the treatment of in completely formed pulpless teeth has presented considrable problems. these teeth have wide open apexes and the walls of the root canal diverge toward the apical tissues. mechanical preparation cannot be done in the normal manner beacause of the large initial size and the taper of apical part of the canal , a mechanical stop cannot be produced at the apex of the canal and , t...
the significance of the study of deixis was then mentioned. the purpose of the present study from the outset was to provide a comprehensive overview of all kinds of deixis in persian, describing and defining each in true while considering them structurally and semantically. chapter two consisted of two main parts. a review of the english studies in this respect, besides presenting persian liter...
Herein, the effect of size Mg clusters on graphene nano sheets (GNS) and N‐GNS (C‐ π ) is investigated. The dependence electric conductivities C‐ electrolytes was also explored. This work aims to clarify Mg/C‐ study addition materials their electrical chemical interaction between GNS N‐GNS, respectively. are synthesized by modified Hummers N‐dopant method at room temperature, Characterization e...
in this paper, the non-linear dynamic response of novel steel sandwich panel with hollow i-core subjected to blast loading was studied. special emphasis is placed on the evaluation of midpoint displacements and energy dissipation of the models. several parameters such as boundary conditions, strain rate, mesh dependency and asymmetrical loading are considered in this study. the material and geo...
This paper deals with the determination of the effect of varying material properties on the value of the stress intensity factors, KI and KII, for anisotropic plates containing cracks and subjected to a temperature change. Problems involving cracks and body forces, as well as thermal loads are analysed. The quadratic isoperimetric element formulation is utilized, and SIFs may be directly obtain...
in this article, i compare william faulkner's as i lay dying and sadeq chubak’s the patient stone with respect to the theme of death and from the perspective of existentialism. i argue that despite faulkner’s influence on chubak and similarities in their writings, the iranian modernist novel presents intellectual and aesthetic nuances catering to the domestic material circumstances o...
