Management of Measurable Variable Cardiovascular Disease' Risk Factors.

Abstract: AIM: To summarize the main findings on variable cardiovascular risk factors and their management in everyday practice. ----- METHODS: A narrative review of the relevant literature known to the authors and incorporation of healthy changes tips in defined variable cardiovascular risk factors. ----- RESULTS: There are known variable cardiovascular risk factors to be claimed as those that should be changed in order to achieve a better prevention of cardiovascular disease development. But, most papers are informative and they didn't incorporate exact measures for each variable risk factor. Our paper shows exact measures for each variable cardiovascular risk factor that should be incorporate in everyday practice of family practitioners and cardiologists as well. ----- CONCLUSION: The best cardiovascular disease' prevention should include a multidisciplinary team of experts and the entire community with the support of governmental and non-governmental organizations that will contribute to improving the lifestyle of individuals and the entire community through their activities and legal provisions. The most important factors in cardiovascular disease management are: recognizing individual risk factors, monitoring them, and assisting in changes in life-style habits that directly affect the defined risk factors of a patient. The simplest and most practicable guidelines for CV prevention in accordance with the national, cultural and socioeconomic aspects of their country of work are needed.

How to achieve a 100% RES electricity supply for Portugal?

Abstract: Portugal is a country with an energy system highly dependent on oil and gas imports. Imports of oil and gas accounted for 85% of the country's requirements in 2005 and 86% in 2006. Meanwhile, the share of renewable energy sources (RES) in the total primary energy consumption was only 14% in 2006. When focusing only on electricity production, the situation is somewhat better. The share of RES in gross electricity production varies between 20% and 35% and is dependent on the hydropower production in wet and dry years. This paper presents, on a national scale, Portugal's energy system planning and technical solutions for achieving 100% RES electricity production. Planning was based on hourly energy balance and use of H 2 RES software. The H 2 RES model provides the ability to integrate various types of storages into energy systems in order to increase penetration of the intermittent renewable energy sources or to achieve a 100% renewable island, region or country. The paper also represents a stepping-stone for studies offering wider possibilities in matching and satisfying electricity supply in Portugal with potential renewable energy sources. Special attention has been given to intermittent sources such as wind, solar and ocean waves that can be coupled to appropriate energy storage systems charged with surplus amounts of produced electricity. The storage systems also decrease installed power requirements for generating units. Consequently, these storages will assist in avoiding unnecessary rejection of renewable potential and reaching a sufficient security of energy supply.

Dirac cohomology, unitary representations and a proof of a conjecture of Vogan

Abstract: U radu je dokazana slutnja D. Vogana, koja odredjuje infinitesimalni karakter ireducibilnog (g, K)-modula koji ima Diracovu kohomologiju razlicitu od nula. Infinitesimalni karakter je dan kao rho-translat najvece tezine K-tipa u Diracovoj kohomologiji. Diracova kohomologija se definira kao ker D / (im D \cap ker D), gdje D oznacava Diracov operator na zadanom (g, K)-modulu tenzoriranom sa spin modulom.
