    Fukukura, Jun; Helzer, Erik G; Ferguson, Melissa J

    2013-03-01

    We stand in agreement with Seligman et al. (2013, this issue) that prospection is an important psychological process, but we disagree that it has been neglected within the psychological literature. We further question some of the broader claims made by the authors regarding conscious decision making and free will. We argue that future-oriented cognition is fully consistent with deterministic accounts of cognition, including automaticity, and that prospection does little to advance the position of free will.

    PubMed

    Colligan, R C; Offord, K P; Malinchoc, M; Schulman, P; Seligman, M E

    1994-01-01

    Research based on Seligman's model indicates that a pessimistic explanatory style predicts increased frequency of depression, poorer physical health, and lower levels of achievement. The data show that persons who have a pessimistic outlook on life are more frequent users of the medical and mental health care delivery systems. This paper describes the development of a bipolar MMPI Optimism-Pessimism (PSM) scale that is based on the results of a technique--Content Analysis of Verbatim Explanation (CAVE)--applied to the MMPI. Reliability and validity indices show that the PSM scale is highly accurate and consistent with Seligman's theory. Identification of the patient's explanatory style may lead to improved management because intervention measures can be directed more accurately according to the patient's personality style. The new scale also will allow researchers to use existing MMPI data to explore relationships between explanatory style and various outcome variables and behavioral correlates. PMID:8150997

    Bartos, Karen F.; Ernst, Michael A.

    1993-03-01

    The suitability of the MARC code for the analysis of rotating composite blades was evaluated using a four-task process. A nonlinear displacement analysis and subsequent eigenvalue analysis were performed on a rotating spring mass system to ensure that displacement-dependent centrifugal forces were accounted for in the eigenvalue analysis. Normal modes analyses were conducted on isotropic plates with various degrees of twist to evaluate MARC's ability to handle blade twist. Normal modes analyses were conducted on flat composite plates to validate the newly developed coupled COBSTRAN-MARC methodology. Finally, normal modes analyses were conducted on four composite propfan blades that were designed, analyzed, and fabricated at NASA Lewis Research Center. Results were compared with experimental data. The research documented herein presents MARC as a viable tool for the analysis of rotating composite blades.

  8. Laurance David Hall.

    PubMed

    Coxon, Bruce

    2011-01-01

    An account is given of the life, scientific contributions, and passing of Laurance David Hall (1938-2009), including his early history and education at the University of Bristol, UK, and the synthesis and NMR spectroscopy of carbohydrates and other natural products during ∼20 years of research and teaching at the University of British Columbia in Vancouver, Canada. Lists of graduate students, post-doctoral fellows, and sabbatical visitors are provided for this period. Following a generous endowment by Dr. Herchel Smith, Professor Hall built a new Department of Medicinal Chemistry at Cambridge University, UK, and greatly expanded his researches into the technology and applications of magnetic resonance imaging (MRI) and zero quantum NMR. MRI technology was applied both to medical problems such as the characterization of cartilage degeneration in knee joints, the measurement of ventricular function, lipid localization in animal models of atherosclerosis, paramagnetic metal complexes of polysaccharides as contrast agents, and studies of many other anatomical features, but also to several aspects of materials analysis, including food analyses, process control, and the elucidation of such physical phenomena as the flow of liquids through porous media, defects in concrete, and the visualization of fungal damage to wood. Professor Hall's many publications, patents, lectures, and honors and awards are described, and also his successful effort to keep the Asilomar facility in Pacific Grove, California as the alternating venue for the annual Experimental NMR Conference. Two memorial services for Professor Hall are remembered. PMID:21763510

    2001-06-01

    David Crighton was struck down by cancer in his fifty-eighth year. He was then at the height of his career and was one of the most admired personalities in fluid mechanics. He had specialized in wave theory, helping to understand and solve problems of practical importance using the full power of mathematical method. Efforts to control the sound and vibration caused by unsteady flow were never far from his thinking, and Crighton's contribution to those efforts has changed significantly the way the subject is viewed. Having first attracted him into the field and never losing my interest in the way he was influencing it, it is natural that I should comment on the technical developments while looking back on Crighton's professional life. The subject has changed a great deal and there are now many more researchers involved in its study, many of whom rely on techniques that Crighton pioneered really powerful mathematical methods. But the basic problems remain: powerful flows are noisy.

    2013-06-01

    In the mid-1950s, a new staff member appeared at the Theory Division of the Physical Institute of the Academy of Sciences (FIAN): David Abramovich Kirzhnits. A Moscow State University alumnus, after graduation he had been assigned to a large defense plant in the city of Gorky, where he had worked for several years as an engineer. He was "liberated" from there by Igor Evgenyevich Tamm, our department head, who managed to transfer him to FIAN. Igor Evgenyevich knew D. A. Kirzhnits - they had met in Moscow before Kirzhnits finished university. At that time Kirzhnits was performing thesis work with professor A. S. Kompaneyets as academic adviser. At his adviser's suggestion, D. Kirzhnits consulted with I. E. Tamm on questions pertaining to the thesis topic. I. E. Tamm took a great liking for the diploma student, and he even wanted to recruit D. A. Kirzhnits for the Theory Division immediately after graduation. But at that time (1949) this proved impossible for several reasons. First, D. Kirzhnits was, as they say, an "invalid of the fifth group" - a Jew - which during those years of violent struggle against cosmopolitanismb often proved an obstacle in looking for work. Second, during the years of mass repressions D. Kirzhnits' father had been arrested on treason charges (according to the charges, he had wanted to sell the Far East to Japan). After intensive investigation his father was released, but he lived only a little longer. Reports of this also could have impeded his acceptance. Third, Igor Evgenyevich didn't have enough weight in officials' eyes at that time and so was unable to overcome "first" and "second."...

  14. Nitrite Reductase and Nitric-oxide Synthase Activity of the Mitochondrial Molybdopterin Enzymes mARC1 and mARC2*

    Mitochondrial amidoxime reducing component (mARC) proteins are molybdopterin-containing enzymes of unclear physiological function. Both human isoforms mARC-1 and mARC-2 are able to catalyze the reduction of nitrite when they are in the reduced form. Moreover, our results indicate that mARC can generate nitric oxide (NO) from nitrite when forming an electron transfer chain with NADH, cytochrome b5, and NADH-dependent cytochrome b5 reductase. The rate of NO formation increases almost 3-fold when pH was lowered from 7.5 to 6.5. To determine if nitrite reduction is catalyzed by molybdenum in the active site of mARC-1, we mutated the putative active site cysteine residue (Cys-273), known to coordinate molybdenum binding. NO formation was abolished by the C273A mutation in mARC-1. Supplementation of transformed Escherichia coli with tungsten facilitated the replacement of molybdenum in recombinant mARC-1 and abolished NO formation. Therefore, we conclude that human mARC-1 and mARC-2 are capable of catalyzing reduction of nitrite to NO through reaction with its molybdenum cofactor. Finally, expression of mARC-1 in HEK cells using a lentivirus vector was used to confirm cellular nitrite reduction to NO. A comparison of NO formation profiles between mARC and xanthine oxidase reveals similar Kcat and Vmax values but more sustained NO formation from mARC, possibly because it is not vulnerable to autoinhibition via molybdenum desulfuration. The reduction of nitrite by mARC in the mitochondria may represent a new signaling pathway for NADH-dependent hypoxic NO production. PMID:24500710

    Grape marc (the skins, seeds, stalk, and stems remaining after grapes have been pressed to make wine) is currently a by-product used as a feed supplement by the dairy and beef industries. Grape marc contains condensed tannins and has high concentrations of crude fat; both these substances can reduce enteric methane (CH4) production when fed to ruminants. This experiment examined the effects of dietary supplementation with either dried, pelleted grape marc or ensiled grape marc on yield and composition of milk, enteric CH4 emissions, and ruminal microbiota in dairy cows. Thirty-two Holstein dairy cows in late lactation were offered 1 of 3 diets: a control (CON) diet; a diet containing dried, pelleted grape marc (DGM); and a diet containing ensiled grape marc (EGM). The diet offered to cows in the CON group contained 14.0kg of alfalfa hay dry matter (DM)/d and 4.3kg of concentrate mix DM/d. Diets offered to cows in the DGM and EGM groups contained 9.0kg of alfalfa hay DM/d, 4.3kg of concentrate mix DM/d, and 5.0kg of dried or ensiled grape marc DM/d, respectively. These diets were offered individually to cows for 18d. Individual cow feed intake and milk yield were measured daily and milk composition measured on 4d/wk. Individual cow CH4 emissions were measured by the SF6 tracer technique on 2d at the end of the experiment. Ruminal bacterial, archaeal, fungal, and protozoan communities were quantified on the last day of the experiment. Cows offered the CON, DGM, and EGM diets, ate 95, 98, and 96%, respectively, of the DM offered. The mean milk yield of cows fed the EGM diet was 12.8kg/cow per day and was less than that of cows fed either the CON diet (14.6kg/cow per day) or the DGM diet (15.4kg/cow per day). Feeding DGM and EGM diets was associated with decreased milk fat yields, lower concentrations of saturated fatty acids, and enhanced concentrations of mono- and polyunsaturated fatty acids, in particular cis-9,trans-11 linoleic acid. The mean CH4 emissions were

  5. Processing of SeaMARC swath sonar imagery

    SciTech Connect

    Pratson, L.; Malinverno, A.; Edwards, M.; Ryan, W. )

    1990-05-01

    Side-scan swath sonar systems have become an increasingly important means of mapping the sea floor. Two such systems are the deep-towed, high-resolution SeaMARC I sonar, which has a variable swath width of up to 5 km, and the shallow-towed, lower-resolution SeaMARC II sonar, which has a swath width of 10 km. The sea-floor imagery of acoustic backscatter output by the SeaMARC sonars is analogous to aerial photographs and airborne side-looking radar images of continental topography. Geologic interpretation of the sea-floor imagery is greatly facilitated by image processing. Image processing of the digital backscatter data involves removal of noise by median filtering, spatial filtering to remove sonar scans of anomalous intensity, across-track corrections to remove beam patterns caused by nonuniform response of the sonar transducers to changes in incident angle, and contrast enhancement by histogram equalization to maximize the available dynamic range. Correct geologic interpretation requires submarine structural fabrics to be displayed in their proper locations and orientations. Geographic projection of sea-floor imagery is achieved by merging the enhanced imagery with the sonar vehicle navigation and correcting for vehicle attitude. Co-registration of bathymetry with sonar imagery introduces sea-floor relief and permits the imagery to be displayed in three-dimensional perspectives, furthering the ability of the marine geologist to infer the processes shaping formerly hidden subsea terrains.

    Recently two novel enzymes were identified in the outer mitochondrial membrane, mARC1 and mARC2. These molybdenum containing enzymes can reduce a variety of N-hydroxylated compounds, such as N-hydroxy-guanidines and sulfohydroxamic acids, as well as convert nitrite into nitric oxide (NO). However, their endogenous functions remain unknown. Here we demonstrate a specific developmental pattern of expression of these enzymes. mARC1, but not mARC2, was found to be expressed in fetal human liver, whereas both, in particular mARC2, are abundant in adult liver and also expressed in omental and subcutaneous fat. Caloric diet restriction of obese patients caused a decreased expression of mARC2 in liver, similar to that seen in the livers of starved rats. Knock down of mARC2 expression by siRNA in murine adipocytes had statistically significant effect on the level of diglycerides and on the fatty acid composition of some triglycerides, concomitantly a clear trend toward the reduced formation of most of triglyceride and phospholipid species was observed. The involvement of mARC2 in the metabolism of the hepatotoxic drug ximelagatran was evaluated in hepatocytes and adipocytes. Ximelagatran was shown to cause oxidative stress and knock down of mARC2 in adipocytes prevented ximelagatran induced inhibition of mitochondrial respiration. In conclusion, our data indicate that mARC1 and mARC2 have different developmental expression profiles, and that mARC2 is involved in lipogenesis, is regulated by nutritional status and responsible for activation of ximelagatran into a mitotoxic metabolite(s).

    The Italian spirit obtained from grape marc, grappa, is produced by an extended storage of the marc which allows alcoholic fermentation. Bacterial populations can develop and are associated with off-flavour production. Grape marc acidification before storage is a common practice in distilleries to control bacterial proliferation. Few studies have been published on the microbial biodiversity in grape marc and no information exists about microbiology of acidified marcs and physiological properties needed for colonizing such an environment. The aim of this study was to investigate the composition and dynamics of grape marc bacterial populations during the long-period storage by microbiological analyses of acidified and untreated marcs. Eight bacterial species were identified by ARDRA - 16s rRNA sequencing at the beginning of the fermentation. Among them the bacterial species of Tatumella terrea, Acetobacter ghanensis and Tatumella ptyseos were identified for the first time in a wine environment. In later stages Oenococcus oeni and members of the Lactobacillus plantarum group became dominant in acidified and non-acidified grape marc, respectively. Further molecular typing of L. plantarum isolates yielded 39 strains. To explain the prevalence of L. plantarum in untreated samples, all strains were tested for potential antimicrobial activity and for biofilm formation ability. Although no antimicrobial activity was found, many strains exhibited the ability to form a biofilm, which may confer an ecological advantage to these strains and their dominance during marc storage.

    Within the fields of medicine and sociology, the descriptor "profession" (along with its brethren: profession, professionalization, and professionalism) has had a rich etymological history, with terms taking on different meanings at different times-sometimes trespassing into shibboleth and jargon. This etymological journey has co-evolved with the career of David Mechanic to whom this issue of the Journal of Health Politics, Policy and Law is devoted. We exploit a provocative metaphor applied to Mechanic's work on the challenges facing medicine as a profession as a playful exegesis on what we call "profession" to excavate an ensconced and encrusted domain of health jargon operating at the tensive interface of society and modern medical work.

    We describe the synthesis of a [2]catenane that consists of two triply entwined 114-membered rings, a molecular link. The woven scaffold is a hexameric circular helicate generated by the assembly of six tris(bipyridine) ligands with six iron(II) cations, with the size of the helicate promoted by the use of sulfate counterions. The structure of the ligand extension directs subsequent covalent capture of the catenane by ring-closing olefin metathesis. Confirmation of the Star of David topology (two rings, six crossings) is provided by NMR spectroscopy, mass spectrometry and X-ray crystallography. Extraction of the iron(II) ions with tetrasodium ethylenediaminetetraacetate affords the wholly organic molecular link. The self-assembly of interwoven circular frameworks of controlled size, and their subsequent closure by multiple directed covalent bond-forming reactions, provides a powerful strategy for the synthesis of molecular topologies of ever-increasing complexity.

    While attending medical school at McGill, David Hubel developed an interest in the nervous system during the summers he spent at the Montreal Neurological Institute. After heading to the United States in 1954 for a Neurology year at Johns Hopkins, he was drafted by the army and was assigned to the Neuropsychiatry Division at the Walter Reed Hospital, where he began his career in research and did his first recordings from the visual cortex of sleeping and awake cats. In 1958, he moved to the lab of Stephen Kuffler at Johns Hopkins, where he began a long and fruitful collaboration with Torsten Wiesel. Born in Sweden, Torsten Wiesel began his scientific career at the Karolinska Institute, where he received his medical degree in 1954. After spending a year in Carl Gustaf Bernhard's laboratory doing basic neurophysiological research, he moved to the United States to be a postdoctoral fellow with Stephen Kuffler. It was at Johns Hopkins where he met David Hubel in 1958, and they began working together on exploring the receptive field properties of neurons in the visual cortex. Their collaboration continued until the late seventies. Hubel and Wiesel's work provided fundamental insight into information processing in the visual system and laid the foundation for the field of visual neuroscience. They have had many achievements, including--but not limited to--the discovery of orientation selectivity in visual cortex neurons and the characterization of the columnar organization of visual cortex through their discovery of orientation columns and ocular-dominance columns. Their work earned them the Nobel Prize for Physiology or Medicine in 1981, which they shared with Roger Sperry. PMID:22841302

    David Stanley Evans died on 14 November 2004 in Austin, Texas. He was a noted observational astronomer whose career was divided between South Africa and Texas. He also used the extensive historical collections at the University of Texas to write several books on the history of astronomy. He was born in Cardiff, Wales on 28 January 1916. David received his BA degree in mathematics in 1937 from Kings College, Cambridge. He became a PhD student at Cambridge Observatory in 1937, and was one of Sir Arthur Eddington's last surviving students. He received his PhD degree in 1941 with a dissertation entitled, "The Formation of the Balmer Series of Hydrogen in Stellar Atmospheres." He was a conscientious objector to war and, thus, spent the war years at Oxford working with physicist Kurt Mendelssohn on medical problems, involving cadavers, relating to the war. During these years, David was scientific editor of "Discovery", and he was editor of "The Observatory". David left England in 1946 in order to take up the position of Second Assistant at the Radcliffe Observatory, Pretoria, South Africa. He and H. Knox Shaw were the entire staff after R. O. Redman left, and they aluminized and installed the mirrors in the 74-inch telescope. His notable scientific contribution was to use lunar occultations to measure stellar angular diameters during the 1950s. He succeeded in determining the angular diameter of Antares and determined that Arcturus was not circular but had an elliptical shape. The elliptical shape was later shown to be an instrumental artifact, but the utility of using lunar occultations to measure stellar diameters and stellar multiplicity was conclusively demonstrated. T. Gold presented David's paper on lunar occultation angular diameters at the January 1953 meeting of the Royal Astronomical Society. For the rest of his life, David resented Gold's remarks, because he felt that he had been ridiculed. By 1953, David Evans was Chief Assistant at the Royal Observatory

    Background The aim of this study was to evaluate the effects of Korean Red Ginseng marc with aluminum sulfate as litter amendments on ammonia, soluble reactive phosphorus, and pathogen populations in poultry litters. Methods Increasing levels of Korean Red Ginseng marc with aluminum sulfate were applied onto the surface of rice hull as a top-dress application; untreated rice hulls served as controls. Results: Treatment with Korean Red Ginseng marc with aluminum sulfate or aluminum sulfate alone resulted in lower litter pH (p < 0.05), as compared with that of the controls. There were some differences (p < 0.05) between treatments with Korean Red Ginseng marc with aluminum sulfate or aluminum sulfate alone and controls at 2–4 wk (not at 1 wk). Ammonia levels reduced on an average by 29%, 30%, and 32% for 10 g, 20 g Korean Red Ginseng marc with aluminum sulfate, and aluminum sulfate alone, respectively, as compared with controls at 4 wk. During the experiment, Korean Red Ginseng marc with aluminum sulfate or aluminum sulfate treatment had an effect (p < 0.05) on soluble reactive phosphorus content, as compared with the controls (not at 4 wk). A decrease in Salmonella enterica and Escherichia coli was observed (p < 0.05) in litter amended with both Korean Red Ginseng marc with aluminum sulfate and aluminum sulfate alone, as compared with the control, except at 1–3 wk for Salmonella enterica and 1 wk and 4 wk for Escherichia coli, respectively. Conclusion The results showed that using Korean Red Ginseng marc with aluminum sulfate (blends), which act as acidifying agents by reducing the pH of the litter, was equally effective as aluminum sulfate in reducing the environmental impact.

    2011-11-01

    Vineyard soils in many areas suffer from low organic matter contents, which can be the cause of negative effects such as increasing the risk of erosion, so the use of organic amendments must be considered a good agricultural practice. Even more, if grape marc is recycled as a soil amendment in the vineyards, benefits from a good waste management strategy are also obtained. In the present study, a grape marc from the wine region of Valdeorras (north-west Spain) was used for the production of vermicompost, and this added to a vineyard soil of the same area in a laboratory study. Mixtures of soil and grape marc vermicompost (2 and 4%, dry weight) were incubated for ten weeks at 25°C and the mineralization of C and N studied. The respiration data were fitted to a first-order kinetic model. The rates of grape marc vermicompost which should be added to the vineyard soil in order to maintain the initial levels of organic matter were estimated from the laboratory data, and found to be 1.7 t ha(-1) year(-1) of bulk vermicompost (if the present mean temperature is considered) and 2.1 t ha(-1) year(-1) of bulk vermicompost (if a 2°C increment in temperature is considered), amounts which could be obtained recycling the grape marc produced in the exploitation.

    Global grape production could generate up to 13 Mt/yr of wasted biomass. The compositions of Cabernet Sauvignon (red marc) and Sauvignon Blanc (white marc) were analyzed with a view to using marc as raw material for biofuel production. On a dry weight basis, 31-54% w/w of the grape marc consisted of carbohydrate, of which 47-80% was soluble in aqueous media. Ethanol insoluble residues consisted mainly of polyphenols, pectic polysaccharides, heteroxylans and cellulose. Acid and thermal pre-treatments were investigated for their effects on subsequent cellulose saccharification. A 0.5M sulfuric acid pre-treatment yielded a 10% increase in the amount of liberated glucose after enzymatic saccharification. The theoretical amount of bioethanol that could be produced by fermentation of grape marc was up to 400 L/t. However, bioethanol from only soluble carbohydrates could yield 270 L/t, leaving a polyphenol enriched fraction that may be used in animal feed or as fertilizer. PMID:26117238

    While modulated arc (mARC) capabilities have been available on Siemens linear accelerators for almost two years now, there was, until recently, only one treatment planning system capable of planning these treatments. The Eclipse treatment planning system now offers a module that can plan for mARC treatments. The purpose of this work was to test the module to determine whether it is capable of creating clinically acceptable plans. A total of 23 plans were created for various clinical sites and all plans delivered without anomaly. The average 3%/3 mm gamma pass rate for the plans was 98.0%, with a standard deviation of 1.7%. For a total of 14 plans, an equivalent static gantry IMRT plan was also created to compare delivery time. In all but two cases, the mARC plans delivered significantly faster than the static gantry plan. We have confirmed the successful creation of mARC plans that are deliverable with high fidelity on an ARTISTE linear accelerator, thus demonstrating the successful implementation of the Eclipse mARC module.

