  2. Virginia Henderson and her timeless writings.

    Halloran, E J


    This paper provides a reflection on the written works of Miss Virginia Avenel Henderson. Miss Henderson is a nurse, a scientist, an artist and a quintessential human being--all traits which informed her written output. Nursing practice, research and education were all subjects of her extensive chronicle. The four-volume Nursing Studies Index is her contribution to nursing research. The Index was sandwiched between two revisions of Principles and Practice of Nursing (5th and 6th eds), the placement of which caused the Index to focus on practice and the Principles (6th ed.) to be based on research. The sixth edition of Principles, written with Gladys Nite and 17 contributors, is considered the most important single professional document written in the twentieth century. The book synthesizes nursing practice, education, theory and research in an age when many nurses are challenged by the seeming incongruity in these essential professional functions.

  3. Henderson-Hasselbalch Equation: Its History and Limitations

    Po, Henry N.; Senozan, N. M.


    Many students of chemistry have wondered if putting the mass action expression in logarithmic format should have warranted immortalization of the names Henderson and Hasselbalch. With focus on this question, this article examines the evolution of the Henderson-Hasselbalch equation and presents a critical evaluation of its usefulness. The discussion centers on the titration of a weak acid with sodium hydroxide. Approximate pH values obtained from the Henderson-Hasselbalch equation are compared with exact hydrogen ion concentrations and the percentage errors are displayed as a function of the acid dissociation constant and buffer composition (titration mixture).

  12. C. R. Henderson: farm boy, athlete, and scientist.

    Van Vleck, L D


    Charles R. Henderson was proud to be a product of a farm in Page County, Iowa. He was a one man track team in Coin, Iowa, and a brilliant student. He became a world class competitor in track at Iowa State College and, at the same time, compiled a top academic record. His early experiences set the stage for the exceptional contributions of his animal breeding career, which did not begin until he was nearly 40 yr of age, but which spanned 40 yr when he was the acknowledged leader in development of statistical methodology applied to animal breeding. His career goals were to find the best possible ways to analyze data and to provide the best genetic evaluations to the livestock industry. If the best could not be done because of computational limitations, then he would pragmatically work to find the best way that was possible. Only his interest in Cornell hockey overshadowed his enjoyment in listening to classical music. He was an avid sports fan, especially for the St. Louis Cardinals or any midwestern team against the New York Yankees. Midwestern trips during the weeks when the Drake Relays were held were as often as possible. Henderson's acknowledged scientific hero was Jay L. Lush, with whom he studied during his Ph.D. program at Iowa State College and with whom he shared similar talents and the intuition that made both of them leaders in the field of animal breeding.

  15. Design and planning of the Henderson Mine ventilation upgrade project

    Loring, D.M.; Shea, N.A. [Climax Molybdenum Co., Henderson Operations, Empire, CO (United States)


    The average molybdenum ore throughput at the Henderson Mine near Denver, Colorado increased significantly between 2003 and 2007. In response, the Climax Molybdenum Company updated the life-of-mine plan which resulted in significant changes to the ventilation requirements of the mine. This paper outlined the mine and ventilation planning efforts. The design options that were evaluated to upgrade the ventilation system were also described along with the final design that was chosen to support the updated mine plan. The mine uses an exhaust ventilation system in which ventilation is supplied through a service shaft, an intake shaft and a long ore haulage tunnel. Currently, air is exhausted through 2 exhaust shafts. The new reserve model that was completed in 2007 incorporated updated geologic information and mix/dilution models. An evaluation of the new life-of-mine plans and production sequences drove the development of a new ventilation plan that increased the airflow requirements of the mine. The primary design concerns were radon control; reduction of diesel particulate matter; silica dust; blasting and other gases; and climate control. Ventilation requirements were also updated based on the final exposure limits stipulated in the 2008 regulations of the Mine Safety and Health Administration. 4 refs., 11 tabs., 8 figs.

  17. Virginia Henderson's principles and practice of nursing applied to organ donation after brain death.

    Nicely, Bruce; DeLario, Ginger T


    Registered nurses were some of the first nonphysician organ transplant and donation specialists in the field, both in procurement and clinical arenas. Nursing theories are abundant in the literature and in nursing curricula, but none have been applied to the donation process. Noted nursing theorist Virginia Henderson (1897-1996), often referred to as the "first lady of nursing," developed a nursing model based on activities of living. Henderson had the pioneering view that nursing stands separately from medicine and that nursing consists of more than simply following physicians' orders. Henderson's Principles and Practice of Nursing is a grand theory that can be applied to many types of nursing. In this article, Henderson's theory is applied to the intensely focused and specialized area of organ donation for transplantation. Although organ donation coordinators may have backgrounds as physicians' assistants, paramedics, or other allied health professions, most are registered nurses. By virtue of the inherent necessity for involvement of the family and friends of the potential donor, Henderson's concepts are applied to the care and management of the organ donor, to the donor's family and friends, and in some instances, to the caregivers themselves.

The Virginia Henderson International Nursing Library has introduced both a new publishing paradigm for research and a new knowledge indexing strategy for improving electronic access to research knowledge (findings). The ability of oncology nursing to evolve, as an evidence-based practice, is largely dependent on access to research findings.

  19. Test of the rem-counter WENDI-II from Eberline in different energy-dispersed neutron fields

    Gutermuth, F.; Radon, T.; Fehrenbacher, G.; Siekmann, R.


    The neutron rem-counter WENDI-II from Eberline was tested in high-energy particle accelerator produced neutron fields. A radioactive 241 Am-Be(αn) source was used as a reference. The experimentally determined responses are compared to Monte-Carlo simulations of the response function done by R. H. Olsher et al. (2000). The energy spectra of the accelerator produced neutron fields were determined employing Monte-Carlo simulations, too. According to the simulations done by C. Birattari et al. (1998) and in this work these neutron fields exhibit large contributions to the ambient dose equivalent resulting from neutrons with kinetic energy of more than 20 MeV up to a few 100 MeV. The WENDI-II detector proved to show a response of approximately 3.10 9 pulses per Sievert ambient dose equivalent. Considering the experimental and statistical uncertainties the results are consistent with the assumption that the dose response of the WENDI-II reproduces quite accurately the function for the ambient dose equivalent of the ICRP 74

  1. Hinduism’s Four Stages of Life in Saul Bellow’s Henderson the Rain King

    Manimangai Mani


    Full Text Available The oldest of Hindu’s philosophical writings, the Rig Veda, which came to being about 4500 BC underlined that, the cause of all misery that befalls  mankind  is his/her desire; or more promptly said, his/her attachment to the desire. In Hinduism, this physical plane is just a stage with life itself is nothing more than a play. The stage is set in such a way to enable the souls which took the human form to evolve and to find the enlightenment and ultimately to become one with the creator. All the material elements including the complex relationship found in this plane is nothing but a mere illusion. This study aims to explore elements of Hindu philosophy in Saul Bellow’s novel, Henderson the Rain King (1976. Eugene Henderson, the main character in this novel is portrayed as drowning in the materialistic world. Being constantly mugged by a desirable voice within him whispering, I want, I want, it is not an irony if he generated a sense of uselessness and emptiness. This study shows how Henderson’s decision to go to Africa to find the meaning of life coincides with the Hindu philosophy of the four stages of life; Brahmacharya (celibacy, Grahasthya (householdership, Vanaprastha (detachment in attachment and Sanyas (seclusion.  Henderson comes to realization in his third stage and proceeds to the fourth stage. Henderson is taught to eradicate fear and to break the cycle of desire. Towards the end, Henderson realises that the voice was actually referring to, “He wants, She wants and They want”. The voice was actually echoing the desires of mankind.

  2. Henderson Deep Underground Science and Engineering Lab: Unearthing the secrets of the Universe, underground

    Jung, C.K.


    The Henderson Mine near Empire, Colorado is proposed to be the site to host a Deep Underground Science and Engineering Laboratory (DUSEL), which will have a rich program for forefront research in physics, biology, geosciences, and mining engineering. The mine is owned by the Climax Molybdenum Company (CMC). It is located about 50 miles west of Denver and is easily accessible via major highways. The mine is modern and has extensive infrastructure with reserve capacity well-suited to the demands of DUSEL. CMC owns all land required for DUSEL, including the tailings site. It also has all environmental and mining permits required for DUSEL excavation, core drilling, and rock disposal. The mine owners are enthusiastic supporters of this initiative. In support of the Henderson DUSEL project, the State of Colorado has pledged substantial funding for surface construction.

  8. Nursing the community, a look back at the 1984 dialogue between Virginia A. Henderson and Sherry L. Shamansky.

    Abrams, Sarah E


    Dr. Sherry L. Shamansky, one of the founding editors of Public Health Nursing, interviewed renowned 20th-century leader, Virginia Avenal Henderson (1897-1996), then research associate emeritus at Yale University School of Nursing, about the nursing of "aggregates." Their discussion, originally published in Public Health Nursing, in 1984 (Vol. 1, No. 4), highlights Henderson's views about the scope of nursing, health care organization and funding, and perceived tension between direct care of the sick in the community and preventive activities directed toward communities or populations at risk. Readers familiar with Henderson's influential definition of nursing may find her responses to interview questions helpful in understanding her view of the opportunities and challenges faced by public or community health nurses of the time.

  10. Julia Henderson: in spite of opposition more and more people are practicing.


    In this interview Julia Henderson responds that since the 2nd half of the 1950s the international community has become aware that the increasing world population has decreased world resources. She reports that of the developing continents of Asia, Latin America and Africa, the crisis in Asia is the most severe because there the ratios of population to arable land are the worst. Henderson indicates that even where there is no national policy concerning family planning, as in most countries of Latin America, people are practicing birth control regardless. 30 countries now have official policies supporting family planning in their development plans. Another 30 countries have asked their ministers of health and voluntary agencies to deal with the problem. However, numerous other countries are simply avoiding the issue and tolerating the efforts of the International Planned Parenthood Federation. In over 100 countries with either official or unofficial programs, political leaders have recognized that a large population no longer means power. The quality of the population and the strength of the economy have become more important than numbers. The status of women in developing countries affects their use of family planning; most will not practice birth control without their husband's consent. The willingness of men to have vasectomies varies according to the culture. Vasectomy has become acceptable among a number of groups in India, Pakistan, England, and the U.S. The International Planned Parenthood Federation recognizes that abortion is still the major birth control method in developing countries. The objective is to decrease the number of abortions and the number of maternal deaths resulting from illegal abortions by offering safe, efficient and reliable methods of contraception. Regarding abortion procedures, evidence indicates that the vacuum aspiration method of abortion is a safer and more humane procedure.

  11. Potential for Nitrogen Fixation and Nitrification in the Granite-Hosted Subsurface at Henderson Mine, CO

    Swanner, Elizabeth D.; Templeton, Alexis S.


    The existence of life in the deep terrestrial subsurface is established, yet few studies have investigated the origin of nitrogen that supports deep life. Previously, 16S rRNA gene surveys cataloged a diverse microbial community in subsurface fluids draining from boreholes 3000 feet deep at Henderson Mine, CO, USA (Sahl et al., 2008). The prior characterization of the fluid chemistry and microbial community forms the basis for the further investigation here of the source of NH4+. The reported fluid chemistry included N2, NH4+ (5–112 μM), NO2− (27–48 μM), and NO3− (17–72 μM). In this study, the correlation between low NH4+ concentrations in dominantly meteoric fluids and higher NH4+ in rock-reacted fluids is used to hypothesize that NH4+ is sourced from NH4+-bearing biotite. However, biotite samples from the host rocks and ore-body minerals were analyzed by Fourier transform infrared (FTIR) microscopy and none-contained NH4+. However, the nitrogenase-encoding gene nifH was successfully amplified from DNA of the fluid sample with high NH4+, suggesting that subsurface microbes have the capability to fix N2. If so, unregulated nitrogen fixation may account for the relatively high NH4+ concentrations in the fluids. Additionally, the amoA and nxrB genes for archaeal ammonium monooxygenase and nitrite oxidoreductase, respectively, were amplified from the high NH4+ fluid DNA, while bacterial amoA genes were not. Putative nitrifying organisms are closely related to ammonium-oxidizing Crenarchaeota and nitrite-oxidizing Nitrospira detected in other subsurface sites based upon 16S rRNA sequence analysis. Thermodynamic calculations underscore the importance of NH4+ as an energy source in a subsurface nitrification pathway. These results suggest that the subsurface microbial community at Henderson is adapted to the low nutrient and energy environment by their capability of fixing nitrogen, and that fixed nitrogen may support subsurface biomass via

  12. The 100th anniversary of the invention of pH (1909-2009 - Part II. Was it really necessary to replace the Henderson equation with that of Henderson-Hasselbalch?

    Francesco Sgambato


    Full Text Available Introduction: The year 2009 marked the centenary of the ‘‘invention’’ of the concept of pH by the Danish chemist-mathematician Søren Peder Lauritz Sørensen (1868-1939, who was working at the time in the chemistry laboratories of the Carlsberg Brewery in Copenhagen. The occasion provides an opportunity to re-examine a concept that is crucial for the understanding of human life–—namely, acid-base balance. This article provides an overview of acid-base pathophysiology and the historical events that led from the simple equation of Henderson to the much more complex one developed by Hasselbalch. Conclusions: The authors conclude that the issue of acid-base balance would be easier to understand, more exciting, and even more pleasant if it were taught without recourse to the infamously abstruse Henderson-Hasselbalch equation. Unquestionably, the whole rationale underlying the understanding and clinical application of this vital concept is already inherent in the simpler, more manageable formula of Henderson (without logs, which is both useful and sufficient for use in medical school curricula.

  13. A discussion of radon and the mitigation strategy at the Henderson Mine

    Loring, D.M.; Meisburger, E.P. IV


    The geology at the Henderson molybdenum mine near Denver, Colorado makes radon a ventilation challenge. Unforeseen events can occur due to the dynamic nature of caving mining. As such, the Climax Molybdenum Company has adopted proper ventilation, monitoring and control strategies at the mine to mitigate concerns regarding radon. Due to the granitic ore and presence of trace uranium mineralization, radon daughters are generated and make their way through the caved orebody to drawpoints on the production level. This paper described historical geological events which involved reaction by the ventilation group to mitigate higher-than-normal radon concentrations, with particular reference to the causes, responses and planning to avoid similar issues in the future. The radon control strategy involves 3 items, notably negative pressure on the cave through regulators or fans connecting the broken ore of the cave to an isolated main exhaust drift; isolation of the cave through bulkheading of all intake air sources to the caved ore; and positive pressurization of the undercut level through forcing fans in the drill drifts so that pressure can be maintained in the cave, thus preventing radon daughters from leaking into the work area. 7 refs., 1 tab., 9 figs.

  14. Components of an Anticancer Diet: Dietary Recommendations, Restrictions and Supplements of the Bill Henderson Protocol

    Laurie Heilman Bell


    Full Text Available The use of complementary and alternative medicines including dietary supplements, herbals and special diets to prevent or treat disease continues to be popular. The following paper provides a description of an alternative dietary approach to the self-management and treatment of cancer, the Bill Henderson Protocol (BHP. This diet encourages daily intake of raw foods, a combination of cottage cheese and flaxseed oil and a number of supplements. Some foods and food groups are restricted (e.g., gluten, meat, dairy. Early background theory that contributed to the protocol’s development is presented as is a summary of relevant evidence concerning the anti-cancer fighting properties of the individual components. Supplement intake is considered in relation to daily recommended intakes. Challenges and risks to protocol adherence are discussed. As with many complementary and alternative interventions, clear evidence of this dietary protocol’s safety and efficacy is lacking. Consumers of this protocol may require guidance on the ability of this protocol to meet their individual nutritional needs.

  16. Surficial Geologic Map of the Evansville, Indiana, and Henderson, Kentucky, Area

    Moore, David W.; Lundstrom, Scott C.; Counts, Ronald C.; Martin, Steven L.; Andrews, William M.; Newell, Wayne L.; Murphy, Michael L.; Thompson, Mark F.; Taylor, Emily M.; Kvale, Erik P.; Brandt, Theodore R.


    The geologic map of the Evansville, Indiana, and Henderson, Kentucky, area depicts and describes surficial deposits according to their origin and age. Unconsolidated alluvium and outwash fill the Ohio River bedrock valley and attain maximum thickness of 33-39 m under Diamond Island, Kentucky, and Griffith Slough, south of Newburgh, Indiana. The fill is chiefly unconsolidated, fine- to medium-grained, lithic quartz sand, interbedded with clay, clayey silt, silt, coarse sand, granules, and gravel. Generally, the valley fill fines upward from the buried bedrock surface: a lower part being gravelly sand to sandy gravel, a middle part mostly of sand, and a surficial veneer of silt and clay interspersed with sandy, natural levee deposits at river's edge. Beneath the unconsolidated fill are buried and discontinuous, lesser amounts of consolidated fill unconformably overlying the buried bedrock surface. Most of the glaciofluvial valley fill accumulated during the Wisconsin Episode (late Pleistocene). Other units depicted on the map include creek alluvium, slackwater lake (lacustrine) deposits, colluvium, dune sand, loess, and sparse bedrock outcrops. Creek alluvium underlies creek floodplains and consists of silt, clayey silt, and subordinate interbedded fine sand, granules, and pebbles. Lenses and beds of clay are present locally. Silty and clayey slackwater lake (lacustrine) deposits extensively underlie broad flats northeast of Evansville and around Henderson and are as thick as 28 m. Fossil wood collected from an auger hole in the lake and alluvial deposits of Little Creek, at depths of 10.6 m and 6.4 m, are dated 16,650+-50 and 11,120+-40 radiocarbon years, respectively. Fossil wood collected from lake sediment 16 m below the surface in lake sediment was dated 33,100+-590 radiocarbon years. Covering the hilly bedrock upland is loess (Qel), 3-7.5 m thick in Indiana and 9-15 m thick in Kentucky, deposited about 22,000-12,000 years before present. Most mapped surficial

  17. Analysis of the accidental explosion at Pepcon, Henderson, Nevada, May 4, 1988

    Reed, J.W.


    Several hours of fire and numerous explosions destroyed the Pacific Engineering Company plant in Henderson, Nevada, that manufactured ammonium perchlorate (AP) for rocket fuel. This incident began about 1130 PDT on May 4, 1988, with a fire in their Batch House that grew out of control and caused a first large explosion at about 1153 PDT. The final and largest explosion occurred about 1157 PDT. Damages to the surrounding community were surveyed and interpreted as airblast overpressures versus distances, which allowed an estimate of 1-kiloton nuclear free-air-burst for the equivalent explosion yield. This could be reproduced by 250-tons TNT burst on the ground surface. Weather reports were obtained from the National Weather Services which indicated somewhat enhanced airblast propagation downwind toward northerly directions and attenuated airblast propagations upwind in southerly directions. It was impossible, for lack of winds aloft information below about 500 m above ground, to determine whether there was any atmospheric acoustic airblast focusing. Several seismic recordings in Las Vegas showed the greatest ground motion resulted from the airblast wave passage, traveling at near acoustic speed. Ground wave arrival times were not sufficiently precise to allow seismic speed interpretations. Of the 4000 tons of AP apparently stored in and around the plant, it appears that about 1500 tons detonated in the largest explosion. This leads to a conclusion that the TNT airblast equivalence factor for AP is near 1/6. An independent estimate, based on analysis of more ideal close-in structural deformations, suggested an equivalence factor of 1/3. 25 refs., 12 figs., 14 tabs.

  18. The Bilirubin Binding Panel: A Henderson-Hasselbalch Approach to Neonatal Hyperbilirubinemia.

    Ahlfors, Charles E


    Poor plasma bilirubin binding increases the risk of bilirubin neurotoxicity in newborns with hyperbilirubinemia. New laboratory tests may soon make it possible to obtain a complete bilirubin binding panel when evaluating these babies. The 3 measured components of the panel are the plasma total bilirubin concentration (B Total ), which is currently used to guide clinical care; the bilirubin binding capacity (BBC); and the concentration of non-albumin bound or free bilirubin (B Free ). The fourth component is the bilirubin-albumin equilibrium dissociation constant, K D , which is calculated from B Total , BBC, and B Free The bilirubin binding panel is comparable to the panel of components used in the Henderson-Hasselbalch approach to acid-base assessment. Bilirubin binding population parameters (not prospective studies to determine whether the new bilirubin binding panel components are better predictors of bilirubin neurotoxicity than B Total ) are needed to expedite the clinical use of bilirubin binding. At any B Total , the B Free and the relative risk of bilirubin neurotoxicity increase as the K D /BBC ratio increases (ie, bilirubin binding worsens). Comparing the K D /BBC ratio of newborns with B Total of concern with that typical for the population helps determine whether the risk of bilirubin neurotoxicity varies significantly from the inherent risk at that B Total Furthermore, the bilirubin binding panel individualizes care because it helps to determine how aggressive intervention should be at any B Total , irrespective of whether it is above or below established B Total guidelines. The bilirubin binding panel may reduce anxiety, costs, unnecessary treatment, and the likelihood of undetected bilirubin neurotoxicity. Copyright © 2016 by the American Academy of Pediatrics.

    Full Text Available La atención a la salud de las personas ancianas es actualmente un ámbito extraordinariamente dinámico y cambiante, tanto en lo referente a las necesidades de los clientes, como en los requerimientos profesionales necesarios para dar respuestas adecuadas en un medio extremadamente permeable a los acontecimientos científicos, legales, familiares, sanitarios, políticos, etc. Dentro del equipo multidisciplinar, en los ambitos específicos de atención gerontológica y a la comunidad, la enfermera es el líder indiscutible del equipo, ya que es el único profesional preparado y entrenado para trabajar según un plan de cuidados integral enfocado a la persona. Los modelos de enfermería nos aportan el sistema de valores desde el cual la enfermera afronta su rol, evalúa los problemas de salud y planifica sus objetivos específicos, desde el rol autónomo y desde el rol de colaboración con otros profesionales de la salud. El Modelo Henderson, sus valores y postulados se adaptan muy especialmente a la atención gerontológica y lo hacen comprensible y compatible con los objetivos interdisciplinarios, reforzando el liderazgo de la enfermera dentro del equipo de atención. El objetivo de este trabajo es aportar una visión gerontológica de los conceptos básicos del Modelo Henderson y del proceso de atención de enfermería, basados en la reflexión sobre la práctica clínica.Nowadays, elderly people care has become an extremely dynamic field as it is changing both in the patient's needs and in the professional requests needed to provide the right answers in a modern environment, which is extremely linked to scientific, legal, familiar, health and political changes. Within the multidisciplinary team in the specific fields of gerontology and community care, the nurse is the unquestionable leader, as this is the only qualified professional who is trained to follow a whole care plan aimed at every patient.

  3. An MIS 5a/b to MIS 3 bog sequence from Henderson Bay, northern New Zealand

    D'Costa, D.; Wallis, I.


    A discontinuous Late Pleistocene pollen record from an eroding coastal cliff section at Henderson Bay on the east coast of Northland, New Zealand, reveals changes in vegetation composition and associated palaeosol development under both stadial and interstadial climatic conditions ascribed to the last interglacial-glacial cycle, probably MIS (Marine Isotope Stage) 5a/b to early MIS 3. An increase in charcoal towards the top of the sequence is believed to be due to natural rather than anthropogenic ignition sources which resulted in the development of scrub rather than forest vegetation. The sequence is capped by gravel previously inferred to have been emplaced by tsunami event(s) some time after early MIS 3. A lack of Agathis pollen in our sequence despite unequivocal evidence for the parent trees (gum) strengthens a call for caution when inferring climatic conditions from the abundance of Agathis pollen in New Zealand pollen records.

  7. Tri-State Synfuels Project Review: Volume 12. Fluor project status. [Proposed Henderson, Kentucky coal to gasoline plant; engineering


    The purpose of this report is to document and summarize activities associated with Fluor's efforts on the Tri-State Synfuels Project. The proposed facility was to be coal-to-transport fuels facility located in Henderson, Kentucky. Tri-State Synfuels Company was participating in the project as a partner of the US Department of Energy per terms of a Cooperative Agreement resulting from DOE's synfuel's program solicitation. Fluor's initial work plan called for preliminary engineering and procurement services to the point of commitment for construction for a Sasol Fischer-Tropsch plant. Work proceeded as planned until October 1981 when results of alternative coal-to-methanol studies revealed the economic disadvantage of the Synthol design for US markets. A number of alternative process studies followed to determine the best process configuration. In January 1982 Tri-State officially announced a change from Synthol to a Methanol to Gasoline (MTG) design basis. Further evaluation and cost estimates for the MTG facility eventually led to the conclusion that, given the depressed economic outlook for alternative fuels development, the project should be terminated. Official announcement of cancellation was made on April 13, 1982. At the time of project cancellation, Fluor had completed significant portions of the preliminary engineering effort. Included in this report are descriptions and summaries of Fluor's work during this project. In addition location of key project data and materials is identified and status reports for each operation are presented.

  9. Pre-eruptive conditions of the Hideaway Park topaz rhyolite: Insights into metal source and evolution of magma parental to the Henderson porphyry molybdenum deposit, Colorado

    Mercer, Celestine N.; Hofstra, Albert H.; Todorov, Todor I.; Roberge, Julie; Burgisser, Alain; Adams, David T.; Cosca, Michael A.


    The Hideaway Park tuff is the only preserved extrusive volcanic unit related to the Red Mountain intrusive complex, which produced the world-class Henderson porphyry Mo deposit. Located within the Colorado Mineral Belt, USA, Henderson is the second largest Climax-type Mo deposit in the world, and is therefore an excellent location to investigate magmatic processes leading to Climax-type Mo mineralization. We combine an extensive dataset of major element, volatile, and trace element abundances in quartz-hosted melt inclusions and pumice matrix glass with major element geochemistry from phenocrysts to reconstruct the pre-eruptive conditions and the source and evolution of metals within the magma. Melt inclusions are slightly peraluminous topaz rhyolitic in composition and are volatile-charged (≤6 wt % H2O, ≤600 ppm CO2, ∼0·3–1·0 wt % F, ∼2300–3500 ppm Cl) and metal-rich (∼7–24 ppm Mo, ∼4–14 ppm W, ∼21–52 ppm Pb, ∼28–2700 ppm Zn, shallow ascent and eruption. Filter pressing, crystal settling, magma recharge and mixing of less evolved rhyolite melt, and volatile exsolution were important processes during magma evolution; the low estimated viscosities (∼105–1010 Pa s) of these H2O- and F-rich melts probably enhanced these processes. A noteworthy discrepancy between the metal contents in the pumice matrix glass and in the melt inclusions suggests that after quartz crystallization ceased upon shallow magma ascent and eruption, the Hideaway Park magma exsolved an aqueous fluid into which Mo, Bi, Ag, Zn, Mn, Cs, and Y strongly partitioned. Given that the Henderson deposit contains anomalous abundances of not only Mo, but also W, Pb, Zn, Cu, Bi, Ag, and Mn, we suggest that these metals were sourced from similar fluids exsolved from unerupted portions of the same magmatic system. Trace element ratios imply that Mo was sourced deep, from either the lower crust or metasomatized mantle. The origin of sulfur remains unresolved

  10. A revision of "blanket-hermit crabs" of the genus Paguropsis Henderson, 1888, with the description of a new genus and five new species (Crustacea, Anomura, Diogenidae).

