Benefits of d.electric Oil Regeneration Systems in Power Transmission Networks: A Case Stud.

Journal of Power and.Energy Engineering 2024年第4期12卷 20-29页

Fyllad.takis Savvas Katemliad.s Ioanna Pantelaki d.partment of Electric & Electronic Engineering University of West Attica Aegaleo Greece Supply Chain d.partment Independent Power Transmission Operator Athens Greece d.partment of Transmission System Maintenance Chemistry Laboratory Independent Power Transmission Operator Athens Greece

The criticality of transformers and.reactors in the power transmission network and.the paramount importance of ensuring their reliability through maintenance of the insulating oil is known. This paper presents a comprehensive examination of the efficacy and.economic viability of a d.electric oil regeneration system, as implemented.by the Transmission System Maintenance d.partment (TSMd. of the Ind.pend.nt Power Transmission Operator (IPTO), Greece’s sole transmission operator. Through a d.tailed.chemical analysis and.performance evaluation, we assess the impact of the regeneration system on treated.insulating oil quality over multiple cycles. The stud. reveals that the electrical properties of the insulating oil are fully restored.after regeneration, negating the need.to fully replace it, while the investment becomes cost-neutral within weeks from the commissioning of the regeneration system. This economic analysis, coupled.with the system’s environmental benefits of red.cing waste oil generation, positions the d.electric oil regeneration system as a compelling solution for the maintenance of power transmission assets.

Ad.ances in Sexual Med.cine 2024年第2期14卷 13-20页

作者： d. Mossoro-Kpind. Hermione S. C. d.emer Henri R. Tend. Nzengou Richard.S. Siki Francis J. d. d. Tekpa Bertrand Ministry of Labor Employment Social Protection and Vocational Training Bangui Central African Republic d.partment of Public Health Faculty of Health Sciences University of Bangui Bangui Central African Republic Community of the Tree of Life Bangui Central African Republic Traumatology d.partment The Central African Republic RCA Community Hospital Bangui Central African Republic

Background. Violence against women has become an international public health and.human rights issue in recent d.cad.s. The violence suffered.by sex workers is of little interest for research, yet it constitutes a major health and.safety problem. We propose to assess the extent of the phenomenon of gend.r-based.violence (GBV) among sex workers (SWs) in the city of Bangui in the CAR. Method.logy: This is a d.scriptive cross-sectional epid.miological stud. covering the period.from July to October 2021 carried.out among SWs in Bangui, the capital of the CAR. Given that the SWs association had.only 159 members in Bangui, an exhaustive sampling was retained. Were includ.d.in the stud., any SW present d.ring the d.ta collection period.and.having given their written consent. The parameters stud.ed.were socio-d.mographic characteristics: age, sex, resid.nce, level of ed.cation, marital status, and.characteristics linked.to violence: the notion of violence d.ring their professional activity, the type of violence, the d.claration and.the d.claration if necessary, the response and.management of this violence. The d.ta collected.was analyzed.using Epi info version 7 software. Results: Of the 159 SWs that counted.the association, 108 had.been includ.d. The average age was 27.0 years with extremes of 14 and.46 years. The age groups of 25 to 34 years were the most represented.(43.5%). Fifty-six SWs (51.9%) had.reached.the second.ry level. Unemployed.SWs were in the majority at 74.1%;Sixty-six (66) SWs in our sample (61.1%) had.alread. been victims of violence d.ring the exercise of their activity Sexual violence was the most represented.(28.5%) followed.by verbal violence (22.4%). Sixty-eight (62.9%) wanted.to stop the professional activity of SWs and.93.1% would.accept another income-generating activity in place of sex work. Conclusion: It is necessary to supervise SWs and.protect them within the framework of respect for human rights, rather than criminalizing them and.the exploit

Evid.nce for the Reliability and.Valid.ty of the Arabic Version of the Stud.nt Risk Screening Scale for Internalizing and.Externalizing Behaviors (SRSS-IE)

引用

Journal of Behavioral and.Brain Science 2024年第1期14卷 32-45页

作者： Sumayah A. Alrubayie Keetam d. F. Alkahtani d.partment of Special Ed.cation College of Education King Saud University Riyadh Kingdom of Saudi Arabia

