INTRODUCTION Preanalytical errors, along the process from the beginning of test requests to the admissions of the specimens to the laboratory, cause the rejection of samples. The aim of this study was to better explain the reasons of rejected samples, regarding to their rates in certain test groups in our laboratory. MATERIALS AND METHODS This preliminary(More)
The effect of the constant and variable thermal conductivity on the temperature distribution for different materials had been carried out. A uniform heat generation was supplied to each of the selected materials. Three materials were chosen for this study (Copper, Aluminum and Iron). Analytical solution with MATLAB programming had been accomplished for the(More)

In this study, the direct impact test for wheelchairs was modeled and analyzed. The strength of the wheelchairs frame was analyzed using LS-DYNA computer code. Two frames of commercially used wheelchairs were modeled and analyzed under direct impact conditions. The stresses and deformed shapes for the loaded frames were obtained , compared and their(More)
