% (426/996) received dietary intervention, whereas 19.1% (190/996) received insulin treatment. Adverse outcomes were more likely to occur in patients with unsatisfactory control of blood glucose such as respiratory distress syndrome (RDS, χ 2 = 13.373, P < 0.01). Elevated FPG was identified as an independent risk factor for premature birth (odds ratio [OR] = 1.460, P < 0.001), neonatal care unit admission (OR = 1.284, P < 0.001), RDS (OR = 1.322, P = 0.001), and stillbirth (OR = 1.427, P < 0.001). Management of GDM in the real world of clinical practice was unsatisfactory, which might have contributed to adverse pregnancy outcomes.

    Results of thyroid biopsy determine whether thyroid nodule resection is appropriate and the extent of thyroid surgery. At our institution we use 20/22-gauge core biopsy (CBx) in conjunction with fine-needle aspiration (FNA) to decrease the number of passes and improve adequacy. Occasionally, both ultrasound (US)-guided FNA and CBx yield unsatisfactory specimens. To justify clinical recommendations for these unsatisfactory thyroid biopsies, we compare rates of malignancy at surgical resection for unsatisfactory biopsy results against definitive biopsy results. We retrospectively reviewed a database of 1979 patients who had a total of 2677 FNA and 663 CBx performed by experienced interventional radiologists under US guidance from 2003 to 2006 at a tertiary-care academic center. In 451 patients who had surgery following biopsy, Fisher's exact test was used to compare surgical malignancy rates between unsatisfactory and malignant biopsy cohorts as well as between unsatisfactory and benign biopsy cohorts. We defined statistical significance at P = 0.05. We reported an overall unsatisfactory thyroid biopsy rate of 3.7% (100/2677). A statistically significant higher rate of surgically proven malignancies was found in malignant biopsy patients compared to unsatisfactory biopsy patients (P = 0.0001). The incidence of surgically proven malignancy in unsatisfactory biopsy patients was not significantly different from that in benign biopsy patients (P = 0.8625). In conclusion, an extremely low incidence of malignancy was associated with both benign and unsatisfactory thyroid biopsy results. The difference in incidence between these two groups was not statistically significant. Therefore, patients with unsatisfactory biopsy specimens can be reassured and counseled accordingly.

    The Welsh Food Microbiological Forum "shopping basket" survey is a long running, structured surveillance program examining ready-to-eat food randomly sampled from the point of sale or service in Wales, United Kingdom. The annual unsatisfactory rates for selected indicators and pathogens for 1998 through 2008 were examined. All the annual unsatisfactory rates for the selected pathogens were <0.5%, and no pattern with the annual rate was observed. There was also no discernible trend observed for the annual rates of Listeria spp. (not moncytogenes), with all rates <0.5%. However, there was a trend observed for Esherichia coli, with a decrease in rate between 1998 and 2003, rapid in the first few years, and then a gradual increase in rate up to 2008. It was concluded that there was no discernible pattern to the annual unsatisfactory rates for Listeria spp. (not monocytogenes), L. monocytogenes, Staphylococcus aureus, and Bacillus cereus, but that a definite trend had been observed for E. coli.

    The Netherlands agency for energy and the environment (Novem) commissioned a consortium to carry out the ABC (Dutch abbreviation for Waste and Biomass Conversion) project in three separate studies: (A) a scenario study of the availability of biomass and waste for energy generation in the Netherlands; (B) a 'three-level assessment' of biomass availability on national, European and global levels; and (C) a scenario study of the feasibility / profitability of energy crops in the Netherlands. The results of the ABC project are published in two separate reports. This present report gives the results of the combined scenario study of availability (A) and the three-level assessment (B). The results of the energy crops study (C) are presented elsewhere. The goal of the present project is to gain insight into the current availability of biomass and waste flows for energy generation, and of the driving forces and constraints that can affect their availability up to the year 2020. First, it is examined whether the availability of biomass and waste is or could become problematic. This is an important aspect for market parties that want to invest in energy from biomass and biomass. Second, it is examined what additional policy measures the Dutch government would need to take to achieve the set policy goal of savings of fossil fuels. The combined scenario study of waste availability (in the Netherlands) and biomass availability (in the Netherlands, the European Union, and worldwide) for energy generation started off with a Definition Phase. In this phase, the project's framework and key issues were formulated and relevant sources of information were outlined. On the basis of these sources, a Quick Scan was carried out to map the existing information as well as any gaps in knowledge and uncertainties about the availability of biomass and waste. In the subsequent In-depth Phase the results of the Quick Scan were submitted to a number of national experts for comment

    During the First World War soldiers suffered from a wide range of debilitating nervous complaints as a result of the stresses and strains of modern warfare. These complaints--widely known as shell shock--were the subject of much medical-military debate during the war and became emblematic of the war and its sufferings afterwards. One hundred years after the war the diagnosis of PTSD has not resolved the issues initially raised by First World War shell shock. The stigma of mental illness remains strong and it is still difficult to commemorate and remember the mental wounds of war in a culture which tend to glory or glamorise military heroes.

    The purpose of this retrospective study was to analyze and compare the clinical and radiologic outcomes of fixed bearing ultracongruent (UC) insert total knee arthroplasty (TKA) and mobile bearing (MB) floating platform TKA using the navigation-assisted gap balancing technique with a minimum follow-up of five years. The study retrospectively enrolled 105 patients who received the UC type fixed bearing insert (group 1) and 95 patients who received the floating platform MB insert (group 2) during the period from August 2009 to June 2012. All surgery was performed using the navigation-assisted gap balancing technique. For strict assessment of gap measurements, the offset-type-force-controlled-spreader-system was used. Radiologic and clinical outcomes were assessed before operation and at the most recent follow-up using the Knee Society Score (KSS) and the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score. For statistical analysis, paired sample t tests were used. A p value less than 0.05 was considered significant. Although the radiologic alignments were satisfactory for both groups (99/105 [94%] cases were neutral for group 1 and 90/95 [94%] for group 2), the functional and total WOMAC scores were inferior in group 2 (p bearing exchange. The Kaplan-Meier survivorship rates for groups 1 and 2 at 77 months were 100.0 and 97.9%, respectively. Second-generation MB floating platform TKA cases did not have satisfactory outcomes. There were two cases of insert breakage, which required bearing exchange. Other patients who underwent surgery with second-generation MB floating platform were encouraged to avoid high knee flexion activities, resulting in lower clinical performance.

    Full Text Available Abstract Background In colorectal carcinoma, extensive gene promoter hypermethylation is called the CpG island methylator phenotype (CIMP. Explaining why studies on CIMP and survival yield conflicting results is essential. Most experiments to measure DNA methylation rely on the sodium bisulfite conversion of unmethylated cytosines into uracils. No study has evaluated the performance of bisulfite conversion and methylation levels from matched cryo-preserved and Formalin-Fixed Paraffin Embedded (FFPE samples using pyrosequencing. Methods Couples of matched cryo-preserved and FFPE samples from 40 colon adenocarcinomas were analyzed. Rates of bisulfite conversion and levels of methylation of LINE-1, MLH1 and MGMT markers were measured. Results For the reproducibility of bisulfite conversion, the mean of bisulfite-to-bisulfite standard deviation (SD was 1.3%. The mean of run-to-run SD of PCR/pyrosequencing was 0.9%. Of the 40 DNA couples, only 67.5%, 55.0%, and 57.5% of FFPE DNA were interpretable for LINE-1, MLH1, and MGMT markers, respectively, after the first analysis. On frozen samples the proportion of well converted samples was 95.0%, 97.4% and 87.2% respectively. For DNA showing a total bisulfite conversion, 8 couples (27.6% for LINE-1, 4 couples (15.4% for MLH1 and 8 couples (25.8% for MGMT displayed significant differences in methylation levels. Conclusions Frozen samples gave reproducible results for bisulfite conversion and reliable methylation levels. FFPE samples gave unsatisfactory and non reproducible bisulfite conversions leading to random results for methylation levels. The use of FFPE collections to assess DNA methylation by bisulfite methods must not be recommended. This can partly explain the conflicting results on the prognosis of CIMP colon cancers.

    Full Text Available Abstract Background Reduction of maternal mortality is a global priority particularly in developing countries including Ethiopia where maternal mortality ratio is one of the highest in the world. The key to reducing maternal mortality ratio and improving maternal health is increasing attendance by skilled health personnel throughout pregnancy and delivery. However, delivery service is significantly lower in Amhara Regional State, Ethiopia. Therefore, this study aimed to assess factors affecting institutional delivery service utilization among mothers who gave birth in the last 12 months in Sekela District, Amhara Region, Ethiopia. Methods Community-based cross-sectional study was conducted among mothers with birth in the last 12 months during August, 2010. Multistage sampling technique was used to select 371 participants. A pre tested and structured questionnaire was used to collect data. Bivariate and multivariate data analysis was performed using SPSS version 16.0 software. Results The study indicated that 12.1% of the mothers delivered in health facilities. Of 87.9% mothers who gave birth at home, 80.0% of them were assisted by family members and relatives. The common reasons for home delivery were closer attention from family members and relatives (60.9%, home delivery is usual practice (57.7%, unexpected labour (33.4%, not being sick or no problem at the time of delivery (21.6% and family influence (14.4%. Being urban resident (AOR [95% CI] = 4.6 [1.91, 10.9], ANC visit during last pregnancy (AOR [95% CI] = 4.26 [1.1, 16.4], maternal education level (AOR [95%CI] =11.98 [3.36, 41.4] and knowledge of mothers on pregnancy and delivery services (AOR [95% CI] = 2.97[1.1, 8.6] had significant associations with institutional delivery service utilization. Conclusions Very low institutional delivery service utilization was observed in the study area. Majority of the births at home were assisted by family members and relatives. ANC visit and lack of

    BackgroundThe mosquito Aedes aegypti is the main vector of dengue, Zika, chikungunya and yellow fever viruses. This major disease vector is thought to have arisen when the African subspecies Ae. aegypti formosus evolved from being zoophilic and living in forest habitats into a form that specialises on humans and resides near human population centres. The resulting domestic subspecies, Ae. aegypti aegypti, is found throughout the tropics and largely blood-feeds on humans.ResultsTo understand this transition, we have sequenced the exomes of mosquitoes collected from five populations from around the world. We found that Ae. aegypti specimens from an urban population in Senegal in West Africa were more closely related to populations in Mexico and Sri Lanka than they were to a nearby forest population. We estimate that the populations in Senegal and Mexico split just a few hundred years ago, and we found no evidence of Ae. aegypti aegypti mosquitoes migrating back to Africa from elsewhere in the tropics. The out-of-Africa migration was accompanied by a dramatic reduction in effective population size, resulting in a loss of genetic diversity and rare genetic variants.ConclusionsWe conclude that a domestic population of Ae. aegypti in Senegal and domestic populations on other continents are more closely related to each other than to other African populations. This suggests that an ancestral population of Ae. aegypti evolved to become a human specialist in Africa, giving rise to the subspecies Ae. aegypti aegypti. The descendants of this population are still found in West Africa today, and the rest of the world was colonised when mosquitoes from this population migrated out of Africa. This is the first report of an African population of Ae. aegypti aegypti mosquitoes that is closely related to Asian and American populations. As the two subspecies differ in their ability to vector disease, their existence side by side in West Africa may have important implications for

    Full Text Available Although numerous studies on heroin-assisted treatment (HAT have been published in leading international journals, little attention has been given to HAT's clients, their stories, and what constitutes the most influential factor in the treatment process. The present study investigates the role of HAT in transforming the lives of injection drug users (IDUs in Vancouver, Canada. This study is qualitative focusing on 16 in-depth interviews with patients from the randomized trials of HAT. Interviews were transcribed verbatim and analyzed thematically using NVivo 10 software. The findings revealed a positive change in many respects: the randomized trials reduce criminal activity, sex work, and illicit drug use. In addition, the trials improved the health and social functioning of its clients, with some participants acquiring work or volunteer positions. Many of the participants have been able to reconnect with their family members, which was not possible before the program. Furthermore, the relationship between the staff and patients at the project appears to have transformed the behavior of participants. Attending HAT in Vancouver has been particularly effective in creating a unique microenvironment where IDUs who have attended HAT have been able to form a collective identity advocating for their rights. The result of this research points to the need for continuation of the project beyond the current study, leading toward a permanent program.

    Full Text Available Although the flora of Africa is rather poor in plant species when compared to the floras of Tropical America or South-east Asia, this vast continent is the home of a wide range of plants useful to Man. Many of these have become famous in cultivation around the world. Coffee now provides an important source of income for certain countries, and the Yams yield one of the world’s staple foods. The Oil Palm and Cola trees are widely cultivated in Africa itself and elsewhere. African Mahoganies and Ironwoods are much sought after timber trees of excellent quality. Numerous grasses and pulses are well-known for their food value, and some of the native Cucurbitaceae are appreciated additions to our vegetable diet. African plants have also made their contribution to horticulture, ranging from world-famous trees such as the African or Gabon Tulip tree and many of the South African species of Proteaceae to the multitude of East and South African succulents. The present paper provides a survey of the most important of these useful plants and will emphasize the need of further research for forestry and agricultural as well as horticultural purposes, especially as far as some still little-known but potentially important plants species are concerned.

    Full Text Available Forty cases of Austin Moore Replacement done for transcervical fractures of the femur in patients were reviewed after a period of 12 to 48 months postoperatively (mean 26 mth. 30 cases (75% had mild to severe pain of non-infective origin, starting as early as 6 months postoperatively. This was irrespective of the make, size or position (varus/valgus of the prosthesis. Though the Aufranc and Sweet clinical scoring was satisfactory in 65% cases, radiological evidence of complications like sinking, protrusion, etc. were seen in majority of the cases. Calcar resorption was seen in 34 cases (85% as early as 4 months postoperatively. Results of THR and bipolar replacement done for transcervical fractures in recent literature show 85% pain-free cases at 5 years. We feel that Austin Moore Replacement should be reserved for patients more than 65 years of age and those who are less active or debilitated because of other factors, because of increased acetabular wear with time in the younger individual. This is corroborated by unsatisfactory results in patients less than 65 years of age (p < 0.05.

    2010-01-01

    We present here the complete paleomagnetic laboratory results from a collection of approximately 1500 oriented cores from all 16 of the Galapagos Islands, Ecuador, collected by Allan Cox in 1964–1965 but nearly all previously unpublished. The islands are located in the eastern Pacific Ocean within 1.4° of latitude from the equator and range in age from historically erupted to 3 Ma, mostly determined by published K-Ar and 3He isotopic dating. The number of sites collected on each island ranges from 1 to 28, for a total of 186. After combining duplicate site mean directions, 149 are used for an overall mean direction and 8 represent excursions and one reversal path. Divided by geomagnetic polarity chron, 110 site means are Brunhes or Jaramillo (normal polarity), 27 are Matuyama (reversed polarity), and 12 are Gauss (both polarities). We have completed the magnetic cleaning that was commenced in the late 1960s. Secondary (mostly viscous) magnetizations were nearly all removed by alternating field demagnetization at 10 mT. We have used the so-called blanket cleaning method, generally at 10 mT. All sites were in basalt flows and gave good paleomagnetic results; none was rejected in toto, and only a few core specimens were magnetically unsatisfactory. Nearly all sites had eight independently oriented cores, and within-site angular standard deviations of directions range from 1° to 8°. We used both Fisher and Bingham statistics to analyze the data and found that many of the direction populations are strongly elongate along the paleomagnetic meridian, while the corresponding virtual pole (VGP) populations are essentially circularly distributed. The paleomagnetic poles, calculated as the means of VGPs, are as follows: Brunhes and Jaramillo, north latitude = 86.9°, east longitude = 245.1°, and 95% confidence radius A95 = 1.9°; Matuyama, latitude = 87.2°, longitude = 158.2°, and A95 = 3.8°; Gauss, latitude = 83.0°, longitude = 204.7°, and A95 = 7.0°.

    The objective of this study was to evaluate the patterns of use of complementary alternative medicine (CAM) in a representative adult population in Germany. A population-based telephone survey was conducted in Lübeck, Germany. We performed computer-assisted telephone interviews (CATI) in order to obtain information on demographics, health status, prevalence of CAM usage, motivation for using CAM, type of CAM and health problems for which CAM were used. 1,001 adults (median age 48 years) participated in the study (response 46.8%). 79.6% of the interviewed subjects reported health problems. The most frequently named problems were chronic pain (45.3%), circulation problems (32.9%) and colds with fever (27.8%). Non-users of CAM had a lower incidence (76.6%) of overall illness than users (83.5%) (OR 0.65, 0.47-0.89). 42.3% of the participants had used CAM. The CAM user group consisted of significantly more females (72.8 vs. 55.5%) (OR 2.32, 1.74-3.08) and involved better educated subjects (school education >12 years, 36.6 vs. 27.9%, OR 3.25, 1.35-7.81) than the non-user group. The main health problems for which CAM was used were chronic pain (36.3%), some cases of uncomplicated colds (16.9%) and for improving general health (14.7%). Three procedures accounted for the majority of usage: Acupuncture (34.5%), homeopathy (27.3%) and herbal medicine (9.7%). A large number of participants reported as the main reason for using CAM the wish to avoid drugs as much as possible (31.7%). 26.7% reported opting for CAM due to the recommendation of their physician. 23.9% gave unsatisfactory results of conventional medicine as reason for CAM usage. CAM is used widely for different complaints by the general population. This frequent use of CAM has implications for the health-care system and health policy.

    Full Text Available Purpose: Myelomeningocele is one of the most common birth defects. It is associated with severe neurological deficiencies, and ocular changes, such as strabismus, are very common. The purpose of this study was to describe indications for strabismus surgery in patients with myelomeningocele and to evaluate the results achieved with surgical correction. Methods: We retrospectively reviewed records of all patients with myelomeningocele who underwent surgery for strabismus correction in a 5-year period in an institution for disabled children. Results: The main indications for strabismus surgery were esotropia and A-pattern anisotropia. Excellent surgical results were achieved in 60.9% of patients, satisfactory in 12.2%, and unsatisfactory in 26.9%. Conclusion: Patients with myelomeningocele and strabismus had a high incidence of esotropia and A-pattern anisotropia. Strabismus surgery in these patients had an elevated percentage of excellent and satisfactory results, not only for the ocular deviation, but also for improvement of head posture.

    Full Text Available The biblical text accords a great deal of attention to King Solomon’s personal abilities and governmental power. Solomon was described as a judge, poet, constructor and the wisest of all people in the Ancient Near East and Egypt. The current study discusses the interpretation of the midrashim that show how Solomon’s wisdom was manifested in his considerable knowledge of ornithomancy, that is, divination using birds, a practice that was considered as an important wisdom in the ancient world because of its practical applications, particularly in the military sphere. It seems that Solomon’s portrayal as a magician is intended and aimed at emphasising his abilities and his impressive character. Moreover, it may have had the purpose of disproving the conception of Solomon as inferior to his surroundings in this respect and the idea that he or his kingdom could be controlled by nations that command this type of wisdom.

    Viviparity (giving birth to live young) in fossil reptiles has been known only in a few marine groups: ichthyosaurs, pachypleurosaurs, and mosasaurs. Here, we report a pregnant specimen of the Early Cretaceous Hyphalosaurus baitaigouensis, a species of Choristodera, a diapsid group known from unequivocal fossil remains from the Middle Jurassic to the early Miocene (about 165 to 20 million years ago). This specimen provides the first evidence of viviparity in choristoderan reptiles and is also the sole record of viviparity in fossil reptiles which lived in freshwater ecosystems. This exquisitely preserved specimen contains up to 18 embryos arranged in pairs. Size comparison with small free-living individuals and the straight posture of the posterior-most pair suggest that those embryos were at term and had probably reached parturition. The posterior-most embryo on the left side has the head positioned toward the rear, contrary to normal position, suggesting a complication that may have contributed to the mother’s death. Viviparity would certainly have freed species of Hyphalosaurus from the need to return to land to deposit eggs; taking this advantage, they would have avoided intense competition with contemporaneous terrestrial carnivores such as dinosaurs.

    Full Text Available Numerous procedures have been developed to provide adequate enteral nutrition to patients with gastrointestinal disorders. Previously, operative placement of a feeding gastrostomy or jejunostomy tube was the accepted means of gaining chronic enteral access. However, improved technology and experience with endoscopic techniques have quickly replaced primary operative placement of enteral access. Direct percutaneous endoscopic jejunostomy (D-PEJ is a procedure that was designed to deliver enteral feeding solutions for patients with proximal disease after unsatisfactory results from percutaneous endoscopic gastrostomy tubes with jejunal extensions (PEG-J. As with any procedure, it is associated with complications. We present the first reported case of a colojejunal fistula resulting from a D-PEJ placement. While D-PEJ has been shown to be relatively safe, complications related to the inherent limitations of the procedure need to be considered when the patient experiences unusual post-procedure symptoms and worked up appropriately.

    Full Text Available Background: Valgus foot is a common foot deformity in spina bifida. The most popular operation for the valgus deformity has been the Grice talocalcaneal blocking. It has not been studied primarily in children with spina bifida. We report a prospective series, we present the results of hind foot valgus deformity of children with spina bifida, using Grice talocalcaneal arthrodesis with a tricortical iliac bone graft. Materials and Methods: Between May 2000 and December 2003, 21 patients with bilateral (42 feet valgus deformity of feet underwent surgery. There were 7 males and 14 females. The mean age of patients was 67.7 months (range 50-108 months. Results: The total number of feet that had nonunion was 11, in 7 of them the grafts were completely reabsorbed and the outcome of all these feet was unsatisfactory. Four feet had partial union of which three had unsatisfactory and one had satisfactory outcome. Sixteen feet had residual valgus deformity at the last followup visit, 10 patients had nonunion, and 6 had inadequate correction. Mean preoperative talocalcaneal and calcaneal pitch angles were 48.5΀ and 31.9΀, respectively, which decreased to 38.5΀ and 29.1΀, respectively, postoperatively. The decrease in talocalcaneal angle and calcaneal pitch was significant between preoperative and postoperative measurements (P<0.05. Conclusion: Grice subtalar arthrodesis technique is still a valuable option for valgus foot in patients with spina bifida. In this study, we found more encouraging results in older patients.

    To evaluate the clinical effectiveness of fluoroscopically guided balloon dilation in the treatment of esophageal achalasia. Under fluoroscopic guidance, 21 balloon dilation procedures were performed in 14 patients with achalasia. A balloon with a diameter of 20 mm was used for the initial attempt.If the patient tolerated this well, the procedure was repeated with a 10-20 mm balloon, placed alongside at the same session. If, however the patient complained of severe chest pain and/or a postprocedural esophagogram showed an improvement,the additional balloon was not used. For patients whose results were unsatisfactory, the dilation procedure was repeated at sessions three to seven days apart. Succesful dilation was achieved in 13 of 14 patients(92.9%), who needed a total of 20 sessions of balloon dilation, ranging from one to three sessions per patient(mean, 1.54 sessions). Esophageal rupture occured in one of 14 patients(7.1%) ; of the 13 patients who underwent a successful dilation procedure, 12(92.3%) were free of recurrent symptoms during the follow-up period of 1-56(mean, 18.5) months. The remaning patient(7.7%) had a recurrence seven months after dilation. Fluoroscopically guided balloon dilation seems to be safe and effective in the treatment of esophageal achalasia.

    The Russian-American Gallium solar neutrino Experiment (SAGE) is described. The solar neutrino flux measured by 31 extractions through October, 1993 is presented. The result of 69+/-10(stat)+5/-7(syst) SNU is to be compared with a Standard Solar Model prediction of 132 SNU. The initial results of a measurement of experimental efficiencies are also discussed by exposing the gallium target to neutrinos from an artificial source. The capture rate of neutrinos from this source is very close to that which is expected. The result can be expressed as a ratio of the measured capture rate to the anticipated rate from the source activity. This ratio is 0.93+0.15, -0.17 where the systematic and statistical errors have been combined. To first order the experimental efficiencies are in agreement with those determined during solar neutrino measurements and in previous auxiliary measurements. One must conclude that the discrepancy between the measured solar neutrino flux and that predicted by the solar models can not arise from an experimental artifact. (author)

    An emitter made of a directionally solidified Mo-Al 2 O 3 , Cr 2 O 3 eutectic was provided by Eindhoven University of Technology in Eindhoven, The Netherlands. Although the high temperature braze cycle used in bonding this electrode to the emitter substrate destroyed its characteristic needle microstructure, the converter gave good performance. Apparently, chemical species evaporated from the emitter onto the collector provided a low collector work function. The resulting low barrier indices suggest that this surface is a promising emitter

    Full Text Available Although treatment of visceral leishmaniasis with pentavalent antimony is usually successful, some patients require second-line drug therapy, most commonly with amphotericin B. To identify the clinical characteristics that predict an inadequate response to pentavalent antimony, a case-control study was undertaken in Teresina, Piaui, Brazil. Over a two-year period, there were 19 cases of VL in which the staff physicians of a hospital prescribed second-line therapy with amphotericin B after determining that treatment with pentavalent antimony had failed. The control group consisted of 97 patients that were successfully treated with pentavalent antimony. A chart review using univariate and multivariate analysis was performed. The cure rate was 90% with amphotericin B. The odds ratio for the prescription of amphotericin B was 10.2 for children less than one year old, compared with individuals aged over 10 years. Patients who presented coinfection had an OR of 7.1 while those on antibiotics had an OR of 2.8. These data support either undertaking a longer course of therapy with pentavalent antimony for children or using amphotericin B as a first-line agent for children and individuals with coinfections. It also suggests that chemoprophylaxis directed toward bacterial coinfection in small children with VL may be indicated.

    Full Text Available Une expérimentation a été conduite en 1996 au niveau de l'aménagement hydroélectrique de St. Cricq (gave d'Ossau dans le but de tester deux dispositifs de dévalaison destinés à éviter le passage dans les turbines des smolts de saumon atlantique (Salmo sala L.. Le premier, localisé au barrage, consiste en une barrière acoustique répulsive destinée à détourner les smolts vers un clapet de décharge. Le champ sonore, généré par 16 émetteurs immergés, est dans la gamme de fréquence 100-600 Hz avec un niveau sonore maximal de 120-130 dB. Le deuxième dispositif, localisé à l'usine, consiste en un exutoire de surface situé en rive, à proximité immédiate de la grille de prise d'eau. L'efficacité des deux dispositifs a été évaluée par marquage-recapture et le comportement des smolts a été suivi par radiotélémétrie. Les passages de smolts par le clapet du barrage varient de 20 % à 60 % ; cette efficacité résulte essentiellement du débit élevé transitant par le clapet. Les tests effectués avec et sans barrière acoustique n'ont mis en évidence aucun effet significatif du champ sonore. L'efficacité de l'exutoire du bassin de mise en charge est d'environ 80 %. La faible largeur de la prise d'eau (11 m, le faible espacement des barreaux de la grille de prise d'eau (2,5 cm, les conditions hydrauliques devant la grille qui guident rapidement les poissons vers l'entrée de l'exutoire, et la configuration de l'entrée de l'exutoire qui crée un écoulement à faible gradient de vitesse peuvent expliquer l'efficacité élevée de ce dispositif.

    2014-12-01

    Full Text Available Background: the occurrence of psychogenic non-epileptic seizures (PNES is estimated to be between 2 to 33 cases in every 100,000 inhabitants. The number of patients with PNES reaches 19% of those treated as epileptics. Patients with PNES are treated as if they had intractable epilepsy, with unsatisfactory results even after medication treatment is used to its maximum. The aim of this study is to present the effects of individual psychoanalytical treatment in patients with PNES, assessing its impact in the evolution of the clinical picture and its association with sex, time of disease, social, psychological and professional harm, as well as going through with treatment. Methods: The case base was composed of 37 patients with PNES. The diagnosis was reached with video-EEG monitoring. Psychoanalytical treatment was carried out through 12 months of weekly sessions timed for around 50-minutes each, in a total of 48 individual sessions. Results: This study found a high rate of success in the treatment of PNES patients. 29.7% (n=11 of patients had cessation or cure of symptoms and 51.4% (n=19 had a decrease in the number of episodes. There is an association between cessation or decrease in the number of episodes and sex (p<0.01, religion (p<0.01 and concluding treatment (p<0.01. Conclusion: Individual psychoanalytical treatment applied to patients with PNES is considered effective and can be an essential form of assistance for the reduction or cessation of episodes.

    To analyze cases of false diagnoses from a large series to help increase the accuracy of fine needle aspiration of palpable breast lesions. The results of FNA of 835 palpable breast lesions were analyzed to determine the reasons for false positive, false negative and false suspicious diagnoses. Of the 835 aspirates, 174 were reported as positive, 549 as negative and 66 as suspicious or atypical but not diagnostic of malignancy. Forty-six cases were considered unsatisfactory. Tissue was available for comparison in 286 cases. The cytologic diagnoses in these cases were reported as follows: positive, 125 (43.7%); suspicious, 33 (11.5%); atypical, 18 (6.2%); negative, 92 (32%); and unsatisfactory, 18 (6.2%). There was one false positive diagnosis, yielding a false positive rate of 0.8%. This lesion was a case of fibrocystic change with hyperplasia, focal fat necrosis and reparative atypia. There were 14 false negative cases, resulting in a false negative rate of 13.2%. Nearly all these cases were sampling errors and included infiltrating ductal carcinomas (9), ductal carcinomas in situ (2), infiltrating lobular carcinomas (2) and tubular carcinoma (1). Most of the suspicious and atypical lesions proved to be carcinomas (35/50). The remainder were fibroadenomas (6), fibrocystic change (4), gynecomastia (2), adenosis (2) and granulomatous mastitis (1). A positive diagnosis of malignancy by FNA is reliable in establishing the diagnosis and planning the treatment of breast cancer. The false-positive rate is very low, with only a single case reported in 835 aspirates. Most false negatives are due to sampling and not to interpretive difficulties. The category "suspicious but not diagnostic of malignancy" serves a useful purpose in management of patients with breast lumps.

  7. The Use of Data Mining Methods to Predict the Result of Infertility Treatment Using the IVF ET Method

    Directory of Open Access Journals (Sweden)

    Malinowski Paweł

    2014-12-01

    Full Text Available The IVF ET method is a scientifically recognized infertility treat- ment method. The problem, however, is this method’s unsatisfactory efficiency. This calls for a more thorough analysis of the information available in the treat- ment process, in order to detect the factors that have an effect on the results, as well as to effectively predict result of treatment. Classical statistical methods have proven to be inadequate in this issue. Only the use of modern methods of data mining gives hope for a more effective analysis of the collected data. This work provides an overview of the new methods used for the analysis of data on infertility treatment, and formulates a proposal for further directions for research into increasing the efficiency of the predicted result of the treatment process.

    Full Text Available Purpose. To summarize the experience in treating patients with genitoplasty due to disorders of sex development in China. Methods. The operative procedures, gender of rearing, surgical outcome, and psychosocial and family adjustments of 262 patients were reviewed retrospectively. Results. At initial diagnosis, the mean age was years (range: 2–38 years. There were 96 children, 133 adolescents, and 33 adults. Follow-up was done every 6 months. Patients with female sex assignment had no urinary incontinence or voiding difficulty. Five patients underwent the second surgery (3%; vaginal dilation was performed in 35 patients with postoperative vaginal stenosis; 12 patients (7.4% were unsatisfactory with the outcome. For patients with male sex assignment, the median length of penis was 2.2 cm in prepubertal patients, 4.2 cm in pubertal patients, and 5.0 cm in adults; 39 patients developed postvoid dribbling (39%; 21 patients underwent a second surgery (21%; urethral dilation was done in 28 patients (28% due to urethral stricture; 38 patients were unsatisfactory with the outcome (38%. In addition, 136 patients (83% with female sex assignment and 54 (54% with male sex assignment had favorable psychosocial adjustment. Conclusions. Patients with male sex assignment have more surgical complications and difficulties in psychosocial adjustment as compared to those with female sex assignment.

