Enhancement of system performance using STATCOM as dynamic compensator with squirrel cage induction generator (SCIG) based microgrid
Authors: Saxena Nitin Kumar , Kumar Ashwani , Gupta Varun 
Published: January 2021

Abstract
Value based services are the new emerging area in Indian Electricity Market. Technically, such value added services in the electricity market are known as Ancillary Services. Voltage Control Ancillary Service (VCAS) deals with local level voltage control problem of power sector. According to IEEE standards 1159:1995, 1250:2011, only ±5% voltage variation is allowed with almost 0 deviations in frequency (±0.03% maximum variation limit) to interconnect any new generating plant with a grid. The utilization of squirrel cage induction generators (SCIG) as wind operated micro grid may be in a fix without adequate availability of reactive power. Besides SCIG, load changes also cause voltage varying problems and so, this paper investigates how load change can be coped up with fast acting reactive power compensator for such arrangements. To demonstrate this real time Simulink models for fixed capacitor and STATCOM are developed using MATLAB software. The SCIG starting and load change conditions are tested with fixed capacitor, six and 12 pulse STATCOM as reactive power compensators. The SCIG performances in terms of rotor speed, voltage, and frequency control characteristics during starting of the machine as well as at the time of load perturbation are compared.
Teaching evidence-based practice piece by PEACE
Authors: Emich Cheryl 
Published: January 2021

Abstract
Teaching evidence-based practice (EBP) to nurse practitioner (NP) students creates a challenge. Practicing NPs are frequently called upon to develop EBP protocols and therefore, must be proficient in defining clinical problems, retrieving and appraising evidence, implementing protocols to change practice based on evidence, and evaluating the practice changes. A new faculty team integrated the constructivist approach using the PEACE framework to rebuild the EBP course. Course modules corresponded to each letter of the PEACE framework: problem identification, evidence retrieval, appraisal of evidence, changing practice or conducting more research, and evaluation. Students collaborated with a non-nursing professional as part of the college’s commitment to interprofessional learning. Following the PEACE framework, students created an evidence-based poster of a proposed clinical practice change. Feedback from faculty and students was positive. Areas for improvement included eliminating redundancy in module content, standardizing all grading rubrics, and adding more virtual sessions for student/faculty interaction.
A companding approach for PAPR suppression in OFDM based massive MIMO system
Authors: Yadav Ajay Kumar , Sahoo Pritam Keshari , Prajapati Yogendra Kumar 
Published: January 2021

Abstract
Orthogonal frequency division multiplexing (OFDM) based massive multiuser (MU) multiple input multiple output (MIMO) system is popularly known as high peak-to-average power ratio (PAPR) issue. The OFDM-based massive MIMO system exhibits large number of antennas at Base Station (BS) due to the use of large number of high-power amplifiers (HPA). High PAPR causes HPAs to work in a nonlinear region, and hardware cost of nonlinear HPAs are very high and also power inefficient. Hence, to tackle this problem, this manuscript suggests a novel scheme based on the joint MU precoding and PAPR minimization (PP) expressed as a convex optimization problem solved by steepest gradient descent (GD) with μ-law companding approach. Therefore, we develop a new scheme mentioned to as MU-PP-GDs with μ-law companding to minimize PAPR by compressing and enlarging of massive MIMO OFDM signals simultaneously. At CCDF = 10−3, the proposed scheme (MU-PP-GDs with μ-law companding for Iterations = 100) minimizes the PAPR to 3.70 dB which is better than that of MU-PP-GDs, (iteration = 100) as shown in simulation results.
Cape Town Gujarati and its relation to Gujarati dialectology: A study of retroflex boosting
Authors: Mesthrie Rajend , Chavda Vinu 
Published: January 2021

Abstract
This paper has two purposes. Firstly, it provides a bird’s eye view of the characteristics of a variety of Gujarati in diaspora, viz. that spoken in Cape Town, South Africa for almost 150 years. Secondly it focusses on one notable feature, viz. the prominence of retroflexes over dentals, and connects this with other dialects of Gujarati in India and with Western Indo-Aryan. We analyse the speech of 32 speakers born or brought up in South Africa, and resident in Cape Town. We show that Cape Town Gujarati retains the dialect variation of late nineteenth century Gujarati as identified by Grierson, Sir George A. 1908. Linguistic survey of India. Vol IX, part II: Indo-Aryan family, Central Group – Rajasthani and Gujarati. Delhi: Motilal Banarsidass. In particular, it resembles the Surti dialect, in keeping with the fact that the area around Surat district provided the bulk of migrants to Cape Town in the nineteenth and twentieth century. We then focus in detail on a prominent, but little-studied, phenomenon of Gujarati dialects: the variable occurrence of retroflex stops where Standard Gujarati has dentals [t̪ t̪h d̪ d̪h]. We demonstrate the considerable amount of such “retroflex boosting” in the Cape Town variety. We provide a detailed and replicable methodology from variationist sociolinguistics for studying this boosting that we believe illuminates the study of its occurrence in modern dialects in Gujarat.

