Born in Geneva on 27 April 1921, Louis obtained a physics degree at ETH-Zurich in 1946 before moving to the Institut du Radium in Paris, where he joined the group led by Frédéric and Irène Joliot-Curie. He took a leave of absence in 1957 to go to CERN, where he remained until well beyond his retirement in 1986. In the late 1950s and early 1960s, Louis worked at CERN’s Synchrocyclotron (SC) and later on studies at the Proton Synchrotron (PS). When the first polarised proton target arrived at CERN from Saclay in 1963, Louis proposed using it for studies of spin effects in pion-proton elastic scattering at the PS, and between 1964 and 1966 sizeable spin effects were found. Louis and his collaborators then continued these studies wi...

    Toledo-Pereyra, Luis H

    2009-01-01

    Louis Pasteur (1822-1895) is considered the most notable medical scientist of his time and perhaps one of the most distinguished of all times in the history of medicine. From Dole in France to Paris, from a student of crystals to "living ferments," and from chemistry to biology and medicine, Pasteur changed the world for the benefit of humanity. The genius of Pasteur dealt with the most pressing issues of his time, basing the germ theory on the effects that microorganisms had on fermentation and putrefaction of organic matter, which gave birth to the science of bacteriology. Many other difficult problems in medicine and biology were tackled by Pasteur, culminating in the spectacular results seen with the treatment of rabies. Surgery was no exception to the scientific conquests of Pasteur. The transformation of the surgical world arose from the antiseptic concepts of Lister that were based on the germ theory of the disease, which had been derived from the germ theory of fermentation and putrefaction discovered by Pasteur. The acceptance of these principles represented the surgical revolution brought on by the science of Pasteur, a revolution that is now accepted in our daily care of surgical patients.

  11. Public health assessment for St. Louis Airport, Hazelwood Interim Storage/Futura Coatings Company, St. Louis, St. Louis County, Missouri, Region 7. Cerclis No. MOD980633176. Preliminary report

    Energy Technology Data Exchange (ETDEWEB)

    1994-01-20

    The St. Louis Airport/Hazelwood Iterim Storage/Futura Coatings Company, a National Priorities List site, is in St. Louis County, Missouri. From 1946 to 1973, the site was used to store radioactive materials resulting from uranium processing. High levels of uranium, thorium, radium, and radon were detected in soil, groundwater, and air. The site is still being used to store radioactive materials. The Agency for Toxic Substances and Disease Registry considers the St. Louis Airport site to be an indeterminate public health hazard. Although there are emissions of radon and the presence of thorium in on-site air and off-site soils and the emission of radiation resulting from the presence of these materials is not currently considered a health hazard. At present conditions, the concentration of radon off-site is indistinguishable from background levels. However, in the past, these contaminants may have been present at levels of health concern.

    Although by the mid-nineteenth century evidence existed for an association between micoorganisms and disease, it was the combined efforts of Louis Pasteur and Robert Koch that created the germ theory of disease--the theory that specific microbes cause specific diseases. Surprisingly, the relationship between the two founders of microbiology and immunology was far from friendly.

  13. Professor Louis Michel (1923-1999)

    Professor Louis Michel was born on May 4, 1923 in Roanne, France and died of aneurysm on December 30, 1999 in Bures-Sur-Yvette, France. With the untimely and sudden death of Louis Michel the world physics community has lost one of its most prominent members. The extraordinary popularity and respect to Louis as a scientist and a man was demonstrated in his funeral ceremony at l'Eglise de Bures-Sur-Yvette when many people from all over the world came to part from him. Many obituaries appeared in Louis' memory in different journals and among them Physics Today, Cern Courier, Physics Reports, in the Bulletin of the French Embassy in Israel and others. It is certainly impossible in this short lecture to give an adequate description of Prof. Michel's contributions in physics but if one looks for a way to identify a niche that Louis occupies in science of the 20th century, this can best be done by his relation to Eugene Wigner whom Louis much admired. On July 16, 1996 Prof. Michel gave the Wigner Memorial Lecture at the 21st International Colloquium on Group Theoretical Methods in Physics. 1 This was the first Colloquium after Wigner's death (who died on January 1, 1995). Wigner had a very great influence on Louis which started during Louis' membership at the Institute of Advanced Studies at Princeton in the years 1953-55. For Louis Wigner was (in Louis' words) a "model in science: a complete physicist, drawing, when necessary, from his deep mathematical culture". In my view, on the world arena of science, Prof. Michel was one of Wigner's successors in the field of symmetries in physics, and many of us would agree that the above quotation applies equally well to Louis himself. In his famous book "Group Theory" Wigner thanks in the Preface 4 people, with one of them being Louis Michel, and I quote: "The author also wishes to thank his colleagues for many stimulating discussions on the role of group theory in quantum mechanics as well as on more specific subjects. He wishes

  18. Baseline risk assessment for exposure to contaminants at the St. Louis Site, St. Louis, Missouri

    International Nuclear Information System (INIS)

    The St. Louis Site comprises three noncontiguous areas in and near St. Louis, Missouri: the St. Louis Downtown Site (SLDS), the St. Louis Airport Storage Site (SLAPS), and the Latty Avenue Properties. The main site of the Latty Avenue Properties includes the Hazelwood Interim Storage Site (HISS) and the Futura Coatings property, which are located at 9200 Latty Avenue. Contamination at the St. Louis Site is the result of uranium processing and disposal activities that took place from the 1940s through the 1970s. Uranium processing took place at the SLDS from 1942 through 1957. From the 1940s through the 1960s, SLAPS was used as a storage area for residues from the manufacturing operations at SLDS. The materials stored at SLAPS were bought by Continental Mining and Milling Company of Chicago, Illinois, in 1966, and moved to the HISS/Futura Coatings property at 9200 Latty Avenue. Vicinity properties became contaminated as a result of transport and movement of the contaminated material among SLDS, SLAPS, and the 9200 Latty Avenue property. This contamination led to the SLAPS, HISS, and Futura Coatings properties being placed on the National Priorities List (NPL) of the US Environmental Protection Agency (EPA). The US Department of Energy (DOE) is responsible for cleanup activities at the St. Louis Site under its Formerly Utilized Sites Remedial Action Program (FUSRAP). The primary goal of FUSRAP is the elimination of potential hazards to human health and the environment at former Manhattan Engineer District/Atomic Energy Commission (MED/AEC) sites so that, to the extent possible, these properties can be released for use without restrictions. To determine and establish cleanup goals for the St. Louis Site, DOE is currently preparing a remedial investigation/feasibility study-environmental impact statement (RI/FS-EIS). This baseline risk assessment (BRA) is a component of the process; it addresses potential risk to human health and the environment associated wi

    2014-01-01

    Outside the professional circles of topography and applied mathematics, the life and work of André-Louis Cholesky (1875–1918) are still relatively unknown to the scientific community. This new book appreciably widens the exposure of his remarkable personal achievements in topography and mathematics to a much larger international audience.   Cholesky is also interesting to historians because he is a perfect representative of the "scientists engineers" that, since the early 19th century, had issued from the French scientific high schools. Because they had received a high level of mathematical education, they were able to innovate in their practice of engineering. In the case of Cholesky, this resulted in original contributions in artillery, topography, numerical analysis and graphical calculation. In addition, the book places his education and works within the history of several European countries through the 17th to 19th centuries.   The book begins with Cholesky's biography, followed by his family’s hi...

    International Nuclear Information System (INIS)

    The environmental monitoring program, which began in 1984, continued during 1989 at the St. Louis Airport Site (SLAPS) in St. Louis County, Missouri. SLAPS and its vicinity properties, including ditches north and south of the site, were designated for cleanup as part of the Formerly Utilized Sites Remedial Action Program (FUSRAP), a United States Department of Energy (DOE) program to identify and decontaminate or otherwise control sites where residual radioactive material remains from the early years of the nation's atomic energy program. The monitoring program at SLAPS measures radon concentrations in air; external gamma dose rates; and uranium, thorium, and radium concentrations in surface water, groundwater, and sediment. Additionally, several nonradiological parameters are measured in groundwater. To assess the potential effect of SLAPS on public health, the potential radiation dose was estimated for a hypothetical maximally exposed individual.

  9. Louis pasteur, the father of immunology?

    Science.gov (United States)

    Smith, Kendall A

    2012-01-01

    Louis Pasteur is traditionally considered as the progenitor of modern immunology because of his studies in the late nineteenth century that popularized the germ theory of disease, and that introduced the hope that all infectious diseases could be prevented by prophylactic vaccination, as well as also treated by therapeutic vaccination, if applied soon enough after infection. However, Pasteur was working at the dawn of the appreciation of the microbial world, at a time when the notion of such a thing as an immune system did not exist, certainly not as we know it today, more than 130 years later. Accordingly, why was Pasteur such a genius as to discern how the immune system functions to protect us against invasion by the microbial world when no one had even made the distinction between fungi, bacteria, or viruses, and no one had formulated any theories of immunity. A careful reading of Pasteur's presentations to the Academy of Sciences reveals that Pasteur was entirely mistaken as to how immunity occurs, in that he reasoned, as a good microbiologist would, that appropriately attenuated microbes would deplete the host of vital trace nutrients absolutely required for their viability and growth, and not an active response on the part of the host. Even so, he focused attention on immunity, preparing the ground for others who followed. This review chronicles Pasteur's remarkable metamorphosis from organic chemist to microbiologist to immunologist, and from basic science to medicine.

    Physical activity among youth is shaped by the natural and built environment within which they live; however, few studies have focused on assessing playground safety and proximity in detail as part of the built environment for youth physical activity. We analyzed data on 100 publicly accessible playgrounds from Play Across St. Louis, a community-partnered study of the built environment for youth physical activity. Outcomes included overall playground safety, maintenance, and construction scores; distance to nearest playground; and distance to nearest top playground. Independent variables included neighborhood % youth, % black residents, % owner-occupied units, and % vacant units. Playgrounds in the city have varying degrees of safety and proximity. Mean overall playground safety score was 67.0 % (CI = 63.5, 70.4). Neighborhood % youth and % black residents were inversely associated with overall playground safety (p = 0.03 and p safety scores were found in the northern and central areas while all high safety score clusters were found in the southern part of St. Louis. Public playground safety and proximity vary across St. Louis neighborhoods, especially by neighborhood demographics. Disparities in playground safety and proximity reveal an opportunity to develop community-wide interventions focused on playgrounds for youth activity. Further work is needed to examine the association between playground safety, proximity, and use and youth physical activity and weight. PMID:27393083

    Louis Braille (1809-1852) was born in France. At the age of three, he wounded his right eye with a cobbler's tool while playing in his father's workshop. No medical knowledge could save his eyesight at that time. Louis's left eye became inflamed, apparently due to subsequent sympathetic ophthalmia, and he eventually lost the sight in that eye. At the age of five, Louis Braille was completely blind. He is considered to be the inventor of a writing system by touch that bears his name, the Braille system. This revolutionary system has allowed blind people to access written culture, and it can therefore be considered a major advance in the quality of life for the blind. The immediate precursor of the invention of the Braille system was the alphabet created by Charles Barbier de la Serre (1767-1841) who created a language by touch designed for military and secret use. Louis Braille modified this alphabet into the Braille alphabet, which is practically the same one that is currently used. It required time to be recognized and to be implemented as a reading and writing method for blind people throughout the world. In 1950, UNESCO effectively universalized the Braille alphabet, and in 2005 it recognized Braille system as a "vital language of communication, as legitimate as all other languages in the world."

    2006-12-01

    John Perdrix, astronomical historian and co-founder of the Journal of Astronomical History and Heritage, died on 27 June 2005. John Louis Perdrix was born in Adelaide, Australia, on 30 June 1926. After studying chemistry at Melbourne Technical College and working in industry, he joined the Commonwealth Scientific and Industrial Research Organisation's Division of Minerals and Geochemistry. In 1974 the Division relocated to the Western Australian capital, Perth, and John spent the rest of his working life there involved in geochemical research. From his teenage years John had a passion for astronomy, which he fine-tuned through the Astronomical Society of Victoria and the Victorian Branch of the British Astronomical Association. He was very active in both groups, serving as President of the former and Secretary/Treasurer of the latter. He was also an FRAS, and a member of the AAS, the BAA parent body, and the IAU (Commission 41)?no mean feat for an Australian amateur astronomer. Throughout his life, he was a strong advocate of close amateur-professional relations. John's main research interest was history of astronomy, and over the years he wrote a succession of research papers, mainly about aspects of Australian astronomy. His well-researched and neatly-illustrated papers on the Melbourne Observatory and the Great Melbourne Telescope are classics, and when the Observatory's future was in the balance they played a key role in the State Government's decision to convert this unique facility into a museum precinct. To support his research activities, John built up an amazing library that developed its own distinctive personality and quickly took over his house and garage before invading commercial storage facilities! Apart from writing papers, John had an even greater passion for editing and publishing. From 1985 to 1997 he produced the Australian Journal of Astronomy, and in 1998 this was replaced by the Journal of Astronomical History and Heritage (JAH2). Both

    Louis Pasteur is often regarded as one of the founders of microbiology, and is chiefly famous for his discovery of the role that microorganisms play in health and disease. However, he was trained as a physical scientist, and his research began with the discovery of the stereoisomerism of the different forms of tartaric acid. As a biotechnologist, he is remembered for his studies on the nature of fermentation, and for his rebuttal of the theory of spontaneous generation.

  7. Balzac's Louis Lambert : schizophrenia before Kraepelin and Bleuler.

    Science.gov (United States)

    Dieguez, Sebastian

    2013-01-01

    Honoré de Balzac (1799-1850) is well known for his penetrating observations and descriptions of the burgeoning social life and emerging modernity of 19th century France. This chapter focuses on the novel Louis Lambert, first published in 1832. It is argued that its main character provides the first complete and convincing description of schizophrenia - 69 years before Kraepelin fully developed the concept of dementia praecox and 76 years before Bleuler coined the word 'schizophrenia'. We consider the history of the concept of schizophrenia and the intriguing possibility that it is a recent disease. Indeed, if schizophrenia had always existed, it would seem odd that Balzac's novel should be the very first convincing and complete literary account of the disease. This claim is examined by a thorough description of Louis Lambert's symptoms as they appear in the text, and compared to other claims of priority (namely, Shakespeare's King Lear and Gogol's Diary of a Madman). The chapter also provides some background on Balzac's relationship with mysticism, mental illness, and the world of psychiatry. We conclude with remarks regarding influences of Louis Lambert, the case for the priority of the novel as the princeps case of schizophrenia, and its relevance to the recency hypothesis of schizophrenia.

  16. Introduction to Louis Michel's lattice geometry through group action

    CERN Document Server

    Zhilinskii, Boris

    2015-01-01

    Group action analysis developed and applied mainly by Louis Michel to the study of N-dimensional periodic lattices is the central subject of the book. Different basic mathematical tools currently used for the description of lattice geometry are introduced and illustrated through applications to crystal structures in two- and three-dimensional space, to abstract multi-dimensional lattices and to lattices associated with integrable dynamical systems. Starting from general Delone sets the authors turn to different symmetry and topological classifications including explicit construction of orbifolds for two- and three-dimensional point and space groups. Voronoï and Delone cells together with positive quadratic forms and lattice description by root systems are introduced to demonstrate alternative approaches to lattice geometry study. Zonotopes and zonohedral families of 2-, 3-, 4-, 5-dimensional lattices are explicitly visualized using graph theory approach. Along with crystallographic applications, qualitative ...

    Todorov, Ivan; Zhilinskii, Boris

    2014-01-01

    Reflecting the oeuvre of “a man of two cultures: the culture of pure mathematics and the culture of theoretical physics” (in the words of his long time friend and co-author, Kameshwar Wali), this volume is centred around the notion of symmetry and its breaking. Starting with particle physics, the content proceeds to symmetries of matter, defects, and crystals. The mathematics of group extensions, non-linear group action, critical orbits and phase transitions is developed along the way. The symmetry principles and general mathematical tools provide unity in the treatment of different topics. The papers and lecture notes are preceded by a lively biography of Louis Michel and a commentary that relates his selected works both to the physics of his time and to contemporary trends. This book should be of interest to theoretical physicists, chemists, applied mathematicians and historians of science, and is accessible to graduate (and advanced undergraduate) students.

  18. Louis Pasteur, from crystals of life to vaccination.

    2012-10-01

    Louis Pasteur (1822-1895) is an exceptional scientist who opened a new era in medicine and biology. Starting from studies on crystals of by-products of wine fermentation, he first defined a distinct chemistry between dead and living matters. He then showed the role of living microbes in the fermentation and putrefaction processes. This brought him to challenge the two-millennium-old theory of spontaneous generation, using remarkably well-designed experiments. His observations on epidemics in silkworms allowed him to demonstrate the role of specific germs in infectious diseases. His discovery of the vaccine against fowl cholera can be considered as the birth of immunology. Finally, he became universally recognized through his famous vaccinations against anthrax and rabies.

    Louis Braille was born on January 4th 1809 in Coupvray, France. An injury to his eye at the age of three, resulted in total loss of vision. In 1819 he entered the Institute for Blind Youth in Paris. There he would live, study, and later teach. When he was fifteen, he developed system of reading and writing by means of raised dots, which is known today as Braille. The basis of the Braille system is known as a Braille cell. The cell is comprised of six dots numbered in a specific order. Each dot or combination of dots represents a letter of the alphabet. This Braille system has established itself internationally and formed the basic Braille for all languages.

    Full Text Available The Community Federal Center lies in the outskirts of the town of Saint Louis. It was conceived and designed by the project authors — in a style characteristic of them — as a suburban architectonic complex for office use. The work, standing out over an open stretch of land, has an ample base, with a volume that is neither the actual tower of the city centre nor the classic low rural construction. The building's architectonic language permits an integration, by sympathy, in the context of the neighbouring uni-family housing zone, without naturally being assimilated in them, due to the disparity of functions. It is achieved through a fracture of scaled volumes, breaking the classic coldness of the big office building, whilst at the same time thanks to its robustness, it indicates the activity housed inside.

    Full Text Available IntroductionAbundant evidence shows that regular physical activity (PA is an effective strategy for preventing obesity in people of diverse socioeconomic status (SES and race groups. The proportion of PA performed in parks and how this differs by proximate neighborhood SES has not been thoroughly investigated. The present project analyzes online public web data feeds to assess differences in outdoor PA by neighborhood SES in St. Louis, Missouri, US.MethodsFirst, running and walking routes submitted by users of the website MapMyRun.com were downloaded. The website enables participants to plan, map, record, and share their exercise routes and outdoor activities like runs, walks, and hikes in an online database. Next, the routes were visually illustrated using Geographic Information Systems (GIS. Thereafter, using park data and 2010 Missouri census poverty data, the odds of running and walking routes traversing a low-SES neighborhood, and traversing a park in a low-SES neighborhood were examined in comparison to routes in high-SES neighborhoods and high-SES parks.Results Results show that a majority of running and walking routes occur in, or at least traverse through a park. However, this finding does not hold when comparing low-SES neighborhoods to higher-SES neighborhoods in St. Louis. The odds of running in a park in a low-SES neighborhood were 54 percent lower than running in a park in a higher-SES neighborhood (OR=0.46, CI=0.17-1.23. The odds of walking in a park in a low-SES neighborhood were 17 percent lower than walking in a park in a higher-SES neighborhood (OR = 0.83, CI = 0.26-2.61.ConclusionsThe novel methods of this study include the use of inexpensive, unobtrusive, and publicly available web data feeds to evaluate PA in parks and differences by neighborhood SES. Emerging technologies like MapMyRun.com present significant advantages to enhance tracking of user-defined PA across large geographic and temporal settings.

  6. Presence of selected chemicals of emerging concern in water and bottom sediment from the St. Louis River, St. Louis Bay, and Superior Bay, Minnesota and Wisconsin, 2010

    The St. Louis Bay of Lake Superior receives substantial urban runoff, wastewater treatment plant effluent, and industrial effluent. In 1987, the International Joint Commission designated the St. Louis Bay portion of the lower St. Louis River as one of the Great Lakes Areas of Concern. Concerns exist about the potential effects of chemicals of emerging concern on aquatic biota because many of these chemicals, including endocrine active chemicals, have been shown to affect the endocrine systems of fish. To determine the occurrence of chemicals of emerging concern in the St. Louis River, the St. Louis Bay, and Superior Bay, the U.S. Geological Survey in cooperation with the Minnesota Pollution Control Agency and the Wisconsin Department of Natural Resources collected water and bottom-sediment samples from 40 sites from August through October 2010. The objectives of this study were to (1) identify the extent to which chemicals of emerging concern, including pharmaceuticals, hormones, and other organic chemicals, occur in the St. Louis River, St. Louis Bay, and Superior Bay, and (2) identify the extent to which the chemicals may have accumulated in bottom sediment of the study area. Samples were analyzed for selected wastewater indicators, hormones, sterols, bisphenol A, and human-health pharmaceuticals. During this study, 33 of 89 chemicals of emerging concern were detected among all water samples collected and 56 of 104 chemicals of emerging concern were detected in bottom-sediment samples. The chemical N,N-diethyl-meta-toluamide (DEET) was the most commonly detected chemical in water samples and 2,6-dimethylnaphthalene was the most commonly detected chemical in bottom-sediment samples. In general, chemicals of emerging concern were detected at a higher frequency in bottom-sediment samples than in water samples. Estrone (a steroid hormone) and hexahydrohexamethyl cyclopentabensopyran (a synthetic fragrance) were the most commonly detected endocrine active chemicals in

    The occurrence and sources of Escherichia coli (E. coli), one of several fecal indicator bacteria, in metropolitan St. Louis streams known to receive nonpoint source runoff, occasional discharges from combined and sanitary sewers, and treated wastewater effluent were investigated from October 2004 through September 2007. Three Missouri River sites, five Mississippi River sites, and six small basin tributary stream sites were sampled during base flow and storm events for the presence of E. coli and their sources. E. coli host-source determinations were conducted using local library based genotypic methods. Human fecal contamination in stream samples was additionally confirmed by the presence of Bacteroides thetaiotaomicron, an anaerobic, enteric bacterium with a high occurrence in, and specificity to, humans. Missouri River E. coli densities and loads during base flow were approximately 10 times greater than those in the Mississippi River above its confluence with the Missouri River. Although substantial amounts of E. coli originated from within the study area during base flow and storm events, considerable amounts of E. coli in the Missouri River, as well as in the middle Mississippi River sections downstream from its confluence with the Missouri River, originated in Missouri River reaches upstream from the study area. In lower Mississippi River reaches, bacteria contributions from the numerous combined and sanitary sewer overflows within the study area, as well as contributions from nonpoint source runoff, greatly increased instream E. coli densities. Although other urban factors cannot be discounted, average E. coli densities in streams were strongly correlated with the number of upstream combined and sanitary sewer overflow points, and the percentage of upstream impervious cover. Small basin sites with the greatest number of combined and sanitary sewer overflows (Maline Creek and the River des Peres) had larger E. coli densities, larger loads, and a greater

  8. Louis Pasteur, language, and molecular chirality. I. Background and dissymmetry.

    2011-01-01

    Louis Pasteur resolved sodium ammonium (±)-tartrate in 1848, thereby discovering molecular chirality. Although hindered by the primitive state of organic chemistry, he introduced new terminology and nomenclature for his new science of molecular and crystal chirality. He was well prepared for this task by his rigorous education and innate abilities, and his linguistic achievements eventually earned him membership in the supreme institution for the French language, the Académie française. Dissymmetry had been in use in French from the early 1820s for disruption or absence of symmetry or for dissimilarity or difference in appearance between two objects, and Pasteur initially used it in the latter connotation, without any reference to handedness or enantiomorphism. Soon, however, he adopted it in the meaning of chirality. Asymmetry had been in use in French since 1691 but Pasteur ignored it in favor of dissymmetry. The two terms are not synonymous but it is not clear whether Pasteur recognized this difference in choosing the former over the latter. However, much of the literature mistranslates his dissymmetry as asymmetry. Twenty years before Pasteur the British polymath John Herschel proposed that optical rotation in the noncrystalline state is due to the "unsymmetrical" [his term] nature of the molecules and later used dissymmetrical for handed. Chirality, coined by Lord Kelvin in 1894 and introduced into chemistry by Mislow in 1962, has nearly completely replaced dissymmetry in the meaning of handedness, but the use of dissymmetry continues today in other contexts for lack of symmetry, reduction of symmetry, or dissimilarity.

