Abstract: The invention relates to an improved process for providing purified styrenic monomers, such as styrene, from styrene-containing polymer waste. Styrene-containing waste is depolymerized in a suitable reactor, and the depolymerization products are condensed and separated in a three-step distillation process.

Abstract: In one embodiment, an electromagnetic (EM) energy containment device includes a spherically symmetric resonant dielectric structure having a radial dimension R0 defined as R0=3/?·?0/2 and having first and second regions with different indices of refraction. The spherically symmetric resonant dielectric structure is configured to receive and to contain, for a selectable duration of time, an electromagnetic wave of a wavelength ?0, and can find applications in delay circuits for beam steering for example.

Abstract: A method for securely processing data is provided. The method allows for processing data out of context to assure security and can use a combination of multiple encryptions, hashing techniques, homomorphic searching, two or more key owners and threat detection and response to further enhance the security of the data.

Abstract: A vaccine for in ovo vaccination against avian coccidiosis produced by a method including obtaining the coccidial oocysts from a fecal suspension, homogenizing the fecal suspension, separating the oocysts from the fecal debris by either salt flotation using sodium sulfate or gas flotation using air, sporulating the oocysts using hydrogen peroxide and air sparging, bleaching the sporulated oocysts, washing the bleached oocysts, concentrating the sterile washed oocysts and combining the concentrates of various species of coccidial oocysts, and producing a vaccine. The method in whole or in part can be applied to other kinds of encysted protozoa to produce vaccines for various types of animals.

Abstract: Novel methods of making laminated, microchannel devices are described. Examples include: assembly from thin strips rather than sheets; and hot isostatic pressing (HIPing) to form devices with a hermetically sealed wall. Laminated microchannel articles having novel features are also described. The invention includes processes conducted using any of the articles described.
