It's a new way of understanding the world and interacting with it that is available to today's generations. These connected technologies undoubtedly play a major role in the competitiveness of human actions in their social and organizational lives. Businesses, government departments and public services are all concerned, given the role they play in economic performance, especially in Burkina Faso, where 80% of the population are farmers and agribusiness is seeing the light of day more and more. These technologies, known as IoT, give an arrange of interconnected gadgets and sensors for the industry that collects and share information. IoT can be inserted in soil, crops, apparatus, and animals to screen temperature, stickiness, soil dampness, supplement levels, and creature behavior. Encourage, this assembled information is at that point analyzed & utilized for making educated choices around water system, fertilization, illness avoidance, and in general cultivate administration.

The study aims to understand and optimize the complex behaviour of fluid flow and heat transfer in this system, which has significant implications for engineering and industrial applications. The Magneto-Casson fluid, characterized by its non-Newtonian behaviour and yield stress, interacts with stretchy material and tiny particles, introducing unique flow characteristics and thermal properties. Viscous dissipation, resulting from internal friction, further influences the convective heat transfer process. Mathematical models are developed and solved by employing a numerical technique through the Runge-Kutta Fehlberg scheme coupled with the shooting method to investigate these phenomena comprehensively. The results are deliberated using several graphs on the dimensionless profiles. The results showed that there is a decline in the momentum boundary film as the magnetic field improves due to the effect of the Lorentz force. Also, an increase in the Casson fluid term raises the viscosity and thereby resists the fluid motion.","PeriodicalId":124795,"journal":{"name":"Physical Science International Journal","volume":"242 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121873307","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It should be noted that the use of building materials evolves in step with population growth. However, their production must have a clear positive impact on the environment and offer viable solutions for reducing energy consumption during it is application. However, these materials rarely meet the mechanical requirements for using in housing construction. The aim of this study is to investigate the potential use of diatomite in the manufacture of compressed earth bricks. Diatomite is used at between 5% and 50% in two clay soils to determine its physico-mechanical properties. The study focused on shrinkage and mass loss, density, porosity, flexural strength, compressive strength and splitting tensile strength of the composites. The results show that the incorporation of diatomite improves the linear shrinkage of compressed earth blocks and increases their porosities. The dry density of compressed earth block decreased considerably with increasing percentages of diatomite, which also led to a reduction in mechanical strength. This reduction in mechanical strength is linked to the physicochemical characteristics of diatomite. According to a number of relevant standards in the literature, which can be used in building construction set minimum permissible strengths at 2 MPa in simple compression and 0.1 MPa in bending and indirect tension, composites made from two clay soils and diatomite.","PeriodicalId":124795,"journal":{"name":"Physical Science International Journal","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125812124","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Long term mean metrological data and physical characteristics of the catchments were used as an input to the model. The input data were manipulated using Arc- GIS tools. Results of this model depicted that about 73.13% and 19.96% of the precipitation in the study area was lost through evapotranspiration and surface runoff respectively. However, 7% of it replenished the groundwater. The annual runoff and groundwater recharge estimated in WetSpass model accumulated using Arc-GIS were verified using the annual runoff gauged records and base flow measurements. Accordingly the accumulated runoff and base flow derived from the WetSpass model using Arc-GIS software results were quite close to the observed runoff and base flow values measured in the gauging points. Therefore, WetSpass model is appropriate model in estimating water balance components in the study area.","PeriodicalId":124795,"journal":{"name":"Physical Science International Journal","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129233953","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hammer mills have enjoyed major use in the pulverization and/or grinding of granular objects or similar solid materials into smaller sizes or particles. Major parts of the Conventional hammer mills are shaft, free swinging hammers, sieve, hopper, electric motor, and discharge chute amongst other component parts. Functional hammer mills operated within the urban settlements in Nigeria are mostly imported and expensive to acquire by rural farmers thus the need to develop one that can be easily acquired by the rural farmers as well as ease of maintenance. The grinding process is achieved using a hammer in beating the material fed into fine particles; the fineness aimed depends on the beating operation that happens when the Hammers hit the grain particles across the inner walls of the grinding or crushing chamber. The final size of the ground sorghum is a product of the aperture size which ranges from 87µm to 2 mm. This particular design has its major focus on the analytical design of an improved compact hammer mill that employs a single-acting operation to pulverize, move and push out pulverized bulk material particles against gravity through a cyclone. This machine consists of some vital components like the loading hopper and tray, low and high-pressure throats, shaft, spacing discs, hammers, axial fan, gate, cyclone, electric motor, bearings and pulley. This fabricated hammer mill is compact, and cost-effective to produce, operate and maintain. Its commercial production and use will be a reprieve to rural farmers as well as promote local content technology in Nigeria. The economic evaluation of the machine revealed that the material worth of US$85.20 was used for its construction. Testing and performance evaluation carried out on the machine showed that the machine had a 98.4% crushing and grinding efficiency.","PeriodicalId":124795,"journal":{"name":"Physical Science International Journal","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131542760","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
