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...
One of the undesirable features in pistachio nuts (Pistacia vera L.) is the incidence of non-split nuts, which affects the price of the final product. In order to attain the kernel inside, the non-split nuts are mostly cracked mechanically. However, this practice may damage the kernel. Akbari variety of pistachio nut was selected to evaluate the influence of different non-mechanical treatments ...
in reality, most structures involved in geotechnical engineering are three dimensional in nature, and although in many, plane strain or axisymmetric approximations are reasonable, there are some, for which 3-d treatment is required. the quantity of data, and the size of the various vectors and matrices involved in such analysis, increase dramatically. this has sever implications for computer r...
nowadays in trade and economic issues, prediction is proposed as the most important branch of science. existence of effective variables, caused various sectors of the economic and business executives to prefer having mechanisms which can be used in their decisions. in recent years, several advances have led to various challenges in the science of forecasting. economical managers in various fi...
introduction: cholestasis is impairment of normal bile excretion into the duodenum and classified as mechanical and non mechanical cholestasis. mechanical cholestasis presents with increase in bile duct diameter or obstruction in bile duct in an ercp. cholestasis leads to different complications. one of these complications is mucosal peptic erosion leading to gastrointestinal bleeding, perforat...
abstract objectives gradual increase length and complexity of utterance (gilcu) therapy method is a form of operant conditioning. this type of treatment is very precise and controlled that is done in 54 steps in 3 speech situations consisted of monologue, reading and conversation. this study aimed to examine the effects of gilcu treatment method on reduction of speech dysfluency of school-age...

One of these complications is mucosal peptic erosion leading to gastrointestinal bleeding, perfora...
for several years, researchers in familiarity of efl teachers with post-method and its role in second and foreign language learners’ productions have pointed out that the opportunity to plan for a task generally develops language learners’ development (ellis, 2005). it is important to mention that the critical varies in language teaching was shown is the disappearances of the concept of method ...
Background and purpose: In the last months of 2019, the new coronavirus infection (COVID-19) spread worldwide. This study investigated the need for mechanical ventilation in children who were admitted for COVID-19. Materials and methods: This article provides a systematic review of studies about children with COVID-19 requiring invasive or non-invasive mechanical ventilation. Electronic databa...
