in order to evaluate the yield and yield components of rice (oryza sativa l. cv. tarom hashemi) in integrated rice, duck and azolla, an experiment was conducted at the research farm of sari university of agricultural sciences and natural resources during 2012. experiment was arranged in split plot based on a randomized complete block design with three replications. the number of ducks as main p...

To evaluate different methods for the identification of methicillin-resistant Staphylococci and their reliability, 112 Staphylococcal isolates (32 Staphylococcus aureus isolates and 80 coagulase negative Staphylococci isolates “CoNS”) were collected from 118 nasal swab cultures and were subjected to three methods to detect oxacillin susceptibility of the isolates. The three methods were oxacill...

vitamin c, an antioxidant substance soluble in water, can react with amino groups of proteins to form schiff bases. as diabetes leads to glycation of various protein which has effect on structure and biochemical activity of them, the inhibition of this process seems very vital. for several years researches in this field have done their best to recognize the antidiabetics compounds. the aim of t...

A series of titanium pyridonate complexes have been synthesized under very mild reaction conditions from a common precursor, Ti(NMe2)4. These complexes have been explored as initiators for the ring-opening polymerization of rac-lactide and ε-caprolactone and have proven to be competitive with leading titanium initiators. Furthermore, these complexes have been shown to be competent initiators fo...

due to variation in economic value of different varieties of rice, reports indicating the possibility of mixing different varieties on the market. applying image processing and neural networks techniques to classify rice varieties is a method which can increase the accuracy of the classification process in real applications. in this study, several morphological features of rice seeds’ images we...

Barley yellow dwarf virus (BYDV) is a phloem limited virus that is persistently transmitted by aphids. Due to huge yield losses in agriculture, the virus is of high economic relevance. Since the control of the virus itself is not possible, tolerant barley genotypes are considered as the most effective approach to avoid yield losses. Although several genes and quantitative trait loci are known a...

the fungal disease, ascochyta blight, caused by ascochyta rabiei is a major yield limiting factor of chickpea (cicer arietinum l.) in many countries, including iran. identification of resistance sources against races or pathotypes of the fungus causing this disease is required for breeding resistant chickpea cultivars. reaction of six selected genotypes of iranian chickpea collection was evalua...

Seven rhesus macaques were infected intradermally with 10(7) promastigotes of Leishmania (Leishmania) major. All monkeys developed a localized, ulcerative, self-healing nodular skin lesion at the site of inoculation of the parasite. Non-specific chronic inflammation and/or tuberculoid-type granulomatous reaction were the main histopathological manifestations of the disease. Serum Leishmania-spe...
