In the present study, a simple-to-use method is proposed for preliminary prediction of occurrence shallow landslides (generally, with thickness 1–2 m) due to rainfall. This can be used when water table forms within slope or existing groundwater level rises rain infiltration, resulting in an increase pore pressure. A relationship also provided establish these conditions occur and consequently us...
Rapid development and population growth have resulted in an ever-increasing level of water pollution in Malaysia. Therefore, this study was conducted to assess water quality of Selangor River in Malaysia. The data collected under the river water quality monitoring program by the Department of environment from 2005 to 2015 were used for statistical analyses. The local water quality indices were ...
abstract: the potato tuberworm, phthorimaea operculella (zeller), is an important insect pest of potato (solanum tuberosum l.) in the storage and field in most parts of the world especially in tropical and subtropical regions due to its close relationship with the host, high reproductive potential and high economic losses. information on host preference, life table parameters and digestive en...
asymmetric polyethersulfone (pes) microfiltration flat sheet membranes were composed by the phase inversion method (pim) and were used as supports. composite membranes were fabricated by coating silicone rubber as selective layer. effect of different concentrations of pes and pdms and different solvent such as nmp, dmf and dms effects as pes solvents and support thickness and different coagulat...
abstract over the past two decades, applied linguists and language teachers have shown a great deal of interest in genre-centered approaches , mainly because of pedagogic concerns . this has been due to the need to help non-native readers enhance their ability to understand academic and scientific texts. following swales’ (1981) works on genre analysis, studies of different sections of resear...
Food products account for a significant amount of the Iranian imports. Despite the rising prices of food products over the last two decades, their imports have been increasing too. In this study import demand of the main imported food products is empirically analyzed using Quadratic AIDS. Welfare impacts are measured using compensated variation. The results indicate that all products, except te...
introduction: given its low and sparse precipitation both in spatial and temporal scales, iran is nestled in an arid and semiarid part of the world. on the other hand, because of population growth, urbanization and the development of agriculture and industry sector is frequently encountered with increasing water demand. the increasing trend of water demand will widen the gap between water suppl...
due to increasing demand for the scarce available water throughout the world it is an extremely important matter, in water management, to make serious attempts in determining its true economic value. this paper discusses the optimal allocation of water to agriculture, the relatively true economic value of water as well as the cropping patterns for the shirvan barzo (sb) dam area in north kh...
This paper examines the relationship between domestic water sources, demand and associated problems in the context of a rapidly increasing household population in Nassarawa Eggon town, Nasarawa State, Nigeria. The data for this research were generated using a questionnaire survey of systematically selected households, and analysed using descriptive statistics in the form of frequencies and perc...
Rising demand for food, fiber, and biofuels drives expanding irrigation withdrawals from surface water and groundwater. Irrigation efficiency and water savings have become watchwords in response to climate-induced hydrological variability, increasing freshwater demand for other uses including ecosystem water needs, and low economic productivity of irrigation compared to most other uses. We iden...
