1. Upregulation of intercellular adhesion molecule-1 and vascular cell adhesion molecule-1 in renal tissue in severe dengue in humans: Effects on endothelial activation/dysfunction
Abstract INTRODUCTION: Dengue is an important mosquito-borne disease in tropical and subtropical regions. Adhesion molecules have not been systematically characterized in the renal tissue of patients with severe dengue (SD). The objective of this study was to detect viral antigens in samples from patients that evolved with SD, correlating with the expressi

2. Simulation model of discret events applied to the planning and operation of a toll plaza
AbstractThis work investigates the congestion and traffic flow in a tool plaza, and proposes a methodology for the classification of highway flows and its service levels based on a combination of the Highway Capacity Manual – HCM and Discrete Events Simulation fundaments. The proposed mesoscopic simulation is used to analyze service levels of different phy

3. Biologia reprodutiva de rainhas e machos de Tetragonisca angustula (Hymenoptera: Meliponini) / Reproductive biology of the queens and males of Tetragonisca angustula (Hymenoptera: Meliponini)
The stingless bees (Hymenoptera: Meliponini)present a haplodiploid sex determination system with complementary sex determination in a single locus. Such a system is a large genetic load for the group and thus the genetic diversity of male\ s aggregations near the nests is essential to minimize the chances of inbreeding. The interactions among the stingless b

4. Alternativas de tratamento da água de lastro em portos exportadores de minério de ferro. / Ballast water treatment alternatives in the iron ore ports exporting.
This thesis aims at making a technical and economic analysis of the ballast water treatment in Brazilian iron ore ports. Three distinct treatment alternatives were studied: (1) onshore ballast water treatment; (2) water desalination plant to ballast water treatment; (3) onboard ballast water treatment in shuttle tanker vessels operating in the mooring, where

6. Metodologia para implementação de controle supervisório modular local em controladores lógicos programáveis / Methodology for implementation of supervisory control local modular in programmable logic control
Currently, manufacturing automation has assumed an increasingly important role within the industry and the problems of automated control systems have become increasingly complex. Thus, the traditional use of empirical methods heavily base on the experience of the programmer can lead to inappropriate or ineffective solutions. In this case, the Supervisory Con

8. Integrating time series mining and fractals to discover patterns and extreme events in climate and remote sensing databases.
This thesis presents new methods based on fractal theory and data mining techniques to support agricultural monitoring in regional scale, specifically regions with sugar cane fields. This commodity greatly contributes to the Brazilian economy since it is a viable alternative to replace fossil fuels. Since climate influences the national agricultural producti

10. Desenvolvimento psicológico e transtorno de déficit de atenção e hiperatividade (TDAH): a construção do pensamento operatório / Psychological development and Attention Deficit Hyperactitity Disorder (ADHD): the construction of operational thinking
Attention Deficit Hyperactivity Disorder (ADHD) is one of the most prevalent disorders in childhood and adolescence. Recent research shows that, at least from a cognitive level, there are important differences in the development of children with ADHD when compared with children without any psychiatric diagnosis. This work aims to contribute to the field of r

12. O uso da simulação no suporte a implementação da estrutura de controle supervisório
Abstract: The growth of competitiveness in enterprises has forced them to reduce more the releasing time of their products. Consequently, the enterprise and academy s effort in providing techniques and tools for the reconfiguration of its systems is in force. A manufacturing system is a classical example of a Discrete-Event System (DES), for its dynamics dev
