The main source of seed filling results from the photosynthesis green tissue closest to sinks in capitula. To evaluate role different leaf strata and capitula yield its components Safflower genotypes, a field study was performed as factorial experiment based on RCBD 3 replicates East Azarbaijan Agricultural Natural Resources Research Education Center 2008. used factors this were: two genotypes ...

BACKGROUND Fasciolosis in livestock is a crucial concern in the globe, mainly due to its impact on human health. The aim of this study was to determine the rate of infection with Fasciola gigantica (Cobbold, 1855) larvae in the field-collected snails of Lymnaea auricularia (Linnaeus, 1785) from northwestern Iran using a molecular approach. METHODS A total of 6,759 pond snails were collected f...

Hearing loss (HL) is the most frequent sensory defect affecting 1 in 1000 neonates. This can occur due to genetic or environmental causes or both. The genetic causes are very heterogenous and over 100 loci have been identified to cause autosomal recessive non - syndromic hearing loss (ARNSHL). The aim of this study was to determine the contribution of the LRTOMT gene mutations in causing ARNSHL...

Tillage is the base operation in agriculture and its energy represents a considerable portion of the energy utilized in crop production. To measure the implement force requirements, are used dynamometers that are pull or three-point hitch types. In this research, an 82 kW research tractor equipped with an instrumentation system was used to determine the draft force inputs for four common tillag...

Margollus bokanicus n. sp., collected from natural habitats in Khorasaneh district, Bokan, West Azarbaijan province, Iran, is described. Morphological and morphometric data are provided as well as drawings and light microscopy illustrations. The new species is characterized by a medium size body length (0.60 to 0.73 mm), labial and postlabial sclerotizations, lip region 7-μm wide, offset by con...

Background & Aims: Hydatidosis as a parasitic zoonotic infection is endemic in Iran, but systematic information about the exact rate of hydatidosis prevalence in different regions of the country is very limited. Because of the importance of disease this study was undertaken in East-azarbaijan province to determine the prevalence rate of hydatidosis by ELISA method. Methods: Totally, 1500 serum ...

the most commonly used utility functional forms are reviewed and their properties compared. then, using data collected from west azarbaijan province, utility functions are estimated and absolute risk aversion coefficients measured. exponential and expopower utility functions classified all farmers as risk averse, but quadratic and cubic utility functions classified 75% and 65% of farmers as...

BACKGROUND Infection with Ornithobilharzia turkestanicum has been reported in a wide range of animals worldwide. This study was undertaken to assess the utility of polymerase chain reaction (PCR), for detecting the infection with O. turkestanicum larvae stages in Lymnaea gedrosiana. METHODS A total of 6,759 Lymnaeidae snails were collected from six aquatic habitats in West Azarbaijan, northwe...

To assess genetic diversity and maternal origin of Turkish and Iranian native chicken breeds, we analyzed the mtDNA D-loop sequences of 222 chickens from 2 Turkish (Denizli and Gerze) and 7 Iranian (White Marandi, Black Marandi, Naked Neck, Common Breed, Lari, West Azarbaijan, and New Hampshire) native chicken breeds, together with the available reference sequences of G. gallus gallus in GenBan...
