Abstract: The disclosure provides for CRISPR-Cas-based detection of SARS-CoV-2 using recombinase polymerase amplification, and uses thereof.

Abstract: A display which includes a plurality of sub-pixels each split into a plurality of sub-regions. Each sub-pixel includes a single gate line and a single signal line, and each sub-region within a given sub-pixel includes a corresponding storage capacitor line. An optical element cooperatively combines with the plurality of sub-pixels to create distinct angularly dependent brightness functions in association with corresponding sub-regions within the sub-pixels. Control electronics are configured to provide image data levels in the form of signal data voltages to each sub-region included within each sub-pixel via the gate line and signal line included within the sub-pixel; and to independently modify the signal data voltages provided to each sub-region within the sub-pixels via the corresponding storage capacitor lines whereby the display operates in accordance with at least two different image functions.

Abstract: In the manufacture of a wax pattern for use in the lost wax casting of a bladed rotor of the radial flow type, the bladed region of a master pattern is enclosed by a curable epoxy resin/aluminium powder composition. Sufficient of the cured resin composition is then machined away so that a plurality of resin composition segments are defined, one segment being interposed between adjacent blades on the master pattern. The segments are then removed from the master pattern and placed in an appropriately configured die member so as to define a complete die for the production of a wax pattern in the form of the master pattern.

Abstract: A new form of chewing tobacco in cake form but with a low tensile strength such that it may be easily torn, broken, or bittin into smaller pieces.
