  2. The Legacy of Seligman's "Phobias and Preparedness" (1971).

    PubMed

    McNally, Richard J

    2016-09-01

    Seligman's (1971) classic article, "Phobias and Preparedness," marked a break from traditional conditioning theories of the etiology of phobias, inspiring a line of research integrating evolutionary theory with learning theory. In this article, I briefly sketch the context motivating the preparedness theory of phobias before summarizing the initial wave of laboratory conditioning experiments pioneered by Öhman and conducted by his team and by others to test predictions derived from Seligman's theory. Finally, I review the legacy of Seligman's article, including theoretical developments embodied in Öhman and Mineka's fear module approach as well as alternatives for explaining "preparedness" phenomena, including the selective sensitization, expectancy, and nonassociative theories. Although Seligman himself soon moved on to other topics, his seminal article in Behavior Therapy continues to inspire research more than four decades later that has deepened our understanding of the etiology of phobias.

    Mongrain, Myriam; Anselmo-Matthews, Tracy

    2012-04-01

    The current work replicated a landmark study conducted by Seligman and colleagues (2005) that demonstrated the long-term benefits of positive psychology exercises (PPEs). In the original study, two exercises administered over 1 week ("Three Good Things" and "Using your Signature Strengths in a New Way") were found to have long-lasting effects on depression and happiness (Seligman, Steen, Park, & Peterson, 2005). These exercises were tested here using the same methodology except for improvements to the control condition, and the addition of a second "positive placebo" to isolate the common factor of accessing positive, self-relevant constructs. This component control design was meant to assess the effect of expectancies for success (expectancy control), as well the cognitive access of positive information about the self (positive placebo). Repeated measures analyses showed that the PPEs led to lasting increases in happiness, as did the positive placebo. The PPEs did not exceed the control condition in producing changes in depression over time. Brief, positive psychology interventions may boost happiness through a common factor involving the activation of positive, self-relevant information rather than through other specific mechanisms. Finally, the effects of PPEs on depression may be more modest than previously assumed. © 2012 Wiley Periodicals, Inc.

  17. Toxicity of sulcotrione and grape marc on Vicia faba cells.

    PubMed

    Sta, Chaima; Goujon, Eric; Ferjani, Ezzeddine; Ledoigt, Gérard

    2014-12-10

    The cell toxicity of sulcotrione, a selective triketone herbicide, was evaluated on Vicia faba. Sulcotrione, trademark Mikado, grape marc, and mixtures of sulcotrione or Mikado with grape marc induced cell death. Addition of grape marc to either sulcotrione or Mikado enhanced cell death, especially with Mikado. Addition of grape marc to herbicides, sulcotrione, or Mikado resulted in different expression of genes usually associated with cell stress. Mixtures of grape marc and herbicides enhanced transcript accumulation for ubiquitin, hsp 70, and cytosolic superoxide dismutase, but did not change ascorbate peroxidase transcript accumulation. The results thus provide evidence that sulcotrione, Mikado, and mixtures with grape marc can trigger cell death and specific gene expressions. Cocktails of products with sulcotrione, such as commercial additives and grape marc, can modify biological features of pesticide. Moreover, grape marc differently enhanced cell toxicity of sulcotrione and Mikado, suggesting a synergy between pesticide products and grape marc.

  20. Thermal degradation of grape marc polyphenols.

    PubMed

    Sólyom, Katalin; Solá, Ruth; Cocero, María José; Mato, Rafael B

    2014-09-15

    Bioactive compounds of wine making by-products are of interest in food, cosmetics and pharmaceutical industries. Extraction of antioxidants under mild conditions is time-consuming, giving ground to the development of intensification processes where the operation at high temperature may deteriorate extract quality. This study examined thermal degradation of grape marc and its filtered extract (80, 100 and 150°C). The decrease in anthocyanin content was modelled under non-isothermal conditions by first order kinetics, using the Arrhenius equation. Simulated degradation under isothermal heating showed that the grape marc is more sensitive by one order of magnitude to heat than the filtered extract. This tendency was also confirmed by analyses of the total phenolic content and antioxidant activity. It is suggested that an optimal combination of temperature, treatment time and also raw material environment could be found in process intensification. Copyright © 2014 Elsevier Ltd.

  14. The mammalian molybdenum enzymes of mARC.

    PubMed

    Ott, Gudrun; Havemeyer, Antje; Clement, Bernd

    2015-03-01

    The "mitochondrial amidoxime reducing component" (mARC) is the most recently discovered molybdenum-containing enzyme in mammals. All mammalian genomes studied to date contain two mARC genes: MARC1 and MARC2. The proteins encoded by these genes are mARC-1 and mARC-2 and represent the simplest form of eukaryotic molybdenum enzymes, only binding the molybdenum cofactor. In the presence of NADH, mARC proteins exert N-reductive activity together with the two electron transport proteins cytochrome b5 type B and NADH cytochrome b5 reductase. This enzyme system is capable of reducing a great variety of N-hydroxylated substrates. It plays a decisive role in the activation of prodrugs containing an amidoxime structure, and in detoxification pathways, e.g., of N-hydroxylated purine and pyrimidine bases. It belongs to a group of drug metabolism enzymes, in particular as a counterpart of P450 formed N-oxygenated metabolites. Its physiological relevance, on the other hand, is largely unknown. The aim of this article is to summarize our current knowledge of these proteins with a special focus on the mammalian enzymes and their N-reductive activity.

  15. David Hartley's Newtonian neuropsychology.

    PubMed

    Smith, C U

    1987-04-01

    David Hartley's association psychology has been immensely influential. His vibrationist neurophysiology has, in contrast, been largely overlooked and forgotten. Hartley's vibration theory is examined. On the one hand it is shown how closely it is related to Sir Isaac Newton's mathematical physics and on the other how well it complements the association theory. The vibration theory, indeed, strongly influenced Hartley's associationist psychology and hence is of more than merely antiquarian interest. Although Hartley's understanding of the central nervous system has long been superseded, his general ideas prefigure some aspects of contemporary neurophysiology and philosophy of mind and thus provide a further reason for rescuing his vibrationism from oblivion.

  17. Evaluation of MARC for the analysis of rotating composite blades

    NASA Technical Reports Server (NTRS)

    Bartos, Karen F.; Ernst, Michael A.

    1993-01-01

    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.

    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.

  1. Grape marc extract acts as elicitor of plant defence responses.

    Goupil, Pascale; Benouaret, Razik; Charrier, Olivia; Ter Halle, Alexandra; Richard, Claire; Eyheraguibel, Boris; Thiery, Denis; Ledoigt, Gérard

    2012-07-01

    Plant protection based on novel alternative strategies is a major concern in agriculture to sustain pest management. The marc extract of red grape cultivars reveals plant defence inducer properties. Treatment with grape marc extract efficiently induced hypersensitive reaction-like lesions with cell death evidenced by Evans Blue staining of tobacco leaves. Examination of the infiltration zone and the surrounding areas under UV light revealed the accumulation of autofluorescent compounds. Both leaf infiltration and a foliar spray of the red grape extract on tobacco leaves induced defence gene expression. The PR1 and PR2 target genes were upregulated locally and systemically in tobacco plants following grape marc extract treatment. The grape extract elicited an array of plant defence responses making this natural compound a potential phytosanitary product with a challenging issue and a rather attractive option for sustainable agriculture and environmentally friendly practices.

  2. Memories of David Kirzhnits

    Bolotovsky, B. M.

    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."...

    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

    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.

    In the present study, the process of separation and purification of isohamnetin from marc of sea buckthorn was obtained. The antioxidant properties of the pure isolated isorhamnetin were evaluated by the scavenging of the diphenylpicrylhydrazyl radical (DPPH), iron (III) to iron (II)-reducing, and iron-chelating assays. High purity isorhamnetin (92.1%) was obtained and the results of antioxidant assays showed that isorhamnetin performed significantly compared with ascorbic acid and BHT, and the linear correlations were good in these assays. In conclusion, isorhamnetin may have potential as a natural antioxidant to alternate synthetic substances as food additive with its antioxidant activity.

    The winery industry generates vast amounts of organic waste during the various stages of wine production. Among the possible methodological alternatives available for its treatment, vermicomposting is one of the best-known processes for the biological stabilization of solid organic wastes by transforming them into safer and more stabilized materials suitable for application to soil. In this study we carried out a mesocosm experiment to evaluate the effectiveness of the active phase of vermicomposting for the stabilization of grape marc, an enriched lignocellulosic by-product obtained after the grape crushing and pressing stages in wine production. For this we analysed the chemical, biochemical and microbiological properties of the product resulting from this phase, in comparison with those in a control treatment. Earthworm activity reduced the abundance of both bacterial and fungal PLFA biomarkers. Decreases in microbial activity and in protease and cellulase activities were also attributed to the presence of earthworms. The differences in microbial communities were accompanied by a reduction in the labile C pool and the cellulose content. These results indicate that earthworms played a key role in the stabilization of the grape marc in the short-term, via its effects on organic matter decomposition and microbial biomass and activity.

    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.

    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.

    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. Copyright © 2012 Elsevier Inc. All rights reserved.

    Here is the history of French physician and otologist, Jean Marc Gaspard Itard (1774-1838). As physician for the Institute for Deaf Mutes in Paris, Dr. Itard became responsible for the care and civilization of the "wild boy of Aveyron," also known as, "The Wild Child" of the Truffaut movie. Their encounter became the first carefully recorded effort to train a culturally deprived individual on a one-to-one basis, or perhaps on any basis. Dr. Itard's work lead directly through Dr. Sequin and Dr. Montessori to us today. If we now stand on the threshold of restoring hearing by implantation to the totally deaf, then the results we expect and the training programs we must follow will naturally take us back to the work of this physician of the French Revolution.

    This (1)H NMR based study profiles metabolites in Greek grape marc distillates, tsipouro and tsikoudia. Eightysix samples of indigenous and international varieties, stemming from major vine growing regions of Greece were investigated. The monitoring protocol addressed the global metabolic profile of untreated samples and accomplished the unambiguous assignment of 35 metabolites. NMR spectra were acquired by applying the robust, sensitive and rapid WET1D NMR pulse sequence, which succeeded to unveil the presence of minor compounds in a high ethanol matrix. PCA classified the samples according to their provenance, incorporating also information related to the variety, vintage year and production process within each formed regional assembly. Metabolites such as fusel alcohols, polyols, ethyl esters, mono- and di-saccharides were associated with the classification of samples. OPLS-DA ascribed to samples of common regional entity characteristic genotypic metabolites and probed to the potential influence of the vintage effect. Finally, metabolite profiling underlined the influence of the fermentation and distillation procedures.

    Following a description about the characteristics of akinetic mutism (AM) and how it differs from locked-in syndrome (LIS) and a disorder of consciousness (DOC), we present the case of David, a 71-year-old man with AM. David sustained a stroke following a middle cerebral artery (MCA) thrombus. A CT scan at the time detected old ischaemic infarcts affecting the right frontal lobe, the left occipital lobe and the left parietal lobe so David had bilateral brain damage. Initially thought to have a DOC, further neuropsychological assessments administered when David had improved a little, resulted in the diagnosis of AM. Although David spoke little, when he did speak, his words and phrases were well articulated, grammatical and with appropriate intonation. He was alert and visually aware and he was not paralysed. We discuss whether the diagnosis was correct and address the difficulties in assessing such patients.

    Under high dose treatment with sulfamethoxazole (SMX)/trimethoprim (TMP), hypersensitivity reactions occur with a high incidence. The mechanism of this adverse drug reaction is not fully understood. Several steps in the toxification pathway of SMX were investigated. The aim of our study was to investigate the reduction of sulfamethoxazole hydroxylamine (SMX-HA) in this toxification pathway, which can possibly be catalyzed by the mARC-containing N-reductive enzyme system. Western blot analyses of subcellular fractions of porcine tissue were performed with antibodies against mARC-1, mARC-2, cytochrome b5 type B, and NADH cytochrome b5 reductase. Incubations of porcine and human subcellular tissue fractions and of the heterologously expressed human components of the N-reductive enzyme system were carried out with SMX-HA. mARC-1 and mARC-2 knockdown was performed in HEK-293 cells. Kinetic parameters of the heterologously expressed human protein variants V96L, A165T, M187 K, C246S, D247H, and M268I of mARC-1 and G244S and C245W of mARC-2 and N-reductive activity of 2SF, D14G, K16E, and T22A of cytochrome b5 type B were analyzed. Western blot analyses were consistent with the hypothesis that the mARC-containing N-reductive enzyme system might be involved in the reduction of SMX-HA. In agreement with these results, highest reduction rates were found in mitochondrial subcellular fractions of porcine tissue and in the outer membrane vesicle (OMV) of human liver tissue. Knockdown studies in HEK-293 cells demonstrated that mARC-1 and mARC-2 were capable of reducing SMX-HA in cell metabolism. Investigations with the heterologously expressed human mARC-2 protein showed a higher catalytic efficiency toward SMX-HA than mARC-1, but none of the investigated human protein variants showed statistically significant differences of its N-reductive activity and was therefore likely to participate in the pathogenesis of hypersensitivity reaction under treatment with SMX.

