Résumé

Purpose: This study examined the financial contagion between crude oil and gold prices with the equity prices of different sectors in the Indian equity market during the recent COVID crisis. Design/Methodology/Approach: Dynamic conditional correlation (DCC) GARCH model was employed to analyze the behavior of time-varying conditional correlation during the time of COVID-19. For examining the financial contagion, regression analysis was performed on the dynamic conditional correlation and the conditional volatilities of the different markets. Findings: The DCC model showed a sharp increase in correlations between markets during the COVID-19 wave. It also suggested the presence of financial contagion between the crude oil and gold markets and the different equity sectors. It also indicated that the COVID-19 effect on the conditional correlation between gold and equity sectors was temporary. In contrast, it increased the correlation between crude oil and the equity sectors. Practical Implications: The findings of this study have implications for portfolio diversification methods because higher correlations lower the benefits of diversification. Originality: This study examined the financial contagion during COVID-19 from crude oil and gold to equity sectors. Not all sectors react in the same way to changes in the prices of these commodities, and some may witness less impact compared to others during the crisis period, which makes it interesting for the study. © 2023, Associated Management Consultants Pvt.

Résumé

Immunity plays a fundamental role in the maintenance and protection of the human body from infectious and pathogenic microorganisms. It requires regular intake of nutrients for proper functioning of the immune system. Due to an unbalanced lifestyle and consumption of ready-to-eat foods, immunity is being affected negatively. Inflammation and immunity are influenced by diet and nutrition. Simple sugars, trans fats, refined carbs, and processed meat, among other meals, may induce inflammation while simultaneously counteracting the anti-inflammatory benefits of omega-3 fatty acids. As a result, unhealthy food intake may enhance systemic inflammation in individuals, boosting the generation of IL-6. Dietary nutrition is a well-known aspect of immune system maintenance, with the significance of micronutrients prominently featured in a variety of scientific literary works. Currently, global population is susceptible viral infection such as COVID-19. This viral strain is directly attacking the immunity of the individual and bringing it at risk. When a patient's immune system isn't operating correctly, COVID-19 is thought to raise the harshness of the infection or make it more vulnerable to contagious diseases. This review paper will help in understanding the immune responses mechanism along with diet balance and maintaining the sufficiency of vitamins and minerals to fight against COVID-19 infection.Copyright © 2023 The Author(s)

Résumé

The novel coronavirus severe acute respiratory syndrome Corona Virus-2 (SARS-CoV--2) has become a pandemic, as declared by WHO in March 2020 producing deleterious effects on patients worldwide. The angiotensin-converting enzyme-2 (ACE-2) has been recognized as the co-receptor for SARS-CoV-2 infections and may act as a therapeutic step in blocking the enzyme to re-duce SARS-CoV-2 expression and further cellular entry. Presently, the role of ACE-2 in coron-avirus disease 2019 (COVID-19) infection has been known and the experts have started working on the enzyme ACE-2 for the management and treatment of this pandemic disease. The binding of spike (S) protein of SARS-CoV-2 to these receptors is the most important step and plays a key role in viral replication, thus this enzyme is becoming the doorway for the entry and spread in the human body causing asymptomatic pneumonia and severe of which is leading to death. As no specific method to prevent and treat this disease is available, the use of ACE-2 as a targeting ligand with COVID-19 virus spike protein could be helpful in the proper management of SARS-CoV-2 pneu-monia.Copyright © 2021 Bentham Science Publishers.

Résumé

A great deal of work argues that the entry of women into public spaces can promote political and institutional change. The COVID-19 provides an opportunity to investigate whether and under what conditions women's political representation in rural local governments deliver effective local governance? Drawing from two rounds of data collected in 174 local governments and 1051 households in three Indian states, the paper shows that women Pradhans in the Gram Panchayats had no differential impact on the governance response to COVID-19 compared to the unreserved ones. Analyzing the heterogeneity in these responses suggests that institutional factors like the proportion of women in village council and local entrepreneurship diversity can enhance women Pradhan's capacity to respond to the pandemic. We explore two channels that enable women Pradhan to govern effectively during the pandemic: improving women's participation in the labor force and reducing household's vulnerability to poverty in the pre-COVID period. © 2023 John Wiley & Sons Ltd.

