2. Community ecology of parasites in four species of Corydoras (Callichthyidae), ornamental fish endemic to the eastern Amazon (Brazil)
Abstract Abstract: This study compared the parasites community in Corydoras ephippifer, Corydoras melanistius, Corydoras amapaensis and Corydoras spilurus from tributaries from the Amapari River in State of Amapá (Brazil). A total of 151 fish of these four ornamental species were examined, of which 66.2% were parasitized by one or more species, and a total

3. Carbon losses and soil property changes in ferralic Nitisols from Cuba under different coverages
ABSTRACT The transformation of primary forestlands into lands under cultivation exerts an impact on the physical and chemical properties of the soils, leading to loss of carbon from the soil. The aims of this study were (1) to estimate the impact of different land use on organic carbon stock (OC-stock) and (2) to determine the clay percentage, the dispersion

4. Assessing biomass based on canopy height profiles using airborne laser scanning data in eucalypt plantations
This study aimed to map the stem biomass of an even-aged eucalyptus plantation in southeastern Brazil based on canopy height profile (CHPs) statistics using wall-to-wall discrete return airborne laser scanning (ALS), and compare the results with alternative maps generated by ordinary kriging interpolation from field-derived measurements. The assessment of st

5. Litter production and seed rain in semideciduous forest fragments at different successional stages in the western part of the state of Paraná, Brazil
We documented litter production and seed rain in fragments of semideciduous forest (SDF) in the western part of the state of Paraná, Brazil: a late successional fragment (LF); an early successional fragment (EF); and a reforested late successional fragment (RLF). In each fragment, we established three permanent plots with four litter traps each, correspondi

6. Study of aluminum nitride precipitation in Fe- 3%Si steel
For good performance of electrical steels it is necessary a high magnetic induction and a low power loss when submitted to cyclic magnetization. A fine dispersion of precipitates is a key requirement in the manufacturing process of Fe- 3%Si grain oriented electrical steel. In the production of high permeability grain oriented steel precipitate particles of c

7. ESTUDO DOS SISTEMAS CeO2(1-x) :Pr6O11(x); CeO2(1-x):Fe2O3(x) E CeO2(0,95-x): Pr6O11(0,05):Fe2O3(x) PARA APLICAÇÃO COMO PIGMENTOS INORGÂNICOS DE BAIXA TOXICIDADE
This study focused on the Cerium oxide (CeO2) based pigmenting systems, doped with Praseodymium oxide (Pr6O11) and hematite (Fe2O3 iron oxide) synthesized through the solid state reaction (OM oxide mixture) and the Pechini method. Simultaneously, CeO2-Pr6O11-Fe2O3 ternary system pigments were synthesized through OM, with the addition of mineralizers. The sam

8. Chemistry and tensile properties of a recycled AA7050 via spray forming and ECAP/E
The aim of this work is to evaluate the conjugation of advanced processing techniques, such as spray forming, extrusion and ECAP as a processing route for reuse of machining chips generated during aircrafts manufacturing parts from AA7050-T7451 raw material plates supplied according to AMS 4050H¹. In this way, the sprayforming process was used for remelting

9. Biogeography on the early distribution of cuckoos (Aves: Cuculiformes)
Cuckoos are widely distributed, but are concentrated in the tropics, where they occupy a wide range of habitats. Both terrestrial and arboreal behaviors can be found in this group, but there is no consensus on as to whether these behaviors have arisen more than once. Moreover, the historical distribution of cuckoos is poorly understood. This paper presents a

10. Comportamento hidrodinâmico e cinético dos reatores anaeróbios compartimentado (RAC) e manta de lodo (UASB) operados em série / The hydrodynamic and kinetic bahavior of the anaerobic baffled reactor (ABR) and upflow anaerobic Sludge blanket (UASB) operated in serie
The aim of this research was to determine the hidrodymanic and kinetics behavior of a pilot system plant, treating swine liquid effluent, installed in the Zootechnical Department of the Federal University of Lavras. The pilot system was composed by several units working in series, such as sand retention box (SRB), static sieve (SS), acidification and equaliz

11. Proposta metodológica para elaboração de mapas de ruído em ambiente SIG, segundo norma ISO 9613-2
Noise mapping is a new activity with growing awareness among public officials and communities. This work presents a methodological proposal for the generation of noise maps in a Geographic Information System (GIS), based on ISO 9613-2, which standards the calculus for noise attenuation during propagation outdoors. Besides the definitions of methodological pr

12. Effects of changes in land use of the Brazilian Amazon on the ecological services provided by EscarabeÃneos (Coleoptera, Scarabaeidae). / Efeitos da alteraÃÃo do uso do solo na Amazonia Brasileira sobre serviÃos ecolÃgicos proporcionados pelos Scarabaeinae (Coleoptera, Scarabaeidae)
Ecosystem services provided by the biodiversity are that ones associated to live organism and that, in last analysis, affect natural process of human interest. Scarabeine dung beetles has been in evidence in the last years in function of the array of services provided, both in natural as in agricultural landscapes. This work aimed to evaluate the effect of l
