Title: Method of production of astaxanthin by fermentation of selected strains of xanthophyllomyces dendrorhous
Inventor: DE LA FUENTE MORENO JUAN LUIS
IPC: A23L1/28
Filed: 2003-02-03
Abstract: The invention relates to methods of (i) obtaining astaxanthin-overexpressing strains of X. dendrorhous and (ii) using said strains under improved fermentation conditions. The methods of selecting the strains used are based on: (i) resistance to steroid synthesis inhibitors, respiration inhibitors a nd compounds that induce the formation of free radicals; (ii) colour intensity of the colony and production of carotenoids in a solid medium; (iii) production of astaxanthin in darkness; (iv) production of astaxanthin at high temperatures; and (v) production of astaxanthin with carbon sources other th an glucose. The inventive methods can be used effectively to select mutants of X. dendrorhous with greater production of astaxanthin than the parent strain an d low accumulation of other carotenoids. The liquid medium culture of X. dendrorhous can be used to obtain a biomass that can be used directly in hum an and animal food.

Title: Congestion control in an ip network
Inventor: IBEZIM JAMES A
IPC: H04L69/40
Filed: 2004-09-30
Abstract: Upon detection of an overload condition at a network element, the network element sends two messages to those other network elements which may potentially send request messages to the overloaded network element. If the network utilizes the SIP signaling protocol, then the messages sent by an overloaded network element are SIP INVITE and SIP CANCEL. The CANCEL message comprises an indication that the sending network element is unavailable and an amount of time which the recipient network elements are to wait before sending any requests to the overloaded network node. Upon receipt of these messages, the receiving network elements wait for a delay time period before sending any additional request messages to the overloaded network element. During the waiting period, the waiting network elements may send request messages to network elements other than the overloaded network element which provide functionality similar to that of the overloaded network element.

Abstract: In the blade structure in a gas turbine, inlet included angles are made large. As a result, a curve of a relative relationship between incidence angles ic1 and is1 and pressure loss becomes mild. Entrance metal angles, which are formed by an axial direction of the gas turbine and a tangential direction to a camber line at the front edge of the stationary blade, are made small. As a result, it becomes possible to make the incidence angles small.      Chord length of a tip portion of a moving blade is made large. As a result, it becomes possible to make small the deceleration on a rear surface of the tip portion of the moving blade. Accordingly, it becomes possible to make the pressure loss small, and therefore, it becomes possible to improve the turbine efficiency.
