We investigate the singlet, triplet and colour average heavy quark free energies in SU (2) pure gauge theory at various temperatures T. We focus on the long distance behaviour of the free energies, studying in particular the temperature dependence of the string tension and the screening masses. The results are qualitatively similar to the SU (3) scenario, except near the critical temperature Tc...

We study systems of particles on a line which have a maximum, are locally finite and evolve with independent increments. “Quasistationary states” are defined as probability measures, on the σalgebra generated by the gap variables, for which joint distribution of gaps between particles is invariant under the time evolution. Examples are provided by Poisson processes with densities of the form ρ(...

The 6Li(t , 3He)6He charge-exchange reaction leading to the weakly-bound nucleus 6He has been studied at 336 MeV. Beyond the strong peaks for the known ground state (Jπ = 0+) and first excited state (Jπ = 2+, Ex = 1.8 MeV), a broad asymmetric structure around Ex ∼ 5 MeV has been observed. The angular distribution of this structure exhibits the dominance of a1L= 1 transition, indicating the exis...

The emitted radiation is usually in the visible region and at right angles to the incident radiation; only visible rarely when absorbed radiation is of visible high energy (short wavelength) in U.V region is the emitted radiation in U.V region. Molecules at room temperature are in ground electronic state. It absorbs energy and goes to excited electronic state. The groups of lines represent vibr...

Hybrid Electric Vehicles (HEVs) are driven by two energy convertors, i.e., an Internal Combustion (IC) engine and an electric machine. To make powertrain of HEV as efficient as possible, proper management of the energy elements is essential. This task is completed by HEV controller, which splits power between the IC engine and Electric Motor (EM). In this paper, a Genetic-Fuzzy control strategy...

The internal s-electron polarization in the ground state of a Friedel-Anderson and a Kondo impurity is calculated. The Wilson basis with exponentially fine energies close to the Fermi level is used and expressed in terms of free electron waves with linear energy-momentum dispersion. It is found that in the singlet state the magnetic moment of the d-electron is screened by an s-electron cloud. T...

Angular distributions of the 14–17 MeV g rays from the Li~p ,g) reaction at Ep5450, 402, and 80 keV were measured at 0°<u lab<135°, using a BGO detector and a 28-mg/cm 2 LiF target. The angular distributions at Ep5450 and 402 keV agree with the previous results by Mainsbridge; at Ep580 keV the ground-state transition is anisotropic on the order of 20%, confirming recent results by Chasteler et al.

Non-resonant direct p-and d-wave neutron capture by 12 C Abstract Discrete γ-rays from the neutron capture state of 13 C to its low-lying bound states have been measured using pulsed neutrons at E n = 550 keV. The partial capture cross sections have been determined to be 1.7±0.5, 24.2±1.0, 2.0±0.4 and 1.0±0.4 µb for the ground (J π = 1/2 −), first (J π = 1/2 +), second (J π = 3/2 −) and third (...

Gas hydrates attracted worldwide attention due to their potential as huge energy resource in the recent decades. Effective parameters which influence the formation of hydrates are high pressure, low temperature and water presence. HYSYS software is one of the major simulators which are widely used in the chemical and thermodynamic processes. This research was conducted to simulate gas hydrate f...

background: the performance and parasitology of semi-intensively managed west african dwarf (wad) lambs were evaluated following exposure to gastrointestinal helminth infected paddock and varied protein-energy feeds. methods: twenty four lambs obtained from the department of animal breeding and genetics and brought to directorate of university farm (dufarm) of federal university of agriculture ...
