Bone Mass Density and Osteomyelitis in Elderly-An Overview
Abstract: Bone mass density (BMD) plays a critical role in skeletal health, particularly in the elderly, where age-related bone loss increases susceptibility to infections such as osteomyelitis. Osteomyelitis, a severe bone infection often caused by Staphylococcus aureus, is more prevalent in older adults due to factors such as osteoporosis, impaired immune function, diabetes, and peripheral vascular disease. Reduced BMD weakens bone integrity, making it more vulnerable to fractures and microbial invasion, …

Article on Density Functional Theory Simulation: A Review
Abstract: Density Functional Theory (DFT) is a powerful computational approach in quantum mechanics, widely utilized for studying the electronic structure of atoms, molecules, and solids. It treats electron density as the central quantity, bypassing the complexities of solving the Schrödinger equation for individual electrons. The Hohenberg-Kohn theorem establishes that a system's ground-state energy uniquely depends on its electron density, facilitating a focus on this fundamental property. In DFT, the total energy …

Assymmetrical development and urban Agglomeration issues in Shilong
Abstract: Abstract: The expansion of the hill city of Shillong has sprawled into an urban agglomeration that lacks organised urban management with a population that is not as well served through development schemes as the core municipal area. Over the past few decades, growth in the Municipal area has gradually decreased as population density has overshot acceptable limits. At the same time, new Census towns have enlarged the urban agglomeration with …