    Different winemaking practices are aimed at increasing cell wall degradation to facilitate extraction of valuables molecules into the wine. However, little attention has been paid to the composition of marcs from different cultivars according to the influence of the winemaking procedures. We provide information on skin cell walls from Cabernet Sauvignon, Syrah and Monastrell grapes and examine how different winemaking practices (addition of enzymatic preparation and β-galactosidase separately and dry ice addition) may affect the composition of marc skin cell wall material (CWM). The efficiency of CWM isolation from the grape skin and also its composition is influenced by the cultivar. A similar cultivar influence has been detected on CWM from the marc, being the differences also due to the enological technique. Our results help to increase our knowledge on the degradation of cell walls during vinification, while providing a valuable guideline to upgrade the value of these by-products. PMID:25977002

    At the southwest margin of the Isthmus of Panama, the Cocos, Nazca and Panama Microplate join in a triple junction. In this tectonic setting, the Panama Fracture Zone (PFZ) which bounds the Nazca and Cocos plate, subducts in an oblique and shallow manner. This zone is one of the most active seismic areas of Central America. On July 18, 1934, the largest earthquake in Panama in historical times (Ms= 7.7) occurred in its northern region. This event caused extensive damage to towns located in the border of Panama and Costa Rica and during the two subsequent days, six aftershocks with magnitude greater than 6.0 were recorded. David City, with 130,000 inhabitants is the most important urban center in southwestern Panama and lies at the northern end of the PFZ. This city was impacted by the strong destructive earthquakes (Ms>7.0) that took place in 1879 and 1934, both with epicenters located on the northern terminus of the PFZ. In this work, we collected and digitized historical seismograms to measure the centroid moment tensor (CMT) from the main 1934 earthquake. Additionally, we gathered new macroseismic information to create improved and more complete isoseismals maps of the 1879 and 1934 events. We determined the probabilistic seismic hazard for David City using records of historical and recent seismicity and the characteristics of local faults. The hazard computation results are presented as peak iso-acceleration curves for rock/hard soil for a recurrence time of 500 years. An elastic response spectrum was obtained with a uniform exceedance probability of 10% in 50 years with one degree of freedom and 5% of damping. Our results indicate maximum peak ground acceleration (PGA) in downtown David of 3.8 and 4.5 m/s2 with a probability annual exceedance of 0.002 and 0.001, respectively. Structural vulnerability was determined analyzing the quality and construction design of housing, buildings, and critical facilities as well as the type of soil where these structures

    David Lasser was one of the founders of the American Interplanetary Society (later known as the American Rocket Society) and author of the first English-language book (in 1931) on the use of rockets for human spaceflight. His involvement in the fledgling spaceflight movement was short-lived as he moved on to pursue a distinguished, if turbulent, career in the labor movement. In lieu of an oral history, Mr. Lasser provided his recollections on the pioneering days of rocketry and his thoughts on mankind's destiny in space. This paper provides an overview of Mr. Lasser's life and accomplishments as an American spaceflight visionary, along with a compilation of the information that he graciously provided.

    Thirty years ago, technology companies began nestling their facilities close to academia, and the idea of the university research park was born. Soon after, the concept took off in the field of medicine, and today it's not hard to find such innovation hubs that house biomedical startups drawing on the brainpower of professors and students alike. In late September, the Tucson, Arizona-based Association of University Research Parks--which includes about 170 research parks--announced that David Baker would serve as president of the organization's board of directors for the next year and help guide its strategic goals for the next five years. Baker, who is also the executive director of the University Technology Park at the Illinois Institute of Technology in Chicago, spoke with Roxanne Khamsi about how the organization hopes to branch out and transform these workplaces.

    2013-09-01

    Presents an obituary for David L. Rosenhan (1929-2012). A distinguished psychologist and professor emeritus at Stanford University, Rosenhan died February 6, 2012, at the age of 82, after a long illness. Born in Jersey City, New Jersey, on November 22, 1929, he received a bachelor's degree in mathematics (1951) from Yeshiva College and a master's degree in economics (1953) and a doctorate in psychology (1958) from Columbia University. A professor of law and of psychology at Stanford University from 1971 until his retirement in 1998, Rosenhan was a pioneer in applying psychological methods to the practice of law, including the examination of expert witnesses, jury selection, and jury deliberation. A former president of the American Psychology-Law Society and of the American Board of Forensic Psychology, Rosenhan was a fellow of the American Association for the Advancement of Science, of the American Psychological Association, and of the American Psychological Society. Before joining the Stanford Law School faculty, he was a member of the faculties of Swarthmore College, Princeton University, Haverford College, and the University of Pennsylvania. He also served as a research psychologist at the Educational Testing Service. As generations of Stanford students can attest, David Rosenhan was a spellbinding lecturer who managed to convey the sense that he was speaking to each individual, no matter how large the group. To his graduate students, he was consistently encouraging and optimistic, always ready to share a joke or story, and gently encouraging of their creativity and progressive independence as researchers. The lessons he cared most about offering, in the classroom as in his research, were about human dignity and the need to confront abuse of power and human frailties. PMID:24016118

  9. Vermicomposting grape marc yields high quality organic biofertiliser and bioactive polyphenols.

    Grape is the largest fruit crop in the world, and most (80%) of the harvested fruit is used to make wine. The main by-product of the wine industry is called grape marc, which consists of the stalks, skin, pulp and seeds that remain after pressing the grapes. The aim of this study was to evaluate whether grape marc could be processed by vermicomposting on an industrial scale to yield both a high-quality organic, polyphenol-free fertiliser and grape seeds (as a source of bioactive polyphenols). Vermicomposting reduced the biomass of grape marc substantially (by 58%), mainly as a result of the loss of volatile solids. After 2 weeks, the process yielded a nutrient-rich, microbiologically active and stabilised peat-like material that was easily separated from the seeds by sieving. Although the polyphenol content of the seeds was considerably reduced, this disadvantage was outweighed by the ease of separation of the seeds. Separation of the seeds also eliminated the polyphenol-associated phytotoxicity from the vermicompost. The seeds still contained useful amounts of polyphenols, which could be directly extracted for use in the pharmaceutical, cosmetic and food industries. The procedure described is effective, simple and economical, and could easily be scaled up for industrial application. PMID:25349068

    Highlights: • BioMethane Potential of grape marcs was investigated. • Grape marcs were characterized to realize a micro-scale energy recovery. • Comparative BMP batch-tests utilizing lab-scale reactors were performed. • Biogas valorization by grape marcs anaerobic digestion at small scale is evaluated. - Abstract: The BiochemicalMethanePotential (BMP) of winery organic waste, with reference to two Italian red and white grapes (i.e. Nero Buono and Greco) by-products was investigated. The study was carried out to verify the possibility to reduce the production impact in a green-waste-management-chain-perspective. The possibility to efficiently utilize wine-related-by-products for energy production at a micro-scale (i.e. small-medium scale winery production plant) was also verified. Results showed as a good correlation can be established between the percentage of COD removal and the biogas production, as the winery can produce, from its waste methanization, about 7800 kW h year{sup −1} electrical and 8900 kW h year{sup −1} thermal. A critical evaluation was performed about the possibility to utilize the proposed approach to realize an optimal biomass waste management and an energetic valorization in a local-energy-production-perspective.

    2011-12-01

    David L. Band, of Potomac Maryland, died on March 16, 2009 succumbing to a long battle with spinal cord cancer. His death at the age of 52 came as a shock to his many friends and colleagues in the physics and astronomy community. Band showed an early interest and exceptional aptitude for physics, leading to his acceptance at the Massachusetts Institute of Technology as an undergraduate student in 1975. After graduating from MIT with an undergraduate degree in Physics, Band continued as a graduate student in Physics at Harvard University. His emerging interest in Astrophysics led him to the Astronomy Department at the Harvard Smithsonian Center for Astrophysics (CfA), where he did his dissertation work with Jonathan Grindlay. His dissertation (1985) entitled "Non-thermal Radiation Mechanisms and Processes in SS433 and Active Galactic Nuclei" was "pioneering work on the physics of jets arising from black holes and models for their emission, including self-absorption, which previewed much to come, and even David's own later work on Gamma-ray Bursts," according to Grindlay who remained a personal friend and colleague of Band's. Following graduate school, Band held postdoctoral positions at the Lawrence Livermore Laboratory, the University of California at Berkeley and the Center for Astronomy and Space Sciences at the University of California San Diego where he worked on the BATSE experiment that was part of the Compton Gamma Ray Observatory (CGRO), launched in 1991. BATSE had as its main objective the study of cosmic gamma-ray bursts (GRBs) and made significant advances in this area of research. Band became a world-renowned figure in the emerging field of GRB studies. He is best known for his widely-used analytic form of gamma-ray burst spectra known as the "Band Function." After the CGRO mission ended, Band moved to the Los Alamos National Laboratory where he worked mainly on classified research but continued to work on GRB energetics and spectra. When NASA planned

    2009-12-01

    David J. Hofmann, a pioneer in stratospheric aerosol and ozone research, passed away in Boulder, Colo., on 11 August 2009. He was 72. Dave, a frequent contributor to AGU publications and meetings, was elected an AGU Fellow in 2006. His long and prolific scientific career was, as he would say, simple in concept: Make a long-term commitment to specific measurements, pay attention to the details, and focus on the important issues that the measurements raise. This is simple in concept yet challenging to maintain in a world of short-term contracts and budgets. That Dave sustained and led key measurement programs through 25 years at the University of Wyoming (UW), in Laramie, and 17 years with the U.S. National Oceanic and Atmospheric Administration's (NOAA) Climate Monitoring and Diagnostics Laboratory (CMDL, which became the Global Monitoring Division (GMD) of NOAA's Earth System Research Laboratory) in Boulder, speaks volumes about the scientific and societal benefits that have resulted from his work. Most of the measurement programs he initiated, and the instruments he helped develop for them, continue today as testament to the value of his focus and lasting influence.

    2015-10-01

    The early embryo and periconceptional period is a window during which environmental factors may cause permanent change in the pattern and characteristics of development leading to risk of adult onset disease. This has now been demonstrated across small and large animal models and also in the human. Most evidence of periconceptional 'programming' has emerged from maternal nutritional models but also other in vivo and in vitro conditions including assisted reproductive treatments, show consistent outcomes. This short review first reports on the range of environmental in vivo and in vitro periconceptional models and resulting long-term outcomes. Second, it uses the rodent maternal low protein diet model restricted to the preimplantation period and considers the stepwise maternal-embryonic dialogue that comprises the induction of programming. This dialogue leads to cellular and epigenetic responses by the embryo, mainly identified in the extra-embryonic cell lineages, and underpins an apparently permanent change in the growth trajectory during pregnancy and associates with increased cardiometabolic and behavioural disease in adulthood. We recognize the important advice of David Barker some years ago to investigate the sensitivity of the early embryo to developmental programming, an insight for which we are grateful. PMID:25952250

    2007-07-01

    A new data analysis software is presented that has been developed for the retrieval of atmospheric minor constituents from limb-sounding observations made in the millimeter and sub-millimeter spectral regions. The code, which is called MARC (Millimetre-wave Atmospheric-Retrieval Code), has been designed to analyze the observations of the MARSCHALS (Millimetre-wave Airborne Receivers for Spectroscopic CHaracterisation in Atmospheric Limb-Sounding) instrument which operates on the M-55 stratospheric aircraft. The main objective of the analysis of MARSCHALS observations will be to assess long-wave measurement capabilities for the study of the upper troposphere and lower stratosphere regions. The key questions will be the accuracy and spatial resolution that can be achieved by long-wave measurements in presence of clouds and horizontal gradients. MARC performs a global-fit multi-target retrieval, in which optimal estimation is used and errors of the forward model parameters are taken into account for the definition of the cost function minimized in the retrieval. With these features it is easy to use the variables of the problem as either forward model constant parameters or retrieved unknowns with minimum impact on the stability of the retrieval. MARC can perform a wide spectral-band analysis of the observations without a selection of the analyzed channels, and the retrieval process provides an error budget of the retrieved unknowns that includes both the forward model errors and the measurement errors. The error budget obtained in this way is smaller than that obtained when accounting a posteriori for the systematic errors. The new combination of the retrieval features makes possible an efficient and optimal exploitation of the information content of the observations.

    STS-77 TRAINING VIEW --- Canadian astronaut candidate Marc Garneau, later named as a mission specialist for NASAs STS-77 mission, participates in emergency bailout training at the Johnson Space Center (JSC). Garneau was in the 1992 class of Astronaut Candidates (ascan). Wearing full parachute gear following a simulated parachute drop, Garneau has deployed a small life raft in a 25-feet deep pool in JSCs Weightless Environment Training Facility (WET-F). This portion of an astronauts training is to prepare him or her for proper measures to take in the event of bailout over water. Garneau is assisted here by one of several SCUBA-equipped divers in the pool.

  12. F-MARC: promoting the prevention and management of sudden cardiac arrest in football.

    Sudden cardiac death is the most common cause of unnatural death in football. To prevent and urgently manage sudden cardiac arrest on the football field-of-play, F-MARC (FIFA Medical and Research Centre) has been fully committed to a programme of research, education, standardisation and practical implementation. This strategy has detected football players at medical risk during mandatory precompetition medical assessments. Additionally, FIFA has (1) sponsored internationally accepted guidelines for the interpretation of an athlete's ECG, (2) developed field-of-play-specific protocols for the recognition, response, resuscitation and removal of a football player having sudden cardiac arrest and (3) introduced and distributed the FIFA medical emergency bag which has already resulted in the successful resuscitation of a football player who had a sudden cardiac arrest on the field-of-play. Recently FIFA, in association with the Institute of Sports and Preventive Medicine in Saarbrücken, Germany, established a worldwide Sudden Death Registry with a view to documenting fatal events on the football field-of-play. These activities by F-MARC are testimony to FIFA's continued commitment to minimising sudden cardiac arrest while playing football. PMID:25878076

    In recent years the potential of using microbes as biotechnological sources of industrially relevant enzymes has stimulated a renewed interest in the exploration of new unconventional habitats like trove of natural biodiversity. In this work, grape marcs was selected as extreme environment because of its limited nutrients, exposure to solar radiation, temperature fluctuations and ethanol. One hundred and eighty non-Saccharomyces yeasts and two hundred and twenty Saccharomyces cerevisiae strains were screened for the production of extracellular amylases, cellulases, lipases, pectinases, proteases and xylanases. Two non-Saccharomyces strains were found effective for the hydrolysis of cellulose and starch while eleven S. cerevisiae isolates were described as proficient pectinase producers. For the first time, thirteen S. cerevisiae strains, potentially able to use starch as the sole carbon source, were reported and their potential amylolytic phenotype was found to be related to a non extracellular alpha-amylase. This study encourages the selection of yeasts isolated from grape marcs as sources of unusual and industrially interesting enzymes for future biotechnological applications. PMID:23508399

  14. Marc Dax and the discovery of the lateralisation of language in the left cerebral hemisphere.

    In 1836, Marc Dax presented a revolutionary conclusion based on both his clinical observations and reports from the literature: the localisation of language in the left hemisphere. Twenty-seven years later, his son, Gustave Dax, extended and enriched his work. Their involvement in 19th century neuropsychology is impressive and recognition should have been considerable. However, according to the vast majority of historians of neurology, neuropsychology and aphasiology, the priority in establishing the dominance of the left brain hemisphere for speech goes to Paul Broca in an undivided way. Is it possible that Marc Dax's and his son, Gustave Dax's works were entirely unknown? Were they known and utterly forgotten? Were they ignored? How did we get to know that they existed? The aim of the present paper is to try to answer those and other questions and to demonstrate that there is abundance of data pointing out that the priority of the discovery of left hemisphere dominance for speech ought to be, at least, shared by Dax and Broca.

He will be long remembered for his seminal contributions to the weather satellite program. A pioneer in the use of satellite sensors to provide observations of the Earth's environment for application to weather forecasting and atmospheric science, Dr. Wark was noted for his brilliant insights, dedication, and exceptional scientific achievements. He developed many of the theoretical and experimental techniques on which NOAA's current multi- billion-dollar meteorological satellite program is based. In the 1960's and early 1970's, he and his NOAA colleague Donald Hilleary were the motivating force and principal investigators for the first satellite instruments dedicated to sounding the atmosphere for temperature and water-vapor. These instruments included the Satellite Infra-Red Spectrometer (SIRS)-A and -B and the Vertical Temperature Profile Radiometer (VTPR), which were flown on NASA's Nimbus satellites and NOAA's ITOS-D satellites, respectively. With colleague Henry Fleming, he formulated the radiative transfer equation that quantifies the spectral radiances of the Earth and its atmosphere (measured at satellite altitude) and inverted that equation mathematically to infer the atmospheric temperature profile from satellite-based measurements of those radiances. A difficulty they had to overcome was that the mathematical problem is ill-posed, i.e., it admits of an infinite number of solutions. They arrived at a unique solution via an innovative application of a-priori information on the atmospheric state.

    David Fulmer Bender died in San Diego, California, on 13 September 2004, at the age of 91. His heart stopped suddenly while he was dancing. His pioneering work in establishing comprehensive, computer-accessible ephemerides of asteroids and comets found many applications, including the first-ever visit to an asteroid, Gaspra, by an interplanetary spacecraft. Dave was born in Reno, Nevada, on 10 February 1913, to Homer Charles Bender and Susan Bowers Bender. The family moved to Spokane, Washington, while Dave was very young. His father was a civil engineer and a graduate of MIT, who helped design bridges and dams throughout the Northwest, including the Grand Coolie Dam. Dave had a brother, Phillip (now deceased), who was one year younger. Advancing rapidly in the Spokane school system, Dave finished high school when he was 15 years old. At 16 he moved to Pasadena, California, and began his studies at the California Institute of Technology (Caltech). In addition to pursuing his course work, he was active in track and football, a tendency toward physical exercise that stayed with him for the rest of his life. It was probably during these years that Dave heard a lecture by Albert Einstein, as mentioned to colleagues many years later. Dave received a BS degree in physics in 1933, an MS in 1934, and a PhD in 1937, all from Caltech. His dissertation was entitled, "The Index of Refraction of Air in the Photographic Infrared." During his sophomore year he found his way to Pomona College in Claremont, California, where he met his future wife, Elizabeth Boyden at a social gathering. They were married in 1935. Dave's academic career spanned the years from 1937 to 1970, initially at Louisiana State University, Vanderbilt University, and then Fisk. As a life-long pacifist and conscientious objector, Dave served alternate duty during World War II. In 1946 he joined the faculty of the physics department at Whittier College in California, where he became the department chair and

    How deeply honoured I am to have the opportunity to express my thoughts at this delightful celebration of David's achievements, so far, in his remarkable career. I have been asked to center my remarks on David's contributions to the mentoring and professional development of scientists early in their careers. This is a topic that I am more than happy to reflect on, because it gives me the opportunity to recall the exciting period I spent as one of David's postgraduate students at Imperial College in the early 1980s. It also gives me the chance to publicly express my gratitude to David for the opportunities he created for me at that time, as well as for the interest and care he has shown in my career and well-being ever since, as we have met up and exchanged news and ideas around the world: in New Mexico and Colorado, in Cancun, Paris and Trieste, at numerous March Meetings of the American Physical Society and, of course in London, Oxford, and my home town, Champaign-Urbana, location of the University of Illinois. I have been a member of David's circle for 25 years now, and I would like to tell you a little about how this came to be. Not because of what this says about me, but, rather, because of what it tells you about David and the rich generosity of his spirit and effort when it comes to supporting the underdog. I was indeed one such underdog—and that's putting it charitably—when I first met David in September of 1982, not long before the academic year was to begin. I had heard about the exciting circle of physical and mathematical ideas swirling around the spin glass question during the previous year, which I had spent at the University of California's Los Angeles campus, through an opportunity kindly arranged, as it happens, by Sam Edwards. But I was eager to return to the UK for postgraduate studies and to work on spin glasses, so I simply showed up at David's Imperial College office, unannounced (if I remember correctly). And with his characteristic

  2. Geometric corrections on sidescan sonar images based on bathymetry. Application with SeaMARC II and Sea Beam data

    1994-10-01

    Acoustic backscatter images of the seafloor obtained with sidescan sonar systems are displayed most often using a flat bottom assumption. Whenever this assumption is not valid, pixels are mapped incorrectly in the image frame, yielding distorted representations of the seafloor. Here, such distortions are corrected by using an appropriate representation of the relief, as measured by the sonar that collected the acoustic backscatter information. In addition, all spatial filtering operations required in the pixel relocation process take the sonar geometry into account. Examples of the process are provided by data collected in the Northeastern Pacific over Fieberling Guyot with the SeaMARC II bathymetric sidescan sonar system and the Sea Beam multibeam echo-sounder. The nearly complete (90%) Sea Beam bathymetry coverage of the Guyot serves as a reference to quantify the distortions found in the backscatter images and to evaluate the accuracy of the corrections performed with SeaMARC II bathymetry. As a byproduct, the processed SeaMARC II bathymetry and the Sea Beam bathymetry adapted to the SeaMARC II sonar geometry exhibit a 35m mean-square difference over the entire area surveyed.

    2016-04-01

    NMR metabolomics was used to investigate 57 Greek spirits of four indigenous and four international varieties from Macedonia (tsipouro) and Crete (tsikoudia) to establish their authenticity. The metabolic profile of Romeiko, Malvasia, Xinomavro, Sangiovese and Nebbiolo varieties was assessed for the first time. The WET1D sequence was used to improve sensitivity and unveil minor metabolites. PCA was applied to delineate the provenance of samples and associate metabolites with distinct varietal characteristics, such as the acidity of Sangiovese, the overripe grapes harvesting of Romeiko, the intense body of Cabernet Sauvignon, the light body of Xinomavro and the glutamic acid for Malvasia. The migration of Cabernet Sauvignon from north Greece to Crete was framed. Monitoring multi-varietal spirits introduced 2-vinylethanol as a marker for yeast selection. OPLS-DA was applied to samples from the same vineyard, thus highlighting genotypic markers. Consequently, the findings address the concepts of typicity and traceability in grape marc spirits.

    The Earth's surface beneath the oceans may be very similar, in terms of ambient pressures, to the surface of Venus. For that reason it is particularly important for geologists studying the surface of Venus to understand the processes which form features on the floors of the oceans. With the SeaMARC 2 seafloor mapping system, it is possible to view a swath of seafloor that is 10 km wide (about 6.2 mi). Side scan images of the Mariana region show that volcanoes of the island arc are more complicated than previously realized and that features of the fore-arc region, which resemble volcanoes morphologically, may result from processes other than volcanism. By comparing data obtained from the ocean floor with radar images of Venus, the geological evolution of that planet may be more fully understood.

  7. Inhibition of highly pathogenic PRRSV replication in MARC-145 cells by artificial microRNAs

    PubMed Central

    2011-01-01

    Background Highly pathogenic porcine reproductive and respiratory syndrome (HP-PRRS) has caused large economic losses in swine industry in recent years. However, current antiviral strategy could not effectively prevent and control this disease. In this research, five artificial microRNAs (amiRNAs) respectively targeted towards ORF5 (amirGP5-243, -370) and ORF6 (amirM-82, -217,-263) were designed and incorporated into a miRNA-based vector that mimics the backbone of murine miR-155 and permits high expression of amiRNAs in a GFP fused form mediated by RNA Pol II promoter CMV. Results It was found that amirGP5-370 could effectively inhibit H-PRRSV replication. The amirM-263-M-263, which was a dual pre-amiRNA expression cassette where two amirM-263s were chained, showed stronger virus inhibitory effects than single amirM-263. H-PRRSV replication was inhibited up to 120 hours in the MARC-145 cells which were stably transduced by recombinant lentiviruses (Lenti-amirGP5-370, -amirM-263-M-263). Additionally, efficacious dose of amirGP5-370 and amirM-263 expression did not trigger the innate interferon response. Conclusions Our study is the first attempt to suppress H-PRRSV replication in MARC-145 cells through vector-based and lentiviral mediated amiRNAs targeting GP5 or M proteins coding sequences of PRRSV, which indicated that artificial microRNAs and recombinant lentiviruses might be applied to be a new potent anti-PRRSV strategy.

