    The usage of Artificial Neural Networks (ANNs) for genome-enabled classifications and establishing genome-phenotype correlations have been investigated more extensively over the past few years. The reason for this is that ANNs are good approximates of complex functions, so classification can be performed without the need for explicitly defined input-output model. This engineering tool can be applied for optimization of existing methods for disease/syndrome classification. Cytogenetic and molecular analyses are the most frequent tests used in prenatal diagnostic for the early detection of Turner, Klinefelter, Patau, Edwards and Down syndrome. These procedures can be lengthy, repetitive; and often employ invasive techniques so a robust automated method for classifying and reporting prenatal diagnostics would greatly help the clinicians with their routine work. The database consisted of data collected from 2500 pregnant woman that came to the Institute of Gynecology, Infertility and Perinatology "Mehmedbasic" for routine antenatal care between January 2000 and December 2016. During first trimester all women were subject to screening test where values of maternal serum pregnancy-associated plasma protein A (PAPP-A) and free beta human chorionic gonadotropin (β-hCG) were measured. Also, fetal nuchal translucency thickness and the presence or absence of the nasal bone was observed using ultrasound. The architectures of linear feedforward and feedback neural networks were investigated for various training data distributions and number of neurons in hidden layer. Feedback neural network architecture out performed feedforward neural network architecture in predictive ability for all five aneuploidy prenatal syndrome classes. Feedforward neural network with 15 neurons in hidden layer achieved classification sensitivity of 92.00%. Classification sensitivity of feedback (Elman's) neural network was 99.00%. Average accuracy of feedforward neural network was 89.6% and for

    British astronomy lost one of its most respected and liked members with the sudden death of Dr Timothy (Tim) Hawarden. Hawarden was one of those people who changed his wavelength and discipline as the emerging challenges of astronomy dictated, and was successful in all of his ventures. He experienced a huge breadth of achievement; moving from photographic plates, through electronic detectors to infrared astronomy from the ground and subsequently from space. He was an acknowledged leader in his fields around the world and, in addition to his professional accomplishments, he was a keen practitioner of culinary technique. His bouillabaisse was legendary. In his later years he was a source of inspiration for young children in his outreach work. Tim Hawarden began his career as an optical astronomer in South Africa. He graduated from the University of Natal, Pietermaritzburg in 1966 with a BSc in Physics and Applied Mathematics, followed by an MSc in Astronomy from the University of Cape Town in 1970 and a PhD in 1975. Hawarden's early years were formed by learning the precise art of photometry from the legendary Cousins, and this focus on precision has stood him in good stead throughout his career. He then moved Australia in 1975, where he spent three years as Deputy Astronomer-in-Charge of the UK Schmidt Telescope, from where he moved to the Royal Observatory Edinburgh, where he remained for the rest of his career. Hawarden rapidly moved into the newly emerging field of infrared astronomy. His research moved from stars and stellar clusters to barred spiral galaxies and he was keen to employ the new tools coming on-line to pursue this work. The United Kingdom Infrared Telescope (KIRT) was the world's premier facility and Tim Hawarden became the Head of the unit at the ROE in 1981, a post he held for the next six years, overseeing a range of developments that have stood the test of time and have provided the platform on which UKIRT has retained its world-class standing

    Spleen cells from LAF1 mice were stimulated in a microculture system with T and B cell mitogens or antigens of timothy pollen. Only cells from mice immunized with crude timothy pollen extract (WST) or a major antigen of timothy pollen conjugated to Ascaris (antigen B-Ascaris) responded to timothy antigens in vitro. Optimum responses were obtained at 120 to 144 hr of culture with 5 to 10 mug WST per culture and ranged from three to 10 times greater than cell background. No correlations could be found between the optimum antigen concentration or the maximum response and the immune status of the spleen cell donor. Response could be inhibited by a dialyzable fraction of timothy pollen, antigen D, which is a monovalent form of a major antigen of timothy pollen.

    Serum samples were collected from eight grass pollen hypersensitive children during a 4-year period. The sera were assayed for contents of timothy-specific IgE antibodies by RAST. Timothy-specific IgG and IgA antibodies were quantified by a refined ELISA in which covalent binding of the antigen to the polystyrene solid phase had been performed. IgG antibodies were also assayed by a Sepharose-protein-A technique with radiolabelled timothy allergens as the antigen. It was possible to register clearcut seasonal variations with postseasonally boosted antibody levels not only of timothy-specific IgE but also of IgG antibody. Both IgG1 and IgG4 antibodies specific for timothy showed seasonal variations of a similar degree. It was not possible to register seasonal variations of the same magnitude of timothy-specific IgA antibodies.

    Edward Teller died on September 9, 2003 in Stanford, California at the age of 95. He was both one of the great theoretical physicists of the twentieth century and a leading figure in the development of nuclear weapons and broader defense advocacy. Teller's work in physics, spanning many decades of the twentieth century, includes some of the most fundamental insights in the quantum behaviors of molecules and their spectra, nuclei, surfaces, solid state and spin systems, and plasmas. In the defense arena, Teller is best known for his key insight that made thermonuclear weapons possible. Teller was both a great scientific collaborator and physics teacher at all levels, known for his openness, generosity, personal warmth, and powerful physical intuition. Many of his graduate students went on to illustrious careers.

    Edward A. Bouchet was the first African American to receive the doctorate in any field of knowledge in the United States and that area was physics. He was granted the degree in 1876 from Yale University making him at that time one of the few persons to hold the physics doctorate from an American university. His prior education included the Hopkins Grammar School and Yale College (BA in 1874). After Yale, Bouchet taught mathematics, physics, and chemistry for over twenty-five years at the Institute for Colored Youth in Philadelphia. During the following two decades, he was employed in positions ranging from high school principal to employment by the federal government. Bouchet played a significant role in the education of African Americans through his teaching and mentoring activities. He was one among a small group of African Americans who achieved advanced training and education within decades of the American civil war. These individuals provided direction, leadership, and role models for what eventually became the civil/human rights movements. The year 2001 marks the 125th celebration of his receiving the doctorate. We present details of his life and career with an emphasis on the influence of the political and social forces exerted on him by society.

  20. Lessons from Queer Bioethics: A Response to Timothy F. Murphy.

    Science.gov (United States)

    Richie, Cristina

    2016-06-01

    'Bioethics still has important work to do in helping to secure status equality for LGBT people' writes Timothy F. Murphy in a recent Bioethics editorial. The focus of his piece, however, is much narrower than human rights, medical care for LGBT people, or ending the HIV/AIDS pandemic. Rather, he is primarily concerned with sexuality and gender identity, and the medical intersections thereof (i.e. DSM diagnosis; access to SrS or ARTs). It is the objective of this response to provide an alternate account of bioethics from a Queer perspective. I will situate Queer bioethics within Queer studies, and offer three 'lessons' that bioethics can derive from this perspective. These are not definitive rules for Queer bioethics, since it is a field which fundamentally opposes categorizations, favoring pastiche over principles. These lessons are exploratory examples, which both complement and contradict LGBT bioethics. My latter two lessons - on environmental bioethics and disability - overlap with some of Murphy's concerns, as well as other conceptions of LGBT bioethics. However, the first lesson takes an antithetical stance to Murphy's primary focus by resisting all forms of heteroconformity and disavowing reproduction as consonant with Queer objectives and theory. The first lesson, which doubles as a primer in Queer theory, does heavy philosophical lifting for the remainder of the essay. This response to Timothy F. Murphy, whose work is certainly a legacy in bioethics, reveals the multiplicity of discourses in LGBT/Queer studies, many of which are advantageous - even essential - to other disciplines like bioethics. © 2016 John Wiley & Sons Ltd.

  4. EDWARD SUESS AND RUSSIAN GEOLOGISTS

    Directory of Open Access Journals (Sweden)

    Boris A. Natal’in

    2011-01-01

    Full Text Available The publication is devoted to the history of one of the greatest concepts of tectonics of Asia, that has been widely accepted and yet obliterated with time, while the splendors of this concept are doubtful. Numerous citations in the Russian papers to «The Face of the Earth» by Edward Suess and the fact that he was elected a Corresponding Member of the Imperial Saint Petersburg Academy of Sciences clearly demonstrate how highly Suess’s contribution to studies of the structure and geological evolution of Asia was valued by the Russian geological community. Suess’s letters to Vladimir A. Obruchev give evidence how close and productive the relationship between Edward Suess and the Russian researchers was in the late 19th and the early 20th centuries and also illustrate how the great tectonic concept of Asia [Suess, 1908] was born and developed. The idea of centrifugal propagation of tectonic waves of the Altaids from a continental node located somewhere in Siberia was mainly inspired by Suess’s profound scientific intuition. The idea matured after Edward Suess got acquainted with Ivan D. Chersky’s paper [Черский, 1886] that greatly facilitated in shaping and improving this idea. It was mailed to Suess by Vladimir A. Obruchev who translated the paper, attached his own map and provided explanations to Chersky’s ideas. The available historical documents suggest that Vladimir A. Obruchev facilitated communication between the Russian geologists, on the one side, and Edward Suess and other Austrian geologists who conducted geological studies in Asia, on the other side. Being actively involved in exchange of publications and cooperation in field data processing, Edward Suess was aware of all the details of the Russian geological studies.In addition to the concept of tectonic arcs of the Altaids and descriptions of main geological structures located in Northern Asia and China, Edward Suess adopted a concept of disjunctive dislocations

  7. Mapping swamp timothy (Cripsis schenoides) seed productivity using spectral values and vegetation indices in managed wetlands

    Rahilly, P.J.A.; Li, D.; Guo, Q.; Zhu, J.; Ortega, R.; Quinn, N.W.T.; Harmon, T.C.

    2010-01-15

    This work examines the potential to predict the seed productivity of a key wetland plant species using spectral reflectance values and spectral vegetation indices. Specifically, the seed productivity of swamp timothy (Cripsis schenoides) was investigated in two wetland ponds, managed for waterfowl habitat, in California's San Joaquin Valley. Spectral reflectance values were obtained and associated spectral vegetation indices (SVI) calculated from two sets of high resolution aerial images (May 11, 2006 and June 9, 2006) and were compared to the collected vegetation data. Vegetation data were collected and analyzed from 156 plots for total aboveground biomass, total aboveground swamp timothy biomass, and total swamp timothy seed biomass. The SVI investigated included the Simple Ratio (SR), Normalized Difference Vegetation Index (NDVI), Soil Adjusted Vegetation Index (SAVI), Transformed Soil Adjusted Vegetation Index (TSAVI), Modified Soil Adjusted Vegetation Index (MSAVI), and Global Environment Monitoring Index (GEMI). We evaluated the correlation of the various SVI with in situ vegetation measurements for linear, quadratic, exponential and power functions. In all cases, the June image provided better predictive capacity relative to May, a result that underscores the importance of timing imagery to coincide with more favorable vegetation maturity. The north pond with the June image using SR and the exponential function (R{sup 2}=0.603) proved to be the best predictor of swamp timothy seed productivity. The June image for the south pond was less predictive, with TSAVI and the exponential function providing the best correlation (R{sup 2}=0.448). This result was attributed to insufficient vegetal cover in the south pond (or a higher percentage of bare soil) due to poor drainage conditions which resulted in a delay in swamp timothy germination. The results of this work suggest that spectral reflectance can be used to estimate seed productivity in managed seasonal

    1982-01-01

    Perennial desensitization therapy was given during a period of 3.5 years to 40 children allergic to grass pollen allergens. 20 patients were treated with a crude and another 20 with a purified timothy pollen extract. 8 children served as untreated controls. The concentration of total and specific IgE in the treated groups covaried with those in the control group. Neither a suppression of the seasonal booster effect nor a suppression of IgE synthesis attributable to the treatment was found. The rise of timothy-specific "blocking' IgG antibodies was more pronounced in the group treated with the purified extract than in the group treated with the crude extract. A significant difference was found only after 3.5 years of treatment. The amplitude of rise of IgG antibodies correlated significantly with the effect of the treatment as judged by repeated conjunctival titration test. The results suggest that a good IgG response is an indication of successful therapy and that a better IgG response may be achieved with purified allergen extracts.

  9. Fuelwood production in Prince Edward Island

    International Nuclear Information System (INIS)

    McCallum, B.

    1992-01-01

    The most recent Prince Edward Island Fuelwood Survey occurred in 1990-91. Consumption of fuelwood rose again to 49% of Prince Edward Island's 43,170 households. Total residential fuelwood consumption was estimated to be 242,000 m 3 . The fuelwood industry makes an important contribution to the economy of Prince Edward Island. In the 1990-91 heating season, fuelwood valued at USD 9 million displaced approximately 43 million litres of domestic heating oil valued at USD 16.4 million. In addition, it is estimated that 70 cents of every dollar spent on fuelwood remains in the province and contributes spin-off benefits, whereas 90 cents of every dollar spent on heating oil is lost to the economy of Prince Edward Island. The percentage of people cutting their own fuelwood decreased from 52 in 1984-85 to only 23.4 in 1990-91. The governments of Canada and Prince Edward Island have implemented a series of Forest Resource Development Agreements (FRDAs) starting in 1983. The current 1988-1993 FRDA provides USD 24 million for research and incentives for reforestation and management of Prince Edward Island woodlots. It is expected that 3,800 Prince Edward Island woodlot owners will be participating in a woodlot management program by 1993. Silviculture treatments of hardwood stands include thinning, stand conversion (removal of lowgrade softwoods such as balsam fir in mainly hardwood stands), and shelterwood (strip) cutting, particularly in marginal stands.

    The STS-29 Space Shuttle Discovery mission lands at NASA's then Ames-Dryden Flight Research Facility, Edwards AFB, California, early Saturday morning, 18 March 1989. Touchdown was at 6:35:49 a.m. PST and wheel stop was at 6:36:40 a.m. on runway 22. Controllers chose the concrete runway for the landing in order to make tests of braking and nosewheel steering. The STS-29 mission was very successful, completing the launch of a Tracking and Data Relay communications satellite, as well as a range of scientific experiments. Discovery's five-man crew was led by Commander Michael L. Coats, and included pilot John E. Blaha and mission specialists James P. Bagian, Robert C. Springer, and James F. Buchli. Space Shuttles are the main element of America's Space Transportation System and are used for space research and other space applications. The shuttles are the first vehicles capable of being launched into space and returning to Earth on a routine basis. Space Shuttles are used as orbiting laboratories in which scientists and mission specialists conduct a wide variety of scientific experiments. Crews aboard shuttles place satellites in orbit, rendezvous with satellites to carry out repair missions and return them to space, and retrieve satellites and return them to Earth for refurbishment and reuse. Space Shuttles are true aerospace vehicles. They leave Earth and its atmosphere under rocket power provided by three liquid-propellant main engines with two solid-propellant boosters attached plus an external liquid-fuel tank. After their orbital missions, they streak back through the atmosphere and land like airplanes. The returning shuttles, however, land like gliders, without power and on runways. Other rockets can place heavy payloads into orbit, but, they can only be used once. Space Shuttles are designed to be continually reused. When Space Shuttles are used to transport complete scientific laboratories into space, the laboratories remain inside the payload bay throughout

    2009-01-01

    Full Text Available We review Timothy Vang’s dissertation on the growth and decline of the Hmong Christian church. We argue that Vang’s arguments are methodologically and theoretically flawed. Furthermore, we try to show that his dissertation is not so much an objective analysis of Hmong religious adaptation, but rather an attempt to define and subjugate certain Hmong cultural and religious beliefs and practices as backward and inferior to Christianity. We suggest that it is these kinds of problematic arguments, often couched in academic language, that further perpetuate misinterpretations and misrepresentations about “culture” and “religion” in Hmong American communities.

  17. „Skrwawione ziemie” Timothy Snydera. Krytyczne uwagi na temat konstrukcji krajobrazu historycznego

    Jürgen Zarusky

    2012-12-01

    Full Text Available Timothy Snyder’s "Bloodlands". Critical comments on the construction of historical landscape Jürgen Zarusky's text is an extensive deconstruction of Timothy Snyder's narration presented in Bloodlands. The narration is based on the assumption, that both regimes – Nazi and Soviet – and their extermination practicies were similar. In Bloodlands Stalin's crimes are presented as a form of ethnic extermination. Thus Snyder suggested ideological kinship between both dictators without analysing specific ideologies. Although the author specifies the differences between these two ideologies he does not ask about their significance to the enemy image and extermination practicies. Snyder's narration concentrates excessively on Poland – as the core of “bloodlands”. In the closing chapter of the book Poles are depicted as the actual martyrs of “bloodlands” in Poland, as well as on the territory of the Soviet Union. Yet up to this day there are ethinc gorups – like Sinti and Romany -  who have to fight for the recognition of their tragic experiences as the victims of crimes commited by German authorities. The author also does not mention about the victims of the agressive wars against the Soviet Union. Thus the point of Bloodlands is not to present all the victims of totalitarianism and the war, all the victims from “bloodlands”, but to present only the victims selected by the author.   „Skrwawione ziemie” Timothy Snydera.

    1995-01-01

    Full Text Available Three male reindeer (Rangifer tarandus tarandus calves were brought from mountain pastures in April and fed regrowth timothy (Phleum pratense silage with 76% leaves and 24.0% dry matter (DM ad libitum. The silage contained (on DM basis 25.4% cellulose, 12.0% crude protein and 19-6% water soluble carbohydrates. After an initial period of 11 days the daily silage intake rose to almost similar values for all animals, but independently of food intake, body mass (BM increased by as much as 13.3 kg for animal R3 during the first 21 days, compared to 4.4 kg and 2.8 kg for Rl and R2, respectively. At slaughter the wet weight of the rumen contents of animal R3 constituted 30.2% of the total BM, compared to 18.5% and 19.1% in animals Rl and R2, respectively. A reduced ability of the rumen micro-biota to ferment pure cellulose in vitro was observed in R3. The ruminal pH was 7.07 and the concentration of volatile fatty acids was only 50.0 mM in R3, indicating a low rate of fermentation. The initial rates of in vitro dry matter digestibility of timothy silage and standard hay were also affected by the rumen fermentation failure in animal R3. Depressed rumen cellulolysis, which may be related to natural periods of starvation prior to the feeding experiment, could have caused the low rate of fermentation and the large rumen size observed in this animal.

  20. Granular statistical mechanics - Building on the legacy of Sir Sam Edwards

    Science.gov (United States)

    Blumenfeld, Raphael

    When Sir Sam Edwards laid down the foundations for the statistical mechanics of jammed granular materials he opened a new field in soft condensed matter and many followed. In this presentation we review briefly the Edwards formalism and some of its less discussed consequences. We point out that the formalism is useful for other classes of systems - cellular and porous materials. A certain shortcoming of the original formalism is then discussed and a modification to overcome it is proposed. Finally, a derivation of an equation of state with the new formalism is presented; the equation of state is analogous to the PVT relation for thermal gases, relating the volume, the boundary stress and measures of the structural and stress fluctuations.

    The responsiveness to a nonendemic grass species is unknown and cannot be research without an allergen challenge chamber. To determine the clinical responsiveness to timothy grass pollen (TGP) in participants without known natural exposure in an allergen challenge chamber (ACC). Of the 26 screened participants, 22 met screening criteria and completed the 2 chamber exposures. The study consisted of an initial screening visit that included a blood draw for serum specific IgE (ssIGE) to Bermuda grass pollen and TGP followed by a 4½-day run-in phase and two 3-hour ACC exposure visits. This study was performed early in the first week of December 2013, when no seasonal pollens were detected in San Antonio, Texas. Symptom scores were recorded at baseline and every 30 minutes. Of the 26 screened participants, 22 met the screening criteria and completed the 2 chamber exposures. Thirteen participants had always lived in South Texas without natural exposure, and 9 had previously lived in areas with TGP exposure. All participants tested positive to TGP and Bermuda grass pollen. Twelve and 13 of 22 had positive ssIgE test results to Timothy and Bermuda allergens, respectively, with 11 having positive results for both allergens. There were strong correlations among skin prick test size, a positive ssIgE test result, and high symptoms from TGP exposure. There was little difference in symptoms between those who had lived their entire lives in South Texas and those who had lived elsewhere. In Texas, where exposure to TGP is minimal, strongly positive SPT and ssIgE test results were predictors of high symptoms to TGP exposure. Never exposed participants in South Texas reacted to TGP similar to those who had previous natural exposure, suggesting that in vivo cross-reactivity may be higher than predicted by prior in vitro data and may allow the use in clinical trials of allergens not endemic to the locale of an ACC.

    Full Text Available Timothy grass given N fertilizer at the rates of 40, 80 and 120 kg N/ha was preserved in 3 glass-fibre silos of 0.4 m3. The crude protein content of DM in the grass increased with the increase of N fertilization as follows: N40 14.8 %, N80 18.4 % and N120 22.1 %, but the proportion of true protein in crude protein decreased: N40 82 %, N80 78 % and N120 76 %. The proportion of watersoluble N in the total N in the grass was: N40 27 %, N80 30 % and N120 33 %. The higher was the N fertilization level, the more rapidly was the protein of the grass degraded in the rumen. The amino acid profile of the protein was similar at all the N fertilization levels. The quality of all the silages was good. The NH3-N fraction of total N was 2.8—3.9 % and the proportion of water-soluble N in total N was 51—55 %, In silage the decrease during ensiling in the proportion of true protein in crude protein and the increase in the proportion of water-soluble N in total N were smaller than in the other silages. The rumen degradability of protein during the first two hours was also lowest in this silage.

    We describe the first report of an Edwards SAPIEN valve implanted in a tricuspid bioprosthesis from the femoral vein. We highlight the feasibility of this previously avoided approach and the techniques involved. A 61-year-old woman with multiple valve replacements for rheumatic heart disease presented with NHYA IV dyspnoea secondary to a severely stenosed tricuspid bioprosthesis. After failed aggressive medical therapy and surgical turn down, an Edwards SAPIEN XT valve was deployed in the tricuspid bioprosthesis via the right femoral vein. Adaptations to the standard transfemoral transcatheter aortic valve implantation (TAVI) technique included: (1) crossing the tricuspid bioprosthesis with a balloon floatation catheter; (2) temporary pacing wire in the coronary sinus rather than the right ventricle; (3) mounting of the SAPIEN XT valve in the reverse orientation to transfemoral TAVI; and (4) fine positioning of the final valve position pre-deployment by 3D transoesophageal echocardiography (3D TOE) alone due to complete radiolucency of the tricuspid bioprosthesis. The procedure was completed without complication and resulted in significant symptomatic improvement. Deployment of an Edwards SAPIEN valve in a tricuspid bioprosthesis via the femoral vein is feasible and, with careful adaptations to established TAVI techniques, can be performed without complications and with good clinical response.

    2010-12-01

    Full Text Available Based on the idea that culture and identities involve a politically built process, the importance of the concepts of representation and imperialism in the work of Edward Said is discussed. The article analyses two of the author’s general proposals. Firstly, the thesis of the centrality of cultural dimension in political relations, which leads to the review of postulates that consider culture as a mere reflection of a phenomena seen as essential or as a sphere isolated from the power practices. Secondly, the study examines how the author’s conception of imperialism is used as a means of identification that keep structures of authority and hegemony, which, in turn, may be defied by processes of resistance. Finally, the validity of the open character of Said’s political theory is debated, which encompasses both the power of representations and an action of political questioning.

    This McDonnell Douglas MD-11 approaches the first landing ever of a transport aircraft under engine power only on Aug. 29, 1995, at NASA's Dryden Flight Research Center, Edwards, California. The milestone flight, flown by NASA research pilot and former astronaut Gordon Fullerton, was part of a NASA project to develop a computer-assisted engine control system that enables a pilot to land a plane safely when it normal control surfaces are disabled. The Propulsion-Controlled Aircraft (PCA) system uses standard autopilot controls already present in the cockpit, together with the new programming in the aircraft's flight control computers. The PCA concept is simple--for pitch control, the program increases thrust to climb and reduces thrust to descend. To turn right, the autopilot increases the left engine thrust while decreasing the right engine thrust. The initial Propulsion-Controlled Aircraft studies by NASA were carried out at Dryden with a modified twin-engine F-15 research aircraft.

  14. Timothy Leary, Richard Alpert (Ram Dass) and the changing definition of psilocybin.

    Science.gov (United States)

    Wark, Colin; Galliher, John F

    2010-05-01

    This research focuses on the events leading to the 1968 U.S. federal prohibition of psilocybin. It is a study of duelling moral entrepreneurs-Timothy Leary and Richard Alpert vs. the Harvard University Administration. The goal is to show how the primary active compound in an ostensibly harmless fungus (the psilocybin mushroom) became controversial in less than a decade. We used books, newspapers, magazine articles and previously unpublished materials (including documents from the Harvard Archives) to analyze Leary and Alpert's lives and careers through the early 1970s. The prohibition of psilocybin in the U.S. was largely a product of Leary and Alpert's involvement in the "Harvard drug scandal" and their transformation from Harvard professors to countercultural icons. They tested the substance on a variety of human subjects and in doing so piqued the interest of Harvard undergraduates while drawing condemnation from other faculty and Harvard administrators. This case is theoretically interesting because unlike most illegal drugs, psilocybin was never linked to a threatening minority group, but to some of the nation's most privileged youth. The Harvard administrators were not really moral entrepreneurs but Leary and Alpert clearly were. Although they were far from being prohibitionists, they were self-righteous crusaders on different but equally holy missions for the good of young and minority Americans. Ironically, due to their successes the possession of psilocybin was criminalized under United States federal law in 1968 (Pub. L. No. 90-639, Stat. 1361 1968 and Boire, 2002). This case study demonstrates that crusaders can be successful in changing culture even when laws are passed in futile attempts to control their behaviour, just as Leary predicted.

    2007-12-01

    Donald Edward Osterbrock, one of the leading figures of post-World War II astronomy, died suddenly of a heart attack on 11 January 2007, while walking near his office at the University of California, Santa Cruz. He was 82 years old. His initials spelled D.E.O. (God in latin!), but he was known simply as Don to his many friends and colleagues. Don's long and productive career spanned five decades. His scientific work helped shape our understanding of lower main-sequence stars, the ionized interstellar medium, and active galactic nuclei. He was also a highly respected historian of astronomy who shed new light on 19th- and 20th-century astronomy. Don was born in Cincinnati, Ohio, on 13 July 1924. Both of his parents were of German descent and valued hard work, education, and science. They both completed their high-school education at night while working full-time during the day. His father eventually became a professor of electrical engineering at the University of Cincinnati. Don's plan to become an astronomer was put on hold when the Japanese attacked Pearl Harbor in 1941. After graduation from high school, Don joined the United States Army and trained as a meteorologist, taking all of the physics and mathematics courses required for a bachelor's degree in physics from the University of Chicago. He was eventually sent to islands in the Pacific Ocean but never was in harm's way. After three years of service, Don returned to Chicago to obtain his bachelor's degree in 1948, his M.S. in astronomy in 1949, and a Ph.D. in astronomy in 1952. Don's years at the University of Chicago and the University's Yerkes Observatory in Williams Bay, Wisconsin, were pivotal for his career and personal life. He came in contact with such luminaries as Otto Struve, Bengt Strömgren, Subrahmanyan Chandrasekhar, and William W. Morgan. At Yerkes, he also met and married Irene L. Hansen, a native of Williams Bay, who was employed as a member of the Yerkes staff. They had a son, William, now

    This work investigated the effects of feeding silage mixtures of a plant containing polyphenol oxidase (PPO; red clover [; RC]), a plant containing tannins (sainfoin [; SF]), and a grass species not containing these compounds (timothy [; T]) on ruminal and intramuscular (i.m.) fatty acids of lambs. Forty 4-mo-old castrated male Romane lambs, divided into 5 groups, received 1 of the following silages: 1) T (100%), 2) a binary mixture of timothy and tannin-containing sainfoin ( cv. Perly; 50:50 [T-SF]), 3) a binary mixture of timothy and PPO-containing red clover ( cv. Mervius; 50:50 [T-RC]), 4) a ternary mixture of timothy, sainfoin, and red clover containing both tannins and PPO (50:25:25, respectively [T-SF-RC]), and 5) a binary mixture of tannin-containing sainfoin and PPO-containing red clover (50:50 [SF-RC]). In the rumen digesta, the partial or total replacement of T with forage legumes was associated with greater concentrations of PUFA ( forage legumes in the silage favored the accumulation of 18:3 -3 ( Forage legumes decreased the -11 18:1 to 30% of T in rumen digesta ( Forage legumes decreased the total concentration of branched-chain fatty acids in the rumen digesta (on average, -28%; comparison with T.

    Full Text Available Early harvested first cut (EFC timothy silage was fed to five reindeer calves (Rangifer tarandus tarandus L. taken from their natural summer pasture and brought to Tromsø for feeding trial. The calves were housed indoors in metabolism cages and fed EFC timothy silage ad lib. during the trial, which lasted from late November 1994 until the end of February 1995, when animals subsequently were slaughtered. Daily feed intake, gastrointestinal (GI anatomy, body weight and body composition of the animals were examined. Timothy silage {Phleum praténse was harvested 21 June, 1994 in Tromsø, prewilted and stored as round bales containing 97% leaves. The EFC silage contained 42.1% dry matter (DM, and 18.1% crude protein, 20.7% cellulose, 16.9% hemicellulose and 28.0% water soluble carbohydrates (WSC of DM.

All animals except one gained body weight during the trial. The median (range BM at start and at slaughter was 48.5 kg (34.5¬58.0 kg and 50.0 kg (42.0-53.5 kg, respectively. Median (range carcass weight % of BM was 58.0% (51.2-58.7% and muscle index value 0.0132 (0.0106-0.0176. The median reticulo-rumen (RR content wet weight (WW was 4601 g (range 2697-5000 g comprising 9.3% of the BM, and 85.1% of the total gastrointestinal wet weight content. The median (range gastrointestinal tract weight was 14.1% of BM (10.7-16.4%. Based on feed intake during the trial and body composition at slaughtet we conclude that first cut timothy silage is suitable as emergency feed to reindeer, as long as it is harvested in early growth stage with high proportion of leaves.

    Full Text Available El síndrome de Edwards es originado por un desbalance cromosómico representado por una trisomía 18. Alrededor de 95 % de los pacientes corresponden a trisomía completa, donde están presentes múltiples malformaciones en órganos y sistemas. El 5 % restante pertenece a trisomía parcial o mosaicismo, con un fenotipo incompleto por la ausencia de algunas anomalías típicas del síndrome. La inmunodeficiencia es una manifestación poco frecuente del síndrome Edwards. Se presenta el caso de una paciente de 9 meses de edad con trisomía 18 parcial e infecciones severas recurrentes desde la etapa neonatal, asociadas a anemia, linfopenia, trombocitopenia y neutrofilia. La ecografía mostró una hipoplasia del timo. Se encontraron cifras disminuidas de linfocitos TCD4+, CD8+ y de células asesinas naturales. La cuantificación de linfocitos B fue normal. Se hallaron concentraciones normales de inmunoglobulinas séricas IgM e IgG y disminuidas de IgA. Se encontró una disminución de la actividad hemolítica total de la vía clásica del complemento. No se encontraron alteraciones en la función opsonofagocítica. Se diagnosticó una inmunodeficiencia combinada asociada, hecho que demostró la heterogeneidad de la expresión clínica del síndrome Edwards y la relación entre el defecto cromosómico y la formación del sistema inmune en el período intrauterino.Edwards' syndrome is caused by a chromosomal imbalance represented by trisomy 18.

    Full Text Available OBJECTIVE To determine the frequency and types of craniofacial abnormalities observed in patients with trisomy 18 or Edwards syndrome (ES. METHODS This descriptive and retrospective study of a case series included all patients diagnosed with ES in a Clinical Genetics Service of a reference hospital in Southern Brazil from 1975 to 2008. The results of the karyotypic analysis, along with clinical data, were collected from medical records. RESULTS: The sample consisted of 50 patients, of which 66% were female. The median age at first evaluation was 14 days. Regarding the karyotypes, full trisomy of chromosome 18 was the main alteration (90%. Mosaicism was observed in 10%. The main craniofacial abnormalities were: microretrognathia (76%, abnormalities of the ear helix/dysplastic ears (70%, prominent occiput (52%, posteriorly rotated (46% and low set ears (44%, and short palpebral fissures/blepharophimosis (46%. Other uncommon - but relevant - abnormalities included: microtia (18%, orofacial clefts (12%, preauricular tags (10%, facial palsy (4%, encephalocele (4%, absence of external auditory canal (2% and asymmetric face (2%. One patient had an initial suspicion of oculo-auriculo-vertebral spectrum (OAVS or Goldenhar syndrome. CONCLUSIONS: Despite the literature description of a characteristic clinical presentation for ES, craniofacial alterations may be variable among these patients. The OAVS findings in this sample are noteworthy. The association of ES with OAVS has been reported once in the literature.

  2. Edward B. Aveling: the people's Darwin.

    Paylor, Suzanne

    2005-06-01

    By the late-19th century, evolutionary theory, known by most people as Darwinism, had earned a reputation as an atheistic theory that challenged religious orthodoxy. From recent historical work we now know a great deal about how those with religious convictions received Darwinian ideas, and the role that professional scientists played in styling and communicating 'Darwinism' to the wider public and between themselves. However, relatively little is known about how Darwinian ideas were received and used by avowedly irreligious groups, and how these groups set about communicating their own version of Darwinism to a public hungry for cheap and accessible science. The activities of the Secularist Edward Bibbins Aveling, a prolific popularizer of Darwinian ideas in the late-19th century, offer a unique insight into this relatively uncharted territory. His work helped to develop the polemic of popular irreligious groups and imbue Darwinism with overtly atheistic connotations; it also engendered unprecedented support for atheism from the general public, and challenged the monopoly that some professional scientists enjoyed over imparting serious scientific knowledge to them.

