    Just as automobiles need fuel to operate, so do nuclear reactors. When fossil fuels such as gasoline are burned to power an automobile, they are consumed immediately and nearly completely in the process. When the fuel is gone, energy production stops. Nuclear reactors are incapable of achieving this near complete burn-up because as the fuel (uranium) that powers them is burned through the process of nuclear fission, a variety of other elements are also created and become intimately associated with the uranium. Because they absorb neutrons, which energize the fission process, these accumulating fission products eventually poison the fuel by stopping the production of energy from it. The fission products may also damage the structural integrity of the fuel elements. Even though the uranium fuel is still present, sometimes in significant quantities, it is unburnable and will not power a reactor unless it is separated from the neutron-absorbing fission products by a method called fuel reprocessing. Construction of the Fuel Reprocessing Complex at the Chem Plant started in 1950 with the Bechtel Corporation serving as construction contractor and American Cyanamid Company as operating contractor. Although the Foster Wheeler Corporation assumed responsibility for the detailed working design of the overall plant, scientists at Oak Ridge designed all of the equipment that would be employed in the uranium separations process. After three years of construction activity and extensive testing, the plant was ready to handle its first load of irradiated fuel.

  2. HISTORICAL AMERICAN ENGINEERING RECORD - IDAHO NATIONAL ENGINEERING AND ENVIRONMENTAL LABORATORY, TEST AREA NORTH, HAER NO. ID-33-E

    2005-02-01

    Test Area North (TAN) was a site of the Aircraft Nuclear Propulsion (ANP) Project of the U.S. Air Force and the Atomic Energy Commission. Its Cold War mission was to develop a turbojet bomber propelled by nuclear power. The project was part of an arms race. Test activities took place in five areas at TAN. The Assembly & Maintenance area was a shop and hot cell complex. Nuclear tests ran at the Initial Engine Test area. Low-power test reactors operated at a third cluster. The fourth area was for Administration. A Flight Engine Test facility (hangar) was built to house the anticipated nuclear-powered aircraft. Experiments between 1955-1961 proved that a nuclear reactor could power a jet engine, but President John F. Kennedy canceled the project in March 1961. ANP facilities were adapted for new reactor projects, the most important of which were Loss of Fluid Tests (LOFT), part of an international safety program for commercial power reactors. Other projects included NASA's Systems for Nuclear Auxiliary Power and storage of Three Mile Island meltdown debris. National missions for TAN in reactor research and safety research have expired; demolition of historic TAN buildings is underway.

    2000-11-01

    The purpose of this study was to determine if there is adequate documentation of an historical role of African and African American involvement in science, engineering, and technology. Through the use of history of science and technology research methodology, along with an examination of the sociological and economic impacts of adequately accredited innovations and inventions contributed by Africans and African Americans, the researcher investigated their contributions to the following areas of science and technology: life science, physical sciences and chemistry, engineering, and science education. In regard to the timeframe for this study, the researcher specifically investigated African and African American involvement in science and technology that includes periods prior to black enslavement, scientific racism and colonialism, as well as during and after those periods. This research study reveals that there are adequate historical data regarding African and African American contributions to science, engineering, and technology. The data reveals that for many millennia African peoples have been continually involved in science and world science histories. The data further show that the numbers of African Americans acquiring BS, MS, Ph.D., Doctor of Science and Doctor of Engineering degrees in science and engineering disciplines are increasing. That these increases are not happening at a rate representative of the present or future African American percentages of the population. Consequently, because of future changes in our nation's demographics, increasing the numbers of people from under-represented groups who pursue scientific and engineering professions has become a matter of national security at the highest levels of government. Moreover, African Americans, Hispanics, and Native Americans are not pursuing careers or taking courses in science and engineering at a rate high enough to fulfill the prospective needs for the United States' industries, government

  10. Record mobility in transparent p-type tin monoxide films and devices by phase engineering

    KAUST Repository

    Caraveo-Frescas, Jesus Alfonso

    2013-06-25

    Here, we report the fabrication of nanoscale (15 nm) fully transparent p-type SnO thin film transistors (TFT) at temperatures as low as 180 C with record device performance. Specifically, by carefully controlling the process conditions, we have developed SnO thin films with a Hall mobility of 18.71 cm2 V-1 s-1 and fabricated TFT devices with a linear field-effect mobility of 6.75 cm2 V-1 s -1 and 5.87 cm2 V-1 s-1 on transparent rigid and translucent flexible substrates, respectively. These values of mobility are the highest reported to date for any p-type oxide processed at this low temperature. We further demonstrate that this high mobility is realized by careful phase engineering. Specifically, we show that phase-pure SnO is not necessarily the highest mobility phase; instead, well-controlled amounts of residual metallic tin are shown to substantially increase the hole mobility. A detailed phase stability map for physical vapor deposition of nanoscale SnO is constructed for the first time for this p-type oxide. © 2013 American Chemical Society.

    2009-05-01

    During the "The National Forum on the Future of the Defense Health Information System," a track focusing on "Systems Architecture and Software Engineering" included eight presenters. These presenters identified three key areas of interest in this field, which include the need for open enterprise architecture and a federated database design, net centrality based on service-oriented architecture, and the need for focus on software usability and reusability. The eight panelists provided recommendations related to the suitability of service-oriented architecture and the enabling technologies of grid computing and Web 2.0 for building health services research centers and federated data warehouses to facilitate large-scale collaborative health care and research. Finally, they discussed the need to leverage industry best practices for software engineering to facilitate rapid software development, testing, and deployment. PMID:19562959

  13. Experiences of African American Young Women in Science, Technology, Engineering, and Mathematics (STEM) Education

    Science.gov (United States)

    Kolo, Yovonda Ingram

    African American women are underrepresented in science, technology, engineering, and mathematics (STEM) fields throughout the United States. As the need for STEM professionals in the United States increases, it is important to ensure that African American women are among those professionals making valuable contributions to society. The purpose of this phenomenological study was to describe the experiences of African American young women in relation to STEM education. The research question for this study examined how experiences with STEM in K-10 education influenced African American young women's academic choices in their final years in high school. The theory of multicontextuality was used to provide the conceptual framework. The primary data source was interviews. The sample was composed of 11 African American young women in their junior or senior year in high school. Data were analyzed through the process of open coding, categorizing, and identifying emerging themes. Ten themes emerged from the answers to research questions. The themes were (a) high teacher expectations, (b) participation in extra-curricular activities, (c) engagement in group-work, (d) learning from lectures, (e) strong parental involvement, (f) helping others, (g) self-efficacy, (h) gender empowerment, (i) race empowerment, and (j) strategic recruitment practices. This study may lead to positive social change by adding to the understanding of the experiences of African American young women in STEM. By doing so, these findings might motivate other African American young women to pursue advanced STEM classes. These findings may also provide guidance to parents and educators to help increase the number of African American women in STEM.

    2014-07-01

    Native Americans are underrepresented in science, technology, engineering, and math (STEM) careers. We examine communal goal incongruence-the mismatch between students' emphasis on communal work goals and the noncommunal culture of STEM-as a possible factor in this underrepresentation. First, we surveyed 80 Native American STEM freshmen and found they more highly endorsed communal goals than individualistic work goals. Next, we surveyed 96 Native American and White American students in STEM and non-STEM majors and confirmed that both Native American men and women in STEM highly endorsed communal goals. In a third study, we conducted a follow-up survey and in-depth interviews with a subset of Native American STEM students in their second semester to assess their experiences of belonging uncertainty, intrinsic motivation, persistence intentions, and perceived performance in STEM as a function of their initial communal work goals. Results demonstrate the prominence of communal goals among incoming Native American freshman (especially compared with White male STEM majors) and the connection between communal goals and feelings of belonging uncertainty, low motivation, and perceived poor performance 1 semester later. The interview data illustrate that these issues are particularly salient for students raised within tribal communities, and that a communal goal orientation is not just a vague desire to "help others," but a commitment to helping their tribal communities. The interviews also highlight the importance of student support programs for fostering feelings of belonging. We end by discussing implications for interventions and institutional changes that may promote Native American student retention in STEM. PMID:25045952

  15. An examination of the identity development of African American undergraduate engineering students attending an HBCU

    Science.gov (United States)

    Taylor, Kenneth J.

    This study examined the identity development for a sample of 90 African American undergraduate engineering male and female students attending an HBCU. Using the Student Development Task and Lifestyle Assessment (SDTLA), which is based on Chickering and Reisser's identity development theory, differences in identity development were examined with respect to gender, academic classification, and grade point average. Previous research has shown the need to look beyond academic factors to understand and influence the persistence of African American engineering students. Non-cognitive factors, including identity development have proven to be influential in predicting persistence, especially for African American engineering students. Results from the analysis revealed significant means for academic classification and five of the dependent variables to include career planning peer relations, emotional autonomy, educational involvement, and establishing and clarifying purpose. Post hoc analysis confirmed significant differences for four of those dependent variables. However, the analysis failed to confirm statistical significant differences in peer relations due to academic classification. The significant decline in the mean scores for development in these four areas, as students progressed from sophomore to senior year revealed strong implications for the need to provide programming and guidance for those students. Institutions of higher education should provide more attention to the non-cognitive areas of development as a means of understanding identity development and working toward creating support systems for students.

  16. Centennial-scale solar forcing of the South American Monsoon System recorded in stalagmites

    Novello, Valdir F.; Vuille, Mathias; Cruz, Francisco W.; Stríkis, Nicolás M.; de Paula, Marcos Saito; Edwards, R. Lawrence; Cheng, Hai; Karmann, Ivo; Jaqueto, Plínio F.; Trindade, Ricardo I. F.; Hartmann, Gelvam A.; Moquet, Jean S.

    2016-04-01

    The South American Monsoon System (SAMS) is generally considered to be highly sensitive to Northern Hemisphere (NH) temperature variations on multi-centennial timescales. The direct influence of solar forcing on moisture convergence in global monsoon systems on the other hand, while well explored in modeling studies, has hitherto not been documented in proxy data from the SAMS region. Hence little is known about the sensitivity of the SAMS to solar forcing over the past millennium and how it might compete or constructively interfere with NH temperature variations that occurred primarily in response to volcanic forcing. Here we present a new annually-resolved oxygen isotope record from a 1500-year long stalagmite recording past changes in precipitation in the hitherto unsampled core region of the SAMS. This record details how solar variability consistently modulated the strength of the SAMS on centennial time scales during the past 1500 years. Solar forcing, besides the previously recognized influence from NH temperature changes and associated Intertropical Convergence Zone (ITCZ) shifts, appears as a major driver affecting SAMS intensity at centennial time scales.

  17. Constraining peatland environmental change: exploiting the emerging eastern North American crypto-tephrostratigraphic record

    Science.gov (United States)

    Mackay, H.; Hughes, P. D.; Langdon, P.

    2013-12-01

    The relatively recent advances in tephrochronology have led to the investigation of non-visible (crypto) tephra horizons in sediment distal from volcanic origins. Such studies have been predominantly centered on western Europe; however the potential of North American cryptotephras is rapidly emerging. This not only facilitates the construction of more robust chronologies in areas thought to be outside the scope of this technique, but also the provision of isochrons enhances comparisons of environmental spatial synchronicity across sites and regions. Four tephrostratigraphies across a transect of peatlands in Maine, Nova Scotia and south-western Newfoundland have been constructed. A total of 18 horizons were detected over the last ca. 4000 years, the preliminary geochemical analysis of which suggest that all constrained eruptions originate from the Cascade Range and Alaska ca. 5000-6000 km to the west of the sites. These results complement the one existing record from eastern Newfoundland (Pyne-O'Donnell et al. 2012), facilitating the extension of the late Holocene crypto-tephrostratigraphic framework for the eastern seaboard of North America. Peatlands are considered to be ideal archives for preserving tephrostratigraphies since cryptotephra horizons are often present in discrete layers, thought to represent primary airfall. Such preservation in this setting is critiqued here, assisted by radiocarbon measurements. The tephra horizons are used as pinning-points between records to address the wider aim of the study: to examine the terrestrial manifestations of late Holocene climatic change across an eastern North American climatic gradient. Of particular interest are the temporal and spatial characteristics of changes in peatland accumulation and reconstructed water table depth during the most dominant late Holocene climatic perturbations: the Medieval Climatic Anomaly and the Little Ice Age. This time period is constrained by the most dominant eruption, White River

  18. American Indians, hunting and fishing rates, risk, and the Idaho National Engineering and Environmental Laboratory

    International Nuclear Information System (INIS)

    Hunting, fishing, and recreational rates of 276 American Indians attending a festival at Fort Hall, near the Idaho National Engineering and Environmental Laboratory (INEEL), were examined. Nearly half of the sample lived on the Fort Hall Reservation, and half were American Indians from elsewhere in the western United States. An additional 44 White people attending the festival were also interviewed. The hypothesis that there are differences in hunting, fishing, and recreational rates as a function of tribal affiliation, educational level, gender, and age was examined. Information on hunting and fishing rates are central for understanding potential exposure scenarios for American Indians if the Department of Energy's INEEL lands are ever opened to public access, and the data are important because of the existence of tribal treaties that govern the legal and cultural rights of the Shoshone-Bannock regarding INEEL lands. Variations in hunting, fishing, and photography rates were explained by tribal affiliation (except fishing), gender, age, and schooling. Hunting rates were significantly higher for Indians (both those living on Fort Hall and others) than Whites. Men engaged in significantly higher rates of outdoor activities than women (except for photography). Potential and current hunting and fishing on and adjacent to INEEL was more similar among the local Whites and Fort Hall Indians than between these two groups and other American Indians

    Hunting, fishing, and recreational rates of 276 American Indians attending a festival at Fort Hall, near the Idaho National Engineering and Environmental Laboratory (INEEL), were examined. Nearly half of the sample lived on the Fort Hall Reservation, and half were American Indians from elsewhere in the western United States. An additional 44 White people attending the festival were also interviewed. The hypothesis that there are differences in hunting, fishing, and recreational rates as a function of tribal affiliation, educational level, gender, and age was examined. Information on hunting and fishing rates are central for understanding potential exposure scenarios for American Indians if the Department of Energy's INEEL lands are ever opened to pubic access, and the data are important because of the existence of tribal treaties that govern the legal and cultural rights of the Shoshone-Bannock regarding INEEL lands. Variations in hunting, fishing, and photography rates were explained by tribal affiliation (except fishing), gender, age, and schooling. Hunting rates were significantly higher for Indians (both those living on Fort Hall and others) than Whites. Men engaged in significantly higher rates of outdoor activities than women (except for photography). Potential and current hunting and fishing on and adjacent to INEEL was more similar among the local Whites and Fort Hall Indians than between these two groups and other American Indians.