The survey included measurements of the following: residual alpha and beta-gamma contamination levels in the existing buildings that were used in the uranium projects; external gamma radiation levels at 1 m above the surface in these buildings and outdoors around these buildings; radon and radon daughter concentrations in the air in these buildings; uranium, radium, actinium, and thorium concentrations in surface and subsurface soil on the site; concentrations of radionuclides in water and sediment found in drains both inside and outside the buildings; and concentrations of radionuclides in ground and surface water on the site and in river water taken near the site. Alpha and beta-gamma contamination levels inside and outside some of the buildings were above limits set by current federal guidelines concerning the release of property for unrestricted use. Elevated external gamma radiation levels were measured at some outdoor locations and in some of the buildings. Licensable concentrations of uranium were found in soil at some places, and the concentration of uranium in a water sample taken from a core hole between Buildings 100 and 101 was in excess of limits set by current federal standards. Radon and radon daughter concentrations in three buildings were in excess of current federal guidelines for nonoccupational radiation exposure.

  10. Skewed Riskscapes and Environmental Injustice: A Case Study of Metropolitan St. Louis

    Abel, Troy D.

    2008-08-01

    This article presents a case study of Toxics Release Inventory (TRI) air pollution exposure risks across metropolitan St. Louis. The first section critically reviews environmental justice research and related barriers to environmental risk management. Second, the paper offers a conventional analysis of the spatial patterns of TRI facilities and their surrounding census block group demographics for metropolitan St. Louis. Third, the article describes the use of an exposure risk characterization for 319 manufacturers and their air releases of more than 126 toxic pollutants. This information could lead to more practical resolutions of urban environmental injustices. The analysis of TRIs across metropolitan St. Louis shows that minority and low-income residents were disproportionately closer to industrial pollution sources at nonrandom significance levels. Spatial concentrations of minority residents averaged nearly 40% within one kilometer of St. Louis TRI sites compared to 25% elsewhere. However, one-fifth of the region’s air pollution exposure risk over a decade was spatially concentrated among only six facilities on the southwestern border of East St. Louis. This disproportionate concentration of some of the greatest pollution risk would never be considered in most conventional environmental justice analyses. Not all pollution exposure risk is average, and the worst risks deserve more attention from environmental managers assessing and mitigating environmental injustices.

  11. Target population involvement in urban ciclovias: a preliminary evaluation of St. Louis open streets.

    Ciclovias are active street events when roads are open to walkers, cyclists, and families and closed to automobiles. Over 70 cities in the USA have implemented ciclovias to promote physical activity. The authors evaluated four events during 2010 to determine what activities participants perform and who is attending. For two ciclovia events in St. Louis, Missouri, observation reports of activities, gender, and age of 1,452 participants were collected, and 82 adults were interviewed via direct approach. The survey covered six domains: physical activity, travel to event, sense of community, marketing, economic impact, and demographics. Each event occurred within the city, along multiple streets. Domains were selected from Ciclovia Recreativa developed by Ciclovia Bogota, Pan American Health Organization, and CDC. Additional questions addressed city-specific goals and matched similar evaluations in other cities. Over 50 % of participants met CDC-defined weekly minute thresholds for physical activity. Participants, primarily (>80 %) middle class, college educated, and white, were not representative of the majority minority city population, which has high rates of poverty, and low percentage of college graduates. Cities must work with residents to increase low-income minority population participation in ciclovia-based physical activity. PMID:22948790

    2015-04-01

    One of the fathers of pediatric surgery in France, Louis Ombrédanne (1871-1956) was a great plastic surgeon. During his residency he was initiated to plastic surgery by Charles Nélaton (1851-1911). Both wrote two books: "La rhinoplastie" and "Les autoplasties", taking stock of these techniques in the early 20th century. In 1906, he was the first to describe the pectoral muscle flap for immediate breast reconstruction after mastectomy. He used this flap in conjunction with an axillo thoracic flap. From 1908 to 1941, Louis Ombrédanne practised pediatric surgery, most of which was devoted in reconstruction of congenital and acquire anomalies. From 1924 to 1941, he was Professor of pediatric surgery at the hospital Enfants-Malades in Paris. In 1907, Louis Ombrédanne created a prototype of an ether inhaler as a safe anesthetic device. The device was successfully used for fifty years in Europe.

    1993-09-23

    The Arrowhead Refinery National Priorities List (NPL) site is located in St. Louis County about 8 miles northwest of Duluth in Hermantown, Minnesota. Prior to 1945 the 10 acre site was used for retinning milk cans and then was converted to recycling waste oil. Samples taken from the site during two large scale investigations have shown a variety of contaminants present in soil, sediment, groundwater and in a natural lagoon containing waste sludge. The sludge has been found to be very corrosive, with high concentrations of metals as well as toxic and carcinogenic organic compounds. Monitoring of air quality on and near the site has not been done. However, odors apparently from the oily sludge have been detected off-site. The Agency for Toxic Substances and Disease Registry (ATSDR) and MDH consider the site to be a public health hazard.

The fundamental procedures that Louis created in the ten years he occupied the position of Director General are still used today, especially in regard to disease reporting, drafting of final reports of meetings and conferences. Gifted with exceptional linguistic skills and writing style in French, Spanish and English, he could spend hours perfecting a text.He was greatly respected and admired by the representatives of member countries. His knowledge of many different cultures and languages was comprehensive and extensive. He was conscious of the widening gap between developed and developing countries and was always supportive of and attentive to the concerns expressed by less economically privileged nations.He ensured that the OIE staff received health cover and that regulations were drafted and a pension fund created for all members of staff. Despite his important and influential position, he remained modest and was always keen to listen to and share his good humour with colleagues at all levels. He valued his friendships and continued to correspond with and meet delegates and specialists of member countries during the twenty years after he left the OIE.During his retirement, Louis was the driving force behind the book entitled L’histoire des services vétérinaires français (History of the French Veterinary Services… a mammoth task.Louis was a warm man, had a wonderful sense of humour and is remembered by many as ‘a true gentleman’.

  1. St. Louis Airport site: Annual site environmental report, Calendar Year 1986

    International Nuclear Information System (INIS)

    During 1986, the environmental monitoring program was continued at the St. Louis Airport Site (SLAPS) in St. Louis County, Missouri. The ditches north and south of the site were designated for cleanup as part of the Formerly Utilized Sites Remedial Action Program (FUSRAP), a United States Department of Energy (DOE) program to identify, decontaminate, or control sites where residual radioactive material remains from the early years of the nation's atomic energy program. The site is currently controlled by the St. Louis Airport Authority. The monitoring program measures radon gas concentrations in air; external gamma dose rates; and uranium, thorium, and radium concentrations in surface water, groundwater, and sediment. The radiation dose was calculated for the maximally exposed individual. Based on the scenario described in this report, the maximally exposed individual would receive an external exposure approximately equivalent to 4.7 percent of the DOE radiation protection standard of 100 mrem/yr. The dose to the population within an 80-km (50-mi) radius of the SLAPS that would result from radioactive materials present at the site would be indistinguishable from the dose the population would receive from naturally occurring radioactive sources. 12 refs., 5 figs., 10 tabs

    Dell' Orco, L.; Chambers, D.

    2002-02-27

    Non-Federally owned radioactively contaminated sites in St. Louis, Missouri are currently being remediated by the St. Louis District Corps of Engineers under the Formerly Utilized Sites Remedial Action Program (FUSRAP). When FUSRAP remediation is complete, inaccessible soils which have levels of contamination greater than unrestricted use standards, will remain. The purpose of this paper is to document the initial challenges facing the project team during its development of the Long Term Stewardship plan for the management of these soils. These soils are located under buildings, roads, railroads and bridges. The Long Term Stewardship plan for the majority of the sites is being developed simultaneously with the remedy selection process. A living document, it will ultimately document the remedial action end state and location of inaccessible soils and implement the plan for ensuring these soils are not a threat to human health and the environment. Although these soils are protective in their current configuration, at some point in time, when activities such as maintenance, utility or property improvement occur, the soils will become accessible and need to be addressed by the federal government. Up until that point in time they will need to be effectively managed to ensure they remain protective. The St. Louis District is in the process of collaboratively developing this plan with its regulators, affected stakeholders and interested parties.

Analysis of HCMM data shows that an urban heat island exists day and night in all seasons when clear skies prevail. The lower albedo value of the urban region during the day suggests that the higher temperatures are due to more absorption of solar radiation. Preliminary analysis of in situ meteorological data was performed after merging with HCMM data, and surface roughness, the exchange coefficient, and the soil moisture were calculated.

    Louis Pasteur long has been heralded as the "father of modern hygiene, public health and much of modern medicine," despite early controversies regarding his findings and methodology. A recently published biography, however, has shed new light on both Pasteur's scientific acumen and integrity. Reactions to this portrayal have been mixed. This article provides an overview of Pasteur's life and the debate regarding his scientific discoveries and honesty that has ensued for more than 100 years, with insights gained from both supporters and critics of the new biography by Gerald L. Geison.

    This paper examines the history of St. Louis, Missouri in coping with flood risk over the past 15 years, with a focus on flood insurance. Six challenges to the continued management of riverine flood risk are identified and discussed. They are (1) many property owners don’t buy flood insurance, (2) people underestimate flood risk, (3) we need better flood maps, (4) we have a “love affair” with levees, (5) flood risk is increasing over time, and (6) we take deep pride in rebuilding after a disa...

    The results are presented of processing plant evaluations of the St. Louis-Union Electric Refuse Fuel Project, including equipment and facilities as well as assessment of environmental emissions at both the processing and the power plants. Data on plant material flows and operating parameters, plant operating costs, characteristics of plant material flows, and emissions from various processing operations were obtained during a testing program encompassing 53 calendar weeks. Refuse derived fuel (RDF) is the major product (80.6% by weight) of the refuse processing plant, the other being ferrous metal scrap, a marketable by-product. Average operating costs for the entire evaluation period were $8.26/Mg ($7.49/ton). The average overall processing rate for the period was 168 Mg/8-h day (185.5 tons/8-h day) at 31.0 Mg/h (34.2 tons/h). Future plants using an air classification system of the type used at the St. Louis demonstration plant will need an emissions control device for particulates from the large de-entrainment cyclone. Also in the air exhaust from the cyclone were total counts of bacteria and viruses several times higher than those of suburban ambient air. No water effluent or noise exposure problems were encountered, although landfill leachate mixed with ground water could result in contamination, given low dilution rates.

    In 1992 the painting 'The anatomy of professor Louis Bolk' by the Dutch painter Martin Monnickendam (1874-1943), was finally returned to its place in the 'Tulp-room' of the Department of Anatomy and Embryology at the University of Amsterdam, after the department had been moved to new premises in 1985. The professor of anatomy at the University of Amsterdam, Louis Bolk, is seated in the middle surrounded by his, at that time, former pupils, from left to right: Boeke, Barge and van den Broek, authors of a Dutch textbook of anatomy. The four professors are gathered around a cadaver of an orang-utan, placed not on a dissection table but on a console. Bolk is facing the observer and holding a scalpel in one hand while steadying the animal's head with the other; he is ready to make an incision. In the back of the painting a bust of the 18th century anatomist Petrus Camper is visible. The four professors all wear a white coat over their suits. Bolk finishes this off with an artistic bow tie whilst the others use an ordinary necktie. The painting is signed in the left upper corner 'Martin Monnickendam 1925'. PMID:8277996

  14. Estimating sources of elemental and organic carbon and their temporal emission patterns using a Least Squares Inverse model and hourly measurements from the St. Louis-Midwest Supersite

    Full Text Available An inverse model was used to evaluate emission inventories of Elemental Carbon (EC and Organic Carbon (OC based on year-long hourly time series from the St. Louis-Midwest Supersite. The input to the model consisted of continuous measurements of EC and OC obtained for 2002 using two semicontinuous analyzers. High resolution meteorological simulations were performed for the entire time period using the Weather Research and Forecasting model (WRF. These were used to simulate hourly back-trajectories at the measurement site using a Lagrangian model (FLEXPART-WRF. In combination, an Eulerian model (CAMx was used to simulate the impacts at the measurement site using known emissions inventories for point and area sources as well as for open burning. By considering only passive transport of pollutants, and by using diagonal error covariance matrices, the Bayesian inversion simplifies to a single least squares inversion. The inverse model combines forward Eulerian simulations with backward Lagrangian simulations to yield estimates of emissions from sources in current inventories as well as from area emissions that might be missing in the inventories. The CAMx impacts were disaggregated into separate time chunks in order to determine improved diurnal, weekday and monthly temporal patterns of emissions. Because EC is a primary species, the inverse model estimates can be interpreted directly as emissions. In contrast, OC is both a primary and a secondary species. As the inverse model does not differentiate between direct emissions and formation in the plume of those direct emissions, the estimates need to be interpreted as contributions to measured concentrations. Emissions in the St. Louis region from On-Road, Non-Road, Marine/Aircraft/Railroad (MAR, "Other" and Point Sources were revised slightly downwards on average. In particular, both MAR and Point Sources had a more pronounced diurnal variation than in the inventory. The winter peak in Other emissions

  16. St. Louis airport site: Annual site environmental report, St. Louis, Missouri, Calendar Year 1988: Formerly Utilized Sites Remedial Action Program (FUSRAP)

    International Nuclear Information System (INIS)

    The monitoring program at St. Louis Airport Site (SLAPS) measures radon concentrations in air; external gamma dose rates; and uranium, thorium, and radium concentrations in surface water, groundwater, and sediment. To assess the potential effects of SLAPS on public health, the potential radiation dose was estimated for a hypothetical maximally exposed individual. Based on the scenario described in this report, this hypothetical individual would receive an external exposure approximately equivalent to 7.5 percent of the DOE radiation protection standard of 100 mrem/yr. This exposure is approximately the same as a person receives during two round-trip flights from New York to Los Angeles (because of greater amounts of cosmic radiation at higher altitudes). The cumulative dose to the population within an 80-km (50-mi) radius of SLAPS that results from radioactive materials present at the site is indistinguishable from the dose the same population receives from naturally occurring radioactive sources. Results of 1988 monitoring show that SLAPS is in compliance with the DOE radiation protection standard. 18 refs., 13 figs., 13 tabs

    Ruffe (Gymnocephalus cernuus), were accidentally introduced into the St. Louis River estuary, western Lake Superior, in the mid 1980s and it was feared that they might affect native fish through predation on eggs and competition for forage and habitat. In an effort to control the abundance of ruffe and limit dispersal, a top-down control strategy using predators was implemented in 1989. We used bioenergetics modeling to examine the efficacy of top-down control in the St. Louis River from 1991 to 1994. Five predators--northern pike (Esox lucius), walleye (Stizostedion vitreum vitreum), smallmouth bass (Micropterus dolomieui), brown bullhead (Ictalurus nebulosus), and yellow perch (Perca flavescens)--were modeled to determine their consumption of ruffe and four other native prey species-spottail shiner (Notropis hudsonius), emerald shiner (Notropis atherinoides), yellow perch (Perca flavescens), and black crappie (Pomoxis nigromaculatus). Although predators ate as much as 47% of the ruffe biomass in 1 year, they were not able to halt the increase in ruffe abundance. The St. Louis River is an open system that allows predators to move freely out of the system, and the biomass of managed predators did not increase. A selectivity index showed all five predators selected the native prey and avoided ruffe. The St. Louis River has several predator and prey species creating many complex predator-prey interactions; and top-down control of ruffe by the predators examined in this study did not occur.

  4. Geochemical information for sites contaminated with low-level radioactive wastes: II. St. Louis Airport Storage Site

    International Nuclear Information System (INIS)

    The St. Louis Airport Storage Site (SLASS) became radioactively contaminated as a result of wastes that were being stored from operations to recover uranium from pitchblende ores in the 1940s and 1950s. The US Department of Energy is considering various remedial action options for the SLASS under the Formerly Utilized Site Remedial Action Program (FUSRAP). This report describes the results of geochemical investigations, carried out to support the FUSRAP activities and to aid in quantifying various remedial action options. Soil and groundwater samples from the site were characterized, and sorption ratios for uranium and radium and apparent concentration limit values for uranium were measured in soil/groundwater systems by batch contact methodology. The uranium and radium concentrations in soil samples were significantly above background near the old contaminated surface horizon (now at the 0.3- to 0.9-m depth); the maximum values were 1566 μg/g and 101 pCi/g, respectively. Below about the 6-m depth, the concentrations appeared to be typical of those naturally present in soils of this area (3.8 +- 1.2 μg/g and 3.1 +- 0.6 pCi/g). Uranium sorption ratios showed stratigraphic trends but were generally moderate to high (100 to 1000 L/kg). The sorption isotherm suggested an apparent uranium concentration limit of about 200 mg/L. This relatively high solubility can probably be correlated with the carbonate content of the soil/groundwater systems. The lower sorption ratio values obtained from the sorption isotherm may have resulted from changes in the experimental procedure or the groundwater used. The SLASS appears to exhibit generally favorable behavior for the retardation of uranium solubilized from waste in the site. Parametric tests were conducted to estimate the sensitivity of uranium sorption and solubility to the pH and carbonate content of the system

    Philately is an important source of knowledge on numerous items. Evocation of Louis Pasteur's as well as his disciples life and works throughout stamp collection is a perfect example of this. Born in Dôle in 1822, he spent his youth in Arbois. It is at the Ecole normale supérieure that he performed his work on cristals which led him to establish molecular dissymetry principles. Later, he studied of the fermentation process, he searched the reason of wines' disease and the means to prevent it (i.e. pasteurisation), he solved the problem of the silkworm disease and discovered agents of numerous infectious diseases. He demonstrated scientifically the vaccination principle. In 1885 he tried with success the first human antirabic vaccination. Three years later, the Pasteur Institute was inaugurated. After his death, his works survived in numerous institutes all over the world. Many pasteurians received the Nobel Prize.

    Full Text Available In a much-quoted interview with Richard Wagner conducted by the French critic Louis de Fourcaud in 1879, and published in different versions in 1880, 1884, and 1886, the composer allegedly advised the French to write operas drawing on their own legendary sources. Contemporary works such as d’Indy’s Fervaal, Chausson’s Le Roi Arthus, and Massenet’s Esclarmonde suggest that Fourcaud’s interview did indeed have a profound impact on the Wagnerian movement in France. However, a close examination of the sources reveals that his text owes much less to Wagner than scholars have previously assumed: in fact, evidence suggests that the most important part of the interview (that is, the advice to French composers was added by Fourcaud himself after Wagner’s death.

    Full Text Available Bien que la Révolution française ait suscité l’intérêt des chercheurs du monde entier, Louis xvi fait figure de parent pauvre des études universitaires. Même si c’est à son corps défendant, il en est tout de même l’un des principaux protagonistes et la Révolution s’est aussi construite en interrogeant le rôle et la place du roi. Cette situation a eu pour conséquence de conserver vivace la légende dorée que le roi s’est construite en exerçant un contrôle sur son image dès le début de son règne. Elle l’assimile à un nouvel Henri iv, profondément concerné par les maux de ses sujets. Malgré les attaques de la Révolution, cette image continue à exercer une influence considérable sur les biographes de Louis xvi et les historiens de la Révolution.Si la Restauration en a fait un usage sans surprise, elle a, de manière plus étonnante, séduit jusqu’à Jaurès avant de souffrir du discrédit dans lequel sombre le royalisme en choisissant l’antisémitisme au xxe siècle. Néanmoins, c’est aujourd’hui par le détour de l’historiographie anglo-saxonne qu’elle fait sa réapparition et commence seulement à être questionnée.Although the French Revolution has aroused interest of international researchers, Louis xvi is widely neglected by the academic studies. Even if reluctantly, he is yet one of the main protagonists and it is also by questioning the role and the place of the king that the Revolution took its shape.This led to the consequence that the golden legend the king constructed by controlling his image from the beginning of his reign is still very lively today. In it, he is presented as a new Henri iv, deeply concerned by the misfortunes of his subjects. In spite of the attacks of the Revolution, this image still considerably influences Louis xvi’s biographers and the historians of the Revolution.If the Restoration made a not surprising good use of it, it more astonishingly seduced Jaur

    St. Louis encephalitis virus (SLEV) and West Nile virus (WNV) belong to the Japanese encephalitis antigenic complex (Flavivirus genus, Flaviviridae family). They show antigenic close relationships and share many similarities in their ecology. Both are responsible for serious human diseases. The aim of this study was to investigate the presence of neutralizing antibodies to these viruses in horses from Uruguay. To do this, 425 horse sera were collected in 2007 and analyzed by plaque reduction neutralization tests. As a result, 205 sera (48.2%) were found positive for SLEV, with titers ranging between 10 and 80. Two sera remained inconclusive, since they showed low titers to WNV and SLEV (10 and 20), not allowing us to demonstrate activity of WNV in our territory. This is the first report of circulation of SLEV in horses in Uruguay.

