Ultra mega power plant disturbance related oscillation detection in Indian grid using PMU data
Authors: Kulkarni Amit R. , Ballal Makarand S. 
Published: August 2020

AbstractThe power system oscillations in the grid are an issue of concern to the system operator. They may transform a stable system into an unstable system when the system is operating on the edge and contingency occurs. The oscillations developed in the system may grow and spread across the power grid if no timely, corrective action is taken to mitigate them. The paper presents the ultra-mega power plant generation complex related blackout analysis. The case study presented in this paper demonstrates the utilization of synchrophasor data to have a better realization about the grid disturbance. It covers some of the important dynamic simulation studies considered representative of various scenarios during this. The paper illustrates utilization of Prony analysis using multiple signals and Fast Fourier Transform methods in conjunction with frequency data obtained in real-time from PMUs installed in the western regional grid of India to determine the frequency of oscillations, its magnitude, and related damping during this disturbance. The focus of this study involves the application of these techniques to gain insight into the oscillatory behavior of the system during this disturbance associated with ultra-mega power plant having generation capacity greater than or equal to 4000 MW from the western part of Indian grid. Based on this, distinct categorization of oscillations into “local mode” and “inter-area mode” of oscillations was done for enhanced understanding about the type of oscillations getting excited during this disturbance.
The effect of slight milling on nutritional composition and morphology of quinoa (Chenopodium) grain
Authors: Wu Li-Gen , Wang Anna , Shen Ruilin , Qu Lingbo 
Published: August 2020

Abstract
This study conducted a detailed evaluation of the nutritional value and proximate composition of milled quinoa grain at different dehulling rates with the goal of identifying a range of dehulling rates that retain the maximum level of nutrients and phytochemicals.
Eleven samples of quinoa grain processed at different dehulling rates were obtained through light abrasive milling. The relationship between the dehulling rate and the nutritional composition of quinoa grain was determined. As the dehulling rate increased, the proportions of protein, fat, dietary fiber and ash decreased, whereas the proportion of starch increased. With the increase of dehulling rate, increasing amounts of protein, fat, starch, dietary fiber, saponin, flavonoids, and total phenolic were lost with the hull residue. At the dehulling rates of 8.6%, 11.72% protein, 7.57% fat, 4.72% starch, 28.9% total dietary fiber, 45.5% soluble dietary fiber, 48.58% saponin, 26.18% flavonoid, and 42.25% total phenolic were lost in dehulled quinoa grain compared with the raw quinoa grain. Optical microscope photos and scanning electron microscope (SEM) images showed that only the pericarp of quinoa was scoured when the dehulling rate was below 8.6%, and the quinoa grain retained a complete embryo. Therefore, to retain maximum nutritional and phytochemical content in the quinoa and maintain quinoa grain integrity, it is necessary to limit the dehulling rate of quinoa in the range of less than 8.6%.
Ultradiversities and their spherical completeness
Authors: H. Mehrabani Gholamreza , Nourouzi Kourosh 
Published: August 2020

Abstract
Diversities are a generalization of metric spaces which associate a positive real number to every finite subset of the space. In this paper, we introduce ultradiversities which are themselves simultaneously diversities and a sort of generalization of ultrametric spaces. We also give the notion of spherical completeness for ultradiversities based on the balls defined in such spaces. In particular, with the help of nonexpansive mappings defined between ultradiversities, we show that an ultradiversity is spherically complete if and only if it is injective.

Abstract

Objectives

Rheum ribes L. is a perennial plant that belongs to the family of Polygonaceae, which is often used in traditional therapy because it possesses many bioactivities, such as antioxidant and antibacterial ones. Here we examined the effect of different R. ribes L. extracts on oxidative stress in experimental diabetic rats.

Methods
Thirty-six rats were divided into six groups as follows: group I, control group; group II, diabetic rats; group III, diabetic rats treated with the aqueous extract of R. ribes L. by gavage at 50 mg/kg for 15 days; group IV, diabetic rats treated by gavage with the ethanolic extract of R. ribes L. at 50 mg/kg for 15 days; group V, nondiabetic rats treated by gavage with the aqueous extract of R. ribes L. at 50 mg/kg for 15 days; group VI, nondiabetic rats treated by gavage with the ethanol extract of R. ribes L. at 50 mg/kg for 15 days. After 15 days, the animals were sacrificed and the liver and kidney tissues of each animal were isolated. Superoxide dismutase (SOD), catalase (CAT), malondialdehyde (MDA) and glutathione peroxidase (GSH-Px) activities in the tissue samples were measured, and histopathologic examination was carried out.

