    2015-08-01

    Full Text Available In his fascinat ing book "A Short History of the Future," published in 1992, W. Warren Wagar lays out a futuristic vision of the world over the next two hundred years that draws extensively on Inunanuel Wallerstein' s world-system theory. In the year 2001 began the last of the great Kondratieff upswings of the capitalist world-economy. That economy had come to be increasingly dominated by a few giant corporations, so that by 2015 12 "megacorps" had assumed control of the world-economy and thegovernments of the major capitalist powers. The Kondratieff upswing ran its course by the early 2030s and then a devastating worldwide depression set in, the lowest point of which was reached in 2043.

    X-ray or neutron diffraction experiment can provide microstructural information of crystalline materials. At the moment without the model of micro-structure, Warren-Averbach analysis is regarded as an important tool. For this purpose, a program of Warren-Averbach analysis has been developed. The pro- gram has nearly all basic functions, it can be conveniently used through a graphic user interface as well. In the end, the efficiency of the program is illustrated by an example of ceria.

  6. Warren Hunt to test granite well

    International Nuclear Information System (INIS)

    Harvie, W.

    1996-01-01

    Various theories which purport to explain the existence of the Alberta oil sands, were discussed briefly. One theory, held among others by Warren Hunt, speculates that oil is formed deep in the Precambrian basement and not in the higher sedimentary rock. According to this theory, methane in the crust is the abiogenic product that results from hydrogen reacting with silicon carbide in the lower mantle. As it rises through the fractures, it encounters the microbiota, and hydrogen is stripped away making larger molecules until only bitumen remains. Hunt and other adherents of this theory believe that hydrocarbon reservoirs are replenished as oil is produced, hence there is no end to the world's oil supply. This theory is about to be tested by retesting a granite well near Fort McMurray, which was suspended in September 1994, when funding dried up. Kaleeda Enterprises, owners of the well, believe that the well bottom is currently in a granite pool, and oil will be found by deepening the well to 2,150 metres from the current 1,650 metres. While this is not universally accepted, if true, the abiogenic theory would go a long way towards explaining the origin of the oil sands

    1998-01-01

    Various parameters for a nickel SPND viz. neutron and gamma sensitivity, their dependence on detector dimensions, effect of activity build up during irradiation in the reactor on neutron sensitivity and burn up have been calculated using an analytical model by Warren and Shah. The results show that the main component of neutron sensitivity is due to neutron-induced capture gamma rays (99.93%). Delayed β signal is negligible and signal due to external gamma rays constitute about 0.06%. Low gamma sensitivity to external gamma rays, negligible activity buildup and low burn up rate make it a very promising prompt SPND for power reactors. (orig.)

  9. Perturbed GUE Minor Process and Warren's Process with Drifts

    2014-01-01

    We consider the minor process of (Hermitian) matrix diffusions with constant diagonal drifts. At any given time, this process is determinantal and we provide an explicit expression for its correlation kernel. This is a measure on the Gelfand-Tsetlin pattern that also appears in a generalization of Warren's process (Electron. J. Probab. 12:573-590, 2007), in which Brownian motions have level-dependent drifts. Finally, we show that this process arises in a diffusion scaling limit from an interacting particle system in the anisotropic KPZ class in 2+1 dimensions introduced in Borodin and Ferrari (Commun. Math. Phys., 2008). Our results generalize the known results for the zero drift situation.

  10. History of geriatric medicine: from Hippocrates to Marjory Warren.

    Science.gov (United States)

    Ritch, A

    2012-01-01

    It is widely assumed that geriatric medicine was an invention of the twentieth century. However, from the time of Hippocrates, there has been interest in the prolongation of the lifespan, the maintenance of health in old age and agerelated disease patterns. The debate about whether old age was a natural phenomenon or a disease state was not resolved until the nineteenth century. Calls for medicine relating to old age to be recognised as a discrete entity at the time when medical specialisation was developing were disregarded until the second half of the twentieth century. This review discusses the history of the theories of ageing and of disease and the practice of medicine for older people from the classical period up to Marjory Warren's initiative in London in 1935 and the development of geriatrics as a medical specialty.

  13. Warren, McCain, and Obama Needed Fuzzy Sets at Presidential Forum

    2012-01-01

    Full Text Available During a presidential forum in the 2008 US presidential campaign, the moderator, Pastor Rick Warren, wanted Senator John McCain and then-Senator Barack Obama to define rich with a specific number. Warren wanted to know at what specific income level a person goes from being not rich to rich. The problem with this question is that there is no specific income at which a person makes the leap from being not rich to being rich. This is because rich is a fuzzy set, not a crisp set, with different incomes having different degrees of membership in the rich fuzzy set. Fuzzy logic is needed to properly ask and answer Warren's question about quantitatively defining rich. An imprecise natural language word like rich should be considered to have qualitative definitions, crisp quantitative definitions, and fuzzy quantitative definitions.

    The current research explores the prevalence of bullying behaviour at HMYOI Warren Hill and the Carlford Unit. The introduction of the no-smoking policy at the establishment was also explored in relation to its effect on bullying behaviour given that tobacco has historically been the main item that young people have been bullied for. The Direct and Indirect Prisoner behaviour Checklist--Revised (DIPC-R) and a questionnaire designed to identify the effect of the introduction of the no-smoking policy on bullying behaviour were used within this study to answer the following questions: what is the prevalence of bullying behaviour at Warren Hill and the Carlford Unit, and do young people at Warren Hill and the Carlford Unit think that the rate and nature of bullying has been affected by the introduction of the no-smoking policy? One hundred and fifteen young people took part in the study. At Warren Hill, Bully/Victims were the most prevalent type identified and this was significantly greater than the number of young people identified as Pure Victims or Not Involved. On the Carlford Unit, Not Involved was the most prevalent type identified, and this finding provides limited support for the theories of bullying behaviour identified within the present study. The study found that the rate of bullying decreased following the introduction of the no-smoking policy at Warren Hill. The findings from this study are being used in the development of a new Violence Reduction Policy at HMYOI Warren Hill.

    Robert, Jeanne A; Lindgren, B Staffan

    2010-04-01

    Surveys were conducted on regenerating stands of lodgepole pine to determine the relationship between root deformation and susceptibility to attack by the Warren root collar weevil, Hylobius warreni Wood. The total number of trees attacked by H. warreni did not differ between planted and natural trees. A matched case-control logistic regression suggested that root cross-sectional area was more important in predicting weevil attack for naturally regenerated trees than for planted trees, but weevils were associated with a larger reduction in height-to-diameter ratios for trees with planted root characteristics than for trees with natural root form. Neither the stability of attacked versus unattacked trees differed significantly and there was no significant interaction of weevil attack and tree type, but weevil-killed trees had different root characteristics than alive, attacked trees. Lateral distribution and root cross-sectional area were significant predictors of alive attacked trees versus weevil-killed trees, suggesting that trees with poor lateral spread or poor root cross-sectional area are more likely to die from weevil attack. We conclude that root deformation does not necessarily increase susceptibility to attack but may increase the likelihood of mortality. Thus, measures to facilitate good root form are needed when planting pine in areas with high risk of Warren root collar weevil attack.

    1986-06-01

    Computed tomography with contrast injection was carried out in 18 patients who had undergone a Warren procedure for portal hypertension due to cirrhosis of the liver more than five years previously. The results show that it is not possible to drain only a part of the venous portal territory. The portal circulation does not consist of two portions, with different pressure relationships. Pressure difference across the splenorenal anastomosis is greater than that into the mediastinal veins. Postoperative development of a hepatofugal circulation continues for a long period and is not confined to the early phase only. This phenomenon is, however, not uniform. In particular, there are variations in the extent of the collateral circulation and in the maintenance of liver blood flow.

    The proposed Penelec project is one of 5 projects for potential funding under the fifth solicitation under the Clean Coal Technology program. In Penelec, two existing boilers would be replaced at Warren Station, PA; the new unit would produce 73 MW(e) in a combined cycle mode (using both gas-fired and steam turbines). The project would fill the need for a full utility-size demonstration of externally fire combined cycle (EFCC) technology as the next step toward commercialization. This environmental assessment was prepared for compliance with NEPA; its purpose is to provide sufficient basis for determining whether to prepare an environmental impact statement or to issue a finding of no significant impact. It is divided into the sections: purpose and need for proposed action; alternatives; brief description of affected environment; environmental consequences, including discussion of commercial operation beyond the demonstration period.

  9. Applications of the Warren-Averbach method of X-ray diffraction line profile analysis

    2013-01-01

    The objective of this work was to develop and implement a methodology of X-ray Line Profile Analysis (XLPA) for the study and determination of the mean crystallite sizes and microstrains in materials. A computer program was developed to speed up the treatment of diffraction peaks and perform the deconvolution utilizing the Stokes method to correct the instrumental contribution in the X-ray diffraction measurements. The XLPA methods used were the Scherrer, Williamson-Hall and Single-Line methods, which can be called real space methods, and the Fourier space method of Warren-Averbach. Furthermore, considering a mathematical modelling it was possible to calculate the crystallite size distribution, considering the log-normal distribution and spherical crystallites. It was possible to demonstrate the proposed theory can provide reliable results evaluating a dispersion parameter. The methodologies described above were applied in two distinct materials: in the alloy Zircaloy-4 and in ZnO. (author)

  10. Demonstration of Security Benefits of Renewable Generation at FE Warren Air Force Base

    Warwick, William M.; Myers, Kurt; Seifert, Gary

    2010-01-01

    Report detailing field demonstration of security benefits of renewable generation at FE Warren Air Force Base. The 2006 National Defense Appropriations Act directed the Department of Defense (DOD) to coordinate the testing of a wind turbine (new to the U.S. market) at an Air Force installation as a follow on to analyses conducted by the Pacific Northwest National Laborabory (PNNL) as part of the 2005 DOD Renewable Assessment. The earlier study simulated the performance of renewable power produced from wind turbines, solar photovoltaics and geothermal energy as part of a Base-wide energy security solution. The simulation concluded that integration of renewable generating resources with emergency generators, typically diesel-fired, could significantly enhance energy security and extend power supplies during prolonged commercial grid power outages. A simulation is insufficient to convince skeptics of the reliability of renewable resources, especially those that produce power only intermittently, like wind and solar. Therefore, Congress requested a field demonstration be performed using a wind turbine because wind power is the most erratic of all renewable resources. Following this direction, the Air Force identified a site for the wind turbine demonstration and contracted with the Idaho National Laboratory (INL) and PNNL to conduct the demonstration and implement other provisions in the appropriation bill. INL identified a wind turbine that met the legislative requirements (the Gamesa G-80), and with the support of PNNL and the Air Force, selected FE Warren Air Force Base for the demonstration. FE Warren has an excellent wind resource and was already a host to two wind turbines and could accommodate a third. The G-80 is rated at 2 MWs versus the two existing 660 kW turbines, consequently wind production would more than double. Procurement, siting, and acceptance testing of the new turbine was completed in early 2010. The field test was conducted in late April 2010

    In the calculational model developed by Warren and Shah for the computation of the gamma sensitivity ( Sγ) it has been observed that the computed Sγ value is quite sensitive to the space charge distribution function assumed for the insulator region and the energy of the gamma photons. The Sγ of SPNDs with Pt, Co and V emitters (manufactured by Thermocoax, France) has been measured at 60Co photon energy and a good correlation between the measured and computed values has been obtained using a composite space charge density function (CSCD), the details of which are presented in this paper. The arguments are extended for evaluating the Sγ values of several SPNDs for which Warren and Shah reported the measured values for a prompt fission gamma spectrum obtained in a swimming pool reactor. These results are also discussed.

    Technician Shawn Warren carefully smoothes out the composite skin of an instrument fairing atop the upper fuselage of the Altair unmanned aerial vehicle (UAV) at General Atomics Aeronautical Systems, Inc., facility at Adelanto, Calif. General Atomics Aeronautical Systems, Inc., is developing the Altair version of its Predator B unmanned reconnaissance aircraft under NASA's Environmental Research Aircraft and Sensor Technology (ERAST) project. NASA plans to use the Altair as a technology demonstrator to validate a variety of command and control technologies for UAVs, as well as demonstrate the capability to perform a variety of Earth science missions. The Altair is designed to carry an 700-lb. payload of scientific instruments and imaging equipment for as long as 32 hours at up to 52,000 feet altitude. Eleven-foot extensions have been added to each wing, giving the Altair an overall wingspan of 86 feet with an aspect ratio of 23. It is powered by a 700-hp. rear-mounted TPE-331-10 turboprop engine, driving a three-blade propeller. Altair is scheduled to begin flight tests in the fourth quarter of 2002, and be acquired by NASA following successful completion of basic airworthiness tests in early 2003 for evaluation of over-the-horizon control, detect, see and avoid and other technologies required to allow UAVs to operate safely with other aircraft in the national airspace.

  13. Size distribution of magnetic iron oxide nanoparticles using Warren-Averbach XRD analysis

    2012-07-01

    We use the Fourier transform based Warren-Averbach (WA) analysis to separate the contributions of X-ray diffraction (XRD) profile broadening due to crystallite size and microstrain for magnetic iron oxide nanoparticles. The profile shape of the column length distribution, obtained from WA analysis, is used to analyze the shape of the magnetic iron oxide nanoparticles. From the column length distribution, the crystallite size and its distribution are estimated for these nanoparticles which are compared with size distribution obtained from dynamic light scattering measurements. The crystallite size and size distribution of crystallites obtained from WA analysis are explained based on the experimental parameters employed in preparation of these magnetic iron oxide nanoparticles. The variation of volume weighted diameter (Dv, from WA analysis) with saturation magnetization (Ms) fits well to a core shell model wherein it is known that Ms=Mbulk(1-6g/Dv) with Mbulk as bulk magnetization of iron oxide and g as magnetic shell disorder thickness.

  14. In Appreciation of Claude Warren and Susan Rose's "William Pengelly's Techniques of Archaeological Excavation"

    Directory of Open Access Journals (Sweden)

    David L. Browman

    1997-11-01

    Full Text Available The short (40 pages pamphlet by Warren and Rose (1994 provides the answer to a complex question regarding credit for an important archaeological methodology, stratigraphic excavation. Let me set the stage for this appreciation. Continuing research on the beginnings of stratigraphic excavations in North America (Browman and Givens 1996, I sought the origins of the idea of actually excavating by strata, rather than post-facto interpretation, seen in North American as early as 1895 in the work of Henry Chapman Mercer, but not really introduced into the repertoire of American techniques until the work of Gamio, Kidder and Nelson between 1911 and 1914. The roots of the latter three seemed to lie with individuals such as Reisner, Boas, Uhle, who in turn seemed to rely on Hugo Obennaier, Gabriel de Mortillet, Marcellin Boule, and perhaps Pitt-Rivers, while Mercer's work could be traced to Boule and Albert Gaudry. Doggedly following back the roots, I found that Chapman (1989 could make a reasonable case that Pitt-Rivers had actually learned of the idea of strati­graphic excavation from Evans, Prestwich, and Lubbock, from the British scientists working with the Upper and Middle Paleolithic excavations during 1858-1868.

    Full Text Available Introduction. Extra-hepatic portal vein obstruction (EHPVO is one of the most often causes of portal hypertension in children. Objective. Establishing the importance of shunt surgery in combination with partial spleen resection in selected pediatric patients with EHPVO, enormous splenomegaly and severe hypersplenism. Methods. Distal splenorenal shunt (DSRS with partial spleen resection was performed in 22 children age from 2 to 17 years with EHPVO. Indications for surgery were pain and abdominal discomfort caused by spleen enlargement, as well as symptomatic hypersplenism with leucopenia, thrombocytopenia and anemia. The partial spleen resection was performed by ligation of blood vessels to caudal two thirds of the spleen. After ischemic parenchymal demarcation transection with electrocautery LigaSure was performed with preservation of 20-30% of spleen tissue, and then Warren DSRS was created. Platelet and leucocytes counts and liver function tests were obtained before, one month and one year after surgery. Growth was assessed with SD scores (Z scores for height, weight and body mass index at the time of surgery and one year later. Results. In all patients postoperative period was without significant complications. Platelets and leucocytes counts were normalized. Patency rate of shunts was 100%. Two significant shunts stenosis were observed and successfully treated with percutaneous angioplasty. During the follow-up period (1 to 9 years all patients were asymptomatic, with improved quality of life and growth. Conclusion. Results of our study indicate that shunt surgery with a partial spleen resection is an effective and safe procedure for patients with enormous splenomegaly and severe hypersplenism caused by EHPVO.

    Full Text Available World integration under a single state is foreseen by world -system theorists as the only means to save the world from destruction and chaos. The exhaustion of capitalism will lead, in their view, to the substitution of the current system of competing sovereign states by a democratic,liberal and socialist commonwealth. In his article Warren Wagar discusses who will lead this transition, and indirectly suggests that a world system party similar to that of his novel A Short History of the Future (1992 may be the most feasible way to guarantee the socialist character of the new world state.

    At the request of the Office of Independent Technical Review for the U.S. Department of Energy (DOE), Uranium Mill Tailings Remedial Action (UMTRA) Project, an independent technical review (peer review) was conducted during the period of September 15-17, 1992. The review was conducted by C. Warren Ankerberg (Geraghty ampersand Miller, Inc., Tampa, Florida) and Don Messinger (Roy F. Weston, Inc., West Chester, Pennsylvania). The peer review included a review of written documentation [water sampling standard operating procedures (SOP)], an inspection of technical reports and other deliverables, a review of staff qualifications and training, and a field visit to evaluate the compliance of field procedures with SOPs. The approach of the peer reviewers was to verify that the program meets the following criteria: Reported results are traceable to and consistent with recorded data. The basic assumptions and acceptance criteria are valid. Data are traceable to their origin and to reported analytical results. The procedures employed are consistent both internally and externally with written SOPs and regulatory guidelines. Inferences and conclusions are soundly based. The procedures and/or reports generated present work that satisfies the local, state and/or Federal regulatory requirements as applicable. The approach is consistent with industry standards and/or state-of-the-art technology, as practical. The data generated by activities are legally defensible and technically sound. UMTRA staff are adequately trained and qualified for the work. This document is a response to the observations, comments, and recommendations submitted by C. Warren Ankerberg following his review. The format of this document is to present the findings and recommendations verbatim from Mr. Ankerberg's report, followed by responses from the UMTRA Project staff. Included in the responses from the UMTRA Project staff are recommended changes in SOPs and strategies for implementing the changes

  7. XRD measurement of mean thickness, thickness distribution and strain for illite and illite-smectite crystallites by the Bertaut-Warren-Averbach technique

    1998-01-01

    A modified version of the Bertaut-Warren-Averbach (BWA) technique (Bertaut 1949, 1950; Warren and Averbach 1950) has been developed to measure coherent scattering domain (CSD) sizes and strains in minerals by analysis of X-ray diffraction (XRD) data. This method is used to measure CSD thickness distributions for calculated and experimental XRD patterns of illites and illite-smectites (I-S). The method almost exactly recovers CSD thickness distributions for calculated illite XRD patterns. Natural I-S samples contain swelling layers that lead to nonperiodic structures in the c* direction and to XRD peaks that are broadened and made asymmetric by mixed layering. Therefore, these peaks cannot be analyzed by the BWA method. These difficulties are overcome by K-saturation and heating prior to X-ray analysis in order to form 10-Å periodic structures. BWA analysis yields the thickness distribution of mixed-layer crystals (coherently diffracting stacks of fundamental illite particles). For most I-S samples, CSD thickness distributions can be approximated by lognormal functions. Mixed-layer crystal mean thickness and expandability then can be used to calculate fundamental illite particle mean thickness. Analyses of the dehydrated, K-saturated samples indicate that basal XRD reflections are broadened by symmetrical strain that may be related to local variations in smectite interlayers caused by dehydration, and that the standard deviation of the strain increases regularly with expandability. The 001 and 002 reflections are affected only slightly by this strain and therefore are suited for CSD thickness analysis. Mean mixed-layer crystal thicknesses for dehydrated I-S measured by the BWA method are very close to those measured by an integral peak width method.

    Cell wall polysaccharides of 'Scarlet Warren' winter squash ( Cucurbita maxima ) were investigated before and after thermal processing. Linkage analysis of polysaccharides was done by gas chromatography coupled to mass spectrometry (GC-MS). The linkage analysis showed the cell wall polysaccharide compositions of raw and cooked squash were similar. The total pectic polysaccharides (galacturonan, rhamnogalacturonan, arabinan, and arabinogalactan) contents of the cell walls of both raw and cooked squash were 39 mol %. The amounts of pectic polysaccharides and xyloglucan in the cell walls of squash showed little alteration on heating. The cellulose content of the raw and cooked cell walls was relatively high at 47 mol %, whereas the xyloglucan content was low at 4 mol %. Solid-state (13)C nuclear magnetic resonance (NMR) spectroscopy techniques were used to examine the molecular motion of the polysaccharides in the cell walls. The mobility of highly flexible galactan depends on the water content of the sample, but no difference was seen between raw and cooked samples. Likewise, the mobility of semimobile pectic polysaccharides was apparently unaltered by cooking. No change was detected in the rigid cellulose microfibrils on cooking.

  9. The effect of dietary fat on the fatty acid composition and cholesterol content of Hy-line and Warren hen eggs

    Full Text Available The present study analyzed the effect of dietary fat and strain on the fatty acid and cholesterol contents of eggs over a 20 month-period. Hy-line and Warren hens received three consecutive 7% lipid diets in which the basal constituents of the diet supplied 3% of the fats while the remaining 4% was composed of fats, oils or oleins added to progressively increase polyunsaturated fatty acid (PUFA levels, while decreasing dietary levels of both saturated fatty acids (SFA and monounsaturated fatty acids (MUFA. In general, the percentages of most fatty acids in egg lipids were affected by changes in dietary lipids but not by the strain. Data suggest the existence of a dietary threshold for elaidic acid to appear in eggs. Mufa decreased and total PUFA increased throughout the study. The cholesterol egg content was higher at the animal fat plus soybean oil than at the animal fat or the olein plus soybean oil blend. Overall, results showed that changes in dietary lipids influenced fatty acid composition and hence atherogenic and thrombogenic indexes much more than the strain.El objetivo del presente estudio fue analizar los efectos de la grasa de la dieta de dos estirpes de ponedoras (Hy-line y Warren sobre el contenido de ácidos grasos y colesterol del huevo durante un periodo del ciclo de puesta de 20 meses. Ambas estirpes recibieron 3 dietas consecutivas que contenían 7% de lípidos de los cuales 3% provenía de los componentes basales de la dieta y 4% fue adicionado en forma de grasa, aceites u oleínas con objeto de aumentar progresivamente el contenido de ácidos grasos poliinsaturados y disminuir el contenido de los ácidos grasos saturados y monoinsaturados. El cambio de grasa en la dieta afectó al perfil de la mayoría de los ácidos grasos del huevo, sugiriéndose la existencia de un mínimo de ácido elaídico en la grasa añadida para su aparición en el huevo.

    Increased demands for cleaner burning energy, coupled with the relatively recent technological advances in accessing hydrocarbon-rich geologic formations, have led to an intense effort to find and extract unconventional natural gas from various underground sources around the country. One of these sources, the Marcellus Shale, located in the Allegheny Plateau, is currently undergoing extensive drilling and production. The technology used to extract gas in the Marcellus Shale is known as hydraulic fracturing and has garnered much attention because of its use of large amounts of fresh water, its use of proprietary fluids for the hydraulic-fracturing process, its potential to release contaminants into the environment, and its potential effect on water resources. Nonetheless, development of natural gas extraction wells in the Marcellus Shale is only part of the overall natural gas story in this area of Pennsylvania. Conventional natural gas wells, which sometimes use the same technique for extraction, are commonly located in the same general area as the Marcellus Shale and are frequently developed in clusters across the landscape. The combined effects of these two natural gas extraction methods create potentially serious patterns of disturbance on the landscape. This document quantifies the landscape changes and consequences of natural gas extraction for Cameron, Clarion, Elk, Forest, Jefferson, McKean, Potter, and Warren Counties in Pennsylvania between 2004 and 2010. Patterns of landscape disturbance related to natural gas extraction activities were collected and digitized using National Agriculture Imagery Program (NAIP) imagery for 2004, 2005/2006, 2008, and 2010. The disturbance patterns were then used to measure changes in land cover and land use using the National Land Cover Database (NLCD) of 2001. A series of landscape metrics is also used to quantify these changes and is included in this publication. In this region, natural gas and oil development disturbed

    2013-01-01

    Between the late 1940s and 1994, groundwater levels in the Warren subbasin, California, declined by as much as 300 feet because pumping exceeded sparse natural recharge. In response, the local water district, Hi-Desert Water District, implemented an artificial-recharge program in early 1995 using imported water from the California State Water Project. Subsequently, the water table rose by as much as 250 feet; however, a study done by the U.S. Geological Survey found that the rising water table entrained high-nitrate septic effluent, which caused nitrate (as nitrogen) concentrations in some wells to increase to more than the U.S. Environmental Protection Agency maximum contaminant level of 10 milligrams per liter.. A new artificial-recharge site (site 3) was constructed in 2006 and this study, which started in 2004, was done to address concerns about the possible migration of nitrates in the unsaturated zone. The objectives of this study were to: (1) characterize the hydraulic, chemical, and microbiological properties of the unsaturated zone; (2) monitor changes in water levels and water quality in response to the artificial-recharge program at site 3; (3) determine if nitrates from septic effluent infiltrated through the unsaturated zone to the water table; (4) determine the potential for nitrates within the unsaturated zone to mobilize and contaminate the groundwater as the water table rises in response to artificial recharge; and (5) determine the presence and amount of dissolved organic carbon because of its potential to react with disinfection byproducts during the treatment of water for public use. Two monitoring sites were installed and instrumented with heat-dissipation probes, advanced tensiometers, suction-cup lysimeters, and wells so that the arrival and effects of recharging water from the State Water Project through the 250 to 425 foot-thick unsaturated zone and groundwater system could be closely observed. Monitoring site YVUZ-1 was located between two

    Full Text Available Cette étude a pour objet d’analyser un genre de discours spécialisé particulier au monde des entreprises. Les lettres aux actionnaires rédigées par Warren Buffett, dont la portée dépasse le cercle des actionnaires concernés, suscitent un intérêt hors du commun. Une analyse qualitative et quantitative portant sur le fond et la forme nous a permis de les comparer à un corpus témoin d’autres lettres aux actionnaires pour faire ressortir leur spécificité. La perspective diachronique qui a été adoptée nous a également donné l’occasion de mesurer l’évolution interne de ces documents sur une période de 32 ans. Les résultats de l’étude font ressortir une très grande présence de l’auteur dans son discours et la nature dialogique de ce discours. La « marqueterie discursive » atypique qui caractérise le style Buffett conduit également à envisager ses lettres comme des macro-actes de langage. Néanmoins, elles se rattachent sans ambiguïté au genre « lettre aux actionnaires » par la situation dans laquelle elles sont produites, le but qu’elles poursuivent et la fonction sociale qu’elles remplissent. Ce sont ces mêmes éléments qui permettent de les considérer comme un échantillon de discours spécialisé, même si leur syntaxe n’est pas spécifique et si le discours n’est pas particulièrement technique.The paper focuses on a particular genre which is characteristic of the corporate world. Warren Buffett’s letters to the shareholders seem to arouse unprecedented interest among readers who greatly outnumber his shareholders.

