Measurement of the η\eta -η′\eta' mixing angle in π−\pi^{-} and K−K^{-} beams with GAMS-4π4\pi Setup

The results of mixing angle measurement for $\eta'$, $\eta$ mesons generated in charge exchange reactions with $\pi^{-}$ and $K^{-}$ beams are preseneted. When the $\eta'$, $\eta$ mesons are described in nonstrange(NS)--strange(S) quark basis the $\pi^{-}$ and $K^{-}$ beams allow to study $|\eta_{q}>$ and $|\eta_{s}>$ parts of the meson wave function. The cross section ratio at $t'=0$ (GeV/c)$^{2}$ in the $\pi^{-}$ beam is $R_{\pi}(\eta'/\eta)= 0.56 \pm 0.04$, results in mixing angle $\phi_{P} = (36.8 \pm 1.)^{o}$. For $K^{-}$ beam the ratio is $R_{K}(\eta'/\eta)= 1.30 \pm 0.16$. It was found that gluonium content in $\eta'$ is $\sin^{2}\psi_{G}= 0.15 \pm 0.06$. The experiment was carried out with GAMS-4$\pi$ Setup.Comment: 6 pages, 4 figures, 1 table, to be submitted in European physical journal C. Minor changes, the Bibliography extende

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

Study of the ηπo\eta\pi^o system in the mass range up to 1200 MeV

The reaction $\pi^-p \to \eta\pi^o n$ has been studied with GAMS-2000 spectrometer in the secondary 38 GeV/c $\pi^-$-beam of the IHEP U-70 accelerator. Partial wave analysis of the reaction has been performed in the $\eta\pi^o$ mass range up to 1200 MeV. The $a_0(980)$-meson is seen as a sharp peak in S-wave. The $t$-dependence of $a_0(980)$ production cross section has been studied. Dominant production of the $a_0(980)$ at a small transfer momentum $t$ confirms the hypothesis of Achasov and Shestakov about significant contribution of the $\rho_2$ exchange ($I^GJ^{PC}=1^+2^{--}$) in the mechanism of $a_0(980)$ meson production in $t$-channel of the reaction.Comment: 4 pages, 3 figures, talk given at HADRON'9

Dislocation of the penis: a rare case of genital trauma

Traumatic dislocation of the penis is one of the rarest types of genital trauma. This type of injury is accompanied by a violation of the integrity of the skin and the penile ligamentous apparatus, with the dislocation of the penis into the scrotum under the skin of the thigh, or the area of the pubic joint. The low occurrence frequency of such injuries and the small number of observations described in the literature entails the absence of generally accepted treatment tactics for this category of patients. The article describes a clinical case of successfully treated traumatic dislocation of the penis with penile transposition into the pubic joint area and the formation of subcutaneous urinary leakage after late treatment of the patient for medical care

Measurement of the K+→μ+νμγK^+\rightarrow{\mu^+}{\nu_{\mu}}{\gamma} decay form factors in the OKA experiment

A precise measurement of the vector and axial-vector form factors difference $F_V-F_A$ in the $K^+\rightarrow{\mu^+}{\nu_{\mu}}{\gamma}$ decay is presented. About 95K events of $K^+\rightarrow{\mu^+}{\nu_{\mu}}{\gamma}$ are selected in the OKA experiment. The result is $F_V-F_A=0.134\pm0.021(stat)\pm0.027(syst)$. Both errors are smaller than in the previous $F_V-F_A$ measurements.Comment: 9 pages, 8 figure