    Lemaitre, Rafael; Rahayu, Dwi Listyo; Komai, Tomoyuki


    For 130 years the diogenid genus Paguropsis Henderson, 1888 was considered monotypic for an unusual species, P. typica Henderson, 1888, described from the Philippines and seldom reported since. Although scantly studied, this species is known to live in striking symbiosis with a colonial sea anemone that the hermit can stretch back and forth like a blanket over its cephalic shield and part of cephalothoracic appendages, and thus the common name "blanket-crab". During a study of paguroid collections obtained during recent French-sponsored biodiversity campaigns in the Indo-West Pacific, numerous specimens assignable to Paguropsis were encountered. Analysis and comparison with types and other historical specimens deposited in various museums revealed the existence of five undescribed species. Discovery of these new species, together with the observation of anatomical characters previously undocumented or poorly described, including coloration, required a revision of the genus Paguropsis . The name Chlaenopagurus andersoni Alcock & McArdle, 1901, considered by Alcock (1905) a junior synonym of P. typica , proved to be a valid species and is resurrected as P. andersoni (Alcock, 1899). In two of the new species, the shape of the gills, length/width of exopod of maxilliped 3, width and shape of sternite XI (of pereopods 3), and armature of the dactyls and fixed fingers of the chelate pereopods 4, were found to be characters so markedly different from P. typica and other species discovered that a new genus for them, Paguropsina gen. n. , is justified. As result, the genus Paguropsis is found to contain five species: P. typica , P. andersoni , P. confusa sp. n. , P. gigas sp. n. , and P. lacinia sp. n. Herein, Paguropsina gen. n. , is proposed and diagnosed for two new species, P. pistillata gen. et sp. n. , and P. inermis gen. et sp. n. ; Paguropsis is redefined, P. typica and its previously believed junior synonym, P. andersoni , are redescribed. All species are

    Manuela Borges Gavaza Barbosa


    Full Text Available JUSTIFICATIVA E OBJETIVOS: Rever estratégias de avaliação da acidose metabólica dando ênfase ao método de Stewart-Fencl-Figge versus a abordagem tradicional de Henderson-Hasselbalch. CONTEÚDO: A acidose metabólica é um distúrbio comum em pacientes criticamente enfermos, sendo importante causa de depressão da função miocárdica e sensível indicador de má perfusão tissular. Tradicionalmente, é avaliada através do método de Henderson-Hasselbalch no qual a gasometria arterial fornece informações sobre a existência e o tipo de distúrbio ácido-básico. Porém, nem sempre, esse método é capaz de explicar os seus mecanismos causais e, por isso, muitos estudos têm sido feitos na tentativa de melhorar sua interpretação. O método de Stewart-Fencl-Figge, calculado através de fórmula matemática, em que além da gasometria arterial, são utilizados níveis séricos de vários eletrólitos, lactato e albumina, nos fornece informações mais fidedignas permitindo detectar anormalidades metabólicas mistas e estimar a magnitude de cada componente, principalmente na presença de múltiplas disfunções orgânicas. Nesses pacientes, a presença de ânions não mensurados no plasma é importante mecanismo de acidose metabólica e sua detecção precoce é fundamental para se evitar efeitos deletérios sobre o organismo. CONCLUSÕES: A abordagem tradicional de Henderson-Hasselbalch falha em analisar os mecanismos da acidose metabólica e possui muitas variáveis que interferem no seu resultado, principalmente no paciente criticamente enfermo. O método de Stewart-Fencl-Figge proporciona abordagem mais completa para avaliação da acidose metabólica, sugerindo seus mecanismos e orientando a terapêutica. Como alternativa, o anion gap corrigido pela albumina e lactato parece ser tão eficiente em identificar a presença de anions não mensurados quanto o método de Stewart.BACKGROUND AND OBJECTIVES: To review strategies of assessment

    Jorge Wilker Bezerra Clares


    Full Text Available This is an experience report that aims to describe the application of the nursing process to an institutionalized elderly, based on Virginia Henderson’s theory. The case study was developed in a long-stay institution for the elderly in Fortaleza, Ceará, Brazil, from May to August 2010, by filling out a form, physical examination and observation. Identifying the needs of elimination, communication, recreation and learning allowed to raise the nursing diagnoses, respectively: urge urinary incontinence; impaired social interaction; diversional activity deficit; and impaired memory. The nursing interventions were directed to the health and independence of the elderly. The application of systematic nursing care impacted positively on the health of the elderly, demonstrating the applicability of the nursing systematization based on Henderson’s theory in the scenery in which the study was developed.

    Leach, Victor A.; Weller, Steven; Redmayne, Mary


    The measurement and collection of radiofrequency (RF) exposure data in Australian classrooms is important and ARPANSA should be applauded for undertaking the much-needed research reported in the above paper. However, the paper presented is very misleading and demonstrates how more care should have been taken when planning and designing the Wi-Fi survey. The survey results presented by Karipidis et al. are of little practical use and are misleading when it comes to determining what RF power density levels are realistically experienced by students in a 'typical' classroom setting. We would also like to highlight the opening sentence of the discussion section; the authors refer to this being a 'comprehensive' survey. We believe this claim is overstated as shown in this letter

Supplemental breast MRI is sometimes used in addition to mammography despite the lack of clinical evidence for it. Breast imaging after cancer treatment is an emotionally charged experience, an important part of survivorship care, and a topic about which limited patient information exists. We assessed women’s experiences and preferences about breast cancer surveillance imaging with the goal of determining where gaps in care and knowledge could be filled. Participants and methods: We conducted six focus groups with a convenience sample of 41 women in California, North Carolina, and New Hampshire (USA. Participants were aged 38–75 years, had experienced stage 0–III breast cancer within the previous 5 years, and had completed initial treatment. We used inductive thematic analysis to identify key themes from verbatim transcripts. Results: Women reported various types and frequencies of surveillance imaging and a range of surveillance imaging

  2. Predation by Corallus annulatus (Boidae on Rhynchonycteris naso (Emballonuridae in a lowland tropical wet forest, Costa Rica

    Lewis, Todd R.


    Full Text Available Corallus annulatus (Northern Annulated Tree-boa is a little-studied tropical Boid occurring disjunctively throughout Central America and tropical South America in mostly lowland tropical moist and wet forests (Holdridge, 1967; Stafford & Henderson, 1996; Smith & Acevedo, 1997; Henderson et al., 2001. Prior to this report and to the best of our knowledge, small rodents were the only documented prey for wild specimens of C. annulatus (Henderson et al., 1995. Caño Palma Biological Station is situated on the northeast coast of Costa Rica approximately 8 km north of Tortuguero. C. annulatus has previously been recorded from Manicaria forest at Caño Palma (Myers, 1990; Burger, 2001. On 12th January 2002 and 15th July 2003 we found two separate C. annulatus specimens with Rhynchonycteris naso (Proboscis bat in their stomachs.

  3. Comportamento higroscópico do extrato seco de urucum (Bixa Orellana L Hygroscopic behavior of annatto (Bixa Orellana L dried extract

    George Carlos dos Santos Anselmo


    Full Text Available Neste trabalho, objetivou-se determinar a higroscopicidade do urucum na forma de extrato seco. Neste estudo foram obtidas as atividades de água do extrato seco de urucum para as temperaturas de 10 a 50ºC e teores de água entre 6 e 22% base úmida. A metodologia empregada para as determinações foi o método dinâmico em que se utilizou o equipamento Thermoconstanter Novasina TH-2. Para os resultados experimentais aplicaram-se as equações propostas por Henderson modificada por Thompson e Henderson modificada por Cavalcanti Mata e Peleg. Por meio das análises dos parâmetros encontrados concluiu-se que a equação que melhor se ajusta aos dados experimentais é a equação de Henderson modificada por Cavalcanti Mata e que as isotermas de adsorção de água do extrato de urucum seco se comportaram sigmoidalmente, sendo consideradas do tipo II.The objective of this work was to verify the higroscopicity of annatto seeds in the dry extract form. The isotherms were determined by the dynamic method with the Thermoconstanter Novasina TH-2 equipment. The equilibrium temperatures were 10, 20, 30, 40 and 50 ºC to range of moisture content between 6 and 22%, wet basis. The equations proposed by Henderson modified by Thompson and Henderson modified by Cavalcanti Mata and Peleg were applied to the experimental data. Through the gotten parameters found concluded that the best equation to represent the experimental data is the Henderson equations modified by Cavalcanti Mata. It was also concluded that hygroscopic equilibrium isotherms of annatto seeds presented sigmoid forms, considered type II.

  15. Translation and validation of the Malay Acceptance of Cosmetic Surgery Scale.

    Swami, Viren


    The present study examined the psychometric properties of a Malay translation of the Acceptance of Cosmetic Surgery Scale (ACSS; Henderson-King & Henderson-King, 2005). A total of 373 Malaysian women completed the ACSS along with measures of ideal-actual weight discrepancy, body appreciation, sociocultural attitudes toward appearance, self-esteem, life satisfaction, and demographics. Results showed that the Malay ACSS was best reduced to a two-factor solution, although an overall score of all 15 ACSS items showed the highest internal consistency. Results also showed that this overall score had good discriminant and divergent validity. It is expected that the availability of a Malay version of the ACSS will stimulate cross-cultural research on the acceptance of cosmetic surgery. Copyright © 2010 Elsevier Ltd. All rights reserved.

  16. Modelling the training effects of kinaesthetic acuity measurement in children.

    Sims, K; Morton, J


    In previous papers (Sims, Henderson, Hulme, & Morton, 1996a; Sims, Henderson, Morton, & Hulme, 1996b) we have found that the motor skills of clumsy children are capable of significant improvement following relatively brief interventions. Most remarkably, this included a 10-minute intervention while testing the kinaesthetic acuity of the children using a staircase method (Pest). In this paper, we show that Pest testing improves the kinaesthetic acuity of normal children as well. We analyse the available data on the development and improvement of motor skills and kinaesthetic acuity and derive a causal model for the underlying skills. We show that at least three independent cognitive/biological components are required to account for the data. These three components are affected differently by the various interventions that have been tried. We deduce that improvement on a general test of motor impairment can be found as a result of training in kinaesthetic acuity or through other, independent factors.

  17. Sorption isotherms modeling approach of rice-based instant soup mix stored under controlled temperature and humidity

    Yogender Singh


    Full Text Available Moisture sorption isotherms of rice-based instant soup mix at temperature range 15–45°C and relative humidity from 0.11 to 0.86 were determined using the standard gravimetric static method. The experimental sorption curves were fitted by five equations: Chung-Pfost, GAB, Henderson, Kuhn, and Oswin. The sorption isotherms of soup mix decreased with increasing temperature, exhibited type II behavior according to BET classification. The GAB, Henderson, Kuhn, and Oswin models were found to be the most suitable for describing the sorption curves. The isosteric heat of sorption of water was determined from the equilibrium data at different temperatures. It decreased as moisture content increased and was found to be a polynomial function of moisture content. The study has provided information and data useful in large-scale commercial production of soup and have great importance to combat the problem of protein-energy malnutrition in underdeveloped and developing countries.


    Daniele Penteado Rosa


    Full Text Available Drying of orange seeds representing waste products from juice processing was studied in the temperatures of 40, 50, 60 and 70 °C and drying velocities of 0.6, 1.0 and 1.4 m/s. Experimental drying kinetics of orange seeds were obtained using a convective air forced dryer. Three thin-layer models: Page model, Lewis model, and the Henderson-Pabis model and the diffusive model were used to predict the drying curves. The Henderson-Pabis and the diffusive models show the best fitting performance and statistical evaluations. Moreover, the temperature dependence on the effective diffusivity followed an Arrhenius relationship, and the activation energies ranging from 16.174 to 16.842 kJ/mol

    Whilst the benefits of sport psychology intervention during injury rehabilitation are well documented it appears that it remains underutilised by physiotherapists (Alexanders, Anderson and Henderson, 2015, Physiotherapy, 101, 95-102). A lack of education in this field for physiotherapists has been suggested as a causative factor. Preliminary studies undertaken on North American populations have shown support for sport psychology education interventions but no studies have examined physiothera...

    M. C. Gely


    Full Text Available Sorption isotherms of castor seeds were evaluated at 30, 40, 50 and 60ºC using the static gravimetric method. Sigmoid trends were observed for isotherms obtained showing a clear effect of temperature. Experimental values were adjusted using the modified isotherms of Henderson, Halsey, Oswin and Guggenheim-Anderson-de Boer (GAB. Models were compared using four statistics parameters. The results showed that Modified Henderson model adjusted adequately the experimental values in the range of temperature evaluated. The experimental values of the safe storage moisture content for castor seeds varied between 6.1 to 8.4 % (d.b. between 20 and 40ºC, showing lower values than those reported for other traditional oilseeds as sunflower or rapeseed. The sorption heats evaluated from the combination of Clapeyron equation and Modified Henderson equation varied between 3400 and 2373 kJ/kg for moisture contents between 1 and 28 % (d.b.. Through Othmer relationship the value of the ratio Lb/Lf varied between 1.01 and 1.34 (for 14.5 and 1% d.b. moisture content respectively. The values obtained showed an exponential relationship with moisture content, of the form Lb/Lf=1+0.44exp(-0.17M with a determination coefficient R² of 0.97.

  2. Evaluation of spectrum measurement devices for operational use

    Devine, R T; Gray, D W; Seagraves, D T; Olsher, R H; Johnson, J P


    Several neutron spectrometers manufactured by Bubble Technology Industries (BTI) were tested and evaluated in a variety of neutron fields. Findings and conclusions are presented for the following BTI instruments: a modification of the Rotational Spectrometer (ROSPEC) that includes a thermal and epithermal capability, the Simple Scintillation Spectrometer that is used in conjunction with the ROSPEC to extend its high-energy range, and the MICROSPEC N-Probe which is capable of providing a crude spectrum over the energy range from thermal to 18 MeV. The main objective of these measurements was to determine the accuracy of both the energy spectrum and dose equivalent information generated by these devices. In addition, the dose response of the Wide-Energy Neutron Detection Instrument (WENDI-II) was measured in all neutron fields relative to a bare sup 2 sup 5 sup 2 Cf calibration. The performance of the WENDI-II rem meter was compared to the dose information generated by the neutron spectrometers. The instruments...

  3. Changes in the nutritional quality of fast-food items marketed at restaurants, 2010 v. 2013.

    Soo, Jackie; Harris, Jennifer L; Davison, Kirsten K; Williams, David R; Roberto, Christina A


    To examine the nutritional quality of menu items promoted in four (US) fast-food restaurant chains (McDonald's, Burger King, Wendy's, Taco Bell) in 2010 and 2013. Menu items pictured on signs and menu boards were recorded at 400 fast-food restaurants across the USA. The Nutrient Profile Index (NPI) was used to calculate overall nutrition scores for items (higher scores indicate greater nutritional quality) and was dichotomized to denote healthier v. less healthy items. Changes over time in NPI scores and energy of promoted foods and beverages were analysed using linear regression. Four hundred fast-food restaurants (McDonald's, Burger King, Wendy's, Taco Bell; 100 locations per chain). NPI of fast-food items marketed at fast-food restaurants. Promoted foods and beverages on general menu boards and signs remained below the 'healthier' cut-off at both time points. On general menu boards, pictured items became modestly healthier from 2010 to 2013, increasing (mean (se)) by 3·08 (0·16) NPI score points (Prestaurants showed limited improvements in nutritional quality in 2013 v. 2010.

  4. Staying alive: rethinking deterritorialization in a post-feminist era.

    Lundberg, Anna


    In recent years, the concept 'post-feminism' and its links to neoliberal economic structures and to the extreme reinforcement of individualization as raison d'etre of Western civilization have been discussed at length by numerous distinguished scholars in feminist cultural studies and feminist philosophy. This article takes its point of departure in this discussion. Drawing on Wendy Brown, Elizabeth Grosz, Angela McRobbie, Wendy Larner, and others, the text is examining the discourse of post-feminism and neoliberalism, and its effects on overarching political scenarios, as well as on everyday life: What happens to feminist politics when the collective, both as figuration and as virtual political platform, is deemed to be something situated in the discursive outskirts? By drawing on examples form the contemporary cultural imaginaries, from popular culture, economic structures, and public debate, and by pointing out the links between the micro-perspective of our everyday living and overarching political structures, this article aims at bringing to the fore and critically discuss these issues, and the ways in which they intersect with contemporary Western feminism. The article ends with a discussion of possible points of exit or paths to follow in order to find alternatives. © 2015 John Wiley & Sons Ltd.

  5. The results of decompressive surgery and instrumented posterolateral fusion in refractory degenerative spondylolisthesis

    Behtash H


    Full Text Available "nBackground: Degenerative spondylolisthesis is a common disease of the lumbar spine especially in older ones. The disease represents a challenge to the treating physician. At present, for those patients that deteriorate clinically, there are many proposed algorithms for the surgical treatment. This before and after study was undertaken to assess the surgical results of decompression and instrumented posterolateral fusion in these patients. "nMethods: The study population consisted of 23 patients who had undergone no prior surgery for degenerative spondylolisthesis on the lumbar spine. These patients were treated by decompression, bilateral posterolateral fusion, and segmental (pedicle screw instrumentation with mean follow-up of 29 months (range, 13-73 months. Finally, The clinical results were evaluated for all patients by means of an Oswestry Disability Index (ODI version 2.1, the Henderson's functional capacity, and persistence of leg symptoms, low back pain or claudication. Mann-Whitney and Chi-Square tests were used to assess the average values and comparison, respectively. "nResults: Henderson's functional capacity at the last visit session was excellent in 14 (60.9%, good in 7 (30.4%, fair in 2 (8.7% cases. ODI decreased from 72.2% (50-88% preoperatively to 14.4% (0-54% at the latest follow-up visit. A history of leg pain or claudication was correlated significantly with the amount of decline in ODI score and Henderson's functional capacity (p<0.05. "nConclusion: In spite of limited number of our patients, decompressive surgery plus instrumented posterolateral fusion is a safe, reliable, and satisfactory procedure for treating degenerative lumbar spondylolisthesis. This procedure may be done when conservative treatment was failed and psychological problems can be ruled out.

  6. Ionisation constants of radiopharmaceuticals by HPLC

    Stylli, C.G.; Theobald, A.E.

    It has long been recognised that the pKsub(a) of drugs and radiopharmaceuticals is an important determinant of their biological distribution. In this study an HPLC method for pKa measurement has been developed for radiotracers. It has been validated with several amines and used to estimate the pKsub(a) values of some Tc-99m PnAO complexes by observing the change in chromatographic retention with change in mobile phase pH. The pKsub(a) values were estimated from the data by three methods: derivative analysis, quadratic regression, and the Henderson - Hasselbalch equation.

  12. Linear Titration Curves of Acids and Bases.

    Joseph, N R


    The Henderson-Hasselbalch equation, by a simple transformation, becomes pH - pK = pA - pB, where pA and pB are the negative logarithms of acid and base concentrations. Sigmoid titration curves then reduce to straight lines; titration curves of polyelectrolytes, to families of straight lines. The method is applied to the titration of the dipeptide glycyl aminotricarballylic acid, with four titrable groups. Results are expressed as Cartesian and d'Ocagne nomograms. The latter is of a general form applicable to polyelectrolytes of any degree of complexity.

  13. Microwave mixer technology and applications

    Henderson, Bert


    Although microwave mixers play a critical role in wireless communication and other microwave applications employing frequency conversion circuits, engineers find that most books on this subject emphasize theoretical aspects, rather than practical applications. That's about to change with the forthcoming release of Microwave Mixer Technology and Applications. Based on a review of over one thousand patents on mixers and frequency conversion, authors Bert Henderson and Edmar Camargo have written a comprehensive book for mixer designers who want solid ideas for solving their own design challenges.

  14. Judicial Understanding of the Reliability of Eyewitness Evidence: A Tale of Two Cases

    Lirieka Meintjes-van der Walt


    Full Text Available One of the most significant consequences of the use of post-conviction DNA testing in the criminal justice system has been the growing recognition that eyewitness identification testimony is simply not as reliable as it was previously considered to be. In approximately 75% of DNA exonerations in the United States, mistaken eyewitness identifications were the principal cause of wrongful convictions. Notwithstanding scientific advances regarding human memory and other factors that could influence identifications by eyewitnesses, courts have not shown eagerness in utilising such scientific knowledge in reaching legal decisions. Two cases have been chosen for discussion in this article. In S v Henderson 27 A 3d 872 (NJ 2011 the New Jersey Supreme Court was the first in State and Federal jurisdictions in the US that adopted a science-based approach to the evaluation of eyewitness evidence. The other case under discussion is S v Mdlongwa 2010 2 SACR 419 (SCA, a South African Supreme Court of Appeal judgment, where the identification of the perpetrator was based on an eyewitness account and the evidence of an expert on CCTV images. In part one of this article the research findings with regard to estimator variables that were acknowledged in S v Henderson are discussed. Part two specifically scrutinizes S v Mdlongwa to determine the extent to which psychological eyewitness research findings are recognised in South Africa as having an influence on the reliability of eyewitness evidence. In Henderson the court recognised that the legal standards governing the admissibility and use of identification evidence lagged far behind the findings of numerous studies in the social sciences. The new wave introduced by S v Henderson has not gone unnoticed in other State courts in the USA. In Massachusetts, for example, the Justices of the Supreme Judicial Court convened a study group on Eyewitness Evidence and the resulting report inter alia recommended judicial

  15. Hospital keeps cool and cuts its costs.

    Pitman, Russ


    Energy usage--particularly electricity--in hospitals is a hot topic, and the sector is under increasing pressure to reduce load and carbon emissions. The cost of 'going green' can, however, be high, and many hospitals shy away from more costly energy-efficient solutions, instead selecting cheaper options to suit the short term. One Hampshire healthcare facility, however, bucked the trend when selecting new chilled water plant, thanks to the advice and expertise of chartered consulting engineers, Henderson Green. Examining whether other hospitals should follow suit, managing director, Russ Pitman, explains 'why considering the bigger picture perspective does pay off'.

  19. NMR chemical shift and J coupling parameterization and quantum mechanical reference spectrum simulation for selected nerve agent degradation products in aqueous conditions.

    Koskela, Harri; Anđelković, Boban


    The spectral parameters of selected nerve agent degradation products relevant to the Chemical Weapons Convention, namely, ethyl methylphosphonate, isopropyl methylphosphonate, pinacolyl methylphosphonate and methylphosphonic acid, were studied in wide range of pH conditions and selected temperatures. The pH and temperature dependence of chemical shifts and J couplings was parameterized using Henderson-Hasselbalch-based functions. The obtained parameters allowed calculation of precise chemical shifts and J coupling constants in arbitrary pH conditions and typical measurement temperatures, thus facilitating quantum mechanical simulation of reference spectra in the chosen magnetic field strength for chemical verification.

  13. An empirical evaluation of classification algorithms for fault prediction in open source projects

    Arvinder Kaur


    Full Text Available Creating software with high quality has become difficult these days with the fact that size and complexity of the developed software is high. Predicting the quality of software in early phases helps to reduce testing resources. Various statistical and machine learning techniques are used for prediction of the quality of the software. In this paper, six machine learning models have been used for software quality prediction on five open source software. Varieties of metrics have been evaluated for the software including C & K, Henderson & Sellers, McCabe etc. Results show that Random Forest and Bagging produce good results while Naïve Bayes is least preferable for prediction.

  16. Magical Realism in Neil Gaiman’s Coraline

    Hosseinpour Saeede


    Full Text Available Magical realism, as a narrative mode or genre in adults’ literature, has been in vogue since its revivifying with the publication of Gabriel Garcia Marquez’s One Hundred Years of Solitude (1967. However, the depiction of the genre in children’s and juvenile literature is a new trend; the presence of its elements have been traced and proved feasibly applicable in the interpretation of recent children’s fiction such as David Almond’s Skelling (1998. In this regard, the main concern of the present article is to sift the characteristic features of magical realism within Neil Gaiman’s Coraline (2002 through the application of Wendy B. Faris’s theoretical framework of the genre therewith Tzvetan Todorov’s definition of the fantastic in order to introduce the novel as an exemplar of magical realism in the domain of children’s literature.

  18. Careers and people


    UK grants for 'world's best' students Up to 100 research students will have their fees and expenses part-funded by the UK government as part of a £2.5m scheme to attract talented students from around the world to UK universities. The Newton Scholarship programme will provide £25 000 each to 100 highly skilled candidates who wish to pursue postgraduate studies in the UK. With median annual tuition fees reaching £11 900 for overseas students on laboratory-based research courses in 2009, the new scholarships will not, however, cover the full cost of a PhD. Nevertheless, the director of the Russell Group of elite universities, Wendy Piatt, praised the scheme, calling it a "welcome initiative" in the face of "increasingly fierce global competition" for top students. The first Newton Scholars are expected to begin their studies in the autumn.

  19. Il primato della libertà politica

    Brunella Casalini


    Full Text Available Casalini ripercorre Politics out of History di Wendy Brown soffermandosi in particolare sul dialogo che Brown intrattiene con il pensiero di Marx, Nietzsche e Freud. L’accento posto sul nesso tra libertà individuale e libertà politica e sulla distinzione tra “moralismo” e “moralità” apre alla problematizzazione del nodo teoria-politica. Alla luce della crisi contemporanea della sinistra americana il ruolo del teorico è quindi quello di introdurre tratti di discontinuità in quel discorso di senso comune che la politica tende invece a cristallizzare. In conclusione, secondo Brown, questo scarto deve essere recepito anche dai Women Studies che, restando ancorati a identità statiche, rischiano di non riuscire a svolgere una necessaria «funzione omeopatica» all’interno dei regimi democratici.