    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

    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.

    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.

  2. Minerals and organic nitrogen present in grape marc hydrolyzates enhance xylose consumption by Lactobacillus pentosus.

    PubMed

    Rivera, Oscar Manuel Portilla; Torrado, Ana María; Moldes, Ana Belén; Domínguez, José Manuel

    2009-02-01

    This work deals with the nutritional evaluation of grape marc hydrolyzates as fermentation medium for Lactobacillus pentosus. Usually, the fermentation of xylose and arabinose in the presence of glucose remains a primary obstacle for economical biomass conversion. The few microorganisms that can grow simultaneously on both pentose and hexose sugars contained in lignocellulosic feedstocks typically grow slowly and demonstrate marginal yields and productivities. Moreover, lignocellulosic hydrolyzates contain phenolic compounds and other components originated by the degradation of sugars that can inhibit lactic acid fermentation. However, in this case, grape marc hydrolyzates not only did not need a detoxification stage, but it also improved the xylose consumption by Lactobacillus pentosus with a faster and more efficient conversion of hemicellulosic sugars compared with synthetic media. After analysis of grape marc hydrolyzates, it was observed that minerals such as K (2,707 mg/L), Ca (3,681 mg/L), and Mg (198.5 mg/L) are present in higher concentration than those found in the general medium of Lactobacillus (1,705 mg/L of K, 58.3 mg/L of Ca, and 27.0 mg/L of Mg). Moreover, grape marc hydrolyzates contain an additional source of nitrogen (9.2 g/L) which, together with their elevated mineral concentration, improved lactic acid fermentation compared with synthetic media.

  17. David Gill: clock maker to global astronomer

    NASA Astrophysics Data System (ADS)

    2014-04-01

    Reduction in the uncertainty of physical measurements underpinned many advances in solar and stellar parallax, the determination of longitude, geodesy, and the accurate mapping of the heavens using celestial photography in the late nineteenth century. A pioneer in these areas, who successfully made the transition from clock maker in Aberdeen to H.M. Astronomer at the Cape of Good Hope was David Gill (1843-1914); Sir David Gill, K.C.B. from 1900. This paper celebrates the first third of Gill's career in astronomy and geodesy up to the time he was made redundant from Dun Echt Observatory at the end of 1875. It highlights how his horological skills were applied to telescope design and also how his aspirations to become a global astronomer started. The paper is timed to coincide with Gill's centenary anniversary year - he died 24 January 1914.

  19. A novel implementation of mARC treatment for non-dedicated planning systems using converted IMRT plans.

    2013-08-03

    The modulated arc (mARC) technique has recently been introduced by Siemens as an analogue to VMAT treatment. However, up to now only one certified treatment planning system supports mARC planning. We therefore present a conversion algorithm capable of converting IMRT plans created by any treatment planning system into mARC plans, with the hope of expanding the availability of mARC to a larger range of clinical users and researchers. As additional advantages, our implementation offers improved functionality for planning hybrid arcs and provides an equivalent step-and-shoot plan for each mARC plan, which can be used as a back-up concept in institutions where only one linac is equipped with mARC. We present a feasibility study to outline a practical implementation of mARC plan conversion using Philips Pinnacle and Prowess Panther. We present examples for three different kinds of prostate and head-and-neck plans, for 6 MV and flattening-filter-free (FFF) 7 MV photon energies, which are dosimetrically verified. It is generally more difficult to create good quality IMRT plans in Pinnacle using a large number of beams and few segments. We present different ways of optimization as examples. By careful choosing the beam and segment arrangement and inversion objectives, we achieve plan qualities similar to our usual IMRT plans. The conversion of the plans to mARC format yields functional plans, which can be irradiated without incidences. Absolute dosimetric verification of both the step-and-shoot and mARC plans by point dose measurements showed deviations below 5% local dose, mARC plans deviated from step-and-shoot plans by no more than 1%. The agreement between GafChromic film measurements of planar dose before and after mARC conversion is excellent. The comparison of the 3D dose distribution measured by PTW Octavius 729 2D-Array with the step-and-shoot plans and with the TPS is well above the pass criteria of 90% of the points falling within 5% local dose and 3

  1. mARC prostate treatment planning with Varian Eclipse for flat vs. FFF beams.

    PubMed

    Bell, Katharina; Dzierma, Yvonne; Palm, Jan; Nuesken, Frank; Licht, Norbert; Rübe, Christian

    2016-03-01

    The modulated arc (mARC) technique as an alternative to VMAT is a rotational IMRT irradiation with burst mode delivery. Varian has recently implemented an option for mARC-planning into the Eclipse treatment planning system (TPS) and so far mARC-planning with this TPS has not been evaluated systematically. Therefore, for prostate treatment with Eclipse we compare mARC with IMRT using flat (6MV) and flattening-filter-free (FFF, 7MV) beam energies. For ten prostate cancer patients standardized re-contouring and re-planning was performed with a prescription of 76Gy to the complete planning-target-volume (PTV). IMRT and mARC plans (6MV vs. FFF 7MV) were compared pairwise considering indices for plan quality. All plans were delivered on an anthromorphic phantom equipped with thermoluminescent dosimeters to measure out-of-field dose and treatment times. Regarding PTV coverage, there was no marked preference for either technique or energy. The evaluation of organs at risk showed improved bladder sparing of the mARC plans up to about 75Gy; above this dose the IMRT plans achieved significant better sparing. The use of the FFF-beam-energy and mARC-technique resulted in a significant decrease in out-of-field dose. This combination also led to a drastic reduction of treatment time by factor of three in comparison with 6MV IMRT. While highly conformal treatment plans could be created by the use of all modalities, the combination of the high dose rate with mARC appears to be the preferable option as it benefits from a marked decrease in treatment time and out-of-field dose.

  4. Morphometric variability within the axial zone of the southern Juan de Fuca Ridge: Interpretation from Sea MARC II, Sea MARC I, and deep-sea photography

    USGS Publications Warehouse

    Kappel, Ellen S.; Normark, William R.

    1987-01-01

    The morphometric characteristics of the axial regions of oceanic spreading centers are determined by (1) the type of volcanic flows, (2) the relation between primary volcanic relief (on a scale of a few meters to tens of meters) and degree of sediment cover, and (3) the extent of surficial expression and timing of tectonic disruption of the young oceanic crust. Even within a single, continuous, linear spreading-ridge segment with relatively uniform axial valley dimensions over a distance of 50 or more kilometers, such as along the southern Juan de Fuca Ridge, the changes in morphometric characteristics along axis within the youngest crust indicate distinct variation in tectonic and volcanic activity over short distances within short time periods. An integrated analysis of Sea MARC I, Sea MARC II, and photographic data for the southernmost continuous segment of the Juan de Fuca Ridge shows that generalizations about tectonic and volcanic processes at spreading ridges must consider both the temporal scale of processes as well as the physical scales of observations if predictive models are to be successful. Comparison of the morphometric expression within the major hydrothermal vent area and the rest of the southernmost ridge segment suggests that the mapped distribution of hydrothermal vents may reflect the extent of survey effort rather than uniqueness of geologic setting.

    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.

    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. © The Author(s) 2014.

    Infection of porcine reproductive and respiratory syndrome virus (PRRSV) induces cell apoptosis both in vivo and in vitro. However, the correlation between host cell apoptosis and PRRSV replication is unclear. Here, the promotion of PRRSV propagation by cell apoptosis in MARC-145 cells was reported. The observation on propagation of field highly pathogenic PRRSV (HP-PRRSV) in MARC-145 cells showed that infection of overgrown MARC-145 cells obviously elevated virus production and cell apoptosis was triggered in these cells before virus inoculation. The investigation on propagation of field HP-PRRSV in apoptosis induced MARC-145 cells displayed that induction of apoptosis further increased the virus production and a vigorous viral RNA replication accompanied by fast virus release in these cells was detected in the initial 24h post infection. In addition, when field HP-PRRSV was serially passed in drug-treated MARC-145 cells, the progeny viruses kept a stable viral titer and infectivity to its native target cells in the tested generations. In summary, these findings demonstrated that apoptotic MARC-145 cells were more susceptible to field HP-PRRSV and propagation of the virus was promoted by effective replication and cell-to-cell transmission of the virus in these cells.

    We present a new grid of model photospheres for the SDSS-III/APOGEE survey of stellar populations of the Galaxy, calculated using the ATLAS9 and MARCS codes. New opacity distribution functions were generated to calculate ATLAS9 model photospheres. MARCS models were calculated based on opacity sampling techniques. The metallicity ([M/H]) spans from -5 to 1.5 for ATLAS and -2.5 to 0.5 for MARCS models. There are three main differences with respect to previous ATLAS9 model grids: a new corrected H{sub 2}O line list, a wide range of carbon ([C/M]) and {alpha} element [{alpha}/M] variations, and solar reference abundances from Asplund et al. The added range of varying carbon and {alpha}-element abundances also extends the previously calculated MARCS model grids. Altogether, 1980 chemical compositions were used for the ATLAS9 grid and 175 for the MARCS grid. Over 808,000 ATLAS9 models were computed spanning temperatures from 3500 K to 30,000 K and log g from 0 to 5, where larger temperatures only have high gravities. The MARCS models span from 3500 K to 5500 K, and log g from 0 to 5. All model atmospheres are publicly available online.

    Nowadays grape marc represents one of the main by-product of winemaking. Many South Europe countries valorize this ligno-cellulosic waste through fermentation and distillation for industrial alcoholic beverage production. The storage of marcs is a crucial phase in the distillation process, due to the physicochemical transformations ascribed to microbial activity. Among the methods adopted by distillers to improve the quality of spirits, the use of selected yeasts has not been explored so far, therefore in this work we evaluated the selection criteria of Saccharomyces cerevisiae strains for grape marc fermentation. The proposed selection procedure included three steps: characterization of phenotypical traits, evaluation of selected strains on pasteurised grape marc at lab-scale (100 g) and pilot-scale fermentation (350 kg). This selection process was applied on 104 strains isolated from grape marcs of different origins and technological treatment. Among physiological traits, β-glucosidase activity level as quality trait seems to be only partially involved in increasing varietal flavour. More effective in describing yeast impact on distillate quality is the ratio higher alcohols/esters that indicates strain ability to increase positive flavours. Finally, evaluating grape marc as source of selected yeasts, industrial treatment rather than varietal origin seems to shape strain technological and quality traits. Copyright © 2014 Elsevier Ltd.

    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.

    The Iwokrama International Centre for Rain Forest Conservation in Guyana is headed by Australian forester David Cassells who is also chairman of the Advisory Group for the World Conservation Union Forest Conservation Program. He states that this program is different from other projects to conserve tropical forests since it focuses on financial sustainability and self-sufficiency. He also plans that the revenue for the center will come from a mixture of eco-forestry with certified logging, ecotourism, sustainable production of non-timber products such as vines and latexes, bioprospecting, and the sale of forest management expertise. He further added that the program's success could change the way people value and use tropical forests.

    David Lukens Reasoner, former head of NASA's Ionospheric Physics branch, died on April 21, 1992. Reasoner was born July 1, 1941. He worked tirelessly to expand NASA's Space Physics Division, bringing his deep experience and personal expertise to bear on the challenges of growth.During the magical period of the late 1950s and early 1960s when America turned its eyes toward space and the Moon, David Lukens Reasoner journeyed north from the nearby Texas town of Dickinson to Rice University with an idea of getting involved in exploring the frontiers of space. He pursued a course of study in electrical engineering and received a bachelor's degree in 1963 and a master's degree in 1964. In the early 1960s, the Space Science Department at Rice was formed, and President John Kennedy visited to say that America chose to go to space not because it is easy but because it is hard and because it would require the very best talents of our nation to succeed. Dave Reasoner was one of those talented people. His excellence in electrical engineering and physics, combined with his natural abilities in the laboratory, suited him ideally for building the machines of space. As a student, he built sounding rocket payloads and multiple instruments for satellites and experiment packages that were placed on the Moon by the Apollo astronauts. He completed his doctoral degree in space science in 1968. It was in these early thrilling days of space exploration that I first met Dave, beginning a friendship and collegial relationship that was to last 27 years.

    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

    When David Korn, MD, was named dean of the Stanford University School of Medicine on October 9, 1984, he assumed leadership of a world class research institution. Stanford was at the forefront of medicine in the areas of transplantation and oncology, and the steady influx of privately insured patients had generated a net operating surplus of $17 million in that year alone. However, in the same issue of the Stanford University Hospital newsletter which announced the selection of Korn as Dean, a small article appeared on a new prospective payment system based on diagnosis-related groups (DRGs). The article stated that the new system had begun smoothly, though some payments for cost outliers had been delayed. Other cost containment measures soon followed, most notably the implementation of managed care, and by 1990, Stanford was $14 million in the red. Buffeted by changes in medical reimbursement, competition with less costly hospitals, and a nasty squabble with Congress over indirect research costs, Stanford has been on the frontlines of a struggle now confronting many academic medical centers. After successfully consolidating the university's clinical services into a unified Stanford Health System, Korn announced that he would be stepping down as Dean on April 1. Interviewed in his office in Palo Alto, Korn reflected on the difficulties of dealing with managed care, the current financial state of the institution, and what Stanford's experience may predict for other academic medical centers.

