Abstract: A device and a method for image zooming are provided, in which two FIFO buffer units and a read/write control unit are added between a data storage unit and an image zooming unit. The read/write control unit respectively controls two FIFO buffer units to obtain and output the gray values of the pixels on the two adjacent channels to the image zooming unit in parallel. Then, the image zooming unit calculates gray values of pixels to be inserted between the two adjacent channels to finish interpolation. The image zooming unit need not read the gray values of the pixels on the two adjacent channels in the zooming direction from the data storage unit in series and in turn, but instead, may simultaneously read the gray values of the pixels on the two adjacent channels to pixels to be inserted from the two FIFO buffer units in parallel.

Abstract: Non-basic and non-acidic homogeneous catalysts organo-metallic compound of the formula: M(OCH3)x wherein M is B, Na, Mg, K, Ca, Sc, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Ga, Ge, Al, Sn, Sb, Mo, Ag, and Cd and x is an integer from 2, 3 or 4 can catalyze transesterification of oils and fats having high free fatty acid content and with an acid number from 0.5 to 20, into biodiesel. B(OCH3)3 and Ge(OCH3)4, having low boiling points, are easily recovered from the biodiesel and glycerol phases and recycled for reuse. Continuous biodiesel production with the novel homogenous catalysts is achieved without the complicated and troublesome steps attendant with conventional processes using base or acid homogeneous catalyst. The high purity biodiesel is produced without acid-base neutralization, water wash, filtration, and solid disposal steps for removing the spent catalyst from the product streams associated with prior techniques.

Abstract: Partial oxidation of crumb rubber derived from environmental hazardous waste tires yields surface treated crumb rubber which are used as blending stocks for making rubberized concrete with substantially improved mechanical strength as compared to the conventional rubberized concrete. The chemically more active rubber surface becomes hydrophilic, so it interacts with the hydrophilic surface of surrounding cement matrix much stronger. The mechanically improved rubberized concrete is more versatile than conventional rubberized concrete.

Abstract: Catalytic partial oxidation using a metal oxide catalyst surface treats crumb rubber that is recovered from waste rubber tires. Advantages of using catalytically oxidized crumb rubber relative to using non-catalytically oxidized crumb rubber in making the rubberized concrete, includes superior mechanical strength and water-repealing capability, lower oxidation temperature and shorter oxidation time, and accelerated hydration times. Rubber oil (a gas condensate) co-produced from the crumb rubber partial oxidation process is equal to or better than the commercial superplasticizers. Industrial scale partial oxidation employs a continuous flow tubular reactor where a crumb rubber/catalyst mixture is fed into the reactor co-currently with an air/nitrogen mixture.

When the input power is greater than the reference value, the controller controls the first lighting module, the second lighting module, and the rectifier to form a second connection state. Also, a controlling method of the lighting apparatus is disclosed.

Abstract: Partial oxidation of crumb rubber derived from environmental hazardous waste tires yields surface treated crumb rubber and a gas condensate which are used as blending stocks for making rubberized concrete with substantially improved mechanical strength as compared to the conventional rubberized concrete. The chemically more active rubber surface becomes hydrophilic, so it interacts with the hydrophilic surface of surrounding cement matrix much stronger. The gas condensate co-produced in the partial oxidation reactor consists of mainly active sulfur oxides (R—SOx—R) and serves as an excellent bonding agent to further enhance the bonding strength between the partially oxidized rubber particles and the cement mixes. The mechanically improved rubberized concrete is more versatile than conventional rubberized concrete.

The valve is mounted slidably in the tube and selectively seal the at least one outlet hole. The clip is mounted detachably around the tube of the base and cooperates with the clipping flange to hermetically clip the sheet of the bag. The vacuum valve device may be reused, is economical and marketable.
