Structural Analysis and Design Considerations for Flyover Bridges
Abstract: AbstractBridges serve as essential components of transportation networks, facilitating the movement of vehiclesand pedestrians across obstacles, such as rivers, valleys, and roads. The stability of a bridge largelydepends on the strength and structural capacity of its deck slab. The deck slab must endure both its ownweight and the additional loads imposed by vehicles. A key aspect of bridge design is assessing theflexural stress acting on the deck slab to determine …

Autoimmune Polyglandular Syndrome Type 1 (APS-1): A Rare Yet Crucial Condition to Recognize
Abstract: Autoimmune Polyglandular Syndrome Type 1 (APS-1), also known as Autoimmune Polyendocrinopathy-Candidiasis-Ectodermal Dystrophy (APECED), is a rare autosomal recessive disorder caused by mutations in the AIRE (Autoimmune Regulator) gene. This syndrome is characterized by a triad of chronic mucocutaneous candidiasis, hypoparathyroidism, and adrenal insufficiency, although it can affect multiple other organ systems. APS-1 arises from a failure of central immune tolerance, resulting in autoimmunity against various endocrine and non-endocrine tissues. The …

Stabilization of Foundation Base Soil for Enhanced Bearing Capacity and Lateral Load Resistance
Abstract: Abstract The foundation of any structure plays a pivotal role in ensuring its stability and durability. The soil beneath the foundation must possess sufficient bearing capacity to support the structure's load, while also resisting the uplift pressure exerted by groundwater, especially in saturated conditions. Inadequate bearing capacity can lead to settlement or even structural failure. Additionally, the surrounding soil must be stabilized to prevent lateral movement and ensure the foundation's …
