1. MÃtodo para avaliaÃÃo de aspectos de camada fÃsica e MAC de redes 802.11. / Method to evaluate physical and MAC layer aspects of 802.11 networks.
The present dissertation proposes a 802.11 network evaluation sequence which can be adopted, independently of the equipment used at the network. The log-distance path loss model is used for the environment characterization (by the model β parameter) where the network is evaluated. The specific objectives of each evaluation stage are presented and contex

2. Metodologia para planejamento da colheita e transporte florestal utilizando geotecnologia e pesquisa operacional / Methodology for planning forest harvesting and transport using geotechnology and operations research.
Considering the current scenario in which the use of forest resources is growing quickly, it is necessary the use of techniques and tools to facilitate the short, medium and long run planning, thus facilitating the search for a more rational use of these precious resources, assisting and supporting the decision making. This study aimed to use the geographic

3. A logÃstica internacional como diferencial competitivo para as empresas envolvidas nas importaÃÃes e exportaÃÃes brasileiras
This study intends precisely to incite the discussion on a model of administration of transport of loads and being safe in the movement and distribution of materials in the chain of international provisioning. It approaches the main themes focusing to the reverse of that chain, highly competitive nowadays and demanding in terms of reduction of costs, improve

4. The logistic of agricultural transport multimodal of the West Region from Paranà / A logÃstica de transporte agrÃcola multimodal da RegiÃo Oeste paranaense
Este trabalho de pesquisa compara as opÃÃes de monomodalidade, intermodalidade e multimodalidade para o transporte de granÃis agrÃcolas da regiÃo Oeste do ParanÃ. O propÃsito foi identificar as razÃes da pouca utilizaÃÃo da hidrovia em comparaÃÃo à rodovia e ferrovia, nessa regiÃo. Para isso, foram levantadas as principais caracterÃsticas dos

5. Análise técnica e econômica de um sistema de colheita florestal / Technical and economic analysis of a forest harvest system
Hand logging systems were the first adopted, mostly, in the exploitation of native forests, with no concern with the rationalization and productivity of such activities. In Brazil, the first activities of forest harvesting were carried out along the coast, at that time of discovery, when the main traded species was brazilwood. Machine selection and developme

6. Relação entre empresas florestais e comunidades do entorno: proposta para superação de conflitos / Relations between forest companies and communities of around: proposal for overcoming of social conflicts
The work discuss social demands presents in the brazilian forestry, which posses a land concentrative model. The focus is on the irregular withdrawal of wood the forest plantings for the communities of around, that they demand for work and job. The methodology was based in the participant observation of the research action and in exploratory research. As wor

7. Subsidies towards the management of the northern coast of São Paulo State: a case study of the larval settlement success of coastal decapods. / Subsídios para o zoneamento marinho do litoral norte do Estado de São Paulo: um estudo do sucesso do assentamento lerval de decápodos costeiros
O presente estudo foi realizado ao longo de uma linha de costa, incluindo duas enseadas em Ubatuba-SP, Brasil. Os objetivos principais foram: (1) Examinar, em seis costões rochosos, séries temporais de assentamento larval de decápodos, afim de entender forçantes físicas associadas ao transporte em direção à costa, (2) Localizar agregações larvais n

8. Diagnosis of the forest crop and wood transportation in fomented rural properties in the State of Espírito Santo / Diagnóstico da colheita e transporte florestal em propriedades rurais fomentadas no Estado do Espírito Santo
This study was developed with information obtained from interviews with 71 farm owners fomented by Aracruz Celulose, in the State of Espírito Santo. The main objective of this study was to diagnose the forest crop and wood transportation in their farms, considering technical, economic, social and environmental aspects. Those farm owners were responsible for

9. Reliability methodology for radial tires analysis in highway transport fleets. / Metodologia para análise de confiabilidade de pneus radiais em frotas de caminhões de longa distância.
A análise de pneus em frotas de caminhões de longa distância atualmente é realizada apenas para efeito de controle de estoque e determinação de causas de falhas. A metodologia de análise de confiabilidade apresentada neste trabalho, utilizando dados obtidos de pneus sucatados, sistematiza a mensuração e análise de perda de vida útil causada por ca

10. Magnesium Transport in Bacillus subtilis W23 During Growth and Sporulation
The active transport of magnesium by cells of Bacillus subtilis strain W23 occurs by a highly specific transport system (Mg2+ is favored over Mn2+, Co2+, or Ca2+) that is energy dependent (i.e., glucose is required in minimal medium and the system is inhibited by cyanide and m-chlorophenyl carbonylcyanidehydrazone). The rate of magnesium uptake by log-phase

11. Two Components of Auxin Transport 1
The transport of indoleacetic acid-1-14C out of sunflower stem sections has been analyzed by a compartmental analysis procedure in which the radioactivity moving out of the tissue (log per cent) is plotted against time. The analysis indicates that indoleacetic acid is transported via a fast transport system (t½ of about 30 minutes) and a slow transport syst

12. Bacterial Calcium Transport: Energy-Dependent Calcium Uptake by Membrane Vesicles from Bacillus megaterium
Membrane vesicles capable of energy-dependent calcium uptake have been prepared from Bacillus megaterium cells in log-phase growth or when undergoing sporulation. The uptake is dependent on the calcium concentration and appears saturable in vesicles from cells in log-phase growth. Both ascorbate and phenazine methosulfate are needed as a source of electrons
