[en] Interacting gluon model providing a dynamical input for statistical models of strong interactions is formulated both for hadronic and nuclear collisions. It gives also its own independent predictions for such observables as inelasticity distributions, leading particle spectra and energy density distributions. They are calculated and compared with existing data. Both analytical and purely numerical versions of the model are presented and discussed. 96 refs., 16 figs., 7 tabs. (author)

[en] The inelasticity of hadron-carbon collisions for energies exceeding 100 TeV is estimated from the carbon-emulsion chamber data at Pamirs to be < K_C> = 0.65 ± 0.08. When combined with data on hadron-lead collisions taken in the same energy range it results in the K ∼ A^0.086 mass number dependence of inelasticity. The evaluated partial inelasticity for secondary (ν > 1) interactions, K_ν>1 ≅ 0.2, suggests that most of the energy is lost in the first interaction

[en] We present calculation of influence caused by nucleon Fermi motion on the parton distributions in nuclei. Our approach is based on the model where momenta of valence partons have some primordial distribution inside the hadron at rest, which is either provided by a statistical considerations or calculated using spherically symmetric Gaussian distribution with a width derived from the Heisenberg uncertainty relation. The sea parton contribution emerges from the similar Gaussian distribution with a width dictated by the presence of virtual pions in hadron. We show that the influence of Fermi motion changes substantially the nucleonic structure function inside the nucleus in the right direction and therefore should be considered seriously in all attempts devoted to explain the experimentally observed EMC effect for x_Bj > 0.1

[en] We argue that the so called long flying component (LFC) observed in some cosmic ray experiments are yet another manifestation of Levy distributions (with index q = 1.3), this time of the distribution observation probability of the depths of starting points of cascades. It means that LFC is governed by the so called long-tail Levy-like anomalous superdiffusion, a phenomenon frequently encountered in Nature. Its connection with the so called Tsallis's statistics is also briefly discussed

[en] The idea of formation zone as introduced to the hadronic multiproduction by Stodolsky has been applied to the description of the large psub(T) production on nuclei. It was found that the formation zone concept has to be supplemented by additional assumptions to be in agreement with present experimental data. (Auth.)

[en] 40 patients, aged 7-50 years, were examined. Occlusal films, pantomography, survey skull X-rays, tomography of the facio-cranium as well as CT examinations were performed. In benign processes the occlusal X-rays with pantomography for evaluation of the hard palate osseous structure and adjacent structures were useful. The estimate the character and extent of malignant neoplasmatic changes the pantomogram and CT examinations should be carried out. (author)