    Louis XIV ( September 1638—Sep-tember 1715 ) , known as Louis the Great or the Sun King, was a monarch of the House of Bourbon who ruled as King of France from 1643 until his death.His reign of 72 years and 110 days is the longest of any monarch of a major country in Euro-pean history.As a legendary king in European his-tory, Louis XIV did not expect the Enlightenment, but instead, he experienced the beginning period of the concept of “nation”.During his entire life, the public image of Louis XIV was represented in different forms and occasions:in paintings and en-gravings, medals and sculptures, plays, ballets, and operas.It is the place of Louis XIV in the col-lective imagination that Burke focuses on.All these contemporary representations of Louis XIV is the material for Peter Burke to show how the making of a royal image illuminates the relationship between art and power, between fabricating a king and the rising up of nationalism.Burke stresses that during Louis XIV's tenure, by introducing the idea of e-quality and freedom, the concept of “nation” be-gan to undermine the legitimacy of kingship char-acterized by oracle and hierarchy.While Benedict Anderson believes that the history of the nation-state is the history of imagination and a fixing of ethnic borders, and that a nation is a imagined po-litical community, Burke illustrates another way for the forming of national identity: by fabricating a hero, an exemplary and a center.Therefore, The Fabrication of Louis XIV provides an inspiring per-spective to rethink the rise of nationalism and a way of creating identity.

  14. De Louis Delluc à Caligari... L'introduction du cinéma allemand en France

    Full Text Available Dès 1919, le boycott du cinéma allemand interdit toute confrontation avec les réalisations de l'ennemi héréditaire. Cette négation inquiète Louis Delluc qui réagit en publiant deux articles sur la situation du cinéma allemand. Ces chroniques proposent un premier état des lieux mais, sans film distribué, ces analyses restent lettre morte et ne font que souligner ce manque. Il faut attendre 1921 et la création de la revue Cinéa pour que Delluc organise la première projection du Cabinet du docteur Caligari. Cet événement prend vite une ampleur nationale. Le succès mondial de ce film démontre la possibilité d'un équilibre entre industrie mondialisée et spécificité nationale. Dès lors, le cinéma allemand peut servir de modèle pour la recherche d'une telle unité au sein du cinéma français dont la crise structurelle démontre son incapacité à s'adapter aux nouvelles exigences du marché global. Louis Delluc parvient donc à imposer les productions allemandes en France, mais il ne réussit cependant pas à effectuer la transition entre artisanat anarchique et industrie cinématographique rationalisée. Ainsi, une autre unité voit-elle le jour, dépassant les cadres nationaux pour s'inscrire sur le vaste espace européen ouvrant ainsi la voie à des échanges culturels et techniques franco-allemands.Seit 1919 verhindert das Verbot des deutschen Kinos in Frankreich jegliche Konfrontation mit den Produktionen des Erzfeindes. Diese Ablehnung des deutschen Films beschäftigt und beunruhigt Louis Delluc, der daraufhin zwei Artikel über die Situation des deutschen Films veröffentlicht. Seine Artikel zeigen einen ersten Stand der Dinge auf, der aber in Anbetracht fehlender deutscher Filmvorführungen keine weitere Beachtung findet. Erst im Jahr 1921 wird mit der Revue Cinéa, deren Gründer Delluc ist, eine erste Aufführung des Kabinett des Dr. Caligari organisiert. Dieses Ereignis nimmt schnell nationale Dimensionen an. Der

    1982-01-01

    Coal-tar derivatives from a coal-tar distillation and wood-treating plant that operated from 1918 to 1972 at St. Louis Park, Minnesota contaminated the near-surface ground water. Solutions of phenolic compounds and a water-immiscible mixture of polynuclear aromatic compounds accumulated in wetlands near the plant site and entered the aquifer. The concentration of phenolic compounds in the aqueous phase under the wetlands is about 30 mg/1 but decreases to less than 0.2 mg/1 at a distance of 430 m immediately downgradient from the source. Concentrations of naphthalene (the predominant polynuclear compound in the ground water) and sodium (selected as a conservative tracer) range from about 20 mg/1 and 430 mg/1 in the aqueous phase at the source to about 2 mg/1 and 120 mg/1 at 430 m downgradient, respectively. Phenolic compounds and naphthalene are disappearing faster than expected if only dilution were occurring. Sorption of phenolic compounds on aquifer sediments is negligible but naphthalene is slightly sorbed. Anaerobic biodegradation of phenolic compounds is primarily responsible for the observed attenuation. Methane was found only in water samples from the contaminated zone (2-20 mg/1). Methane-producing bacteria were found only in water from the contaminated zone. Methane was produced in laboratory cultures of contaminated water inoculated with bacteria from the contaminated zone. Evidence for anaerobic biodegradation of naphthalene under either field or laboratory conditions was not obtained.

    We describe hatching and the morphological and meristic characteristics of 2.5-5.6 mm long ruffe protolarvae (Gymnocephalus cernuus). Eggs and sperm from St. Louis River ruffe were mixed, producing fertilized eggs that were 0.9-1.2 mm in diameter. Newly hatched protolarvae were 2.5-3.2 mm long. They had 14-15 preanal and 23-24 postanal myomeres, a continuous finfold of even width, unpigmented eyes, and a large anterior oil globule in the yolk sac, and the head deflected over the yolk sac. Pectoral fin buds appeared on the dorsal side of the yolk sac 5 hours after hatching. Two-day-old protolarvae had fully pigmented eyes, and the head was free from the yolk sac. Three-day-old protolarvae were 3.9-4.3 mm long and possessed opercula, gills, pectoral fins, and a functional jaw. Feeding and swimming began about one week after hatching when the yolk sac was almost completely absorbed. Protolarvae grew rapidly at 20-22 degrees C and were 4.9-5.6 mm long after 13 days. Newly hatched ruffe protolarvae are distinguished from other Lake Superior percids by having the fewest preanal myomeres (14-15), the head deflected over the yolk sac, continuous finfold of even width, and a total length of less than 4.0 mm.

  18. Geochemical factors influencing the production and transport of methylmercury in St. Louis River Estuary sediment

    International Nuclear Information System (INIS)

    Highlights: • Results are presented from lab study on sulfate-impacted freshwater estuary sediment. • In the lab study, sulfate in overlying water affected SRB abundance in sediment. • In the lab study, sulfate in overlying water did not affect sediment solid-phase MeHg. • Estimated dissolved MeHg flux from SLRE sediment is less than upstream MeHg inputs. - Abstract: The production of methylmercury (MeHg), a bioaccumulative neurotoxin, in freshwater systems is primarily driven by naturally occurring sulfate reducing bacteria in anoxic sediment and waters. This research used laboratory microcosms to examine the influence of sulfate on MeHg production and partitioning in sulfate-impacted freshwater estuary sediment. A laboratory sulfate addition experiment exposed 20 cm diameter intact sediment cores with varying organic carbon content to sulfate concentrations in the overlying water ranging from 5 to 50 mg L−1. Results from the 6 month incubation suggest that net MeHg production in sediment from open-water areas of the St. Louis River Estuary was not directly related to overlying water sulfate. Mercury mobility, as indicated by porewater concentrations, appeared to be related to the quantity of organic carbon and sulfur in sediment. Laboratory flux estimates were consistent with porewater concentrations and provided a means to compare diffusion-driven MeHg loading from sediment to MeHg loading from upstream sources

    Full Text Available Introduction Arboviruses are an important public health problem in Brazil, in especially flaviviruses, including the Saint Louis encephalitis virus (SLEV and the Rocio virus (ROCV, are especially problematic. These viruses are transmitted to humans or other vertebrates through arthropod bites and may cause diseases with clinical manifestations that range from asymptomatic infection, viral hemorrhagic fever to encephalitis. Methods A serological survey of horses from various regions of Brazil using an enzyme-linked immunosorbent assay (ELISA with recombinant SLEV domain III peptides and ROCV E protein as antigens. Results Overall, 415 (55.1% of the 753 horses that were screened were seropositive for flavivirus and, among them, monotypic reactions were observed to SLEV in 93 (12.3% and to ROCV in 46 (6.1%. These results suggested that these viruses, or other closely related viruses, are infecting horses in Brazil. However, none of the studied horses presented central nervous system infection symptoms. Conclusions Our results suggest that SLEV and ROCV previously circulated among horses in northeast, west-central and southeast Brazil.

    Were he alive today, would Louis Pasteur still champion culture methods he pioneered over 150 years ago for identifying bacterial pathogens? Or, might he suggest that new molecular techniques may prove a better way forward for quickly detecting the true microbial diversity of wounds? As modern clinicians faced with treating complex patients with diabetic foot infections (DFI), should we still request venerated and familiar culture and sensitivity methods, or is it time to ask for newer molecular tests, such as 16S rRNA gene sequencing? Or, are molecular techniques as yet too experimental, non-specific and expensive for current clinical use? While molecular techniques help us to identify more microorganisms from a DFI, can they tell us 'who done it?', that is, which are the causative pathogens and which are merely colonizers? Furthermore, can molecular techniques provide clinically relevant, rapid information on the virulence of wound isolates and their antibiotic sensitivities? We herein review current knowledge on the microbiology of DFI, from standard culture methods to the current era of rapid and comprehensive 'crime scene investigation' (CSI) techniques.

  1. Science and the applications of science from Louis Pasteur to Jacques Monod.

    2015-06-01

    Jacques Monod's ideas on the applications of science came within the scope of a long tradition at the Institut Pasteur. Louis Pasteur, whose scientific career was characterized by a permanent come and go between science and its applications, long opposed the idea of getting any income from his research, until the financial needs of the Institut Pasteur made him change his mind. As for Jacques Monod, he remained a fervent supporter of basic science during his whole scientific career. However, once he became director of the Institut Pasteur, he realized that the applications of research had to be developed to support the institute from a financial point of view. Thus, he reorganized the valorization of research in the institute, through an incitation of scientists to develop projects with possible applications, and by creating a company, Institut Pasteur Production, for which he had a factory built, and which was in charge of producing and commercializing the vaccines and reagents stemming from the research at the Institut Pasteur.

    2014-01-01

    The biography of the physician general Alain Jean Georges (1946-2012) shows the exceptional career of a military physician-clinical pathologist specialized in tropical medicine and educated at the Navy Health School in Bordeaux and the Pharo School in Marseille. He completed his education at the Institut Pasteur de Paris in courses still conducted in the spirit of those taught by Louis Pasteur. In 1979, he became director of the Pasteur Institute of Bangui, following in the steps of Eugène Jamot, in the long tradition of military doctors from the Institut Pasteur overseas network committed to a career in Africa. For more than 12 years, Alain Georges directed the Pasteur Institute of Bangui, one of the last citadels of French postcolonial military medicine, in a very personal and charismatic style. He was thus a pioneer in research about both AIDS in Africa and hemorrhagic fevers. His methods were widely misunderstood later as the traditional networks of French biomedical research in its former African colonies modernized and opened internationally, including to national elites. Alain Georges was probably one of the last important figures of the golden age of French colonial medicine.

    Full Text Available We prospectively sampled flavivirus-naïve horses in northern Colombia to detect West Nile virus (WNV and St. Louis encephalitis virus (SLEV seroconversion events, which would indicate the current circulation of these viruses. Overall, 331 (34.1% of the 971 horses screened were positive for past infection with flaviviruses upon initial sampling in July 2006. During the 12-month study from July 2006-June 2007, 33 WNV seroconversions and 14 SLEV seroconversions were detected, most of which occurred in the department of Bolivar. The seroconversion rates of horses in Bolivar for the period of March-June 2007 reached 12.4% for WNV and 6.7% for SLEV. These results comprise the first serologic evidence of SLEV circulation in Colombia. None of the horses sampled developed symptoms of encephalitis within three years of initial sampling. Using seroconversions in sentinel horses, we demonstrated an active circulation of WNV and SLEV in northern Colombia, particularly in the department of Bolivar. The absence of WNV-attributed equine or human disease in Colombia and elsewhere in the Caribbean Basin remains a topic of debate and speculation.

    Full Text Available The molecular characterization of SPH253157, a new strain of St. Louis encephalitis virus (SLEV, isolated in 2004 from the first case of human infection recognized in the state of São Paulo, Brazil, is reported. The patient, presenting a febrile illness without neurological involvement, was hospitalized as a probable case of dengue fever. Genomic RNA was isolated from the supernatant of C6/36 cells infected with acute phase-serum specimen of the patient and the envelope gene was amplified by reverse-transcription-polymerase chain reaction. The complete nucleotide sequence of the envelope gene of this isolate was directly sequenced from the amplified products and compared with other Brazilian and American SLEV strains. Phylogenetic analyses were carried out under maximum likelihood criterion with outgroups both included and excluded. Outgroups comprised four flavivirus of the Japanese encephalitis group. Phylogeny also included Bayesian analysis. The results indicated that the new SLEV isolate belongs to lineage III, being closely related to an Argentinean strain recovered from Culex sp. in 1979. It is concluded that there are at least 3 lineages of SLEV in Brazil.

    Full Text Available Saint Louis encephalitis virus (SLEV is a member of the Japanese-encephalitis virus serocomplex of the genus Flavivirus. SLEV is broadly distributed in the Americas and the Caribbean Islands, where it is usually transmitted by mosquitoes of the genus Culex and primarily to birds and mammalian-hosts. Humans are occasionally infected by the virus and are dead-end hosts. SLEV causes encephalitis in temperate regions, while in tropical regions of the Americas, several human cases and a wide biological diversity of SLEV-strains have been reported. The phylogenetic analysis of the envelope (E protein genes indicated eight-genotypes of SLEV with geographic overlap. The present paper describes the genotyping of two SLEV viruses detected in mosquito-pools collected in northern Colombia (department of Cordoba. We used reverse transcription-polymerase chain reaction to amplify a fragment of theE-gene to confirm the virus identity and completeE-gene sequencing for phylogenetic analysis and genotyping of the two-SLEV viruses found circulating in Córdoba. This is the first report of SLEV genotype IV in Colombia (Córdoba in mosquitoes from a region of human inhabitation, implicating the risk of human disease due to SLEV infection. Physicians should consider SLEV as a possible aetiology for undiagnosed febrile and neurologic syndromes among their patients who report exposure to mosquito-bites.

    Full Text Available Objective. To identify social, behavioral, and physiological risk factors associated with small for gestational age (SGA by gestational age category in St. Louis City and County. Methods. A retrospective cohort study was conducted using birth certificate and fetal death records from 2000 to 2009 (n = 142,017. Adjusted associations of risk factors with SGA were explored using bivariate logistic regression. Four separate multivariable logistic regression analyses, stratified by gestational age, were conducted to estimate adjusted odds ratios. Results. Preeclampsia and inadequate weight gain contributed significantly to increased odds for SGA across all gestational age categories. The point estimates ranged from a 3.41 increased odds among women with preeclampsia and 1.76 for women with inadequate weight gain at 24–28 weeks’ gestational age to 2.19 and 2.11 for full-term infants, respectively. Among full-term infants, smoking (aOR = 2.08, chronic hypertension (aOR = 1.46, and inadequate prenatal care (aOR = 1.25 had the next most robust and significant impact on SGA. Conclusion. Preeclampsia and inadequate weight gain are significant risk factors for SGA, regardless of gestational age. Education on the importance of nutrition and adequate weight gain during pregnancy is vital. In this community, disparities in SGA and smoking rates are important considerations for interventions designed to improve birth outcomes.

    Full Text Available The National Service Training Program (NSTP of the Philippines is a form of service learning which is defined as the integration of community services to instruction in order to strengthen the civic and community responsibilities of the students. The purpose of this study is to determine the effectiveness of the NSTP for the students, its influences along self-improvement, performance, community involvement, and demonstration of abilities and skills, and the difficulties encountered by the students while enrolled in their respective NSTP courses. The 1421 respondents of the study were the undergraduate students of Saint Louis University who finished the NSTP courses last school year 2012-2013. The study utilized an adapted survey-type questionnaire to gather the data needed in the study. The findings of the study suggest that NSTP courses are effective and they influenced the self-improvement, performance, community involvement, and demonstration of abilities and skills of the students to an extent. The students are also able to continue to demonstrate the different competencies they learned or acquired from NSTP courses. Moreover, this study reveals that the students often encountered many difficulties while they were enrolled in the NSTP courses.

  8. Politica e censura nella Francia di Louis XIV: Chavigny de La Bretonnière

    Directory of Open Access Journals (Sweden)

    Chiara Mainardi

    2012-04-01

    Full Text Available During the reign of Louis XIV French libertines were expressing their intellectual dissent by opposing absolutism and criticising historical and religious conflicts. While in France, before abrogating the Edict of Nantes, any opposition was suppressed, Chavigny de La Bretonnière supported a revolt against the Church and political power. The prominent role of clandestine literature in Old Regime France will be analysed in this paper by considering critical studies about libertinage. In particular, the political and antireligious discourse carried on by this author will be highlighted by taking into account his ‘lardons’, satirical articles against French government, his erotic novel La Religieuse en chemise and his ecclesiastic pamphlet Le Cochon mitré. In a true editorial campaign, Chavigny de La Bretonnière attaches French royal power, through the use of satire he depicts corrupted prelates as obscene creatures and he reforms libertine dialogue by enhancing broad political purposes. As a response to his critics and claims, Chavigny was kidnapped, tortured and imprisoned for life. His name disappeared from history.

    Analysis of 287 soil, sediment and house dust samples collected in a 200 km(2)-zone in northern St. Louis County, Missouri, establish that offsite migration of radiological contaminants from Manhattan Project-era uranium processing wastes has occurred in this populated area. Specifically, 48% of samples (111 of a subset of 229 soils and sediments tested) had (210)Pb concentrations above the risk-based soil cleanup limits for residential farming established by the US Department of Energy at the Fernald, OH, uranium plant, which handled and stored the same concentrated Manhattan Project-era wastes; the geographical distribution of the exceedances are consistent with water and radon gas releases from a landfill and related sites used to store and dispose of legacy uranium wastes; and offsite soil and house dust samples proximal to the landfill showed distinctive secular disequilibrium among uranium and its progeny indicative of uranium ore processing wastes. The secular disequilibrium of uranium progeny in the environment provides an important method for distinguishing natural uranium from industrial uranium wastes. In this study, the detection of unsupported (210)Pb beyond expected atmospheric deposition rates is examined as a possible indicator of excessive radon emissions from buried uranium and radium-containing wastes.

    2007-01-01

    Why is it that after centuries of concerted efforts to eliminate it, and decades of unprecedented economic growth that should have accomplished it, poverty not only is still with us but actually is increasing? Starting with a passage in the Old Testament, the source of moral behavior for believers of Judaism, Christianity, and Islam, this author argues that the postulation of the labor theory of value and scarcity by Adam Smith, and accepted as part of the basic framework of the discipline of economics, has prevented us from formulating public policies that would enable us to implement the way the God of the Abrahamic faiths intended the poor to be cared for. Substituting modifications in economic theory proposed originally by Louis Kelso, a model acknowledging the independent contribution of capital in the productive process is proposed that would enable us to formulate policies for the production and distribution of wealth and that would make the scourge of human poverty a bad dream of the past.

    2015-06-01

    Full Text Available The dengue virus (DENV, which is frequently involved in large epidemics, and the yellow fever virus (YFV, which is responsible for sporadic sylvatic outbreaks, are considered the most important flaviviruses circulating in Brazil. Because of that, laboratorial diagnosis of acute undifferentiated febrile illness during epidemic periods is frequently directed towards these viruses, which may eventually hinder the detection of other circulating flaviviruses, including the Saint Louis encephalitis virus (SLEV, which is widely dispersed across the Americas. The aim of this study was to conduct a molecular investigation of 11 flaviviruses using 604 serum samples obtained from patients during a large dengue fever outbreak in the state of Mato Grosso (MT between 2011 and 2012. Simultaneously, 3,433 female Culex spp. collected with Nasci aspirators in the city of Cuiabá, MT, in 2013, and allocated to 409 pools containing 1-10 mosquitoes, were also tested by multiplex semi-nested reverse transcription PCR for the same flaviviruses. SLEV was detected in three patients co-infected with DENV-4 from the cities of Cuiabá and Várzea Grande. One of them was a triple co-infection with DENV-1. None of them mentioned recent travel or access to sylvatic/rural regions, indicating that transmission might have occurred within the metropolitan area. Regarding mosquito samples, one pool containing one Culex quinquefasciatus female was positive for SLEV, with a minimum infection rate (MIR of 0.29 per 1000 specimens of this species. Phylogenetic analysis indicates both human and mosquito SLEV cluster, with isolates from genotype V-A obtained from animals in the Amazon region, in the state of Pará. This is the first report of SLEV molecular identification in MT.

  19. Test of the Louis scheme and COARE algorithm for friction velocity in different wind-sea/swell regimes

    Institute of Scientific and Technical Information of China (English)

    2005-01-01

    The Louis scheme and the COARE algorithm (version 3.0) are tested against eddy covariance and inertial dissipation methods for friction velocity estimates in different wind-sea/swell regimes. Atmospheric forcing data, tabulated by Donelan et al. (1997.J Phys Oceanog, 27:2 087~2 099), were collected from a mast on the foredeck ofa SWATH (small water-plane area, twin hull) ship in deep sea off the State of Virginia during the surface wave dynamics experiment. These data are representative of low to moderate wind regimes.The aerodynamic roughness length is determined by using the Charnock relationship. The intercomparison shows that the Louis scheme and the COARE algorithm underestimate the friction velocity by 6% and 3% respectively under pure wind sea conditions, 15% and 13% respectively under cross swell conditions, and 21% and 17% respectively under counter swell conditions. The analysis shows that these underestimations were caused by the method chosen to determine the aerodynamic roughness length because it significantly underestimates the aerodynamic roughness length. It is especially true under the cross swell and counter swell conditions.

    Full Text Available On January 7, 1933, two years before Gershwin’s Porgy and Bess, The Emperor Jones, composed by Louis Gruenberg in 1931, had its world premiere at the Metropolitan Opera of New York. Although Gruenberg’s opera looks like a mere musical adaptation of O’Neill’s acclaimed play, first performed in 1920, some alterations made by the composer allow to question its ambivalent reception by the audience and the critics. Apart from the singular choice of O’Neill’s play and Gruenberg’s special interest in African American music and vocal traditions, this paper analyses the influence of the Harlem Renaissance period and the fantasmatics of race, present in both the play and the opera, albeit exacerbated in the latter through the scopic enjoyment of the body of the black Other.

