A pesquisa aborda o uso das Tecnologias de Informação e Comunicação, que vem revolucionando as atividades e ocasionando muitas mudanças relacionadas ao acesso e uso de informações. O objetivo foi analisar o grau de utilização do conhecimento científico produzido pelos Programas de Pós-Graduação das Universidades Públicas Brasileiras, através da BDTD, pelos mestrandos dos referidos programas. Nos procedimentos metodológicos realizados, procurou-se inicialmente analisar o amplo espectro da população do corpus da pesquisa. Em razão da impossibilidade de trabalhar com os Programas de Pós-Graduação como um todo, optou-se por fazer um recorte, elegendo os cursos de Pós-Graduação em Ciência da Informação, vez que estes representam o principal segmento social de interesse da pesquisa. Foi utilizado o método de estudo de usuários, onde se optou por adotar o grupo, “estudos orientados aos usuários”, que identifica as necessidades e comportamento de acesso e uso da informação. Para coletar os dados, elaborou-se um questionário semi-estruturado com 25 questões, que versavam sobre o uso, dificuldades de acesso e recuperação da informação, bem como a satisfação na utilização dessa fonte informacional. Dentre os vários resultados obtidos, podemos destacar o fato de que a maioria dos mestrandos (71,8%) só teve contato com a BDTD somente no momento em que se encontrava cursando o mestrado e, somente 24,3%, tiveram contato durante a graduação. Estes resultados representam um problema, que pode afetar o bom desempenho do projeto BDTD, o qual consiste em disseminar e divulgar a produção científica dos Programas de Pós-Graduação das Universidades Públicas Brasileiras para a sua comunidade. Foi observado também, que os mestrandos oriundos do curso de Biblioteconomia tende a ter contato com a BDTD bem mais cedo do que mestrandos de outros cursos de graduação. A fim de minimizar o problema detectado, propõe-se uma divulgação mais eficaz na graduação através de dois procedimentos: Primeiro, o docente deve fazer uma divulgação mais eficaz da BDTD junto aos discentes de todos os cursos de graduação; segundo: deverá ser feita a divulgação na mídia eletrônica, através da inserção de ícones da BDTD, nos portais dos Departamentos dos Cursos de Graduação das Universidades Públicas Brasileiras. Acredita-se que com estes procedimentos seja possível aperfeiçoar o uso dessa fonte de informação científica.

Na observação prática cotidiana da Biblioteca Central Zila Mamede (BCZM), procurou-se identificar o comportamento dos usuários com relação ao uso das informações disponibilizadas. É bem possível que os usuários não se interessem pelos serviços por não conhecê-los plenamente. Tais observações levaram aos seguintes questionamentos: a) a comunidade acadêmica da Universidade Federal do Rio Grande do Norte (UFRN) sabe da existência de todas as fontes de informação disponibilizadas para pesquisa nessa unidade informacional? b) O desinteresse por algumas dessas fontes de informação tem relação com o desconhecimento das mesmas? Estes questionamentos motivaram a realização de um projeto que tem como objetivo divulgar as formas de acesso à produção científica da UFRN. Esse artigo descreve os serviços oferecidos pela BCZM, através da Literatura de Cordel, com a finalidade de estimular e sensibilizar os alunos de graduação, pós-graduação, professores e funcionários sobre a importância do acesso ao conhecimento científico disponíveis na biblioteca, acredita-se que a Literatura de Cordel, por ser um suporte informacional que alcança desde mercados e feiras, divulga a arte, a ciência e as tradições populares, ajuda, também, na disseminação das informações e estimula o prazer pela leitura. Tais requisitos capacita a nossa Comunidade Acadêmica, bem como o público em geral, o qual terá acesso às informações relevantes que servirão de insumos na construção do conhecimento. Neste artigo, serão apresentados em versos e estrofes escritos em forma rimada, os serviços que a BCZM oferece à sua comunidade. Posteriormente, serão divulgados outros serviços e as formas de acesso à produção científica da UFRN.