    Full Text Available Este ensayo presenta dos momentos de lucha de las mujeres por los derechos a la igualdad laboral, y la igualdad en el acceso a las oportunidades de trabajo. El primero de ellos, la lucha librada por las trabajadoras de Bello en 1920; el segundo, la lucha por la adopción como ley y posterior aplicación, de la ley 581 de 2000 o ley de cuotas. Aunque la lucha femenina y feminista2 ha estado encaminada a la consecución de una serie de derechos y garantías, tal vez sea el momento de replantear el camino, es decir, diversificar las metas de los movimientos de mujeres para que los fines no estén constituidos únicamente por la consagración legal de los derechos reclamados. En este orden, la crítica de los derechos de Wendy Brown resulta sugestiva

  2. Transgressive intimacy in the fiction of Costamagna, Fernández, Jeftanovic, Maturana and Meruane

    Nan Zheng


    Full Text Available The present work, framed primarily in the discourse of intimacy, Jacques Rancière’s theory of the aesthetic regime of art and Wendy Brow's revision of Foucault's reflecctions on Neoliberalism, examines the chilean fictions of the last two decades by Alejandra Costamagna, Nona Fernández, Andrea Jeftanovic, Andrea Maturana and Lina Meruane. The literary production of these female writers disagrees with patriarchal norms and those established by the neoliberal rationality dominated by the homo oeconomicus. This article analyzes the possibility of classifying these writers as a new literary generation of the post-dictatorship, which could be more inconvenient than benefical, since it would represent a gesture which could be establishing divisions between feminine and masculine; private and public; the sublime in art and the banality of everyday life.

  3. Politics out of the History of Politics

    Diana Sartori


    Full Text Available Wendy Brown’s approach in Politics out of History is characterized by an attempt to analyze the presence of the past which can be read not only under the light of Nietzsche’s legacy, but also through a comparison with Hannah Arendt’s conception of the gap between the past and the future. Like Arendt, Brown aims to look at the present as the site of politics and freedom, even though the former conceives the break with tradition as the unavoidable starting point, while the latter assumes that that break is not fully accomplished because it was not recognized. Rather, it produces Wounded Attachments whose effect is that of limiting the possibility of left criticism. Moving from this parallel, Brown’s analysis is compared to the Italian philosophy of sexual difference, stressing their common interest in thinking freedom beyond a female identity built on a presumed common oppression.

    We present a survey of the radiation background at the Spallation Neutron Source (SNS) at Oak Ridge National Laboratory, TN, USA during routine daily operation. A broad range of detectors was used to characterize primarily the neutron and photon fields throughout the facility. These include a WENDI-2 extended range dosimeter, a thermoscientific NRD, an Arktis 4 He detector, and a standard NaI photon detector. The information gathered from the detectors was used to map out the neutron dose rates throughout the facility and also the neutron dose rate and flux profiles of several different beamlines. The survey provides detailed information useful for developing future shielding concepts at spallation neutron sources, such as the European Spallation Source (ESS), currently under construction in Lund, Sweden.

  5. Synthesis and characterization of pH sensitive carboxySNARF-1 nanoreactors

    Chen Yenchi; Ostafin, Agnes; Mizukami, Hiroshi


    A rapid response dual wavelength emission pH sensor consisting of carboxySNARF-1 nanoreactors has been synthesized and shown to provide accurate pH measurements even in complex biological media, where the unprotected pH responsive dyes have failed. The carboxySNARF-1 nanoreactor is made of a calcium phosphate shell covering phosphatidylcholine liposomes filled with the dye. Its mean diameter is 150 nm with dynamic light scattering, the shell thickness is 5-7 nm with TEM, and it contains about 10 dyes/particle. The nanoreactor's response time to pH change nearly equals that of the dye in solution. Its pH titration curves at two different wavelengths are equivalent to those of the dye in solution and fluorescence intensity ratio dependent pH analysis is possible using the modified Henderson-Hasselbalch equation. However, the pH dependent fluorescence ratios of the dye in solution in the presence of plasma and albumin are distorted, and application of the Henderson-Hasselbalch equation is not possible. We have found that the distortions may be restored using cSNARF-1 nanoreactors and the pK a of the dye in the nanoreactor then equals that in solution. These results suggest that the interference to the dye for the pH analyses with the environmental molecules may be reduced or prohibited by usage of cSNARF-1 nanoreactors.

  7. To measure ammonia and the ammonium-ion in high concentrations with sensitrodes; Messreihen mit Ammoniak- und Ammonium-Sensitroden in ungewoehnlich hohen Konzentrationsbereichen

    Brosche, P. [DBI-EWI GmbH, Freiberg (Germany)


    Ammonia up to 8 Mol/kg and the ammonium-ion up to 5 Mol/kg were investigated by sensitrodes. Sensitrodes of different manufacturers, the influence of different salts, the temperature (25 and 50 C) and ammonia in mixture with the ammonium-ion were assessed in respect of the result for measuring. The functional correlation between the pH-value and the logarithmus for the ratio of ammonium-ion to ammonia in respect of the equation from Henderson and Hasselbalch was examined. The given concentration for ammonia respectively the ammonium-ion was compared with the calculated concentration of the calibration curve. The investigated sensitrodes may be installed in the manufacturing of ammonium salts in mixture with ammonia as measuring and controlling unit. (orig.) [Deutsch] Ammoniak bis 8 mol/kg und das Ammoniumion bis 5 mol/kg wurden mittels Sensitroden untersucht.

  8. Physicochemical evaluation and hygroscopic behavior of powdered guava obtained by spray drying

    Alinne Alencar Costa dos Santos

    Full Text Available The guava is one of the most popular tropical fruits, being highly accepted all over Brazil. Many food products can be made from the fruit, such as jams, jellies, liquors and many types of juice. Given the above, the objective of this research was to characterise atomised guava pulp as to its physicochemical composition, and assess its hygroscopic behaviour by means of adsorption isotherms employing different mathematical models. The physicochemical analyses, carried out on both the whole guava pulp and on the atomised guava powder, were: moisture; pH; acidity; soluble solids and ascorbic acid, giving the following results respectively: 88.57-5.69 %; 3.76-3.88, 0.43-0.24 mg 100 g-1; 8.43 to 93.00 ºBrix and 2.77-3.79 mg 100 g-1. The adsorption isotherms were constructed adjusting the experimental data to the mathematical models of GAB, BET, Henderson and Oswin. The Henderson model presented the best fit to the atomised guava powder for all temperatures tested, presenting an error ranging from 09.93 to 12.09% and a correlation coefficient ranging from 0.9900 to 0.9934.

  9. The care dependency scale for measuring basic human needs: an international comparison.

    Dijkstra, Ate; Yönt, Gülendam Hakverdioğlu; Korhan, Esra Akin; Muszalik, Marta; Kędziora-Kornatowska, Kornelia; Suzuki, Mizue


    To report a study conducted to compare the utility of the care dependency scale across four countries. The care dependency scale provides a framework for assessing the needs of institutionalized patients for nursing care. Henderson's components of nursing care have been used to specify the variable aspects of the concept of care dependency and to develop the care dependency scale items. The study used a cross-cultural survey design. Patients were recruited from four different countries: Japan, The Netherlands, Poland and Turkey. In each of the participating countries, basic human needs were assessed by nurses using a translated version of the original Dutch care dependency scale. Psychometric properties in terms of reliability and validity of the care dependency scale have been assessed using Cronbach's alpha, Guttman's lambda-2, inter-item correlation and principal components analysis. Data were collected in 2008 and 2009. High internal consistency values were demonstrated. Principal component analysis confirmed the one-factor model reported in earlier studies. Outcomes confirm Henderson's idea that human needs are fundamental appearing in every patient-nurse relationship, independent of the patient's age, the type of care setting and/or cultural background. The psychometric characteristics of the care dependency scale make this instrument very useful for comparative research across countries. © 2012 Blackwell Publishing Ltd.

  10. Nursing and human freedom.

    Risjord, Mark


    Debates over how to conceptualize the nursing role were prominent in the nursing literature during the latter part of the twentieth century. There were, broadly, two schools of thought. Writers like Henderson and Orem used the idea of a self-care deficit to understand the nurse as doing for the patient what he or she could not do alone. Later writers found this paternalistic and emphasized the importance of the patient's free will. This essay uses the ideas of positive and negative freedom to explore the differing conceptions of autonomy which are implicit in this debate. The notion of positive freedom has often been criticized as paternalistic, and the criticisms of self-care in the nursing literature echo criticisms from political philosophy. Recent work on relational autonomy and on the relationship between autonomy and identity are used to address these objections. This essay argues for a more nuanced conception of the obligation to support autonomy that includes both positive (freedom to) and negative (freedom from) dimensions. This conception of autonomy provides a moral foundation for conceptualizing nursing in something like Henderson's terms: as involving the duty to expand the patient's capacities. The essay concludes by generalizing the lesson. Respect for autonomy on the part of any health care provider requires both respect for the patient's choices and a commitment to expand the patient's ability to actualize their choices. © 2013 John Wiley & Sons Ltd.

  11. Desorption isotherms of heavy (AZOBE, EBONY) and light heavyweight tropical woods (IROKO, SAPELLI) of Cameroon

    Nsouandélé, J. L.; Tamba, J. G.; Bonoma, B.


    This work is centered on the study of the desorption isotherms of heavy (Azobe, Ebony) and heavyweight (Iroko, Sapelli) tropical woods, which contribute in the determination of drying and storage of tropical plank woods. Desorption isotherms of tropical woods were experimentally determined under different temperatures in this study using the gravimetric method. The determination of Henderson's model isotherms parameters of desorption were obtained for temperatures of 20 °C, 30 °C, 40 °C, and 50 °C. The mean relative deviation between theoretical and experimental moisture contents was calculated and fitted well with the desorption models of tropical woods. We noticed that Henderson models fitted much better with experimental ones for 95% of relative humidity. The sigmoid shapes of results are satisfactory. Hysteresis phenomenon was observed for desorption isotherms of heavy (Azobe, Ebony) and heavyweight (Iroko, Sapelli) tropical woods. Results showed the difference between the stability and use of heavy and heavyweight tropical wood. These results help in the estimation of water content at equilibrium of tropical woods in relative humidity from experimented ones. Hygroscopic equilibrium humidity of heavy tropical woods varied between 0% and 50% while those of heavyweight varied between 0% and 25%. Therefore, these woods can be used in an opened environment; woodwork and decoration.

  12. Hygroscopic trend of lyophilized ‘mangaba’ pulp powder

    Juliana Conegero

    Full Text Available ABSTRACT Mangaba is a widely-consumed fruit in the Northeast of Brazil, which is usually exploited through extractivism. This fruit is rich in various nutrients, especially in vitamin C, with pleasant taste and aroma. The lyophilization process transforms these fruits into amorphous powders, which must be analyzed regarding their properties and hygroscopic trend. Thus, the objective of this study was to characterize and evaluate the physico-chemical properties of adsorption isotherms of the lyophilized ‘mangaba’ pulp powder, with addition of maltodextrin (DE 20. The pH, titratable acidity, soluble solids, ascorbic acid and water activity were analyzed. Regarding the isotherms, the mathematical models of GAB, BET, Oswin, and Henderson were used at temperatures of 25, 30, 35 and 40 °C. The obtained powder presented pH of 3.14, titratable acidity of 1.95 mg of citric acid 100g-1 of powder, soluble solid contents of 99 ºBrix, ascorbic acid content of 55.97 mg 100g-1 and water activity of 0.16. Henderson was the mathematical model that best fitted the data of the adsorption isotherms at the four evaluated temperatures, with average errors ranging from 5.76 to 9.70% and R2 from 0.9974 to 0.9995.

  13. Raman scattering and modulated-DSC experiments on Potassium Germanate glasses*

    Wang, N.; Novita, D.; Boolchand, P.


    We have synthesized titled glasses in the 0 modulated-DSC (MDSC) experiments. Raman lineshapes observed in the present work are quite similar to those reported by Henderson and Wang ^1. Preliminary MDSC experiments reveal glass transition temperatures, Tg(x), starting from a value of 570 C at x = 0, to decrease to 508 C near x = 0.06, and to increase thereafter almost linearly to 552 C as x increases to 0.15. On the other hand, the non-reversing enthalpy associated with Tg provides evidence of a global minimum in the 0.08 0.10 as Floppy, while those in the reversibility window as representing the Intermediate Phase^2. The space filling nature of the Intermediate Phase is, independently, corroborated by trends in molar volumes which show a broad global minimum in the 9-11% range. Identification of the three elastic phases provides a physical basis to understand the origin of the Germanate anomaly, and the electrical conductivity threshold when glasses become mechanically floppy. *Supported by NSF grant DMR 04-56472. ^1 G.S.Henderson and H.M.Wang, Eur.

  14. A Maple Program That Illustrates the Effect of pH on Peptide Charge

    Sokolik, Charles W.


    One topic covered early in an introductory biochemistry course is acid-base chemistry and the Henderson-Hasselbalch equation (buffer equation). Using this equation a biochemistry student can determine the partial charges of amino acids in a peptide chain. This is an important concept to master for a student who is learning the structure-function relationship in proteins. The program described in this paper, written for Maple V, release 3 (Waterloo Maple Software, Waterloo, ON, Canada), uses the Henderson-Hasselbalch equation to calculate the partial charges of individual amino acids and the net charge of a peptide over the pH range 0 to 14. The amino acid sequence of a peptide is entered and an animated histogram is displayed illustrating the partial charge of the amino acids over the pH range. A graph showing the net charge of the peptide from pH 0 to 14 is also given. The program has been used with success in an introductory biochemistry course as an in-class demonstration as well as for individual homework assignments. The program is available through the Web page of the Journal of Chemical Education.

  15. Exact Analytic Result of Contact Value for the Density in a Modified Poisson-Boltzmann Theory of an Electrical Double Layer.

    Lou, Ping; Lee, Jin Yong


    For a simple modified Poisson-Boltzmann (SMPB) theory, taking into account the finite ionic size, we have derived the exact analytic expression for the contact values of the difference profile of the counterion and co-ion, as well as of the sum (density) and product profiles, near a charged planar electrode that is immersed in a binary symmetric electrolyte. In the zero ionic size or dilute limit, these contact values reduce to the contact values of the Poisson-Boltzmann (PB) theory. The analytic results of the SMPB theory, for the difference, sum, and product profiles were compared with the results of the Monte-Carlo (MC) simulations [ Bhuiyan, L. B.; Outhwaite, C. W.; Henderson, D. J. Electroanal. Chem. 2007, 607, 54 ; Bhuiyan, L. B.; Henderson, D. J. Chem. Phys. 2008, 128, 117101 ], as well as of the PB theory. In general, the analytic expression of the SMPB theory gives better agreement with the MC data than the PB theory does. For the difference profile, as the electrode charge increases, the result of the PB theory departs from the MC data, but the SMPB theory still reproduces the MC data quite well, which indicates the importance of including steric effects in modeling diffuse layer properties. As for the product profile, (i) it drops to zero as the electrode charge approaches infinity; (ii) the speed of the drop increases with the ionic size, and these behaviors are in contrast with the predictions of the PB theory, where the product is identically 1.

    Francesco Sgambato


    Full Text Available Introduction: It has been 100 years since the concept of pH (1909-2009 was ‘‘invented’’ by the Danish chemist-mathematician Søren Peter Lauritz Sørensen (1868-1939 in the chemistry laboratories of the Carlsberg Brewery in Copenhagen. The anniversary provides an opportunity to examine the crucial importance in human life of acid-base balance. Materials and methods: The authors review the historical process that led to the creation of the pH scale, with citation of passages from the original work of Sørensen published 100 years ago. This is followed by a critical analysis of the debate regarding the use of logarithmstomeasure hydrogen ion concentrations based on data from scientific papers published over the past 50 years (1960-2010. Results and discussion: The authors conclude that the concept of acid-base balance can be approached and taught in a simpler, more exciting, and even pleasant fashion without using the infamous and abstruse Henderson-Hasselbalch equation. The whole rationale underlying the understanding and clinical application of this vital topic is clearly and unquestionably inherent simpler, more manageable formula introduced by Henderson (without logs, which is useful and quite adequate for use in medical education.

  17. Proposal of a theoretical model for the practical nurse

    Dolores Abril Sabater


    Full Text Available AIM: To determine which model of nursing is proposed by care professionals and the reason for their choice. METHOD: cross-sectional, descriptive study design. The main variable: Nursing Models and Theories. As secondary variables were collected: age, gender, years of work experience, nursing model of basic training, and course/s related. We used a self-elaborated, anonymous questionnaire, passed between April - May, 2006. Not random sample.RESULTS: 546 nurses were invited, answered 205. 38 % response rate. Virginia Henderson was the more selected model (33%, however, 42% left the question blank, 12% indicated that they wanted to work under the guidance of a model. They selected a specifically model: Knowledge of the model to their training, standardization in other centers, the characteristics of the model itself and identification with its philosophy. They are not decided by a model by ignorance, lack of time and usefulness. CONCLUSIONS: The model chosen mostly for their daily work was Virginia Henderson model, so that knowledge of a model is the main reason for their election. Professionals who choose not to use the model in their practice realize offers and calling for resources, besides to explain the lack of knowledge on this topic. To advance the nursing profession is necessary that nurse is thought over widely on the abstract concepts of the theory in our context.

  18. Effect of air-temperature and diet composition on the drying process of pellets for japanese abalone (Haliotis discus hannai feeding

    Antonio Vega-Gálvez


    Full Text Available The aim of this research was to study the effect of air-temperature and diet composition on the mass transfer kinetics during the drying process of pellets used for Japanese Abalone (Haliotis discus hannai feeding. In the experimental design, three temperatures were used for convective drying, as well as three different diet compositions (Diets A, B and C, in which the amount of fishmeal, spirulin, algae, fish oil and cornstarch varied. The water diffusion coefficient of the pellets was determined using the equation of Fick's second law, which resulted in values between 0.84-1.94×10-10 m²/s. The drying kinetics was modeled using Page, Modified Page, Root of time, Exponential, Logarithmic, Two-Terms, Modified Henderson-Pabis and Weibull models. In addition, two new models, referred to as 'Proposed' models 1 and 2, were used to simulate this process. According to the statistical tests applied, the models that best fitted the experimental data were Modified Henderson-Pabis, Weibull and Proposed model 2, respectively. Bifactorial analysis of variance ANOVA showed that Diet A (fishmeal 44%, spirulin 9%, fish oil 1% and cornstarch 36% presented the highest diffusion coefficient values, which were favored by the temperature increase in the drying process.

  20. The role of enzyme and substrate concentration in the evaluation of serum angiotensin converting enzyme (ACE) inhibition by enalaprilat in vitro.

    Weisser, K; Schloos, J


    The relationship between serum angiotensin converting enzyme (ACE) activity and concentration of the ACE inhibitor enalaprilat was determined in vitro in the presence of different concentrations (S = 4-200 mM) of the substrate Hip-Gly-Gly. From Henderson plots, a competitive tight-binding relationship between enalaprilat and serum ACE was found yielding a value of approximately 5 nM for serum ACE concentration (Et) and an inhibition constant (Ki) for enalaprilat of approximately 0.1 nM. A plot of reaction velocity (Vi) versus total inhibitor concentration (It) exhibited a non-parallel shift of the inhibition curve to the right with increasing S. This was reflected by apparent Hill coefficients greater than 1 when the commonly used inhibitory sigmoid concentration-effect model (Emax model) was applied to the data. Slopes greater than 1 were obviously due to discrepancies between the free inhibitor concentration (If) present in the assay and It plotted on the abscissa and could, therefore, be indicators of tight-binding conditions. Thus, the sigmoid Emax model leads to an overestimation of Ki. Therefore, a modification of the inhibitory sigmoid Emax model (called "Emax tight model") was applied, which accounts for the depletion of If by binding, refers to It and allows estimation of the parameters Et and IC50f (free concentration of inhibitor when 50% inhibition occurs) using non-linear regression analysis. This model could describe the non-symmetrical shape of the inhibition curves and the results for Ki and Et correlated very well with those derived from the Henderson plots. The latter findings confirm that the degree of ACE inhibition measured in vitro is, in fact, dependent on the concentration of substrate and enzyme present in the assay. This is of importance not only for the correct evaluation of Ki but also for the interpretation of the time course of serum ACE inhibition measured ex vivo. The non-linear model has some advantages over the linear Henderson

    Purpose: To characterize stray radiation around the target volume in scanning proton therapy and study the performance of active neutron monitors. Methods: Working Group 9 of the European Radiation Dosimetry Group (EURADOS WG9—Radiation protection in medicine) carried out a large measurement campaign at the Trento Centro di Protonterapia (Trento, Italy) in order to determine the neutron spectra near the patient using two extended-range Bonner sphere spectrometry (BSS) systems. In addition, the work focused on acknowledging the performance of different commercial active dosimetry systems when measuring neutron ambient dose equivalents, H{sup ∗}(10), at several positions inside (8 positions) and outside (3 positions) the treatment room. Detectors included three TEPCs—tissue equivalent proportional counters (Hawk type from Far West Technology, Inc.) and six rem-counters (WENDI-II, LB 6411, RadEye™ NL, a regular and an extended-range NM2B). Meanwhile, the photon component of stray radiation was deduced from the low-lineal energy transfer part of TEPC spectra or measured using a Thermo Scientific™ FH-40G survey meter. Experiments involved a water tank phantom (60 × 30 × 30 cm{sup 3}) representing the patient that was uniformly irradiated using a 3 mm spot diameter proton pencil beam with 10 cm modulation width, 19.95 cm distal beam range, and 10 × 10 cm{sup 2} field size. Results: Neutron spectrometry around the target volume showed two main components at the thermal and fast energy ranges. The study also revealed the large dependence of the energy distribution of neutrons, and consequently of out-of-field doses, on the primary beam direction (directional emission of intranuclear cascade neutrons) and energy (spectral composition of secondary neutrons). In addition, neutron mapping within the facility was conducted and showed the highest H{sup ∗}(10) value of ∼51 μSv Gy{sup −1}; this was measured at 1.15 m along the beam axis. H{sup ∗}(10) values

    R. Melnyk


    Full Text Available Mean spherical approximation (MSA, second-order Barker-Henderson (BH perturbation theory and thermodynamic perturbation theory (TPT for associating fluids in combination with BH perturbation theory are applied to the study of the structural properties and phase behaviour of the Derjaguin-Landau-Verwey-Overbeek (DLVO model of lysozyme and γ-cristalline aqueous electrolyte solutions. Predictions of the MSA for the structure factors are in good agreement with the corresponding computer simulation predictions. The agreement between theoretical results for the liquid-gas phase diagram and the corresponding results of the experiment and computer simulation is less satisfactory, with predictions of the combined BH-TPT approach being the most accurate.

  7. Intervention of the hospital midwife in the case of a pregnant women who had undergone female genital mutilation. A case study.

    Díaz-Jiménez, Désirée; Rodríguez-Villalón, Marta; Moreno-Dueñas, María Begoña

    Female genital mutilation, condemned by all UN member countries has spread throughout the world as a result of migratory flows and is practiced under the guise of a custom, tradition or culture. In Spain, it is punishable as a personal injury offence under the current penal code. A clinical case study reviewedthe main actions of the midwife in this kind of injury in a pregnant woman during labour. The data collected from the physical examination and the midwife's assessment according to the Virginia Henderson model are presented and a complete care plan developed. From the case it can be concluded that in the hospital area, midwives can and should reinforce and complete the work with these women and their families, of informing, educating and reinforcing the decision not to mutilate.

  8. Screened exchange hybrid density functional for accurate and efficient structures and interaction energies.

    Brandenburg, Jan Gerit; Caldeweyher, Eike; Grimme, Stefan


    We extend the recently introduced PBEh-3c global hybrid density functional [S. Grimme et al., J. Chem. Phys., 2015, 143, 054107] by a screened Fock exchange variant based on the Henderson-Janesko-Scuseria exchange hole model. While the excellent performance of the global hybrid is maintained for small covalently bound molecules, its performance for computed condensed phase mass densities is further improved. Most importantly, a speed up of 30 to 50% can be achieved and especially for small orbital energy gap cases, the method is numerically much more robust. The latter point is important for many applications, e.g., for metal-organic frameworks, organic semiconductors, or protein structures. This enables an accurate density functional based electronic structure calculation of a full DNA helix structure on a single core desktop computer which is presented as an example in addition to comprehensive benchmark results.

  9. Southern high latitude squat lobsters II: description of Uroptychus macquariae sp. nov. from Macquarie Ridge.

    Schnabel, Kareen E; Burghardt, Ingo; Ahyong, Shane T


    Squat lobsters have only recently been recorded from the Macquarie Ridge, which extends south between New Zealand and Antarctica. Among these, Uroptychus insignis (Henderson, 1885) was recorded for the first time outside the western Indian Ocean, exhibiting only subtle morphological differences. Reexamination of the Macquarie Ridge and Indian Ocean specimens attributed to U. insignis using morphological and molecular data revealed the Macquarie Ridge form to represent a separate species. Subtle but consistent morphological differences are evident and partial CO1 sequence data indicates that the specimens collected on Macquarie Ridge differ from those collected in the Indian Ocean by more than 7%. The Macquarie Ridge species is described herein as Uroptychus macquariae n.sp. Subtle morphological differences between the new species and U. insignis are discussed.

    Full Text Available Desorption and adsorption equilibrium moisture isotherms of Ziziphus spina-christi leaves were determined using the gravimetric-static method at 30, 40, and 50°C for water activity (aw ranging from 0.057 to 0.898. At a given aw, the results show that the moisture content decreases with increasing temperature. A hysteresis effect was observed. The experimental data of sorption were fitted by eight models (GAB, BET, Henderson-Thompson, modified-Chung Pfost, Halsey, Oswin, Peleg, and Adam and Shove. After evaluating the models according to several criteria, the Peleg and Oswin models were found to be the most suitable for describing the sorption curves. The net isosteric heats of desorption and adsorption of Ziziphus spina-christi leaves were calculated by applying the Clausius-Clapeyron equation to the sorption isotherms and an expression for predicting these thermodynamic properties was given.

