43. Irrigation depths for wheat (Triticum aestivum L.) cultivars cropped in South region of Minas Gerais state / LÃminas de irrigaÃÃo para cultivares de trigo irrigado (Triticum aestivum L.) no Sul de Minas Gerais
The Brazilian wheat production in 2005 was 4,66 Mt, and the consumption was 10,21 Mt, which makes necessary for the country to import wheat (IBGE, 2006). The national average yield is 1975 kg/ha, and the state of Minas Gerais has an average yield of 3503 kg/ha. The state production was 23,54 thousand t, harvested in an area of 6,72 thousand ha (CONAB, 2006).

44. Study of the frequency response method applied on localization and quantification of leakage by pressure and discharge monitoring in water supply main pipes. / Estudo do método de resposta em freqüência para localizar e quantificar vazamentos através do monitoramento de pressões e vazões em adutoras de água tratada.
This work presents some methods for leak location, from de most elementary techniques and equipments, as visual inspection and mechanical geophone, until using sophisticated noise data-logger and computational modeling. Some of these techniques are very well issued and largely used by water companies, but others play excellent promises for the improvement of

45. DEVELOPMENT OF AN INTERFACE IN SIG FOR SUPPORT TO THE HYDRAULICAL SIZING OF SYSTEMS OF WATER SUPPLY / Desenvolvimento de uma Interface em SIG para Suporte ao Dimensionamento Hidráulico de Sistemas de Abastecimento de Água
The studies in water resources are models that need data gotten in the maps or research of field. Recently, these information are being added directly in Geographic Information System (GIS) due to the technological advances developed by these systems and to the continuous improvements in digital land model. Currently, efforts have been carried through to dev
