  1. The definition of kernel Oz

    OpenAIRE

    Smolka, Gert

    1994-01-01

    Oz is a concurrent language providing for functional, object-oriented, and constraint programming. This paper defines Kernel Oz, a semantically complete sublanguage of Oz. It was an important design requirement that Oz be definable by reduction to a lean kernel language. The definition of Kernel Oz introduces three essential abstractions: the Oz universe, the Oz calculus, and the actor model. The Oz universe is a first-order structure defining the values and constraints Oz computes with. The ...

    to contribute to a better understanding of these objects by studying SN 2006oz, a newly-recognized member of this class. Methods. We present multi-color light curves of SN 2006oz from the SDSS-II SN Survey that cover its rise time, as well as an optical spectrum that shows that the explosion occurred at z ~ 0.......376. We fitted black-body functions to estimate the temperature and radius evolution of the photosphere and used the parametrized code SYNOW to model the spectrum. We constructed a bolometric light curve and compared it with explosion models. In addition, we conducted a deep search for the host galaxy...... to a recombination wave in a circumstellar medium (CSM) and discuss whether this is a common property of all similar explosions. The subsequent rise can be equally well described by input from a magnetar or by ejecta-CSM interaction, but the models are not well constrained owing to the lack of post...

    Mullins, James; Fielding, Mick; Nahavandi, Saeid

    2009-05-01

    This paper reports on robotic and haptic technologies and capabilities developed for the law enforcement and defence community within Australia by the Centre for Intelligent Systems Research (CISR). The OzBot series of small and medium surveillance robots have been designed in Australia and evaluated by law enforcement and defence personnel to determine suitability and ruggedness in a variety of environments. Using custom developed digital electronics and featuring expandable data busses including RS485, I2C, RS232, video and Ethernet, the robots can be directly connected to many off the shelf payloads such as gas sensors, x-ray sources and camera systems including thermal and night vision. Differentiating the OzBot platform from its peers is its ability to be integrated directly with haptic technology or the 'haptic bubble' developed by CISR. Haptic interfaces allow an operator to physically 'feel' remote environments through position-force control and experience realistic force feedback. By adding the capability to remotely grasp an object, feel its weight, texture and other physical properties in real-time from the remote ground control unit, an operator's situational awareness is greatly improved through Haptic augmentation in an environment where remote-system feedback is often limited.

  7. OzFlux data: network integration from collection to curation

    2017-06-01

    Full Text Available Measurement of the exchange of energy and mass between the surface and the atmospheric boundary-layer by the eddy covariance technique has undergone great change in the last 2 decades. Early studies of these exchanges were confined to brief field campaigns in carefully controlled conditions followed by months of data analysis. Current practice is to run tower-based eddy covariance systems continuously over several years due to the need for continuous monitoring as part of a global effort to develop local-, regional-, continental- and global-scale budgets of carbon, water and energy. Efficient methods of processing the increased quantities of data are needed to maximise the time available for analysis and interpretation. Standardised methods are needed to remove differences in data processing as possible contributors to observed spatial variability. Furthermore, public availability of these data sets assists with undertaking global research efforts. The OzFlux data path has been developed (i to provide a standard set of quality control and post-processing tools across the network, thereby facilitating inter-site integration and spatial comparisons; (ii to increase the time available to researchers for analysis and interpretation by reducing the time spent collecting and processing data; (iii to propagate both data and metadata to the final product; and (iv to facilitate the use of the OzFlux data by adopting a standard file format and making the data available from web-based portals. Discovery of the OzFlux data set is facilitated through incorporation in FLUXNET data syntheses and the publication of collection metadata via the RIF-CS format. This paper serves two purposes. The first is to describe the data sets, along with their quality control and post-processing, for the other papers of this Special Issue. The second is to provide an example of one solution to the data collection and curation challenges that are encountered by similar flux

  8. Comparative Analysis of Conventional Electronic and OZ Concept Displays for Aircraft Energy Management

    Science.gov (United States)

    Baker, Erik Reese

    A repeated-measures, within-subjects design was conducted on 58 participant pilots to assess mean differences on energy management situation awareness response time and response accuracy between a conventional electronic aircraft display, a primary flight display (PFD), and an ecological interface design aircraft display, the OZ concept display. Participants were associated with a small Midwestern aviation university, including student pilots, flight instructors, and faculty with piloting experience. Testing consisted of observing 15 static screenshots of each cockpit display type and then selecting applicable responses from 27 standardized responses for each screen. A paired samples t-test was computed comparing accuracy and response time for the two displays. There was no significant difference in means between PFD Response Time and OZ Response Time. On average, mean PFD Accuracy was significantly higher than mean OZ Accuracy (MDiff = 13.17, SDDiff = 20.96), t(57) = 4.78, p performance differences were not operationally remarkable. There was no significant correlation between PFD Response Time and PFD Accuracy, but there was a significant correlation between OZ Response Time and OZ Accuracy, r (58) = .353, p performing as well as experienced professional pilots on dynamic flight tasks with the OZ display. A demographic questionnaire and a feedback survey were included in the trial. An equivalent three-quarters majority of participants rated the PFD as "easy" and the OZ as "confusing", yet performance accuracy and response times between the two displays were not operationally different.

    We present results for the first three years of OzDES, a six-year program to obtain redshifts for objects in the Dark Energy Survey (DES) supernova fields using the 2dF fibre positioner and AAOmega spectrograph on the Anglo-Australian Telescope. OzDES is a multi-object spectroscopic survey targeting multiple types of targets at multiple epochs over a multi-year baseline, and is one of the first multi-object spectroscopic surveys to dynamically include transients into the target list soon after their discovery. At the end of three years, OzDES has spectroscopically confirmed almost 100 supernovae, and has measured redshifts for 17,000 objects, including the redshifts of 2,566 supernova hosts. We examine how our ability to measure redshifts for targets of various types depends on signal-to-noise, magnitude, and exposure time, finding that our redshift success rate increases significantly at a signal-to-noise of 2 to 3 per 1-A° ngstrom bin. We also find that the change in signal-to-noise with exposure time closely matches the Poisson limit for stacked exposures as long as 10 hours.We use these results to predict the redshift yield of the full OzDES survey, as well as the potential yields of future surveys on other facilities such as 4MOST, PFS, and MSE. This work marks the first OzDES data release, comprising 15,327 redshifts. OzDES is on target to obtain over 30,000 redshifts over the six-year duration of the survey, including a yield of approximately 5,700 supernova host-galaxy redshifts.

    OzFlux is the regional Australian and New Zealand flux tower network that aims to provide a continental-scale national research facility to monitor and assess trends, and improve predictions, of Australia's terrestrial biosphere and climate. This paper describes the evolution, design, and current status of OzFlux as well as provides an overview of data processing. We analyse measurements from all sites within the Australian portion of the OzFlux network and two sites from New Zealand. The response of the Australian biomes to climate was largely consistent with global studies except that Australian systems had a lower ecosystem water-use efficiency. Australian semi-arid/arid ecosystems are important because of their huge extent (70 %) and they have evolved with common moisture limitations. We also found that Australian ecosystems had a similar radiation-use efficiency per unit leaf area compared to global values that indicates a convergence toward a similar biochemical efficiency. The two New Zealand sites represented extremes in productivity for a moist temperate climate zone, with the grazed dairy farm site having the highest GPP of any OzFlux site (2620 gC m-2 yr-1) and the natural raised peat bog site having a very low GPP (820 gC m-2 yr-1). The paper discusses the utility of the flux data and the synergies between flux, remote sensing, and modelling. Lastly, the paper looks ahead at the future direction of the network and concludes that there has been a substantial contribution by OzFlux, and considerable opportunities remain to further advance our understanding of ecosystem response to disturbances, including drought, fire, land-use and land-cover change, land management, and climate change, which are relevant both nationally and internationally. It is suggested that a synergistic approach is required to address all of the spatial, ecological, human, and cultural challenges of managing the delicately balanced ecosystems in Australasia.

    This paper focuses on a recent gesture by the Spanish novelist and public intellectual Antonio Muñoz Molina to publicly recuperate Aub’s testimony of uprootedness in France, Algeria, and Mexico, a gesture that relies on the concept of cosmopolitan memory as it has been developed in Holocaust studies. I critique Muñoz Molina’s use of the Holocaust as a template for a transnational cultural history based on a supposedly shared Jewish past. Muñoz Molina generalizes on two levels: he turns Aub in...

    2015-12-01

    Full Text Available Oscar Muñoz's work revolves around the question of the specificity of photography. By doing so, it redirects a current trend of visual studies that are fascinated with the non-specificity of the objects and the itinerancy of languages. Muñoz wonders what lies at the heart of photography. Is it the mechanical reproduction or the ability to chemically fix the image? Is it the power to isolate the instant or to perpetuate anything captured by the machine? The transformation that introduces photography has less to do with the work itself and more with the experience of image. That experience is, first of all, an experience of time since the image produces an intermediate time between proliferation and what is left as a remain.

  18. The Case of Dr. Oz: Ethics, Evidence, and Does Professional Self-Regulation Work?

    2017-02-01

    Dr. Mehmet Oz is widely known not just as a successful media personality donning the title "America's Doctor ® ," but, we suggest, also as a physician visibly out of step with his profession. A recent, unsuccessful attempt to censure Dr. Oz raises the issue of whether the medical profession can effectively self-regulate at all. It also raises concern that the medical profession's self-regulation might be selectively activated, perhaps only when the subject of professional censure has achieved a level of public visibility. We argue here that the medical profession must look at itself with a healthy dose of self-doubt about whether it has sufficient knowledge of or handle on the less visible Dr. "Ozes" quietly operating under the profession's presumptive endorsement. © 2017 American Medical Association.

  20. MARS-OZ - A Design for a Simulated Mars Base in the Australian Outback

    Science.gov (United States)

    Willson, D.; Clarke, J. D. A.; Murphy, G.

    Mars Society Australia has developed the design of a simulated Mars base, MARS-OZ, for deployment in outback Australia. MARS-OZ will provide a platform for a diverse range of Mars analogue research in Australia. The simulated base consists of two mobile modules whose dimensions and shape approximate those of horizontally landed bent biconic spacecraft described in an earlier paper. The modules are designed to support field engineering, robotics, architectural, geological, biological and human factors research at varying levels of simulation fidelity. Non-Mars related research can also be accommodated, for example general field geology and biology, and engineering research associated with sustainable, low impact architecture. Crews of up to eight can be accommodated. In addition to its research function, the base also will serve as a centre of space education and outreach activities. The prime site for the MARS-OZ simulated base is located in the northern Flinders Ranges near Arkaroola in South Australia. This region contains many features that provide useful scientific analogues to known or possible past and present conditions on Mars from both a geological and biological perspective. The features will provide a wealth of study opportunities for crews. The very diverse terrain and regolith materials will provide ideal opportunities to field trial a range of equipment, sensors and exploration strategies. If needed, the prime site can be secured from casual visitors, allowing research into human interaction in isolation. Despite its relative isolation, the site is readily accessible by road and air from major Australian centres. This paper provides description of the configuration, design and construction of the proposed facility, its interior layout, equipment and systems fitouts, a detailed cost estimate, and its deployment. We estimate that the deployment of MARS-OZ could occur within nine months of securing funding.

    Full Text Available Antonio Muñoz Molina (Úbeda, 1956 es ya, sin lugar a dudas, uno de los más destacados novelistas españoles contemporáneos. boga en la década que va de 1960 a 1970 al “realismo depurado” y al compromiso ético. La narrativa de Muñoz Molina apela constantemente a los cruces de códigos y al hacerlo va adoptando singulares modulaciones; itinerario que en su recorrido irá dando cuenta de un posicionamiento ideológico frente a los fenómenos derivados de la industria cultural –fenómenos camp y kitsch–, los géneros menores, la intertextualidad y lo intermedial. En esta curva, El jinete polaco significaría un punto de inflexión dentro de la producción narrativa del autor. En ella Muñoz Molina escribe una novela inspirada todavía en un motivo pictórico, pero abandona la astucia narrativa del final sorprendente y combina múltiples peripecias, historias cruzadas, diversos puntos de vista que apuntan a construir algo semejante a lo que Mario Vargas Llosa intuyó en Cien años de soledad de García Márquez, una “novela total”.

    Building on insights gained from the discovery of the antimalarial ozonide arterolane (OZ277), we now describe the structure-activity relationship (SAR) of the antimalarial ozonide artefenomel (OZ439). Primary and secondary amino ozonides had higher metabolic stabilities than tertiary amino ozonides, consistent with their higher pK a and lower log D 7.4 values. For primary amino ozonides, addition of polar functional groups decreased in vivo antimalarial efficacy. For secondary amino ozonides, additional functional groups had variable effects on metabolic stability and efficacy, but the most effective members of this series also had the highest log D 7.4 values. For tertiary amino ozonides, addition of polar functional groups with H-bond donors increased metabolic stability but decreased in vivo antimalarial efficacy. Primary and tertiary amino ozonides with cycloalkyl and heterocycle substructures were superior to their acyclic counterparts. The high curative efficacy of these ozonides was most often associated with high and prolonged plasma exposure, but exposure on its own did not explain the presence or absence of either curative efficacy or in vivo toxicity.

    One of related materials to high-temperature superconductors (HTSC's) with nominal compositions of (Pb0.5Co0.5)Sr2(Y1xCax)Cu2Oz (x=0∼0.6) is synthesized and characterized. All samples are nearly single-phase, and its crystal structure is likely to be so-called "1-2-1-2" type which is one of typical structures of HTSC's. Electrical resistivity is decreased as x increases. While superconductivity is not observed at temperatures between room-temperature and 20 K for all samples, temperature dependence of the resistivity exhibits metallic behavior down to 150 K for x=0.5. Phase formation and transport behavior are discussed focusing on mixed valence-state of Co2+ and Co3+.

    Full Text Available Epistemological considerations of philosophers and scientists from the late nineteenth century to the mid-twentieth century guided Brazilian physiologist Miguel Ozório de Almeida (1890-1953 in formulating his researches and participating in national and international scientific debates. With his siblings, Álvaro Ozório de Almeida and Branca de Almeida Fialho, he participated in debates on Brazilian educational and scientific system’s reform and in international organizations. The family’s residence in Rio de Janeiro housed a laboratory that became a reference in experimental physiology researches in Brazil. This article aims to present Miguel Ozório de Almeida’s conception of science, constructed mainly within the private laboratory’s sociability, providing new aspects of scientific work production in Brazil in the early twentieth century. I argue that Ozório de Almeida’s stand as an internationalist physiologist in national and international contexts was related to his reading of texts by Ernest Mach, Pierre Duhem, Henri Poincaré and William James.

  7. BeerOz, a set of Matlab routines for the quantitative interpretation of spectrophotometric measurements of metal speciation in solution

    Brugger, Joël

    2007-02-01

    The modelling of the speciation and mobility of metals under surface and hydrothermal conditions relies on the availability of accurate thermodynamic properties for all relevant minerals, aqueous species, gases and surface species. Spectroscopic techniques obeying the Beer-Lambert law can be used to obtain thermodynamic properties for reactions among aqueous species (e.g., ligand substitution; protonation). BeerOz is a set of Matlab routines designed to perform both qualitative and quantitative analysis of spectroscopic data following the Beer-Lambert law. BeerOz is modular and can be customised for particular experimental strategies or for simultaneous refinement of several datasets obtained using different techniques. Distribution of species calculations are performed using an implementation of the EQBRM code, which allows for customised activity coefficient calculations. BeerOz also contains routines to study the n-dimensional solution space, in order to provide realistic estimates of errors and test for the existence of multiple local minima and correlation between the different refined variables. The paper reviews the physical principles underlying the qualitative and quantitative analysis of spectroscopic data collected on aqueous speciation, in particular for studying successive ligand replacement reactions, and presents the non-linear least-squares algorithm implemented in BeerOz. The discussion is illustrated using UV-Vis spectra collected on acidic Fe(III) solutions containing varying LiCl concentrations, and showing the change from the hexaaquo Fe(H 2O) 63+ complex to the tetrahedral FeCl 4- complex.

    Full Text Available The dielectric integrity has been one of the major obstacle in bringing out capacitor devices with suitable performance characteristics at high temperatures. In this paper, BxNyOz dielectric films for high temperature capacitors solutions are investigated. The films were grown on silicon substrate by using ion source assisted physical vapor deposition technique. The as-grown films were characterized by SEM, XRD, and XPS. The capacitor structures were fabricated using BxNyOz as a dielectric and titanium as metal electrodes. The elaborated devices were subjected to electrical and thermal characterization. They exhibited low electrical loss and very good stability when subjected to high temperature for a prolonged period of time.

  11. Thermodynamics of protein folding using a modified Wako-Saitô-Muñoz-Eaton model.

    Tsai, Min-Yeh; Yuan, Jian-Min; Teranishi, Yoshiaki; Lin, Sheng Hsien

    2012-09-01

    Herein, we propose a modified version of the Wako-Saitô-Muñoz-Eaton (WSME) model. The proposed model introduces an empirical temperature parameter for the hypothetical structural units (i.e., foldons) in proteins to include site-dependent thermodynamic behavior. The thermodynamics for both our proposed model and the original WSME model were investigated. For a system with beta-hairpin topology, a mathematical treatment (contact-pair treatment) to facilitate the calculation of its partition function was developed. The results show that the proposed model provides better insight into the site-dependent thermodynamic behavior of the system, compared with the original WSME model. From this site-dependent point of view, the relationship between probe-dependent experimental results and model's thermodynamic predictions can be explained. The model allows for suggesting a general principle to identify foldon behavior. We also find that the backbone hydrogen bonds may play a role of structural constraints in modulating the cooperative system. Thus, our study may contribute to the understanding of the fundamental principles for the thermodynamics of protein folding.

  12. Syntactically Silent Subjects: Luis Muñoz and the Poetry of Ellipsis

    Directory of Open Access Journals (Sweden)

    Judith Nantell

    2012-06-01

    Full Text Available Luis Muñoz (1966 is one of contemporary Spain’s most salient poets. His work has been described as demonstrating a discourse of ellipsis; yet no study has examined in detail his masterful use of syntactic and figurative omission. In fact, even though Muñoz’s published collections to date span two centuries, no single study has been devoted to his decidedly innovative expressivity. His work has been commented on in various panoramic essays considering contemporary poetry published in Spain at this temporal intersection and a number of his poems have been gathered into noteworthy anthologies of this same era. His poetry has been nominated for prestigious awards in Spain and in 2001 Correspondencias ‘Correspondences’ received the fourth Premio Internacional de Poesía del 27 as well as the Premio de Ojo Crítico de Poesía . The present study examines Muñoz’s most recent Querido silencio (2006 ‘Dear Silence’ where ellipsis figures prominently as the poet maximizes and exploits conceptual and linguistic efficiency. In one exemplary poem, “Dejar la poesía” ‘Leave Poetry,’ two syntactically silent subjects engage in an innovative conversation concerning the nature of poetry. At the same time this intriguing dialogue also offers a unique response to the essential question framing this poem and the collection as a whole: Why is poetry an addiction?

    Directory of Open Access Journals (Sweden)

    Felipe Oliver Fuentes Kraffczyk

    2012-12-01

    Full Text Available The novel El jinete polaco by Antonio Muñoz Molina is a highly complex work in which the narrator mixes multiple plotlines in an effort to recreate or remember part of his family past. In the process, the collective memory of the town and people of Mágina (an allegoric space that represents the peasant life of the olive growers of southern Spain appears as a rich and contradictory montage of dreams and failures. And in a third level of discourse, the recent past of Spain also emerges through the main historic al events: the civil war, the protracted military government, and the economic development and current consolidation of democracy. In order to achieve this complex and ambitious narrative project, in El jinete polaco time is not represented as uninterrupted historical timeline but as the rich mixture of the simultaneous experiences of different life courses in terms of both values and cultural patterns in order to understand how the rapid social change affects relations between the various age groups. In other words, time is constructed as a synthesis of the biographical dimension within collective memory and major historical events. This paper seeks to point out the similarities and differences between biographical discourse, collective memory and history.

Oito plantas de cada cultivar foram submetidas separadamente a ar filtrado e a ar filtrado + O3, cinco horas por dia, durante quatro dias. Foram avaliadas fotossíntese (Asat, injúrias foliares visíveis e concentração de antocianinas e taninos. Plantas das duas cultivares também foram expostas, durante três meses, a condições ambientais em local contaminado por O3, tendo-se avaliado fotossíntese, injúrias foliares e crescimento. Plantas fumigadas com O3 apresentaram redução de Asat e da atividade fotoquímica, além de manifestação de injúrias foliares. 'Paluma' apresentou maior redução de Asat, injúrias foliares mais severas e redução de taninos. Quando exposta ao ambiente contaminado, 'Paluma' apresentou trocas gasosas mais altas, mas apresentou redução de Asat 30 dias antes que 'Pedro Sato'. O crescimento não foi afetado em 'Pedro Sato', cujas injúrias foliares tiveram menor incidência, severidade e precocidade do que em 'Paluma'. A menor taxa de crescimento de 'Paluma' indica maior sensibilidade ao O3. Apesar de responder com menor intensidade ao estresse induzido pelo O3, a cultivar Pedro Sato não pode ser considerada tolerante, pois apresenta danos fotoquímicos, injúrias foliares e alterações nos conteúdos de metabólitos secundários quando exposta a esse poluente.

    En la hermosa tierra de Pubén, madre y nodriza de uno de los más encumbrados pueblos de Colombia; en Popayán, ciudad procera de la patria, vino a la vida el doctor Juan Jacobo Muñoz Delgado, el 9 de mayo de 1923.

    Aprendió sus primeras letras en la villa natal y luego viajó a la capital, donde se hizo Médico en la Facultad correspondiente de la Universidad Nacional de Bogotá. En 1947 recibió su grado, con honores, con un trabajo de tesis titulado, “Psicodiagnóstico de Rorschach. Aplicaciones Clínicas”.

    Entre 1947 y 1952 se especializó en cirugía oncológica en Nueva York y en Inglaterra y, a su regreso al país, en 1952, ingresó al Instituto Nacional de Cancerología, aún bajo la sabia Dirección del doctor César Augusto Pantoja, en el cual entró a formar parte del Departamento de Cirugía. En los años 1958 y 1959 ocupó la Jefatura del Departamento de Cirugía General del Hospital de La Samaritana y desde 1960, y por largo ‘tiempo, fue Jefe de Cirugía del Instituto Nacional de Cancerología. Ocupa también puestos directivos en diferentes instituciones asistenciales.

    Con una inclinación nata a la docencia, fue profesor de su especialidad en la Facultad de Medicina de la Universidad Nacional y en la de la Universidad Javeriana. Más tarde, entre 1965 y 1966, Ministro de Salud Pública y, posteriormente, entre 1971 y 1974, ocupó la cartera de Educación Nacional.

    Ingresó luego al campo diplomático y, en los años 1974 a 1977, fue Embajador de Colombia ante la UNESCO. Ya en Bogotá, se encargó de la Rectoría de la Universidad de los Andes entre 1978 y 1979, año en el cual, y en cumplimiento del Parágrafo 3 del Artículo 3 de la Ley 02 del 19 de enero de 1979, la Academia Nacional de Medicina 10 recibió como miembro Honorario, en su condición de ex Ministro de Salud.

    Stern, Jeffrey

    2003-01-01

    Works of applied psychoanalysis normally use psychoanalytic theory to reveal the secret meanings of works of art. An attempt is made to reverse the directionality of such analyses and see whether a work of art, The Wizard of Oz, has something to teach psychoanalysis about adolescent female psychosexual development. The author argues that the popularity and importance of the film is an effect of its symbolic representation of a girl's entry into menarche, and the meaning of this milestone for herself and for her mother. He addresses ideas about feminine castration fears (or what more recently have been called fears of genital injury), issues about menopause, and fantasies--both surprising and violent--around the meanings of menarche for both mother and daughter.

    Full Text Available Los cruces y correspondencias del tiempo histórico y el tiempo biográfico es el sello característico de la ambiciosa novela de Antonio Muñoz Molina, El jinete polaco. Por intermediación del recuerdo el narrador fusiona su memoria individual en la memoria colectiva de Mágina, mítica población que sintetiza y condensa la crisis de una España atrapada en la encrucijada entre la tradición y la modernidad. De esta manera, el tiempo no avanza como un relato histórico convencional, como un conjunto de información lo suficientemente documentada y desplegada en una secuencia lineal, sino como un testimonio caótico que remueve nuevos lugares escondidos con celo dentro del yo. Dicho con otras palabras, a través de la subjetividad de un individuo que analiza en retrospectiva su experiencia personal, irrumpe en paralelo un mosaico fragmentario del pasado y presente de España. Este trabajo tiene por objeto revisar cómo por intermediación del lenguaje la novela logra entretejer una gran variedad de «emplazamientos»; entendiendo por emplazamiento la síntesis de «plaza» (lugar, y plazo (tiempo, y cómo estos binomios espacio-temporales re-construyen la personalidad de un yo.

    The purpose of this study is to investigate whether the international standard electrode placement (C4-A1) can be replaced by an alternative placement (Fpz-Cz/Pz-Oz) in an automatic sleep monitoring system without losing Rechtschaffen and Kales (R-K) balances. Single night-sleep polygraphic recordings of 10 patients, screened in a clinical sleep disorder setting, were recorded simultaneously with both placements, and visual sleep classification was performed separately by two independent observers. Interobserver and interplacement agreement were evaluated by way of average (dis)agreement matrices and kappa values computed for overall and individual stage scoring. Interobserver agreement for both the test and the standard electrode placements and interplacement agreement for both observers were assessed as fair to good or excellent. Scoring differences were evaluated by the rank sign test applied to clinical and theoretical difference scores. It appears that the interplacement differences are about equal to the interobserver differences, except for a slight tendency for sleep to be scored in a deeper stage with the proposed alternative placement. The data are presented and discussed in relation to current literature concepts.

    Full Text Available Head-mounted displays and other wearable devices open up for innovative types of interaction for wearable augmented reality (AR. However, to design and evaluate these new types of AR user interfaces, it is essential to quickly simulate undeveloped components of the system and collect feedback from potential users early in the design process. One way of doing this is the wizard of Oz (WOZ method. The basic idea behind WOZ is to create the illusion of a working system by having a human operator, performing some or all of the system’s functions. WozARd is a WOZ method developed for wearable AR interaction. The presented pilot study was an initial investigation of the capability of the WozARd method to simulate an AR city tour. Qualitative and quantitative data were collected from 21 participants performing a simulated AR city tour. The data analysis focused on seven categories that can have an impact on how the WozARd method is perceived by participants: precision, relevance, responsiveness, technical stability, visual fidelity, general user-experience, and human-operator performance. Overall, the results indicate that the participants perceived the simulated AR city tour as a relatively realistic experience despite a certain degree of technical instability and human-operator mistakes.

