Abstract: The present disclosure provides a method for detecting short-chain fatty acids in biological samples, including a derivatizing step, a loading step and a detecting step. The derivatizing step includes treating the short-chain fatty acids in the biological sample with 2-nitrophenylhydrazine for derivatizing the short-chain fatty acids into a sample to be detected. The loading step includes loading the sample onto a paper carrier. The detecting step includes analyzing the sample loaded onto the paper carrier by direct analysis in real time mass spectrometry for obtaining a detection result. The method provided by the present disclosure may complete the analysis of the biological sample within a short period of time and achieve a quantitative result comparable to that obtained by conventional chromatographic approaches.

Abstract: A system for use in a poultry house includes a control server, a network gateway disposed in the poultry house and equipping with a wireless communication capability; a movable sensor module disposed in the poultry house, wherein the movable sensor module is movable within the poultry house for obtaining a plurality of environmental parameters associated with specific locations within the poultry house, and a sampling machine disposed in the poultry house for obtaining a sample of poultry waste on the ground of the poultry house. The movable sensor module transmits the environmental parameters to the network gateway, and the network gateway transmits the environmental parameters to the control server for processing the environmental parameters.

Abstract: The invention encompasses devices and methods that at least partially entrap the droplets and aerosols from a person undergoing an aerosol/droplet-generating procedure, thereby reducing a heath care worker's direct exposure to such health hazards. The device includes a planar cover structure impermeable to aerosols, droplets, fluids and gas. The planar cover structure providing a barrier between a health care worker and the body cavity or orifice of a patient. A hollow tubular extension forming an opening on the planar cover structure and the opening is configured to he positioned approximately on top of the body cavity or orifice of the patient. The opening configured to be reversibly closed via a closure mechanism.

Abstract: A use of an anthranilic acid derivative as a matrix for a MALDI Mass spectrometry, comprising: preparing a matrix compound represented by the following formula: wherein X is selected from hydrogen and a hydroxyl group, and Y is selected from hydrogen, a methyl group or an acetyl group, provided that when X is hydrogen, Y is hydrogen or an acetyl group, and when X is a hydroxyl group, Y is a methyl group; applying the matrix compound and an analyte onto a sample holder; and analyzing the analyte by the MALDI mass spectrometer.

Abstract: A LCD driving system for increasing LCD response times. Voltages across liquid crystals are increased by modulating gamma reference voltages fed to a data driver, modulating image codes fed to the data driver, or both. Particularly, around the highest and the lowest image code, modulation of gamma reference voltages fed to a data driver is most effective.
