1. Characterization of arrowroot starch in different agronomic managements
ABSTRACT Arrowroot is a plant originated in Latin America that has aroused interest in the food industry due to its high starch content, with differentiated characteristics and high commercial value. However, information on the management of arrowroot are scarce, precluding its commercial competition with other similar species, being necessary further studie

2. DENDROECOLOGIA DE Cedrela fissilis (Vell.) NA REGIÃO DE SANTA MARIA, RS / DENDROECOLOGY OF Cedrela fissilis (Vell.) IN THE SANTA MARIA REGION OF RS
Cedrela fissilis (Vell.) is a species that has a considerable growth and a high quality wood, and because of that it is a potential species for native forests management. However, for the proper handling of this species is necessary the knowledge about its self-ecology and its dynamic in the forest. In order to contribute to the advancement of forest managem

3. Networks with spatio temporal dynamics in computer sciences / Redes com dinâmica espaço-temporal e aplicações computacionais
In the last decades, an increasing interest in complex system study has been witnessed. Such systems have at least two integrated fundamental components: individual dynamical elements and an organizational structure which defines the form of interaction among those elements. Due to the dynamics of each element and the coupling complexity, various spatial-tem

4. Support vector machines and particle swarm optimization applied to reliability prediction
Reliability is a critical metric for organizations since it directly influences their performance in face of the market competition, as well as is essential in maintaining their production systems available. The prediction of such quantitaive metric is then of great interest, as it may anticipate the knowledge about system failures and let organizations avoi

5. SOIL PHYSICAL AND BIOLOGICAL CHARACTERIZATION AFTER HERBICIDES APPLICATION IN BLACK WATTLE (Acacia mearnsii De Wild.) STANDS IN RIO GRANDE DO SUL / CARACTERIZAÇÃO FÍSICA E BIOLÓGICA DO SOLO APÓS APLICAÇÃO DE HERBICIDAS EM PLANTIOS DE ACÁCIA-NEGRA (Acacia mearnsii De Wild.) NO RIO GRANDE DO SUL
The study of soil quality biological indicators in areas classified as forest production units is important to understand the ecological processes that occur in these systems. Monitoring the soil fauna in modified environments, when management practices involve chemical products in the environment, is an instrument that allows to evaluate not only the soil q

6. Structural and dynamical properties of a quasi-onedimensional classical binary system / Estudo das propriedades estruturais e dinÃmicas de um sistema binÃrio quasi-unidimensional.
The aim of this work is to study the structural and dynamical properties of a classical binary system of charged particles confined in a two dimensional channel. Such a system is described in the literature as quasi-unidimensional, and its relevance is supported by the possibility of technological applications, shown recently in the scientific literature, an

7. Ladrilhos e revestimentos hidráulicos de alto desempenho / High performance hydraulic tiles and coverings
The hydraulic tiles are coverings produced by using hydraulic binders, whose production technology has not follow the great technological evolution of the concretes, the availabilities of new materials and the usual techniques in recent years, thus they have lost space and competition in the market due to their handicraft characteristic of production. This w

8. Dinamica não linear e interações de defeitos topologicos e solitons na presença de forças externas e impurezas
We study the catastrophes that can occur in kink dynamics in the presence of external forces and impurities. Under the action of some anharmonic forces it can occurs that not only the translational mode is unstable but also the internal modes ( shape modes) or even part of the continuum spectrum ( the soliton is unstable against the interaction with phonons!

9. Estrutura nuclear e competição entre modos de decaimento de ressonancia gigantes
The low-lying leveI structure of the odd-mass Pb isotopes ( 193A205) is investigated in terms of the projected BCS approximation (PBCS) with one- and three- quasiparticle. A surface delta interaction (SDI) is used as residual interaction. Excitation energies, spectroscopic factors magnetic dipole and electric quadrupole moments are calculated and compared wi

10. Estudo de anisotropia magnética nos compostos intermetálicos ErFe3Hx e (Er1-x Gdx)Fe3 por espectroscopia Mössbauer no 57Fe
The magnetic anisotropy in the ternary hydrides ErFe3Hx and in the pseudobinary (Eri _ x Gd x )Fe3 compounds has been studied by 57 Fe Mdssbauer spectroscopy. ErFe3 shows a spin reorientation from basal plane above 47 K to the C axis below this temperature. The direction of the magnetization is the result of a competition between the crystal field anisotropy

11. Dissociation of influenza virus hemagglutinin and neuraminidase eliminates their intravirionic antigenic competition.
When presented together on the intact influenza virus particle, the external hemagglutinin (HA) and neuraminidase (NA) antigens are competitive, with HA dominant over NA in both T- and B-cell priming (B. E. Johansson, T. M. Moran, and E. D. Kilbourne, Proc. Natl. Acad. Sci. USA 84:6869-6873, 1987). Dissociation and purification of HA and NA from virus and th

12. U1 small nuclear ribonucleoprotein particle-protein interactions are revealed in Saccharomyces cerevisiae by in vivo competition assays.
Two highly conserved regions of the 586-nucleotide yeast (Saccharomyces cerevisiae) U1 small nuclear RNA (snRNA) can be mutated or deleted with little or no effect on growth rate: the universally conserved loop II (corresponding to the metazoan A loop) and the yeast core region (X. Liao, L. Kretzner, B. Séraphin, and M. Rosbash, Genes Dev. 4:1766-1774, 1990
