    A brief study involving collection and analysis of street sweepings was undertaken to provide the U.S. Army Corps of Engineers with data on physical, chemical, and biological characteristics of dust and dirt accumulating on Portland streets. Most of the analyses selected were based on the pollutant loads predicted by the Storage, Treatment, Overflow, and Runoff Model (STORM). Five different basins were selected for sampling, and samples were collected three times in each basin. Because the literature reports no methodology for analysis of dust and dirt, the analytical methodology is described in detail. Results of the analyses are summarized in table 1.

  17. Portland, Mount Hood, & Columbia River Gorge, Oregon, Perspective View

    NASA Technical Reports Server (NTRS)

    2004-01-01

    Portland, the largest city in Oregon, is located on the Columbia River at the northern end of the Willamette Valley. On clear days, Mount Hood highlights the Cascade Mountains backdrop to the east. The Columbia is the largest river in the American Northwest and is navigable up to and well beyond Portland. It is also the only river to fully cross the Cascade Range, and has carved the Columbia River Gorge, which is seen in the left-central part of this view. A series of dams along the river, at topographically favorable sites, provide substantial hydroelectric power to the region.

    This perspective view was generated using topographic data from the Shuttle Radar Topography Mission (SRTM), a Landsat satellite image, and a false sky. Topographic expression is vertically exaggerated two times.

    Landsat has been providing visible and infrared views of the Earth since 1972. SRTM elevation data substantially help in analyzing Landsat images by revealing the third dimension of Earth's surface, topographic height. The Landsat archive is managed by the U.S. Geological Survey's Eros Data Center (USGS EDC).

    Elevation data used in this image were acquired by the Shuttle Radar Topography Mission (SRTM) aboard the Space Shuttle Endeavour, launched on February 11, 2000. SRTM used the same radar instrument that comprised the Spaceborne Imaging Radar-C/X-Band Synthetic Aperture Radar (SIR-C/X-SAR) that flew twice on the Space Shuttle Endeavour in 1994. SRTM was designed to collect three-dimensional measurements of the Earth's surface. To collect the 3-D data, engineers added a 60-meter-long (200-foot) mast, installed additional C-band and X-band antennas, and improved tracking and navigation devices.

  19. Developing flood-inundation maps for Johnson Creek, Portland, Oregon

    USGS Publications Warehouse

    Stonewall, Adam J.; Beal, Benjamin A.

    2017-04-14

    Digital flood-inundation maps were created for a 12.9‑mile reach of Johnson Creek by the U.S. Geological Survey (USGS). The flood-inundation maps depict estimates of water depth and areal extent of flooding from the mouth of Johnson Creek to just upstream of Southeast 174th Avenue in Portland, Oregon. Each flood-inundation map is based on a specific water level and associated streamflow at the USGS streamgage, Johnson Creek at Sycamore, Oregon (14211500), which is located near the upstream boundary of the maps. The maps produced by the USGS, and the forecasted flood hydrographs produced by National Weather Service River Forecast Center can be accessed through the USGS Flood Inundation Mapper Web site (http://wimcloud.usgs.gov/apps/FIM/FloodInundationMapper.html).Water-surface elevations were computed for Johnson Creek using a combined one-dimensional and two‑dimensional unsteady hydraulic flow model. The model was calibrated using data collected from the flood of December 2015 (including the calculated streamflows at two USGS streamgages on Johnson Creek) and validated with data from the flood of January 2009. Results were typically within 0.6 foot (ft) of recorded or measured water-surface elevations from the December 2015 flood, and within 0.8 ft from the January 2009 flood. Output from the hydraulic model was used to create eight flood inundation maps ranging in stage from 9 to 16 ft. Boundary condition hydrographs were identical in shape to those from the December 2015 flood event, but were scaled up or down to produce the amount of streamflow corresponding to a specific water-surface elevation at the Sycamore streamgage (14211500). Sensitivity analyses using other hydrograph shapes, and a version of the model in which the peak flow is maintained for an extended period of time, showed minimal variation, except for overbank areas near the Foster Floodplain Natural Area.Simulated water-surface profiles were combined with light detection and ranging (lidar

  20. Evaluation of flood inundation in Crystal Springs Creek, Portland, Oregon

    2016-05-25

    Efforts to improve fish passage have resulted in the replacement of six culverts in Crystal Springs Creek in Portland, Oregon. Two more culverts are scheduled to be replaced at Glenwood Street and Bybee Boulevard (Glenwood/Bybee project) in 2016. Recently acquired data have allowed for a more comprehensive understanding of the hydrology of the creek and the topography of the watershed. To evaluate the impact of the culvert replacements and recent hydrologic data, a Hydrologic Engineering Center-River Analysis System hydraulic model was developed to estimate water-surface elevations during high-flow events. Longitudinal surface-water profiles were modeled to evaluate current conditions and future conditions using the design plans for the culverts to be installed in 2016. Additional profiles were created to compare with the results from the most recent flood model approved by the Federal Emergency Management Agency for Crystal Springs Creek and to evaluate model sensitivity.Model simulation results show that water-surface elevations during high-flow events will be lower than estimates from previous models, primarily due to lower estimates of streamflow associated with the 0.01 and 0.002 annual exceedance probability (AEP) events. Additionally, recent culvert replacements have resulted in less ponding behind crossings. Similarly, model simulation results show that the proposed replacement culverts at Glenwood Street and Bybee Boulevard will result in lower water-surface elevations during high-flow events upstream of the proposed project. Wider culverts will allow more water to pass through crossings, resulting in slightly higher water-surface elevations downstream of the project during high-flows than water-surface elevations that would occur under current conditions. For the 0.01 AEP event, the water-surface elevations downstream of the Glenwood/Bybee project will be an average of 0.05 ft and a maximum of 0.07 ft higher than current conditions. Similarly, for the 0

  8. Costs and benefits of bicycling investments in Portland, Oregon.

    PubMed

    Gotschi, Thomas

    2011-01-01

    Promoting bicycling has great potential to increase overall physical activity; however, significant uncertainty exists with regard to the amount and effectiveness of investment needed for infrastructure. The objective of this study is to assess how costs of Portland's past and planned investments in bicycling relate to health and other benefits. Costs of investment plans are compared with 2 types of monetized health benefits, health care cost savings and value of statistical life savings. Levels of bicycling are estimated using past trends, future mode share goals, and a traffic demand model. By 2040, investments in the range of $138 to $605 million will result in health care cost savings of $388 to $594 million, fuel savings of $143 to $218 million, and savings in value of statistical lives of $7 to $12 billion. The benefit-cost ratios for health care and fuel savings are between 3.8 and 1.2 to 1, and an order of magnitude larger when value of statistical lives is used. This first of its kind cost-benefit analysis of investments in bicycling in a US city shows that such efforts are cost-effective, even when only a limited selection of benefits is considered.

    2009-01-01

    We investigated the prevalence of Baylisascaris procyonis in raccoons living in the metropolitan area of Portland, Oregon, USA, in order to assess the potential public health risk involved in the transmission of B. procyonis to humans and companion animals. Sixty-nine euthanized raccoons were collected from Portland wildlife-control agencies. Infection with B. procyonis was determined through the harvesting of adult worms from raccoon intestines during necropsy and by fecal analysis using modified double-centrifugation technique with a sugar-flotation solution. Fifty-eight percent of sampled raccoons were found to be infected with B. procyonis. Juveniles represented a greater percentage (64%) of raccoons captured by wildlife-control agents and were found to have the highest prevalence (70%) and heavier adult worm burdens (mean=35 worms). No gender bias was evident. This is one of the few studies of Baylisascaris prevalence in the Pacific Northwest, and it demonstrates that there is a high prevalence of B. procyonis in raccoons inhabiting the Portland area. This factor should be considered in raccoon relocation and management. The data also suggest that juvenile raccoons are the major potential source of B. procyonis contamination in the Portland community and may merit special attention to minimize their interaction with humans.

    2009-01-01

    Water samples for tritium/helium-3 age dating were collected from 12 shallow monitoring wells in the Portland basin, Oregon, in 1997, and again in 1998. Robust tritium/helium-3 apparent (piston-flow) ages were obtained for water samples from 10 of the 12 wells; apparent ages ranged from 1.1 to 21.2 years. Method precision was demonstrated by close agreement between data collected in 1997 and 1998. Tritium/helium-3 apparent ages generally increase with increasing depth below the water table, and agree well with age/depth relations based on assumptions of effects of recharge rate on vertical ground-water movement.

    SciTech Connect

    Revey, G.F.; Painter, D.Z.

    1995-12-31

    Frontier/Traylor Joint Venture is presently constructing a section of the Tri-County Metropolitan Transit District of Oregon`s (TRI-MET) Westside Light Rail System. This new section will extend Portland`s existing transit system to the western suburbs of Beaverton and Hillsboro. The drill-blast excavations at this project include 10,000 feet of 20 foot tunnel, 18 cross passages, three shafts, an underground railway station, and a U-wall open cut. From a blast designer`s perspective, this job has been extremely challenging. Blast vibration is limited to 0.5 ips at 200 feet or at the nearest structure, and airblast is limited to 129 dB--linear peak and 96 dB--C scale. The tunnels pass under heavily built up areas and have top of tunnel to surface cover distances as low as 70 feet. Surface blasting in the 26,000 cubic yard U-wall excavation was limited to five short nighttime periods due to its proximity to the very busy highway 26. This paper describes the techniques that were used to develop safe blasting designs for the TRI-MET Surface blasts and tunnel rounds. It also discusses the measures that were necessary to mitigate noise, vibration, and flyrock.

  15. Comparative approaches to measuring food access in urban areas: the case of Portland, Oregon.

    PubMed

    Sparks, Andrea L; Bania, Neil; Leete, Laura

    2011-01-01

    GIS methods are used to construct measures of food access for neighbourhoods in the Portland, Oregon, US metropolitan area and the sensitivity of such measures to methodological variation is examined. The level of aggregation of data inputs is varied and the effect of using both Euclidean and street network distances is tested. It is found that, regardless of the level of geographical disaggregation, distance-based measures generate approximately the same conclusions about the distribution of food access in the area. It is also found that, while the relationship between street network and Euclidean distances varies with population density, measures computed with either construct generate the same relative patterns of food access. These findings suggest that results from food access studies employing disparate methodologies can often be compared.

  16. Economic deprivation and racial segregation: comparing Superfund sites in Portland, Oregon and Detroit, Michigan.

    PubMed

    Smith, Chad L

    2009-09-01

    The research presented here weighs the ability of two major explanations of social inequality-Massey and Denton's racial segregation explanation and Wilson's emphasis on economic deprivation (concentrated poverty)-to predict environmental inequality. Two sets of logistic regression analyses are used to predict the location of Superfund sites in Portland, Oregon and Detroit, Michigan providing a conditional understanding of environmental inequality within a larger sociological context. The analysis includes a general examination of the two theories in all census tracts in both cities and a set of analyses focusing upon Black neighborhoods in Detroit. The findings indicate that there is support for explanations of environmental inequality that include both racial segregation and economic deprivation, but that the more powerful of the two is economic deprivation. The results suggest that even though African-American neighborhoods disproportionately house Superfund sites, these facilities are more likely to be located in Black neighborhoods that are economically deprived.

  17. Food mirages: geographic and economic barriers to healthful food access in Portland, Oregon.

    PubMed

    Breyer, Betsy; Voss-Andreae, Adriana

    2013-11-01

    This paper investigated the role of grocery store prices in structuring food access for low-income households in Portland, Oregon. We conducted a detailed healthful foods market basket survey and developed an index of store cost based on the USDA Thrifty Food Plan. Using this index, we estimated the difference in street-network distance between the nearest low-cost grocery store and the nearest grocery store irrespective of cost. Spatial regression of this metric in relation to income, poverty, and gentrification at the census tract scale lead to a new theory regarding food access in the urban landscape. Food deserts are sparse in Portland, but food mirages are abundant, particularly in gentrifying areas where poverty remains high. In a food mirage, grocery stores are plentiful but prices are beyond the means of low-income households, making them functionally equivalent to food deserts in that a long journey to obtain affordable, nutritious food is required in either case. Results suggested that evaluation of food environments should, at a minimum, consider both proximity and price in assessing healthy food access for low-income households.

    This U.S. Department of Energy GATEWAY Demonstration project studied the applicability of light-emitting diode (LED) luminaires for commercial parking garage applications. High-pressure sodium (HPS) area luminaires were replaced with new LED area luminaires. The project was supported under the U.S. Department of Energy (DOE) Solid State Lighting Program. Other participants in the demonstration project included Providence Portland Medical Center in Portland, Oregon, the Energy Trust of Oregon, and Lighting Sciences Group (LSG) Inc. Pacific Northwest National Laboratory (PNNL) conducted the measurements and analysis of the results. PNNL manages GATEWAY demonstrations for DOE and represents their perspective in the conduct of the work. Quantitative and qualitative measurements of light and electrical power were taken at the site for both HPS and LED light sources. Economic costs were estimated and garage users’ responses to the new light sources were gauged with a survey. Six LED luminaires were installed in the below-ground parking level A, replacing six existing 150W HPS lamps spread out over two rows of parking spaces. Illuminance measurements were taken at floor level approximately every 4 ft on a 60-ft x 40-ft grid to measure light output of these LED luminaires which were termed the “Version 1” luminaires. PNNL conducted power measurements of the circuit in the garage to which the 6 luminaires were connected and determined that they drew an average of 82 W per lamp. An improved LED luminaire, Version 2, was installed in Level B of the parking garage. Illuminance measurements were not made of this second luminaire on site due to higher traffic conditions, but photometric measurements of this lamp and Version 1 were made in an independent testing laboratory and power usage for Version 2 was also measured. Version 1 was found to produce 3600 lumens and Version 2 was found to produce 4700 lumens of light and to consume 78 Watts. Maximum and minimum light

    In October 1983 the US Geological Survey, in cooperation with the US Army Corp of Engineers, collected bottom-material and water samples from Portland Harbor, Oregon to determine concentrations of trace metals and organic compounds in elutriate-test filtrate and bottom material. Of the trace metals examined in bottom material, concentrations of cadmium slightly exceed those of local rocks, whereas lead and zinc exceedance is substantially larger. Of the organochlorine compounds examined in bottom material chlordane, DDD, DDE, DDT, dieldrin, and polychlorinated biphenyls (PCB's) were detected and quantified in at least 30% of the samples tested. A large DDT concentrations near Doane Lake outlet is indicative of recent contamination. Polychlorinated biphenyls are ubiquitous in bottom sediments; median concentrations are nearly 65 micrograms/kilogram and as large as 550 microgram/kilogram PCB loading to the Columbia River from Willamette River suspended sediment has been estimated to be 72 kilograms/year, nearly five times the PCB dredge load of 15 kilogram/year. The acid and base-neutral extractable di-n-butyl phthalate and bis (2-methylhexyl)phthalate occur in sediments of Terminal No. 2 in concentrations as large as 1,965 and 2,200 micrograms/ kilogram, respectively. Of the trace metals examined in both standard and oxic elutriate-test filtrate, only copper concentration in an oxic elutriate-test filtrate exceeded the water quality criteria. 34 refs., 8 figs., 12 tabs.

    Workers are exposed to potential irritants and allergens with constant introduction of new industrial chemicals in the workplace. Characterize the final diagnoses, demographics, occupations, exposures, clinical presentations, patch test results, dermatologic histories, and risk factors of workers evaluated for suspected work-related allergic contact dermatitis (ACD). A retrospective chart review of 310 workers' compensation independent medical examinations evaluated for suspected work-related ACD was performed. Workers were seen in a community dermatology clinic in Portland, Oregon, from 2005 to 2014. Evaluation included history, physical examination, patch testing, and further diagnostic workup when indicated. Hand dermatitis was the most common presentation (n = 148, 47.7%). Prevalent occupations included health care workers (n = 51, 16.5%), custodial staff (n = 41, 13.2%), and machinists (n = 36, 11.6%). Allergic contact dermatitis (47.5%) was more common than irritant contact dermatitis (ICD) (38.9%) in those diagnosed as having occupational skin disease (n = 185). The highest-frequency work-related allergens were thiuram mix (21 of 88, 23.9%), carba mix (20 of 88, 22.7%), potassium dichromate (9 of 88, 10.2%), and epoxy resin (9 of 88, 10.2%). Allergic contact dermatitis and ICD are common occupational skin disorders. In this population of workers' compensation referrals, ACD was more common, with 73.3% of those cases work related, compared with 86.7% of ICD. Blue collar work and wet work were risk factors for the development of ACD and ICD.

    1994-01-01

    A numerical model of the ground-water flow-system in the Portland Basin, Oregon and Washington, was used to test and refine the conceptual understanding of the flow system and estimate the effects of past and future human-caused changes to the ground-water system. Recharge to the basin in 1987-88 consisted primarily of 1,440 cubic feet per second (ft3/s) from direct infiltration of precipitation, but was augmented in unsewered urban areas by 62 ft3/s from runoff to drywells and 27 ft3/s from on-site waste disposal systems. Forty-nine percent of the recharge in the basin infiltrates through the Troutdale gravel aquifer and 22 percent through the unconsoli- dated sedimentary aquifer. The unconsolidated sedimentary aquifer and Troutdale gravel aquifer supplied 85 percent of 1987-88 pumpage. Recharge under pre-development conditions was 180 ft3/s (12 percent) more than in 1987-88 owing to the lack of impervious surfaces associated with urbanization. Simulation of the effects of the increased recharge and no well discharge indicates that water levels could have declined as much as 50 feet within the Troutdale gravel in southern Clark County in response to municipal pumping. The combination of reduced recharge and increased pumpage could have reduced discharge to large rivers by 25 percent, and discharge to small rivers and streams by 16 percent, since pre-development conditions. One hypothetical condition for future ground-water development was simulated to test the effects of additional pumping stress on the ground-water system. Pumpage estimates in this condition were based on projected municipal supply demands in Clark County through the year 2010 and on limited use of the City of Portland Columbia South Shore well-field. The hypothetical pumpage was 55 percent (92 ft3/s) greater than 1987-88 pumpage. Equilibrium water-level declines were as much as 20-40 ft in the Troutdale gravel aquifer in Clark County and in the Troutdale sandstone aquifer underlying the Columbia

    The McCormick and Baxter Creosoting site is located on the Willamette River in Portland, Oregon. ATSDR considers the site to have been a public health hazard for former plant workers because of past ingestion exposure to arsenic, creosote, pentachlorophenol, polychlorinated dibenzodioxins, and dibenzofurans at levels of public health concern. The site also poses an ongoing and future public health hazard because people might encounter hazardous chemicals along the shoreline on or near the site at levels that can damage the skin, as was reported to have happened to two boys. Finally, dioxin levels would pose a public health hazard if people subsist on crayfish and suckers contaminated with polychlorinated dibenzodioxins and dibenzofurans.