    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.

  12. David MacKay's wooden blocks

    2017-06-01

    This paper is dedicated to the memory of Professor Sir David MacKay FRS. In his inspiring last talk, MacKay discussed the problem of packing his young son's identical wooden blocks, of size 2×1×1. How many ways are there of packing n3/2 such blocks into a cubical box of volume n3? This is the same problem as finding the entropy of cubic packing of dimeric molecules, so the investigation is not merely childish. Here, I use this example as an exemplar of the use of nested sampling in computational inference. In this analogy, the posterior covers the "glassy" arrangements of non-overlapping blocks in the box, whereas the prior represents the wider set of unrestricted model configurations. The required number of possible glass states is the compressive prior-to-posterior fraction of the known number of model configurations. And the compression (as logarithm) is immediately available from the number of equilibrating iterations in nested sampling. The clarity of this example offers useful lessons for computational inference more generally.

    Background The recently implemented mARC-rotation-technique is capable to deliver high dose rate bursts. For the case of hypopharynx cancer plans we evaluate whether the mARC can achieve an advantage in treatment time in comparison to IMRT. These plans consider two arcs with flat and flattening filter free (FFF) beam energies. Materials and Methods For 8 hypopharynx-cancer patients step-and-shoot-IMRT and mARC plans were created retrospectively using flat and FFF beam energy. The comparison of the plan scenarios considered measures of quality for PTV coverage and sparing of organs at risk. All plans were irradiated on an anthromorphic phantom equipped with thermoluminescent dosimeters to measure scattered dose and treatment times. Results A visual comparison of the dose distribution did not show a marked preference for either technique or energy. The statistical evaluation yielded significant differences in favor of the mARC technique and the FFF energy. Scattered dose could be decreased markedly by the use of the mARC technique. Treatment times could be reduced up to 3 minutes with the use of mARC in comparison to IMRT. The high dose rate energy results in another time advantage of about 1 minute. Conclusions All four plan scenarios yielded equally good quality plans. A combination of the mARC technique with FFF 7 MV high dose rate resulted in a decrease of treatment times from about 9 minutes to 5–6 minutes in comparison to 6 MV IMRT. PMID:27741272

    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.

    Five grape marc composts prepared by different procedures (composting and vermicompost at several scales) were tested as potential components of plant growth media. The five composts had high organic matter content (>90%), low electric conductivity (<1 dS m(-1)) and a pH between 7 and 8. Different chemical and biochemical analyses performed indicated the higher stability of those composts submitted to a longer composting process or to a vermicomposting process (lower water soluble organic matter, respiration and dehydrogenase activity). In order to determine the suitability of the composts as substrate components, plant growth tests were performed by blending the composts with peat or commercial substrate at two compost rates (25% and 50%). The mixtures were sown with barley (Hordeum vulgare L.) and grown under controlled conditions in an incubation chamber. No prejudicial effects derived from the use of composted grape marc were observed, whatever the procedure of composting used. The results showed that four out of the five composts would be suitable for use in plant growth substrates elaboration, as they did not reduce productivity with respect to the control substrates.

Compared with the control, these two agents extended the sustaining time of high temperature from 4 days to 11 and 12 days, promoted the decrease of C/N ratio, and the NO(3)- -N concentration increased by 58.0% and 64.2%, respectively. After the amendment of MF or MR, the total N, P and K contents, total porosity and water-holding porosity in the compost increased significantly, while the bulk density decreased. No significant difference was observed in the effects of MR and MF on the high temperature composting process of passionflower fruit marc, but MF was more beneficial to the improvement of compost quality.

    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

    The FIFA Medical and Research Centre (F-MARC) has designed a comprehensive warm-up program targeting muscular strength, body kinaesthetic awareness, and neuromuscular control during static and dynamic movements to decrease injury risk for soccer players. Prior studies have investigated the effectiveness of the F-MARC programs, but have not consistently reported a statistically significant reduction in injury and reduction in time loss due to injury from utilizing the program. The purpose of this study was to conduct a systematic review and meta-analysis of randomized controlled trials and interventional studies that evaluated the efficacy of the F-MARC injury prevention programs in soccer. Two independent researchers searched the relevant article databases. The keyword domains used during the search were 'F-MARC', 'FIFA 11+', 'the 11+', 'injury prevention programs', 'soccer', and variations of these keywords. The initial search resulted in 4299 articles which were filtered to nine articles that met the inclusion criteria. Main inclusion criteria were randomized controlled trials or interventional studies, use of F-MARC injury prevention programs, and the primary outcome measuring overall and lower extremity injuries. Extracted data were entered and analyzed using Comprehensive Meta-Analysis software, version 2 (CMA.V2). The pooled results based on total injuries per 1000 h of exposure showed that F-MARC injury prevention programs had a statistically significant reduction in the overall injury risk ratio of 0.771 (95% CI 0.647-0.918, p = 0.003) and the lower extremity injury risk ratio of 0.762 (95% CI 0.621-0.935, p = 0.009). Moreover, FIFA '11+' had a statistically significant reduction in the overall injury risk ratio to 0.654 (95% CI 0.537-0.798, p < 0.001) and the lower extremity injury risk ratio of 0.612 (95% CI 0.475-0.788, p < 0.001). However, FIFA '11' did not reach significance for the lower extremity and overall injury reduction. It can be suggested that

  4. Acidification of grape marc for alcoholic beverage production: effects on indigenous microflora and aroma profile after distillation.

    Grappa is an Italian alcoholic beverage obtained from distillation of grape marc, the raw material derived from separation of must during the winemaking process. Marc is stored for a period lasting from few days to several weeks, when fermentation of residual sugars occurs mainly by yeast activity. Many distilleries have adopted different solutions to manage this critical phase in order to avoid spoilage microorganisms: marc acidification is the most widely diffused. In this work, Prosecco grape pomace was acidified with sulphuric acid (to pH 2.9) and stored, whereas non-acidified grape marc was used as control (pH 3.9). Samples for microbiological analysis were collected at the beginning of the storage period, after 15 and 43days. At the beginning of the ensilage (time T0) the indigenous microflora was represented both by yeasts and bacteria at a concentration of about 10(6)cfu/g. During the first 15days, when the fermentation generally takes place, yeast population grew considerably (up to 10(7)cfu/g) in acidified grape marc, where bacterial population was maintained at low levels. Moreover, yeast populations recovered at the three sampling times in both treated and untreated marc were genetically characterised. This analysis showed that the species succession lead to non-Saccharomyces species dominance (in particular Issatchenkia and Pichia genera) in both conditions although acidified marc showed a lower percentage of Saccharomyces at any sampling time analysed, this meaning that non-Saccharomyces species were favoured in this environment. Gas chromatographic analysis showed a remarkable change in the aromatic profile of distilled grape marcs at the end of the storage, thus evidencing that concentration of monitored volatile compounds usually produced by microflora was generally lowered by the acidification treatment. This work demonstrates for the first time the strong effect of a persistent acidification treatment both on the microbiota of grape pomace and on

    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.

    2017-02-01

    The aim of this study is the evaluation of the parameters for the material model description in simulation of plasticity and fracture in shearing processes. The experimental measurements and the simulations are performed at room temperature for TWIP steel and 38MnVS6. The behaviour of materials is described using MARC/MENTAT and DEFORM software based on the finite element method. The material model is made up on the basis of tension test. The fracture criteria are based on the experimental failure during tension and torsion tests. The fracture models Normalized Cockcroft-Latham (NCL) and Oyane are used for subsequent simulation of shearing. The description of shearing comprises not only the initiation of a fracture but also the growth of the fracture until the material parts are separated. This issue is solved by means of two numerical methods, the softening and the element deletion.

  8. Effect of experimental parameters in the pressurized solvent extraction of polyphenolic compounds from white grape marc.

    2014-08-15

    A method based on pressurized solvent extraction (PSE) to determine main polyphenolic compounds in the grape marc obtained as a byproduct of the white winemaking process has been developed. As response variables in the optimisation process include main individual polyphenols, as well as spectrophotometric indexes. The optimised PSE procedure implies the use of 1 g of sample, without preliminary clean-up step, sea sand as dispersant, temperature of 105 °C, methanol (63%) in water as solvent, and 5 min of extraction time (2 static cycles). The performance of the proposed method has been assessed in terms of recovery (91-105%), linearity (R(2)>0.995) and precision. The applicability of the method was demonstrated by the analysis of bagasse samples collected from 12 wineries located in Galicia (NW Spain). Data of the in vitro antioxidant activities of the PSE extracts are also discussed. Copyright © 2014 Elsevier Ltd. All rights reserved.

  9. Obituary: David Q. Wark, 1918-2002

    NASA Astrophysics Data System (ADS)

    McMillin, Larry Max

    2003-12-01

    David Q. Wark, a research meteorologist at the National Environmental Satellite, Data, and Information Service of the National Oceanic and Atmospheric Administration (NOAA/NESDIS) and its predecessor organizations for 55 years, died of cancer 30 July 2002. 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. This work was described in the landmark 1965 Wark and Fleming paper in the American Meteorological Society's Monthly Weather Review. From that early period until just weeks before his death, Dr. Wark continued

  10. Improved retention of imidacloprid (Confidor) in soils by adding vermicompost from spent grape marc.

    2007-05-25

    Batch sorption experiments of the insecticide imidacloprid by ten widely different Spanish soils were carried out. The sorption was studied for the active ingredient and its registered formulation Confidor. The temperature effect was studied at 15 degrees C and 25 degrees C. The addition of a vermicompost from spent grape marc (natural and ground), containing 344 g kg(-1) organic carbon, on the sorption of imidacloprid by two selected soils, a sandy loam and a silty clay loam, having organic carbon content of 3.6 g kg(-1) and 9.3 g kg(-1), respectively, was evaluated. Prior to the addition of this vermicompost, desorption isotherms with both selected soils, were also performed. The apparent hysteresis index (AHI) parameter was used to quantify sorption-desorption hysteresis. Sorption coefficients, K(d) and K(f), for the active ingredient and Confidor(R) in the different soils were similar. Sorption decreased with increasing temperature, this fact has special interest in greenhouse systems. A significant correlation (R(2)=0.965; P<0.01) between K(f) values and the organic carbon (OC) content was found, but some soils showed higher sorption coefficients than that expected from their OC values. The normalized sorption coefficients with the soil organic carbon content (K(oc)) were dispersed and low, implying that other characteristics of soils could contribute to the retention capacity as well. The spent grape marc vermicompost was an effective sorbent of this insecticide (K(f)=149). The sorption of imidacloprid increased significantly in soils amended with this vermicompost. The most pronounced effect was found in the sandy loam soil with low OC content, where the addition of 5% and 10% of vermicompost increased K(f) values by 8- and 15-fold, respectively. Soil desorption of imidacloprid was slower for the soil with the higher OC and clay content.

    Miller, Sylvia L.

    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

  12. INTRODUCTION: David Sherrington as a mentor of young scientists

    2008-08-01

    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

    This study aimed to determine the effect of supplementation of broiler diets with red ginseng marc and α-tocopherol on the growth performance and meat quality during a 35-day feeding period. A total of 225 Hubbard male broiler chicks were fed diets supplemented with 0%, 1%, 2% and 3% red ginseng marc, or 2% red ginseng marc + 200 IU α-tocopherol kg(-1) and randomly allocated to five dietary groups (15 floor pens), so that each group had three replicates and 15 broilers per pen (0.09 m(2) per bird). There were no differences among the treated groups with regard to growth performance and proximate composition, except for mortality and crude fat in broilers. Serum cholesterol levels were lower in the chickens receiving diets supplemented with red ginseng marc and α-tocopherol than those in the control. With the exception of water-holding capacity or shear force values, increasing levels of red ginseng marc and a combination of red ginseng marc and α-tocopherol affected chicken thigh meat quality by decreasing the pH and thiobarbituric acid reactive substance and increasing the total phenol and DPPH-radical scavenging compared with those in the control. Broiler diets with increasing levels of red ginseng marc and the combination of red ginseng marc and α-tocopherol did not affect the color of thigh muscle, but the treatment significantly increased a* values. Supplementation of poultry diets with 3% red ginseng marc markedly reduced mortality and serum cholesterol levels and remarkably improved meat quality in broilers. © 2013 Society of Chemical Industry.

  15. Mental disorder that afflicted King David the Great.

    PubMed

    Ben-Noun, Liubov

    2004-12-01

    This research uses the tools of modern medical science to study ancient descriptions of the symptoms suffered by King David. Biblical texts were examined, with a close study of verses relating to the mental disorder that afflicted King David, the second and greatest King of Israel, who ruled more than 3525 years ago. We include no commentaries, but refer only to the words of the Bible exactly as written. Evaluation of the passages referring to King David indicated that he was afflicted by some mental disorder, and among the many possibilities major depression, dysthymia and minor depression are the most likely. Of these diagnoses, major depression seems the most acceptable. This report suggests that the roots of contemporary psychiatry can be traced back to Biblical times.