    The American Indian Science and Engineering Society (AISES) has been funded under a U.S. Department of Energy (DOE) grant (Grant Award No. DE-SC0004058) to host an Intertribal Middle-School Science and Math Bowl (IMSSMB) comprised of teams made up of a majority of American Indian students from Bureau of Indian Education-funded schools and public schools. The intent of the AISES middle school science and math bowl is to increase participation of American Indian students at the DOE-sponsored National Science Bowl. Although national in its recruitment scope, the AISES Intertribal Science and Math Bowl is considered a “regional” science bowl, equivalent to the other 50 regional science bowls which are geographically limited to states. Most regional bowls do not have American Indian student teams competing, hence the AISES bowl is meant to encourage American Indian student teams to increase their science knowledge in order to participate at the national level. The AISES competition brings together teams from various American Indian communities across the nation. Each team is provided with funds for travel to and from the event, as well as for lodging and meals. In 2011 and 2012, there were 10 teams participating; in 2013, the number of teams participating doubled to 20. Each Science and Math Bowl team is comprised of four middle school — grades 6 through 8 — students, one alternate, and a teacher who serves as advisor and coach — although in at least two cases, the coach was not a teacher, but was the Indian Education Coordinator. Each team member must have at least a 3.0 GPA. Furthermore, the majority of students in each team must be comprised of American Indian, Alaska Native or Native Hawaiian students. Under the current DOE grant, AISES sponsored three annual middle school science bowl competitions over the years 2011, 2012 and 2013. The science and math bowls have been held in late March concurrently with the National American Indian Science and

    We are living in a definite time of change. Distinct changes are being experienced in our most sacred and natural environments. This is especially true on Native lands. Native people have lived for millennia in distinct and unique ways. The knowledge of balancing the needs of people with the needs of our natural environments is paramount in all tribal societies. This inherent knowledge has become the foundation on which to build a "blended" contemporary understanding of western science. The Dakota's and Northern California have recognized the critical need in understanding successful tribal strategies to engage educational systems (K-12 and higher education), to bring to prominence the professional development opportunities forged through working with tribal peoples and ensure the growth of Native people in STEM (Science, Technology, Engineering and Mathematics) professions. The presentation will highlight: 1) current philosophies on building a STEM Native workforce; 2) successful educational programs/activities in PreK-Ph.D. systems; 3) current Native professionals, their research and tribal applicability; and 4) forwarding thinking for creating sustainable environmental and social infrastructures for all people. South Dakota School of Mines and Technology (SDSM&T) and Humboldt State University (HSU) have been recognized nationally for their partnerships with Native communities. SDSM&T has set record numbers for graduating Native students in science and engineering. SDSM&T had 27 graduates in five years (2000-2005) and hosted more than 1000+ Native students for programs and activities. Humboldt State University is the only university in the CSU system with a program focusing specifically on Natives in natural resources, science and engineering as well as a Native American Studies degree. Both universities have designed programs to meet current needs and address challenging issues in Earth, Wind, Fire and Water. The programs are funded through NASA, NSF, NIH and

  7. Global change and thermal history as recorded by northern North American tree-ring data

    International Nuclear Information System (INIS)

    Thermal regimes and heat exchange of the polar and subpolar regions play a key role in global climatic change. Principal components analysis of instrumental data for the globe indicate that northern high latitude temperatures are a very strong component of global temperature variations. Tree-ring data from thermally responsive sites in Canada and Alaska yield records of polar and subpolar temperature changes for centuries prior to the relatively short period of instrumental measurements. Tree-ring width based reconstructions of Arctic and northern North American temperatures through 1973 reflect the general positive trend in large-scale instrumental data over the past century. These reconstructions, as well as the raw tree-ring measurements, show that this recent period of warming is unusual relative to the prior few centuries. More recently developed data from Canada confirm previous reconstructions. A maximum latewood density chronology from the Northwest Territories shows a stronger climatic response to warm-season temperatures than ring width data from the same trees. The density information also shows a response to several other temperature-related parameters, including ground-level solar radiation measurements. In detecting and quantifying global climatic change, tree-ring analysis of high latitude trees provides evidence of recent wide-scale warming in northern North America. This warming will affect boreal forests, northern waters, and human activities. However, more, studies are needed to better determine the extent of recent and possible future climatic change and the resulting environmental consequences

  14. Factors affecting the matriculation of African American undergraduate students in science, mathematics, engineering, and technology

    Science.gov (United States)

    Hall, Alfred L., II

    Previous research studies indicated that African Americans remain severely underrepresented in the field of science, mathematics, engineering, and technology (SMET), making up only 3% of that workforce, while representing 11.1% of all professional and related workers and 12.6% of the general population. As this country moves towards a more culturally diverse population, then representation of African Americans in SMET-related fields must be addressed in order to ensure our nation's competitiveness in a global market. This research study analyzed characteristics of African American undergraduate SMET majors participating in the Alliance for Minority Participation (AMP) program in six different states located in the Southeast region of the United States. These states consisted of Alabama, Florida, Georgia, Mississippi, North Carolina, and South Carolina. AMP program participants completed a survey questionnaire, which collected information about potential factors that could affect their matriculation in SMET programs of studies at their respective institutions. Follow-up interviews and focus group sessions were also conducted with AMP participants to provide supplemental information to the survey data. The results of student responses were analyzed according to the type of institution the students attended (Historically Black College or University and Majority White Institution) as well as by the statewide Alliance program in which the students were involved. The students responded to survey questions that asked for their reasons for majoring in their field of study, their level of satisfaction with their institution, their impressions of student support programs and persons, their impressions of faculty and advisors, their reasons for thinking of switching majors, and their level of high school preparation. Statistical analyses of the student responses found that African American AMP students attending Historically Black Colleges and Universities differed from those

    A Holocene stalagmite from Botuverá Cave, southeastern Brazil was analyzed by LA-ICPMS for Mg/Ca, Sr/Ca, Ba/Ca. The observed variability in the record was demonstrated to be modulated by prior calcite precipitation, and, thus, is interpreted to reflect monsoon intensity. We find that the calcite δ18O is strongly correlated with Sr/Ca, indicating that atmospheric circulation over South America and monsoon intensity have been tightly correlated throughout most of the Holocene, both directly responding to solar precession. Comparison with other contemporaneous high-resolution hydroclimate records reveals that SAMS has shown a degree of complexity during the Holocene not previously detected, with periods where the South American Convergence Zone (SACZ) expanded to cover most of the South American sub-continent, and coincident with periods of low-SST in the north Atlantic. We also detect periods where rainfall amount in northeastern and southeastern Brazil are markedly anti-phased, suggesting a north-south migration of SACZ, which it appears to be mediated by solar irradiance. The high-resolution nature of our record allow us to examine the effect that Holocene climate anomalies had upon SAMS dynamics and hydroclimate in southeastern Brazil, in particular the 8.2 ka event and the Little Ice Age. In addition to confirm the internal structure of the events, we also detect the possible consequences of the climatic anomalies upon ocean-atmosphere interactions through its effects upon SAMS.

    1997-01-01

    In mid-1996, the FDA called for discussions on regulation of clinical software programs as medical devices. In response, a consortium of organizations dedicated to improving health care through information technology has developed recommendations for the responsible regulation and monitoring of clinical software systems by users, vendors, and regulatory agencies. Organizations assisting in development of recommendations, or endorsing the consortium position include the American Medical Informatics Association, the Computer-based Patient Record Institute, the Medical Library Association, the Association of Academic Health Sciences Libraries, the American Health Information Management Association, the American Nurses Association, the Center for Healthcare Information Management, and the American College of Physicians. The consortium proposes four categories of clinical system risks and four classes of measured monitoring and regulatory actions that can be applied strategically based on the level of risk in a given setting. The consortium recommends local oversight of clinical software systems, and adoption by healthcare information system developers of a code of good business practices. Budgetary and other constraints limit the type and number of systems that the FDA can regulate effectively. FDA regulation should exempt most clinical software systems and focus on those systems posing highest clinical risk, with limited opportunities for competent human intervention. PMID:9391932

    Full Text Available The newly updated inventory of the Latin American Pollen Database (LAPD offers an important overview of data available for multi-proxy and multi-site purposes. However, heterogeneous paleoecological databases are not suitable to be integrated without an uncertainty assessment of existing chronologies. Therefore, we collected all chronological control points and age model metadata from the LAPD literature to create a complementary chronological database of 5116 dates from 1097 pollen records. We start with an overview on chronological dating and reporting in Central and South America. Specific problems and recommendations for chronology reporting are discussed. Subsequently, we implement a temporal quality assessment of pollen records from northwest South-America to support research on climate forcers and responses at a centennial-millennial time-scale. New chronologies are generated for 233 pollen records based on updated calibration curves. Different time windows are discussed on sample resolution and temporal uncertainty. Approximately one in four pollen diagrams depicts < 500 years resolution data at the Younger Dryas/Holocene transition. Overall, our analyses suggest that the temporal resolution of multi-site syntheses of late Pleistocene fossil pollen records in the northwest South-America is ca. 240 years, a resolution which allows analysis of ecological responses to centennial-millennial-scale climate change during the last deglaciation.

    The BREN (Bare Reactor Experiment, Nevada) Tower Complex is significant for its role in the history of nuclear testing, radiation dosimetry studies, and early field testing of the Strategic Missile Defense System designs. At the time it was built in 1962, the 1,527 ft (465 m) BREN Tower was the tallest structure west of the Mississippi River and exceeded the height of the Empire State Building by 55 ft (17 m). It remains the tallest ever erected specifically for scientific purposes and was designed and built to facilitate the experimental dosimetry studies necessary for the development of accurate radiation dose rates for the survivors of Hiroshima and Nagasaki. The tower was a key component of the Atomic Bomb Casualty Commission’s (ABCC) mission to predict the health effects of radiation exposure. Moved to its current location in 1966, the crucial dosimetry studies continued with Operation HENRE (High Energy Neutron Reactions Experiment). These experiments and the data they generated became the basis for a dosimetry system called the Tentative 1965 Dose or more commonly the T65D model. Used to estimate radiation doses received by individuals, the T65D model was applied until the mid-1980s when it was replaced by a new dosimetry system known as DS86 based on the Monte Carlo method of dose rate calculation. However, the BREN Tower data are still used for verification of the validity of the DS86 model. In addition to its importance in radiation heath effects research, the BREN Tower Complex is also significant for its role in the Brilliant Pebbles research project, a major component of the Strategic Defense Initiative popularly known as the “Star Wars” Initiative. Instigated under the Reagan Administration, the program’s purpose was to develop a system to shield the United States and allies from a ballistic missile attack. The centerpiece of the Strategic Defense System was space-based, kinetic-kill vehicles. In 1991, BREN Tower was used for the tether tests of the Brilliant Pebbles prototype vehicle at the earth’s surface prior to the more costly space testing program. The success of these tests established the Brilliant Pebbles program as an essential component of America’s space-based missile defense system even after the dismantling of the Soviet Union. Data from the Brilliant Pebbles research program continues to inspire current missile defense system research (Independent Working Group 2009).

    Charge carrier mobility is still the most challenging issue that should be overcome to realize everyday organic electronics in the near future. In this Communication, we show that introducing smart side-chain engineering to polymer semiconductors can facilitate intermolecular electronic communication. Two new polymers, P-29-DPPDBTE and P-29-DPPDTSE, which consist of a highly conductive diketopyrrolopyrrole backbone and an extended branching-position-adjusted side chain, showed unprecedented record high hole mobility of 12 cm(2)/(V·s). From photophysical and structural studies, we found that moving the branching position of the side chain away from the backbone of these polymers resulted in increased intermolecular interactions with extremely short π-π stacking distances, without compromising solubility of the polymers. As a result, high hole mobility could be achieved even in devices fabricated using the polymers at room temperature. PMID:24053786

    Practicing physicians have limited time for consulting medical knowledge and records. We have previously shown that using icons instead of text to present drug monographs may allow contraindications and adverse effects to be identified more rapidly and more accurately. These findings were based on the use of an iconic language designed for drug knowledge, providing icons for many medical concepts, including diseases, antecedents, drug classes and tests. In this paper, we describe a new project aimed at extending this iconic language, and exploring the possible applications of these icons in medicine. Based on evaluators' comments, focus groups of physicians and opinions of academic, industrial and associative partners, we propose iconic applications related to patient records, for example summarizing patient conditions, searching for specific clinical documents and helping to code structured data. Other applications involve the presentation of clinical practice guidelines and improving the interface of medical search engines. These new applications could use the same iconic language that was designed for drug knowledge, with a few additional items that respect the logic of the language. PMID:20841669

  4. "Sounds like something a white man should be doing": Academic identity in African American female engineering students

    Science.gov (United States)

    Stitt, Rashunda LaRuth

    This study exposed the way African American female engineering students constructed their academic identities by focusing on their lived experiences. Participants included nine engineering students at Mid-South University (pseudonym) who identified as African American females. Participants were required to sit for one semi-structured academic life history interview that focused on their academic experiences from early childhood to present. This study employed two levels of theory in order to obtain a comprehensive view of participants' experiences. Black feminist theory, which accounts for the intersectionality of participants' race and gender, served as the macro level theory and academic identity, which accounts for the individual's sense of identity within an academic context, served as the mid-level theory. I engaged in thematic analysis, narrative analysis, and creative analytic practice in order to highlight similarities between participants' stories, differences between participants' experiences, and to make this research accessible to individuals outside of academia. As a result, the following three themes emerged to highlight the similarities between participants: (a) just because you struggle, does not mean you should quit; (b) engineering is something you cannot do alone; and (c) I can be creative and do math and science? That's cool! Narrative analysis exposed the academic identity statuses of participants to be either identity achieved, identity moratorium, identity foreclosed or identity diffused. The final piece of analysis involved creating a play that highlights the experiences of an African American girl's pursuit of her engineering degree. Additionally, the final chapter provides conclusions, implications, suggestions for future research, and limitations of the current study.

    Jane M. Brokel

    2011-01-01

    Full Text Available An existing electronic health record (EHR system was re-engineered with cross-functional workflows to enhance the efficiency and clinical utility of health information technology. The new designs were guided by a systematic review of clinicians' requests, which were garnered by direct interviews. To design cross-functional, patient-centered workflows, several multi-disciplinary teams from the health system of hospitals, clinics, and other services participated. We identified gaps and inconsistencies with current care processes and implemented changes that improved workflow for patients and clinicians. Our findings emphasize that, to coordinate care between many providers, process workflow must be standardized within and across settings and focus on patient care processes, not the technology. These new, comprehensive, admission-to-discharge workflows replaced the older, functional- and departmental-process flow charts that had fallen short. Our experience led to integrated redesign of the workflows, review prior to implementation and ongoing maintenance of this process knowledge across 37 hospital facilities.

    African American women maintain distinctive social locations at the intersection of race, gender, and class (Crenshaw, 1991; Collins, 1986; 2000; Wing, 2003). However, their voices, interpretation of experiences, and concern with the use of formal education as a mechanism for racial uplift have not been priorities in feminist movements (hooks, 1981; 1989; Perkins, 1993; Smith, 1998; Spitzack & Carter, 1987). Alternatively, Black feminist thought (Collins, 1990; 2000) is a theory constructed by and for African American women. Given the consequences of pursuing formal education in the histories of African American women and the paucity of African American women represented in STEM fields, the purpose of this study was to (a) reveal how African American women conducting research in STEM disciplines accomplished their professional goals, (b) learn how the women negotiated their multiple identities (i.e. race, gender, and class), (c) link the history of educational experiences among African Americans with agendas for social justice, (d) understand how African American women in STEM align their personal accomplishments with broader agendas for activism in higher education, and (e) discover whether there is a collective identity that successful African American women in STEM share. Using Black feminist thought (Collins, 1986; 2000) and narrative analysis of semi- interviews with eight African American women in STEM, the findings from this study revealed: (a) the women in this study described the challenges of pursuing a career in STEM from a feminist perspective, identifying gender as more significant than race; (b) the women in this study experienced more positive interactions with Black male, White female, and White male mentors than with Black female mentors; (c) the women in this study described the use of empowering strategies for overcoming obstacles in their academic pathways; and (d) their collective academic identities were formed by early interactions with

    Full Text Available We review the history of the South American summer monsoon (SASM over the past ~2000 yr based on high-resolution stable isotope proxies from speleothems, ice cores and lake sediments. Our review is complemented by an analysis of an isotope-enabled atmospheric general circulation model (GCM for the past 130 yr. Proxy records from the monsoon belt in the tropical Andes and SE Brazil show a very coherent behavior over the past 2 millennia with significant decadal to multidecadal variability superimposed on large excursions during three key periods: the Medieval Climate Anomaly (MCA, the Little Ice Age (LIA and the current warm period (CWP. We interpret these three periods as times when the SASM's mean state was significantly weakened (MCA and CWP and strengthened (LIA, respectively. During the LIA each of the proxy archives considered contains the most negative δ18O values recorded during the entire record length. On the other hand, the monsoon strength is currently rather weak in a 2000-yr historical perspective, rivaled only by the low intensity during the MCA. Our climatic interpretation of these archives is consistent with our isotope-based GCM analysis, which suggests that these sites are sensitive recorders of large-scale monsoon variations.