    Human papillomavirus (HPV) vaccine should reduce cervical dysplasia before cervical cancer. However, dysplasia diagnosis is screening-dependent. Accurate screening estimates are needed. To estimate the percentage of women in a geographic population that has had cervical cancer screening. We analyzed claims data for (Papanicolau) Pap tests from 2008-2012 to estimate the percentage of insured women aged 18-39 years screened. We estimated screening in uninsured women by dividing the percentage of insured Behavioral Risk Factor Surveillance Survey respondents reporting previous-year testing by the percentage of uninsured respondents reporting previous-year testing, and multiplying this ratio by claims-based estimates of insured women with previous-year screening. We calculated a simple weighted average of the two estimates to estimate overall screening percentage. We estimated credible intervals using Monte-Carlo simulations. During 2008-2012, an annual average of 29.6% of women aged 18-39 years were screened. Screening increased from 2008 to 2009 in all age groups. During 2009-2012, the screening percentages decreased for all groups, but declined most in women aged 18-20 years, from 21.5% to 5.4%. Within age groups, compared to 2009, credible intervals did not overlap during 2011 (except age group 21-29 years) and 2012, and credible intervals in the 18-20 year group did not overlap with older groups in any year. This introduces a novel method to estimate population-level cervical cancer screening. Overall, percentage of women screened in Portland, Oregon fell following changes in screening recommendations released in 2009 and later modified in 2012. Copyright © 2016 Elsevier Ltd.

    1997-06-01

    This report discusses water, energy, and cost savings that can be achieved in a commercial laundry through the use of a wastewater recycling and heat recovery system. Cost savings are achieved through reductions in water use, reduction in sewage charges (typically based on water use), reductions in water heating energy, and potential reductions in water treatment chemicals because the recycled water has already been treated with soaps and conditioners. A recovery system saves water by recycling wash water that would normally be dumped into the city sewage system. Recycling the wash water produces considerable energy savings because the recycled water has a higher temperature than fresh water. As a result, a hot water heater consumes less energy to heat the recycled water. The demonstration project discussed in this report was based in a large commercial laundry in Portland, Oregon. The laundry serves a large hotel/motel chain and processes an average of 25,000 pounds of laundry per day. A wastewater recovery system using a membrane microfiltration unit (MFU) was installed in the laundry in September 1995. Time series data of the water and energy consumption of the laundry were taken before and after installation of the MFU. Energy savings were measured by performing a thermal energy balance around the washing machines. Water savings were calculated by metering volumetric flow rates. After a period of approximately five months, the MFU has achieved final results of 52 percent savings in water consumption and 44 percent savings in energy to heat water. This five-month period represents a learning curve during which several small technical improvements were made to the MFU and laundry staff adjusted laundry operations to maximize the benefits of the MFU. An economic analysis discusses the impact of capital investment, daily consumption, and local utility rates on the payback period.

    Portland, Oregon, and San Diego, California worked independently, but on similar tracks to implement and study multi-family recycling systems. This report examines the implementation and lessons learned from these programs. Each city adapted the program to fit their local environment. San Diego focussed their outreach on garbage haulers as well as property managers. San Diego worked to promote the participation of the private sector in multifamily recycling and to encourage haulers to duplicate the program with their other multifamily customers. Portland focussed its outreach on the property owners and managers because a new Oregon law requires that landlords provide recycling service and education to all their tenants. The end product in each city was onsite recycling systems and tenant education serving nearly 9,000 multi-family units combined. Newspapers comprised the largest material by volume and weight collected in each city and accounted for the majority of the estimated energy savings in each program. Although recycling is often thought of as being good from an environmental and resource perspective, results from the energy savings analyses show that there is also a considerable energy savings potential from multifamily recycling.

  10. Microbial dechlorination of polychlorinated biphenyls, dibenzo-p-dioxins, and -furans at the Portland Harbor Superfund site, Oregon, USA.

    The Portland Harbor (Oregon, USA) has been declared a "Superfund" site because it is impacted by a variety of contaminants, including polychlorinated biphenyls (PCBs) and polychlorinated dibenzo-p-dioxins and -furans (PCDD/Fs). Using data collected in the remedial investigation, concentrations of PCBs and PCDD/Fs in sediment and water were examined using positive matrix factorization to look for evidence that PCBs and PCDD/Fs are dechlorinated by anaerobic bacteria. This process has long been known to occur in sediments. Recently, it has been recognized that PCB and PCDD/F dechlorination may also occur in other anaerobic environments, such as in landfills, sewers, and groundwater. The results indicate that a factor related to the dechlorination of PCBs and PCDD/Fs was present in the water but not in the sediment. Spatial patterns in dechlorination products suggest that they come primarily from groundwater. Dechlorination products comprise 22% of the PCBs in the water. The Portland Harbor therefore represents the third major US watershed in which PCBs appear to undergo dechlorination in an environment other than sediment, suggesting that the microbial dechlorination of PCBs and PCDD/Fs is more common than previously assumed. In addition, the Portland Harbor is impacted by PCBs generated inadvertently during the production of pigments, such as PCB 11, which alone exceeded the 64 pg/L federal water quality standard for the sum of PCBs in two of 120 whole water samples.

    A cross-sectional evaluation of semen quality (sperm concentration, pH, volume, viability, motility, velocity and morphology) was made among men employed at the Precision Castparts Corporation, Portland, Oregon in response to a management request to evaluate effects of exposure to 2-ethoxyethanol (2EE). About 80 male workers were potentially exposed to 2EE, used as a binder in investment casting. Full-shift breathing-zone airborne exposures to 2EE ranged from not detectable to 23.8 ppm. The average sperm count per ejaculate among the exposed workers was significantly lower than that of the unexposed comparison group, 113 versus 154 million sperm/ejaculate. Average sperm concentrations of both groups were significantly lower than the average for other occupational populations. The authors conclude that there is a possible effect of 2EE exposure on sperm count among these workers, but other factors may be affecting semen quality of both exposed and unexposed workers.

    A Cormack-Jolly-Seber mark-recapture model was developed to provide reach-specific survival estimates for juvenile Chinook salmon. A portion of the tagged population overwintered in the Willamette River Basin and outmigrated several months after release. As a result, survival estimates from the model would have been negatively biased by factors such as acoustic tag failure and tag loss. Data from laboratory studies were incorporated into the model to provide survival estimates that accounted for these factors. In the North Santiam River between Minto Dam and the Bennett Dam complex, a distance of 37.2 kilometers, survival was estimated to be 0.844 (95-percent confidence interval 0.795–0.893). The survival estimate for the 203.7 kilometer reach between the Bennett Dam complex and Portland, Oregon, was 0.279 (95-percent confidence interval 0.234–0.324), and included portions of the North Santiam, Santiam, and Willamette Rivers. The cumulative survival estimate in the 240.9 kilometer reach from the Minto Dam tailrace to Portland was 0.236 (95-percent confidence interval 0.197–0.275).

    IntroductionThis is a 1:24,000-scale geologic map of the Vancouver and Orchards quadrangles and parts of the Portland and Mount Tabor quadrangles in the States of Washington and Oregon. The map area is within the Portland Basin and includes most of the city of Vancouver, Washington; parts of Clark County, Washington; and a small part of northwestern Multnomah County, Oregon. The Columbia River flows through the southern part of the map area, generally forming the southern limit of mapping. Mapped Quaternary geologic units include late Pleistocene cataclysmic flood deposits, eolian deposits, and alluvium of the Columbia River and its tributaries. Older deposits include Miocene to Pleistocene alluvium from an ancestral Columbia River. Regional geologic structures are not exposed in the map area but are inferred from nearby mapping.

  17. Storm runoff as related to urbanization based on data collected in Salem and Portland, and generalized for the Willamette Valley, Oregon

    Storm runoff as related to urbanization is defined by a series of regression equations for Salem and for the Willamette Valley, Oregon. In addition to data from 17 basins monitored in the Salem area, data from 24 basins gaged in a previous study in Portland, Oregon - Vancouver, Washington were used defining the Willamette Valley equations. Basins used to define equations ranged in size from 0.2 to 26 square miles. Rainfall intensity varied from 1.8 to 2.2 inches for the 6 hour, 0.2 exceedance probability. Sensitivity analyses of equations indicate that urbanization of an undeveloped basin can increase peak discharge more than three times and almost double runoff volume. Much of Portland and Vancouver are located on porous river terraces where dry wells are used to shunt runoff. Much of East Salem is located on previously farmed land where drain tiles used to dewater soils still connect directly to streams. (USGS)

  20. Vertical-Axis Rotations Within Columbia River Basalt Flows Define a Sharp Eastern Boundary of the Coast Range Block with Potentially Increased Seismic Risk for Portland, Oregon

    Paleomagnetic analysis of the Miocene Columbia River Basalt Group (CRBG) in the northern Willamette Valley of Oregon was undertaken as part of a larger mapping and hydrogeologic investigation of the CRBG's internal stratigraphy and structure. Differences in paleomagnetic directions between flows due to geomagnetic reversals and paleosecular variation, in combination with geochemical data, provide the most reliable means of flow identification. In addition, vertical-axis rotations between CRBG sites in the Portland area and sampling localities within the same flow units on the relatively stable Columbia Plateau were calculated. Clockwise rotations for sites within the northern Willamette Valley are remarkably consistent and have a weighted mean of 29°±3° (N=94). Available paleomagnetic data from CRBG sites along the Oregon coast at Cape Lookout (19°±22°, N=4) and Cape Foulweather (29°±18°, N=4) show similar results. East of the Portland Hills fault zone along the Columbia River Gorge, however, clockwise rotations are much less averaging 12°±3° (N=15). North of Portland, the CRBG rotational values drop abruptly from ~29° to 6°±17° (N=3) across an unnamed fault near Woodland, WA, identified using aeromagnetic data; to the south, the values drop from ~29° to 18°±3° (N=6) across the Mt. Angel-Gales Creek fault zone east of Salem, OR. The eastern boundary of the Oregon Coast Range block is thus defined by three offset NW-trending fault segments, with the offsets corresponding to the Portland and Willamette pull-apart basins. North of the Coast Range block's northern boundary, which is roughly coincident with the Columbia River, CRBG rotations also are about half that (15°±3°, N=15) found within the block. Northward movement and clockwise rotation of the Oregon Coast Range block have previously been modeled as decreasing continuously eastward to the Columbia Plateau. Our new paleomagnetic data indicate an abrupt step down of rotational values by

    Portland's Active Living by Design focused on two communities facing different active living challenges: Lents is an urban, lower-income community with poor bicycle/pedestrian and park infrastructure, and Damascus is a semirural community expected to see extensive urban growth in the next 30 years. Pilot projects were implemented in a semirural community with considerable growth potential, and a lower-income, ethnically diverse urban neighborhood. The partners' primary active-living goals included: prepare and sustain a network of public health, planning, community, and policymaking partners; affect urban planning and policy decisions to influence built-environment changes in Portland neighborhoods; and support active-living program and promotion partners. Partners have focused on building capacity for cross-disciplinary collaboration and leading strategic efforts toward policy, environmental, and social change. Partners have been engaged in policy advocacy and strategic campaign initiatives, as well as community program efforts that bring active living opportunities to underserved neighborhoods. The ALbD community-action model served as a valuable tool for organizing intervention activities and bringing diverse partners together under a shared vision. Public health professionals engaged in land-use and transportation collaborations must strike a balance between becoming experts in technical aspects of new disciplines and addressing a wide range of active living determinants. Embracing a healthy community agenda can create fruitful new partnerships and increase the impact on systemic change. Many of the partnerships' collaborative efforts to encourage healthy communities through policy, environmental, and social change have been largely successful and can serve as a model for other communities.

  2. The Production of Organic Nitrates in Portland, Oregon and the Columbia River Gorge

    NASA Astrophysics Data System (ADS)

    Neill, Holly Ann

    This work studied the production of aerosol-phase organic nitrates in both Portland and the Columbia River Gorge (CRG). Ozone and NO x species were investigated for correlation with organic nitrate aerosol, as they function as precursors to the production of organic nitrates. These ambient gas-phase measurements were collected in the same locations as high-volume (Hi-Vol) filters samples, in an urban and rural gorge setting to investigate correlations at the origin of the pollution plume and downwind. A novel Soxhlet extraction method for Hi-Vol filters was developed based on literature and EPA standard methods. Analysis for nitrate production was done by segregating data based on times when the wind blew out of Portland and down the CRG versus times when flow was not westerly. Filters were then compared to ambient gas-phase measurements and derived NO3 radical production rates to look for trends. Wind direction had a strong influence on the concentrations of precursor molecules in the CRG. On days with a westerly wind direction into the gorge, concentrations of the measure aerosol organic nitrates were similar at both sides. This suggests some contribution of a broader regional production of organic nitrates. There was some correlation between the production rate of NO3 radicals and the measured organic nitrate aerosol, suggesting a role for NO3 + VOC production of organic nitrates that later partition to the aerosol phase. This information will better illuminate the fate of nitrogen downwind of pollution sources. The information will also help to create a better understanding of the way topography and meteorological conditions can influence the flow of pollution. Understanding the downwind oxidative chemistry that happens in the CRG would better support both pollution prevention and mitigation efforts..

    Reliable information on the configuration of the water table in the Portland metropolitan area is needed to address concerns about various water-resource issues, especially with regard to potential effects from stormwater injection systems such as UIC (underground injection control) systems that are either existing or planned. To help address these concerns, this report presents the estimated depth-to-water and water-table elevation maps for the Portland area, along with estimates of the relative uncertainty of the maps and seasonal water-table fluctuations. The method of analysis used to determine the water-table configuration in the Portland area relied on water-level data from shallow wells and surface-water features that are representative of the water table. However, the largest source of available well data is water-level measurements in reports filed by well constructors at the time of new well installation, but these data frequently were not representative of static water-level conditions. Depth-to-water measurements reported in well-construction records generally were shallower than measurements by the U.S. Geological Survey (USGS) in the same or nearby wells, although many depth-to-water measurements were substantially deeper than USGS measurements. Magnitudes of differences in depth-to-water measurements reported in well records and those measured by the USGS in the same or nearby wells ranged from -119 to 156 feet with a mean of the absolute value of the differences of 36 feet. One possible cause for the differences is that water levels in many wells reported in well records were not at equilibrium at the time of measurement. As a result, the analysis of the water-table configuration relied on water levels measured during the current study or used in previous USGS investigations in the Portland area. Because of the scarcity of well data in some areas, the locations of select surface-water features including major rivers, streams, lakes, wetlands, and

    Over a 1.5-year period, water-quality data were collected for seven small drainage basins in urban aeas of Portland, Oreg. Analysis of the data followed three approaches. First, the constituent concentrations were analyzed. Average concentrations of suspended sediment, settleable solids, and fecal coliform bacteria generally exceeded levels expected for secondary waste-treatment plant effluent, whereas biochemical oxygen demand concentrations were lower than expected. The second analytical approach established correlations and bivariate regression relationships between constituents for individual storms in each basin, for all storms in each basin, and for all storms in all basins. Generally, correlation coefficients decreased when progressing from data for individual storms in each basin, to data for all storms in each basin, to data for all storms in all basins. In the third approach, storm yields for 10 constituents were related to basin and precipitation characteristics by use of multiple-linear-regression techniques. Storm yields for suspended sediment varied by about four orders of magnitude. Generally, results of the multiple-regression analysis indicated that variations in storm yields were highly dependent on precipitation characteristics, with total rainfall of the storm frequently explaining most of the variation of the dependent variable.

  6. Storm runoff as related to urbanization in the Portland, Oregon-Vancouver, Washington Area

    1980-01-01

    A series of equations was developed to provide a better method of determining flood frequencies in the Portland-Vancouver urban area than is now available. The resulting regression equations can be used to compute peak discharge and storm runoff with a standard error of estimate of approximately 30 percent. Basins used to define the regression equations ranged in size from 0.2 to 26 square miles. Those physical basin parameters that proved to be significant are: drainage area, effective impervious area, storage, rainfall intensity, basin slope, and soil infiltration. The equations indicate that total urbanization of an undeveloped basin can increase peak discharge as much as 3? times and almost double the volume of storm runoff. Impervious area, as delineated by mapping techniques, proved to be an inadequate physical parameter for use in the regression equations because builders and planners have devised many methods of routing storm runoff from impervious areas to the main channel (in effect, speeding up or slowing down the response to the storm). In some parts of the study area, storm runoff was diverted into dry wells and never entered the main channel. To define the effect of this rerouting, the digital model was used to find an effective impervious area that would 'best fit' the rainfall-runoff data. Field estimates to verify the effectiveness of the impervious area for two of the basins showed that optimizations were within 20 percent of those shown by the digital model. Users of these data who may find the effective impervious area a difficult, expensive, and time-consuming parameter to obtain have an alternative. The combination of land-use type I (parks, forests, and vacant lots) and Type II (agriculture) proved to be an excellent inverse indicator of impervious area. Land-use types I and II, coupled with the street-gutter density, an indication of effective routing, provide the user with alternative indices of urbanization.

    Fishermen, marine researchers, educators, plastics manufacturers and government representatives--more than 80 in all--met in Portland, Oregon February 9-11, 1988, for 'Oceans of Plastic,' a workshop to address problems caused by fisheries-generated plastic debris and derelict fishing gear. The workshop examined ways to reduce marine plastic debris and explained new laws intended to halt plastic pollution in the ocean. The Portland workshop was planned to accomplish the following objectives: Contribute to the understanding of fisheries-generated marine plastic debris, investigate ways to reduce the amount of fisheries-generated marine debris, identify effective ways--including possible incentives--to reduce derelict fishing gear, and contribute to the nation's marine debris education program.

    Students from the Department of Geology at Portland State University paired up with the Oregon Health Authority to better understand radon gas values in homes of the Portland metropolitan area. This study focuses on radon values collected by continuous radon measurement (CRM) machines, taken by local radon testing companies. The local companies participating in this study include Alpha Environmental Services, Inc., Cascade Radon, Environmental Works, The House Detectives, LLC, and Soil Solutions Environmental Services, Inc. In total, 2491 radon readings spanning across 77 zip codes were collected from local companies in the Portland metropolitan area. The maximum value, average value, percentage of homes greater than 4 pCi/L and total rank sum was calculated and used to determine the overall radon potential for each zip code (Burns et al., 1998). A list and four maps were produced showing the results from each category. Out of the total records, 24 zip codes resulted in high radon potential and the average reading for the entire Portland Metropolitan area was 3.7 pCi/L. High potential zip codes are thought to be a result of sand and gravel (Missoula Flood deposits) and faults present in the subsurface. The CRM data was compared with both long-term and short-term data provided by the Oregon Health Authority to validate radon potentials in each zip code. If a home is located in a zip code with high or moderate radon potential across two types of data sets, it is recommended that those homes be tested for radon gas.

