گیاهان دارویی از دیرباز مورد استفاده بشر قرار گرفته اند. این گروه از گیاهان نیز مانند گیاهان دیگر، میزبان برخی از جانوران ریز، از جمله کنه ها می باشند. در این مطالعه که طی سالهای1388-1387 انجام گرفت، کنه های مرتبط با قسمت هوایی و خاک برخی گیاهان دارویی متعلّق به خانواده asteraceae جمع آوری و شناسایی شد. در این مطالعه جمعاً 23 گونه (در 18 جنس از 15 خانواده)متعلّق به زیرراسته پیش استیگمایان و راسته ...

We present simple protocols for oblivious transfer and password-based identification which are secure against general attacks in the noisy-quantum-storage model as defined in R. König, S. Wehner, and J. Wullschleger [e-print arXiv:0906.1030]. We argue that a technical tool from König et al. suffices to prove security of the known protocols. Whereas the more involved protocol for oblivious trans...

Voriconazole (VRC), (2R,3S)-2-(2,4-difluorophenyl)-3-(5fluoro-4-pyrimidinyl)-1-(1H-1,2,4-triazol-1-yl)-2-butanol)) is a triazole antifungal derived from the structure of fluconazole (Perea et al., 2000). Compared to fluconazole, voriconazole has an enhanced antifungal spectrum with activity against Aspergillus, Candida, Scedosporium and Fusarium species (Cuenca-Estrella et al., 1998; Espinel-In...

The gas permeability of plastic films is important in packaging, containment, and agricultural fumigation. Recently, an approach for estimating the mass transfer coefficient of vapors across a film was presented by Papiernik et al. (2001). The mass transfer coefficient is an intrinsic property of a film-chemical combination, independent of the concentration gradient maintained across the film. ...

Measuring systemic oxygen consumption (VO2) is a fundamental part of hemodynamic and oxygen transport assessment when using the Fick principle. This measure is pivotal for children with congenital heart disease, at cardiac catheterization and in the Intensive Care Unit (ICU) after cardiopulmonary bypass surgery (CPB). According to the direct Fick principle (Fick, 1870), VO2 may be combined with...

In this work, the effects of operative parameters on CH4, CO2, O2, and N2 membrane gas separation for poly (4-methyl-1-pentane) (PMP) membrane modified by adding nanoparticles of TiO2, ZnO, and Al2O3 are assessed and investigated. The operative parameters were type and percentage of nanoparticles, and cross membrane pr...

we study entanglement and squeezing of a cluster of spin systems under the influence of the two-axis countertwisting hamiltonian. the squeezing parameters given by wineland et al and also by kitagawa et al. are chosen as the criteria of spin squeezing. the criterion of pairwise entanglement is chosen to be the concurrence and that of the bipartite entanglement the linear entropy. we also define...

This paper presents a complete analytical solution to describe tidal groundwater level fluctuations in a coastal subsurface system. The system consists of two aquifers and a leaky layer between them. Previous solutions of Jacob [Flow of groundwater, in: H. Rouse (Ed.), Engineering Hydraulics, Wiley, New York, 1950, pp. 321–386], Jiao and Tang [Water Resour. Res. 35 (3) (1999) 747], Li and Jiao ...