    We hypothesize that these centennial-scale climate anomalies were at least partially driven by temperature changes in the Northern Hemisphere and in particular over the North Atlantic, leading to a latitudinal displacement of the ITCZ and a change in monsoon intensity (amount of rainfall upstream over the Amazon Basin. This interpretation is supported by several independent records from different proxy archives and modeling studies. Although ENSO is the main forcing for δ18O variability over tropical South America on interannual time scales, our results suggest that its influence may be significantly modulated by North Atlantic climate variability on longer time scales

  10. Late Quaternary change in the North American (Mexican) Monsoon: variability in terrestrial and marine records and possible mechanisms

    The Late Quaternary history of the North American (or Mexican) monsoon (NAM) remains poorly understood, with continuing debates about the relative importance of insolation forcing, the role of the Laurentide Ice Sheet (LIS), the expression of warm (D-O) and cold (H) events in the North Atlantic and the influence of the Pacific. To date, more information has been available from the southern and northern margins of the NAM region than from its tropical and subtropical core. This is significant because to the south of the NAM region, the direct effect of ITCZ location is likely to be stronger and any potential influence of the LIS weaker, and to the north, there is an important change in present day precipitation seasonality (from summer to winter), an opposite response to forcings such as ENSO/PDO and AMO and probably a stronger influence of the LIS. As a result, the interpretation of speleothem records from New Mexico (e.g. Asmerom et al., 2010) and Arizona (e.g. Wagner et al., 2010), in the southwestern USA and marine records such as Cariaco (Peterson and Haug, 2006) and lake records such as Peten Iztá (Hodell et al., 2008) may not be applicable to the tropical NAM core. Here we present results from two lacustrine sequences in Mexico (Sayula 20oN; Babicora 29oN) and a marine core record from the central part of the Gulf of California (27oN) all extending back at least through MIS3 (ca. 60 kyr BP). Although lacking the chronological precision of the speleothem sequences, these multiproxy records preserve evidence of centennial and millennial scale variability. MIS3 is marked by generally wetter conditions in the lake basins and warmer SSTs in the marine record, particularly during D/O events, which can be attributed to a stronger monsoon as well northward displacement of the ITCZ. This contrasts with the standard interpretation of the speleothem sequences where D/O events are dry. In contrast, H events are usually drier/cooler (weaker NAM, reduced summer

    Full Text Available The article explores the ambitions, challenges, successes and perceived failures and disappointments of the policies pursued by the Democratic administrations of President Barack Obama, with particular focus on Honduras, Mexico and Colombia. The article notes the eloquent and optimistic rhetoric of Obama, in his first presidential campaign and in the early days of his first administration, commitments to significant change in U.S. policy toward Latin America. In contrast the record of the first five years of his administrations have witnessed the continuation of policies which are difficult to distinguish from those of his predecessor. The article also notes the general decline in U.S. influence in the region. There has been insignificant change in Cuban policy, save for a liberalization of family travel to Cuba. His administration implemented the controversial Free Trade Agreement with Colombia which his own party leaders had long opposed. He has maintained the funding levels of the equally controversial Plan Colombia which began under Bill Clinton, and he has continued to adhere to a largely Republican agenda on border security with Mexico.

    International Nuclear Information System (INIS)

    The paper describes a new website called SISMA, i.e. Site of Italian Strong Motion Accelerograms, which is an Internet portal intended to provide natural records for use in engineering applications for dynamic analyses of structural and geotechnical systems. SISMA contains 247 three-component corrected motions recorded at 101 stations from 89 earthquakes that occurred in Italy in the period 1972-2002. The database of strong motion accelerograms was developed in the framework of a joint project between Sapienza University of Rome and University of California at Los Angeles (USA) and is described elsewhere. Acceleration histories and pseudo-acceleration response spectra (5% damping) are available for download from the website. Recordings can be located using simple search parameters related to seismic source and the recording station (e.g., magnitude, Vs30, etc) as well as ground motion characteristics (e.g. peak ground acceleration, peak ground velocity, peak ground displacement, Arias intensity, etc.)

    Decadal and centennial mean state changes in South American summer monsoon (SASM) precipitation during the last 2,300 years are detailed using an annually resolved authigenic calcite record of precipitation δ(18)O from a varved lake in the Central Peruvian Andes. This unique sediment record shows that δ(18)O peaked during the Medieval Climate Anomaly (MCA) from A.D. 900 to 1100, providing evidence that the SASM weakened considerably during this period. Minimum δ(18)O values occurred during the Little Ice Age (LIA) between A.D. 1400 and 1820, reflecting a prolonged intensification of the SASM that was regionally synchronous. After the LIA, δ(18)O increased rapidly, particularly during the current warm period (CWP; A.D. 1900 to present), indicating a return to reduced SASM precipitation that was more abrupt and sustained than the onset of the MCA. Diminished SASM precipitation during the MCA and CWP tracks reconstructed Northern Hemisphere and North Atlantic warming and a northward displacement of the Intertropical Convergence Zone (ITCZ) over the Atlantic, and likely the Pacific. Intensified SASM precipitation during the LIA follows reconstructed Northern Hemisphere and North Atlantic cooling, El Niño-like warming in the Pacific, and a southward displacement of the ITCZ over both oceans. These results suggest that SASM mean state changes are sensitive to ITCZ variability as mediated by Western Hemisphere tropical sea surface temperatures, particularly in the Atlantic. Continued Northern Hemisphere and North Atlantic warming may therefore help perpetuate the recent reductions in SASM precipitation that characterize the last 100 years, which would negatively impact Andean water resources.

  18. The experiences of African-American students majoring in engineering: Cognitive, non-cognitive and situational aspects

    To understand the causes for the disproportionately high rate of attrition among ethnic minority students, it is important to consider not only how they differ from the majority population, but what differences exist in personal qualities and academic preparation within groups at particular types of institutions, and within particular majors. The purpose of this study is to examine the experiences of African-American students enrolled in engineering at a predominately white, selective research university to determine which cognitive, non-cognitive and situational variables impact their progress towards graduation. The goal was to see how African-American students who meet or exceed the minimum criteria for admission perceive their experience on campus, and what strategies they use to manage their day-to-day existence. The study was conducted using personal interviews guided by an open-ended questionnaire. The qualitative methodology allowed students to assess the college experience through their own cultural lens, and to identify the cognitive, non-cognitive, and situational variables important to them. Responses were sorted by class and gender, tabulated and grouped into categories. Interpretation was primarily descriptive. Consistencies, inconsistencies, patterns and relationships to concepts in the literature and to the research questions were discussed. Findings indicate that well prepared students become less confident about their commitment to engineering and their ability to succeed academically after they begin matriculating rather than before, and that redefinition of what it means to be academically successful is an effective coping mechanism to sustain the effort required to master courses. The study suggests that the current focus on the impact of the freshman year transition on student retention should be expanded to include the sophomore year. This is particularly true for institutions where engineering students spend the first year in a core

  19. Evolution of the North American Monsoon from the middle Holocene to the present recorded in marine sediments from low Gulf of California

    New results of a reconstruction of the summer precipitation in the North American Monsoon area, which is the largest atmospheric circulation feature over much of northwest Mexico, and the southwest the USA. This regime results from the interplay between sea surface temperatures (SSTs) in the northeast tropical Pacific, solar variability, continental topography, land snow cover and soil moisture over the western North America as well as patterns of atmospheric pressure. The links between these factors and the monsoonal variability appear to be of variable importance during the short instrumental record. This hampers any prediction on the future evolution of the climatic regime in a warming climate. We produce an X-Ray Fluorescence record of the relative abundances of Si and Al in high resolution laminated sediments obtained from the Pescadero basin (24N, 108W) as semi-quantitative index of terrigenous input. This record links the transport of terrigenous materials by summer precipitation in the North American Monsoon region, in mountain range Sierra Madre NW Mexico. The record was constructed from XRF scan measurements of a composite core (260cm long) based on several box and Kasten cores, the age model is based on 8 14C AMS ages, producing a record with a mean temporal resolution of 0.5 yr. The variability of the NAM shows a decreasing trend between the middle Holocene to the present. This general trend is parallel to many other records like speleothems, ice cores, pollen fossil, and elemental content in marine and lake sediments. Spectral and cross-spectral analysis were made in order to search for some similarities with other climatic features on global scale, and thus evaluate possible links between the low and high latitudes climate variability. In addition, we compare the last century precipitation with the past few thousand years and explore some possible effect of climate change in the North American Monsoon behaviour.

  3. Understanding him in STEM: Sharing the stories of African American male scholars in engineering academic programs at a predominantly White university

    Science.gov (United States)

    Hayes, Robert E., III

    Globalization of the world economy has confirmed the need for citizens to exemplify competitive capacities in science, technology, engineering, and mathematics fields. Since the 1970s, American higher education has seen increasing numbers of students entering college but has witnessed a decline in the number of students enrolling in STEM programs. African American men fall behind other students in regards to academic performance, persistence, and success throughout primary, secondary, and tertiary schooling. Accordingly, participation of African American men in STEM disciplines is low in comparison to White males and other race groups. Various factors have been identified as contributing to the academic failures of Black men. Poor academic and social preparedness, racial identity issues, institutional climates, negative stereotypes, and fear of success have been cited as potential contributors to the relative invisibility of African American men in STEM disciplines. This study explores the life stories of five African American male scholars in the college of engineering at a predominantly white university. The goal of the qualitative investigation is to help university faculty and administrators understand the institutional, interpersonal, and collective mechanisms influencing the success identities of African American male undergraduates in STEM academic programs. Understanding the lived experiences of this population may help universities innovate stronger supports for men of color in college and broaden the borders for all students interested in STEM careers.

    The purpose of this research was to distinguish the similarities and differences in coping strategies of African American engineering students by analyzing their perceptions of stereotype threat at three academic institution types, Predominantly White Institutions (PWI), ethnically diverse, and Historically Black Colleges and Universities (HBCUs). The researcher collected demographic and survey data using the Stereotype Vulnerability Scale (SVS). The study was offered to the entire population of African American engineering students at each college using an online survey. Results were analyzed using MANOVA and Pearson's correlational statistical analyses to test the hypotheses. Findings revealed that little differences exist between students' scores on an assessment of stereotype vulnerability, with a few areas showing that HBCUs and ethnically diverse universities are doing a similar job in addressing perceptions of their African American engineering students. Finding also revealed that the percentage of African American students at a university did not correlate with the scores on the SVS accept on questions related to the personal feelings students have about their race. The strongest findings related to the differences in male and female students across the universities. African American female engineering students appeared to perceive more stereotype threat than did their male counterparts; although, this fining was not statistically significant. Overall, no statistically significant differences were found between students' perceptions of stereotype threat at the three types of universities. Future research should expand the number of survey participants at the current universities, add more HBCUs to the study population, run similar experiments in different parts of the country, compare stereotype threat in private and elite universities, use ethnically diverse universities as models for minority student development, and use new or improved survey instruments

  7. Strong ground motion data from the 1983 Borah Peak, Idaho earthquake recorded at the Idaho National Engineering Laboratory

    International Nuclear Information System (INIS)

    The 1983 Borah Peak, Idaho Earthquake was the largest normal faulting event to occur in the last 20 years. There were no near-field recordings of ground motion during the main shock, however, thirteen accelerographs in a permanent array at the Idaho National Engineering Laboratory (INEL) recorded the event at epicentral distances of 90-110 km. Peak horizontal accelerations (PGA) recorded at accelerographs above ground-floor level range from 0.037 to 0.187 g. Accelerographs at basement and free-field sites recorded as low as 0.022 g and as high as 0.078 g. Peak vertical accelerations range from 0.016 g ground level to 0.059 g above ground floor level. A temporary array of digital seismographs deployed by the US Geological Survey (USGS) in the epicentral area recorded ground motion from six large aftershocks at epicentral distances of 4-45 km; the largest of these aftershocks also triggered four accelerographs in the INEL array. Two separate analyses were used to estimate near-field ground motion. The first analysis uses the attenuation of the aftershock PGA measurements to extrapolate the INEL main shock PGA measurements into the near-field. This estimates an upper limit of 0.8 g for near-field ground motion. In the second analysis, a set of main shock accelerograms were synthesized. Wave propagation effects were determined from aftershock recordings at one of the USGS portable stations and an INEL seismograph station. These effects were removed from one of the INEL main shock acceleration traces. The synthetic accelerograms were derived for a hypothetical station southwest of Mackay, Idaho. The PGA measured from the synthetic accelerograms were 0.08, 0.14, 0.15, 0.23 g. These estimates correlate well with ground motion expected for an area of Intensity VII. 12 references, 8 figures, 1 table

  8. Draft fracture mechanics code case for American Society of Mechanical Engineers NUPACK rules

    International Nuclear Information System (INIS)

    The containment boundaries of most spent-fuel casks certified for use in the United States by the Nuclear Regulatory Commission are constructed with stainless steel, a material that is ductile in an engineering sense at all temperatures and for which, therefore, fracture mechanics principles are not relevant for the containment application. Ferritic materials may fail in a nonductile manner at sufficiently low temperatures, so fracture mechanics principles may be applied to preclude nonductile fracture. Because of the need to transport and store spent nuclear fuel safely in all types of climatic conditions, these vessels have regulatory lowest service temperatures that range down to -40 C (-40 F) for transport application. Such low service temperatures represent a severe challenge in terms of fracture toughness to many ferritic materials. Linear-elastic and elastic-plastic fracture mechanics principles provide a methodology for evaluating ferritic materials under such conditions

    2011-12-01

    This phenomenological study examined the experiences of twelve female African Americans enrolled as fulltime undergraduate engineering students at North Carolina Agricultural and Technical State University, an historically Black university, and seven female African Americans enrolled as undergraduate engineering students at Purdue University in West Lafayette, Indiana, a traditionally White institution. Interviews provided insights into the "lived" experiences of these young women and the factors they believe have contributed to their success in their respective engineering programs. Data analysis involved coding each participant's responses to interview questions using Atlas.ti, a powerful qualitative data analysis tool. This generated 181 codes that were further categorized into nine emergent themes, indicating the potential for extensive associations among the variables. The emergent themes are as follows: (1) Demographic information/special circumstances, (2) Personal attributes and characteristics, (3) Personal insights, (4) Sense of mission, (5) Sources of negative stress, (6) Success strategies, (7) Various forms of support, (8) Would/would not have made it to where she is now, and (9) Being African American and female in engineering. Analysis of these themes and their relationships led to the development of the Frillman Model of Emergent Themes in Female African American Engineering Students. Success. In addressing similarities and differences, three overriding theme categories emerged. These were: (1) Four personhood themes and dual social identity theme; (2) Environmental input and response theme; and (3) Outcome emergent theme of Would/Would not have made it to where she is now. Recommendations were made for future research to expand upon this exploratory study.