Résumé

Introduction Recently, the one-week hypofractionated radiotherapy regimen (26 Gy in 5 fractions) for adjuvant breast radiotherapy has been shown to be non-inferior to other hypofractionated regimens (15-16 fractions). The aim of the present dosimetric study is to compare Intensity Modulated Radiotherapy (IMRT), Volumetric Modulated Arc Therapy (VMAT) and 3D Conformal Radiotherapy (3D-CRT) for a one-week hypofractionated radiotherapy regimen (26 Gy in 5 fractions) for adjuvant breast radiotherapy. Methods A total of 30 patients with histologically proven invasive carcinoma of the breast after breast conservation surgery (BCS) or modified radical mastectomy (MRM) were considered for in silico planning study. The dose prescription used was 26 Gy in 5 fractions as used in the FAST Forward protocol. Targets were contoured according to standard guidelines. The heart, ipsilateral lung, and contralateral breast were contoured as organs at risk. Results Planning Target Volume (PTV) coverage: For IMRT, VMAT and 3D-CRT, respectively, the volumes that received at least 95% of the prescription dose (V95) were 95.7 ± 2.12, 92.47 ± 3.83, 90.87 ± 5.13; mean PTV doses (Dmean) were 26.1 ± 0.6, 25.7 ± 0.7, and 28 ± 4.39 (3D-CRT has higher Dmean compared to other techniques). Maximum PTV doses (Dmax) were 28.23 ± 0.72, 28.73 ± 0.64, and 29.8 ± 1.03. IMRT had a better V95 coverage and conformity index.  Organs At Risk (OARs): The volumes that received at least 25% of the prescription dose (V25) of the heart were 3.41 ± 4.7, 1.8 ± 2.02 and 4.3 ± 6.98 in IMRT, VMAT and 3D-CRT, respectively. The volumetric (V25) comparison of heart dose in left-sided breast cancer was significantly different between VMAT and 3D-CRT (p=0.04, Wilcoxon signed-rank test). The volume that received at least 5% of the prescription dose (V5 ) was less than 25% in the 3D-CRT plan (12.55). For the ipsilateral lung, the V25 parameters were 19.53 ± 10.96, 23.93 ± 13.58 and 20.5 ± 12.32 in IMRT, VMAT and 3D-CRT, respectively. Conclusion From this study, we can conclude that IMRT and VMAT techniques are feasible and can achieve better dosimetric goals for target and OARs though minimizing the area achieving low dose remains to be a dosimetric concern for VMAT.

Résumé

It is well known that the outbreak of infectious diseases is affected by the diffusion of the infected. However, the diffusion network is seldom considered in the network-organized SIR model. In this work, we investigate the effect of the maximum eigenvalue on Turing instability and show the role of network parameters (the network connection rate, the network's infection, etc.) on the outbreak of infectious diseases. Meanwhile, stability of network-organized SIR is given by using the maximum eigenvalue of the network matrix which is proportional to the network connection rate and the networks infection rate. The bridge between the two rates and Turing instability was also revealed which can explain the spread mechanism of infectious diseases. In the end, some measures to mitigate the spread of infectious diseases are proposed and the feasible strategies for prevention and control can be provided in our paper, the data from COVID-19 validated the above results. © Copyright © 2022 EPLA.

Résumé

COVID-19 is one of the most dangerous forms of diseases which is caused by corona virus. It is a highly transmissible disease. WHO has already declared it as a pandemic.Therefore at the current scenario, due to outbreak of this pandemic (COVID-19), face masks has become the necessary tool of everyone to avoid spread of disease to some extent. There has been a great demand for the development of software which can easily recognize person who is wearing a mask. Therefore we are going to develop a system which will fulfill the need using Deep Learning. We will use convolutional neural network to train our model. Here two categories of dataset will be used. The one which contains set of images of faces with mask and the other without face masks We will train the program with this data set to learn to decide whether a person's face is masked or not. OpenCV, tensorflow and keras will be used for the real time face detection with live stream through web camera. After the successful deployment of the product, we will be able to design a software which can be installed at various places such as at the entry gate of colleges, railway stations , air ports , temples, hotels and shops etc. This will easily detect the persons who are entering without face masks by using cameras of the systems. Hence this product is the need of the hour for us to develop so as to work for the safety of humans. © 2021 IEEE.

