14. Métodos e ferramentas de interpolação para geração de mapas georreferenciados para tomada de decisão em irrigação de precisão / Interpolation tools and methods for georreferenced maps generation for decision making in precision irrigation
The agricultural quality and yield are highly related with the water readiness, because its privation can cause significant damages in critical periods. Due to that reason, irrigation becomes an important way of readiness water maintenance, with the goal of obtaining high level of agricultural quality and yield. The thematic maps have a very important role i

15. Avaliação do sensor de umidade TOPDEA no manejo da irrigação. / Evoluation of the moisture sensor topdea for irrigation scheduling.
The scientific community, in recent years, has intensified studies to measure the impacts to the environment caused by pollution, mainly the adverse effects to air and water. The fact that less than 1% of the global water resources is comprised of drinking water and available at the surface of the earth makes it a commodity of conflict. According to the FAO

16. Evapotranspiração da lima ácida Tahiti(Citrus latifolia Tan.) determinada por lisimetria de pesagem / Evapotranspiration of lime acid "Tahiti" (Citrus latifólia Tan.) determined by a weighing lysimeter
Brazil is the largest world producer of citrus crop, with São Paulo state leading as the largest national producer. Recent studies show that irrigated areas of citrus in the state have been increasing significantly in the last few years. However, lack of information on irrigation management related to this crop is one of the main problems encountered by the

18. VARIABILIDADE DA FITOMASSA DE FRUTOS DE ABOBRINHA ITALIANA E DE TOMATE E O PLANEJAMENTO EXPERIMENTAL / FITOMASS VARIABILITY OF FRUITS OF ZUCCHINI AND TOMATO AND THE EXPERIMENTAL PLANNING
To verify the variability interference of the estimates of the values used to determinate the plot size with simulations of different numbers of plants per plot and groupings of crops, a five-experiment work was carried out. One in the winter/spring of 2004, other in the summer/autumn of 2005 for the zucchini and three experiments with tomato in the winter/s

19. Avaliação ex vivo da precisão do localizador eletrônico Root ZX II na determinação da posição do limite CDC, utilizando-se o registro 1 do visor
It is generally accepted that root canal treatment procedures should be confined within the root canal system. To achieve this objective the canal terminus must be detected accurately during canal preparation and precise control of working length during the process must be maintained. Several techniques have been used for determining the apical canal terminu

20. Balanço hídrico e avaliação da chuva na cultura do cafeeiro / Water balance and rainfall evaluation in a coffee crop
The coffee plant has its growth and development strongly influenced by the water regime, either in favor or depressing the final yield, all depending on phonological stage. In order to have a better knowledge of the water requirement of the coffee crop, and also to have a more efficient irrigation management, a very useful tool is the water balance, which ca

24. Nutrition, growth, and growth modeling of eucalypt stands submitted to distinct water and nutrient availability / Nutrição, crescimento e sua modelagem em povoamentos de eucalipto em resposta à disponibilidade de água e nutrientes
The eucalypt culture in Brazil has a huge economical, environmental and social importance. In highly weathered soils of tropical regions, the maintenance of adequate flows of water and nutrients is fundamental to sustain yields and, therefore, the competitiveness of the forest sector in the international market. Evaluating and understanding how the water and
