13. EVOLUÇÃO DE UNIÃO DE BOLAS A PARTIR DO EIXO MEDIAL / EVOLUTION OF UNION OF BALLS FROM ITS MEDIAL AXIS
The computational study of unions of balls has applications in several domains of the Mathematics. The purpose of this dissertation is to propose a simplification of the union of balls in R2 through a movement that obeys the direction of the medial axis in order to simplify it, maintaining the major geometric elements of its shape. The disconnection of the s

14. Reconstrução de superfícies a partir de nuvens de pontos / Surface Reconstruction from Unorganized Points
Representações computacionais de formas podem ser criadas em ferramentas CAD ou geradas a partir de um objeto físico já existente. Esta última abordagem oferece como vantagens rapidez e fidelidade ao objeto original, que são os aspectos fundamentais em muitas aplicações, como Simulações Numéricas de Equações Diferenciais Parciais e Imagens Médi

15. A espermiogenese em Boophilus microplus (Canestrini, 1887) (Acari:ixodidae) : aspectos estruturais e ultra-estruturais
The objective of this study was to describe the spermatogenesis of the cattle tick (Boophilus microplus) (Canestrini, 1887), based on histological, histochemical, morphologic and ultrastructural infromation. Spermatogenesis occurs in the testis of ticks which begin their blood repast. The gametic cell lineage is isolated in cysts. Spermiogenesis begins in th

16. Postoperative Lateral Ligamentous Laxity Diminishes with Time After TKA in the Varus Knee
For successful TKA, good soft tissue balance is one of the most important factors; however, it is unknown whether the coronal balance immediately after surgery is maintained with time. We hypothesized, if neutral mechanical alignment was achieved at the time of TKA, some degree of lateral ligamentous laxity could be accepted and the laxity would diminish wit

17. Results in 50 cases of strabismus after graduated surgery designed by A scan ultrasonography.
Of 50 cases of strabismus having surgical operations designed on the basis of A scan ultrasonography 45 (90%) had less than 10 dioptres eso- or exodeviation two months postoperatively; 22 eso-, 25 exo-, and 3 vertical deviations were included in the series. A scan ultrasonography is done preoperatively to find the diameter and thus the circumference of the g

18. Novel Measurement Technique of the Tibial Slope on Conventional MRI
The posterior inclination of the tibial plateau, which is referred to as posterior tibial slope, is determined routinely on lateral radiographs. However, radiographically, it is not always possible to reliably recognize the lateral plateau, making a separate assessment of the medial and lateral plateaus difficult. We propose a technique to measure the platea

19. Assessment of left atrial dimensions by cross sectional echocardiography in patients with mitral valve disease.
Left atrial dimensions were measured using cross sectional echocardiography in 37 patients with mitral valve disease and 30 normal subjects of similar ages. The anteroposterior (AP), superior-inferior (SI), and medial-lateral (ML) left atrial dimensions were determined at the end of ventricular systole using parasternal long and short axis and apical four ch

20. Alterations in the Thickness of Motor Cortical Subregions After Motor-Skill Learning and Exercise
Behavioral manipulations such as housing in an enriched environment have been shown to increase brain weight and visual cortical thickness. The present study was designed to test whether skill learning or repetitive movements can alter the thickness of the motor cortex. One group of 6-mo-old Long-Evans female rats learned motor skills on an obstacle course t

21. The Dominant Mutant Wavy auricle in blade1 Disrupts Patterning in a Lateral Domain of the Maize Leaf1
Mature maize leaves have defined cell types along the proximal distal and medial lateral axes. The patterning events that establish these axes take place early in leaf initiation. We have identified a new dominant mutation, Wavy auricle in blade1 (Wab1), which affects patterning in both axes in a dose-dependent manner. Wab1 leaves are narrower than normal le

22. EphA3 Null Mutants Do Not Demonstrate Motor Axon Guidance Defects
Motor axon projections are topographically ordered. Medial motor column axons project to axial muscles, whereas lateral motor column axons project to limb muscles and, along the rostrocaudal axis of the animal, the more rostral motor neuron pools project to more rostral muscle targets. We have shown that EphA3 is specifically expressed in the developing medi

23. In vivo intramuscular fascicle-aponeuroses dynamics of the human medial gastrocnemius during plantarflexion and dorsiflexion of the foot
Velocity-encoded phase-contrast magnetic resonance (MR) imaging techniques and a computer-controlled MR-compatible foot pedal device were used to investigate the medial gastrocnemius muscle and aponeurosis deformations during passive and active eccentric movements of the plantarflexors. Intrafascicular strain, measured as the ratio of strain in the fascicle

24. The vomeronasal organ of the rat.
The anatomical organization of the vomeronasal complex of the rat (vomeronasal organ blood vessels, cartilage and glands) and the structure of the vomeronasal organ were studied. This organ is a tubular formation that shows different characteristics along its longitudinal axis. In its rostral portion it has a lateral flattened shape but caudally the organ ac
