switches are playing a significant role in a number of applications today.
Designed to detect
the T790M mutation in exon 20 of the epidermal growth factor receptor (EGFR) gene, the new assay will allow drug developers to investigate its reported association with acquired resistance and can act as a useful tool to predict drug response.
What that means is you need more-sensitive assays" to detect
the molecules' presence, he says.
The camera looks forward and detects
lane markers in the road.
This is actually the most difficult fault to detect
because of the numerous angles in which a broken wire can be laying on the web and thereby generating a large variety of signal types and amplitudes.
This additional time allows the otolaryngologist to detect
any re-emergence of pathogens that were not eradicated.
Conventional metal detectors are used for most de-mining, but they are notoriously slow and inaccurate because they respond to all metal objects and don't detect
most new landmines, which come covered in plastic.
Handheld and small area detectors usually detect radiation with sodium iodide and are less sensitive than large area portal systems.
Troops can place these on their uniforms or vehicles to detect
nerve gas or blister-causing compounds.
Furthermore, scientists can design sensors to detect
mixtures that even in high concentrations are odorless to people.
A doppler device detects
the resulting tissue motion, and a video screen displays a color "map" of the contrasting vibrational patterns.
In many cases, these sensors are based on enzymes that are isolated from biological sources and purified before they are coated onto the surface of an electrode that detects
a chemical either produced or consumed during the enzymatic reaction.
