In this study, Four Wave Mixing (FWM) characteristics in photonic crystal fibers are investigated. The effect of channel spacing, phase mismatching, and fiber length on FWM efficiency have been studied. The variation of idler frequency which obtained by this technique with pumping and signal wavelengths has been discussed. The effect of fiber dispersion has been taken into account; we obtain th...
to synthesize, the works of their contributors. They also attempt a useful, if somewhat narrowly conceived, taxonomy of ethers and discuss some of the interesting questions raised by and about the recent historiography of the subject. On the whole, historians of science should welcome this book, which shows how far and in how many directions the discipline has travelled since E. T. Whittaker's ...
Active immunization is an effective means of blocking the pharmacodynamic effects of drugs and holds promise as a treatment for heroin addiction. Previously, we demonstrated the efficacy of our first-generation vaccine in blocking heroin self-administration in rats, however, many vaccine components can be modified to further improve performance. Herein we examine the effects of varying heroin v...
در این مطالعه، تعداد 14 گونه از 9 جنس متعلق به مگسهای میوه از روی 15 گونه از 9 جنس گیاهان تیره میناسیان، در طی سالهای 1390 تا 1392 جمعآوری و شناسایی گردید و در بین آنها سه گونه Centaurea depressa (Bieberstein, 1808)، Achillea millefolium Linnaeus, 1753 وC. macrocephala Puschk. ex Willd, 1803 برای اولینبار از ایران بهعنوان میزبان این حشرات گزارش شدند. گونههای Terellia colon (Meigen, 1826) ...
There is growing evidence that plasmacytoid dendritic cells (pDC) are involved in the innate recognition of various microbes. However, the precise consequences of pathogen recognition on pDC activation and function are incompletely understood. Using a novel transgenic mouse model that facilitates the isolation of highly pure pDC populations, we found that influenza virus PR/8, a TLR7 ligand, an...