  15. Perturbation theory for water with an associating reference fluid

    Marshall, Bennett D.


    The theoretical description of the thermodynamics of water is challenged by the structural transition towards tetrahedral symmetry at ambient conditions. As perturbation theories typically assume a spherically symmetric reference fluid, they are incapable of accurately describing the liquid properties of water at ambient conditions. In this paper we address this problem by introducing the concept of an associated reference perturbation theory (APT). In APT we treat the reference fluid as an associating hard sphere fluid which transitions to tetrahedral symmetry in the fully hydrogen bonded limit. We calculate this transition in a theoretically self-consistent manner without appealing to molecular simulations. This associated reference provides the reference fluid for a second order Barker-Henderson perturbative treatment of the long-range attractions. We demonstrate that this approach gives a significantly improved description of water as compared to standard perturbation theories.

  16. Effect of 60Co γ-rays irradiation on equilibrium moisture content of rice

    Yu Yong; Wang Jun; Jin Shuifeng; Teng Bin


    Experiments were carried out to study the effect of irradiation on the EMC (equilibrium moisture content) of rice. Irradiation dose was included in three widely used models for EMC, the parameters in models based on the experimental data, and correlation coefficient, mean relative error and standard error of moisture were studied for the better model. Experimental results show that gamma irradiation dose affects the values of EMC of grain at the same relative humidity and temperature of ambient. Values of the EMC decreased with increass of γ-rays irradiation dose during both adsorption and desorption process. Based on the correlation coefficient, mean relative error and standard error of moisture, the modified Chung-Pfost equation and the modified Henderson equation were found to fit the desorption and adsorption isotherms for rough rice grain in the range of experimental conditions.

  17. Nexus analysis and interaction in healthcare educational practices

    Kjær, Malene

    ABSTRACT. Internationally, student nurses' attrition after clinical practice is an increasing problem (Hamshire, Willgoss, & Wibberley, 2012; Pilegård Jensen, 2006). A better understanding of 'becoming a nurse' as situated practice in the hospital wards might help avoid pitfalls in the clinical...... practice. Thus a thorough insight into the field is necessary in order to change it. Using nexus analysis (Scollon & Scollon, 2004, 2007) as an ethnographic framework a study of the development of a professional identity among student nurses in Denmark was conducted. Scollon and Scollon’s notions...... on 'navigate' and 'engage' in the field provided a frame to combine both discourse (Edley, 2014) document (Prior, 2003) and interaction analysis (Jordan & Henderson, 1995; Sacks, 1992) in order to grasp the crucial social actors (nurses, students, patients, relatives) and their daily routinized practice...

    in the control health plan members. DID analyses indicated that the decline in overall drug use was 6% lower (P = 0.020), and the increase in plan costs was 27% higher (P = 0.002) among Florida health plan members compared with control group members. Members in a Florida Medicaid health plan with a state-mandated PDL saw declines in overall and generic drug use and an increase in drug plan costs. States considering a state-mandated PDL should take into account potential effects of decreased generic drug use and increases in prescription drug plan costs. Funding for this study was provided internally by Express Scripts Holding Company. The authors and acknowledged contributors are employees of Express Scripts Holding Company. All authors contributed to the study concept, and study design was provided by Munshi, Mager, and Henderson. Munshi and Mager collected the data, and Munshi provided the statistical analysis. Data interpretation was performed by Munshi, Mager, and Henderson. The manuscript was written by Munshi, Henderson, and Mager and revised by Munshi, Ward, Mischel, and Henderson.

  19. E-nursing documentation as a tool for quality assurance.

    Rajkovic, Vladislav; Sustersic, Olga; Rajkovic, Uros


    The article presents the results of a project with which we describe the reengineering of nursing documentation. Documentation in nursing is an efficient tool for ensuring quality health care and consequently quality patient treatment along the whole clinical path. We have taken into account the nursing process and patient treatment based on Henderson theoretical model of nursing that consists of 14 basic living activities. The model of new documentation enables tracing, transparency, selectivity, monitoring and analyses. All these factors lead to improvements of a health system as well as to improved safety of patients and members of nursing teams. Thus the documentation was developed for three health care segments: secondary and tertiary level, dispensaries and community health care. The new quality introduced to the documentation process by information and communication technology is presented by a database model and a software prototype for managing documentation.

    Full Text Available The equilibrium moisture contents of parsley leaves were measured by the gravimetric dynamic method with continuous recording of changes in sample weight. Consequently water activity values were determined. Henderson equation was found to be a good model both for moisture adsorption and desorption. Isosteric heat of sorption was defined and determined in the temperature range of 10–30 °C. Clausius-Clapeyron equation was used to calculate the isosteric heat of sorption since no dependence on temperature in the analysed range was observed. The isosteric heats of sorption (qnst were indicated graphic in the form qnst versus moisture content. Values for isosteric heat of sorption ranged from 54.41 to 46.85 kJ/mol.

  2. Aphandra natalia(Arecaceae – a little known source of piassaba fibers from the western Amazon

    Mette Kronborg


    Full Text Available Aphandra natalia(Balslev & Henderson Barfod is a multipurpose palm that is exploited both commercially and for subsistence purposes. Its fibers are important in Peruvian and Ecuadorean broom industries and support many people economically. In Brazil, it is found in the western part of Acre, where it is the main source for a local broom market. Data from fieldwork in Peru (2007 suggests that the variation in gross profit per kilogram of fiber is considerable among the different segments in the broom industry. Harvesters and distributors earn negligible amounts of money whereas manufacturers reap of the major part of the earnings. Fiber extraction appears to be sustainable in Ecuador and in some parts of Peru, whereas in other parts of Peru unsustainable harvest occurs, involving felling of entire palm trees for the harvest of fibers. The same destructive extraction method is used in Brazil, where the palm is becoming rare in its natural distribution area.

  3. Weakly infinite-dimensional spaces

    Fedorchuk, Vitalii V


    In this survey article two new classes of spaces are considered: m-C-spaces and w-m-C-spaces, m=2,3,...,∞. They are intermediate between the class of weakly infinite-dimensional spaces in the Alexandroff sense and the class of C-spaces. The classes of 2-C-spaces and w-2-C-spaces coincide with the class of weakly infinite-dimensional spaces, while the compact ∞-C-spaces are exactly the C-compact spaces of Haver. The main results of the theory of weakly infinite-dimensional spaces, including classification via transfinite Lebesgue dimensions and Luzin-Sierpinsky indices, extend to these new classes of spaces. Weak m-C-spaces are characterised by means of essential maps to Henderson's m-compacta. The existence of hereditarily m-strongly infinite-dimensional spaces is proved.

Lee et al. reported the improved Shah correlation gave us the best predictor for the condensation heat transfer data of Kim and Henderson in a subcooled and saturated water pool. They suggested the improved Shah correlation should be adopted as condensation heat transfer module in TSCON(Thermal Sizing of CONdenser) to design condensation heat exchanger in secondary passive cooling system of nuclear plant.

  8. Social and political amplification of technological hazards

    Ibitayo, Olurominiyi O.; Mushkatel, Alvin; Pijawka, K. David


    Using an industrial explosion in Henderson, Nevada, as a case study, this paper examines three main issues: the efficacy of a technological hazard event in amplifying otherwise latent issues, the extent to which the hazard event can serve as a focusing event for substantive local and state policy initiatives, and the effect of fragmentation of political authority in managing technological hazards. The findings indicate that the explosion amplified several public safety issues and galvanized the public into pressing for major policy initiatives. However, notwithstanding the amplification of several otherwise latent issues, and the flurry of activities by the state and local governments, the hazard event did not seem to be an effective focusing event or trigger mechanism for substantive state and local policy initiatives. In addition, the study provides evidence of the need for a stronger nexus between political authority, land-use planning and technological hazard management

    Mohd Yusof Othman; Ahmad Fudholi; Kamaruzzaman Sopian; Mohd Hafidz Ruslan; Muhammad Yahya


    A solar drying system suitable for agricultural and marine products have been designed, constructed and evaluated under Malaysia climatic conditions. The solar drying system has been constructed and evaluated for the drying of seaweed Gracilaria changii. The initial and final moisture content of seaweed are 95 % (wet basis) and 10 % (product basis), respectively. The drying time was about 7 hours at average solar radiation of 593 W/ m 2 and air flow rate of 0.0613 kg/ s. Three different thin-layer drying models were compared with experimental data, during the drying of seaweed using the solar drying system at average temperature and humidity of about 50 degree Celsius and 20 %, respectively. The one with highest R2 and lowest MBE and RMSE was selected to better estimate the drying curves. The study showed that the Page model was better fit to drying seaweed compared to the other models (Newton model, and Henderson and Pabis model). (author)

  10. Extreme metabolic alkalosis in intensive care.

    Tripathy, Swagata


    Metabolic alkalosis is a commonly seen imbalance in the intensive care unit (ICU). Extreme metabolic alkalemia, however, is less common. A pH greater than 7.65 may carry a high risk of mortality (up to 80%). We discuss the entity of life threatening metabolic alkalemia by means of two illustrative cases - both with a pH greater than 7.65 on presentation. The cause, modalities of managing and complications of this condition is discussed from the point of view of both the traditional method of Henderson and Hasselbalch and the mathematical model based on physiochemical model described by Stewart. Special mention to the pitfalls in managing patients of metabolic alkalosis with concomitant renal compromise is made.

  11. Drying kinetics of atemoya pulp

    Plúvia O. Galdino

    Full Text Available ABSTRACT This study was conducted in order to obtain drying curves of whole atemoya pulp through the foam-mat drying method. The suspension was prepared with whole atemoya pulp mixed with 2% of Emustab® and 2% of Super Liga Neutra® with mixing time of 20 min, and dried in a forced-air oven at different temperatures (60; 70 and 80 °C and thicknesses of the foam layer (0.5, 1.0 and 1.5 cm. The drying rate curves were plotted against the water content ratio and the semi-theoretical models of Henderson & Pabis, Page and Midilli were used. All tested models showed coefficient of determination (R2 above 0.993, and the Midilli model showed the best fit for all conditions. Drying curves were affected by temperature and layer thickness.

  12. The molybdenum-technetium solar neutrino experiment

    Schroeder, N.C.; Wolfsberg, K.; Rokop, D.J.


    The authors are attempting to measure the time-averaged 8 B solar-neutrino flux over 10 Myr by measuring 98 Tc produced through the 98 Mo( nu ,e - ) reaction in a deeply buried molybdenum deposit. This will test the prediction of periodic mixing of the Sun's core over long time intervals. To separate technetium from 10,000-ton quantities of Henderson ore, the authors have taken advantage of the commercial processing of molybdenite. Technetium, volatilized during roasting of molybdenite to MoO 3 , was scrubbed from the gas stream and collected on anion exchange columns. After sample reduction and chemical separation and purification they measured technetium, as TcO 4 - , using negative thermal ionization mass spectrometry. Measurement of 99 Tc in spiked and 98 Tc in unspiked fractions from one sample gives an apparent solar neutrino production rate of 95.8 SNU. However, roaster memory probably invalidates this result

  13. Field measurements, simulation modeling and development of analysis for moisture stressed corn and soybeans, 1982 studies

    Blad, B. L.; Norman, J. M.; Gardner, B. R.


    The experimental design, data acquisition and analysis procedures for agronomic and reflectance data acquired over corn and soybeans at the Sandhills Agricultural Laboratory of the University of Nebraska are described. The following conclusions were reached: (1) predictive leaf area estimation models can be defined which appear valid over a wide range of soils; (2) relative grain yield estimates over moisture stressed corn were improved by combining reflectance and thermal data; (3) corn phenology estimates using the model of Badhwar and Henderson (1981) exhibited systematic bias but were reasonably accurate; (4) canopy reflectance can be modelled to within approximately 10% of measured values; and (5) soybean pubescence significantly affects canopy reflectance, energy balance and water use relationships.

  16. On the contact values of the density profiles in an electric double layer using density functional theory

    L.B. Bhuiyan


    Full Text Available A recently proposed, local second contact value theorem [Henderson D., Boda D., J. Electroanal. Chem., 2005, Vol. 582, 16] for the charge profile of an electric double layer is used in conjunction with existing Monte Carlo data from the literature to assess the contact behavior of the electrode-ion distributions predicted by the density functional theory. The results for the contact values of the co- and counterion distributions and their product are obtained for the symmetric valency, restricted primitive model planar double layer for a range of electrolyte concentrations and temperatures. Overall the theoretical results satisfy the second contact value theorem reasonably well the agreement with the simulations being semi-quantitative or better. The product of the co- and counterion contact values as a function of the electrode surface charge density is qualitative with the simulations with increasing deviations at higher concentrations.

  17. Application of a recently proposed test to the hypernettedchain approximation for the electric double layer



    Full Text Available Bhuiyan, Outhwaite, and Henderson, J. Electroanal. Chem., 2007, 607, 54, have studied the electric double layer formed by a symmetric electrolyte in the restricted primitive model and suggested that an examination of the product of the coion and counter ion profiles, normalized to the one when the distance of an ion from the electrode is large, is an interesting and useful test of a theory. This product is identically one in the Poisson-Boltzmann theory but simulation results show that, at contact, this product can be greater or smaller than one at small electrode charge but always seems to tend to zero at large electrode charge. In this study we report the results of the hypernetted chain approximation (HNC/MSA version for this product and find that, at contact, for this theory this product is always greater than the one at small electrode charge but tends to zero at large electrode charge.

  18. Mathematical modelling of the thin layer solar drying of banana, mango and cassava

    Koua, Kamenan Blaise; Fassinou, Wanignon Ferdinand; Toure, Siaka [Laboratoire d' Energie Solaire, Universite de Cocody- Abidjan, 22 BP 582 Abidjan 22 (Ivory Coast); Gbaha, Prosper [Laboratoire d' Energie Nouvelle et Renouvelable, Institut National Polytechnique, Felix HOUPHOUET - BOIGNY de Yamoussoukro (Ivory Coast)


    The main objectives of this paper are firstly to investigate the behaviour of the thin layer drying of plantain banana, mango and cassava experimentally in a direct solar dryer and secondly to perform mathematical modelling by using thin layer drying models encountered in literature. The variation of the moisture content of the products studied and principal drying parameters are analysed. Seven statistical models, which are empirical or semi-empirical, are tested to validate the experimental data. A non-linear regression analysis using a statistical computer program is used to evaluate the constants of the models. The Henderson and Pabis drying model is found to be the most suitable for describing the solar drying curves of plantain banana, mango and cassava. The drying data of these products have been analysed to obtain the values of the effective diffusivity during the falling drying rate phase. (author)

  19. Estimation of the soil-water partition coefficient normalized to organic carbon for ionizable organic chemicals

    Franco, Antonio; Trapp, Stefan


    The sorption of organic electrolytes to soil was investigated. A dataset consisting of 164 electrolytes, composed of 93 acids, 65 bases, and six amphoters, was collected from literature and databases. The partition coefficient log KOW of the neutral molecule and the dissociation constant pKa were...... calculated by the software ACD/Labs®. The Henderson-Hasselbalch equation was applied to calculate dissociation. Regressions were developed to predict separately for the neutral and the ionic molecule species the distribution coefficient (Kd) normalized to organic carbon (KOC) from log KOW and pKa. The log...... KOC of strong acids (pKa correlated to these parameters. The regressions derived for weak acids and bases (undissociated at environmental pH) were similar. The highest sorption was found for strong bases (pKa > 7.5), probably due to electrical interactions. Nonetheless, their log KOC...

  3. Smart release of doxorubicin loaded on polyetheretherketone (PEEK) surface with 3D porous structure.

    Ouyang, Liping; Sun, Zhenjie; Wang, Donghui; Qiao, Yuqin; Zhu, Hongqin; Ma, Xiaohan; Liu, Xuanyong


    It is important to fabricate an implant possessing environment sensitive drug delivery. In this work, the construction of 3D porous structure on polyetheretherketone (PEEK) surface and pH sensitive polymer, chitosan, was introduced. The smart release of doxorubicin can be realized on the 3D porous surface of PEEK loading chitosan. We give a feasible explanation for the effect of chitosan on smart drug release according to Henderson-Hasselbalch equation. Furthermore, the intracellular drug content of the cell cultured on the samples with highest chitosan is significantly higher at pH 4.0, whereas lower at pH 7.4 than other samples. The smart release of doxorubicin via modification with chitosan onto 3D porous PEEK surface paves the way for the application of PEEK in drug loading platform for recovering bone defect caused by malignant bone tumor.

  4. Long range personalized cancer treatment strategies incorporating evolutionary dynamics.

    Yeang, Chen-Hsiang; Beckman, Robert A


    approaches, by far the majority show an advantage of multi-step or ALTO over single-step optimization. ALTO-SMO delivers cure rates superior or equal to those of single- or multi-step optimization, in 2 and 3 drug cases respectively. In selected virtual patients incurable by dynamic precision medicine using single-step optimization, analogous strategies that "think ahead" can deliver long-term survival and cure without any disadvantage for non-responders. When therapies require dose reduction in combination (due to toxicity), optimal strategies feature complex patterns involving rapidly interleaved pulses of combinations and high dose monotherapy.

  6. The real bounty: marine biodiversity in the Pitcairn Islands.

    Alan M Friedlander

    Full Text Available In 2012 we conducted an integrated ecological assessment of the marine environment of the Pitcairn Islands, which are four of the most remote islands in the world. The islands and atolls (Ducie, Henderson, Oeno, and Pitcairn are situated in the central South Pacific, halfway between New Zealand and South America. We surveyed algae, corals, mobile invertebrates, and fishes at 97 sites between 5 and 30 m depth, and found 51 new records for algae, 23 for corals, and 15 for fishes. The structure of the ecological communities was correlated with age, isolation, and geomorphology of the four islands. Coral and algal assemblages were significantly different among islands with Ducie having the highest coral cover (56% and Pitcairn dominated by erect macroalgae (42%. Fish biomass was dominated by top predators at Ducie (62% of total fish biomass and at Henderson (35%. Herbivorous fishes dominated at Pitcairn, while Oeno showed a balanced fish trophic structure. We found high levels of regional endemism in the fish assemblages across the islands (45%, with the highest level observed at Ducie (56% by number. We conducted the first surveys of the deep habitats around the Pitcairn Islands using drop-cameras at 21 sites from depths of 78 to 1,585 m. We observed 57 fish species from the drop-cams, including rare species such as the false catshark (Pseudotriakis microdon and several new undescribed species. In addition, we made observations of typically shallow reef sharks and other reef fishes at depths down to 300 m. Our findings highlight the uniqueness and high biodiversity value of the Pitcairn Islands as one of the least impacted in the Pacific, and suggest the need for immediate protection.

  7. The Bacterial Community Structure and Dynamics of Carbon and Nitrogen when Maize (Zea mays L.) and Its Neutral Detergent Fibre Were Added to Soil from Zimbabwe with Contrasting Management Practices.

    De la Cruz-Barrón, Magali; Cruz-Mendoza, Alejandra; Navarro-Noya, Yendi E; Ruiz-Valdiviezo, Victor M; Ortíz-Gutiérrez, Daniel; Ramírez-Villanueva, Daniel A; Luna-Guido, Marco; Thierfelder, Cristian; Wall, Patrick C; Verhulst, Nele; Govaerts, Bram; Dendooven, Luc


    Water infiltration, soil carbon content, aggregate stability and yields increased in conservation agriculture practices compared to conventionally ploughed control treatments at the Henderson research station near Mazowe (Zimbabwe). How these changes in soil characteristics affect the bacterial community structure and the bacteria involved in the degradation of applied organic material remains unanswered. Soil was sampled from three agricultural systems at Henderson, i.e. (1) conventional mouldboard ploughing with continuous maize (conventional tillage), (2) direct seeding with a Fitarelli jab planter and continuous maize (direct seeding with continuous maize) and (3) direct seeding with a Fitarelli jab planter with rotation of maize sunn hemp (direct seeding with crop rotation). Soil was amended with young maize plants or their neutral detergent fibre (NDF) and incubated aerobically for 56 days, while C and N mineralization and the bacterial community structure were monitored. Bacillus (Bacillales), Micrococcaceae (Actinomycetales) and phylotypes belonging to the Pseudomonadales were first degraders of the applied maize plants. At day 3, Streptomyces (Actinomycetales), Chitinophagaceae ([Saprospirales]) and Dyella (Xanthomonadales) participated in the degradation of the applied maize and at day 7 Oxalobacteraceae (Burkholderiales). Phylotypes belonging to Halomonas (Oceanospirillales) were the first degraders of NDF and were replaced by Phenylobacterium (Caulobacterales) and phylotypes belonging to Pseudomonadales at day 3. Afterwards, similar bacterial groups were favoured by application of NDF as they were by the application of maize plants, but there were also clear differences. Phylotypes belonging to the Micrococcaceae and Bacillus did not participate in the degradation of NDF or its metabolic products, while phylotypes belonging to the Acidobacteriaceae participated in the degradation of NDF but not in that of maize plants. It was found that agricultural

  8. A Guide to Laser Safety

    Davies, W M


    In one of the few volumes dedicated to laser safety to appear since the 'bible' of Sliney and Wolbarsht, Roy Henderson sets out to provide the reader with a practical account of both the philosophy and practice across contemporary application of lasers. The book is split into three sections. The first section is essentially a non-mathematical review of lasers, optical hazards and laser safety. It is intended as an easily digestible introduction to the subject, conveying the primary concepts of laser safety without the camouflage of equations. This piece of text is manifestly readable by all who have interest in the topic. The second section introduces more meat onto the bones introduced in the first section and some of the practical mathematics necessary to determine optical irradiance in simple laser beams. The book is not intended as a scientific treatise and rigorous treatment of laser physics is left (for the better) to other texts. Laser hazard assessment and safety management are covered in sufficient detail to allow the reader to understand what precautions are necessary to mitigate the risks of laser use. The final section takes a brief look at laser safety in a number of specific industrial applications. These include industrial processing, medicine, telecommunications and entertainment. These should be taken in the context of the second section and are not stand-alone text. With few typographical errors, and packed with practical hints, this book serves as an excellent text for any educational course on laser safety and provides a quick and easy reference for laser safety officers.

  9. Subsurface microbial diversity in deep-granitic-fracture water in Colorado

    Sahl, J.W.; Schmidt, R.; Swanner, E.D.; Mandernack, K.W.; Templeton, A.S.; Kieft, Thomas L.; Smith, R.L.; Sanford, W.E.; Callaghan, R.L.; Mitton, J.B.; Spear, J.R.


    A microbial community analysis using 16S rRNA gene sequencing was performed on borehole water and a granite rock core from Henderson Mine, a >1,000-meter-deep molybdenum mine near Empire, CO. Chemical analysis of borehole water at two separate depths (1,044 m and 1,004 m below the mine entrance) suggests that a sharp chemical gradient exists, likely from the mixing of two distinct subsurface fluids, one metal rich and one relatively dilute; this has created unique niches for microorganisms. The microbial community analyzed from filtered, oxic borehole water indicated an abundance of sequences from iron-oxidizing bacteria (Gallionella spp.) and was compared to the community from the same borehole after 2 weeks of being plugged with an expandable packer. Statistical analyses with UniFrac revealed a significant shift in community structure following the addition of the packer. Phospholipid fatty acid (PLFA) analysis suggested that Nitrosomonadales dominated the oxic borehole, while PLFAs indicative of anaerobic bacteria were most abundant in the samples from the plugged borehole. Microbial sequences were represented primarily by Firmicutes, Proteobacteria, and a lineage of sequences which did not group with any identified bacterial division; phylogenetic analyses confirmed the presence of a novel candidate division. This "Henderson candidate division" dominated the clone libraries from the dilute anoxic fluids. Sequences obtained from the granitic rock core (1,740 m below the surface) were represented by the divisions Proteobacteria (primarily the family Ralstoniaceae) and Firmicutes. Sequences grouping within Ralstoniaceae were also found in the clone libraries from metal-rich fluids yet were absent in more dilute fluids. Lineage-specific comparisons, combined with phylogenetic statistical analyses, show that geochemical variance has an important effect on microbial community structure in deep, subsurface systems.

    Full Text Available Este trabalho teve como objetivo determinar as curvas de dessorção das sementes de milho-doce (Zea mays L., cultivares Superdoce e Doce Cristal, e ajustar diferentes modelos matemáticos aos dados obtidos. As sementes das duas cultivares foram submetidas à dessorção em diversos níveis de temperatura (30, 40, 50 e 60°C, combinados com diferentes umidades relativas do ar (30, 40, 50 e 60%, até atingirem a umidade de equilíbrio. Os seguintes modelos matemáticos foram ajustados por análise de regressão: Henderson-Thompson, Chung-Pfost, Copace, Sigma-Copace, Sabbah e Smith. As sementes das duas cultivares apresentaram umidades de equilíbrio higroscópico semelhantes. Os valores da variância explicada e do desvio-padrão, bem como a distribuição dos resíduos, das duas cultivares, indicam que as equações de Chung-Pfost, Sabbah e Smith foram as que melhor se ajustaram aos dados experimentais, com pequena superioridade da primeira.This work had the goal to determine the desorption curves of seeds of sweet corn cultivars Superdoce and Doce Cristal, and to adjust mathematical models to obtained data. Corn seeds were submitted to desorption under different temperature conditions (30, 40, 50 and 60°C, associated with different relative humidity (30, 40, 50 and 60% until reaching the equilibrium humidity. The following models of regression analysis were adjusted to the experimental data: Henderson-Thompson, Chung-Pfost, Copace, Sigma-Copace, Sabbah and Smith. Seeds of both cultivars showed similar hygroscopic equilibrium. For both cultivars, the equations of Chung-Pfost, Sabbah and Smith, showed the best adjustments to the experimental data, with slight superiority of the first one.

