Abstract: Embodiments relate to a hydraulic fracturing system that includes a blender unit. The system includes an auger and hopper assembly to receive proppant from a proppant source and feed the proppant to the blender unit for mixing with a fluid. A first power source is used to power the blender unit in order to mix the proppant with the fluid and prepare a fracturing slurry. A second power source independently powers the auger and hopper assembly in order to align the hopper of the auger and hopper assembly with a proppant feed from the proppant source. Thus, the auger and hopper assembly can be stowed or deployed without use of the first power source, which is the main power supply to the blender unit.

Abstract: The disclosure relates generally to assortment of products in a retail scenario and more particularly to variety optimization in hyper-localized assortment. In retail scenario, due to availability of limited space in the store, retailers have limited options for displaying a category based on the attribute values of important attributes of the category. In addition, due to increased customer expectations, the attribute values are increasing each day leading to challenges in variety optimization in assortment. The state-of-art techniques address the problem of identification of key attributes for a category, however identifying optimal attribute values among the numerous attribute values specific to location of stores is still challenging.

Abstract: Electric motors are used in oil and gas applications to drive downhole submersible pumps. Upon shutdown of such pumps, a column of fluid remains thereabove. When power is removed, the fluid flows back down the casing causing the motor to rotate backward and generate a voltage that is applied up the power cable to the surface. If the motor is restarted before backspin ceases, damage to the drive shaft is likely. Additionally, the up-hole applied voltage during backspin can pose a shock-risk to personnel at the surface. The present systems and methods minimize these risks by identifying backspin events based on determining phase angle differences at the three phases of the permanent magnet motors and alerting relevant personnel and otherwise preventing re-initiation of motor operation until after backspin has ceased.

Abstract: The invention provides a method involving assessing the vitamin C renal leak status of a human subject, vitamin C renal leak being the clinically inappropriate presence of vitamin C in urine. The method comprises assaying for the concentration of vitamin C in a plasma sample and in collected urine output, whereby the presence of vitamin C in the collected urine output and a concentration of vitamin C in the plasma sample less than the Minimum Elimination Threshold (MET) indicates the presence of vitamin C renal leak. Vitamin C renal leak also can be quantified by determining the fractional excretion of vitamin C (FeVC), which is a measurement of the degree of urinary vitamin C excretion relative to plasma vitamin C concentration corrected by creatinine clearance. The invention also provides a test kit for assessing vitamin C renal leak and a test kit for assessing FeVC.