    Full Text Available RACIONAL: A hipertensão portal com sua principal complicação, a hemorragia digestiva alta varicosa, são importantes causas de morbimortalidade em cirróticos. A cirurgia de Teixeira-Warren é uma derivação portal seletiva, adotada em doentes Child-Pugh A e B para tratamento da hemorragia varicosa por hipertensão portal não responsiva à terapêutica clínico-endoscópica após o quadro agudo. O índice de congestão portal baseia-se em valores obtidos pela ultra-sonografia Doppler abdominal e encontra-se elevado em pacientes com hipertensão portal. OBJETIVO: Verificar se o índice de congestão portal e o grau de insuficiência hepática (Child-Pugh são fatores preditivos de recidiva hemorrágica após a cirurgia de Teixeira-Warren. MÉTODO: Em estudo longitudinal retrospectivo analisaram-se 62 prontuários de cirróticos operados pela técnica de Teixeira-Warren na Santa Casa de São Paulo. Foram submetidos a avaliação quanto ao índice de congestão portal pré-operatório 36 doentes, e 58 quanto à classe Child-Pugh. Os doentes foram divididos em grupos - com recidiva e ausência de recidiva hemorrágica - sendo analisada a diferença estatística quanto aos valores do índice e Child-Pugh pré-operatórios, relacionando-os à recidiva hemorrágica pós-operatória. RESULTADOS: Dos doentes que apresentaram recidiva hemorrágica, 69% eram Child B e possuíam índice de congestão portal médio de 0,09. Já entre aqueles que não ressangraram, 62% eram Child A e o índice de congestão portal médio foi de 0,076. A diferença foi estatisticamente significante para a classe Child-Pugh, porém, o mesmo não ocorreu para o índice de congestão portal. CONCLUSÃO: O índice de congestão portal no pré-operatório não foi fator preditivo de recidiva hemorrágica em cirróticos submetidos a cirurgia de Teixeira-Warren. Doentes classificados como Child-Pugh B possuem maior chance de recidiva hemorrágica pós-derivação esplenorrenal

    John Aldrich was born in Providence, Rhode Island, on 23 February 1906, and went to the Providence public schools. He developed a broad interest in natural history at an early age, being stimulated by his mother, a kindergarten teacher, who introduced him to nature books. His interest was strengthened by Harold L. Madison, Director of the Park Museum in Providence, an Associate ( = member) of the AOU. As a high school student, John taught nature study at the Rhode Island Boy Scout Camp in summers. John was President of his class at Classical High School, and manager of the school's football team in his senior year. Also in that year, 1923, John published his first paper, a note in Bird-Lore on the occurrence of the Mockingbird in Rhode Island. That paper is a literary gem, showing that his skill in writing developed as early as his knowledge of birds. His early interest in football continued as well; he was a devoted fan of the Washington Redskins in his later years.

    Full Text Available It is no accident that every political leader in current times is disappointing at best. The decline of state e ff i cacy has its source in the remarkable increase in the pace of world integration, or "globalization," that has occurred over the last two decades. Increased economic and cultural interpenetration across state boundaries is obvious to most observers. The surprise is short lived when wefind such ironies as that both sides in the 1992 Gulf War followed the battles on CNN, that Chinese studentsraised a "Statue of Liberty" during the 1989 protest inTiananmen Square, or that in 1994 the US dollar becamelegal tender in Cuba. With globalization has also comea somewhat less evident decline in a state's ability to manage its share of the world economy.

    2011-01-01

    The history of nuclear regulation is briefly reviewed to underscore the early recognition that independence of the regulator was essential in achieving and maintaining public credibility. The current licensing process is reviewed along with the status of applications. Challenges faced by both the NRC and the industry are reviewed, such as new construction techniques involving modular construction, digital controls replacing analog circuitry, globalization of the entire supply chain, and increased security requirements. The vital area of safety culture is discussed in some detail, and its importance is emphasized. Copyright © 2010 Health Physics Society

  17. Tenth Warren K. Sinclair keynote address-the Fukushima nuclear power plant accident and comprehensive health risk management.

    Science.gov (United States)

    Yamashita, Shunichi

    2014-02-01

    Just two years have passed since the Tokyo Electric Power Company-Fukushima Daiichi Nuclear Power Plant (NPP) accident, a multidimensional disaster that combined to destroy the local infrastructure on which the safety system depended and gave a serious impact to the world. Countermeasures including evacuation, sheltering, and control of the food chain were implemented in a timely manner by the Japanese government. However, there is a clear need for improvement, especially in the areas of nuclear safety and protection and also in the management of the radiation health risk during and even after the accident. To date there have been no acute radiation injuries. The radiation-related physical health consequences to the general public, including evacuees, are likely to be much lower than those arising from the Chernobyl nuclear reactor accident, because the radiation fallout and the subsequent environmental contamination were much more limited. However, the social, psychological, and economic impacts of the Fukushima NPP accident are expected to be considerable. Currently, continued monitoring and characterization of the levels of radioactivity in the environment and foods in Fukushima are vital for obtaining informed consent to the decisions on living in the areas already radiocontaminated and returning back to the evacuated areas once re-entry is permitted; it is also important to perform a realistic assessment of the radiation doses on the basis of measurements. We are currently implementing the official plans of the Fukushima Health Management Survey, which includes a basic survey for the estimation of the external doses that were received during the first 4 mo after the accident and four more detailed surveys (thyroid ultrasound examination, comprehensive health check-up, mental health and life-style survey, and survey of pregnant women and nursing mothers), with the aim to take care of the health of all of the residents of the Fukushima Prefecture for a long time.

    Directory of Open Access Journals (Sweden)

    A. A. Donohue

    2010-06-01

    Full Text Available This essay is an expanded version of a paper delivered in 1989 at a colloquium organized around a replica of the Doryphorus acquired by the Minneapolis Institute of Arts. Winckelmann's treatment of Polyclitus serves to introduce a wider consideration of the structure and method of his history of classical art. It is argued that, contrary to assertions that he developed his history on the basis of his empirical observation of works of classical art, Winckelmann instead adopted historiographic schemata derived directly and indirectly from ancient authors. The ancient texts themselves reflect not so much authentic information about the visual arts as formulations from a tradition of histories of the ‘technai’, the arts of civilization, that were often linked with political history. Pliny's famous statement of the decline of art is re-interpreted in this light.

Pre-consult forms, completed at the time of the request, examined reasons for the request and the clinical actions clinicians thought might be influenced by the search results. Requestors could opt out of the no CICS provided group either before or after the randomization of their request. Responses to requests, supplied within 0.5 to 7 days as agreed with the requestor, included a search strategy and bibliographic references, a targeted list of full-text articles, and a written synthesis and critique of the relevant research. Clinicians within both groups were free to conduct their own searches and reviews. An online evaluation form, emailed to recipients, was used to assess the impact of the information supplied. The evaluation form asked clinicians to record the time spent on their own searches, sources of information consulted including colleagues, the immediate and future impact of the information provided (either from the CICS or their own searches, what influence the information had on their clinical actions, whether there were any barriers to using the information, and quality and overall satisfaction with the results provided by the CICS. Data was analyzed according to the randomized group assignment using standard intention-to-treat analysis for the main outcomes between the two groups. Statistical adjustments were made to control for possible clustering of responses or multiple ratings from individual clinicians. The data was also analyzed on an efficacy basis depending on who provided the search results. The groups were Clinician only, CICS librarian-only, or Both Clinician and CICS librarian. Results from the Clinician only search group were used as a comparison to the remaining groups. This assessment did not take account of the randomization and therefore constitutes a cohort analysis. Results were analysed by one of two methods using statistical software SAS Proc Mixed (v9 for multi-level quantitative data analysis, e.g., analysis of variance, and SPSS (v14 for all other quantitative data analysis, including descriptive statistics.Main Results – The study period was conducted over 19 months: August 2004 to March 2006. During this time, 299 valid requests were received and 226 post consult evaluation forms were returned giving a response rate of 76%. Post consult forms were returned for 108/146 of the CICS provided group and 118/153 of the no CICS provided group. The 24% of requests that had no post consult evaluation were excluded from further analysis. Statistical tests, conducted to check for potential bias relating to missing data, suggested that the missing data had little impact on the findings.Medical and neonatal ICUs accounted for the majority of completed forms (40.3% and 38.1% respectively. The majority of opt-outs (10.2% overall were from the medical ICU. No significant difference in outcome variables was found between opt-out and other requests when tested using analysis of variance (ANOVA. Evaluation forms were completed by 89 unique clinicians and over half (49 submitted more than one request. The average requests per clinician was 2.96, SD 3.17, range 1-15, and the average number of requests per clinician who submitted more than one request was 4.57, SD 3.55, range 2-15. Total number of responses, mean, standard deviation, and Cohen’s d effect size were reported for the outcome variables based on intention to treat analysis. Results showed no significant difference between the groups on the immediate impact of the information provided, the number of articles read or the frequency with which clinicians consulted colleagues, either formally or informally. The potential future impact of the information was rated higher in the CICS group (p=Conclusion – Clinicians reported a higher level of satisfaction with search results provided by the CICS and rated the future impact of the information more highly. The CICS showed a statistically significant impact on some aspects of clinical decision-making, particularly with regard to treatment decisions. Provision of information by the CICS also appeared to encourage clinicians to undertake their own searches. However, the reasons for this are unclear.

    2015-02-01

    The valorization of spent hens via the food chain has some major limitations, which include low meat yield and tough meat. The latter issue can be overcome by producing convenience foods; the first may be alleviated by employing a genotype with higher meatiness. To quantitatively compare two common layer genotypes in production performance, meat yield and sausage quality, 2200 57 weeks old Institut de Sélection Animale (ISA) Warren and Dekalb White hens each were investigated during the last 60 days of egg laying. The hens were housed in an aviary system in 2×10 compartments (10 compartments/each genotype). Measurements included feed intake, laying performance, egg weight and feed conversion ratio as measured per compartment. BW was determined twice on 10 animals per compartment. Finally, two sub-groups of five hens per compartment were slaughtered, meat yield was recorded and bratwurst-type sausages were produced (n=20 per genotype). Fat proportion, cooking loss, connective tissue properties and Kramer shear energy were measured. After 1, 4, 7 and 10 months of frozen storage, oxidative stability (thiobarbituric acid reactive substances (TBARS)) and microbiological status were determined as shelf-life related criteria. ANOVA was performed considering genotype as the main effect. The ISA Warren hens were inferior in laying performance (-11%) and feed conversion ratio (+10%) compared with Dekalb White, but had the same feed intake. The ISA Warren had higher BW and carcass weight than the Dekalb White. Carcass yield was higher by 5.9%. There were 80 g (23%) more meat available for sausage production from ISA Warren compared with Dekalb White. Sausages prepared from meat of ISA Warren hens contained less fat than those from Dekalb White, but showed the same cooking loss. Although the collagen proportion of the sausages produced from ISA Warren was lower than from Dekalb White, collagen solubility was lower and shear energy was higher. During the 10 months of frozen

    Full Text Available This paper charts the Warren Court’s handling of those convicted for contempt of Congress at the urging of the House Un-American Activities Committee and the Senate Subcommittee on Internal Security. An examination of the arguments made in the Court’s various opinions—and by whom—reveals that the outcomes in these cases cannot be explained solely by the changing membership of the Court. Even when there were the votes to support the vigorous denunciations of the McCarthyite congressional investigations that found expression in dissents inspired by Watkins v. United States, the Warren Court took a more measured tone. That more measured tone was an attempt to avoid a repeat of the fractured Court amidst a public backlash that Warren had provoked with Watkins and marked a return to the Court’s pre-Watkins use of formalism to bring about the just result.

  6. Influence of cultivar, cooking, and storage on cell-wall polysaccharide composition of winter squash (Cucurbita maxima).

    Ratnayake, R M Sunil; Melton, Laurence D; Hurst, Paul L

    2003-03-26

    Changes in the cell-wall polysaccharides (CWP) of the edible tissues of four winter squash cultivars during storage and after cooking were investigated. A procedure for isolating cell walls of tissues containing high levels of starch was used. The starch-free CWP were sequentially fractionated using CDTA, dilute Na(2)CO(3), and 4 M KOH. Cellulose made up 40-42% of the total CWP for three cultivars (Delica, CF 2, and CF 4) at harvest but was 35% in the softer Red Warren. The pectic polysaccharides of Delica, CF 2, and CF 4 cell walls are more branched than those from Red Warren squash. The higher proportion of uronic acid in the pectic polysaccharides of Red Warren squash correlates with its lower firmness. Cooking resulted in an increase in the water-soluble pectins and a decrease in the pectins associated with cellulose. The total CWP content of the squash cultivars remained unchanged for up to 2 months of storage and then markedly decreased between 2 and 3 months of storage. The galactose content of Delica and Red Warren cell walls remained relatively constant from harvest to 2 months of storage and then decreased markedly during 2-3 months of storage.

  13. Bead-bead interaction parameters in dissipative particle dynamics: Relation to bead-size, solubility parameter, and surface tension

    Science.gov (United States)

    Maiti, Amitesh; McGrother, Simon

    2004-01-01

    Dissipative particle dynamics (DPD) is a mesoscale modeling method for simulating equilibrium and dynamical properties of polymers in solution. The basic idea has been around for several decades in the form of bead-spring models. A few years ago, Groot and Warren [J. Chem. Phys. 107, 4423 (1997)] established an important link between DPD and the Flory-Huggins χ-parameter theory for polymer solutions. We revisit the Groot-Warren theory and investigate the DPD interaction parameters as a function of bead size. In particular, we show a consistent scheme of computing the interfacial tension in a segregated binary mixture. Results for three systems chosen for illustration are in excellent agreement with experimental results. This opens the door for determining DPD interactions using interfacial tension as a fitting parameter.

  14. A new lumped-parameter approach to simulating flow processes in unsaturated dual-porosity media

    Energy Technology Data Exchange (ETDEWEB)

    Zimmerman, R.W.; Hadgu, T.; Bodvarsson, G.S. [Lawrence Berkeley Laboratory, CA (United States)

    1995-03-01

    We have developed a new lumped-parameter dual-porosity approach to simulating unsaturated flow processes in fractured rocks. Fluid flow between the fracture network and the matrix blocks is described by a nonlinear equation that relates the imbibition rate to the local difference in liquid-phase pressure between the fractures and the matrix blocks. This equation is a generalization of the Warren-Root equation, but unlike the Warren-Root equation, is accurate in both the early and late time regimes. The fracture/matrix interflow equation has been incorporated into a computational module, compatible with the TOUGH simulator, to serve as a source/sink term for fracture elements. The new approach achieves accuracy comparable to simulations in which the matrix blocks are discretized, but typically requires an order of magnitude less computational time.

  15. Study of High Lift Configurations

    2000-01-01

    This project focus on the implementation of the Warren-Hassan transition / turbulence model (Journal of Aircraft, Vol. 35, No. 5) into the NASA code CFL3D and its testing for multi-element airfoils in landing configuration at different angles of attack. The Warren-Hassan transition model solves an evolution equation for a kinetic energy characteristic of non-turbulent fluctuations. This is combined with an empirical estimate of the frequency of the most amplified first-mode disturbance to yield an expression for an eddy viscosity characteristic of non-turbulent fluctuations. This is combined with the k - zeta model for fully turbulent flow to yield a unified approach capable of predicting both transition onset and extent. Blending of the non-turbulent and turbulent components of the model is accomplished by an intermittency function based on the work of Dhawan and Narasimha (Journal of Fluid Mechanics, Vol. 3, No. 4).

    2011-01-01

    An unusual dark blue-green lichen, Lecanora sierrae, was discovered over 30 years ago by Czehura near copper mines in the Lights Creek District, Plumas County, Northern California. Using atomic absorption spectroscopy, Czehura found that dark green lichen samples from Warren Canyon contained 4% Cu in ash and suggested that its colour was due to copper accumulation in the cortex. The present study addressed the hypothesis that the green colour in similar material we sampled from Warren Canyon in 2008, is caused by copper localization in the thallus. Optical microscopy and electron microprobe analysis of specimens of L. sierrae confirmed that copper localization took place in the cortex. Elemental analyses of L. sierrae and three other species from the same localities showed high enrichments of copper and selenium, suggesting that copper selenates or selenites might occur in these lichens and be responsible for the unusual colour.

Here we show that, before him, Jastrow (1899, Popular Science Monthly 54 299-312) produced illusory contours consisting of a shadow word. A brief history of shadow writing in psychological literature from Jastrow to Brunswik is presented, in which the contributions of Pillsbury, Warren, Koffka, and Benussi are examined.

  11. Additions and corrections to the absorption coefficients of CO2 ice: Applications to the Martian south polar cap

    International Nuclear Information System (INIS)

    Calvin, W.M.

    1990-01-01

    Reflectance spectra of carbon dioxide frosts were calculated using the optical constants provided by Warren (1986) for the wavelength region 2-6 μm. In comparing these calculated spectra to spectra of frosts observed in the laboratory and on the surface of Mars, problems in the optical constants presented by Warren (1986) became apparent. Absorption coefficients for CO 2 ice have been derived using laboratory reflectance measurements and the Hapke (1981) model for calculating diffuse reflectance. This provides approximate values in regions where no data were previously available and indicates where corrections to the compilation by Warren (1986) are required. Using these coefficients to calculate the reflectance of CO 2 ice at varying grain sizes indicates that a typical Mariner polar cap spectrum is dominated by absorptions due to CO 2 frost or ice at grain sizes that are quite large, probably of the order of millimeters to centimeters. There are indications of contamination of water frost or dust, but confirmation will require more precise absorption coefficients for solid CO 2 than can be obtained from the method used here

  12. Factors affecting wild rabbit production in extensive breeding enclosures: how can we optimise efforts?

    Directory of Open Access Journals (Sweden)

    José Guerrero-Casado

    2013-09-01

    Full Text Available The declining rabbit population in the Iberian Peninsula has led hunters and authorities to rear rabbits in captivity systems for their subsequent release. One alternative method to intensive rabbitry systems is the use of extensive breeding enclosures, since they produce animals of greater quality for hunting and conservation purposes. However, some of the factors that affect rabbit production in breeding enclosures are still unknown. The present study used partial least squares regression (PLSR to analyse the effects of plot size, scrub cover, slope, initial rabbit abundance, the resources needed to dig warrens, predation and proximity to other enclosures on rabbit abundance. The results of our study show a positive effect of the number of other fenced plots within a radius of 3 km, a positive relationship with the availability of optimal resources for building warrens and a positive influence of intermediate values of scrub cover. According to our results, to maximise rabbit production in the enclosures it would be advisable to concentrate the restocking effort by ensuring that the restocking plots are close to each other, thus avoiding isolated enclosures. Furthermore, the selection of plots with an appropriate scrub cover and high availability of elements that favour the construction of warrens, such as large stones, sloping land or tall shrubs, may optimise results.

  13. Snow Climatology of Arctic Sea Ice: Comparison of Reanalysis and Climate Model Data with In Situ Measurements

    Science.gov (United States)

    Chevooruvalappil Chandran, B.; Pittana, M.; Haas, C.

    2015-12-01

    Snow on sea ice is a critical and complex factor influencing sea ice processes. Deep snow with a high albedo and low thermal conductivity inhibits ice growth in winter and minimizes ice loss in summer. Very shallow or absent snow promotes ice growth in winter and ice loss in summer. The timing of snow ablation critically impacts summer sea ice mass balance. Here we assess the accuracy of various snow on sea ice data products from reanalysis and modeling comparing them with in situ measurements. The latter are based on the Warren et al. (1999) monthly climatology derived from snow ruler measurements between 1954-1991, and on daily snow depth retrievals from few drifting ice mass balance buoys (IMB) with sufficiently long observations spanning the summer season. These were compared with snow depth data from the National Center for Environmental Prediction Department of Energy Reanalysis 2 (NCEP), the Community Climate System Model 4 (CCSM4), and the Canadian Earth System Model 2 (CanESM2). Results are quite variable in different years and regions. However, there is often good agreement between CanESM2 and IMB snow depth during the winter accumulation and spring melt periods. Regional analyses show that over the western Arctic covered primarily with multiyear ice NCEP snow depths are in good agreement with the Warren climatology while CCSM4 overestimates snow depth. However, in the Eastern Arctic which is dominated by first-year ice the opposite behavior is observed. Compared to the Warren climatology CanESM2 underestimates snow depth in all regions. Differences between different snow depth products are as large as 10 to 20 cm, with large consequences for the sea ice mass balance. However, it is also very difficult to evaluate the accuracy of reanalysis and model snow depths due to a lack of extensive, continuous in situ measurements.

    This work studies the structural evolution of Cu-xCr (x = 3, 5 and 8 wt.%) alloys processed by mechanical alloying using X-ray diffraction profiles, scanning microscopy and microhardness analysis. X-ray diffraction analysis using the modified Williamson-Hall and Warren-Averbach methods were used to determine structural properties, such as crystallite size, stacking fault probability and energy, dislocation density, lattice parameters and crystallite size distribution of metallic powder as a function of Cr amount and milling time. Lattice defects increase the Gibbs free energy and the Gibbs free energy curves shift upward, therefore the solubility limit change.

    The California Attorney General found three sections of the state's nuclear regulation code to be in violation of Federal authority and the State Constitution. Legislation and court cases since 1946 are quoted to support the Attorney General's position. The Warren--Alquist Act, which requires a demonstrated technology for reprocessing fuel rods or disposing of high-level wastes before a nuclear plant can be licensed, is unconstitutional because it usurps Federal control and allows the state to permanently block nuclear facility construction and certification. States' rights in the area of radiological health and safety are supplanted by the Federal government

    2016-06-25

    Peptic ulcer disease is one of the most commonly encountered diseases in gastroenterology clinics. After the discovery of Helicobacter pylori by Warren and Marshall, it has been identified as the most important cause of peptic ulcer. Eradication of H. pylori markedly reduces the post-treatment recurrence rate of peptic ulcer. However, as human populations age, the incidence of cardiovascular and musculoskeletal diseases increases and consequent use of aspirin and non-steroidal anti-in-flammatory drugs increases. Thus causes and presenting patterns of peptic ulcer have changed. In this review, I describe new diagnostic and therapeutic strategies for peptic ulcer disease and explore future perspectives.

At the same time, while objects and their properties belong to the domain of physics, I will use some basic symmetry concepts from physics. Correlation then takes the form of an interwoven fabric where cause and effect are entangled. Different subsistence practices will correlate with different symmetries, i.e. translational and rotational symmetries, of the sky universe, that can be recognized from artistic expressions like personal ornaments.

    If you wander through the warren of galleries on the fifth floor of the Museum of Modern Art (MoMA) in New York, you encounter some of the most famous artworks of the late 19th and early 20th century. Vincent Van Gogh's Starry Night hangs in one room, Salvador Dali's The Persistence of Memory in another, Henri Matisse's Dance in a third. You will walk through a roomful of Piet Mondrian compositions, including Broadway Boogie Woogie, and it seems like every other painting is by Pablo Picasso, including his Les Demoiselles d'Avignon.

  12. Velocity and stress autocorrelation decay in isothermal dissipative particle dynamics

    Science.gov (United States)

    Chaudhri, Anuj; Lukes, Jennifer R.

    2010-02-01

    The velocity and stress autocorrelation decay in a dissipative particle dynamics ideal fluid model is analyzed in this paper. The autocorrelation functions are calculated at three different friction parameters and three different time steps using the well-known Groot/Warren algorithm and newer algorithms including self-consistent leap-frog, self-consistent velocity Verlet and Shardlow first and second order integrators. At low friction values, the velocity autocorrelation function decays exponentially at short times, shows slower-than exponential decay at intermediate times, and approaches zero at long times for all five integrators. As friction value increases, the deviation from exponential behavior occurs earlier and is more pronounced. At small time steps, all the integrators give identical decay profiles. As time step increases, there are qualitative and quantitative differences between the integrators. The stress correlation behavior is markedly different for the algorithms. The self-consistent velocity Verlet and the Shardlow algorithms show very similar stress autocorrelation decay with change in friction parameter, whereas the Groot/Warren and leap-frog schemes show variations at higher friction factors. Diffusion coefficients and shear viscosities are calculated using Green-Kubo integration of the velocity and stress autocorrelation functions. The diffusion coefficients match well-known theoretical results at low friction limits. Although the stress autocorrelation function is different for each integrator, fluctuates rapidly, and gives poor statistics for most of the cases, the calculated shear viscosities still fall within range of theoretical predictions and nonequilibrium studies.

  13. Event-based plausibility immediately influences on-line language comprehension.

    In some theories of sentence comprehension, linguistically relevant lexical knowledge, such as selectional restrictions, is privileged in terms of the time-course of its access and influence. We examined whether event knowledge computed by combining multiple concepts can rapidly influence language understanding even in the absence of selectional restriction violations. Specifically, we investigated whether instruments can combine with actions to influence comprehension of ensuing patients of (as in Rayner, Warren, Juhuasz, & Liversedge, 2004; Warren & McConnell, 2007). Instrument-verb-patient triplets were created in a norming study designed to tap directly into event knowledge. In self-paced reading (Experiment 1), participants were faster to read patient nouns, such as hair, when they were typical of the instrument-action pair (Donna used the shampoo to wash vs. the hose to wash). Experiment 2 showed that these results were not due to direct instrument-patient relations. Experiment 3 replicated Experiment 1 using eyetracking, with effects of event typicality observed in first fixation and gaze durations on the patient noun. This research demonstrates that conceptual event-based expectations are computed and used rapidly and dynamically during on-line language comprehension. We discuss relationships among plausibility and predictability, as well as their implications. We conclude that selectional restrictions may be best considered as event-based conceptual knowledge rather than lexical-grammatical knowledge.

  14. Application of the maximum entropy method to profile analysis

    International Nuclear Information System (INIS)

    Armstrong, N.; Kalceff, W.; Cline, J.P.