    The STS-29 Space Shuttle Discovery mission approaches for a landing at NASA's then Ames-Dryden Flight Research Facility, Edwards AFB, California, early Saturday morning, 18 March 1989. Touchdown was at 6:35:49 a.m. PST and wheel stop was at 6:36:40 a.m. on runway 22. Controllers chose the concrete runway for the landing in order to make tests of braking and nosewheel steering. The STS-29 mission was very successful, completing the launch a Tracking and Data Relay communications satellite, as well as a range of scientific experiments. Discovery's five man crew was led by Commander Michael L. Coats, and included pilot John E. Blaha and mission specialists James P. Bagian, Robert C. Springer, and James F. Buchli. Space Shuttles are the main element of America's Space Transportation System and are used for space research and other space applications. The shuttles are the first vehicles capable of being launched into space and returning to Earth on a routine basis. Space Shuttles are used as orbiting laboratories in which scientists and mission specialists conduct a wide variety of scientific experiments. Crews aboard shuttles place satellites in orbit, rendezvous with satellites to carry out repair missions and return them to space, and retrieve satellites and return them to Earth for refurbishment and reuse. Space Shuttles are true aerospace vehicles. They leave Earth and its atmosphere under rocket power provided by three liquid-propellant main engines with two solid-propellant boosters attached plus an external liquid-fuel tank. After their orbital missions, they streak back through the atmosphere and land like airplanes. The returning shuttles, however, land like gliders, without power and on runways. Other rockets can place heavy payloads into orbit, but, they can only be used once. Space Shuttles are designed to be continually reused. When Space Shuttles are used to transport complete scientific laboratories into space, the laboratories remain inside the payload

    Dual treatment with grass and ragweed sublingual immunotherapy (SLIT) tablets has not been studied. To characterize the safety and tolerability of dual grass and ragweed SLIT-tablet administration. This open-label, multicenter trial (NCT02256553) enrolled North American adults (N = 102) allergic to grass and ragweed. The trial had 3 periods, each of 2 weeks duration. In period 1, subjects received once-daily timothy grass SLIT tablet (2800 bioequivalent allergen unit; Merck, Inc, Kenilworth, NJ/ALK, Hørsholm, Denmark). In period 2, subjects received a short ragweed SLIT tablet (12 Ambrosia artemisiifolia 1-U; Merck/ALK) every morning and a grass SLIT tablet every evening. In period 3, subjects received once-daily grass and ragweed SLIT tablets within 5 minutes (simultaneous intake). The primary end point was the proportion of subjects with 1 or more local swelling events in each period. Secondary end points were the proportion of subjects with 1 or more local adverse events (AEs), that discontinued the treatment because of AEs, and subjects with 1 or more local AEs requiring treatment. No severe swellings, systemic allergic reactions, asthma attacks, or reactions requiring epinephrine were reported. Most (99%) AEs were graded mild to moderate. The proportions of subjects with 1 or more local swelling events were 14%, 22%, and 15% for periods 1, 2, and 3, respectively. For periods 1, 2, and 3, the proportions of subjects with 1 or more local AEs were 71%, 69%, and 56%, respectively; the proportions discontinuing the treatment because of treatment-related AEs were 5%, 1%, and 2%, and the proportions with 1 or more local AEs requiring treatment were 4%, 4%, and 1%. In this trial, a 4-week sequential SLIT-tablet dosing schedule followed by simultaneous intake of timothy grass and ragweed tablets was well tolerated. Copyright © 2015 The Authors.

Median numbers of viable anaerobic bacteria adherent to the plant particles (cells/g wet weight of rumen solids, growing on a habitat simulating medium (M8V, were significantly higher (P = 0.05 in the rumen of reindeer fed lichen (26.5 x 109- 53.0 x 109 and hay (4.0 x 109- 40.5 x 109, compared to reindeer fed silage (1.15 x 109 - 3.25 x 109. Anaerobic bacterial strains (n = 551 from the plant particles obtained from the rumen of the nine reindeer examined, were isolated using an acid swollen cellulose medium (M8SC and tested for their ability to hydrolyse carboxymethyl cellulose (CMC. The proportion of CMC hydrolysing adherent bacteria isolated from M8SC was significantly higher in reindeer fed hay (21.5% compared ro animals fed lichen (5.3% and silage (2.7% (P = 0.05. The CMC hydrolysing bacterial srrains (n=42 isolated from reindeer fed hay where characterised as non-cellulolytic Butyrivibrio fibrisolvens (9.5%, cellulolytic B. fibrisolvens (50.0%, Clostridium sp.

None of the bacterial strains isolated from the rumen solids of reindeer fed lichen or silage were found to be cellulolytic. This study suggests that both lichen and timothy silage have a negative influence, compared to hay, on the numbers of cellulolytic bacteria adherent to the plant particles in the rumen of reindeer.

    2003-12-01

    Harrison Edward ``Harry" Radford, a noted laboratory spectroscopist and pioneer in the application of magnetic resonance techniques to spectroscopy, died on 5 May 2000, after a long battle with amyotropic lateral sclerosis (ALS). During a 37-year career at the National Bureau of Standards and the Smithsonian Astrophysical Observatory, Harry measured the frequencies of numerous molecular transitions which aided the emerging field of astrochemistry. Harry was both an excellent theoretician and a preeminently skilled experimentalist. He has several major spectroscopic achievements to his credit. He performed the first study of a short-lived molecular free radical, OH, by electron paramagnetic resonance spectroscopy, opening up a huge and important field of research. Together with colleagues he made the first observation of the rotational spectrum of CH by far infrared laser magnetic resonance spectroscopy and extended the technique to other molecules such as CH3O. Harry was born in Peterborough, New Hampshire, on 26 July 1927. He was the son of Harrison Edwin Radford, a roofer, and Dorothy (née Cole) Radford. He dropped out of high school to join the Navy in 1944 as an electronics technician's mate. After his discharge in 1946 he worked in the family construction business for four years as a roofer. In 1950 he entered the University of New Hampshire and graduated four years later, Summa Cum Laude, with a degree in physics. As a graduate student at Yale from 1954 to 1959 he wrote his PhD thesis under the supervision of V.W. Hughes on the microwave Zeeman spectra of oxygen and fluorine where he used the technique of paramagnetic resonance absorption in atomic vapors. In 1954 he married Mildred Spofford. They had three daughters, Susan (born in 1955), Amy (1957), and Sarah (1960). In 1974 he married Alfa Goldthwaithe Morrison, who survived him. From 1959 until 1969 Harry worked at the National Bureau of Standards (now the National Institute of Standards and Technology

O segundo tema é a questão nacional, quando o autor aponta os riscos de uma consciência nacional despreparada ou ainda desvirtuada após as lutas de independência e libertação.

  5. Comments on Timothy F. Murphy's 'the afterlife of embryonic persons: what a strange place heaven must be'.

    Science.gov (United States)

    Head, Ivan F

    2012-12-01

    In this issue, Timothy F. Murphy has written a thought-provoking and carefully nuanced article that focuses on the question of a link between a first moment of conception and an end-state beyond death in the resurrection of a human person. He is particularly concerned to probe the theological implications of asserting that the person exists from the moment of conception, and he does so by asking the reader to imagine what kind of resurrected persons would thus populate a heaven filled with, for instance, the resurrected that had in this biotic life lived but a few hours post conception, or had, say, a CV that covered no more than 5 days of cellular replication. By implication, he asks us to imagine a resurrected person whose earthly life lacked memory, consciousness or bodily form, and rather had persisted as a cluster of undifferentiated pluripotent cells. Murphy's candid and fair treatment of these topics is a helpful invitation to some theologians to follow more thoroughly all implications of dogmatically held positions and to consider more thoroughly new ways of thinking of the person as an emergent reality.

    2014-12-01

    Full Text Available The era of the early ‘Abbasid caliphate made an important mark on the history of the world by the event of the Greek translation movement, i.e. the translation of Greek thoughts into the Arabic language. In addition to this development, the era also saw the flourishing of interreligious discourse, in both polemical literatures and religious debates, especially between Christians and Muslims. This article tries to describe how those two historical remarks are correlated under the light of other factors such as politics and religious identity. The earliest debate was happened between caliph al-Mahdi (r. 755-785 CE and a Nestorian Catholicos, Timothy I (728- 823 CE, as the first sample of religious discourses. The second one is the debate between the caliph al-Ma’mun (r. 813-833CE, who arranged many religious debates in his court, with Theodore Abu Qurra (755 – 830 CE, Bishop of Harran. By knowing the motives of the two caliphs who sponsored those events, readers would catch a better picture of the historical contexts of that time.

    Full Text Available The present study aims to investigate the contribution that actor Edward G. Robinson brought to the American film industry, beginning with his iconic role as gangster Little Caesar in Mervyn Le Roy’s 1931 production, and continuing with widely-acclaimed parts in classic film noirs such as Double Indemnity, The Woman in the Window and Scarlet Street. Edward G. Robinson was actually a Romanian Jew, born Emmanuel Goldenberg in Bucharest, in 1893, a relatively little known fact nowadays. By examining his biography, filmography and his best-known, most successful films (mentioned above, I show that Edward G. Robinson was one of classical Hollywood’s most influential actors; for instance, traits of his portrayal of Little Caesar (one of the very first American gangster films can be found in almost all subsequent cinematic gangster figures, from Scarface to Vito Corleone. In the same vein, the doomed noir characters he played in Fritz Lang’s The Woman in the Window and Scarlet Street are still considered by film critics today to be some of the finest, most nuanced examples of noir heroes. Therefore, the main body of my article will be dedicated to a more detailed analysis of these films, while the introductory section will trace his biography and discuss some of his better-known films, such as Confessions of a Nazi Spy and Key Largo. The present study highlights Edward G. Robinson’s merits and impact on the cinema industry, proving that this diminutive Romanian Jew of humble origins was indeed something of a giant during Hollywood’s classical era.

    Full Text Available While “scaling up” is a lively topic in network science and Big Data analysis today, my purpose in this essay is to articulate an alternative problem, that of “scaling down,” which I believe will also require increased attention in coming years. “Scaling down” is the problem of how macro-level features of Big Data affect, shape, and evoke lower-level features and processes. I identify four aspects of this problem: the extent to which findings from studies of Facebook and other Big-Data platforms apply to human behavior at the scale of church suppers and department politics where we spend much of our lives; the extent to which the mathematics of scaling might be consistent with behavioral principles, moving beyond a “universal” theory of networks to the study of variation within and between networks; and how a large social field, including its history and culture, shapes the typical representations, interactions, and strategies at local levels in a text or social network.

    Edward Henry Sieveking, eminent London physician of Victorian times, is best known as the speaker at the historic meeting at which the chairman, Sir Charles Locock, seem to overshadow him in announcing the introduction of bromide--the first effective anti-convulsant. But in fact Sieveking had announced a most important conceptual advance in epileptology--the demise of "essential epilepsy". In addition his book, published soon after and based upon his lecture, is an important historical resumé of Victorian era concepts and management of epilepsy. His important contributions to the understanding and management of this condition are discussed herein.

In winter the DFC digesta wet weight relative to BM in the animals fed FC and RG silage did not differ significantly from the summer values (P>0.05, while in the NP reindeer it was 1.0-1.2% of BM which is significantly greater than in summer (P<0.05. The differences in relative weight of the fermentation chambers between the animals fed FC and RG silage both summer and winter were not reflected in total BM, which was similar in all groups fed silage. This is explained by a significantly lower carcass weight in the animals fed FC silage compared to the animals fed RG silage. Thus, the GI-tract gross anatomy in the silage fed animals seem to be highly affected by the plant structure and composition, and not by the season.

  17. Sexual portraits: Edward Melcarth and homoeroticism in modern American art.

    Griffey, Erin; Reay, Barry

    2012-01-01

    Although one will not find Edward Melcarth (1914-73) in the best recent histories of male homosexuality and American art, he was not always so spectral. Named in Life magazine in 1950 as one of the best young American artists, he exhibited as a painter, draftsman and sculptor and also practised as an illustrator, photographer and designer. His work survives in the Forbes Collection, in the Smithsonian Institution and in the art archives at the Kinsey Institute. We argue that Melcarth’s vision of the erotic was far broader than the traditional categories of sexuality that are perpetuated in art histories of homoeroticism in modern America – and that such a revisioning enables a reinterpretation of some of the better known images of homosexual art.

    2016-10-01

    We present simulations of the one-dimensional Oslo rice pile model in which the critical height at each site is randomly reset after each toppling. We use the fact that the stationary state of this sand-pile model is hyperuniform to reach system of sizes >107 . Most previous simulations were seriously flawed by important finite-size corrections. We find that all critical exponents have values consistent with simple rationals: ν =4/3 for the correlation length exponent, D =9/4 for the fractal dimension of avalanche clusters, and z =10/7 for the dynamical exponent. In addition, we relate the hyperuniformity exponent to the correlation length exponent ν . Finally, we discuss the relationship with the quenched Edwards-Wilkinson model, where we find in particular that the local roughness exponent is αloc=1 .

  19. Filming Critical Female Perspectives: Edward Yang’s The Terrorizers

    2017-04-01

    Full Text Available From his first film—a twenty-minute short, “Expectations” (1982—to his last—a three-hour masterpiece, 'Yi Yi' (2000—Edward Yang, one of the leading figures of the Taiwan New Cinema movement, devoted his career to portraying the impact of neoliberal capitalism on the lives of the citizens of Taipei. Interestingly, Yang’s films often employ female perspectives to criticize Taiwan’s education system and transnational corporations for perpetuating neoliberal capitalism’s ideology of self-fulfillment and upward mobility. This paper draws upon feminist film theory to investigate the ways in which Yang’s third feature, 'The Terrorizers' (1986, utilizes various innovative cinematic languages to engender a multitude of women’s perspectives to expose male voyeurism and ultimately criticize the impact of neoliberal capitalism in Taipei.

    George Edward Post wrote the first flora of the Middle East in English. His other botanical activities are less familiar. In addition to the flora, this paper discusses his teaching, fieldwork, contribution to Bible dictionaries, relations with the Boissier Herbarium in Geneva, establishment of the herbarium, and letters. Those letters are used here for the first time. Post corresponded with botanical luminaries of his day including Autran, Baker, Balfour, Barbey, Boissier, Bornmüller, Carruthers, Denslow, Haussknecht, Hooker, Schweinfurth, Thistleton-Dyer, Torrey, and Winkler. His long-term relationship with the herbarium at Geneva is highlighted. In addition, some of the lesser understood aspects of his life including chaplaincy during the American Civil War, and missionary to Syria are discussed.

  1. Gamma Ray Sterilization of Starr-Edwards Heart Valve Prostheses

    Energy Technology Data Exchange (ETDEWEB)

    Gibbons, J. R. P.; Alladine, M. F. [London Chest Hospital, London (United Kingdom)

    1967-09-15

    Starr-Edwards valves have normally been sterilized by exposure to ethylene oxide or by autoclaving. Patients having a prosthetic valve replacement are known to have a higher incidence of endocarditis in comparison with patients in which no prosthesis has been used. Ethylene oxide will only sterilize the surface of the valve and autoclaving has caused distortion of the polytetrafluorethylene ring. Work has been done on the effect of gamma radiation on the components of these valve prostheses and is given in detail. The bacteriological efficiency, at a total absorbed dose of 2. 5 Mrad, has been established. Thirty valves treated by this method have now been inserted and twelve patients have been examined post-operatively for a period of one to two years. All valves are working normally and there has been no evidence of blood-borne infection or malfunction of the valve. (author)

  2. Migrants and Their Experiences of Time: Edward T. Hall Revisited

    2009-01-01

    Full Text Available In this paper we reassess the scientific heritage of Edward T. HALL and his contribution to the area of intercultural communication. The key objectives of our study are to demonstrate the applicability of HALL's theory of culture to empirical research and to establish its compatibility with other methods. Specifically, we propose that Alfred SCHÜTZ's phenomenology of sociality be taken as an extension to HALL. The connection between HALL and SCHÜTZ is made possible by the mutual emphases on the temporal dimension of culture and the temporal aspects of migration. With these foci we analyze six narratives by two groups of migrants: German and Russian. By combining HALL's theory of the cultural time with SCHÜTZ's phenomenological perspective on time and the Other and then applying them to empirical data, we show the terms in which different cultures experience time.

    1999-01-01

    Crenosoma vulpis is a nematode lungworm that is highly prevalent in the red fox population of Atlantic Canada. Dogs are susceptible to infection with clinical signs consisting primarily of a chronic cough. A recent report of C. vulpis infection in 3 dogs on Prince Edward Island prompted an investigation into the importance of this parasite as a cause of chronic respiratory disease in Island dogs. A general prevalence was determined through the necropsy of dogs euthanized at the local humane society. Lungs were removed and examined for parasites using a lung flush technique. Rectal feces was collected and examined for first-stage larvae using the Baermann technique and zinc sulfate centrifugal flotation. Ten of 310 dogs (3.2%) were positive with 0-35 worms (mean = 11.0 +/- 13.4) recovered. First-stage larvae of C. vulpis were recovered in the rectal feces of the one animal in which no worms were recovered on lung flush. A second survey was conducted examining fecal samples with the Baermann technique from afebrile dogs with presenting signs of chronic cough that had no history of recent anthelmintic treatment and showed no signs of cardiac disease, based on physical examination. Fifteen of 55 dogs examined (27.3%) were definitively diagnosed as C. vulpis-positive. All of the infected dogs were treated with fenbendazole (50 mg/kg body weight, p.o. q24 h for 3-7 days). Clinical signs resolved in all of the dogs and fecal samples were negative 2-4 weeks posttreatment. It was concluded that C. vulpis infection was a significant cause of upper respiratory disease in dogs on Prince Edward Island and should be considered in all dogs with presenting signs of chronic cough.

    1991-06-01

    This report summarizes the preliminary results of geological and geophysical investigations and offshore side scan sonar surveys of the bedrock and unconsolidated sediments in Prince Edward County, Southern Ontario, by the Ontario Geological Survey in 1989. Investigations were focused on deformations in the bedrock and the surficial deposits. Some of these deformations may be neotectonic in origin. Low magnitude seismicity in the Prince Edward County region appears to be spatially related to a major regional fault system that crosses Lake Ontario and consists of the seismically active Clarendon-Linden Fault System in New York State, the Picton-Napanee and Rideau Faults, the Frontenac-Sharbot Lake Terrane Boundary and the assumed Salmon River Fault in Ontario. Detailed observations were made in the Long Point study area and the Mountain View and Picton Quarries. Bedrock structural features were documented, including: joints; normal, reverse and strike strip faults; brittle folds; and Jurassic age ultramafic dyke. Detailed refraction seismic surveys were conducted across a local fault and possible fold structures. Magnetic surveys, conducted in conjunction with the offshore side scan sonar surveys, documented large magnetic anomalies southeast of Point Petre and at the northeast end of Long Reach. Side scan sonar surveys of the lake bottom to the east of Point Petre confirm the presence of pop-ups in that area of the lake bottom which is immediately adjacent to where pop-ups are observed on land. The pop-ups present in the lake bottom have similar orientations to those mapped in the study area

    measured in a faulted area of the Monument Draw trough. Hydraulic conductivity values generally exhibited the same trends as the transmissivity values. Groundwater-quality data and groundwater-level data were used in context with the hydrogeologic framework to assess the chemical characteristics of water from different sources, regional groundwater-flow paths, recharge sources, the mixing of water from different sources, and discharge in the study area. Groundwater-level altitudes generally decrease from southwest to northeast and regional groundwater flow is from areas of recharge south and west to the north and northeast. Four principal sources of recharge to the Edwards-Trinity aquifer were identified: (1) regional flow that originated as recharge northwest of the study area, (2) runoff from the Barilla, Davis, and Glass Mountains, (3) return flow from irrigation, and (4) upwelling from deeper aquifers. Results indicated Edwards-Trinity aquifer water in the study area was dominated by mineralized, regional groundwater flow that most likely recharged during the cooler, wetter climates of the Pleistocene with variable contributions of recent, local recharge. Groundwater generally flows into the down-dip extent of the Edwards-Trinity aquifer where it discharges into overlying or underlying aquifer units, discharges from springs, discharges to the Pecos River, follows a regional flow path east out of the study area, or is withdrawn by groundwater wells. Structural features such as mountains, troughs, and faults play a substantial role in the distribution of recharge, local and regional groundwater flow, spring discharge, and aquifer interaction.

    The Space Shuttle Endeavour concludes mission STS-49 at NASA's Ames-Dryden Flight Research Facility (later redesignated Dryden Flight Research Center), Edwards, California, with a 1:57 p.m. (PDT) landing 16 May on Edward's concrete runway 22. The planned 7-day mission, which began with a launch from Kennedy Space Center, Florida, at 4:41 p.m. (PFT), 7 May, was extended two days to allow extra time to rescue the Intelsat VI satellite and complete Space Station assembly techniques originally planned. After a perfect rendezvous in orbit and numerous attempts to grab the satellite, space walking astronauts Pierre Thuot, Rick Hieb and Tom Akers successfully rescued it by hand on the third space walk with the support of mission specialists Kathy Thornton and Bruce Melnick. The three astronauts, on a record space walk, took hold of the satellite and directed it to the shuttle where a booster motor was attached to launch it to its proper orbit. Commander Dan Brandenstein and Pilot Kevin Chilton brought Endeavours's record setting maiden voyage to a perfect landing at Edwards AFB with the first deployment of a drag chute on a shuttle mission. Space Shuttles are the main element of America's Space Transportation System and are used for space research and other space applications. The shuttles are the first vehicles capable of being launched into space and returning to Earth on a routine basis. Space Shuttles are used as orbiting laboratories in which scientists and mission specialists conduct a wide variety of scientific experiments.

    2011-12-01

    Dr. Edward W. Burke Jr. passed away on June 15, 2011, after suffering a heart attack. Dr. Burke devoted his professional life to the research and teaching of physics and astronomy at King College in Bristol, Tennessee. Edward W. Burke, Jr., was born in Macon, Georgia, on September 16, 1924. He was a Navy veteran, having been commissioned as an ensign in 1944. He served in the Pacific near the end of World War II. He proceeded to complete his undergraduate degree in mathematics from Presbyterian College in 1947 and pursued the M.S. and Ph.D. in physics (1949 and 1954, respectively) at the University of Wisconsin. Under the direction of Professor Julian Mack, his thesis was titled "Isotope Shift in the Spectra of Boron." Although he did research in atomic spectra in the early part of his career, his interest in astronomy and variable stars in particular were his primary interests during his long academic career. Dr. Burke began his illustrious career at King College in 1949. He initiated the astronomy program there in 1950, included constructing a 12.5 inch Newtonian telescope, homemade as was most everything in those days. Many of his students learned about photometry at the Burke Observatory on the college campus. Burke was known for his trips to the Kitt Peak and Lowell observatories accompanied by undergraduate students on his trips, all of which were made by automobile which he preferred over flying. His initial interest in Ap stars later broadened into variable and especially eclipsing binary stars. His motivation was maintained by his desire to have his students experience basic research and to spark their interest in advanced degrees. Numerous students achieved advanced science and medical degrees because of Burke's encouragement and mentoring. In 1959, Dr. Burke was awarded a Fulbright professorship and traveled to Chile where he taught physics for a year in the Engineering School at the University of Chile in Santiago. He worked to establish a physics

  10. W. Edwards Deming, quality analysis, and total behavior management.

    During the past 10 years, the inclusion of the word "quality" in descriptions of production methods, management approaches, educational systems, service system changes, and so forth, has grown exponentially. It appears that no new approach to any problem is likely to be given much consideration today without overt acknowledgment that some improvement in quality must be the outcome. The origins of the importance of quality are primarily rooted in the awakening recognition of the influence of W. Edwards Deming in the post-World War II restoration of Japanese industry. We provide a brief overview of Deming's approach to modernizing management methods and discuss recent criticisms from the field of organizational behavior management that his approach lacks emphasis on the role of reinforcement. We offer a different analysis of Deming's approach and relate its evolution to the contingencies of reinforcement for the behavior of consulting. We also provide an example of problem solving with Deming's approach in a social service setting familiar to many behavior analysts.

    The aim of this paper is to provide comment on Shuttleworth-Edwards' criticism of the general population norms created for the South African adaptation of the WAIS-IV. In her criticism, she states that the norms are not applicable for any groups in South Africa, based on the fact that the norms were not stratified according to quality of education. A discussion of some of the key issues that impact on the creation of general population norms in the South African context is provided. Demographic characteristics such as education level, quality of education, urban and rural demarcations, and home language are all considered. While the utility of within-group norms is not denied, the adoption of these without reference to the general population is not advised. To recommend that practitioners simply dispense with the general population norm without evidence that it creates misclassification or does not function effectively for the intended population lacks scientific merit at the current time. The need for clinical studies and further predictive validity research using the South African adaptation of the WAIS-IV is crucial to demonstrate the continued utility of the test in the South African context. Additional reference groups will improve the amount of comparative information available for clinicians to be able to make better informed decisions for diagnosis, but the general population norms will be an important starting point in this process.

    In patients with aortic stenosis who cannot have surgery, transcatheter aortic valve replacement using the Edwards SAPIEN valve has been shown to improve survival rate and is approved for commercial use in the United States. This study aims to assess the clinical profile, procedural characteristics, and in-hospital complications in patients treated with a commercial SAPIEN valve outside the clinical trial context. We retrospectively analyzed 69 consecutive patients who underwent transcatheter aortic valve replacement with a commercial SAPIEN valve compared with 55 Placement of AoRTic traNscathetER valves (PARTNER) trial patients from cohort B enrolled in the same institution by the same Heart Team. Compared with the commercial group, patients in the PARTNER cohort B had higher mean Society of Thoracic Surgeons score (10 ± 5 vs 9 ± 4, p = 0.04) and a lower rate of peripheral arterial disease (19% vs 44%, p = 0.004). Most patients in the commercial group had the procedure under conscious sedation (83% vs 66%, p = 0.03). Planned surgical cut down for vascular access was rare in the commercial group (1.4% vs 46%, p commercial group (7.2% vs 27%, p = 0.003; 2.9% vs 16%, p = 0.01; and 28% vs 60%, p commercial group. In conclusion, transfemoral commercial use of the Edwards SAPIEN valve for inoperable patients shows similar in-hospital mortality and stroke rates compared with PARTNER cohort B. The refinements in the procedure such as more conscious sedation, experience of the operators, and careful vascular planning in the commercial group led to lesser vascular and bleeding complications and shorter length of stay.

    International Nuclear Information System (INIS)

    McFall, G.H.; Allam, A.

    1989-03-01

    This report summarizes the preliminary results of geological and geophysical investigations of possible neotectonic features in Prince Edward County, southern Ontario, made by the Ontario Geological Survey during 1988. Low magnitude seismic events indicative of contemporary stress relief occurred during 1987-88 near Salmon Point and Consecon (M 2.2). These events were located proximal to a major regional fault system crossing Lake Ontario and consisting of the Clarendon-Linden Fault System in New York State and the Salmon River-Picton fault systems in Ontario. Detailed observations were made of regional jointing orientations (predominantly 60 degrees and 125 degrees), erosion of surficial deposits adjacent to open fractures, a local fault displacement (post-glacially), dome structures located at Point Petre, and dissolution/karst terrains in the eastern part of the study area. Excavations of four pop-up structures indicate that three are classical pop-ups and one is atypical in structure. Level transects were conducted across complex structures in the eastern part of the study area. Detailed refraction seismic and resistivity surveys were conducted on pop-up and fault features. Preliminary results indicate that the Picton Fault is a complex zone of fractures with differing bedrock on each side. The central zone of the East Duck Pond pop-up is fractured and may contain variable amounts of water. Overturned and upright folds in the Consecon Quarry located outside of the primary research area were documented and found to be trending in a west-northwest to northwest direction. This fold orientation is compatible both with a glacial shove origin and with the present stress field orientations. Although glacial shove can produce overturned folds, it cannot form upright folds. A regional, tectonic deformation oriented northeasterly is therefore suggested as the causative mechanism

The planned 14 day mission, which began with a launch from Kennedy Space Center, Florida, at 7:53 a.m. (PDT), October 18, was the second spacelab flight dedicated to life sciences research. Seven Columbia crewmembers performed a series of experiments to gain more knowledge on how the human body adapts to the weightless environment of space. Crewmembers on this flight included: John Blaha, commander; Rick Searfoss, pilot; payload commander Rhea Seddon; mission specialists Bill MacArthur, David Wolf, and Shannon Lucid; and payload specialist Martin Fettman.

    Full Text Available The aquatic Coleoptera (Gyrinidae, Haliplidae, Dytiscidae, Hydrophilidae, Elmidae, Dryopidae, Heteroceridae of Prince Edward Island, Canada is surveyed. Seventy-two species are now known to occur on Prince Edward Island, 26 of which are added to the island's faunal list. Three species, Gyrinus aquiris LeConte, Oulimnius latiusculus (LeConte, and Helichus striatus LeConte, are removed since there are no voucher specimens or published records to substantiate their presence. The name Dineutus horni is designated as an incorrect subsequent spelling of Dineutus hornii Roberts, 1895. The composition of the fauna is briefly discussed, both from regional and zoogeographic perspectives. There is only one introduced species, Helophorus grandis Illiger. Only one third of the aquatic fauna recorded on the neighbouring mainland has been found on Prince Edward Island, perhaps reflecting an island-associated diminution, the paucity of collecting, an area effect, or a combination of all these factors. The island faunas of Prince Edward Island, Cape Breton Island, and insular Newfoundland are compared. Prince Edward Island's is 36% smaller than the others, in contrast with the island's carabid fauna which is almost identical in magnitude with that of Cape Breton. This might reflect dispersal obstacles, the relative paucity of aquatic habitats on the island, or an insufficient collecting effort. Further research would be desirable, both to better discern the composition of the province's fauna, as well as to monitor the health of aquatic ecosystems in relation to anthropogenic activities.

  4. Feyz Kashani and Jonathan Edwards on the Place of Heart in Religious Knowledge

    Full Text Available This essay seeks to summarize and compare the theological ideas of Jonathan Edwards, a western philosopher, with those of Feyz Kashani, an eastern philosopher. The reason for this study is the numerous conjunctions that are seen in their ideas. These include the harmony of heart and reason in respect to belief, the priority of the heart in the reflection of truth, the belief in centrality of the religion of heart, the necessity of divine grace in the flow of religious knowledge, the emphasis on the esoteric side of religion as opposed to the exoteric side, and the importance of a practical approach to religion. Significant differences also exist between their ideas. For instance, Edwards believes that human nature is sinful and corrupted while Feyz does not believe this is true. Furthermore, Feyz interprets the path of heart to be based on reason, while Edwards has a different point of view.

  5. Translational mini-review series on vaccines: The Edward Jenner Museum and the history of vaccination.

    2007-03-01

    Edward Jenner's discovery of vaccination must rank as one of the most important medical advances of all time and is a prominent example of the power of rational enquiry being brought to bear during the Age of Enlightenment in 18th century Europe. In the modern era many millions of lives are saved each year by vaccines that work essentially on the same principles that were established by Edward Jenner more than 200 years ago. His country home in Berkeley, Gloucestershire, is where he carried out his work and where he spent most of his life. The building is now a museum in which the life and times of Jenner are commemorated including not only the discovery of smallpox vaccination but also his other important scientific contributions to natural history and medicine. The trustees of the Edward Jenner museum are committed to promoting the museum as a real and "virtual" educational centre that is both entertaining and informative.

    2014-07-01

    Full Text Available In 1 Timothy 2:11–15 women are forbidden to teach and have authority over men in the church. The ground for this instruction is the creation account in Genesis 2 that asserts the priority of Adam over Eve in the order of creation. The second reason for the instruction is the deception of Eve according to the account of the Fall in Genesis 3. This pericope has elicited arguments between advocates of egalitarianism and complementarianism revolving over the issues of grammar, the context of the Ephesian church with regard to false teachings and the comparison of this text with the other writings of Paul, for those that subscribe to the authorship of Paul. The contention of this article is that verse 15 provides a major clue as to how this text should be understood. In addition, the author’s rhetoric in this text is interrogated with regard to the text’s own internal literary and theological logic. In this regard, the author is found to be inconsistent in his outlook, for the grace that was poured out abundantly on him: a blasphemer, a persecutor and a violent man and on account of his ignorance andunbelief (1 Tm 1:12–16 is apparently, being denied women on account of Eve’s deception.

    Scarce attention has been given to Samuel Taylor Coleridge's engagement with the philosophical theology of Jonathan Edwards, and yet a clear understanding of each thinker's position on determinism and Original Sin is of vital importance if we are understand the lasting significance of their disagreements. There have been a number of studies to take up Coleridge's influence on the American Romantics, but there is no scholarship that has taken into account how the reception of this influence was inflected both by the legacy of Edwards and by the critical response that his theology elicited from Coleridge.

The two representations provide explicit expressions for the stress prior to and after Rouse relaxation of chain stretch......, respectively. The maximum deviations from the exact representations in simple shear, biaxial extension and uniaxial extension are of order 2%. Based on these two representations, we propose a framework for Doi-Edwards models including chain stretch in the memory integral form....

