this article discuss about public policy implementation for cultural space in iran. we want to design a model for implementing cultural policy. and will explain the factors of the model and the relations between them. then we will compare the proposed model with the other famous models on the word. the proposed model created with the qualitative methodology which is grounded theory (gt). with p...

We examine the problem of constructing three generation free fermionic string models with grand unified gauge groups. We attempt the construction of G × G models, where G is a grand unified group realized at level 1. This structure allows those Higgs representations to appear which are necessary to break the symmetry down to the standard model gauge group. For G = SO(10), we find only models wi...

An analysis of the kinetic coefficient of crystal growth U(kin), recently proposed by Ediger et al. [J. Chem. Phys. 128, 034709 (2008)], indicates that the Stokes-Einstein/Eyring (SE/E) equation does not describe the diffusion process controlling crystal growth rates in fragile glass-forming liquids. U(kin) was defined using the normal growth model and tested for crystal data for inorganic and ...

For polar-cap models based on electromagnetic cascades induced by curvature radiation of beam particles we calculate broad-band high-energy spectra of pulsed emission expected for classical (∼ 10 G) and millisecond pulsars (∼ 10 G). The spectra are a superposition of curvature and synchrotron radiation components and most of their detailed features depend significantly on the magnetic field str...

BACKGROUND Sexually transmitted bacterial rectal infections are objective markers of HIV risk behavior. Quantifying HIV risk among men who have sex with men (MSM) who have had these infections can inform prevention efforts. We measured HIV risk among MSM who have and those who have not been diagnosed with rectal Chlamydia trachomatis (CT) and/or rectal Neisseria gonorrhoeae (GC). METHODS HIV ...

OBJECTIVE This article is to establish recommendations for conducting quantitative synthesis, or meta-analysis, using study-level data in comparative effectiveness reviews (CERs) for the Evidence-based Practice Center (EPC) program of the Agency for Healthcare Research and Quality. STUDY DESIGN AND SETTING We focused on recurrent issues in the EPC program and the recommendations were develope...

We compute up-down asymmetries for atmospheric neutrino induced electron and muon events in the SuperKamiokande detector for the following neutrino oscillation models: (A) maximally mixed νμ− ντ or νμ− νs, (B) maximally mixed νμ− νe, (C) threefold maximal mixing between νe, νμ and ντ , and (D) neutrino oscillations via Equivalence Principle or Lorentz invariance violation. We emphasise the role...

In this paper, we consider the possibility of generating observed baryon asymmetry Universe via leptogenesis in context a triplet fermion-mediated type-III seesaw model neutrino mass. With hierarchical spectrum additional fermions, lower bound on lightest mass is $\ensuremath{\sim}{10}^{10}\text{ }\text{ }\mathrm{GeV}$ for successful leptogenesis, couple orders higher than that type-I case. We ...