    The CaO-½Gd2O3-CoOz system prepared at 885 °C in air consists of two thermoelectric calcium cobaltate compounds, namely, the 2D thermoelectric oxide solid solution, (Ca3-xGdx)Co4O9-z (0 ≤ x ≤ 0.42) which has a misfit layered structure, and the 1D Ca3Co2O6 compound which consists of chains of alternating CoO6 trigonal prisms and CoO6 octahedra. Ca3Co2O6 was found to be a point compound. In the peripheral binary systems, Gd was not present in the Ca site of CaO, while a small solid solution region was identified for (Gd1-xCax)O(3-z)/2 (0 ≤ x ≤ 0.075). A solid solution region of distorted perovskite, (Gd1-xCax)CoO3-z (0 ≤ x ≤ 0.24, space group Pnma) was established. The structure of a member of the solid solution, (Gd0.92Ca0.08)CoO3-z, was determined using high resolution synchrotron radiation. A ternary oxide compound CaGdCoO4-z which has an orthorhombic structure (Bmab) was found to be stable at this temperature. Five solid solution tie-line regions and six three-phase regions were determined in the CaO-½Gd2O3-CoOz system. A comparison of the phase diagrams of the CaO-½R2O3-CoOz (R = La, Sm and Gd) systems is provided.

    Full Text Available Ozone is a colorless and unstable gas with pungent smell and partially soluble in water, which is characterized by its high oxidant power. It is a strong agent disinfectant with high power germicidal properties acting in the inactivation of a wide variety of pathogenic organisms, including bacteria, virus and protozoa, presenting a germicidal efficiency that exceeds chlorine. Ozonization has become well-known in recent decades due to implementation of standards increasingly restrictive concerning the by-products of chlorination. Unlike chlorine, ozone do not form halogenated compounds with organic matter. However, it may form several other organic and inorganic. In the food industry, ozone can be use in sanitization processes of equipments and surfaces, as well as in the direct use on foodstuff in order to inactivate microorganisms and to extend shelf-life of food products.O ozônio é um gás incolor de odor pungente, instável e parcialmente solúvel em água, que se destaca por seu elevado poder oxidante. É um forte agente desinfetante com ação sobre uma grande variedade de organismos patogênicos, incluindo bactérias, vírus e protozoários, apresentado uma eficiência germicida que excede ao cloro. O uso do ozônio tornou-se notório nas últimas décadas em função da implementação de padrões cada vez mais restritos em relação aos subprodutos da cloração. Ao contrário do cloro, o ozônio não forma subprodutos halogenados com a matéria orgânica, mas pode induzir a formação de outros subprodutos orgânicos e inorgânicos. Na indústria de alimentos, o ozônio pode ser utilizado em processos de sanitização de superfícies e equipamentos, bem como no uso direto sobre as matérias-primas com o objetivo de inativar microrganismos e aumentar a vida-de-prateleira dos produtos alimentícios.

    Full Text Available Antonio Muñoz (1884-1960 is usually remembered for his successful career in the administration and conservation of the monumental heritage in Rome during the Fascist era. His brief yet relevant activity as a Byzantinist is often underestimated in the secondary literature, despite the fact that, before the 1914-18 war, he was unanimously considered as the most promising Italian specialist in Byzantine art. From 1903 onwards, after completing his studies with Adolfo Venturi, Muñoz developed an interest in Byzantine illumination, which became his primary area of expertise. At this early stage, his most important work was without doubt the new edition of the Rossano Gospels (1907, which was internationally praised as a significant step forward in the history of Byzantine illumination. With the support of previously unpublished or little-known documents, this article aims to provide a new critical analysis of Muñoz’s research on Byzantine illumination, as well as a more balanced evaluation of its impact on the scholarly community at the turn of the twentieth century.

    Full Text Available Resumo Raízes de batata-baroa (Arracacia xanthorrhiza Bancroft foram imersas em água borbulhada com ozônio, para avaliar o controle de bactérias do gênero Erwinia. Além de análise visual das raízes, avaliaram-se a atividade das enzimas pectinolíticas pectinametilesterase e poligalacturonase, e as características físico-químicas (perda de massa, variação de cor, teores de açúcares e amido, durante o armazenamento. As raízes foram imersas em água ozonizada (1,52 mg L-1, por períodos de até 30 min. Em seguida, foram acondicionadas em câmara climática e avaliadas durante 10 dias. Não houve diferença visual aparente entre os tratamentos. Entretanto, raízes tratadas com ozônio por 30 min apresentaram menor atividade específica das enzimas pectinametilesterase. Houve efeito linear para açúcares solúveis totais e perda de massa, e efeito quadrático para açúcares redutores e não redutores, significativos apenas para o período de armazenamento. A imersão de raízes de batata-baroa em água borbulhada com ozônio por até 30 min não foi suficiente para o controle de bactérias do gênero Erwinia. Nas condições adotadas no trabalho, a ozonização não provoca alteração na perda de massa, no teor de amido, açúcares solúveis totais, açúcares redutores e açúcares não redutores, e na variação de cor das raízes de batata-baroa.

Una buena comprensión de los requisitos puede conducir a mejores productos de software que satisfagan las necesidades de los interesados. Sin embargo, el proceso de captura de requisitos se torna difícil para el analista debido, en gran parte, al carácter presencial que tienen las reuniones que se realizan con tal fin y a la dificultad que presentan algunas personas para expresar sus ideas de forma clara. En este artículo se presenta UNC-Analista, una propuesta de experimento Mago de Oz enfocado al diseño de un sistema de diálogo controlado que posibilite la labor del analista durante el proceso de obtención de requisitos. Con este sistema será posible capturar un corpus de requisitos, que servirá como base para la construcción futura de un sistema automático para la obtención de requisitos.Requirements elicitation is one of the most important phases in software development process. A good requirements understanding can lead to better software products, achieving satisfaction of stakeholder needs. However, requirements-capture process is sometimes difficult for analysts, because of the face-to-face character of the meetings required for it and because of difficulties of people for expressing clearly their ideas. In this paper we present UNC-Analista, a proposal for Wizard-of-Oz experiment focused on the design of a dialogue-controlled system for helping the analyst labor in the requirements elicitation process. With this system will be possible to capture a requirements corpus, for leading a future development of an automatic requirements elicitation system.

    Full Text Available This study was conducted to evaluate the decomposition kinetics of gaseous ozone in peanut grains. This evaluation was made with 1-kg peanut samples, moisture contents being 7.1 and 10.5% wet basis (w.b., placed in 3-liter glass containers. The peanut grains were ozonated at the concentration of 450 µg L-1, at 25 and 35 ºC, with gas flow rates of 1.0 and 3.0 L min-1. Time of saturation was determined by quantifying the residual concentration of ozone after the gas passed through the grains to constant mass. The decomposition kinetics of ozone was evaluated after the grain mass was ozone-saturated. For the peanut grains whose moisture content was 7.1% (w.b., at 25 and 35ºC and with flow rates of 1.0 and 3.0 L min-1, the values obtained for time of saturation of gaseous ozone ranged between 173 and 192 min; the concentration of saturation was approximately 260 µg L-1. For the grains whose moisture content was 10.5% (w.b., a higher residual concentration of gaseous ozone was obtained at 25 ºC, that of 190 µg L-1. As regards the half-life of ozone, the highest value obtained was equivalent to 7.7 min for grains ozonated at 25 ºC, while for those with moisture content of 10.5% at 35 ºC, half-life was 3.2 min. In the process of ozone decomposition in peanut grains, temperature was concluded to be the key factor. An increase of 10 ºC in the temperature of the grains results in a decrease of at least 43% in the half-life of ozone.Este trabalho foi desenvolvido com o objetivo de avaliar a cinética de decomposição do ozônio em grãos de amendoim.

    2013-12-01

    Full Text Available Two recently published books, one from Spain (Muñoz Machado, 2012 and the other from Colombia (Mendoza Martelo, 2013, evince concerns with respect to the territorial organization in both countries. What is the appeal of the territorial model? With common constitutional errors occurring in the territorial area, and a crisis in both function and coordination in various levels of the Government –as well as in the different regions and autonomous communities–, is legal reform preferable to constitutional change? These are some of the issues raised and evaluated in current debates. In the work in question, the main problems in Spain are analyzed and the author proposes ways of solving or diminishing these problems, such as a return to centralism, the partial conservation of autonomous communities, the replacement of the current model with a federal State, as well as the possibilities of self-determination and separatism. The proposed study will serve to revise certain aspects of Colombia’s territorial system, in order to determine whether or not reformation is necessary.

    In this study we report on a ZnxZryOz mixed oxide type catalyst capable of converting a syngas-derived C2+ mixed oxygenate feedstock to isobutene-rich olefins. Aqueous model feed comprising of ethanol, acetaldehyde, acetic acid, ethyl acetate, methanol, and propanol was used as representative liquid product derived from a Rh-based mixed oxygenate synthesis catalyst. Greater than 50% carbon yield to C3-C5 mixed olefins was demonstrated when operating at 400-450oC and 1 atm. In order to rationalize formation of the products observed feed components were individually evaluated. Major constituents of the feed mixture (ethanol, acetaldehyde, acetic acid, and ethyl acetate) were found to produce isobutene-rich olefins. C-C coupling was also demonstrated for propanol feedstock - a minor constituent of the mixed oxygenate feed - producing branched C6 olefins, revealing scalability to alcohols higher than ethanol following an analogous reaction pathway. Using ethanol and propanol feed mixtures, cross-coupling reactions produced mixtures of C4, C5, and C6 branched olefins. The presence of H2 in the feed was found to facilitate hydrogenation of the ketone intermediates, thus producing straight chain olefins as byproducts. While activity loss from coking is observed complete catalyst regeneration is achieved by employing mild oxidation. For conversion of the mixed oxygenate feed a Zr/Zn ratio of 2.5 and a reaction temperature of 450oC provides the best balance of stability, activity, and selectivity. X-ray diffraction and scanning transmission electron microscopy analysis reveals the presence of primarily cubic phase ZrO2 and a minor amount of the monoclinic phase, with ZnO being highly dispersed in the lattice. The presence of ZnO appears to stabilize the cubic phase resulting in less monoclinic phase as the ZnO concentration increases. Infrared spectroscopy shows the mixed oxide acid sites are characterized as primarily Lewis type acidity. The direct relationship between

    Three kinds of hybrids, Ag2CO3/TiO2, Ag2C2O4/TiO2 and Ag3PO4/TiO2 comprising of P25-TiO2 and silver-containing photocatalyst, (together coded as AgxMyOz/TiO2 (M = C, P)) were prepared via a facile precipitation method. The photocatalytic activity and stability of the as-prepared AgxMyOz/TiO2 was compared by monitoring the oxidation of propylene under visible light irradiation. Results showed that both Ag2CO3/TiO2 and Ag2C2O4/TiO2 exhibit perfect performance with a high propylene degradation removal rate of 88% and 78%, respectively, during four successive experimental runs. On the contrary, for Ag3PO4/TiO2, the photocatalytic activity gradually declines to 8% from 32% under the same conditions. In order to explore the reason for the above remarkable difference in activity and stability over AgxMyOz/TiO2, X-ray photoelectron spectroscopy (XPS), X-ray diffraction (XRD) and UV-vis diffuse reflectance spectroscopy (DRS) were used to investigate the change of AgxMyOz/TiO2 before and after irradiation. It was found that three silver-containings, Ag2CO3, Ag2C2O4 and Ag3PO4 on the surface of TiO2, all experienced photo-corrosion to various extents during irradiation process. Surprisingly, the effect of photo-corrosion on visible light activity and stability among various AgxMyOz/TiO2 is very different. For both Ag2CO3 and Ag2C2O4, they are easily decomposed into metallic Ag and CO2, and gaseous CO2 escaped from catalyst leaving silver nanoparticles on the surface of TiO2 resulted in the formation of plasmonic photocatalyst Ag/TiO2. The synergetic effect between surface plasma resonance of silver and interfacial electron transfer over the obtained Ag/TiO2 heterojunctions is in favor of the superior photocatalytic performance under visible light. While for Ag3PO4/TiO2, Ag3PO4 on the surface of TiO2 is partially photo-decomposed into Ag and phosphorus oxide and the phosphorus oxide covering on the surface of undecomposed Ag3PO4/TiO2 deactivates its photocatalytic performance

    Artefenomel (OZ439) is a novel synthetic trioxolane with improved pharmacokinetic properties compared with other antimalarial drugs with the artemisinin pharmacophore. Artefenomel has been generally well tolerated in volunteers at doses up to 1600 mg and is being developed as a partner drug in an antimalarial combination treatment. We investigated the efficacy, tolerability, and pharmacokinetics of artefenomel at different doses in patients with Plasmodium falciparum or Plasmodium vivax malaria. This phase 2a exploratory, open-label trial was done at the Hospital for Tropical Diseases, Bangkok, and the Shoklo Malaria Research Unit in Thailand. Adult patients with acute, uncomplicated P falciparum or P vivax malaria received artefenomel in a single oral dose (200 mg, 400 mg, 800 mg, or 1200 mg). The first cohort received 800 mg. Testing of a new dose of artefenomel in a patient cohort was decided on after safety and efficacy assessment of the preceding cohort. The primary endpoint was the natural log parasite reduction per 24 h. Definitive oral treatment was given at 36 h. This trial is registered with ClinicalTrials.gov, number NCT01213966. Between Oct 24, 2010, and May 25, 2012, 82 patients were enrolled (20 in each of the 200 mg, 400 mg, and 800 mg cohorts, and 21 in the 1200 mg cohort). One patient withdrew consent (before the administration of artefenomel) but there were no further dropouts. The parasite reduction rates per 24 h ranged from 0·90 to 1·88 for P falciparum, and 2·09 to 2·53 for P vivax. All doses were equally effective in both P falciparum and P vivax malaria, with median parasite clearance half-lives of 4·1 h (range 1·3-6·7) to 5·6 h (2·0-8·5) for P falciparum and 2·3 h (1·2-3·9) to 3·2 h (0·9-15·0) for P vivax. Maximum plasma concentrations, dose-proportional to 800 mg, occurred at 4 h (median). The estimated elimination half-life was 46-62 h. No serious drug-related adverse effects were reported; other adverse effects were

    Full Text Available Há um crescente interesse em tecnologias que melhorem a qualidade dos alimentos, bem como o aspecto segurança alimentar. Após a água, o café é a bebida mais consumida no planeta, existindo uma demanda crescente por tipos especiais em alguns países importadores, como o café despolpado. Este tipo é obtido pela remoção da mucilagem, ao se submeter o café à fermentação, cujo processo varia com o clima e a microbiota associada, entre outros fatores, podendo levar ao detrimento da qualidade do produto e da saúde do consumidor. Assim, faz-se necessário investigar novas tecnologias que possam auxiliar na obtenção de produtos com melhor padronização, qualidade e que ofereçam maior segurança alimentar. O ozônio e o ultra-som são tecnologias usadas em diversas áreas, com grande flexibilidade e resultados promissores na obtenção e no tratamento de uma infinidade de alimentos. São conhecidas as potentes características oxidantes e microbicidas de ambos, mas seus mecanismos ainda não são bem esclarecidos quando utilizados em tecidos vivos. Seus efeitos sobre os vários parâmetros de qualidade devem ser estudados, compreendidos e ajustados, antes de serem utilizados em larga escala na indústria. No presente trabalho, foi aplicado o ozônio ou o ultra-som como tratamentos prévios à fermentação do café, demonstrando sua eficácia na melhoria da segurança alimentar do café despolpado, sem alteração perceptível da qualidade da bebida.There is a growing interest in technologies that improve food quality, as well as food safety aspects. After water, coffee is the most consumed beverage in the planet, with a rising demand for special types, such as fermented coffee, in some importing countries. This type of coffee is obtained by removing the mucilage, submitting the coffee to fermentation, a process that varies with the climate and the associated natural micro-organisms, among other factors, and that can lead to detrimental

    Full Text Available I would like to add my voice to the words of congratulations and thanks to the British Library for organising this forum, and for their generosity in making it possible for me to come across the world to be part of it. The issues we are discussing today have an importance extending beyond cellulose acetate, as they reflect our ability as custodians to deal with common threats to the documentary heritage we are charged with preserving. As I will argue later, we need to see this situation in the context of the full range of preservation management issues that face our institutions. While it imposes a burden and a challenge on us as preservation managers, it also presents opportunities to sort out some things that have needed attention for some time. I have been asked to talk about problems with cellulose acetate microfilm collections in Australia, and specifically the strategies – both national and local – that have been adopted or at least explored in response to those problems. In the time I have I will not be going into any of these in great detail, but I hope I can give you some sense of the situation down under, and perhaps draw out a few issues that might make this more than just an ‘us too’ session! One thing to emphasise from the start is that we have had a number of goes at dealing with acetate microfilm collections: it is not a newly discovered problem in Australia. One significant context in which we have been working is that of a national strategy for all kinds of cellulose acetate collection materials. Explaining this national strategy will form a major part of my presentation, with issues and approaches specific to microfilm discussed towards the end.

    Full Text Available Psidium guajava 'Paluma' has being tested as an ozone (O3 bioindicator and responds with pigmentation between the veins on the adaxial surface, due to the accumulation of phenolic compounds. These compounds act as non-enzymatic antioxidants that neutralize reactive oxygen species (ROS, formed from O3. This study aimed to evaluate the leaf structure of plants with and without visible symptoms and to establish these symptoms at the cellular level. Beside this we also aimed to detect structural changes that can minimize the effects of the O3 on the plant. The accumulation of phenolic substances, stomatal density and structural changes in P. guajava 'Paluma' leaf tissues exposed during the four seasons of the year were evaluated. The study was conducted at the Parque Estadual das Fontes do Ipiranga ( PEFI, which is a park in the city of São Paulo that has high levels of O3. Leaves with symptoms showed, on the adaxial surface, anthocyanin accumulation in the vacuoles of epidermal cells and hypodermis. When the symptoms were more intense this accumulation was observed even in the first three layers of palisade parenchyma. Comparing symptomatic and asymptomatic leaves, there was higher accumulation of phenolic compounds in the symptomatic leaves. Some parenchyma cells adjacent to substomatal chambers showed intrusive growth towards the stomatal pore, promoting its occlusion, which could reduce the entry of O3 in the leaf. The accumulation of anthocyanins and other phenolic compounds, in addition to the occlusion of the chamber, protect the plant against O3 effects. These features and the compact arrangement of the mesophyll contribute to why Psidium guajava 'Paluma' does not present cell death, a symptom usually observed in species sensitive to O3.Psidium guajava 'Paluma' vem sendo testada como bioindicadora de ozônio (O3 e responde com pigmentações, entre as nervuras, na superfície adaxial, decorrente do acúmulo de compostos fenólicos.

A presente pesquisa avaliou a remoção de substâncias húmicas na FiME com pré-oxidação, com ozônio e peróxido de hidrogênio, utilizando para essa avaliação parâmetros indiretos como cor verdadeira, absorvância UV (254 nm e COD. Foram realizados cinco ensaios, utilizando quatro filtros lentos, sendo dois com camada de carvão ativado granular (CAG. Foram ensaiadas várias alternativas de pré-oxidação com ozônio e peróxido de hidrogênio. Foram obtidos bons resultados, tendo como principal conclusão que os filtros lentos com CAG, precedidos de oxidação com ozônio e depois peróxido de hidrogênio, apresentaram remoção média de cor verdadeira de 64%, mas que o peróxido de hidrogênio afeta o desenvolvimento da camada biológica, interferindo no desenvolvimento da perda de carga, na remoção de turbidez, na remoção de coliformes e na remoção de substâncias húmicas.The multistage filtration (FiME is an alternative to accomplish water treatment for small communities, however, as for removal of true color associated to dissolved organic carbon (DOC or humic substances, it have been questioned or reported as low efficiency.

    Full Text Available RESUMO Este trabalho objetivou verificar as inter-relações entre as concentrações de ozônio (O3 e de dióxido de nitrogênio (NO2 na região da Grande Vitória (RGV, Espírito Santo, Brasil. Adotou-se a metodologia vetorial autorregressiva (VAR e o teste de causalidade de Granger. O modelo VAR captura as interdependências lineares entre várias séries temporais, sendo que cada variável possui uma equação estimada que representa sua evolução em termos de suas próprias defasagens e das defasagens das outras variáveis. Já o teste de causalidade de Granger baseia-se em um sistema de equações bivariado para verificar se uma variável é capaz de prever a outra. Os resultados revelaram que as concentrações de O3 e de NO2 da Região (estação de Laranjeiras foram as menos afetadas por concentrações de outras estações. Devido à localização, as concentrações de O3 e NO2 da Enseadá do Suá tiveram significativa influência de outras regiões, especialmente de Jardim Camburi, Ibes e Vitória - Centro. A concentração de ozônio na região do Ibes foi fortemente influenciada pelas concentrações de O3 e de NO2 da Enseada do Suá. Além disso, as concentrações de Cariacica sofreram impactos relevantes das concentrações da Enseada do Suá, provavelmente, devido à direção do vento Norte/Nordeste, predominante na RGV.

    Full Text Available Na Região Metropolitana de São Paulo, a rede de monitoramento da qualidade do ar registra frequentemente valores de concentração de ozônio superiores aos estabelecidos pela legislação em vigor no Brasil. Em algumas ocasiões, condições meteorológicas favoráveis ao processo de formação de ozônio possibilitam a ocorrência de altas concentrações de ozônio durante diversos dias consecutivos na região. A influência de condições meteorológicas no episódio de poluição, registrado entre os dias de 24 de fevereiro e 05 de março de 2003, foi avaliada através de simulações numéricas com o modelo SPM-BRAMS. Estudos observacionais mostram que a ocorrência de ventos fracos, principalmente, durante o período noturno e durante as manhãs, favorece a formação de altas concentrações de ozônio sobre a região. O horário de entrada e a atuação da brisa marítima são fundamentais para o transporte do ozônio e de seus precursores. Essas condições foram bem simuladas pelo modelo. Para os dias mais críticos, quando diversas estações de monitoramento registraram a ocorrência de violações ao padrão nacional de qualidade do ar, o modelo simulou adequadamente as condições atmosféricas determinantes para a manutenção de valores elevados nas concentrações de ozônio, sem a necessidade de nenhum procedimento artificial ao longo das integrações.In the Metropolitan Area of Sao Paulo, air quality monitoring network often register ozone concentration values higher than those established by Brazilian legislation. In some occasions, weather conditions favorable to ozone formation allow the occurrence of high concentration values for several consecutive days in the area.

    Full Text Available Abstract In the light of the power concepts theorized by Michel Foucault, this article investigates Erdal Oz's novel Yaralisin (You’re Wounded. Foucault’s power structure that systematized in Subject and Power (1961, History of Sexuality (1984, Birth of Prison (1975, The Birth of Biopolitics (2004, has similarities with crime production that the novel reflects. Accordingly, individuals are being standardized in the prison through programs, strategies and technics that the power structure determined. In this process, there is no direct enforcement on the individual. The power structure connects the individual to itself through knowledge and body. In Oz’s novel the subject depending on space changing are being standardized and transformed into the “Nuri” character, as we read in the text. At the base of becoming standard individual through lost of identity, there is crime production. As for crime production, it takes shape in accordance with space. In the novel, space dependent suffering, inflicted on individuals, places the subject on a hierarchical plane, as Foucault has also indicated, and brings an end to existence. The power structure, cutting off the individual from his private space, taking him first into the interrogation room, and then to the prison, has made him a part of the system and has objectified him. The digestive effect of the power structure has become even more concrete with the presence of the second person narrator within the narrative plane; depersonalization has taken place within the new order.

    Magnetization studies were carried out on Y 1 Ba 2 Cu 3 O z (YBCO) thin films that were e-beam evaporated onto circular discs of single-crystal SrTiO 3 with (001) and (110) faces as well as KTaO 3 with (001) faces. The measurements were made using vibrating sample (VSM) and SQUID-based magnetometry with the applied field perpendicular to the substrate surface. Critical current densities J c (H,T) are deduced from the magnetic hysteresis. Flux creep effects are observed over longer periods with the SQUID magnetometer. Analysis of the results of low frequency response of these films to collinear ac and dc magnetic fields are compared with the dc magnetometry results. J c (H,T) is observed to be quite sensitive to the type of epitaxial growth on the various substrates. 16 refs., 10 figs

    2011-01-01

    This research presents a structural and photocarrier radiometric (PCR) characterization of Cu x (CdTe) y O z thin films grown using reactive radiofrequency co-sputtering. Electronic distribution induced by variations in dopant concentration as a function of the position was studied using photocarrier radiometric images. Optical and structural characterization of these thin films was carried out by using micro Raman spectroscopy and X-ray diffraction. Due to its nondestructive and noncontact characteristics, the PCR is an excellent technique that permits one to obtain details of lateral electronic distribution across the sample. It was found that Cu target power influences the electronic distribution and produces different phases such as Cu 2 Te and CdO.

    Workplaces today demand graduates who are prepared with field-specific knowledge, advanced social skills, problem-solving skills, and integration capabilities. Meeting these goals with didactic learning (DL) is becoming increasingly difficult. Enhanced training methods that would better prepare tomorrow's graduates must be more engaging and game-like, such as feedback based e-learning or simulation-based training, while saving time. Empirical evidence regarding the effectiveness of advanced learning methods is lacking. Objective quantitative research comparing advanced training methods with DL is sparse. This quantitative study assessed the effectiveness of a computerized interactive simulator coupled with an instructor who monitored students' progress and provided Web-based immediate feedback. A low-cost, globally accessible, telemedicine simulator, developed at the Technion-Israel Institute of Technology, Haifa, Israel-was used. A previous study in the field of interventional cardiology, evaluating the efficacy of the simulator to enhanced learning via knowledge exams, presented promising results of average scores varying from 94% after training and 54% before training (n=20) with Padvantage (P=.01) was found in favor of the WOZ training approach. Content type and training audience were not significant. This study evaluated the contribution of an integrated teaching environment using a computerized interactive simulator, with an instructor providing immediate Web-based immediate feedback to trainees. Involvement of an instructor in the simulation-based training process provided better learning outcomes that varied training content and trainee populations did not affect the overall learning gains. ©Aric Katz, Ronnie Tepper, Avraham Shtub.

    Reptile species, and in particular snakes, are protected by national and international agreements yet are commonly handled illegally. To aid in the enforcement of such legislation, we report on the development of three 11-plex assays from the genome of the carpet python to type 24 loci of tetra-nucleotide and penta-nucleotide repeat motifs (pure, compound and complex included). The loci range in size between 70 and 550 bp. Seventeen of the loci are newly characterised with the inclusion of seven previously developed loci to facilitate cross-comparison with previous carpet python genotyping studies. Assays were optimised in accordance with human forensic profiling kits using one nanogram template DNA. Three loci are included in all three of the multiplex reactions as quality assurance markers, to ensure sample identity and genotyping accuracy is maintained across the three profiling assays. Allelic ladders have been developed for the three assays to ensure consistent and precise allele designation. A DNA reference database of allele frequencies is presented based on 249 samples collected from throughout the species native range. A small number of validation tests are conducted to demonstrate the utility of these multiplex assays. We suggest further appropriate validation tests that should be conducted prior to the application of the multiplex assays in criminal investigations involving carpet pythons.

