Hydrogeology and Water Quality of the Clinton Street-Ballpark Aquifer near Johnson City, New York  

USGS Publications Warehouse

The Clinton Street-Ballpark aquifer, in the Susquehanna River valley in southern Broome County, N.Y., supplies drinking water to the Village of Johnson City near Binghamton. The hydrogeology and water quality of the aquifer were studied in 1994-95 to identify the source area of 1,1,1-trichloroethane, which was detected at the Johnson City Camden Street wellfield in 1991. The aquifer is generally 100 to 150 ft thick and consists primarily of ice-contact deposits of silty sand and gravel that are overlain by outwash deposits of sand and gravel. These two types of deposits are separated by lacustrine silt and clay of variable thickness into an upper and a lower layer of the aquifer. The coarse deposits form a single aquifer in areas where the lacustrine deposits are absent. Synoptic water-level surveys indicated that ground water moves from upgradient areas flanking the aquifer boundaries toward two major pumping centers?the Anitec wellfield in Binghamton and the Camden Street wellfield in Johnson City. Areas contributing recharge to municipal and industrial wells in the aquifer were delineated by a previously developed groundwater- flow model. The residence time of ground water within the area contributing recharge to Johnson City well no. 2 in the Camden Street wellfield was estimated to be less than 6 years. 1,1,1-Trichloroethane, trichloroethene, and their metabolites were detected in ground water at several locations in and near Johnson City. Relatively high concentrations of 1,1,1-trichloroethane were found in ground water about 3,000 ft north of the Camden Street wellfield. The suspected source is an area bordered on the south by Field Street, on the north by Harry L. Drive, on the east by New York State Route 201, and on the west by Marie Street. A trichloroethene metabolite, cis-1,2-dichloroethene, appears to be migrating westward from U.S. Air Force Plant 59 toward the Camden Street well-field, 1,000 ft southwest of the plant, although this compound has not been detected in water pumped by municipal wells, possibly because it has become diluted by ground water from other locations within the contributing area to the wells.

Site handbook: data acquisition system information, Johnson Controls, Inc. building, Salt Lake City, Utah  

SciTech Connect

The Johnson Controls, Inc. new 16,000 square foot branch office in Salt Lake City, Utah, is one project in the DOE Passive Solar Commercial Buildings Program. The primary passive solar features are the daylighting system that includes light shelves on the south windows and an insulated clerestory glazing system, direct gain heating, and evaporative cooling. Construction of the building was completed in February 1982. Data were collected by Johnson Controls for one year with a JC/85 Energy Management System. Virtually continuous hourly data were recorded on an Aeolian Kinetics PDL-24 between December 1983 and December 1984. These hourly data were used by ESG, Inc. in their BLAST simulations of the building. A report detailing the building energy performance using the hourly data was prepared by Architectural Energy Corporation. This book contains information about the building, the data acquisition system, and the data acquisition process. The hourly data for the Johnson Controls branch office are stored on computer files at the American Institute of Architects Foundation in Washington, DC.

Northeast Tennessee Educators' Perception of STEM Education Implementation  

NASA Astrophysics Data System (ADS)

A quantitative nonexperimental survey study was developed to investigate Northeast Tennessee K-8 educators' perceptions of STEM education. This study was an examination of current perceptions of STEM education. Perceived need, current implementation practices, access to STEM resources, definition of STEM, and the current condition of STEM in Northeast Tennessee were also examined. The participating school districts are located in the Northeast Region of Tennessee: Bristol City Schools, Hamblen County Schools, Johnson City Schools, Johnson County Schools, Kingsport City Schools, Sullivan County Schools, and Washington County Schools. Educational professionals including both administrators and teachers in the elementary and/or middle school setting were surveyed. The closed and open form survey consisted of 20 research items grouped by 5 core research questions. Quantitative data were analyzed using single sample t tests. A 4 point Likert scale was used to measure responses with a 2.5 point of neutrality rating. The open-ended question was summarized and recorded for frequency. Research indicated that Northeast Tennessee K-8 educators perceive a need for STEM education to a significant extent. However, many do not feel prepared for implementation. Lack of professional development opportunities and STEM assets were reported as areas of need. Teachers reported implementation of inquiry-based, problem solving activities in their classrooms. The majority of participants reported that the current condition of STEM education in Northeast Tennessee is not meeting the needs of 21st century learners. Challenges facing STEM instruction include: funding designated for STEM is too low, professional development for STEM teacher is insufficient, and STEM Education in K-8 is lacking or inadequate.

An initial analysis of LANDSAT-4 Thematic Mapper data for the discrimination of agricultural, forested wetlands, and urban land cover. [Poinsett County, Arkansas; and Reelfoot Lake and Union City, Tennessee  

NASA Technical Reports Server (NTRS)

The capabilities of TM data for discriminating land covers within three particular cultural and ecological realms was assessed. The agricultural investigation in Poinsett County, Arkansas illustrates that TM data can successfully be used to discriminate a variety of crop cover types within the study area. The single-date TM classification produced results that were significantly better than those developed from multitemporal MSS data. For the Reelfoot Lake area of Tennessee TM data, processed using unsupervised signature development techniques, produced a detailed classification of forested wetlands with excellent accuracy. Even in a small city of approximately 15,000 people (Union City, Tennessee). TM data can successfully be used to spectrally distinguish specific urban classes. Furthermore, the principal components analysis evaluation of the data shows that through photointerpretation, it is possible to distinguish individual buildings and roof responses with the TM.

Optical Johnson noise thermometry  

NASA Technical Reports Server (NTRS)

A concept is being explored that an optical analog of the electrical Johnson noise may be used to measure temperature independently of emissivity. The concept is that a laser beam may be modulated on reflection from a hot surface by interaction of the laser photons with the thermally agitated conduction electrons or the lattice phonons, thereby adding noise to the reflected laser beam. If the reflectance noise can be detected and quantified in a background of other noise in the optical and signal processing systems, the reflectance noise may provide a noncontact measurement of the absolute surface temperature and may be independent of the surface's emissivity.

The Jane Johnson Collection  

NSDL National Science Digital Library

Back in the middle of the 18th century, what was a young parent to do when it came to providing a meaningful and lasting education for their son or daughter? It would be a few decades before Rousseau's Emilie, and a bit longer for John Dewey to make the scene, so parents had to be a bit more creative. One particularly enterprising soul was Jane Johnson, who decided to create a set of materials designed to instruct her son, George William Johnson, in a variety of subjects. Several hundred years later, the good folks at Indiana University's Lilly Library decided to digitize these rather remarkable teaching aids so that the web-browsing public might be able to look through them at their leisure. All told, there are 438 separate pieces, including six sets of alphabet cards (complete with vowel sounds), two booklets, three sets of lesson cards in verse and anecdotal form, and several card sets of moral instruction. The cards are quite visually appealing, and they contain references to such contemporaries as George Berkeley, and George Wright, a noted Member of Parliament. For those with a penchant for taking a stroll down the memory lane of pedagogy and instruction, this collection is worth several visits.

The Impeachment of Andrew Johnson  

NSDL National Science Digital Library

At the end of the US Civil War, Vice President Andrew Johnson took office as the seventeenth President of the US after Abraham Lincoln's assassination. During Johnson's four-year term as a Democratic President (1865-69), his lenient Reconstruction policies toward the former Confederacy upset the Radical Republicans who controlled Congress. In response to Johnson's highhandedness, the House of Representatives voted articles of impeachment against the President, and he was tried, and subsequently exonerated, before the Senate in 1868. This site explains the key political issues behind Johnson's impeachment, details the legal and political arguments for impeachment, provides biographies and portraits for 28 key figures related to the trial, and chronicles Johnson's term as President. An instructional game that simulates the impeachment process is also included. The majority of content at this site is provided by over 200 excerpts -- including images -- from Harper's Weekly, the most prominent publication of the era.

'Tennessee' Clues  

NASA Technical Reports Server (NTRS)

This false-color image shows the area within 'Endurance Crater,' currently being investigated by the Mars Exploration Rover Opportunity. The rover is inspecting a hole it drilled into a flat rock (center) dubbed 'Tennessee,' which scientists believe may be made up of the same evaporite-rich materials as those found in 'Eagle Crater.'

The overall geography inside Endurance is more complex than scientists anticipated, with at least three distinct bands of rock visible in front of the rover. Scientists hope to investigate the second and third layers of rock for more clues to Mars' history. This image was taken on sol 133 (June 8, 2004) with the rover's panoramic camera, using the 750-, 530- and 430-nanometer filters.

NASA Astrophysics Data System (ADS)

Abstract: Researchers, policymakers, business, and industry have indicated that the United States will experience a future shortage of professionals in the Science, Technology, Engineering, and Mathematics (STEM) fields. Several strategies have been suggested to address this impending shortage, one of which includes increasing the representation of females and minorities in the STEM fields. In order to increase the representation of underrepresented students in the STEM fields, it is important to understand the motivational factors that impact underrepresented students' interest in STEM academics and extracurricular programs. Research indicates that greater confidence leads to greater interest and vice versa (Denissen et al., 2007). In this paper, the mathematics research team examined the role of practical research experience during the summer for talented minority secondary students studying in STEM fields. An undergraduate research mathematics team focused on the link between summer research and the choice of an undergraduate discipline. A Chi Square Statistical Test was used to examine Likert Scale results on the attitude of students participating in the 2006-2012 Center for Remote Sensing of Ice Sheets (CReSIS) Summer Research Programs for secondary students. This research was performed at Elizabeth City State University located in northeastern North Carolina about the factors that impact underrepresented students' choices of STEM related majors in college. Results can be used to inform and guide educators, administrators, and policy makers in developing programs and policy that support and encourage the STEM development of underrepresented students.

Evaluation of the Tennessee Child Restraint Law.  

PubMed Central

In Tennessee a law came into force January 1, 1978 requiring parents to use child restraints properly when transporting their children who are less than four years old. Alternatively, the law permits children to be held in arms, a practice known to be hazardous rather than protective. Before and after the law went into force, observations were made of children in cars exiting from shopping centers in Knoxville and Nashville, Tennessee, and in Lexington and Louisville, Kentucky, an adjacent state not having a child restraint law. More than 80 per cent of Tennessee children observed in the fourth month the law was in force were not using child restraints anchored by seat belts, although use rates increased in Tennessee (8 to 16 per cent) to a greater extent than in Kentucky (11 to 15 per cent). Moreover, due to a large increase in children traveling in arms in Nashville, there was an increase in such travel in the two Tennessee cities studied (23 to 28 per cent) relative to a decrease in those studied in Kentucky (19 to 14 per cent).

Magic Johnson and children's conceptions of AIDS.  

PubMed

Longitudinal data for a heterogeneous sample of 609 elementary school children are used to assess the long-term effects of Magic Johnson's announcement on children's HIV and AIDS conceptions. Four hypotheses are tested concerning these relationships, and background variables measured prior to Johnson's announcement are controlled. Findings suggest that Johnson's announcement increased children's HIV and AIDS knowledge and reduced their prejudice toward a hypothetical child with AIDS. No relationship is evident between the announcement and perceived vulnerability to HIV and AIDS. Males are more likely to be aware of Johnson's announcement, but its effects are more pronounced among blacks. Findings from the present research affirm the potential for celebrities like Johnson in HIV and AIDS education campaigns directed toward children. PMID:9376209

Stevens-Johnson syndrome: a case report.  

PubMed

Non-steroidal anti-inflammatory drugs are commonly prescribed in dental practice after minor oral surgical procedures such as tooth extraction. Diclofenac sodium is one of the non-steroidal anti-inflammatory drugs widely used for pain relief in dentistry. Although adverse reactions to these drugs are rare, at times they can cause a life-threatening phenomenon. Stevens-Johnson syndrome is one such potentially lethal adverse drug reaction. Most reported cases of analgesic-induced Stevens-Johnson syndrome were due to oxicams or propionic acid derivatives. There are very few detailed reports of Stevens-Johnson syndrome due to use of diclofenac. We report here a case of Stevens-Johnson syndrome which occurred due to use of diclofenac sodium. The clinical features of this condition and multidisciplinary management of the patient are described in brief. PMID:20587964

Large springs of east Tennessee  

USGS Publications Warehouse

Springs constitute an important source of water in east Tennessee, and many individual springs are capable of supplying the large quantities needed for municipal and industrial supplies. Most of the springs in east Tennessee issue from solution openings and fractured and faulted zones in limestone and dolomite of the Knox Group, Chickamauga Limestone, and Conasauga Group. The ability of these rocks to yield a sustained flow of water to springs is dependent on a system of interconnected openings through which water can infiltrate from the land surface and move to points of natural discharge. Ninety springs were selected for detailed study, and 84 of these are analyzed in terms of magnitude and variability of discharge. Of the 84 springs analyzed, 4 flow at an average rate of 10 to 100 cfs (cubic feet per second), 62 at an average rate of 1 to 10 cfs, and 18 at an average rate of 1 cfs or less. Of the 90 springs, 75 are variable in their discharge; that is, the ratio of their fluctuations to their average discharges exceeds 100 percent. Mathematical analysis of the flow recession curve of Mill Spring near Jefferson City shows that the hydrologic system contributing to the flow of the spring has an effective capacity of about 70 million cubic feet of water. The rate of depletion of this volume of water, in the absence of significant precipitation, averages 0.0056 cfs per day between the time when the hydrologic system is full and the time when the spring ceases to flow. From such a curve it is possible to determine at any time the residual volume of water remaining in the system and the expected rate of decrease in discharge from that time to cessation of flow. Correlation of discharge measurements of 22 springs with those of Mill Spring shows that rough approximations of discharge can be projected for springs for which few measurements are available. Seventeen of the springs analyzed in this manner show good correlation with Mill Spring: that is, their coefficients of correlation were 0.70 or better as compared with a perfect correlation factor of 1.00.

John Johnson Collection: Trades and Professions  

NSDL National Science Digital Library

John de Monins Johnson was a tremendous collector of printed ephemera during his life, and he was particularly keen on items which depicted people at work in various vocations. He was inspired by his work in Egypt as a papyrologist during the early 20th century, and he went on to return to Britain to help save the country's paper heritage. Johnson's collection ended up at the Bodleian Library at the University of Oxford, and this digital offering contains over 900 examples of this type of work. Visitors can look through the images by title or artist, and each item has a bibliographic record. While there are many gems here, visitors shouldn't miss the image of a brewhouse from 1747 or the trade card which has the telling heading "To All Lovers of Angling".

GEE CREEK WILDERNESS, TENNESSEE.  

USGS Publications Warehouse

On the basis of geologic, geochemical, and mine and prospect surveys, it was determined that the Gee Creek Wilderness, Tennessee has little promise for the occurrence of mineral resources. Iron ore was formerly mined, but the deposits are small, have a high phosphorous content, and are inaccessible. Shale, suitable for brick or lightweight aggregate, and sandstone, which could be utilized for crushed stone or sand, are found in the area, but are also found in areas closer to potential markets. The geologic setting precludes the presence of oil and gas resources in the surface rocks, but the possibility of finding natural gas at depth below the rocks exposed in the area cannot be discounted. Geophysical exploration would be necessary to define the local structure in rocks at depth to properly evaluate the potential of the area for gas.

Resolution requirements and the Johnson criteria revisited  

NASA Astrophysics Data System (ADS)

Since the 1950s, numerous studies have been performed within the surveillance and reconnaissance (S&R) and target acquisition (TA) communities in an attempt to predict information extraction performance as a function of image collection and quality parameters. In general, the work followed two separate paths. The TA community developed models to predict probabilities of detection, recognition, and identification as a function of target size, range, and collection system design/performance parameters (e.g., MRT, FLIR92,NVTHERM,MRC). The S&R community developed models to predict National Imagery Interpretability Ratings (NIIRS) as a function of system design and collection parameters (e.g. IR GIQE). More recently, efforts have linked the two approaches such that NIIRS can be predicted from TA models and probabilities of identification can be predicted from NIIRS. With both approaches, resolution is a dominant term. A considerable amount of variability and uncertainty results from target differences. The criteria used to define the NIIRS generalize target type, size, and level of identification specificity. The TA predictions use the Johnson recognition criteria to relate lines on the target to recognition performance. A recent paper found that TA predictions differed substantially between the visible and IR. Further, the paper reported substantial differences among vehicles in terms of a confusion matrix. This finding was not surprising in light of other research, but suggested the need for a more detailed examination and explanation of results. Accordingly, the current effort was undertaken. Data from a variety of past studies dealing with target recognition were examined relative to the Johnson criteria, along with a more detailed analysis of data from two recent TA studies. A hypothesis of target recognition performance was generated and partially validated using available data.

