in order to study the effect of planting pattern and herbicide application on corn (zea mays l.) grain yield and weeds control, an experiment was carried out in 2007 at varamin research station of plant protection research institute. the experimental design was a randomized complete block in a split plot arrangement with 4 replications. experimental factors consisted of planting patterns at 4 l...
Sixteen avian influenza (AI) H9N2 viruses were isolated from disease outbreaks in different parts of Iranduring (1998–2001). These AI isolates were used for pathogenicity, haemagglutinin (HA) gene variation andphylogenetic analysis. Results in both pathogenicity tests and HA gene cleavage site sequence detectionrepresented a non-highly pathogenic feature for all Iranian AI isolates studied. The...
آزمایش مزرعه ای با هدف تأثیر تلفیق روش های کنترل مکانیکی با علف کش ها بر عملکرد و اجزاء عملکرد سویا در سال زراعی 83-1382 در قالب طرح بلوک های کامل تصادفی با 18 تیمار و سه تکرار در مزرعه ی پژوهشی دانشکده کشاورزی دانشگاه تهران (کرج) اجرا شد. تیمارها شامل گروه های: 1- کاربرد مجزای علف کش های تریفلورالین (g ai/ha960)، آلاکلر (g ai/ha2400)، بنتازون (g ai/ha1200) و اکسی فلورفن (g ai/ha360) بترتیب به ...
background and aims: hemagglutinin (ha) protein of avian influenza (ai) plays an essential role in the virus pathogenicity. ai h9n2 subtype causes significant economic loss in broiler and layer in poultry farms in iran. ai viruses have a great involvement in evolutionary changes at nucleotide and amino acid levels and vaccines could induce faster rates of such changes. up-dated understanding of...
The term amelogenesis imperfecta (AI) describes a diverse group of hereditary conditions primarily affecting the quality and/or quantity of dental enamel which are usually not associated with generalized findings. It affects all teeth in both the primary and permanent dentitions. The estimated frequency of AI is one in 14000. Disruptions occurring during histodifferentiation, apposition, and mi...
hossein qoli khan llkhani bakhtiari was murdered based on an order given by naser-ai-din shah and his son, zel-ai-sultan. prince farhad mirza mot'amed-ai-dowle, governor of fars had a major hand in the slain. it is believed he had animosities with the llkhani bakhtiari therefore stirring the qajar king against him. differences between qashgaiee, bakhtiari tribes and falard ownership was th...
in the present study, changes of values of serum 17ß-estradiol (e2), asparate amino teransferase (ast), alanine amino transferase (alt) and lactate dehydrogenase (ldh) following intraperitoneal (i.p) injection with the aromatase inhibitor (ai) letrozole were investigated in rainbow trout (oncorhynchus mykiss). forty- eight apparently healthy rainbow trout (mean weight of 845 g) divided in four ...
