    Abstract: Provided is a method for preparing a true, homogeneous solution of a pharmaceutical substance dissolved in an organic solvent in which the pharmaceutical substance is not normally soluble. Solubilization is obtained by forming a hydrophobic ion pair complex involving the pharmaceutical substance and an amphiphilic material. The resulting organic solution may be further processed to prepare pharmaceutical powders. A biodegradable polymer may be co-dissolved with the pharmaceutical substance and the amphiphilic material and may be incorporated into a pharmaceutical powder. A preferred method for preparing pharmaceutical powders is to subject the organic solution to gas antisolvent precipitation using a supercritical gas antisolvent such as carbon dioxide. Also provided is a method for making hollow particles having a fiber-like shape which would provide enhanced retention time in the stomach if ingested by a human or animal host. Further provided are novel biocompatible cationic surfactants and uses therefor, including the delivery, in vitro and in vivo, of nucleic acids into cells to transform the cells.

    Abstract: A condenser system for controlling vapor concentration contained in a flowing airstream is provided. The flowing airstream has an initial temperature upon entering the condenser system and a final temperature upon exiting the condenser system. The condenser system has a membrane member allowing mass transfer of the vapor therethrough with the airstream contacting the membrane member. A condensing member diffuses the vapor from the airstream through the membrane member. An insulating layer is positioned between the membrane member and the condensing member with the insulating layer inhibiting heat transfer between the flowing airstream and the condensing member wherein the final temperature of the airstream is substantially equal to the initial temperature of the airstream.

    Abstract: This invention provides a method and apparatus for analyzing the propagation of optical fields between arbitrarily oriented planes using full scalar diffraction theory. One aspect of the invention allows propagation between tilted planes. A second aspect allows propagation between offset planes. To analyze the propagation of an input optical field from a first plane to a second plane, the input field in the spatial domain is Fourier transformed to obtain the plane wave distribution in the spatial frequency domain. Within the spatial frequency domain the field is propagated from the first plane to the second plane by first multiplying the plane wave distribution by the spatial frequency domain phase accumulation between the first and second planes, and then converting the plane wave distribution from the coordinate system of the first plane to that of the second plane. Finally, the propagated plane wave distribution is inverse Fourier transformed to obtain the propagated optical field. This propagation sequence forms the building block for a numerical method to analyze optical systems using full scalar diffraction theory. To analyze optical systems, the input field is propagated from the plane of the source to the plane of the first optical element and the propagated optical field is multiplied by the transmittance function of the optical element. This invention further includes tolerance analysis of each parameter that affects the image quality and coupling efficiency of the optical system.
