A valve operator system having an arm for pivotal mounting to a vehicle and a valve operator head slidingly engaged with a track on the arm. The arm may be pivoted through a wide arc to easily reach a target valve, with the valve operator head easily slid into position. The valve operator head preferably includes a series of rollers that engage longitudinal rods positioned in the opposing rails of a track mounted to the arm. A single track on top of the arm may be used, or two tracks positioned on opposing side surfaces of the arm. Pins or a locking bolt may be used to affix the valve operator head in place once moved into the desired position above the target valve and the arm can be locking into position with a drum brake or locking pins.

Objectives: The Macondo and Bardolino incidents of 2009 and 2010 had similar beginnings but very different outcomes. While Macondo ended in disaster, Bardolino ended without a spill or injury. This case study of these two incidents analyzes and compares the human factors of detecting an influx or kick for each incident. Methods: A set of 147 human factors issues involved in kick detection were assessed, first in aggregate, and then in terms of a step by step narrative of each incident. Next, patterns among the human factors were identified by determining which factors tend to cluster together across a set of 43 incidents. Some factors tend to co-occur with other issues. Results: These clusters of co-occurring issues form two general themes which can be described as a general wariness toward well control versus early engagement and investigation, such as stopping to check for flow. The wariness cluster is more closely associated with shutting in the well early, which is an important objective of safe well control practice. However, a human factors barrier associated with the engagement cluster, considering the possibility of an influx, may have led to the turning point between the Macondo and Bardolino incidents. Novel information: These analyses point to promising locations to focus attention, both for assessing rigs prior to incidents, during investigations after incidents, and most importantly, for researching and developing new technologies and procedures for minimizing or precluding incidents all together.

Huber and O'Reilly (2003) proposed that neural habituation exists to solve a temporal parsing problem, minimizing blending between one word and the next when words are visually presented in rapid succession. They developed a neural dynamics habituation model, explaining the finding that short duration primes produce positive priming whereas long duration primes produce negative repetition priming. The model contains three layers of processing, including a visual input layer, an orthographic layer, and a lexical-semantic layer. The predicted effect of prime duration depends both on this assumed representational hierarchy and the assumption that synaptic depression underlies habituation. The current study tested these assumptions by comparing different kinds of words (e.g., words versus non-words) and different kinds of word-word relations (e.g., associative versus repetition). For each experiment, the predictions of the original model were compared to an alternative model with different representational assumptions. Experiment 1 confirmed the prediction that non-words and inverted words require longer prime durations to eliminate positive repetition priming (i.e., a slower transition from positive to negative priming). Experiment 2 confirmed the prediction that associative priming increases and then decreases with increasing prime duration, but remains positive even with long duration primes. Experiment 3 replicated the effects of repetition and associative priming using a within-subjects design and combined these effects by examining target words that were expected to repeat (e.g., viewing the target word ‘BACK’ after the prime phrase ‘back to'). These results support the originally assumed representational hierarchy and more generally the role of habituation in temporal parsing and priming. © 2017 Elsevier Inc.

Navy ships require the use of hazardous materials (HM) such as hydraulic fluid, paint, acids, corrosives, etc. for daily operations. Navy safety regulations and HM management procedure (i.e. OPNAVINST 5100.19E and CHRMIP), require designated HM storerooms for bulk storage of flammable and corrosive liquids. These storerooms have dedicated fire protection systems, explosion proof electrical fixtures, and forced ventilation. In order to increase efficiency, NAVSEA approved the use of satellite storage lockers that will be placed in the work centers to store a week supply of daily use HM. The objective of this SBIR effort is to develop satellite storage lockers for the stowage of HM to meet the needs of the Fleet. Such lockers will be designed for high corrosion/fire resistance with excellent durability while satisfying all specified safety and operational requirements for storage lockers. Pacific Engineering Inc. (PEI) has a history of producing fire resistance composite components for Naval ships and submarines. Our composite lockers will be lighter than existing steel lockers that weigh between 60 to 225 pounds. PEI will also design superior protection against corrosions, and fire, smoke and toxicity per DDS 078-1 while meeting shock/vibration loads per MIL-STD-810 and Grade B UNDEX blast shock per MIL-S-901. NAVSEA approved the use of satellite storage lockers, which will be placed in the Ship"s work centers, to store a seven (7) day supply of daily use HM.

The broader impact/commercial potential of this Small Business Innovation Research Phase I project is the potential to impact water scarcity in arid and semi-arid geographies within the US and beyond. The proposed photobiological water treatment process utilizes the natural power of photosynthetic microorganisms (diatoms) and sunlight without the use of hazardous chemicals or non-renewable energy to remove contaminants such as silica, calcium, iron, manganese, phosphorus and nitrogen from the concentrated waste streams (brines) from advanced water reclamation and brackish groundwater desalination facilities. Additional clean, (re)usable water can be obtained from the treated brine quite cost-effectively, while reducing the volume of brine by >50% and producing algal biomass as a marketable by-product. This technology will reduce the environmental impact and also potentially improve the efficiency of water treatment. This Phase I project will have broader impacts on the advancement of science and technology related to environmental microbiology, water reuse and water resource management. The experimental data to be generated in this project could reveal many characteristics and fundamental chemistry and biology of brackish water diatoms that have not been studied in detail, as compared with those found in the freshwater and marine environment. The technical objectives in this Phase I research project are to investigate the feasibility of a diatom-based photobiological process for scalant and nutrient removal to recover more fresh water from reverse osmosis concentrate; to characterize the byproducts of this process including organic matter and algal biomass; and to investigate the scale-up challenges. The challenges and opportunities include: (1) the optimization of the biomass growth and constituent removal, including diatom strain screening, (2) impacts of toxic elements, chlorine residuals, salinity, pH, temperature, light sources, intensity, and duration, (3) formation and characterization of byproducts, (4) removal of synthetic organic compounds, such as pharmaceuticals and personal care products, (5) photobiological reactor configuration and hydraulics, and (6) possible uses and economic values of algal biomass. Among them, the major challenges are the possible soluble organic byproduct formation and the relatively modest silica uptake rate. Bench- and pilot-scale experiments will be conducted to optimize the photobiological process to enable a full-scale application with a reasonable footprint. Careful diatom strain/species selection and more detailed chemical and biochemical analyses will also facilitate further process optimization and understanding of the fate of byproducts, their impacts on subsequent desalination, and possible control strategies.
