Abstract: A capacitive sensor system configured to measure capacitance, including a sample volume, a sample capacitive sensor configured to measure the capacitance of the sample volume without physical contact between the sample capacitive sensor and the sample volume, a control capacitive sensor, a differential sensing subsystem configured to measure a control sensor volume using the control capacitive sensor, and electrical circuitry connected to both the control capacitive sensor and the sample capacitive sensor.

Abstract: The current disclosure provides compositions, systems, and methods for detection and/or identification of antibodies. Also provided are compositions, systems, and methods that expedite and simplify processes to identify blood units that are clinically appropriate for transfusion into a recipient, and more generally to identify the presence of antibody(s) in blood that are specific for selected antigen(s). The systems and methods utilize genetically-modified (transgenic) non-target-organism red blood cells that express at least one antigen of the target organism species. This enables screening and identifying blood units faster, more consistently, at large scale, and/or with less dependence on human involvement.

Abstract: The present invention relates to the use of a lubricant in a diesel engine equipped with a regenerable diesel particulate trap, wherein the lubricant comprises a base oil component having a paraffin content of greater than 80 wt % paraffins, a saturates content of greater than 98 wt %, and comprising a series of iso-paraffins having n, n+1, n+2, n+3 and n+4 carbon atoms, wherein n is between 15 and 40, and to a process for operating a diesel engine equipped with a diesel particulate trap, comprising lubricating the diesel engine with the lubricant.
