Countries’ Vulnerability to COVID-19 Depending on the Health Behaviour Patterns of the Population
Authors: Letunovska Nataliia , Boliukh Viktoriia
Published: April 2023

The article analyses the factors determining the level of vulnerability of regions to the influence of pandemic threats. Statistical indicators for 2021-2022 regarding the course of the COVID-19 pandemic in Ukraine were taken for analysis, namely the number of infected persons and the number of deaths per thousand of the population. Indicators in the field of healthy behaviour of the population were adopted as variable determinants (namely, the amount of healthy food consumption, sugar consumption, the number of people engaged in physical culture and sports, the number of smoking people and the proportion of obese people), for which a quantitative statistical base is available exhaustively for all 24 regions of the country. The study aims to confirm or refute the hypothesis regarding the existence of a connection between the regional behavioural patterns of the population in the health field and the region’s vulnerability to the impact of the COVID-19 pandemic. For the analysis, discriminant and canonical analyses were used, which were carried out in the STATISTICA software environment. Empirical indicators made it possible to confirm the hypothesis regarding a connection between regional behavioural patterns and the region’s level in terms of the number of deaths from COVID-19. The hypothesis about a possible dependence between behavioural patterns and the number of infected with COVID-19 was not confirmed – the discrimination model was statistically insignificant. This suggests that establishing dependencies requires more input parameters to describe the model. It was determined that the consumption of healthy foods (milk, berries, fish) influences the mortality rate from COVID-19 (high, medium or low). Also, indicators with a high degree of influence include the number of people engaged in physical culture and sports, and the proportion of people with obesity. The results of the study will be useful in the development of regional and national strategies to promote the formation of the resilience of territories to pandemic threats and in the selection of tools for working with the population within the framework of informational and educational campaigns for prevention of severe courses of diseases caused by epidemic factors.
Advanced Turf-type Bermudagrass Experimental Genotypes Show Marked Variation in Drought Response

Published: April 2023

Bermudagrass (Cynodon sp.) is one of the most commonly used warm-season turfgrasses in the southern areas and transition zone of the United States. Due to the increasing demand for water resources and periodic drought, it is important to improve the drought resistance of bermudagrass for water savings and persistence under drought stress. This study was conducted to determine whether experimental bermudagrass genotypes have improved drought resistance compared with the standard cultivars Tifway and Riley’s Super Sport (Celebration®) at Stillwater, OK. The trials were designed as randomized complete blocks with four replications in Expt. I and three replications in Expt. II. In each experiment, genotypes were subjected to progressive acute drought conditions using polyethylene waterproof tarps to exclude precipitation over a period of at least 72 d. Bermudagrass entries were evaluated for turfgrass quality, leaf firing, normalized difference vegetation index, and live green cover at least once each week during the dry-down. Substantial drought response variations were found in this study, and all parameters were positively and highly correlated. A turf performance index (TPI) was assembled based on the number of times an entry ranked in the top statistical group across all testing parameters on each date. ‘DT-1’ (TifTuf®) and OSU1221 had the top TPI in both experiments. Most of bermudagrass experimental genotypes had equal or greater TPI than the standard Tifway, showing improved drought resistance through breeding effects. The identification of superior drought resistance experimental genotypes provided useful information to breeders on cultivar release.
Simulating thermal density operators with cluster expansions and tensor networks
Authors: Vanhecke Bram , Devoogdt David , Verstraete Frank , Vanderstraeten Laurens
Published: April 2023

We provide an efficient approximation for the exponential of a local operator in quantum spin systems using tensor-network representations of a cluster expansion. We benchmark this cluster tensor network operator (cluster TNO) for one-dimensional systems, and show that the approximation works well for large real- or imaginary-time steps. We use this formalism for representing the thermal density operator of a two-dimensional quantum spin system at a certain temperature as a single cluster TNO, which we can then contract by standard contraction methods for two-dimensional tensor networks. We apply this approach to the thermal phase transition of the transverse-field Ising model on the square lattice, and we find through a scaling analysis that the cluster-TNO approximation gives rise to a continuous phase transition in the correct universality class; by increasing the order of the cluster expansion we find good values of the critical point up to surprisingly low temperatures.
Juventudes, precariedade e ética da coabitação: Implicações educacionais dos modos de alocação diferencial da precariedade
Authors: Scherer Renata Porcher , Da Silva Roberto Rafael Dias
Published: April 2023

