    Asthma continues to be an important cause of morbidity and mortality in developing countries. But, its burden among adult populations in university campuses is not well described. Through a multistage cluster sampling of students and staff of the Obafemi Awolowo University, Ile-Ife, Nigeria, we obtained a representative sample, each for students and staff. We administered the European Community Respiratory Health Survey (ECRHS) screening questionnaire to all the respondents. A subgroup did a spirometry test and completed a detailed questionnaire. Asthma was considered "possible", if a respondent provided affirmative response to symptoms of "wheezing or whistling", "attack of shortness of breath", "diagnosed attack of asthma" in the last 12 months or "currently taking medicines for asthma". From population of 13,750 students and 1428 staff of the university, we systematically sampled 2750 (20%) students and all the staff. Amongst these, 2372 students and 455 staff completed the screening questionnaire. The mean age (SD) of the responders was 21.9 (3.2) and 46.1 (8.9) for students and staff and most of them were men; 58.6% and 65.9%, respectively. While an estimated 2.6% (95% CI: 1.7-3.5) of students had an asthma attack in the preceding 12 months, 14.5% (95% CI: 12.5-16.5) and 25.2% (95% CI: 22.8-27.7) reported shortness of breath and nocturnal cough, respectively. The staff population reported fewer symptoms. The proportion with "possible asthma" was 18.2% (95% CI: 16.0-20.4) for students and 8.0% (95% CI: 5.4-10.7) for staff. The prevalence of asthma is high among students and staff of Obafemi Awolowo University, Nigeria.

    Dating violence is a complex phenomenon, and researchers continue to examine a wide range of precursors and contributing factors. Evidence indicates that violent intimate partners may be more likely to have personality disorders and dependency and attachment problems compared with non-violent ones. The aim of the present study is to evaluate the interaction between the personality profiles, pattern of psychopathology, and dating violence among university students in Obafemi Awolowo University, Ile-Ife. The study utilized a cross-sectional survey design with a total of 400 students selected using a multistage sampling technique. They completed the Sociodemographic Data Schedule, the Conflict Tactic Scale (CTS), Eysenck Personality Questionnaire (EPQ), and the General Health Questionnaire (GHQ). Univariate analysis was used to determine the prevalence of dating violence, psychopathology, and personality traits, and these were expressed in percentages. Association at bivariate level was assessed using chi-square and at multivariate level using logistic regression and correlations as was appropriate depending on the type of variable. The age of the respondents ranged between 18 and 35 years (M = 21.44, SD = 2.99). The prevalence of dating violence in the previous 12 months was 34%, and the prevalence of psychopathology was 15%. In the logistic regression model constructed, it was found that the significant predictors of dating violence were the psychoticism and neuroticism personality traits, which were also found to be positive correlates of psychopathology. The magnitude of dating violence found in this study is comparable with those found in other countries of the world. This study found an association between dating violence and personality in the study population and also between certain personality traits and psychopathology. The personality profiles of students could affect their interpersonal relationships greatly, and this fact must feature in dating violence

    Full Text Available Background: Intussusception is one of the most common causes of intestinal obstruction in children. While the outcome has improved in the developed nations, the same cannot be said of the developing countries, more especially in the sub-Saharan region. This study aims to review our current experience in the management of childhood intussusception and factors affecting surgical outcome at the Obafemi Awolowo University Teaching Hospitals Complex Ile-Ife. Patients and Methods: This was a retrospective study of 78 patients treated for intussusception at paediatric surgical unit of Obafemi Awolowo University Teaching Hospitals Complex Ile-Ife between January 1993 and December 2011. The case notes of the patients were retrieved and the following information was recorded: Demographic characteristics, month of occurrence, clinical presentation, investigations, and management as well as the post-operative outcome. The patients were divided into two groups in terms of outcome. Results: There were 58 males and 20 females (M:F = 2.9-1. The age of most of the patients was between 3 months and 9 months with peak incidence at 6 months. Most patients 46 (58.9% were seen during the dry season of December to April. Only six patients (7.7% presented within 24 hours of onset of illness. More than half of the patients presented after 24 hours. Passage of red currant stool, vomiting, abdominal pain, fever, and abdominal distension, passage of watery stool, anal protrusion and palpable abdominal mass in various combinations were the clinical features. All the patients had surgical operations. The most common type of intussusception was ileo-colic type in 64 patients (82.1%. Intestinal resection rate was 41%. The overall mortality rate was 15.4%. Conclusion: There was a delay in presentation of children with intussusception with high post-operative mortality.

    The maternal mortality ratio (MMR) of Nigeria remains high. This retrospective study aims to suggest evidence-based strategies towards achieving the sustainable development goal target 3.1 at the Obafemi Awolowo University Teaching Hospital (OAUTHC), Nigeria by providing contemporary data on MMR between October 2012 and September 2015. There were 86 maternal deaths and 5243 live births over the triennium, with annual MMRs of 1744, 1622 and 1512/100,000 live births, respectively. Fifty-six (65.2%) were postpartum deaths, while 44 (51.2%) occurred within 12 hours of admission. Using the WHO ICD-10 system, the causes of mortality were pregnancy-related infections; 26 (30.2%), haemorrhage; 20 (23.3%), hypertension; 13 (15.2%) and pregnancies with abortive outcomes; 11 (12.7%). Financial constraints, misdiagnosis and delayed referrals constituted the predominant contributors. The MMR at OAUTHC, Nigeria in the last triennium of the MDG was 'Extremely High'. Improved aseptic techniques, blood transfusion services, antimicrobial sensitivity evaluation, Universal Health Coverage, training-retraining of skilled birth-attendants and effective referral systems are advocated. IMPACT STATEMENT What is already known on the subject of the paper: Nigeria now contributes the largest proportion (19%) of the burden of maternal mortality worldwide, despite constituting just 2% of the global population. Reversing this adverse trend during the sustainable development goal (SDG) period demands effective strategies, which can only be predicated on reliable data at the hospital, regional and national levels. This article provides the contemporary maternal mortality data of the Obafemi Awolowo University Teaching Hospitals Complex, Ile-Ife, Nigeria, during the last triennium of the Millennium Development Goal era. The findings from the study revealed that the average maternal mortality ratio (MMR) of the Hospital over the three years was 1640/100,000 live births, and that pregnancy

    The mean activity concentrations of the naturally occurring radionuclides ( 226 Ra, 228 Ra and 40 K) in three types of meat (goat meat, beef and pork) from stock animals as well as free-range and intensive poultry raised within the OAU environment of the Obafemi Awolowo University (OAU), Ile-Ife, were measured by means of a well-calibrated high-purity germanium detector. The specific activities of 226 Ra in the three types of meat ranged from 1.11 to 5.83 Bq kg -1 with a mean of 3.10±1.52 Bq kg -1 . 228 Ra was not detectable in both beef and pork but had a range of 1.53-1.63 Bq kg -1 with a mean of 1.58±0.30 Bq kg -1 in goat meat while 40 K recorded an average specific activity of 360.00±54.20 Bq kg -1 for the various samples of meat. The mean activity values of 226 Ra, 228 Ra and 40 K for the poultry were 2.59±0.48, 0.78±0.13 and 265.01±15.90 Bq kg -1 , respectively. The results obtained for the daily radionuclide intake of the various meat types showed that those of 226 Ra ranged from 0.4 to 8.1 mBq d -1 with a mean of 4.9±0.4 mBq d -1 . Since 228 Ra was not detectable in beef and pork its daily intake could not be estimated. However, a mean value of intake of 2.2±0.4 mBq d -1 was obtained for goat meat. The values of 40 K intake ranged from 150.0 to 672.7 mBq d -1 with an average of 455.5±19.0 mBq d -1 . The mean daily intakes of 226 Ra, 228 Ra and 40 K for the two types of poultry were 6.15±0.70, 1.9±0.3 and 633.4±38.0 mBq d -1 , respectively

    Full Text Available Background: This study was designed to investigate the mean lumbar foramina height and length in male cadaveric specimens in Ile-Ife. Aim and Objectives: Two hundred and fifty intervertebral foramina derived from twenty-five male cadaveric specimens were analyzed, were studied. They were obtained from the Department of Anatomy, Obafemi Awolowo University, Ile-Ife, Osun State in Southwestern Nigeria. The cadavers were positioned prone and a routine paraspinal approach was employed to gain exposure to the posterior spinal element following meticulous soft tissue dissection. An osteotomy of the iliac crest was performed to adequately expose the fifth lumbar (L1-S1 foramina.Parameters assessed were; the foramen height and the foraminal length. The measurement was performed three times on each side using vernier calipers. The variations of the different measurements in the cephalo-caudal direction were analyzed for statistical differences using the “One way ANOVA” with post hoc test. Results: The result showed a gradual increase of the foramina height were observed on both right and left side from L1-L2 to L3- L4 and from then on decreased progressively towards the L5-S1 level. No statistical difference was noted in the measurements derived (p<0.05. Conclusion: A good understanding of the lumbar intervertebral foraminal are essential in surgical planning of suitably sized cannulas necessary for less invasive spine surgeries as well as help in diagnosis of pathologies surrounding this important region following adequate clinical evaluation and measurements using imaging.

    Full Text Available A retrospective study of septicaemia was conducted in Ile-Ife metropolis with a view to determine its incidence and changes in the predominant aetiological agents. Six hundred and fifty (650 subjects, aged from one day to seventy years and above were examined. They all had clinical features suggestive of septicaemia and were on admission at the Obafemi Awolowo University hospital Complex, Ile-Ife, Nigeria. Their blood specimens were seeded into thioglycolate and glucose broths and incubated at 37 °C for 7 days. Subcultures were performed after 1, 2, 3, 4 and 7 days respectively. Growth (positivity in the broths was assessed using conventional diagnostic methods namely macroscopy (visualization, Gram filming (microscopy and culture. The bacterial isolates harvested were subjected to in-vitro antibiotic susceptibility tests using the disc diffusion method. Etiology was established in 204 out of 650 subjects indicating an incidence of 31.4%. This difference in prevalence among different age groups was statistically significant (P 0.01. Monomicrobial septicaemia had a higher prevalence (92.2% than polymicrobial septicaemia (7.8%. Staphylococcus aureus and Escherichia coli constituted 43.8%. Most of the offensive microbes were facultative anaerobes (91.7% while very few were strict aerobes (6.8% and strict anaerobes (1.5%. The isolated anaerobes were Peptostreptococcus sp. (0.5% and Bacteroides fragilis (1%. The in vitro susceptibility of the bacterial isolates to antibiotics indicated 76.4-95.6% sensitivity to vancomycin, zinnat, peflacin and fortum. However, they were 60 – 90% resistant to penicillin, ampicillin, tetracycline and septrin. This study confirmed the diverse nature of bacterial etiologies of septicaemia in the area; the need for the use of thioglycolate broths, first subcultures on or before 24 h instead of starting off for after 48 h of incubation, complementary application of macroscopy, Gram filming and culture including

    Full Text Available Background: Laparoscopy is not yet routinely employed in many Paediatric Surgical Units in Nigeria despite the advantages it offers. This study describes the preliminary experience with laparoscopic procedures in a single centre. Patients and Methods: A retrospective analysis of all children who had laparoscopic surgery between January 2009 and December 2013 at the Paediatric Surgical Unit of Obafemi Awolowo University Teaching Hospitals Complex Ile-Ife was carried out. Their sociodemographic, preoperative and intraoperative data along with postoperative records were subjected to descriptive analysis. Results: Eleven (44% diagnostic and 14 (56% therapeutic procedures were performed on 25 children whose age ranged from 5 months to 15 years (Median: 84 months, Mean: 103 ± 64.1 months, including eight (32% females and 17 (68% males. Indications included acute appendicitis in 12 (48%, intra-abdominal masses in six (24%, three (12% disorders of sexual differentiation, two (8% ventriculoperitoneal shunt malfunctions and impalpable undescended testes in two (8% children. The procedures lasted 15-90 minutes (Mean = 54 (±21.6 minutes. Conversion rate was 17% for two patients who had ruptured retrocaecal appendices. No intra operative complications were recorded while three (12% patients had superficial port site infections post-operatively. All diagnostic (11 and two therapeutic procedures were done as day case surgery. The mean duration of hospital stay was 3.1 (±3.3 days for those who had appendectomies. Conclusion: Laparoscopic surgery in children is safe and feasible in our hospital. We advocate increased use of laparoscopy in paediatric surgical practice in Nigeria and similar developing settings.

    The World Health Organization in 1994 recommended that dental education should be problem based, socially and culturally relevant, and community oriented. To explore the perceptions of Pre-phase II (pre-clinical II) dental students on three methods of teaching used during two academic sessions. All part IV dental students in two consecutive sessions undergoing pre phase II course in the Faculty of Dentistry, Obafemi Awolowo University, Ile-Ife were recruited into the study. Three different modes of teaching that is, Problem based learning (PBL), hybrid PBL and traditional teaching were used to teach the students. A twenty two itemed anonymous questionnaire on a five point Likert scale was administered to the students at the end of the course. Six perceived factors were extracted from the questionnaire using factor analysis. There was a statistically significant difference (p method compared to the other methods of teaching. The perceived factor "communication with peers" had the highest mean score for PBL in both sessions (4.57 ± 0.58 and 4.09 ± 0.93 respectively). However, PBL method was very helpful in all the six perceived factors while the students perceived that the traditional method of teaching was not helpful in "interaction with tutors" and "challenge to critical thinking". The findings showed that students preferred the PBL method to other forms of teaching. PBL enhanced the students' communication skill, was very useful as pedagogic tool and improved their critical thinking.

A retrospective study conducted at the Orthopaedic Department, Obafemi Awolowo University Teaching Hospital, Ile-Ife,Nigeria. Records of all operated cases of lower limb long bone diaphyseal fractures including those with failed fixations from August 2006-July 2011 were reviewed. Data retrieved included type of implant used, aetiology and characteristics of Implant failure. Data were analysed using SPSS version 16. Frequency distribution of the variables of interest was done. Difference in failure rate of intramedullary nail versus DCP was tested using chi-square. Statistical significance was inferred at pfractures and met inclusion criteria, of which 135 had intramedullary nail fixation and 86 had DCP. The rate of implant failure in intramedullary nail was 1.5% while it was 5.8% in patients with DCP (p=0.113; 0R=4.10; 95% CI=0.65- 43.77). Implant fracture was the commonest type of failure seen (100% versus 60%) and non union was the commonest cause of failure seen (50% versus 40%) in the intramedullary nailing and DCP groups respectively. The likelihood of a failed implant is higher in fixations done with DCP compared with intramedullary nail though the difference was not statistically significant. Commonest reason for failure in both groups was non-union. Findings from this study may guide surgeons in choice of implant in the management of long bone fractures.

  15. Organochlorine pesticide residues in dried cocoa beans obtained from cocoa stores at Ondo and Ile-Ife, Southwestern Nigeria

    Directory of Open Access Journals (Sweden)

    J.A.O. Oyekunle

    Full Text Available Levels of organochlorine pesticides (OCPs were determined in dried cocoa beans obtained from cocoa produce stores at Ondo and Ile-Ife, Southwestern Nigeria. Cocoa beans samples were sun dried to a constant weight, pulverized and soxhlet extracted with dichloromethane to obtain the OCPs. Qualitative identification and quantitative evaluation of the extracted OCPs after clean-up on silica gel were accomplished with the aid of a Gas Chromatography coupled with an Electron Capture Detector (GC-ECD. Levels of OCPs in cocoa beans from Ondo had a mean range of ND (p, p’-DDE to 82.17 ± 54.53 ng/g (p, p’-DDT were higher than the OCPs levels in cocoa beans from Ile-Ife with a mean range of 0.37 ± 0.63 ng/g (Endrin to 57.76 ± 81.48 ng/g (p, p’-DDT. The higher levels of OCPs detected in the cocoa beans from Ondo could be an indication of higher volume of OCPs application by cocoa farmers in Ondo and its environs since cocoa plantations were more concentrated than Ile-Ife environs. Levels of OCPs determined in the cocoa beans were within the Maximum Residue Limit (MRLs for OCPs set by the World Health Organization/Food and Agricultural Organization. The study established the presence of OCPs in an important crop of Nigeria. Hence, there is the need to keep monitoring ecotoxicological chemical substances in agricultural food products of Nigeria so as to take steps that ensure health safety of end users.

    2011-01-01

    Determination of total elemental composition along the horizontal distances of both sides of major and minor roads in Ile- Ife is important because of the agricultural practices in the neighborhoods of the study area. Soil samples (0-15 cm) obtained from varying horizontal distances from both sides of major and minor roads in Ile-Ife were determined by PIXE method. Results showed a regular trend for the marker elements and irregular trend for the non marker elements. We hope that our findings may influence policy planning ofland usage especially for agriculture.

    Method: 120 subjects who received ARV drugs at a federal government-designated ART site located within the Obafemi Awolowo University Teaching Hospital complex, (OAUTHC, Ile-Ife, and a community-based non-governmental organisation, Living Hope Care (LIHOC, Ilesa, from February to May 2006 were serially recruited and studied. Relevant data were collected using an interviewer-administered, patient medication adherence questionnaire. Focus group discussions were also held among the subjects to further elicit qualitative information on factors influencing adherence to ART. Results: The age of participants ranged from 21 to 65 years with a mean age of 40.2 + 10.3 years. Participants had been on ARV drugs for a period ranging between three and 60 months. The overall adherence rate in the study population was 44%. 66% of participants who accessed ARV drugs from LIHOC, Ilesa, had good adherence while only 14% of participants who accessed ARV drugs from OAUTHC, Ile-Ife, had good adherence. Participants with good adherence did not pay funds for the preliminary ARV eligibility investigations and they were also offered regular adherence counselling. These facilities were barely available in the group with poor adherence. Demographic factors such as age, gender and marital status did not seem to have any significant association with adherence level (p > 0.05. Conclusion: The level of adherence was high in a cohort of PLWHA accessing ARV drugs in Ilesa while it was low among PLWHA receiving ART in Ife. The most important reasons for this difference were lack of funds for investigations and poor psycho-social counselling.

  6. Follicle Stimulating Hormone and Anti-Müllerian Hormone among Fertile and Infertile Women in Ile-Ife, Nigeria: Is there A Difference?

    Directory of Open Access Journals (Sweden)

    Okunola Temitope

    2017-01-01

    Full Text Available Background Reduced ovarian reserve predicts poor ovarian response and poor suc- cess rates in infertile women who undergo assisted reproductive technology (ART. Ovarian reserve also decreases with age but the rate of decline varies from one woman to another. This study aims to detect differences in ovarian reserve as measured by basal serum follicle stimulating hormone (FSH and anti-Müllerian hormone (AMH between a matched cohort of fertile and infertile regularly menstruating women, 18-45 years of age. Materials and Methods This case-control study involved 64 fertile and 64 subfertile women matched by age at recruitment. Peripheral blood samples were taken from the women recruited from the Gynecological and Outpatient Clinics of Obafemi Awolowo University Teaching Hospital, Ile-Ife, Nigeria. Serum FSH and AMH were quantified using ELISA at the Metabolic Research Laboratory of LAUTECH Teaching Hospital, Ogbomoso, Nigeria. Results A significant difference existed in the mean FSH of fertile (6.97 ± 3.34 and infertile (13.34 ± 5.24, P=0.013 women. We observed a significant difference in AMH between fertile (2.71 ± 1.91 and infertile (1.60 ± 2.51, P=0.029 women. There was a negative correlation between FSH and AMH in both fertile (r=-0.311, P=0.01 and infertile (r=-0.374, P=0.002 women. Conclusion The difference in ovarian reserve observed in this study suggests that reduced ovarian reserve in regularly menstruating women may be associated with early ovarian ageing or subfertility.

    Measurements of direct solar radiation intensity, using an Angstrom compensation pyrheliometer carried out over three harmattan seasons (1985-1987) at Ile-Ife (7.29N, 4.34E) Nigeria, have been used to determine atmospheric turbidity based on five different models of turbidity, viz: Schuepp (B), Angstrom (β), Kastrov (C), Unsworth (τ a ) and Linke (T). The five parameters indicate high aerosol loading of the atmosphere during the period and high correlation is established between them: (0.919 ≤ τ ≤ 0.999). An inverse relationship has been noticed between horizontal visibility and atmospheric turbidity: (-0.80 ≤ τ ≤ -0.76). (author). 35 refs, 15 figs, 4 tabs

Objective: To evaluate indications, arrhythmic pattern of Holter ECG, and heart rate variability (HRV among patients with hypertensive heart disease (HHD with or without heart failure and type 2 diabetes mellitus (T2DM seen in our cardiac care unit. Methods: Seventy-nine patients (32 males and 47 females were studied consecutively over a year using Schiller type (MT-101 Holter ECG machine. Results: Out of the 79 patients, 17 (21.5% had HHD without heart failure, 33 (41.8% had HHD with hypertensive heart failure (HHF, while 29 (36.7% were T2DM patients. The mean (standard deviation ages of HHD without heart failure, HHF and T2DM patients were 59.65 (±14.38, 65.15 (±14.30, and 54.66 (±8.88 respectively. The commonest indication for Holter ECG was palpitation (38%, followed by syncope (20.3%. Premature ventricular contraction was the commonest arrhythmic pattern among the 79 patients, especially among HHF patients. The HRV, using standard deviation of all normal-normal intervals was significantly reduced in T2DM patients (81.03±26.33, confidence interval [CI] =71.02–91.05 compared to the HHD without heart failure (119.65±29.86, CI =104.30–135.00 and HHF (107.03±62.50, CI =84.00–129.19.

    Hydrogeoenvironmental studies were carried out at the sewage-disposal site of Obafemi Awolowo University campus, Ile-Ife, Nigeria. The objective of the survey was to determine the reliability of the electrical-resistivity method in mapping pollution plumes in a bedrock environment. Fifty stations were occupied with the ABEM SAS 300C Terrameter using the Wenner array. The electrical-resistivity data were interpreted by a computer-iteration technique. Water samples were collected at a depth of 5.0 m in 20 test pits and analyzed for quality. The concentrations of Cr, Cd, Pb, Zn, and Cu are moderately above the World Health Organization recommended guidelines. Plumes of contaminated water issuing from the sewage ponds were delineated. The geoelectric sections reveal four subsurface layers, with increasing depth, lateritic clay, clayey sand/sand, and weathered/fractured bedrock, and fresh bedrock. The deepest layers, 3 and 4, constitute the main aquifer, which has a thickness of 3.1-67.1 m. The distribution of the elements in the sewage effluent confirms a hydrological communication between the disposal ponds and groundwater. The groundwater is contaminated, as shown by sampling and the geophysical results. Thus, the results demonstrate the reliability of the direct-current electrical-resistivity geophysical method in sensing and mapping pollution plumes in a crystalline bedrock environment. Résumé.

    Full Text Available Bread loaves randomly sampled from nine outlets and bakeries within Ile-Ife were analysed to determine their safety levels for human consumption with respect to bromate and trace metal contents. Bromate determination was carried out via spectrophotometric method while trace metals in the digested bread samples were profiled using Flame Atomic Absorption Spectrophotometer. Bromate levels in the analyzed bread samples ranged from 2.051 ± 0.011 μg/g to 66.224 ± 0.014 μg/g while the trace metal levels were of the order: 0.03–0.10 μg/g Co = 0.03–0.10 μg/g Pb < 0.23–0.46 μg/g Cu < 2.23–6.63 μg/g Zn < 25.83–75.53 μg/g Mn. This study revealed that many bread bakers around Ile-Ife had not fully complied with the bromate-free rule stipulated by NAFDAC contrary to the “bromate free” inscribed on the labels of the bread. The bread samples contained both essential and toxic trace metals to levels that could threaten the health of consumers over prolonged regular consumption.

    Research into intimate partner violence in the Nigerian environment has been limited. The objective of this study was to determine, amongst a sample of women attending the Enuwa Primary Health Care Center, Ile-Ife, the association between intimate partner violence and anxiety/depression. A descriptive cross-sectional study was conducted amongst 373 women who attended the antenatal clinic and welfare units of a primary health centre in Ile-Ife using the Composite Abuse Scale, the Hospital Anxiety and Depression Scale and a socio-demographic scale as instruments. Slightly over a third (36.7 %) reported intimate partner violence within the past year, 5.6 % had anxiety and 15.5 % were depressed. Anxiety and depression in the respondents were significantly associated with intimate partner violence. Women were ten times more likely to report being depressed and 17 times more likely to report anxiety if they were in violent relationships. This research has shown that the magnitude of intimate partner violence within the study population is comparable to those found in the developing countries. There are significant associations between intimate partner violence, anxiety and depression amongst the study population and this fact undoubtedly has implications for the mental health of the Nigerian woman.

