the drastic decline of precipitation over the past decade along with overuse of chemical inputs and consequent soil fertility reduction are the most important problems in the approach to agricultural expansion, particularly in urban landscaping. therefore, an experiment was designed to examine the effects of different irrigation levels (40, 70 and 100 % of field capacity, or fc) and different v...

hydrologic evaluation of landfill performance (help) model is one of the most accepted tools to simulate the hydrological attributes of landfills. although some major deviations from real values has been reported about the calculated results for leachate generation by help model but other researchers and/or engineers in practice have used it in some places to estimate amount of leachate produce...

Several silicate materials were plasma sprayed and characterized by the authors in recent years from the point of view of their chemical and phase compositions, microstructure and mechanical as well as thermal properties. Present work is concerned with selected dielectric properties of these deposits. Synthetic mullite and steatite as well as natural olivine-forsterite were plasma sprayed using...

thyme (thymus vulgaris l.) is perennial aromatic shrub belonging to the mint family which has anti-spasmodic, antiseptic, carminative, anti-cough, sputum and antioxidant properties. in order to study the effects of drought stress and bio-fertilizer on plant growth, essential oil yield and constituents of thyme plant, an experiment was conducted in a split plot based on randomized complete block...
