Selection of Grade of Concrete & Grade of Steel
Abstract: Abstract In structural engineering, understanding the load distribution between steel and concrete is crucialfor ensuring the safety and stability of reinforced concrete structures. The load-bearing capacity ofboth materials, steel and concrete, is dependent on their respective characteristic strengths, whichinclude compressive, tensile, bending, and shear strengths. The behavior of a reinforced concretestructure under various loads is influenced by the interaction between these two materials, wheresteel typically handles tensile and bending stresses, …

Low-graded coals to upgrade
Abstract: Coal can be defined as a chemically and physically heterogenous, “combustible”, sedimentary rock consisting of both organic and inorganic materials. Organically, coal consists primarily of carbon, hydrogen, and oxygen, with lesser amounts of sulphur and nitrogen. Inorganically, coal consists of a range of ash-forming compounds distributed throughout coal. Major types of analysis are proximate analysis, ultimate analysis and calorific value analysis. Heat value or calorific value determines energy content of …

CFD-subset-FVM-based MATLAB-simulation of Heat Transfer in High Grade Cold Storage Augmenting Cryogenic Energy Storage System by Circulating Natural Gas as Working Fluid : Conceptual Review
Abstract: Abstract. Cryogenic Energy Storage (CES) improves power grid with renewable intermittent power sources. In CES, off-peak excess electricity liquefies air or natural gas. Cryogen is stored in large dewar tanks for long periods of time. Whenever electricity need is in peak, work is recovered from cryogen by a power cycle using waste heat. Many researchers focus on liquid air energy storage (LAES). But, natural gas is promising working fluid for …

A Case of Pilocytic Astrocytoma: A Low-Grade Glioma (LGG) During Pregnancy that Requires Medical Termination of Pregnancy (MTP)
Abstract: Pilocytic astrocytoma (PA) is typically a slow-growing astrocytoma and is therefore considered the ‘most benign’ of all the astrocytoma. PA is often encountered in relatively young individuals, including women of childbearing age, but growth is rarely reported. Its management is particularly challenging since anti-tumor therapy is required and the impact on the fetus or the pregnancy would require consideration, or the pregnancy would have to be discontinued, depending on the …

A Study on Self Compacting Concrete using Portland Pozzolana Cement
Abstract: Self-compacting concrete (SCC) is a type of highly flowable concrete that fills each and every corner of congested formwork without the need for mechanical vibration as it is placed by means of its own weight. Generally, the SCC is prepared by using Ordinary Portland Cement (OPC) with mineral and chemical admixtures. Portland Pozzolana Cement (PPC) itself contains some amount of fly ash, thus given the motivation to prepare the SCC …
