Abstract: A system for providing secure data storage, data transfer, and communication, the system communicably coupled with a global communications network, comprises a data repository configured for accessing an external overlay network consisting of a network of volunteer nodes that utilize onion routing to send and receive data, wherein the data repository is further configured for storing data and applications belonging to users, a database management system configured for: 1) accessing the overlay network; 2) controlling user access to the data repository via the overlay network, and 3) sending and receiving data via the overlay network using onion routing, and a client application configured for: 1) controlling user access to the client application by requiring security credentials; 2) accessing the overlay network over the global communications network, and 3) sending and receiving data via the overlay network using onion routing.

Abstract: One method for making a laminate material comprising a first surface layer comprising resorcinol arylate polyester chain members and a second surface layer suitable for bonding to a substrate, comprises co-extruding a polymeric first surface layer material and a polymeric second surface layer material through a die and into the first nip of a calender roll stack comprising a first surface roll and a second surface roll that define the first nip, to form the laminate material. A nip load in the first nip of greater than or equal to about 400 N/cm can be applied to the laminate, and the laminate material can be collected from the roll stack. The first roll and the second roll can each have a surface smoothness of less than or equal to about 5 micrometers and temperatures of about 40° C. to about 150° C.

Abstract: Certain polyethyleneimines are used to coat solid carriers used in immunoassays to improve the sensitivity of the assay over what is obtained without the coating. Use of the invention in enzyme immunoassays yields sensitivities equal to that of radioimmunoassays. A post-coating is also used after the solid carrier has had a layer of capture molecule applied and before the assay is performed, to improve even further the sensitivity, reliability and dynamic range of the assay results.

Abstract: There is disclosed a package comprising a rack and a surrounding cover therefor. The rack has a top surface which slopes downwardly from front to rear. This top surface has a plurality of recesses or wells into which small receptacles may be inserted and thereby supported in the rack. The said receptacles are sufficiently large so that they visibly protrude from the rack. As a result of this protrusion of the receptacles the cover has a hood-like configuration to make allowance therefor. The rack also has a rearwardly positioned slot means to receive and support a diagnostic plate and a forwardly positioned trough to hold a tube member.
