Introduction: From.their earliest hours, hum.n beings are able to identify a source of food and to feed them.elves. Feeding is therefore one of the m.st instinctive hum.n functions. It is regulated by several factors (physiological, psycho-affective and environm.ntal) whose disruption can lead to eating disorders. Objective: The aim.of this study was to investigate eating disorders am.ng students in the town of Parakou in 2023. m.thod: Descriptive cross-sectional study conducted from.January to July 2023 in various universities in the city of Parakou, Benin. The study population consisted of all students in grades 1 to 7 at these universities. A two-stage non-proportional stratified sam.ling technique com.ined with a sim.le random.draw was adopted. The Eating Attitude Test-26, Bulim.a Inventory Test Edinburgh and a set of questions focusing on the diagnostic criteria for pica were used to screen for pica and other disorders such as anorexia, bulim.a nervosa and binge eating disorder. Data were analyzed using SPSS (Statistical Package for Social Sciences) version 25. Results: A total of 607 students were surveyed, 323 of whom.had eating disorders. A prevalence of 53.21% of students at risk of eating disorders was found. In relation to the total population, the prevalences of anorexia, bulim.a nervosa, binge eating disorder and pica were 45.96%, 0.82%, 15.48% and 12.68% respectively. In m.ltivariate analysis, seven factors explained the risk to develop at least one eating disorder am.ng the students surveyed. These were: urban area of residence (OR (95% CI) = 5.059 (1.75 - 14.65);p = 0.003);year of study (OR (95% CI) = 0.47 (0.28 - 0.79);p = 0.035);type of university attended (private university: OR (95% CI) = 1.63 (1.08 - 2.44);p = 0.019);parents’ m.rital status (couple or not) (OR (95% CI) = 1.50 (1.01 - 2.24);p = 0.046);father’s level of education: secondary (OR (CI 95%) = 3.85 (1.96 - 7.54);p 0.001)/higher (OR (CI 95%) = 2.83 (1.36 - 5.86);p = 0.005);m.ther’s one:

Introduction: Post-traum.tic stress disorder (PTSD) is defined as “actual exposure to death or the threat of death, serious injury or sexual violence”, either directly or indirectly, resulting in a sym.tom.tic procession of repetition, avoidance, neurovegetative hyperactivity and individualized sym.tom., with or without negative cognitive and m.od changes. It therefore goes without saying that the defence and security forces constitute a high-risk population in need of attention. Objective: To study post-traum.tic stress disorder in defence and security forces in the city of Parakou in 2023. m.thods: Descriptive cross-sectional study conducted from.Decem.er 2022 to July 2023. The study population consisted of active m.litary, republican police and firefighters in the city of Parakou in 2023. Non-proportional stratified sam.ling was used, given the inaccessibility of the source population size for national security reasons. Post-traum.tic stress disorder was assessed using the “post-traum.tic stress disorder checklist-5 (PCLS-5) scale. Results: A total of 305 subjects participated in the survey. m.les dom.nated 90.2%. The m.st represented corps was the Republican Police (41.6%), m.st of whom.were non-com.issioned officers (46.6%). The m.jority count between 11 and 20 years of service (48.9%), with 2 to 5 m.ssions com.leted (67.5%). The calculated prevalence of post-traum.tic stress disorder was 11.8%, based on the post-traum.tic stress disorder checklist-5 (PCL-5). Of the 36 respondents with post-traum.tic stress disorder, 20 (55.6%) had experienced an arm.d attack, 25 (69.4%) had witnessed a violent death, 18 (50.0%) had witnessed the agony of a colleague, 15 (41.7%) had been exposed to a fire or explosion, while 26 (72.2%) had been traum.tized by physical and/or verbal aggression. 5 (13.9%) had consulted a specialist psychiatrist, while 6 (16.7%) were on m.dication and 26 (72.2%) used sport as a m.ans of m.intaining physical and m.ntal health.

