摘要： Methods and apparatus are disclosed for correcting for gravitational force variation in measuring the melt flow index of a polymer at a location. For example, ample, some embodiments may involve determining a value representing an extent to which gravitational force at the location varies from standard gravity, such as based at least in part upon the latitude of the location. The value may be used in correcting the melt flow index measured for the polymer using a plastometer at the location.

摘要： A method for evaluating Dry Eye Disease (“DED”) in a human or animal subject is provided. Thread thinning dynamics of a tear sample of the subject are determined using an acoustically-driven microfluidic extensional rheometry instrument. At least one physical parameter value of the tear sample is calculated based at least in part on the determined thread thinning dynamics. DED is evaluated based at least in part on the at least one calculated physical parameter value of the tear sample. A device for evaluating Dry Eye Disease (DED) in a human or animal subject is also provided. The device includes an acoustically-driven microfluidic extensional rheometry instrument and a processing device configured to evaluate DED based at least in part on the calculated at least one physical parameter value of the tear sample.

摘要： The apparatus for measuring disentrainment rate of air includes a Confined Plunging Liquid Jet Reactor (CPLJR) having a downcomer column surrounding a liquid jet. The end of the downcomer column is partially immersed in a receiving liquid pool contained in a reservoir. A conical ring is placed in the downcomer column below the liquid jet, the ring bearing against the wall of the downcomer column and forming a seal to define a headspace in the column. A gas supply and first bubble meter are connected to the column above the conical ring to supply gas and measure total entrainment. A second bubble meter connected to the headspace between the ring and the receiving pool measures disentrainment, and a third bubble meter connected to headspace above the receiving pool outside the column measures net entrainment.

摘要： A monitoring system for distributed utilities. A generation device is provided for converting an available resource to a desired utility; the resource may be water, in which case the generator is a purifier for providing potable water, or, alternatively, the generator may convert a fuel to electrical power. In either case, an input sensor is provided for measuring input to the generation device, while an output sensor is provided for measuring consumption of output from the generation device. The monitoring system has a controller for concatenating measured input and consumption of output on the basis of the input and output sensors. Measured parameters are telemetered to a remote site where utility generation and use are monitored and may also be controlled.

摘要： In some embodiments, the invention provides an in vitro method for identifying a patient as likely as likely to require a transfusion of at least six units of blood in six hours or less. The method comprise, consists essentially of, or consists of (a) analyzing a sample of blood from a patient with a viscoelastic analysis assay to obtain a coagulation characteristic value that is independent of time of the patient; and (b) comparing the coagulation characteristic value of the patient to a coagulation characteristic value that is independent of time of a control, wherein the coagulation characteristic value of the patient that is lower than the coagulation characteristic value of the control identifies the patient as likely to require a transfusion of at least six units of blood in six hours or less.

摘要： A method for determining the viscosity of a conveying fluid conveyed by a pump, in which an operating value is detected and is fed to an evaluation unit. The method includes providing a reference fluid, recording a reference performance curve resulting from the reference fluid during test operation of the pump at a predetermined operating parameter of the pump, recording an operating performance curve resulting from the conveying fluid during conveying operation of the pump at the predetermined operating parameter of the pump, determining the viscosity of the conveying fluid from a deviation of the operating performance curve from the reference performance curve by a viscosity correction algorithm stored in the evaluation unit.
