New model possibility pumping antibiotics bacteria
2017/11/23
Researchers in the University of Wisconsin–Madison Department of Biochemistry have discovered that a cellular pump known to move drugs like antibiotics out of E. coli bacteria has the potential to bri...
Pumping human milk in the early postpartum period: its impact on long-term practices for feeding at the breast and exclusively feeding human milk in a longitudinal survey cohort
human milk infant feeding lactation milk expression pumping
2018/11/29
Background: Most American mothers who feed human milk (HM) now use pumps to produce some of the HM they feed. Pumping is nationally recommended, but associations between pumping and HM-feeding duratio...
ENVIRONMENTAL IMPACT ASSESSMENT OF MINING RELATED DEWATERING ACTIVITIES USING INTEGRATED INSAR,OPTICAL REMOTE SENSING AND PUMPING DATA
Interferometric SAR EIA Subsidence Dewatering Mining
2015/12/30
Open pit mining sometimes intercepts highly permeable zones, with resulting high inflows of water into the excavation area. This remains a major problem in the mining industry and requires constant mo...
Regional Differences in the Role of Eddy Pumping in the North Atlantic Subtropical Gyre: Historical Conundrums Revisited
Eddy Pumping Historical Conundrums Revisited
2015/7/20
The vast subtropical regions of the ocean account for at least 30% of the carbon export to the deep ocean. It is predicted that these regions will get larger as a consequence of global warming. Tradit...
Pore-water exchange driven by tidal pumping causes alkalinity export in two intertidal inlets
intertidal inlets idal pumping
2014/10/16
Carbon (C) and alkalinity export from two adjacent intertidal inlets with different terrestrial inputs was
investigated. One inlet receives a small creek from an agriculturally dominated catchment, l...
Pumping speed of cryopump for xenon
vacuum plume large-diameter external cryopump xenon pumping speed test
2015/8/11
The xenon pumping speed testing system of the large-diameter external cryopump was designed to meet the plume test requirements for prototype electric propulsion. The flowmeter method was utilized to ...
Groundwater Over-Pumping and Recent Earthquakes in the Northern United Arab Emirates: A Natural Hazard Accentuated by Human Activity
Groundwater Over-Pumping Earthquakes Northern UAE Human Impact
2013/3/19
At the present day the United Arab Emirates (UAE) is on the flank of the Arabian plate, but some way away from the major modern earthquake epicentres. It normally experiences only minor earthquakes wh...
Behavioral Variations of Gain and NF Owing to Configurations and Pumping Powers
Double Pass Single Pass Erbium Doped Fiber Configuration Pumping Power
2013/1/30
Six configurations are proposed in this paper to explore the gain and noise figure (NF) variations under the pumping power effect. I propose a new investigation of gain and NF at different EDFA config...
