BACKGROUND The supply of industrially relevant biocatalysts demands an easy and efficient protein production in high yield. In a conventional approach, a recombinant protein is produced in a heterologous host enabling the manipulation of multiple parameters including expression plasmids, growth conditions and regulation of protein biosynthesis. In this study, the generation of homomultimeric fu...
Research was conducted during 1999 to 2009 to develop and introduce a new common millet (Panicum miliaceum) cultivar suitable for areas with short growing seasons in Iran. Several common millet populations collected from different locations of Iran were evaluated in research farm of Seed and Plant Improvement Institute in Karaj and based on yield, agronomic traits and tolerance to abiotic stres...
chickpea (cicer arietinum l.) is one of the most important crops worldwide that is a subject of many plant breeding programs in many countries. in addition, climates are changing all over the world and drought becomes one of the most serious problems versus yield of crops. in order to screen drought tolerant genotype in chickpea, twenty genotypes were tested under rainfed and irrigated conditio...
Succinimidinium hydrogensulfate ([H-Suc]HSO4), as a new and stable derivative of succinimide, is easily prepared by the reaction of succinimide with neat sulfuric acid. This ionic liquid can be used as an efficient catalyst for the acetylation of alcohols, phenols, thiols and amines at room temperature under mild and solvent free conditions. All the products are separated and identified using d...
A powerful and convenient reaction procedure for the C-N coupling reaction (the Buchwald-Hartwig reaction), yielding products of N-arylanilines and N-arylamines in both conventional heating and microwave irradiation has been reported. The protocol utilizes a stable and new supper ferromagnetic nanoparticle chelating N-heterocyclic dicarbene palladium(II) complex (Pd-NHC) as catalyst which helps...
Several applications of methods from non-linear algebra to the stable set problem in graphs are surveyed. The most recent work sketched is joint with A. Schrijver and involves non-linear inequalities. These yield a procedure to generate facets of the stable set polytope. If a class of graphs has the property that all facets of the stable set polytope can be generated this way in a bounded numbe...
to evaluate the yield and yield components in additive intercropping system of grain sorghum (sorghum bicolor l.) and cowpea (vigna unguiculata l.) under limited irrigation condition, an experiment was conducted in research farm of college of agriculture, university of tehran, during spring 2006. the experimental treatments were arranged in split plots based on a complete randomized block desig...
this study was conducted to determine grain yield stability of rainfed promising barley genotypes across six rainfed research stations (maragheh, sararood, uromieh, qamloo, zanjan and ardabil) under cold and semi-cold conditions during three cropping seasons (2006-2009) in iran. the studied genotypes were 10 promising barley lines along with two checks (one local and one newly released variety,...
this study was performed for determine stability of the 18 promising barley lines and two check lines nosrat and mb-86-5 in six parts of the temperate zone including karaj, isfahan, birjand, varamin, zarghan and nishapur based on randomized complete block design)rcbd( with three replications and in two cropping seasons (2009-2011). following combined analysis, grain yield stability assessment w...
The time-course of chromosomal aberrations in three radiation victims of the 1994 Estonian accident was followed for a period of seven post accident years encompassing 15 samples. Chromosome painting was performed and chromosomal aberrations involving the painted chromosomes were scored using a developed version of the PAINT nomenclature. Metaphases containing aberrations were captured with an ...
