Barley crop grown in semiarid areas may experience water deficit especially during grain filling that makes them more dependent on stem water-soluble carbohydrates (WSC). Fructans are the most important reserved carbohydrates. A pot experiment was undertaken at Shahid Chamran university in the duration of 2010-2011 growing seasons to investigate the accumulation and loss of WSC and the activity...

The data collected primarily through a 31-item questionnaire with four scales ranging from "not important" "very important." responses analyzed determine amount DI awareness ...

terminal heat stress is the most widespread heat stress in the world. in order to evaluate the effect of heat stress on yield, yield component, and mopho-phenological traits of barley, 10 barley genotypes including the 2-row genotypes: mahour, khoram, nimrooz, abidar and 6-row genotypes: yousef, rihan 03, izeh, zahak, nosrat, jonoub were tested under normal (optimum sowing date) and heat stress...

Parkinson's disease (PD) is caused by degeneration of A potential autologous dopamine source that has re-neuromelanin-containing dopaminergic (DA) neurons in ceived little attention until recently is the c...

For more than a century, vertebrate taste buds have been singled out as the prime example of neural induction of sensory organs during development. This view has held that late in embryogenesis, sensory nerve fibers contacted the oral and pharyngeal epithelia, and induced a subset of epithelial cells to give rise to multicellular taste buds (Guth, 1957; Hosley et al., 1987; Torrey, 1940). The i...

the awareness of administrative organization of rescue and relief operation from spatial and temporal dimensions is pre requirement of rescue and relief. this subject and existence of accessible transportation networks that can save their performance after emergency situations are the most important parameters in efficiency of rescue and relief operation. the position of firefighting stations a...
