1. Improvement in light utilization and shoot growth in Hymenaea stigonocarpa under high CO 2 concentration attenuates simulated leaf herbivory effects
ABSTRACT This study evaluated the photochemical responses of photosystem II and growth of Hymenaea stigonocarpa under CO2-enriched conditions with exposure to simulated herbivory events. After herbivory simulation in two distinct parts of the stem of plants (apex and base), chlorophyll a fluorescence, chlorophyll index, growth, extrafloral nectary density, l

2. Daycent Simulation of Methane Emissions, Grain Yield, and Soil Organic Carbon in a Subtropical Paddy Rice System
ABSTRACT The DayCent ecosystem model, widely tested in upland agroecosystems, was recently updated to simulate waterlogged soils. We evaluated the new version in a paddy rice experiment in Southern Brazil. DayCent was used to simulate rice yield, soil organic carbon (SOC), and soil CH4 fluxes. Model calibration was conducted with a multiple-year dataset from

3. Tree Growth and Nutrient Dynamics in Pine Plantations in Southern Brazil
ABSTRACT For the development of nutrient budget models to recommend lime and fertilizers for agricultural and forestry crops, curves of plant growth and nutrient accumulation are required. Information about how nutrients are partitioned between the different plant organs is also necessary, but still scarce for pine in Brazil. This study evaluated the growth,

4. Integrated furfural and first generation bioethanol production: process simulation and techno-economic analysis
Abstract Furfural is a base chemical with a wide range of applications and with a great opportunity for market growth in the near term. Derived from biomass, its production may be incorporated to the Brazilian chemical industry using sugarcane bagasse as feedstock. In this context, the integration of a furfural plant to a first generation bioethanol facility

5. Calibration and validation of models for short-term decomposition and N mineralization of plant residues in the tropics
Insight of nutrient release patterns associated with the decomposition of plant residues is important for their effective use as a green manure in food production systems. Thus, this study aimed to evaluate the ability of the Century, APSIM and NDICEA simulation models for predicting the decomposition and N mineralization of crop residues in the tropical Atl

6. Simulação do crescimento da cana-de-açucar pelo modelo agrohidrológico SWAP/WOFOST / Sugarcane growth simulation by hydrological model SWAP/WOFOST
Modelos de simulação têm sido utilizados em estudos agronômicos e ecológicos como ferramenta de pesquisa, possibilitando organizar o entendimento das respostas das plantas a diferentes condições ambientais e, consequentemente predizer a produtividade das culturas. O sucesso na aplicação de modelos depende de sua calibração e das avaliações efetu

7. Simulation of growth and development of irrigated cowpea in Piauí State by CROPGRO model.
The objective of this work was to adapt the CROPGRO model, which is part of the DSSAT system, for simulating the cowpea (Vigna unguiculata) growth and development under soil and climate conditions of the Baixo Parnaíba region, Piauí State, Brazil. In the CROPGRO, only input parameters that define crop species, cultivars, and ecotype were changed in order t

8. Development and application of genétic model for QTL mapping in a full sib family / Desenvolvimento de modelo genético-estatístico para mapeamento de QTLs em progênie de irmãos completos, com aplicação em cana-de-açúcar
Sugarcane has great economic importance to Brazil, which is worlds largest producer. Currently, sugarcane receives worldwide attention due to the economic and environmental issues generated by its main product, ethanol. In this context, there is a scenario of potential growth for the culture, in which breeding can contribute to the development of new cultiva

9. Grain size evolution of a vanadium microalloyed steel during bar rolling mill - 38MnSiV5. / Estudo da evolução do tamanho de grão na laminação a quente de barras de aço médio carbono microligado ao vanádio - 38MnSiV5.
Microalloyed steels are used as forging stock for many automotive parts such as crankshafts and connecting rods. Using mathematical equations describing the recrystallization kinetics and grain growth, a spreadsheet has been developed to simulate the austenitic grain size evolution during bar rolling mill schedules as a function of temperature, strain rate a

10. O uso da simulação no suporte a implementação da estrutura de controle supervisório
Abstract: The growth of competitiveness in enterprises has forced them to reduce more the releasing time of their products. Consequently, the enterprise and academy s effort in providing techniques and tools for the reconfiguration of its systems is in force. A manufacturing system is a classical example of a Discrete-Event System (DES), for its dynamics dev

11. GRAPHIC SIMULATION OF CORN GROWTH / SIMULAÇÃO GRÁFICA DO CRESCIMENTO DE PLANTAS DE MILHO
The computer graphic simulation can be used to understand plant growth and development influenced by biotic or abiotic parameters. The main simulation purposes are: (i) to predict plant agronomic characteristics when its submitted to different climatic, environmental, and physical factors; (ii) to analyze the influence of these factors in plant growth and de

12. Rainfall retention in straw, plant and soil in corn and drybeans / Retenção de água da chuva na palha, solo e dossel vegetativo de milho e feijão
The water is the most important factor and, at the same time, the more limitant than the plant needs for its development. Short periods of hidric stress can reduce crop productivity. In this way, the importance of knowing the rainfall amount that is retained in plant, straw and soil is fundamental to calculating the exact amount of water requested by the pla
