Finding God in All Things through Poetry
Authors: Dewi Novita
Published: March 2021

Poetry is a language of devotion. It is the melody that resonates from one’s pure conscience. Being the most important and richest part of our spiritual practice, people read and write poems to help them gain understanding about themselves, each other, and the world around them. Examining world poetry, mainly from America, Indonesia, and Sri Lanka which  tell about the presence of God, this article attempts to find out how God the Creator is present and represented, focusing as it does on the connection between poetry and spiritual exercises. Each of the seven poems under discussion is read by considering Ignatian Spirituality of which the core is “Finding God in All Things”. The selected poems show that God can indeed be found in three main spots. First, God resides in the universe. The presence of God in nature is a common theme shared by the poets discussed. Second, the speakers of the poems find God within themselves. They find God through discretion. Third, some of them find the face of God in that of other people because humans are created in His image. The poems open an awareness that God is present in the sufferings of others. In conclusion, poetry serves as both prayers and spiritual exercises that can improve people’s inner compassion and justice.

Published: March 2021

Bağışıklık sistemi vücudu hastalık yapıcı patojenlere karşı koruyan temel savunma sistemidir. Bu savunma sistemi farklı mekanizmalarla etkili olmaktadır. Bağışıklık sistemi, antijen adı verilen vücudun kalıtsal yapısına yabancı olan her türlü yapıya karşı etki gösterir. Vücuda dışarıdan gelen hastalık etkenleri öncelikle doğal bariyerlerle karşılaşmaktadır. Doğal bariyerleri aşmayı başaran etkenler kemik iliği, timus, lenf bezleri ve dalak gibi özelleşmiş organlarda üretilen savunma hücreleri ile karşılaşır. İlk aşamada makrofajlar ve fagositler devreye girer daha sonraki aşamada ise B ve T lenfositleri sürece dahil olurlar. B lenfositlerinden salgılanan antikorlar bağışık sisteminin en önemli savunma mekanizmalarından birini oluşturmaktadır. Antikor moleküllerinin vücudun savunmasındaki bu önemi bilim insanlarını bu alanda çalışmaya yöneltmiştir. Bu doğrultuda 1975 yılında Georges Köhler ve Cesar Milstein, koyun alyuvarları ile immunize ettikleri farelerin B lenfositleri ile fare myeloma hücrelerini birleştirerek oluşturdukları hibrit hücreler ile yeni bir tedavi stratejisinin kapısını açmışlardır. Bu hibrit hücreler sadece istenen antijene bağlanan monoklonal antikor sentezleyebilme yeteneğine sahiptir. Monoklonal antikorlar tıp dünyasında hastalıkların teşhisi, tedavisi ve biyokimyasal analizler gibi birçok alanda kullanmaktadır. Günümüzde hala monoklonal antikora dayalı tedavi ve tedavi seçenekleri üzerinde çalışmalar devam etmektedir. Bu derlemede monoklonal antikorlar ve tedavide kullanımı üzerine genel bilgiler verilecektir.

Published: March 2021

Bu çalışma bıldırcın rasyonlarına farklı seviyelerde multi-enzim ilavesinin yumurtlayan bıldırcınların performans, yumurta iç ve dış kalite parametreleri ile bazı serum parametreleri üzerine etkilerinin değerlendirilmesi için yürütülmüştür. Denemede 10 haftalık yaşta toplam 96 adet Japon bıldırcını dört tekerrürlü altı muamele grubuna ve her bir alt grupta dört bıldırcın olacak şekilde rastgele dağıtılmıştır. Mısır-Soya fasulyesi küspesine dayalı bazal rasyona 100, 500, 1000, 1500 ve 2000 mg/kg multi-enzim ilave edilerek toplamda 6 adet rasyon hazırlanmıştır. Deneme sonuçlarına göre rasyona farklı seviyelerde multi-enzim ilavesinin canlı ağırlık değişimi, yumurta verimi, yumurta ağırlığı, yumurta kitlesi, yem tüketimi ve yemden yararlanma oranına etkisi istatistiki olarak önemsiz olmuştur. Buna ilaveten, muamelelerin kabuk kalınlığı haricinde yumurta iç ve dış kalite parametrelerine etkisi de önemsiz olmuştur. En yüksek yumurta kabuk kalınlığı 1000 mg/kg multi-enzim seviyesinde elde edilmiştir. Serum parametrelerinden glukoz, kreatinin ve kolesterol etkilenmezken AST 100 mg/kg seviyesinde ve albümin, globülin, total protein, kalsiyum ve fosfor konsantrasyonları 2000 mg/kg seviyesinde multi-enzim ilavesinde en yüksek değere ulaşmıştır. Bu sonuçlara göre rasyona yüksek seviyede (2000 mg/kg) multi-enzim ilavesinin bıldırcınların serum parametrelerini iyileştirdiğini, ancak serum parametrelerindeki bu iyileşmenin bıldırcınların performans ve yumurta kalitesine yansımadığı görülmüştür.

