SeedChain: A Secure and Transparent Blockchain-Driven Framework to Revolutionize the Seed Supply Chain
Authors: Ahuja Rohit , Chugh Sahil , Singh Raman 
Published: April 2024

Farming is a major sector required for any nation to become self-sustainable. Quality seeds heavily influence the effectiveness of farming. Seeds cultivated by breeders pass through several entities in order to reach farmers. The existing seed supply chain is opaque and intractable, which not only hinders the growth of crops but also makes the life of a farmer miserable. Blockchain has been widely employed to enable fair and secure transactions between farmers and buyers, but concerns related to transparency and traceability in the seed supply chain, counterfeit seeds, middlemen involvement, and inefficient processes in the agricultural ecosystem have not received enough attention. To address these concerns, a blockchain-based solution is proposed that brings breeders, farmers, warehouse owners, transporters, and food corporations to a single platform to enhance transparency, traceability, and trust among trust-less parties. A smart contract updates the status of seeds from a breeder from submitted to approved. Then, a non-fungible token (NFT) corresponding to approved seeds is minted for the breeder, which records the date of cultivation and its owner (breeder). The NFT enables farmers to keep track of seeds right from the date of their cultivation and their owner, which helps them to make better decisions about picking seeds from the correct owner. Farmers directly interact with warehouses to purchase seeds, which removes the need for middlemen and improves the trust among trust-less entities. Furthermore, a tender for the transportation of seeds is auctioned on the basis of the priority location locp, Score, and bid_amount of every transporter, which provides a fair chance to every transporter to restrict the monopoly of a single transporter. The proposed system achieves immutability, decentralization, and efficiency inherently from the blockchain. We implemented the proposed scheme and deployed it on the Ethereum network. Smart contracts deployed over the Ethereum network interact with React-based web pages. The analysis and results of the proposed model indicate that it is viable and secure, as well as superior to the current seed supply chain system.
First-Principles Study of Doped CdX(X = Te, Se) Compounds: Enhancing Thermoelectric Properties

Published: April 2024

Isovalent doping offers a method to enhance the thermoelectric properties of semiconductors, yet its influence on the phonon structure and propagation is often overlooked. Here, we take CdX (X=Te, Se) compounds as an example to study the role of isovalent doping in thermoelectrics by first-principles calculations in combination with the Boltzmann transport theory. The electronic and phononic properties of Cd8Se8, Cd8Se7Te, Cd8Te8, and Cd8Te7Se are compared. The results suggest that isovalent doping with CdX significantly improves the thermoelectric performance. Due to the similar properties of Se and Te atoms, the electronic properties remain unaffected. Moreover, doping enhances anharmonic phonon scattering, leading to a reduction in lattice thermal conductivity. Our results show that optimized p-type(n-type) ZT values can reach 3.13 (1.33) and 2.51 (1.21) for Cd8Te7Se and Cd8Se7Te at 900 K, respectively. This research illuminates the potential benefits of strategically employing isovalent doping to enhance the thermoelectric properties of CdX compounds.

O Transtorno do Déficit de Atenção e Hiperatividade (TDAH) é um distúrbio neurocomportamental prevalente, impactando tanto crianças quanto adultos. Esta revisão integrativa destaca a importância dos ácidos graxos ômega-3, especialmente o EPA e o DHA, na saúde cerebral e no manejo do TDAH.
A literatura revisada enfatiza o papel fundamental da dieta no desenvolvimento cerebral, com a ingestão adequada de ômega-3 associada à melhoria da função cognitiva e comportamental. Estudos clínicos demonstram que a suplementação de ômega-3 pode reduzir os sintomas do TDAH, especialmente hiperatividade, impulsividade e desatenção.
Embora a suplementação de ômega-3 ofereça benefícios promissores para o manejo do TDAH, questões sobre dosagem e duração do tratamento ainda estão em debate. Enquanto algumas recomendações sugerem doses específicas para gestantes e lactantes, há variações nas diretrizes internacionais. Além disso, a eficácia da suplementação parece depender da dose e proporção de EPA e DHA administradas.
Portanto, embora os resultados apresentados nesta revisão ofereçam insights valiosos para a prática clínica, são necessárias mais pesquisas para estabelecer diretrizes claras de dosagem e duração do tratamento. Isso destaca a importância de uma abordagem individualizada no diagnóstico e tratamento do TDAH, considerando os benefícios potenciais da suplementação de ômega-3.

