A Translation Criticism; Eda: An Anthology of Contemporary Turkish Poetry
Authors: USLU Muazzez
Published: April 2021

This study intends to present the readers of Turkish Poetry in English a translation criticism of Eda: An Anthology of Contemporary Turkish Poetry. The editor-translator, Murat Nemet-Nejat, positions the mystic Sufistic essence of Turkish literature, the legacy of Divan Poetry, to the core of contemporary Turkish poetry in the paratextual material. This claim is an overgeneralization because it underestimates other influences. Moreover, a comparative analysis of the source poems to the translations indicated that contrary to his overemphasis, the translator does not display close thematic or formative renderings of the poems that contain the Sufistic “essence” which he calls “eda”. Rather, the characteristic Sufistic elements are eliminated and poems are manipulated to such an extent that will not escape a postcolonial criticism. Shortly, the anthology offers the readers a rewriting that provides the readers with a distorted representation of Turkish poems in an orientalist alignment embellished with homoerotic images.

Authors: Zarubin A. A. , Filippov E. S. , Vanyarkina A. S. , Ivanova O. G. , Shishkina A. A.
Published: April 2021

Background.Newborninfants who have undergone severe birth asphyxia have a high risk of neurological disorders and death. The most effective method for the treatment of hypoxic ischemic encephalopathy caused by intrapartum asphyxia is therapeutic hypothermia, or targeted temperature management. Currently, there are no large studies comparing its different methods, therefore theaim of our studywas to compare the effectiveness of device-induced and uncontrolled therapeutic hypothermia in newborn infants who underwent intrapartum asphyxia.

Materialsand methods.Studydesign:weconducteda retrospective, longitudinal, cohort study in 39 newborn infants born in severe asphyxia and receiving uncontrolled therapeutic hypothermia (group 1), and in 48 newborn infants born in severe asphyxia and receiving device-induced therapeutic hypothermia (group 2). Statistical data processing was carried out using standard techniques.

Results.The body temperature in newborn infants of both groups was reduced to 33.5 °C within the first hour, but when using uncontrolled therapeutic hypothermia, the body temperature fluctuated from 32 to 35 °C. Device-induced therapeutic hypothermia has a more effective neuroprotective effect as compared to uncontrolled hypothermia (p< 0.05) and more rapidly stabilizes metabolism in newborns due to a decrease in lactate levels (p < 0.05). In newborns device-induced therapeutic hypothermia stabilizes hemodynamics more quickly compared to uncontrolled therapeutic hypothermia (p < 0.05). Device-induced therapeutic hypothermia reduces the period of hospitalization in the neonatal intensive care unit (p < 0.05), the risk of cerebral edema (p < 0.05) and of the repeated episodes of seizures (p < 0.05).

Conclusion.Using uncontrolled therapeutic hypothermia causes a high risk of unintentional fluctuations in rectal temperature towards both hypothermia and rewarming, which can aggravate the severe condition of newborn infants. Device-induced therapeutic hypothermia has a more effective neuroprotective effect.

Published: April 2021

Background. Tick-borne encephalitis virus is dangerous and widespread pathogen that is transmitted to humans through the bites of hard ticks. Wild fungi, such as xylotrophic basidiomycetes, are widely used in traditional medicine to treat the infectious diseases and are promising natural sources of new antiviral agents. It was previously shown that aqueous extracts from the mycelium of the Inonotus rheades (Pers.) P. Karst. (1882) fungus exhibit significant antiviral activity against tick-borne encephalitis virus, however, the mechanisms of this activity remain unclear.

Aim. To analyze the relationship between the virucidal properties of I. rheades extract and the substrate on which the cultivation was carried out.

Materials and methods. The mycelium was grown either in a standard liquid medium with wort or on wooden disks from birch. Extracts of water-soluble polysaccharides were prepared from both mycelium samples. The concentration of infectious tick-borne encephalitis virus was determined using the method of titration of plaque-forming components (PFU). Approximately 30 000 PFU of tick-borne encephalitis virus was mixed with an equal volume of corresponding I. rheades extract at concentration of 8 mg/mL and incubated for 30 min at 37 °C. Afterwards, the residual infectivity of tick-borne encephalitis virus was determined using the identical virus sample incubated with sterile water as a reference.

Results. It was found that treatment of tick-borne encephalitis virus with extracts from I. rheades mycelium resulted in inhibition of the infectivity of the virus in the cell culture. However, the same strain of I. rheades, grown on medium with wort, did not exhibit antiviral properties.

