A method of making a diatomaceous earth granulate may include spray-drying a suspension including particles of diatomaceous earth, a liquid medium, and a binder, wherein inorganic solids in the suspension include at least 80 wt % diatomaceous earth. The method may further include recovering a diatomaceous earth spray-dried granulate. A granular diatomaceous earth product obtained by the method may include substantially spherical granules, each having a shell including diatomaceous earth surrounding a hollow core. The product may be used as a filter aid or in filtration.

Provided is a method of increasing 3,4,5,6-tetrakisphosphate by increasing the activity of inositol 1,3,4,5,6 pentakisphosphate 1-phosphatase, and a method of decreasing 3,4,5,6-tetrakisphosphate by decreasing the activity of inositol 1,3,4,5,6 pentakisphosphate 1-phosphatase. A method of reducing salt, fluid or mucous secretion in a subject, comprising increasing the activity of inositol 1,3,4,5,6 pentakisphosphate 1-phosphatase in the subject is provided. A method of treating a disease that is exacerbated by salt, fluid or mucous secretion is also provided, comprising increasing the activity of inositol 1,3,4,5,6 pentakisphosphate phosphatase in a subject having a disease that is exacerbated by mucous, whereby mucous secretion is reduced and the disease is treated. Also provided is method of increasing salt and fluid secretion in a subject, comprising decreasing the activity of inositol 1,3,4,5,6 pentakisphosphate 1-phosphatase in the subject. A method of treating a disease that is treated by increased salt and fluid secretion is provided, comprising decreasing the activity of inositol 1,3,4,5,6 pentakisphosphate 1-phosphatase in a subject having a disease that is treated by increased salt and fluid secretion, whereby salt and fluid secretion is increased and the disease is treated.

Methods and apparatus for securing a cylinder liner to a pump module. A tension body is disposed about the cylinder liner and attached to the pump module. A locking body engages the cylinder liner and is threaded to the tension body. A hydraulic load cell is removably attached to the tension body and includes a hydraulic ram arranged to impart a compressive load to the cylinder liner and a tension load in the tension body. The locking body can be adjusted axially to contact the cylinder liner and maintain the applied loads, which act as a pre-load to keep the cylinder liner in contact with the pump module.

Oligomers having phosphonate internucleosidyl linkages which are enriched for phosphonate linkages of a preselected chirality which hybridize to an RNA target sequence and methods for their preparation are provided.
摘要:
Apparatus and method for applying radial compressive stress pre-loading to a cylinder liner. A cylinder housing is attached to a pump, and a cylinder liner is disposed within the cylinder housing. A fluid inlet in fluid communication with the annular space between the cylinder housing and cylinder liner is disposed on the cylinder housing. The annular space is filled with pressurizing fluid through the fluid inlet, which creates radial compressive stress pre-loading on the cylinder liner.
摘要:
Methods for purifying an oligomer by normal phase column chromatography on a support selected from polyhydroxyethyl aspartamide, hydrophilic silica and silica from an oligomer impurity having a different nucleoside sequence are described. These methods are based upon the different retention times of the oligomer and the impurity on the column.

Systems and methods to manage aircraft dispatch information are provided. A particular method includes receiving fault information at a dispatch information computing system. The fault information is associated with an aircraft. The method also includes accessing operational restriction information associated with the aircraft based on the fault information. The method further includes automatically determining a set of bottom line operational limitations of the aircraft based on the fault information and the operational restriction information. The method also includes generating customized checklists for the various users of the information. The method also includes sending output data from the dispatch information computing system to an output device. The output data identifies the set of bottom line operational limitations of the aircraft and tasks to be completed by the various users.

摘要:
Disclosed herein is a rubber composition comprising a rubber and particulate kaolin clay as a filler wherein: the kaolin particles have a particle size distribution such that at least about 95% of the particles, relative to the volume of the particles, have a particle diameter less than 3 μm. The particulate kaolin particles may comprise calcined kaolin chosen from at least one of particulate soak calcined kaolin and particulate flash calcined kaolin. The rubber composition can comprise additional particulate fillers including those chosen from silica, carbon black, and other particulate fillers. Also disclosed herein is a process for producing such a composition, and the method of using a cured form of the composition in a rubber composition, such as a vehicle tire composition.
摘要:
A method, system, and apparatus, for providing audio feedback regarding the operation of an aircraft. In one aspect, microphones are placed next to sound sources, which could be components of the aircraft. Audio inputs are received from the microphone and analyzed based on a psycho-acoustic model to provide settings, such as level, pan, and equalization, to an automatic mixer. The automatic mixer mixes the sounds based on the settings and provides audio output to the pilot of the aircraft. The pilot can then use the audio output to more effectively monitor the operations of the aircraft components, which might otherwise be difficult or impossible to hear.