À partir de ces faits, nous essaierons de montrer comment les sciences du sport et l’anthropologie naissante se mirent ensemble au service de causes aussi discutables que la hiérarchisation raciale et le droit à la colonisation et contribuèrent grandement à la naissance d’une nation américaine mettant le sport au cœur de sa constitution. L’impact des race studies sur les façons de penser le sport ne furent pas, contrairement à ce que s’efforcèrent de faire croire les différents présidents du C.I.O. au cours des décennies suivantes, qu’un simple avatar du mouvement olympique. Enfin, nous verrons l’influence de ce spectacle athlétique interracial en dehors des États-Unis qui a assurément permis d’élaborer une certaine perception de l’altérité et limiter l’insertion des peuples autochtones dans le tissu sportif mondial.In 1904, in St. Louis, the Olympic competitions were lost in the chaos of a World Fair called the Louisiana Purchase Exposition. The Olympic Games could not escape the rise in the racist ideologies of the 20th century and they contributed to the discussing of the athletic merit of the different races. In spite of the universal spirit that was expected to prevail, the Games of St. Louis showed the racial

    Full Text Available O presente artigo busca recuperar o papel de Anatole Louis Garraux na promoção do comércio de livros franceses em São Paulo. Negociante natural de Paris, instalou-se na capital paulistana em 1860, vindo a se tornar o maior livreiro da cidade nas últimas décadas do século. Entre o processo de instalação da Casa Garraux e sua consagração no meio intelectual citadino, descobrimos que foram variados os seus empreendimentos e suas relações com o comércio franco-brasileiro. Todas, porém, situam-se no período de expansão do comércio de bens de consumo importados. Nesse sentido, o problema da circulação do livro será abordado na perspectiva de expansão do capitalismo editorial francês e das condições de consumo de livros existentes na capital.This article approaches some aspects of the bookseller Anatole Louis Garraux and the environment of the French publishing market in São Paulo. A French businessmen that came to this city in 1860, he became its biggest bookseller in the end of 19th century. Between the foundation of Casa Garraux and his recognition by city's intellectuals, we have found out his business had been become diversified in French-Brazilian trade. All of them, however, are located in time of international trade expansion of consumer goods. On this way, book will be approached by the point of view of Publishing Capitalism expansion and the consumption potential observed in the city.

  6. A study of model parameters associated with the urban climate using HCMM data. [analysis of St. Louis, Missouri infrared imagery

    Progress in the study of the intensity of the urban heat island is reported. The intensity of the heat island is commonly defined as the temperature difference between the center of the city and the surrounding suburban and rural regions. The intensity is considered as a function of changes in the season and changes in meteorological conditions in order to derive various parameters which may be used in numerical models for urban climate. Twelve case studies were selected and CCT's were ordered. In situ data was obtained from sixteen stations scattered about the city of St. Louis. Upper-air meteorological data were obtained and the water vapor and the temperature data were processed. Atmospheric transmissivities were computed for each of the case studies.

    Historians of medicine--and even Louis Pasteur's biographers--have paid little attention to his close relationship with the Finnish artist Albert Edelfelt. A new look at Edelfelt's letters to his mother, written in Swedish and never quoted at length in English, reveals important aspects of Pasteur's working habits and personality. By understanding the active collaboration through which this very famous portrait was made, we also discover unnoticed things in the painting itself, gain a new appreciation of its original impact on the French public's image of science, and better understand its enduring influence on the portrayal of medicine in the art and the popular culture of many countries even to the present day.

Scott démontre que les deux auteurs jouent différemment du métissage et de son rapport avec le colonialisme : tandis que Hamelin met en scène des personnages autochtones dévirilisés et en perte d’authenticité, Highway s’appuie sur la notion amérindienne de bispiritualité pour créer des personnages queer qui transcendent les constructions binaires sur lesquelles se base la masculinité hégémonique. Corrie Scott examines the notion of métissage in the representation of Indigenous masculinities in Cowboy by Québécois novelist Louis Hamelin (1992 and in Kiss of the Fur Queen by Cree novelist Tomson Highway (1998. Scott shows the different ways in which the two authors approach the notion of métissage and its relationship with colonialism: while Hamelin depicts hybrid Indigenous characters as less authentic and virile, Highway embraces a queer poetics that questions hegemonic masculinities and gendered colonial stereotypes through hybrid fictional male identities. An intersectional theoretical framework proves essential to the analysis of hegemonic masculinities which function hand in hand with colonialism.

    St. Louis encephalitis virus (SLEV) (Flavivirus) is a reemerging arbovirus in the southern cone of South America. In 2005, an outbreak of SLEV in central Argentina resulted in 47 human cases with 9 deaths. In Argentina, the ecology of SLEV is poorly understood. Because certain birds are the primary amplifiers in North America, we hypothesized that birds amplify SLEV in Argentina as well. We compared avian SLEV seroprevalence in a variety of ecosystems in and around Córdoba city from 2004 (before the epidemic) and 2005 (during the epidemic). We also explored spatial patterns to better understand the local ecology of SLEV transmission. Because West Nile virus (WNV) was also detected in Argentina in 2005, all analyses were also conducted for WNV. A total of 980 birds were sampled for detection of SLEV and WNV neutralizing antibodies. SLEV seroprevalence in birds increased 11-fold from 2004 to 2005. Our study demonstrated that a high proportion (99.3%) of local birds were susceptible to SLEV infection immediately prior to the 2005 outbreak, indicating that the vertebrate host population was primed to amplify SLEV. SLEV was found distributed in a variety of environments throughout the city of Córdoba. However, the force of viral transmission varied among sites. Fine scale differences in populations of vectors and vertebrate hosts would explain this variation. In summary, we showed that in 2005, both SLEV and to a lesser extent WNV circulated in the avian population. Eared Dove, Picui Ground-Dove and Great Kiskadee are strong candidates to amplify SLEV because of their exposure to the pathogen at the population level, and their widespread abundance. For the same reasons, Rufous Hornero may be an important maintenance host for WNV in central Argentina. Competence studies and vector feeding studies are needed to confirm these relationships.

    In the week following Hurricane Katrina, over 3000 patients were evacuated by air from a triage and medical treatment station at the Louis Armstrong New Orleans International Airport. This represents the largest air evacuation in history. Over 24,000 additional evacuees were transported from the airport to shelters. Disaster Medical Assistance Teams (DMATs) from several US states were deployed to the Louis Armstrong New Orleans International Airport to provide medical care to those evacuated from New Orleans. Despite warning from the US National Weather Service of catastrophic damage to New Orleans, adequate medical staffing was not attained at the airport triage station until 6 days after the hurricane struck. Organizational lapses, including inadequate medical and operational planning, understaffing of medical personnel, and failure to utilize Incident Command System, diminished the effectiveness of the Hurricane Katrina New Orleans Medical Operation.

    Full Text Available The island of Saint-Louis of Senegal was awarded the status of world heritage site by UNESCO in 2000 as an “outstanding example” of urban heritage. This island city comes with a unique heritage: development planning that combines a strong historical French influence with a gridiron urban morphology and building typology. The island must be interpreted within its total territorial context that includes both the island of Sor (on the mainland and La Langue de la Barberie, a sandy barrier that separates the mouth of the river from the sea. The city of Saint-Louis itself has grown enormously and haphazardly from the latter part of the 20th century: it is now the fourth most populous city in Senegal. At present, the city is undergoing a serious period of decline and recession due, in part, to the overriding influence of the capital, Dakar, and the centralized political forces in the country. This article looks at the key morphological and functional reasons behind the development and evolution of the island of Saint-Louis and that persist in the present context, with justifications for the deep-rooted heritage values that maintain its prestige as a World Heritage Site.

    Full Text Available On 8th May, 1731, an ordinance of Louis XV, King of France, imposed separation between the production and sale activities of the weavers of ‘gold, silver and silk’ at the famous Lyon Manufactory in which hundreds of families worked. The ordinance plunged into despair the workers (maîtres ouvriers who, up till then, for centuries, had been allowed to sell their goods freely and were now in danger of being reduced to poverty by a handful of traffickers who knew nothing about their extremely sophisticated, skilful trade, but would be enabled to capitalize on their work. They therefore addressed two petitions (the first in 1731 and the second in 1732 to the King and Monseigneur Poulletier, the King’s Superintendent and the Manufactory’s Overseer, asking for the abrogation of the ordinance and a revision of the Manufactory’s regulations. The interesting aspect of these two petitions is that they show the workers’ consciousness of their rights; indeed, their denunciation of these abuses foretells, a century before, the two important revolts of the canuts (as the Lyon textile workers were known which were to break out in 1831 and 1834.

    2015-01-01

    It has been suggested that Robert Louis Stevenson's masterpiece Strange Case of Dr. Jekyll and Mr. Hyde derived inspiration from the real-life tragedy of the final days of Connecticut dentist Horace Wells, innovator of the clinical use of the anesthetic properties of nitrous oxide. We examined Stevenson's letters, biographies, and other references in the literature, press, and online to determine whether any factual basis exists for Stevenson to be aware of Wells' life, and also if it played any role in creating the novel's plot. Stevenson was born in Scotland, several years after Wells had committed suicide in New York. Wells' life and death received widespread coverage in the northeastern United States, but there is no evidence that it was printed in newspapers or periodicals in England or Scotland. On the other hand, novelists of the period, psychologists, and the lay public were quite interested in the concept of split personalities and the dual nature of man, so these may have been natural substrates for the novel. There is evidence that Stevenson dreamt about episodes similar to those depicted in his novel. All claims to any relationship between Wells and the novel come from the United States, and none of them are backed by evidence. In the absence of evidence supporting a relationship between the behavior exhibited by Wells during his final days and any inspiration that Stevenson might have derived from it, we conclude that there is insufficient evidence to suggest any relationship between them.

    Full Text Available Saint Louis encephalitis virus caused an outbreak of febrile illness and encephalitis cases in Córdoba, Argentina, in 2005. During this outbreak, the strain CbaAr-4005 was isolated from Culex quinquefasciatus mosquitoes. We hypothesised that this epidemic variant would be more virulent in a mouse model than two other non-epidemic strains (78V-6507 and CorAn-9275 isolated under different epidemiological conditions. To test this hypothesis, we performed a biological characterisation in a murine model, including mortality, morbidity and infection percentages and lethal infection indices using the three strains. Mice were separated into age groups (7, 10 and 21-day-old mice and analysed after infection. The strain CbaAr-4005 was the most infective and lethal of the three variants, whereas the other two strains exhibited a decreasing mortality percentage with increasing animal age. The strain CbaAr-4005 produced the highest morbidity percentages and no significant differences among age groups were observed. The epidemic strain caused signs of illness in all inoculated animals and showed narrower ranges from the onset of symptoms than the other strains. CbaAr-4005 was the most virulent for Swiss albino mice. Our results highlight the importance of performing biological characterisations of arbovirus strains likely to be responsible for emerging or reemerging human diseases.

    Gentilcore, David

    2016-01-01

    This article explores the extent to which the bacterial concept of disease acted as an obstacle to the understanding of deficiency diseases, by focusing on explorations into the cause of pellagra in the early twentieth century. In 1900, pellagra had been epidemic in Italy for 150 years and was soon to become so in the United States, yet the responses of medical investigators differed substantially. To account for these, the article reconstructs the sharply contrasting reactions to a provocative theory proposed by Louis Sambon. Applying a tropical diseases approach to pellagra, Sambon argued that pellagra had nothing at all to do with maize consumption, as the Italians had long thought, but was caused by the bite of a parasite-carrying insect. Italian pellagrologists, involved in a dogmatic quest for a toxin in maize, and with pellagra rates there on the decline, marginalized the Sambon hypothesis. By contrast, in the United States, with pellagra on the rise, the dominant infectious paradigm put Sambon center stage, his proposed etiology shaping the earliest American investigations. When the deficiency disease concept gained currency in 1913, the relatively closed world of Italian pellagrology was wrong-footed, while the more open-ended U.S. community was better able to follow up the new lead. The article discusses what these shifts and the resulting controversies reveal about the medical contexts. The actor-centered approach, with reaction to Sambon's intervention as a kind of test-case, is the key to understanding these controversies and why they mattered.

    Louis Nico Marie (L. N. M.) Duijsens (Duysens) was one of the giants in the biophysics of photosynthesis. His PhD thesis "Transfer of Excitation Energy in Photosynthesis" (Duysens, 1952) is a classic; he introduced light-induced absorption difference spectroscopy to photosynthesis research and proved the existence of reaction centers, introducing advanced methods from physics to understand biological processes. Further, it is his 1959-1961 seminal work, with Jan Amesz, that provided evidence for the existence of the series scheme for the two light reactions in oxygenic photosynthesis. In one word, he was one of the master biophysicists of the 20th century-who provided direct measurements on many key intermediates, and made us understand the intricacies of photosynthesis with a simplicity that no one else ever did. We present here our personal perspective of the scientist that Lou Duysens was. For an earlier perspective, see van Grondelle and van Gorkom (Photosynth Res 120: 3-7, 2014). PMID:27039907

This technical approach is a powerful tool for combining important information for a better comprehension of the floods and the characterization of surface qualities on the estuary. By way of a multi-temporal approach, the study team established the qualitative and quantitative impact of floods on the various geographical objects, a detailed cartography of the land use and the surfaces flooded in 1998 and 1999. The study undertaken in Saint Louis made it possible to consider surfaces flooded in 1999, and to understand the extent of these floods compared to those of 1998. The constitution of a tool of decision-making aid makes it possible to have information relating to the extent of the flood, the scope of flooded surfaces and to detect the more exposed zones in order to establish a hierarchical map according to the percentage of exposure to the risk of the geographical objects affected by the floods (populations, road infrastructures and tracks, medical and social infrastructures and perimeters of cultures (agriculture.

    Full Text Available The article focuses on the presence and the absence of windows, and specifically windows with shutters, car windows and rear-view mirrors in the novels by Haitian writer Louis-Philippe Dalembert. In his work, we can identify three tendencies. First of all, windows with shutters allow the passage from childhood to adulthood. Secondly, the absence of openings projects the character in heterotopias, which cause a language breakdown. Thirdly, the use of literary windows is linked with vagabondage and pays-temps. An image of the landscape is selected through a frame and we have the perception of a fragmentary vision. According to Dalembert, this world vision becomes a narrative element and a creative technique. This partial image which emerges from the symbolic space of the window allows us to talk about the childhood of the narrator from different perspectives: we can identify a geographical and temporal landscape (pays-temps thanks to a reflection on the surface of the window and the possibility of remembering and imaging the past. Fiction is able to complete omissions, gaps, lapses.

Cette tradition de luxuriance se traduit à l’âge d'or bourguignon par une efflorescence de couleurs sur les édifices qui durera jusqu’à la prise de Lille par Louis XIV en 1667. Les portes « espagnoles » affichent leurs briques émaillées de couleur. L’hospice Comtesse placarde son retable de pierres peintes sur sa façade d’entrée. La Vieille Bourse colore ses façades au modèle d’un cabinet d’ébénisterie avec ses incrustations de pierres nacrées et de brique luisantes comme les écailles de tortue. Le style franco‑lillois transmettra ce goût pour la couleur à travers la reconstitution du centre ville au xviie siècle, ce dont témoigne le plan-relief de 1743.

Se sostendrá que la lectura de Maquiavelo sobredetermina la intervención teórica de Althusser incorporando ‘nuevos’ temas y reactualizando ‘viejos’ interrogantes del althusserianismo. De modo que una lectura como esta permitiría recuperar de una manera específica cierto legado del autor. En segundo lugar, por medio del tratamiento de la problemática del comienzo en política en sus condiciones de imposibilidad -entre la eterna repetición de lo mismo y la absoluta contingencia por venir-, se señalará que lo que el autor encuentra frente a Maquiavelo es la posibilidad de una expansión del potencial de sentido de la política frente a quienes pretenden reducirla en su concepto y sus efectos. Producto de este análisis se señalará hasta qué punto la interrogación de Althusser por la política puede ser inscripta en un horizonte teórico posfundacional.

    I. The Caste System and the Hierar-chy:Dumont and his Indian Study As one of the most important anthropologists in 20th century, Louis Dumont, on one hand, suc-cessfully introduced anthropological theory and methodology to Indian Studies,on the other hand, he contributed a lot to anthropology through his In-dian studies. He applied structuralism and ideology in his fieldwork and ethnography,and refocused at-tention on comparative studies based on local con-cepts, categories and values. In his Homo Hierar-chicus,he applied his mentor Marcel Mauss’ idea of totality,and emphasized that : “it is only in rela-tion to the totality thus reconstructed that the ideol-ogy takes on its true sociological significance.”This book is also remarked on as one of the best studies for understanding other societies based on this society’s social theory. Another book by him, Essays on Individualism,is praised as presenting an anthropological way of rethinking the locality of western civilization and its ideology,instead of re-garding it as universal. Based on the comparative study of“western” and “eastern” civilizations, he proposes: “our problem is: how can we build a bridge between our modern ideology that separates values and ‘fact’ and other ideologies that embed values in their world view?”His most famous and important concept is“hierarchy”,which he believes is the key to under-standing the Indian caste system and Indian socie-ty. He emphasizes that hierarchy cannot be ex-plained by the western idea of class or social strati-fication. He defines hierarchy as a concept derived from traditional Hindu theory,as “the principle by which the elements of a whole are ranked in rela-tion to the whole.” Hierarchy,with the caste sys-tem as its social form, is underlined by the Hindu opposition between pure and impure. Dumont high-lights this opposition as a “Synthetic a priori”op-position which follow such a principle:“the whole is founded on the

    Dahl-Jensen, Dorthe

    2014-05-01

    Greenland ice cores contain very highly resolved climate records reaching 128.000 years back in time. When dated and matched they tell tales on very abrupt climate changes especially during the glacial period demonstrating that internal energy exchange in the climate system can cause dramatic and fast changes with no external forcing. When the water stable isotope records from the six deep ice cores are compared they inform on both temperature changes and elevation changes of the Greenland ice sheet during glacial and interglacial periods. The temperature and elevation changes during the last 128.000 years are presented and the knowledge gained is used to discuss how this knowledge can be used to predict the future volume change of the Greenland ice sheet. This knowledge can improve estimates of future sea level rise predictions and is a demonstration of how knowledge from the past can be used to predict the future.

  18. The political and economic impacts of writing across the curriculum in chemistry at the University of Missouri-St. Louis

    Science.gov (United States)

    Klein, William Dixon

    Writing Across the Curriculum at most institutions is a web of local knowledges and techniques "situated" within the historical and immediate contexts of academic departments, disciplines, and disciplinary cultures. Because of political and economic tensions existing within colleges and universities, and within academic disciplines themselves, WAC can become a "contact zone," where individuals and institutional structures struggle for power, influence, and in some cases, survival. This dissertation uses the work of Anthony Giddens and Pierre Bourdieu to examine such a struggle as it occurred at the University of Missouri-St. Louis in the early 1980s. A WAC program was initiated there, but eventually failed as a result of political and economic influences. In the time since that failure, a growing emphasis on teaching and learning has helped create new potential for WAC at UMSL. Yet, to make it viable, WAC proponents there must recognize existing realities, attitudes, and conventions within each discipline or department, and develop new methods and approaches to writing and teaching that are relevant to that discipline or department. This examination then focuses on writing in chemistry to discover the realities, attitudes, and conventions used in teaching and learning writing at the undergraduate level. Standards for content acquisition are gathered from ACS accreditation requirements, and from a study of educators and practitioners from a variety of professions. A study of Chemistry students in an NSF-funded educational program suggests that science students may learn as much or more about disciplinary discourse from sources other than the traditional writing course. Interaction with the literature and with graduate students, professors, and professionals may teach students more about disciplinary discourse conventions than a composition-trained specialist might accomplish in a writing course. Still, the writing course can be useful. These findings suggest that

    Directory of Open Access Journals (Sweden)

    Kristin D. Wilson

    2016-03-01

    Full Text Available In the early 1990s, St. Louis County had multiple foodservice worker-related hepatitis A outbreaks uncontrolled by standard outbreak interventions. Restaurant interest groups and the general public applied political pressure to local public health officials for more stringent interventions, including a mandatory vaccination policy. Local health departments can enact mandatory vaccination policies, but this has rarely been done. The study objectives were to describe the approach used to pass a mandatory vaccination policy at the local jurisdiction level and illustrate the outcome from this ordinance 15 years later. A case study design was used. In-depth, semi-structured interviews using guided questions were conducted in spring, 2015, with six key informants who had direct knowledge of the mandatory vaccination policy process. Meeting minutes and/or reports were also analyzed. A Poisson distribution analysis was used to calculate the rate of outbreaks before and after mandatory vaccination policy implementation. The policy appears to have reduced the number of hepatitis A outbreaks, lowering the morbidity and economic burden in St. Louis County. The lessons learned by local public health officials in passing a mandatory hepatitis A vaccination policy are important and relevant in today’s environment. The experience and lessons learned may assist other local health departments when faced with the potential need for mandatory policies for any vaccine preventable disease.

  20. When did Louis Pasteur present his memoir on the discovery of molecular chirality to the Académie des sciences? Analysis of a discrepancy.

    Science.gov (United States)

    Gal, Joseph

    2008-11-01

    Louis Pasteur presented his historic memoir on the discovery of molecular chirality to the Académie des sciences in Paris on May 22nd, 1848. The literature, however, nearly completely ignores this date, widely claiming instead May 15th, 1848, which first surfaced in 1922 in Pasteur's collected works edited by his grandson Louis Pasteur Vallery-Radot. On May 21st, 1848, i.e., one day before Pasteur's presentation in Paris, his mother died in Arbois, eastern France. Informed at an unknown point in time that she was "very ill," Pasteur left for Arbois only after his presentation. Biographies of Pasteur by his son-in-law René Vallery-Radot or the grandson, and Pasteur's collected correspondence edited by the grandson are incomprehensibly laconic or silent about the historic presentation. While no definite conclusions are possible, the evidence strongly suggests a deliberate alteration of the record by the biographer relatives, presumably for fear of adverse public judgment of Pasteur for a real or perceived insensitivity to a grave family medical emergency. Such fear would have been in accord with their hagiographic portrayal of Pasteur, and the findings raise questions concerning the extent of their zeal in protecting his "demigod" image. Universal recognition of the true date of Pasteur's announcement of molecular chirality is long overdue.

    2015-05-01

    Following the introduction of West Nile virus into California during the summer of 2003, public health and vector control programs expanded surveillance efforts and were in need of diagnostics capable of rapid, sensitive, and specific detection of arbovirus infections of mosquitoes to inform decision support for intervention. Development of a multiplex TaqMan or real-time semiquantitative reverse transcription polymerase chain reaction (RT-PCR) assay in which three virus specific primer-probe sets were used in the same reaction is described herein for the detection of western equine encephalomyelitis, St. Louis encephalitis and West Nile viral RNA. Laboratory validation and field data from 10 transmission seasons are reported. The comparative sensitivity and specificity of this multiplex assay to singleplex RT-PCR as well as an antigen detection (rapid analyte measurement platform) and standard plaque assays indicate this assay to be rapid and useful in providing mosquito infection data to estimate outbreak risk.

