1. Processos dinÃmicos e evolutivos da zona costeira de Itamaracà por sensoriamento remoto e medidas in situ
The coastal zone of Itamaracà is like a highly dynamic environment where land and oceanic processes interact altering frequently coastal characteristics. In this context, this current study examines the responsible processes of such changes from the development and application of methodologies, which includes digital image processing and the obtaining of in

2. Evaluación de los efectos de la rotación en operadores de motosierras
An study was carried out in the natural forests of Pinus caribaea, Pinar del Rio province, Cuba, aiming at the evaluation of the different methods used for clearcuting with chainsaw, using the cut-to-length system conducted in such a way to diminish the risks of the occupational diseases in chainsaw operators, and simultaneously to maintain the productivity

3. Modelamento e analise de guias dieletricos planares atraves do metodo FDTD
In this work a finite-difference time-domain method formulation to the analysis of propagation characteristics in bidimensional dielectric planar structures (slab waveguide and directional coupler) is presented. A direct solution of Maxwell s equations is searched, replacing the partial derivative enc1osed in the differential operators by finite differences.

4. Modified nucleotides reveal the indirect role of the central base pairs in stabilizing the lac repressor-operator complex.
Guanine residues in the lac operator were replaced by 2-aminopurine or purine analogues, pairing the modified nucleotides with C. The observed equilibrium dissociation constants for lac repressor binding to substituted operators were measured in 10 mM Tris, 150 mM KCl, 0.1 mM EDTA, 0.1 mM DTE, pH 7.6 at 25 degrees C. These measurements revealed five position
