introduction spatial studies as the main tools for the detailed study of all tangible and intangible aspects of regions have special ranks among all kinds of planning. the conformity of this organization with physical environment forms the spatial structure of which is usually observed as a distributed and isotropic spatial structure, focus and polar, unbalanced and haphazard, random and balanc...
in this paper, absorption spectra of both solution and films of cyano azobenzene polymer are investigated. the analysis of overlapped absorption spectra of polymer, related to trans and cis isomers, shows that the population of cis isomers is higher than trans isomers. it means that, cyano azobenzene molecules have a folded structure in polymer, in thermal equilibrium. presence of cyano molecul...
The population structure of Aphanius anatoliae in Lake Eğirdir-Isparta-Turkey was studied, using 522 fish monthly in 2008. This study were observed in the number of individuals of each sex, age, weight and size compositions. In addition, the total length-weight relationship was calculated as well as the Von Bertalanffy growth equation. A study of the food uptake throughout the year has been ca...
