1. Caracterização bioquímica e biofísica da Celobiohidrolase II do fungo Trichoderma harzianum IOC3844 produzida por expressão homóloga / Biochemical and biophysical characterization of cellobiohydrolase II from Trichoderma harzianum IOC 3844 produced by homologous expression
The depletion of reserves, especially of refined oil , with increased energy demands and the urgent need to reduce the carbon emissions on the atmosphere, signals the necessity to search for new sources of energy renewable and clean. Concerns about global warming have led to an increased world interest in biofuels. The new concept of second generation biofue

2. Triatomic molecules in two-dimensional layers
We found universal laws for the spectrum of two-dimensional three-body systems, composed by two identical particles and a distinct one (AAB). These universal laws appear when the potential range (r_0) is much smaller than the size of the system. In two dimensions this condition is formulated as (E2 is the two-body energy and ? is the reduced mass). The zero

3. EMPREGO DA PARAMETRIZAÇÃO DE HEISENBERG E DO MÉTODO DE ADOMIAN NO DECAIMENTO DA CAMADA LIMITE CONVECTIVA / EMPLOYMENT OF THE HEISENBERGS PARAMETERIZATION AND THE METHOD OF ADOMIAN IN THE DECAY CONVECTIVE BOUNDARY LAYER
No presente trabalho é apresentado um modelo espectral para descrever o decaimento da energia cinética turbulenta na Camada Limite Convectiva (CLC) da superfície terrestre, onde acontecem os processos físicos que geram turbulência de origem mecânica e convectiva no ar. Partindo das equações de conservação de momento, que descrevem a dinâmica de um

4. VARIAÇÕES ESPACIAIS DE PROPRIEDADES FÍSICAS DO REMANESCENTE DE SUPERNOVA RCW 103
Since the observation of the supernova event SN 1987A, observational research on supernova and supernova remnants, including the ones on the optical spectrum, has been much explored. However, most of these studies have been limited to present integrated or punctual data from extragalactic or galactic supernova remnants. The present work has the objective of

5. Thermodynamics properties of the Dirac oscillator and some contributions of the function theta of Jacobi / Propriedades termodinÃmicas do oscilador de Dirac e algumas contribuiÃÃes da funÃÃo theta de Jacobi
In this work we analyze the three-dimensional Dirac oscillator in a thermal bath. We found that the heat capacity is two times greather than the heat capacity of the one-dimensional Dirac oscillator in the higher temperatures. We begin with the energy spectrum of the three-dimensional Dirac oscillator, then we find the partition functions and others thermody

6. Modelo termodinamico para o aquecimento não-linear, a laser, e suas aplicações ao processamento de materiais
The subject of the computer modeling of the laser processing of materials continues to be highly topical in Materials Science. Basic to such an achievement was to have an well posed proposition to determine the time evolution of the temperature anywhere in the laser heated sample. Though models of such a kind abound in the literature, they are either rather

7. Spectral bifurcations in dispersive wave turbulence
Dispersive wave turbulence is studied numerically for a class of one-dimensional nonlinear wave equations. Both deterministic and random (white noise in time) forcings are studied. Four distinct stable spectra are observed—the direct and inverse cascades of weak turbulence (WT) theory, thermal equilibrium, and a fourth spectrum (MMT; Majda, McLaughlin, Tab