    Three male F{sub 1} hybrids between Pere David`s deer and red deer were mated to red deer to produce 143 backcross calves. The pedigrees are a rare example of a fertile hybrid between evolutionarily divergent species. We examined the use of these families for genetic mapping of evolutionarily conserved (Type I) loci by testing for genetic linkage between five species-specific protein variants and 12 conserved DNA probes. Two probes were homologous, and the remainder syntenic, to the protein coding loci in cattle or humans. Using six restriction enzymes, each DNA probe detected one or more restriction fragments specific to Pere David`s deer. Linkage analyses among the species-specific variants placed the loci into four linkage groups within which linkage between adjacent loci and gene order was supported by a LOD > 3. Southern and protein analysis of LDHA and ALB provided identical segregation data. These linkage groups were consistent with the cattle gene map and provide new information for comparing the gene maps of ruminants, humans and mice. The deer hybrids are an important new resource that can contribute to the comparative analysis of the mammalian genome. 68 refs., 2 figs., 2 tabs.

  10. DAVID: A new video motion sensor for outdoor perimeter applications

    SciTech Connect

    Alexander, J.C.

    1986-01-01

    To be effective, a perimeter intrusion detection system must comprise both sensor and rapid assessment components. The use of closed circuit television (CCTV) to provide the rapid assessment capability, makes possible the use of video motion detection (VMD) processing as a system sensor component. Despite it's conceptual appeal, video motion detection has not been widely used in outdoor perimeter systems because of an inability to discriminate between genuine intrusions and numerous environmental effects such as cloud shadows, wind motion, reflections, precipitation, etc. The result has been an unacceptably high false alarm rate and operator work-load. DAVID (Digital Automatic Video Intrusion Detector) utilizes new digital signal processing techniques to achieve a dramatic improvement in discrimination performance thereby making video motion detection practical for outdoor applications. This paper begins with a discussion of the key considerations in implementing an outdoor video intrusion detection system, followed by a description of the DAVID design in light of these considerations.

    Israel is a small country with a population of around 7 million. The sole EMS provider for Israel is Magen David Adom (MDA) (translated as 'Red Shield of David'). MDA also carries out the functions of a National Society (similar to the Red Cross) and provides all the blood and blood product services for the country. Nationwide, the organisation responds to over 1000 emergency calls a day and uses doctors, paramedics, emergency medical technicians and volunteers. Local geopolitics has meant that MDA has to be prepared for anything from everyday emergency calls to suicide bombings and regional wars. MDA also prides itself in being able to rapidly assemble and dispatch mobile aid teams to scenes of international disasters. Such a broad range of activities is unusual for a single EMS organisation.

  15. Evaluation of direct phloroglucinolysis and colorimetric depolymerization assays and their applicability for determining condensed tannins in grape marc.

    2015-11-18

    To determine the optimum methods for determining condensed tannin (CT) content in grape marc, butanol-hydrochloric acid assays and phloroglucinolysis were adapted for use, applied to a range of grape marc types, and the methods compared. Porter's assay (butanol-HCl) was found to give unreliable results due to nonlinear color responses to grape skin and seed tannin concentrations, whereas the modification to include acetone (Grabber's assay) overcame this. Differences between skin and seed tannin responses highlighted the need to adequately select the correct grape tannin standard, and the formation of pH-dependent color was accounted for through acidification of blank samples. For phloroglucinolysis, the inability to remove highly bound tannins from cell wall material was highlighted, although a measure of tannins remaining post-phloroglucinolysis (Grabber's assay) showed a trend with the level of exposure to oxidative storage or processing conditions. The comparison of CT concentrations from phloroglucinolysis and Grabber's assay gave poor correlation coefficients. PMID:26551987

    The effects of acoustic energy density (6.8-47.4 W/L) and temperature (20-50 °C) on the extraction yields of total phenolics and tartaric esters during ultrasound-assisted extraction from grape marc were investigated in this study. The ultrasound treatment was performed in a 25-kHz ultrasound bath system and the 50% aqueous ethanol was used as the solvent. The initial extraction rate and final extraction yield increased with the increase of acoustic energy density and temperature. The two site kinetic model was used to simulate the kinetics of extraction process and the diffusion model based on the Fick's second law was employed to determine the effective diffusion coefficient of phenolics in grape marc. Both models gave satisfactory quality of data fit. The diffusion process was divided into one fast stage and one slow stage and the diffusion coefficients in both stages were calculated. Within the current experimental range, the diffusion coefficients of total phenolics and tartaric esters for both diffusion stages increased with acoustic energy density. Meanwhile, the rise of temperature also resulted in the increase of diffusion coefficients of phenolics except the diffusion coefficient of total phenolics in the fast stage, the value of which being the highest at 40 °C. Moreover, an empirical equation was suggested to correlate the effective diffusion coefficient of phenolics in grape marc with acoustic energy density and temperature. In addition, the performance comparison of ultrasound-assisted extraction and convention methods demonstrates that ultrasound is an effective and promising technology to extract bioactive substances from grape marc.

  17. A Staged Reading of the Play: TRANSCENDENCE: Relativity and Its Discontents by Robert Marc Friedman

    Friedman, Robert Marc

    2015-04-01

    TRANSCENDENCE explores aspects of Einstein's life and his general theory of relativity at the time of the theory's creation and initial reception. While being faithful to historical scholarship, the play creates its own theatrical reality aiming to engage emotions and intellect. Those who strive for transcendence must nevertheless also confront the harsh realities of living in specific time-bound social contexts. Universal constants that anchor physical theory in an objective reality, as Einstein believed, do not readily have equivalents in notions of identity, duty, loyalty, and excellence. In November 1915 after toiling for years in Zurich, Prague, and now Berlin, Einstein achieved his general theory of relativity. When in 1919 British astronomers announced evidence for the bending of starlight by the sun as Einstein had predicted, he soon surprisingly found himself an international celebrity. Expectations arose that he would be called to Stockholm. But the Nobel Committee for Physics refused to acknowledge ``speculations'' such Einstein's. The dismissal of relativity entailed principled and biased opposition, and not simply mistakes in evaluation. Several committee members agreed that Einstein must not receive a Prize. Join us for a dramatic staged reading of TRANSCENDENCE, a play by the science historian Robert Marc Friedman (http://www.hf.uio.no/iakh/english/people/aca/robertfr/index.html) and directed by James Glossman, Lecturer in Directing and Shakespeare, Johns Hopkins University. After the performance, the playwright, director and actors will be available for a talk-back audience discussion.

  18. Improving green waste composting by addition of sugarcane bagasse and exhausted grape marc.

    Zhang, Lu; Sun, Xiangyang

    2016-10-01

    The composting of lignocellulosic waste into compost is a potential way of sustainably disposing of a waste while generating a useful product. The current study determined whether the addition of sugarcane bagasse (SCB) (at 0, 15, and 25%) and/or exhausted grape marc (EGM) (at 0, 10, and 20%) improved the two-stage composting of green waste (GW). The combined addition of SCB and EGM improved composting conditions and the quality of the compost product in terms of temperature, water-holding capacity, particle-size distribution, coarseness index, pH, electrical conductivity, water-extractable organic carbon and nitrogen, microbial numbers, enzymatic activities, polysaccharide and lignin content, nutrient content, respiration, and phytotoxicity. The optimal two-stage composting and the best quality compost were obtained with the combined addition of 15% SCB and 20% EGM. With the optimized two-stage composting method, the compost matured in only 21days rather than in the 90-270days required for traditional composting. PMID:27376832

    This work is based on my thesis from Aix en Provence on French Civilisation and Letters (1984). The head of the examinations was the writer Raymond Jean. My idea is to show how the decadent writer and poet Marc André Raffalovich fought against the personalities in science concerning homosexuality with a new point of view and with great difficulty, shedding new light on this subject in a review from 1886 to 1914 under the direction of Dr. Alexandre Lacassagne Les Archives d'Anthropologie Criminelle de Médecine Légale et de Psychologie Normale et Pathologique published in 1886, edited by the director A. Lacassagne, professor and chairman of legal medicine, Lyon, and author of the article "Pederastie," Dictionnaire Encyclopedique des Sciences Medicales, volume XXII published in 1886. In 1893, he wrote an introduction for l'Inversion Sexuelle of Dr. Julien Chevalier (Paris: Masson-Lyon Storck). This monthly review "d'au moins 80 pages" was called L'Ecole Lyonnaise, and so to say, l'Ecole Francaise d'Anthropologie Criminelle, which defends against l'Ecole Italienne of Lombroso, the culturalist theory of the birth of the criminal; according to this école du milieu social: "La Société a les criminels qu'elle merite" (The society has criminals it deserves). After the first world war, it was to be overridden by the Marxist analysis. PMID:8301079

  20. Abner Doubleday, Marc Bloch, and the cultural significance of baseball in rural America.

    PubMed

    Vaught, David

    2011-01-01

    In 1907 baseball's promoters decreed that Civil War hero Abner Doubleday created the game in the village of Cooperstown, New York, in 1839. Baseball thus acquired a distinctly rural American origin and a romantic pastoral appeal. Skeptics have since presented irrefutable evidence that America's pastime was neither born in the United States nor was a product of rural life. But in their zeal to debunk the myth of baseball's rural beginnings, historians have fallen prey to what Annales School founder Marc Bloch famously called the "idol of origins," and all but neglected the very real phenomenon of rural baseball itself. The claim that baseball has always been "a city game for city men" does not stand up to empirical scrutiny anymore than the Doubleday myth itself, as this address demonstrates with three case studies -- Cooperstown in the 1830s, Davisville, California, in the 1880s, and Milroy, Minnesota, in the 1950s. Baseball may have been a source of rural nostalgia for city people, but it was the sport of choice for farmers and a powerful cultural agent. PMID:21313784

  1. SeaMARC II mapping of transform faults in the Cayman Trough, Caribbean Sea

    1992-01-01

    SeaMARC II maps of the southern wall of the Cayman Trough between Honduras and Jamaica show zones of continuous, well-defined fault lineaments adjacent and parallel to the wall, both to the east and west of the Cayman spreading axis. These lineaments mark the present, active traces of transform faults which intersect the southern end of the spreading axis at a triple junction. The Swan Islands transform fault to the west is dominated by two major lineaments that overlap with right-stepping sense across a large push-up ridge beneath the Swan Islands. The fault zone to the east of the axis, named the Walton fault, is more complex, containing multiple fault strands and a large pull-apart structure. The Walton fault links the spreading axis to Jamaican and Hispaniolan strike-slip faults, and it defines the southern boundary of a microplate composed of the eastern Cayman Trough and western Hispaniola. The presence of this microplate raises questions about the veracity of Caribbean plate velocities based primarily on Cayman Trough opening rates.

  2. A finite element analysis modeling tool for solid oxide fuel cell development: coupled electrochemistry, thermal and flow analysis in MARC ®

    NASA Astrophysics Data System (ADS)

    Khaleel, M. A.; Lin, Z.; Singh, P.; Surdoval, W.; Collin, D.

    A 3D simulation tool for modeling solid oxide fuel cells is described. The tool combines the versatility and efficiency of a commercial finite element analysis code, MARC ®, with an in-house developed robust and flexible electrochemical (EC) module. Based upon characteristic parameters obtained experimentally and assigned by the user, the EC module calculates the current density distribution, heat generation, and fuel and oxidant species concentration, taking the temperature profile provided by MARC ® and operating conditions such as the fuel and oxidant flow rate and the total stack output voltage or current as the input. MARC ® performs flow and thermal analyses based on the initial and boundary thermal and flow conditions and the heat generation calculated by the EC module. The main coupling between MARC ® and EC is for MARC ® to supply the temperature field to EC and for EC to give the heat generation profile to MARC ®. The loosely coupled, iterative scheme is advantageous in terms of memory requirement, numerical stability and computational efficiency. The coupling is iterated to self-consistency for a steady-state solution. Sample results for steady states as well as the startup process for stacks with different flow designs are presented to illustrate the modeling capability and numerical performance characteristic of the simulation tool.

    The purpose of this project was to establish a new hyperspectral remote sensing laboratory at the Mid-America Remote sensing Center (MARC), dedicated to in situ and laboratory measurements of environmental samples and to the manipulation, analysis, and storage of remotely sensed data for environmental monitoring and research in ecological modeling using hyperspectral remote sensing at MARC, one of three research facilities of the Center of Reservoir Research at Murray State University (MSU), a Kentucky Commonwealth Center of Excellence. The equipment purchased, a FieldSpec FR portable spectroradiometer and peripherals, and ENVI hyperspectral data processing software, allowed MARC to provide hands-on experience, education, and training for the students of the Department of Geosciences in quantitative remote sensing using hyperspectral data, Geographic Information System (GIS), digital image processing (DIP), computer, geological and geophysical mapping; to provide field support to the researchers and students collecting in situ and laboratory measurements of environmental data; to create a spectral library of the cover types and to establish a World Wide Web server to provide the spectral library to other academic, state and Federal institutions. Much of the research will soon be published in scientific journals. A World Wide Web page has been created at the web site of MARC. Results of this project are grouped in two categories, education and research accomplishments. The Principal Investigator (PI) modified remote sensing and DIP courses to introduce students to ii situ field spectra and laboratory remote sensing studies for environmental monitoring in the region by using the new equipment in the courses. The PI collected in situ measurements using the spectroradiometer for the ER-2 mission to Puerto Rico project for the Moderate Resolution Imaging Spectrometer (MODIS) Airborne Simulator (MAS).

    Shortly after AGU launched its annual voluntary contribution campaign last year—the theme was “Building Tomorrow's Talent Today”—the Union's development office received an e-mail message from David E. Lumley about establishing a scholarship for a high-school student or undergraduate. Many scientific societies and associations have quite a few named scholarships, but for AGU this was a new concept. Lumley was sure of what he wanted to do and even more excited when he learned that his scholarship would be a first for AGU. “I want to help inspire today's young minds to work on problems of global importance in both the energy and environment sectors of industry and academia,” Lumley said. Recipients of the David E. Lumley Young Scientist Scholarship for Energy and Environmental Science will be expected to present a paper and to participate in various student activities at Fall Meeting. “Meeting some of the ‘giants’ of geoscience and getting their feedback on research is a big deal for these young students. We sometimes lose sight of this,” he said.

    SeaMARC IA sidescan sonar images of the distal reaches of a depositional lobe on the Mississippi Fan show that channelized rather than unconfined transport was the dominant transport mechanism for coarse-grained sediment during the formation of this part of the deep-sea fan. Overbank sheet flow of sands was not an important process in the transport and deposition of the sandy and silty sediment found on this fan. The dendritic distributary pattern and the high order of splaying of the channels, only one of which appears to have been active at a time, suggest that coarse-grained deposits on this fan are laterally discontinuous.

    SeaMARC side-scan sonographs and Argo video and photographic data suggest that the recent sedimentary environment of the floor of the Tongue of the Ocean is controlled by an interplay of turbidity current flow from the south, sediment spill-over from the carbonate platform to the east (windward side), and rock falls from the west carbonate escarpment (lee side). The spill-over forms a sandy sedimentary deposit that acts as a topographic obstruction to the turbidity current flow from the south. This obstruction is expressed by the westward migration of a northwest-southeast oriented turbidity-current-cut channel. ?? 1989 Springer-Verlag New York Inc.

    The David L. Lawrence Convention Center is the largest Gold LEED NC (new construction) certified convention center in the USA and the first of its kind in the world. The designation has been awarded by the United States Green Building Council through its Leadership in Energy and Environmental Design (LEED) Green Building Rating System. In this talk we discuss the unique green properties of this 1.5 million square foot Convention Center including the design and use of daylight, natural ventilation and other sustainable design and practices. No other building the size of the Convention Center (1.5 million square feet), uses natural ventilation or can illuminate an exhibition hall entirely through its windows and skylights. Approximately 75% of the convention center's exhibition space is lit by natural daylight. The use of natural ventilation and extensive day lighting is designed to reduce energy consumption by nearly 35% compared to traditional ventilated and lit buildings of a similar size.

    Chandler, A.; Foley, D.; Hafez, A.M.

    2000-01-01

    The purpose of this article is to raise and address a number of issues related to the conversion of Federal Geographic Data Committee metadata into MARC21 and Dublin Core. We present an analysis of 466 FGDC metadata records housed in the National Biological Information Infrastructure (NBII) node of the FGDC Clearinghouse, with special emphasis on the length of fields and the total length of records in this set. One of our contributions is a 34 element crosswalk, a proposal that takes into consideration the constraints of the MARC21 standard as implemented in OCLC's World Cat and the realities of user behavior.

  2. Identification of a new cell line permissive to porcine reproductive and respiratory syndrome virus infection and replication which is phenotypically distinct from MARC-145 cell line

    PubMed Central

    2012-01-01

    Background Airborne transmitted pathogens, such as porcine reproductive and respiratory syndrome virus (PRRSV), need to interact with host cells of the respiratory tract in order to be able to enter and disseminate in the host organism. Pulmonary alveolar macrophages (PAM) and MA104 derived monkey kidney MARC-145 cells are known to be permissive to PRRSV infection and replication and are the most studied cells in the literature. More recently, new cell lines developed to study PRRSV have been genetically modified to make them permissive to the virus. The SJPL cell line origin was initially reported to be epithelial cells of the respiratory tract of swine. Thus, the goal of this study was to determine if SJPL cells could support PRRSV infection and replication in vitro. Results The SJPL cell growth was significantly slower than MARC-145 cell growth. The SJPL cells were found to express the CD151 protein but not the CD163 and neither the sialoadhesin PRRSV receptors. During the course of the present study, the SJPL cells have been reported to be of monkey origin. Nevertheless, SJPL cells were found to be permissive to PRRSV infection and replication even if the development of the cytopathic effect was delayed compared to PRRSV-infected MARC-145 cells. Following PRRSV replication, the amount of infectious viral particles produced in SJPL and MARC-145 infected cells was similar. The SJPL cells allowed the replication of several PRRSV North American strains and were almost efficient as MARC-145 cells for virus isolation. Interestingly, PRRSV is 8 to 16 times more sensitive to IFNα antiviral effect in SJPL cell in comparison to that in MARC-145 cells. PRRSV induced an increase in IFNβ mRNA and no up regulation of IFNα mRNA in both infected cell types. In addition, PRRSV induced an up regulation of IFNγ and TNF-α mRNAs only in infected MARC-145 cells. Conclusions In conclusion, the SJPL cells are permissive to PRRSV. In addition, they are phenotypically different

  7. Sir David Brewster's changing ideas on the plurality of worlds

    NASA Astrophysics Data System (ADS)

    de Asúa, Miguel

    2006-06-01

    In the course of his long life the Scottish physicist David Brewster wrote copiously about the plurality of worlds. More Worlds than One (1854), perhaps his strongest statement on the question, was written as an answer to William Whewell's On the Plurality of Worlds (1853), which argued that life was a privilege of the Earth. Brewster's ideas changed drastically along the years in many crucial issues such as the habitability of the Sun and the Moon, the possibility that extraterrestrials could be different from humans, and the occupation of the Earth by intelligent races in the distant past. This paper succinctly surveys Brewster's main lines of thought about the plurality of worlds underlining the significance of his first two articles devoted exclusively to this topic. They were published in 1838 in The Monthly Chronicle, and affirm the habitability of the planets while denying that of the Moon. As is the case with many Victorian scientists, belief in pluralism was for Brewster part and parcel of a complex of ideas and attitudes in which it is hard to distinguish science from religion. I shall argue that a fair number of the shifting opinions and inconsistencies detectable in Brewster's ideas on the plurality of worlds can be attributed to the fact that these were used as pliable apologetic instruments in his scientific writings, many of which are permeated by strong religious concerns.

  8. David Malament and the Conventionality of Simultaneity: A Reply

    NASA Astrophysics Data System (ADS)

    Grünbaum, Adolf

    2010-10-01

    In 1977, David Malament proved the valuable technical result that the simultaneity relation of standard synchrony ɛ=1/2 with respect to an inertial observer O is uniquely definable in terms of the relation κ of causal connectibility. And he claimed that this definability undermines my own version of the conventionality of metrical simultaneity within an inertial frame. But Malament’s proof depends on the imposition of several supposedly “innocuous” constraints on any candidate for the simultaneity relation relative to O. Relying on Allen I. Janis’s 1983 challenge to one of these constraints, I argue that Malament’s technical result did not undermine my philosophical construal of the ontological status of relative metrical simultaneity. Furthermore, I show that (a) Michael Friedman’s peremptorily substantivalist critique of my conception, which Malament endorses, is ill-founded, and (b) if Malament had succeeded in discrediting my own conventionalist version of metrical simultaneity, he would likewise have invalidated Einstein’s pioneering version of it.

    The U.S. Department of Energy (DOE) Oak Ridge Office (ORO) of Environmental Management (EM) requested the technical assistance of Oak Ridge Institute for Science and Education (ORISE) to characterize a tract of land associated with the David Witherspoon, Incorporated (DWI) Volunteer Equipment and Supply Company (VESC). This tract of land (hereinafter referred to as Screen Arts) is located in the Vestal Community in the 2000-block of Maryville Pike in south Knoxville, Tennessee, as shown in Figure A-1. This tract of land has been used primarily to store salvaged equipment and materials for resale, recycle, or for disposal in the former landfill once operated by DWI. The DWI Site industrial landfill and metal recycling business had been permitted by the Tennessee Division of Radiological Health to accept low-level radiologically contaminated metals. DWI received materials and equipment associated with operations from DOE sites, including those in Oak Ridge, Tennessee; Paducah, Kentucky; and Portsmouth, Ohio. It is likely that items stored at Screen Arts may have contained some residual radiological materials.

  10. Reconstructing apology: David Cameron's Bloody Sunday apology in the press.

    McNeill, Andrew; Lyons, Evanthia; Pehrson, Samuel

    2014-12-01

    While there is an acknowledgement in apology research that political apologies are highly mediated, the process of mediation itself has lacked scrutiny. This article suggests that the idea of reconstruction helps to understand how apologies are mediated and evaluated. David Cameron's apology for Bloody Sunday is examined to see how he constructs four aspects of apology: social actors, consequences, categorization, and reasons. The reconstruction of those aspects by British, Unionist, and Nationalist press along with reconstructions made by soldiers in an online forum are considered. Data analysis was informed by thematic analysis and discourse analysis which helped to explore key aspects of reconstruction and how elements of Cameron's apology are altered in subsequent mediated forms of the apology. These mediated reconstructions of the apology allowed their authors to evaluate the apology in different ways. Thus, in this article, it is suggested that the evaluation of the apology by different groups is preceded by a reconstruction of it in accordance with rhetorical goals. This illuminates the process of mediation and helps to understand divergent responses to political apologies. PMID:24286526

    The comprehensive integration and environmental (including RF) test facilities of the Canadian Space Agency's David Florida Laboratory (CSA)(DFL) were used extensively for the MSAT Program. Following a description of the facilities, the paper outlines their application to the qualification of the two MSAT satellites following an overview of the test plan. Particular emphasis is given to passive intermodulation measurement (PIM) demands, which for the MSAT satellites, contributed to the need to extend the anechoic chamber. The extended chamber was also used for an EMC test and SAR signature test of the RADARSAT satellite. The DFL's facilities are being used for additional aspects of mobile satellite communications. One shielded anechoic Extra High Frequency (EHF) chamber and associated test equipment are employed predominantly for measuring the performance of the IRIDIUM satellites' Engineering Model Gateway Moveable Antennas (EM)(GMA). Other chambers are used for testing aeronautical antennas on behalf of Inmarsat. Still others combine thermal and PIM testing. The paper concludes with a review of the test requirements of evolving satcom missions such as Inmarsat Aero-1.