Biological Conditions in Streams of Johnson County, Kansas, and Nearby Missouri, 2003 and 2004  

USGS Publications Warehouse

Johnson County is one of the fastest growing and most populated counties in Kansas. Urban development affects streams by altering stream hydrology, geomorphology, water chemistry, and habitat, which then can lead to adverse effects on fish and macroinvertebrate communities. In addition, increasing sources of contaminants in urbanizing streams results in public-health concerns associated with exposure to and consumption of contaminated water. Biological assessments, or surveys of organisms living in aquatic environments, are crucial components of water-quality programs because they provide an indication of how well water bodies support aquatic life. This fact sheet describes current biological conditions of Johnson County streams and characterizes stream biology relative to urban development. Biological conditions were evaluated by collecting macroinvertebrate samples from 15 stream sites in Johnson County, Kansas, in 2003 and 2004 (fig. 1). Data from seven additional sites, collected as part of a separate study with similar objectives in Kansas and Missouri (Wilkison and others, 2005), were evaluated to provide a more comprehensive assessment of watersheds that cross State boundaries. Land-use and water- and streambed-sediment-quality data also were used to evaluate factors that may affect macroinvertebrate communities. Metrics are indices used to measure, or evaluate, macroinvertebrate response to various factors such as human disturbance. Multimetric scores, which integrated 10 different metrics that measure various aspects of macroinvertebrate communities, including organism diversity, composition, tolerance, and feeding characteristics, were used to evaluate and compare biological health of Johnson County streams. This information is useful to city and county officials for defining current biological conditions, evaluating conditions relative to State biological criteria, evaluating effects of urbanization, developing effective water-quality management plans, and documenting changes in biological conditions and water quality.

John H. Johnson, Publisher of Jet and Ebony, Passes Away  

NSDL National Science Digital Library

Once upon a time, the noted curmudgeon and celebrated journalist A.J. Liebling remarked that âÂÂFreedom of the press is limited to those who own one." John H. Johnson, was one such person who had such âÂÂfreedom," and he used his business acumen and savvy to develop a number of publications that portrayed African-Americans in a positive light to an outside world that at times seemed to ignore their presence, or merely relied on popular stereotypes when writing about their experiences in the United States. Johnson died this past Monday at age 87, and he left behind a legacy that included two immensely popular magazines aimed at African-Americans, _Ebony_ and _Jet_. In many ways, Johnson was the very real personification of that Horatio Alger âÂÂrags to richesâ archetype, as he grew up in rural poverty in Arkansas, and later went on to become the first African-American on the Forbesâ list of the wealthiest Americans. Along with offering images and articles about middle-class black America, JohnsonâÂÂs publications also confronted important social issues of the day, such as the civil rights movement, and most notably, the murder of Emmett Till. In a press release, US Representative Jesse Jackson Jr. noted that Johnson âÂÂdealt fully with all the news in the African-American community-the good, the bad, the beautiful and the ugly."The first link will lead visitors to an obituary for Johnson which appeared in TuesdayâÂÂs _New York Times_. The second link will take visitors to the official press release announcing JohnsonâÂÂs passing from the Johnson Publishing Company website. The third link leads to a piece by Corey Hall of the _Chicago Defender_ newspaper about the impact of JohnsonâÂÂs career and personal character. The fourth link will take visitors to an editorial by the _Chicago Sun-Times_â own Mary Mitchell who notes that Johnson âÂÂshowed us the power wrapped up in small dreams." The fifth link leads to a selection of quotations by Johnson, including the observation that âÂÂEvery day I run scared. ThatâÂÂs the only way I can stay ahead.â The sixth and final link leads to a nice biographical sketch (complete with helpful hypertext links) of Johnson from The HistoryMakers Project, an oral history archive based in Chicago.

Radiometric ages of Tennessee rocks  

SciTech Connect

This report compiles and summarizes all known radiometric age determinations based on bedrock samples from Tennessee. Data are available for 89 sites. Specimens record both igneous and metamorphic events ranging in age from 1.3 billion to 220 million years before present. Tennessee rocks have been dated by techniques that measure the results of four different kinds of radioactive decay: thorium-lead, uranium-lead, potassium-argon, and rubidium-strontium. Most determinations meet normal scientific standards for reliability. This study focuses on clarifying published data by bringing together geochemical, geological, and geographical information for each site. In addition to data on the age of bedrock samples, this study presents basic information on the ages of meteorites from Tennessee and on the ages of sediments and organic remains from Ice Age fossil sites and more recent archeological sites. While bedrock ages are the thrust of the report, other kinds of absolute age determinations are briefly discussed. 98 references, 11 figures, 3 tables.

Renewable Energy at NASA's Johnson Space Center  

NASA Technical Reports Server (NTRS)

NASA's Johnson Space Center has implemented a great number of renewable energy systems. Renewable energy systems are necessary to research and implement if we humans are expected to continue to grow and thrive on this planet. These systems generate energy using renewable sources - water, wind, sun - things that we will not run out of. Johnson Space Center is helping to pave the way by installing and studying various renewable energy systems. The objective of this report will be to examine the completed renewable energy projects at NASA's Johnson Space Center for a time span of ten years, beginning in 2003 and ending in early 2014. This report will analyze the success of each project based on actual vs. projected savings and actual vs. projected efficiency. Additionally, both positive and negative experiences are documented so that lessons may be learned from past experiences. NASA is incorporating renewable energy wherever it can, including into buildings. According to the 2012 JSC Annual Sustainability Report, there are 321,660 square feet of green building space on JSC's campus. The two projects discussed here are major contributors to that statistic. These buildings were designed to meet various Leadership in Energy and Environmental Design (LEED) Certification criteria. LEED Certified buildings use 30 to 50 percent less energy and water compared to non-LEED buildings. The objectives of this project were to examine data from the renewable energy systems in two of the green buildings onsite - Building 12 and Building 20. In Building 12, data was examined from the solar photovoltaic arrays. In Building 20, data was examined from the solar water heater system. By examining the data from the two buildings, it could be determined if the renewable energy systems are operating efficiently. Objectives In Building 12, the data from the solar photovoltaic arrays shows that the system is continuously collecting energy from the sun, as shown by the graph below. Building 12 has two solar inverters, located on the second floor, that collected the data from the solar photovoltaic arrays. The data displayed here is the total energy produced by the system. These are cumulative amounts, so the last point on the graph shows all of the energy collected from the system since the start of its operation. The data shown here was manually collected from the solar inverters. However, the data is also automatically recorded through EBI. Through analysis of both sets of data it was determined that the EBI data was faulty. For example, from the manually collected data it can be determined that a total of 73 kWh of energy was collected between the dates of 1/16/2014 – 1/22/2014. The EBI data reports that approximately 17800 kWh of energy was collected during the same time frame. Not only does this exceed the time frame examined, but it also exceeds the total energy collected from the start of collection as recorded from the inverters. This leads to the belief that there is a malfunction with the automatic recording of the energy. In Building 20, data was examined from the solar water heater dating back many months and found that the pump for the solar water heater system was not operating properly, as exhibited in the graph shown below. The pump operates on a solar energy system, meaning that it collects energy throughout the day from the sun. Because of this, the system would stop operating shortly after the sun set because of a lack of sunlight. At that point, the graph should show a zero flow rate, but as exhibited in the graph below, that is not the case. It is clearly shown that the pump is continuously operating, even during the night. It was also observed that the majority of the time the pump would not turn on at all, despite good weather conditions. This led to the conclusion that the pump is malfunctioning, and needs to be examined and fixed.

Application of the Johnson criteria to graphene transistors  

NASA Astrophysics Data System (ADS)

For 60 years, the Johnson criteria have guided the development of materials and the materials choices for field-effect and bipolar transistor technology. Intrinsic graphene is a semi-metal, precluding transistor applications, but only under lateral bias is a gap opened and transistor action possible. This first application of the Johnson criteria to biased graphene suggests that this material will struggle to ever achieve competitive commercial applications.

Investigation of Integrated Subsurface Processing of Landfill Gas and Carbon Sequestration, Johnson County, Kansas  

SciTech Connect

The Johnson County Landfill in Shawnee, KS is operated by Deffenbaugh Industries and serves much of metropolitan Kansas City. Refuse, which is dumped in large plastic-underlined trash cells covering several acres, is covered over with shale shortly after burial. The landfill waste, once it fills the cell, is then drilled by Kansas City LFG, so that the gas generated by anaerobic decomposition of the refuse can be harvested. Production of raw landfill gas from the Johnson County landfill comes from 150 wells. Daily production is approximately 2.2 to 2.5 mmcf, of which approximately 50% is methane and 50% is carbon dioxide and NMVOCs (non-methane volatile organic compounds). Heating value is approximately 550 BTU/scf. A upgrading plant, utilizing an amine process, rejects the carbon dioxide and NMVOCs, and upgrades the gas to pipeline quality (i.e., nominally a heating value >950 BTU/scf). The gas is sold to a pipeline adjacent to the landfill. With coal-bearing strata underlying the landfill, and carbon dioxide a major effluent gas derived from the upgrading process, the Johnson County Landfill is potentially an ideal setting to study the feasibility of injecting the effluent gas in the coals for both enhanced coalbed methane recovery and carbon sequestration. To these ends, coals below the landfill were cored and then were analyzed for their thickness and sorbed gas content, which ranged up to 79 scf/ton. Assuming 1 1/2 square miles of land (960 acres) at the Johnson County Landfill can be utilized for coalbed and shale gas recovery, the total amount of in-place gas calculates to 946,200 mcf, or 946.2 mmcf, or 0.95 bcf (i.e., 985.6 mcf/acre X 960 acres). Assuming that carbon dioxide can be imbibed by the coals and shales on a 2:1 ratio compared to the gas that was originally present, then 1682 to 1720 days (4.6 to 4.7 years) of landfill carbon dioxide production can be sequestered by the coals and shales immediately under the landfill. Three coal--the Bevier, Fleming, and Mulberry coals--are the major coals of sufficient thickness (nominally >1-foot) that can imbibe carbon dioxide gas with an enhanced coalbed injection. Comparison of the adsorption gas content of coals to the gas desorbed from the coals shows that the degree of saturation decreases with depth for the coals.

Evaluating corporate wellness and promotion programs: the cases of Johnson & Johnson Corporation and Metropolitan Life Insurance Company.  

PubMed

In 1983 the Health Systems Management Center of Case Western Reserve University (CWRU) contracted with the Business Roundtable Health Initiatives Task Force to use their survey of members as a guide to the top firms who had taken action regarding health care costs but, more importantly, who had also evaluated that action in terms of its cost implications. The mandate was to draw together representative case studies on seven firms who met those criteria for use in Business Roundtable (BRT) educational seminars and elsewhere. These cases may provide important insight for other companies who are contemplating action regarding their health care costs. They should also lead to further research on alternative actions available and the means of evaluation that should be considered. Most importantly they may provide some methodologies for top management to choose among proposals for attacking this burgeoning corporate cost. Two of the case studies presented here, Johnson & Johnson and Metropolitan Life, examine the area of wellness promotion and sickness prevention. Both of these companies believe that the employer can have a positive impact on employee health and thus corporate costs and productivity. Both also attempted to measure the benefit although Johnson & Johnson has made a significantly larger investment in this effort. The ongoing Johnson & Johnson evaluation does hold the greatest promise for measuring economic benefits. The limited results available are positive. Although financial ramifications are difficult to demonstrate, gains in employee morale are significant. PMID:10311247

How To Identify Johnson-Cook Parameters From Machining Simulations  

NASA Astrophysics Data System (ADS)

The Johnson-Cook material model is a robust material model which has demonstrated its usefulness in describing material behaviour over large ranges of strains, strain rates and temperatures. During machining the material in the shear zone undergoes strains of more than 200%, strain-rates of the order of 106 per second or more and a temperature rise of several hundreds of degrees Celsius. The determination of the Johnson-Cook parameters, which are needed to describe the material behaviour in the severe conditions found during machining, has proved to be challenging, even using the state-of-the-art experimental methods. Recent experimental methods rely on data obtained from strains of around 50% and strain rates of the order of 103 per second. In this paper, an inverse method for determining the Johnson-Cook parameters from machining simulations is described. To demonstrate the concept, a finite element model of orthogonal cutting is created and a particular Johnson-Cook parameter set is used for the simulation. It has been shown earlier that multiple Johnson-Cook parameter sets exist which give rise to almost indistinguishable chips and cutting forces for a single set of cutting parameters. In order to eliminate some of these different sets, machining simulations are carried out for two different rake angles. Using the Levenberg-Marquardt optimisation algorithm, the original Johnson-Cook parameter set is re-identified. In order to achieve this, the chip morphology and the cutting force are used to construct the objective function for minimisation. To determine the direction of the steepest descent, the Jacobian matrix is determined numerically with respect to the Johnson-Cook parameters.

Feasibility Study of Economics and Performance of Solar Photovoltaics at Johnson County Landfill  

SciTech Connect

The U.S. Environmental Protection Agency (EPA), in accordance with the RE-Powering America's Land initiative, selected the Johnson County Landfill in Shawnee, Kansas, for a feasibility study of renewable energy production. Citizens of Shawnee, city planners, and site managers are interested in redevelopment uses for landfills in Kansas that are particularly well suited for grid-tied solar photovoltaic (PV) installation. This report assesses the Johnson County Landfill for possible grid-tied PV installations and estimates the cost, performance, and site impacts of three different PV options: crystalline silicon (fixed tilt), crystalline silicon (single-axis tracking), and thin film (fixed tilt). Each option represents a standalone system that can be sized to use an entire available site area. In addition, the report outlines financing options that could assist in the implementation of a system. The feasibility of PV systems installed on landfills is highly impacted by the available area for an array, solar resource, operating status, landfill cap status, distance to transmission lines, and distance to major roads. The report findings are applicable to other landfills in the surrounding area.

Photovoltaic indium antimonide detectors have been operated at temperatures Johnson noise limited performance is realized. Under such conditions the noise equivalent power (NEP) is completely determined by the detector operating temperature, resistance, and quantum efficiency. Optimization of these parameters in the manufacture of commercially available detectors has led to 5-mum NEP's as low as 10(-15) W. The particular preamplifier is critical to the achievement of Johnson noise limited operation and is described in detail. PMID:20134905

LITTLE FROG ROADLESS AREA, TENNESSEE.  

USGS Publications Warehouse

No mineral-resource potential was identified during studies of the Little Frog Roadless Area, Tennessee. Possibilities exist, however, for the occurrence of massive sulfide-bearing rocks of the type mined in the adjacent Ducktown Basin at depth beneath the roadless area. A possibility also exists for the presence of natural gas in sedimentary rocks at great depth. Insufficient data to support these concepts precludes assessing any of the roadless area as having resource potential. A limited amount of geologic mapping coupled with seismic work would be useful to test whether rocks of the Ducktown Basin are present at depth under the roadless areas. Seismic work and drilling would be necessary also to test for the presence of gas at great depths.

The February 21, 1993 tornadoes of East Tennessee  

SciTech Connect

A series of tornadoes struck the east Tennessee area on Sunday afternoon, February 21, 1993 around Knoxville, Lenoir City, and Oak Ridge causing millions of dollars worth of damage to both homes and businesses in the area, killing one, injuring a number of persons, and leaving a large area without power for many hours or even days due to damage to the local TVA transmission line network. One tornado touched down in the Department of Energy Oak Ridge Reservation near the Oak Ridge Y-12 Plant, continued through the Union Valley business district located just east of the plant, through the adjacent University of Tennessee Arboretum and then continued into the communities of Claxton and Powell. The path length of the tornado was approximately 13 miles. Damage to the Y-12 Plant was minimal, but the Union Valley business district was seriously damaged, including the Fusion Energy Design Center (FEDC) which houses a number of DOE related projects. The preliminary cost estimate of the damage to DOE facilities (both at Y-12 and at the FEDC) was around $520,000. This paper describes the local meteorological data, the tornado that struck near the Y-12 plant, the resulting damage both to the DOE facilities and to the surrounding communities, the plant emergency response and recovery activities, and the current hazard analyses being undertaken at the plant.

How To Identify Johnson-Cook Parameters From Machining Simulations  

Microsoft Academic Search

The Johnson-Cook material model is a robust material model which has demonstrated its usefulness in describing material behaviour over large ranges of strains, strain rates and temperatures. During machining the material in the shear zone undergoes strains of more than 200%, strain-rates of the order of 106 per second or more and a temperature rise of several hundreds of degrees

Numerical solution of shear localization in Johnson–Cook materials  

Microsoft Academic Search

To compute shear localization, a recently developed numerical scheme is adapted for application to certain types of materials described by a Johnson–Cook model. In the context of a slab geometry, the numerical scheme requires discretization only in the time variable to yield the stress and temperature in a shear band. Numerical results for several materials are presented.

