Thermo-Fluid Characterization of Corrugated U-Tube Shell-and-Tube Heat Exchanger with Polymer Composite Tube Wall: A Combined CFD and Experimental Investigation
Abstract: Shell-and-tube heat exchangers built with metallic tubes work well thermally, but corrosion problems, extra weight, and the inability to adjust the wall’s thermal properties through material choice remain genuine engineering headaches, particularly for corrosive or weight-critical applications. Over the past few years there has been a fair amount of interest in replacing metal tubes with polymer composite alternatives, since blending thermally conductive fillers — graphite nanoplatelets, boron nitride platelets and …

Effectiveness of Twill Technique Vs Endotracheal Tube Holder on ETT Securement: A Comparative Study
Abstract: Endotracheal intubation is an urgent procedure which is performed on patients who are unconscious and can’t breathe by their own. Endotracheal Intubation keeps an airway open and helps to prevent chocking. When the patient is intubated, maintaining the endotracheal tube placement is essential. In case Endotracheal Tube is not secured, even basic nursing management can cause tubing slippage which is a major factor in causing airway trauma or injuries Aim: …

GeneXpert MTB/RIF Assay (PCR Mycobacterium Tuberculosis): A Revolution in Management of Tuberculosis
Abstract: Background: Workup of pulmonary tuberculosis depends upon sputum microscopy. Sputum microscopy is less sensitive, human resource dependent and time consuming. Sometimes, it lead us to a delay in the diagnosis and may result in the spread of the disease. This seriously disturbs TB control program. There is a need for a more sensitive method. Similarly, early detection of rifampicin resistance is also of utmost importance to prevent MDR strains from …
