2. Physical, Chemical, and Microbiological Properties of Soil under Different Plant Covers in the Seridó Desertification Region in the Brazilian Semiarid
ABSTRACT The Seridó Desertification Region is a result of inadequate management of the native Caatinga vegetation, which generated degraded areas with little or no capacity for plant production. The area has experienced a succession of different land uses, but little is known about the impact of these changes. The present study tested the hypothesis that th

4. Development and selection of super-sweet corn genotypes (sh2) through multivariate approaches
ABSTRACT The aim of the present study was to investigate relations among ten traits in super-sweet corn genotypes assessed by means of simple correlation, path and canonical variable analyses, as well as to investigate the relative importance of such traits to the super-sweet corn breeding program developed at Darcy Ribeiro Northern Fluminense State Universi

5. Analytical Solution for Optimal Low-Thrust Limited-Power Transfers Between Non-Coplanar Coaxial Orbits
ABSTRACT: In this paper, an analytical solution for time-fixed optimal low-thrust limited-power transfers (no rendezvous) between elliptic coaxial non-coplanar orbits in an inverse-square force field is presented. Two particular classes of maneuvers are related to such transfers: maneuvers with change in the inclination of the orbital plane and maneuvers wit

6. Soil-vegetation relationships and community structure in a "terra-firme"-white-sand vegetation gradient in Viruá National Park, northern Amazon, Brazil
ABSTRACT Viruá National Park encompasses a vast and complex system of hydromorphic sandy soils covered largely by the white sand vegetation ("Campinarana") ecosystem. The purpose of this study was to investigate a vegetation gradient of "terra-firme"-white sand vegetation at the Viruá National Park. Nine plots representing three physiognomic units were ins

7. Environmental Management, Strategic Practices and Praxis: A Study in Santa Catarina Industrial Companies
This article analyzed the correlation between strategic praxis related to environmental management in Santa Catarina industrial companies and their strategic practices. This quantitative study is based on the theoretical foundations of environmental management and strategy as practice. Praxis (environmental management) is understood as a cluster of three per

8. Dimorphism and allometry of Systaltocerus platyrhinus and Hypselotropis prasinata (Coleoptera: Anthribidae)
Males of sexually dimorphic anthribid species display structural modifications that suggest sexual selection. Polyphenism, which is expressed through morphological and behavioral novelties, is an important component of the evolutionary process of these beetles. In this study, we endeavored to ascertain the presence of variations in selected monomorphic trait

10. Análise das variáveis de entrada de uma rede neural usando teste de correlação e análise de correlação canônica / Analysis of input variables of an artificial neural network using bivariate correlation and canonical correlation
The monitoring of variables and diagnosis of sensor fault in nuclear power plants or processes industries is very important because an early diagnosis allows the correction of the fault and, like this, do not cause the production interruption, improving operators security and its not provoking economics losses. The objective of this work is, in the whole of

11. Caracterização de germoplasma de soja quanto aos teores de proteína, óleo e ácidos graxos / Characterization of soybean germplasm for protein, oil and fatty acids contents
Soybean is currently the most prominent crop in the Brazilian production of grains. Its main products include oil and meal, which have been used for the production of food and animal feed. The high protein contents represent the main attraction of soybean use in diet. Furthermore, soybean oil has also been used in the production of biodiesel. These industria

12. Caracterização de germoplasma de soja quanto aos teores de proteína, óleo e ácidos graxos / Characterization of soybean germplasm for protein, oil and fatty acids contents
A soja é atualmente a cultura de maior destaque na safra brasileira de grãos. Entre seus principais produtos estão o óleo e o farelo, os quais têm sido matéria-prima para a produção de alimentos e ração animal. O elevado teor de proteína representa o principal atrativo do uso da soja na alimentação. Além disso, o óleo de soja tem sido também
