Symmetry And The Order Of Events In Time: Description Of A Reversible Thermal Energy Converter Composed Of Negative Mass, Randy Wayne

Turkish Journal of Physics

In a previous paper [1], we analyzed the sequence of events that occurs in the time domain of a reversible cyclical thermal energy converter using the Gibbs equation and showed that even when there is no net change of entropy there is an asymmetrical order of quasi-static states along the time axis, when thermal energy is converted into mechanical pressure-volume work. The spontaneous evolution towards an equilibrium state, which is characterized by the unidirectional transport of entropy from the hot reservoir to the cold reservoir, is coincident with this asymmetrical order of events. In this paper, we \"mend\" the above …

Thermodynamic Properties Of The Noncommutative Black Hole In (Z = 3)-Horava-Lifshitz Gravity, Mourad Nach, Khadija Bilal, My Brahim Sedra, Abderrahman El Boukili

Turkish Journal of Physics

In this work, we investigate the effects of noncommutative spaces on the Horava-Lifshitz black hole. We construct the black hole solutions in the noncommutative space of (z = 3)-Horava-Lifshitz gravity. We calculate the horizon and the thermodynamic properties such as the Hawking temperature, the ADM-Mass, and entropy, which reduce to their commutative limits when the noncommutativity parameter tends to zero.

One Proton Emission With Structural Effects In Medium Mass Nuclei, Chandrasekaran Anu Radha, Velayudham Ramasubramanian

Turkish Journal of Physics

In this work proton emission from deformed nuclei is discussed with the quadrupole deformation values. The deformation is investigated using potential energy surface plots. The identified proton emitters are found to have odd Z since the unpaired proton is less bound, and they are readily available for emission. Using the exotic decay model to the medium mass nuclei, the new proton emitters are analyzed with the inclusion of centrifugal barrier. The proton decay half-lives are calculated and compared with literature values. A discussion pertaining to single proton emission with structural effect will be a pivotal point in our study.

Spin Assignment And Behavior Of Superdeformed Bands In A\\Sim 150 Mass Region, Ali Khalaf, Manal Sirag, Mahmoud Taha

Turkish Journal of Physics

The smoothed experimental dynamical moment of inertia J^{(2)} values were fitted with a theoretical version using the Harris three parameter formula in even powers of angular frequency \omega, derived for results from the cranking model. The expansion parameters were adjusted by using a computer simulated search program. The best expansion parameters from the fit were used to assign the spins of the superdeformed (SD) rotational bands (RB) by integrating the calculated J^{(2)}. The data set includes 23 RB's in 11 SD nuclei, which show no evidence of either irregular behavior near the bottom of the bands or abrupt angular momentum …

The Nonrelativistic Molecular Tietz Potential, Hossein Nikoofard, Elham Maghsoodi, Saber Zarrinkamar, Mohsen Farhadi, Hassan Hassanabadi

Turkish Journal of Physics

We solve the 3-dimensional Schrödinger equation under the Tietz potential by an approximate analytical scheme. A Pekeris-type approximation and the Nikiforov--Uvarov technique are used in the calculations to report the arbitrary-state eigenfunctions and eigenvalues and we calculate some useful expectation values of the Tietz potential using the Hellmann-Feynman theorem and obtain the oscillator strength.

The results, after application of proper fits, can be used in the study of relativistic spinless particles in various branches of physics such as cosmology and theoretical nuclear physics including meson spectroscopy.

Empirical Rule For The Pair Break Mechanism In Three-Quasiparticle Rotational Bands, Sukhjeet Singh Dhindsa, Sushil Kumar, Jatinder Kumar Sharma

Turkish Journal of Physics

An empirical rule on the basis of odd-even mass difference is suggested for the breaking of a proton pair or a neutron pair in odd-A nuclei to form a lower lying 3-quasiparticle state. If \Delta_p is smaller than \Delta_n, the proton pair breaks; on the other hand, if \Delta_n is smaller than \Delta_p, the neutron pair breaks down and forms a lower lying 3-quasiparticle state in an odd-A nuclide. This rule appears not only purely based on the proton paring/neutron pairing energy balancing condition but also on particular excitation energy, which is \ge 1 MeV in the case of the …

Investigation Of Dominant States In The Collisions Of Ar Vii And Kr Xxiv With H_2 And He Targets, Abdel Aziz Habib, Alaa Abo Zalam, Hassan Ramadan

