some of arid regions problems of iran are saline and sodic soils. in improvement and reclamation of iranian arid rangelands, some foreign species of atriplex had been imported and adapted for many years ago. the most adapted species was atriplex canescens. at the present research, some environmental factors, vegetative characteristics (na, ca, mg and k), soil properties (moisture, ec, ph, solut...

Plant diversity and vegetation distribution in an area are related to the soil physical and chemical properties. The knowledge of relationships between species diversityand soil parameteris essential for sustainable ecosystem management. This study was conducted to investigate the relationships between soil factors and species diversity indices in the protected rangelands of Lashgardar, Malayer...

Texture image analysis is one of the most important working realms of image processing in medical sciences and industry. Up to present, different approaches have been proposed for segmentation of texture images. In this paper, we offered unsupervised texture image segmentation based on Markov Random Field (MRF) model. First, we used Gabor filter with different parameters’ (frequency, orientatio...

Itai and Rodeh [IR] have proved thal for any 2-conncctcd graph G and any vertex S E G there are two spanning trees such that the paths from any othcr vcrtex to s on the trees are disjoint. In this p,aper the result is generalized to 3-connected graphs. T ec hn io n C om pu te r Sc ie nc e D ep ar tm en t T eh ni ca l R ep or t C S0 46 2 19 87 -1

ripening is one of the most important stages in production of cheese. in this research to comprehensive study of uf cheese ripening as the major industrial cheese that is produced in iran, mass transfer, heat transfer and changes in quality and sensory properties, simultaneously considered and a mathematical model was developed to describe them. thus, at first, lipolysis, proteolysis, texture a...