    Bats (Chiroptera) are one of the most diverse groups of mammals which carry out important ecological and agricultural functions that are beneficial to humans. However, they are increasingly recognized as natural vectors for a number of zoonotic pathogens and favourable hosts for zoonotic infections. Large populations of the Straw-Coloured Fruit Bat (Eidolon helvum) colonize the main campus of the Obafemi Awolowo University (OAU), Ile-Ife, Nigeria, but the public health implications of faecal contamination and pollution by these flying mammals is unknown. This study characterized S. aureus obtained from faecal samples of these migratory mammals with a view to determining the clonal types of the isolates, and to investigate the possibility of these flying animals as potential reservoir for zoonotic S. aureus infections. One hundred and seven (107) S. aureus isolates were recovered from 560 faecal samples in eleven roosting sites from January 2008 to February 2010. A large proportion of the isolates were susceptible to antibiotics, and molecular characterization of 70 isolates showed that 65 (92.9%) were assigned in coagulase type VI, while accessory gene typing classified 69 isolates into the following: type I (12; 17.1%), type II (3; 4.3%), type III (1; 1.4%) and type IV (53; 75.7%). On the whole, the isolates were grouped in five (A-E) main genotypes. Of the ten representative isolates selected for multilocus sequence typing (MLST), nine isolates were assigned with new sequence types: ST1725, ST1726, ST1727, ST2463-ST2467 and ST2470. Phylogenetic analysis provided evidence that S. aureus isolates in group C were closely related with ST1822 and associated clones identified in African monkeys, and group D isolates with ST75, ST883 and ST1223. The two groups exhibited remarkable genetic diversity compared to the major S. aureus clade. Antibiotic resistance in faecal S. aureus isolates of E. helvum is low and multiple unique S. aureus lineages co-existed with E. helvum

    Full Text Available In Ile-Ife, it is very common to see quite a lot of local people engaging in mud bricks moulding, concrete block making, mud house construction and the bricklaying profession in general. These have particular bearing on the economy and the political situation of the people involved as in the profession there is set of rules and regulations guiding the rate and procedure for carrying out any such moulding or construction work. Considering the importance of this, the present study investigated the thermal performance of some selected building materials in the ancient city of Ile-Ife in Nigeria. The work demonstrated how a building envelope responds to outdoor conditions through graphic illustrations. This was followed by constructing three physical building models, with model 1 constructed of mud bricks, model 2 constructed of concrete blocks and model 3 constructed of cast concrete. Each of the models was first roofed with galvanised Iron roofing sheets, later with aluminium roofing sheets and finally with asbestos roofing. Readings were taken by inserting TGP-4500 Data loggers into appropriate positions. The results showed that internal temperatures in the mud-brick and cast concrete buildings remained fairly stable despite external diurnal fluctuations. Humidity data collected also showed that fluctuations in external humidity levels do not affect humidity levels within the mud-brick and cast concrete structures significantly. On the other hand, the structure made of concrete blocks responded more to external fluctuations in temperature and humidity. Moreover, humidity levels in the cast concrete building were the least, followed by those in the mud-brick house; while the concrete block structure had the highest level of humidity. It was also discovered that aluminium roofing gave the highest internal temperature, followed by galvanised iron roofing and the least was seen with asbestos roofing. For external diurnal fluctuations, building model

    Full Text Available There has never been a single case report of any parasitic zoonosis in Ile-Ife while just a case of human Acanthocephalan infection in Nigeria is available.Fifty (house-rats Rattus rattus (Linnaeus, 1758 were caught in houses and raw food sellers' stalls in a market in Ile-Ife. A caught rat was removed from the cage and sacrificed by cervical jerking. A rat was weighed, measured, quickly following which thick and thin blood films on microscope slides were made from blood collected from the tail vein. The rat was examined for ectoparasites then dissected to check for endoparasites.Two ectoparasites (Xenopsylla cheopis and Laelaptid mite were recovered from 19 (38.0% of the rats. Five genera of helminthes (Moniliformis, Hymenolepis, Taenia, Trichuris and Trichinella were recovered from 29 (58.0% of the rats while seven genera of protozoa organisms (Amoeba, Dientamoeba, Entamoeba, Retortamonas, Trichomonas, Chilomastix and Trypanosoma were recovered from 48 (96.0% of them. There was no correlation (Spearman's correlation coefficient = -0.111 between the weight of the individual rat and the total number of alimentary canal acquired parasites.In relation to human health, implications of the rats serving as reservoir hosts for the different pathogens are highlighted. In view of the possibility of unexpected zoonosis arising from the parasites found in the peridomestic rats in this investigation and others not found, and in view of the difficulties that may be associated with diagnosing such ailment, especially by a clinician who trained locally, this report should be like raising awareness to these salient facts.

    Fertility pattern and reproductive behaviours affect infant death in Nigeria. Household food insecurity and poor care practices also place children at risk of morbidity and mortality. The objectives of this study were to assess the influence of family size, household food security status, and child care practices on the nutritional status of under-five children in Ile-Ife, Nigeria. The study employed a descriptive cross-sectional design. A semi-structured questionnaire was used to collect data from 423 mothers of under-five children and their children in the households selected through multistage sampling methods. Food-insecure households were five times more likely than secure households to have wasted children (crude OR = 5.707, 95 percent CI = 1.31-24.85). Children with less educated mothers were significantly more likely to be stunted. The prevalence of food insecurity among households in Ile-Ife was high. Households with food insecurity and less educated mothers were more likely to have malnourished children.

    Iron and steel smelting facilities generate large quantities of airborne particulate matter (PM) through their various activities and production processes. The resulting PM that contains a variety of heavy metals has potentially detrimental impacts on human health and the environment. This study was conducted to assess the potential health effects of the pollution from the heavy metals in the airborne PM sampled in the vicinity of secondary smelting operations in Ile-Ife, Nigeria. X-ray fluorescence (XRF) was used to determine the elemental concentration of Pb, Cr, Cd, Zn, Mn, As, Fe, Cu, and Ni in the size-segregated PM samples. Pollution Indices (PI) consisting of Contamination Factor (CF), Degree of Contamination (DC) and Pollution Index Load (PLI) and Target Hazard Quotient (THQ) were employed to assess the pollution risk associated with the heavy metals in the PM. CF, DC and PLI values were 332 and >1, respectively for the three sites, indicating deterioration of the ambient air quality in the vicinity of the smelter. The heavy metals in the airborne PM pose a severe health risk to people living in vicinity of the facility and to its workers. The diminished air quality with the associated health risks directly depends on the industrial emissions from steel production and control measures are recommended to mitigate the likely risks.

In addition, few population-based studies have been conducted recently in Nigeria on the prevalence and correlates of hypertension in both urban and rural communities. Therefore, we determined the prevalence of hypertension in adults in the three rural communities of Ipetumodu, Edunabon, and Moro, in South West Nigeria.Materials and methods: One thousand adults between 15 and 90 years of age were recruited into this cross-sectional study, over a 6-month period, using a multistage proportional stratified random sampling technique. Sociodemographic data and anthropometric variables were obtained, and resting blood pressure (BP was measured using an electronic sphygmomanometer. Diagnosis of hypertension was based on the JNC VII guidelines, the WHO/ISH 1999 guidelines, and the BP threshold of 160/95 mmHg.Results: Four hundred and eighty-six men (48.6% men and 514 women (51.4% participated in the study. Their mean age, weight, height, and body mass index were 32.3±14.7 years, 62±13 kg, 1.5±0.1 m, and 23.02 kg/m2, respectively. The prevalence of hypertension, based on the 140/90 mmHg definition, was 26.4% (Male: 27.3%; Female: 25.4%. The prevalence of hypertension, based on the 160/95 mmHg definition, was 11.8% (Male: 13.5%; Female: 10.1%.

    Full Text Available Aim: The objective of this study was to provide information on the level of utilization and satisfaction of residential university students with the dental services provided by the dental clinic of a teaching hospital. Volunteers and Material: A stratified sampling technique was used to recruit volunteers from the outpatient clinic of the Obafemi Awolowo University Teaching Hospital Complex, Ile-Ife, Nigeria. Information was collected by a self-administered questionnaire composed of questions that measure the level of utilization and satisfaction with the dental services provided. Questionnaires were provided to 650 randomly chosen students residing in the University hostels. There were 39 refusals, and 6 incomplete questionnaires were discarded. This left a sample size of 605 volunteers. Results: Forty seven students (7.8% indicated that they visited the dental hospital within the last 12 months. Males and females utilized the dental services equally, and utilization increased with age and the number of years spent on campus. Anticipation of painful dental treatment, high dental charges, long waiting times and being too busy for a dental visit were cited as the most important impediments to seeking dental treatment. Females expressed greater satisfaction with the services. Conclusion: Dental service utilization among the students was found to be low. Oral health awareness campaigns, improving the quality of the services, and shortening the waiting time are expected to increase service utilization and satisfaction.

    This study examined male adolescents' self-report of rape of adolescent girls and the socio-demographic variables that correlated with self-report of rape. Descriptive-correlational design was used and the study was conducted in five public senior secondary schools in Ile-Ife, Nigeria. Three hundred and thirty-eight male adolescents participated in the study. A structured questionnaire was used to collect data. Findings from the study revealed the mean age of the adolescent males to be 16 years, with the majority (73%) of them in the middle adolescent stage. Six percent of the adolescent males reported they had raped an adolescent girl in the past. Among the boys who reported rape, 55% reported they had raped their sexual partners, and 55% reported they had perpetrated gang rape. Smoking (p = .0001), alcohol consumption (p = .001), and birth order (p = .006) predicted self-report of rape. The coefficient of birth order showed that odds of self-report of rape by first-born male increases by 6 times compared with other children. Study findings also provided evidence that adolescent males are moving from lone rape to gang rape in intimate partner relationships. Male adolescents are important group to target in rape prevention programs. © The Author(s) 2014.

    Improper management of hospital waste has been reported to be responsible for several acute outbreaks like the severe acute respiratory syndrome (SARS). In spite of these challenges, hospital wastes are sometimes not properly handled in Nigeria. To date, there has not been an adequate study on the effect and fate of burnt hospital waste on agricultural soil. The effect of burnt hospital wastes on the agricultural soil was conducted on soils sampled around farm settlement near Obafemi Awolowo University Teaching Hospital Complex, Ile-Ife, South West Nigeria. PIXE technique was employed with a 1.7 MV 5SDH Tandem Pelletron accelerator available at Centre for Energy Research and Development O.A.U Ile-Ife, Nigeria. Eleven elements- Si, Cl, K, Ca, Ti, V, Cr, Mn, Fe, Zr and Pb were detected and their concentrations and enrichment factors determined. The presence of Pb and Cl at the elevated concentrations range of (77.8 ± 3.5 - 279.6 ± 97.6 and 102.2 ± 37.4 -167.2±17.43) ppm respectively in this study, is of serious health concern because of the agricultural practices in the neighborhoods of the study sites. There is a need for proper handling of hospital and other related hazardous wastes because of the possibility of such posing serious environmental pollution problems.

    In order to realize Nigeria's aspiration to harness nuclear science and technology for socio-economic development of the society, the federal government of Nigeria charged the Nigeria Atomic Energy Commission (NAEC) with the responsibility of promotion and development of peaceful uses of nuclear energy in all its ramifications. In realization of this laudable objective, two University-based nuclear research centres at Ile-Ife (i.e. Centre for Energy Research and Development, CERD, Obafemi Awolowo University, Ile-Ife) and Zaria (i.e. Centre for Energy Research and Training, CERT, Ahmadu Bello University, Zaria) under the supervision of NAEC are already running R and D programmes in nuclear science and technology for over three decades. A third centre, also under the supervision of the Commission in Abuja namely the Nuclear Technology Centre (NTC) located within the Sheda Science and Technology Complex (SHESTCO) was established in 1991 and operates a Gamma Irradiation Faci lity (GIF). Furthermore, NAEC has instituted a number of programmes including a road map aimed at the introduction of nuclear option into the energy mix of the country with projected targets of 1000MWe and 4000MWe by 2017 and 2027 respectively. However, with the number of nuclear scientists, engineers and technicians required to run a 1000MWe power plant put at 1000, there is the need to grow human capital for the industry in Nigeria. In this presentation, exciting opportunities in nuclear science for young graduates are enumerated. The importance of nuclear science and technology education vis-a-vis national economy and security for improved living standard is discussed. Specific workforce issues and sample career choices in medical science, the environment and energy applications are highlighted. Progress made so far by NAEC in the area of human resources development and capacity building is presented.

    Full Text Available Background: Hirschsprung′s disease (HD is a common cause of intestinal obstruction in children. Definitive treatments consist of excision of the aganglionic segment and anastomosing the normal colon to the anal remnant. The outcome of this approach in Nigerian children is not known. The aim of this study was to analyze the short to mid-term outcome of children who have undergone the Swenson Procedure (SPT as a treatment of HD over a period of 10 years. Patients and Methods: The clinical data of biopsy-proven cases of HD managed at the Obafemi Awolowo University Teaching Hospital, Ile-Ife, Nigeria, between 1998 and 2007 were reviewed. Results: There were 33 children 28 were males and five were females (M 5.6: F = 1. The median age at presentation was eight months (range three days to 11 years. Eighteen (54.5% patients had primary pull-through without colostomy while 15 (45.5% patients had a two-staged operation. The operation was carried out at a median age of 14 months with a range of seven weeks to 11 years, four months. Twenty-one (64% of the patients were older than one year at the time of surgery. The level of aganglionosis was in the recto-sigmoid area in 30 (91% patients. The commonest post-SPT complication was intestinal obstruction from adhesions. Bowel opening varied from once daily to eight times daily, median thrice daily. Conclusion: The Swenson′s Procedure is an effective procedure in the treatment of HD in children in Ile Ife, Nigeria.

    The upsurge in the demand for bottled water has prompted the interest of many manufacturers in the production of bottled water and very many water bottling companies are therefore involved in its production. These range from large scale multinational companies to medium scale business enterprises, institutional and government business investment companies as well as small scale entrepreneurs. There is however little information on the comparative quality of bottled water brands produced by different classes of water bottling companies in Nigeria. This study was undertaken to determine the bacteriological quality of brands of bottled water available to consumers in Ile-Ife. Forty-three samples of bottled water comprising of three batches each of thirteen bottled water brands and two batches of two brands were purchased and analyzed for total bacterial count, presence of coliform and the presence of other bacterial indicators of drinking water quality. Only 67.4% of the water samples representing the products of 10 companies or 66.7% of the brands had heterotrophic counts within the acceptable limits. Coliforms present in 100 ml of water were detected in 26.7% of the bottled water brands. Other indicator organisms detected included Staphylococci isolated from 27.9% of the samples (33.3% of the brands) and specifically Staphylococcus aureus found in four brands constituting 14% of the samples. Pseudomonas strains were consistently detected in consecutive batches of three brands of the water samples. Bottled water samples produced by the large scale multinational producers were of acceptable bacteriological quality unlike those produced by most small companies. There is need for a greater control of water bottling processes carried out by commercial bottled water producers in Nigeria.

    Full Text Available It is habitual for graduating students of the Obafemi Awolowo University, Ile-Ife, Nigeria, to roll out the drums the very day they finish writing their final examination. Characteristic of such a ritualistic exercise, among other things, are the brand names the students coin for themselves from their original names. This study focuses on the creative rewriting of the names on such an occasion and examines the linguistic habits exhibited therein. It analyses the phonological/graphematic features that mark the rewritng of the names and discusses the sociolinguistic implications for the phenomena of social identity construction and language contact situation. Data for the study was sourced mainly through participant-observation technique with a supplemment of an oral interview conducted for some of the subjects between year 2007 and 2009. The data was selected through a purposive random sampling technique which yielded fifty names that were considered representative of the respelling conventions. The paper employs mainly Hempenstall's (2003 Phonological Sensitivity Skills to analyse the linguistic practices in the reconfigured names and then applies Tajfel's and Turner's (1979 Social Identity Theory to explain how it is that people develop a sense of membership and belonging in particular groups. The article reveals that the deviant orthographic conventions are a major fallout of youth culture with great influence from computer-mediated communication. It also shows that their linguistic experimentation foray in the discourse greatly undermines the orthographic system of the indigenous language (Yoruba and the cultural values embedded in the original names.

    Full Text Available The phytochemical screening of Hyophila involuta collected from the Biological Garden of the Obafemi Awolowo University, Ile-Ife, Nigeria, was carried out to investigate the presence or absence of some secondary metabolites and its antibiotic potentials, using different extracts (with acetone and ethanol on selected organisms. The extracts obtained were screened for the presence of secondary metabolites like alkaloids, anthraquinones, cardiac glycosides, flavonoids, phlobatanins, saponins, steroids, tannins, triterpenes and xanthoproteins. Antimicrobial activity of the extracts was carried out on Escherichia coli, Staphylococcus aureus, Aspergillus flavus and Candida albicans. Only acetone extract tested positive for the presence of flavonoids, while alkaloids and cardiac glycosides were detected present in both the acetone and ethanolic extracts. Flavonoids were detected present only in the acetone extract. Saponins were detected present only in the ethanolic extract. The extracts (acetone and ethanolic showed significant activity on Staphylococcus aureus and Aspergillus flavus. The results obtained from this study indicated that H. involuta has medicinally important compounds, having therapeutic potential from which effective antimicrobial medicine can be sourced.

    Full Text Available Objectives: The aim of this study is to evaluate the success rate and complications of mandibular reconstruction with nonvascularized bone graft in Ile-Ife, Nigeria. Patients and Methods: A total of 25 patients who underwent reconstruction of mandibular discontinuity defects between January 2003 and February 2012, at the Obafemi Awolowo University Teaching Hospitals Complex, Ile-Ife constituted the study sample. Relevant information was retrieved from the patients′ records. This information include patients′ demographics (age and sex as well as the type of mandibular defect, cause of the defect, type of mandibular resection done, source of the bone graft used, and the method of graft immobilization. Morbidity associated with the graft procedures were assessed by retrieving information on graft failures, length of hospital stay following surgery, rehabilitation device used and associated graft donor and recipient site complications. Result: There were 12 males and 13 females with a male:female ratio was 1:1.1. The age of the patients ranged from 13 to 73 years with a mean age for males 32.7 ± standard deviation (SD 12.9 and for females 35.0 ± SD 17.1. Jaw defect was caused by resection for tumours and other jaw pathologies in 92% of cases. Complete symphyseal involvement defect was the most common defect recorded 11 (44%. Reconstruction with nonvascularized rib graft accounted for 68% of cases while iliac crest graft was used in 32% of the patients. Successful take of the grafts was recorded in 22 patients while three cases failed. Wound dehiscence (two patients and postoperative wound infection (eight patients were the most common complications recorded. Conclusion: The use of nonvascularized graft is still relevant in the reconstruction of large mandibular defects caused by surgical ablation of benign conditions in Nigerians.

    An investigation of the proximate composition and antioxidant profile of pumpkin seeds obtained from different levels of NPK 15 : 15 : 15 compound fertilizer application at the Obafemi Awolowo University, Ile-Ife, Nigeria was carried out. Pumpkin seeds were grown in 2010 for two cropping seasons (May to August and August to November), and the following fertilizer rates were applied: 0, 50, 100, 150, 200, and 250 kg/ha. Standard analytical methods were used to determine protein, crude fibre, ash, fat, carbohydrate, antioxidant activities, phenol, flavonoid, proanthocyanidin, and anthocyanin. The highest concentrations of the proximate and antioxidants analysed were found from the seeds of control and those treated with lower NPK rates. The mean protein, ash, crude fibre, and carbohydrate values of pumpkin seeds at zero to 100 kg NPK/ha were 27%, 1.56%, 0.56%, and 11.7% respectively. At these same levels of fertilizer, pumpkin seed oil yield was 59%. Antioxidant activities ranged from 89.9 to 90.4% while total phenol was 47 mg/100 g. Except for carbohydrate, the % concentration of nutrients and antioxidants in pumpkin seeds was significantly (P = 0.05) depressed with fertilizer rates above 100 g/ha.

    This study assessed awareness and availability of assistive facilities in a Nigerian public university. Study was conducted in Obafemi Awolowo University (OAU), Ile Ife Nigeria using a mixed methods approach. Fifty two students with disability (SWD) were interviewed with a semistructured, self-administered questionnaire. A checklist was used to assess assistive facilities on campus while in-depth interviews (IDI) were conducted with university officials, to assess their perspectives about the availability and use of assistive facilities in the university. Almost three-thirds (57.7%) of SWD were male while more than two-thirds were aged between 21 and 30 years. About seven in 10 (71.1%) respondents, had mobility impairment, while two-fifth had visual impairment (40.8%) and a few had hearing impairment. Only the university's administrative building had a functioning elevator. Slightly more than half (54.5%) of the lecture theatres have public address systems, while only two have special entrances and exits with ramps for SWD. Almost all respondents were unaware of facilities that aid learning (96.2%) and facilities for library use (90.4%). University officials were aware of assistive facilities for SWD but do not know the actual number of SWD. Assistive facilities for SWD on campus are limited. More assistive facilities need to be provided alongside increased awareness about these facilities and a disability register should be open for students on campus. Assistive facilities to aid learning and make SWD more comfortable are required. Implications for Rehabilitation Universities should have an official policy on students with disabilities and implement it, such a policy should address special considerations for disabled students, such as having an updated register for students with disability, having examination questions in large fonts for students with visual disabilities, giving them extra time for examinations and providing special counselling services for

    The Integrated Field Exercise (IFE14) was conducted from November 3, 2014 through December 9, 2014 in Jordan. This was an exercise to test the capabilities for On-Site Inspection (OSI) as part of the Comprehensive Nuclear-Test-Ban Treaty. One important OSI technology is the measurement of noble gasses that are produced within a nuclear explosion. To support IFE14, radioxenon samples and radioargon samples were created at The University of Texas at Austin TRIGA reactor facility. The goal was to produce a mixed sample containing 131m Xe, 133 Xe, and 37 Ar in activity ratios consistent with the nuclear explosion scenario defined for the exercise. (author)

    The Target Systems session of the Workshop on NIF Experiments for IFE developed a list of critical issues for inertial fusion energy (IFE) target systems, and considered the potential of the National Ignition Facility (NIF) to help in the resolution of these issues and in the development of IFE target systems. This paper describes the IFE Target System issues, categorized into target fabrication issues and target transport issues, describes potential NIF IFE target systems experiments, considers the impact of these experiments on the NIF and discusses the development required before these experiments could be done. Most target systems issues must be resolved by development in the laboratory, not in the NIF, and some must be resolved before the NIF can be successful. However, experiments done in the NIF could play a valuable role in developing target systems for IFE. These experiments should have modest impact on the basic design of the NIF, but could require several hundred dedicated, high yield shots

    Full Text Available Litterfall, precipitation and nutrient fluxes were investigated in a 0.25 ha plot of a secondary lowland rain forest in Ile-Ife, Nigeria, for a period of one year. The study determined the magnitude of nutrient fluxes through (litterfall, incident rainfall, throughfall and stemflow and evaluated the relative importance of these components as pathways of nutrient transport to the soil of this forest. There was a significant monthly variation in litterfall and the highest values of the standing crop of litter occurred from November to March. The concentration of elements in both throughfall and stemflow were higher than those of incidence rainfall. Greater quantities of calcium, magnesium, iron, zinc, copper and nitrogen were deposited annually from the forest floor while greater quantities of mercury, potassium, sodium, phosphorus, lead and sulphur were deposited via precipitation. There was net leaching of all elements from the canopy as precipitation pass through it with the exception of copper, hydrogen ions and lead, which were retained in the canopy. The finding of this study shows that litterfall is the major pathway for the cycling of calcium, magnesium, nitrogen and all micronutrients investigated. Net precipitation is the major pathway for the cycling of potassium, phosphorus, sulphur and trace toxic metals (mercury and lead in the forest.Produção de serapilheira, precipitação e o fluxo de nutrientes foram investigados em uma parcela de 0,25 ha de uma floresta pluvial secundária de terras baixas em Ile-Ife, Nigéria, por um período de um ano.

    The study of dental anomalies is important because it generates information that is important for both the anthropological and clinical management of patients. The objective of this study is to determine the prevalence and pattern of presentation of dental hard-tissue developmental anomalies in the mix dentition of children residing in Ile-Ife, a suburban region of Nigeria. Information on age, sex and socioeconomic status was collected from 1,036 children aged four months to 12 years through a household survey. Clinical examination was conducted to assess the presence of dental anomalies. Associations between age, sex, socioeconomic status, prevalence, and pattern of presentation of the developmental hard-tissue dental anomalies were determined. Two hundred and seventy six (26.6%) children had dental anomalies. Of these, 23.8% had one anomaly, 2.5% had two anomalies, and 0.3% had more than two anomalies. Of the children with anomalies, 49.3%were male, 50.7%were female, and 47.8%, 28.6% and 23.6% were children from low, middle and high socioeconomic classes, respectively. More anomalies were seen in permanent than primary dentition. Anomalies of tooth structure were most prevalent (16.1%); anomalies which affect tooth number were least prevalent (1.3%). Dens evaginatus, peg-shaped lateral, macrodontia, and talon cusp were more prevalent in the permanent dentition, and dens evaginatus peg-shaped lateral and macrodontia were more prevalent in the maxilla. There were significantly more macrodontia anomalies in males and in children of high socioeconomic status. This large survey of dental hard-tissue anomalies found in the primary dentition and mixed dentition of children in Nigeria provides anthropological and clinical data that may aid the detection and management of dental problems of children in Nigeria.

    Full Text Available Rainfed agriculture has a high yield potential if rainfall and land resources are effectively used. In this study, conventional (NC and six in-situ water conservation practices were used to cultivate Soybean in 2011 and 2012 in Ile-Ife, Nigeria. The conservation practices are: Tied ridge (TR, Soil bund (BD, Mulch (ML, Mulch plus Soil bund (MLBD, Tied ridge plus Mulch (TRML, Tied ridge plus Soil bund (TRBD. The practices were arranged in Randomised Complete Block Design with four replicates. Seasonal rainfall was 539 and 761 mm in 2011 and 2012, respectively. Seasonal soil water storage (SWS ranged from 485 mm for NC to 517 mm for TRML in the two seasons. ML increased the SWS in the upper 30 cm of the soil by 17% while TR increased the soil water content in the lower 30–60 cm by 22% compared with NC. ML reduced soil temperature in the upper 30 cm between 2.2 and 2.9 oC compared with NC, TR and TRML. Seasonal crop evapotranspiration ranged between 432 mm for NC and 481 mm for BD in the seasons. Grain yield increased by 41.7% and 44.3% for BD and MLBD, respectively compared with NC. Water conservation practices increased water productivity for grain yield by 14.0–41.8% compared with NC. Similarly, it increased average seasonal transpiration efficiency by 15.3–32.5% compared with NC. These findings demonstrate that when there are fluctuations in rainfall, in-situ water conservation practices improve SWS, land, and water productivity and transpiration efficiency of Soybeans.