Conclusions. Virucidal substances are likely to be not the main metabolites of the mycelium of I. rheades, but are rather metabolized wood polysaccharides. Further research is needed to more accurately identify the active ingredients and assess their antiviral activity.

Проведено нестационарное численное моделирование формирования и развития пульсационной неустойчивости при горении стехиометрической метановоздушной смеси в зернистом слое на поровом масштабе. Показано, что рассматриваемому процессу присуща значительная пространственная вариация определяющих параметров от канала к каналу как результат локально-неоднородных условий течения и теплообмена вследствие неравномерности укладки частиц слоя. Фронт горения имеет очаговую, фрагментированную структуру с точками якорения на поверхности частиц. Механизм возникновения и развития пульсационной неустойчивости связан с периодически повторяющимся процессом угасания и поджига в поровом канале с градиентом температуры. При уменьшении скорости подачи смеси ниже некоторого критического значения некоторые фрагменты фронта теряют устойчивость, причем чем ниже скорость, тем большая часть фронта становится подверженной пульсациям вплоть до момента, когда неустойчивость начинает охватывать всю расчетную область. Наличие таких перемежающихся режимов определяется локально-неоднородными условиями течения и теплообмена вследствие неравномерности укладки частиц слоя. В процессе развития неустойчивости наблюдается взаимное гидродинамическое влияние очагов неустойчивости в смежных поровых каналах, что может приводить к неупорядоченной частотной характеристике пульсаций.

Выполнены расчетно-экспериментальные исследования по доводке конструкции макета-демонстратора (МД) детонационного прямоточного воздушно-реактивного двигателя (ДПВРД), использующего водород в качестве горючего. Доводочные работы с применением вычислительной технологии ФИЦ ХФ РАН были направлены на повышение устойчивости воздухозаборного устройства (ВЗУ) при М = 2,0, снижение аэродинамического сопротивления и повышение тяговых характеристик МД ДПВРД. Изготовлен новый вариант МД и проведены его огневые испытания в импульсной аэродинамической трубе (АТ) при числах Маха набегающего воздушного потока М = 1,5, 2,0 и 2,5. Важнейший результат огневых испытаний-значительное повышение тяговых характеристик нового варианта МД по сравнению со старым вариантом МД. Так, при M = 1,5 увеличение полной тяги и удельного импульса по топливу достигало 200 Н и 1100 с соответственно, а при М = 2,0-400 Н и 1300 с соответственно. Кроме того, при М = 2,0 значительно расширена область устойчивой работы камеры сгорания (КС) с непрерывно-детонационным горением водорода: от значения коэффициента избытка воздуха (КИВ) ~ 1,6 до ~ 3,3, причем при КИВ = 3,1 значение удельного импульса достигало ~ 4760 с. При M = 2,5 в ДПВРД данного типа впервые получен устойчивый непрерывно-детонационный рабочий процесс. Максимальные значения полной тяги и удельного импульса в испытаниях с M = 2,5 составили 1160 Н и 3780 с соответственно.

В 1960-х гг. Глухарёвым Е. М. был разработан эжекторный пульсирующий воздушно-реактивный двигатель (ПуВРД) с целью его применения для вращения вертолетного винта. Взяв за основу эту конструкцию двигателя, авторы развили ее дальше. В итоге был сделан двухконтурный эжекторный ПуВРД, способный в некоторых случаях переходить в режим, близкий к циклической детонации или квазидетонации и работать в области сверхзвуковых скоростей. В статье вкратце описан принцип работы двигателя с механизмом перехода в режим циклической детонации и один из эффективных методов форсирования его за счет осуществления частичной конверсии топлива, совершаемой в процессе рабочего цикла двигателя при работе на дефлаграционном горении.

Изучено влияние катализаторов горения в сочетании с углеродными нанотрубками (УНТ) на скорость горения топлива, в котором в качестве связующего используется низкокалорийный баллиститный порох (30%), а в качестве окислителя - нитрат аммония (НА) (70%). Показано, что тройной катализатор в сочетании с УНТ оказываетзначительное влияние на горение этого топлива, например при давлении 2 МПа увеличивает скорость горения в 9 раз и снижает значение v от 0,92 до 0,45. Влияние катализаторов резко уменьшается при вводе в состав этого топлива октогена и металлического горючего, что, вероятно, связано со сложностями образования углеродного каркаса на поверхности горения вследствие увеличения температуры в этой зоне и наличия большого количества металлических частиц, затрудняющих доступ реагирующих молекул к катализатору.

