background and objectives: oleaceae family contains approximately 20 species of small trees and ancient world of the mediterranean, north africa, southeast asia, north to southern china, scotland and east australia have a wide dispersion. they are evergreen and have small leaves that are integrated have been met and the fruit is drup. olive trees resistant to drought and adapt to poor soils and...
Based on the limited resources available to algal flora in Yazd province in the center of Iran, cultivation, purification and identification of soil algae from seven sites was performed in summer 2013. The soil samples were processed for analysis of Cd, Pb contents. The present paper attempts to analyze survey of soil blue-green algal identification in different types of stations, using morphol...
background: classical bacteriological detection of brucella species from food, and environment is routinely carried out based on morphological and biochemical characteristics. however, for increasing specificity and sensitivity of species identification methods, development of a molecular assay is necessary that was main aim of this study. methods: panel of some reference strains belonging to t...
background: fish are constantly exposed to various pathogens and parasites in particular. gyrodactylus from platyhelminthes is an important monogenean ectoparasite that can cause disease and economical losses to cultured, wild, salt and fresh water and ornamental fish. gyrodactylus appears to be one of the most prevalent parasites of ornamental fish especially in cyprinids. objectives: the pres...
background: accurate identification of sheep nematodes is a critical point in epidemiological studies and monitoring of drug resistance in flocks. however, due to a close morphological similarity between the eggs and larval stages of many of these nematodes,such identification is not a trivial task. there are a number of studies showing that molecular targets in ribosomal dna (internal transcri...
on- the-job training on of the most effective tools for managers to cope with the changing organizational environment. it grantess suitable services to customers, particularly in public service enterprises. if such training os goal oriented, planned systematically, and tailored to the employees, job content, then not only it could increase employees and organizational performance, but also it c...
in this investigation the effect of external field on the electron density of nanostructures of cds, cdse, cdte, gaas and polymeric structure of three, four, five and six units of cds as a kind of nanosolar cells has been studied theoretically. as modeling this system in nanodimension, molecular structures has used. specific properties of molecular structures permit us to consider different sym...
Conventional methods for fungal identification in the clinical laboratory rely on morphological andphysiological tests. These tests often need several days or weeks to complete and are frequentlyunspecific. Molecular identification mostly implies sequencing, which is relatively expensive andtime-consuming, as well as impractical for large numbers of isolates. The Rolling CircleAmplification app...
background and purpose: trichosporon is a genus of anamorphic basidiomycetous yeast which is widely distributed in nature and is found in tropical and temperate areas. the aim of this work was to study the isolation, identification and molecular analysis of trichosporon species in soil. materials and methods: in order to isolate and identify trichosporon species in soil, 30 samples were collect...
