Sir,?In reply to your correspondent Adolphe Passanha, M. A., who asks if it is usual to obtain a green colour when dispensing Antipyrin and Sp. Eth. Nit. together, I may perhaps be allowed to state such is the usual result, unless the Sp. Eth. Nit. is freely diluted and added last, which even then will not always prevent this characteristic colour. See Squire, 15th Edition, p. 73. Tests.?The aq...
The optical charge pumping method (OCPM) for extracting the spatial distribution of the interface state density (Nit) is proposed. By combining the concept of local threshold voltage in CPM and the drain current generated by the trapped electrons excited from the interface states to the conduction band by incident photons, the Nit is successfully extracted in the SONOS-type flash memory cell tr...
Fusarium solain is the most important pathogen of huge range of plant hosts, especially potato in the word, which causes tuber rot in storage and root rot of potato plants in fields. Fifty four isolates from potato, bean, chickpea and cucurbit (melon, watermelon and cucumber) was subjected in a study through analysis of vegetative compatibility groups (VCGs) and rep-PCR DNA fingerprinting. Nit ...
دراین تحقیق گروههای سازگاری رویشی (vcg)چهل جدایه fusarium oxysporum f.sp. tuberosi، عامل بیماری های مهم سیب زمینی در سه مرحله در انبار و مزرعه شامل پوسیدگی خشک فوزاریمی پژمردگی و پوسیدگی انتهایی ساقة سیب زمینی که از مناطق مختلف سیب زمینی کاری استان خراسان جمع آوری شده بودند، با استفاده از جهش یافتگان نیت تعیین شد. ابتدا جهش یافتگان نیت بصورت سکتورهائی در محیط های مختلف کلرات دار تولید شدند. سپس...
This thesis has assessed the prevalence of spontaneous tinnitus (ST), noiseinduced tinnitus (NIT) and temporary threshold shift (TTS) in children and adolescents as well as investigated some of the audiometric, medical and psychological characteristics of young subjects with tinnitus. Additionally, long-term effects of noise exposure were examined in relation to ST, NIT and TTS. The methods emp...
Background: Random induced mutation by gamma radiation is one of the genetic manipulation strategies to improve the antagonistic ability of biocontrol agents. Objectives: This study aimed to induce mutants with more sporulation, colonization rate leading to enhanced antagonistic ability (in vitro assay) comparing to wild type (WT) and the assessment of genetic differences (in situ evaluat...
قارچ Glomerella cingulataعامل بیماری آنتراکنوز درختان مرکبات در شمال و جنوب ایران است. 67 جدایه تک اسپور شده به دست آمده از درختان مرکبات استان مازندران برای این بررسی استفاده شد. تشخیص هموتال و هتروتال بودن قارچ در این آزمایش روی محیط اختصاصی YPSS انجام شد. برای تشخیص هموتال بودن، ابتدا جدایه‌ها به تنهایی روی این محیط کشت شدند و در نور متناوب و دمای ?C21 به مدت 21-15 روز قرار گرفتند. ارزیابی...
Vegetative compatibility groups (VCGs) are determined for many fungi to test for the ability of fungal isolates to undergo heterokaryon formation. In several fungal plant pathogens, isolates belonging to a VCG have been shown to share significantly higher genetic similarity than those of different VCGs. In this study we sought to examine the relationship between VCG and genetic similarity of an...
