Abstract: Fish sexual characteristics are determined by measuring the concentration in fish serum, plasma or whole blood of one or more peptide hormones of the transforming growth factor-beta superfamily (TGF-? superfamily). The disclosed method and an accompanying field test kit may be used in sturgeon aquaculture to cull out young male fish so that increased time and resources may be devoted to the further rearing of female fish for caviar production. The method and test kit may also be used for wild fish life history studies.

Abstract: A planar support assembly for use with a patient body support, an extension support assembly, and a plurality of interchangeable head supports is provided. The extension support assembly is releasably mounted on a portion of the patient body support such that the extension support assembly extends outwardly from the patient body support. The planar support assembly includes a generally planar support configured to releasably attach to an end of the extension support assembly opposite the patient body support. The planar support is configured to receive and support one of a plurality of interchangeable head supports, and the planar support is adjustable with respect to the patient body support in two or more dimensions.

Abstract: An arrangement used in safing and arming a munition device. The pressure sensor responds to pressure generated by igniting propellant of the munition and displaces from a first to second position. The power supply responds to setback of the munition to generate an electrical voltage. The light-emitting device responds to the electrical voltage. The photosensitive device connected to the power supply is powered by generation of the voltage and responds to receipt of light energy. An electro-explosive actuator connected to the photosensitive device is operable in response to electrical energy to actuate a rotor of the munition fuze from an unarmed condition to an armed condition. A fiber optic routing element defines a light transmission path from the light-emitting device to the photosensitive device via the pressure sensor.

Abstract: An arrangement used in safing and arming a munition fuze includes a light sensor, a magnet, and a circuit composed of an inductor coil, a storage capacitor, and a photosensitive device. The light sensor is a fiber optic cable which responds to a flash of light generated by burning propellant of the munition by receiving and guiding the light energy to the photosensitive device. The magnet responds to setback of a projectile of the munition to move relative to the coil and generate an electrical voltage. The photosensitive device connected to the inductor coil responds to the voltage generated and to receipt of light energy from the light sensor by conducting electrical energy. An electro-explosive actuator connected to the photosensitive device is operable in response to conducting of electrical energy to actuate a rotor of the munition fuze from an unarmed condition to an armed condition.

Abstract: A method of making a long rod penetrator having a rearward vane section which comprises forming the vane section by stamping a plurality of vanes from sheet metal and welding them to the rear portion of the penetrator.

Abstract: An electrical connector comprising first, second and third legs, said legs being arranged to permit said second leg to be spacially separated by force from said first and third legs thus, permitting an electrical conductor to be placed between the second leg and the first and third legs and permitting said electrical conductor to be retained by said legs.
