    Abstract: An outer layer material having an entanglement comprising an intermingling of cloaked hydrophilic guest and a hydrophobic polymer host, wherein molecules of the guest have been crosslinked with each other. Under certain circumstances, using complexes of the guest may be desirable or even necessary. Prior to intermingling with the guest, a host blend may be produced to include a physical blend of a hydrophobic polymer host and a maleated hydrophobic co-host (preferably, an anhydride functionalized hydrophobic polymer, whereby the polymer so functionalized, is the same as that selected for the host). The intermingling of the guest and host, or host-co-host blend, includes a physical tangling, whether it also comprises crosslinking by primary bonding (e.g., chemical/covalent bonding) there-between. Also a method of producing an outer layer material having such an entanglement, including the steps of: temporarily cloaking at least a portion of the hydrophilic groups of the guest; intermingling at least a portion of the cloaked groups with a porous polymeric structure by diffusing the guest with cloaked groups into at least a portion of the structure's pores; within the pores, crosslinking at least a portion of the molecules of the guest with the guest; and removing the cloaking. Cloaking may be performed by silylation or acylation. Intermingling may be performed by producing a mixture of guest and host, or host blend, (whether in solution, powdered, granular, etc., form); next, a crosslinking of the guest with itself is performed; then, the mixture is molded into the outer layer with or without additional crosslinking of the host to the host.

    Abstract: The present invention proposes a method for doubly backing up files asynchronously, wherein at least two first network elements share a second network element, both of said first network elements include respectively an active file handling device and a standby file handling device, characterized in that, said active file handling device copies the files to the second network element, if said standby file handling device finds that said active file handling device misses the files, said standby file handling device copies backups of the files to said active file handling device, thus the files stored in said active file handling device and the files stored in said standby file handling device being synchronized.

    Abstract: A series of novel, melt- or mold-processable HA esters with varying aliphatic chain lengths are synthesized from silyl HA-quaternary (quat.) ammonium salt complex (preferably silyl HA-CTA, a silylated HA complex with cetyltrimethyl ammonium salt). Introduction of aliphatic acyl groups, preferably acid chlorides, to disrupt the strong HA intermolecular bonding, is done via acylation. Acylation takes place at the oxygen of the trimethylsilyloxy group -0-Si(CH 3 ) 3 in the silyl HA-CTA by removal of trimethylsilyl. groups therefrom. Optionally, crosslinking may be performed during the shaping/molding of the HA esters into a structure/device, or thereafter, if at all. Native HA can then be regenerated/recovered by saponification/ hydrolysis, removing acyl groups, -CH 3 (CH 2 ) 10 CO, and the cetyltrimethyl ammonium salt groups, -CTA, from HA ester. The structure/device of a preselected shape (e.g., porous or solid, bulk structure or fibers) may become a component of an assembly, a product that is further processed, integrated into another component (e.g., laminated, adhered, assembled, further shaped, chemically-intermixed/intermingled), and so on.
