1. Mechanical and morphological characterizations of carbon fiber fabric reinforced epoxy composites used in aeronautical field
Carbon fiber reinforced composites (CFRC) have been used in aeronautical industry in the manufacture of different aircraft components that must attend tight mechanical requirements. This paper shows a study involving mechanical (flexural, shear, tensile and compressive tests) and morphological characterizations of four different laminates based on 2 epoxy re

2. Construção de uma armadilha magneto-ótica para aplicações em informação quântica e física atômica / Construction of a Magnet-Optical Trap for Aplications at Quantum Information and Atomic Physics
We built a magneto-optical trap (MOT) for rubidium as a first step for the trapping of a cloud of cold atoms in a periodic potential formed by light beams. This system will be used for experiments in atom physics, with possible applications in quantum information. A MOT is necessary to avoid the problems imposed by the thermal agitation of the atoms to the m

3. On a gravitational cutoff for the vacuum energy
A possible connection between the energy W of the vacuum fluctuations of quantum fields and gravity in "empty space" is conjectured in this paper using a natural cutoff of high momenta with the help of the gravitational radius of the vacuum region considered. We found that below some "critical" length L = 1 mm the pressure sigma is one third of the energy de

4. Contributions to analysis, calculation and modeling of vacuum systems / Contribuições para analise, calculo e modelagem de sistemas de vacuo
O principal objetivo deste trabalho foi contribuir para o cálculo, análise e modelagem de sistemas de vácuo de uso geral. As contribuições ocorreram na criação, desenvolvimento e aprimoramento de ferramentas matemáticas tanto analíticas como numéricas para modelar e analisar detalhadamente sistemas de vácuo. Foram consideradas duas maneiras de mod

5. Desiccation Tolerance of Five Tropical Seedlings in Panama. Relationship to a Field Assessment of Drought Performance1
Studies of the desiccation tolerance of the seedlings of five tropical trees were made on potted plants growing in a greenhouse. Pots were watered to field capacity and then dehydrated for 3 to 9 weeks to reach various visual wilting stages, from slightly wilted to dead. Saturated root hydraulic conductance was measured with a high-pressure flowmeter, an

6. Ultrasensitive magnetic biosensor for homogeneous immunoassay
A technique is described for specific, sensitive, quantitative, and rapid detection of biological targets by using superparamagnetic nanoparticles and a “microscope” based on a high-transition temperature dc superconducting quantum interference device (SQUID). In this technique, a mylar film to which the targets have been bound is placed on the micr
