Determination of the cross section of the proton, pion and neutron inelastic interaction with lead and carbon nuclei at 0.5 - 5.0 TeV energies (PION experiment)

Experimental results on the cross section of the single pion, proton and neutron inelastic interaction with carbon and lead nuclei in the 0.5 to 5.0 TeV energy interval obtained on the PION installation (Mount Aragats, Armenia, 3250 m) are presented. For this purpose the (N pi)/(N p) and inelastic (p Fe)/(pi Fe) ratios measured directly on the installation as well as the calculated inelastic (p A)/(pi A) dependence on the target nucleus atomic numbers were used

Experimental Investigation of the Nature of the Knee in the Primary Cosmic Ray Energy Spectrum with the GAMMA experiment

We present preliminary results obtained by a novel difference method for the study of the nature of the knee in the energy spectrum of the primary cosmic radiation. We have applied this method to data from the GAMMA experiment in Armenia. The analysis provides evidence for the possible existence of a nearby source of primary cosmic rays in the Southern hemisphere.Comment: 17 pages, 5 figure

Marital status of a patient in the formation of his attitude to the organization of medical care provided on an outpatient basis

Introduction. The marital status of the patient is an important factor that affects his behavior, attitude to health and the healthcare system. Family relationships can have a positive or negative impact on the level of self-esteem, general psychological stability and readiness for treatment. For example, many people in stable relationships are more likely to monitor their health, visit doctors regularly and receive the necessary medical care. However, there are also negative aspects of marital status that can affect the patient's attitude to the healthcare system. For example, some patients may experience fear and embarrassment when seeking medical care without their spouse or partner. There are also cases when a patient's unwillingness to go to doctors is due to the fact that he does not want financial or emotional help from his family, but prefers to cope with his problems on his own. Thus, marital status is an important factor that must be taken into account when analyzing the attitude of patients to the healthcare system. Studying this problem can help medical institutions develop more effective service strategies and increase patient satisfaction.Materials and methods. For the analysis, 495 patients of medical organizations in Moscow were obtained by questioning. Two comparison groups were formed, the main group (the presence of marital relations) 292 people, the control group (the absence of marital relations) 203 people. Taking into account the nonparametric distribution of the primary data, the criterion of the reliability of differences χ2 was used to compare the groups, and the association coefficient was used to determine the dependence Ka.Results. According to the results of the analysis, taking into account the literature data, data on different approaches to the assessment of the medical care management system in patients with different family status were obtained.Conclusions. Family patients are more critical of the organization of the activities of individual departments of the polyclinic, but their criticism does not lead to a significant decrease in the overall assessment of the medical organization. Lonely patients make fewer specific claims, but reduce the overall assessment of the medical organization's activities

EAS muon distributions and primary mass composition from the GAMMA installation

Abstract The phenomenological characteristics of the muon component of extensive air showers with energies 10 6 −10 7 GeV are obtained with the GAMMA installation at Mt. Aragats in Armenia, (3200m a.s.l., 700 g.cm −2 ). The experimental results are compared with the simulation carried out using the CORSIKA code. A new selection parameter is analysed for an unbiased determination of the primary mass composition

All-particle primary energy spectrum in the 3-200 PeV energy range

We present all-particle primary cosmic-ray energy spectrum in the 3-200 PeV energy range obtained by a multi-parametric event-by-event evaluation of the primary energy. The results are obtained on the basis of an expanded EAS data set detected at mountain level (700 g/cm^2) by the GAMMA experiment. The energy evaluation method has been developed using the EAS simulation with the SIBYLL interaction model taking into account the response of GAMMA detectors and reconstruction uncertainties of EAS parameters. Nearly unbiased (<5%) energy estimations regardless of a primary nuclear mass with an accuracy of about 15-10% in the 3-200 PeV energy range respectively are attained. An irregularity ('bump') in the spectrum is observed at primary energies of ~74 PeV. This bump exceeds a smooth power-law fit to the data by about 4 standard deviations. Not rejecting stochastic nature of the bump completely, we examined the systematic uncertainties of our methods and conclude that they cannot be responsible for the observed feature.Comment: Accepted by J.Phys.G: Nucl.Part.Phy