    Full Text Available In addition to the superficial visual similarities between the architectural theories of the Silesian-born, seventeenth-century Dutch mathematician Nicolaus Goldmann and the early nineteenth-century French architect Jean-Nicolas-Louis Durand, there is a more profound interconnection: their use of the grid. This article evaluates the relation between the two theories and argues how Durand could have been influenced by Goldmann’s writings. It turns out to be more than likely that the two were linked by Durand´s German pupils who brought the tradition of German eighteenth-century architectural theory with them. This corpus was nourished by Leonhard Christoph Sturm´s ‘Goldmannic’ architecture.

Inoltre, questi due esempi di auto-socio-analisi possono essere interpretati come contributi a un dibattito pubblico che in Francia e non solo si confronta con il valore politico di identità sociali sempre più complesse e con dinamiche elettorali che dagli anni Sessanta a oggi hanno sciolto il legame tra forze politiche della sinistra e classi sociali più svantaggiate.

    Desertification is regarded as one of the major global environmental problems of the 21st century. The African sub-Sahara is often quoted as the most seriously affected region with a significant loss of biological and economic productivity of the land due to climate characteristics and fluctuations, unsustainable land uses, overgrazing and inappropriate agricultural practices. Due to its complexity, dynamism and extent, desertification is complicated to check and assess. The absence of an agreed methodology for the identification of affected areas is a critical point in desertification monitoring and assessment. An integrated approach which uses both qualitative and quantitative measures is crucial to reach the aim of sustainable resource use and has to be reflected in application of sets of indicators. The selection of appropriate indicators and their integration and interpretation should be conducted by the objectives to be achieved and the questions to be answered. This study, carried out within the FP7-ENV-2010 CLUVA project (Climate change and Urban Vulnerability in Africa), aimed to assess the sensitivity to desertification in peri-urban areas of both Ouagadougou (Burkina Faso) and Saint Louis (Senegal) cities. The approach was based on the implementation and adaptation to the local conditions of the modeling methodology developed within the MEDALUS project (Mediterranean Desertification And Land Use). The model is characterized by a multi-factor approach based on the assessment of both environmental quality indicators (vegetation, soil, climate) and anthropogenic factors (land management). All local data, arranged in a GIS environment, allowed the generation of maps identifying Environmentally Sensitive Areas (ESAs) and an Index of Environmentally Sensitive Areas (ESAI). Changes and integrations to the original methodology have been set taking into account the environmental and social features of the whole sub-Saharan west Africa in order to allow the use of

    In this study, we explored the spatial and temporal patterns of land cover and land use (LCLU) and population change dynamics in the St. Louis Metropolitan Statistical Area. The goal of this paper was to quantify the drivers of LCLU using long-term Landsat data from 1972 to 2010. First, we produced LCLU maps by using Landsat images from 1972, 1982, 1990, 2000, and 2010. Next, tract level population data of 1970, 1980, 1990, 2000, and 2010 were converted to 1-km square grid cells. Then, the LCLU maps were integrated with basic grid cell data to represent the proportion of each land cover category within a grid cell area. Finally, the proportional land cover maps and population census data were combined to investigate the relationship between land cover and population change based on grid cells using Pearson's correlation coefficient, ordinary least square (OLS), and local level geographically weighted regression (GWR). Land cover changes in terms of the percentage of area affected and rates of change were compared with population census data with a focus on the analysis of the spatial-temporal dynamics of urban growth patterns. The correlation coefficients of land cover categories and population changes were calculated for two decadal intervals between 1970 and 2010. Our results showed a causal relationship between LCLU changes and population dynamics over the last 40 years. Urban sprawl was positively correlated with population change. However, the relationship was not linear over space and time. Spatial heterogeneity and variations in the relationship demonstrate that urban sprawl was positively correlated with population changes in suburban area and negatively correlated in urban core and inner suburban area of the St. Louis Metropolitan Statistical Area. These results suggest that the imagery reflects processes of urban growth, inner-city decline, population migration, and social spatial inequality. The implications provide guidance for sustainable urban

    ABSTRACT:Cement channel linings in an urban stream in St. Louis, Missouri increase event water contributions during flooding, shorten transport times, and magnify geochemical variability on both short and seasonal timescales due to disruption of hyporheic flowpaths. Detailed analyses of water iso-topes, major and trace elements, and in situ water quality data for an individual flood event reveal that baseflow contributions rise by 8%only 320 m downstream of the point where this particular channel changes from cement-lined to unlined. However, additional hydrograph separations indicate baseflow contributions are variable and can be much higher (average baseflow increase is 16%). Stream elec-trical conductivity (EC) and solute concentrations in the lined reach were up to 25%lower during peak flow than in the unlined channel, indicating a greater event flow fraction. In contrast, during low flow, stream EC and solute concentrations in the lined reach were up to 30%higher due to the restricted in-flow of more dilute groundwater. Over longer timescales, EC, solute concentrations, turbidity, and bacterial loads decrease downstream signifying increasing contributions of dilute baseflow. The de-creased connectivity of surface waters and groundwaters along the hyporheic zone in lined channels increases the hydrologic and geochemical variability of urban streams.

    Nearly a decade after discovering molecular chirality in 1848, Louis Pasteur changed research direction and began investigating fermentations. Conflicting explanations have been given for this switch to microbiology, but the evidence strongly suggests that Pasteur's appointment in 1854 to the University of Lille--an agricultural-industrial region where fermentation-based manufacturing was of great importance--and an appeal for help in 1856 by a local manufacturer experiencing problems in his beetroot-fermentation-based alcohol production played a significant role. Thus began, in late 1856, Pasteur's pioneering studies of lactic and alcoholic fermentations. In 1857, reportedly as a result of a laboratory mishap, he found that in incubations of ammonium (+/-)-tartrate with unidentified microorganisms (+)-tartaric acid was consumed with considerable preference over (-)-tartaric acid. In 1860, he demonstrated a similar enantioselectivity in the metabolism of tartaric acid by Penicillium glaucum, a common mold. Chance likely played a significant role both in Pasteur's shift to microbiology and his discovery of enantioselective tartrate fermentations, but he rejected pure serendipity as a significant factor in experimental science and in his own career. Pasteur's milestone discovery of biological enantioselectivity began the process that in the long run established the fundamental importance of molecular chirality in biology.

    Full Text Available Although throughout the middle-ages Jews used to live in urban environment more than non-Jews, urbanization process in the 19th century was as critical to Jewish modern history as in other cases. Modernization, in all aspects, had a deep impact on Jewish demography, socio-economic life and self understanding. On the same time Jews were immigrating by the millions to the “new world” (mainly to the United States, a small current of Jews was heading to Palestine (Eretz Israel if to use their specific term. As opposed to a common understanding of Zionism, the future city and the neo-urbanization of the Jews – and not only the new villages (Moshavot, Kibbutzim, Moshavim – was a main Zionist goal. This article describes one of the first comprehensive observations of these issues, as seen from the eyes of Louis Miller, himself a Jewish immigrant that settled in the outmost city of the modern world: New York. In 1911 he paid a visit to the one-year-old Tel Aviv, and managed to see in this new modest garden-city the cradle of the Zionist revolution. Not less important: Miller understood as early as 1911, the crucial role Jewish settlements in Palestine would have in the crystallization of modern Jewish peoplehood. Tel Aviv took major part in this development. It still does.

    An understanding of urban aquatic environments as mosquito larval habitats is necessary to prioritize sites for surveillance and control of arbovirus vectors in urban areas. Natural and artificial water bodies at ground level that may be larval mosquito habitats in Córdoba city, Argentina were surveyed. Data on the characteristics of aquatic sites and the presence and abundance of mosquito larvae and pupae were collected in the summer of 2006, coinciding with the first report of human WNV and following an outbreak of St. Louis encephalitis in 2005. Eight species in the genera Aedes, Culex, and Mansonia were identified. At 64.2% (34 of 53) of the sites, only one species was collected, while 3.8% (2 of 53) had three associated species, the highest richness found per site. Culex quinquefasciatus represented over 99% (out of 32,729) of the specimens. It was also the most widely distributed and detected under diverse habitat conditions. Although puddles and semi-permanent pools harbored a greater number of species, drainages and channels may be more relevant as risk factors from an epidemiological point of view because they showed the highest larval densities, mainly of Cx. quinquefasciatus (vector of SLE and WNV). Also, higher densities of this species were associated with stormwater runoff and sewage water, thus water management systems should be targeted and closely monitored for mosquito control purposes.

    Full Text Available Introduction Saint Louis encephalitis virus (SLEV primarily occurs in the Americas and produces disease predominantly in humans. This study investigated the serological presence of SLEV in nonhuman primates and horses from southern Brazil. Methods From June 2004 to December 2005, sera from 133 monkeys (Alouatta caraya, n=43; Sapajus nigritus, n=64; Sapajus cay, n=26 trap-captured at the Paraná River basin region and 23 blood samples from farm horses were obtained and used for the serological detection of a panel of 19 arboviruses. All samples were analyzed in a hemagglutination inhibition (HI assay; positive monkey samples were confirmed in a mouse neutralization test (MNT. Additionally, all blood samples were inoculated into C6/36 cell culture for viral isolation. Results Positive seroreactivity was only observed for SLEV. A prevalence of SLEV antibodies in sera was detected in Alouatta caraya (11.6%; 5/43, Sapajus nigritus (12.5%; 8/64, and S. cay (30.8%; 8/26 monkeys with the HI assay. Of the monkeys, 2.3% (1/42 of A. caraya, 6.3% 94/64 of S. nigritus, and 15.4% (4/26 of S. cay were positive for SLEV in the MNT. Additionally, SLEV antibodies were detected by HI in 39.1% (9/23 of the horses evaluated in this study. Arboviruses were not isolated from any blood sample. Conclusions These results confirmed the presence of SLEV in nonhuman primates and horses from southern Brazil. These findings most likely represent the first detection of this virus in nonhuman primates beyond the Amazon region. The detection of SLEV in animals within a geographical region distant from the Amazon basin suggests that there may be widespread and undiagnosed dissemination of this disease in Brazil.

    Meredith, Philip

    2016-04-01

    Earthquake ruptures and volcanic eruptions are the most dramatic manifestations of the dynamic failure of a critically stressed crust. However, these are actually very rare events in both space and time; and most of the crust spends most of its time in a highly stressed but subcritical state. Under upper crustal conditions most rocks accommodate applied stresses in a brittle manner through cracking, fracturing and faulting. Cracks can grow at all scales from the grain scale to the crustal scale, and under different stress regimes. Under tensile stresses, single, long cracks tend to grow at the expense of shorter ones; while under all-round compressive, multiple microcracks tend to coalesce to form macroscopic fractures or faults. Deformation in the crust also occurs over a wide range of strain rates, from the very slow rates associated with tectonic loading up to the very fast rates occurring during earthquake rupture. It is now well-established that reactions between chemically-active pore fluids and the rock matrix can lead to time-dependent, subcritical crack propagation and failure in rocks. In turn, this can allow them to deform and fail over extended periods of time at stresses well below their short-term strength, and even at constant stress; a process known as brittle creep. Such cracking at constant stress eventually leads to accelerated deformation and critical, dynamic failure. However, in the period between sequential dynamic failure events, fractures can become subject to chemically-enhanced time-dependent strength recovery processes such as healing or the growth of mineral veins. We show that such strengthening can be much faster than previously suggested and can occur over geologically very short time-spans. These observations of ultra-slow cracking and ultra-fast healing have profound implications for the evolution and dynamics of the Earth's crust. To obtain a complete understanding of crustal dynamics we require a detailed knowledge of all these

    This article aims to investigate the shaping of knowledge and discourse on ginseng, especially among physicians and botanists, since its introduction to France from the 17th century until the early 18th century. In France, knowledge on herbal medicine, including that of ginseng, was shaped under the influence of the modern state's policy and institution: mercantilism and the Académie royale des sciences. The knowledge of herbal medicine developed as an important part of the mercantilist policy supported systematically by the Académie. The East Asian ginseng, renowned as a panacea, was first introduced into France in the 17th century, initially in a roundabout way through transportation and English and Dutch publications of travel tales from various foreign countries. The publication activity was mainly conducted by Thévenot company with the intention to meet the needs of French mercantilism promoted by Colbert. It also implied interests on medicine in order to bolster the people's health. The Thévenot company's activity thus offered vital information on plants and herbs abroad, one of which was ginseng. Furthermore, with Louis XIV's dispatching of the Jesuit missionaries to East Asia, the Frenchmen were able to directly gather information on ginseng. These information became a basis for research of the Académie. In the Académie, founded in 1666 by Colbert, the king's physicians and botanists systematically and collectively studied on exotic plants and medical herbs including ginseng. They were also key figures of the Jardin du Roi. These institutions bore a striking contrast to the faculty of medicine at the University of Paris which has been a center of the traditional Galenic medicine.

    Full Text Available From 1804 to 1809, the slaveholding Napoleonic regime of General Jean-Louis Ferrand attempted to erase the gains of the era of French Republican emancipation (1793-1802 by re-enslaving thousands of individuals in Santo Domingo (modern Dominican Republic. This article examines the aims and methods of the Ferrand regime, situating it within the contexts of the birth of independent Haiti and the resurgence of institutionalized racism and slavery in the French world. Using governmental correspondence, notarial acts, and other sources, I argue that those targeted by Ferrand’s racist laws and efforts to re-impose slavery devised innovative means of carving out their own versions of freedom. The article centers on the ways in which “slaves” and colonial officials negotiated the meanings of slavery in a context in which the institution’s legality was unclear.

    马克思主义的人道主义解释涉及的不仅仅是一个普通概念,而是直接关系到马克思主义生死攸关的命运。作为马克思主义者,阿尔都塞对此作出了自卫反击,他提出“认识论断裂”策略,断定已经被误解为人道主义的青年马克思思想并不属于马克思主义,以保卫马克思主义的纯洁性。%Humanitarian interpretation of Marxism is not just a general concept involved, it is directly related to the life and death fate of Marxism. As a Marxist, Louis Althusser made a self-defense response that posed“epistemological rupture” strategy and concluded that the thought which had been misinterpreted as a humanitarian ideology of the young Marx did not belong to Marxism,to defend the purity of Marxism. This paper discussed the “epistemological break” without prerequisite.

    问题结构是指历史理论的一系列预设与核心概念,它决定了历史理论可能的反思范围和限度。《路易·波拿巴的雾月十八日》是一本重要的历史学著作。在这本著作中,马克思建构出“历史形势”这个独特的问题结构,营造出历史人物活动的理论框架。在历史形势的问题结构中,个人的偶然性和能动性得到严肃的考虑,经济因素和意识形态因素获得了新的理论意义。这表明马克思开创了一种新的历史理论形态。%"Problematics" is the relativey premise and core concept of history theory, which determines the reflection range and limits. " The Eighteenth Brumaire of Louis Bonaparte" is an important historic work, in which Marx formed a special concept of "historical situation" and the theoretical framework of personal activities of past people. In the problematics of the "historical situation" , the occasionality and initiativeness of individual are seriously considered and economic factors and ideological factors have a new theoretical meaning, which proves that Marx created a new theory form.

    The topology, magnitude, and sediment transport capabilities of large-scale turbulence generated over alluvial sand dunes is influential in creating and maintaining dune morphology and in dominating both the flow field and the transport of suspended sediment above dune-covered beds. Combined measurements by means of an acoustic Doppler current profiler (ADCP) and a multibeam echo sounder (MBES) were made in order to examine flow over a series of sand dunes in the Missouri River, near St. Louis, MO, USA in October 2007. The bed topography of the Missouri River was mapped using a RESON 7125 MBES immediately before the ADCP data collection. Time series of velocity and acoustic backscatter were measured using a down-looking 1200 kHz ADCP while anchored at two locations in the dune field. The ADCP used in this study has a sampling rate of 2-3 Hz with 20-25 cm bin sizes. Two time series were collected having durations of 712 and 589 seconds at one location, while the third time series, collected about 4 meters upstream, was 2,270 seconds in duration. Measured streamwise velocities ranged from 0.1 to 2.7 ms-1 for all three stationary time series. Sediment concentration profiles were obtained at the same two locations as the stationary ADCP data using a P-61 sediment sampler and were compared to ADCP acoustic backscatter. Characteristics of turbulent flow structures in a sand bed river are presented. This paper presents data that can be used to investigate the issue of obtaining reliable estimates of turbulence parameters with an ADCP. The analyses will include mean velocity profiles, turbulence intensities, Reynolds shear stresses, quadrant analysis, power spectra, cross-correlation, and frequency analysis. Semi-periodic patterns were observed in each time series, characterized by periods of elevated acoustic backscatter with positive vertical velocities, followed by reduced acoustic backscatter with negative vertical velocities.

    17世纪,葡萄牙国力日渐衰败,令其无法再从经济上支持传教士的东方拓展之旅,这不仅让罗马教廷颇为不满,而且让欧洲新崛起的法国看到了一个取而代之的机会。当时法国遇到的障碍主要有两个,一是葡萄牙所拥有的保教权;二是罗马教廷所要求的宣誓问题。但是,法国政治、科学和宗教的发展需求,加之暹罗使团的突然来访,让路易十四最终决定派遣有皇家科学院通讯院士之称的耶稣会士跟随暹罗使团前往东方。这些耶稣会士便是在中法交流史上赫赫有名的"皇家数学家"。%In the seventeenth century,the power of the Portuguese empire started to decline,making it virtually impossible to support the Jesuits for their exploration of the East financially.This left Roman Curia rather unhappy and meanwhile gave the rising French an opportunity to take over.Having said that,the French also faced two obstacles:the Portuguese monopoly of Patronage in the Far East since the 17th century and the oath of allegiance as required by the Roman Curia.However,driven by the rapid advancement in politics,science and religion,coupled with the unexpected visit of the Siamese mission,the French king Louis XIV eventually made the decision to dispatch the Jesuits to accompany the Siamese mission on their expedition to the East.This group of the Jesuits is famously known as the King's Mathematicians in the exchanges between France and China.

    Louis Kossuth,a leader of the Hungarian Revolution in 1848,had been regarded by Americans of his era as a champion of liberty like George Washington.However,when he visited the United States from Dec.1851 to July 1852,in order to win financial,material,and moral support of Americans and to push American government to interfere in Hungarian affairs,he intentionally evaded the issue of American slavery and declared that he would not meddle with America's "omestic affairs" He kept silent on the sensitive political issue of slavery but gave fulsome praises to American liberty which aroused the anger of the abolitionists and African Americans.The Kossuth's case had highlighted the paradox of freedom and slavery and had promoted some Americans to scrutiny the deep contradictions between them.%路易斯·科苏特是1848年匈牙利独立革命的领袖,被那个时代的美国人视为华盛顿式的自由战士。然而,他于1851年12月至1852年7月访问美国期间,为了争取美国的财政、物资和道义支持以及美国对匈牙利事务的干预,故意回避美国的奴隶制问题,宣布不干预美国的"国内问题"。他在美国奴隶制问题上保持沉默,对美国的"自由"制度极尽溢美之词,引起了废奴主义者和非裔美国人的愤怒。科苏特在美国奴隶制问题上的立场以及美国人对于他访美的反应,凸显了美国自由与奴隶制之间的悖论,促进了美国人对二者之间的矛盾的审视。

    Full Text Available This paper reports the isolation of St. Louis encephalitis virus (SLEV from a febrile human case suspected to be dengue, in São Pedro, São Paulo State. A MAC-ELISA done on the patient's acute and convalescent sera was inconclusive and hemagglutination inhibition test detected IgG antibody for flaviviruses. An indirect immunofluorescent assay done on the C6/36 cell culture inoculated with the acute serum was positive for flaviviruses but negative when tested with dengue monoclonal antibodies. RNA extracted from the infected cell culture supernatant was amplified by RT-PCR in the presence of NS5 universal flavivirus primers and directly sequenced. Results of BLAST search indicated that this sequence shares 93% nucleotide similarity with the sequence of SLEV (strain-MSI.7, confirmed by RT-PCR performed with SLEV specific primers. Since SLEV was identified as the cause of human disease, it is necessary to improve surveillance in order to achieve early detection of this agent in the state of São Paulo and in Brazil. This finding is also an alert to health professionals about the need for more complete clinical and epidemiological investigations of febrile illnesses as in the reported case. SLEV infections can be unrecognized or confused with other ones caused by an arbovirus, such as dengue.O presente estudo relata o isolamento do vírus da encefalite São Luis (SLEV de um caso febril humano suspeito de dengue, em São Pedro, Estado de São Paulo.

A high-speed, digitized video system was used for the eye-movement recording. The subject was asked to fixate a far target at different horizontal gaze angles with contact lenses inserted. Data from the subject while fixating at far without refractive correction and at near (at a convergence angle of 60 PD, were used for comparison. The eXpanded Nystagmus Acuity Function (NAFX was used to evaluate the foveation quality at each gaze angle. Contact lenses broadened the highfoveation-quality range of gaze angles in this subject. The broadening was comparable to that achieved during 60 PD of convergence although the NAFX values were lower. Contact lenses allowed the subject to see “more” (he had a wider range of high-foveation-quality gaze angles and “better” (he had improved foveation at each gaze angle. Instead of being contraindicated by INS, contact lenses emerge as a potentially important therapeutic option. Contact lenses employ afferent feedback via the ophthalmic division of the V cranial nerve to damp INS slow phases over a broadened range of gaze angles. This supports the proprioceptive hypothesis of INS improvement.Keywords: contact lenses, infantile nystagmus, visual function

    2013-11-01

    The following report explains the moisture-related concerns for High R-value wall assemblies and discusses past Building America research work that informs this study. Hygrothermal simulations were prepared for several common approaches to High R-value wall construction in six cities (Houston, Atlanta, Seattle, St. Louis, Chicago, and International Falls) representing a range of climate zones (2, 3, 4C, 4, 5A, and 7, respectively). The simulations are informed by experience gained from past research in this area and validated by field measurement and forensic experience. The modeling program was developed to assess the moisture durability of the wall assemblies based on three primary sources of moisture: construction moisture, air leakage condensation, and bulk water leakage. The peak annual moisture content of the wood based exterior sheathing was used to comparatively analyze the response to the moisture loads for each of the walls in each given city. Walls which experienced sheathing moisture contents between 20% and 28% were identified as risky, whereas those exceeding 28% were identified as very high risk. All of the wall assemblies perform well under idealized conditions. However, only the walls with exterior insulation, or cavity insulation which provides a hygrothermal function similar to exterior insulation, perform adequately when exposed to moisture loads. Walls with only cavity insulation are particularly susceptible to air leakage condensation. None of the walls performed well when a precipitation based bulk water leak was introduced to the backside of the sheathing, emphasizing the importance of proper flashing details.