  10. Chella David: a lifetime contribution in translational immunology.

    PubMed

    Gershwin, M Eric; Shoenfeld, Yehuda

    2011-09-01

    Immunology, like most scientific disciplines, is filled with buzz words. One such buzz word or term has been coined "translational immunology". Indeed, translational research is amongst the most popular expressions used to justify the use of basic research in the hopes that such research will lead to solutions to clinical problems. In fact, no such justification is needed and some of the most important observations in clinical medicine have been derived from basic science; basic science that had no idea at its time of its usefulness in clinical medicine. This special issue is devoted to Chella David. Chella's contributions in immunology have been legion. Before inbred mice became popular, long before multi-million dollar companies were developed to develop such models, Chella David was hard at the bench studying the genetics of the murine immune system and the importance of such mouse models in autoimmune diseases. Importantly, Dr. David provided animals without strings, without the burdens of MTAs, that now impede research. Chella has been generous with his time, with his reagents, and has been a caring and devoted mentor to generations of students. This issue is part of our series to recognize autoimmunologists and dedicated themes that include papers in multiple disciplines of immunology, but especially are focused on cutting-edge applications that will improve clinical therapeutics. Chella David, at age 75, is an athlete in immunology and still keeps going with the same enthusiasm as manifest as a young post-doc. Copyright © 2011 Elsevier Ltd. All rights reserved.

  17. Kinetic modeling of ultrasound-assisted extraction of phenolic compounds from grape marc: influence of acoustic energy density and temperature.

    PubMed

    Tao, Yang; Zhang, Zhihang; Sun, Da-Wen

    2014-07-01

    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.

    Viral infections usually result in alterations in the host cell proteome, which determine the fate of infected cells and the progress of pathogenesis. To uncover cellular protein responses in porcine reproductive and respiratory syndrome virus (PRRSV), infected pulmonary alveolar macrophages (PAMs) and Marc-145 cells were subjected to proteomic analysis involving two-dimensional electrophoresis (2-DE) followed by MALDI-TOF-MS/MS identification. Altered expression of 44 protein spots in infected cells was identified in 2D gels, of which the 29 characterised by MALDI-TOF-MS/MS included 17 up-regulated and 12 down-regulated proteins. Some of these proteins were further confirmed at the mRNA level using real-time RT-PCR. Moreover, Western blot analysis confirmed the up-regulation of HSP27, vimentin and the down-regulation of galectin-1. Our study is the first attempt to analyze the cellular protein profile of PRRSV-infected Marc-145 cells using proteomics to provide valuable information about the effects of PRRSV-induced alterations on Marc-145 cell function. Further study of the affected proteins may facilitate our understanding of the mechanisms of PRRSV infection and pathogenesis.

    Grape marc contains a number of compounds with potential antimethanogenic activity in ruminants, including condensed tannins (CTs). Using direct phloroglucinolysis, a survey of CT chemistry across 66 grape marc samples showed diversity in concentration (6.9 to 138.8 g/kg of dry matter). Concentration was found to be independent of CT composition, although all compositional variables were significantly correlated (P < 0.0001). Twenty samples diverse in CT were selected from a cluster analysis and analyzed for compounds relevant to ruminant digestion and methanogenesis, including metabolizable energy (6.6-12.0 MJ/kg DM), crude protein (3.2-14.4% DM), neutral detergent fiber (18.4-61.4% DM), and ethanol soluble carbohydrates (2.0-40.6% DM). Fatty acid concentrations varied throughout the 20 samples (5.2-184.5 g/kg DM), although fatty acid profile showed two distinct groups. Grape marc varies widely in nutritional value, and in compounds that have been linked with changes in ruminant digestion and methane emissions.

    Satsuma mandarins (Citrus unshiu Marc.) are the predominant cultivated citrus variety in Japan. Clarification of its origin would prove valuable for citrus taxonomy and mandarin breeding programs; however, current information is limited. We applied genome-wide genotyping using a 384 citrus single nucleotide polymorphism (SNP) array and MARCO computer software to investigate the satsuma mandarin parentage. Genotyping data from 206 validated SNPs were obtained to evaluate 67 citrus varieties and lines. A total of five parent–offspring relationships were newly found by MARCO based on the 206 SNP genotypes, indicating that ‘Kishuu mikan’ type mandarins (Citrus kinokuni hort. ex Tanaka accession ‘Kishuu mikan’ and ‘Nanfengmiju’) and ‘Kunenbo’ type mandarins (Citrus nobilis Lour. var. kunip Tanaka accession ‘Kunenbo’ and ‘Bendiguangju’) are possible parents of the satsuma mandarin. Moreover, cleaved amplified polymorphic sequences analysis showed that the genotypes of four regions in chloroplast DNA of ‘Kishuu mikan’ type mandarins were identical to that of the satsuma mandarin. Considering the historical background, satsuma mandarins may therefore derive from an occasional cross between a ‘Kishuu mikan’ type mandarin seed parent (derivative or synonym of ‘Nanfengmiju’) and a ‘Kunenbo’ type mandarin pollen parent (derivative or synonym of ‘Bendiguangju’).

    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.

    The aim of this study was to investigate the potential of retrieving polyphenolic antioxidants directly from wet pomegranate marcs: the fresh by-products obtained after pomegranate juice processing. These by-products mainly consist of internal membranes (endocarp) and aril residues. Even if they are still edible, they are usually discharged during juice production and, thus, they represent a great challenge in an eco-sustainable industrial context. Green technologies, such as ultrasound assisted extraction (UAE) and microwave assisted extraction (MAE), have been employed to convert these organic residues into recycled products with high added value. UAE and MAE were used both in parallel and in series in order to make a comparison and to ensure exhaustive extractions, respectively. Water, as an environmentally friendly extraction solvent, has been employed. The results were compared with those ones coming from a conventional extraction. The most promising extract, in terms of total polyphenol yield and radical scavenging activity, has been tested both as a potential natural additive and as a functional ingredient after its incorporation in a real food model and in a real cosmetic matrix, respectively. This study represents a proposal to the agro-alimentary sector given the general need of environmental “responsible care”. PMID:27763542

    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.

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

    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.

  6. 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.

    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.

    The mitochondrial amidoxime reducing component (mARC) is a molybdenum-containing enzyme and capable of reducing N-hydroxylated structures such as amidoxime prodrugs. In this study, we tested the involvement of mARC in the reduction of N-oxides (amitriptyline-N-oxide, nicotinamide-N-oxide), oximes ((E)-/(Z)-2,4,6-trimethylacetophenonoxime) and a N-hydroxyamidinohydrazone (guanoxabenz). All groups are reduced by mARC proteins, and the enzymes are therefore involved in the interconversion of N-oxygenated metabolites originating from cytochrome P450s and flavin-containing monooxygenases. In addition, these structures open up further options for serving as prodrugs. Thus, with respect to these reactions, testing of candidates with N-oxygenated structures should not solely be carried out in microsomal enzyme sources but as well in mitochondria. However, differences in the reduction of oximes and N-oxides between the two isoforms, namely mARC1 and mARC2, were detectable; N-oxides are exclusively reduced by mARC1. We therefore assume differences between the so far unknown 3D structures of the two proteins.

    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.

    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).

    This paper summarizes the results of a two-day dynamic monitoring of Michelangelo's David subject to environmental loads (city traffic and pedestrian loading induced by tourists visiting the Accademia Gallery). The monitoring was carried out by a no-contact technique using an interferometric radar, whose effectiveness in measuring the resonant frequencies of structures and historic monuments has proved over the last years through numerous monitoring activities. Owing to the dynamic behavior of the measurement system (radar and tripod), an accelerometer has been installed on the radar head to filter out the movement component of the measuring instrument from the measurement of the David's displacement. Measurements were carried out in the presence and absence of visitors, to assess their influence on the dynamic behavior of the statue. A numerical model of the statue was employed to evaluate the experimental results.

    2008-10-01

    In this work the carbon biodegradation of exhausted grape marc (EGM) combined with other organic wastes using the turned pile composting system was studied. Four different piles were made of EGM in Pile 1, EGM mixed with cow manure and straw (CMS) in Pile 2, EGM mixed with municipal solid waste (MSW) in Pile 3 and EGM mixed with grape stalks (GS) in Pile 4. The results obtained were modelled to determine the main kinetic and stoichiometric parameters. Regarding to the rate constants of the composting processes they were increased from 0.033d(-1), the value obtained when EGM was composted alone, to 0.040 and 0.044d(-1) when MSW and GS were added, respectively as co-substrates. However, the addition of CMS reduced the rate constant. About the biodegradable carbon fractions, it was observed that the co-composting reduced significantly the remanent carbon concentration after composting in all the piles whilst increased the readily biodegradable carbon fractions from 35, the value obtained when EGM was composted alone, to 50 and 60%, respectively when MSW or GS were added. As regards the temperature profiles, only Piles 1 and 4 achieved thermal hygienization values and about the nitrogen losses, the lowest percentage of nitrogen loss took place when GS were added, because of its optimum pH and C/N initial ratio. Thus, though any of these wastes could be used for co-composting with EGM, the use of GS as co-substrate and bulking agent for the co-composting process of EGM was recommended.

    Antidesma thwaitesianum Müll. Arg. or mao is widely used as commercial products of juice and wine in Thailand. As a result, waste products from the mao plant, such as mao seeds (MS) and mao marcs (MM), are plentiful. We aimed to purify and analyze polyphenolic content in both MS and MM and to investigate the radical scavenging activities of these polyphenolics against 1,1-diphenyl-2-picryl-hydrazyl (DPPH) and 2,2'-Azinobis (3-ethylbenzothiazoline 6-sulphonate) (ABTS) radicals and thiobarbituric acid reactive products (TBARP). The results showed MS and MM to be an abundant source of polyphenols (97.32 to 130 mg gallic acid equivalents [GAE]/g) and proanthocyanidins. The radical scavenging activities of MS/MM against DPPH and ABTS radicals (IC(50) of 0.85 to 1.21 microg/mL) were significantly higher (P < 0.05) than that of standard trolox (IC(50) of 5.05 microg/mL). Activity of MS/MM extracts were 3.74 and 3.80 microg/mL trolox eq/g f.w. for the DPPH and ABTS assays, respectively. The oxidation of erythrocyte membranes using 2-thiobarbituric acid demonstrated that the protective effect of MS/MM on lipid peroxidation is as strong as grape seed proanthocyanidin extract. These findings suggest that polyphenolic compounds and proanthocyanidins isolated from these mao extracts had much higher antioxidant activities than those of standard trolox and exhibited similar antioxidant potential to grape seed proanthocyanidin extract. These findings may also increase value of mao waste products and allow development of commercial health products.

  1. First results from a combination side-scan sonar and seafloor mapping system (SeaMARC II)

    SeaMARC II (Sea Mapping and Remote Characterization) is both a conventional side-scan sonar and a bathymetric mapping system. It is a 12kHz, long-range, shallow-towed, high-speed system that produces an ocean floor image up to 10km wide. (By contrast SeaMARC I is a 30kHz deep towed, slow-speed side-scan only system.) Bathymetry is determined by measuring 4000 times each second the magnitude and arrival angle of narrow band acoustic energy returned from each side of ship's track. Off-line processing of this series of vectors produces a seafloor bathymetric map along the track with a width 3.4 times the water depth. A 10 knot tow capability allows more than 4000 square kilometers to be surveyed each day. In practice, the average returns from a relatively flat part of the survey area are used to generate a function relating acoustic arrival angle to measured electrical angle. This procedure corrects for local sound speed structure. With this function, the measurements from returns with adequately large magnitudes are converted to acoustic arrival angle. These angles are corrected for tow body attitude and, with the arrival times (range), are converted to horizontal (X) and vertical (Z) distances from the tow body to the reflector. Side-scan images are a combination of the small scale reflecting properties of the bottom (micro-reflectivity) and the specular reflections from bathymetric slopes (macro-reflectivity). SeaMarc II has the unique ability to acquire synoptic data that will allow the two effects to be separated. This unique combination also allows more accurate and rapid understanding of bottom character than with either output by itself.

    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.

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 which appears to have been active at a time, suggest that coarse-grained deposits on this fan are laterally discontinuous.