    2015-12-01

    The Western North American climate is influenced by the sea surface temperatures in the NE tropical Pacific, the summer expansion of the subtropical high, the mid-latitude Westerlies and land snow covering. The interplay of these features of the climate exert further control to the largest phenomenon of convective summer precipitation in NW Mexico and SW US: the North American Monsoon (NAM) which is the most important source of fresh water for the region. There is a pressing need to better understand especially in times of rapid warming how this monsoonal system is going to respond. Here we explore on the different modes of variability of the monsoonal regime in high-resolution reconstructions of the marine sediment record and their possible controls during the Holocene. The role of the teleconnections between the high and low latitudes climate, the interaction with the ITCZ, ENSO, PDO and AMDO are critical for the understanding of global climate. We produced an XRF record of the relative abundance of Si and Al in high resolution laminated sediments obtained from the western margin of Pescadero basin (24N,108W) in the southern domain of the Gulf of California as proxies of terrigenous input. The laminated nature of this deposits at intermediate depths on its slopes sets the foundation for a potentially good record of changes in the transfer of lithogenic materials between the continent and the ocean in this region. Here we present recently acquired data from the terrigenous fraction on the marine sediment composite record from Pescadero basin (522 m water depth / 220 cm long). We determined the relative abundance of Si and Al from X-ray fluorescence from records that were absolutely dated with the aid and eight radiocarbon ages, which allowed us to produce a continuous record with a decadal temporal resolution. The time series analysis of the entire record of Si and Al show significant periodicities which were further cross-correlated with other paleoclimate proxy

    2015-08-01

    Laser detection and ranging (LADAR)-based systems operating in the Near Infrared (NIR) and Short Wave Infrared (SWIR) have become popular optical sensors for remote sensing, medical, and environmental applications. Sophisticated laser-based radar and weapon systems used for long-range military and astronomical applications need to detect, recognize, and track a variety of targets under a wide spectrum of atmospheric conditions. Infrared APDs play an important role in LADAR systems by integrating the detection and gain stages in a single device. Robust silicon-APDs are limited to visible and very near infrared region ( 3um) infrared photon detection applications. Recently, various research groups (including Ghosh et. al.) have reported SWIR and MWIR HgCdTe APDs on CdZnTe and Si substrates. However, HgCdTe APDs suffer from low breakdown fields due to material defects, and excess noise increases significantly at high electric fields. During the past decade, InAs/GaSb Strain Layer Superlattice (SLS) material system has emerged as a potential material for the entire infrared spectrum because of relatively easier growth, comparable absorption coefficients, lower tunneling currents and longer Auger lifetimes resulting in enhanced detectivities (D*). Band engineering in type II SLS allows us to engineer avalanche properties of electrons and holes. This is a great advantage over bulk InGaAs and HgCdTe APDs where engineering avalanche properties is not possible. The talk will discuss the evolution of superlattice based avalanche photodiodes and some of the recent results on the work being done at Raytheon on SWIR avalanche photodiodes.

    The arid northern Mexico is part of the Sonora and Chihuahua Deserts and both the deserts belong to the North American Desert system. The North American Monsoon (NAM) or Mexican Monsoon refers to the system that brings summer precipitation to arid northern Mexico and southwestern USA. It contributes ca. 70-80% of total annual precipitation along the western slopes of the Sierra Madre Occidental (northern Mexico) and ca. 40-50% of total precipitation in Arizona and New Mexico (southwest USA). High-resolution geochemical data from lacustrine deposits located between 23°N and 31°N (paleolakes La Salada, Babicora and San Felipe) provide spatio-temporal and millennial-scale paleohydrological records related to the dynamics of summer precipitation as well as westerly winter storms over the last glacial period. The inverse relationship between proxy records of runoff into lacustrine basins of northern Mexico and winter precipitation over the southwestern USA indicate that the westerly winter storms had minimal influence south of 30°N and the paleohydrological changes are mainly summer precipitation controlled. The variation in summer season precipitation between 20 and 60 cal. kyr BP was driven by long term changes in summer insolation. During an interval of lower summer insolation (i.e. >60 cal. kyr BP), the higher summer precipitation could be related to the NAM expansion as a result of reduced north hemisphere ice sheets. On a millennial-scale, the region received more than average precipitation during the warm interstadials and vice versa.

    In the summer of 2007, American eels, Anguilla rostrata, from 2 localities on Cape Breton Island, were found to be infected with the swim bladder nematode Anguillicoloides crassus. This is the first documented report of this highly invasive parasite in Canadian waters. More than half of the yellow eels in Mira River (6 of 10), and 1 eel (of 5) from Sydney Harbour were infected. Parasite intensity ranged from 1 to 11 worms per eel. The occurrence of A. crassus at these 2 localities suggests the need for a more extensive survey on the distribution of this exotic parasite in eel populations throughout Cape Breton Island.

    Full Text Available In this paper we explore a speleothem δ18O record from Palestina Cave, North Eastern Peru, at a site on the eastern side of the Andes cordillera, upper Amazon Basin, interpreted as a proxy for South America Summer Monsoon (SASM intensity. This record allows reconstructing SASM activity with 5 yr time resolution over the last 1600 yr, spanning two major periods of climate variability: the Medieval Climate Anomaly (MCA; 900–1200 AD and Little Ice Age (LIA 1400–1850 AD recognized as periods of decrease and increase SASM activity respectively. Time series and wavelet analyses reveal decadal to multidecadal frequencies. Our results suggest that Atlantic Multidecadal Oscillation mode (AMO plays an important role for SASM modulation on multidecadal scale (~65 yr, especially over dry periods such as observed during MCA. Frequencies of 8 and 25 yr simultaneously with multidecadal signal (65 yr are found over the LIA. and suggest that those modes could be related to North Atlantic Oscillation (NAO and Interdecadal Pacific Oscillation mode (IPO. Comparison with other South American Paleoprecipitation records shows that the Atlantic and Pacific decadal to multidecadal variability and their teleconnections play an important role in the intensity and the regional patterns of rainfall distribution during the last 1600 yr.

    Full Text Available Wolbachia are endosymbiotic bacteria that commonly infect arthropods, inducing certain phenotypes in their hosts. So far, no endemic South American species of terrestrial isopods have been investigated for Wolbachia infection. In this work, populations from two species of Balloniscus (B. sellowii and B. glaber were studied through a diagnostic PCR assay. Fifteen new Wolbachia 16S rDNA sequences were detected. Wolbachia found in both species were generally specific to one population, and five populations hosted two different Wolbachia 16S rDNA sequences. Prevalence was higher in B. glaber than in B. sellowii, but uninfected populations could be found in both species. Wolbachia strains from B. sellowii had a higher genetic variation than those isolated from B. glaber. AMOVA analyses showed that most of the genetic variance was distributed among populations of each species rather than between species, and the phylogenetic analysis suggested that Wolbachia strains from Balloniscus cluster within Supergroup B, but do not form a single monophyletic clade, suggesting multiple infections for this group. Our results highlight the importance of studying Wolbachia prevalence and genetic diversity in Neotropical species and suggest that South American arthropods may harbor a great number of diverse strains, providing an interesting model to investigate the evolution of Wolbachia and its hosts.

  18. Coastal dunefields of south Brazil as a record of climatic changes in the South American Monsoon System

    Southern Brazil coastal dunefields are undergoing a stabilization process that appears to be influenced by climate change. Although this process is relatively well known in the literature, the precise climatic mechanisms involved were not fully understood until now. Here, we propose a new method for integrating meteorological data with dunefield morphology analyses by remote sensing to better understand the impacts of recent climate change on dunefield dynamics. Based on this approach, three successive morphological phases were identified for the Santa Catarina central coast dunefields since 1938: (i) increased sand saturation; (ii) reduced sand saturation with consequent accelerated dune migration; and (iii) decelerated dune migration with trends of stabilization by the vegetation cover. For the coastal dunefields of southern Brazil, the stabilization process can be explained mechanistically by an increase in precipitation and decrease of wind power, both of which were correlated with the intensification of the South American Monsoon System.

    The successful implementation of clinical information systems is difficult. In examining the reasons and potential solutions for this problem, the medical informatics community may benefit from the lessons of a rich body of software engineering and management literature about the failure of software projects. Based on previous studies, we present a conceptual framework for understanding the risk factors associated with large-scale projects. However, the vast majority of existing literature is based on large, enterprise-wide systems, and it unclear whether those results may be scaled down and applied to smaller projects such as departmental medical information systems. To examine this issue, we discuss the case study of a delayed electronic medical record implementation project in a small specialty practice at Columbia-Presbyterian Medical Center. While the factors contributing to the delay of this small project share some attributes with those found in larger organizations, there are important differences. The significance of these differences for groups implementing small medical information systems is discussed. PMID:12463804

    Topography has a strong impact on atmospheric circulation and precipitation patterns and is a key element in reconstructing the dynamics of mountain building processes. The topographic evolution of the world's major orogens remains one of the most important questions when discussing the interactions among tectonics, climate, and Earth surface processes. Here, we focus on the spatial and temporal development of topography and relief in the western North American Cordillera and how changes in the topography may have affected precipitation patterns and vice versa. In this context, we sampled more than 20 sections in Eocene to Oligocene terrestrial (intermontane?) basins (Chumstick, Swauk, and Chuckanut) in western and central Washington (USA) to the W and E of the modern Cascades. Oxygen isotope analysis of pedogenic carbonate in these sections allows us to reconstruct the isotopic composition of ancient soilwater or groundwater, and ultimately precipitation. Oxygen isotope measurements of pedogenic concretions and calcic horizons interestingly yield uniformly low δ18O values of 10 to 13‰ SMOW despite the proximity of all sections to the Pacific moisture source. These extremely low oxygen isotope values can result from (1) highly 18O-depleted meteoric waters (soil- or groundwater), (2) burial diagenesis at moderate temperatures and interaction with 18O-depleted (ground)water, and (3) high burial temperatures and and exchange with basins brines. Vitrinite reflectance data and preservation of primary soil structures such as rootlets, root casts, burrows, or even preserved wood fragments clearly show that some of the low-d18O sections were not affected by high degrees of burial diagenesis. Thus, we believe that the primary isotopic signal of ancient soil- or groundwater is preserved at least in parts (if not in all) of these basins. Low δ18O values of pedogenic carbonate require highly 18O-depleted meteoric water, which in turn, would require high elevation either at

    Cave stalagmite records show strong evidence of abrupt changes in summer monsoons during Heinrich events, but we lack rigorous constraints on the amount of wetting or drying occurring in monsoon regions. Studies on shoreline deposits of closed-basin lakes can establish quantitative bounds on water balance changes through mapping-based estimates of lake volume variations. We present new dating constraints on lake level variations in Agua Caliente I and Laguna Loyoques, two closed-basin, high-altitude paleolakes on the Altiplano-Puna plateau of the Central Andes (23.1°S, 67.4°W, 4250 masl). Because this area receives >70% of its total annual precipitation during austral summer, the region is ideally suited to capture a pure response to changes in the South American summer monsoon (SASM). The plateau is home to several small (modern. Hydrologic modeling constrained by paleotemperature estimates is used to provide bounds for these past precipitation changes. We also tentatively explore physical mechanisms linking Heinrich events and the regional hydroclimate by comparing freshwater hosing experiments and transient climate simulations. Our results in Agua Caliente I and Laguna Loyoques act as a proof of concept, and lend us confidence in expanding our U-Th work to other shoreline tufas in the surrounding region to produce a more detailed, spatiotemporal record of water balance changes in South America.

    Lake sediment oxygen isotope records (calcium carbonate-δ18O) in the western North American Cordillera developed during the past decade provide substantial evidence of Pacific ocean-atmosphere forcing of hydroclimatic variability during the Holocene. Here we present an overview of 18 lake sediment δ18O records along with a new compilation of lake water δ18O and δ2H that are used to characterize lake sediment sensitivity to precipitation-δ18O in contrast to fractionation by evaporation. Of the 18 records, 14 have substantial sensitivity to evaporation. Two records reflect precipitation-δ18O since the middle Holocene, Jellybean and Bison Lakes, and are geographically positioned in the northern and southern regions of the study area. Their comparative analysis indicates a sequence of time-varying north-south precipitation-δ18O patterns that is evidence for a highly non-stationary influence by Pacific ocean-atmosphere processes on the hydroclimate of western North America. These observations are discussed within the context of previous research on North Pacific precipitation-δ18O based on empirical and modeling methods. The Jellybean and Bison Lake records indicate that a prominent precipitation-δ18O dipole (enriched-north and depleted-south) was sustained between ~ 3.5 and 1.5 ka, which contrasts with earlier Holocene patterns, and appears to indicate the onset of a dominant tropical control on North Pacific ocean-atmosphere dynamics. This remains the state of the system today. Higher frequency reversals of the north-south precipitation-δ18O dipole between ~ 2.5 and 1.5 ka, and during the Medieval Climate Anomaly and the Little Ice Age, also suggest more varieties of Pacific ocean-atmosphere modes than a single Pacific Decadal Oscillation (PDO) type analogue. Results indicate that further investigation of precipitation-δ18O patterns on short (observational) and long (Holocene) time scales is needed to improve our understanding of the processes that drive

  3. Improving the global SST record: estimates of biases from engine room intake SST using high quality satellite data

    Sea Surface Temperature (SST) is the marine component of the global surface temperature record, a primary metric of climate change. SST observations from ships form one of the longest instrumental records of surface marine climate. However, over the years several different methods of measuring SST have been used, each with different bias characteristics. The estimation of systematic biases in the SST record is critical for climatic decadal predictions, and uncertainties in long-term trends are expected to be dominated by uncertainties in biases introduced by changes of instrumentation and measurement practices. Although the largest systematic errors in SST observations relate to the period before about 1940, where SST measurements were mostly made using buckets, there are also issues with modern data, in particular when the SST reported is the temperature of the engine-room cooling water intake (ERI). Physical models for biases in ERI SSTs have not been developed as the details of the individual setup on each ship are extremely important, and almost always unknown. Existing studies estimate that the typical ERI biases are around 0.2°C and most estimates of the mean bias fall between 0.1°C and 0.3°C, but there is some evidence of much larger differences. However, these analyses provide only broad estimates, being based only on subsamples of the data and ignoring ship-by-ship differences. Here we take advantage of a new, high spatial resolution, gap-filled, daily SST for the period 1992-2010 from the European Space Agency Climate Change Initiative (ESA CCI) for SST dataset version 1.1. In this study, we use a Bayesian statistical model to characterise the uncertainty in reports of ERI SST for individual ships using the ESA CCI SST as a reference. A Bayesian spatial analysis is used to model the differences of the observed SST from the ESA CCI SST for each ship as a constant offset plus a function of the climatological SST. This was found to be an important term

    The purpose of this research study was to examine, for undergraduate women of various Asian American ethnic backgrounds, the influence of background contextual and college environment factors on their sense of academic self-efficacy and achievement in science, technology, engineering, and mathematics (STEM) majors. Social cognitive career theory and its critiques provided a theoretical foundation for relationships from past performance, socioeconomic status, acculturation, and college environment variables (compositional diversity, racial climate, gendered climate, academic peer support), to academic self-efficacy and achievement. Data were collected through an online survey. Instrumentation included the scales of Language, Identity, and Behavioral Acculturation; Gender Discrimination; Faculty and Classroom Behavior; Interactions with Peers; and Academic Milestones Self-efficacy. The participants were 228 Asian American undergraduate women in STEM at a large public, doctoral research extensive university on the east coast; the response rate was 51%. In three MANOVAs for nine social cognitive career variables, four ethnic groups (East, South, Southeast, and Multi-ethnic Asian American) significantly differed only on socioeconomic status. In path analysis, the initial model was not a good fit and was rejected. The model was respecified through statistical and theoretical evaluation, tested in exploratory analysis, and considered a good fit. The respecified model explained 36% of semester GPA (achievement) and 28% of academic self-efficacy. The academic achievement of Asian American women in STEM was related to past performance, background contextual factors, academic self-efficacy, academic peer support, and gendered climate. The strongest direct influence on achievement was academic self-efficacy followed by past performance. The total effect of Asian acculturation on achievement was negative and the total effect of American acculturation on achievement was not

    Insolation forcing of tropical climate at precessional timescales appears to be a widespread phenomenon in South America. This could reflect the influence of local insolation changes on rainfall and evaporation, and hence migration of the marine intertropical convergence zone (ITCZ) and its terrestrial expression, the South American summer monsoon. However, modern interannual climate variability in South America is also closely linked to ocean-atmosphere interactions in the tropical Pacific expressed primarily as the El Niño-Southern Oscillation (ENSO). The timing of climate changes in the Northern and Southern Hemisphere tropics is one way to distinguish between these mechanisms. Precessional forcing of Atlantic ITCZ migration would cause changes in the northern and southern hemispheres that are opposite in sign. In contrast, ENSO variability has a similar character in the Andean regions of both hemispheres. Here we develop a new terrestrial paleoclimate record in the northern tropics of South America. Lake level fluctuations from Laguna Blanca, located in the Venezuelan Andes, exhibit arid-humid intervals during the past 10,000 years that occur at the same time as those in the neotropics of both hemispheres. This pattern suggests that millennial-scale climate trends in Andean South America may reflect changes in the mean state and variability of the equatorial Pacific Ocean.

