Background: Kerack is emerging illicit substance which its use is rising up in Iran. It has harmful effects on body organs. The aim of this study is to investigate the effects of Iranian Kerack on sperm parameters and testicular structure of mice. Materials and Methods: In this study, 25 male mice (Balb/C) were divided into five groups (control, sham and three experimental). Experimental groups...

We studied the natural history of Perthes' disease in 62 children in whom the onset of symptoms was in adolescence. Three patterns of disease were noted, namely, late-onset pattern, segmental collapse, or destructive with failure of revascularisation. In the late-onset pattern, the disease followed the sequence of healing seen in younger children, but adequate epiphyseal remodelling did not occ...

the present study was conducted to estimate correlations among performance and egg quality traits in iranian native fowl. data were collected from 21,679 birdsat the isfahan native fowl breeding center to derive genetic parameters for performance traits and egg quality traits were measured on eggs of 1,020 birds. genetic correlations of performance and egg quality traits were estimated with a b...

Degradation of on-field PV modules is inevitable but a normal process; however, it challenging task to explore the causes behind it. Manufacturers and researchers, know degradation, employ both destructive non-destructive procedures. In this study, nine different from three manufacturers have been taken their electrical output data, over several days, has collected. The parameters are compared ...

The diagnosis of cracks in rotating shafts using non-destructive techniques provides a route for avoiding catastrophic failure of these common components. This study measured the dynamic response of a full-scale rotating shaft with three different crack depths. A novel non-destructive system is developed and described. The system uses vertical vibration of the system measured over time and char...

Breast density is more and more considered as an important risk factor for breast cancer and several quantitative breast density evaluation methods have been proposed. The reference material for simulation of the breast attenuation properties of glandular and adipose breast tissues is manufactured by a single provider. In order to characterize the attenuation properties of these materials, meas...

A large amount of oyster mushrooms is wasted every year due to post-harvest losses/decays. An experiment was conducted to observe the effect of low temperature to extend shelf life and nutritional quality of oyster mushroom. The experiment consisted of two treatments including: mushrooms stored at ambient (25 °C) temperature or stored at 3 °C temperature. The experiment wa...

Long-term protection of arid ecosystems changes the vegetation and soil structures. The quantification aboveground biomass carbon content are among principal indicators to evaluate these changes. Most methods used quantify parameters costly, time consuming destructive. In this paper, two non-destructive were compared: digital image processing biometric measurements. Aboveground five perennial s...
