Disclosed are fibers which contain identification fibers. The identification fibers can comprise one or more chemical markers, or taggants, which may vary among the fibers or be incorporated throughout all of the fibers. The disclosure also relates to the method for making and characterizing the fibers. Characterization of the fibers can include identifying chemical markers and correlating the chemical markers and a taggant chemical marker amounts of at least one of the chemical markers to manufacturer-specific taggants to determine supply chain information. The supply chain information can be used to track the fibers from manufacturing through intermediaries, conversion to final product, and/or the consumer.

Disclosed is a rotary valve 1 comprising a stator 20 and a rotor 40 generally in rotary sliding engagement with the said stator about a valve axis RA, the stator including a plurality of fluid ports 22, 26, 28, the rotor 40 being operable to selectively fluidically interconnect two or more of said ports during its rotary sliding engagement. The valve further includes an actuator (70) for disengagement of the rotor from the stator to enable efficient cleaning of the valve interconnections.

A medical diagnosis screens a biomarker for lung cancer detection by utilizing serum metabonomics. The medical diagnosis includes a biomarker for differential diagnosis between patients with lung cancer and healthy people, and between patients with lung cancer and patients with benign pulmonary nodules, and a biomarker for differential diagnosis between patients with lung cancer and healthy people, and between patients with lung cancer and patients with benign pulmonary nodules according to gender differences between a man and a woman. The biomarker is of great significance especially in the differential diagnosis of whether a patient with nodules in the lung has lung cancer.

Ion exchange stationary phases are prepared with diprimary diamines for applications such as separating samples that contain polyvalent anions. The ion exchange stationary phase includes a series of condensation polymer reaction products bound to a substrate. The condensation polymer products are formed with diprimary diamines and polyepoxide compounds. The ion exchange stationary phases described herein are capable of separating monovalent and highly polyvalent anions relatively quickly with relatively low eluent concentrations in one chromatographic run.

A method for concentrating electrically charged objects in a non-Newtonian liquid medium comprises: feeding a sample containing electrically charged objects into a channel having a flow axis, a first transverse cross-section orthogonal to the flow axis, and at least one second transverse cross-section orthogonal to the flow axis, one dimension of the second cross-section being less than the corresponding dimension of the first cross-section; and applying a hydrodynamic flow in a direction of the channel together with the application, in the opposite direction, of an electric field in the channel, thus making it possible to move the electrically charged objects in the channel along the flow axis from the first cross-section to the second cross-section, stop the objects, and concentrate the objects in at least one area upstream from the second transverse cross-section.

A wearable health monitoring device includes a band configured to attach the wearable health monitoring device to a user's body; a VOC detection device configured to collect and analyze volatile organic compounds given off from the user's skin to identify specific health-indicative volatile organic compounds indicative of a health condition; and a biomarker sensor configured to detect a biomarker of the user.

A chemical reactor is implemented on a substrate and has an inlet for receiving a fluid and/or a gas; a filter element for reducing or preventing that materials cause a blockage in the fluid supplied and/or the gas supplied in a part of the chemical reactor located further away; and a part located further away for transporting and/or processing the fluid and/or the gas. The part located further away has a depth dlow smaller than the depth dhigh of the inlet. The filter element has a first duct part and a second duct part; the first duct part is positioned closer up against the inlet than the second duct part, the first duct part is deeper than the second duct part, the first duct part has a diverging width and is free from pillar structures, and the second duct part is filled with filter pillars.