    2014-01-01

    The Edwards-Trinity aquifer is a vital groundwater resource for agricultural, industrial, and public supply uses in the Pecos County region of western Texas. The U.S. Geological Survey completed a comprehensive, integrated analysis of available hydrogeologic data to develop a numerical groundwater-flow model of the Edwards-Trinity and related aquifers in the study area in parts of Brewster, Jeff Davis, Pecos, and Reeves Counties. The active model area covers about 3,400 square miles of the Pecos County region of Texas west of the Pecos River, and its boundaries were defined to include the saturated areas of the Edwards-Trinity aquifer. The model is a five-layer representation of the Pecos Valley, Edwards-Trinity, Dockum, and Rustler aquifers. The Pecos Valley aquifer is referred to as the alluvial layer, and the Edwards-Trinity aquifer is divided into layers representing the Edwards part of the Edwards-Trinity aquifer and the Trinity part of the Edwards-Trinity aquifer, respectively. The calibration period of the simulation extends from 1940 to 2010. Simulated hydraulic heads generally were in good agreement with observed values; 1,684 out of 2,860 (59 percent) of the simulated values were within 25 feet of the observed value. The average root mean square error value of hydraulic head for the Edwards-Trinity aquifer was 34.2 feet, which was approximately 4 percent of the average total observed change in groundwater-level altitude (groundwater level). Simulated spring flow representing Comanche Springs exhibits a pattern similar to observed spring flow. Independent geochemical modeling corroborates results of simulated groundwater flow that indicates groundwater in the Edwards-Trinity aquifer in the Leon-Belding and Fort Stockton areas is a mixture of recharge from the Barilla and Davis Mountains and groundwater that has upwelled from the Rustler aquifer.

  13. Perseus B over Edwards AFB on a Development Flight

    Science.gov (United States)

    1998-01-01

    A long, slender wing and a pusher propeller at the rear characterize the Perseus B remotely-piloted research aircraft, seen here during a test flight in April1998. Perseus B is a remotely piloted aircraft developed as a design-performance testbed under NASA's Environmental Research Aircraft and Sensor Technology (ERAST) project. Perseus is one of several flight vehicles involved in the ERAST project. A piston engine, propeller-powered aircraft, Perseus was designed and built by Aurora Flight Sciences Corporation, Manassas, Virginia. The objectives of Perseus B's ERAST flight tests have been to reach and maintain horizontal flight above altitudes of 60,000 feet and demonstrate the capability to fly missions lasting from 8 to 24 hours, depending on payload and altitude requirements. The Perseus B aircraft established an unofficial altitude record for a single-engine, propeller-driven, remotely piloted aircraft on June 27, 1998. It reached an altitude of 60,280 feet. In 1999, several modifications were made to the Perseus aircraft including engine, avionics, and flight-control-system improvements. These improvements were evaluated in a series of operational readiness and test missions at the Dryden Flight Research Center, Edwards, California. Perseus is a high-wing monoplane with a conventional tail design. Its narrow, straight, high-aspect-ratio wing is mounted atop the fuselage. The aircraft is pusher-designed with the propeller mounted in the rear. This design allows for interchangeable scientific-instrument payloads to be placed in the forward fuselage. The design also allows for unobstructed airflow to the sensors and other devices mounted in the payload compartment. The Perseus B that underwent test and development in 1999 was the third generation of the Perseus design, which began with the Perseus Proof-Of-Concept aircraft. Perseus was initially developed as part of NASA's Small High-Altitude Science Aircraft (SHASA) program, which later evolved into the ERAST

  14. Obituary: Edward R. (Ted) Harrison, 1919-2007

    Science.gov (United States)

    Irvine, William M.; Arny, Thomas T.; Trimble, Virginia

    2007-12-01

    Cosmologist Edward R. (Ted) Harrison, emeritus Distinguished University Professor of Physics and Astronomy at the University of Massachusetts Amherst, died on 29 January 2007 in his retirement city of Tucson, Arizona, where he was adjunct professor at the Steward Observatory, University of Arizona. The cause of death was colon cancer. He is survived by a sister, brother, and daughter. (A son died in 2000.) Perhaps best known for his work on the growth of fluctuations in the expanding universe and his books on cosmology for the dedicated layperson, Ted had extremely broad interests, and he published more than 200 papers in space sciences, plasma physics, high-energy physics, physical chemistry, and, principally, many aspects of astrophysics. He was a Fellow of the American Physical Society, the American Association for the Advancement of Science, the Royal Astronomical Society, and the Institute of Physics (UK). Ted Harrison was born 8 January 1919 in London, England. His parents were Robert Harrison and Daisy Harrison (nee White). His education at Sir John Cass College, London University, was interrupted by the Second World War, during which he served for six years with the British Army in various campaigns, ultimately acting as Radar Adviser to the Northern Area of the Egyptian Army. It was during the latter service that he met his wife Photeni (nee Marangas). Following the War, Ted became a British Civil Servant, at first with the Atomic Energy Research Establishment in Harwell and then at the Rutherford High Energy Laboratory. During this period he acquired the equivalent of university degrees, becoming a graduate, then an Associate, and finally a Fellow of the Institute of Physics. His somewhat unorthodox education may have contributed to his broad interests and his very intuitive and physical approach to scientific problems. The latter became the bane of generations of graduate students, who might find themselves asked on their physics qualifying exams to

    Fructans can act as cryoprotectants and contribute to freezing tolerance in plant species, such as in members of the grass subfamily Pooideae that includes Triticeae species and forage grasses. To elucidate the relationship of freezing tolerance, carbohydrate composition and degree of polymerization (DP) of fructans, we generated transgenic plants in the model grass species Brachypodium distachyon that expressed cDNAs for sucrose:fructan 6-fructosyltransferases (6-SFTs) with different enzymatic properties: one cDNA encoded PpFT1 from timothy grass (Phleum pratense), an enzyme that produces high-DP levans; a second cDNA encoded wft1 from wheat (Triticum aestivum), an enzyme that produces low-DP levans. Transgenic lines expressing PpFT1 and wft1 showed retarded growth; this effect was particularly notable in the PpFT1 transgenic lines. When grown at 22 °C, both types of transgenic line showed little or no accumulation of fructans. However, after a cold treatment, wft1 transgenic plants accumulated fructans with DP = 3-40, whereas PpFT1 transgenic plants accumulated fructans with higher DPs (20 to the separation limit). The different compositions of the accumulated fructans in the two types of transgenic line were correlated with the differences in the enzymatic properties of the overexpressed 6-SFTs. Transgenic lines expressing PpFT1 accumulated greater amounts of mono- and disaccharides than wild type and wft1 expressing lines. Examination of leaf blades showed that after cold acclimation, PpFT1 overexpression increased tolerance to freezing; by contrast, the freezing tolerance of the wft1 expressing lines was the same as that of wild type plants. These results provide new insights into the relationship of the composition of water-soluble carbohydrates and the DP of fructans to freezing tolerance in plants.

  3. Dynamic data analysis of climate and recharge conditions over time in the Edwards Aquifer, Texas

    Pierce, S. A.; Collins, J.; Banner, J.

    2017-12-01

    Understanding the temporal patterns in datasets related to climate, recharge, and water resource conditions is important for informing water management and policy decisions. Data analysis and pipelines for evaluating these disparate sources of information are challenging to set up and rely on emerging informatics tools to complete. This project gathers data from both historical and recent sources for the Edwards Aquifer of central Texas. The Edwards faces a unique array of challenges, as it is composed of karst limestone, is susceptible to contaminants and climate change, and is expected to supply water for a rapidly growing population. Given these challenges, new approaches to integrating data will be particularly important. Case study data from the Edwards is used to evaluate aquifer and hydrologic system conditions over time as well as to discover patterns and possible relationships across the information sources. Prior research that evaluated trends in discharge and recharge of the aquifer is revisited by considering new data from 1992-2015, and the sustainability of the Edwards as a water resource within the more recent time period is addressed. Reusable and shareable analytical data pipelines are constructed using Jupyter Notebooks and Python libraries, and an interactive visualization is implemented with the information. In addition to the data sources that are utilized for the water balance analyses, the Global Surface Water Monitoring System from the University of Minnesota, a tool that integrates a wide number of satellite datasets with known surface water dynamics and machine learning, is used to evaluate water body persistence and change over time at regional scales. Preliminary results indicate that surface water body over the Edwards with differing aerial extents are declining, excepting some dam-controlled lakes in the region. Other existing tools and machine learning applications are also considered. Results are useful to the Texas Water Research

  4. Second sector cool down

    2007-01-01

    At the beginning of July, cool-down is starting in the second LHC sector, sector 4-5. The cool down of sector 4-5 may occasionally generate mist at Point 4, like that produced last January (photo) during the cool-down of sector 7-8.Things are getting colder in the LHC. Sector 7-8 has been kept at 1.9 K for three weeks with excellent stability (see Bulletin No. 16-17 of 16 April 2007). The electrical tests in this sector have got opt to a successful start. At the beginning of July the cryogenic teams started to cool a second sector, sector 4-5. At Point 4 in Echenevex, where one of the LHC’s cryogenic plants is located, preparations for the first phase of the cool-down are underway. During this phase, the sector will first be cooled to 80 K (-193°C), the temperature of liquid nitrogen. As for the first sector, 1200 tonnes of liquid nitrogen will be used for the cool-down. In fact, the nitrogen circulates only at the surface in the ...

  5. The final cool down

    CERN Multimedia

    Thursday 29th May, the cool-down of the final sector (sector 4-5) of LHC has begun, one week after the start of the cool-down of sector 1-2. It will take five weeks for the sectors to be cooled from room temperature to 5 K and a further two weeks to complete the cool down to 1.9 K and the commissioning of cryogenic instrumentation, as well as to fine tune the cryogenic plants and the cooling loops of cryostats.Nearly a year and half has passed since sector 7-8 was cooled for the first time in January 2007. For Laurent Tavian, AT/CRG Group Leader, reaching the final phase of the cool down is an important milestone, confirming the basic design of the cryogenic system and the ability to operate complete sectors. “All the sectors have to operate at the same time otherwise we cannot inject the beam into the machine. The stability and reliability of the cryogenic system and its utilities are now very important. That will be the new challenge for the coming months,” he explains. The status of the cool down of ...

    WTI fell below $70/bbl in early June on reports that Iran was considering a proposal from the EU and the UN to resolve the dispute over Tehran's plans to develop nuclear power. Sellers took further encouragement from the news that the Iraqi leader of al-Qaida, Abu Musab al-Zarqawi, had been killed. July WTI futures went down as far as $69.10/bbl. The euphoria proved to be short-lived. Within a short time, Iran announced that it was to resume the enrichment of uranium, whilst in Iraq, there was no sign whatever that the killing of one terrorist leader was going to bring about peace there. During the month of June, an estimated 1,500 people were killed in Baghdad alone. Attacks on road tankers caused the suspension of exports of heavy fuel oil, which is produced to excess by Iraq's refining industry. Lacking anywhere to store the surplus fuel oil, the government ordered what were described as 'large quantities' to be incinerated. The one piece of good news from Iraq was the reopening of the export pipeline from Kirkuk to Ceyhan for the first time since January. Throughput was reported in late June at 325,000 bpd. Even here, though, the situation was not entirely without its troubles. The state marketing company, SOMO, received disappointing bids for the oil it was offering for sale at Ceyhan. (author)

    In this issue of Reproductive BioMedicine Online, Benagiano, Carrara and Filippi have produced a clearly written and comprehensive account of why the Roman Catholic Church has not welcomed the award of the 2010 Nobel Prize in Physiology and Medicine to Dr Robert G Edwards for the development of human IVF. I commend the article for its clarity and lucidity but attempt to point out some areas where disagreement even with its nuanced opposition to IVF may be legitimate. I try to make some simple comments that explain why this is so and I suggest some areas to which contemporary theology and philosophy can commit itself. But it is good to see even a nuanced response to the work of Robert G Edwards rather than a blanket condemnation. Copyright © 2011 Reproductive Healthcare Ltd. Published by Elsevier Ltd.

    The objective of this study was to investigate the effects of changing forage source in dairy cow diets from timothy silage (TS) to alfalfa silage (AS) on enteric CH₄ emissions, ruminal fermentation characteristics, digestion, milk production, and N balance. Nine ruminally cannulated lactating cows were used in a replicated 3 × 3 Latin square design (32-d period) and fed (ad libitum) a total mixed ration (TMR; forage:concentrate ratio of 60:40, dry matter basis), with the forage portion consisting of either TS (0% AS; 0% AS and 54.4% TS in the TMR), a 50:50 mixture of both silages (50% AS; 27.2% AS and 27.2% TS in the TMR), or AS (100% AS; 54.4% AS and 0% TS in the TMR). Compared with TS, AS contained less (36.9 vs. 52.1%) neutral detergent fiber but more (20.5 vs. 13.6%) crude protein (CP). In sacco 24-h ruminal degradability of organic matter (OM) was higher for AS than for TS (73.5 vs. 66.9%). Replacement of TS with AS in the diet entailed increasing proportions of corn grain and bypass protein supplement at the expense of soybean meal. As the dietary proportion of AS increased, CP and starch concentrations increased, whereas fiber content declined in the TMR. Dry matter intake increased linearly with increasing AS proportions in the diet. Apparent total-tract digestibility of OM and gross energy remained unaffected, whereas CP digestibility increased linearly and that of fiber decreased linearly with increasing inclusion of AS in the diet. The acetate-to-propionate ratio was not affected, whereas ruminal concentration of ammonia (NH₃) and molar proportion of branched-chain VFA increased as the proportion of AS in the diet increased. Daily CH₄ emissions tended to increase (476, 483, and 491 g/d for cows fed 0% AS, 50% AS, and 100% AS, respectively) linearly as cows were fed increasing proportions of AS. Methane production adjusted for dry matter intake (average=19.8 g/kg) or gross energy intake (average=5.83%) was not affected by increasing AS inclusion

It has also been specifically asked to comment on 'the desirability of the Department of Mines and Energy having prime responsibility for environmental matters in relation to mining operations'. This report begins with a description of the Olympic Dam operations near Roxby Downs and with a brief overview of the regulations controlling those operations. The site of the leakage the Olympic Dam tailings retention system is then described in greater detail. Part 3 describes how the system was originally designed, modified and approved. It ends with a series of findings about the adequacy of the original design (including the monitoring systems built into it) and of the approvals process. Recommendations are then made about how future approvals should be handled. Part 4 of the report outlines how the tailings retention system was built and operated and how the massive leakage from it was detected and reported. Findings about the adequacy of the management of the system and about the initial reactions to the leakage are then made, together with recommendations designed to improve future management of the system. 25 refs., 15 figs

    The first French transapical transcatheter aortic valve implantation (TAVI) was performed in July 2007 in our department. To report 4-year outcomes of transapical implantation with the Edwards transcatheter bioprosthesis. We prospectively evaluated consecutive patients who underwent transapical implantation with an Edwards transcatheter bioprosthesis between July 2007 and October 2011. Patients were not suitable for conventional surgery (due to severe comorbidities) or transfemoral implantation (due to poor femoral access). Among 61 patients (59.0% men), mean logistic EuroSCORE was 27.5 ± 14.9% and mean age was 81.0 ± 6.8 years. Successful valve implantation was achieved in 59/61 patients (96.7%) of patients. The other two patients required conversion to conventional surgery due to prosthesis embolization and died. Six additional patients died in the postoperative period. Causes of perioperative death were two septic shocks (one of peritonitis), two multi-organ failure, one ventricular fibrillation and one respiratory insufficiency. Intraprocedural stroke was not observed in any patient. The actuarial survival rates at 1, 2 and 4 years were 73.8%, 67.2% and 41.0%. During this 4-year period, four patients died of cardiovascular events, but no impairment of transprosthesis gradient was observed. Our series of 61 patients who underwent transapical implantation of the Edwards transcatheter bioprosthesis shows satisfactory results, similar to other reports, considering the high level of severity of patients referred for this method. Transapical access is a reliable alternative method for patients that cannot benefit from a transfemoral approach. Copyright © 2012. Published by Elsevier Masson SAS.

    Full Text Available Education is always regarded as a necessary factor of social development. One of the positive means to solve urgent problems in the field of professional education is not only systematization of the information, but also the creative accumulation and assimilation of the cultural experience and, as a result, of the scientific, artistic-design, project-constructive and/or technological principles of activities. The high standards to the future teachers’ professional education are caused by the binary character of the future activities: the teacher should be both a professional and a pedagogue. The transformation of the professional education, while there are lots of global challenges in the world, leads to the activation of the creative potential of the future pedagogue at a professional educational institution. The goal of this article is to analyze systems of thinking suggested by Edward de Bono, and to attempt implementing partially these approaches into strategic thinking in the field of professional education, i.e. in the future teachers’ sewing specialization at a professional educational institution. According to the goal of the article, the whole complex of scientific approaches and methods has been used at the different theoretical and empirical levels. The systemic approach is in the core of the research, following the idea of the integrity of thinking expressed by Edward de Bono and of mechanisms which facilitate it. At the moment in our volatile world there is a clear need in new type of thinking – creative and constructive, which allows to form new ideas and ways for development. The system of such a kind of thinking was developed by Edward de Bono. According to him, the main method for the process of problem solving should be: refusal from cliché and established patters of thinking; perception of the problem with humor; continuous questioning of permissiveness; change in the way of seeking for information; creation of integral

  9. Pain in Down's Syndrome

    Directory of Open Access Journals (Sweden)

    Federica Mafrica

    2006-01-01

    Full Text Available Pain is a homeostatic mechanism that intervenes to protect the organism from harmful stimuli that could damage its integrity. It is made up of two components: the sensory-discriminative component, which identifies the provenance and characteristics of the type of pain; and the affective-motivational component, on which emotional reflexes, following the painful sensation, depend.There is a system for pain control at an encephalic and spinal level, principally made up of the periaqueductal grey matter, the periventricular area, the nucleus raphe magnus, and the pain-inhibition complex situated in the posterior horns of the spinal cord. Through the activation of these pain-control systems, the nervous system suppresses the afference of pain signals. Endogenous opioids represent another analgesic system.In the course of various studies on pain transmission in Down patients, the reduced tolerance of pain and the incapacity to give a qualitative and quantitative description emerged in a powerful way. All of these aspects cause difficulty in evaluating pain. This is linked to several learning difficulties. However, it cannot be excluded that in these anomalies of pain perception, both the anatomical and the neurotransmitter alteration, typical of this syndrome, may hold a certain importance.This fact may have important clinical repercussions that could affect the choice of therapeutic and rehabilitative schemes for treatment of pathologies in which pain is the dominant symptom, such as postoperative pain. It could influence research on analgesics that are more suitable for these patients, the evaluation of the depth of analgesia during surgical operation, and ultimately, absence of obvious pain manifestations. In conclusion, alterations of the central nervous system, neurotransmitters, pain transmission, and all related problems should be considered in the management of pain in patients with Down's syndrome, especially by algologists and

    As youth struggle with anxiety and depression, promoting positive mental fitness is a primary concern. Canadian school-based mental health programs that focus on positive psychology and positive mental health initiatives emphasize safe and supportive environments, student engagement, resilience, and self-determination. This study examined predictors of mental fitness and its 3 components (autonomy, competence, and relatedness). School Health Action Planning and Evaluation System-Prince Edward Island (SHAPES-PEI) and the New Brunswick Student Wellness Survey (NB SWS) are data collection and feedback systems that survey youth about 4 health behaviors. Grade 7-12 students in Prince Edward Island (N = 3318) and New Brunswick (N = 7314) completed a mental fitness questionnaire in 2008-2009 (PEI) and 2006-2007 (NB). Four linear regression models were conducted to examine student characteristics associated with mental fitness, autonomy, competence, and relatedness. Positive associations were found between school connectedness (p fitness, as well as autonomy, competence, and relatedness. There were also significant relationships between affect, pro-social and antisocial behaviors, tried smoking, and mental fitness.

    A 4-6-mo-old female red fox (Vulpes vulpes) was presented to the Atlantic Veterinary College (AVC) Teaching Hospital, Prince Edward Island, Canada. On presentation, the fox was weak and had pale mucous membranes. A complete blood count and a serum biochemistry profile were performed. Blood smear examination revealed low numbers of erythrocytes containing centrally to paracentrally located, single, rarely multiple, approximately 1 x 2 microm, oval to round organisms with morphology similar to Babesia microti. Polymerase chain reaction testing and DNA sequencing of the Babesia species 18S rRNA gene were performed on DNA extracted from whole blood. Results were positive for a Babesia microti-like parasite genetically identical to Babesia (Theileria) annae. The fox was euthanized due to poor prognosis for recovery. Necropsy examination revealed multifocal to locally extensive subacute nonsuppurative meningoencephalitis, an eosinophilic broncho-pneumonia, a moderate diffuse vacuolar hepatopathy, and lesions associated with blunt trauma to the left abdominal region. This is the first reported case of a red fox in Canada infected with a piroplasm. It remains uncertain whether the presence of this hemoparasite in this fox was pathogenic or an incidental finding. The potential for competent vectors of Babesia species on Prince Edward Island, the potential for this Babesia microti-like parasite to infect other wild and domestic canids, and the significance of this parasite to the health of infected individuals are yet to be determined.

Hence, special attention is given to Said’s interpretation of novels as constructions of the geopolitical reality: i.e. the characteristics of “imperialism” are examined as found in such English and French writers as Jane Austen, Rudyard Kipling, Joseph Conrad and Albert Camus, illustrating the way how novels as an aesthetic form participated in the “cultural construction” of colonialism. In the next part of the discussion, the paper presents another main topic of Edward Said that reveals how “cultural imperialism”, “orientalism” and “covering Islam” are still, unfortunately, current topics. Special attention is given to Said's demystification of the opposition between “us” and “them”, or “the West” and “Others”, through the example of the relationship between “the West” and “Islam”. Behind this issue, unequal power relations exist, as well as unequal relations of power and knowledge; “anti-systemic movements”, especially, and the “post-colonial discourse”, in general, warns us of this.

  15. “Sex and the Island”: Lives of Single Women in Prince Edward Island

    Full Text Available This article considers the significance attributed to Prince Edward Island in managing a marginalized single female identity, as presented by accounts of thirty never-married and previously-married Island women, aged twenty-seven through sixty-five. As popular media and social narratives overwhelmingly position contemporary single women against an urban backdrop, the question arises as to whether unmarried Island women feel “marooned” in ways their urban counterparts may not. In accordance with feminist aims to produce research for, rather than about, women’s lives, the paper focuses on two themes from fieldwork interviews that were of particular interest to participants. The first theme relates to negotiating female singleness within the Island’s family-centered culture, and the second theme presents participants’ talk around advantages and disadvantages of living in Prince Edward Island, Canada, as single women. The paper concludes with a summary of other findings from the study and suggestions for future research on female singleness and island locales.

    Malcolm B. Dockerty and Lewis B. Woolner, 2 preeminent mid-20th-century surgical pathologists, spent their entire careers at the Mayo Clinic. Both were raised in poverty on potato farms only 49 miles apart in Canada's smallest province (Prince Edward Island); both were educated in 1-room schools and graduated as gold medalists from Prince Edward Island's only college and then from Maritime Canada's only medical school; both then trained at the Mayo Clinic. To explore the lives and accomplishments of these 2 important surgical pathologists. Standard historiographic methods were used to explore primary and secondary historical sources. Both became world-renowned general surgical pathologists, one developing subspecialty expertise in gynecologic pathology and the other in cytopathology, pulmonary pathology, and thyroid/parathyroid pathology. Both were prolific authors with h-indices higher than 40, and between them, they published more than 750 peer-reviewed papers and book chapters. As educators, they trained hundreds of pathology and surgery residents/fellows who disseminated their knowledge around the world. Both were fascinated by poetry from childhood and could quote the classics from memory. One wrote poetry throughout his entire life and even used it to teach pathology and serve as his memoir; the other strongly preferred the classics and in jest called his colleague "a (minor) poet." Both received postretirement honorary doctorates from their alma maters. Dockerty died in 1987; Woolner celebrates his 100th birthday on November 17, 2013. Every pathologist should know of these 2 pioneering surgical pathologists.

    2016-02-01

    Full Text Available The post-world war II American social and cultural setting was ambiguously featured with enforced conformity in the name of prosperity and Americanization of the nation. Despite of this fact, American writers, especially, dramatists conveyed their message against this fixation through variety and intellectuality. Edward Albee’s The Zoo Story is one of those literary assets which dedicatedly cut through the illusions of contemporary American social and cultural ethos. Here, his characters are seen struggling constantly with their insecurities and existential angst in the society. He presents America, the so-called ‘Land of Free and Home of Braves’ (note 1, in such a portrayal that unveils the traps of cages and confinement underneath. The target of this paper is to trace Edward Albee’s heightened awareness about the post-war American socio-cultural reality evident in The Zoo Story. It also looks for the voice in which the text echoes out the anti-communist, materialistic, gender-coded boundaries, coupled with paradoxical media representations, religious bordering and how Albee challenges these issues with an anti-establishment tone. Keywords: subversive culture, anti-communism, media, religion and homosexuality

    2004-01-01

    An extensive investigation at the Camp Edwards, Massachusetts Military Reservation (MMR) demonstrates that assessment of groundwater and soil contamination at military ranges can be limited primarily to explosive-related compounds such as RDX, HMX, perchlorate, TNT and their transformation products. A modified analytical method is recommended to expand the list of explosives and to improve the detection limits. Analyses of metals, VOCs, SVOCs, and TICs are unnecessary. Soil samples may require the analyses of PAHs and PCNs for burn areas. Camp Edwards, as one of the few military ranges that have been exhaustively investigated for contaminants, is an ideal point of departure for evaluating other ranges. The permeable site soils promote leaching of contaminants and inhibit biotic and abiotic transformations. Moreover, the site has experienced an unusual extent of activities in its more than ninety years of active use. The recommendations in this report are based on data obtained for more than 200 analytes from more than 15,000 environmental samples. - Assessment of groundwater and soil contamination at US military ranges can be limited primarily to explosive-related compounds

  19. The Italian Job: Giambattista Vico at the Origin of Edward Said’s Humanism

    2016-08-01

    Full Text Available The aim of this paper is twofold. First, it will try to clarify the importance of the Italian philosopher Giambattista Vico (1668-1744 in shaping Edward Said’s categories. Second, it will shed light on the theoretical importance of such genealogy. From the philological point of view, it is important to show how profound Said’s knowledge of Vico’s work is. Therefore, this paper will follow references to Vico within the whole of Said’s work, from late the sixties ones to the posthumous Humanism and Democratic Criticism. As far as theory is concerned, understanding Said’s use of Vico’s concepts explains why Said refers to his own work with the controversial term “humanism.” Vico, critiquing modernity from the onset, is the basis on which Said built a new critical humanism. In particular, Said uses the very essential elements of the philosophy of Vico: the importance of body as the source of humanity, the critique of modern abstractions, the idea that man knows what he makes, and the idea of the historicity of every human invention and construction.   Keywords: Edward Said; Vico; Humanism; Modernity; Historicity; Facticity.

  20. Bed-material entrainment and associated transportation infrastructure problems in streams of the Edwards Plateau, central Texas

    The Texas Department of Transportation commonly builds and maintains low-water crossings (LWCs) over streams in the Edwards Plateau in Central Texas. LWCs are low-height structures, typically constructed of concrete and asphalt, that provide acceptable passage over seasonal rivers or streams with relatively low normal-depth flow. They are designed to accommodate flow by roadway overtopping during high-flow events. The streams of the Edwards Plateau are characterized by cobble- and gravel-sized bed material and highly variable flow regimes. Low base flows that occur most of the time occasionally are interrupted by severe floods. The floods entrain and transport substantial loads of bed material in the stream channels. As a result, LWCs over streams in the Edwards Plateau are bombarded and abraded by bed material during floods and periodically must be maintained or even replaced.

  1. Pinning down the axion

    Davis has argued that, without inflation, the decay of axionic strings is the primary source of axions. This implies a cosmological lower bound on the axion mass of 10 -5 to 10 -3 eV. In order to obtain a sharper bound it is essential to know the spectrum of emitted axions and the detailed motion of a global string strongly coupled to the axionic field. To this end, we obtain self-consistent, renormalized equations that describe the dynamics of a radiating global string interacting with its surrounding axionic field. We describe the numerical formalism for evolving string trajectories using these equations. From the numerical and analytical evidence we argue that, with appropriate renormalization, the motion of an interacting cosmic string loop can be well approximated by the motion of a free Nambu-Goto string. This implies a lower bound for the axion mass of 10 -3 eV. Together with the recent upper bound of 4x10 -4 eV from the supernova SN1987a, this marginally rules out the invisible axion, or at least pins down the axion mass to a very narrow window around 10 -3 eV. This still leaves open the window around 2 eV for hardronic axions, but in that case the axion is no longer a serious dark matter candidate. (orig.)

  2. Geologic framework and hydrogeologic characteristics of the outcrops of the Edwards and Trinity aquifers, Medina Lake area, Texas

    Small, Ted A.; Lambert, Rebecca B.

    1998-01-01

    The hydrogeologic subdivisions of the Edwards aquifer outcrop in the Medina Lake area in Medina and Bandera Counties generally are porous and permeable. The most porous and permeable appear to be hydrogeologic subdivision VI, the Kirschberg evaporite member of the Kainer Formation; and hydrogeologic subdivision III, the leached and collapsed members, undivided, of the Person Formation. The porosity of the rocks in the Edwards aquifer outcrop is related to depositional or diagenetic elements along specific stratigraphic horizons (fabric selective) and to dissolution and structural elements that can occur in any lithostratigraphic horizon (not fabric selective). Permeability depends on the physical properties of the rock such as size, shape, and distribution of pores.

    Many karst regions are undergoing rapid population growth and expansion of urban land accompanied by increases in wastewater generation and changing patterns of nitrate (NO{sub 3}{sup −}) loading to surface and groundwater. We investigate variability and sources of NO{sub 3}{sup −} in a regional karst aquifer system, the Edwards aquifer of central Texas. Samples from streams recharging the aquifer, groundwater wells, and springs were collected during 2008–12 from the Barton Springs and San Antonio segments of the Edwards aquifer and analyzed for nitrogen (N) species concentrations and NO{sub 3}{sup −} stable isotopes (δ{sup 15}N and δ{sup 18}O). These data were augmented by historical data collected from 1937 to 2007. NO{sub 3}{sup −} concentrations and discharge data indicate that short-term variability (days to months) in groundwater NO{sub 3}{sup −} concentrations in the Barton Springs segment is controlled by occurrence of individual storms and multi-annual wet-dry cycles, whereas the lack of short-term variability in groundwater in the San Antonio segment indicates the dominance of transport along regional flow paths. In both segments, longer-term increases (years to decades) in NO{sub 3}{sup −} concentrations cannot be attributed to hydrologic conditions; rather, isotopic ratios and land-use change indicate that septic systems and land application of treated wastewater might be the source of increased loading of NO{sub 3}{sup −}. These results highlight the vulnerability of karst aquifers to NO{sub 3}{sup −} contamination from urban wastewater. An analysis of N-species loading in recharge and discharge for the Barton Springs segment during 2008–10 indicates an overall mass balance in total N, but recharge contains higher concentrations of organic N and lower concentrations of NO{sub 3}{sup −} than does discharge, consistent with nitrification of organic N within the aquifer and consumption of dissolved oxygen.

    The Edwards-Trinity aquifer system underlies about 42,000 square miles of west-central Texas. Nearly flat-lying, mostly Comanche (Lower Cretaceous) strata of the aquifer system thin northwestward atop massive pre-Cretaceous rocks that are comparatively impermeable and structurally complex. From predominately terrigenous clastic sediments in the east and fluvialdeltaic (terrestrial) deposits in the west, the rocks of early Trinitian age grade upward into supratidal evaporitic and dolomitic strata, intertidal limestone and dolostone, and shallow-marine, openshelf, and reefal strata of late Trinitian, Fredericksburgian, and Washitan age. A thick, downfaulted remnant of mostly open-marine strata of Eaglefordian through Navarroan age composes a small, southeastern part of the aquifer system.

    The late eighteenth and early nineteenth centuries were a period of particular innovation in the history of British psychiatry. Enlightenment ideas brought a change in attitudes to insanity, reflected in the growing prevalence of psychologically based treatment techniques being implemented in both public and private institutions. A new group of practitioners, specializing in the treatment and management of insanity, was emerging. One of the most prominent and successful was Dr. Edward Long Fox, a Bristol physician. His main venture was the establishment of Brislington House in 1806. Here he created a state-of-the-art asylum, catering mainly for the wealthier members of society. Its unique design, with seven distinct houses, enabled classification of patients according to social class as well as behavioural presentation. Within a context of safety and security, Fox sought to provide a therapeutic regime based on the principles and practices of moral management.

    Anderson, Thomas R; Rice, Tony

    2006-12-01

    While dredging in the Aegean Sea during the mid-19th century, Manxman Edward Forbes noticed that plants and animals became progressively more impoverished the greater the depth they were from the surface of the water. By extrapolation Forbes proposed his now infamous azoic hypothesis, namely that life would be extinguished altogether in the murky depths of the deep ocean. The whole idea seemed so entirely logical given the enormous pressure, cold and eternal darkness of this apparently uninhabitable environment. Yet we now know that the sea floor is teeming with life. Curiously, it took 25 years for the azoic hypothesis to fall from grace. This was despite the presence of ample contrary evidence, including starfishes, worms and other organisms that seemingly originated from the deep seabed. This is a tale of scientists ignoring observations that ran counter to their deep-seated, yet entirely erroneous, beliefs.