    The CE-MARC study assessed the diagnostic performance investigated the use of cardiovascular magnetic resonance (CMR) in patients with suspected coronary artery disease (CAD). The study used a multi-parametric CMR protocol assessing 4 components: i) left ventricular function; ii) myocardial perfusion; iii) viability (late gadolinium enhancement (LGE)) and iv) coronary magnetic resonance angiography (MRA). In this pre-specified CE-MARC sub-study we assessed the diagnostic accuracy of the individual CMR components and their combinations. All patients from the CE-MARC population (n = 752) were included using data from the original blinded-read. The four individual core components of the CMR protocol was determined separately and then in paired and triplet combinations. Results were then compared to the full multi-parametric protocol. CMR and X-ray angiography results were available in 676 patients. The maximum sensitivity for the detection of significant CAD by CMR was achieved when all four components were used (86.5%). Specificity of perfusion (91.8%), function (93.7%) and LGE (95.8%) on its own was significantly better than specificity of the multi-parametric protocol (83.4%) (all P < 0.0001) but with the penalty of decreased sensitivity (86.5% vs. 76.9%, 47.4% and 40.8% respectively). The full multi-parametric protocol was the optimum to rule-out significant CAD (Likelihood Ratio negative (LR-) 0.16) and the LGE component alone was the best to rue-in CAD (LR+ 9.81). Overall diagnostic accuracy was similar with the full multi-parametric protocol (85.9%) compared to paired and triplet combinations. The use of coronary MRA within the full multi-parametric protocol had no additional diagnostic benefit compared to the perfusion/function/LGE combination (overall accuracy 84.6% vs. 84.2% (P = 0.5316); LR- 0.16 vs. 0.21; LR+ 5.21 vs. 5.77). From this pre-specified sub-analysis of the CE-MARC study, the full multi-parametric protocol had the highest sensitivity

    David Kasner, MD (1927–2001), used his extensive dissections of eye bank eyes and experiences in teaching cataract surgery to resident physicians to realize that excision of vitreous when present in the anterior chamber of eyes undergoing cataract surgery was preferable to prior intraoperative procedures. Noting that eyes tolerated his maneuvers, he then performed planned subtotal open-sky vitrectomies; first on a traumatized eye in 1961, then on two eyes of patients with amyloidosis (1966–1967). The success of these operations was noted by others, most particularly Robert Machemer, MD. Kasner’s work directly led to further surgical developments, including closed pars plana vitrectomy.

    Summary Phenolic compounds (benzoic and cinnamic acid derivatives) were determined by high-performance liquid chromatography with multiple wavelength detector (HPLC- -MWD) in grape marc distillates aged in Quercus petraea, Quercus robur and Quercus alba wooden barrels. In addition to colour indices and evaluable polyphenols, all samples were described by sensorial analysis. There were significant differences in the mean concentrations of the majority of phenolic compounds among the samples. Gallic and benzoic acids were the most abundant and samples aged in Q. robur from Galicia (NW of Spain) had the highest concentration of most of the determined phenols. Grape marc distillates aged in Q. robur obtained the highest values of all sensorial attributes, whereas samples aged in Q. petraea and Q. alba obtained similar scores. Principal component analysis accounted for 88.32% of total variance, showing a good separation of aged distillates in terms of phenolic compounds and colour characteristics, according to the species and origin of the oak wood used in the ageing process.

    This study aimed at using grape marc for the growth of lactic acid bacteria and bifidobacteria with the perspective of producing a functional ingredient having antioxidant activity. Lactobacillus plantarum 12A and PU1, Lactobacillus paracasei 14A, and Bifidobacterium breve 15A showed the ability to grow on grape marc (GM) based media. The highest bacterial cell density (>9.0 CFU/g) was found in GM added of 1% of glucose (GMG). Compared to un-inoculated and incubated control fermented GMG showed a decrease of carbohydrates and citric acid together with an increase of lactic acid. The content of several free amino acids and phenol compounds differed between samples. Based on the survival under simulated gastro-intestinal conditions, GMG was a suitable carrier of lactic acid bacteria and bifidobacteria strains. Compared to the control, cell-free supernatant (CFS) of fermented GMG exhibited a marked antioxidant activity in vitro. The increased antioxidant activity was confirmed using Caco-2 cell line after inducing oxidative stress, and determining cell viability and radical scavenging activity through MTT and DCFH-DA assays, respectively. Supporting these founding, the SOD-2 gene expression of Caco-2 cells also showed a lowest pro-oxidant effect induced by the four CFS of GMG fermented by lactic acid bacteria and bifidobacteria.

    S-type stars are late-type giants whose atmospheres are enriched in carbon and s-process elements because of either extrinsic pollution by a binary companion or intrinsic nucleosynthesis and dredge-up on the thermally-pulsing asymptotic giant branch. A grid of MARCS model atmospheres has been computed for S stars, covering the range 2700 ≤ Teff(K) ≤ 4000, 0.50 ≤ C/O ≤ 0.99, 0 ≤ log g ≤ 5, [Fe/H] = 0., -0.5 dex, and [s/Fe] = 0, 1, and 2 dex (where the latter quantity refers to the global overabundance of s-process elements). The MARCS models make use of a new ZrO line list. Synthetic spectra computed from these models are used to derive photometric indices in the Johnson and Geneva systems, as well as TiO and ZrO band strengths. A method is proposed to select the model best matching any given S star, a non-trivial operation since the grid contains more than 3500 models covering a five-dimensional parameter space. The method is based on the comparison between observed and synthetic photometric indices and spectral band strengths, and has been applied on a vast subsample of the Henize sample of S stars. Our results confirm the old claim by Piccirillo (1980, MNRAS, 190, 441) that ZrO bands in warm S stars (Teff>3200 K) are not caused by the C/O ratio being close to unity, as traditionally believed, but rather by some Zr overabundance. The TiO and ZrO band strengths, combined with V-K and J-K photometric indices, are used to select Teff, C/O, [Fe/H] and [s/Fe]. The Geneva U-B1 and B2-V1 indices (or any equivalent) are good at selecting the gravity. The defining spectral features of dwarf S stars are outlined, but none is found among the Henize S stars. More generally, it is found that, at Teff = 3200 K, a change of C/O from 0.5 to 0.99 has a strong impact on V-K (2 mag). Conversely, a range of 2 mag in V-K corresponds to a 200 K shift along the (Teff, V-K) relationship (for a fixed C/O value). Hence, the use of a (Teff, V-K) calibration established for M

    The attitudes of 211 students at a university in Mississippi were investigated both before and after seeing the Public Broadcasting Film Who Is David Duke? The film provided evidence of Duke's current racism, anti-Semitism, and pro-Nazi leanings. In a previous study with university students in Louisiana, the majority did not change their attitudes after watching the film (Eisenman, 1993). However, in the present study, students' attitudes showed change in an anti-Duke direction. The findings are discussed and reasons given for the differences between the two samples, and for the popularity of Duke, a former leader of the Ku Klux Klan.

    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.

    1995-05-19

    Former Ku Klux Klan leader, David Duke, planning a second run for governor of Louisiana, said he would curb the AIDS epidemic by tattooing people who are infected with HIV. His suggestion is to put indelible, glow-in-the-dark tattoos on the genitals of people infected with HIV. According to Duke, it may sound very draconian but it would not demean people. He also believes that tattooing would be legal because courts have a history of supporting the quarantining and institutionalizing of people with infectious diseases, such as tuberculosis. Duke said Cuba has had some success in using quarantines to reduce HIV infection, but he does not think it would work in the United States because it would cost too much. According to Duke, many people who get HIV from irresponsible behavior do not tell their partners that they have AIDS--these people are mad at the world and engage in dangerous behaviors even more.

    In Mediterranean countries the most diffuse practice to obtain the valorization of grape marc, the main by-product from winemaking, is the production of spirits. During this process, marc storage for sugar fermentation represents a crucial step, since side-fermentations leading to off-flavours production can very easily occur. In this study we evaluated the effect of the addition of two yeast strains, inoculated separately at the beginning of the storage period, into marcs from two Italian grape varieties with the aim to control the development of autochthonous microbiota and to improve spirit quality. The presence of the inoculated strains was monitored by means of PCR-based approaches. A commercial Saccharomyces cerevisiae strain, chosen as this species is notably the best ethanol producer, showed excellent ability to dominate the autochthonous microflora and to reduce off-flavours as demonstrated by chemical analysis and sensory evaluation. A Saccharomycodes ludwigii strain, chosen for increasing varietal compounds thus enhancing spirit aroma, showed a level of implantation not sufficient to assure a clear beneficial effect on quality. The implantation level of this strain was affected by S. cerevisiae competition since the highest level was found in grape marc with lower sugar content, where indigenous S. cerevisiae were less persistent.

  10. Digital image processing techniques for enhancement and classification of SeaMARC II side scan sonar imagery

    Reed, Thomas Beckett, IV; Hussong, Donald

    1989-06-01

    The recent growth in the production rate of digital side scan sonar images, coupled with the rapid expansion of systematic seafloor exploration programs, has created a need for fast and quantitative means of processing seafloor imagery. Computer-aided analytical techniques fill this need. A number of numerical techniques used to enhance and classify imagery produced by SeaMARC II, a long-range combination side scan sonar, and bathymetric seafloor mapping system are documented. Three categories of techniques are presented: (1) preprocessing corrections (radiometric and geometric), (2) feature extraction, and (3) image segmentation and classification. An introduction to the concept of "feature vectors" is provided, along with an explanation of the method of evaluation of a texture feature vector based upon gray-level co-occurrence matrices (GLCM). An alternative to the a priori texel (texture element) subdivision of images is presented in the form of region growing and texture analysis (REGATA). This routine provides a texture map of spatial resolution superior to that obtainable with arbitrarily assigned texel boundaries and minimizes the possibility of mixed texture signals due to the combination of two or more textures in an arbitrarily assigned texel. Computer classification of these textural features extracted via the GLCM technique results in transformation of images into maps of image texture. These maps may either be interpreted in terms of the theoretical relationships shown between texture signatures and wavelength or converted to geologic maps by correlation of texture signatures with ground truth data. These techniques are applied to SeaMARC II side scan sonar imagery from a variety of geologic environments, including lithified and nonlithified sedimentary formations, volcanic and sedimentary debris flows, and crystalline basaltic outcrops. Application of the above processing steps provided not only superior images for both subjective and quantitative

    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.

    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.

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

    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.

  19. David Hartley's psychobiological associationism and the legacy of Aristotle.

    The idea that there are certain "laws" of learning (similarity, contrast, contiguity) can be traced to Aristotle. He maintained that external stimuli cause small movements in the vessels to the dominant heart, the vestiges of which can be linked to one another. Aristotle's laws of learning were incorporated into the writings of Hobbes, Locke, and Berkeley, men who said nothing about the physiological correlates of mental associations. This left the door open for David Hartley to combine mental associationism with the Newtonian idea that sensations can cause minute particle vibrations in the nerves. Hartley's amalgam of psychology, philosophy, and neurology was first presented in 1746, as a "trial balloon" at the end a little-known monograph on a treatment for kidney stones. It was repeated three years later in his better-known Observations on Man. In many ways, modern psychobiological connectionism can be traced back to Hartley's Conjectures of 1746, in which Aristotle's original thoughts were modified with then current ideas about functions of the mind and the nervous system.

    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.

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

    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.

    The database for annotation, visualization and integrated discovery (DAVID), which can be freely accessed at http://david.abcc.ncifcrf.gov/, is a web-based online bioinformatics resource that aims to provide tools for the functional interpretation of large lists of genes/proteins. It has been used by researchers from more than 5000 institutes worldwide, with a daily submission rate of ∼1200 gene lists from ∼400 unique researchers, and has been cited by more than 6000 scientific publications. However, the current web interface does not support programmatic access to DAVID, and the uniform resource locator (URL)-based application programming interface (API) has a limit on URL size and is stateless in nature as it uses URL request and response messages to communicate with the server, without keeping any state-related details. DAVID-WS (web service) has been developed to automate user tasks by providing stateful web services to access DAVID programmatically without the need for human interactions. The web service and sample clients (written in Java, Perl, Python and Matlab) are made freely available under the DAVID License at http://david.abcc.ncifcrf.gov/content.jsp?file=WS.html.