    Bi 2 (Sr,Ln) 2 CuO z (Ln = Nd, Sm) single crystals were successfully grown by a self-flux method from stoichiometric and (Bi, Cu)-rich melts. Thermal analysis and thermogravimetry were used to determine stability and the melting sequence of Bi 2 (Sr,Ln) 2 CuO z phases in air. As-grown crystals of the ideal Bi 2 (Sr,Ln) 2 CuO z phase, of dimensions 1x0.5x0.03 mm 3 , exhibit superconducting behaviour with critical temperature T c = 21 K for the Bi 1.9 Sr 1.6 Nd 0.6 CuO z crystal and Tc = 14 K for the Bi 1.8 Sr 1.6 Sm 0.6 CuO z crystal. The compositions of these crystals were homogeneous and close to the stoichiometric composition. We report on the growth of Bi 2 Sr 2-x Sm x CuO z single crystals of large dimensions 9x3x0.03 mm 3 using Bi 2 Sr 1.5 Sm 0.5 CuO z as precursor and Bi 2 CuO 4 as flux. (author)

    The purpose of this paper is to study the influence of the choice of internal temperatures on the composition of C x H y O z N t plasmas out of thermodynamic equilibrium. The numerical calculation is specially performed for CH 2 plasma in the pressure range 0.1-1 MPa and for the electron temperature range 5000-30 000 K. Precisely, the investigation of this plasma allows one to show that the choice of internal temperatures can have more influence on plasma composition than the choice of the form of the two-temperature Saha and Guldberg-Waage laws. Indeed, for one of the supposed hypotheses, it is observed that the two forms of the two-temperature system used here can give the same equilibrium composition by uncoupling the excitation temperature of the diatomic and the monatomic species. Great attention must then be given to the adopted hypothesis for internal temperature and not only to the form of the two temperature system used. An accurate comparison between the two models requires the measurement of plasma parameters such as the various internal temperatures and the species concentration. Therefore, we have also carried out an analysis of the potential experimental diagnostics of these plasma parameters. Such diagnostics can help to test and validate theoretical models

    The irreversibility properties of high-T c superconductors are of major importance for technological applications. For example, a high irreversibility magnetic field is a more desirable quality for a superconductor . The irreversibility line in the H-T plane is constituted by experimental points, which divides the irreversible and reversible behavior of the magnetization. The irreversibility lines for series of La 1.5+x Ba 1.5+x-y Ca y Cu 3 O z polycrystalline samples with different doping were investigated. The samples were synthesized using the usual solid estate reaction method. Rietveld-type refinement of x-ray diffraction patterns permitted to determine the crystallization of material in a tetragonal structure. Curves of magnetization ZFC-FC for the system La 1.5+x Ba 1.5+x-y Ca y Cu 3 O z , were measured in magnetic fields of the 10-20,000 Oe, and allowed to obtain the values for the irreversibility and critical temperatures. The data of irreversibility temperature allowed demarcating the irreversibility line, T irr (H). Two main lines are used for the interpretation of the irreversibility line: one of those which suppose that the vortexes are activated thermally and the other proposes that associated to T irr a phase transition occurs. The irreversibility line is described by a power law. The obtained results allow concluding that in the system La 1.5+x Ba 1.5+x-y Ca y Cu 3 O z a characteristic bend of the Almeida-Thouless (AT) tendency is dominant for low fields and a bend Gabay-Toulouse (GT) behavior for high magnetic fields. This feature of the irreversibility line has been reported as a characteristic of granular superconductors and it corroborates the topological effects of vortexes mentioned by several authors .

    We determined the synthesis conditions for successive ionic layer deposition of the Sn 16 (OH) x PW 19 O y ·nH 2 O nanolayers on silica surfaces. The synthesized layers were characterized using UV-Vis and FTIR absorption spectroscopies, X-ray photoelectron spectroscopy (XPS), X-ray diffraction (XRD), scanning electron microscopy (SEM), and atomic force microscopy (AFM). On heating the as-synthesized layers to 200-500 deg. C in air, incorporated water evaporate, while M-OH groups are condensed and concentration of the W-O-W and W-O-Sn bonds increase. The layers have amorphous agglomerate-like structure. The agglomerate size is from 20 to 100 nm. Upon heating to 600 deg. C, the size insignificantly increases, the agglomerate form being practically unchanged. The data obtained allow conclusion that the layers present a hybrid compound consisting of fragments of isopoly-(Sn x O y H z ) and heteropoly-(H x PW y O z ) compounds

    TiSr 2 (RE 1-x Ce x ) 2 Cu 2 O z superconductors (T c ∼20 K) have a 1222-structure with fluorite blocks. Neutron diffraction has been performed on the Eu-containing compound TiSr 2 (Eu 0.8 Ce 0.2 ) 2 Cu 2 O z , with natural Eu, and its crystal structure was refined. The neutron powder diffraction experiment was carried out on the VEGA diffractometer at KENS. The sample was contained in a thin flat cell of 0.5 mm thickness in order to reduce the large absorption effects of natural Eu. The absorption correction for the flat sample was taken into account in the Rietveld refinement. The results show that the O(1) atom in the Ti-layer is shifted from the 4c-site to the split site (8j), and that the concentration is deficient (g∼0.19)

    The degree to which Southern Hemisphere climatic changes during the end of the last glacial period and early Holocene (30-8 ka) were influenced or initiated by events occurring in the high latitudes of the Northern Hemisphere is a complex issue. There is conflicting evidence for the degree of hemispheric teleconnection and an unresolved debate as to the principle forcing mechanism(s). The available hypotheses are difficult to test robustly, however, because the few detailed palaeoclimatic records in the Southern Hemisphere are widely dispersed and lack duplication. Here we present climatic and environmental reconstructions from across Australia, a key region of the Southern Hemisphere because of the range of environments it covers and the potentially important role regional atmospheric and oceanic controls play in global climate change. We identify a general scheme of events for the end of the last glacial period and early Holocene but a detailed reconstruction proved problematic. Significant progress in climate quantification and geochronological control is now urgently required to robustly investigate change through this period. Copyright

    The formation pathway of (Tl 0.5 Pb 0.5 )(Sr 0.9 Ba 0.1 ) 2 Ca 2 Cu 3 O z and (Tl 0.5 Pb 0.5 )(Sr 0.8 Ba 0.2 ) 2 Ca 2 Cu 3 O z was studied by neutron and x-ray diffraction. The following reaction pathway was proposed: thallium oxide and lead oxide react with Sr-rich (Sr 1-x Ca x )CuO 2 and Ca-rich (Ca x Sr 1-x )O to form Sr 4 Tl 2 O 7 and (Ca x Sr 1-x )PbO 3 , respectively. The thallate and the plumbate compounds then form the (Tl 0.5 Pb 0.5 )-1212 phase starting at a temperature of 600 deg. C. Finally, between 850 and 900 deg. C, the 1223 phase is formed from (Tl 0.5 Pb 0.5 )-1212 (Ca x Sr 1-x ) 2 CuO 3 and CuO. Parallel experiments to fabricate the (Tl, Pb)-1223 superconductor resulted in specimens with critical temperatures of 117.5 K and 116 K, respectively, and transition widths of 2 K. Differences between the pathways for the formation of Pb-doped, Sr-rich and Pb-free, Ba-rich Tl-1223 superconductors are discussed

    Full Text Available O presente trabalho tem como objetivo investigar o desempenho da ozonização e da cloração utilizadas na pré-oxidação de água, com elevada concentração de microalgas e cianobactérias, a ser submetida à Filtração Direta Descendente, seguida de desinfecção por cloro, avaliando a qualidade da água produzida, sobretudo no que se refere à remoção de fitoplâncton, à formação de trialometanos e aos testes toxicológicos. Os ensaios, em escala piloto, realizados com a pré-ozonização, apresentaram melhores resultados quando comparados aos realizados com a pré-cloração. Em relação aos trialometanos, por exemplo, a aplicação da pré-ozonização com 2 mgO3/L reduziu em até 50% a formação desses compostos quando comparado ao emprego da pré-cloração. O emprego da ozonização demonstrou ser uma excelente alternativa para o pré-tratamento de água com elevada concentração de microalgas e cianobactérias que utiliza a técnica da filtração direta como processo de potabilização, produzindo água filtrada condizente com o padrão de potabilidade estabelecidos pela Portaria 518/GM do Ministério da Saúde.The present work aims at investigating the performance of ozonation and chlorination used in the pre-oxidation of water with high microalgae and cyanobacteria concentration to be submitted to downflow direct filtration followed by chlorine disinfection, and evaluating the quality of the water produced, especially with regard to phytoplankton removal, trihalomethane formation, and toxicological tests. The pilot scale tests carried outwith the pre-ozonation exhibited better results when compared to the results from the pre-chlorination tests. As to the trihalomethanes, for example, the application of pre-ozonation with 2 mgO3/L reduced in 50% the formation of these compounds whencompared to the application of pre-chlorination. The application of ozonation was shown to be an excellent alternative for pre-treating water with high concentration of microalgae and cyanobacteria when using the direct fi ltration technique for producing water that complies with the drinking water standards established by Portaria GM 518-25/03/2004 of the Brazilian Health Department (Ministério da Saúde.

  17. Distribution of solute atoms in β- and spinel Si6-zAlzOzN8-z by Al K-edge x-ray absorption near-edge structure

    Local environments of solutes in β- and spinel Si 6-z Al z O z N 8-z are investigated by means of Al K x-ray absorption near-edge structure. The experimental spectra are found to be the same throughout the wide solubility range. This suggests that the local environments of Al are independent of the solute concentration. First-principles band-structure calculations are systematically made to interpret the experimental spectra. Effect of a core hole was included into the calculation. Theoretical spectra were obtained using variety of different model structures constructed by a set of plane-wave pseudopotentials calculations in our previous study [K. Tatsumi, I. Tanaka, H. Adachi, and M. Yoshiya, Phys. Rev. B 66, 165210 (2002)]. The numbers of models were 51 and 45 for both β and spinel, respectively. They are classified and averaged according to the local atomic structure of Al solutes. The combination of experimental spectra and theoretical results can unambiguously lead to the conclusion that Al atoms are preferentially coordinated by O atoms in both β and spinel phases. This is consistent with the conclusion obtained by the first-principles total-energy calculations. In the spinel phase, Al atoms are found to be located preferentially at the octahedral cationic site. This agrees with the conclusion in a recent report on the nuclear magnetic resonance experiment

    Full Text Available The purpose of this study was to evaluate the concentrations of tropospheric ozone and VOCs under the sugarcane agro-industry emissions in urban and rural areas of Araraquara, SP. The sampling was performed using active and passive air samplers during the sugarcane harvest and in the period between harvests in 2011 and 2012. Also, canisters were undertaken in 3 situations: during and after the burning of the cane plantations and in an urban area. Instrumental analysis was carried out using gas and ion chromatography. The highest VOC concentrations were found for toluene and d-limonene at the urban area and for ethene during the burning of sugarcane. Although sugarcane industry is an important emission source of ozone precursors, in this study the tropospheric ozone levels do not increased significantly under sugarcane agro-industry emissions.

    In this study, a high-gravity rotating packed bed (HGRPB) was used as a catalytic ozonation reactor to decompose dimethyl phthalate (DMP), an endocrine disrupting chemical commonly encountered. The HGRPB is an effective gas-liquid mixing equipment which can enhance the ozone mass transfer coefficient. Platinum-containing catalyst (Pt/-Al{sub 2}O{sub 3}) of Dash 220N and ultra violet (UV) lamp were combined in the high-gravity ozonation (HG-OZ) system to enhance the self-decomposition of molecular ozone in liquid to form highly reactive radical species. Different combinations of HG-OZ with Dash 220N and UV for the degradation of DMP were tested. These include HG-OZ, HG catalytic OZ (HG-Pt-OZ), HG photolysis OZ (HG-UV-OZ) and HG-UV-Pt-OZ. The result indicated that all the above four ozonation processes result in significant decomposition of DMP and mineralization of total organic carbon (TOC) at the applied ozone dosage per volume of liquid sample of 1.2 g L{sup -1}. The UV and Pt/{gamma}-Al{sub 2}O{sub 3} combined in HG-OZ can enhance the TOC mineralization efficiency ({eta}{sub TOC}) to 56% (via HG-UV-OZ) and 57% (via HG-Pt-OZ), respectively, while only 45% with ozone only. The process of HG-UV-Pt-OZ offers the highest {eta}{sub TOC} of about 68%.

  10. Advanced oxidative process with ozone of effluents contaminated by MN and other heavy metals originated in the acid drainage in uranium mine; Processo oxidativo avançado com ozônio de efluentes contaminados por MN e outros metais pesados originados na drenagem ácida em mina de urânio

    During a mine exploration the environment can be affected by different ways being one of them the mine acid drainage(DAM), that is formed by the exposition of sulphated minerals to the atmospheric air, water and iron-oxidation microorganisms. This exposition results in oxidation reactions and formation of sulphuric acid that dissolves all kind of metals present at the mineral that will result in the contamination of the ground and waters. The object of this research work is to test a technological solution of the mine acid drainage problem applying ozone advanced oxidation of the heavy metals present at the mine drainage of a uranium mine with special focus in the manganese removal. This study is applied to the material from the uranium mine of the Brazilian Nuclear Industry - INB, at Caldas- MG. The INB Industry has serious DAM contamination being the main contaminants of the superficial waters the elements, aluminium (Al), manganese (Mn), zinc (Zn), iron (Fe), sulfates(SO{sub 4}{sup +2}), fluorides(F-), rare earth metals besides uranium (U) and thorium (Th). The Caldas unity is being used as research and testing field for the treatment of areas with environment degradation formed by the mining activity. The ozone testing showed a high efficiency for the removal of iron(Fe), manganese(Mn) and cerium (Ce) up to 99%. The manganese total concentration was reduced to values bellow the ones determined by CONAMA resolution. Elements as neodymium (Nd), zinc (Zn) and lanthanium (La) are also oxidated in presence of ozone but with lower efficiency. The aluminium remained unaffected by the ozone while Thorium and Uranium show an initial decay but at the end present only a concentration slight lower than the initial. The solid material formed after the ozone treatment consists mainly of manganese oxide (85%). In order to dispose, after the ozonization, the liquid effluent to the environment is necessary a pH correction in order to be within the CONAMA legislation, being used less reagent (CaOH{sub 2}), 50 to 86% less, than the amounts used in the process adopted by INB.

    Although the beneficial effects (e.g., lipid-lowering activity) of γ-oryzanol (OZ), a mixture of ferulic acid esters of plant sterols and triterpene alcohols, have been extensively investigated, few studies have evaluated the absorption and metabolism of OZ. Moreover, it is unclear whether OZ, once ingested, is directly absorbed by the intestine into the bloodstream at a sufficient level to exhibit activity. Here, we prepared OZ concentrate from purified rice bran oil (Rice Oil OZ), determined the concentration of OZ in the preparation (cycloartenyl ferulate equivalent concentration; 52.2%), and then carried out chromatography-mass spectrometry analysis of plasma samples from mice after oral administration of Rice Oil OZ. The OZ concentrations of plasma from the control (vehicle-treated) mice were low (trace levels); however, at 5 h after a single oral administration of the Rice Oil OZ (600 mg per kg body weight), the levels significantly increased, reaching 17.6 ng mL -1 for cycloartenyl ferulate, 28.2 ng mL -1 for 24-methylenecycloartanyl ferulate isomers, 15.6 ng mL -1 for campesteryl ferulate, and 5.1 ng mL -1 for β-sitosteryl ferulate, respectively, expressed in equivalence of cycloartenyl ferulate in plasma. These results provided the first mass spectrometric evidence suggesting that a portion of orally administered OZ is directly absorbed by the intestine and is present in the intact form in plasma. The presence of a significant amount of OZ in its intact form in plasma may explain the beneficial effects of OZ in vivo.

  19. Octazethrene and Its Isomer with Different Diradical Characters and Chemical Reactivity: The Role of the Bridge Structure

    KAUST Repository

    Hu, Pan

    2016-03-11

    The fundamental relationship between structure and diradical character is important for the development of open-shell diradicaloid-based materials. In this work, we synthesized two structural isomers bearing a 2,6-naphthoquinodimethane or a 1,5-naphthoquinodimethane bridge and demonstrated that their diradical characters and chemical reactivity are quite different. The mesityl or pentafluorophenyl substituted octazethrene derivatives OZ-M/OZ-F and their isomer OZI-M (with mesityl substituents) were synthesized via an intramolecular Friedel-Crafts alkylation followed by oxidative dehydrogenation strategy from the key building blocks 4 and 11. Our detailed experimental and theoretical studies showed that both isomers have an open-shell singlet ground state with a remarkable diradical character (y0 = 0.35 and 0.34 for OZ-M and OZ-F, and y0 = 0.58 for OZI-M). Compounds OZ-M and OZ-F have good stability under the ambient environment while OZI-M has high reactivity and can be easily oxidized to a dioxo-product 15, which can be correlated to their different diradical characters. Additionally, we investigated the physical properties of OZ-M, OZ-F and 15.

    In this study, a high-gravity rotating packed bed (HGRPB or HG) was used as a catalytic ozonation (Cat-OZ) reactor to decompose phenol. The operation of HGRPB system was carried out in a semi-batch apparatus which combines two major parts, namely the rotating packed bed (RPB) and photo-reactor (PR). The high rotating speed of RPB can give a high volumetric gas-liquid mass transfer coefficient with one or two orders of magnitude higher than those in the conventional packed beds. The platinum-containing catalyst (Dash 220N, Pt/γ-Al 2 O 3 ) and activated alumina (γ-Al 2 O 3 ) were packed in the RPB respectively to adsorb molecular ozone and the target pollutant of phenol on the surface to catalyze the oxidation of phenol. An ultra violet (UV) lamp (applicable wavelength λ = 200-280 nm) was installed in the PR to enhance the self-decomposition of molecular ozone in water to form high reactive radical species. Different combinations of advanced oxidation processes (AOPs) with the HGRPB for the degradation of phenol were tested. These included high-gravity OZ (HG-OZ), HG catalytic OZ (HG-Cat-OZ), HG photolysis OZ (HG-UV-OZ) and HG-Cat-OZ with UV (HG-Cat-UV-OZ). The decomposition efficiency of total organic compound (η TOC ) of HG-UV-OZ with power of UV (P UV ) of 16 W is 54% at applied dosage of ozone per volume sample m A,in = 1200 mg L -1 (reaction time t = 20 min), while that of HG-OZ without the UV irradiation is 24%. After 80 min oxidation (m A,in = 4800 mg L -1 ), the η TOC of HG-UV-OZ is as high as 94% compared to 82% of HG-OZ process. The values of η TOC for HG-Cat-OZ process with m S = 42 g are 56% and 87% at m A,in = 1200 and 4800 mg L -1 , respectively. By increasing the catalyst mass to 77 g, the η TOC for the HG-Cat-OZ process reaches 71% and 90% at m A,in = 1200 and 4800 mg L -1 , respectively. The introduction of Pt/γ-Al 2 O 3 as well as UV irradiation in the HG-OZ process can enhance the η TOC of phenol significantly, while γ-Al 2 O 3 exhibits

    The high morbidity of metabolic dysfunction diseases has heightened interest in seeking natural and safe compounds to maintain optimal health. γ-Oryzanol (OZ), the ferulic acid (FA) ester with phytosterols, mainly present in rice bran has been shown to improve markers of metabolic syndrome. This study investigates the effects of FA and OZ on alleviating high-fat and high-fructose diet (HFFD)-induced metabolic syndrome parameters. Male SD rats were fed with a regular rodent diet, HFFD, or HFFD supplemented with 0.05% FA or 0.16% OZ (equimolar concentrations) for 13 weeks. Food intake, organ indices, serum lipid profiles, glucose metabolism, insulin resistance (IR) index and cytokine levels were analyzed. The mechanisms were further investigated in oleic acid-stimulated HepG2 cells by analyzing triglyceride (TG) content and lipogenesis-related gene expressions. In the in vivo study, FA and OZ exhibited similar effects in alleviating HFFD-induced obesity, hyperlipidemia, hyperglycemia, and IR. However, only OZ treatment significantly decreased liver index and hepatic TG content, lowered serum levels of C-reactive protein and IL-6, and increased serum concentration of adiponectin. In the in vitro assay, only OZ administration significantly inhibited intracellular TG accumulation and down-regulated expression of stearoyl coenzyme-A desaturase-1, which might facilitate OZ to enhance its hepatoprotective effect. OZ is more effective than FA in inhibiting hepatic fat accumulation and inflammation. Thus, FA and OZ could be used as dietary supplements to alleviate the deleterious effects of HFFD.

    The Bureau of Mines, investigated a cyanidation-carbon adsorption technique for extracting gold from arsenopyrite concentrates. Agitation leach experiments were conducted on 85%-minus-35-mesh gravity concentrates containing 21.8 oz gold and 6.4 oz silver per ton. Results obtained in leaching the concentrates showed that 96.9% gold and 90.7% silver extraction could be achieved in 96 hours of agitation. Gold and silver were recovered from the resulting pregnant solution by exposure to granular activated carbon in a countercurrent system. Carbon loadings of 2556 oz of gold and 502 oz of silver per ton were achieved. These loadings are significantly higher than heretofore thought practical.

  4. Validation of the 2nd Generation Proteasome Inhibitor Oprozomib for Local Therapy of Pulmonary Fibrosis.

    Directory of Open Access Journals (Sweden)

    Nora Semren

    Full Text Available Proteasome inhibition has been shown to prevent development of fibrosis in several organs including the lung. However, effects of proteasome inhibitors on lung fibrosis are controversial and cytotoxic side effects of the overall inhibition of proteasomal protein degradation cannot be excluded. Therefore, we hypothesized that local lung-specific application of a novel, selective proteasome inhibitor, oprozomib (OZ, provides antifibrotic effects without systemic toxicity in a mouse model of lung fibrosis. Oprozomib was first tested on the human alveolar epithelial cancer cell line A549 and in primary mouse alveolar epithelial type II cells regarding its cytotoxic effects on alveolar epithelial cells and compared to the FDA approved proteasome inhibitor bortezomib (BZ. OZ was less toxic than BZ and provided high selectivity for the chymotrypsin-like active site of the proteasome. In primary mouse lung fibroblasts, OZ showed significant anti-fibrotic effects, i.e. reduction of collagen I and α smooth muscle actin expression, in the absence of cytotoxicity. When applied locally into the lungs of healthy mice via instillation, OZ was well tolerated and effectively reduced proteasome activity in the lungs. In bleomycin challenged mice, however, locally applied OZ resulted in accelerated weight loss and increased mortality of treated mice. Further, OZ failed to reduce fibrosis in these mice. While upon systemic application OZ was well tolerated in healthy mice, it rather augmented instead of attenuated fibrotic remodelling of the lung in bleomycin challenged mice. To conclude, low toxicity and antifibrotic effects of OZ in pulmonary fibroblasts could not be confirmed for pulmonary fibrosis of bleomycin-treated mice. In light of these data, the use of proteasome inhibitors as therapeutic agents for the treatment of fibrotic lung diseases should thus be considered with caution.

    The peroxide bond of the artemisinins inspired the development of a class of fully synthetic 1,2,4-trioxolane-based antimalarials, collectively known as the ozonides. Similar to the artemisinins, heme-mediated degradation of the ozonides generates highly reactive radical species that are thought to mediate parasite killing by damaging critical parasite biomolecules. We examined the relationship between parasite dependent degradation and antimalarial activity for two ozonides, OZ277 (arterolane) and OZ439 (artefenomel), using a combination of in vitro drug stability and pulsed-exposure activity assays. Our results showed that drug degradation is parasite stage dependent and positively correlates with parasite load. Increasing trophozoite-stage parasitemia leads to substantially higher rates of degradation for both OZ277 and OZ439, and this is associated with a reduction in in vitro antimalarial activity. Under conditions of very high parasitemia (∼90%), OZ277 and OZ439 were rapidly degraded and completely devoid of activity in trophozoite-stage parasite cultures exposed to a 3-h drug pulse. This study highlights the impact of increasing parasite load on ozonide stability and in vitro antimalarial activity and should be considered when investigating the antimalarial mode of action of the ozonide antimalarials under conditions of high parasitemia.

    γ-oryzanol (OZ) is a rich source of commercially-important bioactive phytochemicals, most of them of interest in nutrition, pharmacy and cosmetics. However, the poor solubility of OZ limited the use. In the paper, ultraviolet-visible (UV-Vis) analysis was conducted to analysis the solubilization of OZ under combined use of Tween 80 in vitro. In addition, to further confirm the solubilizing effect of Tween 80, a pharmacokinetic study of ferulic acid (FA) in rats after oral administration of OZ 100 mg/kg under combined use of Tween 80 though LCMS/MS was carried out. Solubility enhancement as high as 100-fold is achieved using 1% Tween 80 in vitro. Following oral administration of OZ-Tween 80 100 mg/kg, the values of Tmax, Cmax, AUC0-∞, T1/2Ka and MRT0-∞ were 46.667 ± 39.328, 129.498 ± 27.025, 63738.28 ± 599, 14.274 ± 7.309 and 859.592 ± 108.780 respectively. The values of T1/2Ka, AUC0-∞, MRT0-t, and Tmax showed up to increase 16%, 58%, 44% and 47% while Cmax and CL/F decreased 22% and 12%, respectively. The decreased Cmax value indicated that Tween 80 can hardly enhance the absorption of FA in rats. However, T1/2Ka and Tmax values showed that the absorption of FA was extended, which resulted the increased values of AUC0-∞ and MRT0-∞. Our results reveal that Tween 80 improves solubility of OZ in vitro and could enhance the bioavailability of OZ by extending its absorption and elimination.

    1976-01-01

    Purpose: To dispense with frequent running of detector in a BWR type reactor and permit calculation of the prevailing value and forecast value of power distribution in a specified region in an on-line basis. Constitution: The prevailing power distribution P sub(OZ) (where Z indicates a position in the axial direction) at a given position is estimated by prevailing power distribution estimating means, and the average prevailing power distribution Q sub(OZ) in the core is estimated while making correction of a primary neutron distribution model by core average characteristic measuring means. Then, the estimated core average power distribution Q sub(Z) after alteration of the core flow rate or alteration of Xe concentration is estimated by core average power distribution estimating means. At this time, a forecast power distribution P sub(Z) in a specified region after alteration of the flow rate or alteration of the Xe concentration is calculated on the basis of a relation P sub(Z) = (Q sub(Z)/Q sub(OZ)) by using P sub(OZ), Q sub(OZ) and Q sub(Z). The above calculations are carried out in a short period of time by using a process computer. (Ikeda, J.)

