25. Aspectos limnológicos e sanitários de uma lagoa costeira no litoral leste do Ceará - lagoa do Batoque / Limnological and sanitary aspects of a coastal lagoon in the eastern coast of Ceará lagoa do Batoque
The water quality of Batoque lagoon, a coastal lagoon located along the eastern shoreline of the state of Ceará, Brazil, was characterized by means of monthly samplings from May to November 2005 to obtain dry-season (May-Jun) and wet-season (Aug-Nov) data. Additionally, two nycthemeral (24hr.) samplings were performed in July and December to observe daily v

26. Interpretação de deformação e recalque na fase de montagem de estrutura de concreto com fundação em estaca cravada / Strain and settlement interpretation in the assembly of a concrete structure supported by driven piles
Although encouraged by several authors and by the Brazilian Foundation Code, reports of actual column loads measurement in natural scale are not frequent in our technical literature, especially in the case of buildings supported by deep foundations. Results of load and settlement measurements at 20 contiguous columns of a structure built in pre-cast reinforc

27. Avaliação de interferencias na pre-concentração on-line de arsenio utilizando silica gel modificada com oxido de zirconio / Evaluation of interferences for in on-line preconcentration of arsenic using silica gel modified with zirconium oxide
A técnica de geração de hidretos é seletiva, devido à separação das espécies de interesse da matriz na forma de hidretos antes da atomização. Entretanto no sistema de pré-concentração de arsênio estudado observou-se alguns efeitos de interferência devidos principalmente à presença dos ânions fosfato e sulfato, em função do material sorven

28. 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

29. ESTUDO EXPERIMENTAL SOBRE OS EFEITOS DA FLUÊNCIA DO CONCRETO EM PILARES ESBELTOS / EXPERIMENTAL STUDY ON THE EFFECTS OF THE CONCRETE CREEP IN SLENDER COLUMNS
Sustained loads cause a progressive increase of the strains in a structure due to concrete creep. In general, creep strains do not affect the strength of the structural elements. In slender columns, however, they can reduce the load capacity as a result of the continuous increase of the second order eccentricity, leading to the column instability. An experim

30. Methodological aspects to determining the internal loads on the human column. / Aspectos metodológicos para a determinação de cargas internas na coluna vertebral.
Load lifting yields a contact force in the lumbar region (L5-S1) that can sometimes reach the value of the body weight, depending upon the elevated load. Force analyses (muscular, weight, load), the spine being consided as a rigid shank, with extension beimg done only by the erector spine musculature, represent a poor approximation, since the several muscula

31. Biomechanical Stability of Four Fixation Constructs for Distal Radius Fractures
Implants available for distal radius fracture fixation include dorsal nonlocked plating (DNLP), volar locked plating (VLP), radial–ulnar dual-column locked plating (DCPs), and locked intramedullary fixation (IMN). This study examines the biomechanical properties of these four different fixation constructs. In 28 fresh-frozen radii, a wedge osteotomy was pe

32. Variation of trabecular microarchitectural parameters in cranial, caudal and mid-vertebral regions of the ovine L3 vertebra
The lumbar vertebrae are major load-bearing structures within the spinal column. The current understanding of the microstructure of these bodies and their full role in load-bearing is incomplete. There is a need to develop our understanding of these issues to improve fracture prediction in musculoskeletal diseases such as osteoporosis. The lumbar vertebrae c
