Patient Satisfaction with Healthcare Services: Bangladesh Perspective

Patient satisfaction is a useful measure for providing a quality benchmark for healthcare services. Concern about the quality of healthcare services in Bangladesh has led to a loss of confidence in healthcare providers, low use of public health facilities and increased outflows of patients from Bangladesh to hospitals abroad. The key obstacles to access to health services are insufficient infrastructure and poor quality of existing facilities, lack of medical equipment, scarcity of doctors due to high patient load, long distance to the facilities and long waiting times until facilities have been reached, very short appointment hours, lack of empathy of health professionals, their generally callous and casual attitude, aggressive pursuit of monetary gains, poor levels of competence and, occasionally, disregard for the suffering that patients endure without being able to voice their concerns-all of these service failures are reported frequently in the print media. Such failures can play a powerful role in shaping patients\u27 negative attitudes and dissatisfaction with healthcare service providers and healthcare itself

Experimental analysis and comparison of performance characteristics of catalytic converters

The purpose of this chapter is to present the results of an experimental study of the performance and conversion efficiencies of ceramic monolith three-way catalytic converters (TWCC) employed in automotive exhaust lines for the reduction of gasoline emissions. Two ceramic converters of different cell density, substrate length, hydraulic channel diameter and \vall thickness were studied to investigate the effect of varying key parameters on conversion efficiencies and pressure drop. Based on the emission test results, the conversion efficiencies of HC from both converters were calculated and evaluated

Experimental analysis to determine the relationship between noise and back pressure for muffler design – Part II: Experimental results

This chapter describes the final part of the detailed methodology of relationship between noise and back pressure for muffler design. This part includes experimental setup, experimental procedures, results and discussions. The experimental data show a general shape of an average design ofthe muffler which would be the most suitable for the test car

Exhaust system optimization using GT- Power

The exhaust system consists of the exhaust manifold, the header, the catalytic converter, the muffler, and the tailpipe. Certain flow characteristics must be met for the optimal performance of the exhaust system. The main objective of this chapter is to design exhaust system (particularly the exhaust manifold) using GT-Power software and to optimize its performance

Experimental analysis and simulation of catalytic converters

The purpose of this chapter is to present the results of an experimental study ofthe performance of ceramic monolith three-way catalytic converters (TWCC) employed in automotive exhaust lines for the reduction of gasoline emissions. Two ceramic converters of different cell density, substrate length, hydraulic channel diameter and wall thickness were investigated. After completing the test, the converters were cut to extract the substrate or 'honeycomb' inside the housing and being analyzed for microstructure and materials composition using Scanning Electron Microscopy (SEM) and Energy Dispersive Analysis (EDX). Simulation program using commercial computational fluid dynamics (CFD) software packages, GAMBIT and FLUENT 6.1 was used to verify experimental results

Experimental analysis to determine the relationship between noise and back pressure for muffler design – Part I: Muffler design requirements

This chapter describes part of the detailed methodology of relationship between noise and back pressure for muffler design. Starting with a brief introduction, an attempt is made here to present different steps of muffler design considering the relation between noise and back pressure. The design ofthe muffler chamber separation and arrangement is essential in determining the muffler characteristics. Some design considerations are proposed in order to come up with an optimum muffler design

Local structure of In_(0.5)Ga_(0.5)As from joint high-resolution and differential pair distribution function analysis

High resolution total and indium differential atomic pair distribution functions (PDFs) for In_(0.5)Ga_(0.5)As alloys have been obtained by high energy and anomalous x-ray diffraction experiments, respectively. The first peak in the total PDF is resolved as a doublet due to the presence of two distinct bond lengths, In-As and Ga-As. The In differential PDF, which involves only atomic pairs containing In, yields chemical specific information and helps ease the structure data interpretation. Both PDFs have been fit with structure models and the way in that the underlying cubic zinc-blende lattice of In_(0.5)Ga_(0.5)As semiconductor alloy distorts locally to accommodate the distinct In-As and Ga-As bond lengths present has been quantified.Comment: 9 pages, 7 figur
