    The authors report that no mines or active prospects are located within the study area. The only identified resource is perlite. The northern part of the study area has moderate resource potential for zeolites,marekanite (Apache tears), agate, and opaline rock associated with the perlite, and tin. The southern part of the study area has low resource potential for sediment-hosted gold, silver, zinc, copper, and lead. The study area has moderate potential for oil and gas resources. Identified resources of vanadium are present outside the study area and about 800,000 tons of subeconomic metalliferous resources are inferred in the outcrop area, however the potential for undiscovered vanadium resources within the immediately adjacent study area is unknown.

    This report presents the results of a mineral survey of the Meadow Valley Mountains Wilderness Study Area, Lincoln and Clark Counties, Nevada. Rocks of the Meadow Valley Mountains consist of 200- to 600-million-year-old sedimentary rocks in the south and 60-million-year-old and younger volcanic rocks in the north. The structure is typical of the Basin and Range province and is characterized by north-trending normal faults. No patented claims or mining districts are located in the WSA. However, two unpatented claim groups, both believed to be staked for precious metals, are located in the WSA. One of these groups is a large block of about 100 lode claims, less than half of which are in the WSA on the western flank of the range adjacent to Kane Springs Wash. The other group consists of about 20 placer claims in the extreme southeastern corner of the WSA; this group is a part of a larger group of claims in the alluvial fans surrounding the Mormon Mountains to the east of the WSA. The only two reported nonmetallic deposits in the WSA are a perlite deposit in the north and a gypsum deposit in the south. Oil and gas leases cover all of the GRA; no geothermal leases exist in the WSA. Stream-sediment and heavy-mineral-concentrate samples were collected and analyzed spectrographically by the US Geological Survey. The results suggest that thorium and tin mineralization occur in the extreme northern part of the WSA. Geochemical anomalies indicative of detrital mineral occurrences (chromium, lanthanum, and niobium) may exist along the east-central margin of the WSA. Epithermal or skarn-type mineralization, exhibiting the typical metallic suite of molybdenum, tungsten, arsenic, and antimony, may be present along the extreme southwestern border of the WSA. Barite veins may be present. 11 refs., 2 figs., 6 tabs. (ACR)

    Geophysical logs, drilling operations, pump-test data, and water quality determinations are presented for eight wells in the Coyote Spring Valley area of southeastern Nevada. The wells are in an area where thick units of Paleozoic carbonate rock are overlain by Tertiary semiconsolidated basin-fill deposits and Quaternary alluvial deposits. Data collected by the U.S. Geological Survey were augmented with data from previous investigations; however, complete sets of logs and other data are not available for all eight wells. Geophysical data presented included natural-gamma, neutron, gamma-gamma density, caliper, temperature, acoustic, single-point resistance, long- and short-natural resistivity, and spontaneous-potential logs. Drilling penetration rates, lithologic columns, and well construction are also summarized and presented. Measurements of drawdown and recovery during and after constant-discharge pumping periods are also included. Also presented are results of chemical and physical analyses for major-ion chemistry, trace constituents, stable and radioactive isotopes, temperature, pH, specific conductance, and dissolved oxygen.

    Underground Test Area (UGTA) corrective action unit (CAU) groundwater flow and contaminant transport models of the Nevada Test Site (NTS) and vicinity are built upon hydrostratigraphic framework models (HFMs) that utilize the hydrostratigraphic unit (HSU) as the fundamental modeling component. The delineation and three-dimensional (3-D) modeling of HSUs within the highly complex geologic terrain that is the NTS requires a hydrostratigraphic system that is internally consistent, yet flexible enough to account for overlapping model areas, varied geologic terrain, and the development of multiple alternative HFMs. The UGTA CAU-scale hydrostratigraphic system builds on more than 50 years of geologic and hydrologic work in the NTS region. It includes 76 HSUs developed from nearly 300 stratigraphic units that span more than 570 million years of geologic time, and includes rock units as diverse as marine carbonate and siliciclastic rocks, granitic intrusives, rhyolitic lavas and ash-flow tuffs, and alluvial valley-fill deposits. The UGTA CAU-scale hydrostratigraphic system uses a geology-based approach and two-level classification scheme. The first, or lowest, level of the hydrostratigraphic system is the hydrogeologic unit (HGU). Rocks in a model area are first classified as one of ten HGUs based on the rock’s ability to transmit groundwater (i.e., nature of their porosity and permeability), which at the NTS is mainly a function of the rock’s primary lithology, type and degree of postdepositional alteration, and propensity to fracture. The second, or highest, level within the UGTA CAU-scale hydrostratigraphic system is the HSU, which is the fundamental mapping/modeling unit within UGTA CAU-scale HFMs. HSUs are 3-D bodies that are represented in the finite element mesh for the UGTA groundwater modeling process. HSUs are defined systematically by stratigraphically organizing HGUs of similar character into larger HSUs designations. The careful integration of

    Introduction: A regional storm passed through the Las Vegas Valley, Nevada, on December 28-29, 2004, producing up to 2 inches of rain in a 24-hour period. Due to the intense, sustained rainfall, streamflow along Las Vegas Wash was near the record discharges of July 8, 1999. Additional rainfall in December and in January, combined with an early warming trend, resulted in record flooding along Meadow Valley Wash, Muddy River, and Virgin River, January 10-11, 2005 (figs. 1 and 2). On January 7, this warming trend resulted in about a 15?F (degree Fahrenheit) increase over the previous week (fig. 2). This temperature spike, along with further precipitation, caused much of the snow pack in the surrounding mountain ranges to melt and run off into the valleys. These two factors led to the major flood events in Clark and Lincoln Counties during December 2004 and January 2005. Total flood and storm damage for Lincoln County was estimated at $9.4 million and $4.5 million for Clark County (Manning, 2005). Clark County generally is drained by the Las Vegas and Meadow Valley Washes, and the Muddy and Virgin River systems. Las Vegas Valley is drained by Duck Creek, Tropicana Wash (not in fig. 1), Flamingo Wash, Las Vegas Wash, and several smaller tributaries (fig. 1). Water in these drainages generally flows eastward through Las Vegas to Las Vegas Wash and on toward Lake Mead, an impoundment of the Colorado River. The Virgin River originates in southern Utah, flows past Littlefield, AZ, through Mesquite, NV, and into the Overton Arm of Lake Mead. Meadow Valley Wash flows from Ursine, NV, through Caliente, NV, continues southeast through Moapa Valley, and into the Muddy River at Glendale, NV. The Muddy River flows southeast through Moapa Valley into the Overton Arm of Lake Mead (Kane and Wilson, 2000).

    This digital geologic map of the Nevada Test Site (NTS) and vicinity, as well as its accompanying digital geophysical maps, are compiled at 1:100,000 scale. The map compilation presents new polygon (geologic map unit contacts), line (fault, fold axis, metamorphic isograd, dike, and caldera wall) and point (structural attitude) vector data for the NTS and vicinity, Nye, Lincoln, and Clark Counties, Nevada, and Inyo County, California. The map area covers two 30 x 60-minute quadrangles-the Pahute Mesa quadrangle to the north and the Beatty quadrangle to the south-plus a strip of 7.5-minute quadrangles on the east side-72 quadrangles in all. In addition to the NTS, the map area includes the rest of the southwest Nevada volcanic field, part of the Walker Lane, most of the Amargosa Desert, part of the Funeral and Grapevine Mountains, some of Death Valley, and the northern Spring Mountains. This geologic map improves on previous geologic mapping of the same area (Wahl and others, 1997) by providing new and updated Quaternary and bedrock geology, new geophysical interpretations of faults beneath the basins, and improved GIS coverages. Concurrent publications to this one include a new isostatic gravity map (Ponce and others, 1999) and a new aeromagnetic map (Ponce, 1999).

    Geothermal Resource Area 11 includes all of the land in Clark County, Nevada. Within this area are nine geothermal anomalies: Moapa Area, Las Vegas Valley, Black Canyon, Virgin River Narrows, Roger's Springs, Indian Springs, White Rock Springs, Brown's Spring, and Ash Creek Spring. All of the geothermal resources in Clark County have relatively low temperatures. The highest recorded temperature is 145{sup 0}F at Black Canyon. The temperatures of the other resources range from 70 to 90{sup 0}F. Because of the low temperature of the resources and, for the most part, the distance of the resources from any population base, the potential for the development of the resources are considered to be somewhat limited.

    An aeromagnetic map of the Nevada Test Site area was prepared from publicly available aeromagnetic data described by McCafferty and Grauch (1997). Magnetic surveys were processed using standard techniques. Southwest Nevada is characterized by magnetic anomalies that reflect the distribution of thick sequences of volcanic rocks, magnetic sedimentary rocks, and the occurrence of granitic rocks. In addition, aeromagnetic data reveal the presence of linear features that reflect faulting at both regional and local scales.

    The paper reports on the Raymond Mountain Wilderness Study Area which encompasses most of the Sublette Range of western Lincoln County, Wyo. The study area consists of upper Paleozoic and Mesozoic sedimentary rocks that form part of the Idaho-Wyoming-Utah overthrust belt. There are no identified mineral or energy resources in the wilderness study area. The study area has moderate energy resource potential for oil and gas. Mineral resource potential for vanadium and phosphate is low because the Phosphoria Formation is deeply buried beneath the wilderness study area and contains unweathered units having low P{sub 2}O{sub 5} values. The mineral resource potential for coal, other metals, including uranium, high-purity limestone or dolostone, and geothermal energy is low.

    1978-01-01

    In anticipation of increased demand for lithium for energy-related uses, the U.S. Geological Survey has been appraising the lithium resources of the United States and investigating occurrences of lithium. Analyses of samples of chiefly lacustrine rocks of Oligocene age collected by M. R. Mudge near Lincoln, Mont. showed as much as 1,500 ppm lithium. Since then we have sampled the area in greater detail, and have sampled rocks of similar ages in the Helena and Townsend valleys. The lithium-rich beds crop out in a band about 1.3 km long by 0.3 km wide near the head of Beaver Creek, about 14 km northwest of Lincoln, Mont. These beds consist of laminated marlstone, oil shale, carbonaceous shale, limestone, conglomerate, and tuff. Some parts of this sequence average almost 0.1 percent lithium. The lithium-bearing rocks are too low in grade and volume to be economic. Samples of sedimentary rocks of Oligocene age from the Helena and Townsend valleys in the vicinity of Helena, Mont. were generally low in lithium (3-40 ppm). However, samples of rhyolites from the western side of the Helena valley and from the Lava Mountain area were slightly above average in lithium content (6-200 ppm).

    Geochemical sampling in an area of abnormal vegetation in the Cotter basin area, Lewis and Clark County, Montana, shows anomalously high concentrations of Cu, Pb, Ag, Zn, and Au in the soil. The singular presence of a particular plant species growing in the highly anomalous zone merits further investigation for its potential use as an indicator plant for base-metal deposits, buried at shallow depth.

  15. Physical characteristics and quality of water from selected springs and wells in the Lincoln Point-Bird Island area, Utah Lake, Utah

    From February 1991 to October 1992, the U.S. Geological Survey, in cooperation with the Central Utah Water Conservancy District, investigated the hydrology of the Lincoln Point - Bird Island area in the southeast part of Utah Lake, Utah. The investigation included measurements of the discharge of selected springs and measurements of the physical and chemical characteristics of water from selected springs and wells in the LincolnPoint - Bird Island area. This report contains data for twenty-one distinct springs in the study area including two springs beneath the surface of Utah Lake at Bird Island. Data from this study, combined with data from previous studies, indicate that the location of springs in the Lincoln Point - Bird Island area probably is controlled by fractures that are the result of faulting. Measured discharge of springs in the Lincoln Point - Bird Island area ranged from less than 0.01 cubic foot per second to 0.84 cubic foot per second. Total discharge in the study area, including known unmeasured springs and seeps, is estimated to be about 5 cubic feet per second. Reported and measured temperatures of water from springs and wells in the Lincoln Point - Bird Island area ranged from 16.0 degrees Celsius to 36.5 degrees Celsius. Dissolved-solids con-centrations ranged from 444 milligrams per liter to 7,932 milligrams per liter, and pH ranged from 6.3 to 8.1. Physical and chemical characteristics of spring and well water from the west side of Lincoln Point were virtually identical to the physical and chemical characteristics of water from the submerged Bird Island springs, indicating a similar source for the water. Water chemistry, isotope analyses, and geothermometer calculations indicate deep circulation of water discharging from the springs and indicate that the source of recharge for the springs at Lincoln Point and Bird Island does not appear to be localized in the LincolnPoint - Bird Island area.

    A new, revised three-dimensional (3-D) hydrostratigraphic framework model for Frenchman Flat was completed in 2004. The area of interest includes Frenchman Flat, a former nuclear testing area at the Nevada Test Site, and proximal areas. Internal and external reviews of an earlier (Phase I) Frenchman Flat model recommended additional data collection to address uncertainties. Subsequently, additional data were collected for this Phase II initiative, including five new drill holes and a 3-D seismic survey.

  17. Using Landsat ETM+ and ASTER Sensors to Aid the Mineral Assessment of the Desert National Wildlife Refuge, Clark and Lincoln Counties, Nevada

    NASA Astrophysics Data System (ADS)

    Cramer, Timothy F.

    The Desert National Wildlife Refuge in southern Nevada has been selected for remote sensing analysis as part of a mineral assessment required for renewal of mineral withdrawal. The area of interest is nearly 3,000 km2 and covers portions of 5 different ranges with little to no infrastructure. Assessing such a large area using traditional field methods is very time intensive and expensive. The study described here serves as a pilot study, testing the capability of Landsat ETM+ and ASTER satellite imagery to remotely identify areas of potentially mineralized lithologies. This is done by generating a number of band ratio, band index, and mineral likelihood maps identifying 5 key mineral classes (silica, clay, iron oxide, dolomite and calcite), which commonly have patterned zonation around ore deposits. When compiled with available geologic and geochemical data sets, these intermediate products can provide guidance for targeted field evaluation and exploration. Field observations and spectral data collected in the laboratory can then be integrated with ASTER imagery to guide a Spectral Angle Mapper algorithm to generate a distribution map of the five mineral classes. The methods presented found the ASTER platform to be capable of remotely assessing the distribution of various lithologies and the mineral potential of large, remote areas. Furthermore areas of both high and low potential for ore deposits can be identified and used to guide field evaluation and exploration. Remote sensing studies of this caliber can be performed relatively quickly and inexpensively resulting in datasets, which can result in more accurate mapping and the identification of both lithologic boundaries and previously unidentified alteration associated with mineralization. Future mineral assessments and exploration activity should consider similar studies prior to field work.

    An isostatic gravity map of the Nevada Test Site area was prepared from publicly available gravity data (Ponce, 1997) and from gravity data recently collected by the U.S. Geological Survey (Mankinen and others, 1999; Morin and Blakely, 1999). Gravity data were processed using standard gravity data reduction techniques. Southwest Nevada is characterized by gravity anomalies that reflect the distribution of pre-Cenozoic carbonate rocks, thick sequences of volcanic rocks, and thick alluvial basins. In addition, regional gravity data reveal the presence of linear features that reflect large-scale faults whereas detailed gravity data can indicate the presence of smaller-scale faults.

    A Mineral resource survey was conducted in 1987 by the U.S. Geological Survey and the U.S. Bureau of Mines to evaluate mineral resources (known) and mineral resource potential (undiscovered) of the Sleeping Giant Wilderness Study Area (MT-075-111) in Lewis and Clark County, Montana. The only economic resource in the study area is an inferred 1.35-million-ton reserve of decorative stone (slate); a small gold placer resource is subeconomic. A high resource potential for decorative slate exists directly adjacent to the area of identified slate resource and in the northeastern part of the study area. The rest of the study area has a low potential for decorative slate. The westernmost part of the study area has a moderate resource potential for copper and associated silver in state-bound deposits in green beds and limestone; potential is low in the rest of the study are. The study area has a low resource potential for sapphires in placer deposits, gold in placer deposits (exclusive of subeconomic resource mentioned above), phosphate in the Spokane Formation, diatomite in lake deposits, uranium, oil, gas, geothermal energy, and no resource potential for phosphate in the Phosphoria Formation.

    Ground water moving through permeable Paleozoic carbonate rocks represents the most likely pathway for migration of radioactive contaminants from nuclear weapons testing at the Nevada Test Site, Nye County, Nevada. The strontium isotopic composition (87Sr/86Sr) of ground water offers a useful means of testing hydrochemical models of regional flow involving advection and reaction. However, reaction models require knowledge of 87Sr/86Sr data for carbonate rock in the Nevada Test Site vicinity, which is scarce. To fill this data gap, samples of core or cuttings were selected from 22 boreholes at depth intervals from which water samples had been obtained previously around the Nevada Test Site at Yucca Flat, Frenchman Flat, Rainier Mesa, and Mercury Valley. Dilute acid leachates of these samples were analyzed for a suite of major- and trace-element concentrations (MgO, CaO, SiO2, Al2O3, MnO, Rb, Sr, Th, and U) as well as for 87Sr/86Sr. Also presented are unpublished analyses of 114 Paleozoic carbonate samples from outcrops, road cuts, or underground sites in the Funeral Mountains, Bare Mountain, Striped Hills, Specter Range, Spring Mountains, and ranges east of the Nevada Test Site measured in the early 1990's. These data originally were collected to evaluate the potential for economic mineral deposition at the potential high-level radioactive waste repository site at Yucca Mountain and adjacent areas (Peterman and others, 1994). Samples were analyzed for a suite of trace elements (Rb, Sr, Zr, Ba, La, and Ce) in bulk-rock powders, and 87Sr/86Sr in partial digestions of carbonate rock using dilute acid or total digestions of silicate-rich rocks. Pre-Tertiary core samples from two boreholes in the central or western part of the Nevada Test Site also were analyzed. Data are presented in tables and summarized in graphs; however, no attempt is made to interpret results with respect to ground-water flow paths in this report.

    Water samples from representative shallow wells in Lincoln, Mont., were collected in March and June 1979 for analysis to evaluate changes in quality since 1974-75 and possible contamination by domestic or agricultural waste. All samples were suitable for drinking water with respect to the constituents tested. Tests for fecal coliform bacteria were negative. The concentrations of dissolved solids, composed mainly of calcium, magnesium, bicarbonate, and sulfate, were less than 300 milligrams per liter. Concentrations of sodium, potassium, and chloride were 3.5 milligrams per liter or less. From March to June, the maximum concentration of nitrate plus nitrite nitrogen (as N) declined from 0.57 to 0.29 milligram per liter and the mean concentrations declined from 0.16 to 0.11 milligram per liter, probably as a result of dilution of ground water by snowmelt. The concentrations in samples from the same sites generally were lower in 1979 than in 1974-75. Isolation of sewage effluent in shallow zones by hardpan, consumption of nutrients by abundant phreatophytes, filtration of bacteria by the soil or aquifer, and dilution by underflow and recharge evidently combine to maintain the quality of the well waters within acceptable limits.

    When Abraham Lincoln delivered the Gettysburg Address, he was weak and dizzy; his face had a ghastly colour. That evening on the train to Washington, DC, he was febrile and weak, and suffered severe headaches. The symptoms continued; back pains developed. On the fourth day of the illness, a widespread scarlet rash appeared that soon became vesicular. By the tenth day, the lesions itched and peeled. The illness lasted three weeks. The final diagnosis, a touch of varioloid, was an old name for smallpox that was later used in the 20th century to denote mild smallpox in a partially immune individual. It was unclear whether Lincoln had been immunized against smallpox. Indeed, this review suggests that Lincoln had unmodified smallpox and that Lincoln's physicians tried to reassure the public that Lincoln was not seriously ill. Indeed, the successful conclusion of the Civil War and reunification of the country were dependent upon Lincoln's presidency. PMID:17551612

The study area contains no identified mineral resources and has no areas of high mineral resource potential. However, five areas that make up 20 percent of the study area have a moderate potential either for undiscovered silver, gold, lead, copper, and zinc resources in small vein deposits; for lanthanum and other rare-earth elements, uranium, thorium, and niobium in medium-size carbonatite bodies and dikes; for tungsten and copper in small- to medium-size vein deposits; or for silver and gold in small vein or breccia-pipe deposits. Six areas that makeup 24 percent of the study area have an unknown resource potential either for gold, silver, lead, and copper in small vein deposits; for gold, silver, lead, zinc, copper, and arsenic in small vein or breccia-pipe deposits; for lanthanum and other rare-earth elements, uranium, thorium, and niobium in medium-size carbonatite bodies and dikes; or for tungsten and copper in small vein deposits.

  6. Potential flood and debris hazards at Cottonwood Cove, Lake Mead National Recreation Area, Clark County, Nevada

    USGS Publications Warehouse

    Moosburner, Otto

    1981-01-01

    At Cottonwood Cove, Nevada, most of the existing dikes at the recreation sites are effective in diverting and routing floodflows, up to and including the 100-year flood, away from people and facilities. The dikes across Ranger Residence Wash and Access Road Wash at the mouth divert floods up to the 50-year recurrence interval away from residential areas. Flow and debris damage in protected areas will be relatively minor minor for floods including the 100-year flood, whereas damage caused by sediment deposition at the mouths of the washes near Lake Mohave could be significant for floods equal to or less than the 100-year flood. The extreme flood, a flood meteorologically and hydrologically possible but so rare as to preclude a frequency estimate, could cause great damage and possible loss of life. The present dikes would be topped or breached by such flooding. (USGS)

  9. Was Abraham Lincoln gay?

    PubMed

    Ferguson, Michael

    2010-01-01

    Scholars and historians are blind to Lincoln's same-sex inclinations in part because of a personal aversion to male homosexuality, but more importantly because they fail to perceive the vast differences between the sexual culture of antebellum America and that of our own time, especially in regard to male-male physical and emotional intimacy. This article brings those differences to light and sets Lincoln's life in the context of the sexual culture of his own time. This enables one to see that Lincoln's same-sex sexuality was not only unproblematic, but commonplace, if not typical, in his day. Revising the Myth of Lincoln in regard to his same-sex inclinations will have a positive effect on contemporary culture, especially on the education and socialization of young boys. PMID:20924927

    This report presents the results of a geologic and mineral survey of wilderness study areas MT-075-101 through MT-075-110 Headwaters Resource Area, east of the Bob Marshall Wilderness, Teton and Lewis and Clark Counties, Montana. The report also contains the results of a US Bureau of Mines mineral surevy of wilderness study areas MT-075-102, 105, 106, 107, and part of 110, Teton and Lewis and Clark Counties, Montana. The 10 US Bureau of Land Management areas have a high potential for hydrocarbon resources, mainly gas. The areas contain potential source and reservoir rocks and are in a structural setting favorable for hydrocarbon generation and accumulation. Seismic data are necessary for each area to determine if potential structural traps are present. Area 110 has a low potential for lead deposits. A mineral survey conducted by the US Bureau of Mines in 1983 indicated no identified mineral resources are in study areas MT-075-102, 105, 106, 107, and 110. 35 refs., 6 figs., 5 tabs. (ACR)

  13. Total arsenic accumulation in yabbies (Cherax destructor Clark) exposed to elevated arsenic levels in Victorian gold mining areas, Australia.

    PubMed

    Williams, Gemma; West, Jan M; Snow, Elizabeth T

    2008-06-01

    Arsenic is a proven carcinogen often found at high concentrations in association with gold and other heavy metals. The freshwater yabby, Cherax destructor Clark (Decapoda, Parastacidae), is a ubiquitous species native to Australia's central and eastern regions, with a growing international commercial market. However, in this region of Australia, yabby farmers often harvest organisms from old mine tailings dams with elevated environmental arsenic levels. Yabbies exposed to elevated environmental arsenic were found to accumulate and store as much as 100 microg/g arsenic in their tissues. The accumulation is proportional to the concentration of arsenic in the sediment and is high enough to be of concern for people who eat the yabbies. A comparison of arsenic levels in wild and lab-fed animals also was performed. Although there was no significant difference in the level of arsenic in the various organs of the wild animals, the animals purchased from a yabby farm showed a significantly higher arsenic concentration in their hepatopancreas (3.7 +/- 0.9 microg/g) compared to other organs (0.6-1.8 microg/g). Furthermore, after a 40-d exposure to food containing 200 to 300 microg/g inorganic arsenic, arsenate (As[V])-exposed animals showed a significant increase in tissue-specific arsenic accumulation, whereas arsenite (As[III])-exposed animals showed a lower, nonsignificant increase in As uptake, primarily in the hepatopancreas. These results have important implications for yabby growers and consumers alike. PMID:18198937

    The author has identified the following significant results. A structural model which relates strike-slip deformation to Basin Range extensional tectonics was formulated on the basis of analysis and interpreatation of ERTS-1 MSS imagery over southern Lincoln County, Nevada. Study of published geologic data and field reconnaissance of key areas has been conducted to support the ERTS-1 data interpretation. The structural model suggests that a left-lateral strike-slip fault zone, called the Pahranagat Shear System, formed as a transform fault separating two areas of east-west structural extension.

    Berkas, W.R.; Komor, S.C.

    1996-01-01

    The Garrison Diversion Unit project was authorized as part of the Pick-Sloan Missouri River Basin program to divert water from Lake Sakakawea to irrigation areas in North Dakota. A special GarrisonCommission was created to evaluate an environmental concern that return flow from the irrigation areas might contain metals in toxic concentrations. This report summarizes the results of detailed investigations of the Turtle Lake, New Rockford, Harvey Pumping, Lincoln Valley, and LaMoure irrigation areas. A total of 223 soil samples were collected from the irrigation areas and analyzed for elemental composition. Water extractions were done on 40 of the 223 soil samplesusing a 1:5 soil-to-water extraction method, and the solution from the extraction was analyzed for elemental composition. A total of 52 ground-water samples were collected and analyzed for inorganic constituents and organic carbon. Average arsenic concentrations in the entire soil column ranged from 1.0 milligram per kilogram in the Harvey Pumping irrigation area to 70milligrams per kilogram in the New Rockford irrigation area. Average selenium concentrations ranged from less than 0.1 milligram per kilogramin the Turtle Lake, New Rockford, Harvey Pumping, and Lincoln Valley irrigation areas to 6.0 milligrams per kilogram in the Turtle Lakeirrigation area. In the Turtle Lake irrigation area, average arsenic and selenium concentrations generally increased with depth through the topsoil, oxidized soil, and transition soil but decreased in the reduced soil at the bottom of the sampled horizons.Average arsenic concentrations in the New Rockford irrigation area follow the same pattern as in the Turtle Lake irrigation area, but selenium concentrations do not show a clear pattern of variation with depth. In the Harvey Pumping and Lincoln Valley irrigation areas, arsenic andselenium concentrations do not appear to vary systematically with depth. No correlation is shown between the concentrations in soils and

    2014-01-01

    DigitalGlobe’s QuickBird satellite high-resolution multispectral imagery was classified by using Visual Learning Systems’ Feature Analyst feature extraction software to produce land-cover data sets for the Red Rock Canyon National Conservation Area and the Coyote Springs, Piute-Eldorado Valley, and Mormon Mesa Areas of Critical Environmental Concern in Clark County, Nevada. Over 1,000 vegetation field samples were collected at the stand level. The field samples were classified to the National Vegetation Classification Standard, Version 2 hierarchy at the alliance level and above. Feature extraction models were developed for vegetation on the basis of the spectral and spatial characteristics of selected field samples by using the Feature Analyst hierarchical learning process. Individual model results were merged to create one data set for the Red Rock Canyon National Conservation Area and one for each of the Areas of Critical Environmental Concern. Field sample points and photographs were used to validate and update the data set after model results were merged. Non-vegetation data layers, such as roads and disturbed areas, were delineated from the imagery and added to the final data sets. The resulting land-cover data sets are significantly more detailed than previously were available, both in resolution and in vegetation classes.

