exposure to toluene can be associate with genotoxicity, neurological dysfunction, reproductive toxicity, and etc. biomonitoring of hippuric acid (ha) is used for a long time as an occupational exposure index to toluene. the aim of this study was to explore efficiency of ha as a biomarker of exposure to low level of toluene for iranian petroleum depot workers in 2011. personal monitoring to tolu...

The index matrix (IM) is an extension of the ordinary with indexed rows and columns. Over IMs’ standard operations are defined a lot other ones that do not exist in case. Intuitionistic fuzzy IMs (IFIMs) modification IMs, when their elements intuitionistic pairs (IFPs). Extended IFIMs whose indices columns evaluated by IFPs. Different operations, relations operators over IFIMs, some specific on...

on utilizing the spectral representation of selfadjoint operators in hilbert spaces, some error bounds in approximating $n$-time differentiable functions of selfadjoint operators in hilbert spaces via a taylor's type expansion are given.

the effects of agricultural information on the technical knowledge of the greenhouse owners in south khorasan province are dealt with in this study. research a descriptive-correlational methodology was ployed, and in terms of time, it was limited to the activities of the elements of knowledge and agricultural information as obtained from greenhouses during 2009. the study population consisted o...

Level shift operators describe the second order displacement of eigenvalues under perturbation. They play a central role in resonance theory and ergodic theory of open quantum systems at positive temperatures. We exhibit intrinsic properties of level shift operators, properties which stem from the structure of open quantum systems at positive temperatures and which are common to all such system...

Level-one representations of the quantum affine superalgebra Uq[ ̂ gl(N |N)] associated to the appropriate non-standard system of simple roots and q-vertex operators (intertwining operators) associated with the level-one modules are constructed explicitly in terms of free bosonic fields.
