Ultra-high energy cosmic ray investigations by means of EAS muon density measurements

A new approach to investigations of ultra-high energy cosmic rays based on the ground-level measurements of the spectra of local density of EAS muons at various zenith angles is considered. Basic features of the local muon density phenomenology are illustrated using a simple semi-analytical model. It is shown that muon density spectra are sensitive to the spectrum slope, primary composition, and to the features of hadronic interaction. New experimental data on muon bundles at zenith angles from 30 degrees to horizon obtained with the coordinate detector DECOR are compared with CORSIKA-based simulations. It is found that measurements of muon density spectra in inclined EAS give possibility to study characteristics of primary cosmic ray flux in a very wide energy range from 10^15 to 10^19 eV.Comment: 7 pages, 7 figures.

Право на жизнь: момент возникновения и утраты

The subject of the article is the right to life interpretation issue, as well as the definition of the term "life" applicable in the legal field, the study of the problems of establishing of the constitutional right to life realization moment and its loss. This is necessary due to the formalized nature of law and the unification of the legal categorical apparatus, controversy in the scientific community, as well as the lack of a holistic understanding of the moments of its origin and loss, which will improve modern legislation in the field of protecting the right to life, eliminate existing contradictions.The purpose of the study is to confirm or refute the author's hypothesis about the moment of the emergence of the right to life and its termination as processes interrelated with the context and society. The author interests how this moment is fixed in current Russian legislation as well as in international legal norms and the constitutions of some foreign countries.The methodology. The following general scientific and special methods of cognition were used in the work: dialectical, systemic, historical, comparison, analysis and synthesis, formal legal and statistical methods. The method of comparison was used in the analysis of the texts of constitutions in order to consolidate the moments of the emergence and loss of the right to human life. The formal legal method made it possible to identify contradictions in the legislation of Russia in terms of issues related to the emergence and loss of the right to life. The use of these methods in combination with the latest achievements made it possible to identify and analyze the content, essence and features of the emergence and loss of the human right to life in the Russian Federation and foreign states.The main results, scope of application. Within the framework of the scientific and practical problem the author considers various approaches to the right to life emergence and loss moments, identifies the main problems of the current legislation of Russia and compares it with international legal norms and the constitutions of some foreign countries in order to fix the right to life emergence and loss the moments.Conclusions. The moment of the occurrence of the right to life must be recognized as a birth of viable infant, and the moment of loss of the right to life – the onset of his death. The right to life of a premature newborn, including those with extremely low body weight, as well as those with certain complications, is realized by providing him with full medical care.Рассмотрены различные подходы к определению моментов возникновения и утраты права на жизнь, обозначены основные проблемы действующего законодательства России и проведено его соотношение с международно-правовыми нормами и конституциями некоторых зарубежных стран на предмет закрепления начала и окончания действия права на жизнь. Отмечено, что в научной среде и законодательстве отсутствует целостное понимание о моменте возникновения и утраты права на жизнь, что вызывает проблемы в правоприменительной деятельности по охране рассматриваемого права. Сделан вывод о том, что моментом возникновения права на жизнь необходимо признавать его рождение жизнеспособным младенцем, а моментом утраты – наступление его смерти

Calibration of the NEVOD-EAS array for detection of extensive air showers

In this paper we discuss the calibration of the NEVOD-EAS array which is a part of the Experimental Complex NEVOD, as well as the results of studying the response features of its scintillation detectors. We present the results of the detectors energy calibration, performed by comparing their response to different types of particles obtained experimentally and simulated with the Geant4 software package, as well as of the measurements of their timing resolution. We also discuss the results of studies of the light collection non-uniformity of the NEVOD-EAS detectors and of the accuracy of air-shower arrival direction reconstruction, which have been performed using other facilities of the Experimental Complex NEVOD: the muon hodoscope URAGAN and the coordinate-tracking detector DECOR.Comment: 16 pages, 17 figures, To be submitted to Nuclear Instruments and Methods

EAS array of the NEVOD Experimental Complex

A new setup for registration of the electromagnetic component of the EAS at the “knee” region of the energy spectrum of primary cosmic rays (PCR) is now under construction on the basis of the experimental complex NEVOD-DECOR (Moscow, Russia). The EAS array detecting system has a cluster organization. Clusters are located in the MEPhI campus. The specific features of the array registering system that provides particle detection, data acquisition, cluster synchronization and events selection are discussed. The results of counter characteristics study are also presented

Investigation of cascade showers in the Cherenkov water detector NEVOD

A technique for the reconstruction of cascade profiles by means of Cherenkov radiation in the water of the NEVOD detector is discussed. NEVOD is equipped with a dense spatial lattice of optical modules. The analyzed cascades have been generated either along near-horizontal muons (zenith angles between 85 and 90°), which's tracks are reconstructed by means of the tracking detector DECOR, or by muons with unknown tracks over a wider zenith angle range of 50-90°. Mean cascade profiles and energy spectra of cascades measured during the experimental series of about 7950 hours of 'live time' are presented