  1. Abraham Lincoln and the insanity plea.

    PubMed

    Spiegel, A D

    1994-06-01

    A confederate civilian physician shot and killed a white Union officer who was drilling Negro troops in Norfolk, Virginia. With no question as to guilt, President Abraham Lincoln decided to have a medical expert conduct a professional sanity/insanity examination. Documentation indicates that legal and political factors may have influenced Lincoln's decision. As a lawyer, Lincoln prosecuted a case where the insanity plea was used as a defense. Two influential Cabinet members, William H. Seward and Edwin M. Stanton, also had legal experience involving the insanity plea. Politically, Lincoln faced serious issues such as the draft riots, the military necessity to recruit slaves into the army, the impact of Union Negro soldiers upon the border states, the morale and discipline of the army and the upcoming presidential election. Upon Seward's recommendation, Lincoln chose a physician who had a reputation for finding the accused sane and who did so in this case. As the southern physician was hanged, Lincoln's means achieved the desired legal and political ends. PMID:8089270

    This report presents estimated daily and cumulative loads of suspended sediment and selected trace elements transported during water year 2008 at three streamflow-gaging stations that bracket the Milltown Reservoir project area in the upper Clark Fork basin of western Montana. Milltown Reservoir is a National Priorities List Superfund site where sediments enriched in trace elements from historical mining and ore processing have been deposited since the construction of Milltown Dam in 1907. Milltown Dam was breached on March 28, 2008, as part of Superfund remedial activities to remove the dam and contaminated sediment that had accumulated in Milltown Reservoir. The estimated loads transported through the project area during the periods before and after the breaching of Milltown Dam, and for the entire water year 2008, were used to quantify the net gain or loss (mass balance) of suspended sediment and trace elements within the project area during the transition from a reservoir environment to a free-flowing river. This study was done in cooperation with the U.S. Environmental Protection Agency. Streamflow during water year 2008 compared to long-term streamflow, as represented by the record for Clark Fork above Missoula (water years 1930-2008), generally was below normal (long-term median) from about October 2007 through April 2008. Sustained runoff started in mid-April, which increased flows to near normal by mid-May. After mid-May, flows sharply increased to above normal, reaching a maximum daily mean streamflow of 16,800 cubic feet per second (ft3/s) on May 21, which essentially equaled the long-term 10th-exceedance percentile for that date. Flows substantially above normal were sustained through June, then decreased through the summer and reached near-normal by August. Annual mean streamflow during water year 2008 (3,040 ft3/s) was 105 percent of the long-term mean annual streamflow (2,900 ft3/s). The annual peak flow (17,500 ft3/s) occurred on May 21 and was 112

    Examination of 2 life masks of Abraham Lincoln's face was performed by means of 3-dimensional laser surface scanning. This technique enabled documentation and analysis of Lincoln's facial contours and demonstrated his marked facial asymmetry, particularly evident in the smaller left superior orbital rim. This may have led to retroplacement of the trochlea on the left side, leading, in turn, to the mild superior oblique paresis that was manifested intermittently during adulthood. PMID:17698764

    Vertical-bore, geothermal heat pumps (GHPs) have been providing heating and cooling to four new elementary schools located in Lincoln, Nebraska since 1995. According to representatives of the local utility and school district, the systems are providing a comfortable, complaint-free environment with utility costs that are nearly half of that of other schools in the district. Performance data collected from on-site energy management systems and district billing and utility records for all fifty schools in the Lincoln district indicate that only five consume less energy than the best performing GHP school; however these five cool less than 10% of their total floor area, while the GHP schools cool 100% of their floor area. When compared to other new schools (with similar ventilation loads), the GHP schools used approximately 26% less source energy per square foot of floor area. Variations in annual energy performance are evident among the four GHP schools, however, together they still consume less source energy than 70% of all schools in the district. These variations are most likely due to operational differences rather than installed equipment, building orientation, or environmental (bore field) conditions.

    J. (Jeannette) Virginia Lincoln died on 1 August 2003 of natural causes at age 87. She was a pioneer in space weather forecasting and was instrumental in establishing the World Data Center-A for Solar-Terrestrial Physics (WDC-A for STP) at the National Oceanic and Atmospheric Administration's (NOAA) National Geophysical Data Center (NGDC). Lincoln received a U.S. Department of Commerce Gold Medal for Distinguished Service in 1973 for outstanding accomplishments and leadership. She was elected a Fellow of the American Geophysical Union, a Fellow of the American Association for the Advancement of Science, and a Fellow of the Society of Women Engineers. A physicist, she served as Division Chief of the Solar-Terrestrial Physics Division (STPD) and Director of WDC-A for STP from 1966 until her retirement in 1980. Virginia was born on Labor Day, 7 September 1915, in Ames, Iowa, to Rush B. Lincoln and Jeannette Bartholomew Lincoln. Her father, Rush B. Lincoln (b. 1881, d. 1977 at age 95), served as a Major General in the U.S. Air Force. He was a direct descendant of the brother of President Abraham Lincoln. Her mother Jeannette Bartholomew Lincoln (d. 1986 at age 104) taught Chemistry at Iowa State University. Her brother, Rush B. Lincoln, Jr. (d. 2002), was five years older. Her grandfather Lincoln fought in the Civil War as a Confederate Captain. Virginia was immersed in military life and continued many contacts and visited military installations throughout her life. Her parents lived with her until their deaths. She enjoyed the perks of being a General's daughter, actively participating in her parent's lives, and served as caregiver in their declining years. Influenced by her Army background, she developed a strong assertive personality and good problem-solving capabilities. She received a bachelor's degree in physics from Wellesley College in 1936 and a master's degree from Iowa State University in 1938. She was an instructor in household equipment at Iowa State from

    2009-10-20

    An autosomal dominant genetic disorder, type 5 spinocerebellar ataxia (SCA5), occurs in multiple descendants of one paternal uncle and one paternal aunt of President Abraham Lincoln. It has been suggested that Lincoln himself had the disease and that his DNA should be tested for an SCA5-conferring gene. Herein, I review the pertinent phenotypes of Lincoln, his father, and his paternal grandmother, and conclude that 1) Lincoln's father did not have SCA5, and, therefore, that Lincoln was not at special risk of the disease; 2) Lincoln had neither subclinical nor visible manifestations of SCA5; 3) little evidence suggests SCA5 is a "Lincolnian" disorder; and 4) without additional evidence, Lincoln's DNA should not be tested for SCA5.

  11. Scoping of Flood Hazard Mapping Needs for Lincoln County, Maine

    USGS Publications Warehouse

    Schalk, Charles W.; Dudley, Robert W.

    2007-01-01

    Background The Federal Emergency Management Agency (FEMA) developed a plan in 1997 to modernize the FEMA flood mapping program. FEMA flood maps delineate flood hazard areas in support of the National Flood Insurance Program (NFIP). FEMA's plan outlined the steps necessary to update FEMA's flood maps for the nation to a seamless digital format and streamline FEMA's operations in raising public awareness of the importance of the maps and responding to requests to revise them. The modernization of flood maps involves conversion of existing information to digital format and integration of improved flood hazard data as needed. To determine flood mapping modernization needs, FEMA has established specific scoping activities to be done on a county-by-county basis for identifying and prioritizing requisite flood-mapping activities for map modernization. The U.S. Geological Survey (USGS), in cooperation with FEMA and the Maine Floodplain Management Program (MFMP) State Planning Office, began scoping work in 2006 for Lincoln County. Scoping activities included assembling existing data and map needs information for communities in Lincoln County, documentation of data, contacts, community meetings, and prioritized mapping needs in a final scoping report (this document), and updating the Mapping Needs Update Support System (MNUSS) database with information gathered during the scoping process. The average age of the FEMA floodplain maps in Lincoln County, Maine is at least 17 years. Many of these studies were published in the mid- to late-1980s, and some towns have partial maps that are more recent than their study. However, in the ensuing 15-20 years, development has occurred in many of the watersheds, and the characteristics of the watersheds have changed with time. Therefore, many of the older studies may not depict current conditions nor accurately estimate risk in terms of flood heights or flood mapping.

  14. Reconnaissance of surface-water and ground-water quality at the Lincoln Boyhood National Memorial near Lincoln City, Indiana, 2001-02

    USGS Publications Warehouse

    Buszka, Paul M.; Fowler, Kathleen K.

    2005-01-01

    In cooperation with the National Park Service, the U.S. Geological Survey investigated water quality of key water bodies at the Lincoln Boyhood National Memorial near Lincoln City in southwestern Indiana. The key water bodies were a stock pond, representing possible nonpoint agricultural effects on water quality; an ephemeral stream, representing the water quality of drainage from forested areas of the park; parking-lot runoff, representing water quality related to roads and parking lots; an unnamed ditch below the parking lot, representing the water quality of drainage from the parking lot and from an adjacent railroad track; and Lincoln Spring, a historical ground-water source representing ground-water conditions near a former diesel-fuel-spill site along a rail line. Water samples were analyzed for pH, temperature, specific conductance, and dissolved oxygen and for concentrations of selected major ions and trace metals, nutrients, organic constituents, and Escherichia coli bacteria. Surface-water-quality data of water samples from the park represent baseline conditions for the area in relation to the data available from previous studies of area streams. Specific-conductance values and concentrations of most major ions and various nutrients in surface-water samples from the park were smaller than those reported for samples collected in other USGS studies in areas adjacent to the park. Water-quality-management issues identified by this investigation include potentially impaired water quality from parking-lot runoff, unknown effects on surface-water quality from adjacent railroads, and the potential impairment of water quality in Lincoln Spring from human influences. Parking-lot runoff is a source of calcium, alkalinity, iron, lead, and organic carbon in the water samples from the unnamed ditch. Detection of small concentrations of petroleum hydrocarbons in water from Lincoln Spring could indicate residual contamination from a 1995 diesel-fuel spill and cleanup

  15. Abraham Lincoln and the global economy.

    PubMed

    Hormats, Robert D

    2003-08-01

    Abraham Lincoln would have well understood the challenges facing many modern emerging nations. In Lincoln's America, as in many developing nations today, sweeping economic change threatened older industries, traditional ways of living, and social and national cohesion by exposing economies and societies to new and powerful competitive forces. Yet even in the midst of the brutal and expensive American Civil war--and in part because of it--Lincoln and the Republican Congress enacted bold legislation that helped create a huge national market, a strong and unified economy governed by national institutions, and a rising middle class of businessmen and property owners. Figuring out how to maximize the benefits of globalization while minimizing its disruptions is a formidable challenge for policy makers. How do you expand opportunities for the talented and the lucky while making sure the rest of society doesn't fall behind? It may be helpful to look at the principles that informed the policies that Lincoln and the Republican Congress instituted after they came to power in 1861: Facilitate the upward mobility of low- and middle-income groups to give them a significant stake in the country. Emphasize the good of the national economy over regional interests. Affirm the need for sound government institutions to temper the dynamics of the free enterprise system. Tailor policies to the national situation. Realize that a period of turmoil may present a unique opportunity for reform. These principles drove the reforms that helped Americans cope with and benefit from rapid technological advances and the fast integration of the American economy in the nineteenth century. They may be instructive to today's policy makers who are struggling to help their own citizens integrate into the fast-changing global economy of the twenty-first century. PMID:12884668

  8. Founding events influence genetic population structure of sockeye salmon (Oncorhynchus nerka) in Lake Clark, Alaska

    USGS Publications Warehouse

    Ramstad, K.M.; Woody, C.A.; Sage, G.K.; Allendorf, F.W.

    2004-01-01

    Bottlenecks can have lasting effects on genetic population structure that obscure patterns of contemporary gene flow and drift. Sockeye salmon are vulnerable to bottleneck effects because they are a highly structured species with excellent colonizing abilities and often occupy geologically young habitats. We describe genetic divergence among and genetic variation within spawning populations of sockeye salmon throughout the Lake Clark area of Alaska. Fin tissue was collected from sockeye salmon representing 15 spawning populations of Lake Clark, Six-mile Lake, and Lake Iliamna. Allele frequencies differed significantly at 11 microsatellite loci in 96 of 105 pairwise population comparisons. Pairwise estimates of FST ranged from zero to 0.089. Six-mile Lake and Lake Clark populations have historically been grouped together for management purposes and are geographically proximate. However, Six-mile Lake populations are genetically similar to Lake Iliamna populations and are divergent from Lake Clark populations. The reduced allelic diversity and strong divergence of Lake Clark populations relative to Six-mile Lake and Lake Iliamna populations suggest a bottleneck associated with the colonization of Lake Clark by sockeye salmon. Geographic distance and spawning habitat differences apparently do not contribute to isolation and divergence among populations. However, temporal isolation based on spawning time and founder effects associated with ongoing glacial retreat and colonization of new spawning habitats contribute to the genetic population structure of Lake Clark sock-eye salmon. Nonequilibrium conditions and the strong influence of genetic drift caution against using estimates of divergence to estimate gene flow among populations of Lake Clark sockeye salmon.

    The upper Clark Fork River in northwestern Montana has received mining wastes from the Butte and Anaconda areas since 1880. These wastes have contaminated areas of the river bed and floodplain with tailings and heavy metal sludge, resulting in elevated concentration of metals in surface water, sediments, and biota. Rainbow trout Oncorhynchus mykiss were exposed immediately after hatching for 91 d to cadmium, copper, lead, and zinc in water at concentrations simulating those in Clark Fork River. From exogenous feeding (21 d posthatch) through 91 d, fry were also fed benthic invertebrates from the Clark Fork River that contained elevated concentrations of arsenic, cadmium, copper, and lead. Evaluations of different combinations of diet and water exposure indicated diet-borne metals were more important than water-borne metals - at the concentrations we tested - in reducing survival and growth of rainbow trout. Whole-body metal concentrations ([mu]g/g, wet weight) at 91 d in fish fed Clark Fork invertebrates without exposure to Clark Fork water were arsenic, 1.4; cadmium, 0.16; and copper, 6.7. These were similar to concentrations found in Clark Fork River fishes. Livers from fish on the high-metals diets exhibited degenerative changes and generally lacked glycogen vacuolation. Indigenous Clark Fork River invertebrates provide a concentrated source of metals for accumulation into young fishes, and probably were the cause of decreased survival and growth of age-0 rainbow trout in our laboratory exposures. 30 refs., 8 figs., 4 tabs.

    After only about a year of law practice, Abraham Lincoln participated in his first murder trial. Dr. Jacob M. Early was shot and killed in a bitter political imbroglio. Lincoln joined a defense team of highly accomplished litigators. Despite his having the least legal experience, he was selected to give the defense summation. In his argument, he spoke to the jury in a conversational tone making his point that Dr. Early had a deadly weapon in his hands, namely an upraised wooden chair, when he was shot. His self-defense plea indicated that Henry B. Truett, the defendant, truly believed that he was in danger of being crushed by the upraised chair. Interestingly, Lincoln knew both the defendant and the murdered physician. He handled litigation for the former and served in the Black Hawk War under the command of the latter. Furthermore Lincoln knew at least five of the jurors. PMID:15989212

    1997-12-01

    During an 1857 trial, the defence claimed that the accused should be absolved of wilful murder because an overdose of chloroform during surgery induced insanity. In a rare appearance as a prosecutor, Abraham Lincoln tried the case for the State of Illinois. Expert medical witnesses testified about the side effects of chloroform and chloroform-induced insanity. Significantly, Lincoln was not knowledgeable about medical jurisprudence and overlooked potential sources of evidence and expert witnesses. Defence lawyers presented an impressive array of physicians to testify about insanity, about chloroform and about the results of an overdosage during anaesthesia. Considering the state of scientific knowledge at the time, the trial was notable. PMID:11619819

  14. Abraham Lincoln, psychotherapist to the nation: the use of metaphors.

    PubMed

    Leetz, K L

    1997-01-01

    Metaphors are widely utilized in psychotherapy to effect change in patients. Psychotherapeutic metaphors, in their various versions, may offer new choices and ways of viewing oneself to the patient which are more palatable than straight discussions or sterile insights. By addressing resistances indirectly, metaphors can be an effective tool for the therapist to use, regardless of theoretical orientation. Abraham Lincoln, a master of metaphor, utilized this tool effectively in dealing with crises and the ultimate fragmentation, disunion of the national identity. The author argues that Lincoln was able to address complex issues (such as slavery, liberty, nationhood, union, and conduct of the war) with metaphors, much as a skilled psychotherapist addresses complex issues within his or her purview. Abraham Lincoln effectively disarmed his critics, established a means of communication with the people, and sought to make his points in an understandable nonconfrontational fashion. These are skills highly valued by psychotherapists. One might say that Abraham Lincoln conducted psychotherapy on a national scale. Without formal training, he was ultimately able to create a new and more stable sense of national self using a metaphorical approach. PMID:9139547

  9. Lincoln estimates of mallard (Anas platyrhynchos) abundance in North America

    Alisauskas, Ray T; Arnold, Todd W; Leafloor, James O; Otis, David L; Sedinger, James S

    2014-01-01

    Estimates of range-wide abundance, harvest, and harvest rate are fundamental for sound inferences about the role of exploitation in the dynamics of free-ranging wildlife populations, but reliability of existing survey methods for abundance estimation is rarely assessed using alternative approaches. North American mallard populations have been surveyed each spring since 1955 using internationally coordinated aerial surveys, but population size can also be estimated with Lincoln's method using banding and harvest data. We estimated late summer population size of adult and juvenile male and female mallards in western, midcontinent, and eastern North America using Lincoln's method of dividing (i) total estimated harvest, , by estimated harvest rate, , calculated as (ii) direct band recovery rate, , divided by the (iii) band reporting rate, . Our goal was to compare estimates based on Lincoln's method with traditional estimates based on aerial surveys. Lincoln estimates of adult males and females alive in the period June–September were 4.0 (range: 2.5–5.9), 1.8 (range: 0.6–3.0), and 1.8 (range: 1.3–2.7) times larger than respective aerial survey estimates for the western, midcontinent, and eastern mallard populations, and the two population estimates were only modestly correlated with each other (western: r = 0.70, 1993–2011; midcontinent: r = 0.54, 1961–2011; eastern: r = 0.50, 1993–2011). Higher Lincoln estimates are predictable given that the geographic scope of inference from Lincoln estimates is the entire population range, whereas sampling frames for aerial surveys are incomplete. Although each estimation method has a number of important potential biases, our review suggests that underestimation of total population size by aerial surveys is the most likely explanation. In addition to providing measures of total abundance, Lincoln's method provides estimates of fecundity and population sex ratio and could be used in integrated population

    Presents an obituary for Clark E. Moustakas. Clark E. Moustakas was a consummate educator and a true model of the tenets and values of humanistic psychology, a movement he cofounded in the late 1950s with other pioneers in American psychology, including Abraham Maslow and Carl Rogers. This movement, recognized as the "third force" in psychology, had a significant impact in the 1960s and 1970s and became an important component of mainstream practice. Moustakas produced a prolific and influential body of work. He embraced solitude as a time of reflection and did not enjoy notoriety. While he inhabited many roles-professor, scholar, clinician, and author-engagement with others in the moment was always the most essential element in his life. He was a gentle man, full of energy and spirit, exuding warmth and focused attention. In his company, one was immediately struck by his earnestness and caring. People from all over the world respected his expertise and sought his advice. To have this impact and to have informed the field in so many ways is a remarkable accomplishment. PMID:23895613

  17. Clark's Nutcracker Breeding Season Space Use and Foraging Behavior.

    PubMed

    Schaming, Taza D

    2016-01-01

    Considering the entire life history of a species is fundamental to developing effective conservation strategies. Decreasing populations of five-needle white pines may be leading to the decline of Clark's nutcrackers (Nucifraga columbiana). These birds are important seed dispersers for at least ten conifer species in the western U.S., including whitebark pine (Pinus albicaulis), an obligate mutualist of Clark's nutcrackers. For effective conservation of both Clark's nutcrackers and whitebark pine, it is essential to ensure stability of Clark's nutcracker populations. My objectives were to examine Clark's nutcracker breeding season home range size, territoriality, habitat selection, and foraging behavior in the southern Greater Yellowstone Ecosystem, a region where whitebark pine is declining. I radio-tracked Clark's nutcrackers in 2011, a population-wide nonbreeding year following a low whitebark pine cone crop, and 2012, a breeding year following a high cone crop. Results suggest Douglas-fir (Pseudotsuga menziesii) communities are important habitat for Clark's nutcrackers because they selected it for home ranges. In contrast, they did not select whitebark pine habitat. However, Clark's nutcrackers did adjust their use of whitebark pine habitat between years, suggesting that, in some springs, whitebark pine habitat may be used more than previously expected. Newly extracted Douglas-fir seeds were an important food source both years. On the other hand, cached seeds made up a relatively lower proportion of the diet in 2011, suggesting cached seeds are not a reliable spring food source. Land managers focus on restoring whitebark pine habitat with the assumption that Clark's nutcrackers will be available to continue seed dispersal. In the Greater Yellowstone Ecosystem, Clark's nutcracker populations may be more likely to be retained year-round when whitebark pine restoration efforts are located adjacent to Douglas-fir habitat. By extrapolation, whitebark pine restoration

  19. Abraham Lincoln's marfanoid mother: the earliest known case of multiple endocrine neoplasia type 2B?

    PubMed

    Sotos, John G

    2012-07-01

    The nature and cause of President Abraham Lincoln's unusual physical features have long been debated, with the greatest attention directed at two monogenic disorders of the transforming growth factor β system: Marfan syndrome and multiple endocrine neoplasia type 2B. The present report examines newly discovered phenotypic information about Lincoln's biological mother, Nancy Hanks Lincoln, and concludes that (a) Lincoln's mother was skeletally marfanoid, (b) the President and his mother were highly concordant for the presence of numerous facial features found in various transforming growth factor β disorders, and (c) Lincoln's mother, like her son, had hypotonic skeletal muscles, resulting in myopathic facies and 'pseudodepression'. These conclusions establish that mother and son had the same monogenic autosomal dominant marfanoid disorder. A description of Nancy Hanks Lincoln as coarse-featured, and a little-known statement that a wasting disease contributed to her death at age 34, lends support to the multiple endocrine neoplasia type 2B hypothesis.

  20. Two-dimensional magnetotelluric inversion of the EMSLAB Lincoln Line

    1989-10-01

    Two-dimensional, Backus-Gilbert inversion of the EMSLAB land magnetotelluric (MT) data along the 200-km-long Lincoln Line has yielded optimally smooth geoelectric sections. Inversions were performed on the apparent resistivity and impedance phase data approximating the transverse magnetic (TM) mode. The land portion of the Lincoln Line traverses the edge of the North American plate that is being underthrust by the Juan de Fuca plate system. The inversion reveals three centralized conductive zones in the depth range of 20-40 km. A slightly conducting (<100 S) zone is centered at 30-35 km depth under the Oregon Coast Range; this feature may be the top of the subducting Juan de Fuca plate since there is complementary evidence here from Consortium for Continental Reflection Profiling seismic data. A prominent conduction zone of several hundred Siemens (S) is also detected at 30-35 km depth under the very resistive (>1000 ohm m) Western Cascades. Here the depth is too shallow for the zone to be the subducting plate. There is also evidence for a highly conducting (>1000 S) lower crust east of the High Cascades on the east end of the Lincoln Line. Two vertical conductive regions are also exposed in the inversion model. One occurs at 70-80 km from the coast under the Willamette Valley where a postulated Eocene trench may have left a suture zone. The second region is coincident with surface hydrothermal activity along the Western-High Cascades boundary. There are ample sources of water in the crust, e.g., in subducted sediments, from dehydration reactions along the upper plate boundary, and in volcanic arc magmas, to lead us to believe that hot, saline water is the major source of the conductive occurrences along the Lincoln Line. However, the various zones appear to be distinct, and the water may be trapped by different mechanisms.

    To date, no single diagnosis has unified the psychiatric illness and the numerous poorly defined physical complaints that Mary Lincoln (née Todd, 1818-1882) suffered in adulthood. Here, I show that her physical ailments spanned 30 years and included sore mouth, pallor, paresthesias, the Lhermitte symptom, fever, headaches, fatigue, resting tachycardia, edema, episodic weight loss, progressive weakness, ataxia, and visual impairment. Long thought hypochondriacal, these findings, plus their time course and her psychopathology (irritability, delusions, hallucinations, with preserved clarity), are all consistent with vitamin B12 deficiency. Pernicious anemia most probably caused this deficiency: she lacked risk factors for other causes, and her consanguineous parents both derived from a region of Scotland having a high incidence of pernicious anemia. A diagnosis of chronic multisystem pernicious anemia would clarify the conduct of Mary Lincoln as First Lady and widow, and illuminate challenges faced by her husband, President Abraham Lincoln. Her case highlights many forgotten features of the natural history of untreated pernicious anemia and is unique in the medical literature in demonstrating such a course extending over a lifetime.

    Maintaining elk (Cervus elaphus roosevelti) herds that frequent Lewis and Clark National Historical Park (NHP) is central to the park’s purpose of preserving the historic, cultural, scenic, and natural resources. Elk were critical to sustaining the members of the Lewis and Clark expedition by providing food and clothing over the winter of 1805-1806. Today, elk viewing opportunities in the park and surrounding region generate broad appeal with the visiting public, which number over 250,000 per year at the Fort Clatsop visitor center. This protocol describes procedures for monitoring trends in the use of the Fort Clatsop area by Roosevelt elk. Specific objectives of elk monitoring in Lewis and Clark NHP are to measure the relative use and proportion of area used by elk during winter in the Fort Clatsop Unit of the park, and the rate at which elk are sighted from roads in and around the park. Relative use and the proportion of area used by elk are determined from elk fecal pellet surveys conducted every other year in the Fort Clatsop park unit. Pairs of observers visit a systematic array of permanent plots in the fall to clear them of elk fecal pellets, and return to the plots in late winter to count elk fecal pellets that have accumulated during winter. Half of the subplots are counted by two independent observers, which allows for the estimation of relative use and proportion of area occupied by elk with analyses of detection biases that account for unseen elk pellet groups. Standardized road surveys are conducted in and near the Fort Clatsop park unit three or four times monthly during alternate months. Data from road surveys are used to quantify the rate that park visitors would be expected to see elk, when driving the selected set of routes. The monitoring protocol is based on three field seasons of development and testing. The protocol narrative describes the background, rationale, sampling design, field methods, analytical methods, data management, reporting

    Lincoln Composites operates a facility for designing, testing, and manufacturing composite pressure vessels. Lincoln Composites also has a U.S. Department of Energy (DOE)-funded project to develop composite tanks for high-pressure hydrogen storage. The initial stage of this project involves testing the permeation of high-pressure hydrogen through polymer liners. The company recently moved and is constructing a dedicated research/testing laboratory at their new location. In the meantime, permeation tests are being performed in a corner of a large manufacturing facility. The safety review team visited the Lincoln Composites site on May 25, 2010. The project team presented an overview of the company and project and took the safety review team on a tour of the facility. The safety review team saw the entire process of winding a carbon fiber/resin tank on a liner, installing the boss and valves, and curing and painting the tank. The review team also saw the new laboratory that is being built for the DOE project and the temporary arrangement for the hydrogen permeation tests.

    Water samples were collected from 76 wells throughout Clark County, in southwest Washington, during April and May 1988, and were analyzed from concentrations of major ions, silica, nitrate, phosphorus, aluminum, manganese, radon, and bacteria. Samples from 20 wells were analyzed for concentrations of trace elements and organic compounds, including most of those on the US Environmental Protection Agency (USEPA) priority pollutant list. Dissolved solids concentrations range from 12 to 245 mg/L, with a median concentration of 132 mg/L. The major dissolved constituents are calcium, bicarbonate, and silica, and, in some samples, sodium. Nitrate concentrations exceeded 1.0 mg/L throughout the Vancouver urban area, and were as large as 6.7 mg/L. Comparison with limited historical data indicates that nitrate concentrations were somewhat correlated, possibly indicating similar sources. Volatile organic compound, including tetrachloroethane and 1,1,1-trichloroethane, were detected in samples from three wells in the Vancouver area. Trace amounts of volatile organic compounds were reported in samples from several other wells, but at concentrations too close to analytical detection limits to ascertain that they were in the groundwater. Trace elements and radiochemical constituents were present at small levels indicating natural sources for these constituents. Only pH, turbidity, iron, manganese, and total coliform bacteria had values that did not meet USEPA Drinking Water Standards.

  7. Initial Geomorphic Responses to Removal of Milltown Dam, Clark Fork River, Montana, USA

    The removal of Milltown Dam on the Clark Fork River, Montana, USA, is creating a field-scale experiment on upstream and downstream responses to dam removal and on how gravel-bed rivers respond to sediment pulses. Milltown Dam was removed in 2008, reconnecting the Clark Fork River to its upstream basin in terms of sediment transport and fish passage. This dam removal is especially notable because (1) it is the largest dam removal to date in the United States in terms of the volume of reservoir sediment potentially available for downstream transport (over 3 million m3; 1.7 million m3 are being mechanically removed); and (2) the dam is the downstream end of the largest Superfund site in the United States, the Clark Fork Complex, and reservoir sediments are composed largely of contaminated mine tailings. Data collection on pre- and post-dam removal channel morphology, bed sediment characteristics, and sediment loads are being used to investigate spatial and temporal patterns of sediment transport and deposition associated with this dam removal. In the first several months following breaching of the dam, snowmelt runoff with a 3-year recurrence interval peak caused substantial erosion and downstream transport of metals-laden sediments from Milltown reservoir. Reservoir sediments in the Clark Fork arm of Milltown reservoir eroded at levels far exceeding modeling predictions as a result of both incision to the new base level created by dam removal and bank retreat of over 200 m in reaches upstream of a constructed bypass reach and remediation area. Copper and other metals in these eroded reservoir sediments provide a tracer for identifying whether sediment deposits observed downstream of the dam originated from Milltown reservoir or uncontaminated tributaries and indicate that Milltown sediments have reached over 200 km downstream. Downstream deposition has been greatest along channel margins and in side-channel areas, whereas the transport capacity of the active channel

    Ogle, K.M.; Eddy-Miller, C. A.; Busing, C.J.