    La Caille was one of the observational astronomers and geodesists who followed Newton in developing ideas about celestial mechanics and the shape of the earth. He provided data to the great 18th-century mathematicians involved in understanding the complex gravitational effects that the heavenly bodies have on one another. Observing from the Cape of Good Hope, he made the first ever telescopic sky survey and gave many of the southern constellations their present-day names. He measured the paths of the planets and determined their distances by trigonometry. In addition, he made a controversial measurement of the radius of the earth that seemed to prove it was pear-shaped. On a practical level, La Caille developed the method of `Lunars' for determining longitudes at sea. He mapped the Cape. As an influential teacher he propagated Newton's theory of universal gravitation at a time when it was only beginning to be accepted on the European continent.

    An overview of the amazing series of successive and diverse items worked on by the chemist and physicist Pasteur starts with the asymmetry of paratartrates, switches over to the fermentations and ends in the fight against diseases of invertebrates and vertebrates, including man. It is the wonderful story of an exceptional contribution to the advancement of knowledge, which was made possible by his keen observation skill, his rigorous and innovative methods and his careful judgement. A retrospective analysis of the inner man may impair somewhat the fame of Pasteur. He was a lonely man, in need of solitude to be able to make full use of his thinking capacity, foreboding secretiveness and shrewdness , which are contradictory to his careful writing down day after day of all the details of his thinking and research in his notebooks by now available to the scientific community. He was furthermore selfish, domineering, inflexible, impulsive and inclined to engage in endless controversies. But on the contrary his motivation to accept new assignments was subordinate to their public welfare value and as a rule he endeavoured to work on the problems in the field and in association with those concerned. He was courageous when struck by a cerebral hemorrhage at middle age, so that its aftermath hardly hampered his research activities. The dimness cast on his personality is not up to his pioneer role within a general conservative climate among the medical and even scientific profession, antagonistic to innovation. Pasteur has been a founder of stereochemistry, microbiology and its applications, immunology, bacterial vaccines, pasteurisation and a promotor of prevention and hygiene. These overwhelming achievements justify to keep alive the recognition of the outstanding stature of Pasteur.

    Henry Toussaint (1847-1890) is a veterinary who studied in Veterinary School of Lyon with his great master Auguste Chauveau the famous physiologist. This place is the First School founded in Europe at the end of the XVIIIth century and has opened a way of thinking. His carrer brilliant and rich begins first in Lyon and then when he is named Professor of Anatomy and Physiology at the Veterinary School of Toulouse. Doctor of Science and Doctor of Medecine Toussaint applies "the experimental method" to his research in his laboratory and makes a lot of publications. He starts with Anatomy, then Physiology and soon he prioritizes his research to infestious diseases which cause serious damage to cattle in this time. He developes his own methods about anthrax an its "bacteridie", its nature, its way of culture and especially he studies the physiopathology of this disease. Pasteur is a renowned scientist who does study Microbiology at the same time in his laboratory in Paris, and precisely anthrax. He has explained his theories about "microbes" and has predominant advice. Toussaint admires Pasteur; in the year 1879 he finds first and isolates the microbe of "cholera des poules" (now Pasteurella) and gives Pasteur this new germ which will be used by Pasteur for his particular works about reducing of virulence by successive subcultures. In 1880 with his publishing on July 12 at the Academy of Science, Toussaint presents his successful result with an attenuated vaccine against anthrax: he has got protection against anthrax for dogs and sheep by using a vaccine which he has reduced off virulence by chemical manner. Academy congratulates him. Pasteur jealous of one's reputation contests the demonstration of Toussaint because he does not believe in the chemical method too different from his tests but will make use of this method for an experience open to the public in Pouilly-le-Fort in 1881. After this promotional event Pasteur will product and sell vaccines maked in his laboratory in Paris with the first chemical method of Toussaint. Pasteur gets glory and money. In the following time Toussaint tries another research on tuberculosis but soon he feels the first attacks of a neurologic illness and inescapably his mind declines until the death in 1890.

  9. Nicolas-Louis de La Caille: Astronomer and Geodesist

    Science.gov (United States)

    Glass, I. S.

    La Caille was one of the observational astronomers and geodesists who followed Newton in developing ideas about celestial mechanics and the shape of the earth. He provided data to the great 18th-century mathematicians involved in understanding the complex gravitational effects that the heavenly bodies have on one another. Observing from the Cape of Good Hope, he made the first ever telescopic sky survey and gave many of the southern constellations their present-day names. He measured the paths of the planets and determined their distances by trigonometry. In addition, he made a controversial measurement of the radius of the earth that seemed to prove it was pear-shaped. On a practical level, La Caille developed the method of `Lunars' for determining longitudes at sea. He mapped the Cape. As an influential teacher he propagated Newton's theory of universal gravitation at a time when it was only beginning to be accepted on the European continent. This book gives the most comprehensive overview so far available of La Caille's life and work, showing how he interacted with his often difficult colleagues. It places special emphasis on his life at, and his observations and comments on, the Cape of Good Hope, where he spent the years 1751-53.

    Maupertuis was one of the most important scientists and original thinkers of the 18th century. He refuted the preformationist theories of the time, and from his study of the inheritance of genetic traits proposed various ideas which forecast the genetic theory of inheritance. He applied the concept of probability to genetic problems and introduced experimental breeding as a means of studying the inheritance of genetic traits in animals. However, he considered his greatest contribution to science to be the 'Principle of Least Action'. Yet paradoxically it was this, through the vitriolic attacks by Voltaire which it engendered, which resulted in his work being largely ignored until recent times. PMID:3050101

    2011-10-01

    Full Text Available The compiler of this dictionary is perhaps the first and only person to have attempted to produce a dictionary of this 'language' or register, and he should be complemented on this. This is a dictionary in a class of its own, i.e. a spe-cialised dictionary written to capture the vocabulary of Tsotsitaal, a language which may be regarded as 'obsolete' (or at least 'endangered' due to its nature and the versatility associated with it. It is gradually deteriorating and disap-pearing while changing from the original language of Sophiatown into various regional versions corrupted by the various other languages of South Africa. The compiler does not seem to have been motivated by knowledge of or experi-ence in dictionary writing, but by a desire to preserve the vocabulary of the language he loves, and to share his knowledge with future generations who may have been unfortunate not to have encountered the lifestyle of Sophia-town.

    路易斯·巴斯德(Louis Pasteur,1822-12-27 ~ 1895-09-28)是法国伟大的科学家,他发明了狂犬病疫苗,并于1885年7月6日,首次给被狂犬严重咬伤的9岁男童约瑟夫·迈斯特(Joseph Meister,1876-02-21~1940-06-24)治疗并获得成功.从此,人们普遍将巴斯德使用狂犬病疫苗首次对人进行接种的这一日期(7月6日),作为了人类历史上用人工制备疫苗来征服传染病的时代起点.到2015年7月6日,历史的车轮已经走过了漫长的130年.纵观巴斯德的科学生涯,可以大致划分为3个阶段:①1856年前的化学年代;②以1856年研究发酵开始接触到了微生物为起点,进入生命科学年代;③以1865年研究蚕病为起步标志,进入医学(包括兽医学)年代.巴斯德在化学、生命科学、医学乃至农业领域都有独到的发现与研究,然而使他留芳千古的是病原学说的创立和免疫预防接种的发明.在发明疫苗的探索中,巴斯德找到了开启疫苗大门的钥匙——控制病原体的毒力.他发现了使鸡霍乱病原细菌——多杀巴斯德氏菌(Pasteurella multocida)自然减毒的途径,更可贵的是使炭疽芽孢杆菌发生人为的毒力变异,并成功发明了鸡霍乱疫苗、炭疽减毒疫苗.在对狂犬病疫苗研究中通过采用兔脑传代的方法,建立了由街毒向固定毒演变的狂犬病病毒固定毒经典理论,并成功研制出了安全有效的狂犬病疫苗,同时建立了对狂犬病的巴斯德预防治疗法.狂犬病疫苗百年来虽不断地推陈出新,但巴斯德创造的原理仍为经典的指导原则.

  20. Under-Ice Operations with AUVS in High Latitudes

    2012-12-01

    In 2010 and 2011, ISE Explorer Autonomous Underwater Vehicles (AUV), built for Natural Resources Canada (NRCan), were deployed to Canada's high Arctic. The mission was to undertake under-ice bathymetric surveys supporting Canada's submission under the United Nations Convention on the Law of the Sea (UNCLOS). During these deployments several under-ice records were broken and several new technologies were demonstrated. The NRCan AUV is a 5000 meter depth rated vehicle, with several innovative additions to make it suitable for arctic survey work. Most notable are a depth rated variable ballast system, a 1300 Hz long-range homing system, and under-ice charging and data transfer capabilities. The Explorer's range was extended to approximately 450 km by adding a hull section to accommodate extra batteries. The scientific payload onboard included a Seabird SBE49 Conductivity-Temperature-Depth (CTD) sensor, Knudsen singlebeam echosounder, and a Kongsberg Simrad EM2000 multibeam echosounder. In 2010, operations were conducted from an ice camp near Borden Island (78°14'N, 112°39'W) operating through an ice hole. Following several test missions, the AUV spent 10 days surveying under ice before being successfully recovered. In total, close to 1100 km of under-ice survey was undertaken at depths to 3160 meters. A further set of operations was carried out in August and September 2011 from the Canadian Icebreaker CCGS Louis St. Laurent operating with the American Icebreaker USCGS Healy. Here the operations were much further north to latitudes of 88°30' N and to depths of 3500 meters. In this paper, the 2010 ice camp and the 2011 icebreaker missions are described, with an outline of technology developments that were undertaken, the preparations that were necessary for the success of the missions and finally, the outcome of the missions themselves.

In individuals with diabetes mellitus, blood pressure (BP levels > 130/80 mmHg confer an even higher risk for cardiovascular and renal disease, and these patients will benefit from aggressive antihypertensive treatment using a combination of agents. β‑blockers are playing an increasingly important role in the management of hypertension in high-risk patients. β‑blockers are a heterogeneous class of agents, and this review presents the differences between β‑blockers and provides evidence-based protocols to assist in understanding dose equivalence in the selection of an optimal regimen in patients with complex needs. The clinical benefits provided by β‑blockers are only effective if patients adhere to medication treatment long term. β‑blockers with proven efficacy, once-daily dosing, and lower side effect profiles may become instrumental in the treatment of hypertensive diabetic and nondiabetic patients.Keywords: antihypertensive, blood pressure, atenolol, carvedilol, labetalol, metoprolol, nebivolol

    The author considered the small part of the population whose members score highly on both the Social Dominance Orientation scale and the Right-Wing Authoritarianism scale. Studies of these High SDO-High RWAs, culled from samples of nearly 4000 Canadian university students and over 2600 of their parents and reported in the present article, reveal that these dominating authoritarians are among the most prejudiced persons in society. Furthermore, they seem to combine the worst elements of each kind of personality, being power-hungry, unsupportive of equality, manipulative, and amoral, as social dominators are in general, while also being religiously ethnocentric and dogmatic, as right-wing authoritarians tend to be. The author suggested that, although they are small in number, such persons can have considerable impact on society because they are well-positioned to become the leaders of prejudiced right-wing political movements.

  12. Staged, High-Pressure Oxy-Combustion Technology: Development and Scale-Up

    Energy Technology Data Exchange (ETDEWEB)

    Axelbaum, Richard; Xia, Fei; Gopan, Akshay; Kumfer, Benjamin

    2014-09-30

    Washington University in St. Louis and its project partners are developing a unique pressurized oxy-combustion process that aims to improve efficiency and costs by reducing the recycling of flue gas to near zero. Normally, in the absence of recycled flue gas or another inert gas, combustion of fuel and oxygen results in a dramatic increase in temperature of the combustion products and radiant energy, as compared to combustion in air. High heat flux to the boiler tubes may result in a tube surface temperatures that exceed safe operating limits. In the Staged Pressurized Oxy-Combustion (SPOC) process, this problem is addressed by staging the delivery of fuel and by novel combustion design that allows control of heat flux. In addition, the main mode of heat transfer to the steam cycle is by radiation, as opposed to convection. Therefore, the requirement for recycling large amounts of flue gas, for temperature control or to improve convective heat transfer, is eliminated, resulting in a reduction in auxiliary loads. The following report contains a detailed summary of scientific findings and accomplishments for the period of Oct. 1, 2013 to Sept 30, 2014. Results of ASPEN process and CFD modelling activities aimed at improving the SPOC process and boiler design are presented. The effects of combustion pressure and fuel moisture on the plant efficiency are discussed. Combustor pressure is found to have only a minor impact beyond 16 bar. For fuels with moisture content greater than approx 30%, e.g. coal/water slurries, the amount of latent heat of condensation exceeds that which can be utilized in the steam cycle and plant efficiency is reduced significantly. An improved boiler design is presented that achieves a more uniform heat flux profile. In addition, a fundamental study of radiation in high-temperature, high-pressure, particle-laden flows is summarized which provides a more complete understanding of heat transfer in these unusual conditions and to allow for

The new results from the SMC experiment have generated a buzz of theoretical activity. Our involvement with the D0 experiment and the upgrade has increased substantially during the past two years so that we now have six people heavily committed and making what can only be described as a large and disproportionate impact on D0 physics output. Some of the new developments made here at Rice in Neural Network and Probability Density Estimation techniques for data analysis promise to have applications both in D0 and beyond. We report a load of new results from our high-pt jet photoproduction experiment. In addition we have been working on KTeV, albeit without having adequate funding for this work. Progress on the theoretical front has been nothing short of amazing, as is reported herein. In a grand lecture tour during this sabbatical year, Paul Stevenson has already reported his breakthroughs at ten institutions, including CERN, Oxford, Cambridge, Rutherford Lab, Imperial College, and Durham University. The group at Rice University has had an exceptionally productive year and we are justifiably proud of the progress which is reported here

    International Nuclear Information System (INIS)

    The monitoring program at the SLAPS measures radon gas concentrations in air; external gamma dose rates; and uranium, thorium, and radium concentrations in surface water, groundwater, and sediment. To assess the potential effect of the SLAPS on the public health, the radiation dose was calculated for the maximally exposed individual. Based on the scenario described in this report, the maximally exposed individual would receive an external exposure approximately equivalent to 5.5 percent of the DOE radiation protection standard of 100 mrem/yr. This exposure is approximately the same as a person would receive from increased cosmic radiation during six round-trip flights from New York to Los Angeles (due to greater amounts of cosmic radiation at higher altitudes). The dose to the population within an 80-km (50-mi) radius of the SLAPS that would result from radioactive materials present at the site would be indistinguishable from the dose the population would receive from naturally occurring radioactive sources. Results of 1987 monitoring show that the SLAPS is in compliance with the DOE radiation protection standard. 13 refs., 5 figs., 11 tabs

    When elected a member of Académie de médecine in 1873, Pasteur was well known for his achievements in chemistry, fermentation and silk worm diseases. He denied spontaneity of diseases, their cause are living germs. Passionate disputations took place in Academy on subjects of septicaemia, childbirth fever, or fowl cholera. In 1881, his success was obtained by vaccination of sheep against epidemic anthrax: his method of virus action softening was available for many human infections diseases, in spite of many disputations. The same method applied to rabies gave him universal glory. When he died in 1895, his views on infections diseases were accepted by Academie de medecine and all over the world.

    2014-05-01

    Full Text Available Research focuses on Lois Goulds complex position in feminism movements as displayed by the pessimistic tone in one of her works. The primary data for this research were taken from the short story X: A Fabulous Childs Story, published in 1972. The research used qualitative method that lies on library research, and to help analyze the topic, books, websites, and scientific journals were used. Kate Millets concept of an androgyny was also applied in order to study further about the character of X. The result of the discussion shows that even though considered progressive for its era for its effort to deconstruct rigid gender divisions, this short story also comes with an irony with its ending. The ending demonstrates that human beings cannot be free from sex and gender barriers. This result supports the idea that Gould is trapped between the feminist and the antifeminist movement.

    An open-bottom and a closed-bottom mesocosm were developed to investigate the release of mercury from sediments to the water column in a frozen freshwater lake. The mesoscosms were deployed in a hole in the ice and particulate mercury (Hg{sub P}) and total dissolved mercury (TDHg) were measured in sediments and in water column vertical profiles. In addition, dissolved gaseous mercury (DGM) in water and mercury water/airflux were quantified. Concentrations of TDHg, DGM, and mercury flux were all higher in the open-bottom mesocosm than in the closed-bottom mesocosm. In this paper we focus on the molecular diffusion of mercury from the sediment in comparison with the TDHg accumulation in the water column. We conclude that the molecular diffusion and sediment resuspension play a minor role in mercury release from sediments suggesting that solute release during ebullition is an important transport process for mercury in the lake. - In a frozen lake Hg is released from contaminated sediments mainly due to gas ebullition and molecular diffusion plays a minor role.

  10. Modelling sea ice for climate studies: recent advances and future challenges (Louis Agassiz Medal Lecture)

    Science.gov (United States)

    Fichefet, Thierry

    2016-04-01

    Since the beginning of satellite measurements in 1979, the summer Arctic sea ice extent has shrunk at a mean rate of ~12% per decade, and there is evidence that the rate of decline has accelerated over the last decade. Current global climate models project further decrease in Arctic sea ice areal coverage through the 21st century if atmospheric greenhouse gas concentrations continue to increase. However, rates of loss vary greatly between models, yielding a large uncertainty as to when a seasonally ice-free Arctic Ocean may be realized. Narrowing this uncertainty is of crucial importance since such changes in the Arctic sea ice cover might have profound ramifications, including the global ocean circulation and heat budget, regional ecosystems and wildlife, the indigenous human population, and commercial exploration and transportation. Regarding the Antarctic sea ice, its extent has been observed to slightly increase during the last 37 years, which appears puzzling in a global warming context. Several hypotheses have been proposed to explain this feature, but the issue is far from being settled. On the other hand, the majority of global climate models simulate a decreasing trend in Antarctic sea ice extent over this period, which questions the validity of their Antarctic sea ice projections for the coming decades. In this lecture, we show through simulations conducted with the state of the art Louvain-la-Neuve Sea Ice Model (LIM) coupled to the Nucleous European Modelling of the Ocean (NEMO) platform that a number of small-scale sea ice processes, which are omitted or crudely represented in global climate models (in particular, the subgrid-scale sea ice thickness distribution, the thermodynamics and dynamics of brine pockets trapped within sea ice, processes related to snow on top of sea ice, including surface melt ponds, the sea ice mechanical deformation, and the subgrid-scale heterogeneity of atmosphere-ice-ocean interactions), play a significant role in determining the mean state and variability of sea ice in both hemispheres. There is therefore an urgent need to account for these processes in the next generation of global climate models. We also demonstrate that sea ice data assimilation in models is a powerful tool to calibrate sea ice parameters and to improve seasonal sea ice predictions. Furthermore, we show that it is possible to understand to a certain extent differences between models and to reduce sea ice projection uncertainties by using appropriate sea ice process-oriented diagnostics and emergent constraints. Finally, we discuss possible future developments and challenges in sea ice modelling for climate studies.

  9. Flooding of the Great River during the Common Era: A Paleohydrological Record of High Magnitude Flood Events from the Central Mississippi River Valley

    Science.gov (United States)

    Williams, J. W.; Munoz, S. E.; Gruley, K. E.; Massie, A.

    2014-12-01

    Streamflow characteristics are known to be sensitive to changes in climate, but few continuous records of flooding exist to evaluate the response of hydrological systems to centennial- and millennia-scale climate changes. Here, we present sedimentary records from two oxbow lakes (Horseshoe Lake and Grassy Lake, Illinois, USA) in the central Mississippi River valley (CMRV) that display abrupt shifts in sediment composition and particle-size consistent with deposition by floodwaters immediately following inundation of the floodplain. The sedimentary record at Horseshoe Lake begins ca. AD 100 and displays five major flood events, with four of these occurring after ca. AD 1100. Situated 200 km downstream, the record from Grassy Lake begins later, ca. AD 800, and also shows four major flood events after ca. AD 1100. An analysis of synchronicity using Bayesian age modelling software shows high likelihoods that the four overlapping flood events occurred at the same time, confirming that these events resulted from flooding of the Mississippi River. The most recent event we record at AD 1840 ± 50 corresponds to the AD 1844 flood, the largest flood by discharge (37 m3/s) measured by the gauging station at St. Louis, Missouri, indicating that our sedimentary records document high magnitude flood events. Together, our two sedimentary records show a major shift in the frequency of high magnitude flooding in the central Mississippi River at ca. AD 1100. From AD 100 - AD 1100, only one relatively subtle flood event is recorded, but from AD 1100 - AD 1900, four high magnitude floods deposited distinctive sediment at both sites. The period of infrequent flooding corresponds to a time of agricultural intensification and population growth in the CMRV, while the entire region was abandoned when flood frequency increased. The pronounced shift in flood frequency we observe in our records at ca. AD 1100 begins during the Medieval Climate Anomaly (MCA; AD 950 - AD 1250), a period of

  16. High Efficiency Integrated Space Conditioning, Water Heating and Air Distribution System for HUD-Code Manufactured Housing

    Energy Technology Data Exchange (ETDEWEB)

    Henry DeLima; Joe Akin; Joseph Pietsch

    2008-09-14

    Recognizing the need for new space conditioning and water heating systems for manufactured housing, DeLima Associates assembled a team to develop a space conditioning system that would enhance comfort conditions while also reducing energy usage at the systems level. The product, Comboflair® was defined as a result of a needs analysis of project sponsors and industry stakeholders. An integrated system would be developed that would combine a packaged airconditioning system with a small-duct, high-velocity air distribution system. In its basic configuration, the source for space heating would be a gas water heater. The complete system would be installed at the manufactured home factory and would require no site installation work at the homesite as is now required with conventional split-system air conditioners. Several prototypes were fabricated and tested before a field test unit was completed in October 2005. The Comboflair® system, complete with ductwork, was installed in a 1,984 square feet, double-wide manufactured home built by Palm Harbor Homes in Austin, TX. After the home was transported and installed at a Palm Harbor dealer lot in Austin, TX, a data acquisition system was installed for remote data collection. Over 60 parameters were continuously monitored and measurements were transmitted to a remote site every 15 minutes for performance analysis. The Comboflair® system was field tested from February 2006 until April 2007. The cooling system performed in accordance with the design specifications. The heating system initially could not provide the needed capacity at peak heating conditions until the water heater was replaced with a higher capacity standard water heater. All system comfort goals were then met. As a result of field testing, we have identified improvements to be made to specific components for incorporation into production models. The Comboflair® system will be manufactured by Unico, Inc. at their new production facility in St. Louis

    Full Text Available Piezoelectric composites are a class of functional materials consisting of piezoelectric active materials and non-piezoelectric passive polymers, mechanically attached together to form different connectivities. These composites have several advantages compared to conventional piezoelectric ceramics and polymers, including improved electromechanical properties, mechanical flexibility and the ability to tailor properties by using several different connectivity patterns. These advantages have led to the improvement of overall transducer performance, such as transducer sensitivity and bandwidth, resulting in rapid implementation of piezoelectric composites in medical imaging ultrasounds and other acoustic transducers. Recently, new piezoelectric composite transducers have been developed with optimized composite components that have improved thermal stability and mechanical quality factors, making them promising candidates for high temperature, high power transducer applications, such as therapeutic ultrasound, high power ultrasonic wirebonding, high temperature non-destructive testing, and downhole energy harvesting. This paper will present recent developments of piezoelectric composite technology for high temperature and high power applications. The concerns and limitations of using piezoelectric composites will also be discussed, and the expected future research directions will be outlined.

