RF-POWER UPGRADE SYSTEMS WITH ENERGY COMPRESSION FOR ELECTRON LINACS

ms classification and researching the questions on perspectivity and expediency of their use as the RF-feed sources for electron linacs (and, in general case, not only for electron). The present report is devoted to classification of the RFenergy compression systems (ECS), that may be used as the RF-feed sources for electron linacs. The classification scheme of ECS is shown on fig. 1. As far as the working principle of each particular system is basically determined by an energy storage element used, from this point if view all systems can be divided into three groups: a) the systems with energy storage in cavities; b) the systems with energy storage in DL; c) the systems with energy storage in combined storing elements. The first group concern ECS, in which the RF-field energy is accumulated in a high-quality-factor cavity and the output pulse is formed at the expense of a wave, emitted from a cavity. In systems of the second group the RF-energy is accumulated in DL, and the outpu

Transmutation of Nuclear Materials Can Be Carried Out By Thermal Neutron Capture Reactions, By Spallation Type Reactions Or Via Photonuclear Reactions Caused By High-Energy

e reactor; production of nuclear fuel in breeders; the adoption of the nuclear reactors with a feedback loop around reactivity and so on. But the ideal fuel cycle can not be maintained in reactor-type nuclear plants only in consequence of the following circumstances: -It is impossible to transmutate Cs 137 and Sr 90 which define the residual activity of the nuclear waste in general; -The most perspective fuel cycles U 238 - Pu 239 and Th 232 - U 233 are characterized by the very low yield of delayed neutrons and it is impossible to supply nuclear safety of these cycles by standard methods; -Stabilization of reactivity is maintained by replacing of regulation rods and something can possibly seize. The problem of the "ideal" fuel cycle can be solved by using the external neutron source and by going to the conception of the subcritical blanket of the reactor. Under Keff

HEART RATE AND ITS ASSOCIATION WITH THE MAIN RISK FACTORS IN THE POPULATION OF MEN AND WOMEN OF WORKING AGE

Aim. To study the association of heart rate (HR) with the health parameters obtained in the ESSE-RF study.Material and methods. The data of the multicenter epidemiological study of ESSE-RF were used in the work. 8,343 men and 13,531 women aged 25-64 years were examined. The response to the survey was about 80%. The analysis is performed depending on the elevated heart rate. Education, place of residence, region, lipid profile, levels of C-reactive protein (CRP) and glucose, history of diabetes, anxiety and depression, elevated blood pressure were analyzed as factors possibly associated with increased heart rate. Epidemiological diagnosis of ischemic heart disease (IHD) was established using the Rose questionnaire, an electrocardiogram analysis, followed by the Minnesota code coding.Results. Almost every fifth inhabitant had a pulse rate of more than 80 beats/min. No significant difference was found between the sexes. The increase in heart rate in men, starting in the age group 25-34 years to 45-54, and in women only up to 35-44 years with subsequent reduction in men and women was found. The prevalence of increased heart rate varies from region to region. The highest heart rate in men is recorded in Orenburg (33.1%), Ossetia (Alania) and Volgograd (29.7% and 27.6%, respectively), in women – in Vladivostok (37.4%), and the lowest heart rate in both gender groups– in Samara (9.4% for men and 8.1% for women). Increase in heart rate in men with secondary education [odds ratio (OR) 1.24; 95% confidence interval (CI) 1.10-1.40], smokers and quitters (OR 1.90, 95% CI 1.63-2.27), who did not drink alcohol during the last year (OR 1.18, 95% CI 1.021.37), living in rural areas (OR 1.22, 95% CI 1.04-1.42), who are obese (OR 1.27, 95% CI, 1.101.45), having elevated blood pressure (OR 2.24, 95% CI 1.88-2.67), elevated levels of triglycerides, glucose and CRP was found after correction for age, region and all indicators included in the analysis (multidimensional model). The heart rate >80 beats/min was found significantly less often in people with history of myocardial infarction. A different model was found in women, it included, like in men, living in the village, elevated levels of blood pressure, triglycerides, glucose and CRP, but not education, smoking and alcohol consumption, obesity. Anxiety, low level of high-density lipoproteins and history of diabetes mellitus were also in the model in women.Сonclusion. Significant associations between increased heart rate and metabolic risk factors, inflammation and residence in the village are found
