A general analysis of polarization phenomena for coherent pion electroproduction on deuterons is presented. The spin and isospin structures of the gamma* + d --> d + P-0 amplitudes (where gamma* is a virtual photon) are established and relationships between meson electroproduction on deuterons and on nucleons are given in the framework of the impulse approximation. The reaction e + d --> e + d + pi(0) is investigated in detail, for a relatively large value of momentum transfer, 0.5 GeV2 less than or equal to -k(2) less than or equal to 2 GeV2, both at threshold and in the region of Delta-isobar excitation. Special attention is devoted to the sensitivity of different contributions to the exclusive cross section for d(e, epi(0))d, as the gamma*piomega form factor or the NN-potential. The predicted k(2)-dependence of the cross section agrees well with the available experimental data. (C) 2002 Elsevier Science (USA).

Forward energy flow, central charged-particle multiplicities, and pseudorapidity gaps in W and Z boson events from pp collisions at root s=7 TeV
Chatrchyan, S.; et. al. (Springer Science and Business Media LLC, 2012-01-01)
A study of forward energy flow and central charged-particle multiplicity in events with W and Z bosons decaying into leptons is presented. The analysis uses a sample of 7 TeV pp collisions, corresponding to an integrated luminosity of 36 pb(-1), recorded by the CMS experiment at the LHC. The observed forward energy depositions, their correlations, and the central charged-particle multiplicities are not well described by the available non-diffractive soft-hadron production models. A study of about 300 events...
Pulse frequency changes of 1E 2259+586 and the binary interpretation
Baykal, Altan (1996-03-20)
Pulse frequencies from the archival ROSAT observations of 1E 2259+586 are presented. A short-term spin-up episode superposed on the secular spin-down trend is observed. Combining the previously published pulse frequencies, we estimate the variance of the angular velocity over a 15 yr span of observations. The level of fluctuations in angular velocity is similar to that of established accreting binary neutron stars. These results favor accretion by a neutron star from a very low mass companion as the source ...
Transient and steady state photoelectronic analysis in TlInSe2 crystals
QASRAWI, ATEF FAYEZ HASAN; Hasanlı, Nızamı (Elsevier BV, 2011-08-01)
The temperature and illumination effects on the transient and steady state photoconductivities of TlInSe2 crystals have been studied. Namely, two recombination centres located at 234 and at 94 meV and one trap center located at 173 meV were determined from the temperature-dependent steady state and transient photoconductivities, respectively. The illumination dependence of photoconductivity indicated the domination of sublinear and supralinear recombination mechanisms above and below 160 K, respectively. Th...
Socio-Spatial Politics of Otherness: The Desire to Construct a Counterhegemony
Yoltay, Ece (2019-03-01)
This study is based on an empirical research to understand the production of nongovernmental spatial practices and representations with a counterformation to an authority, as well as an ontological discussion on the relations between public space and power. In this respect, the study is constructed on an alternative spatial reading of counterspaces (LGBTI-friendly spaces, political spaces, and resistance spaces) in the capital of Turkey, Ankara, benefiting from Henri Lefebvre’s theory on the production of s...
Numerical and experimental investigation of tubeaxial fan noise
Bodur, Ahmet; Çalışkan, Mehmet; Department of Mechanical Engineering (2014)
In this study, the noise characteristic of a tube axial fan is investigated numerically and experimentally. The effects of blockage plate in front of the tube axial fan on the tube axial fan noise level are experimentally investigated. A computational aero-acoustic method is used to predict the flow induced fan noise. This method couples a flow solver and a wave equation solver. Unsteady flow analysis is performed with URANS (Unsteady Reynolds Average Navier Stokes Equation) method while acoustics radiation...