    1996-01-01

    Total water use in Lincoln County, Wyoming in 1993 was estimated to be 405,000 Mgal (million gallons). Water use estimates were divided into nine categories: public supply, self-supplied domestic, commercial, irrigation, livestock, indus ial, mining, thermoelectric power, and hydro- electric power. Public supply water use, estimated to be 2,160 Mgal, primarily was obtained from springs and wells. Shallow ground water wells were the primary source of self-supplied domestic water, estimate to be 1.7 Mgal, and 53 percent of those wells were drilled to a depth of 100 feet or less. Commercial water use, estimated to be 117 Mgal, was obtained from public-supply systems. Surface water supplied an estimated 153,000 Mgal of the total estimated water use of 158,000 Mgal for irrigation in 1993. Sprinkler and flood irrigation technology were used about equally in the northern part of Lincoln County and flood irrigation was the primary technology used in the southern part. Livestock, industrial, and mining were not major water users in Lincoln County in 1993. Livestock water use totaled an estimated 203 Mgal. Industrial water use was estimated to be 120 Mgal from self-supplied water sources and 27 Mgal from public supplied water source Mining water use was an estimated 153 Mgal. Thermoelectric and hydroelectric power generation used surface water sources. Thermoelectric power water use was an estimated 5,900 Mgal. An estimated 238,000 Mgal of water was used to generate hydroelectc power at Fontenelle Reservoir on the Green River.

    Premature closure of one coronal skull suture produces a characteristic arching or relative elevation of the superior orbital rim on the involved side. This sign is associated with facial asymmetry, and both signs are usually the most conspicuous features in patients with mild unilateral coronal craniosynostosis. Photographs suggest that at least 9 individuals over 5 generations of the Abraham Lincoln family had premature closure of 1 coronal suture. In 8 males, there was involvement of the left side; in 1 female, there was involvement of the right side. PMID:20856045

  3. Geothermal Heat Pumps in K-12 Schools -- A Case Study of the Lincoln, Nebraska, Schools

    SciTech Connect

    Shonder, J.A.

    2000-05-02

    Geothermal heat pumps (GHPs) have been shown to have a number of benefits over other technologies used to heat and cool buildings and provide hot water, combining high levels of occupant comfort with low operating and maintenance costs. Public facilities represent an increasingly important market for GHPs, and schools are a particularly good application, given the large land area that normally surrounds them. Nevertheless, some barriers remain to the increased use of GHPs in institutional and commercial applications. First, because GHPs are perceived as having higher installation costs than other space conditioning technologies, they are sometimes not considered as an option in feasibility studies. When they are considered, it can be difficult to compile the information required to compare them with other technologies. For example, a life cycle cost analysis requires estimates of installation costs and annually recurring energy and maintenance costs. But most cost estimators are unfamiliar with GHP technology, and no published GHP construction cost estimating guide is available. For this reason, estimates of installed costs tend to be very conservative, furthering the perception that GHPs are more costly than other technologies. Because GHP systems are not widely represented in the various softwares used by engineers to predict building energy use, it is also difficult to estimate the annual energy use of a building having GHP systems. Very little published data is available on expected maintenance costs either. Because of this lack of information, developing an accurate estimate of the life cycle cost of a GHP system requires experience and expertise that are not available in all institutions or in all areas of the country. In 1998, Oak Ridge National Laboratory (ORNL) entered into an agreement with the Lincoln, Nebraska, Public School District and Lincoln Electric Service, the local electric utility in the Lincoln area, to study four new, identical elementary

    1995-12-31

    The Regional Ecorisk Field Investigation was conducted at the Clark Fork River Superfund Site (Montana) to evaluate the relationships between plant communities and tailings deposits in riparian habitats and to evaluate food-chain transfer of trace elements to selected wildlife species. Stations were selected to represent a range of vegetation biomass (or cover) values and apparent impact of trace elements, with some areas of lush vegetation, some areas of mostly unvegetated soil (e.g., < 30 percent plant cover), and a gradient in between. For the evaluation of risk to wildlife, bioaccumulation of metals was evaluated in native or naturalized plants, terrestrial invertebrates, and the deer mouse (Peromyscus maniculatus). Potential reproductive effects in the deer mouse were evaluated by direct measurements. For other wildlife species, bioaccumulation data were interpreted in the context of food web exposure models. Total biomass and species richness of riparian plant communities are related to tailings content of soil as indicated by pH and metals concentrations. Risk to populations of omnivorous small mammals such as the deer mouse was not significant. Relative abundance and reproductive condition of the deer mouse were normal, even in areas of high metals enrichment. Based on exposure models and site-specific tissue residue data for dietary species, risk to local populations of predators such as red fox and American kestrel that feed on deer mice and terrestrial invertebrates is not significant. Risk to herbivores related to metals bioaccumulation in plant tissues is not significant. Population level effects in deer and other large wildlife are not expected because of the large home ranges of such species and compensatory demographic factors.

    Williams, Willie E.

    Lincoln University, under the Lincoln Advanced Science and Engineering Reinforcement (LASER) Program, has identified and successfully recruited over 100 students for majors in technical fields. To date, over 70 percent of these students have completed or will complete technical degrees in engineering, physics, chemistry, and computer science. Of those completing the undergraduate degree, over 40 percent have gone on to graduate and professional schools. This success is attributable to well planned approaches to student recruitment, training, personal motivation, retention, and program staff. Very closely coupled to the above factors is a focus designed to achieve excellence in program services and student performance. Future contributions by the LASER Program to the pool of technical minority graduates will have a significant impact. This is already evident from the success of the students that began the first year of the program. With program plans to refine many of the already successful techniques, follow-on activities are expected to make even greater contributions to the availability of technically trained minorities. For example, undergraduate research exposure, broadened summer, and co-op work experiences will be enhanced.

    The legacy of Charles Darwin and Abraham Lincoln is to champion the dignity inherent in every human being. The moment of the bicentennial of their births provides an opportunity to celebrate and reflect on ways they have shaped our understanding and commitment to human rights. The naturalist and the constitutional lawyer, so different in circumstance and discipline, were morally allied in the mission to eradicate slavery. The profound lessons to be extracted from the lives of these two icons bind us to the agonizing reality that nearly 150 years after Gettysburg and the publication of the Descent of Man, and Selection in Relation to Sex, there remains much work to do toward advancing the security, respect, and equality of our species. This article describes how Darwin and Lincoln's inspiring legacies guided the author's personal choices as a scientist and activist. The essay concludes with a set of questions and challenges that confront us, foremost among which is the need to balance actions in response to the violation of negative rights by actions in the pursuit of positive rights.

    2016-01-01

    In 1895, Percival Lowell hired eminent telescope maker Alvan G. Clark to build a 24-inch refractor. Lowell intended the telescope intitally for observing Mars in support of his controversial theories about life on that planet. Clark finished the telescope within a year and at a cost of $20,000. Lowell and his staff of assistants and astronomers began observing through it on July 23, 1896, setting off a long and productive career for the telescope.While Lowell's Mars studies dominated early work with the Clark, V.M. Slipher by the 1910s was using it to observe planetary rotations and atmospheric compositions. He soon revolutionized spectroscopic studies, gathering excruciatingly long spectra - some in excess of 40 hours - of the so-called white nebula and determining startling radial velocities, evidence of an expanding universe. In the 1960s, scientists and artists teamed up on the Clark and created detailed lunar maps in support of the Apollo program.In recent decades, the Clark has played a central role in the education programs at Lowell, with general public audiences, students, and private groups all taking advantage of this unique resource.With this nearly 120 years of contant use, the Clark had been wearing down in recent years. The telescope was becoming more difficult to move, old electrical wiring in the dome was a fire hazard, and many of the telescope's parts needed to be repaired or replaced.In 2013, Lowell Observatory began a fundraising campaign, collecting $291,000 to cover the cost of dome and telescope renovation. Workers removed the entire telescope mount and tube assembly from the dome, examining every part from tube sections to individuals screws. They also stabilized the dome, adding a water vapor barrier and new outer wall while reinforcing the upper dome. The project lasted from January, 2014 through August, 2015. The facility reopened for daytime tours in September, 2015 and evening viewing the following month.

    In 1988, the US Army Corps of Engineers and the City of Seattle placed material on the upper beach at Lincoln Park, in West Seattle, Washington. The fill served to mitigate shoreline erosion that had caused undercutting and collapse of the seawall in several places. A series of pre- and post-construction studies have been conducted to assess the impacts to marine biota of fill placement and movement of surface substrate. This study was designed to monitor infaunal bivalves and eelgrass from intertidal areas in and adjacent to the area of original fill placement. Findings from this survey were compared to previous survey results to determine (1) if recruitment of infaunal bivalves to the fill area has occurred, (2) if infaunal bivalve densities outside the fill area are stable, and (3) if eelgrass distribution and abundance have remained stable along the adjacent shoreline. To maximize comparability of findings from this survey with previous studies, sampling techniques, transects, and tidal elevations were consistent with previous studies at this site.

  17. Abraham Lincoln's blue pills. Did our 16th president suffer from mercury poisoning?

    2001-01-01

    It is well known that Abraham Lincoln took a medicine called "blue mass" or "blue pill," commonly prescribed in the 19th century. What is now hardly known is that the main ingredient of blue mass was finely dispersed elemental mercury. As his friends understood, mercury was often prescribed for melancholy or "hypochondriasis," a condition Lincoln famously endured. Mercury in the form of the blue pill is a potential neurotoxin, which we have demonstrated by recreating and testing the recipe. We present the testimony of many of Lincoln's contemporaries to suggest that Lincoln suffered the neurobehavioural consequences of mercury intoxication but, perhaps crucial to history, before the main years of his presidency; he was astute enough to recognize the effects and stop the medication soon after his inauguration.

    1986-01-01

    A hydrologic investigation to define areas of brine contamination in shallow freshwater aquifers commonly used for streams that drain the Brookhaven Oil Field, was conducted from October 1983 to September 1984. The Brookhaven Oil Field covers approximately 15 sq mi in northwestern Lincoln County, Mississippi. Since 1943, disposal of approximately 544.2 million barrels of brine pumped from the oil producing zone (lower part of the Tuscaloosa Formation) has contaminated the Citronelle aquifer, the Hattiesburg aquifers, and streams that drain the oil field. Approximately 5 sq mi of the shallow Citronelle aquifer contain water with chloride concentrations higher than normal for this area ( > 20 mg/L). Brine contamination has moved from the source laterally through the Citronelle aquifer to discharge into nearby streams and vertically into the underlying Hattiesburg aquifers. Contamination is most noticeable in Shaws Creek when streamflow originates primarily from groundwater inflow (approximately 87% of the time during the study). Additional study is required to define contaminant plumes, rates of groundwater movement and geohydrochemical reactions between the contaminant and aquifer materials. These data would allow accurate predictions of location, extent and degree of contamination in the study area. (Author 's abstract)

  2. Geologic Map of the Pahranagat Range 30' x 60' Quadrangle, Lincoln and Nye Counties, Nevada

    2007-01-01

    Introduction The Pahranagat Range 30' x 60' quadrangle lies within an arid, sparsely populated part of Lincoln and Nye Counties, southeastern Nevada. Much of the area is public land that includes the Desert National Wildlife Range, the Pahranagat National Wildlife Refuge, and the Nellis Air Force Base. The topography, typical of much of the Basin and Range Province, consists of north-south-trending ranges and intervening broad alluvial valleys. Elevations range from about 1,000 to 2,900 m. At the regional scale, the Pahranagat Range quadrangle lies within the Mesozoic and early Tertiary Sevier Fold-and-Thrust Belt and the Cenozoic Basin and Range Province. The quadrangle is underlain by a Proterozoic to Permian miogeoclinal section, a nonmarine clastic and volcanic section of middle Oligocene or older to late Miocene age, and alluvial deposits of late Cenozoic age. The structural features that are exposed reflect relatively shallow crustal deformation. Mesozoic deformation is dominated by thrust faults and asymmetric or open folds. Cenozoic deformation is dominated by faults that dip more than 45i and dominostyle tilted blocks. At least three major tectonic events have affected the area: Mesozoic (Sevier) folding and thrust faulting, pre-middle Oligocene extensional deformation, and late Cenozoic (mainly late Miocene to Holocene) extensional deformation. Continued tectonic activity is expressed in the Pahranagat Range area by seismicity and faults having scarps that cut alluvial deposits.

    Skin cancer is the most common form of cancer in the United States. Although melanoma accounts for just 11% of all types of skin cancer, it is responsible for most of the deaths, claiming more than 7910 lives annually. Melanoma is visually difficult for clinicians to differentiate from Clark nevus lesions which are benign. The application of pattern recognition techniques to these lesions may be useful as an educational tool for teaching physicians to differentiate lesions, as well as for contributing information about the essential optical characteristics that identify them. Purpose: This study sought to find the most effective features to extract from melanoma, melanoma in situ and Clark nevus lesions, and to find the most effective pattern-classification criteria and algorithms for differentiating those lesions, using the Computer Vision and Image Processing Tools (CVIPtools) software package. Methods: Due to changes in ambient lighting during the photographic process, color differences between images can occur. These differences were minimized by capturing dermoscopic images instead of photographic images. Differences in skin color between patients were minimized via image color normalization, by converting original color images to relative-color images. Relative-color images also helped minimize changes in color that occur due to changes in the photographic and digitization processes. Tumors in the relative-color images were segmented and morphologically filtered. Filtered, relative-color, tumor features were then extracted and various pattern-classification schemes were applied. Results: Experimentation resulted in four useful pattern classification methods, the best of which was an overall classification rate of 100% for melanoma and melanoma in situ (grouped) and 60% for Clark nevus. Conclusion: Melanoma and melanoma in situ have feature parameters and feature values that are similar enough to be considered one class of tumor that significantly differs from

    An improperly healed fracture was the most common reason for the medical malpractice crisis between the 1830s and 1860s in the United States. As a practicing lawyer in Illinois, Abraham Lincoln defended physicians in medical malpractice law suits. One of these was Dr. Powers Ritchey, who was sued for malpractice in 1855. Lincoln agreed to represent Dr. Ritchey in 1858 as the case was appealed to the supreme court of Illinois. In the interim, Lincoln defended two indicted murderers and won acquittals for both. Between the two murder trials, Lincoln debated Stephen A. Douglas while running for U.S. Senator from Illinois. Lincoln believed that Ritchey's case was poorly represented in the lower court. Ritchey's prior attorneys did not file a bill of exceptions to the testimony of the plaintiff's expert medical witnesses. Lincoln attempted to rebut the allegation of a lack of reasonable medical care and diligence by Ritchey, and he sought to secure a new trial for his client. In its decision, the supreme court of Illinois did not find any error and affirmed the lower court's judgment. PMID:14768936

    A seismic refraction line crossing the Lincoln Sea was acquired in 2006. It proves the existence of a deep sedimentary basin underlying the Lincoln Sea. This basin appears to be comparable in width and depth to the Sverdrup Basin of the Canadian Arctic Islands. The stratigraphy of the Lincoln Sea Basin is modelled in analogy to the Sverdrup Basin and the Central Spitsbergen Basin, two basins between which the Lincoln Sea intervened before the onset of seafloor spreading in the Eurasian Basin. The refraction data indicates that the Lincoln Sea Basin is capped by a kilometre-thick, low-velocity layer, which is taken to indicate an uplift history similar to, or even more favourable than, the fairway part of the Sverdrup Basin. Tectonic activity in the Palaeogene is likely to constitute the major basin scale risk. We conclude that the Lincoln Sea Basin is likely to be petroliferous and contains risked resources on the order of 1 ?? 109 barrels of oil, to which comes an equivalent amount of (associated and nonassociated) gas. ?? 2011 The Geological Society of London.

    NASA Astrophysics Data System (ADS)

    Green, Robert O.; Vane, Gregg

    The Clark Mountains in eastern California form a rugged, highly dissected area nearly 5000 ft above sea level, with Clark Mountain rising to 8000 ft. The rocks of the Clark Mountains and the Mescal Range just to the south are Paleozoic carbonate and clastic rocks, and Mesozoic clastic and volcanic rocks standing in pronounced relief above the fractured Precambrian gneisses to the east. The Permian Kaibab Limestone and the Triassic Moenkopi and Chinle Formations are exposed in the Mescal Range, which is the only place in California where these rocks, which are typical of the Colorado Plateau, are found. To the west, the mountains are bordered by the broad alluvial plains of Shadow Valley. Cima Dome, which is an erosional remnant carved on a batholithic intrusion of quartz monzonite, is found at the south end of the valley. To the east of the Clark and Mescal Mountains is found the Ivanpah Valley, in the center of which is located the Ivanpah Play. Studies of the Clark Mountains with the airborne visible/infrared imaging spectrometer are briefly described.

    The health of forests worldwide has become of greater interest to the scientific community in the last decades. Catastrophic events such as wild fires, insect infestations, and diseases all point to a less than ideal state in these areas. In the last fifteen years the Forest Health Protection office of the Forest Service identified and has been monitoring the distribution and effects of white pine blister rust (Cronartium ribicola) in the white pine community in the stands of the Lincoln National Forest. The Lincoln National Forest covers an area of approximately 1,196,419 acres in parts of four counties in southeastern New Mexico. It consists of three ranger districts: Sacramento, Smokey Bear and Guadalupe. The Lincoln National Forest attracts visitors because of its natural beauty and recreational areas. It is also home to several endangered and threatened species such as the Mexican Spotted Owl., the Sacramento Prickly Poppy, and the Sacramento Mountain Thistle. Loss of white pine stands is detrimental not only from a human perspective but would also result in loss of natural habitats for already rare species. According to Conklin (1994) there are nearly 500,000 acres of forests in the Sacramento Mountains, the adjoining White Mountains and the nearby Capitan Mountains that contain southwestern white pine. Starting in 1990 Conklin established several infected plots within this area and monitors them on a 3-year rotation period. In an attempt to further analyze the effects of the disease, samples from the different localities were obtained and their spectral responses studied by using a GER spectroradiometer with data acquisition capabilities in the 350 to 2500 nm range. The interaction of an object with electromagnetic energy is unique for each target and is based on its physical characteristics. We are able to note spectral differences in areas other than the visible range which are not accessible to the human eye. Plants stressed by such factors as drought

  14. Colorado Yule Marble; building stone of the Lincoln Memorial

    USGS Publications Warehouse

    McGee, Elaine S.

    1999-01-01

    The Colorado Yule marble, quarried in Marble, Colo., is a very pure white marble, and it has been widely acclaimed for its quality and purity. This marble has been used for many prominent buildings; one of the most notable is the Lincoln Memorial in Washington, D.C., built nearly 80 years ago. Although most of the marble in the memorial appears to be in very good condition, some of the stones have developed pronounced surficial roughness and show a significant loss of carved details and rounded edges compared with adjacent stones. Because adjacent blocks of marble receive nearly identical exposure to weathering agents that cause deterioration of the marble, it seems very likely that this pronounced difference in durability of adjacent stones arises from some inherent characteristic of the marble. The Colorado Yule marble is a nearly pure calcite marble with minor inclusions of mica, quartz, and feldspar. Compositions of the calcite and the inclusion phases in the marble are typical for those phases. The calcite grains that compose the marble are irregularly shaped and range from 100 to 600 micrometers in diameter. The texture of the marble is even, with a slight preferred directional elongation that is visible when the marble is cut in certain directions. Physical tests of the marble show that its strength is comparable to that of other marbles typically used in buildings. Variations in the durability of the marble, like those seen at the Lincoln Memorial, are not related to variations in calcite composition or to the presence of inclusions in the marble. Most likely, the variations arise from differences in the calcite grain boundaries and the degree to which the grains interlock with one another. Weak grain boundaries that permit water or solutions to penetrate into the marble and dissolve the calcite grains at their edges cause the marble to disaggregate or ?sugar.? Subtle differences in texture that occur in the marble from various parts of the quarry probably

    The Shenandoah Stables (SS) site is located in a rural area near Moscow Mills, Lincoln County, Missouri, within the upper floodplain of Crooked Creek. The property includes an enclosed arena and horse stables building, a number of single family residences, a livestock operation, and other small businesses on approximately 5- to 10-acre land parcels around the facility. In 1971, the area inside the arena was sprayed with approximately 1,500 gallons of dioxin-contaminated waste oil for dust control purposes. Subsequently, a number of adverse effects were noted in horses, other animals, and in humans. The ROD addresses the final remedy for the site, the removal of 3,471 cubic yards of contaminated materials currently stored onsite in 2,660 separate containers. The primary contaminant of concern affecting the soil and debris is dioxin.

    Macroinvertebrate contaminated with metals in the Clark Fork River of Montana have been demonstrated to be a potentially toxic component in the diet of trout. Because sediment was the suspected source of metals to these invertebrates, bioaccumulation of As, Cd, Cu, Pb, and Zn from sediment was evaluated by exposing the amphipod Hyalella azteca for 28 d in the laboratory to samples of sediment collected from depositional areas of the Clark Fork River. Benthic invertebrates collected from riffles adjacent to the depositional areas were also analyzed for metals. The pattern of metal accumulation between laboratory-exposed and field-collected animals was similar; however, the concentrations of metals in laboratory-exposed amphipods were often 50 to 75% less than were the concentrations of metals in the field-collected invertebrates. These findings indicate that sediment is a significant source of metals to invertebrates in the Clark Fork River. Additional studies should be conducted to determine threshold concentrations for effects of dietary metals on fish. Long-term monitoring of the river should include sampling benthic invertebrates for metal accumulation.

    In 1982, the Clarke County Planning Commission created a Water Supply committee which led to the following county actions: adoption of a resource conservation overlay zone to protect the County Sanitation Authority's public spring; submission of the first Virginia application for federal sole-source aquifer designation; drafting of a proposed oil and gas exploration and extraction ordinance; and a contract with the USGS for a three-year groundwater resources study. In February 1987, the Clarke County Plan was published. Six implementation strategies were recommended, the majority of which have been adopted: (1) on-site wastewater treatment system management; (2) a sinkhole ordinance; (3) well standards; (4) underground storage tank requirements; (5) community education; and (6) a geographic information system. This plan emphasizes direct local government land use policies designed to mitigate risks of groundwater contamination. The plan used existing technical information to focus on prevention as the best strategy for natural resource protection.

    An early interest in the chemistry of organic compounds of sulfur led Clarke to demonstrate a thiazole moiety in the structure of vitamin B1 and to study the formation of thiazolidine carboxylic acid from the reaction of cysteine and formaldehyde. This reaction became important in connection with the determination of the chemical structure of penicillin. Moreover, he had a major administrative role in the USA-UK collaboration (1943-1946) to attempt the chemical synthesis of penicillin.

    The technical achievements of Lewis and Clark have been celebrated in fields ranging from cartography to zoology. As America commemorates the bicentennial of their historic journey across the continent, this paper shows that their meteorological data and personal weather-related observations also are worthy of celebration. While the primary goal of the mission, as described by then-President Jefferson to the Congress, was economic and strategic, both Jefferson and cocaptains Lewis and Clark showed an interest in and capacity for scientific understanding of the meteorology of the then-unknown West. The seasonal evolution and variability of temperatures recorded for the first time by Lewis and Clark on the High Plains can now be shown to be quite close to average, thanks to many decades of collection of modern data by the U.S. Cooperative Observer Network stations along their route. While the diets, lives, and experiences of these early explorers and their men were profoundly different from those of modern Americans, the climate that they documented for the first time with care and accuracy remains familiar to us today.

    This report inventories the surface distribution of silicic tuffs in Nye, Esmeralda, and Lincoln Counties, NV, based on a review of available literature. The inventory was taken to provide a data base in evaluating tuff sites for the disposal of high-level nuclear waste. Silicic ash-flow tuffs that are about 11 to 34 million years (my) old are widespread in these counties. These rocks are locally deformed by right-lateral movement along Walker Lane and the Las Vegas Shear Zone, and left-lateral movement along a zone from near the Nevada Test Site (NTS) to the Utah border, and are commonly offset by steeply dipping normal faults. The normal faults that bound horsts, grabens, and tilted-fault blocks of the Basin-and-Range Province began to form 30 my ago; some are still active. Tuff distribution is discussed on a regional basis. Tuff thicknesses and alterations, structural complexity, and proximity to recent faulting, recent volcanism, and mineral resources are discussed for each area. Although the literature on which it is based is often incomplete and sketchy, this report is intended to serve as a basis for future, more detailed work that includes initial field inspection, detailed field and laboratory studies, and extrapolations to the subsurface.

In the FEIS, DOE states that, 'information useful for an evaluation of land-use and ownership impacts should identify the current ownership of the land that its activities could disturb, and the present and anticipated future uses of the land' (emphasis added). As stated, any information that helps evaluate the land use and ownership impacts needs to look at the present and anticipated uses of the land.

    Oceanographic measurements taken between 1989 and 1994 in the Lincoln Sea describe the currents and water mass structure along the continental slope of the Arctic Basin between the Canadian and Eurasian Basins. The measurements included periodic conductivity and temperature versus depth (CTD) profiles from ice camps, CTD cross sections normal to the slope, and year-round current measurements. Analysis of this data describes the hydrographic structure of the waters over the continental slope and identifies some significant interannual variations. An undercurrent, confined to the continental slope, with a width of about 50 km and speeds of 5-9 cm s-1 is shown in geostrophic current cross sections. The presence of this easterly flow at depth is confirmed by current meter measurements, and its existence has also been observed in the Beaufort Sea and the Barents Sea [Aagaard, 1989]. The waters within this undercurrent exhibit temperature-salinity (TS) characteristics similar to Canadian Basin waters, suggesting a boundary current system which is continuous along the continental slope north of Alaska and Canada. Significant interannual variations in temperature and salinity profiles may be related to variations in the large-scale circulation of the Arctic. Examination of the upper pycnocline waters over the slope between 1991 and 1994 indicated a relative temperature maximum overlying a minimum, TS characteristics similar to waters attributed to Bering Sea origin found in the Canadian Basin. These characteristics were not seen, however, during 1989 and 1990, suggesting a recent increase in the transport of surface waters from the Canadian Basin into the Eurasian Basin.

    2007-01-01

    Massachusetts Institute of Technology, Lincoln Laboratory (MIT LL) has been developing both continuous and burst solid-state focal-plane-array technology for a variety of high-speed imaging applications. For continuous imaging, a 128 × 128-pixel charge coupled device (CCD) has been fabricated with multiple output ports for operating rates greater than 10,000 frames per second with readout noise of less than 10 e- rms. An electronic shutter has been integrated into the pixels of the back-illuminated (BI) CCD imagers that give snapshot exposure times of less than 10 ns. For burst imaging, a 5 cm × 5 cm, 512 × 512-element, multi-frame CCD imager that collects four sequential image frames at megahertz rates has been developed for the Los Alamos National Laboratory Dual Axis Radiographic Hydrodynamic Test (DARHT) facility. To operate at fast frame rates with high sensitivity, the imager uses the same electronic shutter technology as the continuously framing 128 × 128 CCD imager. The design concept and test results are described for the burst-frame-rate imager. Also discussed is an evolving solid-state imager technology that has interesting characteristics for creating large-format x-ray detectors with ultra-short exposure times (100 to 300 ps). The detector will consist of CMOS readouts for high speed sampling (tens of picoseconds transistor switching times) that are bump bonded to deep-depletion silicon photodiodes. A 64 × 64-pixel CMOS test chip has been designed, fabricated and characterized to investigate the feasibility of making large-format detectors with short, simultaneous exposure times.

  10. The role of Abraham Lincoln in securing a charter for a homeopathic medical college.

    PubMed

    Spiegel, Allen D; Kavaler, Florence

    2002-10-01

    In 1854, Abraham Lincoln was retained to prepare a state legislative proposal to charter a homeopathic medical college in Chicago. This was a complex task in view of the deep-seated animosity between allopathic or orthodox medical practitioners and irregular healers. Homeopathy was regarded as a cult by the nascent American Medical Association. In addition, the poor reputation of medical education in the United States in general, further complicated the project. Lincoln and influential individuals in Illinois lobbied legislators and succeeded in securing the charter. Subsequently, the Hahnemann Homeopathic Medical College accepted its first class in 1860 and with its successors remained in existence for almost sixty-five years. PMID:12238734

    1995-05-01

    Optical lithography at a 193-nm exposure wavelength has been under development at MIT Lincoln Laboratory for several years, supported by ARPA's Advanced Lithography Program. As part of this program, a prototype 193-nm full-field step-and-scan lithographic exposure system was built and installed in the clean-room facilities of MIT Lincoln Laboratory. This exposure system has now been in use for one year, supporting a program of photoresist and lithographic process development at 193 nm. This paper describes the characteristics of the exposure system and some of the advances in 193-nm lithography that have been achieved with the system.

    Over the course of nearly three decades, a series of state of the art low frequency radio telescopes were developed in the dry lake bed of Clark Lake east of San Diego by Professor Bill Erickson and his colleagues and students. These instruments helped open the first window on the very poorly explored region of the electromagnetic spectrum below 100 MHz. Institutions involved with the construction and operation of the instruments included Convair (now General Dynamics), the University of Maryland, the University of California at San Diego, the University of Iowa, and the Goddard Space Flight Center.

  13. Song Competition Affects Monoamine Levels in Sensory and Motor Forebrain Regions of Male Lincoln's Sparrows (Melospiza lincolnii)

    PubMed Central

    Sewall, Kendra B.; Caro, Samuel P.; Sockman, Keith W.

