we have two part in this thesis, at first: the interaction of native calf thymus dna (ct-dna) with two anthraquinones including quinizarin (1,4- dihydroxy anthraquinone) and danthron (1,8- dihydroxy anthraquinone) in a mixture of 0.04 m brittone-robinson buffer and 50% of ethanol were studied at physiological ph by uv-vis absorption, florescence, circular dichroism spectroscopic methods, viscos...
this study aims to evaluation of knowledge management processes including knowledge generation & acquisition, saving & organizing, dissemination & sharing and application in the public sector especially in police through a case study based investigation and identifies factors affecting for improvement them. the evaluation was examined through 423 questionnaires provided by in different police u...
An achromatic infrared (lambda = 1.2-4 microm), Si-prism quarter-wave retarder (QWR) is described that uses total internal reflection at a buried Si-SiO2 interface at an angle of incidence phi near 33 degrees, where deltaDelta/deltaphi = 0. The retardance delta deviates from 90 degrees by < +/- 2 degrees within a field of view of +/- 10 degrees (in air) over the entire bandwidth. Because the Si...
In geomorphology there are variety methods to separate and identify the formic units. One of them is Hierarchy Theory. In this paper study area is Gavkhoni Playa. The purpose of this study is to identify separation and display formic units by using GIS and RS techniques hierarchically. To achieve this aims, topographic maps (1:25000, 1:50000), geological map (1:250000), satellite image of senso...
one of the main problems in the quality control of rivers is the high control cost imposed upon pollutant units. the cooperative policy approach in the treatment process between two or more pollutant units is a new and economic perspective in the environmental management of catchment basins. origins of large amounts pollutants which require a high cost to control pollution are trying to start p...
In this paper, the procedure of developing an unconstrained Genetic Algorithm code to solve mooring pattern optimization problems for floating structures is described. How to spread mooring lines around the offshore structures and tension level of these lines are the factors that have direct effect on response or offset of floating units which experience environmental conditions such as waves, ...
