because of the presence of special properties in semi arid catchment, these areas are suitable for drought events. the responses of these areas to drought events are in the form of the disappearance of plant cover on surfaces slopes, intensive erosion or landslide occurrence on side of rivers’ course. azarshahr catchment (situated in 37ëš 36′ to 37ëš 49′ n and 44ëš 20′ to 45ëš 49′ e) ...

Almond oil is used in many cosmetic products as a snack, in confectionery (marzipan, "turrón", nougat), food products (almond milk, ice cream, chocolate), culinary recipes and also cosmetic base. For surveying the effects of almond genotype and growing location on oil percentage of oil seed content and fatty acid of almond, seeds of 6 almond cultivars: Ferragnes, Tuono, Azar, Sahand, Nonpareil ...

Due to the decreasing trend of rangelands, many native species are vulnerable and even at risk of extinction. Therefore, seed preservation and propagation of native species of rangelands and recognition of the characteristics of grazing, drought tolerance and their production potential are very beneficial. In this study, the five species of Festuca ovina, Festuca rubra, Br...

To the Editor: Purkinje cells constitute the sole output of the cerebellar cortex. They play pivotal roles in maintaining balance and regulating movement by modulating the firing response of the deep cerebellar nuclei. Electrophysiological dysfunction of Purkinje cells brings about cerebellar ataxia. Accordingly, rescue of Purkinje cells could have important therapeutic implications. In spite o...

measuring the perceived quality of residential environments is one of the fields of inquiry for housing environment researches. most of the data on the perceived quality of residential environments are restricted to existing and large cities experiences. however, little attention has been paid to new town residential complexes particularly in third world countries. residential and neighborhood ...

summarythe explanation of the elastic, or velocity structure of the earth has long been a goal of the world’s seismologists. for the first few decades of seismological research, the investigation on velocity structure was restricted to the determination of one-dimensional models of the solid earth and of various regions within it. seismologists are currently obtaining three dimensional velocity...

We analyze a class of estimators based on convex relaxation for solving high-dimensional matrix decomposition problems. The observations are noisy realizations of a linear transformation X of the sum of an (approximately) low rank matrix with a second matrix endowed with a complementary form of low-dimensional structure; this set-up includes many statistical models of interest, including factor...

in this study, the quaternary deformation and tectonic activity of saeedabad-chai drainage basin, are assessed using geomorphic approach. this drainage basin is located in northern slope of sahand mountain. north tabriz fault (ntf), is passing from the saeedabad-chai basin. variation in the morphology of mountain front provied the basis for geomorphic assessment of tectonic activity. therefore,...

in semi arid area geomorphological impacts of dams are very major. dams, as man- made structures, have major impacts on river hydrology, primarly through in the timing, magnitude, and frequency of low and high flows, ultimately producing a hydrologic regime differing significantly from the pre-impoundment natural flow regime. despite the profiles of dams on river regulation for water resources ...