    2013-01-01

    Male animals often change their behavior in response to the level of competition for mates. Male Lincoln's sparrows (Melospiza lincolnii) modulate their competitive singing over the period of a week as a function of the level of challenge associated with competitors' songs. Differences in song challenge and associated shifts in competitive state should be accompanied by neural changes, potentially in regions that regulate perception and song production. The monoamines mediate neural plasticity in response to environmental cues to achieve shifts in behavioral state. Therefore, using high pressure liquid chromatography with electrochemical detection, we compared levels of monoamines and their metabolites from male Lincoln's sparrows exposed to songs categorized as more or less challenging. We compared levels of norepinephrine and its principal metabolite in two perceptual regions of the auditory telencephalon, the caudomedial nidopallium and the caudomedial mesopallium (CMM), because this chemical is implicated in modulating auditory sensitivity to song. We also measured the levels of dopamine and its principal metabolite in two song control nuclei, area X and the robust nucleus of the arcopallium (RA), because dopamine is implicated in regulating song output. We measured the levels of serotonin and its principal metabolite in all four brain regions because this monoamine is implicated in perception and behavioral output and is found throughout the avian forebrain. After controlling for recent singing, we found that males exposed to more challenging song had higher levels of norepinephrine metabolite in the CMM and lower levels of serotonin in the RA. Collectively, these findings are consistent with norepinephrine in perceptual brain regions and serotonin in song control regions contributing to neuroplasticity that underlies socially-induced changes in behavioral state.

  14. Superior abstract-concept learning by Clark's nutcrackers (Nucifraga columbiana)

    Magnotti, John F.; Katz, Jeffrey S.; Wright, Anthony A.; Kelly, Debbie M.

    2015-01-01

    The ability to learn abstract relational concepts is fundamental to higher level cognition. In contrast to item-specific concepts (e.g. pictures containing trees versus pictures containing cars), abstract relational concepts are not bound to particular stimulus features, but instead involve the relationship between stimuli and therefore may be extrapolated to novel stimuli. Previous research investigating the same/different abstract concept has suggested that primates might be specially adapted to extract relations among items and would require fewer exemplars of a rule to learn an abstract concept than non-primate species. We assessed abstract-concept learning in an avian species, Clark's nutcracker (Nucifraga columbiana), using a small number of exemplars (eight pairs of the same rule, and 56 pairs of the different rule) identical to that previously used to compare rhesus monkeys, capuchin monkeys and pigeons. Nutcrackers as a group (N = 9) showed more novel stimulus transfer than any previous species tested with this small number of exemplars. Two nutcrackers showed full concept learning and four more showed transfer considerably above chance performance, indicating partial concept learning. These results show that the Clark's nutcracker, a corvid species well known for its amazing feats of spatial memory, learns the same/different abstract concept better than any non-human species (including non-human primates) yet tested on this same task.

  15. Unusual pre-Mount Simon geology in Clark County, Ohio

    1994-04-01

    A well drilled by Pure Oil Company in 1926 in Clark County, Ohio and seismic sections gathered by Wright State University in 1992 and 1993 in the proximity of that well identify unusual geology below the Mount Simon Sandstone. The pair of perpendicular seismic lines cross about a mile from the well. The well encountered about 365 m of a black phosphatic limestone below the Mount Simon Formation. This is the only well that has encountered this unit in Ohio. On each seismic section the pre-Mount Simon surface is irregular with as much as 100 m of relief. Below this surface about 2,000 m of layered rocks, that include the limestone at the top, show onlap to the north suggesting the filling of a basin. The units beneath this sequence of rocks are reverse faulted and dip to the west. When the Clark County seismic sections are compared to recent seismic data to the south in Clinton and Greene Counties similar features are observed. The authors believe the following sequence of events occurred. There was substantial faulting in the late Proterozoic to produce the westward dips and the irregular surface on which the overlying sequence of layered rocks was deposited. Then prior to deposition of the Mount Simon Sandstone, subareal erosion occurred producing a karst surface with at least 100 m relief.

  7. Spatial Patterns of Mercury Bioaccumulation in the Upper Clark Fork River Basin, MT

    NASA Astrophysics Data System (ADS)

    Staats, M. F.; Langner, H.; Moore, J. N.

    2010-12-01

    The Upper Clark Fork River Basin (UCFRB) in Montana has a legacy of historic gold/silver mine waste that contributes large quantities of mercury into the watershed. Mercury bioaccumulation at higher levels of the aquatic food chain, such as the mercury concentration in the blood of pre-fledge osprey, exhibit an irregular spatial signature based on the location of the nests throughout the river basin. Here we identify regions with a high concentration of bioavailable mercury and the major factors that allow the mercury to bioaccumulate within trophic levels. This identification is based on the abundance of mercury sources and the potential for mercury methylation. To address the source term, we did a survey of total mercury in fine sediments along selected UCFRB reaches, along with the assessment of environmental river conditions (percentage of backwaters/wetlands, water temperature and pH, etc). In addition, we analyzed the mercury levels of a representative number of macroinvertebrates and fish from key locations. The concentration of total mercury in sediment, which varies from reach to reach (tributaries of the Clark Fork River, <0.05 mg/kg to the main stem of the river, >5mg/kg) affects the concentration of mercury found at various trophic levels. However, reaches with a low supply of mine waste-derived mercury can also yield substantial concentrations of mercury in the biota, due to highly favorable conditions for mercury methylation. We identify that the major environmental factor that affects the methylation potential in the UCFRB is the proximity and connectivity of wetland areas to the river.

  8. Whitebark Pine Stand Condition, Tree Abundance, and Cone Production as Predictors of Visitation by Clark's Nutcracker

    PubMed Central

    Barringer, Lauren E.; Tomback, Diana F.; Wunder, Michael B.; McKinney, Shawn T.

    2012-01-01

    Background Accurately quantifying key interactions between species is important for developing effective recovery strategies for threatened and endangered species. Whitebark pine (Pinus albicaulis), a candidate species for listing under the Endangered Species Act, depends on Clark's nutcracker (Nucifraga columbiana) for seed dispersal. As whitebark pine succumbs to exotic disease and mountain pine beetles (Dendroctonus ponderosae), cone production declines, and nutcrackers visit stands less frequently, reducing the probability of seed dispersal. Methodology/Principal Findings We quantified whitebark pine forest structure, health metrics, and the frequency of nutcracker occurrence in national parks within the Northern and Central Rocky Mountains in 2008 and 2009. Forest health characteristics varied between the two regions, with the northern region in overall poorer health. Using these data, we show that a previously published model consistently under-predicts the proportion of survey hours resulting in nutcracker observations at all cone density levels. We present a new statistical model of the relationship between whitebark pine cone production and the probability of Clark's nutcracker occurrence based on combining data from this study and the previous study. Conclusions/Significance Our model clarified earlier findings and suggested a lower cone production threshold value for predicting likely visitation by nutcrackers: Although nutcrackers do visit whitebark pine stands with few cones, the probability of visitation increases with increased cone production. We use information theoretics to show that beta regression is a more appropriate statistical framework for modeling the relationship between cone density and proportion of survey time resulting in nutcracker observations. We illustrate how resource managers may apply this model in the process of prioritizing areas for whitebark pine restoration. PMID:22662186

  11. A New Wideband, Fully Steerable, Decametric Array at Clark Lake

    NASA Technical Reports Server (NTRS)

    Erickson, W. C.; Fisher, J. R.

    1974-01-01

    A fully steerable, decametric array for radio astronomy is under construction at the Clark Lake Radio Observatory near Borrego Springs, California. This array will be a T of 720 conical spiral antennas (teepee-shaped antennas, hence the array is called the TPT), 3.0 km by 1.8 km capable of operating between 15 and 125 MHz. Both its operating frequency and beam position will be adjustable in less than one millisecond, and the TPT will provide a 49-element picture around the central beam position for extended source observations. Considerable experience was gained in the operation of completed portions of the array, and successful operation of the final array is assured. The results are described of the tests which were conducted with the conical spirals, and the planned electronics and data processing systems are described.

    The Lewis and Clark expedition crossed the Continental Divide in 1805 on the way west to the Pacific Ocean. Based on journal entries, members of the expedition probably encountered two species of resident salmonids and four of the six species of anadromous salmonids and steelhead (Family Salmonidae, genus Oncorhynchus). The salmonid species were called common salmon (now known as Chinook salmon O. tshawytscha), red char (sockeye salmon O.nerka) white salmon trout (coho salmon [also known as silver salmon] O. kisutch), salmon trout (steelhead O. mykiss), and spotted trout (cutthroat trout O. clarkii). There was no evidence of the expedition encountering pink salmon O. gorbuscha, chum salmon O. keta, or species of true char Salvelinus spp. Common fishes procured from Indian tribes living along the lower Columbia River included eulachon Thaleichthys pacificus and white sturgeon Acipenser transmontanus. The identity of three additional resident freshwater species is questionable. Available descriptions suggest that what they called mullet were largescale sucker Catastomus macrocheilus, and that chubb were peamouth Mylocheilus caurinus. The third questionable fish, which they called bottlenose, was probably mountain whitefish Prosopium williamsoni, although there is no evidence that the species was observed in the Columbia River drainage. Missing from the species list were more than 20 other fishes known to Sahaptin-speaking people from the mid-Columbia region. More complete documentation of the icthyofauna of the Pacific Northwest region did not occur until the latter half of the 19th century. However, journals from the Lewis and Clark expedition provide the first documentation of Columbia River fishes.

    1999-06-19

    The Lincoln Public School District, in Lincoln, Nebraska, recently installed vertical-bore geothermal heat pump systems in four, new, elementary schools. Because the district has consistent maintenance records and procedures, it was possible to study repair, service and corrective maintenance requests for 20 schools in the district. Each school studied provides cooling to over 70% of its total floor area and uses one of the following heating and cooling systems: vertical-bore geothermal heat pumps (GHPs), air-cooled chiller with gas-fired hot water boiler (ACUGHWB), water-cooled chiller with gas-fired hot water boiler (WCCYGHWB), or water-cooled chiller with gas-fired steam boiler (WCUGSB). Preventative maintenance and capital renewal activities were not included in the available database. GHP schools reported average total costs at 2.13 cents/ft{sup 2}-yr, followed by ACC/GHWB schools at 2.88 cents/ft{sup 2}-yr, WCC/GSB schools at 3.73 cents/ft{sup 2}-yr, and WCC/GHWB schools at 6.07 cents/ft{sup 2}-yr. Because of tax-exemptions on material purchases, a reliance on in-house labor, and the absence of preventative maintenance records in the database, these costs are lower than those reported in previous studies. A strong relationship (R{sup 2}=O.52) was found between costs examined and cooling system age: the newer the cooling equipment, the less it costs to maintain.

  15. Abraham Lincoln's suit against a medical imposter who assaulted his client.

    In 1851, A. Lincoln, Esquire represented Edward Jones who charged in a law suit that his attending physician had assaulted him. Jones, also a lawyer, had sharply questioned Dr. Joseph S. Maus about his claims of attendance and graduation from Philadelphia's Jefferson Medical College, an allopathic medical school. Jones claimed that Maus became enraged at his persistent questioning and attacked him. In turn, Maus denied the allegation. He said that he was merely defending himself from Jones' blows with a large cane. Lincoln's legal approach was to argue about the state of medical education and whether Maus had really graduated from Jefferson Medical College. Acting as a peacemaker, he finally arranged to settle the dispute between Jones and Maus out of court. PMID:11554501

    The principal objective of this project was to develop insight into the scope of migration of working age Nevadans out of their county of birth; including the collection of data on their skill levels, desire to out or in-migrate, interactions between families of migratory persons, and the impact that the proposed high-level nuclear waste repository at Yucca mountain might have on their individual, and collective, decisions to migrate and return. The initial phase of this project reported here was conducted in 1992 and 1993 in Lincoln County, Nevada, one of the counties designated as ``affected`` by the proposed repository program. The findings suggest that a serious out-migration problem exists in Lincoln County, and that the Yucca mountain project will likely affect decisions relating to migration patterns in the future.

    A ground-water flow model was used in conjunction with a particle-tracking program to demonstrate a method of evaluating ground-water vulnerability. The study area encompassed the part of the Portland Basin located in Clark County, Washington. A new computer program was developed that interfaces the particle-tracking program with a geographic information system (GIS). The GIS was used to display and analyze the particle-tracking results and to evaluate ground-water vulnerability by identifying recharge areas and their characteristics, determining the downgradient impact of land use at recharge areas, and estimating the age of ground water. The report presents a description of the methods used and the results of the evaluation of ground-water vulnerability.

  1. 26 km of offset on the Lake Clark fault since late Eocene time

    USGS Publications Warehouse

    Haeussler, Peter J.; Saltus, Richard W.

    2005-01-01

    Aeromagnetic data over the Lake Clark Fault reveal a north-trending band of magnetic anomalies that are right-laterally offset about 26 km across the fault. The magnetic anomalies correlate spatially with a belt of dated 34-39-Ma granitic plutons. Thus, the Lake Clark Fault has had ~26 km of right-lateral offset in the past 34-39 Ma. The Castle Mountain Fault, which lies along the strike of the Lake Clark Fault to the east-northeast, must have had a similar or, possibly, greater amount of offset. We infer the presence of an additional right-lateral strike-slip fault about 35 km northwest of the Lake Clark Fault, herein named the 'Telequana Fault,' on the basis of 11 km of right-lateral offset of a north-trending band of magnetic anomalies.

  2. Early miocene bimodal volcanism, Northern Wilson Creek Range, Lincoln County, Nevada

    1996-01-01

    Early Miocene volcanism in the northern Wilson Creek Range, Lincoln County, Nevada, produced an interfingered sequence of high-silica rhyolite (greater than 74% SiO2) ash-flow tuffs, lava flows and dikes, and mafic lava flows. Three new potassium-argon ages range from 23.9 ?? 1.0 Ma to 22.6 ?? 1.2 Ma. The rocks are similar in composition, stratigraphic character, and age to the Blawn Formation, which is found in ranges to the east and southeast in Utah, and, therefore, are herein established as a western extension of the Blawn Formation. Miocene volcanism in the northern Wilson Creek Range began with the eruption of two geochemically similar, weakly evolved ash-flow tuff cooling units. The lower unit consists of crystal-poor, loosely welded, lapilli ash-flow tuffs, herein called the tuff member of Atlanta Summit. The upper unit consists of homogeneous, crystal-rich, moderately to densely welded ash-flow tuffs, herein called the tuff member of Rosencrans Peak. This unit is as much as 300 m thick and has a minimum eruptive volume of 6.5 km3, which is unusually voluminous for tuffs in the Blawn Formation. Thick, conspicuously flow-layered rhyolite lava flows were erupted penecontemporaneously with the tuffs. The rhyolite lava flows have a range of incompatible trace element concentrations, and some of them show an unusual mixing of aphyric and porphyritic magma. Small volumes of alkaline, vesicular, mafic flows containing 50 weight percent SiO2 and 2.3 weight percent K2O were extruded near the end of the rhyolite volcanic activity. The Blawn Formation records a shift in eruptive style and magmatic composition in the northern Wilson Creek Range. The Blawn was preceded by voluminous Oligocene eruptions of dominantly calc-alkaline orogenic magmas. The Blawn and younger volcanic rocks in the area are low-volume, bimodal suites of high-silica rhyolite tuffs and lava flows and mafic lava flows.

  3. The USNO 26'' Clark Refractor; From Visual Observations to Speckle Interferometry

    NASA Astrophysics Data System (ADS)

    Bartlett, Jennifer L.; Mason, B. D.; Hartkopf, W. I.

    2011-01-01

    Before addressing queries about how and what to preserve among astronomical devices, the question of what constitutes a historic instrument must be considered. Certainly, the lenses are the defining feature of a Clark refractor. Since 1867, when Newcomb inquired about the possibility of obtaining a great glass from Alvan Clark & Sons, the U.S. Naval Observatory 26-in (66-cm) equatorial has evolved in response to improvements in technology and changes in its observing program. After two major overhauls, only the objective remains of the equipment originally installed by the Clarks in 1873 at the old Observatory site in Foggy Bottom. However, the telescope retains its reputation as a historic Clark refractor. The USNO telescope was briefly renowned as the largest refractor in the world; the second of five such achievements by the Clarks. Through it, Hall first detected the moons of Mars in 1877. However, by that time, the Clarks had already refigured the flint glass. Hall and Gardiner had also altered the drive mechanism. When the USNO moved to its present Georgetown Heights location in 1893, the great equatorial was refurbished with its original Clark optics installed on a more robust Warner & Swasey mount. Peters eventually incorporated discarded parts from the original mounting into his photographic telescopes during the first half of the 20th century. The 26'' refractor underwent further modernization in the early 1960s to facilitate the xy-slide of a Hertzsprung-style photographic double star camera. In 1965, the objective was disassembled for cleaning and reassembled with new spacers. The most recent maintenance included re-wiring and replacing several motors and the hand paddles. Originally designed as a visual instrument, the USNO 26'' Clark refractor now hosts a speckle interferometer for its current double star program. Despite continuing modifications, this telescope remains a fine example of the optician's art.

    Same/Different abstract-concept learning by Clark's nutcrackers (Nucifraga columbiana) was tested with novel stimuli following learning of training set expansion (8, 16, 32, 64, 128, 256, 512, and 1024 picture items). The resulting set-size function was compared to those from rhesus monkeys (Macaca mulatta), capuchin monkeys (Cebus apella), and pigeons (Columba livia). Nutcrackers showed partial concept learning following initial eight-item set learning, unlike the other species (Magnotti, Katz, Wright, & Kelly, 2015). The mean function for the nutcrackers' novel-stimulus transfer increased linearly as a function of the logarithm of training set size, which intersected its baseline function at the 128-item set size. Thus, nutcrackers on average achieved full concept learning (i.e., transfer statistically equivalent to baseline performance) somewhere between set sizes of 64 to 128 items, similar to full concept learning by monkeys. Pigeons required a somewhat larger training set (256 items) for full concept learning, but results from other experiments (initial training and transfer with 32- and 64-item set sizes) suggested carryover effects with smaller set sizes may have artificially prolonged the pigeon's full concept learning. We find it remarkable that these diverse species with very different neural architectures can fully learn this same/different abstract concept, and (at least under some conditions) do so with roughly similar sets sizes (64-128 items) and numbers of training exemplars, despite initial concept learning advantages (nutcrackers), learning disadvantages (pigeons), or increasing baselines (monkeys).

  5. Lockhart Clarke's contribution to the description of amyotrophic lateral sclerosis.

    PubMed

    Turner, Martin R; Swash, Michael; Ebers, George C

    2010-11-01

    The definition of the clinicopathological entity of amyotrophic lateral sclerosis evolved over half a century. Although the definitive term amyotrophic lateral sclerosis that acknowledged both upper and lower motor neuron involvement was attributed to Jean-Martin Charcot in 1874, his initial case was published nearly a decade earlier; and it is accepted that, from at least the 1830s, several others (including Charles Bell, François-Amilcar Aran and Jean Cruveilhier) had already recognized a progressive lower motor neuron-only syndrome within a broader, clinically-defined group of disorders, termed progressive muscular atrophy. Although William Gowers first grouped the three phenotypes of amyotrophic lateral sclerosis, progressive muscular atrophy and progressive bulbar palsy together as part of the same syndrome, the term motor neuron disease, as an over-arching label, was not suggested until nearly a century later by W. Russell Brain. Augustus Jacob Lockhart Clarke (1817-80) is best known for his descriptions of spinal cord anatomy. However, in two detailed case reports from the 1860s, he carried out rigorous post-mortem neuropathological studies of what appear to be classical cases of amyotrophic lateral sclerosis. Furthermore, he recognized the additional involvement of the corticospinal tracts that distinguished this from progressive muscular atrophy. Several aspects of the exquisite clinical histories documented as part of both studies, one by Charles Bland Radcliffe, resonate with contemporary debates concerning the evolution of disease in amyotrophic lateral sclerosis. These 'past masters' still have much to teach us. PMID:20576696

    1996-01-01

    A ground-water flow model was used in conjunction with particle tracking to evaluate ground-water vulnerability in Clark County, Washington. Using the particle-tracking program, particles were placed in every cell of the flow model (about 60,000 particles) and tracked backwards in time and space upgradient along flow paths to their recharge points. A new computer program was developed that interfaces the results from a particle-tracking program with a geographic information system (GIS). The GIS was used to display and analyze the particle-tracking results. Ground-water vulnerability was evaluated by selecting parts of the ground-water flow system and combining the results with ancillary information stored in the GIS to determine recharge areas, characteristics of recharge areas, downgradient impact of land use at recharge areas, and age of ground water. Maps of the recharge areas for each hydrogeologic unit illustrate the presence of local, intermediate, or regional ground-water flow systems and emphasize the three-dimensional nature of the ground-water flow system in Clark County. Maps of the recharge points for each hydrogeologic unit were overlaid with maps depicting aquifer sensitivity as determined by DRASTIC (a measure of the pollution potential of ground water, based on the intrinsic characteristics of the near-surface unsaturated and saturated zones) and recharge from on-site waste-disposal systems. A large number of recharge areas were identified, particularly in southern Clark County, that have a high aquifer sensitivity, coincide with areas of recharge from on-site waste-disposal systems, or both. Using the GIS, the characteristics of the recharge areas were related to the downgradient parts of the ground-water system that will eventually receive flow that has recharged through these areas. The aquifer sensitivity, as indicated by DRASTIC, of the recharge areas for downgradient parts of the flow system was mapped for each hydrogeologic unit. A number of

    A northeast-trending magnetic anomaly in parts of Beaverhead and Madison Counties, Mont., and Clark County, Idaho, may reflect the trend, shape, and size of a concealed pluton. The type of rock that forms the pluton(?) is unknown. A small volcanic pipe, possibly a diatreme, is at the southeast end of the high. The pipe, about 92 m (300 ft) in diameter, consists of a rubbly basalt-like matrix through which are scattered xenoliths of Precambrian crystalline rocks and of various Paleozoic and Mesozoic strata. It is uncertain whether the juxtaposition of the pipe and the magnetic high is meaningful or is merely fortuitous. Although no mineralized rock was found in the area underlain by the anomaly, placer gold has been found nearby. Some 113 km (70 mi) to the west, in Custer and Lemhi Counties, Idaho, a similar northeast-trending magnetic high marks the site of the Gilmore mining district. The similarities in trend, shape, and magnitude between the two anomalies suggest that the high in Beaverhead and Madison Counties should be investigated for undetected mineral deposits, possibly by a geochemical survey.

  10. Discipline and credibility in the post-war australopithecine controversy: Le Gros Clark versus Zuckerman.

    PubMed

    Richmond, Jesse

    2012-01-01

    Paleoanthropologists and outside commentators have often remarked upon the apparent difficulty of securing shared belief among experts in the science of human evolution. The field has been and continues to be particularly prone to disagreement and even controversy among its practitioners to a degree that sets it apart from other areas of scientific inquiry. The fact that the field lies at the intersection of a number of disciplines may help to explain this predicament. Displays of discipline serve as an important resource for scientists as they work to secure credibility. Where a field of inquiry spans a host of disciplinary approaches, there can be disagreement about the kind of disciplined behavior appropriate to making credible claims about that field's subject matter. A conflict of this sort emerged after WW II over the claim that the australopithecines of South Africa represented a likely ancestral link in the evolution of human beings. W. E. Le Gros Clark, working in the established disciplinary tradition of comparative anatomy, endorsed the claim of ancestry, while Solly Zuckerman, reflecting his recent immersion in war-time operations research, criticized that claim on the grounds that it came without the rigorous quantitative demonstration that he felt was the hallmark of a properly disciplined science.

  15. Female Lincoln's sparrows modulate their behavior in response to variation in male song quality

    2010-01-01

    Sexually reproducing organisms should mate with the highest quality individuals that they can. When female songbirds choose a mate, they are thought to use several aspects of male song that reflect his quality. Under resource-limited environmental conditions, male Lincoln's sparrows (Melospiza lincolnii) vary among one another in several aspects of song quality, including song length, song complexity, and trill performance. In a 2-pronged approach, we tested whether variation in song quality of male Lincoln's sparrows influences the behavior of females that are in a reproductive-like state. Over two trials, we exposed females to songs from the high and low ends of the distribution of naturally occurring song quality variation and found a higher level of behavioral activity in females exposed to high-quality songs, especially when they had first been exposed to low-quality songs. We also examined female phonotaxis toward antiphonally played songs with experimentally elevated and reduced trill performance and found that females moved preferentially toward the songs with elevated trill performance. Contrary to most studies investigating the behavioral responses of wild, female songbirds to variation in male song, we obtained our results without administering exogenous estradiol, which can artificially perturb the female's physiology. Our results demonstrate that the behavior of female Lincoln's sparrows is modulated by the quality of male songs to which they are exposed and that trill performance plays a significant role in this behavioral modulation. Furthermore, as the order of song quality presentation matters, it appears that recent song experience also influences female behavior. PMID:22476505

  17. Historical perspectives on channel pattern in the Clark Fork River, Montana and implications for post-dam removal restoration

    NASA Astrophysics Data System (ADS)

    Woelfle-Erskine, C. A.; Wilcox, A. C.

    2009-12-01

    Active restoration approaches such as channel reconstruction have moved beyond the realm of small streams and are being applied to larger rivers. Uncertainties arising from limited knowledge, fluvial and ecosystem variability, and contaminants are especially significant in restoration of large rivers, where project costs and the social, infrastructural, and ecological costs of failure are high. We use the case of Milltown Dam removal on the Clark Fork River, Montana and subsequent channel reconstruction in the former reservoir to examine the use of historical research and uncertainty analysis in river restoration. At a cost of approximately $120 million, the Milltown Dam removal involves the mechanical removal of approximately 2 million cubic meters of sediments contaminated by upstream mining, followed by restoration of the former reservoir reach in which a single-thread meandering channel is being constructed. Historical maps, surveys, photographs, and accounts suggest a conceptual model of a multi-thread, anastomosing river in the reach targeted for channel reconstruction, upstream of the confluence of the Clark Fork and Blackfoot Rivers. We supplemented historical research with analysis of aerial photographs, topographic data, and USGS stage-discharge measurements in a lotic but reservoir-influenced reach of the Clark Fork River within our study area to estimate avulsion frequency (0.8 avulsions/year over a 70-year period) and average rates of lateral migration and aggradation. These were used to calculate the mobility number, a dimensionless relationship between channel filling and lateral migration timescales that can be used to predict whether a river’s planform is single or multi-threaded. The mobility number within our study reach ranged from 0.6 (multi-thread channel) to 1.7 (transitional channel). We predict that, in the absence of active channel reconstruction, the post-dam channel pattern would evolve to one that alternates between single and multi

    The ALCOA (also known as Vancouver Smelter) site, located on the northern bank of the Columbia River about 4 miles west of Interstate 5 in Vancouver, Clark County, Washington, has been proposed for the National Priorities List. The site consists of three waste piles containing about 66,000 tons of waste (spent potlinings and alumina insulation) that were deposited on the north bank of the Columbia River by ALCOA between 1973 and 1981. ALCOA has since sold the aluminum smelter to another company, VANALCO. The contaminants detected in the groundwater in the area surrounding the piles include cyanide, fluoride, and trichloroethene (TCE). The ALCOA site is of potential public health concern because humans may be exposed to hazardous substances at concentrations that may result in adverse health effects.

    SciTech Connect

    1992-06-18

    The Systems Development Report represents the third major step in the Clark County Socioeconomic Impact Assessment of the Proposed High-Level Nuclear Waste Repository at Yucca Mound Nevada. The first of these steps was to forge a Research Design that would serve as a guide for the overall research process. The second step was the construction of the Base Case, the purpose of which was to describe existing conditions in Clark County in the specified analytic areas of Economic-Demographic/Fiscal, Emergency Planning and Management, Transportation and Sociocultural analysis. The base case description will serve as a basis for assessing changes in these topic areas that might result from the Yucca Mountain project. These changes will be assessed by analyzing conditions with and without repository development in the county. Prior to performing such assessments, however, the snapshot type of data found in the base case must be operationalized or systematized to allow for more dynamic data utilization. In other words, a data system that can be used to analyze the consequences of the introduction of different variables (or variable values) in the Clark County context must be constructed. Such a system must be capable of being updated through subsequent data collection and monitoring efforts to both provide a rolling base case and supply information necessary to construct trend analyses. For example, during the Impact Assessment phase of the study process, the without repository analysis is accomplished by analyzing growth for the county given existing conditions and likely trends. These data are then compared to the with Yucca Mountain project conditions anticipated for the county. Similarly, once the emergency planning management and response needs associated with the repository are described, these needs will be juxtaposed against existing (and various future) capacity(ies) in order to determine the nature and magnitude of impacts in this analytic area.

    Three multi-parameter water-quality monitors equipped with either Clark cell type or optical type dissolved-oxygen sensors were deployed for 30 days in a brackish (salinity <10 parts per thousand) environment to determine the sensitivity of the sensors to biofouling. The dissolved-oxygen sensors compared periodically to a hand-held dissolved oxygen sensor, but were not serviced or cleaned during the deployment. One of the Clark cell sensors and the optical sensor performed similarly during the deployment. The remaining Clark cell sensor was not aged correctly prior to deployment and did not perform as well as the other sensors. All sensors experienced substantial biofouling that gradually degraded the accuracy of the dissolved-oxygen measurement during the last half of the deployment period. Copyright ASCE 2005.

