A method for producing multiple temporal frames of a time-resolved contrast enhanced magnetic resonance angiogram from a subject using an MR contrast agent by repeatedly applying RF pulses and sampling data in the corresponding image k-space along spiral trajectories that start at the k-space center and spiral outward toward the k-space edge.

A coating material with a primer layer, a middle layer and a surface layer and its method of application which includes the steps: (1) spraying the primer layer material onto an article; (2) spraying or brushing the middle layer material with a first color until satisfactorily coated; (3) repeating step (2) with the middle layer material having a second color and allowing drying; and (4) spraying the surface layer material of PU imitation porcelain material and allow drying to obtain the article with superior imitation ceramic effect. The present invention can be applied to any plastic and poly articles, therefore reducing the exploitation and use of organic soil and natural resources for producing ceramic articles. Since the material used is biodegradable, therefore effectively decreasing the level of pollution and damages to the environment and hence lessening the health hazards to human.

摘要:
Particle separation apparatus separate particles and particle populations using dielectrophoretic (DEP) forces generated by one or more pairs of electrically coupled electrodes separated by a gap. Particles suspended in a fluid are separated by DEP forces generated by the at least one electrode pair at the gap as they travel over a separation zone comprising the electrode pair. Selected particles are deflected relative to the flow of incoming particles by DEP forces that are affected by controlling applied potential, gap width, and the angle linear gaps with respect to fluid flow. The gap between an electrode pair may be a single, linear gap of constant gap, a single linear gap having variable width, or a be in the form of two or more linear gaps having constant or variable gap width having different angles with respect to one another and to the flow.

A method for producing double-component modified molecular sieve comprises adding molecular sieve to an aqueous solution containing phosphorus to form a mixture, allowing the mixture to react at pH of 1-10, temperature of 70-200° C. and pressure of 0.2-1.2 MPa for 10-200 min, and then filtering, drying and baking the resultant to obtain phosphorus-modified molecular sieve, and then adding the phosphorus-modified molecular sieve to an aqueous solution containing silver ions, allowing the phosphorus-modified molecular sieve to react with silver ions at 0-100° C. in dark condition for 30-150 min, and then filtering, drying and baking. The obtained double-component modified molecular sieve contains 88-99 wt % molecular sieve with a ratio of silica to alumina between 15 and 60, 0.5-10 wt % phosphorus (based on oxides) and 0.01-2 wt % silver (based on oxides), all based on dry matter. A catalyst produced from the double-component modified molecular sieve has improved hydrothermal stability and microactivity.

The present invention provides a warning message transmission method and apparatus after the warning message transmission procedure is completed. The method comprises: after sending a WRITE-REPLACE WARNING REQUEST message to an eNB and receiving a WRITE-REPLACE WARNING RESPONSE message corresponding to the WRITE-REPLACE WARNING REQUEST message and returned by the eNB, a mobility management entity (MME) determining areas where warning broadcast fails based on the WRITE-REPLACE WARNING RESPONSE message corresponding to the WRITE-REPLACE WARNING REQUEST message and returned by the eNB, and then controlling the eNB to resend a warning message to the areas where warning broadcast fails. The present invention can ensure that disastrous information associated with the ETWS can be timely and effectively notified to all users in areas where broadcast fails so as send an escape or precaution warning to them to further minimize huge losses of human life and property when the disaster comes.

摘要:
An in-situ gas flow measurement controller measures the temperature and rate of pressure drop upstream from a flow control device (FCD). The controller samples the pressure and temperature data and applies the equivalent of a decimating filter to the data to produce filtered data at a slower sampling rate. The controller derives timestamps by counting ticks from the sampling clock of the A/D converter that is sampling the pressure at regular intervals to ensure the timestamps associated with the pressure samples are accurate and do not contain jitter that is associated with software clocks. The controller additionally normalizes the temperature reading to account for power supply fluctuations, filters out noise from the pressure and temperature readings, and excludes data during periods of instability. It calculates the gas flow rate accounting for possible non-linearities in the pressure measurements, and provides the computed gas flow measurement via one of many possible interfaces.
