13. Non-invasive spectral detection of the beneficial effects of Bradyrhizobium spp. and plant growth-promoting rhizobacteria under different levels of nitrogen application on the biomass, nitrogen status, and yield of peanut cultivars
ABSTRACT High-throughput phenotyping using spectral reflectance measurements offers the potential to provide more information for making better-informed management decisions at the crop canopy level in real time. The aim of this study was to investigate the suitability of hyperspectral reflectance measurements of the crop canopy for the assessment of biomass

14. CALIBRATION AND TESTING OF CS-CROPGRO MODEL FOR COMMON BEANS
ABSTRACT: Simulation models of crop growth enable estimating crop yield and water balance components with low cost and high precision. This study aimed to calibrate and evaluate the performance of the CS-CROPGRO model for common beans under the conditions of Jaboticabal city (SP), Brazil. The model was calibrated and tested with data previously collected fro

16. Models of protein and amino acid requirements for cattle
Protein supply and requirements by ruminants have been studied for more than a century. These studies led to the accumulation of lots of scientific information about digestion and metabolism of protein by ruminants as well as the characterization of the dietary protein in order to maximize animal performance. During the 1980s and 1990s, when computers became

17. Growth Characteristics Modeling of Mixed Culture of Bifidobacterium bifidum and Lactobacillus acidophilus using Response Surface Methodology and Artificial Neural Network
Different culture conditions viz. additional carbon and nitrogen content, inoculum size and age, temperature and pH of the mixed culture of Bifidobacterium bifidum and Lactobacillus acidophilus were optimized using response surface methodology (RSM) and artificial neural network (ANN). Kinetic growth models were fitted for the cultivations using a Fractional

18. A crop model-based approach for sunflower yields
Pushed by the Brazilian biodiesel policy, sunflower (Helianthus annuus L.) production is becoming increasingly regarded as an option to boost farmers' income, particularly under semi-arid conditions. Biodiesel related opportunities increase the demand for decision-making information at different levels, which could be met by simulation models. This study aim

19. Individual tree growth models for eucalyptus in northern Brazil
The diameter and height growth model is one of three submodels used for simulating individual tree growth. In Brazil, there are few studies on the dimensional growth of individual trees be they native or exotic species, despite their potential. This study aimed to evaluate diameter and height growth models for individual trees for eucalyptus stands and to va

20. Growth characteristics modeling of Lactobacillus acidophilus using RSM and ANN
The culture conditions viz. additional carbon and nitrogen content, inoculum size, age, temperature and pH of Lactobacillus acidophilus were optimized using response surface methodology (RSM) and artificial neural network (ANN). Kinetic growth models were fitted to cultivations from a Box-Behnken Design (BBD) design experiments for different variables. This

21. Fine mapping and single nucleotide polymorphism effects estimation on pig chromosomes 1, 4, 7, 8, 17 and X
Fine mapping of quantitative trait loci (QTL) from previous linkage studies was performed on pig chromosomes 1, 4, 7, 8, 17, and X which were known to harbor QTL. Traits were divided into: growth performance, carcass, internal organs, cut yields, and meat quality. Fifty families were used of a F2 population produced by crossing local Brazilian Piau boars wit

22. Uma análise do emprego no setor da construção civil nos estados do nordeste brasileiro: qualidade do emprego formal e o retorno da educação
The Construction Industry has gained prominence on the national scene due to its ability to generate employment, and absorb much of the disqualified labor. On that perspective, this research aims to measure the quality of formal employment and quantify the impact of schooling on income of Construction Industry workers in the states of Northeast Brazil. In or

23. Comparação de diferentes formas de colheita florestal na Amazônia brasileira através da modelagem da produção e do crescimento / Comparison between different kinds of logging in the Brazilian Amazon by growth and yield models
A exploração madeireira na floresta Amazônica tem sido bastante discutida nos últimos anos. Novas técnicas de exploração que visam a redução do impacto proveniente da exploração têm sido criadas almejando o uso sustentável da floresta. Dessa forma, essa dissertação tem o objetivo de avaliar o período de recuperação da floresta tropical amaz

24. Application of the Hybrid-Maize model for limits to maize productivity analysis in a semiarid environment
Effects of meteorological variables on crop production can be evaluated using various models. We have evaluated the ability of the Hybrid-Maize model to simulate growth, development and grain yield of maize (Zea mays L.) cultivated on the Loess Plateau, China, and applied it to assess effects of meteorological variations on the performance of maize under rai
