ABSTRACT

Student learning through online tools during the pandemic covid-19 situation has been studied and reported in this paper. Students pursuing engineering under graduation and business management post graduation were given a Google form to respond to questions related to type and kind of online platform used, difficulties in teaching-learning, expectations of students etc. Suggestions were invited for better learning online. This paper presents the results of the feedback of students on technical and non-technical issues during online learning. The online environment is sub-divided into four broad categories viz., technological, personal, teaching aids and learning management system. Influence of these parameters on effectiveness of online teaching and feedback from students are discussed. Students had difficulties in internet network, bandwidth, clarity of audio-visual, interruptions in power supply, wifi-networks, poor infrastructure and affordability. 57 percent of respondents are dependent on mobile phone instruments for online class work. Majority of students felt that online certification courses can reduce burden to some extent. The results can be used for designing better online tools for effective online learning for students. © 2023, Rajarambapu Institute Of Technology. All rights reserved.

ABSTRACT

Background: Kidney transplant recipients (KTRs) are deemed to be at a high risk of severe coronavirus disease (COVID-19). Herein, we describe the clinical, laboratory profiles, management, and outcomes of 26 KTRs who developed COVID-19 during the first and second waves of the pandemic from a tertiary care center in northern India. Methods: This retrospective observational study included KTRs detected with COVID-19 infection during the first wave (March-November 2020) and the second wave (March-July 2021). Their clinical and laboratory investigations, management aspects, and outcomes were compared, using data retrieved from clinical and telenephrology records, and the hospital information system. Results: Of the 23 KTRs, 20 were male (86%), 20 patients had fever (86%), and cough and breathlessness were seen in 19 (82%) and 12 (52%), respectively. Acute graft dysfunction was seen in 6 (26%) patients, and the need for renal replacement was seen in 4 (17%) patients. Supplemental oxygen by reservoir mask was utilized in 10 (43%) patients, high-flow nasal cannula in 3 (13%), noninvasive mechanical ventilation in 4 (17%), and invasive mechanical ventilation in 6 (26%) patients. All the KTRs with moderate and severe COVID illness and 6/7 nonsurvivors were infected during the second wave. Overall mortality in this group of patients was very high at 27%, and the mortality in the group on mechanical ventilation was 100%. Conclusions: The second wave of the COVID-19 pandemic was associated with greater severity of illness and high mortality in KTRs.

ABSTRACT

Due to the challenges of the IR 4.0 era and the Covid-19 pandemic at the same time, this paper provides a brief review of the published studies predominantly on biodiesel storage tank materials and followed by the Internet of Things (IoT) system as an alternative monitoring method in biodiesel industries. The suitability of storage material for a longer storage duration due to lower oil demands amidst this pandemic becomes a major concern. In this paper, two important parameters: kinematic viscosity and flashpoint in consideration of storage tank materials relating to surrounding conditions and biofuel blends were discussed. It was found that the degradation of fuel in plastic and glass storage tanks is significant for outdoor storage. Over time, the kinematic viscosity of biodiesel shows an increasing trend meanwhile the flashpoint is in decreasing trend or almost constant. However, these physical properties show very limited changes when stored at an ambient temperature. On another note, IoT systems to date are mostly used to detect fuel theft, fuel consumption, fuel impurities, and fuel tank level but are yet to be used to observe the fuel quality under a longer storage period, more than 6 months. IoT solution with suitable embedded sensors has potential to become the advance solution for remote biodiesel quality monitoring, reducing the need for manpower and interaction. This review paper provides necessary information for further investigations on biodiesel stability, storage material, and monitoring advancement systems. © 2022, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

ABSTRACT

The entire world is now agog with the novel coronavirus disease-2019 (COVID-19) chaos, as it has caused unexpected devastation in almost every country. As the resurgence of the COVID-19 is most certain in the coming two years (most probably during the winter season), extremely stringent methods have to be practiced to lower its spreading. The appropriate measures to be followed by wearing a mask (both infected as well as healthy population), adopting social distancing methods, regular medical checkups, and lowering of the grim emissions of toxins from heavy industries around the world, and other effective methods. This study has presented databases of COVID-19 (as of 25 May 2020), which revealed that most of the western countries are showing decreasing trends after being attained the maximum peak of the ‘Gaussian shape’. In contrast, Asian countries (India, Indonesia, and Pakistan) show, alarmingly, increasing trends that imply great care has to be taken to fight against COVID-19. It is well known that nanomaterials have unique physical and chemical properties (ultra-small size, large surface-area-to-mass ratio, and high reactivity) that are different from bulk materials of the same composition. Therefore, this paper discusses the role of nanomaterials in identifying and offering protection against the virus. Also, it gives an insight into their use in the treatment to treat COVID infected patients. Furthermore, this paper also elaborated the challenges being faced while dealing with coronaviruses with a few feasible solutions to eradicate this untoward danger of the pandemic. A meaningful schematic on ‘flattening of the curve’ is included in this paper by considering several factors into account that may help to lessen or eradicate the present pandemic. © (2020) Society for Biomaterials & Artificial Organs #20042020
