Bibliotecas digitais em Arquitetura e urbanismo: um estudo sobre a arquitetura da informação digital

The goal of this paper was to search the state of the art from the Digital Libraries in Architecture and Urbanism in the Higher Education Institutions (IES) through conceptualizations and showing the importance of Digital Libraries in the disclosure and easing of information transferring. Questions about digital information architecture, usability, digital preservation and accessibility were approached. The research was made in the websites of Brazilian Universities, firstly to identify the institutions which offered the Architecture and Urbanism course, focusing on postgraduate education. After identifying the offering, the research was done by analyzing the contents, storage and dissemination and access to information, these libraries. It was found that the digital libraries are increasingly and taking part of organizations and educational institutions focusing on the knowledge dissemination releasing digitally information that may be needed for institution or the individual. A monitoring was done over of the physical and computational restructuring of the Board of Studies and Research in Architecture and Urbanism (Câmara de Estudos e Pesquisa em Arquitetura e Urbanismo, CEPAU), from the Architecture and Urbanism Course of the Federal University of Rio Grande do Norte (UFRN), showing the need of installing a Digital Library to integrate the databases of PPGAU s research groups, which today remain independent, with no interface among themselves. The research chosen area was Architecture and Urbanism, because there is a gap and little documentation about digital libraries in this area

CONSORCIOS DE BIBLIOTECAS UNIVERSITARIAS CENTROAMERICANAS: REDSIID

Con el fin de participar en el debate que sobre consorcios se ha generado en la actualidad, se presenta en este documento una descripción de la experiencia de lo actuado en la Red de Sistemas Integrados de Información Documental de las Universidades miembros del Consejo Superior Universitario Centroamericano REDSIID/CSUCA; la cual pretende ser un consorcio académico bibliotecológico. Estructura de cooperación que podría favorecer a la región centroamericana.La globalización ha generado un estado de confrontación entre las corrientes de pensamiento. La formación académica tiende a ser más horizontal dejando de lado las élites intelectuales. Sin embargo, esa horizontalidad, que permite igualdad de acceso a todos los grupos sociales y a todos los niveles culturales, transgrede las identidades locales y a las universidades. La misma autonomía universitaria pareciera perder vigencia, para ampliar los espacios de convivencia y retroalimentación comunitaria; uno de ellos, establecer vínculos universidad-empresa. Consecuentemente, el modelo universitario debe reconceptualizar sus procesos, entre ellos: el acceso a la información, el acceso al conocimiento y el acceso al aprendizaje.

Caracterização funcional de dois cDNAs homólogos à ciclofilina e à proteína reprimida por auxina (ARP) identificados em bibliotecas subtrativas a para floração em tomateiro

Flowering is a fundamental process in the life cycle for plant. This process is marked by vegetative to reproductive apical meristem conversion, due to interactions between several factors, both internal and external to plant. Therefore, eight subtractive libraries were constructed using apical meristem induced or not induced for two contrasting species: Solanum lycopersicum cv. Micro-Tom and Solanum pimpinellifolium. Several cDNAs were identified and among these, were selected two cDNAs: one homologous cDNA to cyclophilin (LeCYP1) and the other to Auxin repressed protein (ARP). It has observed that LeCYP1 and ARP genes are important in the developmental process to plants. In silico analysis, were used several databases with the exclusion criterion E-value <1.0x10-15. As a result, conservation was observed for proteins analyzed by means of multiple alignments and the presence of functional domains. Then, overexpression cassettes were constructed for the ARP cDNA in sense and antisense orientations. For this step, it was used the CaMV35S promoter. The cDNA orientation (sense or antisense) in relation to the promoter was determined by restriction enzymes and sequencing. Then, this cassette was transferred to binary vector pZP211 and these cassettes were transferred into Agrobacterium tumefaciens LBA4404. S. lycopersicum cv. Micro-Tom (MT) and MT-Rg1 plants were transformed. In addition, seedlings were subjected to hormone treatments using a synthetic auxin (- naphthalene acetic acid) and cyclosporin A (cyclophilin inhibitor) treatments and it was found that the hormone treatment there were changes in development of lateral roots pattern, probably related to decreases in auxin signaling caused by reduction of LeCYP1 in MT-dgt plants while cyclosporin A treatments, there was a slight delay in flowering in cv. MT plants. Furthermore, assay with real-time PCR (RT-qPCR) were done for expression level analysis from LeCYP1 and ARP in order to functionally characterize these sequences in tomato plants.

