An optical header for coupling an edge emitter light source to an optical fiber is disclosed. The header preferably includes a ceramic or silicon substrate that has a recess for an edge emitting laser. An optical fiber is preferably attached to a substrate and terminates at a light source. The optical fiber is oriented such that the elliptical beam of light produced is situated such that the longer axis of the elliptical beam is orthogonal to the optical fiber. The header is particularly useful when used in conjunction with an optical receiver to form a bidirectional optical transceiver.

A flexible hermetic sealing and method for making the same. Electronic components are coated with an adhesive such as an epoxy, and then a metallic layer consisting of gold, silver, nickel, or another metal is deposited thereon. The metal may be deposited by, for example, any well-known evaporating, sputtering or plating technique. The resultant seal is truly hermetic, and is suitable for use on individual electronic or optical components on a chip.

A computer program product is provided for managing workload in a computer system. Computer usable program code cause a first compute node to broadcast a workload bid request to a plurality of compute nodes, wherein the workload bid request includes workload parameters. The compute nodes each receive the request from the first compute node, and each compute node uses the workload parameters to calculate a cost of running the workload. One or more individual compute nodes within the plurality of compute nodes send a workload bid to the first compute node, wherein each workload bid includes the cost of running the workload on the individual compute node sending the workload bid. The first compute node receives and uses each workload bid to select a target compute node to run the workload, wherein the target compute node is selected from the individual compute nodes and the first compute node.

A process and an apparatus for separating and recovering waste alkali from a cyclohexane oxidation solution are provided. A gradient combination of the gravity separation technique, the vortex separation technique and the coalescence separation technique is used to carry out fine separation of the waste alkali liquor from the cyclohexane oxidation solution. The purified cyclohexane oxidation solution is fed into a down-stream apparatus. Most of the waste alkali liquor thus separated is recycled, while the remaining is expelled. The expelled waste alkali liquor is incinerated in an incinerator, followed by recovering the molten species using a pneumatic pulverization process.

The subject DGAT2α polypeptide and nucleic acid compositions find use in a variety of applications, including research, diagnostic, and therapeutic agent screening applications, as well as in treatment therapies and in the production of triacylglycerols.
摘要:
The present invention relates to a process and an apparatus for separating and recovering the waste alkali from a cyclohexane oxidation solution, and provides a process and an apparatus for separating and recovering the waste alkali from a cyclohexane oxidation solution. According to the invention, a gradient combination of the gravity separation technique, the vortex separation technique and the coalescence separation technique is used to carry out fine separation of the waste alkali liquor from the cyclohexane oxidation solution. The purified cyclohexane oxidation solution is fed into a down-stream apparatus. Most of the waste alkali liquor thus separated is recycled, while the remaining is expelled. The expelled waste alkali liquor is incinerated in an incinerator, followed by recovering the molten species using a pneumatic pulverization process. According to the invention, the content of Na+ in the cyclohexane oxidation solution fed into the alkane tower can be lowered to less than 3 mg/L, and the molten species resulting from incineration can be recovered 100%. Thus, risk of environmental pollution by the waste alkali liquor is substantially eliminated. While the invention is well suited to separate and recover the waste alkali liquor from a cyclohexane oxidation solution, it may be adapted to other chemical engineering systems for separating and recovering waste alkali liquor as well.