    Full Text Available The aims of this study were to convert the starches from iles-iles tubers (Amorphophalus campanulatus and sorghum grains (Sorghum bicolor L into bioethanol as an alternative energy. Both of these agricultural products contains a high content starches and they do not use as the major foods in Indonesia. To find out the maximum ethanol concentration and yield, both the raw materials were converted to ethanol on various process variables including the concentration of flour substrate solution (100-300 g/L, β-amylase enzyme concentration (0.8 - 6.4 ml/kg of flour , the  concentration of dry yeast S. cerevisiae (2-15 g, and fermentation time (72-168 hours. The results showed that at the flour substrate concentration of 250 g/L produced the maximum ethanol contents of 100.29 g/L and 95.11 g/L   for iles-iles and sorghum, respectively. Effect of β-amylase enzyme in the saccharification process showed that at concentration  of 3.2 ml/kg  the maximum reducing sugar content of 204.94 g/L and 193.15 g/L  for iles-iles and sorghum substrate, respectively were generated therefore it was corresponding to the maximum ethanol production. The concentration effect of dry yeast S. cerevisiae in the fermentation stage for the iles-iles and sorghum substrate revealed that the maximum ethanol obtained at 5 g yeast activated in 100 ml medium starter resulted the highest ethanol content 100.29 g/L 95.11 g/L for iles-iles and sorghum substrate, respectively. To determine the effect of fermentation time on ethanol yield from iles-iles and sorghum substrate, the fermentation process were performed at 3, 5, and 7 days. The maximum ethanol fermentation was obtained at 5 days fermentation. The ethanol yield is calculated by weight of ethanol is formed (g divided by the weight of flour (g. Based on the experiment results, conducted, generally the highest ethanol yield of iles-iles was higher than that of sorghum flour. The highest yield (g/g iles-iles and sorghum

    Mokobia, C E; Anomohanran, O

    2005-01-01

    Gamma irradiation has been found to be very useful both for sterilisation in medicine and the preservation of food and cereals in nutrition and agriculture. This investigation was carried out to determine the effect of gamma irradiation on the subsequent germination and growth of irradiated seeds. Thirty seeds each of maize, okra and groundnut were irradiated to varying doses of 150, 300, 500, 700, 900, 1000 Gy using the 60 Co gamma cell irradiator facility at the Centre for Energy Research and Development, Obafemi Awolowo University, Ile-Ife. These, as well as the controls (unirradiated seeds), were planted on the same day in an already prepared area of farmland during the rainy season to ensure a constant moisture flow. The times of germination and subsequent growth were monitored. Results show that maize, okra and groundnut seeds needed for planting can be safely stored using gamma irradiation. However, the study reveals that the number of germinated seeds and the growth rate for the crops decrease with increase in the radiation dose the seeds were exposed to. Third-degree polynomial equations were derived which describe the percentage germination of the crops at various levels of exposure. A chart of percentage germination of seeds versus exposure dose is also presented as a quick guide to farmers, policy makers and agricultural institutions. (note)

    Gamma irradiation has been found to be very useful both for sterilisation in medicine and the preservation of food and cereals in nutrition and agriculture. This investigation was carried out to determine the effect of gamma irradiation on the subsequent germination and growth of irradiated seeds. Thirty seeds each of maize, okra and groundnut were irradiated to varying doses of 150, 300, 500, 700, 900, 1000 Gy using the {sup 60}Co gamma cell irradiator facility at the Centre for Energy Research and Development, Obafemi Awolowo University, Ile-Ife. These, as well as the controls (unirradiated seeds), were planted on the same day in an already prepared area of farmland during the rainy season to ensure a constant moisture flow. The times of germination and subsequent growth were monitored. Results show that maize, okra and groundnut seeds needed for planting can be safely stored using gamma irradiation.

    Z-pinch driven IFE (Z-IFE) requires the design of a repetitive target insertion system that allows coupling of the pulsed power to the target with adequate standoff, and a chamber that can withstand blast and radiation effects from large yield targets. The present strategy for Z-IFE is to use high yield targets ({approx}2-3 GJ/shot), low repetition rate per chamber ({approx}0.1 Hz), and 10 chambers per power plant. In this study, we propose an alternative power plant configuration that uses very high yield targets (20 GJ/shot) in a single chamber operating at 0.1 Hz. A thick-liquid-wall chamber is proposed to absorb the target emission (X-rays, debris and neutrons) and mitigate the blast effects on the chamber wall. The target is attached to the end of a conical shaped recyclable transmission line (RTL) made from a solid coolant (e.g., frozen flibe), or a material that is easily separable from the coolant (e.g., steel). The RTL/target assembly is inserted through a single opening at the top of the chamber for each shot. This study looks at the RTL material choice from a safety and environmental point of view. Materials were assessed according to waste disposal rating (WDR) and contact dose rate (CDR). Neutronics calculations, using the TART2002 Monte Carlo code from Lawrence Livermore National Laboratory (LLNL), were performed for the RTL and Z-IFE chamber, and key results reported here.

The production of bioethanol increase rapidly because it is renewable energy that can be used to solve energy crisis caused by the depleting of fossil oil. The large scale production bioethanol in industry generally use feedstock such as sugarcane, corn, and cassava that are also required as food resouces. Therefore, many studies on the bioethanol process concerned with the use raw materials that were not competing with food supply. One of the alternative feedstock able to utilize for bioethanol production is the starchy material that available locally namely iles-iles (Amorphophallus mueller Blum. The contain of carbohydrate in the iles-iles tubers is around 71.12 % which is slightly lower as compared to cassava tuber (83,47%. The effect of various starting material, starch concentration, pH, fermentation time were studied. The conversion of starchy material to ethanol have three steps, liquefaction and saccharification were conducted using α-amylase and amyloglucosidase then fermentation by yeast S.cerevisiaie. The highest bioethanol was obtained at following variables starch:water ratio=1:4 ;liquefaction with 0.40 mL α-amylase (4h; saccharification with 0.40 mL amyloglucosidase (40h; fermentation with 10 mL S.cerevisiae (72h producing bioethanol 69,81 g/L from cassava while 53,49 g/L from iles-iles tuber. At the optimum condition, total sugar produced was 33,431 g/L from cassava while 16,175 g/L from iles-iles tuber. The effect of pH revealed that the best ethanol produced was obtained at pH 5.5 during fermentation occurred for both cassava and iles-iles tubers. From the results studied shows that iles-iles tuber is promising feedstock because it is producing bioethanol almost similarly compared to cassava.

    The study describes the epidemiology, treatment, and treatment outcomes of the 10 cases of facial nerve palsy seen in children managed at the Obafemi Awolowo University Teaching Hospitals Complex, Ile-Ife over a 10 year period. It also compares findings with report from developed countries. This was a retrospective cohort review of pediatric cases of facial nerve palsy encountered in all the clinics run by specialists in the above named hospital. A diagnosis of facial palsy was based on International Classification of Diseases, Ninth Revision, Clinical Modification codes. Information retrieved from the case note included sex, age, number of days with lesion prior to presentation in the clinic, diagnosis, treatment, treatment outcome, and referral clinic. Only 10 cases of facial nerve palsy were diagnosed in the institution during the study period. Prevalence of facial nerve palsy in this hospital was 0.01%. The lesion more commonly affected males and the right side of the face. All cases were associated with infections: Mainly mumps (70% of cases). Case management include the use of steroids and eye pads for cases that presented within 7 days; and steroids, eye pad, and physical therapy for cases that presented later. All cases of facial nerve palsy associated with mumps and malaria infection fully recovered. The two cases of facial nerve palsy associated with otitis media only partially recovered. Facial nerve palsy in pediatric patients is more commonly associated with mumps in the study environment. Successes are recorded with steroid therapy.

    We examined the interventions used by nurses to prevent pressure ulcers in 3 hospitals in south west Nigeria and perceived barriers to effective nursing pressure ulcer prevention interventions. One hundred ninety-three nurses were purposively selected from neurological, orthopedic, intensive care, and accident and emergency units of participating hospitals. Study sites were 3 teaching hospitals in south west Nigeria (Lagos State University Teaching Hospital, Lagos; University College Hospital, Ibadan; and Obafemi Awolowo Teaching Hospital Ile-Ife). Data were collected via a structured questionnaire designed for this study. It included 3 sections: demographic information, practices used for pressure ulcer prevention, and perceived barriers to prevention. Sections of the questionnaire that queried interventions and perceived barriers to pressure ulcer prevention were evaluated for face and content validity. Reliability was evaluated via internal consistency; the split half reliability was 0.82. Similar practices regarding pressure ulcer prevention were found across the 3 hospitals. The most commonly used intervention was patient repositioning every 2 hours; the least used intervention was completion of a validated pressure ulcer risk scale. Nurses described using interventions that have not proved effective for pressure ulcer prevention such as massaging bony prominences and application of talcum powder. Nurses identified 2 principal factors that act as barriers to successful prevention of pressure ulcers: inadequate manpower and inadequate supply of linens on the wards. Nurses use a combination of evidence-based interventions, along with interventions that have not proved effective for pressure ulcer prevention. We recommend development of national standards for pressure ulcer prevention in Nigeria that are based on current best evidence and consistent with current international guidelines.

    The work presented outlines the global frame given at the Institute of Nuclear Fusion (DENIM) for having an integral perspective of the different research areas with the development of Inertial Fusion for energy generation. The coupling of a new radiation transport (RT) solver with an existing multi-material fluid dynamics code using Adaptive Mesh Refinement (ARM) is presented in Section 2, including improvements and additional information about the solver precision. In Section 3, new developments in the atomic physics codes under target conditions, to determine populations, opacity data and emissivities have been performed. Exotic and innovative ideas about Inertial Fusion Energy (IFE), as catalytic fuels and Z-pinches have been explored, and they are explained in Section 4. Numerical simulations demonstrate important reductions in the tritium inventory. Section 5 is devoted to safety and environment of the IFE. Uncertainties analysis in activation calculations have been included in the ACAB activation code, and also calculations on pulse activation in IFE reactors and on the activation of target debris in NIF are presented. A comparison of the accidental releases of tritium from some IFE reactors computed using MACCS2 code is explained. Finally, Section 6 contains the research on the basic mechanisms of neutron damage in SiC (low-activation material) and FeCu alloy using the DENIM/LLNL molecular dynamics code MDCASK. (authors)

    Full Text Available The main thrust of this paper is to discuss the development of open and distance education in Nigeria and the major manifestations of the use of information and communication technologies (ICTs in education in open and distance learning. This study further discusses the importance and use of ICTs in open and distance learning in making education accessible to a larger population of students. From that vantage point this paper reviews the phenomenon of ICTs in open and distance learning in developing countries such as Nigeria. The paper identifies a number of issues that impede the effective optimization of ICTs in open and distance learning in developing countries. Prominent among the issues highlighted are poverty, intermittent supply of electricity and language barrier. The paper argues that these problems are to be tackled if the objective of enhancing the potentials of ICTs in open and distance learning in developing countries were to be achieved. On that note the current paper makes some humble suggestions on how to curtail the problems. The study employed descriptive method. An intact class of students that registered for the Bachelor of Education distance learning programme of the Faculty of Education of the Obafemi Awolowo University,Ile-Ife formed the samples used for the study. This was done to collect information on the factors affecting usage of ICT. The result shows that lack of skills rank highest (46.1%, following this is non availability of ICT at home (18.8%, costs (11.3% and non familiarity with ICT (10.6%.

    While high channel density can be easily achieved for big experiments using custom made microchips, providing something similar for small and medium size experiments imposes a challenge. Within this work we describe a novel and cost effective solution to operate silicon photodetectors such as silicon photo multipliers (SiPM). The IFES modules provide the bias voltage for the detectors, a leading edge discriminator featuring time over threshold and a differential amplifier, all on one printed circuit board. We demonstrate under realistic conditions that the module is usable for high resolution timing measurements exploiting both charge and time information. Furthermore we show that the modules can be easily used in larger detector arrays. All in all this confirms that the IFES modules are a viable option for a broad range of experiments if cost-effectiveness and small form factor are required.

    1991-01-01

    The development of inertial fusion as a power source will require achieving four principal milestones: ignition and propagating burn; high gain at low drive energy for the reactor driver; pulse repetition rates of a few Hz; and long-term reliability and economics of a reactor. To keep development time and costs to a minimum, these should be accomplished with as few major facilities as possible. A viable scenario for the Inertial Fusion Energy (IFE) Program would include establishing the first milestone in a Nova Upgrade for ignition and gain and the latter three in an upgradable, low-power Engineering Test Facility (ETF)/Demonstration Power Plant (DPP), i.e. two major facilities. To be successful in as short a time as possible operations at the major facilities would have to be supported by off-line reactor driver and other reactor technology development efforts. These efforts would evaluate and prioritize the myriad of options available at present for power plant and subsystem concepts. This paper describes the elements of such a program that could make the first commercial power available in the decade of the 2020s and estimates the resources needed. This program would be carried out in phases with major go/no-go decision points before each large funding change. It is estimated that an IFE evaluation phase in the early 1990s would cost $100--150 M, a concept development phase in the latter 1990s would cost $500--850 M, and an engineering test and demonstration phase after the year 2000 would cost $6--8 over 20 years

O financiamento da UNB com verbas do MEC não difere muito do observado nas IFES, predominando recursos cadentes num sistema em expansão, no contexto da crise de hegemonia da universidade e de políticas voltadas para uma heterogeneidade no sistema federal. A UNB tem alta proporção de gastos com receitas próprias, vem tendo crescente dependência destas, mas a maioria é consumida na sua geração, mostrando que nenhuma universidade federal de qualidade pode prescindir dos recursos da União. O primeiro dos anteprojetos trouxe notáveis inovações no financiamento das IFES, mas o segundo renunciou a muitas das propostas originais. Exigiu transparência na atuação das fundações de apoio, subordinação a colegiados superiores e sinalizou longinquamente para uma futura reforma da gestão financeira e patrimonial.The text analyses the behavior of expenditures of the University of Brasília (UNB, emphasizing its own revenues, in the context of the financing of Federal Institutions of Higher Education (FISHE, and deals with the university support foundations in preliminary proposals for a higher education reform bill of President Lula Government Administration. The public funding of UNB does not differ substantially from that of FISHE, in which falling resources relative to enrollment growth have prevailed; these are viewed within the framework of a hegemonic crisis of the university and of policies aimed to heterogeneity in the federal system. UNB has a high share of expenditures with its own revenues, and has been increasingly dependent on them, but most has been used up in their production, indicating that public funding is the key to quality

    Full Text Available AIMS: Studies comparing the occurrence and characteristics of work – related musculoskeletal disorders (WMSDs across various occupational groups in the health sector from Sub-Sahara Africa are sparse. This study investigated the prevalence and pattern of WMSDs among health workers in Obafemi Awolowo University Teaching Hospitals complex, Ile-Ife, Nigeria. METHODS: An adapted questionnaire from the Nordic musculoskeletal questionnaire was used as the survey instrument. Data were collected on demographics, lifetime, 12-months and point prevalence, and pattern and consequence of WMSDs. A response rate of 91% was obtained in this study. RESULTS: Sixty eight point seven percent of the respondents have experienced WMSDs in their occupational lives with a higher percentage among males than females (39.6 vs.29.1%. The 12-months period and point prevalence rate of WMSDs was 64.4% and 48.2% respectively. WMSDs reported mostly for low back (50% followed by the shoulder (27.5% and knees (18.1%. Nurses (30.4% had the highest rate of WMSDs among the health workers. Most nurses with complaints (53.4% took a sick leave as a result of WMSDs, followed by doctors (32% and support staff (25%. CONCLUSIONS: WMSDs are common among health workers from Nigeria with the low back being injured most often. The rate of WMSDs and consequent sick leave is higher among nurses than other health workers. Preventive programmes on musculoskeletal disorders among health workers are recommended in order to reduce the rate of WMSDs among them and to promote efficiency in patient care.

    Normal pregnancy is characterised by a reduction in peripheral resistance in order to increase blood flow and facilitate the supply of oxygen and nutrients to the peripheral tissues. The aim of this study was to see the effect of pregnancy on haemorheological profiles based on trimesters. Methods: This study was carried out at Haematology Department of Obafemi Awolowo University Teaching Hospital Complex, Ile-Ife, Nigeria. Sixty pregnant and twenty non-pregnant women were included. Estimation of packed cell volume, erythrocyte sedimentation rate, relative plasma viscosity, relative whole blood viscosity, and fibrinogen concentration were carried out based on trimesters using standard approved methods. Results: The mean of packed cell volume (PCV), erythrocyte sedimentation rate (ESR), and relative plasma viscosity (RPV) were 0.33L/L, 26.10 mm/1 Hr, and 1.70 mPa.s, while that of relative whole blood viscosity (RWBV) and fibrinogen concentration (FIBC) were 3.88 mPa.s and 4.38g/L. In the second trimester, the mean PCV was 0.32L/L, mean ESR was 43.20 mm/1 Hr, RPV was 1.72 mPa.s, WBV 3.50 mPa.s and FIBC 4.86 g/L. For the third trimester, the means were: PCV 0.29 L/L, ESR 86.65 mm/1 Hr, RPV 1.77 mPa.s, and RWB 3.88 mPa.s while FIBC was 5.04 g. Conclusion: Normal pregnancy exerts positive influence on haemorheological profiles and this could explain the reduced risk of cardiovascular disease in pregnancy. Haemorheological profiles can be used to monitor the development of cardiovascular disease during pregnancy. (author)

    The ARIES-IFE study was an integrated study of inertial fusion energy (IFE) chambers and chamber interfaces with the driver and target systems. Detailed analysis of various subsystems was performed parametrically to uncover key physics/technology uncertainties and to identify constraints imposed by each subsystem. In this paper, these constraints (e.g., target injection and tracking, thermal response of the first wall, and driver propagation and focusing) were combined to understand the trade-offs, to develop operational windows for chamber concepts, and to identify high-leverage research and development directions for IFE research. Some conclusions drawn in this paper are (a) the detailed characterization of the target yield and spectrum has a major impact on the chamber; (b) it is prudent to use a thin armor instead of a monolithic first wall for dry-wall concepts; (c) for dry-wall concepts with direct-drive targets, the most stringent constraint is imposed by target survival during the injection process; (d) for relatively low yield targets (<250 MJ), an operational window with no buffer gas may exist; (e) for dry-wall concepts with indirect-drive targets, a high buffer gas pressure would be necessary that may preclude propagation of the laser driver and require assisted pinch transport for the heavy-ion driver; and (f) generation and transport of aerosols in the chamber is the key feasibility issue for wetted-wall concepts

    Inertial fusion research is approaching a critical milestone, namely the demonstration of ignition and burn. The world's largest high-power laser, the National Ignition Facility (NIF), is under operation at the Lawrence Livermore National Laboratory (LLNL), in the USA. Another ignition machine, Laser Mega Joule (LMJ), is under construction at the CEA/CESTA research centre in France. In relation to the National Ignition Campaign (NIC) at LLNL, worldwide studies on inertial fusion applications to energy production are growing. Advanced ignition schemes such as fast ignition, shock ignition and impact ignition, and the inertial fusion energy (IFE) technology are under development. In particular, the Fast Ignition Realization Experiment (FIREX) at the Institute of Laser Engineering (ILE), Osaka University, and the OMEGA-EP project at the Laboratory for Laser Energetics (LLE), University Rochester, and the HiPER project in the European Union (EU) for fast ignition and shock ignition are progressing. The IFE technology research and development are advanced in the frameworks of the HiPER project in EU and the LIFE project in the USA. Laser technology developments in the USA, EU, Japan and Korea were major highlights in the IAEA FEC 2010. In this paper, the status and prospects of IFE science and technology are described.

    This paper reports on a new design of a multi-megajoule KrF laser driver for the Prometheus inertial fusion energy (IFE) reactor c. year 2050 which has been developed exploiting advances achieved in non-linear optics (NLO) during the past decade. Optimized excimer e-beam sustained electric-discharge lasers (EBSEDLs) are predicted to produce output energies too low (∼4 kJ) with pulses too long (∼500 ns) to meet IFE target irradiation requirements ΔE target ∼ 5 MJ, τ target (∼ 6 ns). The NLO devices used in this design permit the independent optimization of excimer laser modules while providing the important functions of coherent beam combination, intensity smoothing, and temporal pulse compression at high efficiencies

  17. The solenoidal transport option: IFE drivers, near term research facilities, and beam dynamics

    International Nuclear Information System (INIS)

    Lee, E.P.; Briggs, R.J.

    1997-09-01

    Solenoidal magnets have been used as the beam transport system in all the high current electron induction accelerators that have been built in the past several decades. They have also been considered for the front end transport system for heavy ion accelerators for Inertial Fusion Energy (IFE) drivers, but this option has received very little attention in recent years. The analysis reported here was stimulated mainly by the recent effort to define an affordable open-quotes Integrated Research Experimentclose quotes (IRE) that can meet the near term needs of the IFE program. The 1996 FESAC IFE review panel agreed that an integrated experiment is needed to fully resolve IFE heavy ion driver science and technology issues; specifically, open-quotes the basic beam dynamics issues in the accelerator, the final focusing and transport issues in a reactor-relevant beam parameter regime, and the target heating phenomenologyclose quotes. The development of concepts that can meet these technical objectives and still stay within the severe cost constraints all new fusion proposals will encounter is a formidable challenge. Solenoidal transport has a very favorable scaling as the particle mass is decreased (the main reason why it is preferred for electrons in the region below 50 MeV). This was recognized in a recent conceptual study of high intensity induction linac-based proton accelerators for Accelerator Driven Transmutation Technologies, where solenoidal transport was chosen for the front end. Reducing the ion mass is an obvious scaling to exploit in an IRE design, since the output beam voltage will necessarily be much lower than that of a full scale driver, so solenoids should certainly be considered as one option for this experiment as well

    The high average power laser (HAPL) program aims at developing laser inertial fusion energy (Laser IFE) based on lasers, direct drive targets and a solid wall chamber. The preferred first wall configuration is based on tungsten and ferritic steel as armor and structural materials, respectively. A key concern is the survival of the first wall under the X-ray and ion energy deposition from the fusion micro-explosion. The HAPL design and R and D effort in the chamber and material area is focused toward understanding and resolving the key armor survival issues. This includes modeling and experimental testing of the armor thermo-mechanical behavior in facilities utilizing ion, X-rays and laser sources to simulate IFE conditions. Helium management is addressed by conducting implantation experiments along with modeling of He behavior in tungsten. This paper summarizes the HAPL chamber activities. The first wall/armor configuration and design analysis are described, key chamber issues are discussed, and the R and D to address them is highlighted

    An on-site inspection (OSI) is the third of four elements of the verification regime of the Comprehensive Nuclear-Test-Ban Treaty (CTBT). The sole purpose of an OSI is to confirm whether a nuclear weapon test explosion or any other nuclear explosion has been carried out in violation of the treaty and to gather any facts which might assist in identifying any possible violator. It thus constitutes the final verification measure under the CTBT if all other available measures are not able to confirm the nature of a suspicious event. The Provisional Technical Secretariat (PTS) carried out the Integrated Field Exercise 2014 (IFE14) in the Dead Sea Area of Jordan from 3 November to 9. December 2014. It was a fictitious OSI whose aim was to test the inspection capabilities in an integrated manner. The technologies allowed during an OSI are listed in the Treaty. The aim of the Seismic Aftershock Monitoring System (SAMS) is to detect and localize aftershocks of low magnitudes of the triggering event or collapses of underground cavities. The locations of these events are expected in the vicinity of a possible previous explosion and help to narrow down the search area within an inspection area (IA) of an OSI. The success of SAMS depends on the main elements, hardware, software, deployment strategy, the search logic and not least the effective use of personnel. All elements of SAMS were tested and improved during the Built-Up Exercises (BUE) which took place in Austria and Hungary. IFE14 provided more realistic climatic and hazardous terrain conditions with limited resources. Significant variations in topography of the IA of IFE14 in the mountainous Dead Sea Area of Jordan led to considerable challenges which were not expected from experiences encountered during BUE. The SAMS uses mini arrays with an aperture of about 100 meters and with a total of 4 elements. The station network deployed during IFE14 and results of the data analysis will be presented. Possible aftershocks of

  6. The Awolowo – Akintola Leadership Tussle: A Reinterpretation

    Directory of Open Access Journals (Sweden)

    Emmanuel Oladipo Ojo

    2016-01-01

    Full Text Available The underlying causes and consequences of the Awolowo–Akintola leadership tussle which began in the defunct Western Region and spilled to other parts of Nigeria have attracted quite a great deal of deliberate and inadvertent misinterpretations and falsehoods. While the principal actors and their disciples struggled to swing the pendulum of justification and ‘truth’ to their respective sides; most of the inferences, references, rebuttals and conclusions of scholars on the underlying causes of the rift are not consistent with facts. Ostensibly, the rift was the outcome of Chief Obafemi Awolowo’s reluctance to hand over to Ladoke Akintola as Premier of Western Nigeria following the former’s resolve to contest the 1959 federal elections into the Central Legislature; Akintola’s desire to be the de jure Premier of Western Nigeria; his pointed opposition to the Action Group’s adoption of a socialist ideology on the eve of independence, the so called ‘Coca-Cola War’ between the wives of the duo as well as Akintola’s interface with the Northern People’s Congress, NPC. The last was Akintola’s supposed gravest offence. While scholars have almost over-flogged the other causes of the Akintola–Awolowo leadership tussle, there is paucity of literature, or at best parried accounts, on the epicentre of the crisis – Akintola’s political interface with Northern Nigeria political leaders. This paper intends to fill this gap by attempting a reinterpretation of some of the factors that may have influenced the political rapport between Akintola and NPC leaders.

    2002-01-01

    The choice of target coating and hohlraum wall materials is among the most critical decisions to be made for inertial fusion energy (IFE) designs. Gold and gold/gadolinium have long been considered to be the coating and hohlraum wall materials of choice for direct drive (DD) and indirect drive (ID) targets, respectively, offering high target performance and low beam energy losses. More recently, a variety of other materials have been considered, including W, Pb, Pt, Pd, and Ag for the DD target coating and Au, W, Pb, Hg, Ta, Cs, and Hf for the hohlraum wall of the ID target. The choice of the coating/hohlraum material is a tradeoff between the target design elements such as safety, target physics, economics, etc. We identified the key safety issues and have investigated the neutron-induced irradiation effects of the candidate coating/hohlraum materials using the radiation chamber conditions of the ARIES-IFE dry wall concept. The safety requirements have specific impacts in terms of the coating/hohlraum materials choice

    Full Text Available The increase in demand for university education remains unmet especially in developing countries; this has made adoption of distance education imperative in our educational system. Information and Communications Technology (ICT has been identified as a tool for improving education quality especially in developing countries. The study examined attitudes and perceptions of nursing students toward using Information and Communications Technology supports in distance education. A researchers‐designed and validated questionnaire with alpha coefficient of .82 was administered to 396 students of the Department of Nursing Science, Obafemi Awolowo University, Ile‐Ife, Nigeria out of which 305 (70% were returned. Findings of the study revealed that the majority of the nurses (83.3% had never attended any online computer based training program, a majority (63.9% had no formal computer training and do not possess personal computers, while 74.4% reported positive perception and attitudes toward using ICT supports in distance education. Lack of constant internet access was rated by the respondents (29.8% as a major challenge to e‐learning support. Gender and years of working experience had no significant influence on respondents’ attitudes and perceptions toward ICT supports.

