tourism , today as one of the ways to make money, create jobs , and social and political interactions is considered. this paper aims to examine the strengths and weaknesses of tourism development in mahmoud abad ( mazandaran ). the research method in this study is " descriptive - analytical " and to collection of data used field methods such as questionnaires and documentation - library. the sa...
even though, to date, a lot of studies have been conducted on the subject of politeness theory, there are very few studies regarding the applicability of this theory to translation between english and persian which shows the reason behind conducting the present study. this study was carried out with the aim of highlighting whether there is any difference between english and persian methods of u...
Paget disease is a common bone disease characterized by abnormal osteoclasts that are large, multinucleated, and overactive and that contain paramyxovirus-like nuclear inclusions. There is evidence for a major genetic component to Paget disease, with up to 40% of patients having affected first-degree relatives; however, the locus (loci) and gene(s) involved are unknown. Another bone disorder, f...
Terraces are old geomorphic surfaces that are not related to present streams and are best places to study the effect of time on soil formation (chronosequence). This research was carried out to study some physico-chemical parameters especially different forms of iron as soil development indices on terraces of Karaj River in Hassan-Abad, southern Tehran. To determine soil development indices in ...
Objectives: This study aimed to measure non-destructively gold (Au) electrodeposited on a high-gold alloy by modulating coating time and comparing this sputtering Au known thicknesses. Methods: was (plated) 11 plates (A–K) at 2.8V between 20 220 min. Seven strips were sputter coated the same thicknesses (range 50–500 nm). Energy dispersive X-ray spectroscopy (EDS) used minimal electron energy (...
The coordination of the electronic ground states of Fe+ (6D) and FeO+ (6x+) has been investigated in the gas phase with the inorganic molecules H2, HD, D2, H20, CO, NO, N2, 02, C02, N02, and N20. Reaction rate coefficients and product distributions were measured with the Selected-Ion Flow Tube (SIFT) technique operating at 294 f 3 K and a helium buffer-gas pressure of 0.35 f 0.01 Torr. Except w...
Photoionization efficiency curves were measured for gas-phase FeO and CuO using tunable vacuum-ultraviolet radiation at the Advanced Light Source. The molecules are prepared using laser ablation of a metal-oxide powder in a novel high-repetition-rate source and are thermally moderated in a supersonic expansion. These measurements provide the first directly measured ionization energy for CuO, IE...
In the present work copper/diamond composites, such as (Cu-10 Vf % diamond uncoated, Cu-30 Vf % diamond uncoated, Cu-10 Vf % diamond coated NiCrB and Cu-30 Vf % coated NiCrB) as heat sink materials have been fabricated using powder metallurgy and electroless techniques. The copper powder used in this study has been fabricated using electroless technique and the diamond powder was electroless co...
in reality, most structures involved in geotechnical engineering are three dimensional in nature, and although in many, plane strain or axisymmetric approximations are reasonable, there are some, for which 3-d treatment is required. the quantity of data, and the size of the various vectors and matrices involved in such analysis, increase dramatically. this has sever implications for computer r...
This study was conducted to evaluate the modulating efficacy of prolonged oral administration of Foeniculum vulgare Mill. essential oil (FEO) against γ-raysinduced biochemical changes in rats. To achieve the ultimate goal of this study, 32 rats were used, divided into 4 groups. Control group, Irradiated group with a single dose (6.5 Gy), and sacrificed after 7 days of irradiation, group 3 recei...