O artigo versa sobre os modos pelos quais as juventudes contemporâneas, no Brasil, têm sido enquadradas por um amplo e diversificado conjunto de discursos midiáticos acerca de sua constituição subjetiva. Ora enredados pelas potencialidades de ser um Millenial e desfrutar de uma ambiência social diferenciada, ora interpelados pela construção de uma leitura da condição juvenil marcada pela falta, como é o caso dos “nem-nem-nem”, conseguiu-se diagnosticar determinados modos de alocação diferencial da precariedade na constituição destas figuras subjetivas. Este cenário é intensificado no contexto da pandemia causada pelo coronavírus. Sob inspiração dos escritos políticos de Judith Butler, aponta-se para o advento de pautas que parecem extrapolar as questões identitárias e deslocam-se para uma luta e organização coletiva em favor de uma política da singularidade. Objetivamente, será atribuída uma centralidade analítica, tanto para as implicações educacionais desta alocação diferencial da precariedade e aos diferentes enquadramentos políticos e normativos desta questão, quanto para as possibilidades de as juventudes criarem novas alianças a partir da precariedade, em favor de uma ética da coabitação.

Existe poca información sobre los efectos de las fechas de siembra y los genotipos sobre la infestación de saltamontes (Zonocerus variegatus L.) y la acumulación de materia seca en el órgano radicular de la yuca. Se realizó un experimento en el sitio experimental de la Escuela de Agricultura y Ciencias de la Alimentación, de la Universidad de Njala durante las temporadas de cultivo 2007/2008 y 2015/2016. Este estudio evaluó los efectos de la fecha de siembra y los genotipos de yuca sobre la infestación de saltamontes y la acumulación de materia seca en la raíz de la yuca. El experimento utilizó cuatro genotipos de mandioca (Cacao, SLICASS 1, SLICASS 4 y SLICASS 6) y tres fechas de siembra (junio, septiembre y diciembre) dispuestos en un diseño de bloques completos aleatorizados (RCBD) con tres repeticiones. Los resultados mostraron que la incidencia y la gravedad de los ataques de saltamontes, así como el contenido de materia seca radicular, fueron significativamente diferentes (p<0.05) entre la variedad y las fechas de plantación. Las puntuaciones de severidad del saltamontes aumentaron 3 meses después de la plantación (MAP) (1.6) a 9 MAP (2.6). Del mismo modo, la incidencia aumentó de 3 MAP (23 %) a 9 MAP (29.7 %). El porcentaje más bajo de incidencia de saltamontes se observó en junio (24.8 %), seguido de septiembre (26 %), mientras que diciembre registró el más alto (30.7 %). Se observaron tendencias similares para la puntuación de severidad en las fechas de plantación de junio (1.5), septiembre (2.2) y diciembre (2.5). El genotipo SLICASS 6 (42.21 %) tuvo el mayor contenido de materia seca radicular, seguido de SLICASS 1 (42.17 %), mientras que Cacao y SLICASS 4 tuvieron el más bajo de 41.90 %. Las parcelas protegidas registraron un mayor contenido de materia seca radicular (44 %) que las parcelas no protegidas (40.9 %). La identificación de la variedad de yuca tolerante, la protección del campo de yuca contra la infestación de saltamontes y la cosecha de yuca en diciembre podrían aprovecharse para la selección y producción de la variedad de yuca tolerante con rasgos de procesamiento deseados, tales como un alto contenido de materia seca de la raíz.

The aim of this study was to examine the effect of isotonic drinks on students’ heart rates. This experimental research relied on a randomized pretest–posttest control group design; it consisted of one control group (t1) and one treatment group (t2). All participants were treated with the same exercise protocol including endurance training specifically for the branches of pencak silat (exercise straight kick techniques, scythe while hitting). The control group consumed mineral water, while the treatment group was provided with an isotonic drink after exercise. Following the treatment phase was the calculation of participants’ heart rates for one minute; this process was replicated three times: before the exercise (T1), 60 to 90 minutes after the exercises (T2), and 10 minutes after the exercise interval (T3). All data were analyzed using a T-test. The results revealed that the initial heart rates of the control and treatment groups were 72.6 ± 10.36 and 66.3 ± 8.60, respectively.  In other words, there were no differences between the two groups. The initial heart rates of the control group control and treatment group after the exercise was 159.2 ± 10.48 and 149.0 ± 8.59, respectively. According to the t-test results, there was a difference (p 0.05) in the heart rates of the control group and treatment group after the exercises. The initial heart rates of the control group control and treatment group after the exercise interval was 76.2 ± 11.0 and 65.9 ± 8.62, respectively.

