Abstract: Methods for transporting a biologically active agent across a cellular membrane or a lipid bilayer. A first method includes the steps of: a) providing a biologically active agent which can exist in a native conformational state, a denatured conformational state, and an intermediate conformational state which is reversible to the native state an d which is conformationally between the native and denatured states; b) exposing the biologically active agent to a complexing perturbant to reversibly transform the biologically active agent to the intermediate state and to forth a transportable supramolecular complex; and c) exposing the membrane or bilayer to the supramolecular complex, to transport the biologically active agent across the membrane or bilayer. The perturbant has a molecular weight between about 150 and about 600 daltons, and contains at least one hydrophilic moiety and at least one hydrophobic moiety. The supramolecular complex comprises the perturbant non-covalently bound or completed with the biologically active agent. In the present invention, the biologically active agent does not form a microsphere after interacting with the perturbant. A method for preparing an orally administrable biologically active agent comprising steps (a) and (b) above is also provided as are oral delivery compositions. Additionally, mimetics and methods for preparing mimetics are contemplated.

Abstract: Magnesium fluoride slag contaminated with metallic uranium or uranium compounds is treated by digestion with potassium hydroxide to soluble potassium fluoride and insoluble magnesium hydroxide. The solid and liquid phases are then separated and the solids phase is dissolved in acid to form a solution of metal salts. The liquid phase is treated with lime to precipitate calcium fluoride and convert the potassium back to potassium hydroxide for recycle to the digestion reaction. The metal salts are separated to remove the uranium salt from the magnesium salt. The result is an efficient removal of uranium contamination from the magnesium, the recovery of magnesium in a manner that permits efficient reuse or safe disposal, and the production of calcium fluoride useful for a variety of purposes.

Abstract: Techniques employed in packet networks for transferring a packet across subnetworks with different namespaces. When a packet enters a given subnetwo rk and has a destination in a subnetwork with a different namespace, the given subnetwork encapsulates the packet by adding a header which specifies a decapsulator in the namespace. When the packet arrives at the decapsulator, the decapsulator strips the header and provides the packet to a subnetwork with a different namespace. A particular use of the technique is in a networ k used for broad-band interactive service. The network has two subnetworks. Th e first subnetwork is a TV channel which functions as a high-bandwidth forward  channel and the second subnetwork is a packet network accessible via a publi c modem pool which functions as a lower-bandwidth return channel. The encapsulator establishes a connection with the public modem pool and receive s an address in the second subnetwork which is temporarily associated with the  connection. When the encapsulator receives a packet which is produced in response to a packet received from the TV channel and has a destination address in the subnetwork of the TV channel, the encapsulator places a heade r on it which contains the temporary address and the address of the decapsulator. When the packet arrivesat the decapsulator, the decapsulator removes the header and provides the packet to the second subnetwork.