Turkish Journal of Physics

In thermal plasma, the ion--atom collisions proceed most probably through resonance processes. One of the important processes is the resonant transfer excitation followed by emission of X-rays (RTEX), which causes self-cooling for plasma. In addition, it is identical to the dielectronic recombination (DR) in electron-ion collisions. The present work deals with the calculation of DR cross-sections (\sigma^{DR}s) and DR rate coefficients (\alpha^{DR}s) as well as RTEX cross-sections (\sigma^{RTEX}s) for Mg-like ions [Ar^{6+} and Kr^{24+}] with L-shell and K-shell excitation for \Deltan = 0 and \Delta n \neq 0. Comparison between the present results and other calculations for the rates are …

Study Of Zone Center Phonons In Wolframite Znwo_4, Ruby Jindal, Murari Mohan Sinha, Hem Chandra Gupta

Turkish Journal of Physics

A short-range force constant model was applied to investigate the phonons in wolframite ZnWO_4 crystals in their monoclinic phase having space group P2/c and symmetry C_{2h}. The normal symmetry coordinates for the monoclinic wolframite were computed. The zone center phonons were calculated by using 8 stretching and 6 bending force constants. The calculated results are in very good agreement with the observed ones. The infrared frequencies were assigned for the first time. The potential energy distribution was also investigated for determining the significance of the contribution from each force constant toward the Raman and infrared wavenumbers.

A Simple Method To Extract The Parameters Of The Single-Diode Model Of A Pv System, Ahmed A. El Tayyan

Turkish Journal of Physics

This article suggests a simple method of modeling and simulation of photovoltaic systems. The main goal is to find the parameters (I_{ph}, I_o, R_s, R_{sh}, and a) of the single-diode model by adjusting the P-V curve and/or I-V curve at parameters provided by the manufacturer specification sheets (I_{sc}, V_{oc}, I_{mp}, and V_{mp}). An empirical model is incorporated into the single-diode model in order to remove its implicit nature and to ease the calculations. Calculations using this method can be extended to generate the I-V curves at temperatures and irradiances other than the standard test condition (STC)

Study Of Solid-State Stability Of The Zoto Binary System, Sandeep A. Waghuley

Turkish Journal of Physics

The ZOTO binary system contains different compositions of zinc oxide (ZnO) and tin oxide (SnO_2). These are important semiconductors and have been intensively explored for various applications. SnO_2, ZnO, and different mole ratios (70:30, 40:60, 30:70, and 20:80 SnO_2:ZnO) of the ZOTO system were prepared through proper thermal treatment in powder form. The comparative solid-state stability was investigated using thermogravimetric and differential thermal analysis (TG-DTA). The stability study showed that the SnO_2 material absorbs much lower heat (Ea = -72.06 kJ/g mol) compared with ZnO and their compositions. Thus the SnO_2 material shows stability at near room temperature operation. The …

Improved Hilbert Moment Thermal Qcd Sum Rules For B_S Meson And Stability With Respect To Moment Parameter, Elşen Veli̇, Gülşah Kaya, Arzu Türkan, Eni̇s Yazici

Turkish Journal of Physics

In this paper, we deal with the temperature dependence of the leptonic decay constant and mass of B_s meson in the framework of the Hilbert moment QCD sum rule. In our calculations, we improve the thermal QCD sum rules, taking into account the thermal spectral density and the perturbative 2-loop order corrections to the correlation function. Moreover, we investigate the stability of the results with respect to the Hilbert moment parameter. Our numerical calculations demonstrate that the mass and decay constant are insensitive to the variation of temperature up to T \cong 100 MeV; however, after this value, they start …

Turkish Journal of Physics

A novel technique is presented for the assessment of the track response of the detector CR-39 to alpha particles by photothermal deflection spectroscopy and image analysis. The 2 new techniques can be implemented to CR-39 as in situ measurements. The proposed techniques offer the possibility of monitoring nuclear radiation directly. Photothermal deflection is described to detect the change in the thermal and optical properties of the track nuclear detector CR-39 when irradiated to alpha particles. In situ image analysis of the photothermal deflection spot is presented to assess the detection of the CR-39 of any nuclear particle or radiation instantaneously.

Analyses Of Elastically Scattered Charged Pions From Calcium Isotopes And The ^{48}Ca-^{54}Fe Isotone At 180 Mev, Zuhair Fayyad Mahmoud Shehadeh

Turkish Journal of Physics

The elastic scattering of 180 MeV positively and negatively charged pions, incident on a set of calcium isotopes and the isotone ^{48}Ca - ^{54}Fe, has been analyzed within the framework of a recently updated simple local optical potential. This potential, particularly at the tail region, has been originally determined from available phase shifts using inverse scattering theory and the Klein--Gordon equation as a guide. The analysis is carried out with and without considering the squared potential term in the Klein-Gordon equation. Coulomb effects are accounted for by implementing Stricker's prescription. The numerical results for the angular distributions with isotopic and …