Для определения характера влияния цитофлавина в терапевтической концентрации на жизнеспособность лейкоцитов проведено исследование образцов крови 30 пациентов с ишемической болезнью сердца. Лейкоциты из цельной крови выделяли с помощью микропипетки, смешивали с питательной средой RPMI, в опытные лунки добавляли цитофлавин в концентрации, близкой к терапевтической и пробы инкубировали в течение 3 ч в инкубаторе с 5 % содержанием СО2 при температуре 37 °C, затем пробы окрашивали флуоресцентными красителями (Mito TrackerTM Red CMXRos, Calcein AM, Ethidium bromide) и снова инкубировали при тех же условиях ещё в течение 30 мин. Результаты детектировали методом флуоресцентной микроскопии при помощи инвертированного флуоресцентного микроскопа EclipseTi-U (Nikon, Япония) и анализировали с помощью специализированного программного обеспечения EZ-C1 Free Viewer Ver 3.90. Оценивали интенсивность флуоресценции митохондрий и вычисляли индекс жизнеспособности лейкоцитов по разработанной методике. После введения цитофлавина в пробу с лейкоцитарной взвесью наблюдалось два варианта изменения жизнеспособности клеток: у большинства (80 %) больных отмечено увеличение жизнеспособности лейкоцитов, в среднем, на 60 % (p < 0,001) и у 20 % — тенденция к уменьшению данного показателя, в среднем, на 47 % (p < 0,1). Величина флуоресценции митохондрий изменялась в обоих случаях в сторону увеличения, но без достижения достоверности различий. Достоверной корреляции между показателями жизнеспособности клеток и интенсивностью флуоресценции митохондрий обнаружено не было (коэффициент корреляции составил 0,28, p > 0,05). Цитофлавин у 80 % пациентов с ишемической болезнью сердца способен повышать жизнеспособность клеток (лейкоцитов крови), в среднем, на 60 % и таким образом проявлять цитопротекторный эффект.

Daha sürdürülebilir bir hammadde kullanımı arayışının bir parçası olarak, katı faz fermantasyonu (KFF) araştırmalarıın odak noktası haline gelmiştir. KFF yöntemi, çevre kirliliğine neden olan tarımsal atıkların kullanılmasını sağlar. Bu çalışmada, Bacillus licheniformis VO7 muz, elma, karpuz ve portakal kabuklarının bulunduğu KFF ortamına transfer edildi. Kullanılan tarımsal atıklar arasında maksimum α-amilaz üretimi muz kabuklarının bulunduğu KFF ortamından elde edildi. Maksimum α-amilaz üretimi 50 °C, pH 6.0 ve 24. saatte 1500 μm parça büyüklüğündeki muz kabuklarının bulunduğu ortamdan elde edildi. Bu sonuçlar ele alındığında, tüketim sonucu meydana gelen muz kabuğu atıklarının katı faz fermantasyonunda (KFF) substrat olarak kullanımı ile Bacillus licheniformis VO7’den α-amilaz üretimi, çevresel ıslah süreçlerinde kullanılmak üzere potansiyel bir aday olarak düşünülebilir.
Gear Bending Stress Analysis of Automatic Transmissions with Different Fillet Curves
Authors: LI Gang , GENG Zhi
Published: April 2021

Gear bending strength is a core indicator to indicate reliability and operation performances of automotive transmissions. Fillet curve design of dedendum of gear teeth can improve their bending stress and complex tooth contact perfor-mance. Geometrical parameters of gears are considered important for the varia-tion of stresses in the design of gears. Bending stress analysis has been a key area of research to minimize failure and optimize design. This work presents a finite element (FE)-based analysis method of gear bending stress, which can be used for multiple spatial meshing gear teeth simultaneously. Three-dimensional (3D) models of helical gear with double and single circular fillet curves are estab-lished by using Pro/ENGINEER. By changing of meshing positions of gears, tooth contact analysis results along their paths of contact are obtained. Since FE-based tooth contact analysis are performed based on 3D models, the results of bending stress are reliable and authoritative. It is proved that bending stress of the gear with double circular fillet curves is 1.3~1.5 times as that of the gear with single circular fillet curves, which means that gear with single circular fillet curves has better loading capacity than gear with double circular fillet curves. The study will provide a good method for studying gear bending stress to improve gear de-sign of automotive transmissions.

