    摘要: The present invention relates to a method and system for using microwave radiation to detect contraband hidden inside of a non-metallic container, such as a pneumatic vehicle tire. The method relies on the attenuation, retardation, time delay, or phase shift of microwave radiation as it passes through the container plus the contraband. The method is non-invasive, non-destructive, low power, and does not require physical contact with the container.

    摘要: Host cells transfected with a recombinant DNA molecule which includes a DNA sequence inserted therein encoding a heterologous chicken BFIV MHC class I protein are disclosed. The transfected cells express the heterologous BFIV protein and may be used as an immunogen to produce chicken MHC class I (BFIV) specific antisera. The antisera so produced may then be used to determine the BF haplotype of any chicken.

    摘要: A magnetically insulated transmission line oscillator employs self-generated magnetic fields to generate microwave energy. An anode of the oscillator includes slow-wave structures which are formed of a plurality of thin conductive vanes defining cavities therebetween, and a gap is formed between the anode and a cathode of the oscillator. In response to a pulsed voltage applied to the anode and cathode, self-generated magnetic fields arfe produced in a cross-field orientation with respect to the orientation of the electric field between the anode and the cathode. The cross-field magnetic fields insulate the flow of electrons in the gap and confine the flow of electrons within the gap.

    摘要: Disclosed herein are cultures of undifferentiated avian primordial germ cells/blastodermal cells. The cultures are capable of maintaining their undifferentiated characteristic and also their capability of expressing the EMA-1 epitope for extended periods when cultured in the presence of an isolate from avian navel (e.g. turkey navel extract). Methods of culturing such cultures using avian navel extracts, and culture media containing avian navel extract are also disclosed. Recombinant birds derived from these cultures are also disclosed. These cultures can be frozen for long-term preservation of germ line genomes.