Published: April 2023

The purpose of this study was to find out other benefits of scuba diving for persons with physical disabilities through a systematic literature review. The technique used in this research is a literature study. The literature analysis used the Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) method. A total of seven articles were selected for review. A review of articles shows that diving can be treated as a multidimensional therapy in water, allowing people with and without disabilities to share activities together. Such rehabilitation involves comprehensive stimulation of the human body through social interaction through participation in class, influencing the mental and physical environment to regain awareness of one's own body and the movements one can perform, to feel one's own body position and the possibility of providing direction of motion and the benefits of increasing self-reliance in water. Utilization the aquatic environment allows muscle relaxation, which, as a result, can have a positive effect on spasticity and often increase the very limited range of motion of joints in a natural environment allowing increased movement and coordination in a much easier manner than in a terrestrial environment. A person who scuba dives could learn and demonstrate independence by keeping himself safe, as well as the safety of his colleagues. Diving encourages a person to spend time with other people and, as such, provides an opportunity to be in a group whose members include people without disabilities, as well as people with locomotor system dysfunction, providing a sense of affiliation with the group and responsibility for it. members and create a positive mental state.
N2O Emission Pattern in A Legume-Based Agroecosystem
Authors: Nicolardot Bernard , Guinet Mae , Voisin Anne Sophie , Hénault Catherine
Published: April 2023

Legumes provide several ecological services to agroecosystems, but there is a lack of references on services related to N flows for a wide range of legume crops. N2O emissions were measured in two field experiments using a two-year legume-cereal crop sequence. In the first year (2014 and 2016), different legume crops were grown (lupin, pea, fava bean, common bean, soybean, chickpea) and compared to fertilized cereals (barley and sorghum). Once the seeds were harvested and the residues incorporated in the soil, unfertilized wheat was sown and harvested in the second year (2015 and 2017). N2O emissions, as well as soil temperature and moisture, were measured continuously using an automated chamber method during the two years of each experiment. Daily N2O emissions were less than 10 g N-N2O ha-1 d-1, with higher values (ranging from 10 to 90 g N-N2O ha-1 d-1) being measured during exceptionally rainy conditions. Daily N2O emissions were mainly influenced by climatic conditions for field experiments and far less by inorganic N content, except for N-fertilized cereals. For both field experiments, cumulative N2O emissions during legume and cereal pre-crops + fallow period between pre-crop harvest and wheat sowing (1st year) (mean values 365.4 and 318.1 g N-N2O ha-1 for experiment I and II, respectively) were higher than during wheat crop cultivation (2nd year) (155.8 and 101.5 g N-N2O ha-1 for experiment I and II, respectively). For field experiment II, N2O emissions were slightly higher for the N fertilized cereal pre-crops (529.8 and 523.3 g N-N2O ha-1 for barley and sorghum, respectively) compared to legume pre-crops (mean values 380.6 and 417.2 g N-N2O ha-1 for legumes sown in March and May, respectively), while no significant difference was measured for field experiment I. There was no difference in N2O emissions during the cultivation of the different legume species. Furthermore, when wheat was grown after legumes or N fertilized cereals, N2O emissions were comparable for the different experimental treatments with no relation established with the amounts of N present in crop residues or their C: N ratios. Despite the small differences in emissions between N-fertilized cereals and grain legumes, introducing these leguminous species in crop rotation and in these pedoclimatic conditions makes it possible to substitute synthetic N fertilizer and mitigate the greenhouse gases emitted from these cropping systems. However, further research is still needed to clarify and quantify the value of legumes in mitigating and reducing greenhouse gas emissions from cropping systems.

Authors: Ghosh Arka , Cherian Rithwik J , Wagle Surbhit , Sharma Parth , Kannan Karthikeyan R , Bajpai Alok , Gupta Nitin
Published: April 2023

Background

Globally, most individuals who are susceptible to depression do not receive adequate or timely treatment. Unguided computerized cognitive behavioral therapy (cCBT) has the potential to bridge this treatment gap. However, the real-world effectiveness of unguided cCBT interventions, particularly in low- and middle-income countries (LMICs), remains inconclusive.

