摘要:
Transfecting biology cells with nucleic acid molecules (DNA, siRNA) is an essential prerequisite in elucidating how genes function in complex cellular context and how their activities could be modulated for therapeutic intervention. Traditionally studies are carried out on a low throughput gene-by-gene scale, which has created a huge bottleneck in functional genomic study and drug discovery. Development of high-throughput cell transfection technology will permit functional analysis of massive number of genes and how their activities could be modulated by chemical or biological entities inside cells. This invention describes design, construction of device and apparatus for high throughput effective cell transfection. Procedures and protocols for using the device and apparatus are also described in the application. Novel methods of using the device in cell-based assays are also disclosed.

A method for updating web pages on a web server without republishing the web pages involves providing on a production database server a live version of one or more business data tables containing information used to populate web pages on a production web server and storing in a quality assurance database server a quality assurance version of the business data tables that can be used to populate pages on a quality assurance web server. A maker at a business workstation can access the quality assurance database server from time to time and enter a change to data on the quality assurance version of the business data tables. Thereafter a checker at a business workstation accesses the quality assurance database server to review and approve or reject the changes to the data on the quality assurance version of the business data tables, and if the checker approves the changes, the changes to the data on the quality assurance version of the business data tables are replicated from the quality assurance database server to the live version of the business data tables on the production database server.

The compositions and methods are provided that enhance the selection of transgenic plants having two T-DNA molecules integrated into a plant genome at different physical and genetic loci. The compositions are DNA constructs that comprise novel arrangements of T-DNA molecules containing genes of interest, positive selectable marker genes, and conditional lethal genes. The methods disclosed herein comprises transforming a plant cell to comprise the DNA constructs of the present invention, regenerating the plant cell into a plant and identifying independant transgene loci, where the selectable marker genes or transgenic elements can be segregated in the progeny.

A method of colour saturation compensation in a video signal is disclosed. The method includes the steps of: processing a luminance signal component of the video signal; determining whether the processing of the luminance signal results in a change in chrominance saturation; if the step of determining reveals that the chrominance saturation has changed, applying a chrominance compensation signal to the chrominance signals to counteract the effects of chrominance saturation, wherein said step of applying a compensation signal include the steps of: generating a compensation signal which is dependent on hue and luminance ratio (output luminance signal/input luminance signal). Apparatus for performing the method is also disclosed.
摘要:
A swashplate type compressor that includes one or more pistons having an extra support surface for receiving a side load is provided. In a first preferred embodiment of the piston, a rotational restrictor that overlaps the head region is utilized as the extra support surface. In a second preferred embodiment, a support projection, separate from the head region, is utilized as the extra support surface. The extra support surface of the piston of the present invention receives a portion of the side load exerted on the piston, thereby relieving some of stress applied to the head region.
摘要:
A variable displacement swash plate type compressor which incorporates a lubrication passage formed in the drive shaft, wherein the lubrication passage provides fluid communication between a discharge chamber and a crank chamber. The lubrication passage maximizes the low of refrigerant gas and lubricating oil to the crank chamber under all operating conditions providing cooling and lubrication to the internal moving components in the crank chamber. The lubrication passage facilitates the efficient flow of lubricating oil from the discharge chamber to the crank chamber.

A compressor (10) for a vehicular air conditioning system includes a cylinder block (12) having a bore (14). A piston (78) is slidingly received in the bore (14). A cylinder head (16) is mounted on the cylinder block (12) and includes a suction chamber (20) and a discharge chamber (22). A valve plate (18) is provided between cylinder block (12) and the cylinder head (16). The valve plate (18) includes a suction port (26) and a discharge port (35). A suction valve (28) cooperates with the suction port (26) to permit refrigerant to enter the bore (14) from the suction chamber (20). The suction valve (28) includes a terminating portion (28A) and a flexing portion (28B). A recess (32) is formed in the cylinder block (12) adjacent the flexing portion (28B) of the suction valve (28). The recess (32) provides a linear clamping line (C) on the suction valve (28) between the valve plate (18) and the cylinder block (12).
摘要:
A multiple port reflection based circulator using a thermally expanded multiple core fiber. The circulator includes optical components to separate, rotate, and combine orthogonally polarized components of light in order to propagate light in one direction among consecutive cores of the fiber. The first and last cores of the fiber also being consecutive cores. The thermally expanded multiple core fiber enabling coupling to the circulator without the use of lenses.
