摘要:
Human CDKL1 genes are identified as modulators of branching morphogenesis, and thus are therapeutic targets for disorders associated with defective branching morphogenesis function. Methods for identifying modulators of branching morphogenesis, comprising screening for agents that modulate the activity of CDKL1 are provided.
摘要:
The present invention is an apparatus for simulating corrosion activity in liquid and vapor/condensate corrosion environments. The apparatus includes a container, including a lower region containing the liquid and an upper region, including a condenser, a heater for providing heat to the lower region such that the liquid is maintained at a given temperature, a vacuum pump for providing a partial vacuum at a given pressure in the upper region of the container, one corrosion probe removably positioned in the liquid, and a second corrosion probe removably positioned above the liquid.

The present invention relates to a method for inhibiting high temperature corrosion of corrosion prone metal surfaces by organic acid-containing petroleum streams by providing an effective corrosion-inhibiting amount of an additive aromatic compound tri-substituted with acidic functionalities selected from 5-hydroxyisophthalic acid and 1,3,5-benzenetricarboxylic acid, typically up to 1000 wppm, to the metal surface.
摘要:
A rotordynamic machine for the forwarding of a fluid, such as a turbomachine (2) or a centrifugal pump, has at least one drive and bearing apparatus (1) which is designed as an electrical machine with a stator and with a magnetically journalled rotor (4a). Electrical windings (15, 16) produce the required torque and the magnetic bearing force and are arranged together in the stator. The rotor (4a) forms a section of the shaft (4) of the turbomachine (2) and a control apparatus (7) and excites the two windings (15, 16). A magnetic suspension force acting on the rotor (4a) is produced with the first winding (16) in order to hold the shaft (4) in the radial direction without contact. The torque acting on the rotor (4a) is produced with the second winding (15).
摘要:
The invention relates to a nitrilase having improved activity in the reaction of a nitrile to form the corresponding carboxylic acid, in particular with respect to reacting 2-methylglutaronitrile, 1-(cyanomethyl)cyclohexane-1-carbonitrile, and benzonitrile. The nitrilase according to the invention is related to nitrilase from acidovorax facilis.
摘要:
In an embodiment, a method of providing a personalized display of data is presented. In this method, an identity of each of multiple applications for displaying data is transmitted to a user device, such as, for example, a computer or mobile communication device. Selections of more than one of the multiple applications are received from the user device. Configuration data indicating the selected applications are generated and stored. A request for a presentation application is received from the user device. The presentation application is to display the data via execution of the selected applications. In response to the request, the presentation application is generated based on the configuration data, and includes the selected applications. The presentation application is then transmitted to the user device for execution.
摘要:
A method and a system for measuring market data in a mobile communications system. The method and system may be used to obtain data such as growth, churn rate, and other measurable metrics of mobile communications device subscribers. The method includes selecting a sample of contact numbers, using one or more contacting or querying methodologies to assess the state of the contact numbers, and analyzing the results to determine the market data.
