  Possibilities to Evaluate the Sustainability of the Banks in Bulgaria using a Rating System ALER(TS)

  As the global financial crisis of 2007 shows, the modern banks are crucial for the stability of the financial sector and the economy as a whole. The study aims to present to academics and banking professionals the developed methodology of the evaluation system for sustainable development of the banking sector ALER(TS) and assess the extent of its ... As the global financial crisis of 2007 shows, the modern banks are crucial for the stability of the financial sector and the economy as a whole. The study aims to present to academics and banking professionals the developed methodology of the evaluation system for sustainable development of the banking sector ALER(TS) and assess the extent of its applicability based on real data analysis. The study argues that an independent and open-rating system to evaluating the banking sector contributes to increase its stability and competitiveness.

  Commutational Properties of Powers of Operators of Mixed Type Increasing the Powers

  The operators were considered in [11] with non-negative integers. Here they are considered with parameters in the space of the polynomials with complex coefficients or in the space of functions analytic in neighbourhoods of the origin. Power series description of the commutant of powers of is given and then the question about the ... The operators were considered in [11] with non-negative integers. Here they are considered with parameters in the space of the polynomials with complex coefficients or in the space of functions analytic in neighbourhoods of the origin. Power series description of the commutant of powers of is given and then the question about the minimal commutativity of H (in the sense of Raichinov [13]) is discussed.

  Posibilities for Ecologically-Oriented Utilization of Agricultural Biomass

  Biomass contributes the major share to the renewable energy sources (RES) potential in Bulgaria. A considerable amount of biomass is produces as a result of breeding animals, growing various crops, storing waste, maintaining green areas in the public sector or recycling waste waters. An important mechanism for effective utilization of energy ... Biomass contributes the major share to the renewable energy sources (RES) potential in Bulgaria. A considerable amount of biomass is produces as a result of breeding animals, growing various crops, storing waste, maintaining green areas in the public sector or recycling waste waters. An important mechanism for effective utilization of energy and biomass energy, in particular, is communal energy planning. Municipalities, micro-regions and regions should develop and strategically consider systems for utilizing separate energy sources, including biomass. For this reason, modern ecologically-oriented energy production technologies are of great importance for the local economies of each particular region and also lead to improvement of their ecological balance. With reference to this, it is necessary to make a timely assessment of the effectiveness and potential for electricity production form biomass in Bulgaria.
