 Abstract

The aim of this study is to analyze the impact on e-learning among various schools , colleges and universities during covid -19 period . As we all are aware about this pandemic time. All universities , colleges and schools due to this pandemic switched to virtual learning from conventional way of learning . As all schools , colleges and universities are closed all classes are conducted through virtual learning platforms or applications. In this paper a well-structured questionnaire survey method is used to examine the college , school and university student's and faculties teaching-learning experiences during covid-19 period. This questionnaire based survey is being conducted in various schools ,colleges and universities. In this study stratified sampling method is adopted and sample size is two hundred across some schools and colleges of India . This paper present the results of a survey conducted in school ,colleges and university students who were studying from home during covid-19 . What difficulties they are facing while and what benefits they are getting while learning at home . This survey covers the students of age group between 10years and 23 years .The questionnaire consisting of various pros and cons of e-learning during this most critical time

 Abstract

With the help of computer technology, many solutions have been implemented in order for the visually impaired to become accessible and profitable from them. Thinking this was a great idea, we created a desktop application that helps visually impaired people send and read emails like normal people. In this research, the VMAIL system architecture explains about the Python platform. The app uses "text-to-speech" and human speech recognition to make it easy to send, read, and email using a computer. Internet has become so popular where all of the services provided are used effectively by everyone . However, visually impaired people encounter problems in accessing this information as well as using internet services. Advances in computer-based accessibility systems have opened up many opportunities for visually impaired people around the world. Virtual environments based on audio feedback, such as screen readers, have greatly helped visually impaired people access Internet applications. We describe a sound recording design that can be used by visually impaired people for easy and accessible e-mail.

ABSTRACT This research paper explores the theme of the War of Memory and Identity in Yoko Ogawa's The Memory Police (2019), a work of Japanese science fiction. The novel depicts a society where memories and objects gradually disappear, and those who remember them are at risk of being persecuted by the Memory Police. This leads to a struggle between those who seek to preserve their memories and identity, and the forces seeking to erase them. Using the theoretical framework of retrieval failure, this study examines how the characters in the novel suffer from memory loss and the consequences of this loss on their identity and sense of self. The study also analyzes the ways in which the novel reflects the sociopolitical context of Japan, particularly in relation to the loss of memory and identity in the aftermath of World War II. Through the lens of science fiction, the novel explores the complexities of memory and identity, and how they are linked to power and control. This study contributes the understanding of the role of memory and identity in shaping the individuals and societies, as well as the consequences of their loss.

Abstract: Exams are an integral part of a student's academic journey, and the exam period can be a challenging time for many students. The pressure to perform well, combined with the need to study for multiple subjects, can cause students to experience a range of emotions and mental states. This research paper aims to explore the mentality of students during the exam period and identify the factors that can affect their mental health. This research is carried out in the Science and Humanities Department of Yashwantrao Chavan Polytechnic, Ichalkaranji.

 Abstract

Cardio-respiratory fitness is defined as the body's ability in utilizing oxygen to produce energy during physical activity. The best way to measure cardio-respiratory fitness is to assess VO2max. The main aim of this study was to assess cardio-respiratory fitness using Queen's College Step Test and Oxygen Saturation in Undergraduate Female Physiotherapy Students. Queen's step test and oxygen saturation of total 158 physiotherapy students were studied. Data was analyzed using descriptive analysis. Reduced cardio-respiratory fitness in the form of VO2max was identified and they were encouraged for lifestyle modification along with adequate physical activity done regularly to improve their cardio-respiratory fitness.

 Abstract

This study aims to predict stock prices using Long Short-Term Memory (LSTM) neural networks. The LSTM models were trained on historical stock data and used to forecast future prices. The dataset used for training and testing the models was obtained from the Yahoo Finance website, and consisted of daily stock prices of the S&P 500 index. The data was preprocessed and normalized before being fed into the LSTM models. The LSTM models were able to accurately predict the stock prices for the test data, with an average mean squared error (MSE) of less than 0.01. The results demonstrate the effectiveness of LSTM neural networks in predicting stock prices and provide insights for investors and traders to make informed decisions.

 Abstract

Pyrimidones constitute a class of heterocyclic compounds with multifold applications in various fields of chemistry and medicine. The pharmaceutically important scaffold, has been synthesised by different researchers over a century of a work all over the world. Variety of chemical reagents and conditions have been used in this regard but prominently the Lewis acids are normally employed. In the present paper, we would like to report herein the green method for synthesising the dihydropyrimidone derivatives, commencing from the aromatic aldehydes, ethyl acetoacetate and urea under the catalysis of a novel nickel based organometallic reagent without employing any organic solvent for the conduct of a reaction . The work up is easy and the product formation takes place in very high yield. The products are characterised by IR and 1 H NMR spectroscopic spectral data.

 Abstract

In recent years, the environmental effects concerns of the traditional car (ICE-Internal Combustion Engine) have led to the enhancement and growth of the electric vehicle (EV). The evolution of the regenerative braking system leads to increase overall vehicle performance (RBS) whenever driver applies the brake the energy which is completely lost in the form of kinetic energy due to friction loss between wheel of vehicle and road must be used and recycled, increasing the vehicle's efficiency. The reputed car companies such as BMW, Toyota, Lexus, Mercedes Benz, Land Rover, Volkswagen and General Motors have been using this technique for their EV's. This paper explores the applicability of the regenerative braking system and its applicability in various sectors to solve the existing problems