    A regenerative laser amplifier system generates high peak power and high energy per pulse output beams enabling generation of X-rays used in X-ray lithography for manufacturing integrated circuits. The laser amplifier includes a ring shaped optical path with a limited number of components including a polarizer, a passive 90 degree phase rotator, a plurality of mirrors, a relay telescope, and a gain medium, the components being placed close to the image plane of the relay telescope to reduce diffraction or phase perturbations in order to limit high peak intensity spiking. In the ring, the beam makes two passes through the gain medium for each transit of the optical path to increase the amplifier gain to loss ratio. A beam input into the ring makes two passes around the ring, is diverted into an SBS phase conjugator and proceeds out of the SBS phase conjugator back through the ring in an equal but opposite direction for two passes, further reducing phase perturbations. A master oscillator inputs the beam through an isolation cell (Faraday or Pockels) which transmits the beam into the ring without polarization rotation. The isolation cell rotates polarization only in beams proceeding out of the ring to direct the beams out of the amplifier. The diffraction limited quality of the input beam is preserved in the amplifier so that a high power output beam having nearly the same diffraction limited quality is produced.

    2001-01-01

    New kicker magnet systems and their related technologies are being developed and tested at KEK. The kickers are to be used both for the injection and for the fast extraction of two rings, the 50 GeV proton synchrotron in the 'Joint Project' of JAERI-KEK and the PRISM/FFAG ring for the muon beam. In order to obtain a sufficient kick on the high-intensity beam in the 50 GeV proton ring, the kicker systems must have both large apertures and high fields. In addition to this, the PRISM/FFAG ring demands muon beams with a high repetition rate of injection and extraction. The requested repetition rate is 1 kHz or higher. In order to fulfill those demands, new technologies have been introduced and are now being tested. Among them are high-power IGBT modules, a subordinated-gating system, 1 kHz repetition pulsed power supply, and kickers with magnetic-alloy cores used as return yokes.

    Generalized lock-in amplifiers use digital cavities with Q-factors as high as 5X10^8. In this letter, we show that generalized lock-in amplifiers can be used to analyze microwave (giga-hertz) signals with a precision of few tens of hertz. We propose that the physical changes in the medium of propagation can be measured precisely by the ultra-high precision measurement of the signal. We provide evidence to our proposition by verifying the Newton's law of cooling by measuring the effect of change in temperature on the phase and amplitude of the signals propagating through two calibrated cables. The technique could be used to precisely measure different physical properties of the propagation medium, for example length, resistance, etc. Real time implementation of the technique can open up new methodologies of in-situ virtual metrology in material design.

  14. Photoproduction at High Energy and High Intensity

    CERN Multimedia

    2002-01-01

    The photon beam used for this programme is tagged and provides a large flux up to very high energies (150-200 GeV). It is also hadron-free, since it is obtained by a two-step conversion method. A spectrometer is designed to exploit this beam and to perform a programme of photoproduction with a high level of sensitivity (5-50 events/picobarn).\\\\ \\\\ Priority will be given to the study of processes exhibiting the point-like behaviour of the photon, especially deep inelastic Compton scattering. The spectrometer has two magnets. Charged tracks are measured by MWPC's located only in field-free regions. Three calorimeters provide a large coverage for identifying and measuring electrons and photons. An iron filter downstream identifies muons. Most of the equipment is existing and recuperated from previous experiments.

    1983-03-01

    A program to develop a special high energy density, high power transfer capacitor to operate at frequency of 40 kHz, 600 V rms at 125 A rms plus 600 V dc bias for space operation. The program included material evaluation and selection, a capacitor design was prepared, a thermal analysis performed on the design. Fifty capacitors were manufactured for testing at 10 kHz and 40 kHz for 50 hours at Industrial Electric Heating Co. of Columbus, Ohio. The vacuum endurance test used on environmental chamber and temperature plate furnished by Maxwell. The capacitors were energized with a special power conditioning apparatus developed by Industrial Electric Heating Co. Temperature conditions of the capacitors were monitored by IEHCo test equipment. Successful completion of the vacuum endurance test series confirmed achievement of the main goal of producing a capacitor or reliable operation at high frequency in an environment normally not hospitable to electrical and electronic components. The capacitor developed compared to a typical commercial capacitor at the 40 kHz level represents a decrease in size and weight by a factor of seven.

    McDermott, D. B.; Luhmann, N. C., Jr.

    1984-08-01

    There is currently much interest in the development of moderate to high power (1 kW - 1 MW) millimeter wave sources. Considered applications are mainly related to radar and communication systems. There are, however, also applications in plasma diagnostics, heating, and the nondestructive testing of dielectrics. The dominant source of high-power, high-frequency radiation has become the gyrotron. Jory et al. (1983) have reported operation of a 60 GHz, CW gyrotron, producing output powers in excess of 200 kW. High power, compact submillimeter-wave sources have become possible by making use of the concept of a high-harmonic gyrotron, in which the magnetic field can be reduced by an order of magnitude. Attention is given to synchronism, negative-mass instability, energy requirements, oscillators, efficiency, high power, dielectric loading, the peniotron, and amplifiers.

Better tools need to be identified to predict cardiac complications of anthracycline chemotherapy. Materials and methods: We investigated the utility of high-sensitivity cardiac troponin T (hscTnT, N-terminal pro-B-type natriuretic peptide, cardiac troponin T and I, and creatine kinase (CK-MB in cancer patients receiving anthracycline-based chemotherapy, in order to determine whether baseline levels or changes in these biomarkers may help predict the onset of congestive heart failure. Results: Eighteen consecutive patients with a pathologic diagnosis of breast cancer or non-Hodgkin lymphoma were enrolled. The median dose of doxorubicin exposure was 240 mg/m2 (range 240–400 mg/m2. After treatment with doxorubicin, the hscTnT increased to 19.1 pg/mL (P<0.001. CKMB and N-terminal pro-B-type natriuretic peptide levels increased to 1.1 ng/mL and 88.3 pg/mL, respectively (P=0.02. When subjects who had a decline in left ventricular ejection fraction (LVEF by equilibrium radionuclide ventriculography were compared to those who did not have a change in LVEF, there was a suggestion that those subjects with an elevated baseline hscTnT were more likely to have a decline in LVEF (2.7 pg/mL and 0.1 pg/mL, respectively; P=0.07.

  16. Phononic High Harmonic Generation

    CERN Document Server

    Ganesan, Adarsh; Seshia, Ashwin A

    2016-01-01

    This paper reports the first experimental evidence for phononic low-order to high-order harmonic conversion leading to high harmonic generation. Similar to parametric resonance, phononic high harmonic generation is also mediated by a threshold dependent instability of a driven phonon mode. Once the threshold for instability is met, a cascade of harmonic generation processes is triggered. Firstly, the up-conversion of first harmonic phonons into second harmonic phonons is established. Subsequently, the down-conversion of second harmonic phonons into first harmonic phonons and conversion of first and second harmonic phonons into third harmonic phonons occur. On the similar lines, an eventual conversion of third harmonic phonons to high orders is also observed to commence. This surprising physical pathway for phononic low-order to high-order harmonic conversion may find general relevance to other physical systems.

  1. High Efficiency, High Performance Clothes Dryer

    Energy Technology Data Exchange (ETDEWEB)

    Peter Pescatore; Phil Carbone

    2005-03-31

    This program covered the development of two separate products; an electric heat pump clothes dryer and a modulating gas dryer. These development efforts were independent of one another and are presented in this report in two separate volumes. Volume 1 details the Heat Pump Dryer Development while Volume 2 details the Modulating Gas Dryer Development. In both product development efforts, the intent was to develop high efficiency, high performance designs that would be attractive to US consumers. Working with Whirlpool Corporation as our commercial partner, TIAX applied this approach of satisfying consumer needs throughout the Product Development Process for both dryer designs. Heat pump clothes dryers have been in existence for years, especially in Europe, but have not been able to penetrate the market. This has been especially true in the US market where no volume production heat pump dryers are available. The issue has typically been around two key areas: cost and performance. Cost is a given in that a heat pump clothes dryer has numerous additional components associated with it. While heat pump dryers have been able to achieve significant energy savings compared to standard electric resistance dryers (over 50% in some cases), designs to date have been hampered by excessively long dry times, a major market driver in the US. The development work done on the heat pump dryer over the course of this program led to a demonstration dryer that delivered the following performance characteristics: (1) 40-50% energy savings on large loads with 35 F lower fabric temperatures and similar dry times; (2) 10-30 F reduction in fabric temperature for delicate loads with up to 50% energy savings and 30-40% time savings; (3) Improved fabric temperature uniformity; and (4) Robust performance across a range of vent restrictions. For the gas dryer development, the concept developed was one of modulating the gas flow to the dryer throughout the dry cycle. Through heat modulation in a

    Prolonged altitude exposure even with acclimatization continues to present a physiological challenge to all organ systems including the central nervous system. We describe a case of a 41-year-old Caucasian female climber who suffered severe visual loss that was due to possible optic nerve pathology occurring during a high altitude expedition in the Himalayas. This case is atypical of classic high altitude cerebral oedema and highlights yet another danger of prolonged sojourn at extreme altitudes. PMID:27601532

    Full Text Available The high-density lipoprotein cholesterol (HDL-C is considered anti-atherogenic good cholesterol. It is involved in reverse transport of lipids. Epidemiological studies have found inverse relationship of HDL-C and coronary heart disease (CHD risk. When grouped according to HDL-C, subjects having HDL-C more than 60 mg/dL had lesser risk of CHD than those having HDL-C of 40-60 mg/dL, who in turn had lesser risk than those who had HDL-C less than 40 mg/dL. No upper limit for beneficial effect of HDL-C on CHD risk has been identified. The goals of treating patients with low HDL-C have not been firmly established. Though many drugs are known to improve HDL-C concentration, statins are proven to improve CHD risk and mortality. Cholesteryl ester transfer protein (CETP is involved in metabolism of HDL-C and its inhibitors are actively being screened for clinical utility. However, final answer is still awaited on CETP-inhibitors.

    Full Text Available Drawing on John Agnew’s (1987 theoretical framework for the analysis of place (location, locale and sense of place and on Doreen Massey’s (1991 interpretation of Kilburn High Road (London, the contribution develops an analysis of the notion of place in the case study of Kilburn High Road by comparing the semantics emerging from Doreen Massey’s interpretation of Kilburn High Road in the late Nineties with those from a selection of noisy and unstructured volunteered geographic information collected from Flickr photos and Tweets harvested in 2014–2015. The comparison shows how sense of place is dynamic and changing over time and explores Kilburn High Road through the categories of location, locale and sense of place derived from the qualitative analysis of VGI content and annotations. The contribution shows how VGI can contribute to discovering the unique relationship between people and place which takes the form given by Doreen Massey to Kilburn High Road and then moves on to the many forms given by people experiencing Kilburn High Road through a photo, a Tweet or a simple narrative. Finally, the paper suggests that the analysis of VGI content can contribute to detect the relevant features of street life, from infrastructure to citizens’ perceptions, which should be taken into account for a more human-centered approach in planning or service management.

  12. High Caloric Diet for ALS Patients: High Fat, High Carbohydrate or High Protein

    2015-01-01

    Full Text Available ALS is a fatal motor neurodegenerative disease characterized by muscle atrophy and weakness, dysarthria, and dysphagia. The mean survival of ALS patients is three to five years, with 50% of those diagnosed dying within three years of onset (1. A multidisciplinary approach is crucial to set an appropriate plan for metabolic and nutritional support in ALS. Nutritional management incorporates a continuous assessment and implementation of dietary modifications throughout the duration of the disease. The nutritional and metabolic approaches to ALS should start when the diagnosis of ALS is made and should become an integral part of the continuous care to the patient, including nutritional surveillance, dietary counseling, management of dysphagia, and enteral nutrition when needed. Malnutrition and lean body mass loss are frequent findings in ALS patients necessitating comprehensive energy requirement assessment for these patients. Malnutrition is an independent prognostic factor for survival in ALS with a 7.7 fold increase in risk of death. Malnutrition is estimated to develop in one quarter to half of people with ALS (2. Adequate calorie and protein provision would diminish muscle loss in this vulnerable group of patients. Although appropriate amount of energy to be administered is yet to be established, high calorie diet is expected to be effective for potential improvement of survival; ALS patients do not normally receive adequate  intake of energy. A growing number of clinicians suspect that a high calorie diet implemented early in their disease may help people with ALS meet their increased energy needs and extend their survival. Certain high calorie supplements appear to be safe and well tolerated by people with ALS according to studies led by Universitäts klinikum Ulm's and, appear to stabilize body weight within 3 months. In a recent study by Wills et al., intake of high-carbohydrate low-fat supplements has been recommended in ALS patients (3

    2013-07-01

    A three year plan for thermal energy storage (TES) research was created at Sandia National Laboratories in the spring of 2012. This plan included a strategic goal of providing test capability for Sandia and for the nation in which to evaluate high temperature storage (>650ÀC) technology. The plan was to scope, design, and build a flow loop that would be compatible with a multitude of high temperature heat transfer/storage fluids. The High Temperature Storage Loop (HTSL) would be reconfigurable so that it was useful for not only storage testing, but also for high temperature receiver testing and high efficiency power cycle testing as well. In that way, HTSL was part of a much larger strategy for Sandia to provide a research and testing platform that would be integral for the evaluation of individual technologies funded under the SunShot program. DOEs SunShot program seeks to reduce the price of solar technologies to 6/kWhr to be cost competitive with carbon-based fuels. The HTSL project sought to provide evaluation capability for these SunShot supported technologies. This report includes the scoping, design, and budgetary costing aspects of this effort

    Full Text Available Nowadays, situations associated with high altitude such as mountaineering, aviation increasingly draw the attention of people. Gas pressure decreases and hypoxia is encountered when climbing higher. Physiological and pathological responses of human body to different heights are different. Therefore, physiological and pathological changes that may occur together with height and to know the clinical outcomes of these are important . Acute mountain sickness caused by high altitude and high altitude cerebral edema are preventable diseases with appropriate precautions. Atmospheric oxygen decreasing with height, initiates many adaptive mechanisms. These adaptation mechanisms and acclimatization vary widely among individuals because of reasons such as environmental factors, exercise and cold. High altitude causes different changes in the cardiovascular system with various mechanisms. Although normal individuals easily adapt to these changes, this situation can lead to undesirable results in people with heart disease. For this reason, it should be known the effective evaluation of the people with known heart disease before traveling to high altitude and the complications due to the changes with height and the recommendations can be made to these patients.

    2005-01-01

    A high temperature displacement sensor based on the principle of eddy-current is investigated. A new temperature compensation technique by using eddy-current effect is presented to satisfy the special requirement at high temperature up to 550℃. The experiment shows that the temperature compensation technique leads to good temperature stability for the sensors. The variation of the sensitivity as well as the temperature drift of the sensor with temperature compensation technique is only about 7.4% and 90~350 mV at 550℃ compared with that at room temperature, and that of the sensor without temperature compensation technique is about 31.2% and 2~3 V at 550℃ compared with that at room temperature. A new dynamic calibration method for the eddy-current displacement sensor is presented, which is very easy to be realized especially in high frequency and at high temperatures. The high temperature displacement sensors developed are successfully used at temperature up to 550℃ in a magnetic bearing system for more than 100 h.

    We present our imaging and spectroscopic observations of the host galaxies of two dark long bursts with anomalously high metallicities, LGRB 051022 and LGRB 020819B, which in conjunction with another LGRB event with an optical afterglow comprise the three LGRBs with high metallicity host galaxies in the Graham & Fruchter (2013) sample. In Graham & Fruchter (2013), we showed that LGRBs exhibit a strong and apparently intrinsic preference for low metallicity environments (12+log(O/H) < 8.4 in the KK04 scale) in spite of these three cases with abundances of about solar and above. These exceptions however are consistent with the general star-forming galaxy population of comparable brightness & redshift. This is surprising: even among a preselected sample of high metallicity LGRBs, were the metal aversion to remain in effect for these objects, we would expect their metallicity to still be lower than the typical metallicity for the galaxies at that luminosity and redshift. Therefore we deduce that it...

    The preferred embodiments are directed to a high-energy detector that is electrically shielded using an anode, a cathode, and a conducting shield to substantially reduce or eliminate electrically unshielded area. The anode and the cathode are disposed at opposite ends of the detector and the conducting shield substantially surrounds at least a portion of the longitudinal surface of the detector. The conducting shield extends longitudinally to the anode end of the detector and substantially surrounds at least a portion of the detector. Signals read from one or more of the anode, cathode, and conducting shield can be used to determine the number of electrons that are liberated as a result of high-energy particles impinge on the detector. A correction technique can be implemented to correct for liberated electron that become trapped to improve the energy resolution of the high-energy detectors disclosed herein.

    2016-02-01

    High-Tc superconductivity at interfaces has a history of more than a couple of decades. In this review we focus our attention on copper-oxide based heterostructures and multi-layers. We first discuss the technique, atomic layer-by-layer molecular beam epitaxy (ALL-MBE) engineering, that enabled High-Tc Interface Superconductivity (HT-IS), and the challenges associated with the realization of high quality interfaces. Then we turn our attention to the experiments which shed light on the structure and properties of interfacial layers, allowing comparison to those of single-phase films and bulk crystals. Both 'passive' hetero-structures as well as surface-induced effects by external gating are discussed. We conclude by comparing HT-IS in cuprates and in other classes of materials, especially Fe-based superconductors, and by examining the grand challenges currently laying ahead for the field.

    1994-01-01

    This article reviews available research studies of high-conflict divorce and its effects on children. Interparental conflict after divorce (defined as verbal and physical aggression, overt hostility, and distrust) and the primary parent's emotional distress are jointly predictive of more problematic parent-child relationships and greater child emotional and behavioral maladjustment. As a group, children of high-conflict divorce as defined above, especially boys, are two to four times more likely to be clinically disturbed in emotions and behavior compared with national norms. Court-ordered joint physical custody and frequent visitation arrangements in high-conflict divorce tend to be associated with poorer child outcomes, especially for girls. Types of intervention programs and social policy appropriate for these kinds of families are presented.

    2016-01-01

    In this short review we will highlight some of the recent advancements in the field of high-resolution laboratory spectroscopy that meet the needs dictated by the advent of highly sensitive and broadband telescopes like ALMA and SOFIA. Among these is the development of broadband techniques for the study of complex organic molecules, like fast scanning conventional absorption spectroscopy based on multiplier chains, chirped pulse instrumentation, or the use of synchrotron facilities. Of similar importance is the extension of the accessible frequency range to THz frequencies, where many light hydrides have their ground state rotational transitions. Another key experimental challenge is the production of sufficiently high number densities of refractory and transient species in the laboratory, where discharges have proven to be efficient sources that can also be coupled to molecular jets. For ionic molecular species sensitive action spectroscopic schemes have recently been developed to overcome some of the limita...

  2. High frequency energy measurements

    International Nuclear Information System (INIS)

    High-frequency (> 100 MHz) energy measurements present special problems to the experimenter. Environment or available electronics often limit the applicability of a given detector type. The physical properties of many detectors are frequency dependent and in some cases, the physical effect employed can be frequency dependent. State-of-the-art measurements generally involve a detection scheme in association with high-speed electronics and a method of data recording. Events can be single or repetitive shot requiring real time, sampling, or digitizing data recording. Potential modification of the pulse by the detector and the associated electronics should not be overlooked. This presentation will review typical applications, methods of choosing a detector, and high-speed detectors. Special considerations and limitations of some applications and devices will be described

    Lombardo, M P

    2012-01-01

    I review recent results on QCD at high temperature on a lattice. Steady progress with staggered fermions and Wilson type fermions allow a quantitative description of hot QCD whose accuracy in many cases parallels that of zero temperature studies. Simulations with chiral quarks are coming of age, and togheter with theoretical developments trigger interesting developments in the analysis of the critical region. Issues related with the universality class of the chiral transition and the fate of the axial symmetry are discussed in the light of new numerical and analytical results. Transport coefficients and analysis of bottomonium spectra compare well with results of heavy ion collisions at RHIC and LHC. Model field theories, lattice simulations and high temperature systematic expansions help building a coherent picture of the high temperature phase of QCD. The (strongly coupled) Quark Gluon Plasma is heavily investigated, and asserts its role as an inspiring theoretical laboratory.

    Disclosed are methods for forming carbon-based fillers as may be utilized in forming highly thermal conductive nanocomposite materials. Formation methods include treatment of an expanded graphite with an alcohol/water mixture followed by further exfoliation of the graphite to form extremely thin carbon nanosheets that are on the order of between about 2 and about 10 nanometers in thickness. Disclosed carbon nanosheets can be functionalized and/or can be incorporated in nanocomposites with extremely high thermal conductivities. Disclosed methods and materials can prove highly valuable in many technological applications including, for instance, in formation of heat management materials for protective clothing and as may be useful in space exploration or in others that require efficient yet light-weight and flexible thermal management solutions.

    Seng, Gary T.

