“Dewatering” of the lungs at birth [PDF]
Archives of Disease in Childhood - Fetal and Neonatal Edition, 1998 One of the most remarkable events to witness is the very rapid replacement of fluid by air in the normal neonatal lung at birth. Transformation to air breathing is so rapid that it is very difficult to envisage the normal physiological mechanisms for maintaining homeostasis in the air filled lung expelling so much fluid so rapidly—especially when, up ...

“Dewatering” of the lungs [PDF]
Archives of Disease in Childhood - Fetal and Neonatal Edition, 1999 Editor—The letter from Hills and Masters1in response to my commentary of their paper2 raises some interesting points which require further comment. I stand corrected over my description of their model of the alveolus as “dry.” This was a short hand term on my part to distinguish Hills’ theory on which he has published widely from the more traditional ...

Comprehensive experimental study on prevention of land subsidence caused by dewatering in deep foundation pit with hanging waterproof curtain [PDF]
Proceedings of the International Association of Hydrological Sciences, 2015 Land subsidence caused by dewatering of deep foundations pit has currently become the focus of prevention and control of land subsidence in Shanghai. Because of the reliance on deep foundation dewatering pit projects, two comprehensive test sites were

The Effect of Mine-Related Groundwater Use and Management on Surface Water in the Middle Humboldt River Basin. [PDF]
Ground WaterAbstract The Humboldt River, in Northern Nevada, USA, is a source of water for agricultural, municipal, and industrial uses. Mining has been active in Nevada since the 1800s. The recognition that groundwater withdrawal for many purposes—including mining—has the potential to deplete streamflow has prompted studies of the Humboldt River Basin.

Wall deflection induced by pre-excavation dewatering under different construction conditions
Yantu gongcheng xuebao, 2017 The existing field measurements show that the deformation of retaining wall and surrounding environment induced by pre-excavation dewatering can reach centimeter level, but the relevant researches are still less.

Analytical Analysis of Influence of Dewatering on Adjacent Pipelines Based on Pasternak Foundation
Shanghai Jiaotong Daxue xuebao, 2021 Based on the Pasternak model of elastic foundation beams, and combining the effective stress principle of soil and Dupuit hypothesis, the analytical solution of adjacent pipeline deformation in sandy soil caused by single well dewatering is derived.
