Studieswere performed in the laboratory, greenhouse and Þeld to assess the potential ofAgrotis ipsilonmulticapsid nucleopolyhedrovirus (AgipMNPV) and a viral enhancing agent,M2R, for suppression of Agrotis ipsilon (Hufnagel). In laboratory droplet feeding bioassays, AgipMNPV was shown to be highly active against third-instarA. ipsilon.The optical brightenerM2R signiÞcantly reduced LD50 estimate...

در اینجا امکان تصحیح اثر پراش یا جمع آوری انرژی که در اثر پراش بصورت واگراشونده، از دست میرود را با استفاده از روش مزدوج فازی اپتیکی (optical phese conjugtion)، توسط مخلوط چهار موجی تبهکن (dfwm)، بصورت عددی بررسی کرده ایم. این عمل را برای روزنه با قطرهای مختلف pcm با بهره های مختلف انجام داده ایم. با توجه به سرعت کامپیوتری که بکار گرفته شده و برنامه نرم افزاری استفاده شده و مدت اجراء برنامه، جو...

we solve the coupled mode equations governing the chalcogenide nonlinear fiber bragg gratings (fbgs) numerically, and obtain the bistability characteristics. the characteristics of the chalcogenide nonlinear fbgs such as: switching threshold intensity, bistability interval, on-off switching ratio are studied. the effects of fbg length and its third order nonlinear refractive index on fbg charac...

Abstract Fluorescence microscopy based on fluorochrome has been rapidly developed as the candidate for morphological identification of pathogenic fungi over recent years, offering superior rapidity and efficacy traditional culture methods. However, intrinsic quenching properties fluorescein limit clinical application fluorescence imaging. Herein, we report a nano-strategy by converting commerci...

A Zn–Ni alloy was electrodeposited on a Cu electrode at current density of 10–5000 A·m−2, charge 5 × 104 C·m−2, and temperature 293 K in an unagitated zincate solution containing the reaction product epichlorohydrin imidazole (EI polymer) as brightener. The effect EI polymer deposition behavior investigated. transition densities which shifted from normal type to anomalous were 50–100 A·m−2 10–2...

The effect of fig freezing in sugar solution on fig’s quality and sensory traits as well phenolic content during storage was examined. Fresh figs were frozen without any treatment (control - CON), sucrose (30%) (SUC) with ascorbic acid (2%) (SUCAA), stored at -18 ⁰C for 210 days. Samples analyzed every seventy days pH, total soluble solids (TSS), sugars phenolics composition, skin pulp color, t...

we design and simulate a five-port optical router, which is composed of twenty mach-zehnder-based switching elements and twelve waveguide crossings for use in integrated photonic interconnection networks. we simulated and analyzed the operation of the proposed optical router from the aspects of insertion loss, power budget, q-factor and the minimum bit error ratio by use of optisystem simulator...

In this paper, an enhancement design of communication system using optical radio frequency (RF) waves in free space optical communication (FSO) system is presented. To our knowledge, it is the first time that the effect of Gamma-Gamma turbulent channel model on the performance of the proposed system is analyzed and simulated. To obtain an optical communication system with good performance and h...
