Published: December 2020

В работе выполнен анализ примера неисправности ВОД фирмы Caterpillar С32, установленного в качестве одного из главных двигателей судов вспомогательного флота. Наработка двигателя составляет 6 500 часов. Выявлена неисправность охладителя наддувочного воздуха, вследствие чего судно было выведено из эксплуатации. Для подтверждения полученных результатов о текущем состоянии двигателей, принято решение о выполнении частичной разборкидвигателя для проведения его дефектации. Результат дефектации двигателя показывает, что при позднем обнаружении протечки забортной воды, начала прогрессировать коррозия на деталях ЦПГ, куда попала вода. Анализ инструкции по эксплуатациипоказал, что должен выполняться периодический контроль состояния ОНВ. Анализ конструкции и системы охлаждения показал, что на таких типах двигателей устанавливаются два варианта системы охлаждения воздуха: забортной водой и антифризом. Причиной, рассмотренной неисправности двигателя, являлось не соблюдение рекомендаций завода-изготовителя по техническому обслуживанию двигателя. Что повлекло к нарушению плотности сердцевины ОНВ в результате возникновения электрохимической коррозии. А также отсутствие внимания обслуживающего персонала к дренажному клапану, увеличило время прохода забортной воды по системе впуска наддувочного воздуха в камеры сгорания цилиндров. В результате такой неисправности судовладелец понес большие потери, связанные с ремонтном двигателя и простоем судна.
The paper analyzes an example of a caterpillar C32 failure, installed as one of the main engines of fleet vessels. The operating time of the engine is 6 500 hours. The after cooler failure was detected; as a result the vessel was taken out of operation. The results obtained confirm about the current state of the engines, it was decided to perform a partial disassembly of the engine to defecation. The result of engine defects shows that when a late detection of seawater leaks, corrosion began to progress on the parts of the engine. The operating instructions analysis showed that periodic monitoring of the after cooler should be performed. The engine design analysis showed that there two types of air cooling systemengine: seawater and antifreeze. The reason for the engine failurewas non-compliance with the recommendations for engine maintenance. The caused the disruption of the aftercooler core density as a result of electrochemical corrosion. As well as the lack of drain valve attention of service personnel, increased the time of seawater passage through the charge air intake system of cylinders combustion chambers. As a result of this failure, the ship owner has suffered heavy damage related to engine repairs and downtime of the vessel.

Эксплуатации судовых малооборотных дизелей с электронным управлением свидетельствует о том, что со временем появляются повреждения и отказы, связанные с естественными износами пар трения, особенно прецизионных, в силовой гидравлической системе (СГС), топливных насосах высокого давления и форсунках, а также выпускных клапанах с гидравлическим приводом. Фирмы изготовители судовых малооборотных дизелей для улучшения эксплуатационных показателей и повышения ресурсов указанных деталей широко используют новые более износостойкие и жаропрочные материалы, такие как высокоуглеродистые легированные стали, нержавеющие стали, сплавы на основе кобальта – стиллиты, сплавы на основе никеля – нимоники и инконели, в частности для выпускных клапанов. Такое решение позволяет повысить надёжность деталей, увеличить межремонтные периоды и гарантировать более длительный срок службы, одновременно снизив эксплуатационные затраты, несмотря на некоторое повышение стоимости этих деталей. Приведены характеристики указанных материалов ожидаемые и подтвержденные данные об увеличенных межремонтных интервалах.
The operation of low-speed marine diesel engines with electronic control indicates that over time, damage and failures appear associated with natural wear of friction pairs, especially precision ones, in the power hydraulic system, high-pressure fuel pumps and injectors, as well as hydraulically operated exhaust valves.

Published: December 2020

Abstract
Supernova (SN) explosions can potentially affect the structure and evolution of circumnuclear disks in active galactic nuclei (AGN). Some previous studies have suggested that a relatively low rate of SN explosions can provide an effective value of alpha viscosity between 0.1 and 1 in AGN accretion disks within a 1 pc scale. In order to test this possibility, we provide some analytic scalings of the evolution of an SN remnant embedded in a differentially rotating smooth disk. We calibrate our estimates using three-dimensional hydrodynamical simulations where the gas is modeled as adiabatic with index γ. Our simulations are suited to include the fact that a fraction of the momentum injected by the SN escapes from the disk into the corona. Based on these results, we calculate the contribution of SN explosions to the effective alpha viscosity, denoted by α
SNe, in a model AGN accretion disk, where accretion is driven by the local viscosity α. We find that for AGN galaxies with a central black hole of

and a disk with viscosity α = 0.1, the contribution of SN explosions may be as large as

, provided that

. On the other hand, in the momentum conservation limit, which is valid when the push by the internal pressure of the SN remnant is negligible, we find

Introduction: Dirofilaria immitis is a nematode that affects human health in several countries of the world. This study was conducted to examine whether serum samples from the owners of microfilaremic dogs present immunoreactivity to parasite proteins.
Methodology: Eight serum samples from the owners of microfilaremic dogs were examined. Total proteins were extracted from adult worms and 12% SDS-PAGE was performed. The gel was electroblotted to a nitrocellulose membrane, and a Western blot (WB) was performed. Reactive bands of 22, 33, 39, 49, and 63 kDa in WB were excised from the gel and analyzed by mass spectrometry (MS).
Results: The MS results showed the presence of 10 different proteins of D. immitis recognized by the human serum samples.
Conclusions: These results indicate that in endemic areas of D. immitis, owners of infected dogs recognize specific proteins of the parasite, suggesting a possible infection.
Existe-t-il une violence spécifique faite aux femmes ?
Authors: Pingeot Mazarine , de Villeneuve Camille 
Published: December 2020