    The Northern Cordillera of the Dominican Republic records the (oblique) subduction and collisional processes occurred between the Caribbean and North-American plates during Upper Cretaceous to Lower Paleogene times. The boundary between these two plates can be traced within this range disrupted by an Upper Paleogene to present intense left-lateral strike-slip tectonism, onset after collision. In the western part of the range this boundary might be defined by the Camu fault. In the coastal area of Puerto Plata, located on the northern block of the Camu fault, basement rocks belonging to the subducting plate (the Puerto Plata Basement Complex) and several related units probably formed in an accretionary prism, preserve in a large (300 km2) outcrop of chaotic formations presumably formed (and exhumed) during collision. They include from broken formations and tectonic melanges to olistostromes and other coeval sedimentary deposits. The Puerto Plata Basement Complex (PPBC) consists of highly faulted and dismembered blocks formed by discontinuous but sometimes coherent outcrops of serpentinized or massive peridotite, pods of ultramafic cumulates, massive or banded gabbros and Los Caños Fm, a thick sequence of gross bedded volcaniclastic material with interbedded basaltic (sometimes pillowed) or andesitic flows. All these rocks bear low grade metamorphism and lack a general deformation fabric apart from occasional transformation to mylonites due to localized shearing. The PPBC has been interpreted as a fragment of oceanic crust, belonging to the subducting (North-American) slab that has been exhumed as a tectonic melange or a broken complex. The Imbert Fm, of Palaeocene-Eocene age, is formed by a well bedded succession of white very fine grained porcelaneous tuffs, with eventual intercalations of cherts, limestones and marls that, towards the lower part, is interbedded with volcanic-derived graywackes and limolites, and more occasionally, thick beds of conglomerates and

    Full Text Available El objetivo principal de la presente investigación consiste en analizar el Factor de Impacto Web (FIW de los Archivos Universitarios Latinoamericanos durante un periodo temporal de seis meses utilizando dos herramientas distintas para calcularlo: Google y Altavista. Los resultados demuestran que no existe correlación entre ambos motores a la hora de calcular el FIW de los Arhivos en cuestión, lo que permite concluir que el uso de distintas herramientas o motores utilizados para calcular el FIW interfiere en los resultados obtenidos, por lo que hay que tener cuidado al momento de establecer un ranking de calidad de los AUL, según su FIW.The main objective of this research is to analyze the Web Impact Factor (WIF of the Latin American University Archives during a six month period using two different analytical tools: Google and Altavista. The results show no correlation between the two engines when calculating the WIF of these Archives, allowing us to conclude that the use of different tools or engines to calculate the WIF affects the results, so that we must be careful when setting up a quality ranking of the LUA, according to their WIF.

    Seismic crisis occurred in Lorca (Murcia) on 11th May 2011 originated an important number of accelerograms recorded in the IGN stations. The analysis of uniformly computed parameters has produced interesting results for Earthquake Engineering, in particular those recorded in Lorca. Strong ground motion has been specially observed in the horizontal component perpendicular to the Alhama de Murcia fault, at the origin of the earthquake. Values of PGA= 0.37g and CAV= 0.27gs seems to be compensated by a short duration of the motion producing a macro seismic Intensity not greater than VII in Lorca. The contribution of near field component of ground motion due to the rupture propagation to and under the Lorca town was shown on acceleration, velocity and displacement time series and also on elastic response spectra.

    Clinical software systems are becoming ubiquitous. A growing literature documents how these systems can improve health care delivery, but concerns about patient safety must now be formally addressed. In 1996, the U.S. Food and Drug Administration (FDA) called for discussions on regulation of software programs as medical devices. In response, a consortium of organizations dedicated to improving health care through information technology developed recommendations for the responsible regulation and monitoring of clinical software systems by users, vendors, and regulatory agencies. These recommendations were revised and approved by the American Medical informatics Association Public Policy Committee and Board. Other organizations reviewed, modified, and approved the recommendations, and the Boards of Directors of most of the organizations in the consortium endorsed the guidelines. The consortium proposes four categories of clinical system risk and four classes of monitoring and regulatory action that can be applied on the basis of the risk level. The consortium recommends that most clinical software systems be supervised locally and that developers of health care information systems adopt a code of good business practices. Budgetary and other constraints limit the type and number of systems that the FDA can regulate effectively; therefore, the FDA should exempt most clinical software systems and focus on systems that pose high clinical risk and provide limited opportunity for competent human intervention.

    Cottledge, Michael Christopher

    Objective of the Study: The objective of this research study was to investigate whether an association exists between teacher demographic factors (years of teaching experience and gender), 2 educational factors (certification type and certification pathway) and the percent passing rate of tenth grade African American male students on the 2010 science TAKS. Answers to the following questions were sought: 1. Is there an association between teacher demographic factors and the percent passing rate of their tenth grade African American male students on the 2010 science TAKS? 2. Is there an association between teacher educational factors and the percent passing rate of their tenth grade African American male students on the 2010 science TAKS? 3. Is there an association between teacher demographic factors, educational factors and the percent passing rate of their tenth grade African American male students on the 2010 science TAKS? Status of the Question: According to the Bureau of Labor Statistics (BLS), science and engineering jobs in the U.S. have increased steadily over recent years and by the year 2016 the number of STEM (Science, Technology, Engineering and Math) jobs will have grown by more than 21 percent. This increase in science and engineering jobs will double the growth rate of all other workforce sectors combined. The BLS also reports that qualified minority applicants needed to fill these positions will be few and far between. African Americans, Latinos, and other minorities constitute 24 percent of the U.S. population but only 13 percent of college graduates and just 10 percent of people with college degrees who work in science and engineering (Education Trust, 2009). Drawing on the above information, I proposed the following hypotheses to the research questions: H01: There will be no significant statistical association between the demographic factors teacher gender and years of teaching experience and the percent passing rate of their tenth grade African

  10. Making magnetic recording commercial: 1920-1955

    Science.gov (United States)

    Clark, Mark H.

    1999-03-01

    Although magnetic recording had been invented in 1898, it was not until the late 1920s that the technology was successfully marketed to the public. Firms in Germany, the United Kingdom, and the United States developed and sold magnetic recorders for specialized markets in broadcasting and telephone systems through the 1930s. The demands of World War II considerably expanded the use of magnetic recording, and with the end of the war, firms in the United States sought to bring magnetic recording to home and professional music recording. Using a combination of captured German technology and American wartime research, American companies such as Ampex, Magnecord, 3M, the Brush Development Company, and others created a vast new industry. By the mid-1950s, magnetic recording was firmly established as a method for recording both sound and data.

    Full Text Available Dan Belletti1, Christopher Zacker1, C Daniel Mullins21Novartis Pharmaceuticals Corporation, East Hanover, NJ, USA; 2University of Maryland School of Pharmacy, Baltimore, MD, USAAbstract: Health information technology (HIT is engineered to promote improved quality and efficiency of care, and reduce medical errors. Healthcare organizations have made significant investments in HIT tools and the electronic medical record (EMR is a major technological advance. The Department of Veterans Affairs was one of the first large healthcare systems to fully implement EMR. The Veterans Health Information System and Technology Architecture (VistA began by providing an interface to review and update a patient’s medical record with its computerized patient record system. However, since the implementation of the VistA system there has not been an overall substantial adoption of EMR in the ambulatory or inpatient setting. In fact, only 23.9% of physicians were using EMRs in their office-based practices in 2005. A sample from the American Medical Association revealed that EMRs were available in an office setting to 17% of physicians in late 2007 and early 2008. Of these, 17% of physicians with EMR, only 4% were considered to be fully functional EMR systems. With the exception of some large aggregate EMR databases the slow adoption of EMR has limited its use in outcomes research. This paper reviews the literature and presents the current status of and forces influencing the adoption of EMR in the office-based practice, and identifies the benefits, limitations, and overall value of EMR in the conduct of outcomes research in the US.Keywords: electronic medical records, health information technology, medical errors

    The United States Pharmacopeial Convention, Inc., is recognized by federal law and by most state boards of pharmacy as the official group for setting the standards for pharmaceuticals and pharmacy practice, including compounding. The standards of United States Pharmacopeia Chapter 795 require that a pharmacy maintain records on a compounded preparation, including the formulation record, and a Material Safety Data Sheets file. The American Society of Health-Systems Pharmacists' guidelines require that hospital pharmacy departments maintain at least four sets of records in the compounding area: (1) compounding formulas and procedures, (2) compounding logs of all compounded preparations, including batch records and sample batch labels, (3) equipment maintenance records, and (4) a record of ingredients purchased, including cerificates of analysis and Material Saftey Data Sheets. Hospital compounding records may be inspected by any of several outside organizations, including state boards of pharmacy, third-party payers, the Joint Commission on Accreditaion of Healthcare Organizations, the Drug Enforcement Agency, and attorneys. With the existing standards and guidelines in place and the importance of documentation unquestionable, a record of pharmacy activites should be maintained in a compounding pharmacy so that preparations can be replicated consistently, the history of each ingredient traced, equipment maintenance and calibration verified, and compounding procedures evaluated easily.

    2002-12-01

    Full Text Available The article describes a troubled history of eugenics in the US, from its beginnings at the end of the 19th century, through the whole of the 20th. It is a part of a larger historical study on eugenics. It focuses on Davenport, Laughlin, Estabrook and the Eugenic Record Office, on the early racist eugenicists like Grant and Ross, and on sterilization legislation in the twenties and thirties. The intention however was to put the historical debate into a contemporary context, or at least to show that some eugenic ideas have lived long after everybody thought they were dead. There are some hints and quotations that show it might still be possible to misuse sterilisation in the US today.

    Bertram, H. Neal

    1994-04-01

    This book is designed to give the student a fundamental, in-depth understanding of all the essential features of the magnetic recording process for both high density disk and tape recording. The book provides a thorough grounding in four basic areas of magnetic recording: structure and fields of heads and media, the replay process, the recording process, and medium noise analysis. Besides the fundamental issues, key systems questions of nonlinearities, overwrite, side track phenomena, error rate estimates as well as comparisons of MR and inductive heads will be discussed. The student will be able to use the information presented to design and analyze key experiments for head and medium evaluation as well as for overall system performance decisions. A parallel treatment of time and frequency response will enable the student to evaluate signal processing schemes. The book is intended either for senior-year undergraduates or first-year graduates. It assumes that the reader has had basic introductory electrical engineering or physics courses such as electricity and magnetism and applied mathematics.

  5. Oxygen Isotopes in Tree Rings: A 345 Year Record of Precipitation in Amazonia

    Science.gov (United States)

    Jenkins, H. S.; Baker, P. A.; Evans, M. N.

    2008-12-01

    The Amazon basin is one of the world's key centers of atmospheric convection and acts as an engine for global hydrologic circulation. Despite its importance, a paucity of high resolution climate data exists for this region, in large part due to a poor instrumental record. The oxygen isotopic measurement of meteoric water has been used extensively to reconstruct past temperatures derived from ice cores, corals, and tree rings but is only recently recognized as a precipitation proxy in the tropics. Here we present a continuous, highly resolved (intra-annual), 345 year oxygen isotopic record from the Madre de Dios department in Southeastern Peru. Using tropical hardwood species Dipteryx micrantha, we present oxygen (and carbon) isotopic data from digested tree ring cellulose. We also present some of the first intra-annual (early wood versus late wood) isotopic data on this old growth tropical species. We demonstrate the utility of Amazon tropical tree rings to accurately record rainfall. We also identify that this meteoric water was delivered to the region via the South American Low-level Jet (SALLJ), which develops over the Atlantic and is the major water source during the South American Summer Monsoon.

  6. Engineering and Software Engineering

    Science.gov (United States)

    Jackson, Michael

    The phrase ‘software engineering' has many meanings. One central meaning is the reliable development of dependable computer-based systems, especially those for critical applications. This is not a solved problem. Failures in software development have played a large part in many fatalities and in huge economic losses. While some of these failures may be attributable to programming errors in the narrowest sense—a program's failure to satisfy a given formal specification—there is good reason to think that most of them have other roots. These roots are located in the problem of software engineering rather than in the problem of program correctness. The famous 1968 conference was motivated by the belief that software development should be based on “the types of theoretical foundations and practical disciplines that are traditional in the established branches of engineering.” Yet after forty years of currency the phrase ‘software engineering' still denotes no more than a vague and largely unfulfilled aspiration. Two major causes of this disappointment are immediately clear. First, too many areas of software development are inadequately specialised, and consequently have not developed the repertoires of normal designs that are the indispensable basis of reliable engineering success. Second, the relationship between structural design and formal analytical techniques for software has rarely been one of fruitful synergy: too often it has defined a boundary between competing dogmas, at which mutual distrust and incomprehension deprive both sides of advantages that should be within their grasp. This paper discusses these causes and their effects. Whether the common practice of software development will eventually satisfy the broad aspiration of 1968 is hard to predict; but an understanding of past failure is surely a prerequisite of future success.