    The NL/Gould National Priorities List (NPL) site is situated near the banks of the Williamette River in the Doane Lake area of Portland, Oregon. Past lead reclamation operations and disposal practices on and around the NL/Gould facility have resulted in the contamination of on-site surface and subsurface soil, lake sediment, and ground water with lead, arsenic, cadmium, and chromium. The NL/Gould NPL site currently poses a threat to public health as a result of the potential for direct ingestion of lead-contaminated soil and direct contact exposure to lead-contaminated soil, sediment, and ground water.

  2. The Boring Volcanic Field of the Portland-Vancouver area, Oregon and Washington: tectonically anomalous forearc volcanism in an urban setting

    More than 80 small volcanoes are scattered throughout the Portland-Vancouver metropolitan area of northwestern Oregon and southwestern Washington. These volcanoes constitute the Boring Volcanic Field, which is centered in the Neogene Portland Basin and merges to the east with coeval volcanic centers of the High Cascade volcanic arc. Although the character of volcanic activity is typical of many monogenetic volcanic fields, its tectonic setting is not, being located in the forearc of the Cascadia subduction system well trenchward of the volcanic-arc axis. The history and petrology of this anomalous volcanic field have been elucidated by a comprehensive program of geologic mapping, geochemistry, 40Ar/39Ar geochronology, and paleomag-netic studies. Volcanism began at 2.6 Ma with eruption of low-K tholeiite and related lavas in the southern part of the Portland Basin. At 1.6 Ma, following a hiatus of ~0.8 m.y., similar lavas erupted a few kilometers to the north, after which volcanism became widely dispersed, compositionally variable, and more or less continuous, with an average recurrence interval of 15,000 yr. The youngest centers, 50–130 ka, are found in the northern part of the field. Boring centers are generally monogenetic and mafic but a few larger edifices, ranging from basalt to low-SiO2 andesite, were also constructed. Low-K to high-K calc-alkaline compositions similar to those of the nearby volcanic arc dominate the field, but many centers erupted magmas that exhibit little influence of fluids derived from the subducting slab. The timing and compositional characteristics of Boring volcanism suggest a genetic relationship with late Neogene intra-arc rifting.

    The coupled processes of climate change and urbanization pose challenges for water resource management in cities worldwide. Comparing the vulnerabilities of water systems in Phoenix, Arizona and Portland, Oregon, this paper examines (1) exposures to these stressors, (2) sensitivities to the associated impacts, and (3) adaptive capacities for responding to realized or anticipated impacts. Based on a case study and survey-based approach, common points of vulnerability include: rising exposures to drier, warmer summers, and suburban growth; increasing sensitivities based on demand hardening; and limited capacities due to institutional and pro-growth pressures. Yet each region also exhibits unique vulnerabilities. Comparatively, Portland shows: amplified exposures to seasonal climatic extremes, heightened sensitivity based on less diversified municipal water sources and policies that favor more trees and other irrigated vegetation, and diminished adaptive capacities because of limited attention to demand management and climate planning for water resources. Phoenix exhibits elevated exposure from rapid growth, heightened sensitivities due to high water demands and widespread increases in residential and commercial uses, and limited adaptive capacities due to weak land use planning and "smart growth" strategies. Unique points of vulnerability suggest pathways for adapting to urban-environmental change, whether through water management or land planning. Greater coordination between the land and water sectors would substantially reduce vulnerabilities in the study regions and beyond.

    A high-resolution gravity survey through the Tualatin Mountains (Portland Nills) west of downtown Portland exhibits evidence of faults previously identified from surface geologic and aeromagnetic mapping. The gravity survey was conducted in 1996 along the 4.5-km length of a twin-bore tunnel, then under construction and now providing light-rail service between downtown Portland and communities west of the Portland Hills. Gravitational attraction gradually increases from west to east inside the tunnel, which reflects the tunnel's location between low-density sedimentary deposits of the Tualatin basin to the west and high-density, mostly concealed Eocene basalt to the east. Superimposed on this gradient are several steplike anomalies that we interpret as evidence for faulted contacts between rocks of contrasting density. The largest of these anomalies occurs beneath Sylvan Creek, where a fault had previously been mapped inside the tunnel. Another occurs 1200 m from the west portal, at the approximate intersection of the tunnel with an aeromagnetic anomaly associated with the Sylvan fault (formerly called the Oatfield fault). Lithologic cross sections based on these gravity data show that the steplike anomalies are consistent with steeply dipping reverse faults, although strike-slip displacements also may be important. Three gravity lows correspond with topographic lows directly overhead and may reflect zones of shearing. Several moderate earthquakes (M ??? 3.5) occurred near the present-day location of the tunnel in 1991, suggesting that some of these faults or other faults in the Portland Hills fault zone are seismically active.

    Seismic activity in the Portland-Vancouver metropolitan area may be associated with various mapped faults that locally offset volcanic basement of Eocene age and younger. This volcanic basement is concealed in most places by young deposits, vegetation, and urban development. The US Geological Survey conducted an aeromagnetic survey in September 1992 to investigate the extent of these mapped faults and possibly to help identify other seismic and volcanic hazards in the area.

    As part of the evaluations conducted at Detroit Dam, we continued to refine and improve methods for monitoring fish movements in the Willamette River. The goal was to develop stable, cost-effective, long-term monitoring arrays suitable for detection of any Juvenile Salmon Acoustic Telemetry System (JSATS)-tagged fish in the Willamette River. These data then could be used to estimate timing, migration rates, and survival of JSATS-tagged fish from various studies in the Willamette River Basin. The challenge, however, is that acoustic telemetry generally performs poorly in shallow, turbulent water, like that found in the Willamette River. We successfully designed, deployed, and maintained a series of monitoring sites near the Oregon cities of Salem, Wilsonville, and Portland. In the spring, detection probabilities at these sites ranged from 0.900 to 1.000. In the fall, the detection probabilities decreased and ranged from 0.526 to 1.000. The lower detection probabilities, particularly at the Salem site (0.526), were owing to loss of data caused by abnormally high flows as well as the 2013 Federal government shutdown, which prevented us from servicing the equipment. The monitoring sites that we installed seem to be robust and enable the efficient use of acoustic-tagged fish for studies of migration or survival in the Willamette River and similar environments.

    This case study is about the politics of incorporating active-living elements into a concept plan for a new community of about 68,000 people on the edge of the Portland, Oregon, metropolitan area. Development on the rural-urban fringe is ongoing in metropolitan areas around the United States. In this article, we evaluate the product of the concept-planning process from the standpoint of the extent to which environmental elements conducive to active living were included. We also analyze four issues in which challenges to the incorporation of active-living features surfaced: choices related to transportation facilities, the design and location of retail stores, the location of schools and parks, and the location of a new town center. Overall, the Damascus/Boring Concept Plan positions the area well to promote active living. Analyses of the challenges that emerged yielded lessons for advocates regarding ways to deal with conflicts between facilitating active living and local economic development and related tax-base concerns and between active-living elements and school-district planning autonomy as well as the need for advocates to have the capacity to present alternatives to the usual financial and design approaches taken by private- and public-sector investors.

At least six or seven had peak discharges of >6.5 x 106 m3/s, and at least one flood had a peak discharge of >10 x 106 m3/s, a value consistent with earlier results from near Wallula Gap, but better defined because of the strong hydraulic controls imposed by critical flow at constrictions near Crown and Mitchell Points in the Columbia River Gorge. Stratigraphy and geomorphic position, combined with 25 radiocarbon ages and the widespread occurrence of the ca. 13 ka (radiocarbon years) Mount St. Helens set-S tephra, show that most if not all the Missoula flood deposits exposed in the study area were emplaced after 19 ka (radiocarbon years), and many were emplaced after 15 ka. More than 13 floods perhaps postdate ca. 13 ka, including at least two with discharges of >6 x 106 m3/s. From discharge and stratigraphic relationships upstream, we hypothesize that the largest flood in the study reach resulted from a Missoula flood that predated blockage of the Columbia River valley by the Cordilleran ice sheet. Multiple later floods, probably including the majority of floods recorded by fine- and coarse-grained deposits in the study area, resulted from multiple releases of glacial Lake Missoula that spilled into a blocked and inundated Columbia River valley upstream of the Okanogan lobe and were shunted south across the Channeled Scabland.

  16. Case studies of the legal and institutional obstacles and incentives to the development of small-scale hydroelectric power: Bull Run, Portland, Oregon

    SciTech Connect

    1980-05-01

    The National Conference of State Legislatures' Small-Scale Hydroelectric Policy Project is designed to assist selected state legislatures in looking at the benefits that a state can derive from the development of small-scale hydro, and in carrying out a review of state laws and regulations that affect the development of the state's small-scale hydro resources. The successful completion of the project should help establish state statutes and regulations that are consistent with the efficient development of small-scale hydro. As part of the project's work with state legislatures, seven case studies of small-scale hydro sites were conducted to provide a general analysis and overview of the significant problems and opportunities for the development of this energy resource. The case study approach was selected to expose the actual difficulties and advantages involved in developing a specific site. Such an examination of real development efforts will clearly reveal the important aspects about small-scale hydro development which could be improved by statutory or regulatory revision. Moreover, the case study format enables the formulation of generalized opportunities for promoting small-scale hydro based on specific development experiences. The case study for small-scale hydro power development at the City of Portland's water reserve in the Bull Run Forest is presented with information included on the Bull Run hydro power potential, current water usage, hydro power regulations and plant licensing, technical and economic aspects of Bull Run project, and the environmental impact.

  19. Water-discharge determinations for the tidal reach of the Willamette River from Ross Island Bridge to Mile 10.3, Portland, Oregon

    Dempster, G.R.; Lutz, Gale A.

    1968-01-01

    Water-discharge, velocity, and slope variations for a 3.7-mile-Iong tidal reach of the Willamette River at Portland, Oreg., were defined from discharge measurements and river stage data collected between July 1962 and January 1965. Observed water discharge during tide-affected flows, during floods, and during backwater from the Columbia River and recorded stages at each end of the river reach were used to determine water discharge from two mathematical models. These models use a finite-difference method to solve the equations of moderately unsteady open-channel streamflow, and discharges are computed by an electronic digital computer. Discharges computed by using the mathematical models compare satisfactorily with observed discharges, except during the period of backwater from the annual flood of the Columbia River. The flow resistance coefficients used in the models vary with discharge; for one model, the coefficients for discharges above 30,000 cfs (cubic feet per second) are 12 and 24 percent less than the coefficient used for discharges below 30,000 cfs. Daily mean discharges were determined by use of one mathematical model for approximately two-thirds of the water year, October 1963 through September 1964. Agreement of computed with routed daily mean discharges is fair; above 30,000 cfs, average differences between the two discharges are about 10 percent, and below 30,000 cfs, computed daily discharges are consistently greater (by as much as 25 percent) than routed discharges. The other model was used to compute discharges for the unusually high flood flows of December 1964.

    2011-06-01

    Geomorphic landscape development in the pre-Holocene ancestral Columbia River Valley (1-5 km width) in the Portland forearc basin (~ 50 km length) is established from depositional sequences, which pre-date and post-date the glacial Lake Missoula floods. The sequences are observed from selected borehole logs (150 in number) and intact terrace soil profiles (56 in number) in backhoe trenches. Four sequences are widespread, including (1) a vertically aggraded Pleistocene alluvial plain, (2) a steep sided valley that is incised (125-150 m) into the Pleistocene gravel plain, (3) Missoula flood terraces (19-13 ka) abandoned on the sides of the ancestral valley, and (4) Holocene flooding surfaces (11-8 ka) buried at 70-30 m depth in the axial Columbia River Valley. Weathering rims and cementation are used for relative dating of incised Pleistocene gravel units. Soil development on the abandoned Missoula flood terraces is directly related to terrace deposit lithology, including thin Bw horizons in gravel, irregular podzols in sand, and multiple Bw horizons in thicker loess-capping layers. Radiocarbon dating of sand and mud alluvium in the submerged axial valley ties Holocene flooding surfaces to a local sea level curve and establishes Holocene sedimentation rates of 1.5 cm year- 1 during 11-9 ka and 0.3 cm year- 1 during 9-0 ka. The sequences of Pleistocene gravel aggradation, river valley incision, cataclysmic Missoula flooding, and Holocene submergence yield complex geomorphic landscapes in the ancestral lower Columbia River Valley.

  1. A Cooking Intervention to Increase Vegetable Consumption by Parents With Children Enrolled in an Early Head Start Home Visiting Program: A Pilot Study in Portland, Oregon, 2013–2014

    Introduction Cooking interventions may improve diet quality. Most cooking interventions are delivered in group settings. Home visiting programs may be an appropriate mechanism for delivering such interventions to low-income families with young children. We conducted a pilot study to test the feasibility of using a cooking intervention delivered by home visitors to improve attitudes and behaviors related to vegetable consumption by low-income parents with children enrolled in a home visiting program. Methods We invited 121 parents with children enrolled in an Early Head Start Home Visiting program in Portland, Oregon, to participate. During 2013–2014, each month for 8 months, home visitors (n = 14) implemented 1 cooking activity plus 1 complementary activity focused on 12 vegetables. We collected pre- and post-intervention data on participants’ cooking confidence and whether they tried and liked the selected vegetables. We also measured fidelity to protocol and home visitors’ perception of intervention usability. Results Of 104 participants, 58 provided pre- and post-intervention data. We observed a significant increase in confidence in baking, roasting or grilling vegetables; cooking 6 of 10 vegetables; and trying 7 of 12 vegetables. Nearly all respondents participated in the monthly cooking activity (96%) and complementary activity (94%). Twelve of 14 home visitors reported that the intervention was acceptable, feasible, and easy to understand, and needed systems supports to implement. Conclusion Cooking interventions may be a feasible approach to improving attitudes and behaviors related to vegetable consumption by low-income families with young children. Additional research is needed to assess the impact of such interventions on vegetable consumption. PMID:28005529

  2. Age-Friendly Portland: a university-city-community partnership.

    Neal, Margaret B; DeLaTorre, Alan K; Carder, Paula C

    2014-01-01

    This article addresses the question of how creating an age-friendly city has come to be an important policy and planning issue in Portland, Oregon. In 2006, researchers from Portland State University's Institute on Aging examined the meanings of age friendliness among a broad range of participants in Portland, Oregon. The research was conducted in conjunction with the World Health Organization's (WHO) Age-Friendly Cities project and followed the completion of two earlier non-WHO-related projects. The city of Portland, through the Institute on Aging, was one of nine original members to apply for and be accepted into the WHO Global Network of Age-Friendly Cities and Communities. An Age-Friendly Portland Advisory Council was formed to guide the development of an action plan, monitor progress over time, and suggest additional research. To understand how Portland's age-friendly policy effort has developed over time, we use Kingdon's (1984) agenda-setting framework to explain how the policy problem was formulated, how solutions were developed, and the influence of local politics. The policy actors, including individuals and organizations working within and outside of government, are described. The Portland experience provides a case study that other cities, especially those with a strong commitment to community-engaged urban planning, may find useful as they develop age-friendly initiatives.

The Forum provides an opportunity for states and compacts to share information with one another and to exchange views with officials of federal agencies. LLW Forum participants include representatives from regional compacts, designated host states, unaffiliated states, and states with currently-operating low-level radioactive waste facilities. This quarterly meeting was held April 25-27, 1994 and activities during the first quarter of 1994 are detailed..

  14. Crystal structure of the intraflagellar transport complex 25/27

    PubMed Central

    Bhogaraju, Sagar; Taschner, Michael; Morawetz, Michaela; Basquin, Claire; Lorentzen, Esben

    2011-01-01

    The cilium is an important organelle that is found on many eukaryotic cells, where it serves essential functions in motility, sensory reception and signalling. Intraflagellar transport (IFT) is a vital process for the formation and maintenance of cilia. We have determined the crystal structure of Chlamydomonas reinhardtii IFT25/27, an IFT sub-complex, at 2.6 Å resolution. IFT25 and IFT27 interact via a conserved interface that we verify biochemically using structure-guided mutagenesis. IFT27 displays the fold of Rab-like small guanosine triphosphate hydrolases (GTPases), binds GTP and GDP with micromolar affinity and has very low intrinsic GTPase activity, suggesting that it likely requires a GTPase-activating protein (GAP) for robust GTP turnover. A patch of conserved surface residues contributed by both IFT25 and IFT27 is found adjacent to the GTP-binding site and could mediate the binding to other IFT proteins as well as to a potential GAP. These results provide the first step towards a high-resolution structural understanding of the IFT complex. PMID:21505417

  19. Portland outlines waste reduction program

    SciTech Connect

    Rifer, W.

    1986-09-01

    Plans for solid waste systems must reflect the preferences and values of the community they serve. The Metropolitan Service District (Metro), an elected regional government for the Portland (Oregon) area, has launched an ambitious effort to reduce the amount of solid waste being landfilled. The current solid waste system in the Portland area consists of: (1) a healthy private recycling program which is achieving a nearly 22% reduction of waste, (2) a private garbage collection system which is regulated by local governments (half franchised and half competitive), and (3) a regional disposal system operated by Metro which relies on landfilling. The system envisioned by the Metro Waste Reduction Program will add significant diversity to the disposal system, and will, by necessity, involve the collection, recycling and disposal systems in a coordinated partnership. The total volume of waste to be handled through the Waste Reduction Program is approximately 962,000 tons/year. Currently, 755,000 tons/year are disposed of in a landfill and the remainder is recycled through various methods.

  19. Early chiropractic education in Oregon

    Keating, Joseph C

    2002-01-01

    Chiropractic education in the northwestern United States has its origins in the Marsh School & Cure in 1904. Most of the early schools were located in Portland, Oregon, including the D.D. Palmer College of Chiropractic (1908-1910), and several of these had merged by 1912 or 1913 to form the Pacific Chiropractic College, forerunner of today's Western States College. The latter was organized as a non-profit institution during the Great Depression, and struggled not only to survive but to create a higher standard. The early broad-scope of chiropractic training in the state probably encouraged the liberal scope of practice enjoyed in Oregon to this day.

    At 5:34 a.m. on March 25, 1993, much of northwestern Oregon and southwestern Washington was shaken by one if the largest historic earthquakes ever observed in the region. The Richter magnitude 5.6 earthquake occurred near the small town of Scotts Mills, 48 km south of Portland, Oregon. The March 25 earthquake was felt over a large part of the Pacific Northwest extending from Seattle, Washington, in the north to the town of Roseburg in southern Oregon. Due in large part to the moderate size of the event and its location in a rural setting, only minor injuries occurred, principally from falling objects and broken glass.

