one of the purposes of ecotourism is to relax and aspirate the natural energy. sacred and energetic sites are the locations for experiencing the relaxation. since 2005 the ecotourism for aspirating the natural energy or spiritual ecotourism has been developed in iran. there are some places in iran which have a kind of energy as subtle energy for increasing personal health and awareness. these p...

Novel method doped carbon with nanoparticle Cr2O3 and thin film has been studied in much thought in wavelength range, the doping can help new excellent physical and chemical properties for carbon, this application has a semiconductor feature. Nanocomposite thin film deposited on copper and glass substrates have been created by utilizing Spray Pyrolysis method. The prec...

low nutritive value and suitability of barley as a feedstuff for broilers is mainly due to its non-starch polysaccharides. an experiment was carried out to evaluate if diets high in barley alter the mechanisms responsible for the absorption of nutrients across the intestinal epithelium of broilers, using d-xylose absorption test. thirty, 14-d old male broiler chicks (ross 308) with similar body...

Abstract Concrete-filled steel tube columns are widely used in civil engineering structures due to their excellent ductility, energy absorption capacity, ultimate load-bearing and seismic behavior. In this paper, a numerical study modeling of eight lightweight concrete conventional filled tubes was carried out using ABAQUS software, the lateral load-carrying capacity square circular under cycli...

This article presents the method of extraction-preconcentration of Lead, Cadmium, and Nickel ions from food samples using the Ghezeljeh montmorillonite nanoclay (Geleh-Sar-Shoor) as a new native adsorbent in batch single component systems. The extraction-preconcentration of heavy metals were carried out by applying the solid phase extraction (SPE) method followed by atomic abs...

thin films of binary bi 0 -teo and bi 0 -v 0 systems were prepared by the thermal co-evaporation technique in a vacuum at room temperature. the optical absorption edge of these systems are studied in the wavelength of 200-800 nm using a perkin-elmer uv/vis spectrophotometer. it is found that the value of n=3/2 in the davis-mott equation is best fitted for the fundamental absorption edge for the...

The objective of this experiment was to determine the respective effects of level of intake and of the amount of volatile fatty acids (VFAs) present in the rumen on VFA ruminal absorption. In a factorial design, six ewes received a hay diet either at 126 or at 73% of energy maintenance requirements. Their capacity of absorption of VFAs was evaluated by the method of temporarily isolated rumens,...
