Planting Haloxylon aphyllum under oil mulches has frequently been used for stabilizing mobile sands in Iran for during the last three decades. This study is carried out in stabilized sandy desert of Samad Abad-e-Sarakhs to evaluate the implications of planting Haloxylon aphyllum on the vegetation and soil attributes. Sampling was carried out random-systematically in the representative areas of ...

Shortage of irrigation water is a major problem constraining in agricultural production in arid and semi-arid regions. Deficit irrigation is one way to cope with water scarcity and increase water use efficiency. Determining the optimum applied water based on economic analysis is a major key to the deficit irrigation strategy. In this study, the required equations were derived to determine the o...

Porous silicon (PS) samples are obtained by electrochemical anodization of Si wafers in HF+DMF solution. The hydrogen complex components are formed on the inner surface walls of porous silicon. In this work the depth profile of porous silicon is estimated by measurement of hydrogen content in the depth of the sample. Since the well-known ion beam analysis simulation programs are inappropriate f...
