ABSTRACT
Globally, India ranks fourth in oilseed production. About 25 million hectares of land produce 32 million tons of oilseeds, including groundnut, rapeseed, and soybean. The annual per capita demand for edible oil in India is 19.5kg. Domestic production meets only 30% of this demand, and the rest is imported. Of this import, Palm oil has the maximum share (62%) from Indonesia and Malaysia, followed by soya (21%) from Argentina and Brazil, and sunflower oil (16%) from Ukraine and Argentina. Covid-19 pandemic and the ongoing war in Ukraine directly affect the price of edible oil in international and domestic markets. India can potentially increase domestic oilseeds production, thereby reducing the import burden. The Indian government has taken initiatives like the Technology Mission on Oilseeds, palm oil area expansion under Rashtriya Krishi Vikas Yojana, development of buffer stock for oilseeds, and other policies to motivate farmers to use location-specific improved varieties and quality seeds production to fulfill the domestic demands of oilseeds. © 2023 Nova Science Publishers, Inc.

ABSTRACT
Copper (Cu) was one of the first metals to be excavated and used by humans. Copper nanoparticles have a lot of attention due to their high electrical conductivity, high melting point, low electrochemical migration and low cost. It also demonstrated antiviral activity such as a recent study showing that the coronavirus survives for several days on glass, plate, and stain-less steel, but dies within a few hours on Cu. It is observed that controlling particle size expands the range of innumerable applications. Several methods have been employed for the synthesis of Cu nanoparticles such as Physical, Chemical, biological and green synthesis. In the present work, nanoparticles were successfully synthesized by a facile electrochemical deposition method. In which, Copper sulfate pentahydrate (CuSO4.5H2 O), is used as a pre-cursor and Sodium hydroxide (NaOH) used to maintain pH during the deposition in de-ionized water (DI) as a solvent. The structural and optical characterization of nanoparticles were performed by X-ray diffraction (XRD), Field effect Scanning Electron Microscope (FESEM), and UV-Vis Spectroscopy. The FCC structure of Cu nanoparticles has been analyzed by XRD and the size varies from 65 nm-30 nm by controlling pH of electrolyte solution. In the optical studies, it is observed that the bandgap is varying in the range of 2.98 eV to 4.97 eV, calculated by Tauc plot. © 2022. Lokesh et al.
ABSTRACT
Introduction: Mass vaccination is considered one of the most crucial weapons in fighting against the ongoing COVID-19 pandemic. However, the occurrence of breakthrough infections (BTIs) has questioned the vaccine effectiveness of the currently available vaccines. The present study aimed to determine the breakthrough SARS-CoV-2 infections in the vaccinated population and to compare the clinic-epidemiological profile and outcomes between breakthrough cases and unvaccinated SARS-CoV-2 positive cases. Methods: This retrospective case-control study was conducted between April 15, 2021, and June 15, 2021, in a zonal military hospital in Jaipur. We evaluated individuals with BTI as cases which were SARS-CoV-2 positive after 14 days of the second dose of vaccine and unvaccinated SARS-CoV-2-positive individuals as control. The clinical and demographic data was collected from the Indian Council of Medical Research and specimen referral forms were filled out for all persons who had undergone testing for SARS-CoV-2. The outcome of positive cases in terms of discharge and deaths were collected from hospital records. Results: A total of 162 breakthrough COVID 19 infections and 925 unvaccinated positive confirmed controls were recorded within the study duration. The majority of cases presented with mild infection in both case (80.2%) and control groups (72.4%). The risk of hospitalization and occurrence of moderate to severe disease was 2.3 and 4 times more in the non-vaccinated group as compared to the vaccinated group, respectively. No mortality was reported among the breakthrough cases. Interpretation and Conclusions: Despite the occurrence of BTIs, the benefits of vaccines are far greater. Our findings suggest that vaccination is associated with a lower risk of hospital admission, severe disease, and mortality against COVID-19. © 2022 Medical Journal of Dr. D.Y.

ABSTRACT
In this report, we present a pre-organization summary of the fourth workshop on emerging software engineering education (WESEE) held in virtual mode on February 25, 2021, co-located with the 14th Innovations in Software Engineering Conference (ISEC 2021), February 25-27, 2021. The 4th edition of WESEE, a half-day workshop, focuses on open discussions and brainstorming sessions with a theme "Software Engineering Education during COVID-19 Pandemic and Beyond". The workshop consists of two invited talks of 45 minutes each, two hands-on activities, followed by an open-ended concluding discussion session (30 minutes). A total of 70-75 participants including academic faculty members, students, and industry practitioners participated virtually in the workshop. © 2021 Owner/Author.