    Schott, J.J.; Charpentier, F.; Peltier, S.

    1995-11-01

    Long QT syndrome (LQTS) is a heterogeneous inherited disorder causing syncope and sudden death from ventricular arrhythmias. A first locus for this disorder was mapped to chromosome 11p15.5. However, locus heterogeneity has been demonstrated in several families, and two other loci have recently been located on chromosomes 7q35-36 and 3p21-24. We used linkage analysis to map the locus in a 65-member family in which LQTS was associated with more marked sinus bradycardia than usual, leading to sinus node dysfunction. Linkage to chromosome 11p15.5, 7q35-36, or 3p21-24 was excluded. Positive linkage was obtained for markers located on chromosome 4q25-27. A maximal LOD score of 7.05 was found for marker D4S402. The identification of a fourth locus for LQTS confirms its genetic heterogeneity. Locus 4q25-27 is associated with a peculiar phenotype within the LQTS entity. 42 refs., 4 figs., 3 tabs.

  9. Iterated transportation simulations for Dallas and Portland

    Nagel, K.; Simon, P.; Rickert, M.; Esser, J.

    1998-09-02

    The goal of the TRansportation ANalysis and SIMulation System (TRANSIMS) is to combine the most important aspects of human decision-making related to transportation, from activities planning (sleep, work, eat, shop,...) via modal and route planning to driving, into a single, consistent methodological and software framework. This is meant to combine the functionalities of activities-based travel demand generation, modal choice and route assignment, and micro-simulation. TRANSIMS attempts to employ advanced methodologies in all these modules. Yet, it is probably the overall framework that is the most important part of this attempt. It is, for example, possible to replace the TRANSIMS microsimulation by another micro-simulation that uses the same input and generates the same output. TRANSIMS uses specific regions as examples in order to ensure that the technology is rooted in the real world. Until about the middle of 1997, an approximately five miles by five miles area in Dallas/Texas was used. Since then, TRANSIMS has moved to using data from Portland/Oregon; a case study for this region is planned to be completed by the end of the year 2000. In this paper the authors give short descriptions of these projects and give references to related publications.

  10. Portland Water Fluoridation: A Newspaper Analysis.

    Bianchi, Allison; Bergren, Martha Dewey; Lewis, Patricia Ryan

    2017-03-01

    Portland, Oregon is the largest city in the United States without community water fluoridation (CWF). A newspaper analysis was conducted of the failed 2013 CWF campaign to evaluate anti-fluoridation and pro-fluoridation messaging provided by newspapers during the campaign. News content was categorized by type and slant (pro-fluoridation, anti-fluoridation, or neutral) and 34 variables were tabulated (23 anti-fluoridation, 11 pro-fluoridation). Results showed overall messaging was slightly pro-fluoridation, as compared to anti-fluoridation or neutral content (35%, 32%, and 33% respectively). Editorial content was 85% pro-fluoridation and 15% anti-fluoridation. The most frequent anti-fluoridation variables were alternatives to water fluoridation, mass/forced medication and concerns about the political process. Conversely, tooth decay and social justice were the most commonly cited pro-fluoridation variables. Newspapers can be influential in shaping public policy opinions in the fight for community water fluoridation. © 2016 Wiley Periodicals, Inc.

    2009-01-01

    The Carlton, Oregon, 7.5-minute quadrangle is located in northwestern Oregon, about 35 miles (57 km) southwest of Portland. It encompasses the towns of Yamhill and Carlton in the northwestern Willamette Valley and extends into the eastern flank of the Oregon Coast Range. The Carlton quadrangle is one of several dozen quadrangles being mapped by the U.S. Geological Survey (USGS) and the Oregon Department of Geology and Mineral Industries (DOGAMI) to provide a framework for earthquake- hazard assessments in the greater Portland, Oregon, metropolitan area. The focus of USGS mapping is on the structural setting of the northern Willamette Valley and its relation to the Coast Range uplift. Mapping was done in collaboration with soil scientists from the National Resource Conservation Service, and the distribution of geologic units is refined over earlier regional mapping (Schlicker and Deacon, 1967). Geologic mapping was done on 7.5-minute topographic base maps and digitized in ArcGIS to produce ArcGIS geodatabases and PDFs of the map and text. The geologic contacts are based on numerous observations and samples collected in 2002 and 2003, National Resource Conservation Service soils maps, and interpretations of 7.5-minute topography. The map was completed before new, high-resolution laser terrain mapping was flown for parts of the northern Willamette Valley in 2008.

  19. Simple queueing model applied to the city of Portland

    SciTech Connect

    Simon, P.M.; Nagel, K. |

    1998-07-31

    The authors present a simple traffic micro-simulation model that models the effects of capacity cut-off, i.e. the effect of queue built-up when demand is exceeding capacity, and queue spillback, i.e. the effect that queues can spill back across intersections when a congested link is filled up. They derive the model`s fundamental diagrams and explain it. The simulation is used to simulate traffic on the emme/2 network of the Portland (Oregon) metropolitan region (20,000 links). Demand is generated by a simplified home-to-work assignment which generates about half a million trips for the AM peak. Route assignment is done by iterative feedback between micro-simulation and router. Relaxation of the route assignment for the above problem can be achieved within about half a day of computing time on a desktop workstation.

    2009-01-01

    Metropolitan Portland, Oregon, USA, lies within a small Neogene to Holocene basin in the forearc of the Cascadia subduction system. Although the basin owes its existence and structural development to its convergent-margin tectonic setting, the stratigraphic architecture of basin-fill deposits chiefly reflects its physiographic position along the lower reaches of the continental-scale Columbia River system. As a result of this globally unique setting, the basin preserves a complex record of aggradation and incision in response to distant as well as local tectonic, volcanic, and climatic events. Voluminous flood basalts, continental and locally derived sediment and volcanic debris, and catastrophic flood deposits all accumulated in an area influenced by contemporaneous tectonic deformation and variations in regional and local base level.

  8. Simple Queueing Model Applied to the City of Portland

    NASA Astrophysics Data System (ADS)

    Simon, Patrice M.; Esser, Jörg; Nagel, Kai

    We use a simple traffic micro-simulation model based on queueing dynamics as introduced by Gawron [IJMPC, 9(3):393, 1998] in order to simulate traffic in Portland/Oregon. Links have a flow capacity, that is, they do not release more vehicles per second than is possible according to their capacity. This leads to queue built-up if demand exceeds capacity. Links also have a storage capacity, which means that once a link is full, vehicles that want to enter the link need to wait. This leads to queue spill-back through the network. The model is compatible with route-plan-based approaches such as TRANSIMS, where each vehicle attempts to follow its pre-computed path. Yet, both the data requirements and the computational requirements are considerably lower than for the full TRANSIMS microsimulation. Indeed, the model uses standard emme/2 network data, and runs about eight times faster than real time with more than 100 000 vehicles simultaneously in the simulation on a single Pentium-type CPU. We derive the model's fundamental diagrams and explain it. The simulation is used to simulate traffic on the emme/2 network of the Portland (Oregon) metropolitan region (20 000 links). Demand is generated by a simplified home-to-work destination assignment which generates about half a million trips for the morning peak. Route assignment is done by iterative feedback between micro-simulation and router. An iterative solution of the route assignment for the above problem can be achieved within about half a day of computing time on a desktop workstation. We compare results with field data and with results of traditional assignment runs by the Portland Metropolitan Planning Organization. Thus, with a model such as this one, it is possible to use a dynamic, activities-based approach to transportation simulation (such as in TRANSIMS) with affordable data and hardware. This should enable systematic research about the coupling of demand generation, route assignment, and micro

    To mitigate climate change, governments at multiple levels are developing policies to decrease anthropogenic carbon dioxide (CO2) emissions. The City of Portland (Oregon) and Multnomah County have adopted a Climate Action Plan with a stated goal of reducing emissions to 80% below 1990 levels by 2050. The transportation sector alone accounts for about 40% of total emissions in the Portland metropolitan area. Here we show a new street-level model of on-road mobile CO2 emissions for the Portland, OR metropolitan region. The model uses hourly traffic counter recordings made by the Portland Bureau of Transportation at 9,352 sites over 21 years (1986-2006), augmented with freeway loop detector data from the Portland Regional Transportation Archive Listing (PORTAL) transportation data archive. We constructed a land use regression model to fill in traffic network gaps with traffic counts as the dependent variable using GIS data such as road class (32 categories) and population density. The Environmental Protection Agency (EPA) MOtor Vehicle Emission Simulator (MOVES) model was used to estimate transportation CO2 emissions. The street-level emissions can be aggregated and gridded and used as input to atmospheric transport models for comparison with atmospheric measurements. This model also provides an independent assessment of top-down inventories that determine emissions from fuel sales, while being an important component of our ongoing effort to assess the effectiveness of emission mitigation strategies at the urban scale.

  3. Special Session on Internal Dose at HPS Meeting in Portland

    Strom, Daniel J.

    2007-09-22

    In October 2006, the most recent of the usually quadrennial European internal dosimetry meetings was held in Montpellier, France. Based on questions and discussions at that meeting, Health Physics Society (HPS) Past President Ray Guilmette of Los Alamos National Laboratory (LANL) organized and cochaired with Keith Eckerman a special session onCurrent Topics in Internal Dose Assessment.” For a session scheduled on the last day of the Annual HPS Meeting in Portland, Oregon, one might not expect a huge turnout. However, the session was intense and riveting, with well over 100 people at the beginning, and perhaps 60 holding on until well after noon, after the official ending of the meeting. First, Guilmette invited six of our best and brightest in the internal dosimetry and dose reconstruction community. Then he challenged each to answer five questions on assessment or reconstruction of doses due to intakes of radionuclides: Who is the customer (for the dose assessment)? What are the rules and constraints for the dose assessment? What are the appropriate methods, models, and calculation techniques? What are the dose endpoints? How are uncertainties handled?

  4. Mechanical properties of dental Ti-Ag alloys with 22.5, 25, 27.5, and 30 mass% Ag.

    The mechanical properties -tensile strength, yield strength, elongation after fracture, Vickers hardness, and Young's modulus-and the phases of Ti-Ag alloys were investigated, as prepared with 22.5, 25, 27.5, and 30 mass% Ag. The tensile strength, yield strength, hardness, and Young's modulus of the alloys increase with their Ag content up to 25 mass%, but their breaking elongation decreases. These changes in the mechanical properties are attributed to solid-solution strengthening of the α-titanium phase, to Ti2Ag precipitation, and to the formation of eutectic structures composed of α+Ti2Ag. The addition of Ag, at 25 mass% in particular, improves the mechanical properties of these alloys, making them suitable for high strength dental prostheses, such as implantretained superstructures and narrow-diameter implants.

  5. Paleomagnetic Evidence for Spatially Distributed Post-Miocene Rotation of Western Washington and Oregon

    1984-06-01

    Anomalous paleomagnetic directions have been determined for 17 sites in the Frenchmans Springs member of the Wanapum basalt formation, Columbia River basalt group. These sites are located in the Ginkgo flows from near Vantage, Washington, to Portland, Oregon, a distance of approximately 300 km. The average paleomagnetic direction for six of these sites, centered around Vantage is D = 147°, I = 41°, α95 = 4.5°. The expected Miocene field direction is D = 355°, I = 65°. At some localities there are two distinct Ginkgo flows, in direct stratigraphic succession, with statistically identical anomalous directions. Their anomalous paleomagnetic direction makes these flows a valuable marker horizon in the Columbia River basalt group. The nondipole field direction of the Ginkgo flows correlates well with available results from the Miocene Cape Foulweather basalts of Oregon. This correlation strongly supports the hypothesis that these coastal basalts of Oregon are the distal ends of Columbia Plateau derived basalt flows. The spatial distribution of these anomalous field directions suggests about 14° of clockwise rotation between Vantage and Portland. Combining these data with data from the Oregon Coast basalts allows a maximum declination difference of about 35°. The increase in declination can be best explained by clockwise rotation, about nearby vertical axes, increasing to the southwest across the Columbia Plateau and Oregon coast.

  12. Sedimentary Basins: A Deeper Look at Seattle and Portland's Earthquake Hazards

    NASA Astrophysics Data System (ADS)

    Thompson, M.; Frankel, A. D.; Wirth, E. A.; Vidale, J. E.; Han, J.

    2015-12-01

    Seattle, Washington and Portland, Oregon, two major metropolitan areas in the Pacific Northwest, are vulnerable to earthquakes on active local faults, deep intraslab earthquakes, and megathrust earthquakes on the Cascadia Subduction Zone (CSZ). Both cities are located within sedimentary basins that could increase this hazard. The Seattle basin is ~8 km in depth and is located beneath downtown Seattle. The 6-km-deep Tualatin basin (McPhee et al., 2014) sits below and west of downtown Portland with the shallow Portland basin to the northeast. Unlike other West Coast sedimentary basins, the Tualatin contains a higher-velocity Columbia River basalt layer between sediment layers. The velocity contrast between stiff bedrock surrounding the basins and soft sediment within can cause seismic waves to amplify greatly, increasing shaking intensity and duration at the surface. For example, our observations show amplification of seismic waves by factors of 2 - 4 within the Seattle basin. Basin geometry can also increase local shaking by converting incident S-waves to surface waves, and focusing S-waves at basin edges. We characterize effects of the Seattle, Tualatin and Portland basins by modeling with 3-D numerical methods. To evaluate these effects, we use data from the 2001 M6.8 Nisqually, the 2009 M4.5 Kingston, and the 2006 M3.8 Vancouver earthquakes recorded by stations operated by the US Geological Survey (10 - 25 stations) and the Pacific Northwest Seismic Network (7 - 81 stations). Time differences between S-waves and S-converted-to-P-waves at basin/bedrock interfaces as well as reverberations from teleseisms (global earthquakes) are used to constrain the basin depth and structure of the three basins. Basin effects are modeled using a 3D finite difference program to generate synthetic seismograms. Results will be used to improve the Seattle and Portland 3D velocity models and to better understand and predict amplification of strong motion. We also plan similar analyses

    2010-01-01

    This geodatabase is an inventory of existing landslides in the Little North Santiam River Basin, Oregon (2009). Each landslide feature shown has been classified according to a number of specific characteristics identified at the time recorded in the GIS database. The classification scheme was developed by the Oregon Department of Geology and Mineral Industries (Burns and Madin, 2009). Several significant landslide characteristics recorded in the database are portrayed with symbology on this map. The specific characteristics shown for each landslide are the activity of landsliding, landslide features, deep or shallow failure, type of landslide movement, and confidence of landslide interpretation. These landslide characteristics are determined primarily on the basis of geomorphic features, or landforms, observed for each landslide. This work was completed as part of the Master's thesis "Turbidity Monitoring and LiDAR Imagery Indicate Landslides are Primary Source of Suspended-Sediment Load in the Little North Santiam River Basin, Oregon, Winter 2009-2010" by Steven Sobieszczyk, Portland State University and U.S. Geological Survey. Data layers in this geodatabase include: landslide deposit boundaries (Deposits); field-verfied location imagery (Photos); head scarp or scarp flanks (Scarp_Flanks); and secondary scarp features (Scarps).The geodatabase template was developed by the Oregon Department of Geology and Mineral Industries (Burns and Madin, 2009).

    The Washougal 7.5’ quadrangle spans the boundary between the Portland Basin and the Columbia River Gorge, approximately 30 km east of Portland, Oregon. The map area contains the westernmost portion of the Columbia River Gorge National Scenic area as well as the rapidly growing areas surrounding the Clark County, Washington, cities of Camas and Washougal. The Columbia River transects the map area, and two major tributaries, the Washougal River in Washington and the Sandy River in Oregon, also flow through the quadrangle. The Columbia, Washougal, and Sandy Rivers have all cut deep valleys through hilly uplands, exposing Oligocene volcanic bedrock in the north part of the map area and lava flows of the Miocene Columbia River Basalt Group in the western Columbia River Gorge. Elsewhere in the map area, these older rocks are buried beneath weakly consolidated to well-consolidated Neogene and younger basin-fill sedimentary rocks and Quaternary volcanic and sedimentary deposits. The Portland Basin is part of the Coastal Lowland that separates the Cascade Range from the Oregon Coast Range. The basin has been interpreted as a pull-apart basin located in the releasing stepover between two en echelon, northwest-striking, right-lateral fault zones. These fault zones are thought to reflect regional transpression, transtension, and dextral shear within the forearc in response to oblique subduction of the Pacific plate along the Cascadia Subduction Zone. The southwestern margin of the Portland Basin is a well-defined topographic break along the base of the Tualatin Mountains, an asymmetric anticlinal ridge that is bounded on its northeast flank by the Portland Hills Fault Zone, which is probably an active structure. The nature of the corresponding northeastern margin of the basin is less clear, but a series of poorly defined and partially buried dextral extensional structures has been hypothesized from topography, microseismicity, potential-field anomalies, and reconnaissance

  7. Assessing effects of PCB exposure on American mink (Mustela vison) abundance in Portland Harbor.

    PubMed

    Luxon, Matt; Toll, John; Hanson, Craig

    2014-01-01

    This article presents an integrated analysis using a Monte Carlo exposure model, dose–response effects model and habitat,and population dynamics models, all of which allow us to quantitatively estimate the effects of polychlorinated biphenyl (PCB)exposure on American mink (Mustela vison) abundance at the Portland Harbor Superfund Site (Site), and the associated uncertainties. The Site extends from river mile 1.9 of the Lower Willamette River, near its confluence with the Columbia River, to river mile 11.8, just downstream of downtown Portland, Oregon. The potential effects of PCBs on the American mink population were evaluated in the Baseline Ecological Risk Assessment (BERA) due to the historical presence of mink in the are a and because mink are known to be highly sensitive to the effects of PCBs. Hazard quotients (HQs) calculated in the BERA indicated that PCB concentrations measured in Portland Harbor fish were above levels known to cause reproductive effects in mink. Further analysis was needed to evaluate the potential magnitude of effects on the Site mink population. The integrated analysis presented herein demonstrates that if an effect of PCB exposure is a less than 30% reduction in kit production, then PCB remediation is not expected to have any effect on mink abundance. This is a Site‐specific conclusion that depends on the quality, abundance, and distribution of mink habitat in Portland Harbor. The PCB dose associated with a 30% reduction in kit production was calculated as 101 mg/kg bw/d (90% CI ¼ 69–146 mg/kg bw/d). The mink PCB dose estimates from the Portland Harbor BERA indicate that if mink are present, their baseline exposure levels probably exceed 101 mg/kg bw/d. Therefore, some level of reduction in PCB exposure could be beneficial to the species if the study area provides sufficient habitat to support a mink population. This analysis demonstrates that risk analysis for population‐level assessment endpoints benefits from analyses

    Although situated between two States (California and Washington) that have has many violent earthquakes, Oregon is noticeably less active seismically. the greatest damage experienced resulted from a major shock near Olympia, Wash., in 1949. During the short history record available (since 1841), 34 earthquakes of intensity V, Modified Mercalli Scale, or greater have centered within Oregon or near its borders. Only 13 of the earthquakes had an intensity above V, and many of the shocks were local. However, a 1936 earthquake in the eastern Oregon-Washington region caused extensive damage and was felt over an area of 272,000 square kilometers.