    During the past few years high rates of recidivation have increasingly been reported following drug treatment for hyperthyroidism. In view of these unsatisfactory results it is only natural that the use of surgery and ratioiodine treatment is now more often considered in order to achieve complete elimination of the metabolic disorders caused by hyperactivity of the thyroid gland. The aim of this study was to investigate into the effectiveness of radioiodine therapy in a large cohort of patients (n = 925). Particular attention was given to the influence of the dose applied to the thyroid tissue on the rates of success achieved in immunogenic hyperthyroidism (IH) and autonomous disorders (non-immunogenic hyperthyroidism = NIH).

    2016-02-01

    Based on the results of 19 food microbiology proficiency testing (PT) schemes, this study aimed to assess the laboratory performances, to highlight the main sources of unsatisfactory analytical results and to suggest areas of improvement. The 2009-2015 results of REQUASUD and IPH PT, involving a total of 48 laboratories, were analysed. On average, the laboratories failed to detect or enumerate foodborne pathogens in 3·0% of the tests. Thanks to a close collaboration with the PT participants, the causes of outliers could be identified in 74% of the cases. The main causes of erroneous PT results were either pre-analytical (handling of the samples, timing of analysis), analytical (unsuitable methods, confusion of samples, errors in colony counting or confirmation) or postanalytical mistakes (calculation and encoding of results). PT schemes are a privileged observation post to highlight analytical problems, which would otherwise remain unnoticed. In this perspective, this comprehensive study of PT results provides insight into the sources of systematic errors encountered during the analyses. This study draws the attention of the laboratories to the main causes of analytical errors and suggests practical solutions to avoid them, in an educational purpose. The observations support the hypothesis that regular participation to PT, when followed by feed-back and appropriate corrective actions, can play a key role in quality improvement and provide more confidence in the laboratory testing results. © 2015 The Society for Applied Microbiology.

    Full Text Available Aim. Improvement of complex treatment results in patients with diabetic foot syndrome by introducing methods of gravitational surgery and α-lipoic acid. Methods. The results of treatment were analyzed for 558 patients with diabetic foot syndrome treated in Scientific Centre of Surgery named after M.A. Topchubashov (Baku, Azerbaijan from 1988 to 2015. The age varied from 28 to 83 years. The patients included 416 men and 142 women. The control group included 90 patients who at the perioperative period underwent basic therapy including antibiotics, anticoagulants, antiaggregants, dextrans, angioprotectors, spasmolytics, corticosteroids, narcotic and non-narcotic analgesics. The study group included 468 patients, along with traditional therapy receiving efferent methods (plasmapheresis, ultraviolet blood irradiation, ozone therapy and α-lipoic acid. 282 patients of the study group received outpatient treatment and 186 - complex inpatient surgical treatment. A comparative evaluation of the results was performed separately in three groups: angiopathy, neuropathy, angioneuropathy. The results were evaluated by clinical and instrumental examinations before and after treatment (6, 12, 60 months and more. Results. In the study group a satisfactory result of treatment was registered in 85.5% of patients, in the control group - in 62.2%, unsatisfactory in 14.5 and 37.8% of patients, respectively (p=0.046. Conclusion. The use of efferent methods and α-lipoic acid provided prompt elimination of numerous pathogenetic disorders observed in diabetes mellitus, decrease of amputation frequency and improvement of complex surgical treatment results in patients with diabetic foot syndrome.

    Quality of life is a subjectively interpreted phenomenon that can be profoundly altered by the presence of a wound. Particularly when complete and expedient healing seems unrealistic, quality of life becomes the focus of care. To assess the influence of a variety of chronic wounds on patient quality of life, a 1-day, descriptive study was conducted among 50 consecutive outpatients (64% men, 36% women; age range 14 to 78 years) with chronic wounds who attended the Wound Clinic of the University Hospital, Varanasi, India. A quality-of-life questionnaire containing six parameters (physical activities, feelings, household duties, leisure time activities, social relations, and general activities) was developed and administered. Demographic information was available as a result of a previous study at this institution. Quality-of-life scores were grouped as satisfactory and unsatisfactory and participants were grouped by age (60 years old). Wounds were classified by cause (diabetes, venous disease, pressure ulcer, and tuberculosis) and size (50 cm2). The most common site was the lower limb or foot (39, 78%), followed by upper limb (six, 12%) and head, neck, and trunk (five, 10%). More than half (28, 56%) of all patients had an unsatisfactory overall quality-of-life score. The percentage of patients with satisfactory scores was higher in patients with smaller versus larger wounds and wounds located on upper rather than lower limbs, as well as in middle-aged versus younger or older patients. This patient-centered instrument helped document important quality-of-life concerns among chronic wound patients.

    The 30 Doradus nebula in the Large Magellanic Cloud (LMC) contains the massive starburst cluster NGC 2070 with a massive and probably younger stellar sub clump at its centre: R136. It is not clear how such a massive inner cluster could form several million years after the older stars in NGC 2070, given that stellar feedback is usually thought to expel gas and inhibit further star formation. Using the recently developed 1D feedback scheme WARPFIELD to scan a large range of cloud and cluster properties, we show that an age offset of several million years between the stellar populations is in fact to be expected given the interplay between feedback and gravity in a giant molecular cloud with a density ≳500 cm-3 due to re-accretion of gas on to the older stellar population. Neither capture of field stars nor gas retention inside the cluster have to be invoked in order to explain the observed age offset in NGC 2070 as well as the structure of the interstellar medium around it.

  5. The understandings and meanings eight seventh and eighth grade Latinas gave to science

    Parker, Carolyn Ann

    My study examined the experiences of eight seventh and eighth grade girls of Central American descent, in and out of the science classroom. The study was interpretive in design and explored the question, "How did the eight participants understand and make meaning of science?" Guided by a sociocultural perspective and a socially critical stance, I explored issues of educational access, particularly to science, mediated by the relationships and experiences formed by families, peers, science classrooms, schools, and society. Data sources included monthly individual interviews, regular focus group meetings, school observations, and interviews with teachers and family members. Findings include the importance of school science experiences that emphasize hands-on activities and the study of topics relevant to students' everyday lives. School influences that I discuss include English-as-a-Second Language learning, English language ability and its effect on classroom interactions, ability grouping, standardized testing, and teachers' instructional practices. Out-of-school influences I examine include the national science education reform movement, familial expectations, and society and the media's portrayal of science and the scientist. The implications and recommendations of the study are particularly germane to practice. Recommendations for the science classroom include a continued emphasis on hands-on science experiences that incorporate high academic expectations for all students, including second-language learners. Moreover, curriculum should be connected and relevant to students' everyday experiences. Recommendations for outside-the-science classroom include a thoughtful examination of the educational environment created by a school's tracking policy and continued support of meaningful professional development experiences for teachers. Future research and the subsequent development of theory should include a further analysis of the influence of gender, ethnicity, science, and recently immigrated students. A study of the influence of English-language ability on students' educational experiences would be especially informative. Studies like this can assist the science education community to implement gender and culturally-equitable curricula, instructional materials, and assessment strategies that could better meet the needs of students who have historically been underrepresented in the discipline, including, but not limited to, second-language learners and recent immigrants to the United States.

    A modification of the method of Thakur et al. for labelling polynuclear cells with 8-hydroxyquinolein-indium-complexe utilising the water soluble sulfate of the substance was applied. The labelling procedure gave a yield over 98% with erthrocytes and over 80% with platelets and polynuclear cells using at least 1 x 10 8 plasma free cells. Functional capacity of the labelled cells remained unaltered. Injection double labelled ( 111 In, 51 Cr) red cells correlation of values for the red cell volume amounted to r = 0,98 (n=20); red cell life-spane measurements gave comparable results in 5 patients. After injecting labelled platelets a life-spane between 6,5 and 11 days was measured. Scintigraphic visualisation of pulmonary embolism was obtained 30 minutes after injecting labelled platelets. Injection of labelled polynuclear cells allows life-spane measurements as well as detection of abscesses. (author)

    Tricuspid valve insufficiency (TI) following cardiovascular surgery causes right-side heart failure and hepatic failure, which affect patient prognosis. Moreover, the benefits of reoperation for severe tricuspid insufficiency remain unclear. We investigated the surgical outcomes of reoperation in TI. From the Japan Cardiovascular Surgery Database (JACVSD), we extracted cases who underwent surgery for TI following cardiac surgery between January 2006 and December 2011. We analysed the surgical outcomes, specifically comparing tricuspid valve replacement (TVR) and tricuspid valve plasty (TVP). Of the 167 722 surgical JACVSD registered cases, reoperative TI surgery occurred in 1771 cases, with 193 TVR cases and 1578 TVP cases. The age and sex distribution was 684 males and 1087 females, with an average age of 66.5 ± 10.8 years. The overall hospital mortality was 6.8% and was significantly higher in the TVR group than in the TVP group (14.5 vs 5.8%, respectively; P tricuspid surgery were unsatisfactory. Although TVR is a last resort for non-repairable tricuspid lesions, it carries a significant risk of surgical mortality. Improving the patient's preoperative status and opting for TVP over TVR is necessary to improve the results of reoperative tricuspid surgery. © The Author 2014.

    Regular service audits since 2008 gave a stoma care department confidence in the service it provides. In 2016 the department undertook a new audit to benchmark its services, using the Association of Stoma Care Nurses (ASCN) UK Revised Stoma Care Nursing Standards and Audit Tool (2015) . Of the 60 questionnaires given out, 43 were returned (71%). The results highlighted areas of good practice with positive patient feedback. However, it also identified that the team needed to improve documentation when offering patients the opportunity to meet a former patient with a stoma preoperatively and when discussing lifestyle issues. The results demonstrated poor preoperative compliance; this was lower than expected and did not concur with department statistics. The audit highlights the importance of clarity when developing a questionnaire to ensure all respondents not only interpret its meaning in the same way, but also only answer the questions specific to them.

Le dispositif de dévalaison est situé en rive droite à proximité immédiate du plan des grilles. Le débit moyen alimentant l'exutoire a varié au cours de l'étude de 0,4 m3/s à 1,2 m3/s ce qui correspond à 1,6 % à 4,3 % du débit turbiné. Lefficacité du dispositif a été évaluée grâce à la technique de marquage-recapture. Le comportement des smolts dans le canal d'amenée a été suivi par radiotélémétrie. L'efficacité de l'exutoire (moyenne : 17 % s'est révélée très faible en 1995 â cause de conditions hydrauliques défavorables. Un mur déflecteur a été mis en place en 1997 afin de modifier l'écoulement dans le canal et améliorer le guidage des poissons vers l'entrée du dispositif de dévalaison. L'efficacité de l'exutoire est passée à 55 %. Le comportement des poissons à l'amont immédiat des grilles de prise d'eau est très dépendant des conditions hydrodynamiques dans le canal d'amenée. L'efficacité de l'exutoire semble croître avec la longueur des poissons, la proportion des classes de taille inférieures à 19 cm étant plus faible sur les poissons piégés que sur les poissons lâchés. Cette sélection est très certainement liée à l'espacement relativement important des barreaux des grilles de la prise d'eau (30 mm qui malgré le courant tangentiel au plan de grilles demeurent plus perméables aux individus les plus petits. L'éclairage de l'entrée de l'exutoire ne paraît pas avoir d'influence sur les déplacements des poissons radiomarqués dans le canal d'amenée, le facteur hydraulique étant prépondérant. Il modifie cependant les rythmes de passage des poissons par l'exutoire.

    Assisted reproduction is traditionally regarded as effective when it results in a high pregnancy rate per started treatment cycle. For the patients, it is more interesting to know how high the probability is of giving birth during a full course of assisted reproduction treatment. Retrospective series of 546 patients followed for three years of assisted reproduction at a public fertility clinic. During the follow-up period, 347 of the patients (63.6%) gave birth by means of assisted reproduction. Of the 199 remaining patients, 70 (12.8% of 546) stopped treatment because they had completed the three treatment cycles that are covered by public funding. Thirty seven patients (6.8% of 546) conceived without assisted reproduction. Assisted reproduction at public fertility clinics in Norway is as effective as that in our neighbouring countries. Over the past 18 years, the effectiveness of assisted reproduction has increased by about 50%.

    1976-01-01

    Investigations on the interspecific hybridization in sunflower, aimed at developing a diversified initial selection material, were carried out Wild species of the diploid, tetraploid and hexaploid groups, varieties, hybrids, and selfed-lines of cultivated sunflower were used for crossings. To overcome incrossability between the species and sterility in the hybrids the method of f;cilitating of crossability by mutual gra'fting and gamma-rays treatment of seeds and pollen were applied. Results showed that: 1. By the method of interspecific hybridization forms might be produced resistant to more important diseases. 2. Interspecific hybridization in combination with other methods of selection might produce varieties and hybrids with a complex of valuable qualities. 3. Crossings between wild species and cultivated sunflower gave progenies with gene rale sterility. 4. The species H.tuberosus, H.scaberimus, H.arωphylus and H.lenticularis possess genes of full fertility restoration. (author)

    Oil prospecting in N. Bosnia was undertaken from 1898 till 1899, 1929 till 1941 and 1948 till 1963. Besides geological and geophysical prospecting, prospecting drillings have also been performed. Basic data of the results, especially of those in the post-war period, are given. Crude oil in the Tuzla Basin has been found in the Eocene and the middle Miocene-strata of the marine origin, as well as in freshwater Oligomiocene. The accumulation of oil in Pozarnica near Tuzla has the character of unsufficiently drained fissure bed. Test production gave 800 tons of oil before the last war. In Bosanska, Posavina and Semberija, the prospecting wells are located on the highest parts of pre-Neogene relief. (18 refs.)

  17. Unfavorable results in replantation

    Abraham G Thomas

    2013-01-01

    Full Text Available Reattachment of amputated parts of the body (Replantation has become a reality since the first arm replant was carried out six decades ago. Failures were not uncommon in the beginning, leading on to the analysis of the problem and refinements in technique. Improvements in sutures, instrumentation and better microscopes further helped the surgeons to do replantation with better finesse and functional results. Evaluation of results and particularly failure and long term results help the younger surgeons to learn from the difficulties faced earlier to do better in the future. An attempt is made to list various aspects of replantation experienced by the author during the past 30 years, particularly in reference to unfavorable results, which had been occasionally total failure, or a partial failure, with poor function and cosmesis due to infection. An insensate limb with poor function is the result of inadequate or improper nerve coaptation or infection destroying the whole repair. It is apt to mention that infection is mostly the result of poor vascularity due to devitalized tissue. Difficulties arise often in identifying the viable tissue, particularly while debriding in the distal amputated part since there is no bleeding. Experience counts in this, specifically to identify the viable muscle. The factors that may lead to complications are listed with remarks to avoid them.

    1983-01-01

    Between May, 1973 and December, 1980, 78 Stage I and II breast carcinomas in 76 patients were treated by biopsy and radiotherapy with curative intent. With a maximum follow-up of 10 years, a minimum of 2 1/2 years and a median follow-up of 3 1/2 years, a loco-regional control rate of 97% was obtained. Cosmetic results and treatment complications were studied. Patient characteristics, tumor size, excisional biopsy technique, axillary staging procedure and radiotherapy techniques were analyzed and all found to be important factors affecting cosmesis and complications. The most common complications included transient breast edema observed in 51% of patients, breast fibrosis (usually mild) seen in 23% of the population, axillary hematoma or seroma formation in 15%, mild arm edema in 14% and basilic vein thrombosis in 10% of patients. The causes of these and other less frequent complications are discussed. The overall cosmetic result was excellent in 78%, satisfactory in 18% and unsatisfactory in 4% of patients. Recommendations for improving cosmetic results and minimizing complications are made

    The following information can be derived from results so far for a final store: - With known mineralogy, precise information can be given on the solution metamorphosis processes to be expected. The previous results of this in-situ experiment have confirmed the theoretical considerations. - Sensors were developed and tested, which make possible continuous monitoring under hydrostatic pressure in a final store in the case of incoming solution, i.e. for exploration bores. - The collection of physical and chemical parameters in open sections and shafts creates the basis for assessing the effect of backfilling from the chemical point of view.

    The Russian-American Gallium solar neutrino Experiment (SAGE) began the second phase of operation (SAGE II) in September of 1992. Monthly measurements of the integral flux of solar neutrinos have been made with 55 tonnes of gallium. The K-peak results of the first nine runs of SAGE II give a capture rate of 66 -13 +18 (stat) -7 +5 (sys) SNU. Combined with the SAGE I result of 73 -16 +18 (stat) -7 5 (sys) SNU, the capture rate is 69 -11 +11 (stat) -7 +5 (sys) SNU. This represents only 52%--56% of the capture rate predicted by different Standard Solar Models

    Posterior calcaneal exostosis treatment modalities have given rise to many controversial opinions. After failure of the conservative treatment, surgical bursectomy and resection of the calcaneal exostosis are indicated by many authors. But clinical studies also show a high rate of unsatisfactory results with a relative high incidence of complications. The minimally invasive surgical technique by an endoscopic calcaneoplasty (ECP) could be an option to overcome some of these problems. Between 1999 und 2010 we operated 164 patients with an age range between 16 and 67 years, 81 males and 83 females. The radiological examination prior to surgery documented in all cases a posterior superior calcaneal exostosis that showed friction to the Achilles tendon. All patients included in the study had no clinical varus of the hind foot, nor cavus deformities. All patients had undergone a trial of conservative treatment for at least 6 months and did not show a positive response. The average follow-up was 46.3 (range: 8-120) months. According to the Ogilvie-Harris score 71 patients presented good and 84 patients excellent results, while 5 patients showed fair results, and 4 patients only poor results. All the post-operative radiographs showed sufficient resection of the calcaneal spur. In 61 patients the preoperative MRI showed a partial rupture of the Achilles tendon close to the insertion side. In no case could we observe a complete tear at the time of follow-up. Only minor postoperative complications were observed. In many patients we could observe a chondral layer at the posterior aspect of the calcaneus. Close to the intersion the Achilles tendon showed also in many patients a chondroide metaplasia. ECP is an effective and minimally invasive procedure for the treatment of patients with calcaneal exostosis. After a short learning curve the endoscopic exposure is superior to the open technique, has less morbidity, less operating time, and nearly no complications. Moreover, the

    The ultimate aim of the critical reading of medical literature is to use the scientific advances in clinical practice or for innovation. This requires an evaluation of the applicability of the results of the studies that have been published, which begins with a clear understanding of these results. When the studies do not provide sufficient guarantees of rigor in design and analysis, the conditions necessary for the applicability of the results are not met; however, the fact that the results are reliable is not enough to make it worth trying to use their conclusions. This article explains how carrying out studies in experimental or artificial conditions often moves them away from the real conditions in which they claim to apply their conclusions. To evaluate this applicability, the article proposes evaluating a set of items that will enable the reader to determine the likelihood that the benefits and risks reported in the studies will yield the least uncertainty in the clinical arena where they aim to be applied.

    1989-01-01

    Some recent developments in the experimental search for neutrino mass are discussed. Simpson and Hime report finding new evidence for a 17-keV neutrino in the β decay of 3 H and 35 S. New data from Los Alamos on the electron neutrino mass as measured in tritium beta decay give an upper limit of 13.5 eV at the 95% confidence level. This result is not consistent with the long-standing ITEP result of 26(5) eV within a ''model-independent'' range of 17 to 40 eV. It now appears that the electron neutrino is not sufficiently massive to close the universe by itself. 38 refs., 1 figs., 2 tabs

    The results indicate that the temperature fields in a rock mass containing geologic discontinuities can be predicted accurately using the simple theory of heat conduction. Geologic discontinuities appear to introduce significant nonlinear thermomechanical deformation into the rock mass, as a result of which the thermally induced displacements are much less than those predicted by the simple theory of thermo-elasticity. In addition, the assumption that the rock properties are temperature independent appears to increase the values predicted for these displacements significantly. Therefore, it is important that the temperature dependence of these properties is known and that these values be used in the calculations. The onset of significant thermal spalling along the walls of the heater boreholes appears to be related to conditions where the maximum induced compressive stress exceeds the uniaxial compressive strength of the rock. 7 figures

It also discusses the emerging scientific issues and challenges regarding the knowledge about biological and health effects of ionizing radiations, which requires investigations on the ecosystems, the effects of chronic low level exposures, and the propagation of effects at different biological levels (cells, tissue, individual, population, communities, and ecosystems). Then, it presents the IRSN environment-health research program, ENVIRHOM, its objectives, and its results concerning the environment on the one side, and health on the other side.

    Solar Thermal water heating has made little market penetration in some European countries. The main barriers to market development are: Long payback periods for the technology; Difficulties for the end-user in meeting the initial capital costs of the installation; Lack of confidence in the delivered energy that can be expected from the technology. The third barrier has been addressed using the concept of Guaranteed Solar Results (GSR). This project has addressed the other two main barriers using the concept of Solar Results Purchasing, (SRP) which combines GSR with Third Party Financing. The work was carried out in the UK, France, and Spain. The project used a uniform approach across the three countries. Each team calculated solar performance using an English version of the SOLO programme developed by TECSOL in France to encode the methodology for GSR model contracts. (author)

    Results from the nu_tau appearance search in a neutrino beam using the full NOMAD data sample are reported. A new analysis unifies all the hadronic tau decays, significantly improving the overall sensitivity of the experiment to oscillations. The "blind analysis" of all topologies yields no evidence for an oscillation signal. In the two-family oscillation scenario, this sets a 90% C.L. allowed region in the sin^2(2theta)-Delta m^2 plane which includes sin^2(2theta)nu_tau oscillation hypothesis results in sin^2(2theta)<1.5 x 10^{-2} at large Delta m^2 and Delta m^2 < 5.9 eV^2/c^4 at sin^2(2theta)=1.

    Selected results from LEP on electroweak neutral currents and strong interactions are reviewed. In the first part, total cross sections, angular and polarization symmetries are interpreted in terms of basic electroweak parameters, like the mass, total and partial widths of the Z and neutral current couplings. Special attention is given to two apparent problems: the discrepancy between the measurements with final state vs. initial state polarization; and the deviation of the measured width of the Z into heavy quarks from Standard Model expectations. These discrepancies are not very significant, but they are the only ones observed at this point and thus deserve attention. In the second part, I outline results on final state strong interactions, namely measurements pertaining to differences between quark and gluon jets and the QCD group structure.

    Last winter, in cooperation with agencies in 10 states and two metropolitan area counties, EPA measured the indoor air radon concentrations of 14,000 houses, some chosen statistically at random and some by request of the homeowner. Passive measurement methodologies were used, such as exposing a charcoal canister to the air for a few days and allowing the air to migrate in to the charcoal naturally. To reduce dilution of radon by the outside air, the protocol required that the house be shut up; therefore, the study was conducted during winter. The measuring device was placed in the lowest livable area (usually the basement) of each house to maximize potential concentration. It should be noted that these procedures are generally considered to be screening tests because they result in a worst-case measurement rather than a best value. The results of these findings are presented

    Amongst nondestructive examination methods, the ultrasonic examination plays an important role. The reason why its scope of application is so wide is because the sound conducting capacity is the only property the material of a test specimen has to have. As the fields are so manifold, only main aspects can be described briefly. The list of references, however, is very extensive and gives plenty of information of all the problems concerning the assessment of ultrasonic examination results. (orig./RW) [de

    1984-01-01

    An important decision has been made regarding the correction scheme for the arcs leading to the adoption of the so called scheme I. In this scheme the beam position data are collected from single-plane x and y Beam Position Monitors (BPMs), which are placed in the drift spaces adjacent to the downstream D- and F-magnets correspondingly. Similarly, single-plane x and y correctors are used for moving the upstream end of the corresponding magnets. In the present simulation this scheme is used exclusively. The first order calculations performed by means of TRANSPORT appear to be unsatisfactory from the point of view of the beam spotsize at the interaction point (IP). In this note we describe the modification to our program BEAMCORR which employs second order calculations by means of the program TURTLE. We also present the results of the following simulations: (a) study of the effects of two different levels of magnet misalignment on the beam spotsize at IP, and comparison of the results with those obtained by means of the program DINGBAT; (b) study of disjoints between achromats (both the displacement of the adjacent ends and angular discontinuity between achromats)

    A classification is made of wells according to the complexity of separation of the beds. Five categories are isolated. The criterion for comparing the categories was the presence or absence in the productive part of the section of water-bearing levels and screening beds. In a number of cases, as a result of unsatisfactory sedimentation stability of the cementing fluid, channels can be formed in it which may be the reason for transcolumn overflows and interruption in the removal of pure (not containing water) oil. In order to control transcolumn overflows in wells of the II-III-IV category, packer-filters (PFM) are used whose action is based on the forced recovery from the cement fluid of part of the liquid phase. The use of PFM is recommended only after conducting of a set of special (laboratory, geophysical, geological-technical, ect.) studies. The possibility is shown of positive use of PFM not only in the well shafts of nominal diameter, but also in wells prone to cavern formation. In the example of well No 13993 of the Abdrakhmanovskiy field, the possibility is shown of sectioning the PFM. Based on the PFM, and PFU was created with elongated filtering part. The results of introducing the PFU and the PFM are positive, and the economic effect from using the PFU is 1.5-fold greater than from PFM. In addition to PFU and PFM, the wells of the association ''Tatneft''' have used packers of the type PPG designed by the All-Union Scientific Research of Drilling Equipment. The results of introducing the packers PPG are positive.

    The U.S. Nuclear Regulatory Commission (NRC), Office of Nuclear Regulatory Research, is funding the Idaho National Engineering Laboratory (INEL) in performing research to provide technical input for their use in evaluating responses to Generic Letter 95-07, {open_quotes}Pressure Locking and Thermal Binding of Safety-Related Power-Operated Gate Valves.{close_quotes} Pressure locking and thermal binding are phenomena that make a closed gate valve difficult to open. This paper discusses only the pressure locking phenomenon in a flexible-wedge gate valve; the authors will publish the results of their thermal binding research at a later date. Pressure locking can occur when operating sequences or temperature changes cause the pressure of the fluid in the bonnet (and, in most valves, between the discs) to be higher than the pressure on the upstream and downstream sides of the disc assembly. This high fluid pressure presses the discs against both seats, making the disc assembly harder to unseat than anticipated by the typical design calculations, which generally consider friction at only one of the two disc/seat interfaces. The high pressure of the bonnet fluid also changes the pressure distribution around the disc in a way that can further contribute to the unseating load. If the combined loads associated with pressure locking are very high, the actuator might not have the capacity to open the valve. The results of the NRC/INEL research discussed in this paper show that the relationship between bonnet pressure and pressure locking stem loads appears linear. The results also show that for this valve, seat leakage affects the bonnet pressurization rate when the valve is subjected to thermally induced pressure locking conditions.

The results of the NRC/INEL research discussed in this paper show that the relationship between bonnet pressure and pressure locking stem loads appears linear. The results also show that for this valve, seat leakage affects the bonnet pressurization rate when the valve is subjected to thermally induced pressure locking conditions

    We will focus here on results from the 1999 data taking period, where 8 M Pb+Au events at 40 AGeV were recorded. Since the new readout system of the TPC was not yet properly working, this data set is limited in terms of statistics, and momentum resolution. Nevertheless, this data sample at lower beam energy allows to study initial conditions different from the ones at top SPS energy. This can be very useful to disentangle temperature and baryon density driven modifications of the dilepton spectrum. (15 refs).

    During the 1979 Megagauss II conference the hypervelocity potential of railguns and the pulsed power technology needed to power them were discussed. Since then, many laboratories have initiated railgun R and D projects for a variety of potential applications. Los Alamos and Lawrence Livermore National Laboratories initiated a collaborative experimental railgun project which resulted in several successes in accelerating projectiles to high velocities, emphasized the limits on railgun operation, and indicated that the numerical modeling of railgun operation was in good agreement with the experiments

    Recent (first or/and the best) results from the neutrino experiments are reviewed and their implications for the theory are discussed. The sense of the experiments is the searching for neutrino masses, mixing and interactions beyond the standard model. Present laboratory experiments give upper bounds on the masses and the mixing which are at the level of predictions of the ''electroweak see-saw''. Positive indications of nonzero lepton mixing follow from studies of the solar and atmospheric neutrinos. (author). 95 refs, 11 figs

    The Antarctic Muon and Neutrino Detector Array (AMANDA) is a high- energy neutrino telescope operating at the geographic South Pole. It is a lattice of photomultiplier tubes buried deep in the polar ice. The primary goal of this detector is to discover astrophysical sources of high energy neutrinos. We describe the detector methods of operation and present results from the AMANDA-B10 prototype. We demonstrate the improved sensitivity of the current AMANDA-II detector. We conclude with an outlook to the envisioned sensitivity of the future IceCube detector. (37 refs).

    The PAMELA satellite experiment was launched into low earth orbit on June 15th 2006. The combination of a permanent magnet silicon strip spectrometer and a silicon-tungsten imaging calorimeter allows precision studies of the charged cosmic radiation to be conducted over a wide energy range (100 MeV - several hundred GeV). A primary scientific goal is to search for dark matter particle annihilation by measuring the energy spectra of cosmic ray antiparticles. Latest results from the PAMELA experiment are presented with a particular focus on cosmic ray antiprotons and positrons.

    An overview is given of recent results obtained in tokamak devices. We introduce basic confinement scenarios as L-mode, H-mode and plasmas with an internal transport barrier and discuss methods for profile control. Important findings in DT-experiments at JET as α-particle heating are described. Methods for power exhaust like plasma regimes with a radiating mantle and radiative divertor scenarios are discussed. The overall impact of plasma edge conditions on the general plasma performance in tokamaks is illustrated by describing the impact of wall conditions on confinement and the edge operational diagram of H-mode plasmas

    Preliminary results form the CDF detector, based on analysis of data collected in Run 1a and Run 1b at the Tevatron, totaling 110 pb - 1 integrated luminosity, place new limits on the masses and couplings of new particles including charged Higgs bosons, supersymmetric gauge particles and quarks, and new vector bosons. One of the observed events, having an e + e - pair, two photons, and large missing energy would not occur with significant rate in the Standard Model, leading to speculation regarding its origin and the possible existence of related events

    Beginning with OSTA-1 in November 1981 and ending with Neurolab in March 1998, a total of 36 Shuttle missions carried various Spacelab components such as the Spacelab module, pallet, instrument pointing system, or mission peculiar experiment support structure. The experiments carried out during these flights included astrophysics, solar physics, plasma physics, atmospheric science, Earth observations, and a wide range of microgravity experiments in life sciences, biotechnology, materials science, and fluid physics which includes combustion and critical point phenomena. In all, some 764 experiments were conducted by investigators from the U.S., Europe, and Japan. The purpose of this Spacelab Science Results Study is to document the contributions made in each of the major research areas by giving a brief synopsis of the more significant experiments and an extensive list of the publications that were produced. We have also endeavored to show how these results impacted the existing body of knowledge, where they have spawned new fields, and if appropriate, where the knowledge they produced has been applied.

    Full Text Available The TOTEM experiment at the CERN LHC is focussed on the measurement of the elastic proton-proton scattering, the total pp cross-section, and all kinds of diffractive phenomena. Detectors housed in “Roman Pots” which can be moved close to the outgoing proton beams allow to trigger on elastic and diffractive protons and to determine their parameters like the momentum loss and the transverse momentum transfer. In addition, charged particle detectors in the forward regions detect almost all inelastic events. Together with the CMS detector, a large solid angle is covered enabling precise studies of Min. Bias as well as Single Diffractive and Double Pomeron Interactions. The results will considerably help the interpretation of the Cosmic Ray Showers at highest energies and will give insight into the proton structure and the QCD theory of strong interactions. TOTEM measured the elastic pp- scattering over a large range of t (the squared momentum transfer from 10-3 – 4 GeV2. Noneof the considered models could yield a satisfactory fit over the complete range. However, the exponential slope at low |t|-values and the position of the diffractiveminimum are well within the extrapolation from lower energies. The total pp cross-section has been determined in different ways from the extrapolation of the elasticscattering to t=0 (optical point and the inelastic rate: (i From the elastic scattering using the optical theorem and the CMS, (ii luminosity independently, usingthe inelastic rate, elastic scattering and the optical theorem, (iiiρ independently, by using elastic scattering, inelastic rate and the CMS luminosity. The results for the total crosssection obtained from the different methods are in excellent agreement with each other. First studies of the data on diffractive phenomena havebeen performed by correlating the momentum loss of the forward protons with the topology of the particle flux. The data look very promising and further studies will

    With the increase in center-of-mass energy, a new energy frontier has been opened by the Large Hadron Collider. More than 25 fb^-1 of proton-proton collisions at sqrt(s)=13 TeV have been delivered to both ATLAS and CMS experiments during 2016. This enormous dataset can be used to test the Standard Model in a complete new regime with tremendous precision and it has the potential to unveil new physics or set strong bounds on it. In this talk some of the most recent results made public by the CMS Collaboration will be presented. The focus will mainly be on searches for physics beyond the Standard Model, with particular emphasis on searches for dark matter candidates.

