1. Estudo de conformação de cerâmicas à base de zircônia para aplicação em células a combustível do tipo óxido sólido / STUDY OF TAPE CASTING OF YTTRIA STABILIZED ZIRCONIA FOR APPLY IN SOLID OXIDE FUEL CELL
The hydrogen economy has been risen as new option for supply the growing global demand for energy. A fuel cell is an electrochemical device able to use hydrogen as a energy source. Carbon dioxide (CO2) emission is very low so it is ecologically friendly, once energy is produced by a reaction of hydrogen and oxygen. The production of energy from hydrogen fuel

2. Análise de conforto e elastocinemática das suspensões de duplo estágio de um veículo de competição off-road em ambiente multicorpos / Elastokinematic and ride analisys of a off-road competition vehicle double rate suspension using a multibody model
This dissertation presents the study of a off-road competition vehicle ride and the double rate suspensions elastokinematic behavior using the multibody software MSC-ADAMS. The vehicle multibody model includes the rear and front suspensions, the steering system, the tires and the sprung mass. The suspensions elastokinematic analysis defined geometric configu

3. Stimulation of 16-dehydroprogesterone and progesterone reductases of Eubacterium sp. strain 144 by hemin and hydrogen or pyruvate.
Suspensions of Eubacterium sp. strain 144, prepared from cells grown with 16-dehydroprogesterone, catalyzed the reduction of this steroid to 17-isoprogesterone at a very low rate. Modifications of the assay to optimize the pH (5.5) and increase the steroid solubility (10% [vol/vol] methanol) did not significantly enhance the reaction. However, growth of stra

4. Electrorotation of colloidal particles and cells depends on surface charge.
The importance of surface conductivity to the frequency-dependent polarizability and the rotation of particles in circular electric fields (electrorotation) is emphasized by various theoretical and experimental investigations. Although surface conductivity seems to be naturally related to the ionic double layer, there is rare experimental evidence of a direc

5. Fluorometric Determination of Deoxyribonucleic Acid in Bacteria with Ethidium Bromide
A simple, sensitive, and rapid method is presented for the determination of deoxyribonucleic acid (DNA) in both gram-positive and gram-negative bacteria. It is based upon the fluorometric determination of DNA with ethidium bromide after alkaline digestion of the bacteria to hydrolyze the interfering ribonucleic acid. The assay takes less than 2 hr. Its sensi
