Abstract:
The present invention relates to an improved approach for the treatment of microbial infections in mammals. Specifically, the invention provides methods and reagents for expressing in mammalian cells, proteins having anti-microbial activity. The invention provides both genes, which have been modified to allow expression and preferably secretion of active protein in desired mammalian cells or tissues, and methods of introducing such modified genes into desired mammalian cells and/or tissues. Most specifically, genes encoding anti-staphylococcal proteins are delivered to mammalian cells and/or tissues by methods of gene delivery, including gene therapy and the production of transgenic animals, for the treatment of mastitis in ruminant animals.
Abstract:
A communication system may include a first control circuit to detect a break on a first optical link; a first optical source to supply a first optical signal on a second optical link in response to detecting the break on the first optical link, the first optical signal propagating in a first direction on the second optical link; a second control circuit to detect a presence of the first optical signal on the second optical link, and output a control signal in response to detecting the presence of the first optical signal; and a second optical source to supply a second optical signal on the second optical link, the second optical signal propagating in a second direction opposite the first direction, where the Raman pump is disabled in response to the control signal.

Abstract:
There is disclosed a transducer with an integral switch for wireless electronics. Essentially, the transducer contains a housing which includes a sensor device. The sensor device may be a piezoresistive Wheatstone bridge arranged in a conventional manner. The output of the bridge is coupled to a typical amplifying circuit or an analog-to-digital converter whose signal is coupled to a suitable transmitting means. The signal provided by the Wheatstone bridge is transmitted through RF, infrared or some other wireless transmission scheme to a remote location. Such transmissions schemes are well known. Associated with the sensor and secured to the sensor housing, is a push button switch which is wired in series with a battery. The battery operates to energize the sensor, including all the electronics when the sensor is in placed in a pressure sensing position. When the pressure is placed in a pressure sensing position, the push button switch, is actuated to apply operating bias to the transducer device.
Abstract:
A process for etching of silicon oxide such as silicon dioxide, or oxynitride. The process includes etching a silicon oxide layer to expose an underlying electrically conductive titanium silicide layer and provide a contact opening extending through the silicon oxide layer to the electrically conductive titanium silicide layer. The etching is performed by exposing the silicon oxide layer to an etching gas in an ionized state in a reaction chamber of a plasma generating device. The etching gas includes a fluoride-containing gas and a passivating nitrogen gas which is present in an amount effective to suppress a removal rate of the electrically conductive titanium silicide layer when it is exposed to the etching gas during the etching step. The fluoride-containing gas can be CF.sub.4, CHF.sub.3, C.sub.2 F.sub.6, CH.sub.2 F.sub.2, SF.sub.6, other Freons and mixtures thereof. The etching gas can also include a carrier gas such as Ar, He, Ne, Kr or mixtures thereof. The etching can be reactive ion etching or plasma etching and the etching gas can be exposed to a microwave electric field and/or a magnetic field during the etching step. The etching gas reduces the amount of the titanium silicide layer etched during overetching thereof compared to the same etching gas without nitrogen.
