| Design and Development of a Compost bin with Integrated Odor control and Compost Utilization | ||||||
The improper disposal of biodegradable kitchen waste in urban Indian homes has emerged as a major environmental concern, contributing to the overloading of landfills and the emission of harmful greenhouse gases like methane. Despite growing awareness, the adoption of domestic composting remains low due to persistent issues such as unpleasant odor, lack of user-friendly systems, space constraints, and minimal understanding of compost utilization. This paper presents a design-led solution aimed at bridging these gaps through the development of a modular, non-electric compost bin that integrates natural odor control mechanisms and compost transformation features.......

| Application of Abaqus Software to Simulate the Influence of Bending Angle and Sheet Thickness on The Inverse Elastic Parameters in the V-Bending Process of Sus 201 Material | ||||||
Precision sheet metal bending is a widely utilized manufacturing process across numerous industries, including mechanical engineering, automotive production, electronics, medical devices, household appliances, and decorative applications. The dimensional accuracy of bent products is significantly influenced by the springback phenomenon - an elastic recovery behavior inherent in metal materials. Among the austenitic stainless steels, SUS 201 has gained widespread adoption due to its high strength under cold working conditions and cost-effectiveness, which results from partially replacing nickel with manganese and nitrogen.......

| Foldable Self-Sterilizing Hospital Bench: A Space-Saving and Hygienic Solution for Modern Healthcare Infrastructure | ||||||
Hospital seating in outpatient departments and waiting areas is often overlooked in design, despite high usage and hygiene concerns. While innovations have advanced in ICU equipment and diagnostics, shared furniture remains outdated. This paper presents the design of a foldable, self-sterilizing hospital bench that improves infection control and space utilization. Developed through ethnographic research and hospital surveys, the bench features UV or spray-based disinfection after each use and folds to reduce its footprint by nearly 50%. Constructed with antimicrobial materials, it ensures durability and easy maintenance. A functional prototype was tested with real users, demonstrating its cost-effectiveness and suitability for both urban and rural healthcare settings.

| Review on Waste PCB Fibers Reinforced Concrete | ||||||
Concrete, which is the world's most prevalent construction material, has become more popular because of the rapid building of urban centers, infrastructure construction, and population increase, particularly in developing countries. Just as the demand for concrete has increased, the demand for electronic devices has skyrocketed due to the digital transformation of nearly every aspect of modern life. Due to the technological advancements and the introduction of less expensive devices, the production of Waste Electrical Equipment (WEE) also increases and waste PCBs (WPCBs) contributes the huge amount of the E-Waste.......

| Evaluation Of Petrophysical Properties of a Field in Deep Off Shore Niger Delta, Nigeria | ||||||
This study involves petrophysical reservoir analysis of four wells SAJI-001, SAJI 004-ST1, SAJI 003-ST1, SAJI-005 using composite well logs. The suite of well logs consists of gamma ray, resistivity, neutron and density log. The conventional methods of well log qualitative and quantitative interpretation were adopted. The main lithology obtained from the gamma ray logs are sands and shale. Four reservoirs were identified and correlated across the four wells. The petrophysical analysis finding result indicates that the average shale 0.08 to 0.23 (Frac), total porosity 0.22 to 0.28 (Frac), effective porosity 0.20 to 0.22 (Frac), permeability 117.5 to 180.32 (mD) and water saturation 0.29 to 0.46 (Frac) and the finding indicates that the reservoir rocks are very good in quality.

This research focuses on evaluating aquifer depths in parts of Alakahia, Rivers State, Nigeria, through the interpretation of resistivity curves derived from Vertical Electrical Sounding (VES). Recognizing the rising demand for groundwater driven by rapid urbanization, the study employed the Schlumberger array configuration at two VES locations to probe subsurface lithology and delineate aquiferous zones. Field measurements of apparent resistivity were processed using partial curve matching and computer-assisted inversion to construct resistivity sounding curves and geoelectric sections. Results revealed a complex multi-layered subsurface typical of the Niger Delta's Benin Formation........

| Fall Risk Assessment in Geriatrics: An HEBED Data Analysis | ||||||
This study investigates postural stability and fall risk assessment based on Human Balance Evaluation Database (HBEDB). Force, moment and center of pressure (CoP) signals were extracted, and sway features like sway path length, area and mean velocity were computed. Then statistical analyses is performed to find correlation coefficients between sway features and clinical scores such as Falls Efficacy Scale (FES), Trail Making Test (TMT), and Mini-BESTest. Finally, a decision tree classifier was implemented to predict fall risk category. The obtained results indicate significant surface condition effects on sway metrics and high classification accuracy in fall risk prediction.

| Lack of Natural Light in Architectural Building and Psychological Influence of Colors | ||||||
As the world developed throughout history and everything else with the addition of electricity, or current, people destroyed natural light and relaxed too much. Through various literature and scientific articles, it can be seen that natural light can never be compared to artificial light. This scientific paper explores the importance and significance of natural light and colors. It also explains what happens to our body when there is no natural light. In various articles and books, we can see research on how important natural light is. Natural light has numerous advantages that the authors have presented in their books. In my paper, I want to write about the psychological reactions that occur to us when we have and when we do not have light. The research is designed as a literature review study. Through my research, I think I have proven the effect of light on the body.