Hydrologic data for the Obed River watershed, Tennessee  

USGS Publications Warehouse

The Obed River watershed drains a 520-square-mile area of the Cumberland Plateau physiographic region in the Tennessee River basin. The watershed is underlain by conglomerate, sandstone, and shale of Pennsylvanian age, which overlie Mississippian-age limestone. The larger creeks and rivers of the Obed River system have eroded gorges through the conglomerate and sandstone into the deeper shale. The largest gorges are up to 400 feet deep and are protected by the Wild and Scenic Rivers Act as part of the Obed Wild and Scenic River, which is managed by the National Park Service. The growing communities of Crossville and Crab Orchard, Tennessee, are located upstream of the gorge areas of the Obed River watershed. The cities used about 5.8 million gallons of water per day for drinking water in 2010 from Lake Holiday and Stone Lake in the Obed River watershed and Meadow Park Lake in the Caney Fork River watershed. The city of Crossville operates a wastewater treatment plant that releases an annual average of about 2.2 million gallons per day of treated effluent to the Obed River, representing as much as 10 to 40 percent of the monthly average streamflow of the Obed River near Lancing about 35 miles downstream, during summer and fall. During the past 50 years (1960–2010), several dozen tributary impoundments and more than 2,000 small farm ponds have been constructed in the Obed River watershed. Synoptic streamflow measurements indicate a tendency towards dampened high flows and slightly increased low flows as the percentage of basin area controlled by impoundments increases.

Karst subsidence in East Tennessee  

SciTech Connect

Waste disposal site selection and facility design in regions dominated by carbonate bedrock must carefully consider karst development and the factors which contribute to subsidence activity. The Department of Energy's (DOE) Oak Ridge National Laboratory has completed a three phase study of karst subsidence in East Tennessee to quantify historical subsidence activity. The purpose of the study was to determine the principal factors which cause karst subsidence in the region. Techniques used and results obtained in this study form a basis for more detailed risk assessment at the local scale within the region. As development pressures diminish available land for various uses, risk-based land use decisions must be made to site critical facilities. To fulfill the study objectives a three phase study was designed including, (1) collection of subsidence data and compilation of a database, (2) performance of detailed studies of subsidence in three, two-to-five square-mile areas, and (3) synthesis of data obtained to; quantify the predominant sinkhole collapse dimensions, and identify events prior to subsidence or collapse events which may have caused the event, and estimate the intensity of subsidence as a function of geologic unit within subregional areas of higher and lower subsidence risk. 4 refs., 7 figs., 2 tabs.

Stemming the tide - arms control in the Johnson years  

SciTech Connect

Nobel laureate Seaborg has long combined eminent research in science with distinguished service to his country. From 1961 to 1971 he was chairman of the Atomic Energy Commission, and Stemming the Tide deals with events during the Lyndon Johnson presidency, in many of which Seaborg was a participant. The book, rich in detail and including some material not previously made public, is based on Seaborg's daily diary, on official letters and papers during his AEC tenure, on archival materials in the Johnson Library, and on appropriate secondary sources. Benjamin Loeb, his former assistant, again joins him in authorship; earlier the two wrote, on a related topic, Kennedy, Khruschev and the Test Ban (Univ. of California Press, 1981). Both volumes give first-hand accounts of important aspects of post WW-II arms developments.

The mathematics of Brownian motion and Johnson noise  

NASA Astrophysics Data System (ADS)

One reason why Brownian motion and Johnson noise are difficult subjects to teach is that their mathematical requirements transcend the capabilities of ordinary differential calculus. Presented here is an exposition of the needed generalization of calculus, namely continuous Markov process theory, in a form that should be accessible to advanced physics undergraduates. It is shown how this mathematical framework enables one to give clear, concise derivations of all the principal results of Brownian motion and Johnson noise, including fluctuation-dissipation formulas, auto-covariance transport formulas, spectral density formulas, Nyquist's formula, the notions of white and 1/f2 noise, and an accurate numerical simulation algorithm. An added benefit of this exposition is a clearer view of the mathematical connection between the two very different approaches to Brownian motion taken by Einstein and Langevin in their pioneering papers of 1905 and 1908.

The memorable life of Hosmer A. Johnson, early midwestern laryngologist.  

PubMed

Hosmer A. Johnson, one of the early laryngologists in the Midwest, graduated in 1852 from Rush Medical College, and was the first intern in Chicago. With four other faculty members he left Rush in 1859 to establish what subsequently became the Northwestern University Medical School. He taught many subjects and was extremely active in local and national societies. An interest in diseases of the chest led him into laryngology and he became a charter member of the American Laryngological Association, where he reported on congenital tumors of the larynx, laryngeal paralysis, and cancer of the larynx. Dr. Johnson was a master of six or seven foreign languages, a versatile civic leader, a talented orator, and was greatly admired for his medical skills. The breadth of his accomplishments and character made for a truly memorable life. PMID:6354036

Johnson Noise Thermometry for Advanced Small Modular Reactors  

SciTech Connect

Temperature is a key process variable at any nuclear power plant (NPP). The harsh reactor environment causes all sensor properties to drift over time. At the higher temperatures of advanced NPPs the drift occurs more rapidly. The allowable reactor operating temperature must be reduced by the amount of the potential measurement error to assure adequate margin to material damage. Johnson noise is a fundamental expression of temperature and as such is immune to drift in a sensor’s physical condition. In and near the core, only Johnson noise thermometry (JNT) and radiation pyrometry offer the possibility for long-term, high-accuracy temperature measurement due to their fundamental natures. Small Modular Reactors (SMRs) place a higher value on long-term stability in their temperature measurements in that they produce less power per reactor core and thus cannot afford as much instrument recalibration labor as their larger brethren. The purpose of the current ORNL-led project, conducted under the Instrumentation, Controls, and Human-Machine Interface (ICHMI) research pathway of the U.S. Department of Energy (DOE) Advanced SMR Research and Development (R&D) program, is to develop and demonstrate a drift free Johnson noise-based thermometer suitable for deployment near core in advanced SMR plants.

Food habits of bobcats (Lynx rufus) in eastern Tennessee were determined from analyzing 176 cat samples collected on the Oak Ridge National Environmental Research Park. Remains of cottontail rabbits (Sylvilagus floridanus) were the most frequently occurring food item. White-tail deer (Odocoileus virginianus) and pine vole (Microtus pinetorum) remains also were found frequently in samples. Data obtained from this study indicated that food preferences for bobcats in eastern Tennessee are similar to those in other southeastern states where the habitat is similar to the Oak Ridge area and somewhat different from those with significantly different habitat.

Dubin-Johnson-like black liver with normal bilirubin level.  

PubMed

Black liver is a common finding in Dubin-Johnson syndrome (DJS), which is caused by the lack of multidrug resistance-associated protein 2 (MRP2). Impaired excretion of epinephrine metabolites is believed to be a cause of black liver in DJS. Recently, we experienced a patient with black liver whose serum bilirubin level was normal. Coarse brown granules were observed in the hepatocytes, and this finding closely resembled that observed in DJS. However, the granules were negative for Schmorl staining. The MRP2 gene did not show any mutation. Immunostaining study demonstrated MRP2 protein expression in the liver, and it was localized in the canalicular membranes of hepatocytes. This case illustrates for the first time that DJS is not the only cause of black liver. PMID:15565410

Johnson watch the Saturn V vehicle roar skyward carrying the Apollo 11 manned spacecraft into the vast regions of space. On a trajectory to the Moon, the craft lifted off from launch pad 39 at Kennedy Space Flight Center (KSC) on July 16, 1969. The moon bound crew included astronauts Neil A. Armstrong, commander; Michael Collins, Command Module (CM) pilot; and Edwin E. Aldrin Jr., Lunar Module (LM) pilot. The mission finalized with splashdown on July 24, 1969. With the success of Apollo 11, the national objective to land men on the Moon and return them safely to Earth had been accomplished. The Saturn V was developed by the Marshall Space Flight Center (MSFC) under the direction of Werher von Braun.

Study of Lyndon B. Johnson Space Center utility systems  

NASA Technical Reports Server (NTRS)

The results of an engineering study of potential energy saving utility system modifications for the NASA Lyndon B. Johnson Space Center are presented. The objective of the study was to define and analyze utility options that would provide facility energy savings in addition to the approximately 25 percent already achieved through an energy loads reduction program. A systems engineering approach was used to determine total system energy and cost savings resulting from each of the ten major options investigated. The results reported include detailed cost analyses and cost comparisons of various options. Cost are projected to the year 2000. Also included are a brief description of a mathematical model used for the analysis and the rationale used for a site survey to select buildings suitable for analysis.

Johnson's Island, Unlocking a Civil War Prison: Interactive Dig  

NSDL National Science Digital Library

Johnson's Island in Ohio is arguably the state's best known Civil War landmark. In 1861, the U.S. Army leased 40 cleared acres of the island in order to create a prisoner of war depot. The depot was in operation from 1862 to 1865, when the site began new life as an agricultural station. Recently, David Bush and some of his archaeology colleagues began an excavation on the site in order to locate the barracks that once housed Confederate POWs. This site, offered by Archaeology Magazine, allows users to journey along as the team performs their work. Visitors can look over the field reports filed by the team, read an interview with David Bush, and also read letters and diary notes from the original prisoners and their guards.

Johnson - Cook Strength Models for Mild and DP 590 Steels  

SciTech Connect

Automotive steels, Mild and Dual Phase590 (DP590) are characterized in tension at room temperature, using the quasi-static and split Hopkinson bar techniques at various strain rates ranging from {approx}10-3/s to {approx}1800/s. Tension stress-strain data for both the steels are analyzed to determine the Johnson-Cook Strength model constants, J-C strength model constants for mild steel are A=217 MPa, B = 234 MPa, n = 0.643 and C = 0.076 and for DP590 steel are A = 430 MPa, B = 824 MPa, n = 0.510 and C = 0.017. Higher value of strain rate sensitivity constant C for mild steel (0.076) compared to DP 590 (0.017) is also reflected in the stress- strain data at various strain rates.

Tennessee meets the challenge of dyslexia.  

PubMed

In 1993, the Tennessee General Assembly voted funds to establish a model unit of integrated services and research to address the full scope of issues associated with dyslexia. Dyslexia is characterized as significant difficulty in reading and spelling individual words. In the Tennessee Center for the Study and Treatment of Dyslexia, these problems are presumed to be the consequence of a phonological core deficit. When compared to typical readers, matched for age or reading level, dyslexic readers evidence average listening comprehension, a relative strength in reading comprehension, deficits in word recognition and spelling, and severe deficits in word analysis as well as in awareness and manipulation of phonemes. Integration of this information yields a diagnostic profile that may be applied in the differential diagnosis of dyslexia both in clinical and school settings. This paper presents an overview of the Tennessee Center for Dyslexia and the services it provides as well as its guidelines for interpreting the results of norm-referenced tests and criterion-referenced measures to diagnose dyslexia and plan appropriate intervention. Frith's (1985, 1986) developmental framework for reading acquisition is integrated with the assessment data to outline an instructional plan that addresses mastery of skills within and across the hierarchical phases-logographic, alphabetic, and orthographic-of reading development.

Invincible Cities  

NSDL National Science Digital Library

Throughout history, cities have risen and fallen from prominence, and in recent times more attention has been paid to why this ebb and flow persists across the centuries. Documenting this process has increasingly been the province of historians, archaeologists, city planners, sociologists, and of course, photographers. Many photographers have been very interested in the world of post-industrial urban decay, and Camilo Jose Vergara is one of the best. With financial support from the Ford Foundation, this website brings together VergaraâÂÂs photographic record of the cities of Camden, New Jersey and Richmond, California in exquisite geographic and visual detail. First-time visitors will want to read through the introduction to the project offered by Vergara, and then perhaps click on the question mark on the homepage for a brief primer on how to use the user interface for each city. At that point, visitors shouldnâÂÂt be afraid to look over both cities, as they can zoom in and out around a number of interesting locales, including abandoned factories, old piers, and gated communities. Short of wandering through these cities in a peripatetic fashion, this website serves as an interesting introduction to some overlooked aspects of urbanity.

Using data from the National Violence Against Women Survey (NVAWS) and building on the work of Johnson and Leone (2005), this study is a comparison of the female and male victims of intimate terrorism (IT) and an examination of the effects of IT on male victims. The findings indicate that IT, as a type of violence, does not have the same characteristics when the victims are men. Men involved in a terroristic marriage are not more likely to be injured, do not miss work more frequently, and are not more likely to report symptoms of depression compared to men involved in situational couple violence (SCV). Other findings appear to point to gender symmetry between women and men regarding IT, although broad conclusions based on these findings cannot be made in the absence of a sufficient means to measure the level of coercion within the relationship. Additional research is needed with more innovative and complete measures of control, the defining characteristic of IT. PMID:24672995

Carbon Nanotube Activities at NASA-Johnson Space Center  

NASA Technical Reports Server (NTRS)

Research activities on carbon nanotubes at NASA-Johnson Space Center include production, purification, characterization and their applications for human space flight. In-situ diagnostics during nanotube production by laser oven process include collection of spatial and temporal data of passive emission and laser induced fluorescence from C2, C3 and Nickel atoms in the plume. Details of the results from the "parametric study" of the pulsed laser ablation process indicate the effect of production parameters including temperature, buffer gas, flow rate, pressure, and laser fluence. Improvement of the purity by a variety of steps in the purification process is monitored by characterization techniques including SEM, TEM, Raman, UV-VIS-NIR and TGA. A recently established NASA-JSC protocol for SWCNT characterization is undergoing revision with feedback from nanotube community. Efforts at JSC over the past five years in composites have centered on structural polymednanotube systems. Recent activities broadened this focus to multifunctional materials, supercapacitors, fuel cells, regenerable CO2 absorbers, electromagnetic shielding, radiation dosimetry and thermal management systems of interest for human space flight. Preliminary tests indicate improvement of performance in most of these applications because of the large surface area as well as high electrical and thermal conductivity exhibited by SWCNTs.

Nanomaterials Work at NASA-Johnson Space Center  

NASA Technical Reports Server (NTRS)

Nanomaterials activities at NASA-Johnson Space Center focus on single wall carbon nanotube production, characterization and their applications for aerospace. Nanotubes are produced by arc and laser methods and the growth process is monitored by in-situ diagnostics using time resolved passive emission and laser induced fluorescence of the active species. Parametric study of both these processes are conducted to monitor the effect of production parameters including temperature, buffer gas, flow rate, pressure, laser fluence and arc current. Characterization of the nanotube material is performed using the NASA-JSC protocol developed by combining analytical techniques of SEM, TEM, UV-VIS-NIR absorption, Raman, and TGA. Efforts at JSC over the past five years in composites have centered on structural polymernanotube systems.

Chandra X-Ray Observatory (CXO) at Johnson Space Center  

NASA Technical Reports Server (NTRS)

This Quick Time movie depicts the Chandra X-Ray Observatory (CXO), formerly Advanced X-Ray Astrophysics Facility (AXAF), in its entirety, at the orbital processing facility at the Johnson Space Center. In 1999, the AXAF was renamed the CXO in honor of the late Indian-American Novel Laureate Subrahmanyan Chandrasekhar. The CXO is the most sophisticated and the world's most powerful x-ray telescope ever built. It is designed to observe x-rays from high energy regions of the Universe, such as hot gas in the remnants of exploded stars. It produces picture-like images of x-ray emissions analogous to those made in visible light, as well as gathers data on the chemical composition of x-ray radiating objects. The CXO helps astronomers worldwide better understand the structure and evolution of the universe by studying powerful sources of x-rays such as exploding stars, matter falling into black holes, and other exotic celestial objects. TRW, Inc. was the prime contractor for the development of the CXO and NASA's Marshall Space Flight Center was responsible for its project management. The Smithsonian Astrophysical Observatory controls science and flight operations of the CXO for NASA from Cambridge, Massachusetts. The Observatory was launched July 22, 1999 aboard the Space Shuttle Columbia, STS-93 mission.

Johnson Space Center's regenerative life support systems test bed  

NASA Technical Reports Server (NTRS)

The Regenerative Life Support System (RLSS) Test Bed at NASA's Johnson Space Center is an atmospherically closed, controlled environment facility for the evaluation of regenerative life support systems using higher plants in conjunction with physicochemical life support systems. When completed, the facility will be comprised of two large scale plant growth chambers, each with approximately 10 m(exp 2) growing area. One of the two chambers, the Variable Pressure Growth Chamber (VPGC), will be capable of operating at lower atmospheric pressures to evaluate a range of environments that may be used in Lunar or Martian habitats; the other chamber, the Ambient Pressure Growth Chamber (APGC) will operate at ambient atmospheric pressure. The root zone in each chamber will be configurable for hydroponic or solid state media systems. Research will focus on: (1) in situ resource utilization for CELSS systems, in which simulated lunar soils will be used in selected crop growth studies; (2) integration of biological and physicochemical air and water revitalization systems; (3) effect of atmospheric pressure on system performance; and (4) monitoring and control strategies.

