Multiple choice questions and essay questions in assessment of success rate in medical physiology
...Show More Authors

Background: Assessment is an important part of the learning cascade in education. Students realize it as an influential motivator to direct and guide their learning. The method of assessment determines the way the students reach high levels of learning. It has been documented that one of factor affecting students’ choice of learning approach is the way how assessment is being performed. Many methods of assessment namely multiple choice questions, essay questions and others are mainly used to assess basic science knowledge in undergraduate education. Objectives: The aim of this study is to compare multiple choice questions (MCQ) and essay questions (EQ) (record the success and failure rate of multiple choice questions (MCQ) and essay questions (EQ)) in regards to the Physiology questions. Methods: A retrospective study was done in which the results of the physiology exams -held in the medical college in Baghdad University -in 2010 are recorded. The number of students underwent the exam was 255. A total of 100 essay questions (EQs) and 100 multiple choice questions (MCQs) were evaluated from the written examinations delivered to second year medical students questions belonged to final examination. Results: Regarding essay questions that have been answered, 33.5% of the questions were not answered as a total. 188 students out of 255 had succeeded which represent 73.7% of the students. Out of 78 marks for MCQ, 46.33 had been achieved, and out of 22 marks for essay 12.9 have been achieved. the success in MCQ questions was 82.9% while in the Essay questions was 67.7% and the failure in both types was 12.5%. Out of 100 questions for both MCQ and Essay questions 55.1±7.9 questions were answered for the MCQ and 51.1±15.3 Essay questions were answered. In general the percentage of the succeeded students was 73. 7% and that of failed students was 26.3%. Conclusion: There is no significant difference in the success rate between MCQs and EQs.

Standardized Assessment of Compressive Behavior in Rigid Polyurethane Foams: Influence of Density, Crosslinking, and Aging
...Show More Authors

Rigid polyurethane foams (RPUFs) are essential materials in structural applications due to their thermal insulation, lightweight properties, and mechanical strength. However, evaluating and comparing their compressive performance is complicated by differences in formulation parameters such as density, aging, and crosslink density. This study proposes a standardized normalization approach to evaluate compressive properties across diverse RPUF formulations by adjusting all data to a common reference density. Samples were subjected to controlled aging conditions and analyzed using dynamic mechanical thermal analysis (DMTA) to investigate the relationship between crosslinking behavior and mechanical performance. The results demonstrate

Study of Effect of Diesel Fuel Energy Rate in Duel Fuel on Performance of Compression Ignition Engine
...Show More Authors

The aim of this work is to study the effect of diesel fuel percentage on the combustion processes in compression ignition engine using dual – fuel (diesel and LPG).

 The brake thermal efficiency increased with the increase of diesel fuel rate at low loads, and decreased when load increased. To get sufficient operation in engine fueled with dual fuel, it required sufficient flow rate of diesel fuel, if the engine fueled with insufficient diesel fuel erratic operation with miss fire cycles presented.

Dual-fuel operation at part load showed higher specific fuel consumption than straight diesl operation. At full loads, brake specific fuel consumption of duel fuel engine approaches that for diesel fuel values.

Analysis and Assessment of Essential Toxic Heavy Metals, PH and EC in Ishaqi River and Adjacent Soil
...Show More Authors

This research was conducted to determine content levels of heavy metal pollution. Samples taken from Ishaqi River bank and adjacent agricultural soils area, in ten sites, distributed along 48 km of the Ishaqi River, north Baghdad. The evaluated metals were Zinc, Copper, Manganese, Iron, Cobalt, Nickel, Chromium, Cadmium, Vanadium and Lead. PH and Electric Conductivity (EC) were measured to evaluate the acidity and (EC). Results showed that most site were contaminated with metals evaluated. Among these metals, Zn, Mn, Fe and Ni were consistently higher in all the samples (both river bank and adjacent soil) followed by PB, CU, V, Cd, Co and Cr. The level concentrations of river bank were almost higher than that of adjacent soil. As will be re