Le mouvement #MeToo a marqué un tournant décisif dans la prise de conscience des agressions sexuelles dont les femmes sont les victimes. Il a suscité des différends au sein des mouvements féministes, aussi bien sur le fond que sur la forme de certaines affaires soulevées sur les réseaux sociaux, en entraînant dans la presse des échanges de tribunes où les camps s’affrontent souvent de façon irréconciliable. À partir de la tribune publiée par Mazarine Pingeot dans Le Monde , le 28 juillet 2020, et des réactions qu’elle a suscitées, nous lui avons proposé de débattre sous la forme épistolaire avec une autre philosophe, Camille de Villeneuve, qui a analysé le mouvement #MeToo dans les colonnes de la revue Études , en leur soumettant cette question : existe-t-il une violence spécifique faite aux femmes ?
Inhibition of Efferocytosis by Extracellular CIRP–Induced Neutrophil Extracellular Traps

Published: December 2020

Abstract
Phagocytic clearance of apoptotic cells by the macrophages (efferocytosis) is impaired in sepsis, but its mechanism is poorly understood. Extracellular cold-inducible RNA-binding protein (eCIRP) is a novel damage-associated molecular pattern that fuels inflammation. We identify that eCIRP-induced neutrophil extracellular traps (NETs) impair efferocytosis through a novel mechanism. Coculture of macrophages and apoptotic thymocytes in the presence of recombinant murine CIRP (rmCIRP)–induced NETs significantly inhibited efferocytosis. Efferocytosis was significantly inhibited in the presence of rmCIRP-treated wild-type (WT), but not PAD4−/− neutrophils. Efferocytosis in the peritoneal cavity of rmCIRP-injected PAD4−/− mice was higher than WT mice. Milk fat globule–EGF–factor VIII (MFG-E8), an opsonin, increased macrophage efferocytosis, whereas the inhibition of efferocytosis by NETs was not rescued upon addition of MFG-E8, indicating disruption of MFG-E8’s receptor(s) αvβ3 or αvβ5 integrin by the NETs. We identified neutrophil elastase in the NETs significantly inhibited efferocytosis by cleaving macrophage surface integrins αvβ3 and αvβ5. Using a preclinical model of sepsis, we found that CIRP−/− mice exhibited significantly increased rate of efferocytosis in the peritoneal cavity compared with WT mice. We discovered a novel role of eCIRP-induced NETs to inhibit efferocytosis by the neutrophil elastase–dependent decrease of αvβ3/αvβ5 integrins in macrophages. Targeting eCIRP ameliorates sepsis by enhancing efferocytosis.
Coronavirus Receptors as Immune Modulators
Authors: Devarakonda Charan Kumar V. , Meredith Emily , Ghosh Mallika , Shapiro Linda H. 
Published: December 2020

Abstract
The Coronaviridae family includes the seven known human coronaviruses (CoV) that cause mild to moderate respiratory infections (HCoV-229E, HCoV-NL63, HCoV-OC43, HCoV-HKU1) as well as severe illness and death (MERS-CoV, SARS-CoV, SARS-CoV-2). Severe infections induce hyperinflammatory responses that are often intensified by host adaptive immune pathways to profoundly advance disease severity. Proinflammatory responses are triggered by CoV entry mediated by host cell surface receptors. Interestingly, five of the seven strains use three cell surface metallopeptidases (CD13, CD26, and ACE2) as receptors, whereas the others employ O-acetylated-sialic acid (a key feature of metallopeptidases) for entry. Why CoV evolved to use peptidases as their receptors is unknown, but the peptidase activities of the receptors are dispensable, suggesting the virus uses/benefits from other functions of these molecules. Indeed, these receptors participate in the immune modulatory pathways that contribute to the pathological hyperinflammatory response. This review will focus on the role of CoV receptors in modulating immune responses.
A Cross-Sectional Study of the Impact of COVID-19 on Domestic Violence, Menstruation, Genital Tract Health, and Contraception Use among Women in Jordan
Authors: Aolymat Iman 
Published: December 2020

ABSTRACTThe COVID-19 pandemic is a major global concern for public health where high numbers of COVID-19–infected cases and deaths have been recorded. This study assessed the COVID-19 pandemic impact on domestic violence, genital tract health, menstruation, and contraception use among 200 women in Jordan using a self-validated survey questionnaire. The questionnaire was structured to compare frequencies of domestic violence, reproductive tract infections, menstrual irregularities, and contraception use, type, source, and replacement during or after total curfew in Jordan with 6-months before the pandemic; 20.5% of women suffered from increased domestic abuse during the COVID-19 pandemic. Incidence of menstrual problems and genital tract infections was significantly reduced during total curfew compared with 6 months prior (10.5% versus 17.5%; P = 0.016 and 19% versus 25.5%; P = 0.041, respectively). Pre-pandemic state of menstrual problems and genital tract infections was resumed after total curfew. During total curfew, phone consultations were significantly increased (17.5% versus 8.5%; P = 0.01), whereas visiting clinics was significantly reduced (23% versus 5.5%; P = 0.000) to manage menstruation or birth canal infections. Contraception use during total curfew significantly decreased compared with prior (59.5% versus 65.5%; P = 0.017). Using contraception for family planning was reduced significantly during the pandemic than before (P = 0.007). Maternity and childhood centers were more common sources for contraception before than after (14.8% versus 7% or 9.5%; P = 0.001 or P = 0.022). This study is important to evaluate preparedness of Jordanian healthcare systems in facing pandemic situations concerning reproductive health services.
