Energy generated by the force of water in hydropower can provide a more sustainable, non-polluting alternative to fossil fuels, along with other renewable sources of energy, such as wind, solar and tidal power, bio energy and geothermal energy. Small scale hydroelectricity in Iran is well suited for “off-grid” rural electricity applications, while other renewable energy sources, such as wind, s...

MOTIVATION Secondary structure underpins the folding pattern and architecture of most proteins. Accurate assignment of the secondary structure elements is therefore an important problem. Although many approximate solutions of the secondary structure assignment problem exist, the statement of the problem has resisted a consistent and mathematically rigorous definition. A variety of comparative s...

Abstract Flow prediction is regarded as a major computational process in strategic water resources planning. Prediction’s lead time has an inverse relationship with results’ accuracy and certainty. This research studies the impact of climate-atmospheric indices on surface runoff predictions long time. To this end, correlation 36 long-distance climate was examined at 10 key nodes Great Karun mul...

There is a strong mutuality between tourism and environment via the creation of feedback mechanisms, since tourism often places adverse effects upon the quality and quantity of natural and cultural resources of the destination, leading to its qualitative and quantitative degradation. Within theEnvironmental Impacts Assessment (EIA) studies, various methods have been proposed to assess and analy...

Drought is the most significant constraint for crop production in arid and semi-arid regions. In order to assess drought tolerance in fifteen rapeseed (Brassica napus) cultivars using yield-based drought tolerance indices, two experiments were conducted at the research station of College of Agriculture, Shiraz University, Shiraz, Iran during 2009-2010 growing season. The cultivars were...

Widely consumed type of rice in the world with white pericarp and is known as non-pigmented rice. Recently, pigmented traditional varieties have become popular among consumers due to its dark having nutritional value. This variety important determining digestibility starch Glycemic index (GI). The depends on properties starch, including crystallinity amylose: amylopectin ratio. Hence, study foc...
