 Abstract

: The development of composite concrete beams employing conversional concrete (CC) and lightweight concrete (LWC) is the topic of this research. The typical concrete is made to have an M30 strength. The coarse aggregate of 0%, 20%, 40%, 60%, 80%, and 100% will then be replaced by broken bricks in conventional concrete to create the lightweight concrete for the beam. It was anticipated that the density and strength would decrease as more bricks were added. The amount of air entrainment for the matching density will be examined. Finally, a mix with a reasonable density will be selected to be employed in the composite flexural members together with regular concrete. The main goal is to determine where in a flexural member light weight concrete should be used in addition to conventional concrete. First, during compression, the presumptive position of the light weight and conventional concrete in the cross section of the beam will be studied. The test and cast cubes to determine the cubic strength of various assumed cross sections. Using those findings, the beam will be cast to ensure that the composite material's compression strength is at its highest. It will be tested after curing, and more research on the load to deflection parameter will follow. This enables us to determine whether lightweight concrete may be utilized in beams with traditional concrete.

Abstract: Cryptocurrency is a decentralized digital currency that is based on blockchain technology. Blockchain is a system of technology that records data and information in a way that is very complicated and almost impossible to alter, hack, and deceive the system. A blockchain is a digital ledger of transactions that is duplicated and distributed across the whole network of computer systems on the blockchain, each block in the chain contains several transactions, and every time a new transaction occurs, a record of that transaction is added to every user's ledger. The decentralized database managed by multiple participants is known as Distributed Ledger Technology (DLT). In the current scenario, we are most familiar with Bitcoin, Dogecoin & Ethereum but there are approximately around 5000 different private cryptocurrencies in the world in circulation. Cryptocurrency is a medium of exchange like centralized digital currency but absent of centralization unlike the Indian Rupee, US dollar, British Pound, Euro, etc. In this paper, we are going to understand how cryptocurrencies have evolved, their scopes and future opportunities, and also the regulation of cryptocurrency by the Indian government. We are also going to study in detail, how cryptocurrencies posses a serious threat to the World economy. Studying cryptocurrencies requires a multidisciplinary approach, considering their technical, economic, and social aspects. Cryptocurrencies have introduced a new paradigm for financial transactions and technological innovation. While they offer numerous advantages, they also require careful consideration of risks, regulatory frameworks, and responsible participation. As the cryptocurrency ecosystem continues to mature, it will be essential to monitor developments, adapt to changing regulations, and stay informed to make informed decisions in this dynamic and evolving landscape.

The consumption of industrially processed fruit juices has become increasingly popular in Dhaka City, raising concerns about the implications for public health and legal ethics. This paper aims to examine the various aspects related to industrially processed fruit juices and their effects on public health, as well as the ethical and legal considerations associated with their production and distribution. The study employs a mixed-methods approach, combining a comprehensive literature review with primary data collection. The literature review provides an overview of the fruit juice industry, explores the health implications of consuming industrially processed fruit juices, and examines the existing legal and ethical frameworks. The results reveal potential health risks associated with the consumption of industrially processed fruit juices, including the presence of additives, high sugar content, and inadequate nutritional value. Furthermore, compliance with food safety standards and regulations is found to be inadequate in some cases, raising concerns about consumer protection and public health. The study also highlights the need for consumer education and awareness programs to improve understanding and informed decision-making regarding fruit juice consumption. Additionally, it suggests policy and regulatory interventions to strengthen food safety standards, enhance industry practices, and promote corporate social responsibility.

 Abstract

Agriculture is the backbone of any economy, and with the increasing population, the demand for food is also increasing. To meet the food demand, farmers are using various techniques to increase the yield of the crops. One such technique is to use fertilizers and manure. The traditional method of using fertilizers and manure requires manual intervention, which is not only time-consuming but also labor-intensive. Therefore, we have proposed a solar-powered IoT-based fertigation cum panchagavya (natural manure) dispenser, which will automate the process of transferring fertilizers and manure to the crops.

