Stoichiometric Complex

A stoichiometric complex of formula (COOH)2•2H2O•18-crown-6 has been obtained from oxalic acid and the macrocyclic polyether 18-crown-6. The crystals of the complex have a monoclinic unit cell and belong to the P21/c space group. The components in the adduct are linked through hydrogen bonds in a polymer-like fashion: -crown–H2O–HOOCCOOH–OH2–crown–, where the oxalic acid molecules are present in two distinct disordered orientations. The infrared and Raman spectra of the complex are also reported and interpreted.

Um coletivo em formação na área da Psicologia. A Instalação 18 de maio no campus de uma Universidade Pública. A Análise Institucional como temática de uma disciplina de teorias e técnicas de pesquisa em Psicologia. Esses três elementos construíram um campo onde as técnicas do Teatro do Oprimido e a construção conceitual das palavras geradoras, de Paulo Freire, problematizaram a produção da loucura a partir de uma pesquisa/intervenção. O trabalho aqui apresentado, que aborda questões-limite da desistitucionalização da loucura, possibilitou perceber como a sociedade construiu um espaço institucionalizado da doença mental que ultrapassa os muros dos manicômios formando subjetividades. A experiência com estudantes de Psicologia proporcionou um momento de formação profissional dialógico e de reflexão crítica das práticas sociais com os sujeitos encarcerados como 'desviantes da ordem', e, facilitou o aprendizado do manejo da teoria e das ferramentas da Análise Institucional, reafirmando uma importante perspectiva técnica de intervenção social.

Dzięki rozwojowi techniki nastąpił szybki rozwój transportu lotniczego w XX w., cospowodowało wzrost mobilności społeczeństwa, ułatwiło i przyspieszyło zmianę miejsca pobytu.Postęp ten wywołał wzrost liczby samolotów i linii lotniczych, zwiększył dostępność, szybkość, komfortprzelotu, bezpieczeństwo podróży oraz obniżenie kosztów. Budowa nowych regionalnych lotniski modernizacja istniejących skraca czas podróży i wydłuża wypoczynek. Rozwój portów lotniczychpociąga za sobą powstawanie wielu obiektów towarzyszących, świadczących usługi pasażerom.Kraków Airport to drugie co do wielkości lotnisko w Polsce. Jest skomunikowane z 90 miastami w 28krajach. Rocznie obsługuje około 3 milionów pasażerów. W pierwszym półroczu 2012 roku na krakowskimlotnisku obsłużono 1 606 861 osób. Jest to wynik o 18% lepszy niż w pierwszym półroczu2011 roku.Celem artykułu jest pokazanie – na przykładzie lotniska Kraków Airport – jak zmieniało się znaczeniei funkcje lotnisk regionalnych w Polsce i jak obecne zmiany w infrastrukturze transportu lotniczegomogą przyczynić się do rozwoju turystyki. Celem artykułu jest także przedstawienie liczby pasażerówkorzystających z lotniska, aktualnych kierunków połączeń krajowych, europejskich oraz czarterowych.Lotnisko w Balicach ukazane zostanie na tle innych polskich portów regionalnych. Prezentacja obejmierównież prognozy i plany rozbudowy. W podsumowaniu znajdzie sie omówienie implikacji dlarozwoju turystyki.

The structure of the crown ether 1,8-(3,6,9-trioxaundecane-1,11-diyldioxy)-9,10-dihydro-10,10-dimethylanthracene-9-ol, C24H30O6·H2O (1), code name P326, the parent compound for a series of derivatives, has been determined by both X-ray diffraction at room temperature and neutron diffraction at very low temperature. The unit cells are very similar at both temperatures and in both cases the crystals exhibit P21 symmetry with Z = 4 (two molecules, A and B, respectively, per asymmetric unit) and pseudosymmetry P21/c. The higher symmetry is broken mainly by the two independent water molecules in the unit cell, some reflections which would be absent in P21/c having strong intensities in both the X-ray and neutron data. In both molecules A and B hydrogen bonds involving the water molecule stabilize the macrocyclic ring structure, one involving the macrocyclic O(9) as a donor. Close contacts between the water and macrocyclic O atoms in each molecule also suggest the presence of two bifurcated hydrogen bonds, involving water HW2 to both O(16) and O(18), and water HW1 to both O(18) and O(20), respectively, with considerable variation in the geometry being present. Both molecules A and B exhibit very close pseudosymmetry across a plane perpendicular to the molecular plane and through atoms C(9) and O(18), and in addition are predominantly planar structures. The X-ray analysis failed to reveal one H atom per water molecule, each being subsequently included after location and refinement in the neutron analysis.

Stoichiometric Complex

A stoichiometric complex of formula maleic acid•2H2O•18-crown-6 has been obtained from maleic acid and the macrocyclic polyether 18-crown-6. Crystals of this complex have been shown by X-ray diffraction crystallography to belong to the Cc space group of the monoclinic system. The acid molecules in the adduct are linked to each other through a water molecule, giving infinite [-acid-H2O-]n chains. They are also linked to the crown ether via water molecules. The infrared and Raman spectra of the complex are presented and compared to those of crystalline maleic acid. Keywords: maleic acid/18-crown-6, structure, X-ray, spectra.
