A receptacle having a plurality of interconnected chambers arranged to permit multiple process steps or processes to be performed independently or simultaneously. The receptacles are manufactured to separate liquid from dried reagents and to maintain the stability of the dried reagents. An immiscible liquid is included to control loading of process materials, facilitate mixing and reconstitution of dried reagents, limit evaporation, control heating of reaction materials, concentrate solid support materials to prevent clogging of fluid connections, provide minimum volumes for fluid transfers, and to prevent process materials from sticking to chamber surfaces. The receptacles can be adapted for use in systems having a processing instrument that includes an actuator system for selectively moving fluid substances between chambers and a detector. The actuator system can be arranged to concentrate an analyte in a sample. The detector can be used to detect an optical signal emitted by the contents of the receptacle.

Systems and methods for dispersing oxidizing agents in the atmosphere to effect conversion of atmospheric methane to carbon dioxide are described. The system includes oxidizing agent delivery systems, elevated dispersion systems and associated control systems to control dispersion based on current and/or modelled atmospheric composition, atmospheric conditions and location specific parameters.

A colorimeter, webcam, camera, spectrophotometer, scanner or other instrument measures the color composition and conditions and texture of a person's body part or presented beauty product and an individual custom formulation is produced. A presented beauty product may include foundation, concealer, tinted moisturizer, primer, skin care products, blush, nail polish, hair dye, lipstick, lip gloss, mascara, eye liner and eye shadow. The produced custom formulation may comprise foundation, concealer, tinted moisturizer, primer, skin care products, blush, nail polish, hair dye, lipstick, lip gloss, mascara, eye liner, eye shadow or other consumer products. A computer system 301 includes a processor 501 and a non-transitory, computer readable medium 500 containing machine readable instructions that accept data from a colorimeter 300 or like instrument and uses a main executable program 502 and a subroutine 504 for color analysis.

Disclosed is a method for preparing a stable fluid mixture by mixing hydrophilic and hydrophobic substances using ultrasound wherein homogeneous dispersion and mixing are possible so that dispersibility is greatly improved and separation between the hydrophilic and hydrophobic substances is minimized even after a long time.

The apparatus for dispersing and mixing fluids by focused ultrasound includes a fluid storage unit for storing a fluid mixture of at least two fluids comprising a hydrophilic substance and a hydrophobic substance, the fluid storage unit comprising a first connector and a second connector connected to a fluid flow path such that the fluid mixture moves through a fluid flow path providing a portion through which the fluid mixture moves, a fluid dispersion unit for focusing ultrasound to a portion of the fluid flow path to disperse fluids contained in the fluid mixture by ultrasound when the fluid mixture moves the portion, and a fluid circulation unit for circulating the fluid mixture such that a portion of the fluid mixture relatively insufficiently dispersed is moved through the first connector from the fluid storage unit to the fluid dispersion unit and the fluid mixture dispersed by the fluid dispersion unit is moved through the second connector to the fluid storage unit.

A solution management system (1) for bioprocessing, wherein each flow path formed between solution inlets (2) and solution outlets (9) of the system comprises one or more bend sections having an inner cross-sectional area and/or an inner cross-sectional geometry and/or a centre line radius varying along the length of the bend section. Various embodiments of the solution management system (1) provide for improved laminar fluid flow with a reduced pressure drop between the solution inlets (2) and solution outlets (9) therein.

A winder for forming a yarn package can have a spindle axis. The winder can comprise a spindle that is configured to be rotatably driven about the spindle axis. A color probe can be positioned with respect to the spindle to measure a color value of yarn wound on the spindle.