  1. The Lincoln Laboratory-Aerospace Medical Research Laboratory digital speech test facility

    1984-05-01

    A narrowband digital speech communication test facility has been established and operates between Lincoln Laboratory and the Wright-Patterson Aerospace Medical Research Laboratory. Noise fields simulating the acoustic environments of E3A and F-15 aircraft are established and Air Force personnel use the link operating at 2400 bps with a vocoder designed at Lincoln Laboratory, and a commercial telephone line modem. The facility includes a digital signal processing computer which can introduce bit errors and delay into the transmit and receive data. Communication scenarios are used to exercise the vocoder-modem channel with the dynamics and vocabulary of typical operational exchanges. Answers to a standard questionnaire provide acceptability data for the 2400 bps JTIDS class 2 voice channel. For the tests run so far, the 2400 bps voice is acceptable in the sense of positive user response to the questionnaire. Further testing using error and delay simulations will follow. An F-15 to F-15 link will be simulated at AMRL using a pair of vocoders operating back-to-back and in separate noise chambers.

  2. Assessment of chronic toxicity from stormwater runoff in Lincoln Creek, Milwaukee, WI

    Stormwater runoff is believed to be responsible for a severely degraded biotic community in Lincoln Creek, a stream which drains portions of metropolitan Milwaukee. A previous study using Ceriodaphnia dubia and Pimephales promelas indicated little or no acute toxicity could be attributed to stormwater runoff. The purpose of this study was to assess the potential for chronic toxicity in the stream during periods of stormwater runoff. Reproduction and survival in Daphnia magna, and growth and survival in P. promelas were monitored to assess chronic effects. Seven consecutive 14 day tests were performed between June and September, 1994, in eighteen flow-through aquaria housed within a US Geological Survey gauging station located adjacent to Lincoln Creek. Mortality in D. magna consistently did not occur before day 4 of exposure, but averaged 64% at day 14. Reproduction in D. magna and growth in P. promelas in surviving individuals was not significantly reduced; all effects were manifested as mortality. Results of data analysis after 14 days of exposure contrast markedly with analysis made earlier in the same test. Statistical interpretation of the mortality data at typical endpoints of 48 hours for invertebrates and 96 hours for fish failed to identify adverse impacts of stormwater runoff the authors observed in longer exposures. Short-term toxicity tests appear insensitive to the detection of contaminant related effects. Long-term tests (greater than 7 days) were needed to identify adverse biological impacts that could in part explain the severely degraded biotic community of this urban stream.

  3. Logical and physical simulation of heavy vehicle automation: a case study of the Lincoln Tunnel

    1998-01-01

    Rising with the expansion of today's transportation systems are needs for new techniques to handle the increasing demand load. This includes the development of Intelligent Transportation Systems (ITS) to incorporate modern technology into creating flexible transportation systems which react more efficiently to traffic problems. A particular focus is the creation of an Automated Highway System (AHS) to combine advanced sensing and communication technologies to create highly efficient computer-controlled traffic flow. At present, many complex dimensions of automated highway development remain difficult to mange. To develop an evolutionary step toward an automated highway, increasing traffic flow in a highly controlled environment is essential. The Lincoln Tunnel, a Hudson River crossing between New York City and New Jersey, represents a major artery to thousands of commuters living in New Jersey. The Port Authority of New York and New Jersey, the governing authority of the Lincoln Tunnel, has dedicated certain priority lanes for bus traffic to streamline traffic flow and create a reward process for mass transit commuters. It is possible to increase flow efficiency using existing technology to control vehicle motion through this corridor. This paper provides a description of physical simulation testing the feasibility of automating lanes for bus flow on this roadway.

  4. A Heuristic Approach Based on Clarke-Wright Algorithm for Open Vehicle Routing Problem

    PubMed Central

    2013-01-01

    We propose a heuristic approach based on the Clarke-Wright algorithm (CW) to solve the open version of the well-known capacitated vehicle routing problem in which vehicles are not required to return to the depot after completing service. The proposed CW has been presented in four procedures composed of Clarke-Wright formula modification, open-route construction, two-phase selection, and route postimprovement. Computational results show that the proposed CW is competitive and outperforms classical CW in all directions. Moreover, the best known solution is also obtained in 97% of tested instances (60 out of 62). PMID:24382948

  13. A Dynamic Optimization Technique for Siting the NASA-Clark Atlanta Urban Rain Gauge Network (NCURN)

    NASA Technical Reports Server (NTRS)

    Shepherd, J. Marshall; Taylor, Layi

    2003-01-01

    NASA satellites and ground instruments have indicated that cities like Atlanta, Georgia may create or alter rainfall. Scientists speculate that the urban heat island caused by man-made surfaces in cities impact the heat and wind patterns that form clouds and rainfall. However, more conclusive evidence is required to substantiate findings from satellites. NASA, along with scientists at Clark Atlanta University, are implementing a dense, urban rain gauge network in the metropolitan Atlanta area to support a satellite validation program called Studies of PRecipitation Anomalies from Widespread Urban Landuse (SPRAWL). SPRAWL will be conducted during the summer of 2003 to further identify and understand the impact of urban Atlanta on precipitation variability. The paper provides an. overview of SPRAWL, which represents one of the more comprehensive efforts in recent years to focus exclusively on urban-impacted rainfall. The paper also introduces a novel technique for deploying rain gauges for SPRAWL. The deployment of the dense Atlanta network is unique because it utilizes Geographic Information Systems (GIS) and Decision Support Systems (DSS) to optimize deployment of the rain gauges. These computer aided systems consider access to roads, drainage systems, tree cover, and other factors in guiding the deployment of the gauge network. GIS and DSS also provide decision-makers with additional resources and flexibility to make informed decisions while considering numerous factors. Also, the new Atlanta network and SPRAWL provide a unique opportunity to merge the high-resolution, urban rain gauge network with satellite-derived rainfall products to understand how cities are changing rainfall patterns, and possibly climate.

  14. A time-efficient algorithm for implementing the Catmull-Clark subdivision method

    NASA Astrophysics Data System (ADS)

    Ioannou, G.; Savva, A.; Stylianou, V.

    2015-10-01

    Splines are the most popular methods in Figure Modeling and CAGD (Computer Aided Geometric Design) in generating smooth surfaces from a number of control points. The control points define the shape of a figure and splines calculate the required number of points which when displayed on a computer screen the result is a smooth surface. However, spline methods are based on a rectangular topological structure of points, i.e., a two-dimensional table of vertices, and thus cannot generate complex figures, such as the human and animal bodies that their complex structure does not allow them to be defined by a regular rectangular grid. On the other hand surface subdivision methods, which are derived by splines, generate surfaces which are defined by an arbitrary topology of control points. This is the reason that during the last fifteen years subdivision methods have taken the lead over regular spline methods in all areas of modeling in both industry and research. The cost of executing computer software developed to read control points and calculate the surface is run-time, due to the fact that the surface-structure required for handling arbitrary topological grids is very complicate. There are many software programs that have been developed related to the implementation of subdivision surfaces however, not many algorithms are documented in the literature, to support developers for writing efficient code. This paper aims to assist programmers by presenting a time-efficient algorithm for implementing subdivision splines. The Catmull-Clark which is the most popular of the subdivision methods has been employed to illustrate the algorithm.

  17. The Legacy of Clark Lake and the Road to the Long Wavelength Array

    NASA Astrophysics Data System (ADS)

    Kassim, N. E.; Polisensky, E. J.

    2005-12-01

    Over a period of nearly three decades, Bill Erickson, together with a hardy group of innovators and their collective students, developed a series of pioneering instruments in the dry lake bed of Clark Lake east of San Diego. The last of those was the Clark Lake TPT - a broad-band, completely electronic instrument that will be surpassed in sophistication only when the emerging suite of new low-frequency instruments, such as the Long Wavelength Array (LWA) and the Low Frequency Array (LOFAR), are finally built. In the intervening decade since the Clark Lake Radio Observatory (CLRO) closed in the early 1990s, there has been a quiet renaissance of low-frequency radio astronomy. It has been motivated, in part, both by people trained at the CLRO and by a growing recognition that a variety of key astrophysical questions require observations at low radio frequencies. I summarize the positive legacy of Clark Lake, and Bill Erickson's work, that presaged the emergence of this long neglected field into the mainstream of modern astronomy.

    Stoeckel, Gerhard P.; Doyle, Keith B.

    2013-09-01

    Advanced analytical software capabilities are being developed to advance the design of prototypical hardware in the Engineering Division at MIT Lincoln Laboratory. The current effort is focused on the integration of analysis tools tailored to the work flow, organizational structure, and current technology demands. These tools are being designed to provide superior insight into the interdisciplinary behavior of optical systems and enable rapid assessment and execution of design trades to optimize the design of optomechanical systems. The custom software architecture is designed to exploit and enhance the functionality of existing industry standard commercial software, provide a framework for centralizing internally developed tools, and deliver greater efficiency, productivity, and accuracy through standardization, automation, and integration. Specific efforts have included the development of a feature-rich software package for Structural-Thermal-Optical Performance (STOP) modeling, advanced Line Of Sight (LOS) jitter simulations, and improved integration of dynamic testing and structural modeling.

  19. Thirty years of research and development in space communications at Lincoln Laboratory

    NASA Astrophysics Data System (ADS)

    Ward, William W.; Floyd, Franklin W.

    The MIT Lincoln Laboratory's 30-year history of development efforts toward the routine availability of long-range military communications has evolved in the direction of achieving space communications on military channels that are electromagnetically and physically survivable despite the most determined efforts of an adversary to interfere through jamming or physical attack. Toward these ends, and representative of the Laboratory's innovativeness, an experiment was proposed to demonstrate transcontinental communications by sending simultaneous transmissions to and from terminals at Camp Parks, California, and Westford, Massachusetts. The orbiting scatterers for these transmissions would act as half-wave dipoles and resonate at about 8 GHz; the experiment would require that about 480 million of these 40-microgram dipoles, amounting to 19 kg of copper, be distributed into circular polar orbits at an altitude of about 3600 km. The full range of satellite-communications developments over the 30-year period is surveyed.

  20. The standoff aerosol active signature testbed (SAAST) at MIT Lincoln Laboratory

    NASA Astrophysics Data System (ADS)

    Richardson, Jonathan M.; Aldridge, John C.

    2005-11-01

    Standoff LIDAR detection of BW agents depends on accurate knowledge of the infrared and ultraviolet optical elastic scatter (ES) and ultraviolet fluorescence (UVF) signatures of bio-agents and interferents. MIT Lincoln Laboratory has developed the Standoff Aerosol Active Signature Testbed (SAAST) for measuring ES cross sections from BW simulants and interferents at all angles including 180º (direct backscatter). Measurements of interest include the dependence of the ES and UVF signatures on several spore production parameters including growth medium, sporulation protocol, washing protocol, fluidizing additives, and degree of aggregation. Using SAAST, we have made measurements of the ES signature of Bacillus globigii (atropheaus, Bg) spores grown under different growth methods. We have also investigated one common interferent (Arizona Test Dust). Future samples will include pollen and diesel exhaust. This paper presents the details of the SAAST apparatus along with the results of recent measurements.

    SciTech Connect

    Zey, J.N.; Elliott, L.; Mortimer, V.

    1987-07-01

    A request was received from Clark County Hospital located in Jeffersonville, Indiana to evaluate possible employee exposures to hazardous substances while working in the central-supply (CS) area. Symptoms expressed by workers included headaches, dizziness, mucous membrane irritation, vomiting, diarrhea, nose bleeds, fatigue, nervous problems, and respiratory difficulties. Workers had reported smelling a sweet odor at times. Air sampling yielded time-weighted average personal-exposure concentrations of 0.23 to 0.56 parts per million (ppm) for ethylene oxide with short-term exposures of 77 ppm in the cart-storage area. The OSHA standard was 1 ppm, and the NIOSH recommended criterion was 0.1 ppm of ethylene oxide. Hydrochloric acid concentrations in area air samples were less than 1.0 ppm; for chlorine gas, less than 0.2 ppm; for carbon monoxide, less than 5.0 ppm; and up to 700 ppm for carbon dioxide. The lack of a dedicated ethylene oxide exhaust and the existence of an overloaded exhaust system were noted. The authors conclude that a health hazard to workers from exposure to ethylene oxide existed. They recommend specific measures to reduce exposures to ethylene oxide, including design and installation of a proper ventilation system.

  2. Diel changes in stable carbon isotope ratios and trace element concentrations in the Clark Fork River, MT.

    NASA Astrophysics Data System (ADS)

    Parker, S.; Gammons, C.; Degrandpre, M.

    2004-12-01

    A diel (24-hr) water sampling was conducted on the Clark Fork River near Deer Lodge, Montana from 31-July to 1-August of 2003. The Clark Fork River is located in southwestern Montana and its upper reaches have been heavily affected by historic mining and smelting activities in the Butte and Anaconda areas. River floodplains and sediment beds contain significant quantities of metals (iron, aluminum, copper, zinc, lead, cadmium.) and arsenic. Two sites about 1.2 km apart, were sampled with a mean transit time for the water of 2.5 hours between the sites. The river in the study reach is characterized by oxic conditions, moderate alkalinity, moderate biological productivity and a pH range of about 8.0 to 8.5 during the summer low water months. During the mid-summer months, water in the Clark Fork River and its tributary streams is diverted for irrigation. Some of this water returns to the main stem in a chemically modified form as surface or groundwater return flow. This greatly complicates the hydrogeology and nutrient balance of the watershed. The two samplings sites used in this study make it possible to analyze the changes in chemical and physical properties of the water as it travels between the sites. Results reported here show that there is a large degree of temporal and spatial variability across the study area. In situ instruments were deployed and hourly water samples were collected for analysis from both sites. Diel concentration cycles are documented for dissolved forms of manganese, zinc and nitrate. Particulate forms of zinc, aluminum, copper, iron and manganese are shown to undergo twenty-four hour concentration changes.

    There is always something needed for a NASA aircraft before a research flight can take place. This photo shows William J. Clark working on one of those 'somethings' while Jimmie C. Lewis watches ready to help. Working on a research project is a challenge, for there is no set pattern to follow. From the drawings to the final product there are many people who contribute to that final product -- the flight. The electronic technicians in the Instrumentation Laboratory at NASA Ames-Dryden Flight Research Facility are no exception. Bill Clark is busy creating a cannon plug to be used on the CV-990. He is soldering wires in the appropriate order so the plug will transmit electrical currents correctly when installed in the airplane. Jim stands by to give help and support on the project.

    The avoidance response of brown trout (Salmo trutta) to mixtures of cadmium, copper, lead, and zinc was determined in water simulating the Clark Fork River, Montana. Effects of acidification on the avoidance response were also evaluated. Tests were conducted in a cylindrical chamber that received reference water at one end and metal-contaminated water at the other; a distinct boundary formed at the center where the chamber drained. A 1 × mixture of the four metals (Cd, 1.1 μg/L; Cu, 12 μg/L; Pb, 3.2 μg/L; and Zn, 55 μg/L) that was representative of the ambient metals concentrations of the Clark Fork River resulted in avoidance by brown trout. Brown trout also avoided 0.5×, 2×, 4×, and 10× mixtures but not a 0.1 × mixture. A reduction in pH from 8.0 to either 7.0, 6.0, or 5.0 resulted in significant avoidance. Avoidance reactions to metals, similar to those observed in our laboratory experiments, may contribute to the depression of brown trout populations in the Clark Fork River.

    In 1899, at the invitation of G. Stanley Hall, the great psychologist and President of Clark University, Santiago Ramón y Cajal, and four other European scientists of significant note, were invited to participate in the Decennial Celebration of Clark. Cajal, accompanied by his wife, arrived in Worcester, via New York, to much acclaim and praise in the local press. His three lectures, all delivered in French and illustrated with large color drawings made upon his arrival at Clark, were concerned with previously unpublished observations on the structure of the human cerebral cortex. The full text of these lectures and 31 illustrations (in black and white) were published, in English, in a large Decennial Volume prepared by Clark University. At the culmination of the Clark Celebration, Cajal, and the other invited attendees, received the honorary Doctor of Laws degree. Cajal, ever the scholar, visited many sites of interest in the Northeastern US prior to his return to Spain including Columbia, Harvard, and the University of New York. This paper details the events surrounding Cajal's visit to Clark University, his only visit to the United States. PMID:17408560

    Concentrations of metals in sediments and soils deposited along the floodplain of the Clark Fork River, within the Grant-Kohrs Ranch National Historic Site, Deer Lodge, Montana, USA, have exceeded maximum background concentrations in the United States for most metals tested. As a result of mining and smelting activities, portions of the Deer Lodge Valley, including the Grant-Kohrs Ranch, have received National Priority List Designation under the Comprehensive Environmental Response, Compensation and Liability Act. Using a series of plant germination tests, pH measurements, and metal analyses, this study investigated the toxicity of soils from floodplain slicken areas, bare spots devoid of vegetation, along the Clark Fork River. The slicken soils collected from the Grant-Kohrs Ranch were toxic to all four plant species tested. The most sensitive endpoint in the germination tests was root length and the least sensitive was emergence. Considering emergence, the most sensitive species was the resident grass species Agrostis gigantea. The sensitivities were reversed when root lengths were examined, with Echinochloa crusgalli showing the greatest sensitivity. Both elevated concentrations of metals and low pH were necessary to produce an acutely phytotoxic response in laboratory seed germination tests using slicken soils. Moreover, pH values on the Grant-Kohrs Ranch appear to be a better predictor of acutely phytotoxic conditions than total metal levels.

    Sediments of the upper Clark Fork River, from the Butte and Anaconda area to Milltown Reservoir (230 km downstream), are contaminated with As, Cd, Cu, Pb, Mn, and Zn primarily from mining activities. The toxicity of pore water from these sediments was determined using Daphnia magna, rainbow trout, and Microtox[reg sign]. However, pore-water data from these exposures were questionable because of changes in the toxicity of pore-water samples after 5 to 7 d of storage. Whole-sediment tests were conducted with Hyalella azteca, Chironomus riparius, rainbow trout (Oncorhynchus mykiss) 21- to 28-d exposure and Daphnia magna. Sediment samples from Milltown Reservoir and the Clark Fork River were not generally lethal to test organisms. However, both reduced growth and delayed sexual maturation of amphipods were associated with exposure to elevated concentrations of metals in sediments from the reservoir and river. Relative sensitivity (most sensitive to least sensitive) of organisms in whole-sediment toxicity tests was: Hyalella azteca > Chironomus riparius > rainbow trout > Daphnia magna. Relative sensitivity (most sensitive to least sensitive) of the three end points evaluated with Hyalella azteca was: length > sexual maturation > survival. The lack of lethal effects on organisms may be related to temporal differences in sediment, acid-volatile sulfide, or organic carbon.

  16. Hydrographic changes in the Lincoln Sea in the Arctic Ocean with focus on an upper ocean freshwater anomaly between 2007 and 2010

    Hydrographic data from the Arctic Ocean show that freshwater content in the Lincoln Sea, north of Greenland, increased significantly from 2007 to 2010, slightly lagging changes in the eastern and central Arctic. The anomaly was primarily caused by a decrease in the upper ocean salinity. In 2011 upper ocean salinities in the Lincoln Sea returned to values similar to those prior to 2007. Throughout 2008-2010, the freshest surface waters in the western Lincoln Sea show water mass properties similar to fresh Canada Basin waters north of the Canadian Arctic Archipelago. In the northeastern Lincoln Sea fresh surface waters showed a strong link with those observed in the Makarov Basin near the North Pole. The freshening in the Lincoln Sea was associated with a return of a subsurface Pacific Water temperature signal although this was not as strong as observed in the early 1990s. Comparison of repeat stations from the 2000s with the data from the 1990s at 65°W showed an increase of the Atlantic temperature maximum which was associated with the arrival of warmer Atlantic water from the Eurasian Basin. Satellite-derived dynamic ocean topography of winter 2009 showed a ridge extending parallel to the Canadian Archipelago shelf as far as the Lincoln Sea, causing a strong flow toward Nares Strait and likely Fram Strait. The total volume of anomalous freshwater observed in the Lincoln Sea and exported by 2011 was close to 1100±250km3, approximately 13% of the total estimated FW increase in the Arctic in 2008.

  17. The norm and the text: Denzin and Lincoln's handbooks of qualitative method.

    PubMed

    Fielding, N G

    1999-09-01

    Qualitative methods have lately enjoyed enhanced legitimacy and are increasingly used in academic and applied social research. Yet the field is marked by controversy about virtually every key tenet of qualitative inquiry, from matters of epistemology to purely practical matters of relations with research subjects. Not only is the practice of qualitative research hotly contested, consensus is lacking about the purpose of qualitative research and whether it has a distinctive role to play relative to other approaches to the study of social phenomena. Against this context, the handbooks of qualitative method edited by Norman Denzin and Yvonna Lincoln represent a significant attempt to capture the breadth of contemporary approaches to qualitative method. The article examines key contributions from the handbooks, drawing on these to develop a view of qualitative method from a pragmatic, realist perspective. Among the issues considered are the significance of relativism, subjectivity, post-modernism and feminist method, the politicization of the purposes of qualitative research, the debate over criteria of validity, and the move to treat qualitative research as an entertainment rather than a scientific practice.

    Dr. Adalbert Volck, a native of Bavaria, Germany, was a man of many talents: he was a skilled, innovative and versatile dentist, artist, artisan, craftsman, and a Confederate Civil War cartoonist and caricaturist. In 1848, after participating in a national revolution gone sour, Volck emigrated to the U.S. In 1852, Volck received his DDS degree from the Baltimore College of Dental Surgery, and subsequently, he established a life-long residency and dental practice in Baltimore. Dr. Volck gave staunch support to the spirit and force of organized dentistry. Among his professional accomplishments was his work in the early development of dental porcelain restorations. Although he was a non-combatant in the U.S. Civil War, Volck demonstrated his loyalty to the Southern cause by becoming a blockade runner; smuggler of drugs and medical supplies; "safe house" operator for Confederate soldiers and agents; Rebel spy; and personal courier for Jefferson Davis (the President of the Confederacy). The popular anti-Confederacy political cartoons of the great Thomas Nast inspired Volck to execute similar lampoons against the Union. Early in the war, Volck, through his caricatures, attacked the person and policies of President Lincoln and his Northern leaders. By using irony, sarcasm and ridicule, Volck attempted to sway popular sentiment toward the South. PMID:11569060

    Eleven sets of samples from five sites on Antelope Creek and Dead Man 's Run in Lincoln, Nebraska, were collected from December 1982 through June 1983 to study water-quality variations. Specific-conductance values generally were similar for Antelope Creek at 52nd Street and 27th Street, but during a low-flow survey of December 1 they increased from 974 to 8,700 microsiemens per centimeter at 25 C from 27th Street to Court Street. Seepage of saline water from underlying bedrock to the stream occurs in this reach. Specific-conductance values were less variable for Dead Man 's Run, increasing an average of only 47 percent from 66th Street to U.S. Highway 6. Specific-conductance values were less at high flows in Antelope Creek, except in samples collected on January 6, 1983, which contained runoff from salted streets. Sodium and chloride concentrations in these samples were from 5 to 10 times greater than those measured in any other samples. Stray-current corrosion occurs when current flows between dissimilar metals. Zinc-coated wire of channel-stabilization structures (gabions) may be an anode and material within the stream banks may be a cathode. Dissolution of the zinc coating by this type of corrosion may be a cause for gabion deterioration in both streams. (USGS)

    Based on the testimony of others, children learn about a variety of figures that they never meet. We ask when and how they are able to differentiate between the historical figures that they learn about (e.g., Abraham Lincoln) and fantasy characters (e.g., Harry Potter). Experiment 1 showed that both younger (3- and 4-year-olds) and older children (5-, 6-, and 7-year-olds) understand the status of familiar figures, correctly judging historical figures to be real and fictional figures to be pretend. However, when presented with information about novel figures embedded in either a realistic narrative or a narrative with obvious fantasy elements, only older children used the narrative to make an appropriate assessment of the status of the protagonist. In Experiment 2, 3-, and 4-year-olds were prompted to judge whether the story events were really possible or not. Those who did so accurately were able to deploy that judgment to correctly assess the status of the protagonist. PMID:19766203

    The purpose of this project was to evaluate the freshwater resources and possible sources of high-chloride and high-sulfate concentrations in parts of the aquifer near the Sac and Fox Nation tribal land in eastern Lincoln County, Oklahoma. Water-quality sampling and borehole geophysical data indicate the potential for fresh ground water on tribal land generally is greatest in the Vanoss Formation, in the SE1/4 sec. 21, T. 14 N., R. 06 E. and in the NE1/4 sec. 22, T. 14 N., R. 06 E. These locations avoid the flood-prone areas and borehole geophysical resistivity logs indicate the altitude of the base of fresh ground water is below 650 ft. The altitude of the base of fresh ground water is indicated to be generally near the surface under the W1/2 sec. 22, T. 14 N., R. 06 E., the SE1/4 sec. 22, SE1/4 SE1/4 NE1/4 sec. 21, and NE1/4 NW1/4 NW1/4 sec. 27. Conditions are more favorable for placement of fresh ground-water wells in sec. 34, T. 14 N., R. 06 E., where the tribe has leased water rights, than on tribal land in secs. 15, 16, 21, and 22, T. 14 N., R. 06 E. Sandstones overlain by or enclosed in thick clay and shale sequences are likely to be somewhat isolated from the flow system and retain some of the residual brine. Borehole geophysical logs suggest that sandstones near CH1, CM1, and WT1 have more clay and shale content than the sandstones near L2. Greater amounts of clay in the sandstones will retard the flushing of residual brines from the sandstones and could result in a shallow base of fresh water near CH1, CM1, and WT1. For these reasons and because circulation of fresh ground water is limited by discharge to the Deep Fork, general water quality under tribal land would probably be poorer than in the area where the tribe has leased water rights. Samples have chloride or sulfate concentrations greater than 250 milligrams per liter in the W1/2 sec. 22, T. 14 N., R. 06 E. Six cluster well samples from tribal land have chloride or sulfate concentrations above the

    Osprey (Pandion haliaetus) are widely recognized as bio-indicators of the health of aquatic ecosystems. Until the time of fledging, nestlings feed exclusively on fish caught within a few kilometers of the nest. Therefore, tissues of these young birds may reflect the level of contamination of local fish and more generally, the contamination status of the aquatic ecosystem they inhabit. Nests can often be accessed with a boom truck and obtaining small blood samples from the flightless chicks is fairly noninvasive. Ospreys are nesting along the Upper Clark Fork River, Montana, which is heavily contaminated with wastes left from a century of copper and precious metals mining. We have been monitoring the levels of priority pollutants (arsenic, cadmium, lead, copper, zinc, mercury and selenium) in Osprey chicks along a 250 km section of the river for four years. Objectives are to establish current contaminant status, pinpoint pollution hotspots, and assess the success of restoration efforts. Our results suggest that of highest concern may be the bioaccumulation of mercury with blood levels of up to 0.7 mg/L in the growing chicks. These concentrations are expected to increase many fold upon fledging as feather growth stops, which acts as the major sink for mercury. Interestingly, we found mercury levels increased in downstream direction, in contrast to concentrations of other pollutants. Reasons may be the different origin of mercury versus other contaminants and the distribution of wetlands where mercury can be transformed into highly bioavailable methylmercury. Blood levels of selenium are also elevated throughout the Upper Clark Fork River drainage. We discuss the implications for restoration and remediation of the Clark Fork River.

  3. Regional significance of Mississippian rocks at Pentagon Mountain, Lewis and Clark Range, northwestern Montana

    Nichols, K.M.

    1985-05-01

    Pentagon Mountain exposes one of the best of the few sections of Mississippian rocks in the Lewis and Clark Range of northwestern Montana. This section consists of 225 m (738 ft) of marine carbonate rocks from which conodonts, ranging in age from earliest Osagean to early Meramecian, have been identified. Its stratigraphic base is well exposed, but the top has been eroded. Five units are recognized in this sequence, in ascending order: (1) phosphatized coarsely crinoidal and spiculitic wackestone, (2) dolomitic lime mudstone or wackestone, thinly interbedded with spiculitic biogenic chert, (3) partly dolomitized lime bioclastic wackestone showing much pressure-solution compaction, (4) partly dolomitized lime bioclastic packstone or wackestone, also showing much pressure-solution compaction, and (5) dolomitic mudstone. The Mississippian sequence at Pentagon Mountain can be readily correlated lithologically, across the Lewis thrust system with Mississippian rocks that crop out to the east in the Sawtooth Range. This implies either that Mississippian units were originally widespread or that the magnitude of thrusting between the Mississippian rocks in the Lewis and Clark Range and those in the Sawtooth Range was insignificant. However, Mississippian rocks at Pentagon Mountain exhibit extreme pressure-solution compaction, which suggests greater stratigraphic or structural burial of these rocks than their Mississippian counterparts in the Sawtooth Range. Secondary dolomite is pervasive in the lower part of the Mississippian section in the Lewis and Clark Range, and spectacular solution breccias locally disrupt the base of the section. These breccias and the adjacent dolomite are probably related, as both are thought to result from the passage of fluids through these rocks during Laramide uplift and/or post Laramide erosion and extension.

