Measurement of the - mixing angle in and beams with GAMS- Setup
The results of mixing angle measurement for , mesons generated
in charge exchange reactions with and beams are preseneted.
When the , mesons are described in nonstrange(NS)--strange(S)
quark basis the and beams allow to study and
parts of the meson wave function. The cross section ratio at
(GeV/c) in the beam is , results in mixing angle . For
beam the ratio is . It was found that
gluonium content in is . The
experiment was carried out with GAMS-4 Setup.Comment: 6 pages, 4 figures, 1 table, to be submitted in European physical

Systematics of states of mental maladaptation in students
The objective: to specify clinical, psychopathological and pathopsychological manifestations of psychological maladaptation in the students. A total clinical-anamnestic, clinical-psychopathological and psychodiagnostic examination was carried out for 412 students of the KhNMU with an average age of 19.5 ± 2.5 years, 147 men and 265 women. Based on the data of the analysis of the levels of maladaptation, we allocated three groups of students:
Group 1 - low level of maladaptation – 46.0 ± 2.1% of the surveyed people, group 2 - moderate level of maladaptation 37.6 ± 2.1%, group 3 - high level of maladaptation 16.4 ± 1.6%. In the course of the work, the phenomenology of the mental state of students was conducted. Maladaptive conditions were determined by a decrease in mental health, exhaustion of attention, decreased productivity intellectual activity, irritability, hyperesthesia, anxiety, painful decline in mood, asthenia, low self-esteem, self-doubt, high levels of severity asthenic state and neuro-psychic tension

On the methodics of mathematical modelling of pollution of hydrolithosphere by petroleum products (exemplified by Kursk oil terminal)
A potential threat of pollution of hydrolithosphere with petroleum and its products due to accidental and technological leaks on a certain industrial object has been analyzed. The author's method of mathematical modelling is described that allows to perform an adequate dynamic modelling of a petroleum products lens in an aquifer. Execution of the resulting model allows to forecast behavior of petroleum products in the conditions of a real geological and hydro-geological cross-sectio
Carst marble on Tyrnyauz deposit
The karst of marbles is considered as the least studied type of karst. Here we have pinpointed the karst area of the ore field of the Tyrnyauz deposit. Lithological and petrographic characteristics of the skarned marbles of Tyrnyauz are given, their chemical activity is determined. Tectonogenic fissure-karst drainage system of the deposit is analyzed. The main factors of karst formation have been determined and the development of the karst marbles of the Tyrnyauz ore field at various depths is predicte
The forecast of changes in the natural and technogenic conditions of the built-up territory on the example of the "Northern" district of the city of Kursk
This article presents the results of engineering and geological surveys on the built-up territory of the Kursk city agglomeration. A hydroisogypsum map was built, the flow filtrationrate was calculated, and it’s direction was determined. Protective measures were also proposed to prevent flooding of the built-up are
Measurement of the decay form factors in the OKA experiment
A precise measurement of the vector and axial-vector form factors difference
in the decay is presented.
About 95K events of are selected in
the OKA experiment. The result is .
Both errors are smaller than in the previous measurements.Comment: 9 pages, 8 figure
Study of the system in the mass range up to 1200 MeV
The reaction has been studied with GAMS-2000
spectrometer in the secondary 38 GeV/c -beam of the IHEP U-70
accelerator. Partial wave analysis of the reaction has been performed in the
mass range up to 1200 MeV. The -meson is seen as a sharp
peak in S-wave. The -dependence of production cross section has
been studied. Dominant production of the at a small transfer
momentum confirms the hypothesis of Achasov and Shestakov about significant
contribution of the exchange () in the mechanism
of meson production in -channel of the reaction.Comment: 4 pages, 3 figures, talk given at HADRON'9
