Abstract: Tourism Planning Opportunities for The Salt Lakes of Ocnele Mari and Ocni a. Ocnele Mari used to be a popular balneal tourism destination in the Southern region of Romania, Oltenia. Due to the hilly climate and the two balneal establishments of Ocnele Mari and Ocni a, tourists could find the necessary natural cure factors for rheumatic and cardiovascular diseases. However, the salt from Ocnele Mari was also used for industrial purposes, being extracted through solution mining, which proved to be detrimental to the environment. Salt underground dissolution caused land subsidence and landslide in the area, together with the formation of large salt lakes. Security became an issue, the number of tourists diminished and the balneal equipment became obsolete because of lack of modernization investment. Under these circumstances, on the basis of field work, we have reached the conclusion that a better planning of the resort and of the salt lakes would contribute to the economic development of the region.
L’importance des projets paysagers d’aménagement dans le changement de la perception sur les paysages périphériques. Etude de cas : Parcul Tineretului (Le Parc de la Jeunesse) de Craiova
Cinq Continents , 2011,
Abstract: Towns and cities change over time, and this process of change is inevitable because the political, economic and social systems of a community constantly generate new demands, that trigger urban development. This urban progress has to take into consideration not only the socio-economic development of the areas considered,but also the quality of life and most importantly, the aesthetics of residential areas, green areas, leisure and recreation areas, that exist in any city. Having as starting point the actual case of the Youth Park from Craiova, our attempt is to analyse the evolution and the transformations underwent by this park, during the decades aswell as the surrounding area. Therefore, we shell discuss the importance of landscape planning projects which subordinate to public actors’ decisions and meet the European requirements of urban regeneration.

Abstract: The main objective of this paper is to assess the water quality of some rivers from Brasov, Braila and Galati counties (Timis, Danube and Prut) using atomic and optical methods: Atomic Absorption Spectrometry (AAS), UV-VIS Spectrometry and Turbidimetry. The concentrations of Cd, Co, Cr, Cu, Fe, Ni, Pb and Zn in the water samples were determined by AAS technique using the AVANTA GBC spectrometer from Valahia University of Targoviste, with flame and hollow cathode lamps (HCL). The UV-VIS spectrometric and turbidimetric determinations were carried out at Physics Department, “Dunarea de Jos” University of Galati, using WTW - TURB 430 IRIR/T portable turbidimeter and Perkin Elmer Lambda 35 UV-VIS Spectrometer. The river water turbidity and absorbencies are correlated with the concentrations of heavy elements detected in the analyzed water samples. This study is part of a partnership project funded by National Plan of Research, Developing and Innovation, of implementation of high precision and sensibility methods for the biomonitoring of the environmental pollution in South, South-East and Central regions of Romania (Project 72-172/2008).

Advances in Sexual Medicine (ASM) , 2012, DOI: 10.4236/asm.2012.22005
Abstract: The clinical signs of hyperandrogenemia, commonly seen in polycystic ovarian syndrome (PCOS) patients combined with obesity and infertility can cause emotional distress. There are however few data about the psychosocial and sexual function of patients with PCOS. Objectives: The aim of the study was to investigate the sexual function in patients with obesity and/or PCOS using Female sexual function inventory (FSFI) before and after metformin treatment. Design and Methods: In the present study were included 79 patients divided into three groups—group 1 Obese (n = 22); group 2 Lean PCOS (n = 41) and group 3 Obese PCOS (n = 16). All of the subjects completed FSFI questionnaire. In patients who had insulin resistance (OGTT + IRI) metformin treatment was started in dose 1700 - 3000 mg/day. Results: Obese women without PCOS showed significantly higher scores on total FSFI and all domains except from desire compared to lean PCOS subjects. Although the differences do not reach statistical significance, lean PCOS patients have the lowest scores on all domains. FSFI score correlates negatively only with androstendione levels. Women with and without hyperandrogenemia do not show differences in FSFI score. It is interesting to note that LH but not FSH shows moderate positive correlation to all domains of FSFI. FSFI scores do not show correlation to the indices of carbohydrate metabolism (blood glucose and IRI during OGTT), lipid profile, and arterial pressure. After metformin treatment there was an increase in all FSFI domain scores although statistical significance was noted only for the total FSFI score and the domains lubrication and pain, probably because of the small number of patients. Conclusions: Lean PCOS patients have lower scores on FSFI than obese patients with or without PCOS. The hyperandrogenemia is not a determinant for sexual dysfunction in PCOS women. Metformin treatment has a favorable effect on sexual function.
Review of Finance and Banking , 2009,
Abstract: The safety net provided by deposit insurance systems gain heavily in weight attimes of crisis. The correct set of such a cushion is critical to its effectiveness. While ithelps to prevent bank runs, the severe market distortions are of great concern. The shortterm benefit of public confidence can be, far and away, offset by its long run negative effectsconsisting mainly in increased moral hazard, heavy public costs and impaired competition.
South-East Region in Bulgaria: Economic Performance and Key Sectors Analysis
Annals of Dun?rea de Jos University. Fascicle I : Economics and Applied Informatics , 2008,
Abstract: The present paper attempts to provide insight into the economicperformance of the South-east region (SER) of Bulgaria by presenting quantitativerelationships between sectors in the regional economy. Methodologically it is basedon the construction of the regional Input–Output model. It was carried out troughapplying the non-servey GRIT technique, based on Flegg & Webber locationquotient (2000). The dirived Rasmussen & Hirschman backward linkages andMattas & Shrestha input-output elasticities from the model enable to identify thekey economic sectors within the region. This could be considered as a starting pointfor the future impact assesment of different EU policies, as well as designing ofbetter regional development strategies, assuring better economic performance.
Compliance in the EU enlargement process: The limits of conditionality
Antoaneta Dimitrova
European Integration Online Papers , 2007,
Abstract: In this article we analyze the effectiveness of EU conditionality. Viewing accession negotiations as a bargaining game, we find incentives to defect exist if the final date of accession is known, but conditions for cooperation prevail if the date is not known. Therefore we find that regardless of domestic conditions, EU conditionality is not equally effective throughout the period of preparation of a candidate for accession. Its effectiveness decreases sharply when the accession date is set and at that stage, as empirical evidence shows, the EU accepts the candidate’s state of reforms as sufficient. This can lead to potential problems with the transposition of EU directives just before and after accession. Our empirical overview shows that by means of breaking the process of enlargement into multiple stages and attaching conditions to the attaining every stage, the EU has aimed to prevent candidates from abandoning reform efforts by increasing their uncertainty about the final date of accession.
Systemic Risk Identification, Modelling, Analysis, and Monitoring: An Integrated Approach
Antoaneta Sergueiva
Computer Science , 2013,
Abstract: Research capacity is critical in understanding systemic risk and informing new regulation. Banking regulation has not kept pace with all the complexities of financial innovation. The academic literature on systemic risk is rapidly expanding. The majority of papers analyse a single source or a consolidated source of risk and its effect. A fraction of publications quantify systemic risk measures or formulate penalties for systemically important financial institutions that are of practical regulatory relevance. The challenges facing systemic risk evaluation and regulation still persist, as the definition of systemic risk is somewhat unsettled and that affects attempts to provide solutions. Our understanding of systemic risk is evolving and the awareness of data relevance is rising gradually; this challenge is reflected in the focus of major international research initiatives. There is a consensus that the direct and indirect costs of a systemic crisis are enormous as opposed to preventing it, and that without regulation the externalities will not be prevented; but there is no consensus yet on the extent and detail of regulation, and research expectations are to facilitate the regulatory process. This report outlines an integrated approach for systemic risk evaluation based on multiple types of interbank exposures through innovative modelling approaches as tensorial multilayer networks, suggests how to relate underlying economic data and how to extend the network to cover financial market information. We reason about data requirements and time scale effects, and outline a multi-model hypernetwork of systemic risk knowledge as a scenario analysis and policy support tool. The argument is that logical steps forward would incorporate the range of risk sources and their interrelated effects as contributions towards an overall systemic risk indicator, would perform an integral analysis of ...

