摘要:The speed of light has been repeatedly measured considering the time a photon spends travelling from an initial point to another and then coming back to the initial point, the so called two-way speed of light. Experiments aiming to measure the speed of light when it travels stric...

摘要:The propagation of ion-acoustic waves (IAWs) in a collisionless unmagnetized selfgravitating degenerate quantum plasma system (SG-DQPS) has been studied theoretically for the first time. A nonlinear Schrödinger equation is derived by using the reductive perturbation method t...

摘要:The main features of resonance in scattering are described and resonances are determined on the basis of the theory of collisions in a two-body system, as well as resonances emerging as a result of collisions in a few-body system. Regularities in the emergence of such resonances ...

摘要:The existence of the Aharonov-Bohm (A − B) effect with its associated U(1)-bundle A−B, and the uniqueness -up to homotopy- of a continuous function S2 ! C , induce a unique map -up to isomorphism- between the Hopf bundles with zero and unit Chern number, respectively 0 : S1 ...

摘要:We report here for the first time the possible presence of organic compounds in Sadiya (LL5) ordinary chondrite using micro-Raman and infrared spectroscopic technique. The micro-Raman spectrum exhibits the diamond and graphite peaks correspondingly at 1331 cm-1, 1349 cm-1 an...

摘要:Participation in physical activity (PA) builds self-efficacy required for adolescent development. This study investigates the extent of physical activity among the adolescent students and its influence on their physical activity self-efficacy (PSE) in two developing societie...

摘要:The evaluation of the physical parameters or e ects|such as the luminosity function (LF) or the photometric maximum (PM)|for galaxies is routinely modeled by their spectroscopic redshift. Here, we model LF and PM for galaxies by the photometric redshift as given by the Spitzer Wi...

摘要:The global financial crisis and the outbreak of the banking crisis in the Eurozone have had a great impact on the macro economy. The influence of macroeconomic uncertainty on monetary policy has become the focus of scholars' research. Based on data from 2011 to 2016, public infor...

摘要:Careful monitoring of the quality and quantity of water resources plays a significant role in modern environmental management. Thus, to achieve this aim, the quantitative and qualitative parameters of water resources should be measured and controlled with a desirable accuracy. Ho...

摘要:Pedolological characterization was done in Dodoma Capital City District, Tanzania. Three soil profiles developed from in-situ weathering of granic rocks and designated as HIS-P1, HISP2 and HIS-P3 were described. Fifteen samples were taken from genetic horizons and analyzed for ph...
