Aerosol particle analyzer (APA) for measuring an analyte in airborne particle is described. Airborne particles are first given an electrical charge and then drawn in air past an oppositely charged volume of an analysis liquid that exposed to the air at a small hole in a container, such as a capillary, that holds that analysis liquid. Electrostatic forces enhance the rate that the airborne particles collide with the small exposed volume of the analysis liquid in the hole. If the particles that collide with the analysis liquid contain the analyte, an optical property of the analysis liquid, such as the fluorescence, varies according to the amount of the analyte in the particles. This optical property is measured and the amount of analyte in the particles is determined from the measured optical property.

An approach that optimizes system performance using performance monitors is presented. The system gathers thread performance data using performance monitors for threads running on either a first ISA processor or a second ISA processor. Multiple first processors and multiple second processors may be included in a single computer system. The first processors and second processors can each access data stored in a common shared memory. The gathered thread performance data is analyzed to determine whether the corresponding thread needs additional CPU time in order to optimize system performance. If additional CPU time is needed, the amount of CPU time that the thread receives is altered (increased) so that the thread receives the additional time when it is scheduled by the scheduler. In one embodiment, the increased CPU time is accomplished by altering a priority value that corresponds to the thread.

A process is provided for selectively removing protein aggregates from a protein solution in a normal flow (NFF) filtration process. Preferably, it relates to a process for selectively removing protein aggregates from a protein solution in a normal flow (NFF) filtration process and virus particles from a protein solution in a two-step filtration process. In a first step, a protein solution is filtered through one or more layers of adsorptive depth filters, charged or surface modified microporous membranes or a small bed of chromatography media in a normal flow filtration mode of operation, to produce a protein aggregate free stream. The aggregate free protein stream can then be filtered through one or more ultrafiltration membranes to retain virus particles at a retention level of at least 3 LRV and to allow passage therethrough of an aggregate free and virus free protein solution.

In accordance with the present invention, an x-ray diffraction apparatus and method are provided in which an x-ray or goniometer head can be adjusted in different directions to allow the head to direct x-rays at a part from various positions. In this manner, measurements can be taken from a wider region of the part without requiring that the part itself be moved or that an operator move the unit, which can be relatively heavy. In one aspect, the head can be rotated about its internal axis so that it can more readily direct x-rays along curved surfaces of parts while keeping a substantially constant distance therefrom. It is preferred that the apparatus be a portable unit including adjustment mounts to allow the x-ray head to be moved in the different directions so that it can be transported for use in the field at the site at which a part is located. In this instance, the unit allows for measurements to be taken from the part while it remains in service. Accordingly, the present portable unit allows for x-ray diffraction techniques to be used on parts where it is not practical or economic to remove them from service, such as cables or wire ropes used as tension members for bridges. Moreover, the preferred portable x-ray diffraction unit herein provides an easy to interpret readout of the results of its measurements by generating a map at the part site so that, for example, any abnormalities in stress measurements taken will be highlighted in comparison to adjacent points on the map where more normal measurements are shown.
