    O processo de escolha do município de Juiz de Fora como local para instalação da montadora de automóveis Mercedes-Benz

    Dissertação (mestrado) - Universidade Federal de Santa Catarina, Centro Sócio-Econômico. Programa de Pós-Graduação em EconomiaEsta dissertação discute o processo de escolha do município de Juiz de Fora para implantação da montadora de automóveis Mercedes-Benz, na segunda metade da década de 90. Para isto, utiliza-se da idéia de modificação de paradigma produtivo proposto pelos autores neoschumpeterianos e toma-se o método avançado de produção enxuta, elaborado pela indústria japonesa, como o formato de produção perseguido. Faz-se uma análise da década de 90, onde verifica-se que, em função da abertura ao mercado externo, o setor automobilístico nacional é obrigado a passar por significativas transformações para se tornar mais competitivo e não vir a perder mercado para os concorrentes internacionais, cada vez mais presentes no mercado nacional. Posteriormente, analisa-se o modelo de vantagens competitivas. Por fim, demonstra-se a relação entre o Modelo de Vantagens Competitivas de Porter com o processo de escolha, além de apresentar alguns efeitos pós-instalação da montadora no município de Juiz de Fora, concluindo-se que os resultados obtidos apresentam-se aquém da perspectiva e do anúncio realizado, tanto pela empresa quanto pelo município, no que se refere à elevação do desenvolvimento regiona

    3-(1H-BENZ[d]IMIDAZOL-2-IL)PROPAN-1-OL VA UNING NITRATLI TUZINING MOLEKULYAR VA KRISTALL TUZILISHI

    3-(1H-benz[d]imidazol-2-yl)propan-1-ol which has potential biological activity, can be used as a ligand for complexation with metals. This compound is an electron donor, due to the lone pair of the nitrogen atom in the imidazole ring. This nitrogen atom also acts as a proton acceptor. In the crystalline phase, the nitrate salt, namely, 3-(1H-benz[d]imidazolium-2-yl)propan-1-ol nitrate, (C10H13N2O+•NO3-), has been studied. The protonation of the 3-(1H-benz[d]imidazol-2-yl)propan-1-ol unit results in significant delocalization of the electron density within the imidazole ring. The salt formation leads to variations in the intermolecular interactions, which were studied by analysis of the Hirshfeld surfaces and two-dimensional fingerprint plots.Соединение 3-(1H-бенз[d]имидазол-2-ил)пропан-1-ол представляет интерес благодаря своей потенциальной биологической активности и способности выступать в качестве лиганда для металлов. Атом азота в имидазольном кольце проявляет свойства как донора электронов (за счет неподеленной электронной пары), так и акцептора протонов. Исследование нитратной соли этого соединения, 3-(1H-бенз[d]имидазолиум-2-ил)пропан-1-ол нитрата (C10H13N2O+ NO3), показало, что протонирование бензимидазольной части вызывает значительное перераспределение электронной плотности в имидазольном кольце и приводит к изменениям в межмолекулярных взаимодействиях, которые были проанализированы с использованием поверхностей Хиршфельда и двумерных отпечатков пальцевPotensial biologik faollikka ega bo‘lgan 3-(1H-benz[d]imidazol-2-il)propan-1-ol metallar bilan kompleks hosil qilish uchun ligand sifatida ishlatilishi mumkin.

    BENZ WS: The Bologna ENZyme Web Server for four-level EC number annotation

    No full text
    The Bologna ENZyme Web Server (BENZ WS) annotates four-level Enzyme Commission numbers (EC numbers) as defined by the International Union of Biochemistry and Molecular Biology (IUBMB). BENZ WS filters a target sequence with a combined system of Hidden Markov Models, modelling protein sequences annotated with the same molecular function, and Pfams, carrying along conserved protein domains. BENZ returns, when successful, for any enzyme target sequence an associated four-level EC number. Our system can annotate both monofunctional and polyfunctional enzymes, and it can be a valuable resource for sequence functional annotation

    MeSH term explosion and author rank improve expert recommendations

    No full text
    Information overload is an often-cited phenomenon that reduces the productivity, efficiency and efficacy of scientists. One challenge for scientists is to find appropriate collaborators in their research. The literature describes various solutions to the problem of expertise location, but most current approaches do not appear to be very suitable for expert recommendations in biomedical research. In this study, we present the development and initial evaluation of a vector space model-based algorithm to calculate researcher similarity using four inputs: 1) MeSH terms of publications; 2) MeSH terms and author rank; 3) exploded MeSH terms; and 4) exploded MeSH terms and author rank. We developed and evaluated the algorithm using a data set of 17,525 authors and their 22,542 papers. On average, our algorithms correctly predicted 2.5 of the top 5/10 coauthors of individual scientists. Exploded MeSH and author rank outperformed all other algorithms in accuracy, followed closely by MeSH and author rank. Our results show that the accuracy of MeSH term-based matching can be enhanced with other metadata such as author rank

    Going Beyond Counting First Authors in Author Co-citation Analysis

    No full text
    The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

    Thermal Reduction of 7<i>H</i>-Benz[<i>d,e</i>]anthracen-7-one and Related Ketones under Hydrogen-Transfer Conditions

    No full text
    In the presence of hydrogen donor solvents and at elevated temperatures, aromatic ketones can be selectively deoxygenated to the corresponding hydroaromatic compounds. The kinetics for reduction of 7H-benz[d,e]anthracen-7-one (benzanthrone, 6) into 7H-benz[d,e]anthracene (benzanthrene, 1) in 9,10-dihydroanthracene (3) solvent has been investigated in detail. The relatively slow hydrogenation of 6 is due to reversibility of the initial hydrogen-transfer step according to a reverse radical disproportionation (RRD). The dynamics could well be rationalized using the energetics of species computed by density functional theory (DFT). The application of hydrogen donors such as 1 as a hydrogen-transfer agent, although favorable in terms of a low benzylic carbon−hydrogen bond dissociation enthalpy, is limited due to the slow self-hydrogenation, which in case of 1 gives 5,6-dihydro-4H-benz[d,e]anthracene (7)
