AbstractAbstract
[en] The methods used so far for quoting the exclusion limit that a future experiment will be able to set involve some degree of arbitrariness. A general validity procedure is proposed, which should settle the controversy. (orig.)

AbstractAbstract
[en] The results of the radiolysis of aqueous solutions of thiamine (vitamin B1) are presented. The yields for decomposition of thiamine and the production of radiolytic products were determined. The G values decrease as the dose increases. Some radiolytic products were identified. Decomposition of thiamine was slightly dependent on the presence of oxygen and on the pH of the solution. At pH 4.4, with a concentration of 2.5x10-4 mol L-1 of thiamine in an oxygen free aqueous solution, the G0 value for decomposition is 5.0

AbstractAbstract
[en] Minimal supersymmetric models can generate a large τ sneutrino vacuum expectation value (VEV). However, neutrino mass limits constrain the sneutrino VEV to be small (left-angle ντ right-angle approx-lt 10 GeV) unless the gaugino mass is unnaturally large (M approx-gt 1 TeV) or the Higgs-boson-Higgs-boson coupling is small (|μ|approx-lt 10 GeV). We show that the latter case is now ruled out by CERN LEP data and gluino mass limits

AbstractAbstract
[en] The threshold for the 34S(p, n)34Cl reaction has been measured and the reaction Q-value determined to be -6274.27 +- 0.56 keV. From this the Q-value for the 34Cl superallowed β-decay has been deduced as 4469.8 +- 0.6 keV, which is in good agreement with other recent measurements. Using the presently accepted value for the 34Cl half-life, the ft value has been calculated to be 3085.1 +- 3.8 s. (Auth.)

AbstractAbstract
[en] To facilitate pulse radiolytic oxidative studies in highly acidic H2SO4 solutions (Ho< O), prior knowledge of three experimental parameters are desirable. These are (i) G(ox), i.e. the total yield of oxidizing radicals SO4 and OH; (ii) G(H) and (iii) maximum solubility of O2 used for preferential scavenging of the sole reducing radical (H). The results indicate almost constant linear increase in G(ox) by 0.028 μM J-1 Ho-1 below pH O, and non-linear rapid reduction in [O2] from 1.25 mM at Ho 0 to 0.31 mM at Ho - 7.0. (author)

AbstractAbstract
[en] The ground state energy of a system of identical neutral bosons bound to each other by gravitational forces is investigated. An analysis of the Schroedinger equation shows that for an arbitrary number of particles N the lower limit of the energy of the system can be determined by solving the purely geometric problem of the maximum for the sum of the cosines for all angles Θj,k,l formewd by all triplets of particles j, k, l which can be combined from the N particles of the system. In this way the purely geometrical lower limit is found for the energy of a gravitating boson system for N=3, 4, 6, 8, 12 and 20 and also in the limit for N→∞

AbstractAbstract
[en] The radiation-chemical processes in aqueous solutions of dichromates, isopolymolybdates and isopolytungstates have been studied. The radiation reduction of Cr(VI) to Cr(III), Mo(VI) to Mo(V) and W(VI) to W(V) takes place. Molybdenum and tungsten blues are the products of the last two processes in acid solutions. The yields of reduction decrease significantly with the increase of pH. The mechanisms of the processes have been discussed. The photochemical reduction of Mo(VI) and W(VI) for the production of corresponding 5-valent states have been used to the study of their electron scavenging efficiencies. It has been shown that these efficiencies decrease in the order: Mo(V) > W(V) > Cr(VI) > Mo(VI) > W(VI). (author)

AbstractAbstract
[en] We explore the parameter space of the MSSM (Minimal Supersymmetric extension of the Standard Model) with explicit CP-violating (CPV) phases by means of a Markov Chain Monte Carlo analysis, imposing constraints from direct Higgs and SUSY searches at colliders, B-physics, EDM (Electric Dipole Moment) measurements, and the relic density of dark matter. We find that over most of the parameter space, large phases are compatible with experimental data. We present likelihood maps of the CPV-MSSM, concentrating in particular on quantities relevant for the neutralino relic density. (authors)
