    Opis:
    The derivation of the virial theorem is presented both in classical and quantum mechanical approach. The kinetic energy and potential energy of the mechanical energy is converted to each other due to the virial theorem. Some of the different potentials are considered. For some of these potentials, the wavefunctions and energy eigenvalues of the Schrödinger Equation are derived.

    Opis:
    The aim of this work is to investigate the influence of the Geant4 parameters on the range and the depth-dose distribution (Bragg curve) of proton beams with incident energies of 90, 150 and 230 MeV injected upon a water medium, using the Geant4 simulation package. The simulated Bragg peak ranges and the depth-dose profiles have been compared with the ones obtained from the National Institute of Standards and Technology and the experiments, respectively. It has been seen that the Geant4 parameters, such as the step size and production cuts, under study have non-negligible effects on the range and the depth-dose distribution of incident proton energies of interest, especially at 150 and 230 MeV.

    Opis:
    We investigated the germination requirements of Androsace villosa L. (Hairy Androsace), which spreads on limestone or granite screes or ledges of rocky or turfy slopes and hilltops of the alpine zone. With seeds collected from Uludag Mt. (Bursa, Turkey, 2200–2300 m a.s.l.), germination was studied in fresh seeds, seeds subjected to short-time moist chilling (15 d, +4°C), to GA3 (100, 150 and 250 ppm), and to chilling plus GA3. The hormone and moist chilling treatments were carried out in continuous darkness (20°C) and under a 12 h photoperiod at 20/10°C. Seeds maintained in darkness gave higher germination percentages than seeds maintained under a photoperiod. Germination rates rose to 90–97% with 100–250 ppm GA3 and short-time moist chilling in continuous darkness (20°C). Seeds germinated rapidly under a combination of GA3 and short-time moist chilling in continuous darkness, generally giving the lowest mean germination times (4.4–5.0 d) among the treatments.

    Opis:
    In this study, the medical radioisotope production performance of a conceptual accelerator-driven system is investigated. Lead-bismuth eutectic is used as target material. The fuel core of the considered accelerator-driven system is divided into ten subzones, loaded with uranium carbide and various isotopes (isotopes of copper, gold, cobalt, holmium, rhenium, scandium, and thulium) and cooled with light water. As is known, light water is an effective moderator of neutrons as well as a good coolant. The fuel and the isotopes are separately placed as cylindrical rods with a cladding of carbon composite. The volume fractions of fuel, isotope, cladding and coolant are selected as 25%, 35%, 10% and 30%, respectively. The copper rods are placed into the first five subzones due to the fact that copper isotopes have low capture cross-section. In the case of the each radioisotope production, one of the other considered isotopes that have higher capture cross-section are placed into the following five subzones for optimization of fission, fissile breeding and radioisotope production. The graphite zone is located around the fuel core to reflect the escaping neutrons. Boron carbide (B₄C) is used as shielding material. In order to produce more neutrons (about 25-30 neutrons per 1 GeV proton), the target is irradiated with a continuous beam of 1 GeV protons. All neutronic computations have been performed with the high-energy Monte Carlo N-Particle Transport Code using the LA150 data library. The neutronic results obtained from these calculations show that the examined accelerator-driven system has a high neutronic capability, in terms of production of thermal power, fissile fuels, and medical radioisotopes.