    A bridge function approximation is proposed to close the Ornstein-Zernike (OZ) integral equation for fluids with purely repulsive potentials. The performance of the bridge function approximation is then tested by applying the approximation to two kinds of repulsive potentials, namely, the square shoulder potential and the triangle shoulder potential. An extensive comparison between simulation and the OZ approach is performed over a wide density range for the fluid phase and several temperatures. It is found that the agreement between the two routes is excellent for not too low temperatures and satisfactory for extremely low temperatures. Then, this globally trustworthy OZ approach is used to investigate the possible existence or not of a liquid anomaly, i.e., a liquid-liquid phase transition at low temperatures and negative values of the thermal expansion coefficient in certain region of the phase diagram. While the existence of the liquid anomaly in the square shoulder potential has been previously predicted by a traditional first-order thermodynamic perturbation theory (TPT), the present investigation indicates that the liquid-liquid phase transition disappears in the OZ approach, so that its prediction by the first-order TPT is only an artifact originating from the low temperature inadequacy of the first-order TPT. However, the OZ approach indeed predicts negative thermal expansion coefficients. The present bridge function approximation, free of adjustable parameters, is suitable to be used within the context of a recently proposed nonhard sphere perturbation scheme.

    Common ketonization catalysts such as ZrO2, CeO2, CexZryOz, and TiO2-based catalysts have been reported to lose surface area, undergo phase-transformation, and lose catalytic activity when utilized in the condensed aqueous phase. In this work, we synthesized and tested a series of LaxZryOz mixed metal oxides with different La:Zr atomic ratios with the goal of enhancing the catalytic activity and stability for the ketonization of acetic acid in condensed aqueous media at 568 K. We synthesized a hydrothermally stable LaxZryOz mixed-metal oxide catalyst with enhanced ketonization activities 360 and 40 times more active than La2O3 and ZrO2, respectively. Catalyst characterization techniques suggest that the formation of a hydrothermally stable catalyst which is isomorphic with tetragonal-ZrO2 under hydrothermal reaction conditions.

    Full Text Available Background: The high consumption of fat and sugar contributes to the development of obesity and co-morbidities, such as diabetes, and cardiovascular and kidney diseases. Different strategies have been used to prevent these diseases associated with obesity, such as changes in eating habits and/or the addition of dietary components with anti-inflammatory and anti-oxidant properties, such as gamma-oryzanol (γOz present mainly in bran layers and rice germ. Methods: Animals were randomly divided into four experimental groups and fed ad libitum for 20 weeks with control diet (C, n = 8, control diet + γOz (C + γOz, n = 8, high-sugar and high-fat diet (HSF, n = 8, and high-sugar and high-fat diet + γOz (HSF + γOz, n = 8. HSF groups also received water + sucrose (25%. The dose of γOz was added to diets to reach 0.5% of final concentration (w/w. Evaluation in animals included food and caloric intake, body weight, plasma glucose, insulin, triglycerides, uric acid, HOMA-IR, glomerular filtration rate, protein/creatinine ratio, systolic blood pressure, and Doppler echocardiographic. Results: Animals that consumed the HSF diet had weight gain compared to group C, increased insulin, HOMA, glucose and triglycerides, there were also atrial and ventricular structural alterations, deterioration of systolic and diastolic function, decreased glomerular filtration rate, and proteinuria. Gamma-oryzanol is significantly protective against effects on body weight, hypertriglyceridemia, renal damage, and against structural and functional alteration of the heart. Conclusion: Gamma-oryzanol shows potential as a therapeutic to prevent Cardiorenal Metabolic Syndrome.

    Accurate methods of assessing food intake in infants are needed to assess the relationship between infant feeding practices and risk of childhood obesity. Current methods are either subjective or have limited ability for use beyond clinical research settings. To assess the accuracy of the RFPM to evaluate simulated milk intake including energy, macronutrient, and micronutrient intake compared to direct weighing within a controlled study. Individuals were recruited to prepare three 2 fl oz, 4 fl oz, 6 fl oz, and 8 fl oz servings of infant formula and to capture photographs at different stages of preparation (dry powdered formula, prepared formula, and liquid waste) using the SmartIntake® application. Gram weights of the bottles were obtained by the RFPM and direct weighing. Using the United States Department of Agriculture National Nutrient Database for Standard Reference, energy, macronutrient, and micronutrient values were generated from gram weights. Intake of formula prepared from powder measured by the RFPM was equivalent to weighed intake within 7.5% equivalence bounds among all servings and each serving size. The mean difference between methods varied among servings sizes with the RFPM underestimating intake by 1.6 ± 0.4 kcals in 2 fl oz servings, 4.8 ± 0.6 kcals in 4 fl oz servings, and 6.2 ± 1.0 kcals in 6 fl oz servings, and overestimating intake by 0.1 ± 1.2 kcals in 8 fl oz servings. Bland-Altman analysis showed that the RFPM overestimated intake at lower levels food intake and underestimated intake at higher levels. Considering photographs of only the prepared formula bottle and the bottle with formula waste to simulate ready-to-feed formula and human breast milk, intake estimated by the RFPM was equivalent to the directly weighed intake within 7.5% for all servings. The RFPM has higher accuracy than subjective methods and similar accuracy as compared to the objective methods in estimating simulated intake of milk and formula with lower burden to

  20. Ozone-induced dissociation on a traveling wave high-resolution mass spectrometer for determination of double-bond position in lipids.

    2017-09-15

    The position of C=C within fatty acyl chains affects the biological function of lipids. Ozone-induced dissociation mass spectrometry (OzID-MS) has great potential in determination of lipid double-bond position, but has generally been implemented on low-resolution ion trap mass spectrometers. In addition, most of the OzID-MS experiments carried out so far were focused on the sodiated adducts of lipids; fragmentation of the most commonly observed protonated ions generated in LC/MS-based lipidomics workflow has been less explored. Ozone generated in line from an ozone generator was connected to the trap and transfer gas supply line of a Synapt G2 high-resolution mass spectrometer. Protonated ions of different phosphatidylcholines (PC) were generated by electrospray ionization through direct infusion. Different parameters, including traveling wave height and velocity, trap entrance and DC potential, were adjusted to maximize the OzID efficiency. sn-positional isomers and cis/trans isomers of lipids were compared for their reactivity with ozone. Traveling wave height and velocity were tuned to prolong the encounter time between lipid ions and ozone, and resulted in improved OzID efficiency, as did increasing trapping region DC and entrance potential. Under optimized settings, at least 1000 times enhancement in OzID efficiency was achieved compared to that under default settings for monounsaturated PC standards. Monounsaturated C=C in the sn-2 PC isomer reacted faster with ozone than the sn-1 isomer. Similarly, the C=C in trans PC reacted faster than in cis PC. This is the first implementation of OzID in the trap and transfer region of a traveling wave enabled high-resolution mass spectrometer. The OzID reaction efficiency is significantly improved by slowing down ions in the trap region for their prolonged interaction with ozone. This will facilitate application of high-resolution OzID-MS in lipidomics. Copyright © 2017 John Wiley & Sons, Ltd.

    Ornstein-Zernike (OZ)-type theory is a powerful tool to obtain 3-dimensional solvent distribution around solute molecule. Recently, we proposed multi-center molecular OZ method, which is suitable for parallel computing of 3D solvation structure. The distribution function in this method consists of two components, namely reference and residue parts. Several types of the function were examined as the reference part to investigate the numerical robustness of the method. As the benchmark, the method is applied to water, benzene in aqueous solution and single-walled carbon nanotube in chloroform solution. The results indicate that fully-parallelization is achieved by utilizing the newly proposed reference functions.

  7. Kinetically blocked stable heptazethrene and octazethrene: Closed-shell or open-shell in the ground state?

    KAUST Repository

    Li, Yuan

    2012-09-12

    Polycyclic aromatic hydrocarbons with an open-shell singlet biradical ground state are of fundamental interest and have potential applications in materials science. However, the inherent high reactivity makes their synthesis and characterization very challenging. In this work, a convenient synthetic route was developed to synthesize two kinetically blocked heptazethrene (HZ-TIPS) and octazethrene (OZ-TIPS) compounds with good stability. Their ground-state electronic structures were systematically investigated by a combination of different experimental methods, including steady-state and transient absorption spectroscopy, variable temperature NMR, electron spin resonance (ESR), superconducting quantum interfering device (SQUID), FT Raman, and X-ray crystallographic analysis, assisted by unrestricted symmetry-broken density functional theory (DFT) calculations. All these demonstrated that the heptazethrene derivative HZ-TIPS has a closed-shell ground state while its octazethrene analogue OZ-TIPS with a smaller energy gap exists as an open-shell singlet biradical with a large measured biradical character (y = 0.56). Large two-photon absorption (TPA) cross sections (σ(2)) were determined for HZ-TIPS (σ(2)max = 920 GM at 1250 nm) and OZ-TIPS (σ(2)max = 1200 GM at 1250 nm). In addition, HZ-TIPS and OZ-TIPS show a closely stacked 1D polymer chain in single crystals. © 2012 American Chemical Society.

    Importance Data are needed to evaluate community interventions to reduce consumption of sugary drinks. Supermarket sales data can be used for this purpose. Objective To compare beverage sales in Howard County, Maryland (HC), with sales in comparison stores in a contiguous state before and during a 3-year campaign to reduce consumption of sugary beverages. Design, Setting, and Partipicants This observational experiment with a control group included 15 HC supermarkets and 17 comparison supermarkets. Weekly beverage sales data at baseline (January 1 to December 31, 2012) and from campaign years 1 to 3 (January 1, 2013, through December 31, 2015) were analyzed. A difference-in-differences (DID) regression compared the volume sales per product per week in the HC and comparison stores, controlling for mean product price, competitor’s product price, product size, weekly local temperature, and manufacturer. Exposures The campaign message was to reduce consumption of all sugary drinks. Television advertising, digital marketing, direct mail, outdoor advertising, social media, and earned media during the 3-year period created 17 million impressions. Community partners successfully advocated for public policies to encourage healthy beverage consumption in schools, child care, health care, and government settings. Main Outcomes and Measures Sales were tracked of sugary drinks highlighted in the campaign, including regular soda, sports drinks, and fruit drinks. Sales of diet soda and 100% juice were also tracked. Sales data are expressed as mean fluid ounces sold per product, per store, per week. Results Regular soda sales in the 15 HC supermarkets decreased (−19.7%) from 2012 through 2015, whereas sales remained stable (0.8%) in the 17 comparison supermarkets (DID adjusted mean, −369 fl oz; 95% CI, −469 to −269 fl oz; P < .01). Fruit drink sales decreased (−15.3%) in HC stores and remained stable (−0.6%) in comparison stores (DID adjusted mean, −342 fl oz

  19. Caloric effect of a 16-ounce (473-mL) portion-size cap on sugar-sweetened beverages served in restaurants.

    2013-08-01

    New York City recently proposed a restriction to cap the portion size of all sugar-sweetened beverages (SSBs) sold in food-service establishments at 16 oz (473 mL). One critical question is whether such a policy may disproportionally affect low-income or overweight individuals. The objective was to determine the demographic characteristics of US individuals potentially affected by a 16-oz portion-size cap on SSBs and the potential effect on caloric intake. We analyzed dietary records from the NHANES 2007-2010. We estimated the proportion of individuals who consumed at least one SSB >16 fluid oz (473 mL) in restaurants by age, household income, and weight status. Of all SSBs >16 oz (473 mL) purchased from food-service establishments, 64.7% were purchased from fast food restaurants, 28.2% from other restaurants, and 4.6% from sports, recreation, and entertainment facilities. On a given day, the policy would affect 7.2% of children and 7.6% of adults. Overweight individuals are more likely to consume these beverages, whereas there was no significant difference between income groups. If 80% of affected consumers choose a 16-oz (473-mL) beverage, the policy would result in a change of -57.6 kcal in each affected consumer aged 2-19 y (95% CI: -65.0, -50.1) and -62.6 kcal in those aged ≥20 y (95% CI: -67.9, -57.4). A policy to cap portion size is likely to result in a modest reduction in excess calories from SSBs, especially among young adults and children who are overweight.

    While general consensus holds that food portion sizes are increasing, no empirical data have documented actual increases. To determine trends in food portion sizes consumed in the United States, by eating location and food source. Nationally representative data from the Nationwide Food Consumption Survey (1977-1978) and the Continuing Survey of Food Intake by Individuals (1989-1991, 1994-1996, and 1998). The sample consists of 63 380 individuals aged 2 years and older. For each survey year, average portion size consumed from specific food items (salty snacks, desserts, soft drinks, fruit drinks, french fries, hamburgers, cheeseburgers, pizza, and Mexican food) by eating location (home, restaurant, or fast food). Portion sizes vary by food source, with the largest portions consumed at fast food establishments and the smallest at other restaurants. Between 1977 and 1996, food portion sizes increased both inside and outside the home for all categories except pizza. The energy intake and portion size of salty snacks increased by 93 kcal (from 1.0 to 1.6 oz [28.4 to 45.4 g]), soft drinks by 49 kcal (13.1 to 19.9 fl oz [387.4 to 588.4 mL]), hamburgers by 97 kcal (5.7 to 7.0 oz [161.6 to 198.4 g]), french fries by 68 kcal (3.1 to 3.6 oz [87.9 to 102.1 g]), and Mexican food by 133 kcal (6.3 to 8.0 oz [178.6 to 226.8 g]). Portion sizes and energy intake for specific food types have increased markedly with greatest increases for food consumed at fast food establishments and in the home.

  2. Online Ozonolysis Combined with Ion Mobility-Mass Spectrometry Provides a New Platform for Lipid Isomer Analyses

    One of the most significant challenges in contemporary lipidomics lies in the separation and identification of lipid isomers that differ only in site(s) of unsaturation or geometric configuration of the carbon-carbon double bonds. While analytical separation techniques including ion mobility spectrometry (IMS) and liquid chromatography (LC) can separate isomeric lipids under appropriate conditions, conventional tandem mass spectrometry cannot provide unequivocal identification. To address this challenge, we have implemented ozone-induced dissociation (OzID) in-line with LC, IMS and high resolution mass spectrometry. Modification of an IMS- capable quadrupole time-of-flight mass spectrometer was undertaken to allow the introduction of ozone into the high-pressure trapping ion funnel region preceding the IMS cell. This enabled the novel LC-OzID-IMS-MS configuration where ozonolysis of ionized lipids occurred rapidly (10 ms) without prior mass-selection. LC-elution time alignment combined with accurate mass and arrival time extraction of ozonolysis products facilitated correlation of precursor and product ions without mass-selection (and associated reductions in duty cycle). Unsaturated lipids across 11 classes were examined using this workflow in both positive and negative ion modalities and in all cases the positions of carbon-carbon double bonds were unequivocally assigned based on predictable OzID transitions. Under these conditions geometric isomers exhibited different IMS arrival time distributions and distinct OzID product ion ratios providing a means for discrimination of cis/trans double bonds in complex lipids. The combination of OzID with multidimensional separations shows significant promise for facile profiling of unsaturation patterns within complex lipidomes.

    Data are needed to evaluate community interventions to reduce consumption of sugary drinks. Supermarket sales data can be used for this purpose. To compare beverage sales in Howard County, Maryland (HC), with sales in comparison stores in a contiguous state before and during a 3-year campaign to reduce consumption of sugary beverages. This observational experiment with a control group included 15 HC supermarkets and 17 comparison supermarkets. Weekly beverage sales data at baseline (January 1 to December 31, 2012) and from campaign years 1 to 3 (January 1, 2013, through December 31, 2015) were analyzed. A difference-in-differences (DID) regression compared the volume sales per product per week in the HC and comparison stores, controlling for mean product price, competitor's product price, product size, weekly local temperature, and manufacturer. The campaign message was to reduce consumption of all sugary drinks. Television advertising, digital marketing, direct mail, outdoor advertising, social media, and earned media during the 3-year period created 17 million impressions. Community partners successfully advocated for public policies to encourage healthy beverage consumption in schools, child care, health care, and government settings. Sales were tracked of sugary drinks highlighted in the campaign, including regular soda, sports drinks, and fruit drinks. Sales of diet soda and 100% juice were also tracked. Sales data are expressed as mean fluid ounces sold per product, per store, per week. Regular soda sales in the 15 HC supermarkets decreased (-19.7%) from 2012 through 2015, whereas sales remained stable (0.8%) in the 17 comparison supermarkets (DID adjusted mean, -369 fl oz; 95% CI, -469 to -269 fl oz; P sports drinks (-86.3 fl oz; 95% CI, -343.6 to 170.9 fl oz) and diet soda (-17.8 in HC stores vs -11.3 in comparison stores; DID adjusted mean, -78.9 fl oz; 95% CI, -182.1 to 24.4 fl oz) decreased in both communities, but the decreases were not significantly

    Whether the temporal correlation between inter-leads Electroencephalogram (EEG) that located on the boundary between left and right brain hemispheres is associated with sleep stages or not is still unknown. The purpose of this paper is to evaluate the role of correlation coefficients between EEG leads Fpz-Cz and Pz-Oz for automatic classification of sleep stages. A total number of 39 EEG recordings (about 20 h each) were selected from the expanded sleep database in European data format for temporal correlation analysis. Original waveform of EEG was decomposed into sub-bands δ (1-4 Hz), θ (4-8 Hz), α (8-13 Hz) and β (13-30 Hz). The correlation coefficient between original EEG leads Fpz-Cz and Pz-Oz within frequency band 0.5-30 Hz was defined as r(EEG) and was calculated every 30 s, while that between the two leads EEG in sub-bands δ, θ, α and β were defined as r(δ), r(θ), r(α) and r(β), respectively. Classification of wakefulness and sleep was processed by fixed threshold that derived from the probability density function of correlation coefficients. There was no correlation between EEG leads Fpz-Cz and Pz-Oz during wakefulness (|r| r > 0.1 for r(EEG) and r(δ)), while low correlation existed during sleep (r ≈ -0.4 for r(EEG), r(δ), r(θ), r(α) and r(β)). There were significant differences (analysis of variance, P correlation index between EEG leads Fpz-Cz and Pz-Oz could distinguish all five types of wakefulness, rapid eye movement (REM) sleep, N1 sleep, N2 sleep and N3 sleep. In conclusion, the temporal correlation between EEG bipolar leads Fpz-Cz and Pz-Oz are highly associated with sleep-wake stages. Moreover, high accuracy of sleep-wake classification could be achieved by the temporal correlation within frequency band 0.5-30 Hz between EEG leads Fpz-Cz and Pz-Oz.

    2013-04-24

    Dielectric/metal/dielectric (DMD) electrodes have the potential to significantly increase the absorption efficiency and photocurrent in flexible organic solar cells. We demonstrate that this enhancement is attributed to a broadband cavity resonance. Silver-based semitransparent DMD electrodes with sheet resistances below 10 ohm/sq. are fabricated on flexible polyethylene terephthalate (PET) substrates in a high-throughput roll-to-roll sputtering tool. We carefully study the effect of the semitransparent DMD electrode (here composed of ZnxSnyOz/Ag/InxSn yOz) on the optical device performance of a copper phthalocyanine (CuPc)/fullerene (C60) bilayer cell and illustrate that a resonant cavity enhanced light trapping effect dominates the optical behavior of the device. © 2013 Optical Society of America.

    Developments of large-scale energy storages with not only low cost and high safety but also abundant metals are significantly demanded. While lithium ion batteries are the most successful method, they cannot satisfy all conditions. Here we show the principle of novel lithium-free secondary oxygen rocking aqueous batteries, in which oxygen shuttles between the cathode and anode composed of iron-based perovskite-related oxides Ca0.5La0.5FeOz (2.5 ≤ z ≤ 2.75 and 2.75 ≤ z ≤ 3.0). Compound Ca0.5La0.5FeOz can undergo two kinds of reduction and reoxidation of Fe4+/Fe3+ and Fe3+/Fe2+, that are accompanied by reversible and repeatable topotactic oxygen extraction and reinsertion during discharge and charge processes.

  9. Object-oriented simulation for the Superconducting Super Collider

    Zhou, Jiasheng; Chung, Moon-Jung

    1992-10-01

    This paper describes the design and implementation of an object-oriented simulation environment called OZ for the Superconducting Super Collider (SSC). The design applies object-oriented technology to data visualization, behavior modelling, dynamic simulation and version control. A meta class structure is proposed to model different types of objects in large systems by their functionality. OZ provides a direct-manipulation user interface which allows the user to visualize the data as an object in the database and interactively model the component of the system. Modelling can be exercised at different levels of the class hierarchy and then can be dynamically bound into a system for simulation. Inheritance is used to derive new configurations of the system or subsystem from the existing one, and specify an object's behavior. Delegation is used to construct a system by instantiating existing objects and ''stealing'' their methods by delegators

    The present work is devoted to the study of bosons evolving in the frozen magnetar's crust endowed with an ultra-strong magnetic field orthogonal to an electric field, both described by periodic functions. We discuss the quantum tunneling process through the one-dimensional potential barrier along Oz. The solutions to the Klein–Gordon equation are expressed in terms of Mathieu's functions which, for computable particle's energy range, are turning from oscillatory to exponentially growing modes along Oz. Within the Jeffreys–Wentzel–Kramers–Brillouin framework, the transmission coefficient is computed for the particle momentum in the middle of the instability range. (paper)

    This pilot study aimed to determine whether raw milk reduces lactose malabsorption and/or lactose intolerance symptoms relative to pasteurized milk. We performed a crossover trial involving 16 adults with self-reported lactose intolerance and lactose malabsorption confirmed by hydrogen (H2) breath testing. Participants underwent 3, 8-day milk phases (raw vs 2 controls: pasteurized, soy) in randomized order separated by 1-week washout periods. On days 1 and 8 of each phase, milk consumption was 473 mL (16 oz); on days 2 to 7, milk dosage increased daily by 118 mL (4 oz), beginning with 118 mL (4 oz) on day 2 and reaching 710 mL (24 oz) on day 7. Outcomes were area under the breath H2 curve (AUC H2) and self-reported symptom severity (visual analog scales: flatulence/gas, audible bowel sounds, abdominal cramping, diarrhea). AUC H2 (mean ± standard error of the mean) was higher for raw vs pasteurized on day 1 (113 ± 21 vs 71 ± 12 ppm·min·10(-2), respectively, P = .01) but not day 8 (72 ± 14 vs 74 ± 15 ppm·min·10(-2), respectively, P = .9). Symptom severities were not different for raw vs pasteurized on day 7 with the highest dosage (P >.7). AUC H2 and symptom severities were higher for both dairy milks compared with soy milk. Raw milk failed to reduce lactose malabsorption or lactose intolerance symptoms compared with pasteurized milk among adults positive for lactose malabsorption. These results do not support widespread anecdotal claims that raw milk reduces the symptoms of lactose intolerance.

    The worksite environment may influence employees' dietary behaviors. Consumption of water and sugar-sweetened beverages (SSBs) affect weight management; however, little research has evaluated the influence of worksite factors on beverage consumption. Our purpose was to determine whether individual and worksite factors are associated with water and SSB intake among overweight and obese employees. Data were collected as part of baseline assessments for a worksite-based, weight-management intervention trial. Height and weight of participants (N = 1,482; 74% female; mean age = 47 y [standard deviation (SD) = 11 y]; mean weight = 208 lbs [SD = 46 lbs]) were assessed, and participants completed a validated beverage intake questionnaire. Environmental characteristics of worksites (N = 28) were audited. A qualitative comparative analysis (QCA) was used to identify worksite conditions that may support healthier beverage intake patterns. Most participants were white (75% of sample) with at least some college education or a college degree (approximately 82% of sample). Mean water and SSB intake were 27 fl oz (SD = 18 fl oz) and 17 fl oz (SD = 18 fl oz), respectively; SSB intake (191 kcal [SD = 218 kcal]) exceeded the recommended discretionary energy intake. Statistical models did not identify any significant predictors of water intake. Female sex and increasing level of education and household income were associated with lower SSB intake; baseline body weight and greater number of worksite water coolers and vending machines were associated with higher SSB intake. The QCA identified worksite type (ie, not manual labor) as a condition necessary for healthier beverage consumption; a worksite break policy of 2 or more per day may lead to unhealthy beverage consumption. Lower SSB consumption was noted among older participants, female participants, and among participants with higher education and income levels. Workplace factors influence beverage consumption among overweight

    To analyse the refractive implications of single-step, transepithelial photorefractive keratectomy (TransPRK) ablations. A simulation for quantifying the refractive implications of TransPRK ablations has been developed. The simulation includes a simple modelling of corneal epithelial profiles, epithelial ablation profiles as well as refractive ablation profiles, and allows the analytical quantification of the refractive implications of TransPRK in terms of wasted tissue, achieved optical zone (OZ) and induced refractive error. Wasted tissue occurs whenever the actual corneal epithelial profile is thinner than the applied epithelial ablation profile, achieved OZ is reduced whenever the actual corneal epithelial profile is thicker than the applied epithelial ablation profile and additional refractive errors are induced whenever the actual difference centre-to-periphery in the corneal epithelial profile deviates from the difference in the applied epithelial ablation profile. The refractive implications of TransPRK ablations can be quantified using simple theoretical simulations. These implications can be wasted tissue (∼14 µm, if the corneal epithelial profile is thinner than the ablated one), reduced OZ (if the corneal epithelial profile is thicker than ablated one, very severe for low corrections) and additional refractive errors (∼0.66 D, if the centre-to-periphery progression of the corneal epithelial profile deviates from the progression of the ablated one). When TransPRK profiles are applied to normal, not previously treated, non-pathologic corneas, no specific refractive implications associated to the transepithelial profile can be anticipated; TransPRK would provide refractive outcomes equal to those of standard PRK. Adjustments for the planned OZ and, in the event of retreatments, for the target sphere can be easily derived.

    The goal of this study was to investigate the impact of energy drinks on haemodynamic and cardiac physiology. Comparisons were made to coffee as well as water consumption. In Protocol #1 the caffeine content was normalized to body weight to represent a controlled environment. Heart rate, blood pressure and cardiac QTc interval were assessed in 15 participants, on 4 days, prior to and for 6·5 h postconsumption of (i) energy drink (2 mg caffeine per kg body weight; low dose), (ii) energy drink (3 mg caffeine per kg body weight; medium dose), (iii) coffee (2 mg caffeine per kg body weight) and (iv) 250 ml water. In Protocol #2, the beverages were consumed in volumes that they are purchased to represent real-life conditions. The aforementioned measurements were repeated in 15 participants following (i) 1 16 oz can of energy drink (16 oz Monster), (ii) 1 24 oz can of energy drink (24 oz Monster), (iii) 1 packet of Keurig K-Cup Starbucks coffee (coffee) and (iv) 250 ml water. The order of the beverages was performed in a randomized double-blinded fashion. For both protocols, QTc interval, heart rate and systolic blood pressure were unchanged in any condition (P>0·05). Diastolic blood pressure and mean blood pressure were slightly elevated in Protocol #1 (P0·05). These findings suggest that acute consumption of these commonly consumed beverages has no negative effect on cardiac QTc interval. © 2016 Scandinavian Society of Clinical Physiology and Nuclear Medicine.