Objective

In this study, we aimed to report the design and development of a new unguided cCBT–based multicomponent intervention, TreadWill, and its pragmatic evaluation. TreadWill was designed to be fully automated, engaging, easy to use, and accessible to LMICs.

Methods

To evaluate the effectiveness of TreadWill and the engagement level, we performed a double-blind, fully remote, and randomized controlled trial with 598 participants in India and analyzed the data using a completer’s analysis.

Results

The users who completed at least half of the modules in TreadWill showed significant reduction in depression-related (P=.04) and anxiety-related (P=.02) symptoms compared with the waitlist control. Compared with a plain-text version with the same therapeutic content, the full-featured version of TreadWill showed significantly higher engagement (P=.01).

Conclusions

Our study provides a new resource and evidence for the use of unguided cCBT as a scalable intervention in LMICs.

Implementation Cascade of a Social Network–Based HIV Self-testing Approach for Men Who Have Sex With Men: Cross-sectional Study
Authors: Kwan Tsz Ho , Chan Denise Pui Chung , Wong Samuel Yeung-shan , Lee Shui Shan
Published: April 2023

Background

HIV testing is the cornerstone of strategies for achieving the fast-track target to end the AIDS epidemic by 2030. Self-testing has been proven to be an effective health intervention for men who have sex with men (MSM). While social network–based approaches for distributing HIV self-tests are recommended by the World Health Organization, their implementation consists of multiple steps that need to be properly evaluated.

Objective

This study aimed to assess the implementation cascade of a social network–based HIV self-test approach for reaching MSM who had never undergone testing in Hong Kong.

Methods

This is a cross-sectional study. Seed MSM participants were recruited through different web-based channels, who in turn invited their peers to participate in this study. A web-based platform was set up to support the recruitment and referral process. Participants could request for an oral fluid or a finger-prick HIV self-test, with or without real-time support, after completing a self-administered questionnaire. Referrals could be made upon uploading the test result and passing the web-based training. Characteristics of participants completing each of these steps and their preferences for the type of HIV self-test were evaluated.

Results

A total of 463 MSM were recruited, including 150 seeds. Participants recruited by seeds were less likely to have previously been tested for HIV (odds ratio [OR] 1.80, 95% CI 1.06-3.04, P=.03) and have lower confidence in performing self-tests (OR 0.66, 95% CI 0.45-0.99, P=.045). Almost all (434/442, 98%) MSM who completed the questionnaire requested a self-test, of whom 82% (354/434) had uploaded their test results. Participants requesting support were new to self-testing (OR 3.65, 95% CI 2.10-6.35, P<.001) and less confident in carrying out the self-test correctly (OR 0.35, 95% CI 0.22-0.56, P<.001). More than half (216/354, 61%) of the eligible participants initiated the referral process by attempting the web-based training with a passing rate of 93% (200/216). They were more likely to have sought sex partners (OR 2.20, 95% CI 1.14-4.25, P=.02), especially through location-based networking apps (OR 2.13, 95% CI 1.31-3.49, P=.002). They also gave higher usability scores along the implementation cascade (median 81 vs 75, P=.003).

Conclusions

The social network approach was effective in diffusing HIV self-tests in the MSM community and reaching nontesters. Support and option to choose a preferable type of self-test are essential to address users’ individual needs when delivering HIV self-tests. A positive user experience throughout the processes along the implementation cascade is vital to transform a tester into a promoter.

Authors: Lang Zihan , Huang Run , Zhang Zhen
Published: April 2023

On Amazon’s cross-border e-commerce platform, tea products are iconic commodities that account for a relatively large amount of exports between China and the US, and play an important role in the foreign trade market, while the e-commerce development of tea enterprises is also of great significance to the construction of the national agricultural economy. This paper mainly takes the product promotion information of 20 Chinese and US tea enterprises on the Amazon platform as an example, and uses multimodal discourse analysis theory and Maslow’s hierarchy of needs to conduct a comprehensive analysis of the three promotion forms of text, pictures and videos. With the support of the above two theories, the paper aims to interpret the characteristics of the consumer touch points image expressed in the product promotion messages of Chinese and US tea enterprises, so as to provide reference for cross-border tea enterprises in the field of e-commerce marketing and international competition.