    Cell apoptosis is common after infection with porcine reproductive and respiratory syndrome virus (PRRSV). PRRSV GP5 has been reported to induce cell apoptosis. To further understand the role of GP5 in PRRSV induced cell apoptosis, we established Marc-145 cell lines stably expressing full-length GP5, GP5{sup Δ84-96} (aa 84-96 deletion), and GP5{sup Δ97-119} (aa 97-119 deletion). Cell proliferation, cell cycle progression, cell apoptosis and virus replication in these cell lines were evaluated. Neither truncated nor full-length GP5 induced cell apoptosis in Marc-145 cells. However, GP5{sup Δ97-119}, but not full-length or GP5{sup Δ84-96}, induced a cell cycle arrest at the G2/M phase resulting in a reduction in the growth of Marc-145 cells. Additionally, GP5{sup Δ84-96} inhibited the replication of PRRSV in Marc-145 cells through induction of IFN-β. These findings suggest that PRRSV GP5 is not responsible for inducing cell apoptosis in Marc-145 cells under these experimental conditions; however it has other important roles in virus/host cell biology. - Highlights: • Marc-145 cell lines stable expression PRRSV GP5 or truncated GP5 were constructed. • GP5{sup Δ97-119} expression in Marc-145 cell induced cell cycle arrest at G2/M phase. • Expression of GP5 and truncated GP5 could not induce Marc-145 cells apoptosis. • PRRSV replication in Marc-145-GP5{sup Δ84-96} was significantly inhibited.

    Despite the powerful impact gene expression markers like the green fluorescent protein (GFP) or enhanced GFP (EGFP) exert on linking the expression of recombinant protein for selection of high producers in recent years, there is still a strong incentive to develop more economical and efficient methods for isolating mammalian cell clones secreting high levels of recombinant proteins. Here we present a new method based on the co-expression of EGFP that allows clonal selection in standard 96-well cell culture plates. The genes encoding the EGFP protein and the related protein are linked by an internal ribosome entry site and thus are transcribed into the same mRNA in an independent translation process. Since both proteins arise from a common mRNA, the EGFP expression level correlates with the expression level of the therapeutic protein in each clone. By expressing recombinant porcine β-defensin 1 in Marc 145 cells, we demonstrate the robustness and performance of this technique. The method can be served as an alternative to identify high-producer clones with various cell sorting methods. PMID:25297006

  16. Phenolic compounds and antioxidant activity of extracts from ultrasonic treatment of Satsuma Mandarin (Citrus unshiu Marc.) peels.

    Ultrasound-assisted extraction (UAE) was used to extract phenolic compounds from Satsuma mandarin ( Citrus unshiu Marc.) peels (SMP), and maceration extraction (ME) was used as a control. The effects of ultrasonic time (10, 20, 30, 40, 50, and 60 min), temperature (15, 30, and 40 degrees C), and ultrasonic power (3.2, 8, 30, and 56 W) on phenolic compounds were investigated. High-performance liquid chromatography (HPLC) coupled with a photodiode array (PDA) detector was used for the analysis of phenolic acids after alkaline hydrolysis (bound phenolic acids) and flavanone glycosides. The contents of seven phenolic acids (caffeic acid, p-coumaric acid, ferulic acid, sinapic acid, protocatechuic acid, p-hydroxybenzoic acid, and vanillic acid) and two flavanone glycosides (narirutin and hesperidin) in extracts obtained by ultrasonic treatment were significantly higher than in extracts obtained by the maceration method. Moreover, the contents of extracts increased as both treatment time and temperature increased. Ultrasonic power had a positive effect on the contents of extracts. However, the phenolic acids may be degraded by ultrasound at higher temperature for a long time. For example, after ultrasonic treatment at 40 degrees C for 20 min, the contents of caffeic acid, p-coumaric acid, ferulic acid, and p-hydroxybenzoic acid decreased by 48.90, 44.20, 48.23, and 35.33%, respectively. The interaction of ultrasonic parameters probably has a complex effect on the extracts. A linear relationship was observed between Trolox equivalent antioxidant capacity (TEAC) values and total phenolic contents (TPC); the correlation coefficient, R(2), is 0.8288 at 15 degrees C, 0.7706 at 30 degrees C, and 0.8626 at 40 degrees C, respectively. The data indicated that SMPs were rich sources of antioxidants. Furthermore, UAE techniques should be carefully used to enhance the yields of phenolic acids from SMPs. PMID:18572916

  17. The paradox of drowned reefs: A Caribbean example mapped using SeaMARC II side-scan sonar

    1990-05-01

    Three models for the drowning of carbonate platforms and associated fringing coral reefs include (1) rapid submergence below the euphotic zone by tectonic subsidence and sea level rise; (2) excess nutrients in the water; and (3) burial by prograding marine siliclastic sediments. To examine these mechanisms on a regional scale, the authors mapped drowned barrier reef tracts around the active carbonate banks of the Nicaraguan Rise using SeaMARC II sidescan sonar, 3.5 KHz, and digital single channel reflection techniques. The reef tracts exhibited high sonar backscatter and were prominently displayed on sidescan images. Characteristic features of the reef tracts include (1) uneroded and slightly sinuous mounds that crop out on the sea floor and closely following bathymetric contours; (2) reef mounds that typically occur in stairstep sets of two to three terraces; (3) water depths at the crest of the reef mounds that range from 1,050 to 1,500 m; and (4) reef mounds that extend for 1,200 km around the base of the slope (depth 1,300 m) of an active carbonate platform in a moderately active, intraplate setting (Pedro Bank) and along the crest of a submerged fault block in a highly active, interplate setting (Bay Islands Ridge, ridge crest depth at 1,600 m). Because these newly discovered reef tracts have not been dredged, their ages and compositions remain unknown. Based on the observed sea floor outcrop, regional extent, and approximate correlation in water depth of the reef tracts, mechanisms 1 and 2 appear to be the most likely drowning mechanisms.

    Boyer, Carol A; Gray, Bradford H

    2016-08-01

    David Mechanic has been a pioneering leader in the social and behavioral sciences of health, health services, and health and mental health policy for more than fifty years. One of David's most distinctive qualities has been his vision in identifying trends and defining new research areas and perspectives in health care policy. His early work on how methods of physician payment by capitation and fee-for-service in England and the United States affected physicians' responses to patients and patient care addressed present challenges and many ongoing studies of payment mechanisms. His papers on rationing of health care established a framework for examining alternative allocation mechanisms and just decision making. Influential papers dealt with risk selection, policy challenges in managed care, reducing racial disparities, trust relationships between patients, doctors, and the public and health institutions, and the predicaments of health reform.

  10. Role of non-structural protein 2 in the regulation of the replication of the porcine reproductive and respiratory syndrome virus in MARC-145 cells: effect of gene silencing and over expression.

    Porcine reproductive and respiratory syndrome (PRRS) is an economically important disease in swine-producing areas. Many vaccine strategies have been developed to control the disease, but none have yet been completely successful. The development of a cell line that can produce large yields of PRRSV vaccine is very necessary. In order to determine the role of Nsp2 in the replication of the highly pathogenic porcine reproductive and respiratory syndrome virus (HP-PRRSV) in MARC-145 cells, we used an RNA interference-based short hairpin RNA of Nsp2 and constructed cell lines expressing the HP-PRRSV Nsp2 gene. Conserved HP-PRRSV Nsp2 sequences were used to design short interfering RNAs and test their ability to silence PRRSV transcript expression and replication in cells in vitro transfection. Nsp2, ORF7, and β-actin mRNA expression were determined using semi-quantitative real-time PCR. Infection with siRNA targeting Nsp2 was found to reduce the Nsp2 expression in MARC-145 cells infected with PRRSV. Both MARC-145-TJ Nsp2 and MARC-145-TJM Nsp2 cell lines were screened by G418, which were infected with HP-PRRSV, normal MARC-145 cells for mock, and then virus titers were calculated by TCID(50) after the CPE showing up. The downregulation of Nsp2 induced a remarkable decrease in PRRSV replication, causing the reduction of structural protein. The Nsp2-targeted siRNA was found to downregulate the expression of Nsp2 in MARC-145 cells and inducing replication reduce of PRRSV in MARC-145 cells. The shRNA vectors S-1 and S-2 could effectively induce the inhibition of viral replication in MARC-145. Results showed that cells expressing the Nsp2 gene of the highly pathogenic PRRSV TJ and attenuated TJM remained stable. PRRSV replication was faster in these cells than in MARC-145 cells, especially during the early stage. This shows that Nsp2 plays a positive role in PRRSV proliferation. PMID:22959006

    This study examined the geologic data, mining history, and subsidence trends of the St. David region. Mine subsidence has occurred due to collapse of the abandoned mine workings. The known subsidence areas have been mapped and described. Results of the study include: (1) St. David has been undermined by both large shipping mines and smaller local mines; (2) sinkholes will continue to develop in this area in response to rock failure and roof collapse above the abandoned mine workings; (3) some primary factors that contribute to the sinkhole problems are the undermining and roof rock composition; (4) sinkholes will be smaller in the future; (5) ten of the 63 sinkholes occurred close enough to structures to cause damage, and only six sinkholes caused damage; (6) ways to minimize potential damage to future homes from sinkhole subsidence are manageable; (7) threats to residents lie in the collapse of heavy walls, brick chimneys, breaks in gas, water, or electrical lines; and (8) location of future subsidence is not predictable.

    Mycotoxins are secondary fungal metabolites that are capable of inducing a variety of toxic effects in animals and humans resulting from the consumption of the contaminated food. Understanding the mechanisms of the toxicities behind these mycotoxins is required to develop mechanism-based approach to counteract their toxic potential. Fumonisin B1 (FB1) is the most prevalent member of fumonisins that are a group of mycotoxins produced primarily by Fusarium verticillioides and Fusarium proliferatum. Kidney is one of the primary target organs for FB1 action. Using monkey kidney MARC-145 cells as an intro model, we found that FB1 induced caspase-independent programmed cell death accompanied with autophagy induction. Inhibition of autophagy by either chemical inhibitors or RNAi approach led to a significant reduction in cell death by FB1 exposure, indicating possible involvement of autophagy-mediated cell death in nephrotoxicity of FB1. Further mechanistic investigation revealed that activation of ERN1-MAPK8/9/10 axis played a critical role in autophagy induction and autophagy-mediated cell death by FB1 exposure. In addition, we demonstrated that disruption of sphingolipid metabolism was an apical event in FB1-induced ERN1-MAPK8/9/10-mediated autophagic cell death in MARC-145 cells. Lastly, we identified curcumin, a naturally occurring plant phenolic compound, as a possible anti-FB1 agent that can be used to protect kidney cells from FB1-induced cell death through inhibition of MAPK8/9/10 activation.

    David Crighton, a greatly admired figure in fluid mechanics, Head of the Department of Applied Mathematics and Theoretical Physics at Cambridge, and Master of Jesus College, Cambridge, died at the peak of his career. He had made important contributions to the theory of waves generated by unsteady flow. Crighton's work was always characterized by the application of rigorous mathematical approximations to fluid mechanical idealizations of practically relevant problems. At the time of his death, he was certainly the most influential British applied mathematical figure, and his former collaborators and students form a strong school that continues his special style of mathematical application. Rigorous analysis of well-posed aeroacoustical problems was transformed by David Crighton.

    Modern 3D scanning technologies allow to reconstruct 3D digital representations of Cultural Heritage artifacts in a semi-automatic way, characterized by very high accuracy and wealth of details. The availability of an accurate digital representation opens several possibilities of utilization to experts (restorers, archivists, museum curators), or to ordinary people (students, museum visitors). 3D scanned data are commonly used for the production of animations, interactive visualizations, or virtual reality applications. A much more exciting opportunity is to use these data in the restoration of Cultural Heritage artworks. The integration between 3D graphic and restoration represents an open research field where many new supporting tools are required; the David restoration project has given several starting points and guidelines to the definition and development of innovative solutions. Digital 3D models can be used in two different but not subsidiary modes: as an instrument for the execution of specific investigations and as a supporting media for the archival and integration of all the restoration-related information, gathered with the different studies and analysis performed on the artwork. In this paper we present some recent work done in the framework of the Michelangelo's David restoration project. A 3D model of the David was reconstructed by the Digital Michelangelo Project, using laser-based 3D scanning technology. We have developed some tools to make those data accessible and useful in the restoration. Preliminary results are reported here together with some directions for further research.

    The effects of fermented paste made from soybean, brown rice, or brown rice in combination with rice bran or red ginseng marc on the glucose metabolism and antioxidative defense system in high fat-fed mice were investigated. The mice were given experimental diets for eight weeks: Normal control, high fat, and high fat supplemented with soybean fermented paste, brown rice fermented paste, brown rice-rice bran fermented paste, or brown rice-red ginseng marc fermented paste. The high fat group showed markedly higher blood glucose level and erythrocyte lipid peroxidation than the normal control group. Diet supplementation of fermented paste inhibited the high fat-induced hyperglycemia and oxidative stress via regulation of the glucose-regulating and antioxidant enzymes activities. The soybean and brown rice-red ginseng marc fermented pastes were the most effective in improving the glucose metabolism and antioxidant defense status in mice under high fat diet condition. These findings illustrate that brown rice, in combination with red ginseng marc, may be useful in the development of fermented paste with strong hypoglycemic and antioxidative activities.

    2007-06-01

    We regret to announce the death of David Dew-Hughes, the second Honorary Editor of Superconductor Science and Technology, in Autumn 2006. He was born in Manchester, the eldest of three children, attended Manchester Grammar School and took his first degree in metallurgy at Birmingham, before undertaking a Doctorate of Engineering at Yale University. After initial work for IBM on semiconductors, he returned to England as a lecturer in metallurgy at Cambridge University. There he devoted his career to superconductivity long before it became fashionable, starting a group on the properties of what we now know as type II materials, with his students Jan Evetts, Archie Campbell and Anant Narlikar. Between them they paved the way to our understanding of the magnetic vortex properties of these materials, and thus to the development of modern practical materials for superconducting magnets. Eur.Ing. Professor David Dew-Hughes 1932-2006 In 1965 he became a founding Senior Lecturer in physics at Lancaster University, moving to Brookhaven National Laboratory in 1974. His final academic post was in engineering science at Oxford University where he also held a University College Tutorial Fellowship. As long ago as 1971 David wrote an authoritative review for Reports on Progress in Physics on 'The metallurgical enhancement of type II superconductors'. Following the discovery of high-Tc superconductivity, IOP Publishing launched Superconductor Science and Technology in 1988 and he was a founder member of its Editorial Board. When Jan Evetts retired as Honorary Editor in 1992, David was the natural choice as his successor. He served a five year term and remained on the Board as Deputy Editor until the end of 2000. To mark the 10th anniversary of high-temperature superconductivity in 1997, David edited a special issue of Superconductor Science and Technology in which past and present members of the Editorial Board contributed reviews of their specialities. He noted that at that time

This Journal of Physics: Condensed Matter special issue is dedicated to the memory of David C Langreth. David is a dearly missed friend and mentor who inspired many of us. He was an outstanding condensed matter theorist and a scholar who greatly influenced us through his many-particle-physics based insights into density functional theory (DFT), surface science and related areas. His seminal works range from conserving formulations of interacting nonequilibrium transport [1] and formal-scattering theory [2] to an explicit formulation [3] of the exact DFT exchange-correlation energy in the adiabatic connection formula (ACF), the latter also being derived independently by Gunnarsson and Lundqvist [4]. David's portfolio also includes an analysis [5] that helped catalyze and guide the development of DFT from the local-density approximation (LDA) to the formulations of generalized gradient approximations (GGAs). Another salient contribution of David's is in the area of vdW interactions in materials. He was a key architect of the vdW density functional (vdW-DF) method [6, 7]. This method was developed in a long-standing Rutgers-Chalmers collaboration between David's group and that of Bengt I Lundqvist, later extending to a wider group of researchers on both sides of the Atlantic. Plasmons are collective excitations that depend on electron-density variation. The plasmon response can be seen as defining the nature of the LDA [4] and their description can thus also be seen as contributing to the success of GGA. The vdW-DF method is a regular constraint-based density functional (for ground-state DFT) which is derived within the ACF framework and which emphasizes the electrodynamical nature of the coupling between

    The Père David's Vole, Eothenomys melanogaster belongs to subfamily Arvicolinae. It is widespread in south China, and ranges into northern Southeast Asia. In this study, the complete mitochondrial genome sequence of Eothenomys melanogaster was determined. The mitogenome is 16,331 base pairs in length. The nucleotide sequence data of 12 heavy-strand protein-coding genes of E. melanogaster and other 17 rodents were used for phylogenetic analyses. Tree constructed using Bayesian phylogenetic methods demonstrated that E. melanogaster as a sister to E. chinensis, was clustered in subfamily Arvicolinae. The monophyly of the genus Eothenomys was supported as well with Eothenomys sister to the genus Myodes. PMID:26024146

    What does it mean to be a mentor in science? Definitions of mentorship are freely spouted in publications and include concepts such as academic support, professional development, role modeling, interaction, impartment of knowledge, evaluation of work, demonstration of methodology, etc. Perhaps most of us would agree with the duties listed. But just what does it mean, for example, to offer academic support? How might one facilitate professional development for a mentee? While we may agree to the general obligations of a mentor the specifics of what these entail would prove more controversial. This article will illustrate how easy it is to pick out a bad mentor. There are certain elements of conduct that, if practiced, undoubtedly put you in the "bad mentor" category. However, it is very difficult to explain just what it means to be not only an adequate mentor but also a stellar one. It may be easy to list the roles and responsibilities of a mentor but just how should they be performed/carried out? David Triggle is the model of an extraordinary mentor. The conclusion of this paper will focus on some specific mentorship activities David Triggle carried out that illustrate some of the intangible aspects of excellence in mentorship. PMID:26206190

  16. Recovery of handwritten text from the diaries and papers of David Livingstone

    During his explorations of Africa, David Livingstone kept a diary and wrote letters about his experiences. Near the end of his travels, he ran out of paper and ink and began recording his thoughts on leftover newspaper with ink made from local seeds. These writings suffer from fading, from interference with the printed text and from bleed through of the handwriting on the other side of the paper, making them hard to read. New image processing techniques have been developed to deal with these papers to make Livingstone's handwriting available to the scholars to read. A scan of the David Livingstone's papers was made using a twelve-wavelength, multispectral imaging system. The wavelengths ranged from the ultraviolet to the near infrared. In these wavelengths, the three different types of writing behave differently, making them distinguishable from each other. So far, three methods have been used to recover Livingstone's handwriting. These include pseudocolor (to make the different writings distinguishable), spectral band ratios (to remove text that does not change), and principal components analysis (to separate the different writings). In initial trials, these techniques have been able to lift handwriting off printed text and have suppressed handwriting that has bled through from the other side of the paper.

  17. David Weston--Ocean science of invariant principles, total accuracy, and appropriate precision

    Roebuck, Ian

    2002-11-01

    David Weston's entire professional career was as a member of the Royal Navy Scientific Service, working in the field of ocean acoustics and its applications to maritime operations. The breadth of his interests has often been remarked upon, but because of the sensitive nature of his work at the time, it was indeed much more diverse than his published papers showed. This presentation, from the successors to the laboratories he illuminated for many years, is an attempt to fill in at least some of the gaps. The presentation also focuses on the underlying scientific philosophy of David's work, rooted in the British tradition of applicable mathematics and physics. A deep appreciation of the role of invariants and dimensional methods, and awareness of the sensitivity of any models to changes to the input assumptions, was at the heart of his approach. The needs of the Navy kept him rigorous in requiring accuracy, and clear about the distinction between it and precision. Examples of these principles are included, still as relevant today as they were when he insisted on applying them 30 years ago.

    Enterocytozoon bieneusi is a zoonotic pathogen of the phylum Microspora that infects humans as well as a variety of animal species worldwide. While molecular epidemiologic studies have characterized this parasite in various hosts, isolates from many susceptible hosts have not yet been examined. In this study, E. bieneusi was isolated from 47 Pere David's deer (Elaphurus davidianus) in Henan, China and characterized via PCR analysis of the internal transcribed spacer (ITS) gene. E. bieneusi was detected in 16 out of 47 (34.0%) fecal specimens examined. Sequence analysis of the ITS revealed six known genotypes: type IV (4), EbpC (4), EbpA (4), BEB6 (2), COS-I (1), and COS-II (1). Of these, type IV, EbpC, and EbpA are known to cause human microsporidiosis worldwide, whereas the remaining genotypes are generally specific to ruminants. The present study indicated that Pere David's deer are naturally infected with E. bieneusi, predominantly with zoonotic genotypes, and may pose a risk for human transmission. PMID:25982030

  1. Exploring grape marc as trove for new thermotolerant and inhibitor-tolerant Saccharomyces cerevisiae strains for second-generation bioethanol production

    PubMed Central

    2013-01-01

    Background Robust yeasts with high inhibitor, temperature, and osmotic tolerance remain a crucial requirement for the sustainable production of lignocellulosic bioethanol. These stress factors are known to severely hinder culture growth and fermentation performance. Results Grape marc was selected as an extreme environment to search for innately robust yeasts because of its limited nutrients, exposure to solar radiation, temperature fluctuations, weak acid and ethanol content. Forty newly isolated Saccharomyces cerevisiae strains gave high ethanol yields at 40°C when inoculated in minimal media at high sugar concentrations of up to 200 g/l glucose. In addition, the isolates displayed distinct inhibitor tolerance in defined broth supplemented with increasing levels of single inhibitors or with a cocktail containing several inhibitory compounds. Both the fermentation ability and inhibitor resistance of these strains were greater than those of established industrial and commercial S. cerevisiae yeasts used as control strains in this study. Liquor from steam-pretreated sugarcane bagasse was used as a key selective condition during the isolation of robust yeasts for industrial ethanol production, thus simulating the industrial environment. The isolate Fm17 produced the highest ethanol concentration (43.4 g/l) from the hydrolysate, despite relatively high concentrations of weak acids, furans, and phenolics. This strain also exhibited a significantly greater conversion rate of inhibitory furaldehydes compared with the reference strain S. cerevisiae 27P. To our knowledge, this is the first report describing a strain of S. cerevisiae able to produce an ethanol yield equal to 89% of theoretical maximum yield in the presence of high concentrations of inhibitors from sugarcane bagasse. Conclusions This study showed that yeasts with high tolerance to multiple stress factors can be obtained from unconventional ecological niches. Grape marc appeared to be an unexplored and

He does so for the same reason that Evelyn Waugh does: "the grim invasion of trader, administrator, missionary, and tourist" has changed all that (p. 174). Touring Hawaii in July of '09, Bittner was interested to discover some unusual bits of American heritage, but saddened to see how "civilization" and "Americanization" actually seem to have eroded the Hawaiian people's rights to life, liberty, and the pursuit of happiness. Bittner's dual religious heritage-Judaism by birth and upbringing and Catholicism by choice in mid-life-has given him the perspective to apply the lessons of Hawaiian history to his own personal issues, particularly forgiveness.