NASA Technical Reports Server (NTRS)

The Regenerative Life Support Systems (RLSS) Test Bed at NASA's Johnson Space Center is an atmospherically closed, controlled environment facility for human testing of regenerative life support systems using higher plants in conjunction with physicochemical life support systems. The facility supports NASA's Advanced Life Support (ALS) Program. The facility is comprised of two large scale plant growth chambers, each with approximately 11 m2 growing area. The root zone in each chamber is configurable for hydroponic or solid media plant culture systems. One of the two chambers, the Variable Pressure Growth Chamber (VPGC), is capable of operating at lower atmospheric pressures to evaluate a range of environments that may be used in a planetary surface habitat; the other chamber, the Ambient Pressure Growth Chamber (APGC) operates at ambient atmospheric pressure. The air lock of the VPGC is currently being outfitted for short duration (1 to 15 day) human habitation at ambient pressures. Testing with and without human subjects will focus on 1) integration of biological and physicochemical air and water revitalization systems; 2) effect of atmospheric pressure on system performance; 3) planetary resource utilization for ALS systems, in which solid substrates (simulated planetary soils or manufactured soils) are used in selected crop growth studies; 4) environmental microbiology and toxicology; 5) monitoring and control strategies; and 6) plant growth systems design. Included are descriptions of the overall design of the test facility, including discussions of the atmospheric conditioning, thermal control, lighting, and nutrient delivery systems.

Clinical profiles of Stevens-Johnson syndrome among Thai patients.  

PubMed

The objective of this study was to demonstrate the clinical profiles of Stevens-Johnson syndrome (SJS) in Thai patients, and to compare those clinical features between younger and older patients. Medical records of all patients with SJS who were admitted to Srinagarind Hospital Medical School, Khon Kaen, Thailand, from January 2002 to December 2014 were reviewed. Epidemiological features, etiologies, treatment and clinical outcomes were collected. There were 45 patients with SJS during the 10-year period. Females were the majority (57.8%) and the median age was 49 years. Hepatitis was the most frequent complication (67.5%). Phenytoin (15.6%), sulfonamide drugs (15.6%) and allopurinol (13.3%) were implicated as leading causes of SJS. Steroids were prescribed in 37 cases (82.2%). The mortality rate was 4.4%. Comparing older patients to younger patients, allopurinol appeared to be the main instigating drug to develop SJS with an odds ratio of 5.6 (95% confidence interval, 2.8-10.6). In conclusion, clinical features of Thai patients with SJS were similar to other reports. Allopurinol had the strongest association with SJS in older patients as compared to the younger ones.

Hybrid vision activities at NASA Johnson Space Center  

NASA Technical Reports Server (NTRS)

NASA's Johnson Space Center in Houston, Texas, is active in several aspects of hybrid image processing. (The term hybrid image processing refers to a system that combines digital and photonic processing). The major thrusts are autonomous space operations such as planetary landing, servicing, and rendezvous and docking. By processing images in non-Cartesian geometries to achieve shift invariance to canonical distortions, researchers use certain aspects of the human visual system for machine vision. That technology flow is bidirectional; researchers are investigating the possible utility of video-rate coordinate transformations for human low-vision patients. Man-in-the-loop teleoperations are also supported by the use of video-rate image-coordinate transformations, as researchers plan to use bandwidth compression tailored to the varying spatial acuity of the human operator. Technological elements being developed in the program include upgraded spatial light modulators, real-time coordinate transformations in video imagery, synthetic filters that robustly allow estimation of object pose parameters, convolutionally blurred filters that have continuously selectable invariance to such image changes as magnification and rotation, and optimization of optical correlation done with spatial light modulators that have limited range and couple both phase and amplitude in their response.

Hydrogeologic framework and ground-water resources at Seymour Johnson Air Force Base, North Carolina  

USGS Publications Warehouse

A preliminary hydrogeologic framework of the Seymour Johnson Air Force Base was constructed from published data, available well data, and reports from Air Base files, City of Goldsboro and Wayne County records, and North Carolina Geological Survey files. Borehole geophysical logs were run in selected wells; and the surficial, Black Creek, and upper Cape Fear aquifers were mapped. Results indicate that the surficial aquifer appears to have the greatest lateral variability of clay units and aquifer material of the three aquifers. A surficial aquifer water-level surface map, constructed from selected monitoring wells screened exclusively in the surficial aquifer, indicates the general direction of ground-water movement in this mostly unconfined aquifer is toward the Neuse River and Stoney Creek. However, water-level gradient data from a few sites in the surficial aquifer did not reflect this trend, and there are insufficient hydrologic and hydrogeologic data to determine the cause of these few anamalous measurements. The Black Creek aquifer underlies the surficial aquifer and is believed to underlie most of Wayne County, including the Air Base where the aquifer and overlying confining unit are estimated from well log data to be as much as 100 feet thick. The Black Creek confining unit ranges in thickness from less than 8 feet to more than 20 feet. There are currently no accessible wells screened exclusively in the Black Creek aquifer from which to measure water levels. The upper Cape Fear aquifer and confining unit are generally found at depths greater than 80 feet below land surface at the Air Base, and are estimated to be as much as 70 feet thick. Hydrologic and hydrogeologic data are insufficient to determine localized surficial aquifer hydrogeology, ground-water movement at several sites, or hydraulic head differences between the three aquifers.

Quality of streams in Johnson County, Kansas, 2002--10  

USGS Publications Warehouse

Stream quality in Johnson County, northeastern Kansas, was assessed on the basis of land use, hydrology, stream-water and streambed-sediment chemistry, riparian and in-stream habitat, and periphyton and macroinvertebrate community data collected from 22 sites during 2002 through 2010. Stream conditions at the end of the study period are evaluated and compared to previous years, stream biological communities and physical and chemical conditions are characterized, streams are described relative to Kansas Department of Health and Environment impairment categories and water-quality standards, and environmental factors that most strongly correlate with biological stream quality are evaluated. The information is useful for improving water-quality management programs, documenting changing conditions with time, and evaluating compliance with water-quality standards, total maximum daily loads (TMDLs), National Pollutant Discharge Elimination System (NPDES) permit conditions, and other established guidelines and goals. Constituent concentrations in water during base flow varied across the study area and 2010 conditions were not markedly different from those measured in 2003, 2004, and 2007. Generally the highest specific conductance and concentrations of dissolved solids and major ions in water occurred at urban sites except the upstream Cedar Creek site, which is rural and has a large area of commercial and industrial land less than 1 mile upstream on both sides of the creek. The highest base-flow nutrient concentrations in water occurred downstream from wastewater treatment facilities. Water chemistry data represent base-flow conditions only, and do not show the variability in concentrations that occurs during stormwater runoff. Constituent concentrations in streambed sediment also varied across the study area and some notable changes occurred from previously collected data. High organic carbon and nutrient concentrations at the rural Big Bull Creek site in 2003 decreased to at least one-fourth of those concentrations in 2007 and 2010 likely because of the reduction in upstream wastewater discharge contributions. The highest concentrations of trace metals in 2010 occurred at urban sites on Mill and Indian Creeks. Zinc was the only metal to exceed the probable effects concentration in 2010, which occurred at a site on Indian Creek. In 2007, chromium and nickel at the upstream urban Cedar Creek site exceeded the probable effects concentrations, and in 2003, no metals exceeded the probable effects concentrations. Of 72 organic compounds analyzed in streambed sediment, 26 were detected including pesticides, polycyclic aromatic hydrocarbons (PAHs), fuel products, fragrances, preservatives, plasticizers, manufacturing byproducts, flame retardants, and disinfectants. All 6 PAH compounds analyzed were detected, and the probable effects concentrations for 4 of the 6 PAH compounds analyzed were exceeded in 2010. Only five pesticide compounds were detected in streambed sediment, including carbazole and four pyrethroid compounds. Chronic toxicity guidelines for pyrethroid compounds were exceeded at five sites. Biological conditions reflected a gradient in urban land use, with the less disturbed streams located in rural areas of Johnson County. About 19 percent of sites in 2010 (four sites) were fully supporting of aquatic life on the basis of the four metrics used by Kansas Department of Health and Environment to categorize sites. This is a notable difference compared to previous years when no sites (in 2003 and 2004) or just one site (in 2007) was fully supporting of aquatic life. Multimetric macroinvertebrate scores improved at the Big Bull Creek site where wastewater discharges were reduced in 2007. Environmental variables that consistently were highly negatively correlated with biological conditions were percent impervious surface and percent urban land use. In addition, density of stormwater outfall points adjacent to streams was significantly negatively correlated with biological conditions. Specific conductance of water and sum of PA

Regionalization of low-flow characteristics of Tennessee streams  

USGS Publications Warehouse

Procedures for estimating 3-day 2-year, 3-day 10-year, 3-day 20-year, and 7-day 10-year low flows at ungaged stream sites in Tennessee are based on surface geology and drainage area size. One set of equations applies to west Tennessee streams, and another set applies to central and east Tennessee streams. The equations do not apply to streams where flow is significantly altered by activities of man. Standard errors of estimate of equations for west Tennessee are 24 to 32% and for central and east Tennessee 31 to 35%. Streamflow recession indexes, in days/log cycle, are used to account for effects of geology of the drainage basin on low flow of streams. The indexes in Tennessee range from 32 days/log cycle for clay and shale to 350 days/log cycle for gravel and sand, indicating different aquifer characteristics of the geologic units that sustain streamflows during periods of no surface runoff. Streamflow recession rate depends primarily on transmissivity and storage characteristics of the aquifers, and the average distance from stream channels to basin divides. Geology and drainage basin size are the most significant variables affecting low flow in Tennessee streams according to regression analyses. (Author 's abstract)

Regionalization of winter low-flow characteristics of Tennessee streams  

USGS Publications Warehouse

Procedures were developed for estimating winter (December-April) low flows at ungaged stream sites in Tennessee based on surface geology and drainage area size. One set of equations applies to West Tennessee streams, and another set applies to Middle and East Tennessee streams. The equations do not apply to streams where flow is significantly altered by the activities of man. Standard errors of estimate of equations for West Tennessee are 22% - 35% and for middle and East Tennessee 31% - 36%. Statistical analyses indicate that summer low-flow characteristics are the same as annual low-flow characteristics, and that winter low flows are larger than annual low flows. Streamflow-recession indexes, in days per log cycle of decrease in discharge, were used to account for effects of geology on low flow of streams. The indexes in Tennessee range from 32 days/log cycle for clay and shale to 350 days/log cycle for gravel and sand, indicating different aquifer characteristics of the geologic units that contribute to streamflows during periods of no surface runoff. Streamflow-recession rate depends primarily on transmissivity and storage characteristics of the aquifers, and the average distance from stream channels to basin divides. Geology and drainage basin size are the most significant variables affecting low flow in Tennessee streams according to regression analyses. (Author 's abstract)

City 2020+  

NASA Astrophysics Data System (ADS)

This research initiative CITY 2020+ assesses the risks and opportunities for residents in urban built environments under projected demographic and climate change for the year 2020 and beyond, using the City of Aachen as a case study. CITY 2020+ develops scenarios, options and tools for planning and developing sustainable future city structures. We investigate how urban environment, political structure and residential behavior can best be adapted, with attention to the interactions among structural, political, and sociological configurations and with their consequences on human health. Demographers project that in the EU-25-States by 2050, approximately 30% of the population will be over age 65. Also by 2050, average tem¬peratures are projected to rise by 1 to 2 K. Combined, Europe can expect enhanced thermal stress and higher levels of particulate matter. CITY 2020+ amongst other sub-projects includes research project dealing with (1) a micro-scale assessment of blockages to low-level cold-air drainage flow into the city centre by vegetation and building structures, (2) a detailed analysis of the change of probability density functions related to the occurrence of heat waves during summer and the spatial and temporal structure of the urban heat island (UHI) (3) a meso-scale analysis of particulate matter (PM) concentrations depending on topography, local meteorological conditions and synoptic-scale weather patterns. First results will be presented specifically from sub-projects related to vegetation barriers within cold air drainage, the assessment of the UHI and the temporal and spatial pattern of PM loadings in the city centre. The analysis of the cold air drainage flow is investigated in two consecutive years with a clearing of vegetation stands in the beginning of the second year early in 2010. The spatial pattern of the UHI and its possible enhancement by climate change is addressed employing a unique setup using GPS devices and temperature probes fixed to several public transport units running all across the city. This is accompanied by an analysis of probability density functions (PDF) for heat waves based on recent climate data and climate projections. A dense net of 40 PM measurement sites is operated in order to obtain the spatial pattern of PM concentration as depending on meteorological condition and location. It is lined out how this climate related sub-projects interact with investigations on social networks, governance issues, buildings structure development and health outcome. Related to the later the chemical composition of PM is analyzed in more detail and related to the spatial patterns of health deficiencies. At a later stage City2020+ will propose new strategies based on cooperation from the fields of medicine, geography, sociology, history, civil engineering, and architecture for adapting the city for future needs. The Project CITY 2020+ is part of the interdisciplinary Project House HumTec (Human Sciences and Technology) at RWTH Aachen University funded by the Excellence Initiative of the German federal and state governments through the Deutsche Forschungsgemeinschaft (German Research Foundation, DFG).

Probabilistic Analysis for Comparing Fatigue Data Based on Johnson-Weibull Parameters  

NASA Technical Reports Server (NTRS)

Leonard Johnson published a methodology for establishing the confidence that two populations of data are different. Johnson's methodology is dependent on limited combinations of test parameters (Weibull slope, mean life ratio, and degrees of freedom) and a set of complex mathematical equations. In this report, a simplified algebraic equation for confidence numbers is derived based on the original work of Johnson. The confidence numbers calculated with this equation are compared to those obtained graphically by Johnson. Using the ratios of mean life, the resultant values of confidence numbers at the 99 percent level deviate less than 1 percent from those of Johnson. At a 90 percent confidence level, the calculated values differ between +2 and 4 percent. The simplified equation is used to rank the experimental lives of three aluminum alloys (AL 2024, AL 6061, and AL 7075), each tested at three stress levels in rotating beam fatigue, analyzed using the Johnson- Weibull method, and compared to the ASTM Standard (E739 91) method of comparison. The ASTM Standard did not statistically distinguish between AL 6061 and AL 7075. However, it is possible to rank the fatigue lives of different materials with a reasonable degree of statistical certainty based on combined confidence numbers using the Johnson- Weibull analysis. AL 2024 was found to have the longest fatigue life, followed by AL 7075, and then AL 6061. The ASTM Standard and the Johnson-Weibull analysis result in the same stress-life exponent p for each of the three aluminum alloys at the median, or L(sub 50), lives

Assessment of surface-water quality and water-quality control alternatives, Johnson Creek Basin, Oregon  

USGS Publications Warehouse

Johnson Creek flows through a basin of approximately 51 square miles with mixed land uses over a reach of approximately 24 river miles from southeast of Gresham, Oregon, to its confluence with the Willamette River in Milwaukie, Oregon. Land uses within the basin include forested and agricultural lands, suburban residential, urban, and light industrial. Surface runoff and ground-water flow from the basin's areas of various land-use contain concentrations of some nutrients, trace elements, and organic compounds at levels exceeding U.S. Environmental Protection Agency (USEPA) criteria. Concentrations of dissolved cadmium, copper, lead, mercury, and silver, total recoverable chlordane, dieldrin, and dichlorodiphenyltrichloroethane (DDT) plus metabolites indicate that sources of at least one or more of these constituents exist in virtually every reach of Johnson Creek. Crystal Springs Creek is a major source of nutrients in lower Johnson Creek. Concentrations of dissolved nitrate and orthophosphorus in Johnson Creek are elevated at low flow, and are reduced by dilution when urban runoff flows into the creek during storms. Total-phosphorus concentrations exceed USEPA criteria at several sites in Johnson Creek during low flow, and at all sites during periods of storm runoff. The low-flow concentration of dissolved silver exceeded the USEPA Fresh Water Chronic Toxicity (FWCT) criterion only in Crystal Springs Creek. Concentrations of dissolved cadmium, copper, lead, and mercury exceeded FWCT criteria at selected sites in Johnson creek basin during storm runoff.