  10. Human reliability guidance - How to increase the synergies between human reliability, human factors, and system design and engineering. Phase 2: The American Point of View - Insights of how the US nuclear industry works with human reliability analysis

    International Nuclear Information System (INIS)

    The main goal of this Nordic Nuclear Safety Research Council (NKS) project is to produce guidance for how to use human reliability analysis (HRA) to strengthen overall safety. The project consists of two substudies: The Nordic Point of View - A User Needs Analysis, and The American Point of View - Insights of How the US Nuclear Industry Works with HRA. The purpose of the Nordic Point of View study was a user needs analysis that aimed to survey current HRA practices in the Nordic nuclear industry, with the main focus being to connect HRA to system design. In this study, 26 Nordic (Swedish and Finnish) nuclear power plant specialists with research, practitioner, and regulatory expertise in HRA, PRA, HSI, and human performance were interviewed. This study was completed in 2009. This study concludes that HRA is an important tool when dealing with human factors in control room design or modernizations. The Nordic Point of View study showed areas where the use of HRA in the Nordic nuclear industry could be improved. To gain more knowledge about how these improvements could be made, and what improvements to focus on, the second study was conducted. The second study is focused on the American nuclear industry, which has many more years of experience with risk assessment and human reliability than the Nordic nuclear industry. Interviews were conducted to collect information to help the author understand the similarities and differences between the American and the Nordic nuclear industries, and to find data regarding the findings from the first study. The main focus of this report is to identify potential HRA improvements based on the data collected in the American Point of View survey. (Author)

    2016-06-01

    Estuaries around the world are in a state of decline following decades or more of overfishing, pollution, and climate change. Oysters (Ostreidae), ecosystem engineers in many estuaries, influence water quality, construct habitat, and provide food for humans and wildlife. In North America's Chesapeake Bay, once-thriving eastern oyster (Crassostrea virginica) populations have declined dramatically, making their restoration and conservation extremely challenging. Here we present data on oyster size and human harvest from Chesapeake Bay archaeological sites spanning ∼3,500 y of Native American, colonial, and historical occupation. We compare oysters from archaeological sites with Pleistocene oyster reefs that existed before human harvest, modern oyster reefs, and other records of human oyster harvest from around the world. Native American fisheries were focused on nearshore oysters and were likely harvested at a rate that was sustainable over centuries to millennia, despite changing Holocene climatic conditions and sea-level rise. These data document resilience in oyster populations under long-term Native American harvest, sea-level rise, and climate change; provide context for managing modern oyster fisheries in the Chesapeake Bay and elsewhere around the world; and demonstrate an interdisciplinary approach that can be applied broadly to other fisheries.

    In the sixties, CERN’s Fellows were but a handful of about 50 young experimentalists present on site to complete their training. Today, their number has increased to a record-breaking 500. They come from many different fields and are spread across CERN’s different activity areas.   “Diversifying the Fellowship programme has been the key theme in recent years,” comments James Purvis, Head of the Recruitment, Programmes and Monitoring group in the HR Department. “In particular, the 2005 five-yearly review introduced the notion of ‘senior’ and ‘junior’ Fellowships, broadening the target audience to include those with Bachelor-level qualifications.” Diversification made CERN’s Fellowship programme attractive to a wider audience but the number of Fellows on site could not have increased so much without the support of EU-funded projects, which were instrumental in the growth of the programme. ...

  11. Close relationships between Asian American and European American college students.

    Science.gov (United States)

    Chen, C; Edwards, K; Young, B; Greenberger, E

    2001-02-01

    The authors examined attitudes and behaviors regarding close relationships between European and Asian Americans, with a particular emphasis on 5 major subgroups of Asian Americans (Chinese, Japanese, Korean, Vietnamese, and Filipino Americans). Participants were 218 Asian American college students and 171 European American college students attending a culturally diverse university. The European Americans did not differentiate among the various subgroups of Asian Americans. Their attitudes regarding close relationships were less positive toward Asian Americans than toward Mexican and African Americans, a finding contrary to the prediction of social exchange theory (H. Tajfel, 1975). In contrast to the European Americans' view of homogeneity among Asian Americans, the 5 major subgroups of Asian Americans expressed a distinctive hierarchy of social preference among themselves. Results are discussed in terms of their implications for future research on interethnic relations involving Asian Americans. PMID:11294169

    Researching evermore abstract and powerful ways of composing programs is the meat of software engineering for half a century. Important early steps were subroutines (to encapsulate actions) and records (to encapsulate data). A large step forward came with the introduction of the object-oriented concepts (classes, subclasses and virtual methods) where classes can encapsulate both data and behaviors in a very powerful, but still flexible, way. For a long time, these concepts dominated the scene...

  16. Engineering graphics theoretical foundations of engineering geometry for design

    CERN Document Server

    Brailov, Aleksandr Yurievich

    2016-01-01

    This professional treatise on engineering graphics emphasizes engineering geometry as the theoretical foundation for communication of design ideas with real world structures and products. It considers each theoretical notion of engineering geometry as a complex solution of direct- and inverse-problems of descriptive geometry and each solution of basic engineering problems presented is accompanied by construction of biunique two- and three-dimension models of geometrical images. The book explains the universal structure of formal algorithms of the solutions of positional, metric, and axonometric problems, as well as the solutions of problems of construction in developing a curvilinear surface. The book further characterizes and explains the added laws of projective connections to facilitate construction of geometrical images in any of eight octants. Laws of projective connections allow constructing the complex drawing of a geometrical image in the American system of measurement and the European system of measu...

  18. Summary Record

    International Nuclear Information System (INIS)

    The first workshop of the OECD/NRC Benchmark based on NUPEC BWR Full-size Fine-mesh Bundle Tests (BFBT) was held on 4 October 2004. The workshop was hosted by the Japan Nuclear Energy Safety (JNES) Organization. The BFBT Benchmark is sponsored by the US Nuclear Regulatory Commission (NRC), the OECD, and the Nuclear Engineering Program (NEP) of the Pennsylvania State University. The experimental data was produced during a measurement campaign by the NUPEC, Japan, and sponsored by the Japan Ministry of Economy, Trade and Industry (METI). This international benchmark, based on the NUPEC database, encourages advancement in this un-investigated field of two-phase flow theory with very important relevance to the nuclear reactor's safety margins evaluation. Considering the immaturity of the theoretical approach, the benchmark specification is being designed so that it systematically assesses and compares the participants' numerical models on the prediction of detailed void distributions and critical powers. Furthermore, the following points are kept in mind while the benchmark specification is being established. As concerns the numerical model of void distributions, no sound theoretical approach that can be applied to a wide range of geometrical and operating conditions has been developed. In the past decade, experimental and computational technologies have improved tremendously through the study of the two-phase flow structure. Over the next decade, it can be expected that mechanistic approaches will be more widely applied to the complicated two-phase fluid phenomena inside fuel bundles. The development of truly mechanistic models for critical power prediction is currently underway. These models must include elementary processes such as void distributions, droplet deposit, liquid film entrainment, etc. The BFBT benchmark consists of two parts (phases), each part consisting of different exercises: - Phase 1 Void Distribution Benchmark: Exercise 1: Steady-state sub

    1999-01-01

    Trends in American society are changing the role of women in science and engineering, but all the elements in our society change at different rates. Women, like men, must choose during their teenage years to continue their training in math or science, or they close the door that can lead them to futures in the interesting and satisfying fields of science and engineering. The key is to keep girls involved in the hard sciences through the adolescent crisis. Many mentoring and outreach programs exist to help young women cross this threshold. These programs include hands-on science experiences, mentoring or putting young women in contact with women scientists and engineers, and internships, Viewpoints and histories of contemporary women engineers are discussed.

  1. African-American males in computer science---Examining the pipeline for clogs

    Science.gov (United States)

    Stone, Daryl Bryant

    The literature on African-American males (AAM) begins with a statement to the effect that "Today young Black men are more likely to be killed or sent to prison than to graduate from college." Why are the numbers of African-American male college graduates decreasing? Why are those enrolled in college not majoring in the science, technology, engineering, and mathematics (STEM) disciplines? This research explored why African-American males are not filling the well-recognized industry need for Computer Scientist/Technologists by choosing college tracks to these careers. The literature on STEM disciplines focuses largely on women in STEM, as opposed to minorities, and within minorities, there is a noticeable research gap in addressing the needs and opportunities available to African-American males. The primary goal of this study was therefore to examine the computer science "pipeline" from the African-American male perspective. The method included a "Computer Science Degree Self-Efficacy Scale" be distributed to five groups of African-American male students, to include: (1) fourth graders, (2) eighth graders, (3) eleventh graders, (4) underclass undergraduate computer science majors, and (5) upperclass undergraduate computer science majors. In addition to a 30-question self-efficacy test, subjects from each group were asked to participate in a group discussion about "African-American males in computer science." The audio record of each group meeting provides qualitative data for the study. The hypotheses include the following: (1) There is no significant difference in "Computer Science Degree" self-efficacy between fourth and eighth graders. (2) There is no significant difference in "Computer Science Degree" self-efficacy between eighth and eleventh graders. (3) There is no significant difference in "Computer Science Degree" self-efficacy between eleventh graders and lower-level computer science majors. (4) There is no significant difference in "Computer Science Degree

  8. Fluids engineering

    International Nuclear Information System (INIS)

    Fluids engineering has played an important role in many applications, from ancient flood control to the design of high-speed compact turbomachinery. New applications of fluids engineering, such as in high-technology materials processing, biotechnology, and advanced combustion systems, have kept up unwaining interest in the subject. More accurate and sophisticated computational and measurement techniques are also constantly being developed and refined. On a more fundamental level, nonlinear dynamics and chaotic behavior of fluid flow are no longer an intellectual curiosity and fluid engineers are increasingly interested in finding practical applications for these emerging sciences. Applications of fluid technology to new areas, as well as the need to improve the design and to enhance the flexibility and reliability of flow-related machines and devices will continue to spur interest in fluids engineering. The objectives of the present seminar were: to exchange current information on arts, science, and technology of fluids engineering; to promote scientific cooperation between the fluids engineering communities of both nations, and to provide an opportunity for the participants and their colleagues to explore possible joint research programs in topics of high priority and mutual interest to both countries. The Seminar provided an excellent forum for reviewing the current state and future needs of fluids engineering for the two nations. With the Seminar ear-marking the first formal scientific exchange between Korea and the United States in the area of fluids engineering, the scope was deliberately left broad and general

Partimos de la hipótesis que el concepto "América Latina" es connotado a priori como "subversivo, "comunista", "revolucionario". Lo anterior podría explicar la profusión de informes de inteligencia sobre las ciencias sociales latinoamericanas de los años sesenta y setenta, así como también los centros de estudio, las revistas, e incluso la canción popular encontrados en el Archivo de la ex Dirección de Inteligencia de la Policía de la Provincia de Buenos Aires [DIPBA], fondo privilegiado para la reconstrucción sobre las formas y significados de la construcción de la categoría "delincuente subversivo" por parte de los servicios de inteligencia sobre el campo cultural argentino.The paper aims to trace, to reconstruct and to analyze the records of the Intelligence Services regarding the production of Latin-American social sciences in the period 1976-1983. The object "Latin America" is to the services of intelligence a priori associated with and connoting "communist", "revolutionary" or "subversive". All the above led to an exhaustive work of exegesis and research on the production of Latin-American Social Sciences describing a double process: introducing professionalism in politics and political radicalization. The documents found in the Archive of the former Direction of Intelligence of the Police of the Province of Buenos Aires [DIPBA] -(containing reports of other services of intelligence allow to infer the importance and the degree of "danger" that the dictatorships attributed to this production.

  1. Advanced Natural Gas Reciprocating Engine(s)

    Energy Technology Data Exchange (ETDEWEB)

    Kwok, Doris; Boucher, Cheryl

    2009-09-30

    Energy independence and fuel savings are hallmarks of the nation’s energy strategy. The advancement of natural gas reciprocating engine power generation technology is critical to the nation’s future. A new engine platform that meets the efficiency, emissions, fuel flexibility, cost and reliability/maintainability targets will enable American manufacturers to have highly competitive products that provide substantial environmental and economic benefits in the US and in international markets. Along with Cummins and Waukesha, Caterpillar participated in a multiyear cooperative agreement with the Department of Energy to create a 50% efficiency natural gas powered reciprocating engine system with a 95% reduction in NOx emissions by the year 2013. This platform developed under this agreement will be a significant contributor to the US energy strategy and will enable gas engine technology to remain a highly competitive choice, meeting customer cost of electricity targets, and regulatory environmental standard. Engine development under the Advanced Reciprocating Engine System (ARES) program was divided into phases, with the ultimate goal being approached in a series of incremental steps. This incremental approach would promote the commercialization of ARES technologies as soon as they emerged from development and would provide a technical and commercial foundation of later-developing technologies. Demonstrations of the Phase I and Phase II technology were completed in 2004 and 2008, respectively. Program tasks in Phase III included component and system development and testing from 2009-2012. Two advanced ignition technology evaluations were investigated under the ARES program: laser ignition and distributed ignition (DIGN). In collaboration with Colorado State University (CSU), a laser ignition system was developed to provide ignition at lean burn and high boost conditions. Much work has been performed in Caterpillar’s DIGN program under the ARES program. This work

  2. Software engineering methodologies and tools

    Science.gov (United States)

    Wilcox, Lawrence M.

    1993-01-01

    Over the years many engineering disciplines have developed, including chemical, electronic, etc. Common to all engineering disciplines is the use of rigor, models, metrics, and predefined methodologies. Recently, a new engineering discipline has appeared on the scene, called software engineering. For over thirty years computer software has been developed and the track record has not been good. Software development projects often miss schedules, are over budget, do not give the user what is wanted, and produce defects. One estimate is there are one to three defects per 1000 lines of deployed code. More and more systems are requiring larger and more complex software for support. As this requirement grows, the software development problems grow exponentially. It is believed that software quality can be improved by applying engineering principles. Another compelling reason to bring the engineering disciplines to software development is productivity. It has been estimated that productivity of producing software has only increased one to two percent a year in the last thirty years. Ironically, the computer and its software have contributed significantly to the industry-wide productivity, but computer professionals have done a poor job of using the computer to do their job. Engineering disciplines and methodologies are now emerging supported by software tools that address the problems of software development. This paper addresses some of the current software engineering methodologies as a backdrop for the general evaluation of computer assisted software engineering (CASE) tools from actual installation of and experimentation with some specific tools.

    1981-07-01

    Prospects for North American tidal power electrical generation are reviewed. Studies by the US Army Corps of Engineers of 90 possible generation schemes in Cobscook Bay, ME, indicated that maximum power generation rather than dependable capacity was the most economic method. Construction cost estimates for 15 MW bulb units in a single effect mode from basin to the sea are provided; five projects were considered ranging from 110-160 MW. Additional tidal power installations are examined for: Half-Moon Cove, ME (12 MW, 18 ft tide); Cook Inlet, AK, which is shown to pose severe environmental and engineering problems due to fish migration, earthquake hazards, and 300 ft deep silt deposits; and the Bay of Fundy, Canada. This last has a 17.8 MW plant under construction in a 29 ft maximum tide area. Other tidal projects of the Maritime Provinces are reviewed, and it is noted that previous economic evaluations based on an oil price of $16/barrel are in need of revision.