    Tungsten-bearing rocks in the Benton Range Roadless Area occur in tactite lenses within the Paleozoic metasedimentary units that surround and are intruded by Triassic granodiorite of the Benton Range. High anomalous tungsten values were found in the southern part of the study area. Quartz-vein deposits with copper, lead, zinc, and silver may occur within the Jurassic granitic rock in the northwestern part of the area. Stream-sediment and panned-concentrate samples from the northwestern part of the roadless area, reveal anomalous values in a number of elements. Some of these elements are indicative of mineral suites that form by hydrothermal alteration and are potential metallic-ore producers. Metals having anomalous values are antimony, copper, lead, molybdenum, tin, and zinc; their presence suggests the potential for deposits of the lead-zinc-silver or copper-molybdenum type. Molybdenum and lead were identified by geochemical sampling as having low to moderate potential in the roadless area. An estimated 190,000 tons (172,000 t) of subeconomic gold and silver resources are inside the roadless area at the Gold Crown, Gold Webb, and Gold Wedge mines; another 60,000 tons (54,000 t) of subeconomic gold and silver resources are just outside the area at the Tower, Gold Webb, and Gold Wedge mines (table 1). Most of the lode gold and silver deposits are in quartz veins and shear zones. Minor amounts of copper, lead, and zinc occur in some gold deposits. About 2,240 oz (70 kg) of gold, 8,450 oz (260 kg) of silver, and 4,600 lb of lead (2,090 kg) have been produced from the roadless area. In addition, 7,257 oz (226 kg) of gold and 350 oz (11 kg) silver were produced at the Tower mine, near the area.

    Zircons collected from a granitic pluton provide evidence of serial growth events with specific mechanisms, crystallization temperatures and U-Pb ages, revealing details of the sequential formation process from intrusion through emplacement to crystallization/solidification. The events have been identified by: 1) the study of the internal structure of zircon using cathodoluminescence, 2) deriving crystallization temperatures using Ti-in-zircon thermometry of the internal structure and 3) U-Pb age dating of the internal structure. The magmatic zircons from the Toki granite, central Japan, show two kinds in their internal structure: a low luminescence core (LLC) and oscillatory zonation (OZ). The LLC was produced by interfacial reaction-controlled growth in the granitic magma with cooling from about 910 to 760°C. The formation of OZ occurred by diffusion-controlled growth in a cooling magma chamber from about 850 to 690°C. The U-Pb ages derived from the LLC ranges from 74.7 ± 4.2 to 70.5 ± 1.3 Ma, indicating the incipient intrusion timing of the magma into the shallow crust. The OZ ages distribute from 72.7 ± 0.6 to 70.4 ± 1.7 Ma, which mean the timing from emplacement to crystallization/solidification of the granite pluton. Thus, the serial processes from intrusion through emplacement to crystallization/solidification occurred within a few million years. The old LLC and OZ ages are recognized in the western margins of the Toki granite, implying that the magma forming the western margins was the first to intrude, emplace and crystallize/solidify. The western margins with initial intrusion may accompany the crustal assimilation in order to create sufficient magma reservoir space, which is consistent with larger SrI and ASI values found in the western margins of the granite.

    Full Text Available Self-reported dietary assessment methods can be challenging to validate, and reporting errors for those with lower health literacy (HL may be augmented. Interactive multimedia (IMM based questionnaires could help overcome these limitations. The objectives of this investigation are to assess the comparative validity and sensitivity to change of an IMM beverage intake questionnaire (IMM-BEVQ as compared to dietary recalls and determine the impact of HL. Adults completed three 24-h dietary recalls and the IMM-BEVQ at baseline and after a six-month intervention targeting either sugar-sweetened beverages (SSB or physical activity. Correlations and paired-samples t-tests are presented. For validity (n = 273, intake of SSB (mean difference = 10.6 fl oz and total beverage consumption (mean difference = 16.0 fl oz were significantly different (p ≤ 0.001 at baseline between the IMM-BEVQ and dietary recalls for all participants. However, the differences in intake were generally greater in low HL participants than in adequate HL participants. For sensitivity (n = 162, change in SSB intake (mean difference = 7.2 fl oz was significantly different (p ≤ 0.01 between pre-/post-IMM-BEVQ and pre-/post-dietary recalls, but not total beverage intake (mean difference = 7.6 fl oz for all participants. Changes in SSB and total beverage intake were not significantly different for those with adequate HL. The IMM-BEVQ is a valid dietary assessment tool that is as responsive to detecting changes in beverage intake as dietary recalls. However, adults with lower HL may need additional guidance when completing the IMM-BEVQ.

  2. How commercial and ``violent'' video games can promote culturally sensitive science learning: some questions and challenges

    In their paper, Muñoz and El-Hani propose to bring video games into science classrooms to promote culturally sensitive ethics and citizenship education. Instead of bringing "educational" games, Muñoz and El-Hani take a more creative route and include games such as Fallout 3® precisely because they are popular and they reproduce ideological and violent representations of gender, race, class, nationality, science and technology. However, there are many questions that arise in bringing these commercial video games into science classrooms, including the questions of how students' capacities for critical reflection can be facilitated, whether traditional science teachers can take on the role of using such games in their classrooms, and which video games would be most appropriate to use. In this response, I raise these questions and consider some of the challenges in order to further the possibility of implementing Muñoz and El-Hani's creative proposal for generating culturally sensitive science classrooms.

  4. Structural Analysis of Unsaturated Glycosphingolipids Using Shotgun Ozone-Induced Dissociation Mass Spectrometry

    2017-08-01

    Glycosphingolipids are essential biomolecules widely distributed across biological kingdoms yet remain relatively underexplored owing to both compositional and structural complexity. While the glycan head group has been the subject of most studies, there is paucity of reports on the lipid moiety, particularly the location of unsaturation. In this paper, ozone-induced dissociation mass spectrometry (OzID-MS) implemented in a traveling wave-based quadrupole time-of-flight (Q-ToF) mass spectrometer was applied to study unsaturated glycosphingolipids using shotgun approach. Resulting high resolution mass spectra facilitated the unambiguous identification of diagnostic OzID product ions. Using [M+Na]+ adducts of authentic standards, we observed that the long chain base and fatty acyl unsaturation had distinct reactivity with ozone. The reactivity of unsaturation in the fatty acyl chain was about 8-fold higher than that in the long chain base, which enables their straightforward differentiation. Influence of the head group, fatty acyl hydroxylation, and length of fatty acyl chain on the oxidative cleavage of double bonds was also observed. Application of this technique to bovine brain galactocerebrosides revealed co-isolated isobaric and regioisomeric species, which otherwise would be incompletely identified using contemporary collision-induced dissociation (CID) alone. These results highlight the potential of OzID-MS in glycosphingolipids research, which not only provides complementary structural information to existing CID technique but also facilitates de novo structural determination of these complex biomolecules.

    2007-01-01

    Conjugated linoleic acid (CLA) is found primarily in diary and beef products, but the health benefits of CLA can only be realized if they are consumed at much greater levels than a normal healthy dietary intake. We have recently shown that a CLA-rich soy oil can be produced by simple isomerization of linoleic acid in soy oil by photoirradiation. This oil may allow greatly increased dietary CLA without significantly elevating fat intake. The objective of this study was to prepare CLA-rich potato chips by frying in CLA-rich soy oil. Soy oil was photoisomerized in the presence of iodine catalyst with UV/visible light. The irradiated oil was clay processed to remove the residual iodine and this oil was then used to fry potato chips. Oil was extracted from fried chips and analyzed for its CLA content with gas chromatography. A 1-oz serving of CLA-rich potato chips contained approximately 2.4 g CLA as compared to 0.1 g CLA in 3-oz serving of steak fillet and 0.06 g CLA in 8-oz serving of whole milk. The peroxide value of the oil extracted from potato chips was found to be 1 meq/1000 g sample, which was within the acceptable commercial standards. This study may lead to the commercialization of CLA-rich food products.

  6. Differential response to dexamethasone on the TXB2 release in guinea-pig alveolar macrophages induced by zymosan and cytokines

    Full Text Available Glucocorticosteroids reduce the production of inflammatory mediators but this effect may depend on the stimulus. We have compared the time course of the effect of dexamethasone on the thromboxane B2 (TXB2 release induced by cytokine stimulation and zymosan in guinea-pig alveolar macrophages. Interleukin-1β (IL-1β, tumour necrosis factor-α (TNF-α and opsonized zymosan (OZ, all stimulate TXB2 release. High concentrations of dexamethasone (1–10 μM inhibit the TXB2 production induced by both cytokines and OZ, but the time course of this response is different. Four hours of incubation with dexamethasone reduce the basal TXB2 release and that induced by IL-1β and TNF-α, but do not modify the TXB2 release induced by OZ. However, this stimulus was reduced after 24 h incubation. Our results suggest that the antiinflammatory activity of glucocorticosteroids shows some dependence on stimulus and, therefore, may have more than one mechanism involved.

    This study focuses on spatio-temporal evolution of basaltic volcanism in the Central Anatolian post-collisional Quaternary magmatic province which developed along a NE-SW orientation in Turkey. This magmatic province consists of the stratovolcanoes Erciyes (ES) and Hasandag (HS), and the basaltic volcanic fields of Obruk-Zengen (OZ) and Karapınar (KA). The investigated samples range between basic to intermediate in composition (48-56 wt% SiO2), and exhibit calc-alkaline affinity at ES whereas HS, OZ and KA are alkaline in composition. Based on new Ksbnd Ar ages and major element data, the oldest basaltic rock of ES is 1700 ± 40 ka old and exhibits alkaline character, whereas the youngest basaltic trachyandesite is 12 ± 5 ka old and calc-alkaline in composition. Most ES basaltic rocks are younger than 350 ka. All samples dated from HS are alkaline basalts, ranging from 543 ± 12 ka to 2 ± 7 ka old. With the exception of one basalt, all HS basalts are 100 ka or younger in age. Ksbnd Ar ages range from 797 ± 20 ka to 66 ± 7 ka from OZ. All the basalt samples are alkaline in character and are older than the HS alkaline basalts, with the exception of the youngest samples. The oldest and youngest basaltic samples from KA are 280 ± 7 ka and 163 ± 10 ka, respectively, and are calc-alkaline in character. Based on thermobarometric estimates samples from OZ exhibit the highest cpx-liqidus temperature and pressure. For all centers the calculated crystallization depths are between 11 and 28 km and increase from NE to SW. Multistage crystallization in magma chamber(s) located at different depths can explain this range in pressure. Harker variation diagrams coupled with least-squares mass balance calculations support fractional crystallization for ES and, to lesser extend for HS, OZ and KA. All basaltic volcanic rocks of this study are enriched in large-ion lithophile elements (LILE) and light rare earth elements (LREE). The lack of negative anomalies for high field

    Taxes on sugar-sweetened beverages (SSBs) meant to improve health and raise revenue are being adopted, yet evaluation is scarce. This study examines the association of the first penny per ounce SSB excise tax in the United States, in Berkeley, California, with beverage prices, sales, store revenue/consumer spending, and usual beverage intake. Methods included comparison of pre-taxation (before 1 January 2015) and first-year post-taxation (1 March 2015-29 February 2016) measures of (1) beverage prices at 26 Berkeley stores; (2) point-of-sale scanner data on 15.5 million checkouts for beverage prices, sales, and store revenue for two supermarket chains covering three Berkeley and six control non-Berkeley large supermarkets in adjacent cities; and (3) a representative telephone survey (17.4% cooperation rate) of 957 adult Berkeley residents. Key hypotheses were that (1) the tax would be passed through to the prices of taxed beverages among the chain stores in which Berkeley implemented the tax in 2015; (2) sales of taxed beverages would decline, and sales of untaxed beverages would rise, in Berkeley stores more than in comparison non-Berkeley stores; (3) consumer spending per transaction (checkout episode) would not increase in Berkeley stores; and (4) self-reported consumption of taxed beverages would decline. Main outcomes and measures included changes in inflation-adjusted prices (cents/ounce), beverage sales (ounces), consumers' spending measured as store revenue (inflation-adjusted dollars per transaction) in two large chains, and usual beverage intake (grams/day and kilocalories/day). Tax pass-through (changes in the price after imposition of the tax) for SSBs varied in degree and timing by store type and beverage type. Pass-through was complete in large chain supermarkets (+1.07¢/oz, p = 0.001) and small chain supermarkets and chain gas stations (1.31¢/oz, p = 0.004), partial in pharmacies (+0.45¢/oz, p = 0.03), and negative in independent corner stores and

    Older adults constitute a rapidly expanding proportion of the U.S. Contemporary studies note the increasing prevalence of alcohol consumption in this group. Thus, understanding alcohol effects, consumption patterns, and associated risks in aging populations constitute critical areas of study with increasing public health relevance. Participants (n = 643; 292 women; ages 21-70) were community residing adult volunteers. Primary measures of interest included four patterns of alcohol consumption (average [oz./day]; typical quantity [oz./occasion]; frequency [% drinking days]; and maximal quantity [oz.]). Regression analyses explored associations between these measures, age, and relevant covariates. Subsequent between-group analyses investigated differences between two groups of older adults and a comparator group of younger adults, their adherance to "low-risk" guidelines, and whether alcohol-associated risks differed by age and adherence pattern. Average consumption did not vary by age or differ between age groups. In contrast, markedly higher frequencies and lower quantities of consumption were observed with increasing age. These differences persisted across adherence categories and were evident even in the oldest age group. Exceeding "low-risk" guidelines was associated with greater risk for alcohol-related problems among the older groups. These results emphasize the utility of considering underlying constituent patterns of consumption in older drinkers. Findings highlight difficulties in identifying problem drinking among older adults and contribute to the few characterizations of "risky" drinking patterns in this group. Taken together, our data contribute to literatures of import for the design and enhancement of screening, prevention, and education initiatives directed toward aging adults. Copyright © 2018.

  12. Dietary Intakes of EPA and DHA Omega-3 Fatty Acids among US Childbearing-Age and Pregnant Women: An Analysis of NHANES 2001-2014.

    The 2015–2020 Dietary Guidelines for Americans (DGA) recommend that the general population should consume about 8 ounces (oz.) per week of a variety of seafood, providing approximately 250 mg per day of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), and that pregnant and lactating women should consume 8–12 oz. per week of seafood. We determined the usual intakes, percentage not meeting recommendations, and trends in EPA and DHA intakes among childbearing-age and pregnant women (15–44 years of age) using the NHANES cycles 2001–2002 through 2013–2014. For the childbearing-age women, the mean usual intake of seafood was 0.44 ± 0.02 oz. equivalent per day and 100% of the population was below the DGA recommendation. Mean usual intakes of EPA, DHA, and combined EPA and DHA from foods and dietary supplements combined were 26.8 ± 1.4, 62.2 ± 1.9, and 88.1 ± 3.0 mg per day, respectively. Over 95% of the sample did not meet the daily intakes of 250 mg EPA and DHA. Similar results were observed for pregnant women. After controlling for covariates, there were slight but significant increases in EPA and DHA intakes from foods and dietary supplements over the 14-year span among childbearing-age ( p = 0.005) and pregnant women ( p = 0.002). It was estimated that a majority of U.S. childbearing-age and pregnant women consumed significantly lower amounts of seafood than what the DGA recommends, which subsequently leads to low intakes of EPA and DHA; in addition, dietary supplement use has not eliminated the nutrient shortfall.

  13. Protective effect of oryzanol isolated from crude rice bran oil in experimental model of diabetic neuropathy

    Directory of Open Access Journals (Sweden)

    2012-09-01

    Full Text Available Several studies have implicated the involvement of poor glycemic control and oxidative/nitrosative stress in the development of diabetic neuropathic pain, an important microvascular complication affecting more than 50% of diabetic patients. However, lack of understanding of the underlying etiology, development of tolerance, inadequate relief and possible toxicity associated with classical analgesics warrant the investigation of the novel agents. Therefore, the present study was carried out to investigate the effect of oryzanol (OZ, a commercially-important potent antioxidant component isolated from from crude rice bran oil (cRBO, in streptozotocin (STZ-induced diabetic neuropathy in rats. After eight weeks, diabetic rats developed neuropathy which was evident from decreased tail-flick latency (thermal hyperalgesia and increased nociceptive behavior during the formalin test. This was accompanied by decreased motor coordination based on the evaluation of neuromuscular strength. Na+ K+ ATPase, a biochemical marker associated with the development of diabetic neuropathy, was significantly inhibited in the sciatic nerve of diabetic animals. The activities of antioxidant enzymes and lipid peroxidation levels were significantly elevated in diabetic rats, indicating the involvement of oxidative stress in diabetic neuropathy. Chronic treatment with oryzanol (OZ (50 and 100 mg/kg per oral (p.o. and standard drug glibenclamide (Gl (10 mg/kg, p.o. significantly attenuated the behavioral as well as biochemical changes associated with diabetic neuropathy. The findings provide experimental evidence to the protective effects of OZ on hyperglycemia-induced thermal hyperalgesia and oxidative stress which might be responsible for diabetes induced nerve damage.

    2012-10-01

    Working with a magnetic field periodic along Oz and decaying in time, we deal with the Dirac-type equation characterizing the fermions evolving in magnetar's crust. For ultra-relativistic particles, one can employ the perturbative approach, to compute the conserved current density components. If the magnetic field is frozen and the magnetar is treated as a stationary object, the fermion's wave function is expressed in terms of the Heun's Confluent functions. Finally, we are extending some previous investigations on the linearly independent fermionic modes solutions to the Mathieu's equation and we discuss the energy spectrum and the Mathieu Characteristic Exponent.

    Pluto's large moon Charon [radius 606 km; density = 1.70 g cm(exp. -3)] exhibits a striking variety of landscapes. Charon can be divided into two broad provinces separated by a roughly aligned assemblage of ridges and canyons, which span from east to west. North of this tectonic belt is rugged, cratered terrain (Oz Terra); south of it are smoother but geologically complex plains (Vulcan Planum). (All place names here are informal.) Relief exceeding 20 km is seen in limb profiles and stereo topography.

    During the early decades of the 20th century, the Spanish socio-sanitary situation was described as catastrophic, both in the urban as well as in the rural setting. In that context, sanitation emerged as one of the key elements of the regeneration process taken on by hygiene in its role as mediator.

    We report on a platform that augments the natural experience of exploration in diverse indoor and outdoor environments. The system builds on the theme of surprises in terms of user expectations and finding points of interest. It utilizes physical icons as representations of users' interests...... and as notification tokens to alert users when they are within proximity of a surprise. To evaluate the concept, we developed mock-ups, a video prototype and conducted a wizard-of-oz user test for a national park in Denmark....

Frank Baum’s 1900 novel and MGM’s 1939 film, validates one kind of femininity and stigmatizes as masculine, monstrous, and “other” the woman who strays from her gender role.

    We review some recent progress in the analytic solution of integral equations for molecular fluids. The site-site Ornstein-Zernike (SSOZ) equation with approximate closures appropriate to homonuclear diatomic fluids both with and without attractive dispersion-like interactions has recently been solved in closed form analytically. In this paper, the close relationship between the SSOZ equation for homonuclear dumbells and the usual Ornstein-Zernike (OZ) equation for atomic fluids is carefully elucidated. This relationship is a key motivation for the analytic solutions of the SSOZ equation that have been obtained to date. (author)

  12. Can next-generation soil data products improve soil moisture modelling at the continental scale? An assessment using a new microclimate package for the R programming environment

    Science.gov (United States)

    Kearney, Michael R.; Maino, James L.

    2018-06-01

    Accurate models of soil moisture are vital for solving core problems in meteorology, hydrology, agriculture and ecology. The capacity for soil moisture modelling is growing rapidly with the development of high-resolution, continent-scale gridded weather and soil data together with advances in modelling methods. In particular, the GlobalSoilMap.net initiative represents next-generation, depth-specific gridded soil products that may substantially increase soil moisture modelling capacity. Here we present an implementation of Campbell's infiltration and redistribution model within the NicheMapR microclimate modelling package for the R environment, and use it to assess the predictive power provided by the GlobalSoilMap.net product Soil and Landscape Grid of Australia (SLGA, ∼100 m) as well as the coarser resolution global product SoilGrids (SG, ∼250 m). Predictions were tested in detail against 3 years of root-zone (3-75 cm) soil moisture observation data from 35 monitoring sites within the OzNet project in Australia, with additional tests of the finalised modelling approach against cosmic-ray neutron (CosmOz, 0-50 cm, 9 sites from 2011 to 2017) and satellite (ASCAT, 0-2 cm, continent-wide from 2007 to 2009) observations. The model was forced by daily 0.05° (∼5 km) gridded meteorological data. The NicheMapR system predicted soil moisture to within experimental error for all data sets. Using the SLGA or the SG soil database, the OzNet soil moisture could be predicted with a root mean square error (rmse) of ∼0.075 m3 m-3 and a correlation coefficient (r) of 0.65 consistently through the soil profile without any parameter tuning. Soil moisture predictions based on the SLGA and SG datasets were ≈ 17% closer to the observations than when using a chloropleth-derived soil data set (Digital Atlas of Australian Soils), with the greatest improvements occurring for deeper layers. The CosmOz observations were predicted with similar accuracy (r = 0.76 and rmse of ∼0

    Ten Mapuche indians have been studied with the purpose of observing the particularities of mental disorders in this ethnic group, composed of rural migrants. In each case a syndromatic and an etiological diagnosis has been made. Our cases correspond to six women and four men with an average age of 24.5 years. All are single with a low educational level. Our results show a great frequency of the acute oniroid psychotic syndrome. These results agree with a retrospective study made by Muñoz et al (1966) who found the same syndrome in 66.6% of their Mapuche patients against only 16.3% in non Mapuche chilean patients.

    2002-05-15

    We describe the holographic correspondence between field theories and string/M theory, focusing on the relation between compactifications of string/ M theory on Anti-de Sitter spaces and conformal field theories. We review the background for this correspondence and discuss its motivations and the evidence for its correctness. We describe the main results that have been derived from the correspondence in the regime that the field theory is approximated by classical or semiclassical gravity. We focus on the case of the N = 4 supersymmetric gauge theory in four dimensions. These lecture notes are based on the Review written by O. Aharony, S. Gubser, J. Maldacena, H. Ooguri and Y. Oz.

    2010-10-01

    To examine the frequency and circumstances of reported waterborne outbreaks of gastroenteritis in Australia. Examination of data reported to OzFoodNet between 2001 and 2007. During these seven years, 6,515 gastroenteritis outbreaks were reported to OzFoodNet, most of which were classified as being transmitted person-to-person or from an unknown source. Fifty-four (0.83%) outbreaks were classified as either 'waterborne' or 'suspected waterborne', of which 78% (42/54) were attributed to recreational water and 19% (10/54) to drinking water. Of the drinking water outbreaks, implicated pathogens were found on all but one occasion and included Salmonella sp. (five outbreaks), Campylobacter jejuni (three outbreaks) and Giardia (one outbreak). There have been few waterborne outbreaks detected in Australia, and most of those reported have been associated with recreational exposure. However, there are difficulties in identifying and categorising gastroenteritis outbreaks, as well as in obtaining microbiological and epidemiological evidence, which can result in misclassification or underestimation of water-associated events. Gastroenteritis surveillance data show that, among reported water-associated gastroenteritis outbreaks in Australia, recreational exposure is currently more common than a drinking water source. However, ongoing surveillance for waterborne outbreaks is important, especially as drought conditions may necessitate replacement of conventional drinking water supplies with alternative water sources, which could incur potential for new health risks. © 2010 The Authors.

    To assess the efficacy of low-volume powder polyethylene glycol (PEG)-3350 as a sole bowel preparation for colonoscopy. This case series examined 245 consecutive patients (a mixture of inpatients and outpatients undergoing screening colonoscopy) at a hospital endoscopy center over a 2-year period. The patients received powder PEG-3350 in the amount of 204 g dissolved in 32 oz of water and taken in 3 divided doses 1 hour apart with 8 oz of water in between each dose. Colon preparation scores (CPS) were used to assess the quality of colon cleansing. The results obtained from the 245 patients were collated and compared to those of patients receiving sodium phosphate, the historical control. The mean CPS was calculated to be 3.43, with a standard deviation of 1.12. Of the 245 patients, 92 were scored with a grade of 4, and 5 patients had incomplete colonoscopies secondary to failure of bowel preparation (CPS=0). Among the remaining patients, 22 and 26 were graded as poor (CPS=1) or fair (CPS=2) bowel preparations, respectively. The low-volume powder PEG-3350 formula used in our case series showed effective colon cleansing and may be considered for use as a sole bowel preparation.

    The purpose of this study was to evaluate the validity and the reliability of the European Portuguese version of the EAT-10 (P-EAT-10). This research was conducted in three phases: (i) cultural and linguistic adaptation; (ii) feasibility and reliability test; and (iii) validity tests. The final sample was formed by a cohort of 520 subjects. The P-EAT-10 index was compared for socio-demographic and clinic variables. It was also compared for both dysphagic and non-dysphagic groups as well as for the results of the 3Oz wst. Lastly, the P-EAT-10 scores were correlated with the EuroQol Group Portuguese EQ-5D index. The Cronbach's α obtained for the P-EAT-10 scale was 0.952 and it remained excellent even if any item was deleted. The item-total and the intraclass correlation coefficients were very good. The P-EAT-10 mean of the non-dysphagic cohort was 0.56 and that of the dysphagic cohort was 14.26, the mean comparison between the 3Oz wst groups and the P-EAT-10 scores were significant. A significant higher perception of QoL was also found among the non-dysphagic subjects. P-EAT-10 is a valid and reliable measure that may be used to document dysphagia which makes it useful both for screening in clinical practice and in research.

  2. Extraverted children are more biased by bowl sizes than introverts.

    Directory of Open Access Journals (Sweden)

    Koert van Ittersum

    Full Text Available Extraverted children are hypothesized to be most at risk for over-serving and overeating due to environmental cues--such as the size of dinnerware. A within-subject field study of elementary school students found that extraverted children served themselves 33.1% more cereal in larger bowls (16-oz than in smaller (12-oz bowls, whereas introverted children were unaffected by bowl size (+5.6%, ns. However, when children were asked by adults how much cereal they wanted to eat, both extraverted and introverted children requested more cereal when given a large versus small bowl. Insofar as extraverted children appear to be more biased by environmental cues, this pilot study suggests different serving styles are recommended for parents and other caregivers. They should serve extraverts, but allow introverts to serve themselves. Still, since the average child still served 23.2% more when serving themselves than when served by an adult, it might be best for caregivers to do the serving whenever possible--especially for extraverted children.