    2015-03-01

    The psychiatric aspects of David Hartley's writings have received less attention than the rest of his work. This Classic Text deals with Section VI of his Observations on Man …, namely, the 'Imperfections of the rational Faculty'. Hartley defines madness as an imperfection of reason that can be temporary or enduring. He makes use of his model of mental functioning to differentiate between eight clinical categories of madness, each representing a different pattern of vibrations of the nerves. Hartley developed this model based on Newton's theory of vibrations and, to explain the complexity of mental acts and entities, he combined it with his own version of the mechanism of Association of Ideas borrowed from John Locke. Much work needs to be done to identify the provenance of Hartley's nosology and nosography. PMID:25698690

    The mitochondrial amidoxime reducing component mARC is the fourth mammalian molybdenum enzyme. The protein is capable of reducing N-oxygenated structures, but requires cytochrome b5 and cytochrome b5 reductase for electron transfer to catalyze such reactions. It is well accepted that the enzyme is involved in N-reductive drug metabolism such as the activation of amidoxime prodrugs. However, the endogenous function of the protein is not fully understood. Among other functions, an involvement in lipogenesis is discussed. To study the potential involvement of the protein in energy metabolism, we tested whether the mARC protein and its partners are regulated due to fasting and high fat diet in mice. We used qRT-PCR for expression studies, Western Blot analysis to study protein levels and an N-reductive biotransformation assay to gain activity data. Indeed all proteins of the N-reductive system are regulated by fasting and its activity decreases. To study the potential impact of these changes on prodrug activation in vivo, another mice experiment was conducted. Model compound benzamidoxime was injected to mice that underwent fasting and the resulting metabolite of the N-reductive reaction, benzamidine, was determined. Albeit altered in vitro activity, no changes in the metabolite concentration in vivo were detectable and we can dispel concerns that fasting alters prodrug activation in animal models. With respect to high fat diet, changes in the mARC proteins occur that result in increased N-reductive activity. With this study we provide further evidence that the endogenous function of the mARC protein is linked with lipid metabolism. PMID:25144769

    Objective Even though minimally invasive cardiac surgery may reduce morbidity, this approach is not routinely performed for aortic root replacements. The purpose of this pilot study was to assess the safety and feasibility of valve sparing aortic root replacement via an upper mini-sternotomy up to the 3rd intercostal space. Methods Between April 2011 and March 2014, 26 patients (22 males, age 47.6±13 years) underwent elective minimally invasive aortic valve sparing root replacement (David procedure, group A). Twelve patients underwent additional leaflet repair. Concomitant procedures were: four proximal aortic arch replacements and one coronary artery bypass grafting (CABG) to the proximal right coronary artery (RCA). During the same time period, 14 patients (ten males, age 64.2±9.5 years) underwent elective David procedure via median full sternotomy (group B). Concomitant procedures included six proximal aortic arch replacements. Although the patient cohorts were small, the results of these two groups were compared. Results In group A, there were no intra-operative conversions to full sternotomy. The aortic cross-clamp and cardiopulmonary bypass (CPB) times were 115.6±30.3 and 175.8±41.9 min, respectively. One patient was re-opened (via same access) due to post-operative bleeding. The post-operative ventilation time and hospital stay were 0.5±0.3 and 10.4±6.8 days, respectively. There was no 30-day mortality. The patient questionnaire showed that the convalescence time was approximately two weeks. In group B: the cross-clamp and CPB times were 114.1±19.9 and 163.0±24.5 min, respectively. One patient was re-opened (7.1%) due to post-operative bleeding. The post-operative ventilation time and hospital stay were 0.6±0.7 and 14.2±16.7 days, respectively. There was no 30-day mortality. Conclusions Minimally invasive valve sparing aortic root replacement can be safely performed in selected patients. The results are comparable to those operated via a full

    2009-01-01

    The Point of View by Gregory Pauly, David Hillis, and David Cannatella misrepresents the motives and activities of the anuran subcommittee of the Scientific and Standard English Names Committee, contains a number of misleading statements, omits evidence and references to critical literature that have already rejected or superseded their positions, and cloaks the limitations of their nomenclatural approach in ambiguous language. Their Point of View is not about promoting transparency in the process of constructing the English Names list, assuring that its taxonomy is adequately reviewed, or promoting nomenclatural stability in any global sense. Rather, their Point of View focuses in large part on a single publication, The Amphibian Tree of Life, which is formally unrelated to the Standard English Names List, and promotes an approach to nomenclature mistakenly asserted by them to be compatible with both the International Code of Zoological Nomenclature and one of its competitors, the PhyloCode.

    2015-11-15

    David Triggle's scientific career began as a chemist, went through medicinal chemistry into pharmacology, and finally on to somewhat more philosophical interests in later years. It was a career marked by many contributions to all of those aspects of science. Chief amongst his many contributions, in addition to those in medicinal chemistry, was his work on the drugs known as calcium ion channel blockers or (calcium antagonists). In the calcium ion channel field he was a particularly instrumental figure in sorting out the mechanisms, actions and roles of the class of calcium channel blockers, known chemical and pharmacologically as the dihydropyridines (DHPs) in particular, as well as other calcium blockers of diverse structures. During the course of a long career, and extensive journeys into medicinal chemistry and pharmacology, he published voluminously in terms of papers, reviews, conference proceedings and books. Notably, many of his papers often had limited authorship where, as senior author it reflected his deep involvement in all aspects of the reported work. His work always helped clarify the field while his incisive reviews, together with his role in coordinating and running scientific meetings, were a great help in clarifying and organizing various fields of study. He has had a long and illustrious career, and is wellknown in the world of biomedical science; his contributions are appreciated, and well recognized everywhere. The following article attempts to chart a path through his work and contributions to medicinal chemistry, pharmacology, science, academia and students. PMID:26206197

    In this study, we report the complete mitochondrial genome sequence of David's myotis, Myotis davidii. The genome is found to be 17,531 bp in length and has a base composition of A (33.8%), G (13.2%), C (23.2%), and T (29.8%). Similar to other bats, it contains a typically conserved structure including 13 protein-coding genes, 22 transfer RNA genes, 2 ribosomal RNA genes, and 1 control region (D-loop). Most of the genes are encoded on H-strand, except for the ND6 subunit gene and 8 tRNA genes. All protein-coding genes start with an ATG codon except for ND2, ND3 and ND5, which initiate with ATT or ATA instead, and terminate with the typical stop codon (TAA/TAG) or a single T (T-) or an unexpected codon of AGA. The complete mitochondrial genome sequence provided here would be useful for further phylogenetic analysis and population genetic studies in M. davidii. PMID:25208182

    2016-05-01

    This is a confession building on a conversation with David Sackett in 2004 when I shared with him some personal adventures in evidence-based medicine (EBM), the movement that he had spearheaded. The narrative is expanded with what ensued in the subsequent 12 years. EBM has become far more recognized and adopted in many places, but not everywhere, for example, it never acquired much influence in the USA. As EBM became more influential, it was also hijacked to serve agendas different from what it originally aimed for. Influential randomized trials are largely done by and for the benefit of the industry. Meta-analyses and guidelines have become a factory, mostly also serving vested interests. National and federal research funds are funneled almost exclusively to research with little relevance to health outcomes. We have supported the growth of principal investigators who excel primarily as managers absorbing more money. Diagnosis and prognosis research and efforts to individualize treatment have fueled recurrent spurious promises. Risk factor epidemiology has excelled in salami-sliced data-dredged articles with gift authorship and has become adept to dictating policy from spurious evidence. Under market pressure, clinical medicine has been transformed to finance-based medicine. In many places, medicine and health care are wasting societal resources and becoming a threat to human well-being. Science denialism and quacks are also flourishing and leading more people astray in their life choices, including health. EBM still remains an unmet goal, worthy to be attained. PMID:26934549

    ABSTRACT A 47-year-old woman diagnosed with Marfan syndrome underwent valve-sparing aortic root replacement for aortic regurgitation and annulo-aortic ectasia. Her cardiac function was normal. Preoperative coronary angiography did not demonstrate any stenosis. The David reimplantation procedure with a 28-mm Valsalva graft was performed. Both coronary orifices were reconstructed in a button fashion with Teflon felt reinforcement. After aortic declamping, marked bleeding was noted from the left coronary button, requiring a second pump run. Graft interposition using the great saphenous vein was performed for left coronary artery reconstruction. The reconstructed right coronary button was also damaged due to the fragile tissue, and interposed by the vein graft in the same fashion. After the aorta was declamped, the global left ventricular wall motion was significantly impaired, and did not improve with time. Coronary insufficiency was considered. Beating-heart coronary artery bypass grafting with the in-situ bilateral internal thoracic arteries was performed. After revascularization, the left ventricular function was improved. In certain emergent situations compromised with coronary insufficiency, this procedure could be an option to revascularize the coronary arteries. PMID:26412900

    In early 1970s first personal desk-top computers started to be available in hospitals. Mr Price was one of the pioneers introducing his own software to identify Marmarou's model of CSF space during infusion studies to diagnose patients suffering from hydrocephalus. His closed-loop control system for infusion of mannitol to manage patients at risk of intracranial hypertension was designed in 1977. The system worked successfully for 10 years in Pinderfields Hospital in Wakefield, UK. In the middle 1980's he initiated international cooperation with Children's Health Centre in Poland in long-term computer-assisted monitoring and analysis of ICP. Software designed in a course of this cooperation paved the way for contemporary package of ICM+ (Intensive Care Monitor, University of Cambridge, UK). Our scientific portfolio from these years (1985-1995) contains hundreds of head injured patients with waveform ICP analysis, introduction of compensatory reserve index RAP, few highly cited papers. Now, we understand ICP much better thanks to David's personal passion and extremely friendly support. PMID:25721034

    2008-04-01

    The specific heat of hydrogen gas at low temperatures, first measured by Arnold Eucken in 1912, decreases sharply as the two rotational degrees of freedom freeze out. The ``old quantum theory'' could never explain this behavior satisfactorily, despite persistent efforts. Then in 1926, Heisenberg showed that in the new quantum mechanics, identical particles must have either symmetric or antisymmetric wave functions, and were the key to the spectrum of helium. Friedrich Hund first applied this concept to the rotational specific heat of hydrogen, with limited success. An experimental breakthrough came in 1926, when for the first time, spectral lines involving the ground state of molecular hydrogen were found in the far ultraviolet. Further measurements by the Japanese spectroscopist Takeo Hori led to a moment of inertia for molecular hydrogen more than double earlier estimates. Using this result, the American physicist David Dennison devised the modern theory in 1927, and in the process, found persuasive evidence for proton spin. Most of these actors were at Bohr's institute in Copenhagen in 1926--27; their interaction plays a central role in this story.

  13. Plasticity, stability, and yield: the origins of Anthony David Bradshaw's model of adaptive phenotypic plasticity.

    2015-04-01

    Plant ecologist Anthony David Bradshaw's account of the evolution of adaptive phenotypic plasticity remains central to contemporary research aimed at understanding how organisms persist in heterogeneous environments. Bradshaw suggested that changes in particular traits in response to specific environmental factors could be under direct genetic control, and that natural selection could therefore act directly to shape those responses: plasticity was not "noise" obscuring a genetic signal, but could be specific and refined just as any other adaptive phenotypic trait. In this paper, I document the contexts and development of Bradshaw's investigation of phenotypic plasticity in plants, including a series of unreported experiments in the late 1950s and early 1960s. Contrary to the mythology that later emerged around Bradshaw's ideas, Bradshaw was engaged in a serious and sustained empirical research program concerning plasticity in the 1950s and 1960s that went far beyond a single review paper. Moreover, that work was not isolated, but was surrounded by an already rich theoretical discourse and a substantial body of empirical research concerning the evolution of developmental plasticity and stability. Bradshaw recast the problem of how to understand (and control) plasticity and stability within an epistemic framework focused on genetic differences and natural selection. PMID:25641217

    Wang, Yang; Cerling, T. E.; Quade, J.; Bowman, J. R.; Smith, G. A.; Lindsay, E. H.

    Stable isotopes of paleosol carbonates from the St. David Formation in Arizona indicate a major change in δ18O and δ13C from ˜3.4 to 2.8 Ma ago, approximately the time of the onset of global cooling postulated from the deep-sea oxygen record. Another major shift in isotopic signature occurred at ˜2.4 to 1.8 Ma ago. δ13C values of paleosol carbonates also indicate that grasses were an important component of the local ecosystems at least since 3.4 Ma. δ13C values of fossil herbivorous mammal teeth from the St. David Formation also indicate that grasses had been available to support these C4 eaters (grazers) from 3.4 to 0.6 Ma, which is consistent with the paleosol carbonate results.

    Accuracy and precision of leaf positioning in multileaf collimators (MLCs) are significant factors for the accuracy of IMRT treatments. This study aimed to inves-tigate the accuracy and repeatability of the MLC leaf positioning via the DAVID invivo dosimetric system for dynamic and static MLC systems. The DAVID system was designed as multiwire transmission ionization chamber which is placed in accessory holder of linear accelerators. Each wire of DAVID system corresponds to a MLC leaf-pair to verify the leaf positioning accuracy during IMRT treatment and QA. In this study, verifications of IMRT plans of five head and neck (H&N) and five prostate patients treated in a Varian DHX linear accelerator with 80-leaf MLC were performed using DAVID system. Before DAVID-based dosimetry, Electronics Portal Imaging Device (EPID) and PTW 2D ARRAY dosimetry system were used for 2D verification of each plan. The measurements taken by DAVID system in the first day of the treatments were used as reference for the following measurements taken over the next four weeks. The deviations in leaf positioning were evaluated by "Total Deviation (TD)" parameter calculated by DAVID software. The delivered IMRT plans were originally prepared using dynamic MLC method. The same plans were subsequently calculated based on static MLC method with three different intensity levels of five (IL5), 10 (IL10) and 20 (IL20) in order to compare the performances of MLC leaf positioning repeatability for dynamic and static IMRT plans. The leaf positioning accuracy is also evaluated by analyzing DynaLog files based on error histograms and root mean square (RMS) errors of leaf pairs' positions. Moreover, a correlation analysis between simultaneously taken DAVID and EPID measurements and DynaLog file recordings was subsequently performed. In the analysis of DAVID outputs, the overall deviations of dynamic MLC-based IMRT calculated from the deviations of the four weeks were found as 0.55% ± 0.57% and 1.48% ± 0

In the wake of his passing, we are left not only with a feeling of great loss, but with a tremendous and impactful body of work contributed by a remarkable man. David's research spanned the spectrum from atomic structure to organ systems, with a quantitative rigor aimed at understanding the fundamental mechanisms underlying biological function. Along the way he developed new tools and approaches, enabling not only his own research but that of his contemporaries and those who will come after him. While we cannot hope to replicate the eloquence and style we are accustomed to in David's writing, we nonetheless undertake a review of David's chosen field of study with a focus on many of his contributions to the calcium channel field.

To seize them, companies must see how the current upheavals will affect the future distribution of profits--and then reinvent themselves to capitalize on the new sources of value. In this interview with HBR senior editor David Champion, Mark Levin, the founder and CEO of Millennium Pharmaceuticals, describes his vision of the future of the pharmaceutical industry in the wake of the genetics revolution and new technologies that have altered the economics of drug development. No company, he argues, will create serious long-term value by staying in just one or two stages of the value of chain. That's why Millennium, which started out doing basis research into genes and proteins and selling its findings to pharmaceutical giants, has moved downstream - toward the patients who actually use and pay for the drugs. He explains why the research end has become less lucrative than the more mechanical tasks of identifying, testing, and manufacturing molecules. Levin talks about the changes Millennium has undergone since its inception in 1993-from 30 workers to more than 1,000, and from one end of the value chain to the other. He discusses the company's cultural transformations as well as the partnerships and acquisitions that have helped millennium become involved in every stage of the chain-from gene to patient. Levin's vigorous approach to balancing long-term strategy with short-term tactics offers important lessons to any executive facing an industry upheaval. PMID:11408971

  5. Progressive deformation of an evaporite-bearing accretionary complex: SeaMARC I, SeaBeam and piston-core observations from the Mediterranean Ridge

    The Mediterranean Ridge is an arcuate ridge of deformed sediment caught up in the convergent plate margin between the African plate and the Aegean. An intensive campaign of SeaMARC I and SeaBeam surveys followed by piston coring has been conducted along the contact between undeformed turbidites of the Sirte Abyssal Plain and folded and faulted sediments of the Mediterranean Ridge. Along the outer edge of the Ridge, surficial sediments have been deformed into sinusoidal ridges and troughs (wavelengths 0.5 2 km, amplitude 20 150 m), which we interpret as folds. In plan view, the ridge and the trough fabric parallels the NW-SE trending regional contours, suggesting that the folds formed in response to compression orthogonal to the Mediterranean Ridge. The outermost ridge is shedding a debris apron out onto the abyssal plain, implying that uplift and deformation are ongoing. We show that the geometry of the outermost folds can be produced by elastic bending of a packet of 5 10 relatively strong layers, each 10 20 m thick, interbedded between weaker layers; we equate the strong layers with gypsum beds in the Messinian upper evaporites. Folding the seafloor from a flat layer into the observed ridge and trough topography would shorten the layer by less than 2%. Two percent shortening (equals two percent thickening) is insufficient to create the observed relief of the Mediterranean Ridge even if the entire sediment column down to basement were involved; we infer that additional shortening/thickening is accommodated by thrust faulting above a decollement at the top of the Messinian salt layer. At distances > 15 km from the deformation front and more than 500 m from the abyssal plain, sharp-edged, fine-grained side-scan lineations with very little vertical relief cut across the kilometer-scale ridge and trough topography. These fine-grained lineations fall in two groups trending N/S to NNE/SSW and ~ENE. We interpret these lineaments as traces of conjugate strike-slip faults

  6. Structural evolution of the East Pacific Rise axis from 13°10'N to 10°35'N: interpretations from SeaMARC I data

    In 1983 the SeaMARC I and the Sea Beam systems imaged the East Pacific Rise (EPR) and the Clipperton Transform Fault from 13°10'N to 9°50'N revealing both magmatic and tectonic segmentation along the rise axis. Tectonic segments are defined by an undulating axial zone of extension which widens and narrows at an average wavelength of 45 km. In addition, axial fissure-fault-density and -length curves reveal wavelengths of 30 and 56 km. The narrowest axial zones, < 0.5 km in width, correspond to regions of hydrothermal activity and are located atop regional morphologic highs quasi-harmonically spaced at 155 km. These highs define the major magma centers on the rise axis about which seamounts cluster. Superimposed on the intermediate-wavelength highs are smaller highs (from 10 to 50 km in length) which are truncated by overlapping spreading centers (OSC's) at their distal edges. The rise axis widens near OSC's while it narrows and disappears near the Clipperton Transform Fault suggesting that transforms and OSC's have different origins. Imagery on and adjacent to a few OSC's reveals that in some cases OSC's migrate along the axis forming relict off-axial structural traces at oblique angles (285°-330°) to the axis. Off-axial fault density and length curves have wavelengths similar to the axial curves. However, fault densities to the west of the axis are somewhat antisymmetric to fissure-fault densities on the axis. In contrast, faults to the east of the axis nearly mimic fissure-fault density and length curves on the axis suggesting that the fracture pattern is controlled by the state of deviatoric stress in the adjacent Cocos Plate to the east. The data suggest that large deep-seated magma diapirs may dominate the magmatic segmentation of the EPR generating dynamically supported 155 km wavelength highs. Smaller, shallower magma cupulas may rise as fingers to the seafloor above the large diapirs. Where the magma erupts may be a factor of the thin skin tectonic

  8. "implicate Order" and the Good Life: Applying David Bohm's Ontology in Human World

    NASA Astrophysics Data System (ADS)

    Ravn, Ib.

    In an attempt to formulate a coherent view of quantum reality, the theoretical physicist David Bohm has proposed a new concept of order to supplement the mechanistic Cartesian order of traditional physics. The "implicate" order is a subtler and deeper order that emphasizes "unbroken wholeness in flowing movement," in contrast to the coarser and more superficial, "explicate" Cartesian order of distinct phenomena. This dissertation attempts to develop a meaning for the idea of implicate order in the world of human experience. First is offered an account of some evolutionary episodes in terms of implicate and explicate order which draws on compatible work in cosmology, embryogenesis, visual perception, brain memory, decision making and phenomenology. Two important characteristics of the implicate order are then identified: in an implicate order, the whole is enfolded (or represented) in its parts; and all parts render different perspectives of the whole. Using arguments from decision making, the study of "flow" in human consciousness, and a model of skill acquisition, it is suggested that these characteristics manifest themselves in the human world as the "unity experience" and the "diversity experience," respectively. The former is the experience that a given part of one's life reveals a larger wholeness or unity; the subject-object distinction is transcended and one becomes absorbed in the flow of whatever activity is pursued. The latter is a deep appreciation of the diversity of ways in which people may seek the unity experience. These experiences are proposed as general values: social and psychological conditions ought to be such that these experiences are enhanced in all people. A two-by-two matrix of the two experiences demonstrates the danger of pursuing one to the exclusion of the other. The experience of unity without diversity turns into absolutism, the insistence that one's chosen activities or beliefs are the only right ones. The experience of diversity

    The US Air Mobility Command (AMC) has tasked Pacific Northwest Laboratory (PNL) with supporting the US Department of Energy (DOE) Federal Energy Management Program`s (FEMP) mission to identify, evaluate, and assist in acquiring all cost-effective energy resource opportunities (EROs) at the David Grant Medical Center (DGMC). This report describes the methodology used to identify and evaluate the EROs at DGMC, provides a life-cycle cost (LCC) analysis for each ERO, and prioritizes any life-cycle cost-effective EROs based on their net present value (NPV), value index (VI), and savings to investment ratio (SIR or ROI). Analysis results are presented for 17 EROs that involve energy use in the areas of lighting, fan and pump motors, boiler operation, infiltration, electric load peak reduction and cogeneration, electric rate structures, and natural gas supply. Typical current energy consumption is approximately 22,900 MWh of electricity (78,300 MBtu), 87,600 kcf of natural gas (90,300 MBtu), and 8,300 gal of fuel oil (1,200 MBtu). A summary of the savings potential by energy-use category of all independent cost-effective EROs is shown in a table. This table includes the first cost, yearly energy consumption savings, and NPV for each energy-use category. The net dollar savings and NPV values as derived by the life-cycle cost analysis are based on the 1992 federal discount rate of 4.6%. The implementation of all EROs could result in a yearly electricity savings of more than 6,000 MWh or 26% of current yearly electricity consumption. More than 15 MW of billable load (total billed by the utility for a 12-month period) or more than 34% of current billed demand could also be saved. Corresponding natural gas savings would be 1,050 kcf (just over 1% of current consumption). Total yearly net energy cost savings for all options would be greater than $343,340. This value does not include any operations and maintenance (O&M) savings.