LncRNA XIST regulates atherosclerosis progression in ox-LDL-induced HUVECs
Authors: Gao Hongmei , Guo Zhaohui 
Published: January 2021

Abstract
Long noncoding RNAs (lncRNAs) have been verified as vital regulators in human disease, including atherosclerosis. However, the precise role of X-inactive-specific transcript (XIST) in atherosclerosis remains unclear. The proliferation and apoptosis of human umbilical vein endothelial cells (HUVECs) exposed to low-density lipoprotein (ox-LDL) were assessed by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-2H-tetrazol-3-ium bromide, and flow cytometry assays, correspondingly. The western blot assay was used to quantify protein expression. Lactate dehydrogenase activity and the concentrations of inflammatory factors were measured by matched kits. The real-time quantitative polymerase chain reaction (qPCR) was used to determine α-smooth muscle actin, smooth muscle protein 22-α, XIST, miR-98-5p, and pregnancy-associated plasma protein A (PAPPA) levels in HUVECs. The relationship among XIST, miR-98-5p, and PAPPA was analyzed by dual-luciferase reporter, RNA immunoprecipitation, and RNA pull-down assays. We found ox-LDL repressed proliferation and induced inflammation and apoptosis in HUVECs. Loss-of-functional experiment suggested that the downregulation of XIST overturned the ox-LDL-induced effects on HUVECs. Additionally, overexpression of miR-98-5p-induced effects on ox-LDL-stimulated HUVECs was abolished by upregulation of XIST. However, silencing of miR-98-5p strengthened the ox-LDL-induced effects on HUVECs by increasing expression of PAPPA. Mechanistically, XIST could regulate PAPPA expression in ox-LDL-induced HUVECs by sponging miR-98-5p, providing understanding for atherosclerosis.

Uranyl oxalate species in high ionic strength environments: stability constants for aqueous and solid uranyl oxalate complexes
Authors: Xiong Yongliang , Wang Yifeng 
Published: January 2021

Abstract
Uranyl ion, UO2
2+, and its aqueous complexes with organic and inorganic ligands can be the dominant species for uranium transport on the Earth surface or in a nuclear waste disposal system if an oxidizing condition is present. As an important biodegradation product, oxalate, C2O4
2−, is ubiquitous in natural environments and is known for its ability to complex with the uranyl ion. Oxalate can also form solid phases with uranyl ion in certain environments thus limiting uranium migration. Therefore, the determination of stability constants for aqueous and solid uranyl oxalate complexes is important not only to the understanding of uranium mobility in natural environments, but also to the performance assessment of nuclear waste disposal. Here we developed a thermodynamic model for the UO2
2+–Na+–H+–Cl––ClO4
––C2O4
2––NO3
––H2O system to ionic strength up to ∼11 mol•kg−1. We constrained the stability constants for UO2C2O4(aq) and UO2(C2O4)2
2− at infinite dilution based on our evaluation of the literature data over a wide range of ionic strengths up to ∼11 mol•kg−1. We also obtained the solubility constants at infinite dilution for solid uranyl oxalates, UO2C2O4•3H2O, based on the solubility data over a wide range of ionic strengths. The developed model will enable for the accurate stability assessment of oxalate complexes affecting uranium mobility under a wide range of conditions including those in deep geological repositories.