    1999-01-01

    Full text: A maximum entropy (MaxEnt) method for analysing crystallite size- and strain-induced x-ray profile broadening is presented. This method treats the problems of determining the specimen profile, crystallite size distribution, and strain distribution in a general way by considering them as inverse problems. A common difficulty faced by many experimenters is their inability to determine a well-conditioned solution of the integral equation, which preserves the positivity of the profile or distribution. We show that the MaxEnt method overcomes this problem, while also enabling a priori information, in the form of a model, to be introduced into it. Additionally, we demonstrate that the method is fully quantitative, in that uncertainties in the solution profile or solution distribution can be determined and used in subsequent calculations, including mean particle sizes and rms strain. An outline of the MaxEnt method is presented for the specific problems of determining the specimen profile and crystallite or strain distributions for the correspondingly broadened profiles. This approach offers an alternative to standard methods such as those of Williamson-Hall and Warren-Averbach. An application of the MaxEnt method is demonstrated in the analysis of alumina size-broadened diffraction data (from NIST, Gaithersburg). It is used to determine the specimen profile and column-length distribution of the scattering domains. Finally, these results are compared with the corresponding Williamson-Hall and Warren-Averbach analyses. Copyright (1999) Australian X-ray Analytical Association Inc

    A cell recycle fermentor using a cross-flow membrane filter has been operated for extended periods. Productivities as high as 70 g/l/h were obtained at a cell concentration of 120 g/l and a product concentration of 70 g/l. The experimental results were then fitted to previously derived biokinetic models (Warren et al., 1990) for a continuous stirred tank fermentor. A good fit for growth rate was found and the cell yield was shown to decrease with product concentration. The product yield, however, was found to remain nearly constant at all cell, substrate and product concentrations. These biokinetics, along with a previous model for the membrane filter (Warren et al., 1991) were then used in a simulalation to estimate the costs of producing ethanol in a large scale system. This simulation was optimized using a variant of the steepest descent method from which a fermentor inlet substrate concentration of 150 g/l and a net cost of $CAN 253.5/1000 L ethanol were projected. From a sensitivity analysis, the yield parameters were found to have the greatest effect on ethanol net cost of the fermentor parameters, while the operating costs and the profit was found to be most sensitive to the wheat raw material cost and to the dried grains by-product value. 55 refs., 11 tabs., 7figs.

The demonstrations also put {open_quotes}environmental racism{close_quotes} on the map and challenged the myth that African Americans are not concerned about or involved in environmental issues. Grassroots groups, after decades of struggle, have grown to become the core of the multi-issue, multiracial, and multi-regional environmental justice movement. Diverse community-based groups have begun to organize and link their struggles to issues of civil and human rights, land rights and sovereignty, cultural survival , racial and social justice, and sustainable development. The impetus for getting environmental justice on the nations`s agenda has come from an alliance of grassroots activists, civil rights leaders, and a few academicians who questioned the foundation of the current environmental protection paradigm--where communities of color receive unequal protection. Whether urban ghettos and barrios, rural {open_quotes}poverty pockets,{close_quotes} Native American reservations, or communities in the Third World, grassroots groups are demanding an end to unjust and nonsustainable environmental and development policies.

  17. Application of the θ-method to a telegraphic model of fluid flow in a dual-porosity medium

    González-Calderón, Alfredo; Vivas-Cruz, Luis X.; Herrera-Hernández, Erik César

    2018-01-01

    This work focuses mainly on the study of numerical solutions, which are obtained using the θ-method, of a generalized Warren and Root model that includes a second-order wave-like equation in its formulation. The solutions approximately describe the single-phase hydraulic head in fractures by considering the finite velocity of propagation by means of a Cattaneo-like equation. The corresponding discretized model is obtained by utilizing a non-uniform grid and a non-uniform time step. A simple relationship is proposed to give the time-step distribution. Convergence is analyzed by comparing results from explicit, fully implicit, and Crank-Nicolson schemes with exact solutions: a telegraphic model of fluid flow in a single-porosity reservoir with relaxation dynamics, the Warren and Root model, and our studied model, which is solved with the inverse Laplace transform. We find that the flux and the hydraulic head have spurious oscillations that most often appear in small-time solutions but are attenuated as the solution time progresses. Furthermore, we show that the finite difference method is unable to reproduce the exact flux at time zero. Obtaining results for oilfield production times, which are in the order of months in real units, is only feasible using parallel implicit schemes. In addition, we propose simple parallel algorithms for the memory flux and for the explicit scheme.

    One goal of the European Space Agency Climate Change Initiative sea ice Essential Climate Variable project is to provide a quality controlled 20 year long data set of Arctic Ocean winter-time sea ice thickness distribution. An important step to achieve this goal is to assess the accuracy of sea ice thickness retrieval based on satellite radar altimetry. For this purpose a data base is created comprising sea ice freeboard derived from satellite radar altimetry between 1993 and 2012 and collocated observations of snow and sea ice freeboard from Operation Ice Bridge (OIB) and CryoSat Validation Experiment (CryoVEx) air-borne campaigns, of sea ice draft from moored and submarine Upward Looking Sonar (ULS), and of snow depth from OIB campaigns, Advanced Microwave Scanning Radiometer aboard EOS (AMSR-E) and the Warren Climatology (Warren et al., 1999). An inter-comparison of the snow depth data sets stresses the limited usefulness of Warren climatology snow depth for freeboard-to-thickness conversion under current Arctic Ocean conditions reported in other studies. This is confirmed by a comparison of snow freeboard measured during OIB and CryoVEx and snow freeboard computed from radar altimetry. For first-year ice the agreement between OIB and AMSR-E snow depth within 0.02 m suggests AMSR-E snow depth as an appropriate alternative. Different freeboard-to-thickness and freeboard-to-draft conversion approaches are realized. The mean observed ULS sea ice draft agrees with the mean sea ice draft computed from radar altimetry within the uncertainty bounds of the data sets involved. However, none of the realized approaches is able to reproduce the seasonal cycle in sea ice draft observed by moored ULS satisfactorily. A sensitivity analysis of the freeboard-to-thickness conversion suggests: in order to obtain sea ice thickness as accurate as 0.5 m from radar altimetry, besides a freeboard estimate with centimetre accuracy, an ice-type dependent sea ice density is as mandatory

    Full Text Available Introduction: Hypersplenism is a common complication of portal hypertension. Cytopenia in hypersplenism is predominantly caused by splenomegaly. Distal splenorenal shunt (Warren with partial spleen resection is an original surgical technique that regulates cytopenia by reduction of the enlarged spleen. Objective. The aim of our study was to present the advantages of distal splenorenal shunt (Warren with partial spleen resection comparing morbidity and mortality in a group of patients treated by distal splenorenal shunt with partial spleen resection with a group of patients treated only by a distal splenorenal shunt. Method. From 1995 to 2003, 41 patients with portal hypertension were surgically treated due to hypersplenism and oesophageal varices. The first group consisted of 20 patients (11 male, mean age 42.3 years who were treated by distal splenorenal shunt with partial spleen resection. The second group consisted of 21 patients (13 male, mean age 49.4 years that were treated by distal splenorenal shunt only. All patients underwent endoscopy and assessment of oesophageal varices. The size of the spleen was evaluated by ultrasound, CT or by scintigraphy. Angiography was performed in all patients. The platelet and white blood cell count and haemoglobin level were registered. Postoperatively, we noted blood transfusion, complications and total hospital stay. Follow-up period was 12 months, with first checkup after one month. Results In the first group, only one patient had splenomegaly postoperatively (5%, while in the second group there were 13 patients with splenomegaly (68%. Before surgery, the mean platelet count in the first group was 51.6±18.3x109/l, to 118.6±25.4x109/l postoperatively. The mean platelet count in the second group was 67.6±22.8x109/l, to 87.8±32.1x109/l postoperatively. Concerning postoperative splenomegaly, statistically significant difference was noted between the first and the second group (p<0.05. Comparing the

    2014-01-01

    There is a lot of confusion and misconception concerning science. The nature and contents of science is an unsettled problem. For example, Thales of 2,600 years ago is recognized as the father of science but the word science was introduced only in the 14th century; the definition of science is often avoided in books about philosophy of science. This book aims to clear up all these confusions and present new developments in the philosophy, history, sociology and communication of science. It also aims to showcase the achievement of China's top scholars in these areas. The 18 chapters, divided into five parts, are written by prominent scholars including the Nobel laureate Robin Warren, sociologist Harry Collins, and physicist-turned-historian Dietrich Stauffer.

    1985-01-01

    Twenty-four patients with chronic liver diseases and seven normal controls were studied using renal and hepatic radiotechnetium angiography. The time-activity histograms generated were employed to calculate both the renal perfusion index (RPI) and the hepatic perfusion index (HPI). Renal perfusion proved to be reduced not only in cirrhotic patients but also in patients with aggressive chronic hepatitis, as well as in those with persistent chronic hepatitis. The HPI, which is to be considered as being strictly dependent on portal flow, only fell significantly in the group of cirrhotic patients. In all patient groups, the correlation coefficient between the HPI and RPI (mean of the two kidneys) was low (r=0.275) and not significant (P>0.05). After Warren's splenorenal derivation, renal perfusion did not improve but worsened, particularly in the left kidney where derivation anastomosis probably caused a venous overload. (orig.)

  8. Laser-perturbed nuclear magnetic resonance spectroscopy and the conservation of parity

    Harris, R.A.; Tinoco, I. Jr.

    1994-01-01

    The effect of polarized incident light on NMR spectra is evaluated; shifts in energy levels and changes in population are calculated. For unoriented systems there is no effect of the amplitude of the field of the light on NMR spectra. The effect of light intensity on NMR spectra produces negligible changes in chemical shifts; fractional changes of less than 10 -6 are calculated for light intensities of 10 W cm -2 . The fundamental concept of conservation of parity is used to obtain general conclusions about the effect of light on NMR spectra of optical isomers. The NMR spectrum of a molecule in right circularly polarized light must be the same as its mirror image molecule in left circularly polarized light. A recent report [Warren et al., Science 255, 1683 (1992)] gives experimental results which are not consistent with any of these conclusions

    Full Text Available Abstract The Gram negative curved bacillus H. pylori has become the prize bug of all times. Barry Marshall and Robin Warren the two discoverers of this organism have been awarded with this year's Nobel Prize. The Nobel committee at the Karolinska Institute of Sweden has selected this paradigm shift discovery of 1982 as the most impacting in medical sciences. This award has surprised many as the Nobel assembly has selected this 'Robert Koch styled medical detective work' for the prize as compared to many outstanding basic research stories on the waitlist. This editorial briefly touches the significant impact of H. pylori on gastroduodenal management and the path forward as the bug has become quite controversial in recent times.

    1978-12-01

    Outbreaks of myxomatosis during the winter or spring have coincided with the establishment of the European rabbit flea in the Mallee region. The severity of these outbreaks has varied from causing complete suppression of the normal spring increase in rabbit numbers to being completely ineffective in a year in which late spring rains allowed rabbit breeding to extend into the early summer.In 1973 and 1974 effective spring myxomatosis caused heavy mortality in kittens before they emerged from the warrens. The age of the population increased as the result of few young rabbits coming into the population and of the lessened stress on old rabbits in a low summer-autumn population. This effect was reversed in the late-breeding year, 1976, when flea numbers were apparently too low to maintain a spring outbreak and rabbit numbers increased rapidly.

    Most frequent complications in patients with liver cirrhosis are due to portal hypertension. Beside ascites circumvent vessles formate with vasodilatation. Due to counterregulation a secondary hyperaldosteronism develops with release of vasocontrictive agents. If conservative and endoscopic methods fail, indication for building a portosystemic shunt is given. The TIPSS procedure is less invasive than the surgical method of Warren-Shunt, so the radiological intervention has replaced surgery. Reducing the portal pressure by the shunt, the clinical complications change for the better. Still problems are defined as hepatic encephalopathy and right ventricular heart failure. Regular follow up investigations have to be performed to detect complications in the shunt. Using regular clinical and radiological check up TIPSS is of clinical benefit with good long term results.

  13. On the measurement of the stacking-fault energies of face centered cubic metal and austenitic stainless steels by X-ray diffraction

    International Nuclear Information System (INIS)

    Borges, J.F.A.

    1985-01-01

    An X-rays diffraction method was applied to measure the Stacking-Fault Energies (SFE) of the AISI 304, AISI 316, AISI 347 and DIN-WERKSTOFF 1.4970 Austenitic Stainless Steels. The SFE determination plays an important role in the research of the mechanical behaviour of the Metal and Alloys, their deformation mechanisms, stability of microstructure amd electronic configuration. The method is based on the relationship between the SFE and the ratio of the Mean Square Strain to the Stacking-Fault probability. The Mean Square Strain was evaluated by Fourier Analysis of X-rays Diffraction profiles, corrected to reduce instrumental effects, followed by the application of the Warren-Averbach method to the Fourier Coefficients. The Stacking-Fault probabilities were derived from the changes of peak separations between cold-worked and annealed specimens. (author) [pt

    1986-01-01

    Herpesvirus papio (HVP) and Epstein-Barr virus (EBV) are closely related biologically and biochemically; lymphoblastoid cells infected with either virus contain episomal viral DNA. The putative origin of replication for EBV plasmids (oriP) has been assigned to a 1,790-base-pair fragment (cis) in the short unique region of the genome which requires a viral function supplied in trans from elsewhere in the genome (J. Yates, N. Warren, D. Reisman, and B. Sugden, Proc. Natl. Acad. Sci. USA 81:3806-3810, 1984). We report here the identification of the putative origin of replication (cis) in HVP; we assigned it to the HVP EcoRI K fragment. The results indicate that the HVP replication process requires both a cis and a trans-acting function, analogous to that found in EBV. Images PMID:3023667

    The correlation between 29 Si chemical shifts and Si-O-Si bond angles in SiO 2 is determined within density-functional theory for the full range of angles present in vitreous silica. This relation closely reproduces measured shifts of crystalline polymorphs. The knowledge of the correlation allows us to reliably extract from the experimental NMR spectrum the mean (151 degree sign ) and the standard deviation (11 degree sign ) of the Si-O-Si angular distribution of vitreous silica. In particular, we show that the Mozzi-Warren Si-O-Si angular distribution is not consistent with the NMR data. This analysis illustrates the potential of our approach for structural determinations of silicate glasses. (c) 2000 The American Physical Society

    Full Text Available Women photographers made considerable contributions to the ‘age of emulsion’ that transformed the way art history was practiced and taught early in the twentieth century. Among American women who made great efforts to record medieval monuments were Vida Hunt Francis, who worked in France c. 1905-15, and Lucy Warren Porter whose work has previously been attributed to her husband, Arthur Kingsley Porter. Georgiana Goddard King of Bryn Mawr College preceded Porter and others in documenting medieval and renaissance sites for the Hispanic Society of America. Her co-photographer Edith H. Lowber has until now been overlooked. The last book they planned together was edited and published posthumously and most of the illustrations they prepared for it remained unpublished. King also had a great interest in modern art, through her friendship with Gertrude Stein. Occasionally the photos recall cubism, and some of her writing verges on modernist écriture feminine.

    The present work looks into the microstructural modification in electron irradiated Bombyx mori P31 silk fibers. The irradiation process was performed in air at room temperature using 8 MeV electron accelerator at different doses: 0, 25, 50 and 100 kGy. Irradiation of polymer is used to cross-link or degrade the desired component or to fix the polymer morphology. The changes in microstructural parameters in these natural polymer fibers have been computed using wide angle X-ray scattering (WAXS) data and employing line profile analysis (LPA) using Fourier transform technique of Warren. Exponential, Lognormal and Reinhold functions for the column length distributions have been used for the determination of crystal size, lattice strain and enthalpy parameters.

    Since its formation, the Office of Health (EH-40) has stressed the importance of the exchange of information related to and improvements in neutron dosimetry. This Workshop was the eleventh in the series sponsored by the Department of Energy (DOE). It provided a forum for operational personnel at DOE facilities to discuss current issues related to neutron dosimetry and for leading investigators in the field to discuss promising approaches for future research. A total of 26 papers were presented including the keynote address by Dr. Warren K. Sinclair, who spoke on, ''The 1990 Recommendations of the ICRP and their Biological Background.'' The first several papers discussed difficulties in measuring neutrons of different energies and ways of compensating or deriving correction factors at individual facilities. Presentations were also given by the US Navy and Air Force. Current research in neutron dosimeter development was the subject of the largest number of papers. These included a number on the development of neutron spectrometers

The total volume and rate of water that leaked past the earplug and subsequent defect in the tympanic membrane over separately measured 30, 60, 120, and 180-second intervals were recorded. Scenarios tested included a control with no earplug, custom molded earplug (Precision Laboratories, Orlando, FL), Mack's plug (Warren, MI), Doc's plug (Santa Cruz, CA), and cotton balls coated with petroleum jelly. All plugs tested resulted in less leakage at all time points when compared with no plug (P leakage when compared with the cotton ball coated with petroleum jelly (P leakage compared with the customized plug (P leakage than the cotton plug (P leakage rate (f(4,45) = 94 [P water exposure should be minimized, then use of earplugs, particularly the moldable variety, merits further consideration.

    2015-09-01

    To confront the challenges facing modern health care, experts and organizations are calling for an increase in physician leadership capabilities. In response to this need, physician leadership programs are proliferating, targeting all levels of experience at all levels of training. Many academic medical centers, major universities, and specialty societies now sponsor physician leadership training programs. To meet this need, The Warren Alpert Medical School of Brown University, as part of its Primary Care-Population Medicine (PC-PM) Program, designed a four-year integrated curriculum, Leadership in Health Care, to engage with leadership topics starting early in the preclinical stages of training. This paper describes the design and implementation of this leadership curriculum for PC-PM students.

    1995-05-01

    When 500 demonstrators gathered in 1982 to protest the siting of a polychlorinated-biphenyl landfill in predominantly black Warren County, N.C., cries of environmental racism filled the air. In response, District of Columbia Congressional Delegate Walter Fauntroy requested that the General Accounting Office investigate a possible link between hazardous waste landfill siting and the racial and socio-economic mix of surrounding communities. The environmental justice movement, as it is known today, had been born. Environmental justice is conceived as the right of all people--regardless of race, ethnicity, culture or income--to live in a healthy environment, breathe clean air, drink clean water and eat uncontaminated foods. The concept assumes that everyone is entitled to fair environmental protection without any population segment bearing a disproportionate pollution burden.

    2018-06-01

    The microstructure evolution due to thermomechanical treatment of metals can largely be described by viscoplastic deformation, nucleation and grain growth. These processes take place over different length and time scales which present significant challenges when formulating simulation models. In particular, no overall unified field framework exists to model concurrent viscoplastic deformation and recrystallization and grain growth in metal polycrystals. In this work a thermodynamically consistent diffuse interface framework incorporating crystal viscoplasticity and grain boundary migration is elaborated. The Kobayashi-Warren-Carter (KWC) phase field model is extended to incorporate the full mechanical coupling with material and lattice rotations and evolution of dislocation densities. The Cosserat crystal plasticity theory is shown to be the appropriate framework to formulate the coupling between phase field and mechanics with proper distinction between bulk and grain boundary behaviour.

    The Draw-A-Person Test was individually administered to 120 kindergartners from diverse socioeconomic backgrounds, ranging in age from 4 yr. and 10 mo. to 6 yr. and 4 mo. This study was conducted to validate and expand Goldman and Warren's earlier work (1976) on the development of a rational scale for use as a kindergarten screening measure. Correlational analyses corroborate the earlier findings that body-part omissions are the most predictive items of emotional high risk. Factor analyses of the current data also replicate earlier findings in which two underlying cohesive factors emerged. The first factor has high loadings on peripheral body-part omissions; the second factor has high loadings on central body-part omission. The results suggest that an interchangeable number of body-part omissions together, rather than any one item, predict high emotional risk. Structural and content characteristics do not contribute significantly to the development of a kindergarten screening measure.

    Terrestrial and aquatic volcanic oligotrophic environments can host microorganisms that obtain their energy from reduced inorganic chemicals present in volcanic rocks and soils. We sampled basaltic rock from terrestrial Dark Oligotrophic Volcanic Ecosystems (DOVEs) located in two fumarole ice caves, Warren and Warren West, located near the summit of Mt. Erebus, Antarctica. For reference, we sampled a similar cave, Harry's Dream, which receives continuous light during the Austral summer. We report here culturing data for bacterial and eukaryotic microbes from rocky soils in these caves when targeting lithotrophic organisms using media containing reduced inorganic compounds (Mn2+, Fe2+, NH4+). In addition, to test for the possible presence of inorganic carbon fixation, we screened samples for the ribulose-1,5-bisphosphate carboxylase/oxygenase (RuBisCO) gene. Culturing of soil samples on media targeting both autotrophs and heterotrophs yielded a diverse collection of generally slow-growing colonies of bacteria (majority), fungi and non-fungal eukaryotes. Manganese(II)-oxidizing colonies were identified in Warren and Harry's Dream, and these exhibited two colony morphotypes upon subculturing. Sequencing of the PCR amplified 16S rRNA gene identified a bacterium distantly related to Pseudonocardia sp., a genus with known manganese oxidizers. Other bacteria enriched included members of the Actinobacteria, Alphaproteobacteria and Betaproteobacteria. There was a low diversity in cultured eukaryotes representing several potential undescribed species (Geomyces sp., Penicillium sp.) and isolates that may represent alternate, previously undescribed habitats and forms (Psilolechia leprosa, Alternaria alternata). One Warren isolate was a 99% 16S rRNA match to the N2 fixer Bradyrhizobium sp.; when inoculated into liquid medium specific for N2 fixers, growth was maintained upon subculture. Putative iron oxidizers were also enriched from the two DOVE caves, using slush agar iron

  15. Convergence of Wachspress coordinates: from polygons to curved domains

    2014-08-08

    Given a smooth, strictly convex planar domain, we investigate point-wise convergence of the sequence of Wachspress coordinates defined over finer and finer inscribed polygonal approximations of the domain. Based on a relation between the discrete Wachspress case and the limit smooth case given by the Wachspress kernel defined by Warren et al., we show that the corresponding sequences of Wachspress interpolants and mappings converge as 𝓞(h2) for a sampling step size h of the boundary curve of the domain as h → 0. Several examples are shown to numerically validate the results and to visualise the behaviour of discrete interpolants and mappings as they converge to their smooth counterparts. Empirically, the same convergence order is observed also for mean value coordinates. Moreover, our numerical tests suggest that the convergence of interpolants and mappings is uniform both in the Wachspress and mean value cases. © 2014 Springer Science+Business Media New York.

    Postoperative pancreatic fistula (POPF) and its complications remain problems. This study evaluated combination treatment with modified Blumgart anastomosis and an original infection control method (complete packing method) following pancreatic head resection. This study included 374 consecutive patients who underwent pancreatic head resection: 103 patients underwent Cattell-Warren anastomosis (CWA); 170 patients underwent modified Kakita anastomosis (KA); and 101 patients underwent modified Blumgart anastomosis with the complete packing method (BAC). The outcomes of the KA and BAC groups were compared statistically. The POPF rate was significantly lower in the BAC group than in the KA group (28.8% vs 2.97%; p anastomosis and the complete packing method is a simple and useful method for reducing the incidence of POPF and postoperative complications.

    This paper reports on extended electron energy-loss fine structure (EXELFS) that has been used to measure short-range ordering in Ni 3 Al. Films of fcc Ni 3 Al with suppressed short-range order synthesized by vacuum evaporation of Ni 3 Al onto room temperature substrates. EXELFS data were taken from both Al K and Ni L 23 edges. The development of short-range order was observed after the samples were annealed for various times at temperatures below 350 degrees C. Upon comparison with ab initio planewave EXELFS calculations, it was found that the Warren-Cowley short-range order parameter a(1nn) changed by about -0.1 after 210 minutes of annealing at 150 degrees C

    1993-01-01

    Warren Spring Laboratory and BMT Ceemaid Ltd. are cooperating to produce an Oil Spill Information System (OSIS) that will have worldwide application. OSIS is based on EUROSPILL, a spill simulation model originally developed under programs sponsored by the European Commission and the Marine Pollution Control Unit of the United Kingdom government's Department of Transport. OSIS is implemented in the Microsoft Windows 3.x graphical environment on a personal computer. A variety of options enables the user to input information on continuous or instantaneous spills of different types of oil under variable environmental conditions, to simulate the fate of oil and the trajectory of a spill. Model results are presented in the forms of maps, charts, graphs, and tables, displayed in multiple windows on a color monitor. Color hard copy can be produced, and OSIS can be linked to other Windows software packages, providing the opportunity to create a suite of spill incident management tools

    Data were acquired in service mode during UT 2014 May 23-June 7 using VLT/SINFONI observations. We used two of SINFONI's four gratings providing spectral resolutions R=3000 and 4000 in the H and K bands, respectively, with the field of view of 8" by 8" (without adaptive optics). The targets are 55 MIPSGAL "bubbles" (MBs) that have not been previously classified as PNe, whose central sources were unidentified at the time of the Period 93 Call for Proposals (UT 2013 October 01), and appeared to contain at least one potential central source detected in the near-IR images of the Two Micron All-Sky Survey (2MASS, Skrutskie et al. 2006, Cat. VII/233) or the UKIRT Infrared Deep Sky Survey (UKIDSS, Warren et al. 2007MNRAS.381.1400W). (5 data files).

    This article responds to commentaries written by Warren Tryon (2016) and Arthur Staats (2016) concerning Schwartz, Lilienfeld, Meca, and Sauvigné (2016). In this reply, we reiterate our key thesis-that psychology, and the problems it addresses, are likely best approached from multiple levels of analysis. Unlike Tryon, we are not convinced that neural networks and computational neuroscience provide a single template through which all of psychology can be integrated. We are in agreement with Staats that attempts to reduce psychological phenomena to neural events alone are likely to be misleading and unproductive. One important example where such reductionism has been alive and well is addiction, where prominent biomedical models have defined addiction as a "brain disease." Our reply article concludes by arguing that a multilevel approach to psychology is essential in guiding hiring practices, funding agency priorities, and training students.

  4. Classical and Modern Design Solutions in Conceptual Design of a Pedestrian Bridge over Vistula River in Cracow

    Science.gov (United States)

    Ryż, Karol; Pańtak, Marek

    2017-10-01

    In the paper the design concept of the steel pedestrian bridge over Vistula river in Cracow, Poland has been characterised. The footbridge was designed as a truss structure with steel pipes, Warren truss configuration, arched bottom chord and spans 15.5+120.0+15.5 m. Intensive tourist traffic around the Wawel Castle in Cracow, directed towards the historic Kazimierz district, Wawel Hill and the Old Town Market Place requires the creation of a bridge structure over the Vistula River that will meet both the communication and recreation functions. An additional aim was to design a structure which architectural form will not unduly and negatively interfere in the environment and will join the technical capabilities of the XXI century with the charm of nearby historic buildings.

