Descrição de dieta purificada para indução de quadro de desnutrição protéica em ratos
(Revista Brasileira de Medicina do Esporte, 1998-02-01) [Artigo]
No presente trabalho é descrita a composição de dieta hipoprotéica (6% de proteína) purificada para indução de quadro de desnutrição em roedores. A referida dieta foi padronizada em laboratório a partir de modificação da ...
Light and thermal excitation of depolarization current in indirect bandgap Alx Ga1-xAs
(Brazilian Journal of Physics, 1996-03-01) [Artigo]
Monochromatic light excitation in conjunction with thermally stimulated depolarization current measurements are applied to indirect bandgap AlxGa1-xAs. The obtained average activation energy for dipole relaxation is in ...
AVALIACAO DA REACAO DE MITSUDA EM PACIENTES VIRCHOVIANOS INATIVOS ANTES E APOS IMUNOTERAPIA
(Revista da Sociedade Brasileira de Medicina Tropical, 1995-01-01) [Artigo]
In this study the immunopotentiator levamisole as well as a mixture of BCG/Mycobacterium leprae were investigated in inactive lepromatous leprosy patients by using the Mitsuda reaction as a parameter. Twenty lepromatous ...
AN INVESTIGATION OF THE ELECTRONIC-STRUCTURE OF THE ANTITUMOR DRUG ELLIPTICINE AND ITS DERIVATIVES .1. GEOMETRICAL AM1 STUDY
(Theochem-Journal of Molecular Structure, 1992-01-31) [Artigo]
Ellipticine and its derivatives are a class of molecules that show antitumor and cytotoxic activity with a multimodal mechanism of action. In this paper we report a preliminary Austin Method One (AM1) study of ellipticine ...
Interaction potential between vortex lines for uniaxial superconductors in the London approximation
(Physical Review B: Condensed Matter and Materials Physics, 1996-06-01) [Artigo]
Two distinct expressions of the interaction potential between arbitrarily oriented curved vortex lines with respect to the crystal c axis are derived within the London approximation. One of these expressions is used to ...
Study of KCl + x% in and KCl + y% TlCl thin films
(Radiation Effects and Defects in Solids, 1998-12-01) [Artigo]
The present work reports the study of KCl thin films doped with In+ or Tl+. Both systems show optical absorption bands similar to single crystals. As the impurity concentration increases, so does the absorption as also the ...
MICHELS SYNDROME IN A BRAZILIAN GIRL BORN TO CONSANGUINEOUS PARENTS
(American Journal of Medical Genetics, 1995-07-03) [Artigo]
We report on a Brazilian girl born to consanguineous parents and presenting with craniosynostosis, telecanthus, blepharophimosis, blepharoptosis, epicanthus inversus, cleft lip and palate, skeletal defects, and hearing ...
Notas sobre ideologia e educação

Anelastic relaxation due to OH pairs in NbZr alloys
(Journal of Alloys and Compounds, 1994-09-01) [Artigo]
In the last 30 years several studies have been made to understand the relaxation mechanisms of the hydrogen atoms present in transition metals and their alloys. In this work, we observed the stress-induced ordering of ...
THE ENERGY BARRIER FOR ELECTRON TRAPPING IN ALXGA1-XAS
(Physica Status Solidi A: Applied Research, 1993-09-16) [Artigo]
Transient decay of persistent photoconductivity measurements are carried out in samples of different compositions. The capture barrier for electron trapping by DX centers is obtained using a method which employs the ...