    Of the building blocks of an inertial fusion energy (IFE) plant, target fabrication remains a significant credibility issue. For this reason, an extensive parametric study has been conducted on mass production of glow discharge polymer (GDP) shells in a vertical fluidized bed. Trans-2-butene was used as a reactant gas with hydrogen as a diluting and etching agent. Coating rates in the range of 1 to 2 μm/h were demonstrated on batches of 30 shells where National Ignition Facility-quality surfaces were obtained for 3- to 5-μm-thick coatings. Thick coatings up to 325 μm were also demonstrated that are visually transparent, without void and stress fracture. A phenomenological understanding of the GDP growth mechanisms to guide future experiments was further established. Specifically, gas-phase precipitation and high-impact collisions were identified as the main surface-roughening mechanisms. The former produces dense cauliflower-like surface patterns that can be eliminated by adjusting the gas flow rates and the flow ratio. The latter produces isolated domelike surface defects that can be reduced by introducing concerted motion between the shells. By converting from a vertical to a horizontal configuration, fully transparent coatings were obtained on 350 shells. Collisions in a fluidized bed have been identified as the limiting factor in meeting IFE specifications, and a related-rotary kiln technique is recommended for scale-up

    The activities of direct drive implosion experiments at ILE of Osaka Univ. are focused on the planar- and spherical-target experiments relating to Rayleigh-Taylor instability and the implosion experiments of cryogenic targets with low density plastic foam shell overcoated by a solid plastic layer. In the spherical shell target implosions a very early x-ray emission (refer as pre-emission hereafter) has been observed at the center of the target. The appearance of the pre-emission is related to the illumination nonuniformity. The appearance time of the pre-emission, the electron temperature of the source plasma of the pre-emission and the possibility of Rayleigh-Taylor instability have been studied experimentally to understand the mechanism of the pre-emission. Shell break up by Rayleigh-Taylor instability has been concluded to be the most probable mechanism of the pre-emission

    Various studies have reported poor awareness and knowledge of dentistry in the Nigerian population. There is, however, paucity of information assessing the knowledge and awareness of medical doctors/students and nurses about dentistry. The present study is aimed at determining the knowledge and awareness of medical doctors/students and nurses about dentistry. Self-administered questionnaires were randomly distributed among medical doctors/students, and nurses of Obafemi Awolowo Teaching Hospitals' Complex, Ile-Ife, Nigeria. Information collected using the questionnaire included participants' biodata, questions evaluating dental awareness, knowledge of systemic and oral health connections as well as referral practices. The data analysis was done with STATA version 11 software. A total of 300 questionnaires were randomly distributed among doctors/students and nurses, 206 were returned (response rate of 69%). Of the returned questionnaires, 129(63%) were males and 77(37%) were females. There were 42 medical doctors, 49 nurses and 115 medical students. The mean age of the participants was 26.7 years (SD 5.2). Majority (99.5%) was aware of dental profession, but 92% had never referred patients for dental consultation. One third (31%) of medical doctors believed that Ludwig angina was a cardiac disease. A large proportion of the respondents (61%) see no need for routine dental visit while 27% would want to visit the dentist only when they had a dental complaint. Although a large percentage of the participants claimed to be aware of dentistry, our findings revealed low level of knowledge and attitude to Dentistry. Efforts should be made towards closing this knowledge gap to achieve efficient oral health.

    Full Text Available The decrease in production and the raise in needs have led to the rise in oil prices. This work investigated the possibility of Iles-iles (Amorphophallus campanulatus tuber flour, which is rich in carbohydrate con-tent, as a raw material to produce bioethanol. To obtain the maximum ethanol concentration, several parameters had been studied, such as: the concentration of α-amylase and β-amylase in liquefaction and sac-charification processes, respectively, the type of S. cerevisiae enzyme (pure, dry, wet and instant and weight of Diammonium phosphate (DAP as a nutrient for S. cerevisiae in fermentation. The result shows that the highest reducing sugar content (12.5% was achieved when 3.2 ml α-amylase/kg flour and 6.4 ml β-amylase/kg flour were used during liquefaction and saccharification processes. Since the concentration of α- and β-amylase increased, the reducing sugar obtained also increased. The higher sugar content resulted the higher the ethanol concentration in the fermentation broth. Furthermore, the highest concentration of ethanol (9 %v/v was obtained at 72 h fermentation using the dry S. cerevisiae, at 3.2 ml and 6.4 ml /kg flour of α-amylase and β-amylase enzymes, respectively. From the study of the effect of S. cerevisiae type, it was shown that dry S. cereviseae produced the highest ethanol concentration 10.2% (v/v at 72 h fermentation. The DAP was used as a nitrogen supply required by S. cerevisiae to growth and as a results can increase the ethanol concentration. The addition of DAP in the fermentation proved that 8.45% (v/v of ethanol was obtained. This result shows that the proposed tuber flour has the potential a raw material for bioethanol production. © 2014 BCREC UNDIP.

    The modeling of aerosols is a major stake in the understanding of the emission processes and evolution of particulates in the atmosphere. However, the parameterizations used in today's aerosol models still comprise many uncertainties. This work has been motivated by the need of better identifying the weaknesses of aerosols modeling tools and by the necessity of having new validation methods for a 3D evaluation of models. The studies have been carried out using the CHIMERE chemistry-transport model, which allows to simulate the concentrations and physico-chemical characteristics of pollution aerosols at the European scale and in Ile-de-France region. The validation approach used is based on the complementarity of the measurements performed on the ground by monitoring networks with those acquired during the ESQUIF campaign (study and simulation of air quality in Ile-de-France), with lidar and photometric measurements and with satellite observations. The comparison between the observations and the simulations has permitted to identify and reduce the modeling errors, and to characterize the aerosol properties in the vicinity of an urban area.

  2. Possible approaches to fast quality control of IFE targets

    2006-01-01

    In recent years, research into the development of reliable methods and techniques for characterization and quality control of ICF/IFE targets has been carried out very actively. This is motivated by the need to provide the means for precise and accurate knowledge of cryogenic target parameters. On the other hand, particular emphasis should be paid to the fact that fuelling of a commercial power plant requires ∼6 targets each second. This indicates that the development of fast quality control techniques is of critical importance as well. Therefore, in this report we discuss the issues underlying the construction of different algorithms for characterization and quality control of ICF/IFE targets. Among them are: (a) algorithm banks and their structure, (b) algorithm testing, (c) target reconstruction experiments. The algorithm bank incorporates the algorithms for two stages of target production: the stage of fuel layering technique development (motionless target) and the stage of cryogenic target delivery (injected target). In the first case an inverse algorithm for individual target characterization (3D target reconstruction) and two threshold algorithms for fast control of target quality are presented. They are based on tomographic information processing methods. Experimentally, tomographic data acquisition is carried out by a hundred projections microtomograph. The spatial resolution of the optical system of the microtomograph is 1 μm for 490 nm wavelength, the accuracy of target angular positioning is ±1.5-2.5 min. In the second case we describe the algorithm based on Fourier transform holography for ultra fast target characterization during its injection. The performed computer experiments have demonstrated much promise of this approach in the following directions: recognition of the target imperfections in both low- and high- harmonics; quality control of both a single target and a target batch; simultaneous control of both an injected target quality and

CDs produce clinical symptoms and signs over several days before culminating in death. They are also amenable to treatment with antimicrobials if affected persons present early. We sought to find out the incidence of CD-related SD at the Ladoke Akintola University of Technology Teaching Hospital (Osogbo, Osun State, Nigeria – a tertiary health facility in southwest Nigeria – and the prevailing associated factors. Methods: We conducted a retrospective study of CD-related SD in adult patients aged 18 years and older that occurred from January 2003 to December 2011. The Statistical Package for the Social Sciences version 16 was used for analysis of the generated data. Percentages and frequencies were calculated. Results: There were 17 (39.6% CD-related SDs out of the 48 cases of SD studied. CD-related SD also accounted for 2.4% of all adult medical admissions. The mean age of the patients was 37.6 ± 11.6 years, age range of 25–62 years, mode of 25 years, and median 34 years. The male-to-female ratio was 1.8:1. Typhoid sepsis was responsible for SD in 47.1% of patients, pulmonary tuberculosis in 17.7% of patients, and lobar pneumonia in 17.7% of patients. The most affected age group was the 20–29-year-old group

    At present pathogenic mechanisms of cancer cachexia are poorly understood. Previous evidence in animal models implicates the melanocortin-4 receptor gene (MC4R) in the development of cancer cachexia. In humans, MC4R mutations that lead to an impaired receptor function are associated with obesity; in contrast, the most frequent polymorphism (Val103Ile, rs2229616; heterozygote frequency approximately 2%) was shown to be negatively associated with obesity. We tested if cancer patients that are homo-/heterozygous for the Val103Ile polymorphism are more likely to develop cachexia and/or a loss of appetite than non-carriers of the 103Ile-allele. BMI (body mass index in kg/m 2 ) of 509 patients (295 males) with malignant neoplasms was determined; additionally patients were asked about premorbid/pretherapeutical changes of appetite and weight loss. Cachexia was defined as a weight loss of at least 5% prior to initiation of therapy; to fulfil this criterion this weight loss had to occur independently of other plausible reasons; in single cases weight loss was the initial reason for seeing a physician. The average age in years (± SD) was 59.0 ± 14.5 (males: 58.8 ± 14.0, females 59.2 ± 14.0). Blood samples were taken for genotyping of the Val103Ile by PCR- RFLP. Most of the patients suffered from lymphoma, leukaemia and gastrointestinal tumours. 107 of the patients (21%) fulfilled our criteria for cancer cachexia. We did not detect association between the Val103Ile polymorphism and cancer cachexia. However, if we exploratively excluded the patients with early leucaemic stages, we detected a trend towards the opposite effect (p < 0.05); heterozygotes for the 103Ile-allele developed cancer cachexia less frequently in comparison to the rest of the study group. Changes of appetite were not associated with the 103Ile-allele carrier status (p > 0.39). Heterozygotes for the 103Ile-allele are not more prone to develop cancer cachexia than patients without this allele; possibly

    Highlights: • The safety characteristics and at risk inventories in an IFE facility are discussed. • The primary nuclear hazard is the potential exposure of workers and/or the public to tritium and/or neutronically activated products. • Recent technology developments in tritium processing are key for minimization of inventories. • Initial safety studies indicate that hazards associated to the use of liquid lithium can be appropriately managed. • Simulation of worst-case scenarios indicate that the accident consequences are limited and below the limit for public evacuation. - Abstract: Over the past five years, the fusion energy group at Lawrence Livermore National Laboratory (LLNL) has made significant progress in the area of safety and tritium research for Inertial Fusion Energy (IFE). Focus has been driven towards the minimization of inventories, accident safety, development of safety guidelines and licensing considerations. Recent technology developments in tritium processing and target fill have had a major impact on reduction of tritium inventories in the facility. A safety advantage of inertial fusion energy using indirect-drive targets is that the structural materials surrounding the fusion reactions can be protected from target emissions by a low-pressure chamber fill gas, therefore eliminating plasma-material erosion as a source of activated dust production. An important inherent safety advantage of IFE when compared to other magnetic fusion energy (MFE) concepts that have been proposed to-date (including ITER), is that loss of plasma control events with the potential to damage the first wall, such as disruptions, are non-conceivable, therefore eliminating a number of potential accident initiators and radioactive in-vessel source term generation. In this paper, we present an overview of the safety assessments performed to-date, comparing results to the US DOE Fusion Safety Standards guidelines and the recent lessons-learnt from ITER safety and

    Z-Pinch Inertial Fusion Energy (Z-IFE) complements and extends the single-shot z-pinch fusion program on Z to a repetitive, high-yield, power plant scenario that can be used for the production of electricity, transmutation of nuclear waste, and hydrogen production, all with no CO 2 production and no long-lived radioactive nuclear waste. The Z-IFE concept uses a Linear Transformer Driver (LTD) accelerator, and a Recyclable Transmission Line (RTL) to connect the LTD driver to a high-yield fusion target inside a thick-liquid-wall power plant chamber. Results of RTL and LTD research are reported here, that include: (1) The key physics issues for RTLs involve the power flow at the high linear current densities that occur near the target (up to 5 MA/cm). These issues include surface heating, melting, ablation, plasma formation, electron flow, magnetic insulation, conductivity changes, magnetic field diffusion changes, possible ion flow, and RTL mass motion. These issues are studied theoretically, computationally (with the ALEGRA and LSP codes), and will work at 5 MA/cm or higher, with anode-cathode gaps as small as 2 mm. (2) An RTL misalignment sensitivity study has been performed using a 3D circuit model. Results show very small load current variations for significant RTL misalignments. (3) The key structural issues for RTLs involve optimizing the RTL strength (varying shape, ribs, etc.) while minimizing the RTL mass. Optimization studies show RTL mass reductions by factors of three or more. (4) Fabrication and pressure testing of Z-PoP (Proof-of-Principle) size RTLs are successfully reported here. (5) Modeling of the effect of initial RTL imperfections on the buckling pressure has been performed. Results show that the curved RTL offers a much greater buckling pressure as well as less sensitivity to imperfections than three other RTL designs.

  8. Modeling of pollution aerosols in Ile-de-France

    Hodzic, A.

    2005-10-01

    The modeling of aerosols is a major stake in the understanding of the emission processes and evolution of particulates in the atmosphere. However, the parameterizations used in today's aerosol models still comprise many uncertainties. This work has been motivated by the need of better identifying the weaknesses of aerosols modeling tools and by the necessity of having new validation methods for a 3D evaluation of models. The studies have been carried out using the CHIMERE chemistry-transport model, which allows to simulate the concentrations and physico-chemical characteristics of pollution aerosols at the European scale and in Ile-de-France region. The validation approach used is based on the complementarity of the measurements performed on the ground by monitoring networks with those acquired during the ESQUIF campaign (study and simulation of air quality in Ile-de-France), with lidar and photometric measurements and with satellite observations. The comparison between the observations and the simulations has permitted to identify and reduce the modeling errors, and to characterize the aerosol properties in the vicinity of an urban area.

    Water management for the Mille Iles River, which supplies drinking water to 400,000 people, was discussed with reference to solutions for critically low water flow which was experienced in 2001 and 2002. The river is part of the Lac des Deux Montagnes watershed in the region of Montreal which is characterized as a high population growth area. In the summer of 2001, municipalities served by the Mille Iles River were faced with problems in the supply of drinking water when the river flow reached only 13 cubic metres per second. The minimal values of flow observed for this time of year have rarely been under 20 cubic metres per second since 1970. The quality of water was reduced under such conditions of flow because the dilution of wastewater discharged into the river became so weak that the aging water treatment facilities had to work beyond their capacity. Quebec's Center of Water Expertise (CEHQ) intervened in an emergency measure to ensure water quality. This study investigated the following 3 possible scenarios for a solution to this problem: (1) to increase the Mille Iles River capacity at the Lac des Deux Montagnes outlet, (2) to reduce the flow discharged by the 3 other outlets of Lac des Deux Montagnes, and (3) to increase the inflow to Lac des Deux Montagnes from reservoirs located in the Ottawa River watershed. The first solution was favoured. 2 refs., 1 tab., 8 figs.

To assess this relationship more precisely, a meta-analysis was performed. Ultimately, 43 case-control studies, comprising 19,228 subjects were included. A significantly elevated lung cancer risk was associated with 2 Ile462Val genotype variants (for Val/Val vs Ile/Ile: OR = 1.22, 95% CI = 1.08-1.40; for (Ile/Val +Val/Val vs Ile/Ile: OR = 1.15, 95% CI = 1.07-1.23 in overall population. In the stratified analysis, a significant association was found in Asians, Caucasians and lung SCC, not lung AC and lung SCLC. Additionally, a significant association was found in smoker population and not found in non-smoker populations. This meta-analysis suggests that the Ile462Val polymorphisms of CYP1A1 correlate with increased lung cancer susceptibility in Asian and Caucasian populations and there is an interaction with smoking status, but these associations vary in different histological types of lung caner.

    Upper gastrointestinal bleeding (UGIB) remains a common medical problem worldwide that has significant associated morbidity, mortality, and health care resource use. This study outlines the aetiology, clinical presentation, and treatment outcomes of patients with UGIB in a Nigerian low resource health facility. This was a descriptive study of consecutive patients who underwent upper gastrointestinal (GI) endoscopy for upper GI bleeding in the endoscopy unit of the Obafemi Awolowo University Teaching Hospital Complex, Ile-Ife, Osun State, Nigeria from January 2007 to December 2013. During the study period, 287 (12.4%) of 2,320 patients who underwent upper GI endoscopies had UGIB. Of these, 206 (72.0%) patients were males and their ages ranged from 3 to 100 years with a median age of 49 years. The main clinical presentation included passage of melaena stool in 268 (93.4%) of individuals, 173 (60.3%) had haematemesis, 110 (38.3%) had haematochezia, and 161 (56.1%) were dizzy at presentation. Observed in 88 (30.6%) of UGIB patients, duodenal ulcer was the most common cause, followed by varices [52 (18.1%)] and gastritis [51 (17.1%)]. For variceal bleeding, 15 (28.8%) and 21 (40.4%) of patients had injection sclerotherapy and variceal band ligation, respectively. The overall rebleeding rate for endoscopic therapy for varices was 16.7%. For patients with ulcers, only 42 of 55 who had Forrest grade Ia to IIb ulcers were offered endoscopic therapy. Endoscopic therapy was áin 90.5% of the cases. No rebleeding followed endoscopic therapy for the ulcers. The obtained Rockall scores ranged from 2 to 10 and the median was 5.0. Of all patients, 92.7% had medium or high risk scores. An increase in Rockall score was significantly associated with length of hospital stay and mortality (p < 0.001). The overall mortality rate was 5.9% (17 patients). Endoscopic therapy for UGIB in a resource-poor setting such as Nigeria is feasible, significantly reduces morbidity and mortality

    Full Text Available Although various patterns of renal diseases have been reported from different renal biopsy registries worldwide, data from Nigeria remain scanty. A 10-year retrospective review of renal biopsies was conducted in our tertiary health care facility. All cases were reclassified based on their light microscopic features after the application of standard histochemical stains. A total of 165 cases were reviewed with a male:female ratio of 1.8:1 and a mean age of 15.4 ± 12.0 years. About 69.7% of the cases were below the age of 16 years, while only 2.4% were older than 50 years. The most common indications for biopsy were nephrotic syndrome (72.1% and acute renal failure of unknown etiology (11.5%. Overall, glomerulonephritis (80% was the most common histologic category and occurred only in individuals younger than 50 years old. Minimal change disease (22.9% and membranoproliferative glomerulonephritis (21.9% were the most common varieties in children, while membranous glomerulonephritis (30.6% and focal segmental glomerulosclerosis (27.8% were the commonest among the adult population. The initial histologic diagnosis was revised in 18 cases while a diagnosis was arrived at in seven cases initially adjudged as inadequate for assessment. This study showed that renal biopsy was predominantly performed in children and adolescents. Although glomerulonephritis was the predominant disease, the predominant histologic patterns varied with the patient age. Despite the scarcity of advanced diagnostic tools in resource-poor environments, routine use of histochemical stains is helpful in the evaluation of renal biopsies.

    The monitoring and genotyping of Enterovirus (EV) infections can help to associate particular or severe clinical manifestations with specific EV types and to identify the aetiology of infectious outbreaks. To describe the epidemiological features of EV infections diagnosed during the year 2013 in the Greater Paris area (Ile de France). During 2013, 2497 samples taken from 470 patients in 33 hospitals of Ile-de France were tested for EV genome by RT-PCR. EV genotyping was performed by the National Reference Centre (NRC) laboratories. EV infections were retrospectively reviewed by retrieving clinical and genotyping data from the NRC database. Of the 2497 samples, 490 (19.6%) was positive for EV genome detection. These EV infections represented 88.7% and 24.1%, respectively, of all reported regional and national infections. Twenty-seven different genotypes were identified. Echovirus 30 (E-30) accounted for 54.1% of all characterized strains and caused a large outbreak. Four severe neonatal infections were reported, of which two were caused by EV-A71. Respiratory infections involving EV-D68 were observed in two adults. One fatal case of Coxsackievirus A2-associated myocarditis was reported. Monitoring EV infections in combination with EV genotyping via the French EV network characterized the epidemiology of EV infections in the Ile de France region in 2013 and documented severe EV infections associated with EV-A71 or CV-A2.

      Preston, Roger J S

      2012-02-01

      We report a kindred with heritable protein C (PC) deficiency in which two siblings with severe thrombosis showed a composite type I and IIb PC deficiency phenotype, identified using commercial PC assays (proband: PC antigen 42 u\\/dl, amidolytic activity 40 u\\/dl, anticoagulant activity 9 u\\/dl). The independent PROC nucleotide variations c.669C>A (predictive of Ser181Arg) and c.131C>T (predictive of Asn2Ile) segregated with the type I and type IIb PC deficiency phenotypes respectively, but co-segregated in the siblings with severe thrombosis. Soluble thrombomodulin (sTM)-mediated inhibition of plasma thrombin generation from an individual with PC-Asn2Ile was lower (endogenous thrombin potential (ETP) 56 +\\/- 1% that of ETP determined without sTM) than control plasma (ETP 15 +\\/- 2%) indicating reduced PC anticoagulant activity. Recombinant APC-Asn2Ile exhibited normal amidolytic activity but impaired anticoagulant activity. Protein S (PS)-dependent anticoagulant activity of recombinant APC-Asn2Ile and binding of recombinant APC-Asn2Ile to endothelial protein C receptor (EPCR) were reduced compared to recombinant wild-type APC. Asn2 lies within the omega-loop of the PC\\/APC Gla domain and this region is critical for calcium-induced folding and subsequent interactions with anionic phospholipids, EPCR and PS. The disruption of these interactions in this naturally-occurring PC variant highlights their collective importance in mediating APC anticoagulant activity in vivo.

      Target materials for inertial fusion energy (IFE) power plant designs might be selected for a wide variety of reasons including wall absorption of driver energy, material opacity, cost and ease of fabrication. While each of these issues are of great importance, target materials should also be selected based upon their safety and environmental (S&E) characteristics. The present work focuses on the recycling, waste management and accident dose characteristics of potential target materials. If target materials are recycled so that the quantity is small, isotopic separation may be economically viable. Therefore, calculations have been completed for all stable isotopes for all elements from lithium to polonium. The results of these calculations are used to identify specific isotopes and elements that are most likely to be offensive as well as those most likely to be acceptable in terms of their S&E characteristics.

    12. The Active Jasmonate JA-Ile Regulates a Specific Subset of Plant Jasmonate-Mediated Resistance to Herbivores in Nature

      Directory of Open Access Journals (Sweden)

      Meredith C. Schuman

      2018-06-01

      Full Text Available The jasmonate hormones are essential regulators of plant defense against herbivores and include several dozen derivatives of the oxylipin jasmonic acid (JA. Among these, the conjugate jasmonoyl isoleucine (JA-Ile has been shown to interact directly with the jasmonate co-receptor complex to regulate responses to jasmonate signaling. However, functional studies indicate that some aspects of jasmonate-mediated defense are not regulated by JA-Ile. Thus, it is not clear whether JA-Ile is best characterized as the master jasmonate regulator of defense, or if it regulates more specific aspects. We investigated possible functions of JA-Ile in anti-herbivore resistance of the wild tobacco Nicotiana attenuata, a model system for plant-herbivore interactions. We first analyzed the soluble and volatile secondary metabolomes of irJAR4xirJAR6, asLOX3, and WT plants, as well as an RNAi line targeting the jasmonate co-receptor CORONATINE INSENSITIVE 1 (irCOI1, following a standardized herbivory treatment. irJAR4xirJAR6 were the most similar to WT plants, having a ca. 60% overlap in differentially regulated metabolites with either asLOX3 or irCOI1. In contrast, while at least 25 volatiles differed between irCOI1 or asLOX3 and WT plants, there were few or no differences in herbivore-induced volatile emission between irJAR4xirJAR6 and WT plants, in glasshouse- or field-collected samples. We then measured the susceptibility of jasmonate-deficient vs. JA-Ile-deficient plants in nature, in comparison to wild-type (WT controls, and found that JA-Ile-deficient plants (irJAR4xirJAR6 are much better defended even than a mildly jasmonate-deficient line (asLOX3. The differences among lines could be attributed to differences in damage from specific herbivores, which appeared to prefer either one or the other jasmonate-deficient phenotype. We further investigated the elicitation of one herbivore-induced volatile known to be jasmonate-regulated and to mediate resistance to

      Envelope protein domain III (ED3) of the dengue virus is important for both antibody binding and host cell interaction. Here, we focused on how a L387I mutation in the protein core could take place in DEN4 ED3, but cannot be accommodated in DEN3 ED3 without destabilizing its structure. To this end, we modeled a DEN4-L387I structure using the Penultimate Rotamer Library and taking the DEN4 ED3 main-chain as a fixed template. We found that three out of seven Ile{sup 387} conformers fit in DEN4 ED3 without introducing the severe atomic clashes that are observed when DEN3 serotype’s ED3 is used as a template. A more extensive search using 273 side-chain rotamers of the residues surrounding Ile{sup 387} confirmed this prediction. In order to assess the prediction, we determined the crystal structure of DEN4-L387I at 2 Å resolution. Ile{sup 387} indeed adopted one of the three predicted rotamers. Altogether, this study demonstrates that the effects of single mutations are to a large extent successfully predicted by systematically modeling the side-chain structures of the mutated as well as those of its surrounding residues using fixed main-chain structures and assessing inter-atomic steric clashes. More accurate and reliable predictions require considering sub-angstrom main-chain deformation, which remains a challenging task. - Highlights: • We mutated L387I of DEN4 ED3 and examined its effects on structure and stability. • We modeled the side-chain of Ile{sup 387} using DEN4 ED3's structure as a template. • We determined the crystal structure of DEN4-L387I and confirmed the modeling. • Side-chain repacking occurring around Ile{sup 387} involved >3 inter-connected residues. • These results explained why L387I mutation in DEN4 ED3 conserves thermostability.

