The new SPASCHARM experiment for systematic studies of polarization phenomena in strong interactions is under construction now at IHEP, Protvino. The technical beam runs for the experiment first ...stage are planned for the Fall 2016 and Spring 2017. At this stage, the polarization measurements will be carried out with unpolarized hadronic beams of various compositions (π±, K±, p, antiprotons), using the polarized target. The universal large acceptance experimental set-up is capable detecting and identification most charged and neutral particles and reconstructing a large number of resonances produced in beam interactions at polarized proton target, and later on at the second stage, in collisions of polarized proton and antiproton beams with fixed targets of various materials. The large acceptance and wide data acquisition bandwidth would provide the capabilities for simultaneous data accumulation for a number of physics analyses from the measurements of single-spin asymmetries in inclusive and exclusive reactions to reconstructions of final state hyperon polarizations and spin density matrix elements for vector mesons in a wide range of kinematic variables (pT, xF).
A new experiment SPASCHARM for systematic study of polarization phenomena in inclusive and exclusive hadronic reactions is currently under commissioning at IHEP. The universal experimental setup will ...detect dozens of various resonances and stable particles produced in collisions of unpolarized beams with the polarized target, and at the next stage, using polarized beams. At the first stage with polarized target, the final states composed of light quarks (u, d, s) will be reconstructed. Hyperon polarization and spin density matrix elements of the vector mesons will be measured along with the single-spin asymmetries. The 2π-acceptance in azimuth, which is extremely useful for reduction of systematic errors in measurements of spin observables, will be implemented in the experiment. The solid angle acceptance of the setup, Δθ≈250 mrad vertically and 350 mrad horizontally in the beam fragmentation region, covers a wide range of kinematic variables pT and xF. This provides the opportunity for separating dependences on these two variables which is usually not possible in the setups with a small solid angle acceptance. Unlike some previous polarization experiments, the SPASCHARM will be able to simultaneously accumulate and record data on the both, charged and neutral particle production.
Self-regulated learning (SRL) is viewed as an important aspect of student academic performance and achievement. Over the past decades, the concept of SRL has been heavily researched, with many ...educational psychologists proposing theoretical models and setting up studies to test the theories and provide pragmatic information about SRL. The aim of this review was to analyze different models of SRL. To achieve this goal, three models of SRL developed by Zimmerman, Pintrich and Efklides were presented. All of the models had empirical evidence supporting the validity of some of their main aspects. As developing their models, both Pintrich and Zimmerman, and partly Efklides; drew on the same background theory and their models reflected Bandura’s 1986 Social Cognitive Theory, underlining social foundations of thinking and behavior. The terminology also varied from one model to another, but all the authors assumed SRL to proceed from a preparatory or preliminary phase, through actual performance or task completion phase, to an appraisal or adaptation one.
Several centuries have passed, since the birth of traditional educational paradigm comprised of knowledge, abilities, and skills. The world has also changed, and pedagogical systems have remained ...mostly the same as those at the beginning of their formation, and have also become inadequate for time challenges. This is manifested in the fact that post-industrial or new information society of the 21st century facing the problem of lack of people, who would be able to work in new conditions right after the graduation. The situation when a specialist with a diploma has a finite amount of knowledge in the absence of ability to use it and replenish, becomes a deterrent to the development of the productive forces of society. This is the reason for the appeal of the European, and consequently, the Russian education to the competency building approach. Traditionally, the goals of education were determined by the set of knowledge, abilities, and skills that a graduate must possess. Today, this approach has been proven inadequate. Society needs graduates ready to run active life and capable of solving vital and professional problems occurring. This mainly depends both on received knowledge, abilities, and skills, and also on some additional qualities implying “competence” and “adequacy” that have more in common with modern education goals. To this end, in the experimental part of the study, a model for the formation of professional competencies of university students during the process of implementation of new educational standards was presented.
In this report the calculations of aerosol concentrations on the basis of a physical model of the distribution of suspended particles in the turbulent atmosphere taking into account non linear ...atmospheric effects are given. As a result of the non-linear interaction the spectra of the main atmospheric parameters (temperature, pressure, density, zonal and meridional winds) are obtained. Obtained values of these atmospheric parameters were used for making of space distribution of solar radiation attenuation by aerosol at the atmosphere. The calculations showed that spaced variations are different for various periods.
The first stage of the proposed polarization program SPASCHARM includes the measurements of the single-spin asymmetry (SSA) in exclusive and inclusive reactions with production of stable hadrons and ...the light meson and baryon resonances.In this study we foresee of using the variety of the unpolarized beams (pions, kaons, protons and antiprotons) in the energy range of 30-60 GeV. The polarized proton and deuteron targets will be used for revealing the flavor and isotopic spin dependencies of the polarization phenomena. The neutral and charged particles in the final state will be detected.