    Permanent in vivo verification of IMRT photon beam profiles by a radiation detector with spatial resolution, positioned on the radiation entrance side of the patient, has not been clinically available so far. In this work we present the DAVID system, which is able to perform this quality assurance measurement while the patient is treated. The DAVID system is a flat, multi-wire transmission-type ionization chamber, placed in the accessory holder of the linear accelerator and constructed from translucent materials in order not to interfere with the light field. Each detection wire of the chamber is positioned exactly in the projection line of a MLC leaf pair, and the signal of each wire is proportional to the line integral of the ionization density along this wire. Thereby, each measurement channel essentially presents the line integral of the ionization density over the opening width of the associated leaf pair. The sum of all wire signals is a measure of the dose-area product of the transmitted photon beam and of the total radiant energy administered to the patient. After the dosimetric verification of an IMRT plan, the values measured by the DAVID system are stored as reference values. During daily treatment the signals are re-measured and compared to the reference values. A warning is output if there is a deviation beyond a threshold. The error detection capability is a leaf position error of less than 1 mm for an isocentric 1 cm x 1 cm field, and of 1 mm for an isocentric 20 cm x 20 cm field. PMID:16481690

    The 48-acre David Witherspoon, Inc. (DWI) 1630 Site operated as an unregulated industrial landfill and scrap yard. The Tennessee Division of Superfund (TDSF) closed the landfill in 1974. During the period of operation, the site received solid and liquid wastes from salvage and industrial operations. The site consists of five separate tracts of land including a small portion located across the Norfolk Southern Railroad track. The landfill occupies approximately 5 acres of the site, and roughly 20 acres of the 48 acres contains surface and buried debris associated with the DWI dismantling business operation. Beginning in 1968, the state of Tennessee licensed DWI to receive scrap metal at the DWI 1630 Site, contaminated with natural uranium and enriched uranium (235U) not exceeding 0.1 percent by weight (TDSF 1990). The U.S. Department of Energy (DOE) has agreed to undertake remedial actions at the DWI 1630 Site as specified under a Consent Order with the Tennessee Department of Environment and Conservation (TDEC) (Consent Order No. 90-3443, April 4, 1991), and as further delineated by a Memorandum of Understanding (MOU) between DOE and the State of Tennessee (MOU Regarding Implementation of Consent Orders, October 6, 1994). The soil and debris removal at the DWI 1630 Site is being performed by Bechtel Jacobs Company LLC (BJC) on behalf of the DOE. Remediation consists of removing contaminated soil and debris from the DWI 1630 site except for the landfill area and repairing the landfill cap. The DWI 1630 remediation waste that is being disposed at the Environmental Management Waste Management Facility (EMWMF) as defined as waste lot (WL) 146.1 and consists primarily of soils and soil like material, incidental debris and secondary waste generated from the excavation of debris and soil from the DWI 1630 site. The WL 146.1 includes soil, soil like material (e.g., shredded or chipped vegetation, ash), discrete debris items (e.g., equipment, drums, large scrap metal

    This article applies the moral sentimentalism founded by David Hume to the moral status of the embryo. It will attempt to explain the paradoxical fact that in Germany abortion is common and socially accepted while preimplantation genetic diagnosis is banned with the aid of an approach based on moral sentimentalism. David Hume established the thesis that the human being is guided by the emotions and not by reason when making moral decisions. Scientific innovations often create a feeling of anxiety. Consequently, the initial moral judgment about it is negative. Due to this habit, the innovation is often accepted after a phase of indifference. This phenomenon has been observed in the case of heart transplantation, as well as for IVF. Consequently, the apparent contradiction in the varying degrees of the embryo's worthiness of protection in the womb and in the Petri dish is due to the simple fact that these are different stages of habituation. Therefore, the ethics of Hume cannot stipulate the embryo's moral status for once and for all; however, they can paradoxically raise the ongoing current debate to a more rational level through the insight that the underlying moral concepts are not based on reason alone.

    David Triggle's career as an educator, researcher, essayist and ethicist in many ways has paralleled the post WWII emergence of the "biomedical research ecosystem" that originated in the concept of the "Endless Frontier". In the ensuing 70 years biomedical research has irreparably changed the nature of society with vaccines, the birth control pill and new generations of drugs and biologics to treat infections, sexually transmitted diseases, psychiatric disorders and cardiovascular diseases. These have led to a shift in the population demographic to the elderly and the chronically sick leading to major issues in the provision of effective and affordable healthcare for much of the world's population. In the present article, in addition to providing a brief biography and an appreciation of David Triggle's contributions to science, the authors expand on three topics in which he has had a major interest: improving the quality, reproducibility and relevance of basic biomedical research; declining career opportunities for graduates in an era of decreased funding-the end of the "Endless Frontier"; and the dynamic between the provision for universal healthcare and the dysfunctional, wasteful and politicized systems of the current medical-industrial complex in delivering healthcare.

    In his writings, David Orr claims that the US is in an "ecological crisis" and that this stems from a crisis of education. He outlines a theory of ecological literacy, a mode by which we better learn the ecology of the Earth and live in a sustainable manner. While emphasizing a shock doctrine, the diagnosis of "crisis" may be correct, but it is short-lived for children and adults of the world. In this philosophical analysis of Orr's theory, it is argued that we move beyond the perspective of crisis. By extending Orr's ecological literacy with biophilia and ecojustice and by recognizing the importance of experience-in-learning, science education is envisioned to incorporate values and morals within a longer term ideology of educational reform.

    2004-01-01

    In his paper "The Catholic Church, the American Military, and Homosexual Reorientation Therapy," David W. Lutz ultimately concludes that it is "appropriate, and highly ethical" for the American military to offer reorientation therapy to help homosexuals overcome "the vice of sodomy." The major thrust of his paper, however, is to call for abandonment of the "Don't Ask/Don't Tell" policy currently in place in the military. Lutz's paper covers much ground, and this review begins by examining whether such a wide view is necessary for the ultimate conclusions. It goes on to ask whether Lutz has omitted to mention important considerations bearing on this issue, and whether Lutz's call for the introduction of reorientation therapy is a serious call or a symbolic response to homosexual activities. Lutz fails to address essential issues such as the actual experiences of other nations having homosexuals in the military, and issues regarding what constitutes "reorientation therapy," the latter leading to questions about how such a therapy would actually be implemented.

    PubMed

    Robertson, Frances

    2013-09-01

    This paper examines codes of representation in nineteenth century engineering in Britain in relation to broader visual culture. While engineering was promoted as a rational public enterprise through techniques of spectacular display, engineers who aimed to be taken seriously in the intellectual hierarchies of science had to negotiate suitable techniques for making and using images. These difficulties can be examined in the visual practices that mark the career of engineer David Kirkaldy. Beginning as a bravura naval draughtsman, Kirkaldy later negotiated his status as a serious experimenter in material testing science, changing his style of representation that at first sight seems to be in line with the 'objective' strategy in science of getting nature to represent herself. And although Kirkaldy maintained a range of visual styles to communicate with different audiences, making rhetorical use of several technologies of inscription, from hand drawing to photography, nevertheless, his work does in fact demonstrate new uses of the concept of objectivity in representation when up against the practices of engineering. While these might seem merely pragmatic in comparison to the ethical weight given to the discourse of objective representation in science, in the messy world of collapsing bridges and law suits, virtuous engineers had to develop various forms of visual knowledge as practical science. This was not 'applied science' but a differentiated form of enquiry whose complexities hold as much interest as the better known visual cultures of late nineteenth century science or art.

    Three cDNA clones from Satsuma mandarin (Citrus unshiu Marc.) were isolated and expressed in Escherichia coli. CuSTS3-1 and CuSTS3-2 encode linalool synthases and CuSTS4 encodes a nerolidol/linalool synthase. Transcripts of CuSTS3-1, CuSTS3-2 and CuSTS4 were abundant in young fruit at 60 days after flowering (DAF), flowers and leaves, respectively. Treatments with Xanthomonas citri subsp. citri (XCC), the causal agent of citrus canker and Penicillium italicum (PI), the cause of post-harvest fruit decay, and wounding up-regulated CuSTS3-1 in fruit and mainly CuSTS4 in leaves. Linalool, citral, geraniol and citronellol showed strong antibacterial and antifungal activities against XCC and PI in vitro, while most other mono-and sesquiterpenes, including limonene and gamma-terpinene, did not. Linalool, used at levels similar to those present in resistant Ponkan mandarin (Citrus reticulata Blanco) leaves, was able to inhibit growth of XCC in vitro. Compared to other five citrus types, linalool accumulated at extraordinarily high levels in Ponkan mandarin leaves and was released at high amounts from their leaves, while it was hardly detectable in the most susceptible species, indicating that linalool biosynthesis and accumulation might be involved in plant defense against bacterial and fungal pathogens and be associated with field resistance to citrus canker.

He exemplified an inter-disciplinary scientist who was able to cross scientific boundaries effortlessly in order to provide amazing understanding on how calcium channels work. This article provides a glimpse of some of the research the authors have the privilege to collaborate with David and it attempts to provide the thinking behind some of the research done. In a wider context, we highlight that calcium channel function could be exquisitely modulated by interaction with a tethered calmodulin. Post-transcriptional modifications such as alternative splicing and RNA editing further influence the Ca2+-CaM mediated processes such as calcium dependent inhibition and/or facilitation. Besides modifications of electrophysiological and pharmacological properties, protein interactions with the channels could also be influenced in a splice-variant dependent manner. PMID:26054929

This article provides a glimpse of some of the research the authors have the privilege to collaborate with David and it attempts to provide the thinking behind some of the research done. In a wider context, we highlight that calcium channel function could be exquisitely modulated by interaction with a tethered calmodulin. Post-transcriptional modifications such as alternative splicing and RNA editing further influence the Ca(2+)-CaM mediated processes such as calcium dependent inhibition and/or facilitation. Besides modifications of electrophysiological and pharmacological properties, protein interactions with the channels could also be influenced in a splice-variant dependent manner. PMID:26054929

    David Reznick is one of the world's leading evolutionary biologists. His book on Charles Darwin's Origin of Species is given here in a précis, in order to show the underlying approach that he takes towards a work that is a classic in his field. It is shown that Reznick's interests are less in Darwin for his own sake and more in the importance of Darwin's ideas for science today.

    How to assess the potential habitat integrating landscape dynamics and population research, and how to reintroduce animals to potential habitats in environments highly human disturbed are still questions to be answered in conservation biology. According to behavioral research on Elaphurus davidians, we have developed a suitability index and a risk index to evaluate the potential habitats for the deer. With these indices, we conducted two transect assessments to evaluate the gradient change of the target region. Then, taking rivers as border lines, we tabulated the forest areas, high grassland area and total area and then compared the forest and high grassland area in each subregion. Furthermore, we computed the land use transfer matrix for the whole Yancheng coast during 1987-2000. We also computed human modified index (HMI) in six subregions. Lastly with a geographical information system support we obtained the spatial distribution of the indices and evaluation of the whole potential habitats from a neighborhood analysis. The transect assessment showed that the suitability of the coastal area was higher than that of the inland area for the deer, while the southern area was higher than the northern. Landscape metrics and HMI analysis showed that different landscape patterns and different anthropogenic disturbance existed within the region, and the increasing human disturbance was the key factor causing the pattern dynamics. The evaluation of potential habitats showed that there was an estimated carrying capacity of no more than 10,000 for David's deer reintroduction into the natural area. Also the reintroduction strategy was discussed. This integrated approach linked the population research and the landscape metrics, and the dataset with different scale; thus, it is an approach likely to be useful for the protection of other large animal in a landscape highly disturbed by humans.

    In the 1970s, David Rosenhan and seven other persons were hospitalized in twelve different psychiatric hospitals, pretending having heard voices uttering such words as void, hollow, thud. They were immediately hospitalized with a diagnosis of schizophrenia and, for one of them, of bipolar condition. Right after entering hospital, they reversed to normal behavior. None of them had a psychiatric history. Nevertheless, they were released after a time lapse of 7 to 52 days with a mean of 19 days. Release diagnosis was the same as the admission with the adjunct "in remission". D. Rosenhan points out the contextual and incertain aspect of the diagnosis and underlines the fact that it is apparently impossible to consider as being normal a person who has been admitted to a psychiatric hospital. Psychiatric labels stick to the skin. D. Rosenhan describes the pervasive boredom in a psychiatric hospital and the general set which leads to de-personalization. C. Chiland gives some precisions on what lead D. Rosenhan to undertake such an "experiment". She analyzes the reactions of the American psychiatric community which felt attacked in it's knowledge to the point of entirely rejecting the message. Indeed the criticism concerned the contextual aspect of diagnosis in the framework of the Gestaltpsychology and called to a necessary awareness of what is experienced by a hospitalized patient. Instead of seeking solutions to ward off the negative effects of the psychiatric hospital, effects that are inherent to any total institution, the community has rejected Rosenhan's experiment as being based on faking. Should a child psychiatrist feel securely innocent? The danger of labelling does exist for the children and their parents. Although a one-way choice in the dynamic contradiction between segregation and integration is not possible, one nevertheless has to remain vigilant regarding the institutions, even in day-care ones, so as to avoid imprisoning the child in rejection or

    Objective Valve sparing root replacement (VSRR) is an attractive option for the management of aortic root aneurysms with a normal native aortic valve. Therefore, we reviewed our experience with a modification of the David V VSRR and compared it with stented pericardial bioprosthetic valve conduit (BVC) root replacement in an age-matched cohort of older patients. Methods A total of 48 VSRRs were performed at our institution, excluding those on bicuspid aortic valves. We compared these cases with 15 aortic root replacements performed using a BVC during the same period. Subgroup analysis was performed comparing 16 VSRR cases and 15 age-matched BVC cases. Results The greatest disparity between the VSRR and BVC groups was age (53 vs 69 years, respectively; P < .0005). The matched patients were similar in terms of baseline demographics and differed only in concomitant coronary artery bypass grafting (2 VSRR vs 7 BVC patients; P = .036). None of the VSRR and 3 of the BVC procedures were performed for associated dissection (P = .101). Postoperative aortic insufficiency grade was significantly different between the 2 groups (P = .004). The cardiopulmonary bypass, crossclamp, and circulatory arrest times were not different between the VSRR and BVC groups (174 vs 187 minutes, P = .205; 128 vs 133 minutes, P = .376; and 10 vs 13 minutes, respectively; P = .175). No differences were found between the 2 groups with respect to postoperative complications. One postoperative death occurred in the BVC group and none in the VSRR group. The postoperative length of stay and aortic valve gradients were less in the VSRR group (6 vs 8 days, P = .038; 6 vs 11.4 mm Hg, P = .001). The intensive care unit length of stay was significantly less in the VSRR group (54 vs 110 hours, P = .001). Conclusions VSRR is an effective alternative to the BVC for aortic root aneurysm.

  19. David Liberman's legacy.

    Arbiser, Samuel

    2014-08-01

    This article presents, in the author's own vision, his attempt to consider (and update) the work of an original thinker of contemporary psychoanalysis (in the present). Following a short overview of his biographical data and distinctive traits as maestro and man, it then tries to capture the implications and panoramic vision of Liberman's work, the prevailing questions and problems of psychoanalysis to which it responds. In the author's opinion this involves a serious attempt to systematize clinical psychoanalysis on the basis of singularity and of tolerance to human diversity, with the greatest precision and scientific rigour admitted by the psychoanalytic discipline - avoiding cliché on the one hand and what we might call the mystification of the Oracle on the other. The successive stages of Liberman's production are indicated in terms of the auxiliary disciplines (communication theory, semiotics and linguistics) which he used for his ever more precise systematization of clinical psychoanalysis finally leading to his proposals on 'style' and his vision of the psychopathology of over-adaptation and psychosomatic instances. Other concepts which this paper highlights are: Liberman's conception of analytic dialogue as framed by human interaction; his theorization which stems from this particular empirical base making use of 'operational definitions' and 'intermediary formulations'; his operational definition of transference; and the inclusion of setting inside the 'analytic situation'.

  20. Supplementation of a grape seed and grape marc meal extract decreases activities of the oxidative stress-responsive transcription factors NF-κB and Nrf2 in the duodenal mucosa of pigs

    PubMed Central

    2013-01-01

    Background In pigs, enteric infections and the development of gut disorders such as diarrhoea are commonly observed, particularly after weaning. The present study investigated the hypothesis that feeding a grape seed and grape marc extract (GSGME) as a dietary supplement has the potential to suppress the inflammatory process in the small intestine of pigs by modulating the activities of NF-κB and Nrf2 due to its high content of flavonoids. Methods Twenty-four crossbred, 6 weeks old pigs were randomly assigned to 2 groups of 12 animals each and fed nutritionally adequate diets without or with 1% GSGME for 4 weeks. Results Pigs administered GSGME had a lower transactivation of NF-κB and Nrf2 and a lower expression of various target genes of these transcription factors in the duodenal mucosa than control pigs (P < 0.05). Concentrations of α-tocopherol and thiobarbituric acid reactive substances (TBARS) in liver and plasma and total antioxidant capacity of plasma and relative mRNA abundances of NF-κB and Nrf2 target genes in the liver did not differ between the two groups. However, the ratio of villus height:crypt depth and the gain:feed ratio was higher in the pigs fed GSGME than in control pigs (P < 0.05). Conclusions This study shows that dietary supplementation of a polyphenol rich GSGME suppresses the activity of NF-κB in the duodenal mucosa of pigs and thus might provide a useful dietary strategy to inhibit inflammation in the gut frequently occurring in pigs. Feeding GSGME did not influence vitamin E status and the antioxidant system of the pigs but improved the gain:feed ratio. In overall, the study suggests that polyphenol-rich plant extracts such GSGME could be useful feed supplements in pig nutrition, in order to maintain animal health and improve performance.

    During the periparturient phase, cows are typically in an inflammation-like condition, and it has been suggested that inflammation associated with the development of stress of the endoplasmic reticulum (ER) in the liver contributes to the development of fatty liver syndrome and ketosis. In the present study, we investigated the hypothesis that feeding grape seed and grape marc meal extract (GSGME) as a plant extract rich in flavonoids attenuates inflammation and ER stress in the liver of dairy cows. Two groups of cows received either a total mixed ration as a control diet or the same total mixed ration supplemented with 1% of GSGME over the period from wk 3 prepartum to wk 9 postpartum. Dry matter intake during wk 3 to 9 postpartum was not different between the 2 groups. However, the cows fed the diet supplemented with GSGME had an increased milk yield and an increased daily milk protein yield. Cows supplemented with GSGME moreover had a significantly reduced mRNA abundancy of fibroblast growth factor (FGF) 21, a stress hormone induced by various stress conditions, in the liver in wk 1 and 3 postpartum. In contrast, mRNA abundances of a total of 3 genes involved in inflammation and 14 genes involved in ER stress response, as well as concentrations of triacylglycerols and cholesterol, in liver samples of wk 1 and 3 postpartum did not differ between the 2 groups. Overall, this study shows that supplementation of GSGME did not influence inflammation or ER stress in the liver but increased milk yield, an effect that could be due to effects on ruminal metabolism.

    Recent scholarship has frequently emphasized modern states' use of social science to impose universalized conceptions of rationality and order upon diverse, highly localized settings. The New Deal era experiences of William M. Leiserson and David J. Saposs, however, provide an analytical alternative. As students of the pioneering labor economist John R. Commons, Leiserson and Saposs sought to create mechanisms for state oversight of industrial labor relations that recognized local practices and arrangements. Although their approach failed to take hold within the National Labor Relations Board, localized institutional and political contingencies, and not a hegemonic modernism, account best for their frustrated aspirations in the late 1930s.

    The Père David's deer is a highly inbred, but recovered, species, making it interesting to consider their adaptive molecular evolution from an immunological perspective. Prior to this study, genomic sequencing was the only method for isolating all functional MHC genes within a certain species. Here, we report a novel protocol for isolating MHC class II loci from a species, and its use to investigate the adaptive evolution of this endangered deer at the level of multi-locus haplotypes. This protocol was designated “HURRAH” based on its various steps and used to estimate the total number of MHC class II loci. We confirmed the validity of this novel protocol in the giant panda and then used it to examine the Père David's deer. Our results revealed that the Père David's deer possesses nine MHC class II loci and therefore has more functional MHC class II loci than the eight genome-sequenced mammals for which full MHC data are currently available. This could potentially account at least in part for the strong survival ability of this species in the face of severe bottlenecking. The results from the HURRAH protocol also revealed that: (1) All of the identified MHC class II loci were monomorphic at their antigen-binding regions, although DRA was dimorphic at its cytoplasmic tail; and (2) these genes constituted two asymmetric functional MHC class II multi-locus haplotypes: DRA1*01 ∼ DRB1 ∼ DRB3 ∼ DQA1 ∼ DQB2 (H1) and DRA1*02 ∼ DRB2 ∼ DRB4 ∼ DQA2 ∼ DQB1 (H2). The latter finding indicates that the current members of the deer species have lost the powerful ancestral MHC class II haplotypes of nine or more loci, and have instead fixed two relatively weak haplotypes containing five genes. As a result, the Père David's deer are currently at risk for increased susceptibility to infectious pathogens. PMID:21267075

    Evidence-based medicine (EBM) has increasingly influenced decision making in health policy and patient care. Appropriate use of EBM in decision making requires a clear understanding of the distinct "anatomical" components of all decisions: (1) scientific evidence and (2) judgments applied to that evidence by individuals or organizations. In this interview, Sean Tunis discusses these principles with David Eddy. Tunis has provided leadership at the national level in applying EBM principles to health policy decision making at the Office of Technology Assessment, the Centers for Medicare and Medicaid Services, and now the Center for Medical Technology Policy. Eddy is cofounder and medical director of Archimedes; he is widely recognized as a seminal contributor to evidence-based medicine, helping shape the initial ideas and applying them to guidelines, coverage policies, and performance measures.

    This article examines the career of pioneer British psychoanalyst David Eder (1865–1936). Credited by Freud as the first practising psychoanalyst in England, active in early British socialism and then a significant figure in Zionism in post-war Palestine, and in between an adventurer in South America, a pioneer in the field of school medicine, and a writer on shell-shock, Eder is a strangely neglected figure in existing historiography. The connections between his interest in medicine, psychoanalysis, socialism and Zionism are also explored. In doing so, this article contributes to our developing understanding of the psychoanalytic culture of early twentieth-century Britain, pointing to its shifting relationship to broader ideology and the practical social and political challenges of the period. The article also reflects on the challenges for both Eder’s contemporaries and his biographers in making sense of such a life. PMID:23752865

    In 1982 Dwight David Eisenhower Army Medical Center (DDEAMC) was providing radiation therapy support to authorized beneficiaries by referral to a local civilian proprietary firm. This was financed by supplemental care funds for active duty personnel and through CHAMPUS for other authorized beneficiaries. The establishment of an in-house radiation therapy center at DDEAMC was being considered when Congress directed the Department of Defense to implement a program to test the sharing of specialized services. This study devises a methodology for the analysis of costs associated with purchasing radiation-therapy services, and compares them with the costs for providing the cancer treatments in-house. The utilization of a decision matrix showed that the establishment of an in-house capability at DDEAMC which provides radiation therapy services for the surrounding region (26 military hospitals and clinics) is the alternative of choice.