    Two comparative studies were undertaken using adult, female red and Père David's deer to examine the ovulatory response of these animals to a superovulation regimen and fertilization rates following inter- and intraspecific laparoscopic insemination. In Expt 1 six Père David's deer and 12 red deer hinds were treated during the breeding season with an intravaginal progesterone-impregnated controlled internal drug release device (CIDR) for 14 days, with 200 iu pregnant mares' serum gonadotrophin (PMSG) administered 72 h before the device was withdrawn and eight injections of ovine FSH given at 12 h intervals starting at the time of PMSG administration. Oestrous behaviour began one day after CIDR device withdrawal (Père David's deer: 24.00 +/- 2.32 h; red deer: 24.60 +/- 2.23 h). The duration of oestrus was greater in Père David's deer than in red deer (17.50 +/- 1.43 h and 8.25 +/- 3.25 h, respectively, P < 0.001). The peak LH surge of Père David's deer was 68.65 +/- 4.74 ng ml-1 occurring 29.00 +/- 2.41 h after removal of the CIDR devices. In comparison, the peak LH surge in red deer was 17.09 +/- 3.64 ng ml-1 (P < 0.001), occurring 24.00 +/- 0.00 h after CIDR device withdrawal. Pre-surge concentrations of LH were also greater (P < 0.001) in Père David's deer (1.37 +/- 0.11 ng ml-1) than in red deer hinds (0.41 +/- 0.02 ng ml-1).(ABSTRACT TRUNCATED AT 250 WORDS)

    Swine beta interferon (swIFN-beta) produced in HEK 293 cells infected with a recombinant, replication-defective human adenovirus 5 (Ad5) encoding the swIFN-beta gene was tested for antiviral activity against Porcine reproductive and respiratory syndrome virus (PRRSV). MARC-145 cells were incubated overnight with dilutions of supernatant fluids from HEK 293 cells infected with Ad5-swIFN-beta or with an Ad5 control virus (Ad5-Blue). Treated cells were infected with PRRSV; MARC-145 cells incubated with Ad5-Blue supernatants developed cytopathic effects (CPE), whereas those incubated with swIFN-beta showed no CPE. To confirm the antiviral activity of swIFN-beta, culture fluids from Ad5-swIFN-beta-infected cells were affinity-purified on a Sepharose-anti-swIFN-beta matrix, and the resulting fractions exhibited antiviral activity upon infection with PRRSV. The antiviral effects were specific, as they were blocked by mAbs against swIFN-beta. Additional cultures of MARC-145 cells treated with swIFN-beta-containing supernatants or affinity-purified swIFN-beta were infected with PRRSV and tested by real-time RT-PCR for viral RNA in culture supernatants at various times post-inoculation. These experiments confirmed the protective effects of swIFN-beta. swIFN-beta was also tested for antiviral activity on porcine alveolar macrophages (PAMs) obtained by bronchoalveolar lavage from PRRSV-negative swine. PAMs were treated with dilutions of swIFN-beta or Ad5-Blue culture fluids, infected with PRRSV and tested for viral RNA by real-time RT-PCR. The viral load data showed a dose-dependent protection in swIFN-beta-treated PAMs, whereas no protection was evident from Ad5-Blue culture fluids. The data demonstrate that swIFN-beta protects both MARC-145 cells and PAMs from PRRSV infection.

  5. Life Cycle of a Large Telescope: the David Dunlap Observatory

    When it went into operation in 1935, the 74-inch reflector at the David Dunlap Observatory was the world's second largest and most sophisticated telescope. Designed specifically for stellar spectroscopy, almost all work performed with it until the early 1950s was limited to that specialty. Most University of Toronto staff were expected to contribute to the observatory's programme. However, as the staff expanded and newer research specialties were introduced, the telescope had to be refitted with new auxiliary equipment, or not be used at all. By the late 1960s, the observatory's night sky began to deteriorate due to light pollution from uncontrolled urban growth. While limited work could be performed into the 1990s, the telescope was no longer considered "large” far more powerful, versatile instruments at much superior sites were by then available. That Toronto astronomers had moved on can be demonstrated from their publication records. The end came in 2008 when the University of Toronto decided that the land's value could be used to support astronomical research in a broader sense. In response, the community, which had ignored the observatory for most of its history, and a few dissident astronomers, strongly defended its survival on a number of grounds. The narrative suggests a number of life-cycle stages: 1) maximum use of the instrument due to superior environmental and technical conditions, plus staff homogeneity; 2) application of new technologies to extend the instrument's capability in the face of diversifying research interests and decaying environmental factors; 3) fading value due to obsolescence and poor environmental factors; 4) death or metamorphosis (such as becoming an educational or historical institution). It appears that these phases apply to a number of historical cases. It is not clear, for the Dunlap Observatory, how the fourth phase will play out.

    Mitochondrial amidoxime reducing components (mARC-1 and mARC-2) represent a novel group of Mo containing enzymes in eukaryotes. These proteins form the catalytic part of a three-component enzyme complex known to be responsible for the reductive activation of several N-hydroxylated prodrugs. No X-ray crystal structures are available for these enzymes as yet. Previous biochemical investigation by B. Wahl et al. (J. Biol. Chem. 285 (2010) 37847–37859) has revealed that two of the Mo coordination positions are occupied by sulfur atoms from a pyranopterindithiolate (molybdopterin, MPT) cofactor. In this work, we have used continuous wave and pulsed electron paramagnetic resonance (EPR) and density functional theoretical (DFT) calculations to determine the nature of remaining ligands in the Mo(V) state of the active site of mARC-2. The experiments with samples in D2O have identified the exchangeable equatorial ligand as a hydroxyl group. The experiments on samples in H217O-enriched buffer have shown the presence of a slowly exchangeable axial oxo ligand. The comparison of the experimental 1H and 17O hyperfine interactions with those calculated using DFT has shown that the remaining non-exchangeable equatorial ligand is, most likely, protein-derived, and that the possibility of an equatorial oxo ligand can be excluded.

    Grape marc extract (GME) acts as an elicitor of plant defense responses. This study analyzed GME-induced plant defense reactions in NahG transgenic tobacco. Leaf infiltration of NahG leaves revealed HR-like reactions with reduced lesions and weak deployment of autofluorescent compounds in the surrounding infiltrated tissues. The β-1,3-glucanase PR2-, endochitinase PR3-, and osmotin PR5-target transcript levels were strongly lowered in NahG leaves, and the mutant failed to accumulate the antimicrobial PR1 transcripts. GME-induced protection against Phytophthora parasitica var. nicotianae (Ppn) was evaluated on tobacco leaves. The antimicrobial properties of GME against Ppn were evidenced using a range of in vitro tests. GME-sprayed wild-type leaves showed reduced infection areas, whereas GME failed to induce a protective effect against Ppn in NahG leaves. The results suggest that GME-induced plant defense reactions in tobacco plants was mediated by salicylic acid (SA) and that GME-induced protection against Ppn could be the combined result of antimicrobial and defense actions.

    In this work, the potential use of a biopolymer based on grape marc entrapped in calcium alginate beads for the removal of pigments from an agro industrial effluent was evaluated. The parameters that affect the pigment adsorption such as pH (3.5-7.0), temperature (10-40°C) and initial pigment concentration (6.9-55.1mg/L) were studied by applying an incomplete factorial design. The dependent variables evaluated consisted of color effluent parameters from CIELAB and Tristimulus system, as well as the concentration of pigments in the wastewater after the adsorption treatment. The most significant independent variables tested were the pigments concentration followed by pH, whereas temperature had a negligible effect on the adsorption process. Moreover, at the optimal operational conditions (pH 3.5 and room temperature) kinetic studies were carried out by applying pseudo-first order, pseudo-second order, Chien-Clayton and intraparticle diffusion models, observing a good agreement between theoretical and experimental results.

    Samples of Satsuma mandarin (Citrus unshiu Marc.) nectar, honey sac content and honey were analyzed by FTIR-ATR spectroscopy and reference methods. The spectral analysis allowed detection of the major chemical constituents in C. unshiu nectar-to-honey transformation pathway thus providing information on the intensity and location of the compositional changes occurring during this process. The preliminary results showed that in average more than one-third of sugar-related nectar-to-honey conversion takes place directly in the honey sac; the average sugar content (w/w) was 17.93% (nectar), 47.03% (honey sac) and 79.63% (honey). FTIR-ATR results showed great spectral similarity of analyzed honey samples and small degree variations in both sugar and water content in nectar samples. The spectral data revealed distinctive differences in the chemical composition of individual honey sac contents with the most intensive and complex absorption envelope in the spectral region between 1175 and 950cm(-1) (glucose, fructose and sucrose absorption bands).

    Citrus fruits have been used as edible fruit and a component of traditional medicine for various diseases including cancer since ancient times. Herein, we investigated the anticancer activity of flavonoids of Citrus unshiu Marc. (FCM) focusing on anti-metastatic effects. We prepared FCM and performed experiments using MDA-MB-231 human breast cancer cells. FCM inhibited TNF-induced cancer cell adhesion to human umbilical vein endothelial cells (HUVECs) without showing any toxicity. FCM inhibited the expression of VCAM-1, but not of ICAM-1, on MDA-MB-231 cells as well as HUVECs. FCM inhibited protein kinase C (PKC) phosphorylation, but not Akt phosphorylation. FCM also inhibited cancer cell invasion in a dose-dependent manner, but not MMP-9 expression. In conclusion, this study suggested that FCM inhibits TNF-induced cancer cell adhesion to HUVECs by inhibiting VCAM-1 through inhibition of PKC, providing evidence that FCM have anti-metastatic activity by inhibiting adhesion molecules and invasion on human breast cancer cells.

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

    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.

    Fruits and vegetables contain numerous antioxidants, such as carotenoids. Recent epidemiologic studies have demonstrated that a high dietary consumption of fruit and vegetables rich in carotenoids or with high serum carotenoid concentrations results in lower risks of certain cancers, diabetes, and cardiovascular disease. These results indicate that absorbed carotenoids are stored in various organs. Previously, we found that β-cryptoxanthin, found especially in Satsuma mandarin (Citrus unshiu MARC.), is easily absorbed and can also survive for a relatively long time in the human body; however, little is known about the absorption, storage, and tissue distribution of β-cryptoxanthin. In this study, we measured serum and the content of β-cryptoxanthin in several rat tissues after chronic ingestion of Satsuma mandarin extract rich in β-cryptoxanthin. Rats were fed a standard commercial diet containing Satsuma mandarin extract (containing β-cryptoxanthin at 11.7 mg/kg diet) for eight weeks. After 3 h of fasting, serum, liver, spleen, kidney, lung, heart, testis, brain, and epididymal fat were collected. The concentrations of β-cryptoxanthin in serum and tissues were evaluated by high-performance liquid chromatography. There was a wide range in the tissue levels of β-cryptoxanthin; liver had the greatest value, with 1265.3 ng/g tissue, followed by spleen, kidney, lung, heart, brain, and testis. Epididymal fat had the lowest value, with 6.99 ng/g tissue. β-Cryptoxanthin was also detected in serum in a concentration of 5.76 ng/mL. These results indicate that β-cryptoxanthin is easily absorbed and accumulated in several organs.

    Whether prey retains antipredator behavior after a long period of predator relaxation is an important question in predator-prey evolution. Père David's deer have been raised in enclosures for more than 1200 years and this isolation provides an opportunity to study whether Père David's deer still respond to the cues of their ancestral predators or to novel predators. We played back the sounds of crows (familiar sound) and domestic dogs (familiar non-predators), of tigers and wolves (ancestral predators), and of lions (potential naïve predator) to Père David's deer in paddocks, and blank sounds to the control group, and videoed the behavior of the deer during the experiment. We also showed life-size photo models of dog, leopard, bear, tiger, wolf, and lion to the deer and video taped their responses after seeing these models. Père David's deer stared at and approached the hidden loudspeaker when they heard the roars of tiger or lion. The deer listened to tiger roars longer, approached to tiger roars more and spent more time staring at the tiger model. The stags were also found to forage less in the trials of tiger roars than that of other sound playbacks. Additionally, it took longer for the deer to restore their normal behavior after they heard tiger roars, which was longer than that after the trial of other sound playbacks. Moreover, the deer were only found to walk away after hearing the sounds of tiger and wolf. Therefore, the tiger was probably the main predator for Père David's deer in ancient time. Our study implies that Père David's deer still retain the memories of the acoustic and visual cues of their ancestral predators in spite of the long term isolation from natural habitat.

Père David's deer have been raised in enclosures for more than 1200 years and this isolation provides an opportunity to study whether Père David's deer still respond to the cues of their ancestral predators or to novel predators. We played back the sounds of crows (familiar sound) and domestic dogs (familiar non-predators), of tigers and wolves (ancestral predators), and of lions (potential naïve predator) to Père David's deer in paddocks, and blank sounds to the control group, and videoed the behavior of the deer during the experiment. We also showed life-size photo models of dog, leopard, bear, tiger, wolf, and lion to the deer and video taped their responses after seeing these models. Père David's deer stared at and approached the hidden loudspeaker when they heard the roars of tiger or lion. The deer listened to tiger roars longer, approached to tiger roars more and spent more time staring at the tiger model. The stags were also found to forage less in the trials of tiger roars than that of other sound playbacks. Additionally, it took longer for the deer to restore their normal behavior after they heard tiger roars, which was longer than that after the trial of other sound playbacks. Moreover, the deer were only found to walk away after hearing the sounds of tiger and wolf. Therefore, the tiger was probably the main predator for Père David's deer in ancient time. Our study implies that Père David's deer still retain the memories of the acoustic and visual cues of their ancestral predators in spite of the long term isolation from natural habitat.

  2. Metagenomic analysis of the microbial community in fermented grape marc reveals that Lactobacillus fabifermentans is one of the dominant species: insights into its genome structure.

    Grape marc used for the production of distilled beverages undergoes prolonged storage which allows alcoholic fermentation to occur. Harsh conditions including low pH, limited oxygen and nutrients, temperature fluctuations, and high ethanol concentrations imposed by that environment create a strong selective pressure on microorganisms. A detailed characterization of the bacterial community during two time points of the fermentation process was performed using high-throughput sequencing of the V3-V6 16S rDNA hypervariable regions. The results revealed a marked reduction in the number of bacterial species after 30 days of incubation and made it possible to identify those species that are able to grow in that extreme environment. The genome sequence of Lactobacillus fabifermentans, one of the dominant species identified, was then analyzed using shotgun sequencing and comparative genomics. The results revealed that it is one of the largest genomes among the Lactobacillus sequenced and is characterized by a large number of genes involved in carbohydrate utilization and in the regulation of gene expression. The genome was shaped through a large number of gene duplication events, while lateral gene transfer contributed to a lesser extent with respect to other Lactobacillus species. According to genomic analysis, its carbohydrate utilization pattern and ability to form biofilm are the main genetic traits linked to the adaptation the species underwent permitting it to grow in fermenting grape marc.

