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...

1. introduction wetlands are unique ecosystems that often appear on the sidelines of aquatic or terrestrial systems. they are among the most productive ecosystems on earth, the loss of which can lead to disastrous effects on the wild life and biodiversity. scientists believe that the destruction of wetlands results in the extinction of native species and their specific habitat. as the livelihoo...

We consider a BMN operator with one scalar, φ and one vector, DμZ, impurity field and compute the anomalous dimension both at planar and torus levels. This mixed operator corresponds to a string state with two creation operators which belong to different SO(4) sectors of the background. The anomalous dimension at both levels is found to be the same as the scalar impurity BMN operator. At planar...

For suitable Banach spaces $X$ and $Y$ with Schauder decompositions and‎ ‎a suitable closed subspace $mathcal{M}$ of some compact operator space from $X$ to $Y$‎, ‎it is shown that the strong Banach-Saks-ness of all evaluation‎ ‎operators on ${mathcal M}$ is a sufficient condition for the weak‎ ‎Banach-Saks property of ${mathcal M}$, where for each $xin X$ and $y^*in‎ ‎Y^*$‎, ‎the evaluation op...

Let  $varpi$ be a representation of the homogeneous space $G/H$, where $G$ be a locally compact group and  $H$ be a compact subgroup of $G$. For  an admissible wavelet $zeta$ for $varpi$  and $psi in L^p(G/H), 1leq p <infty$, we determine a class of bounded  compact operators  which are related to continuous wavelet transforms on homogeneous spaces and they are called localization operators.

In this paper, we investigate the multiple attribute decisionmaking (MADM) problems with 2-tuple intuitionistic fuzzylinguistic information. Then, we utilize arithmetic and geometricoperations to develop some 2-tuple intuitionistic fuzzy linguisticaggregation operators. The prominent characteristic of theseproposed operators are studied. Then, we have utilized theseoperators to develop some app...

With the aid of the creation operators introduced in our previous works, we show how to construct a basis of the space of quasi-local operators for the homogeneous XXZ chain.

Eigenstates of the linear combinations a 2 + βa †2 and ab + βa † b † of two boson creation and annihilation operators are presented. The algebraic procedure given here is based on the work of Shanta et al. 1994] for constructing eigenstates of generalized annihilation operators.

Based on the statistical data from National Bureau of Statistical of China, this paper shows the correlationship between the energy consumption of the provinces and temperature of corresponding capitals. After that Shanghai is researched as an example, and an forecast of Shanghai’s temperature after 20 years is draw out on condition that the energy consumption of this city keeps the same increa...

The new closed form solutions of the (2+1)-dimensional Zabolotskaya–Khokhlov equation are constructed by using the similarity transformations method via Lie group theory. The Zabolotskaya–Khokhlov equation has been reduced into a new partial differential equation with smaller number of independent variables. Further using the similarity transformations method the new partial differential equati...
