1. Operational Performance of the Selective Cutting of Trees With Chainsaw
ABSTRACT The objective was to obtain a statistical model to estimate the operational performance of cutting trees with a chainsaw in the natural tropical forest north of Mato Grosso state. One-hundred-and-fifty-one operational cycles of selective logging for commercial purposes were registered. In each cycle, the effective time for cutting, the diameter of

2. ConstruÃÃo de cÃdigos de bloco lineares via transformadas digitais
New families of error-correcting codes, created from the Fourier number theoretic transform (Fourier Codes) and from trigonometric transforms over finite fields (FFCT-4e and FFST-4e Codes), are introduced in this dissertation. The code parity-check matrix, its dimension and minimum distance are obtained from the eigenstructure of the unitary Fourier number t

3. CLARITY AND OBSCURITY IN LEGAL TEXTS - A CASE STUDY: A COMPARATIVE LINGUISTIC ANALYSIS OF THE BRAZILIAN CIVIL CODE OF 2002 AND OF THAT OF 1916 / CLAREZA E OBSCURIDADE NO TEXTO LEGAL - UM ESTUDO DE CASO: ANÁLISE LINGÜÍSTICO-COMPARATIVA DO CÓDIGO CIVIL BRASILEIRO DE 2002 E DO DE 1916
This work focuses on the relation between language and Law, pointing out the distance that prevails between legal language and the language of the common man. By comparing segments of the Brazilian Civil Code of 1916 with those of the Civil Code of 2002, in regard to Successions Law, issues concerning syntactic structure, use of vocabulary and the presence o

4. INTERFACES ASSISTIDAS PARA DEFICIENTES VISUAIS UTILIZANDO DISPOSITIVOS REATIVOS E TRANSFORMADAS DE DISTÂNCIA / ASSISTIVE INTERFACES FOR THE VISUAL IMPAIRED USING FORCE FEEDBACK DEVICES AND DISTANCE TRANSFORMS
A evolução natural dos modelos de interface com o usuário ocorrida nas últimas décadas popularizou o padrão baseado em metáforas puramente visuais. Este processo impediu o acesso de deficientes visuais a computadores e a novas tecnologias. Algumas propostas foram feitas para reverter esta realidade. Entretanto, a maioria delas estava baseada em adapta

5. Structure of a bacterial photosynthetic membrane
The internal photosynthetic membranes of a photosynthetic bacterium, Rhodopseudomonas viridis, have been studied with a variety of electron microscope techniques. The membranes are composed of a sheet of apparently identical subunits arranged in a hexagonal fashion. The individual subunits repeat at a distance of 110 Å. Optical transforms have been used to

6. Further characterization and in situ localization of chain-like aggregates of the gliding bacteria Myxococcus fulvus and Myxococcus xanthus.
For the first time, chain-like aggregates, called "strands," have been enriched from crude cell wall preparations of liquid-grown vegetative cells of two strains of Myxococcus xanthus. These strands are highly isomorphic to macromolecular structures, previously described for Myxococcus fulvus (Lünsdorf and Reichenbach, J. Gen. Microbiol. 135:1633-1641, 1989

7. X-ray absorption fine structure as a monitor of zinc coordination sites during oogenesis of Xenopus laevis.
The x-ray absorption fine structure (XAFS) zinc K-edge steps for intact stages I,II and V,VI Xenopus laevis oocytes demonstrate that the zinc concentration is about 3 and 1 mM, respectively. However, the chi(k) function for the early stage oocytes differs markedly from that for the late one. Analysis of the XAFS data for stage I,II oocytes indicates that zin

8. Time-dependent diffusion in tubes with periodic partitions
The presence of obstacles leads to a slowdown of diffusion. We study the slowdown when diffusion occurs in a tube, and obstacles are periodically spaced identical partitions with circular apertures of arbitrary radius in their centers. The mean squared displacement of a particle diffusing in such a system at large times is given by ⟨Δx2(t)⟩=2Defft, t→
