摘要:
An apparatus comprising a nanowire waveguide with first and second ends, the second end comprising a nanoparticle, the nanowire waveguide configured to transmit radiation from the first end to the second end to illuminate the nanoparticle, the apparatus configured such that the nanoparticle is capable of being in close proximity to an analyte to allow for detection of said analyte.
摘要:
A method of deposition, the method comprising: providing an electrode pair and a fluid medium, the electrode pair comprising first and second electrodes configured to generate an alternating electric field therebetween, the fluid medium comprising a plurality of different types of particle dispersed therein; and setting one or more parameters of the alternating electric field to attract at least one type of particle from the fluid medium towards the electrode pair and deposit said at least one type of particle.

A process for preparing a low-lactose or lactose free mammalian milk product comprises the steps of enzymatically hydrolysing the lactose present in mammalian milk, diluting the milk with a lactose-reduced liquid, and adding one or more of a protein, a mineral, a vitamin, a gum, a starch, a stabiliser, and/or an emulsifier to the milk.
摘要:
A lavatory unit (10) comprising a tank body (12) connected to a pressurised water supply (20), and flushing means (14, 21, 23) for releasing water from the tank body via an outlet to a lavatory bowl (11). The flushing means includes an elastic bladder (21) the interior of which is in communication with the tank, the tank being generally sealed otherwise, such that the bladder stressed with the expansion of air forced from the tank as the tank fills with water and the bladder relaxes elastically as the tank empties, and thereby assists in ejecting the water under pressure from the tank to provide a better flushing action.
摘要:
A work piece positioning tool is disclosed. The tool includes a first leg and a second leg that have work piece abutting surfaces. Cooperative pivoting elements adjacent an end portion of each of the first and second legs are used for connecting the legs together in a plurality of relative angular orientations. The tool can be used in combination with first and second workpieces and first and second clamps to hold the first and second work pieces together at a desired angle.
摘要:
An integrated microfabricated instrument for manipulation, reaction and detection of microliter to picoliter samples. The instrument is suited for biochemical reactions, particularly DNA-based reactions such as the polymerase chain reaction, that require thermal cycling since the inherently small size of the instrument facilitates rapid cycle times. The integrated nature of the instrument provides accurate, contamination-free processing. The instrument may include reagent reservoirs, agitators and mixers, heaters, pumps, and optical or electromechanical sensors. Ultrasonic Lamb-wave devices may be used as sensors, pumps and agitators.
摘要:
A method for measuring the thickness of a thin film disk overcoat layer includes radiating x-rays on a thin film disk comprising at least one base layer and an overcoat layer, collecting fluorescence data on electromagnetic radiation fluoresced from the thin film disk, reflecting polarized light from a surface of the thin film disk corresponding to the overcoat layer, collecting ellipsometry data from the polarized light, and estimating the thickness of the overcoat layer using both the fluorescence data and the ellipsometry data. The method may further include providing a statistical model to determine optimal deposition and manufacturing parameters. A system to conduct the described method may include a data analyzer, an ellipsometry measurement device, and an x-ray fluorescence measurement device.

A guide strip removal system includes a pair of guide strip removal devices positioned on opposite sides of a printer outlet where a continuous sheet of paper is discharged. The guide strip removal devices each include a pair of plate members secured together in a spaced apart parallel relationship to define a narrow slot therebetween. The plate members each have a corner portion delineated from a planar main body portion by respective narrow slits that extend from front edges of the plate members toward rear edges thereof. The corner portions are angled away from the main body portions to create paths for the side edge guide strips that diverge abruptly away from paths for the marginal side edge portions of the printer paper. The side edge guide strips are thereby removed from the marginal side edge portions of the, paper without the use of any moving parts or cutting blades.