    Walker, Theodore, Jr.

    2012-06-01

    Traditionally, astronomy met theology and political ethics in almanacs. As presented in early New England almanacs of the farmer's type, astronomy was deity-affirming and liberty-oriented. The old English label for astronomy that affirms theology was "Astro-theology" (William Derham, 1715). The New England rendering of astro-theology was so strongly oriented towards liberty that it can now be labeled astro-liberation theology. This 21st century label is appropriate because 18th century New England printers and astronomers used astronomy to demonstrate the glory of the Creator (astro-theology) and to encourage liberation from colonialism and slavery (astro-liberation theology). A philosophy of astronomy as "useful knowledge' expressed by David Rittenhouse in 1775 - and implicit in a Benjamin Banneker almanac for 1792 - included liberty-oriented visions of planet Earth as seen from outer space, and liberty-oriented visions of intelligent life on other planets orbiting other stars.

    NASA Astrophysics Data System (ADS)

    Maciel, Duan

    This dissertation addresses the common elements between ancient Celtic mystical doctrines and philosophy and David Bohm's unique theories in quantum physics through a Jungian lens, using research based in dialogical hermeneutics. The premise of this dissertation is that psi, or the probability wave function of quantum physics, and its world of potentia are the same entities as Jung's objective psyche (or collective unconscious) and its domain, the unus mundus. In addition, the study explores the remarkable similarity between the ancient Celts' Otherworld, quantum physics' world of potentia, and Jung's unus mundus. These similarities argue for an in-depth Jungian analysis of this important but largely neglected mythology. The study explores the supposition, based partially on physicist David Bohm's theories of the implicate and explicate orders, that the above world of potentia intertwines with our three-dimensional world in a reciprocal creativity, designed to enhance both worlds. The study further advocates a greater emphasis on the creative arts therapies in the therapeutic situation, based on the above reciprocity. It is argued that this emphasis on creativity in the temenos may activate a profound "quantum leap" of insight in the analysand, most likely due to the reciprocity in which the objective psyche responds uniquely to the particular and individual creativity offered in order to heal the personal psyche. As we creatively access the objective psyche, that entity responds in kind, giving us new understanding and allowing us to change our attitudes and to further individuation, which in turn enhances the objective psyche. In addition, a psyche of reality is postulated in which Jung's concept of the objective psyche is expanded from the collective unconscious of humankind to a collective unconscious of All That Is, reflecting the findings in quantum physics that our universe is self-aware, organic, and holistic rather than mechanical and fragmented.

    The Belfast-born David Walker was the 19-year-old surgeon and naturalist on the epic Fox Arctic Expedition (1857-59) that established the fate of Sir John Franklin's unsuccessful (1845) search for the North-West Passage. On return the crew were fêted as heroes and decorated, and shared in a £5000 government bounty: Walker was also received by the Queen and (in Ireland) by the Lord Lieutenant, was honoured by the principal British and Irish natural history societies and his portrait was exhibited in the National Portrait Gallery, London. This paper describes his adventurous life, including the Fox Expedition, which from 1862 was spent abroad and included time in the Cariboo gold fields, service in the United States Army, practice in a notorious Californian frontier town and, in later life, the comparative quiet of general and occupational medical practice in Portland, Oregon. Once a household name, his death went unrecorded in the British and Irish medical and lay press. PMID:23143316

    In writing this review, I draw on the experience of David Greenwood (Cult Stud Sci Educ 10:5-16, 2015) whose ethnographic study sheds light on his growth as a faculty member who has taught in various settings that are quite different from the culture that he grew up with. I extend his thoughts on ecological mindfulness to encompass a culturally aware method of teaching based on place sensitized more to the needs of science teacher preparation programs. The methods used in writing the review included literature searches for articles that incorporate ecological mindfulness and culturally responsive teaching in science teacher preparation programs and reflected ideas voiced in Greenwood's article. Although he seems that he is primarily addressing other faculty members, his experiences can be used as lifelong lessons for preservice teachers entering a primarily homogeneous workforce expected to teach an increasingly diverse student population. His humor, use of Haiku, poetry and mindfulness as a way of becoming one with a culture that he is not accustomed has many lessons that prove useful in training more culturally responsive teachers. In light of an increasingly diverse US student population versus a stagnantly homogeneous teaching workforce, his reflective practice will prove useful to teachers who are expected to teach students with cultures different from their own.

  18. Biomedical conflicts of interest: a defence of the sequestration thesis-learning from the cases of Nancy Olivieri and David Healy.

    2004-02-01

    No discussion of academic freedom, research integrity, and patient safety could begin with a more disquieting pair of case studies than those of Nancy Olivieri and David Healy. The cumulative impact of the Olivieri and Healy affairs has caused serious self examination within the biomedical research community. The first part of the essay analyses these recent academic scandals. The two case studies are then placed in their historical context-that context being the transformation of the norms of science through increasingly close ties between research universities and the corporate world. After a literature survey of the ways in which corporate sponsorship has biased the results of clinical drug trials, two different strategies to mitigate this problem are identified and assessed: a regulatory approach, which focuses on managing risks associated with industry funding of university research, and a more radical approach, the sequestration thesis, which counsels the outright elimination of corporate sponsorship. The reformist approach is criticised and the radical approach defended. PMID:14872066

    This study aimed to determine the prevalence and reproductive impact of Neospora caninum in a herd of semi-free-ranging Père David's deer (Elaphurus davidianus) at a conservation facility, following a suspected abortion storm in 2008. Serum samples (n=103) collected from 60 individuals between 2002 and 2011 were evaluated using competitive ELISA for the detection of N. caninum-specific antibodies. Of the 103 samples, 73 (70.9 per cent) were positive for N. caninum antibodies, with a mean±sd competitive inhibition (CI) of 77.6±19.8 per cent. Thirty (29.1 per cent) samples were seronegative, with mean CI of 15.2±9.70 per cent. A significant negative linear relationship was noted between the proportion of seropositive animals and age (R2=0.228, P<0.001). Calving rates of adult females from 2005 to 2011 ranged from 15.4 per cent to 52 per cent (mean 35.5±11.3 per cent), and did not correlate with mean CI values (Spearman's rank correlation coefficient=0.072, P=0.878). While both horizontal and transplacental transmission are likely contributing to persistent herd seropositivity, the role of N. caninum in reproductive success in this and other populations of endangered ungulates remains to be explored.

    The Chemical Analysis Automation (CAA) project is developing standardized, software-driven, site-deployable robotic laboratory systems with the objective of lowering the per-sample analysis cost, decreasing sample turnaround time, and minimizing human exposure to hazardous and radioactive materials associated with DOE remediation projects. The first integrated system developed by the CAA project is designed to determine polychlorinated biphenyls (PCB) content in soil matrices. A demonstration and development testing of this system was conducted in conjuction with surface soil characterization activities at the David Witherspoon 1630 Site in Knoxville, Tennessee. The PCB system consists of five hardware standard laboratory modules (SLMs), one software SLM, the task sequence controller (TSC), and the human-computer interface (HCI). Four of the hardware SLMs included a four-channel Soxhlet extractor, a high-volume concentrator, a column cleanup, and a gas chromatograph. These SLMs performed the sample preparation and measurement steps within the total analysis protocol. The fifth hardware module was a robot that transports samples between the SLMs and the required consumable supplies to the SLMs. The software SLM is an automated data interpretation module that receives raw data from the gas chromatograph SLM and analyzes the data to yield the analyte information. The TSC is a software system that provides the scheduling, management of system resources, and the coordination of all SLM activities. The HCI is a graphical user interface that presents the automated laboratory to the analyst in terms of the analytical procedures and methods. Human control of the automated laboratory is accomplished via the HCI. Sample information required for processing by the automated laboratory is entered through the HCI. Information related to the sample and the system status is presented to the analyst via graphical icons.

    My interest in science started very early, probably with science-fiction books like the Tom Swift series, which are aimed at children. After brief stints in chemistry and engineering, I chose to study physics at Boston University because I found it the most challenging. I also had dreams of being an "inventor" and thought physics would give me an understanding of how things worked.

    I did mathematical physics because it was just what I was best at. I enjoyed it at school, so I applied to do it at Nottingham University. I fell into it, to be quite honest. Once at university, I struggled at first, partly because I found it quite difficult to combine studying with competing and training in sport, which is pretty much full time as well. But by the end of my university career, I had learned to be organized, and to manage my time pretty effectively, so I enjoyed it a lot more.

    Polls were taken at the Project Explorer meetings regarding flying without the radio experiment transmitting. The radio downlinks require extra coordination and are sensitive to certain payloads. The poll results were unanimous. The radio downlinks are vital in providing data on the health and status of the total experiments package, in real time, during the flight. The amateur radio operators, prepared to receive the downlinks and OSCAR-10 relays, revealed that there was enormous interest throughout the world, to participate. This sets the stage for the reflight opportunities which the GAS program has provided. Major activities, pertinent to the STS-41G flight preparations by the GAS #007 team and support group, are listed.

    2009-01-01

    Marshall Space Flight Center mobile communications platform designs for future lunar missions led to improvements to fleets of tactical robots now being deployed by U.S. Army. The Multi-function Agile Remote Control Robot (MARCbot) helps soldiers search out and identify improvised explosive devices. NASA used the MARCbots to test its mobile communications platform, and in working with it, made the robot faster while adding capabilities -- upgrading to a digital camera, encrypting the controllers and video transmission, as well as increasing the range and adding communications abilities. They also simplified the design, providing more plug-and-play sensors and replacing some of the complex electronics with more trouble-free, low-cost components. Applied Geo Technology, a tribally-owned corporation in Choctaw, Mississippi, was given the task of manufacturing the modified robots. The company is now producing 40 units per month, 300 of which have already been deployed overseas.

  8. Finite element (MARC) solution technologies for viscoplastic analyses

    Arya, V. K.; Thompson, Robert L.

    1988-01-01

    A need for development of realistic constitutive models for structural components operating at high temperatures, accompanied by appropriate solution technologies for stress/life analyses of these components is studied. Viscoplastic models provide a better description of inelastic behavior of materials, but their mathematical structure is very complex. The highly nonlinear and stiff nature of the constitutive equations makes analytical solutions difficult. Therefore, suitable solution, finite element or other numerical, technologies must be developed to make these models adaptable for better and rational designs of components. NASA-Lewis has developed several solution technologies and successfully applied them to the solution of a number of uniaxial and multiaxial problems. Some of these solution technologies are described along with the models and representative results. The solution technologies developed and presented encompass a wide range of models, such as, isotropic, anisotropic, metal matrix composites, and single crystal models.

  19. Experimenting with wires, batteries, bulbs and the induction coil: Narratives of teaching and learning physics in the electrical investigations of Laura, David, Jamie, myself and the nineteenth century experimenters. Our developments and instruments

    NASA Astrophysics Data System (ADS)

    Cavicchi, Elizabeth Mary

    Physics is conventionally taught as a fixed curriculum which students must master. This thesis changes that: curriculum emerges from what learners try and question in experiments they invent. The thesis narrates: three adult students exploring wires, batteries and bulbs with me as teacher; nineteenth century investigations of electromagnetism; my laboratory work replicating historic instruments. In each case, learning arose through activity with materials. Evidences of this are analyzed within narratives and reflections. I used teaching-research, a method developed by Duckworth from Piaget's clinical interviewing, to research and simultaneously extend students' evolving understandings. What I learned through questioning students informed my next interactions; what they learned extended their experimenting. Similarly, I researched historical accounts interactively: improvising experiments to develop my understandings. Studying my own learning deepened my interpretations of students' learning. My students Laura, David and Jamie experimented by: soldering bulbs to wires, making series and parallel circuits, inserting resistive wire that dimmed bulbs, conducting electricity through salt water They noticed bulb brightness and battery heat, compared electricity's paths, questioned how voltage and current relate. They inferred electricity's effects manifest magnitudes of material properties. They found their experiences while learning were inseparable from what they learned. I researched investigations connected with Cavendish's leather fish, Galvani's frogs, Schweigger's wire spiraled around a compass needle, Henry's electromagnets, Faraday's induction ring, induction devices of Page, Callan, Hearder. Experimentally, I made galvanometers, electromagnets, induction rings, induction coil. I observed effects of electromagnetism, internal resistance, induced sparking. Across these investigations, learning developed with instrumental innovations; confusions were productive

  20. Hepatozoon cf. terzii (Sambon & Seligman, 1907) infection in the snake boa constrictor constrictor from north Brazil: transmission to the mosquito Culex quinquefasciatus and the lizard Tropidurus torquatus.

    PubMed

    Paperna, I; Lainson, R

    2004-06-01

    Specimens of Hepatozoon-infected Boa constrictor constrictor were obtained from localities in Pará State, north Brazil. Gametocytes in erythrocytes of the peripheral blood measured 10 x 2.5-16.2 x 3.7 microns. They were similar to those described as Haemogregarina terzii by Sambon & Seligmann (1907) in B. c. constrictor, in that they did not distort the infected erythrocyte, and their dimensions approximated those given by Carini (1947). Lungs and liver of infected snakes contained actively dividing meronts of a single type, and cysts containing two to six cystozoites were also present in the liver. Our initial feeding of Culex quinquefasciatus on infected snakes consistently resulted in a heavy death-rate of the engorged mosquitoes, with only a few surviving till the 9th day post feeding. These contained numerous oocysts which were undivided or in early stages of division. A fifth and final experiment, however, provided a few mosquitoes surviving up to 21 days post infection (dpi), and these contained fully sporulated oocysts measuring 190-200 microns in diameter and containing over 60 sporocysts of 19-30 microns in diameter. The number of sporozoites in each sporocyst was estimated as approximately 50. The nature of the parasite's sporogonic cycle in the mosquito thus justifies inclusion of this haemogregarine in the genus Hepatozoon. Two wild-caught specimens of the lizard Tropidurus torquatus were fed with mosquitoes containing fully developed oocysts (21 dpi). When sacrificed, three months later, large numbers of dizoic, tetrazoic and hexazoic cysts were demonstrated in their livers. Cystozoites released from these cysts were shown to possess a conspicuous refractile body. PMID:15224579

    The northern continental slope off the Ebro Delta has a badland topography indicating major slope erosion and mass movement of material that deposits sediment into a ponded lobe. The southern slope has a low degree of mass movement activity and slope valleys feed channel levee-complexes on a steep continental rise. The last active fan valley is V-shaped with little meandering and its thalweg merges downstream with the Valencia Valley. The older and larger inactive channel-levee complex is smoother, U-shaped, and meanders more than the active fan valley. ?? 1985 Springer-Verlag New York Inc.

    2015-02-01

    The Biochemical Methane Potential (BMP) of winery organic waste, with reference to two Italian red and white grapes (i.e. Nero Buono and Greco) by-products was investigated. The study was carried out to verify the possibility to reduce the production impact in a green-waste-management-chain-perspective. The possibility to efficiently utilize wine-related-by-products for energy production at a micro-scale (i.e. small-medium scale winery production plant) was also verified. Results showed as a good correlation can be established between the percentage of COD removal and the biogas production, as the winery can produce, from its waste methanization, about 7800 kW h year(-1) electrical and 8900 kW h year(-1) thermal. A critical evaluation was performed about the possibility to utilize the proposed approach to realize an optimal biomass waste management and an energetic valorization in a local-energy-production-perspective.

    1994-01-01

    During 1991, the Space Simulation Facility conducted a survey to assess the requirements and analyze the merits for purchasing a new thermal vacuum data processing system for its facilities. A new, integrated, cost effective PC-based system was purchased which uses commercial off-the-shelf software for operation and control. This system can be easily reconfigured and allows its users to access a local area network. In addition, it provides superior performance compared to that of the former system which used an outdated mini-computer and peripheral hardware. This paper provides essential background on the old data processing system's features, capabilities, and the performance criteria that drove the genesis of its successor. This paper concludes with a detailed discussion of the thermal vacuum data processing system's components, features, and its important role in supporting our space-simulation environment and our capabilities for spacecraft testing. The new system was tested during the ANIK E spacecraft test, and was fully operational in November 1991.

    NASA Astrophysics Data System (ADS)

    Borucki, William J.

    2013-01-01

    Dave worked on scientific space instrumentation since the Apollo era in the mid-1960s. He was born and raised in Milwaukee, WI, and attended Milwaukee Lutheran High School where he built a Michelson interferometer that proved to be a stepping-stone for his interest in physics. Dave graduated from the University of Wisconsin-Madison, where he earned a Bachelor of Science in applied mathematics and engineering physics in 1967. As an undergraduate, he worked on balloon-launched sounding rockets and scientific instruments in X-ray and gamma-ray astronomy. At Cornell University, Dave earned a master's degree in 1971, and a doctorate in 1972, both in physics. He built a balloon-borne gamma-ray telescope that detected the first pulsed high-energy gamma rays from the Crab pulsar. In 1972, Dave began his career at American Science and Engineering where he was the project scientist for the Uhuru X-ray satellite. Later, he served as the project scientist for the development of the Einstein Observatory. Dave joined the Smithsonian Center for Astrophysics in 1977 as the project scientist for the Spacelab-2 infrared telescope. There, he served as a co-investigator on the Space Infrared Telescope Facility - IRAC camera proposal, and co-investigator on the Submillimeter Wave Astronomy Satellite, which launched in December 1998. Dave came to NASA Ames Research Center to lead the mission operations for SIRTF and SOFIA (Stratospheric Observatory for Infrared Astronomy) in 1988. He created the Flight Opportunities for Science Teacher EnRichment project. In 1992, Dave began working on what has become the Kepler mission, for which he served as deputy principal investigator until retiring in August 2011. Dave's contributions were many but most notably, he led the development of the Kepler Technology Demonstration used to prove that the transit photometry method would work under on-orbit conditions. Dave loved to build things and was passionate about engaging young hearts and minds with the excitement of science and space exploration. He was particularly fond of educating and empowering teachers with the right tools to connect with the formal and informal classroom.

    D.D. Palmer has been a much ignored man in the discipline he founded. The same applies to several early concepts he used to develop from a mere healer's background: D.D. Palmer invested them with an entirely different meaning. When considered, they help to understand the inner logic that allowed for chiropractic survival. There was an alchemy in the creation of chiropractic and the senior Palmer was the alchemist. He has not been recognized even within his own profession for the self-taught scholar and clinician that he was, knowledgeable about the various medical and scientific theories of his time.

    2003-01-01

    The chemico-medical essay "De sale lactis essentiali" is a thesis presented in Leyden in 1756 by a physician from Lausanne, M.-L. Vullyamoz, to obtain the medical degree. It shows that chemistry has become a university science connected with medicine and that combustion was explained at that time by G. E. Stahl's theory of the phlogiston. It reminds us that the hypotheses of this German physician, which were part of the animistic doctrine, were widely adopted in Europe. In chemistry they began to fade in 1789 after the publication of Lavoisier's work on oxydation. Nevertheless, they have contributed to establish a modern science. In medicine Stahl's animism evolved towards vitalism, which survived in several forms. Vullyamoz's thesis, which presents chemical experiences intended to analyse and promote a popular medicine, is a testimony of the spirit of Enlightenment, which rejects dogmatism and tries to understand facts through observation and the use of reason.

    The Maule (Mw8.8 27/02/2010), Darfield (Mw7.1 04/09/2010), Lyttelton (Mw6.3 22/02/2011) and Tohoku (Mw9.0 06/04/2011) events proved that, even if earthquake engineering, and all the related research fields, tackle efficiently the challenge of earthquake catastrophes, nonetheless the fragility of modern society is still quite high. How to work toward building an earthquake resilient society seems to be the next defiance. Furthermore, the major events of the last two years reminded us dramatically that the reliable assessment of earthquake-induced damages and losses is a problem of paramount importance. The comparison between extremely different events, both in size of the event and in insurance penetration condition, allows us to further reflect on the way how risk is presently addressed. In this contribution we will first summarize our recent findings on the Maule event and on the Christchurch seismic sequence (September 2010 - June 2011), partly based on 3D numerical modeling of earthquake ground shaking, with particular consideration of the comparison between observed and simulated waveforms (Guidotti et al.). Taking advantage of the lessons learnt from the Maule event in terms of vulnerability of the Chilean building stock, we will then show the numerical results obtained for a set of 3D deterministic fault rupture scenarios, occurring along the San Ramon fault, located on the eastern margin of the city of Santiago de Chile (Pilz et al.). Notwithstanding their low probability, "Christchurch-like" seismic events are not isolated cases. They deserve special attention and form an important element in overall risk management approach, allowing us to draw some conclusions about the future development of this topic and about the role of numerical simulations in seismic hazard assessment studies.

  4. David Adler Lectureship Award: n-point Correlation Functions in Heterogeneous Materials.

    NASA Astrophysics Data System (ADS)

    Torquato, Salvatore

    2009-03-01

    The determination of the bulk transport, electromagnetic, mechanical, and optical properties of heterogeneous materials has a long and venerable history, attracting the attention of some of the luminaries of science, including Maxwell, Lord Rayleigh, and Einstein. The bulk properties can be shown to depend rigorously upon infinite sets of various n-point correlation functions. Many different types of correlation functions arise, depending on the physics of the problem. A unified approach to characterize the microstructure and bulk properties of a large class of disordered materials is developed [S. Torquato, Random Heterogeneous Materials: Microstructure and Macroscopic Properties (Springer-Verlag, New York, 2002)]. This is accomplished via a canonical n-point function Hn from which one can derive exact analytical expressions for any microstructural function of interest. This microstructural information can then be used to estimate accurately the bulk properties of the material. Unlike homogeneous materials, seemingly different bulk properties (e.g., transport and mechanical properties) of a heterogeneous material can be linked to one another because of the common microstructure that they share. Such cross-property relations can be used to estimate one property given a measurement of another. A recently identified decorrelation principle, roughly speaking, refers to the phenomenon that unconstrained correlations that exist in low-dimensional disordered materials vanish as the space dimension becomes large. Among other results, this implies that in sufficiently high dimensions the densest spheres packings may be disordered (rather than ordered) [S. Torquato and F. H. Stillinger, ``New Conjectural Lower Bounds on the Optimal Density of Sphere Packings," Experimental Mathematics, 15, 307 (2006)].