    Analyses of samples collected from Barton Springs at approximately weekly Intervals and from Barton Creek and five wells in the Austin area during selected storm-runoff periods generally show that recharge during storm runoff resulted in significant temporal and area! variations in the quality of ground water in the recharge zone of the Edwards aquifer. Recharge during storm runoff resulted in significant increases of bacterial densities in the ground water. Densities of fecal coliform bacteria in samples collected from Barton Springs, the major point of ground-water discharge, ranged from less than 1 colony per 100 milliliters during dry weather in November 1981 and January and August 1982 to 6,100 colonies per 100 milliliters during a storm in May 1982. Densities of fecal streptococcal bacteria ranged from 1 colony per 100 miniliters during dry weather in December 1981 to 11,000 colonies per 100 miniliters during a storm in May 1982.

    A Carpentier-Edwards pericardial (CEP) bioprosthesis was explanted from an 81-year-old woman due to nonstructural dysfunction 9 years after mitral valve replacement. The nonstructural dysfunction produced severe regurgitation in the mitral position. During the surgery, excessive pannus overgrowth was seen on the left ventricular side of the CEP bioprosthesis. Pannus overgrowth was prominent on one leaflet. That leaflet was stiff and shortened due to the excessive overgrowth of pannus. In this patient, the distortion of one leaflet was the main reason for transvalvular leakage of the CEP bioprosthesis in the mitral position. A new CEP bioprosthesis was implanted in the mitral position. Pathological analysis revealed fibrotic pannus with a small amount of cellular material over the leaflets of the resected CEP valve. This change was marked on the distorted leaflet.

    2000-06-01

    The philosophy of primary health care (PHC) recognizes that health is a product of individual, social, economic, and political factors and that people have a right and a duty, individually and collectively, to participate in the course of their own health. The majority of nursing models cast the client in a dependent role and do not conceptualize health in a social, economic, and political context. The Prince Edward Island Conceptual Model for Nursing is congruent with the international move towards PHC. It guides the nurse in practising in the social and political environment in which nursing and health care take place. This model features a nurse/client partnership, the goal being to encourage clients to act on their own behalf. The conceptualization of the environment as the collective influence of the determinants of health gives both nurse and client a prominent position in the sociopolitical arena of health and health care.

    Ninety-six feral cats from Prince Edward Island were used to determine the prevalence of selected infectious agents. The prevalence rates were 5.2% for feline immunodeficiency virus, 3.1% for feline leukemia virus, 3.1% for Mycoplasma haemofelis, 8.4% for Candidatus Mycoplasma haemominutum, 2.1% for Bartonella spp. and 29.8% for exposure to Toxoplasma gondii. Oocysts of T. gondii were detected in 1.3% of the fecal samples that were collected. Gender and retroviral status of the cats were significantly correlated with hemoplasma infections. Use of a flea comb showed that 9.6% of the cats had fleas; however, flea infestation was not associated with any of the infectious agents. PMID:22379197

    2011-01-01

    In 1894, the Polish neurologist Edward Flatau (1868-1932), working in Berlin, published an exquisite photographic atlas of the unfixed human brain, preceding by 2 years Das Menschenhirn, the reference work of Gustaf Retzius (1842-1919) in Stockholm. In his early career as a neuroanatomist and neurologist, Sigmund Freud (1856-1939) wrote a review of Flatau's atlas for the Internationale klinische Rundschau, which has not been included in the 'Standard Edition of the Complete Psychological Works'. The aim of the present paper is twofold: to document Freud's review, and to revive the largely forgotten atlas of Flatau. The full text of Freud is presented in translation. Further, one element Flatau, Retzius and Freud had in common is discussed: their early role as protagonists and firm supporters of Ramón y Cajal's neuron theory, the cornerstone of modern neuroscience.

    Thank you, Jean Bernard Minster and those who supported my nomination for the Edward A. Flinn III Award. We owe so much to colleagues such as Bernard Minster who support NASA and Earth Science with unrelenting and unselfish service. I am also grateful to my parents, the people of Lewiston, Maine, and the National Defense Education Act (NDEA) of 1958 for nurturing my early interest in science with an education that ultimately led me to Columbia University and the Lamont-Doherty Earth Observatory. Lamont for me was a scientific wonderland tended by scientists with global appetites for discovery and adventure. Marine geophysics, geomagnetism, and satellite altimetry of the oceans were creating a revolution of discovery, and Lamont was the center of this revolution. I owe so much to my mentor and dear friend, Walter C. Pitman III, who showed me that great science was accomplished through boundless curiosity, perseverance, and, most of all, humility.

    Edward Mellanby used the experimental method to investigate medical problems. In 1918, working at King's College for Women, London, he provided conclusive evidence that rickets is a dietary deficiency disease due to lack of a fat-soluble vitamin [D]. In Sheffield he demonstrated that cereals, in an unbalanced diet, produced rickets due to the phytic acid content reducing the availability of calcium. Mellanby became Secretary of the Medical Research Council (1933-49) but continued his research by working at weekends. In the 1930s he campaigned for the results of nutritional research to be used for the benefit of public health. During World War II he acted as a scientific adviser to the War Cabinet and had a strong influence on the food policy which maintained successfully the nutrition of the population during the shipping blockade. Mellanby was a formidable person but with sagacity he promoted new research and guided the expansion of the organization.

    This paper describes three important strands in the career of Griffith Edwards that define him as a leader and an innovator. Believing that education and science were critical for the development of addiction as a profession and as a field of inquiry, his approach was multi-faceted: educating all doctors to appreciate the fundamental issues in addiction; training psychiatrists in the complexity of 'dual diagnosis' and specific specialist intervention; and teaching that addiction could be a chronic condition which required care management over the life course. These three inter-related areas are directly related to the need for a range of practitioners to have an understanding of addiction so that patients can be properly managed. The greater our understanding of the nature of addiction behaviour, the more likely the potential to optimize treatment and train practitioners from different professional disciplines. © 2015 Society for the Study of Addiction.

  6. Edwards' approach to horizontal and vertical segregation in a mixture of hard spheres under gravity

    2003-01-01

    We study the phenomenon of size segregation, observed in models of vibrated granular mixtures such as powders or sand. This consists of the de-mixing of the different components of the system under shaking. Several mechanisms have been proposed to explain this phenomenon. However, the criteria for predicting segregation in a mixture, an issue of great practical importance, are largely unknown. In the present paper we study a binary hard-sphere mixture under gravity on a three-dimensional lattice using Monte Carlo simulations. The vertical and horizontal segregation observed during the tap dynamics is interpreted in the framework of a statistical mechanics approach to granular media in the manner of Edwards. A phase diagram for the vertical segregation is derived, and compared with the simulation data

    1992-01-01

    The purpose of this article is to introduce nurses to W. Edwards Deming and the 14 points of his management philosophy, the basis of total quality management (TQM) (Deming, 1986). Each of Deming's points has been subject to in-depth analysis from business executives for the past 40 years. Quality improvement is at the very center of TQM. To adopt TQM will require a major thought transformation for many nursing leaders, but the benefits that nurses and the profession as a whole can reap from this revolutionary style of management make the effort to change worthwhile. If you are not satisfied with the status quo and are looking for a better way to conduct business, the information in this article will begin to define quality improvement and will help you strive for the highest possible level of service to your ultimate customer--the patient.

    In her teens, Mary Edwards Walker already wore the "bloomer" outfit began to campaign for reforming the "unhygienic" clothing of women. Assertively, she attended medical school and earned her M.D. degree. Due to prejudice, her practice did not flourish and she moved to Washington to offer her medical services to the Union as the Civil War began. Rebuffed by the male medical bureaucrats, she volunteered her services anyway. Eventually, she was awarded the Congressional Medal of Honor, the only women to ever gain such distinction. After the war, Walker became a journalist, an author of two sensational books, a political lobbyist, a suffrage campaigner, a professional and public lecturer, an ardent dress reformer, a peace activist, a Utopianist and a women's right advocate. Light-years ahead of her times, Dr. Walker was an intelligent, independent, irrepressible and indefatigable proponent for a host of worthy causes.

    Rock units forming the Edwards and Trinity aquifers in northern Bexar County, Texas, are exposed within all or parts of seven 7.5-minute quadrangles: Bulverde, Camp Bullis, Castle Hills, Helotes, Jack Mountain, San Geronimo, and Van Raub. The Edwards aquifer is the most prolific ground-water source in Bexar County, whereas the Trinity aquifer supplies water for residential, commercial, and industrial uses for areas north of the San Antonio. The geologic map of northern Bexar County shows the distribution of informal hydrostratigraphic members of the Edwards Group and the underlying upper member of the Glen Rose Limestone. Exposures of the Glen Rose Limestone, which forms the Trinity aquifer alone, cover approximately 467 km2 in the county. This study also describes and names five informal hydrostratigraphic members that constitute the upper member of the Glen Rose Limestone; these include, in descending order, the Caverness, Camp Bullis, Upper evaporite, Fossiliferous, and Lower evaporite members. This study improves our understanding of the hydrogeologic connection between the two aquifers as it describes the geology that controls the infiltration of surface water and subsurface flow of ground water from the catchment area (outcropping Trinity aquifer rocks) to the Edwards water-bearing exposures.

    Roentgenograms of 28 patients with Down's syndrome were reviewed with emphasis on all previously reported abnormalities and any possible additional ones. Most of the abnormalities occurred with the same frequency as previously reported, but some less frequently reported findings were also seen. One abnormal vertebral measurement found in this series may be an additional stigma of Down's syndrome. All of the 27 cases studied cytogenetically had chromosomal abnormalities consistent with this disease. This study emphasizes the need for roentgenologic norms for the Japanese, and the desirability of combining chromosome studies with roentgenological abnormalities and clinical observations in diagnosing Down's syndrome. 19 references, 2 figures, 5 tables.

    To summarize the recent developments in endocrine disorders associated with Down syndrome. Current research regarding bone health and Down syndrome continues to show an increased prevalence of low bone mass and highlights the importance of considering short stature when interpreting dual energy x-ray absorptiometry. The underlying cause of low bone density is an area of active research and will shape treatment and preventive measures. Risk of thyroid disease is present throughout the life course in individuals with Down syndrome. New approaches and understanding of the pathophysiology and management of subclinical hypothyroidism continue to be explored. Individuals with Down syndrome are also at risk for other autoimmune conditions, with recent research revealing the role of the increased expression of the Autoimmune Regulatory gene on 21st chromosome. Lastly, Down-syndrome-specific growth charts were recently published and provide a better assessment of growth. Recent research confirms and expands on the previously known endocrinopathies in Down syndrome and provides more insight into potential underlying mechanisms.

  11. Source, variability, and transformation of nitrate in a regional karst aquifer: Edwards aquifer, central Texas.

    2016-01-01

    Many karst regions are undergoing rapid population growth and expansion of urban land accompanied by increases in wastewater generation and changing patterns of nitrate (NO3−) loading to surface and groundwater. We investigate variability and sources of NO3− in a regional karst aquifer system, the Edwards aquifer of central Texas. Samples from streams recharging the aquifer, groundwater wells, and springs were collected during 2008–12 from the Barton Springs and San Antonio segments of the Edwards aquifer and analyzed for nitrogen (N) species concentrations and NO3− stable isotopes (δ15N and δ18O). These data were augmented by historical data collected from 1937 to 2007. NO3− concentrations and discharge data indicate that short-term variability (days to months) in groundwater NO3− concentrations in the Barton Springs segment is controlled by occurrence of individual storms and multi-annual wet-dry cycles, whereas the lack of short-term variability in groundwater in the San Antonio segment indicates the dominance of transport along regional flow paths. In both segments, longer-term increases (years to decades) in NO3− concentrations cannot be attributed to hydrologic conditions; rather, isotopic ratios and land-use change indicate that septic systems and land application of treated wastewater might be the source of increased loading of NO3−. These results highlight the vulnerability of karst aquifers to NO3− contamination from urban wastewater. An analysis of N-species loading in recharge and discharge for the Barton Springs segment during 2008–10 indicates an overall mass balance in total N, but recharge contains higher concentrations of organic N and lower concentrations of NO3−than does discharge, consistent with nitrification of organic N within the aquifer and consumption of dissolved oxygen. This study demonstrates that subaqueous nitrification of organic N in the aquifer, as opposed to in soils, might be a previously

    Mitral and tricuspid valve asymmetric annular dilation represents the most important mechanism which produces insufficiency. Recent computerized in vitro and in vivo three-dimensional models have been developed in order to better understand the competing factors (annular dilation, displacement of papillary muscles, left and right ventricular geometry). The leading cause of mitral and tricuspid competence is a sphincteric action of both annuli, during systole and diastole, the loss of which produces asymmetric dilation and therefore the absence of cusp coaptation. The Cosgrove-Edwards dynamic ring corrects, alone or in combination with other procedures on the valves, this patho-anatomic feature in a physiological way by restoring the normal annular dimensions and the sphincteric movements during the cardiac cycle. Between June 1998 and May 1999, 30 adult patients underwent mitral (n = 20, Group I) or tricuspid valve repair (n = 10, Group II). Regurgitation was due to a degenerative disease in 13 Group I patients and to ischemic (n = 3), congenital (n = 2) or dilated cardiomyopathy (n = 2) in the others. In Group II the leading cause of insufficiency was functional regurgitation in 7 patients and organic in 3. Associated procedures were carried out in 4 Group I patients and in all Group II patients. Regurgitation was evaluated by transesophageal echocardiography before, during and 3 months after operation. The maximal regurgitant area (MRA) and the grade of insufficiency were evaluated using the equation: MRA 2 4 7 10 cm2 = 4+. The operative mortality was 0%. One Group I patient died 3 months after operation due to bronchopneumonia. No patient was reoperated on for plasty failure in both groups during the follow-up. Mitral insufficiency was absent (grade 0) in 17 Group I patients and mild (grade 1+) in 3 at the end of operation. At 3-month postoperative transesophageal echocardiographic control mitral insufficiency was absent in 14 patients, mild (1+) in 4 and

    The X-43A Hypersonic Experimental (Hyper-X) Vehicle hangs suspended in the cavernous Benefield Aenechoic Facility at Edwards Air Force Base during radio frequency tests in January 2000. Hyper-X, the flight vehicle for which is designated as X-43A, is an experimental flight-research program seeking to demonstrate airframe-integrated, 'air-breathing' engine technologies that promise to increase payload capacity for future vehicles, including hypersonic aircraft (faster than Mach 5) and reusable space launchers. This multiyear program is currently underway at NASA Dryden Flight Research Center, Edwards, California. The Hyper-X schedule calls for its first flight later this year (2000). Hyper-X is a joint program, with Dryden sharing responsibility with NASA's Langley Research Center, Hampton, Virginia. Dryden's primary role is to fly three unpiloted X-43A research vehicles to validate engine technologies and hypersonic design tools as well as the hypersonic test facility at Langley. Langley manages the program and leads the technology development effort. The Hyper-X Program seeks to significantly expand the speed boundaries of air-breathing propulsion by being the first aircraft to demonstrate an airframe-integrated, scramjet-powered free flight. Scramjets (supersonic-combustion ramjets) are ramjet engines in which the airflow through the whole engine remains supersonic. Scramjet technology is challenging because only limited testing can be performed in ground facilities. Long duration, full-scale testing requires flight research. Scramjet engines are air-breathing, capturing their oxygen from the atmosphere. Current spacecraft, such as the Space Shuttle, are rocket powered, so they must carry both fuel and oxygen for propulsion. Scramjet technology-based vehicles need to carry only fuel. By eliminating the need to carry oxygen, future hypersonic vehicles will be able to carry heavier payloads. Another unique aspect of the X-43A vehicle is the airframe integration

    The study of Einstein's theory of general relativity experienced a renaissance beginning in the early 1960s. Prior to this resurgence of interest, general relativity was isolated from mainstream physics-admired for its elegance, perhaps, but only from a distance. The generation of students who risked their careers by entering this neglected field has now reached the age of festschrifts. In June of 2000, Caltech hosted ;Kipfest,; a conference in honor of Kip Thorne's 60th birthday. Thorne started graduate school at Princeton in 1962 and began research in general relativity under John Wheeler's guidance in the heady early days of the renaissance. Since then, he has played a prominent role in general relativity: as co-author of the influential textbook Gravitation, as a leader in research regarding astrophysical applications of Einstein's theory, and as a co-founder and chief advocate for the Laser Interferometer Gravitational Wave Observatory (LIGO), to mention a few aspects of his far-reaching work. ;Kipfest; included 14 speakers discussing fields to which Thorne has contributed. But the conference also reflected Thorne's long-standing commitment to communicating science to a general audience: Igor Novikov, Stephen Hawking, Timothy Ferris, and Alan Lightman gave popular talks at ;Kipfest,; with Thorne himself tricked into delivering a fifth. The Future of Spacetime gathers adaptations of these five lectures, along with a lengthy introductory essay by Richard Price.

    Three new species of Pseudosmittia Edwards from the Neotropical region, P. satheri, P. larga and P. trapezoidea, are described and figured as males. Allocladiusfortispinatus (Edwards), A. globosus Andersen et al. and A. quadrus Andersen et al. are redescribed on the basis of new material and their geographical distribution updated. A phylogenetic analysis was performed in order to assess the phylogenetic relationships of the new species. As a result, the species P. sœtheri and P. larga are found to be sister species belonging to the angusta group. The species P. trapezoidea is the sister group of the clade ((P. propetropis (P. tropis--P. lamellata)) and belongs to the brevifurcata group sensu lato.

    Numerical simulations, with the Subsurface Transport Over Multiple Phases (STOMP) simulator, were applied to the field demonstration of an in-well vapor-stripping system at Edwards Air Force Base (AFB), near Mojave, California. The demonstration field site on the Edwards AFB was previously contaminated from traversing groundwater that was contained a varied composition of volatile organic compounds (VOCs), which primarily includes trichloroethylene (TCE). Contaminant TCE originated from surface basin that had been used to collect runoff during the cleaning of experimental rocket powered planes in the 1960s and 1970s. This report documents those simulations and associated numerical analyses. A companion report documents the in- well vapor-stripping demonstration from a field perspective

    2011-01-01

    In Indiana v. Edwards (2008) the U.S. Supreme Court held that a higher standard may be required for pro se competence (PSC) than for competence to stand trial (CST), but provided little guidance for the trial court judge. This survey of forensic mental health experts studied potential PSC criteria. Sixty-eight (22.7%) forensic evaluators replied. Three McGarry criteria were reported as requiring a much higher standard for PSC: to appraise the available legal defenses (45.6%), to plan a legal strategy (51.5%), and to question and challenge witnesses (44.1%). Sixty percent agreed that standby counsel should be mandatory. Respondents opined that average abilities were sufficient for intelligence (77.9%), literacy (69.1%), and verbal ability (70.6%) were sufficient. PSC examiners may wish to assess appraisal of available legal defenses, planning a legal strategy, and questioning and challenging witnesses for a higher standard than CST. Evaluators should also assess the defendant's willingness to accept standby counsel (SBC) and the defendant's motivation for attempting a pro se defense.

    The durability of the Starr-Edwards (SE) mitral caged-disk valve, model 6520, is not clearly known, and structural valve deterioration in the SE disk valve is very rare. Replacement of the SE mitral disk valve was performed in 7 patients 23-40 years after implantation. Macroscopic examination of the removed disk valves showed no structural abnormalities in 3 patients, in whom the disk valves were removed at valves excised >36 years after implantation in 4 patients. Disk fracture, a longitudinal split in the disk along its circumference at the site of incorporation of the titanium ring, was detected in the valves removed 36 and 40 years after implantation, respectively, and many cracks were also observed on the outflow aspect of the disk removed 40 years after implantation. Disk fracture and localized disk wear were found in the SE mitral disk valves implanted >36 years previously. The present results suggest that SE mitral caged-disk valves implanted >20 years previously should be carefully followed up, and that those implanted >30 years previously should be electively replaced with modern prosthetic valves

    The emergence of paediatrics as a specialty in Australian medicine dates from the last two decades of the 19th century. Among the pioneers of pre-Federation paediatrics, we include Dr Henry Edward Brown (1858-1931), an Irish-born physician and surgeon who became the first paediatrician to practise in the northern half of the Australian continent. In 1885, he was appointed as the medical superintendent of the Rockhampton Children's Hospital, itself a pioneer institution in the care of sick and injured children. Dr H.E. Brown also served as medical officer of health concurrently in three Queensland shires. He was a leader in the literary and sporting life of the busy port town of Rockhampton and a scholar and significant philanthropist in the domain of French literature. His life was and remains an exemplar of a class of pre-Federation paediatricians who established the ethos of clinical and societal service, which remains as a core feature of the speciality discipline of paediatrics in the 21st century. © 2014 The Authors.

  3. The Review as Bakhtinian Rejoinder: Edward W. Said as Music Reviewer

    Linda Hutcheon

    2015-11-01

    Full Text Available The article reads the work of the postcolonial theorist Edward Said through a Bakhtinian lens. Although Said and Bakhtin engaged differently with the politics of their time and had different ideas on the relationship between ethics and politics, their wide-ranging writings have been adapted and their ideas appropriated by scholars in many different fields-often the same ones. They shared a passion for dialogue, for exploring otherness and outsidedness, and for believing in response-ability. What the novel was to Bakhtin, pianism was to Said, the music reviewer. Said never played the role of consumer guide or gate-keeper. He was more the peer reviewer or the grade-assigning professor. The multiple possible responses of the audience always conditioned his own. Said thought like Bakhtin all his musical life, perhaps without knowing it. Said's music reviews are, by definition, responses or rejoinders. They are hybrid, double-voiced narrations and transmissions, but also appropriations, as was the novel, in Bakhtin's eyes. Said's writings on music are analyzed in light of several key Bakhtinian concepts: dialogism, addressivity, response-ability, and the role of context.

    Full Text Available Para Edward Said, o exílio e a migração são operadores de leitura caros ao pensamento crítico dissonante. Na perspectiva daquilo que chamo de uma fenomenologia saidiana do exílio, o lócus enunciativo do exilado é, para o pensador palestino, um estilo ético que implica numa posicionalidade diferencial indispensável para a compreensão crítica do mundo atual. Como veremos neste artigo, mesmo que os personagens conceituais do humanismo mundano de Said sejam, por excelência, filósofos, escritores e pensadores que experimentaram a condição de exilados, “perspectivismo do exílio” é lido, contudo, como o valor heurístico de uma posicionalidade crítica sempre fora do lugar e disponível até mesmo para aqueles que não experimentaram diretamente a migração e o desterro. Em outras palavras, este artigo procura comentar a releitura que o pensador palestino realiza, em Humanismo e crítica democrática, de Mimesis, de Erich Auerbach, propondo que o ponto de diálogo entre esses autores esteja na potência que migração e exílio desempenharam em suas trajetórias críticas.

    The Genetics Society of America's Edward Novitski Prize recognizes a single experimental accomplishment or a body of work in which an exceptional level of creativity and intellectual ingenuity has been used to design and execute scientific experiments to solve a difficult problem in genetics. The 2017 winner, Jonathan Hodgkin, used elegant genetic studies to unravel the sex determination pathway in Caenorhabditis elegans He inferred the order of genes in the pathway and their modes of regulation using epistasis analyses-a powerful tool that was quickly adopted by other researchers. He expanded the number and use of informational suppressor mutants in C. elegans that are able to act on many genes. He also introduced the use of collections of wild C. elegans to study naturally occurring genetic variation, paving the way for SNP mapping and QTL analysis, as well as studies of hybrid incompatibilities between worm species. His current work focuses on nematode-bacterial interactions and innate immunity. Copyright © 2017 by the Genetics Society of America.

    Increased agricultural land use leads to accelerated erosion and deposition of fine sediment in surface water. Monitoring of suspended sediment yields has proven challenging due to the spatial and temporal variability of sediment loading. Reliable sediment yield calculations depend on accurate monitoring of these highly episodic sediment loading events. This study aims to quantify precipitation-induced loading of suspended sediments on Prince Edward Island, Canada. Turbidity is considered to be a reasonably accurate proxy for suspended sediment data. In this study, turbidity was used to monitor suspended sediment concentration (SSC) and was measured for 2 years (December 2012-2014) in three subwatersheds with varying degrees of agricultural land use ranging from 10 to 69 %. Comparison of three turbidity meter calibration methods, two using suspended streambed sediment and one using automated sampling during rainfall events, revealed that the use of SSC samples constructed from streambed sediment was not an accurate replacement for water column sampling during rainfall events for calibration. Different particle size distributions in the three rivers produced significant impacts on the calibration methods demonstrating the need for river-specific calibration. Rainfall-induced sediment loading was significantly greater in the most agriculturally impacted site only when the load per rainfall event was corrected for runoff volume (total flow minus baseflow), flow increase intensity (the slope between the start of a runoff event and the peak of the hydrograph), and season. Monitoring turbidity, in combination with sediment modeling, may offer the best option for management purposes.

    2014-09-01

    Full Text Available Edward Burne-Jones’ cycle of The Days of Creation of 1870-66(Fogg Art Museum, Harvard University Museums, Cambridge, MA was highly praised and elegantly described by Oscar Wilde: “The picture is divided into six compartments, each representing a day in the Creation of the World, under the symbol of an angel holding a crystal globe, within which is shown the work of a day.” This essay examines how Burne-Jones visualized an unusual celestial creation where angels holding magical spheres unveil the divine manifestation for the creation of a terrestrial realm. His The Days of Creation is an aesthetic culmination of the artistic power of invention, imitation and creation of beauty. Burne-Jones borrows the divine concept of world creation to formulate his own artist creation. Selecting God’s week of creation, he empowers a daily angel to manifest the beauty and power of divine creation. Ultimately, Burne-Jones creates a cosmic utopia, a mythical heavenly and natural realm, where angels design a world of beauty to be emulated not only by the artist, but also by most of all by the viewer.

    This abstract describes work that will be done by the Applied Meteorology Unit (AMU) in assessing the success of different model configurations in predicting "wind cycling" cases at Edwards Air Force Base, CA (EAFB), in which the wind speeds and directions oscillate among towers near the EAFB runway. The Weather Research and Forecasting (WRF) model allows users to choose among two dynamical cores - the Advanced Research WRF (ARW) and the Non-hydrostatic Mesoscale Model (NMM). There are also data assimilation analysis packages available for the initialization of the WRF model - the Local Analysis and Prediction System (LAPS) and the Advanced Regional Prediction System (ARPS) Data Analysis System (ADAS). Having a series of initialization options and WRF cores, as well as many options within each core, creates challenges for local forecasters, such as determining which configuration options are best to address specific forecast concerns. The goal of this project is to assess the different configurations available and determine which configuration will best predict surface wind speed and direction at EAFB.

    2008-06-01

    Full Text Available This paper analyzes how Culture Clash problematizes Chicano masculinity through the manipulation of two iconic Chicano characters originally popularized by two films starring Edward James Olmos - the pachuco from Luis Valdez’s Zoot Suit (1981 and the portrayal of real-life math teacher Jaime Escalante in Stand and Deliver (1988. In “Stand and Deliver Pizza” (from A Bowl of Beings, 1992, Culture Clash tries to introduce new Chicano characters that can be read as masculine, and who at the same time, display alternative behaviors and characteristics, including homosexual desire. The three characters in “Stand and Deliver Pizza” represent stock icons of Chicano masculinity. In the skit, these icons are forced to interact with each other and through this process become more complex and accessible representatives of Chicano masculinity. They are able to communicate with each other to create something tangible. The pizza of course is a comedic metaphor for contemporary American society—the new melting pot.

    2016-04-01

    Full Text Available The themes of ancient and modern, of East and West, and of “journeys of discovery” form the ideological fabric of the work of Edward Bond (b. 1935, one of Britain’s most established contemporary playwrights. In his plays "Narrow Road to the Deep North" (1968 and "The Bundle" (1978, set in Japan in vaguely historicized seventeenth to nineteenth centuries, Bond uses history as a prism of looking at the present and of deconstructing the political myths of the past. He introduces the character of the great seventeenth-century Japanese poet Matsuo Basho. In both plays, Basho becomes the Brechtian narrator, the “alienating factor,” as well as the medium for Bond’s philosophical dilemma of human choice and its political implications in society. In questioning the artist’s role and the individual’s responsibility in society, Bond creates political parables that oppose the “ivory tower” intellectualism and abstract meditation to active resistance to evil. Both plays signify Bond’s own evolution from the pacifism of the Tolstoyan philosophy of “non-resistance to violence by force” ("Narrow Road to the Deep North" to the revolutionary theory of Brecht’s Epic Theatre and its social and political activism ("The Bundle".

    Full Text Available This paper explores perceptions of immigrant quality-of-life (QOL and islandness in Charlottetown, Prince Edward Island, Canada, and compares these perceptions to those of Canadian-born residents of the same provincial capital. The study employed a mixed-methods approach, including a household telephone survey conducted in the summer of 2012 (n=302, focus group interviews with immigrants in late 2012 and observations on preliminary results by the staff of the PEI Association of Newcomers to Canada (PEIANC, the primary immigrant settlement service agency on the island. The analysis of the results suggests that immigrants have a high and undifferentiated assessment of their own QOL, sense of belonging and sense of place compared to Canadian-born islanders; immigrants are also critical of the quality of education and of the range of recreational and cultural events underway on the Island. While they express positive sentiments regarding life on the Island, immigrants still feel excluded from social and economic opportunities.

  13. From Postcolonial Criticism to Critics on Postcolonial Poetics – Edward Said's Orientalism from an Iconographic Perspective

    Full Text Available Inside and outside the academy, Edward Said's work is both preeminent and controversial. Combining literary theory, the history of ideas, political analysis and the sociology of intellectuals, his groundbreaking book Orientalism has radically transformed the field of Oriental studies, arguably laying the foundation for postcolonial studies. Criticizing the condition of the Palestinian people, Said also has constantly provided a critique of US government policy in the Middle East and has thus proposed a model of intellectual skepticism which deals with political issues. This combination of political and academic interventions is one reason "for Said’s special position in contemporary Western intellectual life" (Kennedy 3. If we look at Said's classic monography as a painting of geographical knowledgelandscapes, an iconographical investigation into the traditions of knowledge and ideological styles becomes possible. This paper will begin by presenting Orientalism's arguments and will then summarize the main critiques aimed at Said. It continues to describe the analytic discourse in Orientalism based on the method of iconographic interpretation as described in Panofsky's collection of essays Meaning in the Visual Arts. This interdisciplinary approach intends to demonstrate the argumentative circularity and self-reflexivity inherent in Said's criticism: by drawing exclusively on Western histories of ideas, the concept Orientalism itself can become the object of postcolonial criticism.

    Down's syndrome (DS) is the most frequent genetic cause of intellectual disability and is a chromosomal abnormality of chromosome 21 trisomy. The pericentrin gene (PCNT) has sequenced in 21q22.3 inside of the minimal critical region for Down's syndrome. Alterations of PCNT gene are associated with dwarfism, cardiomyopathy and other pathologies. In this study, we have evaluated the possible differential expression of PCNT mRNA, by qRT-PCR, in peripheral blood leukocytes of DS subjects compared with the normal population. In the present case-control study, PCNT gene expression was increased by 72.72% in 16 out 22 DS samples compared with normal subjects. Our data suggest that changes in the expression levels of PCNT in DS subjects may be involved into the molecular mechanism of Down's syndrome.

  1. Down syndrome: coercion and eugenics.

    Science.gov (United States)

    McCabe, Linda L; McCabe, Edward R B

    2011-08-01

    Experts agree that coercion by insurance companies or governmental authorities to limit reproductive choice constitutes a eugenic practice. We discuss discrimination against families of children with Down syndrome who chose not to have prenatal testing or chose to continue a pregnancy after a prenatal diagnosis. We argue that this discrimination represents economic and social coercion to limit reproductive choice, and we present examples of governmental rhetoric and policies condoning eugenics and commercial policies meeting criteria established by experts for eugenics. Our purpose is to sensitize the clinical genetics community to these issues as we attempt to provide the most neutral nondirective prenatal genetic counseling we can, and as we provide postnatal care and counseling to children with Down syndrome and their families. We are concerned that if eugenic policies and practices targeting individuals with Down syndrome and their families are tolerated by clinical geneticists and the broader citizenry, then we increase the probability of eugenics directed toward other individuals and communities.

    The role of preconception irradiation in the etiology of Down Syndrome was examined using the techniques of record linkage. Although 909 cases of Down Syndrome, born in B.C. between 1952-70, were ascertained through a system of linked vital and health registrations, interest was restricted to the 348 case/control pairs born in the greater Vancouver area. The maternal identifying information routinely recorded on birth and ill-health registrations was used to link 155 Down Syndrome mothers and 116 control mothers to patient files at the Vancouver General Hospital. Only 28 of the case and 25 of the control mothers were subjected to diagnostic irradiation at the Vancouver Ganeral Hospital. The difference was not significant at the 5% level

    A permanent pacemaker is frequently needed after transcatheter aortic valve implantation, but the available data are mainly on the CoreValve system. To evaluate the need for new permanent pacemaker after implantation of the Edwards Sapien device, as well as related factors. We included the first 100 patients treated with the Edwards Sapien device at our institution. Of these, 12 had a permanent pacemaker before the procedure, and thus our study population was the remaining 88 patients. A permanent pacemaker was indicated in eight patients (9.1%) during hospitalization or at 30 days. After discharge, another four patients needed a pacemaker (at 42 days and three, 18, and 30 months). Two variables were associated with the need for pacemaker during hospitalization: previous dialysis (13% vs. 1%, p=0.042) and complete right bundle branch block before the procedure (25% vs. 5%, p=0.032). More than one month after the procedure, the characteristics associated with the need for pacemaker were plasma creatinine level (2.5±1.7 vs. 1.3±0.6 mg/dl, p=0.001) and previous myocardial infarction (50% vs. 10%, p=0.013). The rate of pacemaker implantation with the Edwards Sapien device was 9.1%. Right bundle branch block and dialysis were associated with this complication.

