A Field of Study Spatial Economy in West Pomeranian University of Technology, Szczecin - Experiences and New Challenges
Zachodniopomorski Uniwersytet Technologiczny w Szczecinie to uczelnia publiczna utworzona 1 stycznia 2009 r. [Ustawa 2008] z połączenia dwóch najstarszych szczecińskich uczelni, tj. Politechniki Szczecińskiej powstałej w 1946 r. jako Wyższa Szkoła Inżynierska oraz Akademii Rolniczej powstałej w 1954 r. jako Wyższa Szkoła Rolnicza w Szczecinie. Jest to pierwszy przykład fuzji uczelni publicznych, którą prawnie umożliwiła obowiązująca od 2005 r. Ustawa Prawo o szkolnictwie wyższym [Ustawa 2005]. Zgodnie z treścią tej ustawy nowa uczelnia została uznana jako tzw. uniwersytet przymiotnikowy i zaliczona do grupy uczelni technicznych [Klasyfikacja… 2016]. Zachodniopomorski Uniwersytet Technologiczny w Szczecinie przejął pracowników i cały majątek oraz strukturę uczelni macierzystych i w ten sposób składa się z 10 wydziałów, które mają łącznie 13 uprawnień do nadawania stopnia naukowego doktora habilitowanego oraz 19 uprawnień do nadawania stopnia doktora. Jednym z celów fuzji uczelni była osiągnięcie efektu synergii potencjału naukowego i dydaktycznego w stosunku do obu macierzystych uczelni [Strategia 2012]. Oceniając to z perspektywy ponad 7 lat, został on osiągnięty, o czym świadczą m.in. wyniki w rankingach uczelni krajowych oraz we współpracy z biznesem [Perspektywy… 2015; Informacja… 2016].Spatial Economy as a field of study realised the Faculty of Environmental Management and Agriculture of the West Pomeranian University of Technology, Szczecin, is presented in the paper. This University was created in 2009, January, 1st as a fusion of two public universities with strong traditions: Technical University of Szczecin and Agriculture University of Szczecin. The program of study was formulated by Program Board of the land management course, accepted by the Faculty Board in 2011, and implemented in 2011/2012. Reflections of the teachers of economic and natural science courses are presented. Basing upon the accumulated experiences the factors favourably influencing students’ involvement were identified. The motivators, which could increase the involvement of students, and thus, increase the satisfaction from the education process in the field of Spatial Economy study are discussed
Ensemble Averages Calculated for Two-Dimensional Smoluchowski-Debye Rotational Diffusion in DC Electric Field
Ensemble averages ⟨cos nϑ(t)⟩ (n = 1, 2, 3, 4) are calculated for the two-dimensional Smoluchowski-Debye rotational diffusion model in the presence of a DC reorienting electric field. The time dependence of ⟨cos nϑ(t)⟩ is plotted for the special cases of (i) dipolar nonpolarizable molecules (p ≠ 0), and (ii) nondipolar anisotropically polarizable molecules (p = 0) and rectangular reorienting pulses
Do high iron concentrations in rewetted rich fens hamper restoration?
In this study we address the question of the extent to which iron may be a limiting factor in restoring rich fens in the temperate climate zone of Europe. Rewetted fens that were heavily degraded in the past by draining over a long period, were compared with pristine fens or fens with slightly altered hydrological systems. The chemical composition of peat and of pore water was analysed and related to the composition of the vegetation of the fens. The species composition and chemistry of the topsoil of restored fens differed markedly from that of the other fens, while the chemistry of the pore water from deeper layers showed only minor differences. Multivariate analysis revealed that differences in species composition between both categories were strongly related to the concentration of Fe in the pore water in the topsoil. Restored sites with high iron concentrations in the pore water (> 100 mu mol.L-1) lacked many vascular plants and mosses typical of peat forming fens. Iron and inorganic phosphorus pools in the topsoil of most restored fens were much greater than in the reference fens. A higher soil phosphorus pool originated mainly from the iron-bound fraction. We conclude that these differences are strongly governed by local processes and not by regional differences in climate, which were associated with geographical distribution of the different fens studied. The strong accumulation of iron and phosphorus in restored fens is attributed to a long history of drainage, which enhanced the accumulation of oxidized iron in the topsoil and also lowered the concentrations of calcium, magnesium and sulphur through drainage-caused reoccurring oxidation-reduction and leaching processes. A high iron and associated high phosphorous content appears to be an important and possibly irreversible bottleneck to restoring biodiversity and accumulation of peat with a low degree of humification in degraded fens. If a degraded fen has a low iron content then it is more likely to be restorable