Published: March 2021

Türkiye, 2011’den beri devam eden Suriye iç savaşından sosyal, siyasi ve iktisadi olarak en çok etkilenen ülkelerin başında gelmektedir. Ülkeye geçici koruma statüsü altında kabul edilen ve sayıları 3,5 milyonu aşan sığınmacıların işgücüne katılması, çeşitli sosyal, iktisadi ve akademik tartışmaları da beraberinde getirmiştir. Suriyelilerin sosyal ve kültürel entegrasyonu, kamu harcamalarına ve makro iktisadi düzene etkileri, çalışma yaşamına katılmaları ve yerleştikleri bölgelerde arz-talep dengesini değiştirmeleri gibi konular bu tartışmaların odağında yer almaktadır. İşletme yönetimi bakış açısıyla gerçekleştirilen bu çalışmanın amacı Suriyeli sığınmacılar ile aynı işyerinde çalışan Türk işçilerin, sığınmacılara karşı tutumlarını ölçmektir. Bu bağlamda öncelikle Suriyeli sığınmacıların ülkemizdeki statüsüne ilişkin kavram karmaşası giderilmiş, daha sonraki aşamada ise İstanbul ve Bursa’daki sanayi bölgelerinde, işyerinde sığınmacı çalışanlar olduğunu bildiren mavi yakalı işgücü ile nicel perspektiften bir alan araştırması gerçekleştirilmiştir. Araştırma sonuçlarına göre, Türk çalışanların sığınmacıların etnik kökeni ve dinlerine yönelik negatif ve ayrıştırıcı bir tutumu bulunmamaktadır. Bununla birlikte sığınmacıların kültürel entegrasyonu ve makro iktisadi katkıları konusunda kayda değer çekinceler gözlemlenmiştir. İşletme performansının arttırılması, çalışma barışının ve pozitif örgüt ikliminin sağlanması ve yerel işgücü ile sığınmacıların iş birliği içerisinde çalışabilmesi için işletme yöneticileri ve politika yapıcıların üzerine önemli görevler düşmektedir.

A Deliverability Method for Estimating Stabilized Gas Well Performance during Transient Periods on Unconventional Reservoir
Authors: Yasutra Amega , Orliando Calvin
Published: March 2021

This study discusses the determination of the stabilized flow coefficient, C, in the Rawlins and Schellhardt equation. It is applicable in the reservoir with low porosity and permeability model, usually found in unconventional reservoirs. In determining the flow coefficient, a deliverability test method proposed by Hashem and Kazemi was used during the transient flow period of a gas well. Besides, in determining the deliverability exponent, n, used in the least squared analysis equation derived by Johnston and Lee in the determination of C stabilized so that from each value of n, there will be supporting data for determining stabilized flow coefficient. Finally, the application and previous method will determine the flow coefficient value based on reservoir model time stabilization. Later it compares with the John Lee equation and IPR constructs from the model and John Lee.
Interfacially-Adsorbed Particles Enhance the Self-Propulsion of Oil Droplets in Aqueous Surfactant
Authors: Cheon Seong Ik , Batista Capaverde Silva Leonardo , Khair Aditya , Zarzar Lauren
Published: March 2021

