Abstract: A method for locally serving content is described. The method includes receiving, at a gateway device, a first request for a data file via a first user device communicatively coupled to the gateway device. The data file is received at the gateway device from an external server and sent to the first user device. A data record is stored to a storage device indicating that the data file has been sent to the first user device. A second request for the data file is later received at the gateway device from a second user device communicatively coupled to the gateway device. In response to the receiving of the second request, the data record is accessed and causes a computer read of the data record. The first user device is then instructed to transfer the data file to the second user device, via the gateway device, based upon the computer read.

Abstract: Techniques disclosed herein can be used to perform a rapid, splitless injection of a sample including SVOCs and VOCs. In some embodiments, a system includes two focusing traps combined in series, one inside of a GC oven and one in a separate oven to concentrate the SVOCs inside of the GC oven and concentrate the VOCs outside of the GC oven. Heating the VOC focusing trap and reversing the flow through both focusers allows splitless injection of compounds boiling from as low as ?100° C. to as high as 600° C. in a single analysis, with a narrow injection bandwidth to optimize both sensitivity and the resolving power of the analyzer.

Abstract: A vehicle drive unit assembly includes an axle extending between a pair of wheels, a braking system for slowing and stopping the vehicle, and a retarding system located on the axle for assisting the braking system. The axle has a housing and an axle shaft that receives input from an engine and driveshaft to drive the wheels. The braking system includes a brake member supported on each of the wheels and an actuator for selectively moving the brake members between an unactuated position and an actuated position. The braking system produces a braking force to slow or stop the rotation of the wheels when the brake is in the actuated position. The retarding system includes a plurality of magnets supported for rotation with the axle shaft and an inductor held fixed to the axle housing. The retarding system produces a retarding force as the magnets rotate with respect to the inductor to slow the rotation of the wheels when the actuator moves the brake members to the actuated position.

Abstract: The extraction of Factor VIII, the antihaemophilic factor in blood, is difficult due to its instability and the presence of impurities. An initial Factor VIII containing aqueous solution such as blood plasma is purified by subjecting a Factor VIII containing aqueous migrant solution to continuous flow electrophoresis wherein flow takes place in an annular separation chamber and is stabilized by means of an angular velocity gradient; and collecting a separated Factor VIII component.In order to separate the Factor VIII from albumin and firbrinogen, while obtaining good recoveries of Factor VIII (e.g. .about.60%), the migrant solution is prepared by precipitating Factor VIII from the initial solution using ethanol, and removing and redissolving the precipitate in an aqueous medium and adjusting the pH to be within the range of 7.5 to 8.6, preferably 8.3 to 8.6.
