in this study the effect of salt stress on banding patterns of superoxide dismutase (sod), catalase (cat) and peroxidase (pox) in 18 genotypes of white common bean (phaseolus vulgaris l.) were examined under two levels of nacl )0 and 400 mm) stress. for each isozymic band the “density × area” scores on gels were evaluated by mcid software and considered as enzymatic activity. three isozymes wer...

introduction: gestational stress can lead to cerebral functional disorders, such as epilepsy, probably due to the disturbance in the cerebral maturation and causing abnormal neuronal correlations. in the present study, effect of gestational predator stress on the neonatal epileptic behaviors was investigated in rats. methods: female rats (200 ± 20 g) were divided into two groups intact pregnant...

net photosynthesis rate (pn), stomatal conductance (gs) and transpiration rate (e) of anise hyssop were measured during the four cloudless days, in reference to diurnal fluctuations of leaf temperature (tleaf), leaf vapor pressure deficit (vpd leaf) and photosynthetic photon flux density (ppfd) in well watered (ww), stressed (s) and recovered (r) plants. an analysis of measured data showed that...

Preplanning or look ahead is one of the basic principles of the current model of Danish intonation. The frequency range spanned by a prosodic phrase is constant regardless of phrase length, ceteris paribus, and the frequency step size between one stressed syllable and the next varies inversely with the number of stressed syllables in the phrase. This empirically well-founded fact is based on re...