Activities of asumlam (methyl((4-aminophenyl)sulfonyl)carbamate), dalapon (2,2-dichloropropionic acid) and asulam/dalapon combinations on itchgrass (Rottboellia exaltata L.f.) and johnson grass (Sorghum halepense (L.) Pers.) were examined. When metabolism of /sup 14/C-asulam was monitored, seven days after application, 97-100% of recovered /sup 14/C co-chromatographed with /sup 14/C-asulam. Itchgrass exhibited rapid uptake of /sup 14/C-asulam within 8 hr after application. Asumlam concentrations remained constant in the plant between 8 and 72 hr. Johnson grass plants showed a differential response to asulam and asulam/dalapon treatments. Asulam-treated johnson grass absorbed 26-34% /sup 14/C within 2 hr with no future significant increase in absorption in absorption through 72 hr. Treatment of johnson grass with asulam/dalapon enhanced /sup 14/C absorption with time. At 24 and 72 hr /sup 14/C levels were double that absorbed from treatment of asulam alone. Movement of /sup 14/C-asulam in the apoplast and symplast of both itchgrass and johnson grass was noted. The highest radiolabel accumulated in the lower leaves of itchgrass and remained in the treated leaf of johnson grass.

Probabilistic Analysis for Comparing Fatigue Data Based on Johnson-Weibull Parameters  

NASA Technical Reports Server (NTRS)

Probabilistic failure analysis is essential when analysis of stress-life (S-N) curves is inconclusive in determining the relative ranking of two or more materials. In 1964, L. Johnson published a methodology for establishing the confidence that two populations of data are different. Simplified algebraic equations for confidence numbers were derived based on the original work of L. Johnson. Using the ratios of mean life, the resultant values of confidence numbers deviated less than one percent from those of Johnson. It is possible to rank the fatigue lives of different materials with a reasonable degree of statistical certainty based on combined confidence numbers. These equations were applied to rotating beam fatigue tests that were conducted on three aluminum alloys at three stress levels each. These alloys were AL 2024, AL 6061, and AL 7075. The results were analyzed and compared using ASTM Standard E739-91 and the Johnson-Weibull analysis. The ASTM method did not statistically distinguish between AL 6010 and AL 7075. Based on the Johnson-Weibull analysis confidence numbers greater than 99 percent, AL 2024 was found to have the longest fatigue life, followed by AL 7075, and then AL 6061. The ASTM Standard and the Johnson-Weibull analysis result in the same stress-life exponent p for each of the three aluminum alloys at the median or L(sub 50) lives.

Community reaction to aircraft noise around smaller city airports  

NASA Technical Reports Server (NTRS)

The results are presented of a study of community reaction to jet aircraft noise in the vicinity of airports in Chattanooga, Tennessee, and Reno, Nevada. These cities were surveyed in order to obtain data for comparison with that obtained in larger cities during a previous study. (The cities studied earlier were Boston, Chicago, Dallas, Denver, Los Angeles, Miami, and New York.) The purpose of the present effort was to observe the relative reaction under conditions of lower noise exposure and in less highly urbanized areas, and to test the previously developed predictive equation for annoyance under such circumstances. In Chattanooga and Reno a total of 1960 personal interviews based upon questionnaires were obtained. Aircraft noise measurements were made concurrently and aircraft operations logs were maintained for several weeks in each city to permit computation of noise exposures. The survey respondents were chosen randomly from various exposure zones.

Toxic epidermal necrolysis and Stevens-Johnson syndrome.  

PubMed

Toxic epidermal necrolysis (TEN) and Stevens Johnson Syndrome (SJS) are severe adverse cutaneous drug reactions that predominantly involve the skin and mucous membranes. Both are rare, with TEN and SJS affecting approximately 1or 2/1,000,000 annually, and are considered medical emergencies as they are potentially fatal. They are characterized by mucocutaneous tenderness and typically hemorrhagic erosions, erythema and more or less severe epidermal detachment presenting as blisters and areas of denuded skin. Currently, TEN and SJS are considered to be two ends of a spectrum of severe epidermolytic adverse cutaneous drug reactions, differing only by their extent of skin detachment. Drugs are assumed or identified as the main cause of SJS/TEN in most cases, but Mycoplasma pneumoniae and Herpes simplex virus infections are well documented causes alongside rare cases in which the aetiology remains unknown. Several drugs are at "high" risk of inducing TEN/SJS including: Allopurinol, Trimethoprim-sulfamethoxazole and other sulfonamide-antibiotics, aminopenicillins, cephalosporins, quinolones, carbamazepine, phenytoin, phenobarbital and NSAID's of the oxicam-type. Genetic susceptibility to SJS and TEN is likely as exemplified by the strong association observed in Han Chinese between a genetic marker, the human leukocyte antigen HLA-B*1502, and SJS induced by carbamazepine. Diagnosis relies mainly on clinical signs together with the histological analysis of a skin biopsy showing typical full-thickness epidermal necrolysis due to extensive keratinocyte apoptosis. Differential diagnosis includes linear IgA dermatosis and paraneoplastic pemphigus, pemphigus vulgaris and bullous pemphigoid, acute generalized exanthematous pustulosis (AGEP), disseminated fixed bullous drug eruption and staphyloccocal scalded skin syndrome (SSSS). Due to the high risk of mortality, management of patients with SJS/TEN requires rapid diagnosis, evaluation of the prognosis using SCORTEN, identification and interruption of the culprit drug, specialized supportive care ideally in an intensive care unit, and consideration of immunomodulating agents such as high-dose intravenous immunoglobulin therapy. SJS and TEN are severe and life-threatening. The average reported mortality rate of SJS is 1-5%, and of TEN is 25-35%; it can be even higher in elderly patients and those with a large surface area of epidermal detachment. More than 50% of patients surviving TEN suffer from long-term sequelae of the disease. PMID:21162721

TennCare disenrollment and avoidable hospital visits in Davidson County, Tennessee.  

PubMed

The objective of this study was to determine if an association existed between the mid-2005 TennCare (Medicaid) disenrollment and increases in uninsured ambulatory care sensitive condition (ACSC) non-admitted ER visits and inpatient hospitalizations in Davidson County, Tennessee (= the city of Nashville). Logistic regression modeling, using an interactive term for insurance category x year, indicated that the effect of no insurance on ACSC ER visits increased by 18% from 2003 to 2007 (p<.001), but no significant effect was found for uninsured ACSC inpatient hospitalizations. These greater odds of ACSC ER visits among uninsured patients were associated with a 60% increase in hospitals' bad debt write offs during this same time period. Therefore, the TennCare disenrollment was associated with increased likelihood of uninsured ACSC non-admitted ER visits and greater financial losses for Davidson County hospitals during this time period.

Eastern equine encephalitis in Tennessee: 2002-2008.  

PubMed

Human and equine outbreaks caused by eastern equine encephalomyelitis virus (EEEV) typically occur in North America adjacent to coastal wetlands associated with the presence of Culiseta melanura (Coquillet) mosquitoes. Eastern equine encephalomyelitis (EEE) is an emerging disease in Tennessee, as the first records of equine disease began in 2002. In 2006 we trapped and tested mosquitoes for EEEV at hardwood swamps in western Tennessee that were at the epicenter of a multi-equine outbreak in fall of 2005. Additionally, the Tennessee Valley Authority tested mosquito pools collected in Tennessee swamps from 2000 to 2007 for the presence of arboviruses. Two pools of EEEV positive Culex erraticus (Dyer and Knab) mosquitoes were found (one each in 2003 and 2004) in a county adjacent to where the 2005 outbreak occurred. In 2008, another EEE outbreak involving multiple horses occurred in West Tennessee. A brain specimen was collected from a horse during this outbreak and the first isolate of EEEV from Tennessee was obtained. In total, 74,531 mosquitoes collected from 2000 to 2008 were tested via polymerase chain reaction and VecTest for EEEV. The traditional enzootic vector, Cs. melanura, was found in low numbers at all collection sites. Cx. erraticus, however, was consistently found in high numbers and was the only mosquito species in which EEEV was detected. We suggest that EEE transmission may be maintained by Cx. erraticus in a nontraditional cycle. We discuss the importance of a nontraditional cycle from the perspective of EEEV adaptation and emergence. PMID:22679883

Northwestern University's Jerry Goldman, provider of the Oyez Oyez Oyez Supreme Court Oral Arguments audio archive (discussed in the January 26, 1996 Scout Report) has made another net contribution, providing RealAudio versions of telephone conversations of President Lyndon Johnson, recorded on May 27, 1964. Recently released by the LBJ Presidential Library in Austin, Texas, three of the four recordings concern LBJ's misgivings about American involvement in the conflict in Vietnam. The conversations are between Johnson and Adlai Stevenson, McGeorge Bundy, Richard Russell, and George Reedy, and illustrate just how torn the president and some of his advisors were over escalating the war, just a few months before the Tonkin Gulf Resolution that marked the beginning of that escalation. More information on recordings and transcripts of President Johnson's conversations and meetings can be found at the LBJ Presidential Library site.

A posteriori error estimates for the Johnson-N?d?lec FEM-BEM coupling  

PubMed Central

Only very recently, Sayas [The validity of Johnson–Nédélec's BEM-FEM coupling on polygonal interfaces. SIAM J Numer Anal 2009;47:3451–63] proved that the Johnson–Nédélec one-equation approach from [On the coupling of boundary integral and finite element methods. Math Comput 1980;35:1063–79] provides a stable coupling of finite element method (FEM) and boundary element method (BEM). In our work, we now adapt the analytical results for different a posteriori error estimates developed for the symmetric FEM–BEM coupling to the Johnson–Nédélec coupling. More precisely, we analyze the weighted-residual error estimator, the two-level error estimator, and different versions of (h?h/2)-based error estimators. In numerical experiments, we use these estimators to steer h-adaptive algorithms, and compare the effectivity of the different approaches.

Noise Properties in the Ideal Kirchhoff-Law-Johnson-Noise Secure Communication System  

PubMed Central

In this paper we determine the noise properties needed for unconditional security for the ideal Kirchhoff-Law-Johnson-Noise (KLJN) secure key distribution system using simple statistical analysis. It has already been shown using physical laws that resistors and Johnson-like noise sources provide unconditional security. However real implementations use artificial noise generators, therefore it is a question if other kind of noise sources and resistor values could be used as well. We answer this question and in the same time we provide a theoretical basis to analyze real systems as well.

Geographic information system index for the State of Tennessee  

USGS Publications Warehouse

Recently the use of Geographical Information Systems (GIS) has increased within Tennessee. As a result, the U.S. Geological Survey, the Tennessee State Planning Office, and the Tennessee Comptroller of the Treasury entered into an agreement to conduct a survey of GIS users within the State. Two hundred and sixty three agencies were contacted. One hundred and thirty-nine agencies maintained one or more computer system (including personal computers). Twenty-five agencies used GIS software. The number of coverages or layers that exist upon completion of the survey as computerized digital data for Tennessee was 4,741. One hundred and twenty location-specific data bases were available. The U.S. Geological Survey, National Mapping Division map accuracy standards and digital cartographic data standards were included as minimum guidelines for GIS users. General data sharing techniques were described. The most common one was the use of magnetic tapes. A GIS index data base containing the survey data was built for inquiries. A 7.5 minute quadrangle coverage of Tennessee was created to allow for identification on a quadrangle basis of existing coverages contained in the GIS data base. (USGS)

GAINING CONSENSUS: THE STORY OF ''OAK RIDGE TENNESSEE - A CITIZEN'S GUIDE TO THE ENVIRONMENT''  

SciTech Connect

In 2001, a diverse group of citizens ranging from conservationists to industrial developers joined forces to produce a factual description of Oak Ridge's environment and the issues associated with contamination on the U.S. Department of Energy (DOE) reservation. This consensus effort was a result of common values not generally seen in this spectrum of philosophies, and of shared concerns about rising property taxes, declining city services, fleeing retail establishments, and diminishing real estate values. These problems are attributed to waning local DOE budgets coupled with Oak Ridge's national reputation of being contaminated and unsafe. This undeserved reputation harms the city's ability to attract new industry to replace declining federal employment and to induce families to live in the community. Representatives from a spectrum of conservation, environmental, economic development, local government, and civic organizations were invited to meet regarding how to best explain the complex environmental story of Oak Ridge and the DOE reservation. This large group decided to publish a straightforward explanation of the environmental quality of the city and its relationship to the DOE reservation in easy-to-understand language. The result was Oak Ridge, Tennessee--A Citizen's Guide to the Environment, a 28-page glossy booklet, distributed through the Chamber of Commerce and other organizations. The Oak Ridger ensured wide distribution in the community by publishing it as an insert in the daily paper. The material is also available on several web sites. A trifold brochure summarizing and promoting the larger document was also produced for wider distribution. The integrity of the Citizen's Guide was ensured by having a six-member editorial team manage writing and review of the document. There was no direct involvement by the DOE and its contractor. Knowledgeable citizen writers from throughout the community contributed technical and descriptive text. A professional technical editor melded the disparate styles into a cohesive publication. Volunteers from about 100 organizations reviewed the draft for accuracy of content and readability. Participating organizations, upon review of the final draft, then decided whether their names would be listed in the document as contributors and supporters. While the writing and editing was primarily accomplished by conservation and civic organizations, funding to print the final publications came largely from economic development interests and their supporters. The positive reception from the public upon release of Oak Ridge, Tennessee--A Citizen's Guide to the Environment stands as testament to the ability of diverse interest groups to come to consensus and communicate the environmental value of their community.

Geohydrology of the valley-fill aquifer in the Endicott-Johnson City area, Broome County, New York  

USGS Publications Warehouse

This report is the tenth in a series of 11 map sets depicting geohydrologic conditions in selected aquifers in upstate New York. Geohydrologic data are compiled on five maps at 1:24,000 scale. Together, the maps provide a comprehensive overview of a major valley-fill aquifer in southwestern Broome County. The maps include surficial geology, geologic sections, aquifer thickness, water-infiltration potential of soil zone, potentiometric-surface altitude, and land use. The valley-fill deposits consist of alluvial silt and sand, glacial outwash (sand and gravel), ice-contact sand and gravel, till, and lacustrine silt and clay. The sand and gravel beds have relatively high permeabilities whereas the till, silt, and clay deposits have relatively low permeabilities. Water-table conditions are found in unconfined sand and gravel, whereas artesian conditions prevail within sand and gravel confined by silty deposits. Recharge occurs over the entire surface of the aquifer, due to permeable land-surface conditions, but is greatest along the margin of the valley, where runoff from the hillsides is concentrated, and near streams. The use of land overlying the aquifer is predominantly commercial and residential with lesser amounts of agricultural and industrial uses. (USGS)

Early-stage evolution of particle size distribution with Johnson's SB function due to Brownian coagulation  

NASA Astrophysics Data System (ADS)

The moment method can be used to determine the time evolution of particle size distribution due to Brownian coagulation based on the general dynamic equation (GDE). But the function form of the initial particle size distribution must be determined beforehand for the moment method. If the assumed function type of the initial particle size distribution has an obvious deviation from the true particle population, the evolution of particle size distribution may be different from the real evolution tendency. Thus, a simple and general method is proposed based on the moment method. In this method, the Johnson's SB function is chosen as a general distribution function to fit the initial distributions including the log normal (L-N), Rosin-Rammler (R-R), normal (N-N) and gamma distribution functions, respectively. Meanwhile, using the modified beta function to fit the L-N, R-R, N-N and gamma functions is also conducted as a comparison in order to present the advantage of the Johnson's SB function as the general distribution function. And then, the time evolution of particle size distributions using the Johnson's SB function as the initial distribution can be obtained by several lower order moment equations of the Johnson's SB function in conjunction with the GDE during the Brownian coagulation process. Simulation experiments indicate that fairly reasonable results of the time evolution of particle size distribution can be obtained with this proposed method in the free molecule regime, transition regime and continuum plus near continuum regime, respectively, at the early time stage of evolution. The Johnson's SB function has the ability of describing the early time evolution of different initial particle size distributions.

Addendum to the East Tennessee Technology Park Site-Wide Residual Contamination Remedial Investigation Work Plan Oak Ridge, Tennessee  

SciTech Connect

The East Tennessee Technology Park Site-Wide Residual Contamination Remedial Investigation Work Plan (DOE 2004) describes the planned fieldwork to support the remedial investigation (RI) for residual contamination at the East Tennessee Technology Park (ETTP) not addressed in previous Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (CERCLA) decisions. This Addendum describes activities that will be conducted to gather additional information in Zone 1 of the ETTP for groundwater, surface water, and sediments. This Addendum has been developed from agreements reached in meetings held on June 23, 2010, August 25, 2010, October 13, 2010, November 13, 2010, December 1, 2010, and January 13, 2011, with representatives of the U. S. Department of Energy (DOE), U. S. Environmental Protection Agency (EPA), and Tennessee Department of Environment and Conservation (TDEC). Based on historical to recent groundwater data for ETTP and the previously completed Sitewide Remedial Investigation for the ETTP (DOE 2007a), the following six areas of concern have been identified that exhibit groundwater contamination downgradient of these areas above state of Tennessee and EPA drinking water maximum contaminant levels (MCLs): (1) K-720 Fly Ash Pile, (2) K-770 Scrap Yard, (3) Duct Island, (4) K-1085 Firehouse Burn/J.A. Jones Maintenance Area, (5) Contractor's Spoil Area (CSA), and (6) Former K-1070-A Burial Ground. The paper presents a brief summary of the history of the areas, the general conceptual models for the observed groundwater contamination, and the data gaps identified.

