Analytical Evaluation of heavy metals in eyeshadows: A Risk assessment and Implications for Public Health Regulatory Reforms in Nigeria
Abstract: This study employs advanced analytical techniques to assess heavy metal contamination (Pb, Cd, Cr, Ni, Zn) in 18 commercially available eyeshadow products (local and imported) from Owerri Metropolis, Nigeria. Quantification was conducted using atomic absorption spectroscopy (AAS), while risk evaluations incorporated chemometric modeling approaches. Results revealed significant contamination in locally manufactured brands, particularly those containing calabash chalk (Nzu) as a base ingredient. Lead and nickel concentrations reached 166.58 ± 6.5 …

Applications of Sesame Residues as Sorbents for Oil Removal from Produced Water
Abstract: Large amounts of produced water are produced in tandem with the production of crude oil. Both dissolved and dispersed oil are present in produced water, which can contaminate the environment and pose health risks to people. In this study, the oil component, cadmium, and lead ions were extracted from the generated water using sesame residues and agricultural wastes. The sesame residues were dried, size-reduced, and ground. Standard techniques were used …

High Performance 64-Bit Vedic MAC with Logic BIST Features
Abstract: Multiply and Accumulate (MAC) is a very important operation in most of the DSP applications such as FIR/IIR filters, convolutions, and FFT computations. Therefore, every DSP processor will incorporate a hardware MAC for high-performance operations. However, most of the MAC architectures do not have self-testing features. It is very essential to embed self-testing features in the MAC design for accurate and reliable operation thus avoiding the need for expensive external …

Evidence-Based Nursing Care and Quality of Life of Coronary Artery Disease Patients: A Systematic Review
Abstract: Globally, 60% of deaths are attributed to non-communicable diseases (NCDs), which include cardiovascular diseases (CVDs), cancer, chronic respiratory diseases, diabetes, and others. Among these, ischemic heart disease and stroke are the leading causes, collectively accounting for approximately 17.7 million deaths annually. According to the World Health Organization (WHO), India contributes to nearly one-fifth of these deaths, with cardiovascular diseases affecting the Indian population almost a decade earlier compared to their …

Overview Of 3D Printing Technology with Different Materials and Applications
Abstract: The aim of the project is to perform thermal analysis of the 3D printed model using SOLIDWORKS 2018, create the frame using cutting and drilling machines, and combine all parts of the frame using fasteners and fire electrical connection. When the 3D printer is built, the thermal efficiency of brake discs produced from PLA (polylactic acid) and carbon filaments will be analyzed. Also, parameters that do not work in CURA …
