“FORCE-DISPLACEMENT TRADE OFF” OF RCC BUILDING LOCATED AT VARIOUS SEISMIC ZONES AND SITE CONDITION ADOPTING TIME-HISTORY ANALYSIS
Abstract: Earthquake-resistant or aseismic design are considered to protect buildings to some or greater extent from earthquakes. The force-displacement trade off of structures located in various seismic zones are different in nature depending on intensity of earthquake. No structure can be fully immune to damage from earthquake, the vulnerability can be reduced for safety and durability. The force-displacement behavior of a particular structure can be modified to withstand seismic occurrence preventing …

Dynamic Vibration and Damping Analysis of Sustainable Nano-Reinforced Polymer Composite Elements for Vehicle Suspension Applications
Abstract: This paper presents an analytical investigation into the dynamic vibration characteristics of nano-reinforced polymer composite elements intended for vehicle suspension applications. A single-degree-of-freedom (SDOF) quarter-car model is employed to derive fundamental expressions for natural frequency, damping ratio, logarithmic decrement, and displacement transmissibility. The primary contribution lies in establishing explicit analytical linkages between material-level viscoelastic properties specifically storage modulus and loss modulus and system-level suspension parameters including stiffness and damping coefficients. …

A Review on the Interconnection Between Drug Design and Controlled Drug Delivery Systems
Abstract: Drug discovery and delivery are two branches of science that have historically developed as independent areas of discovery – one focused on optimizing the properties of molecules for biological activity, and the other on controlling the rate, site, and duration for drug release. However, in contemporary pharmacy, these two areas have merged into a single integrated approach – where drug discovery and delivery strategies co-influence each other at each point …

A Statistical Analysis of Cephalic Index of the Different Communities of Assam Brought for Autopsy at Department of Forensic Medicine, Gauhati Medical College and Hospital
Abstract: Cephalic Index also known as ‘Cranial Index’ or ‘Index of Breadth’ is one of the important parameters that help to differentiate human races. The cephalic index was first described by a Swedish anatomist, Anders Retzius (1796–1860) and was first used in physical anthropology in classifying ancient human remains of Europe. It is one such data obtained from skull which can aid in identification of a particular race or community, describe …

Abstract: Exergy and heat flow have been numerically investigated for flame impinging on flat circular plates. The maximum work available when the system is brought to thermodynamic equilibrium state with its surrounding is known as the exergy of a system. This state of equilibrium of the system depends on the pressure, temperature, and composition of environment. Efficiency based on exergy is otherwise known as the second-law efficiency which measures the usefulness …

Activated Carbon Materials as Ideal Adsorbents for the Desulfurization of Fossil Fuels
Abstract: Removal of organosulfur compounds from diesel is of interest from scientific, social, economic, and environmental viewpoints. Production of clean fuel remains a primary goal of the petroleum refining industry. The reduction of sulfur content below stringent ppm levels in diesel fuels becomesincreasingly challenging due to the presence of sterically hindered sulfur compounds, such as 4,6- dialkyldibenzothiophenes, which are resistant to removal over conventional supported mixed sulfide hydrodesulfurization catalysts. Consequently, alternative …

Influence of Dielectric and Active layer Thickness on MgZnO Thin Film Transistor Electrical Characteristics
Abstract: From last decades, Thin Film Transistors Technology uses low-k dielectric material as an insulator. Insulator thickness plays an important role in device dimension. The insulating layer also known as the gate oxide separates the gate electrode from the channel region of the transistor. If the insulating layer is too thin, there is a greater chance that electrons can tunnel through the oxide layer, leading to leakage current. To mitigate this …

The Patient’s Dilemma: An approach in Medical Decision Making using the Prisoner’s Dilemma Model and the Prospect Theory
Abstract: Prospect theory suggests that when people are faced with uncertain outcome, they may be risk seeking or aversive, depending on the utility value. While Prisoner’s dilemma shows that suboptimal choices are made if people seek their own gain only. Patients’ demand in decision making during the recent years evolved this dilemma. Through a mathematical approach and survey, the doctor-patient involvement in decision making has been explored. A hypothetical model was …
