2. Eficiência, custos e benefícios em contratos de parcerias público-privadas
Resumo: Este trabalho desenvolve um modelo teórico para compreender a elaboração do desenho de Parcerias Público Privadas. Toma-se como base o modelo de Iossa e Martimort (2012), modificando-o com a adição de um parâmetro que mede a sensibilidade dos esforços entre os estágios do projeto e também delimitando a variável que determina a flexibilidad

3. Mechanized methods for harvesting residual biomass from Mediterranean fruit tree cultivations
This study evaluates the technology and work systems used in order to harvest residual biomass from pruning in the specific conditions of Mediterranean fruit orchards (narrow distances between crop-rows). Harvesting has been divided into several types of operations - pruning, biomass alignment between crop tracks, biomass concentration in piles, chipping and

4. Determinantes da escolha de arranjos institucionais: evidências na Comercialização de Fertilizantes para Soja
As transações entre os agentes do agronegócio têm deixado de ocorrer estritamente via mercado, passando a serem regidas por diferentes tipos de arranjos institucionais, caracterizados por contratos. No setor de fertilizantes, as empresas intensificaram a oferta de pacotes de insumos aos produtores agrícolas, mais especificamente aos produtores de soja,

5. Estudo cristaloquímico de quatro derivados fenazínicos utilizando a difração de raios-X.
In general, natural and synthetic phenazines have attracted much attention because of their biological activities, like antitumour agents antimalarials, antibiotics, among others. The natural phenazines are isolated as secondary metabolites of terrestrial and marine microorganisms, mainly of Pseudomonas spp. and Streptomyces spp. This work aiming the structu

6. TELEFONIA MÓVEL: A PERCEPÇÃO DE VALOR NOS PACOTES DE SERVIÇOS / MOBILE TELECOMMUNICATIONS: VALUE PERCEPTIONS ON SERVICES BUNDLING
Esta pesquisa procura entender melhor de que forma as operadoras de telefonia móvel podem configurar suas ofertas de pacotes de produtos e serviços, através de um estudo de percepção de valor por parte dos clientes que já utilizam os serviços. Através de questionários estruturados, procurou-se avaliar a questão da percepção de valor dos usuários

7. Planejamento da rede de transmissão em telecomunicações : o problema do enfeixamento
Telecommunications has experimented high growth rates, causing a rapid development of new technologies. In the transmission area, the SDH technology (Synchronous Digital Hierarchy) replaces the PDH technology (Plesyochronous Digital Hierarchy), offering several improvements in management, channels add-dropping on the main stream and network security. The SDH

8. Um metodo heuristico de enfeixamento aplicado a rede de transmissão de grande porte
The emerging SDH transmission technology provides new opportunities to reshape Transport Networks, enabling telecommunications companies to support modern services required in todays competitive markets. However, this new technology requires a new planning methodology. One approach to satisfy this requirement is to divide the planning process in sucessi ve s

9. The bundling of actin with polyethylene glycol 8000 in the presence and absence of gelsolin.
Actin filament and bundle formation occur in the cytosol under conditions of very high total macromolecular concentration. In this study we have utilized the inert molecule polyethylene glycol 8000 (PEG) as a means of simulating crowded conditions in vitro. Column-purified Ca-actin was polymerized in the absence and presence of gelsolin (to regulate mean fil

10. Microtubule bundling by tau proteins in vivo: analysis of functional domains.
Tau varies both in the N-terminal region (three types) and in the C-terminal repeated microtubule binding domain (two types), generating six isoforms through alternative splicing. To understand the differences between the isoforms and to determine which domains are important for microtubule bundling, we performed transfection studies on fibroblasts using tau

11. Fascin, an echinoid actin-bundling protein, is a homolog of the Drosophila singed gene product.
A cDNA for fascin, an actin-bundling protein in echinoderms, has been cloned, sequenced, and expressed. The predicted mass of the protein is approximately 55 kDa, similar to that observed for fascin purified from sea urchin eggs. Bacterially expressed fascin reacts with antibodies prepared against sea urchin egg fascin. Fascin has a strong sequence similarit

12. A macroscopic scale model of bacterial flagellar bundling
Escherichia coli and other bacteria use rotating helical filaments to swim. Each cell typically has about four filaments, which bundle or disperse depending on the sense of motor rotation. To study the bundling process, we built a macroscopic scale model consisting of stepper motor-driven polymer helices in a tank filled with a high-viscosity silicone oil. T