A emergência da qualidade nas Bibliotecas Públicas em Portugal

Este estudo apresenta um diagnóstico de situação das Bibliotecas Públicas portuguesas face aos Sistemas de Gestão de Qualidade (SGQ) e a avaliação de indícios de emergência de qualidade neste tipo de bibliotecas, tipificando os diferentes tipos de emergência diagnosticados, identificando os factores que impulsionam a implementação dos SGQ, os motivos de recuo e/ou avanço para uma gestão de qualidade. É estabelecida a ligação ao percurso da qualidade na Administração Pública em Portugal, com vista a contextualizar o presente trabalho e entender o aparecimento de Sistemas de Gestão de Qualidade. Apresentam-se razões que justificam a lentidão da prevista e anunciada proliferação de Sistemas de Gestão de Qualidade nas Bibliotecas Públicas portuguesas (como se previa há uma década atrás), referenciando de forma sucinta alguns dos diferentes modelos de gestão de qualidade validados que se encontram implementados tanto no nosso país como no estrangeiro. ABSTRACT: This study presents a diagnostic explanation on the situation of the Portuguese Public Libraries, taking into consideration the system of Managenent Quality Control (SGC) and the evaluation of the emergence of quality in these types of libraries, typifying the different types of forthcoming diagnostics, identifying the factors that started the implementation of the SGC and the reasons of the withdrawal and advancement towards quality management. A synopsis of the quality of Public Administration in Portugal has also been made, with the idea of putting into context the current work and understanding up to what point this forced the arrival of the system of Management Quality Control and, in a way, try to find the reasons that justify the slowness of the arrival of the system of Management Quality Control in the Portuguese Public Libraries (as was predicted almost a decade ago). Throughout this document references and explanations will be made, in a succinct way, of some of the different forms of validated Quality Management Control that are to be found in our country, as well as abroad.

Homogeneidade e heterogeneidade nos sistemas educacionais: Argentina, Brasil, Chile e México

This study focus on the reconfiguration of educational management in Argentina, Brazil, Chile and Mexico, which was promoted by the new logic of social regulation and the new role attributed to the State, considering each country's own historicity. So, the cultural factors that interfere on the dynamics of the 90' school reform are analyzed. Aspects that show the homogeneity or heterogeneity of these reforms in the region, as well as local specificities that block out the concretization of the reform are underlined. It is shown that the historicity that characterizes the educational reform has taken, in each country, a form that can be called, in Mexico, conservative rupture; in Chile, conservative continuity; in Brazil, conservative renovation; and, in Argentina, interrupted rupture. Some conclusions about the impact of educational reform in the selected countries are recuperated through the analysis of 186 academic texts on the subject.

Sistemas aquosos bifásicos: fundamentos e aplicações para partição/purificação de proteínas

By the year 2005 the world biochemical market will reach an estimated $ 100 billion and separation processes are a vital link between lab discoveries and the fulfillment of this commercialization potential. The practical application of aqueous two-phase systems (ATPS) to extraction processes has been exploited for several years for the recovery of biological products. Unfortunately, this has not resulted in an extensive presence of the technique in commercial processes. In this paper a critical overview of the fundamental thermodynamic properties related to formation of aqueous two-phase systems and their application to extraction and purification of bioparticules is presented.

Sistematização do dimensionamento técnico e econômico de sistemas fotovoltaicos isolados por meio de programa computacional

One of the main referring subjects to the solar energy is how to compare it economically with other sources of energy, as much alternatives as with conventionals (like the electric grid). The purpose of this work was to develop a software which congregates the technical and economic main data to identify, through methods of microeconomic analysis, the commercial viability in the sizing of photovoltaic systems, besides considering the benefits proceeding from the proper energy generation. Considering the period of useful life of the components of the generation system of photovoltaic electricity, the costs of the energy proceeding from the conventional grid had been identified. For the comparison of the conventional sources, electric grid and diesel generation, three scenes of costs of photovoltaic panels and two for the factor of availability of diesel generation had been used. The results have shown that if the cost of the panels is low and the place of installation is more distant of the electric grid, the photovoltaic system becomes the best option.

Teores de nutrientes na alface irrigada com água residuária aplicada por sistemas de irrigação

A trial was carried out to evaluate the chemical composition in the aerial part of lettuce, cv. 'Elisa', irrigated with wastewater treated with constructed wetland and source deposit water, grown on a Rhodic Hapludox Soil, using the irrigation systems sprinkle, subsurface drip and surface drip irrigation. The experiment was carried out from August 17th to October 3rd of 2001 and the chemical analyses of the lettuce were accomplished to 47 days after transplanting of the seedling. The aerial part of the lettuce was analyzed as for the levels of total nitrogen, nitrate, phosphorus, potassium, calcium, magnesium, sulfur, iron, manganese, copper, zinc, sodium, boron, cobalt and molybdenum. The sodium and the sulfur presented higher levels than the maximum suitable in the aerial part of the lettuce and the smallest level of magnesium, while other chemical elements analyzed were normal and appropriate considering the standard for well-nourished plants, not being influenced by the water type. The sodium was the chemical element that presented the highest levels in the aerial part of the lettuce in the treatments irrigated with wastewater, presenting significant difference in relationship to the treatments irrigated with source deposit water in the three irrigation systems. The use of the different irrigation systems by the application of wastewater treated with constructed wetland did not interfere in the levels of nutrients in the aerial part of the lettuce.
