seismic retrofit strategies have been developed in the past few decades following the introduction of new seismic provisions and the availability of advanced materials and methods. it can be observed that new approaches to deal with more lateral forces are more innovative and more energy absorbent. in line with this, there is a growing trend toward the use of steel shear walls as a system with ...
The present study was carried out to evaluate the effect of abscisic acid (ABA) and chlorocholine chloride (CCC) on growth, nodulation and changes in endogenous level of plant hormones indole acetic acid (IAA) and Gibberellic acid (GA) of mung bean grown under normal or water stress conditions. Two varieties (cv.NM 98 and cv.HCM 209) of mung bean were soaked in 10 M ABA or in chlorocholine chlo...
Drought is a limiting factor for N(2) fixation in soybean [Glycine max (L.) Merr.] thereby resulting in reduced biomass accumulation and yield. Drought-sensitive genotypes accumulate ureides, a product of N(2) fixation, during drought stress; however, drought-tolerant genotypes have lower shoot ureide concentrations, which appear to alleviate drought stress on N(2) fixation. A key enzyme involv...
cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
In studying indigenous climate knowledge, two approaches can be envisioned. In the first, traditional knowledge is a cultural built-in object; conceived as a whole, its relevance can be assessed by referring to other cultural, economic, or technical components at work within an indigenous society. In the second, the accuracy of indigenous climate knowledge is assessed with western science knowl...
In recent years due to increase of drought frequency, lakes water levels, in arid and semi-arid regions of the Iran, have dropped significantly. Therefore, in addition to ecosystem degradations, drought challenges socio-economic sectors as well. The purpose of this study was to evaluate the water level fluctuations of Parishan Lake during the wet and dry periods, and the impact of drought indic...
This paper analyses the transition of water rights institutions in Victoria, Australia, between 1840 and 1886. It will focus on the shift from the common law doctrine of riparian rights to government control of water supplies via quasi-government organisations known as irrigation trusts examining factors leading to this transition and whether it increased institutional efficiency. Evidence sugg...
Overexploitation of groundwater resource may result in lowering groundwater table at a faster rate due to an imbalance in the total recharge and total withdrawal. In order to make a balance between groundwater exploitation and recharge, the major remedial measures suggested are to strengthen groundwater management, adopt water demand policies, raise water use efficiency, and to increase water s...
Non-irrigated crops in temperate climates and irrigated crops in arid climates are subjected to continuous cycles of water stress and re-watering. Thus, fast and efficient recovery from water stress may be among the key determinants of plant drought adaptation. The present study was designed to comparatively analyze the roles of drought resistance and drought recovery in drought adaptation and ...
in rural areas, where water tends to be traded less and is mostly used as an essential farm input, water users association can be as an alternative for water resource management. the purpose of this study was to investigate influence factors on the farmers’ tend to constitute water users associations. research population was all farmers covered of feyzabad irrigation network supply (192 farmers...
