Critical temperature for the nuclear liquid-gas phase transition (from multifragmentation and fission)

Critical temperature Tc for the nuclear liquid-gas phase transition is stimated both from the multifragmentation and fission data. In the first case,the critical temperature is obtained by analysis of the IMF yields in p(8.1 GeV)+Au collisions within the statistical model of multifragmentation (SMM). In the second case, the experimental fission probability for excited 188Os is compared with the calculated one with Tc as a free parameter. It is concluded for both cases that the critical temperature is higher than 16 MeV.Comment: 15 pages, 8 figure

Recoil Studies in the Reaction of 12-C Ions with the Enriched Isotope 118-Sn

The recoil properties of the product nuclei from the interaction of 2.2 GeV/nucleon 12-C ions from Nuclotron of the Laboratory of High Energies (LHE), Joint Institute for Nuclear Research (JINR) at Dubna with a 118-Sn target have been studied using catcher foils. The experimental data were analyzed using the mathematical formalism of the standard two-step vector model. The results for 12-C ions are compared with those for deuterons and protons. Three different Los Alamos versions of the Quark-Gluon String Model (LAQGSM) were used for comparison with our experimental data.Comment: 10 pages, 6 figures, submitted to Nucl. Phys.

Concerning Criteria for Assigning Infections to the Group of Diseases That Require Implementation of Measures for the Provision of Sanitary Protection of the Territories

Considered are the changes introduced into the list of infections, which require implementation of measures for the provision of sanitary protection of the territories, formalized in the international and state regulatory documents. Analyzed are the basic criteria for assigning infections to the category of – “requiring sanitary control”. Distinguished are the two groups of criteria for assigning infectious diseases to the group of infections that require implementation of measures for the provision of sanitary protection of the territories, either on the country-wide level or within the frames of interstate alliances

Deployment of Systematic Approach to the Assessment of Surveillance and Control over Ebola Virus Disease

Studied has been systematic approach as regards epidemiological surveillance and control over emergency situations in the sphere of sanitary-epidemiological welfare by the example of Ebola fever epidemic in West Africa countries. Based on the literature data available, analyzed have been measures for EVD surveillance and control, with reference to every stage of epidemiological process (source/ origin, agent, mechanism of transmission, recipient) at various levels of matter organization (global, regional, population, cellular, molecular, and sub-molecular). Following this, put forward have been primary areas for EVD control optimization

Measurement of the complete nuclide production and kinetic energies of the system 136Xe + hydrogen at 1 GeV per nucleon

We present an extensive overview of production cross sections and kinetic energies for the complete set of nuclides formed in the spallation of 136Xe by protons at the incident energy of 1 GeV per nucleon. The measurement was performed in inverse kinematics at the FRagment Separator (GSI, Darmstadt). Slightly below the Businaro-Gallone point, 136Xe is the stable nuclide with the largest neutron excess. The kinematic data and cross sections collected in this work for the full nuclide production are a general benchmark for modelling the spallation process in a neutron-rich nuclear system, where fission is characterised by predominantly mass-asymmetric splits.Comment: 18 pages, 14 figure

Organizational and Methodological Aspects of International Cooperation for the Provision of Sanitary-and-Epidemiological Welfare of the Population

The study in question of the structure and content of international cooperation in the sphere of sanitary-and-epidemiological welfare of the population in its various formats – on the UN, WHO, “G-8”, CIS, EurAsEC, SCO, and BRICS levels, as well as within the frames of bilateral relations between the Russian Federation and Republic of Kazakhstan – has made it possible to develop a model of international intercourse organization characterized by such functional features as assessment of the epidemiological situation peculiarities and IHR implementation status, realization of global strategy for infectious diseases control, systemic modernization of methodology, technologies, materials-and-equipment resources as well as human assets and production of medical immune-biological preparations (MIBP), stationary network and mobile complexes for emergency response in order to level the interstate potentials for the provision of effective prevention, detection and monitoring over emergency situations in the sphere of sanitary-and-epidemiological welfare of the population (ES). Top-priority in the list of the ESs is given to novel emerging infectious diseases control as it primarily demands improvement of the informational–and–analytical prognosis–modeling base within the frames of epidemiological surveillance system and sanitary protection of the state territories. Great need in such type of projects is substantiated based on the examples of Crimean-Congo hemorrhagic and West-Nile fevers control. Nevertheless, for the realization of the model, coordinating functional authority/agency is required

Complications of Sanitary-Epidemiological Situation and Risk of Emergency Situations Appearance in the Sphere of Sanitary and Epidemiological Well-Being in the Natural and Anthropogenic Catastrophes

Presented is the survey of emergency in the sphere of sanitary and epidemiological well-being of the population as per reported cases and data of the monitoring which has been carried out in 2010. Natural and anthropogenic disasters where such emergency is appeared or can appear are considered too. Natural catastrophes - earthquakes, volcanic explosions, overflow water, tsunami, dry spell and anthropogenic catastrophes - humanitarian, technogenic catastrophes, bioterroristic acts, accidents, related to operation with pathogen biological agents are examined in this review as the conditions preceding the emergency. Nosological entities for the infection diseases, which are most common in natural and anthropogenic catastrophes as well as conditions and factors predisposing to their activation, are identified. Shown is the data of adverse epidemiological situation caused by natural and anthropogenic catastrophes and the examples of use of the biological agents for terroristic aims

Sanitary Protection of the Territories within the Frames of Sanitary-Epidemiological Welfare Provision

Demonstrated is the structural and functional interrelation between sanitary protection of the territories, epidemiological monitoring, and the state sanitary-epidemiological surveillance. Sanitary protection of the territories (SPT) of the Russian Federation is a separate focus area authorizing sanitary prophylactic (anti-epidemic) activities, with a self-sustained sub-goal. It combines individual roles appertained to epidemiological monitoring and to federal sanitary-epidemiological surveillance, only in reference to a particular item - emergency situation in the sphere of sanitary-epidemiological welfare of the population. Specificity of the SPT is a balance between functionality and capacity of the monitoring, surveillance and control. Legislative and regulatory legal acts, which concern sanitary protection of the territory, provide the means for defining its basic organizational principles: country-wide activities, self-sufficiency and self-support of the Rospotrebnadzor, three-level hierarchical system, and information exchange

Critical Temperature for the Nuclear Liquid-Gas Phase Transition

The charge distribution of the intermediate mass fragments produced in p (8.1 GeV) + Au collisions is analyzed in the framework of the statistical multifragmentation model with the critical temperature for the nuclear liquid-gas phase transition $T_c$ as a free parameter. It is found that $T_c=20\pm3$ MeV (90% CL).Comment: 4 pages, 3 figures, published in Phys. Rev.