    2008-01-01

    The Camas 7.5' quadrangle is in southwestern Washington and northwestern Oregon approximately 20 km east of Portland. The map area, bisected by the Columbia River, lies on the eastern margin of the Portland Basin, which is part of the Puget-Willamette Lowland that separates the Cascade Range from the Oregon Coast Range. Since late Eocene time, the Cascade Range has been the locus of an episodically active volcanic arc associated with underthrusting of oceanic lithosphere beneath the North American continent along the Cascadia Subduction Zone. Bedrock consists largely of basalt and basaltic andesite flows that erupted during late Oligocene time from one or more vents located outside the map area. These rocks crop out only north of the Columbia River: at the base of Prune Hill in Camas, where they dip southward at about 5?; and east of Lacamas Creek, where they dip to the southeast at 15 to 30?. The volcanic bedrock is unconformably overlain by Neogene sediments that accumulated as the Portland Basin subsided. In the Camas quadrangle, most of these sediments consist of basaltic hyaloclastic debris generated in the volcanic arc to the east and carried into the Portland Basin by the ancestral Columbia River. The dominant structures in the map area are northwest-striking dextral strike-slip faults that offset the Paleogene basin floor as well as the lower part of the basin fill. The Oligocene rocks at Prune Hill and to the east were uplifted in late Pliocene to early Pleistocene time within a restraining bend along one of these dextral faults. In Pleistocene time, basaltic andesite flows issued from a volcano centered on the west side of Prune Hill; another flow entered the map area from the east. These flows are part of the Boring volcanic field, which comprises several dozen late Pliocene and younger monogenetic volcanoes scattered throughout the greater Portland region. In latest Pleistocene time, the Missoula floods of glacial-outburst origin inundated the Portland

  16. U.S. Geological Survey ground-water studies in Oregon

    The use of groundwater in Oregon is expected to increase owing to continued population growth and to surface water supplies that are inadequate to meet present or future demand. The major groundwater issues in Oregon are: conjunctive use of surface and groundwater; contamination from hazardous wastes, leakage from underground gasoline and diesel tanks, naturally occurring brackish water, and high concentrations of dissolved iron; groundwater availability; and Indian water rights. Before 1987, the Oregon Water Resources Department, in cooperation with the U.S. Geological Survey (USGS), maintained a network of about 400 observation wells in Oregon to monitor fluctuations in groundwater levels. Water levels currently are measured cooperatively only in active project areas. The USGS has conducted more than 120 hydrologic investigations in Oregon. During fiscal year 1987, the USGS entered into cooperative agreements with 23 local, State, and Federal agencies to conduct hydrologic investigations in Oregon; six investigations included quantitative studies of groundwater. Examples of these groundwater studies are: groundwater hydrology of the Portland basin; groundwater hydrology in the Umatilla Plateau; and iron geochemistry of a sand dune aquifer near Coos Bay.

    25,27-Bis{1'-N-(1-pyrenyl)-aminocarbonylmethyl-1H-[1',2',3']tri-azolyl-4'-methoxy}-26,28-dihydroxycalix[4]arene, 4, is synthesized as a fluorescent chemosensor for the selective detection of both anions and ion pairs in MeCN. Sensor 4 uses bis-triazoles as ligands to bind a metal ion, bis-amides and bis-triazoles as the sites to recognize anions, and pyrenes as fluorophores. Among eight anions screened, chemosensor 4 showed a marked fluorescence change toward F(-), H2PO4(-) and AcO(-), but 4 responded to each anion in a distinct way. In the presence of F(-) at low concentrations, the dynamic excimer emission of compound 4 at λ(max) 482 nm was quenched, but an emission at λ(max) 472 nm appeared at large doses of F(-). A control compound 6 showed very similar red shifts in the UV-vis and excitation spectra as 4 did, and its 472 nm emission band grew as the fluoride doses increased. Thus, the growth of the 472 nm emission of 4 and 6 in the presence of excess F(-) may be because strong H-bonding interactions of amido protons with F(-) favoured the formation of pyrene dimers in the ground state with charge transfer characteristics. The addition of H2PO4(-), unlike F(-), to a solution of 4 showed an enhanced monomer emission but a decreased excimer emission (λ(max) 482 nm). Adding AcO(-) to 4 produced a systematic change from a dynamic excimer (λ(max) 482 nm) to λ(max) 472 nm but with very little change in the UV-vis spectrum. Time-resolved fluorescence measurements on compound 6 with F(-) and AcO(-) confirmed that the 472 nm emission band mainly came from static excimers for the former, but was partly from a dynamic excimer for the latter because it contained a growth component in the fluorescence decay traces. Without pre-treatment with an anion, chemosensor 4 showed recognition of only metal ions Cu(2+), Hg(2+) and Cr(3+), but it became sensitive to Ag(+) when it was pretreated with fluoride.

  18. Conceptual communications system design in the 25.25-27.5 and 37.0-40.5 GHz frequency bands

    Future space applications are likely to rely heavily on Ka-band frequencies (20-40 GHz) for communications traffic. Many space research activities are now conducted using S-band and X-band frequencies, which are becoming congested and require a degree of pre-coordination. In addition to providing relief from frequency congestion, Ka-band technologies offer potential size, weight, and power savings when compared to lower frequency bands. The use of the 37.0-37.5 and 40.0-40.5 GHz bands for future planetary missions was recently approved at the 1992 World Administrative Radio Conference (WARC-92). WARC-92 also allocated the band 25.25-27.5 GHz to the Intersatellite Service on a primary basis to accommodate Data Relay Satellite return link requirements. Intersatellite links are defined to be between artificial satellites and thus a communication link with the surface of a planetary body, such as the moon, and a relay satellite orbiting that body are not permitted in this frequency band. This report provides information about preliminary communications system concepts for forward and return links for earth-Mars and earth-lunar links using the 37.0-37.5 (return link) and 40.0-40.5 (forward link) GHz frequency bands. In this study we concentrate primarily on a conceptual system for communications between earth and a single lunar surface terminal (LST), and between earth and a single Mars surface terminal (MST). Due to large space losses, these links have the most stringent link requirements for an overall interplanetary system. The earth ground station is assumed to be the Deep Space Network (DSN) using either 34 meter or 70 meter antennas. We also develop preliminary communications concepts for a space-to-space system operating at near 26 GHz. Space-to-space applications can encompass a variety of operating conditions, and we consider several 'typical' scenarios described in more detail later in this report. Among these scenarios are vehicle-to-vehicle communications

    Many anthropogenic disturbances have contributed to the decline of Pacific lampreys (Entosphenus tridentatus), but potential negative effects of contaminants on lampreys are unclear. Lamprey ammocoetes are the only detritivorous fish in the lower Willamette River, Oregon, USA, and have been observed in Portland Harbor sediments. Their long benthic larval stage places them at risk from the effects of contaminated sediment. The authors developed experimental methods to assess the effects of contaminated sediment on the growth and behavior of field-collected ammocoetes reared in a laboratory. Specifically, they developed methods to assess individual growth and burrowing behavior. Burrowing performance demonstrated high variability among contaminated sediments; however, ammocoetes presented with noncontaminated reference sediment initiated burrowing more rapidly and completed it faster. Ammocoete reemergence from contaminated sediments suggests avoidance of some chemical compounds. The authors conducted long-term exposure experiments on individually held ammocoetes using sediment collected from their native Siletz River, which included the following: contaminated sediments collected from 9 sites within Portland Harbor, 2 uncontaminated reference sediments collected upstream, 1 uncontaminated sediment with characteristics similar to Portland Harbor sediments, and clean sand. They determined that a 24-h depuration period was sufficient to evaluate weight changes and observed no mortality or growth effects in fish exposed to any of the contaminated sediments. However, the effect on burrowing behavior appeared to be a sensitive endpoint, with potentially significant implications for predator avoidance.

    In 25--27 May 2006 an International Conference on Actual Problems in Celestial Mechanics and Dynamical Astronomy was organized at Cluj-Napoca. The Faculty of Mathematics and Computer Science of the Babeş-Bolyai University, the host of this conference, organized this scientific meeting in collaboration with the Loránd Eötvös University (Budapest, Hungary), Sapientia University (Miercuria Ciuc, Romania), Astronomical Institute of the Romanian Academy (Bucharest, Romania) and Institute for Space Science (Bucharest, Romania). The main topics covered by the meeting were: - Solar-System dynamics, stability, resonances, chaos; - Dynamics of populations in the Solar System: NEAs, MBAs, Centaurs, KBOs, TNOs: observations, orbits, theoretical models; - Galactic and extragalactic dynamics; - Problems, models, methods and techniques in contemporary celestial mechanics and dynamical astronomy. The conference was structured into seven sessions of oral presentations, a poster session and a round table discussion. Each of the seven main sessions began with an invited lecture. These lectures reviewed the following fields: the Sitnikov problem (R. Dvorak, Austria); the age of the asteroid families (Z. Knezevic, Serbia and Montenegro); stability of exoplanetary systems (B. Érdi, Hungary); Saari's conjecture (Diacu, Canada); integrability from direct and inverse standpoints (G. Bozis, Greece); stability of exact solutions in restricted many-body problems (E. Grebenicov, Russia); actual Romanian research in post-Newtonian dynamics (V. Mioc, Romania). Beside the invited lectures, the 21 oral presentations covered the most various domains of celestial mechanics and dynamical astronomy. Chaotic behaviour was a premier topic. It was approached and studied by analytical, geometrical and numerical methods in many astronomical problems: the restricted three-body problem (with examples in the Solar System), the Gylden's model and its generalizations, capture domain, resonances, etc

    The Community Health Improvement Partnership (CHIP) model has supported community health development in more than 100 communities nationally. In 2011, four rural Oregon CHIPs collaborated with investigators from the Oregon Rural Practice-based Research Network (ORPRN), a component of the Oregon Clinical and Translational Research Institute (OCTRI), to obtain training on research methods, develop and implement pilot research studies on childhood obesity, and explore matches with academic partners. This article summarizes the experiences of the Lincoln County CHIP, established in 2003, as it transitioned from CHIP to Community Health Improvement and Research Partnership (CHIRP). Our story and lessons learned may inform rural community-based health coalitions and academicians who are engaged in or considering Community-based participatory research (CBPR) partnerships. Utilizing existing infrastructure and relationships in community and academic settings provides an ideal starting point for rural, bidirectional research partnerships. PMID:24056513

    Purpose. To investigate outcomes after coaxial 2.2 mm small incision cataract surgery combined with hybrid 25-27-gauge vitrectomy in eyes with vitreoretinal disease and age-related cataract. Methods. A single-center, retrospective case series study of 55 subjects (55 eyes) with a mean age of 70 years who underwent combined small incision phacoemulsification, intraocular lens (IOL) implantation, and hybrid 25-27-gauge vitrectomy during the 12-month period to December 2014. Intraoperative and postoperative complications and visual results were the main outcome measures. Results. The mean follow-up period was 6 months (range: 2–18 months). Intraoperative findings were 3 retinal breaks (5.5%). No cases required corneal or scleral suture or conversion to larger-gauge vitrectomy. Postoperative complications consisted of posterior capsule opacification (12.7%), elevated intraocular pressure >30 mmHg (1.8%), and fibrin reaction (5.5%). There were no cases of hypotony (<7 mmHg), IOL decentration, or postoperative endophthalmitis. Visual acuity (mean ± SD) improved from 0.52 ± 0.6 logMAR preoperatively to 0.22 ± 0.46 logMAR at final postoperative visit (P < 0.0001). Conclusion. Surgical and visual outcomes suggest hybrid 25-27-gauge vitrectomy combined with small incision phacoemulsification and IOL implantation is feasible, safe, and effective as a one-step surgical procedure for the management of vitreoretinal pathologies and concurrent cataract.

    1983-01-01

    The number of domestic wells and domestic-water use have increased rapidly since 1960 in the 250-square-mile study area southeast of Portland, Oregon. The rolling upland area is underlain by volcanic and stream-deposited rocks, all units of which serve as aquifers locally. Depths of wells range from less than 50 to more than 1,000 feet and yields from less than one to several hundred gallons per minute. Local recharge rates are judged to be adequate for any forseeable projected development for domestic water supplies. Wells are expected to yield adequate water for domestic needs nearly everywhere in the study area. However, some exploration, as by test drilling, may be needed in siting irrigation, industrial, or public-supply wells of moderate to high yield. Additional ground water can be developed from all aquifers, but the Columbia River Basalt Group is considered susceptible to problems of overdevelopment locally. (USGS)

  6. Swelling and Stress Relaxation in Portland Brownstone

    NASA Astrophysics Data System (ADS)

    Jimenez, I.; Scherer, G.

    2003-04-01

    Portland Brownstone (PB) is an arkose sandstone extensively used in the northeast-ern USA during the nineteenth century. This reddish-brown stone contains a fraction of swelling clays that are thought to contribute to its degradation upon cycles of wet-ting and drying. During drying events, contraction of the drying surface leads to stresses approaching the tensile strength of the stone. However, we have found that the magnitude of these stresses is limited by the ability of the stone to undergo stress relaxation. In this paper we describe novel methods to determine the magnitude of the stresses and the rate at which they develop and relax. We also discuss the influ-ence of surfactants on the magnitude of swelling and the rate of the stress relaxation of PB. The implications of our findings for the understanding of damage due to swelling of clays are discussed.

  7. Hydrology of the Johnson Creek Basin, Oregon

    Lee, Karl K.; Snyder, Daniel T.

    2009-01-01

    The Johnson Creek basin is an important resource in the Portland, Oregon, metropolitan area. Johnson Creek forms a wildlife and recreational corridor through densely populated areas of the cities of Milwaukie, Portland, and Gresham, and rural and agricultural areas of Multnomah and Clackamas Counties. The basin has changed as a result of agricultural and urban development, stream channelization, and construction of roads, drains, and other features characteristic of human occupation. Flooding of Johnson Creek is a concern for the public and for water management officials. The interaction of the groundwater and surface-water systems in the Johnson Creek basin also is important. The occurrence of flooding from high groundwater discharge and from a rising water table prompted this study. As the Portland metropolitan area continues to grow, human-induced effects on streams in the Johnson Creek basin will continue. This report provides information on the groundwater and surface-water systems over a range of hydrologic conditions, as well as the interaction these of systems, and will aid in management of water resources in the area. High and low flows of Crystal Springs Creek, a tributary to Johnson Creek, were explained by streamflow and groundwater levels collected for this study, and results from previous studies. High flows of Crystal Springs Creek began in summer 1996, and did not diminish until 2000. Low streamflow of Crystal Springs Creek occurred in 2005. Flow of Crystal Springs Creek related to water-level fluctuations in a nearby well, enabling prediction of streamflow based on groundwater level. Holgate Lake is an ephemeral lake in Southeast Portland that has inundated residential areas several times since the 1940s. The water-surface elevation of the lake closely tracked the elevation of the water table in a nearby well, indicating that the occurrence of the lake is an expression of the water table.

    2016-05-19

    Model simulations (scenarios) were run with lower water surface elevations in Crystal Springs Lake and increased shading to the lake to assess the relative effect the lake and pond characteristics have on water temperature. The Golf Pond was unaltered in all scenarios. The models estimated that lower lake elevations would result in cooler water downstream of the Golf Pond and shorter residence times in the lake. Increased shading to the lake would also provide substantial cooling. Most management scenarios resulted in a decrease in 7-day average of daily maximum values by about 2.0– 4.7 °F (1.1 –2.6 °C) for outflow from Crystal Springs Lake during the period of interest. Outflows from the Golf Pond showed a net temperature reduction of 0.5–2.7 °F (0.3–1.5 °C) compared to measured values in 2014 because of solar heating and downstream warming in the Golf Pond resulting from mixing with inflow from Reed Lake.

  11. Celebrating 24 years of Public Outreach of Science and Engineering in Portland Oregon

    2012-02-01

    There have been several core strategies in our highly successful 24-year Science, Technology and Society outreach program. However, the strategy for each season is also dynamic, requiring innovation and novel coalitions. As Bob Dylan put it so succinctly, ``He not busy being born is busy dying.'' Public outreach programs - as the Chautauquas of the past - should be positioned in the cultural milieu along with the opera, symphony and theatre. Support for the enterprise needs to be a broad and diverse coalition, based ideally on the creative formation of win-win relationship. You want people to see your success as their success: ``Together we can enhance the intellectual environment in ways that none of us could do alone.'' Being multi-disciplinary presents challenges but has considerable advantages. For instance, enlightened managers of established organizations recognize the value of exposing their employees to a diversity of problem solving approaches. Instead of inviting speakers for one large lecture we now invite them to be Resident Scholars for two-three days and develop a range of additional smaller public engagements. Science and engineering topics must be relevant - placed in the broader Science, Technology and Society framework. We avoid ``gee-whiz'' in favor of what stimulates reflection on who we are, where we came from, and our role in the universe. I will briefly review how we have survived and thrived and, finally, what I see as future trends and opportunities.

    Carpenter, Kurt D.; McGhee, Gordon

    2009-01-01

    Organic compounds studied in this U.S. Geological Survey (USGS) assessment generally are man-made, including pesticides, gasoline hydrocarbons, solvents, personal care and domestic-use products, disinfection by-products, and manufacturing additives. In all, 56 compounds were detected in samples collected approximately monthly during 2003-05 at the intake for the Clackamas River Water plant, one of four community water systems on the lower Clackamas River. The diversity of compounds detected suggests a variety of different sources and uses (including wastewater discharges, industrial, agricultural, domestic, and others) and different pathways to drinking-water supplies (point sources, precipitation, overland runoff, ground-water discharge, and formation during water treatment). A total of 20 organic compounds were commonly detected (in at least 20 percent of the samples) in source water and (or) finished water. Fifteen compounds were commonly detected in source water, and five of these compounds (benzene, m- and p-xylene, diuron, simazine, and chloroform) also were commonly detected in finished water. With the exception of gasoline hydrocarbons, disinfection by-products, chloromethane, and the herbicide diuron, concentrations in source and finished water were less than 0.1 microgram per liter and always less than human-health benchmarks, which are available for about 60 percent of the compounds detected. On the basis of this screening-level assessment, adverse effects to human health are assumed to be negligible (subject to limitations of available human-health benchmarks).

