1. Hybrid motion planning approach for robot dexterous hands
This paper presents a manipulation planning approach for robot hands that enables the generation of finger trajectories. The planner is based on a hybrid approach that combines discrete-continuous kinematics using a fully discrete transition system. One of the main contributions of this work consists in the representation of the universe of different submode

2. Tensile and shear strength in the wood bonding surface, its impact on the finger geometry and on the mechanical properties of the finger joints / Resistência à tração da madeira e resistência ao cisalhamento no plano de cola, seus impactos na geometria do dente e propriedades mecânicas de emendas dentadas
A presente pesquisa teve como objetivo estudar a resistência ao cisalhamento no plano de cola de corpos de prova especiais e avaliar o seu impacto na geometria do dente, na resistência à tração de emendas dentadas e nas propriedades oriundas da flexão de vigas simples e compostas. A resistência ao cisalhamento no plano de cola foi estudada segundo o s

3. AVALIAÃÃO DO REVESTIMENTO A BASE DE LIGA DE NÃQUEL EM AÃO ESTRUTURAL, EMPREGANDO O METAL DE ADIÃÃO ERNiCrMo-3 ATRAVÃS DA SOLDAGEM MIG/MAG / EVALUATE OF NICKEL WELD OVERLAY IN STRUCTURAL STEEL, WITH EMPLOYMENT OF GMAW ERNiCrMo-3 ELECTRODE.
The use of nickel alloy cladding components could be more frequently in petroleum industry. The crescent naphthenic corrosion and high molecular weight of national petroleum contribute for needs of materials with more resistance to corrosion, to temperature and to pressure. At this way, how part of systematic study, this work pretends to define operational r

4. Visualização e analise do deslocamento imiscivel e instavel em meio poroso consolidado
The main objective of this study is to investigate, at laboratory scale, the influence of both displacement velocity and mobility ratio on the relative permeability and geometry of two phase immiscible flow, in a naturally consolidated porous medium, in the presence of conate water saturation. The displacement experiments were carried out in cylindrical core

5. Spectroscopic studies of wild-type and mutant "zinc finger" peptides: determinants of domain folding and structure.
The "zinc finger" model [Miller, J., McLachlan, A. D. & Klug, A. (1985) EMBO J. 4, 1609-1614; Brown, R. S., Sander, C. & Argos, P. (1985) FEBS Lett. 186, 271-274] makes both specific structural and specific functional predictions about zinc finger consensus sequences that can be tested with a combination of genetic, molecular biological, and biophysical tech

6. Architectural rules of the zinc-finger motif: comparative two-dimensional NMR studies of native and "aromatic-swap" domains define a "weakly polar switch".
The Zn-finger motif, encoding a globular minidomain with characteristic structure, provides a striking example of a sequence template for protein folding. Insight into architectural rules relating the amino acid sequence of a protein to its structure and stability may be obtained by comparative study of analogues. As our first step toward defining such rules

7. Stereochemical basis of DNA recognition by Zn fingers.
DNA-recognition rules for Zn fingers are discussed in terms of crystal structures. The rules can explain the DNA-binding characteristics of a number of Zn finger proteins for which there are no crystal structures. The rules have two parts: chemical rules, which list the possible pairings between the 4 DNA bases and the 20 amino acid residues, and stereochemi

8. The conformations of hirudin in solution: a study using nuclear magnetic resonance, distance geometry and restrained molecular dynamics
The solution conformations of the protein hirudin have been investigated by the combined use of distance geometry and restrained molecular dynamics calculations. The basis for the structure determination comprised 359 approximate interproton distance restraints and 10 φ backbone torsion angle restraints derived from n.m.r. measurements. It is shown that hir

9. A retroviral-like metal binding motif in an aminoacyl-tRNA synthetase is important for tRNA recognition.
The gag genes of retroviruses encode nucleocapsid proteins that package genomic RNA and are essential for viral infectivity. These RNA binding proteins have a Cys-Xaa2-Cys-Xaa4-His-Xaa4-Cys zinc binding motif that is distinct from the typical zinc-finger motif Cys-Xaa2-Cys-Xaa12-14-His-Xaa2-His that is found in some transcriptional activators. Escherichia co

10. Crystal Structure of the GTPase-activating Protein-related Domain from IQGAP1S⃞
IQGAP1 is a 190-kDa molecular scaffold containing several domains required for interaction with numerous proteins. One domain is homologous to Ras GTPase-activating protein (GAP) domains. However, instead of accelerating hydrolysis of bound GTP on Ras IQGAP1, using its GAP-related domain (GRD) binds to Cdc42 and Rac1 and stabilizes their GTP-bound states