    Due to their rugged build, simplicity and cost effective performance, induction motors are used in a vast number of industries, where they play a significant role in responsible operations, where faults and downtimes are either not desirable or even unthinkable. As different faults can affect the performance of the induction motors, among them broken rotor bars, it is important to have a certain condition monitoring or diagnostic system that is guarding the state of the motor. This paper deals with induction motor broken rotor bars detection, using Clarke vector approach.

    Clarke, DeNora and Vuoskoski have carried out a formidable task of preparing a profound and encompassing review [3] that brings together two highly complex and multifaceted concepts, empathy and music, as well as a specific aspect of empathy that is highly relevant to society, cultural understanding. They have done an extraordinary service in synthesizing the growing, but still highly fragmented body of work in this area. At the heart of this review lies an intricate model that the authors develop, which accounts for a variety of mechanisms and cognitive processes underlying musical empathic engagement. In what follows I would like to first point out what I think is unique about this model. Then, I will briefly describe the need for including in any such model a developmental angle.

The {nu}{sub 2} vibrational band of water is detected with a signal-to-noise ratio of 11-50. Fitting the spectra using a fluorescence model of water emission yields a water rotational temperature of < 18 K for 71P/Clark and {approx_equal}14 {+-} 2 K (pre-perihelion) and 23 {+-} 4 K (post-perihelion) for C/2004 B1 (LINEAR). The water ortho-to-para ratio in C/2004 B1 (LINEAR) is measured to be 2.31 {+-} 0.18, which corresponds to a spin temperature of 26{sup +3} {sub -2} K. Water production rates are derived. The agreement between the water model and the measurements is good, as previously found for Spitzer spectra of C/2003 K4 (LINEAR). The Spitzer spectra of these three comets do not show any evidence for emission from polycyclic aromatic hydrocarbons and carbonate minerals, in contrast to results reported for comets 9P/Tempel 1 and C/1995 O1 (Hale-Bopp)

    along four routes that totaled 32 km. We examined bimonthly trends in the numbers of elk groups seen, the total number of elk seen, and the observed composition ratios for those six months of the year. The average number of elk groups seen per survey ranged from 0.75 (+/- 0.32 SE) during February to a peak of 1.95 (+/- 0.36 SE) during June. Despite this seasonal variation in numbers of elk groups seen, the average total number of elk seen per morning was less variable. The average ratios of antlered elk to antlerless adult elk (i.e., bulls:cows) and calves to antlerless adult elk (i.e. calves:cows) varied seasonally, with the highest of both average ratios observed in August. We detected no significant trends in the average number of elk groups and total numbers of elk seen per survey from 2008-2012. Similarly, ratios of calves and antlered elk per antlerless elk did not differ over time. Elk groups were frequently seen from January to August in the southeast region of the Fort Clatsop unit, in the vicinity of Colewort Creek. Outside of NPS lands, we observed elk most frequently in open areas near the Astoria regional airport, in the pastures and forests immediately north of the Fort Clatsop unit and, prior to the construction of a residential development, in a pasture northwest of the Fort Clatsop unit. Elk monitoring at Lewis and Clark NHP is still in its initial years and additional monitoring will be required to verify trends that appear to be emerging. For example, the initial monitoring suggested incipient declining trends in both pellet group density and proportion of plots with pellets present, as well as, potentially, a small shift in elk distribution away from a new trail that was recently constructed in the southeast portion of the Fort Clatsop unit. Continued monitoring will aid in determining whether this local change in distribution persists (or, alternatively, resulted from short-term random variation), and whether there will be any positive or negative

    2015-11-01

    Abraham Lincoln was the 16(th) President of the United States of America. On April 14, 1865, shortly after his re-election and the conclusion of the Civil War, Lincoln was shot and killed by John Wilkes Booth. Although numerous physicians tended to the President shortly after his injury, he passed away the next morning. Today, we recognize Lincoln as one of the greatest Presidents in American history. His assassination profoundly influenced the future of the United States, especially as the country was coming back together again following the Civil War. Testaments to his lasting legacy can be seen in many places, from the stone carving of him on Mount Rushmore to his image gracing the $5 bill. What if the President had survived his injury? Would he have had a different outcome utilizing current critical care treatment? Neurotrauma care in 1865 was not yet developed, and head wounds such as the one Lincoln sustained were almost always fatal. The medical attention he received is considered by historians and physicians today to be excellent for that time. We look at the evolution of neurotrauma care during the last 150 years in the US. Particular focus is paid to the advancement of care for penetrating brain injuries in modern trauma centers. PMID:26092530

  15. The Aerodynamic Characteristics of a Slotted Clark Y Wing as Affected by the Auxiliary Airfoil Position

    NASA Technical Reports Server (NTRS)

    Wenzinger, Carl J; Shortal, Joseph A

    1932-01-01

    Aerodynamic force tests on a slotted Clark Y wing were conducted in a vertical wind tunnel to determine the best position for a given auxiliary airfoil with respect to the main wing. A systematic series of 100 changes in location of the auxiliary airfoil were made to cover all the probable useful ranges of slot gap, slot width, and slot depth. The results of the investigation may be applied to the design of automatic or controlled slots on wings with geometric characteristics similar to the wing tested. The best positions of the auxiliary airfoil were covered by the range of the tests, and the position for desired aerodynamic characteristics may easily be obtained from charts prepared especially for the purpose.

    The pressure distribution data discussed in this report represents the results of part of an investigation conducted on the factors affecting the aerodynamic safety of airplanes. The present tests were made on semispan, circular-tipped Clark Y airfoil models mounted in the conventional manner on a separation plane. Pressure readings were made simultaneously at all test orifices at each of 20 angles of attack between -8 degrees and +90 degrees. The results of the tests on each wing arrangement are compared on the bases of maximum normal force coefficient, lateral stability at a low rate of roll, and relative longitudinal stability. Tabular data are also presented giving the center of pressure location of each wing.

  17. Clark Lake microbursts - On a lower limit to type III burst brightness temperatures

    NASA Technical Reports Server (NTRS)

    White, S. M.; Kundu, M. R.; Szabo, A.

    1987-01-01

    Further observations of solar microbursts by the Clark Lake radioheliograph are reported. The microbursts have properties consistent with weak type III bursts, with the implication that type III's can have brightness temperatures as low as 1 million K. The importance of this result is explored. A single model to explain the stronger type III bursts and the weaker microbursts is sought. It is shown that none of the models for stabilizing the strongest type III electron streams can explain the observed microbursts: these models have threshold levels of Langmuir waves which imply emission (due to spontaneous scattering off ions) with brightness temperatures in excess of those observed. It appears that either some vital physics is still missing from models for type III bursts, or that microbursts should have properties significantly different from those of type III bursts. In the latter case further observations should allow important tests of type III models.

  18. Luminescent sensing and imaging of oxygen: fierce competition to the Clark electrode.

    Wolfbeis, Otto S

    2015-08-01

    Luminescence-based sensing schemes for oxygen have experienced a fast growth and are in the process of replacing the Clark electrode in many fields. Unlike electrodes, sensing is not limited to point measurements via fiber optic microsensors, but includes additional features such as planar sensing, imaging, and intracellular assays using nanosized sensor particles. In this essay, I review and discuss the essentials of (i) common solid-state sensor approaches based on the use of luminescent indicator dyes and host polymers; (ii) fiber optic and planar sensing schemes; (iii) nanoparticle-based intracellular sensing; and (iv) common spectroscopies. Optical sensors are also capable of multiple simultaneous sensing (such as O2 and temperature). Sensors for O2 are produced nowadays in large quantities in industry. Fields of application include sensing of O2 in plant and animal physiology, in clinical chemistry, in marine sciences, in the chemical industry and in process biotechnology. PMID:26113255

  19. Anniversary of the discovery/isolation of the yeast centromere by Clarke and Carbon.

    2015-05-01

    The first centromere was isolated 35 years ago by Louise Clarke and John Carbon from budding yeast. They embarked on their journey with rudimentary molecular tools (by today's standards) and little knowledge of the structure of a chromosome, much less the nature of a centromere. Their discovery opened up a new field, as centromeres have now been isolated from fungi and numerous plants and animals, including mammals. Budding yeast and several other fungi have small centromeres with short, well-defined sequences, known as point centromeres, whereas regional centromeres span several kilobases up to megabases and do not seem to have DNA sequence specificity. Centromeres are at the heart of artificial chromosomes, and we have seen the birth of synthetic centromeres in budding and fission yeast and mammals. The diversity in centromeres throughout phylogeny belie conserved functions that are only beginning to be understood. PMID:25926702

    The Small Satellite Technology Initiative (SSTI) is a National Aeronautics and Space Administration (NASA) program to demonstrate smaller, high technology satellites constructed rapidly and less expensively. Under SSTI, NASA funded the development of ``Clark,'' a high technology demonstration satellite to provide 3-m resolution panchromatic and 15-m resolution multispectral images, as well as collect atmospheric constituent and cosmic x-ray data. The 690-lb. satellite, to be launched in early 1997, will be in a 476 km, circular, sun-synchronous polar orbit. This paper describes the program objectives, the technical characteristics of the sensors and satellite, image processing, archiving and distribution. Data archiving and distribution will be performed by NASA Stennis Space Center and by the EROS Data Center, Sioux Falls, South Dakota, USA.

    This year, 2013-2014, marks the 130th anniversary of the 8” Alvan Clark refracting telescope and observatory building at Albion College, an undergraduate college in Albion, MI. Completed in 1884, the observatory is an excellent example of a nineteenth century astronomical building; its telescope is still useable and other instruments (Fauth and Company sidereal clock, transit telescope, and chronograph) are in very good condition. The building has a long history, serving once as a barracks for World War I soldiers, and the telescope has helped to train the next generation of scientists, from Forest Ray Moulton (Class of 1894) to present-day students. Several times each year, the telescope is open to the public and to the campus community for public observing events, and during the anniversary year, several other activities are planned. I will describe the history of our observatory and its people and give an overview of the events planned for this year.

    2014-01-01

    Background The role for sentinel lymph node biopsy (SLNB) in patients with thin melanoma (≤1mm) remains controversial. We examined a large cohort of patients with thin melanoma to better define predictors of SLN positivity. Methods Between 1995-2011, 781 patients with thin primary melanoma and evaluable clinicopathologic data underwent SLNB at our institution. Predictors of SLN positivity were determined using univariate and multivariate regression analyses, and patients were risk-stratified using a classification and regression tree (CART) analysis. Results In the study cohort (n=781), 29 patients (3.7%) had nodal metastases. In the univariate analysis, mitotic rate (OR=8.11, p=0.005), Clark level (OR=4.04, p=0.003), and thickness (OR=3.33, p=0.011) were significantly associated with SLN positivity. In the multivariate analysis, MR (OR=7.01) and level IV-V (OR=3.45) remained significant predictors of SLN positivity. CART analysis initially stratified lesions by mitotic rate; non-mitogenic lesions (n=273) had a 0.7% SLN positivity rate versus 5.6% in mitogenic lesions (n=425). Mitogenic lesions were further stratified by Clark level; patients with level II-III had a 2.9% SLN positivity rate (n=205) versus 8.2% with level IV-V (n=220). With median follow up of 6.3 years, 5 SLN negative patients developed nodal recurrence and 4 SLN positive patients died of disease. Conclusion SLN positivity is low in patients with thin melanoma (3.7%) and exceedingly so in non-mitogenic lesions (0.7%). Appreciable rates of SLN positivity can be identified in patients with mitogenic lesions, particularly with concurrent level IV-V regardless of thickness. These factors may guide appropriate selection of patients with thin melanoma for SLNB. PMID:24121883

  4. Window of Opportunity: The Climatic Conditions of the Lewis and Clark Expedition of 1804 1806.

    Knapp, Paul A.

    2004-09-01

    Lewis and Clark's entry into to the American West in search of an inland Northwest Passage is considered among the greatest expeditions in American history. The Corps of Discovery were also lucky as their travels west of the 100th meridian occurred during a “window” of generally favorable climatic conditions. Use of reconstructed summer Palmer drought severity index (PDSI) values from 1700 1978 indicate that drought frequency at locations along the Lewis and Clark trail ranged from 4 to 12 yr and that the probability of encountering a drought either on the outbound or return trip approached 50% at some locations. Exact date comparisons of meteorological conditions during periods of extended encampment (i.e., 1 5 months) between 1804 06 with long-term records of nearby weather stations indicate that the Corps of Discovery avoided drought and traveled during a cooler and/or substantially wetter period than historical averages. Examination of reconstructed Southern Oscillation index (SOI) and Pacific decadal oscillation (PDO) values suggest wetter conditions prevailed in 1804 06 because of the co-occurrence of La Niña conditions during a cold PDO phase. Although the Corps of Discovery suffered hardships because of the wetter conditions, they avoided the more serious consequences of severe droughts that occurred in 1800 and 1808. Drought conditions along the semiarid and arid portions of the trail would have reduced forage yield for the game that were their principal source of food and increased their chances for starvation. Additionally, lower streamflow conditions along their principal navigation routes would have required greater effort and time to haul their supplies to the Continental Divide, perhaps delaying their expedition by a year.

  5. Patterns and Potential Drivers of a Seasonal Glacial Sediment Plume derived from Landsat CDR Data, Lake Clark, Alaska

    Lake Clark is large freshwater lake in Southcentral Alaska. Central to Lake Clark National Park and Preserve, Lake Clark is an important nursery lake for sockeye salmon (Oncorhynchus nerka) in the headwaters of Bristol Bay, Alaska, the most productive wild salmon fishery in the world. Lake Clark water clarity is seasonally influenced by a dynamic glacier fed sediment plume. We reconstructed lake-wide water clarity for Lake Clark using the Landsat TM and ETM+ Climate Data Record archive. Our study period consisted of May - October for 1985-2015. We found 151 (98 partial- and 53 whole-lake) Landsat scenes that captured the lake and/or sediment plume. Water clarity fluctuated on an annual basis with specific conditions common to certain months. Plume development and peak turbidity dates could be estimated for a number of years and mid-season gyres appear to represent wind-induced mixing of lake water. Our results showed short term (sub-decadal) trends in water clarity but little to no long term trend between 1991 and 2014. We did, however, detect interannual variation that exhibited a non-significant (r2 = 0.20) but positive correlation (r = 0.20) with regional mean summer air temperature and found the month of May exhibited a significant positive trend (r2 = 0.68, p-value = 0.02) in turbidity between 2000 and 2014. These results are important because reductions in water clarity within Alaska lake systems as a result of increased glacial runoff have been shown to reduce salmon production via reduced abundance of preferred prey items of juvenile salmon, such as zooplankton and macroinvertebrates.

    Genetic bottleneck effects can reduce genetic variation, persistence probability, and evolutionary potential of populations. Previous microsatellite analysis suggested a bottleneck associated with a common founding of sock-eye salmon Oncorhynchus nerka populations of Lake Clark, Alaska, about 100 to 400 generations ago. The common foundingevent occurred after the last glacial recession and resulted in reduced allelic diversity and strong divergence of Lake Clarksockeye salmon relative to neighboring Six Mile Lake and LakeIliamna populations. Here we used two additional genetic marker types (allozymes and mtDNA) to examine these patterns further. Allozyme and mtDNA results were congruent with the microsatellite data in suggesting a common founder event in LakeClark sockeye salmon and confirmed the divergence of Lake Clarkpopulations from neighboring Six Mile Lake and Lake Iliamna populations. The use of multiple marker types provided better understanding of the bottleneck in Lake Clark. For example, the Sucker Bay Lake population had an exceptionally severe reduction in allelic diversity at microsatellite loci, but not at mtDNA. This suggests that the reduced microsatellite variation in Sucker Bay Lake fish is due to consistently smaller effective population size than other Lake Clark populations, rather than a more acute or additional bottleneck since founding. Caution is urged in using reduced heterozygosity as a measure of genetic bottleneck effects because stochastic variance among loci resulted in an overall increase in allozyme heterozygosity within bottlenecked Lake Clark populations. However, heterozygosity excess, which assesses heterozygosity relative to allelic variation, detected genetic bottleneck effects in both allozyme and microsatellite loci.

    The abundance and distribution of bald eagles (Haliaeetus leucocephalus) on the lower Clark Fork River, Lake Pend Oreille, and the upper Pend Oreille River, Idaho, were documented during the winters of 1985--86 and 1986--87. Peak counts of bald eagles in weekly aerial censuses were higher in 1985--86 (274) and 1986--87 (429) than previously recorded in mid-winter surveys. Differences in eagle distribution within and between years were apparently responses to changes in prey availability. Eight bald eagles were captured and equipped with radio transmitters in the winter and spring of 1986. Residencies within the study area averaged 13.9 days in 1985--86 and 58.3 days for the four eagles that returned in 1986-87. The eagles exhibited considerable daily movement throughout the study area. After departing the area, one eagle was later sighted approximately 1185 km to the southwest in northern California. Eagle behavioral activity was recorded at time budget sessions at areas of heavy use. Perching in live trees was the most common behavior observed. 34 refs., 39 figs., 17 tabs.

    Autosomal dominant ataxias are a genetically heterogeneous group of disorders for which spinocerebellar ataxia (SCA) loci on chromosomes 6p, 12q, 14q and 16q have been reported. We have examined 170 individuals (56 of whom were affected) from a previously unreported ten-generation kindred with a dominant ataxia that is clinically and genetically distinct from those previously mapped. The family has two major branches which both descend from the paternal grandparents of President Abraham Lincoln. Among those examined, 56 individuals have a generally non-life threatening cerebellar ataxia. Disease onset varies from 10-68 years and anticipation is evident. We have mapped this gene, spinocerebellar ataxia type 5 (SCA5), to the centromeric region of chromosome 11. PMID:7874171

    How do astronomical methods make it possible to calculate dates and times for Vincent van Gogh's night-sky paintings? Why is there a blood-red sky in Edvard Munch's The Scream? On what dates did Ansel Adams create his moonrise photographs in Yosemite? How can the 18.6-year cycle of the lunar nodes and the Moon's declination on the night of August 29-30, 1857, explain a long-standing mystery about Abraham Lincoln's honesty in the murder case known as the almanac trial? Why is a bright star described in Act 1, Scene 1, of Hamlet? To answer questions like these, our Texas State group has published a series of articles over the last two decades, applying astronomy to art, history, and literature.

    The majority of work performed by the Lincoln Laboratory's Space Surveillance Group, at the request of NASA, to define the near-earth population of man-made debris is summarized. Electrooptical devices, each with a 1.2 deg FOV, were employed at the GEODSS facility in New Mexico. Details of the equipment calibration and alignment procedures are discussed, together with implementation of a synchronized time code for computer controlled videotaping of the imagery. Parallax and angular speed data served as bases for distinguishing between man-made debris and meteoroids. The best visibility was obtained in dawn and dusk twilight conditions at elevation ranges of 300-2000 km. Tables are provided of altitudinal density distribution of debris. It is noted that the program also yielded an extensive data base on meteoroid rates.

    A reconnaissance level geohydrologic study was made of 2,408 sq mi in Androscoggin, Cumberland, Franklin, Kennebec, Lincoln, Oxford, Sagadahoc and Somerset Counties in Maine. This area is included in Maps 10, 11, 16, 17, and 32 of the Sand and Gravel Aquifer Map Series published by the Maine Geological Survey. The significant sand and gravel aquifers, consist of glacial ice-contact and outwash deposits which occur primarily in the valleys of the major rivers and along their tributaries. Significant aquifers comprise almost 109 sq mi, but yields that exceed 50 gal/min are estimated to be available within only 21% of this area. Typically, the water table is within 20 ft of the land surface. Based on seismic data, the great known depth to bedrock is 340 ft. The regional groundwater quality has the following characteristics: It is slightly acidic to slightly basic; calcium and sodium are the most abundant cations; bicarbonate is the most abundant anion; and the water is soft. In some localities concentrations of iron and manganese are high enough to limit use of the water without treatment. Sixty-six sites, including 32 solid waste facilities and 18 salt-storage lots were identified as potential sources of groundwater contamination to the sand and gravel aquifers in the study area. 79 refs., 11 figs., 9 tabs.

    Benthic organisms in the upper Clark Fork River have recently been implicated as a dietary source of metals that may be a chronic problem for young-of-the-year rainbow trout (Oncorhynchus mykiss). In this present study, early life stage brown trout (Salmo trutta) and rainbow trout were exposed for 88 d to simulated Clark Fork River water and a diet of benthic invertebrates collected from the river. These exposures resulted in reduced growth and elevated levels of metals in the whole body of both species. Concentrations of As, Cd, Cu, and Pb increased in whole brown trout; in rainbow trout, As and Cd increased in whole fish, and As also increased in liver. Brown trout on the metals-contaminated diets exhibited constipation, gut impaction, increased cell membrane damage (lipid peroxidation), decreased digestive enzyme production (zymogen), and a sloughing of intestinal mucosal epithelial cells. Rainbow trout fed the contaminated diets exhibited constipation and reduced feeding activity. We believe that the reduced standing crop of trout in the Clark Fork River results partly from chronic effects of metals contamination in benthic invertebrates that are important as food for young-of-the-year fish.

    A Clark-type oxygen chip consisting of a polydimethylsiloxane (PDMS) reservoir containing an amino group-modified PDMS oxygen-permeable membrane (OPM) and a glass substrate containing a three-electrode detector has been constructed by using microfabrication techniques, and it is utilized for in situ measurement of the respiration activity of adhering cells. Use of the alginate sol electrolyte and the electroplating Ag/AgCl pseudo-reference electrode can effectively diminish the crosstalk between the electrochemical electrodes and supply a stable potential for the detection of dissolved oxygen, respectively. The Clark-type oxygen chips possess only 1.00% residual current, response time of 13.4s and good linearity with a correlation coefficient of 0.9933. The modification of amino groups for the OPM obviously facilitates the adhesion of HeLa cells onto the PDMS OPM surface and allows the cells to spread after 2h of incubation. The oxygen consumption of the cells in the cell-adhesion process increases with the adhesion time, and the increment of cellular oxygen consumption per minute reaches a maximum after 30 min of incubation. Moreover, the change in the respiration activity of adhering HeLa cells stimulated by the high concentration of glucose or propofol anaesthetic can be monitored in real time with the Clark-type oxygen chip.

    With the renewed interest in propellers as means of obtaining thrust and fuel efficiency in addition to the increased utilization of the computer, a significant amount of progress was made in the development of theoretical models to predict the performance of propeller systems. Inherent in the majority of the theoretical performance models to date is the need for airfoil data banks which provide lift, drag, and moment coefficient values as a function of Mach number, angle-of-attack, maximum thickness to chord ratio, and Reynolds number. Realizing the need for such data, a study was initiated to provide airfoil data banks for three commonly used airfoil families in propeller design and analysis. The families chosen consisted of the Clark-Y, NACA 16 series, and NACA 4 digit series airfoils. The various component of each computer code, the source of the data used to create the airfoil data bank, the limitations of each data bank, program listing, and a sample case with its associated input-output are described. Each airfoil data bank computer code was written to be used on the Amdahl Computer system, which is IBM compatible and uses Fortran.

  17. Montana's Clark Fork River Basin Task Force: A Vehicle for Integrated Water Resources Management?

    2010-11-01

    This article examines what is generally considered to be an unattainable goal in the western United States: integrated water resources management (IWRM). Specifically, we examine an organization that is quite unique in the West, Montana’s Clark Fork River Basin Task Force (Task Force), and we analyze its activities since its formation in 2001 to answer the question: are the activities and contributions of the Task Force working to promote a more strongly integrated approach to water resources management in Montana? After reviewing the concepts underlying IWRM, some of the issues that have been identified for achieving IWRM in the West, and the Montana system of water right allocation and issues it faces, we adapt Mitchell’s IWRM framework and apply it to the analysis of the Task Force’s activities in the context of IWRM. In evaluating the physical, interaction, and protocol/planning/policy components of IWRM, we find that the Task Force has been contributing to the evolution of Montana’s water resources management towards this framework, though several factors will likely continue to prevent its complete realization. The Task Force has been successful in this regard because of its unique nature and charge, and because of the authority and power given it by successive Montana legislatures. Also critical to the success of the organization is its ability to help translate into policy the outcomes of legal and quasi-judicial decisions that have impacted the state’s water resources management agency.

    Comprehensive study of the Morrowan brachiopod faunas of the Bird Spring Group at Arrow Canyon, Clark County, Nevada, is important because the section has been suggested as a stratotype for the base and top of the Pennsylvanian Subsystem and for the Atoka Series. Twenty-three species of brachiopods belonging to 17 genera occur in zone 20 at Arrow Canyon. Many of these also occur in described Morrowan faunas in Wyoming, Colorado, Utah, and New Mexico; but similarities with the Mid-Continent and Appalachian assemblages are less. However, no striking regional differences are evident, and it appears that the North American Morrowan fauna is more or less homogeneous. In contrast to the exotic South American and Arctic elements known from Atokan, Missourian, and Virgilian rocks at Arrow Canyon, no foreign taxa have been noted in zone 20. Microfacies and faunal association indicate four distinct brachiopod-bearing environments; (1) relatively deep water below turbulence with few brachiopods on a soft substrate; (2) somewhat shallower, more turbulent water with many species, of which only a few are represented by large populations, living on a more firm substrate; (3) environments just below the zone of turbulence in which many species of brachiopods are represented by substantial populations on a calcarenitic substrate; and (4) crinoidal bars in the zone of turbulence with a few species represented by relatively few individuals.

    Luhmann, Janet C.

    The recent letter from Clark Chapman in the April 3, 1990, issue of Eos (p. 376), concerning planetary research supported by the National Aeronautics and Space Administration struck a resonance that warrants airing in view of the analogous situation that prevails in Space Physics research. The situation for Research and Analysis (R&A) and Data Analysis programs in Space Physics has a more complicated history in view of the fact that only recently has the Space Physics discipline been given its own division within NASA (with thanks to the particular efforts of Lennard Fisk and Stanley Shawhan). For many years, Space Physics research was spread among several divisions at NASA headquarters. Now, magnetospheric, cosmic ray and heliospheric, upper atmospheric and ionospheric, and solar physics have been gathered together under the umbrella of the Space Physics division. It was hoped that this highly desired and much heralded merger would give these related scientific subdisciplines greater coherence and greater visibility, and hence make them better able to compete for needed resources. However, even in the years before the Challenger disaster, it became clear that the issue is no longer simply one of competition between the research divisions within NASA. Across all disciplines, the struggle for survival by research groups outside of NASA centers has become crippling.

    Fluvial deposits of tailings and other mining-related waste in selected riparian habitats of the Upper Clark Fork River basin (Montana) have resulted in metals enriched soils. The significance of metals exposure to selected wildlife species was evaluated by measuring tissue residues of metals (arsenic, cadmium, copper, lead, zinc) in key dietary species, including dominant grasses (tufted hair grass and redtop), willows, alfalfa, barley, invertebrates (grasshoppers, spiders, and beetles), and deer mice. Average metals concentrations in grasses, invertebrates, and deer mice collected from tailings-affected sites were elevated relative to reference to reference levels. Soil-tissue bioconcentration factors for grasses and invertebrates were generally lower than expected based on the range of values in the literature, indicating the reduced bioavailability of metals from mining waste. In general, metals concentrations in willows, alfalfa, and barley were not elevated above reference levels. Using these data and plausible assumptions for other exposure parameters for white-tailed deer, red fox, and American kestrel, metals intake was estimated for soil and diet ingestion pathways. Comparisons of exposure estimates with toxicity reference values indicated that the elevated concentrations of metals in key food web species do not pose a significant risk to wildlife.

    Among the problems facing Northern Ireland after its foundation in 1920, one of the most daunting was the prevalence of tuberculosis, a chronic communicable disease with highest mortality among young women and men in the prime of life. Over a quarter of a century, legislative changes tardily responded, and in spite of, or because of its magnitude, Brice Clarke (1895–1975) devoted himself to the challenge. After decorated service in the Great War of 1914–19 he returned to finish his medical studies in Queen's University Belfast and held hospital appointments until he became Chief Tuberculosis Officer for Belfast and soon afterwards Director of Tuberculosis Services in Northern Ireland. For twenty years he was an enthusiastic proponent of collapse therapy, and even before the new chemotherapy hastened the natural decline in the tuberculosis epidemic he trumpeted the value of properly equipped chest clinics and generously funded welfare schemes. His garden at Hillsborough could not contain him in retirement; he set off on a slow boat to Japan in 1962, and returned to pen biographical sketches of famous consumptives until his death in 1975 at the age of 80.

    A 46-day exposure examined the effects of metals contamination in a live natural freshwater diet on rainbow trout fry. Survival, growth, and whole-body tissue metals were compared among groups of trout fed live planktonic invertebrates (primarily Daphnia pulex) collected from the Clark Fork River (CFR), Montana and trout fed live laboratory-reared D. pulex. Metals of interest in the diets were As, Cu, Cd, Pb, and Zn. In addition to dietary exposure, treatments included simultaneous exposure to a mixture of waterborne metals (Cu, Cd, Pb, and Zn) at sublethal concentrations. Trout showed no statistically significant effects on survival or growth from mean CFR invertebrate metal concentrations of 20.1 mg As/kg dwt, 60.7 mg Cu/kg dwt, 4.0 mg Cd/kg dwt, 4.9 mg Pb/kg dwt, and 249 mg Zn/kg dwt. Waterborne and dietary Cd and Pb appeared to result in increased tissue concentrations of these metals, while only dietary As resulted in increased tissue As. Neither dietary nor waterborne copper or zinc had a substantial effect on tissue levels of these metals. Results were consistent, in terms of the lack of statistically significant growth and survival effects, with those of previous in-house studies exposing rainbow trout to metals-enriched Artemia sp. (brine shrimp) diets.

