The Role of Cholesterol in Biological Membranes
Abstract: Cholesterol plays the role of a regulator that ensures the correct packaging of the lipid part of the membrane, which is necessary for its normal operation, by influencing on the mobility of the fatty acid tails of membrane lipids: if the membrane is too rigid and there is a danger of "freezing" of fatty acid chains, cholesterol causes it to liquefy, since the chains in its presence become more mobile; …

An in-silico toxicity study of the phytocompounds found in Pongamia pinnata leaves using the ProTox-II web server
Abstract: The aim of the current study was to determine the Insilco toxicity of the phytocompound present in the leaves of Pongamia pinnata. The leaves of Pongamia pinnata have long been used in traditional medicine for their therapeutic properties. Nowadays, herbal toxicity is a common problem caused by incorrect dosage. The FDA reviews the safety and effectiveness of herbal products only in response to patient or health care provider complaints—problems with …

Fabrication and Characterization of PLA-CSP Composites via FDM for Biodegradable Food Packaging
Abstract: In light of the growing need for environmentally friendly alternatives to conventional plastic packaging, this study presents the design of a food-grade, biocompatible packaging material composed of Polylactic Acid (PLA) and packed with coconut shell powder (CSP). One of the most well-known thermoplastic polymers, PLA is produced from renewable resources like sugarcane or maize starch. Its nontoxicity, biodegradability, and adherence to food safety standards and regulations provide energy. Unfortunately, PLA's …

Enhancing Surface Roughness of Polylactic Acid (PLA) 3D-Printed Parts Using CO₂ Laser Scanning: An Experimental Study on Parameter Optimization
Abstract: Fused deposition modeling (FDM) of polylactic acid (PLA) often suffers from poor surface finish due to the inherent layer-by-layer deposition process, limiting its use in high-precision applications. This study investigates CO₂ laser scanning as an efficient post-processing technique to reduce the surface roughness (Ra) of PLA parts while maintaining structural integrity. Specimens (100 × 80 × 5 mm) were fabricated with varying infill densities (35%, 70%, and 100%) to assess …

Seasonal Variations of Air Quality Measures In Warri and Effurun, Delta State, Nigeria.
Abstract: Air quality in Urban Cities like Warri and Effurun has been deteriorating over time. The distribution levels of air pollutants in the Warri and Effurun environments may be related to both natural and man-made factors. In addition to evaluating the quality of rainwater with regard to pH, heavy metals (Fe, Pb, Cd, As, Hg, CU, Zn), and some anions (Cl-, NO3-, SO42-, CO32-), this project study aims to investigate, using …