    The relative importance of magnetospheric currents and low frequency waves for pulsar braking is assessed and a model is developed which tries to account for the available pulsar timing data under the unifying aspect that all pulsars have equal masses and magnetic moments and are born as rapid rotators. Four epochs of slow-down are distinguished which are dominated by different braking mechanisms. According to the model no direct relationship exists between 'slow-down age' and true age of a pulsar and leads to a pulsar birth-rate of one event per hundred years. (Author) [pt

  6. Bone health in Down syndrome.

    Patients with Down syndrome have a number of risk factors that theoretically could predispose them to osteoporosis, such as early aging, development disorders, reduced physical activity, limited sun exposure, frequent comorbidities and use of drug therapies which could affect bone metabolism. In addition, the bone mass of these people may be affected by their anthropometric and body composition peculiarities. In general terms, studies in adults with Down syndrome reported that these people have lower areal bone mineral density (g/cm 2 ) than the general population. However, most of them have not taken the smaller bone size of people with Down syndrome into account. In fact, when body mineral density is adjusted by bone size and we obtain volumetric body mineral density (g/cm 3 ), the difference between both populations disappears. On the other hand, although people with Down syndrome have risk factor of hypovitaminosis D, the results of studies regarding 25(OH)D in this population are not clear. Likewise, the studies about biochemical bone markers or the prevalence of fractures are not conclusive. Copyright © 2017 Elsevier España, S.L.U. All rights reserved.

  7. Down syndrome and ionizing radiation.

    Verger, P

    1997-12-01

    This review examines the epidemiologic and experimental studies into the possible role ionizing radiation might play in Down Syndrome (trisomy 21). It is prompted by a report of a temporal cluster of cases of this chromosomal disorder observed in West Berlin exactly 9 mo after the radioactive cloud from Chernobyl passed. In approximately 90% of cases, Down Syndrome is due to the nondisjunction of chromosome 21, most often in the oocyte, which may be exposed to ionizing radiation during two separate periods: before the completion of the first meiosis or around the time of ovulation. Most epidemiologic studies into trisomies and exposure to ionizing radiation examine only the first period; the Chernobyl cluster is related to the second. Analysis of these epidemiologic results indicates that the possibility that ionizing radiation might be a risk factor in Down Syndrome cannot be excluded. The experimental results, although sometimes contradictory, demonstrate that irradiation may induce nondisjunction in oogenesis and spermatogenesis; they cannot, however, be easily extrapolated to humans. The weaknesses of epidemiologic studies into the risk factors for Down Syndrome at birth (especially the failure to take into account the trisomy cases leading to spontaneous abortion) are discussed. We envisage the utility and feasibility of new studies, in particular among women exposed to prolonged or repeated artificially-produced ionizing radiation.

  9. A slowing-down problem

    1958-06-15

    An infinitely long circular cylinder of radius a is surrounded by an infinite moderator. Both media are non-capturing. The cylinder emits neutrons of age zero with a constant source density of S. We assume that the ratios of the slowing-down powers and of the diffusion constants are independent of the neutron energy. The slowing-down density is calculated for two cases, a) when the slowing-down power of the cylinder medium is very small, and b) when the cylinder medium is identical with the moderator. The ratios of the slowing-down density at the age {tau} and the source density in the two cases are called {psi}{sub V}, and {psi}{sub M} respectively. {psi}{sub V} and {psi}{sub M} are functions of y=a{sup 2}/4{tau}. These two functions ({psi}{sub V} and {psi}{sub M}) are calculated and tabulated for y = 0-0.25.

  11. Diagrammatic analysis of correlations in polymer fluids: Cluster diagrams via Edwards' field theory

    International Nuclear Information System (INIS)

    Morse, David C.

    2006-01-01

    Edwards' functional integral approach to the statistical mechanics of polymer liquids is amenable to a diagrammatic analysis in which free energies and correlation functions are expanded as infinite sums of Feynman diagrams. This analysis is shown to lead naturally to a perturbative cluster expansion that is closely related to the Mayer cluster expansion developed for molecular liquids by Chandler and co-workers. Expansion of the functional integral representation of the grand-canonical partition function yields a perturbation theory in which all quantities of interest are expressed as functionals of a monomer-monomer pair potential, as functionals of intramolecular correlation functions of non-interacting molecules, and as functions of molecular activities. In different variants of the theory, the pair potential may be either a bare or a screened potential. A series of topological reductions yields a renormalized diagrammatic expansion in which collective correlation functions are instead expressed diagrammatically as functionals of the true single-molecule correlation functions in the interacting fluid, and as functions of molecular number density. Similar renormalized expansions are also obtained for a collective Ornstein-Zernicke direct correlation function, and for intramolecular correlation functions. A concise discussion is given of the corresponding Mayer cluster expansion, and of the relationship between the Mayer and perturbative cluster expansions for liquids of flexible molecules. The application of the perturbative cluster expansion to coarse-grained models of dense multi-component polymer liquids is discussed, and a justification is given for the use of a loop expansion. As an example, the formalism is used to derive a new expression for the wave-number dependent direct correlation function and recover known expressions for the intramolecular two-point correlation function to first-order in a renormalized loop expansion for coarse-grained models of

    Full Text Available The aim of this paper is, on the one hand, to make the readers acquainted with the realities of the twentieth century American family, as perceived by the two American playwrights, and, on the other hand, to underline the unusual phenomena that have been brought by the changing dynamics of the family relationships. All the five plays under discussion—All Over, A Delicate Balance, The American Dream, The Sandbox by Edward Albee, and Oh Dad, Poor Dad, Mamma's Hung You in the Closet and I'm Feelin’ So Sad by Arthur Kopit — present situations in which the female characters seem to have become the leader, taking the place of the head of the family, of the pater familias. They stop acting like loving mothers and wives, they forget to take care of their families; instead, they lock away their hearts and assume the part of some sort of tyrant: they control everyone and everything in the house, their word being the equivalent of a rule. The female characters are endowed with masculine traits, whereas the male characters are emasculated, effeminate, deprived of any kind of power. The purpose of the paper is to demystify the myth of the ideal, perfect American family,to make the readers realize that the image that has been presented to the non-American public is, in the twentieth century, nothing but a disguise. Our goal is to display the image of the new American family hoping that, in doing so, we will succeed in making the readers realize the fact that human relationships, especially the ones within the family, need to be re-established on a deeper and more meaningful level.

    Re Edwards (2011) 4 ASTLR 392; [2011] NSWSC 478 adds to the small line of cases to have considered whether a woman can not only require medical staff to remove sperm from her dead male partner, but whether she is justified in terms of law and international human rights to use it to create children. In this case a Justice of the New South Wales Supreme Court framed the issue as "what right does a woman have to take sperm from the body of her deceased partner so that she may conceive a child?" He did so, despite the manifest ambiguity and difficulty in characterising the legislative rights in this case, without referring to substantive human rights obligations under international Conventions to which Australia is a ratifying party (particularly Art 10 of the United Nations International Covenant on Economic, Social and Cultural Rights and Art 23 of the United Nations International Covenant on Civil and Political Rights. Technological advances such as those creating the possibility of capturing a dead person's sperm by electro-ejaculation and creating children by subjecting it to intracytoplasmic sperm injection in connection with in vitro fertilisation have altered the balance of individual and social interests in deciding who should be regarded as owning a dead man's sperm and how that relates to basic common law rights of bodily inviolability without free consent. It is to be regretted that in jurisdictions lacking relevant constitutional human rights, or legislation requiring coherence with international human rights, judges do not avail themselves in cases of statutory ambiguity of interpretative insights to be gained from legally binding human rights treaties to which Australia is a party.

  14. Materialism in Clifford Odets' Golden Boy and Edward Albee's The American Dream

    Full Text Available The degration in the modern pattern of heroism during the 20th century America started with the advent of science and materialistic look of life. Modern scientific studies proposed that "man is alone, absolutely alone in a universe in which his very appearance is a cosmic accident" tending, at his best, towards an animal ancestor. Man was not cared for by spiritual or moral providence. The over soul, which the American hero was supposed to melt in, was replaced by the machine which ironically metamorphosed his significance. Modern American's pursuit of worldly gains was ultimately made at the expense of his essential spiritual and moral priorities as any material gain must be balanced against a spiritual loss. This fact is made concrete in the dehumanized character of Joe, the protagonist of Clifford Odets's Golden Boy (1937, through his aggressive anti-social behaviour. He is characterized by a lack of community. Golden Boy shows how the Americans are increasingly enervated by economic strains, racist tensions and political intimidation. Almost everywhere was the lost sense of community, a sense of inner defeat and lost self-esteem. The lost sense of community was very harmful as the Americans started looking for survival at the expense of society itself; social and economic injustices arose. Odets introduces such a motif in the character of Joe. Edward Albee (1928 is one of the significant American dramatists of the 20th century, uses the dramatic forms that were prominent on the postwar European stage to articulate an unsetting vision of the United States. He wrote about the emptiness of American cultures and the uncertainties of human existence. His work castigated what he sees as a blindly materialistic society devoid of any real sense of values and national purpose. He is against the materialism in the society which goes along with consumerism. The characters in The American Dream (1961 are materialistic. Mommy represents women's addiction

  15. A Fractal Interpretation of Controlled-Source Helicopter Electromagnetic Survey Data: Seco Creek, Edwards Aquifer, TX

    2009-12-01

    The Edwards aquifer lies in the structurally complex Balcones fault zone and supplies water to the growing city of San Antonio. To ensure that future demands for water are met, the hydrological and geophysical properties of the aquifer must be well-understood. In most settings, fracture lengths and displacements occur in power-law distributions. Fracture distribution plays an important role in determining electrical and hydraulic current flowpaths. 1-D synthetic models of the controlled-source electromagnetic (CSEM) response for layered models with a fractured layer at depth described by the roughness parameter βV, such that 0≤βVlaw length-scale dependence of electrical conductivity are developed. A value of βV = 0 represents homogeneous, continuous media, while a value of 0<βV<1 shows that roughness exists. The Seco Creek frequency-domain helicopter electromagnetic survey data set is analyzed by introducing the similarly defined roughness parameter βH to detect lateral roughness along survey lines. Fourier transforming the apparent resistivity as a function of position along flight line into wavenumber domain using a 256-point sliding window gives the power spectral density (PSD) plot for each line. The value of βH is the slope of the least squares regression for the PSD in each 256-point window. Changes in βH with distance along the flight line are plotted. Large values of βH are found near well-known large fractures and maps of βH produced by interpolating values of βH along survey lines suggest previously undetected structure at depth.

    The availability of curative hepatitis C therapies has created an opportunity to improve delivery and access. Local providers, government, industry, and community groups in Prince Edward Island developed an innovative province-wide care model. Our goal was to describe the first year of program implementation. Using a community based prospective observational study design, all chronic hepatitis C referrals received from April 2015 to April 2016 were recorded in a database. Primary analysis assessed the time from referral to assessment/treatment, as well as the number of referrals, assessments, and treatment initiations. Secondary objectives included: 1) Treatment effectiveness using intention-to-treat analysis; and 2) Patient treatment experience assessed using demographics, adverse events, and medication adherence. During the study period 242 referrals were received, 123 patients were seen for intake assessments, and 93 initiated direct-acting antiviral therapy based on medical need. This is compared to 4 treatment initiations in the previous 2 years. The median time from assessment to treatment initiation was 3 weeks. Eighty-two of 84 (97.6%, 95% CI 91.7 - 99.7%) patients for whom outcome data were available achieved sustained virologic response at 12 weeks post-treatment; 1 was lost to follow-up and 1 died from an unrelated event. In the voluntary registry, 39.7% of patients reported missed treatment doses. In conclusion, results from the first 12 months of this multi-phase hepatitis C elimination strategy demonstrate improved access to treatment, and high rates of safe engagement and cure for patients living with chronic hepatitis C genotype 1 infections.

    Contamination by organochlorine pesticides (OCs), polychlorinated biphenyls, metals, and trace elements at Edwards Air Force Base (EAFB), located in the Mojave Desert, could adversely affect nesting aquatic birds, especially at the sewage lagoons that comprise Piute Ponds. Estimates of avian reproduction, in conjunction with analyses of eggs and avian foods for contaminant residues, may indicate the potential for negative effects on avian populations. From 1996 to 1999, we conducted studies at the Piute Ponds area of EAFB to evaluate the impacts of contaminants on nesting birds. Avian reproduction was evaluated in 1999. Eggs were collected for chemical analyses in 1996 and 1999, and African clawed frogs (Xenopus laevis), a likely food source, were collected for chemical analyses in 1998. Avian species occupying the higher trophic levels-black-crowned night-heron (Nycticorax nycticorax), white-faced ibis (Plegadis chihi), and American avocet (Recurvirostra americana)-generally bioaccumulated higher concentrations of contaminants in their eggs. Reproductive success and egg hatchability of night-herons and white-faced ibises in the Piute Ponds were similar to results observed at other western colonies. Deformities were observed in only one embryo in this study, but concentrations of contaminants evaluated in this ibis embryo were considered insufficient to have caused the deformities. Because clawed frogs, a primary prey item for night-herons at Piute Ponds, had no detectable levels of any OCs, it is likely that OCs found in night-heron eggs were acquired from the wintering grounds rather than from EAFB. The presence of isomers of dichlorodiphenyltrichloroethane (DDT) in ibis eggs indicated recent exposure, but invertebrates used for food by ibises were not sampled at Piute Ponds, and conclusions about the source of OCs in ibis eggs could not be made. Concentrations of contaminants in random and failed eggs of individual species were not different, and we concluded

  18. Potential impacts of wind turbines on birds at North Cape, Prince Edward Island

    As the number of new wind power generating stations in Canada grows, so do concerns regarding the environmental impact of turbines on birds, particularly on raptors and migrating songbirds. These birds are generally at greatest risk of injury or death from turbines, but the impact of these structures on all bird species must be considered on a site-by-site basis. Disturbance to breeding and wintering as a result of turbines must be better researched. This report reviews the literature on the effects of wind turbines on birds, with reference to the North Cape, Prince Edward Island. It recommends ways to reduce potential impacts of turbines on birds in that area, and suggests a program whereby the potential effects of wind turbines on birds can be monitored. The bird groups likely to be seen at North Cape include water birds, raptors, songbirds, and 5 bird species that are considered to be provincially rare. The main causes of bird mortality at wind powered energy facilities are birds flying into rotating turbine blades. Migrating birds are attracted to warning lights on the turbines and collide with the structures and they also collide with the power lines connected to the station. Poor weather conditions, such as fog, increase the occurrence of collisions with towers. Several studies have shown that most migrating and wintering bird species alter their flight paths to avoid turbines. Studies also indicate that bird mortalities at wind energy facilities are not biologically significant and that impacts are not likely to be significant if wind turbines are located in areas of poor habitat and low bird densities. 61 refs., 1 tab., 1 fig.

    Full Text Available The aim of the present in vitro study was the evaluation of the fluid dynamical performance of the Carpentier-Edwards PERIMOUNT Magna Ease depending on the prosthetic size (21, 23, and 25 mm and the cardiac output (3.6–6.4 L/min. A self-constructed flow channel in combination with particle image velocimetry (PIV enabled precise results with high reproducibility, focus on maximal and local peek velocities, strain, and velocity gradients. These flow parameters allow insights into the generation of forces that act on blood cells and the aortic wall. The results showed that the 21 and 23 mm valves have a quite similar performance. Maximal velocities were 3.03±0.1 and 2.87±0.13 m/s; maximal strain Exx, 913.81±173.25 and 896.15±88.16 1/s; maximal velocity gradient Eyx, 1203.14±221.84 1/s and 1200.81±61.83 1/s. The 25 mm size revealed significantly lower values: maximal velocity, 2.47±0.15 m/s; maximal strain Exx, 592.98±155.80 1/s; maximal velocity gradient Eyx, 823.71±38.64 1/s. In summary, the 25 mm Magna Ease was able to create a wider, more homogenous flow with lower peak velocities especially for higher flow rates. Despite the wider flow, the velocity values close to the aortic walls did not exceed the level of the smaller valves.

    Nitrate (N-NO3) concentration in groundwater, the sole source of potable water in Prince Edward Island (PEI, Canada), currently exceeds the 10 mg L-1 (N-NO3) health threshold for drinking water in 6 % of domestic wells. Increasing climatic and socio-economic pressures on PEI agriculture may further deteriorate groundwater quality. This study assesses how groundwater nitrate concentration could evolve due to the forecasted climate change and its related potential changes in agricultural practices. For this purpose, a tridimensional numerical groundwater flow and mass transport model was developed for the aquifer system of the entire Island (5660 km2). A number of different groundwater flow and mass transport simulations were made to evaluate the potential impact of the projected climate change and agricultural adaptation. According to the simulations for year 2050, N-NO3 concentration would increase due to two main causes: (1) the progressive attainment of steady-state conditions related to present-day nitrogen loadings, and (2) the increase in nitrogen loadings due to changes in agricultural practices provoked by future climatic conditions. The combined effects of equilibration with loadings, climate and agricultural adaptation would lead to a 25 to 32 % increase in N-NO3 concentration over the Island aquifer system. The change in groundwater recharge regime induced by climate change (with current agricultural practices) would only contribute 0 to 6 % of that increase for the various climate scenarios. Moreover, simulated trends in groundwater N-NO3 concentration suggest that an increased number of domestic wells (more than doubling) would exceed the nitrate drinking water criteria. This study underlines the need to develop and apply better agricultural management practices to ensure sustainability of long-term groundwater resources. The simulations also show that observable benefits from positive changes in agricultural practices would be delayed in time due to

Yet few Americans know much about this remarkable U.S.-born scholar, whose contributions equal those of the greatest scientists. He is a chemist-educator of whom we should be as proud and as well informed as we are of Linus Pauling, who was part of the westward movement of science in this country that G. N. Lewis began, or of the recently deceased Glenn Seaborg, who was one of the many students of Lewis who achieved renown. Gilbert N. Lewis was born in Weymouth, Massachusetts, in 1875, but his family moved to near Lincoln, Nebraska, in 1884. He spent two years at the University of Nebraska, but then moved to Harvard when his father became an executive at Merchants Trust Company in Boston. Young Lewis (then only 17) was also said to have been disappointed with the quality of education in Nebraska, and this may have been part of the impetus for the family's move east. After earning his baccalaureate at Harvard, he taught for a year at Phillips Andover Academy before returning to Harvard to study for his doctorate, which he completed 100 years ago, in 1899, under T.

At that time, physical chemistry was only beginning to achieve recognition as a branch of science, and its boundaries were ill defined. Edward Lewis quotes his father as often saying, "Physical chemistry is anything interesting." Like many chemists of his time, Lewis went to Europe to complete his preparation for a career; he was in the laboratories of Ostwald in Leipzig and Nernst in Göttingen in 1900-1901.

    Children with Down syndrome (DS) and acute leukemias acute have unique biological, cytogenetic, and intrinsic factors that affect their treatment and outcome. Myeloid leukemia of Down syndrome (ML-DS) is associated with high event-free survival (EFS) rates and frequently preceded by a preleukemia condition, the transient abnormal hematopoiesis (TAM) present at birth. For acute lymphoblastic leukemia (ALL), their EFS and overall survival are poorer than non-DS ALL, it is important to enroll them on therapeutic trials, including relapse trials; investigate new agents that could potentially improve their leukemia-free survival; and strive to maximize the supportive care these patients need.

    Full Text Available Within the framework of the GITARA II project an aeromagnetic survey was performed during the GANOVEXVII expedition (1992/1993 over the King Edward VII Peninsula in northwestern Marie Byrd Land (West Antarctica. This region which may represent the eastern flank of the Ross Sea rift system had previously been explored only at reconnaissance level. New total field and upward continued (10 km magnetic anomaly maps are produced and interpreted here to map and discuss the crustal structure of the Edward VII Peninsula. Tworound-shaped, high-amplitude magnetic anomalies are recognised over the Alexandra Mountains block. The anomalies are difficult to interpret since susceptibility data indicate the prevalence of non-magnetic rocks at the surface. A possible interpretation is that the anomalies are due to Cretaceous mafic intrusives distinct from weakly magnetic Byrd Coast Granite of the adjacent Rockefeller Mountains block. Alternatively the anomalies could be related to buried pluton-sized Devonian Ford Granodiorite intruded by dikes. If Cretaceous in age, the former intrusives revealed from the magnetics could also be responsible for contact metamorphism of the adjacent Alexandra Mountains migmatites. Lower amplitude circular anomalies over the Central Plateau and Prestrud Inlet are likely to be caused by unexposed Devonian Ford Granodiorite which crops out in the Ford Ranges. Elongated high-frequency anomalies of the Sulzberger Bay are similar to those recognised over seismically constrained Cenozoic rift-related volcanics of the Ross Sea. A broad magnetic low over the Sulzberger Ice Shelf may be indicative of a fault bounded graben-like basin with sedimentary infill. Overall recognition of magnetic anomaly patterns and trends reveals segmentation of the Edward VII Peninsula and of the adjacent marine areas in distinct crustal blocks. Faults may separate these blocks and they are interpreted to reflect multiple Cretaceous and maybe Cenozoic crustal

    Prosthesis-patient mismatch (PPM) is associated with increased mid-term and long-term mortality rates after aortic valve replacement (AVR). This study aimed to evaluate the efficacy of the Carpentier-Edwards Perimount Magna and Magna Ease (CEPMs) aortic bioprostheses to reduce the incidence of PPM.Methods and Results:Altogether, 282 consecutive patients (113 women, mean age 69.9±9.9 years) underwent AVR with a CEPMs between 2008 and 2015. They were divided into 3 groups based on the risk of PPM as a result of their body surface area and aortic annular diameter (BSA/AnnD ratio): low-risk (LR) group: 0.64±0.05 m 2 /cm (n=94); medium-risk (MR) group: 0.73±0.02 m 2 /cm (n=94); high-risk (HR) group: 0.83±0.05 m 2 /cm (n=94). The 30-day mortality rate was 0.4%. The 5-year actuarial survival rates were 93.2%, 92.3%, and 94.8% for groups LR, MR, and HR, respectively. No explants as a result of structural valve deterioration occurred. No patients showed severe PPM, defined as a measured effective orifice area index (EOAI) <0.65 cm 2 /m 2 . Although there were significant (P<0.05) differences in EOAI (0.98±0.2, 0.90±0.21, and 0.88±0.1 cm 2 /m 2 among the LR, MR, and HR groups, respectively), the corresponding transvalvular mean pressure gradients (13.0±5.5, 12.3±4.0, 12.7±5.3 mmHg) and regression rates of the left ventricular mass (29.8%, 28.7%, 28.9%) were similar among groups. CEPMs provide low surgical risk and reduce the risks of PPM, even in HR patients, with excellent hemodynamics.

Aim of this study was to analyze the incidence of PPM after transcatheter aortic valve implantation (T-AVI) using the Edwards SAPIEN prosthesis and its relation to postoperative outcome. 200 consecutive high-risk patients underwent transapical aortic valve implantation (TA-AVI) between February 2006 and January 2009 and fulfilled 1 year follow-up were included. Severe PPM was defined as indexed EOA (EOAi) <0.65 cm2/m2 and moderate PPM as EOAi = 0.65-0.85 cm2/m2, EOA was calculated from transthoracic echocardiographic (TTE) measurements using the continuity equation. Total 112 patients with sufficient postoperative TTE image quality formed the study group. EOAi increased from 0.3 ± 0.1 cm2/m2 (preoperatively) to 1.1 ± 0.4 cm2/m2 after TA-AVI (p < 0.001). According to the standard definitions, PPM was seen in 38.4% of the patients and 9.8% presented with severe PPM. The occurrence of PPM had neither an effect on clinical outcome in terms of NYHA class nor on survival. Patients with PPM had significantly higher postoperative transprosthetic gradients (mean gradient 10.4 ± 4.1 versus 7.1 ± 3.0 mm Hg, p < 0.001). Based on the in vitro EOA data obtained from pulse duplicator measurements, however, none of the patients was judged to have PPM. Transcatheter AVI provides good antegrade hemodynamic function and EOAi improves significantly. According to standardized evaluations PPM occurs after TA-AVI, but it is not associated with adverse outcomes. Thus use of the continuity equation may not adequately reflect the situation after T-AVI or the current definition of PPM is not suitable for T-AVI prostheses.

    The expandable sheath was designed with a lower profile in order to reduce the incidence of vascular complications of transcatheter aortic valve implantation using transfemoral approach. However, once the prosthesis has crossed the sheath, it could be difficult to retrieve it from the body. This is the first case of successful bail-out in an instance of delivery balloon shaft malfunction subsequent to the crossing of an expandable sheath during implantation of an Edwards SAPIEN 3 prosthesis. © 2016 Wiley Periodicals, Inc. © 2016 Wiley Periodicals, Inc.

    Dr Percy Charles Edward d'Erf Wheeler, a medical missionary of the London Society for Promoting Christianity Amongst the Jews, spent 24 years (1885-1909) as head of the English medical institution in Jerusalem. Wheeler dedicated the years he served in Palestine to promote the medical condition of the Jews as a means of missionary work. The most significant of his achievements was his leading role in the founding of the new British Hospital for the Jews in Jerusalem, the flagship of the British presence in Palestine, to be inaugurated in 1897.

    Water-chemistry data from the Edwards aquifer for 1976-85, consisting of nearly 1,500 chemical analyses from 280 wells and 3 springs, were used to statistically evaluate relations among ground-water chemistry, hydrogeology, and land use. Five land uses associated with sampled wells were classified on the basis of published information and field surveys. Four major subareas of the aquifer were defined to reflect the relative susceptibility of ground water to contamination originating from human activities using hydrogeologic and tritium data.

  10. Describing the self through the photographic medium: the autobiographic fictions of John M. Coetzee, Roland Barthes and Edward Said

    Full Text Available The present study investigates the different approaches to autobiography of three writers – John M. Coetzee, Edward Said and Roland Barthes – who are divided by background and historical circumstances but share the terrain of postcolonial and postmodern theory. In particular, the focus is on the use they make of photographs – real or evoked – that accompany their personal accounts. Using photography as a counterpoint and a parallel to autobiography, they all try and come to terms with issues of subjectivity, representation and authenticity. As a result, their life-long convictions will be challenged by the power of memory, leaving way to a renewed sense of self.

    Groundwater management in the Edwards Aquifer in Texas is in the process of moving away from a traditional right of capture economic regime toward a more environmentally sensitive scheme designed to preserve endangered species habitats. This study explores economic and environmental implications of proposed groundwater management and water development strategies under a proposed regional Habitat Conservation Plan. Results show that enhancing the habitat by augmenting water flow costs $109-1427 per acre-foot and that regional water development would be accelerated by the more extreme possibilities under the Habitat Conservation Plan. The findings also indicate that a water market would improve regional welfare and lower water development but worsen environmental attributes.

    The objective of the study was to elucidate if individuals with Down`s syndrome (DS) are likely to experience an increased risk of osteoporosis with advancing age, in addition to precocious aging and their skeletal anomalies. Bone mineral density (BMD) was measured in 22 home-reared adults (9 males and 13 females; age 26.22 {+-} 4.45 and 23.65 {+-} 3.23 years, respectively) by dual energy X-ray absorptiometry (DXA). The BMD of the second to fourth lumbar vertebrae was measured in posteroanterior projection and the mean density expressed as grams per square centimetre. The BMD of DS individuals was compared with 27 control subjects (12 males and 15 females) of the same age (age 24.16 {+-} 3.46 and 23.86 {+-} 2.92 years, respectively). The results showed that the BMD of the lumbar spine in the males as well as in the females with DS was significantly lower than that in their control counterparts (p < 0.001). Comparing the DS males with the females, the BMD was lower in the males at a level of 9 %. Factors that contribute to this disorder may be mainly the muscular hypotonia, the sedentary lifestyle and the accompanying diseases which frequently observed in the syndrome. Future studies must be focused on the biochemistry of bone metabolism, the evaluation of gonadal, thyroid and parathyroid function, and the genes of the extra chromosome 21. (orig.)

    The Edwards Duromedics valve (Baxter Healthcare Corp., Edwards Division, Santa Ana, Calif.) was designed with a self-irrigating hinge mechanism to reduce thromboembolic complications. After good initial clinical results, distribution was suspended in 1988 after reports of valve fracture after 20,000 valves had been implanted. The manufacturer conducted extensive studies to improve the Edwards Duromedics and reintroduced a modified version, which is available as Edwards Tekna. The purpose of the study was the evaluation of long-term results of the original Edwards Duromedics that might be important for the current version, the Edwards Tekna valve. A prospective clinical 10-year follow-up was performed of 508 patients who underwent valve replacement with the Edwards Duromedics valve in the aortic (n = 268), mitral (n = 183), and aortic and mitral (n = 56) position. The perioperative mortality rate was 6.9%; follow-up was 98% complete, comprising 3648 patient-years for a mean follow-up of 86 months (range: 33 to 144 months). The actuarial freedom from complications at the 10-year follow-up and the incidence rate (percent per patient-year) were as follows: late mortality rate, 69.2% +/- 2.4% (3.5% per patient-year); thromboembolism, 90.7% +/- 1.6% (0.96% per patient-year); anticoagulation-related hemorrhage, 87.7% +/- 1.7% (1.34% per patient-year); prosthetic valve endocarditis, 96.7% +/- 0.09% (0.38% per patient-year); valve-related mortality rate, 89.3% +/- 1.6% (1.21% per patient-year); valve failure, 86.2% +/- 1.85% (1.54% per patient-year); and valve-related morbidity and mortality rate, 71.1% +/- 2.3% (3.2% per patient-year). Three leaflet escapes were observed (one lethal, two successful reoperations; 99.1% +/- 0.05% freedom, 0.08% per patient-year). All patients functionally improved (86% in New York Heart Association classes I and II), and incidence of anemia was insignificant. These results confirm that the Edwards Duromedics valve shows excellent performance

    The Edwards and Trinity aquifers are major sources of water in south-central Texas and are both classified as major aquifers by the State of Texas. The population in Hays and Comal Counties is rapidly growing, increasing demands on the area’s water resources. To help effectively manage the water resources in the area, refined maps and descriptions of the geologic structures and hydrostratigraphic units of the aquifers are needed. This report presents the detailed 1:24,000-scale bedrock hydrostratigraphic map as well as names and descriptions of the geologic and hydrostratigraphic units of the Driftwood and Wimberley 7.5-minute quadrangles in Hays and Comal Counties, Tex.Hydrostratigraphically, the rocks exposed in the study area represent a section of the upper confining unit to the Edwards aquifer, the Edwards aquifer, the upper zone of the Trinity aquifer, and the middle zone of the Trinity aquifer. In the study area, the Edwards aquifer is composed of the Georgetown Formation and the rocks forming the Edwards Group. The Trinity aquifer is composed of the rocks forming the Trinity Group. The Edwards and Trinity aquifers are karstic with high secondary porosity along bedding and fractures. The Del Rio Clay is a confining unit above the Edwards aquifer and does not supply appreciable amounts of water to wells in the study area.The hydrologic connection between the Edwards and Trinity aquifers and the various hydrostratigraphic units is complex because the aquifer system is a combination of the original Cretaceous depositional environment, bioturbation, primary and secondary porosity, diagenesis, and fracturing of the area from Miocene faulting. All of these factors have resulted in development of modified porosity, permeability, and transmissivity within and between the aquifers. Faulting produced highly fractured areas which allowed for rapid infiltration of water and subsequently formed solutionally enhanced fractures, bedding planes, channels, and caves that

    The Haliplidae, Gyrinidae and Dytiscidae (Coleoptera) of Prince Edward Island, Canada were surveyed during the years 2004-2005. A total of 2450 individuals from 79 species were collected from 98 different localities, among which 30 species are newly recorded from that region. Among these, Acilius sylvanus Hilsenhoff, Rhantus consimilis Motschulsky and Neoporus sulcipennis (Fall) stand out as representing the easternmost reports of these species in Canada. Once removed, Gyrinus aquiris LeConte (Gyrinidae) is reinstated in the faunal list of Prince Edward Island. According to this study and literature 84 species of Hydradephaga are currently known from Prince Edward Island. The Nearctic component of the fauna is made up of 68 species (80.9%) and the Holarctic component of 16 species (19.1%). Most species are characteristic of the Boreal and Atlantic Maritime Ecozones and have a transcontinental distribution. In an examination of the Hydradephaga of insular portions of Atlantic Canada, we found that despite significantly different land areas and different distances to the neighbouring continental mainland the island faunas of Prince Edward Island and insular Newfoundland are very similar in the number of species (84 and 94 species respectively) despite differences in composition. With a land area significantly larger than that of Prince Edward Island, however, the fauna of Cape Breton Island was 39% smaller consisting of 53 species. This difference could be due to the comparative lack of collecting efforts on Cape Breton Island.

