1. Sobre H-hipersuperfÃcies compactas de N X R / H-hypersurfaces of N x R
Consideraremos F(N x R) o conjunto das H-hipersuperfÃcies fechadas M tal que M С N x R, onde N Ã uma variedade riemanniana simplesmente conexa com curvatura seccional limitada superiormente (KN ≤ -k2 <0). A partir daÃ, com o auxÃlio do Teorema de ComparaÃÃo do Hessiano mostraremos algumas desigualdades para estas subvariedades M С N x

2. Processos litográficos em filmes epitaxiais de compostos IV-VI para medidas Hall e o estudo da dopagem do telureto de chumbo com flureto de bário / Lithographic processes in epitaxial films of IV-VI compounds for Hall measurements and the study of lead telluride doping with barium flouride
The first part of the work dealt with the application of lithographical techniques to fabricate Hall geometry of IV-VI films grown on (111) BaF_2 substrates. A previous study of In diffusion in PbTe films confirmed the viability of using In as a metallic contact. During the lithographic process, some solutions were implemented to resolve the problems generat

3. Specific collapse followed by slow hydrogen-bond formation of β-sheet in the folding of single-chain monellin
Characterization of the conformational landscapes for proteins with different secondary structures is important in elucidating the mechanism of protein folding. The folding trajectory of single-chain monellin composed of a five-stranded β-sheet and a helix was investigated by using a pH-jump from the alkaline unfolded to native state. The kinetic changes in

4. Structure of the inhibitory region of troponin by site directed spin labeling electron paramagnetic resonance
Site-directed spin labeling EPR (SDSL-EPR) was used to determine the structure of the inhibitory region of TnI in the intact cardiac troponin ternary complex. Maeda and collaborators have modeled the inhibitory region of TnI (skeletal 96–112: the structural motif that communicates the Ca2+ signal to actin) as a kinked α-helix [Vassylyev, D., Takeda, S., W
