    摘要： A carbon monoxide sensor and method is shown and described. The sensor includes a sensing element that includes an adsorbent dispersed over a support material. The adsorbent is capable of exothermically adsorbing carbon monoxide. The sensor also includes a temperature sensor in contact with the sensing element and a signal processing module coupled to the temperature sensor. The temperature sensor communicates signals indicative of a temperature increase of the sensing element to the processing module, thereby indicating an adsorption and, therefore, a presence of carbon monoxide.

    摘要： Methods and compositions are provided for detecting HLA polymorphs where distinguishing antibodies are not readily available. Cross-reactive antibodies are employed, where one cross-reacts with the HLA of interest and other alleles, and the other cross-reacts with one of the other alleles, but not with the HLA of interest. By appropriate protocols and controls, the polymorph of interest may be detected.

    摘要： The remote temperature measurement of a fluid is determined by Raman backscattered radiation from the fluid where the fluid is subjected to intense pulses of laser radiation generated at a remote location. The backscattered radiation is filtered to selectively attenuate reflected radiation from the laser and is transmitted to a detector system which individually counts the detected radiation in each of two different radiated frequencies. A divider generates a ratio of the count which is transformed by a function generator to produce an output signal indicative of fluid temperature.