    2009-11-01

    This report describes the process and results of a demonstration of solid-state lighting (SSL) technology in a residential street lighting application, under the U.S. Department of Energy GATEWAY Solid-State Lighting Technology Demonstration Program. In this project, eight 100W (nominal) high-pressure sodium cobra head fixtures were replaced with a like number of LED street light luminaires manufactured by Leotek, Inc. The Leotek product achieved an estimated payback in the Lija Loop installation of about 20 years for replacement scenarios and a much shorter 7.6 years for new installations. Much of the associated energy savings (55%) supporting these payback periods, however, were achieved by reducing average horizontal photopic illuminance a similar amount (53%). Examined from a different perspective, the measured performance suggests that the Leotek product is at approximate parity with the HPS cobra head in terms of average delivered photopic illumination for a given power consumption. HPS comprises the second most efficacious street lighting technology available, exceeded only by low pressure sodium (LPS). LPS technology is not considered suitable for most street lighting applications due to its monochromatic spectral output and poor color rendering ability; therefore, this LED product is performing at an efficiency level comparable to its primary competition in this application.

    2013-10-01

    The Oregon Sustainability Center (OSC) was to represent a unique public/private partnership between the city of Portland, Oregon, state government, higher education, non-profit organizations, and the business community. A unique group of stakeholders partnered with the U.S. Department of Energy (DOE) technical expert team (TET) to collaboratively identify, analyze, and evaluate solutions to enable the OSC to become a high-performance sustainability landmark in downtown Portland. The goal was to build a new, low-energy mixed-use urban high-rise that consumes at least 50 percent less energy than requirements set by Energy Standard 90.1-2007 of the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE), the American National Standards Institute (ANSI), and the Illuminating Engineering Society of America (IESNA) as part of DOE’s Commercial Building Partnerships (CBP) program.1 In addition, the building design was to incorporate renewable energy sources that would account for the remaining energy consumption, resulting in a net zero building. The challenge for the CBP DOE technical team was to evaluate factors of risk and components of resiliency in the current net zero energy design and analyze that design to see if the same high performance could be achieved by alternative measures at lower costs. In addition, the team was to use a “lens of scalability” to assess whether or not the strategies could be applied to more projects. However, a key component of the required project funding did not pass, and therefore this innovative building design was discontinued while it was in the design development stage.

    1984-01-01

    A mineral survey of the Three Sisters Wilderness, Oregon indicated little promise for the occcurrence of metallic mineral resources. Block pumice suitable for commercial uses occurs at an undeveloped claim at Rock Mesa in the wilderness, but numerous other sources occur outside the wilderness closer to markets. A broad area centered around South Sister volcano is among the most favorable targets for geothermal resources in the Oregon Cascade Range, based on the very young age and large volume of silicic volcanic rocks that occur in this area. Deep exploration holes could be drilled in areas outside the wilderness south of South Sister to provide data on the subsurface thermal and hydrologic regimes in the southern part of the area most likely to contain geothermal resources.

    2004-09-01

    The OHP has been successful in its goal of decreasing the number of uninsured in the state of Oregon and providing them with quality medical care at an affordable rate. When the plan started, nearly one-third of those individuals falling at or below the federal poverty level had no health insurance, and the plan has provided for these individuals. Furthermore, approximately 18% of all Oregonians had no health insurance in 1990. In 1997, the uninsured population fell to about 8%3. Also, the prioritization list has established an effective basic Medicaid benefit package that could be used by other state Medicaid programs and by insurance companies. Also, the use of Managed Care Plans and setting priorities for health care services has made the cost of health care for more customers affordable. The OHP is not perfect and will always be in a constant state of flux, because of changes in the financial state of Oregon and/or changes in the health care needs of the state. Therefore, the OHP will need to be continually evaluated on periodic bases for any needed changes. However, the state of Oregon should be commended for their attempt to explore uncharted waters, and to try to find an answer to the Nation's biggest health care concern/problem, which is to provide medical coverage for everyone in an affordable manner.

    DOE has prepared an Environmental Assessment (EA) (DOE/EA-0921) evaluating the proposed construction and operation of the Ambulatory Research and Education Center (AREC), which would be located on the top seven floors of the existing NeuroSensory Research Center (NRC) on the campus of the Oregon Health Sciences University (OHSU) at Portland, Oregon. The proposed action would combine activities scattered across the campus into a central facility. Based on the analysis in the EA, DOE has determined that the proposed action does not constitute a major Federal action significantly affecting the quality of the human environment within the meaning of the National Environmental Policy Act (NEPA) of 1969, 42 USC 4321 et seq. Therefore, an environmental impact statement (EIS) is not required and the Department is issuing this Finding of No Significant Impact (FONSI).

    A carefully orchestrated fund-raising and media relations campaign contributed to the opening earlier this year of the new Oregon Burn Center on Legacy Health System's Emanuel Hospital campus, Portland, Ore. The new $5 million center is the only facility of its kind between Sacramento, Calif., Salt Lake City and Seattle. It replaces the original 12-bed facility built in 1973. The expanded center has 16 beds in 16 private rooms, treatment areas designed for children and a host of other state-of-the-art improvements that make the Oregon Burn Center among the nation's finest. Between Legacy's investment of $3 million and contributions from Oregonians, more than $5 million was raised for the new center. Beyond that, annual giving, which amounted to $85,000 in fiscal 2001, is holding steady in 2002.

    2016-02-01

    The conductometric sensor based on 25,27-di-(5-thio-octyloxy)calix[4]arene-crown-6 was developed for the quantitative analysis of ammonium. The calixarene was immobilized on the surface of the planar interdigitated electrodes by attachment of its dialkyl sulfide groups to the surface of the gold electrodes. The intrinsic ability of the calixarene to capture ammonium was studied in the conductometric measuring mode and by the electrochemical impedance spectroscopy. The developed sensor showed high selectivity to ammonium in the presence of mono-, di-, and trivalent cations. Selective and highly sensitive detection of ammonium resulted from the complexation between the ammonium ions and a crown-ether fragment of the upper rim of the 25,27-di-(5-thio-octyloxy)calix[4]arene-crown-6 macrocycle. The developed sensor had high signal repeatability. Its sensitivity was found to be satisfactory for the forthcoming sensor application in the water-sample analysis; the linear range was 0.01-1.5 mM and limit of detection 10 μM.

    In this study, 5,17-di(2-antracenylazo)-25,27-di(ethoxycarbonylmethoxy)-26,28-dihydroxycalix[4]arene has been synthesized from 2-aminoantracene and 25,27-dihydroxy-26,28-diethylacetate calix[4]arene. In order to identify the molecular structure and vibrational features of the prepared azocalix[4]arene, FT-IR and (1)H NMR spectral data have been used. FT-IR spectrum of the studied molecule is recorded in the region 4000-400 cm(-1). (1)H NMR spectrum is recorded for 0.1-0.2 M solutions in DMSO-d6 solution. The molecular geometry, infrared spectrum are calculated by the density functional method employing B3LYP level with different basis sets, including 6-31G(d) and LanL2DZ. The chemical shifts calculation for (1)H NMR of the title molecule is calculated by using by Gauge-Invariant Atomic Orbital method by utilizing the same basis sets. The total density of state, the partial density of state and the overlap population density of state diagram analysis are done via GaussSum 3.0 program. Frontier molecular orbital (HOMO-LUMO) and molecular electrostatic potential surface on the title molecule are carried out for various intramolecular interactions that are responsible for the stabilization of the molecule. The experimental results and theoretical calculations have been compared, and they are found to be in good agreement.

  6. Distribution of hypertension and renal disease in Oregon.

    Morton, W E; Knudsen, J C; Porter, G A

    1975-01-01

    Expecting to find agreement between the geographic distribution of hypertension and renal disease, we developed regional mortality rates for 1950-72 and prevalence rates for a Selective Service cohort born in 1939-41 and examined during 1957-69. For this purpose the State's counties were grouped into eight geographically homogeneous regions. The general decline in hypertension mortality was most pronounced in Portland, Oregon's major urban center. However, the decline halted during 1968-72 in the southern Cascade region which has become an area of relatively higher risk within the State. During these 23 years nephritis mortality fell, kidney infection mortality was stable, and both syndromes showed peak mortality in other, different regions of the State. The geographic pattern of hypertension prevalence among the draftee cohort resembled the 1963-67 hypertension mortality pattern, but more recent morbidity data are needed to confirm the southern Cascade region's recent change to a high-risk area. Of 529 draftees with diagnosed hypertension, only 35 percent of the cases were previously known, only 7 percent has had any previous treatment, and only 7 percent were associated with known renal conditions. Among 521 registrants with a history of renal disorders, the prevalence of hypertension was increased for all categories of renal disease but was significantly high only for those with a history of glomerulonephritis. To date in Oregon we have found no evidence that renal disorders are major determinants of hypertension morbidity or mortality. PMID:803695

  11. Odor investigation of a Portland cement plant

    SciTech Connect

    Pleus, R.C.

    1998-12-31

    The main concern expressed by Smithville residents is whether the odors they were smelling during odor events were due to chemicals that could cause adverse health effects. Odors were allegedly emanating from the town`s Portland cement plant. The purpose of the study was to measure the ambient air for 20 reduced sulfur, 50 volatile organic compounds, and air samples for olfactometric analysis. Carbonyl sulfide was found to be at a concentration that could create a sense of odor and irritation. This sense of irritation may be due to a physiological response by the central nervous system, and is not associated with any known adverse effects. This physiological response could account for some or all of the irritation experienced by residents during odor events. Comparing chemical concentrations that were detected in air samples to standard and recognized guidelines for acceptable exposure, all measured concentrations were found to be well below the acceptable criteria. From these data the authors conclude that no acute or chronic adverse health effects are expected at the concentrations of the chemicals detected downwind of the cement plant, either routinely or during odor events.

    2010-01-01

    This layer is an inventory of existing landslides deposits in the Little North Santiam River Basin, Oregon (2009). Each landslide deposit shown on this map has been classified according to a number of specific characteristics identified at the time recorded in the GIS database. The classification scheme was developed by the Oregon Department of Geology and Mineral Industries (Burns and Madin, 2009). Several significant landslide characteristics recorded in the database are portrayed with symbology on this map. The specific characteristics shown for each landslide are the activity of landsliding, landslide features, deep or shallow failure, type of landslide movement, and confidence of landslide interpretation. These landslide characteristics are determined primarily on the basis of geomorphic features, or landforms, observed for each landslide. This work was completed as part of the Master's thesis "Turbidity Monitoring and LiDAR Imagery Indicate Landslides are Primary Source of Suspended-Sediment Load in the Little North Santiam River Basin, Oregon, Winter 2009-2010" by Steven Sobieszczyk, Portland State University and U.S. Geological Survey.Data layers in this geodatabase include: landslide deposit boundaries (Deposits); field-verfied location imagery (Photos); head scarp or scarp flanks (Scarp_Flanks); and secondary scarp features (Scarps).The geodatabase template was developed by the Oregon Department of Geology and Mineral Industries (Burns and Madin, 2009).

    The Strawberry Mountain Wilderness extends 18 mi along the crest of the Strawberry Range and comprises about 53 sq mi in the Malheur National Forest, Grant County, Oregon. Systematic geologic mapping, geochemical sampling and detailed sampling of prospect workings was done. A demonstrated copper resource in small quartz veins averaging at most 0. 33 percent copper with traces of silver occurs in shear zones in gabbro. Two small areas with substantiated potential for chrome occur near the northern edge of the wilderness. There is little promise for the occurrence of additional mineral or energy resources in the Strawberry Mountain Wilderness.

    Geologic, geochemical, geophysical field and laboratory, and mine and prospect studies conducted in the Kalmiopsis Wilderness, Oregon indicate that areas within and immediately adjacent to the wilderness have substantiated mineral-resource potential. The types of mineral resources which occur in these areas include massive sulfide deposits containing copper, zinc, lead, silver and gold; podiform chromite deposits; laterite deposits containing nickel, cobalt, and chromium; lode gold deposits; and placer gold deposits. Past production from existing mines is estimated to have been at least 7000 troy oz of gold, 4000 long tons of chromite, and few tens of tons of copper ore.

    On the basis of a mineral survey, Mount Washington Wilderness, Oregon has little promise for the occurrence of metallic mineral or fossil fuel resources. Abundant cinder resources occur in the wilderness, but other large volume cinder deposits are available outside the wilderness and closer to markets. Analysis of the geothermal potential of the High Cascades province cannot be made without data on the subsurface thermal and hydrologic regimes which can only be provided by deep drill holes. Several deep holes could be drilled in areas outside the wildernesses of the High Cascades, from which extrapolations of the geothermal potential of the wildernesses could be made.

Its separation mechanism was studied and compared with octadecyl-bonded stationary phase, as well as our previously prepared para-tert-butylcalix[4]arene-1,2-crown-4 stationary phase. Meanwhile, the chromatographic behaviors were investigated by using polycyclic aromatic hydrocarbons, monosubstituted benzenes, anilines, phenols, Tanaka tests solutes, fluoroquinolones, and flavonoids as probes. Mechanisms involved in the chromatographic separation included hydrophobic, π-π and π-electron transfer, hydrogen bonding, and inclusion interactions. Moreover, the column was successfully employed for the analysis of the illegal additive of melamine in milk product.

    The production of cement involves a combination of numerous raw materials, strictly monitored system processes, and temperatures on the order of 1500 °C. Immense quantities of fuel are required for the production of cement. Traditionally, energy from fossil fuels was solely relied upon for the production of cement. The overarching project objective is to evaluate the use of alternative fuels to lessen the dependence on non-renewable resources to produce portland cement. The key objective of using alternative fuels is to continue to produce high-quality cement while decreasing the use of non-renewable fuels and minimizing the impact on the environment. Burn characteristics and thermodynamic parameters were evaluated with a laboratory burn simulator under conditions that mimic those in the preheater where the fuels are brought into a cement plant. A drop-tube furnace and visualization method were developed that show potential for evaluating time- and space-resolved temperature distributions for fuel solid particles and liquid droplets undergoing combustion in various combustion atmospheres. Downdraft gasification has been explored as a means to extract chemical energy from poultry litter while limiting the throughput of potentially deleterious components with regards to use in firing a cement kiln. Results have shown that the clinkering is temperature independent, at least within the controllable temperature range. Limestone also had only a slight effect on the fusion when used to coat the pellets. However, limestone addition did display some promise in regards to chlorine capture, as ash analyses showed chlorine concentrations of more than four times greater in the limestone infused ash as compared to raw poultry litter. A reliable and convenient sampling procedure was developed to estimate the combustion quality of broiler litter that is the best compromise between convenience and reliability by means of statistical analysis. Multi-day trial burns were conducted

    To investigate the physical properties of a novel accelerated Portland cement. The setting time, compressive strength, pH and solubility of white Portland cement (Lafarge Asland; CEM 1, 52.5 N) and accelerated Portland cement (Proto A) produced by excluding gypsum from the manufacturing process (Aalborg White) and a modified version with 4 : 1 addition of bismuth oxide (Proto B) were evaluated. Proto A set in 8 min. The compressive strength of Proto A was comparable with that of Portland cement at all testing periods (P > 0.05). Additions of bismuth oxide extended the setting time and reduced the compressive strength (P < 0.05). Both cements and storage solution were alkaline. All cements tested increased by >12% of their original weight after immersion in water for 1 day with no further absorption after 28 days. Addition of bismuth oxide increased the water uptake of the novel cement (P < 0.05). The setting time of Portland cement can be reduced by excluding the gypsum during the last stage of the manufacturing process without affecting its other properties. Addition of bismuth oxide affected the properties of the novel cement. Further investigation on the effect that bismuth oxide has on the properties of mineral trioxide aggregate is thus warranted.

    Court Decision: 368 Federal Reporter, 3d Series 1118; 2004 May 26 (date of decision). The U.S. Court of Appeals for the Ninth Circuit agreed with a lower court that a United States Attorney General's directive stating that physician assisted suicide violates the Controlled Substances Act of 1970 (CSA) and criminalizing conduct authorized by Oregon's Death with Dignity Act was unlawful and unenforceable. The State of Oregon brought a suit challenging a directive issued by United States Attorney General John Ashcroft known as the Ashcroft Directive. The Ninth Circuit held that the Directive violated the language of the CSA, breached Congress' express legislative intent, and exceeded the limits of the Attorney General's statutory authority. The court first found that the regulation of professional medical conduct is traditionally a state power and that the Attorney General may not exercise control over this power because he was not unmistakably and clearly authorized to do so by Congress. The court then held that the Directive violated the plain language of the CSA by exceeding the scope of Federal Authority articulated by the CSA, misconstruing the Attorney General's role under the statute and failing to adhere to instructions in the statute for revoking physician prescription privileges. Finally, the court held that the Attorney General exceeded the scope of his authority because Congress "empowered 'the principal health agency of the the federal government, not the Attorney General, to make medical decisions under the Act."

    On May 25-26, May 30-June 2, and June 12-13, 1980, strong, high-altitude winds from the north occurred during periods of volcanic-ash eruption at Mount St. Helens in southwestern Washington. As a result, ash fell in the Bull Run watershed, Oregon, some 50 miles to the south, the principal water-supply source for the Portland area. Samples from precipitation collectors and from stream sites in the Bull Run watershed were collected on several dates during May and June 1980. Analyses were made and are tabulated for pH, conductivity, acidity, sulfate, and nitrate plus nitrite. Field pH values of the precipitation ranged from 4.0 to 5.6 pH units and the stream samples from 6.7 to 7.5 units. Particle-size analyses for ash samples collected in the Bull Run watershed and Portland, Oregon, are also shown. Volcanic events, precipitation and high-altitude speeds for northerly winds are given for May 18-June 15, 1980. 6 references, 5 figures, 3 tables.

    The Tualatin Mountains form a northwest-striking ridge about 350 m high that separates Portland, Oregon, from the cities of the Tualatin Valley to the west. Known informally as the Portland Hills, the ridge is a late Cenozoic anticline, bounded by reverse faults that dip toward the anticlinal axis. The anticline is a broad, open fold consisting chiefly of Miocene Columbia River Basalt Group, with remnants of Miocene-Pliocene Troutdale Formation and Pleistocene basalt of the Boring Volcanic Field on the flanks of the anticline. Anticlinal structures similar to the Tualatin Mountains are characteristic of the northern Willamette Valley, where the structures accommodate margin-parallel shortening of the Cascadia fore arc. Global Positioning System (GPS) results indicate that the shortening is due to the northward motion of Oregon at several millimeters per year with respect to stable North America. Some of the uplifts may contain active faults, but the structures are poorly exposed and are overlain by thick Pleistocene loess and Missoula flood deposits. Between 1993 and 1998, construction of the 3-mile-long (4500-m-long) TriMet MAX Light Rail tunnel through the Tualatin Mountains provided an unusual opportunity to investigate the geological structure and history of the Tualatin Mountains. This report is a collaborative effort among the tunnel geologists and the U.S. Geological Survey (USGS) to document the geologic story and quantify late Cenozoic and Quaternary deformation rates of the Tualatin Mountains.

