13. Moisture content evaluation of biomass using CFD approach
In grass conservation systems, drying in the field is an essential process upon which the quality and quantity of the material to be conserved is dependent on. In this study a Computational Fluid Dynamics (CFD) model, previously validated, was used to assess qualitatively and quantitatively the field drying process of cut grass under different weather condit

15. IPR 126 white oat forage potential under free growth, cutting and grazing at two management heights
The experiment was carried out to evaluate the structural characteristics, biomass accumulation, chemical composition and in vitro digestibility of dry matter and crude protein of white oat (Avena sativa L. IPR 126) under different management systems. Grazing, cut at two heights (15 and 20 cm) and free growth were all evaluated in three periods (July, August

16. A hybrid methodology to solve the container loading problem with weight distribution and cutting problems
Transport of goods has represented an important role in economic development throughout the history and ship containerization brought great advantages. Its invention in mid-1950s brought down the cost of transport and reduced time for loading and unloading cargo. Consequently, it increased efficiency of port working and reduced handling cargo to hours instea

17. SISTEMATIZAÇÃO DE CONHECIMENTO PARA O PROJETO DE PLATAFORMAS DE COLHEITA DE FEIJÃO / KNOWLEDGE SYSTEMATIZATION FOR THE DESIGN OF HARVEST HEADERS OF BEANS
Due to the need to increase in production and to the high rates of losses in the header because of machines with low efficiency in harvesting, it is presented, in this thesis the knowledge systematization needed to develop new header designs to harvest beans. This work presents the machines used for the harvest of beans, the harvesting systems, and a list of

18. Use of conditioners in the production of Tifton 85 grass hay
The objectives of this study were to estimate the curve of dehydration, bromatological composition and occurrence of fungi in Tifton 85 grass, submitted to four methods of dehydration. The curves of dehydration were studied in a completely randomized design with a 4 × 11 factorial scheme with four drying systems (1 conditioning + 1 turn-over; 2 conditioning

19. Production of tifton 85 hay overseeded with white oats or ryegrass
The objective of this experiment was to estimate the curve of dehydration, chemical composition and in vitro dry matter digestibility (IVDMD) and crude protein digestibility (IVCPD) of tifton 85 hay, produced single or overseeded with ryegrass or white oat IPR 126. The experimental design was in randomized blocks, in a 3 × 10 factorial arrangement, with thr

20. Sistema de produção de mudas de coqueiros híbrido e anão (Cocos nucifera L.) na região do Distrito Federal.
ABSTRACT: The coconut cultivated area has greatly increased in the Federal District Region of Brazil for the last five years. However, the crop management is still poor on seedling production. Therefore, the improvement of production methods has been highly demanded by coconut growers. Coconut seeds (fruits) should be collected from a superior genetic materi

22. Transcriptional networks reconstruction: identification of genes involved on cattle response to tick Rhipicephalus (Boophilus) microplus infestation.
In tropical countries, losses caused by tick infestation in cattle lead to a great impact on animal production systems. Weight and feed conversion reduction, together with diseases transmitted by the parasite are some of the problems that lead to economic losses of billion dollars a year. In a general way, Bos taurus indicus cattle are less susceptible to in

The integrated crop livestock farming system is an important training and renovation of degraded pastures. However, lack technical information about physiological and sanitary quality of the forage seeds and sowing methods have been suggested as causes of failure in some fields. This work aimed to evaluate the effects of treatment of seeds of Brachiaria briz
