a valid questionnaire is a precursor to a sound measurement process. this study examined the psychometric properties of the persian version of the revised competitive state anxiety inventory – 2 (csai-2r). a total of 131 female taekwondo athletes (mean age =12.37 ± 2.52) from damghan completed csai-2r at competition venues. confirmatory factor analysis was used to analyze the structure of csai-...

among state`s duties are constructing roads, water pipelines and the likes. in order to do these the state sometimes has to utilize private owners` lands. this research, we seek to investigate this questions that is there any possibility of liability for usurpation for state if these formalities are not be observed? some researchers have questioned the possibility of this liability. in this res...

an enhanced displacement feedback structural control procedure is presented for performance-based design in this paper. at first, a comparative study is implemented assessing three most common active control algorithms including state, acceleration, and displacement feedback controls. the advantage of the displacement feedback algorithm for active control of structures against earthquakes is de...

hemoglobin is a porphyrin containing protein with an a2b2 tetrameric structure and like other porphyrin compounds shows spectral behavior of species specific characteristics. researchers tend to relate bands in the hemoglobin spectra to certain structural and/or functional features. given the fact that hemoglobin is the main oxygen carrier in animals functioning through the oxy«deoxy equilibriu...

in this research, a semi empirical approach has been suggested for calculating the activation energyof unimolecular thermal decomposition of vinyl ethers yielding saturated products. the calculationprocedure is based on the use of molecular mechanics (mm) methods. these methods which involvethe construction of the transition state for a molecule mainly consider the formation of a “hydrogenbridg...