    Three different internal airway stents were studied in an animal model of tracheomalacia: the Palmaz stent (Johnson & Johnson, Warren, New Jersey) and the NIR stent (Medinol Ltd., Tel Aviv, Israel)--both made of stainless steel in the form of tubular mesh--and the Nitinol stent, made of nickel-titanium formed into a spiral shape. All three stents could be adequately stabilized in the malacic tracheal segment. The Nitinol stent (Medinol Ltd., Tel Aviv, Israel) proved to be less reactive to the tracheal mucosa, demonstrated higher biocompatibility with significantly less granulation tissue formation, and showed superior radial resistance. Extraction of the Nitinol stent also proved to be much smoother. This stent may be the stent of choice in the treatment of tracheo- and bronchomalacia.

  6. Ambiguous Authorities: Vertigo and the Auteur Figure

    Directory of Open Access Journals (Sweden)

    Isabelle Licari-Guillaume

    2017-12-01

    Full Text Available This article examines authorial performance in the context of DC’s Vertigo line. In the 1990s, Vertigo gained its reputation as an innovative and progressive imprint by promoting the work of British scriptwriters, who were hailed as true author figures, despite the inherently collaborative nature of the mainstream comics industry. In a manner reminiscent of “auteur theory”, writers such as Neil Gaiman, Warren Ellis or Grant Morrison developed attractive author personas which they consistently displayed through interviews, letter columns or social media, but also, more importantly, by inserting their avatars within the comics they scripted. Upon closer examination, however, it becomes clear that their work in fact simultaneously asserts and destabilizes writerly authority, in a manner that is consistent with Linda Hutcheon’s view of postmodernity. By multiplying author figures and playfully disseminating authority, Vertigo authors question their own authorial control over the text, asserting instead the crucial role played by the reader.

    Full Text Available Lights are essential for humans and other living creatures. Without lights or lighting, surely it will be hard to do everything, especially in the afternoon or at night. As the development of civilization and technology, humans created artificial lighting. For the first time, it was only a substitute for natural light from the sun. Artificial light was provided from the fire; then research and development of the light bulb were conducted by Alessandro Volta, Sir Humphry Davy, Warren De La Rue, to Thomas Alva Edison. After the natural lights from the sun can be replaced by artificial lighting from the lamp, the development of lighting is getting much complex ranging from technical to psychological things. This relates to the increasing human activity in the room. The diversity of different activity requires different types of lighting methods. The development results not only about technical and psychological problems but also aesthetic elements. 

  10. Determination of the stacking fault energies of face centured cubic metals and alloys by X-rays diffraction

    International Nuclear Information System (INIS)

    Borges, J.F.A.; Padilha, A.F.; Imakuma, K.

    1988-03-01

    An X-rays diffraction method was applied to measure the Stacking Fault Energies (SFE) of the AISI 304, AISI 316, AISI 347 and DIN-WERKSTOFF 1.4970 Austenitic Stainless Steels. The SFE determination plays an important role in the research of the mecanichal behaviour of the Metal and Alloys, their deformation mechanisms, stability of micro-structure and electronic configuration. The method is based on the relationship between the SFE and the ratio of the Mean Square Strains to the Stacking-Fault probability. The Mean Square Strain was evaluated by Fourier Analysis of X-rays Diffaction profiles, corrected to reduce instrumental effects, followed by the application of the Warren-Averbach method to the Fourier Coefficients. The Stacking-Fault probabilities were derived from the changes of peak separations between cold-worked and annealed specimens. (author) [pt

    To replicate Sifers, Puddy, Warren, and Roberts (2002) examining reporting rates of demographic, methodological, and ethical information in articles published during 1997, and to compare these rates to those found in articles published during 2005, in order to determine whether and how reporting practices of these variables have changed over time. We examined reporting demographic, methodological, and ethical information in articles in four journals: Journal of Pediatric Psychology, Journal of Clinical Child and Adolescent Psychology, Journal of Abnormal Child Psychology, and Child Development. Reporting rates during 2005 were compared to articles published during 1997. These four journals improved on many of the 23 variables compared to Sifers et al. including increases in the reporting of ethnicity, attrition, child assent procedures, socioeconomic status, reliability, and reward/incentive offered to participants. Improvements in descriptive information have implications for interpretation, replication, and generalizability of research findings.

  12. AN ACTIVE FRACTURE MODEL FOR UNSATURATED FLOW AND TRANSPORT

    International Nuclear Information System (INIS)

    HUI-HAI LIU, GUDMUNDUR S. BODVARSSON AND CHRISTINE DOUGHTY

    1999-01-01

    Fracture/matrix (F/M) interaction is a key factor affecting flow and transport in unsaturated fractured rocks. In classic continuum approaches (Warren and Root, 1963), it is assumed that flow occurs through all the connected fractures and is uniformly distributed over the entire fracture area, which generally gives a relatively large F/M interaction. However, fractures seem to have limited interaction with the surrounding matrix at Yucca Mountain, Nevada, as suggested by geochemical nonequilibrium between the perched water (resulting mainly from fracture flow) and pore water in the rock matrix. Because of the importance of the F/M interaction and related issues, there is a critical need to develop new approaches to accurately consider the interaction reduction inferred from field data at the Yucca Mountain site. Motivated by this consideration, they have developed an active fracture model based on the hypothesis that not all connected fractures actively conduct water in unsaturated fractured rocks

    Ryu, Ho Jin; Kang, Kwon Ho; Moon, Je Sun; Song, Kee Chan; Choi, Yong Nam

    2003-01-01

    The nano-scale crystallite sizes of simulated spent fuel powders were measured by the neutron diffraction line broadening method in order to analyze the sintering behavior of the dry process fuel. The mixed U0 2 and fission product oxide powders were dry-milled in an attritor for 30, 60, and 120 min. The diffraction patterns of the powders were obtained by using the high resolution powder diffractometer in the HANARO research reactor. Diffraction line broadening due to crystallite size was measured using various techniques such as the Stokes' deconvolution, profile fitting methods using Cauchy function, Gaussian function, and Voigt function, and the Warren-Averbach method. The r.m.s. strain, stacking fault, twin and dislocation density were measured using the information from the diffraction pattern. The realistic crystallite size can be obtained after separation of the contribution from the non-uniform strain, stacking fault and twin

    Sorption of radionuclides on mineral surfaces strongly affects their fate and mobility in the geosphere. Therefore using of clay minerals as a barrier In LLW repositories can delay the dispersion of radionuclides into environment. That is of fundamental importance for maintaining environmental quality and for the safety and long-term performance of waste repositories. In this study XRD analysis was applied to investigate three different types of clay minerals for quantitative analysis of each type and the Mud Master program for the measurement of the crystallite thickness distribution (CTD) according to of the BWA (Bertaut-Warren Averbach) technique. Six sample s of the three types of clay (Kaolin, Aswan clay and Ball clay) were studied. XRD and Mud Master were used to investigate the relation between CTD and Cs -137 uptake mechanism onto the clay. It was found that the best adsorption capacity related to the kaolinite content and the lowest CTD

    2016-01-01

    Full Text Available Life-cycle cost (LCC is the much known method used for decision making that considers all costs in the life of a system or equipment. Predicting LCCs is fraught with potential errors, owing to the uncertainty in future events, future costs, interest rates, and even hidden costs. These uncertainties have a direct impact on the decision making. Activity based LCC is used to identify the activities and cost drivers in acquisition, operation and maintenance phase. This activity based LCC is integrated with fuzzy set theory and interval mathematics to model these uncertainties. Day–Stout–Warren (DSW algorithm and the vertex method are then used to evaluate competing alternatives. A case of two pumps (Pump A and Pump B are taken and their LCC is analysed using the developed model. The equivalent annual cost of Pump B is greater than Pump A, which leads the decision maker to choose Pump A over Pump B.

    Using low cost spray pyrolysis technique, polycrystalline CaSO{sub 4} thin films were successfully grown on a glass substrate with a thickness of about 1 μm. Samarium doping has been performed on CaSO{sub 4} thin films to explore luminescence properties. The characterizations of these films were carried out using X-ray diffraction, Scanning Electron Microscopy and optical measurements. The structural analyses reveal the existence of hexagonal CaSO{sub 4} phase with a (200) preferred orientation belonging to CaS compound for substrate temperatures below 350 °C. It is shown that the crystallinity of the sprayed thin films can be improved by increasing substrate temperature up to 250 °C. Warren-Averbach analysis has been applied on X-ray diffractogram to determine structural parameters involving the phase with its amount, the grain size and the lattice parameters using Maud software. The surface topography shows a rough surface covered by densely packed agglomerated clusters having faceted and hexagonal shapes. Energy dispersive microscopy measurements confirm the presence of calcium and sulfur in equal proportions as well as high percentage of oxygen. Photoluminescence at room temperature revealed that luminescence peaks are attributed to the intrinsic emission of pure CaSO{sub 4} phase. - Highlights: • Warren Averbach analysis reveal the presence of hcp structure of CaSO{sub 4} phase. • A mixture of CaSO{sub 4} and CaHO{sub 4.5}S phases has been detected for lower T{sub s}. • For increasing T{sub s}, the CaHO{sub 4.5}S phase has been disappeared. • The origin of PL peaks has been identified.

  17. Temporal Patterns in the Abundance of a Critically Endangered Marsupial Relates to Disturbance by Roads and Agriculture.

    2016-01-01

    The aim of this study was to investigate how landscape disturbance associated with roads, agriculture and forestry influenced temporal patterns in woylie (Bettongia penicillata) abundance before, during and after periods of rapid population change. Data were collected from an area of approximately 140,000 ha of forest within the Upper Warren region in south-western Australia. Woylie abundance was measured using cage trapping at 22 grid and five transect locations with varying degrees of landscape disturbance between 1994 and 2012. We found evidence that the distribution and abundance of woylies over time appears to be related to the degree of fragmentation by roads and proximity to agriculture. Sites furthest from agriculture supported a greater abundance of woylies and had slower rates of population decline. Sites with fewer roads had a greater abundance of woylies generally and a greater rate of increase in abundance after the implementation of invasive predator control. The results of this study suggest that landscape disturbance is less important at peak population densities, but during times of environmental and population change, sites less dissected by roads and agriculture better support woylie populations. This may be due to the role these factors play in increasing the vulnerability of woylies to introduced predators, population fragmentation, weed species invasion, mortality from road collisions or a reduction in available habitat. Strategies that reduce the impact of disturbance on woylie populations could include the rationalisation of forest tracks and consolidation of contiguous habitat through the acquisition of private property. Reducing the impact of disturbance in the Upper Warren region could improve the resilience of this critically important woylie population during future environmental change.

  18. Collective Behavior of Hair, and Ponytail Shape and Dynamics

    Science.gov (United States)

    Ball, Robin

    I will discuss how we can build a mathematical model of the behaviour of a bundle of hair, comparing the results with experimental studies of the shape and dynamics of human ponytails. We treat the individual fibers as elastic filaments with random intrinsic curvature, in which the balance of bending elasticity, gravity, orientational disorder and inertia is recast as a differential equation for the envelope of the fibre bundle. The static elements of this work were first reported in R.E. Goldstein, P.B. Warren and R.C. Ball, Physical Review Letters 108, 078101 (2012). The compressibility of the bundle enters through an ``equation of state'' whose empirical form is shown to arise from a Confined Helix Model, in which the constraint of the surrounding hair is on a given fibre is represented as a confining cylinder. Using this model we find the ponytail shape is well fit with only one adjustable parameter, which is the degree to which the confining cylinders over fill space. The dynamics of driven vertical ponytail motion is well reproduced provided we introduce some damping, and we find the level of damping required is consistent with that arising from viscous drag of the lateral motion of the hair fibres through the interstitial air. Most of our match with experiment is achieved by approximating the fibre density of the ponytail to to be uniform across its cross-section, and to vary only length-wise. However we show that detail near the exit from a confining clamp (aka hairband) is only captured by computing the full cross-sectional variation. The work reported is joint with RE Goldstein (Cambridge UK) and PB Warren (Unilever Research).

    The Externally-Fired Combined Cycle (EFCC) is an attractive emerging technology for powering high efficiency combined gas and steam turbine cycles with coal or other ash bearing fuels. In the EFCC, the heat input to a gas turbine is supplied indirectly through a ceramic air heater. The air heater, along with an atmospheric coal combustor and ancillary equipment, replaces the conventional gas turbine combustor. A steam generator located downstream from the ceramic air heater and steam turbine cycle, along with an exhaust cleanup system, completes the combined cycle. A key element of the EFCC Development Program, the 25 MMBtu/h heat-input Kennebunk Test Facility (KTF), has recently begun operation. The KTF has been operating with natural gas and will begin operating with coal in early 1995. The US Department of Energy selected an EFCC repowering of the Pennsylvania Electric Company`s Warren Station for funding under the Clean Coal Technology Program Round V. The project focuses on repowering an existing 48 MW (gross) steam turbine with an EFCC power island incorporating a 30 MW gas turbine, for a gross power output of 78 MW and a net output of 72 MW. The net plant heat rate will be decreased by approximately 30% to below 9,700 Btu/kWh. Use of a dry scrubber and fabric filter will reduce sulfur dioxide (SO{sub 2}) and particulate emissions to levels under those required by the Clean Air Act Amendments (CAAA) of 1990. Nitrogen oxides (NO{sub x}) emissions are controlled by the use of staged combustion. The demonstration project is currently in the engineering phase, with startup scheduled for 1997. This paper discusses the background of the EFCC, the KTF, the Warren Station EFCC Clean Coal Technology Demonstration Project, the commercial plant concept, and the market potential for the EFCC.

    Most frequent complications in patients with liver cirrhosis are due to portal hypertension. Beside ascites circumvent vessles formate with vasodilatation. Due to counterregulation a secondary hyperaldosteronism develops with release of vasocontrictive agents. If conservative and endoscopic methods fail, indication for building a portosystemic shunt is given. The TIPSS procedure is less invasive than the surgical method of Warren-Shunt, so the radiological intervention has replaced surgery. Reducing the portal pressure by the shunt, the clinical complications change for the better. Still problems are defined as hepatic encephalopathy and right ventricular heart failure. Regular follow up investigations have to be performed to detect complications in the shunt. Using regular clinical and radiological check up TIPSS is of clinical benefit with good long term results. (orig.) [German] Die haeufigsten Komplikationen bei Patienten mit einer Leberzirrhose lassen sich auf das Vorliegen einer portalen Hypertension zurueckfuehren. Neben einer Aszitesbildung kommt es zur Vasodilatation mit Ausbildung portaler Umgehungskreislaeufe, gegenregulatorisch zu einem sekundaeren Hyperaldosteronismus und Ausschuettung vasokonstriktiver Substanzen. Sind mittels konservativer und endoskopischer Methoden die Komplikationen nicht mehr zu beherrschen, ist die Indikation zur Shuntanlage gegeben. Wegen der geringeren Invasivitaet einer TIPSS-Anlage gegenueber der operativen Methode eines Warren-Shunts hat sich die interventionell radiologische Methodik in den letzten Jahren immer mehr durchgesetzt. Durch den mittels Shuntanlage reduzierten Pfortaderdruck kommt es zu einer deutlichen klinischen Besserung der unterschiedlichen Komplikationen. Als klinisch problematische Symptome bei der Shuntanlage sind die hepatische Enzephalopathie und eine Zunahme der Rechtsherzbelastung zu werten. Um Komplikationen im Bereich des Shunts frueh zu erkennen, muss dieser engmaschig kontrolliert werden. Unter

    Full Text Available The Earth’s crust hosts a subsurface, dark, and oligotrophic biosphere that is poorly understood in terms of the energy supporting its biomass production and impact on food webs at the Earth’s surface. Dark oligotrophic volcanic ecosystems (DOVEs are good environments for investigations of life in the absence of sunlight as they are poor in organics, rich in chemical reactants and well known for chemical exchange with Earth’s surface systems. Ice caves near the summit of Mt. Erebus (Antarctica offer DOVEs in a polar alpine environment that is starved in organics and with oxygenated hydrothermal circulation in highly reducing host rock. We surveyed the microbial communities using PCR, cloning, sequencing and analysis of the small subunit (16S ribosomal and Ribulose-1,5-bisphosphate Carboxylase/Oxygenase (RubisCO genes in sediment samples from three different caves, two that are completely dark and one that receives snow-filtered sunlight seasonally. The microbial communities in all three caves are composed primarily of Bacteria and fungi; Archaea were not detected. The bacterial communities from these ice caves display low phylogenetic diversity, but with a remarkable diversity of RubisCO genes including new deeply branching Form I clades, implicating the Calvin-Benson-Bassham cycle as a pathway of CO2 fixation. The microbial communities in one of the dark caves, Warren Cave, which has a remarkably low phylogenetic diversity, were analyzed in more detail to gain a possible perspective on the energetic basis of the microbial ecosystem in the cave. Atmospheric carbon (CO2 and CO, including from volcanic emissions, likely supplies carbon and/or some of the energy requirements of chemoautotrophic microbial communities in Warren Cave and probably other Mt. Erebus ice caves. Our work casts a first glimpse at Mt. Erebus ice caves as natural laboratories for exploring carbon, energy and nutrient sources in the subsurface biosphere and the

    The Horned Toad Formation includes five lithostratigraphic members that record alluvial fan, fluvial, lake margin, and lacustrine deposition within a relatively small basin just south of the active Garlock fault during the late Miocene to early Pliocene. These sediments experienced northwest-southeast contractional deformation during the Pliocene-Pleistocene associated with basement-involved reverse faults. Member Two of the Horned Toad Formation has yielded 24 taxa of fossil mammals, referred to as the Warren Local Fauna, including Cryptotis sp., cf. Scapanus, Hypolagus vetus, Hypolagus edensis,? Spermophilus sp., Prothomomys warrenensis n. gen., n. sp., Perognathus sp., Repomys gustelyi, Postcopemys valensis, Peromyscus sp. A, Peromyscus sp. B, Jacobsomys dailyi n. sp., Borophagus cf.

Prosthennops, Megatylopus sp. cf. M. matthewi, Hemiauchenia vera, Camelidae gen. et. sp. indet., and the antilocaprid cf. Sphenophalos. The majority of fossil localities are confined to a 20 m thick stratigraphic interval within a reversed polarity magnetozone. The fauna demonstrates affinity with other late Hemphillian faunas from California, Nevada, Nebraska, Texas, and Mexico. The Lawlor Tuff, dated elsewhere in California at 4.83 ?? 0.04 Ma and geochemically identified in the Horned Toad Formation, overlies most of the fossil mammal localities. Magnetic polarity data are correlated with Chrons 3n.3r, 3n.3n, and 3n.2r, suggesting an age of approximately 5.0 - 4.6 Ma. These constraints indicate an age for the late Hemphillian Warren Local Fauna of 4.85 - 5.0 Ma. ?? Society of Vertebrate Paleontology November 2011.

    The objectives of the study were to determine what strategy (pursuit or interception) individuals used to pass through an oscillating target and to determine if individuals walked towards where they were looking. Kinematic and gaze behaviour data was collected from seven healthy female participants as they started at one of five different starting positions and walked 7 m towards an oscillating target. The target was a two-dimensional 70 cm aperture made by two-76 cm wide doors and oscillated between two end posts that were 300 cm apart. In order to quantify the objectives, target-heading angles [Fajen BR, Warren WH. Behavioral dynamics of steering, obstacle avoidance, and route selection. J Exp Psychol Hum Percept Perform 2003;29(2):343-62; Fajen BR, Warren WH. Visual guidance of intercepting a moving target on foot. Perception 2004;33:689-715] were calculated. Results showed that the participants used neither an interception nor a pursuit strategy to successfully pass through the moving aperture. The participants steered towards the middle of the pathway prior to passing through the middle of the aperture. A cross correlation between the horizontal gaze locations and the medial/lateral (M/L) location of the participants' center of mass (COM) was performed. The results from the cross correlation show that during the final 2s prior to crossing the aperture, the participants walked where they were looking. The findings from this study suggest that individuals simplify a task by decreasing the perceptual load until the final stages. In this way the final stages of this task were visually driven.

    Full Text Available In December 2014, the Center for Migration Studies of New York (CMS released a paper that provides new estimates of the US unauthorized resident population (Warren 2014. The paper describes the development of a new dataset which has detailed information about unauthorized residents, derived from data collected in the US Census Bureau’s American Community Survey (ACS. The dataset will be useful to scholars, researchers, service-providers, and government officials in crafting, implementing, and evaluating programs that serve noncitizens, including the unauthorized. In addition, the new estimates provide an opportunity to examine the dramatic changes in unauthorized immigration in the past two decades and the assumptions that have shaped US policies and public opinion.The new dataset, recent estimates of the unauthorized (Warren and Warren 2013 and statistics on the noncitizen population from IPUMS-USA (Ruggles et al. 2010 highlight several trends related to the decline in the unauthorized population, particularly from Mexico, and the increasing salience of visa overstays in constituting this population. Some trends defy conventional wisdom and all of them have public policy consequences. In particular, we find that: The unauthorized resident population was about a million lower in 2013 than in 2007.The “Great Recession” was not the principal cause of population decline. Annual arrivals into the unauthorized population increased to more than one million in 2000, then began to drop steadily, and have now reached their lowest levels since the early 1980s.From 2000 to 2012, arrivals from Mexico fell by about 80 percent. Between 2010 and 2013, the total unauthorized population from Mexico declined by eight percent. In 2006, the number of arrivals from Mexico fell below the total number of arrivals from all other countries (combined for the first time.The number who stayed beyond the period authorized by their temporary visas (overstays

    Full Text Available Microstructural size characteristics of a reference sepiolite during grinding in a vibratory cup mill have been studied through X-ray diffraction (XRD line broadening analysis, with Warren- Averbach and Voigt function method in different diffraction directions and through field emission electron microscope (FESEM images and surface area measurements. The second XRD method seem s to be more useful for sepiolite analysis because of the difficulty of the Warren – Averbach to be used ; it provides the general trends for crystallite size and strain evolution along the comminution by vibrating dry- milling of sepiolite. A previous morphological modelling allows the interpretation of FESEM images. The apparent crystallite sizes determined via the X- Ray diffraction are in agreement with measurements of widths of the prevalent pinacoidal and prismatic prevalent faces ( of {110}y {010} forms on FESEM images. The found ranges for FESEM width values in rectangular shaped faces includes the XRD crystallite sizes found for [110] and [010] directions o diffarction. So the observed decreasing of XRD crystallite size trough comminution is in agreement with FESEM micromorphological and surface area measurements.

    Purpose. The purpose of this research was to identify whether a relationship exists between state energy-efficiency policy and innovation in the State of California and to shed light on the impact that energy-efficiency policy can have on supporting statewide economic development goals. Theoretical Framework. The theoretical framework drew from foundations in neoclassical economic theory, technology change theory, and new growth theory. Together these theories formed the basis to describe the impacts caused by the innovations within the market economy. Under this framework, policy-generated innovations are viewed to be translated into efficiency and productivity that propel economic benefits. Methodological Considerations. This study examined various economic indices and efficiency attainment indices affecting four home appliances regulated under Title 20's energy-efficiency standard established by the California Energy Commission, Warren Alquist Act. The multiple regression analysis performed provided an understanding of the relationship between the products regulated, the regulation standard, and the policy as it relates to energy-efficiency regulation. Findings. There is enough evidence to show that strategies embedded in the Warren Alquist Act, Title 20 do drive innovation. Three of the four product categories tested showed statistical significance in the policy standard resulting in an industry efficiency improvement. Conclusively, the consumption of electricity per capita in California has positively diverged over a 35-year period from national trends, even though California had mirrored the nation in income and family size during the same period, the only clear case of divergence is the state's action toward a different energy policy. Conclusions and Recommendations. California's regulations propelled manufacturers to reach higher efficiency levels not otherwise pursued by market forces. The California effort included alliances all working together to make

    Erebus volcano on Ross Island, Antarctica, hosts an active phonolitic lava lake, along with a number of persistently degassing vents in its summit crater. Flank degassing also occurs through ice caves and towers. The longevity of the lake, and its stable convection, have been the subject of numerous studies, including Fourier transform infrared (FTIR) spectroscopy of the lava lake. Two distinct gas compositions were previously identified in the main lava lake plume (Oppenheimer et al., 2009; 2011): a persistent 'conduit' gas with a more oxidised signature, ascribed to degassing through a permeable magma conduit; and a H2O- and SO2- enriched 'lake' composition that increases and decreases cyclically due to shallow degassing of incoming magma batches. During the past decade of annual field seasons on Erebus, gas compositions have been measured through FTIR spectroscopy at multiple sites around Erebus volcano, including flank degassing through an ice cave (Warren Cave). We present measurements from four such vents, and compare their compositions to those emitted from the main lava lake. Summit degassing involves variable proportions of H2O, CO2, CO, SO2, HF, HCl, OCS. Cyclicity is evident in some summit vents, but with signatures indicative of shallower magmatic degassing than that of the lava lake. By contrast, flank degassing at Warren Cave is dominated by H2O, CO2, and CH4. The spatial variability in gas compositions within the summit crater suggests an alternative origin for 'conduit' and 'lake' degassing to previous models that assume permeability in the main conduit. Rather, the two compositions observed in main lake degassing may be a result of decoupled 'conduit' gas and pulses of magma rising through discrete fractures before combining in the lake floor or the main plume. Smaller vents around the crater thus emit isolated 'lake' or 'conduit' compositions while their combined signature is observed in the lava lake. We suggest that this separation between gas

    Full Text Available Numerous pulmonary schistosome egg granulomas were present in mice submitted to partial portal vein ligation (Warren's model. The granulomas were characterized by cellular aggregations formed within alveolar tissue. Main cellular types were macrophages (epithelioid cells, eosinophils, plasma cells and lymphocytes. These cells were supported by scanty fibrous stroma and exhibited close membrane contact points amongst themselves, but without forming specialized adhesion apparatus. When granulomas involved arterial structures, proliferation of cndothelial and smooth muscle cells occurred and fibrosis associated with angiogenesis became more evident. Granulomas formed around mature eggs in the pulmonary alveolar tissue presented approximately the same size and morphology regardless of the time of infection, the latter being 10, 18 and 25 weeks after cercarial exposure. This persistence of morphological appearance suggests that pulmonary granulomas do not undergo immunological modulation, as is the case with the granulomas in the liver and, to a lesser extent, in the intestines. Probably, besides general immunological factors, local (stromal factors play an important role in schistosomal granuloma modulation.Em camundongos submetidos à ligadura parcial da veia porta e infecção pelo Schistosoma mansoni, os granulomas periovulares apareceram em grande número nos pulmões, comprovando a validade do modelo de Warren.

