Some researchers based on the distinction theory, believe that religious influence on other spheres of social life reduce and in spite of traditional life spheres lead by a set of its values, not by a coherent unit and driven by fragmentation theory of values.  The effect of religion on public life and private areas such as work and family over the area of public policy is effective. The relat...

Using methods of effective field theory, a systematic analysis of the fragmentation functions Da/H(x,mQ, μ) of a hadron H containing a heavy quark Q is performed (with a = Q, Q̄, q, q̄, g). By integrating out pair production of virtual and real heavy quarks, the fragmentation functions are matched onto a single nonperturbative function describing the fragmentation of the heavy quark Q into the ha...

Abstract Iceberg calving strongly controls glacier mass loss, but the fracture processes leading to iceberg formation are poorly understood due stochastic nature of calving. The size distributions icebergs produced during process can yield information on driving and also affect timing, magnitude, spatial distribution ocean fresh water fluxes near glaciers ice sheets. In this study, we apply fra...

This work presents a framework to handle the class fragmentation problem during the design of distributed object databases. The framework works in the conceptual level, and thus uses the object data model to capture the application semantics represented by the user. The proposed framework integrates three modules. The heuristic module defines a set of heuristics to drive the fragmentation of ob...

The investigation of structural graphs has many fields of applications in engineering, especially in applied sciences like as applied chemistry and physics, computer sciences and automation, electronics and telecommunication. The main subject of the paper is to express fragmentation criteria in graph using a new method of investigation: terminal paths. Using terminal paths are defined most of t...

This work presents the application of theory revision to the design of distributed databases to automatically revise a heuristic-based algorithm (called analysis algorithm) through the use of the FORTE system. The analysis algorithm decides the fragmentation technique to be used in each class of the database and its Prolog implementation is provided as the initial domain theory. Fragmentation s...

The recent development of perturbative QCD (PQCD) fragmentation functions has strong impact on quarkonium production. I shall summarize Bc meson production based on these PQCD fragmentation functions, as well as, the highlights of some recent activities on applying these PQCD fragmentation functions to explain anomalous J/ψ and ψ production at the Tevatron. Finally, I discuss a fragmentation mo...