This final Construction Quality Assurance (CQA) Report provides documentation that Area 2 was constructed in substantial compliance with the Tennessee Department of Environment and Conservation (TDEC) approved design, as indicated and specified in the permit drawings, approved changes, and specifications. This report applies specifically to the Area 2 excavation, compacted clay soil liner, geomembrane liner, granular leachate collection layer, protective soil cover, and the leachate collection system. An ''As-Built'' survey was performed and is included. The drawings provide horizontal and vertical information for Area 2, the anchor trench, the leachate collection pipe, the temporary access road, and cross-sections of Area 2. This report provides documentation of the following items: the excavation activities of Area 2; the maximum recompacted coefficient of hydraulic conductivity or permeability of the soil is less than 1 x 10 -7 centimeters per second (cm/sec); the total thickness of the compacted clay soil liner equals a minimum of 2 feet; a 40 mil impermeable geomembrane (polypropylene) flexible membrane liner (FML) and 16 oz. geotextile fabric was placed in direct contact with the compacted clay soil liner; a 12 inch granular leachate collection layer was installed and covered with a 8 oz. geotextile separation fabric; the installation of the leachate collection piping; and the two foot protective clay soil cover

    2015-12-01

    It has been recommended that beverages other than 100% fruit juice, such as water, be served at meals and snacks for preschool-aged children to reduce excessive energy intake. Using a 2 × 2 × 2 design (between-subjects factor of order and within-subjects factors of beverage type and size), 26 children (3.9 ± 0.6 years of age, 50% female, 73% white, and 88.5% non-Hispanic or Latino) completed four, 20-min snack sessions consisting of 200 g of applesauce, 60 g of graham crackers, and either 6 oz. (approximately 180 g) or 12 oz. (approximately 360 g) of 100% berry fruit juice or water, to examine the influence of 100% fruit juice and the portion size of the provided fruit juice, on beverage, food, and overall snack intake. Mixed-factor analyses of covariance revealed a significant (p snack energy intake, with more overall energy consumed when juice was provided (175.4 ± 50.0 kcal vs. 104.8 ± 62.8 kcal, p snack increased beverage and/or food intake, and serving 100% juice led to greater overall snack energy intake. Future research should examine the role of 100% fruit juice, and beverage portion size, in contributing to excessive daily energy intake in preschool-aged children. Copyright © 2015 Elsevier Ltd.

The aim of this study was to examine the effectiveness and safety of PRK in correction of various strengths of myopia and to assess how much corneal tissue is being removed with one diopter sphere (Dsph correction by using different optical zones (OZ. Methods. A prospective study with a follow-up period of 6 months included 55 patients of which 100 myopic eyes were treated by PRK method (one eye was included in 10 patients. Myopic eyes with a preoperative best corrected visual acuity (BCVA = 1.0 (20/20 were analysed. In order to assess the effectiveness of PRK operated myopic eyes were divided into four groups according to the dioptric power: 1≤ -1.75 Dsph (n = 26; 2 from -2 to -3.75 Dsph (n = 44; 3 from -4 to -6.75 Dsph (n = 23, and 4 ≥ -7 Dsph (n = 7. Myopic eyes with preoperative BCVA ≤ 0.9 (amblyopic eyes were excluded from the study, as well as eyes with astigmatism > -1.5 Dcyl. To assess the effectiveness of PRK we examined the percentage of eyes in the mentioned groups, which derived uncorrected visual acuity (UCVA 6 months after the intervention to the following: a UCVA = 1.0 (20/20 and b UCVA ≥ 0.5 (20/40. To assess the safety of PRK we examined the frequency of intraoperative and postoperative complications. To estimate how much corneal tissue was removed with one Dsph correction by using different OZ, we used preoperative and postoperative (after 6 months central pachymetry values expressed in μm and volume of cornea (central 7 mm expressed in mm³. In that sense, we used only the myopic eyes with clear preoperative spherical refraction. The total number of these eyes was 27, of which 16 eyes were treated using a 6.5 mm OZ and 11 eyes using a 7 mm OZ. Results. Refractive spherical equivalent (RSE for all eyes was in the range from -0.75 to -8.75 Dsph, and preoperative mean

Costi, Phys. Rev.

We answer this criticism. We also compare new NRG results for cB, with cB calculated directly from the low-field conductance, with new higher-order SPT calculations for this quantity, finding excellent agreement for all Ed and for U /πΔ extending into the strong coupling regime.

    Full Text Available During the early decades of the 20th century, the Spanish socio-sanitary situation was described as catastrophic, both in the urban as well as in the rural setting. In that context, sanitation emerged as one of the key elements of the regeneration process taken on by hygiene in its role as mediator. Through the works of hygienists G. de Membrillera and Luis Muñoz Antuñano, published in 1921, we have approached the analysis of the sanitary situation of rural Spain during this period.

The National Cancer Institute method was used to estimate the usual intake of 100% OJ consumption, selected nutrients, and MyPyramid food groups. Percentages of the population below the Estimated Average Requirement were determined. Covariate adjusted logistic regression was used to determine if consumers had a lower odds ratio of being overweight or obese. Usual per capita intake of 100% OJ was 1.7 oz/d. Among consumers, the usual intake of 100% OJ for children (n = 2183; 26.2% of population) was 10.2 oz/d. Consumers had higher (P juice, and whole fruit. Moderate consumption of 100% OJ should be encouraged in children as a component of a healthy diet. Copyright © 2011 Elsevier Inc. All rights reserved.

    We assessed the short-term ability to increase retail prices of the first US 1-cent-per-ounce excise tax on the distribution of sugar-sweetened beverages (SSBs), which was implemented in March 2015 by Berkeley, California. In 2014 and 2015, we examined pre- to posttax price changes of SSBs and non-SSBs in a variety of retailers in Berkeley and in the comparison cities Oakland and San Francisco, California. We examined price changes by beverage, brand, size, and retailer type. For smaller beverages (≤ 33.8 oz), price increases (cents/oz) in Berkeley relative to those in comparison cities were 0.69 (95% confidence interval [CI] = 0.36, 1.03) for soda, 0.47 (95% CI = 0.08, 0.87) for fruit-flavored beverages, and 0.47 (95% CI = 0.25, 0.69) for SSBs overall. For 2-liter bottles and multipacks of soda, relative price increases were 0.46 (95% CI = 0.03, 0.89) and 0.49 (95% CI = 0.21, 0.77). We observed no relative price increases for nontaxed beverages overall. Approximately 3 months after the tax was implemented, SSB retail prices increased more in Berkeley than in nearby cities, marking a step in the causal pathway between the tax and reduced SSB consumption.

    We estimated the strength and direction of the association between product characteristics (beer type, package size, and brand name) and market-area socioeconomic characteristics, and promoted sales of beer in grocery stores. Supermarket scanner data from 64 market areas across the United States over 5 years were used to estimate regression models of the share of beer sales that are promoted, controlling for beer price, packaging, and type; and for market-level age, race/ethnicity, income, unemployment rate, and percentage of the population living in an alcohol control state. Large-volume units, such as 144-oz and 288-oz packages, are more likely to be promoted than smaller package sizes. Malt-liquor beverages are less likely to be promoted than non-malt-liquor beverages. Age, race/ethnicity, income, and geographic location of the market area are not significantly related to promoted beer sales. Marketing research has shown that in-store merchandising and promotions can substantially increase beer sales and that purchasing large package sizes may increase total consumption. Our results suggest that high levels of promoted sales for large-volume beer packages may result in increased beer consumption.

    The Ornstein-Zernike integral equation (OZ equation) has been used to evaluate the distribution function of solvents around solutes, but its numerical solution is difficult for molecules with a complicated shape. This paper proposes a numerical method to directly solve the OZ equation by introducing the 3D lattice. The method employs no approximation the reference interaction site model (RISM) equation employed. The method enables one to obtain the spatial distribution of spherical solvents around solutes with an arbitrary shape. Numerical accuracy is sufficient when the grid-spacing is less than 0.5 Å for solvent water. The spatial water distribution around a propane molecule is demonstrated as an example of a nonspherical hydrophobic molecule using iso-value surfaces. The water model proposed by Pratt and Chandler is used. The distribution agrees with the molecular dynamics simulation. The distribution increases offshore molecular concavities. The spatial distribution of water around 5α-cholest-2-ene (C27H46) is visualized using computer graphics techniques and a similar trend is observed.

    Patient hand hygiene may be a useful strategy to prevent acquisition of pathogens and to reduce the risk for transmission by colonized patients. Several studies demonstrate that patients and long-term-care facility (LTCF) residents may have difficulty using hand hygiene products that are provided; however, none of them measure feasibility for patients to use different hand hygiene products. A convenience sample of 42 hospitalized patients and 46 LTCF residents was assessed for their ability to use 3 hand sanitizer products (8-oz pushdown pump bottle, 2-oz pocket-sized bottle with a reclosable lid, and alcohol-impregnated hand wipes). The time (seconds) required for accessing each product was compared among acute-care patients and LTCF residents. Participants provided feedback on which product they preferred and found easiest to use. Of 88 participants, 86 (97.7%) preferred the pushdown pump, 2 (2.3%) preferred the bottle with the reclosable lid, and none preferred the hand wipes. For both hospitalized patients and LTCF residents, the average time required to access the pushdown pump was significantly less than the time required to access the other products (pushdown pump, 0.45 seconds; bottle with reclosable lid, 3.86 seconds; and wipes, 5.66 seconds; P hand hygiene products for patients and LTCF residents.

    Australia has a thriving Psycho-Oncology research and clinical community. In this article, the Australian health system in which Psycho-Oncology is embedded is described. Clinical Psycho-Oncology services are outlined, in terms of their composition, processes and reach. The development of the internationally ground-breaking Australian Psychosocial guidelines for the care of adults with cancer is described. Two large Psycho-Oncology organisations which are strongly linked to mainstream Oncology organisations are discussed: the Australian Psycho-Oncology Society (OzPos, a primarily clinician-led and focused organisation) and the Psycho-Oncology Co-operative Research Group (PoCoG, a national cancer clinical trial group). OzPos is a special interest group within the Clinical Oncology Society of Australia, while PoCoG is one of 14 cancer clinical trial groups funded by the national government. It is these strong connections with major multidisciplinary cancer organisations, and a culture of collaboration and co-operation, that have made Psycho-Oncology grow and thrive in Australia. Examples of large collaborative programs of Psycho-Oncology research are provided, as well as the mechanisms used to achieve these outcomes.

  15. Chemistry of liquid metal coolants and sensors

    Liquid sodium is the coolant of choice for the current generation fast breeder reactors. When sodium contains low levels of dissolved non-metallic impurities, it is highly compatible with structural steels. When the dissolved oxygen level is high, corrosion and mass transfer in sodium-steel circuits are enhanced and this involves formation of NaxMyOz type of species (M = alloying components in steels). Experience has shown that this enhancement of corrosion in a sodium circuit with all austenitic steel structural materials would not be encountered if oxygen level in sodium is below ~ 5ppm. For understanding this observation, a complete knowledge on the phase diagrams of Na-M-O systems and the thermochemical data of all relevant NaxMyOz compounds is essential. This presentation would highlight the work carried out at IGCAR on the chemistry of liquid sodium and heavy liquid metal coolants. Work carried out on various sensors for their use in these liquid metal circuits would be described and their current status would be discussed

    Dietary iodine is essential for thyroid hormone production. Although U.S. dietary iodine is generally adequate, some groups, especially women of childbearing age, are at risk for mild iodine deficiency. Children's average urinary iodine is higher than that of adults. U.S. dietary iodine sources have not been assessed recently. A survey of iodine content in 20 brands of bread, 18 brands of cows' milk, and eight infant formulae was performed between 2001 and 2002. Three bread varieties contained more than 300 microg iodine per slice. Iodine content in other brands was far lower (mean +/- sd, 10.1 +/- 13.2 microg iodine/slice). All cows' milk samples had at least 88 microg iodine/250 ml, ranging from 88-168 microg (116.0 +/- 22.1 microg/250 ml). Infant formulae values ranged from 16.2 to 56.8 microg iodine/5 oz (23.5 +/- 13.78 microg/5 oz). The public should be aware of the need for adequate dietary iodine intake and should be aware that ingredient lists do not reflect the iodine content of foods.

    The platinum-group metals (PGMs), Ru, Rh, Pd, Os, Ir and Pt, are widely used as catalysts in petroleum and chemical processes. They find wide applications in automotive exhaust-gas control converters and are of immense importance to the electronics industry. They are found in many items of jewellery and serve to an increasing extent as a form of investment. The PGMs are extracted in minute quantities from a limited number of ores, found mainly in S. Africa and the USSR. They are concentrated and separated from each other by elaborate chemical processes. Because of their great intrinsic value (Pt $650 per oz; Rh $1400 per oz), the recycling of the PGMs from literally hundreds of different forms of scrap is an essential factor in the overall management of the PGM economy. In this survey emphasis is placed on the need to tailor the analytical method according to (a) the environment in which the PGMs occur, (b) the individual PGM concentrations, and (c) the desired sensitivity and precision. The factors which determine the choice of chemical, physicochemical and/or instrumental approaches are discussed. They are further commented on in extensive presentations of dissolution and separation techniques and methods for the final measurement of individual PGMs. Appendices are provided which present the compositions and sources of the products most frequently encountered in PGM analysis, along with information on methods of decomposition, separations required, type of separation, and final determination.

  18. Modelling global change impacts on soil carbon contents of agro-silvo-pastoral Mediterranean systems

    2016-04-01

    To assess the impact of climate change on soil organic C (SOC) stocks in agro-silvo-pastoral environments, different models have been applied worldwide at local or regional scales, such as as RothC (Francaviglia et al., 2012) or CENTURY (Alvaro-Fuentes et al., 2012). However, some of these models may require a high number of input parameters or can underestimate the effect of soil depth. CarboSOIL (Muñoz-Rojas et al., 2013) is an empirical model based on regression techniques and developed to predict SOC contents at standard soil depths (0-25, 25-50 and 50-75 cm) under a range of climate and/or land use change scenarios. CarboSOIL has been successfully applied in different Mediterranean areas ,e.g. Southern Spain (Muñoz-Rojas et al., 2013; Abd-Elmabod et al., 2014), Northern Egypt (Muñoz-Rojas et al., 2014) and Italy (Muñoz-Rojas et al., 2015). In this study, CarboSOIL was applied in the Cardeña and Montoro mountain range Natural Park. This area covers 385 km2 and is located within Sierra Morena (Córdoba, South Spain) and has a semiarid Mediterranean climate. It is characterized by agro-silvo-pastoral systems. The Mediterranean evergreen oak woodland (MEOW-dehesa) is savanna-like open woodland ecosystem characterized by silvopastoral uses, being an ancient human modified Mediterranean landscape (Corral-Fernández et al., 2013; Lozano-García and Parras-Alcántara 2013). The most representative soils in the Cardeña and Montoro mountain range Natural Park are Cambisols, Regosols, Leptosols and Fluvisols. These soils are characterized by low fertility, poor physical conditions and marginal capacity for agricultural use, together with low organic matter (OM) content due to climate conditions (semiarid Mediterranean climate) and soil texture (sandy). The model was applied at different soil depths: 0-25, 25-50 and 50-75 cm (Parras-Alcántara et al., 2015) considering land use and climate changes scenarios based on available global climate models (IPPC, 2007).

    Coffee is often perceived as producing greater pharmacological effects than cola. The present study compared the magnitude and rapidity of peak caffeine levels and subjective effects between coffee and cola. Thirteen users of both coffee and cola (mean daily caffeine consumption = 456 mg) ingested 400 mg caffeine via 12 oz unsweetened coffee, 24 oz sugar-free cola or 2 capsules in a random, double-blind, placebo-controlled, within-subjects design. Subjects provided a saliva sample and completed subjective effect scales 15 min before and 30, 60, 90, 120, 180 and 240 min after ingestion. Mean peak saliva caffeine levels did not differ between coffee (9.7 +/- 1.2 micrograms/ml) and cola (9.8 +/- 0.9 micrograms/ml) and appeared to be greater with these beverages than with the capsule (7.8 +/- 0.6 micrograms/ml; p = NS). Saliva caffeine levels peaked at similar times for coffee (42 +/- 5 min) and cola (39 +/- 5 min) but later for capsule (67 +/- 7 min; p = 0.004). There was no main effect of vehicle or interaction of vehicle and drug on magnitude of peak effect or time to peak increase on self-report scales. In summary, peak caffeine absorption, time to peak absorption, and subjective effects do not appear to be influenced by cola vs. coffee vehicle. Perceived differences in the effects of coffee vs. cola may be due to differences in dose, time of day, added sweetener, environmental setting or contingencies.

    Residents of low-income communities often purchase sugar-sweetened beverages (SSBs) at small, neighborhood "corner" stores. Lowering water prices and increasing SSB prices are potentially complementary public health strategies to promote more healthful beverage purchasing patterns in these stores. Sustainability, however, depends on financial feasibility. Because in-store pricing experiments are complex and require retailers to take business risks, we used a simulation approach to identify profitable pricing combinations for corner stores. The analytic approach was based on inventory models, which are suitable for modeling business operations. We used discrete-event simulation to build inventory models that use data representing beverage inventory, wholesale costs, changes in retail prices, and consumer demand for 2 corner stores in Baltimore, Maryland. Model outputs yielded ranges for water and SSB prices that increased water demand without loss of profit from combined water and SSB sales. A 20% SSB price increase allowed lowering water prices by up to 20% while maintaining profit and increased water demand by 9% and 14%, for stores selling SSBs in 12-oz cans and 16- to 20-oz bottles, respectively. Without changing water prices, profits could increase by 4% and 6%, respectively. Sensitivity analysis showed that stores with a higher volume of SSB sales could reduce water prices the most without loss of profit. Various combinations of SSB and water prices could encourage water consumption while maintaining or increasing store owners' profits. This model is a first step in designing and implementing profitable pricing strategies in collaboration with store owners.

    Full Text Available End-user programming (EUP is a common approach for helping ordinary people create small programs for their professional or daily tasks. Since end-users may not have programming skills or strong motivation for learning them, tools should provide what end-users want with minimal costs of learning –i.e., they must decrease the barriers to entry. However, it is often hard to address these needs, especially for fast-evolving domains such as the Web. To better understand these existing and ongoing challenges, we conducted two formative studies with Web users –a semi-structured interview study, and a Wizard-of-Oz study. The interview study identifies challenges that participants have with their daily experiences on the Web. The Wizard-of-Oz study investigates how participants would naturally explain three computational tasks to an interviewer acting as a hypothetical computer agent. These studies demonstrate a disconnect between what end-users want and what existing EUP systems support, and thus open the door for a path towards better support for end user needs. In particular, our findings include: (1 analysis of challenges that end-users experience on the Web with solutions; (2 seven core functionalities of EUP for addressing these challenges; (3 characteristics of non-programmers describing three common computation tasks; (4 design implications for future EUP systems.

    This study determined whether differential kinematics, kinetics, rates of energy use and cardiopulmonary responses occurred during running with water bottles and bottle belt holders compared to running only. Trained runners (N=42; 27.2±6.4 yr) ran on an instrumented treadmill for four conditions in a randomized order: 1) control run (CON); 2) hand-held full water bottle (FULL, 16.9 fluid oz; 454 g); 3) hand-held half-full water bottle (HALF, 8.4 fluid oz.; 227 g); and 4) waist-worn bottle belt holder (BELT; hydration belt; 676 g). Gas exchange was measured using a portable gas analyzer. Kinetic and kinematic responses were determined via standard 3D videographic techniques. Interactions of limb side (right, left) by study condition (CON, FULL, HALF, BELT) were tested for rates of oxygen use and energy expenditure, and kinematic and kinetic parameters. No significant limb side × condition interactions existed for rates of oxygen use or energy expenditure. A significant interaction occurred with sagittal elbow flexion (pwater by hand or on the waist does not significantly change kinematics of running motion, rates of oxygen use and energy expenditure or cardiopulmonary measures over short durations. Runners are likely making adjustments to joint moments and powers that preserve balance and protect the lower extremity joints while maintaining the rates of oxygen use and energy expenditure.

  4. Extraverted Children Are More Biased by Bowl Sizes than Introverts

    2013-01-01

    Extraverted children are hypothesized to be most at risk for over-serving and overeating due to environmental cues – such as the size of dinnerware. A within-subject field study of elementary school students found that extraverted children served themselves 33.1% more cereal in larger bowls (16-oz) than in smaller (12-oz) bowls, whereas introverted children were unaffected by bowl size (+5.6%, ns). However, when children were asked by adults how much cereal they wanted to eat, both extraverted and introverted children requested more cereal when given a large versus small bowl. Insofar as extraverted children appear to be more biased by environmental cues, this pilot study suggests different serving styles are recommended for parents and other caregivers. They should serve extraverts, but allow introverts to serve themselves. Still, since the average child still served 23.2% more when serving themselves than when served by an adult, it might be best for caregivers to do the serving whenever possible – especially for extraverted children.

    The presence of eosinophils in the lumen and mucosa of the intestine is characteristic of both ulcerative colitis (UC) and Crohn's disease (CD). There is evidence of eosinophil activation in the intestine during acute inflammatory episodes of these diseases; these episodes are also characterized by an influx of neutrophils, which have the potential to cause extensive tissue damage. We undertook a study to determine whether eosinophils in contact with colonic epithelial cells produce factors that may attract neutrophils in response to immunological stimulation. Neutrophil chemotactic activity (NCA) and concentrations of three neutrophil-attracting CXC chemokines - CXCL1 (Groα), CXCL5 (Ena78) and CXCL8 (IL8) - were measured in supernatants of T84 colonic epithelial cells and blood eosinophils or eosinophil-like myeloid leukaemia cells (AML14.3D10), alone or in combination. Cells were stimulated with serum-opsonized zymosan (OZ) particles. NCA (Peosinophil co-cultures were significantly higher than in the supernatants of either cell type alone. Release of CXCL1 (Peosinophils but not higher than from OZ-stimulated epithelial cells. Eosinophils and colonic epithelial cells exhibit synergy in production of neutrophil chemoattractants in response to immunological stimulation. This may represent a mechanism for exaggerated recruitment of neutrophils to the intestine in response to acute infection in conditions that are characterized by the presence of eosinophils in the bowel.

    To examine whether changing weigh-in from the same day of the match to the day before the match and prohibiting 6-oz gloves are associated with fatalities in boxing matches sanctioned by the Japan Boxing Commission (JBC). We analyzed the rates of boxing fatalities before and after the two rule changes above via secondary analysis of data. Demographics and boxing records of deceased boxers were examined using descriptive statistics, exact binomial test the Mann-Whitney-Wilcoxon test and Fisher's exact tests. As of this study, a total of 38 boxers (23.9 ± 3.3 years of age) reportedly died due to injuries sustained in JBC-sanctioned boxing matches since 1952. Changing weigh-in to the day before the match or prohibiting 6-oz gloves was not significantly associated with the rates of boxing fatalities 5 years and 10 years before and after the rule changes (p > 0.05). Deceased boxers after these rule changes were significantly older, completed significantly more rounds in the final match, and were significantly less likely to lose the previous match (prior to the final match) and to do so by knockouts (p boxing fatalities.

Key hypotheses were that (1) the tax would be passed through to the prices of taxed beverages among the chain stores in which Berkeley implemented the tax in 2015; (2) sales of taxed beverages would decline, and sales of untaxed beverages would rise, in Berkeley stores more than in comparison non-Berkeley stores; (3) consumer spending per transaction (checkout episode) would not increase in Berkeley stores; and (4) self-reported consumption of taxed beverages would decline. Main outcomes and measures included changes in inflation-adjusted prices (cents/ounce), beverage sales (ounces), consumers’ spending measured as store revenue (inflation-adjusted dollars per transaction) in two large chains, and usual beverage intake (grams/day and kilocalories/day). Tax pass-through (changes in the price after imposition of the tax) for SSBs varied in degree and timing by store type and beverage type. Pass-through was complete in large chain supermarkets (+1.07¢/oz, p = 0.001) and small chain supermarkets and chain gas stations (1.31¢/oz, p = 0.004), partial in pharmacies (+0.45¢/oz, p = 0.03), and

    Successful colonoscopies require good bowel preparations-poor bowel preparations can increase medical costs, rates of missed lesions, and procedure duration. The combination of polyethylene glycol (PEG) 3350 without electrolytes (MiraLAX; Schering-Plough Healthcare Products, Inc, Kenilworth, NJ) and 64 oz of Gatorade (PepsiCo, Inc, Purchase, NY) has gained popularity as a bowel preparation regimen. However, the efficacy and tolerability of this approach has not been compared with standard bowel preparations in clinical trials. We compared split-dose (PEG) 3350 with electrolytes (GoLytely; Braintree Laboratories, Inc, Braintree, MA) with split-dose MiraLAX alone and in combination with pretreatment medications (bisacodyl or lubiprostone) to determine the efficacy and patient tolerability of MiraLAX as an agent for bowel preparation. We performed a prospective, randomized, blinded, controlled trial at a tertiary care center. Patients (n=403) were randomly assigned to groups given GoLytely, MiraLAX, MiraLAX with bisacodyl (10 mg), or MiraLAX with lubiprostone (24 μg). MiraLAX was combined with 64 oz of Gatorade. All patients were surveyed regarding preparation satisfaction and tolerability. The Ottawa bowel preparation scale was used to grade colon cleanliness. GoLytely was more effective at bowel cleansing (average Ottawa score, 5.1) than MiraLAX alone (average Ottawa score, 6.9) or in combination with lubiprostone (average Ottawa score, 6.8), or bisacodyl (average Ottawa score, 6.3) (P<.001). MiraLAX was associated with a trend toward longer procedure duration (P=.096). Groups given MiraLAX rated the overall experience as more satisfactory than those given GoLytely (P<.001). There were no differences between polyp detection rates (P=.346) or adverse events (P=.823). Split-dose MiraLAX in 64 oz of Gatorade is not as effective as 4 L split-dose GoLytely in bowel cleansing for screening colonoscopies. Copyright © 2011 AGA Institute. Published by Elsevier Inc. All

    Microwave, x-ray, and radio-frequency radiation sources require a cathode emitting electrons into vacuum. Thermionic B-type dispenser cathodes consist of BaxOz coatings on tungsten (W), where the surface coatings lower the W work function and enhance electron emission. The new and promising class of scandate cathodes modifies the B-type surface through inclusion of Sc, and their superior emissive properties are also believed to stem from the formation of a low work function surface alloy. In order to better understand these cathode systems, density-functional theory (DFT)-based ab initio modeling is used to explore the stability and work function of BaxScyOz on W(001) monolayer-type surface structures. It is demonstrated how surface depolarization effects can be calculated easily using ab initio calculations and fitted to an analytic depolarization equation. This approach enables the rapid extraction of the complete depolarization curve (work function versus coverage relation) from relatively few DFT calculations, useful for understanding and characterizing the emitting properties of novel cathode materials. It is generally believed that the B-type cathode has some concentration of Ba-O dimers on the W surface, although their structure is not known. Calculations suggest that tilted Ba-O dimers are the stable dimer surface configuration and can explain the observed work function reduction corresponding to various dimer coverages. Tilted Ba-O dimers represent a new surface coating structure not previously proposed for the activated B-type cathode. The thermodynamically stable phase of Ba and O on the W surface was identified to be the Ba0.25O configuration, possessing a significantly lower Φ value than any of the Ba-O dimer configurations investigated. The identification of a more stable Ba0.25O phase implies that if Ba-O dimers cover the surface of emitting B-type cathodes, then a nonequilibrium steady state must dominate the emitting surface. The identification of

    Current U.S. dietary guidance includes recommendations to increase intakes of both dietary fiber and whole grain (WG). This study examines fiber and WG intakes, food sources and trends from 2001 to 2010 based on National Health and Nutrition Examination Survey (NHANES) data for children/adolescents (n = 14,973) and adults (n = 24,809). Mean fiber intake for children/adolescents was 13.2 (±0.1) g/day. Mean fiber intake for adults 19–50 years (y) was 16.1 (±0.2) g/day and for adults 51+ was 16.1 (±0.2) g/day. There were significant increases in fiber intake from 2001–2010 for children/adolescents and for adults 51+ y. Mean WG intake for children/adolescents was 0.52 (±0.01) oz eq/day. Mean WG intake for adults 19–50 y was 0.61 (±0.02) oz eq/day and for adults 51+ 0.86 (±0.02) oz eq/day. There were no significant changes in WG intake for any age group from 2001–2010. The main food groups contributing to dietary fiber intake for children/adolescents were vegetables (16.6%), grain mixtures (16.3%), other foods (15.8%) and fruits (11.3%). For adults 19+ y, the main sources of dietary fiber were vegetables (22.6%), other foods (14.3%), grain mixtures (12.0%) and fruits (11.1%). Major WG sources for children/adolescents included ready-to-eat cereals (RTEC) (31%), yeast breads/rolls (21%) and crackers and salty grain snacks (21%). The main sources of WG for adults 19+ were yeast breads/rolls (27%), RTEC (23%) and pastas/cooked cereals/rice (21%). Recommending cereals, breads and grain mixtures with higher contents of both dietary fiber and WG, along with consumer education, could increase intakes among the United States (U.S.) population.