    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. Focusing on the implementation of the Affordable Care Act, David explored its opportunities and challenges especially in providing comprehensive and effective behavioral health services. A hallmark of his work has been his redirecting our attention to the most severely ill and those in greatest need. Less visible is the leadership and institution building endeavors and the many honors David has received. Copyright © 2016 by Duke University Press.

    The MARC Patient Simulator (MARC PS) enables researchers to observe the influence of handling errors on the radiant exposure that is delivered by light curing units (LCUs). Changes in the tilt angle and distance of the light guide exit face in relation to the surface of the composite increment have a distinct effect on the total amount of light delivered during polymerization and may cause insufficient conversion of the material. Therefore, the aim of the present study was to determine the influence of the tilt angle and distance of irradiance on the efficiency of light application by recording the total amount of energy using the anterior tooth sensor of the MARC PS. The influence of the tilt angle and distance of the light guide to the sensor surface on the delivered radiant exposure was examined for three different LCUs (Celalux 2 [C2], Bluephase [BP] and Translux Powerblue [TPB]). The measurements were performed for 20 s each with five different tilt angles (α=0°, 5°, 10°, 15°, 20°) and nine different distances (L=1, 2, 3, 4, 5, 6, 7, 8, 9 mm). For all LCUs, a distinct influence of the tilt angle on the delivered amount of fluence was found. At 0° tilt the C2 delivered a total light energy of 38.55 J/cm(2). By increasing the tilt of the light guide the amount of energy applied significantly decreased. At 20° tilt a reduction by 31.2% of the original light fluence was recorded. However, the C2 was the most powerful LCU measured. Even under optimum measurement conditions, the BP delivered a fluence of only 14.8 J/cm(2). At a tilt angle of 20°, though, the light sensor still registered 92.7% of the original output power. Under the same conditions, the TPB delivered 81.4%. With increasing distance of the light guide exit face to the surface of the sensor all LCUs showed a significant loss in delivered light energy. At a distance of 2mm the C2 showed a reduction by 46.7%, whereas total fluence of BP and TPB were reduced by 3.8% and 4.8%, respectively. The

    Performance in numerical classification tasks involving either parity or magnitude judgements is quicker when small numbers are mapped onto a left-sided response and large numbers onto a right-sided response than for the opposite mapping (i.e., the spatial-numerical association of response codes or SNARC effect). Recent research by Gevers et al. [Gevers, W., Santens, S., Dhooge, E., Chen, Q., Van den Bossche, L., Fias, W., & Verguts, T. (2010). Verbal-spatial and visuospatial coding of number-space interactions. Journal of Experimental Psychology: General, 139, 180-190] suggests that this effect also arises for vocal "left" and "right" responding, indicating that verbal-spatial coding has a role to play in determining it. Another presumably verbal-based, spatial-numerical mapping phenomenon is the linguistic markedness association of response codes (MARC) effect whereby responding in parity tasks is quicker when odd numbers are mapped onto left-sided responses and even numbers onto right-sided responses. A recent account of both the SNARC and MARC effects is based on the polarity correspondence principle [Proctor, R. W., & Cho, Y. S. (2006). Polarity correspondence: A general principle for performance of speeded binary classification tasks. Psychological Bulletin, 132, 416-442]. This account assumes that stimulus and response alternatives are coded along any number of dimensions in terms of - and + polarities with quicker responding when the polarity codes for the stimulus and the response correspond. In the present study, even-odd parity judgements were made using either "left" and "right" or "bad" and "good" vocal responses. Results indicated that a SNARC effect was indeed present for the former type of vocal responding, providing further evidence for the sufficiency of the verbal-spatial coding account for this effect. However, the decided lack of an analogous SNARC-like effect in the results for the latter type of vocal responding provides an important

    To examine factors associated with false-negative cardiovascular magnetic resonance (MR) perfusion studies within the large prospective Clinical Evaluation of MR imaging in Coronary artery disease (CE-MARC) study population. Myocardial perfusion MR has excellent diagnostic accuracy to detect coronary heart disease (CHD). However, causes of false-negative MR perfusion studies are not well understood. CE-MARC prospectively recruited patients with suspected CHD and mandated MR, myocardial perfusion scintigraphy, and invasive angiography. This subanalysis identified all patients with significant coronary stenosis by quantitative coronary angiography (QCA) and MR perfusion (1.5T, T1 -weighted gradient echo), using the original blinded image read. We explored patient and imaging characteristics related to false-negative or true-positive MR perfusion results, with reference to QCA. Multivariate regression analysis assessed the likelihood of false-negative MR perfusion according to four characteristics: poor image quality, triple-vessel disease, inadequate hemodynamic response to adenosine, and Duke jeopardy score (angiographic myocardium-at-risk score). In all, 265 (39%) patients had significant angiographic disease (mean age 62, 79% male). Thirty-five (5%) had false-negative and 230 (34%) true-positive MR perfusion. Poor MR perfusion image quality, triple-vessel disease, and inadequate hemodynamic response were similar between false-negative and true-positive groups (odds ratio, OR [95% confidence interval, CI]: 4.1 (0.82-21.0), P = 0.09; 1.2 (0.20-7.1), P = 0.85, and 1.6 (0.65-3.8), P = 0.31, respectively). Mean Duke jeopardy score was significantly lower in the false-negative group (2.6 ± 1.7 vs. 5.4 ± 3.0, OR 0.34 (0.21-0.53), P < 0.0001). False-negative cardiovascular MR perfusion studies are uncommon, and more common in patients with lower angiographic myocardium-at-risk. In CE-MARC, poor image quality, triple-vessel disease, and inadequate

    To evaluate the cost-effectiveness of diagnostic strategies for coronary heart disease (CHD) derived from the CE-MARC study. Cost-effectiveness analysis using a decision analytic model to compare eight strategies for the diagnosis of CHD. Secondary care out-patients (Cardiology Department). Patients referred to cardiologists for the further evaluation of symptoms thought to be angina pectoris. Eight different strategies were considered, including different combinations of exercise treadmill testing (ETT), single-photon emission CT (SPECT), cardiovascular magnetic resonance (CMR) and coronary angiography (CA). Costs expressed as UK sterling in 2010-2011 prices and health outcomes in quality-adjusted life-years (QALYs). The time horizon was 50 years. Based on the characteristics of patients in the CE-MARC study, only two strategies appear potentially cost-effective for diagnosis of CHD, both including CMR. The choice is between two strategies: one in which CMR follows a positive or inconclusive ETT, followed by CA if CMR is positive or inconclusive (Strategy 3 in the model); and the other where CMR is followed by CA if CMR is positive or inconclusive (Strategy 5 in the model). The more cost-effective of these two rests on the threshold cost per QALY gained below which health systems define an intervention as cost-effective. Strategy 3 appears cost-effective at the lower end of the threshold range used in the UK (£20 000 per QALY gained), while Strategy 5 appears cost-effective at the higher end of the threshold range (£30 000 per QALY). The results are robust to various sources of uncertainty although prior likelihood of CHD requiring revascularisation and the rate at which false negative patients are eventually appropriately identified do impact upon the results. The CE-MARC study showed that CMR had superior diagnostic accuracy to SPECT and concluded that CMR should be more widely used in the investigation of patients with CHD.

    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.

    SUMMARY Until fairly recently, mentally ill mothers were separated from their new-borns because of the potential danger to the baby. Over the past 50 years, however, we have learned more about the perinatal period, with the development of child psychiatry and interest in maternal postpartum disorders. This knowledge has led psychiatric departments to develop new ways to provide care without separating mentally ill mothers from their babies. Joint full-time admissions began in Great Britain in 1948. The first Mother-Baby Unit (MBU) in France opened in 1979 and in Belgium in 1990. In 2003, there are 17 MBUs in France and 3 in Belgium. From 1995 to 1998, Odile Cazas and Nine Glangeaud, working with a group of child and adult psychiatrists and psychologists, adapted the English Marcé Checklist to the French and Belgian health and child protective systems and added items useful for research.

    The influence of virulent and attenuated strains of Porcine Reproductive and Respiratory Syndrome Virus with defined genomic differences on trace element profile of MARC-145 cells was investigated to elucidate the process of infection in vitro. The concentrations of seven trace elements (Al, Cr, Mn, Ni, Fe, Cu, Zn) in infected and non-infected cells were determined. Although viral replication was similar in all cases, there were distinct features of difference in the trace element profiles (changes of concentrations of Ni, Mn, Fe) in infected cells. In particular, cells infected with the attenuated strain of PRRSV (NADC8-251) contained very low level of Ni, compared with its pathogenic counterpart NADC8-252K. The infection with the Lelystad strain also led to a moderately high level of this trace element.

    The volatile compounds produced by Debaryomyces hansenii NRRL Y-7426 during the fermentation of detoxified concentrated distilled grape marc hemicellulosic hydrolysates was analysed by GC-MS. Thirty-five compounds corresponding to ten groups of volatile compounds: terpenes, higher alcohols, C₆ alcohols, aldehydes, volatile acids, acetates, ethyl esters, volatile phenols, sulphur compounds and hydrocarbons were identified. The supplementation with commercial nutrients increased the concentration of 2-phenylethanol, a commercial flavour and fragrance compound, with a rose-like odour, employed in cosmetics and food industries; and other positive compounds to the aroma such as terpenes and ethyl esters. Non-supplemented media produced the highest content in higher alcohols, volatile acids, sulphur compounds and in the majority of hydrocarbons detected, meanwhile supplementation with vinasses hardly produced volatile compounds. Only four volatile compounds contributed directly to the aroma according to the OAVs values higher than 1. Finally, a PCA analysis allowed accounting for 100 % of the variance.

    Two- and three-dimensional metallosupramolecules shaped like a Star of David were synthesized by the self-assembly of a tetratopic pyridyl ligand with a 180° diplatinum(II) motif and Pd(II) ions, respectively. In contrast to other strategies, such as template-directed synthesis and stepwise self-assembly, this design enables the formation of 2D and 3D structures in one step and high yield. The structures were characterized by both one-dimensional ((1) H, (13) C, (31) P) and two-dimensional (COSY, NOESY, DOSY) NMR spectroscopy, ESI-MS, ion-mobility mass spectrometry (IM-MS), AFM, and TEM. The stabilities of the 2D and 3D structures were measured and compared by gradient tandem mass spectrometry (gMS(2) ). The high stability of the 3D Star of David was correlated to its high density of coordination sites (DOCS).

    Ice streams play a major role in the ice mass balance and in the reckoning of the global sea level; they have therefore been the object of wide scientific interest in the last three decades. During the 21st Italian Antarctic Expedition, in the austral summer 2005-06, we deployed a joint seismographic and geodetic network in the area of the David Glacier, Southern Victoria Land. This followed a similar experiment carried out in the same area during the austral summer 2003-04 (19th Expedition) which involved the deployment of a seismographic network which recorded significant microseismicity beneath the David Glacier, primarily occurring as a few small clusters. In the latest 2006-06 deployment 7 seismographic stations and 3 GPS geodetic receivers operated continuously for a period of 3 months (November 2006-early February 2006) in an area of about 100x50 square km around the David Glacier. The seismic stations were sited on rocky outcrops around the ice flow, and were all equipped with a broad-band seismometer and a digitizer. Contemporaneous geodetic GPS measurements were made on two points located on the glacial body: the first site close to the 2003-04 epicentres and to the David Glacier ice fall, the second site on the floating Drygalski Ice Tongue. A primary master GPS receiver for the kinematic processing was installed on a benchmark located on the Hughes Bluff rock outcrop. Several analyses are planned utilising the combined data sets. These include examining the temporal evolution in earthquake magnitude and locations and also the contemporaneous observation of both seismic activity and surface kinematics of the ice stream to possibly correlate the registered microseismicity with potential surges of the glacier, eventually affected by the Ross Sea tides. Here we present some details of the two temporary networks and preliminary results and implications.

    Interspecies hybrids provide unique opportunities for fundamental genetic analyses and for genetic improvement of farmed deer. We have bred F1 hybrids by artificial insemination of red deer hinds (Cervus elaphus) with semen from Père David's deer (Elaphurus davidianus). The male and female F1 Père David deer x red deer hybrids were fertile and in matings with red deer have produced over 300 viable backcross hybrids. DNA was collected from the backcross progeny as an international reference panel for gene linkage mapping and to investigate associations between segregating species-specific genetic markers and phenotypic traits. We have measured a range of phenotypic traits in the backcross hybrids and red deer. Several traits appear suitable for genetic analysis using mapped genetic markers, including gestation length, growth rate, live weight, head morphometrics, and tail length. Typically these traits show a large difference between Père David's deer and red deer and a high variance in the backcross so that many individuals have a phenotype outside the range observed in red deer.

