Abstract: A vehicle jacking assembly for selectively raising a wheel of a vehicle for changing a tire includes a plurality of cylinders and an actuator. Each cylinder is configured to be coupled to a frame of a vehicle proximate to a respective wheel of the vehicle. The cylinder comprises a plurality of nested sections so that the cylinder is selectively extensible. The actuator is configured to be coupled to the vehicle and to be operationally coupled to an electrical circuit of the vehicle. The actuator is operationally coupled to the plurality of cylinders so that the actuator is positioned to selectively actuate a respective cylinder to extend the respective cylinder from the frame of the vehicle so that the respective cylinder contacts a surface. The respective cylinder thus is configured to raise an associated wheel of the vehicle from the surface, allowing a tire of the wheel to be changed.

Abstract: A radioactive thermogel suspension, including a thermogel and a plurality of insoluble radioactive isotope phosphate particles, such as yttrium phosphate, suspended in the thermogel. The thermogel is PLGA-g-PEG. The thermogel contains less than 65 ppm stannous octanoate. The plurality of radioactive yttrium phosphate particles are between 0.03 µm and 10 µm in diameter. The plurality of radioactive yttrium phosphate particles are generally spherical. The YPO4 particle concentration is in the range of 3 mg/ml to 100 mg/ml.

Abstract: The method of the present invention provides an improvement upon prior art methanol carbonylation methods which substantially reduces the production of carbonyl impurities. The production of carbonyl impurities, particularly acetaldehyde, crotonaldehyde, and 2-ethyl crotonaldehyde, in methanol carbonylation reactions has been found to decrease by maintaining less than about 4.5 wt % methyl iodide in the reaction medium during the course of the reaction.