Ground-water storage in the Johnson Valley area, San Bernardino, California  

USGS Publications Warehouse

The Mojave Water Agency includes several desert basins where ground water in storage is many times as great as the average annual recharge. The Johnson Valley area in San Bernardino County, Calif., was evaluated for (1) the quantity of ground water in storage, (2) the chemical quality of the ground water, and (3) the potential for storage of recharge water in the unsaturated zone. Johnson Valley contains about 250,000 acre-feet of water in storage, of which about half can be considered recoverable. About 250,000 acre-feet of void space in the unsaturated alluvium is available for storage of imported water, but not all of the recharged water could be recovered. The quality of the water in storage is satisfactory for public consumption, although water from some areas has high floride concentrations and should be mixed with water of low fluoride concentration.

FEMP case study: Regional super ESPC saves energy and dollars at NASA Johnson Space Center  

SciTech Connect

This case study describes the new energy-efficient equipment being installed at NASA Johnson Space Center in Houston, Texas, to save nearly $2 million per year in energy and utility costs. The work is being done under a delivery order by Honeywell, Inc., as part of a US Department of Energy ``super'' regional energy savings performance contract, or Super ESPC. These are streamlined contracts that allow Federal agencies to contract with competitively selected energy service companies in their region for a variety of energy- and water-efficient products and services. The service companies pay up-front capital costs and are reimbursed with part of the agency's utility cost savings. In this work, NASA Johnson Space Center will get new energy-efficient lighting and compressed-air systems, water-conserving fixtures, and improved controls.

A Fifty-Year Love Affair with Organic Chemistry (by William S. Johnson)  

NASA Astrophysics Data System (ADS)

This latest volume is the 20th in Jeff Seeman's projected 22-volume series of autobiographies of 20th-century organic chemists that began publication in 1990 (Kauffman, G. B. J. Chem. Educ. 1991, 68, A21). Unfortunately, Johnson did not live to see this volume in print. Ted Bartlett and Ray Conrow reviewed the final manuscript, galleys, and page proofs; and Ted Bartlett, Paul Bartlett, John D. Roberts, and Gilbert Stork contributed an epilogue that complements Johnson's own words, adds a warm, personal final touch that he was unable to provide, and incorporates his final research into the volume. Born in New Rochelle, New York, on February 24, 1913, William Summer Johnson attended Amherst College with the aid of a scholarship and various odd jobs such as tending furnace, washing dishes, and playing saxophone in dance bands (he seriously considered becoming a professional musician). Here he became enamored with organic chemistry, which he taught as an instructor for a year after his graduation magna cum laude in 1936. He then worked with a fellowship under Louis Fieser, who sparked his interest in steroids, at Harvard University, from which he received his M.A. (1938) and Ph.D. (1940) degrees. In 1940 Johnson joined the faculty at the University of Wisconsin, where he rose through the ranks, eventually becoming Homer Adkins Professor of Chemistry (1954-60). He began the total synthesis of steroids, the main subject of his life's work, "which soon proved to be the hottest synthetic target of the time". In 1960 he accepted an invitation to become head of and to upgrade the Stanford University Chemistry Department. With faculty recruiting as his primary concern, he was able to add Carl Djerassi, Paul J. Flory, Harden M. McConnell, Henry Taube, and Eugene E. van Tamelen to the department, resulting in its spectacular rise from 15th to 5th place in the nation. He remained at Stanford for the rest of his career, serving as department head for nine years. He died at the age of 82 on August 19, 1995. Johnson's book reads like a Who's Who of Organic Chemistry, with descriptions, impressions, and thumbnail sketches of such luminaries as Sir Robert Robinson, Robert B. Woodward, Gilbert Stork, Carl Djerassi, Derek Barton, John D. ("Jack") Roberts, and authors of other Profiles volumes. During his long and productive career, Johnson made many contributions to contemporary organic chemistry, the genesis and course of which he describes lucidly with extensive use of 110 structural formulas, 75 reaction schemes, and occasional laboratory notebook pages. Three hundred fifty-six graduate and undergraduate students, postdocs, and visiting professors (many of whom are shown in the 63 formal and informal photographs in the book) have worked with him through five and a half decades. In "Some Concluding Remarks about Our Research", Johnson states, "The reviewed research did not evolve from a master plan; indeed it was largely a matter of following one's nose and trying to look at things that related to areas that were regarded as important issues of the time." Johnson's intimate and revealing autobiography will not only appeal to synthetic organic chemists but will be of interest to both present and future generations of students and instructors of chemistry courses and the history of science as well as to all persons concerned with the human aspects of science.

Stevens-Johnson syndrome: report on a case with a strange complaint of allergy to bus.  

PubMed

Stevens-Johnson syndrome is an uncommon inflammatory skin disorder in which immune mechanisms, cytotoxic reactions, and delayed hypersensitivity seem to be involved. Herein, an unusual case with strange complaint of"bus allergy" is presented, suffering from severe generalized itching and skin lesions, followed by ulcers in his mouth and genitalia. The diagnosis of Stevens-Johnson syndrome was made and appropriate treatment was advised. However, detailed medical history revealed a completely different cause of his allergic reactions, as he had occasionally used dimenhydrinate because of motion sickness in his history. Therefore, adverse drug reaction to dimenhydrinate was considered as the main underlying cause of the disease. In conclusion, thorough medical history should be taken to make a definitive diagnosis and identify the underlying disease, since accurate diagnosis and appropriate treatment can prevent further complications.

Bottom-Sediment Accumulation and Quality in Shawnee Mission Lake, Johnson County, Kansas, 2006  

USGS Publications Warehouse

Shawnee Mission Lake is an artificial impoundment central to Shawnee Mission Park, the largest public park in Johnson County, Kansas. The Shawnee Mission Lake watershed has remained relatively undeveloped since the completion of the dam in 1962. However, recent (1990?2006) urban development has been a cause for concern regarding the quantity and quality of sediment entering the reservoir. The U.S. Geological Survey collected two cores of bottom sediment to assess sediment accumulation and quality in Shawnee Mission Lake. Results from this study indicate that sediment accumulation has remained relatively constant from 1970?2006 at the downstream portion of the reservoir. Runoff from urban portions of the watershed are likely responsible for larger concentrations of selected trace elements in more recently deposited reservoir sediment. Information provided in this report can be used by Johnson County officials to help determine the current and future recreational capacity of the lake.

Electronic measurement of the Boltzmann constant with a quantum-voltage-calibrated Johnson noise thermometer  

NASA Astrophysics Data System (ADS)

Currently, the CODATA value of the Boltzmann constant is dominated by a single gas-based thermometry measurement with a relative standard uncertainty of 1.8×10 [P.J. Mohr, B.N. Taylor, D.B. Newell, CODATA recommended values of the fundamental physical constants: 2006, Rev. Mod. Phys. 80 (2008) 633-730]. This article describes an electronic approach to measuring the Boltzmann constant that compares Johnson noise from a resistor at the water triple point with a pseudo-random noise generated using quantized ac-voltage synthesis. Measurement of the ratio of the two power spectral densities links Boltzmann's constant to Planck's constant. Recent experiments and detailed uncertainty analysis indicate that Boltzmann's constant can presently be determined using Johnson noise with a relative standard uncertainty below 10×10, which would support both historic and new determinations.

A Ratiometric Method for Johnson Noise Thermometry Using a Quantized Voltage Noise Source  

NASA Astrophysics Data System (ADS)

Johnson Noise Thermometry (JNT) involves the measurement of the statistical variance of a fluctuating voltage across a resistor in thermal equilibrium. Modern digital techniques make it now possible to perform many functions required for JNT in highly efficient and predictable ways. We describe the operational characteristics of a prototype JNT system which uses digital signal processing for filtering, real-time spectral cross-correlation for noise power measurement, and a digitally synthesized Quantized Voltage Noise Source (QVNS) as an AC voltage reference. The QVNS emulates noise with a constant spectral density that is stable, programmable, and calculable in terms of known parameters using digital synthesis techniques. Changes in analog gain are accounted for by alternating the inputs between the Johnson noise sensor and the QVNS. The Johnson noise power at a known temperature is first balanced with a synthesized noise power from the QVNS. The process is then repeated by balancing the noise power from the same resistor at an unknown temperature. When the two noise power ratios are combined, a thermodynamic temperature is derived using the ratio of the two QVNS spectral densities. We present preliminary results where the ratio between the gallium triple point and the water triple point is used to demonstrate the accuracy of the measurement system with a standard uncertainty of 0.04 %.

In general, the project found that e-government has made progress in the past year, but privacy, security, and accessibility are still troubled areas. The second report, from the Pew Internet Project (PIP), focuses more closely on community development organizations and their relationship to the Internet. PIP looks at five cities -- Austin, Texas; Cleveland, Ohio; Nashville, Tennessee; Portland, Oregon; and Washington, DC -- and the ways that institutions in these cities are using the Internet to accomplish their goals. In particular, "this research asks whether the Internet is serving as a catalyst to change the 'rules of the game' that shape social capital -- the informal norms and customs that grease the wheels of urban life."

Serum samples from 706 raccoons (Procyon lotor) from 10 counties in the Ridge and Valley and Blue Ridge Mountains ecoregions of eastern Tennessee were tested for antibodies reactive with T. cruzi using the indirect fluorescent antibody assay. Two hundred six (29.2%) samples were seropositive, with 9 counties yielding positive samples (range 14.6-63.6%). Significantly more raccoons from rural habitats (35.1%) were found positive for T. cruzi exposure than were those from suburban habitats (23.1%, P < 0.001). Land cover class was not associated with seropositivity status (P = 0.441), even though deciduous forest was the most common site from where raccoons were trapped and the most common site of positive raccoons in rural areas (42%). Interestingly, age was positively associated with seropositivity. Raccoons older than 1 yr (adults) were 40.1% seropositive compared to 12.2% of those less than 1 yr (juveniles; P < 0.001). Female adults were significantly more likely to be exposed to T. cruzi than were male adult raccoons (P < 0.001). No significant seroprevalence difference was seen among male and female juveniles. This study contributes to understanding the dynamics of T. cruzi exposure within raccoon populations in Tennessee. The importance of habitat (rural vs. suburban) and microhabitat (dens) in risk of exposure to these populations is also discussed. PMID:20001097

Technique for estimating depth of 100-year floods in Tennessee  

USGS Publications Warehouse

Preface: A method is presented for estimating the depth of the loo-year flood in four hydrologic areas in Tennessee. Depths at 151 gaging stations on streams that were not significantly affected by man made changes were related to basin characteristics by multiple regression techniques. Equations derived from the analysis can be used to estimate the depth of the loo-year flood if the size of the drainage basin is known.

Synthesized flood frequency for small urban streams in Tennessee  

USGS Publications Warehouse

Bridge, culvert, and highway design often require knowledge of the magnitude and frequency of flood discharge from small streams where the drainage basin is urbanized. The results of a 6-year study by the U.S. Geological Survey provide methods for estimating flood magnitudes for selected frequencies on small streams draining urban areas in Tennessee. A total of 22 rainfall-runoff sites located in basins with drainage areas of 0.21 to 24.3 square miles in size and in municipalities with populations between 5,000 and 100,000 were used to derive regionalized flood-frequency equations. Impervious area, measured from recent aerial photographs, ranged between 4.7 percent and 74.0 percent of the basin. The equations were derived by multiple regression analyses of snythetic flood-frequency estimates, derived from a rainfall-runoff modeling procedure, versus physical basin characteristics and a precipitation factor. These equations can be used to estimate the magnitude of future floods with recurrence intervals of 2 to 100 years on ungaged urbanized streams in Tennessee. One equation for each recurrence interval applies statewide. Flood-frequency estimates for stations used in the analyses and example computations demonstrating applications of the regression equations to urban streams in Tennessee are given in the report.

Indoor pollutants in 70 houses in the Tennessee Valley Area: study design and measurement methods  

SciTech Connect

Levels of nitrogen dioxide, formaldehyde, vapor-phase polynuclear aromatic hydrocarbon compounds, respirable particles, radon and other parameters related to indoor air quality are being measured with passive monitors in a year-long study of indoor air quality in 70 houses in the Tennessee Valley area. Criteria for house selection included presence of a lower level with cement floor and one or more block walls in contact with the soil and proximity to one of four cities in the region (Knoxville, Chattanooga, Birmingham, and Florence). By design, most of the houses in the study are in the same neighborhood as at least one other house in the study. Houses range in age from newly constructed to about forty years old, typically have more than 2000 square feet of finished floor space, and encompass a garage in the lower level in most cases. Six houses near Knoxville were especially selected for intensive study. An instrumented measurement and data acquisition system were used during the summer of 1985 to make a nearly continuous record of oxides of nitrogen, oxides of carbon, formaldehyde, particulate matter, ozone, air exchange rate, and air movement. Simultaneously, passive monitors identical to those used throughout the study were deployed with increased replication in the houses.

A survey of health needs of older adults in northwest Johnson County, Iowa.  

PubMed

In 1975, the 1972 survey by the DuPage County, Illinois, Health Department (Managan et al. 1974) was replicated in an eight-township area of Johnson County, Iowa, to compare and document areas of nursing needs for the nursing division of a rural health center and to determine if the Illinois findings were generalizable to a setting which included both similarities and differences. The DuPage County population was urban, while the Johnson County population had a strong farm background and the majority of the subjects still resided on a farm. The DuPage County sample of 1,466 represented approximately 5 percent of the elderly population. The sample size in the Johnson County study was only 82; however, it represented approximately 10 percent of the elderly in the eight townships of the study area. The method of interviewing in the resident's homes was replicated as was DuPage's method of statistical analysis. Comparison of data from the two counties showed striking similarities in all parameters: health condition, physical functioning accessibility of medical care, social isolation, and service needs. Both studies found need for additional health services. A multiple disciplinary service approach to health needs would assist the elderly to remain in their own homes longer and to improve the quality of their lives. In the Iowa study, four questions to determine satisfaction with present living facilities and with adequacy of income for needed medical and dental costs were added. When these answers were compared to two previous Iowa studies, findings were similar. PMID:258804

NASA Astrophysics Data System (ADS)

In this paper we present an implementation of the modified Becke-Johnson meta-GGA functional (TB09) in the PWSCF program of Quantum ESPRESSO package via the LIBXC library. Using the functionals of TB09 we calculated the band gaps of some semiconductors and compared the results with previous calculations and experiments. We showed that combining GGA pseudo-potential with TB09 functionals would improve greatly the band gaps compared with the GGA calculations. The details of our implementation and code samples are also given.

We introduce a protocol with a reconfigurable filter system to create non-overlapping single loops in the smart power grid for the realization of the Kirchhoff-Law-Johnson-(like)-Noise secure key distribution system. The protocol is valid for one-dimensional radial networks (chain-like power line) which are typical of the electricity distribution network between the utility and the customer. The speed of the protocol (the number of steps needed) versus grid size is analyzed. When properly generalized, such a system has the potential to achieve unconditionally secure key distribution over the smart power grid of arbitrary geometrical dimensions. PMID:23936164

Errors and Their Mitigation at the Kirchhoff-Law-Johnson-Noise Secure Key Exchange  

PubMed Central

A method to quantify the error probability at the Kirchhoff-law-Johnson-noise (KLJN) secure key exchange is introduced. The types of errors due to statistical inaccuracies in noise voltage measurements are classified and the error probability is calculated. The most interesting finding is that the error probability decays exponentially with the duration of the time window of single bit exchange. The results indicate that it is feasible to have so small error probabilities of the exchanged bits that error correction algorithms are not required. The results are demonstrated with practical considerations.

A new look at the classical key exchange system based on amplified Johnson noise  

NASA Astrophysics Data System (ADS)

A classical key exchange system based on the amplified Johnson noise has been proposed and demonstrated recently. In this Letter, a modified system is presented. By using circulator and feedback, the new system can be compatible with traditional analog and digital communications systems using carrier waves. Results of circuit simulations, however, indicate that the signal transit time poses a serious risk. Because of delay and multiple reflections, there is always a difference between two parties communicating. The eavesdropper can exploit this difference. By choosing impedance and delay time, the difference can be reduced. Nevertheless, the system is far from being secure except when two parties are collocated.

