Spektrofotometrycznie i potencjometrycznie wyznaczano trwałość kompleksów Co(II), Ni(II) i Cu(II) stosując następujące kwasy jako ligandy: octowy, propionowy, masłowy, walerianowy oraz ich hydroksylowe pochodne. Uzyskane wyniki przedyskutowano w korelacji ze stałymi dysocjacji pKa odpowiednich kwasów oraz możliwością koordynacji poprzez gruę OH-.

The stability of Co(II), Ni(II) and Cu(II) complexes was determined spectrphotometrically and potentiometrically using the following acids as ligands: acetic, propionic, butyric, valeric and hydroxy derivatives of these acids. The obtained results were correlated with the pKa values of the above mentioned acids and possible additional coordination trough an OH- group.

When a municipal council enacts local spatial development plan or its changes, the result may be an increase in real property value. And if such property is sold by an owner or its perpetual usufructuary in five years since the zoning plan or its changes are in force, a head of the commune or a city mayor are obliged to levy the so-called zoning fees. It is a one-time payment related to increase in real estate value due to resolution or change of local development plan, determined by the provisions of the Spatial Planning and Development Act of 27 March 2003. This study aims at presenting theoretical and practical aspects concerning zoning fees. The proceedings carried out in Kraków with regard to real properties under two local development plans: Opatkowice West and Opatkowice East have been analysed. Moreover, the article examines the impact of the amendment to the Spatial Planning and Development Act adopted on 10 August 2011, to embrace the judgement of the Constitutional Tribunal of 9 February 2010, file no. P 58/08. The analyses are based on data acquired from The Geodesy Department of the Kraków City Office.

Uchwalenie przez radę gminy miejscowego planu zagospodarowania przestrzennego lub jego zmiana może spowodować wzrost wartości nieruchomości. Wówczas zbycie nieruchomości przez właściciela lub użytkownika wieczystego w terminie 5 lat od dnia, w którym plan miejscowy albo jego zmiana stały się obowiązujące, obliguje wójta, burmistrza albo prezydenta miasta do pobrania tzw. renty planistycznej (ew. opłaty planistycznej). Jest to jednorazowa opłata z tytułu wzrostu wartości nieruchomości spowodowanego uchwaleniem bądź zmianą planu miejscowego, ustalana zgodnie z przepisami ustawy z dnia 27 marca 2003 r. o planowaniu i zagospodarowaniu przestrzennym. Niniejsze opracowanie ma na celu przedstawienie teoretycznych i praktycznych aspektów dotyczących renty planistycznej. Analizie poddano postępowania prowadzone w Krakowie dla nieruchomości objętych ustaleniami dwóch planów miejscowych: Opatkowice-Zachód i Opatkowice-Wschód. W artykule przeanalizowano również wpływ nowelizacji ustawy o planowaniu i zagospodarowaniu przestrzennym, która weszła w życie z dniem 10 sierpnia 2011 r., mającej na celu uwzględnienie treści wyroku Trybunału Konstytucyjnego z dnia 9 lutego 2010 r. sygn. akt P 58/08. Podstawę analiz stanowiły dane uzyskane z Wydziału Geodezji Urzędu Miasta Krakowa.

Land consolidation procedures are an attempt to comprehensively change the existing spatial structure of land in rural areas. This treatment also brings many other social and economic benefi ts, contributing to the development of consolidated areas. Land consolidation in mountain areas differs in many respects from those implemented in areas with more favorable conditions for the functioning of agriculture. The unfavorable values of land fragmentation indices, terrain conditions and lower than the average soil quality affect both the dominant forms of agricultural activity and the limited opportunities to improve the distribution of plots in space, parameters of shape, and the area as a result of land consolidation. For this reason, the effectiveness of land consolidation in mountain areas can be achieved by improving the quality of transportation network and the accessibility of the plots, arranging ownership issues and improving the quality of cadastral documentation. This article presents the evaluation of the measures of effectiveness of land consolidation realized in mountain areas on the example of Łetownia Village in the Małopolska Province, located in the southern part of Poland. Selected village is an area with unfavorable conditions for the functioning of agriculture and high values of land fragmentation indices.

In our earlier investigations we showed, for the first time, with numerous practical examples that α-substituted propionic acids dissolved in the low-molecular-weight solvents are able to undergo spontaneous oscillatory in-vitro chiral conversion. In this study, we focused on attempting to suppress the spontaneous oscillatory in-vitro chiral conversion of α-substituted propionic acids using, as example, L -lactic acid dissolved in water in the presence of copper(II) cations. Our intention was to check whether the coordinate covalent bonds between copper(II) and L -lactic acid ligands prevented the latter species from oscillatory chiral conversion. To do this we stored aqueous solutions of copper(II) acetate and lactic acid in the molar ratios 1:1, 1:2, and 1:3 for a long period of time. Scrutiny of possible chiral conversion of L -lactic acid was carried out by thin-layer chromatography (TLC), polarimetry, and circular dichroism (CD) spectroscopy. Seemingly contradictory results were obtained from our investigations. From the TLC data it was apparent that chelating of copper(II) cations with L -lactic acid molecules did not result in suppression of the spontaneous oscillatory in-vitro chiral conversion of the acid. It was also established that different molar proportions of copper(II) cation and L -lactic acid molecules had somewhat different effects on the dynamics of conversion. In contrast, from polarimetric and circular dichroism studies it was apparent that when L -lactic acid is dissolved in water in the presence of copper(II) cations almost no chiral conversion is observed. Hence a final conclusion was drawn that chelating of copper(II) cations with L -lactic acid stabilizes the chiral structure of the acid in solution. Intermolecular interactions between the copper(II)-L -lactic acid complex and the silica gel stationary phase evidently affects the structure of the complex, however, most probably resulting in partial "liberation" of L -lactic acid ligands. Thus the chiral structure-stabilizing effect of copper(II) cations is apparently weakened by the TLC system and the freed L -lactic acid molecules can undergo chiral conversion.
