Chromatography for Chemical Separation: Types and Uses
Abstract: Chromatography is an analytical tool that is used for separating a variety of chemical mixtures. This technique was developed somewhere during the 1940s to 1950s. Initially, the technique had low efficiency with prolonged time of analysis and reduced detection range. Later, the technique was modified and improved to meet the demands of chemical separation technology. Chromatography is broadly categorized into analytical or preparative. Analytical chromatography is used for small sample …

Mechanical and Microstructure Properties of Al and SiC Reinforced Aluminum-Based Metal Matrix Composite
Abstract: It is becoming increasingly difficult to design new technical materials that are resistant to wear damage and corrosion degradation in severe service circumstances. Unfortunately, even with crucial passive metals, like Al alloys, there is often a compromise between wear and corrosion resistance. Because of the unfavorable galvanic connection between the precipitates and the matrix, precipitates not only harden the material but also accelerate corrosion. This research established that a supersaturated …

Effectiveness of Self-instructional Pamphlet on Knowledge Regarding Burping Technique Among Primi Postnatal Mothers
Abstract: Burping, also known as belching or eructation, refers to the discharge or expulsion of gas from the digestive system, primarily originating from the esophagus and stomach, and exiting through the mouth. It is typically, though not always, accompanied by an audible sound. Burping is a significant responsibility that parents should continue to perform until their child becomes more independent. In certain instances, breastfeeding mothers may need to engage in a …

Deep Reinforcement Learning-Based MPPT for PV Systems Under Partial Shading: A Hybrid Metaheuristic-Optimized Control Framework.
Abstract: Partial shade and quickly changing environmental conditions make Maximum Power Point Tracking (MPPT) in photovoltaic (PV) arrays particularly difficult. In these situations, traditional algorithms frequently fail to find the global optimum or experience sluggish convergence and steady-state oscillations. To obtain reliable, real-time MPPT under non-uniform irradiance, this research suggests a hybrid control architecture that combines a deep recurrent reinforcement learning (DRL) agent with metaheuristic-based parameter optimization and a digital-twin training …
