Limitations of rainfall and surface water resources farmers have to use both surface and subsurface resources for growing different crops. In this study optimal management of irrigation water allocation and cropping pattern utilizing conjunctive use of surface and subsurface water resources is studied. Also the effect of reducing water consumption in different growth stages with different irrig...
The present work provides original measurements of the burnout heat flux in saturated ethanol-water mixtures, over the full range of concentrations. These data were obtained at atmospheric pressure on horizontal cylinders, ranging from 0.51 to 2.16 mm in diameter. They reveal significant improvements of the peak heat flux for mixtures, over that which would be expected from pure fluids with the...
In the design of a water supply network, the use of traditional formulas of the peak factor may lead to over-dimensioning the network pipelines, especially in small towns. This discrepancy is probably due to changes in human habits as a consequence of a general improvement of living conditions. Starting from these considerations, and given the availability of a wide random sample data, an analy...
Abstract Lack of stored soil moisture is an essential factor in intensification of the problems of arid and semi-arid areas in Kohgiloyeh va Boyerahmad Province. In these areas, limited surface water and groundwater have rendered vast areas of the region’s fertile lands useless. Despite these problems, appropriate conditions can be provided to plant resistant and adapted species such as olive...
water and nutrient absorption by plants is one of the most conspicuous factors which seriously affect plant productivity. improving physical properties of soilless media and their water retaining capacity can improve plant's nutrient absorption, growth and subsequent yield. in this study, we tried to improve plant nutrient absorption through incorporation of hydrogel into growth media and ...
Silicon (Si) is a beneficial element for on plant growth and development that plays an important role in plant resistance to environmental stresses such as salinity and drought. The present research was conducted to study the effect of Si and water deficit on biochemical, physio-morphological and qualitative traits of cut rose cv. Club-Nika under greenhouse conditions. The factorial experimen...
The studied area in this study is Marand plain with an area equivalent to 517.42 square kilometers in the North West of East Azerbaijan province. In this research, consecutive periods of meteorological and hydrogeological droughts were detected by SWI and SPI drought index at 6 periods (6, 9, 12, 18, 24 and 48 months). For this purpose was used monthly precipitation mean of 7 rain-gauge station...
There is no common understanding of the minimum per capita fresh water requirement for human health and economic and social development. Existing estimates vary between 20 and 4,654 l/c/d, however, these estimates are methodologically problematic as they consider only human consumptive and hygiene needs, or they consider economic needs but not the effects of trade. Reconsidering the components ...
Introduction: Muscular weakness, particularly weakness of lower limb muscles is a symptom of Parkinson disease, which, together with other symptoms, will result in a variety of movement disorders. This research is designed to assess the effectiveness of a water-based exercise program on the lower limb muscles strength of Parkinson patients' knee joints. Materials and Methods: In a semi-exp...
