Abstract: Microfluidic devices for cell sorting or cell fractionation are disclosed. A microfluidic device can comprise one or more inlets, a first wall and a second wall, and two or more outlets. The first and second walls can be substantially planar to each other and the first wall having can have a plurality of ridges protruding from the first wall and defining a compression gap between the ridge and a surface of the second wall. The microfluidic device can also be a cell sorting device for sorting a plurality of cells based on one or more biophysical cellular properties including size, elasticity, viscosity, and/or viscoelasticity wherein the cells are subjected to one or more compressions due to the compression gap. Also disclosed are methods for cell sorting based on a variety of biophysical cellular properties.

Abstract: Methods and apparatus for security protection domain-based testing. A testing framework enables the same certification tests to be run across different protection domains or operation modes, and on different platforms or devices. The testing framework may, for example, be directed to testing implementations of the Java Platform, Micro Edition (Java ME®) using Connected Device Configuration (CDC) or Connected Limited Device Configuration (CLDC) as the configuration layer and Mobile Information Device Profile (MIDP) as the profile layer. Different Mobile Information Device Profile (MIDP) specifications (e.g., MIDP 2.x and MIDP 3.x specifications) may be supported. The testing framework may be deployed in the context of compatibility testing and technology compatibility kits (TCKs). The testing framework may, for example, be applied in compatibility testing for Java ME® platform technology implementations.

Abstract: An apparatus for separating particles includes a first planar wall and a spaced apart second planar wall parallel to the first planar wall. The first planar wall and the second planar wall define a passage therebetween, which is disposed along a fluid flow axis. A first plurality of spaced apart elongated ridges extends into the passage from the first planar wall. The first plurality of spaced apart elongated ridges is disposed along a diagonal direction relative to the fluid flow axis. When a fluid is moved through the passage in a direction corresponding to the fluid flow axis, particles of a first type will tend to move in a first direction that is diagonally away from the fluid flow axis and particles of a second type, different from the first type, will tend to move in a second direction that is different from the first direction.

Abstract: A refrigerant mixture for a mixture throttle process contains from 0.06 mol/mol to 0.20 mol/mol propane, from 0.26 mol/mol to 0.36 mol/mol nitrogen and from 0.20 mol/mol to 0.38 mol/mol methane, the remainder being ethane.

Abstract: In a process for refrigeration in the 65 to 150 K temperature range, in which the refrigerant is compressed using an oil-lubricated compressor, then cooled to ambient temperature and then oil is removed from the refrigerant before the refrigerant is fed to a Joule Thomson heat exchanger, the refrigerant is additionally cooled after it has been cooled to ambient temperature and before it enters the Joule Thomson heat exchanger. In a device for refrigeration in the 65 to 150 K temperature range, which has an oil-lubricated compressor for compressing a refrigerant, an aftercooler connected downstream for cooling the refrigerant to ambient temperature, a device following on from this for removing oil from the refrigerant and a Joule Thomson countercurrent heat exchanger connected downstream of the device for removing the oil, an oil condenser is arranged between the aftercooler and the Joule Thomson countercurrent heat exchanger.

Abstract: A facility to process metal wastes is provided. The facility includes an inclined heat-insulated casing with a door and a cover, which can be displaced and removed. The inner surface of the casing is provided with removable sheets which form the inner facing (reflectors) of the casing and which are made of metal bead-formed sheets. Inside the casing, on a cantilever-supported shaft, is installed a melting drum, which can be mounted or removed from the shaft both charged and empty. The drum can be charged through the open cover when the casing door is open, while inside the casing it is kept installed on the shaft. A cross-shaped member for stiffening the drum is used also for mixing. The drum is heated via a burner and the heating is controlled with a temperature sensor and by means of an automatic control unit.
