ABSTRACT

Social activities, economic benefits, and environmental friendly approach are very much essential for a sustainable production system. This is widely observed during the Covid-19 pandemic situation. The demand for essential goods in the business sector is always changing due to different unavoidable situations. The proposed study introduces a variable demand for controlling the fluctuating demand. However, a reworking of produced imperfect products makes the production model more profitable. Partial outsourcing of the good quality products has made the production system more popular and profitable. Separate holding cost for the reworked and produced products are very helpful idea for the proposed model. Moreover, consumption of energy during various purpose are considered. Separate green investment make the model more sustainable and eco-friendly. The main focus of the model is to find the maximum profit through considering optimum value of lot size quantity, average selling price, and green investment. The classical optimization technique is utilized here for optimizing the solution theoretically. The use of concave 3D graphs, different examples, and sensitivity analyses are considered here. Furthermore, managerial insights from this study can be used for industry improvement. © 2022 the Author(s), licensee AIMS Press.

ABSTRACT

This study aims to analyze the dynamics of the published articles and preprints of Covid-19 related literature from different scientific databases and sharing platforms. The PubMed, ScienceDirect, and ResearchGate (RG) databases were under consideration in this study over a specific time. Analyses were carried out on the number of publications as (a) function of time (day), (b) journals and (c) authors. Doubling time of the number of publications was analyzed for PubMed "all articles" and ScienceDirect published articles. Analyzed databases were (1A) PubMed (01/12/2019-12/06/2020) "all_articles" (16) PubMed Review articles) and (1C) PubMed Clinical Trials (2) ScienceDirect all publications (01/12/2019- 25/05/2020) (3) RG (Article, Pre Print, Technical Report) (15/04/2020 - 30/4/2020). Total publications in the observation period for PubMed, ScienceDirect, and RG were 23000, 5898 and 5393 respectively. The average number of publications/day for PubMed, ScienceDirect and RG were 70.0 +/- 128.6, 77.6 +/- 125.3 and 255.6 +/- 205.8 respectively. PubMed shows an avalanche in the number of publications around May 10, the number of publications jumped from 6.0 +/- 8.4/day to 282.5 +/- 110.3/ day. The average doubling time for PubMed, ScienceDirect, and RG was 10.3 +/- 4 days, 20.6 days, and 2.3 +/- 2.0 days respectively. The average number of publications per author for PubMed, ScienceDirect, and RG was 1.2 +/- 1.4, 1.3 +/- 0.9, and 1.1 +/- 0.4 respectively. Subgroup analysis, PubMed review articles mean review <0 vertical bar 17 +/- 17 vertical bar 77> days: and reducing at a rate of -0.21 days (count)/day. The number of publications related to the COVID-19 until now is huge and growing very fast with time. It is essential to rationalize and limit the publications.

ABSTRACT

Background The recent pandemic of coronavirus disease 19 (COVID-19) has been causing intense stress among the global population. In the case of hospitalized and ICU-admitted COVID-19 patients with comorbidities, it has been observed that a major portion of them are diabetic. Therefore, researchers had indicated a link between diabetes mellitus (DM) and COVID-19. Furthermore, DM is a potential risk factor for the severity of COVID-19 cases. Thus, in this study, the correlation existing between diabetic patients and COVID-19 was summarized. Main body of the Diabetic patients have a weaker immune system, less viral clearance rate, malfunctions of metabolic activity due to their high blood glucose level, and other associated problems. This does not increase the susceptibility for the patients to be infected with COVID-19. However, the severity of COVID-19 can worsen due to the comorbidity of DM. Short conclusion Proper management, appropriate use of drugs that do not increase the ACE2 expression, lowering blood glucose level, decreasing the susceptibility of SARS-CoV-2, and maintaining a healthy lifestyle could be effective.

ABSTRACT

Amidst the current pandemic situation which has been going on for a significant period of time now, although vast numbers of people are safe in their homes, this crisis has rendered millions of people unemployed, mainly the daily wage labourers, etc., who are now struggling with not only the gravity of the coronavirus but also with hunger and unemployment. We are witnessing a rich and poor divide that has crossed boundaries that were never explored before. We are all aware of the hardships of the people who are daily struggling just to manage a day’s food for their family, and so as responsible engineers, we plan to develop an Android application which aims on directing financial aid to those who are actually needy by gathering funds from millions of donors across the nation who share the same ideology and wish to help these people out but are unable due to the pandemic related restrictions. People who are deserving of this financial aid and also the people who wish to donate will be able to register themselves on the application, post which verification will be conducted for both the parties after which a designated amount of money will transferred to the needful directly. All cyber security protocols are aimed to be implemented so as there is no presence of any anomaly. © 2022, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

ABSTRACT

In this work, we have described the analysis of digitized sequences of genetic information by means of the notions of entropy. The occurrence of a particular pattern in the genetic sequence is paid special attention. The occurrence of genetic word is expressed in a density manner. The occurrence frequency of the q-gram genetic word of interest is determined with the help of finite impulse response (FIR) type filter along the sequence. It is in turn, used for the determination of horizontal correlations, i.e., correlations between the word along the sequence. We use the probability distribution of the genetic word occurrence as the input for the calculation of entropy in the sequence. The sequence entropy is further used for principal component analysis (PCA) to determine the similarity/dissimilarity between the biological sequences. We have considered seven human corona virus sequences. Entropy-based similarity study for SARS-CoV-2 strains is presented in this paper. © 2021, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

