Abstract: The invention relates to acaricidal compositions for the control of ectoparasites of domesticated, warm blooded animals. Methods for application of the composition disclosed are also taught.

Abstract: Novel dihydroisoxazole compounds are disclosed having activity against parasitic worms and showing little or no toxicity to the host animal. These compounds are 3-chloro-4-dialkylaminophthaloylamino-4,5-dihydroisoxazoles and 3-dialkylamino-4-dialkylaminophthaloylamino-4,5-dihydroisoxazoles. A process for making these compounds and a method of administering them to infested animals is also disclosed.

Abstract: Monorden is administered to animals to increase fertility by inducing multiple births, promoting estrus synchronization, increasing litter sizes, and increasing conception rates.

Abstract: A device for the release of a diffusible solid in a fluid medium which comprises a disc which comprises a substantially uniform mixture of said diffusible solid and a polymer which is insoluble in and impermeable to said fluid medium and impermeable to said diffusible solid. The surfaces of said disc are coated with a polymer which is insoluble in and impermeable to said fluid medium and impermeable to said diffusible solid, with the exception of one or more apertures which extend through the disc and expose a portion of the mixture of diffusible solid and polymer to the fluid medium when the device is immersed therein. The aperture or apertures are placed in said disc such that as said fluid medium enters the disc through said aperture or apertures, the ratio of surfce area of diffusible solid exposed to the fluid medium to the length of the path through which the exposed solid must diffuse to exit the disc remains substantially constant.

Abstract: An improved process is described for recovering proteins from insoluble inclusion bodies produced in transformant microorganisms. Sidestream precipitates isolated from chromatography effluent are resolubilized in a denaturing agent and the resolubilized proteins are renatured either by direct dialysis into denaturant-free buffer or by dialysis into a weaker denaturing agent followed by dialysis into denaturant-free buffer.

Abstract: A TUNNETT (tunneling transit time) electronic device comprising a very thin injector uniformly doped at a high concentration, a thin drift region of lower doping of the same semiconductivity type, and a collector of high doping of the same semiconductivity type. A Schottky barrier is formed by placing a metal electrode on the injector and an ohmic contact may be made on the collector. In a preferred embodiment the injector is made of Ge grown on the drift region by vacuum epitaxy. The drift region is preferably GaAs grown by epitaxy on a GaAs collector.