Results

R. ribes L. was effective in reducing the oxidative stress and increasing the levels of the antioxidant enzymes. Increased levels of MDA and decreased levels of SOD, CAT and GSH-Px were observed in both the liver and kidney tissues in group II. Decreased levels of MDA and increased levels of SOD, CAT and GSH-Px were observed in group III compared with group II. In group IV, decreased levels of MDA and increased levels of SOD, CAT and GSH-Px were observed in comparison with group II.

Conclusions
Diabetes increases oxidative stress and causes a decrease in antioxidant enzyme levels. Both aqueous and ethanolic extracts of R. ribes L. decrease oxidative stress activity and increase the levels of antioxidant enzymes. The ethanol extract of R. ribes L. has a higher antioxidant effect than the aqueous extract.
Efficacy of Habbul aas (fruits of Myrtus communis) in menorrhagia: a single blinded randomized standard control study
Authors: Umarami Rayeesa Banu R. , Roqaiya Mariyam , Quadri Mohd Aqil 
Published: August 2020

Abstract

Objectives
Menorrhagia can be defined as heavy uterine bleeding which comes at regular intervals or uterine bleeding extending more than seven days during menses which has become a considerable problem for females, causing discomfort, anxiety, and poor quality of life. In this study we aimed to compare the effect of Myrtus communis fruits with tranexamic acid in the treatment of menorrhagia.

Methods
In this prospective patient blinded standard controlled study, 40 patients of menorrhagia were randomly assigned to receive either test drug (powdered M. communis fruits) or active control drug (tranexamic acid) for first five days of menstrual cycle consecutively for two cycles. The primary outcome measure was reduction in heavy flow during menses determined by pictorial blood loss assessment chart (PBAC), while improvements in quality of life (QOL) by using short form-36 questionnaire and increase in hemoglobin percentage were kept as secondary outcome measures.

Results
Both the groups were similar at baseline. Test and control drugs significantly reduced the PBAC score during treatment cycles with p-value <0.001 and these changes were not significantly different between the groups. During second treatment cycle significant difference was found in PBAC score (p = 0.024) between the groups. After treatment significant improvement in hemoglobin percentage was noted and marked improvement in overall quality of life was observed in both the groups.

Conclusion
These data suggest that M. communis fruits can be an effective alternate in reducing heavy menstrual bleeding. There is need to confirm these results by designing a trial on large number of patients.

Evaluation of Basic Trainings for Rescue Forces
Authors: Niemann Lena , Thielsch Meinald T. 
Published: August 2020

Abstract
Since members of rescue forces such as firefighters have to deal with sometimes extreme and dangerous situations, high-quality basic trainings are indispensable for their professional success. There is therefore an obvious need for standardized tools assessing the training quality. This paper aims to develop and validate such an evaluation instrument. In Study 1, a qualitative analysis (N = 21) was used to identify core characteristics of good firefighter basic trainings and served as theoretical basis for the generation of corresponding items. In Study 2 (N = 257), the item set was piloted and reduced, its structure was assessed in exploratory factor analyses, and first validations were conducted. Study 3 (N = 451) tested the proposed factor structure via confirmatory analyses and validated the questionnaire comprehensively. Factor analyses showed a six-factor structure. The scales of the newly created Feedback Instrument for Rescue forces Education – Basic education (FIRE-B) are to be judged as reliable. Moreover, there are several clear indications of validity. Thus, the present research contributes to the understanding of critical factors and processes of basic trainings. Furthermore, the FIRE-B has a high practical relevance, both in the assessment of training quality and in the identification of opportunities for improvement.
Impaired glucose homeostasis and a novel HLCS pathogenic variant in holocarboxylase synthetase deficiency: a report of two cases and brief review
Authors: Wu Hsin-Ru , Chen Kuan-Jung , Hsiao Hui-Pin , Chao Mei-Chyn 
Published: August 2020

Abstract

Objectives
Holocarboxylase synthetase deficiency (HCSD) (OMIM #253270) is a rare inborn error of metabolism with an estimated annual incidence of 1 in 200,000 people. Typical manifestations of HCSD include eczema, alopecia, lactic acidosis and hyperammonemia. Diagnosis is made through genetic analysis.

