Abstract: The presented paper deals with a compex evaluation of the problem of extraction of eruptive rocks which are mostly used in the building practice in Slovakia. The greatest attention is devoted to the water absorp-tion analysis, which represents the standard criterion conditioning the eruptive rocks extraction. Partial results of a study dealing with eruptive rocks water absorption are introduced in the paper as well. The results achieved in numerous experiments proved the fact that the negative effect of water contained in eruptive rocks on their pro-perties depends on the pore structure (positive or negative) rather than on the extent (percentage) of adsorption.. The results of the experiments were applied in the process of compiling the basic SCM 72 1800 Standards (Na-tural Stone for Construction and Stone Products) where water absorption is mentioned as an informative value.
Efficiency analysis of producers’ organizations (Case of South Eastern and Central planning regions of Bulgaria)
Darina Zaimova
Perspectives of Innovations, Economics and Business , 2010,
Abstract: The main aim of this paper is to compare two alternative methods for estimating frontier functions and measuring efficiency in production. The application of Data Envelopment Analysis (DEA) and Stochastic Frontier Analysis (SFA) to the same data panel provides insights in estimating technical efficiency of producers’ organizations in selected regions in Bulgaria.
T-Norm-Based Orderings on Y[0,1]n

Advances in Electrical and Electronic Engineering , 2006,
Abstract: In this paper we recall orderings based on t-norms, which could help to select the best suited decision procedure in many practical situations. We discuss several refinements of t-norm based orderings which break some of possible ties.

Abstract: The importance of art therapy in everyday practice with handicap children, especially during the time dedicated to practical art, represents the basic of this report. By that most important are hand made activity, drawing, and music, and their positive influence on children emotional life.

Abstract: The study population consisted of 5118 employees and their relatives, aged 20 to 70 years, who were enrolled in the baseline evaluation of a cohort study. MS was assessed according to the criteria of the National Cholesterol Education Program, ATP III and physical activity with a validated self-administered questionnaire. Associations between physical activity and MS risk were assessed with multivariate logistic regression models.The prevalence of the components of MS in the study population were: high glucose levels 14.2%, high triglycerides 40.9%, high blood pressure 20.4%, greater than healthful waist circumference 43.2% and low-high density lipoprotein 76.9%. The prevalence of MS was 24.4%; 25.3% in men and 21.8% in women. MS risk was reduced among men (OR 0.72; 95%CI 0.57–0.95) and women (OR 0.78; 95%CI 0.64–0.94) who reported an amount of ≥30 minutes/day of leisure-time activity, and among women who reported an amount of ≥3 hours/day of workplace activity (OR 0.75; 95%CI 0.59–0.96).Our results indicate that both leisure-time and workplace activity at different intensity levels, including low-intensity significantly reduce the risk of MS. This finding highlights the need for more recommendations regarding the specific amount and intensity of leisure-time and workplace activity needed to prevent MS.Metabolic Syndrome (MS) is a common disorder caused by a combination of unhealthy diet, sedentary lifestyle and genetic predisposition [1]. This syndrome is a major risk factor for several chronic diseases, mainly type 2 diabetes and cardiovascular diseases [2-5]. Some components of MS are highly prevalent in the Mexican population. These include high rates of central obesity [6], low levels of high density lipoprotein cholesterol (HDL), hypertriglyceridemia, hypoalphalipoproteinemia [7] and type 2 diabetes [8]. In fact, cardiovascular disease is the leading cause of death for both sexes, and type 2 diabetes is the second cause of death among women, and the third amon
A workplace physical activity program at a public university in Mexico can reduce medical costs associated with type 2 diabetes and hypertension

Abstract: objective: to assess the impact of a workplace leisure physical activity program on healthcare expenditures for type 2 diabetes and hypertension treatment. material and methods: we assessed a workplace program's potential to reduce costs by multiplying the annual healthcare costs of patients with type 2 diabetes and hypertension by the population attributable risk fraction of non-recommended physical activity levels. feasibility of a physical activity program was assessed among 425 employees of a public university in mexico. results: if 400 sedentary employees engaged in a physical activity program to decrease their risk of diabetes and hypertension, the potential annual healthcare cost reduction would be 138 880 us dollars. each dollar invested in physical activity could reduce treatment costs of both diseases by 5.3 dollars. conclusions: this research meets the call to use health economics methods to re-appraise health priorities, and devise strategies for optimal allocation of financial resources in the health sector.
Holographic Superconductors and Higher Curvature Corrections
Massimo Siani
Physics , 2010, DOI: 10.1007/JHEP12(2010)035
Abstract: We study a fully backreacted holographic model of a four-dimensional superconductor by including a higher curvature interaction in the bulk action. We study how the critical temperature and the field theory condensate vary in this model and conclude that positive higher curvature couplings make the condensation harder. We also compute the conductivity, finding significant deviations from the conjectured universal frequency gap to critical temperature ratio.
On inhomogeneous holographic superconductors

Physics , 2011,
Abstract: We study a model describing a four-dimensional holographic superconductor whose properties depend non-trivially on a particular spatial direction, namely a Josephson junction. We analyze the parameter dependence of the condensate and compare it to the condensed matter expectations.
The Eastern Enlargement of the European Union: Challenges to Democracy?1
Darina Malová, Branislav Dolny
Human Affairs , 2008, DOI: 10.2478/v10023-008-0006-4
Abstract: Recent scholarship assesses the impact of the European Union's conditionality on democracy in Central and Eastern Europe in a contradictory way. On one hand, the EU is perceived as a key agent of successful democratic consolidation and on other hand, the return of nationalist and populist politics in new member states has been explored in the context of the negative consequences of the hasty accession that undermined government accountability and constrained public debate over policy alternatives. This article explains this puzzle of the ambiguous effects of the EU's politics of conditionality, which promoted institutions stabilizing the horizontal division of powers, rule of law, human and minority rights protection, but which neglected norms and rules of participatory and/or popular democracy.