    19. Kinetic proofreading at single molecular level: aminoacylation of tRNA(Ile and the role of water as an editor.

      Full Text Available Proofreading/editing in protein synthesis is essential for accurate translation of information from the genetic code. In this article we present a theoretical investigation of efficiency of a kinetic proofreading mechanism that employs hydrolysis of the wrong substrate as the discriminatory step in enzyme catalytic reactions. We consider aminoacylation of tRNA(Ile which is a crucial step in protein synthesis and for which experimental results are now available. We present an augmented kinetic scheme and then employ methods of stochastic simulation algorithm to obtain time dependent concentrations of different substances involved in the reaction and their rates of formation. We obtain the rates of product formation and ATP hydrolysis for both correct and wrong substrates (isoleucine and valine in our case, respectively, in single molecular enzyme as well as ensemble enzyme kinetics. The present theoretical scheme correctly reproduces (i the amplitude of the discrimination factor in the overall rates between isoleucine and valine which is obtained as (1.8×10(2.(4.33×10(2 = 7.8×10(4, (ii the rates of ATP hydrolysis for both Ile and Val at different substrate concentrations in the aminoacylation of tRNA(Ile. The present study shows a non-michaelis type dependence of rate of reaction on tRNA(Ile concentration in case of valine. The overall editing in steady state is found to be independent of amino acid concentration. Interestingly, the computed ATP hydrolysis rate for valine at high substrate concentration is same as the rate of formation of Ile-tRNA(Ile whereas at intermediate substrate concentration the ATP hydrolysis rate is relatively low. We find that the presence of additional editing domain in class I editing enzyme makes the kinetic proofreading more efficient through enhanced hydrolysis of wrong product at the editing CP1 domain.

      The potential for imaging the angiotensin II receptor was evaluated using the radioiodinated peptide antagonist [ 125 I][Sar 1 , Ile 8 ]angiotensin II. The radioligand provides a receptor-mediated signal in several tissues in rat (kidneys, adrenal and liver). The receptor-mediated signal of 3% ID/g kidney cortex should be sufficient to permit imaging, at least via SPECT. The radiotracer is sensitive to reductions in receptor concentration and can be used to define in vivo dose-occupancy curves of angiotensin II receptor ligands. Receptor-mediated images of [ 123 I][Sar 1 , Ile 8 ]angiotensin II were obtained in the rat kidney and Rhesus monkey liver. (author)

      2014-03-01

      Full Text Available The present study's objective was to analyze the procedures aimed at guaranteeing sanitary conditions when acquiring meat. The study was conducted with university restaurants of the Federal Institutions of Higher Education (IFES located in the five regions of Brazil. Data were collected using a questionnaire and an evaluation list, which was available online to restaurant professionals. The results showed that restaurants chose one or two types of meat, the most frequent of which were beef and chicken. In restaurants managed by the IFES, the acquisition of raw material occurred by bidding. For vendor selection, the restaurants required product registration with the Inspection Service and requested regulation of the supplier by the Health Surveillance. Monitoring was carried out through a technical visit to the supplier and a review of the past records of the supplier. A higher percentage of restaurants in the Southeast region met appropriate sanitary and hygienic criteria for the receipt of meat, followed by the South, Midwest, Northeast and North. We conclude that restaurants meet most of the safety criteria set in the legislation. However, some weaknesses are evident in the physical and functional structure, the system of transportation of raw material and the records of control measures at the place of reception.

    12. Low cost, high yield IFE reactors: Revisiting Velikhov's vaporizing blankets

      Logan, B.G.

      1992-01-01

      The performance (efficiency and cost) of IFE reactors using MHD conversion is explored for target blanket shells of various materials vaporized and ionized by high fusion yields (5 to 500 GJ). A magnetized, prestressed reactor chamber concept is modeled together with previously developed models for the Compact Fusion Advanced Rankine II (CFARII) MHD Balance-of-Plant (BoP). Using conservative 1-D neutronics models, high fusion yields (20 to 80 GJ) are found necessary to heat Flibe, lithium, and lead-lithium blankets to MHD plasma temperatures, at initial solid thicknesses sufficient to capture most of the fusion yield. Advanced drivers/targets would need to be developed to achieve a ''Bang per Buck'' figure-of-merit approx-gt 20 to 40 joules yield per driver $ for this scheme to be competitive with these blanket materials. Alternatively, more realistic neutronics models and better materials such as lithium hydride may lower the minimum required yields substantially. The very low CFARII BoP costs (contributing only 3 mills/kWehr to CoE) allows this type of reactor, given sufficient advances that non-driver costs dominate, to ultimately produce electricity at a much lower cost than any current nuclear plant

      Full Text Available Worldwide the mosquito Aedes aegypti (L. is the principal urban vector of dengue viruses. Currently 2.5 billion people are at risk for infection and reduction of Ae. aegypti populations is the most effective means to reduce the risk of transmission. Pyrethroids are used extensively for adult mosquito control, especially during dengue outbreaks. Pyrethroids promote activation and prolong the activation of the voltage gated sodium channel protein (VGSC by interacting with two distinct pyrethroid receptor sites [1], formed by the interfaces of the transmembrane helix subunit 6 (S6 of domains II and III. Mutations of S6 in domains II and III synergize so that double mutants have higher pyrethroid resistance than mutants in either domain alone. Computer models predict an allosteric interaction between mutations in the two domains. In Ae. aegypti, a Ile1,016 mutation in the S6 of domain II was discovered in 2006 and found to be associated with pyrethroid resistance in field populations in Mexico. In 2010 a second mutation, Cys1,534 in the S6 of domain III was discovered and also found to be associated with pyrethroid resistance and correlated with the frequency of Ile1,016.A linkage disequilibrium analysis was performed on Ile1,016 and Cys1,534 in Ae. aegypti collected in Mexico from 2000-2012 to test for statistical associations between S6 in domains II and III in natural populations. We estimated the frequency of the four dilocus haplotypes in 1,016 and 1,534: Val1,016/Phe1,534 (susceptible, Val1,016/Cys1,534, Ile1,016/Phe1,534, and Ile1,016/Cys1,534 (resistant. The susceptible Val1,016/Phe1,534 haplotype went from near fixation to extinction and the resistant Ile1,016/Cys1,534 haplotype increased in all collections from a frequency close to zero to frequencies ranging from 0.5-0.9. The Val1,016/Cys1,534 haplotype increased in all collections until 2008 after which it began to decline as Ile1,016/Cys1,534 increased. However, the Ile1,016/Phe1

      There are some mechanism to commercialize the innovations that have been developed by academic scientists in universities, i.e. patenting, licensing, start-up creation, and university-industry partnerships. The start-up creations or university spin-offs (USOs) company is a very special start-up company that is founded by an academic inventor and the university with the aim to commercialize the technological innovation that created by the university. However, it is not always as smooth as expected. The market competitiveness of the USOs obviously has many challenges to be able to compete with the existing companies, analysis need to be done to get the right business step so the business strategy will be efficient. In this article, we discuss a real case study of a university spin-off that owned by Sebelas Maret University for Commercializing Battery Lithium. The aim of our research is twofold: first, to identify the gap in the literature of business strategy formulation between a conventional and USOs. Second, to propose a business strategy formulation for commercializing university-created technology, i.e. battery lithium as core business of a university spin-off as a case study. We conduct surveys, observation and FGD in order to collect the data and information to build the company objective and goals. The analytical tools to generate the solution of business strategy are SWOT analysis, IFE-EFE matrix, and QSPM model so the result will be the most attractive and suitable for the company. The result shows that the case study of USO company is classified on conservative continuous improvement phase so the suitable strategy for this company are product development and business strategy integration.

    15. Systems modeling for a laser-driven IFE power plant using direct conversion

      International Nuclear Information System (INIS)

      Meier, W R

      2008-01-01

      A variety of systems analyses have been conducted for laser driver IFE power plants being developed as part of the High Average Power Laser (HAPL) program. A key factor determining the economics attractiveness of the power plant is the net power conversion efficiency which increases with increasing laser efficiency, target gain and fusion-to-electric power conversion efficiency. A possible approach to increasing the power conversion efficiency is direct conversion of ionized target emissions to electricity. This study examines the potential benefits of increased efficiency when the expanding plasma is inductively coupled to an external circuit allowing some of the ion energy to be directly converted to electricity. For base case direct-drive targets with approximately 24% of the target yield in ions, the benefits are modest, especially for chamber designs that operate at high temperature and thus already have relatively high thermal conversion efficiencies. The reduction in the projected cost of electricity is ∼5-10%

      The heat capacities of two kinds of rare-earth element solid complexes with isoleucine [Re 2 (Ile) 4 (H 2 O) 8 ](ClO 4 ) 6 (where Re=Nd, Er, and Ile=isoleucine) have been measured by an automatic adiabatic calorimeter in the temperature range from 80 to 370 K. Two solid-solid phase transitions were found from the C p curve of Nd formed complex in the range of 165-175 K with a peak temperature of 167.88 K and in the range of 195-210 K with a peak temperature of 202.13 K. The corresponding molar enthalpies of these phase transitions were determined to be 404.61 J mol -1 and 2.955 kJ mol -1 , respectively. One solid-solid phase transition was found for the Er formed complex in the range of 190-205 K with a peak temperature of 193.42 K. The corresponding molar enthalpy of this transition was 14.11 kJ mol -1 . Smooth heat capacities and thermodynamic functions relative to the standard state (298.15 K), H T -H 298.15 , S T -S 298.15 and -[G T -G 298.15 ], of the two compounds, were calculated on basis of experimental heat capacity data.

      Full Text Available Brain Fag Syndrome (BFS is a psychiatric disorder associated with study affecting two to four out of every ten African students. One of the consequences of this illness is early foreclosure of education in affected students. Etiological factors such as nervous predisposition, motivation for achievement, and psycho-stimulant use have been found associated with it. However, the contributions of study habits to the pathogenesis of this study-related illness deserve more attention than has been given. We carried out this cross-sectional study to ascertain the types of study habits associated with BFS among a sample of senior secondary school students in Ile-Ife, Nigeria. Five hundred students from six schools in Ile-Ife were selected using a stratified random sampling technique. The selected students completed the Socio-demographic Data Schedule, the Brain Fag Syndrome Scale, and Bakare’s Study Habit Inventory. The prevalence of BFS was 40.2% (201. There were no significant socio-demographic variables identifying BFS students apart from those without BFS. The significant measures of study habits that predicted BFS were homework and assignments, examinations, and written work. Those with BFS had 3.58 times the odds to perform poorly on homework and assignments, 3.27 times the odds to perform poorly on examinations, and 1.01 times the odds to perform poorly on written work compared to those without BFS. We concluded that the results of this study suggest that homework and assignments, examinations, and written work were significant study habit variables associated with BFS.

    2. The HYLIFE-II inertial fusion energy power plant concept and implications for IFE

      International Nuclear Information System (INIS)

      Moir, R.W.

      1994-01-01

      HYLIFE-II is based on nonflammable, renewable-liquid-wall fusion target chambers formed with Li 2 BeF 4 molten-salt jets, a heavy-ion driver, and single-sided illumination of indirect-drive targets. Building fusion chambers from existing materials with life-of-plant structural walls behind the liquid walls, while still meeting non-nuclear grade construction and low-level waste requirements, has profound implications for IFE development. Fluid-flow work and computational fluid dynamics predict chamber clearing adequate for 6-Hz pulse rates. Predicted electricity cost is reduced about 30% to 4.4 cents/kWh at 1 GWe. Development can be foreshortened and cost reduced by obviating expensive neutron sources to develop first-wall materials. The driver and chamber can be upgraded in stages, avoiding separate and sequential facilities. The most important features of a practical inertial fusion power plant are sufficient ignition and gain in targets; a low-cost, efficient, rep-ratable driver; and low-cost targets

    3. A case-control study of the HER2 Ile655Val polymorphism in relation to risk of invasive breast cancer

      2005-01-01

      Overexpression of the HER2 proto-oncogene in human cancer cells has been associated with a poor prognosis, and survival improves with therapy targeting the HER2 gene. Animal studies and protein modeling suggest that the Ile655Val polymorphism located in the transmembrane domain of the HER2 protein might influence breast cancer development by altering the efficiency of homodimerization. To investigate this genetic polymorphism, incident cases of invasive breast cancer (N = 1,094) and population controls of a similar age (N = 976) were interviewed during 2001 to 2003 regarding their risk factors for breast cancer. By using DNA collected from buccal samples mailed by the participants, the HER2 Ile655Val polymorphism was evaluated with the Applied Biosystems allelic discrimination assay. Odds ratios (ORs) and 95% confidence intervals (95% CIs) were estimated by logistic regression adjusted for numerous breast cancer risk factors. Analysis was restricted to women with self-reported European descent. Prevalence of the Val/Val genotype was 5.6% in cases and 7.1% in controls. In comparison with the Ile/Ile genotype, the Ile/Val genotype was not significantly associated with breast cancer risk (OR 0.97, 95% CI 0.79 to 1.18), whereas the Val/Val genotype was associated with a reduced risk (OR 0.63, 95% CI 0.42 to 0.92). This inverse association seemed strongest in older women (OR 0.51, 95% CI 0.29 to 0.89 for women aged more than 55 years), women without a family history of breast cancer (OR 0.54, 95% CI 0.35 to 0.84), postmenopausal women with greater body mass index (OR 0.43, 95% CI 0.20 to 0.91 for a body mass index of 25.3 kg/m 2 or more), and cases diagnosed with non-localized breast cancer (OR 0.49, 95% CI 0.26 to 0.90). Although results from our population-based case-control study show an inverse association between the HER2 Ile655Val polymorphism and risk of invasive breast cancer, most other studies of this single-nucleotide polymorphism suggest an overall null

      Moir, R.; Morley, N.

      1999-01-01

      For some time now people have thought of liquid walls as an attractive solution to the technology problems of high power density plasma configurations for MFE, and as (nearly) essential for the pulsed wall-loading conditions in IFE. A flowing, renewable surface could be eroded, evaporated and even be broken apart with no permanent adverse effects on a structure requiring frequent maintenance and replacement. Alpha particle energy could be removed without conduction through a solid wall and the associated thermal stress and creep failure modes, and the energy could be extracted at high temperatures for efficient energy conversion. If a liquid wall of sufficient depth could be formed, radiation damage and waste disposal issues for solid structures could be significantly ameliorated. All these benefits are indeed possible, if only liquid walls could be made to work. As we will see, there are many issues associated with the successful and attractive implementation of liquid walls

      The primary purpose of the workshop was to gather input from the inertial confinement fusion (ICF) laboratories, private industry, and universities on the potential use of the NIF to conduct experiments in support of the development of IFE. To accomplish this, we asked the over 60 workshop participants to identify key credibility and development issues for IFE in four areas Target Physics --Issues related to the design and performance of targets for IFE; Chamber Dynamics -- Issues in IFE chambers resulting from the deposition of x-rays and debris; Inertial Fusion Power Technology -- Issues for energy conversion, tritium breeding and processing, and radiation shielding; interactions of neutrons with materials; and chamber design; Target System -- Issues related to automated, high-production-rate manufacture of low-cost targets for IFE, target handling and transport, target injection, tracking, and beam pointing. These topics are discussed in this report

      A comprehensive assessment on the eligibility of reduced activation (RA) steels as structural chamber material in Inertial Fusion Energy (IFE) thick-liquid concepts is performed. As far as alloying elements, it is shown that the activation of tungsten is a question to debate. Regarding impurity elements, it is analyzed if they could question the possibility of obtaining real RA steels for shallow land burial (SLB). The effect of the thickness of the liquid wall on the SLB response of alloying and impurity elements is computed. And above all, we have estimated the impact of cross section uncertainties when addressing the former questions, and we identify those to be improved. The necessary improvement of some tungsten and niobium cross sections is justified.

A first part analyses the treatment offer and actual health care for radiotherapy in the region: supply mapping (in terms of centres, medical and technical personnel), and analysis of patient flows in 2009 and 2010. It outlines challenges and formulates recommendations for an offer reorganisation by analysing the present access to radiotherapy offer, and by discussing a desirable offer in radiotherapy

    13. methanization development in Ile-de-France - Ile-de-France region. Synthesis. The Regional Council strategy for methanization development

      International Nuclear Information System (INIS)

      2013-06-01

      A first document reports the study of methanization development in the Ile-de-France region by addressing biomass produced on the region territory. It aimed at identifying and assessing the existing and potential physical resource while introducing mobilisation rates in order to define different scenarios. A situational analysis of operated and projected methanization installations has also been performed. These projects have been classified according to a typology, and analysed according to the proposed scenarios. The position of methanization with respect to other biomass valorisation sectors, as well as the impact of mobilisation with respect to a return-to-soil of organic matters have also been discussed. A second document proposes a synthetic version of this study. The third document presents the Regional Council's policy and strategy regarding methanization development: challenges and prospective scenarios, importance of a sustainable methanization at the service of territory development, regulation for a call for projects, project assessment and selection, project footprint, inputs qualities and supplies, energetic and agronomic valorisation, and grid for project analysis. An appendix contains a synthetic version of the first document

      Michael Olusesan Awoleye

      2008-04-01

      Full Text Available This study focused on the level of penetration of Internet usage among undergraduate students in Nigeria using Obafemi Awolowo University as a case study. Result showed that about 92% of undergraduate students have embraced the Internet and are using it consistently. The online mean time is 3.5hrs/week while on the average, undergraduate experience of Internet usage is about 4years. We found also that the students use the Internet mostly for e-mail, information search and online chatting; all of these were found to have significant impact on their academics and social life. Further analysis revealed that gender attitude is also an important issue; male students appear to use the Internet more than their female counterparts; just as science based students use it more than the non-science based students. The paper therefore recommends appropriate policies for all higher schools of learning in Nigeria to facilitate further diffusion and use of the Internet.

      Multiple sclerosis (MS) is an inflammatory neurodegenerative disease of the nervous system with a profound genetic element. It is already known that alterations in Eukaryotic Translation Initiation Factor 2B (EIF2B) gene encoding the five subunits of eIF2B complex cause Vanishing White Matter (VWM) disease of the brain and emerging evidences have advocated certain resemblances between MS and VWM in terms of clinical and epidemiological characteristics, thus validating the association study between EIF2B and MS. Moreover, a recent study has implicated EIF2B5 Ile587Val (rs843358) polymorphism as a susceptibility factor for MS. In order to investigate the association of EIF2B5 Ile587Val polymorphism with MS susceptibility in Kashmir region in India, we screened EIF2B5 Exon 13 in 30 MS patients and 65 controls (a total of 95 participants). During the present course of study, we could not find statistically significant difference in the frequency of Ile587Val between MS patients and controls, thus indicating that such alteration does not appear to influence MS development in Kashmiri population. Our results provide evidence against a major role for Ile587Val polymorphism in MS susceptibility. Copyright © 2015 Elsevier B.V. All rights reserved.

    19. Recent improvements in PIE-techniques at the IFE hot-laboratory

      International Nuclear Information System (INIS)

      Jenssen, Haakon Kristian

      1999-01-01

      The PIE-techniques at the IFE nuclear fuel section are continuously improved through upgrading of equipment and methods, e.g. image handling techniques and components utilised in data acquisition and editing techniques. To improve the quality or spatial resolution of neutron radiographs the normal technique was complemented with another method. The dysprosium foil/X-ray film technique is now supplemented with a track-etch recorder consisting of a cellulose nitrate film. For further examination the cellulose nitrate film can be digitised to allow electronic image treatment. Promising results were obtained with this technique on neutron radiographs, namely higher spatial resolution compared to the normal technique, high contrast and sharp neutron radiography images. The traditional one-axial profilometry of fuel rods were modified so that diameter/bow measurements are possible at several angular orientations during one acquisition sequence. This extension is very useful in several ways, for instance the built-in data symmetry of the method is used to check the correctness of the measurement results. Diameter and bow measurements give in addition detailed and complete information of canning irregularities and fuel rod profiles. PIE data are collected and compiled in an image file. Inspection and examination of the file information is possible through an ideal user-interface, i.e. Adobe photoshop software with navigator possibilities. An example incorporating PIE data acquired from a fuel rod exposed in a loss of coolant experiment is utilised for illustration of the user-interface and some of its possibilities (author) (ml)

    20. Conduction block and tonic pupils in Charcot-Marie-Tooth disease caused by a myelin protein zero p.Ile112Thr mutation.

      Murphy, Sinéad M

      2011-03-01

      We report a patient with Charcot-Marie-Tooth disease (CMT) due to the p.Ile112Thr mutation in myelin protein zero (MPZ) who presented with a patchy neuropathy with conduction block and tonic pupils. Conduction block is unusual in inherited neuropathies, while pupil abnormalities are recognised to occur in CMT especially due to MPZ mutations. This case highlights that patchy demyelinating neuropathy with conduction block may occur in p.Ile112Thr MPZ mutations. Involvement of the pupils, as in this case, may be a pointer towards a genetic rather than inflammatory cause of neuropathy.

      Toll-like receptor-4 (TLR4) polymorphisms may influence host immune response against Helicobacter pylori (H. pylori). This study aimed to investigate whether TLR4 polymorphisms are associated with H. pylori susceptibility and risk of peptic ulcer development or not. The TLR4 + 3725 G/C polymorphism was studied using polymerase chain reaction with confronting two-pair primers (PCR-CTPP). In addition, TLR4 Asp299Gly and Thr399Ile polymorphisms were evaluated by PCR-restriction fragment length polymorphism (RFLP). There was no significant difference in TLR4 + 3725 G/C and Asp299Gly genotype frequencies between non-peptic ulcer (NPUD) and peptic ulcer (PUD) individuals in the context of peptic ulcer development and susceptibility to infection with H. pylori. Nevertheless, a significant association with increased risk for PUD development was observed for polymorphism TLR4 Thr399Ile [odds ratio (OR) = 4.2; 95% confidence interval (CI) = 1.35-13.26; p = 0.01]. Correspondingly, TLR4 Thr399Ile polymorphism was associated with H. pylori susceptibility (OR = 0.27; 95% CI = 0.08-0.88; p = 0.04). In addition, TLR4 Thr399Ile polymorphism increased 4.2-fold, the risk of peptic ulcer development in individuals infected by H. pylori carrying CT + TT genotype. Our results showed that TLR4 Thr399Ile polymorphism along with H. pylori infection may play critical roles in peptic ulcer development in North of Iran. © 2017 APMIS.

    8. Improving radiotherapy quality and safety: a common objective of A.S.N. and the Ile de France Regional Hospital Agency. Thoughts on successful cooperation in Ile de France

      International Nuclear Information System (INIS)

      Solier, N.

      2009-01-01

      Radiotherapy recent development in cancer treatment needs strong procedures and quality assessment to improve safety both for patients and professionals. In Ile de France territory, a coordinated action between ASN inspectors and medical doctors specialized in public health (MISP), working as civil servants in health administration, was initiated at the end of 2007. An inspection guideline was implemented in a workshop between ASN and Regional Hospital Agency (ARH). The MISP as health administrator has to verify if care organisation responds to treatment cancer regulatory framework: as a doctor he is authorized to access to patient records to know which treatment was chosen. He has to assure if the therapeutic guidelines are respected. His comprehensive approach is essentially patient-oriented. The MISP inspection coordinated with ASN inspectors is a very pertinent pluri-disciplinary approach, undeniably necessary in such a medical technic. The effectiveness of the radiotherapy pluri-disciplinary team is funded on sharing procedures and experiences, respecting different knowledge and practices in daily work. This on site audit'. seems to be very fertile both for the radiotherapy team, the MISP and ASN inspectors. Continuous quality improvement in radiotherapy in the Ile de France region is a fertile issue between ANS and ARH teams. Confronting knowledge and procedures during the 'on site audit' in a transparent way will contribute improving radiotherapy for the 30.000 Francilian patients which receive this treatment each year. This challenge is our main concern to facilitate the patients access to the best standards treatments. (author)

      Full Text Available The specific objectives are: i to determine the level of awareness of pesticide residue in locally available food among food sellers in Ile Ife area of Osun state, Nigeria; ii to identify the demographic and socio-economic characteristics of food sellers who use pesticides, natural means in preserving their foodstuff from getting spoilt; iii to determine the level of understanding of food sellers who use pesticides about the likely health implications that could result. The design of the study is cross sectional. Structured open-ended questionnaires were administered to 98 randomly selected food sellers in Ile Ife area Osun state, Nigeria. This includes males and female. The inference from the study shows that majority of the food sellers were between ages 21 and 30 years, suggesting that more of the young people are involved in the selling of foodstuff in the area of study. Most of the food sellers used phostozin, an organophosphate compound as preservatives for cereals. The majority of those that were aware of the health hazards associated with the usage of pesticides as preservative were literate school leavers. Among respondents to the questionnaire, it was expected that many of those food sellers likely to demonstrate caution in the usage of pesticide would be the literate school leavers. This is because they are more aware of the possible associated health hazards than their fellow food sellers who are not literate. The level of awareness of health implications associated with use of pesticides on consumable food items is higher among school certificate holders who are food sellers. Phostozin, an organophosphate, is a common preservative pesticide used on cereals foodstuff (e.g., bean, rice, maize in the area of study, especially among the age group between 21 and 30 years.

    12. Water balance of a small catchment with permeable soils in Ile-Ife area, southwester Nigeria

      International Nuclear Information System (INIS)

      Ogunkoya, O. O.

      2000-01-01

      Three - year and annual catchment water balances were drawn for a small l catchment (44 ha.) in southwestern Nigeria. The equation: P - Q - E T - Δs = O was not resolved. Rather, the terms on the left did not sum to zero. The residual, which are between 4% and 5% of total rainfall, were consistently negative. A probable source of error is the use of Thornthwaite's potential evaporation in estimating catchment evapotranspiration. Potential evapotranspiration is higher than actual evapotranspiration in the study area due to the limited evaporation opportunity during the approximately five - mouth dry season. Given that the study catchment had runoff patterns that are simi liar to those of larger rivers in the region the computed catchment water balance indicated that 37% of annual rainfall may be taken as the runoff coefficient for the region. This suggests that the engineer's coefficient (0.35 - 0.45) used in assessment of surface water resources in southwestern Nigeria, is reasonable

      The following has been achieved: (1) Final design of a Deformable Grazing Incidence Mirror, (2) Formulation of a new approach to model surface roughening under laser illumination, and (3) Modeling of radiation hardening under IFE conditions. We discuss here progress made in each one of these areas. The objectives of the Grazing Incidence Metal Mirror (GIMM) are: (1) to reflect the incident laser beam into the direction of the target; (2) to focus the incident beam directly onto the target (3) to withstand the thermomechanical and damage induced by laser beams; (4) to correct the reflective surface so that the focus is permanently on the target; (5) to have a full range of motion so it can be placed anywhere relative to the target. The design was described in our progress report of the period August 15, 2003 through April 15, 2004. In the following, we describe further improvements of the final design.