    A cellular pyramid is an exponentially tapering stack of arrays of processors (cells), where each cell is connected to its neighbors (siblings) on its own level, to a parent on the level above, and to its children on the level below. It is shown that in some situations, if information flows top-down only, from fathers to sons, then a cellular pyramid may be no faster than a one-level cellular array; but it may be possible to use simpler cells in the pyramid case. 23 references.

    Poulain, Cedric; Dangla, Remie; Guinard, Marion

    2009-11-01

    We present experimental evidence that a bubble moving in a fluid in which a well-chosen acoustic noise is superimposed can be significantly slowed down even for moderate acoustic pressure. Through mean velocity measurements, we show that a condition for this effect to occur is for the acoustic noise spectrum to match or overlap the bubble's fundamental resonant mode. We render the bubble's oscillations and translational movements using high speed video. We show that radial oscillations (Rayleigh-Plesset type) have no effect on the mean velocity, while above a critical pressure, a parametric type instability (Faraday waves) is triggered and gives rise to nonlinear surface oscillations. We evidence that these surface waves are subharmonic and responsible for the bubble's drag increase. When the acoustic intensity is increased, Faraday modes interact and the strongly nonlinear oscillations behave randomly, leading to a random behavior of the bubble's trajectory and consequently to a higher slow down. Our observations may suggest new strategies for bubbly flow control, or two-phase microfluidic devices. It might also be applicable to other elastic objects, such as globules, cells or vesicles, for medical applications such as elasticity-based sorting.

Para isso, foi necessário expor o que Amy Allen compreende pelo termo teoria crítica, resgatando a sua denúncia contra a “mainstream” da teoria crítica contemporânea (especialmente, Habermas e Honneth, que na sua acurada interpretação teria recaído em um déficit pós-colonial inaceitável, em virtude da excessiva influência de Hegel e dos jovens hegelianos, sobretudo na reconciliação apressada que tal mainstream faz entre a noção de progresso histórico e de história empírica.

    2007-12-01

    A brief account is given of the evolution of the concept of working memory from a unitary store into a multicomponent system. Four components are distinguished, the phonological loop which is responsible for maintaining speech-based information, the visuospatial sketchpad performing a similar function for visual information, the central executive which acts as an attentional control system, and finally a new component, the episodic buffer. The buffer comprises a temporary multidimensional store which is assumed to form an interface between the various subsystems of working memory, long-term memory, and perception. The operation of the model is then illustrated through an account of a research programme concerned with the analysis of working memory in Down syndrome.

    Full Text Available OBJECTIVES: Oral health in Down syndrome children has some peculiar aspects that must be considered in the follow-up of these patients. This study focuses on characterizing the environmental and host factors associated with dental caries in Portuguese children with and without Down syndrome. METHODS: A sibling-matched, population-based, cross-sectional survey was performed. RESULTS: Down syndrome children presented a significantly greater percentage of children without caries, 78% vs. 58% of non-Down syndrome siblings. This difference in the DMFT index (number of decayed, missing and filled teeth essentially reflects data obtained from treated teeth, for which 91% of children with Down syndrome had never had a tooth treated vs. 67% of siblings. This result was statistically significant, whereas results for decayed and lost teeth did not differ between Down syndrome children and their unaffected siblings. Additionally, in Down syndrome children, a delayed eruption of the second molar occurs. Down syndrome children and their siblings have similar oral hygiene habits, but a higher percentage of Down syndrome children visit a dentist before the age of three years, in comparison to their siblings. Bruxism was also more common in Down syndrome children compared to their siblings. CONCLUSIONS: Our results show that Portuguese children with Down syndrome have lower caries rates than children without Down syndrome. This reduced prevalence may be associated with the parents' greater concern about oral health care in Down syndrome children, resulting in their taking them sooner to visit a dentist, as well as to a higher bruxism prevalence and delayed tooth eruption.

    The thyroid status of 106 adults with Down's syndrome was assessed. Six were previously diagnosed as hypothyroid and were already receiving thyroxine. A further 37 patients showed abnormal thyroid function. Biochemical evidence of hypothyroidism (T4 less than 50 nmol/l and T.S.H. greater than 4 mu/less than) was found in one person. Six patients were found to have an unequivocally elevated T.S.H. but normal T4 (T4 greater than 50 nmol/l and T.S.H. greater than 20 mu/l) and 29 were found to have a modest elevation of T.S.H. but normal T4 concentration (T4 greater than 50 nmol/l and T.S.H. between 4 and 20 mu/l). There was one patient with mild thyrotoxicosis (T4 = 180 nmol/l and T.S.H. less than 0.1 mu/l). Clinical findings were of little use in making a diagnosis of hypothyroidism in this group of patients. A raised level of thyroid microsomal auto-antibodies was found in about a third of the patients, this occurred more commonly in females and slightly more often in those with a raised thyroid stimulating hormone. The importance of this is discussed. Recommendations for regular biochemical screening are made.

    National medical organizations recommend that during prenatal counseling sessions, healthcare providers discuss how having a child with Down syndrome (DS) might impact the family unit. Few studies, to date, have surveyed families about their life experiences. For this investigation, we examined 41 family attitudes, which were obtained from mailed questionnaires completed by 1,961 parents/guardians, 761 brothers/sisters, and 283 people with DS who were members of six DS non-profit organizations, chosen for their size, ethnic/racial diversities, and geographic distribution throughout the United States. About 83% of families reported to all being proud of the family member with DS, and 87% reported to all feeling love for the member with DS. Younger siblings (ages 9-11) were more likely to feel embarrassed by their sibling with DS if their parents/guardians also did. If one or more parents/guardians felt that their children without DS did have a good relationship with their child with DS, siblings were more likely to report that they loved and liked their brother/sister with DS. Overall, our data demonstrate that positive themes tend to dominate within modern-day families who have members with DS, although challenges were not insignificant for some. © 2015 Wiley Periodicals, Inc.

    The present invention concerns an externally disposed reactor shut-down device for an FBR type reactor using liquid sodium as coolants. An introducing pipe having an outlet port disposed at an upper portion thereof is disposed at a lower end of an upper guide tube. An extension tube, an L-shaped measuring wire support and a measuring wire are disposed at the inside of the guide tube. With such a constitution, low temperature coolants flown out from the lower guide tube of a control rod and a great amount of high temperature coolants flown out from the lower guide tube of a fuel assembly are introduced smoothly to the introducing tube having the measuring wire support disposed therein. Accordingly, the high temperature coolants can be prevented from flowing out to the outside of the introducing tube and coolants after mixing can be flown and hit against a curie point electromagnet efficiently. This can make the response to abnormal temperature rise of coolants satisfactory and can provide reliable reactor scram. (I.N.)

We provide new data that extends the geographical distributions of E. bituberculatus to the coast of the states of Paraná and Santa Catarina (Brazil, and offer new records from Belize and Costa Rica. Epialtus brasiliensis is recorded for the first time in the state of Rio Grande do Sul (Brazil, and A. dissimulatus is reported from Quintana Roo, Mexico. The distribution of A. dissimulatus, previously known as endemic to Brazil, has a gap between the states of Espírito Santo and Rio de Janeiro. However, this restricted southern distribution is herein amplified by the Mexican specimens.

    A reproductive biology study of the spider crab Schizophrys aspera (H. Milne Edwards, 1834) was conducted in the Suez Canal from July 2012 to June 2013. The annual sex ratio (Male:Female) of S. aspera was female biased with values of 1:1.25. Out of the four ovarian development stages of this crab, two stages were observed in the Suez Canal throughout the whole year. The ovigerous crab's carapace width varied from 28 to 52 mm. This crab species can spawn during most of the year in the canal water, with a peak during late spring and early winter. The fecundity of ovigerous females ranged between 2349 and 13600 eggs with a mean of 5494 ± 1486 eggs. Female crabs that reached sexual maturity exhibited a minimum carapace width varying between 22 and 46 mm, and fifty percentage of all ovigerous females showed a carapace width of 36 mm.

  15. Simulation of flow in the Edwards Aquifer, San Antonio region, Texas, and refinement of storage and flow concepts

    The Edwards aquifer is a complexly faulted, carbonate aquifer lying within the Balcones fault zone of south-central Texas. The aquifer consists of thin- to massive-bedded limestone and dolomite, most of which is in the form of mudstones and wackestones. Well-developed secondary porosity has formed in association with former erosional surfaces within the carbonate rocks, within dolomitized-burrowed tidal and evaporitic deposits, and along inclined fractures to produce an aquifer with transmissivities greater than 100 ft2/s. The aquifer is recharged mainly by streamflow losses in the outcrop area of the Edwards aquifer and is discharged by major springs located at considerable distances, as much as 150 mi, from the areas of recharge and by wells. Ground-water flow within the Edwards aquifer of the San Antonio region was simulated to investigate concepts relating to the storage and flow characteristics. The concepts of major interest were the effects of barrier faults on flow direction, water levels, springflow, and storage within the aquifer. A general-purpose, finite-difference model, modified to provide the capability of representing barrier faults, was used to simulate ground-water flow and storage in the aquifer. The approach in model development was to conduct a series of simulations beginning with a simple representation of the aquifer framework and then proceeding to subsequent representations of increasing complexity. The simulations investigated the effects of complex geologic structures and of significant changes in transmissivity, anisotropy, and storage coefficient. Initial values of transmissivity, anisotropy, and storage coefficient were estimated based on concepts developed in previous studies. Results of the simulations confirmed the original estimates of transmissivity values (greater than 100 square feet/s) in the confined zone of the aquifer between San Antonio and Comal Springs. A storage coefficient of 0.05 in the unconfined zone of the aquifer

  19. Incidence and Carrier Frequency of CFTR Gene Mutations in Pregnancies With Echogenic Bowel in Nova Scotia and Prince Edward Island.

    Science.gov (United States)

    Miller, Michelle E; Allen, Victoria M; Brock, Jo-Ann K

    2018-03-01

    Fetal echogenic bowel (echogenic bowel) is associated with cystic fibrosis (CF), with a reported incidence ranging from 1% to 13%. Prenatal testing for CF in the setting of echogenic bowel can be done by screening parental or fetal samples for pathogenic CFTR variants. If only one pathogenic variant is identified, sequencing of the CFTR gene can be undertaken, to identify a second pathogenic variant not covered in the standard screening panel. Full gene sequencing, however, also introduces the potential to identify variants of uncertain significance (VUSs) that can create counselling challenges and cause parental anxiety. To provide accurate counselling for families in the study population, the incidence of CF associated with echogenic bowel and the carrier frequency of CFTR variants were investigated. All pregnancies for which CF testing was undertaken for the indication of echogenic bowel (from Nova Scotia and Prince Edward Island) were identified (January 2007-July 2017). The CFTR screening and sequencing results were reviewed, and fetal outcomes related to CF were assessed. A total of 463 pregnancies with echogenic bowel were tested. Four were confirmed to be affected with CF, giving an incidence of 0.9% in this cohort. The carrier frequency of CF among all parents in the cohort was 5.0% (1 in 20); however, when excluding parents of affected fetuses, the carrier frequency for the population was estimated at 4.1% (1 in 25). CFTR gene sequencing identified an additional VUS in two samples. The incidence of CF in pregnancies with echogenic bowel in Nova Scotia and Prince Edward Island is 0.9%, with an estimated population carrier frequency of 4.1%. These results provide the basis for improved counselling to assess the risk of CF in the pregnancy, after parental carrier screening, using Bayesian probability. Counselling regarding VUSs should be undertaken before gene sequencing. Copyright © 2017 Society of Obstetricians and Gynaecologists of Canada. Published by

  20. Direct evidence of hydration into mantle during shearing below a trasform fault: Prince Edward transform fault, Southwest Indian Ridge

    Science.gov (United States)

    2017-12-01

    Southwest Indian Ridge (SWIR) is located to the southwest of Rodriguez Triple Junction, where three Indian ocean ridges meet (Zhou & Dick, 2013, Nature). SWIR is one of the slowest spreading ocean ridges in the world. In this study, we studied microstructural development of 21 peridotite samples obtained from Prince Edward transform fault of SWIR by PROTEA5 cruise in 1983. The peridotites consist dominantly of olivine, orthopyroxene and clinopyroxene with minor amounts of amphibole and plagioclase as well as secondary minerals such as serpentine and magnetite. The peridotites were classified into four groups based on their microstructures: 3 ultramylonites mostly consisting of extremely fine crystals (3-5µm), 13 heterogeneous tectonites consisting of coarse-grained crystals and fine-grained matrix, 1 cataclasite and 4 intensely serpentinized peridotites. Olivine Mg# is 0.90-0.91 and spinel Cr# is 0.1-0.35. Amphibole crystals have chemical compositions of tremolite and magnesio-hornblende and they were intensely deformed within the ultramylonites and the heterogeneous tectonites, indicating that they have occurred before or during intense shearing in mantle. Moreover, extremely fine grain sizes of olivine and microboudin textures in both pyroxene and spinel crystals suggest that these peridotites have been sheared under high stress conditions. Furthermore, olivine crystal-fabrics within the amphibole bearing peridotites have B and E types that could be developed under hydrous conditions, whereas olivine fabrics within the other peridotites have A and D types that could be developed under anhydrous conditions (Karato et al., 2008, Annu. Rev. Earth Planet. Sci.). Consequently, the petrophysical characteristics of peridotites in this study indicate that the uppermost mantle below the Prince Edward transform fault has been locally but intensely hydrated during shearing due to transform movement.

  1. Assessing the vulnerability of public-supply wells to contamination—Edwards aquifer near San Antonio, Texas

    This fact sheet highlights findings from the vulnerability study of a public-supply well field in San Antonio, Texas. The well field consists of six production wells that tap the Edwards aquifer. Typically, one or two wells are pumped at a time, yielding an average total of 20-21 million gallons per day. Water samples were collected from public-supply wells in the well field and from monitoring wells installed along general directions of flow to the well field. Samples from the well field contained some constituents of concern for drinking-water quality, including nitrate; the pesticide compounds atrazine, deethylatrazine, and simazine; and the volatile organic compounds tetrachloroethene (also called perchloroethene, or PCE), chloroform, bromoform, and dibromochloromethane. These constituents were detected in untreated water at concentrations much less than established drinking-water standards, where such standards exist. Overall, the study findings point to four primary factors that affect the movement and fate of contaminants and the vulnerability of the public-supply well field in San Antonio, Texas: (1) groundwater age (how long ago water entered, or recharged, the aquifer), (2) fast pathways for flow of groundwater through features formed or enlarged by dissolution of bedrock, (3) recharge characteristics of the aquifer, and (4) natural geochemical processes within the aquifer. A computer-model simulation of groundwater flow and transport was used to estimate the traveltime (or age) of water particles entering public-supply well W4 in the well field. Modeled findings show that almost half of the water reaching the public-supply well is less than 2 years old. Such a large percentage of very young water indicates that (1) contaminants entering the aquifer may be transported rapidly to the well, (2) there is limited time for chemical reactions to occur in the aquifer that may attenuate contaminants, and (3) should recharge water become contaminated with

    The Down Force Calibration Stand was developed to provide an improved means of calibrating equipment used to apply, display and record Core Sample Truck (CST) down force. Originally, four springs were used in parallel to provide a system of resistance that allowed increasing force over increasing displacement. This spring system, though originally deemed adequate, was eventually found to be unstable laterally. For this reason, it was determined that a new method for resisting down force was needed

    Eight years ago when the Rettenmeier family from Germany bought Liptovska drevarska fabrika they bought a small sawmill in Liptovsky Hradok that used outdated technologies and processed only a few thousand cubic meters of wood a year. Gradually they invested over 1 bil. Sk (29.4 mil. EUR) in renovation and expansion and soon their company, Rettenmeier Tatra Timber, became the only high capacity sawmill in the country. Last year, it processed around half a million cubic meters of wood which represents around 10% of Slovakia's annual timber production. Rettenmeier, with annual revenues of around 2 bil. Sk (58.82 mil. EUR), became one of the key wood processing companies in Slovakia. But the week before last the company was hit by an accident which not even the best economic performance or market position could have prevented. The sawmill burnt down. The fire broke out only two days after the explosion at the military facility in Novaky. No-one was seriously hurt but the firemen had no chance to fight the fire at the sawmill. Most of the halls and machinery were completely destroyed. The cause of the fire is still under investigation and the total damage has not yet been assessed. But the damage will reach hundreds of millions. And the damage to the owners is even bigger as the fire destroyed the main production part of the company - the sawmill and so all the other timber processing facilities had to be closed. Luckily, the company was insured not only against direct damage, but also against loss of profit related to the halting of production. (authors)

At each date, seeds were tested for final germination percentage and for seedling vigour traits. Timothy seeds had a maximum germination (88% and the best seedlings vigour at 90 DAH, which implies that early autumn (September-October is the best sowing period for freshly harvested seeds of timothy. Timothy seed germination was poor from 270 DAH (73%. The best germination and vigour of Italian ryegrass and cocksfoot seedlings were between 270 and 330 DAH, which equates to spring sowing time (March-April in the succeeding year. Cocksfoot and Italian ryegrass seeds maintained satisfactory germination levels up to 630 DAH (81% and 810 DAH (81%, respectively. The data can serve for the determination of a proper storage duration management between harvest and sowing of the tested species under ambient conditions of south-eastern Europe.Durante o armazenamento, diferentes espécies comportam-se diferentemente quanto à dormência e crescimento de plântulas.

    2008-02-01

    Phosphor down-conversion of blue organic light-emitting diodes (OLEDs) is one approach to generate white light, which offers the possibility of easy color tuning, a simple device architecture and color stability over lifetime. In this article previous work on down-conversion devices in the field of organic solid state lighting is briefly reviewed. Further, bottom emitting down-conversion OLEDs are studied from an optical point of view. Therefore the physical processes occurring in the down-conversion layer are translated into a model which is implemented in a ray tracing simulation. By comparing its predictions to experimental results the model is confirmed. For the experiments a blue-emitting polymer OLED (PLED) panel optically coupled to a series of down-conversion layers is used. Based on results obtained from ray tracing simulation some of the implications of the model for the performance of down-conversion OLEDs are discussed. In particular it is analysed how the effective reflectance of the underlying blue OLED and the particle size distribution of the phosphor powder embedded in the matrix of the down-conversion layer influence extraction efficiency.

  13. Edward Said’s Worldliness, Amateurism and Heterotopia: Negotiating the Interdisciplinarity of Literary Theory, Canonicity, and Paradigm

    Directory of Open Access Journals (Sweden)

    Ayman Abu-Shomar

    2016-06-01

    Full Text Available Literary criticism nowadays is essentially crossing the boundaries of disciplinarity and canonicity where literary theory has increasingly been shaped by overlapping concepts and branching out of theories as well as whipping out the limitations imposed by theory itself. The post-conditions of contemporaneity have imposed a view of reading and analysing the literary text that is dynamic, proliferated and in flux as well as resistant to monolithic critique and confined disciplines and professionalization. This outlook has increasingly made the notions of literary criticism, theoretical paradigms and canons not only artificial and irrelevant to our materialistic world, but, in many cases, ‘violent’ to those whose life concerns exist in the margins of these paradigmatic notions. In this essay, I argue that those of us who aspire to an interdisciplinary and a metacritical analyses would be well served by importing inspirations from Edward Said’s work, scholarship and life, particularly drawing on his ‘Worldliness’, ‘Amateurism’ and ‘Heteroglossia’ (or heterotopia as well as drawing examples from his negotiation with intellectual paradoxes and tensions informed by his positionality as a border crosser intellectual (or his exilic consciousness. Specifically, this article engages with Said as an author of a radically secular body of work marked by as comportment towards being, and as an example of an “amateur” critic who “speak[s] truth to power”. It argues that Said instates a critically-interrogative scholarship as antidote to essentialist, politicised, determinist and hegemonic literary canons (whether those of texts or theory which are paradigmatically informed by relations of power in academia. The paper argues that through the investment of his scholarship and personal life, Said rejects academic institutions and affiliations with their tendency towards doctrinaire assumptions of critical work. Further to this, Said

    Full Text Available Background: Down syndrome is an easily recognized congenital disease anomaly, a common autosomal chromosomal anomaly with high prevalence of malocclusion. Orthodontic treatment demand should be high but it seems difficult to be done because of specific condition of disability. Purpose: The purpose of this literature review was to discribe the orthodontic problems found in Down syndrome patients and several consideration that shoud be done to treat them. Reviews: Many studies report the high prevalence of malocclusion among people with Down syndrome. There is a greater frequency of clas III relationship, crossbite, crowding and also open bite. Several problems might appear in the treatment because of dental, medical, mental, and behavioural factor. Conclusion: It is concluded that orthodonic treatment can be performed in Down syndrome patient, although several difficulties may appear. Good consideration in mental, behavior, medical and also dental condition will influence whether the treatment will success or not. Special care and facilities will support the orthodontic treatment.Latar belakang: Sindroma Down adalah suatu kelainan congenital yang mudah dikenali, merupakan kelaian kromosom autosomal yang cukup banyak terjadi, dengan prevalensi maloklusi cukup tinggi.

    2012-01-01

    Full Text Available A myriad of ophthalmic disorders is associated with the phenotype of Down syndrome including strabismus, cataracts, and refractive errors potentially resulting in significant visual impairment. Ophthalmic sequelae have been extensively studied in children and adolescents with Down syndrome but less often in older adults. In-depth review of medical records of older adults with Down syndrome indicated that ophthalmic disorders were common. Cataracts were the most frequent ophthalmic disorder reported, followed by refractive errors, strabismus, and presbyopia. Severity of intellectual disability was unrelated to the presence of ophthalmic disorders. Also, ophthalmic disorders were associated with lower vision-dependent functional and cognitive abilities, although not to the extent that was expected. The high prevalence of ophthalmic disorders highlights the need for periodic evaluations and individualized treatment plans for adults with Down syndrome, in general, but especially when concerns are identified.

    Eucoleus boehmi (Nematoda: Capillariidae) occurs in the nasal conchae and paranasal sinuses of wild and domestic canids. We surveyed the red fox ( Vulpes vulpes ) on Prince Edward Island, Canada, for E. boehmi infection and characterized the associated histopathology. Nasal capillarid infections were detected based on histologic examination of three coronal sections of the nasal cavity and by centrifugal flotation examination (CFE) of rectal feces. Capillarids were detected in histologic sections in 28 of 36 (78%) foxes; detection occurred most frequently in the caudal section (28 foxes) and least in the rostral section (10 foxes). Adult worm morphology was typical for capillarids (stichosome esophagus, bacillary bands, bipolar plugged eggs); E. boehmi eggs were specifically identified based on the characteristic pitted shell wall surface. Adult worms were detected in histologic sections in all 28 and E. boehmi eggs in 21 of the positive foxes. No eggs of Eucoleus aerophilus were observed in any of the sections. Affected foxes had an eosinophilic and lymphoplasmacytic rhinitis with goblet cell hyperplasia. Eggs of E. aerophilus were detected on CFE in 20 of 36 (56%) foxes; 19 of the histologically positive foxes were coinfected with E. aerophilus. Eggs of E. boehmi were detected on CFE in 26 of 36 (72%) foxes and were consistent in size and morphology with those described from wild canids, but they differed from those reported from cases of infection in dogs. Prevalence based on identification of eggs on histologic section or CFE indicated 27 of 36 (75%) red foxes examined were infected with E. boehmi.

    Throughout the 1970s and 1980s, the Prince Edward Island Right to Life Association (RTLA) lobbied medical professionals, hospital boards, politicians, and neighbours to prevent the Charlottetown and Summerside hospital corporations, the only abortion providers on the Island, to eliminate their Therapeutic Abortion Committees. Because abortion committees were not mandatory and only hospital boards were responsible for establishing committees at accredited hospitals, the RTLA elected pro-life members to the boards and voted against abortion committee bylaws to establish barriers to abortion access. By holding key positions within the hospital corporations, pro-life activists ensured that abortion provisions were no longer legally or medically permissible in Island hospitals. This article draws on RTLA and government records, newspaper articles, as well as interviews with pro-life activists, to highlight the avenues through which the organization created a prominent social movement. By contesting the scientific reasoning for abortion, the RTLA quickly became a countermovement not only to the pro-choice movement, but also to the mainstream medical community.

    Current research suggests that pain is a relatively common phenomenon with 60-90% of patients presenting to emergency departments reporting pain (e.g., chest pain, trauma, extremity fractures and migraine headache) that require treatment [Hogan, S.L., 2005. Patient satisfaction with pain management in the emergency department. Advanced Emergency Nursing Journal 27(4), 284-294]. This article explores the use of conceptual theoretical empirical (C-T-E) framework to guide a senior nursing student in a case study of patient with chest pain. The Middle Range Theory of Pain described by Good [Good, M., 1998. A middle-range theory of acute pain management: use in research. Nursing Outlook 46(3), 120-124] and Melzack's [Melzack, R., 1987. The short-form McGill pain questionnaire. Pain, 30, 191-197] short form McGill pain questionnaire were applied along with the Prince Edward Island conceptual model (PEICM) for nursing. Results indicate that the nursing student increased her ability to work in partnership, assess relevant and specific information, and identify a number of strategies to help the patient achieve pain control by using a complement of pharmacological and non-pharmacological interventions. Moreover, the C-T-E approach provided an organized and systematic theoretical approach for the nursing student to assist a patient in pain control.

    Onion thrips (Thrips tabaci Lindeman (Thysanoptera: Thripidae)) can be a pest in organic onion production on Prince Edward Island. This study was to examine the effect of planting time and variety on infestation levels and damage by onion thrips on cabbage (Brassicae oleracea capitala (L.)). A field site was planted with 2 main and 8 lesser varieties of cabbage over 4 planting dates. Some varieties were short season and harvested on July 31 with longer season varieties harvested on September 2. Blue sticky traps were used to capture thrips migrating into the field site from July 22-September 2. Traps were counted weekly and cabbage heads within the field site were visually surveyed for thrips. At harvest, heads were weighed and measured, thrips damage was assessed then the head was dissected and thrips counted on the first four layers of the head. Thrips exhibited a preference for Lennox over Bronco throughout the season although thrips populations were not high enough to effect economic damage in 2014. Planting date influenced cabbage head weight and size with later plantings yielding the largest heads. Use of planting date and variety to avoid thrips populations is discussed.

    Full Text Available This is the first study to have examined the effect of smoking bans on hospitalizations in the Atlantic Canadian socio-economic, cultural and climatic context. On June 1, 2003 Prince Edward Island (PEI enacted a province-wide smoking ban in public places and workplaces. Changes in hospital admission rates for cardiovascular (acute myocardial infarction, angina, and stroke and respiratory (chronic obstructive pulmonary disease and asthma conditions were examined before and after the smoking ban.Crude annual and monthly admission rates for the above conditions were calculated from April 1, 1995 to December 31, 2008 in all PEI acute care hospitals. Autoregressive Integrated Moving Average time series models were used to test for changes in mean and trend of monthly admission rates for study conditions, control conditions and a control province after the comprehensive smoking ban. Age- and sex-based analyses were completed.The mean rate of acute myocardial infarctions was reduced by 5.92 cases per 100,000 person-months (P = 0.04 immediately after the smoking ban. The trend of monthly angina admissions in men was reduced by -0.44 cases per 100,000 person-months (P = 0.01 in the 67 months after the smoking ban. All other cardiovascular and respiratory admission changes were non-significant.A comprehensive smoking ban in PEI reduced the overall mean number of acute myocardial infarction admissions and the trend of angina hospital admissions.

    Full Text Available In the nineteenth century the image of Italy appealed also to Irish Romantic writers. But the way in which they naturalized the Italian alterity is quite ambivalent. On the one hand they filtered their images of the southern country through their relationship with England and thus ended up mirroring stereotypes common to the English-speaking world, and on the other hand they established a special, personal relationship with it shaped by their ideological and cultural differences from the British. This essay tackles the representations of Italy in two texts, namely Edward Maturin’s Bianca: A Tale of Erin and Italy, published in 1852, and in the earlier Italy (1821 by Lady Morgan. Both these works show that at that time there was a certain awareness, in Ireland, of the special historical and political conditions of Italy and of possible similarities with Ireland. Italy, oppressed by foreign domination yet aspiring to freedom, became a yardstick for gauging issues of subjugation, injustice, and national identity and invited sympathy from the citizens of a colonized country. Therefore, Italy was perceived as a mirror in which to reflect the Irish identity torn by aspirations which were hard to confess publicly or even to oneself.

    Full Text Available Abstract Background Late in the 1990s, the non-indigenous European green crab (Carcinus maenas colonized the shorelines of eastern Prince Edward Island, in Atlantic Canada. Due to concerns of further spread into productive shellfish habitats, an annual survey was conducted between 2000 and 2013 to detect a potential range expansion of this species. We compiled and analyzed that data and document green crab expansion using records of annual occurrence and relative density. Methods Surveys were conducted during the fall season of each year by deploying baited traps at 29 sites along the island’s two main shorelines (north and south shores. These sites were selected based on areas deemed more likely to be invaded by the green crab. Raw data per site and date was transformed to catch per unit effort (CPUE to estimate relative abundances. Results Populations of this species showed an uneven westward expansion along the north and south shores. Expansion rates changed among years but, overall, crab abundance was higher and changes in abundance were faster along the south shore than the north shore of the island. The westward expansion continues until this day. Conclusions Based on the information compiled we hypothesize that the dissimilarity in range expansion rate was related to the availability of suitable habitat to sustain large green crab populations along the south shore. We also discuss implications of this expansion for commercial shellfish and native coastal communities.

    2003-01-01

    Charles Edward Isaacs (1811-1860), an anatomist working in New York, undertook a series of studies which attempted to define the microscopic structure of the nephrons in a variety of species. Given that he published his findings 15 years after William Bowman's seminal paper on the subject, he was able to add only a few of the finer details to the picture. He observed the continuity of the epithelium of the glomerular capsule with that of the proximal tubule and he demonstrated that the glomerular tuft is covered by a layer of epithelial cells. In a series of studies on human renal function he erroneously concluded that the glomerulus must have an excretory function in addition to its filtration function and that diuretics act primarily on the glomerlus. The latter conclusion was based upon observations of substances not currently categorized as being diuretic agents. The absence of a major conceptual advance in the writings of Isaacs probably accounts for that fact that his contribution has been largely forgotten.

    The aim of this study was to investigate the mid-term haemodynamic and clinical results after aortic valve replacement (AVR) using the Sorin Freedom Solo (SFS) stentless bioprosthesis, compared with the standard Carpentier Edwards Perimount (CEP) stented bioprosthesis. In this retrospective cohort study of prospectively collected data, 116 patients were included in the SFS group (53 males; median age 74 years, range 56-85 years), and 122 patients in the CEP group (85 males; median age 73 years, range 43-88 years) between July 2007 and January 2013. Echocardiography was performed at 6 weeks after surgery in our centre, and the most recent echocardiography (in our centre or in referring cardiology departments) was requested. Between September 2013 and April 2014, all patients were called by the same researcher to gain clinical follow-up data. Mid-term mortality was 16.4% in the SFS group (19 patients) and 21.3% in the CEP group (26 patients); (P = 0.3).

    The landing of the ROSETTA-mission lander Philae on November 12th 2014 on Comet 67 P/Churyumov-Gerasimenko was planned as a descent with passive landing and anchoring by harpoons at touch-down. Actually the lander was not fixed at touch-down to the ground due to failing harpoons. The lander internal damper was actuated at touch-down for 42.6 mm with a speed of 0.08 m/s while the lander touch-down speed was 1 m/s. The kinetic energy before touch-down was 50 J, 45 J were dissipated by the lander internal damper and by ground penetration at touch-down, and 5 J kinetic energy are left after touch-down (0.325 m/s speed). Most kinetic energy was dissipated by ground penetration (41 J) while only 4 J are dissipated by the lander internal damper. Based on these data, a value for a constant compressive soil-strength of between 1.55 kPa and 1.8 kPa is calculated. This paper focuses on the reconstruction of the touch-down at Agilkia over a period of around 20 s from first ground contact to lift-off again. After rebound Philae left a strange pattern on ground documented by the OSIRIS Narrow Angle Camera (NAC). The analysis shows, that the touch-down was not just a simple damped reflection on the surface. Instead the lander had repeated contacts with the surface over a period of about 20 s±10 s. This paper discusses scenarios for the reconstruction of the landing sequence based on the data available and on computer simulations. Simulations are performed with a dedicated mechanical multi-body model of the lander, which was validated previously in numerous ground tests. The SIMPACK simulation software was used, including the option to set forces at the feet to the ground. The outgoing velocity vector is mostly influenced by the timing of the ground contact of the different feet. It turns out that ground friction during damping has strong impact on the lander outgoing velocity, on its rotation, and on its nutation. After the end of damping, the attitude of the lander can be

    In August 2007, the U.S. Geological Survey, in cooperation with the San Antonio Water System, did a hydrogeologic and geophysical investigation to characterize the hydrostratigraphy (hydrostratigraphic zones) and also the hydrogeologic features (karst features such as sinkholes and caves) of the Edwards aquifer in a 16-square-kilometer area of northeastern Bexar County, Texas, undergoing urban development. Existing hydrostratigraphic information, enhanced by local-scale geologic mapping in the area, and surface geophysics were used to associate ranges of electrical resistivities obtained from capacitively coupled (CC) resistivity surveys, frequency-domain electromagnetic (FDEM) surveys, time-domain electromagnetic (TDEM) soundings, and two-dimensional direct-current (2D-DC) resistivity surveys with each of seven hydrostratigraphic zones (equivalent to members of the Kainer and Person Formations) of the Edwards aquifer. The principal finding of this investigation is the relation between electrical resistivity and the contacts between the hydrostratigraphic zones of the Edwards aquifer and the underlying Trinity aquifer in the area. In general, the TDEM data indicate a two-layer model in which an electrical conductor underlies an electrical resistor, which is consistent with the Trinity aquifer (conductor) underlying the Edwards aquifer (resistor). TDEM data also show the plane of Bat Cave fault, a well-known fault in the area, to be associated with a local, nearly vertical zone of low resistivity that provides evidence, although not definitive, for Bat Cave fault functioning as a flow barrier, at least locally. In general, the CC resistivity, FDEM survey, and 2D-DC resistivity survey data show a sharp electrical contrast from north to south, changing from high resistivity to low resistivity across Bat Cave fault as well as possible karst features in the study area. Interpreted karst features that show relatively low resistivity within a relatively high

    Down syndrome affects more than 5 million people globally. During the last 10 years, there has been a dramatic increase in the research efforts focused on therapeutic interventions to improve learning and memory in Down syndrome. This review summarizes the different functional abnormalities targeted by researchers in mouse models of Down syndrome. Three main strategies have been used: neural stem cell implantation; environmental enrichment and physical exercise; and pharmacotherapy. Pharmacological targets include the choline pathway, GABA and NMDA receptors, DYRK1A protein, oxidative stress and pathways involved in development and neurogenesis. Many strategies have improved learning and memory as well as electrophysiological and molecular alterations in affected animals. To date, eight molecules have been tested in human adult clinical trials. No studies have yet been performed on infants. However, compelling studies reveal that permanent brain alterations originate during fetal life in Down syndrome. Early prenatal diagnosis offers a 28 weeks window to positively impact brain development and improve postnatal cognitive outcome in affected individuals. Only a few approaches (Epigallocatechine gallate, NAP/SAL, fluoxetine, and apigenin) have been used to treat mice in utero; these showed therapeutic effects that persisted to adulthood. In this article, we discuss the challenges, recent progress, and lessons learned that pave the way for new therapeutic approaches in Down syndrome.

