Abstract: A barrel assembly for a device for shooting projectiles is disclosed. The barrel assembly comprises a firing chamber with first and second openings, wherein the firing chamber is capable of holding at least two projectiles. A first projectile retention device is located at the second opening of the firing chamber. A propellant injection device injects propellant into the firing chamber through a third opening. A firing control device initiates the injection of propellant into the firing chamber, wherein at least one projectile and the projectile retention device substantially seal the second opening of the firing chamber when propellant is introduced and at least one projectile is expelled out of a barrel through the first opening of the firing chamber.

Abstract: The present invention is directed to a method of isolating and culturing spiroplasma by obtaining a tissue sample from a bovine; inoculating embryonated eggs with the tissue sample; mixing fluid from the inoculated egg with culture media; culturing the media mixed with the egg fluid at approximately 32° C. for preferably greater than a month to establish a spiroplasma culture.

Abstract: The invention provides a method for generating transgenic animals and cells by the coinsertion of nucleic acid and a nucleus into an unfertilized oocyte. Preferably, the coinsertion is by microinjection and more preferably by piezo-electrically actuated microinjection. Transgene (tg) expressing embryos are here produced following coinjection of unfertilized mouse oocytes with sperm heads and exogenous DNA encoding either a green fluorescent protein (GFP) or ?-galactosidase reporter. The microinjected oocyte may be allowed to develop into differentiated cells or stem cells; into an embryo in vitro prior to transfer into a host surrogate mother, or it may be transferred directly into a host surrogate mother. Embryonic development can occur to term, such that the offspring possess transgenic modifications that may alter their characteristics (phenotype) and are, in turn, transmitted to their offspring.

Abstract: A method of modulating an infrared radiation (IR) source that includes applying a time-varying, periodic voltage signal to the IR source, measuring a parameter of the voltage signal, and adjusting the voltage signal to maintain a substantially constant delivered power to the IR source. Adjusting the voltage signal is done based on the measured parameter and a predetermined relationship between the measured parameter of the voltage pulse and a resistance of such an infrared radiation source. Alternatively, the method includes applying a the voltage pulse, measuring a first parameter of the voltage pulse and a second parameter of a current passing through the infrared radiation source resulting from the applying step, and adjusting the voltage pulse to maintain a substantially constant delivered power to the infrared radiation source based on the first parameter and the second parameter.

Abstract: The present invention provides methods of preparing mammalian cells and tissues for therapeutic and diagnostic purposes that are derived from ntES cells. The present invention further provides the mammalian cells and tissues themselves. In addition, methods of using the mammalian cells and tissues as a therapeutic agent or as a diagnostic are provided.
