We report foam coarsening studies which were performed in the International Space Station (ISS) to suppress drainage due gravity. Foams and bubbly liquids with controlled liquid fractions φ between...
l and drainage has been central to the development of North America since colonial times, with the first organized drainage efforts occurring as early as the 1600s (Evans et al. 1996). Drainage has been encouraged to improve public highways, reduce public health risks, promote increased crop yield and reduced yield variability, reduce surface runoff and erosion, and increase land value. Agricul...
The effectiveness of Acid-Base Accounting (ABA) for predicting surface coal mine drainage quality in Pennsylvania was evaluated. Comparisons between ABA and mine drainage alkalinity, acidity, and sulfate were made for 38 mines in the bituminous coalfield. Neutralization Potential (NP), Maximum Potential Acidity (MPA), and Net Neutralization Potential (NNP) were evaluated with and without "thres...
OBJECTIVES Gait abnormalities are an early clinical symptom in normal pressure hydrocephalus (NPH), and subjective improvement in gait after temporary removal of CSF is often used to decide to perform shunt surgery. We investigated objective measures to compare gait before and after CSF drainage and shunt surgery. DESIGN Twenty patients and nine controls were studied. Quantitative gait measur...
BACKGROUND To evaluate the effect of no drainage in patients who underwent thyroidectomy and neck lymph node dissection. METHODS We followed the methodological standard expected by Cochrane. We searched the following databases by March 23, 2017: PubMed, The Cochrane Library, EMBASE via Ovid SP, and Medline via Ovid SP. Two reviewers screened the studies and extracted the data.

BACKGROUND Surgery in patients with obstructive jaundice caused by a periampullary (pancreas, papilla, distal bile duct) tumor is associated with a higher risk of postoperative complications than in non-jaundiced patients. Preoperative biliary drainage was introduced in an attempt to improve the general condition and thus reduce postoperative morbidity and mortality. Early studies showed a redu...
