1. Adjustment of nonlinear models and growth parameters and body nutrient deposition in meat-type and laying quail
ABSTRACT The objective of this study was to determine the adjustment quality of non-linear models and estimate the growth parameters and body chemical composition of a meat-type quail strain (Coturnix coturnix coturnix) and two laying quail strains (Coturnix coturnix japonica), designated yellow and red. The study used 1500 quail, not sexed, distributed in a

2. Cover Crops Effects on Soil Chemical Properties and Onion Yield
ABSTRACT Cover crops contribute to nutrient cycling and may improve soil chemical properties and, consequently, increase crop yield. The aim of this study was to evaluate cover crop residue decomposition and nutrient release, and the effects of these plants on soil chemical properties and on onion (Allium cepa L.) yield in a no-tillage system. The experiment

3. Desenvolvimento e produção de cana-de-açúcar em sistema sob palhada
Due to environmental constraints, lack of manpower and the search for better efficiency, the harvesting of sugar cane tends to be mechanized, causing large amount of straw is available in this new system. There are benefits to soil and culture provided by this residue. However, it was discussed what amount would be sufficient to promote these benefits and wh

4. Circuitos aritméticos e representação numérica por resíduos / Arithmetic circuits and residue number system
Este trabalho mostra os diversos sistemas de representação numérica, incluindo o sistema numérico normalmente utilizado em circuitos e alguns sistemas alternativos. Uma maior ênfase é dada ao sistema numérico por resíduos. Este último apresenta características muito interessantes para o desenvolvimento de circuitos aritméticos nos dias atuais, com

5. VIABILITY STUDY OF THE OPERATIONAL PROCESS OF CATURRITA CENTRAL RESIDUES TREATMANT PLANT (CTRC) SANTA MARIA, RS / VIABILIDADE DO PROCESSO OPERACIONAL DA CENTRAL DE TRATAMENTO DE RESÍDUOS DA CATURRITA (CTRC) SANTA MARIA, RS
This approach identifies some physical characteristics of the residues and the operational procedures converning the destination of these residues at the Central of Residues Treatment of Caturrita (CTRC), located on the city of Santa Maria (RS). The CTRC is composed by unit of selection, unit of compostage and sanitary embarement, wich supports a population

6. Hydraulic actuator failure prognostics.
This work presents an application of failure prognosis in the system command actuator of a commercial aircraft. An efficient failure prognostic algorithm provides a reduction in the number of unscheduled events and consequently generates a significant reduction in the maintenance costs. Although this is a simulation-based work, it presents a pre validation w

7. Geoprocessamento na escolha de sistemas ambientais para aterros sanitários na Região Metropolitana de Fortaleza CE. / GIS in the choice of environmental systems for landfills in the metropolitan area of Fortaleza - CE.
The great deal of rubbish production is, currently, one of the biggest worldwide problems and it tends to aggravate due to the high number of people in the globe and to the type of our productive system. Parallel to the solid residues increase, it also happens a reduction of available areas for its disposal and a raise of urban ground prices. It is what has

8. Germination and emergence of weeds in function of light and the sugarcane (Saccharum spp) harvest residue / Germinação e emergência de plantas daninhas em função da luz e da palha de cana-de-açúcar (Saccharum spp)
During the last years it has been observed an increase in the mechanical harvest without using fire of the sugar cane. This system has been modifying the characteristics of sugar cane, considering that leaves a straw harvest residue on the soil, which affects the light incidence on it and the occurrence and management of weeds. The present experiment was car

9. Modelagem e quantificaÃÃo da compactaÃÃo de latossolos cultivados com eucalipto / Pattern and quantification from compactation in the Latosols cultivated with eucalypt.
The harvest operations and wood transport involves intensive traffic of machines on the soil, which may traffic in a same line several times, or randomly. Besides the passes number, the wood load transported also may affect the soil compaction, when the applied pressures for the machines exceed its bearing support capacity, altering the place where the root

10. Resíduos de fenitrotion e esfenvalerato em grãos de milho e trigo, em alguns de seus produtos processados e sua ação residual sobre Sitophilus oryzae (L., 1763), Sitophilus zeamais Motsch.,1855 (Coleoptera: Curculionidae) e Rhyzopertha dominica (Fabr.,1792) (Coleoptera: Bostrichidae) / Fenitrothion and esfenvalerate residues in corn and wheat grain and in some of their processed products, and residual action on Sitophilus oryzae (L., 1763), Sitophilus zeamais Motsch., 1855 (Coleoptera: Curculionidae), and Rhyzopertha dominica (Fabr., 1792) (Coleoptera: Bostrichidae)
Because of the problems caused by insects in storehouses, chemicals have been chiefly used in Brazil to control these pests. However, success in solving problems with pests has been limited. In view of this, some aspects about stored grain protection were studied, among which are the following: 1) spray volume effect on grain moisture content, 2) stability o

11. Wavelet-packet identification of dynamic systems in frequency subbands.
This work presents a technique for linear system identification in frequency subbands by using wavelet packets. The wavelet-packet decomposition tree is used to establish frequency bands where subband models are created. An algorithm is proposed to adjust the tree structure, in order to achieve a compromise between accuracy and parsimony of the model. In a s

12. Productivity of maize âsafrinhaâ by direct planting system as a function of covering species and surface application of calcium / Produtividade do milho âsafrinhaâ em sistema plantio direto em funÃÃo da utilizaÃÃo de espÃcies de cobertura e aplicaÃÃo de calcÃrio em superfÃcie
The present work had for objective to evaluate the effect of different covering crops and the surface liming in no-tillage system, determining the content of dry biomass produced by each one of these species and the effect of the liming on the chemical properties of the soil and its consequent effect in the yield components and the productivity of the winter
