Formation of Innovation Educational Environment at High School

The author, based on the achievements of a phycological–pedagogical science, researches in the sphere of pedagogy at high school and pedagogical innovations, makes discussions on the theoretical-methodological and practical issues the of formation of an innovative educational environment. The emphasis is made on the conditions promoting to the formation of an effective educational environment, the mechanisms required for its formation, need on planning and implementing the creative projects and a requirement on the didactical system with two-level content of training discipline

Hadron Production via e+e- Collisions with Initial State Radiation

A novel method of studying e+e- annihilation into hadrons using initial state radiation at e+e- colliders is described. After brief history of the method, its theoretical foundations are considered. Numerous experiments in which exclusive cross sections of e+e- annihilation into hadrons below the center-of-mass energy of 5 GeV have been measured are presented. Some applications of the results obtained to fundamental tests of the Standard Model are listed.Comment: 50 pages, 88 figures, accepted for publication in Rev. Mod. Phy

The Voice of Civil Society Organisations in Georgia's Climate Policy

Ambitious climate protection is a complex challenge and task for society as a whole which requires the interaction of a wide range of actors. Civil society organisations (CSOs) play a crucial role in shaping the national climate policy framework and its implementation. They are a constructive driving force in the transformation process, bringing the needs and interests of local people into national and international discourse. International agreements and national laws require their participation in environmental decision-making processes. But which opportunities do Georgian CSOs currently have to participate in national climate policy? This article analyses opportunities for and barriers to participation in climate political decision-making, for example during the update of Georgia's National Determined Contribution (NDC), and gives recommendations on how the involvement could be improved in the future

Hadronic Contributions to the Muon g−2g-2 and Low-Energy QCD

The contributions to the muon anomalous magnetic moment from hadronic vacuum polarization and from hadronic light-by-light scattering are reexamined within the frame work of chiral perturbation theory; the $1/N_c$-expansion; and the extended Nambu Jona-Lasinio model of low-energy QCD.Comment: 17 pages, CPT-93/P.2962, 4 figures available by request from the autho

SOME DIRECTIONS IN THE PROCESS OF EFFECTIVE TRAINING / TEACHING THE FOREIGN LANGUAGE

Nowadays, the country’s the educational system faces important innovations and challenges owing to the new programs offered. Hence, high schools should prepare teachers with professional competency which will be able to give effective lessons; to implement the student-oriented teaching process successfully at Georgian as well as at Non-Georgian schools in Samtskhe-Javakheti region, to manage the school environment and teaching/studying processes effectively. Effective use of a teaching method is one of the most important links in education of teachers. Teachers often find it difficult to distinguish methods and teaching activities. Teaching method is a teacher’s goal-seeking activity aimed at developing proper competency in students. While choosing teaching methods, teacher should define the lesson goal and the expected results – what he/she should know and what he/she can do. Course content as well as teaching methods depend on the results

ρ→4π\rho\to 4\pi DECAY

The decay modes $\rho^0 \to 2\pi^+ 2\pi^-$ and $\rho^0 \to 2\pi^0 \pi^+ \pi^-$ are considered in the framework of the low energy effective chiral Lagrangian. The obtained values of the decay widths $\Gamma(\rho^0\to 2 \pi^+ 2 \pi^-)=$ $(16 \pm 1){\rm keV}$ and $\Gamma(\rho^0\to 2 \pi^0 \pi^+ \pi^-)= (6.0 \pm 0.2)$keV do not contradict the existing upper limits and seem to be big enough for the corresponding processes to be observed in future high luminosity experiments.Comment: 6 pages, LaTeX, without figure.

Study of the radiation hardness of CsI(Tl) scintillation crystals

This paper is devoted to the study of a degradation of CsI(Tl)crystals scintillation characteristics under irradiation with gamma-quanta at the uniformly distributed absorbed dose up to 3700 rad. The sample set consisted of 25 crystals of 30 cm long having a truncated pyramid shape and 30 rectangular crystals of the same length. A large difference in the light output deterioration caused by the radiation was observed for the samples of the same shape. A substantial dependence of the average light output loss from the sample shape is seen as well. On the other hand, the crystals from the same ingot behave very similarly under irradiation

The hadronic vacuum polarization contribution to the muon g-2 in the quark-resonance model

The hadronic vacuum polarization contribution to the anomalous magnetic moment of the muon is parametrized by using the quark-resonance model formulated in \cite{QR}. In this context a recent prediction obtained within the ENJL model \cite{RAF} can be affected by two additional contributions: the next to leading corrections in the inverse cutoff expansion and the gluonic corrections. Motivated by the necessity of reaching a highly accurate theoretical prediction of the hadronic contribution to the muon g-2, we study in detail both the effects.Comment: 15 pages (Latex), 1 postscript figure appended, preprint LNF 94/031 (P), ROM2F 94/1

On One Type of Negative Sentence in the Original Text of “The Knight in the Panther’s Skin” and its English Translation

The paper analyzes occasional words with negative meaning, formed by means of particle-morphemoid არ ar “not”. These words are analyzed based on the examples from “The Knight in the Panther’s Skin”, an epic poem written by the famous 12th century Georgian poet Shota Rustaveli. As a result of the analysis, two groups have been distinguished: a. The words in question are used separately, without connection to the verb, negation is expressed lexically, absence is logically expressed positively, and, according to the proposition, the sentence is affirmative. b. The words under analysis are used as parts of the compound nominal predicate, the particle არ ar “not” is connected to the predicate centre of the sentence, and, according to the proposition, the sentence is negative. The above-mentioned distinction between the groups is also proved on the basis of the literal English translation of Rustaveli’s poem

A Pionic Hadron Explains the Muon Magnetic Moment Anomaly

A significant discrepancy exists between experiment and calculations of the muon's magnetic moment. We find that standard formulas for the hadronic vacuum polarization term have overlooked pionic states known to exist. Coulomb binding alone guarantees $\pi^+ \pi^-$ states that quantum mechanically mix with the $\rho$ meson. A simple 2-state mixing model explains the magnetic moment discrepancy for a mixing angle of order $\alpha \sim 10^{-2}$. The relevant physical state is predicted to give a tiny observable bump in the ratio R(s) of $e^+ e^-$ annihilation at a low energy not previously searched. The burden of proof is reversed for claims that conventional physics cannot explain the muon's anomalous moment.Comment: 14 pages, 2 figures, revised version, accepted for publication in Physics Letters
