Abstract: The present invention provides a class of sensors prepared from regions of conducting organic materials and conducting materials that show an increase sensitivity detection limit for amines. The present class of sensors have applications in the detection of spoiled food products and in testing for diseases, such as cholera and lung cancer, which have amines as biomarkers.

Abstract: A spa filter cartridge cleaning apparatus configured to substantially remove contaminants from a spa filter cartridge. The cleaning apparatus further includes a container that has a plurality of walls configured to define an interior volume of sufficient size to receive a spa filter cartridge therein. A cleaning cylinder is disposed within the container and functions to be mateably connected with the hollow core of a spa filter cartridge. The cleaning cylinder further includes a plurality of apertures that function to discharge cleaning liquid disposed within the cleaning cylinder. An attachment mechanism operably connects the cleaning cylinder to a water source. A pinion gear is operably connected to one end of the cleaning cylinder and functions to rotate the cleaning cylinder for increased cleaning effectiveness of the spa filter cartridge secured thereto.

Abstract: The invention disclosed herein is a process for increasing the achievable concentration of a pharmaceutically active ingredient relative to fill composition viscosity for dosage units. The process is particularly useful in the preparation of soft gelatin capsules containing ibuprofen, naproxen, indomethacin, and acetaminophen, as the pharmaceutically active ingredient. As a result of the process, lesser quantities of composition ingredients other than the pharmaceutically active ingredient are needed to accomplish the same therapeutically effective dosage, thereby significantly increasing the concentration of the pharmaceutically active ingredient resulting in either a reduction in overall fill volume and dosage unit size or an increase in concentration of pharmaceutically active ingredient per dosage form.
