An efficient dynamic kinetic resolution (DKR) approach for the synthesis of axially chiral diamines has been developed on basis a ruthenium-catalyzed enantioselective transfer hydrogenation. The strategy relies configurational instability cyclic biaryl aminal precursors in equilibrium with their amino-imine open forms, as supported by DFT calculations. This protocol features broad substrate sco...
To investigate drought tolerant isolates of rhizobial symbioant of lentil (Lens culinaris L.), 12 soil samples were collected from cultivated and non-cultivated area of Golestan, Chaharmahal-O-Bakhtiari and Isfahan provinces. Local cultivars of lentil including Binam Dorosht, Ghazvini and Faridani were planted in each soil sample. After 10 weeks, a total of 324 rhizobial isolates were recovered...
The synthesis of two 2-formylquinolines is reported via the Skraup method followed by SeO(2) oxidation. Each aldehyde is condensed with (1R,2R)-diaminocyclohexane and (R)-BINAM, yielding four enantiomerically-pure bis(imine-quinoline) ligands. The neutral ligands are reacted with ZnCl(2) to give complexes with bis(bidentate) coordination of ZnCl(2) units. X-Ray structural characterization of th...
paddy de-awning using a de-awner increases the uniformity and flow rate of paddy grains through the orifices of hoppers, bucket elevators and chutes. in this study the effects of paddy variety, rotational blade speed and moisture content on performance of a prototype de-awner machine were investigated. the experiment was conducted in a factorial design with three factors, variety (hashemi and b...
A considerable portion of threshing losses and waste of rice takes place in threshing stage. One of the effective factors in threshing losses and waste of threshing units, threshers and harvesting machines, is the drum speed. In this research, effects of three factors including drum speed (five levels), crop moisture content (two levels) and rice common varieties (four varieties) on threshing l...
estimating and determining of rice water requirement, being the main cultivate of rasht region, is crucial for devoting water to this region. equations which are used to calculate the reference evapotranspiration (et0) are not match to all climatic conditions, due to their empirical bases. so, it is necessary to clarify proper methods for each region. crop coefficient (kc) is also the main para...
equal amounts of carbohydrates from various foodstuffs do not increase blood glucose to the same extent. this study was carried out, therefore, in 1996 at the national nutrition and food technology research institute in tehran to determine the glycemic index of split pease, rice (binam), kidney beans, green peas, “lavash” bread and broad bean kernels. diabetic subjects were studied in a clinica...
بررسی تنوع و روابط ژنتیکی بین تعدادی از ارقام برنج با استفاده از صفات زراعی و نشانگرهای مولکولی RAPD
Identification of rice germplasm is necessary for aplication of genetic resources for rice breeding. In this purpose 30 rice genotypes evaluated based on important agronomic traits and RAPD markers. The maximum variation coefficient belonged to unfilled grain (76.6%) and minimum to panicle iength (18.46%). results of Euclidean similarity coefficient and UPGMA algorithm indicated 3 distanced gro...