    The potential for storm events to mobilize metals in floodplain tailings and alter surface water quality was assessed at four location in the Upper Clark Fork River during the spring and summer of 1994. Ten storm events of varying intensity and duration were captured. For each event, temporal variations in the concentration of arsenic, cadmium, copper, lead, and zinc were characterized over the 15-hour period following the initiation of rainfall. Metal concentrations for all storm events were invariant over time with the exception of copper, which displayed a transient increase in concentration of short duration and limited intensity for two of the ten events. The ability to discern the subtle changes in copper concentration is attributed to the use of clean sampling techniques and highly sensitive and accurate analytical techniques (ICP-MS). Results indicate that rainfall-induced increases in copper concentration will occur for only a small percentage of rainfall events. These transient events are short-lived (typically less than four hours), do not exceed applicable water quality criteria, and, based on toxicity testing, would not adversely affect fish.

    The Horse Spring Formation of Miocene age in Clark County, Nevada, contains as much as 0.5% Li in individual samples. Rock sequences which average 0.1% Li range from 3 m thick near Gold Butte (south of Mesquite, Nev.) to as much as 40 m thick near Lava Butte (east of Las Vegas, Nev.) about 75 km to the west. The lithium-bearing beds are light colored to white and contain hectorite in a dolomite, magnesite, or calcite matrix. Varied amounts of gypsum, halite, celestite, clinoptilolite, quartz, feldspar, biolite and colemanite are also present locally. Hectorite is the only lithium mineral recognized to date. The lithium-rich rocks contain low concentrations of most other minor elements except that boron and strontium are enriched. Rarely, barium, arsenic, and zinc are present in anomalously large amounts. The lithium-enriched part of the Horse Spring Formation was formed from a series of volcanic ashes which were deposited in a playa. Relict volcanic ash is recognizable in thin sections as remnant glass shards and vitroclastic textures. Most of the original glass has been altered to clay minerals, carbonate minerals, or zeolites, presumably through interaction with highly saline pore waters. Abundant evidence of spring activity suggests that thermal waters played a part in releasing the lithium from volcanic materials. ?? 1978.

  5. Stratigraphic evidence for multiple drainings of glacial Lake Missoula along the Clark Fork River, Montana, USA

    2006-09-01

    Glacial Lake Missoula, a source of Channeled Scabland flood waters, inundated valleys of northwest Montana to altitudes of ˜ 1265 m and to depths of >600 m, as evidenced by shorelines and silty lacustrine deposits. This study describes previously unrecognized catastrophic lake-drainage deposits that lie stratigraphically beneath the glacial-lake silts. The unconsolidated gravelly flood alluvium contains imbricated boulder-sized clasts, cross-stratified gravel with slip-face heights of 2-> 35 m, and 70- to 100-m-high gravel bars which all indicate a high-energy, high-volume alluvial environment. Gravel bars and high scablands were formed by catastrophic draining of one or possibly more early, high lake stands (1200-1265 m). Most glacial-lake silt, such as the Ninemile section, was deposited stratigraphically above the earlier deposits, represents a lower lake stand(s) (1050-1150 m), and was not deposited in lake(s) responsible for the highest discharge events. The glaciolacustrine silt-covered benches are incised by relict networks of valleys formed during the drainage of the last glacial lake. Significant erosion associated with the last lake draining was confined to the inner Clark Fork River canyon.

    This progress report summarizes the results of a miscible cyclic CO{sub 2} project conducted at West Mallalieu Field Unit (WMU) Lincoln County, MS by J.P. Oil Company, Inc. Lafayette, LA. Information is presented regarding the verification of the mechanical integrity of the present candidate well, WMU 17-2B, to the exclusion of nearby more desirable wells from a reservoir standpoint. Engineering summaries of both the injection and flow back phases of the cyclic process are presented. The results indicate that the target volume of 63 MMCF of CO{sub 2} was injected into the candidate well during the month of August 2000 and a combined 73 MMCF of CO{sub 2} and formation gas were recovered during September, October, and November 2000. The fact that all of the injected CO{sub 2} was recovered is encouraging; however, only negligible volumes of liquid were produced with the gas. A number of different factors are explored in this report to explain the lack of economic success. These are divided into several groupings and include: Reservoir Factors, Process Factors, Mechanical Factors, and Special Circumstances Factors. It is impossible to understand precisely the one or combination of interrelated factors responsible for the failure of the experiment but I feel that the original reservoir quality concerns for the subject well WMU 17-2B were not surmountable. Based on the inferences made as to possible failure mechanisms, two future test candidates were selected, WMU 17-10 and 17-14. These lie a significant distance south of the WMU Pilot area and each have a much thicker and higher quality reservoir section than does WMU 17-2B. Both of these wells were productive on pumping units in the not too distant past. This was primary production not influenced by the distant CO{sub 2} injection. These wells are currently completed within somewhat isolated reservoir channels in the Lower Tuscaloosa ''A'' and ''B-2'' Sands that overlie the much more continuous and much larger Lower

    Pruet Production Co. and the Center for Sedimentary Basin Studies at the University of Alabama, in cooperation with Texas A&M University, Mississippi State University, University of Mississippi, and Wayne Stafford and Associates are undertaking a focused, comprehensive, integrated and multidisciplinary study of Upper Jurassic Smackover carbonates (Class II Reservoir), involving reservoir characterization and 3-D modeling and an integrated field demonstration project at Womack Hill Oil Field Unit, Choctaw and Clarke Counties, Alabama, Eastern Gulf Coastal Plain. The principal objectives of the project are: increasing the productivity and profitability of the Womack Hill Field Unit, thereby extending the economic life of this Class II Reservoir and transferring effectively and in a timely manner the knowledge gained and technology developed from this project to producers who are operating other domestic fields with Class II Reservoirs. The principal research efforts for Year 3 of the project have been recovery technology analysis and recovery technology evaluation. The research focus has primarily been on well test analysis, 3-D reservoir simulation, microbial core experiments, and the decision to acquire new seismic data for the Womack Hill Field area. Although Geoscientific Reservoir Characterization and 3-D Geologic Modeling have been completed and Petrophysical and Engineering Characterization and Microbial Characterization are essentially on schedule, a no-cost extension until September 30, 2003, has been granted by DOE so that new seismic data for the Womack Hill Field can be acquired and interpreted to assist in the determination as to whether Phase II of the project should be implemented.

    Laurel Clark Earth Camp is designed to inspire teachers and students to study their world through field experiences, remote sensing investigations, and hands on exploration, all of which lend context to scientific inquiry. In three different programs (for middle school students, for high school students, and for teachers) participants are challenged to understand Earth processes from the perspectives of both on-the ground inspection and from examination of satellite images, and use those multiple perspectives to determine best practices on both a societal and individual scale. Earth Camp is a field-based program that takes place both in the “natural” and built environment. Middle School Earth Camp introduces students to a variety of environmental science, engineering, technology, and societal approaches to sustainability. High School Earth Camp explores ecology and water resources from southern Arizona to eastern Utah, including a 5 day rafting trip. In both camps, students compare environmental change observed through repeat photography on the ground to changes observed from space. Students are encouraged to utilize their camp experience in considering their future course of study, career objectives, and lifestyle choices. During Earth Camp for Educators, teachers participate in a series of weekend workshops to explore relevant environmental science practices, including water quality testing, biodiversity surveys, water and light audits, and remote sensing. Teachers engage students, both in school and after school, in scientific investigations with this broad based set of tools. Earth Stories from Space is a website that will assist in developing skills and comfort in analyzing change over time and space using remotely sensed images. Through this three-year NASA funded program, participants will appreciate the importance of scale and perspective in understanding Earth systems and become inspired to make choices that protect the environment.

    Few vertebrates run on water. The largest animals to accomplish this feat are western and Clark's grebes (Aechmophorus occidentalis and Aechmophorus clarkii). These birds use water running to secure a mate during a display called rushing. Grebes weigh an order of magnitude more than the next largest water runners, basilisk lizards (Basilicus basiliscus), and therefore face a greater challenge to support their body weight. How do these birds produce the hydrodynamic forces necessary to overcome gravity and sustain rushing? We present the first quantitative study of water running by grebes. High-speed video recordings elucidate the hindlimb movements of grebes rushing in the wild. We complement these findings with laboratory experiments using physical models and a preserved grebe foot to estimate how slapping the water surface contributes to weight support. Our results indicate that grebes use three novel tactics to successfully run on water. First, rushing grebes use exceptionally high stride rates, reaching 10 Hz. Second, grebe foot size and high water impact speed allow grebes to generate up to 30-55% of the required weight support through water slap alone. Finally, flattened foot bones reduce downward drag, permitting grebes to retract each foot from the water laterally. Together, these mechanisms outline a water-running strategy qualitatively different from that of the only previously studied water runner, the basilisk lizard. The hydrodynamic specializations of rushing grebes could inform the design of biomimetic appendages. Furthermore, the mechanisms underlying this impressive display demonstrate that evolution can dramatically alter performance under sexual selection. PMID:25911734

  11. Sediment Transport and Deposition Resulting from a Dam-Removal Sediment Pulse: Milltown Dam, Clark Fork River, MT

    Wilcox, A. C.

    2010-12-01

    The removal of Milltown Dam in 2008 from the Clark Fork River, Montana, USA, lowered base level at the dam site by 9 m and triggered erosion of nearly 600,000 metric tons of predominantly fine reservoir sediment. Bedload and bed-material sampling, repeat topographic surveys, sediment transport modeling, geochemical fingerprinting of downstream sediments, and Lidar analysis have all been applied to study the upstream and downstream effects of the dam removal. In the years since dam breaching, successive years with similar peak flows (3-year recurrence interval) were followed by a third year with below-average runoff. Nearly all of the documented reservoir erosion occurred in the first year, when sand and silt was eroded and transported downstream. In subsequent years, minimal reservoir erosion occurred, in part as a result of active management to prevent further reservoir erosion, but coarse material eroded from the reservoir has dispersed downstream. Upstream responses in this system have been strongly mediated by Superfund remediation activities in Milltown Reservoir, in which over two million metric tons of contaminated sediments have been mechanically excavated. Downstream aggradation has been limited in the main channel but was initially substantial in bars and side channels of a multi-thread reach 21 to 25 km downstream of the dam site, suggesting that channel change has been influenced far more by the antecedent depositional environment than by proximity to the source of the sediment pulse. Comparison of observed erosion with pre-removal modeling shows that reservoir erosion exceeded model predictions by two orders of magnitude in the unconfined Clark Fork arm of the reservoir. In addition, fine reservoir sediments predicted to move exclusively in suspension traveled as bedload at lower transport stages. The resulting fine sediment deposition in substrate interstices, on bars, and in side channels of the gravel- and cobble-bed Clark Fork River is the most

    Heller, Andrew Roland

    The Fort Clark State Historic Site (32ME2) is a well known site on the upper Missouri River, North Dakota. The site was the location of two Euroamerican trading posts and a large Mandan-Arikara earthlodge village. In 2004, Dr. Kenneth L. Kvamme and Dr. Tommy Hailey surveyed the site using aerial color and thermal infrared imagery collected from a powered parachute. Individual images were stitched together into large image mosaics and registered to Wood's 1993 interpretive map of the site using Adobe Photoshop. The analysis of those image mosaics resulted in the identification of more than 1,500 archaeological features, including as many as 124 earthlodges.

    The brachiopod genus Verneuilia Hall and Clarke, 1893, is recognized for the first time in North America, where it is represented by a new species described here. V. langenstrasseni. This occurrence extends not only the geographic range of the genus, but also the lower age and stratigraphic limit into the Eifelian (early Middle Devonian). Previously, the oldest known species was the type, V. cheiropteryx d'Archiac and de Verneuil, 1842, from the Givetian (late Middle Devonian) of Germany. Internal structures of V. langenstrasseni n.sp. are similar to those of genera in the ambocoeliid subfamily Rhynchospiriferinae, providing the first good evidence of a systematic relationship. -Authors

    Clarke, DeNora and Vuoskoski's valuable review paper [2] raises the proposition that passive musical listening experiences can increase 'dispositional empathy' in individuals and consequently lead to increased positive feeling towards other cultural groups. The challenge of integrating relevant ideas and evidence from neuroscience, philosophy, psychology, sociology and community music is met convincingly, alongside the presentation of empirical data and a new model of empathic music listening. The resulting discussion brings social, motor and emotional aspects of musical behavior to the forefront and sparks a number of ideas and questions.

  16. A method of estimating the aerodynamic effects of ordinary and split flaps of airfoils similar to the Clark Y

    An empirical method is given for estimating the aerodynamic effect of ordinary and split flaps on airfoils similar to the Clark Y. The method is based on a series of charts that have been derived from an analysis of existing wind-tunnel data. Factors are included by which such variables as flap location, flap span, wing aspect ratio, and wing taper may be taken into account. A series of comparisons indicate that the method would be suitable for use in making preliminary performance calculations and in structural design.

    2003-12-01

    Clark County, Nevada is located in the southern portion of the Basin and Range Province. As such, it has undergone tremendous extensional forces that produced numerous north-trending ridges and basins. Little is known regarding the crustal structure of the southern Basin and Range. Extension along the Las Vegas Valley Shear Zone (LVVSZ) has produced a northwest-trending corridor of particular interest that may channel seismic energy into the Las Vegas basin. Potential sources include energy produced by earthquakes as well as nuclear testing, should the Nevada Test Site (NTS) become active in the future. Previous studies include a crustal velocity model in the form of a fence diagram by Prodehl (1979) based on Legacy data, seismic refraction experiments performed when the NTS was active. Legacy data were collected on seismometers placed at intervals greater than or equal to 500 m. Seismic sources included chemical blasts and nuclear test shots. To examine whether structures along the corridor would cause seismic energy to dissipate or to transmit into the basin, in September 2002 we utilized 400 seismic instruments to record the Watusi chemical blast at the Nevada Test Site. The profile extended from Ann Road and I-95 northwest to the town of Indian Springs, where the station spacing was 125 m. The blast was located 65 km away from the first station and was expected to have the energy equivalent to 40,000 tons of TNT. However, most of the energy was lost into the air. In addition, falling debris produced diffractions in the data. We picked first arrivals and analyzed these data with forward modeling utilizing MacRay ray-tracing software, integrating these with Prodehl's model to produce an updated, higher resolution crustal velocity model. The model indicates velocities of the upper to lower crust, into the Moho, with average velocities of approximately 6 km/s. Further studies will include integrating data from the Seismic Investigation of the Las Vegas Valley

    Test of 4' x 20' Clark-Y airfoil model in Full-Scale Tunnel (FST). On June 26, 1929, Elton W. Miller wrote to George W. Lewis proposing the construction of a model of the full-scale tunnel. 'The excellent energy ratio obtained in the new wind tunnel of the California Institute of Technology suggests that before proceeding with our full scale tunnel design, we ought to investigate the effect on energy ratio of such factors as: 1. small included angle for the exit cone; 2. carefully designed return passages of circular section as far as possible, without sudden changes in cross sections; 3. tightness of walls. It is believed that much useful information can be obtained by building a model of about 1/16 scale, that is, having a closed throat of 2 ft. by 4 ft. The outside dimensions would be about 12 ft. by 25 ft. in plan and the height 4 ft. Two propellers will be required about 28 in. in diameter, each to be driven by direct current motor at a maximum speed of 4500 R.P.M. Provision can be made for altering the length of certain portions, particularly the exit cone, and possibly for the application of boundary layer control in order to effect satisfactory air flow. This model can be constructed in a comparatively short time, using 2 by 4 framing with matched sheathing inside, and where circular sections are desired they can be obtained by nailing sheet metal to wooden ribs, which can be cut on the band saw. It is estimated that three months will be required for the construction and testing of such a model and that the cost will be approximately three thousand dollars, one thousand dollars of which will be for the motors. No suitable location appears to exist in any of our present buildings, and it may be necessary to build it outside and cover it with a roof.' George Lewis responded immediately (June 27) granting the authority to proceed. He urged Langley to expedite construction and to employ extra carpenters if necessary. Funds for the model came from the FST

    The Thompson Falls Dam inundated approximately 347 acres of wildlife habitat that likely included conifer forests, deciduous bottoms, mixed conifer-deciduous forests and grassland/hay meadows. Additionally, at least one island, and several gravel bars were inundated when the river was transformed into a reservoir. The loss of riparian and riverine habitat adversely affected the diverse wildlife community inhabiting the lower Clark Fork River area. Quantitative loss estimates were determined for selected target species based on best available information. The loss estimates were based on inundation of the habitat capable of supporting the target species. Whenever possible, loss estimates bounds were developed by determining ranges of impacts based on density estimates and/or acreage loss estimates. Of the twelve target species or species groups, nine were assessed as having net negative impacts. 86 refs., 2 figs., 5 tabs.

  1. The diffusion of the distance Entomology Master's Degree Program at the University of Nebraska Lincoln: A descriptive case study

    NASA Astrophysics Data System (ADS)

    Hubbell, Jody M.

    This study explored three selected phases of Rogers' (1995) Diffusion of Innovations Theory to examine the diffusion process of the distance Entomology Master's Degree program at the University of Nebraska, Lincoln. A qualitative descriptive case study approach incorporated semi-structured interviews with individuals involved in one or more of the three stages: Development, Implementation, and Institutionalization. Documents and archival evidence were used to triangulate findings. This research analyzed descriptions of the program as it moved from the Development, to the Implementation, and finally, the Institutionalization stages of diffusion. Each respective stage was examined through open and axial coding. Process coding identified themes common to two or more diffusion stages, and explored the evolution of themes from one diffusion stage to the next. At a time of significant budget constraints, many departments were faced with the possibility of merger or dissolution. The Entomology Master's Degree Program evolved from being an entrepreneurial means to prevent departmental dissolution to eventually being viewed as a model for the development of similar programs across this university and other institutions of higher education. During this evolution, the program was reinvented to meet the broader needs of industry and a global student market. One finding not consistent with Rogers' model was that smaller, rather than larger, departmental size contributed to the success of the program. Within this small department, faculty members were able to share their experiences and knowledge with each other on a regular basis, which promoted greater acceptance of the distance program. How quality and rigor may be defined and measured was a key issue in each respective stage. In this specific case, quality and rigor was initially a comparison of on-campus and distance course content and then moved to program-based assessment and measures of student outcomes such as job

    How do astronomical methods make it possible to calculate dates and times for Vincent van Gogh's night-sky paintings? Why is there a blood-red sky in Edvard Munch's The Scream? How can the 18.6-year cycle of the lunar nodes and the Moon's declination on the night of August 29-30, 1857, explain a long-standing mystery about Abraham Lincoln's honesty in the murder case known as the almanac trial? Why is a bright star described in Act 1, Scene 1, of Hamlet? There is a long tradition of astronomical methods employed to analyze works of art, to understand historical events, and to elucidate passages in literature. Both Edmond Halley and George Biddell Airy calculated lunar phases and tide tables in attempts to determine the landing beach where Julius Caesar invaded Britain in 55 B.C. Henry Norris Russell computed configurations of Jupiter and Saturn to determine a date for a 14th-century celestial event mentioned in Chaucer's Troilus and Criseyde. In this tradition, our Texas State group has published a series of articles in Sky & Telescope over the last two decades, applying astronomy to art, history, and literature. Don Osterbrock worked with us 3 years ago when my students and I calculated dates for moonrise photographs taken by Ansel Adams in Yosemite National Park. The peaks of the Sierra Nevada crest in Yosemite are more than 125 miles from Lick Observatory, but the mountains can become visible from Lick on clear winter days and were photographed from there on early infrared-sensitive plates during the 1920s and 1930s. As we tested our topographic software by identifying the peaks that appear in the Lick plates, it was a pleasure to come to know Don, a former director of Lick Observatory and the person in whose honor this talk is dedicated.

    In birds where males and females are similar in size and plumage, sex determination by alternative means is necessary. Discriminant function analysis based on external morphometrics was used to distinguish males from females in two closely related species: Western Grebe (Aechmophorus occidentalis) and Clark's Grebe (A. clarkii). Additionally, discriminant function analysis was used to evaluate morphometric divergence between Western and Clark's grebe adults and eggs. Aechmophorus grebe adults (n = 576) and eggs (n = 130) were sampled across 29 lakes and reservoirs throughout California, USA, and adult sex was determined using molecular analysis. Both Western and Clark's grebes exhibited considerable sexual size dimorphism. Males averaged 6–26% larger than females among seven morphological measurements, with the greatest sexual size dimorphism occurring for bill morphometrics. Discriminant functions based on bill length, bill depth, and short tarsus length correctly assigned sex to 98% of Western Grebes, and a function based on bill length and bill depth correctly assigned sex to 99% of Clark's Grebes. Further, a simplified discriminant function based only on bill depth correctly assigned sex to 96% of Western Grebes and 98% of Clark's Grebes. In contrast, external morphometrics were not suitable for differentiating between Western and Clark's grebe adults or their eggs, with correct classification rates of discriminant functions of only 60%, 63%, and 61% for adult males, adult females, and eggs, respectively. Our results indicate little divergence in external morphology between species of Aechmophorus grebes, and instead separation is much greater between males and females.

    Clark County, Nevada had a 52% increase in newly diagnosed HIV infections in young people age 13-24 with 83% of the new diagnoses in this age group being men who have sex with men (MSM). HIV testing and counseling is critical for HIV prevention, care and treatment, yet young people are the least likely to seek HIV testing. The purpose of this study was to identify barriers and facilitators to HIV testing experienced by young MSM in Clark County, Nevada. We conducted a qualitative focus group discussion to identify barriers and facilitators to HIV testing among eleven young MSM in March, 2015. The primary barrier to HIV testing identified by the group was a lack of awareness or knowledge about testing for HIV. Other barriers within the person included: fear of results, fear of rejection, and fear of disclosure. Barriers identified within the environment included: access issues, stigma, and unfriendly test environments for young people. In addition to increasing awareness, intervention to increase HIV testing among MSM young people should incorporate access to testing in environments where the adolescents are comfortable and which reduces stigma. HIV testing sites should be convenient, accessible and young person/gay friendly. PMID:26925893

    Migratory bull trout (Salvelinus confluentus) historically spawned in tributaries of the Clark Fork River, Montana and inhabited Lake Pend Oreille as subadult and adult fish. However, in 1952 Cabinet Gorge Dam was constructed without fish passage facilities disrupting the connectivity of this system. Since the construction of this dam, bull trout populations in upstream tributaries have been in decline. Each year adult bull trout return to the base of Cabinet Gorge Dam when most migratory bull trout begin their spawning migration. However, the origin of these fish is uncertain. We used eight microsatellite loci to compare bull trout collected at the base of Cabinet Gorge Dam to fish sampled from both above and further downstream from the dam. Our data indicate that Cabinet Gorge bull trout are most likely individuals that hatched in above-dam tributaries, reared in Lake Pend Oreille, and could not return to their natal tributaries to spawn. This suggests that the risk of outbreeding depression associated with passing adults over dams in the Clark Fork system is minimal compared to the potential genetic and demographic benefits to populations located above the dams.

    The Permian San Andres Formation of late Leonardian-early Guadalupian age is a significant hydrocarbon producer and crops out over a large area in south-central New Mexico. However, since its definition in 1909, the age and depositional environment of this unit have been questioned. In 1971 in Pecos County, Vincent Kelly divided the unit into three members: Rio Bonito, Bonney Canyon, and Fourmile Draw. The lowest member, although named for the Rio Bonito, has a type section designated at Sunset along U.S. Highway 70/380. Two miles east of Sunset, near Riverside, on the Rio Bonito, the Rio Bonito Member is exposed in a long series of roadcuts. Petrographic investigation of these rocks reveals an alternating sequence of high to low-energy intertidal to subtidal facies marked by oolitic and fossiliferous dolocalcarenite interbedded with dolomitic mudstone. The unit has been recrystallized and stylolites are abundant, as is dolomite and nodular mosaic anhydrite. These alternating units contain a faunal assemblage that is marked by red algae, foraminifera, bryozoa, crinoids, pelecypods, brachiopods, and cephalopods. Burrow fillings and fecal pellets are also abundant. The authors suggest that these units mark an extensive carbonate flat containing shoals and lagoons with open-marine and intertidal channels.

  11. Direct observation of heavy metal-mineral association from the Clark Fork River Superfund Complex: Implications for metal transport and bioavailability

    Two sets of samples from riverbeds and adjacent floodplains, separated by 80 river kilometers, were collected from the Clark Fork River Superfund Complex, Montana, (the largest Superfund site in the United States), and studied primarily with transmission electron microscopy (TEM) with several supporting techniques to determine heavy metal-mineral association. Seven of the eight samples studied were strongly influenced by material that once resided in mining and smelting dumps and impoundments; this material was transported downstream sometime during the last century and a half from the Butte/Anaconda areas. The eighth sample was from a deeper floodplain level and dates to premining days. The TEM observations afford a direct look, down to the nanometer level, at secondary mineral formation as a result of the breakdown of sulfides and silicates in the acid environment of this massive mine-drainage system. In the shallow, oxic floodplain sediments, heavy metals of concern in this system (As, Cu, Pb, and Zn) are taken up by the formation of sulfates (particularly Pb in jarosite), as well as hydrous metal oxides (As, Cu, Pb, and Zn in and on ferrihydrite, and a possibly new vernadite-like mineral). The oxides are long-lived in these systems, as they were also found in the anoxic riverbeds. Metals are also taken up by the formation of sulfides in sulfate-reducing environments as observed in the formation of nanoclusters of chalcopyrite and sphalerite. In all samples, clays make up between 5 and 20% of the sediment and carry significant amounts of Cu and Zn. The hydrous oxides, secondary sulfides, and clays provide several routes for metal transport downstream over long distances. Besides the potential bioavailability of heavy metals exchanged on and off the hydrous metal oxides and clays, nanometer-sized sulfides may also be highly reactive in the presence of biologic systems.

  12. Mercury Contributions from Flint Creek and other Tributaries to the Upper Clark Fork River in Northwestern Montana

    2013-12-01

    Methylmercury contamination in biota is a major factor diminishing the environmental quality of the Upper Clark Fork River (CFR), e.g. by triggering human consumption limits of fish. The CFR is subject to one of the largest Superfund cleanup projects in the US, but remediation and restoration is currently focused exclusively on other mining-related contaminants (As, Cu, Zn, Pb, Cd), which may be counterproductive with respect to the bio-availability of mercury, for example by creation of wetlands along mercury-contaminated reaches of the river. The identification and elimination of Hg sources is an essential step toward reducing the methylmercury exposure in the biota of the CFR watershed because a strong correlation exists between total mercury levels in river sediment and methylmercury levels in aquatic life. We analyzed duplicate samples from the top sediment layer of the main stem and significant tributaries to the Clark Fork River along a 240 km reach between Butte, MT and downstream of the Missoula Valley. Mercury concentrations were 1.3 × 1.6 (mean × SD, n = 35) in the main stem. Concentrations in tributaries varied widely (0.02 to 85 mg/kg) and seemed only loosely related to the number of historic precious metal mines in the watershed. In the upper reach of the CFR, elevated Hg levels are likely caused by residual contaminated sediments in the flood plain. Levels tend to decrease downstream until Drummond, MT, where Flint Creek contributes a significant amount of mercury, causing Hg levels in the main stem CFR to increase from 0.7 to 4 mg/kg. Levels continue to decrease downstream. Flint Creek is the single largest contributor of Hg to the CFR. Detailed sampling of the main stem Flint Creek and tributaries (26 sites) showed extremely high levels in two tributaries (22 to 85 mg/kg) where historic milling operations were located. Elimination of these point sources may be accomplished comparatively economically and may significantly reduce mercury levels in

    In 1803, President Thomas Jefferson set fourth a military expedition led by Captains M. Lewis and W. Clark (Lewis and Clark Expedition) on an exploration that would become an everlasting part of US national history and pride. Looking back at the events of this exploration, there are many similarities to the experiences future human space explorers will face as we look to colonize the Moon and travel to Mars and beyond (NASA Vision for Space Exploration, 2004): The Lewis and Clark Expedition lasted almost three years and involved a crew of 43 men traveling up the Missouri River to explore the unknown lands and a possible water route to the Pacific Ocean; The Expedition took place far away from customary comfortable environments known to European settlers in the early 18th century; The Expedition involved a remotely confined high-perceived risk environment with high levels of uncertainty providing stresses and every day challenges for the crew; Supplies brought on the mission were limited (mainly a mass/weight issue rather than cost), therefore the discovery and use of environmental resources (In-Situ Resource Utilization approach, including info-resources to mitigate uncertainty) was necessary for crew survival. The environments astronauts will encounter in space and on the Moon and Mars due to high risk and uncertainty will be in many aspects similar to what Lewis and Clark's crew experienced, as environments will be hostile and unforgiving if problems arise and aren't resolved quickly. The analysis provided in this research paper is relevant because the Lewis and Clark Expedition needed to move extensively and with minimal supplies. Polar remote settings, which were analyzed extensively, were different from this expedition due to the fact that these missions did not encompass extensive movement of crew facilities and supplies and were more like space missions orbiting the Earth. Using past space station results of performance on orbit in correlation with a

The team arrived at the Skid Strip at Cape Canaveral Air Station with First Lady Hillary Rodham Clinton to view the launch of Space Shuttle mission STS-93. Liftoff is scheduled for 12:36 a.m. EDT July 20. Much attention has been generated over the launch due to Commander Eileen M. Collins, the first woman to serve as commander of a Shuttle mission. The primary payload of the five-day mission is the Chandra X-ray Observatory, which will allow scientists from around the world to study some of the most distant, powerful and dynamic objects in the universe. The new telescope is 20 to 50 times more sensitive than any previous X-ray telescope and is expected to unlock the secrets of supernovae, quasars and black holes.