This method is a powerful tool for nanomaterials microstructure characterization. In the present work mechanical alloying of ternary system Cu -2 wt. % Cr -6 wt. % Mo was made between 0.25 and 4 h of milling. By means of modified Warren-Averbach and Williamson-Hall methods the crystallite size, dislocation density, microstrain and average distance between dislocations were estimated. The crystallite size values were corrected by stacking fault presence. It was demonstrated that powders have a high anisotropic strain, which was corrected using the average dislocation contrast factors for fcc structures. Also the influence of milling time and percentage of solute on stacking fault probability and stacking fault energy was determined.

    Networks often possess mesoscale structures, and studying them can yield insights into both structure and function. It is most common to study community structure, but numerous other types of mesoscale structures also exist. In this paper, we examine core-periphery structures based on both density and transport. In such structures, core network components are well-connected both among themselves and to peripheral components, which are not well-connected to anything. We examine core-periphery structures in a wide range of examples of transportation, social, and financial networks-including road networks in large urban areas, a rabbit warren, a dolphin social network, a European interbank network, and a migration network between counties in the United States. We illustrate that a recently developed transport-based notion of node coreness is very useful for characterizing transportation networks. We also generalize this notion to examine core versus peripheral edges, and we show that the resulting diagnostic is also useful for transportation networks. To examine the properties of transportation networks further, we develop a family of generative models of roadlike networks. We illustrate the effect of the dimensionality of the embedding space on transportation networks, and we demonstrate that the correlations between different measures of coreness can be very different for different types of networks.

    Dual networks and chemographic analysis are used to investigate the stability of lizardite and chrysotile in the simplest multisystem that describes serpentinization. Phase diagrams for Mg serpentinites described by MgO-SiO/sub 2/-H/sub 2/O are constructed for systems of five, six and seven phases using dual networks. The seven-phase system brucite, forsterite, lizardite, chrysotile, antigorite, enstatite, and talc describes the serpentinization of Mg peridotites. The chrysotile asbestos deposits of southeastern Quebec occur in serpentinized peridotites of Ordovician ophiolites. The asbestos is localized in veins within blocks of partly serpentinized peridotite bounded by zones containing schistose serpentinite and granitic masses. A simple, rapid microscopic test was designed to obtain semi-quantitative measurements of the bending strength of acicular or fibrous crystals. The instrument was tested on samples of asbestiform tremolite from Baltimore, Maryland, and non-asbestiform tremolite from the Warren Head mine in New Hampshire. The samples ranged in size from 0.3 to 0.8 mm in length and 0.9 to 15 ..mu..m in diameter. The asbestiform tremolite was stronger than the non-asbestiform tremolite at every diameter, with an order of magnitude higher strength at small diameters. This indicates that asbestiform tremolite behaves as a whisker, whereas non-asbestiform tremolite does not.

    The present studied evaluated the in vitro effects of PDT on Leishmania (Leishmania) amazonensis promastigotes. For this examination L. amazonensis promastigotes, stain Josefa, were used and maintained in Warren media supplement with fetal bovine serum at 26°C for 96 hours. A viability curve was accomplished using different concentrations of methylene blue photosensitizer associated to red laser light in order to obtain the most effective interaction to inhibit the parasite's growth. Two pre-irradiation periods, 5 and 30 minutes, were evaluated and the promastigotes were counted by colorimetry. On fluorescence microscopy the autophagic processes and reactive oxygen species were detected. Promastigotes treated with Photodynamic Therapy (PDT) by concentrations of 5 and 0,315ug/mL, presented cellular proliferation inhibition when compared to the control. In the first condition, the cells had structural alterations such as truncated cells, cells with two flagella, bleb formation and cells body deformation, while none of these modifications could be visualized in the control group. When analyzed through fluorescence microscopy, the promastigotes treated were positives for free radicals immediately after light application and also 1 hour after treatment presenting signs of autophagia. PDT on L. (L.) amazonensis is effective causing alterations that can help elucidate the mechanisms of the parasite's death when treated with methilene

The aim of this research is to compare the ability of CAPM and TFMFF in estimating the returns on six types of portfolios which are formed based on firm size and BE/ME. Selected samples are stocks of LQ-45 in period of February 2014, which have passed the selection of firm profits and ROE Warren Buffett criteria. Simple linear regression and Multiple linear regression with t test and F test statistics are used to demonstrate the influence and significance level of each variable. The results showed that TFMFF was more superior than CAPM. Market risk factor consistently affected each portfolio. SMB and HML is not always significantly effect on each portfolio, such as portfolio B/H, only market risk factor has a significant effect. However, the addition of SMB factors and HML factors could increase the coefficient of determination in each formed portfolio.

    Activities in environmental analysis support included assistance to the Morgantown and Pittsburgh Energy Technology Centers (METC and PETC) in reviewing and preparing documents required by the National Environmental Policy Act (NEPA) for several projects selected for the Clean Coal Technology (CCT) Program. A key milestone was the completion for PETC of the final Environmental Impact Statement (EIS) for the Healy Clean Coal Project (HCCP) in Healy, Alaska. This work is notable because it is the first site-specific EIS completed for the CCT Program. Another important activity was the preparation for METC of a draft Environmental Assessment (EA) for the Externally Fired Combined Cycle (EFCC) Project in Warren, Pennsylvania. Also, the final EA was completed for the Gasification Product Improvement Facility (GPIF), a proposed project near Morgantown, West Virginia, which is part of METC's R ampersand D Program. In addition, ORNL staff members published a Technical Memorandum entitled open-quotes Potential Effects of Clean Coal Technologies on Acid Precipitation, Greenhouse Gases, and Solid Waste Disposalclose quotes which documents the findings of three open-quotes white papersclose quotes prepared for DOE/FE

    As part of the coal hydrogasification technology development survey project, overseas surveys were carried out as in the preceding fiscal year. With an emphasis placed on the process materials and resources, and on product utilization technologies, surveys and studies were conducted about the trends of development of coal and natural gas resources, and information was collected on energy-related matters in Indonesia and Australia. The need of hydrogasification technology was investigated from the viewpoint of natural resources. Moreover, Japanese engineers were dispatched to APEC (Asia-Pacific Economic Cooperation Conference) New Energy Seminar, Indonesia. Visits were made for information on the natural gas resources at an LNG base in East Kalimantan, Indonesia; coal gasification, energy, and others at CSIRO (Commonwealth Scientific and Industrial Research Organization), Australia; coal bed and methane resources at Warren Center, University of Sydney, Australia; coal bed and methane resources at the Brisbane office, Mitsubishi Gas Chemical Company, Inc.; and coal resources at coal mines of Idemitsu South Queensland Coal Pty Ltd.

    Though the term "bioethics" was coined in 1970-1, it was immediately after World War II that there emerged the idea that the voluntary consent of human beings was absolutely mandatory for medical interventions to be ethically acceptable. The 1964 Declaration of Helsinki asserted that only an explicit consent could morally and ethically justify research on human beings. In the 1978 "Encyclopedia of Bioethics", the US author Warren T. Reich defined bioethics as the systematic study of human behaviour in the fields of health care and life sciences, and carefully differentiated the epistemological profile of bioethics from that of traditional medical ethics deriving from the Hippocratic Oath. An institutional milestone in the Italian evolution of bioethical knowledge and competence was the foundation of the Italian National Bioethics Committee (NBC), established in 1990. The NBC, which answers to the Council of Ministers, provides methodological support to the Italian Government in the field of bioethical issues, elaborating legislative acts and also furnishing information and consultation for other bodies and associations and for the general public. The activity of the NBC is clearly discernible in its free and user-friendly website. Today, the Internet is often the first repository where individuals and patients look for bioethical information. Given that the quality of this information is extremely variable and not infrequently unreliable, initiatives such as that of the above mentioned NBC website are particularly useful and precious both for health care operators and the entire community.

    The Ohio Partnership for Far East Region Science Teachers (OPFERST) is a three-year project funded by Federal Math Science Partnership Funds through a grant to the Ohio Dept. of Education. OPFERST is a partnership (opferst.ysu.edu) of Youngstown State University science and education faculty, trained facilitators and the county and city science consultants. Every (47) school district in the region signed on and during the first year 32 districts participated. During the first two years, 198 teachers representing Ashtabula, Columbiana, Mahoning and Trumbull Counties, as well as Warren City and Youngstown City schools have participated. The vision of OPFERST is to improve the teaching and learning of the Ohio Science Academic Content Standards. Project goals are: 1) Increase science content knowledge of teachers; 2) Implement effective instructional practices; 3) Improve students performance in science; and 4) Develop professional learning communities which will lead to programmatic changes within districts. Goals one through three are met by modeling inquiry-based methods for teaching science content standards. Goal four is met by ongoing meetings through-out the school year, classroom visits by YSU faculty and fieldtrips to the YSU Campus by classes led by OPFERST teachers. Evaluation of OPFERST includes demographic and classroom practice data, pre- and post-tests of participants, journals, homework and the administration of evaluation instruments with some OPFERST participants' students.

  1. The removal of nitric acid to atmospheric particles during a wintertime field study

    Dasch, Jean Muhlbaier; Cadle, Steven H.

    A field was conducted in Warren, MI, during the 1987/88 winter period to examined the reaction of HNO 3 with particulate salt from road deicing. Samples of gases and particles were collected on a daily basis over a 4-month period. If HNO 3 reacts with particulate salt, particles of sodium nitrate will be formed and gaseous hydrochloric acid will be released. Thus, during the periods of high salt concentrations, one would expect increases in HCl and particulate NO 3- and a decrease in HNO 3. The effect was observed, although the total amount of NaNO 3 formed was not large. The increase in particulate NO 3- did not appear in the large particle mode. Although more than 40% of the salt was present as very large particles (> 8 μm), most of the surface area was associated with small particles. Since the reaction occurred at the particle surface, the NO 3- appeared in the small particle mode. Large-particle nitrate has been observed in association with sea salt and crustal particles and has also been attributed to reactions with HNO 3. These cases will be reconsidered based on the road salt results.

    Relationships among alexithymia, personality disorders, and higher-order psychopathological and interpersonal dimensions were examined in 199 college students and a close relative of each. Alexithymia, the difficulty to express and identify emotions, was measured by the Observer Alexithymia Scale (OAS; [Haviland, M. G., Warren, W. L., & Riggs, M. L. (2000). An observer scale to measure alexithymia. Psychosomatics, 41, 385-392]), which was completed by each student's relative. Each student completed three self-report measures: the Coolidge Axis II Inventory (CATI; [Coolidge, F. L. (2000). Coolidge Axis II Inventory: Manual. Colorado Springs, CO: Author.), the Five Dimensional Personality Test (5DPT; [van Kampen, D. (2009). Personality and psychopathology: A theory-based revision of Eysenck's PEN model. Clinical Practice and Epidemiology in Mental Health, 5, 9-21]), and the Horney-Coolidge Tridimensional Inventory (HCTI; [Coolidge, F. L. (1998). Horney-Coolidge Tridimensional Inventory: Manual. Colorado Springs, CO: Author]). Results indicated that higher levels of alexithymia are associated with personality disorders and their traits, such as schizoid, avoidant, and paranoid. With regard to the issue of the similarity and difference between alexithymia and schizoid personality disorder, there was sufficient evidence across all of the measures to suggest that they are not synonymous entities. Finally, alexithymic traits were associated with concurrent depressive traits even in a non-clinical sample. Copyright © 2013 Elsevier Inc. All rights reserved.

    1999-03-01

    The author who is an expert in clinical psychiatry deals with the problem of modeling human Mind the way physicians implicitly use when their profession renders necessary to intervene to help or even cure patients. If physicists, mathematicians or cognitive science specialists and engineers may propose artificial designs for a mind, psychiatrists and psychologists have developed reliable diagnostic systems for the classification of normal or else psychopathological states. Usually in Psychiatry it is not made any use of an algorithmic approach to describe and characterize psychological processes during cognitive, perceptual, emotional, motivational processes or else anticipatory processes, distinct types of memory, learning processes, etc. Differently from what is mentioned in Neuropsychological literature the author and his group were able to find a significant and consistent relationship between the level of ostensive expression of symptoms and competence in interpretation of information carried by verbal communication during the simulation of social interactions by restrict groups of experimenters. Furthermore it is shown how dendro-dendritic models of neural processing are adequate to represent symbolic processes performed by local operators in the Cortex, as well as the usefulness of models of chemical reactors either batch reactors or else flow plug reactors to represent virtual neural networks capable of clarifying some aspects of cognition and of the structure of the Self. Finally many episodes of the life of the late Warren Sturgis McCulloch are recalled as attribute of gratitude of the author who was his before the last student.

Bacteriol. 86:950-955. 1963.-The characteristics of a sialidase produced by Corynebacterium diphtheriae were studied. The enzyme was partially purified from preparations of diphtheria toxin on a column of Sephadex G-75. By this means the lethal factor of diphtheria toxin was separated, in part, from the sialidase activity. There appeared to be a close immunological relationship between the sialidases of C. diphtheriae and clostridia, since a preparation of diphtheria antitoxin was as effective an inhibitor of diphtheria sialidase as of the sialidase of three species of clostridia. Conversely, antitoxin to clostridia inhibited diphtheria sialidase. Diphtheria antitoxin was essentially inactive toward influenza virus sialidase, and was completely inactive against purified sialidase of Vibrio cholerae. Removal of sialic acid from the proteins in a preparation of diphtheria antitoxin did not alter the inhibitory activity of the antitoxin against diphtheria sialidase. The enzyme operated optimally at pH 5.5 and did not require calcium ions for activity. The substrate specificity of diphtheria sialidase appears to be the same as that of other previously described sialidases.

    The stacking fault energy (SFE) in a set of experimental Ni-Cr-Fe alloys was determined using line profile analysis on synchrotron X-ray diffraction measurements. The methodology used here is supported by the Warren-Averbach calculations and the relationships among the stacking fault probability ({alpha}) and the mean-square microstrain (<{epsilon}{sup 2}{sub L}>). These parameters were obtained experimentally from cold-worked and annealed specimens extracted from the set of studied Ni-alloys. The obtained results show that the SFE in these alloys is strongly influenced by the kind and quantity of addition elements. Different effects due to the action of carbide-forming elements and the solid solution hardening elements on the SFE are discussed here. The simultaneous addition of Nb, Hf, and, Mo, in the studied Ni-Cr-Fe alloys have generated the stronger decreasing of the SFE. The relationships between SFE and the contributions on electronic structure from each element of additions were established.

    An article, The H-Bomb Secret: How We Got It, Why We're Telling It, by Howard Morland was to be published in The Progressive magazine in February, 1979. The government, after learning of the author's and the editors' intention to publish the article and failing to persuade them to voluntarily delete about 20% of the text and all of the diagrams showing how an H-bomb works, requested a court injunction against publication. Acting under the Atomic Energy Act of 1954, US District Court Judge Robert W. Warren granted the government's request on March 26. Events dealing with the case are discussed in this publication. Section 1, Progressive Hydrogen Bomb Case, is discussed under the following: Court Order Blocking Magazine Report; Origins of the Howard Morland Article; Author's Motives, Defense of Publication; and Government Arguments Against Disclosure. Section 2, Access to Atomic Data Since 1939, contains information on need for secrecy during World War II; 1946 Atomic Energy Act and its effects; Soviet A-Bomb and the US H-Bomb; and consequences of 1954 Atomic Energy Act. Section 3, Disputed Need for Atomic Secrecy, contains papers entitled: Lack of Studies on H-Bomb Proliferation; Administration's Position on H-Bombs; and National Security Needs vs Free Press

    A cross-sectional study was carried out in natural wild rabbit (Oryctolagus cuniculus) populations from southern Spain to identify risk factors associated to myxoma virus infection. Blood samples from 619 wild rabbits were collected, and questionnaires which included variables related to host, disease, game management and environment were completed. A logistic regression analysis was conducted to investigate the associations between myxomatosis seropositivity (dependent variable) across 7 hunting estates and an extensive set of explanatory variables obtained from the questionnaires. The prevalence of antibodies against myxomatosis virus was 56.4% (95% CI: 52.5-60.3) and ranged between 21.4% (95% CI: 9.0-33.8) and 70.2% (95% CI: 58.3-82.1) among the different sampling areas. The logistic regression analysis showed that autumn (OR 9.0), high abundance of mosquitoes (OR 8.2), reproductive activity (OR 4.1), warren's insecticide treatment (OR 3.7), rabbit haemorrhagic disease (RHD) seropositivity (OR 2.6), high hunting pressure (OR 6.3) and sheep presence (OR 6.4) were associated with seropositivity to myxomatosis. Based on the results, diverse management measures for myxomatosis control are proposed.

    Full Text Available Background. Evidence is accumulating that circulating tumor cells (CTC out of peripheral blood can serve as prognostic marker not only in metastatic but also in early breast cancer (BC. Various methods are available to detect CTC. Comparisons between the different techniques, however, are rare. Material and Methods. We evaluate two different methods for CTC enrichment and detection in primary BC patients: the FDA-approved CellSearch System (CSS; Veridex, Warren, USA and a manual immunocytochemistry (MICC. The cut-off value for positivity was ≥1 CTC. Results. The two different nonoverlapping patient cohorts evaluated with one or the other method were well balanced regarding common clinical parameters. Before adjuvant CHT 21.1% (416 out of 1972 and 20.6% (247 out of 1198 of the patients were CTC-positive, while after CHT 22.5% (359 out of 1598 and 16.6% (177 out of 1066 of the patients were CTC-positive using CSS or MICC, respectively. CTC positivity rate before CHT was thus similar and not significantly different (P=0.749, while CTC positivity rate immediately after CHT was significantly lower using MICC compared to CSS (P<0.001. Conclusion. Using CSS or MICC for CTC detection, we found comparable prevalence of CTC before but not after adjuvant CHT.

    The annual Astronomy Festival on the National Mall (AFNM) takes place on 11 acres north of the Washington Monument in June (previous AFNM were April and July). AFNM, sponsored by Hofstra University, features optical and radio telescope viewing of the Sun, Moon, planets, stars, clusters, and nebulae; a live large-screen image, a cell phone imaging mount; exhibits; hands-on activities; videos; large outdoor banners and posters; citizen science activities; hand-outs; bookmarks, and teacher information materials. With no tall buildings almost the entire sky is visible and 10th mag. moons of Saturn and the Ring Nebula (9.75 mag.) were easily visible on clear nights. Representatives from some of the nation's foremost scientific and educational institutions presented exciting demonstrations and activities; and answered questions about careers in science, celestial objects, and the latest astronomical discoveries. Local amateur astronomers set up twenty telescopes on the Mall and long lines of 20-30 people waited to look through the telescopes. Visitors met astronaut Dr. John Grunsfeld (Associate Administrator, NASA) and astronomers Dr. Lisse, Dr. Livengood, Dr. Warren, and Dr. Paul Hertz (Director, Astrophysics Division, NASA). Important historical astronomers spoke to the attendees: Caroline Herschel (Lynn King); Tycho Brahe (Dean Howarth); and Johannes Kepler (Jeff Jones). Free telescopes, donated by Celestron, were raffled off.

    Full Text Available Peter J Morgan-Warren, Walter Andreatta, Amit K Patel Department of Ophthalmology, Solihull Hospital, Heart of England NHS Foundation Trust, Birmingham, UK Purpose: Opacification of hydrophilic acrylic intraocular lenses (IOLs is an emerging complication following Descemet stripping automated endothelial keratoplasty (DSAEK. We report six cases and review the current literature.Methods: In this retrospective, noncomparative, observational case series, patients with IOL opacification after previous DSAEK surgery were identified from corneal clinic records. Case notes were reviewed for demographic details, indication for DSAEK, IOL model, incidence of rebubbling, and postoperative course.Results: Six patients developed IOL opacification after DSAEK. All patients had Fuchs’ endothelial dystrophy and had previously received hydrophilic acrylic IOL models. Central anterior IOL opacification was noted in all six cases. Five cases (83% had required rebubbling due to dislocated graft tissue, and one had an early postoperative intraocular pressure (IOP rise. Five cases (83% were managed conservatively, and one case with a failed graft underwent redo DSAEK and IOL exchange.Conclusion: Repeated exposure to intracameral air, raised IOP, and other patient influences may be major etiological factors for IOL opacification after DSAEK. We advise avoiding hydrophilic acrylic IOL models in patients who may require future endothelial keratoplasty. Keywords: IOL, DSAEK, lamellar keratoplasty, endothelial corneal transplantation

  13. Witnessing stressful events induces glutamatergic synapse pathway alterations and gene set enrichment of positive EPSP regulation within the VTA of adult mice: An ontology based approach

    Science.gov (United States)

    Brewer, Jacob S.

    It is well known that exposure to severe stress increases the risk for developing mood disorders. Currently, the neurobiological and genetic mechanisms underlying the functional effects of psychological stress are poorly understood. Presenting a major obstacle to the study of psychological stress is the inability of current animal models of stress to distinguish between physical and psychological stressors. A novel paradigm recently developed by Warren et al., is able to tease apart the effects of physical and psychological stress in adult mice by allowing these mice to "witness," the social defeat of another mouse thus removing confounding variables associated with physical stressors. Using this 'witness' model of stress and RNA-Seq technology, the current study aims to study the genetic effects of psychological stress. After, witnessing the social defeat of another mouse, VTA tissue was extracted, sequenced, and analyzed for differential expression. Since genes often work together in complex networks, a pathway and gene ontology (GO) analysis was performed using data from the differential expression analysis. The pathway and GO analyzes revealed a perturbation of the glutamatergic synapse pathway and an enrichment of positive excitatory post-synaptic potential regulation. This is consistent with the excitatory synapse theory of depression. Together these findings demonstrate a dysregulation of the mesolimbic reward pathway at the gene level as a result of psychological stress potentially contributing to depressive like behaviors.

  14. Thematic and athematic present endings in Balto-Slavic and Indo-European

    2015-09-01

    Full Text Available While the original primary thematic endings were preserved quite well in Balto-Slavic, they were often replaced by the corresponding athematic endings following the thematic vowel *‑e/o‑ in the other Indo-European languages, thus bringing them into line with the secondary endings. Without taking the semantics of the thematic flexion into consideration, Warren Cowgill has forcefully defended the traditional view that apart from the 1st sg. ending *‑ō, the thematic endings were identical with the athematic endings preceded by the thematic vowel *‑e/o‑ in Proto-Indo-European. The main point to be taken into consideration is that the rich and heterogeneous material of Balto-Slavic allows a reconstruction which is on the same level as that of Indo-Iranian and Greek. It confirms the view that our reconstructions have a bias toward the languages on which they are primarily based (Cowgill’s “trusty trio Hittite, Sanskrit, Greek”. The history of linguistic reconstruction shows a gradual shift away from the principal languages.

  15. Handling missing data in transmission disequilibrium test in nuclear families with one affected offspring.

    Directory of Open Access Journals (Sweden)

    Gulhan Bourget

    Full Text Available The Transmission Disequilibrium Test (TDT compares frequencies of transmission of two alleles from heterozygote parents to an affected offspring. This test requires all genotypes to be known from all members of the nuclear families. However, obtaining all genotypes in a study might not be possible for some families, in which case, a data set results in missing genotypes. There are many techniques of handling missing genotypes in parents but only a few in offspring. The robust TDT (rTDT is one of the methods that handles missing genotypes for all members of nuclear families [with one affected offspring]. Even though all family members can be imputed, the rTDT is a conservative test with low power. We propose a new method, Mendelian Inheritance TDT (MITDT-ONE, that controls type I error and has high power. The MITDT-ONE uses Mendelian Inheritance properties, and takes population frequencies of the disease allele and marker allele into account in the rTDT method. One of the advantages of using the MITDT-ONE is that the MITDT-ONE can identify additional significant genes that are not found by the rTDT. We demonstrate the performances of both tests along with Sib-TDT (S-TDT in Monte Carlo simulation studies. Moreover, we apply our method to the type 1 diabetes data from the Warren families in the United Kingdom to identify significant genes that are related to type 1 diabetes.

  16. Quantitative analysis of lattice disorder and crystallite size in organic semiconductor thin films

    Rivnay, Jonathan

    2011-07-07

    The crystallite size and cumulative lattice disorder of three prototypical, high-performing organic semiconducting materials are investigated using a Fourier-transform peak shape analysis routine based on the method of Warren and Averbach (WA). A thorough incorporation of error propagation throughout the multistep analysis and a weighted fitting of Fourier-transformed data to the WA model allows for more accurate results than typically obtained and for determination of confidence bounds. We compare results obtained when assuming two types of column-length distributions, and discuss the benefits of each model in terms of simplicity and accuracy. For strongly disordered materials, the determination of a crystallite size is greatly hindered because disorder dominates the coherence length, not finite size. A simple analysis based on trends of peak widths and Lorentzian components of pseudo-Voigt line shapes as a function of diffraction order is also discussed as an approach to more easily and qualitatively assess the amount and type of disorder present in a sample. While applied directly to organic systems, this methodology is general for the accurate deconvolution of crystalline size and lattice disorder for any material investigated with diffraction techniques. © 2011 American Physical Society.

    2013-05-01

    Full Text Available Fumarolic Ice caves on Antarctica’s Mt. Erebus contain a dark oligotrophic volcanic ecosystem (DOVE and represent a deep biosphere habitat that can provide insight into microbial communities that utilize energy sources other than photosynthesis. The community assembly and role of fungi in these environments remains largely unknown. However, these habitats could be relatively easily contaminated during human visits. Sixty-one species of fungi were identified from soil clone libraries originating from Warren Cave, a DOVE on Mt. Erebus. The species diversity was greater than has been found in the nearby McMurdo Dry Valleys oligotrophic soil. A relatively large proportion of the clones represented Malassezia species (37% of Basidomycota identified. These fungi are associated with skin surfaces of animals and require high lipid content for growth, indicating that contamination may have occurred through the few and episodic human visits in this particular cave. These findings highlight the importance of fungi to DOVE environments as well as their potential use for identifying contamination by humans. The latter offers compelling evidence suggesting more strict management of these valuable research areas.

