Abstract: The present invention provides a fermentation process for improving the production level of a recombinant human collagen. The process comprises inoculating a sterilized fermentation medium with a Pichia yeast solution, then performing fermentation culturing for 14-18 hrs, adding methanol to induce the expression, upon which sodium pyruvate is added to the fermentation medium, wherein the amount of the sodium pyruvate added is 0.01-10 g/L. In the fermentation process of the present invention, the sodium pyruvate is added in the methanol-induced expression stage, so that the biosynthesis rate of the recombinant human collagen is improved; and a continuous feed-batch mode is adopted, so that the biosynthesis rate of the recombinant human collagen is further improved, and the fermentation time is shortened. Meanwhile, the expression level of the recombinant human collagen is increased, the fermentation level is increased by more than 20%, and the production cost is reduced.

The first re-sputtering includes bombarding the metal compound and a dielectric layer on the conductive layer by inert ions and metal atoms. Then, a barrier is formed on the dielectric layer and the conductive layer. Later, a bottom of the barrier is removed. Subsequently, a metal layer is formed to cover the barrier.

Abstract: Herein provided are methods and systems for detecting failure of a sensor in a control system for a gas turbine engine. A signal is received from the sensor. A high-pass filter is applied to the signal to produce a high-frequency component signal. A rate of occurrence of signal spikes in the high-frequency component signal is determined. The high-frequency component signal is compared to a component signal threshold which is based on at least one known healthy component signal and at least one faulty component signal. The presence of intermittent open circuits caused by the sensor is detected based on the comparing and on the rate of occurrence of signal spikes.

Abstract: This invention generally relates to interference mitigation, and more specifically to interference mitigation in wireless communications networks. The proposed solution takes advantage of the clear channel assessment (CCA) function used by WLAN networks. Hence, by jamming the interfering WLAN channel during a predetermined time period, the interfering WLAN network is forced to withhold transmissions on the WLAN interfering channel during a backoff period of time. The solution of the subject application makes use of this backoff period to enable a WPAN network to transmit critical information such as, but not limited to, a request for changing the current working frequency.