    During the year under report 1981, five working groups were active in the field of nuclear chemistry: neutron diffraction, radiation damage in solids, reactor chemistry, trace element research in bio-medicine and geo-chemistry. The objectives of the R+D projects ranged from the more basic research to the development of technological processes. Nuclear inspection methodes that have already been developed (e.g. neutron diffraction, trace element analysis) have increasingly been used in an interdisciplinary way. Besides these R+D projects the project of increase of power of the BER II was pursued also in 1981, and further planning documents on the extension of the BER II have been established. The report informs about the most important results of the single sections. A list of the publications (with abstracts) and lectures, also by guest scientists, is attached. (RB) [de

    1994-01-01

    Full Text Available Today the public is demanding that it exercise more control over how tax dollars are spent in the educational sphere, with multitudes also canvassing that education become closely aligned to the marketplace's economic forces. In this paper I examine an historical precedent for such demands, i.e. the comprehensive 19th century system of accountability, "Payment by Results," which endured in English and Welsh elementary schools from 1862 until 1897. Particular emphasis is focused on the economic market-driven aspect of the system whereby every pupil was examined annually by an Inspector, the amount of the governmental grant being largely dependent on the answering. I argue that this was a narrow, restrictive system of educational accountability though one totally in keeping with the age's pervasive utilitarian belief in laissez-faire. I conclude by observing that this Victorian system might be suggestive to us today when calls for analogous schemes of educational accountability are shrill.

    A precise knowledge of the cross section of nuclear fusion reactions is a crucial ingredient in understanding stellar evolution and nucleosynthesis. At stellar temperatures, fusion cross sections are extremely small and difficult to measure. Measuring nuclear cross sections at astrophysical energies is a challenge that triggered a huge amount of experimental work. A breakthrough in this direction was the first operation of an underground accelerator at the Laboratory for Underground Nuclear Astrophysics (LUNA) in Gran Sasso, Italy. The 1400 meters of rocks above the laboratory act as a natural shield against cosmic radiation, suppressing the background by orders of magnitude. The latest results achieved at LUNA are discussed, with special emphasis on the 22Ne(p,γ)23Na reaction. Future perspectives of the LUNA experiment are also illustrated.

    Full Text Available The HERMES experiment has collected a wealth of deep-inelastic scattering data using the 27.6 GeV polarized lepton beam at HERA and various pure gas targets, both unpolarized and polarized. This allowed for a series of diverse and unique measurements. Among them are measurements that provide information on the threedimensional structure of the nucleon, both in momentum space and in position space. Results of measurements of exclusive ω production on an unpolarized and transversely polarized nucleon target, sensitive to the distribution in transverse-position and longitudinalmomentum space, are discussed as well as the three-dimensional extraction of azimuthal asymmetries measured in semi-inclusive deep-inelastic scattering, sensitive to twist-2 and twist-3 distributions in three-dimensional momentum space.

    The PHOBOS detector is one of four heavy ion experiments at the Relativistic Heavy Ion Collider at Brookhaven National Laboratory. In this paper we will review some of the results of PHOBOS from the data collected in p+p, d+Au and Au+Au collisions at nucleon-nucleon center-of-mass energies up to 200 GeV. Evidence is found of the formation of a very high energy density and highly interactive system, which can not be described in terms of hadrons, and has a relatively low baryon density. There is evidence that the system formed is thermalized to a certain degree. Scaling with the number of participants and extended longitudinal scaling behavior are also observed in distributions of produced charged particles.

    The author deals with the experimental study of sorption, desorption and vertical migration of radionuclides in Sr-85 and Cs-137 in selected soil samples from around of NPP Bohunice and NPP Mochovce and other localities of the Slovakia. The influence of different materials [concurrent ions (K + , Ca 2+ , NH 4 + , pH), organic matter (peat) and zeolite, humidity] on kinetic of sorption and desorption of strontium and cesium as well as distribution coefficient (K D ) and transfer coefficients in followed samples of soils were followed. Obtained adsorption isotherm are presented and discussed. Using the Tessiere's sequential extraction analysis a gross variability in binding of radionuclides on soils was found. The obtained results were processed with the correlation analysis and the compartment model

    Areva's backlog established at 45.6 billion euros at the end of 2011, significantly increasing at the end of a year marked by the Fukushima accident, confirms the commercial dynamism of the group alongside its customers and reinforces the visibility on its future business level. In a difficult context, the slight decline in revenue in 2011 demonstrates the robustness of Areva's integrated model, resting mainly on recurring business generated in relation to Areva's customers' nuclear installed base, and benefiting from the development of Areva's renewable energies operations. Free operating cash flow before tax, although down over the whole year in 2011, improved in the second half, showing the first effects of Areva's stronger focus on cash generation and debt management. After the success of Areva's bond issue in September 2011, the Group's liquidity remains high at the end of 2011. The Areva teams are now dedicating all of their efforts to the deployment of the 'Action 2016' strategic action plan, which had already yielded its first positive results at the end of 2011, with an improvement in the cost structure of Areva's operations, an increase in order intake, and the launch of several disposals of minority interests. Summary of the 2011 financial results: - Backlog: euro 45.6 bn, +3.1% vs. 2010, i.e +6.7% over 3 months; - Revenue: euro 8.872 bn, i.e -2.6% vs. 2010; - Operating income: - euro 1.923 bn; - Net income attributable to equity owners of the parent: - euro 2.424 bn; - EBITDA: euro 1.068 bn ( euro 420 m excluding Siemens impact); - Free operating cash flow before tax: - euro 2.397 bn (- euro 1.366 bn excluding Siemens impacts), improvement over the second half; - Decrease in net debt of euro 124 m for the year; - Significant drop in general and administrative expenses, with a noticeable reduction between the first and the second half; - Launch of several disposals of minority interests

    This report discusses work being carried out in Norway to promote energy efficiency and the production of new renewable energy. An overall review of the quantifiable results of last year's activities at national level is available. It will serve to initiate an annual reporting tradition. The report represents a step towards an ongoing process for improved targeting and management of national efforts. During the course of the year 2000, NVE has evaluated and adjusted its activities and established a system involving indicators and reporting procedures. It is also important to take notice of the long-term work being undertaken to influence people's attitudes, even though this work is difficult to assess. NVE is investing in i.a. measures aimed at children and young people. Apart from directly influencing future energy users, this investment is also having an effect due to the children's encouragement of their parents to engage in more energy and environment-friendly behaviour. Published in 2000, the IEA report ''Trends in Norwegian Stationary Energy Use'' shows that total Norwegian energy consumption per GDP is not much higher than in other IEA countries, when adjusted for cold climate and industrial structure. However, Norwegians do stand out as intensive users of electricity. The IEA report shows a reduction of 10 TWh in energy usage when compared to the projected post 1990 figures. Energy efficiency activities have contributed towards this reduction. However, the potential for a more rational use of energy in Norway is still substantial and well documented. Based on experience most enterprises could save around 10% of energy used just by making changes to their operations, i.e. without major investments. Furthermore, the potential is growing because of massive technological developments in respect of energy usage, production and distribution. With this in mind, it is necessary to take full advantage of the extensive knowledge

    Local injections of the sclerosing substance polidocanol (Ethoxysclerol) have shown good clinical results in patients with chronic midportion Achilles tendinopathy. After training by the inventors of the technique, sclerosing Ethoxysclerol injections were applied on a group of patients in our center. Sclerosing Ethoxysclerol injections will yield good results in the majority of patients. Case series; Level of evidence, 4. In 113 patients (140 tendons) with Achilles tendinopathy, we identified 62 patients (70 tendons) showing neovascularization on color Doppler ultrasound. Fifty-three Achilles tendons (48 patients) were treated with sclerosing Ethoxysclerol injections, with intervals of 6 weeks and a maximum of 5 sessions. Treatment was completed when neovascularization or pain had disappeared, or when there was no positive treatment effect after 3 to 4 sessions. Forty-eight patients (20 women and 28 men) with a median age of 45 years, (range, 33-68 years) were treated. Median symptom duration was 23 months (range, 3-300 months). Fifty-three tendons were treated with a median of 3 sessions of Ethoxysclerol injections. Six weeks after the last injection, 35% of patients had no complaints, 9% had minimal symptoms, 42% were the same, and 14% had more complaints. Women were 3.8 times (95% confidence interval: 1.1-13.8) more likely to have unsatisfactory outcome than men. Pain correlated positively with neovessels on ultrasound (P < .01). At 2.7 to 5.1 year follow-up, 53% had received additional (surgical/conservative) treatment; 3 of these patients (7.5%) still had complaints of Achilles tendinopathy. In 6 patients, complaints that were still present 6 weeks after treatment had resolved spontaneously by final follow-up. Our study did not confirm the high beneficial value of sclerosing neovascularization in patients with midportion Achilles tendinopathy. Despite the retrospective design of our study, we consider it important to stress that injection of Ethoxysclerol may

    The follow-up data on 39 cases of stage I malignant melanoma treated with CO 2 laser are compared to those of an analogous group of cases treated by traditional surgical methods and selected for their clinical and pathologic similarities with the laser-treated group. The findings ware expressed in terms of tumor-free time and were evaluated by variance analysis. The data showed that traditional methods gave better results. CO 2 laser surgery requires longer headling time, which may have a negative effect on the course of the disease

    The results of the treatment of 28 patients with an anaplastic thyroid gland carcinoma are investigated, to see whether an optimal therapy is indicated. The execution of an operation before radiotherapy does not appear to improve the prognosis (statistically this conclusion is not wholly justified). The presence of metastases at the beginning of the therapy gave rise to a worse prognosis than the absence of metastases. The combination treatment of chemotherapy and either surgery or radiotherapy was only applied to two patients so no conclusions can be made about its benefit. (C.F.)

    We present 916 trigonometric parallaxes and proper motions of newly discovered nearby stars from the United States Naval Observatory Robotic Astrometric Telescope (URAT). Observations were taken at the Cerro Tololo Interamerican Observatory over a 2-year period from 2015 to 2017 October covering the entire sky south of about +25° decl. SPM4 and UCAC4 early epoch catalog data were added to extend the temporal coverage for the parallax and proper motion fit up to 48 years. Using these new URAT parallaxes, optical and near-IR photometry from the AAVSO Photometric All-Sky Survey and Two Micron All-Sky Survey catalogs, we identify possible new nearby dwarfs, young stars, low-metallicity subdwarfs and white dwarfs. Comparison to known trigonometric parallaxes shows a high quality of the URAT-based results confirming the error in parallax of the URAT south parallaxes reported here to be between 2 and 13 mas. We also include additional 729 trigonometric parallaxes from the URAT north 25 pc sample published in Finch & Zacharias here after applying the same criterion as for the southern sample to have a complete URAT 25 pc sample presented in this paper.

    Science.gov (United States)

    2016-08-01

    With recent developments of teleradiology technology and services, it has become necessary to better evaluate its extent and use among different countries in Europe. With this goal in mind, the ESR launched two specific surveys intended to gather the current state of adoption and implementation of teleradiology in clinical practice. A special focus on differentiating between insourcing teleradiology services among partners of the same organisation and outsourcing to external services was an essential part of the design of these surveys. The first survey was addressed to 44 national societies of different countries in Europe, while the second survey was intended for all practicing radiologist ESR members. While the results of these surveys reported here may provide a wealth of information to better understand the trends in adoption of teleradiology in Europe, they only represent a snapshot at a certain point in time. The rapid development of telecommunication tools as well as a fundamental change in practice and healthcare economics will certainly influence these observations in the upcoming years. These data, however, will provide objective and relevant parameters for supporting the efforts of experts and policy makers in promoting appropriate criteria and guidelines for adequate use of teleradiology in clinical practice. Main Messages • Understand concepts and challenges of teleradiology • Provide insight into current trends and solutions for teleradiology • Compare differences in teleradiolgy strategies between countries in Europe • Establish a reference on statistical data of usage of teleradiology in Europe.

    Just over a decade after identification of chemokine receptors CCR5 and CXCR4 as coreceptors for HIV, maraviroc (Celsentri), the first CCR5 antagonist, has recently obtained its Marketing Authorization in the United States and Europe, for treatment of treatment-experienced adult patients infected with only CCR5-tropic HIV-1 detectable. CCR5 antagonists, after fusion inhibitor enfuvirtide available since 2003, also belong to entry inhibitors. These molecules, unlike previous antiretrovirals, do not target the virus but its target cell by blocking viral penetration. Maraviroc has shown its clinical efficacy in patients failing other antiretroviral classes. Its safety profile was similar to placebo in two large phase III trials. However, careful assessment of both hepatic and immunologic safety of this new therapeutic class is needed. Viral tropism testing has to be investigated before using maraviroc in the clinic, because CCR5 antagonists are not active against CXCR4 viruses. For the moment indicated for the treatment-experienced patient population, maraviroc could in the future benefit to other types of patients, depending on ongoing trials results.

    This paper summarizes the results from the COBE satellite mission. Nine years have passed since the launch of COBE and six years since the announcement of the discovery of cosmic microwave background anisotropies by the COBE DMR instrument. This is still a relatively short time to look back and understand the implications of COBE and the anisotropy discovery; however, this 3K Cosmology Conference provides some context. The Cosmic Background Explorer (COBE) satellite has made a major contribution to the field of cosmology and has help create the confidence and high level of interest that propels the field today. Two major CMB observations, the thermal spectrum of the CMB and the CMB anisotropies, plus a host of other observations and conclusions are the basis and a major but not exclusive portion of the legacy of COBE. The recent detection and observation of the cosmic infrared background (CIB) are also part of COBE close-quote s major contribution to cosmology. copyright 1999 American Institute of Physics

    Full Text Available Purpose: Dysphagia is a common initial presentation in locally advanced esophageal cancer and negatively impacts patient quality of life and treatment compliance. To induce fast relief of dysphagia in patients with potentially operable esophageal cancer high-dose-rate (HDR brachytherapy was applied prior to definitive radiochemotherapy. Material and methods : In this single arm phase II clinical trial between 2013 to 2014 twenty patients with locally advanced esophageal cancer (17 squamous cell and 3 adenocarcinoma were treated with upfront 10 Gy HDR brachytherapy, followed by 50.4 Gy external beam radiotherapy (EBRT and concurrent chemotherapy with cisplatin/5-fluorouracil. Results : Tumor response, as measured by endoscopy and/or computed tomography scan, revealed complete remission in 16 and partial response in 4 patients (overall response rate 100%. Improvement of dysphagia was induced by brachytherapy within a few days and maintained up to the end of treatment in 80% of patients. No differences in either response rate or dysphagia resolution were found between squamous cell and adenocarcinoma histology. The grade 2 and 3 acute pancytopenia or bicytopenia reported in 4 patients, while sub-acute adverse effects with painful ulceration was seen in five patients, occurring after a median of 2 months. A perforation developed in one patient during the procedure of brachytherapy that resolved successfully with immediate surgery. Conclusions : Brachytherapy before EBRT was a safe and effective procedure to induce rapid and durable relief from dysphagia, especially when combined with EBRT.

    The Sudbury Neutrino Observatory (SNO) is an underground heavy water Cherenkov detector for studying solar neutrinos. SNO is capable of performing both flavor sensitive and flavor blind measurements of the solar neutrino flux. The first charged current (CC) measurement is found to be: ψ SNO CC (ν e ) = 1.75 ± 0.07(stat.) -0.11 +0.12 (sys.) ± 0.05 (theor.) x 10 6 cm -2 s -1 and the elastic scattering fluxes (ES) is: ψ SNO ES (ν x ) = 2.39 ± 0.34(stat.) -0.14 +0.16 (sys.) x 10 6 cm -2 s -1 . The ψ SNO CC (ν e ) result, when combined with the high statistics elastic scattering (ES) measurement from Super-Kamiokande, provide a strong evidence for solar neutrino flavor transformation (3.3σ). The deduced total solar neutrino flux is in good agreement with standard solar model predictions. No significant distortion in the energy spectrum is observed

    Recent results from VENUS experiments on e + e - reactions at energies between 52 and 60.8 GeV are presented. The R-values, the ratio of the total hadronic cross section to that of μ pair production, look slightly high within the present energy region. To understand this observation, a detailed study was carried out on the production of a heavy quark with |Q|=e/3. By using a next-to-leading log. approximation, the QCD cut-off parameter, Λ MS , was obtained as being Λ MS =208 MeV(+80MeV, -62MeV). The differential cross sections for e + e - → e + e - , γγ, μ + μ - , and τ + τ - were found to be consistent with predictions of the standard model. The average charge asymmetry for e + e - → qq-bar was also measured and found to be consistent with the prediction of the standard model. No evidence was observed indicating new particle production. No single photon production was observed and the upper limit of the number of light neutrino types was set to be N ν < 17.8 (90 % CL). (author)

    2016-04-01

    MAGIC is a system of two 17-m diameter Cherenkov telescopes, located at the Observatorio del Roque de los Muchachos, in the Canary island La Palma (Spain). MAGIC performs astronomical observations of gamma-ray sources in the energy range between 50 GeV and 10 TeV. The first MAGIC telescope has been operating since 2004, and in 2009 the system was completed with the second one. During 2011 and 2012 the electronics for the readout system were fully upgraded, and the camera of the first telescope replaced. After that, no major hardware interventions are foreseen in the next years, and the experiment has undertaken a final period of steady astronomical observations. MAGIC studies particle acceleration in the most violent cosmic environments, such as active galactic nuclei, gamma-ray bursts, pulsars, supernova remnants or binary systems. In addition, it addresses some fundamental questions of Physics, such as the origin of Galactic cosmic rays and the nature of dark matter. Moreover, by observing the gamma-ray emission from sources at cosmological distances, we measure the intensity and evolution of the extragalactic background radiation, and perform tests of Lorentz Invariance. In this paper I present the status and some of the latest results of the MAGIC gamma-ray telescopes.

    The LHCf experiment has taken data in 2009 and 2010 p-p collisions at LHC at $\\sqrt{s} = 0.9$ TeV and $\\sqrt{s} = 7$ TeV. The measurement of the forward neutral particle spectra produced in proton-proton collisions at LHC up to an energy of 14 TeV in the center of mass system are of fundamental importance to calibrate the Monte Carlo models widely used in the high energy cosmic ray (HECR) field, up to an equivalent laboratory energy of the order of $10^{17}$ eV. In this paper the first results on the inclusive photon spectrum measured by LHCf is reported. Comparison of this spectrum with the model expectations show significant discrepancies, mainly in the high energy region. In addition, perspectives for future analyses as well as the program for the next data taking period, in particular the possibility to take data in p-Pb collisions, will be discussed.

    The Lawrence Livermore Laboratory (LLL), as part of the Nevada Nuclear Waste Storage Investigations (NNWSI) program, is carrying out in situ rock mechanics testing in the Climax granitic stock at the Nevada Test Site (NTS). This summary addresses only those field data taken to date that address thermomechanical modeling for a hard-rock repository. The results to be discussed include thermal measurements in a heater test that was conducted from October 1977 through July 1978, and stress and displacement measurements made during and after excavation of the canister storage drift for the Spent Fuel Test (SFT) in the Climax granite. Associated laboratory and field measurements are summarized. The rock temperature for a given applied heat load at a point in time and space can be adequately modeled with simple analytic calculations involving superposition and integration of numerous point source solutions. The input, for locations beyond about a meter from the source, can be a constant thermal conductivity and diffusivity. The value of thermal conductivity required to match the field data is as much as 25% different from laboratory-measured values. Therefore, unless we come to understand the mechanisms for this difference, a simple in situ test will be required to obtain a value for final repository design. Some sensitivity calculations have shown that the temperature field is about ten times more sensitive to conductivity than to diffusivity under the test conditions. The orthogonal array was designed to detect anisotropy. After considering all error sources, anisotropic efforts in the thermal field were less than 5 to 10%.

    The scale of the net loss for 2014 illustrates the twofold challenge confronting AREVA: continuing stagnation of the nuclear operations, lack of competitiveness and difficulties in managing the risks inherent in large projects. The group understands how serious this situation is. A comprehensive strategic review of operations was undertaken beginning in November 2014 and is being carried out without compromise. As a result, AREVA is now able to announce a solid transformation plan that sets a challenging but economically realistic course for its teams. First, AREVA will refocus on its core business: mastery of key nuclear processes essential to operators around the globe. This strategic redeployment will lead to the revision of certain goals, whether in the management of new reactor projects or in renewable energies. AREVA's objective is to achieve excellence as a high value-added supplier of products and services. Secondly, AREVA, whose resources had been marshaled to support a spurt of growth in nuclear power, must now adapt to new market realities and become competitive once again. The group's most urgent task is recovery and securing its future by immediately launching a far-reaching competitiveness plan founded on organizational simplification, quality of operations, and a completely revamped approach to managing risk in large projects. Last but not least, AREVA must ensure sustainable financing for its activities. A financing plan will be clarified before publication of the half-year financial statements. This document presents the key financial data of the group, its strategic road-map and its operating and financing plans

(b) Determined vertical positional instability growth rates for passively stabilized elongated dee-shaped plasmas with surface elongations from 1 to 1.4. (c) Production of Z approximately equal to 1 plasmas in a diverted dee configuration with confinement times approaching 80 ms for plasmas with Isub(p) approximately equal to 300 kA, Bsub(T)=17 kG, a=38 cm, q approximately equal to 3 and anti nsub(e) approximately equal to 4x10 13 cm -3 . (d) Extended the Ohmic heating regime to q approximately equal to 2 at nsub(e)R/Bsub(T) approximately equal to 10 15 cm -2 T -1 and q approximately equal to 3 at anti nsub(e)R/Bsub(T) approximately equal to 4.5x10 15 cm -2 T -1 . Neutral beam injection has extended anti nsub(e)R/Bsub(T) to approximately 6x10 15 cm -2 T -1 . (e) Initial neutral beam injection experiments with 1-2 MW injected perpendicularly have been used to study ion and electron heating with divertor control of density and impurities. (f) Divertor physics studies indicate that the divertor captures approximately 70% of the input power, while approximately 30% of the power is radiated. (g) Particle and energy flow onto the divertor neutralizer plate is in qualitative agreement with a simple sheath model. (author)

    The EUROASPIRE III audit was a Europe-wide study which took place in 2006\\/2007. The objective was to examine the control of risk factors in subjects with established cardiovascular disease. Here, we compare the Irish results to those of the other 21 European countries which participated. Control of blood cholesterol was significantly better in Irish participants, with 73% below the target of 4.5 mmol\\/l. Blood pressure control was less satisfactory in both Irish and European individuals, with an average of 52% of Irish participants not achieving blood pressure targets. Medication usage was high throughout, particularly anti-platelet agents, beta-blockers and, especially in Ireland, statins. Obesity figures were particularly high in Ireland and throughout Europe, with 82% Irish men and women either overweight or obese. Smoking figures in Irish women were also of concern, with 24% continuing to smoke. Cardiac rehabilitation attendance was particularly high in Ireland, with 68% attending; substantially higher than the European figure of 34%. In common with the rest of Europe, current control of body weight and blood pressure in Ireland is unsatisfactory and in need of increased consideration on the part of both patients and healthcare professionals.

    AREVA expanded its backlog and increased its revenues compared with 2008, on strong installed base business and dynamic major projects, fostering growth in operating income of 240 million euros. As announced previously, Areva is implementing a financing plan suited to its objectives of profitable growth. The plan was implemented successfully in 2009, including the conclusion of an agreement, under very satisfactory terms, to sell its Transmission and Distribution business for 4 billion euros, asset sales for more than 1.5 billion euros, and successful bond issues of 3 billion euros. The plan will continue in 2010 with a capital increase, the completion of asset disposals and cost reduction and continued operational performance improvement programs. Areva bolstered its Renewable Energies business segment by supplementing its offshore wind power and biomass businesses with the acquisition of Ausra, a California-based leader in concentrated solar power technology. Despite the sale of T and D, Areva is maintaining its financial performance outlook for 2012: 12% average annual revenue growth to 12 billion euros in 2012, double digit operating margin and substantially positive free operating cash flow. Annual results 2009: - For the group as a whole, including Transmission and Distribution: Backlog: euros 49.4 bn (+2.5%), Revenues: euros 14 bn (+6.4%), Operating income: euros 501 m (+20.1%); - Nuclear and Renewable Energies perimeter: Backlog: euros 43.3 bn (+1.8%), Strong revenue growth: +5.4% to euros 8.5 bn, Operating income before provision for the Finnish project in the first half of 2009: euros 647 m, Operating income: euros 97 m, for a euros 240 m increase from 2008; - Net income attributable to equity holders of the parent: euros 552 m, i.e. euros 15.59 per share; - Net debt: euros 6,193 m; - Pro-forma net debt, including net cash to be received from the sale of T and D in 2010: euros 3,022 m; - Dividend of euros 7.06 per share to be proposed during the Annual

    field. Early edge localized mode activity on MAST is associated with the formation of narrow filamentary structures following field lines in the edge. These filaments rotate toroidally with the edge plasma and, away from the X-points, accelerate radially outwards from the edge up to 20 cm. Studies of disruptions on MAST demonstrate a complex evolution of core energy loss and resultant divertor power loads, including phases where the target heat flux width is broadened by a factor of 8. Observations of energetic particle modes driven by super-Alfvenic beam ions provide support for a model for the non-linear evolution of toroidal Alfven eigenmodes (AEs) forming Bernstein-Green-Krushal waves. The AE activity reduces to low levels with increasing β. Plasma start-up without a central solenoid and in a manner compatible with future large spherical tokamak (ST) devices has been demonstrated using breakdown at a quadrupole magnetic null. Closed flux surface plasmas with peak plasma currents up to 370 kA have been generated and sustained for 0.3 s. New error field correction coils have extended the operational space for low density plasmas and enabled scaling studies of error field induced locked mode formation in the ST

Given its 'sticky' quality, DDT is difficult to isolate and treat in the solid matrix of soil. “Our ViroFlow Technology has been designed to overcome both these problems by using a chemical, not bacterial, agent and by separating DDT from the structure of the soil matrix, thereby making it vulnerable to decomposition,” said Barros. As a result of these findings, Virotec is conducting a series of tests in conjunction with the NSW EPA and Department of Primary Industries to examine ways its solution can be applied to treating DDT in soil.

    The transport of sediments by water throughout the river basins, from the steep slopes of the upstream regions to the sea level, is recognizable important to keep the natural conditions of rivers with a role on their ecology processes. Over the last decades, a reduction on the supply of sand and gravel has been observed downstream dams existing in several alpine rivers. Many studies highlight that the presence of a dam strongly modifies the river behavior in the downstream reach, in terms of morphology and hydrodynamics, with consequences on local ecology. Sediment deficit, bed armoring, river incision and bank instability are the main effects which affect negatively the aquatic habitats and the water quality. One of the proposed techniques to solve the problem of sediment deficit downstream dams, already adopted in few Japanese and German rivers although on an unsatisfactory fashion, is the artificial replenishment of these. Generally, it was verified that the erosion of the replenishments was not satisfactory and the transport rate was not enough to move the sediments to sufficient downstream distances. In order to improve and to provide an engineering answer to make this technique more applicable, a series of laboratory tests are ran as preparatory study to understand the hydrodynamics of the river flow when the replenishment technique is applied. Erodible volumes, with different lengths and submergence conditions, reproducing sediment replenishments volumes, are positioned along a channel bank. Different geometrical combinations of erodible sediment volumes are tested as well on the experimental flume. The first results of the experimental research, concerning erosion time evolution, the influence of discharge and the distance travelled by the eroded sediments, will be presented and discussed.

    Full Text Available The paper focuses on the results of physiological research performed on 9 occupational groups of migrants who came to Moscow region of Russia from southern Central Asia republics. We studied adaptation processes characteristics in labor migrants as per cardiovascular system parameters and neuromuscular apparatus parameters. We revealed peculiarities in heart rate variability (changes in stress index S1, values of AMo, VLF spectrum power, PARS parameter in migrants de-pending on neuro-emotional nature of working activity and muscular loads intensity. We detected apparent decrease in dynamometric parameters of endurance and maximum working capacity of arms muscles and backbones and legs muscles by the end of their working day. We created a procedure to determine an adaptation process stage under combined effects ex-erted by labor physical hardness and neuro-emotional intensity; unsatisfactory adaptation increases health disorders risks. We showed that long-term and intense impacts by factors determining labor process hardness caused occupational diseases of musculoskeletal system and peripheral nervous system. We revealed that as labor intensity grew working stress in a body also increased and it could transform into overstrain and occupational diseases evolvement (primary hypertension, ischemic heart diseases, and neurotic disorders. A distinctive feature is that men suffer from cardiovascular system pathologies more frequently while women tend to suffer from nervous system pathologies. In this relation, we should make separate predictions of occupational pathology probability depending on labor intensity level for males and females. Adaptation processes optimization should include organization of rational work and rest regime, healthy lifestyle for-mation, improvements in medical aid for migrants.

    The search for an optimal patch material for aortic valve reconstruction (AVR) is an ongoing challenge. In this study, we report our experience of AVR using decellularized bovine pericardial patch material in congenital heart surgery. Data of 40 consecutive patients who underwent AVR using the CardioCel® patch (Admedus Regen Pty Ltd, Perth, WA, Australia) between February 2014 and August 2016 were retrospectively reviewed. The median age of the patients at operation was 9 (2-34) years, and 18 patients were younger than 7 years. Twenty-six patients initially presented with aortic valve insufficiency (AI) and 14 with stenosis. Clinical and echocardiographic data were available until August 2017 for a median postoperative follow-up (FU) of 22 (6-42) months. Nine of 40 (23%) patients experienced an event during FU (death: n = 1, 2.5%; reoperation: n = 8, 20%). Overall, the probability of freedom from reoperation or death was 97 ± 3%, 76 ± 9% and 57 ± 12% at 12, 24 and 36 months of FU, respectively. Reason for reoperation was stenosis in 3 (37.5%) patients, insufficiency in 4 (50%) patients and 1 (12.5%) patient was diagnosed with aortic valve endocarditis. Of the remaining 31 patients, 2 patients are scheduled for reoperation (aortic valve stenosis: n = 1 and AI: n = 1) and 9 patients exhibit worsening of aortic valve function with moderate AI.

