Two chlamydial species C. pneumonia and C. psittaci have important role in respiratory infections. In this survey a primer pair was designed in order to differentiate these two species in one step by single PCR. This differentiation was obtained by having specific product length for each one. All experiments confirmed that the product length in these two species were distinguishable.&nb...

introduction: differential diagnosis of potential pathogenic entamoeba histological from non-pathogenic entamoeba dispar by a molecular method. material and methods: one pair of primers designed based on sequence of genomic dna coding the 30kd surface antigen of e.histolytica/e.dispar. a 374 base pair pcr product was amplified by using the primers. electrophoretic patterns of pcr product digest...
abstract in first part of this project, the use of a new and biguanid-like catalyst supported on silica as a recyclable catalyst provides a new route for the synthesis of a variety of arylalkylidene rhodanine derivatives through knoevenagle reaction in at present of solvent at room temperature. rhodanine derivatives and especially arylalkylidene rhodanines have proven to be attractive compound...
Beginning with Tiebout (1956), numerous studies have argued that we should expect to see differences in public services among localities as a result of people “voting with their feet”. Here, we consider differentiation in public services as a way of reducing competition among localities (cities). If cities finance their public services with a property tax that generates “tax competition”, we fi...
This paper analyses price competition between two firms producing horizontally and vertically differentiated goods. These are assumed to be credence goods, as consumers can hardly ascertain the quality of the commodities. We provide sufficient conditions for the existence of a unique price equilibrium and we characterize it. To illustrate the model, we adapt it to represent a newspapers’ indust...
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...

Companies that simply wish to exist must now evolve new products at an increasing rate to enhance their competitive posture or even to survive. There are no sacred niches that can be harvested for long periods of time We must also be aware of the fact that compan...