We have demonstrated that adsorption of silica nanoparticles at the interface of a solubilizing oil droplet in surfactant solution can significantly accelerate the droplets’ self-propulsion speed. Using fluorescent particle visualization, we correlated the degree of particle surface coverage on bromodecane droplets to the droplet speed in TX surfactant. Slowest speeds were found at the lowest and highest surface coverages and the fastest speeds were achieved at intermediate surface coverages of about 40%. The particle-assisted propulsion acceleration was further demonstrated in nonionic, anionic, and cationic surfactants and a range of oils with varying solubilization rates. We propose that particles at the droplet interface hinder solubilization by displacing oil-water interfacial area, providing asymmetry in the distribution of oil-filled micelles along the droplet surface and accelerating Marangoni flow. We describe a fluid-mechanical model to rationalize the effect of the particles by considering the effect of a non-symmetrical distribution of solubilized oil at the droplet surface. Approaches by which to modulate the distribution of solubilization across droplet interfaces may provide a facile route to tuning active colloid speeds and dynamics.
Design of an Electron-Withdrawing Benzonitrile Ligand for Ni-Catalyzed Cross-Coupling Involving Tertiary Nucleophiles
Authors: Mills Reginald , Edjoc Racquel , Rousseaux Sophie
Published: March 2021

The design of new ligands for cross-coupling is essential for developing new catalytic reactions that access valuable products such as pharmaceuticals. In this report, we exploit the reactivity of nitrile-containing additives in Ni catalysis to design a benzonitrile-containing ligand for cross-coupling involving tertiary nucleophiles. Kinetic and Hammett studies are used to elucidate the role of the optimized ligand, which demonstrate that the benzonitrile moiety acts as an electron-acceptor to promote reductive elimination over β­-hydride elimination, and stabilize low-valent Ni. With these conditions, a protocol for decyanation–metalation and Ni-catalyzed arylation is conducted, enabling access to quaternary α-arylnitriles from disubstituted malononitriles.
The Effect of Tin Substitution on the Excitonic Properties of Two Dimensional Metal Halide Perovskites

Published: March 2021

With growing interest in the lead-free derivatives of the metal-halide perovskites (MHP), it is imperative to fully understand the contribution of the metal cation to their desirable excitonic characteristics. Here, we explore this question by performing an in-depth spectroscopic and theoretical analysis of phenethylammonium tin iodide ((PEA)2SnI4), a prototypical tin based MHP, and rigorously compare it with its lead counterpart. We elaborate on the origin of multiple excitonic resonances uniquely observed in the linear absorption spectrum of (PEA)2SnI4 at energies about 200-300meV above the primary exciton. By performing calculations based on density functional theory and many- body perturbation theory, we suggest that the excitonic series at these higher energies are composed of electronic transitions from a lower lying valence band. Importantly, the valence band splitting is driven by the octahedral conformations that follow subtle variations in the organic-inorganic interactions within the crystal lattice. We experimentally show that the presence of the higher energy excitonic resonance results in a relatively slow nanosecond component in the formation dynamics of the primary exciton, in addition to the ultrafast phonon-driven hot carrier thermalization. While the presence of such slow relaxation channel for the excitons might be beneficial to many optoelectronic applications, our work suggests its possible control via systematic design of the organic cation. Moreover, our observations indicate that spin-orbit coupling does not play a primary role in the intricate yet crucial changes in the excitonic characteristics imparted by the tin substitution.

Genetic sequencing of the virus suggests that it is a beta coronavirus closely linked to the SARS virus. While most people with COVID-19 develop the only mild or uncomplicated illness, approximately 14% develop a severe disease that requires hospitalization and oxygen support, and 5% require admission to an intensive care unit. In severe cases, COVID-19 can be complicated by acute respiratory distress syndrome (ARDS), sepsis and septic shock, multi organ failure, including acute kidney injury and cardiac injury. Reports of the pattern of Covid symptoms suggest that mild fever, cold and cough are the most common symptoms on an average by 5 days after exposure to the virus. Given the current SARS-CoV-2 (COVID-19) pandemic, the availability of reliable information for clinicians and patients is paramount. There have been a number of reports stating that non-steroidal anti-inflammatory drugs (NSAIDs) and corticosteroids may exacerbate symptoms in COVID-19 patients. There is enough literature to prove that many molecules from plants have shown important therapeutic activity with lesser side effects as compared to conventional medicines. Therefore, the present study is aimed to evaluate Plant extracts of proven antiviral activity, which are described as antipyretics and analgesics in classical Ayurvedic texts for their analgesic & antipyretic effect in laboratory animals. Tab. Febcin formulation was selected.
Covid 19’s Effect on Mental Health
Authors: Raj Laddha
Published: March 2021