The text came from the UNESP-Project in Partnership with the Public Administration: City of Echaporã ‖, a multidisciplinary project, interdepartmental and that results from a term partnership signed between the State University / Campus Marilia, the Regional Office of Articulation Planning and the Municipality of Echaporã.Given the serious social problems diagnosed in this county Administrative Region of Marilia, somaramse forces and, since April 2002, Echaporã account with the performance of a design matrix that involves the community in six (6) subprojects, among which a which emphasizes the dissemination of information (the public library as a center of information and knowledge irradiator for urban and rural areas, seeking to enter the Society daInformação). By their nature, the project-matrix is considered open and can accommodate new subprojects, where they concern the problems identified in the initial diagnosis. For its validity, each subproject has its own methodology, some innovative and will be subject to further systematization and dissemination, however, after a few months of deployment, the results show the correctness of community involvement (being representative) in all discussions and steps of research, and activities developed, widely disseminated to the target audience. The membership of the community, the leaders and the authorities can be considered a good barometer of the actions carried out in Echaporã and evidence of change in information culture that is already noticeable in the city, setting the socio-cultural dynamics of the same, in terms a new public policy to be strengthened with the participation of specialists in this specific area, in direct work with local managers, in this case, specific examples relating to the strength of information in the process of change in small municipalities.

Worldwide, families Carangidae and Rachycentridae represent one of the groups most important commercial fish, used for food, and great potential for marine aquaculture. However, the genetic bases that can underpin the future cultivation of these species, cytogenetic between these aspects are very weak. The chromosomal patterns have provided basic data for the exploration of biotechnological processes aimed at handling chromosomal genetic improvement, such as induction of polyploidy, androgenesis and ginogenesis, as well as obtaining monosex stocks and interspecific hybridizations. This paper presents a comprehensive cytogenetic survey in 10 species, seven of the family Carangidae and the monotypic family Rachycentridae. Classical cytogenetic analysis and in situ mapping of multigene sequences were employed, and additionally for the genus Selene and morphotypes of Caranx lugubris, comparisons were made using geometric morphometrics. In general, conservative species exhibit a marked chromosome number (2n=48). Although present in large part, different karyotypic form, retain many characteristics typical of chromosomal Order Perciformes, the high number of elements monobrachyal, Ag-NORs/18S rDNA sites and heterochromatin simply reduced, preferably centromeric. The main mechanisms involved in karyotypic diversification are the pericentric inversions, with secondary action of centric fusions. In addition to physical mapping and chromosome detail for the species are presented and discussed patterns of intra-and interspecific diversity, cytotaxonomic markers. This data set provides a better understanding of these patterns caryoevolutyonary groups and conditions for the development of protocols based on Biotechnology for chromosomal manipulation Atlantic these species

Perciformes are dominant in the marine environment, characterized as the largest and most diverse fish group. Some families, as Gerreidae, popularly known as silver jennies, carapebas, or mojarras have a high economic potential to marine fish farming, natural explotation and game fishing. Genetic information of these species are of fundamental importance for their management and production. Despite exist over 13,000 marine fish species described, only 2% were cytogenetically analyzed and less than 1% have some reproductive characteristics known. Induced breeding, cytogenetic characterization and cryopreservation of gametes, represent important areas in applied fish studies. In this project cytogenetic analyzes were performed to acess genetic aspects of Gerreidae species, distributed in coastal and estuarine regions of Northeast Brazil. Different methods for identifying chromosomal regions were employed using conventional techniques (Ag-NORs, C-banding), staining with base-specific fluorochromes (DAPI-CMA3), and physical mapping of ribosomal genes 18S and 5S rDNA, through hybridization in situ with fluorescent probes (FISH). The six species analyzed showed remarkable chromosome conservatism. The 18S and 5S ribosomal genes when analyzed in phylogenetic perspective demonstrate varied evolutionary dynamics, suggesting ocurrence of stasis process in some groups and greater dynamism in others. Double FISH with 18S and 5S probes showed both how efficient cytotaxonomic markers in the homogeneous karyotypes of this group of species. The karyotypic pattern identified in addition to the evolutionary aspects of karyotype, are suggestive of existence of low potential of post-zygotic barrier, prompting further research to prospect for artificial interspecific hybridization of these species of commercial importance