Case presentation
Patient 1 was a 7-year-old girl with normal growth and development, presenting with severe hypoglycemia and metabolic acidosis. Her family reported that she was diagnosed as having ketotic hypoglycemia; she had five episodes of hypoglycemia and metabolic acidosis in past 4 years when her oral intake decreased during acute illness. Patient 2 was a 6-month-old female infant with normal growth and development, presenting with progressive generalized eczema and metabolic acidosis for the first time. We found that they both had hyperammonemia, hyperlactatemia, hyperketonemia, organic acids detected in urine and elevated C5OH acylcarnitine level by tandem mass spectrometry. HLCS gene analysis showed a homozygous pathogenic variant p.V363D in patient 1 and a pathogenic variant p.R508W compound with a novel splice site pathogenic variant c.2010-1G>A in patient 2. They have been on biotin treatment (10 mg/day for both of them) for more than 2 years and no more symptoms have occurred.

Conclusions
HCSD is a rare disease, and it can be fatal if severe metabolic acidosis occurs without timely management. Once the diagnosis is made, most of the patients with HCSD have good prognosis and normal life expectancy with biotin treatment.

Abstract

Objectives
Established reference intervals of thyroid function in neonates are important; however, studies often consist of a small sample size or lack of clinical information. We aim to define reference intervals for thyroid-stimulating hormone (TSH) and free thyroxine (FT4) for infants aged 14–30 days. We also reviewed follow-up TSH for infants with initial values 10–20 mIU/L.

Methods
Venous TSH and FT4 of term babies aged 14–30 days with breast milk jaundice that had thyroid function test performed as part of a prolonged jaundice workout from September 2016 to March 2017 were analyzed. Electronic medical records were reviewed to ensure only well babies with no pathological causes of jaundice or conditions that may affect thyroid function were included. TSH and FT4 were analyzed using immunoassay analyzer Dxl 800, Beckman Coulter.

Results
There were no correlations between FT4 and TSH with gender, birth weight and ethnicity. Correlation coefficient between FT4 and total bilirubin was weak at 0.138 (p=0.001). No association was found between TSH and bilirubin levels. Mean FT4 was higher in the younger age group day 14–21 (p<0.01). There was no significant difference in TSH values between the age groups. Infants with mildly elevated TSH 10–20 mIU/L had normalized values on follow-up (mean, 11.41 vs. 4.42 mIU/L; p<0.01; 95%CI, 5.88–8.09). The following reference intervals (2.5–97.5th percentile) were derived: FT4 day 14–21 (n=513): 11.59–21.00 pmoL/L; FT4 day 22–30 (n=66): 10.14–19.60 pmoL/L; TSH day 14–30 (n=579): 1.90–10.34 mIU/L. Comparison between studies showed variations of reference intervals with different manufacturer assays, age and methodology.

Conclusions
Our reference intervals would be useful in the clinical setting. Infants with mildly elevated TSH could be monitored first instead of immediate treatment.
Killing a Constitution with a Thousand Cuts: Executive Aggrandizement and Party-state Fusion in India
Authors: Khaitan Tarunabh 
Published: August 2020

