Background and Objective: Water corrosion leads to increase in toxic metals concentration, such as arsenic, copper, lead, cadmium, zinc, nickel, iron and manganese in water. Toxic metals in water consumers cause acute health risks. Scaling water leads to economic and technical problems. Thus, The aim of this study was to investigate the corrosion and scaling potential of wells drinking wate...
abstract drought is the most important factor limiting crop yield word wide. osmotic adjustment (oa) and strong and deep root system result in increased cereal drought tolerance through increasing water uptake and water use efficiency. the impact of root structure and physiological traits on drought stress response was studied in three barley cultivars including yousof (drought tolerant), moroc...
Drought is one of most important factors in desert ecosystems that affect plant growth. In this study some of drought parameters in Calligonumpolygonoideswere studied under control and irrigated conditions in natural condition. Results showed significant differences in water potential between control and irrigated conditions. Proline content in control with the amounts of 3.1 mg /gfw was signif...
Calcium silicate hydrate, or C–S–H, is the chief hydration product of Portland cement. The structure of the C–S–H phase within cement has been proposed and developed via molecular simulations. In such simulations, empirical interatomic potentials for water molecules within C–S–H are adopted to govern the position and relative motion of this key constituent. Initial simulations and force fields ...
In this paper, we describe a very simple experiment with distilled water which could exhibit anomalous potential electrical energy with very minimum preparation energy. While this observed excess energy here is less impressive than [1][2] and the material used is also far less exotic than common LENR-CANR experiments, from the viewpoint of minimum preparation requirement –and therefore less bar...
Extended abstract Introduction: Seed germination is one of the first important and complex stages in the plant life cycle and is affected by many hereditary and environmental factors. Various factors affect germination and seedling establishment. Among these factors are the characteristics of the maternal plant (nutrition, genetics), seed treatment stage at harvest time, as well as environment...

Optimal crop water requirement is needed for precise irrigation scheduling. Prediction of crop water requirements is a basic factor to achieve this goal. In this study, maize potential evapotranspiration (ETp) was prediced by maize simulation model (MSM). Then, it was evaluated and validated using experimental field data obtained in Agricultural Research Station of Shiraz University (Bajghah, F...