    Differences of crystallographic texture of zircaloy-4 plate depends on cold working and heat treatment.To determine the change of zircaloy-4 textures, the solid solution treatment process at beta phase which was followed by quenching on water was employed for this sample. The next step was cold rolling until deformation epsilon = 1.62. The specimens were recrystallized at 750 o C, for 2 hours. The result of beta-quench gave a spread and different orientations and the main orientation occurred at (0001)[1010] and (0001)[1120]. Result of cold rolling with epsilon = 1.39 and epsilon 1.62 is the deformation texture at the main orientation of (0001)[1010] with the angle of inclination was around 38 o. However, the result of Recrystallization process on 750 o C for 2 hours gave annealing textures with orientations of (0001)[1120]. It means that the recrystallization process of zircaloy-4 plate can not remove the deformation textures, but can change the crystallographic orientation

    Full Text Available Abstract Background Early diagnosis and referral to treatment prior to age 3–5 years improves the prognosis of children with Autism Spectrum Disorder (ASD. However, ASD is often not diagnosed until age 3–4 years, and medical providers may lack training to offer caregivers evidence-based treatment recommendations. This study tested hypotheses that 1 children with ASD would be diagnosed between ages 3–4 years (replicating prior work, 2 caregivers would receive little information beyond the diagnosis from their medical providers, and 3 caregivers would turn to other sources, outside of their local health care professionals, to learn more about ASD. Methods 146 ASD caregivers responded to an online survey that consisted of questions about demographics, the diagnostic process, sources of information/support, and the need and availability of local services for ASDs. Hypotheses were tested using descriptives, regression analyses, analyses of variance, and chi-squared. Results The average age of diagnosis was 4 years, 10 months and the mode was 3 years. While approximately 40% of professionals gave additional information about ASD after diagnosis and 15–34% gave advice on medical/educational programs, only 6% referred to an autism specialist and 18% gave no further information. The diagnosis of Autism was made at earlier ages than Asperger's Disorder or PDD-NOS. Developmental pediatricians (relative to psychiatrists/primary care physicians, neurologists, and psychologists were associated with the lowest age of diagnosis and were most likely to distribute additional information. Caregivers most often reported turning to the media (i.e., internet, books, videos, conferences, and other parents to learn more about ASD. Conclusion The average age of ASD diagnosis (4 years, 10 months was later than optimal if children are to receive the most benefit from early intervention. Most professionals gave caregivers further information about ASDs, especially

    In membrane process industries, membrane cleaning is one of the most important concerns from both economical and scientific points of view. Though cleaning is important to recover membrane performance, an inappropriate selection of cleaning agents may result into unsatisfactory cleaning or irreparable membrane. In this study the cleaning performance has been studied with measurements of membrane contact angle, Updated Donnan steric partitioning pore model (UDSPM) and salt rejection as well as flux measurement. Thin film nanofiltration (NF) membranes such as DK, HL and DL provided by GE Osmonics are used in this study. Tests were carried out with virgin DK, HL and DL as well as fouled DK membranes. Several cleaning agents were investigated; some of them were analytical grade such as HCl, NaOH and others such as SDS, mix agents were commercial grade agents that are already in use in commercial plants. Contact angle, DSPM and salt rejection as well as flux of virgin and fouled membranes before and after chemical cleaning were measured and compared. The contact angle measurements with and without chemical cleaning of different virgin and fouled membranes revealed very interesting results which may be used to characterise the membrane surface cleanliness. The contact angle results revealed that the cleaning agents are found to modify membrane surface properties (hydrophobicity/hydrophilicity) of the treated and untreated virgin and fouled membranes. The details of these results were also investigated and are reported in the paper. However, UDSPM method did not give any valuable information about pore size of the untreated and treated NF membranes. The salt rejection level of monovalent and divalent ions before and after cleaning by high and low pH cleaning agents is also investigated and is reported in the paper

    Depending on the method used, rare sequence variants adjacent to the single nucleotide polymorphism (SNP) of interest may cause unusual or erroneous genotyping results. Because such rare variants are known for many genes commonly tested in diagnostic laboratories, we organized a proficiency study to assess their influence on the accuracy of reported laboratory results. Four external quality control materials were processed and sent to 283 laboratories through 3 EQA organizers for analysis of the prothrombin 20210G>A mutation. Two of these quality control materials contained sequence variants introduced by site-directed mutagenesis. One hundred eighty-nine laboratories participated in the study. When samples gave a usual result with the method applied, the error rate was 5.1%. Detailed analysis showed that more than 70% of the failures were reported from only 9 laboratories. Allele-specific amplification-based PCR had a much higher error rate than other methods (18.3% vs 2.9%). The variants 20209C>T and [20175T>G; 20179_20180delAC] resulted in unusual genotyping results in 67 and 85 laboratories, respectively. Eighty-three (54.6%) of these unusual results were not recognized, 32 (21.1%) were attributed to technical issues, and only 37 (24.3%) were recognized as another sequence variant. Our findings revealed that some of the participating laboratories were not able to recognize and correctly interpret unusual genotyping results caused by rare SNPs. Our study indicates that the majority of the failures could be avoided by improved training and careful selection and validation of the methods applied.

    A well-known problem with student surveys is a too low response rate. Experiences with predicting electoral outcomes, which required much smaller sample sizes, inspired us to adopt a similar approach to course evaluation. We expected that having respondents estimate the average opinions of their peers required fewer respondents for comparable outcomes than giving own opinions. Two course evaluation studies were performed among successive first-year medical students (N = 380 and 450, respectively). Study 1: Half the cohort gave opinions on nine questions, while the other half predicted the average outcomes. A prize was offered for the three best predictions (motivational remedy). Study 2: Half the cohort gave opinions, a quarter made predictions without a prize and a quarter made predictions with previous year's results as prior knowledge (cognitive remedy). The numbers of respondents required for stable outcomes were determined following an iterative process. Differences between numbers of respondents required and between average scores were analysed with ANOVA. In both studies, the prediction conditions required significantly fewer respondents (p < 0.001) for comparable outcomes. The informed prediction condition required the fewest respondents (N < 20). Problems with response rates can be reduced by asking respondents to predict evaluation outcomes rather than giving opinions.

  12. New results on CP violation in the charm sector

    2013-01-01

    The difference in CP violation between the D0→K+K– and D0→π+π– decays (ΔACP) has emerged as an interesting observable to search for matter-antimatter asymmetries in the charm sector. By taking the difference between the two modes, most of the asymmetries induced by the detector or coming from the production mechanism cancel. A previous LHCb measurement, using 0.6 fb–1 of data, gave 3.5σ evidence for CP violation in the charm sector, which was further strengthened by results from the CDF and Belle collaborations. We present an update of the ΔACP measurement, consisting of two independent analyses, both using the full 2011 data set of 1.0 fb–1. In the first, the initial flavour of the D meson (D0 or D0-bar) is inferred from the charge of the slow pion in the decay D*+→D0π+, as in the previous publication. The second uses D mesons produced in semileptonic B decays, where the charge of the associated muon provides the tag.

    The National Comprehensive Cancer Network clinical practice guidelines in oncology-gastric cancer guidelines have been widely used to provide appropriate recommendations for the treatment of patients with gastric cancer. The aim of this study was to examine the adherence of surgical oncologists, medical oncologists, and radiation oncologists' to the recommended guidelines. A questionnaire asking the treatment options for gastric cancer cases was sent to 394 Chinese oncology specialists, including surgical oncologists, medical oncologists, and radiation oncologists working in hospitals joined in The Western Cooperative Gastrointestinal Oncology Group of China. The questionnaire involved a series of clinical scenarios regarding the interpretation of surgery, neoadjuvant, adjuvant, and advanced treatment planning of gastric cancer. Analysis of 358 respondents (91%) showed variations between each specialization and from the recommended guidelines in the management approaches to specific clinical scenarios. The majority of specialists admitted that less than 50% of patients received multidisciplinary evaluation before treatment. The participants gave different responses to questions involving adjuvant, neoadjuvant, and advanced settings, compared to the recommended guidelines. These results highlight the heterogeneity of the treatment of gastric cancer. Surgical oncologists, medical oncologists, and radiation oncologists are not adhering to the recommended guidelines

    2017-01-01

    This essay explores representations of Africa in the three primary U.S. homophile periodicals of the 1950s and early 1960s. It considers 130 articles, letters, and stories in Mattachine Review, ONE, and The Ladder that mentioned Africa or Africans. In doing so, it explores and analyzes the ways that Africa was referenced and represented to understand how those periodicals, their writers, and the U.S. homophile movement understood and were influenced by Africa (or by their perceptions of Africa). The essay argues that views expressed in The Ladder, Mattachine Review, and ONE reflected broader thinking about Africa in the 1950s and early 1960s in focusing on Egypt, relying on U.S. accounts of Africa, and eroticizing the bodies of Africans. But homophile publications also differed from their mainstream counterparts by presenting various African cultures as superior to U.S. culture in their liberal views of and approaches to sexual and gender variance.

    1996-05-01

    This paper presents the results of an international intercomparison of photovoltaic (PV) performance measurements and calibrations. The intercomparison, which was organized and operated by a group of experts representing national laboratories from across the globe (i.e., the authors of this paper), was accomplished by circulating two sample sets. One set consisted of twenty silicon reference cells that would, hopefully, form the basis of an international PV reference scale. A qualification procedure applied to the calibration results gave average calibration numbers with an overall standard deviation of less than 2% for the entire set. The second set was assembled from a wide range of newer technologies that present unique problems for PV measurements. As might be expected, these results showed much larger differences among laboratories. Methods were then identified that should be used to measure such devices, along with problems to avoid.

  19. Effects of thermocouple installation and location on fuel rod temperature measurements

    1983-01-01

    This paper describes the results of analyses of nuclear fuel rod cladding temperature data obtained during in-reactor experiments under steady state and transient (simulated loss-of-coolant accident) operating conditions. The objective of the analyses was to determine the effect of thermocouple attachment method and location on measured thermal response. The use of external thermocouples increased the time to critical heat flux (CHF), reduced the blowdown peak temperature, and enhanced rod quench. A comparison of laser welded and resistance welded external thermocouple responses showed that the laser welding technique reduced the indicated cladding steady state temperatures and provided shorter time-to-CHF. A comparison of internal welded and embedded thermocouples indicated that the welded technique gave generally unsatisfactory cladding temperature measurements. The embedded thermocouple gave good, consistent results, but was possibly more fragile than the welded thermocouples. Detailed descriptions of the thermocouple designs, attachment methods and locations, and test conditions are provided

    The objective of this study was to compare cervical high-grade squamous intraepithelial lesions subcategorized as cervical intraepithelial neoplasia-3 (CIN-3)-positive after a negative cytology result but positive for high-risk human papillomavirus (HR-HPV) testing to those with a negative HR-HPV test but positive cytology (atypical squamous cells of undetermined significance [ASCUS]-positive/HPV-negative) and to assess reasons for discrepancies. The authors retrospectively analyzed women who underwent screening with cytology and HPV testing from 2010 through 2013. After a review of surgical specimens and cytology, discrepancies were classified as sampling or interpretation error. Clinical and pathologic findings were compared. In total, 15,173 women (age range, 25-95 years; 7.1% were aged ASCUS-positive/HPV-positive, 11 that tested negative for intraepithelial lesion or malignancy (NILM)/HPV-positive, 10 that tested ASCUS-positive/HPV-negative, 3 that tested NILM/HPV-negative, and 5 tests that were unsatisfactory. There was no significant difference between NILM/HPV-positive and ASCUS-positive/HPV-negative CIN-3 in terms of size, time to occurrence, the presence of a cytopathic effect, screening history, race, or age. Six of 11 NILM/HPV-positive cases were reclassified as ASCUS, indicating an interpreting error of 55% and a sampling error of 45%. No ASCUS-positive/HPV-negative cases were reclassified. Seven cases of CIN-3 with positive cytology were HPV-negative. There are no significant clinical or pathologic differences between NILM/HPV-positive and ASCUS-positive/HPV-negative CIN-3-positive specimens. Cytologic sampling or interpretation remains the main reason for discrepancies. However, HPV-negative CIN-3 with positive cytology exists and may be missed by primary HPV screening.

    1992-10-01

    The interest of surgical prostheses in the palliative treatment of biliary tract cancer is well established, on the basis of their good tolerance, the more than 15 year follow up experience and the number of patients operated upon. After exeresis, they allow re-establishment of continuity, either by use of a prosthesis in Y when the right and let ducts can be dissected, or by using two prostheses, a multiperforated long prosthesis reimplanted in the duodenum and a short prosthesis reimplanted in the common bile duct without attaining the sphincter of Oddi. Of the 1000 cases treated, 500 were the object of a statistical analysis, 46 being operated upon by the author, in 60% of cases for biliary tract cancer, either primary or as an extension from the gallbladder. One-third of the patients had advanced lesions and a short survival of less than 3 months. Two-thirds a median survival of 9 months. In 10%, a radical exeresis was performed with survival of more than one year without recurrence of jaundice. Failure of treatment with persistence of jaundice was due to advanced disease for which surgery is unsatisfactory. Essential complications were premature bile leaks (5%) without serious consequences if sufficient drainage was maintained, since it stopped spontaneously, and angiocholitis (6%), the result of territory exclusion or reflux. Recurrence of jaundice was related to extension of the neoplasm to the secondary bile ducts, and to hepatic metastases. Obstruction of the prosthesis before two months was rare (6%) and was preceded by angiocholitis. In the absence of recurrence of the cancer the prosthesis can be replaced surgically without difficulty.

    An improved bioassay for fluconazole was developed. This assay is sensitive in the clinically relevant range (2 to 40 micrograms/ml) and analyzes plasma, serum, and cerebrospinal fluid specimens; bioassay results correlate with results obtained by high-pressure liquid chromatography (HPLC). Bioassay and HPLC analyses of spiked plasma, serum, and cerebrospinal fluid samples (run as unknowns) gave good agreement with expected values. Analysis of specimens from patients gave equivalent results by both HPLC and bioassay. HPLC had a lower within-run coefficient of variation (less than 2.5% for HPLC versus less than 11% for bioassay) and a lower between-run coefficient of variation (less than 5% versus less than 12% for bioassay) and was more sensitive (lower limit of detection, 0.1 micrograms/ml [versus 2 micrograms/ml for bioassay]). The bioassay is, however, sufficiently accurate and sensitive for clinical specimens, and its relative simplicity, low sample volume requirement, and low equipment cost should make it the technique of choice for analysis of routine clinical specimens.

    To determine the five-year success rates, site or sites of failure, prognostic indicators and lower lip morbidity associated with molar apicectomy using amalgam root-end filling. Multicentre, prospective study. The departments of oral and maxillo-facial surgery in two district general hospitals. One thousand and seven molar apicectomy procedures, combined with amalgam root-end filling were expedited during the period 1974-1995. A five-year review of each operated tooth was carried out or attempted between 1979-2000. Of the 790 (78%) operated molars successfully reviewed at 5 years or later 451 (57%) exhibited 'complete healing' and 39 (5%) 'uncertain healing'. Three hundred (38%) were classified as 'unsatisfactory healing' (failures), and these included 12 which were assumed to be of periodontal origin. Whilst longitudinal root fracture, perforation and/or infection in the furcation, periodontal disease or a non-restorable crown accounted for treatment failure and often the need to remove teeth subsequently, the study probably pointed to the apical ends of the roots rather than the furcation as being the major sites at which 'unsatisfactory healing' occurred. Mandibular first molars attracted the highest 'complete healing' rate (60%) and mandibular second molars the lowest (46%). 'Good' root canal treatment (RCT) at the outset improved the prognosis of a root-end filling (REF) whilst the absence of RCT compromised it. Cystic change pointed to a better prognosis than apical granulomatous change as did a deep compared with a shallow 'bone cuff'. Disease at the furcation suggested a worse prognosis. Teeth which showed 'complete healing' at 1 year had a 75% probability of maintaining this outcome at 5 years. Sensory disturbance of variable duration occurred in the lower lip following 20-21% of mandibular molar procedures. In the majority of cases (79-80%) this had remitted within 3 months. A permanent deficit occurred in 8 patients (1%) where the apicectomy could

  7. Aesthetic rhinoplasty: Avoiding unfavourable results

    2013-01-01

    Full Text Available Rhinoplasty is one of the most challenging surgical procedures in plastic surgery. It is not surprising that a significant number of patients end up with unfavourable outcomes. Many of these unfavourable outcomes could be the result of poor judgment and wrong decision making. Most frequently, the unfavourable outcome is the result of errors in surgical technique. In this paper, unfavourable outcomes resulting from errors in surgical technique are discussed under the heading of each operative step. Poor placement of intra-nasal incision can result in internal valve obstruction. Bad columellar scars can result from errors during open rhinoplasty. Unfavourable results associated with skeletonisation are mentioned. Tip plasty, being the most difficult part of rhinoplasty, can result in lack of tip projection, asymmetry and deformities associated with placement of tip grafts. Over-resection of the lower lateral cartilages during tip plasty can also result in pinched nose, alar collapse causing external valve obstruction and other alar rim deformities. Humpectomy can result in open roof deformity, inverted V deformity and over-resection resulting in saddle nose. The so-called poly beak deformity is also a preventable unfavourable outcome when dealing with a large dorsal hump. Complications resulting from osteotomies include narrowing of nasal airway, open roof deformity, inverted V deformity and asymmetry of the bony wall resulting from incomplete or green stick fractures. Judicious use of grafts can be very rewarding. By the same token, grafts also carry with them the risk of complications. Allografts can result in recurrent infection, atrophy of the overlying skin and extrusion resulting in crippling deformities. Autografts are recommended by the author. Unfavourable results from autografts include displacement of graft, visibility of the graft edges, asymmetry, warping, and resorption.

    Well-defined protocols and quality management standards are indispensable for biological dosimetry laboratories. Participation in periodic proficiency testing by interlaboratory comparisons is also required. This harmonization is essential if a cooperative network is used to respond to a mass casualty event. Here we present an international intercomparison based on dicentric chromosome analysis for dose assessment performed in the framework of the IAEA Regional Latin American RLA/9/054 Project. The exercise involved 14 laboratories, 8 from Latin America and 6 from Europe. The performance of each laboratory and the reproducibility of the exercise were evaluated using robust methods described in ISO standards. The study was based on the analysis of slides from samples irradiated with 0.75 (DI) and 2.5 Gy (DII). Laboratories were required to score the frequency of dicentrics and convert them to estimated doses, using their own dose-effect curves, after the analysis of 50 or 100 cells (triage mode) and after conventional scoring of 500 cells or 100 dicentrics. In the conventional scoring, at both doses, all reported frequencies were considered as satisfactory, and two reported doses were considered as questionable. The analysis of the data dispersion among the dicentric frequencies and among doses indicated a better reproducibility for estimated doses (15.6% for DI and 8.8% for DII) than for frequencies (24.4% for DI and 11.4% for DII), expressed by the coefficient of variation. In the two triage modes, although robust analysis classified some reported frequencies or doses as unsatisfactory or questionable, all estimated doses were in agreement with the accepted error of ±0.5 Gy. However, at the DI dose and for 50 scored cells, 5 out of the 14 reported confidence intervals that included zero dose and could be interpreted as false negatives. This improved with 100 cells, where only one confidence interval included zero dose. At the DII dose, all estimations fell within

    Unsatisfactory blood pressure (BP) control so often described in treated hypertensive populations is also explained by insufficient physicians' awareness of experts' guidelines. We assessed awareness of current recommendations about hypertension management in a general practice setting, using the World Health Organization/International Society of Hypertension (WHO/ISH) 1999 guidelines as reference. In a regionwide survey, a total of 5133 physicians (three-quarters of all active general practitioners in Lombardy, a region of north-western Italy) were contacted by letter and received a multiple choice 10-item questionnaire. Data on physicians' demographic characteristics, information on hypertension prevalence and their perception of BP control among their patients were also requested in an additional form. The number of answers in agreement with WHO/ISH guidelines was used as an awareness measure. This was considered adequate if correct answers to six out of 10 questions, including an appropriate definition of hypertension, were provided. Of the 1256 returned questionnaires (a 24.5% response rate), 1162 were suitable for analysis. The mean score of correct answers was 5.3 points and only 20.1% of the study population correctly answered at least six of the questions (including that on the definition of hypertension in the elderly). Guidelines awareness was negatively related to increase in physicians' age and duration of clinical practice and by the male gender. Finally, the physicians reported a high rate of achieved BP control, and those who were considered to have achieved highest rates (>75%) of control in their patients had a lower rate of adequate knowledge than those who reported less-successful therapeutic results (18 vs 25%, P<0.01), suggesting that they ignored or disregarded the goal BP recommended by the guidelines. This large regional survey shows that a sufficient degree of guidelines awareness is present in a minority of primary-care physicians in the

    The general public not engaged in the nuclear power plant industry have no idea of the color usage in the nuclear control room. So we converted the specific color usage situation into similar but general situations. In questionnaire, we gave subjects the general situation where color coding is applied and alternative colors which were applied to the HF010 guidelines. And we asked the subjects to choose the colors proper to the situation and to rank the colors according to the degree of suitability. Two hundred fifty college students participated in the experiment. The results suggest that we can use any color coding system in the conventional control room and the CRT in the control deck because most people have no special previous color-meaning association but red-emergency relation.

    The CEA analysis of the 1995 benchmark test has been focused on the location of the injections. Two techniques have been tested: the pulse timing technique, and the time-domain delay and sum beamforming technique. The two methods gave coherent locations of the injector even if there was a difference of 25% of the SGU height between the vertical locations. Prior to that analysis, the RMS values of the signals were calculated in different frequency bands. The results obtained in the 200-1000 Hz were used to draw a rough estimation of the beginnings of the injections in order to determine the parts of the records on which the location signal processing can be carried out.

    The CTH actinide separation process has been tested by treating 16 l of 10 year old waste solution from PUREX reprocessing of metallic fuel. It was in general found to operate well and, in some respects, slightly better than design specifications. The extraction process removed more than 99.995% of initial alpha activity. After the sorption steps 5 Bq/l β-activity remained in solution. The modified reversed TALSPEAK process used to separate Am and Cm from the lanthanides gave an Am-Cm product with less than 0.7% of the lanthanides and vice versa. This result can probably be somewhat improved by continuous addition of lactic acid and closer pH control. (orig.)

  16. Non-local energy density functionals: models plus some exact general results

    2001-02-01

    Holas and March (Phys. Rev. A51, 2040, 1995) gave a formally exact expression for the force - δV xc (r-tilde)/δr-tilde associated with the exchange-correlation potential V xc (r-tilde) of density functional theory. This forged a precise link between first- and second-order density matrices and V xc (r-tilde). Here models are presented in which these low-order matrices can be related to the ground-state electron density. This allows non-local energy density functionals to be constructed within the framework of such models. Finally, results emerging from these models have led to the derivation of some exact 'nuclear cusp' relations for exchange and correlation energy densities in molecules, clusters and condensed phases.

    The use of wind energy to produce electricity through wind turbines has spread world-wide. The quantity of electricity produced is affected by numerous factors such as wind speed and direction and turbine design; the aim of this paper is to assess the influence of different blades on the performance of a turbine. This study was performed on a turbine in which the blades have a rotating movement, each around its own axis and around the turbine's axis. Unsteady simulations were carried out with several blade stagger angles and one wind speed and 2 different blade geometries were used for 4 rotational speeds. Results showed that the studied turbine gave better performance than vertical axis wind turbines and that blade sketch, blade speed ratios, and blade stagger angle were important influences on the performance. This study showed that this kind of turbine has the potential to achieve good performance but that further work needs to be done.

    The effect of radioactive labelling (H/sup 3/-thymidine) on the infusorian division is studied. The presented results show that introduction of labelled compounds results in accelerating infusorian cell division v. Thorough investigation of labelled compound effect with low activity on the parameters of cell division and the search of methods to eliminate distortions able to appear in autoradiographic experiments is expedient.

  9. The Ulysses fast latitude scans: COSPIN/KET results

    Full Text Available Ulysses, launched in October 1990, began its second out-of-ecliptic orbit in December 1997, and its second fast latitude scan in September 2000. In contrast to the first fast latitude scan in 1994/1995, during the second fast latitude scan solar activity was close to maximum. The solar magnetic field reversed its polarity around July 2000. While the first latitude scan mainly gave a snapshot of the spatial distribution of galactic cosmic rays, the second one is dominated by temporal variations. Solar particle increases are observed at all heliographic latitudes, including events that produce >250 MeV protons and 50 MeV electrons. Using observations from the University of Chicago’s instrument on board IMP8 at Earth, we find that most solar particle events are observed at both high and low latitudes, indicating either acceleration of these particles over a broad latitude range or an efficient latitudinal transport. The latter is supported by "quiet time" variations in the MeV electron background, if interpreted as Jovian electrons. No latitudinal gradient was found for >106 MeV galactic cosmic ray protons, during the solar maximum fast latitude scan. The electron to proton ratio remains constant and has practically the same value as in the previous solar maximum. Both results indicate that drift is of minor importance. It was expected that, with the reversal of the solar magnetic field and in the declining phase of the solar cycle, this ratio should increase. This was, however, not observed, probably because the transition to the new magnetic cycle was not completely terminated within the heliosphere, as indicated by the Ulysses magnetic field and solar wind measurements. We argue that the new A<0-solar magnetic modulation epoch will establish itself once both polar coronal holes have developed.Key words.

    The results obtained by 19 participating dosimetry systems are presented in this section. Section 3 of the preceding report, ''Evaluation of the Results of the First IAEA Coordinated Research Program on Intercomparison for Individual Monitoring'', explains the format and conventions used for the graphical presentation. The system number appearing in the upper left hand corner of each page can be used to correlate the dosimeter design information found in Table 2 of the preceding report with the results. However, care should be used in drawing inferences from this correlation, since system performance depends on a number of factors other than detector selection and design characteristics. (orig.)

    Results of a comprehensive study on short-term direct impacts and consumer interruption costs, incurred as a result of power supply interruption, were discussed. The emphasis was on questionnaire development, general responses and the average customer damage function of some selected sectors. The customer damage function was established for each category of customers (agriculture, industry, mining, wholesale, retail merchandising, residential, etc) as well as for different locations. Results showed that the average customer damage function depended mostly on customer category. Size and location were not significant factors. 5 refs., 7 tabs.

    With the aim of determining the irradiation-induced embrittlement of a base metal and a weld metal in a pressure vessel of the nuclear icebreaker Lenin after 18 years operation the specimens cut out of a vessel wall are used to study the chemical composition and to carry out impact tests. From the test results the temperature dependences of fracture energy are built which define the irradiation embrittlement of a low alloy steel. It is noted that the annealing at 475 deg C for 100 h results in complete restoration of impact strength. Based on the results obtained the following conclusions are formulated: a reactor vessel base metal has high resistance to brittle fracture and high radiation resistance; a weld metal possesses rather high radiation resistance but unsatisfactory ductile-brittle transition temperature (∼ 63 deg C); for cladded vessels there is a potential reserve in the form of enhanced radiation resistance of an undercladding layer; in the final stage of operation the coolant temperature is recommended to be kept at the highest possible level [ru

  2. Automated, computer interpreted radioimmunoassay results

    Hill, J.C.; Nagle, C.E.; Dworkin, H.J.; Fink-Bennett, D.; Freitas, J.E.; Wetzel, R.; Sawyer, N.; Ferry, D.; Hershberger, D.

    1984-01-01

    90,000 Radioimmunoassay results have been interpreted and transcribed automatically using software developed for use on a Hewlett Packard Model 1000 mini-computer system with conventional dot matrix printers. The computer program correlates the results of a combination of assays, interprets them and prints a report ready for physician review and signature within minutes of completion of the assay. The authors designed and wrote a computer program to query their patient data base for radioassay laboratory results and to produce a computer generated interpretation of these results using an algorithm that produces normal and abnormal interpretives. Their laboratory assays 50,000 patient samples each year using 28 different radioassays. Of these 85% have been interpreted using our computer program. Allowances are made for drug and patient history and individualized reports are generated with regard to the patients age and sex. Finalization of reports is still subject to change by the nuclear physician at the time of final review. Automated, computerized interpretations have realized cost savings through reduced personnel and personnel time and provided uniformity of the interpretations among the five physicians. Prior to computerization of interpretations, all radioassay results had to be dictated and reviewed for signing by one of the resident or staff physicians. Turn around times for reports prior to the automated computer program generally were two to three days. Whereas, the computerized interpret system allows reports to generally be issued the day assays are completed

  3. Presentation of economic evaluation results.

    2014-05-01

    The first HTA guidelines for Thailand included a chapter outlining a set of guidelines on how best to report the findings of health economic evaluations, based on a review of best practice and existing guidelines on the presentation of economic evaluation results from around the world. In this second edition of HTA guidelines for Thailand, the recommendations build on the first edition by using a case study to illustrate how the guidelines can be applied in a real research context. The guidelines propose that all reporting include ten key elements: defining the scope of the study, selection of comparator(s), defining the type of economic evaluation, measurement of costs, measurement of clinical effects, handling time in economic evaluation studies, handling uncertainty and sensitivity analysis, presentation of the results, discussion of the results, and disclosure of funding and authors conflict of interest.

    This is a summary of some of the many recent results from the CERN and Fermilab colliders, presented for an audience of nuclear, medium-energy, and elementary particle physicists. The topics are jets and QCD at very high energies, precision measurements of electroweak parameters, the remarkably heavy top quark, and new results on the detection of the large flux of B mesons produced at these machines. A summary and some comments on the bright prospects for the future of hadron colliders conclude the talk. 39 refs., 44 figs., 3 tabs

  5. First results from SAGE II

    International Nuclear Information System (INIS)

    Abdurashitov, J.N.; Faizov, E.L.; Gavrin, V.N.

    1994-01-01

    The Russian-American Gallium solar neutrino Experiment (SAGE) began the second phase of operation (SAGE II) in September of 1992. Monthly measurements of the integral flux of solar neutrinos have been made with 55 tonnes of gallium. The K-peak results of the first five runs of SAGE II give a capture rate of 76 -18 +21 (stat) -7 +5 (sys) SNU. combined with the SAGE I result, the capture rate is 74 -12 +13 (stat) -7 +5 (sys) SNU. This represents only 56%--60% of the capture rate predicted by different Standard Solar Models

  6. Impossibility results for distributed computing

    2014-01-01

    To understand the power of distributed systems, it is necessary to understand their inherent limitations: what problems cannot be solved in particular systems, or without sufficient resources (such as time or space). This book presents key techniques for proving such impossibility results and applies them to a variety of different problems in a variety of different system models. Insights gained from these results are highlighted, aspects of a problem that make it difficult are isolated, features of an architecture that make it inadequate for solving certain problems efficiently are identified

  7. Turning Science Results into News

    2006-09-01

    Do you want to get into the New York Times? Aside from writing an angry letter or robbing a bank, getting into the news (with your science result) requires a well-crafted press release. Reaching out to reporters is very different from reaching out to fellow scientists. Scientific significance is not the same as newsworthiness, but many science results can be molded into interesting stories that reporters can relate to their audience. This presentation will present examples of science stories that made it big and some that flopped. We will also examine what makes a story attractive to newspaper and magazine editors.

  8. Communicating Performance Assessments Results - 13609

    International Nuclear Information System (INIS)

    Layton, Mark

    2013-01-01

    The F-Area Tank Farms (FTF) and H-Area Tank Farm (HTF) are owned by the U.S. Department of Energy (DOE) and operated by Savannah River Remediation LLC (SRR), Liquid Waste Operations contractor at DOE's Savannah River Site (SRS). The FTF and HTF are active radioactive waste storage and treatment facilities consisting of 51 carbon steel waste tanks and ancillary equipment such as transfer lines, evaporators and pump tanks. Performance Assessments (PAs) for each Tank Farm have been prepared to support the eventual closure of the underground radioactive waste tanks and ancillary equipment. PAs provide the technical bases and results to be used in subsequent documents to demonstrate compliance with the pertinent requirements for final closure of the Tank Farms. The Tank Farms are subject to a number of regulatory requirements. The State regulates Tank Farm operations through an industrial waste water permit and through a Federal Facility Agreement approved by the State, DOE and the Environmental Protection Agency (EPA). Closure documentation will include State-approved Tank Farm Closure Plans and tank-specific closure modules utilizing information from the PAs. For this reason, the State of South Carolina and the EPA must be involved in the performance assessment review process. The residual material remaining after tank cleaning is also subject to reclassification prior to closure via a waste determination pursuant to Section 3116 of the Ronald W. Reagan National Defense Authorization Act of Fiscal Year 2005. PAs are performance-based, risk-informed analyses of the fate and transport of FTF and HTF residual wastes following final closure of the Tank Farms. Since the PAs serve as the primary risk assessment tools in evaluating readiness for closure, it is vital that PA conclusions be communicated effectively. In the course of developing the FTF and HTF PAs, several lessons learned have emerged regarding communicating PA results. When communicating PA results it is

  9. Experimental results surprise quantum theory

    International Nuclear Information System (INIS)

    White, C.

    1986-01-01

    Interest in results from Darmstadt that positron-electron pairs are created in nuclei with high atomic numbers (in the Z range from 180-188) lies in the occurrence of a quantized positron kinetic energy peak at 300. The results lend substance to the contention of Erich Bagge that the traditionally accepted symmetries in positron-electron emission do not exist and, therefore, there is no need to posit the existence of the neutrino. The search is on for the decay of a previously unknown boson to account for the findings, which also points to the need for a major revision in quantum theory. 1 figure

    Baker, John G.