    1991-03-01

    In recent years, the aerospace propulsion and space power communities have acknowledged a growing need for electronic devices that are capable of sustained high-temperature operation. Aeropropulsion applications for high-temperature electronic devices include engine ground test instrumentation such as multiplexers, analog-to-digital converters, and telemetry systems capable of withstanding hot section engine temperatures in excess of 600 C. Uncooled operation of control and condition monitoring systems in advanced supersonic aircraft would subject the electronics to temperatures in excess of 300 C. Similarly, engine-mounted integrated electronic sensors could reach temperatures which exceed 500 C. In addition to aeronautics, there are many other areas that could benefit from the existence of high-temperature electronic devices. Space applications include power electronic devices for space platforms and satellites. Since power electronics require radiators to shed waste heat, electronic devices that operate at higher temperatures would allow a reduction in radiator size. Terrestrial applications include deep-well drilling instrumentation, high power electronics, and nuclear reactor instrumentation and control. To meet the needs of the applications mentioned previously, the high-temperature electronics (HTE) program at the Lewis Research Center is developing silicon carbide (SiC) as a high-temperature semiconductor material. Research is focused on developing the crystal growth, growth modeling, characterization, and device fabrication technologies necessary to produce a family of SiC devices. Interest in SiC has grown dramatically in recent years due to solid advances in the technology. Much research remains to be performed, but SiC appears ready to emerge as a useful semiconductor material.

  11. High Pressure Biomass Gasification

    Energy Technology Data Exchange (ETDEWEB)

    Agrawal, Pradeep K

    2016-07-29

    According to the Billion Ton Report, the U.S. has a large supply of biomass available that can supplement fossil fuels for producing chemicals and transportation fuels. Agricultural waste, forest residue, and energy crops offer potential benefits: renewable feedstock, zero to low CO2 emissions depending on the specific source, and domestic supply availability. Biomass can be converted into chemicals and fuels using one of several approaches: (i) biological platform converts corn into ethanol by using depolymerization of cellulose to form sugars followed by fermentation, (ii) low-temperature pyrolysis to obtain bio-oils which must be treated to reduce oxygen content via HDO hydrodeoxygenation), and (iii) high temperature pyrolysis to produce syngas (CO + H2). This last approach consists of producing syngas using the thermal platform which can be used to produce a variety of chemicals and fuels. The goal of this project was to develop an improved understanding of the gasification of biomass at high pressure conditions and how various gasification parameters might affect the gasification behavior. Since most downstream applications of synags conversion (e.g., alcohol synthesis, Fischer-Tropsch synthesis etc) involve utilizing high pressure catalytic processes, there is an interest in carrying out the biomass gasification at high pressure which can potentially reduce the gasifier size and subsequent downstream cleaning processes. It is traditionally accepted that high pressure should increase the gasification rates (kinetic effect). There is also precedence from coal gasification literature from the 1970s that high pressure gasification would be a beneficial route to consider. Traditional approach of using thermogravimetric analyzer (TGA) or high-pressure themogravimetric analyzer (PTGA) worked well in understanding the gasification kinetics of coal gasification which was useful in designing high pressure coal gasification processes. However, similar approach for

  14. High Pressure Biomass Gasification

    Energy Technology Data Exchange (ETDEWEB)

    Agrawal, Pradeep K [Georgia Tech Research Corporation, Atlanta, GA (United States)

    2016-07-29

    According to the Billion Ton Report, the U.S. has a large supply of biomass available that can supplement fossil fuels for producing chemicals and transportation fuels. Agricultural waste, forest residue, and energy crops offer potential benefits: renewable feedstock, zero to low CO2 emissions depending on the specific source, and domestic supply availability. Biomass can be converted into chemicals and fuels using one of several approaches: (i) biological platform converts corn into ethanol by using depolymerization of cellulose to form sugars followed by fermentation, (ii) low-temperature pyrolysis to obtain bio-oils which must be treated to reduce oxygen content via HDO hydrodeoxygenation), and (iii) high temperature pyrolysis to produce syngas (CO + H2). This last approach consists of producing syngas using the thermal platform which can be used to produce a variety of chemicals and fuels. The goal of this project was to develop an improved understanding of the gasification of biomass at high pressure conditions and how various gasification parameters might affect the gasification behavior. Since most downstream applications of synags conversion (e.g., alcohol synthesis, Fischer-Tropsch synthesis etc) involve utilizing high pressure catalytic processes, there is an interest in carrying out the biomass gasification at high pressure which can potentially reduce the gasifier size and subsequent downstream cleaning processes. It is traditionally accepted that high pressure should increase the gasification rates (kinetic effect). There is also precedence from coal gasification literature from the 1970s that high pressure gasification would be a beneficial route to consider. Traditional approach of using thermogravimetric analyzer (TGA) or high-pressure themogravimetric analyzer (PTGA) worked well in understanding the gasification kinetics of coal gasification which was useful in designing high pressure coal gasification processes. However

    Lerner, Sorin; Kundu, Sudipta

    2011-01-01

    Given the growing size and heterogeneity of Systems on Chip (SOC), the design process from initial specification to chip fabrication has become increasingly complex. This growing complexity provides incentive for designers to use high-level languages such as C, SystemC, and SystemVerilog for system-level design. While a major goal of these high-level languages is to enable verification at a higher level of abstraction, allowing early exploration of system-level designs, the focus so far for validation purposes has been on traditional testing techniques such as random testing and scenario-based

  17. High Performance FORTRAN

    Science.gov (United States)

    Mehrotra, Piyush

    1994-01-01

    High performance FORTRAN is a set of extensions for FORTRAN 90 designed to allow specification of data parallel algorithms. The programmer annotates the program with distribution directives to specify the desired layout of data. The underlying programming model provides a global name space and a single thread of control. Explicitly parallel constructs allow the expression of fairly controlled forms of parallelism in particular data parallelism. Thus the code is specified in a high level portable manner with no explicit tasking or communication statements. The goal is to allow architecture specific compilers to generate efficient code for a wide variety of architectures including SIMD, MIMD shared and distributed memory machines.

  9. High availability using virtualization

    CERN Document Server

    Calzolari, Federico

    2009-01-01

    High availability has always been one of the main problems for a data center. Till now high availability was achieved by host per host redundancy, a highly expensive method in terms of hardware and human costs. A new approach to the problem can be offered by virtualization. Using virtualization, it is possible to achieve a redundancy system for all the services running on a data center. This new approach to high availability allows to share the running virtual machines over the servers up and running, by exploiting the features of the virtualization layer: start, stop and move virtual machines between physical hosts. The system (3RC) is based on a finite state machine with hysteresis, providing the possibility to restart each virtual machine over any physical host, or reinstall it from scratch. A complete infrastructure has been developed to install operating system and middleware in a few minutes. To virtualize the main servers of a data center, a new procedure has been developed to migrate physical to virtu...

    2013-12-01

    Full Text Available The microscopic composition and properties of matter at super-saturation densities have been the subject of intense investigation for decades. The scarcity of experimental and observational data has led to the necessary reliance on theoretical models. There remains great uncertainty in these models which, of necessity, have to go beyond the over-simple assumption that high density matter consists only of nucleons and leptons. Heavy strange baryons, mesons and quark matter in different forms and phases have to be included to fulfil basic requirements of fundamental laws of physics. In this contribution latest developments in construction of the Equation of State (EoS of high-density matter at zero and finite temperature assuming different composition of matter will be discussed. Critical comparison of model EoS with available experimental data from heavy ion collisions and observations on neutron stars, including gravitational mass, radii and cooling patterns and data on X-ray burst sources and low mass X-ray binaries are made. Fundamental differences between the EoS of low-density, high temperature matter, such as is created in heavy ion collisions and of high-density, low temperature compact objects is discussed.

  8. High Selectivity Oxygen Delignification

    Energy Technology Data Exchange (ETDEWEB)

    Arthur J. Ragauskas

    2005-09-30

    The overall objective of this program was to develop improved extended oxygen delignification (EOD) technologies for current U.S. pulp mill operations. This was accomplished by: (1) Identifying pulping conditions that optimize O and OO performance; (2) Identifying structural features of lignin that enhance reactivity towards EOD of high kappa pulps; (3) Identifying factors minimizing carbohydrate degradation and improve pulp strength of EOD high kappa pulps; (4) Developing a simple, reproducible method of quantifying yield gains from EOD; and (5) Developing process conditions that significantly reduce the capital requirements of EOD while optimizing the yield benefits. Key research outcomes included, demonstrating the use of a mini-O sequence such as (E+O)Dkf:0.05(E+O) or Dkf:0.05(E+O)(E+O) without interstage washing could capture approximately 60% of the delignification efficiency of a conventional O-stage without the major capital requirements associated with an O-stage for conventional SW kraft pulps. The rate of formation and loss of fiber charge during an O-stage stage can be employed to maximize net fiber charge. Optimal fiber charge development and delignification are two independent parameters and do not parallel each other. It is possible to utilize an O-stage to enhance overall cellulosic fiber charge of low and high kappa SW kraft pulps which is beneficial for physical strength properties. The application of NIR and multi-variant analysis was developed into a rapid and simple method of determining the yield of pulp from an oxygen delignification stage that has real-world mill applications. A focus point of this program was the demonstration that Kraft pulping conditions and oxygen delignification of high and low-kappa SW and HW pulps are intimately related. Improved physical pulp properties and yield can be delivered by controlling the H-factor and active alkali charge. Low AA softwood kraft pulp with a kappa number 30 has an average improvement of 2% in

    2015-04-01

    This contribution describes the preliminary result of annual cooperation of three student research groups from AGH UST in Krakow, Poland. The aim of this cooperation was to develop and construct a high voltage seismic wave generator. Constructed device uses a high-energy electrical discharge to generate seismic wave in ground. This type of device can be applied in several different methods of seismic measurement, but because of its limited power it is mainly dedicated for engineering geophysics. The source operates on a basic physical principles. The energy is stored in capacitor bank, which is charged by two stage low to high voltage converter. Stored energy is then released in very short time through high voltage thyristor in spark gap. The whole appliance is powered from li-ion battery and controlled by ATmega microcontroller. It is possible to construct larger and more powerful device. In this contribution the structure of device with technical specifications is resented. As a part of the investigation the prototype was built and series of experiments conducted. System parameter was measured, on this basis specification of elements for the final device were chosen. First stage of the project was successful. It was possible to efficiently generate seismic waves with constructed device. Then the field test was conducted. Spark gap wasplaced in shallowborehole(0.5 m) filled with salt water. Geophones were placed on the ground in straight line. The comparison of signal registered with hammer source and sparker source was made. The results of the test measurements are presented and discussed. Analysis of the collected data shows that characteristic of generated seismic signal is very promising, thus confirms possibility of practical application of the new high voltage generator. The biggest advantage of presented device after signal characteristics is its size which is 0.5 x 0.25 x 0.2 m and weight approximately 7 kg. This features with small li-ion battery makes

  10. High population increase rates.

    Science.gov (United States)

    1991-09-01

    In addition to its economic and ethnic difficulties, the USSR faces several pressing demographic problems, including high population increase rates in several of its constituent republics. It has now become clear that although the country's rigid centralized planning succeeded in covering the basic needs of people, it did not lead to welfare growth. Since the 1970s, the Soviet economy has remained sluggish, which as led to increase in the death and birth rates. Furthermore, the ideology that held that demography could be entirely controlled by the country's political and economic system is contradicted by current Soviet reality, which shows that religion and ethnicity also play a significant role in demographic dynamics. Currently, Soviet republics fall under 2 categories--areas with high or low natural population increase rates. Republics with low rates consist of Christian populations (Armenia, Moldavia, Georgia, Byelorussia, Russia, Lithuania, Estonia, Latvia, Ukraine), while republics with high rates are Muslim (Tadzhikistan, Uzbekistan, Turkmenistan, Kirgizia, Azerbaijan Kazakhstan). The later group has natural increase rates as high as 3.3%. Although the USSR as a whole is not considered a developing country, the later group of republics fit the description of the UNFPA's priority list. Another serious demographic issue facing the USSR is its extremely high rate of abortion. This is especially true in the republics of low birth rates, where up to 60% of all pregnancies are terminated by induced abortions. Up to 1/5 of the USSR's annual health care budget is spent on clinical abortions -- money which could be better spent on the production of contraceptives. Along with the recent political and economic changes, the USSR is now eager to deal with its demographic problems. PMID:12284289

  11. High voltage pulse generator

    Science.gov (United States)

    Fasching, George E.

    1977-03-08

    An improved high-voltage pulse generator has been provided which is especially useful in ultrasonic testing of rock core samples. An N number of capacitors are charged in parallel to V volts and at the proper instance are coupled in series to produce a high-voltage pulse of N times V volts. Rapid switching of the capacitors from the paralleled charging configuration to the series discharging configuration is accomplished by using silicon-controlled rectifiers which are chain self-triggered following the initial triggering of a first one of the rectifiers connected between the first and second of the plurality of charging capacitors. A timing and triggering circuit is provided to properly synchronize triggering pulses to the first SCR at a time when the charging voltage is not being applied to the parallel-connected charging capacitors. Alternate circuits are provided for controlling the application of the charging voltage from a charging circuit to be applied to the parallel capacitors which provides a selection of at least two different intervals in which the charging voltage is turned "off" to allow the SCR's connecting the capacitors in series to turn "off" before recharging begins. The high-voltage pulse-generating circuit including the N capacitors and corresponding SCR's which connect the capacitors in series when triggered "on" further includes diodes and series-connected inductors between the parallel-connected charging capacitors which allow sufficiently fast charging of the capacitors for a high pulse repetition rate and yet allow considerable control of the decay time of the high-voltage pulses from the pulse-generating circuit.

  13. Desulfurization at high temperatures

    Energy Technology Data Exchange (ETDEWEB)

    Panula-Nikkilae, E.; Kurkela, E.; Mojtahedi, W.

    1987-01-01

    Two high-temperature desulfurization methods, furnace injection and gasification-desulfurization are presented. In furnace injection, the efficiency of desulfurization is 50-60%, but this method is applied in energy production plants, where flue gas desulfurization cannot be used. Ca-based sorbents are used as desulfurization material. Factors affecting desulfurization and the effect of injection on the boiler and ash handling are discussed. In energy production based on gasification, very low sulfur emissions can be achieved by conventional low-temperature cleanup. However, high-temperature gas cleaning leads to higher efficiency and can be applied to smaller size classes. Ca-, Fe-, or Zn-based sorbents or mixed metals can be used for desulfurization. Most of the methods under development are based on the use of regenerative sorbents in a cleanup reactor located outside the gasifier. So far, only calcium compounds have been used for desulfurization inside the gasifier.

    Clatterbuck, C. H.; Ruitberg, A. P. (Inventor)

    1985-01-01

    A high voltage isolation transformer is provided with primary and secondary coils separated by discrete electrostatic shields from the surfaces of insulating spools on which the coils are wound. The electrostatic shields are formed by coatings of a compound with a low electrical conductivity which completely encase the coils and adhere to the surfaces of the insulating spools adjacent to the coils. Coatings of the compound also line axial bores of the spools, thereby forming electrostatic shields separating the spools from legs of a ferromagnetic core extending through the bores. The transformer is able to isolate a high constant potential applied to one of its coils, without the occurrence of sparking or corona, by coupling the coatings, lining the axial bores to the ferromagnetic core and by coupling one terminal of each coil to the respective coating encasing the coil.

    A pendulum powered by high voltage electricity is described. The pendulum consists of two conducting plates(thin foil) separated by copper rods and are insulated from each other. High voltage is applied to these plates through the connecting copper rods. Another stationary aluminum plate(thin foil) is placed in front of the pendulum such that it serves to attract the pendulum plates and makes electrical contact with them enabling charge transfer between the stationary plate and the pendulum plates. The pendulum is powered by the energy stored in the capacitance between the stationary aluminum plate and the pendulum plate. Attempt has been made to obtain the time period of oscillations as a function of applied voltage and other parameters. The derived formula for the time period has been verified experimentally. This apparatus can be used to demonstrate electrical phenomena in general and in particular electrical energy stored in conductors of small dimensions.

    The ISAC post accelerator comprises an RFQ, DTL and SC-linac. The high energy beam lines connect the linear accelerators as well as deliver the accelerated beams to two different experimental areas. The medium energy beam transport (MEBT) line connects the RFQ to the DTL. The high energy beam transport (HEBT) line connects the DTL to the ISAC-I experimental stations (DRAGON, TUDA-I, GPS). The DTL to superconducting beam (DSB) transport line connects the ISAC-I and ISAC-II linacs. The superconducting energy beam transport (SEBT) line connects the SC linac to the ISAC-II experimental station (TUDA-II, HERACLES, TIGRESS, EMMA and GPS). All these lines have the function of transporting and matching the beams to the downstream sections by manipulating the transverse and longitudinal phase space. They also contain diagnostic devices to measure the beam properties.

  20. Prospects at high energies

    International Nuclear Information System (INIS)

    I discuss some possibilities for neutrino experiments in the fixed-target environment of the SPS, Tevatron, and UNK, with their primary proton beams of 0.4, 0.9, and 3.0 TeV. The emphasis is on unfinished business: issues that have been recognized for some time, but not yet resolved. Then I turn to prospects for proton-proton colliders to explore the 1-TeV scale. I review the motivation for new physics in the neighborhood of 1 TeV and mention some discovery possibilities for high-energy, high-luminosity hadron colliders and the implications they would have for neutrino physics. I raise the possibility of the direct study of neutrino interactions in hadron colliders. I close with a report on the status of the SSC project. 38 refs., 17 figs

    The ability to move 10s of TeraBytes in reasonable amounts of time are critical to many of the High Energy Physics applications.This paper examines the issues of high performance,high reliability tape storage systems,and presents the results of a 2-year ASCI Path Forward program to be able to reliably move 1GB/s to an archive that can last 20 years.This paper will cover the requirements.approach,hardware,application software,interface descriptions,performance,measured reliability and predicted reliability.This paper will also touch on future directions for this research.The current research allows systems to sustain 80MB/s of uncompressable data per Fibre Channel interface which is striped out to 8 or more drives.This looks to the application as a single tape drive from both mout and data transfer perspectives .Striping 12 RAIT systems together will provide nearly 1GB/s to tape.The reliability is provided by a method of adding parity tapes to the data stripes.For example,adding 2 parity tapes to an 8-stripe group will allow any 2 of the 10 tapes to be lost or damaged without loss of information.The reliability of RAIT with 8 stripes and 2 parities exceeds that of mirrored tapes while RAIT uses 10 tapes instead of the 16 tapes that a mirror would require.The results of this paper is to be abloe to understand the applicability of RAIT and to be able to understand when it may be useful in High Energy Physics applications.

    2006-01-01

    Thermal management has become a ‘hot’ field in recent years due to a need to obtain high performance levels in many devices used in such diverse areas as space science, mainframe and desktop computers, optoelectronics and even Formula One racing cars! Thermal solutions require not just taking care of very high thermal flux, but also ‘hot spots’, where the flux densities can exceed 200 W/cm2. High thermal conductivity materials play an important role in addressing thermal management issues. This volume provides readers a basic understanding of the thermal conduction mechanisms in these materials and discusses how the thermal conductivity may be related to their crystal structures as well as microstructures developed as a result of their processing history. The techniques for accurate measurement of these properties on large as well as small scales have been reviewed. Detailed information on the thermal conductivity of diverse materials including aluminum nitride (AlN), silicon carbide (SiC), diamond, a...

  17. High redshift blazars

    CERN Document Server

    Ghisellini, G

    2013-01-01

    Blazars are sources whose jet is pointing to us. Since their jets are relativistic, the flux is greatly amplified in the direction of motion, making blazars the most powerful persistent objects in the Universe. This is true at all frequencies, but especially where their spectrum peaks. Although the spectrum of moderate powerful sources peaks in the ~GeV range, extremely powerful sources at high redshifts peak in the ~MeV band. This implies that the hard X-ray band is the optimal one to find powerful blazars beyond a redshift of ~4. First indications strongly suggest that powerful high-z blazars harbor the most massive and active early black holes, exceeding a billion solar masses. Since for each detected blazars there must exist hundreds of similar, but misaligned, sources, the search for high-z blazars is becoming competitive with the search of early massive black holes using radio-quiet quasars. Finding how the two populations of black holes (one in jetted sources, the other in radio-quiet objects) evolve i...

  18. High power beam analysis

    In various modern scientific and industrial laser applications, beam-shaping optics manipulates the laser spot size and its intensity distribution. However the designed laser spot frequently deviates from the design goal due to real life imperfections and effects, such as: input laser distortions, optical distortion, heating, overall instabilities, and non-linear effects. Lasers provide the ability to accurately deliver large amounts of energy to a target area with very high accuracy. Thus monitoring beam size power and beam location is of high importance for high quality results and repeatability. Depending on the combination of wavelength, beam size and pulse duration , laser energy is absorbed by the material surface, yielding into processes such as cutting, welding, surface treatment, brazing and many other applications. This article will cover the aspect of laser beam measurements, especially at the focal point where it matters the most. A brief introduction to the material processing interactions will be covered, followed by fundamentals of laser beam propagation, novel measurement techniques, actual measurement and brief conclusions.

    Many recuperators have components which react to corrosive gases and are used in applications where the donor fluid includes highly corrosive gases. These recuperators have suffered reduced life, increased service or maintenance, and resulted in increased cost. The present joint when used with recuperators increases the use of ceramic components which do not react to highly corrosive gases. Thus, the present joint used with the present recuperator increases the life, reduces the service and maintenance, and reduces the increased cost associated with corrosive action of components used to manufacture recuperators. The present joint is comprised of a first ceramic member, a second ceramic member, a mechanical locking device having a groove defined in one of the first ceramic member and the second ceramic member. The joint and the mechanical locking device is further comprised of a refractory material disposed in the groove and contacting the first ceramic member and the second ceramic member. The present joint mechanically provides a high strength load bearing joint having good thermal cycling characteristics, good resistance to a corrosive environment and good steady state strength at elevated temperatures.

    This proposal is for the continuation of the High Energy Physics program at the University of California at Riverside. In hadron collider physics the authors will complete their transition from experiment UA1 at CERN to the DZERO experiment at Fermilab. On experiment UA1 their effort will concentrate on data analysis at Riverside. At Fermilab they will coordinate the high voltage system for all detector elements. They will also carry out hardware/software development for the D0 muon detector. The TPC/Two-Gamma experiment has completed its present phase of data-taking after accumulating 160 pb{sup {minus}}1 of luminosity. The UC Riverside group will continue data and physics analysis and make minor hardware improvement for the high luminosity run. The UC Riverside group is participating in design and implementation of the data acquisition system for the OPAL experiment at LEP. Mechanical and electronics construction of the OPAL hadron calorimeter strip readout system is proceeding on schedule. Data analysis and Monte Carlo detector simulation efforts are proceeding in preparation for the first physics run when IEP operation comenses in fall 1989.
