The article describes the construction technology of closed horizontal drainage in irrigated areas, presents results theoretical studies to determine depth drainage, width trench, diameter pipe, thickness filter material, distance between drains and module. According studies, average is 1.5 m , trench 0.3 pipe 0.1 filtration material . 150 with module l/s 180 a drain 0.12 210 0.14

BACKGROUND Percutaneous nephrostolithotomy is important approach for kidney stones removal. A percutaneous nephrostomy drainage tube placement is an effective method to stop venous bleeding. Occasionally, the catheter can pierce into the renal parenchyma, and migrate into the renal vein even to the vena cava. CASE PRESENTATION A 66-year-old woman underwent a percutaneous nephrostolithotomy fo...

ABSTRACT-Nowadays farmers often use N-fertilizers to increase crop yield, but they lost quickly by leaching causes environmental contaminations that reported as most important source of pollutant. Although biofilters are useful for removing nitrate from drainage water, but many researches show that they need an external carbon source to sustain denitrification. Many researchers study on differe...

STUDY OBJECTIVE To assess the accuracy of chest ultrasonography in predicting pleural effusions > 500 mL in patients receiving mechanical ventilation. DESIGN Prospective study. SETTING Surgical and medical ICU in a teaching hospital. PATIENTS Forty-four patients receiving mechanical ventilation with indications of chest drainage of a nonloculated pleural effusion. INTERVENTIONS Diagnosi...

To optimize ecosystem services provided by agricultural drainage networks (ditches) in headwater catchments, we need to manage the spatial distribution of plant species living in these networks. Geomorphological variables have been shown to be important predictors of plant distribution in other ecosystems because they control the water regime, the sediment deposition rates and the sun exposure ...

OBJECTIVE To evaluate the influence of pleural drainage on the distance covered on the six-minute walk test, pain intensity and vital capacity in patients submitted to pulmonary resection. METHODS Thirteen consecutive patients from the Thoracic Surgery Infirmary of Hospital São Paulo, Brazil, submitted to closed pleural drainage (0.5-in multiperforated chest tube) in the postoperative period ...