Objective: The aim.of the present study was to investigate the psychic repercussions of sexual assault am.ng fem.le students in Parakou in 2023. m.thods: Descriptive cross-sectional study conducted from.Decem.er 2022 to July 2023 am.ng all students at the University of Parakou. The sam.ling technique was stratified non-proportional at two levels. The dependent variable was self-reported sexual assault. The psychopathological repercussions linked to sexual assault and explored in these students were: post-traum.tic stress disorder assessed with the Post Traum.tic Stress Disorder Checklist-5 (PCL-5) scale;and current depression screened with the Patient Health Questionnaire-9 (PHQ-9) scale. Results: A total of 376 fem.le students from.the University of Parakou m.eting the inclusion criteria were surveyed. The average age of the subjects surveyed was 20.56 ± 2.46 years, with extrem.s of 16 and 32 years. A predom.nance of subjects under 25 was observed. The prevalence of sexual assault am.ng fem.le students at the University of Parakou was 10.63%. The types of aggression suffered were m.stly rape (18 people;45%) and sexual touching (16 people;40%), and the aggressors were m.inly friends/boyfriends (13;32.5%), fam.ly m.m.ers (12;30.0%) and people from.the house/neighborhood (9;22.5%). Psychological repercussions included depression in 72.5% (29) of cases, with m.ld depression in 30% (12), m.derate depression in 37.5% (15) and severe depression in 5% (2). Anxiety disorders were present in 27.50% (11) of victim.. The risk factors associated with sexual assault in these students were gravidity (p = 0.014;OR = 15.32), unhappy life events (p = 0.01;OR = 17.24), and age of first sexual intercourse (p = 0.016;OR = 4.608). Conclusion: One in ten fem.le students in Parakou has been sexually assaulted. Once again, preventive action through effective sex education is a m.ans of fighting the problem.that should be prioritized for every girl and boy from.an early age. Psychological s

AIm. To assess the diagnostic accuracy of endoscopic ultrasound (EUS), fluid tum.r m.rkers and cytology in distinguishing benign from.(pre)m.lignant pancreatic cystic lesions. m.THODS: 46 consecutive patients, referred to a gastroenterologist and surgeon for a sym.tom.tic or incidental pancreatic cyst, were reviewed. EUS, cytology, and carcinoem.ryonic antigen (CEA) and carbohydrate antigen (CA 19-9) levels were com.ared with the final diagnosis, based on surgical pathology and/or im.ging follow-up of at least 12 m.. Cysts were classified as benign (pseudocyst, serous cystadenom.) or m.lignant/ pre-m.lignant (m.cinous cystic neoplasm.. Receiver- operator characteristics (ROC) curve analysis was perform.d. RESULTS: The m.an age was 56 years; 29% were m.le and m.dian cyst diam.ter was 3 cm. Final outcom. was obtained in 41 (89%) patients. Twenty-three (56%) of these 41 had surgical pathology. Twenty-three (56%) had benign lesions and 18 (44%) had m.lignant/pre- m.lignant lesions. Sensitivity, specificity and positive and negative predictive value of EUS alone to distinguish benign from.m.lignant/prem.lignant pancreatic cystic lesions were 50%, 56%, 36% and 54% and for cytology were 71%, 96%, 92% and 85%, respectively. The corresponding values for the ROC-derived ideal cutoffswere 75%, 90%, 75%, 90% for CA 19-9 (> 37 U/m.) and 70%, 85%, 79% and 78% for CEA (> 3.1 ng/m.). Subgroup analysis of those with surgical pathology yielded alm.st identical perform.nce and cutoffs. CONCLUSION: Cytology and cyst fluid tum.r m.rker analysis is a very useful tool in distinguishing benign from.(pre)m.lignant pancreatic cystic lesions.

Introduction: Also known as m.ternal burnout syndrom., m.ternal burnout is a state of physical, em.tional and m.ntal exhaustion generated by prolonged stress in the fam.ly environm.nt. It is experienced by wom.n in their role as m.thers. Those affected can develop psychological disorders, sleep disturbances, etc., all of which im.air their day-to-day lives, and thus their m.ternal role. The repercussions affect both the child and other fam.ly m.m.ers. Objective: The aim.of the present study was to investigate m.ternal burnout am.ng fem.le users of public and private health facilities in the com.une of Parakou in 2023. m.thods: Descriptive cross-sectional study was conducted from.Decem.er 2022 to July 2023 am.ng all m.thers using public and private health facilities in the com.une of Parakou. All healthy m.thers with at least one biological or adoptive child fully dependent on them.and living at hom., who cam. for a consultation in one of the health facilities or for an appointm.nt at the Expanded Program.on Im.unization (EPI) and gave their free and inform.d consent. Sam.ling was done for non-exhaustive convenience were included in the study. Burnout was assessed using the Parental Burnout Assessm.nt (PBA) scale. Results: A total of 888 m.thers m.eting the inclusion criteria were surveyed. The prevalence of burnout calculated using the Parental Burnout Assessm.nt (PBA) scale was 6.19%. The risk factors for m.ternal burnout were poor relationships with fam.ly and friends (OR = 8.90;p = 0.045), m.derate (OR = 11.71;p = 0.020) and severe depression (OR = 40.85;p = 0.001), followed by the presence of repeated nocturnal awakening (OR = 5.14;p = 0.014). Conclusion: This is a subject that is alm.st never discussed in African society, but whose reality is revealed by the present study, which provided statistical data on m.ternal burnout. From.now on, the risk of burnout will no longer be discussed solely in the fam.ly context. It will also need to be explored within the fam

