Abstract: A method and system for irrigating a field adjacent a watercourse is disclosed comprising a plurality of pumps along the watercourse and measuring from time to time at a plurality of measuring locations the salinity, the pH, the temperature and the turbidity of the water. The measuring locations are different from the pumping locations. A real time salinity, pH, temperature and turbidity at the pumping locations is predicted from the measured values and the pumps selectively disabled or enabled on the predicted salinity, pH, temperature and/or the turbidity. Additionally, there is disclosed an Alternate Wetting and Drying (AWD) method/system for irrigating a field using a pump comprising an outlet supplying water to the field and an inlet connected to a water source. The method/system comprises a sensor placed at a location in the field for sensing a water depth below a surface of the field and transmitting the water depth to a controller located remotely from the sensing location using a wireless connection.

Abstract: A delivery sheath includes an outer tubular layer and an initially folded inner tubular layer. When an implant passes therethrough, the outer tubular layer expands and the inner tubular layer unfolds into an expanded lumen diameter. The sheath may also include selectively placed longitudinal support rods that mediate friction between the inner and outer tubular layers to facilitate easy expansion, thereby reducing the push force needed to advance the implant through the sheath's lumen.

The first layer is positionable adjacent the user. A filtering layer is positioned between the first and second layer, and the filtering layer includes a piezoelectric film.

Abstract: The present invention provides methods of treating infantile spasms in a subject in need thereof. In certain embodiments, the method comprises administering to the subject both vigabatrin (VGB) and insulin-like growth factor 1 (IGF-1), a biologically active fragment thereof, or any derivative thereof.

Abstract: An assay preparation device is an apparatus that is used to contain a variety of reagents and samples, to combine these fluids in a desirable order, to agitate the fluids through rotation of adsorbent petals, to contain the resulting waste products, and to allow for wavelength analysis of the results. The apparatus includes a reaction chamber, an intake port, a sample-retaining spinner, a first reading slit, a plurality of fluid-retaining receptacles, a plurality of input valves, and a waste valve. The plurality of input valves is connected to the plurality of fluid-retaining receptacles, allowing the user to control fluid flow into the reaction chamber. The sample-retaining spinner collects the fluids in the reaction chamber. Upon reaction completion, the waste valve is opened to allow for removal of fluids from the reaction chamber. The first reading slit provides a window for wavelength examination tools to examine and analyze the reaction results.

Abstract: A rotating control device can include a latch assembly with a lock ring that permits displacement of an inner mandrel in one longitudinal direction, and prevents displacement of the inner mandrel in an opposite longitudinal direction. Another rotating control device can include a latch assembly and an equalization valve having an open configuration in which fluid communication is permitted between an exterior and an interior of the rotating control device through the equalization valve, the latch assembly changing from a latched to an unlatched configuration only when the equalization valve is in the open configuration. A method of installing a rotating control device can include releasing a running tool from the rotating control device by producing relative rotation between components of the running tool.

Abstract: The present invention relates to systems, methods and devices for metabolomic-based classification of biological samples, and interpretation methods for biomarker discovery.

Abstract: Described herein are low-profile electrodes for use with an angioplasty shockwave catheter. A low-profile electrode assembly may have an inner electrode, an insulating layer disposed over the inner electrode such that an opening in the insulating layer is aligned with the inner electrode, and an outer electrode sheath disposed over the insulating layer such that an opening in the outer electrode sheath is coaxially aligned with the opening in the insulating layer. This layered configuration allows for the generation of shockwaves that propagate outward from the side of the catheter. In some variations, the electrode assembly has a second inner electrode, and the insulating layer and outer electrode may each have a second opening that are coaxially aligned with the second inner electrode. An angioplasty shockwave catheter may have a plurality of such low-profile electrode assemblies along its length to break up calcified plaques along a length of a vessel.
