The Wrocław University of Economics is one of ten public universities located in Wrocław, Poland. Originally established in 1947 as a private business school , it was nationalized in 1954 under the name Wyższa Szkoła Ekonomiczna, "College of Economics"). In October 1974 it was named after the Polish economist Oskar Lange, although his name does not occur in the official English name of the university. Changing the name to the Wrocław University of Economics in 2008 removed Oskar Lange from the name of the University.The main campus with three out of four departments is located on Ulica Komandorska near the center of Wrocław, whereas one faculty resides in a separate campus in Jelenia Góra.The university comprises the following schools :School of Economic scienceSchool of Engineering and EconomicsSchool of Management, Computer Science and FinanceSchool of Regional Economy and Tourism Altogether it employs 784 academic teachers including 142 professors. There is strong interest in economic studies, in the current academic year the University has about 17,000 students, and so far it has produced over 70,000 graduates. Wikipedia.

The subject of these considerations is to show the role of integrated order category in refinement of the new paradigm of development. This paradigm is being introduced as sustainable, durable, self-sustaining, or eco-development. The article is trying to answer two important questions: first - Is sustainable development as legal representative of this new paradigm enough developed concept of development? Secondly - what is the role of integrated order in this refinement? Integrated order is here understood as benchmarking essence of sustainable development, as positive target of developmental changes merging in consistent way different orders: economic, social (including institutional-political) and environmental (including spatial). As minimal axiological level of orders formation moderate anthropocentrism was indicated. Ways of consideration and decoding sustainable development as integrated order vary depending on scientific field and discipline. The article is showing this phenomenon on the example of few scientific research centers. Source

The Multiobjective Evolutionary Algorithm Based on Decomposition (MOEA/D) is a very efficient multiobjective evolutionary algorithm introduced in recent years. This algorithm works by decomposing a multiobjective optimization problem to many scalar optimization problems and by assigning each specimen in the population to a specific subproblem. The MOEA/D algorithm transfers information between specimens assigned to the subproblems using a neighborhood relation. In this paper it is shown that parameter settings commonly used in the literature cause an asymmetric neighbor assignment which in turn affects the selective pressure and consequently causes the population to converge asymmetrically. The paper contains theoretical explanation of how this bias is caused as well as an experimental verification. The described effect is undesirable, because a multiobjective optimizer should not introduce asymmetries not present in the optimization problem. The paper gives some guidelines on how to avoid such artificial asymmetries. © 2014 Elsevier B.V. All rights reserved. Source

The molecular structure of 2-N-ethylamino-5-methyl-4-nitropyridine (EN5MP) and its vibrational spectra have been analyzed in terms of quantum chemical DFT calculations (B3LYP/6-311++G(d,p) approaches) and related to the XRD data. The EN5MP crystal is triclinic and centrosymmetric and its unit-cell is built by asymmetric units consisting of two parallelly arranged formula units, 2[C 8H 11N 3O 2], of different conformations. In each of the two subunits the methyl carbons and N-atoms of the nitro group are coplanar with the pyridine ring, but the O-atoms are inclined from this plane in the opposite directions. Dimers are linked by intermolecular NH⋯N hydrogen bonds system. Properties of the N AH⋯ N P interactions between the hydrogen atom of the pyridine ring N P and the hydrogen atom of the amino group N A have been characterized. Additionally the crystal structure is stabilized by a set of weak intermolecular CH⋯O interactions. © 2012 Elsevier B.V. Source

The paper presents the economic and technical problems associated with the use of biomass in co-combustion processes in the energy sector in Poland. The particular attention was paid to the extent of the use of biomass in the energy sector, the technologies and techniques applied, as well as the economic determinants. As it results from the analyses, the co-combustion of biomass in Poland is a predominant direction in the "green" energy production. Co-combustion processes are carried out mainly with the use of direct combustion technologies in the largest entities operating in the energy market. The widespread use of biomass in the Polish energy sector results in specific problems, such as those associated with the prices of green certificates and the import of biomass. Currently, the Polish renewable energy sector is developing as intended. However, the validity of the funds spending, which aimed at supporting renewable energy sources (RES), may raise some doubts. This results from insufficient monitoring of the amount of energy produced on the basis of renewable sources, which in 2012 led to over-production of the RES-based energy and, consequently, to a significant decrease in prices of green certificates. © 2015 Elsevier Ltd.

A diagram representing phase relationships in the Sr3(PO 4)2-CePO4 phosphate system has been developed on the basis of results obtained by thermal analysis (DTA/DSC/TGA) and X-ray diffraction (XRD) methods. One intermediate compound with the formula Sr 3Ce(PO4)3 occurs in the Sr3(PO 4)2-CePO4 system at temperatures exceeding 1045 °C. The compound has a eulytite structure with the following structural parameters: a=b = c= 10.1655(8)Å, α=β=γ=90.00°, V = 1050.46(6)Å3. It's melting point exceeds 1950 °C. A limited solid solution exists in the system, which possesses the structure of a low-temperature form of Sr3(PO4)2. At 1000 °C the maximal concentration of CePO4 in the solid solution is below 20 mol%. The solid solution phase field narrows with increased temperature. There is a eutectic point in the {Sr3(PO 4)2+Sr3Ce(PO4)3} phase field at 1765 °C and 15 mol% of CePO4. The melting temperature of Sr3(PO4)2 is 1882 + 15 °C. © 2013 Elsevier Inc. All rights reserved.
