Analysis of Surface Finish of Different Metallic Materials
Abstract: This study investigates surface processing techniques aimed at achieving a surface roughness (Ra) value of < 2.5 for various materials including gray iron, steel, pure copper, aluminum, and brass. Surface roughness plays a crucial role in determining the functional and aesthetic properties of machined components. The attainment of a specific Ra value demands precise control over machining parameters and selection of appropriate finishing processes. For steel, machining operation grinding followed …

Study of Heavy Metal ion adsorption from Synthetic Wastewater with the help of biomass and analysis of Mathematical Model
Abstract: The biofilm matrix is a mixture of secreted polymers, metabolites and nutrients ingested, lysis solution products, and even particle debris. This matrix, which is polyanionic by nature, is essential for the activated carbon of metal cations. In this study, the heavy metal adsorption mechanism in biofilms is modelled in one spatial dimension. The numerical method is a free-boundary value issue for nonlinear parabolic and quadratic partial differential equations. Parabolic equations …

Response of Zea mays to Rhizophagus Intraradices with 50% Nitrogen and Phosphorus Fertilizer Prevents the Release of N2O From the Soil
Abstract: The healthy growth of Zea mays (maize) requires NH4NO3/PO4--3 fertilizers (ammonium nitrate and phosphates), are applied in unregulated doses, are associated to denitrification, generating greenhouse gases, causing global warming, loss of soil productivity, and pollution of surface water in case of phosphates. An alternative is to decrease and optimize the dose of NH4NO3/PO4--3 by applying arbuscular vesicle fungi (AVF), to optimize, the dose of nitrogen and phosphorus fertilizers, AVF endosymbionts …

Nanotechnology Based Drug Delivery System in Tuberculosis: Review
Abstract: From near the beginning centuries to present life Tuberculosis remains the world-wide disease without any limitations. In the other hand, in some cases in the infected individuals the disease remains in a dormant state. In this stage the treatment is hard as the lipid mycobacterial wall is thick & the delivery of drug inside the bacterial cell is difficult. Due to this new face of TB it becomes the major …

Heat Generated Simulation with Bacteria and Fungi inCrude Oil Remediation in an Aerated Lagoon
Abstract: Studies on the heat generated by bacteria and fungi in an aerated lagoon were monitored by theapplication of MATLAB computed software simulation. Mathematical models were developed in termsof substrate utilization by microbes and correlated with the Monod’s equation model which revealedthe trend of heat generated at different operating temperature of 15°C, 30°C, 45°C, 60°C, 75°C, 90°C,105°C and 120°C. The heat generated varies with increase in the microbial concentration as favoredby …
