Communication Within and Among Faith-Based Organizationsin Community Empowerment Program

The issue of this research is concerning the communication within and among Zakat Management Organizations (OPZs) as Faith-Based Organization (FBO). The main research problem is how OPZ(s) can successfullydevelop cooperationin increasing both public trust and institutional productivity. Interpretive Approach through Social Construction Theory was used as a reference to see the process of organizational communication through OPZ’s communicator ethos. The research method used was qualitative with a technique of case study, and informants were from OPZ’s West Java unit. The results showed that the communicator ethos as a source of credibility in communicationwithin and among OPZs, derived from Islamic Teachings, applicable (positive)laws, and basic guidelines of OPZs, can produce organizational values as the basis of implementing cooperation in community empowerment programs. Cooperation among OPZsin an empowerment program is more related to personal power and interpersonal power aspectsthan to political power aspect. There is a need to strengthen openness and mutual trust values among the OPZs, changes in zakat regulation, more transparent, accountable and equitable governance in order to increase trust, realization of zakat potentials, and prosperity

Chiral Modulations in Curved Space I: Formalism

The goal of this paper is to present a formalism that allows to handle four-fermion effective theories at finite temperature and density in curved space. The formalism is based on the use of the effective action and zeta function regularization, supports the inclusion of inhomogeneous and anisotropic phases. One of the key points of the method is the use of a non-perturbative ansatz for the heat-kernel that returns the effective action in partially resummed form, providing a way to go beyond the approximations based on the Ginzburg-Landau expansion for the partition function. The effective action for the case of ultra-static Riemannian spacetimes with compact spatial section is discussed in general and a series representation, valid when the chemical potential satisfies a certain constraint, is derived. To see the formalism at work, we consider the case of static Einstein spaces at zero chemical potential. Although in this case we expect inhomogeneous phases to occur only as meta-stable states, the problem is complex enough and allows to illustrate how to implement numerical studies of inhomogeneous phases in curved space. Finally, we extend the formalism to include arbitrary chemical potentials and obtain the analytical continuation of the effective action in curved space.Comment: 22 pages, 3 figures; version to appear in JHE

Force Constants of Cu Crystals from Diffuse Neutron Scattering Measurement

Diffuse neutron scattering measurement on Cu crystals was performed at 10 K and 300 K. Oscillatory forms were observed in the diffuse scattering intensities. The observed diffuse scattering intensities are analyzed by including the correlation effects among thermal displacements of atoms in the theory. Using the values of correlation effects among neighboring atoms and the values of Debye-Waller temperature parameter, force constants among first, second and third nearest neighboring atoms have been evaluated. The result of correlation effects in Cu crystals are compared to that of ionic crystal and semiconductor. The relation between correlation effects and the inter-atomic distance is not depending much on the crystal binding types. Received: 12 October 2010; Revised: 22 October 2010; Accepted: 16 December 201

A medium-range air combat game solution by a pilot advisory system

Air-to-air combat between two aggressive aircraft , both equipped with medium-range guided missiles, is .a key element of future air warfare. This dynamic coni lict can be viewed as an interaction of a twotarget diiferential game (between the air--craft) and two independent missileaircraft pursuit-evasion games. The information structure is, however, rather intricate: though perfect information can be assumed between the two aircraft, the missiles have a limited detection range, beyond which information has to be forwarded by the launching aircraft. Moreover, missile firing cannot be assumed detectable. Problems of such complexity haven't been treated yet in the frame of\ud classical differential game theory. In this paper a prototype Pilot Advisory\ud System (PADS), designed to solve the problems facing the pilot in such an\ud engagement, is described. PADS proposed to be an expert System, which operates in real--time and has a "knowledge base" incorporating differential game concepts and solution elements. PADS simultaneously evalua.tes potential success with the respective risks and advises the pilot when to fire his missile and when to start an evasive maneuver. This advisory system can guarantee survival when so desired by the pilot. but in most situations it maximizes the probability of victory with an accepted level of' risk

Views of the Chiral Magnetic Effect

My personal views of the Chiral Magnetic Effect are presented, which starts with a story about how we came up with the electric-current formula and continues to unsettled subtleties in the formula. There are desirable features in the formula of the Chiral Magnetic Effect but some considerations would lead us to even more questions than elucidations. The interpretation of the produced current is indeed very non-trivial and it involves a lot of confusions that have not been resolved.Comment: 19 pages, no figure; typos corrected, references significantly updated, to appear in Lect.

Phytochemical screening, isolation of coumarins and examining bioactivity of Prangos platychlaena Boiss. plant IN Iraq

The Prangos platychlaena Boiss. a wild plant belonging to the Apiaceae family, is a native plant of Kurdistan-Iraq. The roots, leaves, stem and flowers of the plant were collected in the Halgurd mountain of the Kurdistan region of Iraq, and extracted by petroleum ether, ethanol and water to obtain the crude extracts. Our results showed that the plant contains different phytochemicals that are distributed unequally in different parts. The chromatography technique was used for the isolation and purification of three coumarins (5,8-dimethoxy psoralen, 5-methoxy psoralen and 8-methoxy psoralen) from the parts of the flower, all compounds are new among the Prangos species. The extracts of different plant parts and isolated compounds showed anti-oxidant and anti-microbial activities against pathogenic bacteria and yeasts. These findings suggested that this plant, specially their leaves and flowers can be used for the treatment of some diseases in the future

Holographic two dimensional QCD and Chern-Simons term

We present a holographic realization of large Nc massless QCD in two dimensions using a D2/D8 brane construction. The flavor axial anomaly is dual to a three dimensional Chern-Simons term which turns out to be of leading order, and it affects the meson spectrum and holographic renormalization in crucial ways. The massless flavor bosons that exist in the spectrum are found to decouple from the heavier mesons, in agreement with the general lore of non-Abelian bosonization. We also show that an external dynamical photon acquires a mass through the three dimensional Chern-Simons term as expected from the Schwinger mechanism. Massless two dimensional QCD at large Nc exhibits anti-vector-meson dominance due to the axial anomaly.Comment: 22 page

Gross-Neveu Models, Nonlinear Dirac Equations, Surfaces and Strings

Recent studies of the thermodynamic phase diagrams of the Gross-Neveu model (GN2), and its chiral cousin, the NJL2 model, have shown that there are phases with inhomogeneous crystalline condensates. These (static) condensates can be found analytically because the relevant Hartree-Fock and gap equations can be reduced to the nonlinear Schr\"odinger equation, whose deformations are governed by the mKdV and AKNS integrable hierarchies, respectively. Recently, Thies et al have shown that time-dependent Hartree-Fock solutions describing baryon scattering in the massless GN2 model satisfy the Sinh-Gordon equation, and can be mapped directly to classical string solutions in AdS3. Here we propose a geometric perspective for this result, based on the generalized Weierstrass spinor representation for the embedding of 2d surfaces into 3d spaces, which explains why these well-known integrable systems underlie these various Gross-Neveu gap equations, and why there should be a connection to classical string theory solutions. This geometric viewpoint may be useful for higher dimensional models, where the relevant integrable hierarchies include the Davey-Stewartson and Novikov-Veselov systems.Comment: 27 pages, 1 figur