Abstract
Many concerned citizens, including judges, bureaucrats, politicians, activists, journalists, and academics, have been claiming that Indian democracy has been imperilled under the premiership of Narendra Modi, which began in 2014. To examine this claim, the Article sets up an analytic framework for accountability mechanisms liberal democratic constitutions put in place to provide a check on the political executive. The assumption is that only if this framework is dismantled in a systemic manner can we claim that democracy itself is in peril. This framework helps distinguish between actions that one may disagree with ideologically but are nonetheless permitted by an elected government, from actions that strike at the heart of liberal democratic constitutionalism. Liberal democratic constitutions typically adopt three ways of making accountability demands on the political executive: vertically, by demanding electoral accountability to the people; horizontally, by subjecting it to accountability demands of other state institutions like the judiciary and fourth branch institutions; and diagonally, by requiring discursive accountability by the media, the academy, and civil society. This framework assures democracy over time – i.e. it guarantees democratic governance not only to the people today, but to all future peoples of India. Each elected government has the mandate to implement its policies over a wide range of matters. However, seeking to entrench the ruling party’s stranglehold on power in ways that are inimical to the continued operation of democracy cannot be one of them. The Article finds that the first Modi government in power between 2014 and 2019 did indeed seek to undermine each of these three strands of executive accountability. Unlike the assault on democratic norms during India Gandhi’s Emergency in the 1970s, there is little evidence of a direct or full-frontal attack during this period. The Bharatiya Janata Party government’s mode of operation was subtle, indirect, and incremental, but also systemic. Hence, the Article characterizes the phenomenon as “killing a constitution by a thousand cuts.” The incremental assaults on democratic governance were typically justified by a combination of a managerial rhetoric of efficiency and good governance (made plausible by the undeniable imperfection of our institutions) and a divisive rhetoric of hyper-nationalism (which brands political opponents of the party as traitors of the state). Since its resounding victory in the 2019 general elections, the Modi government appears to have moved into consolidation mode. No longer constrained by the demands of coalition partners, early signs suggest that it may abandon the incrementalist approach for a more direct assault on democratic constitutionalism.

Published: August 2020

Abstract
Ultrasonic irradiation has been adopted in order to achieve an efficient synthesis of some novel α-aminophosphonates by Pudovik reaction. Major benefits of this method are as follows: eco-friendly, free of catalyst, high yielding, uncomplicated work-up procedure, short reaction time, and solvent free condition. Spectral characterisation and elemental analysis of the synthesized samples was carried out. In vitro antioxidant activity of the title compounds was screened by DPPH˙, O2-˙ and NO˙ scavenging methods. Good activity was shown by most of the compounds as compared with the standards.
Public health messages about COVID-19 prevention in multilingual Taiwan
Authors: Chen Chun-Mei 
Published: August 2020

Abstract
In this paper, I explore multilingual preventative public health messages against the spread of COVID-19 in Taiwan between January and April 2020. Based on empirical data, the symbolic and substantive content of multilingual top-down and bottom-up public health strategies was analyzed and discussed. Findings suggest that the voices of indigenous people have largely been excluded from top-down efforts and strategies in public health communications. Top-down communication did not address the actual concerns of indigenous populations who relied on tourism to bolster their economy. Bottom-up efforts emerged from social exclusion and the inaccessibility of public health information to indigenous populations; such efforts were over-communicated, and the problems of indigenous populations remained unaddressed. I conclude by relating multilingualism and the needs of minority groups, and suggest an inclusive approach to social challenges and solutions for future pandemic preparedness.
Linguistic diversity in a time of crisis: Language challenges of the COVID-19 pandemic
Authors: Piller Ingrid , Zhang Jie , Li Jia 
Published: August 2020

AbstractMultilingual crisis communication has emerged as a global challenge during the COVID-19 pandemic. Global public health communication is characterized by the large-scale exclusion of linguistic minorities from timely high-quality information. The severe limitations of multilingual crisis communication that the COVID-19 crisis has laid bare result from the dominance of English-centric global mass communication; the longstanding devaluation of minoritized languages; and the failure to consider the importance of multilingual repertoires for building trust and resilient communities. These challenges, along with possible solutions, are explored in greater detail by the articles brought together in this special issue, which present case studies from China and the global Chinese diaspora. As such, the special issue constitutes not only an exploration of the sociolinguistics of the COVID-19 crisis but also a concerted effort to open a space for intercultural dialogue within sociolinguistics. We close by contending that, in order to learn lessons from COVID-19 and to be better prepared for future crises, sociolinguistics needs to include local knowledges and grassroots practices not only as objects of investigation but in its epistemologies; needs to diversify its knowledge base and the academic voices producing that knowledge base; and needs to re-enter dialogue with policy makers and activists.
