6. Fabricação de microeletrodos para aplicações em microscopia eletroquímica de varredura / Fabrication of microelectrodes for applications in scanning electrochemical microscopy
In this study, platinum microelectrodes were fabricated with a Micropipette Puller and used in Scanning Electrochemical Microscopy (SECM) to obtain information on the acid erosion of tooth enamel. The sealing and polishing of the active area of the fabricated devices are considered critical steps in the construction process, hence a vacuum pump was used to e

7. Efeito de metodos de coleta de fluido ruminal em bovinos sobre alguns parametros ruminais e microbiologicos.
Estudou-se o efeito de tres metodos de coleta (manual, bomba e vacuo e sonda masoesofageana) sobre os teores de acidos graxos volateis totais (AGVt), nitrogenio amoniacal e numero de protozoarios no fluido ruminal de bovino. Utilizou-se o delineamento inteiramente casualizado, com tres tratamentos e cinco repeticoes. Os resultados revelaram que o metodo da s

8. Construção de um sistema simples e compacto de recirculação d'água sob pressão para trompa d'água
Vacuum pumps are very useful in physical, chemical and biological experiments. In this communication it is described the design of a compact and low cost water recirculating system employing a water-jet aspirator pump as the vacuum source. The system requires only a water pump, water-jet aspirator pump, commercial PVC water tubes and a drain connection.

10. Fabricação de multicamadas de Quantum Dots de PbTe por laser ablation
This thesis was dedicated to the fabrication of thin films, quantum dots and multilayer ofIV-VI semi conducting materiaIs by pulsed-Iaser deposition (PLD). In the first part we report on the construction of a "home made" facility for pulsed laser deposition. The basic experimental set-up fabricated for PLD consists of a vacuum chamber pumped to a base pressu

11. Compressão de ruido quantico e efeitos transversos em osciladores parametricos oticos
We present in this work the project and construction of an Optical Parametric Oscillator ( OPO ) , showing the quantum behavior in the intensity correlation of signal and idler beams, generated from a 532 nm pump. We have also studied, in a second set-up, the quantum noise compression in the pump beam reflected from an OPO cavity, obtaining 38% of noise redu

12. Otimização e comparação dos processos de desidratação osmotica a vacuo e a pressão ambiente de pseudofruto de caju (Anacardium occidentale L)
Despite being considered as an important producer of tropical fruits, Brazil presents a food wastage rate exceeding 35% of its production. This fact justifies research into low cost preservation methods leading to stable products and conserving, with only slight alterations, the nutritive and organoleptic characterisitics, aiming possibly at exportation. The