    Full Text Available A finales de 1823, la Sala de Representantes de San Miguel de Tucumán, dispuso la aprobación del decreto de pena de muerte para el gobernador Bernabé Aráoz, exiliado en la vecina ciudad de Salta. El entonces presidente de la Sala, el Presbítero José Manuel Moure, acudió a la formación de una comisión de eclesiásticos integrada por Diego León Villafañe (Jesuita, Pedro Miguel Aráoz y José Agustín Molina, para que se expresaran sobre el tema. Es a partir de este caso particular que nos preguntamos a cerca de la discusión sobre la pena de muerte, tanto en ámbito laico como eclesiástico; y de que manera este acontecimiento nos revela algunos rasgos de la relación entre “lo político” y lo religioso después de la revolución. Nos interesa indagar sobre las herramientas teóricas y jurídicas con las que se contaba en la época, para promulgarse sobre la materia. Abordar la decisión de la aplicación de la pena de muerte –en este caso a Bernabé Aráoz- desde un aspecto político jurídico eclesiástico, partiendo del hecho de que es una comisión eclesiástica la que finalmente avala la decisión. El clero fue uno de los actores fundamentales dentro del entramado social colonial. Este rol principal sufrió algunas modificaciones a partir de mayo de 1810, cuando la revolución empezó a delinear una nueva forma de relación entre la Iglesia y los individuos que la componían, y los nuevos poderes emergentes. La revolución y los nuevos gobiernos comenzaron a apropiarse de espacios específicos del clero, como el púlpito, al tiempo que éstos participaban de espacios políticos cada vez más “públicos”.

    Full Text Available RESUMO Os agrotóxicos, quando utilizados no meio ambiente, sofrem transformações bióticas e abióticas, gerando subprodutos com toxicidade maior ou semelhante ao agrotóxico de origem. No presente estudo foi investigada a dinâmica da presença de atrazina e seus produtos de degradação clorados, desisopropilatrazina e desetilhidroxiatrazina, na oxidação com ozônio, na filtração lenta em areia e na associação dos dois processos em instalação piloto. Foram estudadas as doses de ozônio de 0,9, 1,6 e 2,8 mg.L-1 para concentração de atrazina no afluente, variando de 30 a 79 µg.L-1. Para dose de ozônio de 2,8 mg.L-1, a concentração de atrazina foi inferior a 2 µg.L-1; no entanto, ocorreu formação de subprodutos em concentração superior a 3 µg.L-1. Na filtração lenta, não ocorreu redução da concentração de atrazina. Quando precedida da ozonização, para dose de 1,6 mg.L-1, a concentração de atrazina foi inferior a 2 µg.L-1 e atendeu ao valor máximo permitido pela Portaria MS 2.914/2011; entretanto, a concentração de subprodutos foi superior a 18 µg.L-1. Para dose de 2,8 mg.L-1, o valor de atrasina no efluente filtrado foi inferior a 0,1 µg.L-1, porém a somatória dos subprodutos clorados foi igual a 3,7 µg.L-1, ocorrendo comprometimento sanitário do efluente filtrado. A avaliação da remoção da atrazina em processos que utilizam a ozonização deve sempre estar associada ao monitoramento dos subprodutos clorados, principalmente o desetilatrazina, considerando que ocorre formação desses em concentração superior à da atrazina, produzindo água para abastecimento com elevado risco sanitário, e esses não constam da Portaria MS 2.914/2011.

  18. Generation and reactivity of putative support systems, Ce-Al neutral binary oxide nanoclusters: CO oxidation and C-H bond activation

    Both ceria (CeO2) and alumina (Al2O3) are very important catalyst support materials. Neutral binary oxide nanoclusters (NBONCs), CexAlyOz, are generated and detected in the gas phase and their reactivity with carbon monoxide (CO) and butane (C4H10) is studied. The very active species CeAlO4• can react with CO and butane via O atom transfer (OAT) and H atom transfer (HAT), respectively. Other CexAlyOz NBONCs do not show reactivities toward CO and C4H10. The structures, as well as the reactivities, of CexAlyOz NBONCs are studied theoretically employing density functional theory (DFT) calculations. The ground state CeAlO4• NBONC possesses a kite-shaped structure with an OtCeObObAlOt configuration (Ot, terminal oxygen; Ob, bridging oxygen). An unpaired electron is localized on the Ot atom of the AlOt moiety rather than the CeOt moiety: this Ot centered radical moiety plays a very important role for the reactivity of the CeAlO4• NBONC. The reactivities of Ce2O4, CeAlO4•, and Al2O4 toward CO are compared, emphasizing the importance of a spin-localized terminal oxygen for these reactions. Intramolecular charge distributions do not appear to play a role in the reactivities of these neutral clusters, but could be important for charged isoelectronic BONCs. DFT studies show that the reaction of CeAlO4• with C4H10 to form the CeAlO4H•C4H9• encounter complex is barrierless. While HAT processes have been previously characterized for cationic and anionic oxide clusters, the reported study is the first observation of a HAT process supported by a ground state neutral oxide cluster. Mechanisms for catalytic oxidation of CO over surfaces of AlxOy/MmOn or MmOn/AlxOy materials are proposed consistent with the presented experimental and theoretical results.

  19. Geochemical reversals within the lower 100 m of the Palisades sill, New Jersey

    Transects through the lower part of the Palisades sill were made at Fort Lee and Alpine, New Jersey in order to characterize the petrologic signature of previously proposed “reversals” in the normal, tholeiitic differentiation trend. Petrographic and geochemical data include: (1) modal and grain size analyses, (2) bulk rock major and trace element concentrations by DCP-AES, and (3) augite, orthopyroxene, magnetite, and olivine compositions by electron microprobe analysis. Anomalous horizons, defined by increased bulk rock Mg?, Cr, Ni, and Co concentrations and abrupt modal and grain-size changes, occur at 10 m (the well known olivine zone), 27 m, 45 m, and 95 m above the basal contact. Thermal models coupled with estimates of the emplacement rate and total magma volume indicate that the olivine zone (OZ) is an early-stage feature, related to the emplacement of initial magma into the Palisades chamber. Stoke’s Law calculations indicate that the settling velocity of average-sized olivine crystals in a high-titanium, quartz-normative (HTQ) magma is too slow for significant gravity settling to have occurred prior to the solidification of the basal 20 m of the sill. It is suggested that the OZ resulted from the emplacement of a heterogeneous initial magma from a compositionally stratified, sub-Palisades storage chamber located within the upper crust; however, heterogeneity may have been derived directly from the mantle or during rapid ascent. Geochemical models indicate that the OZ contains accumulated olivine that is not in cotectic (or constant) proportions with the other cumulus phases, suggesting a mechanical sorting process. Magma chamber recharge is proposed to have occurred at the 27 m and 45 m levels, when a slightly more-primitive HTQ magma was injected into the Palisades sill cha- mber. Zones of elevated Mg? and Cr, 6 to 10 m thick, at these two horizons may indicate the thickness of the hybrid magma formed by the mixing of these two compositions

    Two isolates of aerobic methanotrophic bacteria, strains Sph1T and Sph2, were obtained from cold methane seeps in a floodplain of the river Mukhrinskaya, Irtysh basin, West Siberia. Another morphologically and phenotypically similar methanotroph, strain OZ2, was isolated from a sediment of a subarctic freshwater lake, Archangelsk region, northern Russia. Cells of these three strains were Gram-stain-negative, light-pink-pigmented, non-motile, encapsulated, large cocci that contained an intracytoplasmic membrane system typical of type I methanotrophs. They possessed a particulate methane monooxygenase enzyme and utilized only methane and methanol. Strains Sph1T, Sph2 and OZ2 were able to grow at a pH range of 4.0-8.9 (optimum at pH 6.0-7.0) and at temperatures between 2 and 36 °C. Although their temperature optimum was at 20-25 °C, these methanotrophs grew well at lower temperatures, down to 4 °C. The major cellular fatty acids were C16 : 1ω5c, C16 : 1ω6c, C16 : 1ω7c, C16 : 1ω8c, C16 : 0 and C14 : 0; the DNA G+C content was 51.4-51.9 mol%. Strains Sph1T, Sph2 and OZ2 displayed nearly identical (99.1-99.7 % similarity) 16S rRNA gene sequences and belonged to the family Methylococcaceae of the class Gammaproteobacteria. The most closely related organism was Methylovulum miyakonense HT12T (96.0-96.5 % 16S rRNA gene sequence similarity and 90 % pmoA sequence similarity). The novel isolates, however, differed from Methylovulum miyakonense HT12T by cell morphology, pigmentation, absence of soluble methane monooxygenase, more active growth at low temperatures, growth over a broader pH range and higher DNA G+C content. On the basis of these differences, we propose a novel species, Methylovulum psychrotolerans sp. nov., to accommodate these methanotrophs. Strain Sph1T (=LMG 29227T=VKM B-3018T) is the type strain.

    Model Model complexity resulting from the need to integrate environmental system components cannot be understated. In particular, additional emphasis is urgently needed on rational approaches to guide decision making through uncertainties surrounding the integrated system across decision-relevant scales. However, in spite of the difficulties that the consideration of modeling uncertainty represent for the decision process, it should not be avoided or the value and science behind the models will be undermined. These two issues; i.e., the need for coupled models that can answer the pertinent questions and the need for models that do so with sufficient certainty, are the key indicators of a model's relevance. Model relevance is inextricably linked with model complexity. Although model complexity has advanced greatly in recent years there has been little work to rigorously characterize the threshold of relevance in integrated and complex models. Formally assessing the relevance of the model in the face of increasing complexity would be valuable because there is growing unease among developers and users of complex models about the cumulative effects of various sources of uncertainty on model outputs. In particular, this issue has prompted doubt over whether the considerable effort going into further elaborating complex models will in fact yield the expected payback. New approaches have been proposed recently to evaluate the uncertainty-complexity-relevance modeling trilemma (Muller, Muñoz-Carpena and Kiker, 2011) by incorporating state-of-the-art global sensitivity and uncertainty analysis (GSA/UA) in every step of the model development so as to quantify not only the uncertainty introduced by the addition of new environmental components, but the effect that these new components have over existing components (interactions, non-linear responses). Outputs from the analysis can also be used to quantify system resilience (stability, alternative states, thresholds or tipping

    Biomineralization processes have been applied in situ to protect and consolidate decayed ornamental stone of the Royal Chapel in Granada (Spain). In few years, this conservation treatment has gained worth attention as environmentally friendly methodology for protection and consolidation of limestone because of the compatibilities shown between the new calcium carbonate cement and the original stone substrate. Moreover, the success of this approach may be related to the diversity of the microbiota inhabiting the stone and activated upon the biotreatment application and throughout the time. González-Muñoz et al. (2008) proposed a nutritional solution that activate among the bacteria inhabiting the stone those with carbonatogenic activity. In this study, a long-term (one, two and three years) monitoring of the microbiota present on the treated and untreated stones was done using a molecular strategy, including total DNA extraction, PCR amplification of 16S rRNA sequences, construction of clone libraries and fingerprinting by DGGE (Denaturing Gradient Gel Electrophoresis) analysis. Sequencing of the 16S rDNA revealed the dominant occurrence of members of Actinobacteria (44.20%), Gamma-proteobacteria (30.24%) and Chloroflexi (25.56%) after one year of the biotreatment. Whereas after two years, members of Cyanobacteria (22.10%) appeared and three years after, the microbiota consisted of only Actinobacteria and Cyanobacteria with approximately the same percentage in comparison with the untreated stones, dominated exclusively by Actinobacteria (100%). Fungal diversity followed the same dynamic as bacterial diversity being Ascomicota the predominant order before treatment. After one year, members of Basidiomycota and Viridiplantae appeared on the stone while two years after, the Viridiplantae dominated with a percentage of 84.77%. Finally, three years after the treatment, fungi population started to stabilize again and Ascomicota predominated next to 16.67% of

    Added sugar intake, in the form of sugar-sweetened beverages (SSBs), may contribute to weight gain and obesity development in children and adolescents. A valid and reliable brief beverage intake assessment tool for children and adolescents could facilitate research in this area. The purpose of this investigation was to evaluate the relative validity and test-retest reliability of a 15-item beverage intake questionnaire (BEVQ) for assessing usual beverage intake in children and adolescents. This cross-sectional investigation included four study visits within a 2- to 3-week time period. Participants (333 enrolled; 98% completion rate) were children aged 6 to 11 years and adolescents aged 12 to18 years recruited from the New River Valley, VA, region from January 2014 to September 2015. Study visits included assessment of height/weight, health history, and four 24-hour dietary recalls (24HRs). The BEVQ was completed at two visits (BEVQ 1, BEVQ 2). To evaluate relative validity, BEVQ 1 was compared with habitual beverage intake determined by the averaged 24HR. To evaluate test-retest reliability, BEVQ 1 was compared with BEVQ 2. Analyses included descriptive statistics, independent sample t tests, χ 2 tests, one-way analysis of variance, paired sample t tests, and correlational analyses. In the full sample, self-reported water and total SSB intake were not different between BEVQ 1 and 24HR (mean differences 0±1 fl oz and 0±1 fl oz, respectively; both P values >0.05). Reported intake across all beverage categories was significantly correlated between BEVQ 1 and BEVQ 2 (Pbeverages was not different (all P values >0.05) between BEVQ 1 and 24HR (mean differences: whole milk=3±4 kcal, reduced-fat milk=9±5 kcal, and fat-free milk=7±6 kcal, which is 7±15 total beverage kilocalories). In adolescents (n=200), water and SSB kilocalories were not different (both P values >0.05) between BEVQ 1 and 24HR (mean differences: -1±1 fl oz and 12±9 kcal, respectively). A 15

    To evaluate the gastric emptying time of pharmaceutical dosage forms in a clinical setting, a relatively simple dual-radionuclide technique was developed. Placebo tablets of six different combinations of shape and size were labeled with indium-111 DTPA and enteric coated. Six volunteers participated in a single-blind and crossover study. Tablets were given in the morning of a fasting stomach with 6 oz of water containing /sup 99m/Tc pertechnetate and continuously observed with a gamma camera. A scintigraph was obtained each minute. The results suggested that the size, shape, or volume of the tablet used in this study had no significant effect in the rate of gastric emptying. The tablets emptied erratically and unpredictably, depending upon their time of arrival in the stomach in relation to the occurrence of interdigestive myoelectric contractions. The method described is a relatively simple and accurate technique to allow one to follow the gastric emptying of tablets

    Full Text Available Computer-supported learning is an increasingly important form of study since it allows for independent learning and individualized instruction. In this paper, we discuss a novel approach to developing an intelligent tutoring system for teaching textbook-style mathematical proofs. We characterize the particularities of the domain and discuss common ITS design models. Our approach is motivated by phenomena found in a corpus of tutorial dialogs that were collected in a Wizard-of-Oz experiment. We show how an intelligent tutor for textbook-style mathematical proofs can be built on top of an adapted assertion-level proof assistant by reusing representations and proof search strategies originally developed for automated and interactive theorem proving. The resulting prototype was successfully evaluated on a corpus of tutorial dialogs and yields good results.

    Bryson, E.

    Ever since my introduction to the World Wide Web (WWW), it's been love at first byte. Searching on the WWW is similar to being able to go to a public library and allow yourself to be transported to any other book or library around the world by looking at a reference or index and clicking your heels together like Dorothy did in "The Wizard of Oz", only the clicking is done with a computer mouse. During this presentation, we will explore the WWW protocols which allow clients and servers to communicate on the Internet. We will demonstrate the ease with which users can navigate the virtual tidal wave of information available with a mere click of a button. In addition, the workshop will discuss the revolutionary aspects of this network information system and how it's impacting our libraries as a primary mechanism for rapid dissemination of knowledge.

    OBJECTIVE To test the hypothesis that greater chocolate-candy intake is associated with more weight gain in postmenopausal women. DESIGN AND METHODS Prospective cohort study involving 107,243 post-menopausal American women aged 50–79 years (mean=60.7) at enrolment in the Women’s Health Initiative (WHI), with three-year follow up. Chocolate-candy consumption was assessed by food frequency questionnaire and body weight was measured. Linear mixed models, adjusted for demographic, socio-economic, anthropomorphic and behavioral variables, were used to test our main hypotheses. RESULTS Compared to women who ate a 1 oz (~28 g) serving of chocolate candy chocolate-candy intake level increased as BMI increased above the normal range (18.5–25 kg/m2), and as age decreased. CONCLUSIONS Greater chocolate-candy intake was associated with greater prospective weight gain in this cohort of post-menopausal women. PMID:25644711

    Full Text Available This paper conducts the research on the attention sates based on ERP analysis when the subjects are under the quiet, flute and zither background music. The amplitude and latency of P300 are analyzed. The results show that there are greater P300 amplitudes and smaller P300 latencies of CZ, PZ, OZ and CP3 in music background than those in quiet background. The PCA and ICA achieve to select the effective data components and the head model is reconstructed. The active degree of brain areas are analyzed by using the source location methods. The result shows that the brain’s excitement is very obvious under the Bach's flute background. The study also indicates that some background music might help to improve the attention.

    1984-02-01

    Oral sodium bicarbonate is used to treat metabolic acidosis in patients with renal tubular acidosis. Since infants and young children are unable to swallow tablets, those affected must ingest sodium bicarbonate in a powder or liquid form. Pharmacy-weighed sodium bicarbonate is expensive and inconvenient to obtain; some pharmacists are reluctant to provide it. We determined that the sodium bicarbonate contained in 8-oz boxes of Arm and Hammer Baking Soda was sufficiently constant in weight that, dissolved in water to a given volume, it yielded a quantitatively acceptable therapeutic solution of sodium bicarbonate at a cost of approximately 3 percent of that of pharmacy-weighed sodium bicarbonate. Grocery store baking soda can be a safe, economical, and convenient source of sodium bicarbonate for the treatment of chronic metabolic acidosis in infants and young children.

  20. Absence of a Scott correction for the total binding energy of noninteracting fermions in a smooth potential well

    Huxtable, B.D.

    1988-01-01

    It is shown, for V in a particular class of smooth functions, that the total binding energy, E(Z), of Z noninteracting Fermions in the potential well Z 4/3 V(Z 1/3 X) obeys E(Z) = c TF (V)Z 7/3 + O(Z 5/3 ) as Z → ∞. Here c TF (V) is the coefficient predicted by Thomas-Fermi theory. This result is consistent with the conjectured Scott correction, which occurs at order Z 2 , to the total binding energy of an atomic number Z. This correction is thought to arise only because V(x)∼ - |x| -1 near x = 0 in the atomic problem, and so V is not a smooth function

    2018-05-01

    In a recent paper (Muñoz and Soto-Garrido 2017 J. Phys.: Condens. Matter 29 445302) we have studied the effects of mechanical strain and magnetic field on the electronic transport properties in graphene. In this article we extended our work to Weyl semimetals (WSM). We show that although the WSM are 3D materials, most of the analysis done for graphene (2D material) can be carried out. In particular, we studied the electronic transport through a cylindrical region submitted to torsional strain and external magnetic field. We provide exact analytical expressions for the scattering cross section and the transmitted electronic current. In addition, we show the node-polarization effect on the current and propose a recipe to measure the torsion angle from transmission experiments.

    1992-01-01

    The results of the theoretical analysis of anomalous (collisionless) radio wave absorption in the turbulent auroral ionosphere during the intrusion of energetic electrons (i.e., in aurorae) are presented. The implications of the plasma turbulent layer (PTL) theory are used. It is shown that the dissipation of radio waves with frequencies much higher than the plasma frequency is caused by the nonlinear (combined) scattering in turbulent plasma of the PTL. In the auroral electrojet layer the principal dissipative process for the radio waves with frequencies close to the plasma frequency is O-Z transformation on the field-aligned, small-scale density fluctuations. The typical dissipation decrements are estimated. 26 refs

    2010-11-19

    Metal gate work function enhancement using nanoscale (1.0 nm) Gd2O3 interfacial layers has been evaluated as a function of silicon oxide content in the HfxSiyOz gate dielectric and process thermal budget. It is found that the effective work function tuning by the Gd2O3 capping layer varied by nearly 400 mV as the composition of the underlying dielectric changed from 0% to 100% SiO2, and by nearly 300 mV as the maximum process temperature increased from ambient to 1000 °C. A qualitative model is proposed to explain these results, expanding the existing models for the lanthanide capping layer effect.

    The pET symptoms are tended to be masked in the recumbent position. CT for pET should be examined in the sitting position. CT was performed under the resting and Valsalva's condition. Completely open ET was observed in 79.2% of the pET group (n=111), but in none of the control group (n=30). The average ET-gram showed an occlusive zone (OZ) in medial to the isthmus under both conditions in only control group. Trans-tympanic silicone plug insertion was thought to be reasonable technique because of obliteration approach to isthmus. Office-based CT examined in the sitting position is useful for diagnosis and evaluation of pET. (author)

    What are you thinking about? There is a crisis in recruiting physics teachers throughout Northern Europe. Detailed research has shown that the problem may be one of image. It seems that being a teacher is seen as something slightly strange. So is being a physicist. This makes anyone who is a physics teacher (strange)2. This effect becomes overwhelming when more than one physics teacher is present, making attendance at gatherings of physics teachers almost unthinkable for the average person. So just what is it that sets physicists aside from the rest of the population? Why do they think we are so strange? Clearly it is how we think about things. We enter a room and estimate its volume. We visit the fairground and we wonder about the g force. At a football match we estimate the size of the crowd. At sunset we see scattering and at the beach, as the sun glints off the clear water, we think about Brewster's angle, and we estimate the number of pebbles on the beach. We find potential visits and lesson-material at hospitals, concerts, restaurants and on every possible mode of transport. Thinking about things like that is what makes us physics teachers. Surely everyone has seen The Wizard of Oz. I want you to imagine that you are watching it along with some friends who are not physics teachers. Let's see what they are all thinking about. One is a Roads Engineer. What a state the yellow brick road is in! As the major route in the country of Oz it obviously needs an upgrade. A nice black tarmac surface, some road markings and lighting at the major intersections. There is something else wrong. Dorothy, the Tin man, Scarecrow and Lion are just walking along. Where are the road works, traffic jams and hold-ups? Another friend is a school principal. What an amazing leadership style the Wizard has. Perhaps it would work at school? Those munchkins run around a bit though. There would be a need for some rules about how to play in the playground. Perhaps if the mayor of the

    Full Text Available Total or partial sleep deprivation (SD causes degrading effects on different cognitive and psychomotor functions that might be related to electrophysiological changes frequently observed. In the present study, we investigated the effects of one night of sleep deprivation on waking EEG. Experimental protocol consisted of recording electroencephalographic data from eleven healthy young subjects before (baseline and after (time 2 one night of sleep deprivation.

    Preclinical studies demonstrate that apple juice exerts multiple beneficial effects including reduction of central nervous system oxidative damage, suppression of Alzheimer's disease (AD) hallmarks, improved cognitive performance, and organized synaptic signaling. Herein, we initiated an open-label clinical trial in which 21 institutionalized individuals with moderate-to-severe AD consumed 2 4-oz glasses of apple juice daily for 1 month. Participants demonstrated no change in the Dementia Rating Scale, and institutional caregivers reported no change in Alzheimer's Disease Cooperative Study (ADCS)-Activities of Daily Living (ADL) in this brief study. However, caregivers reported an approximate 27% (P Inventory, with the largest changes in anxiety, agitation, and delusion. This pilot study suggests that apple juice may be a useful supplement, perhaps to augment pharmacological approaches, for attenuating the decline in mood that accompanies progression of AD, which may also reduce caregiver burden.

  2. Small Angle Neutron Scattering Studies of the Counterion Effects on the Molecular Conformation and Structure of Charged G4 PAMAM Dendrimers in Aqueous Solutions

    2007-01-01

    The structural properties of generation 4 (G4) poly(amidoamine) starburst dendrimers (PAMAM) with an ethylenediamine ne (EDA) central core in D O 2 solutions have been studied by small angle neutron scattering. Upon the addition of DCl , SANS patterns show a pronounced inter-particle 2 correlation peaks due to the strong repulsion introduced by the protonation of the amino groups of the dendrimers. By solving the Ornstein-Zernike integral equation (OZ) with hypernetted chain closure (HNC), the dendrimer-dendrimer er structure factor S(Q) is determined and used to fit the experimental data. Quantitative information such as the effective charge per dendrimer and its conformational change at different conditions can be obtained. The results obtained show clear evidence that significant counterion association occurs, strongly mediating the inter-dendrimer interaction. The influence of interplay between counterions and molecular protonation of dendrimers has strong effect on the dendrimer conformation and effective interaction.

