The paper presents a theoretical analysis of heat transfer in heated tube bank, based on the Nusselt number computation as one basic dimensionless criteria. To compute coefficient, reference temperature must be determined. Despite value significance, quantity has several different formulations, which leads to discrepancies results. This investigates inline and staggered banks, made up 20 rows, ...

The present study considers steady laminar two-dimensional incompressible flow over both in-line and staggered flat tube bundles used in heat exchanger applications. The effects of various independent parameters, such as Reynolds number (Re), Prandtl number (Pr), length ratio (L=Da), and height ratio (H=Da), on the pressure drop and heat transfer were studied. A finite-volume-based FORTRAN code...

Tracheotomy is used to keep and control airways open and protect them in head and neck operations.1-3 Tracheotomy is opening a direct airway through an incision in the trachea observed as a stoma in the lower throat and it is usually performed in serious head and neck traumas, tumors, bleedings and cases that intubation with endotracheal tube is not possible. This method has several advantages ...

For banks and financial institutions, credit risk had been an essential factor that needed to be managed well. Credit risk was the possibility that a borrower of counter party would fail to meet its obligations in accordance with agreed terms. Credit risk; therefore arise from the bank’s dealings with or lending to corporate, individuals, and other banks or financial institutions.  Credit risk...

Abstract Introduction/Objective Patients with hematological cancer routinely receive red blood cell (RBC) transfusions in the outpatient infusion clinical setting as part of their therapy. Typically, RBCs are delivered to clinic via pneumatic tube (P-tube). However, due recent expansion hospital footprint and new location transfusion services, P-tube encountered challenges that impacted reliabi...

" Coagulase Plates" When human blood bank plasma is mixed with nutrient agar in a concentration of about 12 to 15O% v v and poured into Petri dishes at a temperature of 45° C. the mixture sets as a clear gel. Staphylococci inoculated on to this medium develop opaque haloes around the colonies in 12 to 48 hours if they produce coagulase (Lack and Wailling, 1954). The advantages of the plate meth...

In general Pakistan is an agricultural country, most of its area including lower Indus basin (LIB) lies in arid and semi-arid zones, where irrigation by canal water and groundwater is only option. Due to continuous seepage from canal irrigation network and infiltration from irrigated lands; without adequate provision of natural and artificial drainage and its appropriate outlet, water-logging a...