      Full Text Available Abstract Von Hippel-Lindau disease (VHL is a rare autosomal dominant disease characterized by development of cystic and tumorous lesions at multiple sites, including the brain, spinal cord, kidneys, adrenals, pancreas, epididymis and eyes. The clinical phenotype results from molecular abnormalities of the VHL tumor suppressor gene, mapped to human chromosome 3p25-26. The VHL gene encodes two functionally active VHL proteins due to the presence of two translational initiation sites separated by 53 codons. The majority of disease-causing mutations have been detected downstream of the second translational initiation site, but there are conflicting data as to whether few mutations located in the first 53 codons, such as the Pro25Leu could have a pathogenic role. In this paper we report a large Hungarian VHL type 2 family consisting of 32 members in whom a disease-causing AGT80AAT (Ser80Ile c.239G>A, p.Ser80Ile mutation, but not the concurrent CCT25CTT (Pro25Leu c.74C>T, p.Pro25Leu variant co-segregated with the disease. To our knowledge, the Ser80Ile mutation has not been previously described in VHL type 2 patients with high risk of pheochromocytoma and renal cell cancer. Therefore, this finding represents a novel genotype-phenotype association and VHL kindreds with Ser80Ile mutation will require careful surveillance for pheochromocytoma. We concluded that the Pro25Leu variant is a rare, neutral variant, but the presence such a rare gene variant may make genetic counseling difficult.

      Full Text Available Researches have been carried out in the past by several authors concerning agricultural marketing without the use of geospatial techniques. This research therefore is meant to show the efficacy of Geographical Information System GIS in local market distribution. The role of market place as a man-made feature where goods and services are exchanged for the purpose of satisfying human needs cannot be overemphasized especially in the general development of villages and towns. This study shows the effectiveness of GIS without the use of metrics method to determine the agricultural market locations and closeness of the markets in Ife North Local Government area. Different kinds of people bring their goods from far and near villages for sale and sustainability in this research both primary and secondary data were collected. Primary data includes the use of Global Positioning System GPS receiver to collect coordinate points of the existing markets. It also involves verbal interview with market women. While secondary data were sourced from administrative maps and satellite images of the area of study it was geo-referenced and digitized. Arc Map was used to run average nearest neighbor analysis. Base on the analysis performed the major constraint facing the market people is poor road network which affect majority of the farmers in transporting their goods from remote villages as indicated in this study. As a result new markets sites were proposed with the use of geospatial techniques for easy accessibility.

      The heat capacities of two kinds of rare-earth element solid complexes with isoleucine [Re{sub 2}(Ile){sub 4}(H{sub 2}O){sub 8}](ClO{sub 4}){sub 6} (where Re=Nd, Er, and Ile=isoleucine) have been measured by an automatic adiabatic calorimeter in the temperature range from 80 to 370 K. Two solid-solid phase transitions were found from the C{sub p} curve of Nd formed complex in the range of 165-175 K with a peak temperature of 167.88 K and in the range of 195-210 K with a peak temperature of 202.13 K. The corresponding molar enthalpies of these phase transitions were determined to be 404.61 J mol{sup -1} and 2.955 kJ mol{sup -1}, respectively. One solid-solid phase transition was found for the Er formed complex in the range of 190-205 K with a peak temperature of 193.42 K. The corresponding molar enthalpy of this transition was 14.11 kJ mol{sup -1}. Smooth heat capacities and thermodynamic functions relative to the standard state (298.15 K), H{sub T}-H{sub 298.15}, S{sub T}-S{sub 298.15} and -[G{sub T}-G{sub 298.15}], of the two compounds, were calculated on basis of experimental heat capacity data. Possible mechanisms of thermal decompositions for the pair of compounds were suggested according to the thermogravimetric (TG) analysis.

      The Heavy Ion Fusion Science Virtual National Laboratory (HIFS-VNL) is currently developing design concepts for NDCX-II, the second phase of the Neutralized Drift Compression Experiment, which will use ion beams to explore Warm Dense Matter (WDM) and Inertial Fusion Energy (IFE) target hydrodynamics. The ion induction accelerator will consist of a new short pulse injector and induction cells from the decommissioned Advanced Test Accelerator (ATA) at Lawrence Livermore National Laboratory (LLNL). To fit within an existing building and to meet the energy and temporal requirements of various target experiments, an aggressive beam compression and acceleration schedule is planned. WDM physics and ion-driven direct drive hydrodynamics will initially be explored with 30 nC of lithium ions in experiments involving ion deposition, ablation, acceleration and stability of planar targets. Other ion sources which may deliver higher charge per bunch will be explored. A test stand has been built at Lawrence Berkeley National Laboratory (LBNL) to test refurbished ATA induction cells and pulsed power hardware for voltage holding and ability to produce various compression and acceleration waveforms. Another test stand is being used to develop and characterize lithium-doped aluminosilicate ion sources. The first experiments will include heating metallic targets to 10,000 K and hydrodynamics studies with cryogenic hydrogen targets

      When a nuclear accident has occurred, intervention teams have to work out the actions in order to limit results of accident on personnel, installations and environment. Initial stage, that begin applying special cards, allows to organize command and rescue, and brings intervention teams on the accident site. Intervention is composed of three stages: victims' rescue, struggle against conflagration, and technical support to the damaged structure. The diversity of teams allows to carry out these operations at the same time. According as personnel is injured or able bodied, decontamination is carried out in specific structure. Victims' rescue is a priority. Casualties are treated in the Ile Longue treatment center of technical shelters (CTBRC/ETNI). Able-bodied people in the area of accident have to reach refuges immediately after the alarm. They are presumed contaminated and first are checked in the advanced command station. Then they are evacuated, after a stage station, to the large capacity decontamination and triage center, where treatment and control can be effectuated; the evacuation is now possible. Some of them are treated in the Ile Longue contamination treatment center in case of internal or obstinate contamination. (author)

      , low electrical conductivity and therefore low MHD pressure drop, low chemical reactivity, and extremely low tritium inventory; the addition of sodium (FLiNaBe) has been considered because it retains the properties of FliBe but also lowers the melting point. Although many of these blanket concepts are promising, challenges still remain. The limited amount of beryllium available poses a problem for ceramic breeders such as the HCPB. FLiBe and FLiNaBe are highly viscous and have a low thermal conductivity. Lithium lead possesses a poor thermal conductivity which can cause problems in both DCLL and LiPb blankets. Additionally, the tritium permeation from these two blankets into plant components can be a problem and must be reduced. Consequently, Lawrence Livermore National Laboratory (LLNL) is attempting to develop a lithium-based alloy—most likely a ternary alloy—which maintains the beneficial properties of lithium (e.g. high tritium breeding and solubility) while reducing overall flammability concerns for use in the blanket of an inertial fusion energy (IFE) power plant. The LLNL concept employs inertial confinement fusion (ICF) through the use of lasers aimed at an indirect-driven target composed of deuterium-tritium fuel. The fusion driver/target design implements the same physics currently experimented at the National Ignition Facility (NIF). The plant uses lithium in both the primary coolant and blanket; therefore, lithium-related hazards are of primary concern. Although reducing chemical reactivity is the primary motivation for the development of new lithium alloys, the successful candidates will have to guarantee acceptable performance in all their functions. The scope of this study is to evaluate the neutronics performance of a large number of lithium-based alloys in the blanket of the IFE engine and assess their properties upon activation. This manuscript is organized as follows: Section 12 presents the models and methodologies used for the analysis; Section

      Full Text Available Abstract. A comparative analysis of amino acid composition of lamb meat from the North East Bulgarian fine fleece breed (I gr. and its crossbreds from internal breeding with 25% heredity from the Australian merino (II gr. and Ile de France (III gr. breeds was conducted. Upon starting the experiment lambs were equal and during the experiment they were placed under similar conditions of feeding and rearing. To establish the amino acid composition of meat slaughter analyses were performed at 100 and 130 days of age. From the carcass of each slaughtered animal individual mean samples were taken. Studies were carried out in the Research Laboratory of the Faculty of Agriculture at Trakia University. As a result of the studies the following conclusions were made: ¼ Ile de France crossbreds in a sophisticated crossing have the highest total amino acid content, including essential amino acids in the meat of 100- and 130-day-old lambs, 6.87% and 7.36%, respectively. The lysine/arginine ratio, relating to protein atherogenicity, varies within narrow ranges among groups and marks slight increase with age – from 1.31-1.37 at 100 days to 1.41-1.46 at 130 days. With the increase of age in crossbreds from internal breeding total protein amino acid content grows, that being most prominent in lambs from the III group – from 41.92 to 43.49%. The values of total protein indices increase compared to the reference protein (from 117.97% to 118.22% for II group and from 116.44% to 120.80% for III group and the whole egg protein (from 89.39% to 91.92% for II group and from 90.53% to 93.93 for III group. It has been found that internal breeding of crossbreds with 25% heredity from the Ile de France breed has positive effect concerning the total amino acid content of lamb meat at 100 and 130 days of age, essential amino acid content in it and the levels of total amino acid indices.

      Atmospheric aerosols interact directly in a great number of processes related to climate change and public health, modifying the energy budget and partly determining the quality of the air we breathe. In my PhD, I chose to study the perturbation, if not the aggravation, of the living conditions in Ile-de-France associated to aerosol transport episodes in the free troposphere. This situation is rather frequent and still badly known. To achieve my study, I developed the observation platform 'TReSS' Transportable Remote Sensing Station, whose instruments were developed at the Laboratoire de Meteorology Dynamique by the LiMAG team. 'TReSS' consists of a new high-performance 'Mini-Lidar' and of two standard radiometers: a sun photometer and a thermal infrared radiometer. The principle of my experimental approach is the synergy of the vertical Lidar profiles and the particle size distributions over the column, obtained by the 'Almucantar' inversion of sun photometer data. The new 'Lidar and Almucantar' method characterizes the vertical distribution by layer and the optical micro-physical properties of the local and transported aerosols. Firstly, I undertook the characterization of the Paris aerosol, mainly of anthropogenic origin. Their radiative properties were analyzed in the daily and yearly scales. Then, I conducted a statistical multi-year study of transport episodes and a two-week study case, representative of a succession of desert dust intrusion in Ile-de-France. My PhD work concludes by a study on the impact of biomass burning aerosols during the heat wave on August 2003. I study the impact of the transported aerosols into the local radiative budget and the possible consequences on the diurnal cycle of the atmospheric boundary layer. (author)

      There has been rapid progress in inertial fusion in the past few years. This progress spans the construction of ignition facilities, a wide range of target concepts and the pursuit of integrated programmes to develop fusion energy using lasers, ion beams and z-pinches. Two ignition facilities are under construction, the national ignition facility (NIF) in the United States and the laser megajoule (LMJ) in France, and both projects are progressing towards an initial experimental capability. The laser integration line prototype beamline for LMJ and the first four beams of NIF will be available for experiments in 2003. The full 192 beam capability of NIF will be available in 2009 and ignition experiments are expected to begin shortly after that time. There is steady progress in target science and target fabrication in preparation for indirect-drive ignition experiments on NIF. Advanced target designs may lead to 5 10 times more yield than initial target designs. There has also been excellent progress on the science of ion beam and z-pinch-driven indirect-drive targets. Excellent progress on direct-drive targets has been obtained on the Omega laser at the University of Rochester. This includes improved performance of targets with a pulse shape predicted to result in reduced hydrodynamic instability. Rochester has also obtained encouraging results from initial cryogenic implosions. There is widespread interest in the science of fast ignition because of its potential for achieving higher target gain with lower driver energy and relaxed target fabrication requirements. Researchers from Osaka have achieved outstanding implosion and heating results from the Gekko XII Petawatt facility and implosions suitable for fast ignition have been tested on the Omega laser. A broad-based programme to develop lasers and ion beams for inertial fusion energy (IFE) is under way with excellent progress in drivers, chambers, target fabrication and target injection.

      The level of air pollution around the automobile mechanic workshops has been generally overlooked. This study, examined the level of trace metals in automobile mechanic workshops and the suitability of using transplanted lichen thalli of Lepraria incana for measuring air pollution in such areas. Samples of the lichen thalli were transplanted into seven different sites and were attached to the bark of trees at each site. The samples were harvested from the sites after 3-month exposure. Concentrations of Pb, Cu, Cd, Fe, Zn, and S content were determined using an atomic absorption spectrophotometer. Results showed that there was a significant difference in the trace metals concentrations across the sites (p trend in the concentration of these heavy metals suggests that activities in these workshops might become a major source of certain heavy metals in the environment and if the pollution activities persist, it might become worrisome over time.

      Full Text Available Background: Disturbances of menstrual bleeding are major social and medical problem for women and account for high percentage of gynecological visit. Objectives: The objective of the study was to document menstrual abnormalities experienced by female college students, their awareness and health seeking behavior. Materials and Methods: A cross-sectional survey was undertaken, 400 students were selected using stratified sampling technique and interviewed using semi-structured self-administered questionnaire. Inferential statistical analysis such as Chi-square test and logistic regressions were carried out. Results: The mean age at menarche was 14.18 years. Irregular menstrual cycles were reported in 9.0%. Dysmenorrhea was present in 62.5%, and 12.5% reported school absenteeism. Students′ awareness of menstrual abnormalities was poor (29%. A few of them (10.5% decided to seek help for menstrual abnormalities. The awareness of students on menstrual abnormalities was significantly influenced by their age (OR = 2.33, P = 0.03; however, age at menarche and level of study did not influence their awareness (OR = 0.45, P = 0.24 and OR = 1.42, P = 0.12. History of dysmenorrheal (OR = 10.2, P = 0.001 and academic disturbance (OR = 5.45, P = 0.001 had significant influence on the health seeking behavior of the students. Conclusion: There was a general lack of information about menstrual issues and when to seek help. There is a need to educate female college students about menstrual issues in order to improve their health seeking behavior as regards menstrual abnormalities.

      Full Text Available This study aimed to understand, critically, as is characterized the participative management on IFES – Campus Serra, from the understanding and the interactive process of the administrative technicians staff (TAEs classes C, D and E and immediate supervisors. Thus, Jürgen Habermas's Communicative Action Theory (CAT, as well as its proposal for democracy deliberative, were undertaken as a theoretical framework for understanding this process. This work is characterized as a qualitative research and has a critical approach with dialectical view of social reality. Empirical data were produced by desk research, participant observation and semi-structured interviews. The content analysis was used for the treatment of interview. The results point to the construction of participatory actions of instrumental nature, established based on the interests of the management of specific and individual groups. Thus, the practice of participative management is characterized as a strategic space to reach the success and not the understanding, where the TAEs share the responsibility in the process of maintenance and construction of the phenomena that hamper the development of democratic participation.

      Apical Periodontitis (AP) is an inflammatory disease that affects the tissues surrounding the root end of a tooth. The disease which is caused by endodontic infections presents in different clinical ways including development of an acute abscess. Recent studies have provided information suggesting role of a multitude of factors in pathogenesis of acute apical abscess (AAA). In this case-control study, our goal was to evaluate the frequency and potential role of two common polymorphisms of toll like receptor-4 (TLR-4) gene; Thr399Ile (1196 C>T) and Asp299Gly (+896 A>G), in 50 patients with AAA as cases and 50 patients with asymptomatic apical periodontitis (AAP) as controls. Saliva sample containing mucosal epithelial cells was used for DNA extraction. Polymorphisms were detected by Tetra-ARMS (Amplification Refractory Mutation System) PCR method. Statistical analyses were carried out in SPSS 21 software. Homozygous wild type (CC) and heterozygous (CT) genotypes of Thr399Ile polymorphism were detected in 84% and 16% of AAA patients respectively. In controls, respective ratios were 94% (CC) and 6% (CT). Observed difference was not statistically significant ( P >0.05) for distribution of these genotypes. The mutant homozygous (TT) genotype of this polymorphism was identified in neither of the participants. Overall, T allele frequency was obtained 8% in AAA and 3% in AAP (OR=2.6, 95% CI; 0. 6-10.6, p >0.05). For Asp299Gly polymorphism, no individual was detected with the mutant allele in case or control groups. Our results indicated a possible role for Thr399Ile polymorphism in acute presentations of abscess in AAA. However, the impact of this polymorphism needs to be more assessed in future studies. Key words: Genetic polymorphism, periapical abscess, periapical periodontitis, toll-like receptor 4.

      Full Text Available Objective: This study aimed to identify certain risky behavior patterns (unsafe sex, tobacco and drug use, and binge drinking and the factors affecting these behaviors among first- and third-year students in a university. Method: The study included a total of 8407 students enrolled as first- (4392 and third- (4015 year students. A self-administered questionnaire was used for data collection. In data analysis, respecting sampling weights, models were formed by logistic regression method to determine factors that affect the risky behaviors. Results: 731 male–1114 female students from the first year and 560 male–1096 female students from the third year were interviewed. Male students were found to be engaged in risky behaviors more frequently than females. Logistic models of the study indicated that gender, place of residence, relationship with parents, and socialization with friends have profound effects on risky behaviors. Conclusion: After leaving home, young people develop their own lifestyles, and this study demonstrates that lifestyle is the main effective factor for risky behaviors in this group. Universities need to assume more responsibility to guide students’ lives and to provide the facilities and opportunities that encourage and facilitate their adoption of a healthy lifestyle.   Key Words: University students, risky behaviours Bir Üniversitede Öğrencilerin Riskli Davranışları: Kesitsel Bir Çalışma Amaç: Bu çalışmanın amacı, bir üniversitenin birinci ve üçüncü sınıf öğrencileri arasında bazı riskli davranış modellerini (güvensiz seks, tütün ve uyuşturucu kullanımı ve aşırı alkol ve bu davranışları etkileyen faktörleri saptamaktır.

      Full Text Available Chronic alcohol consumption leads to the development of specific disorders, particularly of the liver. In this study, we aimed to investigate by optical microscopy the hepatic changes occurring after administration of ethyl alcohol for 70 days to Wistar rats, as well as the curative effect of mineral water from spring 3 in Băile Tuşnad administered for 50 days after completion of ethyl alcohol administration. Liver fragments were harvested and histologically processed by paraffin embedding and stained with Goldner’s trichrome method. After the first 70 days of the experiment, in the liver parenchyma, fat loading of hepatocytes and mild perivascular fibrosis were identified. After another 50 days, during which some of the rats drank tap water, the pathological evolution did not seem to stop, but on the contrary, a slight aggravation could be observed, while in rats drinking Tuşnad mineral water there was an arrest of evolution and a slight regression of the described aspects. This study evidences the curative effect of mineral water from spring 3 in Băile Tuşnad on alcoholic liver disease.

    4. Characterization of atmospheric aerosols in Ile-de-France: Local contribution and Long range transport

      2006-06-01

      Atmospheric aerosols interact directly in a great number of processes related to climate change and public health, modifying the energy budget and partly determining the quality of the air we breathe. In my PhD, I chose to study the perturbation, if not the aggravation, of the living conditions in Ile-de-France associated to aerosol transport episodes in the free troposphere. This situation is rather frequent and still badly known. To achieve my study, I developed the observation platform 'TReSS' Transportable Remote Sensing Station, whose instruments were developed at the Laboratoire de Meteorology Dynamique by the LiMAG team. 'TReSS' consists of a new high-performance 'Mini-Lidar' and of two standard radiometers: a sun photometer and a thermal infrared radiometer. The principle of my experimental approach is the synergy of the vertical Lidar profiles and the particle size distributions over the column, obtained by the 'Almucantar' inversion of sun photometer data. The new 'Lidar and Almucantar' method characterizes the vertical distribution by layer and the optical micro-physical properties of the local and transported aerosols. Firstly, I undertook the characterization of the Paris aerosol, mainly of anthropogenic origin. Their radiative properties were analyzed in the daily and yearly scales. Then, I conducted a statistical multi-year study of transport episodes and a two-week study case, representative of a succession of desert dust intrusion in Ile-de-France. My PhD work concludes by a study on the impact of biomass burning aerosols during the heat wave on August 2003. I study the impact of the transported aerosols into the local radiative budget and the possible consequences on the diurnal cycle of the atmospheric boundary layer. (author)

      Full Text Available The soil seedbank of Tithonia diversifolia, an invasive species which dominates open waste fallowland vegetation was studied. Two different roadside sites which vary in extent of open waste land were selected.The species composition of the established vegetation was assessed in the two diferent sites. Twenty top soil samples were collected at five different distances (15 cm, 30 cm, 45 cm, 60 cm, and 75 cm inwards away from each main road in dry and rainy seasons and the seed bank composition was determined by greenhouse germination over a 6 month period. The similarity between the composition of the seed bank flora and that of the established vegetation was low. The least and the highest emerged seedlings density was recorded in the 15 metres and 75 metres respectively inwards away from the main road in both seasons. The results of the seedlings emergence is a reflection of the extent of open waste land dominated by the invasive species due to human disturbance (road construction on both sites. Overall results suggest that the emergence of the species from the soil seed bank may be due to the impact of the invasive species Tithonia diversifolia on other plant species in the study environment.

      Homosexuality is a recognized risk factor for depression in high-income countries; however, there is little research investigating the relationship between depression and sexual orientation in developing countries, especially in Africa. In this first study to investigate psychopathology in sexual minority men in Nigeria, the prevalence rates of depression in Nigerian gay and heterosexual individuals were compared as well as the explanatory power of risk and resilience factors in both groups. Eighty-one gay and 81 heterosexual male university students were, respectively, recruited from the Obafemi Awolowo University. Both groups were assessed for depression and other clinical factors, including alcohol and other substance use, suicidal ideation, and resilience. Gay students were further assessed for sexuality-related variables, including minority stress factors such as internalized homophobia and perceived stigma. The prevalence rates of depression among gay and heterosexual students were, respectively, 16 and 4.9% (OR 3.7; 95% CI 1.15-11.82), and this increased likelihood for depression was significantly attenuated by resilience. Clinical factors correlated significantly with depression in both groups, explaining 31% of the variance in depression in gay and heterosexual students, respectively. Sexuality-related variables including internalized homophobia and perceived stigma were further associated with depression in gay students-accounting for a further 14% of the variance of depression in gay students. The findings highlight the importance of minority stress factors in understanding depression among non-heterosexual individuals in a developing country, and the need for further research to investigate the mechanisms of these relationships in such settings.

      Inertial fusion ignition, burn and energy gain are expected to be achieved within the first decade of next century with new Megajoule laser facilities which are under construction in the USA and France. Fusion reactor design studies indicate that Inertial Fusion Energy(IFE) power plants are technically feasible and have attractive safety and environmental features. The recent progress on implosion physics and relevant technologies require us to consider a strategic approach toward IFE development. The design study for a laser fusion power plant KOYO has been conducted as a joint program of universities, national laboratories and industries in Japan and also with international collaborations. The progress of high power laser technology gives us feasible project toward a laser driven IFE Power Plant. The technical breakthrough in the field of diode pumped solid state laser (DPSSL) has opened wide application of power laser to industrial technologies. Laser fusion energy development will be proceeded jointly with industrial photonics research and development. International collaborations are also promoted for efficient progress and activation of R and D on advanced technologies which are required for IFE and also useful for modern industries.

      The Ile Grande salt marshes (Brittany coast) were polluted by petroleum hydrocarbons after theAmoco Cadizgrounding in 1978. Thirteen years after the oil spill, sediments were analysed for residual hydrocarbons in order to monitor the aliphatic and aromatic hydrocarbon signatures and to assess both qualitatively and quantitatively the changes in composition of theAmoco Cadizoil. Six stations were selected in the Ile Grande salt marshes and sediments were sampled to a depth of 20 cm. For each sample, the hydrocarbon compositions were determined for alkanes, alkenes, aromatics and biomarkers (terpanes, steranes, diasteranes). Hydrocarbon levels drastically decreased between 1978 and 1991, but to different extents according to the initial degree of contamination. In 1991, hydrocarbon concentrations never exceeded 1·7 g kg-1sediment dry weight, and in most cases were less than 0·1 g kg-1sediment dry weight. Even though petroleum hydrocarbons are still present, natural hydrocarbons were also detected at several stations. Changes in some biomarker distributions were observed 13 years after the oil spill. Nevertheless, most of the biomarkers are very stable in the salt marsh environment and remain unaltered even after a 13-year period.

      Blood transfusion service centers in Nigeria screen donated blood for markers of HIV infection using antibody- (Ab) based rapid test and in some centers, positives are re-tested using Ab-based ELISA. Paucity of data exists on p24 antigen prevalence among HIV Ab-negative donors in Nigeria. This study aims at detecting HIV p24 antigen among prospective blood donors in Osun State, Nigeria. Prospective blood donors negative for HIV antibodies using Determine test kit were re-tested using BIORAD GENSCREEN Ultra Ag-Ab ELISA kit, a fourth-generation ELISA kit that detects HIV antibodies/p24 antigen. Of the 169 HIV Ab-negative prospective donors, 10 (5.9%) were positive for HIV p24 antigen and 70% (7/10) of them were in the age range 18-30 years. Results of this study show that blood transfusion is still one of the major routes of HIV transmission in Nigeria and a higher proportion is among youth. Inclusion of p24 antigen testing into the blood donor screening will help reduce transfusion associated HIV in Nigeria if Nucleic Acid Testing (NAT) of all blood donor samples is not affordable; also, HIV enlightenment programs tailored toward youth may help reduce this rate among donors since more young people donate blood in low/middle-income countries than in high-income countries.

      Full Text Available Gıda sanayiinde yeni yöntemlerin araştırılarak uygulamaya konulması, üretilen gıdaların kalitelerini düzeltmek yönünden olduğu kadar, söz konusu yöntemlerin optimizasyonu açısından da önem taşır. Son 20 yıl içerisinde ilk kez deniz  suyundan içme suyu eldesinde kullanılan ters ozmos yöntemi, gıda sanayiinde yaygın bir uygulama alanı bulmaya başlamıştır. Ters ozmos, bilinen ozmos olayının tersine yönlendirilerek uygulandığı bir yöntemdir. Bu nedenle konunun daha iyi aydınlanması bakımından, canlı metabolizmasında pek çok örnekler görülen ozmos olayının açıklanması gerekir. Bu olayın en basit örneği bir çözelti ile çözücünün yarı geçirgen bir membranla birbirinden ayrıldığı sistemde görülebilir. Bu sistemde şeker çözeltisi ile saf suyun yarı geçirgen bir membranla ayrıldığını düşünecek olursak; çözücüden yani suyun bulunduğu bölümden şeker çözeltisinin bulunduğu ortama doğru bir difüzyon olayı meydana gelecektir. Doğada çok rastlanan bu olaya ozmos olayı adı verilir.