It was a highly successful event owing to the number of participants, the quality of the speakers, and the academic programme. Around 48 professors from 8 different countries came and shared their knowledge and experience of cancer management. They also talked about the most recent developments noted or achieved in this area. The keynote speech from Dr Nubia Muñoz was of great interest which was related to the safety of a HPV vaccine and the implications of a mass vaccination programme in developing countries. Geriatric oncology and palliative care were also topics that sparked great interest during the event.

    Avatars are a common field of research for interfacing smart homes, especially for elderly people. The present study focuses on the usage of photo-realistic faces with different levels of movements (video, avatar and photo) as components of the graphical user interface (GUI) for Ambient Assisted Living (AAL) environments. Within a usability test, using the "Wizard of Oz" technique, these presentation modes were compared with a text and a voice only interface with users of the target groups: elderly people with (nMCI=12) and without (nMCI=12) Mild Cognitive Impairment (MCI). Results show that faces on the GUI were liked by both, elderly with and without cognitive restrictions. However, users' performance on executing tasks did not differ much between the different presentation modes.

    2010-01-01

    Metal gate work function enhancement using nanoscale (1.0 nm) Gd2O3 interfacial layers has been evaluated as a function of silicon oxide content in the HfxSiyOz gate dielectric and process thermal budget. It is found that the effective work function tuning by the Gd2O3 capping layer varied by nearly 400 mV as the composition of the underlying dielectric changed from 0% to 100% SiO2, and by nearly 300 mV as the maximum process temperature increased from ambient to 1000 °C. A qualitative model is proposed to explain these results, expanding the existing models for the lanthanide capping layer effect.

    The main reactions considered in OM mineralization during early diagenesis of sediment are listed in Table 1. Under oxidant-depleted conditions, fermentation of metabolizable OM of general formula CxHyOz can yield acetate, CO2 and H2 (r1). Note that reaction r1 takes into account any source of CO2 during fermentation including the partial degradation of high molecular weight OM (HMW OM) into lower molecular weight OM (LMW OM; Corbett et al., 2013; Corbett et al., 2015). The products of this reaction yield CH4 via either acetate fermentation (r2) or hydrogenotrophy (r3). In addition, when electron acceptors (EAs), i.e., Fe(III), SO42-, and partially oxidized HS, are present, CH4 (r4) and OM (r5) can be oxidized to produce CO2. Here, nitrate and Mn oxyhydroxides were not considered as oxidants, owing to the very low concentration of the former (values (SI ≥ 0.5).

    In the previous study, during the vertex sharp wave period (hypnagogic EEG stage 4), negative components (N300, N550) were dominant at Fz and Cz in contrast to the positive component (P400) being prominent at the other areas, Pz, Oz, T5 and T6. There is no agreement regarding P400 properties during the hypnagogic period. In this study, using topographic mapping, we found that two negative components (N300, N550) and P400 independently increased their amplitude at the different areas of the scalp as arousal level lowered. The anterior negative components may reflect the information processing related to the K-complex. The P400 may reflect other activities different from the K-complex mechanism or P300 attention mechanisms.

    Persuasive conversational agents persuade people to change their attitudes or behaviors through conversation, and are expected to be applied as virtual sales clerks in e-shopping sites. As an approach to create such an agent, we have developed a learning agent with the Wizard of Oz method in which a person called Wizard talks to the user pretending to be the agent. The agent observes the conversations between the Wizard and the user, and learns how to persuade people. In this method, the Wizard has to reply to most of the user's inputs at the beginning, but the burden gradually falls because the agent learns how to reply as the conversation model grows.

    High-silica rhyolite magma fuels Earth's largest and most explosive eruptions. Recurrence intervals for such highly explosive eruptions are in the 100- to 100,000­year time range, and there have been few direct observations of such eruptions and their immediate impacts. Consequently, there was keen interest within the volcanology community when the first large eruption of high-silica rhyolite since that of Alaska's Novarupta volcano in 1912 began on 1 May 2008 at Chaitén volcano, southern Chile, a 3-kilometer­diameter caldera volcano with a prehistoric record of rhyolite eruptions [Naranjo and Stern, 2004; Servicio Nacional de Geología y Minería (SERNAGEOMIN), 2008; Carn et al., 2009; Castro and Dingwell, 2009; Lara, 2009; Muñoz et al., 2009]. Vigorous explosions occurred through 8 May 2008, after which explosive activity waned and a new lava dome was extruded.

    Whole grain (WG) foods have been shown to reduce chronic disease risk and overweight. Total dietary fiber is associated with WG and its health benefits. The purpose was to determine whether associations exist between WG intake (no-WG intake, 0 ounce equivalent [oz eq]; low, >0-cereals and yeast breads/rolls in the high WG intake group compared with the no-WG intake group. Major WG sources for children/adolescents and adults included yeast bread/rolls (24% and 27%, respectively), RTE cereals (25% and 20%, respectively), and oatmeal (12% and 21%, respectively). Among those with the highest WG intake, WG RTE cereal with no added bran was the greatest contributor to total dietary fiber compared with other RTE cereal types. Whole grain foods make a substantial contribution to total dietary fiber intake and should be promoted to meet recommendations. Copyright © 2014 The Authors. Published by Elsevier Inc.

  4. The limitations of seedling growth and drought tolerance to novel soil substrates in arid systems: Implications for restoration success

    2016-04-01

    Introduction With the limited knowledge available regarding the impact of drought on seedling growth, an understanding of seedling tolerance to arid conditions is crucial for restoration success (James et al., 2013; Muñoz-Rojas et al., 2014). However, restoration in semi-arid areas faces the challenge of re-establishing plant communities on altered soil substrates (Muñoz-Rojas et al., 2015). These substrates are a result of anthropogenic disturbances such as mining which have altered the plant-soil-water dynamics of the ecosystem (Machado et al., 2013). The aim of this study was to assess the impact of mining on the plant-soil-water dynamics of an arid ecosystem of Western Australia (Pilbara region, North Western Australia) and the implications these altered relationships have on seedling growth and their responses to drought. Methods Drought responses of native plant species were assessed through a series of glasshouse experiments. Firstly, 21 species dominant to the Pilbara region were subjected to drought in a topsoil growth media to assess variation in responses (leaf water potential at the time of stomatal closure) across species and identify traits associated with drought tolerance. Secondly, four species ranging in their drought tolerance identified previously, were grown to two leaf stages (second and fourth leaf stage) in three mining substrates (topsoil, a topsoil and waste mix and waste) to assess seedling drought responses to various potential restoration substrates and how that varied with plant development stage. Results and discussion Four morphological traits were found to be significantly associated with drought indicators (leaf mass ratio, stem area, stem length, stem weight), however, these were weak correlations. Waste substrate and its addition to topsoil reduced plant total biomass but did not alter species responses to drought. However, the soil physical properties of the waste reduced water retention and water availability for plant uptake

    More than 420 million oz of gold were concentrated in circum-Pacific synorogenic quartz loades mainly during two periods of continental growth, one along the Gondwanan margin in the Palaeozoic and the other in the northern Pacific basin between 170 and 50 Ma. These ores have many features in common and can be grouped into a single type of lode gold deposit widespread throughout clastic sedimentary-rock dominant terranes. The auriferous veins contain only a few percent sulphide minerals, have gold:silver ratios typically greater than 1:1, show a distinct association with medium grade metamorphic rocks, and may be associated with large-scale fault zone. Ore fluids are consistently of low salinity and are CO2-rich. In the early and middle Palaeozoic in the southern Pacific basin, a single immense turbidite sequence was added to the eastern margin of Gondwanaland. Deformation of these rocks in southeastern Australia was accompanied by deposition of at least 80 million oz of gold in the Victorian sector of the Lachlan fold belt mainly during the Middle and Late Devonian. Lesser Devonian gold accumulations characterized the more northerly parts of the Gondwanan margin within the Hodgkinson-Broken River and Thomson fold belts. Additional lodes were emplaced in this flyschoid sequence in Devonian or earlier Palaeozoic times in what is now the Buller Terrane, Westland, New Zealand. Minor post-Devonian growth of Gondwanaland included terrane collision and formation of gold-bearing veins in the Permian in Australia's New England fold belt and in the Jurassic-Early Cretaceous in New Zealand's Otago schists. Collision and accretion of dozens of terranes for a 100-m.y.-long period against the western margin of North America and eastern margin of Eurasia led to widespread, lattest Jurassic to Eocene gold veining in the northern Pacific basin. In the former location, Late Jurassic and Early Cretaceous veins and related placer deposits along the western margin of the Sierra Nevada

    Located in the Iberian Pyrite Belt (IPB) northern sector, near the Portuguese/Spanish border, the outcropping São Domingos deposit was mined since Roman time. Between 1854 and 1966 the Mason & Barry Company developed open pit excavation until 120 m depth and underground mining until 420 m depth. The São Domingos subvertical deposit is associated with felsic volcanics and black shales of the IPB Volcano-Sedimentary Complex and is represented by massive sulphide and stockwork ore (py, cpy, sph, ga, tt, aspy) and related supergene enrichment ore (hematite gossan and covellite/chalcocite). Different mine waste classes were mapped around the old open pit: gossan (W1), felsic volcanic and shales (W2), shales (W3) and mining waste landfill (W4). Using the LNEG (Portuguese Geological Survey) CONASA database (company historical mining waste characterization based on 162 shafts and 160 reverse circulation boreholes), a methodology for tridimensional modelling mining waste pile was followed, and a new mining waste resource is presented. Considering some constraints to waste removal, such as the Mina de São Domingos village proximity of the wastes, the industrial and archaeological patrimony (e.g., mining infrastructures, roman galleries), different resource scenarios were considered: unconditioned resources (total estimates) and conditioned resources (only the volumes without removal constraints considered). Using block modelling (SURPAC software) a mineral inferred resource of 2.38 Mt @ 0.77 g/t Au and 8.26 g/t Ag is estimated in unconditioned volumes of waste. Considering all evaluated wastes, including village areas, an inferred resource of 4.0 Mt @ 0.64 g/t Au and 7.30 g/t Ag is presented, corresponding to a total metal content of 82,878 oz t Au and 955,753 oz t Ag.

    Aluminum-containing antacids (e.g Amphojel) and aluminum-containing compounds such as sucralfate (Carafate) have been shown in animal and human studies to delay gastric emptying, and are one proposed mechanism of action for healing of duodenal ulcers. Therefore, the authors designed a study to study the effects of Carafate and Amphojel on gastric emptying. Ten normal volunteers of mean age 27 years with no previous history of upper gastrointestinal diseases were studied. For each test the subject ingested a meal composed of 30gm of cooked chicken liver injected with lmCi of 99m-Tc-S-C, mixed with 7.5 oz. of beef stew, and eaten with 4 oz. of water labeled with 100μCi of 111-In-DTPA. Immediately after ingestion of the meal, the subject was placed supine under a gamma camera. Gastric emptying (GE) was expressed as percent emptied. On separate days the subject was given either lgm of Carafate (190mg Al/gm) or placebo in a double blind fashion one hour prior to the test meal. On the third day, each subject was given 30cc of Amphojel (105mg Al/5cc) followed 30 minutes later by the test meal. GE at 2 hours for the solid meal was 60%, 69%, and 54% and 79%, 86% and 68% at 3 hours for placebo, Carafate, and Amphojel respectively. A small but not significant difference in gastric emptying between Amphojel and placebo was seen from 2 to 3 hours. For the liquid meal approximately 90% emptying was present at 1 hour for all three studies. Further studies are needed to determine whether these medications administered in the standard doses given here may affect gastric emptying in duodenal ulcer patients

    Australia has been a leader in global mineral exploration expenditure since 1993. It is a country with an outstanding exploration record, vast tracts of land, and minimal exploration with great datasets. It is also one of the world's most stable governments where projects are easily developed with world class technology and people. Although Australian exploration has been successful, trends must be carefully observed to see if the cycle may turn. The best success rate has been for gold. Between 1970 and 2000, 136 discoveries were made, including 7 significant deposits with greater than 12 m ozs reserves operating or under construction. There are 11 advanced projects with potential for more than 40 m ozs. Other successful exploration ventures in Australia have been in the mineral sands, nickel, base metals, copper and diamonds, each against difficult commodity prices. Australia is cost competitive with Africa, Asia, Latin America, Canada and the United States. It was noted that large areas of Australia still remain unexplored, with the Central Australian Proterozoic area holding more than 5,000,000 square km of prospective terrains. The paper highlighted the Lake Mackay Project, the Yilgarn Craton, exploration drilling in the Yandal region, and the mineral potential in the Westside and Barton areas. From 1995 to 2001, nine new gold mines have been successfully commissioned at a cost of half the world average. The advantages include an excellent infrastructure in camps, world class support in construction, and a favourable Australian dollar and tax regime. The paper also described major projects commissioned between 1996 and 2000 for base metals (lead, zinc, silver and copper), nickel, aluminium and magnesium. 15 figs.

    Full Text Available Abstract Background Metabolic Syndrome, or Syndrome X, is characterized by a set of metabolic and lipid imbalances that greatly increases the risk of developing diabetes and cardiovascular disease. The syndrome is highly prevalent in the United States and worldwide, and treatments are in high demand. ProAlgaZyme, a novel and proprietary freshwater algae infusion in purified water, has been the subject of several animal studies and has demonstrated low toxicity even with chronic administration at elevated doses. The infusion has been used historically for the treatment of several inflammatory and immune disorders in humans and is considered well-tolerated. Here, the infusion is evaluated for its effects on the cardiovascular risk factors present in metabolic syndrome in a randomized double-blind placebo-controlled study involving 60 overweight and obese persons, ages 25–60. All participants received four daily oral doses (1 fl oz of ProAlgaZyme (N = 22 or water placebo (N = 30 for a total of 10 weeks, and were encouraged to maintain their normal levels of physical activity. Blood sampling and anthropometric measurements were taken at the beginning of the study period and after 4, 8 and 10 weeks of treatment. Eight participants did not complete the study. Results ProAlgaZyme brought about statistically significant (p Conclusion ProAlgaZyme (4 fl oz daily consumption resulted in significant reductions in weight and blood glucose levels, while significantly improving serum lipid profiles and reducing markers of inflammation, thus improving cardiovascular risk factors in overweight and obese subjects over a course of 10 weeks with an absence of adverse side effects.

    Intakes of sodium, saturated fat, and trans fat remain high despite recommendations to limit these nutrients for cardiometabolic risk reduction. A major contributor to intake of these nutrients is foods prepared outside the home, particularly from fast-food restaurants. We analyzed the nutrient content of frequently ordered items from 3 US national fast-food chains: fried potatoes (large French fries), cheeseburgers (2-oz and 4-oz), and a grilled chicken sandwich. We used an archival website to obtain data on sodium, saturated fat, and trans fat content for these items from 2000 through 2013. The amount of each nutrient per 1,000 kcal was calculated to determine whether there were trends in product reformulation. Sodium content per 1,000 kcal differed widely among the 3 chains by food item, precluding generalizations across chains. During the 14-year period, sodium content per 1,000 kcal for large French fries remained high for all 3 chains, although the range narrowed from 316-2,000 mg per 1,000 kcal in 2000 to 700-1,420 mg per 1,000 kcal in 2013. Among the items assessed, cheeseburgers were the main contributor of saturated fat, and there was little change in content per 1,000 kcal for this item during the 14-year period. In contrast, there was a sharp decline in saturated and trans fat content of large French fries per 1,000 kcal. Post-2009, the major contributor of trans fat per 1,000 kcal was cheeseburgers; trans fat content of this item remained stable during the 14-year period. With the exception of French fries, little evidence was found during the 14-year period of product reformulation by restaurants to become more consistent with dietary guidance to reduce intakes of sodium and saturated fat.

  13. Disgust and Suppression of the Visual Cortex: Lateralization Effects?

    Full Text Available Research has shown that unlike other threat emotions, disgust does not evoke a typical sympathetic fight or flight response. Rather, disgust induces a parasympathetic response. A recent EEG study has demonstrated that this inhibitory reaction is also present in neuronal systems. Disgust stimuli elicited diminished Visual Event Related Potential (VERP amplitude in comparison to neutral and fear stimuli at P1 in the posterior Oz electrode (Kruesmark and Li, 2011 J Neurosci 31 (9, 3429–3434. In order to investigate whether VERPs were sensitive to different domains of disgust, we presented participants with random sequence of neutral, sociomoral, mutilation, and contamination images derived from the IAPS database. EEG results indicated no significant effect at Oz contrary to prior research. The results did, however, demonstrate lateralization effects. Whilst no differences were found between the disgust conditions themselves, the left P1 potential for all the disgust conditions was significantly attenuated compared to neutral. Conversely, this effect did not occur in the right posterior electrodes. In a second study, we presented the different disgust images in blocks in order to investigate the role of anticipation. Again, the left sided P1 was attenuated compared to neutral; however, on the right, mutilation elicited significantly greater P1 amplitude than did all other conditions. The results suggest suppressed visual processing for disgust elicitors in the left posterior regions and heightened activity for mutilation stimuli in the right, when mutilation was expected. These results may reflect a lateralized approach-avoidance mechanism, which begins as early as 125 ms after stimulus onset.

  14. Anticancer properties of distinct antimalarial drug classes.

    Rob Hooft van Huijsduijnen

    Full Text Available We have tested five distinct classes of established and experimental antimalarial drugs for their anticancer potential, using a panel of 91 human cancer lines. Three classes of drugs: artemisinins, synthetic peroxides and DHFR (dihydrofolate reductase inhibitors effected potent inhibition of proliferation with IC50s in the nM- low µM range, whereas a DHODH (dihydroorotate dehydrogenase and a putative kinase inhibitor displayed no activity. Furthermore, significant synergies were identified with erlotinib, imatinib, cisplatin, dasatinib and vincristine. Cluster analysis of the antimalarials based on their differential inhibition of the various cancer lines clearly segregated the synthetic peroxides OZ277 and OZ439 from the artemisinin cluster that included artesunate, dihydroartemisinin and artemisone, and from the DHFR inhibitors pyrimethamine and P218 (a parasite DHFR inhibitor, emphasizing their shared mode of action. In order to further understand the basis of the selectivity of these compounds against different cancers, microarray-based gene expression data for 85 of the used cell lines were generated. For each compound, distinct sets of genes were identified whose expression significantly correlated with compound sensitivity. Several of the antimalarials tested in this study have well-established and excellent safety profiles with a plasma exposure, when conservatively used in malaria, that is well above the IC50s that we identified in this study. Given their unique mode of action and potential for unique synergies with established anticancer drugs, our results provide a strong basis to further explore the potential application of these compounds in cancer in pre-clinical or and clinical settings.

    Full Text Available AIM:To determine risk factors of regression and undercorrection following photorefractive keratectomy (PRK in myopia or myopic astigmatism.METHODS: A case-control study was designed in which eyes with an indication for re-treatment (RT were defined as cases; primary criteria for RT indication, as assessed at least 9mo postoperatively, included an uncorrected distance visual acuity (UDVA of 20/30 or worse and a stable refraction for more than 3mo. Additional considerations included optical quality symptoms and significant higher order aberrations (HOAs. Controls were chosen from the same cohort of operated eyes which had complete post-operative follow up data beyond 9mo and did not need RT. The cohort included patients who had undergone PRK by the Tissue-Saving (TS ablation profile of Technolas 217z100 excimer laser (Bausch & Lomb, Rochester, NY, USA. Mitomycin C had been used in all of the primary procedures.RESULTS:We had 70 case eyes and 158 control eyes, and they were comparable in terms of age, sex and follow-up time (P values:0.58, 1.00 and 0.89, respectively. Pre-operative spherical equivalent of more than -5.00 diopter (D, intended optical zone (OZ diameter of less than 6.00 mm and ocular fixation instability during laser ablation were associated with RT indications (all P values <0.001. These factors maintained their significance in the multiple logistic regression model with odd ratios of 6.12, 6.71 and 7.89, respectively.CONCLUSION:Higher refractive correction (>-5.00 D, smaller OZ (<6.00 mm and unstable fixation during laser ablation of PRK for myopia and myopic astigmatism were found to be strong predictors of undercorrection and regression.

    Caffeine is the most widely consumed drug in the world with coffee representing a major source of intake. Despite widespread availability, various medical conditions necessitate caffeine-restricted diets. Patients on certain prescription medications are advised to discontinue caffeine intake. Such admonition has implications for certain psychiatric patients because of pharmacokinetic interactions between caffeine and certain anti-anxiety drugs. In an effort to abstain from caffeine, patients may substitute decaffeinated for caffeinated coffee. However, decaffeinated beverages are known to contain caffeine in varying amounts. The present study determined the caffeine content in a variety of decaffeinated coffee drinks. In phase 1 of the study, 10 decaffeinated samples were collected from different coffee establishments. In phase 2 of the study, Starbucks espresso decaffeinated (N=6) and Starbucks brewed decaffeinated coffee (N=6) samples were collected from the same outlet to evaluate variability of caffeine content of the same drink. The 10 decaffeinated coffee samples from different outlets contained caffeine in the range of 0-13.9 mg/16-oz serving. The caffeine content for the Starbucks espresso and the Starbucks brewed samples collected from the same outlet were 3.0-15.8 mg/shot and 12.0-13.4 mg/16-oz serving, respectively. Patients vulnerable to caffeine effects should be advised that caffeine may be present in coffees purported to be decaffeinated. Further research is warranted on the potential deleterious effects of consumption of "decaffeinated" coffee that contains caffeine on caffeine-restricted patients. Additionally, further exploration is merited for the possible physical dependence potential of low doses of caffeine such as those concentrations found in decaffeinated coffee.

    The short-term physical and chemical stability of an oral suspension of thalidomide 20 mg/mL was studied. An oral suspension of thalidomide 20 mg/mL was prepared by emptying the contents of 12 100-mg thalidomide capsules into a glass mortar; 30 mL of Ora-Plus and 30 mL of Ora-Sweet were mixed and added to the thalidomide powder to make a final volume of 60 mL. Three identical samples of the formulation were prepared and placed in 2-oz amber plastic bottles with child-resistant caps and stored under refrigeration (3-5 °C). A 1-mL sample was withdrawn from each of the three samples with a micropipette immediately after preparation and at 7, 14, 21, 28, and 35 days. After further dilution to an expected concentration of 20 μg/mL with acetonitrile-methanol and then dilution with mobile phase, the samples were assayed in duplicate using stability-indicating high-performance liquid chromatography. Stability was determined by evaluating the percentage of the initial concentration remaining at each time point; stability was defined as the retention of at least 90% of the initial concentration of thalidomide. At least 92% of the initial thalidomide concentration remained throughout the 35-day study period. There were no detectable changes in color, odor, or pH and no visible microbial growth in any sample. An extemporaneously prepared suspension of thalidomide 20 mg/mL in a 1:1 mixture of Ora-Plus and Ora-Sweet was stable for at least 35 days when stored in 2-oz amber plastic bottles under refrigeration.

    In an effort to minimize barriers to compliance and adherence and to improve the accuracy of dosage measurement, sugar-containing and sugar-free sodium phenylbutyrate suspensions were formulated, and the stability of these products over a 90-day period was determined. An oral suspension of sodium phenylbutyrate 200 mg/mL was prepared by thoroughly grinding 12 g of Sodium Phenylbutyrate Powder, USP, in a glass mortar. Thirty milliliters of Ora-Plus and 30 mL of either Ora-Sweet or Ora-Sweet SF were mixed and added to the powder to make a final volume of 60 mL. Three identical samples of each formulation were prepared and placed in 2-oz amber plastic bottles with child-resistant caps and were stored at room temperature. A 500-microL sample was withdrawn from each of the six bottles with a micropipette immediately after preparation and at 7, 14, 28, 60, and 90 days. After further dilution to an expected concentration of 100 microg/mL with the mobile phase, the samples were assayed by high-performance liquid chromatography. Stability was defined as the retention of at least 90% of the initial concentration. At least 95% of the initial sodium phenylbutyrate concentration remained throughout the 90-day study period in both preparations. There were no detectable changes in color, odor, taste, and pH and no visible microbial growth in any sample. Extemporaneously compounded suspensions of sodium phenylbutyrate, 200 mg/mL, in a 1:1 mixture of Ora-Plus and Ora-Sweet or Ora-Sweet SF were stable for at least 90 days when stored in 2-oz amber plastic bottles at room temperature.

    The physical and chemical short-term stability of alcohol-free, oral suspensions of phenobarbital 10 mg/mL prepared from commercially available tablets in both a sugar and a sugar-free vehicle was assessed at room temperature. Phenobarbital oral suspension 10 mg/mL was prepared by crushing 10 60-mg tablets of phenobarbital with a mortar and pestle. A small amount of Ora-Plus was added to the phenobarbital powder to sufficiently wet the particles. A 1:1 mixture of Ora-Plus and either Ora-Sweet or Ora-Sweet SF was combined with the phenobarbital powder to produce a final volume of 60 mL. Three identical samples of each of the two different formulations were prepared and stored at room temperature in 2-oz amber plastic bottles. Immediately after preparation and at 15, 30, 60, and 115 days, the samples were assayed in duplicate by stability-indicating high-performance liquid chromatography. The samples were tasted and inspected for color and odor changes. The percent of the initial concentration remaining at each study time for each phenobarbital suspension was determined. Stability was defined as the retention of at least 90% of the initial concentration. There were no detectable changes in color, odor, and taste and no visible microbial growth in any sample. At least 98% of the initial phenobarbital concentration remained throughout the 115-day study period in both preparations. An extemporaneously prepared alcohol-free suspension of phenobarbital 10 mg/mL in a 1:1 mixture of Ora-Plus and Ora-Sweet or Ora-Sweet SF was stable for at least 115 days when stored in 2-oz amber plastic bottles at room temperature.

    The stability of extemporaneously prepared moxifloxacin oral suspensions was studied. An oral suspension of moxifloxacin 20 mg/mL was prepared by thoroughly grinding three 400-mg tablets of moxifloxacin in a glass mortar. Thirty milliliters of Ora-Plus and 30 mL of either Ora-Sweet or Ora-Sweet SF were mixed and added to the powder to make a final volume of 60 mL. Three identical samples of each formulation were prepared and placed in 2-oz amber plastic bottles with child-resistant caps and were stored at room temperature (23-25 degrees C). A 1-mL sample was withdrawn from each of the six bottles with a micropipette immediately after preparation and at 7, 14, 28, 60, and 90 days. After further dilution to an expected concentration of 8 microg/ mL with sample diluent, the samples were assayed in duplicate by stability-indicating high-performance liquid chromatography. Stability was defined as the retention of at least 90% of the initial concentration. At least 99% of the initial moxifloxacin remained throughout the 90-day study period in both preparations. There were no detectable changes in color, odor, taste, and pH and no visible microbial growth in any sample. Extemporaneously compounded suspensions of moxifloxacin 20 mg/mL in a 1:1 mixture of Ora-Plus and Ora-Sweet or Ora-Sweet SF were stable for at least 90 days when stored in 2-oz amber plastic bottles at room temperature.
