a number of researches have been performed in the field of elemental analysis of fruitsfrom different areas of iran and there is a vast unstudied area in this field. in this study, seven mineral elements such as na, k, ca, mg, fe, zn and cu in the tree soil, citrus limunum juice of gorgan and iranshahr gardens and citrus limetta juice of gorgan and bandarabas gardens were determined by flame ph...

An investigation into the effect of countersunk depth, plate thickness, countersunk angle and plate width on the stress concentration around countersunk hole is carried out with the help of finite element analysis. The variation of stress concentration with respect to these parameters is studied for three types of loading viz. uniformly distributed load, uniformly varying load and functionally ...

Objective: In patients with a history of suicidal depression, recurrence of depressive symptoms can easily reactivate suicidal thinking. This study investigated whether training in mindfulness, which is aimed at helping patients “decenter” from negative thinking, may help to weaken the link between depressive symptoms and suicidal cognitions.

mercury is a dangerous and an extremely toxic element, which can transfer to the food chain.presence of this element in the atmosphere particularly during the rainy seasons cause soil and environmental pollution, therefore this research will evaluate the transformation of mercury vapor from the atmosphere through precipitation into the soil. in the present study, mercury concentrations were det...

Selenium (Se) is a trace element extremely important for proper development and growth of the organism. The concentration of Se in blood components of women in early stages of pregnancy varies widely from one country to another and depends, largely, on the amount of daily dietary selenium intake. Se intake of 1 μg/kg body weight, i.e., 60 μg-70 μg per day, is recommended for adults. Dietary Se ...
