The theoretical-empirical technique of hydrocarbons prediction in wells sections. New aspects

the relationship between learners critical thinking ability and their performance in the reading sections of the tofel and ielts test

the study reflected in this thesis aims at finding out relationships between critical thinking (ct), and the reading sections of tofel and ielts tests. the study tries to find any relationships between the ct ability of students and their performance on reading tests of tofel and academic ielts. however, no research has ever been conducted to investigate the relationship between ct and the read...

Prediction of Temperature Profile in Oil Wells

A mathematical model has been developed to predict the temperature distribution in wellbores either offshore or inshore. It is incorporated the different activities encountered during drilling operations. Furthermore, the effect of drill collar and casings and bit rotating in a well during completion has been considered. The two dimensional approach is presented in the form of a computer progra...

Social Dumping: Theoretical and Empirical Aspects

Favorable outcomes of using critical appraisal technique beside lecturing method for teaching theoretical sections

Introduction: We aimed to assess the outcomes of critical appraisal method beside lecturing versus lecturing method regarding theoretical sections among the student of msc of nutritional science. methods: This semi-experimental study was undertaken on 8 students of nutritional science in two semesters during 2009-2010. Some sections were taught via using critique of original articles, but oth...

prediction of ignition delay period in d.i diesel engines

a semi-empirical mathematical model for predicting physical part of ignition delay period in the combustion of direct - injection diesel engines with swirl is developed . this model based on a single droplet evaporation model . the governing equations , namely , equations of droplet motion , heat and mass transfer were solved simultaneously using a rung-kutta step by step unmerical method . the...
