Slow continuous ultrafiltration (SCUF) is an artificial method which approximately mimics the ultrafiltration function of the kidneys. SCUF is a continuous renal replacement therapy (CRRT) generally used to remove fluid from fluid overloaded patients with acute kidney failure. During SCUF blood is continuously removed from the body, passed ...
Hemofiltration is sometimes used in combination with hemodialysis, when it is termed hemodiafiltration. Blood is pumped through the blood compartment of a high flux dialyzer, and a high rate of ultrafiltration is used, so there is a high rate of movement of water and solutes from blood to dialysate that must be replaced by substitution fluid that is infused directly into the blood line.
For emphasis, the text is bolded and surrounded by a black outline. In the United States , a boxed warning (sometimes " black box warning ", colloquially) is a type of warning that appears near the beginning of the package insert for certain prescription drugs , so called because the U.S. Food and Drug Administration specifies that it is ...
The earliest identified reference to "black boxes" occurs in a May 1945 Flight article, "Radar for Airlines", describing the application of wartime RAF radar and navigational aids to civilian aircraft: "The stowage of the 'black boxes' and, even more important, the detrimental effect on performance of external aerials, still remain as a radio ...
Ultrafiltration (UF) is a variety of membrane filtration in which forces such as pressure or concentration gradients lead to a separation through a semipermeable membrane. Suspended solids and solutes of high molecular weight are retained in the so-called retentate, while water and low molecular weight solutes pass through the membrane in the ...
An example of a homemade unit. The Corsi–Rosenthal Box is a design for a do-it-yourself air purifier that can be built comparatively inexpensively. It consists of four [1] or five [2] [3] HVAC particulate air filters that form a cube and a box fan to draw air through the filters.
[3] The suspended liquid is passed through at a relatively high velocity of around 1–3 m/s and at low to moderate pressures (around 100-400 kPa) parallel or tangential to the semi-permeable membrane in a sheet or tubular form. [4] A pump is commonly fitted onto the processing equipment to allow the liquid to pass through the membrane filter.
8-, 5.25-, 3.5-, 2.5-, 1.8- and 1-inch HDDs, together with a ruler to show the length of platters and read-write heads A newer 2.5-inch (63.5 mm) 6,495 MB HDD compared to an older 5.25-inch full-height 110 MB HDD. IBM's first hard drive, the IBM 350, used a stack of fifty 24-inch platters and was of a size comparable to two large refrigerators.