 Abstract

This report examines the topic of respiratory rate of players while swimming, It is not only about the importance of performance in the start, turn and swimming speed, but also about the design of a strength training program. Different approaches are discussed in the literature, of which two are at the forefront. On the one hand, the optimal intensity of strength training is discussed, and on the other, the question of how to plan a certain strength training. In addition to a running summary of the importance of strength training in swimming, the article shows what physiological adaptations must be achieved to improve performance in the long term. In addition, an attempt is made to explain why some training contents seem to be quite unsuitable from the point of view of increasing strength as a basis for better performance in start, turn and clean swimming. From the above paper, it concludes that

This paper "Ready for Growth: Solutions to Increase Access to Finance and Accounting for Women-owned Business in Visakhapatnam, is designed to shed a light on those barriers. It is the result of a unique partnership with financial assistancefor Businesswomen'sSet-up. Its purpose is to fill a critical gap in our knowledge of what women-owned businesses need in terms of financial products and services. The problems women face in access to finance must be understood in the context of problems in access to finance and accounting for the developing world as a whole. This paper demonstrates that although accessing finance is an integral issue women face when growing their business, it cannot be resolved in isolation of other related impediments. Action to improve women's access must be taken holistically -- along with increased access to training, information. Building on our knowledge of how commercial banks currently reach the women's market, this study can provide banks financial assistances with information to better serve women business owners.

 Abstract

In this paper, we present an effective Wireless technique in which two optimization algorithms i.e., Artificial Bee Colony (ABC) and Grasshopper Optimization algorithm (GOA) has been hybridized. The key motive of the proposed HABCGOA model is to improve the lifespan of the network by reducing its energy consumption. To combat this task, nodes are deployed in the network upon which HABCGOA technique is implemented. In order to select the optimum CH in the network, the proposed model analyses four parameters i.e., node density, residual energy, distance from CH to BS and average distance between two nearby nodes to calculate fitness value. The node with the best fitness value is selected as CH in the network for a particular cluster on iteration. Additionally, we have also introduced the range-based communication in the proposed work by virtue of which non cluster member nodes transfer their data to the nearest CH node instead of transferring it directly to Base Station (BS). The effectiveness or proposed HABCGOA model is analysed and validated by comparing it with similar approaches in MATLAB Software using various dependency factors.

 Abstract

In this research paper, we present a comprehensive analysis of metamaterial unit cells for antenna engineering. The analysis includes the examination of unit cells with both single and double substrates through a waveguide medium. The first unit cell comprises a split ring resonator (SRR) with two splits placed within the perpendicular sides. Inside the SRR, a circular splitted ring resonator (C-SRR) is printed on a copper-backed FR4 dielectric substrate. This configuration exhibits a stop-band phenomenon at 5.5 GHz. The second unit cell also consists of an SRR with two splits within the perpendicular sides. Inside this structure, a circular splitted ring resonator (C-SRR) is designed using two different substrates (FR4 and Rogers RT5880) backed by a metallic ground plane. This unit cell demonstrates a stop-band phenomenon at 10.7 GHz. Furthermore, we conduct a detailed analysis of the extraction of medium parameters such as permittivity and permeability for both metamaterial unit cells. The extraction methodology and results are discussed extensively. To validate our findings, simulations are performed using the CST Microwave Studio, a widely-used commercial software in the field. Through these simulations, we obtain reliable and significant results.

 Abstract

The World Health Organization (WHO) states Substance use as "Harmful or hazardous use of psychoactive substances, including alcohol and illicit drugs". Objectives: Firstly to assess the socio-demographic characteristics and clinical profile of patients attending the drug de-addiction centre. Secondly to determine specific types of psychiatric disorder. Methodology: Study was designed in an exploratory descriptive survey approach. The investigator had selected 115 substance users who are being treated at Delhi's four de-addiction centers. Consecutive sampling was used. The information was gathered through an interview method using a self-structured questionnaire. Results: The drug users were reported to be from a wide range of educational backgrounds and nearly half of the drug users were currently married. The nuclear family accounts for the majority of drug users. Adolescents and young people are at a higher risk of drug misuse. The majority of people were alcoholics. 2/5th of cases were tobacco addicts, while 1/5th were heroin and opium addicts. The maximum of substance user were having pulmonary disorders along with HTN followed by DM. Schizophrenia, BPAD and personal disorder were the common type of psychiatric disorders found. Peptic ulcer disorder, HTN, DM and CAD were found to be significantly associated with age group. Pulmonary disorders and HTN were found to be significant associated with occupation. Conclusion: This study reveals that substance users are falling into a vicious cycle of drug usage at a teenage. To address this significant public health problem of drug use, community-based awareness programmes, and counseling and health camps were essential.
