25. Dois pesos, duas medidas : gerenciamento de identidades orientado a desafios adaptativos para contenção de Sybils. / TwoWeights and two measures: using adaptive puzzles in identity management for sybil contention
O ataque Sybil consiste na criação indiscriminada de identidades forjadas por um usuário malicioso (atacante). Uma abordagem promissora para mitigar esse ataque consiste em conceder novas identidades mediante a resolução de desafios computacionais. Apesar de suas potencialidades, as soluções baseadas em tal abordagem não distinguem solicitações de

26. InfluÃncia da desnutriÃÃo neonatal em parÃmetros imunes de ratos treinados e submetidos ao estresse de contenÃÃo
Objective: The neonatal malnutrition (NM) influence was analyzed in immune parameters of 36 Wistar young adults (60 days) male rats, trained or not and submitted to the contention stress (CS). Methods: In the nurtured groups (casein 17%) and malnourished (8%) they were appraised total leukocytes (hemocytometer) and differentiate (blood smears); hemoglobin (c

28. Numerical model of oil spill as an environmental management method in contingency plan, applied to São Sebastião channel (SP). / Modelagem numérica do comportamento de derrames de óleo como método de gestão ambiental, em planos de contingência, aplicada ao canal de São Sebastião (SP).
The application of numeric models for analysis of oil spill in the coastal environments becomes one of the most important ways to understand the behavior of the oil in this case of impact, giving subsides to the prediction of the displacement of the patches and allowing best efficiency in the control of the extension of the impact agent. These assumptions gi

30. Interação da matéria de vórtices com estruturas de defeitos : detecção das primeiras penetrações
This thesis results from a systematic study of the interactions between penetrated vortices and pinning centers carried out on structured superconductors films of YBCO, Nb and Pb. A regular array of pinning centers (antidots, ADs) was inserted in those samples by mechanical indentations (in YBCO and Nb films), and by a lithographic processes (Pb). The struct

31. Transactional memories : prototyping and simulation of hardware implementations and a characterization of the problem of contention management in software / Memorias transacionais : prototipagem e simulação de implementações em hardware e uma caracterização para o problema de gerenciamento de contenção em software
As parallel architectures become prevalent in the computer industry, more and more programmers are required to write parallel programs and are thus being exposed to the problems related to the use of traditional mechanisms for concurrency control. Transactional memory has been devised as a means for easing the burden of writing parallel Programs: the program

34. Avaliação da regeneração óssea, sob a influência do laser de baixa intensidade, na região da sutura palatina de ratos após expansão da maxila / Evaluation of osseous regeneration, using the low-power laserterapy in the midpalatal suture in rats after maxillary expansion
Rapid maxillary expansion is one of the therapy used in the practice orthodontic to the posterior crossbite correction. Relapsed after expansion treatment required a contention device to guarantee a success therapy. The neoformation suture and the maxilla have maintained in the new position for a period to get the stability. To accelerate the osseous regener

35. Waters from the past and the reservoirs of Guaraú, Engordador and Cabuçu: a study of Industrial Archaeology / As águas do passado e os reservatórios do Guaraú, Engordador e Cabuçu: um estudo de arqueologia industrial
For this thesis we used Industrial Archeology methodology to analyze the water supply system for the city of São Paulo in the early 20th century, a period during which population density was growing rapidly and what had been a small nucleus of students was clearly destined to become a major metropolis. The most obvious solution, using water from the Tietê

Introduction. The City of São Paulo has been adopting highly measures to enable it to face up to the problem of flooding, among them being the construction of Reservoirs for the Containment of Flood Waters, known as "piscinões". In the dry season, after the occasional rains, these reservoirs, especially their hydraulic machinery, serve as breeding places f