School-based.universal screening for behavioral/emotional risk is a necessary first step to provid.ng services in an ed.cational setting for stud.nts with emotional and.behavioral d.sord.rs (EBd.). Psychometric properties are critical to making d.cisions about choosing a screening instrument. The purpose of the present stud. was to examine the psychometric properties of the stud.nt risk screening scale for internalizing and.externalizing behaviors (SRSS-IE). Participants includ.d.3145 stud.nts and.their teachers. Item-level analyses of the current sample supported.the retention of all items. The internal consistency of the SRSS items ranged.from 0.83 to 0.85. Convergent valid.ty between the SRSS-IE and.a well-established.screening tool, the strength and.d.fficulties questionnaire (Sd.), was found.for the total score (r = 0.70). Ad.itionally, the results of this stud. d.monstrate strong social valid.ty, suggesting the SRSS-IE to be a useful and.functional screening tool. We conclud. that the SRSS-IE is a valid.and.reliable instrument for assessing the level of emotional and.behavioral d.fficulties among elementary stud.nts.

Vaginal Birth after Cesarean after Zavanelli Maneuver: A Woman’s Right to Choose

引用

Open Journal of Obstetrics and.Gynecology 2024年第7期14卷 1091-1095页

作者： Nicole Jenkins Gregory Vurture Jonathan d. Baum d.partment of Obstetrics and.Gynecology Jersey Shore University Medical Center Neptune NJ USA

Introd.ction: Vaginal birth after cesarean (VBAC) plays an essential role in lowering cesarean rates. d.spite end.rsement, trial of labor after cesarean (TOLAC) attempt rates remain low, in part d.e to fear of lawsuits. Zavanelli maneuver is a last resort proced.re in the management of should.r d.stocia. We d.scuss a case of a woman d.termined.to have a vaginal birth after her prior birth was complicated.by should.r d.stocia requiring a Zavanelli maneuver. Her physicians were reluctant to allow her a TOLAC given her prior obstetric history. Case: A 34-year-old.para 1 with prior cesarean d.livery d.e to should.r d.stocia that required.Zavanelli maneuver presents d.termined.to pursue VBAC in her current pregnancy. She consid.red.her d.livery route options and.ad.ressed.her mod.fiable risk factors. She consulted.with multiple perinatologists who agreed.that a TOLAC was reasonable, however she had.to travel more than 70 miles (from Pennsylvania to New Jersey) to find.an obstetrical practice and.hospital willing to consid.r VBAC. She transferred.care and.the remaind.r of her prenatal course was uncomplicated. She went into labor at 41 weeks and.had.a successful VBAC without complication. In a thank you letter to her obstetrician, she d.scribed.her birth experience as euphoric. Conclusion: This case illustrates how a woman’s choice of d.livery route may be impacted.by fear of litigation. Local provid.rs focused.on her prior d.livery instead.of her overall improved.risk profile. d.livery route d.cisions should.be based.on a thorough evaluation of all risk factors and.ind.vid.alized.to meet the reprod.ctive goals of each woman. .

Localized.states quantum confinement ind.ced.by roughness in Cd.nTe/Cd.e heterostructures grown on Si(111) substrates

Journal of Semicond.ctors 2024年第9期45卷 28-35页

This work shows that d.spite a lattice mismatch of almost 20%, Cd.nTe/Cd.e/Cd.nTe heterostructures grown d.rectly on Si(111) have surprisingly good.optical emission properties. The investigated.structures were grown by molecular beam epitaxy and.characterized.by scanning transmission electron microscopy, macro-and.micro-photoluminescence. Low temperature macro-photoluminescence experiments ind.cate three emission band. which d.pend.on the Cd.e layer thickness and.have d.fferent confinement characteristics. Temperature measurements reveal that the lower energy emission band.(at 1.48 eV)is associated.to d.fects and.bound.exciton states, while the main emission at 1.61 eV has a weak 2d.character and.the higher energy one at 1.71 eV has a well-d.fined.(zero-d.mensional, 0d. 0d.nature. Micro-photoluminescence measurements show the existence of sharp and.strongly circularly polarized.(up to 40%) emission lines which can be related.to the presence of Mn in the heterostructure. This result opens the possibility of prod.cing photon sources with the typical spin control of the d.luted.magnetic semicond.ctors using the low-cost silicon technology.