ABSTRACT

Purpose: Presently, Indian sectors are manifesting a higher level of interdependency and making the economy more vulnerable to human-caused and natural disasters. COVID-19 pandemic creates a devastating effect on the world economy. The Indian economy was expected to lose around ₹ 32,000 crores every day during the first 21 days of complete lockdown. This motivates to conduct the research on how the COVID-19 pandemic affects the port logistics sector and how the effects of COVID-19 on port logistics propagate to other sectors owing to its interconnectedness and affect the economy of the country. Design/methodology/approach: The purpose of the study is analyze how perturbation in one sector can affect the system of interdependent sectors and it is done with interdependency analysis. It uses Wassily Leontief’s inoperability input-output model (IIM) and interval programming (IP) to develop a framework. IP is used to address situations where assumptions are not valid because of uncertainties associated with disruptive events. Findings: The model helps in describing how the effect of the COVID-19 pandemic in port logistics can propagate owing to the interconnectedness across other sectors. The model uses the latest five-year data available on the Organisation for Economic Co-operation and Development database. It uses metrics like inoperability and economic loss to study the consequences of COVID-19 pandemic on various sectors. This study also presents the ranking of the affected sectors based on their inoperability and economic loss Research limitations/implications: In the future study, other techniques like dynamic evolution, multiplex network analysis, analytical hierarchy process, pinch analysis, stochastic evolution and pinch graph could be integrated with input-output (I-O) modelling. Integrated stochastic evolution with an I-O model allows capturing the likelihood of the events;it includes probability distributions instead of point estimates for scenario parameters. Methods like dynamic evolution and multiplex network analysis can be introduced in future work to shed lights on interdependency among the sector, which could potentially provide additional insights for transport policy formulations. Originality/value: This study discusses the theory, methodology and application of the IIM-IP model in the domain of port logistics. The developed IIM-IP model helps decision-makers to manage risk in port logistics. Firstly, it studies how different sectors are interconnected with each other. Secondly, it helps in identifying the most vulnerable sectors based on economic loss and inoperability. Thirdly, it provides the ranking of the sectors based on their economic losses. © 2021, Emerald Publishing Limited.

ABSTRACT

Technology has played an integral role in the field of education. Its prominence and efficacy have proved to be a great boon for the people in this New Normal after the severe outbreak of COVID-19. Although the entire world is confined among the four walls, it is the technology that contributed a lot by enabling the conduction of online classes through different Learning Management Systems and multidimensional efforts of student-teacher fraternity. Earlier the Distance Learning was prevalent but was not given much importance owing to own limitations. This period of emergency has identified and highlighted the need and immense contribution of technology in digital pedagogy through online mode. In this paper we have surveyed various ways, where technology has played a gigantic role in the field of education. Various techniques for monitoring the attendance of the learners are also explored. Identifying several problems and related drawbacks of the digital transformation in the pedagogical approach, we have proposed some dynamic systems that can resolve certain issues efficiently and effectively. Solutions to mitigate the problems of attendance and to prevent the lack of attention/concentration of the students during the conduction of the online classes are presented. © 2021 Institute of Physics Publishing.

ABSTRACT

Background: Coronavirus disease 2019 was first identified in Wuhan, the capital of China's Hubei province, in December 2019. India has witnessed a massive surge of coronavirus cases. Main text: This study details the measures to be taken by the clinicians involved in doing otorhinolaryngology and head neck surgery in light of the recent coronavirus disease 2019 pandemic. All COVID-positive patients should be admitted in a separate COVID ward, and patients should be screened for COVID-19 before admission. Only emergent ENT surgeries should be done in an operating room having a negative pressure environment with high-frequency air changes, and all staff must wear personal protective equipment. The anesthetist intubates the patient while the surgical team waits outside the operation theater post-intubation for 21 min. For otology surgery, double draping of the microscope should be done;for rhinology surgery, concept of negative-pressure otolaryngology viral isolation drape (NOVID) system should be used. Smoke evacuation system is set up inside the tent to evacuate any smoke produced during the surgery. Tracheostomy should be done at least after 10 days of mechanical ventilation with cuffed, non-fenestrated tracheal tube inserted through the tracheal window, and a separate closed suction system is used for suctioning. After the surgery is completed, disposal of PPE kit needs to be done according to local guidelines. After completion of the surgery, the full anesthesia unit should be disinfected for 2 h with 12 % hydrogen peroxide. Chlorine-containing disinfectant (2000 mg/L) is used to clean the floor of the operation theater and clean all the reusable medical equipment. Ultra-low volume 20 to 30 mL/m of 3% hydrogen peroxide is used to fumigate the OT for 2 h. Conclusions: COVID-19 is a newly discovered infectious disease. Measures need to be taken to prevent transmission and attain a plateau and decline in the disease. Otorhinolaryngologists and head neck surgeons are at high risk of this infection. This review summarizes the protocol for otorhinolaryngologists and head neck surgeons caring for patients in this current scenario. Protocols need to be strictly followed to prevent the spread of this disease.