    2011-01-01

    For several years numerical simulations have been revealing the details of general relativity's predictions for the dynamical interactions of merging black holes. I will review what has been learned of the rich phenomenology of these mergers and the resulting gravitational wave signatures. These wave forms provide a potentially observable record of the powerful astronomical events, a central target of gravitational wave astronomy. Asymmetric radiation can produce a thrust on the system which may accelerate the single black hole resulting from the merger to high relative velocity.

  9. Stability of Global Geodetic Results

    Science.gov (United States)

    Herring, T.

    The precision of global geodetic techniques has reached unprecedented levels. Sys- tems capable of millimeter level horizontal and several millimeter vertical precisions are now deployed. The Global Positioning System (GPS) has the most deployed continuously-operating receivers with several hundred providing data through the in- ternet for analysis. However, the satellite system used with GPS evolves with time as new generations of GPS satellites are launched. During the 1990's, the constellation evolved from Block I to Block II and IIA with the most recent generation being Block IIR. There are considerable differences in the size and antenna configurations in the different generations of satellites. The antenna configuration specifically could cause systematic changes in the terrestrial reference system. Results from the ITRF2000 combinations suggest that there are significant time variations in the scale of GPS system possibly due to phase center variations in GPS transmission antennas. These variations could result in height changes of up to 3 mm/yr. We will investigate the stability of the GPS system through combination of GPS results with results from VLBI and SLR. All components of the transformation between the systems, rotation, translation and scale will be investigated.

    International Nuclear Information System (INIS)

    Baril, L.; Carmel, R.

    1978-01-01

    Folate assays by use of radiolabeled folate provide obvious practical advantages over the standard microbiological assay, but remain incompletely tested. We therefore compared results for 415 sera with a kit involving 3 H-labeled folate and the Lactobacillus casei microbiological method. We examined the patients' data when there were discrepancies between the two methods. Although the correlation overall was satisfactory, results were discrepant in 25% of cases. In 74% of the latter, the radioassay result appeared to be the correct one, primarily because L. casei results were suppressed by antibiotics being taken by the patient. The radioassay occasionally gave falsely high values for patients with liver disease and falsely low ones for patients who had received isotopes for scanning purposes. Several assay kits that make use of 125 I- or 75 Se-labeled folate were also tested. Although these results correlated with the results of 3 H-labeled folate assay, various problems appeared, including the possible need for serum-supernate control tubes in one kit. Answers to these and other questions and careful clinical correlation of results are needed for any folate radioassays before their adoption for routine clinical use

    1980-07-01

    Behavior of elementary particles at very high energies and new phenomena observed are discussed in the light of results obtained by cosmic ray studies. Methods of determining hadron-nucleus inelastic cross-sections are described. Proton energy spectra are studied at 2000-50,000 GeV and the hadron-proton total cross section is deduced. Measurement of the cross-section by measurement of the intensity of transition radiation is described. The instrumental effects and the corrections effected are mentioned. The results obtained by different groups of investigators are compared. Observations on the scaling violation at high energies are reported. New particles or phenomena observed include: (i) the long flying component (ii) centauro events, (iii) delayed particles (iv) high energy cascades in underground experiments and (v) charm hadron production in hadron collisions. New experiments being planned for further research are mentioned.

    ALICE is the LHC experiment dedicated to the study of heavy-ion collisions. The main purpose of ALICE is to investigate the properties of a state of deconfined nuclear matter, the Quark Gluon Plasma. Heavy flavour measurements will play a crucial role in this investigation. The physics programme of ALICE has started by studying proton-proton collisions at unprecedented high energies. We will present the first results on open heavy flavour and quarkonia in proton-proton collisions at √s = 7 TeV measured by the ALICE experiment at both mid- and forward-rapidities. We will conclude with the prospects for heavy flavour and quarkonium measurements in both proton-proton and nucleus-nucleus collisions.

    Conservatism of current safety analysis was assessed by comparing the predicted result with cylindrical core test facility (CCTF) test result performed at Japan Atomic Energy Research Institute. WREM code was selected for the assessment. The overall conservatism of the WREM code on the peak clad temperature prediction was confirmed against CCTF evaluation model (EM) test which simulated the typical initial and boundary conditions in the safety evaluation analysis. WREM code predicted the reasonable core boundary conditions and the conservatism of the code came mainly from core calculation. The conservatism of the WREM code against CCTF data could be attributed to the following three points: (1) no horizontal mixing assumption between subchannels at each elevation; (2) no modeling on heat transfer enhancement caused by the radial core power profile; and (3) conservative heat transfer correlations in the code

    The F-Area Tank Farms (FTF) and H-Area Tank Farm (HTF) are owned by the U.S. Department of Energy (DOE) and operated by Savannah River Remediation LLC (SRR), Liquid Waste Operations contractor at DOE's Savannah River Site (SRS). The FTF and HTF are active radioactive waste storage and treatment facilities consisting of 51 carbon steel waste tanks and ancillary equipment such as transfer lines, evaporators and pump tanks. Performance Assessments (PAs) for each Tank Farm have been prepared to support the eventual closure of the underground radioactive waste tanks and ancillary equipment. PAs provide the technical bases and results to be used in subsequent documents to demonstrate compliance with the pertinent requirements for final closure of the Tank Farms. The Tank Farms are subject to a number of regulatory requirements. The State regulates Tank Farm operations through an industrial waste water permit and through a Federal Facility Agreement approved by the State, DOE and the Environmental Protection Agency (EPA). Closure documentation will include State-approved Tank Farm Closure Plans and tank-specific closure modules utilizing information from the PAs. For this reason, the State of South Carolina and the EPA must be involved in the performance assessment review process. The residual material remaining after tank cleaning is also subject to reclassification prior to closure via a waste determination pursuant to Section 3116 of the Ronald W. Reagan National Defense Authorization Act of Fiscal Year 2005. PAs are performance-based, risk-informed analyses of the fate and transport of FTF and HTF residual wastes following final closure of the Tank Farms. Since the PAs serve as the primary risk assessment tools in evaluating readiness for closure, it is vital that PA conclusions be communicated effectively. In the course of developing the FTF and HTF PAs, several lessons learned have emerged regarding communicating PA results. When communicating PA results it is

    The PREVAIL electron optics subsystem developed by IBM has been installed at Nikon's facility in Kumagaya, Japan, for integration into the Nikon commercial EPL stepper. The cornerstone of the electron optics design is the Curvilinear Variable Axis Lens (CVAL) technique originally demonstrated with a proof of concept system. This paper presents the latest experimental results obtained with the electron optical subsystem at Nikon's facility. The results include micrographs illustrating proper CVAL operation through the spatial resolution achieved over the entire optical field of view. They also include data on the most critical issue of the EPL exposure approach: subfield stitching. The methodology of distortion correction will be described and both micrographs and metrology data of stitched subfields will be presented. This paper represents a progress report of the IBM/Nikon alliance activity on EPL.

    INSPIRE-00008500

    2015-04-10

    We present recent measurements of multijet correlations using forward and low-$p_{\\mathrm{T}}$ jets performed by the CMS collaboration at the LHC collider. In pp collisions at $\\sqrt{s} = 7$ TeV, azimuthal correlations in dijets separated in rapidity by up to 9.4 units were measured. The results are compared to BFKL- and DGLAP-based Monte Carlo generator and analytic predictions. In pp collisions at $\\sqrt{s} = 8$ TeV, cross sections for jets with $p_{\\mathrm{T}}$ > 21 GeV and |y| 1 GeV (minijets) are presented. The minijet results are sensitive to the bound imposed by the total inelastic cross section, and are compared to various models for taming the growth of the $2 \\rightarrow 2$ cross section at low $p_{\\mathrm{T}}$.

    High-energy astrophysics space missions have pioneered and demonstrated the power of legacy data sets for generating new discoveries, especially when analysed in ways original researchers could not have anticipated. The only way to ensure that the data of present observatories can be effectively used in the future is to allow users to perform on-the-fly data analysis to produce straightforwardly scientific results for any sky position, time and energy intervals without requiring mission specific software or detailed instrumental knowledge. Providing a straightforward interface to complex data and data analysis makes the data and the process of generating science results available to the public and higher education and promotes the visibility of the investment in science to the society. This is a fundamental step to transmit the values of science and to evolve towards a knowledge society.

  19. Analytical results for Abelian projection

    Ogilivie, Michael C.

    1999-01-01

    Analytic methods for Abelian projection are developed, and a number of results related to string tension measurements are obtained. It is proven that even without gauge fixing, Abelian projection yields string tensions of the underlying non-Abelian theory. Strong arguments are given for similar results in the case where gauge fixing is employed. The subgroup used for projection need only contain the center of the gauge group, and need not be Abelian. While gauge fixing is shown to be in principle unnecessary for the success of Abelian projection, it is computationally advantageous for the same reasons that improved operators, e.g., the use of fat links, are advantageous in Wilson loop measurements

  20. Marshland study brings fruitful results

    1978-03-01

    There are approximately 110,000 square kilometers of marshland in China containing peat and other valuable resources. The results of a marshland study have been presented as a chapter in a book titled Physical Geography of China. In 1970, the Kirin Normal University established an experimental plant for the utilization of peat. Four kinds of peat fertilizers produced by this plant have been used with good results at 20 communes in Kirin Province. Four kinds of construction materials (peat board, peat tiles, peat insulation bricks and peat insulation tubes) were also successfully made. A certain type of peat can be used as fuel to heat malt in the process of whiskey making. New applications of peat have been found in medicine, water purification, and in the manufacturing of electrodes for condensers.

    We present results from a novel Cherenkov imaging detector called the Focusing DIRC (FDIRC). This detector was designed as a prototype of the particle identification system for the SuperB experiment, and comprises 1/12 of the SuperB barrel azimuthal coverage with partial electronics implementation. The prototype was tested in the SLAC Cosmic Ray Telescope (CRT) which provides 3-D muon tracking with an angular resolution of ∼1.5 mrad, track position resolution of 5–6 mm, start time resolution of 70 ps, and a muon low-energy cutoff of ∼2 GeV provided by an iron range stack. The quartz focusing photon camera couples to a full-size BaBar DIRC bar box and is read out by 12 Hamamatsu H8500 MaPMTs providing 768 pixels. We used IRS2 waveform digitizing electronics to read out the MaPMTs. We present several results from our on-going development activities that demonstrate that the new optics design works very well, including: (a) single photon Cherenkov angle resolutions with and without chromatic corrections, (b) S/N ratio between the Cherenkov peak and background, which consists primarily of ambiguities in possible photon paths to a given pixel, (c) dTOP=TOP{sub measured}–TOP{sub expected} resolutions, and (d) performance of the detector in the presence of high-rate backgrounds. We also describe data analysis methods and point out limits of the present performance. - Highlights: • We present results from a novel Cherenkov imaging detector called the Focusing DIRC (FDIRC). • The prototype was tested in the SLAC Cosmic Ray Telescope (CRT) which provides 3-D muon tracking. • We present several results from our on-going development activities that demonstrate that new optics design works very well. • We describe data analysis methods and point out limits of the present performance.

    Tremendous progress has been made in mapping out the spectrum of hadrons over the past decade with plans to make further advances in the decade ahead. Baryons and mesons, both expected and unexpected, have been found, the results of precision experiments often with polarized beams, polarized targets and sometimes polarization of the final states. All these hadrons generate poles in the complex energy plane that are consequences of the strong coupling regime of QCD. They reveal how this works.

  14. Audit result and its users

    Shalimova Nataliya S.

    2014-01-01

    Full Text Available The article identifies essence of the “audit result” and “users of audit result” notions and characteristics of the key audit results user. It shows that in order to give a wide characteristic of users it is expedient to unite all objects, which could be used (audit report, fact of refusal to conduct audit and information that is submitted to managers in the process of audit with the term “audit result” and classify it depending on the terms of submission by final and intermediate result. The article offers to define audit results user as a person, persons or category of persons for whom the auditor prepares the audit report and, in cases, envisaged by international standards of the audit and domestic legislative and regulatory acts, provides other additional information concerning audit issues. In order to identify the key audit results user the article distributes all audit tasks into two groups depending on possibilities of identification of users. The article proves that the key user should be identified especially in cases of a mandatory audit and this process should go in interconnection with the mechanism of allocation of a key user of financial reports. It offers to consider external users with direct financial interests, who cannot request economic subjects directly to provide information and who should rely on general financial reports and audit report when receiving significant portion of information they need, as the key user. The article makes proposals on specification of the categorical mechanism in the sphere of audit, which are the basis for audit quality assessment, identification of possibilities and conditions of appearance of the necessary and sufficient trust to the auditor opinion.

    Gaz de France (GDF) presents in a press kit the main results achieved in 1997. The European community has formulated a project of definition of rules concerning the natural gas market. Minima values for annual consumptions have been defined and the consumption and use of natural gas in EC countries is described. The financial results of GDF in 1997 are compared with previous years. Net sales grew by nearly 1 billion french francs to reach 55 billion. Overall sales were down by 4% but the share of natural gas in french energy consumption increased and sales to industrial users went up in particular due to new cogeneration plants installed in 1996. A comparison of gas prices in Europe is given for the years 1985 to 1998. The efforts of GDF to offer increased quality of services concerning in particular safety aspects as checking programs and installation of new safeguard appliances are described. The efforts of GDF to increase the energy market share of natural gas resulted in the development of new products like cogeneration, air conditioning and fuels for automotive needs. (C.B.)

    In 2003, RTE recorded a clear improvement in its financial results, and continued its debt reduction programme. The financial year 2003 was marked by a clear improvement in RTE's financial performance: results exceeded objectives, with turnover growing strongly, net income reached levels almost three times higher than those recorded in 2002, the economic rate of return rose to 7.1%, and debt was reduced by 470 Meuros. These results are explained by the substantial improvement in productivity, which has risen by 5% per year on average over the last three years. Net income has almost tripled due to RTE's improved productivity completed by a significant rise in its turnover and stabilizing operating costs RTE's finances therefore remain healthy, enabling the company to continue its debt reduction programme. Satisfactory economic and financial rates of return. Deadlines facing RTE in 2004: in application of the second European Directive, adopted on 26 June 2003, RTE faces two major deadlines in 2004: - the implementation of the 2. phase in the process of opening up the French electricity market, - its legal independence. On 1 July 2004, the market will be opened up to competition for all professional customers. At that date RTE, like all other electricity transmission system operators (TSOs) in the European Union, should be a legally independent body. The new central role of TSOs in Europe: how are electricity transmission system operators in other EU countries organised?

    The European Space Agency's Planck satellite, dedicated to studying the early Universe and its subsequent evolution, was launched 14~May 2009 and scanned the microwave and submillimetre sky continuously between 12~August 2009 and 23~October 2013. In February~2015, ESA and the Planck Collaboration released the second set of cosmology products based on data from the entire Planck mission, including both temperature and polarization, along with a set of scientific and technical papers and a web-based explanatory supplement. This paper gives an overview of the main characteristics of the data and the data products in the release, as well as the associated cosmological and astrophysical science results and papers. The science products include maps of the cosmic microwave background (CMB), the thermal Sunyaev-Zeldovich effect, and diffuse foregrounds in temperature and polarization, catalogues of compact Galactic and extragalactic sources (including separate catalogues of Sunyaev-Zeldovich clusters and Galactic col...

  3. Influence of fractionation of dose on 3 year results of X-ray therapy of skin cancer

    International Nuclear Information System (INIS)

    Szymczyk, W.; Radziszewska, J.; Cyplik, I.; Glinska, H.

    1985-01-01

    Three-year results of X-ray therapy of skin cancer in 345 patients are presented. The dependence of results on the size of irradiated field and the method of dose fractionation is analysed. The clinical usefulness of a cumulative radiation effect (CRE) is evaluated. 96.5% of three-year cures were obtained. Recurrences amounted to 1.6% and necroses to 1.9% of treated lesions. It has been shown that treatment of small fields with 8-fractions gave equally positive results as with 15-fractions whereas in the treatment of large lesions the selection of CRE value, a number of fractions and dose should let the value of CRE minimally exceeds the level of tolerance of healthy tissues. The regard to CRE value in the treatment of large lesions or the introduction of additional dosimetric acts seems to be useful. 10 refs., 1 fig., 5 tabs. (author)

  4. Results of the Schooner excavation experiment

    Energy Technology Data Exchange (ETDEWEB)

    Tewes, Howard A [Lawrence Radiation Laboratory, University of California, Livermore, CA (United States)

    1970-05-01

    Project Schooner, a nuclear detonation in interlayered hard and soft, partially saturated volcanic rock, was executed as a part of the Plowshare Program for development of nuclear excavation techniques. The primary objectives of this experiment were: (a) to obtain experimental data on crater development and size in a new medium to further verify existing rock mechanics computer codes and calculational techniques; and (b) to determine the fractional release of radioactivity from a nuclear detonation in wet rock. As was noted in the case of the Sedan experiment, appreciable (though relatively small) amounts of radioactivity were released to the environment from this detonation in hard, partially saturated rock. Although the thermo-nuclear explosive used in this experiment gave a yield of approximately 31 kilotons, only the equivalent of the fission products from about 370 tons of fission were distributed in both fallout and cloud. Data which have been reduced to date indicate that this released radioactivity underwent only a moderate amount of chemical fractionation, being much more similar in this respect to Sedan than to Danny Boy.

  6. Overview of the FTU results

    1999-01-01

    An overview of the Frascati Tokamak Upgrade results during the period 1996-1998 is presented. Most of the activity has been devoted to the investigation of the electron heat transport with flat/nonmonotonic safety factor profiles. Up to 14 keV of electron temperature have been obtained using electron cyclotron resonance heating (ECRH) on the current ramp. The transport analysis shows a very low electron heat transport in the region with flat/nonmonotonic safety factor profile. The electron thermal conductivity is strongly dependent on the MHD activity and it drops to values of the order 0.1 m 2 /s in the absence of MHD fluctuations. Upon varying the resonance position in steady state conditions the effect of the ECRH on the sawtooth stabilization has been also investigated. Lower hybrid current drive studies have been performed in order to investigate the dependence of the current drive efficiency with density. Previous results of the Alcator C tokamak pointed out that at high density rather low efficiency values were obtained. The investigation carried out on FTU shows that such a result can be explained as due to the electron temperature dependence of the current drive efficiency. No degradation of the current drive efficiency is indeed observed on FTU even at density values of the order 10 20 m -3 . Ion Bernstein wave (IBW) heating studies have been also carried out in order to check the behaviour of wave-plasma coupling which is found in agreement with linear theory. Finally, impurity transport studies have been carried out. It has been possible to have a direct measurement of the flux of Mo33 which turns out to be in agreement with the expectation of quasilinear theory. (author)

    Lyon, Richard G.; Clampin, Mark; Woodruff, Robert A.; Vasudevan, Gopal; Thompson, Patrick; Petrone, Peter; Madison, Timothy; Rizzo, Maxime; Melnick, Gary; Tolls, Volker

    2009-08-01

    We report on our recent laboratory results with the NASA/Goddard Space Flight Center (GSFC) Visible Nulling Coronagraph (VNC) testbed. We have experimentally achieved focal plane contrasts of 1 x 108 and approaching 109 at inner working angles of 2 * wavelength/D and 4 * wavelength/D respectively where D is the aperture diameter. The result was obtained using a broadband source with a narrowband spectral filter of width 10 nm centered on 630 nm. To date this is the deepest nulling result with a visible nulling coronagraph yet obtained. Developed also is a Null Control Breadboard (NCB) to assess and quantify MEMS based segmented deformable mirror technology and develop and assess closed-loop null sensing and control algorithm performance from both the pupil and focal planes. We have demonstrated closed-loop control at 27 Hz in the laboratory environment. Efforts are underway to first bring the contrast to > 109 necessary for the direct detection and characterization of jovian (Jupiter-like) and then to > 1010 necessary for terrestrial (Earth-like) exosolar planets. Short term advancements are expected to both broaden the spectral passband from 10 nm to 100 nm and to increase both the long-term stability to > 2 hours and the extent of the null out to a ~ 10 * wavelength / D via the use of MEMS based segmented deformable mirror technology, a coherent fiber bundle, achromatic phase shifters, all in a vacuum chamber at the GSFC VNC facility. Additionally an extreme stability textbook sized compact VNC is under development.

  8. Overview of recent ALICE results

    Gunji, Taku

    2016-12-15

    The ALICE experiment explores the properties of strongly interacting QCD matter at extremely high temperatures created in Pb-Pb collisions at LHC and provides further insight into small-system physics in (high-multiplicity) pp and p-Pb collisions. The ALICE collaboration presented 27 parallel talks, 50 posters, and 1 flash talk at Quark Matter 2015 and covered various topics including collective dynamics, correlations and fluctuations, heavy flavors, quarkonia, jets and high p{sub T} hadrons, electromagnetic probes, small system physics, and the upgrade program. This paper highlights some of the selected results.

  9. Recent QCD results from ATLAS

    CERN Document Server

    Meyer, C; The ATLAS collaboration

    2014-01-01

    The ATLAS collaboration has performed studies of a wide range of QCD phenomena, from soft particle to hard photon and jet production. Recent soft-QCD measurements include studies of underlying event and vector meson production. Differential measurements of inclusive and dijet production provide stringent tests of high-order QCD predictions and provide input for determination of parton density functions. Measurements of isolated inclusive and di-photons cross sections for high transverse momentum photons test theoretical predictions of perturbative QCD and constrain parton density functions. An overview of these results is given.

  10. The OPERA Experiment. Latest results

    Hollnagel, Annika [Universitaet Hamburg, Institut fuer Experimentalphysik (Germany); Collaboration: OPERA-Hamburg-Collaboration

    2015-07-01

    The long-baseline neutrino oscillation experiment OPERA has been designed for the direct observation of ν{sub τ} appearance in the CNGS ν{sub μ} beam. The OPERA detector is located at the LNGS underground laboratory, with a distance of 730 km from the neutrino source at CERN. It is a hybrid detector, combining the micrometric precision of emulsion cloud chambers with electronic detector elements for online readout. While CNGS beam data taking lasted from 2008 to 2012, the neutrino oscillation analysis is still ongoing. Updated results with increased statistics are presented, including the recent observation of ν{sub τ} appearance.

  11. RSG Deployment Case Testing Results

    Owsley, Stanley L.; Dodson, Michael G.; Hatchell, Brian K.; Seim, Thomas A.; Alexander, David L.; Hawthorne, Woodrow T.

    2005-09-01

    The RSG deployment case design is centered on taking the RSG system and producing a transport case that houses the RSG in a safe and controlled manner for transport. The transport case was driven by two conflicting constraints, first that the case be as light as possible, and second that it meet a stringent list of Military Specified requirements. The design team worked to extract every bit of weight from the design while striving to meet the rigorous Mil-Spec constraints. In the end compromises were made primarily on the specification side to control the overall weight of the transport case. This report outlines the case testing results.

    Bohnhoff-Hlavacek, Gail

    1993-01-01

    The Long Duration Exposure Facility (LDEF) carried 57 experiments and 10,000 specimens for some 200 LDEF experiment investigators. The external surface of LDEF had a large variety of materials exposed to the space environment which were tested preflight, during flight, and post flight. Thermal blankets, optical materials, thermal control paints, aluminum, and composites are among the materials flown. The investigations have produced an abundance of analysis results. One of the responsibilities of the Boeing Support Contract, Materials and Systems Special Investigation Group, is to collate and compile that information into an organized fashion. The databases developed at Boeing to accomplish this task is described.

  14. Results of nuclear fusion development

    International Nuclear Information System (INIS)

    Yamamoto, Kenzo

    1975-01-01

    Compared with the nuclear fission research which followed that in advanced countries, Japan has treaded on its own track in nuclear fusion development; in the former, she had been far behind other leading countries. Characteristic of the efforts in Japan is the collaboration with educational institutions. Works are now carried out mainly in Tokamak plasma confinement, though other means being studied simultaneously. The nation's fusion research program is the realization of a fusion reactor at the turn of the present century, based on the world-level results attained with Tokamak. Past developments in the nuclear fusion research, the current status, and aspects for the future are discribed. (Mori, K.)

    International Nuclear Information System (INIS)

    Skimko, M.A.; Stacy, W.D.; McCormick, J.A.

    1992-01-01

    This paper reports that recent testing of diaphragm-defined, Stirling-cycle machines and components has demonstrated cooling performance potential, validated the design code, and confirmed several critical operating characteristics. A breadboard cryocooler was rebuilt and tested from cryogenic to near-ambient cold end temperatures. There was a significant increase in capacity at cryogenic temperatures and the performance results compared will with code predictions at all temperatures. Further testing on a breadboard diaphragm compressor validated the calculated requirement for a minimum axial clearance between diaphragms and mating heads

  16. Recent results for Mark III

    International Nuclear Information System (INIS)

    Brient, J.C.

    1987-12-01

    This paper presents recent results from the Mark III detector at SPEAR, in the open charm sector. The first topic discussed is the reanalysis of the direct measurement of the D hadronic branching fractions, where a detailed study has been made of the Cabibbo suppressed and multi-π 0 's D decays backgrounds in the double tag sample. Next, the Dalitz plot analysis of the D decays to Kππ is presented, leading to the relative fractions of three-body versus pseudoscalarvector decays. 7 refs., 5 figs

    1981-01-01

    The Los Alamos free-electron laser (FEL) amplifier experiment was designed to demonstrate high efficiency for transfer of energy from an electron beam to a light beam in the magnetic field of a tapered wiggler. Initial results indicate an energy transfer consistent with theory. Distinct groups of decelerated electrons as well as accelerated electrons are clearly present in the energy spectrum of electrons emerging from the wiggler when the laser light is present. The observed energy decrease for the electrons captured in the decelerating bucket is approx. 6% and the average decrease of the entire energy distribution is approx. 2% for the conditions of these initial measurements

    Glasman, Claudia; The ATLAS collaboration

    2017-01-01

    The production of prompt isolated photons at hadron colliders provides a stringent test of perturbative QCD and can be used to probe the gluon density function of the proton. The ATLAS collaboration has performed precise measurements of the inclusive production o f isolated prompt photons at a center-of-mass energy of 13 TeV, differential in both rap idity and the photon transverse momentum. In addition, the integrated and differential c ross sections for isolated photon pair production 8 TeV have been measured. The results are compared with state-of-the-art theory predictions at NLO in QCD and with predictions of several MC generators.

    Casasent, David; Jackson, James; Vaerewyck, Gerard

    1987-01-01

    A Space Integrating (SI) Optical Linear Algebra Processor (OLAP) is described and laboratory results on its performance in several practical engineering problems are presented. The applications include its use in the solution of a nonlinear matrix equation for optimal control and a parabolic Partial Differential Equation (PDE), the transient diffusion equation with two spatial variables. Frequency-multiplexed, analog and high accuracy non-base-two data encoding are used and discussed. A multi-processor OLAP architecture is described and partitioning and data flow issues are addressed.

    International Nuclear Information System (INIS)

    Podobrin, O.

    1991-10-01

    In this talk result from CELLO on multiparticle production in e + e - annihilation are presented. The three-dimensional distribution of charged particles, and its one- and two-dimensional projections, are extensively studied through the bin-size dependence of their factorial moments. The data are found to have an excellent description by standard Monte Carlo models. This implies an explanation of the observed intermittency behaviour in terms of known physics. The study is extended by an analysis of two-particle rapidity correlations. (orig.)

    2000-01-01

    The NOMAD experiment has sought nu /sub mu / implies/implied by nu /sub tau / oscillations by looking for the emergence of tau /sup -/ in events from the CERN SPS neutrino beam. With some improvements in the techniques of analysis in relation to the results published previously and with the inclusion of data from the 1998 run, no evidence for the oscillations has been found, which results in an updated limit on the oscillation probability [P( nu /sub mu / to nu /sub tau /)<0.5* 10/sup -3/ at a 90% C.L.]. The corresponding limit on the oscillation mixing angle is given by sin/sup 2/2 theta /sub mu tau /<1.0*10/sup -3/ for large Delta m/sup 2/. By using a 1% contamination of nu /sub e/ in the neutrino beam, we can also rule out nu /sub e/ implies/implied by nu /sub tau / oscillations and constrain the probability of the relevant transition as P( nu /sub 3/ to nu /sub tau /)<3*10/sup -2/ at a 90% C.L. (sin/sup 2/2Q/sub e tau /<6*10/sup -2/ at large Delta m/sup 2/). (10 refs).

  5. Unfavourable results following reduction mammoplasty

    Full Text Available Breast reduction is a common cosmetic surgical procedure. It aims not only at bringing down the size of the breast proportionate to the build of the individual, but also to overcome the discomfort caused by massive, ill-shaped and hanging breasts. The operative procedure has evolved from mere reduction of breast mass to enhanced aesthetic appeal with a minimum of scar load. The selection of technique needs to be individualised. Bilateral breast reduction is done most often. Haematoma, seroma, fat necrosis, skin loss, nipple loss and unsightly, painful scars can be the complications of any procedure on the breast. These may result from errors in judgement, wrong surgical plan and imprecise execution of the plan. Though a surfeit of studies are available on breast reduction, very few dwell upon its complications. The following article is a distillation of three decades of experience of the senior author (L.S. in reduction mammoplasty. An effort is made to understand the reasons for unfavourable results. To conclude, most complications can be overcome with proper selection of procedure for the given patient and with gentle tissue handling.

    We developed a method to make GEM foils with a spherical geometry. Tests of this procedure and with the resulting spherical GEMs are presented. Together with a spherical drift electrode, a spherical conversion gap can be formed. This eliminates the parallax error for detection of x-rays, neutrons or UV photons when a gaseous converter is used. This parallax error limits the spatial resolution at wide scattering angles. Besides spherical GEMs, we have developed curved spacers to maintain accurate spacing, and a conical field cage to prevent edge distortion of the radial drift field up to the limit of the angular acceptance of the detector. With these components first tests are done in a setup with a spherical entrance window but a planar readout structure; results will be presented and discussed. A flat readout structure poses difficulties, however. Therefore we will show advanced plans to make a prototype of an entirely spherical double-GEM detector, including a spherical 2D readout structure. This detector w...

    To describe a case of cervical flexion myelopathy resulting from a drug overdose. A 56-year-old male presented to the emergency department unable to move his extremities following drug overdose. Neurological examination revealed him to be at C6 ASIA A spinal cord injury. The CT of his cervical spine revealed no fracture; however, an MRI revealed cord edema extending from C3 to C6 as well as posterior paraspinal signal abnormalities suggestive of ligamentous injury. The patient underwent a posterior cervical laminectomy and fusion from C3 to C7. Neurologically he regained 3/5 bilateral tricep function and 2/5 grip; otherwise, he remained at ASIA A spinal cord injury at 6 months. Our patient suffered a spinal cord injury likely due to existing cervical stenosis, and in addition to an overdose of sedating medications, he likely sat in flexed neck position for prolonged period of time with the inability to modify his position. This likely resulted in cervical spine vascular and/or neurological compromise producing an irreversible spinal cord injury. Spinal cord injury is a rare finding in patients presenting with drug overdose. The lack of physical exam findings suggestive of trauma may delay prompt diagnosis and treatment, and thus clinicians must have a high index of suspicion when evaluating patients in this setting.

  8. New Results on Cepheid Masses

    Masses for Cepheid variable stars can be measured by combining the orbital velocity amplitude for the Cepheid (from a ground-based orbit) with the orbital velocity amplitude of a hot main sequence companion (observed in the ultraviolet from satellites such as IUE and HST) and the mass of the companion (inferred from from the ultraviolet energy distribution). Observations of 5 binary systems are now completed or in progress with the Goddard High Resolution Spectrograph on the Hubble Space Telescope. Recently completed observations of U Aql lead to a mass of 5.1 +/- 1.1 Msun . We will discuss the results for S Mus, V350 Sgr, U Aql, and Y Car, and the constraints they place on stellar evolution calculations. As would be expected, some of the B companions have high rotational velocities, decreasing the accuracy with which their orbital velocities can be measured. The preliminary conclusion from the 4 HST targets and SU Cyg (mass from IUE observations) is that a weighted mean indicates no convective overshoot but the mode (which reflects the HST results better) agrees with the modest overshoot used in the Geneva evolutionary calculations. Financial Support was provided by a NASA grant GO-4541-01 to EB--V and GO-4541.02 to KGC, a grant from the Natural Sciences and Engineering Council, Canada to NRE, from the AXAF Science Center NASA Contract NAS8-39073.