    Míriam D. Hubinger


    Full Text Available O presente trabalho teve como objetivo a obtenção de isotermas de dessorção de filés de bonito (Sarda sarda, previamente salgados a vácuo e defumados com fumaça líquida. As isotermas foram obtidas a quatro temperaturas (5, 25, 40 e 60 ºC em condições de dessorção, através do método gravimétrico estático, com soluções salinas saturadas. Os dados experimentais foram ajustados a quatro modelos da literatura (BET linearizado, GAB, Henderson e Oswin modificado. Os resultados mostraram que as isotermas tomaram forma sigmoidal de tipo II e que o modelo de Guggenheim-Anderson-deBoer (GAB foi aceitável para modelar os dados experimentais. O calor isostérico de dessorção, um parâmetro necessário para simular e projetar adequadamente o secador, também foi calculado e pode ser representado através de um modelo matemático simples, em função da umidade de equilíbrio.The main objetive of this work was to obtain the desorption isotherms of Atlantic bonito (Sarda sarda fillets, previously subjected to an immersion impregnation process with NaCl solutions and smoked in liquid smoke. The isotherms were obtained at four temperatures (5, 25, 40 and 60 ºC, using the static method with saturated salt solutions. The experimental data were fitted to four models (linearized BET, GAB, Henderson and modified Oswin. The results showed that a type II sigmoidal isotherm, with GAB equation, gave the best fit. The isosteric heat of desorption was also calculated and a simple empirical equation has been proposed to represent this heat, as a function of equilibrium moisture content.

  12. Hazard personality profiles and individual differences

    Barnett, J.; Breakwell, G.M.


    Full text of publication follows: the dominance of the 'psychometric paradigm' and the consequent emphasis on identifying the qualities related to a hazard's perceived risk has resulted in little attention being given to individual variations in the acceptance of such 'personality profiles' of hazards. Attempts to locate sources of variability have largely focused on social, cultural and institutional factors (Turner and Wynne, 1992; Sjoeberg, 1995). Less attention has been paid to the role of intra-individual differences (Myers, Henderson-King, and Henderson-King, 1997). To address this, a questionnaire study (n = 172) explored the relationships between anxiety, experience and risk perceptions in relation to 16 risk activities. Different patterns of relationships for voluntary and involuntary activities were expected. Measures of experience included assessments of impact and outcome valence as well as frequency. Proclivity for, and likelihood of, future risk experiences were also assessed. The results revealed a number of relationships between individual difference variables and risk perceptions relating to the voluntariness of the activities. For involuntary risk activities, there were associations between the experience variables and risk ratings, e.g. previous experience of positive outcomes of involuntary risk activities is associated with perceptions of them affecting few people, with not being fatal and with known risk levels. This would suggest that taking into account people's previous experience of risks is likely to affect reactions to, and mediate the effectiveness of risk communications relating to involuntary risk activities. In contrast for voluntary activities it is the two 'future' oriented variables that are associated with risk perceptions. The relationship between anxiety and risk perceptions also varied in relation to the voluntariness of risk activities.

  13. Variation of molybdenum isotopes in molybdenite from porphyry and vein Mo deposits in the Gangdese metallogenic belt, Tibetan plateau and its implications

    Wang, Yong; Zhou, Lian; Gao, Shan; Li, Jian-Wei; Hu, Zhi-Fang; Yang, Lu; Hu, Zhao-Chu


    We present Mo isotopic ratios of molybdenite from five porphyry molybdenum deposits (Chagele, Sharang, Jiru, Qulong, and Zhuonuo) and one quartz-molybdenite vein-type deposit (Jigongcun) along the Gangdese metallogenic belt in the Tibetan Plateau. These deposits represent a sequence of consecutive events of the India-Asia collision at different periods. Additional molybdenite samples from the Henderson Mo deposit (USA), the oceanic subduction-related El Teniente (Chile), and Bingham (USA) porphyry Cu-(Mo) deposits were analyzed for better understanding the controls on the Mo isotope systematics of molybdenite. The results show that molybdenite from Sharang, Jiru, Qulong, and Zhuonuo deposits have similar δ97Mo (˜0 ‰), in agreement with the values of the Henderson Mo deposit (-0.10 ‰). In contrast, samples from the Changle and Jigongcun deposit have δ97Mo of 0.85 ‰ to 0.88 ‰ and -0.48 %, respectively. Molybdenite from the El Teniente and Bingham deposits yields intermediate δ97Mo of 0.27 and 0.46 ‰, respectively. The Mo isotopes, combined with Nd isotope data of the ore-bearing porphyries, indicate that source of the ore-related magmas has fundamental effects on the Mo isotopic compositions of molybdenite. Our study indicates that molybdenite related to crustal-, and mantle-derived magmas has positive or negative δ97Mo values, respectively, whereas molybdenite from porphyries formed by crust-mantle mixing has δ97Mo close to 0 ‰. It is concluded that the Mo isotope composition in the porphyry system is a huge source signature, without relation to the tectonic setting under which the porphyry deposits formed.

Two sampling methods were used. Henderson and Sundaresan¹ and an adaptation of the first and the results were later compared. An analysis was carried out to discriminate those children who had completed their vaccinations from those who had failed to do so, based on social indicators such as education of the parents and number of residents and children in each household. Part of the study focused on the principal motives given by the mother for not having vaccinated their children.

  16. From documents to datasets: A MediaWiki-based method of annotating and extracting species observations in century-old field notebooks.

    Thomer, Andrea; Vaidya, Gaurav; Guralnick, Robert; Bloom, David; Russell, Laura


    Part diary, part scientific record, biological field notebooks often contain details necessary to understanding the location and environmental conditions existent during collecting events. Despite their clear value for (and recent use in) global change studies, the text-mining outputs from field notebooks have been idiosyncratic to specific research projects, and impossible to discover or re-use. Best practices and workflows for digitization, transcription, extraction, and integration with other sources are nascent or non-existent. In this paper, we demonstrate a workflow to generate structured outputs while also maintaining links to the original texts. The first step in this workflow was to place already digitized and transcribed field notebooks from the University of Colorado Museum of Natural History founder, Junius Henderson, on Wikisource, an open text transcription platform. Next, we created Wikisource templates to document places, dates, and taxa to facilitate annotation and wiki-linking. We then requested help from the public, through social media tools, to take advantage of volunteer efforts and energy. After three notebooks were fully annotated, content was converted into XML and annotations were extracted and cross-walked into Darwin Core compliant record sets. Finally, these recordsets were vetted, to provide valid taxon names, via a process we call "taxonomic referencing." The result is identification and mobilization of 1,068 observations from three of Henderson's thirteen notebooks and a publishable Darwin Core record set for use in other analyses. Although challenges remain, this work demonstrates a feasible approach to unlock observations from field notebooks that enhances their discovery and interoperability without losing the narrative context from which those observations are drawn."Compose your notes as if you were writing a letter to someone a century in the future."Perrine and Patton (2011).

    Moss, W C; King, M J


    Lawrence Livermore National Laboratory [LLNL] was tasked to compare the impact response of NFL helmet pad systems and U.S. Army pad systems compatible with an Advanced Combat Helmet [ACH] at impact velocities up to 20 ft/s. This was a one-year study funded by the U.S. Army and JIEDDO. The Army/JIEDDO point of contact is COL R. Todd Dombroski, DO, JIEDDO Surgeon. LLNL was chosen by committee to perform the research based on prior published computational studies of the mechanical response of helmets and skulls to blast. Our collaborators include the U.S. Army Aeromedical Research Laboratory [USAARL] (a DoD laboratory responsible for impact testing helmets), Team Wendy and Oregon Aero (current and former ACH pad manufacturers), Riddell and Xenith (NFL pad manufacturers), and d3o (general purpose sports pad manufacturer). The manufacturer-supplied pad systems that were studied are shown in the figure below. The first two are the Army systems, which are bilayer foam pads with both hard and soft foam and a water-resistant airtight wrapper (Team Wendy) or a water-resistant airtight coating (Oregon Aero). The next two are NFL pad systems. The Xenith system consists of a thin foam pad and a hollow air-filled cylinder that elastically buckles under load. The Riddell system is a bilayer foam pad that is encased in an inflatable airbag with relief channels to neighboring pads in the helmet. The inflatable airbag is for comfort and provides no enhancement to impact mitigation. The d3o system consists of a rate-sensitive homogeneous dense foam. LLNL performed experiments to characterize the material properties of the individual foam materials and the response of the complete pad systems, to obtain parameters needed for the simulations. LLNL also performed X-ray CT scans of an ACH helmet shell that were used to construct a geometrically accurate computational model of the helmet. Two complementary sets of simulations were performed. The first set of simulations reproduced the

  19. Spatial Montage and Multimedia Ethnography: Using Computers to Visualise Aspects of Migration and Social Division Among a Displaced Community

    Judith Aston


    Full Text Available This paper discusses how computer-based techniques of spatial montage can be used to visualise aspects of migration and social division among a displaced community. It is based on an ongoing collaboration between the author and the anthropologist, Wendy JAMES. The work is based on a substantial archive of ethnographic photographs, audio, cine and video recordings collected by JAMES in the Sudan/Ethiopian borderlands over four decades. Initially recording the way of life of several minority peoples, she was later able to follow their fortunes during the repeated war displacements and separations they suffered from the 1980s onwards. The recordings document work rhythms, dance, song and storytelling, music and other sensory rich performances alongside spoken memories of past events. The research is developing spatial montage techniques to draw comparisons across time, between multiple points of view, and between recordings of events and spoken memories of these events. It is argued that these techniques can be used to facilitate direct engagement with ethnographic recordings, creating multimedia experiences which can flexibly integrate fieldwork data into academic discourse. In so doing it is proposed that these techniques offer new tools to enhance the analysis and understanding of issues relating to migration and social division. URN: urn:nbn:de:0114-fqs1002361

The fourth edition of the DSM had failed to adequately capture a cohort of children, adolescents, and adults who are unable to meet appropriate nutritional and/or energy needs, for reasons other than drive for thinness, leading to significant medical and/or psychological sequelae. With the introduction of ARFID, researchers are now starting to better understand the presentation, clinical characteristics, and complexities of this disorder. This article outlines the diagnostic criteria for ARFID with specific focus on children and youth. A case example of a patient with ARFID, factors that differentiate ARFID from picky eating, and the estimated prevalence in pediatric populations are discussed, as well as clinical and treatment challenges that impact health care providers providing treatment for patients.

  1. Consumers' estimation of calorie content at fast food restaurants: cross sectional observational study.

    Block, Jason P; Condon, Suzanne K; Kleinman, Ken; Mullen, Jewel; Linakis, Stephanie; Rifas-Shiman, Sheryl; Gillman, Matthew W


    To investigate estimation of calorie (energy) content of meals from fast food restaurants in adults, adolescents, and school age children. Cross sectional study of repeated visits to fast food restaurant chains. 89 fast food restaurants in four cities in New England, United States: McDonald's, Burger King, Subway, Wendy's, KFC, Dunkin' Donuts. 1877 adults and 330 school age children visiting restaurants at dinnertime (evening meal) in 2010 and 2011; 1178 adolescents visiting restaurants after school or at lunchtime in 2010 and 2011. Estimated calorie content of purchased meals. Among adults, adolescents, and school age children, the mean actual calorie content of meals was 836 calories (SD 465), 756 calories (SD 455), and 733 calories (SD 359), respectively. A calorie is equivalent to 4.18 kJ. Compared with the actual figures, participants underestimated calorie content by means of 175 calories (95% confidence interval 145 to 205), 259 calories (227 to 291), and 175 calories (108 to 242), respectively. In multivariable linear regression models, underestimation of calorie content increased substantially as the actual meal calorie content increased. Adults and adolescents eating at Subway estimated 20% and 25% lower calorie content than McDonald's diners (relative change 0.80, 95% confidence interval 0.66 to 0.96; 0.75, 0.57 to 0.99). People eating at fast food restaurants underestimate the calorie content of meals, especially large meals. Education of consumers through calorie menu labeling and other outreach efforts might reduce the large degree of underestimation.

  2. An observational study of consumer use of fast-food restaurant drive-through lanes: implications for menu labelling policy.

    Roberto, Christina A; Hoffnagle, Elena; Bragg, Marie A; Brownell, Kelly D


    Some versions of restaurant menu labelling legislation do not require energy information to be posted on menus for drive-through lanes. The present study was designed to quantify the number of customers who purchase fast food through drive-in windows as a means of informing legislative labelling efforts. This was an observational study. The study took place at two McDonald's and Burger King restaurants, and single Dairy Queen, Kentucky Fried Chicken, Taco Bell and Wendy's restaurants. The number of customers entering the chain restaurants and purchasing food via the drive-through lane were recorded. A total of 3549 patrons were observed. The percentage of customers who made their purchases at drive-throughs was fifty-seven. The overall average (57 %) is likely a conservative estimate because some fast-food restaurants have late-night hours when only the drive-throughs are open. Since nearly six in ten customers purchase food via the drive-through lanes, menu labelling legislation should mandate the inclusion of menu labels on drive-through menu boards to maximise the impact of this public health intervention.

  3. Seven Possible Cave Skylights on Mars


    [figure removed for brevity, see original site] Figure 1 Seven very dark holes on the north slope of a Martian volcano have been proposed as possible cave skylights, based on day-night temperature patterns suggesting they are openings to subsurface spaces. These six excerpts of images taken in visible-wavelength light by the Thermal Emission Imaging System camera on NASA's Mars Odyssey orbiter show the seven openings. Solar illumination comes from the left in each frame. The volcano is Arsia Mons, at 9 degrees south latitude, 239 degrees east longitude. The features have been given informal names to aid comparative discussion (see figure 1). They range in diameter from about 100 meters (328 feet) to about 225 meters (738 feet). The candidate cave skylights are (A) 'Dena,' (B) 'Chloe,' (C) 'Wendy,' (D) 'Annie,' (E) 'Abby' (left) and 'Nikki,' and (F) 'Jeanne.' Arrows signify north and the direction of illumination. Mars Odyssey is managed by NASA's Jet Propulsion Laboratory, a division of the California Institute of Technology, Pasadena, for NASA's Science Mission Directorate, Washington. Lockheed Martin Space Systems, Denver, is the prime contractor for the project and built the spacecraft. The orbiter's Thermal Emission Imaging System was developed by Arizona State University, Tempe, in collaboration with Raytheon Santa Barbara Remote Sensing, Santa Barbara, Calif., and is operated by Arizona State University.

  4. Magical Realism in Ahmad Sa'dawiy's Frankenstein fi Bagdad

    Mahmudah Mahmudah


    Full Text Available This article discusses the use of magic realism as a literary device in the Iraqi novel Frankenstein fī Bagdād written by Aḥmad Sa‘dāwiy. The novel is set in the period of inter-ethnic conflict which arose after the American invasion of 2003. Hādī, the main character of the novel, ‘creates a monster’ namely Syismah from the corpses of the many bomb victims in Baghdad. The writer combines setting of the novel with belief of the Iraq people, horoscope practice, and magic, in mystical and illogical atmosphere. Given its magic realist qualities, the analysis draws on the approach of Wendy B. Faris. The article identifies five key elements from magic realism present in the novel, and discusses the relationship between these elements in order to better understand the social, ideological, and political context of the novel. The analysis shows that there are relationships between two worlds: death and life, human and ghost, physical and metaphysical, natural and supernatural.

  6. New and newer[The New Physics for the Twenty-First Century

    Clark, C. [Electron and Optical Physics Division, National Institute of Standards and Technology, MD (United States)]. E-mail:


    Stephen Hawking's inaugural lecture as Lucasian Professor of Mathematics at Cambridge University in 1980 caused quite a stir. Its title - 'Is the end in sight for theoretical physics?' - raised the prospect of a unified 'theory of everything'. Hawking suggested that there was a good chance of resolving the remaining inconsistencies between the two big 'theories of something' - quantum mechanics and general relativity - before the turn of the century. My first impression on reading The New Physics for the Twenty-First Century, a collection of essays edited by science journalist Gordon Fraser, is that a theory of everything may still be attainable by the turn of the century. However, there is now 20 times more of everything in the universe than there was in the past century, 95% of which no-one has ever actually seen, or had even heard of until a few years ago - as summarized in articles by Wendy Freedman, Edward Kolb and Ronald Adler. Despite this, Michael Green describes amazing developments in string theory that could tie everything together, if one could just figure out which, if any, of the apparently infinite varieties of string theory applies to our world, and why.

  7. Finding shelter in writing: a way of configuring the Cuban exile

    María Virginia González


    Full Text Available Para pensar el campo cultural cubano resulta sugerente la imagen de un archipiélago de exilios interiores y exteriores debido a las tensiones propias de un “campo diseminado” en términos espaciales y simbólicos en el que, como ha advertido Celina Manzoni, la itinerancia ha generado “nuevas modalidades de escritura: una renovada articulación de los modos de la memoria” (Manzoni, 2012, 3. A partir de estas consideraciones, se analiza Todos se van [2006] de Wendy Guerra quien, aunque vive en Cuba, se posiciona como exiliada dentro de la isla. En la novela esta posición adquiere espesor literario a partir de un proyecto narrativo que se configura en dos movimientos: desestabilizar los géneros literarios puestos en funcionamiento para contar la historia y erigir al silencio como estrategia medular de la construcción narrativa y, al mismo tiempo, de la construcción identitaria del personaje femenino que narra la historia.

  8. Ocean Health X-Prize testing of a Simplified Spectrophotometric pH Sensor

    Darlington, R. C.; DeGrandpre, M. D.; Spaulding, R. S.; Beck, J. C.


    Since the Industrial Revolution, the world's oceans have absorbed increasing amounts of CO2, resulting in a >0.1 reduction in the pH of surface waters. This acidification of the oceans has many far reaching impacts on marine life. There is, therefore, great need of quality instrumentation to assess and follow the changing carbonate system. To address this need, we have developed a simplified spectrophotometric pH sensor with accuracy and precision suitable for sea surface measurements with special emphasis on reduced size and cost. The reduced size will allow deployment of sensors on a much wider variety of platforms than are currently possible, and the reduced cost will make the instruments available to a broader research community. This prototype pH instrument was entered into the Wendy Schmidt Ocean Health X-Prize, an incentivized global competition to spur innovation in sensors to monitor ocean acidification's impact on marine ecosystems. Results from the three phases of competition which explored accuracy, precision, and stability culminating in a one month field trial are detailed. The prototype proved to be highly accurate (+/-0.009), with good precision (+/-0.004) and stability showing drift indistinguishable from that of the validation measurements. The innovations that enabled this sensor to succeed in the competition could allow for deployment of spectrophotometric sensors on new platforms such as NOAAs Global Drifter Program, a network of non-recovered surface drifting buoys, which would greatly extend the spatial and temporal resolution of ocean acidification measurements.

  9. Portion sizes and obesity: responses of fast-food companies.

    Young, Lisa R; Nestle, Marion


    Because the sizes of food portions, especially of fast food, have increased in parallel with rising rates of overweight, health authorities have called on fast-food chains to decrease the sizes of menu items. From 2002 to 2006, we examined responses of fast-food chains to such calls by determining the current sizes of sodas, French fries, and hamburgers at three leading chains and comparing them to sizes observed in 1998 and 2002. Although McDonald's recently phased out its largest offerings, current items are similar to 1998 sizes and greatly exceed those offered when the company opened in 1955. Burger King and Wendy's have increased portion sizes, even while health authorities are calling for portion size reductions. Fast-food portions in the United States are larger than in Europe. These observations suggest that voluntary efforts by fast-food companies to reduce portion sizes are unlikely to be effective, and that policy approaches are needed to reduce energy intake from fast food.

  13. Carbon and Nitrogen Stable Isotopes in Fastfood: Signatures of Corn and Confinement

    Jahren, H.; Kraft, R.


    Americans spend more than one hundred billion dollars on restaurant fastfood each year; fastfood meals comprise a disproportionate amount of both meat and calories within the U.S. diet. Frustrated by futile attempts to gain information about the origin and production of fastfood from the companies themselves, we used carbon and nitrogen stable isotopes to infer the source of feed to meat animals, the source of fat within fries, and the extent of fertilization and confinement inherent to production. We sampled food from McDonald's, Burger King and Wendy's chains, purchasing more than 480 servings of hamburgers, chicken sandwiches and fries within geographically-distributed U.S. cities: Los Angeles, San Francisco, Denver, Detroit, Boston and Baltimore. From the entire sample set of beef and chicken, only 12 servings of beef had δ13C McDonald's and Burger King favored other vegetable oils; this differed from ingredient reports. Our results highlighted the overwhelming importance of corn agriculture within virtually every aspect of fastfood manufacture.

    Schiffries, Craig; Hazen, Robert; Hemley, Russell; Mangum, Andrea


    Advances in scientific instrumentation are important drivers of scientific discovery. The Deep Carbon Observatory (DCO) supports a diverse portfolio of scientific instrumentation initiatives worldwide as part of its ten-year quest to achieve a transformational understanding of the quantities, movements, origins, and forms of Earth's deep carbon. Substantial progress has been made in the development of a wide range of instruments, including: • Quantum cascade laser-infrared absorption spectrometer for clumped methane isotope thermometry (Shuhei Ono) • Large-radius high-mass-resolution multiple-collector isotope ratio mass spectrometer for analysis of rare isotopologues of methane and other gases (Edward Young, Douglas Rumble) • Volcanic field deployment of the laser isotope ratio-meter (Damien Weidmann) • Novel large-volume diamond anvil cell for neutron scattering (Malcolm Guthrie, Reinhard Boehler) • Novel synchrotron x-ray probes for deep carbon (Wendy Mao) • Ultrafast laser instrument for in situ measurements of elastic, electronic, and transport properties of carbon-bearing fluids and crystalline materials (Alexander Goncharov) • Combined instrument for molecular imaging in geochemistry (Andrew Steele) • Pressurized Underwater Sample Handler (Isabelle Daniel, Karyn Rogers) These and other DCO instrumentation projects are highly leveraged investments involving a large number of sponsors, partners, and collaborators.

  15. Early interventions to prevent retinal vasculopathy in diabetes: a review

    Harrison WW


    Full Text Available Wendy W Harrison, Vladimir YevseyenkovArizona College of Optometry, Midwestern University, Glendale, AZ, USAAbstract: Diabetic eye disease is a public health concern in all areas of the world as a leading cause of blindness in the working aged to elderly populations. Diabetes damages the lining of the microvasculature throughout the body through prolonged exposure to hyperglycemic conditions. The ocular changes are progressive with very little recourse for improvement once damage begins. Current treatments for the eye focus mainly on the late stages of the disease when neovascularization or edema threatens sight. Early interventions for diabetic vasculopathy involve metabolic therapy to improve blood glucose and blood pressure control. Technology improvements have a large part to play in advancing diagnosis of diabetic eye disease. These new technologies offer both structural and functional means for assessment of retinal health. This review focuses on current treatments for diabetic eye disease at all stages with an emphasis on new and early interventions. It also details established and emerging technologies used for earlier detection of diabetic eye disease, which is vital to the development and approval of much needed treatments targeted at earlier stages of diabetic retinopathy. Possible future treatments should be aimed to prevent retinal vasculopathy from progressing. This review will explore current research on this topic and what is needed moving forward.Keywords: diabetes, diabetic retinopathy, vascular disease

  16. Critical role for BIM in T cell receptor restimulation-induced death

    Fleisher Thomas A


    Full Text Available Abstract Background Upon repeated or chronic antigen stimulation, activated T cells undergo a T cell receptor (TCR-triggered propriocidal cell death important for governing the intensity of immune responses. This is thought to be chiefly mediated by an extrinsic signal through the Fas-FasL pathway. However, we observed that TCR restimulation still potently induced apoptosis when this interaction was blocked, or genetically impaired in T cells derived from autoimmune lymphoproliferative syndrome (ALPS patients, prompting us to examine Fas-independent, intrinsic signals. Results Upon TCR restimulation, we specifically noted a marked increase in the expression of BIM, a pro-apoptotic Bcl-2 family protein known to mediate lymphocyte apoptosis induced by cytokine withdrawal. In fact, T cells from an ALPS type IV patient in which BIM expression is suppressed were more resistant to restimulation-induced death. Strikingly, knockdown of BIM expression rescued normal T cells from TCR-induced death to as great an extent as Fas disruption. Conclusion Our data implicates BIM as a critical mediator of apoptosis induced by restimulation as well as growth cytokine withdrawal. These findings suggest an important role for BIM in eliminating activated T cells even when IL-2 is abundant, working in conjunction with Fas to eliminate chronically stimulated T cells and maintain immune homeostasis.

  17. Corn content of French fry oil from national chain vs. small business restaurants.

    Jahren, A Hope; Schubert, Brian A


    Several issues, ranging from sustainability to health, may interest the consumers in the corn content of their food. However, because restaurants are excluded from the Nutrition Labeling and Education Act of 1990, national chain restaurants provide nonspecific ingredient information and small businesses supply none. We measured the carbon isotope composition of fry oil in French fries purchased from 68 (67%) of the 101 national chain fast food restaurants on Oahu (i.e., McDonald's, Burger King, Wendy's, Arby's, and Jack in the Box), and paired this with a similar number of small businesses (n = 66) to calculate minimum percent contribution of corn to total fry oil. We found that the majority (69%) of the national chain restaurants served fries containing corn oil, whereas this was true for only a minority (20%) of the small businesses. Corn oil is more expensive than soybean oil (for example) when purchased from a small business supplier, suggesting that large-scale corporate agreements are necessary to make corn oil frying cost-effective. When considering French fry oil along with corn-fed beef and chicken, as well as high-fructose corn syrup-sweetened soda, we see the pervasive influence of corn as an ingredient in national chain fast food.

  18. Bicycles, Airplanes and Peter Pans: Flying Scenes in Steven Spielberg's Films

    Emilio Audissino


    Full Text Available In Steven Spielberg's cinema the flight is a recurring theme. Flying scenes can be sorted into two classes: those involving a realistic flight – by aircraft – and those involving a magical flight – by supernatural powers. The realistic flight is influenced by the war stories of Spielberg's father – a radio man in U.S. Air-force during WWII – and it is featured in such films as Empire of the Sun (1987, Always (1989, and 1941 (1979. The magical flight is influenced by James M. Barries' character Peter Pan (Peter and Wendy, 1911, which is quoted directly in E.T. the Extraterrestrial (1982 and, above all, in Hook (1991, which is a sequel to Barrie's story. These two types of flying scenes are analysed as to their meanings, compared to the models that influenced them, and surveyed as to their evolution across Spielberg's films. A central case study is the episode The Mission from Amazing Stories (1985, in which the realistic and the magical flights overlap.

