Understanding the Delamination and Its Effect on Charpy Impact Energy in Thick Wall Linepipe Steel
Abstract: The thick wall linepipes produced from thermo-mechanical-controlled hot-rolled high-strength low-alloy steel (HSLA) plates are characterized by heterogeneity of microstructures through thickness. This microstructural heterogeneity results delamination and is responsible for substantial differences in the toughness behavior of the linepipe steel. The objective of this research work was to investigate these differences in impact energy using Charpy V-notch impact test in correlation with microscopic observations on fractured surfaces of the selected …

A Narrative Review on Osteogenesis Imperfecta and Its Management
Abstract: Osteogenesis imperfecta (OI), sometimes referred to as brittle bone disease, is a heterogeneous illness characterized by short stature, several fractures, and distorted bones. The main contributing factor to OI is mutations in the genes needed to produce type 1 collagen. While severe OI is perinatally fatal, mild OI can occasionally not be detected until maturity. The frequency of Osteogenesis imperfecta ranges from about 1:15,000 to 1:20,000 births. Five kinds of …
