in saturated soils, heating induces thermal expansion of both grains and the pore fluid. lower thermal expansion coefficient of aggregates results in the increase of pore pressure and reduction of the effective stress besides subsequent volume changes due to the dissipation of pore pressure and heat transfer. dissipation of thermally induced pore pressure with time is a coupled thermo-hydro-mec...
abstract: advertisements are the most accessible type of authentic materials, and this is one reason why they are used more and more in english teaching classes. for this cause, studies in the field of advertisements are very widespread nowadays. for pun is one aspect which makes advertisements more interesting, it is used more than before in advertisements. use of puns makes an advertisement m...

conclusions garlic powder consumption can reduce blood pressure, yet in this model, it did not have an effect on the interaction between renin angiotensin system and nitric oxide inhibition. results at the beginning and at the end of experiments, systolic blood pressure was higher in the hypertensive groups than the normotensive group. however, at the end of the study, diastolic blood pressure ...
this study attempted to explore if teaching english collocations through two different modes of awareness-raising and input flooding has any possible differential effect on immediate retention as well as retention in a delayed assessment. it also compared the possible differential effect of teaching english collocations implicitly and explicitly on actively using the items in writing. m...
Identifying factors which contribute to young adults’ temptation for substance use is a significant step toward prevention of this social harm. The current study aimed to examine the role of a set of personal and social factors and their interaction in shaping temptation for cigarette smoking and substance use among university students. Participants were 766 students at Shahid Beheshti Univers...
Die corner filling is very important in tube hydroforming process. Definition of the internal pressure path is a key factor in improving the corner filling. However, the factors that cause improvement of corner filling are still unclear. In this paper, effect of bilinear pressure path on corner filling in hydroforming of tube in box-shape die is studied using both finite element simulation and...
Aims: The present study was conducted with the aim of determining the effect of passive movements on hemodynamic parameters, including systolic blood pressure, diastolic blood pressure, mean arterial pressure, pulse, and pulse pressure of patients under ventilation. Materials & Method: In this controlled clinical trial, 64 patients under ventilation in Kohgiluyeh and Boyer-Ahmad University of ...
this study was carried out to indicate the effects of olive leaves on arterial blood pressure, blood lipids and growth performance in broiler chickens. experiment was conducted with 5 treatments and 4 replicates with 25 birds per each replicate in a completely randomized design with over all 500 male arian strain 1-day old broilers. the period of study was 42 d. treatments were control, drug of...
This paper investigates the effect of micropile installation into saturated sandy soil by means of finite element method. The obtained results from numerical modeling are compared with the received data from the site. The validation of software has been done by simulating standard penetration test. The effect of some changes in spacing (3m, 1.6m and 0.8m) and injection pressure (1cm, 2.5cm, 5cm...
