Abstract:
Disclosed are systems and methods for providing ring back tones in a communication network. At first, a ring back tone device for storing and playing the ring back tone customized by a subscriber is established in the communication network. Whether a subscriber is a ring back tone service register subscriber is judged with a certain triggering mode, such as intelligent network triggering, signaling interception triggering, call forwarding triggering or switching device triggering. If it is judged the subscriber is a ring back tone service registered subscriber, a connection between the originating switching device and the terminating switching device and a connection between a switching device and the ring back tone device are established. When the called terminal is idle, the ring back tone device provides a piece of customized ring back tone to the calling subscriber for replacing traditional ring back tone.
Abstract:
A liquid crystal diffractive light valve includes: a pair of opposed substrates wherein one of the substrates is a silicon wafer with associated electronics. The other substrate has an electrode layer facing the silicon substrate. And a ultraviolet curable composite material is disposed between the substrates which is then phase separated to form polymer walls having liquid crystal directors fixed therein regardless of application of an electric field across the electrode layers, and wherein pixel regions are formed between the polymer walls. The pixel regions have liquid crystal directors which are movable when an electric field is applied across the electrode layers. Application of an electric field allows for generation of phase differences between the wall and pixel regions to allow for Liquid Crystal on Silicon devices to be used as diffractive light valves.
Abstract:
Methods of inducing mucosal immunity in individuals against proteins and peptides are disclosed. The methods comprise the step of administering topically or by lavage into mucosal tissue selected from the group consisting of rectal, vaginal, urethral, sublingual and buccal, a nucleic acid molecule that comprises a nucleotide sequence that encodes a protein or peptide that comprises an epitope against which mucosal immunity is desired. The methods may be used to immunize an individual against a pathogen infection, hyperproliferative diseases or autoimmune diseases using nucleic acid molecules which encode proteins and peptides that share an epitope with a pathogen antigen or protein associated with cells involved in hyperproliferative diseases or autoimmune diseases, respectively.
Abstract:
The invention relates to specific bacterium and proteins with xylanase activity derived from the bacteria, in particular to xylanases which are free of any significant cellulase activity and which are active at high temperature and at neutral to alkaline pH. Xylanases having these characteristics are particularly useful in the bleaching of wood pulps, such as kraft pulps. The preferred bacterium designated B230 was isolated from white-rotted kerri wood in Western Australia; a sample of which has been deposited under the provision of the Budapest Treaty in the Australian Government Analytical Laboratories under the accession number N94/41262. This preferred bacterium is a gram positive, obligatively aerobic, rod-shaped with a centrally-located spore and has the taxomonic characteristics of Bacillus subtilis (by VITEK method).
Abstract:
Methods of introducing genetic material into cells of an individual and compositions and kits for practicing the same are disclosed. The methods comprise the steps of contacting cells of an individual with a genetic vaccine facilitator and administering to the cells a nucleic acid molecule that is free of retroviral particles. The nucleic acid molecule comprises a nucleotide sequence that encodes a protein that comprises at least one epitope that is identical or substantially similar to an epitope of a pathogen antigen or an antigen associated with a hyperproliferative or autoimmune disease, a protein otherwise missing from the individual due to a missing, non-functional or partially functioning gene, or a protein that produces a therapeutic effect on an individual. Methods of prophylactically and therapeutically immunizing an individual against HIV are disclosed. Pharmaceutical compositions and kits for practicing methods of the present invention are disclosed.
Abstract:
The present invention provides a electric generator with novel structure, comprising two parts: a stator and a rotor. The stator has rectangle-section winding slots. The stator teeth have sectorial section. Slits are formed extending axially in the yoke and the magnet poles laid on the yoke in the rotor. The stator windings are made up of square-wave open rings with different pitches. The generator of the present invention has much less weight and smaller size, and the manufacturing process is simple, the consuming of copper and silicon steel sheets can be reduced, the efficiency is higher and energy can be saved.