Results: The outpatient service was the highest (67.4 %); having average ages between 1 to 89 years. Regarding the “N2” and “E” genes, it was determined that there is no significant difference in relation to the age group, however, when performing inferential analysis, for the type of protein variable, it was concluded that there was a significant difference. Conclusions: SARS COV 2 is an etiology, present in different age groups, being more susceptible over 50 years of age, in addition to the threshold value of the genes, it is not usually related; this value may vary depending on the methodology used.
Dramatization of Agency and Ecological Consciousness in How Beautiful We Were by Imbolo Mbue and Oil on Water by Hellon Habila
Authors: Mwaga Robert , Mutie Stephen , Gaita Murimi 
Published: April 2024

This paper interrogates how authors deploy characters to represent ecological consciousness. The paper draws illustrations from Imbolo Mbue’s How Beautiful We Were and Hellon Habila’s Oil on Water to examine how agency is dramatized through characterization. The paper explores character agency within the subversive space of Bakhtin’s carnival laughter to represent their ecological consciousness. To ground the paper into an analytical perspective, the discussion identifies and discusses the distinct characterizations the two texts' authors employ to represent the characters’ ecological consciousness. The article argues that the writers of the chosen texts effectively use characterisation to create compelling ecological narratives that teach about the need to address environmental degradation. Additionally, the discussion reveals how the two writers depict ecological awareness via the characteristics of carnival shown by the characters. Furthermore, it is worth mentioning that characters have a crucial role in delivering sermons about the gruesome consequences of environmental degradation. As a result, the components of carnival, such as craziness, clowns, and heroic characterizations, are used to undermine and challenge the impact of environmental degradation

Heavy-duty trucks are the primary contributor to the global emissions of greenhouse gases. Because of this, electric haulage has seen significant growth in popularity. Electric heavy-duty trucks aren't widely adopted because of their limited range, payload capacity, and high prices. Electric axle systems, sometimes known as "E-Axles," are capable of electrifying heavy-duty vehicles effectively. The motor, power electronics, and gearbox are all combined into one unit in an E-axle. E-axles that are devoid of motors and gearboxes have the potential to boost performance while also reducing weight and fuel consumption. Heavy-duty automobiles are similar to them. E-axles have the potential to increase the fuel efficiency, flexibility, and emissions of heavy-load trucks. The e-axles are being inspected. E-axles for heavy-duty trucks bring both issues and opportunities concerning finances, infrastructure, and costs. Examine the performance standards as well as the technology behind batteries. This paper provides an introduction to MATLAB Simulink, which focuses on engineering and science. Simulink facilitates the design, simulation, and evaluation of systems. This article demonstrates the fundamental principles, features, and benefits of Simulink through the application of system modeling, control design, and dynamic simulation. It presents Simulink methodologies, libraries, and blocks, as well as interactive simulations.

ObjectiveTo determine how serologic responses to coronavirus disease 2019 (COVID-19) vaccination and infection in immune-mediated inflammatory disease (IMID) are affected by time since last vaccination and other factors.MethodsPost–COVID-19 vaccination, data, and dried blood spots or sera were collected from adults with rheumatoid arthritis, inflammatory bowel disease, systemic lupus erythematosus, ankylosing spondylitis and spondylarthritis, and psoriasis and psoriatic arthritis. The first sample was collected at enrollment, then at 2 to 4 weeks and 3, 6, and 12 months after the latest vaccine dose. Multivariate generalized estimating equation regressions (including medications, demographics, and vaccination history) evaluated serologic response, based on log-transformed anti–receptor-binding domain (RBD) IgG titers; we also measured antinucleocapsid (anti-N) IgG.ResultsPositive associations for log-transformed anti-RBD titers were seen with female sex, number of doses, and self-reported COVID-19 infections in 2021 to 2023. Negative associations were seen with prednisone, anti–tumor necrosis factor agents, and rituximab. Over the 2021-2023 period, most (94%) of anti-N positivity was associated with a self-reported infection in the 3 months prior to testing. From March 2021 to February 2022, anti-N positivity was present in 5% to 15% of samples and was highest in the post-Omicron era, with antinucleocapsid positivity trending to 30% to 35% or higher as of March 2023. Anti-N positivity in IMID remained lower than Canada’s general population seroprevalence (> 50% in 2022 and > 75% in 2023). Time since last vaccination was negatively associated with log-transformed anti-RBD titers, particularly after 210 days.ConclusionOurs is the first pan-Canadian IMID assessment of how vaccine history and other factors affect serologic COVID-19 vaccine responses. These findings may help individuals personalize vaccination decisions, including consideration of additional vaccination when > 6 months has elapsed since last COVID-19 vaccination/infection.

This study aimed to obtain and characterize soy flours from whole (WG) and shelled grains (SG) of the conventional cultivar Vmax and special cultivars used for human consumption, BRS 267 and BRS 257. For lipoxygenase enzyme inactivation, the WGs and SGs of BRS 267 and Vmax were bleached at 98 °C for 5 min, roasted at 150 °C for 30 min, milled and finally sieved through a size 40 mesh to obtain the flours. These flours were analyzed for proteins, lipids, isoflavones, Kunitz trypsin inhibitor, their nitrogen solubility index and their protein dispersibility index. The grain heat treatments caused a reduction in protein solubility, an increase in aglycone isoflavones and an 80% reduction in levels of the Kunitz trypsin inhibitor. Flours from bleached WGs were brown in color. Flours from BRS 267 had higher protein levels, while those from the cultivar Vmax had the highest lipid content. Flours from BRS 257 had greater protein solubility. Thus, varieties of special soybeans, genetically enhanced for human consumption, can be processed for better quality soy foods, promoting their acceptance.
