PSYCHOSOMATICS IN EATING DISORDERS

Background: To study the psychosomatic options and dynamics in patients with eating disorders. To conduct a comparative study of psychosomatic characteristics of surveyed patients with eating disorders, taking into account the duration and severity of protein-energy deficiency and levels of catecholamines excretion; to reveal features of mental working capacity, basic mental processes and EEG data at different stages of eating disorders; to develop scientifically based effective methods and means for correcting pathological changes that have arisen as a result of prolonged protein-energy deficiency in eating disorders. Methods: Catamnestic, statistical, clinico-psychopathological with somatic, psychological and laboratory examination, anthropometry, high-performance liquid chromatography, electroencephalography. Statistical analysis of collected data was processed using the program IBM SPSS Statistics 22, the confidence level p-.001. Results: The long-term consequences of prolonged fasting in 500 women with eating disorders (ED), who applied for help at the RUDN department and were examined in 1987-2013, were studied. The most common somatic complications of prolonged proteinenergy deficiency were investigated. In addition to the clinical method and anthropometry, to measure the efficiency of weight gain after prolonged alimentary deficiencies and to treat anorexia nervosa patients the pathopsychological method of "Shabalina\u27s complex decoding" and analysis of catecholamine excretion rates in urine of patients with anorexia at different stages of therapy were used. Improvement of mental performance and general condition of the examined after applying the developed treatment was observed. Scientifically based principles of therapy, allowing to avoid complications of long-term fasting and during weight gain were suggested

K0S and Λ production in Pb-Pb collisions at sNN−−−−√=2.76 TeV

The ALICE measurement of K0S and Λ production at midrapidity in Pb-Pb collisions at sNN−−−√=2.76  TeV is presented. The transverse momentum (pT) spectra are shown for several collision centrality intervals and in the pT range from 0.4  GeV/c (0.6  GeV/c for Λ) to 12  GeV/c. The pT dependence of the Λ/K0S ratios exhibits maxima in the vicinity of 3  GeV/c, and the positions of the maxima shift towards higher pT with increasing collision centrality. The magnitude of these maxima increases by almost a factor of three between most peripheral and most central Pb-Pb collisions. This baryon excess at intermediate pT is not observed in pp interactions at s√=0.9  TeV and at s√=7  TeV. Qualitatively, the baryon enhancement in heavy-ion collisions is expected from radial flow. However, the measured pT spectra above 2  GeV/c progressively decouple from hydrodynamical-model calculations. For higher values of pT, models that incorporate the influence of the medium on the fragmentation and hadronization processes describe qualitatively the pT dependence of the Λ/K0S ratio

Measurement of charged jet suppression in Pb-Pb collisions at sNN \sqrt{{{s_{\mathrm{NN}}}}} = 2.76 TeV

A measurement of the transverse momentum spectra of jets in Pb-Pb collisions at √sNN = 2.76TeV is reported. Jets are reconstructed from charged particles using the anti-k T jet algorithm with jet resolution parameters R of 0.2 and 0.3 in pseudo-rapidity |η| < 0.5. The transverse momentum p T of charged particles is measured down to 0.15 GeV/c which gives access to the low p T fragments of the jet. Jets found in heavy-ion collisions are corrected event-by-event for average background density and on an inclusive basis (via unfolding) for residual background fluctuations and detector effects. A strong suppression of jet production in central events with respect to peripheral events is observed. The suppression is found to be similar to the suppression of charged hadrons, which suggests that substantial energy is radiated at angles larger than the jet resolution parameter R = 0.3 considered in the analysis. The fragmentation bias introduced by selecting jets with a high p T leading particle, which rejects jets with a soft fragmentation pattern, has a similar effect on the jet yield for central and peripheral events. The ratio of jet spectra with R = 0.2 and R = 0.3 is found to be similar in Pb-Pb and simulated PYTHIA pp events, indicating no strong broadening of the radial jet structure in the reconstructed jets with R < 0.3

Influence of psychological distance between family members on teenager's motivation for studying

The objectives of the study are to identify the type of the relationship between students and their parents and its influence on academic performance; based on the result analysis, formulate a problem (problems) and suggest possible solutions. The results showed that students who have stronger ties with their parents are generally more motivated to study and demonstrate better academic performance than those who distance themselves from their families. The lack of attachment between parents and children can be a serious problem in adolescence life when mental health is being restructured.Los objetivos del estudio son identificar el tipo de relación entre los estudiantes y sus padres y su influencia en el rendimiento académico; basado en el análisis de resultados, formule un problema (problemas) y sugiera posibles soluciones. Los resultados mostraron que los estudiantes que tienen vínculos más fuertes con sus padres generalmente están más motivados para estudiar y demostrar un mejor rendimiento académico que aquellos que se distancian de sus familias. La falta de apego entre padres e hijos puede ser un problema grave en la vida de la adolescencia cuando se reestructura la salud mental

ALICE A Large Ion Collider Experiment

POLAR-2 is a follow-up GRB mission of POLAR, which has observed low levels of polarization degree and a temporal evolution of the polarization angle, indicating that time resolved studies of $\gamma$ photons polarization are required to constrain theoretical emission models of GRB’s. POLAR-2 detector aim to put in space a detector with one order of magnitude sensitivity improvement versus POLAR. POLAR-2 will be the most sensitive GRB detector covering half of the sky. The instrument, proposed by an international collaboration, was selected to be launched in 2024 to the China Space Station and operate for at least 2 years. POLAR-2 will use same plastic bar concept then POLAR but will be readout by SiPMT. The payload will also feature a spectrometer. The instrument is foreseen to perform detailed polarization measurements of at least 100 GRBs

D Meson Elliptic Flow in Noncentral Pb-Pb Collisions at root(S)(NN)=2.76 TeV

Azimuthally anisotropic distributions of D0, D+, and D*+ mesons were studied in the central rapidity region (|y|&lt;0.8) in Pb-Pb collisions at a center-of-mass energy sNN‾‾‾‾√=2.76  TeV per nucleon-nucleon collision, with the ALICE detector at the LHC. The second Fourier coefficient v2 (commonly denoted elliptic flow) was measured in the centrality class 30%–50% as a function of the D meson transverse momentum pT, in the range 2–16  GeV/c. The measured v2 of D mesons is comparable in magnitude to that of light-flavor hadrons. It is positive in the range 2&lt;6  GeV/c with 5.7σ significance, based on the combination of statistical and systematic uncertainties

The directed flow of charged particles at midrapidity is measured in Pb-Pb collisions at $\sqrt{s_{NN}}$=2.76 TeV relative to the collision plane defined by the spectator nucleons. Both, the rapidity odd ($v_1^{odd}$) and even ($v_1^{even}$) directed flow components are reported. The $v_1^{odd}$ component has a negative slope as a function of pseudorapidity similar to that observed at the highest RHIC energy, but with about a three times smaller magnitude. The $v_1^{even}$ component is found to be non-zero and independent of pseudorapidity. Both components show little dependence on the collision centrality and change sign at transverse momenta around 1.2-1.7 GeV/c for midcentral collisions. The shape of $v_1^{even}$ as a function of transverse momentum and a vanishing transverse momentum shift along the spectator deflection for $v_1^{even}$ are consistent with dipole-like initial density fluctuations in the overlap zone of the nuclei