Published: April 2023

Film and television works refer to audio files with or without words and video files that can be recorded, which also enjoy copyright. In this era of short video fast food, movies and TV series have become the benchmark in the cultural field with their mature scripts, careful shooting and large investment of funds and personnel. The copyright protection of movies and TV series is the foundation for the long-term development of China’s film and television industry, and has a great impact on the development of China’s cultural industry. With film and television dramas becoming increasingly popular subjects for short-form video creation on the Internet, short-form video users and film and television drama creators have formed a fierce collision of rights. However, in practice, the copyright protection of film and television series is faced with such problems as high creation costs and low transport costs, high difficulty and high cost for platforms to identify infringing videos, and no clear standards for judicial identification of infringement issues. Therefore, based on the concept of the haven principle and the principle of proportion, this paper uses the method of empirical research to analyze the current situation of film and television play copyright protection in our country by combining the Copyright Law and the short video infringement case of the popular the film “Nagatsuko”. Specifically, this includes legislation to clarify the limits and scope of judicial determination, refine the legal responsibilities of the three main parties, establish a legal risk prevention and control mechanism, and establish a benefit sharing mechanism between creators and short video users, thus promoting coordinated coexistence and win-win cooperation between users of short online videos and creators of TV dramas.

One of the final processed products from coconut that is popular in Indonesia, even in several other countries, for the last 3 years is Virgin Coconut Oil (VCO), which is processed directly from coconut meat. Processing of these products is part of the application of Applied Technology in the development of Coconut commodity products, and is very affordable in terms of production costs for the people in Belu district, NTT province, which has a land border between the Republic of Indonesia and Timor Leste, where the people does not well know about VCO processing technology accordance with quality standards. This study aims to analyze rancidity of VCO produced by gradual heating method on the effect of fermentation time by determining parameters of water content, peroxide value, and free fatty acid content based on the applicable Indonesian National Standard (SNI). Each parameter has been fermented for 2 hours, 6 hours and 10 hours as a treatment in this observation and analyzed in a descriptive way through the results chart. The results showed that the treatment for 2 hours, 6 hours and 10 hours had a moisture content of 0,15%; 0,12%; 0,1% then free fatty acid content is 0,09%; 0,10%; 0,11% and also peroxide value 0,52 mg ek/kg respectively. Based on the results of this study, it can be concluded that each test result is still below the threshold value according to the provisions of the Indonesian National Standard (SNI) 7381:2008.

Published: April 2023

Threats to food security for the Indonesian nation as an agricultural country are still occurring where the government is still opening import faucets, especially for food products. For this reason, Indonesia needs to build food self-sufficiency by optimizing its potential and resources, one of which is through the use of post-harvest technology. Utilization of post-harvest technology can be carried out on all types of commodities, one of which is coconut. Coconut as a leading commodity in the agricultural sector is a multifunctional plant and can grow in all regions of Indonesia. Even though there are a lot of coconut products in all regions of Indonesia, especially in the regions, the availability of technology to improve the quality of post-harvest production is still low. Therefore this study aims to design a coconut peeler machine. The results of the research are in the form of a portable coconut peeler with a servo motor that can be applied in rural areas to be used by farmers to increase the productivity of post-harvest coconut management. The development of this research has several updates, namely a type of portable tool that is easy to carry anywhere

Published: April 2023

O fósforo das águas residuárias é um importante macronutriente, e sua descarga em grandes quantidades pode favorecer a eutrofização de lagos e córregos. Assim, tratamentos específicos podem ser utilizados para sua remoção em efluentes. O uso de coagulação e floculação para remoção de fósforo tem sido amplamente utilizado devido a sua flexibilidade e alta eficiência, e, para isso, existem diversos produtos disponíveis. Sendo assim, o objetivo do presente estudo foi avaliar a eficiência do uso de sulfato de alumínio, cloreto de polialumínio (PAC), cloreto férrico e coagulantes taninos na remoção de fósforo de efluentes domésticos e industriais, utilizando dados disponíveis em trabalhos da literatura. Quando foram utilizados cloreto férrico e sulfato de alumínio, a mediana foi de aproximadamente 90% e o PAC foi de 80%. O uso de tanino resultou em maior variação nos valores de eficiência e menor remoção de fósforo (<75%). A dosagem média de coagulante (mg coagulante.(mg TP inicial)-1) foi de 9.33 mg.mg-1 para o PAC; 8.09 mg.mg-1 e 7.96 mg.mg-1 para cloreto férrico e sulfato de alumínio, respectivamente.
IMPACTO DA RECIRCULAÇÃO DE LIXIVIADO NA PRODUÇÃO E QUALIDADE DO BIOGÁS GERADO EM ATERROS SANITÁRIOS: REVISÃO SISTEMÁTICA
Authors: Andrade Fernanda Nascimento de , Pereira van Elk Ana Ghislane Henriques
Published: April 2023