  20. Authoritarian populism contra "Bildung": anti-intellectualism and the neoliberal assault on the Liberal Arts

    Jeremiah Morelock


    Full Text Available A synergistic movement is taking place in American society combining authoritarian populism, the neoliberal transformation of the university, and anti-intellectualism. In the first part of this paper, I pin my notion of intellectualism (and hence anti-intellectualism to a specific frame of reference, namely the German notion of "Bildung" as it is discussed in writings of Nietzsche and Adorno, which I associate loosely with the traditional American liberal arts model of higher education. In the second part of the paper, I outline the neoliberal assault on the liberal arts, rooting my analysis in Wendy Brown’s work, which is influenced by Foucault. In the third part of the paper, I describe the relationship of this anti-intellectualism to the rise of populism and the threat of authoritarianism in the United States. In the final section I tie the discussion into the general analysis of Horkheimer and Adorno’s analysis of fascist tendencies in liberal-democracies, emphasizing the continued relevance of their ideas to contemporary developments in education and beyond. Keywords: Liberal arts; Neoliberalism; Intellectuals; Populism; Authoritarianism.

    Full Text Available Margot E Shields, Wendy E Hovdestad, Charles P Gilbert, Lil E Tonmyr Public Health Agency of Canada, Ottawa, ON, Canada Objective: The aim of this study was to examine the associations between childhood maltreatment (CM and COPD in adulthood.Methods: Data were from 15,902 respondents to the 2012 Canadian Community Health Survey – Mental Health. Multiple logistic regression models were used to examine associations between CM and COPD and the role of smoking and mental and substance use variables as mediators in associations.Results: COPD in adulthood was related to CM, with associations differing by sex. Among females, COPD was related to childhood physical abuse (CPA, childhood sexual abuse, and childhood exposure to intimate partner violence, but in the fully adjusted models, the association with CPA did not persist. Among males, COPD was related to childhood exposure to intimate partner violence and severe and frequent CPA, but these associations did not persist in the fully adjusted models.Conclusion: Results from this study establish CM as a risk factor for COPD in adulthood. A large part of the association is attributable to cigarette smoking, particularly for males. These findings underscore the importance of interventions to prevent CM as well as programs to assist victims of CM in dealing with tobacco addiction.

    Olumi, Aria F


    Prostate cancer is the most frequently diagnosed cancer in males in developed countries. To identify common prostate cancer susceptibility alleles, we genotyped 211,155 SNPs on a custom Illumina array (iCOGS) in blood DNA from 25,074 prostate cancer cases and 24,272 controls from the international PRACTICAL Consortium. Twenty-three new prostate cancer susceptibility loci were identified at genome-wide significance (P<5×10(-8)). More than 70 prostate cancer susceptibility loci, explaining ~30% of the familial risk for this disease, have now been identified. On the basis of combined risks conferred by the new and previously known risk loci, the top 1% of the risk distribution has a 4.7-fold higher risk than the average of the population being profiled. These results will facilitate population risk stratification for clinical studies. Copyright © 2014 Elsevier Inc. All rights reserved.

  10. Slowly Shifting a Culture of Teaching in Higher Education: A Case Study of Biology Instructors' Micro-Processes of Collaborative Inquiry into Teaching and Learning

    Neuwald, Anuschka

    The Vision and Change reports (American Association for the Advancement of Science, 2011, 2013) have identified a need for change in undergraduate biology education, emphasizing student learning of content knowledge and competencies. Missing from this report and larger efforts to improve undergraduate education (Brainard, 2007; Henderson et al., 2011; Sunal et al., 2001) are guidelines for how to support instructors' professional learning to change teaching practices. I am exploring one possible support structure by studying a group of seven biology instructors that are engaged in a collaborative process over two semesters. This process is modeled after Lesson Study (Lewis et al., 2006), a form of cyclical inquiry-based professional learning activities. The purpose of this qualitative case study is to examine the micro-processes of this collaboration and how these micro-processes afford and limit the ability to change one's teaching practices. Wenger's (1998) concept of "community of practice" provides a theoretical framework for data analysis. I view an instructor's professional learning as social and situated, involving negotiation of new meanings, boundaries, and participation as part of an on-going collaboration. Data analysis shows that negotiation of meaning, characterized by friction and dissonance, is a normal part of the micro-processes of collaborative group work. There are three friction points that are intertwined and influence each other: 1) rhythmic ebb and flow of negotiation about a common professional goal for the instructors and a common learning goal for undergraduates in biology, 2) pressure of time to produce an outcome, and 3) grappling with collective agency, authority and capacity. I argue that these friction points are necessary and important for understanding the micro-processes of negotiation in a collaborative process. Furthermore, this study contributes to literature examining how the use of collaborative processes that are often

  12. Special issue on electron cyclotron wave physics, technology, and applications - Part 2

    Uckan, Nermin A.


    This issue of Fusion Science and Technology (FS and T) contains a compendium of full-length, peer-reviewed papers on electron cyclotron (EC) wave physics, technology, and applications on magnetically confined plasmas. The interest in this special issue started with a simple question from a single individual who asked if he could submit for publication in FS and T his paper ''ITER ECH Front Steering Upper Launcher,'' parts of which he was planning to present at the 14th Joint Workshop on Electron Cyclotron Emission and Electron Cyclotron Resonance Heating, Santorini Island, Greece, May 2006. Such interest quickly grew, and the decision was made to offer the same opportunity to other workshop participants as well as to other interested researchers from around the world to contribute to a special FS and T issue on EC wave physics, technology, and applications. The person who started this ''wave'' of interest is no other than Dr. Mark Henderson, who was later drafted and kindly agreed to serve as the guest editor for this issue. The worldwide research program on EC wave physics, technology, and applications has shown impressive progress over the past couple of years, and much of this progress is reflected in the fifty or so papers that are included in this two-part special issue - part 1 in August 2007 and part 2 in January 2008. To complement the contributed papers, several informative reviews, which will be valuable for years to come, were also invited and are included. These review papers provide an objective summary of the current state of the art in EC emission research, theory of EC waves, EC heating and current drive experiments, gyrotron development, launcher development, and transmission systems. In preparation for ITER, this special issue is timely and should be of interest to those already working in the field and to the new generation of scientists and engineers who will be the ones to design, build, and carry out experiments on ITER.

    Shiqi Zhou


    Full Text Available Thermodynamic and structural properties of liquids are of fundamental interest in physics, chemistry, and biology, and perturbation approach has been fundamental to liquid theoretical approaches since the dawn of modern statistical mechanics and remains so to this day. Although thermodynamic perturbation theory (TPT is widely used in the chemical physics community, one of the most popular versions of the TPT, i.e. Zwanzig (Zwanzig, R. W. J. Chem. Phys. 1954, 22, 1420-1426 1st-order high temperature series expansion (HTSE TPT and its 2nd-order counterpart under a macroscopic compressibility approximation of Barker-Henderson (Barker, J. A.; Henderson, D. J. Chem. Phys. 1967, 47, 2856-2861, have some serious shortcomings: (i the nth-order term of the HTSE is involved with reference fluid distribution functions of order up to 2n, and the higher-order terms hence progressively become more complicated and numerically inaccessible; (ii the performance of the HTSE rapidly deteriorates and the calculated results become even qualitatively incorrect as the temperature of interest decreases. This account deals with the developments that we have made over the last five years or so to advance a coupling parameter series expansion (CPSE and a non hard sphere (HS perturbation strategy that has scored some of its greatest successes in overcoming the above-mentioned difficulties. In this account (i we expatiate on implementation details of our schemes: how input information indispensable to high-order truncation of the CPSE in both the HS and non HS perturbation schemes is calculated by an Ornstein-Zernike integral equation theory; how high-order thermodynamic quantities, such as critical parameters and excess constant volume heat capacity, are extracted from the resulting excess Helmholtz free energy with irregular and inevitable numerical errors; how to select reference potential in the non HS perturbation scheme. (ii We give a quantitative analysis on why

  14. A Stable U Isotopic Perspective on the U Budget and Global Extent of Modern Anoxia in the Ocean.

    Tissot, F.; Dauphas, N.


    Isotopic fractionation between U4+ and U6+makes U stable isotopes potential tracers of global paleoredox conditions. In this work [1], we put the U-proxy up to a test against a highly constrained system: the modern ocean. We measured a large number of seawater samples from geographically diverse locations and found that the open ocean has a homogenous isotopic composition at δ238USW= -0.392 ± 0.005 ‰ (rel. to CRM-112a). From our measurement of rock samples (n=64) and compilations of literature data (n=380), we then estimated the U isotopic compositions of the various reservoirs involved in the modern oceanic U budget, as well as the fractionation factors associated with U incorporation into those reservoirs. Using a steady-state model, we compared the isotopic composition of the seawater predicted by the four most recent U oceanic budgets [2-5] to the modern seawater value we measured. Three of these budgets [2-4] predict a seawater isotopic composition in very good agreement with the observed δ238USW, which strengthens our confidence in the isotopic fractionation factors associated with each deposition environment and the fact that U is at steady-state in the modern ocean. The U oceanic budget of Henderson and Anderson (2003) does not reproduce the observed seawater composition because the U flux to anoxic/euxinic sediments relative to the total U flux out of the ocean is high in their model, which our analysis shows cannot be correct. The U isotopic composition of seawater is used to constrain the extent of anoxia in the modern ocean (% of seafloor covered by anoxic/euxinic sediments), which is 0.21 ± 0.09 %. This work demonstrates that stable isotopes of U can indeed trace the extent of anoxia in the modern global ocean, thereby validating the application of U isotope measurements to paleoredox reconstructions. Based on the above work, we will present the best estimate of the modern oceanic U budget. [1] Tissot F.L.H., Dauphas N. (2015) Geochim Cosmochim

    Remmes, N; Mundy, D; Classic, K; Beltran, C; Kruse, J; Herman, M; Stoker, J; Nelson, K; Bues, M


    Purpose: To verify acceptably low dose levels around two newly constructed identical pencil beam scanning proton therapy facilities and to evaluate accuracy of pre-construction shielding calculations. Methods: Dose measurements were taken at select points of interest using a WENDI-2 style wide-energy neutron detector. Measurements were compared to pre-construction shielding calculations. Radiation badges with neutron dose measurement capabilities were worn by personnel and also placed at points throughout the facilities. Seven neutron and gamma detectors were permanently installed throughout the facility, continuously logging data. Potential activation hazards have also been investigated. Dose rates near water tanks immediately after prolonged irradiation have been measured. Equipment inside the treatment room and accelerator vault has been surveyed and/or wipe tested. Air filters from air handling units, sticky mats placed outside of the accelerator vault, and water samples from the magnet cooling water loops have also been tested. Results: All radiation badges have been returned with readings below the reporting minimum. Measurements of mats, air filters, cooling water, wipe tests and surveys of equipment that has not been placed in the beam have all come back at background levels. All survey measurements show the analytical shielding calculations to be conservative by at least a factor of 2. No anomalous events have been identified by the building radiation monitoring system. Measurements of dose rates close to scanning water tanks have shown dose rates of approximately 10 mrem/hr with a half-life less than 5 minutes. Measurements around the accelerator show some areas with dose rates slightly higher than 10 mrem/hr. Conclusion: The shielding design is shown to be adequate. Measured dose rates are below those predicted by shielding calculations. Activation hazards are minimal except in certain very well defined areas within the accelerator vault and for objects

  20. Child and adolescent fast-food choice and the influence of calorie labeling: a natural experiment.

    Elbel, B; Gyamfi, J; Kersh, R


    Obesity is an enormous public health problem and children have been particularly highlighted for intervention. Of notable concern is the fast-food consumption of children . However, we know very little about how children or their parents make fast-food choices, including how they respond to mandatory calorie labeling. We examined children's and adolescents' fast-food choice and the influence of calorie labels in low-income communities in New York City (NYC) and in a comparison city (Newark, NJ). Natural experiment: Survey and receipt data were collected from low-income areas in NYC, and Newark, NJ (as a comparison city), before and after mandatory labeling began in NYC. Study restaurants included four of the largest chains located in NYC and Newark: McDonald's, Burger King, Wendy's and Kentucky Fried Chicken. A total of 349 children and adolescents aged 1-17 years, who visited the restaurants with their parents (69%) or alone (31%) before or after labeling was introduced. In total, 90% were from racial or ethnic minority groups. We found no statistically significant differences in calories purchased before and after labeling; many adolescents reported noticing calorie labels after their introduction (57% in NYC) and a few considered the information when ordering (9%). Approximately 35% of adolescents ate fast food six or more times per week and 72% of adolescents reported that taste was the most important factor in their meal selection. Adolescents in our sample reported that parents have some influence on their meal selection. Adolescents in low-income communities notice calorie information at similar rates as adults, although they report being slightly less responsive to it than adults. We did not find evidence that labeling influenced adolescent food choice or parental food choices for children in this population.

  1. Energy contribution of sugar-sweetened beverage refills at fast-food restaurants.

    Breck, Andrew; Cantor, Jonathan H; Elbel, Brian


    To identify demographic and consumer characteristics associated with refilling a soft drink at fast-food restaurants and the estimated energy content and volume of those refills. Logistic and linear regression with cross-sectional survey data. Data include fast-food restaurant receipts and consumer surveys collected from restaurants in New York City (all boroughs except Staten Island), and Newark and Jersey City, New Jersey, during 2013 and 2014. Fast-food restaurant customers (n 11795) from ninety-eight restaurants. Thirty per cent of fast-food customers ordered a refillable soft drink. Nine per cent of fast-food customers with a refillable soft drink reported refilling their beverage (3 % of entire sample). Odds of having a beverage refill were higher among respondents with a refillable soft drink at restaurants with a self-serve refill kiosk (adjusted OR (aOR)=7·37, Prestaurant (aOR=4·45, P<0·001). KFC (aOR=2·18, P<0·001) and Wendy's (aOR=0·41, P<0·001) customers had higher and lower odds, respectively, of obtaining a refill, compared with Burger King customers. Respondents from New Jersey (aOR=1·47, P<0·001) also had higher odds of refilling their beverage than New York City customers. Customers who got a refill obtained on average 29 more 'beverage ounces' (858 ml) and 250 more 'beverage calories' (1046 kJ) than customers who did not get a refill. Refilling a beverage was associated with having obtained more beverage calories and beverage ounces. Environmental cues, such as the placement and availability of self-serve beverage refills, may influence consumer beverage choice.

  2. A toy story: Association between young children's knowledge of fast food toy premiums and their fast food consumption.

    Longacre, Meghan R; Drake, Keith M; Titus, Linda J; Cleveland, Lauren P; Langeloh, Gail; Hendricks, Kristy; Dalton, Madeline A


    Fast food restaurants spend millions of dollars annually on child-targeted marketing, a substantial portion of which is allocated to toy premiums for kids' meals. The objectives of this study were to describe fast food toy premiums, and examine whether young children's knowledge of fast food toy premiums was associated with their fast food consumption. Parents of 3- to 5-year old children were recruited from pediatric and WIC clinics in Southern New Hampshire, and completed a cross-sectional survey between April 2013-March 2014. Parents reported whether their children usually knew what toys were being offered at fast food restaurants, and whether children had eaten at any of four restaurants that offer toy premiums with kids' meals (McDonald's, Burger King, Subway, Wendy's) during the 7 days preceding the survey. Seventy-one percent of eligible parents participated (N = 583); 48.4% did not receive any education beyond high school, and 27.1% of children were non-white. Half (49.7%) the children had eaten at one or more of the four fast food restaurants in the past week; one-third (33.9%) had eaten at McDonald's. The four restaurants released 49 unique toy premiums during the survey period; McDonald's released half of these. Even after controlling for parent fast food consumption and sociodemographics, children were 1.38 (95% CI = 1.04, 1.82) times more likely to have consumed McDonald's if they usually knew what toys were offered by fast food restaurants. We did not detect a relationship between children's toy knowledge and their intake of fast food from the other restaurants. In this community-based sample, young children's knowledge of fast food toys was associated with a greater frequency of eating at McDonald's, providing evidence in support of regulating child-directed marketing of unhealthy foods using toys.

  3. Child-targeted fast-food television advertising exposure is linked with fast-food intake among pre-school children.

    Dalton, Madeline A; Longacre, Meghan R; Drake, Keith M; Cleveland, Lauren P; Harris, Jennifer L; Hendricks, Kristy; Titus, Linda J


    To determine whether exposure to child-targeted fast-food (FF) television (TV) advertising is associated with children's FF intake in a non-experimental setting. Cross-sectional survey conducted April-December 2013. Parents reported their pre-school child's TV viewing time, channels watched and past-week FF consumption. Responses were combined with a list of FF commercials (ads) aired on children's TV channels during the same period to calculate children's exposure to child-targeted TV ads for the following chain FF restaurants: McDonald's, Subway and Wendy's (MSW). Paediatric and Women, Infants, and Children (WIC) clinics in New Hampshire, USA. Parents (n 548) with a child of pre-school age. Children's mean age was 4·4 years; 43·2 % ate MSW in the past week. Among the 40·8 % exposed to MSW ads, 23·3 % had low, 34·2 % moderate and 42·5 % high exposure. McDonald's accounted for over 70 % of children's MSW ad exposure and consumption. Children's MSW consumption was significantly associated with their ad exposure, but not overall TV viewing time. After adjusting for demographics, socio-economic status and other screen time, moderate MSW ad exposure was associated with a 31 % (95 % CI 1·12, 1·53) increase and high MSW ad exposure with a 26 % (95 % CI 1·13, 1·41) increase in the likelihood of consuming MSW in the past week. Further adjustment for parent FF consumption did not change the findings substantially. Exposure to child-targeted FF TV advertising is positively associated with FF consumption among children of pre-school age, highlighting the vulnerability of young children to persuasive advertising and supporting recommendations to limit child-directed FF marketing.

  4. The impact of Border policy effect on cross-border ethnic areas

    Bie, Q. L.; Zhou, S. Y.; Li, C. S.


    Boundary effect analysis is related to border policy making in the cross-border ethnic area. The border effect literatures show that geographic boundaries have obvious impacts on economic, social and cultural relations in both sides of a nation border. Particularly in cross-border ethnic areas, each ethnic group has strong internal spatial structure relevance, and the boundary effect is more obvious. However, most of China's border areas are cross-border ethnic areas, each of border issues is unique. Under this perspective, we analyze the border effects of various boundaries can provide basis for formulating border management policies. For small scale of cross-border ethnic minority areas, how to formulate the boundary management policy is a good question to explore. This paper is demonstrated by a study of the impact of border management policies in Dehong Dai and Jingpo Autonomous Prefecture in Yunnan Province at the border area to Burma. The comparative method is used to analysis the border management policies in past 50 decades for the border area of Yunnan Province .This research aims to define trends within border policy and its influences to national security. This paper also examines Wendy Brown's liberal theory of border management policy. We found that it is not suitable for Sino-Burma border area. The conclusion is that the changes or instability of international economic and political situation has more influence to this cross-border ethnic area, and only innovative policy will be effective in cross-border ethnic area. So the border management policies should reflect the change of international context.

The goal of this study was to perform a more detailed analysis to validate both of these findings for current smokers versus nonsmokers within the benefit-covered population of a large US employer. Patients and methods: This study involved the analysis of incurred medical and pharmacy claims for employee and spouse health plan enrollees of a single US-based employer during 2010. Multivariate regression models were used to compare data by active or never-smoker status for preventive care services and medication adherence for chronic conditions. Analysis controlled for demographic variables, chronic condition prevalence, and depression. Results: Controlling for demographic variables and comorbid conditions, smokers had significantly lower cancer screening rates, with absolute reductions of 6%–13%. Adherence to chronic medication use for hypertension was also significantly lower among smokers, with nearly 7% fewer smokers having a medication possession ratio of ≥80%. Smokers were less adherent to depression medications (relative risk =0.79 than nonsmokers (P=0.10. While not statistically significant, smokers were consistently less adherent to all other medications than nonsmokers. Conclusion: Current smokers are less compliant with recommended preventive care and medication use than nonsmokers, likely contributing to smoking-related employer costs. Awareness of these care gaps among smokers and

    Warnick, W. K.; Warburton, J.; Breen, K.; Wiggins, H. V.; Larson, A.; Behr, S.


    PolarTREC-Teachers and Researchers Exploring and Collaborating is a three-year (2007-2009) teacher professional development program celebrating the International Polar Year (IPY) that will advance polar science education by bringing K-12 educators and polar researchers together in hands-on field experiences in the Arctic and Antarctic. PolarTREC builds on the strengths of the existing TREC program in the Arctic, an NSF supported program managed by the Arctic Research Consortium of the US (ARCUS), to embrace a wide range of activities occurring at both poles during and after IPY. PolarTREC will foster the integration of research and education to produce a legacy of long-term teacher-researcher collaborations, improved teacher content knowledge through experiences in scientific inquiry, and broad public interest and engagement in polar science and IPY. PolarTREC will enable thirty-six teachers to spend two to six weeks in the Arctic or Antarctic, working closely with researchers investigating a wide range of IPY science themed topics such as sea-ice dynamics, terrestrial ecology, marine biology, atmospheric chemistry, and long-term climate change. While in the field, teachers and researchers will communicate extensively with their colleagues, communities, and hundreds of students of all ages across the globe, using a variety of tools including satellite phones, online journals, podcasts and interactive "Live from IPY" calls and web-based seminars. The online outreach elements of the project convey these experiences to a broad audience far beyond the classrooms of the PolarTREC teachers. In addition to field research experiences, PolarTREC will support teacher professional development and a sustained community of teachers, scientists, and the public through workshops, Internet seminars, an e-mail listserve, and teacher peer groups.

There is also limited evidence linking clinical audit with improvements in care delivery. Pregnancy care was chosen because there are well defined and agreed clinical standards against which to measure the delivery of pregnancy care. A clinical audit using these standards addresses both gaps in the literature.Methods: Standard methodological processes were used to develop the audit tool. Literature informed the processes. Data were collected in 2009–2010 using the tool described in the paper. Reliability testing was completed in September 2011.Results: An audit tool to measure pregnancy care was developed and applied to 354 health records to enable analysis of adherence to organizational expectations of care. Reliability testing of the tool achieved an overall kappa of 0.896.Conclusion: Developing an audit tool based on processes described in the literature is labor intensive and resource dependent, however it results in a robust, reliable, valid tool that can be used in diverse maternity services. Stakeholder participation from the outset ensures ongoing engagement for the duration of a clinically based project spanning several years

Dyschromia and fine lines/wrinkles are common clinical manifestations of photodamaged skin. Purpose: This single-center clinical trial was conducted to assess the efficacy and tolerability of a new multifunctional facial primer (camouflage, broad-spectrum SPF 50, and a treatment for hyperpigmentation when used by females with mild-to-moderate facial hyperpigmentation and fine lines due to photoaging over a course of 12 weeks. Patients and methods: Subjects were provided test material (Even Up-Clinical Pigment Perfector and supporting products to use on their face and neck. Products were used according to specific application instructions. Clinical grading for efficacy and tolerability assessments were performed by an expert grader at baseline, baseline (post-application primer, week 4, week 8, week 12, and week 12 (post-application primer. Standardized digital photographs were taken, and self-assessment questionnaires were conducted. Results: Twenty-eight female subjects completed the 12-week trial. The facial primer improved scores for the appearance of hyperpigmentation and other photoaging parameters immediately after the first application. The treatment also showed a progressive improvement in the clinical assessment of hyperpigmentation and other photoaging parameters over the 12-week trial. These long-term benefits can be attributed to an improvement in the underlying skin condition. The facial primer was well tolerated. Subject questionnaires showed that the product was highly rated at all visits. Conclusion: The facial primer was shown to be effective and well tolerated for immediate and long-term improvement in the appearance

  12. Benchmarking shielding simulations for an accelerator-driven spallation neutron source

    Nataliia Cherkashyna


    Full Text Available The shielding at an accelerator-driven spallation neutron facility plays a critical role in the performance of the neutron scattering instruments, the overall safety, and the total cost of the facility. Accurate simulation of shielding components is thus key for the design of upcoming facilities, such as the European Spallation Source (ESS, currently in construction in Lund, Sweden. In this paper, we present a comparative study between the measured and the simulated neutron background at the Swiss Spallation Neutron Source (SINQ, at the Paul Scherrer Institute (PSI, Villigen, Switzerland. The measurements were carried out at several positions along the SINQ monolith wall with the neutron dosimeter WENDI-2, which has a well-characterized response up to 5 GeV. The simulations were performed using the Monte-Carlo radiation transport code geant4, and include a complete transport from the proton beam to the measurement locations in a single calculation. An agreement between measurements and simulations is about a factor of 2 for the points where the measured radiation dose is above the background level, which is a satisfactory result for such simulations spanning many energy regimes, different physics processes and transport through several meters of shielding materials. The neutrons contributing to the radiation field emanating from the monolith were confirmed to originate from neutrons with energies above 1 MeV in the target region. The current work validates geant4 as being well suited for deep-shielding calculations at accelerator-based spallation sources. We also extrapolate what the simulated flux levels might imply for short (several tens of meters instruments at ESS.

    Social media is increasingly being used as a means of recruiting participants, particularly for investigators whose areas of interest involve rare conditions or hard-to-reach populations. However, much of the literature to date has focused on paid advertisement recruitment. We used Lynch syndrome (LS), a rare hereditary cancer syndrome, as a model to demonstrate the successful partnership between researchers and a Web-based patient education and advocacy organization to facilitate participant recruitment. Recruitment was undertaken in partnership with Lynch Syndrome International (LSI), an advocacy organization with a strong social media presence. After LSI published our study information, participants followed up via email or phone call. Following prescreening and consent, interested and eligible participants were then sent a secure survey link. Within 36 hours of a single Facebook post by the site administrators for LSI, over 150 individuals responded via phone or email. Sixty-five individuals were sent the survey link and 57 individuals completed the survey (88% response rate). Of note, these 57 individuals were geographically diverse within the Unites States, representing LS patients from 26 different states. This approach has several advantages, including recruitment through a trusted source outside of a clinical setting, higher response rates, and cost-effectiveness with a small research team in a relatively short amount of time. Overall, social media recruitment with a trusted online partner can be highly effective in hard-to-reach clinical populations, such as patients with LS. However, this approach requires additional effort for eligibility screening. ©Allison M Burton-Chase, Wendy M Parker, Kelsey Hennig, Faith Sisson, Linda L Bruzzone.

  14. On the inclusion of the interfacial area between phases in the physical and mathematical description of subsurface multiphase flow. 1997 annual progress report

    Gray, W.G.