    We present additional clinical evidence for the suspected association of Down's syndrome and testicular germ cell tumors. Four cases of Down's syndrome and testicular cancer are reported. The literature was reviewed for previous cases and analysis regarding common features. The 4 patients were 29 to 35 years old and had clinical stage I seminoma of the testis. Two patients received prophylactic abdominal radiotherapy, 1 is being followed and 1 received adjuvant carboplatin treatment. There was no relapse at followup of 1 to 8 years. One patient also had contralateral cryptorchidism. A total of 16 cases with the association of Down's syndrome and testicular germ cell cancer was documented previously. Evidence for the suspected association of Down's syndrome and testicular cancer is now accumulating. Etiologically it is suspected that, along with genetically determined malformations in many other organs in trisomy 21, the gonads also undergo maldevelopment, thus creating the conditions for step 1 of germ cell tumor oncogenesis in utero. Physicians caring for patients with Down's syndrome should be aware of the possible association with testicular neoplasms.

    The Edwards Lifesciences Prima Plus stentless valve (ELSV) is a bioprosthesis manufactured from a porcine aortic root. The study aim was to evaluate late clinical outcomes after aortic valve replacement (AVR) with ELSV implanted as a miniroot in patients with aortic valve disease. Between 1993 and 2004, 318 patients (232 males, 86 females; mean age 69 +/- 9 years; range: 37-83 years) underwent AVR with the ELSV. Preoperatively, 102 patients (32%), 162 (51%) and 54 (17%) were in NYHA classes I/II, III and IV, respectively. Aortic stenosis, aortic regurgitation and combined lesions were present in 124 patients (39%), 114 (36%) and 41 (13%), respectively. Twenty patients (6%) were referred for an acute aortic dissection, 20 (6%) for an aortic root aneurysm, and 139 (44%) had an associated aneurysmal dilatation of the ascending aorta. The ascending aorta was replaced in 159 patients (50%); aortic arch replacement was required in 10 (3%). Coronary artery bypass graft was performed in 86 patients (27%). The follow up was based on clinical data. Operative mortality was 5% (n = 17). There were 49 late deaths (5.2%/pt-yr). Valve-related mortality occurred in 10 patients (1%/pt-yr). Actuarial survival at five and 10 years was 78% and 33%, respectively. Actuarial freedom from valve reoperation and structural valve deterioration at 10 years were 100% and 64%. Actuarial freedom from embolic events and endocarditis at 10 years were 84% and 81%, respectively. The ELSV, when implanted as a miniroot, provided good early and long-term results in terms of survival and freedom from major complications.

    Full Text Available O artigo propõe uma leitura do trabalho do teórico pós-colonial Edward Said por meio de um olhar bakhtiniano. Ainda que Said e Bakhtin tenham se engajado de forma diferente na política de suas respectivas épocas e que tivessem ideias distintas sobre a relação entre ética e política, seus escritos abrangentes têm sido adaptados e suas ideias apropriadas por estudiosos em diferentes áreas - com frequência, as mesmas. Eles compartilharam a paixão pelo diálogo, explorando a alteridade e a exotopia, e acreditando na responsa-habilidade. O que o romance era para Bakhtin, o pianismo era para Said, como crítico musical. Said nunca desempenhou o papel de guia do consumidor ou de guardião. Era antes o par crítico ou o professor que atribui menções. A variedade de possíveis respostas do público sempre condicionou as suas. Em toda sua vida musical Said pensou como Bakhtin, talvez sem saber disso. As críticas musicais de Said eram, por definição, respostas ou réplicas. Eram híbridas, narrações e transmissões bivocais, mas também apropriações, como eram os romances aos olhos de Bakhtin. Os escritos de Said sobre música foram analisados à luz de vários conceitos-chaves de Bakhtin: dialogismo, endereçamento, responsa-habilidade e o papel do contexto.

    The association of organisms with particular habitats and habitat-forming organisms, can strongly influence species distributions, interactions and wider ecosystem services. At the sub-Antarctic Prince Edward Islands, the caridean shrimp Nauticaris marionis is a principal part of the benthic ecosystem, occurring between ca. 50 m and 600 m. Its role as a trophic link between the primary productivity and higher predators is established, but little is understood of its in situ habitat usage and associations or of how these structure patterns of abundance. We investigated these aspects directly using a benthic camera sled, sampling 27 stations between 50 m and 500 m. Substratum type was characterised, and estimates of percentage cover of the 13 main groups of habitat-forming epibenthic taxa were made, alongside absolute counts of N. marionis within 'digital quadrats' drawn from 300 m transects. The distribution of N. marionis was influenced by depth, substratum type and overall biogenic cover, being limited to habitats between 50 and 160 m depth on mud or gravel substrata only, and having > 50% biogenic cover. The presence/absence of N. marionis related to significantly different epibenthic assemblages (termed biogenic habitats), but this effect was contingent on depth. Likewise, densities of N. marionis were significantly affected by biogenic habitat type, identifying an association with two biogenic habitat groups, one dominated by red-algae, the other by structurally complex bryozoan species. These associations likely relate to the structural complexity of the two habitat groups, rather than the specific taxa involved. The apparent absence of N. marionis at depths > 160 m contrasts with earlier records and poses questions about the trophic importance of the shrimp in deeper habitats.

  5. Judging Edward Teller: A Closer Look at One of the Most Influential Scientists of the Twentieth Century

    2010-12-29

    Much has been written about Edward TEller, but little of it is objective. Given, on the one hand, his position as one of the most inventive theoretical physicists of the 20th century, and on the other, his central role in the development and advocacy of thermonuclear weapons, one might imagine it impossible at this point in history to write a scholarly, impartial account of Teller's life and his impact. Now, however, Istvan Hargittai, a prominent Hungarian physical chemist and historian of science, has written a balanced, thoughtful, and beautifully research biography that comes closest. Hargittai is uniquely qualified for this difficult task. Coming a generation and a half later from a similar Hungarian-Jewish background, Hargittai understands well the influences and terrible events that shaped Teller. The advent of virulent, political anti-Semitism, first in Hungary and then in Germany, made Teller twice a refugee. Both Teller and Hargittai lost close family in the Holocaust; Hargittai was himself liberated from a Nazi concentration camp as a child. While Teller was in the US by then, his and Hargittai's surviving family members in Hungary suffered mistreatment at the hands of the postwar Hungarian Communist dictatorship. Hargittai's informed Eastern European perspective also provides a fresh viewpoint to the cold war context of the second half of Teller's career. Furthermore, Hargittai's own scientific work in molecular structure clearly makes him appreciate of Teller's breakthroughs in that field in the 1930s.

    To minimize the risk posed by runoff from row crops, Prince Edward Island introduced buffer legislation in 2000. The legislation mandates 10-m and 20-m buffers, respectively, for moderate sloped (i.e. 5%) agricultural fields that border streams. Since 2001, Environment Canada has been evaluating the effectiveness of various buffer widths on operational farms in reducing toxicity and contaminant concentrations in runoff. Sample collectors, placed in 44 fields at the field edge (0m), 10m and at distances out to 30m, collected overland flow following rainfall-induced runoff events. Samples were collected within 24 hours of an event and analysed for seven pesticides (endosulfan, chlorothalonil, carbofuran, linuron, metribuzin, metalaxyl, mancozeb), water quality parameters and Daphnia magna toxicity. The 10-m buffer required for moderate sloped fields was effective at reducing contaminant concentrations but not always to less than lethal concentrations to Daphnia magna. Limited data beyond 10m for fields of both slope types precluded making recommendations on a suitable buffer width for shallow sloped fields and evaluating the effectiveness of 20-m buffers for steep sloped fields. When paired data were combined and statistically tested for all fields, the studied pesticides underwent a 52-98% and 68-100% reduction in aqueous and particulate concentrations within 10m and 30m, respectively. In addition, by 10m, soluble phosphorus, nitrate-nitrogen and total suspended solids were reduced by 34%, 38% and 64%, respectively. Results suggest buffer zones on operational farms are capable of achieving contaminant reductions comparable to those reported for controlled experiments. Inconsistent siting of sample collectors beyond 10m limited the evaluation of the effects of field slope and buffer width on buffer effectiveness on working farms. Future studies on buffer efficiency on operational farms should focus on building the data set beyond 10m and evaluating load reductions

    We formulate the neutron slowing-down time through elastic collisions in a homogeneous, non-absorbing, infinite medium. Our approach allows taking into account for the first time the energy dependence of the scattering cross-section as well as the energy and temporal distribution of the source neutron population in the results. Starting from this development, we investigate the specific case of the propagation in matter of a mono-energetic neutron pulse. We then quantify the perturbation on the neutron slowing-down time induced by resonances in the scattering cross-section. We show that a resonance can induce a permanent reduction of the slowing-down time, preceded by two discontinuities: a first one at the resonance peak position and an echo one, appearing later. From this study, we suggest that a temperature increase of the propagating medium in presence of large resonances could modestly accelerate the neutron moderation.

    Objective: To evaluate the effect of preimplantation genetic diagnosis (PGD) conducted for women who had Down syndrome pregnancy previously. Methods: Trisomy 21 was diagnosed by using fluorescence in site hybridization (FISH) before embryo transfer in two women who had Down syndrome pregnancies. Each received one or two PGD cycles respectively. Results:Case 1: one PGD cycle was conducted, two oocytes were fertilized and biopsied. One embryo is of trisomy 21 and the other of monosomy 21. No embryo was transferred. Case 2: two PGD cycles were conducted, in total, sixteen oocytes were fertilized and biopsied. Four embryos were tested to be normal, six of trisomy 21, and one of monosomy 21. Five had no signal. Four normal embryos were transferred but no pregnancy resulted. Conclusion: For couples who had pregnancies with Down syndrome previously, PGD can be considered, and has been shown to be an effective strategy.

    The microelectronics evolution has given rise to many modern benefits but has also changed design methods and attitudes to learning. Technology advancements shifted focus from simple circuits to complex systems with major attention to high-level descriptions. The design methods moved from a bottom-up to a top-down approach. For today's students, the most beneficial approach to learning is this top-down method that demonstrates a global view of electronics before going into specifics. Franco Maloberti uses this approach to explain the fundamentals of electronics, such as processing functions,

    As the cost of whole genome analysis decreases, we have the opportunity to explore the interactions of various gene changes in an individual that lead to their particular phenotype. This will provide the ability to move from the epidemiologic study of groups, in which, the individuals are treated collectively and homogenously, to personalized medicine, and a model in which the individual is recognized and treated as a distinct entity. We will be applying personalized medicine to individuals with Down syndrome in order to understand and develop biomarkers for increased risk of co-morbidities. Personalized medicine will change the "culture of intractability" of Down syndrome. Copyright © 2011 Elsevier Inc. All rights reserved.

    As the final LS1 activities are carried out in the machine, teams have been cooling down the accelerator sector by sector in preparation for beams.   The third sector of the LHC to be cooled down - sector 1-2 - has seen the process begin this week. During the cool-down phase, survey teams are measuring and smoothing (or realigning) the magnets at cold. By the end of August, five sectors of the machine will be in the process of cooling down, with one (sector 6-7) at cold. The LHC Access Safety System (LASS) is now being commissioned, and will be validated during the DSO tests at the beginning of October. As teams consolidate the modifications made to LASS during the shutdown, many points were closed for testing purposes. The CSCM (copper stabiliser continuity measurement) tests have been completed in the first sector (6-7) and no defect has been found. These results will be presented to the LHC Machine Committee next week. CSCM tests will start in the second sector in mid-August. Following many...

  3. Analysis of the neutron slowing down equation

    International Nuclear Information System (INIS)

    Sengupta, A.; Karnick, H.

    1978-01-01

    The infinite series solution of the elementary neutron slowing down equation is studied using the theory of entire functions of exponential type and nonharmonic Fourier series. It is shown from Muntz--Szasz and Paley--Wiener theorems, that the set of exponentials ]exp(ilambda/sub n/u) ]/sup infinity//sub n/=-infinity, where ]lambda/sub n/]/sup infinity//sub n/=-infinity are the roots of the transcendental equation in slowing down theory, is complete and forms a basis in a lethargy interval epsilon. This distinctive role of the maximum lethargy change per collision is due to the Fredholm character of the slowing down operator which need not be quasinilpotent. The discontinuities in the derivatives of the collision density are examined by treating the slowing down equation in its differential-difference form. The solution (Hilbert) space is the union of a countable number of subspaces L 2 (-epsilon/2, epsilon/2) over each of which the exponential functions are complete

    To assess the rates of incontinence and associated psychological problems in children, adolescents and adults with Down Syndrome, a genetic syndrome caused by partial or complete triplication (trisomy) of chromosome 21 and characterized by typical facial features, a physical growth delay and mild or moderate intellectual disability. Three hundred and seventeen persons with Down Syndrome (4-51 years) were recruited through a German parent support group (59.6% male, mean age 19.2 years). The Parental Questionnaire: Enuresis/Urinary Incontinence, the Incontinence Questionnaire-Pediatric Lower Urinary Tract Symptoms, as well as the Developmental Behavior Checklist (DBC) for parents or for adults were filled out by parents or care-givers. 17.2% of the sample had nocturnal enuresis, 15.9% had daytime urinary incontinence, and 14.2% had fecal incontinence. Incontinence was present in 64.0% of young children (4-12 years), 10.3% of teens (13-17 years), 12.8% of young adults (18-30 years) and in 22.4% of older adults (>30 years). 13.6% of children and 8.4% of adults had a DBC score in the clinical range. 19.5% of children and 27.8% of adults with incontinence had behavioral problems. There was a significant association between nocturnal enuresis, daytime urinary incontinence and clinical DBC scores in adults. Incontinence in Down Syndrome is mainly present in young children and increases in older adults. Behavioral comorbidity is associated with incontinence only in adults with Down Syndrome. Screening and treatment of incontinence in individuals with Down Syndrome is recommended. © 2016 Wiley Periodicals, Inc.

  7. Integrating urban recharge uncertainty into standard groundwater modeling practice: A case study on water main break predictions for the Barton Springs segment of the Edwards Aquifer, Austin, Texas

    Sinner, K.; Teasley, R. L.

    2016-12-01

    Groundwater models serve as integral tools for understanding flow processes and informing stakeholders and policy makers in management decisions. Historically, these models tended towards a deterministic nature, relying on historical data to predict and inform future decisions based on model outputs. This research works towards developing a stochastic method of modeling recharge inputs from pipe main break predictions in an existing groundwater model, which subsequently generates desired outputs incorporating future uncertainty rather than deterministic data. The case study for this research is the Barton Springs segment of the Edwards Aquifer near Austin, Texas. Researchers and water resource professionals have modeled the Edwards Aquifer for decades due to its high water quality, fragile ecosystem, and stakeholder interest. The original case study and model that this research is built upon was developed as a co-design problem with regional stakeholders and the model outcomes are generated specifically for communication with policy makers and managers. Recently, research in the Barton Springs segment demonstrated a significant contribution of urban, or anthropogenic, recharge to the aquifer, particularly during dry period, using deterministic data sets. Due to social and ecological importance of urban water loss to recharge, this study develops an evaluation method to help predicted pipe breaks and their related recharge contribution within the Barton Springs segment of the Edwards Aquifer. To benefit groundwater management decision processes, the performance measures captured in the model results, such as springflow, head levels, storage, and others, were determined by previous work in elicitation of problem framing to determine stakeholder interests and concerns. The results of the previous deterministic model and the stochastic model are compared to determine gains to stakeholder knowledge through the additional modeling

    Intensive farming of potatoes in Prince Edward Island (PEI) relies on the repeated and widespread application of fertilizers and pesticides. In PEI the main potato farming areas are in close proximity and drain directly to estuaries. Runoff from high agricultural activity watersheds could impact benthic organism health in the depositional zone of downstream estuaries. The estuarine filter feeder Mya arenaria (soft-shell clam) could be particularly vulnerable to both particle-adsorbed and water soluble contaminants. M. arenaria is susceptible to haemocytic leukemia. In May 2009, we established that heavily proliferated leukemia (HPL) prevalence was generally higher in PEI estuaries located downstream of high intensity potato farming (Dunk and Wilmot estuaries) watersheds than in estuaries downstream of lower intensity areas. Using Mab-1E10 based immunocytochemistry we observed that leukemic haemocytes from the Dunk and Wilmot estuaries were 1E10 negative whereas those from the Ox/Sheep estuary (low potato farming intensity) were 1E10 positive. The expression of genes in the p53 tumour suppressor pathway enabled us to differentiate groups of leukemic and normal M. arenaria, validating our diagnoses. In October 2009, we confirmed that HPL prevalence was elevated in the Dunk and Wilmot estuaries compared to reference (Souris River). Moreover, leukemia prevalence declined with distance from the river mouths along transects through the Dunk and Wilmot estuaries. The pesticides ß-endosulfan and α-endosulfan were detected in surface sediments from the Dunk and Wilmot estuaries, but not in sediments from either the Souris River or several other lower intensity potato farming watersheds. Our study provides evidence of an association between intensity of potato farming and prevalence of clam leukemia at downstream estuaries in PEI. - Highlights: ► We examined leukemia prevalence in PEI clams Mya arenaria. ► Prevalence was generally higher downstream of high intensity

    This paper examines the social thought of University of Wisconsin professors Richard T. Ely, John R. Commons, and Edward A. Ross during World War I. Like many of their fellow scholars, these three were actively involved in the pro-war effort. Although their support for the war was strongly conditioned by personal and occupational considerations, the impact of their wartime service was not restricted to those realms. Their social thought, which they impressed into service explaining and justifying the war, was itself altered in subtle and sometimes surprising ways by the forceful positions they took on the political, economic, and racial significance of the conflict.

    We put forward a framework for cosmology that combines the string landscape with no boundary initial conditions. In this framework, amplitudes for alternative histories for the universe are calculated with final boundary conditions only. This leads to a top down approach to cosmology, in which the histories of the universe depend on the precise question asked. We study the observational consequences of no boundary initial conditions on the landscape, and outline a scheme to test the theory. This is illustrated in a simple model landscape that admits several alternative inflationary histories for the universe. Only a few of the possible vacua in the landscape will be populated. We also discuss in what respect the top down approach differs from other approaches to cosmology in the string landscape, like eternal inflation.

    We explore holographic entanglement entropy in ten-dimensional supergravity solutions. It has been proposed that entanglement entropy can be computed in such top-down models using minimal surfaces which asymptotically wrap the compact part of the geometry. We show explicitly in a wide range of examples that the holographic entanglement entropy thus computed agrees with the entanglement entropy computed using the Ryu-Takayanagi formula from the lower-dimensional Einstein metric obtained from reduction over the compact space. Our examples include not only consistent truncations but also cases in which no consistent truncation exists and Kaluza-Klein holography is used to identify the lower-dimensional Einstein metric. We then give a general proof, based on the Lewkowycz-Maldacena approach, of the top-down entanglement entropy formula.

    In developed countries the population of elderly people with Down syndrome expands resulting in an increasing incidence of age-related diseases, including dementia. The assessment of dementia in individuals with intellectual disability is often complicated due to large intra-individual variability...... in cognitive functioning prior to dementia and to lack of standardised measures to detect dementia. Structured observations of symptoms of dementia and assessment techniques tailored for people with intellectual disability are increasingly needed....

    Full Text Available We present the preliminary tests on two modifications of the Hybrid Monte Carlo (HMC algorithm. Both algorithms are designed to travel much farther in the Hamiltonian phase space for each trajectory and reduce the autocorrelations among physical observables thus tackling the critical slowing down towards the continuum limit. We present a comparison of costs of the new algorithms with the standard HMC evolution for pure gauge fields, studying the autocorrelation times for various quantities including the topological charge.

  6. Years of life lost through Down's syndrome.

    A congenital genetic condition does not act either as a cause of death or at the time of death only. Hence, years of life lost through such a conditon cannot be calculated in the same way as for a conventional cause of death. The main difference is that a cause of death acting at age x cuts off as many years of life as the dead person might otherwise have expected to live (life expectancy at age x), whereas a congenital genetic condition exposes an affected person to a different schedule of life-threatening risks from birth onwards. In the latter case, years of life lost is calculated as the difference in life expectancy at birth for affected and non-affected persons. This reasoning is worked out in algebraic form and then applied to Down's syndrome. The data base is provided by two large and recent studies, one in Massachusetts and the other in Denmark, of mortality rates among all cases of Down's syndrome, whether in an institution or not, born during a given period of years or living at a given point in time in a fixed geographical area. So calculated, years of life lost through Down's syndrome relative to the United States general population in 1970 was 53.6 years per 1000 livebirths. Prenatal mortality is also discussed.

    Highlights: • Top Down versus Bottom Up proteomics analysis. • Separations methods for Top Down proteomics. • Developments in mass spectrometry instrumentation and fragmentation. • Native mass spectrometry. - Abstract: The rise of the “Top Down” method in the field of mass spectrometry-based proteomics has ushered in a new age of promise and challenge for the characterization and identification of proteins. Injecting intact proteins into the mass spectrometer allows for better characterization of post-translational modifications and avoids several of the serious “inference” problems associated with peptide-based proteomics. However, successful implementation of a Top Down approach to endogenous or other biologically relevant samples often requires the use of one or more forms of separation prior to mass spectrometric analysis, which have only begun to mature for whole protein MS. Recent advances in instrumentation have been used in conjunction with new ion fragmentation using photons and electrons that allow for better (and often complete) protein characterization on cases simply not tractable even just a few years ago. Finally, the use of native electrospray mass spectrometry has shown great promise for the identification and characterization of whole protein complexes in the 100 kDa to 1 MDa regime, with prospects for complete compositional analysis for endogenous protein assemblies a viable goal over the coming few years.

  8. Design of scaled down structural models

    1994-07-01

    In the aircraft industry, full scale and large component testing is a very necessary, time consuming, and expensive process. It is essential to find ways by which this process can be minimized without loss of reliability. One possible alternative is the use of scaled down models in testing and use of the model test results in order to predict the behavior of the larger system, referred to herein as prototype. This viewgraph presentation provides justifications and motivation for the research study, and it describes the necessary conditions (similarity conditions) for two structural systems to be structurally similar with similar behavioral response. Similarity conditions provide the relationship between a scaled down model and its prototype. Thus, scaled down models can be used to predict the behavior of the prototype by extrapolating their experimental data. Since satisfying all similarity conditions simultaneously is in most cases impractical, distorted models with partial similarity can be employed. Establishment of similarity conditions, based on the direct use of the governing equations, is discussed and their use in the design of models is presented. Examples include the use of models for the analysis of cylindrical bending of orthotropic laminated beam plates, of buckling of symmetric laminated rectangular plates subjected to uniform uniaxial compression and shear, applied individually, and of vibrational response of the same rectangular plates. Extensions and future tasks are also described.

    Medical technology makes an inevitable trend for the elderly population, therefore the intelligent home care is an important direction for science and technology development, in particular, elderly in-home safety management issues become more and more important. In this research, a low of operation algorithm and using the triangular pattern rule are proposed, then can quickly detect fall-down movements of humanoid by the installation of a robot with camera vision at home that will be able to judge the fall-down movements of in-home elderly people in real time. In this paper, it will present a preliminary design and experimental results of fall-down movements from body posture that utilizes image pre-processing and three triangular-mass-central points to extract the characteristics. The result shows that the proposed method would adopt some characteristic value and the accuracy can reach up to 90 % for a single character posture. Furthermore the accuracy can be up to 100 % when a continuous-time sampling criterion and support vector machine (SVM) classifier are used.

    Heading AbstractAims. To describe the craniofacial morphology of a group of patients with Down's syndrome using a cephalometric analysis of the lateral skull radiograph.Materials and methods. The studied sample consisted of 39 patients with Down's syndrome (24 boys, 15 girls) ranging from 7 to 18 years of age. The computerized cephalometric study of the lateral skull radiograph of each patient was carried out using the method described by Ricketts.Results.Anterior cross-bite was observed in 38.4% of patients and diminished interincisal angle in 77%. Skeletal parameters matched the clinical norm, indicating mesofacial biotype, i.e., normal maxillomandibular growth. The lower incisors protruded in 84.6% of the individuals studied and were proinclined in 77%; upper incisors were protruded in 77% of the sample. The lower lip protruded in 84.6%. Analysis of craniofacial parameters showed average values within the clinical norm. Analysis of the inner cranium demonstrated normal inclination of the cranial base, while the length of the anterior skull base was diminished in 53.8%.Conclusions. From the skeletal perspective, patients with Down's syndrome who are in a period of growth demonstrate a reduction of the anterior skull base. From the dentoalveolar perspective, they show protrusion and proinclination of lower incisors, which is related to a tendency to anterior cross-bite and, to a lesser extent, to diminished overbite. Likewise, the lower lip protrusion observed in this study is related to the position of the lower incisor. (orig.)

    Present efforts to identify, isolate, and characterize in molecular terms the "consensus" segment of 21q sufficient to cause most of the major and some of the most characteristic minor manifestations of Down syndrome will soon provide answers to many questions. However, we think that a reductionist approach to explain the Down syndrome phenotype in a "linear" manner from the DNA sequence of the segment will be doomed to failure from the outset because of the open, complex, nonlinear, hierarchical nature of morphogenetic systems. Neo-Darwinism is under strong attack; most genetic changes accumulated over time may very well be of neutral effect, and detailed studies in several related groups of vertebrate species has shown that molecular and organismal evolution are largely independent of one another. It has been pointed out recently that biology lacks a theory of ontogenetic and phylogenetic development, and that a purely "genocentric" view of biology at the expense of the complexly hierarchical intrinsic epigenetic attributes of developmental systems is "out of focus with respect to ... biological organization and morphogenesis," and may be "a residue of nineteenth century romantic idealism." Down syndrome impresses us as a paradigm of increased developmental variability due to a deceleration of the rate of development (neoteny) with many anomalies of incomplete morphogenesis (vestigia), atavisms, increased morphometric variability with many decreased means, increased variances, and increased fluctuating asymmetry. These abnormalities, together with highly increased risk of prenatal death and postnatal morbidity, impaired growth, and abnormal CNS and gonadal structure and function characteristic of most aneuploidy syndromes, suggest to us that the pathogenesis of Down syndrome is best viewed in terms of the mechanisms of speciation. Transgenic experiment involving sequential or overlapping pieces of "the consensus segment" on distal 21q22.1-22.3 may help decide to

    The aim of this study was to determine the frequency of fecal carriage of vancomycin-resistant Enterococcus spp. and Escherichia coli with reduced susceptibilities to extended-spectrum cephalosporins (ESCs) and quinolones in humans on Prince Edward Island, Canada. Convenience fecal samples from individuals on Prince Edward Island were screened phenotypically using selective culture and genotypically using multiplex polymerase chain reactions to detect E. coli and Enterococcus spp. resistant to critically important antimicrobials. Twenty-six (5.3%) of 489 individuals had E. coli with reduced susceptibility to ESCs. Twenty-five (96.2%) of the 26 isolates harbored bla TEM , 18 (69.2%) harbored bla CMY-2 , 16 (61.5%) harbored bla CTX-M groups, 2 (7.7%) harbored bla SHV genes. None of the ESC-resistant E. coli was positive for carbapenem resistance. Twenty-one (8.3%) of 253 individuals had E. coli isolates with reduced quinolone susceptibility. All 21 isolates were positive for at least 1 qnr gene, with 3 (14.3%) isolates positive for qnrB, 5 (23.8%) positive for qnrS, and 13 (61.9%) positive for both qnrB and qnrS genes. All the enterococci isolates were vancomycin-susceptible. Higher susceptibility to the critically important antimicrobials was found in this study. This study can serve as a baseline for future antimicrobial resistance surveillance within this region.

    Severe anaphylactoid reaction after the use of iodinated contrast media are rare but can contraindicate the use of contrast agent. It was the case of a 53-year-old woman suffering from symptomatic severe aortic stenosis, recused for cardiac surgery because of deleterious effects of chest-wall irradiation, with porcelain aorta. We decided to implant a 23-mm Edwards(®) SAPIEN(®) transcatheter aortic valve via a femoral route without using any contrast media. The implantation was successful after surgical approach of the femoral artery, transesophageal echocardiography guiding, and localization of native leaflets and coronary trunk with catheters. Immediate and one month post-interventional follow-up was favorable and echocardiography showed a good functioning of the aortic bioprosthesis. Although conventional angiography is the best way to visualize the good positioning of the valve before deployment, our case suggests that, in special situations, transfemoral implantation of an Edwards(®) SAPIEN(®) aortic bioprosthesis is feasible without any contrast injection.

    We introduce a scattering-type scanning near-field infrared microscope (s-SNIM) for the local scale near-field sample analysis and spectroscopy from room temperature down to liquid helium (LHe) temperature. The extension of s-SNIM down to T = 5 K is in particular crucial for low-temperature phase transitions, e.g., for the examination of superconductors, as well as low energy excitations. The low temperature (LT) s-SNIM performance is tested with CO2-IR excitation at T = 7 K using a bare Au reference and a structured Si/SiO2-sample. Furthermore, we quantify the impact of local laser heating under the s-SNIM tip apex by monitoring the light-induced ferroelectric-to-paraelectric phase transition of the skyrmion-hosting multiferroic material GaV4S8 at Tc = 42 K. We apply LT s-SNIM to study the spectral response of GaV4S8 and its lateral domain structure in the ferroelectric phase by the mid-IR to THz free-electron laser-light source FELBE at the Helmholtz-Zentrum Dresden-Rossendorf, Germany. Notably, our s-SNIM is based on a non-contact atomic force microscope (AFM) and thus can be complemented in situ by various other AFM techniques, such as topography profiling, piezo-response force microscopy (PFM), and/or Kelvin-probe force microscopy (KPFM). The combination of these methods supports the comprehensive study of the mutual interplay in the topographic, electronic, and optical properties of surfaces from room temperature down to 5 K.

I have not found anyone who believes that there was really frost! The Australian welcome did its best to combat the cold, however, and Professor Rod Jury had soon introduced our guides and got us settled in on the campus of Canberra University. The British team of five students, selected through the British Physics Olympiad, were: Alan Bain of Birkenhead School, Chris Blake of King Edward VI School, Southampton, Richard Davies of Dulwich College, Tom Down of Embley Park School, Romsey and Chris Webb of Royal Grammar School, Worcester. The two Leaders of the party were Cyril Isenberg of the University of Kent and Guy Bagnall of Harrow School. Chris Robson of St Bee's School and myself from Stoke on Trent Sixth form College were interested Observers and Guy's wife, Jenny, completed the party. For the old hands there were many friendships stretching back years to renew, and with 51 countries this year many new ones to be made. Â Photo Figure 1. Photograph taken by C Robson of the British Physics Team immediately after the Awards Ceremony in Canberra in July 1995.

In addition to the confusion caused by the Sun being in the North and the Moon appearing to lie on its back, we had to get used to the flocks of chattering parrots browsing on the lawns and the kangaroos on campus! Everyone was presented with a boomerang and there were several sessions introducing the art of throwing them, even in the dark! The Opening Ceremony was colourful and a good mix of ceremony and fun with the Aboriginal entertainment and the Flame of Science to be lit. This was followed by my first examiners' meeting. Once the questions have been introduced no one is allowed to leave the group until ten hours later when the students are in bed! The

    Asymptomatic idiopathic condylar resorption is a rare disease of difficult diagnosis and treatment. We review the literature about this rare condition and report a case of a patient, affected by Down syndrome, who underwent a complete untreated bilateral condylar resorption in adolescence and then developed pain on chewing only 20 years later. Despite a precise orthodontic and surgical therapeutic plan, treatment had to be discontinued because of patient lack of compliance. This case is the first of its kind to be reported and emphasizes the need for special attention in patients with disability.