O biogás e o lixiviado, gerados a partir da decomposição dos resíduos sólidos urbanos (RSU) em aterros sanitários, podem causar grandes impactos ambientais quando não coletados e tratados adequadamente. A recirculação de lixiviado (RL) é uma técnica que vem dentre outros fatores, sendo usada como um meio de reduzir os custos atrelados ao transporte e tratamento do lixiviado, assim como, de contribuir para uma mais rápida estabilização da fração orgânica dos RSU. Fato que pode impactar num aumento da produção do biogás em um tempo menor. Desta forma, este trabalho teve como objetivo avaliar a influência da RL na produção e qualidade do biogás gerado em aterros sanitários por meio de uma revisão sistemática de pesquisas realizadas na última década, para assim, construir uma síntese atualizada dos principais resultados obtidos em laboratório e em larga escala. Os resultados encontrados mostraram que o acúmulo de compostos tóxicos é um dos principais problemas observados com a prática da RL. O uso de aditivos, do controle da taxa e frequência da recirculação e da suplementação de calor ao lixiviado recirculado, foram algumas das técnicas observadas que vem sendo investigadas como meio de aprimorar a influência da recirculação no processo de biodegradação dos resíduos e aumento da produção de biogás. Os resultados encontrados evidenciaram que a RL impactou de diferentes formas a produção e qualidade do biogás gerado através da decomposição dos resíduos, mostrando-se eficaz em algumas pesquisas para o aumento da produção e qualidade do biogás, assim como, ineficaz em outras pesquisas.

Abstract: The intelligent packaging solution aims to use an electronic packaging solution to combat the problem of opening packages during transportation as well as to measure the characteristics of the product , the inner and outer atmosphere of the package . The project IPS aims to use electronic packaging solutions to effectively trigger an alert when a package is opened . This is done by using many sensors in a fail-safe system. The problem with single sensor-based systems is that they do not correlate data from different means . IPS uses many sensors that continuously track the physical parameters inside the packages to ascertain if the package has opened or there has been some rise in temperature (for pharmaceutical and temperature – sensitive products). Once this alert has been sent to those concerned, they can take necessary action

Abstract: The global road safety annual report estimates that 1.24 million individuals worldwide pass away every year in trafficrelated incidents. In addition to the death toll listed above, about 50 million people suffer catastrophic injuries that have a lasting impact on their lives. The proposed system will take in the distance measured by the ultrasonic sensors as an input and vary the speed of the vehicle accordingly which will slow down the vehicle and prevent a collision. We also have the implementation of Automatic-headlights which further reduces the chances of human error by automatically turning on the headlights. We are also adding a luxury component by providing automatic seat adjustment to the driver. In this driver seat will be automatically adjusted based on the preference of the driver.

Abstract: Today’s tall buildings are becoming more and more slender, leading to the possibility of more sway in comparison with earlier high-rise buildings. improving the structural systems of tall buildings can control their dynamic response. With more appropriate structural forms such as shear walls and tube structures and improved material properties. The general design concept of the contemporary bearing wall building system depends upon the combined structural action of the floor and roof systems with the walls. The floor system carries vertical loads and, acting as a diaphragm, lateral loads to the walls for transfer to the foundation. Lateral forces of wind and earthquake are usually resisted by shear walls which are parallel to the direction of lateral load. These shear walls, by their shearing resistance and resistance to overturning, transfer the lateral loads to the foundation. In the present study a 45 storey high rise building, with podium up to 4th floor level is considered. After podium level (4th floor level), there is no sudden change in plan because if there is any sudden change it may result in the stiffness/torsional irregularities of building if a small seismic forces or any other less magnitude horizontal force strike the structure. The optimization techniques which are used in this project are firstly considered the size of shear wall is same throughout the building and then analysis is done from the result the failed shear wall dimensions are increased to resist the whole structure, in this way the optimization was done for number of time till the whole structure comes to stable to resist the forces. In this present project shear wall design and optimization is done by using the software Etabs and the shear walls are arranged in such a way to resist the lateral forces in zone III region throughout the structure according to Indian codes.
Credit Card Fraudulent Transaction Detection and Prevention
Authors: Salian Prof. S. R.
Published: April 2023