The financial crisis that occurred between the years 2007 and 2008, known as the subprime crisis, has highlighted the governance of companies in Brazil and worldwide. To monitor the financial risk, quantitative tools of risk management were created in the 1990s, after several financial disasters. The market turmoil has also led companies to invest in the development and use of information, which are applied as tools to support process control and decision making. Numerous empirical studies on informational efficiency of the market have been made inside and outside Brazil, revealing whether the prices reflect the information available instantly. The creation of different levels of corporate governance on BOVESPA, in 2000, made the firms had greater impairment in relation to its shareholders with greater transparency in their information. The purpose of this study is to analyze how the subprime financial crisis has affected, between January 2007 and December 2009, the volatility of stock returns in the BM&BOVESPA of companies with greater liquidity at different levels of corporate governance. From studies of time series and through the studies of events, econometric tests were performed by the EVIEWS, and through the results obtained it became evident that the adoption of good practices of corporate governance affect the volatility of returns of companies

The Library of the Institute of Alajuela made an induction experience and training of users and ventured into the information literacy and engaged in the work of the teaching-learning as an integral part of the curriculum. The actions of the library in developing search strategies, location, selection and use of information brought inthe health service, changes to the role of the library, the librarian, the book and the information in the educational environment.By sharing this experience is intended to provide information that can motivate staff of educational institutions that wish toenter the field of information literacy as a strategy to support the development oflifelong independent learning skills and meaningful learning. Currently, the library should be a proactive part in the education of students but also teachers, administrative and family.This will result in a benefit to Costa Rica: the development of youth and their proper integration into the workplace.

Training in information competencies or information literacy is one of the current challenges of university libraries at the possibilities of access to vast information resources that facilitate digital media, which require a better understand and apply the selection and assessment criteria to retrieval the highest quality and relevance of information as needed. In this situation, Ibero-American university libraries (Latin-America, Spain and Portugal) have been slowly incorporating this training either from direct training programs, offered from the library or through collaborative work with teachers and schools in curricula of various universities as a whole or in specific disciplines. In this text, it was identified that, at present, from the information displayed on Web sites of universities-HEI in Costa Rica, a very small percentage of university libraries would find taking actions in a level 1 or 2 of incorporating information literacy, since a large most developed is still very focused programs and processes to the traditional user training, while another large majority, unfortunately, has no action-information about actions from the forming perspective that should be any library.

Con agrado, se presenta un nuevo número de la Revista Bibliotecas. Incluye investigaciones de interés acerca de los siguientes temas: arquetipos bibliotecarios, alfabetización informacional e informática en la nube. En el artículo dedicado a los arquetipos, el autor afirma que la profesión bibliotecológica, al igual que ocurre con otras disciplinas, está expuesta a una serie de estereotipos. Tales impresiones y creencias provocan que las personas, motivadas por el prejuicio, no incursionen en una fascinante disciplina; como consecuencia, inciden en la matrícula de estudiantes de primer ingreso. Este escrito expone la situación de la Escuela de Bibliotecología, Documentación e Información, de la Universidad Nacional, y plantea una propuesta didáctica en aras de mejorar la concepción de la bibliotecología entre la población estudiantil de secundaria.

One of the major current challenges for oilwell companies is the extraction of oil from evaporitic zones, also known as pre-salt basins. Deep reservoirs are found under thick salt layers formed from the evaporation of sea water. Salt layers seal the flow of oil from underneath rock formations, which store hydrocarbons and increase the probability of success in oil and gas exploration. Oilwells are cemented using Portland-based slurries to promote mechanical stability and zonal isolation. For pre-salt oilwells, NaCl must be added to saturate the cement slurries, however, the presence of salt in the composition of slurries affects their overall behavior. Therefore, the objective of the present study was to evaluate the effect of the addition of 5 to 25% NaCl on selected properties of Portland-based slurries. A series of tests were carried out to assess the rheological behavior, thickening time, free water and ultrassonic compressive strength. In addition, the slurries were also characterized by thermal analysis, X ray diffraction and scanning electron microscopy. The results showed that the addition of NaCl affected the thickening time of the slurries. NaCl contents up to 10% shortened the thickening time of the slurries. On the other hand, concentrations in excess of 20% not only extended the thickening time, but also reduced the strength of hardened slurries. The addition of NaCl resulted in the formation of a different crystalline phase called Friedel´s salt, where free chlorine is bonded to tricalcium aluminate