    The Saint Helens 7.5' quadrangle is situated in the Puget-Willamette Lowland approximately 35 km north Portland, Oregon. The lowland, which extends from Puget Sound into west-central Oregon, is a complex structural and topographic trough that lies between the Coast Range and the Cascade Range. Since late Eocene time, Cascade Range has been the locus of a discontinuously active volcanic arc associated with underthrusting of oceanic lithosphere beneath the North American continent along the Cascadia Subduction Zone. The Coast Range occupies the forearc position within the Cascadia arc-trench system and consists of a complex assemblage of Eocene to Miocene volcanic and marine sedimentary rocks. The Saint Helens quadrangle lies in the northern part of the Portland Basin, a roughly 2000-km2 topographic and structural depression. It is the northernmost of several sediment-filled structural basins that collectively constitute the Willamette Valley segment of the Puget-Willamette Lowland (Beeson and others, 1989; Swanson and others, 1993; Yeats and others, 1996). The rhomboidal basin is approximately 70 km long and 30 km wide, with its long dimension oriented northwest. The Columbia River flows west and north through the Portland Basin at an elevation near sea level and exits through a confined bedrock valley less than 2.5 km wide about 16 km north of Saint Helens. The flanks of the basin consist of Eocene through Miocene volcanic and sedimentary rocks that rise to elevations exceeding 2000 ft (610 m). Seismic-reflection profiles (L.M. Liberty, written commun., 2003) and lithologic logs of water wells (Swanson and others, 1993; Mabey and Madin, 1995) indicate that as much as 550 m of late Miocene and younger sediments have accumulated in the deepest part of the basin near Vancouver. Most of this basin-fill material was carried in from the east by the Columbia River but contributions from streams draining the adjacent highlands are locally important. The Portland Basin has

    Portland cement has been analyzed and compared to mineral trioxide aggregate (MTA) because of their chemical similarity. The possibility of using this material as a less expensive alternative to MTA in dental practice should be considered. In view of this, the present study compared the components of a Portland cement (Votoran) to two commercial brands of MTA (Pro-Root and MTA-Angelus). Twelve specimens of each material were fabricated and examined by scanning electron microscopy (SEM) with energy dispersive spectroscopy (EDS) to obtain their percentage of chemical elements. The means of the chemical elements found in each material was compared by descriptive statistics. Bismuth was present only in MTA cements to provide radiopacity. In conclusion, the tested cements have similar components, which supports, as far as composition is concerned, the possible clinical use of Portland as an option to MTA.

    In this study, calcined kaolin-white Portland cement geopolymer was investigated for use as biomaterial. Sodium hydroxide and sodium silicate were used as activators. In vitro test was performed with simulated body fluid (SBF) for bioactivity characterization. The formation of hydroxyapatite bio-layer on the 28-day soaked samples surface was tested using SEM, EDS and XRD analyses. The results showed that the morphology of hydroxyapatite was affected by the source material composition, alkali concentration and curing temperature. The calcined kaolin-white Portland cement geopolymer with relatively high compressive strength could be fabricated for use as biomaterial. The mix with 50% white Portland cement and 50% calcined kaolin had 28-day compressive strength of 59.0MPa and the hydroxyapatite bio-layer on the 28-day soaked sample surface was clearly evident.

    This guidebook describes stops of interest for a geological field trip around Mount Hood volcano. It was developed for the 2017 International Association of Volcanology and Chemistry of the Earth’s Interior (IAVCEI) Scientific Assembly in Portland, Oregon. The intent of this guidebook and accompanying contributions is to provide an overview of Mount Hood, including its chief geologic processes, magmatic system, eruptive history, local tectonics, and hazards, by visiting a variety of readily accessible localities. We also describe coeval, largely monogenetic, volcanoes in the region. Accompanying the field-trip guidebook are separately authored contributions that discuss in detail the Mount Hood magmatic system and its products and behavior (Kent and Koleszar, this volume); Mount Hood earthquakes and their relation to regional tectonics and the volcanic system (Thelen and Moran, this volume); and young surface faults cutting the broader Mount Hood area whose extent has come to light after acquisition of regional light detection and ranging coverage (Madin and others, this volume).The trip makes an approximately 175-mile (280-kilometer) clockwise loop around Mount Hood, starting and ending in Portland. The route heads east on Interstate 84 through the Columbia River Gorge National Scenic Area. The guidebook points out only a few conspicuous features of note in the gorge, but many other guides to the gorge are available. The route continues south on the Mount Hood National Scenic Byway on Oregon Route 35 following Hood River, and returns to Portland on U.S. Highway 26 following Sandy River. The route traverses rocks as old as the early Miocene Eagle Creek Formation and overlying Columbia River Basalt Group of middle Miocene age, but chiefly lava flows and clastic products of arc volcanism of late Miocene to Holocene age.

    1997-10-01

    Limited historical references indicate that bull trout Salvelinus confluentus in Oregon were once widely spread throughout at least 12 basins in the Klamath River and Columbia River systems. No bull trout have been observed in Oregon's coastal systems. A total of 69 bull trout populations in 12 basins are currently identified in Oregon. A comparison of the 1991 bull trout status (Ratliff and Howell 1992) to the revised 1996 status found that 7 populations were newly discovered and 1 population showed a positive or upgraded status while 22 populations showed a negative or downgraded status. The general downgrading of 32% of Oregon's bull trout populations appears largely due to increased survey efforts and increased survey accuracy rather than reduced numbers or distribution. However, three populations in the upper Klamath Basin, two in the Walla Walla Basin, and one in the Willamette Basin showed decreases in estimated population abundance or distribution.

    Walker, George W.; Neumann, Terry R.

    1984-01-01

    The Olallie Roadless Area, Oregon, is devoid of mines and mineral prospects, and a mineral-resource evaluation of the area did not identify any mineral-resource potential. There is no evidence that fossil fuels are present in the roadless area. Nearby areas in Clackamas, Marion, Jefferson, and Wasco Counties are characterized by higher-than-normal heat flow and by numerous thermal springs, some of which have been partly developed. this may indicate that the region has some, as yet undefined, potential for the development of geothermal energy. Lack of thermal springs or other evidence of localized geothermal anomalies within the roadless area may be the result of masking by young, nonconductive rock units and by the flooding out and dilution of rising thermal waters by cool meteoric water.

    The radiolytic stability of 25,27-bis(2-propyloxy)calix[4] arene -26,28-crown-6 (iPr-C[4]C-6) was studied. {sup 60}co was used as a radiation source. Its dose rate was 437 Gy/min., and the total absorbed dose of the iPr-C[4]C-6 was from 10{sup 4} to 10{sup 6} Gy. The iPr-C[4]C-6 solid and 0.025 mol/L iPr-C[4]C-6/n-octanol which were pre-equilibrated with 0.01 mol/L and 3 mol/L nitric acid, respectively, were given different doses, and their extraction performance was researched. Their degradation mechanism was investigated by mass spectrometry (MS) and infrared spectroscopy (IR). The results show that radiolytic stability of the iPr-C[4]C-6 solid and 0.025 mol/L iPr-C[4]C-6/n-octanol are good when their absorbed dose is less than 10{sup 6} Gy. The extracting system of iPr-C[4]C-6/n-octanol is promising for separating cesium from high-level liquid waste(HLLW)

  17. Cascade Mtns. Oregon

    NASA Image and Video Library

    2002-04-19

    The ground near one of the long-dormant Three Sisters volcanoes in the Cascade Mountains of west-central Oregon has risen approximately 10centimeters in a 10-by-20-km parcel since 1996, meaning that magma or underground lava is slowly flowing into the area, according to a research team from the U.S. Geological Survey. The Three Sisters area -- which contains five volcanoes -- is only about 170 miles from Mount St. Helens, which erupted in 1980. Both are part of the Cascades Range, a line of 27volcanoes stretching from British Columbia in Canada to northern California. This perspective view was created by draping a simulated natural color ASTER image over digital topography from the U.S. Geological Survey National Elevation Dataset. This image was acquired on May 28, 2000 by the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) on NASA's Terra satellite. With its 14 spectral bands from the visible to the thermal infrared wavelength region, and its high spatial resolution of 15 to 90 meters (about 50 to 300 feet), ASTER will image Earth for the next 6 years to map and monitor the changing surface of our planet. http://photojournal.jpl.nasa.gov/catalog/PIA03492

    Evaluation of occupational and general public exposure to Bacillus thuringiensis (Bt) during application of this microbial agent for control of the gypsy moth was requested by the Oregon State Department of Human Resources, Health Division, located in Portland. Bt was applied by helicopter on about 250,000 acres of forest, rural, and urban areas in 1985 and 1986. Project operational plans, accident prevention, safety plans, personal protective-equipment usage, and work practices were reviewed and evaluated. Personal exposure and area air monitoring for Bt was carried out during application. Air sampling indicated there was a widespread exposure potential. The author recommends that care be taken by those employees handling Bt in solution and that splashing of Bt to the eye be avoided due to possible corneal ulcer development. The dispersing-agent Plyac is recommended for use in handling the waste-disposal problem. Access to the mixing and application areas should be restricted.

  9. Appraisal of storm-water quality near Salem, Oregon

    USGS Publications Warehouse

    Miller, T.L.

    1987-01-01

    Stormwater runoff for the period December 1979 to May 1981, at 13 sites (12 basins) in the vicinity of Salem, Oregon, was sampled and analyzed for water quality. Constituent concentrations for urban storm water were relatively small when compared to samples from Portland and Medford, Oregon and to samples from Denver, Colorado. The data indicated that levels of suspended sediment, ultimate CBOD (carbonaceous biochemical oxygen demand), and total lead increased with increased urbanization. Much of the suspended sediment and related turbidity result from transport of basin soils rather than from the wash-off of dry fallout solids from impervious areas. Because of small chemical concentrations and winter high flow and low temperature conditions in the Willamette River, Salem storm water probably has little effect on biological or on most chemical conditions in the Willamette River. An analysis of data from a stormwater detention pond (originally designed to reduce peak flows) indicated that the facility was about 47% efficient in reducing suspended sediment loads. The facility also reduced such sediment-related constituent loads as total lead and total phosphorus. Total Kjeldahl nitrogen and ultimate CBOD loads that are transported mostly in the dissolved phase were not measurably affected by the detention pond. Precipitation samples collected at one site for a year were found to be acidic, with a median pH of 4.6. Median total lead concentration was 8 micrograms/L (ug/L) in precipitation, whereas the median total lead concentration in runoff from the 12 basins ranged from 8 to 110 ug/L. The median dissolved ammonia concentration in precipitation was larger than the median dissolved ammonia concentration at all 13 sites. In contrast, the median total Kjeldahl nitrogen concentration in precipitation samples was about half the median for streamwater concentrations. Median ratios of sulfate to chloride and nitrate to chloride in precipitation were much higher than ratios

  10. Oregon's experience: evaluating the record.

    PubMed

    Lindsay, Ronald A

    2009-03-01

    Prior to passage of the Oregon Death with Dignity Act, opponents of assistance in dying argued that legalization would have serious harmful consequences. Specifically, they argued that the quality and availability of palliative care would decline, that the harms of legalization would affect certain vulnerable groups disproportionately, that legal assisted dying could not be confined to the competent terminally ill who voluntarily request assistance, and that the practice would result in frequent abuses. Data from Oregon's decade-long experience decisively refute the first three predictions. As to abuses, the record is not quite as clear, but if an appropriate framework for analysis is utilized, the most reasonable conclusion is that the risks of abuse do not outweigh the benefits of legalization. To the extent projected harmful consequences are relevant to the debate over legalization, Oregon's experience argues in favor of legalization of assistance in dying.

  11. The Oregon Geothermal Planning Conference

    SciTech Connect

    1980-10-02

    Oregon's geothermal resources represent a large portion of the nation's total geothermal potential. The State's resources are substantial in size, widespread in location, and presently in various stages of discovery and utilization. The exploration for, and development of, geothermal is presently dependent upon a mixture of engineering, economic, environmental, and legal factors. In response to the State's significant geothermal energy potential, and the emerging impediments and incentives for its development, the State of Oregon has begun a planning program intended to accelerate the environmentally prudent utilization of geothermal, while conserving the resource's long-term productivity. The program, which is based upon preliminary work performed by the Oregon Institute of Technology's Geo-Heat Center, will be managed by the Oregon Department of Energy, with the assistance of the Departments of Economic Development, Geology and Mineral Industries, and Water Resources. Funding support for the program is being provided by the US Department of Energy. The first six-month phase of the program, beginning in July 1980, will include the following five primary tasks: (1) coordination of state and local agency projects and information, in order to keep geothermal personnel abreast of the rapidly expanding resource literature, resource discoveries, technological advances, and each agency's projects. (2) Analysis of resource commercialization impediments and recommendations of incentives for accelerating resource utilization. (3) Compilation and dissemination of Oregon geothermal information, in order to create public and potential user awareness, and to publicize technical assistance programs and financial incentives. (4) Resource planning assistance for local governments in order to create local expertise and action; including a statewide workshop for local officials, and the formulation of two specific community resource development plans.

  12. Urban heat island effects human heat-stress values in Portland (OR) during the July 2006 heat wave

    NASA Astrophysics Data System (ADS)

    Bornstein, R. D.; Melford, A.

    2009-12-01

    The Heat Index (HI), a measure of the effective temperature felt by the human body, is based on both 2-m air temperature and relative humidity (RH) values. This NWS index, however, is generally calculated by use of only airport data. It thus cannot account for urban heat island (UHI) effects, which would raise the temperature values used in its calculation, create greater HI values, and thus more accurate estimates of the danger to human populations. The current study thus uses 12 mesoscale sites around Portland, Oregon to map the UHI and resulting HI fields during the heat wave of 20-24 July 2006. Past studies have observed UHIs in the area, but temperatures during this heat wave were unusually high due to a combination of synoptic influences, i.e., high temperatures aloft, nocturnal cloud cover, and a surface high pressure area. The associated surface southerly flow of moist air also produced high RH values during both daytime (which raised HI values) and nighttime (which kept min temperatures high). Results showed two separate Portland midday UHI centers (of up to 16 F), divided by the Willamette River that flows through the city. The UHI produced significant differences in the HI values across the city, with the highest variability during the 22nd of July. HI values from the airport NWS site were much lower (up to 20 F) than those from the center of the UHI. An urbanized HI needs to thus be considered (either from mesoscale observations, statistical extrapolation, or mesoscale modeling) when forecasting HI values in urban areas.

    The U.S. District Court for the District of Oregon found unconstitutional the Oregon Death with Dignity Act, which allows a terminally ill patient to obtain a doctor's prescription for a fatal drug dosage in order to commit suicide. The court held that the state law, which classified competent terminally ill patients as a group and established procedures for them to opt for assisted suicide, was not rationally related to any legitimate state interest for purposes of the equal protection clause of the Fourteenth Ammendment. The law did not ensure rational and voluntary decision making by the terminally ill.

  14. Piloting Utility Modeling Applications (PUMA): Planning for Climate Change at the Portland Water Bureau

    NASA Astrophysics Data System (ADS)

    Heyn, K.; Campbell, E.

    2016-12-01

    The Portland Water Bureau has been studying the anticipated effects of climate change on its primary surface water source, the Bull Run Watershed, since the early 2000's. Early efforts by the bureau were almost exclusively reliant on outside expertise from climate modelers and researchers, particularly those at the Climate Impacts Group (CIG) at the University of Washington. Early work products from CIG formed the basis of the bureau's understanding of the most likely and consequential impacts to the watershed from continued GHG-caused warming. However, by mid-decade, as key supply and demand conditions for the bureau changed, it found it lacked the technical capacity and tools to conduct more refined and updated research to build on the outside analysis it had obtained. Beginning in 2010 through its participation in the Pilot Utility Modeling Applications (PUMA) project, the bureau identified and began working to address the holes in its technical and institutional capacity by embarking on a process to assess and select a hydrologic model while obtaining downscaled climate change data to utilize within it. Parallel to the development of these technical elements, the bureau made investments in qualified staff to lead the model selection, development and utilization, while working to establish productive, collegial and collaborative relationships with key climate research staff at the Oregon Climate Change Research Institute (OCCRI), the University of Washington and the University of Idaho. This presentation describes the learning process of a major metropolitan area drinking water utility as its approach to addressing the complex problem of climate change evolves, matures, and begins to influence broader aspects of the organization's planning efforts.

