HPLC Troubleshooting Guide to Cycling Baselines and Pressure FluctuationsLCGCSpectroscopy
Though such previous fluidic separation systems can achieve acceptable separation performance, the integration of such systems within other components (including other components within certain larger fluidic systems) is generally difficult due to fluctuations in pressure downstream of the separation system, ...
Extraction Point Pressure Regulator serve to regulate compressed, liquefied and under pressure dissolved gases from supply grids (ring conducting) with a certain pre-pressure to the desired working pressure, in fact as independent of pre pressure or issue quantity fluctuations as possible. 抽气口调...
in U.S. Pat. No. 5,108,264 Method and Apparatus for Real Time Compensation of Fluid Compressibility in High Pressure Reciprocating Pumps, adjusts the pumping speed of a reciprocating pump by delivering the pumping fluid at high pressure and desired flow rate to overcome flow fluctuations. ...
The non-contact optical applanation tomometer used in common practice, however, has difficulty in achieving faithful IOP readout because of the nature of outside measurement, and cannot be deployed for regular monitoring of pressure fluctuations and treatment progress. Many microelectromechanical systems...
Over the course of evolution, plants have been experiencing abiotic changes, such as temperature fluctuations, that often lead to genetic adaptations to ensure survival. Several studies have investigated stress responses in plants to evaluate their resistance to cold and characterize the underlying molecul...
(Kent Scientific Corporation, CT, USA). Daily BP measurements were performed for at least 1 week before experiments in order to minimize stress-induced tail artery BP fluctuations. Rats were warmed for 10–20 min at 28 °C before the measurements to allow for detection of tail arterial ...
namely in the form of an argon plasma sheet formed by numerous argon filaments fluctuating within a limited quartz box volume, and therefore, its other benefit is its electrodeless operation. As it was shown in our previous paper51due to the argon plasma filaments fluctuations, parameters of the...
In a dietary intervention trial such as the present study, it is important to make an attempt to control for large fluctuations in diet. For this reason, the subjects were advised to maintain their normal diets during the duration of the study and not make any major changes. In addition, ...
Hypomethylation of long interspersed element (LINE)-1 has been observed in tumorigenesis when using degenerate assays, which provide an average across all repeats. However, it is unknown whether individual LINE-1 loci or different CpGs within one specifi
