摘要:
The present invention pertains, at least in part, to novel 7-substituted tetracycline compounds. These tetracycline compounds can be used to treat numerous tetracycline compound-responsive states, such as bacterial infections and neoplasms, as well as other known applications for minocycline and tetracycline compounds in general, such as blocking tetracycline efflux and modulation of gene expression.
摘要:
The present invention relates to compounds useful as inhibitors of PI3K, particularly of PI3Kγ. The invention also provides pharmaceutically acceptable compositions comprising said compounds and methods of using the compositions in the treatment of various disease, conditions, or disorders.

The present invention pertains, at least in part, to novel 9-substituted minocycline compounds. These minocycline compounds can be used to treat numerous tetracycline compound-responsive states, such as bacterial infections and neoplasms, as well as other known applications for minocycline and tetracycline compounds in general, such as blocking tetracycline efflux and modulation of gene expression.
摘要:
An improved apparatus and method for providing reflux to a refluxed heavies removal column of a LNG facility. The system withdraws a fraction of a predominately methane refrigerant from a methane refrigeration cycle of the LNG facility. The withdrawn methane refrigerant is then cooled in an auxiliary heat exchange system by indirect heat exchange with a refrigerant that is also used to cool the natural gas feed stream upstream of the heavies removal column. The resulting cooled predominately methane steam is then employed as reflux to the heavies removal column.
摘要:
An improved apparatus and method for providing reflux to a refluxed heavies removal column of a LNG facility. The apparatus comprises stacked vertical core-in-kettle heat exchangers and an economizer disposed between the heat exchangers. The reflux stream originates from the methane-rich refrigerant of the methane refrigeration cycle. The liquid reflux stream generated by cooling the methane-rich stream in the vertical heat exchangers via indirect heat exchange with an upstream refrigerant.
摘要:
A motor controller includes a motor winding heater function. The motor controller applies a predefined current to one or more of the motor windings without the use of additional dedicated motor winding heater devices. The motor controller serves to control the operation of the motor, while the motor windings serve both as a heater at times and to produce torque at times.