Résumé

Additive manufacturing (AM) emerged as a boon for the manufacturing systems, due to its capability of producing parts through deposition of materials in a layer-by-layer manner and its effects on the global supply chain by making the systems decentralized in nature. AM is also recognized with various names such as direct digital manufacturing, rapid manufacturing, solid-free fabrication process, and rapid prototyping. It has the potential to make complex and internal lattice structures without any need for prior processing tools as compared with the conventional manufacturing process. Currently, this emerging technology is fulfilling customer demand at a smaller scale. Currently, engineers and research institutes are working on AM-based systems to examine the machine capabilities and microstructural features of manufactured parts in order to fully utilize the potential of the AM process in various organization, research departments, and also at the academic level. This paper provides an overview of AM process, its latent application, combating in COVID-19, and discusses the challenges, which are slowing down its full implementation. © 2021, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

Résumé

In India, very first infection due to Covid-19 was reported by end of January 2020 and, the same has been increased with the span of time. In order to fight the increasing risk among the citizens of nation, the complete lock-down was declared on March 25, 2020 for initially 21 days and thereafter it has been subsequently increased up to its present 4th phase, which would be remain continue until May 31, 2020. First two phases of lock-down were imposed without any relaxation, however, there were gradual relaxation implemented in third and fourth lock-down phases. Air pollution depends on emission of the pollutants from vehicles and industries, as well as dust from construction activities. Due to lock-down, operations concerning these activities were completely shut down. The effect of lock-down on PM2.5, PM10, NO2, SO2, CO and AQI level was studied and comparison of PM2.5, PM10, NO2, SO2, CO and AQI during lock-down with same dates of previous year was also considered.

Résumé

Objectives: To identify evidence on the Quality of life measures and potential interventions in patients diagnosed with COVID-19. Methods: A systematic literature review was conducted based on a reproducible search strategy designed to identify HRQoL outcomes in COVID-19 patients. Evidence indexed in Embase/MEDLINE (until 30th June 2020) and clinical trials.gov (until 8th July 2020) was screened for inclusion per pre-defined criteria. Results: 621 abstracts were screened followed by an evaluation of 91 full text citations. 10 studies were finally included and analysed. Among included studies, a study conducted in China investigated the effect of respiratory rehabilitation on pulmonary function, functional status (6-minute walk distance), QoL (SF-36 scores), functional independence and mental status (Self-rating depression and anxiety scales) in elderly patients. The QoL scores showed statistically significant improvement in the patients receiving respiratory rehabilitation besides improvement in the anxiety associated with COVID-19 diagnosis and isolation. Another study investigated the effect of progressive muscle relaxation (PMR) on anxiety and sleep quality and reported significant improvement in sleep quality and anxiety scores based on sleep state self-rating scale (SRSS) and Speilberger State-trait Anxiety scale (STAI). A case report examined the benefits of DBT (Dialectical behavior therapy) based psychological intervention on a pregnant patient and reported improvement in psychological features with reduction in HAMD-17 (Hamilton Depression scale 17), HAMA (Hamilton Anxiety scale) and MADRS (Montgomery-Asberg Depression rating scale) scores. Other ongoing studies Investigated interventions like pulmonary physiotherapy, pulmonary and motor rehabilitation, post discharge tele rehabilitation (resistive training, breathing and aerobic exercise) and behavioral interventions. A majority of these involved EuroQoL assessment. Conclusions: COVID-19 is unfolding as a complex illness affecting multiple organs with currently unknown long-term effects. Interventions aimed at managing physical and mental QOL measures are necessary particularly in hospitalized patients. These interventions need to be potentially combined with hospitalization and post discharge management protocols.
