The titled problem of coupled thermoelasticity for porous structure has been solved with an instantaneous heat source acting on a plane area in an unbounded medium. The basic equations of thermoelasticity, after being converted into a one-dimensional form, have been written in the form of a vector-matrix differential equation and solved by the eigenvalue approach for the field variables in the ...

let $(m^{2n},g)$ be a real hypersurface with recurrent shapeoperator and tangent to the structure vector field $xi$ of the sasakian space form$widetilde{m}(c)$. we show that if the shape operator $a$ of $m$ isrecurrent then it is parallel. moreover, we show that $m$is locally a product of two constant $phi-$sectional curvaturespaces.

the researches have made different explanations about rhytons, but they mostly accepted that “rhyton is a kind of a drinking vessel often in the form of an animal, having two holes for pouring water.” rhytons were used in iran from forth millennium b.c. to the end of sasanian period. the animals that are used are of two different kinds: imaginary animals or the real animals. diversity of the sh...

Background: Systematic and purposeful study of self-efficacy beliefs of Iranian nurses in the face of occupational stressors requires understanding the importance of studying this issue and then having a suitable tool to measure it in this group. This study aimed to assess the validity and reliability of the short form of Occupational Coping Self-Efficacy for Nurses Scale (OCSE-N) among Iranian...

an azobenzene bridge was introduced into the lower (or smaller) rim of p-tert-butylcalix[8]arene to form 1,5-singly bridged calix[8]arene derivatives, respectively. bridged calix[8]arene of conformationally rigid wereisolated. the stability of the two structures of bridged calix[8]arenes have been compared.the study of organicstructure to form nanoporous structures is a well known in chemistry ...
