3. Dureza Brinell y parámetros termofísicos de la Guadua angustifólia - Kunth
Guadua angustifolia-Kunth is a forest resource with special physical and mechanical characteristics, which is used mainly in houses building, laminates manufacture, and decorative items. Also it plays an important role in watershed protection, in the CO2 capture and soil conservation. The thermal and mechanical characterization of this type of biological mat

4. Efeitos da formação e operação de um reservatório de pequena regularização na alteração da qualidade da água e do regime hidrológico na planície de inundação do Pantanal
The formation of reservoirs changes the quality and quantity of water, both upstream and downstream, and the direction and magnitude of such changes depend on their characteristics of construction, operation, morphometry, as well as hydrological regime and climate of the region. However, much of this knowledge was based on large reservoirs, which is not the

6. STUDY OF THE PHYSICAL-CHEMICAL CHARACTERISTICS OF THE SOIL IN PARAGUAY TEA (Ilex paraguariensis St. Hil) THROUGH THE GEOSTATISTICS AND THE GEOPROCESSING / ESTUDO DAS CARACTERÍSTICAS FÍSICO-QUÍMICAS DO SOLO EM PLANTIO DE ERVA-MATE (Ilex paraguariensis St. Hil.) ATRAVÉS DA GEOESTATÍSTICA E DO GEOPROCESSAMENTO
This work was based in methods of classic descriptive statistics, methods of geostatistics and geoprocessing, in the identification of the size and the structure of the spatial variability of the physical and chemical attributes of the soil in area of Paraguay Tea forestry. The area of study, localized in the Tupian Farm, in the municipality of New Silver, R

7. Fertilizantes de leguminosas: tecnologia inovadora de adubação verde para provisão de nitrogênio em sistemas orgânicos de produção. / Legume fertilizers: innovative technology of green manuring for nitrogen supply in organic farming systems.
One of the main limitations to the organic food production is the reduced availability of low cost and efficient nitrogen (N) sources. Green manuring practices, in rotation or intercropped, have been used, but hardly are they able to supply crop needs. This dissertation presents an innovative technology of green manuring, derived of the cutting, dehydration

8. Resolução do problema de fluxo de carga para redes de distribuição utilizando o metodo desacoplado rapido com rotação automatica de eixos / Fast decoupled load flow method with automatic axes rotation for distribution systems
The fast decoupled loadflow (FDLF) [2] is a variant of the traditional Newton method [1] for solving the loadflow problem (find the operational state of electrical power networks). It is well-known that FDLF presents unsatisfactory performance when applied to distribution systems. Their unfavourable r/x branch ratios may lead to divergence or slow convergenc

9. DYNAMICS, KINEMATICS AND PHYSIOLOGICALS EFFECTS OF USING DIFFERENTS TYPES OS MAILBAGS / "Influência da mochila em parâmetros dinâmicos, cinemáticos e fisiológicos da locomoção de carteiros pedestres"
The aim of this study was to determine the influence of the satchel construction characteristics in selected biomechanical and physiological parameters during the accomplishment of the locomotion of mailmen pedestrians. 49 mailmen had been voluntary (30±7 years, 1.74±0.62 m and 72.6±11.8 kg), which had used 3 types of satchels, simple lateral satchel (MLS

10. A preferência pela prática de atividades físicas e esportivas: uma abordagem psicofísica / The preference for the practice of physical and sporting activities: an psychophysical analysis
A preferência pela prática de atividades físicas e esportivas é um atributo subjetivo de difícil mensuração e que tem sido um dos critérios fundamentais, na escolha e na decisão para a sua prática, nos dias atuais. Deste modo, a preferência pela prática de atividades físicas e esportivas foi investigada por meio de métodos psicofísicos escalar

11. 1998 SM165: A large Kuiper belt object with an irregular shape
The recent discovery of an ancient reservoir of icy bodies at and beyond the orbit of Neptune—the Kuiper belt—has opened a new frontier in astronomy. Measurements of the physical and chemical nature of Kuiper belt objects (KBOs) can constrain our ideas of the processes of planet formation and evolution. Our 1.8-m Vatican Advanced Technology Telescope and

12. Steady state of an ATP-driven calcium pump: limitations on kinetic and thermodynamic parameters.
A numerical analysis was carried out to explore limitations on kinetic and thermodynamic parameters for an ATP-driven Ca pump. A conventional pump reaction cycle was employed, with a transport stoichiometry of two Ca ions per cycle. Rigid requirements were imposed to represent the needs of physiological function, defined as the ability to maintain the cytopl
