1. Family of polynomials: Rouh-Hurwitz and Kharitonov´s theorem / Familias de polinômios estáveis: teoremas de Routh-Hurwitz e Kharitonov
The objective of this work is to determine when all of zeros of a given polynomial have negative real parts, called stable or Hurwitz polynomials. We will present and prove the Routh-Hurwitz criterion. Furthermore we will extend the result for classes of polynomials defined by letting their coeficients vary independently in an arbitrary finite interval. Then

2. Dynamic modeling and stability analysis of a liquid rocket engine.
The stability of a liquid rocket engine (LRE) has long been extensively studied in foreign space programs, mainly because the combustion chamber, by itself, is a source of unstable process. The next phase of the Brazilian space program requires a reliable engine to fulfill the mission goal. Thus, understanding and predicting the influence of self-oscillating

3. Basis of guanylate cyclase activation by carbon monoxide.
Kinetics of CO association with guanylate cyclase [GTP pyrophosphate-lyase (cyclizing), EC 4.6.1.2] and dissociation from carboxy guanylate cyclase have been studied at pH 7.5 by flash photolysis, yielding rate constants at 23 degrees C of 1.2 +/- 0.1 x 10(5) M-1.sec-1 and 28 +/- 2 sec-1, respectively. While the CO combination rate constant is the same as fo

4. Peak expiratory nitric oxide differences in men and women: relation to the menstrual cycle.
OBJECTIVE--To develop a method to measure end expiratory nitric oxide concentration and to use it to determine whether there are sex related differences between healthy men and women. DESIGN--Modification of commercially available chemiluminescent analyser to allow endogenous nitric oxide (endothelium derived relaxing factor) to be measured in a single slow