At times when we are faced with uncertainty, fear of the unknown, anxiety about a new disease, and what could happen can be overwhelming and cause strong emotions, not just in adults but in children as well. Necessary government guidelines, such as social distancing, can make people feel isolated and lonely and can increase stress and anxiety. Though these actions are necessary to reduce the spread of COVID-19, healthily coping with stress will make you, the people you care about, and your community stronger. This prospective study is aimed to assess the impact of the COVID-19 outbreak on mental health and to investigate how the community can remain happy. The one thing which is spreading faster than the infectious disease during the pandemic is the negative energy, with total confirmed cases touching 1 crore, millions of people losing their jobs, and many losing their beloved ones. Awareness regarding mental health is a must. During this phase, there is extremely minimal knowledge about the impact of such epidemics on community mental health. This gap in knowledge means we are less prepared, critically ill-equipped to support communities as we face unprecedented times. In situations like these, all of us have to come forward. It is our responsibility how we handle this, our include both the government and each and every citizen of the country.

Published: March 2021

This study assessed the probable effects of Ethanolic extract of Tanacetum parthenium (EETP) whole plant as hepatoprotective compound that acts on damaged liver due to administration of Sodium arsenite (NaAsO2  — 3mg/kg) in Wistar albino rats for a period of 28 days which results in alteration in Lipid peroxidation, antioxidant enzymes, biochemical factors, and liver enzyme. 30 animals were utilized for the study and are divided into five groups containing 6 rats each. Group –I treated as control received water, Group II-V were treated with sodium arsenite. Group-III received Vitamin-E (reference drug), Group IV treated with EETP 200 mg/kg dose and Group V treated with 400 mg/kg dose after hepatotoxicity induced by Sodium arsenite. Safeguarding effects of Ethanolic extract of Tanacetum parthenium whole plant were screened by analysis of the parameters like alanine transaminase, aspartate transaminase, alkaline phosphatase and total bilirubin, malondialdehyde, antioxidant enzymes. It was explored that administration of EETP at different doses could significantly decrease the enzymatic measures of AST, ALP, ALT, and TB concentration and increase catalase, GSH, GR and GPx levels in comparison with Sodium arsenite-induced control group. The data obtained from this experimental study prefigured the antioxidant potential of EETP and its potential hepatoprotective effects, and its beneficiary therapeutic effects on vandalization or disfigurement of liver due to Sodium arsenite induction in experimental animals.

Published: March 2021

Wire cost and ac loss are paramount issues for the future uptake of high-temperature superconductor (HTS) ac machines. In particular, new approaches which reduce the total manufacturing cost of HTS coils are critical to the future commercial uptake of HTS technology. Here, we present the results of ac loss measurements of a hybrid HTS coil assembly comprising end windings (EWs) wound with BSCCO wire and a central winding (CW) wound with REBCO wire. As a cost mitigation measure, we have chosen to use REBCO wire which possesses a relatively low self-field Ic at 77 K, equating to approximately half that of the BSCCO wire. Transport ac loss measurements were made on the total coil assembly at both 77 K and 65 K, using a recently developed lockin amplifier approach. We show the ac losses in the assembly at these temperatures scale with the overall transport critical current threshold of the hybrid coil assembly. The results are then compared with a reference coil assembly having similar geometrical dimensions, and in which both the EWs and CW were wound with identical BSCCO wire. Surprisingly, we observe that the ac loss of the hybrid coil is lower than that of the BSCCO coil, despite the CW of the hybrid coil employing wire a lower overall average Ic. We attribute this effect to the lower ac loss of coated conductor REBCO wire under parallel field, which is the dominant field orientation in the CW region. Based on this observation, we conclude that the hybrid assembly design is a good design strategy for HTS coil assemblies, enabling both wire cost and ac loss to be balanced.

Facile synthesis of Ge1-x Snx nanowires
Authors: Xu Y , Al-Salim N , Lim TH , Bumby Christopher , Cheong S , Tilley RD
Published: March 2021

We report a facile one-pot solution phase synthesis of one-dimensional Ge1-x Sn x nanowires. These nanowires were synthesized in situ via a solution-liquid-solid (SLS) approach in which triphenylchlorogermane was reduced by sodium borohydride in the presence of tin nanoparticle seeds. Straight Ge1-x Sn x nanowires were obtained with an average diameter of 60 ± 20 nm and an approximate aspect ratio of 100. Energy-dispersive x-ray spectroscopy (EDX) and powder x-ray diffraction (PXRD) analysis revealed that tin was homogeneously incorporated within the germanium lattices at levels up to 10 at%, resulting in a measured lattice constant of 0.5742 nm. The crystal structure and growth orientation of the nanowires were investigated using high-resolution transmission electron microscopy (HRTEM). The nanowires adopted a face-centred-cubic structure with individual wires exhibiting growth along either the 111, 110 or 112 directions, in common with other group IV nanowires. Growth in the 112 direction was found to be accompanied by longitudinal planar twin defects.