On the security of the Kirchhoff-law-Johnson-noise (KLJN) communicator  

NASA Astrophysics Data System (ADS)

A simple and general proof is given for the information theoretic (unconditional) security of the Kirchhoff-law-Johnson-noise key exchange system under practical conditions. The unconditional security for ideal circumstances, which is based on the second law of thermodynamics, is found to prevail even under slightly non-ideal conditions. This security level is guaranteed by the continuity of functions describing classical physical linear, as well as stable non-linear, systems. Even without privacy amplification, Eve's probability for successful bit guessing is found to converge toward 0.5—i.e., the perfect security level—when ideal conditions are approached.

Pharmacy in a New Frontier - The First Five Years at the Johnson Space Center Pharmacy  

NASA Technical Reports Server (NTRS)

A poster entitled "Space Medicine - A New Role for Clinical Pharmacists" was presented in December 2001 highlighting an up-and-coming role for pharmacists at the Johnson Space Center (JSC) in Houston, Texas. Since that time, the operational need for the pharmacy profession has expanded with the administration s decision to open a pharmacy on site at JSC to complement the care provided by the Flight Medicine and Occupational Medicine Clinics. The JSC Pharmacy is a hybrid of traditional retail and hospital pharmacy and is compliant with the ambulatory care standards set forth by the Joint Commission. The primary charge for the pharmacy is to provide medication management for JSC. In addition to providing ambulatory care for both clinics, the pharmacists also practice space medicine. A pharmacist had been involved in the packing of both the Space Shuttle and International Space Station Medical Kits before the JSC Pharmacy was established; however, the role of the pharmacist in packing medical kits has grown. The pharmacists are now full members of the operations team providing consultation for new drug delivery systems, regulations, and patient safety issues. As the space crews become more international, so does the drug information provided by the pharmacists. This presentation will review the journey of the JSC Pharmacy as it celebrated its five year anniversary in April of 2008. The implementation of the pharmacy, challenges to the incorporation of the pharmacy into an existing health-care system, and the current responsibilities of a pharmacist at the Johnson Space Center will be discussed.

Universal departure from Johnson-Nyquist relation caused by limited resolution  

NASA Astrophysics Data System (ADS)

Exploiting the two-point measurement statistics, we propose a quantum measurement scheme of current with limited resolution of electron counting. Our scheme is equivalent to the full counting statistics in the long-time measurement with the ideal resolution, but is theoretically extended to take into account the resolution limit of actual measurement devices. Applying our scheme to a resonant level model, we show that the limited resolution of current measurement gives rise to a positive excess noise, which leads to a deviation from the Johnson-Nyquist relation. The deviation exhibits universal single-parameter scaling with the scaling variable Q ?SM/S0, which represents the degree of the insufficiency of the resolution. Here, S0 is the intrinsic noise, and SM is the positive quantity that has the same dimension as S0 and is defined solely by the measurement scheme. For the lack of the ideal resolution, the deviation emerges for Q <1 as 2exp[-(2?)2/Q] having an essential singularity at Q =0, which followed by the square root dependence ?Q /4? for Q ?1. Our findings offer an explanation for the anomalous enhancement of noise temperature observed in Johnson noise thermometry.

Systemic lupus erythematosus presenting as stevens-johnson syndrome/toxic epidermal necrolysis.  

PubMed

Stevens-Johnson syndrome (SJS)/toxic epidermal necrolysis (TEN)-like lesions in acute cutaneous lupus erythematosus [LE]) are an unusual manifestation of systemic LE. We describe a patient with widespread vesiculobullous lesions diagnosed as SJS/TEN-like acute cutaneous LE as the initial presentation of systemic LE. Stevens-Johnson syndrome/TEN-like LE may be differentiated from other vesiculobullous lesions by factors including a history of recent LE exacerbation, photodistribution of lesions, lack of a precipitating infection or medication exposure, minimal mucosal involvement, a prolonged course, response steroid treatment, and histologic and immunofluorescence findings. It is paramount to identify SJS/TEN-like LE as this condition requires early and aggressive intervention. The optimal treatment approach for SJS/TEN-like LE is unclear, and although some case reports have shown glucocorticoids to be useful, there are also reports of cases in which additional measures, such as intravenous immunoglobulin and plasmapheresis, were required to achieve a response. Our patient's condition was refractory to high-dose corticosteroids and intravenous immunoglobulin but was successfully treated using plasma exchange. As such, this treatment may hold potential for improving the care of other patients with refractory SJS/TEN-like LE. PMID:24662561

Harnessing the heightened public awareness of celebrity HIV disclosures: "Magic" and "Cookie" Johnson and HIV testing.  

PubMed

This article investigates the impact NBA basketball star Earvin ("Magic") Johnson's HIV disclosure had on changes in demand for HIV counseling and testing services in New York State's 61 Anonymous HIV Counseling and Testing sites. Interrupted time-series analyses were conducted on weekly data from over 34,000 clients seeking anonymous HIV counseling and testing services from January 1991 to June 1992, to determine whether demand for these services changed as a result of the disclosure. Results indicated that immediately following the HIV disclosure, there was a substantial increase in service demand, which transcended all sex, race, age, and most HIV risk-related boundaries. Seven months later, demand had not returned to pre-disclosure levels. The strong impact on females, coupled with additional data analyses in obstetrical settings, suggests that previous research has been too narrow in focus, and that the effect of Johnson's HIV disclosure has been enhanced, in part, by the publicity surrounding his wife and baby. The importance of harnessing the heightened public awareness of celebrity HIV disclosures is discussed. PMID:7646947

One aspect of highway construction that affects the public is the safety of its state roads. There are many factors that affect the safety of a given road. One factor that was focused on in this research was the polish resistance capabilities of aggregates. Several pre-evaluation methods have been used in the laboratory to predict what will happen in a field situation. A new pre-evaluation method was invented that utilized AASHTO T 304 procedure upscaled to accommodate surface bituminous aggregates. This new method, called the Tennessee Terminal Textural Condition Method (T3CM), was approved by Tennessee Department of Transportation to be used as a pre-evaluation method on bituminous surface courses. It was proven to be operator insensitive, repeatable, and an accurate indication of particle shape and texture. Further research was needed to correlate pre-evaluation methods to the current field method, ASTM E 274-85 Locked Wheel Skid Trailer. In this research, twenty-five in-place bituminous projects and eight source evaluations were investigated. The information gathered would further validate the T3CM and find the pre-evaluation method that best predicted the field method. In addition, new sources of aggregates for bituminous surface courses were revealed. The results of this research have shown T3CM to be highly repeatable with an overall coefficient of variation of 0.26% for an eight sample repeatability test. It was the best correlated pre-evaluation method with the locked wheel skid trailer method giving an R2 value of 0.3946 and a Pearson coefficient of 0.710. Being able to predict field performance of aggregates prior to construction is a powerful tool capable of saving time, money, labor, and possibly lives.

Low flows and flow duration of Tennessee streams through 1981  

USGS Publications Warehouse

Estimates of low-flow characteristics and flow duration for the period of record at continuous-record streamflow gages are essential in hydrologic studies and water-resources management. This report provides estimates of low flow for 1, 3, 7, 14, 30, 60, and 90 consecutive days for recurrence intervals of 2, 5, 10 , and 20 years for continuous-record streamflow gages in Tennessee. These estimates were used in correlation methods to estimate low flow at partial-record streamflow sites for 1, 3, and 7 consecutive days for a recurrence interval of 10 years; and 3 consecutive days for a recurrence interval of 20 years.

Technique for estimating depth of floods in Tennessee  

USGS Publications Warehouse

Estimates of flood depths are needed for design of roadways across flood plains and for other types of construction along streams. Equations for estimating flood depths in Tennessee were derived using data for 150 gaging stations. The equations are based on drainage basin size and can be used to estimate depths of the 10-year and 100-year floods for four hydrologic areas. A method also was developed for estimating depth of floods having recurrence intervals between 10 and 100 years. Standard errors range from 22 to 30 percent for the 10-year depth equations and from 23 to 30 percent for the 100-year depth equations. (USGS)

Phosphorus Retention Models for Tennessee Valley Authority Reservoirs  

NASA Astrophysics Data System (ADS)

Data for the 18 largest Tennessee Valley Authority (TVA) reservoirs are compared with previously developed models for predicting steady state phosphorus concentrations in lakes. A plug flow model is presented for lakes and reservoirs which have significant longitudinal variation in phosphorus concentration. The results indicate that phosphorus sedimentation and retention coefficients developed for natural lakes are not directly applicable to TVA reservoirs. The apparent settling velocity of phosphorus in TVA reservoirs was substantially higher than previously reported values for natural lakes. Application of the plug flow model to Cherokee Reservoir showed good agreement with measured in-lake phosphorus concentrations.

International Space Station Aeromedical Support in Star City, Russia  

NASA Technical Reports Server (NTRS)

The Space Medicine Division at Johnson Space Center works with the International Space Station s international partners (IP) to accomplish assigned health care tasks. Each IP may assign a flight surgeon to support their assigned crewmembers during all phases of training, in-flight operations, and postflight activities. Because of the extensive amount of astronaut training conducted in Star City; NASA, in collaboration with its IPs, has elected to keep a flight surgeon assigned to NASA s Star City office to provide support to the U.S., Canadian, Japanese, and European astronauts during hazardous training activities and provide support for any contingency landings of Soyuz spacecraft in Kazakhstan. The physician also provides support as necessary to the Mission Control Center in Moscow for non-Russian crew-related activities. In addition, the physician in Star City provides ambulatory medical care to the non-Russian-assigned personnel in Star City and visiting dependents. Additional work involves all medical supplies, administration, and inventory. The Star City physician assists in medical evacuation and/or in obtaining support from western clinics in Moscow when required care exceeds local resources. Overall, the Russians are responsible for operations and the medical care of the entire crew when training in Star City and during launch/landing operations. However, they allow international partner flight surgeons to care for their crewmembers as agreed to in the ISS Medical Operations Requirements Document. Medical support focuses on pressurized, monitored, and other hazardous training activities. One of the most important jobs is to act as a medical advocate for the astronauts and to reduce the threat that these hazardous activities pose. Although the Russians have a robust medical system, evacuation may be needed to facilitate ongoing medical care. There are several international medical evacuation companies that provide this care.

Indoor nitrogen dioxide in five Chattangooga, Tennessee public housing developments  

SciTech Connect

This report summarizes an indoor nitrogen dioxide (NO{sub 2}) sampling study conducted during January through March of 1987 in five Chattanooga public housing developments. The origins of this study date to the summer of 1983 when the Piney Woods Community Organization (a citizens action group) expressed concern about toxic industrial air pollution and the effects it might have on their community. In response to these concerns, the Chattanooga-Hamilton County Air Pollution Control Bureau (Bureau) requested assistance from the Tennessee Department of Health and Environment (TDHE) in conducting a community health survey and assistance from the Tennessee Valley Authority (TVA) in conducting a community air quality measurement program. The TDHE community health study did not find any significant differences between the mortality statistics for the Piney Woods community and a demographically similar control group. However, a health survey revealed that Piney Woods residents did not have a statistically significant higher self-reported prevalence of cough, wheezing, phlegm, breathlessness, colds, and respiratory illness.

Urolithiasis in Tennessee: an occupational window into a regional problem.  

PubMed Central

BACKGROUND: Urinary tract stones (stones) are believed to be unusually common in the southeastern United States but neither the incidence of nor the risk factors for stones are known. METHODS: In three well-defined occupational populations in eastern Tennessee, we assessed the prevalence, incidence, and cumulative incidence of stones and measured biochemical risk factors for lithogenesis. RESULTS: The age-adjusted prevalence of stones was 18.5 percent in Tennessee compared to 7.7 percent among White males in US NHANES (prevalence ratio 2.4, 95% CI 1.7, 3.3). The cumulative incidence (risk) was 27.8 percent by age 65, higher than in any other reported population. Risk factors were age, a family history, and urinary saturation with calcium-oxalate (COAX). Persons with a positive family history and the highest measured CAOX index had a predicted lifetime risk of 88.8 percent. Biochemical factors affecting lithogenesis were hypercalciuria, hyperoxaluria, and low urine volume. CONCLUSION: Future research should characterize the geographic boundaries of a southeastern "stone-belt" and explore genetic and dietary hypotheses that might explain it.

Tennessee gas field brings Eastern Overthrust new life  

SciTech Connect

The Eastern US Overthrust Belt has gained an E and P company in its southern reaches while seeing de-emphasis from a long time player in more northerly areas. A gas field discovered in the early 1980s in northeastern Tennessee is nearly ready to be placed on production. It would be the first commercial gas production in the southern portion of the belt, which extends more than 1,000 miles from Alabama to New England. Tengasco has five wells capable of producing gas from Cambro-Ordovician Knox in Swan Creek field, southwest of Sneedville in Hancock County, Tenn., about 10 miles south of Lee County, Va. It hopes to drill five more wells by year-end. It began laying a 30--35 MMcfd, 23 mile, 6 in. gas pipeline to Rogersville, Tenn., early last month. Torch Inc., Belle Chasse, La., has the contract. Tengasco plans to start production later this year. Initially a gas utility in neighboring Hawkins County will take 8--9 MMcfd and transport any excess gas to Tenneco Energy affiliate East Tennessee Natural Gas Co. The primary production to date in Swan Creek field has been in a 300 ft section some 400--450 ft from the top of Knox. No water has been found.

The Tennessee Mouse Genome Consortium: Identification of ocular mutants  

SciTech Connect

The Tennessee Mouse Genome Consortium (TMGC) is in its fifth year of a ethylnitrosourea (ENU)-based mutagenesis screen to detect recessive mutations that affect the eye and brain. Each pedigree is tested by various phenotyping domains including the eye, neurohistology, behavior, aging, ethanol, drug, social behavior, auditory, and epilepsy domains. The utilization of a highly efficient breeding protocol and coordination of various universities across Tennessee makes it possible for mice with ENU-induced mutations to be evaluated by nine distinct phenotyping domains within this large-scale project known as the TMGC. Our goal is to create mutant lines that model human diseases and disease syndromes and to make the mutant mice available to the scientific research community. Within the eye domain, mice are screened for anterior and posterior segment abnormalities using slit-lamp biomicroscopy, indirect ophthalmoscopy, fundus photography, eye weight, histology, and immunohistochemistry. As of January 2005, we have screened 958 pedigrees and 4800 mice, excluding those used in mapping studies. We have thus far identified seven pedigrees with primary ocular abnormalities. Six of the mutant pedigrees have retinal or subretinal aberrations, while the remaining pedigree presents with an abnormal eye size. Continued characterization of these mutant mice should in most cases lead to the identification of the mutated gene, as well as provide insight into the function of each gene. Mice from each of these pedigrees of mutant mice are available for distribution to researchers for independent study.

Effects of Projected Transient Changes in Climate on Tennessee Forests  

SciTech Connect

This study examines transient effects of projected climate change on the structure and species composition of forests in Tennessee. The climate change scenarios for 2030 and 2080 were provided by the National Center for Atmospheric Research (NCAR) from three General Circulation Models (GCMs) that simulate the range of potential climate conditions for the state. The precipitation and temperature projections from the three GCMs for 2030 and 2080 were related to changes in the ecoregions by using the monthly record of temperature and precipitation from 1980 to 1997 for each 1 km cell across the state as aggregated into the five ecological provinces. Temperatures are projected to increase in all ecological provinces in all months for all three GCMs for both 2030 and 2080. Precipitation patterns are more complex with one model projecting wetter summers and two models projecting drier summers. The forest ecosystem model LINKAGES was used to simulate conditions in forest stands for the five ecological provinces of Tennessee from 1989 to 2300. These model runs suggest there will be a change in tree diversity and species composition in all ecological provinces with the greatest changes occurring in the Southern Mixed Forest province. Most projections show a decline in total tree biomass followed by recovery as species replacement occurs in stands. The changes in forest biomass and composition, as simulated in this study, are likely to have implications on forest economy, tourism, understory conditions, wildlife habitat, mast provisioning, and other services provided by forest systems.