    'This research is part of a joint project with Dr. Andrew F. B. Tompson of Lawrence Livermore National Lab. and Dr. Wendy E. Soll of Los Alamos National Lab. The work is designed to integrate a continuum theory approach to multiphase flow modeling (Gray) with lattice Doltzmann studies (Soll) and study of the model in the context of a field simulation (Tompson). Because of some difficulties with the funding procedure, the support for Drs. Tompson and Soll was delayed such that it begins with the second year during which the author will be supported. Because of this fact, the efforts to integrate the theory with the modeling efforts has been delayed but will be able to be approached with particular vigor during this coming year. The author has met with Drs. Soll and Tompson and plan to meet with them again next month to ensure that the efforts are coordinated. During this first year, funding has been used to advance the theory and develop a basic understanding that will assist in development of the simulation models. It should be noted that in addition to this grant. The author is supported by a subcontract of part of a DOE grant to Cornell (PI Carlo Monte-magno) under this same funding program. Both grants require development of theory and are thus related. However, the interactions and ultimate goals of the two studies are different. Simplistically, one might differentiate between the two projects in that the DOE-Cornell grant is concerned with the equilibrium states of the system and the parameters needed to describe those states while the present grant is concerned with dynamic processes and the parameters needed for their description. It is not possible to definitively compartmentalize the findings made in my studies of multiphase flow as belonging exclusively to one grant or the other.'

The aims of this study were to review renal function and renal volumes in children who had a history of neonatal hypertension. Methods: Children with a history of neonatal hypertension from January 2001 to December 2008 were included in the study during 2011. Blood pressure, weight, height, and body mass index were recorded. Renal ultrasound with 3D volume, urine for electrolytes, albumin, ß2 microglobulin, and blood for electrolytes, urea, creatinine, calcium, phosphate, renin, and aldosterone were collected depending on parental consent. Results: Of the 41 neonates with neonatal hypertension, eleven (27% were included in the study (six died; 24 moved interstate or declined involvement. One child (9% was still on antihypertensive medication and one was found to be hypertensive on review. This child had small volume kidneys and albuminuria. Three out of nine renal volume measurements were low (33% and two out of eleven had renal scarring (18%. The six available renin/aldosterone results were normal. Conclusion: This study suggests there are long-term renal and blood pressure implications for neonates with hypertension and ongoing surveillance of blood pressure and renal function should be performed throughout childhood and into early adulthood. Keywords: neonate, hypertension, renal ultrasound, 3D

  16. Cohabitation and Child Wellbeing.

    Manning, Wendy D


    In recent decades, writes Wendy Manning, cohabitation has become a central part of the family landscape in the United States-so much so that by age 12, 40 percent of American children will have spent at least part of their lives in a cohabiting household. Although many children are born to cohabiting parents, and cohabiting families come in other forms as well, the most common cohabiting arrangement is a biological mother and a male partner. Cohabitation, Manning notes, is associated with several factors that have the potential to reduce children's wellbeing. Cohabiting families are more likely than married families to be poor, and poverty harms children in many ways. Cohabiting parents also tend to have less formal education-a key indicator of both economic and social resources-than married parents do. And cohabiting parent families don't have the same legal protections that married parent families have. Most importantly, cohabitation is often a marker of family instability, and family instability is strongly associated with poorer outcomes for children. Children born to cohabiting parents see their parents break up more often than do children born to married parents. In this way, being born into a cohabiting family sets the stage for later instability, and children who are born to cohabiting parents appear to experience enduring deficits of psychosocial wellbeing. On the other hand, stable cohabiting families with two biological parents seem to offer many of the same health, cognitive, and behavioral benefits that stable married biological parent families provide. Turning to stepfamilies, cohabitation's effects are tied to a child's age. Among young children, living in a cohabiting stepfamily rather than a married stepfamily is associated with more negative indicators of child wellbeing, but this is not so among adolescents. Thus the link between parental cohabitation and child wellbeing depends on both the type of cohabiting parent family and the age of the

  17. Salt Solubility Products of Diprenorphine Hydrochloride, Codeine and Lidocaine Hydrochlorides and Phosphates – Novel Method of Data Analysis Not Dependent on Explicit Solubility Equations

    Gergely Völgyi


    Full Text Available A novel general approach was described to address many of the challenges of salt solubility determination of drug substances, with data processing and refinement of equilibrium constants encoded in the computer program pDISOL-XTM. The new approach was illustrated by the determinations of the solubility products of diprenorphine hydrochloride, codeine hydrochloride and phosphate, lidocaine hydrochloride and phosphate at 25 oC, using a recently-optimized saturation shake-flask protocol.  The effects of different buffers (Britton-Robinson universal and Sörensen phosphate were compared. Lidocaine precipitates were characterized by X-ray powder diffraction (XRPD and polarization light microscopy. The ionic strength in the studied systems ranged from 0.25 to 4.3 M. Codeine (and possibly diprenorphine chloride were less soluble than the phosphates for pH > 2. The reverse trend was evident with lidocaine.  Diprenorphine saturated solutions showed departure from the predictions of the Henderson-Hasselbalch equation in alkaline (pH > 9 solutions, consistent with the formation of a mixed-charge anionic dimer.

  18. Motorist actions at a crosswalk with an in-pavement flashing light system.

    Karkee, Ganesh J; Nambisan, Shashi S; Pulugurtha, Srinivas S


    An in-pavement flashing light system is used at crosswalks to alert motorists and pedestrians of possible conflicts and to influence their behavior to enhance safety. The relative behaviors of the drivers and the pedestrians affect safety. An evaluation of motorist behavior at a pedestrian crosswalk with an in-pavement flashing light system is presented in this manuscript. Field observations provide the basis to evaluate motorist behavior at a crosswalk with an in-pavement flashing light system. Outcomes of pedestrian and motorists actions were observed to quantify measures of effectiveness (MOEs) such as yielding behavior of motorists, vehicle speeds, and yielding distance from the crosswalk. A before-and-after study design was used. The before condition was prior to the activation of the in-pavement flashing light system and the after condition was after the activation of the in-pavement flashing light system. The study was conducted on a relatively low-volume roadway located in the Henderson, Nevada. The significance of the differences in the MOEs between the 2 study periods was evaluated using statistical analysis tools such as a one-tailed test for proportions and the Welch-Satterthwaite t-test. The results show that the installation of the in-pavement flashing light system increased the yielding behavior of motorists significantly (P pavement flashing light system is seen to be effective to improve motorists' yielding behavior and the speeds of vehicles were also observed to decrease in the presence of pedestrians.

  19. The role of solvation in the binding selectivity of the L-type calcium channel.

    Boda, Dezső; Henderson, Douglas; Gillespie, Dirk


    We present grand canonical Monte Carlo simulation results for a reduced model of the L-type calcium channel. While charged residues of the protein amino acids in the selectivity filter are treated explicitly, most of the degrees of freedom (including the rest of the protein and the solvent) are represented by their dielectric response, i.e., dielectric continua. The new aspect of this paper is that the dielectric coefficient in the channel is different from that in the baths. The ions entering the channel, thus, cross a dielectric boundary at the entrance of the channel. Simulating this case has been made possible by our recent methodological development [D. Boda, D. Henderson, B. Eisenberg, and D. Gillespie, J. Chem. Phys. 135, 064105 (2011)]. Our main focus is on the effect of solvation energy (represented by the Born energy) on monovalent vs. divalent ion selectivity in the channel. We find no significant change in selectivity by changing the dielectric coefficient in the channel because the larger solvation penalty is counterbalanced by the enhanced Coulomb attraction inside the channel as soon as we use the Born radii (fitted to experimental hydration energies) to compute the solvation penalty from the Born equation.

  20. Thermodynamics and elastic moduli of fluids with steeply repulsive potentials

    Heyes, D. M.


    Analytic expressions for the thermodynamic properties and elastic moduli of molecular fluids interacting with steeply repulsive potentials are derived using Rowlinson's hard-sphere perturbation treatment which employs a softness parameter, λ specifying the deviation from the hard-sphere potential. Generic potentials of this form might be used to represent the interactions between near-hard-sphere stabilized colloids. Analytic expressions for the equivalent hard-sphere diameter of inverse power [ɛ(σ/r)n where ɛ sets the energy scale and σ the distance scale] exponential and logarithmic potential forms are derived using the Barker-Henderson formula. The internal energies in the hard-sphere limit are predicted essentially exactly by the perturbation approach when compared against molecular dynamics simulation data using the same potentials. The elastic moduli are similarly accurately predicted in the hard-sphere limit, as they are trivially related to the internal energy. The compressibility factors from the perturbation expansion do not compare as favorably with simulation data, and in this case the Carnahan-Starling equation of state prediction using the analytic effective hard-sphere diameter would appear to be a preferable route for this thermodynamic property. A more refined state point dependent definition for the effective hard-sphere diameter is probably required for this property.

  1. Thin layer drying characteristics of curry leaves (Murraya koenigii in an indirect solar dryer

    Vijayan Selvaraj


    Full Text Available In this work, the thin layer drying characteristics of curry leaves (Murraya koenigii has been studied in an indirect forced convection solar dryer with constant air mass flow rate of 0.0636 kg/s. Twelve thin layer drying models were tested for its suitability to describe the drying characteristics of curry leaves. The dryer has reduced the initial moisture content of curry leaves from 67.3% (wet basis to the final moisture content of 4.75% (wet basis in 3.5 hours. The pickup efficiency of indirect solar dryer for drying curry leaves was varied between 4.9% and 23.02%. Based on the statistical parameters, the Modified Henderson and Pabis model and Wang and Singh model were selected for predicting the drying characteristics of curry leaves. The payback period for the solar dryer was evaluated as 8 months, which is found to be much lower when compared with the entire life span of 15 years. The payback evaluation confirms that the solar dryer is economically viable in rural applications.

    Full Text Available Annual estimates of the fish caught by local fishermen in randomly selected fishing villages adjacent to Gbedikere Lake were determined using Catch Assessment (CAS. The studies were carried out within two seasons of low water (February and high water (September periods between 2006 to 2008. Annual fish catch varied from 537.4 mts to 576.9 mts at high water. Mean catch per boat ranged from 7.40 kg to 10.60 kg among the landing sites. A total of 12 fish species were identified belonging to ten families. The catches were dominated by the cichlids with Orechromis niloticus dominating the overall catch compositions. Production estimate was compared with the catches obtained through experimental gill-net sampling and potential fish yield estimates using Ryder’s Morpho - Edaphic Index (MEI as modified by Henderson and Welcomme (1974. Contributions of the gears in use were also done with cast nets ranking above others (29%, followed by the set net (25%, hook and lines (16.6%, traps (16.6%, clap net (8.3%.

  3. Toward a unified model of passive drug permeation II: the physiochemical determinants of unbound tissue distribution with applications to the design of hepatoselective glucokinase activators.

    Ghosh, Avijit; Maurer, Tristan S; Litchfield, John; Varma, Manthema V; Rotter, Charles; Scialis, Renato; Feng, Bo; Tu, Meihua; Guimaraes, Cris R W; Scott, Dennis O


    In this work, we leverage a mathematical model of the underlying physiochemical properties of tissues and physicochemical properties of molecules to support the development of hepatoselective glucokinase activators. Passive distribution is modeled via a Fick-Nernst-Planck approach, using in vitro experimental data to estimate the permeability of both ionized and neutral species. The model accounts for pH and electrochemical potential across cellular membranes, ionization according to Henderson-Hasselbalch, passive permeation of the neutral species using Fick's law, and passive permeation of the ionized species using the Nernst-Planck equation. The mathematical model of the physiochemical system allows derivation of a single set of parameters governing the distribution of drug molecules across multiple conditions both in vitro and in vivo. A case study using this approach in the development of hepatoselective glucokinase activators via organic anion-transporting polypeptide-mediated hepatic uptake and impaired passive distribution to the pancreas is described. The results for these molecules indicate the permeability penalty of the ionized form is offset by its relative abundance, leading to passive pancreatic exclusion according to the Nernst-Planck extension of Fickian passive permeation. Generally, this model serves as a useful construct for drug discovery scientists to understand subcellular exposure of acids or bases using specific physiochemical properties.

  4. Effects of air temperature and velocity on the drying kinetics and product particle size of starch from arrowroot (Maranta arundinacae)

    Caparanga, Alvin R.; Reyes, Rachael Anne L.; Rivas, Reiner L.; De Vera, Flordeliza C.; Retnasamy, Vithyacharan; Aris, Hasnizah


    This study utilized the 3k factorial design with k as the two varying factors namely, temperature and air velocity. The effects of temperature and air velocity on the drying rate curves and on the average particle diameter of the arrowroot starch were investigated. Extracted arrowroot starch samples were dried based on the designed parameters until constant weight was obtained. The resulting initial moisture content of the arrowroot starch was 49.4%. Higher temperatures correspond to higher drying rates and faster drying time while air velocity effects were approximately negligible or had little effect. Drying rate is a function of temperature and time. The constant rate period was not observed for the drying rate of arrowroot starch. The drying curves were fitted against five mathematical models: Lewis, Page, Henderson and Pabis, Logarithmic and Midili. The Midili Model was the best fit for the experimental data since it yielded the highest R2 and the lowest RSME values for all runs. Scanning electron microscopy (SEM) was used for qualitative analysis and for determination of average particle diameter of the starch granules. The starch granules average particle diameter had a range of 12.06 - 24.60 μm. The use of ANOVA proved that particle diameters for each run varied significantly with each other. And, the Taguchi Design proved that high temperatures yield lower average particle diameter, while high air velocities yield higher average particle diameter.

  5. Plant uptake of bicarbonate as measured with the 11C isotope

    Wallace, A.; Mueller, R.T.; Wood, R.A.; Soufi, S.M.


    11 C which is cyclotron produced by 14 N(P, α) 11 C(half-life 20.1 M) was used as a tracer of bicarbonate to determine its movements from a nutrient solution through roots to stems and leaves of bush bean plants (Phaseolus vulgaris L. var Improved Tendergreen). The short time involved and the high solution pH minimized the need for use of the Henderson Hasselbach equation for activity correction. Quantities of 11 C did move into roots, stems and leaves with a sharp decreasing gradient (root/stem = 14.5, stems/leaves = 11.7) More 11 C moved into plants with KHCO 3 than with NaHCO 3 . The (NH 4 ) 2 SO 4 enhanced 11 C uptake and KNO 3 decreased it. This enhancement and competition indicated possibility of some uptake of HCO 3 - . In an experiment with Galenia pubescens (Eckl. and Zeyh.) Druce, the 11 C was more readily moved to stems and leaves than in bush bean indicating substantial uptake of HCO 3 - . (Auth.)

  6. Microwave blanching and drying characteristics of Centella asiatica (L.) urban leaves using tray and heat pump-assisted dehumidified drying.

    Trirattanapikul, W; Phoungchandang, S


    The appropriate stage of maturity of Centella asiatica (L.) Urban leaves was investigated. Mature leaves with large diameter contained high total phenolics and % inhibition. Microwave blanching for 30 s retained the highest total phenolics and the microwave blanching for 30 s and 45 s retained the highest % inhibition. Modified Henderson and Modified Chung-Pfost models showed the best fit to both fresh and blanched leaves for equilibrium moisture content, Xe = f(RHe, T) and equilibrium relative humidity, RHe = f(Xe, T), respectively. The Modified Page model was the most effective model in describing the leaf drying. All drying was in the falling rate period. The drying constant was related to drying air temperature using the Arrhenius model. Effective moisture diffusivities increased with increasing temperature and blanching treatments as well as dehumidification by heat pump-assisted dehumidified dryer. The heat pump-assited dehumidified drying incorporated by the microwave blanching could reduce the drying time at 40 °C by 31.2 % and increase % inhibition by 6.1 %. Quality evaluation by total phenolics, % inhibition and rehydration ratio showed the best quality for C. asiatica leaves pretreated by microwave blanching and dried at 40 °C in heat pump-assisted dehumidified dryer.

  7. Grapes (Vitis vinifera) drying by semitransparent photovoltaic module (SPVM) integrated solar dryer: an experimental study

    Tiwari, Sumit; Tiwari, G. N.


    In present research paper, semi-transparent photovoltaic module (SPVM) integrated greenhouse solar drying system has been used for grapes (Vitis vinifera) drying. Based on hourly experimental information namely solar intensity, moisture evaporated, ambient air temperature, grape surface temperatures, relative humidity and greenhouse air temperature etc. heat and mass transfer coefficient for the SPVM drying system have been evaluated. It has been seen that the convective heat transfer coefficients for grapes found between 3.1-0.84 W/m2 K. Also, there is a fair agreement between theoretical and practical mass transfer (moisture evaporated) during drying of grapes with a correlation coefficient (r) and root mean square percentage deviation (e) of 0.88 and 11.56 respectively. Further, nonlinear regression procedure has been used to fit various drying models namely Henderson and Pabis model, Newton's model, and Page's model. From the analysis, it was found that Page's model is best fitted for grapes drying in SPV greenhouse as well as open sun drying. Further, net electrical energy, thermal energy and equivalent thermal energy were found to be 3.61, 17.66 and 27.15 kWh during six days of drying respectively.

  8. Thermodynamic properties of diamond and wurtzite model fluids from computer simulation and thermodynamic perturbation theory

    Zhou, S.; Solana, J. R.


    Monte Carlo NVT simulations have been performed to obtain the thermodynamic and structural properties and perturbation coefficients up to third order in the inverse temperature expansion of the Helmholtz free energy of fluids with potential models proposed in the literature for diamond and wurtzite lattices. These data are used to analyze performance of a coupling parameter series expansion (CPSE). The main findings are summarized as follows, (1) The CPSE provides accurate predictions of the first three coefficient in the inverse temperature expansion of Helmholtz free energy for the potential models considered and the thermodynamic properties of these fluids are predicted more accurately when the CPSE is truncated at second or third order. (2) The Barker-Henderson (BH) recipe is appropriate for determining the effective hard sphere diameter for strongly repulsive potential cores, but its performance worsens with increasing the softness of the potential core. (3) For some thermodynamic properties the first-order CPSE works better for the diamond potential, whose tail is dominated by repulsive interactions, than for the potential, whose tail is dominated by attractive interactions. However, the first-order CPSE provides unsatisfactory results for the excess internal energy and constant-volume excess heat capacity for the two potential models.

  9. Drying kinetics and quality aspects during heat pump drying of onion (Allium cepa L.

    Nihar Ranjan Sahoo


    Full Text Available Normal 0 false false false MicrosoftInternetExplorer4 A prototype heat pump dryer has been developed for drying of fruits and vegetables at low temperature and relative humidity to maintain the quality of dried product. Onions, of Nasik red variety were peeled, trimmed and sliced to 2 mm thickness. The onion slices were dried in the heat pump dryer at 35ºC (32 % R.H., 40ºC (26 % R.H., 45ºC (19 % R.H. and 50ºC (15 % R.H.. Samples were also dried in a hot air dryer at 50ºC (52 % R.H. for comparison. The drying rate increased with increase in drying air temperature, associated with reduced R.H., in the heat pump dryer. Drying took place mainly under the falling rate period. The Page equation, resulting in a higher coefficient of determination and lower root mean square error, better described the thin-layer drying of onion slices than the Henderson and Pabis equation. Heat pump drying took less drying time of 360 min and yielded better quality dried product, with higher retention of ascorbic acid and pyruvic acid and lower colour change, as compared to a hot air dryer at the same drying air temperature of 50ºC.

    Full Text Available Shyness is considered as a universal phenomenon and its prevalence rates vary across cultures. This study aimed at comparing the level of shyness, self-construal, and personality traits of extraversion, introversion, neuroticism, and psychoticism among the college students from India, the host country, Africa; Iran; and Maldives, and Tibetan refugees in India (TRI, studying in different colleges at Mysore, India. Two hundred students (100 men and 100 women, age ranging from 17 to 30 years, were recruited based on stratified random sampling and were administered the Henderson/Zimbardo Shyness Questionnaire, Fernandez Scale of Independent–Interdependent Self-Construal, and Eysenck Personality Questionnaire–Revised. The results showed that shyness was significantly correlated with high introversion and high neuroticism scores. The results also showed that level of shyness varies significantly across different cultural groups and students from Maldives showed highest level of shyness whereas Iranian students had the lowest level of shyness. Although there was no significant gender difference, TRI males and Maldivian females had higher scores on shyness. Faith Orientation did not differentiate the prevalence of shyness among students of the different cultural groups. Shyness may be influenced by the culture from which one hails, and its level may vary depending on the nurturance.

    Full Text Available Basal stem rotting (BSR, caused by Fusarium spp., has been observed in peach palm (Bactris gasipaes Kunth. var. gasipaes Henderson plantations in Brazil since 2000. The disease is a limiting factor to peach palm farming, damaging plants of different ages. The pathogen presence has been verified in seeds. The objectives of this study were: to evaluate the sanitary and physiological quality of eight commercial lots of peach palm seeds from Porto Velho, state of Rondonia, in Brazil; to compare two detection methods for Fusarium spp. in peach palm seeds; to evaluate pathogenicity and to compare aggressiveness of Fusarium spp. isolates from peach palm seeds; and to evaluate the chemical treatment of two peach palm seed lots for controlling Fusarium spp., about their effects on: a sanitary effect; b germination and vigor. The Fusarium spp. pathogenic may be transmitted by seeds to seedlings causing BSR disease. The paperboard methodology for Fusarium spp. detection proved to be more efficient for recovering this pathogen in peach palm seeds. The Chlorothalonil + Thiophanate Methyl and Thiophanate Methyl fungicides achieved the effective control over the target pathogen Fusarium spp. in peach palm seeds. Fusarium oxysporum and Fusarium proliferatum isolated from seed and seedling, respectively, were pathogenic to peach palm.

    Alberto Barón C


    Full Text Available El balistocardiograma es el registro del movimiento del cuerpo que se origina por la energía transmitida desde el corazón hacia las grandes arterias como consecuencia de la salida de la sangre desde los ventrículos y del retroceso del cuerpo como reacción. Esta energía causa un desplazamiento del cuerpo en sentido cefálico, para luego cambiar en dirección opuesta cuando la sangre fluye por la aorta descendente. El sistema, que consta de tres partes, una tabla móvil en el sentido horizontal, un sistema de registro del movimiento corporal y un sistema de amplificación, permite generar un registro gráfico. La primera descripción corresponde a Gordon en 1877, cuando registró los movimientos horizontales y verticales de pacientes en una cama suspendida por cuatro cuerdas. En 1905 Yandel Henderson captó los movimientos en sentido horizontal, utilizando una tabla que se balanceaba unida a una serie de poleas; para el registro utilizó un quimógrafo. Pero fue Starr quien le dio el nombre al instrumento y elaboró un balistocardiógrafo indirecto en 1939, que inscribía las ondas en papel fotográfico. Pocos años después, Dock y Taubman diseñaron el primer balistocardiógrafo directo, usando unas barras metálicas ajustadas a las tibias del paciente. Henderson y Bixby mejoraron la precisión de la calibración a través de un microscopio. Autores como Hamilton, Dow, Thompson, Rappaport y Sprague describieron las ondas y su relación con los eventos del ciclo cardiaco. Su correlación con la fonocardiografía y el registro de los pulsos carotídeo, venoso y ápex-cardiograma fue de gran importancia para relacionar las ondas con los eventos fisiológicos. Starr demostró la relación de las ondas con el gasto cardiaco y su utilidad en el seguimiento de pacientes con insuficiencia cardiaca.

  13. Cosmic Evolution: The History of an Idea

    Dick, S. J.


    Cosmic evolution has become the conceptual framework within which modern astronomy is undertaken, and is the guiding principle of major NASA programs such as Origins and Astrobiology. While there are 19th- and early 20th century antecedents, as in the work of Robert Chambers, Herbert Spencer and Lawrence Henderson, it was only at mid-20th century that full-blown cosmic evolution began to be articulated and accepted as a research paradigm extending from the Big Bang to life, intelligence and the evolution of culture. Harlow Shapley was particularly important in spreading the idea to the public in the 1950s, and NASA embraced the idea in the 1970s as part of its SETI program and later its exobiology and astrobiology programs. Eric Chaisson, Carl Sagan and others were early proponents of cosmic evolution, and it continues to be elaborated in ever more subtle form as a research program and a philosophy. It has even been termed "Genesis for the 21st century." This paper documents the origin and development of the idea and offers a glimpse of where it could lead if cultural evolution is taken seriously, possibly leading to the concept of a postbiological universe.

  14. Cato Guldberg and Peter Waage, the history of the Law of Mass Action, and its relevance to clinical pharmacology.

    Ferner, Robin E; Aronson, Jeffrey K


    We have traced the historical link between the Law of Mass Action and clinical pharmacology. The Law evolved from the work of the French chemist Claude Louis Berthollet, was first formulated by Cato Guldberg and Peter Waage in 1864 and later clarified by the Dutch chemist Jacobus van 't Hoff in 1877. It has profoundly influenced our qualitative and quantitative understanding of a number of physiological and pharmacological phenomena. According to the Law of Mass Action, the velocity of a chemical reaction depends on the concentrations of the reactants. At equilibrium the concentrations of the chemicals involved bear a constant relation to each other, described by the equilibrium constant, K. The Law of Mass Action is relevant to various physiological and pharmacological concepts, including concentration-effect curves, dose-response curves, and ligand-receptor binding curves, all of which are important in describing the pharmacological actions of medications, the Langmuir adsorption isotherm, which describes the binding of medications to proteins, activation curves for transmembrane ion transport, enzyme inhibition and the Henderson-Hasselbalch equation, which describes the relation between pH, as a measure of acidity and the concentrations of the contributory acids and bases. Guldberg and Waage recognized the importance of dynamic equilibrium, while others failed to do so. Their ideas, over 150 years old, are embedded in and still relevant to clinical pharmacology. Here we explain the ideas and in a subsequent paper show how they are relevant to understanding adverse drug reactions. © 2015 The British Pharmacological Society.