  9. TMX-U experimental results

    Simonen, T.C.; Allen, S.L.; Casper, T.A.

    1983-01-01

    This paper describes results from the Tandem Mirror Experiment-Upgrade (TMX-U). Mirror-confined electrons with 30 to 70 keV mean energy densities of 0.5 to 2.0 x 10 12 cm -3 and average betas of 3 to 5% are produced using electron-cyclotron resonant heating (ECRH). These results are consistent with an electron Fokker-Planck code. Improved ion-cyclotron microstability is observed using neutral beam injection at 47 0 to the magnetic axis, rather than at 90 0 as in the previous experiment, TMX. Strong end plugging has been produced using a combination of ECRH gyrotrons with sloshing-ion beam injection. In these low-density central cell experiments (3 x 10 11 cm -3 ) the axial losses (tau/sub parallel/ = 20 to 80 ms) are smaller than the nonambipolar radial losses (tau/sub perpendicular/ = 4 to 8 ms). Plugging has been achieved with a central cell density double that of the end plugs. Although no direct measurements are yet available to determine if a thermal barrier potential dip is generated, these experiments support many theoretical features of the thermal barrier concept

    The appropriate way to verify the accuracy of the results of dose reported by the laboratories that offer lend personal dosimetry service is in the periodic participation of round of intercomparison dosimetry, undertaken by laboratories whose standards are trace (Secondary Laboratory). The Laboratory of External Personal Dosimetry of the CNEA-PY has participated in three rounds of intercomparison. The first two were organized in the framework of the Model Project RLA/9/030 RADIOLOGICAL WASTE SECURITY, and the irradiations were carried out in the Laboratory of Regional Calibration of the Center of Nuclear Technology Development, Belo Horizonte-Brazil (1998) and in the National Laboratory of Metrology of the ionizing radiations of the Institute of Radioprotection and Dosimetry, Rio de Janeiro-Brazil (1999). The third was organized by the IAEA and the irradiations were made in the Physikalisch-Technische Bundesanstalt PTB, Braunschweig - Federal Republic of Germany (1999-2000) [es

    Recent results regarding heating, confinement, current drive and profile modifications, heat and particle exhaust are reported. Improved core confinement is obtained after pellet injection (PEP) or Lower Hybrid current drive (LHEP) and may be linked with small - or reversed - central magnetic shear. Conversely, by increasing the magnetic shear in the gradient region, both LHCD and fast wave electron heating (FWEH) have produced improved global confinement was carried by the bootstrap current. Fast wave current drive has been observed at the level of 80 kA in a 0.4 MA discharge. In the ergodic divertor configuration, stable radiative layers were obtained with neon injection. At least 80% of a total of 7 MW injected power were radiated without confinement degradation or impurity accumulation. Finally, the heat exhaust capability of the various actively cooled plasma facing components is briefly described. (author) 14 refs.; 13 figs

    High gradient performances of bulk niobium cavities go through a low-temperature baking during one or two days, the temperature parameter is adjusted in a narrow tuning range around 110 or 120deg, C. With such treatment, the intrinsic quality factor Q{sub 0} is improved at high fields. Assuming the oxygen diffusion is involved in this phenomenon, we have developed the 'fast baking' (145deg, C/3h) as an alternative method. Similar results have been achieved with this method compared to standard baking. Consequently, for the first time, a link between oxygen diffusion and high field Q-slope has been demonstrated. Furthermore, this method open the way to a simpler and better baking procedure for the large-scale cavity production due to:*time reduction and *possibility to combine baking and drying during cavity preparation.

    "Cassini At Saturn - Huygens Results" will bring the story of the Cassini-Huygens mission and their joint exploration of the Saturnian system right up to date. Cassini is due to enter orbit around Saturn on the 1 July 2004 and the author will have 8 months of scientific data available for review, including the most spectacular images of Saturn, its rings and satellites ever obtained by a space mission. As the Cassini spacecraft approached its destination in spring 2004, the quality of the images already being returned by the spacecraft clearly demonstrate the spectacular nature of the close-range views that will be obtained. The book will contain a 16-page colour section, comprising a carefully chosen selection of the most stunning images to be released during the spacecraft's initial period of operation. The Huygens craft will be released by Cassini in December 2004 and is due to parachute through the clouds of Saturn's largest moon, Titan, in January 2005.

    Purpose : We tried to evaluate the clinical characteristics, the treatment methods, the results of treatments, and the patterns of failure in ovarian dysgerminoma retrospectively. According to the results we would like to suggest the proper management guideline of stage la ovarian dysgerminoma patients who want to maintain fertility. Methods and Materials : Between 1975 and 1990, 34 patients with ovarian dysgerminoma were treated at the Yonsei University Hospital. The case records of these patients have been reviewed for presenting symptoms, treatment methods, local control, and survival following treatment. Excluded from analysis were five patients with mixed ovarian germ cell tumors and gonadoblastomas (46,XY). Treatment results of the twenty nine patients were analysed by each treatment modality. Twenty one patients were treated with surgery and postoperative adjuvant radiotherapy(group 1). The other eight patients were treated with operation alone (group 2). The median age of twenty-nine patients was 23 years with a range of 8 to 39 years. Presenting symptoms were abdominal mass(20), pelvic discomfort or pain(5) et al. Radiotherapy was performed by 10MV LINAC or Co-60 teletherapy unit. The total radiation dose of the whole abdomen was 20-25 Gy/3 weeks, 1-1.5 Gy/fraction with a boost to the whole pelvis 10-15 Gy / 1-2 weeks1.8-2.0 Gy/fraction. Advanced stage disease (stage II or stage III) patients received prophylactic mediastinal and supraclavicular irradiation to a dose of 16-26 Gy. Median duration of follow-up of living patients was 80 months (range : 13-201 months). Results : All of the twenty one patients of group 1 were alive without disease (100%). Among the eight patients who were not treated with radiotherapy (group 2), six patients developed local recurrence. Four patients referred with recurrent disease were treated with salvage radiotherapy. Three of four patients were salvaged and one patient who had recurrent intra-abdominal disease died of

    The Bigfoot platform was developed on the National Ignition Facility to investigate low convergence, high adiabat, high rhoR hotspot implosions. This platform was designed to be less susceptible to wall motion, LPI and CBET and to be more robust against capsule hydrodynamic instabilities. To date experimental studies have been carried out at two hohlraum scales, a 5.75 and 5.4 mm diameter hohlraum. We will present experimental results from these tuning campaigns including the shape vs. cone fraction, surrogacy comparisons of self-emission from the capsules vs. radiography of the imploding capsule and doped vs. undoped capsules.

    We present a selection of results based on data taken in 1997 with the 302-PMT Antarctic Muon and Neutrino Detector Array-B10 ("AMANDA-B10") array. Atmospheric neutrinos created in the northern hemisphere are observed indirectly through their charged current interactions which produce relativistic, Cherenkov-light-emitting upgoing muons in the South Pole ice cap. The reconstructed angular distribution of these events is in good agreement with expectation and demonstrates the viability of this ice-based device as a neutrino telescope. Studies of nearly vertical upgoing muons limit the available parameter space for WIMP dark matter under the assumption that WIMPS are trapped in the earth's gravitational potential well and annihilate with one another near the earth's center.

  1. Cerebral infarcts resulting from trauma

    Vascular occlusions due to cerebral trauma have always been regarded as great rarities. However, we have found hypo-dense foci of vascular distribution in 3.5% of 3500 CT examinations for trauma during the late phase. Lesions in the vascular territory of the posterior cerebral artery are usually the result of supratentorial pressure rise from epidural and subdural haematomas, leading to compression of the vessels against the edge of the tentorium. Typical infacts in the territory of the medial and anterior cerebral arteries were found only rarely by CT after cerebral trauma. Infarcts at the watersheds between the three vascular territories were found with surprising frequency and small infarcts were found in the basal ganglia. It is assumed that these were due to ischaemic or hypoxic events due to cardiac or pulmonary complications during the initial phase. (orig.) [de

    The Antarctic Muon And Neutrino Detector Array (AMANDA) is a high- energy neutrino telescope based at the geographic south pole. It is a lattice of photomultiplier tubes buried deep in the polar ice, which is used as interaction and detection medium. The primary goal of this detector is the observation of astronomical sources of high-energy neutrinos. This paper shows the latest results of the search for a diffuse flux of extraterrestrial nu /sub mu /s with energies between 10/sup 11/ eV and 10/sup 18/ eV, nu /sub mu /s emitted from point sources and nu /sub mu /s from dark matter annihilation in the Earth and the Sun.

    1983-01-01

    Elements and modules for Radioisotope Thermoelectric Generator have been performance tested since the inception of the RTG program. These test articles seldom resembled flight hardware and often lacked adequate diagnostic instrumentation. Because of this, performance problems were not identified in the early stage of program development. The lack of test data in an unexpected area often hampered the development of a problem solution. A procedure for conducting the MITG Test was developed in an effort to obtain data in a systematic, unambiguous manner. This procedure required the development of extensive data acquisition software and test automation. The development of a facility to implement the test procedure, the facility hardware and software requirements, and the results of the MITG testing are the subject of this paper

    The Cosmic Ray Energetics And Mass (CREAM) balloon-borne experiment has accumulated ∼161 days of exposure during six successful flights over Antarctica. Energy measurements are made with a transition radiation detector and an ionization calorimeter. Charge measurements are made with timing scintillators, pixelated Si, and Cherenkov detectors to minimize the effect of backscattered particles. High energy cosmicray data were collected over a wide energy range from ∼ 1010 to ∼ 1015 eV at an average altitude of ∼ 38.5 km, with ∼ 3.9 g/cm2 atmospheric overburden. All cosmic-ray elements from protons (Z = 1) to iron nuclei (Z = 26) are separated with excellent charge resolution. Recent results from the ongoing analysis including the discrepant hardening of elemental spectra at ∼ 200 GeV/n are presented and their implications on cosmic-ray origin, acceleration and propagation are discussed. The project status and plans are also presented.

    Several aspects of the F N method are reported, and the method is used to solve accurately some benchmark problems in radiative transfer in the field of atmospheric physics. The method was modified to solve cases of pure scattering and an improved process was developed for computing the radiation intensity. An algorithms for computing several quantities used in the F N method was done. An improved scheme to evaluate certain integrals relevant to the method is done, and a two-term recursion relation that has proved useful for the numerical evaluation of matrix elements, basic for the method, is given. The methods used to solve the encountered linear algebric equations are discussed, and the numerical results are evaluated. (M.C.K.) [pt

Concurrent measurement of ν μ disappearance allows refined measurements of the atmospheric Δm 23 2 and of the θ 23 mixing parameters. Analysis of data taken from January 2010 to March 2011 led to the first indication to ν μ → ν e appearance, it means θ 13 ≠ 0 (2.5σ significance), opening the way to CP violation searches in the leptonic sector. Measurement for ν μ disappearance were performed as well. Data taking restarted in March 2012 at higher intensities. Results, data taking status and future plans will be discussed. (author)

    1979-01-01

    The all-sky surveys made with the A-2 instrument aboard HEAO-1 involved spectroscopy over a broad enough band width, with sufficient resolution, to obtain the basic spectral characteristics for two extreme aspects of the extragalactic X-ray sky. The overall spectrum (above 3 KeV) is remarkably well decribed by a thermal model. At the other extreme, the detailed broad-band observations of individual sources are restricted to objects within the present epoch. The objects include several individual active galaxies studied in detail for the first time as well as clusters of galaxies. Relating these results to the vast spatially unresolved hard X-ray flux measured with this instruments as well as the softer X-rays (at less than 3 keV) spatially resolved to high redshifts with the Einstein Observatory remains a challenge.

    Lead nucleus collisions in the LHC recreate the state of matter which existed when the universe was a few microseconds old. This super-hot matter, composed of quark and gluons, emits thousands of particles as it expands, cools and converts back into hadrons. The ATLAS detector provides an excellent opportunity to perform detailed studies of this novel state of matter, measuring its bulk properties and its response to penetrating probes. Recent studies of particle correlations and fluctuations shed light on the initial geometry and its evolution into the final state. Studies of jet suppression and fragmentation show how the energetic partons interact with the medium. High precision measurements of boson production and first results on boson-jet correlations are important steps towards quantitative understanding of the parton energy loss mechanism.

    2018-01-01

    Supersymmetry (SUSY) is considered one of the best motivated extensions of the Standard Model. It postulates a fundamental symmetry between fermions and bosons, and introduces a set of new supersymmetric particles at the electroweak scale. It addresses the hierarchy and natu- ralness problem, gives a solution to the gauge couplings unification, and offers a cold dark matter candidate. Different aspects of SUSY searches, using strong, electroweak, third generation production, R-parity violation models, and long lived particles are being studied at the LHC. An overview of most recent results in SUSY searches using Run 2 ATLAS data, at 13 TeV with 36.1 fb−1 of integrated luminosity, was presented.

    The KASCADE–Grande experiment, located at Karlsruhe Institute of Technology (Germany) is a multi-component extensive air-shower experiment devoted to the study of cosmic rays and their interactions at primary energies 10 14 –10 18 eV. Main goals of the experiment are the measurement of the all-particle energy spectrum and mass composition in the 10 16 –10 18 eV range by sampling charged (N ch ) and muon (N μ ) components of the air shower. The method to derive the energy spectrum and its uncertainties, as well as the implications of the obtained result, is discussed. An overview of the analyses performed by KASCADE–Grande to derive the mass composition of the measured high-energy comic rays is presented as well.

    The KASCADE-Grande experiment, located at Karlsruhe Institute of Technology (Germany) is a multi-component extensive air-shower experiment devoted to the study of cosmic rays and their interactions at primary energies 10{sup 14}-10{sup 18} eV. Main goals of the experiment are the measurement of the all-particle energy spectrum and mass composition in the 10{sup 16}-10{sup 18} eV range by sampling charged (N{sub ch}) and muon (N{sub {mu}}) components of the air shower. The method to derive the energy spectrum and its uncertainties, as well as the implications of the obtained result, is discussed. An overview of the analyses performed by KASCADE-Grande to derive the mass composition of the measured high-energy comic rays is presented as well.

    In 1988 the Danish government adopted an action plan for the environment and sustainable development. In 1990, the energy aspects of this plan were embodied in Energy 2000 and, in 1993, in Energy 2000 follow-up. The objective is a 20% reduction of CO{sub 2} emissions by the year 2005, compared with the level in 1988. Various measures are therefore being taken as time passes to help achieve this objective. As part of the monitoring of developments in the energy sector, it is necessary to take stock from time to time and to assess the direction in which the sector is moving. The government has therefore drawn up a new energy action plan, Energy 21, both to ensure that the overall objectives in the current plan are actively followed up on and to look ahead at the possibilities for action after the year 2005. The Danish Energy Agency has previously carried out a number of analyses of the technological and behavioural possibilities for reducing energy consumption in the short and the long term, for improving the efficiency of energy supply installations, and for using new and sustainable energy technologies. The results of this work are described in the report Denmark`s Energy Futures. The calculations in the report itself and its appendices. The more detailed assumptions and a description of the methods of analysis etc. are given in Basis for Analysis of Denmark`s Energy Futures. This report contains the assumptions, a description of methods and some of the results of the work on Energy 21. (au)

  15. Recent QCD Results from SLD

    1999-01-01

    We present selected results on strong interaction physics from the SLD experiment at the SLAC Linear Collider. We report on several new studies of 3- and 4-jet hadronic Z 0 decays, in which jets are identified as quark, antiquark or gluon. The 3-jet Z 0 --> b anti-bg rate is sensitive to the b-quark mass; prospects for measuring m b are discussed. The gluon energy spectrum is measured over the full kinematic range, providing an improved test of QCD and limits on anomalous b anti-bg couplings. The parity violation in Z 0 --> b anti-bg decays is consistent with electroweak theory plus QCD. New tests of T- and CP-conservation at the bbg vertex are performed. A new measurement of the rate of gluon splitting into b anti-b pairs yields g b anti-b = 0.0031 ± 0.0007 (stat.)± 0.0006 (syst.) (Preliminary). We also present a number of new results on jet fragmentation into identified hadrons. The B hadron energy spectrum is measured over the full kinematic range using a new, inclusive technique, allowing stringent tests of predictions for its shape and a precise measurement of (xB) = 0.714 ± 0.005(stat.) ± 0.007(syst.) (Preliminary). A detailed study of correlations in rapidity y between pairs of identified pi ± , K ± and p/anti-p confirms that strangeness and baryon number are conserved locally, and shows local charge conservation between meson-baryon and strange-nonstrange pairs. Flavor-dependent long-range correlations are observed for all combinations of these hadron species, yielding new information on leading particle production. The first study of correlations using rapidities signed such that y > 0 corresponds to the quark direction provides additional new insights into fragmentation, including the first direct observation of baryon number ordering along the q anti-q axis

    Two experiments, DCH-3 and DCH-4, were performed at the Surtsey test facility to investigate phenomena associated with a high-pressure melt ejection (HPME) reactor accident sequence resulting in direct containment heating (DCH). These experiments were performed using the same experimental apparatus with identical initial conditions, except that the Surtsey test vessel contained air in DCH-3 and argon in DCH-4. Inerting the vessel with argon eliminated chemical reactions between metallic debris and oxygen. Thus, a comparison of the pressure response in DCH-3 and DCH-4 gave an indication of the DCH contribution due to metal/oxygen reactions. 44 refs., 110 figs., 43 tabs

  18. RESULTS OF SUPPLEMENTAL MST STUDIES

    2006-01-01

    The current design of the Salt Waste Processing Facility (SWPF) includes an auxiliary facility, the Actinide Finishing Facility, which provides a second contact of monosodium titanate (MST) to remove soluble actinides and strontium from waste if needed. This treatment will occur after cesium removal by Caustic-Side Solvent Extraction (CSSX). Although the process changes and safety basis implications have not yet been analyzed, provisions also exist to recover the MST from this operation and return to the initial actinide removal step in the SWPF for an additional (third) contact with fresh waste. A U.S. Department of Energy (DOE) request identified the need to study the following issues involving this application of MST: Determine the effect of organics from the solvent extraction (CSSX) process on radionuclide sorption by MST; Determine the efficiency of re-using MST for multiple contacts; and Examine fissile loading on MST under conditions using a waste containing significantly elevated concentrations of plutonium, uranium, neptunium, and strontium. This report describes the results of three experimental studies conducted to address these needs: (1) Addition of high concentrations of entrained CSSX solvent had no noticeable effect, over a two week period, on the sorption of the actinides and strontium by MST in a direct comparison experiment. (2) Test results show that MST still retains appreciable capacity after being used once. For instance, reused MST--in the presence of entrained solvent--continued to sorb actinides and strontium. (3) A single batch of MST was used to sequentially contact five volumes of a simulant solution containing elevated concentrations of the radionuclides of interest. After the five contacts, we measured the following solution actinide loadings on the MST: plutonium: 0.884 ± 0.00539 wt % or (1.02 ± 0.0112) E+04 (micro)g/g MST, uranium: 12.1 ± 0.786 wt % or (1.40 ± 0.104) E+05 (micro)g/g MST, and neptunium: 0.426 ± 0.00406 wt % or

    Temperatures, densities and confinement of deuterium plasmas confined in tokamaks have been achieved within the last decade that are approaching those required for a D-T reactor. As a result, the unique phenomena present in a D-T reactor plasma (D-T plasma confinement, alpha confinement, alpha heating and possible alpha driven instabilities) can now be studied in the laboratory. Recent experiments on the Tokamak Fusion Test Reactor (TFTR) have been the first magnetic fusion experiments to study plasmas with reactor fuel concentrations of tritium. The injection of ∼ 20 MW of tritium and 14 MW of deuterium neutral beams into the TFTR produced a plasma with a T/D density ratio of ∼1 and yielded a maximum fusion power of ∼ 9.2 MW. The fusion power density in the core of the plasma was ∼ 1.8 MW m -3 approximating that expected in a D-T fusion reactor. A TFTR plasma with T/D density ratio of ∼ 1 was found to have ∼ 20% higher energy confinement time than a comparable D plasma, indicating a confinement scaling with average ion mass, A, of τ E ∼ A 0.6 . The core ion temperature increased from 30 keV to 37 keV due to a 35% improvement of ion thermal conductivity. Using the electron thermal conductivity from a comparable deuterium plasma, about 50% of the electron temperature increase from 9 keV to 10.6 keV can be attributed to electron heating by the alpha particles. The ∼ 5% loss of alpha particles, as observed on detectors near the bottom edge of the plasma, was consistent with classical first orbit loss without anomalous effects. Initial measurements have been made of the confined energetic alphas and the resultant alpha ash density. At fusion power levels of 7.5 MW, fluctuations at the Toroidal Alfven Eigenmode frequency were observed by the fluctuation diagnostics. However, no additional alpha loss due to the fluctuations was observed

    Full Text Available We consider implications of the Regional Earthquake Likelihood Models (RELM test results with regard to earthquake forecasting. Prospective forecasts were solicited for M≥4.95 earthquakes in California during the period 2006–2010. During this period 31 earthquakes occurred in the test region with M≥4.95. We consider five forecasts that were submitted for the test. We compare the forecasts utilizing forecast verification methodology developed in the atmospheric sciences, specifically for tornadoes. We utilize a “skill score” based on the forecast scores λfi of occurrence of the test earthquakes. A perfect forecast would have λfi=1, and a random (no skill forecast would have λfi=2.86×10-3. The best forecasts (largest value of λfi for the 31 earthquakes had values of λfi=1.24×10-1 to λfi=5.49×10-3. The best mean forecast for all earthquakes was λ̅f=2.84×10-2. The best forecasts are about an order of magnitude better than random forecasts. We discuss the earthquakes, the forecasts, and alternative methods of evaluation of the performance of RELM forecasts. We also discuss the relative merits of alarm-based versus probability-based forecasts.

    The Salt Decontamination Demonstration confirmed that the precipitation process could be used for large-scale decontamination of radioactive waste sale solution. Although a number of refinements are necessary to safely process the long-term requirement of 5 million gallons of waste salt solution per year, there were no observations to suggest that any fundamentals of the process require re-evaluation. Major accomplishments were: (1) 518,000 gallons of decontaminated filtrate were produced from 427,000 gallons of waste salt solution from tank 24H. The demonstration goal was to produce a minimum of 200,000 gallons of decontaminated salt solution; (2) cesium activity in the filtrate was reduced by a factor of 43,000 below the cesium activity in the tank 24 solution. This decontamination factor (DF) exceeded the demonstration goal of a DF greater than 10,000; (3) average strontium-90 activity in the filtrate was reduced by a factor of 26 to less than 10 3 d/m/ml versus a goal of less than 10 4 d/m/ml; and (4) the concentrated precipitate was washed to a final sodium ion concentration of 0.15 M, well below the 0.225 M upper limit for DWPF feed. These accomplishments were achieved on schedule and without incident. Total radiation exposure to personnel was less than 350 mrem and resulted primarily from sampling precipitate slurry inside tank 48. 3 references, 6 figures, 2 tables

    The Daya Bay Reactor Neutrino Experiment was designed to measure θ 13, the smallest mixing angle in the three-neutrino mixing framework, with unprecedented precision. The experiment consists of eight functionally identical detectors placed underground at different baselines from three pairs of nuclear reactors in South China. Since Dec. 2011, the experiment has been running stably for more than 4 years, and has collected the largest reactor anti-neutrino sample to date. Daya Bay is able to greatly improve the precision on θ 13 and to make an independent measurement of the effective mass splitting in the electron antineutrino disappearance channel. Daya Bay can also perform a number of other precise measurements, such as a high-statistics determination of the absolute reactor antineutrino flux and spectrum, as well as a search for sterile neutrino mixing, among others. The most recent results from Daya Bay are discussed in this paper, as well as the current status and future prospects of the experiment.

    A cobalt test assembly containing yttrium hydride pins for neutron moderation was irradiated in the Fast Flux Test Facility during Cycle 9A for 137.7 equivalent full power days at a power level fo 291 MW. The 36 test pins consisted of a batch of 32 pins containing cobalt metal to produce Co-60, and a set of 4 pins with europium oxide to produce Gd-153, a radioisotope used in detection of the bone disease Osteoporosis. Post-irradiation examination of the cobalt pins determined the Co-60 produced with an accuracy of about 5 %. The measured Co-60 spatially distributed concentrations were within 20 % of the calculated concentrations. The assembly average Co-60 measured activity was 4 % less than the calculated value. The europium oxide pins were gamma scanned for the europium isotopes Eu-152 and Eu-154 to an absolute accuracy of about 10 %. The measured europium radioisotpe anc Gd-153 concentrations were within 20 % of calculated values. In conclusion, the hydride assembly performed well and is an excellent vehicle for many Fast Flux Test Facility isotope production applications. The results also demonstrate that the calculational methods developed by the Westinghouse Hanford Company are very accurate. (author)

    The Procurement and Logistics functions have gone through a process of integration since the beginning of integrated management of Asco and Vandellos II up to the present. These are functions that are likely to be designed for delivering a single product to the rest of the organization, defined from a high level of expectations, and that admit simplifications and materialization of synergy's as they are approached from an integrated perspective. The analyzed functions are as follows: Service and Material Purchasing, Warehouse and Material Management, and Documentation and General Services Management. In all case, to accomplish the integration, objectives, procedures and information systems were unified. As for the organization, a decision was made in each case on whether or not to out source. The decisive corporate strategy to integrate, resulting in actions such as moving corporate headquarters to Vandellos II, corporate consolidation, regulation of employment and implementation of the ENDESA Group Economic Information System (SIE) , has shaped this process, which at present can be considered as practically complete.

    The results of a survey conducted by the Petroleum Technology Alliance Canada were presented. The survey identified ways in which companies in the oil and gas industry can reduce the potential for vehicle incidents, as well as improve fleet management techniques. Respondents provided a list of over 60 relevant technologies with high potential for application. Top driving safety challenges included adverse weather and road conditions, as well as driver attitude and awareness. Driver speed and fatigue were also seen as significant challenges, as well as encounters with wildlife and road conditions. Poor site conditions were also identified as a challenge, along with poor hazard recognition training, and lack of experience. A total of 157 representatives responded, whose fleets collectively drive approximately 136,500,000 km per year. The fleets totalled 15,800 vehicles. Respondents' affiliations with the oil and gas industry were included, as well as ownership classifications and company fleet sizes. Total annual fleet kilometers were presented, as well as the number of incidents per company per year, along with the number of respondents' animal strikes per year. tabs, figs.

  6. LSND results and their implications

    1996-01-01

    The combined 1993, 1994, and 1995 data from the LSND experiment shows a statistically compelling excess of events of the type expected for ν μ →ν e neutrino oscillations. An electron between 36 and 60 MeV is identified by Cherenkov and scintillation light from ν e p→e + n, and if a γ is tightly constrained to be correlated with it from np→dγ (2.2 MeV), then 22 such events are observed, but only 4.6±0.6 are expected from background. The probability that this is a fluctuation is -7 . If subsequent analysis shows a similar effect from the independent channel ν μ →ν e , then this would imply a neutrino mass difference which would contribute significantly to the dark matter of the universe. Explaining also the solar and atmospheric neutrino deficits results in a neutrino mass pattern which gives a cold + hot dark matter which fits the structure of the universe on all scales and requires a critical density universe and an universe age compatible with that of the oldest stars. This mass pattern involves a sterile neutrino, evidence for which may come from the need for it in producing heavy elements by supernovae and for blowing off the supernova mantle.

  8. Experimental results on evaporation waves

    Grana Otero, Jose; Parra Fabian, Ignacio

    2010-11-01

    A liquid contained in a vertical glass tube is suddenly depressurized from a high initial pressure down to one for which the stable state is vapour, so vaporization sets off at the free surface. For large enough evaporation rates, the planar vapour-liquid interface is Darrieus-Landau unstable [1], leading to the interface surface rippling close to the instability threshold. Further increasing the initial to final pressure ratio brings about evaporation waves [2,3], in which a highly corrugated front propagates downwards into the liquid. A new experimental method is presented as well as some experimental results obtained by tracking the evolution of the front with a high speed camera. In addition, a number of new phenomena related to the dynamics of bubbles growth at the walls has been uncovered. In particular, a new mode of propagation of the evaporation front is found. In this mode the front originates from below the interface, so the propagation is upwards against gravity with a curved but smooth front.[4pt] [1] F. J. Higuera, Phys. Fluids, V. 30, 679 (1987).[0pt] [2] J.E.Shepherd and B.Sturtevant, J.Fluid Mech., V.121,379 (1982).[0pt] [3] P.Reinke and G.Yadigaroglu, Int.J.Multiph. Flow, V.27,1487 (2001).

  9. Uncertainty of dustfall monitoring results

    2017-06-01

    Full Text Available Fugitive dust has the ability to cause a nuisance and pollute the ambient environment, particularly from human activities including construction and industrial sites and mining operations. As such, dustfall monitoring has occurred for many decades in South Africa; little has been published on the repeatability, uncertainty, accuracy and precision of dustfall monitoring. Repeatability assesses the consistency associated with the results of a particular measurement under the same conditions; the consistency of the laboratory is assessed to determine the uncertainty associated with dustfall monitoring conducted by the laboratory. The aim of this study was to improve the understanding of the uncertainty in dustfall monitoring; thereby improving the confidence in dustfall monitoring. Uncertainty of dustfall monitoring was assessed through a 12-month study of 12 sites that were located on the boundary of the study area. Each site contained a directional dustfall sampler, which was modified by removing the rotating lid, with four buckets (A, B, C and D installed. Having four buckets on one stand allows for each bucket to be exposed to the same conditions, for the same period of time; therefore, should have equal amounts of dust deposited in these buckets. The difference in the weight (mg of the dust recorded from each bucket at each respective site was determined using the American Society for Testing and Materials method D1739 (ASTM D1739. The variability of the dust would provide the confidence level of dustfall monitoring when reporting to clients.

    The aim of present study was to evaluate the results of using stapedectomy to treat tympanosclerosis fixation of footplate. It is a retrospective review of tympanosclerosis of the oval window with stapes fixation, after undergoing surgery. Eight patients underwent stapedectomy for tympanosclerotic stapes. Postoperative post-op air-bone gap ABG closure to within 10 dB was achieved in 25% of the cases. An ABG of less than 20 db was obtained in 87.5% of the cases. The mean preoperative pre-op ABGs were 31.09 dB. Significant post-op improvement of air conduction thresholds more than, or equal to 20dB was found in 62.5% of cases. No significant sensorineural hearing loss was seen in this series with a mean pre-op bone-conduction threshold BC of 23.43 dB and a mean post-op BC threshold of 16.25 dB. The mean follow-up period was 6.5 months. (author)

    For many years, the petroleum industry has been developing a valve that input less shear to the flow for a given required pressure drop and this can be done using the cyclonic concept. This paper presents a comparison between the performances of a cyclonic valve (low shear) and a conventional globe valve. The aim of this work is to show the advantages of using a cyclonic low shear valve instead of the commonly used in the primary separation process by PETROBRAS. Tests were performed at PETROBRAS Experimental Center (NUEX) in Aracaju/SE varying some parameters: water cut; pressure loss (from 4 kgf/cm2 to 10 kgf/cm2); flow rates (30 m3/h and 45 m3/h). Results indicates a better performance of the cyclonic valve, if compared with a conventional one, and also that the difference of the performance, is a function of several parameters (emulsion stability, water content free, and oil properties). The cyclonic valve tested can be applied as a choke valve, as a valve between separation stages (for pressure drop), or for controlling the level of vessels. We must emphasize the importance to avoid the high shear imposed by conventional valves, because once the emulsion is created, it becomes more difficult to break it. New tests are being planned to occur in 2012, but PETROBRAS is also analyzing real cases where the applications could increase the primary process efficiency. In the same way, the future installations are also being designed considering the cyclonic valve usage. (author)

    2010-01-01

    The Majorana demonstrator will operate at liquid Nitrogen temperatures to ensure optimal spectrometric performance of its High Purity Germanium (HPGe) detector modules. In order to transfer the heat load of the detector module, the Majorana demonstrator requires a cooling system that will maintain a stable liquid nitrogen temperature. This cooling system is required to transport the heat from the detector chamber outside the shield. One approach is to use the two phase liquid-gas equilibrium to ensure constant temperature. This cooling technique is used in a thermosyphon. The thermosyphon can be designed so the vaporization/condensing process transfers heat through the shield while maintaining a stable operating temperature. A prototype of such system has been built at PNNL. This document presents the experimental results of the prototype and evaluates the heat transfer performance of the system. The cool down time, temperature gradient in the thermosyphon, and heat transfer analysis are studied in this document with different heat load applied to the prototype.

