All organisms are probably exposed to different types of electromagnetic fields (EMFs). This study is an attempt to evaluate the effect of extremely low-frequency EMFs (50 Hz) on some growth parameters and survival rate of common carp fingerling. The fry (n = 120, averaged 16.76 ± 0.88 g in initial weight) was exposed to ELF-EMF at four intensities of 0.1, 0.5, 1 and 2 mT only once for 2 h and ...

BACKGROUND Research results from large, national population-based studies investigating gender differences in weight dissatisfaction and disordered eating across the adult life span are still limited. Gender is a significant factor in relation to weight dissatisfaction and disordered eating. However, the reasons for gender differences in these conditions are still poorly understood. The aim of ...

background: sparganosis is caused by the invasion of spirometra sparganum into various tissues/organs. subcutaneous sparganosis can be diagnosed by biopsy , while visceral/cerebral sparganosis is not easy to be diagnosed. the diagnosis de-pends largely on the detection of specific anti-sparganum antibodies. t he specific-ity of the elisa could be increased by using s. mansoni sparganum excretor...

Combining ability effects were estimated for different agronomic characters in line × tester crossing program comprising 21 hybrids produced by crossing 7 lines and 3 testers. Parents and hybrids differed significantly for general combining ability (GCA) and specific combining ability (SCA) effects, respectively. The variance due to GCA and SCA showed that gene action was predominantly additive...

morphophysiological variations of field bindweed populations in tehran province was studied during 2006 and 2007 growing seasons using multivariate analysis methods. to determine the variations, 43 morphological and physiological characters were considered biometrically.  the main characters at principal component analysis (pca) consisted of leaf dry weight, shoot dry weight, and leaf area to i...