    In this paper we combine SO2/ash plume dispersion modelling, satellite and surface remote sensing observations to study the regional influence of a relatively weak volcanic eruption from Mount Etna on the optical and micro-physical properties of Mediterranean aerosols. We analyse the Mount Etna eruption episode of 25-27 October 2013. The evolution of the plume along the trajectory is investigated by means of the FLEXPART (FLEXible PARTicle dispersion model) Lagrangian dispersion model. The satellite dataset includes true colour images, retrieved values of volcanic SO2 and ash, and estimates of SO2 and ash emission rates derived from MODIS (MODerate resolution Imaging Spectroradiometer) observations, and estimates of cloud top pressure from SEVIRI (Spinning Enhanced Visible and InfraRed Imager). Surface remote sensing measurements of aerosol and SO2 made at the ENEA Station for Climate Observations (35.52° N, 12.63° E, 50 m a.s.l.) on the island of Lampedusa are used in the analysis. The combination of these different datasets suggests that SO2 and ash, despite the initial injection occurred at about 7.0 km altitude, reached altitudes around 10-12 km and influenced the aerosol size distribution at a distance more than 350 km downwind. This study indicates that even a relatively weak volcanic eruption may produce an observable effect on the aerosol properties at the regional scale. The impact of secondary sulphate particles on the aerosol size distribution at Lampedusa is discussed, and estimates of the clear sky direct aerosol radiative forcing are derived. Daily shortwave radiative forcing efficiencies are calculated with the LibRadtran model. They are estimated between -39 and -48 W m-2 AOD-1 at the top of the atmosphere, and between -66 and -49 W m-2 AOD-1, at the surface, with the variability in the estimates mainly depending on the aerosol single scattering albedo. These results suggest that sulphate particles played a large role, while the contribution by

    Despite advances in our understanding of the molecular and genetic basis of pancreatic cancer, the outcome for this disease remains dismal. Gemcitabine, the standard chemotherapy for pancreatic cancer, offers modest improvement of tumor-related symptoms and marginal advantage of survival. Many chemotherapeutic and targeted agents have been pitted against or combined with gemcitabine in randomized phase III trials and no drug was shown to be superior to single-agent gemcitabine except two gemcitabine-containing combinations: capecitabine plus gemcitabine vs. gemcitabine and erlotinib. In this article, the author debates: "Is there a standard of care for the treatment of advanced pancreatic cancer?". In addition, he summarizes the key studies presented at the "Gastrointestinal Cancers Symposium" held in Orlando, FL, USA on January 25-27, 2008. The studies discussed here include the following: i) a phase I study of a chemotherapy doublet gemcitabine plus capecitabine, combined with a biologic doublet (bevacizumab plus erlotinib) in patients with advanced pancreatic adenocarcinoma (abstract #141); ii) a phase II study of gemcitabine, bevacizumab, and erlotinib in locally advanced and metastatic adenocarcinoma of the pancreas (abstract #151); iii) final results of the multicenter phase II study on gemcitabine, capecitabine, and bevacizumab in patients with advanced pancreatic cancer (abstract #198); iv) interim results from a phase II study of volociximab in combination with gemcitabine in patients with metastatic pancreatic cancer (abstract #142); v) a pilot study of combination chemotherapy with S-1 and irinotecan for advanced pancreatic cancer (abstract #155); vi) a multicenter phase II study of gemcitabine and S-1 combination chemotherapy in patients with unresectable pancreatic cancer (abstract #212); vii) a phase I/II study of PHY906 plus capecitabine in patients with advanced pancreatic carcinoma (abstract #260); and viii) the final results of a phase II trial of

    Mineral trioxide aggregate (MTA) and Portland cement have been shown to be bioactive because of their ability to produce biologically compatible carbonated apatite. This study analyzed the interaction of MTA and white Portland cement with dentin in vivo. Seventy-two human dentin tubes were filled with MTA Branco, MTA BIO, and white Portland cement + 20% bismuth oxide (PC1) or PC1 + 10% of calcium chloride (PC2) and implanted subcutaneously in 18 rats at 4 sites from the dorsal area. Empty dentin tubes, implanted in rats of a pilot study, were used as control. After 30, 60, and 90 days, the animals were killed, and the dentin tubes were retrieved for scanning electron microscope analysis. In the periods of 30 and 60 days, the mineral deposition in the material-dentin interface (interfacial layer) and in the interior of dentinal tubules was detected in more tubes filled with MTA Branco and MTA BIO than in tubes filled with PC1 and PC2. After 90 days, the interfacial layer and intratubular mineralization were detected in all tubes except for 3 and 1 of the tubes filled with PC2, respectively. It was concluded that all the cements tested were bioactive. The cements released some of their components in the tissue capable of stimulating mineral deposition in the cement-dentin interface and in the interior of the dentinal tubules. MTA BIO and MTA Branco were more effective in promoting the biomineralization process than Portland cements, mainly after 30 and 60 days. Copyright © 2012 American Association of Endodontists.

  4. Reservoir-system model for the Willamette River basin, Oregon

    Shearman, James O.

    1976-01-01

    For nearly half a century the Willamette River in Oregon experienced severe dissolved-oxygen problems related to large loads of organically rich waste waters from industries and municipalities. Since the mid-1950 's dissolved oxygen quality has gradually improved owing to low-flow augmentation, the achievement of basinwide secondary treatment, and the use of other waste-management practices. As a result, summer dissolved-oxygen levels have increased, salmon runs have returned, and the overall effort is widely regarded as a singular water-quality success. To document the improved dissolved-oxygen regimen, the U.S. Geological Survey conducted intensive studies of the Willamette during the summer low-flow seasons of 1973 and 1974. During each summer the mean daily dissolved-oxygen levels were found to be higher than 5 milligrams per liter throughout the river. Because of the basinwide secondary treatment, carbonaceous deoxygenation rates were low. In addition, almost half of the biochemical oxygen demand entering the Willamette was from diffuse (nonpoint) sources rather than outfalls. These results indicated that point-source biochemical oxygen demand was no longer the primary cause of dissolved-oxygen depletion. Instead, the major causes of deoxygenation were nitrification in a shallow ' surface active ' reach below Salem and an anomalous oxygen demand (believed to be primarily of benthal origin) in Portland Harbor.

  5. Bed Mobility on the Deschutes River, Oregon: Tracer Gravel Results

    Kondolf, G. M.; Williams, J.

    2003-12-01

    The Deschutes River, drainage area 20,250 km2 near Madras, Oregon, is a gravel-bedded river, impounded since 1957 by three dams in the Pelton-Round Butte hydroelectric project, operated by Portland General Electric (PGE). Salmon spawning has declined in the reach below the dams since their construction, so possible project effects on spawning habitat are an issue of concern in relicensing of the project. Consultants to PGE applied the Parker bedload transport function to several sites below the hydroelectric dams; they concluded that the entrainment threshold flow was 340 m3s-1, and that the bed had been mobile only 25 days in the 72-year period of record from 1925-1996. However, their model was not calibrated with any actual field data of bed mobility or bedload transport, and the calculations were for full bed mobility, ignoring potentially significant bedload transport that might occur at a condition of partial mobility. To redress that lack of field data, we placed tracer gravels in the bed at three sites below the dams. In 2002 tracer gravels moved at one of the three sites after a flow of 150 m3s-1 (128-mm stones moved up to 1 m). The minor movement suggests that the bed is just beginning to move at 150 m3s-1, but indicates that the previously assumed entrainment threshold of 340 m3s-1 is too high.

    2002-01-01

    The ground near one of the long-dormant Three Sisters volcanoes in the Cascade Mountains of west-central Oregon has risen approximately 10centimeters in a 10-by-20-km parcel since 1996, meaning that magma or underground lava is slowly flowing into the area, according to a research team from the U.S. Geological Survey. The Three Sisters area -- which contains five volcanoes -- is only about 170 miles from Mount St. Helens, which erupted in 1980. Both are part of the Cascades Range, a line of 27volcanoes stretching from British Columbia in Canada to northern California. This perspective view was created by draping a simulated natural color ASTER image over digital topography from the U.S. Geological Survey National Elevation Dataset.

    This image was acquired on May 28, 2000 by the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) on NASA's Terra satellite. With its 14 spectral bands from the visible to the thermal infrared wavelength region, and its high spatial resolution of 15 to 90 meters (about 50 to 300 feet), ASTER will image Earth for the next 6 years to map and monitor the changing surface of our planet.

    ASTER is one of five Earth-observing instruments launched December 18,1999, on NASA's Terra satellite. The instrument was built by Japan's Ministry of Economy, Trade and Industry. A joint U.S./Japan science team is responsible for validation and calibration of the instrument and the data products. Dr. Anne Kahle at NASA's Jet Propulsion Laboratory, Pasadena, California, is the U.S. Science team leader; Bjorn Eng of JPL is the project manager. ASTER is the only high resolution imaging sensor on Terra. The Terra mission is part of NASA's Earth Science Enterprise, along-term research and technology program designed to examine Earth's land, oceans, atmosphere, ice and life as a total integrated system.

    The broad spectral coverage and high spectral resolution of ASTER will provide scientists in numerous disciplines with critical

    9.1 Compliance Summary The Lakeview, Oregon, Uranium Mill Tailings Radiation Control Act (UMTRCA) Title I Disposal Site was inspected September 16 and 17, 2015. Other than some ongoing concern with erosion-control rock riprap degradation, the disposal cell was in good condition. Some minor fence repairs and vegetation removal, and minor erosion repair work along the west site fence is planned. Inspectors identified no other maintenance needs or cause for a follow-up or contingency inspection. Disposal cell riprap is evaluated annually to ensure continued long-term protection of the cell from erosion during a severe precipitation event. Degradation of the rock riprap was first observed at the site in the mid-1990s. Rock gradation monitoring of the riprap on the west side slope has been performed as part of the annual inspection since 1997 to determine the mean diameter (D50) value. As prescribed by the monitoring procedure, the rock monitoring is routinely conducted at random locations. However, at the U.S. Nuclear Regulatory Commission’s (NRC’s) request, the 2015 rock monitoring approach deviated from the normal procedure by using a pre-established monitoring grid in a subset area of the west side slope. This changed the monitoring approach from random sampling to biased sampling. The D50 value measured during the 2015 gradation monitoring is 2.39 inches, which falls below the original D50 design size range of 2.7–3.9 inches for the Type B size side slope riprap. At NRC’s request, rock durability monitoring was added to the gradation monitoring in 2009 to monitor durability by rock type. Results of the 2015 durability monitoring showed that74 percent of the total rock sampled is durability class code A rock with an assigned durability class of “highly durable” or durability class code B “durable” rock, and that over 90 percent of the 3-inch or larger rock is durability class code A or B.

    Fish passage conditions through two spillways at Detroit Dam on the North Santiam River in Oregon were evaluated by Pacific Northwest National Laboratory for the U.S. Army Corps of Engineers (USACE), Portland District, using Sensor Fish devices. The objective of the study was to describe and compare passage exposure conditions through Spillbay 3 and Spillbay 6 at 1.5- and 3.5-ft gate openings, identifying potential fish injury regions of the routes. The study was performed in July 2009, concurrent with HI-Z balloon-tag studies by Normandeau Associates, Inc. Sensor Fish and live fish were deployed at elevations approximately 3 ft above structure at depths determined using a computational fluid dynamics model. Data collected were analyzed to estimate 1) exposure conditions, particularly exposure to severe collision and shear events by passage route sub-regions; 2) differences in passage conditions between passage routes; and 3) relationships to live-fish injury and mortality data estimates.

Portland cement has been used in this role since early in the commercial nuclear program as a simple and inexpensive solidification medium for immobilization of radioactive wastes. Through the use of additives, most waste streams can be satisfactorily immobilized with portland cement. However, some problem waste streams can not be solidified with portland cement at this time, and those are discussed in this document.

  13. Tectonic evolution of the Tualatin basin, northwest Oregon, as revealed by inversion of gravity data

    USGS Publications Warehouse

    McPhee, Darcy K.; Langenheim, Victoria E.; Wells, Ray; Blakely, Richard J.

    2014-01-01

    The Tualatin basin, west of Portland (Oregon, USA), coincides with a 110 mGal gravity low along the Puget-Willamette lowland. New gravity measurements (n = 3000) reveal a three-dimensional (3-D) subsurface geometry suggesting early development as a fault-bounded pull-apart basin. A strong northwest-trending gravity gradient coincides with the Gales Creek fault, which forms the southwestern boundary of the Tualatin basin. Faults along the northeastern margin in the Portland Hills and the northeast-trending Sherwood fault along the southeastern basin margin are also associated with gravity gradients, but of smaller magnitude. The gravity low reflects the large density contrast between basin fill and the mafic crust of the Siletz terrane composing basement. Inversions of gravity data indicate that the Tualatin basin is ∼6 km deep, therefore 6 times deeper than the 1 km maximum depth of the Miocene Columba River Basalt Group (CRBG) in the basin, implying that the basin contains several kilometers of low-density pre-CRBG sediments and so formed primarily before the 15 Ma emplacement of the CRBG. The shape of the basin and the location of parallel, linear basin-bounding faults along the southwest and northeast margins suggest that the Tualatin basin originated as a pull-apart rhombochasm. Pre-CRBG extension in the Tualatin basin is consistent with an episode of late Eocene extension documented elsewhere in the Coast Ranges. The present fold and thrust geometry of the Tualatin basin, the result of Neogene compression, is superimposed on the ancestral pull-apart basin. The present 3-D basin geometry may imply stronger ground shaking along basin edges, particularly along the concealed northeast edge of the Tualatin basin beneath the greater Portland area.

    The proposed East Mulnomah County Groundwater Contamination National Priorities List (NPL) Site is east of Portland, Oregon. Numerous environmental investigations indicate that the groundwater within the proposed NPL site has been contaminated with various chlorinated organic solvents. Because of the complex hydrogeology within the proposed NPL site, it is not possible to determine precisely when each well became contaminated. Based on the available information, the Agency for Toxic Substances and Disease Registry (ATSDR) concludes that the proposed East Multnomah County Groundwater Contamination NPL Site is a public health hazard (past, current, and future). ATSDR representatives made this determination because one contaminated drinking water well has been and is being used by two households.

    Tsunamis are a constant threat to the coasts of our world. Although tsunamis are infrequent along the West coast of the United States, it is possible and necessary to prepare for potential tsunami hazards to minimize loss of life and property. Community awareness programs are important, as they strive to create an informed society by providing education and training. This video about tsunami preparedness in Oregon distinguishes between a local tsunami and a distant event and focus on the specific needs of this region. It offers guidelines for correct tsunami response and community preparedness from local emergency managers, first-responders, and leading experts on tsunami hazards and warnings, who have been working on ways of making the tsunami affected regions safer for the people and communities on a long-term basis. This video was produced by the US Geological Survey (USGS) in cooperation with Oregon Department of Geology and Mineral Industries (DOGAMI).

    The U.S. District Court, District of Oregon, granted the plaintiffs' motion for a preliminary injunction to Measure 16, a ballot measure passed by Oregon voters that authorizes physician-assisted suicide for the terminally ill. The plaintiffs were physicians, terminally ill patients, and residential care facilities, and they sued the state, challenging the constitutionality of Measure 16. The court held that (1) the plaintiffs had standing; (2) serious questions were presented as to whether the measure violated the plaintiffs' freedom of association, freedom of religion, due process, and equal protection rights; and (3) the balance of hardships favored the plaintiffs. The public interest in protecting vulnerable citizens from irreparable harm of death was held to be greater than the hardship to terminally ill patients who want physician-assisted suicide to be immediately available.

  5. Understanding mineral trioxide aggregate/Portland-cement: a review of literature and background factors.

    PubMed

    Steffen, R; van Waes, H

    2009-06-01

    This was to carry out a review of the literature concerning mineral trioxide aggregate (MTA) and Portland cement with regards to clinical, biological and mechanical findings and a possible substitution of MTA through Portland cement for endodontic use. Electronic literature search of scientific papers from January 1993 to January 2009 was carried out on the MEDLINE and Scopus databases using specific key words. In total, 57 papers were identified that dealt with MTA and Portland cement in a relevant way. The review of 50 papers conforming to the applied criteria showed that MTA and Portland cements have the same clinical, biological and mechanical properties. In animal experiments and technical characterisations both materials seemed to have very similar properties. The only difference is bismuth oxide in MTA added for better radio opacity. It seems likely that MTA materials are based on industrial Portland cements mixed with bismuth oxide. More studies, especially some long-term studies comparing MTA and Portland cement, are necessary. The existing literature gives a solid base for clinical studies with Portland cement in order to replace MTA as an endodontic material. Portland cement could be a substitute for most endodontic materials used in primary teeth.

  17. Characterization of Slag, Fly Ash and Portland Cement for Saltstone

    SciTech Connect

    Harbour, J

    2006-02-01

    Batch-to-batch variability in the chemical and physical properties of the fly ash, slag and portland cement (binders) will be an ongoing concern over the many years that salt waste from Tank 50 will be processed into grout at the Saltstone Processing Facility. This batch-to-batch variability in the properties of the binder materials translates to variability in the fresh and cured properties of Saltstone. Therefore, it is important to quantify the batch-to-batch variability of the binder materials and the resultant variation in grout properties. This report is the starting point for that process by providing the baseline (reference point) binder properties to which future batches of binder materials can be compared. For this characterization effort, properties of fly ash, slag and portland cement were obtained and documented in this report. These properties included particle size distribution by laser light scattering and dry sieving, particle size and morphology by scanning electron microscopy, true, aerated and tapped densities, chemical composition, rheological properties of the water based slurries made from individual binder material, and volatility through thermogravimetric analysis and differential thermal analysis. The properties presented in this report also provide a baseline data set to assist in problem solving efforts when or if unanticipated and/or unwanted processing events occur at the Saltstone Processing Facility.

  18. Effect of wastewater on properties of Portland pozzolana cement

    NASA Astrophysics Data System (ADS)

    Babu, G. Reddy

    2017-07-01

    This paper presents the effect of wastewaters on properties of Portland pozzolana cement (PPC). Fourteen water treatment plants were found out in the Narasaraopet municipality region in Guntur district, Andhra Pradesh, India. Approximately, from each plant, between 3500 and 4000 L/day of potable water is selling to consumers. All plants are extracting ground water and treating through Reverse Osmosis (RO) process. During water treatment, plants are discharging approximately 1,00,000 L/day as wastewater in side drains in Narasaraopet municipality. Physical and chemical analysis was carried out on fourteen plants wastewater and distilled water as per producer described in APHA. In the present work, based on the concentrations of constituent's in wastewater, four typical plants i.e., Narasaraopeta Engineering College (NECWW), Patan Khasim Charitable Trust (PKTWW), Mahmadh Khasim Charitable Trust (MKTWW) and Amara (ARWW) were considered. The performance of four plants wastewater on physical properties i.e., setting times, compressive strength, and flexural strength of Portland pozzolana Cement (PPC) were performed in laboratories and compared same with reference specimens i.e., made with Distilled Water (DW) as mixing water. No significant change was observed in initial and finial setting time but setting times of selected wastewaters were retarded as compared to that of reference water. Almost, no change was observed in 90 days compressive and flexural strengths in four plants wastewaters specimens compared to that of reference water specimens. XRD technique was employed to find out main hydration compounds formed in the process.

  19. Differentiating seawater and groundwater sulfate attack in Portland cement mortars

    SciTech Connect

    Santhanam, Manu . E-mail: manus@iitm.ac.in; Cohen, Menashi; Olek, Jan

    2006-12-15

    The study reported in this article deals with understanding the physical, chemical and microstructural differences in sulfate attack from seawater and groundwater. Portland cement mortars were completely immersed in solutions of seawater and groundwater. Physical properties such as length, mass, and compressive strength were monitored periodically. Thermal analysis was used to study the relative amounts of phases such as ettringite, gypsum, and calcium hydroxide, and microstructural studies were conducted by scanning electron microscopy. Portland cement mortars performed better in seawater solution compared to groundwater solution. The difference in performance could be attributed to the reduction in the quantity of the expansive attack products (gypsum and ettringite). The high Cl concentration of seawater could have played an important role by binding the C{sub 3}A to form chloroaluminate compounds, such as Friedel's salt (detected in the microstructural studies), and also by lowering the expansive potential of ettringite. Furthermore, the thicker layer of brucite forming on the specimens in seawater could have afforded better protection against ingress of the solution than in groundwater.
