A low-power atmospheric pressure plasma source, comprising a plasma-forming region for injection of a plasma-forming gas; an excitation region for injection of a source of reactive species downstream of the plasma-forming region; and a narrow converging plasma exit for producing a narrow plasma jet, the source being electrically decoupled from a substrate under treatment by the plasma jet. The present source may find applications for example for skin treatment, etching of skin cancer cells, deta...

Food grade colored fluids which include food grade dyes and food grade glycols are provided. Also provided are methods for applying the food grade colored fluids directed to the surface of an edible substrate, and edible substrates having the food grade colored fluids applied to a surface thereof. The food grade colored fluids may optionally include glycerine and water. In one embodiment, the food grade glycol makes up at least about 25 wt. % of the colored fluid and water makes up no more than ...

Food grade colored fluids which include food grade dyes and food grade glycols are provided. Also provided are methods for applying the food grade colored fluids directed to the surface of an edible substrate, and edible substrates having the food grade colored fluids applied to a surface thereof. In some embodiments the food grade colored fluids include a surface tension modifier to reduce their surface tensions. The food grade colored fluids may optionally include glycerine and water. In one e...

A computer graphics system generates a pixel value for a pixel in an image, the pixel being representative of a point in a scene as recorded on an image plane of a simulated camera, the computer graphics system being configured to generate the pixel value for an image using a selected ray-tracing methodology in which simulated rays are shot from respective ones of a plurality of subpixels in the pixel, each subpixel having coordinates (s.sub.x,s.sub.y) in the image plane The computer graphics sy...

A method of operating a corona discharge device includes producing a high-intensity electric field in an immediate vicinity of at least one corona electrode and continuously or periodically heating the corona electrode to a temperature sufficient to mitigate an undesirable effect of an impurity, such as an oxide layer, formed on the corona electrode.

A colorant from a natural source which produces a wide range of stable colors in food and beverages which have a pH range of 2.0 to about 8.0 is added to foods and beverages in effective proportion. The colorant is the anthocyanin from `Heavenly Blue` Morning Glory, peonidin 3-(dicaffeylsophoroside)-5-glucoside.

The present inventors found that a natural red pigment can be obtained from hemoglobin and myoglobin whose metalloporphyrin moiety is zinc protoporphyrin, and made meat products, whale meat products, fish meat products and fish paste products that were colored with the natural red pigment. Consequently, it was possible to obtain food products stable to oxidation and exhibiting an excellent color tone without the need to use a color fixative, e.g. nitrite.

A method and apparatus for testing the random numbers generated by a random number generator in real time. As a series of random numbers are generated, a plurality of the last numbers are stored, then the stored random numbers are shifted by predetermined amounts to obtain a special kind of dot product of bit sequences between the stored random numbers and the shifted random numbers. The average autocorrelation values are computed each time a new random bit is generated. Thereafter, it is determ...

Food products having a nut-like texture e.g., simulated nutmeats, are prepared by forming a homogeneous dispersion comprising a continuous phase composed of a hydrophilic film-former in which is suspended droplets of fat or oil. The film-former can comprise an aqueous protein suspension. The dispersion is mixed under a vacuum. The resulting mixture contains sufficient moisture to give it the consistency of a shape-retaining plastic mass. The plastic mass is formed into a predetermined shape and ...

A process for modifying the taste and/or odor properties of a food coloring substance having unpleasant taste and/or odor properties is disclosed. There is also provided a process for obtaining a blue non-bleeding color that seems approvable by most health authorities. The invention is useful in food products, sweets and pharmaceutical products ingested orally.