У статті наведено порівняльну характеристику білків рослинного і тваринного походження. Ці добавки застосовують при виготовленні всіх видів м’ясних продуктів, що сприяє розширенню асортименту запропонованих добавок, поліпшенню їхніх функціональних властивостей і підвищенню рівня безпечності. Серед рослинних білків найбільш широко використовують соєві, цільове призначення яких – зниження собівартості готової продукції та стабілізація рецептури. Тваринні білки мають різноманітне походження (колагенові, молочні, плазма крові), це обумовлює різноманітність технологічних процесів і ширший діапазон застосування порівняно з соєвим аналогом. Тим паче повноцінні тваринні білки значно переважають рослинні за біологічною цінністю, краще збалансовані за амінокислотним складом, є добрими емульгаторами, дозволяють переробляти малоцінну жировмісну сировину, покращують консистенцію і пластичність фаршу, підвищують органолептичні властивості готових виробів, збільшують вихід, дозволяють суттєво знизити собівартість продукту. Аналіз останніх досліджень і публікацій свідчить про можливість використання білків м'яса птиці з різних анатомічних частин як гарного структуроутворювача та білкового наповнювача для ковбасного виробництва. Показані композиції, які були створені шляхом компонування тваринного і рослинного білку. Встановлена раціональна масова частка внесення добавки у співвідношенні 80:20 рослинного і тваринного білку відповідно, що дозволяє переробляти малоцінну сировину, покращує консистенцію, пластичність (в’язкість) фаршу, сприяє поліпшенню органолептичних властивостей готових виробів, збільшують вихід, дозволяють суттєво знизити собівартість продукту. Наведено результати впливу даних добавок на функціонально-технологічні властивості та органолептичні показники м'ясних виробів. Показано, що створення композицій шляхом компонування рослинного та тваринного білку у співвідношенні 80:20 має найкращу розчинність та водоутримуючу здатність. Для підтримання сталого pH середовища добавки (створенної композиції) використовували буферні розчини з рН 4,1 та рН 6,55. Розглянуто питання практичного використання білків рослинного і тваринного походження у технологіях виробництва ковбасних виробів із м'яса птиці.

Authors: Rao Shravya S. , Mahendrappa Kotyal B. 
Published: January 2021

Background: Neonatal hyperbilirubinemia is one of the most commonly encountered conditions in neonatal period. Early recognition and prompt intervention can prevent its dreadful complication like bilirubin encephalopathy. nucleated red blood cells (nRBC) are released into the peripheral circulation in conditions causing oxidative stress. This study aims at finding the relation between nRBC and neonatal hyperbilirubinemia. Methods: This hospital based prospective cohort study was conducted on 100 neonates. The neonates were divided into 2 groups: Group 1- cases (n=50) included neonates born to O positive mothers with A/B blood groups and Group 2-controls (n=50) with neonates born to O positive mothers with O blood group. The cord blood nRBC, TSB at 48 hours and requirement of phototherapy were the variables which were considered. Statistical analysis was done using SPSS 22 version software with appropriate statistical methods applied. Results: The mean cord nRBC was 7.26±2.65 (Group 1) and 3.04±0.92 (Group 2) respectively.

Authors: Dudipala Sai Chandar , Mandapuram Prashanthi , Chennadi Amith Kumar 
Published: January 2021

Background: Gratification phenomena (GP) are self-stimulatory behavior and also called as infantile masturbation. This phenomenon is especially seen in early childhood. GP is often misdiagnosed as epilepsy, dystonia, urinary tract infection or infantile colic resulting in numerous investigations and treatment because of variable behaviors during this event.Methods: This study aimed to describe the features of GP, so that clinicians can better recognize this condition, to prevent unnecessary evaluations, and provide appropriate guidance to parents. This study is a prospective observational study, conducted in patients with GP between March 2019 and November 2020. GP was diagnosed on the basis of history, eyewitness account and video recording of the eventResults: During the study period, 19 children were diagnosed with GP. Out of 19, 17(89.4%) children were females. The mean age at onset was 17months (range 5-36months). The mean age at diagnosis was 20 months (range 8-47months). The mean frequency of events was 4/day (range 1-12/day). A typical GP was seen in 12 of 19 (63.15%) children. At the time of referral, 31% of children were diagnosed with epilepsy and 26% of children were diagnosed with infantile colic. During follow up period, GP was subsided within 4-12 months after the initial visit.Conclusions: A GP, otherwise called infantile masturbation, is an important consideration in the differential diagnosis of epilepsy and other paroxysmal events in early childhood. A detailed history and video recording of events often prevents unnecessary investigations and treatments.
Environmental Health Compromised by a New Epidemic. The case of Uruguay, COVID-19
Authors: Gómez- Camponovo Mariana , Achkar Marcel 
Published: January 2021

Uruguay is in South America. It has 3,286,314 inhabitants, 1.6% of which lacks comprehensive health insurance. Detected cases of COVID-19 represent 0.022% of the population, 2.6% of which has resulted in death. Mortality from this illness is 0.6% per 100,000 inhabitants, and health workers represent 14% of detected cases. The country is slowly coming out of intensified social distancing. This article reports on accumulated, recovered, and active cases. The authors also frame the causes of this zoonosis in terms of an environmental health problem, and thus a global health problem, requiring a “one health” approach. Human activity has changed natural habitats as a result of extraction activities, increased urbanization, growing populations, different cultural practices, and socio-economic conditions. This contributes to the emergence of zoonoses, particularly RNA viruses. If the cause of this phenomenon is not addressed, we will continue to face increasingly greater challenges.
