In this article, the concept and principles of ethnic problem, existing theoretical views conceptual approaches to solving problems, historical-legal basis political mechanisms problems are studied analytically researched. It also reveals issues in mono-ethnic, multi-ethnic, non-ethnic (not based on any groups) states or homogeneous heterogeneous societies.

the aim of the present work is to prepare an adsorption package to simulate adsorption / desorption operation for both single and multi-component systems in an isothermal condition by different mechanisms such as; local adsorption theory and mass transfer resistance (rigorous and approximated methods). different mass transfer resistance mechanisms of pore, solid and bidispersed diffusion, toget...

Pain is not the only defense mechanism that alerts us to a physical hazard — the other is itch, an unpleasant sensation that is distinct from pain because it provokes the desire to scratch. Although pain and itch feel different, these two sensations share many qualities. Both are aversive sensations that evolved to protect us. Moreover, both can become pathological, developing into chronic debi...

Researching efficiency of group-analytic treatment and following Foulkes' principle of the "group-as-a-whole", the methodology was applied. That enabled the evaluation of expected changes of group members individually, as well as the group-as-a-whole. In this study three small groups (20 patients) were followed up and changes were evaluated after second and after fourths years of group analysis...

Invasion mechanisms of pathogens and counteracting defense mechanisms of plants are highly diverse and perpetually evolving. While most classical studies of plant defense have focused only on defense-specific factor-mediated responses, recent work is beginning to shed light on the involvement of non-stress signal components, especially growth and developmental processes. This shift in focus lin...

Abstract In recent years, rather than enclosing data within a single organization, exchanging and combining from different domains has become an emerging practice. Many studies have discussed the economic utility value of exchange, but characteristics that contribute to problem-solving through combination not been fully understood. big interdisciplinary combinations, large-scale with many varia...

Many obstacles impede the successful deployment of sensor networks. In addition to the limited resources issue, security is a major concern especially for applications such as home security monitoring, military, and battle field applications. In this paper we present a defense mechanism against wormhole attacks in wireless sensor networks. Specifically, a simple routing tree protocol is propose...

objective: interventions for people suffering from borderline personality disorder (bpd), such as dialectical behavior therapy, often include a problem-solving component. however, there is an absence of published studies examining the problem-solving abilities of this client group in iran. the study compared inpatients and outpatients with bpd and a control group on problem-solving capabilities...