    2016-12-01

    Full Text Available Actresses are some of the most visible working women. Throughout their history, many actresses have navigated the demands of both a professional career and motherhood. For some, these two roles have been mutually exclusive whereas others have found ways to become working mothers. As part of an unpredictable profession with antisocial hours, a mother employed in the acting profession knows much about the search for the idyllic notion of work/life balance. However, despite this long history of the working mother/actress in the off-stage arena, the opportunity for the actress to inhabit a similar role in her working life onstage is only too rare. In fact, the absence of the stage archetype of the salaried working mother is startling. This article surveys examples of stage representations of working motherhood, considering historical examples including Nora from A Doll’s House, Mrs Warren and Mother Courage. The main focus is on more recent representations of the working mother and debates around C21st motherhood in such plays as Lucinda Coxon’s Happy Now (2008, Amelia Bullmore’s Mammals (2007 and Gina Gionfriddo’s Rapture, Blister, Burn (2014. The aim is to gain a fuller understanding of shifting attitudes towards, and debates around, the figure of the working mother. A figure who, despite her elusive presence onstage, is increasingly prevalent in the profession who embodies her, the audience who consumes her, and the wider socio-political context.

  20. Reduced Fracture Finite Element Model Analysis of an Efficient Two-Scale Hybrid Embedded Fracture Model

    Amir, Sahar Z.

    2017-06-09

    A Hybrid Embedded Fracture (HEF) model was developed to reduce various computational costs while maintaining physical accuracy (Amir and Sun, 2016). HEF splits the computations into fine scale and coarse scale. Fine scale solves analytically for the matrix-fracture flux exchange parameter. Coarse scale solves for the properties of the entire system. In literature, fractures were assumed to be either vertical or horizontal for simplification (Warren and Root, 1963). Matrix-fracture flux exchange parameter was given few equations built on that assumption (Kazemi, 1968; Lemonnier and Bourbiaux, 2010). However, such simplified cases do not apply directly for actual random fracture shapes, directions, orientations …etc. This paper shows that the HEF fine scale analytic solution (Amir and Sun, 2016) generates the flux exchange parameter found in literature for vertical and horizontal fracture cases. For other fracture cases, the flux exchange parameter changes according to the angle, slop, direction, … etc. This conclusion rises from the analysis of both: the Discrete Fracture Network (DFN) and the HEF schemes. The behavior of both schemes is analyzed with exactly similar fracture conditions and the results are shown and discussed. Then, a generalization is illustrated for any slightly compressible single-phase fluid within fractured porous media and its results are discussed.

  1. The Gravity of Giraffe Physiology

    By virtue of its tallness and terrestrial environment, the giraffe is a uniquely sensitive African animal to investigate tissue adaptations to gravitational stress. One decade ago, we studied transcapillary fluid balance and local tissue adaptations to high cardiovascular and musculoskeletal loads in adult and fetal giraffes. Previous studies by Goetz, Pattersson, Van Citters, Warren and their colleagues revealed that arterial pressure near the giraffe heart is about twice that in humans, to provide more normal blood pressure and perfusion to the brain. Another important question is how giraffes avoid pooling of blood and tissue fluid (edema) in dependent tissue of the extremities. As monitored by radiotelemetry, the blood and tissue fluid pressures that govern transcapillary exchange vary greatly with exercise. These pressures, combined with a tight skin layer, move fluid upward against gravity. Other mechanisms that prevent edema include precapillary vasoconstriction and low permeability of capillaries to plasma proteins. Other anatomical adaptations in dependent tissues of giraffes represent developmental adjustments to high and variable gravitational forces. These include vascular wall hypertrophy, thickened capillary basement membrane and other connective tissue adaptations. Our results in giraffe suggest avenues of future gravitational research in other animals including humans.

    In 1956 the Enrico Fermi Presidential Award was established to recognize scientists, engineers, and science policymakers who gave unstintingly over their careers to advance energy science and technology. The first recipient was John von Neumann. .1 Among those scientists who were thought eligible for the award were Hans Bethe, J. Robert Oppenheimer, and Edward Teller. In 1959 Norris Bradbury was asked to comment on the relative merits of each these three men, whom he knew well from their affiliation with Los Alamos. Below is a reproduction of the letter Bradbury sent to Dr. Warren C. Johnson of the AEC’s General Advisory Committee(GAC) containing his evaluation of each man. The letter might surprise those not accustomed to Bradbury’s modus operandi of providing very detailed and forthright answers to the AEC. The letter, itself, was found in cache of old microfilm. Whether because of the age of the microfilm or the quality of the filming process, portions of the letter are not legible. Where empty brackets appear, the word or words could not be read or deduced. Words appearing in brackets are guesses that appear, from the image, to be what was written. These guesses, of course, are just that – guesses.

  3. X-ray diffraction analysis of a severely plastically deformed aluminum alloy

    The crystallite size, lattice microstrain, lattice parameter, and formation of solid solutions of a nanocrystalline Al 93 Fe 3 Cr 2 Ti 2 alloy prepared via mechanical alloying (MA) starting from elemental powders have been investigated using the Rietveld method of X-ray diffraction (XRD) in conjunction with line-broadening analyses through the variance, Warren-Averbach, and Stokes and Wilson methods. Detailed analyses using transmission electron microscopy (TEM), scanning electron microscopy (SEM), and inductively coupled plasma-optical emission spectroscopy (ICP) have also been conducted in order to corroborate the formation of solid solutions and the grain size measurement determined from the XRD analyses. The results from the exhaustive XRD analyses are in excellent agreement with those derived from the investigation of TEM, SEM, and ICP. The lattice microstrains of the nanocrystalline Al solid solution determined from the XRD analyses are isotropic along different crystallographic directions and high, exhibiting the same order of magnitude as the ratio of the tensile strength to the elastic modulus of the Al crystal. Implications resulting from the comparison between the present study and the simplified XRD analyses are discussed

    Magnetic resonance imaging (MRI) is a new and innovative technique that affords anatomic images in multiple planes and that may provide information about tissue characterization. The magnetic resonance images are obtained by placing the patient or the area of interest within a powerful, highly uniform, static magnetic field. Magnetized protons (hydrogen nuclei) within the patient align like small magnets in this field. Radiofrequency pulses are then used to create an oscillating magnetic field perpendicular to the main field. Magnetic resonance images differ from those produced by x-rays: the latter are associated with absorption of x-ray energy while magnetic resonance images are based on proton density and proton relaxation dynamics. Proton characteristics vary according to the tissue under examination and reflect its physical and chemical properties. To resolve issues regarding safety and efficacy, the Warren Grant Magnuson Clinical Center and the Office of Medical Applications of Research of the National Institutes of Health (NIH) convened a consensus conference about MRI Oct 26 through 28, 1987. At the NIH, the Consensus Development Conference brings together investigators in the biomedical sciences, clinical investigators, practicing physicians, and consumer and special interest groups to make a scientific assessment of technologies, including drugs, devices, and procedures, and to seek agreement on their safety and effectiveness

    Four traditionally recognized strandline complexes in the southern basin of glacial Lake Agassiz are the Herman, Norcross, Tintah and Campbell, whose names correspond to towns in west-central Minnesota that lie on a linear transect defined by the Great Northern railroad grade; the active corridor for commerce at the time when Warren Upham was mapping and naming the shorelines of Lake Agassiz (ca.1880-1895). Because shorelines represent static water planes, their extension around the lake margin establishes time-synchronous lake levels. Transitions between shoreline positions represent significant water-level fluctuations. However, geologic ages have never been obtained from sites near the namesake towns in the vicinity of the southern outlet. Here we report the first geologic ages for Lake Agassiz shorelines obtained at field sites along the namesake transect, and evaluate the emerging chronology in light of other paleoclimate records. Our current work from 11 sampling sites has yielded 16 independent ages. These results combined with a growing OSL age data set for Lake Agassiz's southern basin provide robust age constraints for the Herman, Norcross and Campbell strandlines with averages and standard deviations of 14.1 ± 0.3 ka, 13.6 ± 0.2 ka, and 10.5 ± 0.3 ka, respectively.

  6. Microstructural parameters in 8 MeV Electron irradiated Bombyx mori silk fibers by wide-angle X-ray scattering studies (WAXS)

    The present work looks into the microstructural modification in Bombyx mori silk fibers, induced by electron irradiation. The irradiation process was performed in air at room temperature by use of 8 MeV electron accelerators at different doses: 0, 25, 50, 75 and 100 kGy respectively. Irradiation of polymer can be used to crosslink or degrade the desired component or to fixate the polymer morphology. The changes in microstructural parameters in these natural polymer fibers have been studied using wide angle X-ray scattering (WAXS) method. The crystal imperfection parameters such as crystallite size , lattice strain (g in %) and enthalpy (a * ) have been determined by line profile analysis (LPA) using Fourier method of Warren. Exponential, Lognormal and Reinhold functions for the column length distributions have been used for the determination of these parameters. The goodness of the fit and the consistency of these results suggest that the exponential distribution gives much better results, even though lognormal distribution has been widely used to estimate the similar stacking faults in metal oxide compounds.

  7. Active and passive spatial learning in human navigation: acquisition of graph knowledge.

    2015-07-01

    It is known that active exploration of a new environment leads to better spatial learning than does passive visual exposure. We ask whether specific components of active learning differentially contribute to particular forms of spatial knowledge-the exploration-specific learning hypothesis. Previously, we found that idiothetic information during walking is the primary active contributor to metric survey knowledge (Chrastil & Warren, 2013). In this study, we test the contributions of 3 components to topological graph and route knowledge: visual information, idiothetic information, and cognitive decision making. Four groups of participants learned the locations of 8 objects in a virtual hedge maze by (a) walking or (b) watching a video, crossed with (1) either making decisions about their path or (2) being guided through the maze. Route and graph knowledge were assessed by walking in the maze corridors from a starting object to the remembered location of a test object, with frequent detours. Decision making during exploration significantly contributed to subsequent route finding in the walking condition, whereas idiothetic information did not. Participants took novel routes and the metrically shortest routes on the majority of both direct and barrier trials, indicating that labeled graph knowledge-not merely route knowledge-was acquired. We conclude that, consistent with the exploration-specific learning hypothesis, decision making is the primary component of active learning for the acquisition of topological graph knowledge, whereas idiothetic information is the primary component for metric survey knowledge.

  8. Helicobacter pylori-induced premature senescence of extragastric cells may contribute to chronic skin diseases.

    Helicobacter pylori, one of the most frequently observed bacterium in the human intestinal flora, has been widely studied since Marshall and Warren documented a link between the presence of H. pylori in the gastrointestinal tract and gastritis and gastric ulcers. Interestingly, H. pylori has also been found in several other epithelial tissues, including the eyes, ears, nose and skin that may have direct or indirect effects on host physiology and may contribute to extragastric diseases, e.g. chronic skin diseases. More recently, it has been shown that H. pylori cytotoxin CagA expression induces cellular senescence of human gastric nonpolarized epithelial cells that may lead to gastrointestinal disorders and systemic inflammation. Here, we hypothesize that also chronic skin diseases may be promoted by stress-induced premature senescence (SIPS) of skin cells, namely fibroblasts and keratinocytes, stimulated with H. pylori cytotoxins. Future studies involving cell culture models and clinical specimens are needed to verify the involvement of H. pylori in SIPS-based chronic skin diseases.

  9. Analytical X-ray line profile analysis based upon correlated dislocations

    Rao, S.; Houska, C.R.

    1988-01-01

    Recent advances describing X-ray line profiles analytically, in terms of a minimum number of parameters, are related to a theory based upon correlated dislocations. It is shown that a multiple convolution approach, based upon the Warren-Averbach (W-A) analysis, leads to a form that closely approximates the strain coefficient obtained by Krivoglaz, Martynenko and Ryaboshopka. This connection enables one to determine the dislocation density and the ratio of the correlation range parameter to the mean particle size. These two results are obtained most accurately from previous analytical approaches which make use of a statistical least-squares analysis. The W-A Fourier-series approach provides redundant information and does not focus on the critical parameters that relate to dislocation theory. Results so far are limited to b.c.c. materials. Results for cold-worked W, Mo, Nb, Cr and V are compared with highly imperfect sputtered films of Mo. A major difference is relatable to higher correlation of dislocations in cold-worked metals than is found in sputtered films deposited at low temperatures. However, in each case, the dislocation density is high. (orig.)

  10. Suppression of nonlinear frequency-sweeping of resonant interchange modes in a magnetic dipole with applied radio frequency fields

    2003-01-01

    Interchange instabilities excited by energetic electrons trapped by a magnetic dipole nonlinearly saturate and exhibit complex, coherent spectral characteristics and frequency sweeping [H. P. Warren and M. E. Mauel, Phys. Plasmas 2, 4185 (1995)]. When monochromatic radio frequency (rf) fields are applied in the range of 100-1000 MHz, the saturation behavior of the interchange instability changes dramatically. For applied fields of sufficient intensity and pulse-length, coherent interchange fluctuations are suppressed and frequency sweeping is eliminated. When rf fields are switched off, coherent frequency sweeping reappears. Since low frequency interchange instabilities preserve the electron's first and second adiabatic invariants, these observations can be interpreted as resulting from nonlinear resonant wave-particle interactions described within a particle phase-space, (ψ,φ), comprised of the third adiabatic invariant and the azimuthal angle. Self-consistent numerical simulation is used to study (1) the nonlinear development of the instability, (2) the radial mode structure of the interchange instability, and (3) the suppression of frequency sweeping. When the applied rf heating is modeled as an 'rf collisionality', the simulation reproduces frequency sweeping suppression and suggests an explanation for the observations that is consistent with Berk and co-workers [H. L. Berk et al., Phys. Plasmas 6, 3102 (1999)

  11. A Survey of Nanoflare Properties in Active Regions Observed with the Solar Dynamics Observatory

    In this paper, we examine 15 different active regions (ARs) observed with the Solar Dynamics Observatory and analyze their nanoflare properties. We have recently developed a technique that systematically identifies and measures plasma temperature dynamics by computing time lags between light curves. The time lag method tests whether the plasma is maintained at a steady temperature, or if it is dynamic, undergoing heating and cooling cycles. An important aspect of our technique is that it analyzes both observationally distinct coronal loops as well as the much more prevalent diffuse emission between them. We find that the widespread cooling reported previously for NOAA AR 11082 is a generic property of all ARs. The results are consistent with impulsive nanoflare heating followed by slower cooling. Only occasionally, however, is there full cooling from above 7 MK to well below 1 MK. More often, the plasma cools to approximately 1–2 MK before being reheated by another nanoflare. These same 15 ARs were first studied by Warren et al. We find that the degree of cooling is not well correlated with the reported slopes of the emission measure distribution. We also conclude that the Fe xviii emitting plasma that they measured is mostly in a state of cooling. These results support the idea that nanoflares have a distribution of energies and frequencies, with the average delay between successive events on an individual flux tube being comparable to the plasma cooling timescale.

    The fostering of reflective capacity within medical education helps develop critical thinking and clinical reasoning skills and enhances professionalism. Use of reflective narratives to augment reflective practice instruction is well documented. At Warren Alpert Medical School of Brown University (Alpert Med), a narrative medicine curriculum innovation of students' reflective writing (field notes) with individualized feedback from an interdisciplinary faculty team (in pre-clinical years) has been implemented in a Doctoring course to cultivate reflective capacity, empathy, and humanism. Interactive reflective writing (student writer/faculty feedback provider dyad), we propose, can additionally support students with rites of passage at critical educational junctures. At Alpert Med, we have devised a tool to guide faculty in crafting quality feedback, i.e. the Brown Educational Guide to Analysis of Narrative (BEGAN) which includes identifying students' salient quotes, utilizing reflection-inviting questions and close reading, highlighting derived lessons/key concepts, extracting clinical patterns, and providing concrete recommendations as relevant. We provide an example of a student's narrative describing an emotionally powerful and meaningful event - the loss of his first patient - and faculty responses using BEGAN. The provision of quality feedback to students' reflective writing - supported by BEGAN - can facilitate the transformation of student to professional through reflection within medical education.

  13. Repetition priming of face recognition in a serial choice reaction-time task.

    1989-05-01

    Marshall & Walker (1987) found that pictorial stimuli yield visual priming that is disrupted by an unpredictable visual event in the response-stimulus interval. They argue that visual stimuli are represented in memory in the form of distinct visual and object codes. Bruce & Young (1986) propose similar pictorial, structural and semantic codes which mediate the recognition of faces, yet repetition priming results obtained with faces as stimuli (Bruce & Valentine, 1985), and with objects (Warren & Morton, 1982) are quite different from those of Marshall & Walker (1987), in the sense that recognition is facilitated by pictures presented 20 minutes earlier. The experiment reported here used different views of familiar and unfamiliar faces as stimuli in a serial choice reaction-time task and found that, with identical pictures, repetition priming survives and intervening item requiring a response, with both familiar and unfamiliar faces. Furthermore, with familiar faces such priming was present even when the view of the prime was different from the target. The theoretical implications of these results are discussed.

  14. Productivity Analysis of Volume Fractured Vertical Well Model in Tight Oil Reservoirs

    2017-01-01

    Full Text Available This paper presents a semianalytical model to simulate the productivity of a volume fractured vertical well in tight oil reservoirs. In the proposed model, the reservoir is a composite system which contains two regions. The inner region is described as formation with finite conductivity hydraulic fracture network and the flow in fracture is assumed to be linear, while the outer region is simulated by the classical Warren-Root model where radial flow is applied. The transient rate is calculated, and flow patterns and characteristic flowing periods caused by volume fractured vertical well are analyzed. Combining the calculated results with actual production data at the decline stage shows a good fitting performance. Finally, the effects of some sensitive parameters on the type curves are also analyzed extensively. The results demonstrate that the effect of fracture length is more obvious than that of fracture conductivity on improving production in tight oil reservoirs. When the length and conductivity of main fracture are constant, the contribution of stimulated reservoir volume (SRV to the cumulative oil production is not obvious. When the SRV is constant, the length of fracture should also be increased so as to improve the fracture penetration and well production.

  15. The luminosity function of quasars

    Science.gov (United States)

    Pei, Yichuan C.

    1995-01-01

    We propose a new evolutionary model for the optical luminosity function of quasars. Our analytical model is derived from fits to the empirical luminosity function estimated by Hartwick and Schade and Warren, Hewett, and Osmer on the basis of more than 1200 quasars over the range of redshifts 0 approximately less than z approximately less than 4.5. We find that the evolution of quasars over this entire redshift range can be well fitted by a Gaussian distribution, while the shape of the luminosity function can be well fitted by either a double power law or an exponential L(exp 1/4) law. The predicted number counts of quasars, as a function of either apparent magnitude or redshift, are fully consistent with the observed ones. Our model indicates that the evolution of quasars reaches its maximum at z approximately = 2.8 and declines at higher redshifts. An extrapolation of the evolution to z approximately greater than 4.5 implies that quasars may have started their cosmic fireworks at z(sub f) approximately = 5.2-5.5. Forthcoming surveys of quasars at these redshifts will be critical to constrain the epoch of quasar formation. All the results we derived are based on observed quasars and are therefore subject to the bias of obscuration by dust in damped Ly alpha systems. Future surveys of these absorption systems at z approximately greater than 3 will also be important if the formation epoch of quasars is to be known unambiguously.

  16. Lichen ecology of the Scunthorpe heathlands. I. Mineral accumulation

    Seaward, M R.D.

    1973-01-01

    An investigation into the distributional and ecological characteristics of the terricolous lichen flora of the Scunthorpe heathlands is described. The Risby Warren area was especially studied, because there is a noticeable terricolous lichen desert and distinctive zonation of lichen communities, each of which incorporates Peltigera rufescens. Peltigera rufescens appeared to be quite tolerant of air pollution in this region, and occurred in sufficient quantities for periodic sampling; this proved valuable for determination of the sulfur, chromium, copper, iron, lead, manganese, and nickel content of the thalli along a 780 m transect. Frequency assessments, together with these element determinations, revealed sharp qualitative and quantitative improvements in the lichen flora with increasing distance from the pollution sources. The stable lichen pattern, together with the mineral accumulation measurements, was indicative of a pollution dome effect operating to a distance of approximately 3 km. Within 100 to 200 m of this critical distance, lichen material had a pronounced metallic accumulation; the latter was compared with urban and herbarium material. The possible use of lichens for the sampling of ambient environmental conditions is discussed.

  18. Thermodynamics of grain boundary premelting in alloys. II. Atomistic simulation

    Williams, P.L.; Mishin, Y.

    2009-01-01

    We apply the semi-grand-canonical Monte Carlo method with an embedded-atom potential to study grain boundary (GB) premelting in Cu-rich Cu-Ag alloys. The Σ5 GB chosen for this study becomes increasingly disordered near the solidus line while its local chemical composition approaches the liquidus composition at the same temperature. This behavior indicates the formation of a thin layer of the liquid phase in the GB when the grain composition approaches the solidus. The thickness of the liquid layer remains finite and the GB can be overheated/oversaturated to metastable states slightly above the solidus. The premelting behavior found by the simulations is qualitatively consistent with the phase-field model of the same binary system presented in Part I of this work [Mishin Y, Boettinger WJ, Warren JA, McFadden GB. Acta Mater, in press]. Although this agreement is encouraging, we discuss several problems arising when atomistic simulations are compared with phase-field modeling.

    Dating from 1943, the earliest work on artificial neural networks (ANN), when Warren Mc Cullock and Walter Pitts developed a study on the behavior of the biological neuron, with the goal of creating a mathematical model. Some other work was done until after the 80 witnessed an explosion of interest in ANNs, mainly due to advances in technology, especially microelectronics. Because ANNs are able to solve many problems such as approximation, classification, categorization, prediction and others, they have numerous applications in various areas, including nuclear. Nodal method is adopted as a tool for analyzing core parameters such as boron concentration and pin power peaks for pressurized water reactors. However, this method is extremely slow when it is necessary to perform various core evaluations, for example core reloading optimization. To overcome this difficulty, in this paper a model of Multi-layer Perceptron (MLP) artificial neural network type backpropagation will be trained to predict these values. The main objective of this work is the development of Multi-layer Perceptron (MLP) artificial neural network capable to predict, in very short time, with good accuracy, two important parameters used in the core reloading problem - Boron Concentration and Power Peaking Factor. For the training of the neural networks are provided loading patterns and nuclear data used in cycle 19 of Angra 1 nuclear power plant. Three models of networks are constructed using the same input data and providing the following outputs: 1- Boron Concentration and Power Peaking Factor, 2 - Boron Concentration and 3 - Power Peaking Factor.

    (Figure 1) This is an outline of my presentation today. The U. S. Army has a dual interest in the use of robots, namely: 1. As a substitute for or an extension of the soldier in the battlefield, and 2. in the factories that make Army materiel, or - as we call it -the the production base. The Production Base can again be divided into three separate segments, i.e., the Army owned and operated facilities or GOG6s, such as Rock Island and Watervliet arsenals, and not to be overlooked, the depot operations. There the Army manufactures gun tubes and other related parts for artillery weapons and repairs and overhauls them. A second category is the Army owned and contractor operated facilities or GOCOs,such as the ammunition plants, the tank plants at Lima, Ohio and Warren, Michigan and the Stratford Engine Plant in Connecticut where gas turbines for helicopter and the Abrams tank are manufactured. The last category covers the industrial base, that is those factories which are not only operated but also owned by the contractor himself also referred to as COCOs. You can see from this description that the Army is supported by a base which produces a diversified line of products. Therefore, the task of technology development and technology insertion is considerably more complex than what one encounters in the average U. S. Manufacturing organization.

    2008-07-01

    Full Text Available This article explores the theoretical work in articulating the motivations and conditions for account-giving in isiXhosa in relation to image restoration. The account-making process, according to Warren (1989, is like a life in motion in which individual characters are portrayed as moving through their experiences, dealing with some conflict or problem in their lives and at the same time searching for a solution. The narrator discovers at the age of twelve that the person she is referring to as her mother is not her real mother and that her real mother died while giving birth to her. The situation at home deteriorates after the death of her father. Her desperation is further fuelled when her stepmother marries a taxi-driver who sexually abuses her. The narrator then resorts to alcohol and drug abuse to cope with her growing sense of not belonging. The opportunity for changing her life and opening up endless avenues for progress and advancement comes when the narrator passes matric and, through her father’s will, pursues her studies at a tertiary institution. She graduates as a top student and now practices as a medical doctor. This quest to understand the major stresses in each individual’s mind is at the core of this article.

    Given the aging U.S. population, it is imperative that medical students recognize and apply geriatrics principles. To address this need, in 2006, the Warren Alpert Medical School of Brown University integrated geriatrics content into a new medical school curriculum. Preclinical and clinical medical students submitted written reflective journals in response to prompts regarding the geriatrics content of the new medical school curriculum, including their didactic and clinical experiences. An interdisciplinary team used a structured qualitative approach to identify themes, including the recognition and application of geriatrics principles. Thirty medical student journalers submitted 405 journal entries. Themes regarding students' emerging understanding of geriatrics principles included a growing understanding of geriatrics principles, recognition of the importance of psychosocial factors and patient preferences in caring for older adults, recognition of the complexities of treating older adults and application of geriatric principles to clinical situations, and understanding of physicians' roles in managing the care of older adults. Medical student reflective journaling allows medical educators to obtain timely feedback on curricular innovations and helps illuminate the process by which medical students learn to recognize and apply core geriatrics principles. © 2013, Copyright the Authors Journal compilation © 2013, The American Geriatrics Society.

These new technologies aim at improving the quality of assistance offered to patients; thus, they demand from the medical staff more effective measures as far as scientific research, training and expenditure of time and financial resources are concerned. In the past, surgeons have led several medical revolutions, such as the use of antiseptic surgical methods by Semelweiss, the use of anesthesia by Warren, antibiotic therapy, the transplants and the onset of the minimally invasive surgery by Mouret and Perissat. The objective of this article is to present the outreach of this new technology which comprises minimal access, computing, robotics and teletransmission. We have concluded that the new technologies developed in the medical field in the last decades, will offer new options and challenges for the treatment of the surgical patient, leading the scientific knowledge to a new era, the one of the virtual environment.

  4. Preventing transfusion-associated graft-versus-host disease: state of the art

    Full Text Available Loren D Fast Division of Hematology/Oncology, Rhode Island Hospital and Warren Alpert School of Medicine at Brown University, Providence, RI, USA Abstract: The transfer of pathogens and the induction of immune responses are deleterious consequences that can result from the transfusion of blood products. Transfusion-associated graft-versus-host disease (TA-GVHD, the most severe immune consequence, occurs when recipient immune responses are incapable of effectively eliminating donor leukocytes, permitting unabated responses of the donor T lymphocytes. Currently, prevention of TA-GVHD is routinely accomplished by exposing blood products to γ-irradiation in order to prevent donor T cell proliferation. Alternative protocols are being developed to meet the challenges associated with the use of γ-irradiation. Use of pathogen reduction protocols, which interfere with nucleic acid replication by modifying nucleic acids, are increasing. Comparison of pathogen reduction protocols with γ-irradiation have found that both protocols are equally effective in preventing T lymphocyte proliferation and GVHD responses when testing in both in vitro and in vivo models. The potential use of pathogen reduction protocols to treat whole blood prior to separation into its components could provide a cost-effective method for preventing TA-GVHD in the future.