  15. Conceptual model: possible changes of the seawater uranium isotopic composition through time

    Nowitzki, Hannah; Frank, Norbert; Fohlmeister, Jens [Universitaet Heidelberg (Germany)


    U behaves in seawater like a conservative element. More than 99% of the oceanic U content is {sup 238}U, whereas {sup 234}U is only present in trace amounts. As the residence time of U is significantly longer than the mixing time of the ocean, the ocean is well mixed with respect to U and its isotopic composition (Dunk 2002). Moreover, living corals incorporate U without isotopic fractionation. Therefore, the past seawater isotopic evolution of ({sup 234}U/{sup 238}U) can be accessed via U/Th age-dating of corals and the subsequent calculation of the initial ({sup 234}U/{sup 238}U) value. The isotopic ({sup 234}U/{sup 238}U) composition of seawater during the last 360 ka scatters around the modern seawater value (δ{sup 234}U ∼ (145±15) %, Henderson 2002). As these variations in the δ{sup 234}U value are rather small, a 'constant seawater isotopic composition hypothesis' is often used to validate U/Th ages of fossil corals. However, some authors find that the variability of the isotopic composition exceeds the expected range and suggest that it provides valuable information on variations in continental weathering and global run-off fluctuations or sea-level changes. This work will attempt to compare literature data of the seawater U isotopic composition to the results of a conceptual box-model of the oceanic U budget.

    Although diverse, theories of visual attention generally share the notion that attention is controlled by some combination of three distinct strategies: (1) exogenous cuing from locally contrasting primitive visual features, such as abrupt onsets or color singletons (e.g., L. Itti, C. Koch, & E. Neiber, 1998), (2) endogenous gain modulation of exogenous activations, used to guide attention to task-relevant features (e.g., V. Navalpakkam & L. Itti, 2007; J. Wolfe, 1994, 2007), and (3) endogenous prediction of likely locations of interest, based on task and scene gist (e.g., A. Torralba, A. Oliva, M. Castelhano, & J. Henderson, 2006). However, little work has been done to synthesize these disparate theories. In this work, we propose a unifying conceptualization in which attention is controlled along two dimensions: the degree of task focus and the contextual scale of operation. Previously proposed strategies-and their combinations-can be viewed as instances of this one mechanism. Thus, this theory serves not as a replacement for existing models but as a means of bringing them into a coherent framework. We present an implementation of this theory and demonstrate its applicability to a wide range of attentional phenomena. The model accounts for key results in visual search with synthetic images and makes reasonable predictions for human eye movements in search tasks involving real-world images. In addition, the theory offers an unusual perspective on attention that places a fundamental emphasis on the role of experience and task-related knowledge.

    Cervenka, L; Kubínová, J; Juszczak, L; Witczak, M


    Sorption isotherms of elecampe (Inula helenium L.) and burdock (Arctium lappa L.) root samples were obtained at 25 °C. Elecampe exhibited hysteresis loop in the range of 0.35-0.90 a(w) , whereas burdock roots showed significant differences between adsorption and desorption isotherms from 0.65 to 0.80 a(w) . Blahovec-Yanniotis was considered to give the best fit over the whole range of a(w) tested. Various parameters describing the properties of sorbed water derived from GAB, Henderson and Blahovec-Yanniotis models have been discussed. Differential scanning calorimetric method was used to measure the glass transition temperature (T (g)) of root samples in relation to water activity. The safe moisture content was determined in 12.01 and 14.96 g/100 g d. b. for burdock and elecampe root samples at 25 °C, respectively. Combining the T (g) line with sorption isotherm in one plot, it was found that the glass transition temperature concept overestimated the temperature stability for both root samples.

  18. Design and Performance Evaluation of a Solar Assisted Heat Pump Dryer Integrated with Biomass Furnace for Red Chilli

    M. Yahya


    Full Text Available The performance of a solar assisted heat pump dryer integrated with biomass furnace has been designed and evaluated for drying red chillies, and drying kinetics of red chillies were evaluated. The red chillies were dried from 22 kg with moisture content of 4.26 db to moisture content of 0.08 db which needed 11 hours, with the average drying chamber temperature, drying chamber relative humidity, and an air mass flow rate of 70.5°C, 10.1%, and 0.124 kg/s, respectively, while the open sun drying needed 62 hours. Compared to open sun drying, this dryer yielded 82% saving in drying time. The drying rate, the specific moisture extraction rate, and thermal efficiency of the dryer were estimated in average to be about 1.57 kg/h, 0.14 kg/kWh, and 9.03%, respectively. Three mathematical models, the Newton, Henderson-Pabis, and Page models, were fitted to the experimental data on red chillies dried by solar assisted heat pump dryer integrated with biomass furnace and open sun drying. The performance of these models was evaluated by comparing the coefficient of determination (R2, mean bias error (MBE, and root mean-square error (RMSE. The Page model gave the best results for representing drying kinetics of red chillies.

  19. Grapes ( Vitis vinifera) drying by semitransparent photovoltaic module (SPVM) integrated solar dryer: an experimental study

    Tiwari, Sumit; Tiwari, G. N.


    In present research paper, semi-transparent photovoltaic module (SPVM) integrated greenhouse solar drying system has been used for grapes ( Vitis vinifera) drying. Based on hourly experimental information namely solar intensity, moisture evaporated, ambient air temperature, grape surface temperatures, relative humidity and greenhouse air temperature etc. heat and mass transfer coefficient for the SPVM drying system have been evaluated. It has been seen that the convective heat transfer coefficients for grapes found between 3.1-0.84 W/m2 K. Also, there is a fair agreement between theoretical and practical mass transfer (moisture evaporated) during drying of grapes with a correlation coefficient (r) and root mean square percentage deviation (e) of 0.88 and 11.56 respectively. Further, nonlinear regression procedure has been used to fit various drying models namely Henderson and Pabis model, Newton's model, and Page's model. From the analysis, it was found that Page's model is best fitted for grapes drying in SPV greenhouse as well as open sun drying. Further, net electrical energy, thermal energy and equivalent thermal energy were found to be 3.61, 17.66 and 27.15 kWh during six days of drying respectively.

    Full Text Available The shelf life estimating of instant cassava were determined by analyzing the moisture sorption of it. The instant cassava was made into cube form with dimension of 0,5 cm x 0,5 cm x 0,5 cm and used as samples to analyzing the moisture sorption isotherm characteristic. Moisture sorption isotherms of it were determined at 28±2°C using standard gravimetric static method over a range of equilibrium relative humidity (ERH from 6.90%-97.90%. The experimental data were fitted by Henderson model and well predicted almost at each point of aw. The data of instant cassava’s moisture sorption isotherm followed type II behavior. The shelf life of it were calculated using Labuza equation with three different packaging materials: low density polyethylene (LDPE of 0.03 mm thickness, polypropylene (PP of 0.03 mm thickness and retort pouch. The shelf life of instant cassava using those three packaging materials were obtained for 103, 88 and 3502 days, respectively.

  1. Hypothesis: the regulation of the partial pressure of oxygen by the serotonergic nervous system in hypoxia.

    Devereux, Diana; Ikomi-Kumm, Julie


    The regulation of the partial pressure of oxygen by the serotonergic nervous system in hypoxia is a hypothesis, which proposes an inherent operative system in homo sapiens that allows central nervous system and endocrine-mediated vascular system adaption to variables in partial pressure of oxygen, pH and body composition, while maintaining sufficient oxygen saturation for the immune system and ensuring protection of major organs in hypoxic and suboptimal conditions. While acknowledging the importance of the Henderson-Hasselbalch equation in the regulation of acid base balance, the hypothesis seeks to define the specific neuroendocrine/vascular mechanisms at work in regulating acid base balance in hypoxia and infection. The SIA (serotonin-immune-adrenergic) system is proposed as a working model, which allows central nervous system and endocrine-mediated macro- and micro vascular 'fine tuning'. The neurotransmitter serotonin serves as a 'hypoxic sensor' in concert with other operators to orchestrate homeostatic balance in normal and pathological states. The SIA system finely regulates oxygen, fuel and metabolic buffering systems at local sites to ensure optimum conditions for the immune response. The SIA system is fragile and its operation may be affected by infection, stress, diet, environmental toxins and lack of exercise. The hypothesis provides new insight in the area of neuro-gastroenterology, and emphasizes the importance of diet and nutrition as a complement in the treatment of infection, as well as the normalization of intestinal flora following antibiotic therapy.

  2. Water adsorption isotherms and thermodynamic properties of cassava bagasse

    Polachini, Tiago Carregari; Betiol, Lilian Fachin Leonardo; Lopes-Filho, José Francisco; Telis-Romero, Javier


    Highlights: • Adsorption isotherms and composition of cassava bagasse were determined. • GAB equation was the best-fitted model to sorption data of type II isotherm. • Isosteric heat of sorption was calculated in a range of equilibrium moisture content. • Differential enthalpy and entropy confirmed the isokinetic compensation theory. • Water adsorption by cassava bagasse is considered an enthalpy driven process. - Abstract: Losses of food industry are generally wet products that must be dried to posterior use and storage. In order to optimize drying processes, the study of isotherms and thermodynamic properties become essential to understand the water sorption mechanisms of cassava bagasse. For this, cassava bagasse was chemically analyzed and had its adsorption isotherms determined in the range of 293.15–353.15 K through the static gravimetric method. The models of GAB, Halsey, Henderson, Oswin and Peleg were fitted, and best adjustments were found for GAB model with R"2 > 0.998 and no pattern distribution of residual plots. Isosteric heat of adsorption and thermodynamic parameters could be determined as a function of moisture content. Compensation theory was confirmed, with linear relationship between enthalpy and entropy and higher values of isokinetic temperature (T_B = 395.62 K) than harmonic temperature. Water adsorption was considered driven by enthalpy, clarifying the mechanisms of water vapor sorption in cassava bagasse.

  3. Forest Vegetation Monitoring Protocol for National Parks in the North Coast and Cascades Network

    Woodward, Andrea; Hutten, Karen M.; Boetsch, John R.; Acker, Steven A.; Rochefort, Regina M.; Bivin, Mignonne M.; Kurth, Laurie L.


    Plant communities are the foundation for terrestrial trophic webs and animal habitat, and their structure and species composition are an integrated result of biological and physical drivers (Gates, 1993). Additionally, they have a major role in geologic, geomorphologic and soil development processes (Jenny, 1941; Stevens and Walker, 1970). Throughout most of the Pacific Northwest, environmental conditions support coniferous forests as the dominant vegetation type. In the face of anthropogenic climate change, forests have a global role as potential sinks for atmospheric carbon (Goodale and others, 2002). Consequently, knowledge of the status of forests in the three large parks of the NCCN [that is, Mount Rainier (MORA), North Cascades (NOCA), and Olympic (OLYM) National Parks] is fundamental to understanding the condition of Pacific Northwest ecosystems. Diverse climate and soil properties across the Pacific Northwest result in a variety of forest types (Franklin and Dyrness, 1973; Franklin and others, 1988; Henderson and others, 1989, 1992). The mountainous terrain of Mount Rainier, North Cascades, and Olympic National Parks create steep elevational and precipitation gradients within and among the parks: collectively, these parks span from sea level to more than 4,200 m; and include areas with precipitation from 90 to more than 500 cm. The resulting forests range from coastal rainforests with dense understories and massive trees draped with epiphytes; to areas with drought-adapted Ponderosa pines; to high-elevation subalpine fir forests interspersed with meadows just below treeline (table 1). These forests, in turn, are the foundation for other biotic communities constituting Pacific Northwest ecosystems.

  4. pKa-critical Interpretations of Solubility–pH Profiles: PG 300995 and NSC-639829 Case Studies

    George Butcher


    Full Text Available Two weak bases, PG-300995 (anti-HIV agent and NSC-639829 (anti-tumor agent, whose log S – pH profiles had been previously published, but whose pKa values had not been reported, were analyzed using a method which can determine pKa values from log S – pH data. This “SpH-pKa” technique, although often practiced, can result in inaccurate pKa values, for a variety of reasons. The operational SpH-pKa values were compared to those predicted by MarvinSketch (ChemAxon, ADMET Predictor (Simulation Plus, and ACD/Percepta (ACD/Labs. The agreement for the sparingly-soluble PG-300995 was reasonably good. However, a substantial difference was found for the practically-insoluble NSC-639829. To probe this further, the pKa of NSC‑639829 was measured by an independent spectrophotometric cosolvent technique. The log S - pH profile of NSC-639829 was then re‑analyzed with the independently-measured pKa. It was found that the equilibrium model which best fit the solubility data is consistent with the presence of a monocationic NSC-639829 dimeric species below pH 4. This illustrates that an independently-determined accurate pKa is critical to mechanistic interpretations of solubility-pH data. Apparently, the Henderson-Hasselbalch equation holds for PG-300995, but not NSC-639829.

  8. [Jealousy between siblings in early childhood. Nursing assessment based on a case study].

    Puig-Plana, María Pilar


    Childhood jealousy, when a little brother or sister is born, has always been a subject treated within the family environment. Parent's attitude in their interaction with their offspring may increase the response of the jealous child. The emotional expressions of the jealous child may lead to behaviour changes, that may occasionally put the physical integrity of the newborn at risk, since it is the most vulnerable in the family group. In view of the above mentioned, a case of a three-year-old child living with his parents and his nine-month-old sister, is presented. The child shows characteristic behaviour changes of jealousy, such as, rebelliousness, aggressiveness and hyperactivity. The brother's psychomotor discomfort leads to a proneness to accidents for the baby girl and the obvious parental concern. For these reasons nursing intervention in the family group was proposed, based on the theoretical Virginia Henderson Needs Model. The actions will come from the older brother and parents. The aim of the nursing intervention is to lead the behaviour changes in order to re-establish a safe and healthy family environment. Copyright 2009 Elsevier España, S.L. All rights reserved.

  9. Alliances in Human Biology: The Harvard Committee on Industrial Physiology, 1929-1939.

    Oakes, Jason


    In 1929 the newly-reorganized Rockefeller Foundation funded the work of a cross-disciplinary group at Harvard University called the Committee on Industrial Physiology (CIP). The committee's research and pedagogical work was oriented towards different things for different members of the alliance. The CIP program included a research component in the Harvard Fatigue Laboratory and Elton May's interpretation of the Hawthorne Studies; a pedagogical aspect as part of Wallace Donham's curriculum for Harvard Business School; and Lawrence Henderson's work with the Harvard Pareto Circle, his course Sociology 23, and the Harvard Society of Fellows. The key actors within the CIP alliance shared a concern with training men for elite careers in government service, business leadership, and academic prominence. But the first communications between the CIP and the Rockefeller Foundation did not emphasize training in human biology. Instead, the CIP presented itself as a coordinating body that would be able to organize all the varied work going on at Harvard that did not fit easily into one department, and it was on this basis that the CIP became legible to the President of Harvard, A. Lawrence Lowell, and to Rockefeller's Division of Social Sciences. The members of the CIP alliance used the term human biology for this project of research, training and institutional coordination.

  10. Isotherms and isosteric heat of sorption of two varieties of Peruvian quinoa

    Augusto Pumacahua-Ramos


    Full Text Available The isosteric heats of sorption of two varieties of quinoa (Chenopodium quinoaWilld. grain were determined by the static gravimetric method at four temperatures (40, 50, 60 and 70 °C andin relative humidity environments provided by six saturated salt solutions. Six mathematical equations were used to model the experimental data: GAB, Oswin, Henderson, Peleg, Smith and Halsey. The isosteric heat of sorption was determined using the parameters of the GAB model. All the equations were shown to be appropriate by the coefficients of determination (R2 and the mean absolute error (MA%E. The influence of temperature was observed because the adsorption of water by the grains was lower at highertemperatures. The equilibrium moisture contents for security of storage, for long periods of time at water activity lower than 0.65, were 12 -13%. The effect of temperature on the parameters of the GAB model was analysed using the exponential Arrhenius equation. The isosteric heats of sorption were determined by applying the Clausius-Clapeyron equation as a function of humidity. The isosteric heat at 5% moisture for grains of the Blanca de Juli variety was 3663 kJ/kg and for the Pasankalla variety it was 3393 kJ/kg. The experimental data for isosteric heat as a function of humidity were satisfactorily modelled using three mathematical equations.

  11. Prioritizing islands for the eradication of invasive vertebrates in the United Kingdom overseas territories.

    Dawson, Jeffrey; Oppel, Steffen; Cuthbert, Richard J; Holmes, Nick; Bird, Jeremy P; Butchart, Stuart H M; Spatz, Dena R; Tershy, Bernie


    Invasive alien species are one of the primary threats to native biodiversity on islands worldwide. Consequently, eradicating invasive species from islands has become a mainstream conservation practice. Deciding which islands have the highest priority for eradication is of strategic importance to allocate limited resources to achieve maximum conservation benefit. Previous island prioritizations focused either on a narrow set of native species or on a small geographic area. We devised a prioritization approach that incorporates all threatened native terrestrial vertebrates and all invasive terrestrial vertebrates occurring on 11 U.K. overseas territories, which comprise over 2000 islands ranging from the sub-Antarctic to the tropics. Our approach includes eradication feasibility and distinguishes between the potential and realistic conservation value of an eradication, which reflects the benefit that would accrue following eradication of either all invasive species or only those species for which eradication techniques currently exist. We identified the top 25 priority islands for invasive species eradication that together would benefit extant populations of 155 native species including 45 globally threatened species. The 5 most valuable islands included the 2 World Heritage islands Gough (South Atlantic) and Henderson (South Pacific) that feature unique seabird colonies, and Anegada, Little Cayman, and Guana Island in the Caribbean that feature a unique reptile fauna. This prioritization can be rapidly repeated if new information or techniques become available, and the approach could be replicated elsewhere in the world. © 2014 Crown copyright.

  12. Effect of the reference solution in the measurement of ion activity coefficients using cells with transference at T = 298.15 K

    Lladosa, Estela; Arce, Alberto; Wilczek-Vera, Grazyna; Vera, Juan H.


    This work reports individual activity coefficients of ions at T = 298.15 K in aqueous solutions obtained from voltage values of the respective half-cell ion-selective-electrode and a single-junction Ag-AgCl reference electrode, filled with different reference solutions at different concentrations. For potassium and chloride ions in KCl aqueous solutions, reference solutions of KCl, NaCl, or CsCl were used. For sodium and chloride ions in aqueous NaCl solutions, reference solutions of CsCl were used. Experimental runs were performed at molalities (1, 2, and 3) m of the reference solution. The concentration of the sample solution was increased, starting from around 1 . 10 -3 m, up to the molality of the reference solution. The values of activity coefficients are calculated using the Henderson equation to estimate the liquid-junction potential. Results show that the ionic activity coefficients are independent of the nature and concentration of reference solution.

The resultsof research are advisablefor use indevelop of functional food ingredient which is used pectin as a gelling agent and a stabilizer.

  14. Calculation of the mean force constants of the rare gases and the rectilinear law of mean force

    Lee, M.W.; Bigeleisen, J.


    The mean energies, (U), and the mean force constants, (nabla 2 U), have been calculated for liquid argon and liquid krypton using the WCA perturbation theory, and for gaseous argon and krypton along the coexistence line by solution of the PY equation for the radial distribution function. Calculations have been made for the Lennard-Jones, Barker-Henderson, and Maitland-Smith potentials. There is little difference in the values of (U) and (nabla 2 U) calculated for the three potentials. The calculated values are in good agreement with experimental data. Correlation of the calculated values of (nabla 2 U) for the liquid and gas leads to an empirical relationship between (nabla 2 U) and the density of the phase along the coexistence line. When the latter is combined with the law of rectilinear diameters of the density, the rectilinear law of mean force is obtained, which is in good agreement with experimental data on argon. It is shown that the scaling exponent for the mean force constant, (nabla 2 U)/sub l/-(nabla 2 U)/sub g/, is larger than the scaling exponent of the density below the critical temperature and becomes equal to it at the critical temperature. The rationale for the rectilinear law of mean force is provided by an expansion of the radial distribution function of the liquid in powers of the density and the use of the WCA approximation to the radial distribution function

  15. Plant productivity and characterization of zeoponic substrates after three successive crops of radish

    Gruener, J. E.; Ming, Doug; Galindo, C., Jr.; Henderson, K. E.


    The National Aeronautics and Space Administration (NASA) has developed advanced life support (ALS) systems for long duration space missions that incorporate plants to regenerate the atmosphere (CO2 to O2), recycle water (via evapotranspiration), and produce food. NASA has also developed a zeolite-based synthetic substrate consisting of clinoptilolite and synthetic apatite to support plant growth for ALS systems (Ming et al., 1995). The substrate is called zeoponics and has been designed to slowly release all plant essential elements into "soil" solution. The substrate consists of K- and NH4-exchanged clinoptilolite and a synthetic hydroxyapatite that has Mg, S, and the plant-essential micronutrients incorporated into its structure in addition to Ca and P. Plant performance in zeoponic substrates has been improved by the addition of dolomite pH buffers, nitrifying bacteria, and other calcium-bearing minerals (Henderson et al., 2000; Gruener et al., 2003). Wheat was used as the test crop for all of these studies. The objectives of this study were to expand upon the previous studies to determine the growth and nutrient uptake of radish in zeoponic substrates and to determine the nutrient availability of the zeoponic substrate after three successive radish crops.

  16. Perturbation theories for the dipolar fluids

    Lee, L.L.; Chung, T.H.


    We derive here four different perturbation equations for the calculation of the angular pair correlation functions of dipolar fluids; namely, the first order y-expansion, the modified Percus--Yevik (MPY) expansion, the modified hypernetted chain (MHNC) expansion, and the modified linearized hypernetted chain (MLHNC) equation. Both the method of the functional expansion and the method of the cluster integrals are utilized. Comparison with other perturbation theories (e.g., the Melnyk--Smith equation) is made. While none of the theories is exact, as shown by the cluster diagrams, the MLHNC and the MHNC contain more diagrams than, say, the MPY and y-expansion. The y-expansion equation can be improved by including the correction terms to the Kirkwood superposition approximation for the triplet correlation function. For example, the inclusion of the correction term rho∫d4h(14)h(24)h(34) in a formula given by Henderson, is shown to improve substantially the y-expansion equation. We examine the performance of two of the theories: the y-expansion and the MLHNC equation for a Stockmayer (dipolar) fluid with a reduced dipole moment μ/sup asterisk2/ [ = μ 2 /(epsilonsigma 3 )] = 1.0. Comparison with Monte Carlo simulation results of Adams et al. and with other theories (e.g., the QHNC equation) shows that our results are reasonable. Further improvements of the equations are also pointed out

  17. Bayesian inference on genetic merit under uncertain paternity

    Tempelman Robert J


    Full Text Available Abstract A hierarchical animal model was developed for inference on genetic merit of livestock with uncertain paternity. Fully conditional posterior distributions for fixed and genetic effects, variance components, sire assignments and their probabilities are derived to facilitate a Bayesian inference strategy using MCMC methods. We compared this model to a model based on the Henderson average numerator relationship (ANRM in a simulation study with 10 replicated datasets generated for each of two traits. Trait 1 had a medium heritability (h2 for each of direct and maternal genetic effects whereas Trait 2 had a high h2 attributable only to direct effects. The average posterior probabilities inferred on the true sire were between 1 and 10% larger than the corresponding priors (the inverse of the number of candidate sires in a mating pasture for Trait 1 and between 4 and 13% larger than the corresponding priors for Trait 2. The predicted additive and maternal genetic effects were very similar using both models; however, model choice criteria (Pseudo Bayes Factor and Deviance Information Criterion decisively favored the proposed hierarchical model over the ANRM model.

  18. [Nursing knowledge: the evolution of scientific philosophies and paradigm trends].

    Hung, Hsuan-Man; Wang, Hui-Ling; Chang, Yun-Hsuan; Chen, Chung-Hey


    Different aspects of philosophy are derived from different paradigms that contain various main points, some of which are repeated or overlap. Belief and practice are two components of a paradigm that provide perspective and framework and lead to nursing research. Changes in healthcare have popularized empirical and evidence-based research in the field of nursing research. However, the evidence-base study approach has given rise to a certain level of debate. Until now, no standard paradigm has been established for the nursing field, as different professionals use different paradigms in their studies. Such provides certain limitations as well as advantages. The quantitative aspects of a nursing paradigm were developed by Peplau and Henderson (1950) and Orem (1980). Such remained the standard until 1990, when Guba and Parse proposed qualitative viewpoints in contextual features. Therefore, the nursing paradigm has made great contributions to the development of knowledge in nursing care, although debate continues due to incomplete knowledge attributable to the presentation of knowledge and insight within individually developed paradigms. It is better to apply multiple paradigms to different research questions. It is suggested that better communication amongst experts regarding their individual points of view would help nursing members to integrate findings within the global pool of knowledge and allow replication over multiple studies.

  19. Solubility-pH profiles of some acidic, basic and amphoteric drugs.

    Shoghi, Elham; Fuguet, Elisabet; Bosch, Elisabeth; Ràfols, Clara


    The solubility vs. pH profiles of five ionizable drugs of different nature (a monoprotic acid, a monoprotic base, a diprotic base and two amphoteric compounds showing a zwitterionic species each one) have been determined through two different methodologies: the classical shake-flask (S-F) and the potentiometric Cheqsol methods using in both instances the appropriate Henderson-Hasselbalch (H-H) or derived relationships. The results obtained independently from both approaches are consistent. A critical revision about the influence of the electrolyte used as buffering agent in the S-F method on the obtained solubility values is also performed. Thus, some deviations of the experimental points with respect the H-H profiles can be attributed to specific interactions between the buffering electrolyte and the drug due to the hydrotrophic character of citric and lactic acids. In other cases, the observed deviations are independent of the buffers used since they are caused by the formation of new species such as drug aggregates (cefadroxil) or the precipitation of a salt from a cationic species of the analyzed compound (quetiapine).

Screening mammography has been shown to be effective in reducing breast cancer mortality in women aged 50–74 years but not among those aged 75 years or older. Given the large heterogeneity in comorbidity status and life expectancy among older women, controversy remains over screening mammography in this population. Diminished life expectancy with aging may decrease the potential screening benefit and increase the risk of harms. In this review, we summarize the evidence on screening mammography utilization, performance, and outcomes and highlight evidence gaps. Optimizing the screening strategy will involve separating older women who will benefit from screening from those who will not benefit by using information on comorbidity status and life expectancy. This review has identified areas related to screening mammography in older women that warrant additional research, including the need to evaluate emerging screening technologies, such as tomosynthesis among older women and precision cancer screening. In the absence of randomized controlled trials, the benefits and harms of continued screening mammography in older women need to be estimated using both population-based cohort data and simulation models.