    2009-12-01

    A reconnaissance team was mobilized to American Samoa and Western Samoa in the days that followed the Mw 8.0 earthquake and destructive tsunami. The Geo-Engineering Extreme Events Reconnaissance (GEER) team was assembled to investigate the geotechnical effects of both the earthquake event and the tsunami effects on the coastal environment. The team also made observations on structural engineering and lifeline aspects, although these were not the primary focus. The GEER team employed a number of useful technologies to facilitate effective reconnaissance. Each team member utilized a common GPS unit and laptop with a Google Earth GIS database to track visited locations. The team also deployed with LIDAR equipment to map areas of tsunami devastation to include scour, erosion, and structural damage. The LIDAR scanning was performed in Pago Pago, Alao, Tula, Leone and Poloa on the island of Western Samoa. In Pago Pago, the scans map the location of several debris piles and damaged structures. In Alao, scour around a foundation was mapped using the TLS. The structure atop the foundation was completely destroyed. Finally, the scans also show the location of beach sediment that was washed up off of the beach. In Tula, scans were performed to show the damages to several buildings in the village. A scan was done adjacent to the beach to show some of the coastal erosion and damages and map sediment dislocation. In Leone, structural damage to buildings and bridges were mapped (see Figure). The scans also map scouring along a rock wall along the riverside and a substantial amount of erosion that occurred along one of the river banks. In the village of Poloa, scans show the location of the trim line, where the tsunami waves reached. Also, damages to structures, such as a school building, were recorded along with the location of fresh coral deposited on the beach, scour and erosion. The LIDAR data was important to the investigation for multiple reasons. First, it provided a quick

  9. Solar cycle modulation of the Pacific–North American teleconnection influence on North American winter climate

    International Nuclear Information System (INIS)

    We investigate the role of the 11-year solar cycle in modulating the Pacific–North American (PNA) influence on North American winter climate. The PNA appears to play an important conduit between solar forcing and surface climate. The low solar (LS) activity may induce an atmospheric circulation pattern that resembles the positive phase of the PNA, resulting in a significant warming over northwestern North America and significant dry conditions in the Pacific Northwest, Canadian Prairies and the Ohio-Tennessee-lower Mississippi River Valley. The solar-induced changes in surface climate share more than 67% and 14% of spatial variances in the PNA-induced temperature and precipitation changes for 1950–2010 and 1901–2010 periods, respectively. These distinct solar signatures in North American climate may contribute to deconvolving modern and past continental-scale climate changes and improve our ability to interpret paleoclimate records in the region.

    2004-01-01

    A method, and a computer program that helps to implement the method, have been developed to automate and systematize the retention and retrieval of all the written records generated during the process of designing a complex engineering system. It cannot be emphasized strongly enough that all the written records as used here is meant to be taken literally: it signifies not only final drawings and final engineering calculations but also such ancillary documents as minutes of meetings, memoranda, requests for design changes, approval and review documents, and reports of tests. One important purpose served by the method is to make the records readily available to all involved users via their computer workstations from one computer archive while eliminating the need for voluminous paper files stored in different places. Another important purpose served by the method is to facilitate the work of engineers who are charged with sustaining the system and were not involved in the original design decisions. The method helps the sustaining engineers to retrieve information that enables them to retrace the reasoning that led to the original design decisions, thereby helping them to understand the system better and to make informed engineering choices pertaining to maintenance and/or modifications of the system. The software used to implement the method is written in Microsoft Access. All of the documents pertaining to the design of a given system are stored in one relational database in such a manner that they can be related to each other via a single tracking number.

  19. Harmonic engine

    Energy Technology Data Exchange (ETDEWEB)

    Bennett, Charles L. (Livermore, CA)

    2009-10-20

    A high efficiency harmonic engine based on a resonantly reciprocating piston expander that extracts work from heat and pressurizes working fluid in a reciprocating piston compressor. The engine preferably includes harmonic oscillator valves capable of oscillating at a resonant frequency for controlling the flow of working fluid into and out of the expander, and also preferably includes a shunt line connecting an expansion chamber of the expander to a buffer chamber of the expander for minimizing pressure variations in the fluidic circuit of the engine. The engine is especially designed to operate with very high temperature input to the expander and very low temperature input to the compressor, to produce very high thermal conversion efficiency.

  5. On the Record: The Philosophy of Recording

    Directory of Open Access Journals (Sweden)

    Martin Newman

    2011-03-01

    Full Text Available At the Theoretical Archaeology Group (TAG conference in Durham in December 2009 I organised a session on the philosophy of recording, and the three articles presented here originated in that discussion. The aim of the session was to consider some fundamental questions about the recording that archaeologists undertake but which are often overlooked, and think about these in a theoretical way. These questions included: ◦Why do we choose to record the sites, monuments and artefacts that we do? Why do we select the units of information we choose to record about them? How have the things we record and the attributes recorded changed over time? ◦How can the adoption of a reflexive approach enable us to assess the recording choices we make and inform those that will be made in the future? ◦What do these recording choices tell us about archaeology and wider society over time? ◦Can something as intangible as a database record or a digital photograph be considered as an artefact and studied as material culture? ◦How are new technologies changing recording and adding to the material available for study, which will form the historic documents of the future? The first two of these questions are decisions that archaeologists have been making since the earliest origins of the discipline, often without a passing thought. It is not very often that we pause to analyse them at a theoretical level. As recording has developed we have been very good at categorizing, making inventories and constructing ontologies to describe the past around us, but less good about asking why we do so in the way we do.

  12. Harmonic engine

    Energy Technology Data Exchange (ETDEWEB)

    Bennett, Charles L.; Sewall, Noel; Boroa, Carl

    2014-08-19

    An engine based on a reciprocating piston engine that extracts work from pressurized working fluid. The engine includes a harmonic oscillator inlet valve capable of oscillating at a resonant frequency for controlling the flow of working fluid into of the engine. In particular, the inlet valve includes an inlet valve head and a spring arranged together as a harmonic oscillator so that the inlet valve head is moveable from an unbiased equilibrium position to a biased closed position occluding an inlet. Upon releasing the inlet valve the inlet valve head undergoes a single oscillation past the equilibrium positio to a maximum open position and returns to a biased return position close to the closed position to choke the flow and produce a pressure drop across the inlet valve causing the inlet valve to close. Protrusions carried either by the inlet valve head or piston head are used to bump open the inlet valve from the closed position and initiate the single oscillation of the inlet valve head, and protrusions carried either by the outlet valve head or piston head are used to close the outlet valve ahead of the bump opening of the inlet valve.

  13. Ultimate limits to thermally assisted magnetic recording

    International Nuclear Information System (INIS)

    The application of thermal energy to enable recording on extremely high anisotropy magnetic media appears to be a viable means of extending the density of stored information. The central physical issue facing the technology is what gain can be realized in writability along with long-term data stability using imaginable media materials. We reasonably expect the material properties M(T) and Hk(T) to determine this, since a stability metric for media with characteristic magnetization switching unit volume V is MV Hk/2kBT. This matter is controversial owing to still open questions related to thermomagnetic recording with temperature elevation above the Curie point and optimal cooling rates. There are indications that multi-component magnetic media may offer advantages in achieving performance goals. Beyond the physical issues lie engineering matters related to the correct system architecture to yield a practical storage device to meet future customer expectations. Here one must address a detailed means of delivering localized heating to the magnetic medium to perform efficient recording. To date, magnetic recording devices have been highly mechanical systems, so it is natural to inquire how a need for an aggressively heated head-medium interface could impact the evolution of future systems. Eventually elements of thermally assisted recording could be combined with patterned media approaches such as self-organized magnetic arrays to push toward ultimate limits where the thermal instability of bits overtakes engineered media materials. Finally, a practical recording system cannot be realized unless a means of finding, following, and reading the smallest bits with a usable signal-to-noise ratio exists-engineering issues separate from an ability to reliably record those bits.

    2004-01-01

    The Space Power and Propulsion Test Engineering Branch at NASA Glenn Research center has the important duty of controlling electronic test engineering services. These services include test planning and early assessment of Space projects, management and/or technical support required to safely and effectively prepare the article and facility for testing, operation of test facilities, and validation/delivery of data to customer. The Space Electronic Test Engineering Branch is assigned electronic test engineering responsibility for the GRC Space Simulation, Microgravity, Cryogenic, and Combustion Test Facilities. While working with the Space Power and Propulsion Test Engineering Branch I am working on several different assignments. My primary assignment deals with an electrical hardware unit known as Sunny Boy. Sunny Boy is a DC load Bank that is designed for solar arrays in which it is used to convert DC power form the solar arrays into AC power at 60 hertz to pump back into the electricity grid. However, there are some researchers who decided that they would like to use the Sunny Boy unit in a space simulation as a DC load bank for a space shuttle or even the International Space Station hardware. In order to do so I must create a communication link between a computer and the Sunny Boy unit so that I can preset a few of the limits (such power, set & constant voltage levels) that Sunny Boy will need to operate using the applied DC load. Apart from this assignment I am also working on a hi-tech circuit that I need to have built at a researcher s request. This is a high voltage analog to digital circuit that will be used to record data from space ion propulsion rocket booster tests. The problem that makes building this circuit so difficult is that it contains high voltage we must find a way to lower the voltage signal before the data is transferred into the computer to be read. The solution to this problem was to transport the signal using infrared light which will lower

    For the past decade, the Department of Energy (DOE) has sponsored projects to develop diesel and gas turbine engines capable of operating on low-cost, coal-based fuels. Much of the current work addresses the use of coal-water fuel (CWF) in diesel and turbines, although there is some work with dry coal feed and other coal fuels. Both the diesel and gas turbine portions of the program include proof-of-concept and support projects. Specific highlights of the program include: engine tests and economic analyses have shown that CWF can replace 70 percent of the diesel oil used in the duty cycle of a typical main-line locomotive; A. D. Little and Cooper-Bessemer completed a system and economic study of coal-fueled diesel engines for modular power and industrial cogeneration markets. The coal-fueled diesel was found to be competitive at fuel oil prices of $5.50 per million British thermal units (MBtu); Over 200 hours of testing have been completed using CWF in full-scale, single-cylinder diesel engines. Combustion efficiencies have exceeded 99 percent; Both CWF and dry coal fuel forms can be burned in short residence time in-line combustors and in off-base combustors with a combustion efficiency of over 99 percent; Rich/lean combustion systems employed by the three major DOE contractors have demonstrated low NO(sub x) emissions levels; Contractors have also achieved promising results for controlling sulfur oxide (SO(sub x)) emissions using calcium-based sorbents; Slagging combustors have achieved between 65 and 95 percent slag capture, which will limit particulate loading on pre-turbine cleanup devices. For many of the gas turbine and diesel applications emission standards do not exist. Our goal is to develop coal-fueled diesels and gas turbines that not only meet all applicable emission standards that do exist, but also are capable of meeting possible future standards.

    Engineering programs have been less successful than other professions in achieving gender equity. Analyses of gender differences in the attitudes and interests of engineering students may help illuminate ways to combat the underrepresentation of women in engineering. This study examined data collected from 863 engineering students who attended 15 American universities from fall 2005 through spring 2006 using an online survey. The survey was designed to understand the backgrounds, academic preparation, motivation, interests, and attitudes of engineering students. To determine whether males and females received different academic preparation prior to entering engineering, the survey examined participants' mathematics, science, and technical coursework taken in high school. The questions probed students' comfort and interest level in mathematics, science, and technology/engineering and investigated student interest in the three fundamental engineering activities by asking 49 design, build, and analyze questions on topics covering a variety of engineering disciplines. A combination of question formats was used including pre-categorized demographic information, 5-point Likert scales, and open-ended responses. Gender similarities and differences were identified and their implications were considered for the recruitment and retention of engineers. Female engineering students in this study were equally or better prepared than males to major in engineering based on the number and types of science and mathematics classes taken in high school. However, statistically significant gender differences were found in the attitudes and interests of engineering students. The difference in the comfort level, interest in learning, being able to demonstrate, or in performing stem skills depended on the question topic rather than gender. The areas with the highest comfort and interest level were often different for females and males. Several topics and curriculum areas of high interest to

    1999-10-01

    The application of biotechnology to the production of commodity products (fuels, chemicals, and materials) offering benefits in terms of sustainable resource supply and environmental quality is an emergent area of intellectual endeavor and industrial practice with great promise. Such "biocommodity engineering" is distinct from biotechnology motivated by health care at multiple levels, including economic driving forces, the importance of feedstocks and cost-motivated process engineering, and the scale of application. Plant biomass represents both the dominant foreseeable source of feedstocks for biotechnological processes as well as the only foreseeable sustainable source of organic fuels, chemicals, and materials. A variety of forms of biomass, notably many cellulosic feedstocks, are potentially available at a large scale and are cost-competitive with low-cost petroleum whether considered on a mass or energy basis, and in terms of price defined on a purchase or net basis for both current and projected mature technology, and on a transfer basis for mature technology. Thus the central, and we believe surmountable, impediment to more widespread application of biocommodity engineering is the general absence of low-cost processing technology. Technological and research challenges associated with converting plant biomass into commodity products are considered relative to overcoming the recalcitrance of cellulosic biomass (converting cellulosic biomass into reactive intermediates) and product diversification (converting reactive intermediates into useful products). Advances are needed in pretreatment technology to make cellulosic materials accessible to enzymatic hydrolysis, with increased attention to the fundamental chemistry operative in pretreatment processes likely to accelerate progress. Important biotechnological challenges related to the utilization of cellulosic biomass include developing cellulase enzymes and microorganisms to produce them, fermentation of

    Maria Lenk is widely recognized as an exceptional athlete who participated in women's sport from around 1930 until 1950. In 1932, at the age of seventeen, she was the first woman to be included in a Latin American delegation to the Olympic Games. As a swimmer, she still sets world records at the age of eighty-six. This super-champion's sporting achievements and her persistent dedication to the advancement of sport still impress and surprise todays professional swimmers and researchers. Contextualised in the male-dominated society of Brazil during the first half of the twentieth century, this chapter traces the achievement, and rise to international fame, of Maria Lenk. It examines the factors that enabled her to emerge not only as an important figure in sport but also as an icon of female emancipation in Brazilian and Latin American society. The focus is on Lenk's influence on the issues which affected the development of women's sport in Latin America. It also highlights the significance of Lenk's contribution to the changing place of women in Brazilian and South American society. PMID:18604909

    This volume presents the proceedings of the 15th ICMBE held from 4th to 7th December 2013, Singapore. Biomedical engineering is applied in most aspects of our healthcare ecosystem. From electronic health records to diagnostic tools to therapeutic, rehabilitative and regenerative treatments, the work of biomedical engineers is evident. Biomedical engineers work at the intersection of engineering, life sciences and healthcare. The engineers would use principles from applied science including mechanical, electrical, chemical and computer engineering together with physical sciences including physics, chemistry and mathematics to apply them to biology and medicine. Applying such concepts to the human body is very much the same concepts that go into building and programming a machine. The goal is to better understand, replace or fix a target system to ultimately improve the quality of healthcare. With this understanding, the conference proceedings offer a single platform for individuals and organisations working i...

  8. Key Future Engineering Capabilities for Human Capital Retention

    Sivich, Lorrie

    Projected record retirements of Baby Boomer generation engineers have been predicted to result in significant losses of mission-critical knowledge in space, national security, and future scientific ventures vital to high-technology corporations. No comprehensive review or analysis of engineering capabilities has been performed to identify threats related to the specific loss of mission-critical knowledge posed by the increasing retirement of tenured engineers. Archival data from a single diversified Fortune 500 aerospace manufacturing engineering company's engineering career database were analyzed to ascertain whether relationships linking future engineering capabilities, engineering disciplines, and years of engineering experience could be identified to define critical knowledge transfer models. Chi square, logistic, and linear regression analyses were used to map patterns of discipline-specific, mission-critical knowledge using archival data of engineers' perceptions of engineering capabilities, key developmental experiences, and knowledge learned from their engineering careers. The results from the study were used to document key engineering future capabilities. The results were then used to develop a proposed human capital retention plan to address specific key knowledge gaps of younger engineers as veteran engineers retire. The potential for social change from this study involves informing leaders of aerospace engineering corporations on how to build better quality mentoring or succession plans to fill the void of lost knowledge from retiring engineers. This plan can secure mission-critical knowledge for younger engineers for current and future product development and increased global competitiveness in the technology market.