Abstract: In recent years, online payment methods have been used widely as an outcome of the rapid increase in non-cash and digital electronic transactions. Credit cards represent one of the electronic payment methods. With the advancement of online payments in various products and services, the likelihood of credit card fraud has risen compared to the decades-long history of credit cards. The credit card frauds can be detected by evaluating the credit card purchasing patterns using the historical data in order to detect the frauds. This data evaluation can help the banks or other organizations offering credit cards to minimize their losses due to the credit card frauds. The historical data evaluation with the current purchasing patterns requires statistical modeling, which can automatically evaluate the fraudulent patterns and alarm the banks about the transactions. This helps the banks for early detection of the frauds, where they can easily eliminate the credit card frauds by declining the suspected transactions. And also blockchain technology is applied to prevent the hacker to view customers details so that fraudsters can't use stolen credit card information to open new accounts, obtain loans, and engage in other illegal activities. Credit card fraud detection and prevention have become essential for banks and other financial institutions to safeguard their customers' financial transactions. This paper presents an overview of credit card fraud detection and prevention techniques.

Abstract: B2B supply chain funding is a new financial model that aims to make it easier to raise money and improve processes, efficiency, and growth in the supply chain. It is used for online purchases between businesses (B2B), and it is built on the B2B ecommerce platform. For processing and analyzing, you need data on how logistics, business, information, and money move together. Customers who want to take advantage of the speed and ease of e-commerce must not only choose products wisely, but also know and follow all the rules and laws that apply. It is important to avoid getting into trouble with the law. This paper looks at how the B2B platform's online supply chain financial business model creates credit risk and how it works. It then builds a method to reduce risk based on the supply chain financial risk. This article starts by looking at how the B2B platform's online supply chain financial business model creates and operates credit risks. It then builds a system to prevent and control the risks created by this financial business model risk evaluation index system.

Abstract: COVID-19 has brought about drastic change in education systems around the world. Many schools, colleges and universities have chosen online education to complement their courses. For this reason, students have moved to a world of technology where they are motivated to read, practice, and perform in online mode. Students should also be analysed using only online platforms. Therefore, online exams are an integral part of this online education system. But here, students are not supervised by humans, leading to cheating and negligence in exams. Since the exam will be online, an online supervision system is required where candidates can be supervised during the exam without the direct presence of the proctor. In this project, we found a solution to this problem, thus maintaining the academic integrity of the exams. So, the idea included creating a remote monitoring system where students could be monitored via webcam and microphone, which could identify any instances of misconduct in the online examination.

This study aims to determine the effect of doses of biochar and various types of poschar and their interactions on the growth and yield of red chili plants. This research was conducted in Buduk village, Mengwi sub-district, Badung district at an altitude of 65 meters above sea level. This research activity took place from April to July 2021. The design used in this study was a factorial randomized block design (RBD) consisting of 2 treatment factors. The first factor is the dose of biochar (B) which consists of 2 levels (0 and 15 tons/ha), while the second factor is the type of poschar (P) which consists of 3 levels (without poschar, beef poschar, and goat poschar). The results showed that the interaction between the dose of biochar and the type of poschar (BxP) had a significant effect on the number of leaves and fruit number, fruit weight and had a very significant effect on stem diameter, but had no significant effect on plant height, number of productive branches, fruit length, and diameter. fruit per plant.  Biochar treatment had a very significant effect on the variables of plant height, number of leaves, and fruit weight per plant and significantly affected the number of fruits, number of productive branches per plant, and fruit length per plant but had no significant effect on stem diameter. Poschar application showed no significant effect on all observed variables except for plant height which had a significant effect. The highest fresh weight of chili fruit per plant was obtained from the interaction of chicken biochar with no poschar, which was 1326.20 g, followed by the interaction between chicken biochar and goat's poschar, which was 1297.85 g, and the interaction between chicken biochar and beef poschar, which was 1081.71 g which increased by 114.11%, 109.53%, and 74.64% respectively compared to the interaction between the treatment without biochar and without poschar which was 619.41 g.
