1. ImplementaÃÃo e AplicaÃÃo do Modelo de Visco-dano para problemas geomecÃnicos
A great advance in development of constitutive models for better simulation of geomechanical materials behavior has been observed in the last decades. A continuous medium subjected to degradation of its mechanical properties has a differentiated constitutive answer; hence itâs required the adoption of models based in Mechanic of Continuous Damage formulated

2. Sanitary quality of soybean seeds harvested at different times of the day and harvest times / Qualidade fisiológica e sanitária de sementes de cultivares de soja colhidas em diferentes épocas e horários
The objective of this work was to evaluate the influence of the time of the day and harvest time on seed sanitary quality of soybean cultivars. Five different times of the day (8:00 and 10:00 am, and 12:00, 2:00 and 4:00 pm) and two harvest times (R8 and R8 + 15 days) in association with fourteen cultivars (Conquista, Vencedora, Sambaiba, Garantia,, UVF 16,

3. Fadiga no domínio do tempo e da freqüência para solicitações torcionais
Nowadays, In due to the big number of studies applied on structural fatigue damage in time domain and frequency domain, besides the increasing of velocity and decreasing of costs on computation area, It is most important the metal-mechanic industries have prevision tools of endurance for their products increasing value, more reliability with big decreasing o

4. Desenvolvimento de um "phantom" para treinamento de biopsia de mama guiada por ultra-som / Phantom for Breast Biopsy Training Guided by Ultrasound
The main aim of work was the construction and characterization of acoustics proprieties of a prototype of phantom for the training of the breast biopsy guided by ultrasound. An important property of this phantom is its capacity of being thermically rebuilt after punctuated during the training and/or suffered any mechanic damage. For this purpose, a recycling

5. Estudo teórico-experimental do comportamento de nós de pórtico de concreto armado submetidos a ações cíclicas / Theoretical and experimental study of reinforced concrete frame joints behavior under cyclic load
The present thesis studies the behavior of frame joints in reinforced concrete beam-column joints subjected to cyclic loads. The thesis is divided into two parts: an experimental study and a theoretical-based study. The experimental study is based on laboratory tests on five physical models of beam-column joints. The results of this experimental study permit

6. Alergias, infecções respiratorias precoces e outros danos pulmonares são fatores mais associados a pacientes com sindrome do lactente chiador, matriculados no ambulatorio de lactente chiador da pediatria da Universidade Estadual de Campinas, região sudeste do Brasil
The wheezing infant syndrome (WIS) is a frequent and high morbidity-associated condition. Its appropriate diagnostic and therapeutic approaches depend not only on the application of the current literature concepts, but also on the knowledge of specific epidemiological characteristics of the underlying population. This was a prospective and observational stud

7. An Inspection System to Identify Fatigue Damage on Steel-Bridge Structures
Crack formation and growth in steel bridge structural elements may be due to loading oscillations. The welded elements are liable to internal discontinuities along welded joints and sensible to stress variations. The evaluation of the remaining life of a bridge is needed to make cost-effective decisions regarding inspection, repair, rehabilitation, and repla