Smoking causes an increase in cholesterol in the blood. It is well known that tobacco contains nicotine has a considerable influence on the increase of blood lipid levels. Normally, lipids play an important role in all aspects of biological life, but excessive cholesterol causes changes in lipid composition, induces ROS formation and lipid oxidation. This process can also cause damage to proteins and DNA, changing cellular function, which causes tissue damage. This research using  analytic survey, with analytic cross sectional design with 30 subjects. The mean cholesterol level between tobacco smokers is 210.0 mg / dl and electric smokers is 123.73 mg / dl. The average difference in cholesterol levels among smokers was tested using One way ANOVA, p value = 0.000 (p <0.05). The cholesterol level of the tobacco smoker group was significantly higher when compared to the electronic smoker group.

compGeometeR: an R package for computational geometry
Authors: Etherington Thomas R , Omondiagbe O. Pascal
Published: April 2021

Computational geometry algorithms and data structures are widely applied across numerous scientific domains, and there a variety of R packages that implement computational geometry functionality. However, these packages often work in specific numbers of dimensions, do not have directly compatible data structures, and include additional non-computational geometry functionality that can be domain specific. Our objective in developing the compGeometeR package is to implement in a generic and consistent framework the most commonly used combinatorial computational geometry algorithms so that they can be easily combined and integrated into domain specific scientific workflows. We briefly explain the discrete and digital combinatorial computational geometry algorithms available in compGeometeR, and identify priorities for future development.

A Note on Non-deterministic Turing Machine and the "P vs. NP ( P versus NP problem )"
Authors: YANG Zheng-Ling
Published: April 2021

摘要：一个非确定型图灵机NDTM的计算过程，可以相当于其对应的确定型图灵机DTM的幂集。如果接受ZF公理系统的幂集公理，“P对NP”问题最可能的答案是：对于确定型图灵机，P≠NP。可以从另外3个角度对它进行一定的解释。ABSTRACT: The calculation process of a non-deterministic Turing machine (NDTM) can be equipotent to the power set of its corresponding deterministic Turing machine (DTM). If accepting the “Axiom of power set” of the ZF axiom system ( Zermelo–Fraenkel set theory ), the most likely answer to the "P vs. NP" ( P versus NP problem ) is: For a deterministic Turing machine, P≠NP ( P is not equal to NP ). This answer can be explained from three other perspectives.

Pendidik merupakan orang dewasa yang membimbing anak agar si anak tersebut bisa menuju ke arah kedewasaan. Peran orang dewasa di dalam proses pembelajaran sangat penting karena tidak mungkin orangyang belum dewasa mendewasakan orang yang belum dewasa. Sosok pendidik begitu besar dalam proses pembelajaran dalam mendidik, mengajar , membimbing, mengarahan, melatih, menilai, dan mengevaluasi peserta didik, namun selain itu seorang pendidik harus memiliki suatu kasih sayang, kewibawaan dan tanggung jawab terhadap peserta didiknya. Pada prakteknya, ternyata menerapkan kasih sayang, kewibawaan, dan tanggung jawab dalam proses pendidikan tidak mudah, banyak hambatan dan kendala yang dihadapi pendidik, baik berkaitan dengan pemahaman maupun kemampuan pendidik. Untuk itu, kemauan dan ketulusan pendidik dalam menjalankan tugasnya menjadi dasar dalam memahami sifat dan sikap anak didik.

Paralysis by Analysis: Choking, Clutching, and Reinvestment in Competitive Gameplay
Authors: Beres Nicole , Klarkowski Madison , Mandryk Regan
Published: April 2021

Video games frequently invoke high-pressure circumstances in which player performance is crucial. These high-pressure circumstances are incubators for ‘choking’ and ‘clutching’—phenomena that broadly address critical failures and successes in performance, respectively. The eruption of esports into the mainstream has vitalized the need to understand performance in video games, and particularly in competitive games spaces. In this short workshop paper, we present a selection of findings and insights from a full paper (submitted for review) exploring potential mechanisms behind choking and clutching. We find that propensity to choke is positively predicted by trait reinvestment—a predisposition to ‘focus inwards’ in high pressure contexts, reverting to slower ‘declarative’ processing in lieu of more automated ‘procedural’ processing. We also find that propensity to clutch is positively predicted by player experience with competitive gaming. We propose that such findings can be utilized to scaffold and support performance in high-pressure gaming spaces, such as esports.