    Due to the complex and distributed nature of biological research, our current biological knowledge is spread over many redundant annotation databases maintained by many independent groups. Analysts usually need to visit many of these bioinformatics databases in order to integrate comprehensive annotation information for their genes, which becomes one of the bottlenecks, particularly for the analytic task associated with a large gene list. Thus, a highly centralized and ready-to-use gene-annotation knowledgebase is in demand for high throughput gene functional analysis. The DAVID Knowledgebase is built around the DAVID Gene Concept, a single-linkage method to agglomerate tens of millions of gene/protein identifiers from a variety of public genomic resources into DAVID gene clusters. The grouping of such identifiers improves the cross-reference capability, particularly across NCBI and UniProt systems, enabling more than 40 publicly available functional annotation sources to be comprehensively integrated and centralized by the DAVID gene clusters. The simple, pair-wise, text format files which make up the DAVID Knowledgebase are freely downloadable for various data analysis uses. In addition, a well organized web interface allows users to query different types of heterogeneous annotations in a high-throughput manner. The DAVID Knowledgebase is designed to facilitate high throughput gene functional analysis. For a given gene list, it not only provides the quick accessibility to a wide range of heterogeneous annotation data in a centralized location, but also enriches the level of biological information for an individual gene. Moreover, the entire DAVID Knowledgebase is freely downloadable or searchable at http://david.abcc.ncifcrf.gov/knowledgebase/.

    Clostridium perfringens is an important pathogen causing sudden death syndrome, necrotic enteritis, and gas gangrene in ruminants, especially some deer species. Père David's deer (Elaphurus davidianus) is one of the world's rare species and is an endangered and protected species in China. Some Père David's deer in the Chinese Shishou Père David's Deer Preserve died due to C. perfringens infection. We investigated the toxin types and C. perfringens enterotoxin-positive (cpe(+)) strains of isolated C. perfringens in Père David's deer in China. We collected 155 fecal samples from the Beijing Nanhaizi Père David's Deer Park and the Jiangsu Dafeng Père David's Deer National Nature Reserve between July 2010 and July 2011. Bacteria isolated using blood agar and mannitol agar plates were identified by Gram staining and nested PCR for 16S rRNA. We isolated C. perfringens from 41 fecal samples and used PCR amplification of five toxin genes to identify the toxinotypes and the cpe(+) strains of C. perfringens. Twenty-one isolates were type A, 15 were type E, and five were type D. Fifteen isolates were cpe(+) strains, including eight that were type A and seven that were type E.

    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

    Studies have focused on foraging ecology of cattle egrets (Bubulcus ibis) and their selection of ungulate host species. However, few studies have been conducted at intraspecific levels, such as the sex/age class of a specific ungulate. In this study, the foraging behavior and intraspecific host selection of cattle egrets associated with Père David's deer (Elaphurus davidianus) were investigated at the Dafeng National Nature Reserve, China in summer 2011 and 2012. Egret-deer pairing status was analyzed and intraspecific host selection index was calculated. Cattle egrets preferred to feed with female deer compared with male deer and fawns. In contrast to solitary birds, cattle egrets following a deer benefited from a relatively low vigilance output, high foraging success, low energy expenditure, and high total foraging yields. These egrets also maximized benefits when they followed female deer compared with male deer and fawns. Our results further indicated that egrets likely preferred females because of the appropriate moving speed that allowed these egrets to follow and forage sufficiently and effectively. The males of Père David's deer were possibly more aggressive than the females during the rutting season, causing egrets to experience difficulty in accompaniment and feeding. Fawns were not preferred because they were usually motionless and insufficiently large to stir more insects. We did not find any behavioral differences in vigilance and feeding between juveniles and adults. Our results suggested that cattle egrets could obtain significant benefits from their association with Père David's deer, and these benefits were maximized when they followed female deer.

    Writing a study of psychologist David Boder's 1946 displaced persons (DP) interview project gave me a chance to further document the substantial early response to the Holocaust. This was clearly one important piece of my study, and one that was eminently straightforward. Yet much of the research on Boder's project at the point in time that I carried it out was elliptical, partly because the primary interview materials were coming to light at an astonishing pace, partly because the archive collections were virtually untapped, and partly because of the misconception of Boder and his interview project itself.

    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.

    This commentary on David Marks’ article on the Homeostatic Theory of Obesity and his Circle of Discontent mechanism for maintaining problematic eating behavior and obesity offers a perspective on the promise and potential of this theory. At the same time, we challenge the author to incorporate more of a process perspective into the theory. This would include greater exploration of how individuals enter and exit this hypothesized Circle of Discontent, how these mechanisms lead to obesity rather than other internalizing or externalizing disorders, and how the interactions among key variables differ for males and females and developmental stages.

By exploring two related yet distinct phenomena, well documented in the empirical psychological literature, that I call "shattering" and "fragmentation," I argue that when a woman is raped, it does matter that her rapist is male, given that her situation as a woman under patriarchy is partly constitutive of the harm that she suffers. © The Author(s) 2014.

    S93-31702 (3 April 1993) --- Astronaut David A. Wolf participates in training for contingency extravehicular activity (EVA) for the STS-58 mission. Behind Wolf, sharing the platform with him is astronaut Shannon W. Lucid. For simulation purposes, the two mission specialists were about to be submerged to a point of neutral buoyancy in the Johnson Space Center's (JSC) Weightless Environment Training Facility (WET-F). Though the Spacelab Life Sciences (SLS-2) mission does not include a planned EVA, all crews designate members to learn proper procedures to perform outside the spacecraft in the event of failure of remote means to accomplish those tasks.

    As a man with equal interests in science and science policy, David Baltimore has been at the forefront of many of the important debates that have shaped science since the 1970s. Very much engaged in the initial discussions about the use of recombinant DNA technology, Baltimore had a front-row seat as the biotechnology industry developed. He was also a major player in the decision that resulted in funding of the Human Genome Project by the National Institutes of Health (NIH). Baltimore discusses biotechnology, science education, and the need for a strong dialogue among scientists and scholars in the health policy community.

  16. 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

    The MARC project (methodology of art reproduction in color), funded by the EC and involving eight European partners, had the aim to improve the quality of reproduction in art catalogues and books. Those who are familiar with the nature of the problem will be pleased to hear this, because the color of reproductions often bears little resemblance to that of the original paintings. For the general public, as well as for the scholar, this has been an annoying, but nevertheless unavoidable characteristic of conventional photographic and printing techniques. With the advent of digital technology, came about the promise of revolutionary innovations which we regarded as a great challenge. Besides the numerous improvements and simplifications offered by digital techniques, we hope to be able to make use of the MARC digital image acquisition technology in order to replace the repeated photographing of paintings, thereby significantly reducing the burden placed upon them. Besides this, the digital image will be useful for many other purposes. As no camera was available with the resolution equivalent to a 24 cm by 18 cm Ektachrome film, the format usually used for high quality reproduction of paintings, one of the tasks of the project was to develop an electronic camera with 20,000 by 20,000 pixels and a color depth of 3 by 12 bits. In lack of charge coupled device (CCD) sensors which come even close to such a high resolution, a novel imaging technology combining micro- and macro-scanning with a CCD area sensor was developed. To avoid revolving color filters, this sensor is equipped with a color mosaic mask with filter characteristics closely matched to a linear combination of the XYZ spectral response curves defined by CIE 1931. The features of this camera are covered in great detail. The second step was to characterize the colorimetric response of the printing press. As the final result, a book 'Flamish Baroque Painting, Masterpieces of the Alte Pinakothek Munchen', with

    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.

    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.

    The effect of total dissolved gas (TDG) supersaturation on fish living downstream of dams is one of the main ecological risks of high dam construction. A strategy for mitigating the negative effects is needed urgently since many high dams are under construction in the upper reaches of the Yangtze River in China. Experiments on the hatching process of David's schizothoracin were carried out and the results show that the hatching rate decreased with increasing TDG levels, and that most eggs hatched within a very short time in the higher TDG saturation groups. By using a stereomicroscope, damages to the head, yolk sac, body, anus, etc. were found in larvae which hatched in TDG supersaturated water. Results show that the lesion rate increased with increasing TDG levels. Furthermore, 7-d-old David's schizothoracin were exposed to TDG supersaturated water levels of 100%, 105%, 110%, 115%, 120%, 125%, 130%, 135%, and 140% for testing their tolerance to TDG supersaturation. We found that the median lethal concentrations (LC50) for 13, 14, 20, 35, 52, 73, and 96 h exposure were 138%, 138%, 134%, 130%, 129%, 128%, and 126%, respectively. The median lethal times (LT50) were 7.49, 11.04, 19.25, and 35.38 h for exposure to water with TDG levels of 145%, 140%, 135%, and 130%, respectively.

    Biosynthesis of xylitol using the yeast Debaryomyces hansenii NRRL Y-7426 was carried out using distilled grape marc (DGM) hemicellulosic hydrolysates directly concentrated by vacuum evaporation or after detoxification with activated charcoal. The effect of nutrient supplementation with vinasses, corn steep liquor (CSL) or commercial nutrients was explored. Using crude concentrated hemicellulosic hydrolysates, the maximum xylitol concentration, 11.3 g/L, was achieved after 172 hr (Q ( xylitol ) = 0.066 g/L-hr; Y ( xylitol ) (/SC) = 0.21 g/g); meanwhile, using detoxified concentrated hydrolysates, the concentration increased up to 19.7 g/L after 72 hr (Q ( xylitol ) = 0.274 g/L-hr; Y ( xylitol ) (/SC) = 0.38 g/g). On the other hand, using crude or detoxified hydrolysates, the xylose-to-xylitol bioconversion was strongly affected by the addition of nutrients, suggesting that these hydrolysates present essential nutrients favouring the growth of D. hansenii.

    Network structures based on Star-of-David catenanes with multiple superior functionalities have been so far elusive, although numerous topologically interesting networks are synthesized. Here, a metal-organic framework featuring fused Star-of-David catenanes is reported. Two triangular metallacycles with opposite handedness are triply intertwined forming a Star-of-David catenane. Each catenane fuses with its six neighbors to generate a porous twofold intercatenated gyroid framework. The compound possesses exceptional stability and exhibits multiple functionalities including highly selective CO2 capture, high proton conductivity, and coexistence of slow magnetic relaxation and long-range ordering. © 2017 WILEY-VCH Verlag GmbH & Co.

    sufficiently close to any corrugated—and/or any smooth—surface and thus enforce a strong vdW-type adhesion; it exploits what is then essentially a contact force (dominated by the attraction exerted in the near-surface regions) to defy the pull of gravity on its own bulk. 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

Matthews (2001) have carefully examined the controversial issue of whether emotional intelligence (EI) should be classified as an intelligence and whether EI's constructs meet the same psychometric standards as general intelligence's constructs. This article casts their efforts into the framework of both historical and modern IQ-testing theory and research. It details David Wechsler's attempts to integrate EI into his tests and how his conception of a good clinician would be that of an emotionally intelligent clinician. Current theories and research on IQ also have a role in EI beyond what Roberts et al. described, including J. L. Horn's (1989) expanded model and A. R. Luria's (1966) neuropsychological research, and better criteria than the Armed Services Vocational Aptitude Battery should be used in future EI studies. The authors look forward to more research being conducted on EI, particularly in future performance-based assessments.

    Does it signify morally whether a deception is achieved by a lie or some other way? David Bakhurst has challenged my view that it can signify. Here I counter his criticisms--firstly, by clarifying the terminology: What counts as a lie? Secondly, by exploring further what makes lying wrong. Bakhurst maintains that lying is wrong in that it infringes autonomy--and other deceiving stratagems, he says, do so equally. I maintain that lying is wrong in that it endangers trust--and other types of deceiving stratagems do not do so equally. Lying to patients, I contend, is an abuse of their trust. Other forms of their intentional deception need not be so, although, in our autonomy-minded culture, they are likely to be so.

    Born of humble beginnings in a Scottish mill-town, David Livingstone would become one of the great explorers of the 19th century, traversing 30,000 miles of unknown Africa. His pioneering spirit and inquisitive mind brought knowledge and discoveries in the fields of tropical medicine, linguistics, botany, zoology, anthropology and geology. While it can be argued that Livingstone exhibited contradictions and shortcomings as a man, he nonetheless grasped the imagination of Victorian Britain and helped to change European attitudes towards Africa forever. His numerous endeavours were undertaken under the banner of divinely inspired missionary work -- 'If God has accepted my service, then my life is charmed till my work is done' (Livingstone D. Livingstone's Private Journals, 1851-53. London: Chatto & Windus, 1960:108). Yet whether it was indeed religion that truly motivated Livingstone, or rather that he used it as a vehicle for his other passions, is less certain.

    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.

    In this article, David Bittner explodes the myth, restated in Brideshead Revisited (1945), that Polynesians are "happy and harmless." 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.
