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...
background & aim : despite the well evidenced health benefits of regular physical activity, many iranian college students do not engage in physical activity sufficiently. the aim of this study was to assess cognitive factors related to regular physical activity in college students in hormozgan university of medical sciences, bandar abbass, iran. methods & materials : a total of 314 students fro...
in this study, the effects of oleothermal modification on physical and mechanical peroperties of fir wood (abeis sp.) blocks were examined. at first, some blocks of fir wood with 5 × 20 × 120 cm dimensions were prepared. the blocks were treated in soybean oil. the effects of 3 factors such as treatments temperature (180and 200 °c), holding time (12 and 15 h) and initial moisture content of wood...
conclusions given the importance of physical activity, and given that most women are at the pre-contemplation stage of the trans theoretical model, it seems necessary to devise educational interventional plans for the promotion of physical activities among women referred to health centers. patients and methods this was a cross-sectional study with 310 randomly selected females referred to healt...
abstract the purpose of this study is twofold: on the one hand, it is intended to see what kind of noticing-the –gap activity (teacher generated vs. learner generated) is more efficient in teaching l2 grammar in classroom language learning. on the other hand, it is an attempt to determine which approach of the noticing-the-gap- activity is more effective in the long- term retention of grammar...
background: because of the sedentary lifestyle and decreasing mobility and physical activity of the modern man, non-contagious diseases are rising. nurses and emergency medical personnel are of the individuals who due to their stressful jobs and intensive shift work do not have enough physical activity. the aim of this study was to determine the factors related to regular physical activity amon...
today, scouring is one of the important topics in the river and coastal engineering so that the most destruction in the bridges is occurred due to this phenomenon. whereas the bridges are assumed as the most important connecting structures in the communications roads in the country and their importance is doubled while floodwater, thus exact design and maintenance thereof is very crucial. f...
