Abstract: Biomarkers and methods for identifying, verifying and confirming circulating serum-based microRNAs. The microRNAs (PARKmiRs) can be used to differentiate patient's suffering from Alzheimer's disease (AD) from non-AD patients.

Abstract: Well stimulating fluids and methods may use a first and a second chelating agent, e.g., diethylene triamine pentaacetic acid (DTPA), glutamic diacetic acid (GLDA), and/or hydroxyethyl ethylene diamine triacetic acid (HEDTA), particularly in amounts of from 1 to 10 wt. %, to control iron precipitation during the stimulation process. Such fluids can stabilize iron ions without precipitation to manage the efficiency and performance of the stimulation fluid. Such stimulation fluids can be used with for highly concentrated HCl solutions, e.g., more than 20 up to 28 wt. % or more, that are useful in emulsified acid formulations in acid fracturing or acidizing of carbonate formations.

Abstract: A building management system includes a plurality of meters configured to provide data samples of a plurality of points relating to a building and a space hierarchy database configured to store a sibling relationship for each of the points. Each sibling relationship identifies two or more of the points as sibling points. The building management system includes a batch metrics engine configured to receive a first data sample of a first point, access the sibling relationship for the first point to identify one or more sibling points of the first point, aggregate the first data sample with data samples of the sibling points to generate a batch, and calculate an aggregate metric using the first data sample and the other data samples in the batch. The building management system also includes a controller configured to adjust an operation of building equipment based on the aggregate metric.

Abstract: A drilling fluid containing a liquid phase, a weighting agent (e.g. barite, calcite, ilmenite), and perlite is described. The drilling fluid may further contain one or more additives including a defoamer, a fluid-loss control agent, a viscosifier, an antiscalant, a deflocculant, a lubricant, a clay stabilizer, a bridging agent, and a surfactant. A process of drilling a subterranean geological formation utilizing the drilling fluid is also specified. The introduction of perlite to the drilling fluid is effective in reducing the thickness and permeability of filter cakes formed during the drilling process.

Abstract: A building management system for monitoring equipment status is provided. The building management system includes a processing circuit configured to generate one or more diagnostics for a piece of building equipment based on one or more faults. The processing circuit is further configured to generate a work order based on the one or more diagnostics. The processing circuit is further configured to cause the work order to include task details for resolving the one or more faults. The task details are based on the one or more diagnostics associated with the one or more faults.

Abstract: A system and method for assessing the effectiveness of automation and control units (HVAC, Elevator, water supply, etc.) implemented in a Building Management System (BMS) of a building is illustrated. Initially, the system reads/receives a metadata corresponding to all the sensing and control requirements based on the design and usage of the building, and further, assesses the implementation of the control routines for determining how the automation objectives are being met in the building by each of the currently implemented automation and control units in the building. The system further assesses how all the automation and control units work together in tandem. This assessment is then interpreted on based on different vectors. Finally, the system identifies gaps based on the assessment and generates recommendations to address these gaps.

Abstract: A building management system for monitoring equipment status is provided. The building management system includes a processing circuit configured to generate one or more constants for a piece of building equipment based on thresholds and device specific templates. The constants are equation based relationships between a value and a threshold. The processing circuit is further configured to generate one or more sub-rules based on the one or more constants and one or more equipment points. The sub-rules are equation based relationships between the one or more constants and the one or more equipment points. The processing circuit is further configured to generate a rule based on the one or more sub-rules and the one or more equipment points. The rule is an equation based relationship between the one or more sub-rules and the one or more equipment points and indicates whether the piece of building equipment is experiencing a fault.

Abstract: A method is described for removing a barite-quartz and a calcite-quartz filter cake from a well bore. The method involves contacting the filter cake with a first composition comprising NH4F, NaBrO3, NH4Cl, and NaNO2. The NH4Cl and NaNO2 react exothermically, and the heat produced drives the endothermic reaction of NH4F and NaBrO3, which produces HF for dissolution of the quartz in the filter cake. Filter cake comprising barite may be further treated with a second composition comprising a converting agent and a chelating agent. Filter cake comprising calcite may be treated with a first composition having an excess of NH4Cl and NaBrO3, which react to produce HCl for calcite dissolution.

The biomolecule is selected to interact with the target clinical markers. The biosensor can be used as an in-situ or an ex-situ device to detect and measure the presence of the target clinical markers.
