Theory of pipe drainage assisted by mole drainage

, : Theory of pipe drainage assisted by mole drainage. Journal of Irrigation and Drainage Engineering 124(2): 102-107

This paper addresses the problem of draining a heavy soil of low hydraulic conductivity overlying an impermeable layer by means of a combined system of pipe and mole drains. The analysis uses the complex functions and the theory of images to develop formulas for pipe and mole drain discharges and for pipe drain spacing design. A flow pattern predicted on the basis of these formulas shows that boundary conditions are satisfied and the stream line distribution is logical.

The cross structure (SW-NE) of the Gulf of Suez is well documented through several studies on the rifting in the area, whereas less emphasis has been placed on the structural interpretation along the axial direction of the rift itself.

Experiments on 38 bovine foetuses, 3-6 months old are described. The technique involved perfusion of the whole fetus using a mechanical heart-lung. Blood perfusion medium was diluted 50% with a buffer solution and adjusted to pH 7.6, and the whole...

Adverse childhood experiences (ACE) are associated with mental illness and smoking in adulthood, but ACE has not been studied as a determinant of this comorbidity. This study was designed to examine effects of ACE on the expression of smoking beha...