    In their critical review, Clarke, DeNora and Vuoskoski [3, this issue] integrate and make sense of a diverse range of theory and evidence to argue that music has the capacity to facilitate empathy and aid cultural understanding. The invitation to comment on this paper arrived in my email in-box at a time when Europe was witnessing one of the largest movements of people in modern times and when thousands of refugees were dying in the attempt to cross the Mediterranean. For a short while at least, empathy, or the lack thereof, became a socio-political lever, galvanizing European citizens to demonstrate their willingness to give asylum to refugees (#refugeeswelcome), and shaping domestic and European immigration policies. In this context, it would be hard to refute the importance of understanding empathy, albeit through its musical incarnation.

    Micrometeorological data were collected at Ash Meadows and Corn Creek Springs, Nye and Clark Counties, Nevada, from October 1, 1986 through September 30, 1987. The data include accumulated measurements recorded hourly or every 30 minutes, at each site, for the following climatic variables: air temperature, wind speed, relative humidity, precipitation, solar radiation, net radiation, and soil-heat flux. Periodic sampling of sensible-heat flux and latent-heat flux were also recorded using 5-minute intervals of accumulated data. Evapotranspiration was calculated by both the eddy-correlation method and the Penman combination method. The data collected and the computer programs used to process the data are available separately on three magnetic diskettes in card-image format. (USGS)

    A phase transition is taking place today. The amount of data generated by genome resequencing technologies is so large that in some cases it is now less expensive to repeat the experiment than to store the information generated by the experiment. In the next few years it is quite possible that millions of Americans will have been genotyped. The question then arises of how to make the best use of this information and jointly estimate the haplotypes of all these individuals. The premise of the paper is that long shared genomic regions (or tracts) are unlikely unless the haplotypes are identical by descent (IBD), in contrast to short shared tracts which may be identical by state (IBS). Here we estimate for populations, using the US as a model, what sample size of genotyped individuals would be necessary to have sufficiently long shared haplotype regions (tracts) that are identical by descent (IBD), at a statistically significant level. These tracts can then be used as input for a Clark-like phasing method to obtain a complete phasing solution of the sample. We estimate in this paper that for a population like the US and about 1% of the people genotyped (approximately 2 million), tracts of about 200 SNPs long are shared between pairs of individuals IBD with high probability which assures the Clark method phasing success. We show on simulated data that the algorithm will get an almost perfect solution if the number of individuals being SNP arrayed is large enough and the correctness of the algorithm grows with the number of individuals being genotyped.

    of this past arsenical pesticide use is not known in the region. Based on estimates from other areas (D'Angelo et al., 1996), cumulate application over the period of arsenical pesticide use may have been as much as 22.4 g/m2 of arsenic and 100 g/m2 of lead in orchard areas. In minimally disturbed orchard soils, arsenic and lead are largely retained in the top few centimeters of the soil horizon; intra-soil redistribution of these metals occurs but appears to be limited (Veneman et al. 1983; Peryea, 1998). Surface concentrations of arsenic and lead in undisturbed orchard soils where arsenical pesticides were used commonly exceed 20 mg/kg As and 100 mg/kg Pb (Veneman et al., 1983; Jones and Hatch, 1937). The digital data set of orchard locations was used to aid assessment of the likely occurrence and distribution of arsenical pesticide residues in surface soils. Most areas of orchard cultivation were sited in areas overlying carbonate bedrock in the Valley and Ridge province. This data set needed to be created since there was no reliable and complete land cover data set identifying areas under orchard cultivation during the time period of extensive use of arsenical pesticides in the study area as of the time of the study. The spatial database of orchard areas was compiled using twenty-seven USGS 7.5 minute series topographical maps covering the study area of Clarke and Frederick Counties, Virginia, and Berkeley and Jefferson Counties, West Virginia. These maps were published between 1943 and 1972 at 1:24,000 scale, with the oldest topographic map available from the US Geological Survey map archive for each area being chosen, going back only as far as the 1920s when use of arsenical pesticides started. Orchard areas on the topographic maps were traced in order to aid in the digitization of the sites. The topographic maps were then scanned and geographically referenced using ERDAS Imagine version 8.7, a raster editing program, turning them into rectifi

    Research on the fate and transport of endocrine-disrupting compounds and other organic wastewater compounds released into the environment and their potential presence in drinking water is in its infancy. Studies conducted during the last decade in Lincoln, Nebraska, and Berlin, Germany, indicate that removal of less polar compounds probably can be obtained through bank filtration, ground-water enrichment, and additional drinking-water and wastewater treatment processes. Polar compounds, such as atrazine and some metabolites, occur in drinking water obtained from contaminated surface water or ground water, but at concentrations generally lower than those occurring in wastewater and surface water. The results of the studies also suggest that concentrations of nonpolar estrogenic compounds decrease during drinking-water pretreatment processes such as bank filtration and ground-water enrichment.

    Pruet Production Co. and the Center for Sedimentary Basin Studies at the University of Alabama, in cooperation with Texas A&M University, Mississippi State University, University of Mississippi, and Wayne Stafford and Associates proposed a three-phase, focused, comprehensive, integrated and multidisciplinary study of Upper Jurassic Smackover carbonates (Class II Reservoir), involving reservoir characterization and 3-D modeling (Phase I) and a field demonstration project (Phases II and III) at Womack Hill Field Unit, Choctaw and Clarke Counties, Alabama, eastern Gulf Coastal Plain. Phase I of the project has been completed. The principal objectives of the project are: increasing the productivity and profitability of the Womack Hill Field Unit, thereby extending the economic life of this Class II Reservoir and transferring effectively and in a timely manner the knowledge gained and technology developed from this project to producers who are operating other domestic fields with Class II Reservoirs. The major tasks of the project included reservoir characterization, recovery technology analysis, recovery technology evaluation, and the decision to implement a demonstration project. Reservoir characterization consisted of geoscientific reservoir characterization, petrophysical and engineering property characterization, microbial characterization, and integration of the characterization data. Recovery technology analysis included 3-D geologic modeling, reservoir simulation, and microbial core experiments. Recovery technology evaluation consisted of acquiring and evaluating new high quality 2-D seismic data, evaluating the existing pressure maintenance project in the Womack Hill Field Unit, and evaluating the concept of an immobilized enzyme technology project for the Womack Hill Field Unit. The decision to implement a demonstration project essentially resulted in the decision on whether to conduct an infill drilling project in Womack Hill Field. Reservoir performance

  17. Nature's complex flume - Using a diagnostic state-and-transition framework to understand post-restoration channel adjustment of the Clark Fork River, Montana

    2016-02-01

    There is an imperfect symmetry between the patterns of channel evolution observed during laboratory flume experiments and those which materialize in rivers exposed to ambient environmental conditions that produce hydrogeomorphic fluxes which are more complex, contingent, and unpredictable. One strategy to improve our understanding of short- to medium-term channel evolution is to study landscapes that have undergone significant disturbance and have had their biogeomorphic templates reset to a known condition - in effect, creating a flume in nature. This study adopts a diagnostic state-and-transition framework to narrate and document baseline hypotheses for the potential evolutionary trajectories Clark Fork River, near Milltown, Montana. Following dam removal and remediation, a 5-km stretch of the Clark Fork River and its adjoining floodplain were reconstructed. Since flow was introduced to the newly constructed channel in December 2010, complex evolutionary trajectories have been observed on the Clark Fork's mainstem, its secondary channels, and floodplain. Focusing particularly on the river's secondary channels, this paper develops a typology of channel states that have been observed and demonstrates that multiple adjustment trajectories have materialized, sometimes within the same channel. A diagnostic state-and-transition framework offers a parsimonious strategy to quantitatively or qualitatively anticipate the influence of water, sediment, and ecological fluxes on channel evolution at the basin, reach, or segment scale. It provides environmental agencies with a robust method to devise spatially explicit scenario-based management plans for rivers in a variety of geomorphic settings.

    Concentrations of heavy metals in sediments and soils deposited along the floodplain of the Clark Fork River, within the boundaries of the Grant-Kohrs Ranch National Historic Site, have exceeded those typically found in uncontaminated soils. Upstream mining activities along the Clark Fork River in the Deer Lodge Valley, Montana, have produced substantial quantities of mine waste which have been deposited throughout the watershed. Releases and re-releases of these contaminated substances continue to occur, and appear to be preventing the germination and establishment of critical riparian plant species and depressing soil microbe activity. Slickens, bare spots devoid of all vegetation, occur frequently in the floodplain along the Clark Fork River. This research investigates the toxicity of slicken soils using a series of earthworm (Eisenia foetida andrei) survival and behavior tests. In dilution tests, earthworm survival was reduced significantly in as little as 12.5% slicken soil. Results from earthworm behavior tests currently being conducted using non-lethal slicken soil dilutions will also be presented.

  19. Alaska: Glaciers of Kenai Fjords National Park and Katmai and Lake Clark National Parks and Preserve

    NASA Technical Reports Server (NTRS)

    There are hundreds of glaciers in Kenai Fjords National Park (KEFJ) and Katmai National Park and Preserve (KATM) covering over 2276 sq km of park land (circa 2000). There are two primary glacierized areas in KEFJ -- the Harding Icefield and the Grewingk-Yalik Glacier Complex, and three primary glacierized areas in KATM - the Mt. Douglas area, the Kukak Volcano to Mt. Katmai area and the Mt. Martin area. Most glaciers in these parks terminate on land, though a few terminate in lakes. Only KEFJ has tidewater glaciers, which terminate in the ocean. Glacier mapping and analysis of the change in glacier extent has been accomplished on a decadal scale using satellite imagery, primarily Landsat data from the 1970s, 1980s, and from 2000. Landsat Multispectral Scanner (MSS), Thematic Mapper (TM) and Enhanced Thematic Mapper Plus (ETM+) imagery was used to map glacier extent on a park-wide basis. Classification of glacier ice using image processing software, along with extensive manual editing, was employed to create Geographic Information System (GIS) outlines of the glacier extent for each park. Many glaciers that originate in KEFJ but terminate outside the park boundaries were also mapped. Results of the analysis show that there has been a reduction in the amount of glacier ice cover in the two parks over the study period. Our measurements show a reduction of approximately 21 sq km, or -1.5% (from 1986 to 2000), and 76 sq km, or -7.7% (from 1986/87 to 2000), in KEFJ and KATM, respectively. This work represents the first comprehensive study of glaciers of KATM. Issues that complicate the mapping of glacier extent include: debris-cover (moraine and volcanic ash), shadows, clouds, fresh snow, lingering snow from the previous season, and differences in spatial resolution between the MSS and TM or ETM+ sensors. Similar glacier mapping efforts in western Canada estimate mapping errors of 3-4%. Measurements were also collected from a suite of glaciers in KEFJ and KATM detailing

    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

    H-alpha line profiles of 13 Be starts (mv d6.9) were observed using 45 cm Cassegrain telescope at the Arthur C Clarke Institute, Sri Lanka during the period of August 2005 to March 2006. High resolution spectra of these Be stars were obtained using 1200 lines/mm reflective grating in first order with resolution R=λ/Δλ=76800 and linear spectral dispersion 0.31 Å per pixel at 6563 Å in order to find out line parameters such as equivalent width, full width at half-maxima, V/R ratios etc. A study of the correlations between different pairs of parameters was obtained and compared with previous analysis to see the behavior of circumstellar disk. We found a good correlation (0.8) between FWHM and v sin i and strong correlation (0.96) between the Ip/Ic and the equivalent width. The drastic changes of the V/R ratio in profiles HR5941 and HR6712 imply the circumstellar disk is more likely an elliptical shape and undergoes slow apsidal motion. The inclination angles (i) were estimated for each star using the theoretical vsin i values and assuming star rotates in 0.8Vc and are matched with the structure of the line profiles.

  2. Investigation of Hyporheic Microbial Biofilms as Indicators of Heavy Metal Toxicity in the Clark Fork Basin, Montana

    Water-saturated sediments that underlie a stream channel contain microbial biofilms that are often responsible for the majority of the metabolic activity in river and stream ecosystems. Metal contamination from mining effluent can modify the biofilm community structure, diversity, and activity. Developing a mechanistic understanding of the biofilm response to metal contamination could provide a useful bioindicator of metal toxicity due to the ease of standard biofilm sampling, environmental ubiquity of biofilms and the rapid response of biofilms to environmental perturbation and metal toxicity. Here we present data on the structure of the biofilm community (e.g., microbial population composition and diversity) and trace metal concentrations in water, bed sediment and biota (benthic insects) across 15 sites in the Clark Fork Basin. Sample sites were selected across a historically-monitored metal pollution gradient at shallow riffles with bed sediment predominantly composed of pebbles, cobbles, and sand. Bed-sediment samples (for biofilm analysis) were obtained from the top 20 centimeters of the hyporheic zone and sieved using sterile sieves to obtain homogeneous sediment samples with particle sizes ranging from 1.70 to 2.36 millimeters. Linear discriminant analysis and effect size statistical methods were used to integrate the metals concentration data (for water and benthic-insects samples) with the microbial community analysis to identify microbial biomarkers of metal toxicity. The development of rapid microbial biomarker tools could provide reproducible and quantitative insights into the effectiveness of remediation activities on metal toxicity and advances in the field of environmental biomonitoring.

    The use of engineered plants as biosensors has made elegant strides in the past decades, providing keen insights into the health of plants in general and particularly in the nature and cellular location of stress responses. However, most of the analytical procedures involve laboratory examination of the biosensor plants. With the advent of the green fluorescence protein (GFP) as a biosensor molecule, it became at least theoretically possible for analyses of gene expression to occur telemetrically, with the gene expression information of the plant delivered to the investigator over large distances simply as properly processed fluorescence images. Spaceflight and other extraterrestrial environments provide unique challenges to plant life, challenges that often require changes at the gene expression level to accommodate adaptation and survival. Having previously deployed transgenic plant biosensors to evaluate responses to orbital spaceflight, we wished to develop the plants and especially the imaging devices required to conduct such experiments robotically, without operator intervention, within extraterrestrial environments. This requires the development of an autonomous and remotely operated plant GFP imaging system and concomitant development of the communications infrastructure to manage dataflow from the imaging device. Here we report the results of deploying a prototype GFP imaging system within the Arthur Clarke Mars Greenhouse (ACMG) an autonomously operated greenhouse located within the Haughton Mars Project in the Canadian High Arctic. Results both demonstrate the applicability of the fundamental GFP biosensor technology and highlight the difficulties in collecting and managing telemetric data from challenging deployment environments.

    Precipitation, potential evapotranspiration, and actual evapotranspiration often are used to characterize the hydroclimate of a region. Quantification of these parameters in mountainous terrains is difficult because limited access often hampers the collection of representative ground data. To fulfill a need to characterize ecological zones in the Spring Mountains and Sheep Range of southern Nevada, spatially and temporally explicit estimates of these hydroclimatic parameters are determined from remote-sensing and model-based methodologies. Parameter-elevation Regressions on Independent Slopes Model (PRISM) precipitation estimates for this area ranges from about 100 millimeters (mm) in the low elevations of the study area (700 meters [m]) to more than 700 mm in the high elevations of the Spring Mountains (> 2,800 m). The PRISM model underestimates precipitation by 7–15 percent based on a comparison with four high‑elevation precipitation gages having more than 20 years of record. Precipitation at 3,000-m elevation is 50 percent greater in the Spring Mountains than in the Sheep Range. The lesser amount of precipitation in the Sheep Range is attributed to partial moisture depletion by the Spring Mountains of eastward-moving, cool-season (October–April) storms. Cool-season storms account for 66–76 percent of annual precipitation. Potential evapotranspiration estimates by the Basin Characterization Model range from about 700 mm in the high elevations of the Spring Mountains to 1,600 mm in the low elevations of the study area. The model realistically simulates lower potential evapotranspiration on northeast-to-northwest facing slopes compared to adjacent southeast-to-southwest facing slopes. Actual evapotranspiration, estimated using a Moderate Resolution Imaging Spectroradiometer based water-balance model, ranges from about 100 to 600 mm. The magnitude and spatial variation of simulated, actual evapotranspiration was validated by comparison to PRISM precipitation

    Exotic species can threaten native ecosystems and reduce services that ecosystems provide to humans. Early detection of incipient populations of exotic species is a key step in containing exotics before explosive population growth and corresponding impacts occur. We report the results of the first three years of an exotic plant early detection and treatment program conducted along more than 3,000 km of transportation corridors within an area >1.5 million ha in the Mojave Desert, USA. Incipient populations of 43 exotic plant species were mapped using global positioning and geographic information systems. Brassica tournefortii (Sahara mustard) infested the most soil types (47% of 256) surveyed in the study area, while Nicotiana glauca (tree tobacco) and others currently occupy less than 5% of soil types. Malcolmia africana (African mustard) was disproportionately detected on gypsum soils, occurring on 59% of gypsum soil types compared to 27% of all surveyed soils. Gypsum soils constitute unique rare plant habitat in this region, and by conventional wisdom were not previously considered prone to invasion. While this program has provided an initial assessment of the landscape-scale distribution of exotic species along transportation corridors, evaluations of both the survey methods and the effectiveness of treating incipient populations are needed. An exotic plant information system most useful to resource mangers will likely include integrating planning oriented coarse-scale surveys, more detailed monitoring of targeted locations, and research on species life histories, community invasibility, and treatment effectiveness.

    Simulation of the measured discharge hydrographs for the verification storms utilizing TC and R obtained from the estimation equations yielded good results. The error in peak discharge for 21 of the 29 verification storms was less than 25 percent, and the error in time-to-peak discharge for 18 of the 29 verification storms also was less than 25 percent. Therefore, applying the estimation equations to determine TC and R for design-storm simulation may result in reliable design hydrographs, as long as the physical characteristics of the watersheds under consideration are within the range of those characteristics for the watersheds in this study [area: 0.02-2.3 mi2, main-channel length: 0.17-3.4 miles, main-channel slope: 10.5-229 feet per mile, and insignificant percentage of impervious cover].

    The Mound Spring quadrangle, the southwestern-most 7.5' quadrangle of the area of the Las Vegas 1:100,000-scale quadrangle, is entirely within the Pahrump Valley, spanning the Nevada/California State line. New geologic mapping of the predominantly Quaternary materials is combined with new studies of gravity and geochronology in this quadrangle. Eleven predominantly fine-grained units are delineated, including playa sediment, dune sand, and deposits associated with several cycles of past groundwater discharge and distal fan sedimentation. These units are intercalated with 5 predominantly coarse-grained alluvial-fan and wash gravel units mainly derived from the Spring Mountains. The gravel units are distinguished on the basis of soil development and associated surficial characteristics. Thermoluminescence and U-series geochronology constrain most of the units to the Holocene and late and middle Pleistocene. Deposits of late Pleistocene groundwater discharge in the northeast part of the quadrangle are associated with a down-to-the-southwest fault zone that is expressed by surface fault scarps and a steep gravity gradient. The gravity field also defines a northwest-trending uplift along the State line, in which the oldest sediments are poorly exposed. About 2 km to the northeast a prominent southwest-facing erosional escarpment is formed by resistant beds in middle Pleistocene fine-grained sediments that dip northeast away from the uplift. These sediments include cycles of groundwater discharge that were probably caused by upwelling of southwesterly groundwater flow that encountered the horst.

    Four different genes that cause spinocerebellar ataxia (SCA1, SCA2, Machado Joseph`s Disease (MJD)/SCA3 and SCA4) have been mapped to chromosomes 6p, 12q, 14q, and 16q, respectively. We have examined and collected 170 individuals (56 affected) from a previously unreported 10 generation kindred (the Lincoln Family) with a dominant ataxia that is clinically and genetically distinct from those previously mapped. The family has two major branches from Indiana and Kentucky. Of historical interest is that both branches descend from the paternal grandparents of President Abraham Lincoln. While the ataxia in this kindred is disabling, the most striking clinical distinction from SCA1, SCA2 and MJD/SCA3 is that it is generally not life threatening. This clinical difference is explained by the absence of bulbar paralysis and lower motor neuron degeneration that causes respiratory muscle weakness. We have mapped the gene, SCA5, using microsatellite markers spaced at 20-40 cM intervals throughout the genome. After 75 markers, the first to demonstrate a lod score greater than 3.0 was D11S871 (Zmax=5.05). Four additional markers from the centromeric region of chromosome 11 also gave lod scores greater than 3. The highest lod scores were 12.3 for both D11S905 ({theta}=0.056) and D11S913 ({theta}=0.030). Multipoint linkage and haplotype analyses indicate the most likely location for SCA5 is within the 7 cM interval between GATA2A01 and D11S913. A statistical analysis of the age of onset of parent-offspring pairs within the family supports (p<0.0002) the presence of anticipation. Several dramatic examples of anticipation have been observed in which grandmothers have onsets 10-20 years later in life than their daughters who have onsets 10-20 years later than their children. Interestingly, all four of the juvenile onset cases are maternally inherited, suggesting a maternal bias in anticipation for SCA5 rather than a paternal bias as seen with SCA1.

    bounded on the east by normal faults at the base of Frenchman Mountain, on the west by a possible normal fault that coincides with a zone of fault scarps, on the north by vertical or strike-slip displacement along the Las Vegas shear zone, and on the northwest by a bedrock high that underlies the area between Tule Springs and Corn Creek Springs. The shallow bedrock surface (as much as 1,000 feet deep) underlies the west side of the valley from La Madre Mountain to the McCullough Range. Some of the fault scarps in the valley fill coincide with possible bedrock faults, which suggests a tectonic origin for some of the faulting of valley-fill deposits; however, the area of fault scarps on the west side of the valley also coincides with a rapid lateral change from incompressible bedrock to more compressible valley-fill deposits. Thus, both differential compaction and tectonic movement may be responsible for faulting of valley-fill deposits.

    The Woodland 7.5' quadrangle is situated in the Puget-Willamette Lowland approximately 50 km north of Portland, Oregon (fig. 1). 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, the Cascade Range has been the locus of an 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 Woodland quadrangle lies at the northern edge of the Portland Basin, a roughly 2000-km2 topographic and structural depression that is the northernmost of several sediment-filled structural basins, which collectively constitute the Willamette Valley segment of the Puget-Willamette Lowland (Beeson and others, 1989; Swanson and others, 1993; Yeats and others, 1996). The Portland Basin is approximately 70 km long and 30 km wide; its long dimension is oriented northwest. Its northern boundary coincides, in part, with the lower Lewis River, which flows westward through the center of the quadrangle. The Lewis drains a large area in the southern Washington Cascade Range, including the southern flank of Mount St. Helens approximately 25 km upstream from the quadrangle, and joins the Columbia River about 6 km south of Woodland (fig. 1). Northwest of Woodland, the Columbia River exits the broad floodplain of the Portland Basin and flows northward through a relatively narrow bedrock valley at an elevation near sea level. The flanks of the Portland Basin consist of Eocene through Miocene volcanic and sedimentary rocks that rise to elevations exceeding 2000 ft (610 m). Seismic-reflection profiles (L.M.

    Two recent dam removals on tributaries to the Columbia River in the northwestern United States present contrasting examples of how dam removal methods, reservoir contents, and geomorphic settings influence system responses. The 2008 removal of Milltown Dam, from the Clark Fork River (CFR), Montana, and the 2011 removal of Condit Dam from the White Salmon River (WSR), Washington (Table 1), represent two of the largest dam removals to date. The Milltown Dam removal was notable because the dam stored millions of cubic meters of contaminated mine tailings, a portion of which were excavated as part of Superfund remediation but a portion of which flowed downstream after the removal. On the CFR, post-breach high flows in 2008 produced reservoir erosion and downstream deposition in bed interstices, along bars, and on the floodplain, but above-average (3-15 year recurrence interval) floods since then have remobilized this material and have, to a large extent, erased signs of downstream sedimentation. The Condit Dam removal entailed dynamiting of a 4m by 5.5m hole at the base of the dam, which produced rapid and dramatic draining of fine reservoir sediments within hours of the blast. Downstream of Condit Dam, the initial hyperconcentrated flows and sediment pulse draped the WSR with fine sediment, filled pools, and, in an unconfined reach influenced by the Columbia River's backwater, caused meters of aggradation and new bar formation. In the confined, bedrock-dominated reach downstream of the Condit site, pool-riffle structure has started to reemerge as of summer 2012 and the finest bed materials have been evacuated from the main channel, although sediment storage in pools and eddies persists. Whereas post-breach geomorphic responses on the CFR have been largely driven by hydrology, the post-breach evolution of the WSR has been predominantly influenced by antecedent geomorphic conditions (slope, confinement, and Columbia River backwater). On both the CFR and WSR, the pace of

    General methods of theoretical analysis of airplane spinning characteristics have been available for some time. Some of these methods of analysis might be used by designers to predict the spinning characteristics of proposed airplane designs if the necessary aerodynamic data were known. The present investigation, to determine the spinning characteristics of wings, is planned to include variations in airfoil sections, plan forms, and tip shapes of monoplane wings and variations in stagger, gap, and decalage for biplane cellules. The first series of tests, made on a rectangular Clark Y monoplane wing, are reported in reference 1. That report also gives an analysis of the data for predicting the probable effects of various important parameters on the spin for normal airplanes using such a wing. The present report is the second of the series. It gives the aerodynamic characteristics of a rectangular Clark Y biplane cellule in spinning attitudes and includes a discussion of the data, using the method of analysis given in reference 1.

    With near-complete replacement of Arctic multi-year ice (MYI) by first-year ice (FYI) predicted to occur within this century, it remains uncertain how the loss of MYI will impact the abundance and distribution of sea ice associated algae. In this study we compare the chlorophyll a (chl a) concentrations and physical properties of MYI and FYI from the Lincoln Sea during 3 spring seasons (2010-2012). Cores were analysed for texture, salinity, and chl a. We identified annual growth layers for 7 of 11 MYI cores and found no significant differences in chl a concentration between the bottom first-year-ice portions of MYI, upper old-ice portions of MYI, and FYI cores. Overall, the maximum chl a concentrations were observed at the bottom of young FYI. However, there were no significant differences in chl a concentrations between MYI and FYI. This suggests little or no change in algal biomass with a shift from MYI to FYI and that the spatial extent and regional variability of refrozen leads and younger FYI will likely be key factors governing future changes in Arctic sea ice algal biomass. Bottom-integrated chl a concentrations showed negative logistic relationships with snow depth and bulk (snow plus ice) integrated extinction coefficients; indicating a strong influence of snow cover in controlling bottom ice algal biomass. The maximum bottom MYI chl a concentration was observed in a hummock, representing the thickest ice with lowest snow depth of this study. Hence, in this and other studies MYI chl a biomass may be under-estimated due to an under-representation of thick MYI (e.g., hummocks), which typically have a relatively thin snowpack allowing for increased light transmission. Therefore, we suggest the on-going loss of MYI in the Arctic Ocean may have a larger impact on ice-associated production than generally assumed. PMID:25901605

  20. What Factors Are Associated with Positive Effects of Dog Ownership in Families with Children with Autism Spectrum Disorder? The Development of the Lincoln Autism Pet Dog Impact Scale

    Scientific literature exploring the value of assistance dogs to children with autism spectrum disorder (ASD) is rapidly emerging. However, there is comparably less literature reporting the effects of pet (as opposed to assistance) dogs to these children. In particular, there are no known validated scales which assess how children may alter their behaviours in the presence of the dog, to evaluate the efficacy of pet dogs to these families. Additionally, given the highly individualised nature of ASD it is likely that some children and families gain more benefits from dog ownership than others, yet no research has reported the effect of individual differences. This pilot study reports the development of a 28-item scale based on the perceived impact of a pet dog on a child with autism by parents (Lincoln Autism Pet Dog Impact Scale—LAPDIS). The scale is comprised of three mathematically derived factors: Adaptability, Social Skills and Conflict Management. We assessed how individual differences (aspects) may be associated with scores on these three factors. Family Aspects and Dog Aspects were not significantly associated with ratings on the three factors, but Child Aspects (including: contact with horses, child age, disability level and language abilities) were related to impact of the dog on all factors. Training Aspects were related to scores on Social Skills (formal training with children with ASD and dogs and attendance at PAWS workshops run by Dogs for Good). These results suggest that individual differences associated with the child and the training approach may be important considerations for a positive impact from dog ownership on families with children with ASD. Differences in family features and the dog may not be so important, but may be worthy of further investigations given the early stage of development in this field. PMID:26894820
