Generalizing a result of Furstenberg, we show that for every infinite discrete group $G$, the Bernoulli flow $2^G$ is disjoint from minimal $G$-flow. From this, deduce algebra generated by functions $\mathfrak{A}(G)$ proper subalgebra $\ell^\infty(G)$ and enveloping semigroup universal $M(G)$ quotient $\beta G$. When $G$ countable, also prove any metrizable, $G$-flow, there exists free, it exis...

shah ismail established a dynasty in iran on the premises of nationality and religion. to establish national unity in iran, he announced shia as the official religion. his goal was to strengthen iranian national bonds. the presence of uzbeks in the east and ottomans in the west made it necessary that iranian people reinforce their feeling of patriotism and love for they homeland. shah ismail be...

For any countable group with infinite conjugacy classes we construct a family of forests on the group. each them there is random walk property that its sample paths almost surely converge to geometric boundary forest in way resembles simple walks trees. It allows us identify Poisson and show action free (which, particular, implies non-triviality boundary). As consequence obtain carries such sta...

This study aims to empirically test the impact of the Motivation-Ability-Opportunity(MAO) model on knowledge work. We propose that knowledge work is a function of employees’ motivation, ability and opportunity. In this regard, the aim is to provide empirical support to explain the effects of motivation, ability and opportunity on knowledge-work, which we defined as a knowledge-centered behavior...

In this paper, factors affecting the development and effectiveness of ICT in Iran’s educational system, based on survey results from a group of computer engineering colleagues are discussed. Participants in the study were 22 students studying in Ferdowsi University of Mashhad, selected through a voluntary basis from a pool of students who had taken at least one web-based class at the university...

The aim of this study was to identify the deficiency of uridine monophosphate synthase (DUMPS) and the complex vertebral malformation (CVM) in Iranian Holstein bulls. A total of 144 blood samples were prepared of Holstein bulls in Abbas Abad Animal Breeding Center and Ferdowsi University of Mashhad's Dairy Farm in Khorasan state of Iran. Genomic PCR-RFLP protocol was performed to amplify the po...
