fusarium head blight (fhb) or wheat scab is one of the destructive diseases that cause considerable loss in grain quality in cereal cultivated around the worldwide due to the production of trichotecen mycotoxin in the panicle. type b trichothecenes including nivalenol (niv), deoxynivalenol (don), 3-acetyl deoxynivalenol (3-acdon) and 15-deoxynivalenol (15-acdon) are considered to be major toxin...

in this paper, absorption spectra of both solution and films of cyano azobenzene polymer are investigated. the analysis of overlapped absorption spectra of polymer, related to trans and cis isomers, shows that the population of cis isomers is higher than trans isomers. it means that, cyano azobenzene molecules have a folded structure in polymer, in thermal equilibrium. presence of cyano molecul...

this paper addresses the issue of the relationship between the type of organizational / economic structure and organizational entrepreneurship in small- and- medium- sized enterprises (smes). it further provides discussions on mechanical/organic structures as well as organizational entrepreneurship and knowledge structure. in another section, the methodology of the research includes hypotheses,...

high through put sequencing of single nucleotide polymorphisms (snp) has revolutionized the fine scale analysis of the population structure in different species. various methods have been proposed and used for the study of population structure using whole-genome marker data that each has advantages and disadvantages with respect to their characteristics. super paramagnetic clustering (spc) whic...

Cornelian cherry (Cornus mas L.), considered as the ancestor of cultivated trees in Arasbaran region, is a medicinally and economically plant species. However, little is known about genetic diversity, breeding programs, and population structure of this species in mentioned region. Keeping this in view, the main objectives of present study were to analysis the genetic diversity, phyloge...

introduction spatial studies as the main tools for the detailed study of all tangible and intangible aspects of regions have special ranks among all kinds of planning. the conformity of this organization with physical environment forms the spatial structure of which is usually observed as a distributed and isotropic spatial structure, focus and polar, unbalanced and haphazard, random and balanc...