    2011-03-01

    Recent progress in development of GaN-based transistors for gas and bio-sensing applications and amorphous IGZO layers for use thin film transistors (TFTs)on flexible substrates, including paper,will be presented. For the detection of gases such as hydrogen, the gateless GaN transistors are typically coated with a catalyst metal such as Pd or Pt to increase the detection sensitivity at room temperature. Functionalizing the surface with oxides, polymers and nitrides is also useful in enhancing the detection sensitivity for gases and ionic solutions.The use of enzymes or adsorbed antibody layers on the semiconductor surface leads to highly specific detection of a broad range of antigens of interest in the medical and security fields. We give examples of recent work showing sensitive detection of glucose, lactic acid, prostate cancer and breast cancer markers and the integration of the sensors with wireless data transmission systems to achieve robust, portable sensors. The amorphous transparent conducting oxide InZnGaO4 (IGZO) is attracting attention because of its high electron mobility (10-50 cm2.V-1.sec-1), high transparency in the visible region of the spectrum and its ability to be deposited with a wide range of conductivities.This raises the possibility of making low-cost electronics on a very wide range of arbitrary surfaces, including paper and plastics. N-type oxides such as zinc oxide, zinc tin oxide, indium gallium oxide, and indium gallium zinc tin oxide (IGZO) exhibit surprisingly high carrier mobilities even for amorphous films deposited at 300K. This has been explained by the fact that the conduction in these materials is predominantly through non-directional s orbitals which are less affected by disorder than the directional sp3 orbitals which control electron transport in Si. Examples of progress and discussion of remaining obstacles to use of IGZO TFTs will be presented Work performed in collaboration with Fan Ren.

    2015-01-01

    London (2014) provides an interesting article which presents a study of pegmatite zonation which is of considerable interest to students of pegmatites. However, although there is much to recommend it we take exception to his attempts to dismiss an extensive body of work on the use of melt inclusions to address the critical question of actual melt compositions during the evolution of pegmatites. Volatiles are by definition fugitive, since they are readily lost by degassing, and yet they are clearly critical to the growth of the large crystals which are a defining characteristic of pegmatites (e.g. Bartoli et al., 2014; Bowen, 1956; London, 2008; Lowenstern, 2003). Any research technique which can address the pre-degassing melt compositions should therefore be considered on its merits. Although melt inclusion studies are of relatively recent vintage the problems and possible questions of interpretation have been addressed in considerable detail for at least the last two decades (e.g. Lowenstern, 2003, and references therein) and recently in Audétat and Lowenstern (2014). Likewise, any discussion needs to cover "simple" quartz-feldspar-muscovite pegmatites (e.g. Thomas et al., 2009b), as well as the much less common if more interesting rare-element rich pegmatites (e.g. Thomas et al., 2009a).

    2006-01-01

    Most CEOs who specialize in turning around struggling companies focus on costs. But for Fred Hassan, chairman and CEO of Schering-Plough, the primary focus in a turnaround is the top line. Since 2003, when Hassan took the helm at the global pharmaceutical company, he has overseen a remarkable recovery in performance. And consistent with his philosophy, the turnaround started with sales. Considering sales reps as less than crucial to strategy, Hassan cautions, is a big mistake. At Schering-Plough, he has concentrated on motivating and organizing salespeople to create trusting relationships with doctors. "You have to differentiate the salesperson in the customer's mind--just like you differentiate brands," he explains. A doctor may see 60 pharmaceutical reps on a regular basis but actually trust far fewer. To earn a spot in this inner circle, Schering-Plough reps try to turn each customer encounter into an occasion to help doctors provide better care for their patients. Schering-Plough also restructured its sales forces so that reps carry not just one kind of product, as they do in most pharmaceutical companies, but several. Covering a broad range of treatments gives reps more ways to build value-adding relationships with doctors. In this interview, Hassan discusses his success at Schering-Plough and his experiences at other pharmaceutical companies. During his career, he has built a reputation for being in tune with the front lines, as well as for reaching out to the managers who supervise salespeople. He has found that this level of personal attention not only makes reps feel respected but also gives him valuable strategic insights. PMID:16846192

    NASA Technical Reports Server (NTRS)

    2003-01-01

    With the renewed interest in Cartesian gridding methodologies for the ease and speed of gridding complex geometries in addition to the simplicity of the control volumes used in the computations, it has become important to investigate ways of extending the existing Cartesian grid solver functionalities. This includes developing methods of modeling the viscous effects in order to utilize Cartesian grids solvers for accurate drag predictions and addressing the issues related to the distributed memory parallelization of Cartesian solvers. This research presents advances in two areas of interest in Cartesian grid solvers, viscous effects modeling and MPI parallelization. The development of viscous effects modeling using solely Cartesian grids has been hampered by the widely varying control volume sizes associated with the mesh refinement and the cut cells associated with the solid surface. This problem is being addressed by using physically based modeling techniques to update the state vectors of the cut cells and removing them from the finite volume integration scheme. This work is performed on a new Cartesian grid solver, NASCART-GT, with modifications to its cut cell functionality. The development of MPI parallelization addresses issues associated with utilizing Cartesian solvers on distributed memory parallel environments. This work is performed on an existing Cartesian grid solver, CART3D, with modifications to its parallelization methodology.

    2013-10-01

    The past century had witnessed vast advances in biomedical research, particularly in the fields of genomics and proteomics, yet the translation of these discoveries into clinical practice has been hindered by gaps in mechanistic understanding of variability governing disease susceptibility and pathogenesis. Among the greatest challenges are the dynamic nature of the proteome and the imperfect methodologies currently available to study it. Here, we review key recently developed proteomic techniques that have allowed for dynamic characterization of protein quality, as well as quantity, and discuss their potential applications in understanding aging and metabolic disorders including diabetes. These methodologies revealed that senescence is characterized, in part, by decreased rates of de novo protein synthesis and potentially also degradation, in addition to concomitantly increased levels of oxidative stress, ultimately resulting in excessive accumulation of damaged and dysfunctional proteins. Insulin may be a key mediator in these pathologies, as hyperinsulinemia has been shown to hinder protein degradation while transient insulin deficiency may accelerate oxidative damage. We also discuss two interventions that have been proposed to delay, and possibly reverse, senescence by augmenting protein degradation: chronic caloric restriction and aerobic exercise.

    We first review the current state-of-the-art in the field of organic electronics and then focus on organic solar cells, which we define as solid-state cells in which the semiconducting materials between the electrodes are organic, be them polymers, oligomers, or small molecules. We describe the optical and electronic processes that take place in such cells and turn our attention briefly to: (i) optical absorption and exciton formation; (ii) exciton migration to the electron donor - electron acceptor interface; (iii) exciton dissociation into charge carriers, resulting in the appearance of holes in the donor component and electrons in the acceptor component; (iv) charge carrier mobility; and (v) charge collection at the electrodes. In the second part of the presentation, we underline the complexity of the processes taking place at the nanoscale at the donor/acceptor interfaces and highlight the molecular understanding that comes from a computational approach combining electronic-structure theory calculations, molecular mechanics / molecular dynamics simulations, and Monte Carlo simulations.

    Quasiperiodic order is recognized (in a utilitarian, rather than a mathematical sense) by the absence of periodicity, concurrent with a classically-forbidden rotational symmetry. It is quite beautiful, having captured the attention of scientists and artists alike. Following the discovery of quasiperiodic order in a real system,footnotetextD. Shechtman, I. Blech, D. Gratias, and J.W. Cahn, Phys. Rev. Lett. 53, 1951 (1984). many metallic alloys and intermetallics were found to exhibit this type of order on the atomic scale. More recently ``soft'' quasicrystals were discovered,footnotetextL. Bindi, P.J. Steinhardt, N. Yao, and P.J. Lu, Science 324, 1306 (2009). and nanocrystalline arrays were found to spontaneously adopt quasiperiodic order.footnotetextD.V. Talapin, E.V. Shevchenko, M.I. Bodnarchuk, X. Ye, J. Chen, and C.B. Murray, Nature 461 , 964 (2009). From a scientific perspective, quasicrystals are alluring because they allow us to test the relationship between atomic structure and physical properties. This talk deals with the ways in which our understanding of solid surfaces has been both enriched and challenged by these complex materials.footnotetextP. Thiel, Annu. Rev. Phys. Chem.

Dubois, Useful Quasicrystals(World Scientific, Singapore, 2005). For instance, among Al-rich alloys, the Al-based quasicrystalline phases exhibit puzzling resistance to surface oxidation. Also, Al-rich quasicrystals have surprisingly good and promising catalytic properties (e.g. for steam reforming of methanol).footnotetextA.P. Tsai and M. Yoshimura, Appl. Cat. A: General 214 , 237 (2001). Perhaps most famously, they exhibit low friction.^7 Comparisons with crystalline materials have established that these features are deeply related to the quasiperiodic atomic structure. talk focuses, first, on the ways that surfaces of quasicrystals are unusual templates for adsorption and solid film growth.footnotetextV.

The electronic structure at quasicrystal surfaces can affect film morphology through a quantum size effect.footnotetextV. Fourn'ee, H.R. Sharma, M. Shimoda, A.P. Tsai, B. Unal, A.R. Ross, T.A.

    The exhibition held in Paris commemorating the bicentenial of Heinrich Heine showed three prescriptions by Dr. D. Gruby, through which morphine was prescribed for the poet by external route. The use of morphine was justified in a patient with unrelieved pain caused by neurosyphilis during the last twelve years of his life. This way of morphine administration (endemic method) was quite popular between 1830 and 1860.

  7. A David and Goliath story: tobacco advertising and self-regulation in Australia.

    PubMed Central

    Chapman, S

    1980-01-01

    A small group of health workers succeeded in getting the largest tobacco advertising campaign in Australia banned by testing a clause in the advertising industry's voluntary code of self-regulation. The group complained about a series of cigarette advertisements that featured an Australian entertainer who was popular with the young. Though the tobacco company denied the entertainer's major appeal to the young, the chairman of the Advertising Standards Council ruled that the campaign did breach the code. The delay before the complaint was adjudicated--18 months--contrasted with the speed with which a series of antismoking advertisements had been withdrawn after complaints by a tobacco company's advertisers. MOP UP's victory in this case contains several lessons for people interested in restricting the promotional activities of multinational tobacco companies. Images FIG 1 FIG 2 PMID:7427631

  10. David Adler Award Talk: Half-Metals, Spin Torque, and Nanorings

    NASA Astrophysics Data System (ADS)

    Chien, C. L.

    2004-03-01

    New phenomena in magnetic nanostructures, some of which have led to important technological applications in magnetoelectronics, have been realized in rapid succession in recent years. Several examples will be described in this talk. While most ferromagnetic metals are partially spin-polarized, the half-metallic ferromagnets (HMF) with only one spin band at the Fermi energy have the highest possible spin polarization of 100%. Although HMFs were theoretically predicted in 1983, they were not experimentally identified until recently using the few techniques with which the spin polarization of a metal can be determined. A spin-polarized current with its substantial angular momentum can cause spin precession and even switching in a receiving ferromagnetic entity. Aspects of the spin torque effect, as observed in continuous multilayered films as well as single-layer ferromagnetic films with a point contact, will be described. Magnetic nanorings have been proposed theoretically to alleviate problems due to the singularity at the center of a small ferromagnetic disc in the vortex state. Previous attempts on nanorings using e-beam lithography have been limited by the small number of rings of relatively large diameters ( ˜1 μm). Recently, we have developed a new lithography-less method for making arrays of a large number (10^9) of sub-100 nm nanorings, either single-layer or multilayered, with very high areal density (45 rings/μm^2). Some of the results of arrays of Co nanorings will be described. *I am very fortunate to be working with talented students and post-docs (F. Y. Yang now at Ohio State University, Y. Ji now at Argonne National Lab., G. Strijkers now at Einhoven Institute of Technology, Q. Zhu, D. L. Fan, and T. Y. Chen), some of whose results are included here. I am also indebted to G.

    2013-01-01

    The neoclerodane diterpene salvinorin A is the major active component of the hallucinogenic mint plant Salvia divinorum Epling & Játiva (Lamiaceae). Since the finding that salvinorin A exerts its potent psychotropic actions through the activation of opioid receptors, the site of action of morphine and related analogues, there has been much interest in elucidating the underlying mechanisms behind its effects. These effects are particularly remarkable, because (1) salvinorin A is the first reported non-nitrogenous opioid receptor agonist, and (2) its effects are not mediated through the previously investigated targets of psychotomimetics. This perspective outlines our research program, illustrating a new direction to the development of tools to further elucidate the biological mechanisms of drug tolerance and dependence. The information gained from these efforts is expected to facilitate the design of novel agents to treat pain, drug abuse, and other CNS disorders. PMID:23548164

  15. Can David and Goliath Get Along? Federal Land in Local Places

    2001-12-01

    It is often unclear what the role of a local jurisdiction is with regard to land use management on nearby federal properties. Yet federal lands clearly impact nearby local communities. The US Department of Energy (DOE), with over 100 sites across the United States with varying degrees of environmental contamination, may be in a very difficult position with regard to relationships with local government about land use. Yet few, if any, studies have examined DOE land use issues. This study asks: (1) In general, how do local planners feel about federal government relationships with them? (2) Do local planners feel differently about the DOE than they do about other federal agencies? (3) What reasons explain any differences observed in answer to the second question? To answer these questions, local planners were interviewed from communities adjacent to non-DOE federal properties, and their responses compared to those of planners located near DOE facilities in the same regions. Findings showed that compared to other federal agencies that own land in the same regions, the DOE is relatively poorer at actively involving local officials in land use decisions at its sites. Primary reasons are the historic legacy of a culture of secrecy, focus on mission, and especially the lack of experience, training, or mandates in local planning cooperation. Findings also suggest that this attitude is markedly stronger in areas west of the Rocky Mountains. Recommendations for improved federal-local communications include the development of a vision for local government involvement that is supported by top levels of management and filtered effectively to the site level.

    2012-03-01

    Proper illumination is essential for light microscopy. Whereas in early years incandescent light was the only illumination, today, more and more specialized light sources, such as lasers or arc lamps are used. Because of the high efficiency and brightness that light-emitting diodes (LED) have reached today, they have become a serious alternative for almost all kinds of illumination in light microscopy. LED have a high durability, do not need expensive electronics, and they can be switched in nanoseconds. Besides this, they are available throughout the UV/Vis/NIR-spectrum with a narrow bandwidth. This makes them ideal light sources for fluorescence microscopy. The white LED, with a color temperature ranging from 2,600 up to 5,000 K is an excellent choice for bright-field illumination with the additional advantage of simple brightness adjustments without changing the spectrum. This review discusses the different LED types, their use in the fluorescence microscope, and discusses LED as specialized illumination sources for Förster resonance energy transfer and fluorescent lifetime imaging microscopy.

  20. Building virtual planets with global climate models: a scientific endeavour (David Bates Medal Lecture)

    NASA Astrophysics Data System (ADS)

    Forget, Francois

    2014-05-01

    On the basis of the Global Climate Models (GCMs) originally developed for the Earth, it has been possible to develop GCMs for the other terrestrial environments in our solar system: Venus, Mars, Titan, Triton and Pluto. The ambition behind the development of GCMs is high: the ultimate goal is to build numerical simulators only based on universal physical or chemical equations, yet able to reproduce or predict all the available observations on a given planet, without any ad-hoc forcing. In other words, we aim at creating in our computers virtual planets "behaving" exactly like the actual planets. In reality of course, nature is always more complex than expected, but we learn a lot in the process. On the basis of our experience in the solar system, we can also envisage to build realistic climate models to predict the environment on any terrestrial planets that we can imagine. Such a tool is useful for conducting scientific investigations on the possible climates on terrestrial extrasolar planets, or to study past environments in the solar system. Can we trust such a model when no direct observation is available? In this talk, I will review the lessons learned from the modelling of observable planets, the successes and failures of GCMs, and present recent and exotic applications.

    The primary objective of the independent verification was to determine if BJC performed the appropriate actions to meet the specified “hot spot” cleanup criteria of 500 picocuries per gram (pCi/g) uranium-238 (U-238) in surface soil. Specific tasks performed by the independent verification team (IVT) to satisfy this objective included: 1) performing radiological walkover surveys, and 2) collecting soil samples for independent analyses. The independent verification (IV) efforts were designed to evaluate radioactive contaminants (specifically U-238) in the exposed surfaces below one foot of the original site grade, given that the top one foot layer of soil on the site was removed in its entirety.

    It is rare to find a true predator that repeatedly and routinely kills prey larger than itself. A solitary specialised ant-eating spider of the genus Zodarion can capture a relatively giant prey. We studied the trophic niche of this spider species and investigated its adaptations (behavioural and venomic) that are used to capture ants. We found that the spider captures mainly polymorphic Messor arenarius ants. Adult female spiders captured large morphs while tiny juveniles captured smaller morphs, yet in both cases ants were giant in comparison with spider size. All specimens used an effective prey capture strategy that protected them from ant retaliation. Juvenile and adult spiders were able to paralyse their prey using a single bite. The venom glands of adults were more than 50 times larger than those of juvenile spiders, but the paralysis latency of juveniles was 1.5 times longer. This suggests that this spider species possesses very potent venom already at the juvenile stage. Comparison of the venom composition between juvenile and adult spiders did not reveal significant differences. We discovered here that specialised capture combined with very effective venom enables the capture of giant prey.

    Given the lack of a standardized approach to medical student global health predeparture preparation, we evaluated an in-person, interactive predeparture orientation (PDO) at the University of California Los Angeles (UCLA) to understand program strengths, weaknesses, and areas for improvement. We administered anonymous surveys to assess the structure and content of the PDO and also surveyed a subset of students after travel on the utility of the PDO. We used Fisher's exact test to evaluate the association between prior global health experience and satisfaction with the PDO. One hundred and five students attended the PDO between 2010 and 2014 and completed the survey. One hundred and four students (99.0%) reported learning new information. Major strengths included faculty mentorship (N = 38, 19.7%), opportunities to interact with the UCLA global health community (N = 34, 17.6%), and sharing global health experiences (N = 32, 16.6%). Of students surveyed after their elective, 94.4% (N = 51) agreed or strongly agreed that the PDO provided effective preparation. Students with prior global health experience found the PDO to be as useful as students without experience (92.7% versus 94.4%, P = 1.0). On the basis of these findings, we believe that a well-composed PDO is beneficial for students participating in global health experiences and recommend further comparative studies of PDO content and delivery.

  14. Economic Efficiency and Equity in Dams Removal: Case studies in Northeastern Massachusetts Doina Oglavie, Ellen Douglas, David Terkla

    NASA Astrophysics Data System (ADS)

    Oglavie, D. R.; Douglas, E. M.; Terkla, D.

    2009-12-01

    According to American Rivers (www.americanrivers.org), Massachusetts has almost 3,000 dams under state regulation, 296 of which have been classified as high hazard, meaning they pose a serious threat to human life if they should fail. Most of these dams, however, are low head, “run-of-the-river” dams that no longer serve the purpose for which they were built. The presence of these dams has fragmented aquatic and riparian ecosystems, impeded fish passage and generally impacted the natural ecological and hydrological functioning of the streams in which they reside. Dam removal should be considered when a dam no longer serves its function. Although in many cases, the removal of a dam is environmentally beneficial (at least over the long term), sometimes the removal of a dam can incur environmental costs, such as release of contaminants that were sequestered behind the dam. Dam removal is a complex issue especially with respect to privately owned dams. In many cases, dam removal is less costly than dam maintenance or upgrade, hence dam removal decisions tend to be based on purely monetary considerations, and the environmental costs or benefits associated with the dam are not considered. Typically, the main objective for the dam owner is to incur the lowest possible cost (private cost), whether it be operating and maintenance or removal; external costs (environmental degradation) are rarely, if ever, considered, hence the true cost to society is not included in the economic analysis. If dam operation and removal decisions are to be economically efficient, then they have to include both the private costs as well as the external (environmental) costs. The purpose of this work is to 1) attempt to quantify the externalities associated with the maintenance and the removal of dams, 2) assess whether or not the current dam removal evaluation process maximizes social welfare (efficiency and equity) and 3) suggest ways in which this process can be improved by including the identified externalities. Economic efficiency occurs when the greatest total social value is obtained for the least possible social cost. Equity is related to the fair and just distribution of benefits and costs among individuals and society. Our first evaluation looked at the decisions made with respect to two dams situated on the Ipswich River in northeastern Massachusetts: Bostik Dam and EBSCO Dam. The Bostik Dam provides water storage for nearby industrial facilities. It is the third dam on the main stem of the Ipswich River and is the most downstream dam without provisions for fish passage. The EBSCO Dam is the most downstream dam on the Ipswich River and presently has no functional use. After several meetings between owners, residents, and agencies involved in the process, the final decision was to remove the Bostik Dam. However, our preliminary analysis indicated that it would be more economically efficient and equitable to remove the EBSCO Dam instead. The next step in our project will be refine our economical analysis of these dams and apply our methods to other dams slated for removal in northeastern Massachusetts.

  15. David Adler Lectureship Award Talk: Friction and energy dissipation mechanisms in adsorbed molecules and molecularly thin films

    NASA Astrophysics Data System (ADS)

    Krim, Jacqueline

    2015-03-01

    Studies of the fundamental origins of friction have undergone rapid progress in recent years, with the development of new experimental and computational techniques for measuring and simulating friction at atomic length and time scales. The increased interest has sparked a variety of discussions and debates concerning the nature of the atomic-scale and quantum mechanisms that dominate the dissipative process by which mechanical energy is transformed into heat. Measurements of the sliding friction of physisorbed monolayers and bilayers can provide information on the relative contributions of these various dissipative mechanisms. Adsorbed films, whether intentionally applied or present as trace levels of physisorbed contaminants, moreover are ubiquitous at virtually all surfaces. As such, they impact a wide range of applications whose progress depends on precise control and/or knowledge of surface diffusion processes. Examples include nanoscale assembly, directed transport of Brownian particles, material flow through restricted geometries such as graphene membranes and molecular sieves, passivation and edge effects in carbon-based lubricants, and the stability of granular materials associated with frictional and frictionless contacts.

  20. When David beats Goliath: the advantage of large size in interspecific aggressive contests declines over evolutionary time.

    PubMed

    Martin, Paul R; Ghalambor, Cameron K

    2014-01-01

    Body size has long been recognized to play a key role in shaping species interactions. For example, while small species thrive in a diversity of environments, they typically lose aggressive contests for resources with larger species. However, numerous examples exist of smaller species dominating larger species during aggressive interactions, suggesting that the evolution of traits can allow species to overcome the competitive disadvantage of small size. If these traits accumulate as lineages diverge, then the advantage of large size in interspecific aggressive interactions should decline with increased evolutionary distance. We tested this hypothesis using data on the outcomes of 23,362 aggressive interactions among 246 bird species pairs involving vultures at carcasses, hummingbirds at nectar sources, and antbirds and woodcreepers at army ant swarms. We found the advantage of large size declined as species became more evolutionarily divergent, and smaller species were more likely to dominate aggressive contests when interacting with more distantly-related species. These results appear to be caused by both the evolution of traits in smaller species that enhanced their abilities in aggressive contests, and the evolution of traits in larger species that were adaptive for other functions, but compromised their abilities to compete aggressively. Specific traits that may provide advantages to small species in aggressive interactions included well-developed leg musculature and talons, enhanced flight acceleration and maneuverability, novel fighting behaviors, and traits associated with aggression, such as testosterone and muscle development. Traits that may have hindered larger species in aggressive interactions included the evolution of morphologies for tree trunk foraging that compromised performance in aggressive contests away from trunks, and the evolution of migration. Overall, our results suggest that fundamental trade-offs, such as those associated with body size, are more likely to break down over evolutionary time, changing the rules that govern species interactions and structure ecological communities.