    The Double Chooz experiment has been observing ν{sup ¯}{sub e} from two reactor cores at the Chooz nuclear power station in Ardennes, France, with a single 10.3 m{sup 3} fiducial volume Gd-doped liquid scintillator detector at a flux-weighted average baseline of ∼1050 m. This article reviews results achieved with a detector live time of 227.93 days and exposure of 33.71 GW-ton-years. A total of 8,249 candidate ν{sup ¯}{sub e} events have been observed, compared to an expected 8,937 events in the null-oscillation case: this deficit is interpreted as evidence for ν{sup ¯}{sub e} disappearance. A fit to the observed neutrino rate and spectral shape gives a best-fit value of sin{sup 2}(2θ{sub 13})=0.109±0.030(stat.)±0.025(syst.) at a mass-squared splitting of Δm{sub 31}{sup 2}=2.32×10{sup −3} eV{sup 2}. The null-oscillation hypothesis is excluded by the data at 99.8% CL (2.9σ). The Double Chooz Near Detector is under construction, and analysis efforts to measure neutrino directionality, test Lorentz violation, and measure backgrounds in situ are underway.

Concern has been expressed that polyethylene air/vapour barriers degrade over time. This concern has led various agencies to test and retest homes for air leakage. This report is the compilation of the data collected as a result of that testing. Raw data were collected on 145 homes from various sources. Data were screened and the tests of homes were omitted from the analysis if the fan tests were done on the same house by different firms, if the construction of the house was not sufficiently complete, or if the initial air change rate per hour (ACH) was greater than 3. With these omissions from the database, 90 homes remained to be analyzed. The 90 homes were separated into two groups, those with an initial ACH less than 1.5 and those with an initial ACH between 1.5 and 3.0. The data were recorded in two tables which included the ACH, the time in months, the percentage change, and the difference in change between the first test and each subsequent test. These data indicate a relatively minor average change in airtightness. Keeping in mind the quantity of data collected the time period examined, there is no indication that significant problems exist that would necessitate a change to the current building practice. 2 figs., 5 tabs.

    The combined 1993, 1994, and 1995 data from the LSND experiment shows a statistically compelling excess of events of the type expected for {nu}{sub {mu}} {yields}{nu}{sub e} neutrino oscillations. An electron between 36 and 60 MeV is identified by Cherenkov and scintillation light from {nu}{sub e}p{yields}e{sup +}n, and if a {gamma} is tightly constrained to be correlated with it from np{yields}d{gamma} (2.2 MeV), then 22 such events are observed, but only 4.6{+-}0.6 are expected from background. The probability that this is a fluctuation is <10{sup -7}. If subsequent analysis shows a similar effect from the independent channel {nu}{sub {mu}}{yields}{nu}{sub e}, then this would imply a neutrino mass difference which would contribute significantly to the dark matter of the universe. Explaining also the solar and atmospheric neutrino deficits results in a neutrino mass pattern which gives a cold + hot dark matter which fits the structure of the universe on all scales and requires a critical density universe and an universe age compatible with that of the oldest stars. This mass pattern involves a sterile neutrino, evidence for which may come from the need for it in producing heavy elements by supernovae and for blowing off the supernova mantle.

    2011-01-01

    We present the results of electroweak studies performed using data collected in 2010 at a center-of-mass energy of 7 TeV by the CMS experiment at the LHC. Besides their intrinsic interest as unique samples to calibrate and understand the CMS detector response to leptons, jets and missing energy, events containing W and Z bosons appear as dominant components in many Higgs seaches and in most of the searches beyond the Standard Model, either as signal or as background. In addition, the excellent level of theoretical and experimental understanding of these processes allows electroweak tests at the LHC at an unprecendented level of precision. CMS uses a wide range of final states to measure cross sections, asymmetries, polarizations and differential distributions in general. The current integrated luminosity is already sufficient to perform not just inclusive measurements using W and Z decays into muons and electrons, but also precise studies of associated jet production and final states containing taus, as well...

    Full Text Available Introduction Penile fracture is a urological emergency caused by direct trauma to an erected penis, tearing the tunica albuginea in the corpus cavernosum. The preferred treatment method is draining the hematoma and surgical repair of tunica albuginea tear as soon as possible following diagnosis. Materials and Methods Forty-nine patients who were diagnosed with penile fracture between January 2009 and December 2014 were reviewed. Physical examination was performed to see the extent of penile hematoma, the side of the penile curvature and the presence of blood in the external meatus. Two patients who were diagnosed with urethrorrhagia underwent retrograde urethrogram for urethral injury. In all patients, penile skin was peeled using a circular subcoronal degloving incision and tunica tear was repaired using absorbable suture materials. The patients were then followed for painful erections, penile deformities and erection angles. Results The average age of the 49 patients, who were included in the study, was 36.5 years (21-65. In their etiological questioning, most patients reported the fracture occurring during sexual intercourse. Retrograde urethrography was indicated in 2 patients with blood in the external meatus and were diagnosed with urethral injury. The patients were taken to emergency surgery. Tunica defects varied between 1 and 2 cm. Incomplete urethral injuries were primarily repaired around 18 French Foley catheter. None of the patients reported penile deformity or painful erections. Their erection angles were found to be within the normal range. Conclusion Even though it is a relatively rare condition, penile fractures are so important that might cause serious complications when not treated surgically. A thorough anamnesis and physical examination suffice for diagnosis.

  20. Public Administration reforms and results

    Full Text Available Research on administrative reforms during the past thirty years indicates that reform efforts of countries differ. The Anglo Saxon states were at the forefront of the New Public Management movement while countries on mainland Europe were more hesitant and moved further towards the Neo-Weberian state. Academics have tried to explain different reform efforts within countries by looking at political, historical and cultural issues, values and economic factors to name just a few. Three hypotheses are put forward to explain reform efforts in different states. This research involves analysing the implementation of two different reform trends, New Public Management and the Neo-Weberian tradition. The analysis indicates that countries vary in their commitment to reform rather than in the emphasis on either New Public Management or the Neo-Weberian State. Decentralization, clear objectives and consultation with communities and experts are closely related to national reform efforts. However, Iceland does distinguish itself from Europe and the Nordic countries. The analysis reveals that although decentralization is high in the Icelandic system, autonomy of agencies does not have a strong relation to a varied use of administrative instruments. The second part of the article focuses on the results and achievements of reform programmes. The achievement of reform programmes are examined in relation to theories of bounded rationality, street level bureaucracy (bottom up and consensus decision making. Three hypotheses are presented and tested to explain what causes reforms programmes to be successful in some countries and not in others. The analysis reveals that countries are more likely to succeed if bounded rationality is applied with careful preparation and when stakeholders are consulted.

    1975-01-01

    The first results of proceeding some data collected by the 'Orion-2' observatory set up in the 'Soyuz-13' are presented. The goal of the experiment is to get the photographs of ultraviolet (UV) spectra of weak stars in the range of 2000-5000 A. Spectrograms are obtained for stars with brightness of 9-9.5 stellar magnitude at 1.5 min exposure. It has been possible to take spectrograms of many stars weaker than the 12-th magnitude at the 18 min exposure and at the short-wave boundary of a spectrum of 2500 A. A group of stars of an unknown type has been observed not far from Capella. The group contains approximately twenty stars weaker than the 10-th photographic magnitude. The average position of the group is α=0.5sup(m)10sup(m), delta=+44deg30'. Spectrograms of more than twenty hot stars in the Sails constellation in the South Sky are obtained. According to the 'Orion-2' data the light absorption in the interstellar space in the range of 2000-3000 A is caused by graphite particles of an almost spheric shape, that is in accordance with present assumptions. In spectra of over 100 stars the doublet of ionized magnesium, 2800 Mg 2, has been distinguished and measured. Spectral photographs made by the 'Orion-2' allow one to reveal chromosphere of cool stars. A strange star is discovered (12sup(m),6 brigthness in photographic rays) not far from Capella, its spectrum displaying many emission lines. A unique spectrogram of the NGC 2 2149 planetary nebula and its nucleus has been obtained. The question is whether it is possible to classify stars not only by their lines but also by the continuous UV spectrum up to 2000 A. This method may turn out to be very effective for weak stars. The 'Orion-2' has demonstrated ample possibilities of carrying out astrophysical researches outside the atmosphere

    1997-05-01

    Laboratory corrosion tests were conducted on eight candidates to select a durable and cost-effective alloy for use in mobile evaporators to process radioactive waste solutions. Based on an extensive literature survey of corrosion data, three stainless steel alloys (304L, 316L, AL-6XN), four nickel-based alloys (825, 625, 690, G-30), and titanium were selected for testing. The corrosion tests included vapor phase, liquid junction (interface), liquid immersion, and crevice corrosion tests on plain and welded samples of candidate materials. Tests were conducted at 80 degrees C for 45 days in two different test solutions: a nitric acid solution. to simulate evaporator conditions during the processing of the cesium ion-exchange eluant and a highly alkaline sodium hydroxide solution to simulate the composition of Tank 241-AW-101 during evaporation. All of the alloys exhibited excellent corrosion resistance in the alkaline test solution. Corrosion rates were very low and localized corrosion was not observed. Results from the nitric acid tests showed that only 316L stainless steel did not meet our performance criteria. The 316L welded interface and crevice specimens had rates of 22.2 mpy and 21.8 mpy, respectively, which exceeds the maximum corrosion rate of 20 mpy. The other welded samples had about the same corrosion resistance as the plain samples. None of the welded samples showed preferential weld or heat-affected zone (HAZ) attack. Vapor corrosion was negligible for all alloys. All of the alloys except 316L exhibited either open-quotes satisfactoryclose quotes (2-20 mpy) or open-quotes excellentclose quotes (<2 mpy) corrosion resistance as defined by National Association of Corrosion Engineers. However, many of the alloys experienced intergranular corrosion in the nitric acid test solution, which could indicate a susceptibility to stress corrosion cracking (SCC) in this environment

    Visual servoing techniques consist in using the data provided by a vision sensor in order to control the motions of a dynamic system. Such systems are usually robot arms, mobile robots, aerial robots,… but can also be virtual robots for applications in computer animation, or even a virtual camera for applications in computer vision and augmented reality. A large variety of positioning tasks, or mobile target tracking, can be implemented by controlling from one to all the degrees of freedom of the system. Whatever the sensor configuration, which can vary from one on-board camera on the robot end-effector to several free-standing cameras, a set of visual features has to be selected at best from the image measurements available, allowing to control the degrees of freedom desired. A control law has also to be designed so that these visual features reach a desired value, defining a correct realization of the task. With a vision sensor providing 2D measurements, potential visual features are numerous, since as well 2D data (coordinates of feature points in the image, moments, …) as 3D data provided by a localization algorithm exploiting the extracted 2D measurements can be considered. It is also possible to combine 2D and 3D visual features to take the advantages of each approach while avoiding their respective drawbacks. From the selected visual features, the behavior of the system will have particular properties as for stability, robustness with respect to noise or to calibration errors, robot 3D trajectory, etc. The talk will present the main basic aspects of visual servoing, as well as technical advances obtained recently in the field inside the Lagadic group at INRIA/INRISA Rennes. Several application results will be also described.

    1998-03-01

    This report describes the results of a functional and operational assessment of the Corral Monitoring Systems (CMS), which was designed to detect and document accountable items entering or leaving a monitored site. Its development was motivated by the possibility that multiple sites in the nuclear weapons states of the former Soviet Union might be opened to such monitoring under the provisions of the Strategic Arms Reduction Treaty. The assessment was performed at three levels. One level evaluated how well the planned approach addressed the target application, and which involved tracking sensitive items moving into and around a site being monitored as part of an international treaty or other agreement. The second level examined the overall design and development approach, while the third focused on individual subsystems within the total package. Unfortunately, the system was delivered as disassembled parts and pieces, with very poor documentation. Thus, the assessment was based on fragmentary operating data coupled with an analysis of what documents were provided with the system. The system design seemed to be a reasonable match to the requirements of the target application; however, important questions about site manning and top level administrative control were left unanswered. Four weaknesses in the overall design and development approach were detected: (1) poor configuration control and management, (2) inadequate adherence to a well defined architectural standard, (3) no apparent provision for improving top level error tolerance, and (4) weaknesses in the object oriented programming approach. The individual subsystems were found to offer few features or capabilities that were new or unique, even at the conceptual level. The CMS might possibly have offered a unique combination of features, but this level of integration was never realized, and it had no unique capabilities that could be readily extracted for use in another system

  6. FIRST RESULTS FROM OEDOTENSIOMETRIC TESTS

    Full Text Available An oedotensiometer was used to examine to examine the behaviour of sieved sample of a swelling soil (a vertisol as well as of the same soils treated with solution of Na+ + Ca2+ to simulate the soil changes from excessive irrigation with brackish water. The oedometer test consisted in an infiltration of water from below through a ceramic porous plate at a feeding pressure of +10 cm water and successive drainage under a depression mostly of -112 cm of water. The rate of water entry as well as the swelling rate of the sample were monitored. Preliminary considerations regards the domains in which the shrinkage curve of a swelling soil is subdivided and make hypothesis on the swelling process expected when the infiltration from below of the sample is applied. The results support the hypothesis that when the water pressure is applied some water enters rather rapidly in the larger structural pores and is followed later by the swelling in the smaller pores, responsible for the basic domain. This first conclusion demonstrates that the assumption of a simultaneous movement of solid and liquid components in the sample, which is the base of most theoretical developments for swelling soils, cannot be accepted for the tested samples. Some cases with water clogging on the sample surface confirm a late final swelling of the soil and permitted to evaluate the hydraulic conductivity of the swollen soil. These manifestations are more evident in sodicated soils. The loading of the sample reduces the swelling of the sample and seems to reduce its permeability. The reduction of the feeding water pressure further reduces the sample swelling. The draining process from saturated soil sample shows that most of the process occurs in the large pores of the structural domain. This gives the possibility to evaluate the water diffusivity coefficient for the structural domain of the sample. In draining the soil with the highest sodication there was a variation of soil volume

    Aerosol Trapping In a Steam Generator (ARTIST) is a seven-phase international project (2003-2007) which investigates aerosol and droplet retention in a model steam generator under dry, wet and accident management conditions, respectively. The test section is comprised of a scaled steam generator tube bundle consisting of 270 tubes and three stages, one 1:1 separator unit, and one 1:1 dryer unit. As a prelude to the ARTIST project, four tests are conducted in the ARTIST bundle within the 5th EU FWP SGTR. These first tests address aerosol deposition phenomena on two different scales: near the tube break, where the gas velocities are sonic, and far away from the break, where the flow velocities are three orders of magnitude lower. With a dry bundle and the full flow representing the break stage conditions, there is strong evidence that the TiO 2 aerosols used (AMMD 2-4 μm, 32 nm primary particles) disintegrate into much smaller particles because of the sonic conditions at the break, hence promoting particle escape from the secondary and lowering the overall DF, which is found to be between 2.5 and 3. With a dry bundle and a small flow reproducing the far-field velocities, the overall bundle DF is of the order of 5, implying a DF of about 1.9 per stage. Extrapolating the results of the dry tests, it turns out that for steam generators with nine or more stages, it is expected that substantial DF's could be achieved when the break is located near the tube sheet region. In addition, better decontamination is expected using more representative proxies of severe accident aerosols (sticky, multi-component particles), a topic which is yet to be investigated. When the bundle is flooded, the DF is between 45 and 5740, depending on the mass flow rate, the steam content, and the water submergence. The presence of steam in the carrier gas and subsequent condensation inside the broken tube causes aerosol deposition and blockages near the break, leading to an increase in the

    The Supervisory Board of the AREVA group presents in this document the financial statements submitted by the Executive Board for the semester ended June 30, 2010. Areva backlog continued to rise in the first half of the year. Areva's revenue is up by more than 6% for the first six months to more than 4 billion euros. The performance of Areva's recurring business continues to improve, reflecting optimization plans deployed in all of the group's business units. However, Areva booked in the first half a non cash reversible accounting adjustment on the value of certain mining assets, following the publication in the second quarter of new prospective data on uranium prices, as well as an additional provision on the EPR project in Finland. Cumulated provisions on OL3 rose to 2.6 billion euros. Capitalizing on lessons learned from this project, Areva has reduced strongly the engineering hours needed for the completion of the nuclear steam supply system for the Taishan 1 and 2 EPR reactors. Net income attributable to owners of the parent rose to 843 million euros, including the 1.3 billion euro gain on the disposal of the Transmission and Distribution business, or 23.82 euros per share. For the full year of 2010, the group anticipates a substantial revenue and backlog growth, an increase in operating income excluding particular items, a negative operating income, and a strong increase in net income attributable to owners of the parent, which includes the capital gain on disposal of the Transmission and Distribution business. First half 2010 financial results in brief: - Backlog of euro 44.1 bn: +euro 1.2 bn compared with June 30, 2009; - Revenue of euro 4.158 bn: +6.4% compared with first half 2009; - Operating income excl. particular items: euro 213 m, for a 5.1% margin; - Operating income: -euro 485 m; - Net income group share: euro 843 m including the euro 1.27 bn gain on the sale of the T and D business; - Earnings per share: euro 23.82; - Net debt of euro 5.152 bn

    The eosin-5'-maleimide (EMA) Binding test measures reduced mean channel fluorescence (MCF) reading of EMA-labeled red cells (EMA-RBCs) from patients with hereditary spherocytosis (HS). Reporting test results can be either in the actual MCF reading or as a ratio by normalization of the test MCF result to the mean MCF value of six normal controls. The latter format has potential for universal reporting. We analyzed three years' archival MCF data from HS and non-HS patient groups for establishment of reference ranges of ratios for normal adults and HS. A prospective study used FC500 and FACS Canto II cytometers to analyze contemporaneously EMA-RBCs from several patient groups and normal donors. Statistical analyses of the prospective data determined the cut-off values, and the sensitivity and specificity for HS respectively for the MCF and the ratio result presentations. The effect of using fewer than six normal controls for the ratio denominator was explored. The FC500 gave a mean ratio of 0.782 (SD=0.086) in HS patients with an optimal cut-off ratio of 0.918 (98.7% specificity, 95.6% sensitivity), and gray area ratio of 0.868-0.918. The Canto II gave a mean ratio of 0.774 (SD=0.085) with an optimal cut-off ratio of 0.925 (97.1% specificity and 100% sensitivity), and gray area ratio of 0.859-0.925. Harmonization of result presentation is feasible with no apparent constraint by instrument design. Interpretation of gray-area data requires an assessment of patient's clinical presentation and family history or performing a family study. © 2014 Clinical Cytometry Society.

Methods: 229 patients with chronic periodontitis from USA (n=134 and Sweden (n=95 were randomly assigned to eight groups receiving 1 scaling+root planing (SRP alone or combined with 2 surgery (SURG+systemic amoxicillin (AMOX+systemic metronidazole (MET; 3 SURG+local tetracycline (TET; 4 SURG; 5 AMOX+MET+TET; 6 AMOX+MET; 7 TET; and 8 SURG+AMOX+MET+TET. Antibiotics were given immediately after SRP. Plaque, gingival redness, bleeding on probing, suppuration, PD, and CAL were recorded at baseline and after 3, 6, 12, 18, and 24 months. Treatment effects were evaluated by linear multilevel regression and logistic multilevel regression models. We considered only data from sites with a baseline PD of at least 5 mm of 187 patients completing the study. Results: Surgically treated patients experienced most CAL loss. Adjunctive therapy including SURG was most effective in reducing PD. Combining SURG with AMOX, MET, and TET gave significant clinical benefits. Past and current smoking habits were significant predictors of deeper PD. Only current smoking was a significant predictor of CAL loss. Bleeding, accumulation of plaque, gingival redness, and suppuration were significant predictors of further CAL loss and deeper PD. Conclusions: Both surgical and non-surgical therapies can be used to arrest chronic periodontitis. SURG+AMOX+MET+TET gave best maintenance of clinical results.

The data for this study was drawn from TIMSS 2015 data which included test results and responses to Teacher Questionnaire. Descriptive statistics was used to analyze the data. Indonesian textbooks were also analyzed to portrait a broader scope of possible reasons for students' low performance. The analysis of TIMSS test result reveals that Indonesian students, in comparison to students from other countries, had low understanding of the basic concepts of fractions. From the Teacher Questionnaire it was found that a possible reason for this low understanding was the Indonesian curriculum for third grade which gave low emphasis on the basic concepts of fractions and introduced operations of fractions rather early. Furthermore, the result of textbook analysis shows that Indonesian textbooks restricted only to one definition of fractions, i.e. fractions as parts of wholes. This finding might also explain Indonesian fourth graders' low understanding of fractions.

    The testing facility measurement methods and results of prototype distributed ion pump (DIP) designs for the PEP-II B-Factory High Energy Ring are presented. Two basic designs with 5- or 7-anode plates were tested at LLNL with penning cell sizes of 15, 18, and 21 mm. Direct comparison of 5- and 7-plate anodes with 18 mm holes shows increased pumping speed with the 7-plate design. The 5-plate, 18 mm and 7-plate, 15 mm designs both gave an average pumping speed of 135 1/s/m at 1 {times} 10{sup {minus}8} Torr nitrogen base pressure in a varying 0.18 T peak B-field. Comparison of the three hole sizes indicates that cells smaller than the 15 mm tested can be efficiently used to obtain higher pumping speeds for the same anode plate sizes used.

    The prevision of the behavior of the 1/6 scale concrete model under internal pressure was realized by means of two computations, the first one with an infinite soil rigidity, the second one with a soil rigidity equal to 61.26 MPa/m. These two computations, that assumed a perfectly axisymetric structure gave theoretical and experimental results in good agreement, except the raft of which the theoretical uplift was three times higher than the experimental one. The main conclusions of this study are as follow: the soil stiffness has no influence on the ultimate behavior of the model, the dead concrete rigidity decreases the raft uplift in an important way, the model is destroyed because the hoop stress reaches the ultimate strength

    The results obtained in four successive trials based on the analysis of urography performed on patients with normal kidney function are reported. The scores obtained with a non-ionic contrast (Iopamidol) were compared with those produced after injecting the same contrast medium with the addition of various diuretics (furosemide, various quantitives of 5% glucose solution, 20% mannitol). The results obtained by injecting the diuretic together with the Iopamidol were usually unsatisfactory. Injection of diuretic 15 ms after the Iopamidol gave better results in the lower urinary tract, particularly the bladder. The best results were obtained by injecting 250 ml, 20% mannitol, after 15 ms. However this technique is not applicable to patients requiring a voiding cystourethrogram due to the inadequate opacification of the urethra it provides

    Two different types of accelerators have been used for production of ({sup 18}F)fluoride, and the isotope produced has been used for radiolabelling of 2-fluoro-2-deoxy-D-glucose (2-{sup 18}FDG). A rotating PET scanner, based on two scintillation camera heads, has been developed and used for human 2-{sup 18}FDG studies. The suitability of an energy window in the Compton region for imaging 511 keV photons in scintillation camera systems has been evaluated. A new simplified method for normalizing clinical 2-{sup 18}FDG results has been developed and validated, using erythrocytes as a reference tissue, requiring only one blood sample in the middle of the PET scan to calculate the integrated 2-{sup 18}FDG input function with an accuracy better than 8 percent. An investigation using 2-{sup 18}FDG PET to monitor the effect of therapy in advanced head and neck cancer patients has been performed. We found that low initial metabolic rate of glucose (MRG) predicted a complete local response. The second PET examination gave no further information for this group. In the group of primary tumours and lymph node metastases representing a combination of high initial MRG and small decrease in MRG at he second PET examination, the outcome was unfavourable. An accurate normalization of 2-{sup 18}FDG uptake was essential to evaluate the results of this study. 239 refs, 10 tabs.

  1. The UK Smoke Constituents Testing Study. Summary of Results and Comparison with Other Studies

    Full Text Available At the request of the UK Department of Health, samples of 25 commercial UK cigarette brands were provided to LGC Ltd a for smoke analysis. The brands reflected a high market share (58% in July 2001 and included a wide range of blend and product styles manufactured and imported into the UK.= 0.76, suggesting a minor role of other design features on constituents yield variability. This was confirmed by the application of multiple regression analysis to the data. A subset of five brands, retested at another laboratory, gave between-laboratory differences in mean constituent yields of as much as 2.5-fold. Consideration of these results, other likely sources of analytical variation in this study and a review of other studies, clearly indicates that any tolerance values to be associated with individual smoke constituent measurements will be greater than those for NFDPM, and in some cases, much greater. Consistent with the reported results from other large studies it is concluded that, under ISO smoking conditions, smoke constituent yields are largely predictable, if NFDPM and CO yields are known, for a standard cigarette. Given these observations and the likely limitations of analytical determination, the need for routine measurement of smoke constituent yields, other than NFDPM, nicotine or CO, on standard cigarettes, is questionable.

    Full Text Available The Croatian-Hungarian border section of the Dráva River has been undisturbed for almost a century, and it is characterised by unique fluvial morphology (braided pattern and islands supporting rich habitats and wildlife. However, during the last decades human impact became more and moreintensive. Between 1975 and 1989 three water reservoirs were built on the Croatian section of the river, just 16 km from the beginning of the border-section, altering the hydrology and the sediment characteristics of the river. On a local scale cut-offs, revetments and groynes were built. The aim of the study was to evaluate the effect of these human interventions. As the result of the alteration of the hydrology the channel pattern of the Dráva has been changing from braided to meandering, though on the upstream meandering part the territory and number of islands increased due to the drop of water stages. A cut-off and a groyne influenced only the morphology of a short section. As the result of the cut-off braided pattern became more pronounced, and the groyne caused intensive channel aggradation and gave way to lateral island development.

    evaluate the efficacy of a nursing intervention based on active observation and resolution of the problems of breastfeeding in the period 24-48h post-partum as regards stopping breastfeeding in mothers who gave birth in Hospital General Universitario, Ciudad Real. A clinical trial was conducted on 100 healthy women who had given birth to a healthy baby in the maternity unit of the Hospital General Universitario Ciudad Real. The results showed that 39.8% of women have problems, and 72% need help to initiate the breastfeeding. Approximately 79.9% continue with breastfeeding after hospital discharge as a result of our intervention. Breastfeeding was stopped by 31.1% of the control group, and by 10.9% in the experimental group (nursing intervention), with significant differences being observed in both groups, with RR 1.29 and 95% CI; 1.04-1.61. Hypogalactia (low milk production) was the most frequent reason for stopping, with no differences in both groups. At 3 months, 16.9% had stopped breastfeeding in the control group, and 9% in the experimental group. At 6 months, 19.3% of the control group did not continue with breastfeeding versus 15.9% in the experimental group. Action, and not only intervention, protocols in the period 48h pospartum when there were problems with breastfeeding were effective for initiation breastfeeding at hospital discharge.

    the purpose of this study was to analyze our preliminary results obtained with the KineSpring system in patients suffering from medial compartment knee osteoarthritis (OA). between September 2012 and May 2014, 53 patients underwent treatment with the KineSpring system. Patient self-assessment was performed pre-operatively and at 3, 6 and 12 months postoperatively, and included the KOOS, Tegner activity score, Lysholm functional knee score, VAS knee pain score, and IKDC score. Device- and procedure-related adverse events were recorded. mean KOOS subscales, except for the Sport/Recreation subscale at six months, improved over time. Mean WOMAC Pain and Function domains, Lysholm score, IKDC score and VAS knee pain score improved over the follow-up period and were significantly improved at 3, 6 and 12 months postoperatively compared to baseline. Mean Tegner score improved slightly over time. In 5 of the 53 (9.4%) patients re-operation was necessary. In 3 patients the device was removed due to infection (one case) or persistent knee pain (two cases). Surgical arthrolysis was performed in two patients. in our preliminary experience, the KineSpring system gave good short-term clinical results. Level IV, therapeutic case series.

    The Intergovernmental Panel on Climate Change gave a methodology to estimate the methane emissions from Municipal Solid Wastes landfills, based on a First Order Decay (FOD) model that assumes biodegradation kinetics depending on the type of wastes. This model can be used to estimate both the National greenhouse gas emissions in the industrialized countries as well as the reductions of these emissions in the developing ones when the Clean Development Mechanism, as defined by the Kyoto Protocol, is implemented. In this paper, the FOD model has been use to evaluate the biogas flow rates emitted by a Brazilian landfill and the results have been compared to the extracted ones: some first results can be useful to evidence the weight of key parameters and do a correct use of the model. - Highlights: ► Landfill biogas is greenhouse gas and fuel at the same time. ► In developing countries its collection can implement Kyoto Protocol mechanisms. ► Biogas collection and exploiting become part of energy policy. ► Project economical balance is based on reliable estimates of generated quantities.

The largest number of patients referred, to age interval from 11 to 30 years (69,6%. More than half of cases were osteochondromas (54%, then solitary bone cyst (14,5% and chondromas (13%. Other nosologic forms were met significantly seldom. Two groups of patients were examined: the main group (with crio-influence - 44 patients and group of comparison (without crio-influence - 87 patients. The plot of operation was in flat, border-line, intrafocusal or segmental resection of damaged section, crio-instillation or contact curio-processing of bone and auto- or allopathic of respected defect. The results of treatment were estimated in a year after operation. After usage of curio-surgical method there were observed positive results in 41 patients, satisfactory - in 2 and unsatisfactory - in 1. The results of treatment with traditional method were positive in 79 cases, satisfactory - in 2, unsatisfactory - in 6. The worked-out method of curio-surgical treatment of foot bone tumours includes resection of pathological focus, itraoperative crio-influence on bone tissue and bone plastic transplantation of resected, defect. The analysis of criosurgical operations of foot gave the foundation to consider such interventions significant and perspective in treatment of patients with tumours and tumour similar damages of foot bone.

    Full Text Available A study of soil erosion rates had been done on a slightly and long slope of cultivated area in Ciawi - Bogor, using 137Cs technique. The objective of the present study was to evaluate the applicability of the 137Cs technique in obtaining spatially distributed information of soil redistribution at small catchment. This paper reports the result of the choice of conversion model for erosion rate estimates and the sensitive of the changes in the model parameter. For this purpose, small site was selected, namely landuse I (LU-I. The top of a slope was chosen as a reference site. The erosion/deposit rate of individual sampling points was estimated using the conversion models, namely Proportional Model (PM, Mass Balance Model 1 (MBM1 and Mass Balance Model 2 (MBM2. A comparison of the conversion models showed that the lowest value is obtained by the PM. The MBM1 gave values closer to MBM2, but MBM2 gave a reliable values. In this study, a sensitivity analysis suggest that the conversion models are sensitive to changes in parameters that depend on the site conditions, but insensitive to changes in  parameters that interact to the onset of 137Cs fallout input.   Keywords: soil erosion, environmental radioisotope, cesium

    Spider silk is a tear-resistant and elastic biopolymer that has outstanding mechanical properties. Additionally, exiguous immunogenicity is anticipated for spider silks. Therefore, spider silk represents a potential ideal biomaterial for medical applications. All known spider silk proteins, so-called spidroins, reveal a composite nature of silk-specific units, allowing the recombinant production of individual and combined segments. In this report, a miniaturized spidroin gene, named VSO1 that contains repetitive motifs of MaSp1 has been synthesized and combined to form multimers of distinct lengths, which were heterologously expressed as elastin-like peptide (ELP) fusion proteins in tobacco. The elastic penetration moduli of layered proteins were analyzed for different spidroin-based biopolymers. Moreover, we present the first immunological analysis of synthetic spidroin-based biopolymers. Characterization of the binding behavior of the sera after immunization by competitive ELISA suggested that the humoral immune response is mainly directed against the fusion partner ELP. In addition, cytocompatibility studies with murine embryonic fibroblasts indicated that recombinant spidroin-based biopolymers, in solution or as coated proteins, are well tolerated. The results show that spidroin-based biopolymers can induce humoral immune responses that are dependent on the fusion partner and the overall protein structure. Furthermore, cytocompatibility assays gave no indication of spidroin-derived cytotoxicity, suggesting that recombinant produced biopolymers composed of spider silk-like repetitive elements are suitable for biomedical applications.

