Mass Transfer Process between The Fluid Flow and An Active Cylinder In Cross Flow
Abstract: This paper presents a theoretical and numerical analysis applies to a cylinder in cross flow that is large in comparison with the inert particles, so that the bed may be treated as a continuum. Fluid flow in the packed bed around the cylinder in cross flow was assumed to follow Darcy’s law and the partial differential equation (PDE), resulting from a differential material balance on the solute, was analysed numerically …

Determination of Gatifloxacin in Human Urine by Liquid Chromatography-Tandem Mass Spectrometry
Abstract: Gatifloxacin (GTF) is an antibiotic of the fourth-generation fluoroquinolone family that inhibits the bacterial enzymes DNA gyrase and topoisomerase IV. A reliable, sensitive and selective isocratic reversed phase liquid chromatographic-tandem mass spectrometric (LC-MS-MS) method was developed to determine gatifloxacin (GTF) in human urine. GTF, in urine after solid-phase extraction with SPE cartridge, was analyzed on a C18 column (Symmetric 3.5 μm; 75×4.6 mm i.d) interfaced with a triple quadrupole tandem …

Analytical Solution to Bi-Linear Spring Mass Systems Free Vibration
Abstract: Dynamic systems are generally categorized as linear and non-linear systems based on the analysis approaches developed. Bi-linear spring mass systems form an intermediate category which possesses characteristics of both linear and non-linear systems. Analytical solutions to bi-linear systems cannot in general be reduced to a single equation covering the entire motion domain as in the case of linear systems. Nevertheless, the step-wise linear solutions can be obtained within each domain …

Mass Production Tools and Process Readiness for Uniform Parts—Injection Molding Application
Abstract: A mass production always aims to produce uniform performing products. Production tools such as pressing dies, casting dies and injection moulds, play a significant role by producing uniform parts for achieving final products. Tool complexity increases when multiple cavities are present. These tools pass through several stages of quality maturation, before starting production, where the tool capability for part uniformity can be assessed, corrected and aligned to mass production variables. …

Use of Condom Tamponade to Manage Massive Obstetric Hemorrhage at a Tertiary Center in Rajasthan
Abstract: Conventionally, postpartum hemorrhage (PPH) is defined as blood loss of more than 500 mL, followed by vaginal delivery and 1000 mL followed by caesarean section. PPH is blood loss which causes a 10% drop in hematocritor which threatens the hemodynamic stability of the patient and needs blood transfusion. The purpose of this study is to evaluate the effectiveness of condom tamponade in the management of massive obstetric hemorrhage and to …

Land surface dynamics: A Multiphysics Approach to Modeling Mass Transport
Abstract: Land surface dynamics are governed by complex interactions among hydrological, atmospheric, and geomorphological processes that collectively drive the transport of mass across terrestrial environments. Traditional modeling approaches often isolate individual mechanisms, limiting their ability to capture the coupled feedbacks that shape landscape evolution. This study presents a multiphysics framework for modeling mass transport on land surfaces, integrating fluid flow, sediment transport, heat exchange, and chemical reactions within a unified computational …
