1. Shear Properties of Carbon Fiber/Phenolic Resin Composites Heat Treated at High Temperatures
ABSTRACT Carbon fiber/phenolic resin composites have long been used as ablative materials in rocketry. Ablation is a complex multiscale problem where radiative and convective heating leads to the pyrolysis of phenolic resin matrix, resulting in the formation of a porous insulation char as thermal protection. This study investigates the shear properties evolu

2. Root Canal Filling: Fracture Strength of Fiber-Reinforced Composite-Restored Roots and Finite Element Analysis
O objetivo deste estudo foi avaliar o efeito da técnica de obturação na resistência à fratura de raízes e analisar, por meio de análise de elementos finitos (AEF), a expansão do cimento endodôntico em duas diferentes técnicas de obturação. Trinta dentes humanos unirradiculares foram instrumentados com limas rotatórias, com um comprimento de trab

3. Electroretinography in dogs using a fiber electrode prototype
We compared two electroretinography (ERG) electrodes in dogs using ERG standards of the International Society for Clinical Electrophysiology of Vision (ISCEV). Ten healthy Yorkshire terrier dogs (mean age, 2.80 ± 1.42 years; 6 females) weighing 5.20 ± 1.56 kg were evaluated using an ERG system for veterinary use. Dark- and light-adapted ERG responses were

4. Estudo da distribuição de luz vermelha e infravermelha em sangue humano diluído para circulação extracorpórea / Study of red and infrared light distribution in diluted blood for cardiopulmonary bupass surgery
Low level laser therapy (LLLT) is a treatment used in several applications, including the reduction of inflammatory processes. It could be used to prevent the systemic inflammatory response syndrome (SIRS), which some patients develop after cardiopulmonary bypass (CPB) surgery applied to solve some heart diseases. The objectives of this study were to set an

5. Sobre a Fibra Especial de Ideais
Neste trabalho estudamos a Cohen-Macaulicidade e a Gorensteincidade da fibra especial de um ideal em um anel local (R,m) de Cohen-Macaulay com dimensão d. Também obtemos uma fórmula para a multiplicidade da fibra especial de um ideal m-primário I em termos da multiplicidade mista ed−1(m|I) e elementos superficiais. Como consequência dessa fómula,

6. Structure and Development of Neuronal Connections in Isogenic Organisms: Transient Gap Junctions between Growing Optic Axons and Lamina Neuroblasts*
We previously showed that the growth of each bundle of eight optic fibers from one ommatidium into the optic lamina of Daphnia occurs in such a way that one of the eight fibers precedes the others into the lamina. The growth cone of this lead fiber makes surface contact with undifferentiated neuroblasts near the midplane. This is followed by a glial-like wra

7. Surface Movements during the Growth of Single Explanted Neurons*
The processes of isolated rat sympathetic neurons growing in culture were marked with glass or carmine particles and observed with timelapse microphotography. Particles on the processes moved with the cell in relation to the dish and underwent continual small jerky movements. They did not, however, show any over-all distal motion and for long periods, during