    The eighth in a series of oil price expectation studies took place on 18th March 1992 at the Prospects for Oil Prices conference held at the University of Surrey. Thirty-one participants returned a questionnaire designed to elicit 12 month ahead and 5 year ahead price expectations. Respondents were asked to indicate their view of the likely price of oil in certain broad price ranges. These were selected to cover the wide variation of prices experienced since the early 1970s. The results show the 12 month's ahead expectations all clustered in the range $10 to $25 per barrel and $16-$20 as the median predicted price. In comparison with the 1991 expectations, a much higher proportion of respondents (77.4 as compared to 50% in 1991) gave $16-20 as their expected price range, whilst fewer expected prices to rise (19% compared with 46% in 1991). The stability of the 12 month ahead price expectations is a remarkable feature of a period which has witnessed much tension in the Middle East and in the former Soviet Union. This stability extends to the 5 year ahead forecasts as well. Here the median expectation is for prices to rise to the $21-25 per barrel range in money of the day terms though there is evidence of a growing scepticism about the oil market's ability to sustain higher prices in the long run.

    Stress corrosion cracking occurs in the flow-restricted areas on the secondary side of steam generator tubes of Pressured Water Reactors (PWR), where water pollutants are likely to concentrate. Chemical analyses carried out during the shutdowns gave some insight into the chemical composition of these areas, which has evolved during these last years (i.e. less sodium as pollutants). It has been modeled in laboratory by tests in two different typical environments: the sodium hydroxide and the sulfate environments. These models satisfactorily describe the secondary side corrosion of steam generator tubes for old plant units. Furthermore, a third typical environment - the complex environment - which corresponds to an All Volatile Treatment (AVT) environment containing alumina, silica, phosphate and acetic acid has been recently studied. This particular environment satisfactorily reproduces the composition of the deposits observed on the surface of the steam generator tubes as well as the degradation of the tubes. A review of the recent laboratory results obtained by considering the complex environment are presented here. Several tests have been carried out in order to study initiation and propagation of secondary side corrosion cracking for some selected materials in such an environment. 600 Thermally Treated (TT) alloy reveals to be less sensitive to secondary side corrosion cracking than 600 Mill Annealed (MA) alloy. Finally, the influence of some related factors like stress, temperature and environmental factors are discussed. (authors)

    Full Text Available In terms of GDV prevention, a number of non-surgical measures are recommended. However, the only truly reliable method is gastropexy, most often as part of a surgical treatment of GDV. Gastropexy may be performed preventively either during laparotomy indicated for another reason than GDV, or newly laparoscopically, as independent preventive gastropexy. Preventive laparoscopic assisted gastropexy (PLAG was performed in 17 patients at the Department of Surgery and Orthopaedics of the Small Animal Clinic at the University of Veterinary and Pharmaceutical Sciences in Brno. Clinical results and complications of PLAG were evaluated 3-12 months after surgery. The most frequent clinical finding of PLAG was a skinfold at the site of gastropexy immediately after the surgery (n = 8; 47%, or still on day 12 after the surgery (n = 1; 6%. As for PLAG complications, in one case a seroma formation was found at the site of gastropexy (6%; in two patients iatrogenic perforation of the splenic capsule (12% occurred, which in one case gave reason to converting laparoscopy into laparotomy (6%. In none of the patients, death, gastropexy failure, GDV development, dehiscence, infection of or haemorrhage from the surgical wound were noted. Laparoscopic assisted gastropexy appears as a reliable and miniinvasive surgical method of GDV prevention and it may be recommended for high-risk breeds of dogs.

    This report describes the fiscal 1974 research result on glass system materials of plane collectors for solar cooling/heating. A barrel lens type collector was poorer in efficiency than conventional ones. A one-directional Fresnel lens type one was promising for improvement of solar radiation collection. The prototype In{sub 2}O{sub 3} selective transmission cover glass was prepared by vacuum deposition. Although selective characteristics including a solar transmissivity of 74% and an IR reflectance of 75-80% were obtained, further improvement of more than 10% is necessary. The evaluation results of some collectors are as follows. A vacuum type is poor because of its low efficiency and necessary vacuum sealing. A multi-layer type shows unsatisfactory performance at some temperatures. A glass honeycomb type is most likely because of its uppermost collection efficiency, however, development of production technology of heat-resistant honeycombs and its profitability remain to be solved. A deformed multi-layer type is practical because of its high efficiency, simple structure and low cost. Further improvement of the transmissivity and IR reflectance of cover glass by more than 10% is necessary. (NEDO)

    There has been a resurgence of syphilis diagnoses in Australia. We investigated whether our Treponema pallidum PCR test provides any additional diagnostic information over syphilis serology (chemiluminescence immunoassay [CMIA], Treponema pallidum particle agglutination [TPPA] assay, and the rapid plasma reagin [RPR] flocculation test). A retrospective audit of all T. pallidum PCR requests that came through our laboratory from January 2010 to June 2017 was conducted; data collected included age, gender, site of swab, and results from T. pallidum PCR, syphilis serology, and herpes simplex virus 1 (HSV-1) and HSV-2 PCRs. A total of 441 T. pallidum PCR tests were performed; on average, 3 T. pallidum PCRs per month were requested in 2011, and this rate increased to 17.2 requests per month in 2017. A total of 323 patients had both T. pallidum PCR and syphilis serology performed, with 67% of swabs taken from the genitals. T. pallidum PCR gave positive results for 61/323 (19%) patients; of these 61 patients, 59 (97%) also had positive syphilis serology results ( T. pallidum PCR sensitivity, 68%; specificity, 99%; positive predictive value, 97%; negative predictive value, 89%). Syphilis serology was positive for 91/323 patients (28%); of these 91 patients, 61 (66%) were also T. pallidum PCR positive (syphilis serology sensitivity, 97%; specificity, 88%; positive predictive value, 60%; negative predictive value, 99%). The Cohen's kappa value was 0.74, indicating substantial agreement between the two tests. Our results show that most patients with positive T. pallidum PCR results also had positive syphilis serology. Therefore, T. pallidum PCR adds little clinical value over serology for the diagnosis of syphilis in certain clinical settings. Copyright © 2018 American Society for Microbiology.

It is expected that some 60000-70000 family houses will be above the intervention level of 400 Bq/m 3 . A total of 130000 such houses have been examined so far, and 20000 of them were above the intervention level. Building owners can apply for governmental radon mitigation subsidy. Prior to remedial measures, radon diagnosis is carried out to objectify the radon concentrations, identify radon sources and prepare the radon mitigation design. Since a survey of the long-term effectiveness of remedial measures has shown that 25 % of them failed in some years, long-term after-mitigation test measurements are of importance. A Radon Bulletin and special leaflets are published periodically to improve public awareness of the radon issue. A quantitative survey gave evidence that the level of awareness among the Czech population is 75 %

    HbA1c is used in the diagnosis and monitoring of diabetes mellitus (DM). Interference from hemoglobin variants is a well-described phenomenon, particularly with HPLC-based methods. While immunoassays may generate more reliable HbA1c results in the presence of some variants, these methods are susceptible to negative interference from high concentrations of HbF. We report a case where an accurate HbA1c result could not be obtained by any available method due to the presence of a compound hemoglobinopathy. HbA1c was measured by HPLC, immunoassay, and capillary electrophoresis. Hemoglobinopathy investigation consisted of a CBC, hemoglobin fractionation by HPLC and electrophoresis, and molecular analysis. HbA1c analysis by HPLC and capillary electrophoresis gave no result. Analysis by immunoassay yielded HbA1c results of 5.9% (Siemens DCA 2000+) and 5.1% (Roche Integra), which were inconsistent with other markers of glycemic control. Hemoglobinopathy investigation showed HbC with the hereditary persistence of fetal hemoglobin-2 Ghana deletion. Reliable HbA1c results may be unobtainable in the presence of some hemoglobinopathies. HPLC and capillary electrophoresis alerted the laboratory to the presence of an unusual hemoglobinopathy. Immunoassays generated falsely low results without warning, which could lead to missed diagnoses and under treatment of patients with DM. Copyright © 2016 Elsevier B.V. All rights reserved.

  19. CFD optimization of a pellet burner

    Full Text Available Increased capacity of computers has made CFD technology attractive for the design of different apparatuses. Optimization of a pellet burner using CFD was investigated in this paper. To make the design tool work fast, an approach with only mixing of gases was simulated. Other important phenomena such as chemical reactions were omitted in order to speed up the design process. The original design of the burner gave unsatisfactory performance. The optimized design achieved from simulation was validated and the results show a significant improvement. The power output increased and the emission of unburned species decreased but could be further reduced. The contact time between combustion gases and secondary air was probably too short. An increased contact time in high temperature conditions would possibly improve the design further.

    be measured explicitly and are used as fixed parameters in the PARIO evaluation, the error of the clay fraction is determined by error propagation from the sand and silt fraction. Homogenization of the suspension by overhead shaking gave lower reproducibility and smaller silt fractions than vertical stirring. However, it turned out that vertical stirring must be performed with sufficient rigour to obtain a fully homogeneous initial distribution. Analysis of material sieved to < 2000 μm and to < 200 μm gave equal results, i.e., there was no hint towards dragging effects of large particles. Complete removal of the sand fraction, i.e. sieving to < 63 μm lead to less silt, probably due to a loss of fine material by the sieving process. The PSD's obtained with the PARIO corresponded very well with the results of the Pipette method.

    Linear chromosomes are atypical in bacteria and likely a secondary trait derived from ancestral circular molecules. Within the Rhizobiaceae family, whose genome contains at least two chromosomes, a particularity of Agrobacterium fabrum (formerly A. tumefaciens) secondary chromosome (chromid) is to be linear and hairpin-ended thanks to the TelA protelomerase. Linear topology and telA distributions within this bacterial family was screened by pulse field gel electrophoresis and PCR. In A. rubi, A. larrymoorei, Rhizobium skierniewicense, A. viscosum, Agrobacterium sp. NCPPB 1650, and every genomospecies of the biovar 1/A. tumefaciens species complex (including R. pusense, A. radiobacter, A. fabrum, R. nepotum plus seven other unnamed genomospecies), linear chromid topologies were retrieved concomitantly with telA presence, whereas the remote species A. vitis, Allorhizobium undicola, Rhizobium rhizogenes and Ensifer meliloti harbored a circular chromid as well as no telA gene. Moreover, the telA phylogeny is congruent with that of recA used as a marker gene of the Agrobacterium phylogeny. Collectively, these findings strongly suggest that single acquisition of telA by an ancestor was the founding event of a large and diverse clade characterized by the presence of a linear chromid. This clade, characterized by unusual genome architecture, appears to be a relevant candidate to serve as a basis for a possible redefinition of the controversial Agrobacterium genus. In this respect, investigating telA in sequenced genomes allows to both ascertain the place of concerned strains into Agrobacterium spp. and their actual assignation to species/genomospecies in this genus.

  2. How early studies on secreted and membrane protein quality control gave rise to the ER associated degradation (ERAD) pathway: the early history of ERAD.

    All newly synthesized proteins are subject to quality control check-points, which prevent aberrant polypeptides from harming the cell. For proteins that ultimately reside in the cytoplasm, components that also reside in the cytoplasm were known for many years to mediate quality control. Early biochemical and genetic data indicated that misfolded proteins were selected by molecular chaperones and then targeted to the proteasome (in eukaryotes) or to proteasome-like particles (in bacteria) for degradation. What was less clear was how secreted and integral membrane proteins, which in eukaryotes enter the endoplasmic reticulum (ER), were subject to quality control decisions. In this review, we highlight early studies that ultimately led to the discovery that secreted and integral membrane proteins also utilize several components that constitute the cytoplasmic quality control machinery. This component of the cellular quality control pathway is known as ER associated degradation, or ERAD.

    Active learning, including the promotion of student interactivity in lectures, has been found to improve student engagement and performance in university science classes. This letter describes the use of Pearson's Learning Catalytics to run regular, formatively assessed problem-solving sessions as part of the semiflipped redesign of an introductory level university bioscience course. Students found the problem-solving sessions more engaging than a traditional lecture, and felt that they were receiving better feedback on their progress in the course. Their participation in the problem-solving sessions was strongly associated with their performance in the course's summative assessments, making it possible to identify and assist probable poor performers early in the course. Other measures of student engagement with the course were not improved, and neither were their average exam grades when compared with their grades in a course which had not been redesigned. Possible reasons for this are discussed. © FEMS 2017. All rights reserved. For permissions, please e-mail: journals.permissions@oup.com.

    Approximately 7% of young school-aged children have specific language impairments. Many such children are now being educated in mainstream settings. However, there is a dearth of up-to-date and valid research that considers UK (student) teachers' attitudes towards such children. This study aimed to investigate trainee teachers' attitudes towards teaching children with speech and language impairments, to investigate the reported effects of those attitudes on participants' acceptance of teaching such children, and to consider any implications for speech and language therapy (SLT) services and inclusive education. Nineteen trainee teachers (PGCE students) from a university in the North West of England took part in semistructured group interviews. The data were transcribed and analysed qualitatively, and recurrent themes identified. A range of attitudes was expressed, and six major themes were identified from the data. Participants discussed concerns about the resources and knowledge they considered necessary to support fully children with specific language impairments. There was some differentiation of attitudes related to the types of disability that a child may have and the subject being taught. Much of the discussion was about disabilities in general rather than specific to speech and language impairments. Many of the participants reflected on their own previous experiences to inform their opinions. Although many of the participants expressed positive attitudes, some had concerns about workload and at least one was openly hostile to the idea of teaching children with disabilities within mainstream settings. The implications of these findings are discussed in relation to previous research, the quantitative data obtained in this project, SLT services and the increases in the inclusion of children with specific language impairments into mainstream educational settings.

    Pregnancies in spinal cord-injured (SCI) patients present unique clinical challenges. Because of the neurogenic bladder and the use of intermittent catheterization, chronic bacteriuria and recurrent urinary tract infection (UTI) is common. During pregnancy the prevalence of UTI increases dramatically. Recurrent UTI requires multiple courses of antibiotics and increases the risks of abortion, prematurity, and low birth weight. A weekly oral cyclic antibiotic (WOCA) program was recently described for the prevention of UTI in SCI patients. To test the impact of WOCA in six SCI pregnant women (four paraplegic, two tetraplegic). This was a prospective observational study. WOCA consists of the alternate administration of one of two antibiotics once per week. We observed a significant reduction of UTI (6 UTI/patient/year before pregnancy to 0.4 during pregnancy and under WOCA; pUTI prophylaxis in SCI pregnant women.

    Full Text Available The article aims to analyze the trajectory of Manuel Arruda da Câmara (1752-1810, a reference in Botany and Medicine in the late 18th century, highlighting his vision of Brazilian Nature. The most representative concepts of the Enlightenment, like the belief in the power of reason, the knowledge of nature, the ideas of happiness and progress were also evident in colonial Brazil. Natural History and its branches attracted the interest of scholars such as Manuel Arruda da Câmara, highlighting important studies about Botany and its relationship with other areas of knowledge like Medicine, Agriculture, and Chemistry. The impact of theories of inferiority and immaturity conferred to American Nature in the second half of the 18th century by European thinkers such as Buffon and De Pauw, was also critical in formulating this knowledge. These theories predicated upon the assertion of a close organic connection between living creatures and nature, in a deterministic way. Learned men sought to respond these statements making studies that refuted the negative characterization of American continent. Thus it was important emphasize the potential and virtues of local nature.

    2017-08-01

    Full Text Available This text examines the experiences of several women ethnologists / anthropologists in regard to women’s inheritance rights and the traditional practices used in contemporary context in Macedonia. Women’s inheritance rights and traditional norms, which, according to the ideal model, recommend that a woman cannot be an heir of immovable property, are among the main associations of patriarchy on the Balkans. The women interlocutors in this research consistently hold on to the thesis that the term “patriarchy” is inadequate for describing in general terms the status of women in the radically divided periods of the traditional past or the contemporary context. Therefore, this situation entails a great methodological challenge in the context of the research theme, when the experiences from the everyday life of the researchers seem to contradict their theses in regard to patriarchy.

Part I of this article reviewed special contributions of the world renowned scientist to the establishment of radiology as a new discipline in medicine. This paper deals with the use of Tesla currents in medicine. Tesla Currents in Medicine. Tesla's greatest impact on medicine is his invention of a transformer (Tesla coil) for producing high frequency and high voltage currents (Tesla currents). Tesla currents are used in diathermy, as they, while passing through the body, transform electrical energy into a therapeutic heat. In 1891, Tesla passed currents through his own body and was the first to experience their beneficial effects. He kept correspondence on electrotherapy with J. Dugan and S. H. Monell. In 1896, he used high frequency currents and designed an ozone generator for producing ozone, with powerful antiseptic and antibacterial properties. Tesla is famous for his extensive experiments with mechanical vibrations and resonance, examining their effects on the organ ism and pioneering their use for medical purposes. Tesla also designed an oscillator to relieve fatigue of the leg muscles. It is less known that Tesla's inventions (Tesla coil and wireless remote control) are widely used in modern medical equipment. Apart from this, wireless technology is nowadays widely applied in numerous diagnostic and therapeutic procedures. Nikola Tesla was the last Renais- sance figure of the modern era. Tesla bridged three centuries and two millennia by his inventions, and permanently indebted humankind by his epochal discoveries.

    The interest in Nikola Tesla, a scientist, physicist, engineer and inventor, is constantly growing. In the millennialong history of human civilization, it is almost impossible to find another person whose life and work has been under so much scrutiny of such a wide range of researchers, medical professionals included. Although Tesla was not primarily dedicated to biomedical research, his work significantly contributed to the development of radiology, and high frequency electrotherapy. This paper deals with the impact of Tesla's work on the development of a new medical branch - radiology. Nikola Tesla and the Discovery of X-ray radiation. Tesla pioneered the use of X-rays for medical purposes, practically laying the foundations of radiology. Namely, since 1887, Tesla periodically experimented with X-rays, at that time still unknown and unnamed, which he called "shadowgraphs". Moreover, at the end of 1894, lie conducted extensive research focusing on X-rays, but unfortunately it was inlerrupted after the fire burning down his laboratory in 1895. In 1896 and 1897, Tesla published ten papers on the biologic effects of X-ray radiation. All his studies on X-rays were experimental. During 1896 and 1897, Tesla continued improving X-ray devices. Apart from this, Tesla was the first to point out the harmful effects of exposure to X-ray radiation on human body. Nikola Tesla was a visionary genius of the future. Tesla's pioneer steps, made more than a century ago in the domain of radiology, are still being used today.

    Three iodine-125-digoxin radioimmunoassay kits (A Amersham Buchler; B Boehringer Mannheim; C Schwarz Mann/Becton Dickinson) were evaluated with respect to assay quality and comparability of the results. Intra- and interassay variances were calculated for the following types of samples: Three media (a pool serum; b artificial human serum; c buffer solution with albumin and globulin) containing pure digoxin, sera from a pharmacokinetic study, sera with different concentrations of proteins, a hemolytic serum and sera with digitoxin and metabolites of spironolactone. The intra-assay precision depended on the medium of the sample and was higher for samples with identical digoxin concentrations in an identical medium (e.g. CV for 2 μg/l in medium a for kit A: 4.3% for kit B: 7.0%; for kit C: 2.2%) than for samples with identical antigen concentrations in different media (CV for 2 μg/l in media a, b and c for kit A: 6.4%; for kit B: 9.1%; for kit C: 4.3%). The mean recovery in the range 0.5-4 μg/l depended on the kind of medium (a, b or c) and varied for kit A from 84.4% to 100.8%, for kit B from 112.0% to 119.6%, and for kit C from 98.0% to 104.5%. Decreasing serum protein concentrations to less than one half of the physiological concentration gave false negative results for kit A and fals positive results for kit C; for kit B this dependency was not be observed, but there was a decrease of reproducibility.

    Many of the disturbances resulting from dysregulations in the autonomous nervous system of children with cerebral palsy are rarely discussed in the doctor's praxis. Nevertheless, they are causes of trouble and worry for the parents. For this reason we started an inquiry into this matter. Questionnaires were sent to the parents of 452 C.P. patients. 374 were answered with sufficient care. The following factors were evaluated: sleep, bladder and bowel activity, temperature regulation, vomiting, sweating, blood circulation, growth. The C.P. children were compared to their own siblings especially to the next younger ones. The diagnoses were as follows: Spastic tetraplegia 197 patients. Spastic hemiplegia 44 patients, Athetosis 33 patients, Mixed cases of spasticity and athetosis 82 patients, Other 15 patients. The degrees of handicap in terms of motor development were: severe (unability to sit unsupported) 166 cases, moderate (unability to kneel or walk unsupported) 118 cases, mild (ability to kneel and/or walk unsupported) 87 cases. Summarized, the statements of the parents gave the following results: sleep disturbances: 169 cases (46%), constipation: 145 cases (39%), tendency towards temperature dysregulation: 112 cases (30%) , tendency towards increased vomiting: 91 cases (25%), sweating increased or decreased: 110 cases (30%), irregular and frequent voiding of bladder: 92 cases (25%), unstable regulation of blood circulation: 101 cases (27%), cold skin: 264 cases (71%), body-length deficit: 119 cases (32%), low-weight: 177 cases (48%), feet too small for age: 252 cases (68%). Results are related to diagnosis and severeness of handicap. In addition, it is discussed, whether there are relations between several of the investigated factors. The influence of the patients sex is discussed.

  20. Assessing incentive contracts for reducing residential electricity consumption: new experimental methods for new results

    International Nuclear Information System (INIS)

    Frachet, Laure

    2013-01-01

    Facing economic, political and environmental stakes, electricity providers are nowadays developing incentive tools, in order to reduce consumer's demand, particularly during peak demand periods. For residential customers, these tools can be tariffs (dynamic pricing of time-of-use tariffs), or informative devices or services (feedbacks on historical or real-time consumption, given on various media). They might go along with automation systems that can help cutting of some electric devices when needed. In order to evaluate the capacity of these settings among their customers, electricity utilities are developing quite a few studies, which are mainly field experiment often called pilots. During these pilots, demand response tools are implemented on a population sample. These long and expensive studies lid to quantitative and qualitative analysis. We have compiled about 40 of them and extract from this survey some generalizable teachings. We have shown what these results were and highlighted pilot programs' methodological limits. In order to propose a substitute to these heavy experimentations, we assessed the capacity or experimental economics. This relatively new discipline's objective is to evaluation the efficiency of institutions, like markets, but also to study what animate economic agents' behaviour, e.g. preferences, beliefs, cognitive biases, willingness to pay... We were also able to elaborate an experimental protocol dedicated to the evaluation of some demand response contracts' acceptability. The results collected during 14 experimental sessions gave us some innovative clues and insight on these contracts acceptability. But, beyond these results, we have demonstrated that even if experimental economics can't obviously be a substitute for field experiments, it can represent an interesting exploratory methodology. To sum up the experimental economics can take part of residential customers' behaviour understanding, performing

The primary objective of the study was to compare in patients with and without MS the rate of BP control defined as a systolic BP ≤140 mmHg and a diastolic BP ≤90 mmHg. Patients were prospectively included and the follow-up lasted 6 months. The study population consisted of 24,069 hypertensive patients (56% men; mean age 62 ± 11 years; 18% diabetics; mean BP at inclusion 162 ± 13/93 ± 9 mmHg. MS was found in 30.4% of the patients (n = 7322: 35.2% women and 20.1% men. Three therapeutic subgroups were constituted: Group A, previously untreated, received the combination therapy as initial treatment; Group B, previously treated but with unsatisfactory results and/or treatment intolerance, had its previous treatment switched to perindopril/indapamide; and Group C, previously treated, with good treatment tolerance but uncontrolled BP, received the study treatment in adjunction to the previous one. The normalization rate was 70.3% in group A, 68.4% in Group B, and 64.1% in Group C (p < 0.0001. The pre-existence of MS did not show any significant influence on these rates since BP lowering was –22.7 ± 13.7 (SBP and –12.0 ± 10.0 mmHg (DBP in patients without MS and –22.6 ± 13.3 (SBP and −12.1 ± 9.7 (DBP in those with MS.

Growth of the Hevea plants in this experimental planting was fair, but yield data obtained by means of the Morris-Mann test indicated that it was rather low. The unsatisfactory growth as well as the poor yield are attributed to the poor handling of the rubber planting rather than to an unfavorable effect of the environment.

  3. Keystone conference on environmental biotechnology. Summary -- Results of conference

    1995-12-31

    This symposium brought together a unique mix of scientists, engineers and policy makers to discuss the latest applications of biotechnology to in situ bioremediation and ex situ biodegradation of pollutants and industrial wastes. Several new topics were prominent in the discussions. Chief among these were issues related to environmentally acceptable endpoints, command and control versus incentive driven regulations, bioavailability of pollutants to microbial action, delivery of biodegrading organisms to pollutant plumes, value added production, and genetic probes for monitoring the status of soil consortia. These new issues gave a new perspective to the more traditional topics of the molecular genetics of microorganisms, marine bioremediation, bioprocessing of industrial and agricultural wastes, and engineered bioremediation systems which were featured.

    A particle accumulator ring (PAR) is used at the Advanced Photon Source (APS) to collect multiple linac bunches and compress them into a 0.3-ns (rms) single bunch for booster injection. A 9.77-MHz fundamental rf system and a 117.3-MHz harmonic rf system are employed for initial beam capture and bunch length compression. Satellite bunches with very low charge form due to rf phase drifts or beam loading change. These satellites, when injected into the booster and then into the storage ring (SR), cause bunch impurity at three buckets from the target bucket. Storage ring and booster bunch cleaning was tried but proved to be difficult due to the top-up mode of operation in the storage ring and tune drift in the booster synchrotron. Recently we implemented a PAR bunch-cleaning system with tune-modulated harmonic rf knockout. Preliminary tests gave a measured SR bunch purity of better than 10

    Determination of the form of the one-dimensional surface gravity wave spectrum in water of finite depth is important for many scientific and engineering applications. Spectral parameters of deep water and intermediate depth waves serve as input data for the design of all coastal structures and for the description of many coastal processes. Moreover, the wave spectra are given as an input for the response and seakeeping calculations of high speed vessels in extreme sea conditions and for reliable calculations of the amount of energy to be extracted by wave energy converters (WEC). Available data on finite depth spectral form is generally extrapolated from parametric forms applicable in deep water (e.g., JONSWAP) [Hasselmann et al., 1973; Mitsuyasu et al., 1980; Kahma, 1981; Donelan et al., 1992; Zakharov, 2005). The present paper gives a contribution in this field through the validation of the offshore energy spectra transfer from given spectral forms through the measurement of inshore wave heights and spectra. The wave spectra on deep water were recorded offshore Ponza by the Wave Measurement Network (Piscopia et al.,2002). The field regressions between the spectral parameters, fp and the nondimensional energy with the fetch length were evaluated for fetch-limited sea conditions. These regressions gave the values of the spectral parameters for the site of interest. The offshore wave spectra were transfered from the measurement station offshore Ponza to a site located offshore the Gulf of Salerno. The offshore local wave spectra so obtained were transfered on the coastline with the TMA model (Bouws et al., 1985). Finally the numerical results, in terms of significant wave heights, were compared with the wave data recorded by a meteo-oceanographic station owned by Naples Hydrographic Office on the coastline of Salerno in 9m depth. Some considerations about the wave energy to be potentially extracted by Wave Energy Converters were done and the results were discussed.

    A major goal in evolutionary biology is to understand the genetic basis of adaptive traits. In migratory birds, wing morphology is such a trait. Our previous work on the great reed warbler (Acrocephalus arundinaceus) shows that wing length is highly heritable and under sexually antagonistic selection. Moreover, a quantitative trait locus (QTL) mapping analysis detected a pronounced QTL for wing length on chromosome 2, suggesting that wing morphology is partly controlled by genes with large effects. Here, we re-evaluate the genetic basis of wing length in great reed warblers using a genomewide association study (GWAS) approach based on restriction site-associated DNA sequencing (RADseq) data. We use GWAS models that account for relatedness between individuals and include covariates (sex, age and tarsus length). The resulting association landscape was flat with no peaks on chromosome 2 or elsewhere, which is in line with expectations for polygenic traits. Analysis of the distribution of p-values did not reveal biases, and the inflation factor was low. Effect sizes were however not uniformly distributed on some chromosomes, and the Z chromosome had weaker associations than autosomes. The level of linkage disequilibrium (LD) in the population decayed to background levels within c. 1 kbp. There could be several reasons to why our QTL study and GWAS gave contrasting results including differences in how associations are modelled (cosegregation in pedigree vs. LD associations), how covariates are accounted for in the models, type of marker used (multi- vs. biallelic), difference in power or a combination of these. Our study highlights that the genetic architecture even of highly heritable traits is difficult to characterize in wild populations. © 2018 John Wiley & Sons Ltd.

    Moral case deliberation is increasingly becoming part of various Dutch healthcare organizations. Although some evaluation studies of moral case deliberation have been carried out, research into the results of moral case deliberation within aged care is scarce. How did participants evaluate moral case deliberation? What has moral case deliberation brought to them? What has moral case deliberation contributed to care practice? Should moral case deliberation be further implemented and, if so, how? Quantitative analysis of a questionnaire study among participants of moral case deliberation, both caregivers and team leaders. Qualitative analysis of written answers to open questions, interview study and focus group meetings among caregivers and team leaders. Caregivers and team leaders in a large organization for aged care in the Netherlands. A total of 61 moral case deliberation sessions, carried out on 16 care locations belonging to the organization, were evaluated and perceived results were assessed. Participants gave informed consent and anonymity was guaranteed. In the Netherlands, the law does not prescribe independent ethical review by an Institutional Review Board for this kind of research among healthcare professionals. Moral case deliberation was evaluated positively by the participants. Content and atmosphere of moral case deliberation received high scores, while organizational issues regarding the moral case deliberation sessions scored lower and merit further attention. Respondents indicated that moral case deliberation has the potential to contribute to care practice as relationships among team members improve, more openness is experienced and more understanding for different perspectives is fostered. If moral case deliberation is to be successfully implemented, top-down approaches should go hand in hand with bottom-up approaches. The relevance of moral case deliberation for care practice received wide acknowledgement from the respondents. It can contribute

    We report the results of a VAMAS (Versailles Project on Advanced Materials and Standards) interlaboratory study on the measurement of composition in organic depth profiling. Layered samples with known binary compositions of Irganox 1010 and either Irganox 1098 or Fmoc-pentafluoro-L-phenylalanine in each layer were manufactured in a single batch and distributed to more than 20 participating laboratories. The samples were analyzed using argon cluster ion sputtering and either X-ray Photoelectron Spectroscopy (XPS) or Time-of-Flight Secondary Ion Mass Spectrometry (ToF-SIMS) to generate depth profiles. Participants were asked to estimate the volume fractions in two of the layers and were provided with the compositions of all other layers. Participants using XPS provided volume fractions within 0.03 of the nominal values. Participants using ToF-SIMS either made no attempt, or used various methods that gave results ranging in error from 0.02 to over 0.10 in volume fraction, the latter representing a 50% relative error for a nominal volume fraction of 0.2. Error was predominantly caused by inadequacy in the ability to compensate for primary ion intensity variations and the matrix effect in SIMS. Matrix effects in these materials appear to be more pronounced as the number of atoms in both the primary analytical ion and the secondary ion increase. Using the participants’ data we show that organic SIMS matrix effects can be measured and are remarkably consistent between instruments. We provide recommendations for identifying and compensating for matrix effects. Finally we demonstrate, using a simple normalization method, that virtually all ToF-SIMS participants could have obtained estimates of volume fraction that were at least as accurate and consistent as XPS.