      Full Text Available BACKGROUND: Autosomal dominant non-autoimmune hyperthyroidism (ADNAH is a rare genetic disorder of the endocrine system. Molecular genetic studies in ADNAH have revealed heterozygous germline mutations in the TSHR. To data, mutations leading to an increase in the constitutive activation of the TSHR have been described in the transmembrane segments, exoloops and cytoplasmic loop of TSHR. These mutations result in constitutive activation of the G(αs/cAMP or G(αq/11/inositol phosphate (IP pathways, which stimulate thyroid hormone production and thyroid proliferation. METHODOLOGY/PRINCIPAL FINDINGS: In a previous study, we reported a new TSHR mutation located in the C-terminal domain of TSHR, which results in a substitution of the conserved Ile(691 for Phe. In this study, to address the question of whether the I691F mutated receptor could be responsible for G(αs/cAMP or G(αq/11/IP constitutive activity, wild-type and TSHR mutants were expressed in COS-7 cells to determine cAMP constitutive activity and IP formation. Compared to the cell surface with expression of the A623V mutated receptor as positive control, the I691F mutated receptor showed a slight increase of cAMP accumulation. Furthermore, I691F resulted in constitutive activation of the G(αq/11/IP signaling pathway. CONCLUSIONS/SIGNIFICANCE: Our results indicate that Ile(691 not only contributes to keeping TSHR inactive in the G(αs/cAMP pathways but also in the G(αq/11/IP cascade.

      Sexual orientation is an individual's pattern of physical and emotional arousal toward members of the same and/or opposite gender. To determine the pattern of sexual orientation and the relationship between sexual orientation and quality of life among a sample of OAU students. A descriptive cross sectional study among 481 students of OAU using a multistage sampling technique. They completed a Socio-demographic data schedule, questions on sexual orientation and the World Health Organization Quality of Life Scale - Brief version (WHO QOL-BREF). 4.9% of the sample self-identified as bisexual while 0.1% self-identified as gay/lesbian. 11.8% of the respondents reported varying degrees of attraction to the opposite gender. The mean age of sexual debut was 17.62 (±4.05). Those who self-identified as gay/lesbian/bisexual had a lower average score on all domains of the WHO QOL-BREF. Same sex sexual attraction and practice occur among young people in Nigeria and this has sexual and reproductive health implications. GLB youth report a lower QOL compared to heterosexual counterparts and this may suggest some distress among this vulnerable group. More studies should be undertaken to explore issues raised in planning interventions and health services that would improve safe sexual practices within this group.

      Full Text Available Abstract Background The intensity of the inflammation induced by Helicobacter pylori colonization is associated with the development of distal gastric cancer (GC. The host response to H. pylori has been related to genetic polymorphisms that influence both innate and adaptive immune responses. Our aim was to investigate whether the presence of the TLR4 Asp299Gly, TLR4 Thr399Ile and IL-8-251 A/T polymorphisms had any influence in the development of distal GC in a Mexican population. Methods We studied 337 patients that were divided in two groups: 78 patients with histologically confirmed distal GC and 259 non-cancer controls. The presence of H. pylori in the control population was defined by positive results of at least two of four diagnostic tests: serology, histology, rapid urease test and culture. Human DNA was purified and genotyped for TLR4 Asp299Gly polymorphism by pyrosequencing, for TLR4 Thr399Ile by PCR-RFLP and for IL8-251 by the amplification refractory mutation system (ARMS-PCR. Results The non-cancer control group was found to be in Hardy-Weinberg equilibrium at the polymorphic loci studied (chi-square H-W = 0.58 for IL8-251, 0.42 for TLR4 Asp299Gly and 0.17 for TLR4 Thr399Ile. The frequencies of mutated alleles (homozygous plus heterozygous were compared between cases and controls. We found no significant difference for TLR4- Asp299Gly [the 7.7% of distal GC patients and 7.7 % non-cancer controls (p = 0.82] and for TLR4 Thr399Ile [the 1.3% of GC patients and the 5% of the control population (p = 0.2]. In contrast, for IL-8-251 A/T, 80.77% of the GC patients and 66.4% in the control group age and gender matched had at least one copy of mutated allele (OR = 2.12, 95% CI = 1.1–4.2 (p = 0.023. Conclusion This study showed that the IL8-251*A allele could be related to the development of distal gastric cancer in this Mexican population.

      We have begun a collaborative investigation of the response of candidate first-wall inertial fusion energy (IFE) reactor chamber drywall materials to X-rays on the Z facility, and to ions on RHEPP-1, both located at Sandia National Laboratories. Dose levels are comparable to those anticipated in future direct-drive reactors. Due to the 5-10 Hz repetition rate expected in such reactors, per-pulse effects such as material removal must be negligible. The primary wall materials investigated here are graphite and tungsten in various forms. After exposure on either RHEPP or Z, materials were analyzed for roughening and/or material removal (ablation) as a function of dose. Graphite is observed to undergo significant ablation/sublimation in response to ion exposure at the 3-4 J/cm{sup 2} level, significantly below doses expected in future dry-wall power plants. Evidence of thermomechanical stresses resulting in material loss occurs for both graphite and tungsten, and is probably related to the pulsed nature of the energy delivery. These effects are not seen in typical magnetic fusion energy (MFE) conditions where these same kinds of materials are used. Results are presented for thresholds below which no roughening or ablation occurs. Use of graphite in a 'velvet' two-dimensional form may mitigate the effects seen with the flat material, and alloying tungsten with rhenium may reduce its roughening due to the increased ductility of the alloy.

      2000-01-01

      The development of a program in nuclear science and technology in Nigeria began in 1976 with the establishment of two research centers, namely, the Centre for Energy Research and Training, (CERT), Zaria and the Centre for Energy Research and Development (CERD), Ile-Ife. The choice of Neutron Activation Analysis (NAA) technique as a very effective method of training scientists in basic and applied nuclear research led to the purchase of two KAMAN A-711 Neutron Generators for the two research centers. At CERT, the neutron generator (code named ZARABUNG-1) was successfully installed and the first 14 MeV neutrons were produced through the technical assistance of the International Atomic Energy Agency (IAEA) in 1988. In 1991, a new tube-head was purchased and installed due to the expiration of the old tube. Following the completion of its permanent site, the neutron generator was re-located from the old site and re-installed at the permanent site of CERT in 1995. (author)

      The alleged use of potassium bromate (KBrO3) in bread baking led a few authors to report on the chemical methods for the determination of KBrO3 levels in bread. In order to examine the potentials of a non chemical particle induced X-ray emission (PIXE) method for this purpose, six sets of samples, each composed of flour, dough and bread from a production batch were analysed. The samples were obtained from six different bakers of bread at Ile-Ife, Nigeria. The flour samples were air-dried while others were freeze dried at about -16 °C. The samples were homogenised in an agate mortar and then pelletised. Samples were analysed at the CTN standard PIXE setup and standard procedures for thick target samples analysis were followed. In some samples significant concentrations of bromine were found. In the present work we present possible explanations for the presence of this potentially dangerous contaminant in the samples.

      Immunofixation electrophoresis (IFE) maintains its importance in diagnosing monoclonal gammopathies. In particular, urine IFE detects free light chains (FLC) in urine samples even at low concentrations and offers higher sensitivity compared to serum electrophoresis and serum IFE. The aim of the present study was to determine the place and significance of quantitative urinary protein measurement before IFE in interpreting the results of subsequent IFE and to determine the most appropriate protein concentrations for the appearance of bands. The records of a total of 600 patients, who underwent screening for Bence Jones proteinuria using IFE on 24-hour urine, were retrospectively reviewed. Urine IFE was performed using Helena SAS-I and SAS-I devices. The total protein concentration in the urine was quantitatively determined by the Pyrogallol red method, and the urine albumin level was determined using the immunoturbidimetric method. These analyses were measured on an Olympus/Beckmann AU5800. The evaluation of IFE results revealed that 311 patients had normal results, 108 patients had monoclonal bands, five patients had biclonal bands, 28 had polyclonal bands, and 148 patients had various degrees of proteinuria. ROC curves were created in order to determine the most appropriate urinary protein and albumin levels to observe bands in IFE. Accordingly, urine baseline protein level (mg/dL) showed the highest AUC value (cutoff value: 19.4 mg/dL, sensitivity: 92%, specificity: 98.2%, AUC: 0.972). The present study showed that quantitative protein measurement before IFE eliminated the disadvantages associated with the IFE method and its interpretation.

      We recently developed a practical protocol for preparing proteins bearing stereo-selectively 13 C-methyl labeled leucines and valines, instead of the commonly used 13 C-methyl labeled precursors for these amino acids, by E. coli cellular expression. Using this protocol, proteins with any combinations of isotope-labeled or unlabeled Leu and Val residues were prepared, including some that could not be prepared by the precursor methods. However, there is still room for improvement in the labeling efficiencies for Val residues, using the methods with labeled precursors or Val itself. This is due to the fact that the biosynthesis of Val could not be sufficiently suppressed, even by the addition of large amounts of Val or its precursors. In this study, we completely solved this problem by using a mutant strain derived from E. coli BL21(DE3), in which the metabolic pathways depending on two enzymes, dihydroxy acid dehydratase and β-isopropylmalate dehydrogenase, are completely aborted by deleting the ilvD and leuB genes, which respectively encode these enzymes. The ΔilvD E. coli mutant terminates the conversion from α,β-dihydroxyisovalerate to α-ketoisovalerate, and the conversion from α,β-dihydroxy-α-methylvalerate to α-keto-β-methylvalerate, which produce the preceding precursors for Val and Ile, respectively. By the further deletion of the leuB gene, the conversion from Val to Leu was also fully terminated. Taking advantage of the double-deletion mutant, ΔilvDΔleuB E. coli BL21(DE3), an efficient and residue-selective labeling method with various isotope-labeled Ile, Leu, and Val residues was established.

      Full Text Available To date, several on-treatment-level virological and serological indices that may predict the response to interferon alpha (IFN-α have been reported. However, no effective predictors, such as drug–response genes, that can be detected before administration of anti-hepatitis B virus (HBV therapy with IFN-α, have been found. In the diverse range of chronic viral infection, genes that affect human immunity play important roles in understanding host and viral co-evolution. Killer-cell immunoglobulin-like receptors (KIRs, which are highly polymorphic at the allele and haplotype levels, participate in the antiviral function of natural killer (NK cells via fine-tuning inhibition and activation of NK-cell responses that occur when the NK cells interact with human leukocyte antigen (HLA class I molecules on target cells. For each individual, the pairing of KIR and HLA ligand is genetically determined. To investigate whether a particular KIR and HLA repertoire influences the risk of HBV infection and response to IFN-α treatment for chronic hepatitis B (CHB, we genotyped the KIRs and HLA ligands of 119 hepatitis B e antigen (HBeAg-positive CHB patients. These patients included 43 patients who achieved sustained response (SR induced by IFN-α treatment for 48 weeks, 76 patients who achieved no response (NR, and 96 healthy subjects as controls. SR was defined as HBeAg loss with HBV DNA < 2,000 IU/ml and alanine aminotransferase normalization at 24 weeks posttreatment (week 72. In this study, we showed that activating KIR genes were less prevalent in Han Chinese, especially in Han Chinese with CHB, than in Caucasians. Furthermore, the KIR3DS1 gene, in combination with HLA-B Bw4-80Ile, strongly influenced the therapeutic outcomes for CHB patients who were treated with IFN-α. The frequency of the combination of genes encoding KIR3DS1 and HLA-B Bw4-80Ile was higher in patients who had a sustained treatment response than in patients who had NR [35

      Full Text Available The study appraised the economic performance of small and medium scale poultry egg production in Ife and Ilesha metropolis, Osun State Nigeria. A purposive sampling was used to select one hundred and twenty poultry egg farmers, cluster sampling was used to select areas where small and medium scale were concentrated in the study area then sixty (60 small scale and sixty (60 medium scale were randomly selected to form the population of the study. Data were collected through structured interview schedule. Descriptive statistics such as means and percentages were employed for budgetary analysis and economic performance. The ordinary least square was used to determine the significant variables influencing the gross margin of poultry egg farmers at different levels of scale of production. The study shows that the gross margin of small farms was ₦575.65 while the gross margin of medium farms was ₦43672.62. The total production cost of small and medium farms were ₦1480.25 and ₦29654.43 respectively. The results further reveal that costs of feed constituted the largest share of the total costs for the two categories of farm size. The amount spent on drug and feed were the only significant determining factors of revenue accruable to both categories of poultry egg farmers. Although, poultry egg production was profitable in the study area, the level of profit depended on the scale of operation.

      Full Text Available We discuss the quality of the two available SCIAMACHY limb ozone profile products. They were retrieved with the University of Bremen IFE's algorithm version 1.61 (hereafter IFE, and the official ESA offline algorithm (hereafter OL versions 2.4 and 2.5. The ozone profiles were compared to a suite of correlative measurements from ground-based lidar and microwave, sondes, SAGE II and SAGE III (Stratospheric Aerosol and Gas Experiment. To correct for the expected Envisat pointing errors, which have not been corrected implicitly in either of the algorithms, we applied a constant altitude shift of -1.5 km to the SCIAMACHY ozone profiles. The IFE ozone profile data between 16 and 40 km are biased low by 3-6%. The average difference profiles have a typical standard deviation of 10% between 20 and 35 km. We show that more than 20% of the SCIAMACHY official ESA offline (OL ozone profiles version 2.4 and 2.5 have unrealistic ozone values, most of these are north of 15° S. The remaining OL profiles compare well to correlative instruments above 24 km. Between 20 and 24 km, they underestimate ozone by 15±5%.

      Objectives: To review the current process for IFE at IALCH in the context of reflective testing and to examine the use of the alpha-2-globulin/alpha-1-globulin ratio as a predictor of a positive IFE result. Methods: Data for 1260 consecutive SPEP tests performed at the IALCH National Health Laboratory Service were collected between February and July 2011. SPEP and IFE were performed with a Sebia Hydrasys automated electrophoresis system. The alpha-2-globulin/alpha-1-globulin ratio was calculated using density of corresponding fractions on SPEP. Results: Analysis revealed that of the 1260 SPEPs performed during the analysis period, 304 IFEs were suggested by the reviewing pathologist. A total of 45 (15% of the suggested IFEs were subsequently requested by the attending clinicians. Almost half (46.5% (n = 20 of the suggested IFEs that were performed revealed the presence of a paraprotein. There was no statistically-significant difference between the alpha-2-globulin/alpha-1-globulin ratio for patients with positive or negative IFEs (p-value = 0.2. Conclusions: This study reveals the need for reflective addition of IFE testing by the laboratory following suspicious findings on SPEP.

    11. Genetic characterization of type 2a canine parvoviruses from Taiwan reveals the emergence of an Ile324 mutation in VP2

      2014-01-01

      Background Canine parvovirus 2 (CPV 2) is a major infectious cause of mortality in puppies. The characteristic symptom of CPV 2 disease is intestinal hemorrhage with severe bloody diarrhea. Soon after CPV was first recognized in the late 1970s, the original virus, CPV 2, was replaced in the canine population by strains carrying minor antigenic variants (termed 2a, 2b, and 2c) of the VP2 gene that could be distinguished using monoclonal antibodies and molecular analyses. Here, we provide an updated molecular characterization of the CPV 2 circulating in Taiwan. Methods In this study, 28 isolates of CPV 2 from 144 dogs with suspected CPV infection were obtained from northern, central, and southern Taiwan from 2008 to 2012 and screened by PCR. The 28 isolates were sequenced, and a phylogenetic analysis of the VP2 gene was performed. Results Of the 28 Taiwanese CPV 2 isolates, 15 were identified as new CPV 2a, and 13 were identified as new CPV 2b. Compared to the reference CPV 2a, all 15 of the CPV 2a sequences collected in this study contain an Ile324 mutation caused by a TAT to ATT mutation at nucleotides 970–972 of the VP2 gene. Conclusion Our VP2 sequence data revealed that both types are currently prevalent CPV 2 field strains circulating in Taiwan, and a unique Ile324 VP2 mutation was found in our Taiwanese CPV 2a isolates and recent Asian isolates. CPV 2c was not observed in this study. PMID:24568207

      Carbon catabolite repression (CCR) allows bacteria to selectively assimilate a preferred compound among a mixture of several potential carbon sources, thus boosting growth and economizing the cost of adaptability to variable nutrients in the environment. The RNA-binding catabolite repression control (Crc) protein acts as a global post-transcriptional regulator of CCR in Pseudomonas species. Crc triggers repression by inhibiting the expression of genes involved in transport and catabolism of non-preferred substrates, thus indirectly favoring assimilation of preferred one. We report here a nearly complete backbone and stereospecific (13)C methyl side-chain chemical shift assignments of Ile (δ1), Leu and Val of Crc (~ 31 kDa) from Pseudomonas syringae Lz4W.

      Non-nutritive sucking (NNS) is a common behavior in childhood. The association between digit sucking, dental caries and oral health has been studied with inconclusive results. The objectives of this study were to determine the prevalence of, and the association between digit sucking, caries and oral hygiene status of children age six months to 12 years, resident in Ile-Ife, Osun State, Nigeria. A cross-sectional study was conducted in Ife Central Local Government Area of Osun State. Data were collected through a household survey using a multi-stage sampling procedure from children between six months and 12 years. Details of each child's socio-demographic characteristics, digit sucking habits, caries status and oral health status were collected. The association between digit sucking, caries status and oral hygiene status was determined using Chi square and Logistic regression. The mean age of the 992 study participants was 5.8 ± (3.2) years. The prevalence of digit sucking, caries and poor oral hygiene were 7.2%, 10.5% and 2.4% respectively. The mean dmft score was 0.22 ± (0.80), mean DMFT score was 0.04 ± (0.30) while mean Oral Hygiene Index score was 1.27 ± (0.73). Digit sucking increased the odds of having caries (OR: 1.28; CI: 0.58-2.81) but decreased the odds of having poor oral hygiene (OR: 0.58; CI: 0.34-1.01) insignificantly. Digit sucking was not a significant predictor of caries and oral hygiene status, although the odds of having caries increased while the odds of having poor oral hygiene decreased with digit sucking.

      1995-01-01

      Recent decisions by DOE to proceed with the National Ignition Facility (NIF) and the first half of the Induction Systems Linac Experiments (ILSE) can provide the scientific basis for inertial fusion ignition and high-repetition heavy-ion driver physics, respectively. Both are critical to Inertial Fusion Energy (IFE). A conceptual design has been completed for a 1.8-MJ, 500-TW, 0.35-microm-solid-state laser system, the NIF. The NIF will demonstrate inertial fusion ignition and gain for national security applications, and for IFE development. It will support science applications using high-power lasers. The demonstration of inertial fusion ignition and gain, along with the parallel demonstration of the feasibility of an efficient, high-repetition-rate driver, would provide the basis for a follow-on Engineering Test Facility (ETF) identified in the National Energy Policy Act of 1992. The ETF would provide an integrated testbed for the development and demonstration of the technologies needed for IFE power plants. In addition to target physics of ignition, the NIF will contribute important data on IFE target chamber issues, including neutron damage, activation, target debris clearing, operational experience in many areas prototypical to future IFE power plants, and an opportunity to provide tests of candidate low-cost IFE targets and injection systems. An overview of the NIF design and the target area environments relevant to conducting IFE experiments are described in Section 2. In providing this basic data for IFE, the NIF will provide confidence that an ETF can be successful in the integration of drivers, target chambers, and targets for IFE

      Ozone and fine particles are current risk factors for premature death all over the globe. In coming decades, substantial improvements in public health may be achieved by reducing air pollution. The overall objective of the A-C HIA project (2011-2014) was to apply state of the art climate, air quality, and health modelling tools to assess future health impacts of O 3 and PM2.5 under different scenarios of emissions for the period 2030-2050. A-C HIA created an interdisciplinary team to study the impacts of climate change on health through air quality changes, and to establish longer-term collaborations between communities. This question has been explored at three spatial scales: global, regional (Europe), and urban (ile-de-France). We f ind that 1.5 millions of cardio-vascular deaths could be delayed each year in 2030 compared to 2010. In Europe, air-pollution-related mortality should decrease in 2030 compared to 2010. At the finer scale (ile-de-France) we found that the respiratory mortality should increase over the highly populated area of Paris. In the coming years, substantial benefits to public health could be achieved through coordinated strategies to reduce emissions of greenhouse gases and improving air quality. (authors)

      Our study describes a 1995 survey (1120 questionnaires) in the urban and rural rainforests of Ile-Ife, Osun State, Nigeria, on fuel use for cooking. We assessed the biofuel burning in Africa, in particular, and in tropical countries, in general. Included are discussions of socio-economic conditions, descriptions of the types and numbers of stoves, fuel and combustion characteristics, specific fuel consumption in both the private and commercial sectors, fuel sources and their availability, and health effects caused by cooking with firewood. We determined the weights and/or dimensions of fuel units, wood residues, fireplaces and combustion chambers. The consumptions of firewood (in kg cap{sup -1} yr{sup -1}) obtained by this method are of 515 in urban areas and 573 in rural areas. Wood usage is greater for low-income groups than for better situated householders who utilize kerosene, liquid petroleum gas (LPG), and electricity for cooking. Agricultural residues are used to start and support wood combustion; animal residues are not used as cooking fuels. (author)

      The RNAi pathway of several organisms requires presence of double stranded RNA binding proteins for functioning of Dicer in gene regulation. In C. elegans, a double stranded RNA binding protein, RDE-4 (385 aa, 44 kDa) recognizes long exogenous dsRNA and initiates the RNAi pathway. We have achieved complete backbone and stereospecific methyl sidechain Ile (δ1), Leu and Val chemical shifts of first 243 amino acids of RDE-4, namely RDE-4ΔC.

    6. Measurements and calculations for determination of discharge of 41Ar from IFEs research reactor JEEP II at Kjeller, Norway

      41 Ar is formed by neutron irradiation of 40 Ar, which occurs naturally in air with a concentration of 9300 ppm. The discharge of 41 Ar from IFEs research reactor Jeep II is yearly reported to the Norwegian Radiation Protection Authority (NRPA). Until year 2000 the reported values were based on theoretical calculations of produced 41 Ar per operating hour of 6.8 GBq/h. During 2000 and 2001 the reactor was upgraded to increase the irradiation capacity and to meet the markets demand for irradiation of 5'Si-crystalls. After the upgrading, measurements and calculations were initiated to determine the new discharge rate for 41 Ar. During reactor operation an approximately constant discharge of 41 Ar is expected, mainly due to irradiation of air in open beam channels. In addition 41 Ar is released from irradiation pockets when they are opened to transfer samples in and out during reactor stop. The new value for discharge rate was determined from measurements of air samples from the discharge channel during operation and theoretical calculations of the release from the irradiation pockets. The new discharge rate was determined to 5.9 ± 0.5 GBq/h, which is a small reduction compared to the former value of 6.8 GBq/h. A small reduction in discharge rate was expected because the number of air-filled irradiation pockets was reduced after the upgrading. In a normal year the discharge of 41 Ar will be about 2 % of the Institutes discharge permission. (orig.)

      2008-01-01

      Recent experiments at the Osaka University Institute for Laser Engineering (ILE) showed that 'Impact Fast Ignition' (IFI) could increase the neutron yield of inertial fusion targets by two orders of magnitude [1]. IFI utilizes the thermal and kinetic energy of a laser-accelerated disk to impact an imploded fusion target. ILE researchers estimate a disk velocity of 10 8 cm/sec is needed to ignite the fusion target [2]. To be able to study the IFI concept using lasers different from that at ILE, appropriate non-dimensionalization of the flow should be done. Analysis of the rocket equation gives parameters needed for producing similar IFI results with different lasers. This analysis shows that a variety of laboratory-scale commercial lasers could produce results useful to full-scale ILE experiments

      The expression levels of two DNA repair genes (CHAF1A and CHAF1B) and a chromosome segregation gene (AURKA) were susceptible to arecoline exposure, a major alkaloid of areca nut. We hypothesize that genetic variants of these genes might also be implicated in the risk of oral cancer and could be modified by substance use of betel quid or alcohol and cigarettes. A case-control study, which included 507 patients with oral cancer and 717 matched controls, was performed in order to evaluate the cancer susceptibility by the tagging single-nucleotide polymorphisms (tagSNPs) in AURKA, CHAF1A, and CHAF1B using a genotyping assay and gene-environment interaction analysis. The Phe31Ile polymorphism (rs2273535, T91A) of AURKA was significantly associated with an increased risk of oral cancer (odds ratio (OR) = 2.1, 95% confidence interval (CI) 1.2-3.5). The gene dosage of the 91A allele also showed a significant trend in risk of oral cancer (P = 0.008). Furthermore, we found the AURKA 91AA homozygote was modifiable by substance use of alcohol, betel quid, and cigarettes (ABC), leading to increased risk of oral cancer in an additive or a multiplicative model (combined effect indexes = 1.2-4.0 and 1.5-2.2, respectively). However, no association was observed between the genetic variants of CHAF1A or CHAF1B and oral cancer risk in the study. These findings reveal the functional Phe31Ile polymorphism tagSNP of AURKA may be a strong susceptibility gene in ABC-related oral cancer occurrence. The results of this betel-related oral cancer study provide the evidence of environment-gene interaction for early prediction and molecular diagnosis.

      Full Text Available The aim of this study was to evaluate the reproductive performance of Ile de France ewes undergoing dietary supplementation before and during the breeding season, with and without association with management conditions (pre-mating shearing. Thirty-six ewes with an average body weight of 66 kg were used in the experiment. Treatments involved ewes receiving or not receiving concentrate supplementation (flushing, with groups subdivided according to the management condition to which animals were subjected: shearing or lack of it. Thus, ewes were divided into four treatments: flushed and shorn; flushed and unshorn; unflushed and shorn; and unflushed and unshorn. Flushing increased weight gain and body condition score, and when associated with shearing, it promoted anticipation of estrus. Fertility rate (86.05%, calving rate (77.77%, birth rate (113.83%, and type of birth (single: 82.29% and twin: 17.71% were not influenced. Birth weight (3.96 kg and prolificacy (1.25% also were not affected. Despite the lack of changes in reproductive traits, flushing adopted during the breeding season associated with shearing anticipated estrus in ewes.

