objective : double aortic arch (daa) is a rare congenital malformation. strategies for diagnosis and treatment are different. thoracoscopic treatment of daa is limited to case reports or little case series. we report a description of our diagnostic and therapeutic approach and evaluate outcomes. methods: we reviewed charts of infants with double aortic arch who were hospitalized in our departme...

Groundwater recharge rate estimation is crucial to sustainable development of aquifers in intensely pumped regions, such as the Urucuia Aquifer System (UAS). A sedimentary aquifer Western Bahia, Brazil, that underlies one major agricultural areas country where there has been growth irrigated areas. This study seeks evaluate component water budget UAS area, based on three complementary technique...

Changes in land use the Air Dingin watershed (DAS) area Padang City, Indonesia, lead to a decrease rainwater infiltration volume ground. Some Latung sub-watershed capacity with an increase surface runoff. This research aims determine effect of land-use changes on and Purposive sampling method was used this research. The measured directly field using double-ring infiltrometer, data processed Hor...

Agricultural development with horticultural crops on dry land is one of the government's efforts to increase productivity so that new paddy fields are created in Bayan area. Noting infiltration capability and its classification important factors needed irrigation planning support agriculture, it necessary conduct field research this matter. This study aims determine characteristics trend can be...

Due to increasing demand for limited water resources, the pressure on irrigation used in agricultural production is also increasing. One of alternative solutions meet needed use low-quality resources. However, these waters can cause serious problems environment, especially soil and plants, short, medium long term. The sodium concentration affects structure soil, infiltration rate hydraulic cond...

Measuring infiltration and leaching at the plot scale is difficult, especially for high hydraulic conductivity soils. Infiltration rate has been indirectly calculated at the plot scale by comparing surface runoff to rainfall. Direct measurement of infiltration and leaching beyond the point scale is typically limited to locations where land forming has been performed, e.g. infiltration ponds and...

Prediction of soil characteristics over large areas is desirable for environmental modeling. In arid environments, soil characteristics often show strong ecological connectivity with natural vegetation, specifically biomass and/or canopy cover, suggesting that the soil characteristics may be predicted from vegetation data. The objective of this study was to predict soil infiltration characteris...
