herpes simplex virus type 1 (hsv-1) with a worldwide distribution has been reported in all human populations, resulting in a clinical spectrum of infections. although hsv type 2 (hsv-2) is known as the most common cause of genital herpes, an increasing number of cases with genital herpes are caused by hsv-1. the present study aimed to discuss the changes in the epidemiology of hsv-1 infection i...

in this paper, we study spacelike dual biharmonic curves. we characterize spacelike dual biharmonic curves in terms of their curvature and torsion in the lorentzian dual heisenberg group . we give necessary and sufficient conditions for spacelike dual biharmonic curves in the lorentzian dual heisenberg group . therefore, we prove that all spacelike dual biharmonic curves are spacelike dual heli...

in this paper we introduce the notion of classical quasi-primary submodules that generalizes the concept of classical primary submodules. then, we investigate decomposition and minimal decomposition into classical quasi-primary submodules. in particular, existence and uniqueness of classical quasi-primary decompositions in finitely generated modules over noetherian rings are proved. moreover, w...

Let $mathcal{A}$ and $mathcal{B}$ be two $C^{*}$-algebras such that $mathcal{B}$ is prime. In this paper, we investigate the additivity of maps $Phi$ from $mathcal{A}$ onto $mathcal{B}$ that are bijective, unital and satisfy $Phi(AP+eta PA^{*})=Phi(A)Phi(P)+eta Phi(P)Phi(A)^{*},$ for all $Ainmathcal{A}$ and $Pin{P_{1},I_{mathcal{A}}-P_{1}}$ where $P_{1}$ is a nontrivial projection in $mathcal{A...

Let $R$ be a commutative Noetherian ring and let $fa$, $fb$ be two ideals of $R$ such that $R/({fa+fb})$ is Artinian. Let $M$, $N$ be two finitely generated $R$-modules. We prove that $H_{fb}^j(H_{fa}^t(M,N))$ is Artinian for $j=0,1$, where $t=inf{iin{mathbb{N}_0}: H_{fa}^i(M,N)$ is not finitelygenerated $}$. Also, we prove that if $DimSupp(H_{fa}^i(M,N))leq 2$, then $H_{fb}^1(H_{fa}^i(M,N))$ i...

in this paper, the (m+1)-step adams-bashforth, adams-moulton, and predictor-correctormethods are used to solve rst-order linear fuzzy ordinary dierential equations. the conceptsof fuzzy interpolation and generalised strongly dierentiability are used, to obtaingeneral algorithms. each of these algorithms has advantages over current methods. moreover,for each algorithm a convergence formula can b...

A fluorescent probe, 7-(diethylamino)-2-oxo-2H-chromene-4-carbaldehyde (probe 1), was designed and synthesized for the sensitive detection of hydrazine. The addition of N2H4 caused the fluorescence intensity of probe 1 to decrease. The probe's fluorescence was turn-off after adding N2H4, which could be observed under UV light at 365 nm. Moreover, once treated with different concentrations N2H4 ...

conclusions regarding the importance of metallo-beta-lactamase (mbl) produced by pseudomonas spp. isolated from hospitals, quick identification of clinical samples should be considered as an important and basic step to treat and control infections caused by pseudomonas spp. results strains with mic > 4 µg/ml were investigated by phenotypic and genotypic methods. in the current study the rate of...

herpes simplex virus type 1 (hsv-1) is a member of the herpesviridae family that causes herpetic disease in human. during the last 25-30 years, many investigations have been conducted on pathogenesis and molecular biology of this virus in several countries. in iran hsv-1 has been isolated from patients and detected using immunological techniques. in this study, we investigated the molecular asp...