  7. Hydrodynamic relaxations in dissipative particle dynamics

    Science.gov (United States)

    Hansen, J. S.; Greenfield, Michael L.; Dyre, Jeppe C.

    2018-01-01

    This paper studies the dynamics of relaxation phenomena in the standard dissipative particle dynamics (DPD) model [R. D. Groot and P. B. Warren, J. Chem. Phys. 107, 4423 (1997)]. Using fluctuating hydrodynamics as the framework of the investigation, we focus on the collective transverse and longitudinal dynamics. It is shown that classical hydrodynamic theory predicts the transverse dynamics at relatively low temperatures very well when compared to simulation data; however, the theory predictions are, on the same length scale, less accurate for higher temperatures. The agreement with hydrodynamics depends on the definition of the viscosity, and here we find that the transverse dynamics are independent of the dissipative and random shear force contributions to the stress. For high temperatures, the spectrum for the longitudinal dynamics is dominated by the Brillouin peak for large length scales and the relaxation is therefore governed by sound wave propagation and is athermal. This contrasts the results at lower temperatures and small length scale, where the thermal process is clearly present in the spectra. The DPD model, at least qualitatively, re-captures the underlying hydrodynamical mechanisms, and quantitative agreement is excellent at intermediate temperatures for the transverse dynamics.

  8. A study of the local atomic structure in Hg0.80Cd0.20Te using x-ray diffuse scattering

    Quintana, J.P.; Cohen, J.B.

    1993-01-01

    The local atomic arrangements in a commercial n-type wafer of Hg 0.8 Cd 0.2 Te were investigated by measuring the diffuse x-ray scattering in two volumes in reciprocal space. A change in contrast between the two measurements was achieved by making one volume measurement at 12037 eV and a second volume measurement at 12270 eV, i.e., near the Hg L III edge. The difference between these two measurements yielded intensity only due to Hg--Hg, Hg--Te, and Hg--Cd pair interactions. In all three patterns, peak-like features were apparent at the forbidden Bragg peak positions on thermal diffuse scattering ridges that joined major Bragg reflections; these are primarily attributed to second order displacement effects on the mixed cation sublattice. The first two Warren-Cowley short-range order parameters were determined to be α 1/2 1/2 0 =-0.050(26) and α 110 =0.118(35). Simulations of the structure revealed small ordered regions with a preference for 3:1 Hg--Cd near neighbor configurations. The near-neighbor Hg--Te bonds contract from that calculated from the average crystal's lattice parameter, and this Hg--Te distance is less than the distance in HgTe

    2018-01-01

    A term transport phenomena arises as a second paradigm at the end of 1950s with high awareness that there was a strong need to improve the scoping of chemical engineering science. At that point, engineers became highly aware that it is extremely important to take step forward from pure empirical description and the concept of unit operations only to understand the specific process using phenomenological equations that rely on three elementary physical processes: momentum, energy and mass transport. This conceptual evolution of chemical engineering was first presented with a well-known book of R. Byron Bird, Warren E. Stewart and Edwin N. Lightfoot, Transport Phenomena, published in 1960 [1]. What transport phenomena are included in environmental engineering? It is hard to divide those phenomena through different engineering disciplines. The core is the same but the focus changes. Intention of the authors here is to present the transport phenomena that are omnipresent in treatment of various process streams. The focus in this chapter is made on the transport phenomena that permanently occur in mechanical macroprocesses of sedimentation and filtration for separation in solid-liquid particulate systems and on the phenomena of the flow through a fixed and a fluidized bed of particles that are immanent in separation processes in packed columns and in environmental catalysis. The fundamental phenomena for each thermal and equilibrium separation process technology are presented as well. Understanding and mathematical description of underlying transport phenomena result in scoping the separation processes in a way that ChEs should act worldwide.

  10. The British Lower Palaeolithic of the early Middle Pleistocene

    2011-06-01

    The archaeology of Britain during the early Middle Pleistocene (MIS 19-12) is represented by a number of key sites across eastern and southern England. These sites include Pakefield, Happisburgh 1, High Lodge, Warren Hill, Waverley Wood, Boxgrove, Kent's Cavern, and Westbury-sub-Mendip, alongside a 'background scatter' lithic record associated with the principal river systems (Bytham, pre-diversion Thames, and Solent) and raised beaches (Westbourne-Arundel). Hominin behaviour can be characterised in terms of: preferences for temperate or cool temperate climates and open/woodland mosaic habitats (indicated by mammalian fauna, mollusca, insects, and sediments); a biface-dominated material culture characterised by technological diversity, although with accompanying evidence for distinctive core and flake (Pakefield) and flake tool (High Lodge) assemblages; probable direct hunting-based subsistence strategies (with a focus upon large mammal fauna); and generally locally-focused spatial and landscape behaviours (principally indicated by raw material sources data), although with some evidence of dynamic, mobile and structured technological systems. The British data continues to support a 'modified short chronology' to the north of the Alps and the Pyrenees, with highly sporadic evidence for a hominin presence prior to 500-600 ka, although the ages of key assemblages are subject to ongoing debates regarding the chronology of the Bytham river terraces and the early Middle Pleistocene glaciations of East Anglia.

Methods: A retrospective case series was assembled from ADNIV patients in which there was fibrotic encapsulation of a fluocinolone acetonide implant. CAPN5 genotypes and surgical repair techniques were reviewed. Results: Two eyes of two ADNIV patients developed a fibrotic capsule over the fluocinolone acetonide implant. Both patients had Stage IV disease. Patient A had a c.731T > C mutation in the CAPN5 gene and patient B had a c.728G > T mutation. The fibrotic membrane was surgically excised and the implant function was restored. Conclusion: The exuberant fibrotic response in later stages of ADNIV may be resistant to local immunosuppression with steroids. Surgical excision of fibrotic membranes over FA implants can reestablish local steroid delivery in cases of severe proliferative vitreoretinopathy.

    To facilitate interoperability of models in a scalable environment, and provide a relevant virtual environment in which Survivability technologies can be evaluated, the US Army Research Development and Engineering Command (RDECOM) Modeling Architecture for Technology Research and Experimentation (MATREX) Science and Technology Objective (STO) program has initiated the Survivability Thread which will seek to address some of the many technical and programmatic challenges associated with the effort. In coordination with different Thread customers, such as the Survivability branches of various Army labs, a collaborative group has been formed to define the requirements for the simulation environment that would in turn provide them a value-added tool for assessing models and gauge system-level performance relevant to Future Combat Systems (FCS) and the Survivability requirements of other burgeoning programs. An initial set of customer requirements has been generated in coordination with the RDECOM Survivability IPT lead, through the Survivability Technology Area at RDECOM Tank-automotive Research Development and Engineering Center (TARDEC, Warren, MI). The results of this project are aimed at a culminating experiment and demonstration scheduled for September, 2006, which will include a multitude of components from within RDECOM and provide the framework for future experiments to support Survivability research. This paper details the components with which the MATREX Survivability Thread was created and executed, and provides insight into the capabilities currently demanded by the Survivability faculty within RDECOM.

  13. Transcending disciplines: Scientific styles in studies of the brain in mid-twentieth century America.

    2012-06-01

    Much scholarship in the history of cybernetics has focused on the far-reaching cultural dimensions of the movement. What has garnered less attention are efforts by cyberneticians such as Warren McCulloch and Norbert Wiener to transform scientific practice in an array of disciplines in the biomedical sciences, and the complex ways these efforts were received by members of traditional disciplines. In a quest for scientific unity that had a decidedly imperialistic flavour, cyberneticians sought to apply practices common in the exact sciences-mainly theoretical modeling-to problems in disciplines that were traditionally defined by highly empirical practices, such as neurophysiology and neuroanatomy. Their efforts were met with mixed, often critical responses. This paper attempts to make sense of such dynamics by exploring the notion of a scientific style and its usefulness in accounting for the contrasts in scientific practice in brain research and in cybernetics during the 1940s. Focusing on two key institutional contexts of brain research and the role of the Rockefeller and Macy Foundations in directing brain research and cybernetics, the paper argues that the conflicts between these fields were not simply about experiment vs. theory but turned more closely on the questions that defined each area and the language used to elaborate answers.

    Using monte Carlo simulation have been carried out an atomistic description of the structure and ordering processes in the system Cu-Au in a two-dimensional model. The ABV model of the alloy is a system of N atoms A and B, located in rigid lattice with some vacant sites. In the model we assume pair wise interactions between nearest neighbors with constant ordering energy J = 0,03 eV. The dynamics was introduced by means of a vacancy that exchanges of place with any atom of its neighbors. The simulations were carried out in a square lattice with 1024 and 4096 particles, using periodic boundary conditions to avoid border effects. We calculate the first two parameters of short range order of Warren-Cowley as function of the concentration and temperature. It was also studied the probabilities of formation of different atomic clusters that consist of 9 atoms as function of the concentration of the alloy and temperatures in a wide range of values. In some regions of temperature and concentration it was observed compositional and thermal polymorphism

    This project sought to identify and characterize the coupled intrinsic photo-chemo-mechanical degradation mechanisms that determine the reliability and operational lifetimes for CPV technologies. Over a three year period, we have completed a highly successful program which has developed quantitative metrologies and detailed physics-based degradation models, providing new insight into the fundamental reliability physics necessary for improving materials, creating accelerated testing protocols, and producing more accurate lifetime predictions. The tasks for the program were separated into two focus areas shown in the figure below. Focus Area 1, led by Reinhold Dauskardt and Warren Cai with a primary collaboration with David Miller of NREL, studied the degradation mechanisms present in encapsulant materials. Focus Area 2, led by Reinhold Dauskardt and Ryan Brock with a primary collaboration with James Ermer and Peter Hebert of Spectrolab, studied stress development and degradation within internal CPV device interfaces. Each focus area was productive, leading to several publications, including findings on the degradation of silicone encapsulant under terrestrial UV, a model for photodegradation of silicone encapsulant adhesion, quantification and process tuning of antireflective layers on CPV, and discovery of a thermal cycling degradation mechanism present in metal gridline structures.

  16. Using neural networks for prediction of nuclear parameters

    Dating from 1943, the earliest work on artificial neural networks (ANN), when Warren Mc Cullock and Walter Pitts developed a study on the behavior of the biological neuron, with the goal of creating a mathematical model. Some other work was done until after the 80 witnessed an explosion of interest in ANNs, mainly due to advances in technology, especially microelectronics. Because ANNs are able to solve many problems such as approximation, classification, categorization, prediction and others, they have numerous applications in various areas, including nuclear. Nodal method is adopted as a tool for analyzing core parameters such as boron concentration and pin power peaks for pressurized water reactors. However, this method is extremely slow when it is necessary to perform various core evaluations, for example core reloading optimization. To overcome this difficulty, in this paper a model of Multi-layer Perceptron (MLP) artificial neural network type backpropagation will be trained to predict these values. The main objective of this work is the development of Multi-layer Perceptron (MLP) artificial neural network capable to predict, in very short time, with good accuracy, two important parameters used in the core reloading problem - Boron Concentration and Power Peaking Factor. For the training of the neural networks are provided loading patterns and nuclear data used in cycle 19 of Angra 1 nuclear power plant. Three models of networks are constructed using the same input data and providing the following outputs: 1- Boron Concentration and Power Peaking Factor, 2 - Boron Concentration and 3 - Power Peaking Factor.

    Maddocks, M. C. D.

    This report differs from most BBC Research Department reports in that it does not contain details of a specific project undertaken at Kingswood Warren. While there has been a continuing development of aspects of digital modulation systems by BBC research engineers over many years, the purpose of this report is to be tutorial. That is, digital transmission techniques need to be explained in a general way if full advantage is to be obtained from other reports concerning digital broadcasting transmission systems. There are, however, references to other specialized publications if particular details are required. The text of this report is based on a paper which was prepared for an Institution of Electrical Engineers' vacation school on new broadcast standards and systems. It discusses, at a general level, the various issues and trade-offs that must be considered in the design of a digital modulation system for broadcast use. It particularly concentrates on giving a simple description of the use and benefits of OFDM systems. The particular issues can be applied to various future broadcast systems which are under development at the BBC and as part of collaborative work in international projects.

      The conclusion of this research is that the concept of leadership education of Thariq as-Suwaidan is the concept of leadership education that having the characteristic of tarbawi, tadribi, waqi‘iy, uswati and Islami. In the sense of the formation of a leader must be through education, training, reality, model, and Islamic. Thariq as-Suwaidan’s Leadership Concept is to strengthen Warren Blank’s theory by the name of “108 Skills of Natural Born Leaders”, the theory that there is no natural leader. Leadership is a collection of traits and skills that can be learned. Application of Thariq as-Suwaidan Leadership Education Concept in Indonesia is under the name of “Youth Leadership Education & Training Program 30 Hours”. The application of Islamic leadership education of Thariq as-Suwaidan is a leadership and leadership training program provided to the youngest of the most fertile human resources, step by step, in a training institute or course established specifically for this purpose, using various varied learning methods. The kind of education has really happened and will constantly happen in the reality of Indonesian society. The condition strictly shows the importance of the roles of Islamic scholars (ulama in Islamic schools or Islamic institutions to perform and to shape their next generation to become the future leaders.

    Full Text Available This paper aims to revisit three adaptations of Red Riding Hood fairy tales and explore some of the wolf’s reincarnations in order to see how realities change in time. It has generally been observed in the literature that in pop culture Red has undergone quite dramatic changes from the little ingénue to the mature seductress. But what has happened to the bad wolf? How is he imagined by the 21st century pop culture? How do his agency and power change? What (new message does he convey? To answer these questions, I shall look at three fairly recent advertisements that adapt the classic Little Red story for the screen: “Red Bull” energizer (February 2010, “Chanel no. 5” (featuring actress Estella Warren, late 1990s, 2007 and “B.U. Heartbeat” (featuring Tyson Kuteyi, 2008 perfumes. I will explore not only how such commercials reframe the dominant Western cultural pattern, but if they also undo the lessons both men and women have so far been forced to learn.

    This compendium contains papers presented at the W. E. Henry Symposium, The Importance of Magnetism in Physics and Material Science. The one-day symposium was conducted to recognize the achievements of Dr. Warren Elliot Henry as educator, scientist, and inventor in a career spanning almost 70 years. Dr. Henry, who is 88 years old, attended the symposium. Nobel Laureate, Dr. Glenn Seaborg, a friend and colleague for over 40 years, attended the event and shared his personal reminiscences. Dr. Seaborg is Associate Director-At-Large at the Lawrence Berkeley National Laboratory. The Compendium begins with three papers which demonstrate the ongoing importance of magnetism in physics and material science. Other contributions cover the highlights of Dr. Henry`s career as a researcher, educator, and inventor. Colleagues and former students share insights on the impact of Dr. Henry`s research in the field of magnetism, low temperature physics, and solid state physics; his influence on students as an educator; and his character, intellect and ingenuity, and passion for learning and teaching. They share a glimpse of the environment and times that molded him as a man, and the circumstances under which he made his great achievements despite the many challenges he faced.

  2. Justice blocks and predictability of U.S. Supreme Court votes.

    Directory of Open Access Journals (Sweden)

    Roger Guimerà

    Full Text Available Successful attempts to predict judges' votes shed light into how legal decisions are made and, ultimately, into the behavior and evolution of the judiciary. Here, we investigate to what extent it is possible to make predictions of a justice's vote based on the other justices' votes in the same case. For our predictions, we use models and methods that have been developed to uncover hidden associations between actors in complex social networks. We show that these methods are more accurate at predicting justice's votes than forecasts made by legal experts and by algorithms that take into consideration the content of the cases. We argue that, within our framework, high predictability is a quantitative proxy for stable justice (and case blocks, which probably reflect stable a priori attitudes toward the law. We find that U.S. Supreme Court justice votes are more predictable than one would expect from an ideal court composed of perfectly independent justices. Deviations from ideal behavior are most apparent in divided 5-4 decisions, where justice blocks seem to be most stable. Moreover, we find evidence that justice predictability decreased during the 50-year period spanning from the Warren Court to the Rehnquist Court, and that aggregate court predictability has been significantly lower during Democratic presidencies. More broadly, our results show that it is possible to use methods developed for the analysis of complex social networks to quantitatively investigate historical questions related to political decision-making.

  3. Si Wire-Array Solar Cells

    2010-03-01

    Micron-scale Si wire arrays are three-dimensional photovoltaic absorbers that enable orthogonalization of light absorption and carrier collection and hence allow for the utilization of relatively impure Si in efficient solar cell designs. The wire arrays are grown by a vapor-liquid-solid-catalyzed process on a crystalline (111) Si wafer lithographically patterned with an array of metal catalyst particles. Following growth, such arrays can be embedded in polymethyldisiloxane (PDMS) and then peeled from the template growth substrate. The result is an unusual photovoltaic material: a flexible, bendable, wafer-thickness crystalline Si absorber. In this paper I will describe: 1. the growth of high-quality Si wires with controllable doping and the evaluation of their photovoltaic energy-conversion performance using a test electrolyte that forms a rectifying conformal semiconductor-liquid contact 2. the observation of enhanced absorption in wire arrays exceeding the conventional light trapping limits for planar Si cells of equivalent material thickness and 3. single-wire and large-area solid-state Si wire-array solar cell results obtained to date with directions for future cell designs based on optical and device physics.

  4. Respiratory and ocular symptoms among employees of a hotel indoor waterpark resort--Ohio, 2007.

    Science.gov (United States)

    2009-02-06

    During January--March 2007, the Warren County Combined Health District (WCCHD) received 665 reports of respiratory and eye irritation from patrons and lifeguards at a hotel indoor waterpark resort in Ohio. Tests revealed normal water chemistry and air chlorine concentrations, and exposure to airborne trichloramine in the waterpark was suspected as the cause of the symptoms. Because of the number of symptom reports and WCCHD's limited ability to measure trichloramine, the district requested an investigation by CDC's National Institute for Occupational Safety and Health (NIOSH). This report describes the results of that investigation, which revealed that trichloramine concentrations in the waterpark ranged from below the limit of detection to 1.06 mg/m3, and some concentrations were at levels that have been reported to cause irritation symptoms (>/=0.5 mg/m3). Lifeguards reported significantly more work-related symptoms (e.g., cough, wheezing, shortness of breath, chest tightness, and eye irritation) than unexposed hotel employees. Lifeguards also reported significantly more eye irritation and cough on days when hotel occupancy was high versus low. Insufficient air movement and distribution likely led to accumulation of trichloramine and exacerbation of symptoms. Based on recommendations to increase air movement and distribution at pool deck level, hotel management modified the ventilation system extensively, and subsequently no new cases were reported to WCCHD. The results of this investigation emphasize the importance of appropriate design and monitoring of ventilation and water systems in preventing illness in indoor waterparks.

Radiotherapy has a long history in the treatment of NMSC. Shortly after the discovery of X-rays and 226Radium, physicians cured patients with NMSC using these new treatments. Both X-ray therapy and brachytherapy have evolved over the years, ultimately delivering higher cure rates and lower toxicity. Electronic brachytherapy for NMSC is based on the technical and clinical data obtained from radionuclide skin surface brachytherapy and the small skin surface applicators developed over the past 25 years. The purpose of this review is to introduce electronic brachytherapy in the context of the history, data, and utilization of traditional radiotherapy and brachytherapy.

    Full text: The classification of the microstructure of nanostructured materials and its relation to macroscopic properties is essential for the development and application of nanomaterials. X-ray line profile analysis is a nondestructive method yielding a series of interesting microstructural parameters: the Bragg reflection of an ideal crystal is a narrow delta-function liKEX peak. Distortions of the regular crystal lattice as well as a finite size of the coherently scattering domains lead to a significant broadening of the peak. By using physical models describing the individual types of broadening it is possible to relate the broadening of the peak to the microstructure of the material. The most successful applications to date assume mainly size and strain broadening. From these models various techniques have been developed to evaluate the same physical quantities via individual methods. Among these methods are the Williamson-Hall and Warren Averbach methods, their so called 'modified' variants and multiple-whole-profile-fitting/modeling. A number of typical problems arising during data preparation and evaluation are presented and a procedure to optimize the processing of the experimental data is given. Refs. 9 (author)

    The surface residual stress behaviour during fatigue of the quenched and tempered medium strength low-alloyed steel SS 2244-05, equivalent to AISI 4140, has been investigated. Notched specimens of shot peened and ground surface conditions were used. The residual stresses were measured by the X-ray diffraction sin/sup 2/psi-method at intervals in the fatigue tests. Fatigue testing was performed with constant load amplitude at nominal pull-push and pull-pull cycling. The effects of peak-load and variable amplitude were also examined. It was found that the residual stress relaxation could be linked to a total mean stress relaxation towards zero, to an extent which is ruled by a softening criteria. Fatigue test data of the shot peened and ground surface conditions are also given. An X-ray diffraction line broadening analysis was undertaken to examine the microstructural behaviour due to fatigue loading and its correlation to the residual stress behaviour. Single-peak analysis with a Voigt-function method was used to estimate the microstructural parameters, domain size and microstrain. Multiple-peak analysis according to the Warren-Averbach method was used to verify the single-peak analysis. The dislocation density was found to decrease depending on the load amplitude, while the dislocation arrangement follows a pattern depending on yield history.

    Full Text Available A lo largo de la historia, la mujer ha sido, entre otras muchas cosas, creadora de conocimientos, productora de materia y guardiana de la biodiversidad. Los rasgos androcéntricos han ido transformando la cultura hasta desembocar en una crisis ecológica, razón de más por la cual se aborda la cuestión medioambiental desde el lado femenino (resaltando los valores de la naturaleza, la mujer, el animal, el sentimiento, la materia y el cuerpo. Fue Françoise d’Eaubonne la primera que usó el término “ecofeminismo” reclamando el cuerpo femenino como propiedad de una misma. Y a partir de esta premisa, diversos grupos de mujeres comenzaron a tomar conciencia sobre los riesgos de su salud, derivados del uso de pesticidas, fertilizantes y excesiva medicalización que repercuten sobre el cuerpo femenino. Y ya Karen Warren hace ecofeminismo desde la filosofía, concibe la diferenciación como inferioridad. La dominación es la peor de las formas de maltrato, y el medioambiente sufre cada día las consecuencias, cierta reflexión habría de impulsar una compasión especial por ese otro que nunca protesta.

  9. Graphene oxide based contacts as probes of biomedical signals

    We have developed a series of graphene oxide (GOx) on polymer contacts and have demonstrated these to be useful for collection of standard biomedically relevant signals, such as electrocardiogram (ECG). The process is wet solution-based and allows for control and tuning of the basic physical parameters of GOx, such as electrical and optical properties, simply by choosing the number of GOx layers. Our GOx characterization measurements show spectral (FTIR, XPS, IR absorbance) features most relevant to such performance, and point towards the likely explanations about the mechanisms for controlling the physical properties relevant for the contact performance. Structural (X-ray topography) and surface characterization (AFM, SEM) indicates to what degree these contacts can be considered homogeneous and therefore provide information on yield and repeatability. We compare the ECG signals recorded by standard commercial probes (Ag/AgCl) and GOx probes, displaying minor differences the solution to which may lead to a whole new way we perform ECG data collection, including wearable electronics and IoT friendly ECG monitoring.

    The purpose of the Lunar Sample Compendium will be to inform scientists, astronauts and the public about the various lunar samples that have been returned from the Moon. This Compendium will be organized rock by rock in the manor of a catalog, but will not be as comprehensive, nor as complete, as the various lunar sample catalogs that are available. Likewise, this Compendium will not duplicate the various excellent books and reviews on the subject of lunar samples (Cadogen 1981, Heiken et al. 1991, Papike et al. 1998, Warren 2003, Eugster 2003). However, it is thought that an online Compendium, such as this, will prove useful to scientists proposing to study individual lunar samples and should help provide backup information for lunar sample displays. This Compendium will allow easy access to the scientific literature by briefly summarizing the significant findings of each rock along with the documentation of where the detailed scientific data are to be found. In general, discussion and interpretation of the results is left to the formal reviews found in the scientific literature. An advantage of this Compendium will be that it can be updated, expanded and corrected as need be.

    Warren (1897) described the genus Oospila for Phorodesma trilunaria Guenée, 1857 from Brazil. Prout (1912; 1932-1933) revised the genus, listing 48 species in the first publication and 58 species in the latter one, in Oospila. Cook and Scoble (1995) grouped eight related genera under Oospila, including 73 species and dividing these into 13 species groups. Pitkin (1996) relied on this revision while publishing a monographic review of the Neotropical geometrine genera. Parsons et al. (1999) attributed the same species that in Cook and Scoble (1995) to the genus. Two species are described later (Viidalepp, 2002; Lévèque & Viidalepp, 2015). While revising collections from the Neotropical region during the last decade, the authors of the present article have found several undescribed taxa: cryptic species are frequently overlooked in large-scale works (Vodă et al., 2014). The result of one case study is published in this article. The primary and subsequent descriptions of relevant taxa are consulted.

  12. Role of substrate aspect ratio on the robustness of capillary alignment

    Capillary forces associated with liquid bridges formed across solid substrates are routinely exploited to align and assemble micro- and nanoscale devices. The magnitude of these forces plays a critical role in minimizing substrate misalignment and therefore should be controlled for robust and reliable fabrication process. We explore through simulations and experiments the role of the substrate aspect ratio (L/W) on capillary restoring forces and torques. Simulations show that increasing the aspect ratio of the substrates increases the capillary torques and forces when the substrates are misaligned through either lateral or rotational perturbations. The effect of substrate area, perimeter, and liquid volume are also systematically explored to show that the increase in restoring torque is caused by an increase in aspect ratio. A simple theoretical model based on the geometry of the system shows excellent agreement with Surface Evolver simulations. Finally, parameters from experimental flip-chip devices [Josell, D. Wallace, W.E. Warren, J.A. Wheeler, D. Powell, A.C. J. Electron. Packag. 124, 227, (2002)] are used in our simulations to show how current capillary self-alignment schemes could benefit from using rectangular substrate shapes with aspect ratio greater than one

    A total of 3960 hens (half ISA Warren and half Dekalb White) were housed in 18 compartments with 220 hens each. The effect of replacing dietary vitamin E by sage on productivity, meat yield and oxidative stability of sausages was studied. One third of all animals received either a vitamin E deficient diet (negative control) or diets supplemented with 30 mg/kg α-tocopherylacetate (positive control) or 25 g sage leaves/kg. At slaughter, meat yield was assessed and sausages were produced (n = 12 per treatment). The omission of vitamin E did not impair the oxidative stability of the raw sausage material or the spiced sausages in comparison to the positive control. Sage supplementation improved oxidative stability after 7 m of frozen storage, but not after 1, 4 and 10 m. Spice addition during meat processing had an antioxidant effect regardless of dietary treatment. Diet supplementation of any type did not affect laying performance and sausage meat yield. Feeding antioxidants to spent hens seemed to be not as efficient as in growing chickens, while seasoning with spices during sausage production proved to be a feasible way to delay lipid oxidation.

