introduction: it has been reported that traumas such as transverse abdominal incision before myocardial ischemia result in a significantly decreased infarct size. this phenomenon is named remote preconditioning of trauma. since small skin burn is one of most common traumas, the effect of this injury on ischemia-induced arrhythmias and infarct size was investigated in a rat model of ischemia-rep...

abstract a sub-sample of lentil (lens culinaris medik. cv. kimia) seeds was kept as bulk (s1) and another sample was separated to large (s2) and small (s3) seeds. a sub-sample of each size was kept as control or high vigor seed lot (a1) and the two other sub-samples were artificially aged for 2 and 4 days (a2 and a3, respectively). field performance and some physiological traits of plants from ...

a total of 448 ross 308 male broiler chickens were assigned to seven treatments with four replicates, each containing 16 chicks. the birds were reared from d 21 to 42 and effects of physical sizes (ad libitum by a basal commercial broiler diet with 3050 kcal/kg me and 19.06% cp/kg from 21 to 42 d. the chickens which received clinoptilolite (1.5% with particle size of 0.4-0.8 mm) showed a signif...

global greenhouse gas emissions from 2000 to 2010 has grown more quickly (2.2%/yr) than in the previous three decades (1.3%/yr). china accounts for approximately 23% of global co2 emissions and the household sector is considered the major contributor. this study conducts a time series analysis of a per person household carbon emissions (hces) in china during 1995 to 2011. annual macroeconomic d...

we apply the two-sector production function developed by ram (1986) to estimate the threshold regression model for iran, concerning the effect of government size on economic growth. three government size indicators are used to find out the different threshold points. the results show a non-linear relationship of the armey curve in iran, in which the threshold effects corresponding to total gove...

in suspension polymerization, particle size distribution of polymer is the outcome of dynamic equilibrium between the break up and coalescence phenomena. the rates of break up and coalescence and consequently polymerization stability depend on several parameters, the most important of which are type and concentration of stabilizer. in this study, the effects of type and concentration of stabili...

the use of acoustic waves in researches related to sea water is of most importance among scientistsrecently. since these waves are the only waves, transmitted in water with lowest attenuation and high speed, they canbe used in many scientific fields. the main goal of this research is to better understand the physics and mechanismsof sound-seabed interaction, including acoustic penetration, prop...

tuberculosis remains as an important socioeconomical and medical problem throughout the world and especially in iran. early and timely diagnosis of pulmonary and extrapulmonary tuberculosis is vital to initiate prompt treatment. current diagnostic methods are either slow or lack enough sensitivity or specificity. several mycobacterial antigens are involved in the complex interaction with the im...
