Abstract: Because Romania is an EU-member country since 2007, obviously it must, in concordance with the adhesion agreement, align” to the financing systems of agriculture and rural development practised in the European Union. Under the context of the financial PAC reforms, available for our country, too, the financing of the Romanian agriculture is made with European Union funds, and also with funds from the state budget (public funds) directed in supporting programs for farmers. In the conditions mentioned above, PAC implementation in Timi County aim at the adoption of farmer-supporting mechanisms at territorial level and their impact on holding development.

Abstract: The financial agricultural support, with common and nationalpublic funds, and also with the help of the credits supplied by specialized banks (Agricultural Credit – France, Robobank – The Netherlands, Raiffeisen Bank – Austria and Germany), permitted the accomplishment of holding sustainable capitalization and also the financing of intermediary consumptions adequate to high-quality technologies, materialized in high efficiencies, which, in their turn, generated reduced unitary costs, competitiveness and profitableness.
Clinical importance of aspirin and clopidogrel resistance
Gergely Feher,Andrea Feher,Gabriella Pusch,Katalin Koltai
World Journal of Cardiology , 2010,
Abstract: Aspirin and clopidogrel are important components of medical therapy for patients with acute coronary syndromes, for those who received coronary artery stents and in the secondary prevention of ischaemic stroke. Despite their use, a significant number of patients experience recurrent adverse ischaemic events. Interindividual variability of platelet aggregation in response to these antiplatelet agents may be an explanation for some of these recurrent events, and small trials have linked “aspirin and/or clopidogrel resistance”, as measured by platelet function tests, to adverse events. We systematically reviewed all available evidence on the prevalence of aspirin/clopidogrel resistance, their possible risk factors and their association with clinical outcomes. We also identified articles showing possible treatments. After analyzing the data on different laboratory methods, we found that aspirin/clopidogrel resistance seems to be associated with poor clinical outcomes and there is currently no standardized or widely accepted definition of clopidogrel resistance. Therefore, we conclude that specific treatment recommendations are not established for patients who exhibit high platelet reactivity during aspirin/clopidogrel therapy or who have poor platelet inhibition by clopidogrel.

Abstract: During the last 15 years, Common Agricultural Policy gas changed dramatically successive to the pressure exerted by the European society and by its economy under development. The reforms from 2003-2004 marked out a new step within this process, introducing the separation of direct payments through the single payment system (SPS) in most sector belonging to the first CAP pillar and strengthening the rural development policy, the second PAC pillar. The process continued with reforms in the sectors of sugar, fruit and vegetables, and in the wine production sector. The new CAP objectives supported by Health-Check (CAP-HC) aim at the practicing of agriculture in concordance with the environment, which would lead to the improvement of food safety by increasing food quality, improving competitiveness between agricultural products on the internal EU markets, and also worldwide, and by providing social balance through the stabilization of agricultural incomes and the creation of new income sources.
Generalized Drinfeld-Sokolov Hierarchies and W-Algebras
L. Feher
Physics , 1992,
Abstract: We review the construction of Drinfeld-Sokolov type hierarchies and classical W-algebras in a Hamiltonian symmetry reduction framework. We describe the list of graded regular elements in the Heisenberg subalgebras of the nontwisted loop algebra based on $gl_n$ and deal with the associated hierarchies. We exhibit an $sl_2$ embedding for each reduction of a Kac-Moody Poisson bracket algebra to a W-algebra of gauge invariant differential polynomials.
KdV type systems and W-algebras in the Drinfeld-Sokolov approach
Laszlo Feher
Physics , 1995,
Abstract: The generalized Drinfeld-Sokolov construction of KdV systems is reviewed in the case of an arbitrary affine Lie algebra paying particular attention to Hamiltonian aspects and $\W$-algebras. Some extensions of known results as well as a new interpretation of the construction are also presented.
Wakimoto realizations of current and exchange algebras
L. Feher
Physics , 1998, DOI: 10.1023/A:1021684501505
Abstract: Working at the level of Poisson brackets, we describe the extension of the generalized Wakimoto realization of a simple Lie algebra valued current, J, to a corresponding realization of a group valued chiral primary field, b, that has diagonal monodromy and satisfies $Kb'=Jb$. The chiral WZNW field b is subject to a monodromy dependent exchange algebra, whose derivation is reviewed, too.
Dynamical r-matrices and Poisson-Lie symmetries in the chiral WZNW model
L. Feher
Physics , 2002,
Abstract: We briefly review the possible Poisson structures on the chiral WZNW phase space and discuss the associated Poisson-Lie groupoids. Many interesting dynamical r-matrices appear naturally in this framework. Particular attention is paid to the special cases in which these r-matrices satisfy the classical dynamical Yang-Baxter equation or its Poisson-Lie variant.
Poisson-Lie dynamical r-matrices from Dirac reduction
L. Feher
Physics , 2004, DOI: 10.1007/s10582-004-9788-9
Abstract: The Dirac reduction technique used previously to obtain solutions of the classical dynamical Yang-Baxter equation on the dual of a Lie algebra is extended to the Poisson-Lie case and is shown to yield naturally certain dynamical r-matrices on the duals of Poisson-Lie groups found by Etingof, Enriquez and Marshall in math.QA/0403283.
Dynamical r-matrices and the chiral WZNW phase space
L. Feher
Physics , 2001, DOI: 10.1134/1.1490103
Abstract: The dynamical generalization of the classical Yang-Baxter equation that governs the possible Poisson structures on the space of chiral WZNW fields with generic monodromy is reviewed. It is explained that for particular choices of the chiral WZNW Poisson brackets this equation reduces to the CDYB equation recently studied by Etingof--Varchenko and others. Interesting dynamical r-matrices are obtained for generic monodromy as well as by imposing Dirac constraints on the monodromy.
