Organic Carbon Generation Mechanisms in Main and Premise Distribution Systems
Assimilable organic carbon (AOC) is a suspected contributor to growth of microbes, including pathogens, in plumbing systems. Two phases of research were completed to improve knowledge of AOC and other forms of organic carbon in premise plumbing. In the first phase, the AOC Standard Method 9217B was …

Examining the social amplification of risk in Great Lakes areas of concern
… the social impacts of the cleanup process in AOC communities is less clearly understood. This project examines how and to what degree the social amplification of risk framework (SARF) can be used to identify differences in the public understandings of the risks posed by contaminated sediment …

Command in air war : centralized vs. decentralized control of combat airpower
… Air Force developed the Air Operations Center (AOC) to put together battlespace information; it is not yet possible to do this at lower levels, so the AOC has become dominant in controlling air operations. Initially resistant to get involved in ongoing missions, commanders found the AOC was …

Comparison of Groundwater Seepage Modeling in Approximate Original Contour and Geomorphic Valley Fill Design
… method termed Approximate Original Contour (AOC). Seepage from valley fills tends to be elevated with respect to calcium, magnesium, alkalinity and sulfates and there is evidence that, in high concentrations, these ions can contribute to stream degradation. New fluvial geomorphic principals …

Avery Brundage and the 1936 Olympic Games
… Olympic Committee in 1933, the AAU and AOC passed resolutions making American participation contingent upon the cessation of discrimination against German-Jewish athletes. Discriminatory practices did, however, continue. Meanwhile, German officials in charge of the Games' preparations …

Age of information for broadcast and collection in spatially distributed wireless networks
… a fresh update, and the Age of Collection (AoC) as the amount of time that elapses until the base station receives an update from all nodes. We quantify the average broadcast and collection ages in two scenarios: 1) instance-dependent, in which the locations of all nodes and interferers are …

An Evaluation of the Occurrence of Micronuclei and other Nuclear Abnormalities in Fishes from the Great Lakes Basin, United States
… (BUI) occurs at 18 of the 30 areas of concern (AOC) located in the Great Lakes basin within the United States. As each AOC evaluates this specific BUI for possible delisting, biomarkers sensitive to both genotoxic and mutagenic chemicals can be integrated as a possible criterion for delisting. …

Development of a static bioactive stent prototype and dynamic aneurysm-on-a-chip(TM) model for the treatment of aneurysms
… microfluidic model, the Aneurysm-on-a-ChipTM (AOC), was the logical answer to study particle flow within an aneurysm "sac" - this was the dynamic bioactive stent device. The AOC apparatus can track particles/cells when it is coupled to a particle image velocimetry software (PIV) package. The …

Relationship Between Organic Carbon and Opportunistic Pathogens in Simulated Premise Plumbing Systems
… control of assimilable organic carbon (AOC), and biologically degradable organic carbon (BDOC). However, much little is known about the effect of AOC on the proliferation of heterotrophic bacteria and pathogens within premise plumbing. This thesis is the first systematic examination of …

Effect of Various Water Chemistry Factors on Legionella Proliferation and the Premise Plumbing Microbiome Composition
… factors including assimilable organic carbon (AOC) content, granular activated carbon (GAC) biofiltration, plumbing materials, copper concentrations and temperature were investigated using SGWHs. AOC is the carbon available for bacteria growth in drinking water. Results indicated that AOC …

Long-term spatiotemporal water quality and phytoplankton dynamics in Severn Sound, Ontario: a delisted great lakes area of concern
… was previously designated an Area of Concern (AOC) in 1987 as part of the Great Lakes Water Quality Agreement. The AOC designation was largely due to eutrophication, which has been a historical issue in Severn Sound extensively documented by a water quality and phytoplankton monitoring program …

Characterization of Metal Concentrations in Sediment and Water of the Swan Creek Watershed, A Major Tributary in the Maumee River Area of Concern
… of the glaciolacustrine sediments underlying the AOC were analyzed in order to establish the geogenic metals input and to evaluate the extent of anthropogenic inputs by calculating enrichment factors. Metals concentrations in water and sediment samples indicate they are not a concern for water …

The Effect of Natural Organic Matter on UV/H<sub>2</sub>O<sub>2</sub> Treatment and the Effect of UV/H<sub>2</sub>O<sub>2</sub> Treatment on Natural Organic Matter
… of NOM.</p><p>Total assimilable organic carbon (AOC) concentration increased through UV/H<sub>2</sub>O<sub>2</sub> by 14 to 33%, more with conventionally treated (CONV) reactor influent than with Post-GAC influent. The AOC concentration increases generated by MP and LP processes were similar. The …

Characterisation of phenolic antioxidants in fruits and vegetables : bioavailability of raspberry phenolics in humans and rats
… 758-fold in the total FRAP antioxidant capacity (AOC) of the individual products. Those especially rich in antioxidants included peanuts, almonds, broad beans, blueberries, raspberries, strawberries and purple broccoli. The vitamin C and flavonol concentrations were not correlated to the AOC. The …

Técnicas OCDMA con códigos ópticos aleatorios para redes de telecontrol / telemetría en entornos cerrados
… códigos ópticos aleatorios (ROC) y algorítmicos (AOC) recientemente propuestas. Se ha implementado un sistema que simula el funcionamiento de este sistema, consistente en diferentes nodos sensores y actuadores autónomos, y un nodo central que gestiona las comunicaciones del sistema y procesa los …