Intelligent Information Management (IIM) , 2010, DOI: 10.4236/iim.2010.22016
Abstract: We analyze the existence and uniqueness of the optimal control for a class of exactly controllable linear systems. We are interested in the minimization of time, energy and final manifold in transfer problems. The state variables space X and, respectively, the control variables space U, are considered to be Hilbert spaces. The linear operator T(t) which defines the solution of the linear control system is a strong semigroup. Our analysis is based on some results from the theory of linear operators and functional analysis. The results obtained in this paper are based on the properties of linear operators and on some theorems from functional analysis.

Abstract: Polycystic ovarian syndrome (PCOS) is one of the most common endocrine disturbances in women of reproductive age. Besides its well-known effects on reproductive health, it is also linked to increased cardiovascular risk in later life. The aim of this study is to investigate some classical cardiovascular risk factors in a crossectional study of Bulgarian women with PCOS and/or obesity. We performed a retrospective medical chart review of 375 women from an university endocrine clinic. We found significant differences in the indices of carbohydrate metabolism, blood pressure, lipid profile, rate of liver steatosis, and the levels liver enzymes and hematological results between the lean and obese PCOS women. Obese women without PCOS did not show significantly different results in their OGGT form obese PCOS women. Waist-to-stature-ratio (WSR) correlated better with the baseline IRI levels and lipid profile than waist-to-hip-ratio (WHR) that makes it a better marker for unfavorable metabolic profile. 1. Introduction PCOS is a prevalent disorder that affects approximately 6–10% of women of reproductive age [1, 2] and is a major cause of menstrual disturbances, hirsutism, and female anovulatory infertility. Many PCOS women show evidence of insulin resistance and hyperandrogenism. Current evidence suggests that insulin resistance and compensatory hyperinsulinemia are a central feature of PCOS [3]. Hyperinsulinemia appears to play an important pathogenic role in the hyperandrogenism of both obese and lean women with PCOS [4–6]. According to some studies, PCOS patients have an increased risk for diabetes mellitus [7, 8] and often show an adverse cardiovascular risk profile-increased rate of arterial hypertension [9, 10], dislipidemia [10–14], and subclinical inflammation and atherosclerosis [15–17]. Cardiovascular risk factors are usually present even in younger age and this suggests that the chronic disturbances in hormonal and metabolic status typical for the syndrome predispose the patients to development of early atherosclerosis and premature clinical presentation of cardiovascular disease. Obesity plays an important role in the pathogenesis of PCOS, and around 30–75% of PCOS women are obese [18–20]. Over the last 20 years, the prevalence of obesity has dramatically increased, with probable associated increase in PCOS. Obesity contributes to the prevalence of the metabolic syndrome in PCOS patients [21]. Central obesity is often associated with PCOS [22] and carries increased risk for developing cardiovascular disease and type 2 diabetes [23]. The specific
