abstract: about 60% of total premium of insurance industry is pertained?to life policies in the world; while the life insurance total premium in iran is less than 6% of total premium in insurance industry in 2008 (sigma, no 3/2009). among the reasons that discourage the life insurance industry is the problem of adverse selection. adverse selection theory describes a situation where the inf...
ninety one monoconidial bipolaris isolates were obtained from lesions on different parts of rice in different locations of mazandaran province during the summer of 2009. bipolaris species were identified using morphological features such as color and shape of colony and color and size of conidia and conidiophores. the isolates were separated into two species; 85 (93.4%) isolates belonged to bip...
Rhizobia are a widely distributed and abundant soil bacteria belonging to the alpha subclass of the Proteobacteria. The aim of this study was the estimation of rhizobial diversity in different genera using several molecular markers for genomic fingerprinting and the detection of certain symbiotic properties of rhizobia. Phage typing was done in order to detect different susceptibilities to atta...
based on the latest records of typhlops vermicularis merrem, 1820 from iran, this species is distributed in the northern and southern regions of the country. in this study, new records of typhlops vermicularis are presented and it is shown that distribution range of this species is extended towards the eastern and western iran, and according to the new distribution map, it can be assumed that t...
Since 1984, DNA tests based on the highly repeated subtelomeric sequences of Plasmodium falciparum (rep 20) have been frequently used in malaria diagnosis. Rep 20 is very specific for this parasite, and is made of 21 bp units, organized in repeated blocks with direct and inverted orientation. Based in this particular organization, we selected a unique consensus oligonucleotide (pf-21) to drive ...
in the first part of this thesis we explored wetting and its dynamics for small droplets. first, we showed how a simple feature of water droplets on a surface, i.e. laplace pressure, can be exploited to build a micropump. we investigated capillary pumping in microchannels both experimentally and numerically. putting two droplets of different sizes at the in/outlet of a microchannel, will ge...
in this thesis, we exploit a simple and suitable method for immobilization of copper(ii) complex of 4?-phenyl-terpyridine on activated multi-walled carbon nanotubes [amwcnts-o-cu(ii)-phtpy]. this nanostructure was characterized by various physico-chemical techniques. to ensure the efficiency and fidelity of copper species, the implementation of three-component strategies in click-chemistry all...
The present report assesses the association between clonal groupings, disease, and the virulence fingerprint of 76 South African Helicobacter pylori cagA(+) strains isolated from 57 Cape-colored subjects. Two methods, repetitive extragenic palindromic (REP)-PCR and random amplified polymorphic DNA (RAPD)-PCR, were used to generate DNA fingerprints, and computer-assisted analysis was used to der...
monumental changes occurring on a daily basis have altered the world into a global village of expanding technology and shrinking geography in which preparing language learners for intercultural communication seems to be a sine qua non for modern language education. employing a cross-sectional design in its first phase, this study investigated the intercultural sensitivity and language proficien...
dendrimer synthesis strategies now provide virtual control of macromolecular nanostructures as a function of size and surface/interior functionality. these strategies involve the covalent assembly of hierarchical components reactive monomers , branch cells or dendron’s around atomic or molecular cores according to divergent/convergent dendrite branching principles.combinon of two or more dendri...
