most of the verbal constructions of harzani dialect have got inflectional affixes. the majority of the constructions are made up vy adding a specific verbal affix to the verbal stem (infinitive without infinitive marker). only a few number of them is formed by adding a verbal affix to the past participle of the verb. there are specific rules for the formation of different verbal types. there is...
alumina nanomaterials were synthesized via a solution combustion technique using tris-(acetylacetonato) aluminum(iii) complex (1) and tris-(2-formylphenolate) aluminum(iii) complex (2) at 600, and 1000 °c for 3h. the obtained data showed that the procedure without using fuel resulted in a better phase and morphology. to investigate the phase formation, powder x-ray diffraction technique was use...
The study of wave and its propagation on the water surface is among significant phenomena in designing quay, marine and water structures. Therefore, in order to design structures which are exposed to direct wave forces, it is necessary to study and simulate water surface height and the wave forces on the structures body in different boundary conditions. In this study, the propagation of static ...
In this work, we propose a simple method for obtaining the algebraic solution of a complex interval linear system where coefficient matrix is a complex matrix and the right-hand-side vector is a complex interval vector. We first use a complex interval version of the Doolittle decomposition method and then we restrict the Doolittle's solution, by complex limiting factors, to achieve a complex in...
the purpose of this two-phase, sequential mixed methods study was to find out whether there were any decencies between male and female ma students’ theses regarding the common features of academic writing such as syntactic complexity, means of integrating cited information, and organizing arguments. i chose 10 male written theses and 15 female written theses in tefl and linguistics. in the firs...
Japan and Guilan being located in similar climates have experienced same architectural and artistic characteristics such as Kumiko art and gereh-chini. Due to the fact that so far no research has been conducted on the similarities and differences between Kumiko and gereh-chini, the present research will try to investigate the components forming the two arts. With the aid of comparative studies,...
among the low–dimensional allotropes of carbon, nanotubes and graphene have attracted very much attention from nano–science and nanotechnology specialists. they have been proposed as building blocks in nanometer device engineering. however, these structures are not defect–free. in this thesis, we focused on defective carbon nanotubes and graphene, and studied the effect of couple of very common...
the aim of this study was to determine the effect of motivational self-talk as one of the psychological strategies. motivational self-talk is a type of self-talk that appears to improve performance and control arousal level through increased drive and effort and positive motivation in performance. this study tried to investigate the effect of motivational self-talk on performance of simple and ...
While the role of abiotic factors in governing species interactions is dealt with in various chapters of this book (e.g. Chap. 7 by Terlizzi and Schiel, Chap. 9 by Benedetti-Cecchi and Chap. 13 by Gili and Petraitis), we will focus here on the biotic factors that affect species interactions. Due to the large number of examples on biotic interactions, we can not and do not attempt to give a comp...
boron nitride semiconducting zigzag swcnt, $b_{cb}$$n_{cn}$$c_{1-cb-cn}$, as a potential candidate for making nanoelectronic devices was examined. in contrast to the previous dft calculations, wherein just one boron and nitrogen doping configuration have been considered, here for the average over all possible configurations, density of states (dos) was calculated in terms of boron and nitrogen ...