    Full Text Available Variation in microstructural features of 2024 aluminum alloy plastically deformed by equal channel angular pressing (ECAP at room temperature, was investigated by X-Ray diffraction in this work. These include dislocation density dislocation characteristic and the cell size of crystalline domains. Dislocations contrast factor was calculated using elastic constants of the alloy such as C 11, C 22 and C 44 . The effect of dislocations contrast factor on the anisotropic strain broadening of diffraction profiles was considered for measuring the microstructural features on the base of the modified Williamson-Hall and Warren-Averbach methods. Results showed that the dislocations density of the solution annealed sample increased from 4.28×10 12m-2 to 2.41×10 14m-2 after one pass of cold ECAP and the fraction of edge dislocations in the solution annealed sample increased from 43% to 74% after deformation. This means that deformation changed the overall dislocations characteristic more to edge dislocations. Also the crystalline cell size of the solution annealed sample decreased from 0.83μm to about 210nm after one pass of ECAP process at room temperature

    Wrap-up effects in reading have traditionally been thought to reflect increased processing associated with intra- and inter-clause integration (Just, M. A. & Carpenter, P. A. (1980). A theory of reading: From eye fixations to comprehension. Psychological Review,87(4), 329-354; Rayner, K., Kambe, G., & Duffy, S. A. (2000). The effect of clause wrap-up on eye movements during reading. The Quarterly Journal of Experimental Psychology,53A(4), 1061-1080; cf. Hirotani, M., Frazier, L., & Rayner, K. (2006). Punctuation and intonation effects on clause and sentence wrap-up: Evidence from eye movements. Journal of Memory and Language,54, 425-443). We report an eye-tracking experiment with a strong manipulation of integrative complexity at a critical word that was either sentence-final, ended a comma-marked clause, or was not comma-marked. Although both complexity and punctuation had reliable effects, they did not interact in any eye-movement measure. These results as well as simulations using the E-Z Reader model of eye-movement control (Reichle, E. D., Warren, T., & McConnell, K. (2009). Using E-Z Reader to model the effects of higher-level language processing on eye movements during reading. Psychonomic Bulletin & Review,16(1), 1-20) suggest that traditional accounts of clause wrap-up are incomplete.

    O presente estudo tem como objetivo mapear as principais colaborações do pensamento social brasileiro acerca da luta organizada do negro ao longo da Primeira República, momento em que o povo negro se viu liberto da antiga sociedade de castas que o escravizava, mas no entanto estava fora do projeto da nova sociedade de classe que se formava. Daremos destaque à densa e original interpretação proposta por Florestan Fernandes em seu A integração do negro na sociedade de classes, elencando os principais fatores que diferenciam essa obra de todo o que já havia sido escrito sobre o negro até aquela época. Procuraremos demonstrar que não constitui exagero colocar o trabalho de Florestan entre os primeiros estudos de caráter pós-colonial sobre a luta pela emancipação do negro brasileiro, uma vez que desenvolve suas análises a partir da dimensão simbólica e psicossocial revelada pelo discurso dos próprios sujeitos do movimento, metodologia que ainda estava em desenvolvimento pela nascente Teoria dos Novos Movimentos Sociais. Para tanto, nos guiaremos pelos trabalhos de analistas como Octavio Ianni (2004, Jessé Sousa (2000, Sérgio Tavolaro (2005 e Ilse Scherer-Warren (2010.

    In comics, "gutters" are the empty spaces between panels that readers must navigate to weave disjointed visual sequences into coherent narratives. A gutter, however, is more than a blank space--it represents a creative zone for making connections and for constructing meaning from disparate ideas, values, and experiences. Over the course of medical training, learners encounter various "gutters" created by the disconnected subject blocks and learning experiences within the curriculum, the ambiguity and uncertainty of medical practice, and the conflicts and tensions within clinical encounters. Navigating these gutters requires not only medical knowledge and skills but also creativity, defined as the ability to make connections between disparate fragments to create meaningful, new configurations. To cultivate medical students' creative capacity, the authors developed the Integrated Clinical Arts (ICA) program, a required component of the first-year curriculum at the Warren Alpert Medical School of Brown University. ICA workshops are designed to place students in a metaphorical gutter, wherein they can practice making connections between medicine and arts-based disciplines. By playing in the gutter, students have opportunities to broaden their perspectives, gain new insights into both medical practice and themselves, and explore different ways of making meaning. Student feedback on the ICA program highlights an important role for creativity and the arts in medicine: to transform gutters from potential learning barriers into opportunities for discovery, self-reflection, and personal growth.

  18. Reduced Fracture Finite Element Model Analysis of an Efficient Two-Scale Hybrid Embedded Fracture Model

    Amir, Sahar Z.; Chen, Huangxin; Sun, Shuyu

    2017-01-01

    A Hybrid Embedded Fracture (HEF) model was developed to reduce various computational costs while maintaining physical accuracy (Amir and Sun, 2016). HEF splits the computations into fine scale and coarse scale. Fine scale solves analytically for the matrix-fracture flux exchange parameter. Coarse scale solves for the properties of the entire system. In literature, fractures were assumed to be either vertical or horizontal for simplification (Warren and Root, 1963). Matrix-fracture flux exchange parameter was given few equations built on that assumption (Kazemi, 1968; Lemonnier and Bourbiaux, 2010). However, such simplified cases do not apply directly for actual random fracture shapes, directions, orientations …etc. This paper shows that the HEF fine scale analytic solution (Amir and Sun, 2016) generates the flux exchange parameter found in literature for vertical and horizontal fracture cases. For other fracture cases, the flux exchange parameter changes according to the angle, slop, direction, … etc. This conclusion rises from the analysis of both: the Discrete Fracture Network (DFN) and the HEF schemes. The behavior of both schemes is analyzed with exactly similar fracture conditions and the results are shown and discussed. Then, a generalization is illustrated for any slightly compressible single-phase fluid within fractured porous media and its results are discussed.

    2013-01-01

    After the economic meltdown of 2008, Warren Buffett famously warned, “beware of geeks bearing formulas.” But as James Weatherall demonstrates, not all geeks are created equal. While many of the mathematicians and software engineers on Wall Street failed when their abstractions turned ugly in practice, a special breed of physicists has a much deeper history of revolutionizing finance. Taking us from fin-de-siècle Paris to Rat Pack-era Las Vegas, from wartime government labs to Yippie communes on the Pacific coast, Weatherall shows how physicists successfully brought their science to bear on some of the thorniest problems in economics, from options pricing to bubbles. The crisis was partly a failure of mathematical modeling. But even more, it was a failure of some very sophisticated financial institutions to think like physicists. Models—whether in science or finance—have limitations; they break down under certain conditions. And in 2008, sophisticated models fell into the hands of people who didn’t...

  1. Laboratory tests, experimental oil spills, models, and reality: The Braer oil spill

    1993-01-01

    The IKU Petroleum Research organization in Norway has accumulated data on the weathering behavior of spilled oils and petroleum products, mainly pertaining to North Sea crudes. Recent weathering research at IKU has been carried out in an elliptical mesoscale flume and in field tests consisting of experimental releases of crude oil. Results of these tests provided information on oil spill dispersion, evaporation, and emulsification. When the tanker Braer grounded in the Shetland Islands in January 1993 in extreme environmental conditions, the imminent release of a load of 84,000 tonnes of North Sea oil confronted response personnel with a variety of issues including the use of dispersants as a response action. Relevant information on the expected behavior of the crude was obtained within a day of the grounding as a result of close relations between IKU and Warren Spring Laboratory. The question is raised whether such information, which could have been spread between several organizations around the world, will be rapidly accessible in the event of another major spill. It is proposed to establish an electronically accessible database on the behavior and fate of specific oils and petroleum products to address this problem. 9 refs., 4 figs

    2006-06-01

    Full Text Available Both Winston S. Churchill (1874-1965 and Franklin D. Roosevelt (1 882-1945 were masters of the English language and effective orators, rallying their people through word and deed to fight as allies against the dictatorial powers during the Second World War. Their public speeches and interviews are replete with proverbs, proverbial expressions, and other phraseologisms. This is also true for their private and secretive letters, messages, memoranda, and telegrams, as can be seen from the materials that Warren F. Kimball edited in the three volumes of Churchill & Roosevelt: The Complete Correspondence (Princeton, NJ: Princeton University Press, 1984. The proverbial language, especially metaphorical texts referring to the body, animals, and the military, gives their important communications a lively and humane flavor that illustrates their deep friendship, trust, and support of each other. Frequently used as metaphorical arguments, these proverbial interjections into an otherwise factual epistolary exchange from 1933 to 1945 bear witness to the determination of these two world leaders to win the struggle for a free world.

    Full Text Available Infection of Helicobacter pylori since its discovery by Australian doctors Barry Marshall and RobinWarren in 1982 has been one of the scientific phenomena of greater importance in world-wide biomedicalliterature. Since then, numerous investigations have been developed to study this bacterium because itplays a significant role in etiology and pathogenesis of diverse gastrointestinal diseases like chronicgastritis and peptic ulcer, in addition to being a factor of important risk for development of gastric cancer.Cultivation is the most specific method to diagnose this microorganism. Despite its sensibility it variesnotably in relation to different variables: collection, transport and storage of samples; cultivation mediaand incubation conditions. This work evaluated the productivity of three culture media for H. pylorirecovery by ecometric method. All culture media showed low productivity. ICA values were lower than2,5 on all cultivation media. Culture media with ICA values of low and mid production were: Agar ATS:7,6% and 92,3%, Agar BHI: 0% and 100%, Agar Brucella: 6,6% and 93,3%.

    Full Text Available Objective: There are various risk factors which play an essential role in the multifactorial disease “dental caries.” Although absence of interdental spaces in the primary dentition may increase the risk of dental caries, not many studies have been carried out to assess this correlation. This study was performed to assess the relationship between interdental spacing and dental caries in primary dentition.Materials and Methods: Five hundred 4-6 year-old children were enrolled into this study. Dental caries was recorded using the criteria given by Warren et al. Following this, impressions were made for the upper and lower arches and dental casts were poured. Interdental spaces were measured on the dental casts using a digital verniercaliper. The data obtained were subjected to statistical analysis.Results: The number of sites with interdental spaces was higher in the maxillary arch in comparison to the mandibular arch. The highest number of interdental spaces was observed between the maxillary anteriors. The number of demineralized, but non-cavitated tooth surfaces (d1were higher than the number of cavitated tooth surfaces. This difference was significant in the mandibular anterior segment. Dental caries showed a negative correlation with interdental spacing. A significant correlation was found between dental caries and interdental spacing in the posterior segment of the mandibular arch.Conclusion: This study showed that children with no interdental spacing in the primary dentition are at higher risk for dental caries.Key Words: Dental Caries; Interdental Spaces; Interproximal Caries

  6. Non-darcy flow behavior mean high-flux injection wells in porous and fractured formations

    2003-04-25

    This paper presents a study of non-Darcy fluid flow through porous and fractured rock, which may occur near wells during high-flux injection of waste fluids into underground formations. Both numerical and analytical models are used in this study. General non-Darcy flow is described using the Forchheimer equation, implemented in a three-dimensional, multiphase flow reservoir simulator. The non-Darcy flow through a fractured reservoir is handled using a general dual continuum approach, covering commonly used conceptual models, such as double porosity, dual permeability, explicit fracture, etc. Under single-phase flow conditions, an approximate analytical solution, as an extension of the Warren-Root solution, is discussed. The objectives of this study are (1) to obtain insights into the effect of non-Darcy flow on transient pressure behavior through porous and fractured reservoirs and (2) to provide type curves for well test analyses of non-Darcy flow wells. The type curves generated include various types of drawdown, injection, and buildup tests with non-Darcy flow occurring in porous and fractured reservoirs. In addition, non-Darcy flow into partially penetrating wells is also considered. The transient-pressure type curves for flow in fractured reservoirs are based on the double-porosity model. Type curves provided in this work for non-Darcy flow in porous and fractured reservoirs will find their applications in well test interpretation using a type-curve matching technique.

    2018-03-01

    Full Text Available As one of the main lepidopteran pests in Chinese tea plantations, Ectropis obliqua Warren (tea geometrids can severely decrease yields of tea products. The olfactory system of the adult tea geometrid plays a significant role in seeking behaviors, influencing their search for food, mating partners, and even spawning grounds. In this study, a general odorant-binding protein (OBP gene, EoblGOBP2, was identified in the antennae of E. obliqua using reverse transcription quantification PCR (RT-qPCR. Results showed that EoblGOBP2 was more highly expressed in the antennae of males than in females relative to other tissues. The recombinant EoblGOBP2 protein was prepared in Escherichia coli and then purified through affinity chromatography. Ligand-binding assays showed that EoblGOBP2 had a strong binding affinity for some carbonyl-containing tea leaf volatiles (e.g., (E-2-hexenal, methyl salicylate, and acetophenone. Electrophysiological tests confirmed that the male moths were more sensitive to these candidate tea plant volatiles than the female moths. Immunolocalization results indicated that EoblGOBP2 was regionally confined to the sensilla trichoid type-II in the male antennae. These results indicate that EoblGOBP2 may be primarily involved in the olfactory activity of male E. obliqua moths, influencing their ability to sense tea leaf volatiles. This study provides a new perspective of insect GOBPs and implies that olfactory function can be used to prevent and control the tea geometrid.

  8. Selye's general adaptation syndrome: stress-induced gastro-duodenal ulceration and inflammatory bowel disease.

    2017-03-01

    Hans Selye in a note to Nature in 1936 initiated the field of stress research by showing that rats exposed to nocuous stimuli responded by way of a 'general adaptation syndrome' (GAS). One of the main features of the GAS was the 'formation of acute erosions in the digestive tract, particularly in the stomach, small intestine and appendix'. This provided experimental evidence for the view based on clinical data that gastro-duodenal (peptic) ulcers could be caused by stress. This hypothesis was challenged by Marshall and Warren's Nobel Prize (2005)-winning discovery of a causal association between Helicobacter pylori and peptic ulcers. However, clinical and experimental studies suggest that stress can cause peptic ulceration in the absence of H. pylori Predictably, the etiological pendulum of gastric and duodenal ulceration has swung from 'all stress' to 'all bacteria' followed by a sober realization that both factors play a role, separately as well as together. This raises the question as to whether stress and H. pylori interact, and if so, how? Stress has also been implicated in inflammatory bowel disease (IBD) and related disorders; however, there is no proof yet that stress is the primary etiological trigger for IBD. Central dopamine mechanisms seem to be involved in the stress induction of peptic ulceration, whereas activation of the sympathetic nervous system and central and peripheral corticotrophin-releasing factor appears to mediate stress-induced IBD. © 2017 Society for Endocrinology.

    Full Text Available The Obama administration has developed two broad programs to defer immigration enforcement actions against undocumented persons living in the United States: (1 Deferred Action for Parents of Americans and Lawful Permanent Residents (DAPA; and (2 Deferred Action for Childhood Arrivals (DACA. The DACA program, which began in August 2012, was expanded on November 20, 2014. DAPA and the DACA expansion (hereinafter referred to as “DACA-plus” are currently under review by the US Supreme Court and subject to an active injunction.This paper offers a statistical portrait of the intended direct beneficiaries of DAPA, DACA, and DACA-plus. It finds that potential DAPA, DACA, and DACA-plus recipients are deeply embedded in US society, with high employment rates, extensive US family ties, long tenure, and substantial rates of English-language proficiency. The paper also notes various groups that would benefit indirectly from the full implementation of DAPA and DACA or, conversely, would suffer from the removal of potential beneficiaries of these programs. For example, all those who would rely on the retirement programs of the US government will benefit from the high employment rates and relative youth of the DACA population, while many US citizens who rely on the income of a DAPA-eligible parent would fall into poverty or extreme poverty should that parent be removed from the United States.This paper offers an analysis of potential DAPA and DACA beneficiaries. In an earlier study, the authors made the case for immigration reform based on long-term trends related to the US undocumented population, including potential DAPA and DACA beneficiaries (Warren and Kerwin 2015.

    crystallization of the angrites occurred when the solar system was still extremely young, and apparently data of [4] eliminate 26Al as a potential heat source for magmatism. The angrite volatile pattern may be the product of heating by an intense, short-lived heat source that melted and partially vaporized the crust of an asteroid(s) (not necessarily the final angrite asteroid), without much affecting the deep interior(s), which later (through mixing and/or magmatism) replenished the angritic materials in most volatiles, but not alkalis and Ga. Exogenic heating, as in the often-conjectured (but hard to test) hypothesis that a major early heat source was enhanced solar luminosity (as in FU-Orionis cycles), would seem to be required. LEW 87051 and A881371 are rich in compositionally diverse olivine xenocrysts, and A881371 contains a possible FeS xenocryst [7]. These, and the angrites' great siderophile diversity [3], tend to suggest that magmatism and intensely disruptive cratering (with mixing of precursor materials) were contemporaneous. This scenario is admittedly speculative, but the volatile-depletion pattern is difficult to rationalize with any other model. References: [1] Prinz M. and Weisberg M. (1995) Antarct.

    Stable carbon isotopic analysis, in combination with compositional analysis, was used to evaluate the performance of an iron permeable reactive barrier (PRB) for the remediation of ground water contaminated with trichloroethene (TCE) at Spill Site 7 (SS7), F.E. Warren Air Force Base, Wyoming. Compositional data indicated that although the PRB appeared to be reducing TCE to concentrations below treatment goals within and immediately downgradient of the PRB, concentrations remained higher than expected at wells further downgradient (i.e. > 9 m) of the PRB. At two wells downgradient of the PRB, TCE concentrations were comparable to upgradient values, and δ13C values of TCE at these wells were not significantly different than upgradient values. Since the process of sorption/desorption does not significantly fractionate carbon isotope values, this suggests that the TCE observed at these wells is desorbing from local aquifer materials and was present before the PRB was installed. In contrast, three other downgradient wells show significantly more enriched δ13C values compared to the upgradient mean. In addition, δ13C values for the degradation products of TCE, cis-dichloroethene and vinyl chloride, show fractionation patterns expected for the products of the reductive dechlorination of TCE. Since concentrations of both TCE and degradation products drop to below detection limit in wells within the PRB and directly below it, these downgradient chlorinated hydrocarbon concentrations are attributed to desorption from local aquifer material. The carbon isotope values indicate that this dissolved contaminant is subject to local degradation, likely due to in situ microbial activity.

    A case of synchronous triple urogenital cancer, which was comprised of renal cell carcinoma of the left kidney, transitional cell carcinoma of the urinary bladder, and adenocarcinoma of the prostate, is reported. A 72-year-old Japanese male patient was referred to our outpatient clinic with the complaint of asymptomatic hematuria. At that time, his serum of level of PSA was elevated to 20 ng/ml. Cystourethroscopy showed a papillary bladder tumor and coagula through the left urinary orifice. Ultrasonography, computed tomography and magnetic resonance imaging showed a mass lesion measuring about 6 cm by 5 cm in the left kidney. Angiography showed a hypervascular lesion measuring about 6 cm by 5 cm at the same site. Double cancer, consisting of renal cell carcinoma and transitional cell carcinoma of the urinary bladder, was suspected and we performed left total nephroureterectomy, hilar lymphadenectomy, and transurethral rection of the bladder tumor, one month later. At the same time, we performed a biopsy of the prostate. Histological diagnosis was renal cell carcinoma, clear cell carcinoma and transitional cell carcinoma of urinary bladder. Histological diagnosis of the prostate biopsy was moderately differentiated adenocarcinoma. Since this case fulfilled the criteria of Warren and Gates, it was classified as synchronous triple urogenital cancer. A review of the literature revealed 17 authentic cases of triple urogenital cancer, of which 14 and 10 cases were reported as a combination of renal cancer, bladder cancer and prostatic cancer, in the world and in Japan, respectively. Furthermore, he had been exposed to the atomic bomb explosion in Hiroshima in 1945. This carcinogenic precursor may be related to the development of the triple cancer. (author)

    Full Text Available The Foreign Affairs journal is an important asset for analysis of American foreign policy and the most important global topics for nearly a century. In the 1990-ties many of the authors in this journal dealt with the issue of Yugoslavia – the disintegration of the Socialist Federal Republic of Yugoslavia and a series of wars that followed on its former territory. The Yugoslav crisis was analyzed by the different authors: theorists, prominent journalists, and politicians that were directly involved in different stages of the Yugoslav crisis, such as David Owen, Warren Zimmerman or Carl Bildt. Most of the attention was devoted to the conflicts in Bosnia and Herzegovina and Kosovo. The causes of the Yugoslav tragedy were analyzed, in many articles on the Yugoslav wars in the 1990s, published in Foreign Affairs, with a special focus on origins of internal tensions that preceded the tragic collapse of the Yugoslavia. The most frequent topic of those articles, was the role of foreign factors in crisis and wars in the former Yugoslavia. The issue of international recognition of the breakaway Yugoslav republics at the beginning of the wars, and NATO air strikes against the Federal Republic of Yugoslavia in 1999 was specifically addressed. Several Foreign Affairs articles published the nineties and the early years of the millennium evaluated of the political situation in countries of the former Yugoslavia in the post-conflict period. Common to almost all authors who were analyzing this subject are negative remarks on the post-war development in parts of the former Yugoslavia, which were mostly affected by the crisis and wars of the 90s. An integral part of the contence in those articles, were recommendations of authors to those international actors who are able to influence the processes in the former Yugoslavia.

    Full Text Available New World plants, such as tobacco, tomato, and chili, were held to have beneficial effects on the eyes. Indigenous healers rubbed or scraped the eyes or eyelids to treat inflammation, corneal opacities, and even eye irritation from smoke. European settlers used harsh treatments, such as bleeding and blistering, when the eyes were inflamed or had loss of vision with a normal appearance (gutta serena. In New Spain, surgery for corneal opacity was performed in 1601 and cataract couching in 1611. North American physicians knew of contralateral loss of vision after trauma or surgery (sympathetic ophthalmia, which they called “sympathy.” To date, the earliest identified cataract couching by a surgeon trained in the New World was performed in 1769 by John Bartlett of Rhode Island. The American Revolution negatively affected ophthalmology, as loyalist surgeons were expelled and others were consumed with wartime activities. After the war, cataract extraction was imported to America in earnest and academic development resumed. Charles F Bartlett, the son of John, performed cataract extraction but was also a “rapacious privateer.” In 1801, a doctor in the frontier territory of Kentucky observed anticholinergic poisoning by Datura stramonium (Jimsonweed and suggested that this agent be applied topically to dilate the pupil before cataract extraction. John Warren at Harvard preferred couching in the 1790s, but, after his son returned from European training, recommended treating angle closure glaucoma by lens extraction. Other eye procedures described or advertised in America before the 19th century included enucleation, resection of conjunctival lesions or periocular tumors, treatment of lacrimal fistula, and fitting of prosthetic eyes.

    Full Text Available Leonard F Vernon Sherman College of Chiropractic, Spartanburg, SC, USA Abstract: The standard definition of spontaneous regression (SR of cancer is as follows, “…when a malignant tumor partially or completely disappears without treatment or in the presence of therapy which is considered inadequate to exert a significant influence on neoplastic disease.” SR is also known as Saint Peregrine tumor, the name taken from a young priest, Peregrine Laziosi (1260 [5]–1345, exact date is unknown, who had been diagnosed with a tumor of the tibia. The mass eventually grew so large that it broke through the skin and became severely infected. The available treatment for this condition was limited to amputation. Historical records report that on the day of surgery, physicians found that the tumor had disappeared and reportedly never returned. To date, the medical literature consists only of individual case studies and overviews of this phenomenon. The most cited work on the subject was done by surgeons Tilden Everson and Warren Cole who reviewed 176 published cases of SR from 1900 to 1960. While a percentage of these were found not to be cases of SR, there remained a number of unexplained cases. A frequent theme in many cases of SR is the co-occurrence of infection. Given the current interest in immunotherapy in the treatment of cancer, this article discusses one of the very early pioneers of this theory, William Bradley Coley, MD, a surgeon who was clearly ahead of his time. Ostracized by colleagues for his belief that stimulation of the immune system could in fact produce a regression of cancer, Coley remained convinced that his theory was right and, while he was not familiar with cytokines such as tumor necrosis factor (TNF, interferons, and streptokinase, he knew instinctively that an innate immune response was taking place.

    Susan Band Horwitz is a Distinguished Professor and holds the Falkenstein Chair in Cancer Research at Albert Einstein College of Medicine in New York. She is co-chair of the Department of Molecular Pharmacology and associate director for therapeutics at the Albert Einstein Cancer Center. After graduating from Bryn Mawr College, Dr. Horwitz received her PhD in biochemistry from Brandeis University. She has had a continuing interest in natural products as a source of new drugs for the treatment of cancer. Her most seminal research contribution has been in the development of Taxol(®). Dr. Horwitz and her colleagues made the discovery that Taxol had a unique mechanism of action and suggested that it was a prototype for a new class of antitumor drugs. Although Taxol was an antimitotic agent blocking cells in the metaphase stage of the cell cycle, Dr. Horwitz recognized that Taxol was blocking mitosis in a way different from that of other known agents. Her group demonstrated that the binding site for Taxol was on the β-tubulin subunit. The interaction of Taxol with the β-tubulin subunit resulted in stabilized microtubules, essentially paralyzing the cytoskeleton, thereby preventing cell division. Dr. Horwitz served as president (2002-2003) of the American Association for Cancer Research (AACR). She is a member of the National Academy of Sciences, the Institute of Medicine, the American Academy of Arts and Sciences, and the American Philosophical Society. She has received numerous honors and awards, including the C. Chester Stock Award from Memorial Sloan Kettering Cancer Center, the Warren Alpert Foundation Prize from Harvard Medical School, the Bristol-Myers Squibb Award for Distinguished Achievement in Cancer Research, the American Cancer Society's Medal of Honor, and the AACR Award for Lifetime Achievement in Cancer Research.
