A quantum pipette
Curved quantum waveguides are known to bind particles. We show that a number of charged fermions in such a trap can be tuned by an external electrostatic eld; if the latter is slowly increased, the bent duct can serve as a single particle ejector.
متن کاملA mechanical pipette.
An automatic pipette is a very useful equipment for any laboratory carrying out Kahn tests on a large number of sera. A number of devices were tried in a field laboratory which was functioning as a serological laboratory for the CeylonArmy Command during the years 1945 and 1946. A mechanical pipette which can easily be prepared with materials salvaged from a small workshop is described below. T...
متن کاملA multifunctional pipette.
Microfluidics has emerged as a powerful laboratory toolbox for biologists, allowing manipulation and analysis of processes at a cellular and sub-cellular level, through utilization of microfabricated features at size-scales relevant to that of a single cell. In the majority of microfluidic devices, sample processing and analysis occur within closed microchannels, imposing restrictions on sample...
متن کاملA discrepant urine specific gravity.
A 21-year-old man presented after being struck by a car and underwent a computed tomography scan of the chest and spine. Three hours later, his clear yellow urine sample was sent to the laboratory. A routine urinalysis with the Roche Urisys® 2400 indicated the specific gravity (SG) as a flag, i.e., an error for SG. A manual repeat of the SG measurement was also not readable by refractometer (no...
متن کاملLow specific gravity syndrome.
Data strongly suggestthat the longer patients have been treated in New Castle State Hospital, the higher the probability that they will demonstrate the low specific gravity syndrome. It is believed that a probably unrecognized alteration in human water metabolism among institutionalized patients who have chronic, severe epilepsy and who have been administered anticonvulsant drugs for many years...
