摘要:
A system for spatially selective, fixed-optics fluorescence detection in a multichannel polymeric microfluidic device, and a method for performing spatially selective, fixed-optics fluorescence detection.
摘要:
A support assembly is disclosed generally including a buckle component or components and a positioning member of flexible material that is arranged and configured to support the buckle component in a predetermined elevated position or predetermined positions for multiple components while also allowing for resilient shifting thereof. In the preferred form, the flexible material is belt webbing that has a plurality of fold portions folded and sewn together in a specific manner. Sew patterns are disclosed as well as methods and fixtures for forming the belt webbing positioning member.
摘要:
A process for the regeneration of loaded ion-exchange resin comprising (a) providing loaded resin for regeneration; (b) providing first stage and third stage regenerant suitable for regenerating loaded resin; (c) providing a plurality of regeneration vessels; (d) filling a regeneration vessel with a desired amount of the loaded resin before filling another regeneration vessel; (e) once a regeneration vessel has been filled, contacting the loaded resin within the vessel with first stage regenerant in a plug flow to provide a first stage regenerated resin; (f) contacting the first stage regenerated resin with third stage regenerant in a plug flow to provide regenerated resin and (g) removing and collecting third stage regenerant from a vessel containing regenerated resin and adding the collected regenerant to the first stage regenerant.
摘要:
A fixed-optics system for detecting fluorescence light emitted from one or more spatially selected volumes (S), e.g., in one or more microfluidic channels, comprises a detection optical fiber (60) corresponding to each selected volume and a ball lens (110) adjacent to one end of each optical fiber, wherein the ball lens has a diameter (D) larger than the diameter of the optical fiber and a distance (d1) between the ball lens and the optical fiber is in a range of 3 to 40 times the diameter of the optical fiber, so that due to a quasi-focusing configuration light emitted from the spatially selected volume and received by the ball lens converges onto the end (60a) of the optical fiber.
摘要:
A clothing packing apparatus for folding a clothing article, such as a suit, comprising a spacing material to separate parts of the folded clothing article comprises a parts that partial overlay a fold line in the aligned sleeves and the body of an article of clothing; a slit for folding the sleeves independently; gripping surfaces to engage the clothing article; rounded/tapered edges to eliminate pressure compressions; pre-formed bands to improve folding performance; and a casing for storage and transit. The spacing material is preferably formed of foam capable of forming a continuous U-shaped curve along the fold lines and an anti-collapsible structure when folded with the clothing article.
摘要:
Methods and apparatus enable reliable and improved isolation between two portions of a bore extending through a casing string disposed in a borehole. A downhole deployment valve (DDV) may provide the isolation utilizing a valve member such as a flapper that is disposed in a housing of the DDV and is designed to close against a seat within the housing. The DDV includes an operating mechanism for opening/closing the DDV. In use, pressure in one portion of a well that is in fluid communication with a well surface may be bled off and open at well surface while maintaining pressure in another portion of the casing string beyond the DDV.
摘要:
Melt-processible, thermoplastic poly(tetrafluoroethylene) (PTFE) compositions are disclosed and methods for making and processing same. Additionally, products comprising these compositions are described.
摘要:
The present invention generally relates to chemotherapeutic treatment of proliferative disorders, such as cancer. The invention more specifically relates to inhibition of pan-cell cycle progression with alkylating anthraquinones, which may inhibit mitotic commitment, lead to limited expression of G2 arrest and force cells to enter polyploidy via an aberrant mitosis. The methods of the invention are particularly useful in the treatment of chemotherapy-resistant cancers.