Salt Lake City, Utah, will host the 2002 Winter Olympic Games. The city is located on the southeastern shore of the Great Salt Lake and sits to the west of the Wasatch Mountains, which rise more than 3,500 meters (10,000 feet) above sea level. The city was first settled in 1847 by pioneers seeking relief from religious persecution. Today Salt Lake City, the capital of Utah, is home to more than 170,000 residents. This true-color image of Salt Lake City was acquired by the Enhanced Thematic Mapper Plus (ETM+), flying aboard Landsat 7, on May 26, 2000. The southeastern tip of the Great Salt Lake is visible in the upper left of the image. The furrowed green and brown landscape running north-south is a portion of the Wasatch Mountains, some of which are snow-capped (white pixels). The greyish pixels in the center of the image show the developed areas of the city. A number of water reservoirs can be seen east of the mountain range. Salt Lake City International Airport is visible on the northwestern edge of the city. About 20 miles south of the airport is the Bingham Canyon Copper Mine (tan pixels), the world's largest open pit excavation. See also this MODIS image of Utah.

Lead Paint Exposure Assessment in High Bays of Johnson Space Center  

NASA Technical Reports Server (NTRS)

This slide presentation reviews the program to assess the possibility of lead paint exposure in the high bays of some of the Johnson Space Center buildings. Some of the buildings in the Manned Space Flight Center (MSC) were built in 1962 and predate any considerations to reduce lead in paints and coatings. There are many of these older buildings that contain open shops and work areas that have open ceilings, These shops include those that had operations that use leaded gasoline, batteries, and lead based paints. Test were planned to be conducted in three phases: (1) Surface Dust sampling, (2) personal exposure montioring, and (3) Ceiling paint Sampling. The results of the first two phases were reviewed. After considering the results of the first two phases, and the problems associated with the retrieval of samples from high ceilings, it was determined that the evaluation of ceiling coatings would be done on a project by project and in response to a complaint.

Reactivation of Cytomegalovirus in a Patient with Stevens-Johnson Syndrome-Toxic Epidermal Necrolysis  

PubMed Central

Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are severe adverse cutaneous reactions to drugs. We describe the case of a 19 year old patient with SJS/TEN overlap syndrome, who developed severe interstitial pneumonia after she had received antiepileptic drugs. A cytomegalovirus infection was diagnosed by Real Time Polymerase Chain Reaction (RT-PCR) detection on Bronchoalveolar lavage. Based on observations on biological data, temporal relationship, and clinical features, it could be inferred that the reactivation of cytomegalovirus with viral replication can predispose a person to TEN-SJS. We discuss here, in the light of the current literature, the probable association between drug-induced SJS-TEN and fulminant reactivation of cytomegalovirus.

Troubleshooting: Chilled water distribution problems at the NASA Johnson Space Center

Various modifications over the years had skirted a problem with low chilled water {Delta}T without solving it. This article examines how discovering the cause could help improve the system`s present level of efficiency. The NASA Johnson Space Center had long had a problem with chilled water (CHW) distribution to the 40 buildings served by the Central CHW plant. originally designed in 1964 for a 16 F temperature drop across the central plant chillers, the chilled water system could only attain a 7 F {Delta}T on average and a 10 F {Delta}T at best. This meant not only that twice as much CHW as originally intended had to be pumped around the 5 mile campus loop to satisfy the cooling load but also that the seven 2,000-ton chillers in the central plant couldn`t be loaded much beyond half of their capacity.

Abstract Placobdella cryptobranchii (Johnson & Klemm, 1977) was originally described from specimens collected from Ozark Hellbenders (Cryptobranchus alleganiensis bishopi) from the North Fork of the White River in Missouri, U.S.A. Leeches collected during August 2009 to August 2011 from five localities in Missouri (including the type locality) facilitated a redescription and molecular characterization of Placobdella cryptobranchii. Placobdella cryptobranchii has a rusty, reddish-brown dorsum with 2 lateral rows of unpigmented papillae, two unpigmented nuchal bands, unpigmented patches, and pair of four pre-anal papillae. Molecular comparison of CO-I sequence data from Placobdella cryptobranchii revealed a 93–94% similarity to Placobdella ornata and 10–17% difference among other species of Placobdella.

[Severe drug-induced skin reactions : Stevens-Johnson syndrome and toxic epidermal necrolysis].  

PubMed

Stevens-Johnson syndrome (SJS) and Toxic epidermal necrolysis (TEN) are characterized by extensive blistering of the skin and mucosa; they are considered as one disease entity with varying severity. They are rare but potentially life-threatening and accompanied by high mortality. A clear clinical diagnosis is needed to direct specific therapy, but supportive therapy remains most important. In order to identify and withdraw the inducing drug, a very detailed and thorough medication history has to be obtained. Among the highly suspected (strongly associated) agents are allopurinol, antibacterial sulfonamides, non-steroidal anti-inflammatory drugs of the oxicam type, various anti-epileptics and nevaripine. Together they account for more than half of the cases of SJS/TEN. Although a drug is not always the cause, it is considered very like in approximately 75% of cases. Infections have also to be considered as etiologic factors. PMID:24820799

Fitting Johnson SB curve by the method of maximum likelihood to annual maximum daily rainfalls  

NASA Astrophysics Data System (ADS)

A new method of fitting the Johnson SB distribution using maximum likelihood (ML) procedures is described. Commencing with assumed values for the location and scale parameters, estimates of all four parameters are found iteratively. This does not have the disadvantages of the method of moments for which estimates of the higher moments are required and the ambiguities of the method of percentiles in which estimates of parameters depend on the choice of percentiles. Application is made to sequences of annual maximum daily rainfalls in which the kurtosis is low when compared with that corresponding to the theoretical lognormal distribution for the observed skewness. In some cases the ML procedure is not feasible. Problems encountered with ML estimation and inadequacies arising from short samples on the choice of distribution are discussed.

Laser-driven spall experiments in ductile materials in order to characterize Johnson fracture model constants  

NASA Astrophysics Data System (ADS)

We describe laser-driven spall experiments on aluminum, tantalum, steel and gold targets. The free-surface velocity is measured by using a VISAR diagnostic and is compared with numerical simulations at early spallation stage based on the Johnson fracture model. For each material, we first launch one-dimensional simulations with different values of the model parameters and determine the ones which reproduce correctly the experimental data. Then we use two-dimensional simulations to take into account spatial inhomogeneity of the loading pressure over the laser spot. We show non planar ejected spalls which are in agreement with experimental results. We finally study the fragmentation of thin targets and show differences in material behavior for steel in comparison to gold, tantalum and aluminum.

Quality of Streams in Johnson County, Kansas, and Relations to Environmental Variables, 2003-07  

USGS Publications Warehouse

The quality of streams and relations to environmental variables in Johnson County, northeastern Kansas, were evaluated using water, streambed sediment, land use, streamflow, habitat, algal periphyton (benthic algae), and benthic macroinvertebrate data. Water, streambed sediment, and macroinvertebrate samples were collected in March 2007 during base flow at 20 stream sites that represent 11 different watersheds in the county. In addition, algal periphyton samples were collected twice (spring and summer 2007) at one-half of the sites. Environmental data including water and streambed-sediment chemistry data (primarily nutrients, fecal-indicator bacteria, and organic wastewater compounds), land use, streamflow, and habitat data were used in statistical analyses to evaluate relations between biological conditions and variables that may affect them. This report includes an evaluation of water and streambed-sediment chemistry, assessment of habitat conditions, comparison of biological community attributes (such as composition, diversity, and abundance) among sampling sites, placement of sampling sites into impairment categories, evaluation of biological data relative to environmental variables, and evaluation of changes in biological communities and effects of urbanization. This evaluation is useful for understanding factors that affect stream quality, for improving water-quality management programs, and for documenting changing conditions over time. The information will become increasingly important for protecting streams in the future as urbanization continues. Results of this study indicate that the biological quality at nearly all biological sampling sites in Johnson County has some level of impairment. Periphyton taxa generally were indicative of somewhat degraded conditions with small to moderate amounts of organic enrichment. Camp Branch in the Blue River watershed was the only site that met State criteria for full support of aquatic life in 2007. Since 2003, biological quality improved at one rural sampling site, possibly because of changes in wastewater affecting the site, and declined at three urban sites possibly because of the combined effects of ongoing development. Rural streams in the western and southern parts of the county, with land-use conditions similar to those found at the State reference site (Captain Creek), continue to support some organisms normally associated with healthy streams. Several environmental factors contribute to biological indicators of stream quality. The primary factor explaining biological quality at sites in Johnson County was the amount of urbanization upstream in the watershed. Specific conductance of stream water, which is a measure of dissolved solids in water and is determined primarily by the amount of groundwater contributing to streamflow, the amount of urbanization, and discharges from wastewater and industrial sites, was strongly negatively correlated with biological stream quality as indicated by macroinvertebrate metrics. Concentration of polycyclic aromatic hydrocarbons (PAHs) in streambed sediment also was negatively correlated with biological stream quality. Individual habitat variables that most commonly were positively correlated with biological indicators included stream sinuosity, buffer length, and substrate cover diversity. Riffle substrate embeddedness and sediment deposition commonly were negatively correlated with favorable metric scores. Statistical analysis indicated that specific conductance, impervious surface area (a measure of urbanization), and stream sinuosity explained 85 percent of the variance in macroinvertebrate communities. Management practices affecting environmental variables that appear to be most important for Johnson County streams include protection of stream corridors, measures that reduce the effects of impervious surfaces associated with urbanization, reduction of dissolved solids in stream water, reduction of PAHs entering streams and

Crystallization kinetics of lithium niobate glass: determination of the Johnson-Mehl-Avrami-Kolmogorov parameters.  

PubMed

The formation of crystalline LiNbO3 (LN) from LN glass has been studied by means of differential scanning calorimetry and in situ synchrotron X-ray diffraction. The LN glass with no glass former was prepared by the polymerized complex method. The isothermal kinetics of the crystallization process is described using the Johnson-Mehl-Avrami-Kolmogorov (JMAK) equation and the Avrami exponent n is found to be ~2.0, indicating that the crystallization mechanism is diffusion-controlled growth with a decreasing nucleation rate. The effective activation energy of crystallization calculated from isothermal measurements is 6.51 eV. It is found that the LN glass directly transforms into a rhombohedral LN crystal without any intermediate crystalline phase and most crystal grains are confined within the size of ~40 nm irrespective of different isothermal temperatures. Application of JMAK theory to the non-isothermal thermoanalytical study of crystallization of LN glass is discussed. PMID:23677338

Development of the advanced life support Systems Integration Research Facility at NASA's Johnson Space Center  

NASA Technical Reports Server (NTRS)

Future NASA manned missions to the moon and Mars will require development of robust regenerative life support system technologies which offer high reliability and minimal resupply. To support the development of such systems, early ground-based test facilities will be required to demonstrate integrated, long-duration performance of candidate regenerative air revitalization, water recovery, and thermal management systems. The advanced life support Systems Integration Research Facility (SIRF) is one such test facility currently being developed at NASA's Johnson Space Center. The SIRF, when completed, will accommodate unmanned and subsequently manned integrated testing of advanced regenerative life support technologies at ambient and reduced atmospheric pressures. This paper provides an overview of the SIRF project, a top-level description of test facilities to support the project, conceptual illustrations of integrated test article configurations for each of the three SIRF systems, and a phased project schedule denoting projected activities and milestones through the next several years.

A review of causes of Stevens-Johnson syndrome and toxic epidermal necrolysis in children.  

PubMed

Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are rare life-threatening conditions almost exclusively attributed to drugs. The incidence in children is lower than in adults and has a better outcome. Mycosplama pneumoniae infection may be involved in some cases of paediatric SJS. The main etiologic factors for both SSJ and TEN are sulphonamides and anticonvulsants, followed by penicillins and non-steroidal anti-inflammatory drugs. In rare instances, paracetamol is the only suspected drug. By contrast with adults, allopurinol, oxicams and nevirapine are not identified as causative agents in children, probably due to differences in drug prescriptions. The only aspects of treatment that have been proved to improve survival are the rapid withdrawal of the suspected offending drugs and an optimal supportive therapy with emphasis in nutritional support, accompanied by management of denuded skin areas. The use of specific therapies remains controversial. PMID:23873883

Calibrating the Johnson-Holmquist Ceramic Model for SiC using CTH  

NASA Astrophysics Data System (ADS)

The Johnson-Holmquist ceramic material model has been calibrated and successfully applied to numerically simulate ballistic events using the Lagrangian code EPIC. While the majority of the constants are ``physics'' based, two of the constants for the failed material response are calibrated using ballistic experiments conducted on a confined cylindrical ceramic target. The maximum strength of the failed ceramic is calibrated by matching the penetration velocity. The second refers to the equivalent plastic strain at failure under constant pressure and is calibrated using the dwell time. Use of these two constants in the CTH Eulerian hydrocode does not predict the ballistic response. This difference may be due to the phenomenological nature of the model and the different numerical schemes used by the codes. This paper determines the afore mentioned material constants for SiC suitable for simulating ballistic events using CTH.

Johnson-Cook Strength Model Constants for VascoMax 300 and 1080 Steels  

NASA Astrophysics Data System (ADS)

High strength steels, VascoMax 300 and 1080, are characterized under tension at strain rates of ~1/s, ~500/s, ~1000/s, and ~1500/s and at high temperatures using the quasi-static and split Hopkinson bar techniques. The data on 1080 steel exhibited a typical strain hardening response, whereas Vasco-Max 300 steel showed diminishing flow stress beyond yielding because of localized necking in gauge section of the tested specimens. The tension data are analyzed to determine the Johnson-Cook (J-C) strength model constants for the two steels. The flow stress values for VascoMax are adjusted to account for necking, and the corrected J-C model is developed.

Evaluation of Johnson-Cook model constants for aluminum based particulate metal matrix composites  

NASA Astrophysics Data System (ADS)

High strain rate and high temperature response of three types of aluminum based particulate metal matrix ceramic composites is investigated by performing split Hopkinson pressure bar (SHPB) experiments. The composites are: NGP-2014 (15% SiC), NGT-6061 (15% SiC), and NGU-6061 (15% Al2O3), in which all the reinforcement materials are percentage by volume. Johnson-Cook constitutive model constants are evaluated from the high strain rate/high temperature data and implemented in a two dimensional finite element computer code (EPIC-2D) to simulate the penetration of an ogive nose tungsten projectile (23 grams) at a velocity 1.17 km/sec into the base 6061-T6 aluminum alloy and the composite NGU-6061. The simulated penetrations in the composite and in 6061-T6 aluminum agree with in 2%, in both materials, with the measured values.

Exploring a Model of Symbolic Social Communication: The Case of 'Magic' Johnson  

PubMed Central

We propose a model of symbolic social communication to explain the process whereby sociocultural identity mediates relationships among receivers, sources and messages to shape message effects. This exploratory study examines how two at-risk groups of African American men responded to various HIV prevention messages delivered by celebrity and professional sources. We interviewed 47 men from a homeless shelter and 50 male college students. Members of both groups were likely to select Johnson as the best person to deliver HIV prevention messages among a list of African American celebrity and professional sources. Results suggest the symbolic meanings embedded in celebrities and message topics are important and enduring influences on message effects. The images and ideas that a source represents are transferred to the advocated behavior, attitude or knowledge change and thus shape how messages are interpreted and received. Further understanding of how culture influences the effects of persuasive messages is critical for the improvement of health-communication campaigns.

Holocene ethnobotanical and paleoecological record of human impact on vegetation in the Little Tennessee River Valley, Tennessee  

NASA Astrophysics Data System (ADS)

Human occupation and utilization of plant resources have affected vegetation in the lower Little Tennessee River Valley of East Tennessee for 10,000 yr. Changes in Indian cultures and land use are documented by radiocarbon chronologies, lithic artifacts, ceramics, settlement patterns, and ethnobotanical remains from 25 stratified archaeological sites within the Holocene alluvial terrace. The ethnobotanical record consists of 31,500 fragments (13.7 kg) of wood charcoal identified to species and 7.7 kg of carbonized fruits, seeds, nutshells, and cultigens from 956 features. Pollen and plant macrofossils from small ponds both in the uplands and on lower stream terraces record local vegetational changes through the last 1500 to 3000 yr. Human impact increased after cultigens, including squash and gourd, were introduced ca. 4000 yr B.P. during the Archaic cultural period. Forest clearance and cultivation disturbed vegetation on both the floodplain and lower terraces after 2800 yr B.P., during the Woodland period. Permanent Indian settlements and maize and bean agriculture extended to higher terraces 1.5 km from the floodplain by the Mississippian period (1000 to 300 yr B.P.). After 300 yr B.P., extensive land clearance and cultivation by Historic Overhill Cherokee and Euro-Americans spread into the uplands beyond the river valley.

We present analytic solutions for steady flow of the Johnson–Segalman (JS) model with a diffusion term in various geometries and under controlled strain rate conditions, using matched asymptotic expansions. The diffusion term represents a singular perturbation that lifts the continuous degeneracy of stable, banded, steady states present in the absence of diffusion. We show that the stable steady flow solutions