    Full Text Available Objective: To determine phonological processing in elemantery children with Down syndrome Materials and Methods: Phonetic test is used to extract phonological processing in 40 child with Down syndrome .They were normal in hearing and oral structure. Results: There was significant difference between girls and boys in some subgroups of phonological processing. In assimilation, voiceless assimilation in boys and complete assimilation in girls were the most. Nasal assimilation in girls and fricative assimilation in boys were the least. In substitution, the least mean belonged to liquid and nasal substitution in girls and voice ness substitution in boys. In general there was no significant difference between age and phonological awareness; however, there was direct correlation between syllable structure and age and reverse correlation between age and stop assimilation. Conclusion: In addition to 3 groups of phonological processing including: syllable structure, assimilation, and substitution, omission was seen. The difference between girls and boys indicates they are impressed by the phonetic structure of words in different ways. Correlation between age and phonological processing shows phonological errors may be resulted from deviation.

    Full Text Available In this article we investigate the possibility of scaling down enzyme-gelatin modified electrodes by spin coating the enzyme-gelatin layer. Special attention is given to the electrochemical behavior of the selected enzymes inside the gelatin matrix. A glassy carbon electrode was used as a substrate to immobilize, in the first instance, horse heart cytochrome c (HHC in a gelatin matrix. Both a drop dried and a spin coated layer was prepared. On scaling down, a transition from diffusion controlled reactions towards adsorption controlled reactions is observed. Compared to a drop dried electrode, a spin coated electrode showed a more stable electrochemical behavior. Next to HHC, we also incorporated catalase in a spin coated gelatin matrix immobilized on a glassy carbon electrode. By spincoating, highly uniform sub micrometer layers of biocompatible matrices can be constructed. A full electrochemical study and characterization of the modified surfaces has been carried out. It was clear that in the case of catalase, gluteraldehyde addition was needed to prevent leaking of the catalase from the gelatin matrix.

    Multiphoton effects in down-conversion are investigated based on the full-quantum multimode formalism by considering a three-level system as a prototype nonlinear system. We analytically derive the three-photon output wave function for two input photons, where one of the two input photons is down-converted and the other one is not. Using this output wave function, we calculate the down-conversion probability, the purity, and the fidelity to evaluate the entanglement between a down-converted photon pair and a non-down-converted photon. It is shown that the saturation effect occurs by multiphoton input and that it affects both the down-conversion probability and the quantum correlation between the down-converted photon pair and the non-down-converted photon. We also reveal the necessary conditions for multiphoton effects to be strong.

    Full Text Available As a universal human phenomenon, religion is rooted in human nature, and human beings instinctively require a superior and supreme power. Besides this internal need for religion, attention to the meaning, function, and interpretation of religion has always been prevalent in the history of human thought from West to East, and scholars have always tried to comment on and analyze this fundamental issue of human life .  From among the approaches that arose about the interpretation and explanation of religion, rationalism tendency—influenced by evolution—has stood up because in the establishment of religion, rationalism takes its genesis and evolution as manifestations of the evolution of human thought, and it takes the development and evolution of religion as equal. This approach considers religion as answer to the need of the cognitive need of human beings. In this anthropological approach, religion is the product of primitive human beings’ effort to identify objects and events in the surrounding environment. As a results, as the man’s knowledge of the world around him increases, the need for religion decreases .  Anthropologist like Edward Tylor and James Frazer have taken this view to the origin and evolution of religion. They emphasize on principles such as the bodily and cognitive unity of the mind, the survival principal, and the evolutionary intellectual pattern of human beings in order to interpret religion stages from animism and magic till monism and monotheism, which will eventually decline during the development of science .  Taylor regards anthropology as the best scientific method to achieve a universal theory to understand the origin of religion. Based on its psychological unity, religion in all times and places—despite its diversity—is a unique phenomenon and has an exclusive identity because the very existence of commonalities in all practices and customs of the people of the world is indicative of the basic

Besides this internal need for religion, attention to the meaning, function, and interpretation of religion has always been prevalent in the history of human thought from West to East, and scholars have always tried to comment on and analyze this fundamental issue of human life .  From among the approaches that arose about the interpretation and explanation of religion, rationalism tendency—influenced by evolution—has stood up because in the establishment of religion, rationalism takes its genesis and evolution as manifestations of the evolution of human thought, and it takes the development and evolution of religion as equal. This approach considers religion as answer to the need of the cognitive need of human beings. In this anthropological approach, religion is the product of primitive human beings’ effort to identify objects and events in the surrounding environment. As a results, as the man’s knowledge of the world around him increases, the need for religion decreases .  Anthropologist like Edward Tylor and James Frazer have taken this view to the origin and evolution of religion. They emphasize on principles such as the bodily and cognitive unity of the mind, the survival principal, and the evolutionary intellectual pattern of human beings in order to interpret religion stages from animism and magic till monism and monotheism, which will eventually decline during the development of science .  Taylor regards anthropology as the best scientific method to achieve a universal theory to understand the origin of religion. Based on its psychological unity, religion in all times and places—despite its diversity—is a unique phenomenon and has an exclusive identity because the very existence of commonalities in all practices and customs of the people of the world is indicative of the basic

    A new genus, Nubensia Spies, is proposed for N. nubens (Edwards, 1929), n. comb., based on morphological evaluation of both adult sexes, the pupa and larva. The material studied includes name-bearing syntype specimens and the first reared associations linking three life stages for individual members of this species. The larva represents a unique morphotype previously described incompletely only from studies of subfossil chironomid remains. The problems with placement of the species in any previously established genus are discussed in detail, and various related issues in taxonomy and nomenclature are commented on. The verified distribution of N. nubens ranges from the British Isles and central Europe to the western Mediterranean, including northern Africa, with possible extensions to Turkey and central Asia. Larvae have been found on mostly coarse, variously covered substrates near the shores of lakes and banks of slowly flowing running waters, under both oligotrophic and eutrophic conditions.

    Many researchers have studied the downdip limit of freshwater in the Edwards aquifer or various aspects of the saline-water zone and its relation to the freshwater zone. These studies were summarized and used to synthesize a consistent hydrologic and geochemical framework from which to interpret data from field studies. The concept derived from the previous work on the downdip limit of the freshwater zone is that fresh recharge water entered the aquifer and developed a vast flow system controlled by barrier faults. Some recharge water flows into the saline-water zone rather than toward major freshwater discharge points. The water that enters the salinewater zone continues to dissolve gypsum and dolomite, and calcite precipitates out of the water. This process of dedolomitization has helped to develop the large secondary porosity of the freshwater zone as the downdip limit of the freshwater zone progressively moved downdip in recent geologic time.

    We investigated numerical estimation in children with Down syndrome (DS) in order to assess whether their pattern of performance is tied to experience (age), overall cognitive level, or specifically impaired. Siegler and Opfer's (2003) number to position task, which requires translating a number into a spatial position on a number line, was administered to a group of 21 children with DS and to two control groups of typically developing children (TD), matched for mental and chronological age. Results suggest that numerical estimation and the developmental transition between logarithm and linear patterns of estimates in children with DS is more similar to that of children with the same mental age than to children with the same chronological age. Moreover linearity was related to the cognitive level in DS while in TD children it was related to the experience level. Copyright © 2014. Published by Elsevier Ltd.

  13. Strategic Style in Pared-Down Poker

    Science.gov (United States)

    Burns, Kevin

    This chapter deals with the manner of making diagnoses and decisions, called strategic style, in a gambling game called Pared-down Poker. The approach treats style as a mental mode in which choices are constrained by expected utilities. The focus is on two classes of utility, i.e., money and effort, and how cognitive styles compare to normative strategies in optimizing these utilities. The insights are applied to real-world concerns like managing the war against terror networks and assessing the risks of system failures. After "Introducing the Interactions" involved in playing poker, the contents are arranged in four sections, as follows. "Underpinnings of Utility" outlines four classes of utility and highlights the differences between them: economic utility (money), ergonomic utility (effort), informatic utility (knowledge), and aesthetic utility (pleasure). "Inference and Investment" dissects the cognitive challenges of playing poker and relates them to real-world situations of business and war, where the key tasks are inference (of cards in poker, or strength in war) and investment (of chips in poker, or force in war) to maximize expected utility. "Strategies and Styles" presents normative (optimal) approaches to inference and investment, and compares them to cognitive heuristics by which people play poker--focusing on Bayesian methods and how they differ from human styles. The normative strategy is then pitted against cognitive styles in head-to-head tournaments, and tournaments are also held between different styles. The results show that style is ergonomically efficient and economically effective, i.e., style is smart. "Applying the Analysis" explores how style spaces, of the sort used to model individual behavior in Pared-down Poker, might also be applied to real-world problems where organizations evolve in terror networks and accidents arise from system failures.

  14. Distribution of sulphur isotopes of sulphates in groundwaters from the principal artesian aquifer of Florida and the Edwards aquifer of Texas, United States of America

    New information on the sources of sulphate dissolved in groundwater is obtainable from the measurement of the sulphur isotope composition of sulphates. Field studies in the Floridan aquifer, Florida, and the Edwards aquifer, Texas, show that the use of sulphur isotope data in conjunction with hydrologic and geochemical techniques permits refinements of interpretation. In the Floridan the interpretation of the chemical data, particularly the SO 4 2- concentration and the SO 4 2- /Cl - ratio, leads to the conclusion that recharging maritime rainfall, solution of intraformational gypsum, and mixing with ocean-like saline waters are the sources of sulphate in the groundwater. Sulphur isotope data substantiate this interpretation. The Edwards in the area studied can be separated into two hydrologie units on the basis of water chemistry and aquifer characteristics. The sulphide-free waters in the part of the aquifer upgradient from a distinct sulphide boundary are low in sulphate (less than 100 mg/1) and contain no sulphide. The waters downgradient from that boundary contain greater than 150 mg/1 sulphate and all contain measurable quantities of sulphide. Interpretation of the SO 4 2- concentration and SO 4 2- /Cl ratio on the basis of the Florida study leads to the erroneous conclusion that the solution of intraformational gypsum is again a major source of sulphate in the sulphide-free part of the aquifer. Isotope analyses, however, show that the gypsum is likely to be Permian in age and introduced into the aquifer by the recharge water. The absence of evidence for enrichment in 34 S in the sulphate in the sulphide-bearing portion of the aquifer leads to the possibility of H 2 S migration upgradient from downdip oil fields. (author)

    Ground based remote sensing is a novel technique for development of digital outcrop models which can be instrumental in performing detailed qualitative and quantitative sedimentological analysis for the study of depositional environment, diagenetic processes, and hydrocarbon reservoir characterization. For this investigation, ground-based hyperspectral data collection is combined with terrestrial LiDAR to study outcrops of Late Albian rudist buildups of the Edwards formation in the Lake Georgetown Spillway in Williamson County, Texas. The Edwards formation consists of shallow water deposits of reef and associated inter-reef facies, including rudist bioherms and biostromes. It is a significant aquifer and was investigated as a hydrocarbon play in south central Texas. Hyperspectral data were used to map compositional variation in the outcrop by distinguishing spectral properties unique to each material. Lithological variation was mapped in detail to investigate the structure and composition of rudist buildups. Hyperspectral imagery was registered to a 3D model produced from the LiDAR point cloud with an accuracy of up to one pixel. Flat-topped toucasid-rich bioherm facies were distinguished from overlying toucasid-rich biostrome facies containing chert nodules, overlying sucrosic dolostones, and uppermost peloid wackestones and packstones of back-reef facies. Ground truth was established by petrographic study of samples from this area and has validated classification products of remote sensing data. Several types of porosity were observed and have been associated with increased dolomitization. This ongoing research involves integration of remotely sensed datasets to analyze geometrical and compositional properties of this carbonate formation at a finer scale than traditional methods have achieved and seeks to develop a workflow for quick and efficient ground based remote sensing-assisted outcrop studies.

  16. The up and down of sleep: From molecules to electrophysiology.

    2018-03-12

    Alternations of up and down can be seen across many different levels during sleep. Neural firing-rates, synaptic markers, molecular pathways, and gene expression all show differential up and down regulation across brain areas and sleep stages. And also the hallmarks of sleep - sleep stage specific oscillations - are characterized themselves by up and down as seen within the slow oscillation or theta cycles. In this review, we summarize the up and down of sleep covering molecules to electrophysiology and present different theories how this up and down could be regulated by the up and down of sleep oscillations. Further, we propose a tentative theory how this differential up and down could contribute to various outcomes of sleep related memory consolidation: enhancement of hippocampal representations of very novel memories and cortical consolidation of memories congruent with previous knowledge-networks.

  17. Can we afford shutting down power stations?

    Hesse, David

    2015-01-01

    The author discusses and criticizes some popular beliefs on the profitability of nuclear power stations, on the fact that they are now too old to be exploited, and on the fact that nuclear energy is the most subsidised energy. As some European countries decided to phase out nuclear, he notices that the decrease of gas prices undermines the profitability of nuclear power stations in the USA and that new rules aimed at the reduction of CO 2 emissions result in high subsidies for renewable energies which are however handicapped by the grid ability to integrate all energies. He outlines that shutting down a nuclear power station costs a lot of money to the society, and denies the argument of non-profitability of these stations. He states that the issue of nuclear subsidies is in fact a matter of tax policy. He also states that these so-said old power stations take in fact advantage of numerous technical innovations for their equipment, components, technology and fuels which improve their efficiency, durability, performance and flexibility

    Full Text Available Introduction and Aim. Down syndrome (DS is associated with numerous developmental abnormalities, some of which cause dysfunctions of the posture and the locomotor system. The analysis of selected features of the foot structure in boys with DS versus their peers without developmental disorders is done. Materials and Methods. The podoscopic examination was performed on 30 boys with DS aged 14-15 years. A control group consisted of 30 age- and gender-matched peers without DS. Results. The feet of boys with DS are flatter compared to their healthy peers. The hallux valgus angle is not the most important feature differentiating the shape of the foot in the boys with DS and their healthy peers. In terms of the V toe setting, healthy boys had poorer results. Conclusions. Specialized therapeutic treatment in individuals with DS should involve exercises to increase the muscle strength around the foot joints, enhancing the stabilization in the joints and proprioception. Introducing orthotics and proper footwear is also important. It is also necessary to monitor the state of the foot in order to modify undertaken therapies.

    The debate on business and the environment has typically been framed in simple yes-or-no terms: "Does it pay to be green?" But the environment, like other business issues, requires a more complex approach--one that demands more than such all-or-nothing thinking. Managers need to ask instead, "Under what circumstances do particular kinds of environmental investments deliver returns to shareholders?" This article presents five approaches that managers can take to identify those circumstances and integrate the environment into their business thinking. These approaches will enable companies with the right industry structure, competitive position, and managerial skills to reconcile their responsibility to shareholders with the pressure to be faithful stewards of the earth's resources. Some companies can distance themselves from competitors by differentiating their products and commanding higher prices for them. Others may be able to "manage" their competitors by imposing a set of private regulations or by helping to shape the rules written by government officials. Still others may be able to cut costs and help the environment simultaneously. Almost all can learn to improve their management of risk and thus reduce the outlays associated with accidents, lawsuits, and boycotts. And some companies may even be able to make systemic changes that will redefine competition in their markets. All five approaches can help managers bring the environment down to earth. And that means bringing the environment back into the fold of business problems and determining when it really pays to be green.

  20. Oxidative stress, thyroid dysfunction & Down syndrome

    Directory of Open Access Journals (Sweden)

    2015-01-01

    Full Text Available Down syndrome (DS is one of the most common chromosomal disorders, occurring in one out of 700-1000 live births, and the most common cause of mental retardation. Thyroid dysfunction is the most typical endocrine abnormality in patients with DS. It is well known that thyroid dysfunction is highly prevalent in children and adults with DS and that both hypothyroidism and hyperthyroidism are more common in patients with DS than in the general population. Increasing evidence has shown that DS individuals are under unusual increased oxidative stress, which may be involved in the higher prevalence and severity of a number of pathologies associated with the syndrome, as well as the accelerated ageing observed in these individuals. The gene for Cu/Zn superoxide dismutase (SOD1 is coded on chromosome 21 and it is overexpressed (~50% resulting in an increase of reactive oxygen species (ROS due to overproduction of hydrogen peroxide (H 2 O 2 . ROS leads to oxidative damage of DNA, proteins and lipids, therefore, oxidative stress may play an important role in the pathogenesis of DS.

    The present work is aimed at analysing executive function (EF) in adolescents with Down Syndrome (DS). So far, EF has been analysed mainly in adults with DS, showing a pattern of impairment. However, less is known about children and adolescents with this syndrome. Studying adolescents with DS might help us better understand whether performances on EF tasks of individuals with DS are determined by age or by Alzheimer disease, as some studies suggest, or whether their performances are directly related to DS cognitive profile. A battery of EF tasks assessing set shifting, planning/problem-solving, working memory, inhibition/perseveration and fluency, as well as a tasks assessing sustained attention has been administered to a group of 15 adolescents with DS and 15 typically developing children matched for mental age. All EF tasks were selected from previous studies with individuals with intellectual disabilities or from developmental literature and are thought to be useful for the samples considered. The present results revealed that the group of individuals with DS performed at a significantly lower level on tasks assessing set shifting, planning/problem-solving, working memory and inhibition/perseveration, but not on the tasks assessing fluency. In addition, individuals with DS demonstrated a greater number of errors and less strategy use for the sustained attention task. The results suggest a broad impairment in EF in adolescents with DS, and are consistent with several similar studies conducted with adults with DS. We assume that EF deficit is a characteristic of DS.

    The possible occurrence of dead zones in protoplanetary discs subject to the magneto-rotational instability highlights the importance of disc ionization. We present a closed-form theory for the deep-down ionization by X-rays at depths below the disc surface dominated by far-ultraviolet radiation. Simple analytic solutions are given for the major ion classes, electrons, atomic ions, molecular ions and negatively charged grains. In addition to the formation of molecular ions by X-ray ionization of H2 and their destruction by dissociative recombination, several key processes that operate in this region are included, e.g. charge exchange of molecular ions and neutral atoms and destruction of ions by grains. Over much of the inner disc, the vertical decrease in ionization with depth into the disc is described by simple power laws, which can easily be included in more detailed modelling of magnetized discs. The new ionization theory is used to illustrate the non-ideal magnetohydrodynamic effects of Ohmic, Hall and Ambipolar diffusion for a magnetic model of a T Tauri star disc using the appropriate Elsasser numbers.

    1994-01-01

    Lymphocytes from both Down syndrome (DS) patients and age-matched control donors have been investigated to identify a possible disturbance in chromosomal G2 repair. Analyses of caffeine treatments during G2 have shown that the frequency of chromosomal aberrations is higher in DS lymphocytes than in normal lymphocytes. Likewise, G2 duration is longer in DS cells than in normal cells. In both control and DS lymphocytes, caffeine treatments increase the frequencies of chromatid breakages and decrease the average of G2 duration. The reversal of the caffeine potentiation effect by adenosine and niacinamide is higher in DS cells than in normal cells. Furthermore, ATP content per cell in DS lymphocytes is one third of that estimated in normal lymphocytes. The increase of ATP level produced by adenosine or niacinamide generally correlates with the reversal of the caffeine effect on chromosome aberrations. Under the experimental conditions tested, a good negative exponential correlation between ATP level and chromosome aberrations has been detected in both normal and DS lymphocytes which were or were not X-irradiated. Finally, we postulate a decrease in G2 repair capability of DS lymphocytes caused by a low availability of ATP and/or some other factor correlating with it. (au)

  4. The Ups and Downs of Repeated Cleavage and Internal Fragment Production in Top-Down Proteomics

    Analysis of whole proteins by mass spectrometry, or top-down proteomics, has several advantages over methods relying on proteolysis. For example, proteoforms can be unambiguously identified and examined. However, from a gas-phase ion-chemistry perspective, proteins are enormous molecules that present novel challenges relative to peptide analysis. Herein, the statistics of cleaving the peptide backbone multiple times are examined to evaluate the inherent propensity for generating internal versus terminal ions. The raw statistics reveal an inherent bias favoring production of terminal ions, which holds true regardless of protein size. Importantly, even if the full suite of internal ions is generated by statistical dissociation, terminal ions are predicted to account for at least 50% of the total ion current, regardless of protein size, if there are three backbone dissociations or fewer. Top-down analysis should therefore be a viable approach for examining proteins of significant size. Comparison of the purely statistical analysis with actual top-down data derived from ultraviolet photodissociation (UVPD) and higher-energy collisional dissociation (HCD) reveals that terminal ions account for much of the total ion current in both experiments. Terminal ion production is more favored in UVPD relative to HCD, which is likely due to differences in the mechanisms controlling fragmentation. Importantly, internal ions are not found to dominate from either the theoretical or experimental point of view. [Figure not available: see fulltext.

    Previous studies have shown that over 40% of babies with Down syndrome have a major cardiac anomaly and are more likely to have other major congenital anomalies. Since 2000, many countries in Europe have introduced national antenatal screening programs for Down syndrome. This study aimed...... to determine if the introduction of these screening programs and the subsequent termination of prenatally detected pregnancies were associated with any decline in the prevalence of additional anomalies in babies born with Down syndrome. The study sample consisted of 7,044 live births and fetal deaths with Down...... syndrome registered in 28 European population-based congenital anomaly registries covering seven million births during 2000-2010. Overall, 43.6% (95% CI: 42.4-44.7%) of births with Down syndrome had a cardiac anomaly and 15.0% (14.2-15.8%) had a non-cardiac anomaly. Female babies with Down syndrome were...

    2012-03-01

    The American Journal of Medical Genetics Part A is to be congratulated for taking a leadership role by publishing a number of papers challenging the status quo of prenatal counseling for Down syndrome and of care for children and adults with Down syndrome. Parents want to know about the future abilities and potential of their fetus with Down syndrome, not simply negative medical information that may be outdated. Those providing counseling and those providing medical care could benefit from contact with individuals with Down syndrome outside the medical context. It is imperative that each person with Down syndrome be viewed as a unique individual with particular talents. Medical care providers should work with parents to help the child or adult with Down syndrome reach his/her goals. Copyright © 2012 Wiley Periodicals, Inc.

    Full Text Available Introduction: There are few studies that investigated whether Down syndrome (DS interferes with references values for complete blood counts (CBC test in children with the syndrome. Objective: This study aimed to analyze the results of CBC performed in children with DS. Patients and methods: Data from CBC of DS children were included; at the time of examination they were aged between 2 and 10 years and had no clinical signs and/or symptoms of infectious disease. The hematological parameters analyzed were: total number of erythrocytes (RBC, hemoglobin (Hb concentration, hematological indices, platelet count, and total number of leucocytes. Additionally, we compared the collected parameters according to gender and age of the children studied. Results: A total of 203 CBC (100 girls and 103 boys were evaluated. In general, no significant differences were observed in studied parameters between the values found in samples of DS children and the values described in the literature as a reference for children in this age group. No difference in the prevalence of anemia was observed in relation to gender (p = 0.33, 14/103 (13.6% boys, and 11/100 (11% girls had anemia. However, the Hb and hematological indices values found in boys was significantly lower than in girls (p < 0.001. Conclusion: This investigation is the first one in Brazil to present and analyze the CBC results of DS children, reporting that their hematological indices are within the expected range for children without DS. Additionally, it was found that 12.3% of them had anemia.

  8. Speech impairment in Down syndrome: a review.

    Kent, Ray D; Vorperian, Houri K

    2013-02-01

    This review summarizes research on disorders of speech production in Down syndrome (DS) for the purposes of informing clinical services and guiding future research. Review of the literature was based on searches using MEDLINE, Google Scholar, PsycINFO, and HighWire Press, as well as consideration of reference lists in retrieved documents (including online sources). Search terms emphasized functions related to voice, articulation, phonology, prosody, fluency, and intelligibility. The following conclusions pertain to four major areas of review: voice, speech sounds, fluency and prosody, and intelligibility. The first major area is voice. Although a number of studies have reported on vocal abnormalities in DS, major questions remain about the nature and frequency of the phonatory disorder. Results of perceptual and acoustic studies have been mixed, making it difficult to draw firm conclusions or even to identify sensitive measures for future study. The second major area is speech sounds. Articulatory and phonological studies show that speech patterns in DS are a combination of delayed development and errors not seen in typical development. Delayed (i.e., developmental) and disordered (i.e., nondevelopmental) patterns are evident by the age of about 3 years, although DS-related abnormalities possibly appear earlier, even in infant babbling. The third major area is fluency and prosody. Stuttering and/or cluttering occur in DS at rates of 10%-45%, compared with about 1% in the general population. Research also points to significant disturbances in prosody. The fourth major area is intelligibility. Studies consistently show marked limitations in this area, but only recently has the research gone beyond simple rating scales.

    Old living oaks (Quercus robur) are known as a very species-rich habitat for saproxylic beetles, but it is less clear to what extent such veteran trees differ from an even rarer feature: downed trunks of large oaks. In this study, we set out to sample this habitat, using window traps, with two aims: (1) to describe the variation of assemblages among downed trunks of different type and (2) to compare beetles on downed oaks with data from veteran standing trees. The results showed that trunk volume and sun exposure better explained assemblages as well as species numbers on downed trunks than did decay stage. Furthermore, species classified as facultative saproxylic species showed weak or no differentiation among downed trunks. Species with different feeding habits showed no apparent differentiation among downed trunks. Furthermore, species composition on dead, downed oak trunks differed sharply from that of living, veteran oaks. Wood or bark feeders were more common on veterans than downed trunks, but there was no difference for those species feeding on fungi or those feeding on insects and their remains. In conclusion, for a successful conservation of the saproxylic beetle fauna it is important to keep downed oak trunks, and particularly large ones, in forest and pastures as they constitute a saproxylic habitat that differs from that of living trees.

    2008-10-01

    Children with Down syndrome experience significant communication impairments, particularly in expressive language. Although receiving little attention in the literature, deficiencies in expressive language are likely to affect spontaneous communicative responses in children with Down syndrome. In this study, using a multiple baseline design across responses, we demonstrated the effectiveness of discrete trial instruction in establishing spontaneous responses in a preschooler with Down syndrome. Spontaneous responses generalised to a novel setting involving a novel person and novel materials. Implications for the use of behaviourally based interventions to address the social-communicative needs of children with Down syndrome are discussed.

  13. EASTERN MYSTICISM AND TIMOTHY LEARY: HUMAN BEYOND THE CONVENTIONAL REALITY

    Directory of Open Access Journals (Sweden)

    T. V. Danylova

    2017-06-01

    Full Text Available Introduction. The complex multifaceted essence of human as a biological, psychological, social being has attracted the attention of researchers and has caused hot debates during centuries. Still now, human being, her/his nature requires a broader understanding in the context of the synthesis of long-standing philosophical, psychological, religious traditions and contemporary sciences. Purpose. This paper aims to explore the phenomenon of human being through the lens of the Eastern philosophy and T. Leary’s transpersonal perspective. Methodology. Exploratory research design was used for conducting this study. The author has used philosophical hermeneutics, secondary data collected from reports, journals, and periodicals along with own transpersonal experience. Theoretical basis and results. The essence of Eastern worldview is an awareness of unity and coherence of all things and phenomena. All things are the interdependent and interrelated parts of the One Whole: they are the different manifestations of the same unconditional reality. This is Tao for Taoists, Dharmakaya for Buddhists, Brahman for Hindus. These non-dualistic traditions emphasize: we have to transcend our dual thinking in order to perceive true nature of our inner self and to achieve the state of the absolute unity with everything that exists. “Subject – object” duality is illusory. Being disintegrated from the Oneness, a human is dissociated into different parts. The goal of a new interpretation of a human is to reintegrate these poles and transcend them. Merely theoretical approach to the problem of reintegration is insufficient. Reintegration requires a vivid experience of the “liberation” – the experience of enlightenment. This is a transpersonal experience that overcomes our common perception and goes beyond the usual “body-mind” frame. This experience was breathtakingly described by T. Leary. Experimenting with psilocybin and LSD, T. Leary was astonished that creativity was organically based; that human body contained billions of universes; and that human himself was the movement of various forms of energy. T. Leary proposed his own theory of evolution. Originality. The expansion of human horizons leads us to the new understanding/interpretation of a human being. Bringing the Eastern spiritual traditions, which perceive all objects and phenomena as various interrelated aspects of a single supreme reality, transpersonal psychology and modern sciences together, contemporary philosophers are able to design and develop a new approach to a human that will bridge the gap between different interpretations of a human being. T. Leary’s ideas resonate with both quantum physics and the Eastern philosophy. In the 21st century, T. Leary’s ideas are relevant again. Conclusion. The Eastern spiritual teachings and transpersonal experience put the human problem in a completely different context. It induces us to switch from identifying human beings with the body, mind, ego to embracing them as whole organisms interwoven into the fabric of universal entity. This holistic approach, according to which a human is an undivided, alive and organic, ideal and material being, may be seen as a launching pad for a new transdisciplinary paradigm.

    At the age of 46, Dr Edward Macgowan, by now a well-established physician, joined the ranks of the London Society for Promoting Christianity among the Jews with the aim of establishing the first modern hospital in Palestine. For the first six months of 1842, Macgowan established his work among the Jerusalem population on a regular basis and managed to establish a close relationship with the Jewish community and some of its leaders in Jerusalem. On 12 December 1844, the Jews' Hospital was opened in Jerusalem and became a source of great pride for the missionaries. Edward Macgowan died in Jerusalem after 18 years of service and was buried in the Protestant cemetery in his beloved city.

    A review of the literature addressing sediment transport in gravel-bed river systems and structures designed to control bed-load mobility is provided as part of Texas Department of Transportation research project 0–4695: Guidance for Design in Areas of Extreme Bed-Load Mobility. The study area comprises the western half of the Edwards Plateau in central Texas. Three primary foci of the literature review are journal articles, edited volumes, and government publications. Major themes within the body of literature include deterministic sediment transport theory and equations, development of methods to measure and analyze fluvial sediment, applications and development of theory in natural channels and flume experiments, and recommendations for river management and structural design. The literature review provides an outline and foundation for the research project to characterize extreme bed-load mobility in rivers and streams across the study area. The literature review also provides a basis upon which potential modifications to low-water stream-crossing design in the study area can be made.

  18. Modeling effects of nitrate from non-point sources on groundwater quality in an agricultural watershed in Prince Edward Island, Canada

    Science.gov (United States)

    Jiang, Yefang; Somers, George

    2009-05-01

    Intensification of potato farming has contaminated groundwater with nitrate in many cases in Prince Edward Island, Canada, which raises concerns for drinking water quality and associated ecosystem protection. Numerical models were developed to simulate nitrate-N transport in groundwater and enhance understanding of the impacts of farming on water quality in the Wilmot River watershed. Nitrate is assumed non-reactive based on δ15N and δ18O in nitrate and geochemical information. The source functions were reconstructed from tile drain measurements, N budget and historical land-use information. The transport model was calibrated to long-term nitrate-N observations in the Wilmot River and verified against nitrate-N measurements in two rivers from watersheds with similar physical conditions. Simulations show groundwater flow is stratified and vertical flux decreases exponentially with depth. While it would take several years to reduce the nitrate-N in the shallow portion of the aquifer, it would take several decades or even longer to restore water quality in the deeper portions of the aquifer. Elevated nitrate-N concentrations in base flow are positively correlated with potato cropping intensity and significant reductions in nitrate-N loading are required if the nitrate level of surface water is to recover to the standard in the Canadian Water Quality Guidelines.

  19. Effects of projected climate (2011–50) on karst hydrology and species vulnerability—Edwards aquifer, south-central Texas, and Madison aquifer, western South Dakota

    Karst aquifers—formed by the dissolution of soluble rocks such as limestone—are critical groundwater resources in North America, and karst springs, caves, and streams provide habitat for unique flora and fauna. Springflow and groundwater levels in karst terrane can change greatly over short time scales, and therefore are likely to respond rapidly to climate change. How might the biological communities and ecosystems associated with karst respond to climate change and accompanying changes in groundwater levels and springflow? Sites in two central U.S. regions—the Balcones Escarpment of south-central Texas and the Black Hills of western South Dakota (fig. 1)—were selected to study climate change and its potential effects on the local karst hydrology and ecosystem. The ecosystems associated with the Edwards aquifer (Balcones Escarpment region) and Madison aquifer (Black Hills region) support federally listed endangered and threatened species and numerous State-listed species of concern, including amphibians, birds, insects, and plants. Full results are provided in Stamm and others (2014), and are summarized in this fact sheet.

    Full Text Available O conceito de linguagem perpassa diferentes abordagens teóricas e diferentes cientistas sem ser, no entanto, consensual na Linguística. Todavia, algumas características similares acerca do fenômeno da linguagem são encontradas nas abordagens de Edward Sapir e Mattoso Câmara Jr., principalmente, por este último ter realizado traduções de duas obras de Sapir e ter convivido diretamente com grandes linguistas estruturalistas, nos Estados Unidos. O presente artigo descreve e discute algumas das principais aproximações entre as ideias de Mattoso Câmara Jr. e Sapir, que sugerem a filiação do primeiro ao segundo. A partir disso, buscaram-se os aspectos de convergência das concepções linguísticas e identificaram-se três, relacionados à (i linguagem e pensamento, (ii linguagem e arte e (iii linguagem e deriva linguística.