      Occurrence of lead poisoning associated with gold mining and processing was reported around March 2010 in some communities of Zamfara State, leading to hundreds of fatalities, especially among children. We have evaluated the levels of lead and other elements (both toxic and essential) in human milk and whole blood samples obtained from 27 subjects at the village of Yargalma, in Anka Local Government Area of Zamfara State. Milk and blood samples were lyophilized at the Obafemi Awolowo University Teaching Hospital Complex, lIe-Ife, and were further sterilized by gamma irradiation (20 -30 kGy) at the National Radiation Centre, Abuja. Elemental analyses were carried out at the Josef Stefan Institute, Ljubljana, Slovenia for determination of Pb, Cd, As, Se, Zn and Cu by ICP-MS; and Hg by Direct Hg analyser. The significant contamination of the environment leading to the reported cases of Pb-poisoning in Zamfara gold mines have been confirmed by elevated levels of Pb measured in samples of blood and human milk. The levels of Pb in blood ranged from 7.9 - 86.8μg/dL (mean±SD: 55.6±19.6μg/dL) while levels of this toxic element in human milk ranged from 2 - 140 ng/ml (mean±SD: 45±37 ng/ml). These values, in asymptomatic subjects, are extremely high indeed. A number of interesting correlations between elemental levels in milk and blood of mothers, and the age of mother and period after birth have also been demonstrated. For instance Mothers age significantly correlates with blood Pb (confirming accumulation in bones which affect blood lead level in lactating mothers). On the other hand, Mother's age significantly correlate negatively with Blood Selenium. Levels of the essential element Zn in both blood and milk of mother significantly correlate negatively with the time elapsed after child delivery (Baby's Age) as is reported in literature. We hesitate to suggest that breast-feeding of babies be limited in these subjects, knowing the several other important nutrients

In my essay, I show that Ile Bourbon 1730 constitutes a critique of the traditional French history which, up to recently, ignored slavery. In this perspective, formal aspects, even if they are not entirely new, are smartly used to deconstruct the official history, leading the reader to decide for him/herself how to read a BD in general, and this one in particular.

      1984-01-01

      The Japanese inertial fusion program has made important progress towards implosion fusion process and the technical development required for realizing the breakeven of inertial fusion energy. The key issues for the ICF research are the development of a high power driver, the pertinent pellet design for implosion by a super computer code, and the diagnostics of implosion process with high space and time resolution. The Institute of Laser Engineering (ILE), Osaka University, is the central laboratory for ICF research in Japan. The ILE Osaka has advanced the Kongo Project aiming at the breakeven of inertial fusion since 1980, and as the first phase, the Gekko 12 Nd glass laser of 20 kJ having 12 beams was constructed. The ILE has also the Lekko 8 CO 2 laser and the Reiden 4 light ion beam machine. In the second phase, a 100 kJ class driver will be provided. At the ILE, rare gas halide lasers such as KrF and ArF have been investigated. Laser plasma coupling, the scaling law for implosion pressure, the invention of a new type target ''Cannonball'', and the development of computer codes are described. Also the activities in universities, government laboratories and industrial companies are reported. (Kako, I.)

      Although the safety and environmental (S & E) characteristics of fusion energy have long been emphasized, these benefits are not automatically achieved. To maximize the potential S & E attractiveness of the inertial fusion energy (IFE), analyses must be performed early in the designs so that lessons can be learned and intelligent decisions made. In this work we have introduced for the first time heat transfer and thermal-hydraulics calculations as part of a state-of-the-art set of codes and libraries in order to establish an updated methodology for IFE safety analysis. We have focused our efforts primarily on two IFE power plant conceptual designs: HYLIFE-II and SOMBRERO. To some degree, these designs represent the extremes in IFE power plant designs. Also, a preliminary safety assessment has been performed for a generic target fabrication facility producing various types of targets and using various production techniques. Although this study cannot address all issues and hazards posed by an IFE power plant, it advances our understanding of radiological safety of such facilities. This will enable better comparisons between IFE designs and competing technologies from the safety point of view.

      Full Text Available Ground-based high spectral resolution Fourier-transform infrared (FTIR solar absorption spectroscopy is a powerful remote sensing technique to obtain information on the total column abundances and on the vertical distribution of various constituents in the atmosphere. This work presents results from two FTIR measurement campaigns in 2002 and 2004, held at Ile de La Réunion (21° S, 55° E. These campaigns represent the first FTIR observations carried out at a southern (subtropical site. They serve the initiation of regular, long-term FTIR monitoring at this site in the near future. To demonstrate the capabilities of the FTIR measurements at this location for tropospheric and stratospheric monitoring, a detailed report is given on the retrieval strategy, information content and corresponding full error budget evaluation for ozone (O3, methane (CH4, nitrous oxide (N2O, carbon monoxide (CO, ethane (C2H6, hydrogen chloride (HCl, hydrogen fluoride (HF and nitric acid (HNO3 total and partial column retrievals. Moreover, we have made a thorough comparison of the capabilities at sea level altitude (St.-Denis and at 2200 m a.s.l. (Maïdo. It is proved that the performances of the technique are such that the atmospheric variability can be observed, at both locations and in distinct altitude layers. Comparisons with literature and with correlative data from ozone sonde and satellite (i.e., ACE-FTS, HALOE and MOPITT measurements are given to confirm the results. Despite the short time series available at present, we have been able to detect the seasonal variation of CO in the biomass burning season, as well as the impact of particular biomass burning events in Africa and Madagascar on the atmospheric composition above Ile de La Réunion. We also show that differential measurements between St.-Denis and Maïdo provide useful information about the concentrations in the boundary layer.

      Full Text Available ABSTRACTThe objectives of this study were to analyze the food security condition, to analyze the external and internal factors that affect food security and to formulate strategies for improving food security in Tangerang Selatan. The primary data was collected by conducting a focus group discussion and questionnaire filling with purposive sampling technique. Descriptive method on secondary data such as food availability was used to analyze the food security condition. Internal Factor Evaluation (IFE matrix and External Factor Evaluation (EFE matrix were used to formulate strategies. Strengths, Weakness, Opportunities, and Threats (SWOT matrix was used to determine the alternative strategies and Quantitative Strategic Planning Matrix (QSPM was used to determine among feasible alternative strategies. The results showed that the most important internal factor is commitment of the regional leader and the most important external factor is geographical location of Tangerang Selatan.

      1983-01-01

      Nuclear power, isotope technology and basic research in physics comprises the nuclear activities of Institute for Energy Technology (IFE), Norway. These activities represented in 1983 about 60% of the gross turnover and use about 50% of the state grant. IFE's nuclear power work is now mainly connected with the Halden reactor, where international collaboration through the OECD Halden Reactor Project enables Norway to carry out advanced research in central areas of nuclear power technology. The present programme in Halden is concentrated on fuel and safety research, as well as computerbased methods for control and surveillance of reactor installations. An important part of the reactor safety work at IFE is concentrated on Nordic collaboration projects under the direction of the Nordic Coordination Committee for Atomic Energy (NKA). The isotope laboratories activity includes the provision of isotopes, irradiation technology assignements and the development of new products and application methods in the field. Activities within basic research in physics are largely based on the use of neutron beams from the JEEP II reactor for research into the structure and dynamics of solid and liquid materials. The research activity has a broad contact network with Norwegian and foreign research groups. During 1983 IFE continued its countrywide monitoring of radioactive fallout which it began in 1982 as an assignment for the Norwegian Defence Research Establishment. The Committee of IFE's Founders' report on IFE's place within Norwegian research was handled by the authorities and interested parties during 1983. This report is seen as an important foundation for IFE's further development and effort. (RF)

      Full text: Thaumatococcus danielli (Marantaceae Benn.) Benth [Miraculous berry] is a multi-purpose perennial herb that is widely distributed in the tropical rainforest areas of West Africa. The leaves are simple, broad with slender stems connected underground to the perennial rhizomes. Farmers grow it in pockets within cocoa (Theobroma cacao) and kola (Cola nitida) plantations in South western Nigeria, Ghana and Cameroon. Propagation is mainly by rhizomes cuttings and occasionally by the seed. T. danielli plays very important roles in the rural economy generating income for the peasant farmers and traders. T. danielli is used mainly in three ways by the people. The leaves are used in food wrapping because of its very good flavour and its preservative ability; and roof thatching while the stem is locally used as straw in weaving mats and in making baskets, bags, hats, hand fans and other artistic works. Research has shown that the fruits of T.danielli contain low-calorie protein named 'Thaumatin' which is about 2000 times as sweet as sucrose. The stems also can be processed to produce fibre industrially in addition to the industrial potential of Thaumatin. Thaumatin have been implicated to be suitable sweetener for diabetes patients. However, despite the great economic values, potentials and benefits of T. danielli, there is hardly any data on its elemental compositions. This work therefore presents the elemental composition of T. danielli plant's parts (Ieaves, stems, fruits (mesocarps), seeds and roots (rhizomes)) from six different towns in Osun State of Nigeria using the Particle Induced X-ray Emission (PIXE) technique.

      Full Text Available One of the characteristics of type 2 diabetes mellitus (T2DM is the state of persistent oxidative stress (OS that has been implicated in the pathogenesis of diseases such is atherosclerosis mainly through chronic hyperglycemia that stimulates production of reactive oxygen species (ROS and increases OS. Glutathione S-transferase P1 (GSTP1 is a member of the cytosolic GST superfamily. It plays an important role in neutralizing OS as an enzyme. Also, it participates in regulation of stress signaling and protects cells against apoptosis via its noncatalytic ligand-binding activity. GSTP1 Ile105Val functional polymorphism influences protein catalytic activity and stability and the aim of this study was to determine whether this gene variation influences susceptibility to atherogenesis in T2DM patients. A total of 240 individuals (140 patients with T2DM, accompanied with clinical manifestations of atherosclerosis, and 100 healthy controls were included in this study. Genomic DNA was isolated from peripheral blood cells and genotyping was performed using polymerase chain reaction followed by restriction fragment length polymorphism (PCR-RFLP analysis. We obtained no statistically significant differences in the distribution of alleles and genotypes between cases and controls (P>0.05 but association between Ile/Val (OR=0.6, 95%CI=0.35-1.05, P=0.08 and Val/Val (OR=0.45, 95%CI=0.18-1.11, P=0.08 genotypes and disease approached significance (P=0.08. Our results indicated that a larger study group is needed to establish the true relationship between potentialiy protective allele Val and the disease, and to determine the influence of other GSTP1 polymorphisms on atherogenesis in T2DM patients.

      Institute for Energy Technology has made a projection of energy use in stationary sector of Norway up to 2050 and by the use of the Norwegian MARKAL model analyzed various scenarios. Total increase demand in stationary sectors by 6 TWh, or 4% to 2020 and by 29 TWh or 16% for 2050, which increase primarily comes in the buildings. Scenarios are analyzed to show the long-term potential given the various operating parameters. An important scenario that is analyzed, the fulfillment of renewable directive. In 2005, the renewable share in Norway about 61%. In the analysis it is assumed that the renewable share to be 75% as of 2020. Implementation of energy efficiency will have a crucial role to increase the renewable share, and efficiency contributes with 26 TWh in the base scenario. What percentage of energy efficiency measures are really implemented will have a great impact on how much renewable electricity to be produced, or how much more bio-energy that must be used, in order to achieve the goal of renewable directive.

      Carvajal syndrome is an autosomal dominant or autosomal recessive disorder, manifesting with dilated cardiomyopathy, woolly hair, and palmoplantar keratoma. Additional manifestations can be occasionally found. Carvajal syndrome may be due to mutations in the desmocollin-2, desmoplakin, or plakophilin-2 gene. We report a family with Carvajal syndrome which additionally presented with hypoacusis, noncompaction, recurrent pharyngeal infections, oligodontia, and recurrent diarrhoea. Father and brother were also affected and had died suddenly, the father despite implantation of a cardioverter defibrillator (ICD). Genetic studies revealed the novel pathogenic mutation c.1678A > T in the desmoplakin gene resulting in the amino acid change Ile to Phe at position 560 in the index case and her brother. The index case underwent ICD implantation recently. Phenotypic manifestations of Carvajal syndrome are even broader than so far anticipated, the number of mutations in the desmoplakin gene responsible for Carvajal syndrome is still increasing, and these patients require implantation of an ICD as soon as their diagnosis is established.

      2016-03-01

      In 2014 the Preparatory Commission for the Comprehensive Nuclear-Test-Ban Treaty Organization (CTBTO) undertook an Integrated Field Exercise (IFE14) in Jordan. The exercise consisted of a simulated 0.5-2 kT underground nuclear explosion triggering an On-site Inspection (OSI) to search for evidence of a Treaty violation. This research paper evaluates two of the OSI techniques used during the IFE14, laboratory-based gamma-spectrometry of soil samples and in-situ gamma-spectrometry, both of which were implemented to search for 17 OSI relevant particulate radionuclides indicative of nuclear explosions. The detection sensitivity is evaluated using real IFE and model data. It indicates that higher sensitivity laboratory measurements are the optimum technique during the IFE and within the Treaty/Protocol-specified OSI timeframes. Copyright © 2016 Elsevier Ltd.

      2012-09-15

      In 1917, Albert Einstein suggested the theory of stimulated emission of light that led to the development of the laser. The first laser, based on Einstein's theory, was demonstrated by the Maiman experiment in 1960. In association with the invention and developments of the laser, N.G. Basov, A. Prokorov and C.H. Towns received the Nobel prize for physics in 1963. On the other hand, it had been recognized that nuclear fusion energy is the energy source of our universe. It is the origin of the energy in our sun and in the stars. Right after the laser oscillation experiment, it was suggested by J. Nuckolls, E. Teller and S. Colgate in the USA and A. Sakharov in the USSR that nuclear fusion induced by lasers be used to solve the energy problem. Following the suggestion, the pioneering works for heating plasmas to a thermonuclear temperature with a laser were published by N. Basov, O.N. Krohin, J.M. Dawson, C.R. Kastler, H. Hora, F. Flux and S. Eliezer. The new concept of fusion ignition and burn by laser 'implosion' was proposed by J. Nuckolls, which extended the spherically imploding shock concept discovered by G. Guderley to the laser fusion concept. Since then, laser fusion research has started all over the world. For example, many inertial fusion energy (IFE) facilities have been constructed for investigating implosion physics: Lasers: GEKKO I, GEKKO II, GEKKO IV, GEKKO MII and GEKKO xII at ILE, Osaka University, Japan; JANUS, CYCLOPS, ARUGUS, SHIVA and NOVA at Lawrence Livermore National Laboratory (LLNL), USA; OMEGA at the Laboratory for Laser Energetics (LLE), University of Rochester, USA; PHEBUS at Limeil, Paris, France; the ASTERIx iodine laser at the Max-Planck-Institut fuer Plasmaphysik (IPP), Garching, Germany; MPI, GLECO at the Laboratoire d'Utilisation des Lasers Intenses (LULI), ecole Polytecnique, France; HELIOS at Los Alamos National Laboratory, USA; Shengan II at the Shanghai Institute of Optics and Fine Mechanics, China; VULCAN at the Rutherford

      Full Text Available The objective of this work was to investigate the prof ile of orange consumption and consumer attitude to minimally processed orange. Seven hundred and seventeen questionnaires were applied in commercial establishments in three municipalities in the State of São Paulo, Brazil. Main results of this research are: orange is a highly appreciated fruit, being consumed in natura and also as its natural juice, moreover orange is purchased weekly at hypermarkets, the purchase intent for minimally processed orange was low and the likely consumers’ willingness of paying for that product would be near 200% over the ‘in natura’ fruit. Considering the high consume of ‘in natura’ orange and the increasing need for convenience and practicality, it is possible to affirm that there is a potential for commercializing minimally processed orange.

      Full Text Available Increasingly blended learning, as a combination of face-to-face and online instruction is applied in university classrooms. In this study the use of an interactive learning environment (ILE, within a Sakai-based learning management system, as well as face-to-face teaching and learning in a first-year Afrikaans language class is explored. The Technology Acceptance Model (TAM was employed by means of a survey and the Structure Equation Model was used to explore factors relevant to this first-year class. In addition, qualitative research was conducted through an open questionnaire in order to determine the perceptions regarding the blended learning context and the ILE. It was found that students are generally able to function within the ILE and they are quite positive towards the use of the learning environment for learning and teaching. However, it is clear that some students still prefer printed study material. Despite the fact that students indicated that they use the ILE daily, actual usage statistics did not always correspond. Finally, this paper makes suggestions with regard to adapting teaching in terms of students’ behaviour based on their computer anxiety and Internet self-efficacy as well as the perceived usefulness and ease of use of the ILE.

The constants of propagation and attenuation of the surface plasmon-polariton modes are calculated. The effective magnetic field induced by surface plasmon modes in the dielectric due to the IFE is estimated to reach above 1 tesla. The possibility to control the distribution of the magnetic field by chemical potential of graphene is shown. The concept of strain-driven control of the IFE in the structure has been proposed and investigated.

      Directly observed treatment short-course (DOTS) strategy is an effective mode of treating TB. We aimed to study the cost effectiveness and patients' satisfaction with home based direct observation of treatment (DOT), an innovative approach to community-based DOT (CBDOT) and hospital based DOT (HBDOT). A randomized controlled trial involving 150 newly diagnosed pulmonary TB patients in four TB clinics in Ile Ife , Nigeria, was done. They were randomly assigned to receive treatment with anti TB drugs for the intensive phase administered at home by a TB worker (CBDOT) or at the hospital (HBDOT). Outcome measures were treatment completion/default rates, cost effectiveness and patients' satisfaction with care using a 13 item patients satisfaction questionnaire (PS-13) at 2 months. This trial was registered with pactr.org: number PACTR 201503001058381. At the end of intensive phase, 15/75 (20%) and 2/75 (3%) of patients in the HBDOT and CBDOT, respectively had defaulted from treatment, p= 0.01. Of those with pretreatment positive sputum smear, 97% (68/70) on CBDOT and 54/67 (81%) on HBDOT were sputum negative for AFB at the end of 2 months of treatment, p=0.01. The CBDOT method was associated with a higher patient satisfaction score compared with HBDOT (OR 3.1; 95% CI 1.25-7.70), p=0.001.The total cost for patients was higher in HBDOT (US$159.38) compared with the CBDOT (US$89.52). The incremental cost effectiveness ratio was US$410 per patient who completed the intensive phase treatment with CBDOT. CBDOT is a cost effective approach associated with better compliance to treatment and better patient satisfaction compared to HBDOT. © The Author 2015.

      Intense ion beams may be the best option for an Inertial Fusion Energy (IFE) driver. While light ions may be the long-term pulsed power approach to IFE, the current economic climate is such that there is no urgency in developing fusion energy sources. Research on light ion beams at Sandia will be suspended at the end of this fiscal year in favor of z-pinches studying ICF target physics, high yield fusion, and stewardship issues. The authors document the status of light ion research and the understanding of the feasibility of scaling light ions to IFE

      The goal of z-pinch inertial fusion energy (IFE) is to extend the single-shot z-pinch inertial confinement fusion (ICF) results on Z to a repetitive-shot z-pinch power plant concept for the economical production of electricity. Z produces up to 1.8 MJ of x-rays at powers as high as 230 TW. Recent target experiments on Z have demonstrated capsule implosion convergence ratios of 14-21 with a double-pinch driven target, and DD neutron yields up to 8x10exp10 with a dynamic hohlraum target. For z-pinch IFE, a power plant concept is discussed that uses high-yield IFE targets (3 GJ) with a low rep-rate per chamber (0.1 Hz). The concept includes a repetitive driver at 0.1 Hz, a Recyclable Transmission Line (RTL) to connect the driver to the target, high-yield targets, and a thick-liquid wall chamber. Recent funding by a U.S. Congressional initiative for $4M for FY04 is supporting research on RTLs, repetitive pulsed power drivers, shock mitigation, full RTL cycle planned experiments, high-yield IFE targets, and z-pinch power plant technologies. Recent results of research in all of these areas are discussed, and a Road Map for Z-Pinch IFE is presented. (author)

      A central feature of an Inertial Fusion Energy (IFE) power plant is a target that has been compressed and heated to fusion conditions by the energy input of the driver. The IFE target fabrication programs are focusing on methods that will scale to mass production, and working closely with target designers to make material selections that will satisfy a wide range of required and desirable characteristics. Targets produced for current inertial confinement fusion experiments are estimated to cost about $2500 each. Design studies of cost-effective power production from laser and heavy-ion driven IFE have found a cost requirement of about $0.25-0.30 each. While four orders of magnitude cost reduction may seem at first to be nearly impossible, there are many factors that suggest this is achievable. This paper summarizes the paradigm shifts in target fabrication methodologies that will be needed to economically supply targets and presents the results of ''nth-of-a-kind'' plant layouts and concepts for IFE power plant fueling. Our engineering studies estimate the cost of the target supply in a fusion economy, and show that costs are within the range of commercial feasibility for laser-driven and for heavy ion driven IFE

      Kaposi's Sarcoma (KS) is a tumour of multicentric origin with increased frequency after organ transplantation. To date, only North American data from the Cincinnati Transplant Tumor Registry have given some information about this disease in organ transplant recipients, but its true prevalence still has to be determined. In order to analyze Kaposi's sarcoma after kidney, liver and heart transplantation, we performed a retrospective study using the oldest registry of organ transplant recipients in Europe. Among all 7923 organ transplant recipients recorded in the Groupe Collaboratif de Recherche en Transplantation de l'Ile de France (GCIF) registry from 1968 to 1990, we analyzed the prevalence and the clinical characteristics of Kaposi's sarcoma in 6229 kidney, 727 liver and 967 heart transplant recipients. In the subgroup of kidney transplant recipients, we assessed the role of cyclosporine on disease evolution. Overall prevalence of Kaposi's sarcoma after organ transplantation was 0.52%, but it was significantly higher among liver (1.24%) than among kidney (0.45%) and heart (0.41%) transplant recipients. Chronic hepatitis B surface antigen carriers were more frequent in liver than in kidney transplant recipients who developed Kaposi's sarcoma (66% vs 21%, p < 0.03). Following kidney transplantation, Kaposi's sarcoma was more severe in patients receiving cyclosporine (n = 16) when compared with those under conventional immunosuppression (n = 12). True prevalence of Kaposi's sarcoma among European transplant recipients is high (0.52%) and appeared significantly higher in liver compared with other organ transplant recipients. Cyclosporine seems to increase severity of the disease among kidney transplant recipient.

      A field study on the runoff of pesticides was conducted during the cultivation period in 2004 on a hydraulically isolated rice farm of 120 ha surface with one central water outlet. Four pesticides were studied: Alphamethrin, MCPA, Oxadiazon, and Pretilachlor. Alphamethrin concentrations in runoff never exceeded 0.001 μg L -1 . The three other pesticides were found in concentrations between 5.2 and 28.2 μg L -1 in the runoff water shortly after the application and decreased thereafter. The data for MCPA compared reasonably well with predictions by an analytical runoff model, accounting for volatilization, degradation, leaching to groundwater, and sorption to soil. The runoff model estimated that runoff accounted for as much as 18-42% of mass loss for MCPA. Less runoff is observed and predicted for Oxadiazon and Pretilachlor. It was concluded that runoff from rice paddies carries important loads of dissolved pesticides to the wetlands in the Ile de Camargue, and that the model can be used to predict this runoff. - Runoff of dissolved pesticides was measured on a rice farm in the Camargue (France) and modeled with an analytical model

      Development of a new technology for commercial application can be significantly accelerated by leveraging related technologies used in other markets. Synergies across multiple application domains attract research and development (R and D) talent - widening the innovation pipeline - and increases the market demand in common components and subsystems to provide performance improvements and cost reductions. For these reasons, driver development plans for inertial fusion energy (IFE) should consider the non-fusion technology base that can be lveraged for application to IFE. At this time, two laser driver technologies are being proposed for IFE: solid-state lasers (SSLs) and KrF gas (excimer) lasers. This document provides a brief survey of organizations actively engaged in these technologies. This is intended to facilitate comparison of the opportunities for leveraging the larger technical community for IFE laser driver development. They have included tables that summarize the commercial organizations selling solid-state and KrF lasers, and a brief summary of organizations actively engaged in R and D on these technologies.

      Full Text Available The dynamics and interactions between stem cell pools in the hair follicle (HF, sebaceous gland (SG, and interfollicular epidermis (IFE of murine skin are still poorly understood. In this study, we used multicolor lineage tracing to mark Lgr6-expressing basal cells in the HF isthmus, SG, and IFE. We show that these Lgr6+ cells constitute long-term self-renewing populations within each compartment in adult skin. Quantitative analysis of clonal dynamics revealed that the Lgr6+ progenitor cells compete neutrally in the IFE, isthmus, and SG, indicating population asymmetry as the underlying mode of tissue renewal. Transcriptional profiling of Lgr6+ and Lgr6− cells did not reveal a distinct Lgr6-associated gene expression signature, raising the question of whether Lgr6 expression requires extrinsic niche signals. Our results elucidate the interrelation and behavior of Lgr6+ populations in the IFE, HF, and SG and suggest population asymmetry as a common mechanism for homeostasis in several epithelial skin compartments.

      Waardenburg syndrome (WS) is characterized by an association of pigmentation abnormalities and sensorineural hearing loss. Four types, defined on clinical grounds, have been delineated, but this phenotypic classification correlates imperfectly with known molecular anomalies. SOX10 mutations have been found in patients with type II and type IV WS (i.e., with Hirschsprung disease), more complex syndromes, and partial forms of the disease. The phenotype induced by SOX10 mutations is highly variable and, except for the neurological forms of the disease, no genotype-phenotype correlation has been characterized to date. There is no mutation hotspot in SOX10 and most cases are sporadic, making it particularly difficult to correlate the phenotypic and genetic variability. This study reports on three independent families with SOX10 mutations predicted to result in the same missense mutation at the protein level (p.Met112Ile), offering a rare opportunity to improve our understanding of the mechanisms underlying phenotypic variability. The pigmentation defects of these patients are very similar, and the neurological symptoms showed a somewhat similar evolution over time, indicating a potential partial genotype-phenotype correlation. However, variability in gastrointestinal symptoms suggests that other genetic factors contribute to the expression of these phenotypes. No correlation between the rs2435357 polymorphism of RET and the expression of Hirschsprung disease was found. In addition, one of the patients has esophageal achalasia, which has rarely been described in WS. © 2014 Wiley Periodicals, Inc.