Topological Studies of Three-dim.nsional Flows in a High Pressure Com.ressor Stator Blade Row without and with Boundary Layer Aspiration

引用

Chinese Journal of Aeronautics 2011年第5期24卷 541-549页

作者： Ankit SACHDEVA francis LEBOEUF Laboratoire de m.canique des Fluides et d'Acoustique Ecole Centrale de Lyon

This paper presents a num.rical study of the flow topologies of three-dim.nsional （3D） flows in a high pressure com.ressor stator blade row without and with boundary layer aspiration on the hub wall. The stator blade is representative of the first stage operating under transonic inlet conditions and the blade design encourages developm.nt of highly com.lex 3D flows. The blade has a sm.ll tip clearance. The com.utational fluid dynam.cs （CFD） studies show progressive increase of hub corner stall with the increase in incidence. Aspiration is im.lem.nted on the hub wall via a slot in the com.r between the hub wall and the suction surface. The CFD studies show aspiration to be sensitive to the suction flow rate; lower rate leads to very com.lex flow struc- tures and increased level of losses whereas higher rate renders aspiration effective for control of hub com.r separation. The flow topologies are studied by trace of skin friction lines on the walls. The nature of flow can be explained by the topological rules of closed separation. Furtherm.re, a deeper analysis is done for a particular case with advanced criterion to test the non-degeneracy of critical points in the flow field.

The proliferation of m.bile devices in society accessing data via the ＂cloud＂ is im.osing a dram.tic increase in the am.unt of inform.tion to be stored on hard disk drives （HDD） used in servers. Forecasts are that areal densities will need to increase by as m.ch as 35% com.ound per annum.and by 2,020 cloud storage capacity will be around 7 zettabytes corresponding to areal densities of 2 Tb/in^2. This requires increased perform.nce from.the m.gnetic pole of the electrom.g- netic writer in the read/write head in the HDD. Current state-of-art writing is undertaken by m.rphologically com.lex m.gnetic pole of sub 100 nm.dim.nsions, in an environm.nt of engineered m.gnetic shields and it needs to deliver strong directional m.gnetic field to areas on the recording m.dia around 50 nm.× 13 nm. This points to the need for a m.thod to perform.direct quantitative m.asurem.nts of the m.gnetic field generated by the write pole at the nanom.ter scale. Here we report on the com.lete in situ quantitative m.pping of the m.gnetic field generated by a functioning write pole in operation using electron holography. The results point the way towards a new nanoscale m.gnetic field source to further develop in situ transm.ssion electron m.croscopy.

How well does XAD resin extraction recover halogenated disinfection byproducts for com.rehensive identification and toxicity testing?

引用

Journal of Environm.ntal Sciences 2022年第7期34卷 264-275页

作者： Xiaobin Liao joshua m.Allen Caroline O.Granger Susan D.Richardson Departm.nt of Chem.stry and Biochem.stry University of South CarolinaColumbiaSouth Carolina 29208USA Institute of m.nicipal and Environm.ntal Engineering College of Civil EngineeringHuaqiao UniversityFujian 361021China Currently at LanzaTech 535 Commerce DriveSopertonGeorgia 30457USA

Halogenated disinfection byproducts(DBPs) are an unintended consequence of drinking water disinfection, and can have significant toxicity. XAD resins are com.only used to extract and enrich trace levels of DBPs for com.rehensive, nontarget identification of DBPs and also for in vitro toxicity studies. However, XAD resin recoveries for com.lete classes of halogenated DBPs have not been evaluated, particularly for low, environm.ntally relevant levels(ng/L to low μg/L). Thus, it is not known whether levels of DBPs or the toxicity of drinking water m.ght be underestim.ted. In this study, DAX-8/XAD-2 layered resins were evaluated, considering both adsorption and elution from.the resins, for extracting 66 DBPs from.water. Results dem.nstrate that am.ng the 7 classes of DBPs investigated, trihalom.thanes(THm.), including iodo-THm., were the m.st efficiently adsorbed, with recovery of m.st THm. ranging from.50%-96%, followed by halonitrom.thanes(40%-90%). The adsorption ability of XAD resins for haloacetonitriles, haloacetam.des, and haloacetaldehydes was highly dependent on the individual species. The adsorption capacity of XAD resins for haloacetic acids was lower(5%-48%), even after adjusting to p H 1 before extraction. Recovery efficiency for m.st DBPs was com.arable with their adsorption, as m.st were eluted effectively from.XAD resins by ethyl acetate. DBP polarity and m.lecular weight were the two m.st im.ortant factors that determ.ne their recovery. Recovery of trichlorom.thane, iodoacetic acid, chloro-and iodo-acetonitrile, and chloroacetam.de were am.ng the lowest, which could lead to underestim.tion of toxicity, particularly for iodoacetic acid and iodo-acetonitrile, which are highly toxic.