    In July 2005 the North American Solar Challenge (NASC) featured university built solar powered cars ran across the United States into Canada. The competition began in Austin, Texas with stops in Weatherford, Texas; Broken Arrow, Oklahoma; Topeka, Kansas; Omaha, Nebraska; Sioux Falls, South Dakota, Fargo, North Dakota; Winnipeg, Manitoba; Brandon, Manitoba; Regina, Saskatchewan; Medicine Hat, Alberta; mainly following U.S. Highway 75 and Canadian Highway 1 to the finish line in Calgary, Alberta, Canada, for a total distance of 2,500 miles. NASC major sponsors include the U.S. Department of Energy (DOE), Natural Resources Canada and DOEs National Renewable Energy Laboratory. The event is designed to inspire young people to pursue careers in science and engineering. NASCs predecessors, the American Solar Challenge and Sunrayce, generally have been held every two years since 1990. With each race, the solar cars travel faster and further with greater reliability. The NASC promotes: -Renewable energy technologies (specifically photovoltaic or solar cells) -Educational excellence in science, engineering and mathematics -Creative integration of technical and scientific expertise across a wide-range of disciplines -Hands-on experience for students and engineers to develop and demonstrate their technical and creative abilities. Safety is the first priority for the NASC. Each team put its car through grueling qualifying and technical inspections. Teams that failed to meet the requirements were not allowed participate. During the race, each team was escorted by lead and chase vehicles sporting rooftop hazard flashers. An official observer accompanied each solar car team to keep it alert to any safety issues.

    and also safely shutdown the engines. The test will last for a period of 8000 to 9000 hours. Other types of tests that have been performed are: performance mapping, controller development, launch environment, and vibration emissions testing. Currently, the thermo-mechanical system branch is housing a RG-350, a stirling convertor. The convertor was used in previous tests such as a Hall Thruster test, world s first integrated test of a dynamic power system with electric propulsion. Another test performed was to conclude if free piston stirling convertors can be synchronized for vibration balancing, with no thermodynamic or electrical connections and not cause both to shutdown if one failed. The ability to reduce vibration by synchronizing convertor operation but still be able to operate when one partner fails is pertinent in space and terrestrial applications. The convertor is now being brought back into operation and a controller is in the process of being developed. This convertor will be used as a testbed for new controllers. I worked with Mary Ellen Roth on the electric engineering aspects of the RG-350. My main goal was to enhance the data collection process. I worked on different aspects of the RG-350, with a main focus on the engine controller. I drew a schematic of the wire connections in the engine controller, using PCB Express, so that a plan could be devised to connect the power meter properly between the output of the engine and the engine controller. I measured the power using two different instruments: Valhalla Scientific power meter and Ohio Semitronics power measurement device. The convertor is connected to an Agilent 34970A Data Acquisition/Switch Unit, which allows the user to measure, record, and monitor voltage, current, frequency, and temperature. I assisted in preparing the Data Acquisition for general operation. I also helped test a panel of transducers, which will be placed in the rack that powers and monitors the convertor.

    On the basis of the connectionist model of leadership, we examined perceptions of leadership as a function of the contextual factors of race (Asian American, Caucasian American) and occupation (engineering, sales) in 3 experiments (1 student sample and 2 industry samples). Race and occupation exhibited differential effects for within- and between-race comparisons. With regard to within-race comparisons, leadership perceptions of Asian Americans were higher when race-occupation was a good fit (engineer position) than when race-occupation was a poor fit (sales position) for the two industry samples. With regard to between-race comparisons, leadership perceptions of Asian Americans were low relative to those of Caucasian Americans. Additionally, when race-occupation was a good fit for Asian Americans, such individuals were evaluated higher on perceptions of technical competence than were Caucasian Americans, whereas they were evaluated lower when race-occupation was a poor fit. Furthermore, our results demonstrated that race affects leadership perceptions through the activation of prototypic leadership attributes (i.e., implicit leadership theories). Implications for the findings are discussed in terms of the connectionist model of leadership and leadership opportunities for Asian Americans. PMID:20718523

    The reliable and valid assessment of chronic worry in African Americans is vital when attempting to draw cross-cultural comparisons between African Americans and other ethnic groups. As such, the current study examined the psychometric properties of a brief version of a gold standard assessment of chronic worry, specifically the Penn State Worry Questionnaire-Abbreviated (PSWQ-A; Hopko et al., 2003) in a college sample of African Americans (n = 100) and European Americans (n = 121). Results indicated that the PSWQ-A total score has good internal consistency and convergent validity with another measure of anxiety, but less than favorable discriminant validity with a measure of depression in African American and European American students. Also, the 1-factor solution for the 8-item PSWQ-A had excellent model fit in our full sample and was partially invariant between ethnic groups. Collectively, the present study provides evidence that the PSWQ-A is a psychometrically sound option for assessing chronic worry and suggests that this brief measure may enhance the time efficiency and clinical utility of research and clinical assessments in ethnically diverse samples.

    Honda Motor Company of Japan in a four-year period from 1968 to 1872 designed, tested, and mass-produced a stratified charge engine, the CVCC, which in comparison to conventional engines of similar output at the time was lower in CO, HC and NO/sub x/ emissions and higher in fuel economy. Honda developed the CVCC engine without government assistance or outside help. Honda's success came at a time when steadily increasing fuel costs and the various provisions of the Clean Air Act had forced US automakers to consider possible alternatives to the conventional gasoline engine. While most major engine manufacturers had investigated some form of stratified charge engine, Honda's CVCC was the only one to find successful market application. This case study examines the circumstances surrounding the development of the CVCC engine and its introduction into the Japanese and American markets.

    South America still has enormous potential for the further development of hydroelectric power. The reasons why much of the potential remains untapped are discussed and here environmental considerations are prominent: to a lesser extent, war, military coups, corruption, bad management and hyperinflation have all contributed. Some examples of disastrous South American hydro projects are given. Argentina sees a possible solution in using international contractors. However, privatisation has produced some success stories, notably the Canon del Plato hydro plant in Peru and the Duqueco project in Chile. (UK)

    Astekar, Madhusudan; Saawarn, Swati; Ramesh, Gayathri; Saawarn, Nisheeth

    2011-01-01

    Context: Dental remains are usually the last to get destroyed among body parts after death. They may be useful for personal identification in cases of mass disasters and decomposed unidentified bodies. Dental records may help in the identification of suspects in criminal investigations and in medicolegal cases. Maintenance of dental records is legally mandatory in most of the European and American countries. Unfortunately, the law is not very clear in India, and the awareness is very poor. Aims: To assess the awareness regarding the dental record maintenance among dentists in Rajasthan, to deduce the quality of average dental records kept by them and to evaluate the potential use of their maintained records, in any of forensic or medicolegal cases. Settings and Design: A cross-sectional survey was conducted among 100 dental practitioners of different cities in Rajasthan, India. Materials and Methods: Data were collected through a structured questionnaire, which was responded by the study population in the course of a telephonic interview. The questionnaire addressed on the mode of maintaining dental records in their regular practice. Statistical Analysis Used: The data so gathered were subjected for descriptive analysis. Results: As for knowledge or awareness about maintaining dental records, surprisingly a very low percentile (about 38%) of surveyed dentists maintained records. Sixty-two percent of the dentists were maintaining no records at all. Conclusion: Nonmaintenance or poor quality of records maintained indicates that the dentists in Rajasthan are not prepared for any kind of forensic and medicolegal need if it arises. PMID:22408320

    1981-01-01

    An intake valve arrangement for positively controlling the opening and closing of the poppet valve in a hot gas cylinder in a hydrazine powered engine is described. The poppet valve is operated by the piston and gas pressure only. The poppet valve uses a pneumatic spring which holds the poppet valve against the piston while the valve is opened and closed. To accomplish this, a poppet valve is slidably mounted in a pneumatic spring chamber which reaches a pressure approaching the gas supply pressure and, during the opening of the valve, the spring chamber retains enough pressure to hold the poppet valve onto the piston. In addition, the bottom of the poppet valve can have a suction cup type configuration to hold the poppet valve on the piston during the down stroke.

    Thomas, David T; Hartnett, James P; Hughes, William F

    1973-01-01

    The applications involving electromagnetic fields are so pervasive that it is difficult to estimate their contribution to the industrial output: generation of electricity, power transmission lines, electric motors, actuators, relays, radio, TV and microwave transmission and reception, magnetic storage, and even the mundane little magnet used to hold a paper note on the refrigerator are all electromagnetic in nature. One would be hard pressed to find a device that works without relaying on any electromagnetic principle or effect. This text provides a good theoretical understanding of the electromagnetic field equations but also treats a large number of applications. In fact, no topic is presented unless it is directly applicable to engineering design or unless it is needed for the understanding of another topic. In electrostatics, for example, the text includes discussions of photocopying, ink-jet printing, electrostatic separation and deposition, sandpaper production, paint spraying, and powder coating.

  5. Reactor safety engineering

    International Nuclear Information System (INIS)

    The concept of the work is such that the basic safety philosophy for nuclear power plants as well as the safety features of both types of light water reactors, pressurized and boiling water reactors, and of the fast breeder reactor are dealt with. With the pressurized and boiling water reactors also variations, due to different supplies are mentioned. The state of development considered is characterized by the results of the American reactor safety study having very much influenced the way of presentation and the validity of the information contained. In the introduction the attentive reader is made familiar with the basic traits of safety engineering, the traditional deterministic way of proceeding being supplemented by a detailed illustration of probabilistic means used in the safety analysis. Added to this are comparative descriptions of the individual safety features, their design and mode of operation. There are, e.g., detailed discussion of the emergency core cooling systems, the power supply systems, the reactor protection system, and the containment. Special chapters are attributed to transients with and without the fast shutdown system working and to loss of coolant. The so-called external events are treated somewhat shortly whereas much space is given to core melting problems. The treatment of important events from the safety point of view, including the section on Harrisburg added for reasons of immediate interest, is limited to phenomenological description. (orig.)

  6. Special requirements of electronic health record systems in pediatrics.

    Spooner, S Andrew

    2007-03-01

    Some functions of an electronic health record system are much more important in providing pediatric care than in adult care. Pediatricians commonly complain about the absence of these "pediatric functions" when they are not available in electronic health record systems. To stimulate electronic health record system vendors to recognize and incorporate pediatric functionality into pediatric electronic health record systems, this clinical report reviews the major functions of importance to child health care providers. Also reviewed are important but less critical functions, any of which might be of major importance in a particular clinical context. The major areas described here are immunization management, growth tracking, medication dosing, data norms, and privacy in special pediatric populations. The American Academy of Pediatrics believes that if the functions described in this document are supported in all electronic health record systems, these systems will be more useful for patients of all ages.

  7. Recording-based identification of site liquefaction

    Reconnaissance reports and pertinent research on seismic hazards show that liquefaction is one of the key sources of damage to geotechnical and structural engineering systems. Therefore, identifying site liquefaction conditions plays an important role in seismic hazard mitigation. One of the widely used approaches for detecting liquefaction is based on the time-frequency analysis of ground motion recordings, in which short-time Fourier transform is typically used. It is known that recordings at a site with liquefaction are the result of nonlinear responses of seismic waves propagating in the liquefied layers underneath the site. Moreover, Fourier transform is not effective in characterizing such dynamic features as time-dependent frequency of the recordings rooted in nonlinear responses. Therefore, the aforementioned approach may not be intrinsically effective in detecting liquefaction. An alternative to the Fourier-based approach is presented in this study,which proposes time-frequency analysis of earthquake ground motion recordings with the aid of the Hilbert-Huang transform (HHT), and offers justification for the HHT in addressing the liquefaction features shown in the recordings. The paper then defines the predominant instantaneous frequency (PIF) and introduces the PIF-related motion features to identify liquefaction conditions at a given site. Analysis of 29 recorded data sets at different site conditions shows that the proposed approach is effective in detecting site liquefaction in comparison with other methods.

  8. Disturbance recording system

    International Nuclear Information System (INIS)

    A computerized system for disturbance monitoring, recording and display has been developed for use in nuclear power plants and is versatile enough to be used where ever a large number of parameters need to be recorded, e.g. conventional power plants, chemical industry etc. The Disturbance Recording System (DRS) has been designed to continuously monitor a process plant and record crucial parameters. The DRS provides a centralized facility to monitor and continuously record 64 process parameters scanned every 1 sec for 5 days. The system also provides facility for storage of 64 parameters scanned every 200 msec during 2 minutes prior to and 3 minutes after a disturbance. In addition the system can initiate, on demand, the recording of 8 parameters at a fast rate of every 5 msec for a period of 5 sec. and thus act as a visicorder. All this data is recorded in non-volatile memory and can be displayed, printed/plotted and used for subsequent analysis. Since data can be stored densely on floppy disks, the volume of space required for archival storage is also low. As a disturbance recorder, the DRS allows the operator to view the state of the plant prior to occurrence of the disturbance and helps in identifying the root cause. (author). 10 refs., 7 figs

  18. Emplacement engineering

    International Nuclear Information System (INIS)

    Emplacement Engineering can be defined as that portion of a nuclear explosive project that is concerned with the emplacement of the explosive. This definition would then include virtually everything except the design and fabrication of the explosive and the post-shot-effects program. For future commercial application, the post-shot-effects program will essentially disappear. This emplacement portion of a nuclear explosive project constitutes a large fraction of the total project cost, but it has largely been overshadowed by the explosive and explosive-effects portions. As we move into commercial applications. Emplacement Engineering must receive more attention from both industry and government. To place emplacement costs in their proper relationship with total projects costs, we have performed a study of commercial underground nuclear explosive applications such as gas stimulation. Although there are many intangibles in such a study, we have been able to at least obtain some feel for the relative fractional costs of the non-explosive costs compared with the explosive costs. This study involved estimating the cost elements for applications using a single explosive at 5,000 ft, 10,000 ft, and 15,000 ft. For each depth, the cost estimates were made for a range of emplacement hole and explosive diameters. Results of these estimates for explosive-related costs, hole-related costs, and total costs are shown for the three depths. Note that the explosive package outside diameter is assumed as 2 inches less than the hole (or casing) inside diameter for all cases. For the 5,000-ft application the explosive-related costs dominate, and of particular importance is the indicated diameter for minimum total cost which occurs at approximately a 17.5-in. hole (15.5-in. explosive). The hole-related costs are in 'the same range as the explosive-related costs for the 10,000-ft application. For this case, the minimum total cost occurs at approximately a 14-in. hole (12-in. explosive

    2014-11-01

    Full Text Available This research investigates how eight undergraduate African American women in science, math, and engineering (SME majors accessed cultural capital and informal science learning opportunities from preschool to college. It uses the multiple case study methodological approach and cultural capital as the framework to better understand their opportunities to engage in free-choice science learning. The article demonstrates that African American women have access to cultural capital and informal science learning inside and outside of home and school environments in P-16 settings. In primary and secondary schools, African American girls acquire cultural capital and access to free-choice science learning in the home environment, museums, science fairs, student organizations and clubs. However, in high school African American female teenagers have fewer informal science learning opportunities like those such as those provided in primary school settings. In college, cultural capital is transmitted through informal science learning that consisted of involvement in student organizations, research projects, seminars, and conferences. These experiences contributed to their engagement and persistence in SME fields in K-16 settings. This research adds to cultural capital and informal science learning research by allowing scholars to better understand how African American women have opportunities to learn about the hidden curriculum of science through informal science settings throughout the educational pipeline.