Critical review of literature: The case of the news and views genre
Authors: Yin Z , Parkinson Jean
Published: March 2021

© 2021 Elsevier Ltd Review genres (e.g., literature review, critical review) are useful for developing students’ abilities to evaluate literature critically; they have been widely used in university contexts as assessment tasks. The ‘news and views’ article is one such review genre which is often included in science journals and which is increasingly used as an assessment task in graduate science courses. Published ‘News and views’ articles provide a synopsis and critique of a research article. Usually written by a senior researcher, they provide a good exemplar of critique. To investigate how ‘news and views’ articles persuade readers of their assessment of published studies, this article analyses the rhetorical moves and stance and engagement markers of published news and views articles. Findings were that moves in news and views articles had similarities with those in both research articles and review genres such as book reviews. Similar stance and engagement resources were used in news and views articles and research articles, but they were more frequent in news and views articles than in research articles. Based on this analysis, pedagogical applications for teaching critical evaluation of literature are discussed.
The discourse of law and the discourse of power in the works by Yury Dombrovsky
Authors: Shevchenko Ekaterina S. , Makarychev Aleksei V.
Published: March 2021

The article is devoted to the study of the discourse of law and the discourse of power in the prose by Y.O. Dombrovsky. The authors have identified a number of aspects of law and power discourses in order to demonstrate how law and power, reproduced in the works by Y.O. Dombrovsky, can interact with socio-cultural realities. The study involved the axioms of law – fundamental legal principles that have developed because of centuries of law practice and have 7become statements that do not require proof. The analysis of a number of law axioms shows that in the totalitarian reality depicted by the author the law axiomatic is distorted, and fundamental legal laws cease to work. Attention was also drawn to the fact that court scenes are abstract in the prose by Y.O. Dombrovsky and the reasons for this absence are analyzed in the article. It was established that the court in his works can be depicted indirectly (through memories, protocols, etc.), but the hero himself does not participate in the court. In the controlled judicial system of the Stalinist period, the court disappears as an unnecessary instance, since the accused is guilty a priori. Due to the lack of a real advocateship in court, the arrested person can only defend himself if he makes a plea deal in order to get a shorter sentence. When studying the discourse of law and the discourse of power, we turned to the theory of speech genres by M. M. Bakhtin. We have identified and analyzed such genres of judicial and law discourse as the genre of interrogation, indictment, lawyer’s speech, arguments of the parties and protocol, as well as such imperative speech genres of power discourse as the genre of order, submission and possession. It was concluded that the characters by Y.O. Dombrovsky can oppose the ideas of stoicism to despotic power.
Onyms in Internet communication and electronic environment: new phenomena and functions
Authors: Zubareva Anastasia V.
Published: March 2021

The development of electronic communication brings to rapid language and speech-communicative changes. These changes make the scientific task of their timely conceptualization urgent. The purpose of this study is to generalize and analyze the research results on the onyms functioning in the electronic environment and Internet communication. The analysis highlights two the main areas of the research that have developed in science to date. The functioning of the proper name in the Internet discourse is the study object of the first group. The Internet environment is mainly a source of language material according to this group research, which is analyzed considering the electronic communications features (its polycode, informality, interactivity). The feature of this group research is that its’ the main object is represented either by specific linguistic phenomena or special types of discourse, while electronic communication is a secondary feature for its highlight. The second research direction involves the study of new onomastic phenomena that owe their existence to the context of the electronic environment and its communicative, pragmatic, and technical features. This research direction implies both the detection of new types of onyms that were generated by Internet communications, and the description of their characteristic semantic, pragmatic, stylistic, and formal grammatical features. A special status among the objects studied in the second direction is given to such a phenomenon as a nickname, which implements a whole set of features that allow us to talk about its principal novelty and uniqueness. A nickname is the result of autonomy in terms of pragmatic and communication. This contributes to its use as a means of self-presentation and expression; also, a nickname has noticeable formal features that represent the ways of its construction (free choice of motivational bases, language play, active use of non-alphabetic characters). There is also noted an impact of new phenomena in Internet onomastics on the onomastic system and emphasized the need for closer attention to this influence.
